[0035] Please refer to Figure 1 and Figure 2 , the aerosol generating device 100 of the embodiment of the present application includes a housing 10, a display screen 20 and a touch panel 30. The display screen 20 is disposed on the housing 10, and the display screen 20 is used to display information of the aerosol generating device 100. The touch panel 30 is disposed on the housing 10 and is electrically connected to the display screen 20. The touch panel 30 and the display screen 20 are of a split structure, and the touch panel 30 is used for a user to touch to change the display information of the display screen 20.

[0036] Among them, the housing 10 is a structure in the aerosol generating device 100 that can accommodate and protect devices such as the display screen 20 and the touchpad 30. The material of the housing 10 includes but is not limited to plastics, aluminum alloys, copper, iron, steel, and carbon fiber composite materials, etc. Exemplarily, the material of the housing 10 is plastic, so that the housing 10 can be made lighter, which is beneficial to the lightweight of the aerosol generating device 100.

[0037] The display screen 20 is a structure in the aerosol generating device 100 for displaying information of the aerosol generating device 100. The display screen 20 includes but is not limited to cathode ray tube displays, liquid crystal displays, LED displays, and OLED displays, etc. In some embodiments of the present application, the information of the aerosol generating device 100 includes but is not limited to heating mode, battery level, number of puffs, and time and date, etc. In some embodiments, the display screen 20 is disposed inside the housing 10, and the display surface of the display screen 20 is blocked by the housing 10. Thus, the housing 10 can protect the display screen 20 and reduce the possibility of damage to the display screen 20. It can be understood that the area of the housing 10 opposite to the display screen 20 has a good light transmission effect. In other embodiments, the display screen 20 is disposed on the housing 10, and the display surface of the display screen 20 is exposed to the outside.

[0038] The touchpad 30 is a structure in the aerosol generating device 100 for the user to touch to change the display information of the display screen 20. The touchpad 30 includes but is not limited to capacitive touchpads and resistive touchpads, etc. In some embodiments of the present application, the touchpad 30 can utilize the principle of capacitance induction to achieve its function. Exemplarily, when the user's finger approaches or touches the touchpad 30, the capacitance value will change accordingly. The touchpad 30 can output an operation signal representing the user's touch action after detecting the change in the capacitance value, and the display screen 20 can respond to the operation signal to change the display information. For example, the display screen 20 can respond to the operation signal to change from a page displaying the heating mode to a page displaying the battery level.

[0039] In some embodiments, the display screen 20 is electrically connected to the touchpad 30 through an electrical connector. Thus, signals can be transmitted between the display screen 20 and the touchpad 30 by using the electrical connector, thereby ensuring the normal operation of the touchpad 30 and the display screen 20. It should be noted that in some embodiments, the electrical connector includes but is not limited to quick-disconnect connectors such as terminal connectors and socket connectors, etc.

[0040] In some other embodiments, the aerosol generating device 100 further includes a circuit board 40 disposed within the housing 10, and the display screen 20 and the touchpad 30 are both disposed on the circuit board 40. Thus, the signal transmission between the display screen 20 and the touchpad 30 can be achieved by using the circuit board 40, thereby improving the stability of signal transmission and ensuring the timeliness of the response of the display screen 20 to the operation signal of the touchpad 30. In addition, since the display screen 20 and the touchpad 30 are both disposed on the circuit board 40, the display screen 20, the touchpad 30 and the circuit board 40 can form an integral structure, thereby reducing the space size occupied by the display screen 20 and the touchpad 30, which is conducive to the miniaturization of the aerosol generating device 100.

[0041] In some embodiments, the display screen 20 and the touchpad 30 are disposed on the same side of the housing 10. Thus, compared with the case where the display screen 20 and the touchpad 30 are disposed on different sides of the housing 10, on the one hand, the space size occupied by the display screen 20 and the touchpad 30 can be reduced, which is conducive to the miniaturization of the aerosol generating device 100; on the other hand, it is convenient for the user to operate, and the user can view the change of the display content while touching, preventing the user from constantly switching between the display screen 20 and the touchpad 30 during the use of the aerosol generating device 100.

[0042] Further, the display screen 20 and the touchpad 30 can be simultaneously disposed on the side where the front surface of the housing 10 is located. For example, if the housing 10 is in the shape of a cuboid as a whole, the front surface is the largest surface of the housing 10, so as to increase the space available for arranging the display screen 20 and the touchpad 30 and improve the display and touch areas. Of course, the display screen 20 and the touchpad 30 can also be simultaneously disposed on the side where the side surface of the housing 10 is located. For example, they are disposed on the side surface adjacent to the front surface, which is not limited herein.

