1. The novel toothbrush comprises an air inlet pipe, 2 parts of a support plate, 3 parts of a reciprocating screw rod, 4 parts of a cross bar, 5 parts of a sliding block, 6 parts of an arc-shaped plate, 7 parts of bristles, 8 parts of a driven gear, 9 parts of a negative pressure fan, 10 parts of a connecting rod, 11 parts of a gear ring, 12 parts of a sleeve, 13 parts of a spring, 14 parts of a fine adjustment rod and 15 parts of a rotating shaft.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings 1 to 6.
During the working process of the dust collector, a large amount of dust can be deposited in the air inlet pipe 1 of the dust collector, the dust deposition increases the running resistance of the dust collector, the dust collecting pressure difference is increased, and the dust collecting effect is reduced. In order to avoid the phenomenon, the novel dust collector is arranged to regularly clean the accumulated dust in the air inlet pipe 1, and the dust collecting effect of the dust collector is ensured. When dust in the air inlet pipe 1 needs to be cleaned, a negative pressure fan 9 in the driving device is started, a rotating shaft 15 of the negative pressure fan 9 drives a gear ring 11 to rotate through a connecting rod 10, the gear ring 11 drives a reciprocating lead screw 3 to rotate around a supporting plate 2 through a driven gear 8, the reciprocating lead screw 3 drives a sliding block 5 to transversely reciprocate along a transverse shaft along with the rotation of the reciprocating lead screw 3, an arc-shaped plate 6 also reciprocates simultaneously along with the reciprocating movement of the sliding block 5, bristles 7 on the arc-shaped plate 6 clean the dust on the inner wall of the air inlet pipe 1, and the negative pressure fan 9 in the driving device also attracts the cleaned dust to be discharged through an outlet of the air inlet pipe 1.
When the accumulated dust in the air inlet pipe 1 is cleaned, the accumulated dust is difficult to avoid to form an irregular accumulation phenomenon on the inner wall of the air inlet pipe 1 to become a dust accumulation block, sometimes the action of a cleaning device is possibly influenced by the overlarge dust accumulation block, or excessive wear to the brush staples 7, and a fine adjustment device is arranged for reducing the influence of the phenomenon, when the brush hairs 7 encounter the dust accumulation block with larger volume in the working process of the cleaning device, and when the brush hairs 7 brush the dust accumulation block, the dust accumulation block can act with the arc-shaped plate 6 through the brush hairs 7 to enable the arc-shaped plate 6 to be stressed, so that the arc-shaped plate 6 moves close to the axis of the air inlet pipe 1, and as the arc-shaped plate 6 moves close to the axis of the air inlet pipe 1, the fine adjustment rod 14 slides along the sleeve 12 into the sleeve 12 and compresses the spring 13, after the brush passes through the dust accumulation block, the spring 13 will extend itself and bring the arc-shaped plate 6 towards the initial state by means of the fine adjustment lever 14. The brush can reduce the volume of the dust accumulation block gradually by repeatedly passing through the dust accumulation block, and finally the dust accumulation block is also cleaned. The central angle corresponding to the arc-shaped plate 6 is one hundred and fifteen degrees. Can be convenient for maintain arc-shaped plate 6, brush hair 7, guarantee three cleaning device of group simultaneously and can furthest carry out comprehensive clearance to the laying dust.
