Description

Water spraying mechanism

Technical Field

The invention relates to the technical field of floor cleaning, in particular to a water spraying mechanism.

Background

The floor washing machine is a cleaning machine which is suitable for cleaning hard ground and simultaneously sucking and drying sewage and taking the sewage away from the site, and has the advantages of environmental protection, energy conservation, high efficiency and the like. The working principle of the existing conventional floor washing machine is as follows: the water pump sprays clean water to the clean part outside the roller brush main body through a plurality of water outlets. The wiper blade wipes off stains on the cleaning part outside the roller brush main body. The water pressure loss of the water supply pipeline is large. After the water of each water spraying hole overflows, the water is converged into water flow to the local surface of the rolling brush at a slow speed under the action of surface tension. To improve the self-cleaning ability during cleaning, more water nozzles are needed, but the water pressure loss of the water supply pipeline is larger. Leading to some individual water jet, under the interference of surface tension of water, can not spill over the clear water to the external world, therefore the water spray mechanism of scrubber has following defect:

1. because of the resistance of each water supply pipeline (the surface tension influence of water molecules), the water quantity of each water outlet is inconsistent, and the water spraying quantity of a local water outlet is larger than the water scraping quantity (the recovered water quantity) of the water scraping plate. More water stain remains on the floor. The floor is not thoroughly cleaned.

2. The water spraying is uneven, the surface of the roller brush main body is not sprayed with clear water at certain positions, and stains on the surface of the roller brush main body are not easy to scrape. Therefore, the dirt at some positions is accumulated more and more in the whole moving process of the rolling brush. The outer surface of which does not maintain a continuous self-cleaning capability. The efficiency of sanitary cleaning is low.

Example (b):

referring to fig. 1-3, the present invention provides a technical solution: a water spraying mechanism comprises water pumps 2 and cleaning components 6, wherein the number of the water pumps 2 is not less than two, the water outlet ends of the water pumps 2 are connected with the water inlet end of a pressure maintaining chamber 4 through a water outlet pipe 3, a plurality of water pumps (at least 2) inject clean water into the pressure maintaining chamber 4 through the pressure of the water pumps 2, the number of the pressure maintaining chamber 4 is consistent with that of the water pumps 2, a plurality of water outlets 5 used for flushing the cleaning components 6 are formed in the pressure maintaining chamber 4, water in the pressure maintaining chamber 4 is sprayed out from the water outlets 5, the total area of the water outlets 5 is smaller than the area of the water inlet end, so that the water pressure in the pressure maintaining chamber 4 can be maintained in a certain range, each water outlet 5 can spray columnar clean water to the outside under the internal high water pressure, the clean water sprayed to the cleaning components 6 is more uniform, and a water scraping plate 7 used for scraping stains on the cleaning components 6 is arranged below the pressure maintaining chamber 4, the wiper blade 7 is used to wipe off dirt on the cleaning member 6.

The water inlet end of the water pump 2 is connected with the clean water tank 8 through the water inlet pipe 1, the connection position of the water inlet end of the pressure-maintaining chamber 4 and the water outlet pipe 3 is provided with a sealing ring, the sealing performance is guaranteed, the water pressure in the pressure-maintaining chamber 4 is greater than the surface tension of water in the water outlet 5, so that each water outlet 5 can spray water to the outside, the water outlet 5 can spray intensive columnar clean water to the outside to act on the cleaning component 6 to wash the cleaning component 6, the water pump 2 is a high-pressure water pump, the number of the pressure-maintaining chambers 4 is not less than two, and each pressure-maintaining chamber 4 has independent pressure-maintaining pressure, and the water pressure in each pressure-maintaining chamber 4 can be maintained in a certain range.

The working principle is as follows: the clear water in the clear water tank 8 is injected into the pressure maintaining chamber 4 by a plurality of water pumps (at least 2) through the pressure of the water pumps 2, and the total area of a plurality of water outlets 5 on the pressure maintaining chamber 4 is smaller than the area of the water inlet end of the pressure maintaining chamber 4: therefore, the water pressure in the pressure holding chamber 4 can be maintained in a certain range, each water outlet 5 can spray dense columnar clear water to the outside under the internal high water pressure, the clear water sprayed to the cleaning part 6 is more uniform, when the number of the water outlets 5 in the pressure holding chamber 4 is too large, the water pressure in the pressure holding chamber 4 can be reduced, and the water pressure is insufficient to support the columnar clear water to be sprayed to the outside, so that the number of the controllable water outlets 5 determines the upper limit after the specification and the pressure of the water pump 2 are determined. The cleaning component 6 of the actual product is longer, and in order to ensure that the surface of the cleaning component 6 can receive dense columnar clear water, the principle of adding the water pump 2 and driving other pressure-maintaining chambers 4 can be adopted to copy the water spraying coverage in the previous pressure-maintaining chamber 4.