[0043] In the aerosol generating device 100 according to the embodiment of the present application, the touchpad 30 is disposed on the housing 10 and is electrically connected to the display screen 20, and the touchpad 30 and the display screen 20 are of a split structure, that is, the touchpad 30 and the display screen 20 are two independent structural members, and the touchpad 30 is responsible for sensing touch operations, and the display screen 20 is responsible for information display. Thus, the user can change the display information of the display screen 20 without touching the display screen 20, thereby reducing the possibility of scratches or damage to the display screen 20 caused by touching and ensuring the display effect of the display screen 20. And, compared with the case where the display screen 20 is a touch display screen 20, the size, shape and position design of the touchpad 30 can be adaptively adjusted according to requirements, improving the user experience.

[0044] In addition, if the display screen 20 is a touch display screen, the display screen 20 needs to integrate the display panel and the touch sensing layer. At this time, due to factors such as manufacturing processes, material selection, and assembly, the production cost of the display screen 20 is relatively high. In some embodiments of the present application, the touchpad 30 and the display screen 20 are of a split structure. In this way, the touchpad 30 and the display screen 20 do not need to be integrated together, thereby simplifying the manufacturing process and reducing the production cost of the aerosol generating device 100.

[0045] The aerosol generating device 100 will be further explained below with reference to the accompanying drawings.

[0046] Please refer to Figure 1 and Figure 2 , if the display screen 20 is a touch display screen, considering the size and production cost of the aerosol generating device 100, the size design of the display screen 20 cannot be too large. However, a smaller size is not conducive to the user's touch operation on the display screen 20, which will affect the normal use of the aerosol generating device 100. In some embodiments of the present application, the cross-section of the touchpad 30 is larger than the cross-section of the display screen 20. As can be seen from the above, the touchpad 30 and the display screen 20 are separately arranged. Thus, the user's touch area is increased, which facilitates the user's operation and ensures the normal use of the aerosol generating device 100. In addition, compared with increasing the size of the touch display screen, increasing the cross-section of the touchpad 30 so that the cross-section size of the touchpad 30 is larger than the cross-section size of the display screen 20 can reduce the production cost of the aerosol generating device 100.

[0047] Please refer to Figure 2 and Figure 3 , in some embodiments, the touchpad 30 includes a substrate 31 and a touch slider 33. The substrate 31 is disposed on the housing 10 and is electrically connected to the display screen 20. The touch slider 33 is disposed on the substrate 31, and the touch slider 33 is used for the user to touch to change the display information of the display screen 20.

[0048] Specifically, in some embodiments, when the user touches the touch slider 33, the capacitance value will change accordingly. The touchpad 30 can output an operation signal representing the user's touch action after detecting the change in the capacitance value. Exemplarily, the touchpad 30 can output an operation signal representing the user's touch direction after detecting the change in the capacitance value, and the display screen 20 can respond to the operation signal to realize the change of the display information.

[0049] Further, in some embodiments, the touch slider 33 includes a plurality of conductive members 331. A part of the plurality of conductive members 331 is arranged at intervals along the first direction X and together forms a first touch area 301. Another part of the plurality of conductive members 331 is arranged at intervals along the second direction Y and together forms a second touch area 303. The first direction X and the second direction Y intersect. In some embodiments, the material of the conductive member 331 includes at least one of copper, aluminum, silver, and gold. It can be understood that in addition to the above materials, the conductive member 331 can also be other conductive materials, which will not be exemplified one by one here.

[0050] It should be noted that in some embodiments, the first direction X and the second direction Y intersect. In one example, the first direction X and the second direction Y are perpendicular. For example, the first direction X is the length direction of the aerosol generating device 100, and the second direction Y is the height direction of the aerosol generating device 100. In another example, as long as the first direction X and the second direction Y intersect, the included angle between the two can be any angle between (0° and 180°), for example, the included angle between the two can be 15°, 30°, 45°, 60°, 75°, 100°, 115°, 120°, or 135°, etc. In the embodiments of the present application, only the example where the first direction X and the second direction Y are perpendicular is used for illustration.

