Description

Technical Field

[0001] This utility model relates to the field of car wash machine technology, and more specifically, to a foam car wash machine. Background Technology

[0002] Foam machines, sometimes called foam car wash machines, work by mixing car wash liquid and water to form foam that is sprayed out. This prevents fine sand particles from damaging the car's paint and prolongs the time the paint stays glossy. Foam machines are suitable for car detailing, fleet cleaning, bus, train, and airplane cleaning, as well as for cleaning the exterior walls, windows, and floors of hotels and guesthouses.

[0003] The existing publication number CN218323753U discloses a foam generator for a car wash machine, including a reaction device, a foaming device, and a feeding / discharging mechanism. The foaming device is located inside the reaction device, and the feeding / discharging mechanism is located at the top of the reaction device. The foaming device agitates water and detergent, ensuring thorough mixing and enhancing the foaming effect, thus effectively improving the quality of the cleaning foam. The feeding / discharging mechanism uses a finer mesh and filler wire inside a finer tube to refine the cleaning foam, resulting in finer sprayed foam. This effectively increases the foam's adhesion time, allowing for thorough immersion of the car body, softening stains, enhancing cleaning effectiveness, and reducing detergent consumption. The inventors discovered the following problems with the existing technology during the development of this utility model:

[0004] However, the fixed position of the foam outlet tube results in a fixed position of the foam outlet holes on the foam outlet tube. When the foam outlet holes are in a fixed position, there may be certain limitations in sucking out the foam generated inside the reaction cylinder, and it may not be able to suck out the foam from different positions inside the reaction cylinder well and quickly.

[0005] Therefore, a foam car wash machine is proposed to address the above problems. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a foam car wash machine to solve the problems mentioned in the background art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 (as attached) Figures 1 to 4The foam car wash machine shown includes a foam reaction cylinder 1. A stirring rod 2 is rotatably connected inside the foam reaction cylinder 1. A drive servo motor 6 is connected to the top of the stirring rod 2 to drive the stirring rod 2, and the drive servo motor 6 is fixedly mounted on the top of the foam reaction cylinder 1 by bolts. A threaded rod 3 is provided inside the foam reaction cylinder 1 and located on one side of the stirring rod 2. A lifting block 8 is threadedly connected to the outside of the threaded rod 3. A lifting screen plate 7 is fixedly provided on the outside of the lifting block 8. The stirring rod 2 moves through the surface of the lifting screen plate 7. A suction U-shaped tube 9 is fixedly provided on the lifting screen plate 7. A connecting hose 10 is connected to the outside of the suction U-shaped tube 9. One end of the connecting hose 10 is fixedly passed through the top of the foam reaction cylinder 1. A transmission assembly is provided between the stirring rod 2 and the threaded rod 3.

[0023] Specifically, when it is necessary to extract foam from the foam reaction cylinder 1, the stirring rod 2 can be driven to rotate by the servo motor 6. Then, the stirring rod 2 drives the threaded rod 3 to rotate synchronously through the transmission component. The rotating threaded rod 3 then drives the lifting block 8 and the lifting screen plate 7 to move up and down. The moving lifting screen plate 7 drives the suction U-shaped tube 9 at one end of the connecting hose 10 set on the lifting screen plate 7 to move up and down. This allows the suction U-shaped tube 9 at one end of the connecting hose 10 to be adjusted in height to adapt to the horizontal position of the foam generated inside the foam reaction cylinder 1. During the foam generation process inside the foam reaction cylinder 1, the water and detergent can be fully mixed and stirred by the up and down moving lifting screen plate 7, thereby further enhancing its foaming effect and efficiency.

[0024] Example 2: Based on Example 1, the solution in Example 1 is further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0025] In a preferred embodiment, the transmission assembly includes pulleys 4 and a transmission belt 5. Pulleys 4 are fixedly installed on the outer sides of the top ends of the stirring rod 2 and the threaded rod 3. The two pulleys 4 are connected by the transmission belt 5. When the rotating stirring rod 2 synchronously drives the threaded rod 3, the rotating stirring rod 2 will first drive the pulleys 4 to rotate. Then, the synchronous transmission between the two pulleys 4 is achieved through the transmission belt 5 installed on the outer sides of the two pulleys 4. Finally, the rotation of the pulleys 4 sleeved on the outer side of the threaded rod 3 drives the threaded rod 3 to rotate.

