[0071] like Figure 1-Figure 3As shown, this embodiment provides a urine detector, which includes a housing component 1, a circuit board 2, an illumination component 3, a collection component 4 and a microprocessor chip component 5. Specifically, a liquid inlet channel 121 and a detection channel 122 connected to the liquid inlet channel 121 are provided in the housing component 1, and a dry sheet reagent is provided in the detection channel 122, and the detection liquid can move to the dry sheet reagent in the detection channel 122 through the liquid inlet channel 121; the circuit board 2 is installed in the housing component 1 and is located on one side of the detection channel 122; the illumination component 3 is arranged on the side of the circuit board 2 close to the detection channel 122, and the illumination component 3 is used to irradiate the dry sheet reagent in the detection channel 122; the collection component 4 is provided with a light intensity detection sensor 41, and the light intensity detection sensor 41 is used to collect reflected light on the dry sheet reagent; the microprocessor chip component 5 is arranged on the circuit board 2 and is electrically connected to the collection component 4; the indication component 6 includes a warning light 61, and the warning light 61 is electrically connected to the microprocessor chip component 5, and the warning light 61 is used to indicate the detection result of the detection liquid in the corresponding detection channel 122.

[0072] When the urine detector is used to detect urine, the detection liquid is urine, and the urine detector is placed in the detection liquid; the detection liquid can move to the dry sheet reagent in the detection channel 122 through the liquid inlet channel 121, and the substance to be detected in the urine reacts with the dry sheet reagent and causes the dry sheet reagent to change color, and the depth of the color is proportional to the concentration of the substance to be detected in the urine sample; the dry sheet reagent is irradiated by the illumination component 3 and generates different reflected light, and the light intensity detection sensor 41 receives the optical signal of the reflected light and converts it into a corresponding electrical signal, and then calculates the reflectivity of the substance to be detected in the urine through the microprocessor chip component 5, and then deduces the concentration of the substance to be detected based on the reflectivity, and compares whether the concentration is within the interval, and finally prompts a positive or negative result in the form of a warning light 61. The urine tester is small and portable, disposable, and does not require an integrated device design. It solves the pain point that existing routine urine tests require a combination of urine analyzer, routine urine reagents and mobile phone software, mini-programs or laboratory information systems to complete the test, or that the visual method has large differences. The warning light 61 can be used to intuitively understand the concentration status of the substance to be tested in the urine, thereby improving the detection accuracy.

[0073] In the prior art, conventional urine detectors can only analyze a single component in urine during each detection process. Preferably, the detection channels 122, dry sheet reagents, light intensity detection sensors 41, and warning lights 61 are multiple and correspond one to one, and multiple detection channels 122 are connected to the liquid inlet channel 121. The urine detector is provided with multiple detection channels 122, and the dry sheet reagents in the detection channels 122 can be set to different types according to the types of different substances to be detected in the detection liquid. When the urine detector is used to detect urine, the detection liquid is urine, and the urine detector is placed in the detection liquid; the detection liquid can move to the dry sheet reagent in the detection channel 122 through the liquid inlet channel 121, and different substances to be detected in the urine react with different types of dry sheet reagents and cause the dry sheet reagent to change color, and the depth of the color is proportional to the concentration of the substance to be detected in the urine sample; each dry sheet reagent is irradiated by the illumination component 3 and produces different reflected light, and the light intensity detection sensor 41 receives light signals of different intensities and converts them into corresponding electrical signals, and then calculates the reflectivity of each substance to be detected in the urine through the microprocessor chip component 5, and then derives the concentration of the substance to be detected from the reflectivity, and compares whether the concentration is within the interval. Through the urine detector, a single detection is achieved to complete the detection of multiple substances to be detected in urine, improve the detection efficiency, reduce the detection error, and improve the detection accuracy. In this embodiment, the light intensity detection sensor 41 is a monochrome sensor, which corresponds to the change color of the dry sheet reagent and can collect the reflectivity of the change color of the dry sheet reagent.

