[0004] Therefore, there is a need to provide a car navigation screen cleaning device with a material control mechanism. Utility Model Content

[0005] In order to overcome the shortcomings of the existing patents, which have no material control mechanism on the spray box, the spray box will continue to spray after cleaning, which may cause the cleaning liquid to be sprayed into non-target areas, resulting in waste, this utility model provides a car navigation screen cleaning device with a material control mechanism.

[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a car navigation screen cleaning device, comprising a base frame, a cleaning tank, electric conveying rollers, a water tank, a sealing cover, a water supply pipe, a pipeline pump, a ball valve, a nozzle, a protrusion, and a cleaning mechanism. The cleaning tank is fixedly connected to the base frame, and multiple electric conveying rollers are mounted on the base frame. A water tank is fixedly connected to the cleaning tank, and a sealing cover is fixedly connected to the water tank. A water supply pipe is connected to the water tank, and a pipeline pump is installed on the water supply pipe. A ball valve is rotatably mounted on the water supply pipe, and a nozzle is fixedly connected and connected to the water supply pipe. A protrusion is fixedly connected to the ball valve, and a cleaning mechanism is provided on the cleaning tank. The device also includes... The device includes a first guide rod, a guide plate, a first elastic element, a support plate, a slider, a connecting rod, and a torsion spring. Multiple first guide rods are slidably mounted on the cleaning tank. A guide plate is fixedly connected between two first guide rods. A first elastic element is fitted onto each first guide rod, with both ends of the first elastic element connected to the guide plate and the cleaning tank, respectively. A connecting rod is fixedly connected to one of the guide plates, and a slider is fixedly connected to the connecting rod. A support plate is fixedly connected to the nozzle, and a guide groove is formed on the support plate. The slider slides within the guide groove and contacts a protrusion. A torsion spring is fitted onto the ball valve, with both ends of the torsion spring connected to a water supply pipe and a protrusion, respectively.

[0007] Preferably, the cleaning mechanism includes a support base, a second guide rod, a connecting plate, a second elastic element, and a sponge brush. Two support bases are fixedly connected to the cleaning box. The second guide rod is slidably arranged on the support base. A connecting plate is fixedly connected to each of the two second guide rods. A second elastic element is sleeved on the second guide rod. The two ends of the second elastic element are respectively connected to the support base and the connecting plate. A sponge brush is rotatably arranged between the two connecting plates.

[0008] Preferably, it also includes air pipes, air nozzles, connecting pipes and connectors. Two air pipes are fixedly connected inside the cleaning box, and two connecting pipes are connected between the two air pipes. Connectors are provided on the connecting pipes, and multiple air nozzles are connected to the air pipes.

[0009] Preferably, it also includes a fixing plate, an electric heating element, a mounting bracket, and an exhaust fan. The mounting bracket is fixedly connected inside the cleaning box, and multiple exhaust fans are installed on the mounting bracket. Four fixing plates are fixedly connected inside the cleaning box, and an electric heating element is installed between the four fixing plates.

[0011] As a preferred option, a protective net is also included, with the cleaning tank being fixedly connected to the protective net.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The first elastic element rebounds and drives the guide plate and the two first guide rods to reset. While the guide plate moves, it drives the connecting rod and the slider to move inward, so that the sliding pushes the protrusion to rotate again. The torsion spring returns to its original state and also drives the protrusion to rotate. In this way, the rotation of the protrusion drives the ball valve to reverse and close, thereby achieving the effect of spraying cleaning liquid when the screen passes by, reducing waste.

[0013] 2. The car navigation screen squeezes the sponge brush upward, causing the second elastic element to be compressed and quickly rebound, which in turn moves the two connecting plates, the two second guide rods, and the sponge brush, making the sponge brush in close contact with the car navigation screen. The car navigation screen moves backward, squeezing the sponge brush to rotate, thereby enabling the sponge brush to automatically clean the car navigation screen and remove the cleaning fluid from it.

