Description

Technical Field

[0001] The present invention belongs to the field of intelligent car washing, and in particular relates to an intelligent car washing arm. Background Art

[0002] With the rapid development of my country's economy, the sales volume of automobiles in my country is increasing day by day. With the popularization of automobiles, more and more people are demanding car washing. Compared with traditional car washing methods, automatic car washing machines have many incomparable advantages. Automatic car washing machines are safe and reliable, fast and efficient, clean, environmentally friendly and water-saving, do not damage the paint surface, and save labor.

[0003] During the water transportation process, air will enter the pumping device, and the operation of the components in the pumping device will become asynchronous due to the change of the medium, the working capacity of the components will decrease, resulting in the unsmooth water transportation and reduced flow rate. Sometimes air plugs will form and interrupt the flow of water. In addition, impurities in the water will cause damage to the device and accelerate the aging of the device. Impurities will also clog the device and stop the water transportation. In addition, water is easy to flow into the device. Therefore, an intelligent car wash arm is proposed. Summary of the Invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract and title of this application to avoid obscuring the purpose of this section, the abstract and the title of the invention, and such simplifications or omissions should not be used to limit the scope of the present invention.

[0005] In view of the following technical problems in the existing technology: during the transportation of water, air will enter the pumping device, the operation of the components in the pumping device will be obstructed, and the working capacity of the components will decrease, thereby reducing the flow rate of water transportation, and sometimes forming air plugs to interrupt the flow of water; in addition, impurities in the water will cause damage to the device and accelerate the aging of the device, and impurities will also block the device and stop the water transportation; in addition, water is also easy to flow into the device.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an intelligent car washing arm, comprising a circular plate, on which several operating arms are screwed, and the operating arm is provided with a clamping plate and a motor 1 at one end away from the circular plate, and the power output end of the motor 1 is connected to a gear, and the rack passes through the space between the clamping plate and the gear, and the gear engages with one side of the rack; a connecting arm is provided at the bottom of the rack, and the connecting arm is fixedly connected to a hinge seat, and the hinge seat is hinged to a mounting plate, and several water spray strips are connected to the mounting plate, and a water channel is reserved in the water spray strip, and a nozzle is installed on the water spray strip, and the nozzle is connected to the water channel; the water channel of the nozzle is also connected to a liquid supply mechanism.

[0007] As an optimal technical solution for an intelligent car wash arm, the liquid supply mechanism includes an outer barrel 1, a motor 2, a circular piece, a rocking arm and a water storage barrel. The outer barrel 1 is installed on the water storage barrel, and the outer barrel 1 extends into the inner side of the water storage barrel. The water storage barrel is equipped with a motor 2, a circular piece and a rocking arm through a bracket. The power head of the motor 2 is equipped with a circular piece, and the circular piece is screwed onto the rocking arm. The rocking arm is hinged to a control rod, and the control rod is fixedly connected to the movable part 1.

[0008] The outer ring of the blocking bead is equipped with rubber, and the special-shaped cylinder is in the shape of 7.

[0009] As a preferred technical solution for an intelligent car wash arm, an intermediate tube is installed at the bottom of the outer barrel (1), with a flow hole (1) reserved on the intermediate tube. The intermediate tube extends into the outer barrel (2), with a screening hole reserved on the outer barrel (2). The space between the inner side of the outer barrel (2) and the intermediate tube serves as an operating chamber. The inner side of the outer barrel (1) is movably connected to the movable part (1), the interior space of which is provided with a sealing bead (1). The inner side of the outer barrel (1) is also provided with the movable part (2).

[0010] The movable part 2 is below the movable part 1, and the space between the movable parts 1 and 2 is the water chamber 1. The inner space of the outer barrel 1 located below the movable part 2 is the water chamber 2. The movable part 2 and the movable part 1 are both recessed with the same number of through holes of the same size. The inner space of the movable part 2 is provided with a sealing bead 2. The inner side of the movable part 2 reserves a channel 1. The channel 1 is divided into two upper and lower parts, wherein the size of the bottom part is larger than the size of the top part. The blocking bead is located at the bottom of the channel 1. The size of the blocking bead matches the size of the bottom of the channel 1 and is larger than the size of the top part of the channel 1. When the water pressure in the water chamber 1 is lower than the threshold, the blocking bead still keeps the channel 1 closed.

