Description

Technical Field

[0001] This application relates to the field of water quality testing technology, and in particular to a water quality testing device and a water quality testing module. Background Technology

[0002] In the field of water quality testing, water quality testing modules are widely used in various scenarios, including pool cleaning robots, industrial equipment, and other machines and equipment used for water quality testing.

[0003] In practical use, water quality testing modules are typically installed in specific locations on the aforementioned equipment for continuous or periodic water quality analysis. However, traditional installation methods usually involve mounting the water quality testing module to the equipment using fixing bolts. While this method achieves basic fixation, it has several shortcomings in practical applications. For example, tools are required for both installation and removal of the water quality testing module, making the process cumbersome, time-consuming, and labor-intensive. Especially in environments requiring frequent disassembly and maintenance, this traditional installation method significantly increases operational complexity and maintenance costs. Utility Model Content

[0004] According to the first aspect disclosed in this application, a water quality testing device is provided, including a device body and a water quality testing module. The water quality testing module includes a testing body and a first connecting portion, the testing body and the first connecting portion being rotatably connected. The first connecting portion is at least partially located on the outer periphery of the testing body and is configured to allow circumferential rotation about the axis of the water quality testing module. The device body has an installation space, and the inner wall of the installation space has a second connecting portion. The water quality testing module is installed in the installation space through the first connecting portion and the second connecting portion. During the connection between the second connecting portion and the first connecting portion, the first connecting portion drives the testing body to move axially.

[0005] Furthermore, the outer wall of the detection body is provided with a first limiting part, and the inner wall of the installation space is also provided with a second limiting part. The docking of the first limiting part and the second limiting part can limit the detection body in a circumferential direction.

[0006] Furthermore, the second limiting portion includes a limiting protrusion, and the first limiting portion includes a limiting groove adapted to the limiting protrusion, wherein the limiting protrusion and the limiting groove are slidable relative to each other along the axial direction of the detection body; or, the second limiting portion includes a limiting groove, and the first limiting portion includes a limiting protrusion adapted to the limiting groove, wherein the limiting protrusion and the limiting groove are slidable relative to each other along the axial direction of the detection body.

[0007] Furthermore, there are multiple first limiting parts, which are arranged sequentially along the circumference of the detection body, and the multiple first limiting parts are arranged non-centrally symmetrically. The number of second limiting parts is the same as that of the first limiting parts and they are arranged correspondingly.

[0008] Furthermore, the first connecting portion is sleeved on the outer periphery of the detection body, and the detection body and the first connecting portion are rotatably connected by a rotating protrusion and a rotating groove; the rotating protrusion is disposed on the detection body, and the rotating groove is disposed on the first connecting portion, or the rotating protrusion is disposed on the first connecting portion, and the rotating groove is disposed on the detection body.

[0009] Furthermore, the first connecting part and the second connecting part are threaded together.

[0010] Furthermore, the first connecting part is provided with a force-applying part, which can drive the first connecting part to rotate during the installation of the detection module.

[0011] Furthermore, the end of the detection body is provided with a first contact point, and the installation space is provided with a second contact point. When the water quality detection module is installed in the installation space, the first contact point and the second contact point abut against each other.

[0012] Furthermore, the water quality testing module also includes a sealing ring, which is fitted around the outer periphery of the testing body; when the first contact point and the second contact point abut, the sealing ring is connected to the inner wall of the installation space to form a sealed space at the first contact point and the second contact point.

[0013] According to a second aspect disclosed in this application, a water quality testing module is provided, which can be installed in the installation space of a water quality testing device. The water quality testing module includes a testing body and a first connecting part, the testing body and the first connecting part being rotatably connected. The first connecting part is at least partially located on the outer periphery of the testing body and is configured to allow circumferential rotation about the axis of the testing module. After the first connecting part is connected to a second connecting part disposed on the inner wall of the installation space, the water quality testing module can be installed in the installation space. During the connection between the first connecting part and the second connecting part, the second connecting part drives the testing body to move axially.

[0014] Furthermore, a first limiting part is provided on the outer periphery of the detection body, and when the first limiting part is connected to the second limiting part on the inner wall of the installation space, it can limit the detection body in the circumferential direction.

