In general, the metal crystal is very dense, and the penetration depth of the heat radiation to the metal is on the order of micrometers, which reduces the possibility that the infrared heat radiation generated by the heat generating component 40 penetrates the atomizing head sleeve 10, thereby reducing the loss of infrared heat radiation. .

The atomizing head base 20 is substantially a hollow cylindrical structure having openings at both ends, and the upper end of the atomizing head base 20 is inserted into the lower end of the atomizing head sleeve 10, thereby achieving a fixed connection relationship between the two.

In the present embodiment, there are four intake holes 302, and are uniformly disposed on the side wall of the electrode 30 along the circumferential direction of the electrode 30.

In the present embodiment, the inner side wall of the upper end of the electrode 30 is recessed downward to form a step 304, and the upper end of the atomizing head sleeve 10 is provided with a snap ring 109. Specifically, the upper end of the heat generating component 40 is clamped on the snap ring 109 of the atomizing head sleeve 10, and the lower end of the heat generating component 40 is abutted on the step of the electrode 30, so that the heat generating component 40 is not arbitrarily shaken and the mounting is reliable. If the heat generating component 40 includes a frangible component, the fragile component in the heat generating component 40 can be prevented from being broken when the atomizing head 100 is dropped.

Since the heat generating component 40 is disposed at the upper end of the electrode 30, the opening of the upper end of the electrode 30 is closed by the heat generating component 40. In order to allow the external air entering the intake chamber 301 to smoothly flow out into the atomizing head cannula 10, an over-air gap is also provided on the electrode 30. Referring to FIG. 2 , in the embodiment, the upper end of the electrode 30 is recessed downward along the axial direction of the electrode 30 to form four recesses 303 , each of which is respectively associated with the air inlet chamber 301 and the atomizing head sleeve 10 . The inner cavity is in communication, and the groove 303 is the over-air gap, and the external gas entering the air-intake chamber 301 can enter the atomizing head casing 10 through the groove 303 to be mixed with the generated smoke. It can be understood that, in other embodiments not shown, the number of the grooves 303 may also be one, two, three or more, which is not limited herein.

In order to avoid a short-circuit failure between the atomizing head base 20 and the electrode 30, an insulating member 70 is interposed between the atomizing head base 20 and the electrode 30, thereby isolating the atomizing head base 20 from the electrode 30. In the present embodiment, the insulating member 70 is made of a silicone material. It will be appreciated that in other embodiments not shown, the insulating member 70 may also be made of other insulating materials such as rubber.

The atomizing head base 20, the electrode 30, and the insulating member 70 are enclosed to form a collecting chamber 201. When the electronic cigarette is stopped, if there is residual smoke, the residual smoke will be condensed and returned to the liquid state. Under the action of gravity, the condensed liquid will accumulate in the collecting chamber 201 without leaking through the electrode 30, causing leakage. . The user inverts the atomizing head 100, so that the liquid absorbing member 60 adsorbs the liquid smoke in the collecting chamber 201, so that the liquid smoke in the collecting chamber 201 is reused, or the liquid absorbing member 60 can be extended into the collecting chamber 201. In order to adsorb the liquid smoke in the collection chamber 201 in time.

Referring to FIG. 3, the heat generating component 40 includes an infrared radiator 41, a first electrode post 42 mounted at a lower end of the infrared radiator 41, a second electrode post 43 mounted at an upper end of the infrared radiator 41, and a housing received inside the infrared radiator 41. Heating element 44.

The infrared radiator 41 is substantially a hollow cylindrical structure having openings at both ends, and the first electrode column 42 is disposed at a lower end of the infrared radiator 41 by a mounting sealing ring (not shown), and the second electrode column 43 is mounted with a sealing ring ( The figure is not shown) provided at the upper end of the infrared radiator 41. The sealing ring has a sealing function, so that a receiving space is formed between the infrared radiator 41, the first electrode column 42, the second electrode column 43, and the sealing ring. The heating element 44 is housed in the receiving space, and one end of the heating element 44 is electrically connected to the first electrode post 42 , and the other end of the heating element 44 is electrically connected to the second electrode post 43 .

