[0009] By adopting the above technical solution, when in use, the ventilation mechanism is installed in the cushion, the front of the support plate faces the back, and the centrifugal blower blows directly at the side wall of the support tube, so that the wind is blown out from the air outlet through the circulation groove. Several support tubes protrude from the back side of the support plate. The support tubes have a diversion effect, so that the wind is evenly dispersed on the support plate, the air outlet is uniform, and the back is facilitated to dissipate heat evenly, while preventing the back from getting locally cold.

[0010] Optionally, the centrifugal blower is arranged at both ends of the back side of the support plate, and the blowing directions of the centrifugal blowers at both ends of the support plate are opposite to each other.

[0011] By adopting the above technical solution, the blowing directions of the centrifugal blowers are arranged to face each other, thereby increasing the blowing effect. The opposite blowing makes it easier for the wind to be blown out from the air outlet, thereby achieving a good heat dissipation effect.

[0012] Optionally, the support plate is provided with an air intake for a centrifugal blower, and the air intake of the centrifugal blower faces the front of the support plate.

[0015] By adopting the above technical solution, multiple centrifugal blowers are provided, which makes the wires more messy. The wire threading port makes it easy to organize the wires, improves the overall correlation between the wires and the support plate, facilitates the installation of the ventilation mechanism in the cushion, and is also convenient for storage and transportation.

[0016] Optionally, a heating wire is provided on the support plate.

[0017] By adopting the above technical solution and arranging the electric heating wire, the cushion can be heated for convenient use. In winter, the heated cushion improves the user's comfort.

[0018] Optionally, a vibration motor is provided on the support plate.

[0019] By adopting the above technical solution, the vibration motor vibrates to relax the back and waist muscles and achieve a massage effect.

[0020] Optionally, a support frame is fixed to the circumferential edge of the back side of the support plate, and a plurality of centrifugal blowers and a plurality of support cylinders are located in the support frame.

[0021] By adopting the above technical solution and setting up the support frame, after the support plate is installed in the cushion, the support frame provides support, thereby protecting the centrifugal blower and support cylinder in the support frame, reducing the pressure on the centrifugal blower and support cylinder, and preventing them from being crushed.

[0022] In a second aspect, the present application provides a cushion with a temperature regulating function, which adopts the following technical solution:

[0023] A cushion with a temperature regulating function comprises an outer cover, a supporting sponge layer and the ventilation mechanism according to any one of claims 1 to 7, wherein a housing cavity for accommodating the ventilation mechanism is provided in the supporting sponge layer, a connecting hole facing an air outlet is provided on the front side of the supporting sponge layer, and the outer cover covers the outside of the supporting sponge layer.

[0024] By adopting the above technical solution, the support tube flows the air blown by the centrifugal blower and blows it out through the circulation slot and the air outlet, so that the air outlet of the cushion is uniform and the comfort of use is improved.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The wind is blown out from several air outlets through the circulation slots. Several support tubes protrude from the back of the support plate. The support tubes have a diversion effect, which makes the wind evenly dispersed on the support plate, making the air uniform and facilitating uniform heat dissipation on the back;

[0035] 1 , the support plate 1 is provided with a plurality of air outlet holes 11, each having an inner diameter of 1-2 cm, and arranged in a matrix on the support plate 1. The side of the support plate 1 facing the back is the front side, and the side of the support plate 1 away from the back is the back side.

[0036] Referring to Figures 1 and 2 , a support tube 3 is fixed to the back side of the support plate 1. Each air outlet 11 corresponds to the inner cavity of a support tube 3, and the end of the support tube 3 away from the air outlet 11 is closed. Several flow slots 31 are defined along the circumferential sidewall of the support tube 3. The flow slots 31 are evenly spaced along the circumference of the support tube 3. In this embodiment, four flow slots 31 are defined on the sidewall of the support tube 3.

[0037] Referring to Figures 1 and 2, centrifugal blower 2 is bolted to support plate 1, with the blower 2 directed toward the sidewall of support tube 3.

[0038] 1 , a wire threading opening 32 is provided on the side wall of the support tube 3 for the wires of the centrifugal blower 2 to pass through. In the embodiment, the wire threading opening 32 is a flow groove 31 . The wires of the centrifugal blower 2 are limited on the support tube 3 through the wire threading opening 32 so that the wires are neatly stored.

[0039] 2 , a heating wire groove is provided on the front of the support plate 1. The heating wire groove is arranged in a winding manner on the front of the support plate 1. A heating wire 4 is fixed in the heating wire groove.

[0040] 1 , a mounting groove for a vibration motor 5 is provided on the back of the support plate 1 , in which a vibration motor 5 is fixed. Two vibration motors 5 are fixed, and the two vibration motors 5 are located at both ends of the back of the support plate 1 in the horizontal direction.

[0041] Referring to Figure 1 , a support frame 13 is fixed to the circumferential edge of the back side of the support plate 1. Several centrifugal blowers 2 and several support cylinders 3 are located within the support frame 13. The support frame 13 is used to support the support plate 1, making the back side of the support plate 1 less likely to be squeezed, thereby protecting the centrifugal blowers 2 and support cylinders 3.
