Description

Technical Field

[0001] This utility model belongs to the technical field of high-pressure cleaners, specifically a water metering mechanism for a high-pressure cleaner. Background Technology

[0002] A high-pressure washer is a device that uses a power unit to drive a high-pressure plunger pump to generate a high-pressure water jet, thereby cleaning the surface of an object. Through the powerful water jet, it efficiently peels off and washes away dirt, achieving the cleaning purpose. Because high-pressure cleaning does not require chemical cleaning agents and relies solely on the impact force of water, it has become one of the globally recognized scientific, economical, and environmentally friendly cleaning methods. This technology is widely used in industrial equipment, building surfaces, and transportation vehicles, protecting the environment while significantly improving cleaning efficiency, making it an important tool in modern cleaning technology.

[0003] Currently, various methods have been proposed for water metering mechanisms in high-pressure cleaners. For example, patent application CN219519770U discloses a water metering mechanism for high-pressure cleaners. In this method, the level probe of a submersible level transmitter is first inserted into the water storage tank of the high-pressure cleaner. Then, the mounting plate is inserted into the mounting base. The drive block is then rotated, causing the lead screw to rotate and move the positioning block upwards along the mounting groove until it enters the groove and presses the mounting plate firmly, thus completing the installation of the submersible level transmitter. However, each time the mounting plate is installed, the drive block needs to be rotated to press the mounting plate firmly. With frequent and prolonged pressing, the surface of the mounting plate is prone to deformation. A deformed mounting plate cannot firmly fix the submersible level transmitter, affecting the normal operation and metering accuracy of the metering mechanism.

[0004] Therefore, this utility model provides a water metering mechanism for a high-pressure cleaner. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The water metering mechanism of the high-pressure cleaner of this utility model includes a water storage tank. A fixed sleeve is fixedly connected to the upper end of the water storage tank. An immersion-type liquid level transmitter is slidably connected inside the fixed sleeve. A liquid level probe is fixedly connected to one end of the immersion-type liquid level transmitter. A slot is opened at the other end of the immersion-type liquid level transmitter. A pin is slidably connected to the fixed sleeve. The pin slides in the slot. A pull plate is fixedly connected to the end of the pin away from the fixed sleeve. A reset mechanism for resetting the pin is installed on the pull plate. A cleaning mechanism for cleaning the inner wall of the water storage tank is installed on the water storage tank. A water outlet pipe is connected to the side wall of the water storage tank.

[0007] Preferably, the reset mechanism includes a spring, one end of which is fixedly mounted on the side wall of the pull plate, and the other end of which is fixedly mounted on the side wall of the fixing sleeve.

[0008] Preferably, the cleaning mechanism includes a U-shaped rod, a nut, and a cleaning ring. One end of the U-shaped rod is fixedly installed on the upper end of the cleaning ring, and the other end of the U-shaped rod is fixedly installed on the upper end of the nut. The cleaning ring slides inside the water storage tank. A guide mechanism for guiding the nut is installed on the water storage tank. A fixing plate is fixedly installed on the side wall of the water storage tank, and a moving mechanism for moving the nut is installed on the fixing plate.

[0009] Preferably, the guiding mechanism includes a slider, the side wall of the water storage tank is provided with a groove, one end of the slider is fixedly installed on the side wall of the nut, and the other end of the slider slides in the groove.

[0010] Preferably, a solenoid valve is installed inside the water outlet pipe.

[0011] Preferably, the moving mechanism includes a gear and a screw, a rectangular plate is fixedly installed on the side wall of the water storage tank, the nut is threaded onto the screw, the fixing plate is fixedly installed on the side wall of the water storage tank, one end of the screw is fixedly installed on the upper end of the gear, the other end of the screw is rotatably installed on the lower end of the rectangular plate, and a rotating mechanism for rotating the gear is installed on the pin.

