Description

Technical Field

[0001] The utility model relates to the technical field of sanitary ware equipment, in particular to a urine detection mechanism of a urinal with urine collection, detection and cleaning functions. Background Art

[0002] Currently, physical examinations basically require going to the hospital for a physical examination. Urine testing, as a basic physical examination item, is very important in outpatient emergency departments, but it is not often taken seriously in family life. Most people have a full physical examination once a year, and some people rarely have a physical examination for several years. As a result, when they get sick, they get a serious illness. Regular physical examinations, especially regular urine testing, are very necessary.

[0003] Urine testing is an important method for diagnosing the physical condition of the human body. It can usually detect pH, protein, occult blood, specific gravity, glucose, ketone bodies, urobilinogen, nitrates, white blood cells, bilirubin and vitamin C, etc., reflecting a series of indicators of the body. Urine testing is usually carried out in hospitals. Due to the shortage of medical resources, the examinees often have to queue up for registration, payment, urine collection and other procedures after arriving at the hospital. They also need to wait for batches of urine tests and then queue up to get the results. The operation is cumbersome and wastes a lot of time.

[0004] Chinese patent CN110185115A discloses a urinal with urine detection function, including a urinal body; a urine sample collecting device, which is arranged on the urinal body and used to collect urine samples in the urinal body; a urine sample detection device, used to detect urine samples; a urine sample collecting device, used to collect urine samples in the urine sample collecting device, and send the collected urine samples to the urine sample detection device for detection; a cleaning device, used to clean the urine sample collecting device and the urine sample collecting device; a control device, used to receive instructions to be detected, control the urine sample detection device, the urine sample collecting device, the cleaning device to operate, receive detection data, analyze detection results and send detection results to the customer's mobile phone terminal. The effect of users being able to conveniently understand their own health conditions through urine sample detection is achieved.

[0005] However, in the above scheme, the dropper and the image acquisition device mentioned usually need to move according to the test paper 54 to complete the collection and analysis of urine, which requires that the urine collection pipeline connected to the dropper must also be able to move accordingly. Therefore, a set of motion mechanisms must be designed to drive these components, which not only makes the overall structure complicated and increases the manufacturing cost, but also needs to solve the problem of pipeline entanglement during the movement to avoid damage. In addition, this design also takes up a lot of space, affecting the compactness and aesthetics of the device. Utility Model Content

[0041] Example 1: Reference Figure 1-Figure 3 The utility model proposes a technical solution of a urinal with urine collection, detection and cleaning functions, comprising: a urinal body 1, wherein the urinal body 1 is provided with at least one urine collecting cavity 2 for collecting urine of a user, the bottom of which is connected with a urine conveying module 3 arranged inside the urinal body 1 through a pipeline (such as a U-shaped downpipe), and further comprises a test paper storage module 9 arranged side by side with the urine conveying module 3 along the width direction of the urinal body 1, and a urine detection mechanism 4 arranged on a side of the test paper storage module 9 close to the urine conveying module 3.

[0042] In some embodiments, see Figure 2 The urine detection mechanism 4 includes: a urine collection bracket 5, a test paper pushing module 7, and a urine detection module 8, wherein the urine collection bracket 5 is fixedly arranged below the test paper storage module 9, and can partially extend axially to below the urine delivery module 3; the test paper pushing module 7 is axially installed above the urine collection bracket 5; the urine detection module 8 is fixedly arranged on a side of the test paper storage module 9 close to the urine delivery module 3, and is used to drop the urine to be tested onto the test paper 54 in the test paper pushing module 7.

[0043] In some embodiments, the urinal further includes a push plate mechanism 6, which is disposed on an end of the urine collection bracket 5 away from the test paper storage module 9, and is used to push the test paper 54 soaked with urine to the next processing stage, for example, to the test paper recovery box 55 below.

