[0055] The present invention relates to a urine testing instrument 100, such as Figure 1 As shown, the urine tester includes a pump 6, a sampling device 5, a detection device, a control device 9, a valve 2 and a drive mechanism 3. The sampling device 5 is used to collect samples, such as urine. The outlet of the sampling device 5 is operably connected to the inlet 61 of the pump. Thus, the sample can be transported to the detection device for detection by the pump 6. The detection device includes a reagent kit 1 and a detection module 8. The reagent kit 1 contains various suitable reagents for detecting samples, such as urine, including but not limited to reagents used for conventional detection, such as urine acidity (pH), urine white blood cells (WBC / LEU), urine nitrite (NIT), urine protein (PRO), glucose (GLU), urobilinogen (URO / UBG), ketone bodies (KET), occult blood (BLU), bilirubin (BIL), ascorbic acid (VC), salts, creatinine (CrE), and reagents that can also be used for tumor markers, such as alpha-fetoprotein, carcinoembryonic antigen, albumin, urine β2-microglobulin, etc., and reagents for detecting microorganisms, such as nicotine, ethanol, vitamin C, etc.

[0056] The detection module 8 is used to detect samples, such as urine, to obtain human body related parameters. The valve 2 is used to control the opening and closing of various test kits 1. The driving mechanism 3 is used to drive the valve core 22 corresponding to the valve 2 to open or close the valve 2, thereby opening the test kit 1 to release the reagent, or closing the test kit 1; the detection module 8 includes a flow channel plate 4, and the flow channel plate 4 cooperates with the valve 2 to receive urine in the test kit 1. The control device 9 is used to control the operation of the entire urine test instrument 100, which is electrically connected to the pump 6, the driving mechanism 3 and the detection device, and can control the operation of the pump 6, the driving mechanism 3 and the detection device. The following will describe the various parts of the above-mentioned urine test instrument in detail.

[0057] The reagent kit 1 includes a mounting plate 11 and a plurality of reagent capsules 12. The mounting plate 11 has an annular body 111 and a plurality of drainage holes 113 penetrating the side of the annular body 111. The plurality of drainage holes 113 are spaced apart and distributed circumferentially along the annular body 111. The outlets of the reagent capsules 12 can be closed and connected to the corresponding drainage holes 113. The annular body 111 of the mounting plate 11 can be a closed ring or a non-closed ring, and the size and shape of the ring are not limited and can be adjusted. Figure 2a and 2b In the embodiment shown, the annular body 111 is a non-enclosed arc. It can be understood that the size of the arc of the non-enclosed annular body 111 is not affected by the Figure 2b The top of the annular body 111 is provided with a connecting portion 115 extending circumferentially toward the center of the annular body, and the connecting portion 115 is used to connect other components, such as the valve 2 of the urine test instrument.

[0058] In one embodiment, the annular body 111 is provided with a plurality of reagent tanks 112 distributed along its circumference and spaced apart from each other, the inner space of the reagent tanks 112 gradually decreases from the bottom to the top, and the inner diameter of the annular body 111 gradually decreases from the bottom to the top. Figure 2b As shown, the side of the annular body 111 that deviates from the center of the annular body 111 is defined as the outer side of the annular body 111, and the side close to the center of the annular body 111 is defined as the inner side of the annular body 111. A plurality of reagent grooves 112 are distributed at intervals on the outer side of the annular body 111, and the reagent grooves 112 are opened toward the outer side of the annular body 111 and upward. It can be understood that the opening size and direction of the reagent grooves 112 can also be adjusted without being affected by the Figure 2a and Figure 2b In addition, the number, size and spacing of the reagent tanks 112 can also be adjusted as needed. Figure 2b In the illustrated embodiment, there are multiple reagent grooves 112 of uniform size and evenly distributed on the outside of the annular body 111. The drainage hole 113 is arranged inside the reagent groove 112 and penetrates the inner side of the annular body 111 to facilitate the outflow of the reagent. The drainage hole 113 can be arranged at any position of the inner wall of the reagent groove 112, preferably close to the bottom or middle of the annular body 111 to facilitate the outflow of the reagent.

[0059] The reagent tank 112 can also be designed as a device for directly holding the reagent, such as the reagent tank 112 opening is directly closed and covered with silica gel and provided with an openable opening, the reagent can be directly placed in the reagent tank 112, and the corresponding detachable reagent capsule 12 can also be installed in each reagent tank 112, the reagent is directly stored in the reagent capsule 12, and then the reagent capsule 12 is installed in the reagent tank 112, and the reagent capsule 12 is removed and updated after use. It can be understood that the reagent capsule 12 can be detachably installed in the reagent tank 112 by magnetic suction, such as the reagent capsule 12 and the reagent tank 112 are both installed with magnets or one of them is installed with a magnet, and the other is installed with an iron sheet, and the magnet or patch can be installed with the inner wall of the reagent tank 112 or any position of the two sides. The reagent capsule 12 can also be detachably installed in the reagent tank 112 by other means, such as a plurality of card blocks are set on the reagent capsule 12, and a plurality of card slots matched with the card blocks are set in the reagent tank 112, and the reagent capsule 12 is detachably inserted into the reagent tank 112.

[0060] The reagent capsule 12 is provided with an outlet, each of the reagent capsules 12 is installed in the corresponding reagent tank 112 and its outlet is connected to the corresponding drainage hole 113, and the reagent can flow out through the outlet of the reagent capsule 12 through the drainage hole 113 of the reagent tank 112. Figure 2b As shown, each reagent tank 112 is provided with a shoulder 114 to facilitate the installation of the reagent capsule 12. The size and shape of the reagent capsule 12 match the reagent tank 112. The drainage hole 113 is provided on the inner wall of the reagent tank 112 located above the shoulder 114. The outlet of the reagent capsule 12 is provided at a corresponding position matching the drainage hole 113. It can be understood that the reagent capsule 12 can be updated in a one-time manner or designed to be reusable. The reagent capsule 12 can be made of a soft material as a whole, such as silica gel, or a soft material can be used on the side away from the inner wall of the reagent tank 112 to facilitate the reagent in the reagent tank 112 to be sucked out.

