Description
Technical Field
[0001] This application relates to the technical field of water quality testing equipment, and more particularly to a water quality testing module. Background Technology
[0002] With the increasing popularity of swimming pools, cleaning has become a crucial aspect of their use. Besides employing pool cleaning robots, water quality testing is also essential. Typical water quality testing devices use metal sealing rings for waterproofing, but these rings are difficult to remove, preventing existing equipment from supporting module replacement and hindering user customization of testing options. If plastic seals are used, the parting lines created during molding will compromise the waterproofing effect. Utility Model Content

The water quality testing module includes a main body and a sealing assembly. The sealing assembly is disposed at one end of the main body and includes a top cover, a sealing seat, and a sealing ring. The top cover and the sealing seat are axially installed, and the top cover and the sealing seat cooperate to form a groove for accommodating the sealing ring. When the water quality testing module is detachably installed on the water quality testing device, the sealing ring makes radial contact with the water quality testing device and prevents external water from contacting the top cover.
[0004] Furthermore, the first end of the sealing seat is connected to the upper cover, and the second end of the sealing seat is connected to the main body.
[0005] Furthermore, a connecting structure is provided between the upper cover and the sealing seat to ensure a tight connection between the upper cover and the sealing seat.

[0007] Furthermore, the upper cover is provided with a connection channel that extends through the upper cover, allowing at least a portion of the circuit terminals to pass through the upper cover.
[0008] Furthermore, the connection structure includes: threaded connection, snap-fit connection, adhesive bonding, locking connection, or welding.
[0009] Furthermore, the connection channel includes: a threaded interface, a snap-fit interface, or a combination interface.
[0010] Furthermore, the top cover, the sealing seat, and the sealing ring are made of plastic material.
[0011] This application also provides a water quality testing device, including a water quality testing module as described in any one of the above-mentioned methods.
[0012] Furthermore, the water quality testing equipment includes an abutment plate, wherein when the water quality testing module is detachably installed in the water quality testing equipment, the abutment plate radially surrounds the sealing ring and is in interference fit with the sealing ring.
[0013] The embodiments described in this application have the following beneficial effects: The water quality testing module with a special sealing structure provided in this application allows users to freely disassemble and assemble the module, and can be installed according to the user's needs, making it applicable to more scenarios. Users do not need to purchase multiple different types of water quality testing equipment, and if the water quality testing module is damaged, users can disassemble and repair only the water quality testing module, improving operational flexibility and reducing costs. The special sealing structure of the water quality testing module enhances waterproof performance on the basis of being removable, which not only improves user experience but also ensures user safety during operation.

[0017] The embodiments of this disclosure will now be described with reference to the accompanying drawings. The described embodiments are merely some, not all, of the embodiments described herein. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the protection scope of this application. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.
[0018] This application provides a water quality testing module 10, which is detachably installed on a water quality testing device 20. The water quality testing module 10 includes a main body 11 and a sealing assembly 12. The sealing assembly 12 is disposed on the upper end of the main body 11. The sealing assembly 12 includes an upper cover 121, a sealing seat 122, and a sealing ring 123. The upper cover 121 and the sealing seat 122 are axially installed, and the upper cover 121 and the sealing seat 122 cooperate to form a groove for accommodating the sealing ring 123. When the water quality testing module 10 is detachably installed on the water quality testing device 20, the sealing ring 123 makes radial contact with the water quality testing device 20 and prevents external water from contacting the upper cover 121. The water quality testing module 10 of this application will be described below with reference to the accompanying drawings.
[0019] like Figure 1 and Figure 2 As shown, the water quality testing module 10 is housed within the cavity of the water quality testing device 20. The water quality testing module 10 is the core component of the water quality testing device 20, used to measure various parameters in the water (such as pH, alkalinity, residual chlorine, temperature, total hardness, TDS, ORP, salinity, etc.). The water quality testing module 10 is detachably installed in the water quality testing device 20, allowing users to easily and conveniently replace different water quality testing modules 10 when different water quality parameters need to be tested, eliminating the need to purchase multiple water quality testing devices 20. Alternatively, if the water quality testing module 10 is damaged, it can be removed for replacement or repair. The detachable water quality testing module 10 improves operational flexibility and simplifies operation, further reducing maintenance costs and saving time.
