Description

Technical Field

[0001] The utility model generally relates to the technical field of sanitary equipment, and more specifically, to a detection device and a smart toilet. Background Art

[0002] Urine contains many human metabolites and other active substances. Through routine urine tests, the health status of the human body can be effectively reflected. In a normal urine test process, urine needs to be received first, then the urine is dipped on a test strip, and finally the test is carried out. The whole process requires manual operation, which is inconvenient, and the test sample is easily contaminated, affecting the test results.

[0003] In recent years, with the development and progress of technology, it has been realized to integrate a urine detection device into a toilet. Users only need to urinate in the toilet, and the routine urine test can be automatically achieved, which is convenient and fast.

[0004] The urine detection device generally includes a test strip and a detection component for detecting and analyzing the test strip. The test strip reacts with the biochemical components in the urine to produce a color change. Based on the Lambert-Beer law, the detection component determines the color depth of the test strip according to the amount of emitted light reflected by the test strip, so as to measure the content of the biochemical components in the urine. However, the emitted light and the reflected light of the above detection component are easily interfered, affecting the test results.

[0005] In addition, for the current detection device integrated in the toilet, since the urine detection device is integrated on the toilet and the toilet is installed in the bathroom, the urine detection device is in a high-temperature and high-humidity environment for a long time, which requires a high weather resistance for the urine detection device. Moreover, the high-temperature and high-humidity environment is likely to interfere with the detection accuracy of the urine detection device.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art.

However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, some technical features well-known in the art are not described to avoid confusion with the present utility model.

[0039] Please refer to Figure 1 and Figure 2 As shown in FIGS. and, an embodiment of the present disclosure provides a detection device 100 configured in a smart toilet, including a housing 10, a detection board 20, and a light-shielding member 30. The detection board 20 and the light-shielding member 30 are installed inside the housing 10. The detection board 20 is used to detect and analyze a test strip 40, and the test strip 40 can be, for example, a urine test strip. The light-shielding member 30 is used to separate the light-emitting path 201 and the light-incident path 202 of the detection board 20.

[0040] It should be noted that in other embodiments, the detection board 20 can also be used for other reagents that react with urine, and the present disclosure does not specifically limit this.

[0041] In this embodiment, the top of the housing 10 is open and has a mounting portion to facilitate the installation of the detection board 20 and the light-shielding member 30. The bottom surface of the housing 10 forms a light-emitting panel 11, and the test strip 40 is disposed outside the light-emitting panel 11. The light-emitting panel 11 is provided with a transparent area allowing light to pass through. The light emitted by the detection board 20 passes through the light-emitting panel 11 and irradiates the color block 41 of the test strip 40, and the reflected light of the test strip color block 41 passes through the light-emitting panel 11 and is received by the detection board 20.

[0042] In this embodiment, the detection board 20 includes a circuit board 23, a light emitter 21, and a light receiver 22. The light emitter 21 and the light receiver 22 are installed on one side of the circuit board 23 facing the light-emitting panel 11. The light emitter 21 is used to emit light of a certain wavelength, which can be, for example, an LED lamp bead, an LCD lamp bead, a deuterium lamp, a tungsten lamp, etc. The light receiver 22 is used to receive the reflected light, which can be, for example, a light receiving sensor, and convert the received light signal into a signal to measure the reflectivity of the test strip color block 41.

[0043] Further, the detection board 20 is fixed to the housing 10 through a locking member. For example, in one embodiment, the locking member includes a fixing post 13 and a screw 14. The fixing post 13 has an opening through which the screw passes, and a mating cavity is formed at the bottom thereof. A protruding screw post 12 is provided on the light-emitting panel 11 of the housing 10, and a threaded hole for threaded engagement with the screw 14 is formed in the screw post 12. The detection board 20 is provided with a positioning hole, and the screw post 12 passes through the positioning hole to limit the detection board 20. The fixing post 13 is connected to the side of the detection board 20 facing away from the light-shielding member 30, and the portion of the screw post 12 passing through the detection board 20 is restricted in the mating cavity of the fixing post 13. The screw 14 passes through the opening of the fixing post 13 and is locked in the threaded hole of the screw post 12. The screw 14 can be, for example, a metal screw. Through the above arrangement, it can be effectively ensured that the screw 14 has a sufficient number of tapped threads to ensure the stable and reliable connection structure of the detection board 20.

[0044] Please refer to Figure 3 , further, in one embodiment, a light-shielding layer 24 is provided on the side of the circuit board 23 of the detection board 20 facing the light-shielding member 30. The light-shielding layer 24 is located on the outer peripheral side of the light receiver 22, and / or the light-shielding layer 24 is located on the outer peripheral side of the light emitter 21. Specifically, the light-shielding layer 24 can be formed by coating an opaque coating on the surface of the circuit board 23, such as coating a black coating. In another embodiment, the light-shielding layer 24 can also be provided inside the substrate of the circuit board 23, for example, by covering a copper layer or an opaque material inside the circuit board 23 to form the light-shielding layer.

