Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning, in particular to a multi-passway integrated component for a water tank, a water tank cover and an integrated water tank. BACKGROUND

[0002] Current floor cleaners are generally classified into two branches, i.e., air dust circulation technology represented by a vacuum cleaner and water dust circulation technology represented by a roller-type scrubber. However, due to the limitation of the working principle, the vacuum cleaner cannot clean some garbage and stains firmly attached to the ground. The "water dust circulation" scrubber drives a cleaning cylinder to wipe the ground through the operation of a motor, and the cleaning cylinder usually adopts a sponge cylinder structure. At the same time, the floor cleaner is also equipped with a water supply system and a water tank to clean the cleaning cylinder, thereby perfectly realizing the cleaning of the ground. In order to clean the cleaning cylinder, a closed cleaning space in communication with the water supply system is usually arranged to clean the local roller, clean water is provided to clean the cleaning cylinder, and then the sewage after cleaning the cleaning cylinder is pumped away.

[0003] The water tank of the existing "water dust circulation" scrubber, i.e., the water tank of the new type of sweeping and cleaning integrated tool, usually adopts a split design scheme of a clean water tank and a sewage tank, and also adopts an integrated design scheme of a clean water tank and a sewage tank.

[0004] Chinese patent CN215016831U discloses a water tank of a cleaning device and a cleaning device. The cleaning device includes a machine body, and the water tank includes a clean water tank, a sewage tank, a locking sleeve and a guide cover. The machine body is provided with a water tank mounting groove, and the top end of the water tank mounting groove is provided with a water outlet nozzle. The water tank includes the clean water tank and the sewage tank. The clean water tank is provided with a first water inlet, and the sewage tank is provided with a second water inlet. The clean water tank and the sewage tank are connected through the locking sleeve and are installed in the water tank mounting groove. The guide cover includes a first cover, a second cover and a sliding groove. One end of the sliding groove is connected with the first cover, and the other end is connected with the second cover. The first cover covers the first water inlet, and the second cover covers the second water inlet. The second cover is provided with a water filling port corresponding to the water outlet nozzle. When the water tank is installed, the water outlet nozzle is pressed upward by the sliding groove until the water outlet nozzle corresponds to the water filling port. The water outlet nozzle is embedded in the water filling port, thereby solving the technical problem that the repeated installation process of the water tank causes the installation part of the machine and the water tank to be abraded and the use experience to be poor. The description in paragraph 18 of the specification Figure 1 、 Figure 2 、 Figure 3 It can be seen that the guide cover includes a relatively complex structure to cover the first water inlet and the second water inlet.

[0056] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are meant as examples only and are not intended to limit the present application.

[0057] In a first aspect, as shown in Figures 1-3 , the present application provides a water tank multi-pass combination component 1 for a drag-sweep integrated cleaning tool, which is installed in a water tank cover assembly (not marked in the figure), comprising a T-shaped body 10, on which three mutually independent fluid flow passages (not marked in the figure) respectively composed of six mutually communicating ports (not marked in the figure) are arranged, wherein three ports connected to the outside of the water tank are arranged on the horizontal end face (not marked in the figure) of the T-shaped body, two ports connected to the inside of the water tank are arranged on the downward side of the horizontal end of the body (not marked in the figure), and one port connected to the inside of the water tank is arranged on the downward side of the central vertical end of the T-shaped body (not marked in the figure).

[0058] Specifically, as shown in Figure 1 , Figure 3 , the water tank multi-pass combination component 1 is in the form of a "T" shape, and five ports are arranged on the horizontal end face and the forward side face (which is the downward side face in Figure 1 , which is the forward side face in Figure 3 ) of the "T" shape, and one port is arranged on the central vertical end of the "T" shape. Figure 1 ​Figure 3 The front side (i.e. the side facing forward) is also provided with one through opening.