[0061] Further, the reagent kit 1 also includes a seal between the reagent capsule 12 and the reagent tank 112, and the seal is provided with a through hole connected to the drainage hole 113. It is understandable that the seal is provided on the inner wall of the reagent tank 112, and preferably covers the entire inner wall. In order to make the reagent capsule 12 and the reagent tank 112 more tightly connected, the seal needs to be made of elastic material, preferably silicone material, such as a silicone pad, so that the seal is compressed by an external force on the reagent capsule 12, which can reduce the gap between the seal and the inner wall of the reagent capsule 12 and the reagent tank 112, and can better play a sealing effect. It is understandable that the through hole of the seal is slightly larger than the outlet of the reagent capsule 12, so that the seal is compressed and squeezed in the direction of the through hole to block the outlet of the reagent capsule 12.

[0062] In another embodiment, the drainage hole 113 can be directly connected to the outlet of the reagent capsule 12, and the reagent tank 112 does not need to be provided. Figure 2c As shown, the annular body 111 is also provided with a plurality of drainage holes 113, and the outlet of the reagent capsule 12 is directly connected to the drainage hole 113. It can be understood that the reagent capsule 12 can be detachably connected to the drainage hole 113 in a variety of ways, such as the outlet of the reagent capsule 12 extending circumferentially to the outer end to form a connecting tube, and the connecting tube can be inserted into the drainage hole 113 in a sealing manner, and the mounting plate 11 is a hard material, such as plastic or ceramic; the reagent capsule 12 and the connecting tube are elastic and their shape is slightly larger than the diameter of the drainage hole 113, and the connecting tube can be made of silicone material, and it can be installed in the drainage hole 113 by applying external force to compress the connecting tube. It is also possible to set a thread in the drainage hole 113, set a thread in the outer circumference of the connecting tube, and the connecting tube is a hard material, and the connecting tube can be rotated and screwed into the drainage hole 113.

[0063] Furthermore, the annular body 11 may also be configured as a cylinder with the same inner diameter at the bottom and the top, or other irregular shapes, such as Figure 2c and 2d As shown, the bottom and top of the annular body 11 are arc-shaped with the same inner diameter, and one end of the annular drainage hole 113 is directly arranged on the side of the annular body 11, and the other end is arranged on the inner side of the annular body.

[0064] The valve 2 includes a valve body 21 and a plurality of valve cores 22. The valve body 21 is provided with a plurality of main flow channels 211 that penetrate the valve body 21 and are sequentially spaced along the length extension direction of the valve body 21. The valve body 21 is also provided with a plurality of flow outlets 212 that are respectively connected to the inner walls of the plurality of main flow channels 211; one end of each valve core 22 is slidably installed in a corresponding main flow channel 211 and can slide along the main flow channel 211, and the other end extends out of the valve body 21, and the valve core 22 can operably seal or open the flow outlet 212. In one embodiment, the driving mechanism 3 is arranged in the ring of the valve body 21 and can drive the movement of the valve core 22, which will be described in detail below.

[0065] The valve body 21 can be extended in the same direction to form a strip, or can be an irregular shape, preferably a regular shape, such as a rectangular parallelepiped or a ring. Figure 3-6 In the embodiment of the valve body 21, the valve body 21 is annular, and the side of the valve body 21 close to the annular center of the valve body 21 is defined as the inner side 2102 of the valve body, and the side away from the center of the valve body 21 is defined as the outer side 2101 of the valve body. A plurality of main flow channels 211 are arranged in sequence along the circumference of the valve body 21, with one end of the main flow channel 211 facing the inner side 2102 of the valve body, and the other end leading to the outer side 2101 of the valve body.

[0066] Furthermore, the outer side 2101 of the valve body gradually decreases radially from the bottom to the top, so that the outer side 2101 of the valve body forms an annular inclined surface to facilitate the main flow channel 211 to cooperate with other device openings.

[0067] In one embodiment, the outside of the valve body 21 cooperates with the reagent kit 1, the outer side 2101 of the valve body cooperates with the inner side of the annular body 111 of the mounting disk 11, the main channel 211 cooperates with the drainage hole 113 on the reagent kit 1 to facilitate the outflow of the reagent in the reagent kit 1, and the valve core 22 opens or closes the flow outlet 212 to realize the outflow of the reagent in the reagent kit 1.

[0068] In another embodiment, when the valve body 21 needs to cooperate Figure 2c and 2d The mounting plate 11, the outer side 2101 of the valve body can also be a cylinder, and the shape of the outer side 2101 of the valve body is not affected by Figure 3-Figure 6 The limitation of the valve body 2101 is that it needs to match different devices and the outer side 2101 of the valve body can be designed into different shapes.

[0069] Furthermore, a sealing gasket may be provided between the outer side 2101 of the valve body and the inner side of the annular body 111 to increase the closed connection between the valve body 21 and the inner side of the annular body of the mounting plate 11. The sealing gasket is also annular, and its shape matches the inner side of the reagent kit 1 and the outer side 2101 of the valve body; the sealing gasket is provided with a plurality of through holes matching the drainage holes 113 or the main flow channel 211, and the sealing gasket is preferably a silicone gasket.

[0070] Furthermore, one end of the outflow port 212 is arranged on the inner wall of the main channel 211, and the other end is arranged at the bottom of the valve body 21. The flow channel plate 4 is installed at the lower end of the valve body 21, and the flow channel plate 4 is provided with an annular flow channel 41. The other end of the outflow port 212 is located at the upper end of the annular flow channel 41. The liquid in the valve body 21 can directly flow into the annular flow channel 41 through the outflow port 212.

[0071] Furthermore, the valve body 21 is also provided with a cleaning inlet 213, an injection port 214 and a vent 215, and the cleaning inlet 213, the injection port 214 and the vent 215 are also arranged at one end on the outer side 2101 of the valve body, and the other end is opened toward the bottom of the valve body 21 and cooperates with the annular flow channel 41 of the flow channel plate 4.