[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 installed on the inner side of channel one, and the bracket one is movably connected with a center column. The center column is connected to the bracket one through an elastic part, and the bottom of the center column is connected to the blocking bead. The center column can control 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 part two reaches water chamber two through 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 up and down, thereby performing a back-and-forth movement, so that the water passes through the screening hole on the outer barrel 2, the flow hole of the intermediate 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, thereby transporting the water to the water spray bar and spraying from the nozzle;

[0013] The moving part 1 moves upwards for the outward stroke, and the moving part moves downwards for the inward stroke. The water in the outward stroke passes through the screening hole of the outer barrel 2, and the water in the outward stroke stops reaching the inner space of the outer barrel 2 and the operating chamber, that is: during the inward stroke, the moving part 1 moves upwards, the sealing bead 1 seals the bottom of the moving part 1, the pressure in the water chamber 1 drops, and suction is generated; the sealing bead 2 moves upwards, and the water on the inner side of the water chamber 2 passes through the gap between the sealing bead 2 and the moving part 2 to reach the inner space of the moving part 2, and the water passes through the through hole of the moving part 2 to reach the water chamber 1. The water content in the water chamber 1 continues to increase. During this time, the movable part moves downward, and the water 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 on the inner side of the water chamber 1 increases, and the sealing bead 1 moves upward on the inner side of the movable part 1. The water 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, and the water passes through the through hole on the upper side of the movable part 1 and the top of the outer barrel 1. The water is pushed into the connecting cylinder when the movable part 1 moves upward next time. This back and forth motion is repeated, and impurities are blocked by the outer barrel 2 to prevent them 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 by connecting the cylinder and the outer barrel is as follows: a control rod is used to pull the movable part one out of the inner side of the outer barrel one, pushing the blocking bead downward, and the blocking bead carries the center column downward on the inner side of the channel one. The elastic part on the center column is stretched, and the blocking bead is separated from the movable part two, and the water on the upper side of the movable part two is able to pass through the channel one to the lower side of the movable part two and into the water chamber two, so that the water is discharged; the movable part one rotates back and forth, and the pressure on the inner side of the outer barrel one will not remain constant. The blocking bead blocks the bottom of the channel one, and the impact of the water chamber one stroke will cause the center column to move up and down. During this period, the blocking bead always blocks the channel one, so that the water chamber one and the water chamber two cannot communicate through the channel one.

[0015] The top of the movable member is provided with a movable bottom end, and the movable member is provided with a movable bottom end.

[0016] The three mounting frames use 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 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 form an air plug.

[0017] When the water is transported to the inner side 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, thus causing air embolism. The bubble removal mechanism can remove the air in the water chamber 1. Before the outward stroke, there is air in the water chamber 1. The air is mainly distributed above 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 hole on the circular disc and the through hole on the channel 1 and the movable part 1 make the circular disc not interfere with the normal flow of water, and the circular disc promotes Make the placement frame move upward with the movable part as the reference system, the placement frame and the movable part movably connected, the three placement frames use the movable seat to control the special-shaped pieces to approach each other, the special-shaped pieces abut the closing bead and move upward, forcing the closing bead and the movable part to be removed, so that the inner cavity of the device is filled to a degree that the closing bead will not lag and air embolism will not occur; the special-shaped piece is under the closing bead, and the air on the top of the placement frame reaches the movable part through the special-shaped cylinder of the special-shaped piece. The head of the placement frame is at the top of the inner side of the movable seat to constrain the placement frame, and the movable part will fall after continuing to end the stroke.

[0018] As an optimal technical solution for an intelligent car wash arm, it also includes an obstacle removal mechanism, which is placed inside the operating compartment. The obstacle removal mechanism includes a closed disc, which is movably connected to the outer barrel 2. The closed disc is plugged into the intermediate barrel. The closed disc is composed of two circular disc structures. The space between the intermediate barrel and the outer barrel 2 is such that the top size is larger than the bottom size. The tail of the closed disc is closed with the outer barrel 2. The operating compartment can accommodate water in the area between the filter hole and the closed disc. After 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 part 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. 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 and the outer barrel 2, and the closing disc moves downward. The water under the closing disc is sent to the inner side of the middle cylinder to fill the water loss caused by the blockage of the 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 disc is stretched, and suction is generated in the space above the closing disc. The first check member is opened, and the second check member is closed. The water reaches the closing disc through the through hole of the outer barrel 2. During the return stroke, the water presses the check piece 1 to close it, and the water presses the check piece 2 to open. 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 expansion of the water amount below the closed disk. The expanded water is discharged through the filter hole of the outer barrel 2. During this period, the filter hole is cleaned to remove some impurities, thereby eliminating blockage.

