Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning tools, and in particular to a single-pipe water pump. Background Technology
[0002] In the market, cleaning flat mops generally involves stirring them in a bucket of clean water or spraying them directly from a tap. Alternatively, some mops use a spray mechanism installed inside the mop bucket. This type of spray mechanism often uses a piston structure to draw water out for spraying. However, current piston structures typically have two pipes: one for the water flow and the other for the piston's movement. Such structures are relatively large, requiring a large installation space for the mop bucket and incurring high costs. Summary of the Invention
[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0004] A single-tube water pump has a water storage section between the inlet and outlet sections, and a drive unit is installed in the water storage section. The drive unit draws water from the inlet section into the water storage section and sprays it out from the outlet section.
[0005] The water inlet includes a first one-way valve body, which allows water from the water inlet to flow inward to the water storage section;
[0006] The drive unit includes a piston disposed in the water storage section. The piston has a cavity, and the cavity is provided with a first through hole and a second through hole. A second one-way valve body is disposed in the cavity. The second one-way valve body allows the water flow from the water storage section to flow to the water outlet section through the first through hole and the second through hole.
[0007] Furthermore, the water inlet also includes an inlet and an outlet, with the first one-way valve body located between the inlet and the outlet.
[0008] Furthermore, the first one-way valve body is a first ball, which moves up and down within the outlet. When the first ball moves upward, the outlet opens; when the first ball moves downward, the outlet closes.
[0009] Furthermore, the second one-way valve body is a second ball, which moves upward / downward within the piston. When the second ball moves upward, the second through hole opens, and when the second ball moves downward, the second through hole closes.
[0010] Furthermore, the water storage section is provided with a cavity, one end of which is connected to the water inlet section and the other end of which is connected to the water outlet section.
[0011] Furthermore, the drive unit also includes a connecting rod and a drive member disposed within the cavity. One end of the connecting rod is rotatably connected to the piston, and the other end is rotatably connected to the drive member. Rotating the drive member can drive the piston to move upward / downward within the cavity.
[0012] Furthermore, a partition is provided inside the water storage section, and the partition is located between the water inlet section and the water storage section.
[0013] Furthermore, the driving component includes a rocker arm and a driving gear. The rocker arm is rotatably connected to the connecting rod. When the driving gear rotates, it can drive the rocker arm to move the piston.
[0014] The beneficial effects of this utility model are:
[0015] When the piston moves upward, the second ball is pressed downward, closing the second through hole. The first ball moves upward, and water flows into the water storage section. When the first ball moves upward, the outlet opens. When the piston moves downward, the first ball is pressed downward, closing the outlet. The second ball moves upward, opening the second through hole. Water in the water storage section flows out from the second and first through holes to the outlet. This invention only requires one pipe to complete the pumping function, reducing the overall structure of the water pump, saving installation space, and saving costs. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Specific Implementation Example 1:
[0026] A single-tube water pump includes an inlet section 1 and an outlet section 4. The pump is characterized in that a water storage section 2 is provided between the inlet section 1 and the outlet section 4, and a drive unit 3 is installed within the water storage section 2. The drive unit 3 draws water from the inlet section 1 into the water storage section 2 and sprays it out from the outlet section 4. Preferably, the water storage section 2 is a cavity, with one end connected to the inlet section 1 and the other end connected to the outlet section 4. A partition 21 is also provided within the water storage section 2, located between the inlet section 1 and the water storage section 2.
[0027] Specifically, the water inlet 1 includes an inlet 11 and an outlet 12. A first ball 13 is provided at the outlet 12. The first ball 13 moves up and down inside the outlet. When the first ball 13 moves upward, the outlet 12 opens. When the first ball 13 moves downward, the outlet 12 closes.
[0028] It is understood that the driving unit 3 includes a piston 31, a connecting rod 32, and a driving member 33 disposed within the cavity. One end of the connecting rod 32 is rotatably connected to the piston 31, and the other end is rotatably connected to the driving member 33. Rotating the driving member 33 can drive the piston 31 to move upward / downward within the cavity. Optionally, the piston 31 has a cavity with a first through hole 311 and a second through hole 312. A second ball 34 is disposed within the cavity. The second ball 34 moves upward / downward within the piston 31. When the second ball 34 moves upward, the second through hole 312 opens; when the second ball 34 moves downward, the second through hole 312 closes. Preferably, the driving member 33 includes a rocker arm 331 and a driving gear 332. The rocker arm 331 is rotatably connected to the connecting rod 32. When the driving gear 332 rotates, it can drive the rocker arm 331 to move the piston 31.