[0074] Preferably, the detection channel 122, the liquid inlet channel 121, the dry sheet reagent, and the light intensity detection sensor 41 are all multiple and correspond one to one, and multiple light intensity detection sensors 41 correspond to one microprocessor chip assembly 5. Since multiple light intensity detection sensors 41 correspond to one microprocessor chip assembly 5, the data of multiple light intensity detection sensors 41 are processed by one microprocessor chip assembly 5, which reduces the number of microprocessor chip assemblies 5, thereby reducing the production cost of the urine detector.

[0075] In this embodiment, the housing assembly 1 includes an upper housing 11 and a lower housing 12 connected to each other, a liquid inlet channel 121 and a detection channel 122 are arranged on the lower housing 12, and a circuit board 2 is installed on the side of the upper housing 11 facing the lower housing 12. Among them, the material of the upper housing 11 and the lower housing 12 can be a degradable material such as polylactic acid plastic, polybutylene succinate, polycaprolactone or polyhydroxyalkanoate, which is convenient for disposable use. After the urine detector is used, it can be directly flushed into the sewer. The upper housing 11 and the lower housing 12 can be connected by snap-fitting, and the circuit board 2 reserves 4 circular holes for fixing with the connecting rod in the upper housing 11; a chromatography guide plate can also be arranged on the lower housing 12, and the detection channel 122 is arranged on the chromatography guide plate, and the light intensity detection sensor 41 is located directly above the dry film reagent. Preferably, the upper shell 11 and the lower shell 12 are both hemispherical, and the multiple liquid inlet channels 121 are located in the central area of ​​the lower shell 12 on the side facing the upper shell 11, and the multiple detection channels 122 extend radially from the central area away from the liquid inlet channels 121.

[0076] Preferably, there are eight detection channels 122, and there are eight detection channels 122, eight liquid inlet channels 121, and eight light intensity detection sensors 41, and they correspond one to one. In other embodiments, there are two, four, or six detection channels 122. Figure 4 As shown, when there are four detection channels 122, the four detection channels 122 are arranged in a cross shape on one side of the lower housing 12 facing the upper housing 11, and the four liquid inlet channels 121 are located in the center area of ​​the cross. The liquid inlet channels 121 extend vertically to the bottom of the urine detector.

[0077] Preferably, if Figure 1-Figure 3 As shown, the warning light 61 can light up red and green. Among them, when the concentration of the substance to be detected in the detection liquid is not within the standard concentration range, the warning light 61 lights up red; when the concentration of the substance to be detected in the detection liquid is within the standard concentration range, the warning light 61 lights up green; when the concentration detection of the substance to be detected in the detection liquid fails, the warning light 61 does not light up. In this embodiment, the detection result can be obtained by visual inspection, the operation is simple, and the application range is wide. In this embodiment, there are eight warning lights 61, and the eight warning lights 61 are respectively used to indicate the detection results of the corresponding substances to be detected in the eight detection channels 122.

[0078] Furthermore, a plurality of warning lights 61 are mounted on a side of the circuit board 2 away from the detection channel 122, and the housing assembly 1 is provided with a light-through hole 111, through which the light of the warning lights 61 can pass. In this embodiment, the light-through hole is located on the top surface of the upper housing 11, and the light of the warning lights 61 is emitted through the light-through hole 111, which is convenient for users to observe.

[0079] Furthermore, in this embodiment, the illumination assembly 3 includes a plurality of LED light sources 31, and the plurality of LED light sources 31 correspond one to one with the plurality of light intensity detection sensors 41, and the LED light sources 31 are arranged on the circuit board 2 and are located on one side of the light intensity detection sensor 41. The LED light sources 31 arranged in this way are closer to the dry sheet reagent, which improves the brightness of the dry sheet reagent and facilitates the light intensity detection sensor 41 to collect the reflected light of the dry sheet reagent.

[0080] In other embodiments, the illumination assembly 3 includes an LED light source 31, which is located above one end of the plurality of detection channels 122 connected to the liquid inlet channel 121. The LED light source 31 can illuminate the dry slide reagents in the plurality of detection channels 122, thereby reducing material costs.

