Compared with the prior art, the technical scheme of the patent has at least one or more of the following beneficial effects:

the screw assembly is tightly attached to the rolling brush body through the dirt receiving opening, a negative pressure area is formed in the dirt containing groove in the rotation process of the rolling brush body and the screw assembly, and the screw assembly extrudes water and dirt on the rolling brush body into the dirt containing groove. Because the screw assembly is provided with the screw assembly with the rotating direction and the screw assembly is matched with the sewage containing groove, the screw assembly can drive water, sewage and gas in the sewage containing groove to be conveyed to the sewage outlet, and then the sewage is thrown into the sewage cavity (namely the first accommodating cavity) through the second screw assembly in a high-speed rotation mode. When the water, dirt and gas in the dirt holding tank are conveyed to the sewage outlet, negative pressure is formed in the dirt holding tank, and the water, dirt and air which are cleaned by rolling of the rolling brush assembly can be supplemented into the negative pressure area, so that the rolling brush assembly circulates circumferentially. After sewage dirt and gas enter the sewage cavity, the volume in the sewage cavity can be occupied, and air in the sewage cavity needs to be discharged, so that the sewage dirt and gas can continuously enter the sewage tank. Therefore, an air hole is needed to be opened on the sewage cavity shell. Otherwise, if the pressure of the gas in the sewage cavity is not released, the water, dirt and gas in the sewage containing tank cannot continuously enter the sewage cavity, so that a large amount of water leakage of the cleaning equipment is caused.

The sewage cover component is provided with air holes, and after water, dirt and gas in the sewage containing groove enter the sewage cavity, the gas in the sewage cavity is discharged through the air holes so as to balance the air pressure inside and outside the sewage cavity.

The inner wall of the sewage cover component is provided with a shielding groove, so that the effects of blocking the ventilation holes and sewage and dirt are achieved, the ventilation holes are prevented from being blocked by the sewage and dirt surging in the sewage cavity or the sewage and dirt in the sewage cavity is prevented from being thrown into the sewage cavity from a sewage outlet, the air in the sewage cavity cannot be discharged, the air pressure in the sewage cavity cannot be released, and the sewage and dirt overflows from the ventilation holes. The shielding groove is internally provided with water-blocking cotton, so that the surge prevention effect is better, and dirt can be prevented from overflowing from the ventilation holes.

The rolling brush assembly is sleeved on the motor assembly, the motor assembly drives the rolling brush assembly to rotate through the rotary joint and the mounting groove, the motor assembly is fixedly mounted on the equipment main body, and the motor assembly is not detached along with the rolling brush assembly when the rolling brush assembly is detached, so that the rolling brush assembly is simple in structural design, convenient to detach and easy to operate. Set up on the swivel joint with mounting groove assorted sand grip, the length direction of sand grip is less than 90 degrees with the length direction's of round brush subassembly contained angle, follows the sand grip is close to driving motor's one end to the sand grip is kept away from driving motor's one end direction, the sand grip inclines towards the direction of rotation when round brush subassembly advances to when cleaning equipment used, the round brush subassembly forwards rotates, has the power towards motor subassembly direction when the round brush body is rotatory, makes the round brush body locate on the motor subassembly more closely when rotatory, in order to ensure that the round brush subassembly can not take off from the equipment main part loose when equipment uses. Meanwhile, one end of the rolling brush component far away from the motor component is magnetically adsorbed on the equipment main body, so that the rolling brush is convenient to detach and install, labor-saving and particularly suitable for female users with weak strength.

The mounting structure is arranged at the sewage port, so that the sewage outlet and the sewage port can be firmly and tightly fastened together, and sewage and dirt leakage cannot occur. Compared with the mounting structure which is not arranged at the sewage port, if the water tank shakes on the equipment, gaps appear between the sewage port and the sewage port, and sewage and dirt leakage is easy to cause.

The existing two-in-one water tank is few, and the water tank is bigger, so that the water tank is inconvenient to use by people if bigger, and the volume of the water tank is reduced as much as possible by designing a unique partition plate, so that the space is saved. When the water tank and the cleaning module are horizontally placed, the sewage outlet of the sewage cavity is connected with the sewage outlet of the cleaning module, and the sewage outlet of the sewage cavity is arranged on the side wall of the sewage cavity, so that the sewage cavity can only utilize the volume space below the sewage outlet when sewage is collected, and the volume space above the sewage outlet is wasted. Or the sewage port is arranged at the upper part of the sewage cavity through special design so as to fully utilize the volume of the sewage cavity, otherwise, the screw rod component is utilized to throw out sewage and dirt, the lift can only throw half because of natural throwing force, and the space above the sewage port is wasted. In view of the above, the space on the upper part of the sewage cavity is set to be the clean water cavity by adopting the unique partition board, and the advantage of the arrangement is that the design of a complex sewage structure is not needed, and sewage and dirt can be thrown into the sewage cavity only by utilizing the lift naturally thrown out by the screw assembly. In addition, the upper half part of the sewage cavity is divided into a two-component clean water cavity (namely a second accommodating cavity) and a sewage cavity (namely a first accommodating cavity) through a unique curved surface or inclined surface baffle plate, the clean water cavity can be directly connected with the equipment main body, the clean water pipeline of the clean water cavity is short, the structure of the whole cleaning equipment is simpler, and water in the clean water cavity is pumped through a pumping device to supply water for the surface of the rolling brush. Through above design, the ingenious place of this equipment lies in, and clean module gets rid of sewage filth into the sewage chamber through the lift that screw assembly drove, need not to additionally provide the drive, but because natural lift is limited, drain and sewage mouth's height is lower, so utilizes unique baffle to cut apart sewage chamber upper portion into the clean water chamber to make full use of water tank volume. The unique cleaning module is isolated from the unique partition of the water tank, so that the water tank can be fully utilized.

Most cleaning equipment's water tank all sets up on the action bars, can make the action bars thick heavy like this, and this patent's water tank sets up on equipment main part, and on the non-action bars, like this the water tank can promote the water yield under the certain circumstances, more importantly structural design is simple, has saved the drive component that is used for the blowdown, and the energy consumption is lower.

If this patent on two unification water tanks match other similar dust collectors or floor cleaning machines, unlike the water tank of this patent and the clean module's that has screw assembly degree of fit higher, this patent clean module as long as drive round brush drive part can, the screw assembly of in close contact on the round brush can follow round brush rotation, screw assembly rotation can drive sewage filth and carry to the drain, and screw assembly rotates and produce centrifugal force, produce the lift under centrifugal force effect, sewage filth gets rid of into the sewage intracavity through the lift, this kind of blowdown mode is extremely simple, save the cost, it is simple high-efficient again, through unique baffle design make full use of water tank inner space, above-mentioned characteristic combines together, screw assembly blowdown mode and water tank design mode, for the prior art has constituted obvious innovation, unexpected effect is produced, unexpected effect has further reduced the complexity of cleaning equipment structure, simultaneously can maintain clean efficiency again, reduce product cost, promote user experience.

The water tank is further preferably designed into a cup shape, the ports of the sewage cover assembly and the clear water cover assembly are designed into a round shape, the sewage cover assembly and the clear water cover assembly can be sealed by using the round sealing ring, the sealing effect of the round sealing ring is better relative to the sealing rings in other shapes, the service life is longer, and meanwhile, the price of the round sealing ring is cheaper compared with that of the sealing rings in other shapes.
