DETAILED DESCRIPTION

[0052] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other arbitrarily without conflict.

[0053] The embodiment of the present application provides a test paper storage device 1, such as Figure 1-Figure 6 As shown, it comprises: a roller 11, which is arranged to be rotatably mounted, and a plurality of sliding mounting structures 111 are arranged on the roller 11 at intervals along the circumferential direction, and each sliding mounting structure 111 is arranged to be used for slidingly mounting a test paper assembly 6; wherein the sliding mounting structure 111 is arranged so that the test paper assembly 6 can be pushed out of the roller 11 along the axial direction of the roller 11, and can be pushed back into the roller 11. wherein the test paper assembly 6 is an assembly for detecting a test liquid (such as urine).

[0054] The test paper storage device 1 provided in the embodiment of the present application stores a plurality of test paper assemblies 6 when in use. When the test paper assemblies 6 are used for testing, the test paper assemblies 6 are pushed out of the drum 11. After the test paper assemblies 6 are tested, the used test paper assemblies 6 can be pushed back to the drum 11 to realize the recycling of discarded test paper. The test paper storage device 1 can be applied to urine testing equipment in toilets.

[0055] The technical solution provided by the embodiment of the present application can push one of the test paper assemblies 6 from the roller 11 to the detection position through the pushing device when the test paper assembly 6 is used for detection. After the test paper assembly 6 is detected, the used test paper assembly 6 can be pushed back to the roller 11 to realize the recycling of the discarded test paper assembly 6. In the process of use, the roller 11 can be set to rotate in one direction, referring to Figure 5 Every time it rotates a certain angle, one of the unused test paper assemblies 6 is aligned with the pushing device, and the pushing device can push the unused test paper assembly 6 to the detection position. After the detection is completed, the pushing device pushes the used test paper assembly 6 back to the roller 11. The test paper assembly 6 is used repeatedly for detection. After the multiple test paper assemblies 6 on the roller 11 are used up, the roller 11 is loaded with the used and discarded multiple test paper assemblies 6, and then the roller 11 can be processed centrally.

[0056] Therefore, by using the test paper storage device 1 provided in the present application, the test paper assembly 6 is easy to use and convenient to operate, and the discarded test paper assemblies are returned to the drum 11 for centralized treatment, which can solve the problem of environmental pollution caused by discarded test papers being used once and then discarded in the prior art.

[0057] In one embodiment, the sliding mounting structure 111 is a plurality of slide grooves provided on the outer surface of the drum 11. The test paper assembly 6 can slide into and out of the slide grooves. To prevent the test paper assembly 6 from slipping out of the top opening of the slide groove, the side walls on both sides of the slide groove can be arranged to be inclined toward each other from bottom to top, so that the test paper assembly 6 can only enter and exit from the opening at one end of the slide groove.

[0058] It is understandable that the sliding installation structure 111 can also be other structures. For example, it can be a ridge set on the outer surface of the roller 11, and a groove is set on the test paper assembly 6. The ridge can cooperate with the groove of the test paper assembly 6 for sliding installation.

[0059] In one embodiment, Figure 3-Figure 5 As shown, a center hole 112 and an open slot 113 extending from the center hole 112 to one side of the drum 11 are provided at the center position of the drum 11 .

[0060] The central hole 112 and the opening slot 113 can be provided to facilitate the installation of the drum 11 on the rotating shaft. The opening slot 113 is aligned with the rotating shaft, and the drum 11 is moved relative to the rotating shaft, so that the rotating shaft enters the central hole 112 through the opening slot 113, thereby achieving the installation of the drum 11 and the rotating shaft. In some examples, a motor can be provided to drive the rotating shaft to rotate, and the rotating shaft is driven to rotate by the motor, so that the rotating shaft drives the drum 11 to rotate.

