Set up second tooth comb or brush, the round brush is after the compression roller assembly extrusion is in order to scrape sewage and/or particle filth, the cotton flannel layer of round brush surface absorbs water the lamination and pastes on the roller bearing, the cotton flannel layer that absorbs water that the pressure was pasted continues to rotate forward, when contact with ground once more, because cotton flannel absorbs water the lamination and pastes together, the ability that the round brush adsorbs dirty sewage and/or particle filth can obviously worsen, so after the round brush is extruded through the compression roller assembly, the round brush surface sets up second tooth comb and/or brush with the round brush contact, rack or brush hair scraping cotton flannel layer that absorbs water, make cotton flannel layer that absorbs water become fluffy, and fluffy cotton flannel layer that absorbs water can be fine adsorbs sewage and/or particle filth on ground.

Although the latest floor washing machine in the prior art is called to have a dry and wet sweeping and mopping function, the working principle of the latest floor washing machine generally adopts a scraper blade to scrape water stains on a rolling brush, the 'mopping and drying' effect without the water stains can not be realized actually, dirt and sewage can not be effectively removed, and a product with the function has the advantages of high selling price, complex structural design and easy damage. The wiper blade of these products will form very big resistance if exert great pressure to the round brush, excessively scrape water to damage the round brush body, no matter how big pressure is exerted to the round brush to the wiper blade moreover, can not fully remove water and remove filth, because the wiper blade is one and moves a quiet face contact with the round brush body, frictional resistance is big, and the extrusion efficiency is low, easily hinders scraper blade and round brush, and produces great resistance to the round brush. On the contrary, if the applied pressure is small, the sewage of the rolling brush body can not be effectively removed, so that the rolling brush body is easy to form water stains on the ground. In the patent, on one hand, the spiral bulge of the thread conveying rod and the rolling brush body are adopted for rotary extrusion, and the extrusion force is convenient to adjust, the thread conveying rod and the rolling brush are in relative rotary extrusion of two cylinders, the resistance is small, the extrusion effect is good, water can be extruded more favorably, and peeled dirt can be removed or scraped; on the other hand, further adopt compression roller assembly and round brush to form the relative rotation extrusion of two other cylinders, further extrude the round brush and make water further by the wringing, the certain degree can block large granule filth simultaneously, and is less to the resistance of round brush simultaneously.

The rolling brush is arranged in the driving structure, the structure is compact, the space is saved, the size of the assembly and the equipment can be reduced, the equipment is light, portable and simple, and meanwhile, the production cost can be saved.

When the round brush is dismantled from equipment, built-in drive structure is dismantled along with the round brush is integrative, easy operation, and convenient to use has also avoided the sewage and/or the granule filth on the round brush to drop and has impregnated in the structural circuit short circuit that causes drive structure of drive to damage drive structure simultaneously. The driving structure in the rolling brush is electrically connected to the equipment main body, the structure is simple, the equipment is convenient, the design is ingenious, and the rolling brush is very convenient to detach and install.

The roller brush is characterized in that a dismounting part is arranged at one end of the roller brush, so that the mounting and dismounting of the driving structure in the roller brush are facilitated, in order to avoid the driving structure from contacting water, the dismounting part is provided with a foolproof button, so that the driving structure can be dismounted only when needed, and the driving structure can be moved out of the roller brush only by pressing the button and simultaneously screwing the dismounting part; the push button is stopped or not pressed, the driving structure can not be detached even the dismounting part is screwed, and the driving structure is prevented from accidentally falling out of the rolling brush due to the fact that the dismounting part is mistakenly screwed. The dismounting part also plays a role in supporting the driving structure, the dismounting part is fixedly connected with the driving structure, and the driving structure is fixedly connected to the dismounting part, so that the driving structure can follow the dismounting part and does not rotate along with the rolling brush main body.

The round brush is provided with the dead structure of anti-sticking, and the dead structure of anti-sticking can help the drive structure to continue to rotate when the round brush card is dead unable to rotate, plays the effect of protection motor.

The round brush sets up heat dissipation channel to built-in drive structure, and the heat that produces the built-in motor of round brush can be discharged through heat dissipation channel to the motor cooling, can avoid the too high burning out of motor temperature like this, the motor cooling is favorable to improving the rotational speed of motor shaft simultaneously, improves the clean speed and the clean efficiency of round brush, promotes user satisfaction. Under the normal condition, the built-in motor of the rolling brush generates heat when working, and the heat cannot be removed because the motor is built in the rolling brush, so the rotating speed of the built-in motor of the conventional rolling brush is generally 200-400rpm, if the rotating speed of the motor is increased, the temperature of the motor is too high, the motor is easy to burn out, but the rotating speed of the motor is lower, the cleaning speed is slower, the cleaning efficiency is low, and the requirements of users cannot be met. If the rotating speed of the motor is improved, on one hand, the quality of the motor is improved, for example, an external motor rolling brush is used in a cleaning device in the market, the motor with the rotating speed of 7000rpm is decelerated and adapted to the motor, and the motor is operated at the rotating speed of 1000 rpm; the cleaning equipment with the built-in motor rolling brush is characterized in that the motor with the rotating speed of 7000rpm is reduced to 2400rpm and is adapted to the rolling brush, the two rolling brushes can meet the requirements of users, the motor is a high-quality motor, the cost is too high, the economic burden of the users is increased, and the cleaning equipment is not suitable for vast user groups. Under the condition of not increasing the cost, for the high-speed operation of a common motor, the best method is to use the heat dissipation channel to discharge and reduce the heat generated by the motor and reduce the temperature rise speed of the motor, thereby achieving the purpose of improving the rotating speed of the motor.

The waterproof cover is arranged to prevent water from entering the accommodating cavity of the rolling brush, so that as little water as possible falls onto the water-blocking cotton; the height of the waterproof platform is higher than that of the second end cover, so that the flushing water can be prevented from flowing into the through hole no matter the rolling brush is vertically or horizontally placed.
