[0011] The blocking bead moves downward, and within a certain range, the blocking bead always closes channel one and cuts off the connection between channel one, water chamber one and water chamber two. A bracket one is arranged on the inner side of channel one, and a center column is movably inserted in the bracket one. The center column is connected to the bracket one through an elastic member, and the bottom of the center column is connected to the blocking bead. The center column can manipulate the blocking bead to move downward and out of channel one, so that water chamber one and water chamber two are connected, and the water located on the movable member two reaches water chamber two via channel one, so that the water flows out.

[0012] The movable part 1 is connected to a control rod, and the movable part 1 moves upward and downward to make a back-and-forth movement, so that the water passes through the screening hole on the outer barrel 2, the flow hole of the middle cylinder, the water chamber 2, the inner space of the movable part 2, the through hole of the movable part 2, the water chamber 1, the inner space of the movable part 1, and the through hole on the movable part 1 to reach the connecting cylinder, so that the water is transported to the water spray bar and sprayed from the nozzle;

The water content in the water chamber 1 continues to increase, and during the outward stroke, the moving part 1 moves upward, and the water in the water chamber 1 passes through the through hole of the moving part 2 to reach the inner space of the moving part 2. During this time, the movable part moves downward, the liquid squeezes the sealing bead 2 to abut against the wall below the movable part 2, so that the movable part 2 is sealed, the pressure inside the water chamber 1 increases, the sealing bead 1 moves upward on the inner side of the movable part 1, the liquid in the water chamber 1 passes through the gap between the sealing bead 1 and the movable part 1 to reach the inner side of the movable part 1, the liquid passes through the through hole on the upper side of the movable part 1 and the top of the outer barrel 1, and the liquid is pushed into the connecting cylinder when the movable part 1 moves upward next time, and this back and forth motion is repeated, and the impurities are blocked by the outer barrel 2 to prevent the impurities from reaching the inner side of the device and interfering with the operation of the device.

[0014] As an optimal technical solution for an intelligent car wash arm, a method for draining liquid from a connecting tube and an outer barrel is provided: a control rod is used to pull the movable part one out of the inner side of the outer barrel one, and the blocking beads are pushed downward.

The blocking beads close the bottom of the channel one, and the impact of the stroke of the water chamber one causes the central column to move up and down. During this period, the blocking beads always close the channel one, so that the water chamber one and the water chamber two cannot communicate through the channel one.

[0015] As an optimal technical solution for an intelligent car washing arm, it also includes a bubble removal mechanism for removing air from a water chamber, the bubble removal mechanism is located on the inner side of the water chamber, the bubble removal mechanism includes a mounting frame, the mounting frame is movably connected to the lower side of the movable member, the mounting frame is fixedly connected to a circular plate, the circular plate is located in the water chamber, and a through hole is also concavely arranged on the circular plate, the size and number of the through holes of the circular plate are consistent with the through holes of the movable member; during the transportation of the water liquid, the circular plate does not constitute an obstacle to the flow rate and flow velocity of the water liquid, a square hole is reserved on the movable member, the square hole does not connect the inside and the outside, the square hole of the movable member is movably connected to a movable seat, a movable pit is concavely arranged on the movable seat, the movable pit is movably connected to the head of the mounting frame, the head of the mounting frame is located on the upper side of the movable seat, the mounting frame is constrained by the movable pit, the movable seat is fixedly connected to a special-shaped sheet, the lower side of the special-shaped sheet abuts against the lower side of the inner side of the movable member, and a special-shaped cylinder is concavely arranged on the circumference of the special-shaped sheet;

[0016] 3. The mounting frame utilizes the movable seat to drive the special-shaped piece to approach, and the special-shaped piece abuts against the sealing bead and moves upward, forcing the sealing of the sealing bead and the movable part to be removed, so that the inner cavity of the device is filled to a certain extent, so that the sealing bead will not lag and will not form an air plug.