The infrared radiator 41 is made of an infrared radiation material, or the infrared radiator 41 includes a substrate and an infrared radiation material coated on the outer surface of the substrate, so that the infrared radiator 41 can absorb the heat generated by the heating element 44 and emit it outward. Infrared heat radiation. Infrared radiation materials are quartz, carbon, graphite, magnesia, alumina, calcium oxide, titanium oxide, silicon oxide, chromium oxide, iron oxide, manganese oxide, zirconium oxide, hafnium oxide, nickel oxide, copper oxide, cobalt oxide, oxidation. Bismuth, yttrium oxide, cordierite, mullite, boron carbide, silicon carbide, titanium carbide, molybdenum carbide, tungsten carbide, zirconium carbide, niobium carbide, boron nitride, aluminum nitride, silicon nitride, zirconium nitride, nitrogen At least one of titanium, titanium silicide, molybdenum silicide, tungsten silicide, titanium boride, zirconium boride, and chromium boride. The base of the infrared radiator 41 is made of at least one of a metal, an alloy, a ceramic, a quartz, a carbon fiber, and a polyester.

It can be understood that when the infrared radiator 41 has electrical conductivity (for example, the base of the infrared radiator 41 is a metal or an alloy), in order to avoid a short circuit between the infrared radiator 41 and the first electrode column 42 and the second electrode column 43 In case of failure, the sealing ring should also have insulation.

It can be understood that in other embodiments not shown, the heating element 44 can also be sintered in the infrared radiator 41, or coated on the inner surface of the infrared radiator 41, or sandwiched between the infrared radiator 41. between.

When the atomizer is connected to the power supply unit 107, one of the atomizing head sleeve 10 and the electrode 30 is electrically connected to the positive electrode of the power supply unit 107, and the other is electrically connected to the negative electrode of the power supply unit 107. And one of the first electrode column 42 and the second electrode column 43 is in contact with the positive electrode, and the other is used as the negative electrode contact. When mounting, any one of the first electrode column 42 and the second electrode column 43 and the atomizing head cover can be made. The upper end of the tube 10 abuts and the other abuts on the electrode 30 without distinction, making the installation simple and convenient.

In this embodiment, the first electrode post 42 abuts on the electrode 30, so that the first electrode post 42 is in contact with the electrode 30 and electrically connected, and the second electrode post 43 is locked at the upper end of the atomizing head sleeve 10, Therefore, the second electrode post 43 is in contact with the atomizing head sleeve 10 and electrically connected. Therefore, the heating element 44 generates heat under the electric driving of the power supply device 107, and the infrared radiator 41 absorbs the heat generated by the heating element 44, and Infrared heat radiation is emitted outward.

In the present embodiment, the heat generating component 44 is spaced apart from the infrared radiator 41. Specifically, the heat generating component 44 is not in contact with the infrared radiator 41, and a gap is left between the two, so that the service life of the heat generating component 40 can be extended. This is because if the heating element 44 is placed in contact with the infrared radiator 41, the infrared radiator 41 may be brought into contact with the heating element 44. Part of the temperature rises rapidly, and the portion not in contact with the heating element 44 rises slowly, which causes the temperature of the infrared radiator 41 to be uneven, which may cause the infrared radiator 41 to crack, affect the service life of the infrared radiator 41, or cause infrared rays. The infrared radiation material coated on the surface of the radiator 41 is peeled off, so that the infrared radiation efficiency is lowered and the infrared radiation is not uniform. On the other hand, the temperature of the portion where the heat generating element 44 is in contact with the infrared radiator 41 is lower than the temperature of the portion not in contact with the infrared radiator 41, and the temperature of the heat generating element 44 is not uniform, which tends to cause the heat generating element 44 to be broken.

In one of the embodiments, the infrared radiator 41 is filled with an inert gas which prevents the heat generating element 44 from being oxidized at a high temperature. In another embodiment, the infrared radiator 41 is evacuated, and similarly, the heating element 44 can be prevented from oxidizing under high temperature.

In the present embodiment, the heat generating element 44 is a spiral wire, and the wire may be a tungsten wire or a nichrome wire. It can be understood that in other embodiments not shown, the heat generating component 44 can also be made of a carbon fiber material, which has high electrothermal conversion efficiency, high tensile strength, light weight, corrosion resistance, and is not easily oxidized.

