Description

Technical Field

[0001] This utility model relates to the field of nozzle technology, specifically a pressure cleaning nozzle. Background Technology

[0002] Car wash nozzles are key equipment in the car maintenance process, primarily used to connect high-pressure water hoses and convert water flow into different spray patterns to meet the cleaning needs of various parts of the vehicle. Existing nozzle products are typically made of metal or engineering plastics, using a precisely designed internal flow channel structure to atomize or concentrate the water flow. Standard nozzles connect to high-pressure water hoses via threaded interfaces, offering a certain degree of sealing and durability, making them essential tools for car detailing and repair shops.

[0003] Current car washer nozzles suffer from two prominent problems: First, the nozzles are easily clogged by scale or impurities, requiring complete disassembly for cleaning. Traditional threaded connections necessitate multiple rotations, making the disassembly process cumbersome and time-consuming. Second, frequent disassembly and reassembly can lead to thread wear, affecting sealing performance and causing leaks. These problems not only reduce cleaning efficiency but also shorten the nozzle's lifespan. Therefore, we propose a pressure cleaning nozzle. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a pressure cleaning nozzle that can be quickly disassembled, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure cleaning nozzle, comprising a connecting pipe and a water outlet assembly;

[0006] Connecting pipe: A filter assembly is installed at the right end inside the connecting pipe, a support assembly is installed on the circumferential surface of the connecting pipe, and a fixing assembly is installed at the right end of the support assembly;

[0007] Water outlet assembly: includes a sleeve, a water outlet head, a clamping plate, and a distance sensor. The right end of the circumference of the connecting pipe has evenly distributed grooves, and the clamping plates are clamped inside the grooves. The sleeves are fixed to the surfaces of all the clamping plates. The water outlet head is fixed to the right end inside the sleeve. The right end of the filter assembly is installed at the left end inside the sleeve. The fixing assembly is connected to all the clamping plates. The right end of the sleeve has a groove, and the distance sensor is installed inside the groove. The distance sensor is bidirectionally electrically connected to an external PLC controller. Water is discharged by setting up the water outlet assembly.

[0008] Furthermore, the support assembly includes a fixing ring, a connecting ring, anti-slip grooves, and a torsion spring. The fixing ring is fixed on the circumferential surface of the connecting tube, and the connecting ring is sleeved on the circumferential surface of the connecting tube. The connecting ring has evenly distributed anti-slip grooves on its circumferential surface, and the torsion spring is sleeved on the circumferential surface of the connecting tube. The left end of the torsion spring is fixed to the right end of the fixing ring, and the right end of the torsion spring is fixed to the left end of the connecting ring. The support assembly supports all the connecting plates.

[0009] Furthermore, the fixing component includes a connecting plate and a clamping head. The right end of the connecting ring is fixed with evenly distributed connecting plates, and the side of the connecting plate is fixed with a clamping head. The side of the clamping plate is provided with a clamping hole, and the clamping head is engaged inside the clamping hole. All the clamping plates are fixed by setting evenly distributed clamping heads.

[0010] Furthermore, the filter assembly includes a support ring, a filter screen, and a fastening ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This pressure cleaning nozzle has the following advantages:

[0013] 1. By combining the snap-fit ​​structure with the spring linkage assembly, the water outlet assembly can be disassembled with one click, which greatly simplifies the multi-step operation of traditional threaded connections, significantly improves maintenance efficiency, avoids mechanical wear caused by repeated disassembly and assembly, and ensures long-term sealing reliability.

[0014] 2. It adopts an axial clamping filter screen design, combined with an elastic sealing structure, to achieve self-adaptive sealing under high pressure while filtering impurities, effectively preventing leakage. The filter component can be disassembled synchronously with the water outlet component, which is convenient for quick cleaning or replacement.

[0015] 3. The torsion spring and anti-slip structure of the support components provide operating damping to prevent accidental loosening, while the deformation compensation capability of the sealing rubber ring can offset the minor deformation caused by the impact of high-pressure water flow, enhance the overall structural stability, and extend the service life of the nozzle.

