[0028] The following beneficial effects will be obtained by implementing the embodiments of this application:

[0029] According to the liquid source sealed connection structure in the above embodiments, the liquid pump can be housed in the first receiving cavity. When the liquid pump is running, the liquid in the second receiving cavity of the second housing can enter the liquid pump through the second channel and the first channel.

[0041] 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

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0043] With the development of modern intelligent and digital technologies, modern vehicle technology has also made great strides. For example, a certain number of cameras or lidar and other information collection components are installed on the vehicle body, enabling the vehicle to identify the surrounding road conditions in order to achieve the purposes of obstacle avoidance, driving guidance and improving driving safety.

[0044] The aforementioned cameras or lidar are susceptible to weather conditions. For example, when a car is driving in fog, dust, rain, or snow, the surface of the camera or lidar will be covered with dirt. In order to maintain the basic performance of the camera or lidar, it is necessary to perform a cleaning operation on the camera or lidar to prevent the dirt attached to the camera or lidar from affecting the clarity of the monitoring image.

[0045] In related technologies, a gas-liquid two-phase decontamination device that combines gas and liquid decontamination can achieve efficient decontamination operations. This decontamination device can clean various types of dirt by spraying gas and / or liquid into the dirt.

[0046] The liquid source assembly is a component of a gas-liquid two-phase decontamination device. The main purpose of the liquid source assembly is to form a liquid flow. The liquid source assembly usually includes a liquid pump, a liquid supply source (water tank, water jug, etc.), and a pipeline connecting the liquid pump and the liquid supply source.

[0047] To form a liquid flow, the liquid source assembly in related technologies needs to draw liquid from the supply source using a liquid pump and then eject it using the power of the liquid pump or other power components. The airtightness between the liquid pump and the supply source has a significant impact on the formation of the liquid flow. When air leakage occurs, it will cause adverse consequences such as the liquid pump running dry, cavitation, and affecting the flow rate and velocity of the liquid, thereby affecting the overall decontamination performance of the gas-liquid two-phase decontamination device. Therefore, a sealed connection needs to be formed between the liquid pump and the supply source.

[0048] Therefore, one end of the pipe can be sealed to the inlet of the liquid pump, and the other end can be sealed to the outlet of the liquid pump. This connection method creates two connection nodes between the liquid pump and the liquid supply source. Ensuring the seal at both connection nodes is crucial for a reliable seal between the pump and the supply source. This places high demands on the sealing connection and makes it difficult to achieve a reliable seal. On the other hand, taking the connection between the pipe and the liquid pump inlet as an example, a pipe fitting or sealing ring can be used to create a seal. However, this method is susceptible to vibration, temperature changes, and other factors, which can easily cause the connection to loosen or the connecting components to age, leading to seal failure and affecting the reliability of the seal.

[0049] Therefore, due to its structural design, the liquid source assembly in related technologies suffers from insufficient sealing reliability because it is difficult to achieve a reliable seal between the liquid pump and the liquid supply source. Furthermore, since the pipeline needs to connect to both the liquid pump and the liquid supply source simultaneously, forming two connection nodes, the required connecting components increase, resulting in a cumbersome connection process and high cost for the liquid source assembly as a whole.

[0050] Based on the above-mentioned situation and problems, this application provides a liquid source sealing connection structure, which can realize the sealed assembly of the liquid source assembly and improve the sealing reliability between the liquid pump and the liquid supply source.

[0051] To achieve the above objectives, firstly, the liquid source sealing connection structure in this application embodiment may include two housings and eliminates the design of pipes. The two housings adopt an internal hollow design, and each housing has a cavity. One housing can store liquid and act as a liquid source, while the other housing can enclose the liquid pump or form an integrated design with the liquid pump. Each housing has a connecting end, and the two connecting ends can be inserted to achieve communication. Secondly, the liquid source sealing connection structure in this application embodiment is also equipped with an elastic sealing element, which can be interference-fitted between the two connecting ends to form a sealed connection between the two connecting ends.