[0059] Specifically, as shown in Figure 2 , Figure 2 The view angle is the horizontal end of the "T" shape facing forward. The right end of the horizontal end of the "T" shape is provided with an external air extraction opening 11. The side facing downward and perpendicular to the external air extraction opening 11 is provided with an internal air extraction opening 14 with a hole diameter equivalent to that of the external air extraction opening 11. The internal air extraction opening 14 is arranged at the central position of the right end of the horizontal end of the "T" shape. Both the external air extraction opening 11 and the internal air extraction opening 14 are blind holes that do not penetrate the body 10 of the water tank cover six-way piece in the axial direction of the blind hole. Meanwhile, the external air extraction opening 11 and the internal air extraction opening 14 are perpendicular and orthogonal to each other and are connected to each other. The air in the cavity of the sewage tank during the operation of the cleaning tool can be extracted by the internal air extraction opening 14 and then continuously extracted by the air pump along the corresponding pipeline from the external air extraction opening 11 under the operation of the air pump outside the water tank. The left end of the horizontal end of the "T" shape is provided with an external sewage extraction opening 13. The side facing downward and perpendicular to the external sewage extraction opening 13 is provided with an internal sewage inlet 16 with a hole diameter equivalent to that of the external sewage extraction opening 13. The internal sewage inlet 16 is arranged at the central position of the left end of the horizontal end of the "T" shape. Both the external sewage extraction opening 13 and the internal sewage inlet 16 are blind holes that do not penetrate the body 10 of the water tank cover six-way piece in the axial direction of the blind hole. Meanwhile, the external sewage extraction opening 13 and the internal sewage inlet 16 are perpendicular and orthogonal to each other and are connected to each other. During the operation of the cleaning tool, the sewage can be sent into the external sewage extraction opening 13 through the corresponding pipeline under the operation of the air pump outside the water tank, and then the sewage can be continuously sent into the sewage tank along the internal sewage inlet 16 perpendicular to the external sewage extraction opening 13. The central part of the vertical end of the "T" shape is provided with an external clean water extraction opening 12. The side facing downward and perpendicular to the external clean water extraction opening 12 is provided with an internal clean water extraction adapter 15 with a hole diameter equivalent to that of the external clean water extraction opening 12. The internal clean water extraction adapter 15 is arranged at the central position of the vertical end of the "T" shape, as shown in Figure 1 , Figure 3As shown, the plane formed by the axis of the inner sewage inlet 16 and the axis of the inner air outlet 14 is spaced apart from the axis of the inner clear water outlet adapter 15, and a partition (not shown in the figure) is arranged in the water tank body to divide the inner cavity of the water tank into the clear water tank 5 and the sewage tank 6. The partition is arranged between the plane formed by the axis of the inner sewage inlet 16 and the axis of the inner air outlet 14 and the axis of the inner clear water outlet adapter 15. The outer clear water outlet 12 and the inner clear water outlet adapter 15 are both blind holes that do not penetrate the blind hole body 10 of the water tank cover six-way piece, and at the same time, the outer clear water outlet 12 and the inner clear water outlet adapter 15 are perpendicular and orthogonal to each other and are connected to each other. When the cleaning tool is working, the clean water in the clear water tank can be pumped out through the inner clear water outlet adapter 15 and then continuously pumped out through the outer clear water outlet 12 along the corresponding pipeline by the water pump (not shown in the figure) to the water circulation channel (not shown in the figure) of the cleaning tool.

[0060] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 3 The body 10 is also provided with a weight reduction space 105 and a guide fixing hole 17, as shown in Figure 2 From the direction perpendicular to the horizontal end of the "T" shaped horizontal end, the cross section of the weight reduction space 105 occupies most of the area of the horizontal end except the outer air outlet 11, the outer clear water outlet 12 and the outer sewage outlet 13, as shown in Figure 3 The depth of the weight reduction space 105 in the longitudinal direction of the figure occupies more than half of the distance from the horizontal end of the "T" shaped horizontal end to the vertical end, and the weight reduction space 105 is provided with a guide fixing hole 17 at the end of the guide structure in the longitudinal direction of the figure (not shown in the figure), and the guide fixing hole 17 penetrates to the vertical end face of the "T" shaped vertical end, which is beneficial to reduce the overall weight of the body 10. As shown in Figure 1 、 Figure 2 、 Figure 3 The vertical end of the "T" shaped vertical end is also provided with a clear water outlet protruding part 101 and a top surface abutting part 102, and the clear water outlet protruding part 101 is parallel to the plane abutting with the clear water tank of the water tank cover shell 2, and the clear water outlet protruding part 101 is provided with an inner clear water outlet adapter 15, as shown in Figure 7 In this way, the clear water tank clear water outlet protruding part 101 is convenient for directly abutting the inner clear water outlet adapter 15. As shown in Figure 4 As shown in Figure 7As shown in the drawings, the protruding part 101 of the clean water outlet of the clean water tank extends outwardly as a "strip" limiting rib 103 at the arc surface of the limiting lug 22 of the water tank cover shell 2. On one hand, the body 10 can be fixed in the water tank cover shell 2 by the long bolt passing through the guide fixing hole 17. On the other hand, the limiting rib 103 can further match the limiting lug 22 of the water tank cover shell 2, so that when the protruding part 101 of the clean water outlet of the clean water tank directly abuts against the internal clean water outlet adapter 15, the body 10 of the water tank cover six-way fitting is not deformed too much, and the three water or air passages formed by the water tank cover assembly do not leak water or air.

