[0002] People's living conditions are getting better and better, and people have higher and higher requirements for quality of life. When driving, in order to relieve waist fatigue, they usually lean on a back cushion. However, the cushion is relatively stuffy when used in summer, and the driver's back is prone to sweating, reducing the driver's comfort.

[0003] In the related art, a cushion with ventilation function usually fixes a fan in a supporting sponge, and the air outlet side of the fan is directly directed toward the back, resulting in uneven air outlet of the cushion, and the part of the human body directly blown by the fan is prone to cold. Utility Model Content

[0006] In a first aspect, the present application provides a ventilation mechanism, which adopts the following technical solution:

[0007] The ventilation mechanism includes a support plate and a plurality of centrifugal blowers, wherein the support plate is provided with a plurality of air outlet holes, a support tube is fixed on the back side of the support plate, the air outlet holes correspond one to one to the inner cavity of the support tube, the end of the support tube away from the air outlet holes is closed, a plurality of flow grooves are provided on the circumferential side wall of the support tube, and the flow grooves are arranged along the circumference of the support tube; the centrifugal blower is arranged on the support plate, and the blowing direction of the centrifugal blower is toward the side wall of the support tube.

[0008] 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 against the side wall of the support tube, so that the wind is blown out from the air outlet through the flow groove, and a number of 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 convenient for uniform heat dissipation, while preventing the back from being locally cold.

[0009] Optionally, the centrifugal blower is arranged at two ends of the back side of the support plate, and the blowing directions of the centrifugal blowers at two ends of the support plate are opposite to each other.

[0010] By adopting the above technical solution, the blowing directions of the centrifugal blowers are arranged opposite to 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.

[0011] Optionally, a through hole for air intake of a centrifugal blower is opened on the support plate, and the air inlet of the centrifugal blower faces the front side of the support plate.

[0012] By adopting the above technical solution, the air inlet side of the centrifugal blower faces the back, which is convenient for air intake and ensures the normal operation of the centrifugal blower.

[0013] Optionally, the support tube is provided with a wire threading opening for passing the wires of the centrifugal blower.

[0014] 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, makes it convenient to install the ventilation mechanism in the cushion, and is also convenient for storage and transportation.

[0015] Optionally, a heating wire is provided on the support plate.

[0016] 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.

[0017] Optionally, a vibration motor is provided on the support plate.

[0018] By adopting the above technical solution, the vibration motor vibrates to relax the back and waist muscles and achieve a massage effect.

[0019] 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.

[0020] By adopting the above technical solution and setting the support frame, after the support plate is installed in the cushion, the support frame provides support, thereby protecting the centrifugal blower and the support cylinder in the support frame, reducing the pressure on the centrifugal blower and the support cylinder, and preventing them from being crushed.

[0021] In a second aspect, the present application provides a cushion with a temperature regulating function, which adopts the following technical solution:

[0022] A cushion with temperature regulating function comprises an outer cover, a supporting sponge layer and the above-mentioned ventilation mechanism, wherein the supporting sponge layer is provided with a housing cavity for accommodating the ventilation mechanism, the front side of the supporting sponge layer is provided with a connecting hole facing the air outlet, and the outer cover covers the outside of the supporting sponge layer.

[0023] By adopting the above technical solution, the support tube flows the wind 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.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The wind is blown out from several air outlets through the flow slots. Several support tubes protrude from the back of the support plate. The support tubes have a diversion effect, so that the wind is evenly dispersed on the support plate, making the air outlet uniform and facilitating uniform heat dissipation on the back;

[0026] 2. The centrifugal blowers are set in opposite directions to each other, which increases the blowing effect and improves the heat dissipation effect;

[0027] 3. The wire threading port makes it easy to organize the wires, install the ventilation mechanism in the cushion, and also facilitate the storage and transportation of the ventilation mechanism. BRIEF DESCRIPTION OF THE DRAWINGS
