[0002] In fields such as automotive, security monitoring, and optical equipment, curved surface components (such as camera covers and rearview mirrors) are exposed to complex environments for extended periods, making their surfaces prone to accumulating dirt, rain stains, frost, and other contaminants. These contaminants not only affect the aesthetics of the equipment but also significantly reduce key performance indicators such as optical transmittance and signal transmission efficiency, necessitating the development of efficient decontamination solutions.

[0003] Traditional cleaning techniques have significant limitations: manual wiping is insufficient to thoroughly remove stubborn dirt from curved surfaces and corners, and may even cause surface scratches; while existing automatic cleaning systems mostly rely on high-pressure rotating nozzles, which not only require excessive cleaning fluid (resulting in resource waste), but also lead to uneven cleaning due to the mismatch between the jet angle and the curved surface, especially in areas with high curvature. Furthermore, existing cleaning devices struggle to adapt to surfaces with varying curvatures, failing to create a uniform surface fluid coverage, resulting in inconsistent cleaning performance.

[0047] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0049] In traditional curved surface cleaning systems, the fluid sprayed from high-pressure nozzles is distributed in a discrete point pattern, failing to form a continuous and uniform fluid coverage layer. Furthermore, the spiral jet trajectory generated by the high-pressure rotating nozzles can cause fluid coverage blind spots in high curvature areas, resulting in inconsistent cleaning effects.

[0050] For example, in the application scenario of vehicles equipped with vehicle-mounted millimeter-wave radar, the surface of the vehicle-mounted millimeter-wave radar protective cover will be contaminated with residual pollutants on the curved surface, forming an optical scattering layer and an electromagnetic interference source, which will increase the missing rate of lidar point cloud data and the false alarm rate of millimeter-wave radar. Long-term accumulation will lead to the drift of sensor calibration parameters, significantly increasing the safety risk factor of the vehicle.

[0051] Therefore, by changing the shape of the nozzle, the fluid can be ejected from a specific nozzle to form a continuously covering fluid layer.

[0052] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0053] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 This application discloses a jetting device, including a jetting body 1 and a cover plate 2. The jetting body 1 has a receiving cavity 11 and a jetting surface 12. A jetting hole 13 communicating with the receiving cavity 11 is opened on the jetting surface 12. The jetting surface 12 is the outer side of the side wall of the receiving cavity 11 near the jetting direction. The cover plate 2 is disposed on the jetting surface 12. A fluid ejection cavity 3 is formed between the cover plate 2 and the jetting surface 12. A slit ejection port 4 matching the surface to be cleaned is opened on the inner wall of the fluid ejection cavity 3.

[0054] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4The jet body 1 can be integrally molded from metal or engineering plastic. The receiving cavity 11 of the jet body 1 is used to store and distribute fluid. The jet hole 13 guides the fluid to the jet surface 12. The receiving cavity 11 forms a fluid channel through the jet hole 13. The jet hole 13 is a through hole that connects the jet surface 12 and the receiving cavity 11.

[0055] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 The cover plate 2 covers the jet surface 12. The cover plate 2 can be an arc-shaped metal plate or an injection molded part. It is installed on the jet body 1 and forms a fluid ejection cavity 3 between it and the jet surface 12.

[0056] Specifically, the fluid ejection cavity 3 between the cover plate 2 and the jet surface 12 is a flat cavity. The fluid ejection cavity 3 is used to merge multiple fluids ejected from the jet hole 13 into a continuous fluid layer. The flat design of the fluid ejection cavity 3 reduces the turbulence of the fluid in the fluid ejection cavity 3 and improves the stability of the jet.

[0057] The slit nozzle 4 is a slit structure that matches the end of the fluid ejection chamber 3 with the surface of the curved surface to be cleaned. The shape of the slit nozzle 4 can be an arc or a straight opening. The planar fluid layer ejected through the slit nozzle 4 achieves uniform cleaning of the curved surface structure, ensuring the consistency of the cleaning effect. In addition, the planar fluid reduces the amount of cleaning liquid used, improves resource utilization efficiency, and improves cleaning efficiency and quality.

[0058] It should be noted that the fluid is a cleaning solution, which can be a cleaning fluid for the corresponding equipment. For example, when cleaning a lidar, a special cleaning fluid for lidar is used.

[0059] During operation, the fluid first enters the receiving cavity 11 of the jet body 1, and then enters the jet surface 12 through the jet hole 13. The fluid ejection cavity 3 formed between the cover plate 2 and the jet surface 12 constrains and guides the fluid. The fluid is finally ejected from the slit nozzle 4 to form a surface fluid. The slit nozzle 4 matches the surface to be cleaned to ensure that the fluid evenly covers the surface to be cleaned.

