Abstract
Description
Technical Field
[0001] This utility model relates to the field of cavitation jet technology, and in particular to a cavitation jet impactor. Background Technology
[0002] A cavitation jet impactor is a device that generates a high-energy jet by utilizing the cavitation effect. Liquid passes through a special nozzle, causing the local pressure to drop below the saturated vapor pressure, generating numerous cavitation bubbles. These bubbles collapse in the high-pressure zone, releasing enormous energy. This device focuses the cavitation jet towards the target object. In the machining field, it can cut metal materials with excellent cut quality and minimal heat-affected zone; it can also be used for metal surface cleaning and micro-etching. In the petroleum industry, it can clean scale from oil wells and tubing, unblocking blockages and increasing production. In the shipbuilding industry, it can clean and prevent fouling of ship hulls. In the construction industry, it can treat concrete surfaces, cleaning stains and roughening them to facilitate the adhesion of new coatings.
[0003] Existing cavitation jet impactors typically include a high-pressure water jet main channel, which serves as the jet delivery path; a multi-chamber cavitation high-pressure nozzle, a key component consisting of primary, secondary, and tertiary high-pressure nozzles, with each nozzle's unique shape and structure working together to generate the cavitation jet; a mobile trolley for supporting and moving related components; a high-pressure water jet generator providing a high-pressure power source; a ball valve controlling the water jet flow and pressure; and auxiliary components such as filters, pressure gauges, and safety valves to ensure stable, safe, and efficient operation of the impactor.
[0004] Existing technologies suffer from low water pressure and weak impact force in nozzle jets, posing numerous hazards. Cleaning guns struggle to remove dirt when cleaning vehicles, construction equipment, and large facilities, wasting time and manpower, and causing equipment rust and damage due to incomplete cleaning, shortening its lifespan. Cleaning trays are ineffective at removing grease and other contaminants when cleaning large areas or workshop floors, requiring repeated cleaning that is inefficient and costly, and residual stains can easily lead to safety accidents. Cleaning robots lack sufficient nozzle impact force to clean stains in smart home environments, failing to meet cleaning standards and reducing practicality and user satisfaction. Oral irrigators, therefore, cannot reach deep into the gaps between teeth and gingival sulci, resulting in incomplete cleaning, increasing the risk of oral diseases and threatening oral health. When cleaning aquariums, low water pressure cannot thoroughly remove algae and other debris from the tank walls, accelerating water quality deterioration, damaging the fish's living environment, and increasing the likelihood of fish diseases. Dishwashers, due to insufficient water pressure, struggle to clean grease and residue from dishes, requiring multiple cycles, wasting water and electricity, affecting food hygiene, and causing numerous inconveniences and potential hazards for families and the catering industry. Therefore, a cavitation jet impactor is proposed to solve these problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a cavitation jet impactor, which aims to improve the problem that the nozzles used in the prior art have a small water pressure, resulting in low cleaning quality during cleaning operations.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A cavitation jet impactor includes a water flow shell, characterized in that: a first connecting pipe is slidably connected to the top of the water flow shell, a nozzle shell is slidably connected to the top of the first connecting pipe, and an ejection assembly is disposed inside the nozzle shell;
[0008] The spraying assembly includes a rotating disk, the outer wall of which is rotatably connected to the inside of the nozzle housing. A second connecting pipe is fixedly connected inside the rotating disk, and a funnel-shaped nozzle is fixedly connected to the top of the second connecting pipe. A first hollow column is fixedly connected inside the rotating disk, and an inclined nozzle is fixedly connected to one end of the first hollow column. A rotating assembly is provided inside the nozzle housing.
[0009] As a further description of the above technical solution:
[0010] The rotating assembly includes a connecting shaft, the outer wall of which is rotatably connected to the inside of the nozzle housing, and the other side of the connecting shaft is rotatably connected to the inside of the first connecting tube;
[0011] As a further description of the above technical solution:
[0012] A support plate is fixedly connected inside the nozzle housing, and the inner wall of the support plate is fixedly connected to the outer wall of the funnel-shaped nozzle.
[0013] As a further description of the above technical solution:
[0014] The first connecting pipe has a groove inside, and the groove is rotatably connected to the outer wall of the rotating disk. The outer wall of the first connecting pipe is rotatably connected to the inside of the nozzle housing. A fan blade is fixedly connected to the bottom of the rotating disk.
