In this liquid pump assembly, the liquid pump and pipeline can be housed in the housing cavity of the liquid pump assembly housing. Specifically, the liquid pump is housed in the liquid pump cavity, and the pipeline is housed in the peripheral cavity. Since the peripheral cavity is located on at least one side of the liquid pump cavity, the pipeline can make full use of the peripheral space of the liquid pump for arrangement, which can reduce the overall volume of the housing cavity and help control the space ratio of the liquid pump assembly housing. This allows the liquid pump assembly housing, liquid pump, and pipeline to form a highly integrated liquid pump assembly. When installing the liquid pump assembly, only the liquid pump assembly housing needs to be installed in the designated position, thereby achieving the purpose of saving vehicle interior space, reducing installation difficulty, and improving installation efficiency.

[0043] 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

[0044] 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.

[0045] 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.

[0046] 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.

[0047] In related technologies, a decontamination device that combines gas and liquid decontamination can achieve highly efficient decontamination operations. This type of device can clean various types of dirt by spraying airflow and / or liquid flow onto the dirt. To generate liquid flow, the decontamination device needs to be equipped with a liquid pump and its pipelines and wiring; to generate airflow, the decontamination device needs to be equipped with an air pump and its pipelines and wiring.

[0048] In related technologies, hydraulic pumps and their pipelines and wiring are usually arranged loosely in vehicles. This arrangement not only occupies the vehicle's interior space, but also increases the difficulty of installing hydraulic pumps and reduces their installation efficiency.

[0049] Based on the above-mentioned situation and problems, this application provides a liquid pump assembly. The liquid pump assembly adopts an integrated design, which can achieve a high degree of integration of the liquid pump and its pipeline (which may also include wiring). It can achieve synchronous installation of the liquid pump and its pipeline, and has the advantages of saving vehicle interior space, low installation difficulty and high installation efficiency.

[0050] Therefore, the hydraulic pump assembly in this embodiment is equipped with a hydraulic pump assembly housing and the internal space of the hydraulic pump assembly housing is reasonably planned so that the hydraulic pump and its pipeline can be housed in the hydraulic pump assembly housing. Furthermore, the hydraulic pump and its pipeline are arranged reasonably, which can reduce the size of the hydraulic pump assembly housing. When installing the hydraulic pump assembly, it is only necessary to install the hydraulic pump assembly housing in the designated position, thereby achieving the purpose of saving vehicle interior space, reducing installation difficulty, and improving installation efficiency.

[0051] Based on the above-mentioned liquid pump assembly, this application embodiment also provides a decontamination device, which may include the above-mentioned liquid pump assembly. Based on the integrated design of the liquid pump assembly, the decontamination device can also be more compact in structure, so that when installing the decontamination device, it can save vehicle interior space, reduce installation difficulty and improve installation efficiency.

[0052] Figure 1 A schematic diagram of a liquid pump assembly according to an embodiment of this application is shown; Figure 2 A schematic diagram of the internal structure of a liquid pump assembly provided according to an embodiment of this application is shown; Figure 3 This diagram shows the internal structure of a liquid pump assembly removing the pipeline 300 and line 400 according to an embodiment of this application; Figure 4 A schematic diagram of the internal structure of a liquid pump assembly, including the removal pipeline 300, the line 400, and the liquid pump 200, is shown according to an embodiment of this application.

[0053] In the embodiments of this application, please refer to Figures 1 to 4 The pump assembly includes a pump assembly housing 100, a pump 200, and piping 300. The pump assembly may also include wiring 400.

[0054] The pump assembly housing 100 is a protective housing for the pump assembly. Other components of the pump assembly can be housed in the pump assembly housing 100. Therefore, the pump assembly housing 100 has a receiving cavity 101.

[0055] To reduce weight and facilitate installation, the housing 100 of the liquid pump assembly can be made of materials such as hard plastic. Of course, in other embodiments, the housing 100 of the liquid pump assembly can also be made of aluminum alloy or other metal materials.

[0056] To facilitate the installation of other parts of the pump assembly into the pump assembly housing 100, the pump assembly housing 100 in this embodiment may include a base 110 and a cover 120. The cover 120 may be fitted onto the base 110 to form a receiving cavity 101.

