[0054] In the related art, the cleaning device for cleaning the camera usually adopts two independent power devices, namely an air pump air supply device and a water pump water supply device, resulting in a complex structure and high cost of the cleaning device.

[0055] In order to solve the above technical problems, the embodiments of the present application provide a cleaning device and a vehicle. The cleaning device and the vehicle provided by the embodiments of the present application will be introduced in detail below with reference to the accompanying drawings of the specification.

[0056] First, please refer to Figure 1 and Figure 2, a cleaning device 100 proposed in the first aspect of the present application includes a dual-outlet air pump 1, a water storage tank 2, and a spray head 3. The dual-outlet air pump 1 has a first air outlet interface 11 and a second air outlet interface 12. The first air outlet interface 11 outputs purging gas, and the second air outlet interface 12 outputs driving gas; the water storage tank 2 includes a tank body 21, and the tank body 21 has a first air inlet interface 211 and a first water outlet interface 212; the first air inlet interface 211 is connected to the second air outlet interface 12 to drive the first water outlet interface 212 to output cleaning liquid through the driving gas; the spray head 3 is connected to the first air outlet interface 11 or the first water outlet interface 212 through a valve connector 4 for spraying purging gas or cleaning liquid.

[0057] Among them, the tank body 21 of the water storage tank 2 contains cleaning liquid. There are various types of cleaning liquid, and the most commonly used cleaning liquid is water. Cleaning agents are also widely used cleaning liquids. The surfactants in the cleaning agents can effectively remove difficult-to-clean substances such as oil stains and dirt. When in use, cleaning liquids such as water, alkaline cleaning agents, acidic cleaning agents, or enzyme cleaning agents can be flexibly selected.

[0058] It can be understood that the first air outlet interface 11 of the dual-outlet air pump 1 can be connected to the spray head 3 through the valve connector 4, so that the purging gas generated by the dual-outlet air pump 1 is ejected from the spray head 3 after passing through the valve connector 4. The second air outlet interface 12 of the dual-outlet air pump 1 is connected to the first air inlet interface 211 on the tank body 21 of the water storage tank 2, and can fill the tank body 21 with driving gas, driving the cleaning liquid in the tank body 21 to be output from the first water outlet interface 212, so that the cleaning liquid is ejected from the spray head 3 after passing through the valve connector 4.

[0059] In the solution provided by the embodiments of the present application, on the one hand, the dual-outlet air pump 1 can directly deliver the purging gas for cleaning the camera to the spray head 3, and on the other hand, it can also deliver the cleaning liquid for cleaning the camera to the spray head 3 through the water storage tank 2. Therefore, this solution can realize the spraying of purging gas and cleaning liquid by the spray head 3 only through one power device, the dual-outlet air pump 1. This not only simplifies the technical solution of using two independent power devices, an air pump air supply device and a water pump water supply device, in the related art, but also eliminates the water pump water supply device. It can be seen that through the present application, the problems of complex structure and high cost of the cleaning device for cleaning the camera in the related art can be solved.

[0060] It should be noted that there are various implementation manners for driving the cleaning liquid in the tank body 21 to be output through the first water outlet interface 212. In one possible implementation manner, see Figure 3 and Figure 4, the water storage tank 2 may include a piston 22. The piston 22 is movably arranged in the tank body 21 and is located between the first air inlet interface 211 and the first water outlet interface 212. The piston 22 can move towards the first water outlet interface 212 under the action of the driving gas to apply pressure to the cleaning liquid in the tank body 21 and make the cleaning liquid output from the first water outlet interface 212. Among them, the piston 22 is hermetically connected to the inner wall of the tank body 21 to prevent the cleaning liquid from leaking from the gap between the piston 22 and the inner wall of the tank body 21. The piston 22 can be circular, rectangular, etc. The designer can flexibly set the shape and size of the piston 22 according to the internal space of the water storage tank 2, which will not be elaborated here.

[0061] In some embodiments, referring to Figure 3 and Figure 4 , the water storage tank 2 may further include a reset member 23. The reset member 23 is connected to the piston 22 and the tank body 21 and is used to make the piston 22 return to the initial position when the second air outlet interface 12 stops outputting the driving gas.

[0062] Among them, the reset member 23 can adopt a reset spring, a reset rubber, etc. When the second air outlet interface 12 stops outputting the driving gas, the piston 22 can return to the initial position under the action of the reset member 23 and stop delivering the cleaning liquid to the nozzle 3. In addition, after the piston 22 returns to the initial position, the cleaning liquid can be replenished into the tank body 21 so that the tank body 21 can provide sufficient cleaning liquid for the next camera cleaning.

[0063] Referring to Figure 1 and Figure 2 , in some embodiments, the valve connecting member 4 may include a three-way one-way valve 41. The three-way one-way valve 41 may include a switching member 414 and a first connecting pipe 411, a second connecting pipe 412, and a third connecting pipe 413 that are connected to each other; the first connecting pipe 411 is connected to the first air outlet interface 11, the second connecting pipe 412 is connected to the first water outlet interface 212, and the third connecting pipe 413 is connected to the nozzle 3; the switching member 414 is movably arranged in the first connecting pipe 411 and / or the second connecting pipe 412. The switching member 414 can make the purging gas flow unidirectionally from the first connecting pipe 411 to the third connecting pipe 413, and make the cleaning liquid flow unidirectionally from the second connecting pipe 412 to the third connecting pipe 413.

