Description

Technical Field

[0001] This invention relates to the field of urine testing technology, and in particular to an intelligent urine testing module and control method, and an intelligent toilet. Background Technology

[0002] Urine testing is an important method for diagnosing a person's health condition. It typically measures pH, protein, occult blood, specific gravity, glucose, ketones, urobilinogen, nitrates, white blood cells, bilirubin, and vitamin C, reflecting a range of health indicators. Urine testing is usually performed in hospitals, where patients often have to queue to register, see a doctor, pay fees, collect urine samples, and wait for results after batches of tests, which is time-consuming and laborious. Alternatively, dedicated urine analyzers can be purchased for home use, but the process requires manual collection, testing, and cleaning, which is cumbersome, prone to errors, and inefficient, making it unsuitable for elderly users or for the "seamless interaction" scenarios of smart homes.

[0003] In existing technologies, a solution has been developed to integrate urine testing functionality into toilets to address the aforementioned issues. This involves installing a urine testing module within the toilet bowl, collecting urine that comes into contact with test strips within the module, and interpreting and detecting the results based on the color of the test strips. However, this solution requires urine to enter the module during the testing process, which can easily contaminate the test strips. Furthermore, the testing chamber requires cleaning and drying after testing, resulting in a large urine testing module that occupies a significant amount of space. Summary of the Invention

[0004] To address the technical problems of existing toilet-built-in urine testing modules being bulky, susceptible to contamination, and providing limited test results, this invention provides an intelligent urine testing module, which includes a housing, an electrode box assembly, a push assembly, and an annular seal. The housing is provided with a detection port; An electrode box assembly is detachably installed in the housing, and the electrode box assembly contains a plurality of electrode plates arranged in a preset direction; A push component is movably disposed in the housing. The push component integrates a detection probe group, which is embedded in the front end face of the push component and can form an electrical connection with the detection circuit of the electrode plate through physical contact. The pushing component pushes the electrode sheet in the electrode box assembly to the preset position of the detection port along a preset path, and pushes the original electrode sheet located in the detection port away from the detection port at the same time as pushing the new electrode sheet into the detection port. The detection port is provided with an annular seal, and the surface of the annular seal that contacts the electrode is made of an elastic material. The elastic material deforms under pressure to achieve a seal between the detection port and the electrode.

[0005] Furthermore, the housing includes a first channel for placing a pushing component and communicating with the detection port, and a second channel for placing an electrode box assembly. The pushing component pushes the electrode sheet along a preset path in the extension direction of the first channel, and the electrode sheets in the electrode box assembly are stacked and arranged along the extension direction of the second channel. The extension direction of the first channel intersects with the extension direction of the second channel.

[0006] Furthermore, the annular seal has an inner annular cavity into which the electrode sheet can be embedded, and the cross-sectional area of ​​the inner annular cavity gradually decreases along its axial direction as it approaches the end face away from the push assembly.

[0007] Furthermore, it also includes a protective cover, which is detachably connected to the detection port; the protective cover extends to form a limiting portion on the end face near the push assembly, and the annular seal extends to form a limiting groove on the outer periphery of the end face near the push assembly; the limiting portion is embedded in the limiting groove to restrict the annular seal between the protective cover and the detection port; the protective cover has a through groove for exposing the electrode sheet located at the detection port to the protective cover.

[0008] Furthermore, the pushing component includes a pushing slider and a first driving member; the pushing slider is movably disposed within the housing, and the first driving member drives the pushing slider to reciprocate along a preset path to push the electrode sheet to a preset position of the detection port.

[0009] Furthermore, the pushing slider component includes a slider body, a detection circuit board, and a stylus fixing block. The detection stylus group is integrated on the detection circuit board. The detection stylus group includes a plurality of elastic needles arranged in an array for elastic contact with the electrode sheet. The stylus fixing block is connected to one end of the slider body near the detection port. The detection circuit board is fixed between the slider body and the stylus fixing block, and the detection stylus group on the detection circuit board passes through the stylus fixing block and is exposed on the front end face of the pushing component for contacting the electrode sheet.

[0010] Furthermore, it also includes a flipping component disposed between the electrode box assembly and the pushing component, used to flip the electrode sheet in the electrode box assembly onto the pushing component, so that the detection circuit contacts the detection stylus group; the flipping component includes a first claw, a second claw, a first transmission chuck, a second transmission chuck, a second driving member, and a third driving member, the first claw and the second claw being opposite to each other and spaced apart between the electrode box assembly and the pushing component; the first transmission chuck is connected to the first claw, the second transmission chuck is connected to the second claw, and the second driving member is respectively connected to the first transmission chuck and the second transmission chuck to drive the first transmission chuck and the second transmission chuck to move closer or further away from each other, thereby causing the first claw and the second claw to move closer or further away from each other to engage or disengage the electrode sheet, and the third driving member drives the first claw and the second claw to rotate by a preset angle to flip the electrode sheet in the electrode box assembly onto the front end face of the pushing component.

