There is a cross bar 32, which is arranged perpendicularly to the piston rod 31. One end of the cross bar 32 away from the piston rod 31 is connected to the end of the drying box 10. By setting the dust box 20, dust and impurities can be effectively collected and blocked, and dust and impurities are prevented from entering the interior of the drying box 10, thereby ensuring the cleanliness and drying effect of the interior of the dryer. The combined use of the filter box 21 and the filter net 23 can more effectively filter impurities and dust in the air, further improving the cleanliness and drying effect of the drying process. The setting of the blower 12 and the electric heating network 13 can quickly blow hot air into the interior of the drying box 10, thereby improving the drying efficiency. At the same time, the design of the air inlet pipe 14 being connected to the interior of the dust box 20 allows the hot air to be more evenly distributed to every corner, further improving the drying efficiency.

Since the hot air can be emitted more directly from the air outlets 11, the drying can be faster.

[0032] Specifically, the cross section of the filter box 21 is T-shaped, and the filter box 21 is plugged into and fits with the dustproof box 20, which increases the stability of the filter box 21 and also ensures its sealing during use.

[0033] It is worth noting that the dustproof mesh plate 22 is provided with a plurality of air inlet holes arranged evenly and equidistantly, so that air can enter the dustproof box 20 more evenly, thereby improving the drying efficiency.

[0034] Among them, the cross-section of the filter 23 is U-shaped, the top of the filter 23 is connected to the dustproof mesh plate 22, and a secondary filter 24 is also installed in the dustproof box 20. The secondary filter 24 is arranged at the bottom of the filter 23, which further enhances the filtering effect in the dustproof box 20, thereby improving the cleanliness and drying effect of the drying process.

[0035] In addition, a fixed top seat 33 is installed on the top of the lifting cylinder 30. The top edge of the fixed top seat 33 is provided with a number of evenly equidistant through holes arranged in a ring shape, which is convenient for installation or disassembly, increases the stability of the lifting cylinder 30, and also ensures its sealing during use.

[0036] The working principle of the dustproof mechanism of the hot air dryer of the utility model is as follows: when in use, the operator turns on the dryer, and the blower 12 draws external air into the dustproof box 20 through the air inlet pipe 14. The air passes through the filter box 21 on the top of the dustproof box 20, and the filter screen 23 therein blocks and collects dust and impurities, and the clean air continues to enter the drying box 10. When the drying is completed, the dryer is turned off and the whole process ends.
