Referring to Figures 1 and 2, the electrically heated aerosol generating device 10 provided by the present invention is used to atomize an aerosol-generating substrate, which may be a cigarette 20 used in combination with the electrically heated aerosol generating device 10, and the cigarette 20 has basically the same structure as a daily cigarette. The electrically heated aerosol generating device 10 includes a power supply assembly 12 and an atomizer 11, the power supply assembly 12 supplies power to the atomizer 11, the atomizer 11 converts electrical energy into thermal energy, and the aerosol-generating substrate absorbs the heat and is atomized to form a haze.

1st embodiment With reference to FIG. 3, FIG. 4 and FIG. 5 at the same time, the atomizer 11 includes an upper cover 100, a storage member 200, a separate cover 300, a sealing member 400 and a heat generating component 510. The upper cover 100 can store the separate cover 300 and the storage member 200, and the upper cover 100 can be made of a material with excellent heat insulating performance. The upper cover 100 has a roughly cylindrical structure, and the cross section of the upper cover 100 has a roughly racetrack shape. The upper cover 100 surrounds an opening cavity 120 with one side open, and the upper cover 100 further has an opening 130 communicating with the opening cavity 120, and the cigarette 20 is disposed so as to be insertable into the opening 130. The upper cover 100 and the storage member 200 may be integrally formed, i.e., may be formed as one part. That is, the storage member 200 is formed by extending downward from the inner surface of the upper wall of the upper cover 100.

The housing member 200 includes an external sleeve 210 and an internal tube 220, which are connected to each other, and the housing member 200 can be manufactured from a material with excellent thermal insulation performance. The external sleeve 210 is a cylindrical structure having a shape roughly the same as that of the upper cover 100, and the external sleeve 210 is accommodated in the opening cavity 120 of the upper cover 100, and the internal tube 220 is accommodated in the external sleeve 210. The internal tube 220 includes a side tube 221 and a bottom plate 222. The side tube 221 surrounds a cylindrical cavity, and the bottom plate 222 is provided adjacent to the end of the side tube 221, and the bottom plate 222 is connected to the inner wall of the side tube 221 and is located in the cavity of the side tube 221. The bottom plate 222 divides the cavity surrounded by the side tube 221 into two parts, such as an upper part and a lower part, and the upper part of the cavity is formed into a storage cavity 223 and the lower part of the cavity is formed into a buffer cavity 224, and the storage cavity 223 is used to store the cigarettes 20.

When the cigarette 20 is located in the storage 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 may further include an insertion hole 222c and a groove 222b. The insertion hole 222c is a through hole that penetrates the entire upper and lower surfaces of the bottom plate 222, so that the buffer cavity 224 and the storage cavity 223 are simultaneously connected by the insertion hole 222c. The groove 222b is formed by recessing a part of the upper surface downward toward the buffer cavity 224 by a certain depth, and the groove 222b does not penetrate the lower surface of the bottom plate 222. At the same time, the groove 222b extends to the insertion hole 222c and communicates with the insertion hole 222c. The number of grooves 222b may be multiple, and the multiple grooves 222b may be distributed symmetrically 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 that enters the insertion hole 222c can also enter the groove 222b, so that the outside air can not only enter the cigarette 20 through the insertion hole 222c, but also through the groove 222b, thereby increasing the contact area between the cigarette 20 and the outside air.

The shape of the separation cover 300 is adapted to the shape of the opening cavity 120 of the upper cover 100, and the space between the outer sleeve 210 and the inner tube 220 forms an accommodation space. When installed, a part of the separation cover 300 can basically fill the entire accommodation space, that is, a part of the separation cover 300 is accommodated in the accommodation space. An installation hole 310 is installed in the separation cover 300, the installation hole 310 extends vertically, and the shape of the installation hole 310 is adapted to the shape of the inner tube 220, that is, the installation hole 310 may be a circular hole. When installed, the inner tube 220 of the accommodation member 200 is inserted and arranged in the installation hole 310, and the inner tube 220 and the installation hole 310 can form a clearance fit relationship. Obviously, the entire separation cover 300 is arranged to surround the inner tube 220 and to surround the accommodation cavity 223. At the same time, the bottom wall of the installation hole 310 abuts against the side tube 221 of the internal tube 220, functioning as a lid for the lower opening of the buffer cavity 224, sealing the buffer cavity 224 and forming a buffer passage 224a. Apparently, the buffer passage 224a and the insertion hole 222c are in communication with each other. The separation cover 300 can be manufactured from a material with excellent thermal insulation performance.

