Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and in particular to a high-pressure cleaning device. Background Technology

[0002] High-pressure air cleaning technology, as a dry cleaning method, is widely used in scenarios where electronic equipment, precision machinery, optical components, and industrial parts are sensitive to water or have high cleanliness requirements. By pressurizing compressed air and spraying it at high speed through nozzles, it can effectively blow away and remove dust, debris, oil, and other contaminants adhering to the target surface.

[0003] However, most existing high-pressure air cleaning devices have nozzles with only a central hole, resulting in a concentrated, linear airflow pattern that cannot cover large cleaning areas or complex-shaped surfaces. This can easily lead to cleaning dead zones and affect cleaning effectiveness. The single-hole direct-jet structure causes the airflow impact force to be too concentrated in front of the nozzle, resulting in uneven airflow distribution and concentrated impact force, which cannot achieve uniform and effective cleaning.

[0004] Therefore, a high-pressure cleaning device is urgently needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure cleaning device that can form a high-pressure diffusion airflow at the nozzle, significantly expanding the airflow coverage area and improving the uniformity of airflow distribution.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0008] The main body is provided with an air channel, which has an air inlet and an air outlet;

[0009] A switching valve is disposed on the main body, and the switching valve is used to connect or disconnect the air inlet and the air outlet;

[0010] A nozzle is disposed at the air outlet and is detachably connected to the main body. The nozzle has a central hole and multiple opening slots. The multiple opening slots extend along the axial direction of the nozzle and are arranged circumferentially at intervals on the outer peripheral wall of the nozzle. An air outlet gap is formed between the opening slots and the inner wall of the air channel.

[0011] Along the flow direction of the gas in the air channel, the diameter of the central hole gradually decreases, and the radial depth of the opening groove in the nozzle gradually decreases.

[0012] Optionally, the cross-section of the opening groove is rectangular, trapezoidal, or semi-circular.

[0013] Optionally, the high-pressure cleaning device further includes an air extension tube, one end of which can be connected to the air outlet, and the other end is provided with the nozzle.

[0014] Optionally, the air extension tube is snap-fitted or threaded to the main body.

[0015] Optionally, the nozzle is threadedly connected to the air extension pipe.

[0016] Optionally, the high-pressure cleaning device further includes a noise-reducing protective tube, which is disposed at the end of the air extension tube away from the main body, and is used to reduce the audio frequency of the nozzle to a preset range.

[0017] Optionally, the sound-absorbing protective pipe includes a pipe body, and the peripheral wall of the pipe body is evenly distributed with a plurality of sound-absorbing holes.

[0018] Optionally, the switching valve includes:

[0039] This embodiment provides a high-pressure cleaning device, such as... Figures 1-4 As shown, the high-pressure cleaning device includes a main body 100, a switching valve 200, and a nozzle 300. The main body 100 has an air passage with an inlet 110 and an outlet. The switching valve 200 is mounted on the main body 100 and is used to connect or disconnect the inlet 110 and the outlet. The nozzle 300 is located at the outlet and is detachably connected to the main body 100. The nozzle 300 has a central hole 310 and multiple opening slots 320, all along the axial direction of the nozzle 300. Extending and spaced circumferentially on the outer peripheral wall of the nozzle 300, the opening groove 320 forms an air outlet gap with the inner wall of the air channel. Along the flow direction of the gas in the air channel, the diameter of the central hole 310 gradually decreases, and the radial depth of the opening groove 320 in the nozzle 300 gradually decreases. This can form a high-pressure diffusion airflow at the nozzle 300, significantly expanding the airflow coverage area, allowing the airflow to be ejected in an umbrella shape, improving the uniformity of airflow distribution, reducing cleaning blind spots, and thus effectively improving the cleaning effect and cleaning efficiency.

[0040] Optionally, such as Figures 2-3 As shown, the cross-section of the opening groove 320 is rectangular, trapezoidal, or semi-circular. A rectangular cross-section facilitates the manufacturing of the opening groove 320 and allows the nozzle 300 to form a stable and uniform airflow channel. A trapezoidal cross-section guides the airflow gradually towards the nozzle 300 outlet, improving airflow diffusion. A semi-circular cross-section helps reduce edge airflow resistance, resulting in a smoother airflow transition and reduced turbulence, thereby further improving the stability of the airflow output and the uniformity of cleaning coverage of the nozzle 300. The cross-sectional shape of the opening groove 320 can be flexibly set according to actual cleaning needs.

[0041] Optionally, such as Figure 1 and Figure 4As shown, the high-pressure cleaning device also includes an air extension tube 400. One end of the air extension tube 400 can be connected to the air outlet, and the other end is equipped with a nozzle 300. By setting the air extension tube 400, the nozzle 300 can be extended into a narrow space to carry out cleaning operations, which significantly improves the adaptability of the high-pressure cleaning device to cleaning complex structures or small spaces and improves the cleaning effect.

