Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the utility model or equivalent substitutions of parts of technical features without departing from the spirit of the utility model are intended to be covered by the scope of the claims of the utility model.

Example one

As shown in fig. 1 to 4, the present embodiment provides a washing water pump, which includes a pump housing 1, a regulator 2, a driving assembly 3, a water path system and an air path system, wherein the pump housing 1 has at least one chamber (not shown). The regulating member 2 is rotatably provided in the chamber, and the regulating member 2 partitions the chamber into the gas chamber 11 and the liquid chamber 12. The driving assembly 3 is arranged outside the pump shell 1, and the output end 31 of the driving assembly 3 is movably connected with the adjusting piece 2 and is used for driving the adjusting piece 2 to rotate so as to adjust the volumes of the air chamber 11 and the liquid chamber 12, when the output end 31 of the driving assembly 3 rotates anticlockwise and the adjusting piece 2 can be driven to rotate towards the air chamber 11, the volume of the air chamber 11 is gradually reduced, and the volume of the liquid chamber 12 is gradually increased; conversely, when the output end 31 of the driving assembly 3 rotates clockwise, the volume of the air chamber 11 gradually increases and the volume of the liquid chamber 12 gradually decreases as the adjusting member 2 is driven to rotate toward the liquid chamber 12, so that it can be seen that the volume of the air chamber 11 and the liquid chamber 12 can be adjusted by pushing the adjusting member 2 to rotate between the air chamber 11 and the liquid chamber 12. The waterway system comprises a water inlet assembly 41 and a water outlet assembly 42, wherein the water inlet assembly 41 and the water outlet assembly 42 are respectively and selectively communicated with the liquid chamber 12. The air path system comprises an air inlet assembly 51 and an air outlet assembly 52, wherein the air inlet assembly 51 and the air outlet assembly 52 are respectively and selectively communicated with the air chamber 11.

When the adjusting piece 2 is driven to rotate towards the air chamber 11, the volume of the air chamber 11 is reduced, at the moment, the air inlet assembly 51 is switched to be not communicated with the air chamber 11, an external air source cannot flow into the air chamber 11 through the air inlet assembly 51, the air outlet assembly 52 is switched to be communicated with the air chamber 11, and air in the air chamber 11 flows into a nozzle assembly of the range hood through the air outlet assembly 52; meanwhile, because the volume of the air chamber 11 is reduced, the volume of the liquid chamber 12 is increased on the contrary, the water inlet assembly 41 is switched to be communicated with the liquid chamber 12, an external water source flows into the liquid chamber 12 through the water inlet assembly 41, the water outlet assembly 42 is switched to be not communicated with the liquid chamber 12, and at the moment, water in the liquid chamber 12 cannot flow into the nozzle assembly of the range hood through the water outlet assembly 42. On the contrary, when the adjusting part 2 is driven to rotate towards the liquid chamber 12, the volume of the air chamber 11 is increased, at this time, the air inlet assembly 51 is switched to be communicated with the air chamber 11, the external air source flows into the air chamber 11 through the air inlet assembly 51, the air outlet assembly 52 is switched to be not communicated with the air chamber 11, and the air in the air chamber 11 cannot flow into the nozzle assembly of the range hood through the air outlet assembly 52; meanwhile, the volume of the liquid chamber 12 is reduced, the water inlet assembly 41 is switched to be not communicated with the liquid chamber 12, an external water source cannot flow into the liquid chamber 12 through the water inlet assembly 41, the water outlet assembly 42 is switched to be communicated with the liquid chamber 12, and at the moment, water in the liquid chamber 12 flows into the nozzle assembly of the range hood through the water outlet assembly 42. It can be seen that by feeding water into the liquid chamber 12 and ejecting gas from the air chamber 11 when the volume of the liquid chamber 12 is increased and feeding water into the liquid chamber 12 and feeding water into the air chamber 11 when the volume of the liquid chamber 12 is decreased, alternating flow of gas and water into or out of the pump housing 1 is achieved, a segment of water column can be ejected by means of a high pressure release process of compressed air, increasing the speed of ejecting the water column and enhancing the cleaning effect.

It can be seen that, in the cleaning water pump of the present embodiment, the adjusting member 2 is rotatably disposed between the air chamber 11 and the liquid chamber 12, so as to adjust the volume of the air chamber 11 and the liquid chamber 12; when the volume of the liquid chamber 12 is increased, water enters the liquid chamber 12 and the air chamber 11 sprays gas, and when the volume of the liquid chamber 12 is reduced, the liquid chamber 12 sprays water and the air chamber 11 feeds air, so that the alternative inflow or outflow of the gas and the water flow to the pump shell 1 is realized, a high-pressure release process of compressed air can be relied on, a section of water column is sprayed out, the speed of spraying the water column is increased, the cleaning water pressure is obviously improved, and the cleaning effect is favorably enhanced.