[0014] 3. By connecting the connector to the air pump, the air pump draws in outside air into the connecting pipe and delivers it into the air tube, finally blowing it out from the air nozzle. At the same time, the exhaust fan and electric heating element are activated. The exhaust fan draws in outside air, which combines with the heat on the electric heating element to form hot air, which is then blown onto the car navigation screen. This allows for multi-stage rapid drying of the car navigation screen, ensuring that there are no residues on the screen. Attached Figure Description

Detailed Implementation

[0024] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0025] Example 1: Car navigation screen cleaning device, see Figures 1-8As shown, the system includes a base frame 1, a cleaning tank 101, electric conveyor rollers 2, a water tank 3, a sealing cover 4, a water supply pipe 5, a pipeline pump 6, a ball valve 7, a nozzle 8, a protrusion 9, and a cleaning mechanism. The cleaning tank 101 is fixedly connected to the top of the base frame 1. Multiple electric conveyor rollers 2 are evenly spaced on the upper part of the base frame 1. The water tank 3 is fixedly connected to the top of the cleaning tank 101, and a sealing cover 4 is fixedly connected to the top of the water tank 3. A water supply pipe 5 is connected to the water tank 3, passing through the cleaning tank 101. A pipeline pump 6 is installed at the upper part of the water supply pipe 5, and a ball valve 7 is rotatably installed at the lower part of the water supply pipe 5. A nozzle 8 is fixedly connected and connected to the end of the water supply pipe 5, located inside the cleaning tank 101. A protrusion 9 is fixedly connected to the ball valve 7. A cleaning mechanism for cleaning car navigation screens is provided in the middle of the cleaning tank 101. The system also includes a first guide rod 10, a guide plate 11, and a first spring. The cleaning tank 101 includes a support plate 13, a slider 15, a connecting rod 16, and a torsion spring 17. Two first guide rods 10 are slidably mounted on the left and right sides of the front of the cleaning tank 101. A guide plate 11 is fixedly connected between the ends of the two first guide rods 10. The guide plate 11 is located inside the cleaning tank 101. A first elastic element 12 is fitted onto the first guide rod 10, and both ends of the first elastic element 12 are connected to the guide plate 11 and the cleaning tank 101, respectively. A connecting rod 16 is welded onto the guide plate 11 on the right side, and a slider 15 is fixedly connected to the connecting rod 16. A support plate 13 is fixedly connected to the nozzle 8, and a guide groove 14 is opened on the support plate 13. The slider 15 slides within the guide groove 14 and contacts the protrusion 9. A torsion spring 17 is fitted onto the ball valve 7, and both ends of the torsion spring 17 are connected to the water pipe 5 and the protrusion 9, respectively.

[0026] When cleaning the car navigation screen is required, first place the car navigation screen on the electric conveyor roller 2. The electric conveyor roller 2 rotates, causing the car navigation screen to move backward and squeezing the two guide plates 11 outward. The outward movement of the guide plates 11 causes the two first guide rods 10 to move outward, and the first elastic element 12 is compressed accordingly. At the same time, the guide plates 11 drive the connecting rod 16 and the slider 15 to move outward. The movement of the slider 12 causes the protrusion 9 to rotate. The rotation of the protrusion 9 causes the ball valve 7 to rotate, causing the ball valve 7 to open. The pipeline pump 6 draws the cleaning fluid from the water tank 3 into the water supply pipe 5 and sprays it onto the car navigation screen from the nozzle 8. On the screen, after the car navigation screen no longer contacts the guide plate 11, the first elastic element 12 rebounds and drives the guide plate 11 and the two first guide rods 10 to reset. While the guide plate 11 moves, it drives the connecting rod 16 and the slider 15 to move inward, so that the slider once again actuates the protrusion 9 to rotate. The torsion spring 17 returns to its original state and also drives the protrusion 9 to rotate. This allows the protrusion 9 to rotate and drive the ball valve 7 to reverse and close, thereby achieving the effect of spraying cleaning fluid when the screen passes by, reducing waste. After the cleaning fluid is added, the car navigation screen is cleaned by the subsequent cleaning mechanism. After cleaning is completed, the car navigation screen can be removed.

