SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to above-mentioned prior art current situation and provide one kind can be with the water loss's of preventing water pressure water pump water spray structure from each hole for water distribution in the pump case inner chamber comparatively on average.
The water outlet structure of the water pump has reasonable structure and ensures that the sprayed water is not easy to flow backwards from the water spraying holes.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: a water pump water spraying structure preventing water pressure loss comprises a pump shell with a water inlet and a water pressing component arranged in an inner cavity of the pump shell and used for driving water flow, wherein a pump shaft used for being connected with a mop head penetrates through the pump shell, the water pressing component can be driven to rotate by the rotation of the pump shaft, a water outlet channel communicated with the inner cavity of the pump shell is arranged on the pump shell, a water spraying hole used for spraying water to a wiping object is formed in the water outlet channel along the length direction of the water outlet channel, and an inlet end communicated with the inner cavity of the pump shell is further arranged on the water outlet channel; the method is characterized in that: the inlet end is positioned in the middle of the water outlet channel, so that the positions of two sides of the inlet end are both provided with the water spray holes.
In a further improvement, the top surface of the pump shell is provided with a water retaining platform protruding upwards, and the water outlet channel is arranged in the water retaining platform. The water blocking platform can lift the position of the water spraying hole, so that water is effectively prevented from flowing backwards from the water spraying hole to enter the inner cavity of the pump shell; meanwhile, in the process of swinging the mop head, the thrown water can be blocked by the water retaining table, so that the cost is prevented from being reduced to the wiping materials of the mop head.
Preferably, the water blocking table is arranged in a radial direction.
For convenient assembly, the pump shell is formed by involutory connection of an upper shell and a lower shell, and the water retaining platform is arranged on the top surface of the upper shell.
Alternatively, the plurality of water spraying holes are arranged at intervals, or the whole water spraying hole is in a strip shape.
Compared with the prior art, the utility model has the advantages of: the inlet end is positioned in the middle of the water outlet channel, so that the positions on two sides of the inlet end are respectively provided with the water spray holes, the distance between the inlet end and the water spray hole at the farthest end is shortened, the water pressure loss is reduced, and water flow is uniformly distributed to the water spray holes along the length direction.