[0045] By providing the light-shielding layer 24, the phenomenon of light leakage during the process of emitting or receiving light can be further reduced, and the influence of ambient light on the detection result can be avoided, further improving the accuracy of the detection result.

[0046] It should be noted that the light-shielding layer 24 can be provided only on the outer peripheral side positions of the light emitter 21 and the light receiver 22. It can also be that the light-shielding layer 24 is provided on the entire circuit board 23, which simplifies the manufacturing process and improves the light-shielding effect.

[0047] In this embodiment, the light-shielding member 30 is disposed between the detection board 20 and the light-emitting panel 11 of the housing 10. The light-shielding member 30 is provided with independent light-emitting cavities 31 and light-incident cavities 32. The light emitter 21 is located in the light-emitting cavity 31, and the light receiver 22 is located in the light-incident cavity 32. The light-emitting panel 11 is transparently provided at positions corresponding to the light-emitting cavity 31 and the light-incident cavity 32. The light emitted by the light emitter 21 passes through the light-emitting cavity 31 and exits from the light-emitting panel 11 to the test strip color block 41, forming a light-emitting path 201. The light reflected by the test strip color block 41 passes through the light-emitting panel 11 and enters the light-incident cavity 32, and is received by the light receiver 22, forming a light-incident path 202.

[0048] Further, in one embodiment, the material of the housing 10 or the light-emitting panel 11 is a transparent material to ensure unobstructed light paths. That is, the entire housing 10 can be entirely transparent, or only the light-emitting panel 11 can be transparent.

[0049] Further, in one embodiment, the light-shielding member 30 is independently formed and fixedly installed in the installation portion of the housing. In one embodiment, the light-shielding member 30 can be configured as a detachable structure. For example, the light-shielding member 30 is clamped and fixed between the circuit board 23 and the light-emitting panel 11. Alternatively, the light-shielding member 30 is fixed to the housing by detachable connection methods such as snap connection. In other embodiments, the light-shielding member 30 can also be fixed by non-detachable methods such as welding and bonding.

[0050] Further, in one embodiment, the light-shielding member 30 is made of a light-impermeable material. For example, the light-shielding member 30 is configured to be black and light-impermeable to better ensure the light path separation effect. The light-shielding member 30 can be prepared from materials such as black ABS plastic. Further, the light-shielding member 30 is an integrally formed structure, which is easier to prepare and has a more stable structure.

[0051] Further, in other embodiments, it can also be that an opaque layer is formed on the surface of the light-shielding member 30 to achieve the light path separation effect. Specifically, in one embodiment, the opaque layer is formed by covering a coating or etching and blackening on the upper surface and / or the lower surface of the light-shielding member 30. For example, the coating is covered by methods such as applying black paint or screen printing ink. In another embodiment, the opaque layer is formed by chemically assisting the corrosion and blackening of the surface of the light-shielding member 30. For example, the surface of the light-shielding member 30 is corroded by reagents such as strong acids and strong alkalis, so that the surface of the light-shielding member 30 is blackened to form an opaque layer.

[0052] Please refer to Figure 4 and Figure 5 , in this embodiment, the aperture of the light-emitting cavity 31 at the end close to the detection board 20 is larger than the aperture at the end close to the light-emitting panel 11. That is, along the light-emitting path of the light emitter 21, the aperture of the light-emitting cavity 31 is larger at the top and smaller at the bottom. The farther away from the light source, the smaller the aperture of the light-emitting cavity 31, so as to facilitate the convergence of the emitted light and prevent the emitted light from entering positions outside the test strip color block 41, affecting the test results.

[0053] Further, in one embodiment, the light-emitting cavity 31 includes a connected light-emitting hole 311 and a light-condensing hole 312. The light-condensing hole 312 is disposed on the side close to the light-emitting panel 11, and on the connecting surface of the light-emitting hole 311 and the light-condensing hole 312, and the aperture of the light-condensing hole 312 is smaller than the aperture of the light-emitting hole 311.

[0054] Further, in one embodiment, along the light-emitting path of the light emitter 21, the aperture of the light-emitting hole 311 remains unchanged, and the aperture of the light-condensing hole 312 gradually decreases. With this setting, the emitted light can be better converged, improving the detection accuracy.

[0055] Further, along the light-emitting path of the light emitter 21, the length of the light-emitting hole 311 is greater than the length of the light-condensing hole 312 to further improve the converging effect of the emitted light.

[0056] It should be noted that, in other embodiments, the light-emitting cavity 31 can also be configured such that along the light-emitting path of the light emitter 21, the aperture of the light-emitting cavity 31 gradually decreases, and the light-converging effect is achieved through the gradually decreasing aperture.

[0057] Further, in one embodiment, along the light-emitting path of the light emitter 21, the aperture of the light-incident cavity 32 gradually decreases. By setting the light-incident cavity 32 to have a larger upper part and a smaller lower part, while ensuring the light flux for detection, other stray light is prevented from mixing into the light receiver 22.

