Technical Field

[0001] The present application relates to the field of cleaning machines, and in particular to a multifunctional portable high-pressure cleaning machine. Background Art

[0002] High-pressure cleaners are widely used in the car washing industry. The steps of car washing usually include the following: 1. Pre-washing, pre-treating the vehicle with pre-washing liquid to soften the dirt for subsequent cleaning; 2. Rinse, use a high-pressure water gun to rinse the car body to remove most of the dust and dirt; 3. Mix special car washing liquid with water and spray it evenly on the car body; 4. Gently wipe the car body with a sponge or car washing brush to remove stubborn stains; 5. Rinse the car body with clean water to ensure that all the car washing liquid is washed away; 6. Use a clean towel or car wiping cloth to wipe the car body dry to ensure that there are no water marks.

[0003] There are three types of liquids needed for car washing, namely pre-wash liquid, car washing liquid and clean water. In the related art, the car washing technology uses three high-pressure cleaning machines, each of which is connected to a liquid storage tank for a liquid. The nozzles on each high-pressure cleaning machine are different to match the use of different liquids, and different cleaning machines are used in different steps. However, there are many cleaning machines in the above technology, which leads to high costs, large space required, and relatively messy storage. It is also easy to make the wrong choice when selecting a cleaning machine, which affects the efficiency of car washing. Summary of the invention

[0006] By adopting the above technical solution, the liquid storage tank stores clean water, car washing liquid and pre-washing liquid respectively, and the option switches correspond to the use of clean water, car washing liquid and pre-washing liquid respectively. When in use, the button for clean water is selected through the option switch, and the controller controls the liquid outlet intelligent valve on the liquid outlet pipe connected to the liquid storage tank containing clean water to open, and the other liquid outlet intelligent valves are closed. At this time, clean water is sprayed out after the spray gun is opened. If car washing liquid or pre-washing liquid is needed, just select the corresponding button through the option switch to make the car washing liquid or pre-washing liquid in the spray gun for use. The nozzle conversion device can convert different nozzles, which is convenient for use in different situations and makes nozzle conversion convenient.

[0007] The present application scheme adopts a cleaning machine to realize the conversion and use of multiple liquids such as clean water, car washing liquid and pre-washing liquid, which saves costs, is convenient for nozzle conversion, and is easy to use.

[0008] Optionally, the nozzle conversion device includes a connecting part, a conversion disk rotatably arranged on the connecting part, and a plurality of nozzles arranged on the conversion disk; the connecting part is fixed to the liquid outlet end of the spray gun, and a water hole is arranged in the connecting part; the conversion disk includes a rotating part and a mounting part, the rotating part is rotatably connected to the connecting part, and a plurality of first water spray holes are arranged on the rotating part, and the water through hole is close to one end of the rotating part away from the center of the end face of the connecting part, and after the rotating part rotates, one of the first water spray holes is connected to the water through hole; a plurality of second water spray holes are provided on the mounting part, which are connected to the first water spray holes one by one, and the second water spray holes are arranged one by one corresponding to the plurality of nozzles.

[0009] By adopting the above technical solution, when switching the nozzle, the personnel hold the rotating part and rotate it, so that the first water spray hole corresponding to the corresponding nozzle is connected to the water through hole, thereby realizing the switching of the nozzle, which makes it convenient to change. The end of the water through hole close to the rotating part is far away from the center of the end face of the connecting part, so that the axis of the rotating part can be conveniently set to be coaxial with the connecting part, and the spray chamber has a better feel. When spraying water, the liquid passes through the spray gun, the water through hole, the first water spray hole, the second water spray hole and the nozzle in sequence.

[0010] Optionally, an elastic card block is provided on the connecting part toward the rotating part, and a plurality of slots for the elastic card block to be engaged are provided on the rotating part, and the slots are provided corresponding to the first water spray holes. When the elastic card block is engaged in the slots, one of the first water spray holes is connected to the water through hole.

When the leak-proof tube is inserted into the first water spray hole, the sealing ring is located on the side of the connecting port away from the first water spray hole, so that the leak-proof tube and the inner wall of the water hole are well sealed. When the nozzle needs to be changed, the leak-proof tube is separated from the first water spray hole by sliding the toggle part away from the rotating part.

[0016] Optionally, a chamfer is provided on the outer periphery of one end of the leak-proof tube close to the rotating part.

[0017] By adopting the above technical solution, the leak-proof pipe can be inserted into the first water spray hole smoothly.

[0018] Optionally, a push piece is fixed on the toggle portion, the push piece closes the side groove, and the push piece slides to contact the outer wall of the connecting portion.

[0019] By adopting the above technical solution, the push sheet closes the side groove, making it difficult for dirt to enter the side groove.

[0020] Optionally, the outer side wall of the push sheet is provided with a first anti-slip pattern.

[0021] By adopting the above technical solution, the pushing piece can slide easily.

[0022] Optionally, the outer wall of the connecting part is provided with a first indicator mark and a second indicator mark, the first indicator mark is located on the side of the side groove close to the rotating part, and the first indicator mark indicates that the rotating part is in a locked state, and the second indicator mark is located on the side of the side groove away from the rotating part, and the second indicator mark indicates that the rotating part is in an unlocked state.
