Description

Technical Field

[0001] The present invention relates to the technical field of aerosol generation, and in particular to an electronic aerosol generating device. Background Art

[0002] At present, electronic aerosol generating devices can heat aerosol products (such as non-combustible tobacco products) at a relatively low temperature (such as 250°C to 500°C), thereby releasing aerosols with tobacco flavor to consumers without burning the aerosol products. Usually, there are electronic aerosol generating devices that start the heating function through a mechanical switch. The disadvantage of the above scheme is that the mechanical switch must be installed with a corresponding moving structure, which will result in poor sealing performance of the mechanical switch and cannot completely isolate the smoke, so that the smoke can enter the position where the electronic components are installed through the mechanical switch position. Then, after the smoke combines with the cold air, it will condense and adhere to the mechanical switch and other electronic components, and corrode them, eventually causing the mechanical switch to fail or the electronic components to be damaged, greatly reducing the life of the electronic aerosol generating device. Summary of the invention

[0003] In order to overcome the problem in the prior art that the mechanical switch self-starting scheme of the electronic aerosol generating device easily causes corrosion of the mechanical switch and other electronic components, thereby reducing the life span, the present invention provides an electronic aerosol generating device.

[0004] In view of the above technical problems, an embodiment of the present invention provides an electronic aerosol generating device, comprising: A support having a middle cavity for inserting and accommodating the aerosol generating product; A heating module, installed in the intermediate cavity, for heating the aerosol generating product and generating aerosol; The housing is provided with a mounting cavity for mounting electronic components; the bracket is mounted in the housing and is used to isolate the intermediate cavity from the mounting cavity; A non-contact sensor is mounted on the bracket and maintains a preset spacing distance from the aerosol generating product; the non-contact sensor is used to sense the action of inserting or removing the aerosol generating product from the intermediate cavity.

[0005] Furthermore, the electronic aerosol generating device also includes a first seal and a second seal; the first seal and the second seal respectively seal the opposite ends of the bracket, and the first seal, the second seal and the bracket together form the intermediate cavity.

[0006] Furthermore, the bracket includes an outer tube and an inner tube, the inner tube is installed in the outer tube; the inner tube is provided with an insertion cavity for plugging the aerosol generating product, and the non-contact sensor is embedded in the inner tube.

[0007] Further, the second sealing member is sealingly installed at an end of the outer tube away from the insertion cavity, and the first sealing member is sealingly installed between the inner tube and an end of the outer tube close to the insertion cavity.

[0008] Furthermore, the first sealing member is provided with a first air inlet, the space between the inner tube and the outer tube constitutes an air inlet cavity, and the first air inlet, the air inlet cavity and the insertion cavity are interconnected.

[0009] Furthermore, the shell also includes a first mounting member, which is arranged at one end of the inner tube close to the first sealing member to form an aerosol generating product insertion port.

[0010] Furthermore, the bracket is also provided with a containing tube, one end of which is in contact with the inner tube, and the other end of which is embedded in the second sealing member, and the heating module is installed in the containing tube.

[0011] Furthermore, a second air inlet is provided on the containing tube, and the first air inlet, the air inlet cavity, the insertion cavity and the second air inlet are interconnected.

[0012] Furthermore, a second mounting piece is provided in the bracket, and the heating module is fixedly installed in the accommodating tube through the second mounting piece. The second mounting piece is provided with a through hole communicating with the insertion cavity.

[0013] Furthermore, the non-contact sensor includes a plurality of infrared sensing elements, and the plurality of infrared sensing elements are respectively located on opposite sides of the aerosol generating article.

[0014] In the electronic aerosol generating device of the present invention, the bracket isolates the intermediate cavity for installing the aerosol generating product and the installation cavity for installing the electronic components. Therefore, after the heating module heats the aerosol product and generates hot melt adhesive, the smoke will be contained in the intermediate cavity and cannot escape from the intermediate cavity into the installation cavity to corrode and damage other electronic components, thereby ensuring the life of the non-contact sensor and other electronic components, and thus improving the life of the entire electronic aerosol generating device. At the same time, in the present invention, the non-contact sensor is installed in the intermediate cavity, and a preset spacing distance is maintained between the non-contact sensor and the aerosol generating product. The non-contact sensor performs non-contact sensing on the insertion or removal of the aerosol generating product in the intermediate cavity, avoiding direct contact between the non-contact sensor and the aerosol generating product, thereby preventing the aerosol generating product from being damaged by high temperature and physical contact such as friction and wear. This not only improves the measurement accuracy, but also ensures the long-term stability of the non-contact sensor. In addition, the non-contact sensor can quickly detect the plugging and unplugging of aerosol generating products, realizing a fast switching response of the electronic aerosol generating device. Its high response speed significantly improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] In the description of the present invention, it should be understood that the terms "longitudinal", "radial", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1 to Figure 2 As shown, an embodiment of the present invention provides an electronic aerosol generating device, comprising: The support 14 is provided with a middle cavity 11 for inserting and accommodating the aerosol generating product 30. The shape of the middle cavity 11 can be set according to the requirements, including but not limited to a cylindrical shape, a special-shaped cylindrical shape, etc.