[0060] Therefore, the jet device provided in this application, through the fluid ejection cavity 3 formed by the jet body 1 and the cover plate 2 and the slit ejection outlet 4, transforms the traditional point jet into a surface fluid output, enabling the fluid to cover the surface to be cleaned in a surface manner. It is especially suitable for curved surfaces, achieving uniform fluid coverage without cross-interference. This solves the problems of uneven fluid coverage, resource waste, and difficulty in cleaning curved dead corners in traditional cleaning technologies. It has the advantages of high efficiency in cleaning, high fluid utilization, and strong structural adaptability.

[0061] This application further proposes that the jet body 1 is arc-shaped along the length direction of the jet body 1, the cover plate 2 is an arc-shaped cover plate 2, the jet surface 12 is an arc-shaped surface with the same or similar curvature as the arc-shaped cover plate 2, and there is a gap between one side of the arc-shaped cover plate 2 and the jet surface 12, the gap forming a slit nozzle 4, thereby forming a continuous arc-shaped jet path.

[0062] It should be noted that the jet surface 12 is an arc surface with a similar curvature to the arc-shaped cover plate 2. The similar curvature means that the curvature difference between the jet surface 12 and the arc-shaped cover plate 2 is 0-5°.

[0063] Specifically, when the high-pressure fluid enters the receiving cavity 11, it enters the fluid ejection cavity 3 through the jet hole 13. Since the curvature of the jet surface 12 is the same as or similar to the curvature of the arc-shaped cover plate 2, the fluid is guided by the curved surface during the ejection process, covering the high curvature area along the tangential direction. The fluid diffuses evenly along the arc-shaped gap, forming a fan-shaped spray surface that matches the curvature of the surface to be cleaned.

[0064] For example, when cleaning the curved protective cover of a vehicle radar, the curvature of the slit nozzle 4 is consistent with the radius of curvature of the protective cover, and the fluid covers the entire surface in a laminar flow pattern that conforms to the curved surface, effectively removing dirt from the edges.

[0065] Furthermore, the arc-shaped cover plate 2 is detachably fixed to the jet body 1. The detachable arc-shaped cover plate 2 is designed to facilitate adjustment and maintenance, thereby enhancing the applicability and reliability of the device.

[0066] The width of the slit nozzle 4 can be controlled by adjusting the distance between the arc-shaped cover plate 2 and the jet surface 12. In some embodiments, the distance between the arc-shaped cover plate 2 and the jet surface 12 is in the range of 0.1 mm to 2 mm, which adjusts the distance and range of the fluid ejection cavity 3.

[0067] Through the above technical solution, this application achieves uniform decontamination of curved surfaces. The arc-shaped slit nozzle 4 can match the curved surface to be decontaminated, avoiding the decontamination dead angles caused by traditional point spraying. At the same time, the surface spraying reduces the amount of decontamination liquid used and improves the decontamination efficiency.

[0068] This application further proposes that the cover plate 2 has a recess 5 on the side opposite to the jet surface 12, which is recessed away from the jet surface 12. The inner wall of the recess 5 and part of the jet surface 12 form a fluid ejection cavity 3. The fluid ejection cavity 3 is a flat cavity. The curvature of the jet body 1 facing the surface to be cleaned is the same as or similar to the curvature of the surface to be cleaned.

[0069] Specifically, the jet body 1 matches the curvature of the surface to be cleaned, maintaining a constant gap between the slit nozzle 4 and the curved surface. The fluid covers the entire surface to be cleaned at a parallel or near-parallel angle. The fluid ejection chamber 3 is formed by the inner wall of the recess 5 and the jet surface 12. The height of the fluid ejection chamber 3 is determined by the depth of the recess 5 and is flat. The fluid forms a laminar flow state within the fluid ejection chamber 3. When it passes through the slit nozzle 4, the flow velocity increases, forming a continuous planar jet covering the curved surface. This eliminates the cleaning blind spots in high-curvature areas of traditional solutions and facilitates uniform fluid distribution within the chamber, thereby achieving planar jetting.

[0070] Furthermore, the curvature of the side of the jet body 1 facing the surface to be cleaned is the same as or similar to the curvature of the surface to be cleaned. Through the above technical solution, uniform distribution of fluid within the ejection chamber is achieved, ensuring a planar spray effect and guaranteeing that the cleaning liquid can evenly cover the entire surface to be cleaned, avoiding the generation of cleaning dead zones, and efficiently cleaning curved surface components, thus improving cleaning efficiency and quality.

