[0028] Embodiment 1

[0029] like Figure 1-Figure 4 As shown, the dustproof assembly for the electric hot air drying box proposed by the utility model includes a base 1, an air inlet pipe 2, a shell 3, an air outlet pipe 4, a collecting bucket 5, a rack 6, a rotating motor 7, a vertical threaded rod 8, a vertical threaded member 9, a gear 10, a rotating shaft 11, a vortex member 12, an impact member 13, a connecting rod 14, a torsion spring shell 15, a torsion spring 16, a transmission shaft 17, a filter screen 18, a clamping member 19, a bidirectional screw rod 20 and a clamping threaded member 21;

[0030] A shell 3 is provided on the top of the base 1; an air inlet pipe 2 is provided on the side of the shell 3; an air outlet pipe 4 is provided on the end of the shell 3 away from the air inlet pipe 2; a rotating motor 7 is provided on the top of the base 1; a rack 6 is provided on the base 1; a transmission structure for automatic dust removal is provided on the base 1; a clamping structure for clamping and fixing is provided on the base 1; a collecting bucket 5 is provided on the base 1;

[0031] The transmission structure includes a vertical threaded rod 8; the top output end of the rotating motor 7 is transmission-connected with the vertical threaded rod 8; a vertical threaded member 9 with a threaded connection is provided on the side of the vertical threaded member 8; a rotating shaft 11 with a rotation connection is provided on the side of the vertical threaded member 9; a gear 10 is provided on the side of the rotating shaft 11; the gear 10 is meshed and connected with the side of the rack 6; a plurality of groups of vortex members 12 are provided on the side of the rotating shaft 10; a connecting rod 14 is provided on the side of the vertical threaded member 9; a torsion spring housing 15 is provided on the end of the connecting rod 14 away from the vertical threaded member 9; a torsion spring 16 is provided inside the torsion spring housing 15; a transmission shaft 17 is provided on the end of the torsion spring 16 away from the torsion spring housing 15; a plurality of groups of impact members 13 are provided on the side of the transmission shaft 17; the side of the impact member 13 is in contact with the vortex member 12;

[0032] The clamping structure includes a clamping member 19 ; a clamping threaded member 21 is provided on the bottom of the clamping member 19 ; a bidirectional screw rod 20 is provided on the side surface of the bottom of the clamping threaded member 21 ; and the bidirectional screw rod 20 is rotatably connected to the bottom of the base 1 .

[0033] In this embodiment, the device can be used in combination with a drying box with weak dust removal ability, thereby avoiding the expensive cost of replacing the drying box as a whole and improving the air cleanliness inside the drying box. Compared with traditional devices, the device has the advantage of being easy to connect. At the same time, the device can effectively improve the long-term continuous use stability of the device through the automatic dust removal effect. When the device is in a working state, the combined structure of the shell 3 and the multiple groups of air inlet and outlet pipes can effectively improve the sealing of the device. At the same time, the pipeline structure reduces the difficulty of combining the device. The incoming air can be filtered through the filter screen 18. When in use, the rotating motor 7 drives the vertical threaded member 9 to reciprocate and rise and fall, so that the gear During the ginger process, the wheel 10 rotates due to the rack 6, and the rotating shaft 11 rotates the vortex 12 through the gear 10. At this time, an impact piece 13 is provided on the connecting rod 14 that follows the lifting and sliding. The impact piece 13 tilts and rotates under the drive of the vortex 12. At the same time, through the combination of the torsion spring 16 and the torsion spring housing 15, the impact piece 13 accumulates rotational elastic potential energy during rotation. When the vortex 12 rotates to a certain angle, the impact piece 13 suddenly separates from the vortex 12. At this time, the rotational elastic potential energy is released, thereby generating an impact on the filter 18. The vibration generated by the impact can shake the dust accumulated on the surface of the filter 18 into the inside of the collecting bucket 5, thereby solving the problem of reduced filtration efficiency of the filter 18.

[0036] The combination of the seal and the connecting joint can prevent leakage of the device when used in combination, and the structure of the rotating sleeve prevents the weight of the impact member 13 and the transmission shaft 17 from pressing on the torsion spring 16, thereby ensuring the stability of the torsion spring 16.