[0051] Specifically, in some embodiments, two adjacent conductive members 331 can form a capacitor. When the user does not touch the conductive member 331, the capacitance value remains constant; when the user touches the conductive member 331, the capacitance value will change. In this way, the touch panel 30 can output an operation signal according to the change of the capacitance value. Among them, when the first direction X is the length direction of the aerosol generating device 100 and the second direction Y is the height direction of the aerosol generating device 100, the user can realize the up and down (i.e., the first direction X) page turning of the display screen 20 through the touch operation in the first touch area 301, and realize the left and right (i.e., the second direction Y) page turning of the display screen 20 through the touch operation in the second touch area 303. It can be understood that in some embodiments, the user's touch can be a click touch or a swipe touch, etc.

[0052] In some embodiments, the centers of the first touch area 301 and the second touch area 303 coincide. And as can be seen from the above, the first direction X and the second direction Y intersect. Therefore, the first touch area 301 and the second touch area 303 can be arranged in a "cross" shape, which can reduce the space size occupied by the first touch area 301 and the second touch area 303 while facilitating user operation.

[0053] Please continue to refer to Figure 2 and Figure 3, in some embodiments, the number of conductive members 331 in the first touch region 301 includes at least three, and the number of conductive members 331 in the second touch region 303 includes at least three. Specifically, in some embodiments, the number of conductive members 331 in the first touch region 301 may include any value greater than 3, such as 3, 4, 5, 6, 7, 8, 9, and 10; correspondingly, the number of conductive members 331 in the second touch region 303 may include any value greater than 3, such as 3, 4, 5, 6, 7, 8, 9, and 10.

[0054] If the number of conductive members 331 in the first touch region 301 is less than three, the number of positions on the touchpad 30 that can detect touch operations will decrease, resulting in a reduction in the accuracy of software algorithm recognition, and a decrease in the sensitivity and accuracy of the touchpad 30 in responding to touch operations; correspondingly, if the number of conductive members 331 in the second touch region 303 is less than three, the number of positions on the touchpad 30 that can detect touch operations will decrease, resulting in a reduction in the accuracy of software algorithm recognition, and a decrease in the sensitivity and accuracy of the touchpad 30 in responding to touch operations. In the embodiments of the present application, the number of conductive members 331 in the first touch region 301 includes at least three, and the number of conductive members 331 in the second touch region 303 includes at least three. Thus, the number of positions on the touchpad 30 that can detect touch operations can be increased, thereby improving the accuracy of software algorithm recognition, and further improving the sensitivity and accuracy of the touchpad 30 in responding to touch operations.

[0055] Please refer to Figure 3 , and in combination with Figures 4 to 6 , in some embodiments, the length L1 of the first touch region 301 is greater than or equal to 10 mm, and the length L2 of the second touch region 303 is greater than or equal to 10 mm. Specifically, in some embodiments, the length L1 of the first touch region 301 may be any value greater than 10 mm, such as 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm; correspondingly, the length L2 of the second touch region 303 may be any value greater than 10 mm, such as 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, 16 mm, 17 mm, 18 mm, 19 mm, and 20 mm.

[0056] If the length L1 of the first touch area 301 is less than 10 mm, the touch area on the touchpad 30 is small, which will affect user operation on the one hand; on the other hand, it will lead to a decrease in the recognition accuracy of the software algorithm, and the sensitivity and accuracy of the touchpad 30 in responding to touch operations will decline; correspondingly, if the length L2 of the second touch area 303 is less than 10 mm, the touch area on the touchpad 30 is small, which will affect user operation on the one hand; on the other hand, it will lead to a decrease in the recognition accuracy of the software algorithm, and the sensitivity and accuracy of the touchpad 30 in responding to touch operations will decline. In some embodiments of the present application, the length L1 of the first touch area 301 is greater than or equal to 10 mm, and the length L2 of the second touch area 303 is greater than or equal to 10 mm, thereby increasing the touch area on the touchpad, which can facilitate user operation on the one hand; on the other hand, it can improve the recognition accuracy of the software algorithm and the sensitivity and accuracy of the touchpad 30 in responding to touch operations.

[0057] Please continue to refer to Figure 3 , and in combination with Figures 4 to 6 , in some embodiments, the size W1 of the conductive member 331 in the first direction X is greater than or equal to 2 mm; and / or, the size W2 of the conductive member 331 in the second direction Y is greater than or equal to 2 mm. Specifically, in some embodiments, the size W1 of the conductive member 331 in the first direction X can be any value greater than 2 mm such as 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, and 12 mm; correspondingly, the size W2 of the conductive member 331 in the second direction Y can be any value greater than 10 mm such as 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, and 12 mm.