[0072] Furthermore, a control valve may be provided in the cleaning inlet 213, the injection port 214 and the vent 215. The control valve is connected to the control device 9 and can open or close the cleaning inlet 213, the injection port 214 and the vent 215. Preferably, the control valves of the cleaning inlet 213 and the injection port 214 may be one-way valves, which only allow water and samples to enter the annular flow channel 41 through the cleaning inlet 213 and the injection port 214, and restrict reverse outflow. When the valve body 21 is installed in the urine test instrument 100 for use, the control valve of the vent 215 cannot use a one-way valve, which will be described in detail below.

[0073] Furthermore, a detection device installation groove 216 is provided on the top of the valve body 21 to install the detection device. The detection device installation groove 216 is a channel extending from the top to the bottom of the valve body 21, and the shape and number can be adjusted according to the number of detection devices. Figure 3-5 In the illustrated embodiment, three detection device mounting grooves 216 are provided on the valve body 21 and are all square in shape.

[0074] The shape of the main flow channel 211 can be a cylinder or other uniform shapes along the length direction, such as a uniform cylinder with a square or polygonal cross section. The shape of the valve core 22 closely matches the valve body 21 and can slide inside the valve body 21. When one end of the valve core 22 slides to the outflow port 212 and covers the outflow port 212, the valve 2 is closed; when one end of the valve core 22 is away from the outflow port 212, the valve 2 is opened, and the liquid can flow into the valve body 21 through the main flow channel 211 on the outer side 2101 of the valve body and flow through the outflow port 212. Figure 3 In the embodiment, the main channel 211 has two columnar channels with different inner diameters. The main channel 211 has at least a first channel 2111 and a second channel 2112 along its axial direction. The inner diameter of the first channel 2111 is smaller than the inner diameter of the second channel 2112. The outlet 212 is connected to the first channel 2111 and the other end extends to the bottom of the valve body 21 and is aligned with the position of the annular channel 41. The valve core 22 can slide between the first channel 2111 and the second channel 2112 and can open or close the outlet 212.

[0075] The valve core 22 is rod-shaped and its shape matches the main channel 211 and can slide in the main channel 211. The valve core 22 can be driven to seal or open the flow outlet 212 by applying external force. For example, one end of the valve core 22 can be driven to cover the flow outlet 212. When the flow outlet 212 needs to be opened, an external force can be applied to drive the valve core 22 away from the flow outlet 212. There are many ways to implement the valve core 22 to control the flow outlet 212. For example, a sealing head 2212 can be set at one end of the valve core 22. The outer diameter of the sealing head 2212 is larger than the inner diameter of the second section of the flow channel 2112. Moving the valve core 22 can cause the sealing head 2212 to open or seal the flow outlet 212.

[0076] The shape of the valve core 22 can also be various, such as cylindrical or cubic. Figure 7-Figure 9 In the illustrated embodiment, the valve core 22 is in the shape of a cylindrical rod and has at least a first core body 221 and a second core body 222. The second core body 222 is located on the side of the sealing head 2212 away from the second flow channel 2112. The outer diameter of the first core body 221 is greater than the outer diameter of the second core body 222. The outer diameter of the second core body 222 is smaller than the inner diameter of the first flow channel 2111. The length of the second core body 222 along the direction of the valve core 22 is greater than the distance from the flow outlet 212 to the second flow channel 2112. By moving the valve core 22, the sealing head 2212 can be moved away from or cover the flow outlet 212, and one end of the second core body 222 is located in the second flow channel 2112, and the other end is located in the flow outlet 212. Since the diameter of the second core body 222 is smaller than that of the first flow channel 2111, the fluid can flow into the flow outlet 212 through the second end flow channel 2112 and the second core body 222. Specifically, the end portion close to the second section of the flow channel 2112 is defined as the inner end 2201 of the valve core, and the other end is defined as the outer end 2202 of the valve core. The second section core body 222 is arranged at the end portion close to the inner end 2201 of the valve core. When an external force is applied to the first section core body 221 to move toward the outer side of the valve body 21, one end of the second section core body 222 can be located in the second section of the flow channel 2112, and the other end can be located at the flow outlet 212 position of the first section of the flow channel 2111. Since the outer diameter of the second section core body 222 is smaller than that of the second section of the flow channel 2112, the fluid can flow into the flow outlet 212 through the second section core body 222; similarly, when a force is applied to the first section core body 221 to move toward the center of the valve body 21, the inner end of the second section core body 222 can be located in the first section of the flow channel 2111, thereby sealing the flow outlet 212.

[0077] Furthermore, a sealing ring 2213 is also provided on the outer periphery of the sealing head 2212. The diameter of the sealing head 2212 can be set to be smaller than that of the first section core 221. The sealing ring 2213 can be annular and directly inserted into the sealing head 222. The outer diameter of the sealing ring 2213 is larger than that of the first section flow channel 2111 and has elasticity. Moving the valve core 22 can make one end of the sealing ring 2213 cover the first section flow channel 2111. Furthermore, the outer periphery of the sealing gasket can be set to gradually increase in the direction from the second section core 222 to the second flow channel 2111, that is, the diameter of one end of the sealing ring 2213 close to the first section flow channel 2111 is close to the diameter of the first section flow channel 2112. Moving the valve core 22 can make one end of the sealing ring 2213 stuck in the first section flow channel 2111, thereby sealing the first section flow channel 2111 and the outflow port 212.

[0078] Optionally, an elastic sealing ring can be arranged on the first section of the valve core 221 away from the second section of the valve core 222 and the sealing head 2212 to increase the sealing effect of the valve core 22. Specifically, a recessed portion 2214 recessed along the circumference of the valve core 22 is arranged on the first section of the core 221 of the second section of the core 22, and a sealing ring can be arranged circumferentially of the recessed portion 2214. The diameter of the sealing ring is slightly larger than the first section of the flow channel 2111 and is elastic to prevent the fluid from flowing out through the first section of the flow channel 2111.

