DETAILED DESCRIPTION

[0027] The application will be further described in details through specific embodiments in conjunction with the accompanying drawings. In different embodiments, similar elements are denoted by similar reference numerals. In the following embodiments, many details are described in order to make the application better understood. However, one skilled in the art can easily recognize that some features can be omitted in different cases, or can be replaced by other elements, materials, methods. In some cases, some operations related to the application are not shown or described in the specification in order to avoid the core part of the application being overwhelmed by too much description, and it is not necessary to describe these related operations in detail for one skilled in the art according to the description in the specification and general technical knowledge in the art.

[0028] In addition, the features described in the specification, operations or characteristics can be combined in any appropriate manner to form various embodiments, and the steps involved in each embodiment can be sequentially adjusted or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the description and drawings are only for the purpose of clearly describing one embodiment, and do not mean the necessary composition and / or order.

[0029] The serial numbers of the components described herein, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any sequential or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connections (couplings) unless otherwise specified.

[0030] As used herein, "aerosol" refers to a dispersion of solid or liquid particles in a gas. As used herein, "aerosol" can be used to refer to a substance that has been vaporized, atomized, in the form of a spray or jet, or otherwise converted from a solid or liquid form to an inhalable form comprising suspended solid or liquid drug particles. Aerosol-generating articles comprise a plurality of substances capable of forming aerosols assembled within a packaging material, which are well known in the art and include, but are not limited to: polyhydric alcohols such as triethylene glycol, 1,3-butanediol and glycerol; esters of polyhydric alcohols such as glycerol mono-, di- or triacetate; and aliphatic esters of mono-, di- or polybasic carboxylic acids such as dimethyl dodecanedioate and dimethyl tetradecanedioate.

[0031] In the present application, the heat-not-burn device uses the heat-not-burn principle to heat the aerosol-generating article C to form an aerosol. The heat-not-burn device includes a device main body 2 and a power supply assembly 3, the device main body 2 completes the main task of the heat-not-burn device, such as containing and heating the aerosol-generating article C, therefore, the device main body 2 includes a heating assembly 24 capable of generating heat to provide heat, and the power supply assembly 3 can supply power and work control to the heating assembly 24, the power supply assembly 3 includes an electrically connected battery 31 and a control circuit board 32, the battery 31 supplies power to the heating assembly 24 and the control circuit board 32, and the control circuit board 32 can respond to user commands, such as starting the heating assembly 24 or closing the heating assembly 24, adjusting the working power of the heating assembly 24, etc.

[0032] In order to facilitate the realization of the user's puff detection, realize the counting statistics of the puff number when the user puffs or complete the self-starting setting of the puff, the heating non-combustion device is provided with a sensing component 23, which can be triggered in the negative pressure state when the user puffs to sense the fluctuation of airflow or the change of air pressure. Based on this characteristic, the sensing component 23 should be placed in a closed space, which is isolated from the cavity where the aerosol generating article C is placed. When the user puffs, the space where the sensing component 23 is located will fluctuate due to the change of volume, and a pressure difference will be formed between the space and the cavity where the aerosol generating article C is placed. However, the closed space will produce a positive pressure when the sensing component 23 is assembled. When the user puffs, if the negative pressure produced is too small to balance the positive pressure, or if the negative pressure left after balancing the positive pressure is too small, the sensing component 23 cannot be triggered, thereby affecting the realization of the puff detection function, reducing the puff detection sensitivity of the sensing component 23, or in order to make the sensing component 23 be triggered, the user needs to puff with greater intensity and faster speed, thereby increasing the difficulty of the user's puff and affecting the user's puff experience.

[0033] The application creatively provides a pressure relief cavity on the device body 2, so that the device body 2 has a standby state and a use state. The standby state is a state in which the device body 2 has not been assembled and cannot be put into use. The use state is a state in which the device body 2 has been assembled and can be normally put into use.