[0061] In one embodiment, Figure 1-Figure 3 As shown, the test paper storage device 1 further includes a cover 12, which is arranged to cover the outside of the drum 11, so as to prevent the multiple test paper assemblies 6 on the drum 11 from being contaminated. The cover 12 is provided with an axial opening 1212 extending along the axial direction of the drum 11, and the test paper assembly 6 is pushed out of the drum 11 and pushed back into the drum 11 through the axial opening 1212 (refer to Figure 5 and Figure 6 ).

[0062] In one example, the housing 12 includes a cylinder 121 and end plates 122 located at both ends of the cylinder 121 , wherein the cylinder 121 has a chamber 1211 with a circular cross-section, and the drum 11 is located in the chamber 1211 .

[0063] To facilitate the placement and installation of the test paper storage device 1, as Figure 2 and Figure 3 As shown, the housing 12 may further include a bottom plate 123 located at the bottom of the cylinder 121 and located on both sides of the axial opening 1212. The housing 12 may further include a fixing portion 124 provided at the end of the cylinder 121 and radially protruding from the outer surface of the cylinder 121, and a connecting rib 125 connecting the fixing portion 124 at both ends, wherein the end plate 122 located at at least one end of the cylinder 121 may be fixed to the fixing portion 124 by bolts. The fixing portion 124 at the bottom of the cylinder 121 is connected by the bottom plate 123 as a connecting rib. The fixing portions 124 in a right angle are respectively provided at the four corners of the two ends of the cylinder 121, and after the connecting rib 125 connects the fixing portion 124, the housing 12 is roughly a square structure.

[0064] exist Figure 1-Figure 3 In the example shown, a center hole 112 and an open slot 113 extending from the center hole 112 to one side of the drum 11 are provided at the center of the drum 11, so that the drum 11 and the rotating shaft are installed through the open slot 113 and the center hole 112. To avoid interference between the cover 12 when the test paper storage 1 and the rotating shaft are installed, the end plates 122 of the cover 12 at both ends of the drum 11 are further provided with end openings 1221, respectively, and each end opening 1221 extends from a position corresponding to the center hole 112 to communicate with the axial opening 1212.

[0065] When the test paper storage device 1 is placed, a support body 13 may be placed underneath. The support body 13 is inserted into the axial opening 1212 of the housing 12 and extends into the opening groove 113 of the drum 11 . The support body 13 may prevent the drum 11 from rotating relative to the housing 12 .

[0066] The test paper storage 1 may include a plurality of test paper assemblies 6 , and the plurality of test paper assemblies 6 are mounted on the sliding mounting structure 111 of the drum 11 in a one-to-one correspondence.

[0067] Among them, the test paper assembly 6 is configured to be pushed out from the bottom of the drum 11. Specifically, a pushing device can be provided at the bottom of the test paper storage device 1. When one of the test paper assemblies 6 of the drum 11 rotates to the bottom and corresponds to the pushing device, the pushing device can push out the corresponding test paper assembly 6 and push the used test paper assembly 6 back to the drum 11 after the test paper assembly 6 is tested.

[0068] In one embodiment, the structure of the test paper assembly 6 is as follows: Figure 23-Figure 28 , comprising a loading body 61, a reaction layer 62 mounted on the loading body, and a diaphragm layer 63 on the side of the reaction layer 62 away from the loading body 61; wherein, when the test paper assembly 6 is mounted on the drum 11, the side with the diaphragm layer 63 faces radially inward. In this way, when the test paper assembly 6 is pushed out from the bottom of the test paper storage 1, the side with the diaphragm layer 63 faces upward, and the diaphragm layer 63 can be pierced from above, and then the urine drop test can be performed.

[0069] The embodiment of the present application also provides a urine testing device, including the above-mentioned test paper storage device 1. The urine testing device can be installed on a toilet to test urine, of course, it is not limited to being installed on a toilet, and can also be applied to other scenarios to test other test liquids that need to be tested.

