Referring to FIGS. 3, 4 and 5 at the same time, the atomizer 11 includes an upper cover 100, a receiving member 200, a shield 300, a sealing member 400 and a heating element 510. The upper cover 100 can contain the partition cover 300 and the receiving member 200, and the upper cover 100 can be made of a material with good heat insulation performance. The upper cover 100 has a substantially cylindrical structure, and the cross-section of the upper cover 100 may be substantially in the shape of a racetrack. The upper cover 100 encloses an open cavity 120 with a one-sided opening. The upper cover 100 is also provided with an opening 130 which communicates with the open cavity 120, and the cigarette 20 can be inserted into the opening 130. The upper cover 100 and the receiving member 200 may also be integrally formed, that is, as one element, that is, extending downward from the inner surface of the top wall of the upper cover 100 to form the receiving member 200.

The receiving member 200 includes an outer sleeve 210 and an inner tube 220, the outer sleeve 210 and the inner tube 220 are connected to each other, and the receiving member 200 may be made of a material with good heat insulation performance. The outer sleeve 210 has a cylindrical structure approximately the same shape as the upper cover 100, the outer sleeve 210 is received in the open cavity 120 of the upper cover 100, and the inner tube 220 is received in the outer sleeve 210. The inner tube 220 includes a side cylinder 221 and a bottom plate 222.

Branch 20.

When the cigarette 20 is located in the accommodating cavity 223, the end of the cigarette 20 abuts against the upper surface of the bottom plate 222, and the upper surface of the bottom plate 222 can also be provided with an insertion hole 222c and a groove 222b. The insertion hole 222c is The through hole penetrates the entire upper surface and the lower surface of the bottom plate 222 so that the insertion hole 222c communicates with the buffer cavity 224 and the accommodation cavity 223 at the same time. The groove 222 b is formed by a portion of the upper surface recessed downward toward the buffer cavity 224 by a certain depth, and the groove 222 b does not penetrate the lower surface of the bottom plate 222. At the same time, the groove 222b extends to the insertion hole 222c, so that the groove 222b communicates with the insertion hole 222c. The number of grooves 222b may be multiple, and the plurality of grooves 222b may be symmetrically distributed with respect to the insertion hole 222c. When the cigarette 20 is in contact with the upper surface of the bottom plate 222, the outside air entering the socket 222c can also enter the groove 222b. Therefore, the outside air can not only enter the cigarette 20 through the socket 222c, but also It enters into the cigarette 20 through the groove 222b, thereby increasing the contact area of the cigarette 20 with the outside air.

The shape of the cover 300 is adapted to the shape of the open cavity 120 of the upper cover 100. The space between the outer sleeve 210 and the inner tube 220 forms a receiving space. When installed, a part of the cover 300 can basically fill the entire receiving space. , That is, a part of the shield 300 is contained in the containing space. A mounting hole 310 is opened in the partition 300. The mounting hole 310 extends in the vertical direction. The shape of the mounting hole 310 matches the shape of the inner tube 220, that is, the mounting hole 310 may be a round hole. The tube 220 is inserted into the mounting hole 310, and the inner tube 220 and the mounting hole 310 can form a clearance fit relationship. Obviously, the entire shield 300 is arranged around the inner tube 220, and thus is arranged around the accommodating cavity 223. At the same time, the bottom wall of the mounting hole 310 abuts against the side cylinder 221 of the inner tube 220, so that the bottom wall of the mounting hole 310 functions as a cover for the lower opening of the buffer cavity 224, thereby sealing the buffer cavity 224 to form a buffer The channel 224a, obviously, the buffer channel 224a and the socket 222c are connected to each other. The cover 300 may be made of materials with good heat insulation performance.

The cover 300 is also provided with a through hole 320 extending in the vertical direction. The through hole 320 and the mounting hole 310 communicate with each other. The sealing member 400 is filled in the through hole 320, so that the sealing member 400 and the through hole 320 forms a tight-fitting relationship. The sealing member 400 may be a flexible silicone material. When the sealing element 400 is matched with the through hole 320, the sealing element 400 can have a good sealing effect on the mounting hole 310 and prevent the gas in the mounting hole 310 from leaking from the through hole 320.

