Fig. 1 to 8 show a vehicle washing system 100 according to a preferred embodiment of the present invention, which is installed in a vehicle 200 for washing at least one device 300 to be washed, wherein the device 300 to be washed is not limited to a headlamp, a front windshield, a rear windshield, a camera, a rearview mirror, a license plate, or the like. Such as, but not limited to, a sedan, a bus or a truck, etc. By way of example, the vehicle 200 is embodied as a typical sedan, such as a 4-seater sedan.

Generally, the locations of different ones of the devices 300 to be cleaned are substantially different in the vehicle 200. For example, the front headlight includes 2 lamps respectively located at two sides of the front end of the vehicle 200, the front and rear windshields are respectively located at the front and rear of the cabin of the vehicle 200, the camera is located at the rear side of the vehicle 200 like a reversing camera, or a plurality of cameras are added at the front or rear of the vehicle, the rearview mirrors are located at the ears at two sides of the vehicle 200, the license plate generally includes 2 license plates respectively located at the rear or front of the vehicle 200, and so on. It can be seen that the outer surface of the cleaning device 300 is usually exposed to the outside and is easily contaminated by dust or traces of rain, etc. which may obstruct the normal operation of the cleaning device 300, and therefore, in order to keep the cleaning device 300 working normally, the vehicle cleaning system 100 is used to clean the dirt or traces of rain, etc. on the outer surface of the cleaning device 300.

As shown in fig. 2 and 3, in the present embodiment, the vehicle washing system 100 includes a water tank 10, at least one washing pump 20, a control center 30, at least one pipe 40, and at least one air source 50, wherein the water tank 10 is used for storing a washing liquid, such as glass water, which has a significant cleaning effect on the dirt on the surface of the equipment 300 to be cleaned. The water inlet 201 of the cleaning pump 20 is communicated with the water tank 10 and the water outlet 202 of the cleaning pump 20 is communicated with the pipeline 40, wherein the gas source 50 is communicated with the pipeline 40, wherein the control center 30 is configured to intelligently or manually control the cleaning pump 20 to selectively spray the cleaning liquid in the water tank 10 to the corresponding device 300 to be cleaned through the corresponding pipeline 40 and control the gas source 50 to fill gas into the pipeline 40 after the cleaning liquid is sprayed out correspondingly so as to remove residual liquid remaining in the pipeline 40.

In other words, each of the pipes 40 has at least one water outlet 401, the water outlet 401 of each of the pipes 40 is extended to the surface of each of the devices 300 to be cleaned, wherein the cleaning pump 20 sprays the cleaning solution in the water tank 10 to the surface of the corresponding device 300 to be cleaned through the corresponding pipe 40, and after the operation of the cleaning pump 20 is stopped, that is, after the cleaning pump 20 stops pumping the cleaning solution in the water tank 10 into the pipe 40, the gas source 50 fills gas into the corresponding pipe 40, so that the residual liquid in the pipe 40 is continuously discharged from the water outlet to the surface of the device 300 to be cleaned. That is, the gas source 50 inflates the pipe 40 with the residual liquid to discharge the residual liquid remaining in the pipe 40, thereby preventing freezing, deposition of dirt, etc. of the residual liquid remaining in the pipe 40 at a sub-zero temperature. Meanwhile, the residual liquid can be continuously sprayed to the surface of the equipment 300 to be cleaned so as to realize the re-cleaning and utilization of the residual liquid, and the waste of resources is avoided.

As shown in fig. 4A, further, the pipe 40 has two inlets, specifically divided into a water inlet 402 and a gas inlet 403, wherein the cleaning pump 20 pumps the cleaning liquid in the water tank 10 from the water inlet 402 into the pipe 40 (also called cleaning pipe 40) and out from the water outlet 401, and wherein the gas source 50 fills the pipe 40 with gas from the gas inlet 403 and discharges the gas from the water outlet 401. Preferably, the water inlet 402 and the air inlet 403 are juxtaposed at the head end of the pipeline 40, and the water outlet 401 is located at the tail end of the pipeline 40. In other words, the cleaning liquid is pumped into the head end of the pipe 40 from the water inlet 402 and discharged from the tail end of the pipe 40, and the gas is filled into the head end of the pipe 40 from the gas inlet 403 and discharged from the tail end of the pipe 40. That is, after the control center 30 controls the cleaning pump 20 to stop operating, i.e., stops pumping the cleaning solution into the pipe 40, the control center 30 controls the gas source 50 to fill the gas into the gas filling port 403 of the pipe 40, so that the residual solution in the pipe 40 can be continuously and completely discharged, i.e., the residual solution in the pipe 40 is hardly remained.