[0070] like Figure 7-Figure 11 In the illustrated embodiment, the urine testing device further comprises a mounting body 2 and a pushing device 4, the test paper storage device 1 is mounted on the mounting body 2, and the drum 11 is rotatable relative to the mounting body 2, when one of the test paper assemblies 6 on the drum 11 is rotated to correspond to the pushing device 4, the pushing device 4 pushes the test paper assembly 6 axially from the drum 11 to the testing position, and after the testing is completed, the test paper assembly 6 can be pushed back from the testing position to the drum 11.

[0071] The urine testing device may further include a driving device 3 , wherein the driving device 3 is configured to drive the roller 11 to rotate relative to the mounting body 2 .

[0072] In one example, if Fig.11 As shown (combined Fig.15 and Fig.16), the driving device 3 includes a rotating shaft 32 rotatably mounted on the mounting body 2 and a driving motor 31 driving the rotating shaft 32 to rotate; the test paper storage 1 is configured to be detachably mounted on the rotating shaft 32, and when the test paper storage 1 is mounted on the rotating shaft 32, the rotating shaft 32 drives the roller 11 to rotate. Therefore, after the multiple test paper assemblies 6 on the test paper storage 1 are used, the test paper storage 1 can be removed from the rotating shaft 32 to replace a new test paper storage 1, or the used test paper assemblies 6 can be centrally processed and replaced with new test paper assemblies 6.

[0073] In this example, a center hole 112 and an opening groove 113 extending from the center hole 112 to one side of the roller 11 are provided at the center of the roller 11 of the test strip storage device 1. The roller 11 allows the rotating shaft 32 to enter the center hole 112 through the opening groove 113, and the roller 11 can be removed from the rotating shaft 32 through the opening groove 113.

[0074] In order to enable the rotating shaft 32 to drive the drum 11 to rotate, a radially protruding protrusion 321 (see Fig.16 ), the protrusion 321 is located in the opening groove 113, so that when the rotating shaft 32 rotates, the protrusion 321 applies a rotational torque to the drum 11 to drive the drum 11 to rotate. Of course, the rotating shaft 32 and the center hole 112 of the drum 11 can also be arranged to be mutually matched polygonal structures, so that the rotation of the rotating shaft 32 can also drive the drum 11 to rotate.

[0075] The test paper storage device 1 further comprises a cover shell 12 covering the roller 11, and an axial opening 1212 is provided on the cover shell 12. The end plates 122 of the cover shell 12 at both ends of the roller 11 are also respectively provided with end openings 1221, and each end opening 1221 extends from a position corresponding to the center hole 112 to communicate with the axial opening 1212. In this way, when the roller 11 of the test paper storage device 1 is installed on the rotating shaft 32 through the opening groove 113, the axial opening 1212 and the end opening 1221 of the cover shell 12 can avoid the rotating shaft 32; wherein, the pushing device 4 is configured to push the test paper assembly 6 out of the roller 11 and push it back into the roller 11 from the axial opening 1212 of the cover shell 12.

[0076] exist Figure 7 -and Fig.16 In the example shown, the installation body 2 includes a box structure 21 with an upper opening, and a rotating shaft 32 is located in the box structure 21. The test strip storage 1 is configured to move downward from the upper opening into the box structure 21 and the roller 11 is installed on the rotating shaft 32 through the opening slot 113 when the roller 11 moves downward to a certain position. The state of the test strip storage 1 after being installed in the box structure 21 is as follows: Figure 7-Figure 10 To facilitate taking the test paper storage device 1 out of the box structure 21, a hand-held portion 126 (see FIG. Figure 1 ).

[0077] In one embodiment, the installation body 2 further includes a base 22, and the box structure 21 is installed on the base 22. Fig.17 and Fig.18 As shown, one end of the base 22 is provided with two mounting posts 221, and the other end is provided with two mounting portions 222. The box structure 21 can be fixed to the mounting posts 221 and the mounting portions 222 by bolts. A pushing device 4 is provided on the base 22. The pushing device 4 is arranged on the base 22 below the box structure 21, and the pushing device 4 can push the test paper storage 1 to rotate to the test paper assembly 6 at the bottom, as shown in FIG. Fig.14 It is shown that the push claw 44 of the pushing device 4 located below the drum 11 is facing the test paper assembly 6 located at the bottom of the drum 11, and the push claw 44 can push the test paper assembly 6 at the bottom to move back and forth.

