Description

Technical Field

[0001] The utility model relates to the technical field of water pumps, and mainly relates to a micro water pump capable of sustainable water supply. Background Art

[0002] At present, the water inlet and outlet of some water pumps are both set at the top. The water flows downward first and then upward. When flowing downward, the pressure will increase under the action of gravity, and long-term use will have an impact on the pressure regulating parts; the distance between the water outlet and the water inlet of most water pumps is relatively close, and the space available for the installation of the designed fluid channel, pressure regulating structure, etc. between the two is relatively small, which affects the power output; if the power required for the water to flow upward is insufficient, it will lead to insufficient water flow.

[0003] Furthermore, the sealing of the various through-holes in the fluid channels for water inlet and outlet needs to be strengthened, and the sealing or opening force needs to be maintained continuously. A recessed air distribution chamber is located on the valve plate around the water inlet and outlet, with a partition separating the air distribution chamber from the outlet, creating separate cavities for water inlet and outlet. However, this micro water pump can experience siphoning after discharging liquid. Utility Model Content

[0031] The distance between the water inlet 22 and the water outlet 24 of the above valve seat assembly 20 is relatively large, which can leave enough space for designing pressure changes, driving force and other structures; the pressure regulating part between the valve seat upper cover 23 and the lower cover is set as a leather bowl body 11, and the leather bowl body 11 has a large space and can generate a large negative pressure, so that the amount of water absorbed each time it is compressed is also large, and the overall power of the water pump is sufficient and the efficiency is high.

[0032] In this preferred embodiment, the drive assembly includes a drive motor, an eccentric wheel 32, and a swing frame 33, which are sequentially connected from bottom to top. The eccentric wheel 32 of the drive assembly cooperates with the swing frame 33 to drive at least two leather cups 11, thereby achieving alternating and equal water absorption by the two leather cups 11, thereby achieving a good water flow rate.

[0033] In this preferred embodiment, at least two leather bowl bodies 11 are provided, and several leather bowl bodies 11 are symmetrically arranged along a vertical line; a water bag cavity 12 with an upward opening is provided at the upper part of the leather bowl body 11, and the longitudinal section of the water bag cavity 12 is U-shaped; a connecting head 13 is provided at the lower part of the leather bowl body 11, and the longitudinal section of the connecting head 13 is I-shaped; the number of swing arms of the swing frame 33 corresponds to the number of leather bowl bodies 11, and one side of the top of the swing frame 33 is clamped in the I-shaped groove of the connecting head 13.

The water inlet 22, the first fluid cavity 25, the water bag cavity 12, the second fluid cavity 26, and the water outlet 24 are connected in sequence to form a fluid channel.

[0036] In this preferred embodiment, the valve assembly 40 includes a first one-way valve 41 and a second one-way valve 42, which are sequentially arranged in the fluid passage. The first one-way valve 41 is arranged at the bottom of the valve body lower cover and at the top of the leather cup body 11. The first one-way valve 41 is used to seal or open the passage between the first fluid chamber 25 and the water bladder chamber 12; the second one-way valve 42 is arranged at the top of the valve body lower cover and inside the second fluid chamber 26. The second one-way valve 42 is used to seal or open the passage between the water bladder chamber 12 and the second fluid chamber 26. Specifically, the first one-way valve 41 and the second one-way valve 42 are both umbrella-shaped one-way valves, which can fully seal the fluid passage under normal conditions; the above valve assembly 40 has a good sealing or conduction effect.

Under normal conditions, the water stop valve core 44, under the elastic action of the water stop spring 45, continuously seals the third through-hole of the water stop valve body 43, preventing backflow and siphoning.

[0039] The basic working principle of this utility model is:

[0040] First, the drive motor of the drive assembly sequentially drives the eccentric wheel 32 to rotate and the swing frame 33 to swing, thereby driving the three leather cup bodies 11 to move vertically upward in sequence. The leather cup body 11 seals the bottom of the valve seat lower cover 21, generating negative pressure in the water bladder chamber 12 of the leather cup body 11, and generating suction toward the water inlet 22. Then, fluid (water) enters the first fluid chamber 25 of the fluid channel from the water inlet 22. The water in the first fluid chamber 25 presses downward on the first one-way valve 41 through the valve seat lower cover 21, and the first one-way valve 41 opens the first through-hole between the first fluid chamber 25 and the water bladder chamber 12 of the leather cup body 11. Then, the water in the water bladder chamber 12 of the leather cup body 11 moves upward from the leather cup body 11 to open the second one-way valve 42, that is, to open the second through-hole between the water bladder chamber 12 of the leather cup body 11 and the second fluid chamber 26. Finally, the water enters the bottom of the second fluid chamber 26 and passes through the third through hole of the water stop valve body 43; the water pressure opens the water stop valve core 44 from bottom to top, the water stop spring 45 is contracted, and the water enters the top of the second fluid chamber 26 and is discharged from the water outlet 24.