[0042] Optionally, the air extension tube 400 is snap-fitted or threaded to the main body 100. Specifically, one end of the air extension tube 400 has an external thread on its outer circumference, and the air outlet of the main body 100 has a corresponding matching internal thread on its inner circumference. The two are connected by threaded engagement, and after tightening, a reliable mechanical fixation and airtight connection can be formed to prevent loosening or leakage under the action of high-pressure airflow.

[0043] In other embodiments, the air outlet of the main body 100 is provided with multiple circumferentially spaced claw structures. One end of the air extension tube 400 connected to the main body 100 is provided with an annular limiting flange. When the air extension tube 400 is inserted into the limiting position within the air outlet of the main body 100, the claw structures automatically engage behind the annular limiting flange, forming a locking connection. Optionally, the claw structure includes a claw and an elastic element. The middle part of the claw is rotatably connected to the main body 100. A spring is provided between the first end of the claw and the main body 100, and a hook is provided at the second end of the claw, which can hook onto the annular limiting flange.

[0044] Optionally, the nozzle 300 can be threaded to the body 100, which not only facilitates the installation, replacement and maintenance of the nozzle 300, but also allows for the quick replacement of different types of nozzles 300 according to different cleaning scenarios, in order to adapt to the needs of different cleaning intensities, spray angles or coverage areas.

[0045] It should be noted that when the air extension tube 400 is installed, the nozzle 300 is threadedly connected to the air extension tube 400. The threaded connection has good sealing and shock resistance stability, which can ensure that the high-pressure airflow does not leak or loosen during operation, improve the safety and stability of the device, and extend the service life of the high-pressure cleaning device.

[0046] Optionally, the high-pressure cleaning device also includes a noise reduction and protection pipe 500, which is located at the air outlet. The noise reduction and protection pipe 500 is used to reduce the audio frequency of the nozzle 300 to a preset range, significantly reducing noise pollution during operation and improving the comfort and safety of the operating environment.

[0047] In other implementations, when the high-pressure cleaning device is equipped with an air extension pipe 400, a noise reduction and protection pipe 500 is located at the end of the air extension pipe 400 away from the main body 100. The noise reduction and protection pipe 500 is used to reduce the audio frequency of the nozzle 300 to a preset range, so as to achieve effective noise reduction while extending the working distance, and ensure the comfort and safety of cleaning operations in complex working scenarios.

[0048] Optionally, such as Figure 4 As shown, the noise-absorbing protective tube 500 includes a tube body 510, and the peripheral wall of the tube body 510 is evenly distributed with multiple noise-absorbing holes 520. Through the porous structure, the sound wave energy brought by the high-speed airflow can be effectively dispersed and absorbed, further improving the noise reduction effect and reducing noise interference to the surrounding environment and operators. It is especially suitable for use in precision production or experimental environments with high noise control requirements.

[0049] Optionally, the switching valve 200 includes a sliding rod 210 and a handle 220. The sliding rod 210 is slidably disposed within the main body 100, with at least a portion of the sliding rod 210 protruding from the main body 100. The handle 220 is rotatably disposed on the main body 100, and is hinged to the portion of the sliding rod 210 protruding from the main body 100. The handle 220 is used to drive the sliding rod 210 to slide relative to the main body 100, thereby connecting or closing the air inlet 110 and the air outlet. Operators can conveniently control the switch via the external handle 220, improving operational safety and convenience.

[0050] Optionally, the switch valve 200 also includes a torsional elastic element. The handle 220 is rotatably connected to the main body 100 via a rotating shaft. The torsional elastic element is sleeved on the rotating shaft. One end of the torsional elastic element abuts against the main body 100, and the other end abuts against the handle 220. The torsional elastic element is used to provide elastic force to the handle 220 so that when the user does not press the handle 220, it drives the handle 220 to remain in the closed position, effectively preventing misoperation or accidental airflow leakage, and improving the safety, reliability and ease of operation of the high-pressure cleaning device.

[0051] Optionally, the nozzle 300 has at least two grooves 330 at the end opposite to the main body 100. The two grooves 330 are radially opposite each other along the central hole 310, and the two grooves 330 can be used with external specialized tools. By matching the grooves 330 with specialized tools, the ease of assembly and disassembly of the nozzle 300 is significantly improved, making maintenance and replacement easier, reducing operation time and labor costs, and improving the practicality and maintenance efficiency of the device.

[0052] Optionally, the nozzle 300 can be made of stainless steel, aluminum alloy, or alloy steel. Stainless steel nozzles 300 offer excellent corrosion resistance and durability, significantly extending their service life. Aluminum alloy nozzles 300 are lightweight and have good thermal conductivity, making them easy to process and use. Alloy steel nozzles 300 are high-strength and wear-resistant, suitable for high-intensity cleaning applications. The material of the nozzle 300 can be selected according to actual cleaning needs to extend its service life.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
