[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the utility model in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation.

[0029] Reference Figures 1 to 6In this embodiment, a water tank assembly is provided, the water tank assembly comprising an integrally formed water tank 20 and a cavity structure, the cavity structure having at least one accommodation space, the water tank 20 being disposed in the accommodation space and detachably mounted in the cavity structure. In this embodiment, the integrally formed structure of the water tank 20 is supported by a blow molding process, and in other specific embodiments, the integrally formed water tank 20 may also be manufactured by processes such as rotational molding or veneer molding.

[0030] Compared with conventional water tank assemblies, the one-piece water tank 20 provided in the present invention has two advantages: the first advantage is that it no longer requires a multi-layer structure to be connected, and the water tank 20 will not leak due to sealing connection problems; the second advantage is that compared with multi-layer structure connections, the production cost of the one-piece water tank assembly is reduced and the manufacturing yield is improved.

[0031] The outside of the water tank 20 is provided with at least one water inlet 21 and at least one water outlet. In the present embodiment, the water tank assembly further includes an air pump 22, and the air outlet end of the air pump 22 is connected to an air inlet pipe 220. An air inlet is also provided on the outside of the water tank 20. The air inlet pipe 220 extends to the inside of the water tank 20 through the air inlet of the water tank 20. A first water outlet pipe 23 is provided at the water outlet, and one end of the first water outlet pipe 23 extends along the water outlet into the liquid in the water tank 20, and the other end of the first water outlet pipe 23 extends to the outside of the water tank 20.

[0032] When water needs to be squeezed out, the air pump 22 is controlled to deliver air into the water tank 20, and the liquid in the water tank 20 will be transported to the outside of the water tank 20 along the water outlet pipe. By controlling the operation of the air pump 22 to achieve uniform water output, the accuracy of the water output is effectively improved.

[0033] In this embodiment, the water outlet and water inlet 21 of the water tank 20 are arranged at the top of the water tank 20. Compared with conventional water tank components, even if the air pump 22 leaks, it is difficult for water to flow out of the water outlet, thereby increasing the anti-leakage effect. Furthermore, a one-way valve 230 is arranged on the first water outlet pipe 23 to prevent siphoning.

[0034] By designing an integrally formed water tank 20 and arranging a cavity structure outside the water tank 20, the impact resistance of the water tank 20 is improved to prevent the water tank 20 from leaking after being impacted. In this embodiment, the cavity structure includes an upper cover 10 and a lower cover 11, and a plurality of limiting columns 110 are arranged on the inner wall of the lower cover 11. A recess 112 is arranged on the outside of the water tank 20 to cooperate with the outer periphery of the limiting columns 110. The water tank 20 can be clamped in the lower cover 11 through the cooperation between the recess 112 and the limiting columns 110, thereby preliminarily limiting the position of the water tank 20.

[0035] The upper cover 10 is provided with an opening 100 and a positioning structure 102. A sealing plug 240 is provided at the top opening 100 of the upper cover 10. A sealing ring 24 is provided between the upper cover 10 and the water tank 20 to fill the gap between the upper cover 10 and the water tank 20 and prevent water from entering the cavity structure. The positioning structure 102 is distributed in a ring shape with the opening 100 as the axis. The positioning structure 102 cooperates with the water injection port 21 to further limit the position of the water tank 20, ensure that the opening 100 of the upper cover 10 is aligned with the water injection port 21 of the water tank 20, and strengthen the sealing effect of the sealing plug 240 on the upper cover 10 on the water injection port 21 of the water tank 20. In this embodiment, a flow channel structure is also provided at the bottom of the lower cover 11. The flow channel structure includes a third through hole 113 provided on the lower cover 11 and a bottom plate 32 connected to the bottom of the lower cover 11. The water outlet is connected to the third through hole 113. A sealing gasket 30 is provided between the lower cover 11 and the bottom plate 32, and the sealing gasket 30 is used to fill the gap between the lower cover 11 and the bottom plate 32, so that the lower cover 11 and the bottom plate 32 form a sealed flow channel space. A groove 320 is provided on the bottom plate 32, and the contour of the groove 320 is adapted to the contour of the sealing gasket 30, and the second through holes 321 are evenly distributed on the groove 320. The side of the bottom plate 32 away from the sealing gasket 30 is used to connect the rag. It can be understood that the water in the water tank 20 will flow along the first water outlet pipe 23, the third through hole 113, and the second through hole 321 to the rag, so that the rag can be evenly wetted.

[0036] Reference Figure 2 As shown in the figure, the lower cover 11 is provided with a partition 111, and the partition 111 divides the space of the inner cavity into a cavity structure for installing the water tank 20 and a dust box cavity 133, and the dust box cavity 133 is used to store garbage absorbed during the sweeping process. A filter assembly 13 is arranged above the dust box cavity 133, and a filter net 131 made of HEPA material is arranged inside the filter assembly 13 to filter dust and debris to prevent them from entering the interior of the sweeper, thereby protecting the normal operation of the sweeper.

[0037] The side of the filter assembly 13 away from the upper cover 10 is hinged to the lower cover 11 through a rotating shaft 134. The side of the filter assembly 13 close to the upper cover 10 is provided with a buckle 130, and the buckle 130 is made of elastic material. The buckle 130 has a protruding structure 132. The side of the upper cover 10 close to the dust box is provided with a buckle 130 connecting groove. Under normal conditions, the protruding structure 132 is confined in the buckle 130 connecting groove; when it is necessary to open the filter assembly 13, the buckle 130 is manually pressed in the direction away from the upper cover 10, and the filter assembly 13 is rotated with the rotating shaft 134 as a support point, so that the filter assembly 13 can be opened to replace the filter screen 131 inside it.

[0038] The utility model also provides a sweeping machine, comprising a sweeping machine body and the water tank assembly mentioned above.

[0039] Example:

[0040] Reference Figure 7 The difference between this embodiment and the embodiment is that a water pump 40 is used to replace the air pump 22, and the pipeline is adjusted at the same time. The advantage of using the water pump 40 is that the water output can be controlled more accurately and evenly.

[0041] Specifically, the water tank assembly also includes a water pump 40, and the water outlet is provided with a second water outlet pipe 41, one end of the second water outlet pipe 41 extends through the water outlet to the liquid in the water tank 20, and the other end of the second water outlet pipe 41 is connected to the water inlet end of the water pump 40, and the water outlet end of the water pump 40 is connected to the third water outlet pipe 42.

[0042] During operation, the water inlet of the water pump 40 draws liquid from the water tank 20 , the third water outlet pipe 42 is connected to the third through hole 113 , and the water outlet of the water pump 40 drains the liquid to the flow channel structure through the third water outlet pipe 42 .
