The use of vehicles often causes dust and oil to adhere to the surface of the vehicle. For the sake of beauty and travel convenience, cleaning the vehicle has become an indispensable part of the vehicle use process. In the market, vehicle cleaning is generally done by users themselves at home or in a car wash for a comprehensive cleaning process. Both of these easily cause a large amount of water resources and time waste, and cleaning the vehicle by yourself will also consume manpower. Since there are no special tools for personal cleaning of vehicles, they are generally wiped directly with towels, cleaning fluids and other items, which cannot provide convenience to users.

[0007] Furthermore, the bent parts at both ends of the handle are fixedly mounted on the outer surface of the cleaning outer box, and the long plate of the handle is parallel to the outer surface of the cleaning outer box.

[0008] The handle makes it easier for the user to take and place the entire cleaning device, making it convenient for the user to use.

[0009] Furthermore, the extrusion unit includes a flat handle, a connecting rod, an I-shaped frame, a compression spring and a support plate, the flat handle is installed on the outer side of the handle long plate away from the side of the cleaning outer box, the flat handle is fixedly connected to one end of the connecting rod, the other end of the connecting rod is fixedly connected to the I-shaped frame, the I-shaped frame is movably installed inside the extrusion chamber, one end of the connecting rod passes through the handle long plate and the cleaning outer box, the support plate is installed between two horizontal plates of the I-shaped frame, one end of the compression spring is fixedly connected to the inner surface of the I-shaped frame close to the connecting rod, the other end of the compression spring is fixedly connected to the surface of one side of the support plate close to the connecting rod, the support plate is vertically fixedly installed on the inner walls on both sides of the extrusion chamber, and the two horizontal plates of the I-shaped frame are in contact with the inner wall of the extrusion chamber.

[0010] When the user places the cleaning device on the oily area on the surface of the vehicle body, the flat handle is pressed to drive the I-frame to move downward under the transmission action of the connecting rod, and the compression spring is compressed, so that the I-frame squeezes the blocking unit, so that a small amount of cleaning liquid in the cleaning chamber flows evenly to the oily area, thereby achieving accurate cleaning of the oily area while avoiding waste of cleaning liquid.

[0011] Furthermore, the blocking unit includes a blocking rod, a blocking spring, a blocking plate, a pushing plate, a closing plate, a discharge pipe and a tension spring, the blocking rod being movably connected to the extrusion chamber, one end of the blocking rod extending into the extrusion chamber, the other end of the blocking rod being fixedly connected to the blocking plate, the blocking plate being installed in the cleaning chamber perpendicular to the sponge, the movement direction of the blocking plate being parallel to the sponge, one end of the blocking spring being fixedly connected to the extrusion chamber, the other end of the blocking spring being fixedly connected to the blocking plate, there being multiple pushing plates, and the pushing plates being vertically fixedly installed away from the sponge.

[0012] When the extrusion unit moves to contact with the blocking rod, the blocking rod pushes the blocking plate to move and squeeze the cleaning liquid inside the cleaning chamber, while the blocking spring is stretched. At the same time, the movement of the blocking plate drives the pushing plate to move, thereby squeezing the closing plate to move upward along the through groove opened inside the cleaning chamber, thereby opening the through hole, allowing a small amount of cleaning liquid to flow out through the discharge pipe to the oil stain on the surface of the vehicle body, thereby achieving precise cleaning of the oil stain. When the extrusion unit is not in contact with the blocking rod, the blocking spring contracts under the action of its own restoring force and drives the blocking plate to move in the opposite direction to the initial position. At the same time, the closing plate moves downward under the action of its own gravity to block the discharge pipe. When the user contacts the extrusion unit, under the action of the restoring force of the compression spring, the I-frame squeezes the blocking rod for the second time, thereby achieving a secondary small amount of uniform outflow of cleaning liquid, thereby avoiding waste caused by the outflow of cleaning liquid.

[0013] Furthermore, the cleaning unit includes a driving motor, a transmission rod, a sun gear, a planetary gear, a planetary gear ring, a cleaning brush and a cross-rotating frame.

[0014] After the blocking unit discharges the cleaning fluid to the oily area on the vehicle surface, the user places the cleaning unit of the cleaning device above the cleaning fluid and starts the driving motor. Under the action of the transmission rod, the sun gear is driven to rotate, thereby driving the planetary gears meshing with it to rotate while revolving around the planetary gear ring, and finally driving the cleaning brush to rotate, and automatically cleaning the oily area, which saves manpower and improves the cleaning efficiency. After the oily area is cleaned, the cleaning fluid is wiped off with a sponge to clean the vehicle surface.

[0015] Furthermore, one end of the blocking rod extending into the extrusion cavity is wedge-shaped.

[0016] In order to squeeze out the cleaning liquid more easily, the end of the blocking rod extending into the extrusion chamber is set to be wedge-shaped, so that the extrusion unit can squeeze the blocking rod more easily.

[0017] Furthermore, the material of the cleaning brush mounting end is a magnet, the material of the sun gear is iron, and the material of the planetary gear is iron.

[0018] In order to facilitate the cleaning and replacement of the cleaning brush, the material of the cleaning brush installation end is a magnet, which is convenient for the removal and replacement of the cleaning brush.

When the I-frame 63 is not in contact with the blocking rod 71, the blocking spring 72 contracts under the action of its own restoring force, driving the blocking plate 73 to move in the opposite direction to the initial position. At the same time, the closing plate 75 moves downward under the action of its own gravity to block the discharge pipe 76. When the user touches the extrusion unit 6, the I-frame 63 squeezes the blocking rod 71 for the second time under the action of the restoring force of the compression spring 64, thereby achieving a secondary small amount of uniform outflow of the cleaning liquid, avoiding waste caused by the outflow of the cleaning liquid.