The air guiding member 50 is substantially a hollow cylindrical structure having openings at both ends, and the air guiding member 50 is sleeved on the outside of the heat generating component 40. Specifically, the air guiding member 50 is sleeved outside the infrared radiator 41. In the present embodiment, the inner circumferential surface of the air guiding member 50 is disposed in contact with the outer circumferential surface of the infrared radiator 41, so that the heat of the heat generating component 44 absorbed on the infrared radiator 41 can be transmitted to the air guiding member by heat conduction and heat radiation. 50.

In the present embodiment, the air guiding member 50 is a porous member, and at least portions of the holes of the air guiding member 50 communicate with each other such that the upper end surface, the lower end surface, the inner portion and the outer peripheral surface of the air guiding member 50 communicate with each other, and the mutually communicating holes An outlet passage 501 is formed, and the outlet passage 501 is in communication with the groove 303 on the electrode 30. When the user uses it, the external air passing through the groove 303 can pass through the air guide 50 through the air outlet passage 501, and the smoke is carried out from the opening of the upper end of the atomizing head sleeve 10 for the user to use.

It can be understood that the air guiding member 50 can be made of a metal material such as stainless steel or copper, or can be made of a non-metal material such as ceramic.

When the air guiding member 50 is made of a metal material, considering that the metal crystal is generally very dense, the infrared heat radiation generated by the infrared radiator 41 will be almost completely absorbed by the air guiding member 50, and the infrared radiator 41 is guided. The heat transfer of the gas member 50 allows the gas guide member 50 to rise to a higher temperature to heat the smoke liquid on the liquid suction member 60 by the heat conduction of the gas guide member 50 to generate smoke. Compared with the conventional heating type heating wire, the heating wire may generate local high temperature at the moment of energization, and the liquid absorbing member 60 may be scorched at an instantaneous high temperature to generate an odor, thereby affecting the user's use. In the present embodiment, the air guiding member 50 itself is not a heat generating member. Therefore, local high temperature is not generated instantaneously, and the air guiding member 50 uniformly heats up under the action of heat radiation and heat conduction of the heat generating component 40, and then uniformly heats the liquid absorbing member 60. The above liquid smoke can obtain a better mouthfeel and reduce the risk of the liquid suction member 60 being burnt. In addition, after the heating element 44 and the infrared radiator 41 are determined, the wavelength of the infrared ray generated by the heat generating component 40 is determined. In the market, the composition of the smoke liquid is various, and the molecular vibration wavelengths of different smoke liquids are also different. Thus, the absorption effect of the infrared heat radiation generated by the heat generating component 40 is also different. When the gas guide member 50 is made of a metal material, the difference can be reduced because the gas guide member 50 itself absorbs infrared heat radiation and then heats the smoke liquid by heat conduction. In one of the embodiments, the air guide 50 is a metal mesh.

When the air guiding member 50 is made of a non-metal material, the molecular structure of the non-metal material is generally loose, and most of the infrared heat radiation generated by the infrared radiator 41 can pass through the air guiding member 50, and the air guiding member 50 is in the infrared radiator. The heat conduction and heat radiation of 41 cannot be heated to a higher temperature, and the smoke liquid is atomized into smoke mainly by the heating of infrared heat radiation passing through the air guide member 50. When the molecular vibration wavelength of the smoke liquid matches the wavelength of the infrared light generated by the heat generating component 40, this A heating method is advantageous. This is because this heating method reduces the heat loss caused by the air guide 50.

It can be understood that, after the air guiding member 50 is disposed, it is not necessary to form a groove on the outer surface of the infrared radiator 41 as an air outlet passage, so that the mechanical strength of the infrared radiator 41 can be avoided. The thickness of the infrared radiator 41 is prevented from being different, and the ability of each part of the infrared radiator 41 to absorb heat is different, so that the infrared radiation body 41 has different ability to emit infrared heat radiation, thereby affecting the heat generating component 40 to the smoke liquid. The heating effect.

It can be understood that when the air guiding member 50 is made of a metal material, since the air outlet passage 501 is formed by the communication of the air passage member 50, it is not necessary to open a groove on the outer surface of the air guiding member 50 as the air outlet. The passage, the air guiding member 50 and the liquid absorbing member 60 can be uniformly contacted, and the liquid smoke can be heated uniformly. When the air guiding member 50 is made of a non-metal material, since the air outlet passage 501 is formed by the communication of the air guiding member 50, it is not necessary to open a groove on the outer surface of the air guiding member 50 as an air outlet passage. The thickness of the gas member 50 is uniform, so that the infrared heat radiation passing through the gas guiding member 50 is uniform, thereby making the liquid smoke uniform in heat.