The heating element 510 is generally in a sheet-like structure and is arranged vertically. The lower part of the heating element 510 is inserted in the sealing member 400, and the upper part of the heating element 510 passes through the buffer cavity 224 and the socket 222c of the bottom plate 222 in turn to be accommodated in the housing. In the cavity 223, the tip of the heating element 510 is sharp. The heating element 510 also includes a substrate and a heating film. The heating film is silk-screened or plated on the substrate. That is, the substrate can be used as a carrier for the heating film. The heating film can be made of a metal material with low electrical resistance and good thermal conductivity. The heating film is electrically connected to the power supply assembly 12, and when the power supply assembly 12 supplies power to the heating film, the heating film converts electrical energy into heat energy. The cigarette 20 can absorb the heat energy of the heating film to be atomized to form smoke.

4, 5, and 6 at the same time, the atomizer 11 may also include a fixing seat 520, the fixing seat 520 is located below the mounting hole 310, the base of the heating element 510 is inserted on the fixing seat 520, the heating element 510 The base body of can be connected to the power supply assembly 12 through conductive electrodes, so that the power supply assembly 12 is electrically connected to the heating element 510 through the conductive electrodes. The sealing element 400 can only be filled in the through hole 320 of the septum 300. Of course, in order to improve the installation stability of the sealing element 400 and the sealing performance of the mounting hole 310, the lower part of the sealing element 400 can be directly fixed on the fixing seat 520, To prevent the sealing member 400 from loosening in the through hole 320, it is ensured that the sealing member 400 and the through hole 320 always maintain a tightly fitted relationship.

The side cylinder 221 is also provided with a first air inlet 221a extending in the horizontal direction. The first air inlet 221a is located at one end of the side cylinder 221 close to the power supply assembly 12, and the first air inlet 221a is a through hole and penetrates in the radial direction. The entire side cylinder 221 makes the first air inlet 221a communicate with the buffer channel 224a. Due to the sealing effect of the seal 400, the gas in the buffer channel 224a cannot leak through the through hole 320. The outer sleeve 210 is provided with a second air inlet hole 211 at one end close to the power supply assembly 12, and the second air inlet hole 211 is horizontally arranged. The partition cover 300 is provided with a third air inlet hole 330, the third air inlet hole 330 is arranged at an end of the partition cover 300 close to the power supply assembly 12, and the third air inlet hole 330 communicates with the mounting hole 310 and is arranged horizontally. The upper cover 100 is provided with a fourth air inlet 110, the fourth air inlet 110 is provided at an end of the upper cover 100 close to the power supply assembly 12, the fourth air inlet 110 communicates with the outside world and the open cavity 120, and the fourth air inlet 110 The same level setting. Since the first air inlet 221a, the second air inlet 211, the third air inlet 330, and the fourth air inlet 110 are all close to the power supply assembly 12 and arranged horizontally, the first air inlet 221a and the second air inlet The hole 211, the third air inlet 330 and the fourth air inlet 110 will jointly form an air inlet passage 101, which is close to the power supply assembly 12 and arranged horizontally, so that the outside air from the atomizer 11 is close to the power supply One end of the component 12 enters the inside of the atomizer 11. Obviously, the intake passage 101 communicates with the outside world and the buffer passage 224a.

When the cigarette 20 is used for smoking, the cigarette 20 can be inserted from the opening 130 of the upper cover 100 down into the accommodating cavity 223 of the inner tube 220. Due to the sharp part of the tip of the heating element 510, the heating element 510 is inserted The inside of the cigarette 20. When the lower end of the cigarette 20 abuts the upper surface of the bottom plate 222, the cigarette 20 cannot continue to move downward relative to the inner tube 220, so that a part of the cigarette 20 is exposed outside the entire atomizer 11. At this time, the bottom plate 222 supports and restricts the cigarette 20, and the user can touch the part exposed outside the atomizer 11 to inhale. In the process of smoking, the heating element 510 generates heat to form an appropriate temperature. Since the heating element 510 is inserted in the cigarette 20, the cigarette 20 will quickly absorb the heat of the heating element 510 and reduce the heat loss as little as possible. The temperature generated by the heat does not cause the cigarette 20 to burn, thereby preventing the burning cigarette 20 from generating more harmful substances, but the temperature generated by the heating element 510 can effectively atomize the cigarette 20 to form smoke.

