[0037] An embodiment of the present application provides a motherboard assembly 100, which is applied to electronic equipment, such as Figure 1 and Figure 2 As shown, the mainboard assembly 100 includes a mainboard 10, a bracket 20 and a light-transmitting member 30. The mainboard 10 is a printed mainboard on which various electronic components for realizing the functions of the electronic device are installed. The electronic components include a controller and at least one light source 11. The controller is used to control the electronic device to perform corresponding functions.

[0038] In some embodiments, the controller can be a general-purpose processor, a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), a single-chip microcomputer, an ARM (Acorn RISC Machine) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of these components.

[0039] The bracket 20 is assembled on the mainboard 10. Specifically, the bracket 20 can be assembled on the mainboard 10 by screws, buckles, riveting, etc. The bracket 20 is provided with at least one light guide channel 21, and the light source 11 is arranged in the light guide channel 21, so that the light beam emitted by the light source 11 can propagate along the guide channel.

[0040] The light-transmitting member 30 is assembled on the bracket 20. The light-transmitting member 30 includes a light-transmitting area 31. The light-transmitting area 31 is exposed to the housing of the electronic device. The light-transmitting area 31 may include multiple light-transmitting areas. The multiple light-transmitting areas 31 can display different contents when combined with each other, so that the user can know the current working state of the electronic device or the current remaining power of the electronic device by observing the light-transmitting area 31. The light-guiding channel 21 is connected to the light-transmitting area 31, so that the light-guiding channel 21 can guide the light emitted by the light source 11 to the light-transmitting area 31, and the light-transmitting area 31 can generate light under the illumination of the light source 11.

[0041] Thus, through the mainboard assembly 100 in this embodiment, since the light source 11 is directly set on the mainboard 10 in the mainboard assembly 100, the mainboard 10 can directly provide power to the light source 11, and there is no need for a separate circuit board to provide power to the light source 11. Therefore, compared with using a separate display screen module, the manufacturing cost of the electronic device can be reduced.

[0042] In some embodiments, Figure 2 As shown, the main board 10 includes a plurality of light sources 11 , and the bracket 20 is provided with a plurality of light guide channels 21 , each of which is provided with a light source 11 to avoid cross-lighting between the light sources 11 , thereby affecting the display effect of the light-transmitting area 31 .

[0043] In some embodiments, Figure 2 As shown, the light-transmitting member 30 is a thin film, so that the light-transmitting member 30 can be directly attached to the bracket 20 by adhesive, which is convenient for assembly. Further, in order to facilitate the positioning of the installation position of the film 30, a positioning hole 32 is provided on the film 30, and a positioning portion 22 is provided on the bracket 20, so that during the installation of the film 30, the positioning portion 22 is aligned with the positioning hole 32, so that the positioning portion extends into the positioning hole 32, thereby realizing the installation and positioning of the film 30.

[0044] In some embodiments, Figure 1 and Figure 2 As shown, a key switch 12 is provided on the main board 10, and the key switch 12 is electrically connected to the controller. A key pressed by a user may be provided on the electronic device. When the key is pressed, the key touches the key switch 12, so that the key switch 12 generates an electrical signal, and the electrical signal is then sent to the controller. The controller can control the start-up of the electronic device according to the electrical signal.

[0045] To facilitate key triggering of the key switch 12 , the bracket 20 is provided with a first through hole 23 connected to the key switch 12 . That is, the key switch 12 is exposed through the first through hole 23 , so that the key passes through the first through hole 23 to trigger the key switch 12 .

[0046] Further in some embodiments, Figure 1 and Figure 2As shown, the bracket 20 is also provided with two second through holes 24, and the two second through holes 24 are distributed on both sides of the first through hole 23. The second through holes 24 contain an elastic member 241, and the elastic member 241 is used to support the key that triggers the key switch 12. Therefore, when the key is pressed by the user, the key triggers the key switch 12, and the key squeezes the elastic member 241 so that the elastic member 241 produces elastic deformation. When the user releases the pressing force on the key, the elastic member 241 can reset the key under the action of the elastic restoring force. The elastic member 241 can be any one of a spring, silicone, rubber, a spring, etc.

[0047] Specifically, Figure 2 As shown, one end of the elastic member 241 is fixed on the main board 10 , and the other end protrudes out of the second through hole 24 , so that the elastic member 241 can stably and effectively generate elastic deformation.

[0048] In some embodiments, Figure 1 and Figure 2 As shown, a plurality of chips 13 are disposed on the mainboard 10 , and the plurality of chips 13 are disposed around the bracket 20 , so that the bracket 20 can be easily installed.

[0049] Furthermore, in some embodiments, the light source 11 is mounted on the mainboard 10 by means of a surface mount technology (SMT), and there is no need to manually electrically connect the light source 11 and the mainboard 10, thereby further saving the manufacturing cost of the electronic device.

