Description

Jet assembly and cleaning system

[0001] The present application claims priority to the Chinese patent application No. 202410983106.1 filed on July 22, 2024, and entitled "A cleaning system", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of cleaning equipment, in particular to a jet assembly and a cleaning system. BACKGROUND

[0003] The sensing area of a vehicle sensor may be contaminated during use, especially when used outdoors or in harsh environments. The surface may be attached with water, mist, frost, mud, insects, etc., which may block the sensor sensing area, causing the camera image to be blurred, distorted, and glare, etc. If this type of sensor is used for automatic or assisted driving, it may even cause a safety accident. Therefore, the sensor needs to be cleaned regularly.

[0004] Currently, the cleaning solution for vehicle sensors mainly uses a cleaning device installed at the sensor for cleaning. The cleaning device is provided with a nozzle, which cleans the sensor by spraying cleaning liquid. A large amount of cleaning liquid is needed during the cleaning process, and after cleaning is completed, the cleaning liquid may remain on the surface of the sensor, forming an obstruction to the sensor, and also attaching dust to cause secondary pollution of the sensor. To reduce the amount of cleaning liquid used and avoid the attachment of cleaning liquid, some existing cleaning devices are also provided with a nozzle that can spray gas to assist in cleaning, reduce the amount of cleaning liquid used, and keep the surface of the sensor dry after cleaning with cleaning liquid.

[0005] Although the setting of the gas nozzle can reduce the amount of cleaning liquid used and avoid the attachment of cleaning liquid to some extent, it will result in too many accessories of the cleaning device, and the space occupancy rate is large, which causes trouble for the installation and layout of the cleaning device.

DETAILED DESCRIPTION

[0060] In order to facilitate the understanding of the present application, the present application will be described in more detail below. However, it should be understood that the present application can be implemented in many different forms and is not limited to the embodiments or examples described herein. On the contrary, the purpose of providing these embodiments or examples is to make the disclosure of the present application more thorough and comprehensive.

[0061] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the specification of the present application is only for the purpose of describing specific embodiments or examples and is not intended to limit the present application.

[0062] Based on the excessive use of cleaning fluid by the cleaning system of the vehicle sensor and other components in the related art and the problem of cleaning fluid adhesion during the cleaning process, some existing cleaning systems are also provided with a gas jet nozzle to assist cleaning, reduce the use of cleaning fluid, and keep the sensor surface dry after cleaning. However, the setting of the gas jet nozzle will cause the cleaning system to have too many accessories, which will cause problems for the spatial layout of the cleaning system on the vehicle.

[0063] To solve the above technical problems, the jet assembly and the cleaning system comprising the same are provided, the jet assembly integrates the gas nozzle and the liquid nozzle, thereby reducing the related accessories of the cleaning system and providing convenience for the layout of the cleaning system.

[0064] It should be noted that the jet assembly described in the present application is used for but not limited to cleaning of vehicle sensor lens, etc. For the convenience of description, in the present application, only the jet assembly applied to cleaning of vehicle sensor lens is taken as an example for description, and the principle of the jet assembly applied to cleaning of other components is substantially the same as that applied to cleaning of vehicle sensor lens, which is not described here.

[0065] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

[0066] In order to better understand the present application, the technical solutions of the present application will be described in detail below with reference to Figs. 1 to 10:

[0067] As shown in Figs. 1 and 2, the jet assembly 60 provided by the embodiments of the present application comprises a mixing body 10, a first valve body 20 and a second valve body 30. The mixing body 10 has a mixing flow channel 11, a first fluid channel 12, a second fluid channel 13 and an output channel 14 which are in communication with the mixing flow channel 11. The first fluid channel 12 is used to supply the first fluid, the second fluid or the mixed phase of the first fluid and the second fluid to the output mixing flow channel 11. The first valve body 20 is at least partially arranged in the first fluid channel 12 and is used to control the on-off of the first fluid channel 12. The second valve body 30 is connected to the second fluid channel 13 and is used to control the on-off of the second fluid channel 13.

[0068] For example, the first fluid can be in liquid phase or gas phase. When the first fluid is in liquid phase, the second fluid is in gas phase. When the first fluid is in gas phase, the second fluid is in liquid phase. Of course, the first fluid and the second fluid can be in gas phase or liquid phase at the same time. The embodiments are described with the first fluid in liquid phase and the second fluid in gas phase.