[0071] This application further proposes that the diameter of the jet orifice 13 gradually increases along the jet direction of the fluid.

[0072] The jet orifice 13 adopts a gradually expanding channel structure, with its inner wall forming a continuously expanding flow channel cross-section, such as conical expansion or parabolic expansion. The expansion angle is controlled between 5° and 30° to balance the fluid velocity and diffusion range. The gradually expanding structure of the jet orifice 13 works in conjunction with the flat cavity of the fluid ejection chamber 3. The gradually expanding structure slows down the fluid velocity while expanding the coverage area, and combined with the flat cavity, it further constrains the fluid to form a planar distribution.

[0073] Specifically, after the fluid enters the jet hole 13, the coverage area of ​​the fluid increases as the hole diameter gradually increases. The gradually expanding structure of the jet hole 13 and the flat shape of the slit nozzle 4 make the fluid form a laminar flow state during the jetting process, uniformly covering the surface to be cleaned.

[0074] Through the above technical solution, this application can improve the stability and uniformity of fluid jets, making the ejected fluid present a more uniform planar distribution, which is beneficial for the comprehensive decontamination of curved structures, especially for the decontamination effect of high curvature areas.

[0075] This application further proposes that there are multiple jet holes 13, which are arranged at intervals along the length of the jet body 1, and the inner wall extension lines of two adjacent jet holes 13 intersect, so that the fluid ejected from two adjacent jet holes 13 cross and overlap to form a planar fluid.

[0076] Multiple jet holes 13 are arranged at intervals along the length of the jet body 1. The spacing between adjacent jet holes 13 is determined according to the fluid diffusion angle to ensure that the coverage areas of adjacent jets overlap. The arrangement of the intersecting extension lines of the inner walls of the jet holes 13 causes the fluid jet paths to intersect in space. The fluid momentum in the intersecting areas is superimposed to form a continuous and uniform planar fluid layer.

[0077] Specifically, the multiple jet holes 13 are arranged at intervals so that the fluid coverage area extends continuously along the length of the jet body 1. The fluids sprayed from adjacent jet holes 13 have overlapping areas, eliminating the decontamination blind spots between individual jet holes 13. The structural design of intersecting inner wall extension lines allows the fluids sprayed from different jet holes 13 to converge at a predetermined distance, improving the uniformity of the fluid layer thickness after convergence.

[0078] The jet holes 13 can be uniformly distributed along the length of the jet body 1. In one embodiment, a jet hole 13 is provided every 5 cm. The inner wall of each jet hole 13 is conical, so that the ejected fluid spreads in a fan shape. The extension lines of the inner walls of two adjacent jet holes 13 can intersect outside the jet hole 13, and the intersection point is about 2 cm away from the jet surface 12. This allows the two adjacent fluid streams to cross and overlap in the air when the fluid is ejected from the jet hole 13, forming a continuous planar fluid.

[0079] Through the above technical solution, by arranging multiple jet holes 13 at intervals along the length of the jet body 1, the entire length range of the surface to be cleaned can be covered. Moreover, the fluid ejected from adjacent jet holes 13 overlaps and intersects to form a planar fluid, achieving uniform cleaning of curved structures, avoiding the generation of cleaning dead zones, and improving the uniformity and efficiency of cleaning. At the same time, the formation of planar fluid reduces the pressure requirement of a single jet hole 13, lowers the requirements for the pump, and saves energy consumption. In addition, planar fluid can better adapt to curved structures and improve the cleaning effect on high curvature areas.

[0080] Reference Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11This application further proposes that the jet device also includes a delivery component, which includes a delivery pipe 6, a delivery connector 7, and a connecting plate 8. The delivery pipe 6 is externally connected to a fluid source and has a first delivery channel 61 inside. The delivery connector 7 has a second delivery channel 71 inside and is connected to the delivery pipe 6. The first delivery channel 61 and the second delivery channel 71 are sealed together. The delivery connector 7 is disposed on the connecting plate 8. The jet body 1 has an arc-shaped mounting groove 14. The connecting plate 8 has a first connection part 81 and a second connection part 82. The connecting plate 8 is provided with a delivery outlet 83 corresponding to the second delivery channel 71. The delivery outlet 83 is connected to the receiving cavity 11. The fluid enters the second delivery channel 71 of the delivery connector 7 from the delivery pipe 6 through the first delivery channel 61, and then enters the receiving cavity 11 of the jet body 1 through the delivery outlet 83 of the connecting plate 8.

