[0023] Application description: In the process of learning, a study chair is needed. The seat cushion 3 provided by the utility model is specially used for the study chair. In the process of using the study chair, the seat cushion 3 needs to be placed on the study chair first to ensure that the study chair is in a ventilated state when in use.

[0024] like Figure 1 - Figure 6 As shown, the utility model provides a technical solution: a universal seat cushion for a learning chair, comprising a chassis 2, a fixing plate 1 is arranged at the bottom of the chassis 2, a cavity 18 is arranged inside the fixing plate 1, a fan 16 is fixedly installed on the inner wall of the cavity 18, a seat cushion 3 is fixedly installed on the upper end surface of the chassis 2, a plurality of air holes are opened on the upper end surface of the chassis 2, a connecting component is arranged at the bottom of the chassis 2, and a limiting component is also fixedly installed at the bottom of the chassis 2.

[0025] The utility model is provided with a fixing plate 1, a cavity 18, a fan 16, a cushion 3 and ventilation holes. During use, the fan 16 can cool down the user's buttocks, keep the buttocks dry, thereby preventing sweat stains and increasing the user's comfort.

[0026] like Figure 2 As shown, the connecting assembly includes two rectangular blocks 9, a fixing belt 10 is fixedly installed on the outer wall of the rectangular block 9, a buckle 19 is fixedly installed on the bottom of the chassis 2 at a position corresponding to the rectangular block 9, the end of the fixing belt 10 passes through the buckle 19, a second round hair piece 14 is fixedly installed on the outer wall of the fixing belt 10, and a second bristle piece 15 is fixedly installed on the end of the fixing belt 10.

[0027] By setting the rectangular block 9, the fixing belt 10, the notch buckle 19, the second round hair piece 14, and the second hair piece 15, during the use of this design, the staff can fix the fixing plate 1 and the chassis 2, and can use the fan 16 according to the needs of the user. When the fan 16 is damaged, it is also convenient for the staff to replace the fan 16.

[0028] like Figure 2 As shown, the limiting assembly includes two fixed blocks 5, and elastic bands 6 are fixedly installed at the bottom of the two fixed blocks 5. A first round hair piece 7 is fixedly installed on the outer wall of the elastic band 6 on one side, and a first bristle piece 11 is fixedly installed on the inner wall of the elastic band 6 on the other side.

[0029] By providing the fixing block 5, the elastic band 6, the first round hair piece 7 and the first bristle piece 11, the staff can fix the seat cushion 3 on the study chair through the elastic band 6 during use, which is convenient for the staff to install and disassemble it and is more convenient to use.

[0030] like Figure 4As shown, an airbag 17 is arranged inside the seat cushion 3, and an air inlet hole is opened on the airbag 17. The air inlet hole of the airbag 17 penetrates the outer wall of the seat cushion 3, and the inner wall of the air inlet hole is slidably connected with an airbag plug 8.

[0031] By providing the airbag 17 and the airbag plug 8, the design staff can inflate or deflate the airbag 17 according to the needs of the user during use, making the use more comfortable.
