Description

Technical Field

[0001] This utility model relates to the field of high-pressure cleaning equipment technology, and specifically discloses a high-pressure cleaner that is easy to move. Background Technology

[0002] High-pressure washers are devices that use high-pressure water jets for cleaning operations and are widely used in industrial cleaning, vehicle cleaning, and floor cleaning. Because they typically consist of heavy components such as high-pressure water pumps, water tanks, and motors, their overall structure is quite large, making them difficult to move, which is a common problem in practical use.

[0003] Several existing technologies have improved the mobility of high-pressure washers. For example, Chinese invention patent CN110681636A discloses a high-pressure washer that is easy to move. This is achieved by installing support boxes, wheels, support blocks, and lifting components at the four corners of the equipment's bottom, enabling both movement and fixed positioning. This solution uses a servo motor to drive a threaded rod to raise and lower, controlling the contact or separation of the support blocks from the ground, thereby switching between moving and stable placement states.

[0004] However, this existing technology has poor shock absorption during movement, especially when pushed on uneven ground, where the equipment is prone to significant vibration, affecting the lifespan of internal components. Furthermore, its support structure lacks a cushioning mechanism during movement, which may lead to equipment shaking or excessive noise.

[0005] Therefore, it is necessary to provide a high-pressure washer that has better cushioning and shock absorption performance, more stable structure, and is easy to deploy during movement, in order to improve user experience and equipment reliability. Utility Model Content

[0006] This invention proposes a portable high-pressure washer. Through lifting and switching and a multi-stage buffer mechanism, the high-pressure washer can be moved easily and parked stably, while effectively reducing vibration and impact during operation and movement, which significantly improves the reliability, comfort of operation and service life of the equipment.

[0007] This utility model is implemented as follows: a portable high-pressure washer includes a housing and a high-pressure water pump mounted on the top of the housing. The bottom of the housing has a receiving cavity, with through slots at each of the four corners of the bottom of the receiving cavity. A lifting device is mounted on the top of the receiving cavity corresponding to each through slot. The telescopic end of the lifting device is connected to a buffer mechanism that can move up and down within the through slots. A drive wheel is mounted on the bottom of the buffer mechanism. The buffer mechanism includes a lifting plate fixedly connected to the telescopic end of the lifting device, a buffer plate located below the lifting plate, a damper connecting the lifting plate and the buffer plate, and at least two symmetrically arranged guide components. Each guide component includes a guide rod and a buffer spring sleeved on the guide rod. The lower end of the guide rod is fixedly connected to the buffer plate, and the upper end slides through the lifting plate. The two ends of the buffer spring abut against the lifting plate and the buffer plate, respectively.

[0008] As a preferred embodiment of this utility model of a portable high-pressure washer, the top of the drive wheel is provided with a rotating shaft seat, and the bottom of the buffer plate is provided with an installation groove adapted to the rotating shaft seat. The rotating shaft seat is rotatably mounted in the installation groove via a bearing.

[0009] As a preferred embodiment of this utility model of a portable high-pressure cleaner, a pressure cap is fixedly provided at the opening of the mounting groove to prevent the bearing from falling out.

[0010] As a preferred embodiment of this utility model of a portable high-pressure washer, the bottom of the casing is provided with multiple wear-resistant feet.

[0011] As a preferred embodiment of this utility model of a portable high-pressure washer, a push-pull handle is provided on one side of the housing, and a protective frame is provided around the high-pressure water pump and fixedly connected to the top of the housing.

[0012] As a preferred embodiment of this utility model of a portable high-pressure washer, a waterproof cover is fixedly installed on the top of the protective frame, an electrical control box is installed at the bottom of the waterproof cover, and an operation display panel electrically connected to the electrical control box is provided on the side of the waterproof cover facing the push-pull handle.

[0013] As a preferred embodiment of this utility model of a portable high-pressure washer, the lifting device is an electric push rod or a cylinder.

[0014] The beneficial effects of this utility model are: 1. The lifting device allows for quick and effortless switching between moving and stationary states, greatly reducing the user's workload.

[0015] 2. The buffer mechanism effectively filters out most of the vibration and impact during movement, protecting precision components such as high-pressure water pumps and motors, and extending the service life of the equipment. The guide components ensure the stability of the shock absorption process and prevent uneven wear of components. The shock absorption function makes pushing easier and smoother. The operation display panel makes control intuitive and convenient, improving the overall user experience. All moving and buffering components are integrated into the receiving cavity at the bottom of the casing, without occupying extra space, making the overall structure of the equipment compact and beautiful.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-3A portable high-pressure washer includes a housing 1 and a high-pressure water pump 2 located on the top of the housing 1. The bottom of the housing 1 has a receiving cavity 3, and each of the four corners of the bottom of the receiving cavity 3 has a through groove 4. A lifting device 5 is provided at the top of the receiving cavity 3 corresponding to each through groove 4. The telescopic end of the lifting device 5 is connected to a buffer mechanism 6 that can move up and down within the through groove 4. The bottom of the buffer mechanism 6 is provided with a drive wheel 7. The buffer mechanism 6 includes a lifting plate 8 fixedly connected to the telescopic end of the lifting device 5, a buffer plate 9 located below the lifting plate 8, a damper 10 connecting the lifting plate 8 and the buffer plate 9, and at least two symmetrically arranged guide components 11. The guide component 11 includes a guide rod 12 and a buffer spring 13 sleeved on the guide rod 12. The lower end of the guide rod 12 is fixedly connected to the buffer plate 9, and the upper end slides through the lifting plate 8. The two ends of the buffer spring 13 abut against the lifting plate 8 and the buffer plate 9, respectively.