[0026] In a preferred embodiment, a pipe body 12 is connected to one end of the connecting hose 10, located outside the foam reaction cylinder 1, via a screw-fit connecting block 15. A foam outlet pipe 13 is provided at the other end of the pipe body 12, and the foam outlet pipe 13 is connected to one end of the pipe body 12 via the screw-fit connecting block 15. The pipe body 12 is filled with steel wire 14. A foam outlet valve 11 is provided on the outer side of the connecting hose 10 near the pipe body 12. Foam is transported through the connecting hose 10 to the foam outlet valve 11, and then enters the pipe body 12 through the foam outlet valve 11. The filling steel wire 14 inside the tube 12 further refines the incoming foam before it is sprayed out through the foam outlet pipe 13 and applied to the vehicle surface. Simultaneously, a feed pipe 16 is installed at the top of the foam reaction cylinder 1, with a liquid pump connected to one end. This allows for the convenient pouring of external water and cleaning agents into the foam reaction cylinder 1. A feed valve 17 is installed on the feed pipe 16 to facilitate the input of water and cleaning agents. An air inlet valve 18 is installed at the bottom of the foam reaction cylinder 1, with an air intake valve... An air compressor is installed at one end of the air inlet valve 18 and an air pipe 19. An air inlet plate 20 is fixedly installed inside the foam reaction cylinder 1. The bottom end of the stirring rod 2 rotates through the surface of the air inlet plate 20. An stirring paddle 21 is installed at the bottom end of the stirring rod 2 and below the air inlet plate 20. The top end of the threaded rod 3 is rotatably connected to the top end inside the foam reaction cylinder 1, and the bottom end of the threaded rod 3 is rotatably connected to the upper surface of the air inlet plate 20. A transparent observation window 22 is provided on the surface of the foam reaction cylinder 1, through which the position of the foam inside the foam reaction cylinder 1 can be observed. When in use, turn on the air compressor. The air compressor will deliver compressed air to the foam reaction cylinder 1 through the air inlet valve 18. When the air is input, the water and cleaning liquid will tumble under the action of the air, thus mixing better. After the water and cleaning agent are mixed, cleaning foam will be generated. When the cleaning foam passes through the air inlet plate 20, the air inlet plate 20 will refine the cleaning foam once. After the foam passes through the air inlet plate 20, it will enter the suction U-shaped pipe 9 under the action of the internal pressure of the foam reaction cylinder 1. It will then enter the connecting hose 10, the pipe body 12, and finally be discharged through the foam outlet pipe 13.

[0027] In this embodiment, the liquid pump, air compressor, motor, and control valve are all commercially available devices known to those skilled in the art. They can be customized or selected according to actual needs. Here, we are only using them without making any structural or functional improvements, and we will not go into detail about them here.

[0028] The working process of this utility model is as follows: First, the stirring rod 2 can be driven to rotate by the servo motor 6. Then, the stirring rod 2 drives the pulley 4 set on the outside of the stirring rod 2 to rotate. Next, the transmission belt 5 set on the outside of the two pulleys 4 drives the pulley 4 sleeved on the outside of the threaded rod 3 to rotate, thereby realizing the synchronous rotation of the threaded rod 3. Then, the rotating threaded rod 3 drives the lifting block 8 and the lifting screen plate 7 to move up and down. The moving lifting screen plate 7 drives the U-shaped tube 9 at one end of the connecting hose 10 set on the lifting screen plate 7 to move up and down. Thus, the U-shaped tube 9 at one end of the connecting hose 10 can be adjusted to the horizontal position of the foam generated inside the foam reaction cylinder 1. In the process of foam generation inside the foam reaction cylinder 1, the water and detergent can be fully mixed and stirred by the up and down moving lifting screen plate 7, thereby further enhancing its foaming effect and efficiency. The above is the working principle of this foam car wash machine.
