Description

Technical Field

[0001] This utility model relates to the field of atomization equipment technology, and in particular to an aerosol generation device. Background Technology

[0002] Electronic cigarettes are a fashionable product that has emerged with the advancement of science and technology and the improvement of people's living standards. They can help cigarette lovers relax, relieve stress, and better express their individuality. Playing with the casing of an electronic cigarette is also a kind of fun while smoking cigarettes. Therefore, electronic cigarette products are sought after by many users, especially young users.

[0003] Among existing e-cigarette products, there are those that heat liquid aerosol media (commonly known as e-liquid) and those that heat solid aerosol media (commonly known as tobacco). Users typically use these e-cigarettes by opening the cap, placing the cartridge or tobacco product into the heating chamber, and then inhaling to activate the heating process. However, some e-cigarettes do not effectively use the opening and closing of the cap to responsively indicate the user's intention to inhale vapor. In other words, opening and closing the cap does not activate or deactivate the heating process. This is somewhat lacking for fashion-conscious users, and such e-cigarettes are not perfect and fail to meet user requirements. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art.

[0005] Therefore, this utility model proposes an aerosol generating device. This utility model can effectively utilize the opening and closing of the cover to respond to the user's desire to inhale the smoke, thereby satisfying the user's requirements. It can also keep the cover in the open state to avoid accidental closing of the cover due to accidental touch, which would affect the user's use.

[0006] This application provides an aerosol generating device, including a housing, a cover, a switch feedback component, and a holding component. The housing has a cigarette inlet and a heating circuit inside. The cover is movably connected to the housing and can reciprocate between a first position and a second position. When the cover is in the first position, it blocks the cigarette inlet; when the cover is in the second position, the cigarette inlet is fully open. At least a portion of the switch feedback component is disposed on the housing, and the switch feedback component can detect the position of the cover and feed the detection result back to the heating circuit. The holding component is disposed on the housing and is in direct or indirect contact with the cover. The holding component can exert a force on the cover to maintain the cover in the second position.

[0007] As can be seen from the above technical solutions, the embodiments of this application have the following advantages:

[0008] The cover and housing are movably connected, and the cover can move back and forth between a first position and a second position. When the cover is in the first position, it blocks the cigarette inlet. The switch feedback component detects the position of the cover and sends feedback to the heating circuit, which then does not operate. This indicates that the user is not using the device to smoke. If the user opens the cover to the second position and inserts the tobacco product into the cigarette inlet, the switch feedback component detects the position of the cover and sends feedback to the heating circuit. The heating circuit then reacts accordingly and prepares to preheat the tobacco product. In this case, the device detects the user's intention to smoke based on the opening of the cover and simultaneously initiates the heating of the tobacco product. Furthermore, the device's holding component exerts force on the cover, keeping it in the second position and preventing accidental closure that could affect user operation.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] like Figures 1-9 As shown in the illustration, this application provides an aerosol generating device, including a housing 1, a cover 2, a switch feedback component 3, and a holding component 4. The housing 1 is provided with a cigarette inlet 11, and the interior of the housing 1 is provided with a heating chamber 16 and a heating circuit. The aerosol generating medium, such as some tobacco products, can be inserted into the heating chamber 16 through the cigarette inlet 11, with the filter part of the tobacco product remaining outside the housing 1. The heating circuit can heat the part of the tobacco product inserted into the heating chamber 16.

[0023] The cover 2 and the housing 1 are movably connected. The cover 2 can move back and forth between the first position W1 and the second position W2. When the cover 2 is in the first position W1, the cover 2 blocks the cigarette inlet 11. When the cover 2 is in the second position W2, the cigarette inlet 11 is fully open. At least part of the switch feedback component 3 is disposed on the housing 1. The switch feedback component 3 can detect the position of the cover 2 and feed the detection result back to the heating circuit. The holding component 4 is disposed on the housing 1 and is in direct or indirect contact with the cover 2. The holding component 4 can exert a force on the cover 2 to keep the cover 2 in the second position W2.

[0024] Based on the above technical solution, the cover 2 and the housing 1 are movably connected. The cover 2 can move back and forth between the first position W1 and the second position W2. When the cover 2 is in the first position W1, the cover 2 blocks the cigarette inlet 11. The switch feedback component 3 detects the position of the cover 2 and feeds it back to the heating circuit. The heating circuit does not work, indicating that the user is not using the device to smoke cigarettes. If the user opens the cover 2 to the second position W2 and inserts the tobacco product into the cigarette inlet 11, the switch feedback component 3 can detect the position of the cover 2 and feed it back to the heating circuit. The heating circuit reacts accordingly and prepares to preheat the tobacco product. In this case, the device knows that the user wants to smoke cigarettes based on the user opening the cover 2 and simultaneously promotes the heating of the tobacco product. Furthermore, the holding component 4 of the device can exert a force on the cover 2 to keep the cover 2 in the second position W2, preventing the cover 2 from closing due to accidental contact and affecting the user's use.

