Description

Technical Field

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

[0002] At present, aerosol delivery devices can heat aerosol products (such as non-combustible tobacco products) at a relatively low temperature (such as 250°C to 500°C), thereby allowing the aerosol products to release aerosols with tobacco flavor without burning and deliver them to consumers, replacing the burning of tobacco products. In the prior art, after the aerosol delivery device heats the aerosol product to generate an aerosol, smoke such as the aerosol may run around in the aerosol device, and when encountering cold air, condensate is formed and adheres to and accumulates on electronic components such as the motherboard. This part of the condensate will corrode the electronic components, eventually causing damage to the electronic components and reducing the service life of the aerosol delivery device. Summary of the invention

[0003] The present invention provides an aerosol delivery device to solve the technical problems that aerosol and other smoke generated by aerosol delivery devices in the prior art may spread randomly, causing the aerosol to form condensate when cooled and then corrode and damage electronic components.

[0004] In view of the above technical problems, an embodiment of the present invention provides an aerosol delivery device, comprising: The housing is provided with an inlet for inserting the aerosol product; An isolation member is disposed inside the shell, and the isolation member has a hollow receiving cavity for receiving a portion of the aerosol generating product; An upper cover, located at the upper end of the insulating member and provided with an insertion port, wherein the aerosol generating product is sequentially inserted into the accommodating cavity through the inlet of the housing and the insertion port of the upper cover; A heating module, installed in the containing cavity, for heating the aerosol product to generate aerosol; Wherein, an air intake channel and a condensation storage tank are provided between the isolation member and the upper cover.

[0005] Furthermore, the upper cover has a bent portion, which is bent toward the lower end of the isolation member and partially sleeved on the upper end of the isolation member, for controlling the air intake direction of the air intake passage.

[0006] Further, the condensate storage tank includes a first condensate storage tank and a second condensate storage tank, and the first condensate storage tank and the second condensate storage tank are both arranged on the air flow path of the intake passage.

[0007] Furthermore, the first condensation storage groove is arranged on the inner wall surface of the upper end of the isolation member close to the aerosol product; the second condensation storage groove is arranged on the outer wall surface of the upper end of the isolation member away from the aerosol product.

[0008] Furthermore, the first condensation storage groove is arranged around the inner wall surface of the isolation member, and at least one vent hole is provided on the first condensation storage groove.

[0009] Furthermore, the second condensate storage groove is a convex edge extending outward, and the convex edge abuts against the curved portion to form an airflow path.

[0010] Furthermore, the curved portion is provided with a slot for airflow to pass through.

[0011] Furthermore, a base is provided in the shell, the base is sealed and installed on the lower end of the isolation member, and a third condensation storage tank is provided on the base.

[0012] Furthermore, a rotatably connected top cover is provided on the top of the shell, and the top cover is provided with an opening connected to an inlet for inserting the aerosol product, and a first airflow gap is formed at the position where the top cover is rotatably connected to the shell, and external air enters the accommodating cavity through the first airflow gap.

[0013] Furthermore, the aerosol delivery device also includes a power supply assembly installed in the shell and a power supply interface provided on the shell, wherein a second air flow gap is formed between the power supply interface and the shell, so that external air enters the accommodating cavity through the second air flow gap.

[0014] In the present invention, the heating module heats the aerosol product in the accommodating cavity to generate an aerosol. Part of these aerosols are inhaled by the user, and part of them can flow into the shell through the air inlet channel between the insulating member and the upper cover, and then reach the area for installing electronic components to form condensate attached to the electronic components. However, a condensation storage tank is provided between the insulating member and the upper cover in the present invention. When the aerosol flows through the condensation storage tank, the aerosol condenses to form condensate, and adheres to the condensate storage tank, and does not continue to flow to the installation area of ​​the electronic components through the air inlet channel. This design effectively reduces the adhesion of condensate to the electronic components, thereby reducing the risk of damage to the electronic components, and thereby improving the overall service life of the aerosol delivery device.

[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] like Figures 1 to 3 As shown, one embodiment of the present invention provides an aerosol delivery device, comprising: The housing 1 is provided with an inlet 101 for inserting an aerosol product.