[0023] The heating module 13 is installed in the middle cavity 11 and is used to heat the aerosol generating product 30 to generate aerosol. The heating module 13 is composed of a heat conductive part and a heating part arranged thereon. The heating part is responsible for heating the heat conductive part, thereby indirectly heating the gas flowing through the heat conductive part. The heated gas is then used to heat the aerosol generating product 30 to generate aerosol. The above-mentioned gas flow paths are all limited in the middle cavity 11, which prevents smoke from entering the installation cavity 12 to damage other electronic components.

[0024] The housing 10 is provided with a mounting cavity 12 for mounting electronic components. The bracket 14 is installed in the housing 10 and is used to isolate the intermediate cavity 11 from the mounting cavity 12 .

[0025] The non-contact sensor 20 is mounted on the bracket 14 and maintains a preset spacing distance from the aerosol generating product 30; the non-contact sensor 20 is used to sense whether the aerosol generating product 30 is located in the cavity 11 to start the heating element to enter the working state. It can be understood that the non-contact sensor 20 may include but is not limited to an infrared sensing element, a light sensing element, etc., which is a sensing element that can sense the insertion or removal of the aerosol generating product 30 in the middle cavity 11 without contacting the aerosol generating product 30.

[0026] In the electronic aerosol generating device of the above embodiment of the present invention, the bracket 14 isolates the intermediate cavity 11 for installing the aerosol generating product 30 and the installation cavity 12 for installing electronic components. Therefore, after the heating module 13 heats the aerosol product 30 and produces hot melt adhesive, the smoke will be contained in the intermediate cavity 11 and cannot escape from the intermediate cavity 11 into the installation cavity 12, thereby avoiding corrosion of other electronic components in the installation cavity 12, extending the service life of the non-contact sensor 20 and other electronic components, and thereby improving the life of the entire electronic aerosol generating device.

[0027] Furthermore, a mounting hole is provided on the bracket 14, and the non-contact sensor 20 can be riveted or bonded in the mounting hole to improve the sealing of the connection between the non-contact sensor 20 and the mounting hole. The shapes of the non-contact sensor 20 and the mounting hole are not limited, but are set so that a sealed assembly can be achieved between the two. In this embodiment, the non-contact sensor 20 is sealed and installed in the mounting hole, and the hole is blocked. This design ensures that the aerosol in the intermediate cavity 11 cannot enter the mounting cavity 12 through the mounting hole, thereby avoiding corrosion of other electronic components in the mounting cavity 12. This protective measure extends the service life of the non-contact sensor 20 and other electronic components, thereby improving the life of the entire electronic aerosol generating device. It is understandable that a mounting groove can also be provided on the bracket 14 to install the above-mentioned non-contact sensor 20.

[0028] In the present invention, the non-contact sensor 20 is installed in the middle cavity 11, and a preset spacing distance is set between the non-contact sensor 20 and the aerosol generating product 30 installed in the middle cavity 11. In other words, the sensor 20 does not contact the aerosol generating product 30, and the gap between them is about less than 1 mm. Since the non-contact sensor 20 avoids direct contact with the aerosol generating product 30, the aerosol generating product 30 is prevented from being damaged by high temperature and physical contact such as friction and wear, which not only improves the measurement accuracy, but also ensures the long-term stability of the non-contact sensor 20. In addition, the non-contact sensor 20 can quickly detect the plugging and unplugging actions of the aerosol generating product 30, realize the rapid switching response of the electronic aerosol generating device, and its high response speed significantly improves the user experience.

[0029] In one embodiment, if Figure 1 to Figure 2 As shown, the electronic aerosol generating device of the housing 10 further includes a first seal 15 and a second seal 16. The first seal 15 and the second seal 16 respectively seal the opposite ends of the bracket 14. The first seal 15, the second seal 16 and the bracket 14 together form an intermediate cavity 11. Figure 2 As shown, the bracket 14 is used to isolate the middle cavity 11 from the installation cavity 12. The first seal 15 is used to seal the top opening and the installation gap of the bracket 14, and the second seal 16 is used to seal the bottom opening and the installation gap of the bracket 14 to prevent the aerosol in the middle cavity 11 from entering the installation cavity 12 through the opening of the bracket 14 and the installation gap, thereby avoiding the smoke from running around. It can be understood that the material of the first seal 15 and the second seal 16 can be selected as needed, for example, the material of the first seal 15 and the second seal 16 can be made of a heat-resistant and elastic material, including but not limited to materials such as silicone.

