Description

Technical Field

[0001] This utility model belongs to the technical field of high-pressure cleaning equipment, and in particular relates to a high-pressure cleaning unit that is easy to adjust. Background Technology

[0002] In fields such as industrial equipment cleaning, municipal sanitation operations, and building exterior wall cleaning, high-pressure cleaning units serve as core equipment, with their operational efficiency and flexibility directly impacting cleaning effectiveness and labor costs. The nozzle, as a key component at the execution end, requires frequent adjustments to the spray height, angle, and coverage area based on the height of the object being cleaned, surface curvature, and type of stains. However, traditional high-pressure cleaning units generally suffer from limited nozzle adjustment mechanisms, cumbersome operation, and poor adaptability, making it difficult to meet the high-efficiency cleaning needs of complex scenarios.

[0003] In existing technologies, nozzle height adjustment mostly relies on fixed brackets or telescopic rods, requiring bolt tightening or clip locking. Each adjustment necessitates stopping the machine and using tools, taking several minutes per adjustment. Furthermore, the height positioning accuracy is low, and continuous stepless adjustment is not possible. Angle adjustment structures often employ rigid hinge designs, limiting the adjustment angle range and lacking locking mechanisms. During high-pressure spraying, angle deviations due to vibration can lead to repeated or missed cleaning areas. When cleaning large-area flat or curved objects, traditional nozzles require manual back-and-forth oscillation, which is not only labor-intensive but also results in insufficient rinsing coverage and the creation of cleaning blind spots.

[0004] For scenarios requiring precise operation, existing units struggle to quickly disassemble the nozzles for handheld operation. The nozzles and piping are often connected by threads or rigidly fixed, requiring power off, pressure release, and specialized tools for disassembly—a time-consuming and labor-intensive process. Frequent disassembly can also cause wear on the interfaces, leading to potential leaks. Furthermore, traditional units generally lack nozzle rotation functionality or only allow manual unidirectional rotation, failing to achieve automatic reciprocating rotation, resulting in a limited cleaning path and low efficiency.

[0005] To address these issues, we provide an easily adjustable high-pressure cleaning unit. Utility Model Content

[0006] The purpose of this invention is to provide a high-pressure cleaning unit that is easy to adjust. By combining the adjustment component and the quick-release component, the problem of inconvenience in using existing high-pressure cleaning units is solved.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to an easily adjustable high-pressure cleaning unit, comprising a base plate, a water supply assembly fixedly connected to the top of the base plate, an adjustment assembly fixedly connected to one side of the water supply assembly, a quick-release assembly fixedly connected to the top of the adjustment assembly, a nozzle threadedly connected to the top of the quick-release assembly, and the water inlet of the nozzle communicating with the water supply assembly via a hose. The adjustment assembly includes a motor fixedly connected to the base plate, a lead screw fixedly connected to the output shaft of the motor, a threaded tube threadedly connected to the top of the lead screw, a mounting bracket fixedly connected to the top of the threaded tube, a mounting plate movably connected to the inner cavity of the mounting bracket via a pin, a hydraulic push rod movably connected between the mounting plate and the mounting bracket via a pin, a second motor fixedly connected to the bottom of the mounting plate, a reciprocating component fixedly connected to the output shaft of the second motor, and a threaded sleeve fixedly connected to the top of the reciprocating component via a bearing. A screw is threadedly connected to the inner cavity of the threaded sleeve, and the top of the screw is fixedly connected to the nozzle.

[0009] The present invention is further configured such that casters are fixedly connected to the four corners of the bottom of the base plate, and a brake pad is provided on one side of the caster. The design of the casters and brake pads allows the unit to move flexibly and be positioned stably, adapting to the terrain changes of different work sites and improving the mobility of the equipment.

[0010] The present invention is further configured such that the water supply component includes a water tank, a high-pressure water pump is connected to one side of the top of the water tank via a pipe, the outlet pipe of the high-pressure water pump is connected to a flexible hose, an inlet pipe is connected to the other side of the top of the water tank, a cap is threadedly connected to the top of the inlet pipe, and push handles are fixedly connected to both the front and rear ends of the other side of the water tank. The water supply component integrates the water tank, the high-pressure water pump and the push handle to form an independent water supply system. The push handle facilitates manual movement of the unit, and the cap design of the inlet pipe prevents debris from entering and ensures clean water supply.

[0011] The present invention is further configured such that limiting tubes are fixedly connected to both the front and rear ends of the bottom of the mounting bracket, and limiting rods are threadedly connected to the inner cavity of the limiting tubes. The bottom of the limiting rods is fixedly connected to the top of the base plate. The limiting tubes and the limiting rods constitute a guiding mechanism to limit the radial displacement of the spiral tube during lifting and lowering, enhance the structural stability during the height adjustment process, and avoid shaking.