[0011] Furthermore, the second driving component includes a second motor, a bidirectional lead screw, and a threaded slider. The second motor is driven by the bidirectional lead screw. Each end of the bidirectional lead screw is threadedly connected to a threaded slider, and the two threaded sliders are respectively hinged to the first transmission chuck and the second transmission chuck. The first transmission chuck has a first driven tooth, and the second transmission chuck has a second driven tooth. The third driving component includes a third motor, a first driving tooth, and a second driving tooth. The first driving tooth meshes with the first driven tooth, and the second driving tooth meshes with the second driven tooth. The third motor drives the first driving tooth and the second driving tooth to rotate, thereby simultaneously driving the first jaw on the first transmission chuck and the second jaw on the second transmission chuck to rotate synchronously.

[0012] This invention also provides a control method for an intelligent urine testing module, which uses the intelligent urine testing module described in any of the above embodiments and further includes the following steps: When a urine test command is received, the pushing component pushes the electrode sheet in the electrode box assembly to the preset position of the detection port along a preset path, and at the same time as pushing the new electrode sheet into the detection port, pushes the original electrode sheet located in the detection port away from the detection port, so that the new electrode sheet is sealed by the annular seal. After the new electrode pad completes urine collection, the urine is detected by the detection circuit and the detection probe assembly.

[0013] This invention also provides an intelligent toilet that uses the intelligent urine detection module described in any of the above embodiments.

[0014] Based on the above, the present invention provides an intelligent urine testing module, control method, and intelligent toilet. Compared with the prior art, it uses a combined design of electrode pads, electrode box assemblies, and a push assembly to replace traditional test strips for urine testing, enabling multi-element detection and a fully automated urine testing process. Simultaneously, by embedding the detection probe group at the front end of the push assembly, the detection circuit of the electrode pads is integrated with the push function into the same module, avoiding the need for additional signal transmission modules (such as wires and interfaces), reducing the overall module size, and making it easier to integrate into the limited space of household appliances such as intelligent toilets and urinals. Furthermore, a ring-shaped seal is used at the detection port to achieve a sealing effect, preventing urine from seeping into and contaminating the internal components and electrode pads of the module, ensuring that the electrode pads inside the module are not cross-contaminated during replacement, improving detection accuracy and extending the module's lifespan.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] In the description of this invention, it should be noted that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more. Additionally, the term "comprising" and any variations thereof mean "at least comprising."

[0020] To address the technical problems of existing urine testing modules built into toilets, such as large size, susceptibility to contamination, and limited test results, or to achieve at least one or more of the aforementioned advantages, an embodiment of the present invention provides an intelligent urine testing module. Please refer to... Figure 1 , Figure 2 The intelligent urine test module includes a housing 10, an electrode box assembly 20, a push assembly 30, a flipping assembly 40, and an annular seal 50.

[0021] The specific structure of the housing 10 should be rationally designed in conjunction with the specific structure and operating principle of the electrode box assembly 20, the pushing assembly 30, and the flipping assembly 40. It should be noted that... Figure 1 The housing 10 shown is only one embodiment. The housing 10 is provided with a detection port 111, and the design position of the detection port 111 should facilitate the flow of urine so that it can be effectively collected at the detection port 111.

[0022] The electrode box assembly 20 is detachably installed on the housing 10. The electrode box assembly 20 has a receiving cavity for accommodating electrode pads S, which are stacked and arranged in a predetermined direction within the receiving cavity. Each electrode pad S integrates a detection circuit for collecting urine information. The detachable electrode box assembly 20 facilitates the addition of new electrode pads S, improving practicality. The detachable connection between the electrode box assembly 20 and the housing 10 includes, but is not limited to, threaded connection, snap-fit ​​connection, magnetic connection, slide rail insertion, and spring clip engagement.

[0023] Please continue reading. Figure 2 , Figure 4The push component 30 is movably mounted on the housing 10. The push component 30 integrates a detection probe group 33, which is embedded in the front end face of the push component 30 and can form an electrical connection with the detection circuit of the electrode plate S through physical contact. By making contact with the detection circuit through the detection probe group 33, the urine information collected by the detection circuit can be received.

[0024] The pushing component 30 pushes the electrode plate S along a preset path to a preset position on the detection port 111, thereby establishing a stable electrical connection between the detection probe group 33 and the detection circuit of the electrode plate S. This allows for the detection of the urine after the electrode plate S completes urine collection. According to the design, the pushing component 30 may include, but is not limited to, linear reciprocating mechanisms such as pneumatic push rod assemblies, electric piston assemblies, lead screw and nut transmission assemblies, pulley transmission assemblies, gear and rack assemblies, and guide rail and slider assemblies to achieve the pushing function of the electrode plate S.

