[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. Based on the embodiments of the utility model, all other embodiments obtained by users of the technology in this field without creative work belong to the protection scope of the utility model.

[0045] refer to Figures 1 to 4 This embodiment provides a cleaning water gun head, including a joint 1, a fixed tube 2 is arranged on the joint 1, a nozzle 3 is arranged in the fixed tube 2, and the nozzle 3 is rotatably connected in the fixed tube 2;

[0046] A rotating connecting pipe 4 is provided between the joint 1 and the nozzle 3, and the rotating connecting pipe 4 is rotatably connected to the fixed cylinder 2;

[0047] The joint 1 is connected to the nozzle 3 through the rotating connecting pipe 4 , and the nozzle 3 is detachably connected to the rotating connecting pipe 4 .

[0048] The nozzle 3 can be made of metal materials, such as stainless steel, etc. The fixed cylinder 2 and the joint 1 can be made of materials such as aluminum alloy.

[0049] The nozzle 3, the fixed tube 2 and the joint 1 should all have good corrosion resistance.

[0050] Specifically, the rotating connecting tube 4 is a copper tube. Copper material has good corrosion resistance, which prolongs the service life of the rotating connecting tube 4.

[0051] refer to Figures 1 to 4 , wherein: a rolling bearing 5 is arranged between the rotating connecting pipe 4 and the inner wall of the fixed cylinder 2.

[0052] There are at least two rolling bearings 5 ​​, and the rolling bearings 5 ​​are sleeved on the rotating connecting tube 4 .

[0053] The rolling bearing 5 has one.

[0054] There are four rolling bearings 5 ​​.

[0055] The first positioning solution of the rotating connecting tube 4: the inner ring of the rolling bearing 5 is interference fit with the rotating connecting tube 4, and the outer ring of the rolling bearing 5 is interference fit with the inner wall of the fixed tube 2. This solution can meet the positioning of the rotating connecting tube 4 and the nozzle 3 in the fixed tube 2 without setting other positioning structures, but this solution is inconvenient to operate during assembly or removal.

[0056] The second positioning scheme of the rotating connecting tube 4: the nozzle 3 includes a tube seat 31 located in the fixed tube 2 and a tube body 32 arranged on the tube seat 31, the tube seat 31 and the tube body 32 are an integrated structure, and the tube body 32 extends out of the fixed tube 2 in a direction away from the joint 1.

[0057] A retaining ring 21 is disposed at one end of the fixed tube 2 away from the joint 1 to prevent the pipe seat 31 from sliding out of the fixed tube 2 . The retaining ring 21 and the fixed tube 2 are an integrated structure.

[0058] After the rolling bearing 5 is sleeved on the rotating connecting tube 4, the inner ring of the rolling bearing 5 can be interference fit with the rotating connecting tube 4, and the outer ring of the rolling bearing 5 can be clearance fit with the inner wall of the fixed tube 2. This solution can not only realize the positioning of the rotating connecting tube 4, but also facilitate the removal of the rotating connecting tube from the fixed tube 2.

[0059] Alternatively, the inner ring of the rolling bearing 5 is clearance-matched with the rotating connecting tube 4, and a ring body is provided at one end of the rotating connecting tube 4 away from the tube seat 31 to prevent the rolling bearing 5 from sliding off, and the ring body can be an integrated structure with the rotating connecting tube 4. The ring body and the retaining ring 21 respectively position the two ends of the rolling bearing 5. In this case, the rolling bearing 5 is clearance-matched with the rotating connecting tube 4 and the fixed cylinder 2, and the rotating nozzle of the cleaning water gun is easy to assemble or disassemble.

[0060] The end surface of the rolling bearing 5 close to the retaining ring 21 contacts the retaining ring 21 , and the retaining ring 21 prevents the pipe seat 31 from sliding out of the fixed tube 2 through the rolling bearing 5 .

[0061] The pipe seat 31 is connected to the rotating connecting pipe 4 by threads, the pipe seat 31 is provided with internal threads, and the rotating connecting pipe 4 is provided with external threads.

[0062] Specifically: one end of the rotating connecting pipe 4 away from the nozzle 3 is provided with a water inlet hole matched with the joint 1 .

[0063] refer to Figures 1 to 4 The joint 1 is provided with a water supply nozzle 11 cooperating with the water inlet hole. The water inlet hole is a conical hole. The diameter of the end of the water inlet hole close to the nozzle 3 is smaller than the diameter of the end of the water inlet hole away from the nozzle 3.

[0064] The joint 1 and the water supply nozzle 11 are an integrated structure, and the joint 1 is connected to the fixed tube 2 by threads. The joint 1 is provided with an external thread, and the fixed tube 2 is provided with an internal thread. The end of the joint 1 away from the water supply nozzle 11 is provided with an external thread.

[0065] The external thread arranged at the end of the connector 1 away from the water supply nozzle 11 is used for connecting with a water pipe or a water gun.

[0066] The pipe seat 31 , the fixed cylinder 2 and the connecting nozzle 1 are all provided with a wrench clamping portion, so that the pipe seat 31 , the fixed cylinder 2 and the connecting nozzle 1 can be rotated by using a wrench.

[0067] Specifically: the nozzle 3 is provided with a first wrench clamping portion for facilitating the rotation of the nozzle 3. The first clamping portion is a clamping plane symmetrically arranged on the pipe seat 31.

[0068] The fixed barrel 2 is provided with a second wrench clamping portion for facilitating the rotation of the fixed barrel 2. The second wrench clamping portion is a clamping plane symmetrically arranged on the fixed barrel 2.

[0069] The joint 1 is provided with a third wrench clamping portion for facilitating the rotation of the joint 1, and a sealing ring is provided between the joint 1 and the fixed tube 2. The third wrench clamping portion is a clamping plane symmetrically arranged on the joint 1.

[0070] The working principle of this embodiment:

[0071] The fixed barrel 2 and the joint 1 do not rotate during use, and the nozzle 3 and the rotating connecting pipe 4 rotate relative to the fixed barrel 2 during use. The rotating connecting pipe 4 is only in contact with the joint 1 and is not fixed, so the nozzle 3 and the rotating connector 1 can rotate.

[0072] In the specific use process, taking the installation of the cleaning water gun head on the water gun as an example, the water gun can be installed on the kettle, and the water in the kettle is supplied to the nozzle 3 by the water gun. The specific water supply method can be that a water spray pipe can be arranged inside the rotating nozzle, one end of the water spray pipe extends into the kettle, and the other end of the water spray pipe extends out of the nozzle 3, and a jet channel is formed between the water spray pipe and the nozzle 3. Gas is supplied into the jet channel between the water spray pipe and the nozzle 3 through the water gun or other components, and the gas in the jet channel drives the nozzle 3 to rotate. The water spray pipe is used to spray water in the kettle.

[0073] The present utility model is not limited to the above optional implementation modes. Under the premise of not conflicting with each other, the various schemes can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present utility model. However, no matter what changes are made in their shapes or structures, all technical schemes that fall within the scope defined by the claims of the present utility model fall within the protection scope of the present utility model.
