As shown in Figure 1, a spray gun 10 consists of a grip 11 connected to a tube body 12 to form a hollow gun body shape. Wherein, the two ends of the tube body 12 are a liquid inlet 14 and an outlet 15, and the tube body 12 forms a section of external thread 17 around the outlet 15. One end of a pipe joint 18 is connected to the pipe body 12, and the other end is inserted into a pipe to guide liquid (such as water) into the spray gun 10, so the free end of the pipe joint 18 serves as the liquid inlet 14 for use. In this embodiment, the pipe joint 18 is equipped with a switch 19, and the switch 19 is a one-way valve that determines the flow rate of the liquid to the spray gun 10 through the liquid inlet 14. One end of the holding portion 11 is connected to the tube body 12, and the other end is a gas inlet 13. The gas inlet 13 and the liquid inlet 14 communicate with the outlet 15, so that the spray gun 10 has a three-way internal structure. The holding portion 11 is equipped with a button 16 which is adjacent to the tube body 12 and controls an air compressor (not shown in the figure) to generate a flow of high-pressure gas that flows to the gas inlet 13 and enters the spray gun 10 via other pipelines.

In Figure 2, a three-dimensional view of the first spray head 20 is drawn, which has a spraying end 21 and a connecting end 22 that communicate with each other. In this embodiment, the coupling end 22 is a nut, which is integral with the spray head 20 and is fixed. The coupling end 22 is provided with a section of internal thread 23 that can lock the external thread 17 of the tube body 12 so that the outlet 15 of the spray gun 10 communicates with the spray end 21 of the spray head 20.

In some embodiments, the coupling end 22 is still a nut, and the nut is rotatable relative to the spray head 20. Assuming that the spray head 20 does not move, the coupling end 22 can still be rotated, and the external thread 17 of the spray gun 10 is locked with the internal thread 23 to complete the assembly of the spray head 20 and the spray gun 10.

FIG. 3 is a perspective view of the spray gun 10 and the spray head 20. Assume that the switch 19 is in a closed position. A user grips the grip 11 and continuously applies force to the button 16 so that high-pressure gas continuously enters the spray gun 10 through the gas inlet 13 and is sprayed out from the spray end 21 of the spray head 20 under high pressure. At this moment, the spray gun 10 has a high-pressure air jet function, which is suitable for cleaning the surface of objects.

If so, the switch 19 is in an open position. The liquid inlet 14 guides liquid (for example, water) through the tube body 12, and the mixed gas becomes a high-pressure fluid, which is then sprayed out from the spray end 21 of the spray head 20 in the form of a water column. At this moment, the spray gun 10 has a hydraulic spray function, which is suitable for washing the surface of an article.

As shown in FIG. 4, the spray head 30 belongs to the second mode, and its two ends are also connected to the spray end 31 and the connection end 32. Compared with the first mode, the locking method of internal and external threads is also adopted, the coupling end 32 is combined with the outlet of the spray gun 10, and the spray head 30 is used to enhance the spraying effect.

The difference is that between the spray end 31 and the coupling end 32 is a branch pipe 33 which connects the spray head 30 and a cover 34 together. A container 35 for adding solution is detachable by combining or locking the bottom end of the lid 34.

Assume that the switch 19 is in the open position. The button 16 is continuously pressed by the user, and the liquid and gas are mixed in the spray gun 10 into a high-pressure fluid. Because the branch pipe 33 connects the spray head 30 and the cover 34, the high-pressure fluid passes through the spray head 20 to generate suction, thereby sucking the solution in the container 35. The solution may be a detergent, a brightener or a waxy substance, and the mixed high-pressure fluid is sprayed out from the spraying end 21, which can improve the surface brightness of objects such as vehicles and prevent metal objects from rusting. Therefore, the spray gun 10 has the function of spraying high-pressure fluid, which is suitable for the maintenance and maintenance of the film formed on the surface of the article.

As shown in FIG. 5, the spray head 40 belongs to the third mode, and its two ends are also connected to the spray end 41 and the coupling end 42. Compared with the second mode, the thread locking method is also used to connect the coupling end 42 to the outlet of the spray gun 10, and the spray head 40 is used to enhance the spray effect. The branch pipe 43 connects the spray head 40 and the lid 44 together, so that the container 45 is detachably combined under the lid 44.

The difference is that one end of a long and narrow tube 46 is connected to the spray head 40, and the other end is used as the spray end 41. Therefore, the long and narrow tube 46 extends the distance from the spray end 41 to the coupling end 42, so that the branch pipe 43, the lid 44 and the container 45 are close to the coupling end 42 of the spray head 40.

As shown in FIG. 6, the spray head 50 is in the fourth mode, and the two communicating ends are also the spray end 51 and the coupling end 52. Compared with the second mode, a threaded locking method is also used to combine the coupling end 52 with the outlet of the spray gun 10, and the spray head 50 is used to enhance the spraying function. The branch pipe 53 connects the spray head 50 and the lid 54 together, so that the container 55 is detachably combined under the lid 54.

The difference is that the fourth mode has an additional foam generator 56. One end of the foam generator 56 is connected to the spray head 50 and the other end serves as the spray end 51. In other words, the foam generator 56 is connected between the spray end 51 of the spray head 50 and the branch pipe 53. When the spray gun 10 draws and mixes the solution in the container 55 into a high-pressure fluid, the foam generator 56 will not only reduce the flow rate, but also spray the foam on the surface of vehicles and other objects, which is also suitable for maintenance and maintenance work.

As shown in FIG. 7, the spray head 60 is in the fifth mode, and its two communicating ends are also the spray end 61 and the coupling end 62. Compared with the second mode, a nut 63 is also locked on the front end of the spray head 60 to serve as the spray end 61. The threaded locking means is used to connect the coupling end 62 to the outlet of the spray gun 10, and the spray head 60 is used to enhance the spray effect.

The difference is that a joint 64 connects the spray head 60 and a hose 65 together, and the joint 64 is equipped with a one-way valve 66 to operate the flow of the fluid flowing to the spray head 60 through the hose 65. The fluid generally refers to cleaning agents, brighteners or waxy substances. The mixed high-pressure fluid flows out of the spray end 61 of the spray head 60, which is also suitable for the maintenance and maintenance of vehicles and other items.

Without departing from the broad concept of this case, those who are familiar with this technology can understand and make changes to the above-opened embodiments. Therefore, this case is not limited to the specific embodiments disclosed in the specification, and all modifications made in accordance with the spirit and technical scope of the case should be covered and protected by the text defined in the scope of the patent application.