[0012] Preferably, the rotating mechanism includes a connecting rod and a rack. One end of the connecting rod is fixedly mounted on a pin, and the other end of the connecting rod is fixedly mounted on the upper end of the rack. The rack slides on the surface of the fixed plate and meshes with a gear.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. The water metering mechanism for a high-pressure washer described in this utility model involves pulling a pull plate outward, causing the pull plate to move a pin and compressing a spring. At this point, one end of a submersible level transmitter is inserted into a fixing sleeve. Releasing the pull plate allows the pin to automatically move into a slot under the action of the spring, thus completing the fixed installation of the submersible level transmitter. This design avoids direct pressure from parts on the submersible level transmitter, reducing the risk of deformation and extending the equipment's service life. Simultaneously, it significantly reduces manual operation steps and improves installation efficiency.

[0015] 2. The water metering mechanism of the high-pressure washer described in this utility model uses the reciprocating movement of the pin to cause the connecting rod to drive the rack to reciprocate, thereby causing the gear to rotate alternately in both directions. At the same time, the screw rotates in both directions, which in turn causes the nut to move up and down. This causes the nut to drive the U-shaped rod to move the cleaning ring up and down, so that the cleaning ring can clean the inner wall of the water tank, evenly covering the entire inner wall area, effectively removing scale and dirt, and avoiding cleaning dead corners.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 4As shown in the embodiment of this utility model, a water metering mechanism for a high-pressure washer includes a water storage tank 1. A fixing sleeve 11 is fixedly connected to the upper end of the water storage tank 1. An immersion-type liquid level transmitter 16 is slidably connected inside the fixing sleeve 11. A liquid level probe 17 is fixedly connected to one end of the immersion-type liquid level transmitter 16, and a slot 18 is opened at the other end of the immersion-type liquid level transmitter 16. A pin 4 is slidably connected to the fixing sleeve 11 and slides inside the slot 18. A pull plate 3 is fixedly connected to the end of the pin 4 away from the fixing sleeve 11. A reset mechanism for resetting the pin 4 is installed on the pull plate 3. A cleaning mechanism for cleaning the inner wall of the water storage tank 1 is installed on the water storage tank 1. A water outlet pipe 2 is connected to the side wall of the water storage tank 1. During operation, pull the pull plate 3 outward, and the pull plate 3 will drive the pin 4 to move outward. At this time, the spring 5 is compressed, and one end of the submersible level transmitter 16 is inserted into the fixing sleeve 11. When the submersible level transmitter 16 contacts the side wall of the fixing sleeve 11, the pull plate 3 is released. Under the action of the compressed spring 5, the spring 5 instantly resets, so that the pin 4 automatically moves into the slot 18, thereby completing the fixed installation of the submersible level transmitter 16.

[0025] like Figure 1 and Figure 3 As shown, the reset mechanism includes a spring 5, one end of which is fixedly mounted on the side wall of the pull plate 3, and the other end of which is fixedly mounted on the side wall of the fixing sleeve 11. During operation, the spring 5 deforms under stress. When the pull plate 3 is released, the compressed spring 5 instantly resets, causing the pin 4 to automatically move into the slot 18, thus completing the fixed installation of the submersible level transmitter 16. With this structure, the entire installation process requires no complex operations, greatly simplifying the steps and improving efficiency.

[0026] like Figure 1 Figure 2 As shown, the cleaning mechanism includes a U-shaped rod 10, a nut 13, and a cleaning ring 15. One end of the U-shaped rod 10 is fixedly installed on the upper end of the cleaning ring 15, and the other end is fixedly installed on the upper end of the nut 13. The cleaning ring 15 slides within the water storage tank 1. A guide mechanism for guiding the nut 13 is installed on the water storage tank 1. A fixing plate 7 is fixedly installed on the side wall of the water storage tank 1, and a moving mechanism for moving the nut 13 is installed on the fixing plate 7. During operation, the alternating forward and reverse rotation of the screw 14 causes the nut 13 to move up and down, which in turn causes the nut 13 to drive the U-shaped rod 10 to move up and down. The U-shaped rod 10 then drives the cleaning ring 15 to move up and down within the water storage tank 1, thereby cleaning the inner wall of the water storage tank 1. Through this structure, the cleaning ring moves up and down within the inner wall, ensuring a wide and uniform cleaning coverage area, effectively removing scale and dirt from the water storage tank, and avoiding cleaning blind spots. Simultaneously, it reduces corrosion and clogging, thereby extending the service life of the water storage tank and related equipment.

