[0022] The utility model is described in detail below in conjunction with the accompanying drawings. The embodiments of the utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the utility model, and cannot be interpreted as limiting the utility model. The directional terms such as left, middle, right, top, and bottom in the embodiments of the utility model are only relative concepts or are based on the normal use state of the product, and should not be considered as restrictive.

[0023] A wind supply plate, such as Figure 3 , Figure 4 and Figure 5 As shown, it includes a plate body 23, and the plate body 23 is preferably made of plastic material, which has strong plasticity and low cost. A baffle 21 is integrally connected around the plate body 23. In other embodiments, the plate body 23 and the baffle 21 can be bonded or clamped. The baffle 21 and the plate body 23 form a trough body with an opening upward. A support platform 22 is distributed on the bottom surface of the trough body. The side of the support platform 22 is provided with a guide surface for guiding the wind to the opening direction of the trough body. The support platform 22 can be a frustum structure. The side of the frustum structure is a plane or an arc surface and forms a guide surface. The guide surface is inclined upward and is used to change the wind direction. The frustum structure can be a circular cone or a prism cone; in other embodiments, the support platform 22 can also be a hemispherical structure (not shown), and the spherical surface of the hemispherical structure is the guide surface, so that the airflow in the trough body flows upward along the spherical surface;

[0024] The fan 24 is distributed in the tank body, and the fan 24 is fixedly connected to the tank body. The fan 24 is provided with a first air outlet 241 and a second air outlet 242. The bottom surface of the fan 24 is close to or in contact with the top surface of the plate body 23. The first air outlet 241 faces the support platform 22, and the second air outlet 242 faces the opening direction of the tank body. There is an inlet and an outlet in the first air outlet 241 and the second air outlet 242, that is, when the first air outlet 241 is an outlet, the second air outlet 242 is an inlet. vent; when the second air vent 242 is the air outlet, the first air vent 241 is the air inlet; the top surface of the fan 24 and the top surface of the support platform 22 are both flush with the top surface of the baffle 21, or are both lower than the top surface of the baffle 21, so as to facilitate the assembly of the air supply plate in the seat cushion; when the top surface of the fan 24 and the top surface of the support platform 22 are both lower than the top surface of the baffle 21, the top surface of the fan 24 and the top surface of the support platform 22 are preferably flush, so that in some applications, it is convenient to provide users with a smoother support effect.

[0025] When working, the fan 24 sucks in the air above the trough body and blows the air into the trough body. After the air in the trough body flows, it flows along the guide surface to the outside of the trough body, so that the air in the trough body can quickly exchange with the air above it; since there are no leakage points on the bottom surface and side walls of the trough body, the air entering the trough body can only be discharged from its notch. Therefore, compared with the technical solution in the prior art that the air supply plate is provided with ventilation holes, the plate body 23 and the baffle 22 in the utility model form a trough body with only an upper opening, so that the wind in the trough body can only be discharged from its notch, and then when the fan 24 is in low energy consumption or a small number of fans 24 are used, the inside and outside of the trough body can also have a better air exchange effect.

[0026] Combination Figure 2 and Figure 3 As shown, the trough body is an elongated structure, and the fans 24 are all located on one side of the trough body or on two opposite sides of the trough body; three fans 24 are used in this embodiment, and the three fans 24 are respectively located in the middle and both ends of the elongated structure. The second air outlet 242 of the fan 24 located in the middle of the elongated structure can be an air outlet, and the first air outlet 241 of other fans is an air outlet, which can meet the needs of some users for differentiated air supply in the middle of the seat cushion; in addition, in other embodiments, when two fans 24 are used, the two fans 24 can be respectively located at both ends of the elongated structure.

[0027] Combination Figure 6 As shown, in other embodiments, the tank body can also be a disc-shaped structure, the fans 24 are evenly distributed along the baffle 22 and close to the baffle 22, and the first air outlet 241 is preferably oriented toward the center of the tank body to allow the seat cushion to dissipate heat more evenly.

[0028] An active ventilated seat cushion provided with an air supply plate, such as Figure 1 , Figure 2 and Figure 5 As shown, it includes a ventilated pad 3 and the above-mentioned air supply plate 2, the ventilated pad 3 and the air supply plate 2 are stacked up and down, the ventilated pad 3 covers the notch of the slot body, and the side of the notch is located at the edge of the bottom surface of the ventilated pad 3. In order to facilitate the ventilated pad 3 and the air supply plate 2 to be restricted together, the two can be directly fixedly connected, or the ventilated pad 3 and the air supply plate 2 can be sleeved in the cover 1, and the top surface 11 of the cover 1 is a breathable material; the top surface 11 of the cover 1 is a ventilated cloth or a ventilated woven pad or a plastic material with through holes or a rubber material with through holes, and the ventilated cloth is preferably a 3D mesh cloth; the ventilated woven pad can be a stone woven pad, a bamboo woven pad, etc.; the bottom surface of the cover 1 is a material with poor ventilation effect, such as leather, canvas, and polyester; to prevent the cover 1 from sliding on the bench seat, rubber anti-slip convex points or convex strips are distributed on the bottom surface outside the cover 1. To improve comfort, the ventilation pad 3 is an air fiber pad, a cotton pad, a mesh rubber pad or a straw pad, and the thickness is greater than 1 cm. The structure of the air fiber pad is as follows: Figure 7As shown, after the ventilated pad 3 is placed on the support platform 22 , the user sits on the ventilated pad 3 , and due to the isolation effect of the ventilated pad 3 , the user cannot feel the protrusion of the support platform 22 .

[0029] When in use, the square-shaped active ventilation cushion can be used on a stool or a seat, while the disc-shaped active ventilation cushion can be placed on the ground and used for leisure and entertainment; in addition, a small number of fans are used in the utility model to achieve active ventilation and heat dissipation of the active ventilation cushion. When the active ventilation cushion uses fewer fans, a battery pack can be used to power these fans to adapt to places without power supply conditions.
