When the car washer needs to be used, the round head of the limiting column 36 in the limiting hole 24 is pressed down by hand, so that the limiting column 36 contracts inwards along the sliding groove C33, and the spring B37 is compressed and stores energy; the cylindrical surface of the round head end of the limiting column 36 is separated from the limiting hole 24, under the action of the pre-pressed spring A38, the sliding block 32 tends to move upwards along the sliding cavity 21, the edge of the opening of the limiting hole 24 acts on the round head of the limiting column 36, so that the limiting column 36 further contracts along the sliding groove C33 and gradually releases the limitation on the sliding block 32, and the spring B37 is further compressed and stores energy; after the slide block 32 slides upwards for a certain distance along the slide cavity 21, the round end of the limiting column 36 is contacted with the inner wall of the slide cavity 21, and the spring B37 is compressed to the limit; in the process that the sliding block 32 slides upwards along the sliding cavity 21, the sliding block 32 drives the sliding sleeves 42 in the two recovery circulation mechanisms 39 to move upwards through the two swing pins B34 arranged on the two sides of the sliding block, the meshing points of the two gears C27 and the corresponding racks 40 gradually approach the sliding sleeves 42 along the circumferential direction of the gear C27, and the distances between the meshing points of the two gears C27 and the corresponding racks 40 and the corresponding swing pins B34 gradually decrease; under the action of the two gears C27, the two racks 40 in the two recycling mechanisms 39 drive the corresponding sliding sleeves 42 to respectively swing around the corresponding swing pins B34 at the same time, the two racks 40 drive the corresponding water blocking arc plates 47 to swing back to back around the corresponding swing pins B34, and the two volute spiral springs 55 are further compressed and store energy; meanwhile, the racks 40 in the two recycling mechanisms 39 slide in the corresponding sliding sleeves 42, the sliding sleeves 42 drive the rollers 46 to move obliquely upwards along the lower side surfaces of the racks 40 through the corresponding U-shaped seats 45, the rollers 46 roll and gradually separate from the corresponding hoses B52, and the rollers 46 gradually release the extrusion on the corresponding hoses B52; at this time, since the racks 40 of the two recovery circulation mechanisms 39 act on the two gears C27 in opposite directions and are balanced with each other, the rotation shaft 28 does not rotate, the gear B26 does not rotate, the gear a18 does not rotate, and the link block 13 and the handle 14 do not swing about the swing pin a19 with respect to the swing plate 20.

When the slide block 32 moves vertically upwards to the top of the slide cavity 21, the two swing pins B34 arranged at two sides of the slide block 32 stop moving synchronously with the slide block 32; the two sliding sleeves 42 and the corresponding racks 40 stop relative sliding and swing around the corresponding swing pins B34 simultaneously, and the meshing points of the racks 40 and the corresponding gears C27 are located at the lower limit positions; the rollers 46 in the two recovery circulation mechanisms 39 just release the compression of the corresponding hose B52; two hoses B52 in the two recovery circulation mechanisms 39 form a passage; then swinging the swing plate 20 to swing relative to the handle 14; the swinging plate 20 drives the spray pipe 29 and the spray nozzle 31 to move synchronously; then the swinging plate 20 is twisted to rotate relative to the handle 14, so that the nozzle 31 is aligned with the part of the surface of the vehicle body needing to be cleaned; in the process, the handle 14 is always kept to be basically vertical to the surface of the vehicle body to be cleaned; then the water pumping mechanism 1 is started, and a pump A10 and a pump B5 in the water pumping mechanism 1 run simultaneously; the pump A10 in the water pumping mechanism 1 pumps the water in the water tank 2 into the spray pipe 29 through the hard pipe A12 and the hose A54 and sprays out at high pressure through the nozzle 31, and the high-pressure water column sprayed out by the nozzle 31 cleans the surface of the vehicle body; the high-pressure water column sprayed from the nozzle 31 is reflected by the surface of the car body and then is sputtered into the water retaining arc plate 47 opposite to the spraying direction of the nozzle 31, and the water absorbing layer 50 arranged on the inner arc surface of the water retaining arc plate 47 absorbs the car washing wastewater sputtered onto the water retaining arc plate 47; under the pumping action of the pump B5, the wastewater absorbed in the water absorption layer 50 enters the filter 8 through the suction nozzles 49 and the thin hoses 51, and the wastewater is pumped into the water tank 2 for recycling after being continuously pumped by the pump B5 after being filtered by the filter 8; during the cleaning process, the swing angle of the swing plate 20 around the swing pin a19 relative to the handle 14 and the rotation angle of the swing plate 20 around the central axis of the handle 14 relative to the handle 14 can be changed according to the change of the cleaning position.