[0012] The present invention is further configured such that the reciprocating component includes a drive disk fixedly connected to the second motor, and sector teeth are fixedly connected to both the outer and inner sides of the inner cavity of the drive disk. A follower gear meshes with the inner cavity of the sector teeth, and a transmission shaft is fixedly connected to the top of the follower gear. The surface of the transmission shaft is fixedly connected to the top of the mounting plate through a bearing seat. The reciprocating component adopts a sector tooth and follower gear meshing structure to convert the unidirectional rotation of the motor into the reciprocating oscillation of the transmission shaft, thereby realizing the automatic left and right rotation of the nozzle and expanding the cleaning coverage area.

[0013] The present invention is further configured such that a protective cover is fixedly connected to the top of the mounting plate by bolts, the top of the protective cover has an opening for the transmission shaft, a handle is fixedly connected to one end of the transmission shaft located at the top of the protective cover, and rotating rods are fixedly connected to both sides of the threaded sleeve surface. The protective cover covers the reciprocating transmission structure to prevent high-pressure water and dust from entering the gear meshing area, extend the service life of mechanical parts, and improve operational reliability.

[0014] The present invention is further provided that the top of the nozzle is fixedly connected to a handle, and the surface of the handle is covered with a rubber sleeve. The nozzle handle and the rubber sleeve are designed in accordance with ergonomics, which reduces hand fatigue when using the hand, and the rubber material enhances the grip friction and prevents slippage.

[0015] The present invention is further configured such that a connecting seat is fixedly connected to the bottom of the second motor, and the top of the connecting seat is fixedly connected to the bottom of the mounting plate. The connecting seat fixes the second motor, ensuring that the motor position is stable during power transmission, reducing the impact of vibration on adjustment accuracy, and improving the durability of the mechanical system.

[0016] The present invention has the following beneficial effects.

[0017] 1. This utility model constructs a three-degree-of-freedom adjustment system for height, angle, and rotation, significantly improving the accuracy and efficiency of cleaning operations. The first motor drives the lead screw and nut mechanism, enabling the screw tube to drive the mounting bracket to achieve stepless lifting and lowering of the nozzle height. It can quickly position the nozzle to the target height without stopping the machine or using tools. The hydraulic push rod links the mounting plate to swing around the pin shaft, which can flexibly adjust the nozzle spray angle within a large angle range. The hydraulic locking function maintains the angle stability, solving the problem of easy vibration and displacement of traditional rigid structures. The second motor drives the reciprocating component, which drives the nozzle to automatically rotate left and right through the gear meshing principle. It can cover a large cleaning area without manual swinging, avoiding cleaning blind spots. It is especially suitable for efficient rinsing of curved or complex surface structures, and the efficiency is greatly improved compared with the traditional manual adjustment method.

[0018] 2. This utility model's quick-release assembly adopts a bearing-connected threaded sleeve and screw design, allowing for quick assembly and disassembly of the nozzle and unit with a simple rotation. For delicate operations, there is no need to shut down the system or use tools; the nozzle can be removed by hand by rotating the screw. The top handle allows for handheld operation, and the rubber sleeve design enhances grip comfort and anti-slip properties. In the installed state, the threaded sleeve rotates synchronously with the reciprocating parts, ensuring stable water circuit connection when the nozzle rotates. After disassembly, the hose remains connected, and the spray direction can be freely controlled in handheld mode. It combines the efficiency of mechanized operations with the precision of manual operation, solving the problems of traditional units having limited functionality and cumbersome switching, and meeting the needs of diverse cleaning scenarios.

[0027] Example 1

[0028] Please see Figure 1-5This utility model relates to an easily adjustable high-pressure cleaning unit, comprising a base plate 1, a water supply assembly 2 fixedly connected to the top of the base plate 1, an adjustment assembly 3 fixedly connected to one side of the water supply assembly 2, a quick-release assembly 4 fixedly connected to the top of the adjustment assembly 3, a nozzle 5 threadedly connected to the top of the quick-release assembly 4, and a water inlet of the nozzle 5 connected to the water supply assembly 2 via a hose. The adjustment assembly 3 includes a motor 31 fixedly connected to the base plate 1, a lead screw 32 fixedly connected to the output shaft of the motor 31, and a screw tube 3 threadedly connected to the top of the lead screw 32. 3.