[0017] When the water is transported to the inside of the device, air will also enter. The air occupies the space in the cavity of the device, making the response of the sealing beads 1 and 2 slow down, thus causing air embolism. The bubble removal mechanism can remove the air in the water chamber 1. Before the outward stroke, the water chamber 1 retains air, and the air is mainly distributed on the upper side of the water chamber 1. During the downward movement of the movable part, the sealing bead 1 squeezes the gas and moves downward with the movable part 1. During the outward stroke, the circular disc is in the water, and the movement of the circular disc is slowed down. The through holes on the circular disc, the channel 1 and the through holes on the movable part 1 make the circular disc not interfere with the normal flow of the water, and the circular disc promotes Make the placement frame one move upward with the movable part one as the reference system, the placement frame one and the movable part one are movably plugged, the three placement frames one use the movable seat one to control the special-shaped sheets to approach each other, the special-shaped sheets abut against the closing beads one to move upward, forcing the closing of the closing beads one and the movable part one to be removed, so that the inner cavity of the device is filled to a degree that the closing beads one will not lag and air plugs will not occur; the special-shaped sheets are under the closing beads one, and the air on the top of the placement frame one uses the special-shaped cylinder of the special-shaped sheets to reach the movable part one, and the head of the placement frame one is at the top of the inner side of the movable seat one to constrain the placement frame one, and the movable part one will fall after a period of time to end the coming stroke.

[0018] As an optimal technical solution for an intelligent car washing arm, it also includes an obstacle clearing mechanism, which is arranged on the inner side of the operation chamber, and includes a closed disc, which is movably connected to the outer barrel 2, and the closed disc is plugged into the intermediate barrel, and the closed disc is composed of two circular disc structures, and the space between the intermediate barrel and the outer barrel 2 is such that the size of the top is larger than the size of the bottom, and the tail of the closed disc is closed with the outer barrel 2, and the area between the filter hole and the closed disc in the operation chamber can accommodate water, and after the impurities block the filter hole on the outer barrel 2, the bottom of the closed disc The water will enter the inner side of the middle cylinder, so that the water loss caused by the obstruction of the flow of the filter hole in the outer barrel 2 can be supplemented. An elastic member is arranged between the closing disk and the outer barrel 2. The closing disk is above the flow hole of the middle cylinder and the filter hole of the outer barrel 2. A through hole is milled on the outer barrel 2. The outer barrel 2 also reserves a liquid suction hole to facilitate the movement of the closing disk. A filter plate and a check piece 1 are arranged on the inner side of the liquid suction hole of the outer barrel 2. The check piece 1 is under the filter plate. A through hole is recessed on the closing disk, and a check piece 2 is arranged on the through hole of the closing disk.

[0019] The obstacle removal mechanism can force the impurities on the filter hole to fall off. After the impurities block the filter hole, the flow of water is blocked. During the outward stroke, suction is generated in the space between the middle tube and the outer barrel 2, and the closing plate moves downward. The water under the closing plate is sent to the inner side of the middle tube to fill the water loss caused by the blocked screening hole of the outer barrel 2, so as to ensure that the amount of transported water remains stable. During this period, the elastic member on the closing plate is stretched, and suction is generated in the space above the closing plate. The check piece 1 is opened, and the check piece 2 is closed. The water reaches the closing plate through the through hole of the outer barrel 2. During the coming stroke, the water presses the check piece 1 to close it, and the water presses the check piece 2 to open it. The water in the space above the closed disk is removed from the through hole of the closed disk and reaches the space below the closed disk. Even if the water above the closed disk is used to fill the gap, there is still some water left, because the bottom volume of the space between the middle cylinder and the outer barrel 2 is larger than the top volume, resulting in the amount of water below the closed disk being expanded. The expanded water is discharged through the filter hole of the outer barrel 2. During the process, the filter hole is cleaned to remove some impurities, thereby eliminating the blockage.

[0020] It also includes a debris removal mechanism, which is arranged on the inner side of the middle tube. The debris removal mechanism includes a rotating column, which is screwed to the middle tube, and passes through the outer barrel 2, which is screwed to the rotating column. The rotating column is fixedly connected to the hollow column, and the circumferential surface of the rotating column is fixedly connected to blades. The rotation of the blades allows the gas phase to merge into the liquid phase, thereby reducing the volume of free air. During this period, the air pressure is reduced, allowing more water to enter the device. The inner circle height of the blades is lower than the edge of the blades, so that the size of the outer circumferential surface can be increased.

[0021] The beneficial effects of the intelligent car washing arm of the present invention are as follows: by moving the blocking beads out of channel one, the water above the blocking beads is discharged through channel one;

[0022] The closing plate moves downward, allowing the water on the upper side of the closing plate to flow down from the through hole. During this process, the water filter hole is flushed and cleaned to remove some impurities, thereby eliminating blockage and extending the maintenance period.

