Spraying control device used for washing automobile

Abstract

A spraying control device used for washing an automobile comprises a spray rod. Nozzles distributed at intervals up and down are arranged on the spray rod. The spray rod is a hollow rod body. An innercasing pipe capable of moving up and down along the inner wall of the spray rod is arranged in an inner cavity of the spray rod. The outer wall of the inner casing pipe and the inner wall of the spray rod are attached and sealed. Circulation holes distributed up and down are formed in the inner casing pipe. The sizes and the shapes of the nozzles are the same. The number of the nozzles is equal to that of the circulation holes. The circulation holes are vertical kidney-shaped holes. The vertical distances between the vertical kidney-shaped holes distributed from top to bottom are gradually lengthened. The interval distance between every two adjacent nozzles needs to be larger than the length of a vertical opening of the bottommost vertical kidney-shaped hole. An inner cavity of the innercasing pipe communicates with a water source. A drive mechanism driving the inner casing pipe to move up and down along the inner wall of the spray rod is arranged on the spray rod. A drive motor in the drive mechanism is connected with a program control circuit. The spraying control device has the beneficial effects of being wide in application range, high in practicability, small in weight and capable of reducing the water use amount for washing the automobile and saving resources.

Description

technical field [0001] The invention relates to the technical field of cleaning equipment manufacturing, in particular to a spray control device for cleaning cars. Background technique [0002] A kind of patent No. disclosed by the present inventor is the Chinese invention patent of CN201410242085.4 title " car cleaning device ", and this car cleaning device comprises spraying device, and described spraying device comprises the top spray bar that is arranged horizontally and The vertical spray bars arranged on the left and right, the vertical spray bars and / or the top spray bars are respectively provided with switching mechanisms that enable the nozzles to spray air or water, and the switching mechanisms are linked with the output shaft of the switching motor. The switching mechanism includes a cylindrical tube that can rotate relative to the inner wall of the corresponding spray rod and is arranged together in a mutually sealed manner. There are vent holes and nozzles that ...

Problems solved by technology

For example, it is difficult to apply to oval pipes, square pipes and other galvanized pipes with non-circular cross-sections, or thick welds inside and poor roundness; The liquid holes and the number of controlled nozzles are too small; moreover, for the commonly used spray rods that are bent to adapt to the contour of the body or have joints in the middle, it is difficult for the cylindrical tube to cross the bend or joint to control the opening and closing of the nozzles ,and many more