[0025] In some embodiments, the switch feedback component 3 includes a first reaction component 31 and a second reaction component 32. The first reaction component 31 and / or the second reaction component 32 are electrically connected to the heating circuit. The first reaction component 31 is disposed on the housing 1, and the second reaction component 32 is disposed on the cover 2. The second reaction component 32 can move with the cover 2 and change position with the first reaction component 31. The first reaction component 31 and / or the second reaction component 32 can respond to the heating circuit regarding the position of the cover 2.

[0026] During the process of the cover 2 moving from the first position W1 to the second position W2, or during the process of the cover 2 moving from the second position W2 to the first position W1, the distance between the first reaction component 31 and the second reaction component 32 changes linearly. That is to say, when the cover 2 is in the first position W1, the distance between the first reaction component 31 and the second reaction component 32 is at its maximum or minimum. Correspondingly, when the cover 2 is in the second position W2, the distance between the first reaction component 31 and the second reaction component 32 is at its minimum or maximum.

[0027] As a preferred embodiment, the switch feedback component 3 includes a Hall element 33 and a first magnetic element 34; wherein, the Hall element 33 is configured as a first reaction component 31 and the first magnetic element 34 is configured as a second reaction component 32, or, the Hall element 33 is configured as a second reaction component 32 and the first magnetic element 34 is configured as a first reaction component 31.

[0028] In some embodiments, a Hall element 33 is provided on the housing 1 near the cigarette inlet 11. The cigarette inlet 11 is generally the end of the housing 1, that is, the Hall element 33 is provided at the end of the housing 1. A tactile switch 64 and a linear motor 65 are provided in the middle of the housing 1. The tactile switch 64 and the linear motor 65 are both electrically connected to the heating circuit mentioned above. The Hall element 33 detects that the cover 2 is in the second position W2, and the cigarette inlet 11 is fully exposed. When the consumer clicks the tactile switch 64, the linear motor 65 vibrates, reminding the customer that the heating of the aerosol generating medium has begun.

[0029] As a preferred embodiment, an FPC board 6 and a heating module 5 are disposed inside the housing 1. The heating module 5 includes a bracket 51 and a heating element 52. The heating element 52 is provided with a heating circuit, and the heating method can be electromagnetic waves, lasers, thermal radiation, or other forms of energy. The FPC board 6 is connected to the bracket 51. The FPC board 6 has a first segment 61, a second segment 62, and a third segment 63. The first segment 61 of the FPC board 6 is connected to the bracket 51 at the end of the housing 1 corresponding to the first segment 61. A Hall element 33 is disposed on the first segment 61 of the FPC board 6. The second segment 62 of the FPC board 6 is located relative to its first segment. The second segment 62 of the FPC board 6 is bent and pressed against the bracket 51. The touch switch 64 is located at the end of the second segment 62 of the FPC board 6 away from its first segment 61. The third segment 63 of the FPC board 6 is bent relative to its second segment 62, bends into the interior of the bracket 51 and is pressed against the bracket 51. A linear motor 65 and a pressure sensor 66 are set in the third segment 63 of the FPC board 6. The pressure sensor 66 detects the pressure inside the housing 1. When a consumer takes a breath by holding the filter of the cigarette product in their mouth, the pressure inside the housing 1 will decrease. The pressure sensor 66 will detect the pressure change, and then the heating component 52 will heat the cigarette product.

[0030] In some embodiments, the switch feedback component 3 forms a detection area 35 around the cigarette inlet 11. The movement of the cover 2 may cover the detection area 35 or completely expose the detection area 35. The switch feedback component 3 can react to the position of the cover 2 based on whether the detection area 35 is covered or completely exposed.

[0031] The switch feedback component 3 can be selected from infrared sensors, induction switches or tactile switches 64, etc. When the cover 2 moves to the second position W2, it will trigger the infrared sensor, induction switch or tactile switch 64 and feed the result back to the heating circuit. The heating circuit will preheat the cigarette product inserted into the heating chamber 16 and officially start the heating program after the user puts the filter in his mouth and takes a breath.

[0032] The heating circuit can heat the aerosol generating medium inserted into the heating chamber 16. The aerosol generating medium includes components such as tobacco products that can generate aerosols through heating, ultrasound, or mechanical vibration. The aerosol generating medium can be an atomizing medium carrier loaded with liquid e-liquid. The e-liquid is a mixed liquid containing nicotine and alkaloids, and its solutes are common organic solutes and / or inorganic solutes such as propylene glycol, vegetable glycerin, and pure water. After being heated, the e-liquid disperses into tiny mixed droplets and mixes with air to form an aerosol. The aerosol generating medium can also be a leaf-based atomizing medium. After being heated, the leaf-based atomizing medium volatilizes tiny solid particles and mixes with air to form an aerosol.