[0052] It is understandable that, for the above-mentioned liquid source sealed connection structure, the liquid pump can be placed in the first receiving cavity of the first housing to form a liquid source assembly.

[0053] Understandably, by eliminating the need for piping, the fluid power supply assembly only requires connecting two ends, reducing the use of connecting components and thus lowering costs and simplifying the connection process. Furthermore, the inclusion of an elastic seal allows for a sealed connection between the two ends based on the seal's elastic deformation. This elastic seal can be designed with excellent vibration resistance and temperature resistance, improving the sealing reliability between the two housings and consequently enhancing the overall sealing reliability of the fluid power supply assembly.

[0054] Based on the above-mentioned liquid source sealed connection structure, this application embodiment also provides a gas-liquid two-phase decontamination device, which includes the above-mentioned liquid source sealed connection structure. The liquid source sealed connection structure is part of the liquid source assembly. The gas-liquid two-phase decontamination device may also include a gas source assembly. The liquid source assembly may be connected to one side of the gas source assembly. The main purpose of the gas source assembly is to form an airflow.

[0055] It is understandable that, due to the configuration of the above-mentioned liquid source sealing connection structure, the gas-liquid two-phase decontamination device in this application embodiment has the advantages of simple connection process, low cost and reliable sealing, and the overall performance of the gas-liquid two-phase decontamination device is improved.

[0056] Figure 1 A schematic diagram of a gas-liquid two-phase decontamination device according to an embodiment of this application is shown; Figure 2 It shows Figure 1 A cross-sectional view along the AA direction; Figure 3 It shows Figure 2 A magnified view of part B in the diagram.

[0057] In the embodiments of this application, please refer to Figure 2 The gas-liquid two-phase decontamination device may include a gas source assembly 10 and a liquid source assembly 20, wherein the liquid source assembly 20 is connected to the upper side of the gas source assembly 10.

[0058] The upper side here can be based on Figure 2 To understand the directional markers in the text, Figure 2 In the example shown, the liquid source assembly 20 is located on the upper side, and the gas source assembly 10 is located on the lower side.

[0059] The air source assembly 10 is a component capable of forming airflow. The specific structure and composition of the air source assembly 10 are not limited in the embodiments of this application. For example, the air source assembly 10 may include an air source assembly housing 11, an air pump disposed in the air source assembly housing 11, and an air passage pipe disposed in the air source assembly housing 11. After the air pump is running, it can form a negative pressure in the air source assembly housing 11. Then, outside air can enter the air source assembly housing 11, and then the airflow is ejected out of the air source assembly housing 11 with the help of the power of the air pump and the air passage pipe.

[0060] The aforementioned air source assembly housing 11 can be constructed as a whole into a cuboid or columnar structure, with a sealed cavity inside, where the air pump, air pipelines, etc., can be housed. The air source assembly 10 can also be constructed into other structures, which will not be described in detail in the embodiments described herein.

[0061] In the embodiments of this application, please refer to Figures 1 to 3 The liquid source assembly 20 may include a liquid source sealing connection structure and a liquid pump. The liquid source sealing connection structure includes a first housing 100, a second housing 200, and an elastic seal 400.

[0062] The first housing 100 and the second housing 200 correspond to the two housings mentioned above. The first housing 100 has a first receiving cavity 101, which is a cavity in the first housing 100. The second housing 200 has a second receiving cavity 201, which is a cavity in the second housing 200.

[0063] The first housing 100 and the second housing 200 are the external structures of the liquid source assembly 20. From the outside, the liquid source assembly 20 includes the first housing 100 and the second housing 200.

[0064] The first receiving cavity 101 of the first housing 100 can accommodate structures such as a liquid pump. At least a portion of the shell wall of the first housing 100 is formed with a first connecting end 110, which has a first channel 111 communicating with the first receiving cavity 101.

