Description

Technical Field

[0001] This utility model belongs to the technical field of high-pressure water cleaning equipment, specifically relating to a high-pressure cleaning device. Background Technology

[0002] High-pressure cleaning devices use a power unit to drive a high-pressure pump to generate high-pressure water, which is then sprayed onto the surface of an object through overflow guns (commonly known as high-pressure water guns or overflow guns). This process removes and rinses away dirt, achieving the purpose of cleaning the object's surface. Existing high-pressure cleaning devices mostly use mechanical control systems, which have many components, resulting in high manufacturing costs and short service life. Furthermore, when supplying high-pressure water to two overflow guns simultaneously, the opening and closing of one gun can affect the normal operation of the other, causing inconvenience.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 1 As shown, a high-pressure cleaning device includes a high-pressure pump 1, a three-way valve 2, two drain guns 3, and two pneumatically controlled diverter valves 4. The high-pressure pump is connected to an inlet pipe. The inlet end of the three-way valve is connected to the outlet end of the high-pressure pump. The two outlet ends of the three-way valve are respectively connected to the inlet ends of the two drain guns via high-pressure water supply lines 16. Each drain gun is equipped with a control circuit board 5, which is connected to a signal transmitting module and a push-button switch 6 for controlling the signal transmitting module. A pneumatically controlled diverter valve is installed on the high-pressure water supply line, and a signal receiving module that cooperates with the corresponding signal transmitting module is connected to the pneumatically controlled diverter valve. One outlet of the pneumatically controlled diverter valve is connected to the drain gun via the high-pressure water supply line, and the other outlet is sealed with a threaded plug (see reference). Figure 1 As shown in the figure, the pneumatically controlled diverter valve also has an overflow port (not shown in the figure). The high-pressure pump continuously supplies high-pressure water to two high-pressure water supply lines through a three-way valve. The signal transmission control is achieved through the push-button switch on each discharge gun, and the signal receiving module on the corresponding pneumatically controlled diverter valve receives the signal, shuts off the water supply to the discharge gun, and discharges the high-pressure water from the overflow port of the pneumatically controlled diverter valve. This realizes the remote control of the high-pressure water opening and closing of the discharge gun, which not only simplifies the equipment structure and reduces the equipment manufacturing and maintenance costs, but also ensures that the two guns do not interfere with each other during operation, making it more convenient to use. The high-pressure pump and pneumatic diverter valve in this embodiment are both proprietary products of the applicant and are publicly available for sale. Their models are SN-HH-3000-45-DS and SN-QKF-02, respectively. The signal transmitting module and signal receiving module are both purchased components, manufactured by Dech Wireless Application Technology (Shanghai) Co., Ltd. Their models are DCH-2021-12--V01 and DCH-2024-12-V01, respectively. All of the above products are existing technology products, and their specific structures will not be described in detail here.

[0030] like Figure 2 and Figure 4 As shown, the venting gun includes a gun base 301, a venting pipe 302, an electrical control compartment 303, and a trigger assembly 304 mounted on the gun base. The outlet end of the venting pipe is equipped with a nozzle 3021, and its inlet end is connected to a high-pressure water supply pipeline. The control circuit board is located in the electrical control compartment. The trigger assembly is connected to the button drive. The button is pressed by using the trigger assembly. When the button is pressed, the signal transmitting module sends a water supply signal. After receiving the corresponding signal, the signal receiving module controls the pneumatic diversion valve to deliver high-pressure water to the high-pressure water supply pipeline. The high-pressure water enters from the inlet end of the venting pipe and is sprayed out from the nozzle for cleaning.

[0031] Combination Figures 2 to 5As shown, a cover 7 is detachably installed on one side of the electrical control compartment. A power supply 8 is located inside the compartment and is electrically connected to the circuit board. The power supply uses a battery to provide power to the circuit board. A slide 9 is located inside the compartment and is slidably connected to a slide rail 10 on the inner wall of the compartment. The control circuit board and power supply are mounted on the slide, facilitating maintenance of the control circuit board and replacement of the power supply. The cover is made of a transparent material, such as acrylic, allowing for easy observation of the interior. The cover is detachably secured to the outside of the electrical control compartment using screws or fastening bolts.