[0078] refer to Figure 17-Figure 18 In the example of FIG. 4 , the pushing device 4 includes a moving frame 43 and a pushing mechanism for driving the pushing frame 43 to move back and forth. The moving frame 43 is provided with a pushing claw 44, and the pushing claw 44 pushes the test paper assembly 6 out of the roller 11 and pushes it back to the roller 11. It should be noted that the “pushing back the roller” described in this application refers to pushing the test paper assembly 6 to the installation position of the sliding installation structure 111 of the roller 11.

[0079] The pushing mechanism may include a pushing motor 41 and a lead screw 42 driven to rotate by the pushing motor 41. The moving frame 43 is installed on the lead screw 42 by threads. When the lead screw 42 rotates in the forward direction, the moving frame 43 moves forward, so that the push claw 44 pushes the test paper assembly 6 from the roller 11 to the detection position. When the lead screw 42 rotates in the reverse direction, the moving frame 43 retreats, thereby driving the push claw 44 to push the test paper assembly 6 back to the roller 11. The test paper assembly 6 is provided with a pushing groove 611 (refer to Fig.23 ), the push claw 44 extends into the push groove 611 to push the test paper assembly 6 to move back and forth.

[0080] In order to ensure the smooth movement of the moving frame 43 , a guide rod 45 may be further provided on the base 22 , and the moving frame 43 moves along the lead screw 43 and the guide rod 45 .

[0081] In one embodiment, the urine detection device further includes a first position sensor 85, a second position sensor 86 and a position sensor 84, wherein the position sensor 84 is mounted on the moving frame 43, and the first sensor 85 and the second sensor 86 are both mounted on the mounting body 2 and are respectively located on both sides of the moving frame 43 in the moving direction. Fig.11 As shown, you can also refer to Fig.17 and Fig.18 , Fig.17 and Fig.18 The installation of the position sensor 84 and the first position sensor 85 is shown, while the second position sensor 86 is not shown.

[0082] When the movable frame 43 moves from the first position to the second position so as to push one of the test paper assemblies 6 from the roller 11 to the detection position, as shown in FIG. Fig.11 and Fig.18 In the state shown, the second position sensor 86 and the position sensor 84 generate induction, and the pushing mechanism stops pushing; when the moving frame 43 moves from the second position to the first position to push the test paper assembly 6 back to the roller 11 from the detection position, as shown in FIG. Fig.12 and Fig.17 In the state shown, the first position sensor 85 and the position sensor 84 generate induction, and the pushing mechanism stops pushing. The test paper detection device includes a controller, and the controller controls the pushing mechanism to stop after receiving the sensing information of the first position sensor 85 and the position sensor 84, or receiving the sensing information of the second position sensor 86 and the position sensor 84.

[0083] The urine detection device may further include a roller sensor 81 mounted on the mounting body 2, and the roller sensor 81 is used to detect whether the roller 11 is mounted on the mounting body 2. When the controller receives the sensing information that the roller sensor 81 senses the roller 11, the driving device 3 and the pushing device 4 will be controlled to act.

[0084] The urine detection device further includes an angle sensor 83, and the angle sensor 83 is configured to detect the rotation angle of the drum 11. Fig.16 As shown, an angle positioning grating 82 is provided on the box structure 21 of the installation body 2, and the angle sensor 83 determines the rotation angle of the drum 11 by acquiring the light signal of the angle positioning grating 82. When it is detected that the drum 11 rotates to a predetermined angle, the controller controls the drum 11 to stop rotating. At this time, one of the test paper assemblies 6 on the drum 11 rotates to correspond to the pushing mechanism 4.