[0023] The movable seat 1 is used to drive the special-shaped sheet to approach, and the special-shaped sheet abuts against the sealing bead 1 and moves upward, forcing the sealing of the sealing bead 1 and the movable member 1 to be removed, so that the inner cavity of the device is filled to a degree that the sealing bead 1 will not lag and will not form an air plug;

[0024] Special-shaped cleaning parts and rejection mechanisms. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0044] like Figures 1 to 12As shown, the present invention proposes an intelligent car washing arm, wherein an intermediate cylinder 13 is arranged at the bottom of the outer barrel 12, a flow hole 1 is reserved on the intermediate cylinder 13, the intermediate cylinder 13 extends into the outer barrel 2 14, a screening hole is reserved on the outer barrel 2 14, the space between the inner side of the outer barrel 2 14 and the intermediate cylinder 13 is an operation chamber, the inner side of the outer barrel 12 is variably connected to a movable part 15, a sealing bead 16 is arranged in the inner space of the movable part 15, and a movable part 2 17 is also arranged on the inner side of the outer barrel 12; the movable part 2 17 is below the movable part 15, the space between the movable part 15 and the movable part 2 17 is a water chamber 122, and the inner space of the outer barrel 12 is located at The part below the movable part 17 is the water chamber 123. The movable part 17 and the movable part 15 are both recessed with the same number of through holes of the same size. The inner space of the movable part 17 is provided with a closing bead 18. The inner side of the movable part 17 reserves a channel 172. The channel 172 is divided into two upper and lower parts, wherein the size of the bottom part is larger than that of the top part. The blocking bead 21 is located at the bottom of the channel 172. The size of the blocking bead 21 matches the size of the bottom of the channel 172 and is larger than the size of the top part of the channel 172. When the water pressure in the water chamber 122 is lower than the threshold value, the blocking bead 21 still keeps the channel 172 closed.

[0045] The water flows through and drives the hollow column 243 to rotate.

[0046] The blocking bead 21 moves downward, and within a certain range, the blocking bead 21 always closes the channel 172, cutting off the connection between the channel 172 and the water chamber 122 and the water chamber 2 123. A bracket 19 is arranged on the inner side of the channel 172, and the bracket 19 is movably connected with a center column 20. The center column 20 is connected to the bracket 19 through an elastic member, and the lower side of the center column 20 is connected to the blocking bead 21. The center column 20 can manipulate the blocking bead 21 to move downward and out of the channel 17, so that the water chamber 122 and the water chamber 2 123 are connected, and the water located on the movable member 2 17 reaches the water chamber 2 123 via the channel 172, so that the water flows out.

[0047] The elastic member includes a spring.

[0048] Set the movement close to the outer barrel 14 as downward and falling, and the movement away from the outer barrel 14 as upward. Set the end close to the outer barrel 14 as down, and the end away from the outer barrel 14 as up:

[0049] The movable part 15 is connected to a control rod, and the movable part 15 moves upward and downward to make a back-and-forth movement, so that the water passes through the screening hole on the outer barrel 2 14, the flow hole of the middle cylinder 13, the water chamber 2 123, the inner space of the movable part 2 17, the through hole of the movable part 2 17, the water chamber 1 122, the inner space of the movable part 15, and the through hole on the movable part 15 to reach the connecting cylinder, so that the water is transported to the water spray bar 10 and sprayed from the spray head 11;

[0050] The upward movement of the movable part 15 is the outward movement, and the downward movement of the movable part 15 is the inward movement. The water in the outward movement passes through the screening hole of the outer barrel 2 14, and the water in the outward movement stops reaching the inner space and the operation chamber of the outer barrel 2 14, that is, during the inward movement, the movable part 15 moves upward, the sealing bead 16 seals the bottom of the movable part 15, and the pressure of the water chamber 122 decreases, generating suction to absorb the water;

[0051] The pressure drop in the water chamber 122 causes the sealing bead 18 to move upward, and the water in the water chamber 123 passes through the gap between the sealing bead 18 and the movable part 17 to reach the inner space of the movable part 17, and then passes through the through hole of the movable part 17 to reach the water chamber 122. The water content in the water chamber 122 continues to increase.