[0034] Please refer to Figures 1 to 6, the device body 2 is provided with a containing cavity 21, the containing cavity 21 is provided with an elastic diaphragm 22, the elastic diaphragm 22 separates the containing cavity 21 into a first cavity 211 and a second cavity 212 isolated from each other, the first cavity 211 is used for accommodating the aerosol generating article C, the second cavity 212 is used for accommodating the sensing assembly 23, the cavity wall of the first cavity 211 is provided with a gas outlet 2111, the first cavity 211 is communicated with the outside through the gas outlet 2111, and the gas outlet 2111 can be used for inserting the aerosol generating article C into the first cavity 211, the cavity wall of the second cavity 212 is provided with a pressure relief hole 2121, in the preparation state, the second cavity 212 is communicated with the outside through the pressure relief hole 2121, when the sensing assembly 23 is installed, since the second cavity 212 is communicated with the outside through the pressure relief hole 2121, the gas pressure in the second cavity 212 is always consistent with the gas pressure of the outside, and positive pressure cannot be generated (when the volume of the closed space is reduced, the increase of pressure intensity will generate positive pressure in the closed space, the application creatively communicates the closed space with the outside, so that the positive pressure generated when the volume is reduced can be avoided); after the device body 2 and other structures of the heating non-combustion device are assembled, the device body 2 is switched to the use state, in the use state, the second cavity 212 is isolated from the outside, when the gas in the first cavity 211 is extracted through the gas outlet 2111, negative pressure is generated in the first cavity 211, so that pressure difference is generated between the second cavity 212 and the first cavity 211, that is, pressure difference is generated on both sides of the elastic diaphragm 22, at least part of the structure of the elastic diaphragm 22 is deformed under the action of negative pressure and towards the first cavity 211, so that part of the airflow in the second cavity 212 flows into the space generated by the deformation of the elastic diaphragm 22, and the gas in the second cavity 212 flows and generates negative pressure (the volume of the closed space increases, the pressure intensity decreases to generate negative pressure), the sensing assembly 23 is triggered to detect airflow fluctuation or pressure difference under negative pressure, so that the suction detection is completed.

[0035] Please refer to Figure 4The second cavity 212 includes a mounting cavity 2122 and a deformation cavity 2123, the mounting cavity 2122 and the deformation cavity 2123 are communicated through a sensing hole 2124, the sensing assembly 23 is arranged in the mounting cavity 2122, a sensing surface of the sensing assembly 23 is arranged towards the sensing hole 2124, a pressure relief hole 2121 is formed on a cavity wall of the deformation cavity 2123, and the elastic diaphragm 22 is arranged between the deformation cavity 2123 and the first cavity 211. Through the arrangement of the mounting cavity 2122 and the deformation cavity 2123, the sensing assembly 23 can be arranged away from the elastic diaphragm 22, so as to avoid that the elastic diaphragm 22 affects the detection accuracy of the sensing assembly 23 in the deformation process. In this embodiment, the mounting cavity 2122, the deformation cavity 2123 and the pressure relief hole 2121 are sequentially communicated. In the preparation state, when the sensing assembly 23 is mounted in the mounting cavity 2122, the sensing assembly 23 squeezes the gas in the mounting cavity 2122 to the deformation cavity 2123, and the deformation cavity 2123 discharges the gas to the outside through the pressure relief hole 2121, so that the gas pressure in the mounting cavity 2122 and the deformation cavity 2123 is consistent with the outside, that is, the atmospheric pressure is maintained. After the filling and sealing structure 2611 is filled, the mounting cavity 2122 and the deformation cavity 2123 are arranged in a sealed manner, and the gas capacity in the inside no longer changes. When the user sucks, the gas in the first cavity 211 is discharged to the outside from the gas outlet 2111, a negative pressure is generated in the first cavity 211, and there is a pressure difference between the negative pressure and the atmospheric pressure in the deformation cavity 2123, so that the elastic diaphragm 22 is deformed towards the first cavity 211, the space capable of accommodating gas in the deformation cavity 2123 becomes larger, part of the airflow flows into the increased space, so that the sensing surface of the sensing assembly 23 detects the airflow fluctuation or the pressure difference generated by the volume increase and pressure decrease of the deformation cavity 2123 and the mounting cavity 2122, thereby triggering the sensing assembly 23. The sensing assembly 23 can be an airflow sensor or a pressure sensor.

[0036] Please refer to Figure 4 and Figure 5 In some embodiments, the device body 2 includes a heating assembly 24, a heating assembly support 25 and a first sealing member 26, the first sealing member 26 is arranged between the heating assembly 24 and the heating assembly support 25, the mounting cavity 2122 and the pressure relief hole 2121 are formed on the first sealing member 26, and the deformation cavity 2123 is formed between the heating assembly support 25 and the first sealing member 26. In this embodiment, the elastic diaphragm 22 can be arranged on the first sealing member 26 and integrated with the first sealing member 26, and the first sealing member 26 is inserted into the heating assembly support 25, so that the elastic diaphragm 22, the first sealing member 26 and the heating assembly support 25 form the deformation cavity 2123. The heating assembly support 25 is used to support the heating assembly 24, the first sealing member 26 and the elastic diaphragm 22 can be made of silica gel material, and the first sealing member 26 can also realize the sealing between the heating assembly 24 and the heating assembly support 25.

[0037] Of course, in some other embodiments, the mounting cavity 2122 and the pressure relief hole 2121 can also be formed on the heat generating component support 25.

[0038] Referring to Figure 6 , the device body 2 further comprises a second sealing member 27, which is arranged between the heat generating component support 25 and the first sealing member 26 to form a deformation cavity 2123 between the first sealing member 26 and the second sealing member 27.