[0081] In the prior art, dry test strips are usually directly immersed in urine, and then the color change of the dry test strips is observed; however, urine contains some formed components such as crystals, casts, and mucus, which will affect the color judgment of the reagent. In order to solve the above problems, the urine detector also includes multiple chromatographic components 9, multiple chromatographic components 9, multiple detection channels 122 and multiple liquid inlet channels 121 correspond one to one, and the chromatographic component 9 is attached to the detection channel 122 and the liquid inlet channel 121. The end of the chromatographic component 9 located in the detection channel 122 is provided with a dry reagent, and the end of the chromatographic component 9 located in the liquid inlet channel 121 can adsorb the detection liquid. When in use, the urine sample is drained to the fixed dry reagent through the liquid inlet channel 121 and the detection channel 122 containing the chromatographic component 9; the chromatographic component 9 can effectively intercept some formed components containing crystals, casts, and mucus in urine, avoid the influence on the color judgment of the dry reagent, and improve the detection accuracy. In this embodiment, the chromatography element 9 is spread evenly throughout the detection channel 122 , and the dry sheet reagent is adhered to the top of the chromatography element 9 by adhesive.

[0082] Preferably, the chromatography element 9 can be a chromatography column or chromatography paper. In this embodiment, the chromatography element 9 is chromatography paper.

[0083] In this embodiment, a liquid collecting port 123 is provided at the liquid inlet end of the liquid inlet channel 121, and one end of the chromatography element 9 located in the liquid inlet channel 121 blocks the liquid collecting port 123. In this embodiment, the light intensity detection sensor 41 only needs a small amount of urine to meet the requirements of the analysis and detection. By blocking the liquid collecting port 123 with the chromatography element 9, the detection liquid can only be drained through the chromatography element 9, preventing the detection liquid from entering the urine detector in excessive amounts, causing water ingress and damage to the circuit board 2. In this embodiment, the liquid collecting port 123 includes a plurality of small holes.

[0084] Furthermore, a counterweight 13 is provided at the bottom of the lower shell 12. The counterweight 13 is used to make the urine detector float on the test liquid, and the liquid inlet end of the liquid inlet channel 121 is located at the bottom.

[0085] In this embodiment, the urine detector further includes a plug switch 8, which is electrically connected to the circuit board 2. The plug of the plug switch 8 extends out of the upper housing 11. When the plug is unplugged, the urine detector starts to work.

[0086] like Figure 1-Figure 5 As shown, this embodiment also provides a method for using a urine detector, which is applied to the above-mentioned urine detector. The method for using the urine detector includes the following steps:

[0087] S11, collecting the test liquid into a collection cup; wherein, when the test liquid is urine, the urine is collected into the collection cup;

[0088] S12, after activating the urine detector, place it in the collection cup, and the detection liquid moves to the dry sheet reagent in the detection channel 122 through the liquid inlet channel 121; in this embodiment, press the switch of the urine detector, activate the urine detector and place it in the urine cup, at this time, the liquid collection port 123 is located directly below the urine detector; urine is connected to the chromatography element 9 through the liquid collection port 123; the urine is drained to the position of the dry sheet reagent through the chromatography element 9, and at this time, the substance to be detected in the urine will react with the dry sheet reagent to produce a color change;

[0089] S13, the microprocessor chip assembly 5 is set to activate the urine detector for a first preset time and then turn on the illumination assembly 3, and the light intensity detection sensor 41 continues to receive the light signal of the reflected light of the dry sheet reagent within a second preset time; in this embodiment, the first preset time is 1 minute and the second preset time is 5 seconds;

[0090] S14, the microprocessor chip assembly 5 converts the optical signal of the reflected light into an electrical signal, calculates the reflectivity according to the electrical signal, and calculates the concentration of the substance to be detected in the detection liquid according to the reflectivity;

[0091] S15, comparing the concentration of the substance to be detected with the standard concentration, and finally indicating a positive or negative result by means of a warning light 61.

[0092] Furthermore, in step S15, if the warning light 61 is green, it is judged that the concentration of the substance to be detected in the test liquid meets the requirements; if the warning light 61 is red, it is judged that the concentration of the substance to be detected in the test liquid does not meet the requirements; if the warning light 61 is not on, it is judged that the urine tester has not performed the detection of the concentration of the substance to be detected in the test liquid.

[0093] It should be noted that the microprocessor chip assembly 5 converts the optical signal into an electrical signal, calculates the reflectivity based on the electrical signal, and calculates the concentration of the substance to be detected in the detection liquid based on the reflectivity. This is a prior art and the specific principle will not be repeated here.