[0031] Please see Figure 1-5Based on Embodiment 1, casters are fixedly connected to the four corners of the bottom of the base plate 1. A brake pad is provided on one side of each caster. The water supply assembly 2 includes a water tank 21. A high-pressure water pump 22 is connected to one side of the top of the water tank 21 via a pipe. The outlet pipe of the high-pressure water pump 22 is connected to a flexible hose. An inlet pipe is connected to the other side of the top of the water tank 21. A cap is threadedly connected to the top of the inlet pipe. Push handles 23 are fixedly connected to both the front and rear ends of the other side of the water tank 21. Limiting pipes 39 are fixedly connected to both the front and rear ends of the bottom of the mounting bracket 34. A limiting rod 310 is threadedly connected to the inner cavity of the limiting pipe 39. The bottom of the limiting rod 310 is fixedly connected to the top of the base plate 1. The reciprocating component 38 includes a drive disc 381 fixedly connected to the motor 37. The drive disc 381... Both the outer and inner sides of the inner cavity are fixedly connected with fan-shaped teeth. The inner cavity of the fan-shaped teeth meshes with a follower gear 382. The top of the follower gear 382 is fixedly connected with a drive shaft 383. The surface of the drive shaft 383 is fixedly connected to the top of the mounting plate 35 through a bearing seat. The top of the mounting plate 35 is fixedly connected with a protective cover 384 by bolts. The top of the protective cover 384 has an opening through the drive shaft 383. A handle is fixedly connected to one end of the drive shaft 383 at the top of the protective cover 384. Rotating rods are fixedly connected to both sides of the surface of the threaded sleeve 41. A handle is fixedly connected to the top of the nozzle 5. A rubber sleeve is fitted on the surface of the handle. A connecting seat is fixedly connected to the bottom of the motor 37. The top of the connecting seat is fixedly connected to the bottom of the mounting plate 35.

[0032] Specifically: The universal wheels with brake pads allow the unit to move flexibly and be positioned stably, adapting to different terrain changes in the work site and improving equipment mobility. The water supply component 2 integrates the water tank 21, high-pressure water pump 22, and push handle 23 to form an independent water supply system. The push handle 23 facilitates manual movement of the unit. The water inlet pipe cap design prevents debris from entering and ensures clean water supply. The limit tube 39 and limit rod 310 constitute a guide mechanism to limit the radial displacement of the solenoid tube 33 during lifting and lowering, enhancing structural stability during height adjustment and preventing shaking. The reciprocating component 38 adopts a fan-shaped tooth meshing structure with the follower gear 382. The unidirectional rotation of the motor is converted into the reciprocating oscillation of the transmission shaft 383, enabling the nozzle 5 to rotate automatically left and right, expanding the cleaning coverage area. The protective cover 384 covers the transmission structure of the reciprocating component 38, preventing high-pressure water and dust from entering the gear meshing area, extending the service life of mechanical parts, and improving operational reliability. The nozzle 5 handle and rubber sleeve are ergonomically designed to reduce hand fatigue during hand operation. The rubber material enhances grip friction and prevents slippage. The connecting seat fixes the motor 37, ensuring the stability of the motor position during power transmission, reducing the impact of vibration on adjustment accuracy, and improving the durability of the mechanical system.

[0033] The working principle of this utility model is as follows: Starting motor 31 causes its output shaft to drive the lead screw 32 to rotate, and the screw tube 33 moves up and down along the axial direction of the lead screw 32. This, in turn, drives the quick-release assembly 4 and the nozzle 5 to rise and fall synchronously via the mounting bracket 34. The limiting tube 39 and the limiting rod 310 restrict the radial displacement of the screw tube 33, achieving precise stepless adjustment of the nozzle 5 height to adapt to cleaning objects of different heights. When the hydraulic push rod 36 extends or retracts, it pushes the mounting plate 35 to swing around the pin shaft, changing the angle between the nozzle 5 and the horizontal plane. The self-locking function of the hydraulic system ensures stable angle positioning, maintaining the set angle even under high-pressure jet vibration, ensuring accurate alignment of the cleaning direction with the soiled area. Motor 37 drives the drive disc 38. 1. When rotating, the outer and inner fan-shaped teeth mesh with the follower gear 382 in sequence, driving the transmission shaft 383 to swing back and forth. This is transmitted to the nozzle 5 through the threaded sleeve 41 of the quick-release assembly 4, causing it to automatically rotate left and right within a set angle range. This motion mode covers a large cleaning area, replacing manual back-and-forth swinging and improving rinsing efficiency and uniformity. When handheld operation is required, one hand holds the handle to fix the transmission shaft 383, while the other hand drives the threaded sleeve 41 to rotate by rotating the rotating rod. At this time, the screw 42 separates from the threaded sleeve 41, and the nozzle 5 maintains water supply through the hose. The operator holds the top handle for fine rinsing, realizing quick switching between the two modes without the need for additional tools or system shutdown.