[0058] Further, in one embodiment, the aperture of the light-emitting cavity 31 near the light-emitting panel 11 is smaller than the aperture of the light-incident cavity 32 near the light-emitting panel 11 to ensure that sufficient reflected light enters the light receiver 22.

[0059] Further, in one embodiment, one or more light emitters 21 and light receivers 22 are mounted on the detection board 20. The light emitters 21 and light receivers 22 are arranged in pairs to simultaneously detect multiple test paper color patches. One or more partition plates 33 are configured in the light-shielding member 30 to partition one or more light-emitting cavities 31 and light-incident cavities 32. The light-emitting cavities 31 and light-incident cavities 32 are also arranged in pairs and are adapted to the number of the light emitters 21 and light receivers 22.

[0060] Further, the interval between the paired light-emitting cavity 31 and light-incident cavity 32 is 0.1 - 5 mm, more preferably 0.1 - 2 mm. That is, the thickness of the partition plate 33 between the light-emitting cavity 31 and the light-incident cavity 32 is 0.1 - 2 mm. For example, it can be 0.2 mm, 0.4 mm, 0.6 mm, 1.2 mm, 1.8 mm, etc. Further, when multiple pairs of light-emitting cavities 31 and light-incident cavities 32 are provided, the interval between two adjacent light-emitting cavities 31 or two adjacent light-incident cavities 32 is 0.1 - 2 mm, more preferably 0.1 - 2 mm. That is, the thickness of the partition plate 33 between two adjacent light-emitting cavities 31 and between two adjacent light-incident cavities 32 is 0.1 - 2 mm. For example, it can be 0.2 mm, 0.4 mm, 0.6 mm, 1.2 mm, 1.8 mm, etc. By controlling the thickness of the partition plate 33, mutual interference of multiple emitted light beams or reflected light beams is effectively avoided, and the volume of the detection device 100 is minimized to adapt to the installation space inside the toilet.

[0061] Further, in one embodiment, a sealant layer is provided on the side of the detection plate 20 away from the light-emitting panel 11 to seal the detection plate 20 within the housing 10. For example, in one embodiment, after the detection plate 20 and the housing 10 are locked and fixed, a glue pouring operation is performed above the detection plate 20 to form a sealant layer above the detection plate 20, thereby simultaneously performing glue pouring protection on the detection plate 20 and the light-shielding member 30, avoiding the invasion of water vapor and the interference of high-temperature and high-humidity environments, effectively extending the service life of the detection device 100, and ensuring that the detection results are not interfered.

[0062] Please refer to Figure 6 , further, in one embodiment, an installation groove 101 is formed on the light-emitting panel 11, and the light-shielding member 30 is disposed within the installation groove 101. By providing the installation groove 101, the positions of the light emitter 21 and the light receiver 22 on the detection plate 20 can be better aligned to ensure the installation effect.

[0063] Further, the gap between the circumferential side of the light-shielding member 30 and the installation groove 101 is x, and the value range of x is: 0 - 0.5 mm, more preferably 0 - 0.1 mm. For example, when x is 0.1 mm, and the length and width of the light-shielding member 30 are a and b (in mm), respectively, then the length and width of the installation groove 101 are a + x and b + x (in mm), respectively. For example, the length and width of the installation groove 101 are (a + 0.1) mm and (b + 0.1) mm, respectively. Through the above design, a good fit between the light-shielding member 30 and the installation groove 101 is ensured.

[0064] Furthermore, a seal 34 is disposed between the circumferential side of the light-shielding member 30 and the mounting groove 101. Specifically, the seal 34 is configured as a sealing ring, and an annular groove adapted to the sealing ring is provided on the circumferential side of the light-shielding member 30. The seal 34 is used to seal the circumferential side of the light-shielding member 30 and the housing 10, preventing the glue from flowing to the light-emitting panel 11 during the glue injection process and affecting the detection effect.

[0065] Furthermore, in one embodiment, the gap between the upper end of the light-shielding member 30 and the detection plate 20 is 0 to 0.1 mm, and the gap between the lower end of the light-shielding member 30 and the light-emitting panel 11 is 0 to 0.1 mm. For example, both ends of the light-shielding member 30 are provided as flat surfaces, and its upper end abuts against the detection plate 20, and the lower end abuts against the light-emitting panel 11 to better ensure the light-emitting and light-incident effects.

[0066] This embodiment also provides an intelligent toilet, including a toilet body (not shown in the figure) and the above-described detection device 100. The detection device 100 can be disposed, for example, in the internal space of the toilet body. A urine test strip 40 is provided in the toilet body, and a plurality of color patches 41 can be provided on the urine test strip 40 to detect different biochemical components. A driving device for driving the urine test strip 40 to move can also be provided in the toilet body to extend the urine test strip to the toilet bowl for sampling. The specific installation structures of the driving device and the urine test strip can refer to the structures of existing urine test toilets and will not be described in detail herein.