[0069] Specifically, the jet assembly 60 comprises the mixing body 10, the first valve body 20 and the second valve body 30, the mixing body 10 has the mixing flow channel 11, the first fluid channel 12, the second fluid channel 13 and the output channel 14 which are in communication with the mixing flow channel 11, the first valve body 20 and the second valve body 30 are respectively arranged in the first fluid channel 12 and the second fluid channel 13, the first fluid channel 12 and the second fluid channel 13 can be controlled to be in the on or off state, the first fluid channel 12 and the second fluid channel 13 can be respectively connected to the liquid supply device and the gas supply device, when the first fluid channel 12 is in the on state, the liquid supplied by the liquid supply device enters the mixing flow channel 11 and is finally output from the mixing flow channel 11, when the second fluid channel 13 is in the on state, the gas supplied by the liquid supply device enters the mixing flow channel 11 and is finally output from the mixing flow channel 11, when the first fluid channel 12 and the second fluid channel 13 are in the on state, the gas and the liquid are mixed into the mixing flow channel 11 and are finally output from the mixing flow channel 11, thereby the use amount of the cleaning liquid can be reduced by the auxiliary cleaning of the gas, and the surface of the cleaned component can be kept dry by the spraying of the gas. Through the above arrangement of the jet assembly 60, the gas nozzle and the liquid nozzle can be integrated in the mixing body, thereby the volume of the cleaning system can be reduced and the layout difficulty of the cleaning system can be reduced.

[0070] In the embodiment, in order to form a jet flow from the mixing flow channel 11, the jet assembly 60 further comprises the nozzle 40 which is connected to the output channel 14 and is used to spray the first fluid, the second fluid or the mixed phase of the first fluid and the second fluid which are output through the output channel 14.

[0071] The embodiment can also switch different cleaning modes according to different cleaning scenes. For example, a single liquid flow mode, a single gas flow mode or a mixed flow mode.

[0072] In the single liquid flow mode, the first valve body 20 controls the first fluid channel 12 to be in the on state, the second valve body 30 controls the second fluid channel 13 to be in the off state, so that the nozzle 40 only sprays the liquid to clean the surface of the sensor, after cleaning, the first valve body 20 controls the first fluid channel 12 to be in the off state, the second valve body 30 controls the second fluid channel 13 to be in the on state, so that the nozzle 40 sprays the dry gas again to clean the residual liquid on the surface of the sensor.

[0073] In the single gas flow mode, the first valve body 20 controls the first fluid channel 12 to be in the off state, the second valve body 30 controls the second fluid channel 13 to be in the on state, so that the nozzle 40 only sprays the dry gas to clean the surface of the sensor, mainly to clean the dust, water droplets and other pollutants on the surface of the sensor.

[0074] In the mixed flow mode, the first valve body 20 controls the first fluid passage 12 to be in the off state, and the second valve body 30 controls the second fluid passage 13 to be in the connected state, so that the gas and the liquid enter the mixed flow channel 11 at the same time and are mixed, and finally are sprayed out from the nozzle 40 at the same time to form an atomized cleaning liquid to clean the dust, mud, insect corpses and other solid dirt on the surface of the sensor.

[0075] In the embodiment, the mixed flow channel 11 is arranged at an angle with the first fluid passage 12, and the angle between the medium output direction of the first fluid passage 12 and the medium flow direction of the mixed flow channel 11 is 90°-135°. Through this arrangement, the impact of the high-pressure gas on the first valve body 20 when entering the mixed flow channel 11 can be effectively reduced, thereby protecting the first valve body 20 and prolonging the service life of the jet assembly 60.

[0076] In the embodiment, the inner diameter of the output passage 14 is smaller than the inner diameter of the mixed flow channel 11, so as to improve the output pressure of the medium.

[0077] In the embodiment, the first valve body can be a one-way check valve or a solenoid valve. It is mainly used to control the on-off of the first fluid passage 12 and prevent the second fluid from entering the first fluid passage 12 in the reverse direction.

[0078] In the embodiment, the second valve body can be a one-way check valve or a solenoid valve. It is mainly used to control the on-off of the second fluid passage 12 and prevent the first fluid from entering the first fluid passage 12 in the reverse direction.

