Detailed Implementation

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings: Example 1:

[0028] like Figure 1 As shown, there is a seat ventilation pad with heating and cooling functions, including a seat cushion 1 and a backrest 2; the seat cushion 1 and the backrest 2 include an air outlet 4; the surface of the air outlet 4 is covered with a breathable material, specifically polyester, cotton-linen blend, Oxford cloth, knitted fabric, genuine leather, imitation leather, Nappa leather or aniline leather.

[0029] like Figures 2 to 5 As shown, air outlet section 4 has an air outlet track 41 distributed on it, and an air outlet ring hole 42 is provided at the turning point of the air outlet track 41; the air outlet track 41 includes an air inlet 411, which is located on the back side of the seat cushion 1 and the backrest 2.

[0030] A temperature control device 3 is provided on the back side of the seat cushion 1 or backrest 2. The temperature control device 3 includes a housing 31, a blower 33, and a semiconductor cooling chip 34. The blower 33 and the semiconductor cooling chip 34 are located in the inner cavity of the housing 31. The housing 31 has a first end face 311 and a second end face 312. The first end face 311 is connected to the air inlet 411 of the air outlet track 31. The second end face 412 is provided with an air outlet. The second end face 412 is away from the air outlet track 41 and is in contact with the air. The inner cavity of the housing 31 is connected to the inner and outer sides through the air outlet.

[0031] The blower 33 is located on the side near the air inlet 411 of the temperature control device 3, and the semiconductor cooling chip 34 is located on the side near the air outlet of the temperature control device 3.

[0032] Cooling effect: such as Figures 2 to 3As shown, natural wind is blown into the temperature control device 3 from the second end face 312, passes through the semiconductor cooling chip 34, cools the natural wind, and then reaches the blower fan 33; the blower fan 33 operates to bring the air into the air inlet 411 of the air outlet 4, the air seeps out through the air outlet track 41, and flows back in the air outlet ring hole 42 to complete the cooling. Example 2:

[0033] like Figures 3 to 5 As shown, the heating effect is as follows:

[0034] Heating wires 351 are distributed on the seat cushion 1 and backrest 2 of the seat ventilation cushion. Heating is achieved by direct heating through the heating wires 351. Natural air is blown from the second end face 312 into the temperature control device 3 through the semiconductor cooling chip 34 and then cooled before reaching the blower 33. When the blower 33 is running, the air enters the air inlet 411 of the air outlet 4. The air seeps out through the air outlet track 41 and flows back in the air outlet hole 42, thereby achieving temperature regulation. Example 3:

[0035] like Figure 3 , Figure 6 As shown, the heating effect is as follows:

[0036] A heater 352 is installed inside the outer casing 41. The heater 352 is located between the blower 43 and the thermoelectric cooler 44. The heater 452 is preferably the heating wire 451 in embodiment 2. When heating, the thermoelectric cooler 44 is turned off and the heater 452 is turned on. At this time, natural air is blown from the second end face 412 into the temperature control device 3, passes through the heater 452, and the natural air is heated before reaching the blower 43. The blower 43 operates and blows air into the air inlet 411 of the air outlet 4. The air seeps out through the air outlet track 41 and flows back in the air outlet ring hole 42 to complete the heating.
