[0029] Specifically, such as Figure 1-3 As shown, the first ventilation mechanism includes a first fan position 202 integrally formed in the middle of the seat cushion bottom plate 2 and recessed downward, a first silent fan 8 installed on the inner side of the first fan position 202, a first battery position 203 opened at the upper end of the seat cushion bottom plate 2 and located at the front end of the first fan position 202, a first battery 9 installed on the inner side of the first battery position 203, and a first button switch 10 installed on the front side of the upper end of the seat cushion bottom plate 2 and with the button part penetrating downward through the seat cushion bottom plate 2. When the first button switch 10 is turned on, an airflow from bottom to top can be generated between the seat cushion bottom plate 2 and the hard seat cushion 3.

[0030] Among them, the lower end of the seat cushion bottom plate 2 is located below the first fan position 202 and is provided with a plurality of first ventilation holes 201, which facilitates the outside air to pass through the bottom of the seat cushion bottom plate 2 and enter between the seat cushion bottom plate 2 and the hard seat cushion 3. The upper end of the hard seat cushion 3 is provided with a plurality of first uniform air holes 301, which facilitates the air between the seat cushion bottom plate 2 and the hard seat cushion 3 to be blown to the top of the hard seat cushion 3 in multiple directions.

[0031] Specifically, such as Figure 1-3As shown, the second ventilation mechanism includes a second fan position 602 integrally formed at the top front end of the cushion base plate 6, a second silent fan 11 installed inside the second fan position 602, a second battery position 603 opened at the bottom front end of the cushion base plate 6, a second battery 12 installed inside the second battery position 603, and a second button switch 13 installed in the middle of the front end of the cushion base plate 6 and with the button part extending backward through the cushion base plate 6. When the second button switch 13 is turned on, an airflow from front to back can be generated between the cushion base plate 6 and the hard cushion 7.

[0032] Among them, the rear end of the cushion base plate 6 is located behind the second fan position 602 and the second battery position 603, and a second ventilation hole 601 is provided to facilitate the outside air to enter between the cushion base plate 6 and the hard cushion 7 through the back of the cushion base plate 6.

[0036] Working principle: During use, when the user needs to perform active ventilation of the seat cushion part or the backrest part according to the actual use situation, he can press the first button switch 10 on the seat cushion bottom plate 2 or the second button switch 13 on the hard cushion 7 respectively. After the first button switch 10 is pressed, the first battery 9 can power the first silent fan 8, and the first silent fan 8 will continue to rotate. At this time, an airflow from bottom to top can be generated between the seat cushion bottom plate 2 and the hard seat cushion 3, and the outside air can enter the cavity between the seat cushion bottom plate 2 and the hard seat cushion 3 through the first ventilation hole 201 in advance, so as to perform the first step of flow heat dissipation treatment on the hard seat cushion 3 to avoid the problem of continuous heat storage in the hard seat cushion 3. The air after use can continue to move upward through multiple first uniform air holes 301 to between the user's limbs and the hard seat cushion 3, which is beneficial to the user. The second step of multi-directional air supply treatment is performed on the thighs and buttocks of the user to prevent sweat from continuing to adhere to the hard seat cushion 3 and the user's limbs; after the second button switch 13 is pressed, the second battery 12 can power the second silent fan 11, and the second silent fan 11 will continue to rotate. At this time, an airflow from back to front can be generated between the cushion base plate 6 and the hard cushion 7, and the outside air can enter the cavity between the cushion base plate 6 and the hard cushion 7 through the second ventilation hole 601 in advance, and the hard cushion 7 can be subjected to the first step of flow heat dissipation treatment to avoid the occurrence of the problem of continuous heat storage in part of the hard cushion 7. After use, the air can continue to move forward through multiple second uniform air holes 701 to between the user's limbs and the hard cushion 7, and the user's waist can be subjected to the second step of multi-directional air supply treatment to prevent sweat from continuing to adhere to the hard cushion 7 and the user's limbs.