[0065] It should be noted that the shell wall of the first housing 100 is a solid portion forming the first housing 100, and this shell wall can enclose a first receiving cavity 101. At least a portion of the shell wall of the first housing 100 can extend outward to form a first connecting end 110.

[0066] The specific structure of the first housing 100 is not limited. In some embodiments, the first housing 100 can be a cuboid structure, while in other embodiments, the first housing 100 can be a columnar structure.

[0067] The second housing 200 has a second receiving cavity 201 for storing liquid, and at least a portion of the shell wall of the second housing 200 has a second connecting end 210, which has a second channel 211 communicating with the second receiving cavity 201.

[0068] It should be noted that the shell wall of the second housing 200 is a solid portion forming the second housing 200, and this shell wall can enclose the second receiving cavity 201. At least a portion of the shell wall of the second housing 200 can extend outward to form a second connecting end 210.

[0069] The specific structure of the second housing 200 is not limited. In some embodiments, the second housing 200 can be a cuboid structure, while in other embodiments, the second housing 200 can be a columnar structure.

[0070] The second connection end 210 is used to form a plug-in engagement with the first connection end 110, that is, the first connection end 110 can be plugged into the second connection end 210, or the second connection end 210 can be plugged into the first connection end 110.

[0071] After the first connecting end 110 and the second connecting end 210 are plugged in, the first channel 111 will be connected to the second channel 211, thereby realizing the connection between the first housing 100 and the second housing 200.

[0072] The liquid pump is located in the first receiving cavity 101 and is connected to the first channel 111. Thus, the second receiving cavity 201, the second channel 211, the first channel 111 and the liquid pump can be connected, so that the liquid in the second receiving cavity 201 can enter the liquid pump under the action of the liquid pump.

[0073] The elastic seal 400 is constrained between the first connecting end 110 and the second connecting end 210, and after the first connecting end 110 and the second connecting end 210 are inserted and engaged, it undergoes elastic deformation in the radial and / or axial directions, thereby forming a radial and / or axial interference seal at the connection between the first channel 111 and the second channel 211. This can form a seal between the first connecting end 110 and the second connecting end 210, preventing liquid from leaking between the first connecting end 110 and the second connecting end 210, and also preventing air from entering the first receiving cavity 101 and / or the liquid pump, thus protecting the liquid pump.

[0074] It is understood that, in order to achieve an interference seal, the elastic seal 400 can be compressed between the first connecting end 110 and the second connecting end 210. This purpose can be achieved by designing the relevant dimensions and fits of the elastic seal 400, the first connecting end 110, and the second connecting end 210. The dimensional relationships and fits of the elastic seal 400, the first connecting end 110, and the second connecting end 210 can be understood in conjunction with the following embodiments.

[0075] In this embodiment, the material of the elastic seal 400 can be selected from silicone, rubber or other materials with elastic properties.

[0076] In this embodiment of the application, when the liquid pump is running, the liquid in the second receiving cavity 201 of the second housing 200 can enter the liquid pump through the second channel 211 and the first channel 111. As the liquid pump continues to run, a liquid flow can be formed, so that the liquid source assembly 20 can realize the basic function of forming a liquid flow based on the liquid source sealed connection structure. In this embodiment, a liquid pump is disposed in the first receiving cavity 101 of the first housing 100, and a first connecting end 110 is formed on the first housing 100. At the same time, a second connecting end 210 is formed on the second housing 200. The second connecting end 210 can be plugged into the first connecting end 110 to realize the communication between the second receiving cavity 201, the second channel 211, the first channel 111 and the liquid pump. This creates a structural basis for the flow of liquid from the second receiving cavity 201 to the liquid pump. The external structure of the liquid source assembly 20 is formed by the combination of the first housing 100 and the second housing 200. The connection node between the first housing 100 and the second housing 200 is only manifested as the connection between the first connecting end 110 and the second connecting end 210. This reduces the use of related connecting devices, thereby reducing costs and simplifying the connection process. On the other hand, since an elastic seal 400 is provided between the first connecting end 110 and the second connecting end 210, and the elastic seal 400 is interference-sealed at the connection between the first channel 111 and the second channel 211, it can prevent liquid from leaking between the first connecting end 110 and the second connecting end 210, and can also prevent air from entering the liquid pump. The elastic seal 400 can be designed to have excellent vibration resistance and temperature resistance, which can improve the sealing reliability between the two housings, thereby improving the sealing reliability of the liquid source assembly 20.