[0079] In some embodiments, as shown in FIG. 2, the first valve body 20 includes a mounting portion 21, a protruding portion 22 and an opening and closing control member 23. The mounting portion 21 is arranged on the first fluid passage 12 and has a first fluid flow channel 211. The protruding portion 22 is arranged at one end of the mounting portion 21 close to the mixed flow channel 11, and has a liquid outlet structure 221. The opening and closing control member 23 is connected to the protruding portion 22 and has a first state and a second state. In the first state, the opening and closing control member 23 blocks the liquid outlet structure 221, and in the second state, the opening and closing control member 23 opens the liquid outlet structure 221.

[0080] Specifically, the protruding portion 22 is in a columnar shape, the liquid outlet structure 221 is arranged on the side surface or the end surface of the protruding portion 22, and the opening and closing control member 23 is connected to the protruding portion 22 and blocks the liquid outlet structure 221 of the protruding portion 22 in the first state, so as to realize the off state of the first fluid passage 12 and prevent the first fluid from entering the mixed flow channel 11. In the second state, the opening and closing control member 23 opens the liquid outlet structure 221 of the protruding portion 22, so as to realize the on state of the first fluid passage 12 and make the first fluid enter the mixed flow channel 11.

[0081] In the embodiment, the protruding portion 22 extends coaxially with the mounting portion 21. Specifically, by this arrangement, it can be ensured that the fluid flowing out of the first fluid passage 12 through the mounting portion 21 can flow smoothly into the protruding portion 22, and finally can flow out through the fluid outlet structure, reducing the resistance of the fluid in the process of conveying.

[0082] In the embodiment, the opening and closing control member 23 comprises an elastic sleeve, which is sleeved on the protruding portion 22 and tightly fits with the fluid outlet structure 221, so as to block the fluid outlet structure 221 in the first state and make the liquid flow out of the gap between the opening and closing control member 23 and the fluid outlet structure 221 in the second state. The opening and closing control member 23 expands in the direction away from the side surface or end surface of the protruding portion 22 in the second state, so that a gap is formed between the inner wall of the opening and closing control member 23 and the side surface or end surface of the protruding portion 22, and the opening and closing control member 23 is a valve port of the first valve body 20. The opening and closing control member 23 is an opening and closing switch of the valve port, which can open the valve port under the pressure on the inside and tightly close the valve port when the pressure is on the outside, so as to avoid the gas in the mixed flow passage 11 from entering the first valve body 20 from the valve port in the reverse direction, and achieve the non-return effect.

[0083] Through the non-return effect of the first valve body 20, the output amount of the liquid can be accurately controlled. The specific process is as follows: after the liquid passes through the first fluid flow passage 211, under the high-pressure impact of the liquid, the liquid flows out along the fluid outlet structure 221, and the elastic sleeve is expanded to the second state. In the second state, a gap is formed between the elastic sleeve and the non-return valve fluid outlet structure 221, so that the liquid flows out of the gap and enters the mixed flow passage 11. When the liquid supply device stops supplying liquid, the pressure in the first fluid flow passage 211 decreases, and the elastic sleeve returns to the first state and tightly fits with the fluid outlet structure 221 to seal the non-return valve fluid outlet structure 221, so that the liquid in the mixed flow passage 11 cannot flow back to the non-return valve first fluid passage 12.

[0084] It can be understood that the mounting portion 21 can be fixed to the first fluid flow passage 211 by any method such as clamping, threaded connection or interference fit, and only needs to achieve partial blocking of the first fluid flow passage 211.

[0085] It can be understood that the elastic sleeve can be made of any material that can deform radially under the action of internal water pressure, for example, the elastic sleeve can be made of silicone or rubber material.

[0086] In some embodiments, as shown in FIGS. 3 and 4, the fluid outlet structure 221 comprises at least one through hole 2211 arranged on the protruding portion 22. Specifically, by arranging the fluid outlet structure 221 in the form of the through hole 2211, the liquid can be output from the first valve body 20 while avoiding damage to the opening and closing control member 23 under the action of external air pressure.

[0087] In the embodiment, when the through holes 2211 are multiple, the adjacent through holes 2211 have a reinforcing structure. The reinforcing structure can be arranged between the adjacent two through holes 2211 to improve the pressure bearing capacity of the protruding part 22 at the liquid outlet structure 221, so as to meet the pressure requirement of the liquid.