[0058] If the size W1 of the conductive member 331 in the first direction X is less than 2 mm, the sensing area of the conductive member 331 is small, which will affect user operation on the one hand; on the other hand, it will lead to a decrease in the recognition accuracy of the software algorithm, and the sensitivity and accuracy of the touchpad 30 in responding to touch operations will decline; correspondingly, if the size W2 of the conductive member 331 in the second direction Y is less than 2 mm, the sensing area of the conductive member 331 is small, which will affect user operation on the one hand; on the other hand, it will lead to a decrease in the recognition accuracy of the software algorithm, and the sensitivity and accuracy of the touchpad 30 in responding to touch operations will decline. In some embodiments of the present application, the size W1 of the conductive member 331 in the first direction X is greater than 2 mm; and / or, the size W2 of the conductive member 331 in the second direction Y is greater than 2 mm, thereby increasing the sensing area of the conductive member 331, which can facilitate user operation on the one hand; on the other hand, it can improve the recognition accuracy of the software algorithm and the sensitivity and accuracy of the touchpad 30 in responding to touch operations.

[0059] In some embodiments, in the first direction X, the spacing distance P1 between two adjacent conductive members 331 is (0, 2 mm]; in the second direction Y, the spacing distance P2 between two adjacent conductive members 331 is (0, 2 mm]. Specifically, in some embodiments, in the first direction X, the spacing distance P1 between two adjacent conductive members 331 can be any value among 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, and 2.0 mm or any numerical value between any two of these values. In the second direction Y, the spacing distance P2 between two adjacent conductive members 331 can be any value among 0.2 mm, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm, 1.4 mm, 1.6 mm, 1.8 mm, and 2.0 mm or any numerical value between any two of these values.

[0060] If the spacing distance between two adjacent conductive members 331 is 0, that is, the two conductive members 331 together form a large conductive member (hereinafter referred to as the combined conductive member), then when the user touches the combined conductive member, it is difficult for the touchpad 30 to determine the exact touch position, which will affect the software recognition accuracy; if the spacing distance between two adjacent conductive members 331 is greater than 2 mm, the distance between two adjacent conductive members 331 is relatively large, which will affect the convenience of user operation. In some embodiments of the present application, in the first direction X, the spacing distance P1 between two adjacent conductive members 331 is (0, 2 mm]; in the second direction Y, the spacing distance P2 between two adjacent conductive members 331 is (0, 2 mm]. Thus, on the one hand, it is convenient for the touchpad 30 to determine the exact touch position and improve the software recognition accuracy; on the other hand, it can prevent the distance between two adjacent conductive members 331 from being too large, which is convenient for user operation.

[0061] In some embodiments, the cross-sectional shape of the conductive member 331 includes a square ( Figure 4 as shown), a circle ( Figure 5 as shown), and a W shape ( Figure 6 as shown), at least one of which. It can be understood that in other embodiments, the cross-sectional shape of the conductive member 331 further includes, but is not limited to, a triangle, an ellipse, a rhombus, etc.

[0062] Specifically, in some embodiments, the cross-sectional shapes of the plurality of conductive members 331 are all the same. For example, the cross-sectional shapes of the plurality of conductive members 331 are all square; for another example, the cross-sectional shapes of the plurality of conductive members 331 are all circular; for yet another example, the cross-sectional shapes of the plurality of conductive members 331 are all W-shaped. In other embodiments, the cross-sectional shapes of the plurality of conductive members 331 are different. For example, the cross-sectional shapes of some of the plurality of conductive members 331 are square, and the cross-sectional shapes of another part of the plurality of conductive members 331 are circular.

[0063] If the display screen 20 and the touchpad 30 are arranged on different sides of the housing 10, for example, the display screen 20 and the touchpad 30 are respectively arranged on opposite sides of the housing 10, then when the user needs to change the display information of the display screen 20, the user needs to perform blind operation on the touchpad 30; or, the user needs to flip the housing 10 to switch from the side where the display screen 20 is located to the side where the touchpad 30 is located, and then perform a touch operation on the touchpad 30, and the operation accuracy is relatively low, which is not convenient for the user to use. Please refer to Figure 1 and Figure 2 , in some embodiments of the present application, the display screen 20 and the touchpad 30 are arranged on the same side of the housing 10. In this way, the operation accuracy can be improved, which is convenient for the user to use.

