Description

Technical Field

[0001] The invention belongs to the technical field of mobile car washing, and in particular relates to a micro-water movable car washing device. Background Art

[0002] With the continuous improvement of people's living standards, cars as a means of transportation are more and more widely used in people's daily lives. Car washing equipment is a type of equipment used to rinse and clean dirt, mud and other impurities adhered to the outer surface of the car. Common car washing equipment can be divided into several types according to different principles: high-pressure water guns, steam car washing machines and automatic car washing machines.

[0003] Among them, high-pressure water gun car washing mainly uses a high-pressure water gun to spray high-pressure water to rinse the car, and cooperates with manual brushing and wiping to clean the car; steam car washing uses high-temperature steam and high-pressure jets to clean the vehicle; automatic car washing machine is a type of large-scale car washing equipment. During washing, the car is pulled into the automatic car washing machine, and the car is automatically cleaned through the cooperation of the high-pressure water gun and the washing roller. After cleaning, the car is manually wiped dry.

[0004] In the prior art, whether it is high-pressure water gun car washing, steam car washing or automatic car washing machine car washing, a large amount of water is needed to perform high-pressure washing on the outer surface of the car, and the stains adhered to the outer surface of the car are cleaned in combination with mechanical friction. These car washing equipments all have the problem of high water consumption. Among them, high-pressure water gun car washing and automatic car washing machine car washing even need to consume 150 liters of water to wash a car. This not only makes the water consumption of the car washing equipment high, but also the waste water generated by the washing will cause a certain degree of pollution to the environment. In addition, these car washing equipments need to be additionally equipped with corresponding car washing locations, clear water sources, power supplies and other equipment, which makes the use of the car washing equipment less environmentally friendly and convenient.

[0005] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0042] like Figures 1 to 13 As shown, a micro-water movable car washing device in one embodiment of the present invention includes: a vehicle frame 1, a closed brushing mechanism 2, a sewage return mechanism 3, and a rotary dust cleaning and squeezing mechanism 4.

[0043] like Figure 1As shown, a handrail 101 is fixedly mounted on one side of the frame 1. The frame 1 is pushed and controlled by supporting the handrail 101.

[0044] like Figure 1 As shown, a plurality of evenly distributed universal wheel groups 102 are fixedly mounted on the bottom of the frame 1. The plurality of universal wheel groups 102 are used to support and assist the movement of the frame 1.

[0045] like Figure 1 As shown, a battery 103 is fixedly mounted on the upper part of the frame 1. The battery 103 provides driving current for the air compressors 205 and 318.

[0046] Preferably, the battery 103 is a 12V iron phosphate battery.

[0047] like Figure 1 As shown, the closed scrubbing mechanism 2 is fixedly mounted on the frame 1, and the closed scrubbing mechanism 2 includes a positive pressure liquid storage tank 201, which is fixedly mounted on the frame 1. The cleaning liquid is stored in the positive pressure liquid storage tank 201. At the same time, the positive pressure liquid storage tank 201 can provide a closed space for pressurized delivery of the cleaning liquid.

[0048] Specifically, the positive pressure liquid storage tank 201 is a 10L stainless steel pressure tank with a load-bearing capacity of 12 kg / cm 2 above.

[0049] like Fig.13 As shown, the liquid outlet of the positive pressure liquid storage tank 201 is fixedly connected with a cleaning liquid pipe 202. The cleaning liquid in the positive pressure liquid storage tank 201 is led out through the cleaning liquid pipe 202.

[0050] like Figure 1 As shown, an air compressor 205 is fixedly installed above the vehicle frame 1. By controlling the operation of the air compressor 205, positive pressure gas and negative pressure gas are generated, so that the cleaning liquid stored in the positive pressure storage tank 201 can be pressurized and discharged by conveying positive pressure gas into the positive pressure storage tank 201. The negative pressure storage tank 303 can collect sewage under negative pressure by extracting negative pressure from the negative pressure storage tank 303.

[0051] Preferably, the air compressor 205 can provide 8-10 kg / cm 2 of low pressure.

[0052] like Figure 1As shown, a positive pressure delivery air pipe 206 is connected between the air outlet of the air compressor 205 and the air inlet of the positive pressure liquid storage tank 201. The positive pressure delivery air pipe 206 connects the air compressor 205 and the positive pressure liquid storage tank 201, so that positive pressure gas is continuously delivered to the positive pressure liquid storage tank 201 through the positive pressure delivery air pipe 206, thereby facilitating the pressurization and extraction of the cleaning liquid stored in the positive pressure liquid storage tank 201.