[0057] In order to fit the installation of the liquid pump assembly, make full use of the installation space, and facilitate the assembly of the liquid pump assembly housing 100 itself, the embodiments of this application have made relevant designs on the base 110 and the top cover. These relevant designs are mainly reflected in optimizing the structural layout, enhancing the structural strength, and avoiding design, etc. These designs can be understood with reference to the following embodiments.

[0058] Furthermore, after the other parts of the pump assembly are installed into the pump assembly housing 100, a sealed connection can be achieved between the base 110 and the cover 120. Specifically, the connection can be made by ultrasonic welding, which gives the pump assembly good waterproof performance and makes it suitable for special environments such as underwater.

[0059] The receiving cavity 101 in this embodiment may include a liquid pump cavity 101a and a peripheral cavity 101b located on at least one side of the liquid pump cavity 101a. The liquid pump cavity 101a can be adapted to the installation of the liquid pump 200, and the peripheral cavity 101b can be adapted to the pipeline 300 and the arrangement of the line 400.

[0060] It is understood that by setting the peripheral cavity 101b on at least one side of the liquid pump cavity 101a, the peripheral cavity 101b can utilize the peripheral space of the liquid pump cavity 101a, thereby reducing the overall volume of the receiving cavity 101 and helping to control the size of the liquid pump assembly housing 100.

[0061] The pump assembly housing 100 also has an inlet 102 and an outlet 103 communicating with the receiving cavity 101. In some embodiments, the pump assembly housing 100 also has a line outlet 104 communicating with the receiving cavity 101.

[0062] Under the action of the liquid pump 200, the liquid in the reservoir can enter the liquid pump 200 through the liquid inlet 102, and then be transported to the designated location through the liquid outlet 103.

[0063] As can be seen from the following embodiments in this application, the aforementioned inlet 102, outlet 103, and line outlet 104 can be formed by openings at appropriate locations on the pump assembly housing 100, or by other structures connected to the pump assembly housing 100. For example, a first pipe connector 500 can be connected to the inlet 102, and the outer end of the first pipe connector 500 can form the inlet 102. Similarly, a second pipe connector 600 can be connected to the outlet 103, and the outer end of the second pipe connector 600 can form the outlet 103. For the sake of consistency, the inlet 102 and outlet 103 in the embodiments of this application are described as being formed on the pump assembly housing 100.

[0064] Line outlet 104 is a terminal in the liquid pump assembly, through which the liquid pump 200 can be connected to the power supply equipment.

[0065] The liquid pump 200 is suitable for installation in the liquid pump chamber 101a. Specifically, the liquid pump 200 can be installed in the liquid pump chamber 101a by means of screw connection, snap-fit, etc. The liquid pump 200 is the power element in the liquid pump assembly, and its function is to pump liquid to a designated location. It should be noted that the embodiments of this application do not limit the specific structure and type of the liquid pump 200. For example, in... Figure 2 In the example shown, the liquid pump 200 is generally rectangular in shape, and the liquid pump chamber 101a is adapted to the external structure of the liquid pump 200.

[0066] The liquid pump 200 has a liquid pump inlet and a liquid pump outlet. It can be understood that the liquid pump inlet can be connected to the liquid inlet 102 through the pipe 300, and the liquid pump outlet can also be connected to the liquid outlet 103 through the pipe 300.

[0067] In this embodiment, the pipe 300 is housed in the peripheral cavity 101b, and the pipe 300 is connected between the liquid inlet 102 and the liquid pump inlet, and between the liquid outlet 103 and the liquid pump outlet.

[0068] Specifically, the pipeline 300 may include an inlet pipeline 310 and an outlet pipeline 320, wherein the inlet pipeline 310 is used to connect the inlet port 102 and the pump inlet, and the outlet pipeline 320 is used to connect the pump outlet and the outlet port 103.

[0069] To form an effective sealed connection, sealing rings or other structures can be installed at both ends of the pipe 300. Alternatively, as described above, the pipe 300 can also be sealed to the first pipe joint 500 or the second pipe joint 600.

