Adjustable caliber high temperature and high pressure steam car washing spray gun and its caliber automatic adjustment method

Abstract

The invention discloses a high-temperature and high-pressure steam car washing spray gun with adjustable caliber and an automatic adjustment method for the caliber. The spray gun includes a spray gun body, a spray head body, an adjustment mechanism, a driving mechanism and a controller. The spray gun body has a spray channel inside, and the spray head body is installed on the nozzle end of the spray gun body and communicates with the spray channel. The spray head body includes an elastic nozzle structure and a lubricating block. The lubricating block is installed on the nozzle end of the spray gun body and is provided with a sizing through hole communicating with the spray channel. The elastic spout structure is attached to and sleeved on the lubricating block, and a variable diameter through hole communicated with the fixed diameter through hole and coaxially arranged is opened. The adjustment mechanism includes a worm and a turbine. The worm is movably mounted on the spray gun body and coaxially arranged with the reducing through hole. The worm is fixedly connected with one end of the elastic spout structure away from the through hole of the variable diameter. The turbine is mounted on the gun body and meshes with the worm. The invention can adjust the caliber, has high adjustment precision, reduces the labor intensity of car washers and reduces the time for replacing the nozzles.

Description

technical field

[0001] The invention relates to a spray gun in the technical field of vehicle cleaning, in particular to a high-temperature and high-pressure steam car washing spray gun with adjustable caliber, and also relates to a method for automatically adjusting the caliber of the spray gun. Background technique

[0002] Steam car wash spray gun is a key component of steam car wash equipment. High-pressure steam can not only disinfect, but also decontaminate. It has a unique thermal decomposition function, which can quickly dissolve the sticky nature of sediment and stains, and let them detach from the attached car surface to achieve the purpose of cleaning; high pressure is used to remove the attached For stains on the surface, high temperature is used to increase the activity of the stain "molecules" to facilitate high-pressure flushing. Avoid scratches on the car body caused by vigorously wiping the car body and damage to the protective layer on the surface of the a...
