Description

Technical Field

[0001] The invention relates to the technical field of cleaning devices, and in particular to a vehicle cleaning device for public transportation in scenic spots. Background Art

[0002] In large parks, there are some buses for tourists to enjoy the sights. However, the dust on the road will make the buses dirty during use. Using high-pressure water pipes to wash them is not very thorough. People usually wipe them with a towel, which is more troublesome.

[0003] To this end, the Chinese patent with the publication number "CN214267567U" announced "a vehicle cleaning device", whose main structure includes a cylinder, a hand-held rod, a partition, a first cavity, a second cavity, a connecting cylinder, a first rotating plate, a second rotating plate, a rotating shaft, a sponge layer and a water outlet. The vehicle cleaning device can clean the car without people touching the water. Through the combination of the sponge layer and the plush strip, the plush strip is easier to foam, which is convenient for the use and application of the cleaning agent. The sponge layer can well remove the foam of the cleaning agent and the dust on the car, making cleaning convenient and efficient.

[0004] However, during the cleaning process, the user needs to apply force in two directions to the handheld rod. First, it is to adjust the overall height of the equipment, which is the longitudinal force; second, it is to make the sponge layer act on the surface of the vehicle, which is the lateral force. The manipulation of the two forces will increase the labor intensity of the staff and will also lead to low cleaning efficiency during the cleaning process. Summary of the invention

[0031] To achieve a water spray wipe effect on your vehicle, see Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up a water spray wiping mechanism 7, which is provided with a No. 1 hollow shell 71 fixedly installed in the No. 1 fixed cavity 6 and capable of allowing liquid to flow along the inside of the structure, a hollow rotating shaft 75 rotatably installed in the center of the No. 1 hollow shell 71 and capable of transmitting water flow from the inside of the No. 1 hollow shell 71, a rotating disk 77 arranged at one end of the hollow rotating shaft 75 and capable of rotating with the hollow rotating shaft 75, and an annular sponge 79 embedded in one end surface of the rotating disk 77 and capable of rotating with the rotating disk 77.

[0032] For the specific structure of the water spray wiping mechanism 7, please refer to Figure 3 and Figure 4 , including a No. 1 hollow shell 71 with a part of the outer circumference fixedly installed in the No. 1 fixed cavity 6, the interior of the No. 1 hollow shell 71 is provided with an annular liquid flow cavity 73, the circumferential surface of the No. 1 hollow shell 71 is provided with a liquid injection channel 74 connecting the external space and the annular liquid flow cavity 73, both ends of the No. 1 hollow shell 71 are provided with a No. 1 component mounting hole 72, the shaft body of the hollow rotating shaft 75 passes through the two No. 1 component mounting holes 72 and the annular liquid flow cavity 73, and the shaft body of the hollow rotating shaft 75 is installed inside the No. 1 component mounting hole 72 through a mechanical sealing structure, one end of the hollow rotating shaft 75 is provided with a No. 1 shaft body fixing groove 76 with an inner concave structure, and the hollow rotating shaft The other end face of the moving shaft 75 is provided with a rotating disk 77 with an integral structure therewith, and a liquid discharge hole 710 with one end being open is provided in the center of the hollow rotating shaft 75 and the rotating disk 77, and a liquid flow hole 711 connecting the liquid discharge hole 710 and the annular liquid flow chamber 73 is provided inside the hollow rotating shaft 75, and an annular embedding groove 78 is provided on one end face of the rotating disk 77 at the periphery of the open end of the liquid discharge hole 710, and an annular sponge 79 is fixedly embedded in the rotating disk 77 at the inside of the annular embedding groove 78. In order for the annular sponge 79 to be able to perform wiping work with the protruding portion, it is necessary to make the thickness of the annular sponge 79 greater than the depth of the annular embedding groove 78.

[0033] To achieve the necessary pressure and rotation effect, see Figure 1 , Figure 2 , Figure 5 and Figure 6, a gas driving mechanism 8 is required, wherein a second hollow shell 81 is provided inside the second hollow shell 81 fixedly installed in the first fixed cavity 6 and capable of causing the gas to flow along the inside of the structure, a turbine blade 89 installed inside the second hollow shell 81 and generating a rotation effect after being acted upon by the gas, and a first rotating shaft 87 fixedly installed at the center of the turbine blade 89 and capable of transmitting the rotation effect.

