In addition, the terms "first", "second", etc. in the application embodiments are only used for convenience of description, and cannot be understood as indicating or implying relative importance.
[0045] Referring to FIG. 1, a camera system according to an embodiment of the present application includes a camera and a cleaning device 100. Figure 1 In the first embodiment, the camera system according to the embodiment of the present application includes a camera and a cleaning device 100. The cleaning device 100 includes a mixing cavity structure 11, a liquid storage tank 12, and a gas jet 2.
[0046] The mixing cavity structure 11 encloses a mixing cavity 111 provided with an outlet 1110, and a liquid inlet through hole 112 and a gas inlet through hole 113 communicating with the mixing cavity 111. The liquid storage tank 12 is provided with a liquid storage cavity 121 communicating with the mixing cavity 111, and sprays liquid into the mixing cavity 111 through the liquid inlet through hole 112. The gas jet 2 sprays gas into the mixing cavity 111 through the gas inlet through hole 113. The distance between the liquid inlet through hole 112 and the outlet 1110 is less than the distance between the gas inlet through hole 113 and the outlet 1110. The cleaning device 100 flushes the dirt and foreign matter by the gas-liquid mixture sprayed into the mixing cavity 111, and more effectively cleans the object to be cleaned, with better cleaning effect.
[0047] The cleaning device 100 of the embodiments of the present application can be applied to products that need to be cleaned, such as lenses, sensors, etc. on a car, and the application scenarios of the cleaning device 100 are not limited by the present application. The liquid stored in the liquid storage cavity 121 can be water, cleaning liquid, or a mixture of water and cleaning liquid, and the type of the liquid is not limited by the present application.
[0048] In some embodiments, the air jet 2 can be a gas pump or a container containing gas, and the type of the air jet 2 is not limited by the present application as long as it can jet air into the mixing cavity 111.
[0049] In some embodiments, the mixing cavity 111 extends along a first direction D1, the liquid inlet through hole 112 and the air inlet through hole 113 both extend along a second direction D2, the liquid inlet through hole 112 is in communication with the liquid storage tank 12, the first direction and the second direction form an included angle, and the axis of the liquid inlet through hole 112 and the axis of the air inlet through hole 113 have a gap. In some embodiments, the first direction D1 is perpendicular to the second direction D2, and the angle of the included angle between the first direction D1 and the second direction D2 is not limited by the present application.
[0050] Figures 2 to 20 The cleaning device 100 of the second embodiment of the present application is shown in FIG. 2. The cleaning device 100 includes a housing 1, and the housing 1 encloses a mixing cavity 111. Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in FIG. 2, the cleaning device 100 of the second embodiment includes a housing 1, and the housing 1 encloses a mixing cavity 111. The liquid storage tank 12 is part of the housing 1. The cleaning device 100 includes a communication pipe 3 that is in communication with the liquid storage cavity 121 and the mixing cavity 111, and the fluid in the liquid storage cavity 121 flows through the communication pipe 3 into the mixing cavity 111.
[0051] The housing 1 is also provided with a gas storage cavity 114, and at least part of the communication pipe 3 is located in the gas storage cavity 114. When the gas pressure in the gas storage cavity 114 changes, the communication pipe 3 is extruded to jet liquid into the mixing cavity 111. In order to control the amount of liquid, the communication pipe 3 is extruded by using the gas storage process of high-pressure gas, and the amount of liquid extruded is the volume of the communication pipe 3 after deformation. The amount of liquid is controlled by using the way of extruding the communication pipe 3 by high-pressure gas, which realizes the function of extremely small amount of liquid and effectively reduces the additional maintenance work such as manually adding liquid.
[0052] In some embodiments, when the gas storage cavity 114 is inflated and pressurized, the liquid in the communication pipe 3 is squeezed into the mixing cavity 111, and when gas is supplied into the mixing cavity 111, the gas disperses the small liquid droplets into a water mist, forming a gas-liquid mixture that is sprayed out of the outlet 1110. The cleaning device 100 uses a liquid-gas combination to form a gas-liquid mixture with a small amount of liquid, which is used to clean the object under high pressure. The liquid is infiltrated to reduce adhesion, and the high-pressure gas is blown away to improve cleaning effect.
[0053] In some embodiments, the outlet 1110 can be connected to a pipe or various nozzles of appropriate length to clean the object more effectively, which is not limited in the present application.
[0054] In some embodiments, the communication pipe 3 in the gas storage cavity 114 is a flexible pipe to facilitate deformation of the communication pipe 3 when it is squeezed by high-pressure gas, so that the mixing cavity 111 can normally spray liquid. The amount of liquid squeezed out is the volume of the flexible pipe after deformation. When the flexible pipe is squeezed and deformed by high-pressure gas, the volume inside the flexible pipe becomes smaller, and the amount of liquid squeezed out is equal to the volume reduction of the flexible pipe. Since the volume of the flexible pipe is small, the volume reduction is also small, and therefore the amount of liquid squeezed out is also small, thereby achieving the goal of providing a small amount of liquid. When it is necessary to adjust the liquid supply amount on demand, the length and cross-sectional size of the flexible pipe can be adjusted to achieve this goal.
[0055] In some embodiments, the liquid storage cavity 121 and the mixing cavity 111 can be directly connected, saving the communication pipe 3 and space. In some embodiments, the housing 1 encloses the liquid storage cavity 121, which is compact in structure and saves processing and assembly procedures.
[0056] Referring to Figure 4 , Figure 5 , Figure 6 and Figure 7 In some embodiments, the housing 1 includes a partition plate 15 and a first side wall 16 extending from the partition plate 15, and the partition plate 15 and the first side wall 16 enclose the gas storage cavity 114 and the liquid storage cavity 121. In some embodiments, the gas storage cavity 114 and the liquid storage cavity 121 have the same opening direction.
[0057] In some embodiments, the mixing cavity 111 is arranged on the partition plate 15. In some embodiments, the partition plate 15 includes a first partition plate 151 and a second partition plate 152, the first partition plate 151 and part of the first side wall 16 enclose the liquid storage cavity 121, the second partition plate 152 and part of the first side wall 16 enclose the gas storage cavity 114, and the mixing cavity 111 is arranged on the second partition plate 152.

