Description

An integrated structural point spray gun Technical Field

[0001] The present invention relates to the technical field of spray guns, and more particularly to an integrated structural point spray gun. Background Art

[0002] Most existing spray guns cannot adjust the spray angle of the liquid, which is basically equivalent to direct spraying, which is not conducive to use. Direct spraying easily forms paint accumulation, resulting in uneven thickness. For example, when painting a car, it is generally necessary to spray at a certain angle, but the angle can vary greatly when holding the spray gun by hand.

[0003] Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an integrated structure point spray gun that can spray paint at a certain angle when held directly by hand, and the variation range of the spray angle is small.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A one-piece structure dot spray gun, comprising a spray gun and a paint dot pen, a gun head is provided on one side of the top of the spray gun, an air pressure chamber is provided inside the spray gun, an electric air pump is provided in the air pressure chamber, an air outlet is provided on the top of the air pressure chamber, the air outlet is provided for guiding the airflow, a pressurized pipe is provided on the top of the air outlet, a pressurized port is provided at one end of the pressurized pipe away from the air outlet, a spray head is provided at one end of the pressurized port, a spherical hinge support is provided at the lower end of the gun head of the spray gun, a rolling ball is provided at the top of the paint dot pen corresponding to the spherical hinge support, and the rolling ball is movably arranged in the spherical hinge support.

[0007] The top of the paint-pointing pen is provided with an atomizing nozzle, the top of the atomizing nozzle is overlapped with the top of the spray gun nozzle, and the bottom of the paint-pointing pen is a material storage tank.

[0008] As a further improvement, a circuit board is provided inside the spray gun, the electric air pump is electrically connected to the circuit board, and a switch is provided on the outer surface of the spray gun, and the switch is electrically connected to the circuit board.

[0009] A further improvement includes a power supply, which is electrically connected to the circuit board.

[0010] Further improvement, the power source is a battery;

[0011] As a further improvement, a nozzle is connected between the atomizing nozzle and the storage tank.

[0012] As a further improvement, the atomizing nozzle is a spray needle.

[0013] According to a further improvement, the spray gun is formed by injection molding.

[0014] In summary, the present invention has the following beneficial effects:

[0015] 1. The spherical hinge support and the rolling ball are connected in coordination so that the present invention can spray paint at a certain angle when held by hand, and the variation range of the spray angle is small, which is more suitable for use in scenes where spraying at a certain angle is required.

[0016] 2. By setting up switches, pressurized pipes, circuit boards and other mechanisms, the device can effectively open, close and output the flow rate of the airflow through the electric air pump controlled by the circuit board when in use. The pressurized pipe, pressurized port and nozzle can increase the air pressure. The cooperation of the rolling ball and the spherical hinge support allows the paint-pointing pen to rotate on the spherical hinge support. The spray needle has a simple structure, which can reduce the volume of liquid when flowing out of the paint-pointing pen and is easier to atomize. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The present invention provides a technical solution, an integrated structure dot spray gun 1, comprising a spray gun 1 and a paint dot pen 2, a gun head 3 is provided on one side of the top of the spray gun 1, an air pressure chamber 4 is provided inside the spray gun 1, an electric air pump (not shown in the drawings) is provided in the air pressure chamber 4, an air outlet 5 is provided on the top of the air pressure chamber 4, the air outlet 5 is provided for guiding the airflow, a pressurized pipe 6 is provided on the top of the air outlet 5, a pressurized port is provided at one end of the pressurized pipe 6 away from the air outlet 5, a spray head 7 is provided at one end of the pressurized port, a spherical hinge support 8 is provided at the lower end of the gun head 3 of the spray gun 1, a rolling ball is provided at the top of the paint dot pen 2 corresponding to the spherical hinge support 8, and the rolling ball is movably arranged in the spherical hinge support 8.

[0025] The top of the paint-pointing pen 2 is provided with an atomizing nozzle. In this embodiment, the atomizing nozzle adopts a spray needle 12, the top of the spray needle 12 overlaps the top of the dot nozzle 7, and the bottom of the paint-pointing pen 2 is a material storage tank. A nozzle 11 is connected between the spray needle 12 and the material storage tank. A circuit board (not shown in the drawings) is provided inside the spray gun 1.

[0028] Working principle: Start the switch 10, the circuit board controls the electric air pump to start, the electric air pump outputs gas, through the pressurized pipe 6, the pressurized port, the nozzle 7 increases the air pressure, and the nozzle 7 sprays out a high-speed airflow, thereby forming a low-pressure area at the top of the spray needle 12. At this time, the pressure on the top of the spray needle 12 is lower than the internal pressure of the paint point pen 2. The liquid paint in the material tank of the paint point pen 2 will flow out through the spray needle 12 due to the air pressure difference and be atomized when passing through the high-pressure gas.

[0029] By controlling the flow rate of the airflow output by the electric air pump through the circuit board, the flow rate of the airflow sprayed from the nozzle 7 can be controlled, thereby changing the amount of paint liquid output.