[0064] In some embodiments, the housing 10 includes a first side, a second side, a third side, and a fourth side that are connected in sequence. The first side of the housing 10 and the third side of the housing 10 are opposite and have equal areas; the second side of the housing 10 and the fourth side of the housing 10 are opposite and have equal areas. The area of the first side of the housing 10 is larger than the area of the second side of the housing 10. Among them, the display screen 20 and the touchpad 30 can both be arranged on the first side of the housing 10; or, both are arranged on the third side of the housing 10.

[0065] Please refer to Figure 1 and Figure 2 , in some embodiments, the housing 10 includes a housing body 11 and a cover body 13. The housing body 11 is provided with an opening 111, and the opening 111 is used for a part of the display screen 20 to extend out of the housing body 11, and for a part of the touchpad 30 to extend out of the housing body 11. The cover body 13 is connected to the housing body 11, and the cover body 13 is used to cover the opening 111, the display screen 20, and the touchpad 30. Among them, the setting of the cover body 13 can, on the one hand, protect the display screen 20, the touchpad 30, and the internal structure of the housing body 11, thereby ensuring the normal operation of the aerosol generating device 100 and extending the service life of the aerosol generating device 100; on the other hand, it can prevent the user from directly seeing the internal structure of the housing body 11 through the opening 111, thereby ensuring the appearance effect of the aerosol generating device 100.

[0066] In some embodiments of the present application, the touchpad 30 abuts against the inner wall of the cover 13. Specifically, the touchpad 30 abutting against the inner wall of the cover 13 may be that the touch slider 33 closely adheres to the inner wall of the cover 13 and there is no gap between the touch slider 33 and the inner wall of the cover 13. In this way, the sensitivity of the touchpad 30 to touch operations can be improved. It should be noted that, in some embodiments, the cover 13 may be made of at least one of materials such as plastic, plastic, and glass.

[0067] In some embodiments, the connection between the housing body 11 and the cover 13 can be a detachable connection or a non-detachable connection. The detachable connection includes but is not limited to screw connection, snap connection, or a combined connection of screw connection and snap connection. The non-detachable connection includes but is not limited to glue connection, welding, or a combined connection of glue connection and welding.

[0068] In some embodiments, the cover 13 includes a first sub-part and a second sub-part that are joined. The first sub-part faces the display screen 20, and the second sub-part faces the touchpad 30. The light transmittance of the first sub-part is greater than that of the second sub-part. Thus, on the one hand, the light of the display screen 20 can pass through the first sub-part more to be observed by the user, thereby improving the display effect of the display screen 20; on the other hand, it is difficult for the user to see the internal structure of the touchpad 30 and the housing body 11 through the second sub-part, thereby improving the appearance effect of the aerosol generating device 100.

[0069] Further, in some embodiments, the second sub-part is light-impermeable. In this way, it can further prevent the user from seeing the internal structure of the touchpad 30 and the housing body 11 through the second sub-part, improving the appearance effect of the aerosol generating device 100.

[0070] It should be noted that, in some embodiments, when the cover 13 is made of plastic, the first sub-part can be made of light-transmitting plastics such as PMMA (acrylic), PC (polycarbonate), PP (polypropylene), PET (polyethylene terephthalate), and PS (polystyrene); the second sub-part can be made of light-impermeable plastics such as ABS plastic and PE (polyethylene).

[0071] Please refer to Figure 1 and Figure 2 , in some embodiments, the housing 10 is provided with an insertion hole 15 for the aerosol generating substrate 200 to extend into the housing 10. The display screen 20 is closer to the insertion hole 15 than the touchpad 30. Among them, the aerosol generating substrate 200 is an element that can generate aerosol. Specifically, the aerosol generating substrate 200 can be made into fine particles by heating or ultrasonic oscillation and mixed with air to form aerosol. The form of the aerosol generating substrate 200 can be solid or liquid. Among them, the aerosol generating substrate 200 can be sheet-shaped or column-shaped, etc.

[0072] Generally, when the user holds the aerosol generating device 100 for suction, the user's holding area (the area where the human hand contacts the housing 10) will be away from the aerosol generating substrate 200, that is, the user's holding area will be away from the insertion hole 15. Therefore, if the display screen 20 is farther from the insertion hole 15 than the touchpad 30, the human hand will block the display of the display screen 20, affecting the display effect of the display screen 20. Thus, in some embodiments of the present application, the display screen 20 is closer to the insertion hole 15 than the touchpad 30, so as to prevent the human hand from blocking the display screen 20, and thus the display effect of the display screen 20 can be ensured.