[0077] In some embodiments, please refer to Figures 1 to 3 One of the first connecting end 110 and the second connecting end 210 has a plug-in interface 212, and the other is plugged into the plug-in interface 212.

[0078] The connector 212 can be configured in an expanded form, so that the first connection end 110 or the second connection end 210 can be inserted into the connector 212 more conveniently.

[0079] To simplify the description and facilitate understanding, the following embodiments are illustrated by taking the example of the plug interface 212 being formed on the second connection end 210. It can be understood that the plug interface 212 is connected to the second channel 211.

[0080] In some embodiments, please refer to Figures 1 to 3 The second connecting end 210 includes a plug interface 212, and the first connecting end 110 is inserted into the plug interface 212. The outer diameter of the first connecting end 110 is smaller than the inner diameter of the plug interface 212, and the elastic seal 400 is disposed in the gap between the first connecting end 110 and the plug interface 212.

[0081] Specifically, the insertion interface 212 can be formed by expanding outward from the end of the second channel 211. After the first connecting end 110 is inserted into the insertion interface 212, since the outer diameter of the first connecting end 110 is smaller than the inner diameter of the insertion interface 212, the elastic seal 400 can be restricted between the first connecting end 110 and the insertion interface 212.

[0082] It is understood that the elastic seal 400 can be fitted around the outer periphery of the first connecting end 110, thereby forming a seal between the first connecting end 110 and the insertion interface 212.

[0083] In some embodiments, please refer to Figures 1 to 3 The first connecting end 110 includes a first connecting part 112 and a second connecting part 113 protruding on the first connecting part 112, and the second connecting part 113 is inserted into the plug interface 212.

[0084] The arrangement of the first connecting part 112 and the second connecting part 113 can change the connection orientation between the first connecting end 110 and the second connecting end 210, which facilitates the overall layout of the liquid source assembly 20.

[0085] Specifically, the first connecting portion 112 can be a portion extending in a first direction on the first housing 100, and the second connecting portion 113 can be a portion extending in a second direction on the first housing 100. The first direction and the second direction are different, thereby changing the portion and insertion position of the first connecting end 110 that needs to be inserted with the second connecting end 210, which facilitates the overall layout of the liquid source assembly 20. For example, as can be seen from the following embodiments, the first connecting end 110 and the second connecting end 210 can be stacked, and the arrangement of the second connecting portion 113 can fit this stacked arrangement relationship, which can reduce the overall height of the liquid source assembly 20.

[0086] In some embodiments, please refer to Figures 1 to 3The elastic seal 400 includes a first sealing part 410 and a second sealing part 420. The first sealing part 410 is located between the outer wall surface of the second connecting part 113 and the inner wall surface of the insertion interface 212, and the second sealing part 420 is located between the first connecting part 112 and the outer wall surface of the second connecting end 210.

[0087] In specific design, the first sealing part 410 and the second sealing part 420 can be perpendicular to each other. The first sealing part 410 can form a seal between the outer wall surface of the second connecting part 113 and the inner wall surface of the insertion interface 212, and the second sealing part 420 can form a seal between the first connecting part 112 and the outer wall surface of the second connecting end 210. Multiple seals can be achieved through the same elastic sealing element 400, thereby improving the sealing effect and sealing reliability.

[0088] In some embodiments, the elastic seal 400 has a hollow channel 401, and the second connecting portion 113 is inserted into the hollow channel 401. The outer diameter of the first sealing portion 410 is smaller than the inner diameter of the insertion interface 212, and the inner diameter of the hollow channel 401 is smaller than the outer diameter of the second connecting portion 113.