[0085] In addition, the urine testing device may also be installed on the dehumidification fan 5 on the installation body 2, which helps the dehumidification fan 5 to remove moisture from the device.

[0086] In one embodiment, Figure 7-Figure 8 as well as Figure 19-22 As shown, the urine detection device may further include a drop detection device 7, and the drop detection device 7 includes:

[0087] The detection chamber 71 has an inlet 712 and a chamber 711 connected to the inlet 712. The pushing device 4 pushes the test paper assembly 6 from the roller 11 and pushes it into the chamber 711 from the inlet 712 to reach the detection position; the detection chamber 71 also has a dripping port 713, and the detection liquid is dripped from the dripping port 713 to the test paper assembly 6 located in the chamber 711, so that the detection liquid contacts the reaction layer of the test paper assembly 6;

[0088] At least one detector 714 is disposed in the chamber 711 (refer to Fig.13 ) is used to detect the reaction information of the test paper assembly 6 after contacting the detection liquid.

[0089] After the pushing device 4 pushes the test paper assembly 6 from the entrance 712 into the chamber 711 of the detection chamber 71, the detection liquid is dripped from the dripping port 713 to the test paper assembly 6, so that after the test paper assembly 6 reacts with the detection liquid, the detector 714 in the chamber 711 can detect the reaction information of the test paper assembly 6, so as to obtain the detection result. It is simple and convenient to use the drop detection device 7 to detect the detection liquid (such as urine), which reduces the difficulty of use for users and is conducive to improving the detection efficiency. Moreover, the test paper assembly 6 and the detector 714 are integrated in the chamber 711 of the detection chamber 71 for detection, which can reduce pollution and help improve the stability and accuracy of the detection.

[0090] In one embodiment, reference Figure 23-Figure 28 As shown, the test paper assembly 6 includes a loading body 61, a reaction layer 62 mounted on the loading body, and a diaphragm layer 63 on a side of the reaction layer 62 away from the loading body 61;

[0091] When the test paper assembly 6 is installed on the roller 11, the side with the diaphragm layer 63 faces radially inward, and the pushing device 4 is configured to push the test paper assembly 6 located at the bottom of the roller 11 into the chamber 711, thereby pushing the side of the test paper assembly 6 with the diaphragm layer 63 in the chamber 711 upward. In this way, the diaphragm layer 63 can be punctured and liquid can be dripped on the upward side of the test paper assembly 6.

[0092] The drop detection device 7 further includes a puncture drop assembly 72 , which is configured to puncture the diaphragm layer 63 on the test paper assembly 6 from the drop opening 713 and then drop liquid, so that the detection liquid contacts the reaction layer 62 .

[0093] In one example, reference Figure 23-Figure 28As shown, the loading body 61 of the test paper assembly 6 is provided with a mounting groove 617 and a dripping groove 612 connected to the mounting groove 617, and the detection liquid dripped from the dripping groove 612 can flow into the mounting groove 617 to achieve contact with the reaction layer 62. In addition, an exhaust groove 614 connected to the mounting groove 617 can be provided on the loading body 61. Through the exhaust groove 614, the exhaust can be exhausted, so that the dripping liquid can flow smoothly along the mounting groove 617, so that the detection liquid can fully contact with the reaction layer 62. Therefore, in order to achieve dripping into the dripping groove 612 so that the dripping liquid contacts the reaction layer 62 of the test paper assembly 6, a puncture component can be provided to puncture the dripping groove 612 and the diaphragm layer 63 above the exhaust groove 614. When the test paper assembly 6 moves into the chamber 711 of the detection chamber 71, the exhaust groove 614 and the dripping groove 612 correspond to the dripping port 713 of the detection chamber 71, so that the dripping groove 612 and the exhaust groove 614 are punctured and dripped from the dripping port 713, and the dripping groove 612 and the exhaust groove 614 can also be used to store excess test liquid. In addition, a desiccant groove 618 for placing a desiccant 64 can also be provided on the loading body 61, and the desiccant 64 keeps the test paper assembly 6 dry to prevent moisture and the like from affecting the detection accuracy.

