Description

Technical Field

[0001] This utility model relates to the field of industrial cleaning, and in particular to a detachable cavitation jet cleaning head. Background Technology

[0002] Cavitation jet cleaning technology is widely used in industrial cleaning and other fields requiring efficient surface cleaning. Its core principle is to utilize high-pressure water flow to generate cavitation bubbles under specific conditions. When these bubbles burst, they release a powerful impact force, thereby removing dirt and impurities from the surface of objects, achieving excellent cleaning results. The cavitation jet cleaning head, as a key component of this technology, plays a crucial role in converting high-pressure water flow into a jet with cavitation effects, effectively rinsing and cleaning the target area. Its structural design and performance directly affect the quality and efficiency of the entire cleaning operation.

[0003] Common cleaning heads typically employ a relatively fixed structure. Their nozzles are usually connected to the water supply lines of the pan body via welding, strong adhesive bonding, or complex threaded fastening, forming a relatively inseparable integrated structure. The existing technology has the following drawbacks: the nozzles are connected by welding, bonding and other methods, which makes disassembly and assembly extremely inconvenient. Once the nozzles become clogged or worn and need to be replaced or repaired, it often takes a lot of time and manpower to disassemble the original connection. In fact, improper disassembly may damage other parts of the head, increasing maintenance costs and difficulty, and prolonging the downtime of the entire cleaning operation. Therefore, a detachable cavitation jet cleaning head is proposed to solve the above problems. Summary of the Invention

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1-3This utility model provides an embodiment of a detachable cavitation jet cleaning head, comprising a disc 1, with an installation pipe 2 extending through the inner wall of the disc 1. The installation pipe 2 is an existing pipe that allows water to be delivered to a fixed pipe 3 and a nozzle 6. A fixed pipe 3 is fixedly connected to the side wall of the installation pipe 2, and a circular block 4 is fixedly connected to the top of the fixed pipe 3. The circular block 4 is hollow inside and can accommodate the rotation of a rotating rod 7 and the placement of a torsion spring 5. The inner wall of the circular block 4 is elastically connected to the rotating rod 7 via the torsion spring 5. A fixing block 8 is fixedly connected to the outer wall of the rotating rod 7, and a connecting mechanism is provided on the outer wall of the rotating rod 7. A nozzle 6 is inserted into the inner wall of the fixed pipe 3, and the nozzle 6 can deliver high-pressure water. The water jets out at high speed, and the water flow generates a large number of tiny cavitation bubbles due to pressure changes during the movement. An L-plate 12 is fixedly connected to the top of the nozzle 6. The L-plate 12 is hollow in the middle, and the diameter of the hollow is the same as that of the rotating rod 7. A positioning tube 13 is fixedly connected to the side wall of the mounting tube 2. The inner wall of the positioning tube 13 has a groove, which allows the connector 17 to slide along the groove. The groove and the connector 17 use existing sealing materials to prevent water from leaking from the connector 17 and the positioning tube 13. The connector 17 is slidably connected to the inner wall of the positioning tube 13. The right end of the connector 17 is threaded, which allows the connector 17 to be connected to an external pipe. A buffer component is provided at the top of the positioning tube 13.

[0019] The connecting mechanism includes a connecting block 10, which is slidably connected to the outer wall of the rotating rod 7. The outer wall of the rotating rod 7 has a slot, and the inner wall of the connecting block 10 has a matching protrusion, which allows the connecting block 10 to move vertically along the slot and also allows the connecting block 10 to rotate with the rotating rod 7. The inner wall of the top of the connecting block 10 is elastically connected to the rotating rod 7 through a return spring 9, and the bottom end of the connecting block 10 is fixedly connected to an insert block 11.

[0020] Reference Figure 1 , Figure 5 and Figure 6 The buffer assembly includes a sleeve 14 with a circular hole that allows air to enter and exit. The sleeve 14 is fixedly connected to the top of the positioning tube 13. The piston tube 16 is elastically connected to the inner wall of the left end of the sleeve 14 via a positioning spring 15. A protrusion 18, made of rubber, is fixedly connected to the inner wall of the sleeve 14 to provide resistance during the movement of the piston tube 16. The inner wall of the left end of the sleeve 14 is fixedly connected to one end of the positioning spring 15. When the piston tube 16 moves to the left, it compresses the positioning spring 15. When the piston tube 16 moves to the right, it stretches the positioning spring 15. During reset, the positioning spring 15 uses its own elasticity to reset the piston tube 16 to its initial state. The other end of the positioning spring 15 is fixedly connected to the left side wall of the piston tube 16. The piston tube 16 passes through and is connected to the inner wall of the sleeve 14. The piston tube 16 is fixedly connected to the top of the connector 17. The bottom end of the piston tube 16 is in contact with the surface of the protrusion 18.

[0021] Reference Figures 2-4 The inner wall of the circular block 4 is fixedly connected to one end of the torsion spring 5. When the rotating rod 7 rotates, it will compress the torsion spring 5. When resetting, the elastic force of the torsion spring 5 will carry the rotating rod 7 back to its original position. The other end of the torsion spring 5 is fixedly connected to the outer wall of the rotating rod 7. The rotating rod 7 passes through and is rotatably connected to the inner wall of the circular block 4. The fixing block 8 is snapped into the inner side wall of the L plate 12. The inner side wall of the L plate 12 has a circular groove, which can block the fixing block 8. The insert block 11 is inserted into the top of the L plate 12. The L plate 12 has a slot corresponding to the insert block 11, which can satisfy the insertion of the insert block 11 into the slot and prevent the rotating rod 7 and the fixing block 8 from rotating.

[0022] Working principle: First, when quickly assembling or disassembling the nozzle 6, simply move the connecting block 10 upwards, moving the insert block 11 to separate the insert block 11 from the top groove of the L plate 12. Then, rotate the connecting block 10, rotating the rotating rod 7 and the fixing block 8, so that the fixing block 8 disengages from the inner side wall groove of the L plate 12, aligning the fixing block 8 laterally with the central opening of the L plate 12. At this point, move the L plate 12 to the right with the nozzle 6, disengaging the nozzle 6 from the fixing tube 3. During installation, simply rotate the fixing block 8 to the lateral position beforehand, allowing it to enter the opening of the L plate 12. After the fixing block 8 and the groove of the L plate 12 align, rotate the connecting block 10, using the spring force of the torsion spring 5 to reset the rotating rod 7 and the fixing block 8, allowing the fixing block 8 to be initially positioned in the groove of the L plate 12. Finally, release the connecting block 10, using the reverse spring force of the return spring 9 to insert the connecting block 10 and the insert block 11 into the top groove of the L plate 12.

[0023] When in use, the device can be connected to an external pipe via the threaded connector 17. When the water pressure suddenly increases, the connector 17 will drive the piston tube 16 to move to the left, compressing the positioning spring 15. At the same time, during the movement, it will be resisted by the rubber protrusion 18 on the inner wall of the sleeve 14. Through the elastic deformation of the positioning spring 15 and the resistance of the rubber protrusion 18, the pressure change is buffered, avoiding damage to the entire cleaning head due to sudden pressure changes. This also makes the water flow delivery more stable and ensures the stability of the spray from the nozzle 6. At the same time, when the piston tube 16 moves, it will compress the air inside the sleeve 14 and allow it to be discharged from the round hole. Conversely, when the water pressure decreases, the positioning spring 15 will rebound by its own elasticity, pushing the piston tube 16 to move to the right, so that the connector 17 returns to a relatively suitable position, which also plays a buffering and regulating role, maintaining the relative stability of the water pressure inside the entire cleaning head.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