Since the aperture of the conical gas discharge hole 86 at one end of the annular gas flow chamber 82 is larger than the aperture of the end away from the annular gas flow chamber 82, the accelerated flow of the exhaust gas forms a reaction force, so that the annular sponge body 79 can act on the vehicle surface with a certain pressure to generate the required pressure, and the rotating No. 1 rotating shaft 87 will indirectly drive the annular sponge body 79 to rotate, thereby achieving a wiping effect on the vehicle surface.

[0034] For the specific structure of the gas drive mechanism 8, please refer to Figure 5 and Figure 6 , including a second hollow shell 81 with a part of its outer circumference fixedly installed in the first fixed cavity 6, the second hollow shell 81 is provided with an annular gas flow cavity 82 inside, the center of one end surface of the second hollow shell 81 is provided with a second component mounting hole 83, the other end surface of the second hollow shell 81 is provided with a gas discharge pipeline 85 with an integral structure therewith, the gas discharge pipeline 85 is provided with a conical gas discharge hole 86 connecting the annular gas flow cavity 82 and the external space, the circumferential surface of the second hollow shell 81 is provided with an integral structure therewith and connecting the annular gas flow cavity 82 and the external space The gas injection channel 84 is formed on the circumferential surface of the cavity 82, and the No. 2 hollow shell 81 is provided with a rotatable No. 1 rotating shaft 87 inside the No. 2 component mounting hole 83 through a mechanical sealing structure, and one end of the No. 1 rotating shaft 87 is provided with a No. 2 shaft body fixing groove 88 with an inner concave structure, and the other end of the No. 1 rotating shaft 87 is located inside the annular gas flow cavity 82, and the No. 1 rotating shaft 87 is fixedly provided with turbine blades 89 outside the shaft body located inside the annular gas flow cavity 82, and one end of the No. 1 rotating shaft 87 is provided with a tip structure 810 for guiding the gas flow.

[0035] To achieve a controlled deceleration effect with linkage force, see Figure 2 , Figure 7 and Figure 8, it is necessary to set up a pressure-controlled speed reduction mechanism 9, which is provided with a No. 1 rotating wheel 95 fixedly connected to the No. 1 rotating shaft 87, a No. 2 rotating wheel 96 fixedly connected to the hollow rotating shaft 75, a No. 3 rotating wheel 99 that contacts the circumferential surface of the No. 1 rotating wheel 95 and can transmit the rotation speed of the No. 1 rotating wheel 95 backward in the form of reduced speed, a No. 4 rotating wheel 910 that contacts the circumferential surface of the No. 2 rotating wheel 96 and can transmit the rotation speed of the No. 3 rotating wheel 99 backward in the form of reduced speed, and a No. 4 rotating shaft 911 that makes the No. 3 rotating wheel 99 and the No. 4 rotating wheel 910 contact the circumferential surfaces of the No. 1 rotating wheel 95 and the No. 2 rotating wheel 96 with the pressure required to transmit the rotation effect, the No. 1 rotating shaft 87 will drive the No. 1 rotating wheel 95 to rotate, because the No. 1 rotating wheel 95, the No. 2 rotating wheel 96, the No. 3 rotating wheel 99 and the No. 4 rotating wheel 910 are all wear-resistant and friction-resistant The material with high friction coefficient is used, and the structural radius of the No. 1 rotating wheel 95 is smaller than the structural radius of the No. 3 rotating wheel 99, the structural radius of the No. 3 rotating wheel 99 is larger than the structural radius of the No. 4 rotating wheel 910, and the structural radius of the No. 4 rotating wheel 910 is smaller than the structural radius of the No. 2 rotating wheel 96. After the rotation speed of the No. 1 rotating shaft 87 is reduced, the hollow rotating shaft 75 rotates at a lower speed, so that the annular sponge 79 performs a wiping action at an appropriate speed. At the same time, once the torque resistance during the wiping process is greater than the pressure provided by the threaded spring 917, relative rotation will occur between the No. 1 rotating wheel 95, the No. 2 rotating wheel 96, the No. 3 rotating wheel 99 and the No. 4 rotating wheel 910, so that the annular sponge 79 will not perform wiping work with an overloaded torque force, thereby preventing the occurrence of damage to equipment or vehicles due to excessive torque force.