[0079] The valve 2 also includes a reset member 23, such as Figure 8-9 As shown, the reset member 23 is disposed between the first core section 22 and the valve body 21 and is arranged to provide a reset force to the first core section 221. It can be understood that the reset force can be a thrust that pushes the valve core 22 away from the valve body 21, or a pulling force that drives the valve core 22 to move closer to the valve body 21, and the design is different according to the working principle of the valve 2. Figure 8 and Fig. 9 In the illustrated embodiment, the reset member 23 is disposed between the first section core body 221 and the valve body 21 and has a thrust for pushing the first section core body 221 away from the valve body 21. The reset member 23 is preferably a spring, and the external force applied to the valve core 22 can compress the spring and make the inner end 2201 and the sealing head 2212 of the valve core located in the second section flow channel 2112, so that one end of the second section core body 222 is located in the second section flow channel 2112, and the other end is located at the flow outlet 212 position of the first section flow channel 2111, and the flow outlet 212 is opened. When the external force is withdrawn, the spring can drive the inner end 2201 and the sealing head 2212 of the valve core to move toward the first section flow channel 2111, so that the sealing head 2212 blocks the first section flow channel 2111, and the flow outlet 212 is closed.

[0080] Furthermore, a limiting protrusion 2211 is also provided on the first section of the valve core 221. Specifically, the limiting protrusion 2211 is provided on the outer side 2101 of the valve core. One end of the spring can be fixedly provided on the limiting protrusion 2211, and the other end can be fixedly provided on the inner side 2102 of the valve body. The two ends of the spring can also be movably provided between the inner side 2102 of the valve body and the limiting protrusion 2211. It is only necessary to ensure that the outer diameter of the spring is smaller than the outer diameter of the limiting protrusion 22111 to prevent the first section of the core 221 from being inserted into the spring. It can be understood that the reset member 23 can also be in other forms, such as providing a magnetic strip on the inner side of the valve body 21, and providing a magnet or patch on the limiting protrusion 2211 that attracts the magnetic strip of the valve body 21, which can also achieve the effect of attraction or repulsion.

[0081] Furthermore, the valve 2 further includes a limiter 24, which is disposed outside the first section of the core 221. The limiter 24 can limit the distance that the reset member 23 pushes the valve core 22 to move, and enables the inner end 2201 of the valve core to be located between the outlet 212 and the second section of the flow channel 2112 to close the outlet 212. Figure 3-10 In the illustrated embodiment, the valve body 21 is annular, the stopper 24 is also annular, and the stopper 24 is fixedly connected to the inner side 2102 of the valve body, and a space for accommodating the reset member 23 is formed between the inner side 2102 of the valve body and the stopper 24. Specifically, the top of the valve body 21 extends circumferentially toward the center of the valve body 21 for a certain distance, the top of the stopper 24 also extends circumferentially toward the valve body 21 and is connected to the top of the valve body 21, and the reset member 23 is installed at the lower end of the top of the valve body 21 extending toward the valve core 22. It can be understood that the stopper 24 is provided with a plurality of valve core holes of a size matching the first section of the core 221 to facilitate the outer end 2202 of the valve core to extend out of the stopper 24, and an external force can be applied to the outer end 2202 of the valve core to push the valve core 22 to move.

[0082] Optionally, an elastic sealing ring can be arranged on the first section of the valve core 221 away from the second section of the valve core 222 and the sealing head 2212 to increase the sealing effect of the valve core 22. Specifically, a recessed portion 2214 recessed along the circumference of the valve core 22 is arranged on the first section of the core 221 between the second section of the core 22 and the limiting protrusion 2211, and a sealing ring can be arranged circumferentially of the recessed portion 2214. The diameter of the sealing ring is slightly larger than the first section of the flow channel 2111 and is elastic to prevent the fluid from flowing out through the first section of the flow channel 2111.

[0083] Optionally, a driving mechanism 3 may be provided at the center of the valve body 21 to drive the movement of the valve core 22 , which will be described in detail below.

[0084] The driving mechanism 3 includes a base 31, a first driving motor 32, a driving gear 33, a driven gear 34 and a second driving motor 35; the driving gear 33 is connected to the output shaft of the first driving motor 32; the driven gear 34 is rotatably connected to the base 31 and meshes with the driving gear 33; the second driving motor 35 is fixedly connected to the driven gear 34, and the output shaft of the second driving motor 35 extends along the radial direction of the driven gear 34 and can be operatively extended and retracted along the radial direction of the driven gear 34. The first driving motor 32 drives the driving gear 33 to rotate, and the driving gear 33 drives the driven gear 34 to rotate so that the position of the second driving motor 35 is continuously moved, thereby driving different external components to move. In one embodiment, the driving mechanism 3 is arranged at the ring center of the valve body 21, and the second driving motor 35 is continuously rotated to drive different valve cores 22 to move.

[0085] like Figure 10-12As shown, the driven gear 34 has a circular ring body 341, and the side of the circular ring body 341 close to the center is defined as the inner side of the circular ring body 341, and the side away from the center of the circular ring body 341 is defined as the outer side of the circular ring body 341, and the upper end of the circular ring body 341 is the top, and the lower end is the bottom; the teeth of the driven gear 34 are distributed along the top circumference of the circular ring body 341, and the driving gear 33 is arranged at the top upper end of the circular ring body 341 and rotates perpendicular to the top of the circular ring body 341, and the teeth of the driving gear 33 are perpendicular to the teeth of the driven gear 34 and are arranged at the upper end of the teeth of the driven gear 34. Specifically, the driving gear 33 rotates in the vertical direction, driving the driven gear 34 to rotate along the base 31.

[0086] Optionally, the driven gear 34 can also be arranged on the outside of the annular body 341, and the driving gear 33 is arranged to match the horizontal rotation of the driven gear 34, and the driving gear 33 can also drive the driven gear 34 to rotate along the base 31. It can be understood that the driven gear 34 can also be arranged at the bottom of the annular body 341, and the driving gear 33 can be arranged at the bottom of the corresponding annular body 341. The setting position of the driven gear 34 is not limited, and can be arranged in the circumference of the top or other positions of the top, or can be arranged at any position of the upper end or lower end of the outer side of the annular body 341. It only needs to realize that the driven gear 34 rotates along the base 31 to drive the second drive motor 35 to move.

