Description

Technical Field

[0001] The present application relates to the field of aerosol generation technology, and in particular to a heat-not-burn device. Background Art

[0002] A heat-not-burn device is an appliance that heats and bakes aerosol-generating products to produce aerosols. Generally speaking, the use of aerosol-generating products is not a continuous process; puffing often involves pauses due to the user changing breaths, temporarily attending to other matters, and so on. During these pauses, the temperature of the heating element and the internal hot air gradually decreases as the pause increases. Therefore, when the user takes another puff, the heat-not-burn device requires more time to control the heating temperature to the preset level, resulting in a slower response to aerosol generation during the next puff.

DETAILED DESCRIPTION

[0050] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application.

In all examples shown and discussed here, any specific values should be interpreted as being merely exemplary, not as limitations. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following figures, and therefore, once an item is defined in one figure, it does not need to be further discussed in subsequent figures.

[0053] See also Figure 1-5 As shown, the present application provides a heat-without-combustion device 100, which includes an air flow channel 22. The air flow channel 22 includes an air inlet channel 221 and a heating chamber 222. The heating chamber 222 communicates with the air inlet channel 221. Ambient air flows from the air inlet channel 221 into the heating chamber 222, where it is heated to form a hot air flow. The hot air flow is used to heat and bake the aerosol-generating article 200 to generate an aerosol.

[0054] Furthermore, the heat-without-combustion device 100 further includes a partition 10. The partition 10 is used to control whether the heating chamber 222 is in communication with the outside.

[0055] Furthermore, the partition 10 has a first state and a second state. When a user takes a puff, the partition 10 is in the first state, and the heating chamber 222 is connected to the outside world through the air inlet channel 221. This allows air from the outside world to enter the heating chamber 222 through the air inlet channel 221, where it is heated to form the hot air flow, which in turn bakes the aerosol-generating substrate to generate aerosol.

[0056] During a pause in the user's puff, the partition 10 is in the second state, and the air inlet channel 221 is blocked, preventing the hot air flow within the heating chamber 222 from exchanging heat with the external air flow through the air inlet channel 221. This keeps the hot air flow within the heating chamber 222 in a heat-insulating state, preventing the hot air flow within the heating chamber 222 from rapidly cooling down. Consequently, when the user takes another puff, this portion of the hot air flow within the heating chamber 222 can be heated to a preset temperature more quickly, thereby baking the aerosol-generating article 200 to generate aerosol. This improves the response speed of the aerosol-generating article 200 to generate aerosol when the user takes another puff, thereby enhancing the user experience.

[0057] At the same time, the amount of heat required to heat the hot air flow in the heating chamber 222 to a preset temperature will also be reduced accordingly, thereby increasing the life of the heat-without-combustion device 100 and making the heat-without-combustion device 100 more energy-efficient.

[0058] Furthermore, in one embodiment, the separator 10 switches from the second state to the first state based on the negative pressure of suction, so that the separator 10 responds quickly to the negative pressure and does not need to be switched manually.

[0059] Furthermore, in the first embodiment, the partition 10 is a one-way valve. When the user takes a puff, the one-way valve is in the first state, so that the heating chamber 222 is connected to the outside through the air inlet channel 221, and the outside air can enter the heating chamber 222 through the air inlet channel 221 and be heated to the hot air flow.

[0060] During the pause period for inhalation, the one-way valve is in the second state, so that the heating chamber 222 is isolated from the outside, thereby achieving heat preservation of the hot air flow in the heating chamber 222 and preventing the hot air flow from cooling down quickly.

[0061] In a second embodiment, the separator 10 may also be a one-way bead disposed within the air inlet passage 221. Under the negative pressure generated by suction, the one-way bead overcomes gravity and moves within the air inlet passage 221, thereby connecting the air inlet passage 221 to the outside world. During periods of pause in suction, the one-way bead blocks the air inlet passage 221 due to gravity, isolating the heating chamber 222 from the outside world.

[0062] In other embodiments, the separator 10 may also be switched between the first state and the second state based on manual control. For example, the separator 10 may be a baffle that switches between the second state and the first state under the action of an external force such as pressing, pushing, pulling, or twisting.

[0063] Furthermore, the heat-not-burn device 100 further includes a housing and a heating assembly 30. The housing is structured to form a receiving chamber 21 and the airflow channel 22. The receiving chamber 21 is used to receive the aerosol-generating article 200. The heating assembly 30 is used to heat the airflow in the heating chamber 222 to form a hot airflow.

