Description

Water-absorbing brush with water-gas separation structure and its water-absorbing structure

Technical field

The invention relates to the field of small household appliances, and in particular to a water-absorbing brush with a water-gas separation structure and a water-absorbing structure thereof.

Background technique

In the field of vacuum cleaners, it is well known to use suction brushes of different structures to suck and remove sewage in the target area. In the process of researching and realizing sewage absorption and removal, the inventor found that the water absorption brush in the prior art has at least the following problems:

First of all, the water-gas separation rate is low, resulting in that there is still water being taken out at the air outlet, which causes the subsequent parts to be contaminated by sewage or even the risk of motor short-circuit due to seepage; secondly, the traditional water suction brush tank is usually put At the handle part of the suction brush, since the dirt absorbed and removed by the suction brush is liquid, this layout easily causes the user to operate the suction brush due to the large sloshing and floating of the sewage in the water tank, which causes the sewage to dump and overflow, which intensifies other parts. Risk of being polluted by sewage and short circuit of the motor due to seepage; finally, in the process of water absorption, the cotton wool and other dirt mixed in the sewage will be sucked by the suction brush along with the sewage. As the number of uses increases, the dirt is likely to be in the pipe. Enrichment in the road leads to increasingly narrower pipe diameters, which in turn leads to insufficient suction of the suction brush and even pipeline blockage.

In view of this, it is necessary to develop a water-absorbing brush with a water-gas separation structure to solve the above-mentioned problems.

And finally lead out from the drainage port 1851.

Further, the outer diameters of the water inlet pipe 152 and the drainage pipe 185 are both smaller than the inner diameter of the water-gas separator cylinder 183, and the outer wall of the water inlet pipe 152 and the inner wall of the water-gas separator cylinder 183 are spaced apart to form The falling water channel between the two, so that the dirty water/air mixed fluid derived from the drainage port 1851 can fall down from the drainage port 1851 along the falling water channel (the arrow B shown in the figure).

Referring to Figure 8, Figure 8 shows the posture structure diagram of the suction brush in use. When the suction brush is in use, the included angle γ between the axis of the water inlet pipe 152 and the horizontal plane is formed. Generally, the included angle γ can follow the operator's use The state changes between 5° and 90°. In the use state shown in Figure 8, the dirty water/air mixed fluid derived from the drainage port 1851 can fall down from the drainage port 1851 along the falling channel. Then, the dirty water on the lower side of the inlet pipe 152 falls into the cup 151 along the direction of arrow D, and the dirty water on the upper side of the inlet pipe 152 falls into the outer wall of the inlet pipe 152 along the direction of arrow E. In the cup 151, the density of air and flocculent dirt is much lower than that of water. After being sucked by the suction pipe 182, the air drawn from the falling water channel is discharged upward along the direction of arrow C, and the flocculent dirt passes through The filter cartridge 184 is isolated from the outer wall of the filter cartridge 184 after filtration, and the filtered air passes through the filter cartridge 184 and is discharged in the direction of arrow F through the suction pipe 182, thus completing the water-gas separation process.

In the use state as shown in Figure 8, the sewage-air mixed fluid derived from the drainage port 1851 can fall down from the drainage port 1851 along the falling channel. Then the dirty water on the lower side of the water inlet pipe 152 falls into the cup 151 along the arrow D direction, while the dirty water on the upper side of the water inlet pipe 152 falls into the cup body along the arrow E direction against the outer side wall of the water inlet pipe 152 In 151, the density of air and flocculent dirt is much lower than that of water. After being sucked by the suction pipe 182, the air drawn from the falling water channel is discharged upward along the direction of arrow C, and the flocculent dirt passes through the filter cartridge. After the 184 is filtered, it is isolated outside the outer wall of the filter cartridge 184, and the filtered air passes through the filter cartridge 184 and is discharged through the suction pipe 182 in the direction of arrow F. This completes the water-gas separation process; 15 The collected sewage can be discharged into the water storage tank 12 through the drain pipe 163, and the air pressure balance in the water storage tank 12 and the water collection cup 15 is maintained by the air duct 162; when the water level detection unit in the water collection cup 15 detects the water storage tank 12 When the internal space is almost full, the water tank is full signal is sent to the body, and the body emits a preset warning buzzer to remind the user to shut down and clean the water tank 12 in time.