[0052] During the forward stroke, the movable part 15 moves downward, the liquid squeezes the sealing bead 18 to abut against the wall below the movable part 17, so that the movable part 17 is sealed, the pressure inside the water chamber 122 increases, the sealing bead 16 moves upward on the inner side of the movable part 15, the liquid in the water chamber 122 passes through the gap between the sealing bead 16 and the movable part 15 to reach the inner side of the movable part 15, the liquid passes through the through hole on the upper side of the movable part 15 and the top of the outer barrel 12, and the liquid is pushed into the connecting cylinder when the movable part 15 moves upward next time, and this back and forth motion is repeated, and the impurities are blocked by the screening hole of the outer barrel 14 to prevent the impurities from reaching the inner side of the device and interfering with the operation of the device.

[0053] The method of draining liquid from the connecting cylinder and the outer barrel 12 is as follows: the movable part 15 is pulled out of the inner side of the outer barrel 12 by using the control rod, and the blocking bead 21 is pushed downward, and the blocking bead 21 brings the central column 20 downward in the inner side of the channel 172, and the elastic part on the central column 20 is stretched, and the blocking bead 21 is separated from the movable part 2 17, and the liquid on the movable part 2 17 can pass through the channel 172 to the lower side of the movable part 2 17 and the water chamber 2 123, so that the liquid can be discharged;

[0054] The movable part 15 rotates back and forth, and the pressure inside the outer barrel 12 will not remain constant. The blocking bead 21 blocks the bottom of the channel 172. The impact of the water chamber 122's stroke will cause the central column 20 to move up and down. During this period, the blocking bead 21 always blocks the channel 172, so that the water chamber 122 and the water chamber 2 123 cannot communicate through the channel 172.

[0055] It also includes a degassing mechanism for removing air from the water chamber 122, the degassing mechanism is located inside the water chamber 122, the degassing mechanism includes a mounting frame 222, the mounting frame 222 is movably connected to the bottom of the movable part 15, the mounting frame 222 is fixedly connected to a circular plate 224, the circular plate 224 is located in the water chamber 122, and the circular plate 224 is also concavely provided with through holes, and the size and number of the through holes of the circular plate 224 are consistent with the through holes of the movable part 15;

[0056] During the transportation of the water liquid, the circular disc 224 does not hinder the flow rate and flow rate of the water liquid. A square hole is reserved on the movable part 15, and the square hole is not connected to the inside and outside. The square hole of the movable part 15 is movably connected to a movable seat 225, and a movable pit is concavely arranged on the movable seat 225. The movable pit is movably connected to the head of the placement frame 222. The head of the placement frame 222 is located above the movable seat 225. A horizontal rod is arranged on the head of the placement frame 222 and is constrained by the movable pit. The movable seat 225 is fixedly connected to a special-shaped piece 226. The lower side of the special-shaped piece 226 abuts against the lower side of the inner side of the movable part 15, and a special-shaped cylinder 2262 is concavely arranged on the circumference of the special-shaped piece 226.

[0057] The three mounting frames 222 use the movable seat 225 to drive the special-shaped piece 226 to approach, and the special-shaped piece 226 abuts against the sealing bead 16 and moves upward, forcing the sealing bead 16 and the movable member 15 to be removed, so that the inner cavity of the device is filled to a certain extent, so that the sealing bead 16 will not lag and will not form an air plug.

[0058] When the water is transported to the inner side of the device, air will also enter, and the air will occupy the space in the inner cavity of the device, making the response of the sealing bead 16 and the sealing bead 2 18 slow down, thereby causing air embolism. The bubble removal mechanism can remove the air in the water chamber 122. Before the outward stroke, the water chamber 122 retains air, and the air is mainly distributed on the upper side of the water chamber 122. During the downward movement of the movable part 15, the weight of the sealing bead 1 can squeeze the gas and move downward with the movable part 15. During the inward stroke, the circular disk 224 is in the water, and the movement of the circular disk 224 is slowed down. The through hole and the channel on the circular disk 224 The through holes on 17 and the movable part 15 make the circular disk 224 not interfere with the normal flow of water. The circular disk 224 prompts the placement frame 222 to move upward with the movable part 15 as the reference system. The three placement frames 222 use the movable seat 225 to control the special-shaped pieces 226 to approach each other. The inner inclined surface of the special-shaped piece 226 abuts against the sealing bead 16 to force the sealing bead 16 to move upward, forcing the sealing bead 16 and the movable part 15 to be removed, so that the inner cavity of the device is filled to a certain extent, so that the sealing bead 16 will not lag and air embolism will not occur; the placement frame 222 is movably plugged into the movable part 15.