As shown in fig. 5, the present embodiment further provides a method for discharging a residual liquid from the vehicle washing system, which comprises the following steps:

after the cleaning pump 20 stops filling the cleaning solution into the water inlet 402 of the cleaning pipeline 40, filling gas into the inflation inlet 403 of the cleaning pipeline 40, so that residual liquid in the cleaning pipeline is discharged from the water outlet 401 of the cleaning pipeline 40, wherein the water inlet 402 and the gas inlet 403 of the cleaning pipeline 40 are located at the same end, and the water outlet 401 of the cleaning pipeline 40 is located at the other end.

As shown in fig. 4B, alternatively, the pipe 40 may have only one inlet, i.e. the water inlet 402 and the air inlet 403 are combined into one inlet with a larger size. The water outlet of the cleaning pump 20 and the air outlet of the air source 50 are both communicated with the inlet of the pipeline 40, which can also respectively realize the operations of spraying cleaning liquid and discharging the residual liquid in the pipeline, and are not described herein.

In order to ensure that the cleaning liquid in the pipeline 40 does not flow back, the cleaning pump 20 and the gas source 50 are both communicated with the pipeline 40 by using one-way valves, that is, the cleaning pump 20 can unidirectionally charge the cleaning liquid in the water tank 10 into the pipeline 40 and discharge the cleaning liquid from the water outlet 401, and the gas source 50 can unidirectionally charge the gas into the pipeline 40 and discharge the gas from the water outlet 401.

In addition, the water outlet of the cleaning pump 20 and the air charging port of the air source 50 are hermetically connected with the pipeline 40, so as to prevent the phenomena of leakage of the cleaning solution or air leakage. Such as a cold plastic seal, a hot melt seal, a gasket seal, or a ferrule seal, etc., without limitation.

As shown in fig. 6A, further, the gas source 50 includes an inflating body 51 and a driving mechanism 52, wherein the inflating body 51 communicates with the outside and the gas inlet 403 of the duct 40, wherein the driving mechanism 52 is mounted on the inflating body 51 and electrically connected to the cleaning pump 20, and wherein the driving mechanism 52 drives the inflating body 51 to inflate the outside gas into the duct 40. The driving mechanism 52 drives the inflating body 51 to inflate the duct 40 with gas in response to a closing signal of the washing pump 20, and is automatically closed after a certain time.

Preferably, the air source 50 is implemented as an electrically powered inflator, wherein the air inlet of the air source 50 is directly connected to the outside to generate power to fill the duct 40 with outside air through the driving mechanism 52. The inflatable body 51 has a one-way inflation valve 511, wherein the one-way inflation valve 511 is disposed between the air inlet 501 and the inflation port 502 of the inflatable body 51, wherein the one-way inflation valve 511 is in sealed communication with the air inlet 403 of the duct 40, so that the external air can enter the duct 40 in one way through the one-way inflation valve 511 to prevent the liquid in the duct 40 from flowing into the air source 50.

In another embodiment, as shown in fig. 6B, the air source 50 can be implemented as an air pressure tank capable of storing a certain air pressure, i.e. the air source 50 has an inflatable air pressure chamber 550, wherein the air pressure chamber 550 can be stored with compressed air through the air inlet 501, wherein the air pressure chamber 550 is communicated with the air inlet 403 of the pipeline 40 through an air pressure valve 551 arranged at the air charging port 502 of the air source 50. Accordingly, the pneumatic valve 551 is electrically connected to the control center 30 to control the opening and closing of the pneumatic valve 551 after the corresponding purge pump 20 is closed, thereby completing the residual liquid discharge operation of the corresponding pipeline 40. Alternatively, the pneumatic valve 551 may be electrically connected to the corresponding purge pump 20, and the pneumatic valve 551 may be automatically opened in response to a closing signal of the corresponding purge pump 20, thereby completing the remaining liquid discharge operation of the corresponding pipe 40.

Preferably, the inflatable body 51 of the air source 50 is installed beside the washer pump 20, and the inflation inlet 502 of the air source 50 is juxtaposed with the water outlet 202 of the washer pump 20, so that the water inlet 402 and the air inlet 403 of the duct 40 are as close as possible, to reduce unnecessary duct length, save material and space.