In the process that the swing plate 20 swings around the swing pin A19 relative to the handle 14, the gear B26 rotates under the action of the gear A18, and the gear B26 drives the two gears C27 to synchronously rotate through the rotating shaft 28; the two gears C27 respectively drive the racks 40 in the two recycling mechanisms 39 to slide relative to the sliding sleeves 42; the rack 40 in the recovery circulating mechanism 39 with the water retaining arc plates 47 facing the spraying direction of the nozzle 31 extends towards the surface of the vehicle body along the corresponding sliding sleeve 42, and the roller 46 in the recovery circulating mechanism 39 gradually gets away from the hose B52 which is linearly distributed on the lower side of the corresponding rack 40 along the length direction of the rack 40; the rack 40 in the other recovery circulation mechanism 39 performs contraction movement in a direction away from the vehicle body surface along the corresponding sliding sleeve 42, the roller 46 in the recovery circulation mechanism 39 starts to press the corresponding hose B52, and the passage of the hose B52 in the recovery circulation mechanism 39 is blocked; as the adjustment of the swing angle of the swing plate 20 about the swing pin a19 with respect to the handle 14 changes, the inclination angle of the ejection direction of the nozzle 31 with respect to the vehicle body surface changes; when the swing plate 20 swings around the swing pin A19 in a direction vertical to the surface of the vehicle body, the inclination angle of the spraying direction of the nozzle 31 relative to the surface of the vehicle body is increased, the inclination angle of the splashing direction of the high-pressure water column sprayed out of the nozzle 31 after being reflected by the surface of the vehicle body relative to the surface of the vehicle body is increased, and the rack 40 in the recovery circulating mechanism 39 where the water retaining arc plate 47 opposite to the spraying direction of the nozzle 31 is located drives the water retaining arc plate 47 to retract and capture waste water changed by the splashing angle; when the swing plate 20 swings around the swing pin A19 in a direction away from the direction vertical to the surface of the vehicle body, the inclination angle of the spraying direction of the nozzle 31 relative to the surface of the vehicle body is reduced, the inclination angle of the splashing direction of the high-pressure water column sprayed out of the nozzle 31 after being reflected by the surface of the vehicle body relative to the surface of the vehicle body is reduced, the rack 40 in the recovery circulating mechanism 39 where the water retaining arc plate 47 opposite to the spraying direction of the nozzle 31 is located drives the water retaining arc plate 47 to extend and capture waste water changed due to the sputtering angle, and the water sprayed out of the nozzle 31 at any angle can be captured, adsorbed and recovered by the water absorbing layer 50 on the water retaining arc plate 47 after being emitted by the surface of the vehicle body.