[0059] The special-shaped piece 226 is under the closing bead 16, and the air at the top of the mounting frame 222 reaches the inner space of the movable part 15 through the special-shaped cylinder 2262 of the special-shaped piece 226. The head of the mounting frame 222 is at the top of the inner side of the movable seat 225, constraining the mounting frame 222. The movable part 15 will fall after a period of time to end the coming stroke, that is, the air under the movable part 15 can be compressed, causing the movable part 15 and the circular disk 224 to move downward relatively without synchronization, and the mounting frame 222 squeezes the movable seat 225, so that the movable seat 225 forces the closing bead 16 to move upward, and a gap is generated between the closing bead 16 and the bottom of the movable part 15, and the gap is connected to the special-shaped cylinder 2262, and the gas enters the movable part 15 through the special-shaped cylinder 2262.

[0060] It also includes an obstacle-clearing mechanism, which is arranged on the inner side of the operation compartment. The obstacle-clearing mechanism includes a closing disk 232, which is movably connected in the outer barrel 14, and the closing disk 232 is plugged into the middle barrel 13. The closing disk 232 is composed of two circular disk structures;

[0061] The space between the middle cylinder 13 and the outer barrel 14 is such that the size of the top is larger than the size of the bottom. The tail of the closing disk 232 is closed with the outer barrel 14. The area between the filter hole and the closing disk 232 of the operation chamber can accommodate water. After the filter hole on the outer barrel 14 is blocked by impurities, the water under the closing disk 232 will enter the inner side of the middle cylinder 13, so that the water loss caused by the obstruction of the flow of the filter hole in the outer barrel 14 can be supplemented. The closing disk 232 is closed with the outer barrel 14. An elastic member is arranged between the middle tube 13 and the outer barrel 14, the closing disk 232 is above the liquid flow hole of the middle tube 13 and the filtering hole of the outer barrel 14, the outer barrel 14 is milled with a through hole, the outer barrel 14 also reserves a liquid suction hole to facilitate the movement of the closing disk 232, a filter plate and a check piece 233 are arranged on the inner side of the liquid suction hole of the outer barrel 14, the check piece 233 is under the filter plate, a through hole is recessed on the closing disk 232, and a check piece 234 is arranged on the through hole of the closing disk 232.

[0062] The obstacle removal mechanism can force the impurities on the filter hole to fall off. After the impurities block the filter hole, the flow of water is blocked. During the outward stroke, suction is generated in the space between the middle cylinder 13 and the outer barrel 14, and the closing disk 232 moves downward. The water below the closing disk 232 is sent to the inner side of the middle cylinder 13 to fill the water loss caused by the blocked screening hole of the outer barrel 14, so as to ensure that the amount of transported water remains stable. During this period, the elastic member on the closing disk 232 is stretched, and suction is generated in the space above the closing disk 232. The check piece 1 233 is opened, and the check piece 234 is in a closed state. The water reaches the closing disk 23 through the through hole of the outer barrel 14. 2, during the execution of the coming stroke, the water presses the check piece 1 233 to close it, and the water presses the check piece 234 to open, and the water in the space above the closing disk 232 is removed from the through hole of the closing disk 232 and reaches the space below the closing disk 232. Even if the water above the closing disk 232 is used to fill the vacancy, there is still some water left, because the bottom volume of the space between the middle cylinder 13 and the outer barrel 2 14 is larger than the top volume, resulting in the amount of water below the closing disk 232 being expanded. The expanded water is discharged through the filtering hole of the outer barrel 2 14. During the process, the filtering hole is cleaned to remove some impurities, thereby eliminating the blockage.

[0063] The device also includes a debris removal mechanism, which is arranged on the inner side of the middle tube 13. The debris removal mechanism includes a rotating column 242, which is screwed to the middle tube 13, and passes through the outer barrel 14. The outer barrel 14 is screwed to the rotating column 242. The rotating column 242 is fixedly connected to the hollow column 243. The circumferential surface of the rotating column 242 is fixedly connected to the blade 244. The blade 244 rotates to make the gas phase merge into the liquid phase, so that the volume of free air is reduced. During this period, the air pressure is reduced, so that more water can enter the device. The inner circle height of the blade 244 is lower than the edge part of the blade 244, so that the size of the outer circumferential surface can be increased.

