Description

Technical Field

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

[0002] High-pressure cleaning equipment is widely used in industrial cleaning, municipal sanitation, and large equipment maintenance due to its high efficiency in removing contaminants. However, traditional high-pressure cleaning equipment suffers from several technical challenges in actual operation, which limit the improvement of cleaning efficiency and ease of operation.

[0003] In the chemical dosing stage, existing equipment mostly relies on manual scooping or forced extraction by pumps. The former easily leads to chemical waste and measurement errors, while the latter requires additional power units, increasing energy consumption and posing a risk of pipeline leaks. Furthermore, chemicals are usually placed directly inside the equipment or in simple containers, lacking proper separation from the cleaning agent storage area. This design allows different types of cleaning agents to easily come into contact with each other, causing cross-contamination and affecting cleaning effectiveness. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-pressure cleaning device that solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A high-pressure cleaning device, comprising:

[0007] The base is equipped with a bracket and a push rod. A water pump is installed on the side of the base away from the push rod. A turbine is installed at the end of the water pump. An inlet pipe is provided on the turbine. The inlet pipe is connected to the bottom of the medicine box in the medicine tank through a medicine inlet pipe and a conduit. The negative pressure generated by the rotation of the turbine automatically draws the medicine in the medicine box into the inlet pipe.

[0008] The turbine is equipped with a liquid outlet connector at its output end, and a pressure relief port and a pressure gauge are sequentially arranged between the turbine and the liquid outlet connector.

[0009] The base is equipped with casters at its bottom.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the medicine box is equipped with a fixing seat, which is located on one side of the medicine box and stores several cleaning agents.

[0012] The beneficial effects of adopting the above-mentioned further solutions are:

[0013] By adding independent mounting bases inside the reagent tank, modular storage and management of cleaning agents are achieved. The lateral layout design of the mounting bases and reagent boxes makes full use of the internal space of the tank, avoiding the risk of cross-contamination caused by direct contact between the cleaning agents and the reagent boxes, and facilitating users to quickly access different types of cleaning agents (such as acidic rust removers and alkaline degreasers). In addition, the partitioned structure of the mounting bases effectively prevents the cleaning agents from tipping over due to shaking during equipment movement, improving the stability and safety of reagent storage.

[0014] Furthermore, the inlet tube is detachably sealed to the bottom of the medicine box, and the fixing seat is provided with a positioning groove that matches the shape of the cleaning agent.

[0015] The beneficial effects of adopting the above-mentioned further solutions are:

[0016] The detachable sealed connection design gives the inlet tube a dual advantage: First, users can quickly replace the medicine box by inserting and removing it, and switch the cleaning agent type without the need for tools, which significantly shortens the equipment debugging time; Second, the sealing structure uses a double-layer silicone sealing ring, which can maintain zero leakage under high pressure conditions, avoiding the wear and leakage problems caused by long-term use of traditional threaded connections.

[0017] Furthermore, the pulley is a universal wheel with a braking function.

[0018] The beneficial effects of adopting the above-mentioned further solutions are:

[0019] The introduction of braked swivel casters significantly enhances the equipment's mobility and operational stability. Their omnidirectional rotation allows the equipment to easily handle turning needs in confined spaces or complex terrain, while the braking mechanism, through its mechanical locking design, can fix the equipment's position during high-pressure injection, avoiding the risk of displacement due to reaction forces. Furthermore, the quick-release function of the braking system further simplifies the operation process, balancing ease of movement with operational safety.

[0020] Furthermore, the turbine is coaxially connected to the output shaft of the water pump via a flange, and a spiral guide groove is provided on the inner wall of the inlet pipe.

[0021] The beneficial effects of adopting the above-mentioned further solutions are:

[0022] The coaxial connection structure eliminates transmission errors through high-precision alignment, ensuring the synchronization of the turbine and water pump speeds, thereby improving energy transfer efficiency and system stability. The spiral guide channel optimizes the fluid path, creating a stable vortex during the cleaning agent intake process, achieving thorough mixing of the agent and water. This design not only shortens the mixing path but also reduces fluid resistance, thus increasing the outlet water pressure at the same power output and enhancing the equipment's cleaning capability.

[0023] Furthermore, the pressure gauge is connected in parallel to the pipeline between the pressure relief port and the turbine via a three-way connector, and the pressure relief port is equipped with a pressure regulating valve.

[0024] The beneficial effects of adopting the above-mentioned further solutions are:

[0025] The parallel pressure monitoring and regulation system establishes a dual safety protection mechanism: the pressure gauge design, independent of the main fluid path, avoids reading errors caused by fluid flow impact, providing users with accurate pressure feedback; while the pressure regulating valve at the pressure relief port, through automatic pressure sensing and rapid response functions, can promptly relieve pressure in the event of system overpressure, preventing damage to pipelines or seals. Furthermore, the manual adjustment knob supports flexible setting of pressure thresholds, adapting to the pressure requirements of different cleaning scenarios and improving the equipment's versatility.

