Description

Technical Field

[0001] This utility model belongs to the field of cleaning machine technology, and in particular to a universal multi-in-one high-pressure nozzle structure. Background Technology

[0002] A high-pressure washer uses a power unit to drive a high-pressure plunger pump to generate high-pressure water. The high-pressure water is then sprayed outward through the nozzle of the spray gun, hitting the surface of an object and peeling off and washing away dirt, thus achieving the purpose of cleaning the object's surface. It is mainly used for vehicle cleaning, exterior wall and floor cleaning, machine equipment cleaning, and workshop cleaning. During the cleaning process, the high-pressure water not only needs to be sprayed directly and vertically onto the object's surface, but also needs to be sprayed at an angle and the spray angle needs to be constantly adjusted to achieve a better cleaning effect.

[0003] Currently, the China Patent Network has published a nozzle rotation positioning mechanism for a spray gun handle [Authorization Announcement No.: CN209138990U]. This mechanism includes a handle, a gun barrel connected to the front end of the handle, a mounting base connected to the front end of the gun barrel, a connector seat connected to the front end of the mounting base, and a nozzle connected to the front end of the connector seat. The connector seat has a universal positioning connector on its head, with protruding teeth on its surface and arc-shaped grooves between the protruding teeth. A rotating base is connected to the rear end of the nozzle, and two universal joints (left and right) are mounted on the rotating base. The universal positioning connector is inserted between the two universal joints and is rotatably connected to the universal joints via a rotating shaft. An installation groove is formed in the rotating base, and a spring and a ejector pin are installed in the installation groove. The ejector pin has an arc-shaped head, and the spring pushes the ejector pin to engage with the arc-shaped groove. During use, when adjusting the spray angle of the nozzle, you can rotate the nozzle upwards or downwards with a little force by hand. The nozzle will drive the universal joint on the rotating seat to rotate around the rotating shaft. At the same time as the rotating seat rotates, the ejector pin in the mounting groove of the rotating seat engages with the arc-shaped tooth groove on the surface of the universal positioning joint. The arc-shaped tooth groove and the head of the ejector pin engage with the arc surface, allowing the ejector pin to overcome the spring force and retract into the mounting groove. With each rotation, the spring will push the ejector pin to return to its original position and pop out into the arc-shaped tooth groove. When the rotation is in place, release the nozzle by hand, and the ejector pin will be positioned in the arc-shaped tooth groove. If no external force is applied to rotate the nozzle, the nozzle will remain at that angle.

[0004] The above-mentioned nozzle rotation has the following drawbacks: the nozzle can only rotate back and forth in one direction, the rotation direction is relatively simple, which makes the direction adjustment of the nozzle simple and the direction adjustment range limited, and this direction adjustment structure is relatively complex. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a universal multi-functional high-pressure nozzle structure. The technical problem this invention aims to solve is: how to address the issue of the single direction adjustment of existing nozzles.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A multi-purpose high-pressure nozzle structure includes a gun barrel and a nozzle. The nozzle has a connecting rod, and the connecting rod has a water flow channel. The gun barrel has a omnidirectional ball at its front end, which can rotate in any direction. A portion of the omnidirectional ball is located outside the front end of the gun barrel. The omnidirectional ball has a second water flow channel that runs through the gun barrel. The connecting rod is inserted into the second water flow channel and is fixedly connected to the omnidirectional ball. The nozzle is a multi-purpose high-pressure nozzle, comprising a front shell and a rear shell. The front shell contains two or more nozzles. The front shell and rear shell are connected by screws and can rotate relative to each other. When the front shell rotates, the nozzles inside the front shell rotate together with the front shell, thereby causing the nozzle to spray different water patterns.

[0008] High-pressure water inside the nozzle enters the second water flow channel, then the connecting rod, and then the nozzle, finally being sprayed outwards through the nozzle. The nozzle in this structure is fixed to a universal ball, allowing it to rotate in any direction. This also makes the water outlet direction of the nozzle omnidirectionally adjustable, significantly improving the nozzle's directional adjustment range.

[0009] In the aforementioned all-purpose high-pressure nozzle structure, the front end of the nozzle shaft has a water outlet cavity, and the omnidirectional ball portion is located within the water outlet cavity. A limiting sleeve is screwed onto the outer circumferential surface of the front end of the nozzle shaft. The front end of the limiting sleeve has an outwardly bent limiting flange, which fits against the front hemisphere of the omnidirectional ball. The limiting sleeve limits the omnidirectional ball, ensuring that the omnidirectional ball is movably installed at the front end of the nozzle shaft without detaching from it.

[0010] In the aforementioned universal multi-functional high-pressure nozzle structure, a sealing ring is fitted onto the outer spherical surface of the universal ball. The sealing ring is in close contact with the outer spherical surface of the universal ball, the inner circumferential surface of the limiting sleeve, and the front end face of the nozzle. The sealing ring ensures that the outer spherical surface of the universal ball, the inner circumferential surface of the limiting sleeve, and the front end face of the nozzle are in a sealed state, preventing water leakage.