[0050] like Figure 3 As shown, an embodiment of the present application also provides an aerosol generating device 200, the aerosol generating device 100 includes a battery cell 210, a mainboard assembly 100 and a heating element 220, the mainboard assembly 100 is provided with a controller of the aerosol generating device 100, the battery cell 210 and the heating element 220 are respectively electrically connected to the controller, so that the controller can control the battery cell 210 to provide electric energy to the heating element 220. A longitudinally extending chamber 230 is also provided in the aerosol generating device 200, the chamber 230 is used to accommodate a solid aerosol generating matrix 300 (such as a cigarette) used in conjunction with the aerosol generating device 200, and the heating element 220 is attached to the outer wall of the chamber 230, so that the aerosol generating matrix 300 in the chamber 230 can be heated, and part of the active material filled in the aerosol generating matrix 300 can generate aerosol by volatilization under heat. The battery cell 210 serves as the power supply of the aerosol generating device 200, and it can be a rechargeable battery cell or a non-rechargeable battery cell.

[0051] The aerosol generating device 200 also includes an airflow channel 240, which connects the external air and the chamber 230. When the user uses the aerosol generating matrix 300 to inhale, the external cold air can enter the chamber 230 through the airflow channel 240, and then enter the aerosol generating matrix 300 and carry the aerosol in the aerosol generating matrix 300 to escape for the user to inhale.

[0052] The aerosol generating substrate 300 preferably adopts a tobacco-containing material that releases volatile compounds from the product when heated; or it can also be a non-tobacco material that can be heated and suitable for electric heating and smoking. The aerosol generating substrate 300 preferably adopts a solid substrate, which can include one or more of powder, particles, fragments, strips or sheets of one or more of herb leaves, tobacco leaves, homogenized tobacco, and expanded tobacco; or the solid substrate can contain additional tobacco or non-tobacco volatile flavor compounds to be released when the substrate is heated.

[0053] The heating element 220 can be any one of a mesh resistance heating wire wrapped on the outer wall of the chamber 230 , an infrared electric heating coating coated on the outer wall of the chamber 230 , or a thick film heating element printed on the outer wall of the chamber 230 .

[0054] In some embodiments, Figure 4 As shown, the aerosol generating device 200a may also be used to heat a liquid aerosol generating substrate to generate an aerosol.

[0055] Specifically, the aerosol generating device 200a includes a shell 210a, which is provided with an air inlet 211a for external air to enter the aerosol generating device 200a, and an air outlet 212a for the user to inhale the aerosol. A liquid storage chamber 220a is provided in the shell 210a, and the liquid storage chamber 220a is used to store liquid aerosol generating matrix. An air guide tube 260a extends longitudinally in the liquid storage chamber 220a, and one end of the air guide tube 260a is connected to the air outlet 212a. In order to seal the liquid storage chamber 220a, a sealing member 230a is also provided in the shell 210a, and the sealing member 230a is interference fit with the inner wall of the shell 210a to seal the liquid storage chamber 220a.

[0056] The air guide tube 260a is provided with a liquid guiding element 240a and a heating element 250a combined with the liquid guiding element 240a. The liquid guiding element 240a partially extends into the liquid storage chamber 220a. The liquid guiding element 240a is made of a hygroscopic material, such as non-woven fabric, cotton fiber, glass fiber or porous material. The heating element 250a can be combined with the liquid guiding element 240a by printing, deposition, sintering or physical assembly, or wound on the liquid guiding element 240a, so that the liquid matrix in the liquid storage chamber 220a can be absorbed by the liquid guiding element 240a. The liquid guiding element 240a further transfers the liquid matrix to the heating element 250a through the tiny gaps or microporous structures inside it. The heating element 250a heats the liquid matrix to atomize it to generate an aerosol, and releases the aerosol in the air guide tube 260a. The seal 230a is provided with an air vent 231a, which is connected to the air duct 260a. When the user inhales at the air outlet 212a, external air enters the aerosol generating device 200a through the air inlet 211a, then flows into the air vent 231aa through the internal air flow channel, and enters the air duct 260a through the air vent 231a, and finally carries the aerosol in the air duct 260a to the air vent 231a for the user to inhale.

[0057] The aerosol generating device 200a also includes the mainboard assembly 100, the battery cell 270a and the airflow sensor 280a in the above embodiment. The mainboard assembly 100 is provided with a controller of the aerosol generating device 200a. The battery cell 270a, the heating element 250a and the airflow sensor 280a are electrically connected to the controller respectively. When the user inhales at the air outlet 212a, the external air enters the aerosol generating device 200a from the air inlet 211a, and then the airflow sensor 280a senses the inhaled airflow and generates a sensing signal, which is further sent to the controller, and the controller controls the battery cell 270a to provide electrical energy to the heating element 250a.

[0058] like Figure 2 As shown, the mainboard assembly 100 includes a first light-transmitting area R1 and a second light-transmitting area R2, each of which is composed of a plurality of adjacent light-transmitting regions 31, the first light-transmitting area R1 is used to display the remaining liquid volume of the liquid storage chamber 220a, and the second light-transmitting area R2 is used to display the remaining power of the battery cell 270a. For example, when the remaining liquid volume of the liquid storage chamber 220a is large, all the light-transmitting regions 31 in the first light-transmitting area R1 generate light, and when the remaining liquid volume of the liquid storage chamber 220a is small, only one light-transmitting region 31 in the first light-transmitting area R1 generates light.

[0059] Similarly, when the remaining power of the battery cell 270a is high, all light-transmitting regions 31 in the first light-transmitting region R2 generate light, and when the remaining power of the battery cell 270a is low, only one light-transmitting region 31 in the first light-transmitting region R1 generates light.