[0025] Furthermore, to effectively protect the internal structure of the module, this embodiment retains the used original electrode plate S at the detection port 111 to seal the detection port 111, thereby preventing liquid from entering the module. Specifically, when urine testing is required, the pushing component 30 pushes the new electrode plate S into the detection port 111 while simultaneously pushing the original electrode plate S located at the detection port 111 away from the detection port 111. This effectively avoids the risk of leakage when changing test strips, which is typically required by existing technologies, and the risk of cross-contamination that may occur when switching between the new and original electrode plates S. In other words, this embodiment utilizes the pushing out of the new electrode plate S to automatically push out the used original electrode plate S, effectively achieving seamless sealing of the detection port 111.

[0026] Preferably, the electrode S located at the detection port 111 is press-fitted with the detection port 111 to effectively prevent urine from entering the interior of the intelligent urine test module through the detection port 111. This avoids urine contamination of internal components and also prevents urine from infecting the unused electrode S inside, thus affecting subsequent test results.

[0027] To further improve the sealing between the detection port 111 and the electrode plate S, please refer to [link / reference needed]. Figure 4 The intelligent urine testing module further includes an annular seal 50, which is disposed on the detection port 111 to achieve a seal between the electrode plate S and the detection port 111, effectively preventing urine from entering the intelligent urine testing module. The surface of the annular seal 50 that contacts the electrode plate S is made of an elastic material, which deforms under pressure to achieve a seal between the detection port 111 and the electrode plate S.

[0028] Further, please refer to Figure 3 , Figure 5 The annular seal 50 has an inner annular cavity 51 into which the electrode sheet S can be embedded. In this embodiment, the cross-sectional area of ​​the inner annular cavity 51 gradually decreases along its axial direction as it approaches the end face away from the push assembly 30. This design of reduced cross-sectional area allows the annular seal 50 to provide a better seal at the detection port 111 compared to a conventional design with a constant cross-sectional area, while also preventing the electrode sheet S embedded in the inner annular cavity 51 from falling out. Furthermore, the annular seal 50 provides deformation buffering, meaning that when replacing the electrode sheet S, the annular seal 50 generates lateral pressure within the inner annular cavity 51, effectively pushing out and discarding the used electrode sheet S.

[0029] Please continue reading. Figure 3 The annular seal 50 is provided with a positioning part 53 in the direction close to the housing 10. The housing 10 is provided with a positioning groove. The positioning part 53 is embedded in the positioning groove to realize the positioning of the annular seal 50 and facilitate installation.

[0030] More preferably, please refer to Figure 4 The intelligent urine testing module also includes a protective cover 60, which is detachably connected to the detection port 111. The detachable connection can be, but is not limited to, threaded connections, snap-fit ​​connections, pin connections, hinge connections, etc.

[0031] Please continue reading. Figure 3 , Figure 5 The protective cover 60 extends from its end face near the push assembly 30 to form a limiting portion 62, and the annular seal 50 extends from its end face near the push assembly 30 to form a limiting groove 52. The limiting portion 62 is embedded in the limiting groove 52 to confine the annular seal 50 between the protective cover 60 and the detection port 111. Through the design of the above-mentioned limiting structure, on the one hand, the positional stability of the annular seal 50 during installation and use can be ensured, preventing displacement or detachment of the annular seal 50 due to the push assembly 30 pushing the electrode plate S, thereby ensuring a good sealing effect; on the other hand, the tight cooperation between the limiting portion 62 and the limiting groove 52 can further enhance the connection reliability between the protective cover 60, the annular seal 50, and the electrode plate S, improving the structural stability of the entire intelligent urine detection module.

[0032] The protective cover 60 has a through groove 61, which exposes the electrode S located at the detection port 111. This through groove 61 allows the electrode S to directly contact the urine, enabling the detection of various components in the urine. The shape and size of the through groove 61 can be designed according to the specific shape and size of the electrode S, ensuring that the electrode S is exposed and not obstructed or interfered with by the protective cover 60. It also prevents urine from entering the protective cover 60 and damaging other components during use.

[0033] Based on the above, the method for implementing intelligent urine testing in this embodiment is as follows: the electrode plate S is pushed to a preset position of the detection port 111 by the pushing component 30, and the original electrode plate S located at the detection port 111 is dislodged; when urine passes through the detection port 111 and splashes onto the surface of the electrode plate S, urine detection can be performed by the detection circuit. When the urine test is completed or not performed, the used original electrode plate S is still locked on the detection port 111, forming an isolation to prevent urine from entering the urine test module and contaminating other electrode plates S inside. When the urine test is completed or when it is necessary to replace the electrode plate S for a new urine test, the pushing component 30 returns to the initial position, the new electrode plate S in the electrode box assembly 20 is placed again on the front end of the pushing component 30, and the pushing component 30 pushes the new electrode plate S to the preset position of the detection port 111 along a preset path, and dislodges the original electrode plate S, thus completing the replacement of the electrode plate S.

[0034] This embodiment uses a combination of electrode pad S, electrode box assembly 20, and push assembly 30 to replace traditional test strips for urine testing. This achieves the requirements of pollution-free, multi-element detection, and a fully automated urine testing process. Simultaneously, the push assembly 30 precisely pushes the electrode pad S to the detection port 111, eliminating the need for manual intervention. This avoids the manual adjustment of immersion depth and angle required with traditional test strips, fundamentally eliminating detection position errors caused by human error (such as missed detection due to shallow immersion or contamination of other components due to excessive immersion). It also avoids the problems of low positioning accuracy and easy deviation from the detection area inherent in traditional test strip sliding structures.