[0044] Specifically, the urine detection module 8 includes: a mounting bracket 10, a dropper 11 and a color identifier 12, wherein the mounting bracket 10 is fixedly arranged on the outside of the test paper pushing module 7, and an extension plate 13 which can partially extend radially to the top of the test paper pushing module 7 is arranged above the mounting bracket 10; one end of the dropper 11 is connected to the urine delivery module 3, and the other end can be partially inserted into the positioning hole opened in the middle of the extension plate 13, which is the urine drop processing position; the color identifier 12 is fixedly arranged on the outside of the test paper pushing module 7, and is located between the test paper storage module 9 and the dropper 11, and is used to analyze and identify the color change of urine on the test paper 54 after reaction.

[0045] In some embodiments, the test paper pushing module 7 includes: a test paper conveying unit and a test paper pushing unit, wherein the test paper pushing unit includes: a test paper holder 26, one side of which has an outward expansion plate 18 extending in a direction perpendicular to its axial direction; the test paper conveying unit includes: a horizontal slide rail 14, a transmission belt 15, and a drive motor 17, wherein the drive motor 17 is fixedly arranged on the urine collection holder 5, and is installed opposite to the mounting holder 10 in the urine detection module 8 (that is, the two are respectively located on the inner and outer sides of the horizontal slide rail); the transmission belt 15 is connected to the drive motor 17 through a pulley; the horizontal slide rail 14 is fixedly arranged on the urine collection holder 5, and is located between the urine detection module 8 and the transmission belt 15; specifically, the outward expansion plate 18 is meshed with the inner rack of the transmission belt 15, so that the outward expansion plate 18 can reciprocate on the horizontal slide rail 14, thereby driving the test paper holder 26 to reciprocate along the long axis direction of the horizontal slide rail 14, and the test paper holder 26 is provided with a positioning ear plate 29 extending axially for carrying the test paper 54.

[0046] Preferably, a horizontal sliding block 16 is integrally provided at the bottom of the outer expansion plate 18 and is axially mounted on the horizontal sliding rail 14 .

[0047] In some embodiments, the connection between the urine transport module 3 and the urine collecting chamber 2, and the connection between the pulley and the transmission belt 15 are both prior arts for those skilled in the art, and are not described in detail herein and are not shown in the drawings.

[0048] Chinese patent CN110185115A discloses a urinal with urine detection function, wherein the dropper and image acquisition device usually need to move according to the test paper to complete urine collection and analysis, which requires that the urine collection pipeline connected to the dropper must also be able to move accordingly. Therefore, a set of motion mechanisms must be designed to drive these components, which not only makes the overall structure complicated and increases the manufacturing cost, but also needs to solve the problem of pipeline entanglement during the movement to avoid damage. In addition, this design also takes up a lot of space, affecting the compactness and aesthetics of the device.

[0049] In contrast, the technical solution in this embodiment adopts a fixed setting mode, that is, the dropper 11 and the color identifier 12 are fixedly installed, and there is no need to design separate moving mechanisms for the dropper 11 and the color identifier. This design simplifies the structure, so that the pipes connected thereto are also simplified, because there is no need to move them, which saves space and reduces possible failures and maintenance requirements. Since there is no need for a complex moving mechanism and additional space for movement, the device can be designed to be thinner and lighter, which helps to achieve the thinning and lightweight of the urinal, while reducing production costs and improving the stability and reliability of the device.

[0050] The solution mentioned in this embodiment can allow urine to naturally flow into the urine collecting chamber 2 and enter the urine transport module 3 through the U-shaped drain pipe while the user is using the urinal. Urine collection can be completed without additional operation, and the automatic detection and recovery of urine can be achieved through the coordinated use of the test paper pushing module 7 and the pushing plate mechanism 6.

[0051] Specifically, when the user uses the urinal, urine flows into the urine collecting cavity 2 and finally enters the urine transport module 3. At the same time, the test paper storage module 9 provides unused test paper 54, and the test paper pushing module 7 axially translates the test paper 54 to one end of the horizontal slide rail 14 close to the push plate mechanism 6. When the test paper 54 axially translates to the position of the urine detection module 8, the dropper 11 drops the urine to be tested in the urine transport module 3 onto the test paper 54 located in the test paper pushing module 7.