[0026] Furthermore, the liquid outlet connector is a quick-change interface, and its input end is connected to the output end of the turbine through a pipe.

[0027] The beneficial effects of adopting the above-mentioned further solutions are:

[0028] The quick-change interface, with its snap-locking and double-seal design, enables rapid nozzle replacement and high-pressure sealing. Users can easily switch nozzle types with a simple operation, significantly improving work efficiency. The standardized interface design is compatible with mainstream high-pressure accessories on the market, expanding the equipment's application scenarios; while the internal multi-stage sealing structure ensures zero-leakage performance under high-pressure conditions, balancing ease of operation and reliability.

[0029] This utility model provides a high-pressure cleaning device. It has the following beneficial effects:

[0030] The spiral guide grooves on the inner wall of the inlet pipe, designed through fluid dynamics, create a spiral vortex within the pipe as the cleaning agent is drawn in. This vortex effect significantly increases the contact area between the cleaning agent and water, achieving uniform mixing at the molecular level and avoiding the sedimentation or stratification problems associated with traditional straight-pipe inlets. The spiral structure also reduces fluid resistance and energy consumption.

[0031] The pressure relief port and pressure gauge are connected in parallel to the turbine output pipeline via a tee fitting, forming a pressure feedback closed-loop system. The pressure regulating valve can adjust its opening in real time according to the pipeline pressure, and automatically releases pressure when the system pressure exceeds the safety threshold to prevent pipeline rupture or equipment damage. The pressure gauge is designed independently of the main hydraulic circuit to avoid reading fluctuations caused by fluid flow impact, ensuring that users obtain real-time pressure data.

[0032] The turbine is coaxially connected to the water pump output shaft via a flange, using centrifugal force to repressurize the mixture. The turbine blades feature an involute curved surface design, forming a stable liquid film during high-speed rotation and reducing pressure fluctuations caused by turbulence.

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.

[0042] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows: Example 1

[0043] A high-pressure cleaning device, comprising:

[0044] The base 1 is equipped with a bracket 105 and a push rod 3. A water pump 102 is installed on the side of the base 1 away from the push rod 3. A turbine 101 is installed at the end of the water pump 102. An inlet pipe 109 is provided on the turbine 101. The inlet pipe 109 is connected to the bottom of the medicine box 202 in the medicine tank 2 through a medicine inlet pipe 108 and a conduit. The negative pressure generated by the rotation of the turbine 101 automatically draws the medicine in the medicine box 202 into the inlet pipe 109.

[0045] A liquid outlet connector 106 is installed at the output end of the turbine 101, and a pressure relief port 104 and a pressure gauge 107 are sequentially arranged between the turbine 101 and the liquid outlet connector 106.

[0046] A pulley 103 is installed at the bottom of the base 1. The pulley 103 is a universal wheel with a brake function. The introduction of the braked universal wheel significantly enhances the mobility and operational stability of the equipment. Its omnidirectional rotation characteristic allows the equipment to easily cope with the turning needs of narrow spaces or complex terrains, while the braking mechanism, through a mechanical locking design, can fix the position of the equipment during high-pressure injection, avoiding the risk of displacement caused by reaction force. In addition, the quick unlocking function of the braking system further simplifies the operation process, taking into account both mobility and safety. Example 2

[0047] To optimize the convenience of reagent storage and replacement, and to improve the equipment's adaptability to various cleaning tasks, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0048] The reagent box 2 is equipped with a mounting base 201, located on one side of the reagent container 202, which stores several cleaning agents 203. By adding an independent mounting base 201 inside the reagent box 2, modular storage and management of the cleaning agents 203 are achieved. The lateral layout design of the mounting base 201 and the reagent container 202 makes full use of the internal space of the box, avoiding the risk of cross-contamination caused by direct contact between the cleaning agents 203 and the reagent container 202, and facilitating users to quickly access different types of cleaning agents 203 (such as acidic rust removers, alkaline degreasers, etc.). Furthermore, the partitioned structure of the mounting base 201 effectively prevents the cleaning agents 203 from tipping over due to shaking during equipment movement, improving the stability and safety of reagent storage. The inlet tube 108 and the bottom of the medicine box 202 are connected by a detachable sealed connection, and the fixing seat 201 is provided with a positioning groove that matches the shape of the cleaning agent 203. The detachable sealed connection design gives the inlet tube 108 a dual advantage: First, users can quickly replace the medicine box 202 by inserting and removing it, and can switch the type of cleaning agent 203 without the need for tools, which significantly shortens the equipment debugging time; Second, the sealing structure adopts a double-layer sealing ring made of silicone material, which can maintain zero leakage under high pressure conditions, avoiding the wear and leakage problems caused by long-term use of traditional threaded connections. Example 3