Thus, during the docking process of the three ports on the water tank cover and the corresponding interfaces of the cleaning tool, it can be ensured that the body 10 will not be deformed by external force, so as to ensure that the installed water tank does not leak water or air in the entire water flow passage and air extraction passage of the cleaning tool, thereby ensuring the stable operation of the cleaning tool.

[0062] It should be noted that the body 10 described in the foregoing is not limited to the "T" shape. As long as it is convenient to provide three ports on one end surface, two ports are provided near the end of the side surface perpendicular to the end surface, and one port is provided at the far end of the side surface perpendicular to the end surface, and the three groups of ports are connected to form three independent passages. The body capable of achieving the above structure can also be in the shape of "Y", "L", "V", "U" and "W". The shapes of all bodies capable of achieving the above structure can achieve the above functions under the simple design deformation and adjustment of the skilled person in the art, and are within the protection scope of the present application.

The water tank cover is provided with a sewage tank water inlet, a clean water tank water outlet and a sewage tank air outlet. The water tank cover further comprises the aforementioned water tank cover multi-passage combined component. The water tank cover side cover 3 abuts on one side of the water tank cover multi-passage combined component 1 and installs it into the water tank cover shell 2. The water tank cover bottom cover 4, which is used to seal the water tank opening, is detachably connected to the bottom of the water tank cover shell 2.

[0064] Specifically, as shown in the drawings, Figure 4As shown, the process of installing the body 10 into the water tank cover shell 2 and then covering the water tank cover side cover 3 is as follows: first, the weight-reducing space 105 of the body 10 is sleeved on the positioning mounting column 25, then the positioning mounting column 25 is further guided to penetrate into the guide fixing hole 17 by using the guide structure (not marked in the figure) of the weight-reducing space 105, then the water tank cover side cover 3 is covered, the two abutting ribs 31 of the water tank cover side cover 3 abut on the two abutting surfaces 104 respectively, the vertical end face of the "T" shaped on the body 10 abuts on the inner wall of the water tank cover side cover 3 (not marked in the figure), after the body 10 is installed in place in the water tank cover shell 2, the top surface abutting portion 102 of the body 10 abuts on the inner side top wall 24 of the water tank cover shell 2, the internal air suction port 14 and the internal sewage inlet 16 of the body 10 abut on the inner side of the bottom wall 26 of the water tank cover shell 2, the clean water outlet protruding portion 101 of the body 10 is flat with the outer side of the bottom wall 26 of the water tank cover shell 2, the internal air suction port 14 and the internal sewage inlet 16 match the corresponding internal ports of the water tank cover shell 2 (not marked in the figure), the body 10 itself has a certain elasticity, after being fixed and realizing the matching butt joint of the ports, the abutting surfaces of the body 10 itself can realize that the matched ports do not leak water or air, then the long screw is inserted into the fixing hole 32, the thread on the long screw penetrates through the guide fixing hole 17 and matches with the thread in the positioning mounting column 25 in the water tank cover shell 2, and the installation of the water tank cover assembly is realized by manual fastening.

[0067] In a third aspect, as shown in Figure 10As shown, the water tank cover bottom cover 4 includes a water tank cover bottom cover body 40, a suction pipe 41 extending upward from a through hole (not labeled in the figure) of the water tank cover bottom cover body, and a splash-proof cover (not labeled in the figure) covering the through hole of the water tank cover bottom cover body, the water tank cover bottom cover 4 is provided with a splash-proof isolation mechanism, the splash-proof isolation mechanism includes the splash-proof cover and the suction pipe 41, the side wall and the bottom of the splash-proof cover are screen structures 42.

[0068] As a further improved embodiment, the screen structure 42 includes a planar screen.

[0069] As a further improved embodiment, the screen structure 42 includes a non-planar screen.

[0070] With the smaller holes on the screen structure 42, a water film can be formed by the surface tension of the water, avoiding the clean water from directly passing through the splash-proof isolation mechanism, thereby reaching the pipe formed by the external air suction port 11 and the internal air suction port 14, and avoiding the noise caused by the liquid and air in the exhaust. The screen is made of flexible material, such as gauze, which can better adapt to the change of the liquid level in the clean water tank during use due to its good deformation ability. The extended end of the suction pipe 41 is in elastic interference fit with the internal air suction port 14, and the air drawn by the air pump (not shown in the figure) outside the water tank passes through the sewage tank 6, the screen structure 42, the suction pipe 41, the internal air suction port 14, the external air suction port 11, and then enters the air pump.