[0070] The aforementioned conduit 300 can be made of metal, rigid plastic, or polymer material. Of course, to facilitate the layout of the conduit 300 in the receiving cavity 101, the conduit 300 can also be made of a flexible hose.

[0071] In this embodiment, the line 400 can also be housed in the peripheral cavity 101b. One end of the line 400 is connected to the liquid pump 200, and the other end of the line 400 is led out from the line outlet 104.

[0072] Line 400 can use conventional wires. The main purpose of line 400 is to supply power to liquid pump 200.

[0073] In this embodiment, after the liquid pump 200 is running, the liquid in the reservoir can enter the liquid pump 200 through the inlet 102, the pipeline 300 and the liquid pump inlet, and be pumped out of the liquid pump assembly through the liquid pump outlet, the pipeline 300 and the outlet 103, so that the liquid pump assembly can form a liquid flow, thereby realizing the basic function of the liquid pump assembly. In this hydraulic pump assembly, both the hydraulic pump 200 and the pipeline 300 can be housed in the receiving cavity 101 of the hydraulic pump assembly housing 100. Specifically, the hydraulic pump 200 is housed in the hydraulic pump cavity 101a, and the pipeline 300 is housed in the peripheral cavity 101b. Since the peripheral cavity 101b is located on at least one side of the hydraulic pump cavity 101a, the pipeline 300 can make full use of the peripheral space of the hydraulic pump 200 for arrangement, which can reduce the overall volume of the receiving cavity 101. This is beneficial for controlling the size of the hydraulic pump assembly housing 100, so that the hydraulic pump assembly housing 100, the hydraulic pump 200, and the pipeline 300 can form a highly integrated hydraulic pump assembly. When installing the hydraulic pump assembly, it is only necessary to install the hydraulic pump assembly housing 100 in the designated position, thereby achieving the purpose of saving vehicle interior space, reducing installation difficulty, and improving installation efficiency.

[0074] In conjunction with the foregoing, the pump assembly housing 100 may include a base 110 and a cover 120. In some embodiments, please refer to... Figures 1 to 4 The liquid pump assembly housing 100 may include a bottom wall 111, a first enclosure wall 112 disposed on the bottom wall 111, and a second enclosure wall 113 disposed on the bottom wall 111. Specifically, the bottom wall 111, the first enclosure wall 112, and the second enclosure wall 113 may be formed on the base 110. The first enclosure wall 112 forms a liquid pump cavity 101a and is adapted to at least a portion of the outline of the liquid pump 200. The second enclosure wall 113 extends from the first enclosure wall 112 in a direction away from the liquid pump 200 and forms an outer cavity 101b. The liquid inlet 102 and the liquid outlet 103 are disposed on the second enclosure wall 113, and the line outlet 104 is disposed on the bottom wall 111.

[0075] The first enclosure 112 and the second enclosure 113 can be disposed at the edge of the bottom wall 111 and extend toward one side of the bottom wall 111. It is understood that the first enclosure 112 and the second enclosure 113 are two parts of a continuous wall structure. The first enclosure 112 and the second enclosure 113 are only for the convenience of description and do not mean that the first enclosure 112 and the second enclosure 113 are two independent structures. The bottom wall 111, the first enclosure 112, the second enclosure 113 and the cover 120 can form the receiving cavity 101 of the liquid pump assembly housing 100. The first enclosure 112 can form the liquid pump cavity 101a and the second enclosure 113 can form the outer cavity 101b.

[0076] It is understandable that because the first enclosure 112 is adapted to at least part of the contour of the liquid pump 200, the liquid pump cavity 101a can be adapted to the shape of the liquid pump 200. After the liquid pump 200 is installed in the liquid pump cavity 101a, the liquid pump cavity 101a can play a certain limiting role for the liquid pump 200. In addition, the volume of the liquid pump cavity 101a can also be minimized, which is conducive to reducing the overall volume of the receiving cavity 101, thereby helping to control the shape of the liquid pump assembly housing 100.

[0077] The second enclosure 113 extends from the first enclosure 112 in a direction away from the pump 200, so that the outer cavity 101b can surround at least one side of the pump cavity 101a, thereby allowing the layout of the pipeline 300 and the line 400 to be completed in a position adjacent to the pump cavity 101a, which is beneficial to the integrated design of the pump assembly.