[0087] The second driving motor 35 is arranged on the annular body 341 and moves with the rotation of the annular body 341. The outer side of the annular body 341 is provided with an inwardly recessed driving groove. The second driving motor 35 is arranged in the driving groove. The shape of the driving groove is not limited. Fig.11a In the embodiment shown, the driving groove is a circular groove. Fig.11bIn the illustrated embodiment, a mounting portion is provided on the second drive motor 35, and the mounting portion is in the shape of a rhombus and is arranged on one side close to the annular body 341, and threaded holes are provided on both sides of the mounting portion, and the driving groove matches the groove of the mounting portion to facilitate the mounting portion to be installed in the driving groove, that is, the groove with a rhombus cross section can be installed in the driving groove by bolts. The output shaft of the second drive motor 35 is arranged on the outside of the annular body 341, and the second drive motor 35 can drive its output shaft to be telescopic on the outside of the annular body 341. It can be understood that the position of the second drive motor 35 can also be adjusted as needed, such as being arranged at any position on the outside of the annular body 341, or at the bottom of the annular body 341. Optionally, the driving groove is arranged on the outer side of the annular body 341 near the top, and the upper end of the driving groove separates the driven gear 34 at the top of the annular body 341, and the teeth of the driven gear 34 form a gap at the top of the driving groove, so that the first driving motor 32 drives the moving direction of the driving gear 33 to change continuously, and the moving direction of the driven gear 34 also changes continuously, rotating clockwise to the gap and then returning clockwise. In addition, the number of the second driving motors 35 can also be adjusted, and multiple second driving motors 35 can be arranged on the annular body 341 at the same time, and each second driving motor 35 drives different parts to move.

[0088] The output shaft of the second driving motor 35 is a driving rod 351, and the driving rod 351 is arc-shaped at one end away from the second driving motor 35. It can be understood that the shape and size of the driving rod 351 can be adjusted according to the components to be driven without limitation.

[0089] The driving mechanism 3 is arranged in the valve 2, as shown in FIG. Fig.12 As shown, the first drive motor 32 is fixed to the top of the valve body 21, the base 31 is arranged at the center position of the ring of the valve body 21, the driven gear 34 is arranged in the ring of the valve body 21 and the reset member 23, and the output shaft of the second drive motor 35 is arranged to match the shape of the valve core 22. The output shaft of the second drive motor 35 is arranged at the other end of the valve core 22 and can drive the valve core 22 to seal or open the outflow port 212. By continuously rotating the driven gear 34, the second drive motor 35 can drive different valve cores 22 to move, thereby realizing the opening or closing of the valve core 22.

[0090] Furthermore, the second drive motor 35 is configured to drive the valve core 22 to move to a point where one end of the second core body 222 is located in the second flow channel 2112, and the other end is located at the flow outlet 212. It can be understood that the telescopic displacement of the output shaft of the second drive motor 35 can be adjusted according to the position of the valve core 22 and the flow outlet 212, and it is sufficient to ensure that the valve core 22 opens and closes the flow outlet 212.

[0091] Furthermore, the second drive motor 35 is configured to drive the first core body 221 to compress the spring and move toward the valve body 21 , and the driving force of the second drive motor 35 is greater than the thrust of the spring, so that the valve core 22 compresses the spring and moves.

[0092] Optionally, when a plurality of second driving motors 35 are provided on the annular body 111 , a plurality of valve cores 22 can be driven to be opened or closed simultaneously.

[0093] The flow channel plate 4 is annular, and the top of the flow channel plate 4 has at least one non-enclosed annular flow channel 41 and at least one test pit 42 formed by being recessed downward relative to the top surface, and the test pit 42 is connected to the annular flow channel 41. It can be understood that multiple annular flow channels can also be set on the flow channel plate 4, and different annular flow channels 41 have different widths and depths to facilitate the adaptation of liquids of various concentrations. In addition, the position of the test pit 42 can be connected to each annular flow channel 41 separately, or multiple annular flow channels 41 are connected to different test pits.

[0094] The annular flow channel 41 may be closed, but a barrier member needs to be provided on the annular flow channel 41 to prevent the liquid from circulating. Figure 13a-16 In the illustrated embodiment, the annular flow channel 41 is non-closed and includes a first flow channel 411 and a second flow channel 412. The end of the first flow channel 411 is provided with a bending portion 413 that is bent at a certain arc, and one end of the second flow channel 412 is connected to the bending portion 413; the test pit 42 is arranged on the second flow channel 412, and the liquid passes through the bending portion 413 when flowing into the second flow channel 412 through the first flow channel 411. The bending portion 413 can make the liquid form a vortex to generate greater fluidity and easier to enter the test pit 42. It can be understood that the bending portion 413 can bend toward the center of the annular flow channel 41, or it can be bent away from the center of the annular flow channel 41. In the embodiment shown in Figures 13-16, the bending portion 413 is bent toward the center of the annular flow channel 41, and the second flow channel 412 deviates from the arc of the first flow channel 411 and is close to the center of the annular flow channel 41.

[0095] Optionally, downwardly recessed steps 43 are provided on the top of both sides of the annular flow channel 41 to install a seal 44. Specifically, the step 43 extends along the flow direction of the annular flow channel 41 to the top of the test pit 42 and the outflow channel. The shape of the seal 44 and the step to the top of the flow channel plate 4 matches. The seal 44 can be installed on the step and can slightly protrude from the top of the flow channel plate 4. When the flow channel plate 4 is installed at the lower end of the valve body 21, the seal 43 can make the flow channel plate 4 and the valve body 21 fit tightly and make the annular flow channel 41 in a sealed state.