[0023] In this embodiment: when the equipment needs to be moved, the telescopic end of the lifting device 5 extends downward, pushing the entire buffer mechanism 6 and drive wheel 7 downward, passing through the through groove 4 until the drive wheel 7 contacts the ground and lifts the machine body, causing the wear-resistant support feet 18 at the bottom of the casing 1 to leave the ground; at this time, the weight of the equipment is entirely borne by the four drive wheels 7, and the high-pressure washer can be moved by pushing and pulling the handle 19; when the equipment needs to be fixed for operation or parking, the telescopic end of the lifting device 5 retracts upward, pulling the buffer mechanism 6 and drive wheel 7 upward back into the receiving cavity 3; the equipment body descends, and is finally stably supported on the ground by the wear-resistant support feet 18. When the device is pushed in "fixed mode" and encounters an uneven road surface, the impact is transmitted to the buffer plate 9 through the drive wheel 7. The buffer plate 9 transmits the impact force upward, compressing the damper 10 and the buffer spring 13. The damper 10 quickly absorbs and dissipates most of the impact energy, and the buffer spring 13 undergoes elastic deformation to store and release some energy. The guide rod 12 ensures that the buffer plate 9 moves up and down in a straight line to prevent jamming. Through this series of actions, the violent impact is converted into a smooth, small-amplitude relative movement between the buffer plate 9 and the lifting plate 8, thereby effectively isolating the vibration transmitted to the housing 1 and internal components.

[0024] As a technical optimization of this utility model, the top of the drive wheel 7 is provided with a rotating shaft seat 14, and the bottom of the buffer plate 9 is provided with an installation groove 15 that is adapted to the rotating shaft seat 14. The rotating shaft seat 14 is rotatably disposed in the installation groove 15 through the bearing 16.

[0025] In this embodiment: the drive wheel 7 can be flexibly steered, improving the maneuverability of the equipment when it moves, and adapting to the steering needs of narrow spaces or complex paths.

[0026] As a technical optimization of this utility model, a pressure cover 17 is fixedly provided at the groove opening of the mounting groove 15 to prevent the bearing 16 from falling out.

[0027] In this embodiment: a pressure cap 17 is added to prevent the bearing 16 from coming off, thereby enhancing the stability and safety of the drive wheel 7 connection structure and preventing equipment failure caused by the bearing 16 falling off during movement.

[0028] As a technical optimization of this utility model, the bottom of the housing 1 is provided with multiple wear-resistant feet 18.

[0029] In this embodiment: the support legs prevent the drive wheel 7 from being deformed by long-term stress, while improving placement stability and extending service life with wear-resistant materials.

[0030] As a technical optimization of this utility model, a push-pull handle 19 is provided on one side of the housing 1, and a protective frame 20 is provided around the high-pressure water pump 2 and fixedly connected to the top of the housing 1.

[0031] In this embodiment: the push-pull handle 19 improves ease of movement; the protective frame 20 protects the high-pressure water pump 2 and reduces the risk of collision damage.

[0032] As a technical optimization of this utility model, a waterproof cover 21 is fixedly installed on the top of the protective frame 20, an electrical control box 22 is installed at the bottom of the waterproof cover 21, and an operation display panel 23 electrically connected to the electrical control box 22 is provided on the side of the waterproof cover 21 facing the push-pull handle 19.

[0033] In this embodiment: the waterproof cover 21 protects the electrical control box 22 from water immersion or dust; the operation panel improves the convenience of users adjusting parameters and enhances the intelligent operation experience of the equipment.

[0034] As a technical optimization of this utility model, the lifting device 5 is an electric push rod or a cylinder.

[0035] In this embodiment, both the electric push rod and the cylinder have the characteristics of controllable extension and retraction stroke and stable output force, which can ensure that the lifting and lowering action of the drive wheel 7 can be precisely controlled. The rated thrust of the electric push rod is not less than 500N, and the working air pressure range of the cylinder is 0.6-0.8MPa.

[0036] Working principle and usage process of this utility model: The lifting device 5 is extended via the electrical control box 22 or manual control, and the drive wheel 7 extends from the through groove 4 and contacts the ground, lifting the entire equipment and removing the wear-resistant support 18 from the ground. The user pushes the push-pull handle 19, and the drive wheel 7 flexibly turns through the rotating shaft seat 14 to adapt to different paths. When encountering uneven ground, the buffer spring 13 of the buffer mechanism 6 is compressed / extended, working with the damper 10 to absorb vibration and keep the equipment stable. After reaching the work site, the lifting device 5 is retracted, the drive wheel 7 retracts into the receiving cavity 3, the wear-resistant support 18 contacts the ground, and the equipment is placed stably. The high-pressure water pump 2 is started via the operation display panel 23, and the working parameters (such as pressure and flow rate) are adjusted to use high-pressure water flow for cleaning. The protective frame 20 and the waterproof cover 21 protect the water pump and the electrical control box 22, respectively.