[0094] In one example, if Fig. 22 As shown, the puncture and drip assembly 72 includes a lifting frame 723, a drip tube 724 installed on the lifting frame 723, and a lifting mechanism for driving the lifting frame 723 to move up and down. When the lifting frame 723 descends to a predetermined height position, the drip tube 724 punctures the diaphragm layer 63 of the test paper assembly 6 corresponding to the drip groove 612 and drips liquid into the drip groove 612.

[0095] The puncture and drip assembly 72 also includes a puncture and exhaust component 725 installed on the lifting frame 723. The puncture and exhaust component 725 is configured to puncture the diaphragm layer 63 of the test paper assembly 6 corresponding to the exhaust groove 614 when the lifting frame 723 descends to a predetermined height position to exhaust the exhaust groove 614.

[0096] The lifting mechanism may include a lifting motor 721 and a cam 722 driven to rotate by the lifting motor 721. When the cam 722 rotates to a position where the protrusion is downward, it pushes the lifting frame 723 down to the predetermined height position. The lifting mechanism also includes a return spring (not shown in the figure). When the protrusion of the cam 722 rotates upward, the return spring bounces the lifting frame 723 upward to the initial position.

[0097] The puncture and drip assembly 72 further includes a mounting bracket 727 fixed relative to the detection chamber 71, the lifting motor 721 is mounted on the mounting bracket 727, the lifting frame 723 is slidably mounted on the mounting bracket 727, and the drip tube 724 and the puncture exhaust component 725 on the lifting frame 723 correspond to the drip port 713 of the detection chamber 71. The mounting bracket 727 can be mounted on the support frame 23 of the installation body 2, such as Figure 7 and Figure 8 shown.

[0098] In addition, the puncture drip assembly 72 may further include a waste liquid discharge component 726 installed at the drip port 713 , and the excess test liquid dripped by the drip mechanism to the test paper assembly 6 flows into the waste liquid discharge component 726 .

[0099] In one embodiment, a light source is disposed in the chamber 711 to provide light for detection by the detector.

[0100] In one embodiment, at least one detector 714 in the chamber 711 includes a color detector for acquiring the color of the test paper assembly 6, and the test liquid is analyzed through the color information acquired by the color detector.

[0101] When a test liquid, such as urine, is dropped onto the test paper assembly 6, the reaction layer 62 of the test paper assembly 6 comes into contact with the urine, and the chemical components of the reaction layer 62 react with the urine to cause a color change, the depth of the color being proportional to the concentration of the corresponding substance in the urine. Therefore, by detecting the color information of the test paper assembly 6, the composition of the urine can be detected.

[0102] Among them, Fig.24 As shown, the reaction layer 62 of the test paper assembly 6 may include a plurality of area blocks, each of which has a different reaction indicator for detecting different components of urine. For example, the plurality of area blocks are respectively used to detect pH value, specific gravity, leukocytes, glucose, etc. in urine. Accordingly, the detector is provided with a plurality of Fig.12 and Fig.13 As shown, a plurality of detectors 714 are arranged in the detection chamber 71, and each detector 714 corresponds to detecting an area block, thereby detecting a component or index in urine.

[0103] In order to position the reaction layer 62 in the mounting groove 617 so that the multiple area blocks can correspond to the multiple detectors one by one, a positioning block is provided on the carrier body 61. Figure 25-27As shown, a plurality of intermediate stop blocks 615 are arranged in the middle of the installation groove 617, and two long reaction layers 62 are respectively installed on both sides of the intermediate stop blocks 615. One end of the reaction layer 62 close to the drip groove 612 is limited by the end wall of the groove, and the other end is limited by an end stop block 616. In addition, in order to allow the detection liquid to fully contact with each area block, the drip groove 612 is connected with a flow channel 613, and the flow channel 613 extends to the end of the installation groove 617 away from the drip groove 612. The detection liquid dripped from the drip groove 612 first flows to the end of the installation groove 617 away from the drip groove 612. Since the exhaust groove 614 can exhaust, the detection liquid will flow toward the end close to the exhaust groove 614. In this way, the detection liquid is easy to fully contact with each area block. Fig.28 The diagram shows a flow state in which the detection liquid flows into the installation groove 617 along the flow channel 613 after the detection liquid is dripped into the drip groove 612 .

