The housing 301 is provided with a second cover 321 covering the two light emitting holes 304, and the positions of the second cover 321 corresponding to the two light emitting holes 304 are respectively provided with a light source 322. In this embodiment, the light source 322 is preferably a light source capable of emitting light of three different wavelengths. Of course, the wavelength of the light source 322 is selected according to the color of the reagent block 606, so that in different embodiments, the light source capable of emitting light with two different wavelengths, or the light source capable of emitting light with four or more different wavelengths, may be selected according to actual requirements. Of course, the light source 322 is further electrically connected to a light source driving circuit, and the photo-electric receiver 312 is further electrically connected to a photo-current detecting circuit, which are all the prior art and are not described herein again.
Certainly, the body fluid detection system is also electrically connected with a controller (not shown in the figure), and the pushing unit 500, the liquid injection unit 200 and the body fluid detection unit 300 are all electrically connected with the controller, so that the controller controls the units to complete liquid injection and detection.
In this embodiment, the liquid injection unit 200 with the perforating needle 202 and the liquid injection needle 201 is arranged to inject liquid into the detection card 600 covered with the protection film, and the perforating needle 202 and the liquid injection needle 201 punch the protection film at the same time, so that the length of the detection system can be greatly shortened, and the occupied volume can be reduced; by detecting the reagent block 606 by using the light reflection principle, compared with the method of judging the color of the reagent block 606 by using an image recognition method, the data amount to be uploaded to a server can be greatly reduced, and the color of the reagent block 606 does not need to be recognized.
The invention also discloses a health intelligent detection closestool which is provided with the body fluid detection system with the protective film detection card, so that urine or excrement collection fluid is detected by the body fluid detection system with the protective film detection card. Of course, the intelligent health detection toilet is further provided with a urine collection device and/or a stool collection device and other devices, and the collection channel of the urine collection device and/or the stool collection device is communicated with the liquid injection needle 201.
The following describes a specific working principle of the intelligent health detection toilet in this embodiment by taking a urine detection process as an example:
as shown in fig. 1 to 9, after the urine collecting device of the intelligent health detection toilet collects urine, the controller issues a detection instruction to enable the first motor 501 to drive the conveyor belt 504 to rotate, the pushing block 506 on the conveyor belt 504 starts to move from an initial position, enters the detection card accommodating box 400 through the notch 401, pushes the detection card 600 at the lowest end of the detection card accommodating box 400 out of the outlet into the chute 104, and controls the step distance of the first motor 501 to enable the detection card 600 to move to the liquid injection position and then stop moving; then, the controller causes the second motor 207 to bring the slider 204 to move downwards, causes the liquid injection needle 201 and the perforating needle 202 to pierce the protective film of the detection card 600, and causes the urine collecting device to inject the collected urine into the first exhaust hole 601 through the liquid injection needle 201, at this time, air in the air passage of the detection card 600 can be discharged through the hollow perforating needle 202 through the second exhaust hole 602 and the cavity between the front surface of the detection card 600 and the protective film, so that the injection of the urine is not affected. After entering the air passage, urine enters each reagent groove 603 through a liquid passing through hole 604 between the air passage and the reagent groove 603, and reacts with the reagent block 606 to change the color of the reagent block 606, namely, change the reflection intensity of the reagent block 606 to light with a specific wavelength.