When the user inhales, the outside air enters the socket 222c through the air inlet channel 101 and the buffer channel 224a in sequence. A part of the gas entering the socket 222c enters the cigarette 20 from the middle part, and the other part of the gas entering the socket 222c flows into the groove In 222b, and then enter the inside of the cigarette 20 from the edge portion, the gas entering the inside of the cigarette 20 will carry smoke to be absorbed by the user.

Due to the partition cover 300, a part of the partition cover 300 is accommodated in the space between the outer sleeve 210 and the inner tube 220, and the partition cover 300 is located outside the accommodating cavity 223 and surrounds the inner tube 220. When the heating element 510 generates When heat is generated, the heat in the accommodating cavity 223 must be transferred to the upper cover 100 through the inner tube 220, the septum 300, and the outer sleeve 210 in sequence, and then transferred from the upper cover 100 to the outside. Since the inner tube 220, the partition 300, and the outer sleeve 210 absorb more heat, the heat transferred to the upper cover 100 is smaller, thereby ensuring that the outer surface of the upper cover 100 directly in contact with the outside generates a lower temperature. Prevent the user from touching the upper cover 100 which is too high in temperature to cause discomfort. At the same time, the heat directly transferred to the outside through the upper cover 100 is greatly reduced, so that a part of the heat is stored in the inner tube 220, the partition 300, and the outer sleeve 210, that is, the inner tube 220, the partition 300, and the outer sleeve 210 play a role. The heat preservation effect of the accommodating cavity 223 causes a certain temperature to exist in the accommodating cavity 223. When inhaled again, the cigarette 20 can absorb the residual heat in the accommodating cavity 223 and atomize rapidly, thereby improving the utilization rate of energy. Furthermore, the intake passage 101 is arranged close to the power supply assembly 12, so that the flow path of the outside air to the cigarette 20 through the intake passage 101, the buffer passage 224a and the insertion hole 222c is shorter, which can reduce the intake passage 101 and the buffer passage 224a. The possibility of clogging with the socket 222c also makes the structure design of the entire electrically heated aerosol forming device 10 simpler.

Second embodiment

Referring to Figures 7, 8 and 9 at the same time, the main differences between this second embodiment and the first embodiment are: the structure of the inner tube 220 and the position of the buffer channel 224a. For other similarities, please refer to the first embodiment. Relevant descriptions will not be repeated here.

Referring to FIGS. 8, 9 and 10, specifically, the inner tube 220 includes a side cylinder 221, a bottom plate 222 and a protrusion 230. The bottom plate 222 is connected to the lower end of the side cylinder 221 so that the bottom plate 222 seals the lower end opening of the cavity enclosed by the side cylinder 221, so that the cavity enclosed by the side cylinder 221 all forms an accommodation cavity 223. The bottom plate 222 is provided with a jack 222c. The jack 222c is a through hole and penetrates both the upper surface and the bottom surface of the bottom plate 222. The heating element 510 passes through the jack 222c and is located in the accommodating cavity 223. The protrusion 230 is connected to the upper surface of the bottom plate 222 and is located in the accommodating cavity 223, and the protrusion 230 protrudes a certain length relative to the bottom plate 222. Of course, the protrusion 230 may not be connected to the bottom plate 222, but directly connected to the side cylinder 221. In the case of inserting the cigarette 20 from the opening 130 of the upper cover 100 into the accommodating cavity 223 of the inner tube 220, when the lower end of the cigarette 20 abuts against the surface of the protrusion 230, the cigarette 20 will not be able to face each other The inner tube 220 continues to move downward, so that a part of the cigarette 20 is exposed outside the entire atomizer 11. At this time, the protrusion 230 supports and limits the cigarette 20. In addition, the cigarette 20 will seal the portion of the accommodating cavity 223 between the cigarette 20 and the bottom plate 222, thereby forming a buffer channel 224a. Obviously, the buffer channel 224a communicates with the socket 222c. When the inner tube 220 is inserted into the mounting hole 310 of the partition 300, the lower surface of the bottom plate 222 and the bottom wall of the mounting hole 310 are in close contact with each other, thereby eliminating the bottom wall and the bottom wall of the mounting hole 310 as in the first embodiment. The buffer channel 224a between the lower surfaces of the 222 (outside the first accommodating cavity 223) is provided with the protrusion 230 so that the buffer channel 224a in the second embodiment is located in the accommodating cavity 223.

