[0019] The following is combined with Figure 1 - Figure 5 This application is described in further detail.

[0020] Example:

[0021] An office chair with ventilation function, referring to Figure 1 - Figure 5 , including a seat surface 2, a seat back 6 is hinged on one side of the seat surface 2, and a ventilation hole 1 is opened on both the seat surface 2 and the seat back 6. A concave groove 10 is opened on the side of the bottom of the seat back 6 away from the seat surface 2, and a concave block 11 is slidably installed in the concave groove 10. A dust box 8 is provided on one side of the concave block 11. A plurality of through holes 2 15 are opened on the side of the dust box 8 close to the seat back 6. The plurality of through holes 2 15 are coaxially arranged with the ventilation holes on the seat back 6. A plurality of fans 9 are fixedly installed on one side of the dust box 8. A filter is provided on the side of the dust box 8 close to the fan 9. A locking mechanism is provided between the block 11 and the dust box 8; by providing the dust box 8 and the fan 9, the dust in the multiple ventilation holes on the chair back 6 can be cleaned, thereby improving the cleanliness of the chair ventilation holes, avoiding dust accumulation affecting air circulation, and improving the comfort of use. The cleanliness of the chair ventilation holes is improved, avoiding dust accumulation affecting air circulation, and improving the comfort of use. The ventilation plate 5 can be easily disassembled through the limit block 17 and the limit groove 16, thereby thoroughly cleaning the dust and dirt between the ventilation plate 5 and the support plate 4, and keeping the office chair clean and hygienic.

[0022] Reference Figure 1 、 Figure 2 and Figure 5 Lifting columns 3 are fixedly installed on both sides of the seat surface 2, and supporting plates 4 are fixedly installed on the tops of the two lifting columns 3. Ventilation plates 5 are provided on the tops of the two supporting plates 4. Multiple ventilation holes are opened on the two ventilation plates 5, and the height of the supporting plates 4 can be adjusted.

[0023] Reference Figure 5, both sides of the top of the two supporting plates 4 are provided with limiting grooves 16, and both sides of the bottom of the two ventilation plates 5 are fixedly installed with limiting blocks 17. The limiting blocks 17 slide with the limiting grooves 16. Magnetic materials are used on the limiting grooves 16 and the limiting blocks 17. The limiting grooves 16 and the limiting blocks 17 attract each other. The magnetic force can be used to increase the attraction of the contact surface to limit the sliding of the limiting blocks 17.

[0024] Reference Figure 3 - Figure 4 The locking mechanism includes a rotating rod 12, a limiting plate 13 and a through hole 14. A rotating rod 12 is provided on one side of the concave groove 10. One end of the rotating rod 12 is threadedly connected to the concave groove, and the other end of the rotating rod 12 is fixedly installed with a limiting plate 13. A through hole 14 is provided at the bottom of the dust box 8. The limiting plate 13 is coaxially arranged with the through hole 14. The limiting plate 13 is fitted with one side of the dust box 8, and the limiting plate 13 can be rotated so that the rotating rod 12 drives the limiting plate 13 to rotate, forming a cross shape with the through hole 14, thereby locking the dust box 8.

[0025] Reference Figure 1 - Figure 2 A lifting base 1 is fixedly installed at the bottom of the seat surface 2, protective plates 7 are set on both sides of the seat surface 2, and the material wrapped on the top of the seat surface 2 is set as a sponge pad, which can drive the seat surface 2 to rise and fall to adapt to different heights.

[0026] Working principle: when in use, you can start the fan 9, and then manually slide the dust box 8 so that the dust box 8 moves close to one side of the chair back 6, and the dust in the ventilation hole 1 of the chair back 6 is sucked into the dust box 8 through the through hole 2 15. After sucking, you can rotate the limit plate 13, and the limit plate 13 drives the rotating rod 12 to rotate. After the rotating rod 12 is loosened, the limit plate 13 is coaxial with the through hole 14, and then take out the dust box 8 to process the dust inside. After the processing is completed, align the through hole 14 with the limit plate 13 and pass it through, and then rotate the limit plate 13 so that the limit plate 13 and the through hole 1 14 are cross-intersected, thereby locking the dust box 8. When it is necessary to process the dust in the ventilation hole 2 on the supporting plate 4, you can manually slide the ventilation plate 5 so that the limit block 17 disengages the limit groove 16, and then clean the ventilation plate 5 and the inside of the supporting plate 4.

[0027] The above describes an exemplary implementation of an office chair with ventilation function provided by the present disclosure with reference to a preferred embodiment. However, it will be understood by those skilled in the art that, without departing from the concept of the present disclosure, various variations and modifications may be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure may be combined in various ways without exceeding the scope of protection of the present disclosure, which is determined by the appended claims.
