[0028] Ginseng Figure 1 In some embodiments, the camera system of the embodiment of the present application includes a camera and a cleaning device 100. The cleaning device 100 includes a mixing chamber structure 11, a liquid storage tank 12 and a spraying member 2.

[0029] The mixing chamber structure 11 is surrounded by a mixing chamber 111 having an outlet 1110 and a liquid inlet through hole 112 and an air inlet through hole 113 connected to the mixing chamber 111. The liquid storage tank 12 is provided with a liquid storage chamber 121 connected to the mixing chamber 111, and the liquid storage tank 12 sprays liquid into the mixing chamber 111 through the liquid inlet through hole 112. The jet element 2 sprays gas into the mixing chamber 111 through the air inlet through hole 113. The distance between the liquid inlet through hole 112 and the outlet 1110 is smaller than the distance between the air inlet through hole 113 and the outlet 1110.

[0030] The cleaning device 100 flushes away dirt and foreign matter through the gas-liquid mixture sprayed out from the mixing chamber 111, thereby cleaning the object to be cleaned more effectively and achieving a better cleaning effect.

[0031] In addition to being used in monitoring products to keep windows clean and reduce image interference, the cleaning device 100 of the embodiment of the present application can also be applied to products that use various lenses, sensors, etc. that need to be cleaned, such as lenses, radars and other sensors on cars. This application does not limit the application scenarios of the cleaning device 100.

[0032] The liquid stored in the liquid storage chamber 121 can be water, cleaning liquid, or a mixture of water and cleaning liquid. The present application does not limit the type of liquid.

[0033] In some embodiments, the jet component 2 may be an air pump or a container for containing gas. The present application does not limit the type of the jet component 2 , as long as it can spray gas into the mixing chamber 111 .

[0034] In some embodiments, the mixing chamber 111 extends along the first direction D1, the liquid inlet hole 112 and the air inlet hole 113 both extend along the second direction D2, the liquid inlet hole 112 is connected to the liquid storage tank 12, an angle is formed between the first direction and the second direction, and there is a gap between the axis of the liquid inlet hole 112 and the axis of the air inlet hole 113.

[0035] In some embodiments, the first direction D1 is perpendicular to the second direction D2 , and the present application does not limit the angle between the first direction D1 and the second direction D2 .

[0036] Ginseng Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in some embodiments, the cleaning device 100 includes a housing 1, and the housing 1 encloses a mixing chamber 111. The liquid storage tank 12 is a part of the housing 1. The cleaning device 100 includes a connecting pipe 3 connecting the liquid storage chamber 121 and the mixing chamber 111, and the fluid in the liquid storage chamber 121 flows through the connecting pipe 3 into the mixing chamber 111.

[0037] The shell 1 is also provided with an air storage chamber 114 , and at least part of the connecting tube 3 is located in the air storage chamber 114 . When the air pressure in the air storage chamber 114 changes, the connecting tube 3 is squeezed to spray liquid into the mixing chamber 111 .

[0038] In order to control the small amount of liquid, the gas storage process of high-pressure gas is used to squeeze the connecting tube 3, and the squeezed liquid amount is the volume reduced after the connecting tube 3 is deformed. The liquid dosage control utilizes the high-pressure gas to squeeze the connecting tube 3 to supply, realizing the function of extremely small liquid dosage, effectively reducing additional maintenance work such as manual liquid addition.

[0039] In some embodiments, when the gas storage chamber 114 is inflated and pressurized, the liquid in the connecting tube 3 is squeezed into the mixing chamber 111. When gas is supplied to the mixing chamber 111, the gas blows the small droplets into a mist, forming a gas-liquid mixture that is ejected from the outlet 1110. The cleaning device 100 adopts a liquid-gas combination method, using a small amount of liquid to form a gas-liquid mixture, and cleans the cleaning object under high pressure. The liquid infiltration reduces the adhesion, and the high-pressure gas blows away to improve the cleaning effect.

[0040] In some embodiments, the outlet 1110 may be connected to a pipe of a suitable length or various nozzles to more effectively clean the object to be cleaned, which is not limited in the present application.

[0041] In some embodiments, the connecting tube 3 located in the gas storage chamber 114 is a hose, so that the connecting tube 3 is deformed when squeezed by high-pressure gas to ensure that the mixing chamber 111 can spray liquid normally, and the amount of liquid squeezed out is the volume reduced after the hose is deformed.

[0042] When the hose is squeezed and deformed by high-pressure gas, the volume inside the hose becomes smaller, and the amount of liquid squeezed out is equal to the amount of volume reduction of the hose. Since the hose itself is small in volume, the amount of volume reduction is also small, so the amount of liquid squeezed out is also small, thus achieving the goal of supplying a smaller amount of liquid. When the liquid supply needs to be adjusted as needed, it can be achieved by adjusting the length and cross-sectional size of the hose.

[0043] In some embodiments, the liquid storage chamber 121 and the mixing chamber 111 may also be directly connected, thereby saving the connecting tube 3 and saving space.

[0044] In some embodiments, the shell 1 encloses a liquid storage chamber 121 , which has a compact structure and saves processing steps and assembly steps.

[0046] In some embodiments, the opening directions of the air storage cavity 114 and the liquid storage cavity 121 are the same.

[0047] In some embodiments, the mixing chamber 111 is disposed on the partition 15 .

[0050] Ginseng Figure 7 The second partition 152 is higher than the first partition 151, so that the liquid storage chamber 121 has a deeper depth and a larger volume, which can store more liquid, extend the use time, and avoid the increase in maintenance costs caused by frequent liquid addition.

The fluid can quickly enter the mixing chamber 111 and the liquid can be used up as much as possible to prevent the situation where there is residual liquid and the liquid cannot be sprayed normally, thereby reducing maintenance costs.

This not only facilitates the assembly of the first connecting tube 31 and prevents the first connecting tube 31 from being entangled, but also allows the liquid in the liquid storage chamber 121 to flow smoothly through the first connecting tube 31, and also prevents the first connecting tube 31 from being damaged at the bend, thereby extending the service life of the first connecting tube 31.