[0053] like Figure 6 As shown, one end of the cleaning liquid pipe 202 located in the positive pressure liquid storage tank 201 is connected to a liquid extraction pipe 207. It is convenient to extract the cleaning liquid in the positive pressure liquid storage tank 201 through the liquid extraction pipe 207.

[0054] like Figures 1 to 8 As shown, one end of the cleaning liquid pipe 202 away from the positive pressure liquid storage tank 201 is fixedly connected to a cleaning disc 203. The cleaning disc 203 is used to assemble and limit the multiple groups of cleaning nozzles 204. At the same time, the cleaning disc 203 can limit the spray range of the multiple groups of cleaning nozzles 204.

[0055] like Figure 1 to Figure 2 As shown, a plurality of evenly distributed cleaning nozzles 204 are fixedly connected to one side of the cleaning plate 203, and the plurality of cleaning nozzles 204 are all connected to the cleaning liquid pipe 202. The cleaning liquid is sprayed to the vehicle through the plurality of cleaning nozzles 204, so as to facilitate the brushing treatment of the vehicle.

[0056] Specifically, a cleaning nozzle 204 with different water outputs may be selected according to actual conditions.

[0057] like Figures 7 to 10 As shown, a vibration brush assembly is installed between the multiple cleaning nozzle groups 204. The vibration brush assembly includes a rotating connection seat 208, and the rotating connection seat 208 is rotatably installed between the multiple cleaning nozzle groups 204. The rotating connection seat 208 plays the role of assembly limit and rotation drive for the vibration brush shaft 209.

[0058] like Figures 7 to 10 As shown, a vibration brushing shaft 209 is slidably mounted in the rotating connection seat 208. The vibration brushing shaft 209 plays the role of assembling, fixing and rotating driving for multiple groups of brushing scrapers 213. A driving shaft 210 is slidably mounted in the vibration brushing shaft 209. The driving shaft 210 is set through the rotating connection seat 208.

[0059] like Figures 7 to 10 As shown, a connecting key 211 is arranged between the vibration brushing shaft 209 and the driving shaft 210. The connecting key 211 serves to lock the vibration brushing shaft 209 and the driving shaft 210 in rotation.

[0060] like Figures 7 to 10As shown, a vibration spring 212 is mounted on the outer side of the driving shaft 210, and the two ends of the vibration spring 212 are respectively connected to the rotating connection seat 208 and the vibration brushing shaft 209. The vibration spring 212 plays the role of connecting the rotating connection seat 208 and the vibration brushing shaft 209, and the vibration brushing shaft 209 can be connected and limited by the contraction and reset of the vibration spring 212.

[0061] like Figures 7 to 10 As shown, one end of the vibration brushing shaft 209 outside the rotating connection seat 208 is fixedly connected to a plurality of evenly distributed brushing scrapers 213. The brushing scrapers 213 play the role of assembling, fixing and rotating the cleaning brush 214.

[0062] There are three groups of scrubbing blades 213 , and the three groups of scrubbing blades 213 are evenly arranged on the outside of the vibrating scrubbing shaft 209 at an angle of 120°.

[0063] Specifically, a 15° angle is formed between the plane where the multiple groups of scrubbing blades 213 are located and the central axis of the vibration scrubbing shaft 209. By tilting the multiple groups of scrubbing blades 213, vertical friction between the cleaning brush 214 and the vehicle paint surface is avoided, thereby reducing the wear on the vehicle paint surface.

[0064] like Figures 7 to 10 As shown, the side of the multiple groups of scrubbing scrapers 213 away from the cleaning nozzle 204 is fixedly connected with a cleaning brush 214. The multiple groups of cleaning brushes 214 rotate along with the rotation of the scrubbing scrapers 213 to scrub and clean the vehicle.

[0065] like Figures 7 to 10 As shown, a control box 215 is fixedly connected to the side of the cleaning disc 203 away from the cleaning nozzle 204. The control box 215 plays a role in assembling and fixing the cleaning disc 203. At the same time, the control box 215 can be used to assemble and limit the driving motor 218.

[0066] like Figures 7 to 10 As shown, a limited chassis 216 is fixedly connected in the control box 215, and the limited chassis 216 is rotatably connected to one end of the rotating connection seat 208 located in the control box 215. The limited chassis 216 supports and slides the vibration slider 217.