[0088] In some embodiments, as shown in FIGS. 3 and 4, the liquid outlet structure 221 further includes a groove 2212 arranged along the circumference of the protruding part 22, and the through hole 2211 is arranged in the groove 2212. Specifically, the groove 2212 is arranged to form a cavity structure between the opening and closing control member 23 and the liquid outlet structure 221. When the liquid fills the groove 2212, an acting force acting on the circumferential direction of the opening and closing control member 23 is formed, so that the opening and closing control member 23 is uniformly expanded outward, so that the liquid output from between the opening and closing control member 23 and the protruding part 22 is kept uniform, and meanwhile, the groove can also play a role of drainage, avoiding the blockage of the through hole 2211 on the liquid outlet structure 221 of the check valve, thereby improving the liquid outlet efficiency of the liquid outlet structure 221 and the service life of the first valve body 20.

[0089] In some embodiments, as shown in FIG. 3, the first fluid channel 12 is provided with a limiting wall 121 located on the side of the mounting part 21 close to the mixing flow channel 11 and opposite to the mounting part 21. The opening and closing control member 23 includes a sleeving part 231 and an axial limiting part 232. The sleeving part 231 is sleeved on the protruding part 22, and the axial limiting part 232 is connected to the sleeving part 231 and located between the mounting part 21 and the limiting wall 121 to limit the axial movement of the opening and closing control member 23. Specifically, the axial limiting part 232 is arranged between the mounting part 21 and the limiting wall 121, and the two sides of the axial limiting part 232 are limited by the mounting part 21 and the limiting wall 121, so that the axial movement of the opening and closing control member 23 is avoided, and the stability of the opening and closing control member 23 in the axial direction is ensured.

[0090] In the embodiment, the axial limiting part 232 extends towards the circumferential direction of the elastic sleeve.

[0091] In some embodiments, the first valve body 20 includes a hydraulic elastic reset ball valve (not labeled in the figure) arranged in the first fluid channel. The hydraulic elastic reset ball valve includes an elastic member and a ball valve. The elastic member is connected to the ball valve to drive the ball valve to block the liquid outlet 16 of the first fluid channel 211. Specifically, in the natural state, the ball valve blocks the liquid outlet 16 of the first fluid channel 211 in the limited state of the elastic member. When the ball valve bears a certain hydraulic pressure, the ball valve will be separated from the liquid outlet 16 of the first fluid channel 211 by overcoming the elastic force of the elastic member. Therefore, the opening and closing of the first fluid channel 211 can be realized by controlling the first fluid pressure.

[0092] In the embodiment, the elastic member can be a spring, a spring or an elastic accumulator. When the hydraulic pressure in the first fluid passage 211 is greater than the deformation force of the elastic member, the first fluid pushes the ball, the ball extrudes the elastic member, so that the elastic member is compressed, and a gap is formed between the liquid outlet 16 of the first fluid passage 211 and the ball for liquid flow; on the contrary, when the hydraulic pressure in the first fluid passage is less than the deformation force of the elastic member, the ball is pushed against the liquid outlet 16 of the first fluid passage 211 under the elastic force of the elastic member, suitable for plugging the liquid outlet 16.

[0093] In some embodiments, as shown in FIG. 3, the sleeve part 231 includes a radial limiting section 2311 and a deformation section 2312. The radial limiting section 2311 is located on the side of the liquid outlet structure 221 away from the mixing flow channel 11 and is attached to the side wall of the first fluid passage 12. The deformation section 2312 is connected to the radial limiting section 2311 and is spaced apart from the side wall of the first fluid passage 12. The deformation section 2312 blocks the liquid outlet structure 221 in the first state and allows liquid to flow from the gap between the opening and closing control member 23 and the liquid outlet structure 221 in the second state.

[0094] Specifically, the deformation section 2312 is arranged on the liquid outlet structure 221 and is spaced apart from the side wall of the first fluid passage 12. When the inner side of the deformation section 2312 is subjected to liquid pressure, it will expand radially outward. The radial limiting section 2311 is attached to the side wall of the first fluid passage 12, and its radial direction will be limited by the side wall of the first fluid passage 12, so that it will not be deformed, so that the liquid will only be output in the direction away from the radial limiting section 2311, thereby ensuring the sealing performance of the part of the opening and closing control member 23 away from the mixing flow channel 11.