[0035] Meanwhile, by utilizing the design of embedding the detection probe group 33 on the front end of the push assembly 30, the detection circuit of the electrode S is integrated with the push function in the same module through the detection probe group 33. On the one hand, this avoids the need for additional signal transmission modules (such as wires and interfaces), reduces the overall size of the module, and makes it easier to integrate into the limited space of household appliances such as smart toilets and urinals. On the other hand, in traditional urine testing devices, the driving mechanism for transporting urine test strips or electrode S is generally separate from the detection mechanism, which occupies a large space and has a delayed response. In this embodiment, by integrating the detection probe group 33 on the front end of the push assembly 30 and utilizing the conduction between the detection circuit of the electrode S and the detection probe of the push assembly 30, the push assembly 30 and the urine testing part are effectively integrated. This allows the detection signal to act directly on the testing part, effectively shortening the action time, achieving a fast response, reducing transmission parts, lowering the failure rate, and extending the service life.

[0036] Furthermore, the integration of all components within the same housing 10 reduces space requirements. For example, traditional urine testing equipment requires separate test strip compartments, detection chambers, and signal transmission modules, while this module integrates each functional unit into a single component through the integrated design of "housing 10 – electrode box assembly 20 – push assembly 30". This advantage allows the module to be easily integrated into the limited space of household appliances such as smart toilets and urinals (e.g., the side or front area of ​​the toilet), avoiding the limitations of traditional urine testing equipment that requires separate placement due to its large size, and greatly improving the product's suitability for home use and aesthetics.

[0037] Furthermore, this embodiment utilizes the physical electrical connection between the detection probe group 33 on the push component 30 and the detection circuit of the electrode plate S to ensure stable conduction during detection, effectively reducing human error, improving detection accuracy, and realizing a fully automated process for urine testing. That is, compared to traditional test strips that rely on visual interpretation of the colorimetric card or require additional camera equipment to assess the color development, the automatic electrical signal quantification measurement of the electrode plate S avoids interference from subjective factors such as lighting conditions (e.g., unclear color development in low light) and observation experience (novices are prone to misjudging color gradients), thus improving the reliability of the test results. A ring-shaped seal 50 is used at the detection port 111 to achieve a sealing effect, preventing urine from penetrating and contaminating the internal components and electrode plate S of the module, ensuring that the electrode plate S inside the module is not cross-contaminated during replacement, improving detection accuracy and the module's lifespan.

[0038] Preferably, please refer to Figure 1 , Figure 2The housing 10 includes a first channel 11 for placing the push assembly 30 and communicating with the detection port 111, and a second channel 12 for placing the electrode box assembly 20. The push assembly 30 pushes the electrode sheet S along a preset path towards the extension direction of the first channel 11. The electrode sheets S in the electrode box assembly 20 are stacked and arranged along the extension direction of the second channel 12. The extension direction of the first channel 11 intersects the extension direction of the second channel 12. Through the above arrangement, the electrode box assembly 20 and the push assembly 30 are arranged at a certain angle, thereby reducing the length of the entire intelligent urine detection module, making the structure more compact, and effectively applicable to the application of various intelligent toilets / urinals or other devices in limited spaces.

[0039] Preferably, please refer to Figure 6 The electrode box assembly 20 includes a box body 21 and an outer cover 22. The box body 21 and the housing 10 are detachably connected. The electrode sheet S is located inside the box body 21. The outer cover 22 is movably mounted on the box body 21. The box body 21 and the housing 10 can be installed or removed by operating the outer cover 22.

[0040] The box body 21 and the shell 10 can be connected by a snap-fit ​​structure, a threaded structure, a magnetic structure or other detachable connection structure. The shell and the box body 21 are connected by a rotating connection, a sliding connection or a plug-in connection. By opening, closing, rotating or sliding the outer cover 22, the relative displacement between the box body 21 and the shell 10 can be driven, so as to realize the installation or removal of the electrode box assembly 20.

[0041] Please continue reading. Figure 7 , Figure 8 The electrode box assembly 20 further includes a sliding stop 24; the sliding stop 24 is movably disposed in the receiving cavity of the box body 21, and divides the receiving cavity of the box body 21 into a storage cavity 213 and a movable cavity 214; the storage cavity 213 is located on the side of the box body 21 near the opening (i.e., the opening opened near the connection position of the second channel 12 and the first channel 11) for storing the stacked electrode sheets S. The sliding stop 24 is a structure adapted to the receiving cavity of the box body 21, and its edge slides against the inner wall of the box body 21 to ensure that the sliding stop 24 moves along the length direction of the box body 21.