The liquid absorbing member 60 is substantially a hollow cylindrical structure having openings at both ends, and the liquid absorbing member 60 is interposed between the atomizing head sleeve 10 and the air guiding member 50, and the outer peripheral surface of the liquid absorbing member 60 and the atomizing head sleeve 10 The inner peripheral surface of the liquid absorbing member 60 is disposed in contact with the outer peripheral surface of the air guiding member 50. It can be understood that the liquid absorbing member 60 is attached to the liquid inlet hole 101 of the atomizing head sleeve 10, that is, The liquid hole 101 is provided at a position where the atomizing head cannula 10 is in contact with the liquid suction member 60. The liquid absorbing member 60 has the ability to absorb and store the liquid smoke, and the liquid absorbing member 60 is one or a combination of two or more of porous ceramics, cotton, cotton cloth, fiber rope, metal foam, foamed graphite, activated carbon, and the atomizer. The stored soot liquid can be absorbed by the liquid suction member 60 via the liquid inlet hole 101.

When the user ingests, the smoke liquid on the liquid suction member 60 is heated by the heat radiation action of the heat generating component 40 and/or the heat conduction of the air guiding member 50, thereby causing the liquid smoke to atomize to form smoke. Under the suction of the user, the smoke enters into the air outlet passage 501 of the air guide member 50 to be mixed with the external air, and finally enters the user's mouth under the action of the external air. The direction indicated by the arrow in Fig. 3 is the direction of the air flow.

Referring to FIG. 4, in order to shorten the temperature rise time between the user's two cigarettes, the electronic cigarette provided by the present invention is further provided with a heat preservation mechanism. Specifically, a small cigarette key 108 is mounted on the outer casing of the electronic cigarette, and a controller 102 and a timer 103 are disposed in the outer casing of the electronic cigarette, and the controller 102 and the cigarette light key 108, the power supply device 107, the heating element 44, and the timer 103 are both disposed. Electrical connection. The controller 102 stores a preset time, for example, 10 s.

When the controller 102 detects the activation signal from the cigarette light key 108, the controller 102 controls the electronic cigarette to enter the heating mode. Specifically, the controller 102 controls the power supply device 107 to output the first heating power to the heating element 44.

When the controller 102 detects that the activation signal from the cigarette light key 108 is interrupted, the controller 102 controls the electronic cigarette to enter the warm-up mode and controls the timer 103 to count. Before the timer 103 counts the time to reach the preset time, the controller 102 determines whether The start signal is detected. If the controller 102 detects the start signal, the controller 102 controls the electronic cigarette to switch from the warm mode to the heating mode. If the controller 102 does not detect the start signal, the controller 102 controls the electronic cigarette to remain in the warm mode. When the time when the electronic cigarette is maintained in the warm-up mode reaches a preset time, the controller 102 controls the electronic cigarette to enter a shutdown state. It can be understood that, wherein the controller 102 controls the electronic cigarette to enter the warm-up mode, the controller 102 controls the power supply device 107 to output the second heating power to the heating element 44, and the second heating power is less than the first heating power. The shutdown state of the electronic cigarette means that the power supply unit 107 stops supplying power to any of the electronic components and the heating element 44 in the electronic cigarette.

In the present embodiment, the cigarette light key 108 is a mechanical button, and the user presses the cigarette light key 108 so that the signal output end of the cigarette light key 108 is in contact with the detecting end of the controller 102, so that the controller 102 detects the cigarette light key 108. The start signal sent. When the user releases the cigarette light button 108, the signal output end of the cigarette light button 108 is in contact with the detecting end of the controller 102. The state becomes a phase separated state, thereby causing the controller 102 to detect that the activation signal from the cigarette light key 108 is interrupted.

It should be noted that the preset time, the first heating power, and the second heating power may be set by the factory, or may be set by the user according to the usage requirements.

When the user presses the cigarette light button 108, the workflow of the electronic cigarette is as follows:

In step S101, the controller 102 receives the activation signal from the cigarette light key 108, and then proceeds to step S102.

In step S102, the controller 102 controls the electronic cigarette to enter the heating mode, that is, the controller 102 controls the power supply device 107 to output the first heating power to the heating element 44.