[0095] In some embodiments, as shown in FIG. 4, the first valve body 20 further includes a liquid inlet connector 24 connected to the side of the mounting portion 21 away from the protruding portion 22. The liquid inlet connector 24 is used for connecting the liquid supply device, and the first fluid flow channel 211 penetrates through the liquid inlet connector 24. Specifically, the mounting portion 21 forms the liquid inlet connector 24, so that the liquid supply device only needs to be connected to the first valve body 20 to realize the connection with the first fluid passage 12, thereby eliminating the need to separately provide a connector member for the liquid supply device to connect to the first fluid passage 12, thereby simplifying the structure of the fluid jet assembly 60.

[0096] In some embodiments, as shown in FIG. 2, the connection between the second fluid channel 13 and the mixing flow channel 11 forms a fluid inlet 131, and the second valve body 30 includes a valve body 31 and a valve core 32, the valve body 31 is arranged on the mixing body 10 and located at one side of the fluid inlet 131, and the valve core 32 is adapted to move towards or away from the fluid inlet 131 relative to the valve body 31 to block or open the fluid inlet 131. Specifically, by controlling the extension and retraction of the valve core 32, the valve body 31 can control the opening and closing of the fluid inlet 131, thereby controlling whether the gas enters the mixing flow channel 11. In addition, by controlling the extension and retraction amount of the valve core 32, the valve body 31 can also adjust the size of the fluid inlet 131, thereby adjusting the amount of gas entering.

[0097] It can be understood that the valve body 31 can be arranged on the surface of the mixing body 10. When it is arranged on the surface of the mixing body 10, the valve body 31 is located at the end of the second fluid channel 13 (as shown in FIG. 2). The valve body 31 can also be arranged wholly or partially in the second fluid channel 13 of the mixing body 10. When it is arranged wholly or partially in the second fluid channel 13 of the mixing body 10, the valve body 31 can be connected with the second fluid channel 13 in the form of threaded connection, interference fit or clamping, etc.

[0098] It can be understood that the valve body 31 can be any driving component capable of driving the valve core 32 to move axially. In the present embodiment, the valve body 31 and the valve core 32 combine to form an electromagnetic valve structure.

[0099] In some embodiments, as shown in FIG. 2, the end of the valve core 32 close to the second fluid channel 13 is provided with an elastic sealing member 321, which can block or open the fluid inlet 131 by moving the valve core 32 towards or away from the fluid inlet 131. Specifically, the elastic sealing member 321 can ensure that the valve core 32 can better seal the fluid inlet 131, and can buffer the force acting on the valve core 32 and the fluid inlet 131, thereby avoiding deformation of the valve core 32 and the mixing body 10.

[0100] In the present embodiment, the elastic sealing member 321 can be a component with elastic properties such as a rubber pad or a silicone rubber pad, etc.

[0101] In some embodiments, the valve body 31 is threadedly connected to the second fluid channel 13 to achieve connection with the mixing body. Specifically, by threadedly connecting the valve body 31 with the second fluid channel 13, the valve body 31 can be fixed with the second fluid channel 13 while achieving sealing of the second fluid channel 13, thereby eliminating the need for a special sealing structure for sealing, effectively simplifying the structure of the fluidic assembly 60.

[0102] It can be understood that the valve body 31 can also be fixed to the mixing body 10 by any form such as clamping, interference fit, bolt fixation, etc., as long as the partial plugging of the second fluid channel 13 is achieved.

[0103] In some embodiments, as shown in FIG. 2, the mixing body 10 is also provided with a joint mounting port 15 which communicates with the second fluid channel 13, and the jet assembly 60 further comprises an air inlet joint 50 which is mounted in the joint mounting port 15 and is used for connecting the gas supply device. Specifically, the air inlet joint 50 can be connected with the gas supply device, so that the gas supply device can supply gas into the second fluid channel 13.

[0104] Through the above-mentioned arrangement of the second valve body 30 and the first valve body 20, the single liquid flow mode, the single gas flow mode and the mixed flow mode of the multiple output modes of the present embodiment can be realized through the following operation.

[0105] In the single liquid flow mode, the valve core 32 of the second valve body 30 abuts against the fluid inlet port 131, the mixed flow passage 11 is not in communication with the second fluid channel 13, the liquid supply device continuously outputs a large amount of liquid to the mixed flow passage 11 through the first valve body 20, the liquid enters the nozzle 40 through the output channel 14, and finally is sprayed out of the nozzle 40 to clean the sensor with liquid. Then, the valve core 32 of the second valve body 30 is away from the fluid inlet port 131, the gas supply device supplies gas to the gas supply channel, and the gas enters the nozzle 40 through the output channel 14, and finally is sprayed out of the nozzle 40 to dry the sensor.

