[0035] Figure 1 It is a structural schematic diagram of an aerosol generating device provided in an embodiment of the present application. Figure 2 Schematic diagram of the decomposition structure of an aerosol generating device provided in an embodiment of the present application. Figure 1 and Figure 2 As shown, the aerosol generating device includes a housing 100 , a liquid storage tank 200 , a flexible circuit board 300 and an antenna 400 , and the liquid storage tank 200 is located in the housing 100 .

[0036] Figure 3 is a structural diagram of an aerosol generating device provided in an embodiment of the present application, Figure 3 At least a portion of the housing 100 is omitted. Figure 3As shown, there is a gap 100a between at least one side of the liquid storage tank 200 and the inner wall of the housing 100. The flexible circuit board 300 is located in the gap 100a and arranged opposite to the surface of the housing 100. The antenna 400 is formed on the flexible circuit board 300.

[0037] A gap is provided between the liquid reservoir 200 and the housing 100 of the aerosol generating device, which allows the flexible circuit board 300 to be positioned within the gap. The liquid reservoir 200 is the bulkiest structure in the aerosol generating device, possessing a large surface area. This gap allows for the placement of a relatively large flexible circuit board 300. The thinness of the flexible circuit board 300 also minimizes the impact on the volume of the aerosol generating device. The antenna 400 is formed on the flexible circuit board 300, utilizing its larger surface area to accommodate a larger antenna 400. This increases the size of the antenna 400 and improves the communication quality of the aerosol generating device.

[0038] In some examples, the flexible circuit board 300 can be adhered to the surface of the liquid storage tank 200 .

[0039] The liquid reservoir 200 contains a cavity for storing the aerosol matrix. To accommodate the aerosol matrix, the liquid reservoir 200 is typically the larger structure in the aerosol generating device, providing a relatively large and smooth outer surface. Laying the flexible printed circuit board 300 to the surface of the liquid reservoir 200 provides support for the flexible printed circuit board 300, maintaining a flat and stable installation.

[0040] For example, the flexible circuit board 300 may be bonded to the surface of the liquid storage tank 200 , so that the flexible circuit board 300 is fixed by an adhesive to prevent the flexible circuit board 300 from shaking.

[0041] Figure 4 This is a schematic diagram of the structure of a liquid storage tank provided in an embodiment of the present application. Figure 4 As shown, the liquid storage tank 200 includes a first side wall 201 and two second side walls 202 adjacent to the first side wall 201. The first side wall 201 and the second side wall 202 are connected in an arc. The flexible circuit board 300 is attached to the first side wall 201 and the second side wall 202.

[0042] Because the adjacent side walls of the liquid storage tank 200 are connected by arcs, resulting in a smooth surface transition, a portion of the flexible circuit board 300 can be attached to the second side wall 202 adjacent to the first side wall 201. This allows the flexible circuit board 300 to be bent smoothly without damage. Since the second side wall 202 adjacent to the first side wall 201 can be fully utilized for the flexible circuit board 300, it is convenient to arrange a larger area of ​​the flexible circuit board 300, allowing the antenna 400 to be larger in size, further improving communication quality.

[0043] Figure 5 This is a schematic diagram of the structure of a flexible circuit board provided in an embodiment of the present application. Figure 5 As shown, the aerosol generating device further includes an electronic device 311 . The electronic device 311 is located in the center of the flexible circuit board 300 , and the antennas 400 are distributed around the electronic device 311 .

[0044] The flexible circuit board 300 has a large area, and simply placing the antenna 400 may not fully utilize the area of ​​the flexible circuit board 300. By placing the electronic device 311 on the flexible circuit board 300, further utilization of the space within the flexible circuit board 300 is achieved. The strength of the signal radiated by the antenna 400 and its ability to receive signals are both directly proportional to the area enclosed by the antenna 400. Placing the electronic device 311 in the center of the flexible circuit board 300 and using the edge area of ​​the flexible circuit board 300 for the antenna 400, the antenna 400 is arranged around the electronic device 311, thereby enclosing a larger area. This improves the antenna 400's signal radiation and reception capabilities, further enhancing communication quality.

[0045] like Figure 5 As shown, the antenna 400 includes a plurality of polygonal patterns 401 , each of which surrounds the electronic device 311 .

[0046] As an example, the polygonal pattern 401 may be a rectangular pattern.

[0047] The polygonal pattern 401 may be a metal pattern etched on the flexible circuit board 300. Multiple polygonal patterns 401 are arranged around the electronic device 311, and the multiple polygonal patterns 401 together constitute the antenna 400, which can enhance the signal radiation and signal reception capabilities of the antenna 400.

[0048] By adjusting the number of polygonal patterns 401 , the signal radiation capability and signal reception capability of the antenna 400 can be adjusted, so that the antenna 400 can meet the communication requirements of the corresponding aerosol generating device. As an example, the antenna 400 can include five polygonal patterns 401 .

[0049] In some examples, the plurality of polygonal patterns 401 may be similar graphics.

[0050] In some examples, the electronic device 311 includes at least one of a Bluetooth chip and a near-field communication chip, and the antenna 400 is connected to the electronic device 311 .