[0020] Figure 1 and Figure 2 The position of the water quality testing module 10 within the cavity of the water quality testing equipment 20 shown is merely exemplary. This application does not impose specific limitations on the arrangement of the water quality testing module 10 within the cavity of the water quality testing equipment 20, as long as the technical principles of this application can be achieved.
[0021] like Figure 3As shown, the water quality detection module 10 includes a main body 11 and a sealing assembly 12. The outer shell of the main body 11 is made of a waterproof and insulating material (e.g., plastic). The outer shell of the main body 11 provides support, protection, and insulation for the various components inside the water quality detection module 10 (e.g., water quality sensors), ensuring that the internal motor, sensors, and control board will not short-circuit and leak electricity when the water quality detection module 10 is exposed to water during cleaning operations, thus ensuring user safety.
[0022] like Figure 2 and Figure 3 As shown, the sealing assembly 12 is disposed on the main body 11. The sealing assembly 12 includes a top cover 121, a sealing seat 122, and a sealing ring 123. The sealing ring 123 is an important component of the sealing assembly 12 that contributes to its waterproof effect. The sealing ring 123 can, for example, be disposed between the top cover 121 and the sealing seat 122. Figure 4 and Figure 5 As shown, the sealing ring 123 is a hollow ring that tightly wraps between the upper cover 121 and the sealing seat 122, preventing water from seeping into the upper part of the upper cover 121 through the gap at the connection between the upper cover 121 and the sealing ring 123. This also prevents water from contacting the components protected by the sealing assembly 12, such as preventing water from contacting the circuit terminals 13, and also prevents water from seeping into the water quality testing equipment 20. The upper cover 121 and the sealing seat 122 house the sealing ring 123, ensuring that the sealing ring 123 does not change its position relative to the upper cover 121 and the sealing seat 122 due to external factors such as impact, thus preventing the sealing assembly 12 from losing its waterproof effect.
[0023] like Figure 4 and Figure 5 As shown, the top cover 121 can be a circular component, for example. The top cover 121 has an annular protrusion structure along its circumference. The top cover 121 has a plurality of channels penetrating the top cover 121 (which will be described in detail below) in the middle. The top cover 121 can be connected to the water quality testing equipment 20 through the above channels.
[0024] Figure 5 The number of channels shown is merely an example. This application does not limit the number of channels in the middle of the top cover 121. Those skilled in the art can design according to the actual situation, as long as the technical principles of this application can be realized.
[0025] The sealing seat 122 can be cylindrical in shape, for example. Alternatively, the sealing seat 122 can have a concentric stepped structure, composed of multiple rings of different diameters stacked layer by layer. The sealing seat 122 gradually narrows from the bottom upwards, forming a stepped outer contour, and has a recess in the middle. The sealing seat 122 cooperates with the sealing ring 123 and the upper cover 121 to form a sealing assembly 12.
[0026] The upper cover 121 can be axially installed with the sealing seat 122, for example. Axial installation ensures that the upper cover 121 and the sealing seat 122 are perpendicularly connected, avoiding tilting. The upper cover 121 can also cooperate with the sealing seat 122 to form a groove for accommodating the sealing ring 123. This groove prevents the sealing ring 123 from shifting excessively or even falling off when compressed, achieving the fixing effect described above. The groove for accommodating the sealing ring 123 can also be formed on the outer wall of the sealing seat 122. The groove for accommodating the sealing ring 123 can also be formed on the outer wall of the upper cover 121.
[0027] When the water quality testing module 10 is detachably installed on the water quality testing device 20, the sealing ring 123 is in radial contact with the water quality testing device 20 (e.g., the inner wall of the mounting structure of the water quality testing device 20). This radial contact allows the sealing ring 123 to be radially compressed. In other words, the sealing ring 123 can, for example, be in close contact with the inner wall of the mounting structure of the water quality testing device 20 in the radial direction, thereby improving the waterproofing effect and preventing water from entering the upper part of the water quality testing device 20 and damaging the circuitry and other components on the upper part of the water quality testing device 20.
[0028] When the sealing component 12 is demolded as a single structure, if it is demolded from the left or right, a longitudinal parting line will be created, affecting the waterproofing effect of the sealing component 12. To avoid this, this application separates the sealing component 12 into an upper cover 121 and a sealing seat 122, which are demolded from the top and bottom respectively. This avoids the formation of a longitudinal parting line, thereby preventing water from penetrating through the sealing ring 123 via the longitudinal parting line. Figure 1 and Figure 2 The situation inside the water quality testing device 20 shown improves the waterproof performance of the sealing assembly 12.