[0106] In the single gas flow mode, the second valve body 30 is opened, the valve core 32 of the second valve body 30 is away from the fluid inlet port 131, the mixed flow passage 11 is in communication with the second fluid channel 13, the liquid source does not supply liquid, the gas supply device continuously outputs gas through the gas supply channel, the gas enters the nozzle 40 through the output channel 14, and finally is sprayed out of the nozzle 40 to clean the sensor with gas.

[0107] In the mixed flow mode, first, the second valve body 30 is closed, the valve core 32 of the second valve body 30 abuts against the fluid inlet port 131, the mixed flow passage 11 is not in communication with the second fluid channel 13, and the liquid supply device outputs a small amount of liquid to the mixed flow passage 11 through the first valve body 20. At the same time, the gas supply device outputs gas through the gas supply channel, and the gas is temporarily stored in the second fluid channel 13

[0108] Then, the valve core 32 of the second valve body 30 is away from the fluid inlet 131, so that the mixing flow channel 11 is communicated with the second fluid channel 13, and the gas enters the mixing flow channel 11 from the second fluid channel 13. Under the high pressure impact of the gas, the liquid is broken into small droplets, and after being fully mixed with the gas in the mixing flow channel 11, the liquid enters the output channel 14 and is finally sprayed out of the nozzle 40 to achieve the purpose of decontamination of the component to be decontaminated. By controlling the liquid single output amount of the first valve body 20, the size of the small droplets formed by mixing the liquid and the gas can be controlled.

[0109] In some embodiments, as shown in FIGS. 1, 2, 5, 6 and 7, the nozzle 40 includes a jet body 41 and a connecting pipe 42. The jet body 41 is provided with a fluid storage cavity 411 and a jet gap 412. One end of the jet gap 412 is communicated with the fluid storage cavity 411, and the other end of the jet gap 412 extends to the surface of the jet body 41 and forms a jet port 415. One end of the connecting pipe 42 is connected with the output channel 14, and the other end of the connecting pipe 42 is fixed to the jet body 41 and communicated with the fluid storage cavity 411. Specifically, the medium output from the output channel 14 will enter the connecting pipe 42, then enter the fluid storage cavity 411 through the connecting pipe 42, and finally enter the jet gap 412 to form a jet through the jet port 415 formed by the jet gap 412, thereby achieving the cleaning of the sensor.

[0110] In some embodiments, as shown in FIG. 8, the jet gap 412 includes an inlet section 4121 and an outlet section 4122. The inlet section 4121 is communicated with the fluid storage cavity 411, and the outlet section 4122 is communicated with the inlet section 4121 and forms a necked portion 4123 at the communication position with the inlet section 4121. The caliber of the necked portion 4123 is smaller than that of the inlet section 4121 and the outlet section 4122. Specifically, the medium first passes through the inlet section 4121, then enters the outlet section 4122, and finally is sprayed out of the outlet section 4122. Since the necked portion 4123 is formed at the connection position of the inlet section 4121 and the outlet section 4122, and the caliber of the necked portion 4123 is smaller than that of the inlet section 4121 and the outlet section 4122, the medium can be pressurized before entering the necked portion 4123, and then released after entering the outlet section 4122, thereby significantly improving the pressure of the medium sprayed by the nozzle 40, and thus improving the cleaning effect.

[0111] In some embodiments, as shown in FIG. 7, the outlet section 4122 is configured with a diverging portion 4124. Specifically, the caliber of the diverging portion 4124 gradually increases. By providing the diverging portion 4124 in the outlet section 4122, the spraying range of the fluid output from the necked portion 4123 will gradually increase, thereby increasing the cleaning range of the nozzle.

[0112] In some embodiments, as shown in FIG. 8, the jet body 41 encloses a cavity 4125 for accommodating the component to be cleaned, and the jet port 415 is arranged at the edge of the cavity 4125. Specifically, the jet body provides protection for the sensor to be cleaned by enclosing the sensor, thereby improving the cleaning effect.

[0113] In the embodiment, as shown in FIG. 8, the jet body 41 is circular in shape, and the jet port 415 of the jet body 41 is arc-shaped. When the jet port 415 is used for jetting, a fan-shaped surface fluid can be jetted out.

