Referring to fig. 1 and 2, an electronic atomization device 10 according to an embodiment of the present invention includes an atomizer 101 and a power supply 300, wherein the atomizer 101 includes an atomization component 100 and a magnetic component 200. The electronic atomizing device 10 is provided with an air flow channel 110, and the air flow channel 110 is a channel through which external air enters the inside of the electronic atomizing device 10 from at least one inlet and reaches an outlet for a user to suck. The electronic atomizing device 10 may include one or more air flow channels 110, e.g., the air flow channels 110 are all open on the atomizing assembly 100, the magnetic assembly 200 may be located inside the air flow channels 110, or the magnetic assembly 200 may be located outside the air flow channels 110 and near a port of the air flow channels 110, and the power supply 300 is disposed opposite the atomizing assembly 100.
In some embodiments, the atomizing assembly 100 is used to store a gas for the aerosol-generating substrate while the aerosol-generating substrate can be heated for atomization. The aerosol generating substrate is atomized to form a mist which is circulated in the airflow passage 110, and the upper end of the airflow passage 110 forms a nozzle 112 on the atomizing assembly 100, the nozzle 112 being in communication with the outside.
The atomizing assembly 100 is further provided with an air inlet hole 121, for example, the air inlet hole 121 is disposed on a side surface or a bottom surface of the atomizing assembly 100, and the air inlet hole 121 is disposed away from the suction nozzle 112. The air intake holes 121 communicate the air flow passage 110 with the outside. When the suction is performed from the mouthpiece 112, the external air enters the airflow passage 110 from the air inlet hole 121 to form a suction airflow, and the suction airflow passes through the airflow passage 110 to carry the aerosol-generating substrate-atomized smoke into the user's mouth through the mouthpiece 112, thereby achieving the suction of the smoke by the user.
The power supply 300 is connected with the atomizing assembly 100, the power supply 300 comprises a battery 310, a sensing unit 320, a processing unit 330 and a shell, the battery 310, the sensing unit 320 and the processing unit 330 are all accommodated in the shell, the sensing unit 320 can be accommodated in the shell and also can be installed on the atomizing assembly 100, and the sensing unit 320 and the processing unit 330 are all electrically connected with the battery 310. When the battery 310 heats the atomizing assembly 100, the atomizing assembly 100 atomizes the aerosol-generating substrate and the atomized aerosol is drawn through the mouthpiece 112 for inhalation by a user. When the battery 310 stops heating the atomizing assembly 100, the atomizing assembly 100 stops atomizing the aerosol-generating substrate and the atomizing assembly 100 will not produce aerosol for the user to draw. The sensing unit 320 may be a magnetic sensor, and the processing unit 330 may be a single chip microcomputer (Microcontroller Unit, MCU), etc., where the sensing unit 320 is configured to sense a changed magnetic field signal (the changed magnetic field signal includes a change in a magnetic field direction, a change in a magnetic field size, and a simultaneous change in a magnetic field direction and a magnetic field size), and transmit the changed magnetic field signal to the processing unit 330, where the processing unit 330 is configured to analyze and determine the changed magnetic field signal, and the processing unit 330 is capable of controlling whether the battery 310 heats the atomizing assembly 100, thereby achieving the purpose of atomizing the aerosol-generating substrate.
When the magnetic assembly 200 is positioned in the airflow channel 110, the magnetic assembly 200 may be positioned near the power supply 300, and when the user sucks in the nozzle 112, the magnetic assembly 200 can move relative to the atomizing assembly 100 under the pushing action of the sucked air flow, and the sensing unit 320 receives the varying magnetic field signal generated by the movement of the magnetic assembly 200. In some embodiments, the sensing unit 320 is disposed at a location of the battery 310 proximate to the atomizing assembly 100, e.g., the sensing unit 320 is disposed below the atomizing assembly 100. This facilitates the sensing unit 320 to accurately and rapidly sense the varying magnetic field signal generated by the movement of the magnetic assembly 200, improving the sensitivity of the sensing unit 320 and the response speed of the entire electronic device to the user's suction.