[0052] In the above-mentioned prior art, the test paper 54 soaked in urine needs to be retained for a period of time to allow the substances in the urine to react with the chemicals on the test paper 54, resulting in a color change. Finally, the color identifier 12 is moved to the position of the test paper 54, and the image of the test paper 54 is automatically captured. The captured image is processed by a built-in algorithm (existing technology, which will not be repeated here), and the color change on the test paper 54 is compared with the preset standard color card to determine whether there are specific chemical components or biomarkers in the urine based on the color difference.

[0053] In this embodiment, the image capture and processing process of the test paper 54 is further optimized to improve efficiency and accuracy. The main reason is that after the test paper 54 is axially translated to the position of the urine detection module 8, the color identifier 12 does not need to physically move to the position of the test paper 54, but captures the image of the test paper 54 by reducing its movement speed (of course, it can also stay at an appropriate position in extreme cases), thereby reducing the number of mechanical moving parts inside the urinal body 1, improving the stability and reliability of the device, and accurately calculating the time required for the chemical substances on the test paper 54 to react with the substances in the urine through a pre-set program. During the time, the test paper push module 7 reduces the movement speed or stops moving to ensure sufficient reaction time. At the same time, the color recognizer 12 continuously monitors the color change of the test paper 54. Once the preset reaction time is reached, the image of the test paper 54 is automatically captured immediately. Then, the image of the test paper 54 is analyzed by the built-in image processing algorithm of the color recognizer 12 (this is the prior art and will not be repeated here), and the color change is compared with the standard color card. After the test is completed, the push plate mechanism 6 pushes the used test paper 54 to the waste collection area, and the new test paper 54 is supplied from the test paper storage module 9 to the test paper push module 7 to prepare for the next test. At the same time, the spatial layout is optimized, making the entire urinal design more compact and beautiful, and also simplifying the subsequent cleaning and maintenance work, which helps to maintain the performance and sanitary condition of the equipment for a long time, and further reduces the demand for moving parts and complex mechanisms inside the urinal body 1.

[0054] In summary, this embodiment not only realizes automated urine testing, but also optimizes the design of the test by using a fixed image capture device and a dropper, thereby improving the convenience of operation, the efficiency of testing, and the stability of the equipment.

[0055] Embodiment 2: Reference Figure 3 The utility model proposes a technical solution of a urinal with urine collection, detection and cleaning functions, which includes the various components in the above embodiments. Further, the urine delivery module 3 of the urinal in this embodiment includes: a first peristaltic pump 19, a second peristaltic pump 20, a cleaning liquid delivery pipe 21, a mixing delivery pipe 22 and a urine delivery pipe 23;

[0056] Among them, the first peristaltic pump 19 is connected to the U-shaped drain pipe through a separation structure, which is used to separate urine and clean water into different delivery pipes. The second peristaltic pump 20 is fixedly arranged below the first peristaltic pump 19. One end of the cleaning liquid delivery pipe 21 is connected to the external cleaning liquid storage tank, and the other end of the cleaning liquid delivery pipe 21 is connected to the first end of the second peristaltic pump 20. The mixing delivery pipe 22 has at least one three-way connector 24, and the first end of the three-way connector 24 is connected to the second end of the second peristaltic pump 20, the second end of the three-way connector 24 is connected to the first end of the first peristaltic pump 19, and the third end of the three-way connector 24 is connected to the external drain port. One end of the urine delivery pipe 23 is connected to the second end of the first peristaltic pump 19, and the other end of the urine delivery pipe 23 is connected to the urine detection mechanism 4.

[0057] For example, the separation structure is composed of at least one urine delivery pipe 23 with a one-way valve and a clean water delivery pipe with a one-way valve. The urine delivery pipe 23 and the clean water delivery pipe are respectively connected to the U-shaped drain pipe, that is, the inlet of the U-shaped drain pipe is connected to the output port in the urine collecting cavity, and the two output ports are respectively connected to the urine delivery pipe and the clean water delivery pipe.

[0058] The connection between the separation structure and the first peristaltic pump 19 is known to those skilled in the art and is not described in detail herein and is not shown in the drawings.

[0059] Chinese patent CN219089369U discloses a urine sampling device and a detection system, wherein the urine and clean water need to be transported using two different pumps respectively.