[0015] The embodiments described in this application have the following beneficial effects:

[0016] The water quality testing module includes a testing body and a first connecting part, which is circumferentially rotatable relative to the testing body around the axis of the water quality testing module. The first connecting part can mate with a second connecting part on the equipment body. During the connection process, the first connecting part provides an axial force to the testing body, thereby causing the testing body to move axially towards the installation space of the equipment body. After the first and second connecting parts are in place, they are relatively fixed, and the first connecting part provides radial and axial restraint to install the testing body within the installation space. When it is necessary to disassemble the water quality testing module, the first connecting part is detached from the second connecting part, causing the first connecting part to move the testing body axially away from the installation space, thus separating the water quality testing module from the equipment body. In this way, the water quality testing module can be disassembled and assembled using the compatible first and second connecting parts, reducing the use of specialized tools, simplifying the disassembly and assembly steps, and lowering operational complexity and maintenance costs.

[0030] The technical solutions in this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0031] This application provides a water quality testing device 20, such as... Figures 1 to 5 As shown, the water quality testing device 20 includes a main body 21 and a water quality testing module 10. The water quality testing module 10 includes a testing body 100 and a first connecting part 200. The testing body 100 and the first connecting part 200 are rotatably connected. The first connecting part 200 is at least partially located on the outer periphery of the testing body 100 and is configured to allow circumferential rotation about the axis of the water quality testing module 10. Please refer to [the diagram / reference needed]. Figure 6 The main body of the equipment 21 is provided with an installation space 201, and the inner wall of the installation space 201 is provided with a second connecting part 22.

[0032] The water quality testing module 10 is installed in the installation space 201 via the first connecting part 200 and the second connecting part 22. During the process of connecting the second connecting part 22 with the first connecting part 200, the first connecting part 200 drives the testing body 100 to move axially.

[0033] The detection body 100 and the first connecting part 200 are rotatably connected. At least a portion of the first connecting part 200 is located on the outer periphery of the detection body 100, and the first connecting part 200 is circumferentially rotatable about the axis of the water quality detection module 10. Figure 2As shown, the installation space 201 may have an opening, and the first connecting part 200 and the second connecting part 22 can be detachably connected. During the connection process, the first connecting part 200 drives the detection body 100 to move axially in a first direction, so that the detection body 100 can be moved into the installation space 201 through the opening. When the first connecting part 200 and the second connecting part 22 are in place, the installation of the water quality detection module 10 in the installation space 201 is completed. During the disassembly process, the first connecting part 200 drives the detection body 100 to move axially in a direction opposite to the first direction, so that the detection body 100 can be moved out of the installation space 201 through the opening, thereby realizing the disassembly of the water quality detection module 10.

[0034] After the water quality testing module 10 is installed, the second connecting part 22 can radially and axially limit the first connecting part 200, thereby radially and axially limiting the water quality testing module 10. Furthermore, since the first connecting part 200 can rotate circumferentially around the axis of the water quality testing module 10, during the connection or disassembly of the first connecting part 200 and the second connecting part 22, the first connecting part 200 does not need to drive the testing body 100 to rotate circumferentially, improving the axial positioning accuracy of the testing body 100 and facilitating the docking of the contacts of the testing body 100 and the contacts of the device body 21. For example, the first connecting part 200 and the second connecting part 22 can be connected by at least one of the following detachable connection methods: screw connection, threaded connection, and sliding snap-fit ​​connection.

[0035] In the case where the water quality testing module 10 is installed in the installation space 201, the first connection part 200 is located at the opening of the installation space 201, and part of the first connection part 200 is located outside the installation space 201, so that the user can disassemble and assemble the first connection part 200 through the part of the first connection part 200 located outside the installation space 201, thereby improving the convenience of operation.

[0036] In this way, the water quality testing module 10 can be installed and disassembled without the need for professional tools through the matching first connecting part 200 and second connecting part 22, thereby enabling the water quality testing module 10 to be maintained and replaced. This simplifies the disassembly and assembly steps of the water quality testing module 10, improves the speed and convenience of disassembly and assembly, and reduces the complexity of operation and maintenance costs.

[0037] For example, such as Figure 2 and Figure 3 As shown, the first connecting part 200 can be threadedly connected to the second connecting part 22.

[0038] For example, the first connecting part 200 may be provided with an external thread, and the second connecting part 22 may be provided with an internal thread, with the external thread and the internal thread being compatible. Alternatively, the first connecting part 200 may be provided with an internal thread, and the second connecting part 22 may be provided with an external thread, with the internal thread and the external thread being compatible.