[0039] In order to realize the switching from the preparation state to the use state, the pressure relief hole 2121 needs to be plugged after the installation of each part. Since the existing heating non-combustion device requires miniaturized design, the internal space is small, the pressure relief hole 2121 is arranged on the cavity wall of the deformation cavity 2123, and directly plugging the pressure relief hole 2121 may affect the deformation cavity 2123, and ultimately affect the suction detection. In order to solve this problem, the first sealing member 26 is provided with a pressure relief channel 261, and the pressure relief hole 2121 is communicated with the outside through the pressure relief channel 261. In the use state, the pressure relief channel 261 is provided with a sealing structure 2611 for blocking the communication between the pressure relief hole 2121 and the outside, so as to form a closed deformation cavity 2123 and a mounting cavity 2122, so that the user can generate negative pressure to trigger the sensing component 23 during the later suction. The sealing structure 2611 can include a sealing plug or sealing glue filled in the pressure relief hole 2121.

[0040] Referring to Figure 4 , the heat generating component 24 comprises a power supply wire 242 and a heat generating element 241, and the power supply wire 242 can realize the electrical connection between the heat generating element 241 and the power supply component 3. The first sealing member 26 is provided with a wire inlet channel 262, one end of the power supply wire 242 passes through the wire inlet channel 262 and is electrically connected with the heat generating element 241, and the other end is electrically connected with the power supply component 3. There is an included angle between the axis of the wire inlet channel 262 and the axis of the pressure relief channel 261, which is conducive to fully utilizing the space in the device body 2 and facilitating the miniaturized design of the heating non-combustion device. The arrangement of the wire inlet channel 262 is conducive to the regular arrangement of the power supply wire 242, avoiding messy lines. Since there is an included angle between the axis of the wire inlet channel 262 and the axis of the pressure relief channel 261, that is, there is an overlapping space between the wire inlet channel 262 and the pressure relief channel 261, the sealing glue can be used to plug the pressure relief channel 261 while fixing the power supply wire 242. The included angle between the axis of the wire inlet channel 262 and the axis of the pressure relief channel 261 can be any acute angle, which can guide the power supply wire 242 from the power supply component 3 to the heat generating element 241.

Part of the structure of the base 245 is arranged between the inner tube 244 and the outer tube 243, so as to block the one end of the inner tube 244 and the outer tube 243 close to the heating assembly support 25. The base 245 and the first sealing member 26 enclose the airflow space 247. The first air inlet channel 246 is formed between the inner tube 244 and the outer tube 243. The base 245 is provided with a plurality of airflow holes 2451. One end of the first air inlet channel 246 is communicated with the outside through the air outlet 2111. The other end of the first air inlet channel 246 is communicated with the first cavity 211 through the airflow space 247 and the airflow holes 2451 in sequence. When a user sucks, the gas can enter the first cavity 211 through the air outlet 2111, the first air inlet channel 246, the airflow space 247 and the airflow holes 2451 in sequence, and carry the aerosol out through the air outlet 2111. The other end of the heating element 241 abuts against the inner tube 244, so that the heating element 241 is clamped between the base 245 and the inner tube 244. The heating element 241 can generate heat by itself or in a magnetic field after being powered on. When the heating element 241 generates heat by itself, the heating element 241 can include a tube body and a heating layer, a heating mesh, a heating film or a heating circuit arranged on the tube body, or can be directly made of a conductive heating material.

[0042] In some specific embodiments, the airflow holes 2451 are straight-through structures along the axis X direction of the first cavity 211, which can reduce the suction resistance of the user's suction and improve the user's use experience.

[0043] In some embodiments, the device body 2 further comprises a third sealing member 28. The first sealing member 26 is arranged on the side of the heating assembly 24 away from the heating assembly support 25.

The device body 2 and the power supply assembly 3 are arranged in the shell 1, and the power supply assembly 3 is arranged on the side of the heating assembly support 25 away from the heating assembly 24, so that the power supply assembly 3 is arranged away from the heating source to avoid affecting the normal work of the power supply assembly 3 due to high temperature. The suction nozzle support 4 is connected with the shell 1 in a snap-fit manner. The third sealing member 28 is arranged between the heating assembly 24 and the suction nozzle support 4, and is used for sealing the space between the suction nozzle support 4 and the heating assembly 24.

The clamping member 29 is used for clamping and fixing the aerosol generating article C, and a plurality of clamping protrusions 291 are arranged in the clamping member 29. An air inlet structure 292 is formed between two adjacent clamping protrusions 291, which communicates the air outlet 2111 and the second air inlet channel 281. The clamping protrusion 291 abuts against the outer wall of the aerosol generating article C, so that the aerosol generating article C can be centrally installed, and the gas at the circumference of the aerosol generating article C can be uniformly inhaled.
