Abstract

The utility model provides a water-saving car washing spray gun utilizing high-pressure air-water, comprising a gun body (1), an air supply tube (2), a mixing tube (3), a gun nozzle (4), a water supply tube (6) and a flow control valve (5), wherein the flow control valve (5) is connected to the air supply tube (2), and the air supply tube (2) is connected with the gun body (1). High-pressure air in the air supply tube (2) and water input by the water supply tube (6) are uniformly mixed in the mixing tube (3) and then sprayed out via the gun nozzle (4). The flow control valve (5) can be adjusted as needed during a use process and can be closed in a special situation. The water-saving car washing spray gun utilizing high-pressure air-water provided by the utility model is simple in structure and capable of saving water source during a car washing process, which can be widely applied to small and medium car washing operators.

Description

Water-saving high-pressure air water spray gun for washing car

Technical Field

The invention relates to a spray gun technology, in particular to a water-saving high-pressure air water vehicle washing spray gun.

Background

Along with the improvement of the living standard and the acceleration of the life rhythm of people, the group of car buying is continuously increased, and the car washing operators are more and more. At present, car washing operators mainly adopt small and medium scales, and the car washing mode is that water is directly pressurized to be sprayed onto the surface of a car body, so that the car washing operators can passively keep enough water for achieving and keeping corresponding flushing force, the water consumption for car washing is increased, water waste is caused, water resources are not saved, and the cost of the operators is increased.

Various car washing spray guns exist for solving the problems, but the structures of the car washing spray guns are complicated; one of the high-pressure car washing guns is a water-saving high-pressure air water car washing gun in the Chinese invention patent with the application number of 200520014868. The invention provides a water-saving high-pressure air-water vehicle washing gun, which is provided with a gun body with a cavity and a water inlet pipe, wherein the water inlet pipe is arranged at the tail part of the gun body and is connected with an external water source.

Therefore, in the prior art, the water-saving high-pressure air water spray gun has a complex structure and is inconvenient to use, and the flow of high-pressure air cannot be controlled.

Disclosure of Invention

In view of the above, the main object of the present invention is to provide a water-saving high-pressure air-water vehicle-washing spray gun with simple structure, convenient use and controllable air flow.

In order to achieve the purpose, the technical scheme provided by the invention is as follows:

the water-saving high-pressure air-water vehicle washing spray gun comprises a gun body (1), a water supply pipe (6) for supplying water, an air supply pipe (2) for supplying air, a mixing pipe (3) for mixing water and air, two flow control valves (5) for controlling air flow, and a gun nozzle (4) for ejecting an air-water mixture; wherein,

one end of the mixing pipe (3) is connected with the gun body (1), the other end of the mixing pipe is connected with the gun nozzle (4), the air supply pipes (2) are horizontally and symmetrically connected to two sides of the gun body, and the two air supply pipes (2) are respectively provided with a flow control valve (5).

In conclusion, the water-saving high-pressure air-water vehicle washing spray gun comprises a gun body (1), an air supply pipe (2), a mixing pipe (3), a gun nozzle (4), a water supply pipe (6) and a flow control valve (5), and has no complex structure; when the water-saving high-pressure air-water vehicle washing spray gun runs, high-pressure air and water are mixed and then are ejected from the gun nozzle (4), the water consumption is less than that when water is used for directly ejecting water to a vehicle body during vehicle washing, and the flow of the air can be controlled.

FIG. 2 is a schematic sectional view of a gas supply pipe and a flow control valve.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

FIG. 1 is a schematic view of the structure of the water-saving high-pressure air-water vehicle-washing spray gun of the present invention. As shown in fig. 1, the water-saving high-pressure air-water spray gun comprises a gun body (1), a water supply pipe (6) for supplying water, a gas supply pipe (2) for supplying gas, a mixing pipe (3) for mixing water and air, two flow control valves (5) for controlling the flow rate of the air, and a gun nozzle (4) for ejecting an air-water mixture; wherein,

In practice, the flow control valve may be adjusted to adjust different air flow rates.

In a word, when a vehicle needs to be washed, water enters the gun body (1) from the water supply pipe (6) and flows through the mixing pipe (3) to be ejected from the gun nozzle; and opening the flow control valve (5), and injecting high-pressure air into the gun body (1) from the air supply pipe (2) and uniformly mixing the high-pressure air and water in the mixing pipe (3) and then injecting the mixture from the gun nozzle (4).

FIG. 2 is a schematic view of the structure of the gas supply pipe and the flow control valve. As shown in fig. 2, the upper portion of each air supply pipe (2) is provided with a flow control valve (5) for controlling the flow rate of air.

In practical application, the introduction of high-pressure air can generate unbalanced force on the original water flow, so that the air supply pipe (2) is symmetrically arranged and is obliquely inclined backwards to offset the generated unbalanced force to the maximum extent.

In summary, the above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