When the user releases the cigarette light button 108, the workflow of the electronic cigarette is as follows:

In step S201, the controller 102 detects that the activation signal from the cigarette light key 108 is interrupted, and then proceeds to step S202.

In step S202, the controller 102 controls the electronic cigarette to enter the warm-up mode, that is, the controller 102 controls the power supply device 107 to output the second heating power to the heating element 44, and controls the timer 103 to count, and then proceeds to step S203.

In step S203, the controller 102 determines whether the time counted by the timer 103 reaches a preset time. If the time counted by the timer 103 reaches the preset time, the process proceeds to step S204; if the time counted by the timer 103 does not reach the preset time, Go to step S205.

In step S204, the controller 102 controls the electronic cigarette to enter a shutdown state.

In step S205, the controller 102 determines whether the activation signal sent by the cigarette light key 108 is detected. If the determination result is YES, the process proceeds to step S206; if the determination result is negative, the process proceeds to step S207.

In step S206, the controller 102 controls the electronic cigarette to enter the heating mode.

In step S207, the controller 102 controls the timer 103 to continue counting, and then proceeds to step S203.

In addition, referring to FIG. 11, the electronic cigarette of the present invention is further provided with a countermeasure mechanism for cracking or peeling of the infrared radiator 41 to ensure that when the infrared radiator 41 is broken or peeled off, the user can know in time to replace the heating component in time. 40. It can be understood that if the countermeasure mechanism for the cracking or peeling of the infrared radiator 41 is not provided, the user will not know that the infrared radiator 41 has broken or the infrared radiation material coated on the surface of the substrate has peeled off. Especially when the heating element 44 is still functioning properly, it is difficult for the user to recognize that the heating element 40 needs to be replaced. However, the cracking or peeling of the infrared radiator 41 affects the amount of infrared heat radiation generated by the heat generating component 40 and the wavelength range, thereby affecting the atomization effect. On the other hand, the ruptured or exfoliated infrared radiator 41 may be mixed into the smoke and may be inhaled by the user. Therefore, even if the heat generating element 44 can operate normally, the infrared radiator 41 is broken or peeled off, and the user still needs to replace the heat generating component 40 in time.

Three specific structures for dealing with cracking or spalling of the infrared radiator 41 are given herein.

Referring to FIG. 7, in the first configuration, a signal detecting layer 413 is interposed in the wall of the infrared radiator 41. Referring to FIG. 8, in the second structure, the signal detecting layer 413 is coated on the outer wall of the infrared radiator 41. Referring to FIG. 9, in the third configuration, the signal detecting layer 413 is coated on the inner wall of the infrared radiator 41. Among them, the signal detecting layer 413 is made of an infrared transmitting material which can change resistance or potential with deformation. As such, the signal detecting layer 413 does not hinder the heat generating component 40 from emitting infrared heat radiation, and the signal detecting layer 413 also generates a resistance or potential change when deformation occurs.

When the infrared radiator 41 is made of an infrared radiation material, it is necessary to cope with the case where the infrared radiator 41 is broken. When the infrared radiator 41 is broken, the signal detecting layer 413 is deformed in the above three structures, and therefore, the three structures can be arbitrarily selected and used.

When the infrared radiator 41 is composed of a substrate and an infrared radiation material coated on the outer surface of the substrate, it is necessary to cope with Yes, the case where the infrared radiation material peels off from the substrate. When the infrared radiation material is peeled off, in the first and third structures described above, since the signal detection layer 413 is not in contact with the infrared radiation material, the signal detection layer 413 is not deformed, and the second structure should be selected.

Referring to FIG. 11 again, the electronic cigarette of the present invention further includes a reminder device 106. The controller 102 is electrically connected to the signal detecting layer 413, the power source device 107, and the reminding device 106, respectively. The reference resistor/potential and a preset range are pre-stored in the controller 102.

The reference resistance/potential refers to the resistance/potential of the signal detecting layer 413 when the infrared radiator 41 operates normally (without cracking or peeling) at normal temperature.

The preset range refers to the allowable range of the difference between the resistance/potential of the signal detecting layer 413 and the reference resistance/potential when the heat generating component 40 operates, that is, when the difference between the two is not within the preset range, then It is considered that the infrared radiator 41 is broken or peeled off, and when the difference between the two is within the preset range, it is considered that the infrared radiator 41 is not cracked or peeled off, that is, the infrared radiator 41 is in a normal working state.