[0096] The arc length of the annular flow channel 41 can be adjusted as needed, and the width and depth are preferably 0.5 to 1.0 mm. In addition, in order to increase the flowability and cleanability of the annular flow channel 41, a smooth coating can be provided on the inner wall and bottom of the annular flow channel 41. The coating is preferably polytetrafluoroethylene (PTFE). In the embodiments of Figures 13-16, the annular flow channel 41 extends nearly along the entire flow channel plate 4. One end of the second flow channel 412 is connected to the bending portion 413, and the other end is provided with a liquid outlet. The liquid outlet and the end of the first flow channel 411 are separated to form a non-closed loop. The liquid outlet is connected to the liquid outlet channel 414 of the flow channel plate 4. Specifically, a bending portion 413 can also be provided between the liquid outlet and the second flow channel 412 to increase the flow of liquid in the second flow channel 412 into the liquid outlet. In the embodiment shown in Figure 13, the second flow channel 412 is bent toward the outside of the flow channel plate 4, and the liquid outlet is located on the bending portion 413 at one end away from the second flow channel 412.

[0097] The outer side of the flow channel plate 4 is provided with an inwardly recessed liquid outlet channel 414, one end of the liquid outlet channel 414 provided on the outer side of the flow channel plate 4 is a liquid outlet, and the other end is provided at the bottom of the liquid outlet end and connected to the liquid outlet end. In the embodiment shown in FIG. 13 , the liquid outlet slightly protrudes from the outer side of the flow channel plate 4 and is connected to the sewage pipe 416, and the liquid in the annular flow channel 41 can flow out through the sewage pipe 416. Specifically, one end of the liquid outlet channel 414 is connected to the annular flow channel 41, and the other end is connected to the sewage pipe 416, and the angle 4161 between the sewage pipe and the liquid outlet pipe ranges from 100° to 135° and is connected through an arc pipe, which can facilitate the smooth discharge of sewage in the annular flow channel 41 without causing backlog in the liquid outlet channel 414. The housing 10 is provided with a sewage outlet 102, which is connected to a sewage pipe 416. Specifically, a plastic tube 103 is provided in the sewage outlet 102, which can also be a silicone tube. The plastic tube 103 is closed and connected to the sewage outlet 102, and one end of the plastic tube 103 extends to the outside of the sewage outlet 102, that is, the outside of the housing 10, and the other end is connected to the sewage pipe 416, which can be sleeved outside the plastic tube 103. Further, the angle 4162 between the sewage pipe and the sewage outlet is also in the range of 100°-135° and is connected by an arc pipe to facilitate the sewage in the sewage pipe 416 to smoothly pass through the plastic pipe 103 and be discharged from the outside of the housing 10. The entire sewage pipe 416 is an arc curve and bypasses the annular reagent kit 1. After several bending arcs, the sewage flows out through the sewage pipe 416.

[0098] Further, the sewage pipe 416 is circular and preferably has a diameter of 0.5 mm. It is understandable that the diameter of the sewage pipe can also be slightly larger or smaller than 0.5 mm. The material of the sewage pipe 416 can be a hose or a hard material, preferably a silicone tube. A smooth coating is also provided in the sewage pipe 416 to facilitate the discharge of sewage, and the coating is preferably polytetrafluoroethylene. The sewage pipe 416 is detachably connected to the housing 10. Specifically, a buckle is provided on the lower shell of the housing 10, and the buckle includes a snap ring. The sewage pipe 416 can be connected to the lower shell through the snap ring, and can also be bent into a certain shape by the snap ring. It is understandable that the sewage pipe 416 can also be connected to the lower shell in other ways without limitation.

[0099] In another embodiment, a control valve is also provided in the liquid outlet channel 414, which is defined as a third control valve, and the third control is a one-way valve so that the liquid in the annular flow channel 41 can only flow into the sewage pipe 416 in one direction, and the liquid in the sewage pipe 416 is restricted from returning to the annular flow channel 41. When the urine tester is in a dormant state or is being tested, the control device can control the third control valve to close, which on the one hand makes the annular flow channel in a closed space to facilitate testing, and on the other hand closes one end of the liquid outlet channel to prevent sewage at the sewage outlet on the shell from entering the sewage pipe.

[0100] The test pit 42 can be set in multiple or single positions. Figure 13a-16 In the illustrated embodiment, there are three test pits 42 which are spaced apart on the second flow channel 412 of the annular flow channel 41. The shape of the test pits 42 is not limited, and the size can be adjusted according to the amount of reagent required for the test. In addition, the depth of the test pits 42 should not be too deep for convenience, preferably 1.0 mm. It can be understood that the test pits need to be slightly deeper than the depth of the annular flow channel to facilitate the collection of reagents in the test pits for testing.

[0101] The bottom of the flow channel plate 4 is recessed inward toward the position of the test pit 42 to form a mounting groove 415 for mounting the light source device 81 in the detection device. Figure 15-16 As shown, the mounting groove 415 corresponds to the bottom of the test pit 42, and is used to mount the photosensitive sensor 82 in the photosensitive detection device 8. The bottom of the test pit 42 needs to be a transparent material, such as transparent glass, and the photosensitive sensor 82 detects the liquid in the test pit 42 through the transparent material. Preferably, the inner diameter of the mounting groove 415 is slightly larger than the inner diameter of the test pit 42 to fully detect the liquid in the test pit 42. The shape of the mounting groove 415 is not limited and can be adjusted according to the shape of the photosensitive sensor 82.

[0102] The urine testing instrument 100 also includes a water inlet pipe 71, which also includes a first section of the water inlet pipe 71 and a second section of the water inlet pipe 71. One end of the first section of the water inlet pipe 71 is connected to the inlet 61 of the peristaltic pump, and the other end can be directly connected to an external water pipe for receiving clean water. One end of the second section of the water inlet pipe 71 is connected to the outlet 62 of the peristaltic pump, and the other end is connected to the cleaning inlet 213; further, the urine testing instrument 100 also includes a water storage container 72, which is connected to the first section of the water inlet pipe 71 for storing clean water.

