The check valve 530 is disposed at the position of the air inlet 511, the central umbrella handle 531 is connected to the upper wall 510 of the water storage tank 500, the skirt 533 is pressed against the inner peripheral wall of the air inlet 511 of the water storage tank with a certain deformation force, and the skirt 533 is engaged with the side wall of the air inlet 511 of the water storage tank. When the air pressure outside the air inlet holes 511 is higher than the air pressure in the reservoir cavity 502 and the deformation force of the skirt 533 is overcome, the one-way valve 530 is opened under the action of the air pressure outside the air inlet holes 511, and the air outside the air inlet holes 511 enters the reservoir cavity 502 through the air inlet holes 511; however, when the air pump 400 stops outputting the pressurized air into the reservoir chamber 502, the skirt 533 will be restored by its own deformation force and fit with the sidewall of the inlet hole 511 of the reservoir, and the check valve 530 is closed to prevent the air in the reservoir chamber 502 from flowing out of the inlet hole 511 in the opposite direction. As shown in fig. 9, the one-way valve 530 is disposed at the outlet 522, the central shaft 531 is connected to the lower wall 520 of the water storage tank, and the peripheral skirt 533 of the umbrella cover 532 presses the outer sidewall of the outlet 522 of the water storage tank with a certain deformation force. When the pressure in the reservoir chamber 502 is greater than the air pressure outside the outlet 522 and the deformation force of the skirt 533 is overcome, the check valve 530 is opened under the pressure of the reservoir chamber 502, the water in the reservoir chamber 502 flows out of the lower wall 520 of the reservoir through the outlet 522, but when the air pump 400 stops outputting the pressurized air into the reservoir chamber 502, the pressure in the reservoir chamber 502 is less than the external air pressure, the skirt 533 is reset by the deformation force and fits the sidewall of the outlet 522 of the reservoir, and the water in the reservoir chamber 502 stops flowing out of the outlet 522. Thus, the technical solution has the beneficial effects that firstly, when the one-way valve 530 is arranged at the position of the air inlet 511, the pressure gas output by the air pump 400 can only enter the water storage cavity 502 from the position of the air inlet 511 under a pressurized state and cannot reversely overflow, so that after the air pump 400 stops outputting the pressure gas, the one-way valve 530 can automatically close the air inlet 511, the space above the liquid level inside the water storage cavity 502 becomes a relatively closed space, and if the liquid continuously seeps out from the water outlet 522 at the moment, the air pressure in the space above the liquid level inside the water storage cavity 502 becomes low, so that the liquid in the water storage cavity 502 is difficult to seep out from the water outlet 522a large amount after the sweeper or the air pump 400 stops working, and the water loss in the water storage tank 500 is reduced; secondly, when the one-way valve 530 is arranged at the position of the water outlet 522, the liquid in the water storage tank 500 can only overflow from the position of the water outlet 522 in a pressurized state, but external air cannot enter the water storage cavity 502, so that after the air pump 400 stops outputting the pressurized air, the one-way valve 530 can automatically close the water outlet 522, the liquid in the water storage cavity 502 is difficult to largely seep out from the water outlet 522, and the water loss in the water storage tank 500 is reduced. In contrast to the prior art, the problem of easy leakage of liquid from the outlet 522 during the shut-down phase is greatly reduced.
By arranging the check valve 530 at the position of the air inlet 511 and the position of the water outlet 522 of the water storage tank, the problem that liquid is easy to leak from the water outlet 522 in the shutdown stage can be greatly reduced in addition to well controlling the water outlet quantity of the water outlet 522 at the lower part of the water storage tank 500 by the air pump 400; therefore, when the sweeper is used for mopping the floor, the pressure gas generated by the air pump 400 is input into the water storage tank 500, and the water in the water storage tank 500 is discharged from the water outlet 522 of the water storage tank, so that the mop 540 can be wetted; also can be in the machine of sweeping the floor shuts down or when air pump 400 is out of work, through atmospheric pressure and the outside atmospheric pressure in the airtight space in the water storage box 500 form the pressure differential, and the deformation effort of check valve 530 makes the delivery port 522 of water storage box is lived well by check valve 530, and the very big reduction is followed the delivery port 522 infiltration of water storage box reduces when the machine of sweeping the floor is out of work the water uptake of mop 540 reduces bacterium on the mop 540 breeds, mop 540 is difficult for erosion too.
Further technical solution, as shown in fig. 4, 6, 10 and 11, the water tank is provided with a guide part 550, and the guide part 550 includes an introduction hole 551, a guide groove 552 and a limit rib 553; the mop 540 is provided with a connecting part 542, a fixing post 541 and a mop body 543, the fixing post 541 and the mop body 543 are respectively fixedly connected to both ends of the connecting part 542, the fixing post 541 is detachably mounted in the guide groove 552, and the guide groove 552 is provided with a notch 554 avoiding the connecting part 542. The guide groove 552 is a groove body having a C-shaped cross section or a shape similar to the C-shaped cross section and disposed on the wall of the water storage tank 500, one end of the guide groove 552 is communicated with the introduction hole 551, and the other end of the guide groove 552 is connected with the limiting rib 553, and the limiting rib 553 can limit the position of the fixing column 541 entering the guide groove 552. The fixed column 541 is a long-strip-shaped column with certain rigidity, the diameter of the fixed column 541 is smaller than that of the guide groove 552, the fixed column 541 can be detachably installed in the guide groove 552, meanwhile, the diameter of the fixed column 541 is larger than the opening size of the notch 554 of the guide groove, and the fixed column 541 cannot be separated from the notch 554 of the guide groove 552; the mop 540 has the advantages that the mop 540 is acted by the transverse friction force parallel to the ground when in use, if the mop 540 is stuck and connected with the mop 540 only by the magic tape 508 arranged at the bottom of the water storage tank 500 like a traditional sweeper, the mop 540 can be displaced or fall off by the transverse friction force when in use, in order to ensure that the mop 540 is better fixed on the water storage tank 500, the guide groove 552 is arranged on the water storage tank 500, the fixing column 541 matched with the guide groove 552 is arranged on the mop 540, and the guide groove 552 can reversely tension the mop 540 when the mop 540 is acted by the transverse friction force, so that the problem of displacement or loosening of the mop 540 is reduced; at the same time, the fixing posts 541 can be removed from the guide slots 552, which facilitates the individual cleaning of the mop 540.