[0060] In this embodiment, the additional driving mechanism is removed through an improved design, and only a single first peristaltic pump 19 is used, which is connected to the urine delivery pipe 23 and the clean water delivery pipe at the same time, and a control system is used to realize the control of two different fluids by a single peristaltic pump, wherein the control system can be based on a timer, a sensor or a more complex intelligent control algorithm to ensure that the urine is delivered to the detection mechanism at the appropriate time and the cleaning fluid is delivered to the urinal at the same time, and although the urine delivery pipe 23 and the clean water delivery pipe are connected to the same pump body, they are still separated in physical layout, and each is equipped with a one-way valve to prevent cross-contamination of fluids.

[0061] In addition, a second peristaltic pump 20 can be added to control the delivery of the cleaning liquid. The flow rate and pressure of the cleaning liquid can be independently adjusted without affecting the collection of urine samples, thereby improving the cleaning efficiency of the urinal. It can also work in conjunction with the first peristaltic pump 19 to provide more precise fluid control. For example, when the concentration of the cleaning liquid needs to be fine-tuned or different pressures are required during the cleaning process, the two pumps can be adjusted separately to meet different needs.

[0062] At the same time, through the separation structure connected to the U-shaped drain pipe, urine can be effectively separated from clean water, ensuring that the collected urine is pure and not contaminated by external water, so as to improve the accuracy and reliability of urine samples, and provide a good basis for subsequent detection. The first peristaltic pump 19 and the second peristaltic pump 20 are used to realize the automatic delivery of urine and cleaning liquid without manual intervention, thereby reducing the complexity of operation and the possibility of human error.

[0063] On the other hand, the use of a separate structure and independent delivery pipelines makes the maintenance of the entire system simple and convenient. Each part can be accessed and replaced separately, greatly reducing maintenance costs and time, and through the design of the three-way connector 24, the used cleaning liquid and possible pollutants can be directly discharged to the external drain to avoid environmental pollution.

[0064] In summary, this embodiment significantly improves the functionality and user experience of the urinal through efficient urine collection and separation, automated control, precise fluid control, simple maintenance, resource conservation and environmentally friendly design, modular design and high safety, while providing a reliable sample source for urine testing.

Furthermore, the test paper pushing module 7 of the urinal in this embodiment includes: a test paper pushing unit and a test paper conveying unit for pushing the test paper 54 from the test paper storage module 9 to the bottom of the urine detection module 8.

The test paper holder 26 is slidably connected to the horizontal slide rail 14 through a horizontal slider 16, and has positioning ear plates 29 axially extending at both ends thereof. The positioning ear plates 29 can partially extend into the discharge port at the bottom of the test paper storage module 9 to locate the unloading position of the test paper 54. Furthermore, a test paper side baffle 27 is also provided at the discharge port at the bottom of the test paper storage module 9. The test paper side baffle 27 adopts an L-shaped structure. When the test paper pushing unit is located at the discharge port at the bottom of the test paper storage module, the test paper side baffle 27 is located on both sides of the positioning ear plate 29; and the test paper rear baffle 28 is provided on one side of the test paper holder 26 and is located between the positioning ear plate 29 and the test paper side baffle 27.

[0068] In this embodiment, a discharge port is provided at the bottom of the test paper storage area, and a sunken L-shaped structure is provided at the discharge port to support the stacked test papers. Figure 4 , so as to form an L-shaped discharge port for discharging a test paper (that is, the height of the L-shaped structure is slightly greater than the height of a test paper), so there is no need to open a discharge port on the side wall of the test paper storage area; at the same time, a test paper holder is provided to carry the test paper at the bottom and drive it to move out of the discharge port, thereby realizing automatic discharge, that is, there is no need to set up a separate unloading mechanism in the test paper box.

[0069] This embodiment can ensure the position accuracy of the test paper 54 during the transportation process by partially extending the positioning ear plate 29 into the bottom discharge port of the test paper storage module 9, and ensure that the test paper 54 will not shift during the transportation process, thereby ensuring that the test paper 54 can accurately enter the next step of the detection process. At the same time, the test paper holder 26 provides stable support for it to prevent the test paper 54 from bending or damage during the transportation process, thereby ensuring the integrity of the test paper 54 and the accuracy of the detection.