[0021] The insulating member 2 is arranged inside the housing 1, and has a hollow accommodating cavity 3 to accommodate part of the aerosol generating product. Specifically, the insulating member 2 is arranged inside the housing 1 and forms an air inlet with the housing 1. The heat generated by the heating module 5 can be more concentrated in the insulating member 2, which can effectively reduce the loss of heat and realize the full utilization of heat energy.

[0022] The upper cover 4 is located at the upper end of the isolation member 2 and is provided with an insertion port 41. The aerosol generating product is inserted into the accommodating chamber 3 through the inlet 101 of the housing 1 and the insertion port 41 of the upper cover 4 in sequence; that is, a portion of the aerosol generating product is inserted into the accommodating chamber 3 through the inlet 101 and the insertion port 41, and a portion is located outside the accommodating member for the user to inhale. It can be understood that the upper cover 4 is installed at the upper end of the isolation member 2, and the connection between the two includes but is not limited to snap connection, interference connection, integral molding, bonding, etc., which are not limited here.

[0023] The heating module 5 is installed in the accommodating cavity 3 and is used to heat the aerosol product to generate aerosol; wherein, an air inlet channel 6 and a condensation storage tank 7 are provided between the insulating member 2 and the upper cover 4. It can be understood that the heating module 5 is arranged at a position opposite to the aerosol product, so as to facilitate heating the aerosol product. The heating module 5 can heat the gas entering the accommodating cavity 3, and the heated gas heats the aerosol product to generate aerosol for the user to inhale.

[0024] In one embodiment, a support member is disposed on the top of the heating module 5 , and the aerosol generating product is installed in the isolation member 2 through the support member.

[0025] In the present invention, the heating module 5 heats the aerosol product in the accommodating chamber 3 to generate an aerosol. Part of these aerosols are inhaled by the user, and part of them can flow into the area for installing electronic components in the shell 1 through the air inlet channel 6 between the insulating member 2 and the upper cover 4, thereby forming condensate attached to the electronic components. However, a condensation storage tank 7 is provided between the insulating member 2 and the upper cover 4 in the present invention. When the aerosol flows through the condensation storage tank 7, the aerosol condenses to form condensate, and adheres to the condensation storage tank 7, and does not continue to flow to the installation area of ​​the electronic components through the air inlet channel 6. This design effectively reduces the condensate attached to the electronic components, thereby reducing the risk of damage to the electronic components, and thereby improving the overall service life of the aerosol delivery device.

[0026] In one embodiment, if Figure 1 and Figure 3 As shown, the upper cover 4 has a bent portion 42, which is bent toward the lower end of the isolation member 2 and partially sleeved on the upper end of the isolation member 2 to control the air intake direction of the air intake channel 6. Figure 3 As shown, the upper end of the insulating member 2 is connected to the top of the housing 1 through the upper cover 4. The heating module 5 is arranged at the lower end of the insulating member 2. When the aerosol generating product is inserted into the accommodating cavity 3, the heating module 5 is located below the aerosol generating product.

[0027] Furthermore, the curved extension portion 42 is covered on the upper end of the insulating member 2, and the arrangement of the curved extension portion 42 can control the air intake direction of the air intake channel 6. Specifically, when the user inhales the aerosol generating product, such as Figure 1 The dotted arrow indicates that the air flow path in the air inlet channel 6 is as follows: the gas in the housing 1 first enters from bottom to top through the air inlet channel 6 between the curved portion 42 and the outer side wall of the upper end of the insulating member 2; then flows through the air inlet channel 6 between the top of the insulating member 2 and the upper cover 4; then flows out from the air inlet channel 6 on the inner side wall of the upper end of the insulating member 2 from top to bottom; and finally enters the heating module 5 from the lower end of the accommodating chamber 3 to be heated. The heated gas will flow upward to heat the aerosol product located above the heating module 5 to generate aerosol for the user to inhale.

