Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaner technology, specifically to a nozzle adjustment assembly for a high-pressure cleaner. Background Technology

[0002] A high-pressure washer is a device that uses high-pressure water jets for cleaning. It achieves efficient cleaning by pressurizing atmospheric water and creating a high-speed jet through nozzles. The nozzle is a crucial component of the high-pressure washer, directly affecting its cleaning efficiency and performance.

[0003] The water pressure of existing high-pressure cleaners is usually adjusted by a pump to change the water pressure sprayed onto the nozzle. However, using a pump for adjustment is costly and the system is relatively complex. Therefore, when the output water pressure is constant, the characteristics of the jet and the water flow can be changed by changing the nozzle diameter to achieve more precise control of the water pressure. However, most nozzle diameters are fixed and cannot be changed, so a nozzle that can change the intensity of the water output is needed. Utility Model Content

[0013] (III) Beneficial Effects

[0014] The advantages of this utility model compared with the prior art are as follows:

[0015] By controlling the components, rotating the knob drives the rotating tube to rotate. Since the rotating tube and the screw are threadedly connected, the rotation of the rotating tube drives the screw and the adjusting plug to move axially, changing the gap between the adjusting plug and the water outlet hole on the fixed plate, thereby changing the water outlet diameter and controlling the water output intensity. The overall structure is simple and the maintenance cost is low. Attached Figure Description

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Combined with appendix Figures 3 to 5 As shown, a nozzle adjustment assembly for a high-pressure washer includes a nozzle body 1. A fixing plate 2 is located on one side of the nozzle body 1 near the water outlet. The fixing plate 2 has a plurality of water outlet holes 3 arranged in an array. An adjustment assembly for adjusting the water output intensity is provided inside the nozzle body 1. The adjustment assembly includes an adjustment plug 4 rotatably disposed inside the nozzle body 1. One end of the water outlet of the nozzle body 1 has a conical structure, and the adjustment plug 4 is a frustoconical structure adapted to the interior of the nozzle body 1. One end of the adjustment plug 4 is connected to a screw 5. A protective shell 7 is connected to the inner wall of the nozzle body 1 via a connecting shell 6. A rotating tube 8 is rotatably connected inside the protective shell 7. The screw 5 is threadedly connected to the rotating tube 8. A control assembly for driving the rotating tube 8 to rotate is provided inside the nozzle body 1.

[0028] Among them, the combination of appendix Figure 5 and Figure 6 As shown, the control component includes a bevel gear 9 fixed on the rotating tube 8. The bevel gear 9 is located inside the protective shell 7. The nozzle body 1 is provided with a through hole 11 that communicates with the connecting shell 6. A rotating rod 12 is rotatably provided in the through hole 11. One end of the rotating rod 12 is connected to a bevel gear 10 that meshes with the bevel gear 9, and the other end is connected to a knob 16.

[0029] When it is necessary to change the water pressure sprayed from the nozzle, simply turn the knob 16. The knob 16 drives the rotating rod 12 to rotate. Through the meshing of bevel gear 9 and bevel gear 10, the vertical rotation is converted into the horizontal rotation of the rotating tube 8. Since the rotating tube 8 and the screw 5 are threadedly connected, when the knob 16 is turned, the screw 5 can be driven to rotate to change the distance between the adjusting plug 4 and the water outlet 3. When the adjusting plug 4 moves towards the fixed plate 2, the nozzle outlet diameter becomes smaller, resulting in a larger water pressure and a stronger water flow. Similarly, when the adjusting plug 4 moves away from the fixed plate 2, the water pressure and the water flow intensity decrease.

[0030] Combined with appendix Figure 4 and Figure 5 As shown, one end of the screw 5 located inside the rotating tube 8 is connected to a limiting plate 13. The outer diameter of the limiting plate 13 is the same as the inner diameter of the rotating tube 8. The limiting plate 13 can restrict the movement range of the screw 5 and prevent it from detaching from the rotating tube 8. A sealing ring is provided at the connection between the rotating tube 8 and the protective shell 7. The sealing ring can reduce the probability of water entering the protective shell 7. The end of the rotating tube 8 away from the adjusting plug 4 has an arc-shaped structure, which can reduce the impact force of water flow on the rotating tube 8. The nozzle body 1 and internal components are all made of stainless steel, which can reduce the probability of rust and extend the service life.

[0031] To improve cleaning efficiency, combined with the attached Figure 1 and Figure 2 As shown, a filter head 14 is threadedly connected to one end of the nozzle body 1 at the water outlet. The filter head 14 has several filter holes 15 with a diameter smaller than that of the water outlet 3. The filter head 14 can filter and remove impurities in the water, preventing impurities from washing away the items to be cleaned. The threaded connection of the filter head 14 makes it easy to disassemble and clean.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