[0067] It is worth noting that a gradually deepening annular groove is provided on one side of the limiting chassis 216 close to the rotating connection seat 208, and a vibration slider 217 is fixedly connected to one end of the rotating connection seat 208 located in the control box 215, and the vibration slider 217 is slidably assembled in the annular groove. The rotating connection seat 208 is reciprocatingly supported by the vibration slider 217 sliding in the gradually deepening annular groove, so as to facilitate vibration control of the vibration brushing shaft 209.

[0068] like Figures 7 to 10 As shown, one end of the driving shaft 210 located in the control box 215 is connected to the driving motor 218. The driving motor 218 provides power, and the driving shaft 210 is driven to rotate by controlling the operation of the driving motor 218, so as to facilitate driving the multiple groups of scrubbing scrapers 213 to rotate synchronously.

[0069] Specifically, the driving motor 218 is a 12V555 DC motor with a rotation speed of 600r / min and a power of 21W.

[0070] like Figures 7 to 10 As shown, the sewage return mechanism 3 is fixedly assembled on the top of the frame 1, and the sewage return mechanism 3 includes a water-absorbing cotton ring 301, which is fixedly assembled on one side of the cleaning disc 203, and the water-absorbing cotton ring 301 is sleeved on the outside of the multiple groups of cleaning nozzles 204. The wastewater flowing out during the vehicle cleaning process is absorbed by the water-absorbing cotton ring 301, which provides a basis for the subsequent recycling of wastewater. At the same time, the cleaning disc 203 can be buffered and protected by the water-absorbing cotton ring 301, so as to avoid the cleaning disc 203 directly contacting the vehicle surface, thereby scratching the vehicle paint surface. In addition, the water-absorbing cotton ring 301 can be deformed so that the cleaning disc 203 and the water-absorbing cotton ring 301 can be applied to the curved outer surface of the vehicle, thereby facilitating the formation of a closed scrubbing space on the outer surface of the vehicle.

[0071] It is worth noting that the water-absorbing cotton ring 301 is a PVA cotton ring.

[0072] like Figures 7 to 10 As shown, a plurality of groups of evenly distributed negative pressure suction nozzles 302 are fixedly connected to one side of the cleaning plate 203 close to the water-absorbing cotton ring 301. The sewage absorbed in the water-absorbing cotton ring 301 is collected under negative pressure by the plurality of groups of negative pressure suction nozzles 302.

[0073] Specifically, a negative pressure diversion component is fixedly mounted on the frame 1 , and the negative pressure diversion component is used to perform negative pressure diversion on the sewage absorbed in the absorbent cotton ring 301 .

[0074] like Figures 4 to 5 As shown, the negative pressure guide assembly includes a negative pressure liquid storage tank 303, which is fixedly mounted above the vehicle frame 1. The negative pressure liquid storage tank 303 collects the sewage in the cleaning tray 203 under negative pressure. An air intake pipe 304 is connected between the air outlet of the negative pressure liquid storage tank 303 and the air inlet of the air compressor 205. The negative pressure liquid storage tank 303 is placed in a negative pressure state by extracting the gas in the negative pressure liquid storage tank 303 through the air intake pipe 304, so as to facilitate the negative pressure collection of the wastewater of the cleaning process parameters.

[0075] Specifically, the negative pressure liquid storage tank 303 is an aluminum alloy liquid storage tank with a capacity of 5L and can withstand 12 kg / cm2 Negative pressure above.

[0076] like Figures 4 to 5 As shown, the liquid inlet of the negative pressure liquid storage tank 303 is fixedly connected with a reflux liquid pipe 305. The reflux liquid pipe 305 is used to guide and recycle the waste liquid.

[0077] like Figures 7 to 12 As shown, a liquid collecting member 306 is fixedly connected to one side of the cleaning plate 203, and the liquid collecting member 306 is mounted on the outside of the multiple groups of cleaning nozzles 204, and the liquid collecting member 306 is connected to the multiple groups of negative pressure suction nozzles 302, and the other end of the liquid collecting member 306 is connected to the return liquid pipe 305. The liquid collecting member 306 serves to connect the multiple groups of negative pressure suction nozzles 302 with the return liquid pipe 305, so as to facilitate the centralized diversion treatment of the wastewater collected by the multiple groups of negative pressure suction nozzles 302.