[0081] The conveying pipe 6 and the conveying connector 7 achieve fluid transmission through a sealed connection of the first conveying channel 61 and the second conveying channel 71. Connecting part 1 81 is detachably connected to the receiving cavity 11, and connecting part 2 82 is detachably connected to the arc-shaped mounting groove 14. Specifically, connecting part 1 81 of the connecting plate 8 is fixed to the receiving cavity 11 by bolts or clips, and connecting part 2 82 engages with the arc-shaped mounting groove 14 by embedding or clipping. The detachable connection between connecting part 1 81 and the receiving cavity 11 facilitates quick replacement or maintenance of the conveying components, while the detachable connection between connecting part 2 82 and the arc-shaped mounting groove 14 ensures installation accuracy and sealing.

[0082] The delivery outlet 83 can be designed as a flat or other irregular shape. In this embodiment, the delivery outlet 83 is a flat opening. The flat opening reduces sudden changes in fluid flow rate and reduces the impact on the connection structure, allowing the fluid to be delivered to the receiving cavity 11 more evenly.

[0083] This application further proposes that the delivery pipe 6, delivery joint 7 and connecting plate 8 are manufactured as a single unit, realizing the modular design of the jet device, which facilitates assembly and maintenance. In addition, the integrally manufactured delivery pipe 6, delivery joint 7 and connecting plate 8 eliminate assembly gaps, improve sealing performance, reduce leakage risk, and improve structural strength and sealing performance.

[0084] This application also provides a decontamination system, including a jetting device and a pump set, the pump set being used to pump fluid into the receiving cavity 11 of the jetting device.

[0085] The pump unit is hydraulically driven and connected to the receiving cavity 11 of the jetting device via a sealed pipeline. A pressure regulating valve is installed at the output end of the pump unit. The pump unit includes a gear pump or a plunger pump. A check valve is installed between the pump unit and the jetting device to prevent backflow of fluid. The pump unit is equipped with a pressure sensor to monitor the internal pressure of the receiving cavity 11 in real time and feed the data back to the control system. The control system dynamically adjusts the output power of the pump unit according to a preset pressure threshold.

[0086] The pump unit injects pressurized fluid into the receiving cavity 11 through the delivery pipeline. The fluid accelerates at the jet orifice 13 to form a planar jet layer. When the pump unit outputs at the pressure threshold, the fluid forms a continuous and stable laminar flow at the outlet of the jet orifice 13. When the pressure sensor detects that the pressure in the receiving cavity 11 is lower than the preset pressure threshold, the control system automatically increases the pump unit speed to maintain the flow velocity at the outlet of the jet orifice 13, ensuring that the fluid layer formed at the slit nozzle 4 completely covers the surface to be cleaned. The coordinated operation of the pump unit and the jet device reduces the amount of cleaning fluid consumed per unit area compared to traditional rotary nozzle systems, while improving the uniformity of fluid coverage in the edge areas of the curved surface.

[0087] Through the above technical solution, this application effectively solves the technical defect of uneven fluid distribution in curved surface decontamination. The planar jet achieves full fluid coverage of the surface to be decontaminated by precisely matching the shape of the slit nozzle 4 to the curvature of the curved surface. The pump pressure regulation function ensures that the jet velocity adapts to different levels of contamination, maintaining effective impact force while avoiding excessive liquid consumption. The closed-loop control system ensures the stability of fluid supply, keeping the jet shape uniform during the decontamination process, significantly improving stain removal efficiency, especially in high-curvature areas.

[0088] This application also provides an electronic device component, including an electronic device and a jetting device or a decontamination system. The electronic device has a surface to be decontaminated, the jetting device is located at the upper or lower edge of the electronic device, and the slit nozzle 4 is parallel or nearly parallel to the surface to be decontaminated. The electronic device is a radar or camera, etc.

[0089] When the jet device is installed on the edge of the electronic device, the extension direction of the slit nozzle 4 is parallel or nearly parallel to the surface to be cleaned, so that the fluid covers the surface to be cleaned in a planar form; the curvature of the side of the jet body 1 facing the surface to be cleaned is the same as or similar to the curvature of the surface to be cleaned, ensuring that the fluid flows in line with the curved surface after being ejected. The pump group continuously pumps fluid into the receiving cavity 11 through the delivery pipe 6. After the fluid enters the fluid ejection cavity 3 through the jet hole 13, it is evenly ejected from the slit nozzle 4 to form a cleaning layer covering the curved surface.