[0114] In some embodiments, as shown in FIG. 9, the jet body 41 includes a jetting portion 413 and a fixing portion 414. The fluid storage cavity 411 and the jet gap 412 are arranged in the jetting portion 413, and the divergent port 4124 extends to the end surface of the jetting portion 413. The fixing portion 414 is arranged at an angle with the jetting portion 413. Specifically, the fixing portion 414 can be used for mounting and fixing the jet body 41 on the side of the sensor to be cleaned. The jetting portion 413 is used for receiving the medium by forming the fluid storage cavity 411 and the jet gap 412, and jetting the medium. This structure can significantly reduce the volume of the jet body 41, and provide convenience for the installation and layout of the jet body 41.

[0115] The embodiment of the present application also provides a cleaning system, as shown in FIGS. 10 and 11, which includes a jet assembly 60, a first pump set 70 and a second pump set 80. The first pump set 70 is connected with the first fluid channel 12, and is used for supplying liquid into the first fluid channel 12. The second pump set 80 is connected with the second fluid channel 13, and is used for supplying gas into the second fluid channel 13.

[0116] Specifically, the first pump set 70 and the second pump set 80 are respectively connected with the first fluid channel 12 and the second fluid channel 13. When the first fluid channel 12 is conducted, the liquid supplied by the first pump set 70 enters the mixed flow channel 11, and is finally jetted out from the nozzle 40. When the second fluid channel 13 is conducted, the gas supplied by the first pump set 70 enters the mixed flow channel 11, and is finally jetted out from the nozzle 40. When the first fluid channel 12 and the second fluid channel 13 are simultaneously conducted, the gas and the liquid are mixed into the mixed flow channel 11, and are finally jetted out from the nozzle 40. In this way, the use amount of the cleaning liquid can be reduced by the auxiliary cleaning of the gas, and the surface of the component to be cleaned can be kept dry by the jetting of the gas. Through the above arrangement of the jet assembly 60, the gas nozzle 40 and the liquid nozzle 40 can be integrated in the jet assembly 60, thereby reducing the volume of the cleaning system and the difficulty of the layout of the cleaning system.

[0117] In some embodiments, the first pump group 70 includes a water pump and a liquid storage pot, the water pump and the liquid storage pot are in communication, the liquid storage pot is connected with the liquid inlet connector 24, and the output of the liquid storage pot is liquid. The second pump group 80 includes an air pump, an air storage tank, and an air compressor, the air pump and the air storage tank are in communication, the air storage tank is connected with the air inlet connector 50, the output of the air storage tank is gas, and the air compressor is connected with the jet assembly 60 and supplies compressed gas to the jet assembly 60.

[0118] In some embodiments, the cleaning system further includes a cleaning assembly, as shown in FIG. 10, the cleaning assembly includes a cleaning system controller 90, and the cleaning system controller 90 is electrically connected with the liquid storage pot through a signal circuit. Specifically, the cleaning system controller 90 refers to a controller hardware, which can control the operation of the air circuit, the water circuit, and the electrical elements in the cleaning system such as the air pump, the water pump, and the electromagnetic valve through the circuit. The cleaning system controller 90 is electrically connected with and controls the air circuit, the water circuit, the circuit, and the signal circuit. The cleaning system controller 90 is electrically connected with the liquid storage pot through the signal circuit, and the signal is a liquid level sensor. When the liquid level is lower than a threshold value, the controller receives the signal change of the liquid level sensor and makes an alarm for supplementing the cleaning liquid. The cleaning system controller 90 is connected with the second pump group 80, the first valve body 20, the second valve body 30, and the first pump group 70 through the circuit.

[0119] In this embodiment, the cleaning system controller 90 is an automotive electronic control unit ECU (Electronic Control Unit) or a body control module BCM (Body Control Module).

[0120] In some embodiments, as shown in FIG. 10, the cleaning assembly further includes an intelligent driving controller and a rain sensor 100, the rain sensor 100 is arranged on one side of the component to be cleaned and is electrically connected with the intelligent driving controller, the intelligent driving controller is used to control the water spraying action of the jet assembly 60 through the rainwater amount sensed by the rain sensor 100, the second pump group 80, the first pump group 70, the first valve body 20, and the second valve body 30 are all used to control the water spraying action of the jet assembly 60 through the cleaning system controller 90, and the rain sensor 100 is used to control the water spraying action of the jet assembly 60 through the intelligent driving controller.