[0015] As a further description of the above technical solution:
[0016] A second hollow column is fixedly connected inside the first connecting pipe, and a hollow block is fixedly connected to the outer wall of the second hollow column;
[0017] As a further description of the above technical solution:
[0018] A fixing post is provided inside the hollow block, and a spring is provided on the outer wall of the fixing post. One end of the spring is fixedly connected to the inside of the hollow block, and the other end of the spring is fixedly connected to a locking block.
[0019] As a further description of the above technical solution:
[0020] The top of the card block is provided with a first trapezoidal block, the bottom of the first trapezoidal block is fixedly connected to a connecting column, and the outer wall of the connecting column is slidably connected to a second trapezoidal block.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the liquid passes through the second connecting pipe and is sprayed out through the funnel-shaped nozzle, which increases the impact force and solves the problem that the water pressure of the nozzle in the prior art is too low, which reduces the quality of rinsing and improves the stability of the cavitation jet impactor.
[0023] 2. In this utility model, pressing the first connecting pipe causes the hollow column to move, which in turn moves the locking block. The movement of the locking block retracts the spring on the side wall, and the locking block moves against the bottom surface of the first trapezoidal block. When the locking block moves, it also moves the second trapezoidal block, achieving the effect of quickly disassembling and cleaning the nozzle housing. This solves the problem in the prior art where the use of threaded connections leads to thread rust, making the disassembly of the nozzle housing extremely difficult instead of a smooth process. This improves the convenience of the cavitation jet impactor. Attached Figure Description

[0031] 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.
[0032] Reference Figure 1 , Figure 3 and Figure 5 An embodiment of this utility model is provided: a cavitation jet impactor, including a water flow shell 2, which may be made of high-strength stainless steel. A first connecting pipe 3 is slidably connected to the top of the water flow shell 2. The first connecting pipe 3 is preferably made of aluminum alloy. A nozzle shell 1 is slidably connected to the top of the first connecting pipe 3. The nozzle shell 1 may be injection molded from engineering plastic. A spraying component is provided inside the nozzle shell 1.
[0033] The spraying assembly includes a rotating disk 5, which can be made of high-strength alloy steel. The outer wall of the rotating disk 5 is rotatably connected to the inside of the nozzle housing 1. A second connecting pipe 20 is fixedly connected inside the rotating disk 5, and a funnel-shaped nozzle 7 is fixedly connected to the top of the second connecting pipe 20. The funnel-shaped nozzle 7 can be made of ceramic, which has high hardness and wear resistance. A first hollow column 6 is fixedly connected inside the rotating disk 5, and an angled nozzle 9 is fixedly connected to one end of the first hollow column 6. The angled nozzle 9 can be made of stainless steel and surface hardened. A rotating assembly is installed inside the nozzle housing 1. The component includes a connecting shaft 18, which can be made of stainless steel. The outer wall of the connecting shaft 18 is rotatably connected to the inside of the nozzle housing 1. The other side of the connecting shaft 18 is rotatably connected to the inside of the first connecting pipe 3. A support plate 8 is fixedly connected inside the nozzle housing 1. The inner wall of the support plate 8 is fixedly connected to the outer wall of the funnel-shaped nozzle 7. A sliding groove 4 is opened inside the first connecting pipe 3. The sliding groove 4 is rotatably connected to the outer wall of the rotating disk 5. The outer wall of the first connecting pipe 3 is rotatably connected to the inside of the nozzle housing 1. A fan blade 19 is fixedly connected to the bottom of the rotating disk 5. The fan blade 19 can be made of engineering plastic and reinforced with glass fiber.
[0034] Specifically, when the jet injector is put into use, the water flow plays a crucial role as the driving source. When the water surges in, the fan blade 19 is the first to be impacted by the powerful flow, and under this force, it begins to rotate rapidly. The fan blade 19 is closely connected to the rotating disk 5, and the rotation of the fan blade 19 drives the rotating disk 5 to rotate as well. The rotating disk 5 rotates smoothly along a specific track, that is, inside the slide groove 4. As the rotating disk 5 rotates, the associated internal first hollow column 6 and the angled nozzle 9 are also driven, beginning a cyclical rotational motion, thus achieving the special spraying effect and function desired by the irregularly shaped nozzle. However, when the liquid flows inside the device, passing through the second connecting pipe 20 and flowing to the funnel-shaped nozzle 7, the funnel-shaped nozzle 7 plays a unique role due to its cleverly designed inclined surface. During the liquid's flow through the inner wall of the second connecting pipe 20, the presence of the inclined surface of the funnel-shaped nozzle 7 causes water bubbles in the liquid to collide upon contact with the inclined surface. This collision is not meaningless; it causes the bubbles to continuously enlarge. As the bubbles gradually enlarge, the pressure inside the liquid also increases accordingly, and this increased pressure directly leads to a stronger impact force. As a result, when the liquid is finally ejected from the nozzle, it possesses a more powerful impact force, enabling a more thorough and efficient cleaning of the target object's surface. This leads to better cleaning results and significantly improves the practicality and effectiveness of the jet cleaner in the cleaning field.