The processing unit 330 has a good filtering function, and in the process of analyzing the changing magnetic field signal, the processing unit 330 can accurately determine whether the changing magnetic field signal is a normal suction signal generated by the user sucking the air flow to push the magnetic assembly 200 to move. For example, when the magnetic assembly 200 vibrates due to abnormal interference such as external impact to induce a varying magnetic field signal, the processing unit 330 can effectively exclude the interference information so that the battery 310 does not heat the atomizing assembly 100 to atomize the aerosol-generating substrate. Thus, the processing unit 330 is able to react to the control of the heating of the atomizing assembly 100 by the battery 310 only when the varying magnetic field signal is a normal pumping signal, and the processing unit 330 is not able to react to the control of the heating of the atomizing assembly 100 by the battery 310 when the varying magnetic field signal is induced by other external factors such as non-pumping air flow. In fact, referring to fig. 9, the sensing unit 320 senses that the signal generated by the abnormal interference such as the external impact is an irregular signal, and referring to fig. 10, the sensing unit 320 senses that the signal generated by the suction air flow is a regular signal, so the processing unit 330 can easily determine whether the signal is generated by the suction air flow by analyzing whether the signal exhibits a certain rule.
In some embodiments, power supply 300 further includes an attitude sensor disposed on the housing. The gesture sensor is used for sensing a changing magnetic field signal generated by the movement of the magnetic component 200 caused by abnormal interference such as external vibration, and the gesture sensor does not transmit the changing magnetic field signal to the processing unit 330 for analysis and filtering processing, so that the battery 310 is prevented from heating the atomization component 100 due to the changing magnetic field signal, and the gesture sensor can be understood as replacing the filtering function of the processing unit 330 on interference information, and the reaction speed of the processing unit 330 is improved. At the same time, the attitude sensor is also able to sense a changing magnetic field signal from the outside that is not induced by the movement of the magnetic assembly 200, and as such, the attitude sensor will also prevent the changing magnetic field signal from being transmitted to the processing unit 330.
When the magnetic assembly 200 is disposed inside the airflow channel 110 of the atomizing assembly 100, the magnetic assembly 200 can fully utilize the space of the existing airflow channel 110 without occupying space outside the airflow channel 110, so that the entire electronic atomizing device 10 is more compact. Meanwhile, the power supply 300 receives the varying magnetic field signal generated by the movement of the magnetic assembly 200, and can rapidly judge the varying magnetic field signal and control the heating of the atomizing assembly 100 accordingly, so as to improve the starting sensitivity of the electronic atomizing device 10.
Referring also to fig. 1-4, in some embodiments, the magnetic assembly 200 includes two magnetic units, and when suction is applied from the suction nozzle 112, the suction air flow from the air inlet hole 121 into the air flow channel 110 will push the two magnetic units to slide relative to each other, thereby changing the spacing between the two magnetic units to generate a magnetic field strength variation.
Specifically, the two magnetic units are respectively denoted as a fixed magnetic unit 210 and a sliding magnetic unit 220, and the fixed magnetic unit 210 is fixed at a position distant from the nozzle 112. The sliding magnetic unit 220 is slidably disposed in the air flow channel 110, the sliding magnetic unit 220 is disposed above the fixed magnetic unit 210, when suction is performed from the nozzle 112, a space above the sliding magnetic unit 220 of the air flow channel 110 forms a certain vacuum, and because the space below the sliding magnetic unit 220 of the air flow channel 110 is communicated with the outside through the air inlet hole 121, an air pressure difference exists between the upper side and the lower side of the sliding magnetic unit 220, and finally, under the pushing of the suction air flow moving from bottom to top in the air flow channel 110, the sliding magnetic unit 220 moves towards the nozzle 112 and away from the fixed magnetic unit 210 (i.e. moves upwards), that is, the distance between the fixed magnetic unit 210 and the sliding magnetic unit 220 changes, and during the increasing of the distance, the magnetic field strength of the whole magnetic assembly 200 at the position of the sensing unit 320 also changes, at this time, the sensing unit 320 senses the changing magnetic field signal, so that the processing unit 330 analyzes the changing magnetic field signal to control the battery 310 to heat the atomizing assembly 100. Of course, when the suction is stopped, the sliding magnetic unit 220 moves towards the fixed magnetic unit 210 and away from the nozzle 112 (i.e. moves downwards) under the action of gravity and magnetic attraction force, the distance between the fixed magnetic unit 210 and the sliding magnetic unit 220 is reduced, and the sensing unit 320 can sense the changing magnetic field signal of the position where the sensing unit 320 is located in the process of reducing the distance, but since the processing unit 330 has the filtering function, the processing unit 330 can accurately determine that the changing magnetic field signal is not caused by the suction airflow pushing the magnetic assembly 200 to move, so the processing unit 330 will not control the battery 310 to heat the atomizing assembly 100.