[0078] like Figures 1 to 3 As shown, a pair of fixing rods 307 are fixedly assembled between the cleaning disc 203 and the positive pressure liquid storage tank 201. The fixing rods 307 play the role of assembly limit for the winding shaft 309.

[0079] like Figures 1 to 3 As shown, a pair of fixed rods 307 are rotatably mounted on one side of the positive pressure liquid storage tank 201 with a reel 308, and the return liquid pipe 305 and the cleaning liquid pipe 202 are both wound around the outside of the reel 308. The reel 308 rotates to control the reeling of the return liquid pipe 305 and the cleaning liquid pipe 202, thereby avoiding the situation where the pipelines are cluttered.

[0080] like Figures 1 to 3 As shown, a winding shaft 309 is fixedly connected inside the winding wheel 308. The winding shaft 309 serves as an assembly limit for the winding wheel 308. A winding hand wheel 310 is fixedly connected to one end of the winding shaft 309. The winding wheel 308 is driven to rotate by controlling the rotation of the winding hand wheel 310.

[0081] like Figures 1 to 3 As shown, a fixing plate 311 is fixedly assembled between a pair of fixing rods 307. The fixing plate 311 plays a role of assembling and limiting the limiting clamp 312.

[0082] like Figures 1 to 3 As shown, a limit clip 312 is slidably mounted on one side of the fixing plate 311, and the limit clip 312 is used to clamp and limit the cleaning disc 203. The cleaning disc 203 is clamped and limited by the limit clip 312, so that the movement stability of the cleaning disc 203 is ensured.

[0083] like Fig. 9 As shown, the rotary dust cleaning and squeezing mechanism 4 is mounted on the outside of the cleaning disc 203, and the rotary dust cleaning and squeezing mechanism 4 is used for cyclically squeezing the absorbent cotton ring 301 and cleaning dust.

[0084] like Figures 7 to 10 As shown, the rotary dust cleaning and squeezing mechanism 4 includes a transmission gear box 401, and the transmission gear box 401 is sleeved on the outside of the control box 215. The transmission gear box 401 plays the role of assembly limit and drive control for the cleaning wheel 402.

[0085] like Figures 7 to 10 As shown, the outer side of the transmission gear box 401 is rotatably equipped with a cleaning wheel 402. The dust brush 404 is assembled and fixed by the cleaning wheel 402. At the same time, the cleaning wheel 402 can be driven to rotate so that the dust brush 404 can synchronously clean the vehicle.

[0086] like Figures 7 to 10 As shown, the cleaning wheel disc 402 is integrally formed with an inner gear ring 403 on one side close to the transmission gear box 401. The cleaning wheel disc 402 is driven and controlled by the inner gear ring 403 to rotate and drive the cleaning wheel disc 402.

[0087] like Figures 7 to 10 As shown, a cleaning brush 404 is fixedly connected to one side of the cleaning wheel 402 close to the water-absorbing cotton ring 301. The outer surface of the vehicle is cleaned and scrubbed by the cleaning brush 404. A wedge-shaped extrusion block 405 is arranged between the cleaning brush 404 and the water-absorbing cotton ring 301, and one side of the wedge-shaped extrusion block 405 is fixedly connected to the cleaning wheel 402. The water-absorbing cotton ring 301 is squeezed by the wedge-shaped extrusion block 405 rotating with the rotation of the cleaning wheel 402, thereby improving the effect of reflux collection of sewage absorbed in the water-absorbing cotton ring 301, ensuring the effect of the water-absorbing cotton ring 301 on absorbing sewage, and avoiding the situation where the water-absorbing cotton ring 301 has too much sewage and splashes sewage during use.

[0088] like Figures 7 to 10 As shown, a transmission gear 406 is rotatably mounted in the transmission gear box 401, and the transmission gear 406 is meshed with the inner gear ring 403. A driving gear 407 is meshed on the side of the transmission gear 406 away from the inner gear ring 403, and the driving gear 407 is fixedly sleeved on the outer side of the driving shaft 210. Through the mutual meshing of the transmission gear 406 and the driving gear 407, the cleaning wheel 402 can rotate synchronously with the rotation of the driving shaft 210 under the action of the inner gear ring 403.

[0089] like Fig.14As shown, a micro-water movable car washing device in another embodiment of the present invention is different from the previous embodiment in that an integrated liquid storage tank 5 can be used to replace the positive pressure liquid storage tank 201 and the negative pressure liquid storage tank 303, and the space occupied by the positive pressure liquid storage tank 201 and the negative pressure liquid storage tank 303 is simplified by using the integrated liquid storage tank 5. At the same time, the weight of the car washing device can be reduced and the convenience of mobile use of the car washing device can be improved.