[0033] This application can heat ordinary cigarettes, the filter of which is outside the housing 1, and there is a gap between the cigarette and the cigarette holder 11, through which air can enter the heating chamber 16. When the user holds the cigarette filter in his mouth and takes a breath, the heating circuit is triggered, and the heating circuit heats the cigarette.

[0034] However, as users move their arms, the cap of ordinary e-cigarette products will slide or swing, squeezing the cigarette and potentially causing it to shift position, resulting in incomplete heating of the tobacco. Furthermore, the cap of e-cigarette products cannot be fixed in the open position but will slide or swing with arm movements, which will also reduce the user's inhalation effect and affect the user's mood. Such e-cigarette products are still a drawback for users who pursue fashion.

[0035] Therefore, this application provides a retaining component 4 to keep the cover 2 in the open state.

[0036] In some embodiments, a magnetic force can be formed between the holding member 4 and the cover 2, and when the cover 2 is in the second position W2, the magnetic force can hold the cover 2 in the second position W2.

[0037] The cover 2 moves back and forth between the first position W1 and the second position W2, and the magnetic force will change accordingly, which can show a linear change.

[0038] A first magnetic element 34 can be provided on the cover 2, and a second magnetic element can be provided on the shell 1.

[0039] As a preferred embodiment, the first magnetic element 34 and the second magnetic element exhibit like poles repulsing each other. The second magnetic element can be positioned close to the cigarette holder 11. When the cover 2 is in the first position W1, the distance between the first magnetic element 34 and the second magnetic element is the closest, and the magnetic force is the greatest. The magnetic force pushes the cover 2 to move towards the second position W2.

[0040] As another preferred option, the first magnetic element 34 and the second magnetic element exhibit opposite attraction. The second magnetic element can be placed close to the second position W2. When the cover 2 is in the second position W2, the distance between the first magnetic element 34 and the second magnetic element is the closest, and the magnetic force is the greatest. The magnetic force is such that it pulls the cover 2 and prevents it from moving to the first position W1.

[0041] In some embodiments, the retaining component 4 includes an elastic element, the two ends of which are connected to the housing 1 and the cover 2 respectively. The elastic element can generate an elastic force on the cover 2. The elastic force is manifested as assisting the cover 2 to move from the first position W1 to the second position W2 and preventing the cover 2 from moving from the second position W2 to the first position W1. Therefore, the elastic force gradually decreases during the process of the cover 2 moving from the first position W1 to the second position W2.

[0042] As a preferred option, the elastic element can be a spring, a sheet, or an elastic cord, etc. If a spring is used, the spring can be set near the cigarette holder 11. However, whether the cover 2 is in the first position W1 or the second position W2, the spring is in a compressed state. Alternatively, the spring can be set near the second position W2. In this case, whether the cover 2 is in the first position W1 or the second position W2, the spring is in a stretched state.

[0043] The spring clips and elastic cords can also be configured accordingly, but the specific details will not be explained here.

[0044] In some embodiments, the cover 2 is slidably or rotatably disposed on the housing 1.

[0045] A cigarette holder 11 is provided on one end face of the housing 1, and a flange 12 is formed on this end face. When the cover 2 is in the first position W1, the flange 12 surrounds the cover 2, and when viewed from the front view of the housing 1, at least part of the cover 2 is covered by the flange 12. The cover 2 is partially or completely hidden, which is more aesthetically pleasing and reduces the chance of accidentally opening the cover 2.

[0046] In some embodiments, the cover 2 includes a first component 21 disposed inside the housing 1 and a second component 22 disposed on the end face of the housing 1. A first reaction component 31 may be disposed on the first component 21, and the second component 22 can extend into the cigarette inlet 11 and is detachably connected to the first component 21.

[0047] The housing 1 includes a body 15, a sandwich layer 13, and an end cap 14. The end cap 14 is disposed on the body 15 and has a cigarette inlet 11 and a groove 141. The sandwich layer 13 has a sliding groove 131 and a through hole 132 corresponding to the cigarette inlet 11. A first component 21 is connected to the sliding groove 131. The end cap 14 and the sandwich layer 13 are connected to cover the first component 21. A second component 22 is connected to the end cap 14. A portion of the second component 22 extends from the groove 141 into the interior of the end cap 14 and is detachably connected to the first component 21. A second reaction component 32 is disposed on the side of the end cap 14 away from the second component 22. The second reaction component 32 can be a detection component such as a Hall element 33.

[0048] As a preferred embodiment, the end cap 14 is provided with a first connecting part 142 and a first locking part 143, and a relief groove 133 is provided at a corresponding position on the interlayer 13. The first connecting part 142 and the first locking part 143 are detachably connected to the body 15 through the corresponding relief groove 133. Similarly, the interlayer 13 is provided with a second connecting part 134 and a second locking part 135, and the second connecting part 134 and the second locking part 135 are detachably connected to the body 15.

[0049] As a preferred embodiment, the first connecting portion 142 and / or the second connecting portion 134 includes a snap fastener, and the first locking portion 143 and / or the second locking portion 135 includes a locking hole.
