Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Embodiment 1: Refer to Figure 1 - Figure 4 , an angle-adjustable spray cleaning device for valve hard chromium plating, including a booster pump 1 for pressurizing the inside of the water box 5 of the present device to accelerate the water flow, and further including:

[0026] An anti-backflow component 2, the anti-backflow component 2 includes a water box 5, which is the part where water enters. One side of the water box 5 is butt-connected and installed with a water inlet pipe 4, and one side of the water inlet pipe 4 is butt-connected and installed with an adapter 6, and the adapter 6 part is used to achieve the effect of preventing backflow. The side wall of the adapter 6 is respectively provided with a chute 7 and a spring groove 19, and a guide rod 8 and a tension spring 9 are respectively arranged inside the chute 7 and the spring groove 19. The function of the guide rod 8 is that the movement of the wet cover plate 10 follows a certain track, and the function of the tension spring 9 is to cover and install the cover plate 10 on the surface of the adapter 6. The end parts of the guide rod 8 and the tension spring 9 are respectively connected and installed with a cover plate 10;

[0027] One side of the water box 5 is provided with a spray nozzle 11, which is the part where water is sprayed out.

[0028] An angle-adjustable spray cleaning device for valve hard chromium plating, the water box 5 is of a cylindrical structure, the booster pump 1 is connected and installed on one side of the water box 5 for applying pressure to the inside of the water box 5 to squeeze out water. A water tank 20 is arranged inside the water box 5.

[0029] An angle-adjustable spray cleaning device for valve hard chromium plating, the spray nozzle 11 is set as a conical tower-shaped closing structure, so that the flow rate of water increases when flowing out of the spray nozzle 11.

[0030] An adjustable-angle spray cleaning device for valve hard chromium plating, further comprising:

[0031] An angle adjustment assembly 3 for adjusting the installation angle of the water spraying assembly. The angle adjustment assembly 3 includes a rotating shaft 12 fixed to the side of the water box 5. The rotating shaft 12 is rotatably installed inside the side frame through a bearing 13, thereby realizing the angle change effect of the nozzle. A bearing 13 is installed on the surface of the rotating shaft 12, a side frame is installed outside the bearing 13, the contour size of the side frame is the same as that of the water box 5, and a knob 14 is installed on one side of the rotating shaft 12. The knob 14 is a direct angle adjustment assembly.

[0032] For an adjustable-angle spray cleaning device for valve hard chromium plating, the contour size of the side frame is the same as that of the water box 5, ensuring the integrity of the device. A gap is reserved between the side frame and the water box 5 to avoid frictional resistance during rotation.

[0033] For an adjustable-angle spray cleaning device for valve hard chromium plating, a bracket 15 is installed at the bottom of the side frame. The bracket 15 can slide on the surface of the slide plate 16. A slide plate 16 is installed on one side of the bracket 15, and a magnetic attraction plate 17 is arranged on the side of the slide plate 16.

[0034] For an adjustable-angle spray cleaning device for valve hard chromium plating, the magnetic attraction plate 17 and the slide plate 16 can adsorb each other to achieve the effect of adsorption installation. A guide groove 18 is arranged between the magnetic attraction plates 17. The function of the guide groove 18 is the part where the magnetic attraction plate 17 is slidably installed.

[0035] Working principle:

[0036] In the actual creation process of the present utility model, in order to avoid the following defects existing in the prior art: "In the prior art, in order to achieve the pressurization effect of the cleaning water, an air pump is directly introduced into the inside of the water tank, and the water pressure inside the water tank is increased to achieve the effect of spray cleaning. However, the water tank needs to be externally connected with a water inlet pipe as the water input. If the air pump air pressure is directly introduced into the inside of the water tank, there may be a risk of water backflow into the pipeline, thereby reducing the safety of the device." The anti-backflow assembly 2 and the angle adjustment assembly 3 are specifically proposed.

[0037] When adding water, the external water source enters the water tank 20 inside the adapter 6 through the water inlet pipe 4 for temporary storage. The water pressure will squeeze the end cover plate 10 to open the cover plate 10, and the water directly enters the inside of the water box 5, and cooperates with the pressurization effect of the booster pump 1 on the side to spray the water at high pressure from the spray port 11.

[0038] To avoid the problem of backflow at the inlet pipe 4 caused by excessive water pressure inside the water box 5 of the booster pump 1, we have made an improved design for the adapter 6: sliding grooves 7 and spring grooves 19 are respectively opened on the sides of the adapter 6 for slidably mounting the guide rod 8 and the tension spring 9, and the tension spring 9 and the guide rod 8 are respectively fixedly connected to the inner side of the cover plate 10. When water enters, the cover plate 10 overcomes the tension of the tension spring 9 and opens a certain space under the positioning and sliding action of the guide rod 8. Once a backflow phenomenon occurs, the tension spring 9 will drag the cover plate 10 immediately, so that the cover plate 10 seals and covers the surface of the water tank 20 to prevent the water flow from flowing backward; this setting directly avoids the backflow problem caused by the booster pump 1 and increases the intensity of the positive water pressure at the same time.

[0039] The rotating shaft 12 provided on the side of this device cooperates with the bearing 13 to achieve the angle adjustment effect on the side frame, and the bracket 15 at the bottom can slide inside the sliding groove 18 to achieve position adjustment. The magnetic attraction plate 17 can avoid the occurrence of the problem of slipping off and plays a certain positioning role.

[0040] Through the anti-backflow assembly 2 in which the booster pump 1 and the inlet pipe 4 are independent of each other provided by the present utility model, when water enters, the inlet pipe 4 pushes open the cover plate 10 to let water in; and when the internal air pressure is too high and backflow occurs, the cover plate 10 will seal and cover the surface of the water tank 20 under the action of the tension spring 9 and the guide rod 8. The water tank designed in this way directly avoids the occurrence of the backflow problem and indirectly improves the water pressure of the air pump, making the water spraying effect of the spray head better.

[0041] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