[0027] like Figure 1 and Figure 4 As shown, the guiding mechanism includes a slider 19, and a groove 20 is provided on the side wall of the water tank 1. One end of the slider 19 is fixedly installed on the side wall of the nut 13, and the other end of the slider 19 slides within the groove 20. Through this structure, the side wall of the groove 20 limits the slider 19, ensuring that the nut 13 can only slide along the surface of the groove 20, preventing the nut 13 from shifting due to the rotation of the screw 14. This allows the cleaning ring 15 to slide along a preset path within the water tank 1, preventing poor cleaning performance.

[0028] like Figure 1 As shown, a solenoid valve is installed inside the water outlet pipe 2. Through this structure, the solenoid valve can achieve precise opening and closing control of the water flow, effectively adjusting the water volume to meet different cleaning needs.

[0029] like Figure 1 and Figure 2 As shown, the moving mechanism includes a gear 9 and a screw 14. A rectangular plate 12 is fixedly installed on the side wall of the water tank 1. The nut 13 is threaded onto the screw 14. The fixing plate 7 is fixedly installed on the side wall of the water tank 1. One end of the screw 14 is fixedly installed on the upper end of the gear 9, and the other end of the screw 14 is rotatably installed on the lower end of the rectangular plate 12. A rotating mechanism for rotating the gear 9 is installed on the pin 4. During operation, because the rack 8 meshes with the gear 9, the rotation direction of the gear 9 changes, that is, the gear 9 rotates alternately in both directions. This causes the gear 9 to drive the screw 14 to rotate alternately in both directions, thereby causing the nut 13 to drive the cleaning ring 15 to move up and down inside the water tank 1 via the U-shaped rod 10. Through the above structure, the alternating rotation of the gear 9 can flexibly change the rotation direction of the screw 14, ensuring that the cleaning ring covers the entire height of the inner wall of the water tank.

[0030] like Figure 1 As shown, the rotating mechanism includes a connecting rod 6 and a rack 8. One end of the connecting rod 6 is fixedly mounted on a pin 4, and the other end is fixedly mounted on the upper end of the rack 8. The rack 8 slides on the upper surface of the fixed plate 7 and meshes with a gear 9. During operation, the movement of the pin 4 also causes the connecting rod 6 to move synchronously, thereby causing the connecting rod 6 to drive the rack 8 to slide back and forth on the upper surface of the fixed plate 7. With the above structure, a single movement of the pin 4 can drive the entire transmission chain, simplifying the operation steps and improving the operating efficiency of the equipment.

[0031] Working principle: Pull the pull plate 3 outward, and the pull plate 3 will drive the pin 4 to move outward. At this time, the spring 5 will be compressed, and one end of the submersible level transmitter 16 will be inserted into the fixing sleeve 11. When the submersible level transmitter 16 contacts the side wall of the fixing sleeve 11, the pull plate 3 will be released. Under the action of the compressed spring 5, the spring 5 will instantly return to its original position, so that the pin 4 will automatically move into the slot 18, thereby completing the fixed installation of the submersible level transmitter 16.

[0032] At the same time, the pin 4 drives the rack 8 to move left and right through the connecting rod 6. The rack 8 meshes with the gear 9, so the rotation direction of the gear 9 will change, that is, the gear 9 rotates alternately in the forward and reverse directions. This causes the gear 9 to drive the screw 14 to rotate alternately in the forward and reverse directions, so that the nut 13 drives the cleaning ring 15 to move up and down inside the water tank 1 through the U-shaped rod 10. In this way, the cleaning ring 15 can clean the inner wall of the water tank 1.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