[0020] It also includes a debris removal mechanism, which is placed on the inner side of the middle tube. The debris removal mechanism includes a rotating column, which is screwed to the middle tube, passes through the outer barrel 2, and the outer barrel 2 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 the blade. The rotation of the blade causes 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 blade is lower than the edge part of the blade, so that the size of the outer circumference 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 drained away through channel one;

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

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

DETAILED DESCRIPTION

[0040] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0041] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0043] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, 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, the inner space of the movable part 15 is provided with a sealing bead 16, and the inner side of the outer barrel 12 is further provided with a movable part 2 17; 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 2 123. The movable part 17 and the movable part 1 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 2 18. The inner side of the movable part 17 is reserved for a channel 172. The channel 172 is divided into two upper and lower parts, wherein the size of the bottom part is larger than the size of the top part. The blocking bead 21 is 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 installed on the inside 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 part 2 17 reaches the water chamber 2 123 through 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 2 14 as downward and the movement away from the outer barrel 2 14 as upward. Set the end close to the outer barrel 2 14 as down and the end away from the outer barrel 2 14 as up:

[0049] The movable part 15 is connected to a control rod. The movable part 15 moves upward and downward, performing a back-and-forth motion, causing the liquid to pass through the screening hole on the outer barrel 2 14, the liquid flow hole in the intermediate cylinder 13, the water chamber 2 123, the interior space of the movable part 2 17, the through hole in the movable part 2 17, the water chamber 122, the interior space of the movable part 15, and the through hole in the movable part 15 to reach the connecting cylinder, thereby transporting the liquid to the water spray bar 10 and spraying from the nozzle 11.

[0050] The upward movement of movable part 15 is the outward movement, and the downward movement of movable part 15 is the inward movement. During the outward movement, the liquid passes through the screening hole of outer barrel 2 14. During the outward movement, the liquid stops reaching the inner space of outer barrel 2 14 and the operating chamber. That is, during the inward movement, movable part 15 moves upward, sealing bead 16 seals the bottom of movable part 15, and the pressure of water chamber 1 122 drops, generating suction and sucking in the liquid.

[0051] The pressure drop in water chamber 122 causes sealing bead 2 18 to move upward, and the water inside water chamber 2 123 passes through the gap between sealing bead 2 18 and movable part 2 17 to reach the interior space of movable part 2 17, and then passes through the through hole of movable part 2 17 to reach water chamber 122. The water content in water chamber 122 continues to increase.

[0052] During the forward stroke, the movable part 15 moves downward, and the water 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 on the inner side of the water chamber 122 increases, and the sealing bead 16 moves upward on the inner side of the movable part 15. The water 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, and the water passes through the through hole on the upper side of the movable part 15 and the top of the outer barrel 12. When the movable part 15 moves upward next time, the water is pushed into the connecting cylinder. This back and forth motion is repeated, and impurities are blocked by the screening hole of the outer barrel 2 14, preventing impurities from reaching the inner side of the device and interfering with the operation of the device.

[0053] The connecting tube and outer barrel 12 are drained by using a control rod to pull the movable part 15 out of the inner side of the outer barrel 12, pushing the blocking bead 21 downward. The blocking bead 21 carries the center column 20 downward along the inner side of the channel 172. The elastic member on the center column 20 is stretched, and the blocking bead 21 is separated from the movable part 2 17. The liquid on the upper side of the movable part 17 is able to pass through the channel 172 to the lower side of the movable part 17 and into the water chamber 2 123, thereby allowing the liquid to be drained.

[0054] As the movable part 15 rotates back and forth, 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 center column 20 to move up and down. During this period, the blocking bead 21 always blocks the channel 172, preventing the water chamber 122 and the water chamber 2 123 from communicating through the channel 172.

[0055] The apparatus further includes a debubble removal mechanism for removing air from the water chamber 122. The debubble removal mechanism is located inside the water chamber 122 and includes a mounting frame 222. The mounting frame 222 is movably connected to the bottom of the movable member 15. The mounting frame 222 is fixedly connected to a circular disk 224. The circular disk 224 is located in the water chamber 122 and has recessed through holes. The size and number of the through holes in the circular disk 224 are consistent with the through holes in the movable member 15.

[0056] During the transportation of the water, the circular disc 224 does not hinder the flow rate and flow rate of the water. 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 the movable seat 225. The movable seat 225 is recessed with a movable pit. 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. The head of the placement frame 222 is provided with a horizontal rod constrained by the movable pit. The movable seat 225 is fixedly connected to the special-shaped piece 226. The lower edge of the special-shaped piece 226 abuts against the lower edge of the inner side of the movable part 15. The circumference of the special-shaped piece 226 is recessed with a special-shaped cylinder 2262.

[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 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 will not form an air plug.

[0058] When the water is transported to the inner side of the device, air will also enter. The air occupies the space in the cavity of the device, making the response of the sealing bead 16 and the sealing bead 2 18 slow, thereby causing air embolism. The bubble removal mechanism can remove the air in the water chamber 122. Before the outward stroke, there is air in the water chamber 122, and the air is mainly distributed above 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 outward stroke, the circular disc 224 is in the water, and the movement of the circular disc 224 is slowed down. The through hole and the channel on the circular disc 224 The through holes on the bracket 17 and the movable part 15 prevent the circular disc 224 from interfering with the normal flow of water. The circular disc 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 connected to the movable part 15.