[0078] It is understood that for the liquid pump 200, its liquid pump inlet and liquid pump outlet are usually located outside the liquid pump 200 and placed at one end of the liquid pump 200. In the above embodiment, the outer cavity 101b is wrapped around at least one side of the liquid pump cavity 101a to accommodate the positions of the liquid pump inlet and liquid pump outlet. By setting the liquid inlet 102 and liquid outlet 103 on the second enclosure wall 113, it is not only convenient to arrange the pipeline 300 between the liquid inlet 102 and the liquid pump inlet, and to arrange the pipeline 300 between the liquid outlet 103 and the liquid pump outlet, but also to shorten the length of the pipeline 300.

[0079] By setting the line outlet 104 on the bottom wall 111, the line 400 can be led out from another direction, which can prevent the wall line 400 and the pipe 300 from overlapping or interfering, which is beneficial to the arrangement of the pipe 300 and the line 400 in the peripheral cavity 101b.

[0080] In some embodiments, please refer to Figures 1 to 4 The second enclosure 113 includes a first enclosure portion 1131 located beside the first enclosure 112 and a second enclosure portion 1132 located in front of the first enclosure 112. The outer cavity 101b includes a first cavity 101b1 enclosed by the first enclosure portion 1131 and a second cavity 101b2 enclosed by the second enclosure portion 1132.

[0081] You can refer to this. Figure 2 The first enclosure 1131 is located on the left side of the pump chamber 101a, and the second enclosure 1132 is located on the front side of the pump chamber 101a. The first chamber 101b1 can utilize the space on the left side of the pump chamber 101a, and the second chamber 101b2 can utilize the space on the front side of the pump chamber 101a. By setting the outer chamber 101b to include the first chamber 101b1 and the second chamber 101b2, it is beneficial to control the shape of the pump assembly housing 100.

[0082] In some embodiments, please refer to Figures 1 to 4 The inlet 102 is formed on the first enclosure 1131, and the outlet 103 is formed on the second enclosure 1132. The inlet 102 and the outlet 103 can be arranged facing each other.

[0083] The liquid inlet 102 is located on the first enclosure 1131 and the liquid outlet 103 is located on the second enclosure 1132. This allows for full utilization of the outer cavity 101b for the arrangement of the pipeline 300. For example, the liquid inlet pipeline 310 can be arranged as close as possible to the first cavity 101b1, and the liquid outlet pipeline 320 can be arranged as close as possible to the second cavity 101b2. Furthermore, since the liquid inlet 102 and the liquid outlet 103 are arranged facing each other, the pipeline 300 can be arranged in a straight line while making full use of the outer cavity 101b, which is beneficial for the flow of liquid in the pipeline 300.

[0084] In some embodiments, please refer to Figures 1 to 4 The second enclosure 113 also includes a clearance portion 1133 located between the first enclosure portion 1131 and the second enclosure portion 1132, which retracts toward the receiving cavity 101.

[0085] It is understandable that the clearance part 1133 can avoid some obstacles to realize the installation of the hydraulic pump assembly. For example, when the hydraulic pump assembly is installed in a designated position in the vehicle, because the clearance part 1133 is provided, the hydraulic pump assembly can avoid the beams, pillars or functional components of the vehicle for installation, so that the hydraulic pump chamber 101a can make full use of the vehicle's extra space for assembly.

[0086] In some specific embodiments, please refer to Figure 2 A first connecting part 114 is provided on the clearance part 1133 in a direction away from the receiving cavity 101.

[0087] The first connecting portion 114 can extend away from the receiving cavity 101. By forming the first connecting portion 114 on the clearance portion 1133, the liquid pump assembly can be installed at a designated location.

[0088] Specifically, the first connecting part 114 may include a mounting hole 1141, which may be a threaded hole, and fasteners such as screws may be used to install the liquid pump assembly.

[0089] In some embodiments, please refer to Figure 1 and Figure 2 The outer wall of the liquid pump assembly housing 100 is provided with a second connecting part 115, which is also used to realize the installation of the liquid pump assembly at a designated position.