[0039] Figure 2 This is a cross-sectional structural diagram showing the connection process between the first connecting part 200 and the second connecting part 22, as shown below. Figure 2 As shown, during the connection process between the first connecting part 200 and the second connecting part 22, the first connecting part 200 can be driven to rotate around the detection body 100 in the second direction. Through the cooperation of the "internal thread" and the "external thread", the first connecting part 200 can not only rotate circumferentially relative to the inner wall of the installation space 201, but also move along the axial direction of the detection body 100 toward the installation space 201. Thus, the first connecting part 200 can provide an axial force to the detection body 100, thereby driving the detection body 100 to move axially toward the installation space 201.

[0040] Figure 3 This is a cross-sectional structural diagram of the first connecting part 200 and the second connecting part 22 after they are connected in place, as shown below. Figure 3 As shown, after the first connecting part 200 and the second connecting part 22 are connected in place, the first connecting part 200 and the second connecting part 22 are relatively fixed. The first connecting part 200 can radially and axially limit the detection body 100 to install the detection body 100 in the installation space 201. When it is necessary to disassemble the water quality detection module 10, the first connecting part 200 can be rotated around the detection body 100 in a direction opposite to the second direction, so that the first connecting part 200 moves along the axial direction of the detection body 100 in a direction away from the installation space 201. This allows the first connecting part 200 to drive the detection body 100 to move axially in a direction away from the installation space 201, thereby separating the water quality detection module 10 from the equipment body 21. In this way, the water quality detection module 10 can be disassembled and assembled by rotating the first connecting part 200, reducing the use of professional tools, simplifying the disassembly and assembly steps of the water quality detection module 10, and reducing the complexity of operation and maintenance costs.

[0041] This not only improves the connection stability between the first connecting part 200 and the second connecting part 22, but also provides an axial component force to the detection body 100 when the first connecting part 200 rotates, thereby driving the detection body 100 to move axially and improving the accuracy of the axial positioning of the detection body 100 when the water quality detection module 10 is installed.

[0042] Figure 4 A schematic diagram of a partial radial cross-sectional structure of a water quality testing device is shown, exemplarily, as follows: Figure 2 and Figure 4As shown, the outer wall of the detection body 100 is provided with a first limiting part 110, and the inner wall of the installation space 201 is also provided with a second limiting part 23. The docking of the second limiting part 23 and the first limiting part 110 can limit the detection body 100 in the circumferential direction.

[0043] During the connection process between the first connecting part 200 and the second connecting part 22, the first connecting part 200 drives the detection body 100 to move axially, so that the second limiting part 23 of the installation space 201 can dock with the first limiting part 110 of the detection body 100, thereby restricting the circumferential rotation of the detection body 100. The first limiting part 110 and the second limiting part 23 can be connected by at least one of the following detachable connection methods: snap-fit, pin connection, key connection, and magnetic connection.

[0044] In this way, through a set of compatible connecting parts (i.e., the first connecting part 200 and the second connecting part 22) and a set of limiting parts (the first limiting part 110 and the second limiting part 23), the water quality detection module 10 is limited in three degrees of freedom: axial, radial, and circumferential. This reduces the occurrence of offset or misalignment of the detection body 100 during assembly and disassembly, and also reduces wear between the rotation of the detection body 100 and the inner wall of the installation space 201, thereby improving the stability and reliability of the water quality detection module 10 installation. Simultaneously, it also ensures the accuracy and stability of the contact connection between the equipment body 21 and the water quality detection module 10.

[0045] The second limiting part 23 may include, for example, a limiting protrusion, and the first limiting part 110 may include a limiting groove adapted to the limiting protrusion. The limiting protrusion and the limiting groove can slide relative to each other along the axial direction of the detection body 100.

[0046] When the water quality testing module 10 is installed inside the main body 21 of the equipment, the limiting protrusion is located in the limiting groove to circumferentially limit the water quality testing module 10, reduce the shaking or displacement of the testing body 100, and improve the stability and accuracy of the installation of the water quality testing module 10.

[0047] The limiting protrusion and the limiting groove can extend along the axial direction of the water quality detection module 10, so that during the installation or removal of the water quality detection module 10, the limiting protrusion can slide relative to the limiting groove along the axial direction of the detection body 100, so that the water quality detection module 10 can be smoothly moved into or out of the installation space 201.

[0048] like Figure 4 As shown, the second limiting part 23 may include, for example, a limiting groove 203, and the first limiting part 110 may include a limiting protrusion 111 adapted to the limiting groove 203. The limiting protrusion 111 and the limiting groove 203 can slide relative to each other along the axial direction of the detection body 100.