[0059] The special-shaped piece 226 is under the closing bead 16, and the air on the top of the mounting frame 222 reaches the space inside the movable part 15 by means of 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 incoming stroke, that is, the air under the movable part 15 can be compressed, causing the movable part 15 to move downward relative to the circular disk 224 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. 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] The device also includes an obstacle-clearing mechanism, which is placed inside the operating compartment and includes a closing disc 232, which is movably connected to the outer barrel 14 and plugged into the intermediate barrel 13. The closing disc 232 is composed of two circular disc structures.

[0061] The space between the middle cylinder 13 and the outer barrel 2 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 2 14. The area between the filter hole and the closing disk 232 of the operation chamber can accommodate water. When impurities block the filter hole on the outer barrel 2 14, 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 2 14 can be replenished. The closing disk 232 is closed with the outer barrel 2 An elastic part is installed between 14, the closing disk 232 is above the liquid flow hole of the middle tube 13 and the filtering hole of the outer barrel 2 14, the outer barrel 2 14 is milled with a through hole, the outer barrel 2 14 also reserves a liquid suction hole to facilitate the movement of the closing disk 232, and a filter plate and a check piece 233 are installed on the inner side of the liquid suction hole of the outer barrel 2 14, the check piece 1 233 is under the filter plate, a through hole is recessed on the closing disk 232, and a check piece 234 is installed on the through hole of the closing disk 232.

[0062] The obstacle removal mechanism can force the impurities on the filter hole to fall. 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 intermediate cylinder 13 and the outer barrel 2 14, and the closing disk 232 moves downward. The water below the closing disk 232 is sent to the inner side of the intermediate cylinder 13 to fill the water loss caused by the obstruction of the screening hole of the outer barrel 2 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 member 1 233 is opened, and the check member 2 234 is closed. The water reaches the closing disk 23 through the through hole of the outer barrel 2 14. 2. During the return stroke, the liquid presses the check piece 1 233 to close it, and the liquid presses the check piece 234 to open it. The liquid 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 liquid above the closing disk 232 is used to fill the gap, there is still some liquid left because the volume of the bottom of the space between the intermediate cylinder 13 and the outer barrel 2 14 is larger than the volume of the top, resulting in an increase in the amount of water below the closing disk 232. The increased water is discharged through the filter hole of the outer barrel 2 14. During this process, the filter hole is cleaned to remove some impurities, thereby eliminating the blockage.

[0063] The utility model further includes a debris removal mechanism, which is arranged on the inner side of the intermediate cylinder 13. The debris removal mechanism includes a rotating column 242, which is screwed to the intermediate cylinder 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 circumference 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, 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 blade 244 is lower than the edge part of the blade 244, so that the size of the outer circumference 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 continues to reach the inner side of the device to fill the inner side of the device with more water. The water reaches the inner side of the intermediate tube 13 through the flow hole of the intermediate tube 13, and 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] It also includes a cleaning mechanism, which can remove impurities on the periphery of the outer barrel 2 14. The cleaning mechanism is placed on the rotating column 242. The cleaning mechanism includes an outer ring 252 at the bottom of the outer barrel 2 14. The outer ring 252 is connected to the rotating column 242. The circumferential surface of the rotating column 242 is provided with a special-shaped cleaning piece 253. The cleaning piece 253 is frictionally connected to the periphery of the outer barrel 2 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 2 14.

[0066] It also includes a rejection mechanism, which can reject impurities on the periphery of the outer barrel 14. The rejection mechanism is configured 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. 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 outer 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. A dredging mechanism is configured on the threaded rod 262.

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

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

[0069] The cleaning mechanism and the rejection mechanism cooperate to remove the outer periphery of the outer barrel 2 14. The rotating column 242 uses the outer ring 252 to drive the special-shaped cleaning piece 253 to remove impurities on the periphery of the rotating column 14 of the outer barrel 2. 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 rejection platform 267 to move, thereby realizing the rejection of the outer barrel 2 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] The inner circumference of the rejecting platform 267 is provided with bristles, the length of which is 1.5 times the thickness of the special-shaped cleaning piece 253, and the special-shaped cleaning piece 253 can pass through the bristles laterally.

[0071] The specific implementation method is as follows: Motor 2 27 controls the rotation of the circular piece 28, and the circular piece 28 drives the control rod to move back and forth through the rocking arm 29. The control rod carries 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 and reaches the water spray bar 10, and the water flow is ejected from the nozzle 11 to wash away 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 embodiment, 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, for those of ordinary skill having the benefit of this disclosure, be a routine undertaking of design, fabrication, and production without undue experimentation.