[0090] The structure of the second connecting part 115 can be designed with reference to the first connecting part 114. The number and specific position of the second connecting part 115 can be set according to actual needs. For example, there can be multiple second connecting parts 115, which are spaced apart along the circumference on the first enclosure wall 112 and / or the second enclosure wall 113.

[0091] In the above embodiments, the bottom wall 111, the first enclosure wall 112, the second enclosure wall 113, the first connecting part 114, and the second connecting part 115 can be integrally formed to form the base 110.

[0092] In some embodiments, please refer to Figures 1 to 4 The pump assembly housing 100 also includes a flow passage structure 116, which can be formed on the base 110. The flow passage structure 116 is connected between the first enclosure 112 and the first enclosure portion 1131 and extends in a direction away from the receiving cavity 101. A flow passage 1161 is formed inside the flow passage structure 116. One end of the flow passage 1161 is sealed and connected to the liquid inlet 102, and the other end of the flow passage 1161 is used to connect to the liquid reservoir.

[0093] The flow passage structure 116 has at least two functions: firstly, it enhances the connection strength between the first enclosure 112 and the first enclosure portion 1131; secondly, it facilitates connection with an external liquid reservoir.

[0094] Regarding the first aspect mentioned above, as can be seen from the foregoing, since the first enclosure portion 1131 is located on the left side of the pump chamber 101a, the first enclosure portion 1131 will expand to the left from the first enclosure wall 112. At this time, a corner will be formed between the first enclosure wall 112 and the first enclosure portion 1131. By connecting the flow passage structure 116 between the first enclosure wall 112 and the first enclosure portion 1131, the strength loss caused by the corner can be compensated.

[0095] Regarding the second aspect mentioned above, since the inside of the flow structure 116 has a flow channel 1161, which is formed by the solid structure of the flow structure 116, and the flow structure 116 can be integrally formed with the base 110, the flow structure 116 itself can also serve as a connecting structure and be connected to the liquid reservoir.

[0097] In some embodiments, please refer to Figure 2 , Figure 5 and Figure 6The flow structure 116 has a connector 1162 formed at the end of the flow channel 1161 away from the receiving cavity 101, which is used to connect with the liquid reservoir.

[0098] Specifically, the specific structure of the connector 1162 is not limited. Furthermore, the connector 116 can be formed by protruding from one side surface of the flow-through structure 116; preferably, the connector 116 can extend downwards from the bottom wall of the flow-through structure 116 (e.g., Figure 6 The surface of the back groove 1164 shown.

[0099] In some embodiments, please refer to Figure 2 The flow structure 116 includes a flow section 1163 and a groove 1164 disposed on at least one side of the flow section 1163, and the flow section 1163 forms a flow channel 1161.

[0100] By providing a groove 1164 on at least one side of the flow section 1163, it is convenient to integrally injection mold the flow structure 116 and the base 110, which is beneficial to stress release during the injection molding process and can prevent the flow structure 116 from deforming during the injection molding process.

[0101] In some embodiments, please refer to Figures 1 to 4 The pump assembly also includes a first pipe connector 500 disposed in the inlet 102, the first pipe connector 500 having a first connection end 510 located in the receiving cavity 101, the first connection end 510 being configured in a conical shape.

[0102] It is understandable that the first pipe joint 500 needs to form a seal with the liquid inlet 102. Therefore, a sealing ring or other structure can be provided on the outer wall of the first pipe joint 500.

[0103] Because the first pipe joint 500 has a conical first connecting end 510, a quick sealing connection can be achieved between the first pipe joint 500 and the pipeline 300.

[0104] In conjunction with the foregoing, in the embodiment where the overflow structure 116 is provided, the end of the first pipe joint 500 that is away from the first connection end 510 can be connected to the overflow channel 1161, and the two can be connected by a sealed connection.

[0105] In some embodiments, please refer to Figures 1 to 4 The pump assembly also includes a second connector 600 disposed in the outlet 103. The second connector 600 has a second connection end 610 located in the receiving cavity 101 and a third connection end 620 located outside the receiving cavity 101. The second connection end 610 and the third connection end 620 are configured in a conical shape.