[0011] In the aforementioned all-in-one high-pressure nozzle structure, the inner wall of the front end of the water outlet chamber has an arc-shaped mating surface, which fits against the outer spherical surface of the universal ball. The mating surface adapts to the outer spherical surface of the universal ball, ensuring smooth rotation of the universal ball in all directions.

[0012] In the aforementioned all-in-one high-pressure nozzle structure, the high-pressure nozzle structure further includes a protective sleeve, which is fitted onto the outer wall of the limiting sleeve. The front end of the protective sleeve has an inwardly bent front limiting flange that fits into a limiting flange. The rear end of the protective sleeve has an inwardly bent rear limiting flange. The nozzle barrel has a step, and the rear limiting flange fits into the step. The protective sleeve serves to protect the limiting sleeve and the front end of the nozzle barrel.

[0013] In the aforementioned universal multi-functional high-pressure nozzle structure, a sealing ring 2 is provided between the outer circumferential surface of the connecting rod and the inner circumferential surface of the water flow channel 2. The sealing ring 2 ensures a seal at the assembly point between the connecting rod and the universal ball joint.

[0014] In the aforementioned all-in-one high-pressure nozzle structure, the connecting rod is threadedly connected to the universal ball joint. The connection between the connecting rod and the universal ball joint is simple, convenient, and secure.

[0015] Compared with the prior art, the universal multi-in-one high-pressure nozzle structure of this utility model has the following advantages: the high-pressure water in the gun barrel enters the water flow channel two, then enters the connecting rod, and then enters the nozzle, and finally sprays out through the nozzle. The nozzle is fixed on the universal ball, so the nozzle can rotate in all directions, that is, the nozzle can rotate in any direction, and the water outlet direction of the nozzle can also be rotated in all directions, which significantly improves the direction adjustment range of the nozzle.

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] like Figure 1As shown, this multi-purpose high-pressure nozzle structure includes a gun barrel 1 and a nozzle 2. The nozzle 2 is a multi-purpose high-pressure nozzle with a connecting rod 3. The connecting rod 3 has a water flow channel 30. The front end of the gun barrel 1 is equipped with a universal ball 4 that can rotate in any direction. Part of the universal ball 4 is located outside the front end of the gun barrel 1. The universal ball 4 has a water flow channel 40 that runs through it. The connecting rod 3 is inserted into the water flow channel 40 and is fixedly connected to the universal ball 4. The connecting rod 3 and the universal ball 4 are threaded together. High-pressure water in the gun barrel 1 enters the water flow channel 40, then enters the connecting rod 3, and then enters the nozzle 2, finally being sprayed outward through the nozzle 2. In this structure, the nozzle 2 is fixed to the universal ball 4, so the nozzle 2 can rotate in all directions, that is, the nozzle 2 can rotate in any direction. The water outlet direction of the nozzle 2 can also be rotated in all directions, significantly improving the directional adjustment range of the nozzle 2. The nozzle 2 is a multi-function high-pressure nozzle, which includes a front housing 20 and a rear housing 21. The front housing 20 contains two or more nozzles 22. The front housing 20 and the rear housing 21 are connected by screws and can rotate relative to each other. When the front housing 20 is rotated, the nozzles 22 inside the front housing 20 rotate together with the front housing 20, thereby causing the nozzle 2 to spray out different water patterns.

[0020] like Figure 1 As shown, the front end of the gun barrel 1 has a water outlet cavity 5, and part of the universal ball 4 is located inside the water outlet cavity 5. The inner wall of the front end of the water outlet cavity 5 has an arc-shaped mating surface 50, which fits against the outer spherical surface of the universal ball 4. A limiting sleeve 6 is screwed onto the outer circumferential surface of the front end of the gun barrel 1. The front end of the limiting sleeve 6 has an outwardly bent limiting flange 60, which fits against the front hemisphere of the universal ball 4. The limiting sleeve 6 limits the universal ball 4, ensuring that the universal ball 4 is movably installed at the front end of the gun barrel 1, and that the universal ball 4 will not fall off the front end of the gun barrel 1.

[0021] like Figure 1 As shown, a sealing ring 7 is fitted onto the outer spherical surface of the universal ball 4. The sealing ring 7 is in close contact with the outer spherical surface of the universal ball 4, the inner circumferential surface of the limiting sleeve 6, and the front end face of the gun rod 1. A sealing ring 9 is provided between the outer circumferential surface of the connecting rod 3 and the inner circumferential surface of the water flow channel 40. The sealing ring 7 ensures that the outer spherical surface of the universal ball 4, the inner circumferential surface of the limiting sleeve 6, and the front end face of the gun rod 1 are in a sealed state to prevent water leakage; the sealing ring 9 ensures that the assembly between the connecting rod 3 and the universal ball 4 remains sealed.

[0022] like Figure 1As shown, this high-pressure nozzle structure also includes a sheath 8, which is fitted onto the outer wall of the limiting sleeve 6. The front end of the sheath 8 has an inwardly bent front limiting flange 80, which fits into the limiting flange 60. The rear end of the sheath 8 has an inwardly bent rear limiting flange 81. The gun barrel 1 has a step 100, and the rear limiting flange 81 fits into the step 100. The sheath 8 serves to protect the limiting sleeve 6 and the front end of the gun barrel 1.