[0104] It is understandable that the detector is not limited to the use of color detectors. Depending on the type of test fluid to be detected or the indicator to be detected, at least one detector shown includes a photoelectric detector, and the test fluid is analyzed by light information obtained by the photoelectric detector.

[0105] The drop detection device may further include a processor configured to process the detection information of the detector 714 to obtain and output the detection result. The processor may be connected to a display terminal (such as a mobile phone or a computer) to display the detection result on a real terminal for user viewing.

[0106] The following describes the use of a specific embodiment Figure 1-Figure 22 The urine testing device shown describes the process of testing urine.

[0107] First, the test paper storage 1 is placed into the box structure 21 of the installation body 2 , and the roller 21 of the test paper storage 1 is installed on the rotating shaft 32 in the box structure 21 .

[0108] The urine test is started, and the control device responds to the test instruction to determine whether the test paper assembly 6 at the target position of the drum 11 (the position corresponding to the pushing device 4) is an unused target test paper assembly. If the test paper assembly at the target position is an unused target test paper assembly, the control device controls the pushing motor 41 to drive the lead screw 42 to rotate, so that the movable frame 43 moves from the first position to the second position, thereby pushing the test paper assembly 6 from the target position of the drum 11 to the detection chamber 7 at the detection position. If the test paper assembly at the target position of the roller 11 is not an unused target test paper assembly, the drive motor 31 is controlled to operate, and the drive motor 31 drives the rotating shaft 32 to rotate, so that the roller 11 rotates. After the angle sensor 83 detects that the roller 11 rotates a predetermined angle, the controller controls the drive motor 31 to stop, so that the roller 11 stops rotating. At this time, one of the unused test paper assemblies 6 of the roller 11 is aligned with the axial opening 1212 below, that is, the target test paper assembly reaches the target position. At this time, the pushing groove 611 of the test paper assembly 6 rotates to cooperate with the pushing claw 44 of the pushing device 4, and the control device controls the pushing motor 41 to drive the screw 42 to rotate, and the movable frame 43 moves from the first position to the second position, thereby pushing the test paper assembly 6 from the roller 11 to the detection chamber 71.

[0109] The lifting motor 721 is controlled to drive the cam 722 to rotate, and the cam 722 pushes the lifting frame 723 to descend to a predetermined height position, at which the dropper 724 on the lifting frame 723 pierces the diaphragm layer 63 of the test paper assembly 6 corresponding to the drip groove 612, and drips urine into the drip groove 612, and the piercing exhaust component 725 on the lifting frame 723 pierces the diaphragm layer 63 corresponding to the exhaust groove 614. The dropper 724 can be connected to a urine collection device, and urine is provided to the dropper 724 through the urine collection device.

[0110] After the urine contacts the reaction layer 62 of the test paper assembly 6, the detector in the detection chamber 71 detects the reaction information of the test paper assembly 6 and sends the detection information to the processor. The processor processes the data and obtains the detection result, and then sends the detection result to the display end.

[0111] After the test paper assembly 6 is tested, the push motor 41 drives the lead screw 42 to rotate in the opposite direction, and the moving frame 43 returns from the second position to the first position, pushing the used test paper assembly 6 back to the drum 11.

[0112] After the multiple test paper assemblies 6 on the drum 11 have been used up, the test paper storage 1 can be taken out and a new test paper storage 1 can be installed on the installation body 2 .
