DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, an embodiment provided by the present utility model: an auto fender self-cleaning structure, including a fender body 1 and a branch pipe 6. Three branch heads 9 are evenly arranged on the outer side of the branch pipe 6. One end of the branch head 9 away from the branch pipe 6 is threadedly connected with a telescopic valve body 10. One end of the telescopic valve body 10 away from the branch head 9 is threadedly connected with a spray head 11. A spring 12 is fixedly connected to the middle part of the inner side of the telescopic valve body 10. One end of the spring 12 away from the telescopic valve body 10 is fixedly connected with a push-pull ring 13. Two limit sliders 17 are symmetrically fixedly connected to both sides of the push-pull ring 13. One end of the push-pull ring 13 away from the spring 12 is fixedly connected with a hidden valve core 14. The hidden valve core 14 is elastically pulled by the spring 12 to contract inside the spray head 11, so as to prevent soil from entering the inside of the spray head 11 and blocking the water spray orifice.

[0021] A diversion groove 15 is opened at one end of the top of the hidden valve core 14 close to the push-pull ring 13. The diversion groove 15 is designed in an arc shape, which is convenient for guiding the water flow for spraying. Limit sliding grooves 16 are symmetrically opened on the inner side of the spray head 11. The limit sliders 17 are limited through the limit sliding grooves 16 to prevent the hidden valve core 14 from moving to the outside of the spray head 11 and unable to rebound.

[0022] A connecting hose 5 is fixedly installed at the input end of the branch pipe 6. One end of the connecting hose 5 away from the branch pipe 6 is fixedly installed with a small high-pressure water pump 4. The small high-pressure water pump 4 is electrically connected to the driver's control center by wire, which is convenient for the driver to control the start of the small high-pressure water pump 4 to wash the fender body 1 at any time. The driver turns on the small high-pressure water pump 4 through the control terminal. The small high-pressure water pump 4 pumps out the water in the water tank and transports it to the inside of the branch pipe 6 through the connecting hose 5. The water in the branch pipe 6 is transported to the inside of the diversion groove 15 through the branch head 9 to push out the hidden valve core 14 from the spray head 11 to wash the fender body 1.

[0023] Mounting holes 2 are evenly penetrated through the fender body 1. A protective frame 7 is fixedly installed at the bottom end of the top of the fender body 1. A placement groove 8 is opened on one side of the protective frame 7 away from the fender body 1. A protective plate 3 is fixedly installed on one side of the protective frame 7 close to the placement groove 8. A groove matching the branch pipe 6 is opened on one side of the protective plate 3 close to the protective frame 7. The branch pipe 6 is fixed through the protective frame 7 and the protective plate 3, and the spray head end of the spray head 11 is located at the inner top end of the fender body 1. The telescopic valve body 10 and the spray head 11 are protected by the protective plate 3 and the protective frame 7 to avoid being impacted by large-particle debris carried by the wheels.

[0024] The push-pull ring 13 and the hidden valve core 14 are slidably connected to the inside of the nozzle 11. The limit slider 17 is slidably connected to the inside of the limit chute 16. The water in the branch pipe 6 pushes the hidden valve core 14 to drive the push-pull ring 13 to move and pulls the spring 12 to stretch. The movement of the push-pull ring 13 drives the limit slider 17 to slide inside the limit chute 16 to the end of the nozzle 11 away from the telescopic valve body 10. At this time, the top of the diversion groove 15 extends out of the inside of the nozzle 11, and the water sprays out through the diversion groove 15 and splashes on the inside of the fender body 1.

[0025] Working principle: During use, first place the branch pipe 6 inside the placement groove 8 and install the protective plate 3 on the protective frame 7 to fix the branch pipe 6. Then install the protective frame 7 at the bottom end of the top of the fender body 1. Then install the fender body 1 on the vehicle diagonally above the wheel. Then place the small high-pressure water pump 4 inside the water tank of the vehicle. When there is mud accumulated on the fender body 1 during vehicle driving and it needs to be cleaned, the driver turns on the small high-pressure water pump 4 through the control terminal. The small high-pressure water pump 4 pumps out the water in the water tank and transports it to the inside of the branch pipe 6 through the connecting hose 5. The water in the branch pipe 6 is transported to the inside of the telescopic valve body 10 through the branch head 9. At this time, the water inside the telescopic valve body 10 enters the inside of the diversion groove 15 and pushes the hidden valve core 14 to move away from the telescopic valve body 10 inside the nozzle 11. At the same time, the hidden valve core 14 drives the push-pull ring 13 to move and pulls the spring 12 to stretch. The movement of the push-pull ring 13 drives the limit slider 17 to slide inside the limit chute 16 to the end of the nozzle 11 away from the telescopic valve body 10. At this time, the top of the diversion groove 15 extends out of the inside of the nozzle 11, and the water sprays out through the diversion groove 15 and splashes on the inside of the fender body 1, flushing the mud accumulated on the inside of the fender body 1. Since the fender body 1 is arc-shaped, the water sprayed out by the diversion groove 15 flushes downward according to the inside of the fender body 1, washing away the mud on the inside of the fender body 1, thereby realizing the flushing of the fender body 1. When the flushing is completed, control the small high-pressure water pump 4 to close. After the small high-pressure water pump 4 is closed, the water flow is interrupted, and the hidden valve core 14 loses the impact force of the water and cannot pull the spring 12. At this time, the spring 12 contracts to drive the push-pull ring 13 to approach the telescopic valve body 10. The movement of the push-pull ring 13 drives the hidden valve core 14 to move closer to the telescopic valve body 10 until the hidden valve core 14 completely enters the inside of the nozzle 11 and returns to the initial state.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