[0094] The existing products not only have complicated operation processes, but also have expensive instruments and require maintenance. The urine detector is convenient for users to perform automatic urine tests when using the toilet, and can provide early warnings of personal physical conditions. The chromatography element 9 can ensure that the sample and the dry film reagent fully react, and can filter out the influence of the formed components in the urine on color recognition, thereby ensuring the accuracy of the test results of the sample component determination device; the light intensity detection sensor 41 and the dry film reagent are specially matched, which not only improves the sensitivity of the detection, but also greatly reduces the cost of materials, and has the basic conditions for disposable detection products. The rectangular detection channel 122 can form a dark room between the light intensity detection sensor 41 to avoid the influence of stray light, thereby reducing the volume of the detection liquid, and only a small amount of sample is needed to obtain the result.

[0095] Embodiment 2

[0096] This embodiment also provides a urine detector. The structure of the urine detector provided in this embodiment is basically the same as that of the first embodiment, with only some structural differences. This embodiment will not repeat the structure that is the same as that of the first embodiment.

[0097] In this embodiment, Figure 6-Figure 9 As shown, there are multiple detection channels 122, liquid inlet channels 121, dry film reagents and warning lights 61 and they correspond one to one.

[0098] The urine detector is provided with a plurality of detection channels 122, and the dry sheet reagents in the detection channel 122 can be set to different types according to the types of different substances to be detected in the detection liquid. When the urine detector is used to detect urine, the detection liquid is urine, and the urine detector is placed in the detection liquid; the detection liquid can move to the dry sheet reagent in the detection channel 122 through the liquid inlet channel 121, and different substances to be detected in the urine react with different types of dry sheet reagents and cause the dry sheet reagent to change color, and the depth of the color is proportional to the concentration of the substance to be detected in the urine sample; each dry sheet reagent is irradiated by the LED light source 31 and generates reflected light of different colors, and the light intensity detection sensor 41 receives the light signal of the reflected light and converts it into a corresponding electrical signal, and then calculates the reflectivity of each substance to be detected in the urine through the microprocessor chip component 5 on the circuit board 2, and then derives the concentration of the substance to be detected from the reflectivity, and compares whether the concentration is within the interval, so as to realize the detection of the concentration of the substance to be detected in the detection liquid on the dry sheet reagent. In this embodiment, the LED light source 31 emits white light, different dry sheet reagents produce different colors, and the light intensity detection sensor 41 can collect the light intensity of the reflected light of the changed color of the dry sheet reagent. In this embodiment, since the driving component 7 can drive the circuit board 2 to rotate, the concentration of the substance to be detected in the detection liquid on all dry sheet reagents is detected by a group of LED light sources 31 and light intensity detection sensors 41, which simplifies the product structure and reduces the production cost of the urine detector. Through the urine detector, a single test is achieved to complete the detection of multiple substances to be detected in urine, improve the detection efficiency, reduce the detection error, and improve the detection accuracy.

After the upper shell 11 and the lower shell 12 are assembled, there is a small gap between the end face of the crimping column 112 and the circuit board 2, which can prevent the circuit board 2 from detaching from the boss 125 and improve the structural stability, and on the other hand, the crimping column 112 has no contact with the circuit board 2 to prevent the circuit board 2 from being affected in its rotation.

At this time, the urine detector is easy to rotate, which affects the detection accuracy. Preferably, the outer wall of the housing component 1 is provided with a plurality of clamping posts 127 at intervals along the circumferential direction, and the clamping posts 127 are used to be embedded in the clamping groove of the urine cup.

According to the number of pre-installed dry sheet reagents and the angle arrangement relationship, the light intensity data corresponding to the number of dry sheet reagents is screened out, wherein, when the circuit board 2 rotates for the second time, the light intensity detection sensor 41 and the LED light source 31 rotate to the corresponding dry sheet reagent and stay for the fourth preset time, and the light intensity data of each group of dry sheet reagents is averaged to obtain the light intensity data of the dry sheet reagent at each position, so as to improve the detection accuracy, wherein the fourth preset time can be 5 seconds.