As shown in fig. 8A, the types of the washing pumps 20 applied to the different apparatuses 300 to be washed are different according to the water pressure. In this embodiment, the cleaning pump 20 is implemented as four, including a windshield cleaning pump 20A, a headlight cleaning pump 20B, a camera cleaning pump 20C, and a license plate cleaning pump 20D. The ducts 40 are correspondingly implemented in four, including a windshield washer duct 40A, a headlight washer duct 40B, a camera washer duct 40C, and a license plate washer duct 40D. The air sources 50 are correspondingly implemented in four, including a windshield air source 50A, a headlight air source 50B, a camera air source 50C, and a license plate air source 50D. Preferably, the windshield washer pump 20A, the headlight washer pump 20B, the camera washer pump 20C, and the license plate washer pump 20D are all connected to the water tank 10.

Accordingly, the windshield washer duct 40A has two water outlets 401, one water inlet 402 and one air inlet 403, wherein the water inlet 402 of the windshield washer duct 40A is communicated with the windshield washer pump 20A, wherein the air inlet 403 of the windshield washer duct 40A is communicated with the windshield air source 50A, and wherein the two water outlets 401 of the windshield washer duct 40A extend to the front and rear windshields of the vehicle 200, respectively. The headlight cleaning pipe 40B has two water outlets 401 of two headlights which extend to two sides of the head of the vehicle 200, one water inlet 402 which is connected to the headlight cleaning pump 20B, and one air inlet 403 which is connected to the headlight air source 50B. The camera purge conduit 40C has at least one said water outlet 401 extending to at least one camera of the vehicle, one said water inlet 402 communicating with the camera purge pump 20C and one said air inlet 403 communicating with the camera air supply 50C. The license plate cleaning duct 40D has two water outlets 401 respectively extending to the front and rear license plates of the vehicle 200, one water inlet 401 communicating with the license plate cleaning pump 20D, and one air inlet 403 communicating with the license plate air source 50D.

Further, the control center 30 is electrically connected to the windshield washer pump 20A, the headlight washer pump 20B, the camera washer pump 20C and the license plate washer pump 20D by selectable switches, wherein the control center 30 is configured to receive a manual or intelligent selection to turn on or off one or more of the windshield washer pump 20A, the headlight washer pump 20B, the camera washer pump 20C and the license plate washer pump 20D. For example, when the front and rear windshield of the vehicle need to be cleaned, the user can control the control center 30 to open or close the windshield cleaning pump 20A to spray a certain amount of cleaning liquid to the windshield through the windshield cleaning pipe 40A. Or when the sensor of the vehicle detects that the windshield needs to be cleaned, the control center 30 intelligently opens or closes the windshield cleaning pump 20A to spray a certain amount of cleaning liquid to the windshield through the windshield cleaning pipeline 40A, so as to complete the cleaning operation of the windshield.

As shown in fig. 7B, preferably, the motor of the louver cleaning pump 20A is electrically connected to the driving mechanism 52 of the louver air source 50A, wherein a closing signal of the motor of the louver cleaning pump 20A is used as an opening signal of the driving mechanism 52 of the louver air source 50A, that is, when the louver cleaning pump 20A is closed, an opening signal is fed back to the driving mechanism 52 of the louver air source 50, so that the driving mechanism 52 of the louver air source 50A is started, and then the external air is filled into the louver cleaning pipe 40A, so that the residual liquid in the louver cleaning pipe 40A is discharged. Further, the air window air source 50A is set by default to be opened for a certain time and then automatically closed, that is, the air window air source 50A is automatically closed after continuously filling the air window cleaning pipeline 40A with air for a certain time after being opened, so that the residual liquid in the air window cleaning pipeline 40A is completely discharged, the air window air source 50A is closed in time, and energy is saved. In other words, after the control center 30 controls the window cleaning pump 20A to start and spray a certain amount of liquid through the window cleaning pipe 40A, the window cleaning pump 20A is closed to stop filling the window cleaning pipe 40A with the cleaning liquid, wherein the window air source 50A fills the window cleaning pipe 40A with air in response to the window cleaning pump 20A being closed, and automatically closes after a certain time, and stops filling air.

Accordingly, the motor of the headlight purge pump 20B is electrically connected to the drive 52 of the headlight air supply 50B, wherein a switch-off signal of the motor of the headlight purge pump 20B is used as a switch-on signal of the drive 52 of the headlight air supply 50B, and the drive 52 of the headlight air supply 50B is also switched on by default for a certain time and then automatically switched off. The motor of the camera purge pump 20C is electrically connected to the driving mechanism 52 of the camera air supply 50C, wherein a turn-off signal of the camera purge pump 20C is used as a turn-on signal of the camera air supply 50C, and the camera air supply 50C is turned off automatically after being turned on for a certain time by default.