[0106] It is understandable that the second pipe joint 600 needs to form a seal with the liquid outlet 103. Therefore, a sealing ring or other structure can be provided on the outer wall of the second pipe joint 600.

[0107] Because the second pipe connector 600 has a cylindrical second connecting end 610, a quick sealing connection can be achieved between the second pipe connector 600 and the pipe 300. Because the second pipe connector 600 has a conical third connecting end 620, a quick sealing connection can be achieved between the second pipe connector 600 and an external pipe. The external pipe can lead to a camera or lidar on the vehicle.

[0108] In some embodiments, please refer to Figures 1 to 4 The pump assembly also includes a plurality of wire harness assemblies 700 disposed in the peripheral cavity 101b, each wire harness assembly 700 having a wire harness channel in which the tubing 300 and / or wiring 400 are confined.

[0109] Understandably, the cable routing channel can be adapted to the shape of the conduit 300 or the line 400, so that the cable routing assembly 700 can restrict the conduit 300 or the line 400.

[0110] By arranging the wiring harness assembly 700, the routing of the conduit 300 and / or the line 400 can be standardized, and the vibration of the conduit 300 and / or the line 400 in the peripheral cavity 101b can also be prevented.

[0111] The number of wire harness assemblies 700 in this embodiment is as follows: for example, there can be multiple wire harness assemblies 700, which can be arranged at intervals along the routing direction of the conduit 300 and the line 400.

[0112] This application does not limit the specific structure of the wire harness assembly 700. For example, the wire harness assembly 700 can be integrally formed with the base 110, or it can be formed separately and then installed into the peripheral cavity 101b by mechanical connection. The wire harness assembly 700 can be a clamp, elastic buckle, or locking ring, etc.

[0113] In some embodiments, please refer to Figures 1 to 4 The cable assembly 700 includes two opposing and spaced-apart posts 710, the distance between the two posts 710 being adapted to the outer diameter of the conduit 300 and / or the distance between the two posts 710 being adapted to the outer diameter of the line 400.

[0114] The column 710 can be integrally formed with the base 110. The column 710 can protrude from the bottom surface of the receiving cavity 101 to a certain height. The two columns 710 can clamp the pipe 300 or the line 400, thereby restricting the pipe 300 or the line 400.

[0115] In some specific embodiments, please refer to Figure 3 The cable harness assembly 700 also includes a crossbeam 720 connected to the column 710, and the bottom surfaces of the column 710, the crossbeam 720, and the peripheral cavity 101b form a cable harness channel.

[0116] The crossbeam 720 and the column 710 can form a closed cable bundle channel, which facilitates the passage of the conduit 300 or the line 400 through the cable bundle channel and completes the limiting.

[0117] In some specific embodiments, elastic pads or other structures can be provided on the inner side of the column 710 or the beam 720, so that the elastic pads can compress the pipe 300 or the line 400 to a certain extent, thereby enhancing the restrictive effect of the wire harness assembly 700 on the pipe 300 or the line 400.

[0118] As can be seen from the above embodiments, the liquid pump assembly in this application embodiment, based on the configuration of related structures such as the base 110, cover 120, pipeline 300, line 400, and liquid pump 200, enables the liquid pump assembly to generate liquid flow and spray the liquid flow to a designated location. Furthermore, because the related structures of the base 110 and cover 120 in this application embodiment are designed, the volume of the receiving cavity 101 can be reduced as much as possible while accommodating the liquid pump 200, pipeline 300, and line 400, thereby facilitating the formation of a compact and highly integrated liquid pump assembly.

[0119] As can be seen from the above embodiments, the housing of the liquid pump assembly in this application embodiment may include a base and a cover, which can form a sealed connection. In addition, the first pipe joint and the second pipe joint can also be sealed to the housing of the liquid pump assembly. Furthermore, in some embodiments, a sealing plug or other structure can be provided at the outlet hole to achieve the sealing of the circuit. The above-mentioned sealing designs can form a sealed receiving cavity in the housing of the liquid pump assembly, thereby enabling the liquid pump assembly to have excellent sealing performance and realize the normal use of the liquid pump assembly in special environments such as underwater environments.