[0030] In one embodiment, if Figure 2As shown, the bracket 14 includes an outer tube 141 and an inner tube 142, and the inner tube 142 is installed in the outer tube 141. The inner tube 142 is provided with an insertion cavity 1421 for plugging the aerosol generating product 30. The non-contact sensor 20 is embedded in the inner tube 142. Further, the non-contact sensor 20 includes a plurality of infrared sensing elements, and the plurality of infrared sensing elements are respectively located on opposite sides of the aerosol generating product 30. Specifically, the non-contact sensor 20 can be an infrared sensing element, and the infrared sensing element includes an infrared transmitter 201 and an infrared receiver 202. The infrared transmitter 201 and the infrared receiver 202 are respectively installed on the opposite side walls of the inner tube 142. The infrared transmitter 201 emits infrared light of a specific frequency, and the infrared light will directly reach the infrared receiver 202 without being blocked by the aerosol generating product 30, and generate a stable electrical signal to indicate that the electronic aerosol generating device does not need to enter the working state. In this embodiment, the inner tube 142 extends from the insertion port 1441 of the aerosol generating product 30 to the inside, and the insertion port 1441 is connected to the insertion cavity 1421. Specifically, the non-contact sensor 20 is arranged on the inner tube 142 to more accurately detect the insertion or removal of the aerosol generating product 30. More specifically, the non-contact sensor 20 is installed in a position close to the insertion port 1441 of the aerosol generating product 30 on the electronic aerosol generating device. When the user just inserts the aerosol generating product 30 into the inner tube 142, the non-contact sensor 20 detects it and activates the device to enter the working state.

[0031] In one embodiment, if Figure 1 and Figure 2 As shown, the second sealing member 16 is sealingly installed at one end of the outer tube 141 away from the insertion cavity 1421, and the first sealing member 15 is sealingly installed between the inner tube 142 and one end of the outer tube 141 close to the insertion cavity 1421. Figure 1 In the illustrated embodiment, the first seal 15 is disposed at the top of the outer tube 141 and the inner tube 142, and the first seal 15 is sealed and connected between the outer tube 141 and the inner tube 142. In this embodiment, both ends of the outer tube 141 are sealed and connected to the first seal 15 and the second seal 16 respectively, and the top of the inner tube 142 is sealed and connected to the first seal 15. In a specific embodiment, the inner tube 142 is integrally connected to the outer tube 141, and the inner tube 142 is partially connected to the side wall of the outer tube 142. The first seal 15 is used to seal the opening and installation gap between the top of the outer tube 141 and the inner tube 142, and the second seal 16 is used to seal the bottom opening and installation gap of the outer tube 141, so as to prevent the aerosol in the intermediate cavity 11 from entering the installation cavity 12 through the openings and installation gap at the top and bottom of the outer tube 141 and the inner tube 142, thereby avoiding the smoke from running around.

[0032] In one embodiment, if Figure 1 and Figure 2 As shown, the first sealing member is provided with a first air inlet 151. The space between the inner tube 142 and the outer tube 141 forms an air inlet cavity 143, and the first air inlet 151, the air inlet cavity 143 and the insertion cavity 1421 are interconnected. In this embodiment, the aerosol generating article 30 is inserted into the insertion cavity 1421 of the inner tube 142. Figure 1 As shown, the heating module 13 is mounted on the inner tube 142 and is located between the air inlet cavity 143 and the insertion cavity 1421. The gas will enter the air inlet cavity 143 from the first air inlet 151 located between the outer tube 141 and the inner tube 142, and then enter the insertion cavity 1421 after being heated by the heating module 13, and then heat the aerosol generating article 30 and generate aerosol. The above-mentioned gas flow path is limited only to the middle cavity 11, which prevents smoke from entering the installation cavity 12 to damage other electronic components.

[0033] In one embodiment, if Figure 2 As shown, the housing 10 further includes a first mounting member 144, which is disposed at one end of the inner tube 142 near the first sealing member 15 to form an aerosol generating product insertion port 1441. It can be understood that the insertion cavity 1421 is connected to the insertion port 1441, and the two are coaxially arranged. When the aerosol generating product 30 is inserted into the insertion cavity 1421 through the insertion port 1441, the inner side wall of the insertion port 1441 is in contact with the outer side wall of the aerosol generating product 30. Figure 2 As shown, the insertion port 1441 is located at the top of the insertion cavity 1421. Therefore, before the aerosol generating product 30 is inserted into the insertion cavity 1421, it will first pass through the insertion port 1441. It can be understood that the inner diameter of the insertion port 1441 is designed to match the outer diameter of the aerosol generating product 30, and can be slightly larger than or equal to the outer diameter of the aerosol generating product 30. At the same time, the inner diameter of the insertion port 1441 is smaller than the inner diameter of the insertion cavity 1421. Such a design ensures that when the aerosol generating product 30 is inserted into the insertion port 1441, it will be limited by the insertion port 1441 to prevent shaking, and ensure that the aerosol generating product 30 can be stably inserted into place. In addition, after the aerosol generating product 30 passes through the insertion port 1441 and enters the insertion cavity 1421, a certain gap is retained between its outer side wall and the inner side wall of the insertion cavity 1421, which allows the non-contact sensor 20 installed on the inner tube 142 to maintain a preset spacing distance with the aerosol generating product 30, thereby realizing non-contact sensing.

