High-pressure water gun flushing gun head and high-pressure water gun comprising same

Abstract

The invention discloses a high-pressure water gun flushing gun head. The high-pressure water gun flushing gun head comprises a handle, a water inlet pipe and a gun head, and is characterized in that the gun head comprises a double-layer pipeline, a straight spray head and a rotary spray head, one end of the double-layer pipeline is connected with the water inlet pipe, the other end of the double-layer pipeline is connected with the rotary spray head and the straight spray head, the straight spray head is arranged at the center of the rotary spray head, the double-layer pipeline is divided intoan inner layer and an outer layer, an outlet of the inner layer is connected with the straight spray head, an outlet of the outer layer is connected with the rotary spray head, the rotary spray headis connected with the outlet of the outer layer of the double-layer pipeline through a sealing bearing, and self-rotates through the sealing bearing, a nozzle on the rotary spray head is arranged at the periphery or the top end of the rotary spray head, the nozzle on the rotary spray head is formed by a hole and / or groove, the rotary spray head is further provided with bristles, and the bristles are arranged at the nozzle and / or the top end of the rotary spray head. According to the high-pressure water gun flushing gun head, the structure is simple, the design is reasonable, and multi-functioncleaning modes such as straight spraying, rotating and brushing can be achieved by changing water spraying modes.

Description

technical field [0001] The present invention relates to the field of PCB board manufacturing, and more specifically relates to a high-pressure water gun flushing gun head for maintaining the horizontal line of PCB boards and a high-pressure water gun composed of the same. Background technique [0002] Printed circuit board, also known as printed circuit board, printed circuit board, referred to as printed board, referred to as PCB in English, uses an insulating board as the base material, cut to a certain size, with at least one conductive pattern attached to it, and holes. It is used to replace the chassis used to install electronic components and realize the interconnection between electronic components. In the production process of circuit boards, various horizontal lines are needed. When maintaining the horizontal lines, high-pressure water guns are generally used for flushing. Due to the single function, only With the function of washing, the debris adhering to the tank...

[0002] Printed circuit board, also known as printed circuit board, printed circuit board, referred to as printed board, referred to as PCB in English, uses an insulating board as the base material, cut to a certain size, with at least one conductive pattern attached to it, and holes. It is used to replace the chassis used to install electronic components and realize the interconnection between electronic components. In the production process of circuit boards, various horizontal lines are needed. When maintaining the horizontal lines, high-pressure water guns are generally used for flushing. Due to the single function, only With the washing function, the sundries adhering to the tank wall may not be rinsed cleanly, and the high-pressure water gun has too little effect on stubborn stains, so after washing with a direct-injection high-pressure water gun, manual scrubbing is required, which is time-consuming and laborious