[0064] When the aerosol generating product 200 is inserted into the receiving chamber 21 and inhaled by the user, the hot air flow in the heating chamber 222 enters the aerosol generating product 200 to heat and bake the aerosol generating product 200, thereby causing the aerosol matrix in the aerosol generating product 200 to generate aerosol, which is mixed with the hot air flow and enters the user's mouth.

[0065] Furthermore, the heating component 30 is arranged in the heating chamber 222, and the heating component 30 has a heating channel 321 connecting the heating chamber 222 and the receiving bin 21. The external air flow flows through the air inlet channel 221, the heating chamber 222, the heating channel 321 and the receiving bin 21 in sequence, and is heated in the heating channel 321 to form a hot air flow.

[0066] Furthermore, the housing includes a main body 23 and a cover 24. The main body 23 is configured to have a receiving groove 211 and the heating chamber 222, with the heating channel 321 communicating between the receiving groove 211 and the heating chamber 222. The cover 24 is removably attached to the main body 23 and, together with the main body 23, forms the air inlet channel 221. When the cover 24 is open, at least a portion of the air inlet channel 221 is exposed, facilitating cleaning of this portion of the air inlet channel 221.

[0067] Furthermore, the cover body 24 is structured to form a receiving hole 212 , the receiving hole 212 is communicated with an end of the receiving groove 211 away from the heating channel 321 , and the receiving hole 212 and the receiving groove 211 together define the receiving compartment 21 .

[0068] By providing the receiving hole 212 on the cover 24 and the receiving groove 211 on the main body 23, it is convenient for the user to clean the receiving hole 212 and the receiving groove 211 when the cover 24 is opened.

[0069] Furthermore, the main body 23 includes a first shell 231, a first bracket 232, an inner shell assembly 233, a seal 234, and a first cover 235. The first shell 231 has a cavity 2311 and a first opening 2312. The first opening 2312 communicates with the cavity 2311 and is adjacent to the cover 24. The first cover 235 covers the first opening 2312. The first bracket 232, the inner shell assembly 233, and the seal 234 are each housed within the cavity 2311.

[0070] Furthermore, the first bracket 232 is received within the cavity 2311 and is configured to form a first accommodating compartment 2321. The opening of the first accommodating compartment 2321 is located adjacent to one side of the cover 24. The inner housing assembly 233 is disposed within the first accommodating compartment 2321 and is configured to form the receiving slot 211 and the heating chamber 222. The heating assembly 30 is disposed within the heating chamber 222.

[0071] See also Figure 6 As shown, the seal 234 is sealed between the inner shell and the cover body 24, and the seal 234 is structured to form a sealing hole 2341, which is connected between the receiving hole 212 and the receiving groove 211 and sealed on the peripheral side of the aerosol generating product 200 inserted into the receiving bin 21.

[0072] When the aerosol generating product 200 is inserted in the receiving bin 21 and the user does not inhale, the heating chamber 222 will form a relatively closed cavity under the cooperation of the partition 10 in the second state and the aerosol generating product 200 sealed and inserted in the receiving bin 21, thereby keeping the hot air flow in the heating chamber 222 in an insulation state.

[0073] Further, see Figure 7-11 As shown, the inner shell assembly 233 includes a support tube 2331, a second bracket 2332, and an end plate 2333. The support tube 2331 is disposed within the first accommodating chamber 2321. The second bracket 2332 is disposed within the support tube 2331. The end plate 2333 is sealingly connected to the end of the support tube 2331 away from the first cover plate 235, and together with the support tube 2331 and the second bracket 2332, defines the heating chamber 222.

[0074] Specifically, the support tube 2331 includes a first tube body 23311, a first open end 23312, and a second open end 23313. The first open end 23312 and the second open end 23313 are located at opposite ends of the first tube body 23311 along the direction in which the aerosol-generating article 200 is inserted into the receiving chamber 21. When the cover 24 is disposed on the main body 23, the seal 234 seals between the first open end 23312 and the cover 24.

[0075] See also Figure 12 As shown, the second bracket 2332 includes a second tube body 23321 and a partition 23322. The second tube body 23321 is connected to the first open end 23312 and extends into the first tube body 23311 toward the second open end 23313. The partition 23322 is disposed within the second tube body 23321 and separates the second tube body 23321 to form a mounting groove 23324 and the receiving groove 211. The receiving groove 211 is adjacent to the first open end 23312, and the mounting groove 23324 is adjacent to the second open end 23313. The heating assembly 30 is disposed within the mounting groove 23324, and the partition 23322 is provided with a through hole 23323 connecting the mounting groove 23324 and the receiving groove 211.

[0076] By providing the partition 23322 , the aerosol generating product 200 can be limited by the partition 23322 when inserted into the receiving chamber 21 , thereby preventing the aerosol generating product 200 from being over-inserted or under-inserted, thereby affecting the baking effect.