[0064] Among them, the structural form of the switching member 414 can be various. In a possible implementation manner, referring to Figure 5, the switching member 414 may include a first valve plate 4141 and a second valve plate 4142. The first valve plate 4141 and the second valve plate 4142 are respectively rotatably disposed on the first connecting pipe 411 and the second connecting pipe 412. The first valve plate 4141 is rotatably disposed on the inner wall of the first connecting pipe 411 and can unidirectionally open or close the flow passage of the first connecting pipe 411. The second valve plate 4142 is rotatably disposed on the inner wall of the second connecting pipe 412 and can unidirectionally open or close the flow passage of the second connecting pipe 412. In another possible implementation, the switching member 414 may include a valve core (not shown in the figure). The valve core is movably disposed at a first position of the first connecting pipe 411 and a second position of the second connecting pipe 412. When the valve core is in the first position, the first connecting pipe 411 may communicate with the third connecting pipe 413. When the valve core is in the second position, the second connecting pipe 412 may communicate with the third connecting pipe 413.

[0065] The cleaning device 100 of the present application can not only clean a single camera, but also clean multiple cameras. When there are multiple cameras to be cleaned, in some embodiments, the number of nozzles 3 can be multiple. At this time, the valve connector 4 may include at least one three-way valve 42. The multiple nozzles 3 are connected to the purge gas or cleaning liquid through the three-way one-way valve 41 and the three-way valve 42. See Figure 2 , by adding the three-way valve 42, the number of nozzles 3 can be expanded. It can be understood that for each additional three-way valve 42, one more nozzle 3 can be added. The three-way valve 42 can be respectively connected to the three-way one-way valve 41 and the nozzle 2 through hoses, and has the advantages of convenient and flexible installation and expansion.

[0066] In some embodiments, the water storage tank 2 may further include a controller (not shown in the figure). The controller is electrically connected to the dual-outlet air pump 1. Among them, the controller can control the start and stop of the dual-outlet air pump 1, as well as the control of the air pressure, air flow direction, gas volume, etc. of the gas after starting, so as to realize the timed automatic cleaning of the camera, and the nozzles 3 alternately spray the cleaning liquid and the purge gas to achieve rapid air drying.

[0067] In some embodiments, the cleaning device 100 may further include an image sensor (not shown in the figure). The image sensor is electrically connected to the controller and is used to detect whether the camera needs to be cleaned.

[0068] Among them, the image sensor can be set to collect images of the camera within a certain time period (such as 24h, 48h, etc.), and compare the collected images with the stored images of the clean camera. When the comparison result meets the preset conditions (such as the similarity is less than or equal to the preset threshold), it is determined that the camera needs to be cleaned. At this time, the image sensor can send a trigger signal to the controller to make the controller control the dual-outlet air pump 1 to work and clean the camera in time.

[0069] Secondly, please refer to Figure 2 In the second aspect of the present application, a vehicle is further proposed, which includes an on-vehicle camera and the cleaning device 100 described in any one of the first aspects above. The cleaning device 100 is used to clean the on-vehicle camera.

[0070] Among them, the image data collected by the on-vehicle camera can display the conditions of the road and the surrounding of the vehicle in real time, such as lane lines, vehicle flow, pedestrian flow, etc., for the driver's reference, so that the driver can timely adjust the driving state of the vehicle and ensure the driving safety of the vehicle. When the external environment of the vehicle changes, such as rain, snow, haze, mud and water, dust and flying insects, etc. cause the camera to be dirty, or in extremely cold or hot environments, when the lens of the on-vehicle camera gets fogged or iced and becomes unclear, the cleaning device 100 can spray cleaning liquid and purge gas onto the surface of the on-vehicle camera through the nozzle 3, effectively washing away the dirt on the surface of the on-vehicle camera and realizing the cleaning of the on-vehicle camera.

[0071] Since the vehicle provided by the present application has the cleaning device 100 of the above embodiment, it has all the beneficial effects of the cleaning device 100. The specific structure of the cleaning device 100 has been described in detail above and will not be repeated here.

[0072] In some embodiments, the vehicle may further include an electronic control unit, and the electronic control unit is electrically connected to the dual-outlet air pump 1.

[0073] Among them, the electronic control unit of the vehicle is similar to the controller described above, and can control the start and stop of the dual-outlet air pump 1, as well as the control of the air pressure, air flow direction, air volume, etc. of the gas after it is turned on. The electronic control unit can adopt a separate control module or can be integrated in the central control system of the vehicle, that is, the central control console. The central control console is located in front of the driver's seat and the passenger seat, and the user can conveniently call out the control interface of the electronic control unit through the central control console to realize the control of the dual-outlet air pump 1.

[0074] In some embodiments, the vehicle may further include a water tank (not shown in the figure). The water tank is connected to the tank body 21 through a water injection pipe 213 and is used to supplement cleaning liquid to the tank body 21. A one-way valve (not shown in the figure) is provided on the water injection pipe 213.

[0075] Refer to Figure 3 and Figure 4 , the water injection pipe 213 can be arranged near the first water outlet interface 212 of the tank body 21. It can be understood that the water tank stores cleaning liquid, and when the cleaning liquid in the tank body 21 is insufficient, the cleaning liquid can be supplemented to the tank body 21 through the water injection pipe 213. When the piston 22 pushes the cleaning liquid to be output from the first water outlet interface 212, the one-way valve on the water injection pipe 213 can prevent the cleaning liquid from overflowing out of the water injection pipe 213.

[0076] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered within the scope of the claims and the specification of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