[0049] To improve the power transmission efficiency and cleaning pressure stability of the equipment, and to enhance system safety and operational versatility, for example, such as Figures 1 to 4 As shown, this utility model also includes:

[0050] The turbine 101 is coaxially connected to the output shaft of the water pump 102 via a flange. A spiral guide groove is provided on the inner wall of the inlet pipe 109. The coaxial connection structure, through a high-precision alignment design, eliminates transmission errors, ensuring the synchronous rotational speeds of the turbine 101 and the water pump 102, thereby improving energy transfer efficiency and system stability. The spiral guide groove optimizes the fluid path, forming a stable vortex during the intake of the cleaning agent 203, achieving thorough mixing of the agent and water. This design not only shortens the mixing path but also reduces fluid resistance, thereby increasing the outlet water pressure at the same power and enhancing the cleaning capability of the equipment. Pressure gauge 107 is connected in parallel to the pipeline between pressure relief port 104 and turbine 101 via a three-way connector. Pressure relief port 104 is equipped with a pressure regulating valve. The parallel pressure monitoring and regulation system constructs a dual safety protection mechanism: the pressure gauge 107, designed independently of the main liquid circuit, avoids reading errors caused by liquid flow impact, providing users with accurate pressure feedback; while the pressure regulating valve of pressure relief port 104, through automatic pressure sensing and rapid response functions, can promptly relieve pressure when the system is over-pressurized, preventing damage to pipelines or seals. In addition, the manual adjustment knob supports flexible setting of pressure thresholds to adapt to the pressure requirements of different cleaning scenarios, improving the equipment's versatility. The liquid outlet connector 106 is a quick-change interface, whose input end is connected to the output end of turbine 101 via a pipeline. The quick-change interface, through snap-locking and double-sealing design, enables rapid nozzle replacement and high-pressure sealing. Users can easily switch nozzle types with simple operations, significantly improving work efficiency. The standardized interface design is compatible with mainstream high-voltage components on the market, expanding the application scenarios of the equipment; while the internal multi-stage sealing structure ensures zero leakage performance under high-voltage conditions, taking into account both ease of operation and reliability.

[0051] Working principle:

[0052] The user inserts the medicine box 202 into the fixing base 201 of the medicine tank 2, using the positioning groove on the fixing base 201 to ensure the cleaning agent 203 container is stably placed. Then, the inlet pipe 108 is detachably and sealed to the bottom of the medicine box 202, completing the construction of the medicine delivery channel. At this time, the braking function of the pulley 103 keeps the equipment stably parked.

[0053] After the water pump 102 is started, the output shaft of the water pump 102 drives the turbine 101 to rotate at high speed through the flange. The negative pressure effect generated inside the turbine 101 creates a suction force in the inlet pipe 109, and the cleaning agent 203 in the agent tank 2 is automatically drawn into the inlet pipe 109 through the inlet pipe 108. The spiral guide groove design on the inner wall of the inlet pipe 109 plays a key role in this process: its spiral structure causes the water flow to generate a vortex effect, so that the cleaning agent 203 and water are fully mixed to form a uniform cleaning solution.

[0054] After the mixed cleaning fluid enters the turbine 101, it is further pressurized under centrifugal force. The pressurized liquid then passes through the pressure relief port 104 and the pressure gauge 107 in sequence. The pressure regulating valve equipped with the pressure relief port 104 can adjust the system pressure in real time, and automatically release pressure when the pressure exceeds the set value to prevent overpressure in the pipeline. The pressure gauge 107, connected in parallel in the pipeline, continuously displays the current working pressure through a tee connector, providing users with intuitive pressure data for reference.

[0055] The pressure-stable cleaning fluid enters the outlet connector 106 through the output end of the turbine 101. This connector features a quick-change design, allowing users to quickly replace nozzles of different specifications according to the cleaning scenario. Finally, the high-pressure cleaning fluid is ejected from the nozzle at high speed, using the impact force of the water flow to complete the cleaning operation on the target surface.

[0056] After the water pump 102 is turned off, the turbine 101 stops rotating, and the system pressure gradually returns to zero. The user can unseal the inlet pipe 108, remove the medicine box 202 for replenishment or replacement, and use the pulley 103 to move the equipment to the storage position, and use the brake function to fix the equipment to prevent slippage.

[0057] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