[0032] The gun holder includes a base 3011 and a top plate 3012 mounted on the top of the base. The upper end face of the base and the lower end face of the top plate are respectively provided with semi-circular positioning grooves. The two semi-circular positioning grooves form a clamping groove 3013 for accommodating the drain pipe. The top plate and the base are connected by screw assembly. A fastening screw 14 is threaded on the top plate. The end of the fastening screw abuts against the drain pipe to effectively fix the drain pipe and prevent it from shaking during use.

[0033] Combination Figures 2 to 6 As shown, the trigger assembly includes a first positioning shaft 3041 and a second positioning shaft 3042 located inside the gun base. A trigger 3043 is rotatably connected to the first positioning shaft, and a stop block 3044 is rotatably connected to the second positioning shaft. A positioning buckle 3045 connects the first trigger and the stop block. The two ends of the positioning buckle are rotatably connected to the trigger and the stop block respectively via pins 3046. The end of the stop block near the positioning buckle abuts against a push-button switch located inside the gun base. When the lower part of the trigger is pulled, the upper part of the trigger deflects away from the second positioning shaft, causing the stop block to move clockwise along the second positioning shaft, pressing the push-button switch upwards. The signal transmitting module sends a water supply signal to supply water. Conversely, when the lower part of the trigger returns to its original position in the opposite direction, the upper part of the trigger deflects towards the second positioning shaft, causing the stop block to move counterclockwise along the second positioning shaft, releasing the push-button switch. The signal transmitting module stops sending signals, disconnecting the water supply, thus stopping the water flow from the drain gun.

[0034] A limit post 3047 is provided on one side of the trigger to limit the travel of the trigger during pulling, preventing damage caused by excessive button pressing. A stop latch 3048 is rotatably connected to the other side, and a torsion spring 3049 connected to the trigger is located inside the stop latch. Rotating the stop latch counterclockwise causes it to abut against the gun mount (e.g., Figure 2 The stop lock (perpendicular to the wrench) restricts trigger movement, preventing accidental trigger contact and improving safety. Conversely, rotating the stop lock clockwise to make it parallel to the wrench allows normal triggering for water cleaning. The torsion spring design facilitates automatic trigger reset after release, making it more convenient to use.

[0035] like Figure 2 and Figure 4 As shown, a support rod 11 is connected to the rear end of the gun base, and a top shoulder 12 is connected to the end of the support rod, facilitating stable control when the user holds the discharge gun. A fixing plate 13 is connected to the end of the support rod away from the top shoulder. The fixing plate is detachably connected to the gun base. In this embodiment, the fixing plate and the gun base are connected by screws for easy assembly and disassembly. Both ends of the support rod are connected to the fixing plate and the top shoulder by threads.

[0036] The method of using this utility model is as follows:

[0037] like Figures 1 to 7 As shown, during high-pressure cleaning, the high-pressure pump 1 delivers high-pressure water to two high-pressure water supply pipes 16 through the tee 2. Two operators each hold a drain gun 3, release the safety protection function of the stop buckle 3048, pull the trigger 3043, the trigger 3043 deflects counterclockwise, and drives the contact block 3044 to move clockwise along the second positioning axis 3042. Pressing the button switch 6 upwards, the signal transmitting module sends a signal, and after the signal receiving module receives the corresponding signal, the pneumatic diversion valve 4 supplies high-pressure water to the drain gun. The operator can then align the nozzle 3021 of the drain pipe 302 with the object to be cleaned to perform high-pressure cleaning. After cleaning, release the trigger 3043. The trigger 3043 will automatically reset (rotate clockwise) under the action of the torsion spring 3049, causing the contact block 3044 to move counterclockwise along the second positioning axis 3042, releasing the pressure on the button switch 6. The signal transmission module will stop sending signals, and the pneumatic diversion valve 4 will stop supplying high-pressure water to the discharge gun 3. The high-pressure water will be discharged from the overflow port of the pneumatic diversion valve 4.

[0038] 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. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
