The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example 1

As shown in fig. 1 and 2, the present embodiment provides a reciprocating mechanism for an electric brush, including a power source 1, a spur gear 2 and a converting mechanism, where the spur gear 2 is connected to the power source 1, the converting mechanism is configured to convert rotation of the power source 1 into reciprocating linear motion of a brush head 6 of the electric brush along an axis thereof, the converting mechanism includes a transmission member 3, a connection rod 4 and a guide sleeve 5, which are engaged with the spur gear 2, one end of the connection rod 4 is hinged to the transmission member 3, the other end of the connection rod 4 is fixedly connected to the guide sleeve 5, and the guide sleeve 5 is connected to the brush head 6 of the electric brush.

By arranging the reciprocating mechanism, the reciprocating mechanism is used for converting the rotation of the power source 3 into the reciprocating linear motion of the brush head part 6, so that the action of simulating the back-and-forth brushing of hands of people is realized, the people do not need to hold the brush to reciprocate back and forth during cleaning, the labor force of the people is reduced, and the cleaning efficiency is effectively improved; the utility model can provide higher frequency and faster linear speed in the using process, and solves the problems of insufficient cleaning of certain positions and low cleaning degree in the prior art.

As shown in fig. 2, the connecting rod 4 is connected to the guide sleeve 5 through the optical axis 7, the guide sleeve 5 is provided with a first mounting hole 8 and a second mounting hole 9 which are correspondingly arranged, the upper end of the connecting rod 4 is in interference fit with the first mounting hole 8, and the lower end of the connecting rod 4 is in clearance fit with the second mounting hole 9.

In addition, with reference to fig. 2, the outer circumferential surface of the guide sleeve 5 is provided with a caulking groove, a sealing ring 10 is installed in the caulking groove, and the reciprocating mechanism has a waterproof function by the sealing ring 10.