The side cylinder 221 of the inner tube 220 is provided with a first air inlet hole 221a, and the first air inlet hole 221a may be a circular hole and extend in a horizontal direction. The first air inlet 221a and the buffer channel 224a communicate with each other. When the user inhales, the external air entering the first air inlet 221a enters the cigarette 20 through the buffer channel 224a in turn, instead of entering the cigarette 20 through the insertion hole 222c as in the first embodiment. After the external air enters the buffer channel 224a through the first air inlet 221a, the external air in the buffer channel 224a almost forms a contact relationship with the end surface of the cigarette 20, so that the external air and the cigarette 20 form a larger release area. , It is convenient for a sufficient amount of outside air to enter the inside of the cigarette 20 to carry the smoke. Since the outside air does not need to enter the cigarette 20 through the insertion hole 222c, the insertion hole 222c only serves to penetrate the heating element 510, and does not have the gas conduction function as in the first embodiment.

The positions of the second air inlet 211, the third air inlet 330, and the fourth air inlet 110 are the same as those of the first embodiment, that is, the first air inlet 221a, the second air inlet 211, and the third air inlet 330 The four of the fourth air inlets 110 form the air inlet channel 101. When the user inhales, outside air enters the cigarette 20 through the air inlet channel 101 and the buffer channel 224a to carry smoke.

Similarly, since the partition 300 is provided, a part of the partition 300 is accommodated in the space between the outer sleeve 210 and the inner tube 220. When the heating element 510 generates heat, the heat in the accommodating cavity 223 must pass through the inner tube in turn 220, the partition 300, and the outer sleeve 210 are transmitted to the upper cover 100, and then transmitted from the upper cover 100 to the outside. Since the inner tube 220, the partition 300, and the outer sleeve 210 absorb more heat, the heat transferred to the upper cover 100 is smaller, thereby ensuring that the outer surface of the upper cover 100 directly in contact with the outside generates a lower temperature. Prevent the user from touching the upper cover 100 which is too high in temperature to cause discomfort. At the same time, the heat directly transferred to the outside through the upper cover 100 is greatly reduced, so that a part of the heat is stored in the inner tube 220, the partition 300, and the outer sleeve 210, that is, the inner tube 220, the partition 300, and the outer sleeve 210 play a role. The heat preservation effect of the accommodating cavity 223 causes a certain temperature to exist in the accommodating cavity 223. When inhaled again, the cigarette 20 can absorb the residual heat in the accommodating cavity 223 and atomize rapidly, thereby improving the utilization rate of energy. Furthermore, the intake passage 101 is arranged close to the power assembly 12, so that the flow path of the external air directly to the cigarette 20 through the intake passage 101 and the buffer passage 224a is shorter, which can reduce the possibility of blockage of the intake passage 101 and the buffer passage 224a. , Which also makes the structure design of the entire electrically heated aerosol forming device 10 simpler.

The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, all possible combinations of the various technical features in the above-mentioned embodiments are not described. However, as long as there is no contradiction in the combination of these technical features, All should be considered as the scope of this specification.
