Description

Dry and wet dual-purpose sewage tank assembly of water machine

Technical Field

The invention relates to the technical field of dust collectors, in particular to a dry and wet sewage tank assembly of a water machine.

Background

The vacuum cleaner can be divided into a vertical type, a horizontal type and a portable type according to the structure. The working principle of the dust collector is that the blades are driven by the motor to rotate at a high speed, air negative pressure is generated in the sealed shell, and dust is sucked. The dust collector mainly comprises three parts of dust generation, dust collection and dust filtration, and generally comprises a series excitation commutator motor, a centrifugal fan, a dust filter (bag) and a dust collection accessory. The power of a typical vacuum cleaner is 400-1000W or more, and the power of a portable vacuum cleaner is 250W or less. The dust collector can remove dust and is mainly characterized in that an electric exhaust fan is arranged at the head of the dust collector. The rotating shaft of the exhaust fan is provided with an air impeller, after the air impeller is electrified, the exhaust fan can generate higher suction force and pressure at the rotating speed of 500 circles per second, air is discharged at high speed under the action of the suction force and the pressure, air in the dust suction part at the front end of the air fan continuously supplements the air in the air fan, instantaneous vacuum is generated inside the dust collector, negative pressure difference is formed between the air and the external atmospheric pressure, and air containing dust is sucked under the action of the negative pressure difference. The dust and other sundries sequentially pass through the carpet or the floor brush, the long connecting pipe, the bent pipe, the hose and the hose joint to enter the dust filtering bag, the dust and other sundries are retained in the dust filtering bag, and the air is purified by the filter disc and then is discharged from the tail part of the machine body.

Although current dust catcher has wet dust catcher futilely, current wet dust catcher always all is to dissolve dry rubbish in aqueous and operate, current wet dust catcher futilely also all is the design of tubbiness formula, not only the structure is complicated, whole device is also comparatively huge moreover, it also needs increase operating personnel's labour when the operation simultaneously, make the operation of being not convenient for on the one hand of dust catcher, on the other hand because wet rubbish mixes together futilely, lead to unable effectual separation, it is clean also inconvenient.