[0042] Please see Figure 7 The housing 21 has a vent 215 communicating with the movable cavity 214. The vent 215 is used to input compressed air into the movable cavity 214. The sliding stop 24 abuts against the stacked electrode plates S under the action of the compressed air in the movable cavity 214. The vent 215 can be connected to an external miniature air pump (not shown in the figure) through an air pipe (not shown in the figure) to input compressed air into the movable cavity 214.

[0043] Specifically, after the first electrode piece S at the opening of the housing 21 is rotated and transferred to the pushing component 30 by the flipping component 40, in order to ensure that subsequent electrode pieces S can continuously and accurately enter the flipping station, the sliding stop 24 in this embodiment is driven by compressed air to move in the direction of the opening of the housing 21. By pushing the stacked electrode pieces S forward as a whole, it fills the empty position of the removed electrode piece S, so that the next electrode piece S automatically abuts against the initial station at the opening, thereby ensuring that the electrode piece S queue is always aligned with the flipping component 40, providing reliable support for the stability of the continuous detection process.

[0044] Preferably, please refer to Figure 8 To achieve a sealing effect within the movable cavity 214 and prevent compressed air leakage, a sealing ring is provided at the contact gap between the sliding stop 24 and the inner cavity of the housing 21. The sealing ring can be fitted into a groove on the outer surface of the sliding stop 24, allowing it to slide with the sliding stop 24 under the action of compressed air and achieve a sealing effect, preventing compressed air leakage within the movable cavity 214 and ensuring pneumatic drive efficiency.

[0045] Based on the above, the driving process for the electrode box assembly 20 to pick up the electrode sheet S using the sliding stop 24 in this embodiment is as follows: Please refer to Figure 7 Initially, the storage cavity 213 is filled with stacked electrode sheets S. The foremost electrode sheet S protrudes from the opening and aligns with the position of the flipping assembly 40, while the sliding stop 24 is located at the rearmost position of the electrode sheet S away from the opening. As the flipping assembly 40 rotates the first electrode sheet S at the opening to the front face of the pushing assembly 30, the control unit triggers a micro air pump to input compressed air into the vent 215. The compressed air enters the movable cavity 214 and pushes the sliding stop 24 towards the opening, thus pushing all the stacked electrode sheets S in the storage cavity 213 forward until the next electrode sheet S reaches the initial position of the opening. When the electrode sheets S in the electrode box assembly 20 are exhausted, the control unit shuts off the micro air pump, releasing the air pressure in the movable cavity 214. The user can then manually remove the electrode box assembly 20 and fill the box 21 with new electrode sheets S.

[0046] This embodiment achieves automatic replacement of the electrode pad S through the coordinated design of the sliding stop 24 and compressed air, ensuring the stability of the electrode pad S supply during continuous testing and significantly improving the automation level and user experience of the urine test module. Of course, those skilled in the art can also replace the coordinated design of the sliding stop 24 and compressed air with other designs, such as the coordinated design of the sliding stop 24 and a spring component, to achieve automatic replacement of the electrode pad S, all of which fall within the protection scope of this invention.

[0047] In an alternative implementation, please refer to Figure 9The pushing component 30 includes a pushing slider 31 and a first driving component 32; the pushing slider 31 is movably disposed within the housing 10, and the first driving component 32 drives the pushing slider 31 to reciprocate along a preset path to push the electrode sheet S in the electrode box assembly 20 to the preset position of the detection port 111.

[0048] For specific implementation details, please refer to [link / reference]. Figure 2 The pusher component 31 includes a slider body 311, a detection circuit board 312, and a stylus fixing block 313. The detection stylus group 33 is integrated on the detection circuit board 312. The detection stylus group 33 includes a plurality of arrayed elastic stylus members for elastic contact with the electrode plate S, ensuring the stability and reliability of the electrical connection between the detection stylus group 33 and the electrode plate S, and avoiding poor electrical contact. The stylus fixing block 313 is connected to one end of the slider body 311 near the detection port 111. The detection circuit board 312 is fixed between the slider body 311 and the stylus fixing block 313, and the detection stylus group 33 on the detection circuit board 312 passes through the stylus fixing block 313 and is exposed on the front end face of the pusher component 30 for contacting the electrode plate S. When the electrode plate S is located on the pusher component 30, the detection circuit of the electrode plate S makes contact and conducts with the detection stylus group 33 on the pusher component 30. The detection circuit board 312 is used to communicate with the main control board to transmit relevant instructions for urine testing and data information collected or analyzed.

Figure 9 In this embodiment, the push slider 31 preferably also includes a sensor element 314 for detecting whether the electrode plate S is in position on the push assembly 30. The sensor element 314 includes, but is not limited to, a proximity sensor, a photoelectric sensor, a Hall sensor, a pressure sensor, etc.

[0050] Preferably, the slider body 311 has an internal cavity that facilitates the detection of the circuit leads of the circuit board 312. At least one sealing ring groove is also formed on the surface of the slider body 311. The push assembly 30 further includes a slider sealing ring 34, which is nested within the sealing ring groove and forms a seal with the housing 10, effectively sealing and protecting the detection circuit board 312 and the detection pin assembly 33 in the push rod assembly.