[0029] The top cover 121, the sealing seat 122, and the sealing ring 123 are made of plastic material. Examples of plastic materials include polypropylene, polyvinyl chloride, and polyphenylene sulfone. Plastic materials are inexpensive, insulating, and waterproof. The sealing assembly 12 made of plastic material in this application extends the service life of the water quality testing equipment 20 and ensures user safety.
[0030] The first end of the sealing seat 122 is connected to the upper cover 121, and the second end of the sealing seat 122 is connected to the main body 11.
[0031] For example, such as Figure 4As shown, the first end of the sealing seat 122 is the upper end in the longitudinal direction, which is connected to the upper cover 121 to form the groove mentioned above. The groove is used to accommodate and fix the sealing ring 123. The second end of the sealing seat 122 is the lower end in the longitudinal direction, which is connected to the main body 11. The connection method between the second end and the main body 11 can be selected according to the actual situation. For example, a non-removable connection method such as welding, plugging, or riveting can be selected to avoid gaps caused by using a detachable connection method between the second end and the main body 11, which could allow water to seep into the interior of the main body 11 and damage the internal components. The sealing seat 122 connects the upper cover 121 and the main body 11 into a whole.
[0032] A connecting structure is provided between the upper cover 121 and the sealing seat 122, so that the upper cover 121 and the sealing seat 122 are connected in a sealed manner.
[0033] When assembling the upper cover 121 and the sealing seat 122, a connecting structure is required. This connecting structure ensures a tight seal between the upper cover 121 and the sealing seat 122, preventing external liquids from entering the sealing assembly 12 and further enhancing its waterproofness. The connecting structure may include, for example, screw fastening, threaded connection, snap-fit connection, adhesive bonding, locking connection, or welding.
[0034] The screw fastening connection allows the top cover 121 and the sealing seat 122 to be locked together with screws, which is stable and secure.
[0035] The threaded connection can mechanically connect the top cover 121 and the sealing seat 122 through the threaded structure. The threaded connection is a detachable connection method.
[0036] The snap-fit connection utilizes the elastic deformation of materials or structural design to allow the top cover 121 and the sealing seat 122 to interlock through a "click" structure, forming a stable connection. The snap-fit connection is characterized by being detachable and low-cost.
[0037] The cover 121 and the sealing seat 122 can be firmly bonded together using an adhesive. An example adhesive such as acrylic glue can be used.
[0038] Locking connections achieve quick and secure fastening through a mechanical interlocking structure. Specific types of locking connections include push-button locks, rotary locks, and sliding locks. Locking connections combine the convenience of snap-fit connections with the stability of threaded connections.
[0039] Welding involves heating and pressurizing the upper cover 121 and the sealing seat 122 to melt or plastically deform at the joint, thereby forming a metallurgical bond or molecular fusion. Commonly used welding methods include arc welding, resistance welding, and laser welding. The welded parts cannot be disassembled.
[0040] Those skilled in the art can choose the connection structure according to the actual situation. The above description of screw fixing connection, threaded connection, snap connection, adhesive, locking connection or welding is only exemplary and not an exhaustive list.
[0041] The water quality testing module 10 further includes a circuit terminal 13, at least a portion of which passes through the upper cover 121 and is connected to the water quality testing device 20.
[0042] Reference Figure 4 Circuit terminal 13 is a conductive component used for electrical connection, responsible for reliably connecting wires, PCBs, etc., to power supplies, loads, or other circuits. Circuit terminal 13 may be made of copper, aluminum, or plated materials (e.g., gold plating, tin plating) to reduce contact resistance. Circuit terminal 13 may be used to fix wires, for example, screw terminals tighten wires with screws, and plug-in terminals connect via male-female mating.
[0043] At least a portion of the circuit terminal 13 (e.g., the conductive portion of the circuit terminal 13) can pass through the top cover 121 and connect to the water quality testing device 20, for example, to the power supply component of the water quality testing device 20, providing power to the water quality testing module 10 so that the water quality testing module 10 can be used normally. The circuit terminal 13 and the water quality testing device 20 are detachably connected. As described above, the sealing ring 123 is in radial contact with the water quality testing device 20 (e.g., the inner wall of the mounting structure of the water quality testing device 20) and prevents external water from contacting the top cover 121, that is, the circuit terminal 13 can also be protected by the waterproof function of the sealing ring 123. The sealing ring 123 prevents external water from contacting the circuit terminal 13, making the circuit terminal 13 have a longer service life and safer use.