[0051] Illustratively, the Bluetooth chip is connected to the antenna 400 to form a Bluetooth antenna module, thereby realizing the Bluetooth communication function.

[0052] Exemplarily, the near field communication chip is connected to the antenna 400 to form a near field communication antenna module, thereby realizing the near field communication function.

[0053] The specific structure included in the electronic device 311 can be set according to the communication method to be implemented, and the embodiments of the present application are not limited thereto.

[0054] Reference Figure 2 As shown, the housing 100 includes a first housing 110 and a second housing 120 that interlock. For example, the first housing 110 and the second housing 120 can be removably connected using a snap fastener. The liquid reservoir 200 and the flexible circuit board 300 are located in the first housing 110. The first housing 110 has an escape opening 110a, and at least a portion of the flexible circuit board 300 is located in the escape opening 110a. At least a portion of the second housing 120 is located in the escape opening 110a.

[0055] Configuring the housing 100 as a first housing 110 and a second housing 120 that can interlock facilitates assembly of the aerosol generating device. Providing a clearance opening 110a in the first housing 110 and positioning at least a portion of the flexible circuit board 300 within the clearance opening 110a allows the antenna 400 to be closer to the outer surface of the housing 100, thereby minimizing the impact of the housing 100 on the antenna 400's signal radiation and reception capabilities.

[0056] Exemplarily, both the first housing 110 and the second housing 120 may be non-metallic parts. Using non-metallic parts can further reduce the impact on the antenna 400 .

[0057] As an example, at least one side of the housing 100 located on the first sidewall 201 of the liquid reservoir 200 is non-metallic. This side of the housing 100 located on the first sidewall 201 of the liquid reservoir 200 faces the flexible printed circuit board 300, being relatively close and having the greatest impact on the antenna 400. Therefore, this portion is non-metallic. Other portions have less impact on the antenna 400, and some metal structures can be added as needed to meet specific design requirements.

[0058] Figure 6Schematic diagram of the decomposition structure of an aerosol generating device provided in an embodiment of the present application. Figure 6 As shown, the aerosol generating device further includes a display panel 500, which is located on a side of the liquid storage tank 200 away from the flexible circuit board 300. The display panel 500 is located between the liquid storage tank 200 and the first housing 110, which is a transparent structural member.

[0059] By arranging a display panel 500 and utilizing it to display information such as time, heating temperature, and the remaining amount of aerosol matrix in the liquid storage tank 200, the functionality of the aerosol generating device is further enhanced. Since the first housing 100 is a transparent structural member, it does not affect the display of the display panel 500. Arranging the display panel 500 on the side of the liquid storage tank 200 away from the flexible circuit board 300 places the display panel 500 at a greater distance from the flexible circuit board 300, thereby minimizing the mutual influence between the display panel 500 and the flexible circuit board 300. This improves the display quality of the display panel 500, the signal radiation capability of the antenna 400, and the signal reception capability of the antenna 400, thereby preventing interference with the signal of the antenna 400.

[0060] Figure 7 : is a schematic diagram of the internal structure of an aerosol generating device provided in an embodiment of the present application, Figure 7 At least the housing 100 is omitted. Figure 7 As shown, the aerosol generating device further includes a power supply assembly 610 and a printed circuit board 620. The power supply assembly 610 is located at the bottom of the liquid storage tank 200, and the printed circuit board 620 is located on a side of the power supply assembly 610 away from the liquid storage tank 200. The flexible circuit board 300 is connected to the printed circuit board 620.

[0061] The power supply component 610 is used to provide electrical energy for the operation of the aerosol generating device. Exemplarily, the power supply component 610 may include a battery.

[0062] The aerosol generating device further comprises a nozzle 630 , which is connected to the liquid storage tank 200 . The top of the liquid storage tank 200 is connected to the nozzle 630 , that is, the power supply assembly 610 and the nozzle 630 are located on opposite sides of the liquid storage tank 200 .

[0063] In this example, by arranging the power supply component 610 at the bottom of the liquid storage tank 200 and arranging the printed circuit board 620 on the side of the power supply component 610 away from the liquid storage tank 200, it is beneficial to increase the distance between the printed circuit board 620 and the flexible circuit board 300, thereby reducing the interference caused by the printed circuit board 620 to the antenna 400, which is beneficial to improving the signal radiation capability and signal receiving capability of the antenna 400, and further improving the communication quality.

[0064] Reference Figure 7 As shown, the flexible circuit board 300 includes a main body 310 and a connecting portion 320. The antenna 400 is located in the main body 310, which is located on a side of the power supply component 610 away from the printed circuit board 620. The connecting portion 320 connects the main body 310 and the printed circuit board 620.

[0065] The main body 310 provides a larger area for arranging the antenna 400 and the electronic device 311. The connecting portion 320 connects the main body 310 and the printed circuit board 620, which can make the antenna 400 farther away from the printed circuit board 620, which is beneficial to reduce the interference of the printed circuit board 620 on the antenna 400.

[0066] In some examples, the orthographic projection of the main body 310 on the outer surface of the liquid storage tank 200 may be located inside the outer surface of the liquid storage tank 200 , so as to provide better support for the main body 310 using the liquid storage tank 200 .

[0067] The above-described embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