[0070] Furthermore, through the design of the test paper side baffle 27 and the test paper rear baffle 28, combined with the test paper bracket 26, a receiving cavity for accommodating the test paper can be formed below the test paper storage area to carry the test papers 54 output one by one from the test paper storage module 9, and then the test paper 54 pushing process is realized under the action of the test paper conveying unit, thereby improving the detection efficiency. Preferably, the test paper rear baffle 28 is designed with a certain curvature, so that when the test paper pushing unit moves back to the discharge port below the test paper storage area under the drive of the test paper conveying unit, the curvature setting of the test paper rear baffle 28 can lift and guide the test paper at the bottom of the test paper storage area into the receiving cavity formed by the test paper side baffle 27, the test paper rear baffle 28 and the positioning ear plate 29; and when the test paper pushing unit is to push out the test paper, the rear baffle 28 can also limit the test paper in the receiving cavity.

[0071] On the other hand, the integrated test paper holder 26 and the external expansion plate 18 design help to reduce the volume of the entire test paper pushing module 7, making the device more space-saving and easy to install and maintain.

[0072] In summary, the test paper pushing module 7 described in this embodiment significantly improves the automation level of urine testing and the convenience of operation through technical effects such as precise test paper 54 positioning and transportation, stable test paper 54 support, continuous operation process, compact structural design, modular design, easy maintenance and improved detection efficiency.

[0073] Embodiment 4: Reference Figure 6The utility model proposes a technical solution of a urinal with urine collection, detection and cleaning functions, which includes the various components of the above-mentioned embodiment. Furthermore, the urinal of this embodiment also includes: a push plate mechanism 6, specifically, it includes: a spring 30 (i.e., an elastic reset member), a spring fixing column 31, a pressure plate 32, a rotating shaft 33, a push plate 34, a baffle 35 and a positioning mounting seat 36. The positioning mounting seat 36 is fixedly arranged in the urine collection bracket 5 at one end away from the test paper storage module 9 and is located between the test paper conveying box 25 and the driving motor 17, and a mounting plate is arranged above the positioning mounting seat 36. The push plate 34 is rotatably mounted on one side of the mounting plate via a rotating shaft 33, the baffle plate 35 is fixedly mounted on the other side of the mounting plate, one side of the pressure plate 32 is fixedly mounted above the baffle plate 35, and the other side of the pressure plate 32 is fixedly mounted above the push plate 34 via a rotating shaft 33, and there are at least two spring fixing columns 31, which are respectively fixedly mounted on both sides of the positioning mounting seat 36 and partially extend to above the push plate 34 and the baffle plate 35, and the spring 30 (i.e., the elastic return member) is fixedly mounted between the two spring fixing columns 31, so that the push plate 34 can return to its original position after completing the pushing task.

[0074] In this embodiment, the combination of the spring 30 (i.e., the elastic reset member) and the two spring fixing columns 31 can provide the necessary elastic force drive for the movement of the push plate 34, and by rotating the push plate 34 installed on one side of the mounting plate, the push plate 34 can move smoothly when pushing the test paper 54, and the friction is reduced, thereby improving the durability and reliability of the mechanism. At the same time, by means of the baffle 35 arranged side by side with the push plate 34, it is ensured that the push plate 34 will not deviate from the predetermined track when pushing the test paper 54, thereby ensuring the accuracy of the test paper 54 transportation.

[0075] On the other hand, the elastic force of the spring 30 (i.e., the elastic reset member) can be evenly transmitted to the push plate 34 through the pressure plate 32 that can simultaneously limit the position of the push plate 34 and the baffle plate, thereby ensuring that the push force of the push plate 34 on the test paper 54 is uniform.

[0076] In summary, the push plate mechanism 6 described in this embodiment realizes efficient and accurate pushing of the test paper 54 through the elastic force of the spring 30 (i.e., the elastic reset member), the rotational installation of the push plate 34, the positioning effect of the baffle 35, the pressure transmission of the pressure plate 32, the stability of the positioning mounting seat 36, and the design that is easy to maintain and adjust, thereby improving the automation level of the urine testing process and enhancing the reliability of the system and the user experience.