[0064] The impurity removal mechanism is driven by the water during the transportation of the water, and the hollow column 243 rotates. The hollow column 243 uses the rotating column 242 to drive the blade 244 to rotate. The blade 244 pumps air into the water, and the water can continue to reach the inner side of the device so that more water fills the inner side of the device. The water reaches the inner side of the intermediate tube 13 through the flow hole of the intermediate tube 13. The water gathers at the center and goes upward. The rotating surface of the blade 244 is 90 degrees to the flow direction of the water.

[0065] The utility model also includes a cleaning mechanism, which can remove impurities on the periphery of the outer barrel 14. The cleaning mechanism is arranged on a rotating column 242. The cleaning mechanism includes an outer ring 252 at the lower side of the outer barrel 14. The outer ring 252 is connected to the rotating column 242. A special-shaped cleaning piece 253 is arranged on the peripheral surface of the rotating column 242. The cleaning piece 253 is frictionally connected with the periphery of the outer barrel 14. The rotating column 242 uses the outer ring 252 to drive the special-shaped cleaning piece 253 to remove impurities attached to the outside of the outer barrel 14.

[0066] It also includes a rejection mechanism, which can reject impurities on the periphery of the outer barrel 14. The rejection mechanism is arranged on the rotating column 242. The rejection mechanism includes a threaded rod 262, which is fixedly connected to the rotating column 242. A restraining member 263 is installed on the outer barrel 14. The restraining member 263 is movably connected to the movable seat 264, and the movable seat 264 is threaded with the threaded rod 262. The restraining member 263 guides the movement of the movable seat 264. The movable seat 264 is screwed to the rotating ring 265. The periphery of the rotating ring 265 is fixedly connected to the special-shaped frame 266. The special-shaped frame 266 is L-shaped. The special-shaped frame 266 is fixedly connected to the rejection platform 267. The rejection platform 267 is movably connected to the special-shaped cleaning member 253. The rejection platform 267 can reject impurities on the periphery of the outer barrel 14. The threaded rod 262 is arranged with a dredging mechanism.

[0067] Two thread grooves with the same pitch and opposite rotation directions are reserved on the threaded rod 262, and the two ends are connected by a transition curve.

[0068] The unblocking mechanism can prevent the movable seat 264 from being blocked. The unblocking mechanism includes a sealing piece 268 . The sealing piece 268 is fixedly connected to the threaded rod 262 . The movable seat 264 is screwed to the elastic cylinder 269 , and the elastic cylinder 269 and the outer ring 252 are fixedly connected.

[0069] The cleaning mechanism and the rejecting mechanism cooperate to reject the outer periphery of the outer barrel 14. The rotating column 242 uses the outer ring 252 to drive the special-shaped cleaning piece 253 to remove impurities on the outer periphery of the rotating column 14 of the outer barrel. The rotating column 242 drives the threaded rod 262 to rotate. The restraining effect of the restraining piece 263 causes the threaded rod 262 to pull the movable seat 264 to move. The movable seat 264 uses the rotating ring 265 and the special-shaped frame 266 to drive the rejecting platform 267 to move, thereby realizing the rejection of the outer barrel 14 in both axial and circumferential directions, eliminating blockage, and preventing excessive impurities from entering the device and causing damage, thereby extending the normal working cycle length of the device. The dredging mechanism can prevent the threaded rod 262 from being eroded by impurities, so that the movable seat 264 can work normally.

[0070] Brushes are arranged on the inner circumference of the rejecting platform 267, and the length of the brushes is 1.5 times the thickness of the special-shaped cleaning piece 253, and the special-shaped cleaning piece 253 can pass through the brushes horizontally.

[0071] The specific implementation method is as follows: Motor 2 27 controls the circular piece 28 to rotate, and the circular piece 28 drives the control rod to move back and forth through the rocking arm 29. The control rod drives the movable part 15 to move back and forth in the outer barrel 12. When the movable part 15 moves close to the outer barrel 2 14, the water pushes 16 into the movable part 15 and reaches the side of the movable part 15 close to the control rod. When the movable part 15 moves away from the outer barrel 2 14, the water is squeezed by the movable part 15 to reach the water spray bar 10, and the water flow is ejected from the nozzle 11, and the water flow washes the dust on the surface of the vehicle.

[0072] The first check member 233 and the second check member 234 are both check valves.

[0073] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.