[0077] At the same time, the heating component 30 is formed with a plurality of heating channels 321. The hot air flows formed by heating in the plurality of heating channels 321 will converge in the through hole 23323 and enter the matrix segment evenly from the insertion end of the aerosol generating product 200, thereby evenly heating and baking the matrix segment.

[0078] Furthermore, the heating assembly 30 includes a heating element 31 and a heat exchange core 32. The heating element 31 covers the circumference of the heat exchange core 32, and the heating element 31 and the heat exchange core 32 are fixed in the mounting groove 23324 by a filling material 33 (such as ceramic glue or silicone). The heat exchange core 32 is structured to form the heating channel 321.

[0079] Furthermore, the end plate 2333 is sealedly connected to the second open end 23313. The end plate 2333 and the first tube body 23311 may be an integral structure or a split structure. When the end plate 2333 and the first tube body 23311 are split structures, a sealing ring 2334 is provided between the end plate 2333 and the first tube body 23311 to ensure that the end plate 2333 is sealedly connected to the second open end 23313.

[0080] Furthermore, the first open end 23312 includes an outer extension portion 233121 extending outward from the first tube body 23311, and an inner extension portion 233123 extending inward from the first tube body 23311. The outer extension portion 233121 is used to securely mount the support tube 2331 on the first bracket 232, and the inner extension portion 233123 is used to mount the seal 234 and the second bracket 2332.

[0081] Furthermore, the extension portion 233121 and the first bracket 232 can be fixedly connected by, but not limited to, welding, snapping, plugging, buckling, locking, etc.

[0082] Taking the locking method as an example, a first locking hole 2322 is provided on the first bracket 232, and the extension part 233121 is provided in a corresponding second locking hole 233122 corresponding to the first locking hole 2322, and the locking piece 239 passes through the second locking hole 233122 and is locked in the first locking hole 2322, so that the support tube 2331 is fixedly connected to the first bracket 232 and is located in the first accommodating compartment 2321.

[0083] Furthermore, the inner extension portion 233123 extends along the second open end 23313 and includes a first ring portion 233124 and a second ring portion 233125. The first ring portion 233124 is connected between the second ring portion 233125 and the outer extension portion 233121, and along the direction from the first open end 23312 to the second open end 23313, the second ring portion 233125 is close to the second open end 23313, and the first ring portion 233124 is between the first open end 23312 and the second ring portion 233125.

[0084] Furthermore, the first ring portion 233124 is used to install the seal 234 , and the second ring portion 233125 is used to install the second bracket 2332 .

[0085] Furthermore, the sealing member 234 includes a ring body 2342, an inner ring portion 2343, and an outer ring portion 2344. The inner ring portion 2343 is connected to the inner side of the ring body 2342 and is located near one end of the cover 24. The outer ring portion 2344 is connected to the outer side of the ring body 2342 and is located in the middle of the ring body 2342.

[0086] The ring body 2342 is sealed between the cover body 24 and the first ring portion 233124 along the direction of inserting the aerosol generating product 200 into the receiving chamber 21, the inner ring portion 2343 is constructed to form the sealing hole 2341, the outer ring portion 2344 is sealed and connected between the first opening end 23312 and the first cover plate 235, and the first cover plate 235 is limited to the outer peripheral side of the ring body 2342 corresponding to the inner ring portion 2343.

[0087] Furthermore, the air inlet passage 221 includes a first section 2211 and a second section 2212 that are interconnected. The first shell 231, the first cover plate 235, and the cover body 24 together form the first section 2211. The first cover plate 235, the sealing member 234, and the support tube 2331 together form the second section 2212.

[0088] The second section 2212 is connected between the first section 2211 and the heating chamber 222. The external airflow enters the airflow channel from the first section 2211, flows through the second section 2212 and enters the heating chamber 222, and is heated in the heating chamber 222 to form a hot airflow to enter the aerosol generating product 200.

[0089] Furthermore, the separation plate is a one-way valve plate, which is provided at the first opening end 23312 and is located at the communication port 223 between the second section 2212 and the heating chamber 222 .

[0090] Furthermore, the one-way valve disc is mounted on a side of the second ring portion 233125 close to the second open end 23313.

[0091] Furthermore, the first opening end 23312 extends toward the second opening end 23313 to form a limiting rib 23314 . The limiting rib 23314 is disposed around the outside of the communication port 223 , and the limiting rib 23314 is structured to form at least one limiting slot 23315 .