[0028] Since the air inlet direction of the air inlet channel 6 is limited by the curved portion 42, if the aerosol is to flow out to the area in the housing 1 for mounting electronic components, the gas needs to flow in the reverse direction. In this process, the gas needs to carry the aerosol and first enter the air inlet channel 6 on the inner side wall of the upper end of the isolation member 2 from bottom to top, then flow through the air inlet channel 6 between the top of the isolation member 2 and the upper cover 4, and finally flow out from the air inlet channel 6 between the curved portion 42 and the outer side wall of the upper end of the isolation member 2 from top to bottom. Since the aerosol delivery device does not generate a reverse suction force, when the gas needs to change the airflow direction from bottom to top to top to bottom, it will encounter a large flow resistance, which reduces the flow speed of the aerosol, making it difficult for the aerosol to flow out from the air inlet channel 6 in the reverse direction, thereby reducing the damage of the aerosol to the electronic components.

[0029] In one embodiment, if Figure 1 and Figure 3 As shown, the condensation accumulation groove 7 includes a first condensation accumulation groove 71 and a second condensation accumulation groove 72, and the first condensation accumulation groove 71 and the second condensation accumulation groove 72 are both arranged on the air flow path of the air inlet channel 6. Such a design enables the first condensation accumulation groove 71 and the second condensation accumulation groove 72 in the air inlet channel 6 to effectively block the gas carrying aerosol and prevent it from flowing in the reverse direction in the air inlet channel 6. Therefore, the blocked aerosol will condense and adhere in the two condensation accumulation grooves, preventing the aerosol from continuing to overflow to the area of ​​the electronic components through the air channel 6, thereby reducing potential damage to the electronic components.

[0030] Specifically, the heating module heats the aerosol product in the accommodating chamber 3 to generate an aerosol. The user inhales a portion of the aerosol, and the uninhaled portion will drift to the air inlet channel 6. Here, the aerosol comes into contact with the newly entered cold air, causing the temperature to drop, so that the vapor component in the aerosol reaches the dew point temperature and forms condensate. These condensates eventually adhere to the first condensation storage tank 71 and / or the second condensation storage tank 72, preventing the condensate from flowing back to the electronic component area, reducing the risk of damage to the electronic components, and thereby improving the overall service life of the aerosol delivery device.

[0031] In one embodiment, if Figure 1 and Figure 3As shown, the first condensation storage groove 71 is arranged on the inner wall surface of the upper end of the isolation member 2 close to the aerosol product; the second condensation storage groove 72 is arranged on the outer wall surface of the upper end of the isolation member 2 away from the aerosol product. That is, in this embodiment, the first condensation storage groove 71 is arranged on the inner wall surface of the upper end of the isolation member 2 close to the aerosol product, so as to perform the first condensation storage on the aerosol entering the air inlet channel 6 from the bottom to the top from the accommodating cavity 3. The second condensation storage groove 72 is arranged on the outer wall surface of the upper end of the isolation member 2 away from the aerosol product, so as to perform the second condensation storage on the aerosol entering the air inlet channel 6 between the curved extension portion 42 and the outer wall of the upper end of the isolation member 2 from the top to the bottom. The above-mentioned arrangement of the first condensation storage groove 71 and the second condensation storage groove 72 can enhance the blocking effect on the aerosol carried in the gas.

[0032] In one embodiment, if Figure 3 As shown, a first condensation storage groove 71 is arranged around the inner wall of the isolation member 2, and at least one vent hole 8 is provided on the first condensation storage groove 71. In this embodiment, the first condensation storage groove 71 is arranged around the inner wall of the isolation member 2. When the gas in the accommodating cavity 3 enters the first condensation storage groove 71 through the vent hole 8, the first condensation storage groove 71 will block and collect the part of the aerosol, that is, the part of the aerosol will condense and adhere to the first condensation storage groove 71, and will not continue to flow in the opposite direction through the air inlet channel 6.

[0033] In one embodiment, if Figure 3 As shown, the second condensate accumulation groove 72 is a convex edge extending outward, and the convex edge abuts against the curved extension portion 42 to form an airflow path. In this embodiment, the second condensate accumulation groove 72 is a convex edge arranged on the outer side of the upper end of the isolation member 2 and extending outward, and the convex edge abuts against the curved extension portion 42 to form an airflow path between the outer side of the isolation member 2 and the curved extension portion 42.