After the cleaning of the surface part of the vehicle body is finished, the swinging plate 20 can be twisted to rotate around the central axis of the handle 14 relative to the handle 14, the swinging plate 20 drives the spray pipe 29, the spray nozzle 31 and the two recovery circulating mechanisms 39 to synchronously rotate, and the spray nozzle 31 can clean the surface of the vehicle body around the handle 14 as the center; in order to effectively improve the cleaning efficiency, when the device is used for cleaning a part of the surface of the vehicle body, the swinging swing plate 20 swings around the swing pin B34 relative to the handle 14, and the swinging swing plate 20 drives the spray pipe 29 and the spray nozzle 31 to swing in the opposite direction of the original cleaning direction; during the swinging process of the swinging plate 20 in the opposite direction, the spraying direction of the nozzle 31 starts to turn to the water baffle 47 in the other recovery circulation mechanism 39; in the process, the water retaining arc plate 47 which originally recovers the wastewater retracts under the driving of the corresponding rack 40, and the water retaining arc plate 47 which originally does not recover the wastewater moves along with the extension of the corresponding rack 40 and captures the spraying direction of the nozzle 31 opposite to the rack; the roller 46 of the recycling mechanism 39, which was originally used for recycling the waste water, is rotated by the corresponding rack 40 and gradually approaches the corresponding hose B52 and gradually presses the hose B52, thereby blocking the passage of the corresponding hose B52; the roller 46 in the recycling mechanism 39, which is not used for recycling waste water originally, is driven by the corresponding rack 40 to rotate and gradually releases the extrusion on the corresponding hose B52, so that the hose B52 is restored to the passage again, the high-pressure water column sprayed out by the nozzle 31 is reflected by the surface of the vehicle body, then splashed onto the water retaining arc plate 47 in the recycling mechanism 39 and absorbed and recycled by the water absorbing layer 50 arranged on the row of the water retaining office, and the waste water absorbed in the water absorbing layer 50 is then pumped by the pump B5 and filtered by the filter 8 to enter the water tank 2, so that recycling is achieved.

During the swinging process of the swinging plate 20 relative to the handle 14 and the connecting block 13, the sliding sleeves 42 in the two recovery circulation mechanisms 39 do not move relative to the swinging plate 20, and the relative swinging between the sliding sleeves 42 and the swinging plate 20 around the swinging pins B34 does not occur; except that the gear A18 drives the racks 40 in the two recovery circulation mechanisms 39 to slide relative to the corresponding sliding sleeves 42 through a series of transmission, and the sliding states of the two racks 40 relative to the corresponding sliding sleeves 42 are opposite.

When the invention is used, the water pumping mechanism 1 is closed, the water pumping mechanism 1 stops running, and the water column is not sprayed in the nozzle 31; then swinging the swinging plate 20 back around the swinging pin A19 relative to the handle 14, so that the swinging plate 20 is restored to the relative initial state with the handle 14 and the connecting block 13; in the process that the swinging plate 20, the handle 14 and the connecting block 13 are restored to the relative initial state, the gear A18 drives the gear B26 to rotate towards the initial state; the gear B26 drives the two gears C27 to rotate towards the initial state through the rotating shaft 28; the two gears C27 simultaneously drive the two racks 40 in the two recycling mechanisms 39 to respectively slide along the corresponding sliding sleeves 42 to the relative initial state thereof relative to the sliding sleeves 42, and simultaneously, the two recycling mechanisms 39 synchronously swing back along with the swing plate 20; when the swing plate 20 swings back around the swing pin a19 to a state where the angle between the swing plate and the handle 14 is zero, the projections of the racks 40 in the two recovery circulation mechanisms 39 in the direction of the central axis of the swing pin are symmetrical about the vertical plane where the central axis of the swing pin a19 and the central axis of the swing pin B34 are located.

Then, the shift lever 35 is shifted downwards, and the shift lever 35 drives the slide block 32 to move downwards along the slide cavity 21; when the slider 32 moves to the initial position, the spring a38 is further compressed to the initial state; the limiting column 36 meets the limiting hole 24 right, under the reset action of the spring B37, the round end of the limiting column 36 instantly enters the limiting hole 24, the outer cylindrical surface of the limiting column 36 instantly contacts with the inner wall of the limiting hole 24, and the limiting column 36 again limits the sliding block 32; in the process of resetting the slide block 32, the slide block 32 drives the two recovery circulation mechanisms 39 to synchronously move through the two swing pins B34; under the reset action of the two scroll springs 55, the racks 40 in the two recovery circulation mechanisms 39 are always meshed with the two gears C27; under the action of the two gears C27, the two racks 40 respectively drive the corresponding sliding sleeves 42 to swing back around the corresponding swing pins B34 to the initial state; at the same time, the two racks 40 respectively slide relative to the corresponding sliding sleeves 42 and return to the initial state relative to the corresponding sliding sleeves 42.

