[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Referring to Figures 1-7 , a seat cushion with a heat dissipation function includes a housing 1. An installation frame 2 is fixedly arranged inside the housing 1. A honeycomb board 3 is fixedly arranged inside the installation frame 2. A heat conduction sheet 11 is fixedly arranged on the front side of the honeycomb board 3. A refrigeration sheet 12 is fixedly arranged on the top of the heat conduction sheet 11. A heat sink 9 is fixedly arranged on the top of the refrigeration sheet 12. The number of heat sinks 9 is multiple, and the multiple heat sinks 9 are linearly distributed. Through the heat sink 9, the temperature of the high-temperature side of the refrigeration sheet 12 can be dissipated. A protection board 10 is fixedly arranged on the front side of the refrigeration sheet 12. A heat dissipation component is arranged inside the installation frame 2. A connecting plate 16 is fixedly arranged inside the installation frame 2. A connecting component is arranged inside the connecting plate 16. A contact pad 14 is arranged on the connecting plate 16 through the connecting component. A skirt 15 is fixedly arranged on the surface of the contact pad 14. The housing 1 is made of reticulated sponge. The heat conduction sheet 11 is made of thermal grease. The housing 1 made of reticulated sponge can allow gas to enter the surface of the installation frame 2. The heat conduction sheet 11 made of thermal grease has good heat conduction performance, which can quickly transfer the temperature on the surface of the contact pad 14 to the heat conduction sheet 11, and the temperature is reduced by the refrigeration sheet 12. For this seat cushion with a heat dissipation function, when the refrigeration sheet 12 is started, the temperature of the heat conduction sheet 11 drops. The temperature of the contact pad 14 in contact with the heat conduction sheet 11 is reduced through the heat conduction sheet 11, and an air flow is generated by the heat dissipation component to blow on the surface of the heat sink 9 to dissipate the heat of the high-temperature side of the refrigeration sheet 12, so that the temperature of the side of the refrigeration sheet 12 in contact with the heat conduction sheet 11 is always kept low, thereby keeping the temperature of the contact pad 14 always low. This seat cushion can prevent the user's buttocks from accumulating temperature, thus avoiding the user's buttocks from getting hot and humid, and improving the comfort of using the seat cushion.

[0024] Specifically, the heat dissipation component includes a support frame 4 fixedly arranged inside the installation frame 2. A bracket 6 is fixedly arranged inside the support frame 4. A rotary motor 7 is fixedly arranged inside the bracket 6. A blade 8 is fixedly arranged at the output end of the rotary motor 7. The number of blades 8 is two, and the two blades 8 are symmetrically distributed. First through holes 5 are opened on the left and right sides of the installation frame 2. A second through hole 13 is opened on the top of the installation frame 2. When the rotary motor 7 is started to drive the blade 8 to rotate, the temperature on the surface of the heat sink 9 can be dissipated, and the heat dissipation speed of the high-temperature side of the refrigeration sheet 12 can be accelerated. The first through holes 5 and the second through hole 13 can allow gas to enter the inside of the installation frame 2 and flow inside the installation frame 2.

[0025] Specifically, the connecting component includes a hook surface 17 fixedly arranged inside the connecting plate 16. A loop surface 18 is arranged on the front side of the hook surface 17. The loop surface 18 is fixedly connected to the contact pad 14. The contact pad 14 and the heat conducting sheet 11 are in contact through the mutual contact of the loop surface 18 and the hook surface 17. Different contact pads 14 and skirt edges 15 can be replaced by removing the hook surface 17 and the loop surface 18.

[0026] All the electrical components appearing in this text are electrically connected to an external main controller and 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0027] During use: The high temperature on the surface of the contact pad 14 causes the temperature of the heat conducting sheet 11 to rise. The Peltier cooler 12 and the rotary motor 7 are started. Starting the Peltier cooler 12 causes the temperature of the heat conducting sheet 11 to drop, and then the temperature of the contact pad 14 in contact with the heat conducting sheet 11 is reduced through the heat conducting sheet 11. Starting the rotary motor 7 can drive the blades 8 to rotate, generating an air flow to blow on the surface of the heat sink 9 to dissipate heat from the relatively high-temperature side of the Peltier cooler 12. At the same time, the honeycomb plate 3 can enhance the overall supporting effect of the seat cushion, preventing the user from deforming and denting the heat conducting sheet 11 and the contact pad 14. The skirt edge 15 can prevent dust from adhering to the sides of the contact pad 14 and the housing 1.

[0028] In summary, for the seat cushion with a heat dissipation function, starting the Peltier cooler 12 causes the temperature of the heat conducting sheet 11 to drop, reduces the temperature of the contact pad 14 in contact with the heat conducting sheet 11 through the heat conducting sheet 11, and generates an air flow through the heat dissipation component to blow on the surface of the heat sink 9 to dissipate heat from the relatively high-temperature side of the Peltier cooler 12, keeping the temperature of the side of the Peltier cooler 12 in contact with the heat conducting sheet 11 at a low temperature all the time, so that the temperature of the contact pad 14 is kept low all the time. This seat cushion can prevent the user's buttocks from accumulating heat, thus avoiding the user's buttocks from getting hot and humid, and improving the comfort of using the seat cushion.