[0051] It should be noted that the specific structure of the stylus fixing block 313 can be reasonably designed based on the structure of the detection circuit board 312 and related electronic components. Similarly, the specific structure of the slider body 311 can be reasonably designed based on the actual connection relationship of each component. Based on the concept of this invention, its structural deformation and improvement fall within the protection scope of this invention.

[0052] The first driving component 32 includes, but is not limited to, a motor-driven lead screw and nut structure, a motor-driven rack and pinion mechanism, a motor-driven crank-slider structure, a linear module structure, a direct-acting cylinder structure, a hydraulic rod drive structure, or an electromagnetic drive structure. This embodiment preferably uses a motor-driven lead screw and nut structure; please refer to [link / reference]. Figure 3 The first driving component 32 includes a first motor 321, a lead screw 322, and a nut 323. The nut 323 is connected to the end of the slider body 311 away from the detection port 111. The lead screw 322 passes through the nut 323 and is threadedly connected to the nut 323 and extends into the inner cavity of the slider body 311. The first motor 321 drives the lead screw 322 to rotate, thereby causing the nut 323 to move on the lead screw 322, which in turn drives the slider 31 to reciprocate within the housing 10 toward the detection port 111, specifically within the first channel 11.

[0053] In another alternative implementation, please refer to Figure 2 , Figure 4 A flipping component 40 is disposed between the electrode box assembly 20 and the pushing component 30, and is used to flip the electrode sheet S in the electrode box assembly 20 onto the pushing component 30, so that the detection circuit contacts the detection probe group 33. The flipping component 40 can be configured with multiple mechanisms to sequentially flip the electrode sheet S stacked in the electrode box assembly 20 onto the pushing component 30 one by one, such as a worm gear structure, a multi-link structure, or a cam structure. In this embodiment, the flipping component 40 is located at the connection position between the first channel 11 and the second channel 12, facilitating the flipping of the electrode sheet S in the electrode box assembly 20 onto the pushing component 30. By designing the flipping component 40 to transfer the electrode sheet S, not only can miniaturization be better achieved, but the problem of mechanism jamming or wear caused by a single pushing drive method can also be effectively avoided. That is, this embodiment uses the flipping component 40 to separate mechanical stress and prevent the electrode sheet S from getting stuck in the gap.

[0054] Please see Figure 4 , Figure 10 The flipping component 40 includes a first claw 41, a second claw 42, a second drive member 43, and a third drive member 44. The first claw 41 and the second claw 42 are positioned opposite each other and spaced apart between the electrode box assembly 20 and the push assembly 30. The second drive member 43 drives the first claw 41 and the second claw 42 to move closer or further apart to engage or disengage the electrode sheet S. The third drive member 44 drives the first claw 41 and the second claw 42 to rotate by a preset angle to flip the electrode sheet S in the electrode box assembly 20 onto the push assembly 30.

[0055] In specific implementation, the second driving component 43 can adopt a bidirectional driving device, such as a pneumatic push rod, a micro electric push rod, or a structure of screw drive combined with a motor, or a structure of guide rail slider drive combined with a motor, so as to effectively realize the relative approach and distance between the first claw 41 and the second claw 42.

[0056] Preferably, the second driving member 43 includes a second motor 431, a bidirectional lead screw 432, and a threaded slider 433. The second motor 431 is drivenly connected to the bidirectional lead screw 432. Each of the opposite ends of the bidirectional lead screw 432 is threadedly connected to a threaded slider 433, and the two threaded sliders 433 enable the second driving member 43 to move the first jaw 41 and the second jaw 42 closer or further apart via the bidirectional lead screw 432 and the threaded sliders 433. The opposite ends of the bidirectional lead screw 432 have threads with different directions of rotation, and each of the opposite ends of the bidirectional lead screw 432 is threadedly connected to a threaded slider 433. The two threaded sliders 433 can be directly or indirectly hinged to the first jaw 41 and the second jaw 42, respectively. The second motor 431 drives the bidirectional lead screw 432 to rotate, thereby causing the threaded sliders to move closer or further apart, and in turn, causing the first jaw 41 and the second jaw 42 to move closer or further apart, thus releasing the electrode plate S located at the end of the electrode box assembly 20 or the electrode plate S located on the push assembly 30. In this embodiment, the first claw 41 and the second claw 42 are preferably provided with guide slopes that contact the electrode plate S. The guide slopes can effectively guide the electrode plate S to automatically center and prevent it from slipping off during the flipping process.

[0057] Please continue reading. Figure 4 , Figure 8 The flipping assembly 40 further includes a first transmission chuck 45 connected to the first jaw 41 and a second transmission chuck 46 connected to the second jaw 42. The second driving member 43 is connected to the first transmission chuck 45 and the second transmission chuck 46 in a transmission connection to drive the first transmission chuck 45 and the second transmission chuck 46 to move closer or further away from each other.