[0044] The upper cover 121 is provided with a connection channel that extends through the upper cover 121, allowing at least a portion of the circuit terminal 13 to pass through the upper cover 121.
[0045] like Figure 4 As shown, the upper cover 121 is provided with a connection channel. The upper cover 121 is connected to and fixes the circuit terminal 13 through the connection channel. The circuit terminal 13 is connected to the water quality testing device 20. The connection channel can be, for example, a through hole structure that penetrates the upper cover 121. The size of the through hole matches the circuit terminal 13. At least a part of the circuit terminal 13 (e.g., a conductive component) extends out from the channel and is electrically connected to the water quality testing device 20.
[0046] Furthermore, the connection channel includes: a threaded interface, a snap-fit interface, or a combination interface. The connection channel can be combined with the mechanical fixing part of the circuit terminal 13. For example, the connection channel can be a threaded interface, with standard threads (such as M3, M4, NPT, etc.) on the inner side of the channel, which can be rotated and fixed with the threaded circuit terminal 13; the connection channel can be a snap-fit interface, with elastic grooves or protrusions on the inner side of the channel, which can be combined with the snap-fit part (such as barbs, grooves, etc.) of the circuit terminal 13 for fixing; the connection channel can be a combination interface, with both threads and snap-fit structures on the inner side of the channel, for example, initially fixed by the snap-fit structure, and then further fixed by rotating the threaded part.
[0047] Those skilled in the art can choose the connection channel according to the actual situation. The above description of threaded interfaces, snap-fit interfaces or combination interfaces is only exemplary and not an exhaustive list.
[0048] This application also provides a water quality testing device 20, including a water quality testing module 10 as described in any one of the above-mentioned methods.
[0049] The water quality testing equipment 20 can float on the water surface or suspend in the water when in operation. The water quality testing equipment 20 includes any of the aforementioned water quality testing modules 10. The water quality testing equipment 20 can perform real-time or periodic water quality testing, allowing users to understand the water quality situation and take appropriate cleaning measures. The water quality testing module 10 has been described in detail above and will not be repeated here. (Refer to...) Figure 1 The water quality testing equipment 20 can be equipped with multiple water quality testing modules 10 to simultaneously test various water quality data, thereby improving the working efficiency of the water quality testing equipment 20 and optimizing the user experience. This application does not limit the number of water quality testing modules 10, as long as they can implement the technical principles of this application.
[0050] Furthermore, the water quality testing device 20 includes an abutment plate, in which the water quality testing module 10 is detachably installed on the water quality testing device 20, the abutment plate radially surrounds the sealing ring 123 and is in interference fit with the sealing ring 123.
[0051] The abutment plate can be made of, for example, metallic materials (such as stainless steel or titanium alloy), polymeric materials (such as rubber or polyetheretherketone), or composite materials. The abutment plate is corrosion-resistant, high-strength, not easily damaged, and has a long service life. When the water quality testing module 10 is detachably installed on the water quality testing equipment 20, gaps may exist at the connection between the water quality testing module 10 and the water quality testing equipment 20, leading to a reduction in the waterproof performance of the sealing assembly 12. To avoid this, an abutment plate is used to surround the sealing ring 123 and to make interference contact with the sealing ring 123. That is, when the water quality testing module 10 is installed on the water quality testing equipment 20, the abutment plate compresses the sealing ring 123, causing the sealing ring 123 to deform. The deformed sealing ring 123 tightly bonds with the abutment plate, improving the waterproof performance of the sealing assembly 12.
[0052] This application does not limit the material of the abutment plate or the degree of interference contact, as long as the technical principle of this application can be achieved.
[0053] The water quality testing module with a special sealing structure provided in this application allows users to freely disassemble and assemble the module, and can be installed according to the user's needs, making it applicable to more scenarios. Users do not need to purchase multiple different types of water quality testing equipment, and if the water quality testing module is damaged, users can disassemble and repair only the water quality testing module, improving operational flexibility and reducing costs. The special sealing structure of the water quality testing module enhances waterproof performance on the basis of being removable, which not only improves user experience but also ensures user safety during operation.