[0089] During the assembly of the liquid pump assembly, the elastic seal 400 can be inserted into the connector 212 first. Since the outer diameter of the first sealing part 410 is smaller than the inner diameter of the connector 212, the elastic seal 400 can be confined in the connector 212. Since the inner diameter of the hollow channel 401 is smaller than the outer diameter of the second connecting part 113, when the second connecting part 113 is inserted into the hollow channel 401, the second connecting part 113 can compress the first sealing part 410, thereby making the first sealing part 410 interference fit between the second connecting part 113 and the connector 212.

[0090] The second sealing portion 420 can also be pressed between the first connecting portion 112 and the second connecting end 210, for example, please refer to Figures 1 to 3 The first housing 100 can be locked onto the air source assembly 10 by fasteners such as screws. By properly configuring the locking force, the first connecting part 112 can be driven to squeeze the second sealing part 420, thereby achieving the sealing effect of the second sealing part 420.

[0091] Furthermore, since the first connecting part 112 can exert a compressive force on the second sealing part 420, it can prevent the elastic seal 400 from detaching from the insertion interface 212, thereby ensuring the long-term durability of the elastic seal 400.

[0092] In some embodiments, please refer to Figures 1 to 3 The outer wall surface of the first sealing part 410 is formed with at least one ring of first flange 411 and / or the inner wall surface of the insertion interface 212 is formed with at least one ring of first flange 411.

[0093] Because of the first flange 411, the first sealing part 410 and the insertion interface 212 can form a tighter fit, which can improve the sealing performance and sealing reliability.

[0094] In some embodiments, please refer to Figures 1 to 3 The inner wall surface of the first sealing part 410 is formed with at least one ring of second flange 412 and / or the outer wall surface of the second connecting part 113 is formed with at least one ring of second flange 412.

[0095] Because of the second flange 412, the second connecting part 113 and the first sealing part 410 can form a tighter fit, which can improve the sealing performance and improve the sealing reliability.

[0096] In some specific embodiments, when the first flange 411 and the second flange 412 are provided simultaneously, the first flange 411 and the second flange 412 are spaced apart along the axial direction of the second connecting portion 113. As a result, multiple sealing mating surfaces can be formed along the axial direction of the second connecting portion 113, thereby improving the sealing effect and the connection reliability between the second connecting portion 113, the insertion interface 212 and the elastic seal 400.

[0097] The number of the first flange 411 and the second flange 412 in the above embodiments can be set according to actual needs. For example, when the insertion interface 212 has a deeper depth, more first flanges 411 can be set. Similarly, when the length of the second connecting part 113 is longer, more second flanges 412 can be set.

[0098] Furthermore, the specific shapes of the first flange 411 and the second flange 412 are not limited, and their cross-sections can be constructed into rectangular, triangular, semi-circular, or other structures.

[0099] In some embodiments, the end of the second connecting part 113 may be provided with a chamfer or a tapered guide head, and the outer edge of the hollow channel 401 is provided as a flared opening, so that the second connecting part 113 can be smoothly inserted into the elastic seal 400.

[0100] In some embodiments, a hook or similar structure may be provided on the outer wall surface of the first sealing part 410 or the inner wall surface of the insertion interface 212 to prevent the elastic seal 400 from detaching from the insertion interface 212.

[0101] In some embodiments, hooks or other structures may be provided on the outer wall of the second connecting part 113 or the inner wall of the hollow channel 401 to prevent the second connecting part 113 from detaching from the hollow channel 401.

[0102] In some embodiments, the length of the second connecting portion 113 located in the hollow channel 401 is less than the length of the hollow channel 401.

[0103] Therefore, when the second connecting part 113 is fully inserted into the hollow channel 401, the end of the second connecting part 113 will not contact the inner wall of the second housing 200. Sufficient tolerance can be formed between the second connecting part 113 and the second housing 200 to avoid assembly stress between the two. This ensures that all seals are provided by the deformation of the elastic seal 400, which can make the seal more reliable and also ensure the long-term use of the elastic seal 400.

