An anti-drip high and low pressure combined nozzle and high pressure cleaning equipment

Abstract

The invention discloses an anti-dripping high-low-pressure combined nozzle and high-pressure cleaning equipment. The anti-dripping high-low-pressure combined nozzle comprises a high-pressure nozzle body, a sliding valve, a head shell, a low-pressure nozzle body and a spring. The high-pressure nozzle body is provided with a center spray channel. The sliding valve is provided with a water hole. Thehead shell is provided with a cavity penetrating the front end and the rear end of the head shell and being used for containing the high-pressure nozzle body and the sliding valve. The low-pressure nozzle body is provided with a main water outlet and at least one auxiliary water outlet formed in the peripheral side of the main water outlet. The sliding valve is slidably arranged on the rear portion of the high-pressure nozzle body. Sliding sealing is formed between the outer wall of the sliding valve and the cavity wall of the cavity. A bypass path is formed between the outer wall of the high-pressure nozzle body and the cavity wall of the cavity. The low-pressure nozzle body is slidably arranged in the cavity of the head shell and in sliding sealing fit with the head shell. The low-pressure nozzle body is located in the front of the high-pressure nozzle body. The spring is located in the cavity of the head shell and abuts against the low-pressure nozzle body and the head shell. The low-pressure nozzle body can be in contact with the high-pressure nozzle body to form sealing. The auxiliary water outlets communicate with the bypass path. The anti-dripping high-low-pressure combinednozzle has the beneficial effect that the dripping phenomenon of the water outlets can be improved effectively and eliminated.

Description

technical field [0001] The invention belongs to the technical field of cleaning equipment, and in particular relates to an anti-drip high and low pressure combined nozzle and high-pressure cleaning equipment. Background technique [0002] High-pressure cleaning equipment is a kind of equipment that uses water or a mixed solution added with cleaning agent as the cleaning medium, and uses high-pressure water flow to clean the surface of the object. It is mainly composed of a spray gun unit and a motor pump unit. The spray gun unit is responsible for forming different shapes according to actual needs. water flow, while the motor-pump unit delivers the water from the municipal water mains to the spray gun unit. [0003] Nozzles / sprinklers are the executive elements in high-pressure water cleaning equipment. The principle is to use the change of the inner hole area of ​​the nozzles / sprinklers to gather high-pressure water, convert it into kinetic energy and then spray it out in t...

AI Technical Summary

Problems solved by technology

However, how to realize the combination of high-pressure nozzles and low-pressure nozzles, and how to achieve simple structure, reliability, easy manufacture, convenient assembly, and convenient adjustment of high and low pressure, stable performance, safety, and good cleaning effect have always been troubled by practitioners. question

[0004] The invention patent with the application number "201410779402.6" and the title "A High and Low Pressure Nozzle Assembly for High Pressure Cleaning Equipment" discloses a nozzle assembly capable of high and low pressure conversion, through the cooperation between the sliding valve and the high pressure nozzle Change the flow of water entering the bypass path to achieve high and low pressure conversion, but when the bypass path is just activated, due to the small water flow at this time, resulting in insufficient outlet pressure, part of the water flow will be sprayed out in the form of a water column while the other part will be Drip directly from the water outlet, which also affects the normal use of the device
