Description

Technical Field

[0001] The present invention relates to the field of cleaning machines, and more particularly, to a water tank filling device and a cleaning machine for a cleaning machine. Background Art

[0002] Cleaning machines applied to home environments, office environments or industrial environments mainly use water as a cleaning medium to perform cleaning operations on floors or walls, such as carpet cleaning machines.

[0003] Currently, the water injection structure on cleaning equipment such as carpet cleaning machines is usually achieved through electromagnetic or mechanical valves. The solenoid valve is convenient to use but has a high cost and has the defect of complex internal wiring. The traditional water injection valve is often controlled by a switch similar to a faucet or a foot pedal. Since it cannot be operated during the pushing process, it brings great inconvenience to users during use. Summary of the Invention

[0004] In view of this, the present invention provides a water tank filling device and a cleaning machine for a cleaning machine, which can effectively solve the problems of high cost and inconvenient use of the water injection structure in the prior art.

[0005] On the one hand, the present invention provides a water tank filling device for a cleaning machine, which includes a water injection tank communicated with the water tank. The water injection end of the water injection tank is connected to a water injection pipe. A movable sealing member is provided at the connection between the water injection end and the water injection pipe. The sealing member has a first sealing convex edge for sealing the connection. The first sealing convex edge contacts or is connected to a pushing member, and the pushing member pushes the sealing member to move in the direction of the water injection pipe.

[0006] Further, the above-mentioned sealing member includes a sealing valve stem, and the first sealing convex edge is arranged along the circumferential direction of the sealing valve stem.

[0007] Further, the surface of the first sealing convex edge is provided with a second sealing convex edge arranged along the circumferential direction of the first sealing convex edge.

[0008] Further, a stepped surface structure is formed between the second sealing convex edge and the first sealing convex edge, and the connection has a stepped surface matching the stepped surface structure.

[0009] Further, the bottom of the second sealing convex edge forms a conical end.

[0010] Further, the top of the sealing valve stem has an umbrella cover member, and the top of the umbrella cover member contacts or is connected to the pushing member.

[0011] Further, the top of the umbrella cover member is provided with a convex platform, which contacts or is connected to the pushing member.

[0012] Further, the above-mentioned pushing component is connected to the handle trigger of the cleaning machine.

[0013] Further, the above-mentioned pushing component is a push rod.

[0014] On the other hand, the present invention provides a cleaning machine, including a cleaning machine main body, characterized in that it further includes a water tank filling device for a cleaning machine as described above.

[0015] When the water tank filling device for a cleaning machine and the cleaning machine provided by the present invention are working, the water in the water tank is injected into the water injection tank. Since a movable sealing component is arranged inside the connection part between the water injection end and the water injection pipe, when the sealing component is not pushed by the pushing component, the first sealing convex edge seals the connection part. When the sealing component is pushed by the pushing component, the first sealing convex edge moves downward, and a gap between the connection part and the sealing component leaks out, and the water flows into the water injection pipe under the action of gravity, thereby realizing the water injection function. Therefore, the water injection function can be realized through a simple pushing action, effectively solving the problems of high cost and inconvenient use of the water injection structure in the prior art.

Embodiment 1:

[0020] See Figures 1 to 2, The figure shows a water tank filling device of a cleaning machine provided in the first embodiment of the present invention, which includes a water injection tank 1, which is communicated with a water tank 2. The water injection end 11 of the water injection tank 1 is connected to a water injection pipe 12. A movable sealing member 13 is provided at the connection 111 between the water injection end 11 and the water injection pipe 12. The sealing member 13 has a first sealing convex edge 131 that seals the connection 111. The first sealing convex edge 131 contacts or is connected to a pushing member 14. The pushing member 14 can specifically be a push rod, and the pushing member 14 pushes the sealing member 13 to move in the direction of the water injection pipe 12. Among them, a valve member can be provided between the water injection tank 1 and the water tank 2 to achieve a quantitative water output.

[0021] Continue to refer to Figures 1 to 2 , Specifically, the sealing member 13 includes a sealing valve stem 132, and the first sealing convex edge 131 is arranged along the circumferential direction of the sealing valve stem 132.

[0023] For the water tank filling device of a cleaning machine and the cleaning machine provided in this embodiment, during operation, the water in the water tank is injected into the water injection tank. Since a movable sealing member is provided inside the connection between the water injection end and the water injection pipe, when the sealing member is not pushed by the pushing member, the first sealing convex edge seals the connection. When the sealing member is pushed by the pushing member, the first sealing convex edge moves downward, and a gap between the connection and the sealing member leaks out. Under the action of gravity, the water flows into the water injection pipe, thereby realizing the water filling function. Therefore, the water filling function can be realized through a simple pushing action, effectively solving the problems of high cost and inconvenient use of the water filling structure in the prior art.
