Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 4, the embodiment of the present application provides a brush head for a lithium battery multifunctional brush, which includes a protective cover 4 and a rolling brush 1 rotatably connected in the protective cover 4. The shaft axis department of 1 one end of round brush is provided with the step hole, the downthehole pressure of step is equipped with axle sleeve 2, can dismantle through detachable connector and be connected between axle sleeve 2 and the protection casing 4. And a clamping groove 8 for inputting driving force is coaxially arranged at the other end of the rolling brush 1 and the shaft sleeve 2. The last rotation of round brush 1 is connected with rolling bush 3, rolling bush 3 sets up to a plurality of, a plurality of along the circumference annular array of draw-in groove 8 the periphery wall of rolling bush 3 and the internal perisporium roll connection of protection casing 4. The both sides of protection casing 4 are provided with the mounting groove respectively, arbitrary install waterproof strip 5 in the mounting groove.

During operation installs the round brush 1 in protection casing 4 along the one end of rolling bush 3 earlier to be connected its other end and protection casing 4 through detachable connector, go into the both ends card of protection casing 4 after that on the multi-functional brush machine, and with the power input end joint of multi-functional brush machine in draw-in groove 8, install waterproof strip 5 according to the use custom at last in order to prevent splashing of sewage in the one side that is close to the operation personnel.

Above-mentioned mode has simple structure, low in production cost's advantage to waterproof strip 5's the compound ergonomic principle of assembly has better ability that prevents sewage and splash, and whole mechanism dismantles convenient and fast, under the prerequisite that does not change original lithium electricity multi-functional brush, has richened the use scene of brush head greatly.