[0034] In one embodiment, the inner diameter of the insertion port 1441 is equal to the inner diameter of the insertion cavity 1421. This design allows the outer wall of the aerosol generating product 30 to fit closely with the inner wall of the insertion cavity 1421, further ensuring that the aerosol generating product 30 can be smoothly inserted into place.

[0035] In one embodiment, if Figure 1 to Figure 2As shown, the first mounting member 144 is annular, and the annular first mounting member 144 is sleeved on the inner tube 142, and the outer side wall of the first mounting member 144 is connected to the first sealing member 15. In this embodiment, the first mounting member 144 is sleeved on the inner tube 142, and the outer side wall is connected to the first sealing member 15, which ensures a stable connection between the first mounting member 144 and the inner tube 142, and also prevents smoke such as aerosol from entering the mounting cavity 12 from the connection position between the inner tube 142 and the first mounting member 144.

[0036] In one embodiment, if Figure 1 to Figure 2 As shown, the first mounting member 144 is provided with a first guide portion 1442, which is disposed at one end of the insertion port 1441 away from the insertion cavity 1421. The first guide portion 1442 can guide the aerosol generating product 30 to be smoothly inserted into the insertion port 1441 without being damaged. The first guide portion 1442 includes but is not limited to an inclined surface or a curved surface disposed at the insertion port 1441.

[0037] In one embodiment, if Figure 1 to Figure 2 As shown, the bracket 14 is further provided with a housing tube 146, one end of which is in contact with the inner tube 142, and the other end is embedded in the second sealing member 16, and the heating module 13 is installed in the housing tube 146. Specifically, the heating module 13 is installed in the housing tube 146, and the housing tube 146 wraps the heating module 13, which can reduce the amount of heat generated by the heating module 13 transferred to the outside, thereby achieving a stable heat preservation and heat storage function, while ensuring rapid heating of the aerosol generating product 30, it also ensures uniform and constant enhancement of heat energy, thereby ensuring the stability of the device and the consistency of suction.

[0038] In one embodiment, if Figure 1 to Figure 2 As shown, the bracket 14 is further provided with a second mounting member 145, and the heating module 13 is fixedly mounted in the accommodating tube 146 through the second mounting member 145. The second mounting member 145 is provided with a through hole 1451 communicating with the insertion cavity 1421. It can be understood that the through hole 1451 is connected to the insertion cavity 1421, and the two are coaxially arranged.

[0039] In one embodiment, if Figure 1 and Figure 2 As shown, the housing tube 146 is provided with a second air inlet 1461, and the first air inlet 151, the air inlet cavity 143, the insertion cavity 1421, the through hole 1451 and the second air inlet 1461 are interconnected. In this embodiment, when the aerosol generating product 30 is inserted, the non-contact sensor 20 detects the insertion action of the aerosol generating product 30 and then starts the electronic aerosol generating device. Figure 1As indicated by the arrow, when the user inhales, outside air enters from the insertion port of the aerosol generating product 30, flows into the air inlet cavity 143 through the first air inlet 151, and then enters the containing tube 146 from the second air inlet 1461, wherein the heating module 13 heats the air that flows through the intermediate cavity 11 and enters the heating module 13, and the heated air can only enter the insertion cavity 1421 through the through hole 1461 to bake the aerosol generating product 30, thereby generating an aerosol for the user to inhale, but cannot escape from the intermediate cavity 11 into the mounting cavity 12, thereby avoiding corrosion to other electronic components in the mounting cavity 12, extending the service life of the non-contact sensor 20 and other electronic components, and thereby improving the service life of the entire electronic aerosol generating device.

[0040] In one embodiment, if Figure 1 to Figure 2 As shown, a second guide portion 1462 is provided at one end of the receiving tube 146 close to the insertion cavity 1421. Figure 1 As shown, the second guide portion 1462 guides the aerosol generating product 30 from the insertion cavity 1421 through the upper end of the housing tube 146 to be inserted into the through hole 1451. The second guide portion 1462 may be in the form of an inclined surface or an arc surface disposed at the end of the housing tube 146 near the insertion cavity 1421, but is not limited thereto. The second guide portion 1462 may guide the aerosol generating product 30 to be smoothly inserted from the insertion cavity 1421 into the through hole 1451 to avoid damage during the insertion process.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
