Further, a drainage opening 1851 is formed on the sidewall of the drainage tube 185, so that the air flow can communicate with the water inlet tube 152 through the drainage opening 1851.

Further, the side wall of the filter cartridge 184 is provided with a plurality of filter holes, so that the dirt in the shape of lint can be blocked by the filter holes, and can slide into the cup 151 along with the accumulated dirt, and finally be collected by the cup 151.

Referring to fig. 9 and 10, a detailed structure of the draft tube 185 is shown in detail, specifically, the draft tube 185 includes a starting section 185a and a terminating section 185c, and a roundabout section 185b integrally formed between the starting section 185a and the terminating section 185c, wherein a radius of curvature of the roundabout section 185b is gradually increased in a direction in which the starting section 185a extends to the terminating section 185c, and the drainage port 1851 is opened between the starting section 185a and the terminating section 185 c.

Referring again to fig. 8 and 10, the end of the initial segment 185a is integrally formed with a guide segment 185d tangent to the initial segment 185a so that the air outlet direction of the drain 1851 coincides with the end tangent direction of the bypass segment 185b, and with this structure, the dirty water/air mixture fluid entering the drain 185 through the inlet pipe 152 in the direction of the arrow a can be forced to follow a spiral path along the bypass segment 185b and finally be discharged from the drain 1851.

Further, the outer diameters of the water inlet pipe 152 and the draft pipe 185 are smaller than the inner diameter of the water-gas separation cylinder 183, and the outer wall of the water inlet pipe 152 is spaced apart from the inner wall of the water-gas separation cylinder 183 to form a water falling channel therebetween, so that the dirty water/air mixture fluid guided out of the drainage port 1851 can fall down from the drainage port 1851 along the water falling channel (the arrow B is shown).

Referring to fig. 8, fig. 8 shows a configuration diagram of the water suction brush in a use state, when the water suction brush is in use, an included angle γ is formed between an axis of the water inlet pipe 152 and a horizontal plane, and the included angle γ can be changed between 5 ° to 90 ° according to the use state of an operator, in the use state shown in fig. 8, the dirty water/air mixed fluid guided out from the drainage port 1851 can fall down along the water falling channel from the drainage port 1851, then the dirty water on the lower side in the water inlet pipe 152 falls into the cup 151 along the arrow D direction, while the dirty water on the upper side in the water inlet pipe 152 clings to the outer sidewall of the water inlet pipe 152 to fall into the cup 151 along the arrow E direction, since the density of the air and the flocculent dirt is much less than that of the water, after being sucked by the suction pipe 182, the air guided out from the water falling channel is discharged upwards along the arrow C direction, and the flocculent dirt is isolated outside the outer wall of the, the filtered air passes through the filter cartridge 184 and is exhausted through the exhaust tube 182 in the direction of arrow F, thereby completing the water-gas separation process.

In a preferred embodiment, the inner diameter of the inlet pipe 152 corresponds to the minimum radius of curvature of the roundabout segment 185 b.

The working principle is as follows:

referring to fig. 15, the mixed sewage-air fluid is sucked from the gap at the bottom of the water suction guide plate 1322, divided and guided by the guide vertical plate 1315, enters the water suction channel 172 along the arrow S direction, converges to the center of the water suction channel 172 in the water suction channel 172 along the arrow M and arrow N directions, and is introduced into the filter channel 173, and the mixed sewage-air fluid is finally sucked by the water suction pipe 161 after being filtered by the filter unit 114 in the filter channel 173;

referring to fig. 8 and 10, the suction pipe 161 is connected to the inlet pipe 152, so that the sucked sewage air mixed fluid can enter the draft tube 185 through the inlet pipe 152 in the direction of arrow a, and then the sewage air mixed fluid is forced to follow a spiral path along the roundabout segment 185B and finally guided out from the drainage port 1851, and the sewage air mixed fluid guided out from the drainage port 1851 can fall downwards from the drainage port 1851 along the downpipe channel (the arrow B is shown);

referring to fig. 8, fig. 8 shows a configuration diagram of the posture of the water suction brush in the use state, when the water suction brush is in use, an included angle γ is formed between the axis of the water inlet pipe 152 and the horizontal plane, and the included angle γ can be changed between 5 ° and 90 ° with the use state of an operator, in the use state shown in fig. 8, the sewage-air mixed fluid led out from the drainage port 1851 can fall down from the drainage port 1851 along the water falling channel, then the dirty water on the lower side in the water inlet pipe 152 falls into the cup 151 along the arrow D direction, while the dirty water on the upper side in the water inlet pipe 152 clings to the outer side wall of the water inlet pipe 152 and falls into the cup 151 along the arrow E direction, since the density of the air and the flocculent dirt is much less than that of the water, after being sucked by the suction pipe 182, the air led out from the water falling channel upwards along the arrow C direction, and the flocculent dirt is isolated outside the outer wall, the filtered air passes through the filter cartridge 184 and is discharged through the exhaust tube 182 in the direction of arrow F, thus completing the water-gas separation process; subsequently, the sewage collected by the water collecting cup 15 can be discharged into the water storage tank 12 through the water discharge pipe 163, and the air pressure balance between the water storage tank 12 and the water collecting cup 15 is maintained by the air guide pipe 162; when the water level detection unit in the water collecting cup 15 detects that the inner space of the water storage tank 12 is full, a water tank full signal is sent to the machine body, the machine body sends out a preset warning buzzer to remind a user to shut down and clean the water storage tank 12 in time.