[0049] When the water quality testing module 10 is installed inside the main body 21 of the equipment, the limiting protrusion 111 is located in the limiting groove 203 to circumferentially limit the water quality testing module 10, reduce the shaking or displacement of the main body 100, and improve the stability and accuracy of the installation of the water quality testing module 10.

[0050] The limiting protrusion 111 and the limiting groove 203 can extend along the axial direction of the water quality detection module 10, so that during the installation or removal of the water quality detection module 10, the limiting groove 203 can slide relative to the limiting protrusion 111 along the axial direction of the detection body 100, so that the water quality detection module 10 can be smoothly moved into or out of the installation space 201.

[0051] It is understood that the above-described configuration of the second limiting part 23 and the first limiting part 110 is merely exemplary. The specific configuration of the second limiting part 23 and the first limiting part 110 can be based on the specific structure of the water quality testing equipment 20 or on the experience of those skilled in the art, and is not specifically limited here.

[0052] For example, such as Figure 4 As shown, there are multiple first limiting parts 110, which are arranged sequentially along the circumference of the detection body 100, and are arranged non-centrally symmetrically. The number of second limiting parts 23 is the same as that of the first limiting parts 110 and they are arranged accordingly.

[0053] Multiple first limiting parts 110 are arranged sequentially along the circumference of the detection body 100. The number of second limiting parts 23 is the same as that of the first limiting parts 110 and they are arranged accordingly. By cooperating and docking the multiple second limiting parts 23 and the first limiting parts 110, the limiting force on the detection body 100 can be increased, the limiting effect on the detection body 100 can be improved, and the occurrence of separation between the second limiting parts 23 and the first limiting parts 110 can be reduced.

[0054] Furthermore, the multiple first limiting parts 110 are arranged non-centrally and symmetrically. In this way, when the multiple second limiting parts 23 are respectively connected to the corresponding first limiting parts 110, they can provide a prompt for the placement of the detection body 100, so that the detection body 100 has only one way of being placed in the installation space 201. This reduces the occurrence of the first contact 103 and the second contact 24 being offset from each other or even misaligned, and improves the installation accuracy of the water quality detection module 10.

[0055] For example, such as Figure 4As shown, there are three second limiting parts 23 and three first limiting parts 110. There is an extension arc between any two adjacent second limiting parts 23, and at least two of these extension arcs are different. This allows the user to identify the corresponding second limiting parts 23 and first limiting parts 110 by their different extension arcs, improving the accuracy of the docking between the corresponding second limiting parts 23 and first limiting parts 110, thereby improving the installation accuracy of the water quality testing module 10. It is understood that the above description of the number and position of the second limiting parts 23 and first limiting parts 110 is merely exemplary. The specific number and position of the second limiting parts 23 and first limiting parts 110 can be set according to the specific specifications of the water quality testing equipment 20, or according to the experience of those skilled in the art, as long as the error-proof positioning function during installation is achieved. No specific limitations are made here.

[0056] For example, such as Figure 3 , Figure 5 and Figure 6 As shown, the end of the detection body 100 is provided with a first contact 103, and the installation space 201 is provided with a second contact 24. When the water quality detection module 10 is installed in the installation space 201, the first contact 103 and the second contact 24 abut against each other.

[0057] The detection module 100 and the device body 21 can be connected communicatively and / or electrically via the first contact 103 and the second contact 24. Through the first contact 103 and the second contact 24, the water quality detection module 10 can transmit the detected water quality information to the device body 21 for subsequent operations (e.g., determining whether the water quality in the pool meets the requirements). Alternatively, through the first contact 103 and the second contact 24, the device body 21 can supply power to the water quality detection module 10, enabling the detection module 100 to perform water quality detection operations.

[0058] With a first contact 103 at the end of the detection body 100 and a second contact 24 within the installation space 201, the second limiting part 23 and the first limiting part 110 can circumferentially position the detection body 100 when the water quality detection module 10 is placed into the installation space 201, aligning the first contact 103 with the second contact 24. Furthermore, the circumferential limiting reduces the offset between the first contact 103 and the second contact 24 after the water quality detection module 10 is installed, thereby reducing the adjustment and calibration steps required when the first contact 103 and the second contact 24 come into contact, and improving the installation speed and accuracy of the water quality detection module 10.