[0104] In some embodiments, please refer to Figures 1 to 3 The second connecting end 210 is also provided with a first limiting step 213 on the outer periphery of the insertion interface 212, and the second sealing part 420 is restricted to one side of the first limiting step 213.

[0105] The first limiting step 213 provides a guiding function for the assembly of the elastic seal 400. During assembly, the outer wall of the second sealing part 420 abuts against the first limiting step 213, allowing the elastic seal 400 to be smoothly inserted into the insertion interface 212. Furthermore, after the installation of the elastic seal 400 is completed, the first limiting step 213 restricts movement of the elastic seal 400, thereby improving the stability of the elastic seal 400 in the insertion interface 212.

[0106] In some embodiments, please refer to Figures 1 to 3 The second connecting end 210 is also provided with a second limiting step 214 on the outer periphery of the insertion interface 212, and the first connecting part 112 is restricted to one side of the second limiting step 214.

[0107] The first limiting step 213 can provide guidance and positioning for the assembly of the first connecting end 110, so that the first connecting end 110 can be assembled into the elastic seal 400 along the second limiting step 214.

[0108] In some embodiments, please refer to Figures 1 to 3 The first connecting end 110 and the second connecting end 210 are stacked.

[0109] Can be combined Figure 2 Understanding the above stacking relationships, in Figure 2In the example shown, the liquid source assembly 20 is positioned above the gas source assembly 10. For the liquid source assembly 20, the first housing 100 and the second housing 200 are spaced apart in the left-right direction, with the first connecting end 110 positioned above the second connecting end 210. This stacked arrangement allows the first housing 100 and the second housing 200 to overlap to a certain extent in the height direction (defined by the vertical direction), thereby facilitating control over the overall shape of the liquid source assembly 20 and reducing its overall height.

[0110] In some embodiments, the first housing 100 includes a first body 120 and a first connecting end 110 extending outward from the outer edge of the first body 120, and the second housing 200 includes a second body 220 and a second connecting end 210 extending outward from the outer edge of the second housing 200, with the first connecting end 110 located above the second connecting end 210.

[0111] In some embodiments, the second connection end 210 is close to the bottom of the second body 220, so that the second channel 211 in the second connection end 210 can be as low as possible below the liquid level in the second receiving cavity 201, thereby making full use of the liquid in the second receiving cavity 201.

[0112] In some embodiments, the liquid source assembly 20 further includes a liquid passage 500, and the first housing 100 is also provided with a liquid outlet 102 communicating with the first receiving cavity 101. The liquid pump includes a liquid pump inlet and a liquid pump outlet, and the liquid passage 500 is connected between the first connecting end 110 and the liquid pump inlet and between the liquid outlet 102 and the liquid pump outlet.

[0113] The aforementioned outlet 102 is a port of the liquid source assembly 20 for ejecting liquid flow, and the liquid flow formed by the liquid source assembly 20 can be ejected from the outlet 102.

[0114] The liquid conduit 500 can be a rigid conduit and integrated into the first housing 100. Of course, the liquid conduit can also be a flexible conduit.

[0115] In some embodiments, the liquid pump can be integrated into the first housing 100, thereby simplifying the structural composition of the first housing 100 and reducing the manufacturing cost of the first housing 100.

[0116] In the embodiment where both the liquid pipeline 500 and the liquid pump are integrated into the first housing 100, the overall assembly process of the liquid source assembly 20 can be briefly described as follows: First, the second housing 200 is fixedly connected to the gas source assembly 10, and then the second housing 200 is fixedly connected to the gas source assembly 10. During the assembly of the second housing 200, it is necessary to ensure the precise docking of the first connecting end 110 and the second connecting end 210.

[0117] The first limiting step 213 and the second limiting step 214 in the above embodiments can provide assistance for precise docking.
