Turntable transmission structure of electric mop

Abstract

The invention discloses a turntable transmission structure of an electric mop, which comprises a lower shell and a cover plate which are fixedly connected, and turntables arranged at the lower part of the lower shell, wherein driving gears are arranged between the lower shell and the cover plate, and the upper end and the lower end of each driving gear are rotationally connected with the cover plate and the lower shell through bearings respectively; a spline is arranged in the middle of the lower end of the driving gear, a limiting column protruding upwards is arranged in the middle of the turntable, a spline hole matched with the spline is formed in the limiting column, the spline comprises at least two key position parts which are evenly distributed, and the driving gear is inserted into the spline hole of the turntable through the spline and fixedly connected with the turntable. The turntable is connected with the driving gear through a spline, and the upper end and the lower end of the driving gear are rotationally connected through bearings, so that the driving gear rotates stably and drives the turntable stably, stable rotation of the turntable is guaranteed, abrasion of the joint of the driving gear and the turntable is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a rotating disk transmission structure of an electric mop. Background technique [0002] As an electric cleaning device, the electric mop uses it to clean the ground more labor-saving than the traditional mop, and it is more convenient to clean the mop. With the continuous improvement of people's living standards, more and more people start to use electric mops to replace traditional manual mops. When the electric mop is used, the mop will rub against the ground to clean the ground. Therefore, the electric mop generally uses a worm gear transmission mechanism, which can have a high torque and can effectively drive the mop to move. In the structure of the electric mop, the gear and the turntable are connected by transmission, so that the turntable rotates to drive the mop to rotate. The gears and turntables currently on the market are generally connected by a square...

AI Technical Summary

Problems solved by technology

The gears and turntables currently on the market are generally connected by a square shaft and a shaft hole or a hexagonal shaft and a shaft hole. After a period of use, the edges of the square shaft or hexagonal shaft will inevitably wear and tear. In severe cases, the transmission structure formed by the shaft and the hole will fail, so that the turntable cannot be driven to rotate, thereby reducing the service life of the mop