[0059] like Figure 5As shown, the first connecting part 200 is sleeved on the outer periphery of the detection body 100, and the detection body 100 and the first connecting part 200 are rotatably connected by the rotating protrusion 210 and the rotating groove 120.

[0060] The first connecting portion 200 is fitted onto the outer periphery of the detection body 100, allowing the first connecting portion 200 to connect with the second connecting portion 22 on the inner wall of the installation space 201. The portion of the outer wall of the detection body 100 not fitted with the first connecting portion 200 may be provided with a first limiting portion 110.

[0061] The rotating protrusion 210 can be disposed within the rotating groove 120, allowing it to rotate circumferentially within the groove. The groove 120 also provides axial restraint for the protrusion 210, reducing the likelihood of separation between the first connecting portion 200 and the detection body 100, thus improving the stability and reliability of the water quality detection module 10. Furthermore, during the connection process between the first connecting portion 200 and the second connecting portion 22, the first connecting portion 200 can provide an axial force to the detection body 100 through the sidewall of the rotating groove 120 that abuts against the rotating protrusion 210, thereby driving the detection body 100 to move axially.

[0062] For example, a rotating protrusion is provided on the detection body 100, and a rotating groove is provided on the first connecting part 200, or, as... Figure 2 and Figure 3 As shown, a rotating protrusion 210 is provided on the first connecting part 200, and a rotating groove 120 is provided on the detection body 100.

[0063] Taking a rotating protrusion 210 located on the first connecting part 200 and a rotating groove 120 located on the detection body 100 as an example, the rotating protrusion 210 is located on the inner side wall of the first connecting part 200 and the rotating groove 120 is located on the outer side wall of the detection body 100. The detection body 100 may include a first housing 101 and a second housing 102. The first housing 101 and the second housing 102 are detachably connected, and the first housing 101 and the second housing 102 together enclose the rotating groove 120. In this way, when assembling the water quality testing module 10, the first connecting part 200 can be sleeved on the outside of the first housing 101, and along the axial direction of the testing body 100, the rotating protrusion 210 is located on one side of the first housing 101. Then, the second housing 102 is connected to the first housing 101 from one side. At this time, the second housing 102 can form a rotating groove 120 with the first housing 101, and the rotating protrusion 210 is located in the rotating groove 120. This arrangement can smoothly place the rotating protrusion 210 in the rotating groove 120, and the first connecting part 200 can be detachably installed on the testing body 100, which is convenient for replacing the first connecting part 200.

[0064] It is understood that the above-described connection method between the rotating protrusion 210 and the rotating groove 120 is merely exemplary. As long as the rotating protrusion 210 is located within the rotating groove 120 and the rotating protrusion 210 can rotate circumferentially relative to the rotating groove 120, the specific connection method between the rotating protrusion 210 and the rotating groove 120 is not limited here.

[0065] Instance-wise, such as Figure 2 , Figure 3 and Figure 5 As shown, the first connecting part 200 is provided with a force-applying part 220, which can drive the first connecting part 200 to rotate during the installation of the detection module. In this way, the user can drive the first connecting part 200 to rotate relative to the second connecting part 22 through the force-applying part 220, which facilitates user operation and improves the installation convenience of the water quality detection module 10.

[0066] After the water quality testing module 10 is installed, at least a portion of the first connecting part 200 can be located within the installation space 201, and at least a portion of the force-applying part 220 can extend out of the installation space 201 and be exposed outside the installation space 201. This allows the user to smoothly rotate the first connecting part 200 through the force-applying part 220 when disassembling the water quality testing module 10, improving the convenience of disassembling the water quality testing module 10 and the user's experience.

[0067] For example, the force-applying part 220 can extend radially along the detection body 100, so that the user can easily hold the force-applying part 220 and apply force. The force-applying part 220 smoothly applies circumferential force to the first connecting part 200, reducing the occurrence of slippage when the user rotates the first connecting part 200 and improving the disassembly efficiency of the water quality detection module 10. The force-applying part 220 may include, for example, a force-applying rod or a force-applying plate, which extends radially along the detection body 100.

[0068] It is understood that the above description of the force-applying part 220 is merely exemplary. The specific configuration of the force-applying part 220 can be based on the specific structure of the water quality detection module 10 or the experience of those skilled in the art. As long as the user can drive the first connecting part 200 to rotate through the force-applying part 220, the specific configuration of the force-applying part 220 is not specifically limited here.