[0027] Example 2: Based on Example 1, refer to Figure 5 and Figure 6 As shown, the cleaning mechanism includes a support base 1701, a second guide rod 18, a connecting plate 19, a second elastic element 20, and a sponge brush 21. The support base 1701 is fixedly connected to both the left and right sides of the center of the cleaning box 101. The second guide rod 18 is slidably arranged on the support base 1701. The connecting plate 19 is fixedly connected to the ends of the two second guide rods 18. The second elastic element 20 is sleeved on the second guide rod 18. The two ends of the second elastic element 20 are respectively connected to the support base 1701 and the connecting plate 19. The sponge brush 21 is rotatably arranged between the two connecting plates 19.

[0028] When the cleaning mechanism cleans the car navigation screen, the car navigation screen squeezes the sponge brush 21 upward, which in turn moves the two connecting plates 19 and the second guide rod 18 on itself upward. The second elastic element 20 is compressed and quickly rebounds, causing the two connecting plates 19, the two second guide rods 18, and the sponge brush 21 to move downward, making the sponge brush 21 in close contact with the car navigation screen. Under the action of the electric conveyor roller 2, the car navigation screen moves backward, squeezing the sponge brush 21 to rotate, thereby enabling the sponge brush 21 to automatically clean the car navigation screen and remove the cleaning fluid from it.

[0029] See Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, it also includes an air pipe 22, an air nozzle 23, a connecting pipe 24 and a connector 25. The air pipe 22 is symmetrically fixedly connected to the rear of the cleaning box 101. Two connecting pipes 24 are connected between the ends of the two air pipes 22. A connector 25 is provided on the connecting pipe 24. Multiple air nozzles 23 are evenly spaced on the air pipe 22.

[0030] See Figure 7 As shown, it also includes a fixing plate 26, an electric heating tube 27, a mounting bracket 28, and an exhaust fan 29. The mounting bracket 28 is installed on the top rear side of the cleaning box 101 by welding. Multiple exhaust fans 29 are evenly spaced on the mounting bracket 28 by bolt connection. The exhaust fans 29 are arranged in a 3×4 array. The fixing plates 26 are symmetrically fixed to the left and right sides of the rear part of the cleaning box 101. The electric heating tubes 27 are installed between the four fixing plates 26. The electric heating tubes 27 are located below the exhaust fans 29.

[0031] After cleaning, when the car navigation screen is moved below the electric heating element 27, the connector 25 is connected to the air pump, which draws in outside air into the connecting pipe 24 and delivers it into the air pipe 22, finally blowing it out from the air nozzle 23. At the same time, the exhaust fan 29 and the electric heating element 27 are activated, causing the electric heating element 27 to convert electrical energy into heat energy, and the exhaust fan 29 to draw in outside air, so that the outside air and the heat on the electric heating element 27 form hot air, which is blown onto the car navigation screen. This allows for multi-stage rapid drying of the car navigation screen, ensuring that there are no residues on the car navigation screen.

[0032] See Figure 1 and Figure 8 As shown, it also includes a water collection box 30, a water outlet pipe 31, and a recycling box 32. The water collection box 30 is fixedly connected to the base frame 1. The water collection box 30 is located below the electric conveyor roller 2. The water outlet pipe 31 is connected to the front bottom of the water collection box 30. The recycling box 32 is slidably installed on the base frame 1 and is located below the water collection box 30.

[0033] See Figure 1 and Figure 5 As shown, it also includes a protective net 33. The protective net 33 is fixedly connected to the rear of the cleaning box 101. The protective net 33 can prevent impurities from entering the cleaning box 101.

[0034] When cleaning is being done, the splashed cleaning fluid falls into the water collection box 30 and is collected into the recycling bin 32 through the water supply pipe 5 on the water collection box 30, thus facilitating collection and cleaning.