[0103] The urine testing instrument 100 also includes an air pipeline 73, which also includes a first section of the air pipeline 73 and a second section of the air pipeline 73. One end of the first section of the air pipeline 73 is connected to the outlet 62 of the pump 6, and the other end receives external air; one end of the second section of the air pipeline 73 is connected to the outlet 62 of the peristaltic pump, and the other end is connected to the vent 215.

[0104] The pump 6 of the present invention is preferably a peristaltic pump 6, such as Fig.17 , Fig.18 and Fig.19 As shown, the peristaltic pump 6 has an inlet 61 and an outlet 62, and a hose is also provided inside the peristaltic pump, and the air or liquid flow channel is driven by squeezing the hose; specifically, a first control valve is provided upstream of the inlet 61 of the peristaltic pump and is configured to selectively open the sampling pipeline 51 or the water inlet pipeline 71 or the air pipeline 73, and a second control valve is provided downstream of the outlet 62 of the peristaltic pump and is configured to selectively open the injection port 214 or the cleaning inlet 213 or the vent 215. Specifically, when sampling is required, the first control valve connects the inlet 61 of the peristaltic pump with the first section of the sampling pipeline 51, and the second control valve connects the outlet 62 of the peristaltic pump with the second section of the sampling pipeline 51. At this time, the control device 9 controls the valve of the injection port 214 to open, and controls the liquid outlet pipeline. The valve is closed; when cleaning is required, the first control valve switches the inlet 61 of the peristaltic pump to the first section of the water inlet pipe 71, and the second control valve connects the outlet 62 of the peristaltic pump to the second section of the water inlet pipe 71, and the control device 9 controls the valve of the cleaning inlet 213 to open, and controls the valve of the liquid outlet channel 414 to close; when ventilation or suction is required, the first control valve connects the inlet 61 of the peristaltic pump to the first section of the air path pipe 73, and the second control valve connects the outlet 62 of the peristaltic pump to the outlet 62 of the peristaltic pump, and when the air in the flow channel plate 4 needs to be discharged, the valves of the inlet 214, the vent 215 and the liquid outlet channel 414 are all closed; when ventilation is required to drive the sewage in the flow channel plate 4 to be discharged, the control device 9 controls the valve of the liquid outlet channel 414 to open. Optionally, the first control valve and the second control valve are both solenoid valves.

[0105] The urine tester 100 also includes a housing 10. Fig. 20As shown, the housing 10 has a containing space to accommodate the pump 6, the sampling device 5, the detection device, the valve 2, the driving mechanism 3 and the control device 9. Specifically, the housing 10 has an upper shell and a lower shell, the upper shell and the lower shell are detachably and hermetically connected to form a closed space, the lower shell is fixedly arranged on the inner wall of the toilet, and at least one urine inlet 101 is arranged on the upper shell, and the urine inlet 101 is connected to the sampling pipeline 51, specifically, the urine inlet 101 is connected to the first section of the sampling pipeline 51 to receive urine; the upper shell or the lower shell is also provided with a ventilation inlet and connected to the first section of the air path pipeline 73; the housing 10 is also provided with a sewage outlet, which is arranged on the lower shell or at the connection between the upper shell and the lower shell to facilitate the passage of the sewage pipeline 416.

[0106] The urine test instrument 100 also includes a temperature sensor, which is arranged on the shell 10 and electrically connected to the control device 9. Specifically, the temperature sensor is arranged inside or outside the upper shell to sense the temperature and thus start the urine test instrument 100. It is preferably arranged outside the upper shell to more accurately sense the urine temperature. The temperature sensor sends a signal to the control device 9, and the control device 9 starts the entire urine test instrument 100 to start operation.

[0107] The urine test instrument 100 also includes an indicator light to display the working status of the urine test instrument 100. There can be one or more indicator lights, which can be set on the upper shell or at other positions of the shell 10, as long as they can be easily seen.

The light source device 81 and the photosensitive sensor 82 are respectively arranged at the corresponding positions of the test pit 42 on the flow channel plate 4. Specifically, the light source device 81 is arranged in the mounting groove 415 at the bottom of the flow channel plate 4. The top of the mounting groove 415 corresponds to the test pit 42, and the top of the mounting groove 415 is a transparent material that can transmit light. The LED light is installed in the mounting groove 415 to generate a light source to the photosensitive sensor 82; the photosensitive sensor 82 is arranged in the detection device mounting groove 216 of the valve body 21, and the valve body 21 is connected to the flow channel. After the plate 4, the detection device installation groove 216 is located at the upper end of the test pit 42, and can receive the light source after the LED irradiates the urine and reagent mixed liquid for detection. It can be understood that the LED and the like can also be set on the side of the test pit 42, and the photosensitive sensor 82 is set on the opposite side of the test pit 42. The sides of the test pit 42 are all surrounded by transparent materials, and the photosensitive sensor 82 can also receive the LED light source; the LED light can also be set on the top of the test pit 42, and the photosensitive sensor 82 is set at the bottom of the test pit 42, which can also achieve the purpose of detection; the position of the LED and the photosensitive sensor 82 is in many ways and is not limited. It can be understood that the photosensitive sensor 82 is connected to the external equipment and control device 9, and after the urine and reagent flow through the test pit 42, the control device 9 controls the LED and the photosensitive sensor 82 to start. After the detection is completed, the control device 9 controls the LED and the photosensitive sensor 82 to turn off and transmit the data to the external equipment.

[0110] The sampling device 5 includes a sampling pipeline 51, which is divided into a first section sampling pipeline 51 and a second section sampling pipeline 51, wherein one end of the first section sampling pipeline 51 is connected to the inlet 61 of the peristaltic pump, and the other end is used to receive urine; one end of the second section sampling pipeline 51 is connected to the outlet 62 of the peristaltic pump, and the other end is connected to the inlet 214 of the valve body 21; the peristaltic pump 6 forms a negative pressure in the sampling pipeline 51 by exhausting air, thereby absorbing urine into the first section sampling pipeline 51, which can drive the reception of urine, and can also drive urine into the second section sampling pipeline 51 and enter the annular flow channel 41 through the inlet 214.

