The operating principle of the water pumping device 20 in this embodiment is: the water pumping device 20 is similar to the operation principle of the centrifugal pump in the prior art, and works by utilizing the centrifugal force generated by water due to the rotation of the impeller 22, before the water pumping device 20 is started, the pump shell 21 and the water pumping part 23 are filled with water, then the rotating shaft drives the impeller 22 and the water to do high-speed rotation motion, the water is thrown to the outer edge of the impeller 22 under the action of the centrifugal force and enters the water outlet part 24 of the water pumping device 20 through the pipeline of the pump shell 21, the center of the impeller 22 of the water pumping device 20 is vacuumized after being thrown out under the action of the centrifugal force, the water outside the water pumping part 23 is pressed into the pump shell 21 under the action of atmospheric pressure, and the impeller 22 continuously rotates to enable the water to continuously flow in and out under the action of the impeller 22, so that the purpose of conveying the water is achieved. Therefore, in the embodiment, in order to ensure that the water pumping function of the water pumping device 20 is continuously effective, it is required to ensure that the clear water can always submerge the water pumping part 23. Due to the adoption of the water storage device of the mop bucket, water can be supplied to the water pumping device 20 for a long time so as to meet the vacuum requirement of the water pumping device 20, and the water pumping function of the water pumping device 20 is continuously effective.

As mentioned above, according to the operation principle of the water pumping device 20, water is thrown to the outer edge of the impeller 22 by the centrifugal force and flows out through the water outlet portion 24 of the pump housing 21, the clear water flies out along the tangential direction of the circumference at the moment of being thrown out, in order to guide the clear water upwards and reduce the frictional resistance of the clear water in the water outlet portion 24, the water outlet portion 24 is designed to be an upward arc-shaped structure, the water outlet portion 24 is communicated with the water spray head 32 through the water pipe 25, and the outflowing clear water is ejected from the water spray head 32 after passing through the water outlet portion 24 and the water pipe 25 in sequence.

As shown in fig. 6 and 7, in one embodiment, the water pumping device 20 includes a pump casing 21 and an impeller 22, the impeller 22 is located in the pump casing 21 and is rotatably connected to the pump casing 21; the impeller 22 has blades 221, and the lower edges of the blades 221 are inclined upward as being away from the rotation axis of the impeller 22; the surface of the pump casing 21 opposite to the lower edge of the vane 221 is also inclined upward.

According to the operation principle of the water pumping device 20, water is thrown to the outer edge of the impeller 22 under the action of centrifugal force and flows out through the water outlet portion 24 of the pump shell 21, so that the contact area between the outer edge of the impeller 22 and clean water directly determines the adhesion between clean water and the impeller 22 and the difficulty of throwing the clean water out, the smaller the contact area is, the smaller the adhesion of the clean water is, i.e. the clean water is more easily thrown out by the impeller 22, and meanwhile, the problem of guiding after the clean water is thrown out is also considered, i.e. the clean water is required to flow into the inner cavity of the barrel 30 above after being pumped out.

In summary, the lower edge of the blade 221 of the impeller 22 is inclined upward as being away from the rotation axis of the impeller 22, the cross section of the end of the blade 221 is gradually reduced, so that the contact area between the blade 221 and the clean water is correspondingly reduced, the adhesion force of the clean water to the blade 221 is smaller, the clean water is more easily thrown upward, and the working efficiency of the water pumping device 20 is improved.

As shown in fig. 3, 4, and 6, in one embodiment, the impeller 22 is mounted inside the pump housing 21 by a support shaft 222. The support shaft 222 is fixed in the pump housing 21, and the center of the impeller 22 overlaps the top end of the support shaft 222. Preferably, a ball is further provided between the impeller 22 and the support shaft 222 to reduce the rotational resistance between the impeller 22 and the support shaft 222.

As shown in fig. 3, 4, and 6, in one embodiment, the pump casing 21 includes an upper pump casing 211 and a lower pump casing 212, and the upper pump casing 211 is butted against the lower pump casing 212. The corresponding positions of the upper pump shell 211 and the lower pump shell 212 are provided with a buckle and a clamping groove, so that the upper pump shell 211 and the lower pump shell 212 can be quickly assembled and connected.

Optionally, the upper pump casing 211 and the lower pump casing 212 may also be connected by a socket structure, bonded by an adhesive, or the like.

As described above, the first water storage chamber 11 is connected to the water storage tank 31 or an external water pipe through the water inlet 111, and for convenience of use, it is preferable that the tub 30 is provided with the water storage tank 31 and the water storage tank 31 is communicated with the water inlet 111.

Before a user uses the water storage tank 31, clear water is added into the water storage tank 31, and according to the principle of the communicating vessel, the clear water in the water storage tank 31 can continuously flow into the first water storage cavity 11 and the second water storage cavity 12, so that the water levels of the water storage tank 31 and the second water storage cavity 12 are finally consistent. Therefore, when the storage tank 31 is fully loaded, it can naturally flow into the second storage chamber 12 by the action of potential energy to supply water.

As shown in fig. 3, in an embodiment, the first water storage chamber 11 includes an inner water tank 112, the inner water tank 112 is disposed between the water storage tank 31 and the water guide 40 in a communicating manner, and the inner water tank 112 is lower than the position where the water spraying head 32 is disposed, so that the water in the water storage tank 31 flows into the water guide 40 and the second water storage chamber 12 through the inner water tank 112.

In the prior art, the sprinkler head 32 is usually disposed at the middle-lower part or the bottom of the inner cavity of the barrel 30, and the purpose thereof is two-fold: firstly, the distance between the water pumping device 20 and the water spraying head 32 can be shortened, so that the requirement on the stroke of the water pumping device 20 is reduced, secondly, the dirtiest position of the mop head is usually at the lower part, and the water spraying head 32 is arranged at the middle lower part or the bottom of the cavity in the barrel body 30, so that the washing pertinence is stronger.

As mentioned above, the sprinkler head 32 is usually located at the middle-lower portion or bottom of the cavity inside the tub 30, so that the sprinkler head 32 is generally located below the highest water level of the storage tank 31, and when the amount of fresh water in the storage tank 31 is large, the fresh water in the storage tank 31 will naturally flow to the sprinkler head 32 even if the water pumping device 20 is not actuated. When the water storage tank 31 is filled with clear water, the potential energy of the clear water is so large that the clear water can overflow from the sprinkler head 32 quickly, so that the user does not start to rotate the water pumping device 20 to perform the water pumping and flushing functions, the clear water in the water storage tank 31 begins to run off, and further the clear water needs to be replenished into the water storage tank 31 repeatedly, and the user experience degree in the whole operation process is poor.

In view of the above, the inner water tank 112 is additionally provided in the first water storage chamber 11, the inner water tank 112 is disposed between the water storage tank 31 and the water guide 40, and the inner water tank 112 is lower than the position where the sprinkler head 32 is disposed, so that the clean water in the water storage tank 31 does not directly flow to the second water storage chamber 12, the water pumping device 20, or even flow out of the sprinkler head 32, but first flows into the inner water tank 112 to reduce the potential energy of the clean water, then slowly flows into the second water storage chamber 12, is pumped out by the water pumping device 20, and is then sprayed out through the sprinkler head 32. The potential energy of clear water in the storage water tank 31 can be adjusted to the interior water tank 112 that adds, avoids the clear water in the storage water tank 31 to spill over from sprinkler bead 32 rapidly, compares prior art, can reduce the user to the moisturizing number of times of storage water tank 31, improves user experience.