In one of the embodiments, when setting the preset range, the main consideration is the effect of temperature. This is because even if the infrared radiator 41 is in a normal working state, the infrared radiator 41 may be inflated by the action of temperature, for example, by the heating of the heating element 41 or by placing the electronic cigarette in a cold environment. The deformation occurs at the time of cold shrinkage, and at this time, the signal detecting layer 413 is deformed (expanded or contracted), resulting in a change in the resistance/potential of the signal detecting layer 413.

When the signal detecting layer 413 is being changed, when the signal detecting layer 413 is expanded, the resistance/potential is increased, and when the signal detecting layer 413 is contracted, the resistance/potential is decreased. When the electronic cigarette is at the lowest use temperature, the infrared radiator 41 is in a normal working state, and the detected resistance/potential of the signal detecting layer 413 is the minimum resistance/potential; when the electronic cigarette is at the highest use temperature, the infrared radiator When the 41 is in a normal operating state, the detected resistance/potential of the signal detecting layer 413 is the maximum resistance/potential. The minimum operating temperature is the minimum ambient temperature that an electronic cigarette can withstand. The maximum use temperature refers to the upper limit of the operating temperature that the heating element 41 can allow. The lower limit of the preset range is the difference between the minimum resistance/potential and the reference resistance/potential. The upper limit of the preset range is the difference between the maximum resistance/potential and the reference resistance/potential.

When the signal layer 413 of negative change is employed, when the signal detecting layer 413 is expanded, the resistance/potential is decreased, and when the signal detecting layer 413 is contracted, the resistance/potential is increased. When the electronic cigarette is at the lowest use temperature, the infrared radiator 41 is in a normal working state, and the detected resistance/potential of the signal detecting layer 413 is the maximum resistance/potential; when the electronic cigarette is at the highest use temperature, the infrared radiator When the 41 is in a normal operation state, the detected resistance/potential of the signal detecting layer 413 is the minimum resistance/potential. The minimum operating temperature is the minimum ambient temperature that an electronic cigarette can withstand. The maximum use temperature refers to the upper limit of the operating temperature that the heating element 41 can allow. The lower limit of the preset range is the difference between the minimum resistance/potential and the reference resistance/potential. The upper limit of the preset range is the difference between the maximum resistance/potential and the reference resistance/potential.

Referring to FIG. 12, the implementation process of the countermeasure mechanism for the rupture or spalling of the infrared radiator 41 is as follows:

In step S301, the controller 102 detects the resistance/potential of the signal detecting layer 413, and then proceeds to step S302.

Step S302, the controller 102 compares the detected resistance/potential with the reference resistance/potential, and determines whether the difference between the two is within a preset range. When the difference between the two is not within the preset range, the step is entered. S303. When the difference between the two is within the preset range, the process proceeds to step S304.

In step S303, the controller 102 controls the reminder device 106 to issue an alarm message. The alarm information is used to remind the user that the infrared radiator 41 is in a broken or peeling state, and the heat generating component 40 needs to be replaced in time.

In step S304, the controller 102 controls the reminder device 106 to issue security information. The security information is used to alert the user The infrared radiator 41 is in a normal working state, and the heat generating component 40 can be normally used.

The reminder device 106 may be a speaker, a display light, a display screen or a vibrating device or the like disposed on the electronic cigarette. It will be appreciated that in other embodiments not shown, the reminder device 106 may be omitted. When the detected difference between the resistance/potential and the reference resistance/potential is not within the preset range, the controller 102 controls the power supply device 107 to stop supplying power to the heat generating component 40, thereby reminding the user that the infrared radiator 41 is in a broken or peeling state, The heat generating component 40 needs to be replaced in time.

A start button may be disposed on the electronic cigarette, and the user may operate the start button to generate a trigger signal. When the controller 102 detects the trigger signal, the electronic cigarette initiates a countermeasure mechanism for the infrared radiator 41 to rupture or peel off, that is, the electronic cigarette proceeds to step S301- S304. In this way, the user can detect the state of the infrared radiator 41 at any time according to his own needs.