[0111] Furthermore, the sampling device 5 also includes a sample container 52, which is connected to the first section of the sampling pipe 51. The driving pump 6 can drive the urine to flow into the sample container 52 first, and then drive a certain amount of urine to flow into the annular channel; optionally, a filter is also provided in the sample container 52, and the urine is first filtered after entering the sample container 52 to prevent other solid substances from entering the annular flow channel 41 to interfere with the test.

[0112] exist Fig.17 and 18In the illustrated embodiment, the reagent box 1 of the urine test instrument 100 is annular, and the valve 2 and the driving mechanism 3 are sequentially installed in the ring of the reagent box 1, wherein the valve body 21 is installed on the inner ring of the annular body, the valve core 22 is installed in the main flow channel 211 of the valve body 21, and the outer end 2202 of the valve core extends out of the valve body 21 and is located on the inner side 2102 of the valve body, and the driving mechanism 3 is installed in the ring of the valve body 21, wherein the first driving motor 32 is installed on the top of the valve body 21, and the driven gear 34 and the second driving motor 35 are installed on the center of the valve body 21 and the driving rod 351 of the second driving motor 35 can drive the valve core 22 to move. Specifically, the first driving motor 32 drives the driving gear 33 and drives the driven gear 34 to rotate. The first driving motor 32 is configured to rotate a certain angle and stay for a period of time. It can be understood that the rotation angle and the staying position are matched with the distance of each valve core 22, and the staying time also needs to be designed according to the second driving motor 35 driving the valve core 22 and the reagent outflow amount and outflow speed in the reagent box 1. When the output shaft of the second driving mechanism 3 rotates along with the driven gear 34 to the valve core 22 corresponding to the reagent capsule 12 that needs to be opened, the second driving mechanism 3 drives the output shaft to extend out from the driven gear 34 and push the valve core 22 to move toward the valve body 21. It can be understood that the telescopic length of the output shaft also needs to be determined according to the position of the second section core 222 of the valve core 22 and the outflow port 212. It is necessary to ensure that one end of the second section core 222 of the valve core 22 is located in the second section flow channel 2112, and the other end is located in the outflow port 212. After the reagent in the reagent box 1 flows out through the outflow port 212, the second driving motor 35 retracts, and the reset member 23 drives the valve core 22 to move away from the valve body 21. The inner end 2201 of the valve core blocks the first section flow channel 2111 and the outflow port 212, and the outflow port 212 is closed.

[0113] The flow channel plate 4 is installed at the bottom of the valve body 21, and the flow channel plate 4 and the valve body 21 are closely matched. It can be understood that the flow channel plate 4 can be welded or screwed to the valve body 21, or can be fixedly connected by other means. The connection method is not limited, and it is only necessary to ensure that the top of the flow channel plate 4 is closed and connected to the valve body 21. Fig.17 In the embodiment, the flow channel plate 4 is connected to the valve body 21 by screws. The valve body 21 is provided with a plurality of outflow ports 212, one end of each of which is connected to the inner wall of each of the plurality of main channels 211, and the other end of each of which corresponds to the annular flow channel 41 of the flow channel plate 4 at the bottom of the valve body 21. The valve body 21 is also provided with a cleaning inlet 213, an injection port 214 and a vent 215 connected to the annular flow channel 41, wherein urine can flow into the annular flow channel 41 through the injection port 214, clean water can flow into the annular flow channel 41 through the cleaning inlet 213, and air can enter the annular flow channel 41 through the vent 215.

[0114] The reagent in the reagent box 1 can flow into the annular channel 41 through the main channel 211 of the valve body 21 and the outflow port 212. Since the flow channel plate 4 and the valve body 21 are closed, the valve body 21 and the mounting disk 11 are also closed. After the driving mechanism 3 drives the valve core 22 to open the outflow port 212, the pump 6 sucks away the air in the annular track through the air vent 215, which will form a negative pressure state in the annular track 41 and in the second section of the flow channel 2112. The reagent in the reagent box 1 can be affected by the negative pressure and can be adsorbed into the annular track. It can be understood that at this time, the cleaning inlet 213, the sample injection port 214 and the liquid outlet channel 414 are closed, leaving only the air vent 215 in an open state to discharge the air in the annular flow channel 41. Valves are provided in the sample inlet 214, the cleaning inlet 213, the vent 215 and the liquid outlet channel 414, which may be control valves or other valves. The valves are connected to the control device 9 and are controlled by the control device 9 for operation. For example, when urine needs to be input into the annular flow channel 41, the valve of the sample inlet 214 is opened, and the valves of the cleaning inlet 213 and the vent 215 can be opened or closed without being affected. The valve of the liquid outlet channel 414 must be in a closed state to prevent the liquid from flowing out directly without being tested; when the liquid enters the annular flow channel 41, the vent 215 is opened to input air to drive the urine into the test pit 42, and at this time, the cleaning inlet 213 and the sample inlet 214 also need to be closed; after cleaning is required, the cleaning inlet 213 is opened, and the liquid outlet channel 414 is also opened, and water enters the annular flow channel 41 and flows out through the liquid outlet channel 414 to clean the entire device.

It can also first control the driving mechanism 3 to drive the valve core 22 to open the flow outlet 212, and then control the pump 6 to start, and the order of sequence will not be affected.

[0120] It can be understood that when the first control valve connects the gas circuit pipeline 73 to the pump 6, the control device 9 simultaneously controls the valve in the air inlet to open, and at the same time the valves of the sample inlet 214 and the cleaning inlet 213 are closed to form a closed space to prevent air from being discharged from the sample inlet 214 and the cleaning inlet 213.

When cleaning is required, the pump 6 drives the water in the water storage container 72 to flow into the flow channel plate 4.

When the flow channel plate 4 needs to be cleaned, the control device 9 simultaneously drives the valve of the cleaning inlet 213 to open to facilitate the water in the water inlet pipe 71 to flow into the flow channel plate 4.