[0058] The second driving component 43 includes a second motor 431, a bidirectional lead screw 432, and a threaded slider 433. The second motor 431 is connected to the bidirectional lead screw 432. Each of the two opposite ends of the bidirectional lead screw 432 is threadedly connected to a threaded slider 433, and the two threaded sliders 433 are respectively hinged to the first transmission chuck 45 and the second transmission chuck 46. The first transmission chuck 45 has a first driven tooth 451, the second transmission chuck 46 has a second driven tooth 461, and the third driving member 44 includes a third motor 441, a first driving tooth 442, and a second driving tooth 443. The first driving tooth 442 meshes with the first driven tooth 451, and the second driving tooth 443 meshes with the second driven tooth 461. The third motor 441 drives the first driving tooth 442 and the second driving tooth 443 to rotate so as to simultaneously drive the first driven tooth 451 and the second driven tooth 461 to rotate, thereby driving the first jaw 41 on the first transmission chuck 45 and the second jaw 42 on the second transmission chuck 46 to rotate synchronously.

[0059] Preferably, the width of the first driving tooth 442 is greater than the width of the first driven tooth 451, and the width of the second driving tooth 443 is greater than the width of the second driven tooth 461, so as to ensure that the driven teeth can move relative to each other and rotate synchronously.

[0060] In this embodiment, please refer to Figure 10 The first transmission chuck 45 and the second transmission chuck 46 are hinged to their corresponding threaded sliders 433 and connected to the third drive component 44 via gear meshing. This allows the jaws to move closer or further apart and rotate without interfering with each other. Its structure is simple, low-cost, and eliminates the need for more complex structures to prevent interference, further saving space.

[0061] Of course, other transmission schemes can also be adopted, as long as they can achieve relative movement and synchronous rotation between the first chuck 41 and the second chuck 42. This case does not impose any restrictions on this.

[0062] Furthermore, the first transmission chuck 45 and the second transmission chuck 46 are respectively provided with arc-shaped grooves that do not interfere with the rotation of the first transmission chuck 45 and the second transmission chuck 46. The bidirectional lead screw 432 passes through the arc-shaped grooves and is connected to the first transmission chuck 45 and the second transmission chuck 46 through a hinge, thereby further saving space and achieving a compact structure.

[0063] Furthermore, the stable electrical connection between the detection circuit and the detection probe group 33 provides a reliable channel for data transmission. The urine information collected by the electrode S can be transmitted in real time to the main control module of the relevant device (such as an integrated display screen or Wi-Fi module) and synchronized to the user's mobile phone or medical platform. This feature is particularly crucial in emergency scenarios (such as when an elderly person living alone suddenly develops diabetes and needs to monitor urine glucose): the test results can be pushed to the terminal of family members or doctors immediately, buying time for rapid intervention and treatment; in daily health management, trend analysis (such as the urine protein content change curve) can also be generated through long-term data accumulation to assist in early disease warning.

[0064] This embodiment uses electrode pads S instead of traditional test strips for urine testing. This solution can simultaneously detect multiple biochemical indicators in urine (such as pH, glucose, conductivity, etc.), avoiding the limitations of single-indicator detection. Compared to existing technologies that rely on multi-step manual operation, this design automates the entire urine testing process, fundamentally solving the problems of cumbersome procedures, high error rates, and low detection efficiency caused by manual intervention in traditional methods, thereby improving the accuracy and efficiency of test results. In addition, the single-use mechanism of electrode pads S eliminates the need for auxiliary modules such as cleaning and drying required by traditional test strips, effectively reducing the size of the device and making it more suitable for home medical scenarios. It not only meets the convenient use needs of elderly users or in emergency situations, but also significantly optimizes the user experience through its plug-and-play and automatic electrode pad replacement features. Its modular design and maintenance-free characteristics meet the trend of "seamless interaction" in smart homes.

[0065] Example 2 Embodiment 2 of the present invention also provides a control method for an intelligent urine testing module, which employs the intelligent urine testing module described in Embodiment 1 above. The specific structure, function, and role of the intelligent urine testing module can be referred to in Embodiment 1 above, and will not be repeated here.

[0066] The control method includes the following steps: When a urine test command is received, the pushing component 30 pushes the electrode S in the electrode box component 20 to the preset position of the detection port 111 along a preset path. At the same time as pushing the new electrode S into the detection port 111, the original electrode S located in the detection port 111 is pushed out in a direction away from the detection port 111, so that the new electrode S is sealed by the annular seal 50. After the new electrode S completes urine collection, the urine is detected by the detection circuit and the detection probe group 33.

[0067] For specific implementation details, please refer to [link / reference]. Figure 11When a urine test command is received, it can be triggered in various ways, such as by the user clicking the urine test start button on the accompanying smart terminal, or by a device associated with the smart urine test module (such as a smart toilet that detects someone using the device and meets certain conditions) sending a corresponding signal to the control unit of the smart urine test module. At this time, the push component 30 starts working, pushing the unused new electrode piece S from its initial position to a preset position. Simultaneously, after the push component 30 reaches the preset position, the unused new electrode piece S on its front end will automatically push over the used original electrode piece S located at the detection port 111.