Detailed Implementation

[0020] Please see Figure 1-3 A pressure cleaning nozzle includes a connecting pipe 1 and a water outlet assembly 2;

[0021] Connecting pipe 1: A filter assembly 5 is installed at the right end inside. A support assembly 3 is installed on the circumference of the connecting pipe 1. A fixing assembly 4 is installed at the right end of the support assembly 3. The support assembly 3 includes a fixing ring 31, a connecting ring 32, an anti-slip groove 33, and a torsion spring 34. The fixing ring 31 is fixed on the circumference of the connecting pipe 1. The connecting ring 32 is sleeved on the circumference of the connecting pipe 1. The connecting ring 32 has evenly distributed anti-slip grooves 33 on its circumference. The torsion spring 34 is sleeved on the circumference of the connecting pipe 1. The left end of the torsion spring 34 is fixed to the right end of the fixing ring 31. The right end of the torsion spring 34 is fixed to the left end of the connecting ring 32. The fixing assembly 4 includes a connecting plate 41 and a clamp 42. The right end of the connecting ring 32 is fixed... The filter assembly 5 includes a uniformly distributed connecting plate 41, a clip 42 fixed on the side of the connecting plate 41, and a clip hole on the side of the clip plate 23. The clip 42 is clipped into the inside of the clip hole. The filter assembly 5 includes a support ring 51, a filter screen 52 and a fastening ring 53. The right end of the inside of the connecting pipe 1 is fixed with the support ring 51. The right end of the support ring 51 is provided with the filter screen 52. The right end of the filter screen 52 is provided with the fastening ring 53. The fastening ring 53 is fixed inside the sleeve 21. The left end of the fastening ring 53 is attached to the right end of the connecting pipe 1. The filter assembly 5 is used to filter water. The clips 42 are evenly distributed and fixed to all the clip plates 23. The support assembly 3 is used to support all the connecting plates 41.

[0022] Water outlet assembly 2 includes a sleeve 21, a water outlet head 22, a clamping plate 23, and a distance sensor 24. The right end of the circumference of the connecting pipe 1 has evenly distributed grooves, and the clamping plate 23 is clamped inside the grooves. The sleeve 21 is fixed to the surface of all the clamping plates 23. The water outlet head 22 is fixed to the right end inside the sleeve 21. The right end of the filter assembly 5 is installed inside the left end of the sleeve 21. The fixing assembly 4 is connected to all the clamping plates 23. The right end of the sleeve 21 has a groove, and the distance sensor 24 is installed inside the groove. The distance sensor 24 is bidirectionally electrically connected to an external PLC controller (or Bluetooth connection can be used). Water is discharged by setting the water outlet assembly 2.

[0023] Wherein: the right end of the connecting pipe 1 is provided with an annular connecting groove, and a sealing rubber ring 6 is fixed inside the annular connecting groove. The left end of the fastening ring 53 is provided with an annular slot, and the sealing rubber ring 6 is snapped into the annular slot. The gap between the connecting pipe 1 and the sleeve 21 is sealed by setting the sealing rubber ring 6.

[0024] During operation, the water pipe is connected to the connecting pipe 1. After connection, the high-pressure water flow enters from the left end of the connecting pipe 1. First, it passes through the filter screen 52 of the filter assembly 5 to intercept impurities. The filtered water flow is then guided through the sleeve 21 to the water head 22 to form a jet of water. The distance sensor 24 monitors the distance signal between the nozzle and the cleaning surface in real time. The PLC controller dynamically adjusts the water supply system pressure: when the detected spray distance is lower than the safety threshold, the PLC controller automatically reduces the water pressure to scatter the water flow and prevent the high-pressure water flow from accidentally splashing onto the human body; when the distance returns to the normal range, the set water pressure is automatically restored to ensure the cleaning force. The filter screen 52 is axially clamped and fixed by the support ring 51 and the fastening ring 53, and a dynamic seal is achieved by the engagement of the sealing rubber ring 6 and the annular groove to ensure no leakage under high pressure. When disassembly and cleaning are required, the user holds the connecting ring 32 and rotates it, causing the clamp 42 of the fixing component 4 to disengage from the clamping hole of the clamping plate 23. At this time, the torsion spring 34 is compressed and stores energy, and the clamping plate 23 is released from the clamping groove of the connecting pipe 1, allowing the water outlet component 2 to be quickly pulled out to clear blockages. Assembly is performed in reverse: after the clamping plate 23 is inserted into the clamping groove, the connecting ring 32 is released, and the torsion spring 34 rebounds, driving the clamp 42 to automatically lock, quickly completing disassembly and assembly. The support component 3, through the elastic linkage between the fixing ring 31 and the connecting ring 32, provides damping during operation to prevent accidental contact. Simultaneously, the deformation compensation tolerance of the sealing rubber ring 6 ensures the structural stability of the nozzle under high-pressure impact, preventing leakage.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