Alternatively, after the electronic cigarette completes step S101, that is, when the controller 102 detects the activation signal sent by the cigarette light key 108, the electronic cigarette first proceeds to steps S301 and S302, and if it is determined according to the result of step S302, it can proceed to step S304. Then, after step S304, the process proceeds to step S102. Alternatively, when the step S302 is performed, if the result of the determination is that the difference between the two is within the preset range, the process proceeds directly to step S102, and step S304 is omitted. Thus, before the heat generating component 40 is operated, the infrared radiator 41 is first detected, and when the infrared radiator 41 is in a normal state, the heat generating component 40 is operated, and the infrared radiator 41 can be prevented from working in a state of being cracked or peeled off. .

Referring again to FIG. 8, in the second configuration, since the signal detecting layer 413 is coated on the outer wall of the infrared radiator 41, the cracked or peeled infrared radiator 41 can be dropped to the signal detecting layer 413. Prevent mixing into the smoke in the space. For the first and third structures, referring to FIG. 10, a protective film 414 may be coated on the outer peripheral surface of the infrared radiator 41, and the protective film 414 is made of an infrared transmitting material. When the infrared radiator 41 is cracked or peeled off, the cracked or peeled infrared radiator 41 can only fall in the space composed of the protective film 414 to prevent mixing into the smoke.

According to the atomization head 100 provided by the present invention, the heat generated by the heating element 44 is absorbed by the infrared radiator 41, and the infrared radiator 41 emits infrared heat radiation, and the infrared liquid of the smoke liquid on the liquid absorption member 60 in the infrared radiator 41 The radiation and/or the heat conduction of the gas guiding member 50 generates smoke for the user to suck, avoiding the occurrence of oxidation and carbonization of the heating element 44 in contact with the liquid absorbing member 60. The atomizer and the electronic cigarette provided by the present invention have the same technical features as the atomizing head 100 described above because they have all the technical features of the atomizing head 100 described above.

Embodiment 2

Referring to FIG. 13, the electronic cigarette provided in the second embodiment of the present invention is different from the electronic cigarette in the first embodiment in that the structure of the atomizing head 200 on the atomizer in the electronic cigarette of the second embodiment is different. Specifically, in the second embodiment, the air guiding member 50 and the infrared radiator 41 are spaced apart, that is, when the air guiding member 50 is sleeved outside the infrared radiator 41, the inner circumferential surface of the air guiding member 50 and the infrared There is a gap 502 between the outer peripheral faces of the radiator 41. The gap 502 separates the air guide 50 from the infrared radiator 41, so that the air guide 50 does not contact the infrared radiator 41, and there is no heat conduction between the two. .

It can be understood that, in the first embodiment, it is difficult to ensure the uniformity of contact between the air guiding member 50 and the infrared radiator 41, and the portion where the two contacts more, the heat transfer is faster, and the contact between the two is less. The heat transfer is slower, so that the air guide 50 is unevenly heated, thereby affecting the heating effect of the air guide 50 on the liquid smoke on the liquid suction member 60. On the other hand, when the contact between the two is large, the infrared radiator 41 cools faster, and the infrared radiation body 41 cools more slowly, so that the infrared radiator 41 is unevenly heated and cooled. Thereby, the infrared radiator 41 is broken or peeled off. In the second embodiment, since the air guiding member 50 and the infrared radiator 41 are spaced apart from each other, there is no heat conduction process between the two, thereby avoiding the uneven heating of the air guiding member 50, and avoiding the infrared radiator 41 being cold. A condition in which the heat is uneven and cracked or peeled off.

In the embodiment, the air guiding member 50 is a porous member, and the holes on the air guiding member 50 communicate with each other to form an air passage. 501.

In the first embodiment and the second embodiment, in order to prevent infrared heat radiation from passing through the outer casing of the electronic cigarette, energy is wasted, and the inner surface of the electronic cigarette outer casing is coated with a reflective layer, for example, a silver film, which can reflect Infrared heat radiation prevents the infrared heat radiation generated by the atomizing head (100, 200) from leaking out, causing heat loss.

When the outer casing of the electronic cigarette is made of a metal material, the inner surface of the outer casing can be polished to reduce the roughness of the inner surface of the outer casing, so that the inner surface of the outer casing forms a mirror surface, which can also reflect infrared heat radiation and reduce infrared heat radiation. Loss.

In view of the above-described embodiments of the present invention, various changes and modifications can be made by those skilled in the art without departing from the scope of the invention. The technical scope of the present invention is not limited to the contents of the specification, and the technical scope thereof must be determined in accordance with the scope of the claims.