In conclusion, the invention has the beneficial effects that: the two water retaining arc plates 47 work alternately, when the water spraying direction of the nozzle 31 swings to any one water retaining arc plate 47, the direction of a high-pressure water column sprayed out of the nozzle 31 moves to the concave arc surface of one water retaining arc plate 47 after being reflected by the surface of a vehicle body, and a water absorbing layer 50 arranged on the concave arc surface of the water retaining arc plate 47 absorbs waste water splashed on the water absorbing layer; the waste water adsorbed on the water absorption layer 50 is pumped by the pump B5, enters the filter 8 through the suction nozzle 49 for filtering, and is then sucked into the water tank 2 by the pump B5 for recycling; during the swinging process of the swinging plate 20 relative to the connecting block 13, the relative inclination angle of the spraying direction of the nozzle 31 and the surface of the vehicle body is changed; the nozzle 31 can clean the parts on the surface of the vehicle body, which are different distances away from an operator; when the inclination angle of the spraying direction of the nozzle 31 relative to the surface of the vehicle body is reduced, the high-pressure water flow sprayed by the nozzle 31 cleans the far position of the surface of the vehicle body, and in the swinging process of the swing plate 20, the rack 40 where the water retaining arc plate 47 opposite to the spraying direction of the nozzle 31 is located can rapidly move towards the water retaining arc plate 47 along the corresponding sliding sleeve 42; the water baffle arc plate 47 can block, recycle and adsorb the splashed waste water with smaller reflection inclination angle relative to the surface of the vehicle body; when the inclination angle of the spraying direction of the nozzle 31 relative to the surface of the vehicle body is increased, the high-pressure water flow sprayed by the nozzle 31 cleans the closer position of the surface of the vehicle body, and in the swinging process of the swing plate 20, the rack 40 where the water retaining arc plate 47 opposite to the spraying direction of the nozzle 31 is located can shrink along the corresponding sliding sleeve 42; the water baffle arc plate 47 can block, recycle and adsorb the splashed waste water with larger reflection inclination angle relative to the surface of the vehicle body; when one water retaining arc plate 47 recovers the wastewater, the other water retaining arc plate 47 is retracted and automatically blocks the hose B52 corresponding to the water retaining arc plate 47, so that all the power generated by the operation of the pump B5 is used for extracting the wastewater by the water retaining arc plate 47 for recovering the wastewater, and the efficiency of extracting the wastewater from the water retaining arc plate 47 for recovering the wastewater is improved; the invention effectively finishes the recycling and the cyclic utilization of the car washing wastewater in the process of cleaning the car body, greatly saves water resources, avoids water resource waste and has certain environmental protection benefit. After a part of the surface of the car body is cleaned, the whole car washing device does not need to rotate around the handle sleeve 16 to turn to the opposite part of the cleaned part on the surface of the car body, only the swinging swing plate 20 swings to the opposite position angle relative to the connecting block 13 or the handle 14, the water retaining arc plate 47 which is originally subjected to recovery work is retracted and the corresponding hose B52 is automatically cut off, the water retaining arc plate 47 which is not originally subjected to recovery work is extended and prepared to block, adsorb and recover waste water generated after the car body is washed by spraying water through the nozzle 31, so that the efficiency of cleaning the car body is improved, and physical power consumed by an operator due to repeated rotation of equipment is saved. In addition, the present invention can furl the two recycling mechanisms 39 when not in use, so that the space for storage is small, and the storage is convenient.