The separation cover 300 is further provided with a through hole 320, which extends vertically and communicates with the installation hole 310. The sealing member 400 is filled into the through hole 320, so that the sealing member 400 and the through hole 320 form a tight fit relationship. The sealing member 400 may be made of a soft silicone material. When the sealing member 400 and the through hole 320 are fitted together, the sealing member 400 can provide a good seal for the installation hole 310 and prevent the gas in the installation hole 310 from leaking out of the through hole 320.

The heating component 510 has a roughly sheet-like structure and is arranged vertically. The lower part of the heating component 510 is inserted into the sealing member 400, and the upper part of the heating component 510 passes through the buffer cavity 224 and the insertion hole 222c of the bottom plate 222 sequentially to be accommodated in the accommodation cavity 223, and the tip of the heating component 510 is sharp. The heating component 510 includes a substrate and a heating film, and the heating film is screen printed or plated on the substrate, that is, the substrate can be used as a carrier to support the heating film. The heating film can be made of a metal material with low resistance and excellent 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 thermal energy. The cigarette 20 can absorb the thermal energy of the heating film and be atomized to form smoke.

4, 5 and 6, the atomizer 11 may further include a fixing seat 520, which is located below the installation hole 310. The base of the heat generating component 510 is inserted into the fixing seat 520 and connected to the power assembly 12 through the conductive electrode, so that the power assembly 12 is electrically connected to the heat generating component 510 through the conductive electrode. The sealing member 400 may be filled only in the through hole 320 of the separation cover 300. Of course, in order to improve the installation stability of the sealing member 400 and the sealing performance for the installation hole 310, the lower part of the sealing member 400 may be directly fixed to the fixing seat 520 to prevent the sealing member 400 from loosening in the through hole 320 and ensure that the sealing member 400 and the through hole 320 are always tightly fitted.

The side cylinder 221 is further provided with a first intake hole 221a extending horizontally, which is located at one end of the side cylinder 221 close to the power assembly 12, and the first intake hole 221a is a through hole that penetrates the entire side cylinder 221 in the radial direction, thereby communicating with the buffer passage 224a. The gas in the buffer passage 224a cannot leak from the through hole 320 due to the sealing of the sealing member 400. A second intake hole 211 is provided at one end of the outer sleeve 210 close to the power assembly 12, and the second intake hole 211 is arranged horizontally. A third intake hole 330 is provided on the separation cover 300, which is arranged at one end of the separation cover 300 close to the power assembly 12, and the third intake hole 330 is connected to the installation hole 310 and arranged horizontally. The top cover 100 is provided with a fourth intake hole 110, which is disposed at one end of the top cover 100 close to the power assembly 12, and the fourth intake hole 110 communicates with the outside and the opening cavity 120, and is also disposed horizontally. The first intake hole 221a, the second intake hole 211, the third intake hole 330, and the fourth intake hole 110 are all disposed horizontally close to the power assembly 12, so that the first intake hole 221a, the second intake hole 211, the third intake hole 330, and the fourth intake hole 110 together form one intake passage 101, which is disposed horizontally close to the power assembly 12, so that outside air enters the inside of the atomizer 11 from one end of the atomizer 11 close to the power assembly 12. Apparently, the intake passage 101 connects the outside to the buffer passage 224a.

