[0024] Please see Figures 1 to 7 This utility model provides a technical solution:

[0025] An office chair with a ventilation and heat dissipation structure includes a seat 4, armrests 2 symmetrically fixed to the outer side of the seat 4, a backrest 1 fixedly fixed to one side of the seat 4, ventilation holes 3 equidistantly provided inside the backrest 1 and the seat 4, ventilation seats 5 fixedly fixed to one side of the backrest 1 and the seat 4, a fan 6 installed inside the ventilation seat 5, a fixed frame 8 fixedly fixed to one side of the ventilation seat 5, a sliding seat 11 slidably connected inside the fixed frame 8, a first spring 14 equidistantly provided between the sliding seat 11 and the fixed frame 8, a locking block 12 fixedly fixedly connected to one side of the sliding seat 11, a dust filter 7 slidably connected inside the ventilation seat 5, and a connecting plate 10 fixedly connected to one side of the dust filter 7. The interior of the 0 is provided with equally spaced slots 21 for use with the locking block 12; when air cooling is required, the fan 6 is turned on, and the dust filter 7 can filter the air. The fan 6 can blow the filtered air into the heat dissipation channel inside the backrest 1 and seat 4, and blow it out through the ventilation holes 3 on the outside of the backrest 1 and seat 4, thereby cooling the user's back and buttocks and drying the user's sweat, enhancing the comfort during use. The first spring 14 can drive the sliding seat 11 to move and reset, and the sliding seat 11 drives the locking block 12 to move into the slot 21, thereby locking the position of the connecting plate 10 and facilitating the installation and fixation of the dust filter 7.

[0026] Furthermore, the fixed frame 8 is symmetrically fixedly connected with a limiting slide bar 15, and the sliding seat 11 is slidably connected to the limiting slide bar 15. The limiting slide bar 15 can limit the movement of the sliding seat 11 and prevent the sliding seat 11 from deviating when moving.

[0027] Furthermore, the fixed frame 8 is equidistantly connected with connecting rods 16, and one end of the connecting rod 16 is fixedly connected with a push rod 18. The sliding seat 11 is provided with an inclined groove 19 that cooperates with the push rod 18. The connecting rod 16 drives the push rod 18 to move, so that it cooperates with the inclined groove 19, thereby squeezing and driving the sliding seat 11 to move during the movement of the push rod 18.

[0028] Furthermore, a push plate 13 is fixedly connected to the end of the connecting rod 16 away from the push rod 18. A second spring 17 is sleeved on the outside of the connecting rod 16 and on one side of the push plate 13. The push plate 13 drives the connecting rod 16 to move, and the second spring 17 drives the push plate 13 to move and reset.

[0029] Furthermore, a connecting block 9 is fixedly connected to the side of the connecting plate 10 away from the dust filter 7, which facilitates the pulling of the connecting plate 10.

[0030] Furthermore, anti-slip textures 20 are symmetrically fixed to the outer side of the connecting block 9. The anti-slip textures 20 can increase the friction and make it easier to pull the connecting block 9.

[0031] Working principle:

[0032] When cooling is required during use, the fan 6 is activated. The dust filter 7 filters the air, which is then blown into the cooling channels inside the backrest 1 and seat 4 by the fan 6 and out through the ventilation holes 3 on the outside of the backrest 1 and seat 4. This cools the user's back and buttocks, dries sweat, and enhances comfort. To disassemble, clean, or replace the dust filter 7, push the push plate 13, compressing the second spring 17. The push plate 13, through the connecting rod 16, moves the push rod 18, engaging with the inclined groove 19. As the push rod 18 moves, it presses and moves the sliding seat 11, causing the sliding seat 11 to move the locking block 12 away from the locking groove 21. This allows the connecting block 9 to be pulled, removing the dust filter 7 for easy disassembly, cleaning, or replacement. The operation is convenient.