Accordingly, the driving mechanism 52 of the headlight air supply 50B is electrically connected to the control center 30, and after the control center 30 controls to turn off the headlight cleaning pump 20B, the control center 30 immediately turns on the headlight air supply 50B and turns off the headlight air supply 50B after a certain time, or the headlight air supply 50B automatically turns off after a certain time. The driving mechanism 52 of the camera air supply 50C is electrically connected to the control center 30, and after the control center 30 controls to turn off the camera cleaning pump 20C, the control center 30 turns on the driving mechanism 52 of the camera air supply 50C and turns off the camera air supply 50C after a certain time, or the camera air supply 50C is automatically turned off after a certain time. The driving mechanism 52 of the license plate air source 50D is electrically connected to the control center 30, and after the control center 30 controls to turn off the license plate cleaning pump 20D, the control center 30 turns on the driving mechanism 52 of the license plate air source 50D, and turns off the license plate air source 20D after a certain time, or the license plate air source 50D is automatically turned off after a certain time.

As shown in fig. 6C and 8B, in the second modified embodiment of the present preferred embodiment, not only a large amount of space is occupied but also the cost is high due to the arrangement of the plurality of air sources. Each of the gas sources 50 described above can be implemented as a common gas source. Specifically, the gas source 50 further comprises at least one on-off valve 53.

Fig. 9 to 11 show a vehicle cleaning system 100A according to a first modified embodiment of the present invention, which is different from the vehicle cleaning system 100 according to the preferred embodiment in that the vehicle cleaning system 100A according to the modified embodiment adopts the exhaust air of the existing air-out device 210 in the vehicle 200 as the air source 50, and other similar structures to those of the preferred embodiment are not repeated herein. The air outlet device 210 is not limited to a vehicle-mounted air conditioner, a vehicle-mounted fresh air system, or a vehicle-mounted purifier, and the like, and the air outlet device 210 has at least one air outlet 211, that is, the air outlet 211 can exhaust air to the outside, such as an air outlet of an air conditioner, an air outlet of a fresh air system, or an air outlet of a purifier, and the like. Generally, during the driving process, the wind outlet device 210 of the vehicle 200 usually keeps operating all the time, so that the wind outlet 211 keeps in the wind outlet state all the time, and due to the wind pressure of the wind outlet device 210, the gas exhausted from the wind outlet 211 generally has a certain wind pressure, and the wind pressure of the wind outlet 211 is controlled by the working mode of the wind outlet device 210. For example, in winter, the air conditioner may be kept running all the time when driving, so that the air outlet 211 may be kept in an air outlet state all the time.

As shown in fig. 9A and 10, in particular, the vehicle washing system 100A includes a water tank 10, at least one washing pump 20, a control center 30, at least one washing pipe 40, at least one air charging pipe 60, and at least one switching valve 53, wherein the water tank 10 is used for storing washing liquid. The water inlet 201 of the cleaning pump 20 is communicated with the water tank 10 and the water outlet 202 of the cleaning pump 20 is communicated with the water inlet 402 of the cleaning pipeline 40. The inlet 402 of the purge line 40 is adjacent to the inlet 403. The air charging ports 601 of the air charging ducts 60 are respectively communicated with the air inlets 403 of the cleaning ducts 40, wherein the air inlets 602 of the air charging ducts 60 are all communicated with the air outlets 211 of the air dischargeable device 210. The switch valves 53 are respectively switchably installed on the gas filling pipes 60 to open or close the gas filling pipes 60, wherein the control center 30 is configured to intelligently or manually control the cleaning pump 20 to selectively spray the cleaning liquid in the water tank 10 to the corresponding device 300 to be cleaned through the corresponding cleaning pipe 40, so as to clean the device 300 to be cleaned.