The electronic atomizing device 10 further includes a first protrusion 141 and a second protrusion 142, where the shapes of the first protrusion 141 and the second protrusion 142 may be substantially the same, and when the airflow channel 110 is cylindrical, the first protrusion 141 and the second protrusion 142 are both circular, edges of the first protrusion 141 and the second protrusion 142 are both connected with an inner wall of the airflow channel 110, the first protrusion 141 is disposed near the nozzle 112, and a first communication hole 141a is disposed on the first protrusion 141, and the first communication hole 141a can allow air to flow therethrough to prevent the first protrusion 141 from blocking the airflow channel 110. The second protrusion 142 is disposed near the fixed magnetic unit 210, and similarly, a second communication hole 142a is disposed on the second protrusion 142, and the second communication hole 142a can allow the air flow to pass therethrough, preventing the second protrusion 142 from blocking the air flow passage 110. The second protrusion 142 is located between the first protrusion 141 and the fixed magnetic unit 210, and the first protrusion 141, the sliding magnetic unit 220, the second protrusion 142, and the fixed magnetic unit 210 are sequentially arranged along the air flow channel 110 from top to bottom. Referring to fig. 3, when suction is performed from the suction nozzle 112, the sliding magnetic unit 220 moves upward until it abuts against the first protrusion 141, and the first protrusion 141 limits the limiting distance of the movement of the sliding magnetic unit 220 toward the suction nozzle 112. Referring to fig. 2, when the suction is stopped, the sliding magnetic unit 220 moves downward until abutting against the second protrusion 142, and the second protrusion 142 limits the limiting distance that the sliding magnetic unit 220 moves away from the suction nozzle 112. At this time, there is no direct contact relationship between the sliding magnetic unit 220 and the fixed magnetic unit 210 due to the isolation of the second bump 142, so that the sliding magnetic unit 220 is more easily moved upward by getting rid of the attractive force of the fixed magnetic unit 210 during suction. Therefore, the first and second protrusions 141 and 142 provide a well-defined stroke of the sliding magnetic unit 220. Of course, the first protrusion 141, the sliding magnetic unit 220, the fixed magnetic unit 210, and the second protrusion 142 may be sequentially arranged from top to bottom along the air flow channel 110, the second protrusion 142 may strengthen the fixing of the fixed magnetic unit 210, and the second protrusion 142 may even be omitted. In other embodiments, each magnetic unit in the magnetic assembly 200 is slidable, the first protrusion 141 and the second protrusion 142 may be replaced by grooves formed on the inner wall of the air flow channel 110, and the upper and lower sidewalls of the grooves may define the stroke of the sliding magnetic unit 220.
Referring also to fig. 2 to 4, it is worth mentioning that both the first communication hole 141a and the second communication hole 142a may be circular, and at the same time, the sliding magnetic unit 220 and the fixed magnetic unit 210 may be bar-shaped permanent magnets or electromagnetic solenoids. Because the strip permanent magnet or the electromagnetic solenoid is in a strip shape, when the sliding magnetic unit 220 is abutted against the first bump 141, the strip-shaped sliding magnetic unit 220 cannot block the whole circular first communication hole 141a, so that air flow can circulate from the part of the first communication hole 141a which is not blocked, and the user can suck smoke. Similarly, the long fixed magnetic unit 210 cannot block the entire circular second communication hole 142 a.