[0077] Embodiment 5: reference Figure 7The utility model proposes a technical solution of a urinal with urine collection, detection and cleaning functions, including the various components in the above-mentioned embodiment. Further, the test paper storage module 9 in the urinal of this embodiment includes: a test paper box 37 and a partition plate 38, wherein the partition plate 38 is fixedly arranged in the test paper box 37 and separates it into a test paper storage area 40 and a desiccant storage area 41; wherein a discharge port is opened at the bottom of the test paper storage area 40, and the discharge port extends to the side wall of the test paper storage area close to the urine detection module (the opening height on the side wall is slightly greater than the height of a test paper box, so that only one test paper box can be pushed out at a time, not shown in the figure), and the width of the discharge port is greater than the width L1 of the positioning ear 29, and less than the width L2 of the test paper box for loading the test paper 54; so that when the test paper holder 26 moves along the long axis direction of the horizontal slide rail, it drives the test paper box at the bottom to come out of the discharge port (at this time, a test paper box originally located above the test paper box automatically falls), and continues to move to the bottom of the urine detection module for detection. With such a design (the test paper holder can be located directly below the discharge port, while all the test papers are stacked above the discharge port), there is no need to set up a separate unloading mechanism in the test paper storage module, which greatly simplifies the device and reduces costs.

[0078] Of course, in other embodiments, in order to reduce the burden on the test paper holder and keep the test paper being pushed out smoothly, the urinal also includes a discharge mechanism 39, which is arranged in the test paper storage area 40, and is used to push the test paper 54 from the test paper storage area 40 to the discharge port when needed so that it falls onto the test paper holder.

[0079] Preferably, the unloading mechanism 39 includes: a belt transmission mechanism 42, a rotating cam 43 and a positioning shaft rod 44. The belt transmission mechanism 42 is fixedly arranged on the upper part of the test paper storage area 40. The rotating cam 43 is transmission-connected with the rotating wheel 45 in the belt transmission mechanism 42, so that it has the ability to rotate around the axis of the rotating wheel 45, and is symmetrically arranged on both sides of the test paper storage area 40. The positioning shaft rod 44 is symmetrically arranged in the guide grooves 46 on both sides of the test paper storage area 40, and can be partially axially extended to the outside of the guide groove 46, and the upper end of the positioning shaft rod 44 is in contact with the convex part of the rotating cam 43, and the lower end of the positioning shaft rod 44 is in surface contact with the limiting portion 47 arranged below it, so that it has a tendency to convert vertical movement into horizontal movement, and the limiting portion 47 can partially extend radially to the inside of the test paper storage area 40 to limit the position of the test paper 54.

[0080] In this embodiment, the test paper 54 can be automatically pushed into the test paper delivery box 25 when the user needs it through the combination of the belt transmission mechanism 42, the rotating cam 43 and the positioning shaft rod 44, thereby simplifying the steps of obtaining the test paper 54 during urine testing and improving the overall convenience of use. The cooperation of the positioning shaft rod 44 and the rotating cam 43, as well as the setting of the limiting portion 47, ensures that the position of the test paper 54 inside the storage area is precisely controlled to ensure that only one test paper 54 is pushed into the delivery box each time, thereby avoiding detection errors caused by multiple test papers 54 being pushed at the same time.

[0081] On the other hand, the test paper storage area 40 can be separated from the desiccant storage area 41 by the partition plate 38, ensuring that the integrity of the test paper 54 will not be damaged due to direct contact with the desiccant. At the same time, the presence of the desiccant ensures that the storage environment of the test paper 54 is dry, preventing the test paper 54 from being damp, so as to maintain the stability and accuracy of the chemical reagent on the test paper 54.