When the cigarette 20 is used for inhalation, the cigarette 20 can be inserted downward into the receiving cavity 223 of the inner tube 220 through the opening 130 of the upper cover 100. The heating element 510 is inserted into the cigarette 20 by the sharp tip of the heating element 510. When the lower end of the cigarette 20 abuts against the upper surface of the bottom plate 222, the cigarette 20 cannot continue to move downward relative to the inner tube 220, and a part of the cigarette 20 is exposed from the entire atomizer 11. At this time, the bottom plate 222 plays a role in supporting and limiting the position of the cigarette 20, and the user can smoke by touching the part exposed from the atomizer 11. During smoking, the heating element 510 generates heat to form an appropriate temperature, and since the heating element 510 is inserted and positioned in the cigarette 20, the cigarette 20 can quickly absorb the heat of the heating element 510 and reduce heat loss as much as possible. The temperature caused by the heat prevents the cigarette 20 from burning, and the burning cigarette 20 can prevent more harmful substances from being generated. However, the temperature generated by the heating element 510 allows the tobacco 20 to be effectively atomized to form smoke.

When the user inhales, outside air passes through the intake passage 101 and the buffer passage 224a in sequence and enters the insertion hole 222c, some of the gas that enters the insertion hole 222c enters the inside of the cigarette 20 from the middle part, another part of the gas that enters the insertion hole 222c flows into the groove 222b and further enters the inside of the cigarette 20 from the edge, and the gas that enters the inside of the cigarette 20 carries smoke and is absorbed by the user.

The separation cover 300 is arranged so that a part of the separation cover 300 is accommodated in the space between the outer sleeve 210 and the inner tube 220, and the separation cover 300 is arranged so as to be located outside the accommodation cavity 223 and surround the inner tube 220. Therefore, when the heat-generating component 510 generates heat, the heat in the accommodation cavity 223 must be transferred to the upper cover 100 through the inner tube 220, the separation cover 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 separation cover 300, and the outer sleeve 210 absorb more heat, less heat is transferred to the upper cover 100, and the temperature generated on the outer surface of the upper cover 100 that is in direct contact with the outside is lowered, which prevents the user from feeling uncomfortable when touching the overheated upper cover 100. At the same time, the heat directly transferred to the outside through the upper cover 100 is greatly reduced, and some of the heat is stored in the inner tube 220, the separation cover 300, and the outer sleeve 210, that is, the inner tube 220, the separation cover 300, and the outer sleeve 210 play a certain heat preservation role, so that a constant temperature exists in the receiving cavity 223. When inhaling again, the tobacco 20 absorbs the residual heat in the receiving cavity 223 and is quickly atomized, improving the energy utilization rate. In addition, the intake passage 101 is disposed close to the power supply assembly 12, so that the flow path of the outside air through the intake passage 101, the buffer passage 224a, and the insertion hole 222c to reach the tobacco 20 is shorter, the possibility of the intake passage 101, the buffer passage 224a, and the insertion hole 222c being blocked is reduced, and the structural design of the entire electrically heated aerosol generator 10 is also simpler.

Second Embodiment Referring to Figures 7, 8 and 9 simultaneously, the main difference between the second embodiment and the first embodiment is the structure of the inner tube 220 and the position of the buffer passage 224a. For other similarities, please refer to the relevant description of the first embodiment and will not be repeated here.

8, 9, and 10, specifically, the inner tube 220 includes a side tube 221, a bottom plate 222, and a protrusion 230. The bottom plate 222 is connected to the lower end of the side tube 221 and serves to seal the opening of the lower end of the cavity surrounded by the side tube 221, and the entire cavity surrounded by the side tube 221 forms the storage cavity 223. An insertion hole 222c is provided on the bottom plate 222, and the insertion hole 222c is a through hole that penetrates both the upper and lower surfaces of the bottom plate 222, and the heat generating component 510 passes through the insertion hole 222c and is located in the storage cavity 223. The protrusion 230 is connected to the upper surface of the bottom plate 222 and is located in the storage cavity 223, and the protrusion 230 protrudes from the bottom plate 222 by a certain length. Of course, the protrusion 230 may be directly connected to the side tube 221 without being connected to the bottom plate 222. When the cigarette 20 is inserted downward into the receiving cavity 223 of the inner tube 220 through the opening 130 of the upper cover 100, when the lower end of the cigarette 20 abuts against the surface of the protrusion 230, the cigarette 20 cannot continue to move downward relative to the inner tube 220, and a part of the cigarette 20 is exposed from the entire atomizer 11. At this time, the protrusion 230 plays a role of supporting and limiting the position of the cigarette 20. In addition, the cigarette 20 plays a role of sealing the part between the cigarette 20 and the bottom plate 222 of the receiving cavity 223, so that the buffer passage 224a is formed by the part. Obviously, the buffer passage 224a is connected to the insertion hole 222c. When the inner tube 220 is inserted into the installation hole 310 of the separation cover 300, the lower surface of the bottom plate 222 and the bottom wall of the installation hole 310 are in close contact with each other, so the buffer passage 224a (located outside the first accommodating cavity 223) located between the bottom wall of the installation hole 310 and the lower surface of the bottom plate 222 in the first embodiment is eliminated. In addition, by arranging the protrusion 230, the buffer passage 224a in the second embodiment is located inside the accommodating cavity 223.