[0092] See also Figure 13 As shown, the one-way valve disc includes a valve seat 11, a disc body 12, and an elastic connecting portion 13. The elastic connecting portion 13 is connected between the disc body 12 and the valve seat 11, so that the disc body 12 is located in the center of the valve seat 11. The valve seat 11 is inserted into the limiting slot 23315 and elastically clamped on the limiting rib 23314. As a result, the one-way valve disc is installed through the cooperation of its own structure and the limiting rib 23314, eliminating the need for dedicated fixings for installation.

[0093] In some embodiments, the valve seat 11 includes a first clamping arm 111, a connecting arm 112, and a second clamping arm 113. The connecting arm 112 is connected between the first clamping arm 111 and the second clamping arm 113 and inserted into the limiting slot 23315, so that the first clamping arm 111 and the second clamping arm 113 are elastically clamped on opposite sides of the limiting rib 23314 along the radial direction of the communicating hole 23323.

[0094] In one embodiment, a plurality of the limiting slots 23315 are spaced apart on the limiting rib 23314, the first clamping arm 111 is arranged on the inner side of the limiting rib 23314, and a connecting arm 112 is provided on the first clamping arm 111 corresponding to each of the limiting slots 23315, and each of the connecting arms 112 is respectively connected to a second clamping arm 113.

[0095] For further information, please refer to Figure 2-5 As shown, the first bracket 232 and the first shell 231 are jointly constructed to form a second accommodating bin 236 and a third accommodating bin 2372212. The second accommodating bin 236 is located at an end of the first accommodating bin 2321 away from the cover body 24, and the third accommodating bin 2372212 is located on one side of the first accommodating bin 2321 or the second accommodating bin 236, or the third accommodating bin 2372212 is located on the same side of the first accommodating bin 2321 and the second accommodating bin 236.

[0096] The heat-not-burn device 100 also includes a power supply module 40 and a control module 50. The power supply module 40 is housed in the second compartment 236, and the control module 50 is housed in the third compartment 2372212. The control module 50 is electrically connected to the power supply module 40 and the heating assembly 30, respectively. The power supply module 40 is used to supply power to the control module 50 and the heating assembly 30.

[0097] Furthermore, the cover 24 is rotatably covered on the main body 23 along the rotation axis. The cover 24 can be rotatably connected to the main body 23 via a rotating shaft 25, so that the cover 24 has a covering position and an open position relative to the main body 23.

[0098] See also Figure 2 As shown, when the cover body 24 is in the covering position, the cover body 24 and the end surface of the ring body 2342 away from the second opening end 23313 are sealed and abutted, and the receiving hole 212 is connected to the receiving groove 211 to define the receiving compartment 21.

[0099] See also Figure 5 As shown, when the cover body 24 is in the open position, the cover body 24 is separated from the end surface of the ring body 2342, and the first section 2211 is exposed to facilitate cleaning of the first section 2211.

[0100] Furthermore, a first magnetic member is provided on the cover 24, and a second magnetic member 238 is provided on the main body 23. The first magnetic member and the second magnetic member 238 attract each other to magnetically connect the cover 24 to the housing, thereby making it easier for the cover 24 to be opened relative to the main body 23 or to be closed on the main body 23.

[0101] Furthermore, the cover body 24 includes a second shell 242 and a second cover plate 243. The second cover plate 243 is covered on the second shell 242 and forms a heat dissipation cavity 244 together with the second shell 242.

[0102] The second shell 242 is configured to define the first hole 2421, and the second cover plate 243 is configured to define the second hole 2432 and the heat dissipation hole 2431. The second hole 2432 communicates with the first hole 2421 to define the receiving hole 212. The heat dissipation hole 2431 connects the heat dissipation cavity 244 and the air inlet passage 221, and the heat dissipation cavity 244 connects to the receiving hole 212.

[0103] Furthermore, during the baking process of the aerosol generating product 200, suction will drive the hot air flow mixed with the aerosol to move toward the user's mouth, and when it flows through the area corresponding to the receiving hole 212 in the aerosol generating product 200, part of the heat will be dissipated into the heat dissipation cavity 244 through the corresponding aerosol generating product 200, so that the air flow entering from the first hole 2421 enters the heat dissipation cavity 244 as the user draws, and after absorbing the heat dissipated by the aerosol generating product 200 in the heat dissipation cavity 244, enters the air flow channel through the heat dissipation hole 2431, and moves to the heating cavity 222 to be heated to form the hot air flow.

[0104] Therefore, by providing the heat dissipation holes 2431 and the heat dissipation cavity 244 communicating between the receiving hole 212 and the air inlet channel 221 , the aerosol generating product 200 can be cooled while the absorbed heat can be recycled, thereby improving the heating efficiency.

[0105] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0106] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