[0058] Referring to Figure 7, the second partition 152 is higher than the first partition 151, so that the depth of the liquid storage cavity 121 is deeper and the volume is larger. It can store more liquid, extend the usage time, and avoid the increase in maintenance cost caused by frequent liquid addition.
[0059] Refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 , in some embodiments, the cleaning device 100 includes a first cover plate 41 fixed to the first side wall 16 and a seal 42 located between the first cover plate 41 and the first side wall 16 to seal the air storage cavity 114 and the liquid storage cavity 121.

The assembly hole 150 is close to the mixing cavity 111 to reduce the length of the connecting pipe 3 and also reduce the liquid flow path. The fluid can quickly enter the mixing cavity 111, and the liquid can be used up as much as possible, preventing the situation that there is still liquid remaining and normal liquid spraying cannot be carried out, and reducing the maintenance cost.
[0063] In some embodiments, the opposite ends of the first connecting pipe 31 are connected with a first joint 33 and a second joint 34; the opposite ends of the second connecting pipe 32 are connected with a third joint 35 and a fourth joint 36. The first joint

In some embodiments, the one-way valve 321 can also be arranged on one of the first joint 33, the second joint 34, the third joint 35 and the fourth joint 36; or, multiple one-way valves 321 are arranged on multiple of the first joint 33, the second joint 34, the third joint 35 and the fourth joint 36 respectively.
[0066] Referring to FIG. 1, the first communication pipe 31 is arranged in the liquid storage cavity 121, and the second communication pipe 32 is arranged in the mixing cavity 111.

Figure 11 In some embodiments, the first joint 33 is assembled into the flow-through hole 155 in the same direction as the second joint 34 assembled into the assembly hole 150, which not only facilitates the assembly of the first communication pipe 31 but also eliminates the winding of the first communication pipe 31, so that the liquid in the liquid storage cavity 121 flows smoothly through the first communication pipe 31 and the first communication pipe 31 is not damaged at the bending part, thereby prolonging the service life of the first communication pipe 31.

[0132] The non-water collecting portion 812 is fixed to the base 83. The non-water collecting portion 812 is provided with a second through hole 8121 for the fourth screw 840 to pass through. The plurality of second through holes 8121 are arranged at the corners of the non-water collecting portion 812.

[0135] In some embodiments, the base 83 is made of metal, which not only serves to support the condensing sheet 81 and the refrigerating sheet 82, but also forms the liquid storage tank 12 together with the shell 1. The heat dissipated by the base 83 can heat the liquid storage tank 12, preventing the water in the liquid storage tank 12 from freezing, and ensuring that the liquid can be sprayed normally, so as not to affect the normal operation of the cleaning device 100.
[0136] In some embodiments, the camera system comprises an anti-freezing liquid storage tank (not shown) which is in communication with the liquid storage tank 12 to add anti-freezing liquid into the liquid storage tank 12, preventing the water in the liquid storage tank 12 from freezing, and ensuring that the liquid can be sprayed normally, so as not to affect the normal operation of the cleaning device 100.

[0140] When the water pump 30 works once, it transports a small amount of liquid into the mixing cavity 111. When the control valve assembly 5 works once, it opens the gas supply path, and the high-pressure gas disperses the liquid in the mixing cavity 111 together to be sprayed out, forming a high-speed gas flow with water vapor, which can clean the dirty surface. The water pump 30 can accurately control the water supply, which can reduce the water consumption.

The fifth joint 391 and the sixth joint 392 are assembled to the partition plate 15 in a direction opposite to the depth direction of the liquid storage cavity 121.
[0143] Not only the third communication pipe 37 and the fourth communication pipe 38 are convenient to assemble, but also the third communication pipe 37 and the fourth communication pipe 38 have no winding phenomenon, which not only makes the liquid in the liquid storage cavity 121 flow smoothly through the third communication pipe 37 and the fourth communication pipe 38, but also avoids damage of the third communication pipe 37 and the fourth communication pipe 38 at the bending part, so as to prolong the service life of the third communication pipe 37 and the fourth communication pipe 38.
[0144] In some embodiments, the fifth joint 391 and the sixth joint 392 are threadedly connected with the partition plate 15. The fifth joint 391 and the sixth joint 392 are convenient to assemble and disassemble.
[0145] In some embodiments, one or more of the third communication pipe 37, the fourth communication pipe 38, the fifth joint 391 and the sixth joint 392 are provided with a one-way valve 321 to prevent water from flowing back.

[0147] The difference between the second embodiment and the first embodiment is that the liquid inlet through hole 112 and the gas inlet through hole 113 are located on the same side of the mixing cavity 111.
[0148] In some embodiments, the fifth joint 391 is a multi-way valve, a first end of the fifth joint 391 is in communication with the liquid storage tank 12, a second end of the fifth joint 391 is in communication with the third communication pipe 37, and a third end of the fifth joint 391 is in communication with the antifreeze storage tank.