[0082] In summary, the feeding mechanism 39 described in this embodiment realizes the automatic supply of the test paper 54, thereby reducing the direct contact between the user and the test paper 54 and reducing the risk of cross contamination. Combined with the automatic cleaning function, the entire urinal can maintain a good sanitary state during use, providing the user with a safe and sanitary urine collection and testing environment. In some embodiments, see Figure 8 The limiting portion 47 is composed of at least a first limiting portion 48 and a second limiting portion 49. The first limiting portion 48 and the second limiting portion 49 are respectively arranged at the bottom of the guide groove 46 on both sides of the test paper storage area 40, and the plane where the first limiting portion 48 is located is lower than the plane where the second limiting portion 49 is located. The second limiting portion 49 is a projection setting of the first limiting portion 48, and the inclined surfaces in the above two limiting portions 47 together form an inclined test paper 54 falling channel, so that the test paper 54 will move smoothly along a predetermined path to the test paper conveying box 25 when pushed by the unloading mechanism 39, so as to reduce the friction and jamming of the test paper 54 during the movement, and improve the smoothness and reliability of the test paper 54 conveying.

[0083] Specifically, the test paper 54 is pushed by the unloading mechanism 39 in the process of being pushed, that is, the rotating cam 43 is first driven to rotate by the operation of the belt transmission mechanism 42, and then with the rotation of the rotating cam 43, its convex part contacts the upper end of the positioning shaft rod 44, pushing the positioning shaft rods 44 on both sides to move up and down along the guide groove 46, and while the positioning shaft rods 44 move up and down, their lower ends are synchronously contacted with the first limiting portion 48 and the second limiting portion 49, driving the first limiting portion 48 and the second limiting portion 49 to contact and move closer to or away from each other in the horizontal direction. At the same time, since the plane where the second limiting portion 49 is located is higher than the first limiting portion 48, and an oblique test paper 54 falling channel is formed between the two, finally, with the axial lifting and lowering movement of the positioning shaft rod 44 along the guide groove 46, the test paper 54 located at the bottom of the test paper storage area 40 is pushed toward the test paper conveying box 25.

[0084] Preferably, the unloading mechanism 39 also includes: a cantilever 50 and a swing rod 51, the cantilever 50 is fixedly arranged on one side of the test paper storage area 40 close to the first limiting portion 48, one end of the swing rod 51 is rotatably connected to the cantilever 50, and the other end of the swing rod 51 is in contact with the protruding part of the rotating cam 43, and is located between the rotating cam 43 and the positioning shaft 44.

[0085] In this embodiment, the design of the cantilever 50 and the swing rod 51 can make the rotation of the rotating cam 43 be more accurately transmitted to the positioning shaft 44. The swing rod 51, as an intermediate component connecting the rotating cam 43 and the positioning shaft 44, can adjust the up and down movement speed and amplitude of the positioning shaft 44 according to the shape and movement characteristics of the rotating cam 43. To ensure the stability and synchronization of the test paper 54 during the pushing process, avoid the test paper 54 jamming or multiple outputs caused by the height difference between the first limiting part 48 and the second limiting part 49. At the same time, the contact position and angle of the swing rod 51 and the rotating cam 43 can be adjusted according to actual needs, so that the device can adapt to test papers 54 of different specifications or thicknesses, increasing the applicability and flexibility of the device.

[0086] On the other hand, since the plane where the first limiting portion 48 is located is lower than the plane where the second limiting portion 49 is located, such a height difference design ensures that the test paper 54 always keeps in contact with the first limiting portion 48 when it is not pushed by the unloading mechanism 39, thereby preventing the test paper 54 from accidentally sliding down or multiple test papers 54 from being pushed at the same time, so as to avoid blockage of the test paper 54 and detection errors, further improving the accuracy of urine detection, and forming an oblique test paper 54 falling channel through the two limiting portions 47, and converting the vertical movement of the positioning shaft 44 into horizontal movement along the oblique channel, so as to reduce friction and jamming during the transportation of the test paper 54, so that the test paper 54 can move smoothly along the predetermined path without blockage or multiple test papers 54 being pushed at the same time.

The display screen 53 is fixedly arranged above the urinal body 1, providing a user interaction interface for displaying instructions for use, detection results, device status information, etc.

[0088] The human infrared sensing port 52 is disposed below the display screen 53 and is used to detect the presence and position of a user so as to automatically trigger or adjust the function of the urinal.