Referring to fig. 5, the fixed magnetic unit 210 may be removed such that the magnetic assembly 200 includes only one sliding magnetic unit 220, as is the case with other conditions of the above-described embodiments. At this time, the sliding magnetic unit 220 is slid between the first and second protrusions 141 and 142, and the first and second protrusions 141 and 142 limit the limited distance of the sliding magnetic unit 220 moving toward or away from the nozzle 112, i.e., limit the limited stroke of the sliding magnetic unit 220 moving up and down. When suction is performed from the nozzle 112, the sliding magnetic unit 220 moves upward toward the nozzle 112, and during the movement, the magnetic field strength of the sliding magnetic unit 220 at the position of the sensing unit 320 also changes due to the change in the distance between the sliding magnetic unit 220 and the sensing unit 320. Of course, the magnetic assembly 200 may further include an elastic body 221, the elastic body 221 may be a spring or a membrane, etc., one end of the elastic body 221 is fixed on the second bump 142, the other end of the elastic body 221 is fixed on the sliding magnetic unit 220, when the suction nozzle 112 sucks the air, the sliding magnetic unit 220 moves upward against the elastic force of the elastic body 221, and when the suction is stopped, the elastic body 221 may provide a restoring force, so that the sliding magnetic unit 220 moves to a position abutting against the second bump 142 quickly.
Referring also to fig. 1, 6 and 7, in some embodiments, the magnetic assembly 200 includes two magnetic units, and when suctioned from the nozzle opening 112, the suction air flow from the air inlet aperture 121 into the air flow channel 110 will urge the two magnetic units to rotate relative to each other, thereby changing the spacing between the two magnetic units to produce a change in magnetic field strength.
Specifically, the two magnetic units are respectively denoted as a fixed magnetic unit 230 and a rotating magnetic unit 240, and the fixed magnetic unit 230 is fixed at a position close to the nozzle 112. The rotating magnetic unit 240 is rotatably disposed at a position far from the suction nozzle 112, and the rotating magnetic unit 240 may be disposed opposite to the air inlet 121, so that when suction is performed from the suction nozzle 112, the suction air flow entering the air flow channel 110 from the air inlet 121 pushes the rotating magnetic unit 240 under the action of vacuum force, and the magnetic field intensity of the whole magnetic assembly 200 at the position of the sensing unit 320 changes during the rotation of the rotating magnetic unit 240. The fixed magnetic unit 230 and the rotating magnetic unit 240 may be bar-shaped permanent magnets or electromagnetic solenoids, and of course, the fixed magnetic unit 230 employs bar-shaped permanent magnets or electromagnetic solenoids, and the rotating magnetic unit 240 employs flat-plate-shaped permanent magnets. In the case that the airflow passage 110 is cylindrical, the rotary magnetic unit 240 rotates around the rotary shaft 241, and the rotary shaft 241 is parallel to or coincident with the central axis of the airflow passage 110, i.e., the rotary shaft 241 is vertically disposed, and of course, the rotary shaft 241 may be vertically disposed with respect to the central axis of the airflow passage 110, i.e., the rotary shaft 241 is laterally disposed. In other embodiments, each of the magnet units in the magnet assembly 200 is rotatable. The magnetic assembly 200 may also include only one rotating magnetic unit 240.

In some embodiments, the movement of the magnetic assembly 200 relative to the airflow channel 110 may be sliding, rotating, a combination of sliding and rotating, or the like. The sensing unit 320, such as a magnetic sensor, receives a signal to sense a varying magnetic field, including a change in the direction of the magnetic field, a change in the magnitude of the magnetic field, or a simultaneous change in the direction and magnitude of the magnetic field. The induction unit 320 transmits the variable magnetic field signal to the processing unit 330 such as the single chip microcomputer, the processing unit 330 analyzes the variable magnetic field signal, and if the variable magnetic field signal is determined to be caused by normal suction airflow, the battery 310 is controlled to heat the atomizing assembly 100, and if the variable magnetic field signal is determined to be caused by external impact or external magnetic field, the battery 310 is controlled not to heat the atomizing assembly 100. Of course, the posture sensor may also be directly used to sense a signal of a changing magnetic field caused by an abnormal air flow, such as an external impact or an external magnetic field, and stop transmitting the signal of the changing magnetic field caused by the abnormal air flow to the processing unit 330, so that the processing unit 330 cannot receive the signal of the changing magnetic field caused by the abnormal air flow, i.e. the posture sensor has a filtering function for eliminating interference information.
The control method can improve the starting sensitivity on the basis of enabling the electronic atomization device to be compact in structure.