[0121] In some embodiments, after the cleaning assembly is powered on, the cleaning controller will perform a self-check and check the status of each peripheral device. After everything is in order, the cleaning controller will check whether the air pressure in the air path is within the preset range (generally between 2-10 bar, but there may be differences depending on the system and sensor requirements). If the air pressure is insufficient, the air pump will be driven to supplement the system air pressure. When the air pressure reaches the preset upper limit, the air pump will stop working. At this time, the air path system will store the pressure gas in the second fluid channel 13 (in some systems, the nozzle 40 has a large gas consumption, and in order to reduce the working frequency of the air pump and stabilize the air pressure, etc., the pressure gas is stored in the second fluid channel 13). The pre-stored pressure gas can trigger the cleaning action at any time, achieving the purpose of fast response. When the gas reaches the preset pressure range, the cleaning can receive the trigger signal and execute the cleaning action according to the cleaning requirements.

[0122] A. When the cleaning controller receives a cleaning instruction, if the cleaning object is liquid or floating dust (with weak adhesion), the second valve body 30 is powered on and opened to allow compressed gas to enter the mixed flow passage 11 directly. Due to the one-way conduction characteristic of the first valve body 20, compressed gas cannot enter the water path and cause gas leakage and reverse flow of cleaning liquid back to the liquid storage pot. During the process, compressed gas can only accelerate through the mixed flow passage 11 and become a high-speed gas flow, which is sprayed from the nozzle 40 to clean the sensor.

[0123] During the process, multiple intermittent point jet gas flows can be formed by controlling the opening and closing of the second valve body 30 multiple times, achieving more effective blowing away of liquid droplets or floating dust and completing the cleaning action. At this time, by adjusting different power-on parameters, different effects can be achieved, such as fast on-off 3 times (power-on 0.02 ms, power-off 0.2 ms, cycle 3 times), which can achieve fast removal of water droplets and floating dust on the surface of the sensor; or continuous intermittent on-off (on 0.02 s, off 0.48 s, continuous cycle), which can achieve a cleaning effect similar to that of a wiper that brushes 0.5 s each time, which can effectively deal with the scenario of rainwater continuously hitting the sensor in rainy weather. By using intermittent high-speed gas flow, 80% of compressed gas consumption can be reduced under the condition of effective cleaning each time, which is more energy-efficient. At the same time, compared with the traditional water cleaning scheme, this process does not consume cleaning liquid.

[0124] B. If the cleaning object is mud stains, grease, bird droppings, insect carcasses, etc. (with strong adhesion), cleaning liquid is needed during the cleaning process. The water pump can be powered on for a short time first (such as 0.5 s of continuous power supply and then power-off), the cleaning liquid breaks through the opening pressure of the first valve body 20, enters the mixed flow passage 11, and then the second valve body 30 is powered on for a short time several times (such as power-on 0.02 s, power-off 0.3 s, cycle 2 times) and opened, and compressed gas enters the jet assembly 60. At this time, the first valve body 20 has been closed, the gas and the cleaning liquid are mixed, accelerated through the mixed flow passage 11, and become a high-speed gas flow containing cleaning liquid droplets, which clean the sensor.

[0125] The above process can be repeated several times in the process, after the stubborn dirt is washed away, the second valve body 30 is powered for a short time several times (such as 0.02s power on, 0.2s power off, 3 times), the second valve body 30 is opened, the compressed gas enters the jet assembly 60, at this time the cleaning liquid in the first cavity 14 has been sprayed out with the previous several times of air injection, the compressed gas becomes dry high-speed airflow after acceleration through the mixing channel 11 and washes the residual dirt or cleaning liquid of the sensor, after cleaning, the surface of the sensor is clean and dry, and the cleaning action is completed. Compared with the traditional water injection cleaning scheme, the water consumption is reduced by more than 95%, because the cleaning liquid does not need to fill the mixing channel 11 in the jet assembly 60 to establish enough water injection pressure, during the acceleration of the compressed gas, liquid droplets will be impacted into small liquid droplets, uniformly distributed in the high-speed airflow, and small liquid droplets are more easily accelerated to a higher speed, achieving better washing effect, and after cleaning, the residual cleaning liquid can also be removed by the dry high-speed airflow, avoiding secondary pollution caused by the adsorption of residual cleaning liquid. Therefore, the present scheme can use lower cleaning liquid consumption to achieve better cleaning effect.

[0126] The technical features of the above-mentioned embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are all within the protection scope of the present application.