[0090] like Fig.14 As shown, a partition 501 is integrally formed in the integrated liquid storage tank 5, and the partition 501 divides the inner cavity of the integrated liquid storage tank 5 into a positive pressure cavity 502 and a negative pressure cavity 503. The cleaning liquid can be stored and positively pressured through the positive pressure cavity 502, and the negative pressure cavity 503 is used to collect the sewage in the cleaning tray 203 under negative pressure.

[0091] During specific use, the frame 1 is moved to the vehicle to be cleaned by supporting the handrail 101, and then the cleaning tray 203 is pulled out, and the cleaning liquid pipe 202 is unfolded by rotating the winding wheel 308. The operator can hold the cleaning tray 203 and place it on the outer surface of the vehicle.

[0092] Subsequently, positive pressure gas is generated by controlling the operation of the air compressor 205, and the positive pressure gas is transported to the positive pressure liquid storage tank 201 through the positive pressure gas delivery pipe 206. At this time, the cleaning liquid in the positive pressure liquid storage tank 201 is transported to the multiple groups of cleaning nozzles 204 along the liquid extraction pipe 207 under the action of the gas pressure, and the cleaning liquid is sprayed onto the outer surface of the vehicle through the multiple groups of cleaning nozzles 204. At the same time, the driving shaft 210 can be driven to rotate by controlling the operation of the driving motor 218, so that the multiple groups of scrubbing scrapers 213 and the cleaning brushes 214 can rotate synchronously, and the outer surface of the vehicle can be scrubbed by the rotation of the cleaning brush 214 and the spraying of the cleaning nozzles 204;

[0093] When the driving shaft 210 rotates, the rotating connection seat 208 can reciprocate under the action of the vibration slider 217 and the limiting chassis 216, and the vibration brushing shaft 209 can be reciprocated by the movement of the rotating connection seat 208. At the same time, the vibration spring 212 is retracted and reset to make the vibration brushing shaft 209 vibrate with the reciprocating movement of the rotating connection seat 208. Through the vibration of multiple groups of vibration brushing shafts 209, multiple groups of inclined brushing scrapers 213 and cleaning brushes 214 can vibrate and clean the outer surface of the vehicle, thereby improving the cleaning effect of the outer surface of the vehicle. In addition, the inclined cleaning brush 214 avoids the situation where the cleaning brush 214 directly collides with the paint surface of the vehicle, greatly reducing the wear of the paint surface of the vehicle caused by the brushing process.

[0094] In addition, during the rotation of the driving shaft 210, the cleaning wheel 402 can rotate synchronously with the cooperation of the driving gear 407, the transmission gear 406 and the inner gear ring 403. The rotation of the cleaning wheel 402 drives the dust brush 404 to clean the outer surface of the vehicle, and the wedge-shaped squeezing block 405 rotates along with the rotation of the cleaning wheel 402 to squeeze the water-absorbing cotton ring 301. The squeezing of the water-absorbing cotton ring 301 by the wedge-shaped squeezing block 405 improves the efficiency of negative pressure collection of sewage absorbed in the water-absorbing cotton ring 301 by multiple groups of negative pressure suction nozzles 302, ensures the sewage absorption effect of the water-absorbing cotton ring 301, and avoids the water-absorbing cotton ring 301 from splashing sewage due to excessive sewage content.

[0095] During operation, the air compressor 205 can extract air from the negative pressure liquid storage tank 303 through the suction pipe 304, so that the negative pressure liquid storage tank 303 is in a negative pressure state, and the sewage absorbed in the water-absorbing cotton ring 301 is collected under negative pressure through the cooperation of the reflux liquid pipe 305, the liquid collecting part 306 and the multiple groups of negative pressure suction nozzles 302, thereby avoiding the pollution of the environment caused by sewage during the vehicle washing process, and improving the environmental protection of the vehicle washing equipment. Compared with the traditional car washing equipment, only 3L of water is needed to wash the vehicle, which can save 98% of water. At the same time, it does not rely on 220V municipal electricity, and can save 98.6% of electricity compared with steam car washing. In addition, 65% to 70% of the sewage generated during the car washing process can be recycled, which greatly reduces the pollution to the car washing ground.