[0034] In some embodiments, the curved portion 42 is provided with a slot (not shown) for airflow to pass through. Specifically, when the upper cover 4 is mounted on the insulating member 2, the curved portion 42 partially abuts against the convex edge of the second condensation storage tank 72. At this time, the outside world enters the accommodating chamber 3 through the slot provided by the curved portion 42. Such a design not only ensures the circulation of airflow, but also cooperates with the structure of the second condensation storage tank 72 to control the path and distribution of the airflow.

[0035] Since the first condensation storage tank 71 is arranged on the inner side of the upper end of the isolation member 2, when the gas carrying the aerosol passes through the first condensation storage tank 71 to reach the second condensation storage tank 72, the reverse flow path of the gas needs to be changed by a larger angle (360 degrees), which will reduce the flow speed of the aerosol, so that the aerosol can be better condensed and stored in the second condensation storage tank 72, reducing the effect of condensation reflux to the electronic component area.

[0036] In one embodiment, if Figure 3 As shown, a base 9 is assembled inside the shell 1, and the base 9 is sealed and installed at the lower end of the isolation member 2, and a third condensation storage tank 107 is provided on the base 9. The connection method between the base 9 and the isolation member 2 includes but is not limited to snap-on, interference connection, one-piece molding, bonding, etc., and the specific method is not limited. The third condensation storage tank 107 is arranged in the connecting gap between the base 9 and the inner side wall of the isolation member 2 to collect the condensate formed after the aerosol condenses at this position, and prevent the aerosol from escaping from the connecting gap between the base 9 and the inner side wall of the isolation member 2. It is understandable that a seal can also be provided between the base 9 and the isolation member 2 to prevent smoke from leaking from the installation gap between the two.

[0037] It is understandable that the shape of the third condensation storage tank 107 can be set according to needs, including but not limited to an annular groove, etc. In other embodiments, the third condensation storage tank 107 can be arranged on the end surface of the base 9 facing the accommodating chamber 3, and arranged around the bottom of the heating module 5. Specifically, the heating module heats the aerosol product in the accommodating chamber 3 to generate an aerosol. When the user stops inhaling, the aerosol that has not been completely inhaled will drift into the air inlet channel 6 and the cavity of the isolation member 2. The aerosol condensate that drifts to the air inlet channel 6 eventually adheres to the first condensation storage tank 71 and / or the second condensation storage tank 72. As the temperature of the aerosol in the cavity of the isolation member 2 decreases, it will adhere to the inner wall of the isolation member 2 and flow into the third condensation storage tank 107, thereby collecting the condensate to prevent damage to the electronic components of the aerosol delivery device.

[0038] In one embodiment, if Figure 1 As shown, a rotatably connected top cover 11 is provided on the top of the housing 1, and the top cover 11 is provided with an opening 111 connected to the inlet 101 for inserting the aerosol product. The position where the top cover 11 is rotatably connected to the housing 1 forms a first airflow gap 12, and the outside air enters the accommodating chamber 3 through the first airflow gap 12. In this embodiment, as Figure 1 The dashed arrow in the middle indicates that the outside air can pass through the first air flow gap 12 between the top of the shell 1 and the top cover 11, then enter the air inlet channel, and finally enter the accommodating chamber 3 without setting up additional air inlet holes, which simplifies the processing technology of the aerosol delivery device and saves costs.

[0039] In one embodiment, if Figure 1 As shown, the aerosol delivery device further includes a power supply assembly 13 installed in the housing 1 and a power supply interface 14 provided on the housing 1, wherein a second airflow gap 15 is formed between the power supply interface 14 and the housing 1, so that the outside air passes through the second airflow gap 15, then enters the air inlet channel 6, and finally enters the accommodating chamber 3. In this embodiment, since the power supply interface 14 is an essential component of the aerosol delivery device, as shown in FIG. Figure 1The middle dotted arrow indicates that the outside air enters the accommodating chamber 3 from the second air flow gap 15 formed between the power interface 14 and the shell 1, which also avoids the need to provide an additional air inlet hole on the shell 1, simplifies the processing technology of the aerosol delivery device, and saves costs.

[0040] In one embodiment, if Figure 1 As shown, the aerosol delivery device comprises a first air flow gap 12 and a second air flow gap 15 .

[0041] The above are merely embodiments of the aerosol delivery device of the present invention and are not intended to limit the present invention.