[0090] Taking vehicle-mounted radar as an example, the jet device is installed on the upper or lower edge of the radar dome. The slit nozzle 4 extends along the arc-shaped surface of the radar dome, and the center line of the slit nozzle 4 is parallel to the tangent direction of the radar dome surface. The fluid diffuses along the surface of the dome in a laminar flow form, covering the high curvature area.

[0091] Specifically, the jet device is installed along the lower edge of the radar dome. The plane of the slit nozzle 4 of the jet device is parallel to the tangent direction of the outer surface of the radar dome. The extension direction of the slit nozzle 4 is consistent with the arc direction of the lower edge of the radar dome. The pump group pumps the decontamination liquid into the receiving cavity 11 of the jet body 1. The fluid enters the fluid ejection cavity 3 through the jet hole 13. The diameter of the jet hole 13 gradually increases along the flow direction.

[0092] When the pump unit starts, the cleaning liquid is evenly covered on the surface of the protective cover from the flat fluid ejection chamber 3. The resulting planar jet spreads along the tangent of the curved surface, and multiple jet holes 13 are arranged in an alternating manner to generate laminar flow coverage.

[0093] Through the above technical solution, this application effectively solves the problem of uneven distribution of cleaning liquid on curved electronic device surfaces. The planar jet unfolds along the tangent direction of the curved surface to form a continuous liquid film, avoiding the local high-pressure impact and droplet splashing caused by traditional rotating nozzles. The flat slit nozzle 4 remains parallel to the curved surface, allowing the cleaning liquid to form a uniformly adhered liquid layer on the curved surface, which then flows naturally down the curved surface under gravity, carrying away contaminants. This arrangement is particularly suitable for high-curvature surfaces such as vehicle camera protective covers and radar domes, achieving non-contact cleaning while avoiding mirror scratches that may be caused by manual wiping.

[0094] This application also provides a vehicle, including a vehicle body and a jetting device or decontamination system installed on the vehicle body. The vehicle body is equipped with electronic monitoring equipment, and the jetting device is disposed on the vehicle body and located at the upper or lower edge of the electronic monitoring equipment; or, the vehicle includes a vehicle body and an electronic equipment assembly, the electronic equipment assembly including electronic monitoring equipment and a jetting device, the jetting device being located at the upper or lower edge of the electronic monitoring equipment, and the slit nozzle 4 being parallel or nearly parallel to the surface of the electronic monitoring equipment to be decontaminated.

[0095] Among them, electronic monitoring equipment can be lidar, cameras or sensors, etc. The following uses lidar as an example.

[0096] A lidar is installed on the roof of the vehicle. The outer surface of the lidar has a convex arc structure. The flat opening of the slit nozzle 4 and the curvature of the jet body 1 are adapted to the curvature of the lidar surface. The jet device is installed on the upper or lower edge of the lidar. For example, when the jet device is installed on the lower edge of the lidar, the fluid covers the entire curved surface from bottom to top, using gravity to enhance the stain washing effect and ensure the coverage and cleaning strength of the surface fluid.

[0097] In some embodiments, the delivery assembly can be fixedly installed on the vehicle body as a load-bearing body. The jet body 1 and the delivery assembly are connected to the receiving cavity 11 through a first connection part 81, and the second connection part 82 is connected to the arc-shaped mounting groove 14, so as to realize the detachable installation of the jet body 1 and the vehicle body.

[0098] The fluid is delivered via a pipe and a hose to a reservoir located at the bottom of the vehicle. The pump unit is integrated into the vehicle's electrical system. After the decontamination command is triggered by the onboard controller, the pump unit pressurizes and delivers the decontamination fluid to the receiving cavity 11. When the fluid is pumped into the receiving cavity 11 through the delivery pipe 6, the jet orifice 13 guides the fluid to the fluid ejection cavity 3. The arc-shaped structure design of the slit nozzle 4 and the jet body 1 allows the fluid to cover the radar surface in a planar manner. Because the jet device is located at the edge of the lidar and the slit nozzle 4 is parallel to the surface, the fluid can diffuse evenly along the tangent direction of the curved surface, avoiding local decontamination blind spots caused by jet angle deviation.

[0099] Through the above technical solution, the spatial coordination between the jet device and the radar curved surface structure enables the ejected fluid to form a continuous liquid film layer. The liquid film spreads evenly along the curved surface to achieve corner-free decontamination. The flat fluid ejection cavity 3 structure ensures that the decontamination liquid covers the high curvature area in a laminar flow state. The integrated installation method of the jet device and the radar effectively avoids airflow interference during vehicle movement, and significantly improves the decontamination reliability of complex curved surfaces in dynamic environments.