[0068] When urine passes over a new, unused electrode plate S, the detection circuit and the detection probe assembly 33 work together to perform urine detection. The detection circuit integrates various sensors, such as an electrochemical sensor to detect the concentration of specific chemical components in the urine and a pH sensor to measure the urine's pH value. When urine comes into contact with the electrode plate S, various components in the urine react electrochemically with the sensors, generating corresponding changes in electrical signals. The detection probe assembly 33 transmits these electrical signals to the signal processing unit of the intelligent urine detection module. The signal processing unit amplifies and filters the electrical signals before converting them into corresponding urine component data, such as glucose content and protein content, using a built-in algorithm. After completing the urine test or when a new test is needed, the push assembly 30 returns from a preset position to its initial position. During the return process, the position of the push assembly 30 can be monitored in real time by the control unit. Signals from position sensors (such as photoelectric sensors) are used to precisely control the motor's stop position, ensuring that the push assembly 30 accurately returns to its initial position, preparing for the next test.

[0069] After the push component 30 returns to its initial position, the flip component 40 drives the unused new electrode piece S in the electrode box assembly 20 to flip onto the push component 30, ready for the next detection. During the flipping process, the electrode box assembly 20 must be designed to ensure the stable placement of the electrode piece S, for example, by using an electrode piece S slot with a flexible snap-fit ​​to ensure that the electrode piece S does not shift or fall off during the flipping process. Simultaneously, to achieve accurate replenishment of the electrode piece S, positioning sensors (such as infrared photocell sensors) can be installed on the electrode box assembly 20 and the push component 30. When the electrode box assembly 20 flips to the appropriate position, the positioning sensor detects a signal, and the control unit controls the motor to stop rotating. At this time, the unused new electrode piece S in the electrode box assembly 20 is precisely aligned with the front end face of the push component 30, and the detection circuit of the new electrode piece S makes physical electrical contact with the detection probe group 33. Furthermore, in order to better connect the detection circuit on the electrode plate S with the detection stylus group 33 on the push assembly 30, the push assembly 30 can also transfer the electrode plate S onto itself through a simple translation or adsorption action (such as using an electromagnet to adsorb the electrode plate S), thus completing the replenishment process of the electrode plate S.

[0070] The intelligent urine testing module control method in this embodiment, through the coordinated work of various components, eliminates the need for human intervention. It automates the entire process of electrode pad S pushing and replacement, urine testing, and data transmission simply by following instructions through the control unit. This reduces the error rate of manual operation, improves the convenience of interaction, and effectively enhances testing efficiency and accuracy, providing users with a convenient urine testing experience. It is especially suitable for elderly users with limited mobility or sick patients.

[0071] Example 3 Embodiment 3 of the present invention also provides a urinal (not shown in the figure), which adopts the intelligent urine detection module as described in any of the embodiments of Embodiment 1 above.

[0072] In practice, the intelligent urine test module is installed in the urinal. Preferably, the replacement window of the electrode box assembly 20 is located on the side or top of the urinal, and the detection port 111 is located on the inner wall of the urinal.

[0073] The urinal using the intelligent urine testing module provided in this embodiment of the invention can automatically perform urine testing, which not only avoids the limitations of traditional test strip testing with single indicator detection, but also improves the accuracy and efficiency of the test results.

[0074] It should be noted that the specific structure, function and role of the intelligent urine test module can be referred to the aforementioned Embodiment 1, and the specific structure, function and role of the intelligent urine test method can be referred to the aforementioned Embodiment 2, and will not be repeated here.

[0075] Example 4 The present invention also provides an intelligent toilet, wherein the intelligent toilet employs an intelligent urine detection module as described in any embodiment of the first embodiment above or an intelligent urine detection method as described in any embodiment of the second embodiment above.

[0076] In specific implementation, such as Figure 12 As shown, the intelligent urine detection module is located at the front end of the intelligent toilet, and the detection port 111 is located inside the intelligent toilet, making it convenient for users to replace the electrode box assembly 20 without having to go around to the rear end of the toilet for replacement, thus facilitating use. Simultaneously, when the electrode plate S is located at the detection port 111, the electrode plate S and the inner wall surface of the intelligent toilet are a continuous plane.

[0077] Preferably, when the intelligent urine detection module is installed on the front end of the inner wall of the intelligent toilet, the extension direction of the second channel 12 is horizontal, and the extension direction of the first channel 11 is inclined at a preset angle to the extension direction of the second channel 12. The preset angle is between 30° and 90°, and the specific value should be reasonably selected according to the actual inner wall position and internal curvature of the intelligent toilet.

[0078] It should be noted that the specific structure, function and role of the intelligent urine test module can be referred to the aforementioned Embodiment 1, and the specific structure, function and role of the intelligent urine test method can be referred to the aforementioned Embodiment 2, and will not be repeated here.