[0069] For example, such as Figure 2 , Figure 3 and Figure 5 As shown, the water quality testing module 10 also includes a sealing ring 300, which is sleeved on the outer periphery of the testing body 100. When the first contact 103 and the second contact 24 abut, the sealing ring 300 connects to the inner wall of the mounting space 201 to form a sealed space at the first contact 103 and the second contact 24.

[0070] The first contact 103 and the second contact 24 can be connected for communication and / or electrical connection. When the first contact 103 and the second contact 24 abut, that is, after the water quality detection module 10 is installed in place, the sealing ring 300 of the water quality detection module 10 is connected to the inner wall of the installation space 201. The sealing ring 300 can seal the gap between the inner wall of the installation space 201 and the outer peripheral wall of the detection body 100, so that the space between the position of the sealing ring 300 and the end of the detection body 100 and the bottom wall of the installation space 201 is a sealed space. Thus, a sealed space is formed at the first contact 103 and the second contact 24, reducing the flow of liquid in the pool to the first contact 103 and the second contact 24, which may interfere with the connection between the first contact 103 and the second contact 24 or even cause a short circuit, thereby improving the safety and reliability of the water quality detection equipment 20.

[0071] It should be noted that the technical term "bottom wall of mounting space 201" refers to the inner wall of mounting space 201 opposite to the opening of mounting space 201.

[0072] This application provides a water quality testing module 10, which can be installed within the installation space 201 of a water quality testing device 20. The water quality testing module 10 includes a testing body 100 and a first connecting part 200, which are rotatably connected. The first connecting part 200 is at least partially located on the outer periphery of the testing body 100 and is configured to allow circumferential rotation about the axis of the testing module. After the first connecting part 200 is connected to a second connecting part 22 provided on the inner wall of the installation space 201, the water quality testing module 10 can be installed within the installation space 201. During the connection between the first connecting part 200 and the second connecting part 22, the second connecting part 22 drives the testing body 100 to move axially.

[0073] The water quality testing module 10 includes a testing body 100 and a first connecting part 200. The first connecting part 200 is circumferentially rotatable relative to the testing body 100 about the axis of the water quality testing module 10. The first connecting part 200 can be connected to a second connecting part 22 of the water quality testing device 20. During the connection process, the first connecting part 200 can provide an axial force to the testing body 100, thereby driving the testing body 100 to move axially toward the installation space 201 of the water quality testing device 20. After the first connecting part 200 and the second connecting part 22 are connected in place, the first connecting part 200 and the second connecting part 22 are relatively fixed. The first connection can limit the testing body 100 radially and axially to install the testing body 100 in the installation space 201. During the disassembly of the first connecting part 200 and the second connecting part 22, the first connecting part 200 drives the detection body 100 to move axially in a direction opposite to the first direction, so that the detection body 100 can be moved out of the installation space 201 through the opening of the installation space 201, thereby realizing the disassembly of the water quality detection module 10. In this way, the water quality detection module 10 can be disassembled and assembled simply by rotating the first connecting part 200, reducing the use of professional tools, simplifying the disassembly and assembly steps of the water quality detection module 10, and reducing the complexity of operation and maintenance costs.

[0074] For example, a first limiting part 110 is provided on the outer periphery of the detection body 100. When the first limiting part 110 is connected to the second limiting part 23 on the inner wall of the installation space 201, it can limit the detection body 100 in the circumferential direction.

[0075] During the connection process between the first connecting part 200 and the second connecting part 22, the first connecting part 200 drives the detection body 100 to move axially, so that the second limiting part 23 of the installation space 201 can dock with the first limiting part 110 to restrict the detection body 100 from rotating circumferentially with the first connecting part 200.

[0076] In this way, through a set of compatible connecting parts (i.e., the first connecting part 200 and the second connecting part 22) and a set of limiting parts (the first limiting part 110 and the second limiting part 23), the water quality detection module 10 is limited in three degrees of freedom: axial, radial, and circumferential. This reduces the occurrence of offset or misalignment of the detection body 100 during assembly and disassembly, and also reduces wear between the rotation of the detection body 100 and the inner wall of the installation space 201, thereby improving the stability and reliability of the water quality detection module 10 installation. Simultaneously, it also ensures the accuracy and stability of the contact connection between the equipment body 21 and the water quality detection module 10.

[0077] The water quality testing module 10 provided in this application can be the water quality testing module 10 of the aforementioned water quality testing equipment 20. Therefore, the water quality testing module 10 provided in this application includes all the beneficial effects of the aforementioned water quality testing module 10, which will not be repeated here.