A first intake hole 221a is provided on the side tube 221 of the inner tube 220, and the first intake hole 221a is a circular hole that can extend horizontally. The first intake hole 221a is connected to the buffer passage 224a. When the user inhales, the outside air that enters the first intake hole 221a enters the inside of the cigarette 20 through the buffer passage 224a in sequence, instead of entering the inside of the cigarette 20 through the insertion hole 222c as in the first embodiment. After the outside air enters the buffer passage 224a through the first intake hole 221a, the outside air in the buffer passage 224a forms a nearly complete contact relationship with the end surface of the cigarette 20, forming a larger contact area between the outside air and the cigarette 20, which is favorable for sufficient outside air to enter the inside of the cigarette 20 and carry smoke. Because outside air does not enter the cigarette 20 through the insertion hole 222c, the insertion hole 222c does not have a gas conduction function as in the first embodiment, and serves only as a place for the heat generating component 510 to pass through.

The positions of the second air intake hole 211, the third air intake hole 330, and the fourth air intake hole 110 are the same as in the first embodiment, that is, the first air intake hole 221a, the second air intake hole 211, the third air intake hole 330, and the fourth air intake hole 110 similarly form the air intake passage 101. When the user inhales, the outside air passes through the air intake passage 101 and the buffer passage 224a in sequence, enters the inside of the cigarette 20, and carries the smoke.

Similarly, since the separation cover 300 is disposed and a part of the separation cover 300 is accommodated in the space between the outer sleeve 210 and the inner tube 220, when the heat generating component 510 generates heat, the heat in the accommodation cavity 223 must be transferred to the upper cover 100 through the inner tube 220, the separation cover 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 separation cover 300, and the outer sleeve 210 absorb more heat, less heat is transferred to the upper cover 100, and the temperature generated on the outer surface of the upper cover 100 that is in direct contact with the outside is guaranteed to be lower, thereby preventing the user from feeling uncomfortable when touching the overheated upper cover 100. At the same time, the heat directly transferred to the outside through the upper cover 100 is greatly reduced, and some of the heat is stored in the inner tube 220, the separation cover 300, and the outer sleeve 210, that is, the inner tube 220, the separation cover 300, and the outer sleeve 210 play a certain heat preservation role, so that a constant temperature exists in the receiving cavity 223. When inhaling again, the tobacco 20 absorbs the residual heat in the receiving cavity 223 and is quickly atomized, improving the energy utilization rate. In addition, the intake passage 101 is arranged close to the power supply assembly 12, so that the flow path through which the outside air directly reaches the tobacco 20 through the intake passage 101 and the buffer passage 224a is shorter, the possibility of the intake passage 101 and the buffer passage 224a being blocked is reduced, and the structural design of the entire electrically heated aerosol generating device 10 is also simpler.

The technical features of the above-mentioned embodiments may be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, to the extent there is no contradiction between the combinations of these technical features, they should all be considered within the scope described in this specification.

The above examples only represent some embodiments of the present invention, and although the description is more specific and detailed, the description should not be understood as limiting the scope of the invention. It should be noted that a person skilled in the art can make some modifications and improvements without departing from the concept of the present invention, and all of these fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be as defined by the appended claims.