Then, the second motor 207 drives the slider 204 to move upward, so that the injection needle 201 and the punching needle 202 are drawn out from the protective film and separated from the detection card 600 by a certain distance, then the first motor 501 drives the conveying belt 504 to rotate, so that the pushing block 506 pushes the detection card 600 to the first detection position and stops moving, at this time, the two reagent slots 603 in the first row (i.e. the two reagent slots adjacent to the first exhaust hole) are respectively located right below the two detection holes 302, light emitted by the two light sources 322 is respectively irradiated on the reagent blocks 606 in the two reagent slots 603 in the first row, and is respectively received by the two photoelectric receivers 312 after being reflected by the reagent blocks 606. As shown in fig. 10, the light emitted from the light source 322 is reflected diffusely by the surface of the reagent block 606 and then received by the photoelectric receiver 312. Due to the different colors of reagent patches 606, the proportion of light of a particular wavelength that they absorb is different, i.e., the intensity of reflection of light of a particular wavelength is different. Therefore, the intensity of light received by the photoelectric receiver 312 can be used as a basis for determining the value of the health index by knowing the reflection intensity of the reagent block 606 with respect to light of various wavelengths among the light emitted from the light source 322. For example, in the present embodiment, a light source capable of emitting light with three different wavelengths (i.e., a three-color light source) is adopted, the three-color light source sequentially emits light with three wavelengths, the photoelectric receiver 312 converts the light reflected by the reagent block 606 into a photocurrent, the reflection intensity of the reagent block 606 for the light with the wavelength can be known according to the magnitude of the photocurrent, and the weaker the received light intensity is, the more the light is absorbed by the reagent block 606, so that the reflection intensity of the light can be directly used to replace the absorption rate of the reagent block 606 for the light as the basis for determining the health index. In this embodiment, it is preferable that, for each reagent block 606, one light whose reflection intensity is in a linear relationship with a color that may be generated by the reagent block 606 and one light whose reflection intensity is in an exponential relationship with the color that may be generated by the reagent block 606 are respectively selected, the reflection intensities of the two lights are uploaded to a server as determination parameters of health indicators, and the reflection intensities of the other lights are discarded; of course, it is also possible to irradiate only two wavelengths of light required for each reagent patch 606, and not to irradiate each light, so as to shorten the detection time, but this will increase the complexity of control. The server calculates the ratio of the two lights, and obtains the contrast relationship between the ratio of the lights and the value of the health index according to the corresponding relationship between the ratio of the lights and the color and the corresponding relationship between the color and the health index, so that the color of the reagent block 606 does not need to be judged, and the corresponding value of the health index can be directly obtained according to the ratio of the lights.
After the detection of the reagent blocks 606 in the two reagent grooves 603 in the first row is completed, the first motor 501 continues to drive the conveyor belt 504 to rotate, so that the pushing block 506 pushes the detection card 600 to the second detection position and then stops moving, so that the two reagent grooves 603 in the second row are located right below the two detection holes 302, the detection process is repeated to detect the reagent blocks 606 in the two reagent grooves 603 in the second row, and then the reagent blocks 606 in the two reagent grooves 603 from the third row to the last row are sequentially detected, so that the detection of all the reagent blocks 606 in the detection card 600 is completed, and then the reflection values of the reagent blocks 606 on the light rays with the specific wavelength are uploaded to the server through the communication module, and the server can calculate the reflection ratio according to the reflection values of the reagent blocks 606 on the light rays with the specific wavelength after the reaction with urine, so as to obtain a urine detection result.
After the detection of the last detection position is completed, the pushing block 506 pushes the detection card 600 to the front end of the sliding chute 104, the abdicating through hole 507 of the conveying belt 504 is positioned under the liquid injection needle 201, then the second motor 207 drives the sliding block 204 to move downwards, the liquid injection needle 201 is inserted into the cleaning box 220 through the cleaning hole 221, and the liquid injection needle 201 is cleaned by the water discharged from the urine collecting device, because the liquid injection needle 201 is inserted into the cleaning box 220, the water does not spill out of the cleaning box 220 during cleaning, and only flows into the cavity of the cleaning box 220 and flows out through the water outlet pipe 222. After the cleaning is completed, the second motor 207 drives the sliding block 204 to move upward to a position before moving downward, and waits for the next detection.
Then, the first motor 501 continues to drive the conveyor belt 504 to rotate, so that the pushing block 506 is separated from the detection card 600, the pushing block 506 continues to move to the initial position, and after the first detector 505 detects the detection card 600, the controller stops the rotation of the first motor 501 and clears the step distance of the motor in the first step, so that error accumulation can be avoided. At this time, most of the test card 600 extends out of the chute 104, so that the user can take the test card 600 out of the chute 104. Meanwhile, the controller detects the detection card 600 through the fourth detector, if the user does not take out the detection card 600 within a preset time, the controller can control the loudspeaker to send out reminding information to remind the user to take the detection card 600 away, and if the user does not take the detection card 600 away, the next detection card 600 can push out the previous detection card 600 from the sliding groove 104 during the next detection, and the next detection cannot be influenced.
The intelligent detection closestool can adopt the detection card 600 covered with the protection film for detection, and the punching needle 202 and the liquid injection needle 201 punch the protection film at the same time, so that the length of the detection system can be greatly shortened, the occupied volume is reduced, and the detection system can be conveniently installed in the intelligent detection closestool; by detecting the reagent block 606 by adopting the light reflection principle, the color of the reagent block 606 does not need to be recognized, and the judgment of the health index is more convenient, so that the overhead of a server can be reduced.
Finally, the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it will be understood by those skilled in the art that modifications or equivalent substitutions may be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the claims of the present invention.
