DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] A preferred embodiment of a car washing liquid spray gun with a convenient nozzle replacement provided by the utility model is as follows: Figures 1 to 6 As shown: a car washing liquid spray gun which is easy to replace the spray head, comprises a gun body 1, a connecting pipe 2 is fixedly connected to the right side of the gun body 1, a rotating ring 3 is threadedly connected to the surface of the connecting pipe 2, a connecting pipe 4 is fitted inside the connecting pipe 2, a spray head body 5 is fixedly connected to the right side of the connecting pipe 4, a mounting ring 6 is fixedly connected to the surface of the spray head body 5, a connecting rod 7 is fixedly connected to one side of the mounting ring 6, a control ring 8 rotatably connected to the connecting pipe 2 is provided on one side of the rotating ring 3, a locking ring 10 is fixedly connected to one side of the control ring 8, and a stopper 9 fitted with the control ring 8 is fixedly connected to the surface of the connecting pipe 2.

[0030] In this embodiment, the connecting rod 7 is vertically arranged with respect to the mounting ring 6 , and the connecting rod 7 is equidistantly arranged in a circular shape with respect to the mounting ring 6 . By setting the connecting rod 7 , the connecting rod 7 can cooperate with the clamping ring 10 to fix the nozzle body 5 .

[0031] In this embodiment, a socket matching the size of the snap ring 10 is provided inside the connecting rod 7. The internal socket of the connecting rod 7 is located on the rotation trajectory of the snap ring 10. The internal socket of the snap ring 10 can fit tightly with the connecting rod 7, so that a gap exists between the two, causing the connecting rod 7 to loosen.

[0032] In this embodiment, the tail of the locking ring 10 is designed to be arc-shaped, and the control ring 8 forms a fixed structure through the rotating ring 3 and the block 9. When the locking ring 10 rotates counterclockwise, it will gradually slide out of the interior of the connecting rod 7. At this time, the connecting rod 7 will lose the fixing force of the locking ring 10, and the nozzle body 5 can be pulled outward, and the nozzle body 5 and the connecting pipe 4 can be pulled out from the interior of the connecting pipe 2.

[0033] In this embodiment, a rubber gasket is provided on the surface of the connecting tube 4, and the nozzle body 5 forms a fixed structure with the clamping ring 10 through the connecting tube 4. A rubber gasket is provided on the surface of the connecting tube 4, which can make it fit tightly with the inner wall of the connecting tube 2 to prevent leakage.

[0034] Example 2

[0035] Based on Example 1, a preferred embodiment of a car washing liquid spray gun that is easy to replace the nozzle provided by the utility model is as follows Figures 1 to 6 As shown: a sealing ring 11 is fixedly connected to the bottom of the gun body 1, a slot 12 is provided on the side of the sealing ring 11, a plug plate 13 is slidably connected inside the slot 12, an assembly plate 14 is fixedly connected to one side of the plug plate 13, a foam box 15 is placed inside the sealing ring 11, a conduit 16 communicating with the gun body 1 is connected to the top of the foam box 15, springs 17 are fixedly connected to both sides of the gun body 1, a limiting ring 18 fitted with the sealing ring 11 is fixedly connected to the bottom of the spring 17, a fixing slot 19 is provided on the inner wall of the limiting ring 18, a clamping plate 20 penetrating the slot 12 and embedded in the plug plate 13 is fitted on the inner wall of the fixing slot 19, and a handle 21 is fixedly connected to the bottom of the sealing ring 11.

[0036] In this embodiment, when the plug plate 13 is inserted into the sealing ring 11, the centers of the assembly plate 14 and the sealing ring 11 are located at the same point, and the inner walls of the sealing ring 11 and the assembly plate 14 are tightly fitted with the foam box 15. By setting the plug plate 13, when the plug plate 13 is inserted into the card slot 12, the assembly plate 14 and the sealing ring 11 can be snapped together.

[0037] In this embodiment, the assembly plate 14 forms a snap-fit ​​structure with the sealing ring 11 through the snap-fit ​​plate 20. The assembly plate 14 is designed as a transparent plastic plate. Since the assembly plate 14 is transparent, the user can check the remaining liquid level inside the foam box 15 through the assembly plate 14 at any time.

[0038] In this embodiment, the fixing groove 19 and the locking plate 20 are in a tightly fitted state, and the locking plate 20 is fixed by the fixing groove 19. The limiting ring 18 is pulled upward so that the fixing groove 19 is no longer in contact with the locking plate 20. Then the locking plate 20 is pulled out from the inside of the locking groove 12, and the assembly plate 14 can be removed from the inside of the sealing ring 11.

[0039] In this embodiment, a circular anti-skid groove is disposed on the surface of the handle 21 to prevent the handle 21 from slipping when the user holds it.

[0040] The working principle and use process of the utility model are as follows: first, when it is necessary to quickly disassemble the nozzle body 5, the rotating ring 3 can be slightly controlled to rotate so that it is no longer tightly fitted with the control ring 8. At this time, the control ring 8 can be rotated to drive the locking ring 10 to rotate counterclockwise. When the locking ring 10 rotates counterclockwise, it will gradually slide out of the interior of the connecting rod 7. At this time, the connecting rod 7 will lose the fixing force of the locking ring 10, and the nozzle body 5 can be pulled outward, and the nozzle body 5 and the connecting tube 4 can be pulled out from the interior of the connecting tube 2, so as to achieve the purpose of quickly disassembling and replacing the nozzle body 5, and the surface of the connecting tube 4 is provided with a rubber gasket, which can make it fit tightly with the inner wall of the connecting tube 2 to prevent leakage.

[0041] By setting the sealing ring 11, the sealing ring 11 can cooperate with the assembly plate 14 to hide the foam box 15 containing the car washing agent, thereby improving the visual integrity of the device and protecting the foam box 15. Since the assembly plate 14 is transparent, the user can check the remaining liquid level inside the foam box 15 through the assembly plate 14 at any time. When the liquid needs to be filled, the user only needs to pull the limiting ring 18 upward so that the fixing groove 19 no longer contacts the clamping plate 20, and then pull the clamping plate 20 out of the inside of the clamping groove 12, so that the assembly plate 14 can be removed from the inside of the sealing ring 11, and the foam box 15 can be taken out from under the conduit 16, and the inside can be treated with liquid increase. When the foam box 15 is placed inside the sealing ring 11, the sealing ring 11 will limit the foam box 15 together with the assembly plate 14 to prevent it from loosening from the conduit 16.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
