[0041] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0042] It should be noted that the illustrations provided in the following embodiments are only used to schematically illustrate the basic concept of the present invention, and thus the illustrations only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0043] A high-pressure cleaner is a device that uses high-pressure water to clean surfaces. It is usually used to clean buildings, cars, industrial equipment, and other surfaces. The structure of a high-pressure cleaner generally includes main components such as a water pump, an engine or motor, a water tank, a high-pressure hose, a cleaning gun, a nozzle, and a control panel. The core component of a high-pressure cleaner is a water pump, which is used to extract water from a water source and pressurize it to produce a high-pressure water flow. The water pump usually adopts a plunger pump or a piston pump structure, which can provide high pressure and stable water flow. The engine or motor is used to drive the water pump to work. The engine is usually an internal combustion engine, and gasoline or diesel can be used as fuel. The water tank stores the water source required for cleaning. Some high-pressure cleaners can also be directly connected to the tap water pipe. The high-pressure hose transfers water from the water pump to the cleaning gun, and is usually resistant to high pressure and wear. The cleaning gun is used to control the direction and intensity of the water flow. It usually has a trigger, and the high-pressure water flow will only be released when the trigger is pressed. The nozzle is installed on the cleaning gun, which can change the shape and intensity of the water flow. There are usually different models to choose from. The control panel is used to control the operation of the high-pressure cleaner, including starting and stopping, adjusting the pressure of the water flow, etc. The principle of a high-pressure cleaner is to use a water pump to pressurize water to generate a high-pressure water flow. After the high-pressure water flow passes through the cleaning gun and nozzle, it forms a water column with a high impact force, which can effectively clean the surface. The trigger on the cleaning gun controls the release of the high-pressure water flow. Users can adjust the water pressure and spray mode as needed.

[0044] High-pressure cleaners have a wide range of application scenarios, for example: used to clean building exterior walls, glass curtain walls and other surfaces, to remove dirt, dust and paint; used to clean car exterior surfaces and wheels, to remove mud, oil and other dirt, to keep the car appearance clean; used to clean agricultural machinery, livestock and poultry houses, orchard spraying equipment, etc., to keep agricultural facilities clean; used to clean hull surfaces, cabins, decks, etc., to remove marine organisms and dirt; used to clean outdoor places such as terraces, swimming pools, garden paths, to remove dirt and plant residues; used to clean public places such as roads, sidewalks, squares, etc., to remove garbage, dirt and oil.

[0045] However, the high-pressure cleaning machines in the prior art generally use a high-pressure water gun to clean the road surface; or a floor brush is configured on the water gun, and the reverse thrust of the high-pressure water flow is used to passively drive the rotating body of the floor brush to rotate to clean the road surface; or a hand-push floor brush is used in conjunction with a high-pressure cleaning machine, and the high-pressure water flow is used to passively drive the rotating body of the floor brush to rotate to clean the road surface. These cleaning methods have low working efficiency and poor cleaning effects, and users are prone to fatigue. They are not suitable for larger work scenes such as roads, parks, squares, sidewalks, etc., and are only suitable for small scenes in family courtyards.

[0046] To this end, the utility model provides a multifunctional cleaning tool, which is based on a carrier with an on-the-spot steering function and is equipped with an active rotating floor brush. Due to the on-the-spot steering body, the cleaning work is easier and more convenient, and can adapt to more and more complex cleaning scenes; due to the use of an actively rotating floor brush, the rotation speed of the floor brush can be actively adjusted and matched according to the vehicle speed to achieve the best cleaning effect; at the same time, the machine is equipped with a high-pressure water gun that can be used separately, which can be used to separately clean various corners or dead corners that cannot be cleaned; the cleaning tool is equipped with two working modes, which can not only clean the road surface in the form of a floor brush, but also clean various dead corners separately when the floor brush is stopped, thereby improving the cleaning efficiency and reducing the labor intensity of the operator.

When the pull rod 73 lifts the floor brush holder 31 to the highest position within the stroke, the hook 736 can be clamped on the hanging pin 737 under the action of the elastic element. For details, refer to Fig. 9As shown, the right end of the hook 736 is provided with an inclined surface, and the handle portion 731 is provided with a limiting structure for limiting the movement stroke of the push rod. The limiting structure can keep the above-mentioned inclined surface at a position relative to the hanging pin 737 when the hook 736 is disengaged from the hanging pin 737. When the operator pulls up the handle portion 731, the hanging pin 737 first conflicts with the above-mentioned inclined surface, causing the right end of the hook 736 to swing upward, and at the same time, the elastic element accumulates force; the operator continues to pull up the handle portion 731 to disengage the hanging pin 737 from the above-mentioned inclined surface. At this time, the right end of the hook 736 swings downward under the action of the elastic element, so that the groove of the hook 736 is stuck on the hanging pin 737, thereby locking the position of the pull rod 73. During the whole process, the operator only needs to perform the pulling operation. When it is necessary to drive the floor brush bracket 31 to descend, the operator first presses the push rod 735, at which time the push rod 735 can drive the hook 736 to swing, so that the right end of the hook 736 is separated from the hook pin 737, and then the pull rod 73 is released. The pull rod 73 will swing downward under the gravity of the floor brush bracket 31. At this time, as long as the locking pin 734 is inserted into the specific pin hole 733, the pull rod 73 can be blocked at a specific angle, so that the floor brush bracket 31 stays at a specified height; the elastic element can be installed inside the handle 731. When an emergency occurs, the operator can quickly lift the floor brush assembly 30 to the highest position, and the locking mechanism can quickly keep the floor brush assembly 30 in the highest position; when it is necessary to lower the floor brush assembly 30, the operator only needs to press the push rod 735 to separate the hook 736 from the hook pin 737, which is simple and quick to operate.