[0035] Reference Figure 2 and Figure 4 The first connecting pipe 3 is internally fixedly connected to a second hollow column 10, which may be made of aluminum alloy. The outer wall of the second hollow column 10 is fixedly connected to a hollow block 11, which may be made of engineering plastic. The hollow block 11 is internally provided with a fixing column 13. The outer wall of the fixing column 13 is provided with a spring 12, which may be made of high-quality carbon steel and rust-proof. One end of the spring 12 is fixedly connected to the inside of the hollow block 11, and the other end of the spring 12 is fixedly connected to a locking block 17. The top of the locking block 17 is provided with a first trapezoidal block 14, and the bottom of the first trapezoidal block 14 is fixedly connected to a connecting column 16, which may be made of stainless steel. The outer wall of the connecting column 16 is slidably connected to a second trapezoidal block 15.
[0036] Specifically, when operating the cavitation jet impactor, the first step is to precisely press the nozzle housing 1. When the nozzle housing 1 is subjected to external force, it will transmit the force and cause the first connecting pipe 3 connected to its bottom to move accordingly. The movement of the first connecting pipe 3 further causes the associated second hollow column 10 to move. Since the second hollow column 10 is tightly connected to the hollow block 11 on the side wall, the hollow block 11 will move synchronously with the movement of the second hollow column 10. During the movement of the hollow block 11, the spring 12 inside it will be pulled and deformed. While the spring 12 is contracting, it will also cause the fixed column 13 inside it to change position. The movement of the fixed column 13 will cause the locking block 17 on the side wall to move accordingly. At this time, the locking block 17 will press its side wall against the bottom of the first trapezoidal block 14. When the nozzle housing 1 is disassembled, the movement of the side wall of the locking block 17 will cause the second trapezoidal block 15 to slide. The second trapezoidal block 15 moves until its top is tightly pressed against the bottom of the first trapezoidal block 14. In this state, the first trapezoidal block 14 and the second trapezoidal block 15 can perfectly fit together to form a specific model structure, and the two sides can be seamlessly connected. In this way, the locking block 17 can slide out smoothly, and finally achieve the expected effect of quickly disassembling the nozzle housing 1, which greatly improves the convenience and efficiency of replacing or repairing the nozzle housing 1. At the same time, under the impact of the water channel, the locking block 17 will always be tightly pressed against the bottom surface of the first trapezoidal block 14, and there will always be a squeezing force.
[0037] Working Principle: When using the cavitation jet impactor, firstly, pressing the nozzle housing 1 causes the first connecting pipe 3 at the bottom to move under force. The movement of the first connecting pipe 3 moves the second hollow column 10, which in turn moves the hollow block 11 on the side wall. As the hollow block 11 moves, it causes the internal spring 12 to contract, which in turn moves the internal fixing column 13. The movement of the fixing column 13 moves the side wall locking block 17, causing the side wall to press against the bottom of the first trapezoidal block 14. During disassembly, the side wall of the locking block 17 also causes the second trapezoidal block 15 to slide, and then the second trapezoidal block 15 moves to press its top against the bottom of the first trapezoidal block 14. Finally, the first trapezoidal block 14 and the second trapezoidal block 15 are fitted together to form a model, with the two sides attached... After closing, the locking block 17 can be slid out, achieving the effect of quickly disassembling the nozzle housing 1. Then, when the jet injector is in use, the fan blade 19 is driven to rotate by the impact of the water flow, and the rotation of the fan blade 19 drives the rotating disk 5 to rotate as well. The rotation of the rotating disk 5 causes it to rotate inside the slide groove 4. Next, the rotation of the rotating disk 5 drives the first hollow column 6 and the angled nozzle 9 to rotate respectively. In addition, the funnel-shaped nozzle 7 is fixed inside the nozzle housing 1, and the funnel-shaped nozzle 7 is stably fixed inside the nozzle housing 1 by the support plate 8, achieving the effect of an irregular nozzle. However, when the liquid flows through the second connecting pipe 20 to the funnel-shaped nozzle 7, the design of the funnel-shaped nozzle 7 causes the water bubbles to collide with the inner wall of the second connecting pipe 20, resulting in enlarged water bubbles, increased pressure, and increased impact force, thus achieving a better cleaning effect.
[0038] 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.