In this embodiment, the switch valves 53 are electrically connected to the control center 30, wherein the control center 30 opens the switch valve 53 corresponding to the purge pump 20 while closing the purge pump 20, and then conducts the inflation pipeline 60 corresponding thereto, so that the air discharged from the air outlet 211 of the air outlet device 210 can enter the corresponding purge pipeline 40 through the conducted inflation pipeline 60, and discharge the residual liquid in the purge pipeline 40 from the water outlet 401 of the purge pipeline 40. After a certain time, the on-off valve 53 is automatically closed or controlled by the control center 30 to close the inflation duct 60 again. That is, after one of the cleaning pumps 20 is turned off, the switch valve 53 connected to the air charging pipe 60 of the cleaning pipe 40 corresponding to the cleaning pump 20 is turned on for a certain time and then turned off again, so that the air discharged from the air outlet 211 can enter the cleaning passage 40 through the air charging passage 60 during the time when the switch valve 53 is turned on, and the residual liquid in the cleaning passage 40 is discharged by the air pressure. In other words, the switch valve 53 is opened for a certain time only after the corresponding cleaning pump 20 is turned off, and the switch valve 53 is always kept closed during most of the time when the cleaning device 300 is not cleaned, so that the gas in the air outlet 211 cannot enter the cleaning channel 40.

It should be mentioned that, in order to ensure that the air outlet 211 discharges air normally, the air inlet area of the air inlet 602 of the air charging channel 60 is smaller than the air outlet area of the air outlet 211, so that when the air charging channel 60 is closed, the air outlet 211 can discharge air normally. It should be noted that, in order to ensure that the wind pressure entering the air charging channel 60 from the wind outlet 211 is enough to discharge the residual liquid in the cleaning pipes 40, a plurality of air charging pipes 60 may share a wind inlet 602, and then each air charging port 601 of the air charging pipes 60 is respectively communicated with the corresponding cleaning pipe 40.

Therefore, the exhaust air of the air exhaling device 210 in the vehicle 200 is used as the residual liquid discharged from the cleaning pipeline 40, thereby realizing the utilization of waste gas, saving energy and the like.

As shown in fig. 9B, in another embodiment of this embodiment, the switch valves 53 may also be electrically connected to the motors of the purge pumps 20, respectively, and after the motors of the purge pumps 20 are turned off, the purge pumps 20 feed back an opening command to the corresponding switch valves 53, so that the corresponding switch valves 53 are opened, and then the corresponding gas charging pipes 60 are conducted, so that the residual liquid in the purge pipes 40 connected to the purge pumps 20 is discharged. Accordingly, the on-off valve 53 is set to automatically close after a certain time elapses from the opening.

To ensure that after the device 300 to be cleaned is cleaned, the air outlet 211 of the air outlet device 210 is kept to be filled with air into the corresponding air charging pipe 60, so that the residual liquid in the corresponding cleaning pipe 40 can be discharged. As shown in fig. 11A, the vehicle cleaning system 100A further includes an airflow monitoring device 70, wherein the airflow monitoring device 70 includes an airflow sensor 71 and an airflow controller 72, when any one of the switch valves 53 is opened, the airflow sensor 71 detects whether the air outlet 211 of the air-outable device 210 is continuously exhausting air and feeds back information to the airflow controller 72, based on the feedback information, if the air-outable device 210 is not exhausting air, the airflow controller 72 sends an opening signal to the air-outable device 210 to control the air-outable device 210 to open air and close the air-outable device 210 after a certain time, so that the air outlet 211 generates wind pressure to exhaust the residual liquid in the corresponding cleaning pipeline 40, and after the residual liquid is exhausted, the air-outable device 210 continues to return to the closed state. That is, the airflow monitoring device 70 controls the air outlet 211 to always allow air to enter the corresponding inflation pipeline 60 when any one of the on-off valves 53 of the air outlet device 210 is opened, so as to complete the remaining liquid discharge.

Further, the airflow sensor 71 is mounted at the outlet 211 of the air outlet device 210, so that the detection sensitivity and the information accuracy can be ensured.

As shown in fig. 11A, the air flow monitoring device 70 may be electrically connected to the control center 30, and the control center 30 controls the air flow sensor 71 of the air flow monitoring device 70 to start the above-mentioned detection operation while controlling any one of the washing pumps 20 to be turned off, so as to complete the discharge of the residual liquid from the corresponding washing pipeline 40 in cooperation with the opening of the on-off valve 53. Alternatively, as shown in fig. 11B, the air flow monitoring device 70 may be electrically connected to each of the purge pumps 20, and when any one of the purge pumps 20 is turned off, the air flow sensor 71 of the air flow monitoring device 70 performs the above-mentioned detection operation in response to a turn-off signal of the purge pump 20, so that the air outlet 211 keeps air flow to the corresponding purge line 40 to discharge the residual liquid.
