[0026] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings.

[0027] Please refer to Figure 1 , the present invention proposes a fecal and urine integrated sampling liquid path system, including a toilet 1, a selector 2, a sampling assembly 3, a negative pressure assembly 4, and an air pump assembly 5. The selector 2, the sampling assembly 3, the negative pressure assembly 4, and the air pump assembly 5 are all electrically connected to an external controller. The external controller is connected to the mains power supply. The sampling assembly 3, the negative pressure assembly 4, the air pump assembly 5, and the external controller can all be integrally installed in the empty space area on the back of the toilet 1. The urine pipeline 11 and the fecal liquid pipeline 12 of the toilet 1 are respectively connected and conducted to one end of the selector 2. The other end of the selector 2 is connected and conducted to one end of the sampling assembly 3. The negative pressure assembly 4 and the air pump assembly 5 are both connected and conducted to the other end of the sampling assembly 3. The selector 2 is used to select the urine pipeline 11 or the fecal liquid pipeline 12 to be conducted with the sampling assembly 3 to separately sample urine or fecal liquid.

[0028] In this embodiment, the selector 2 selectively connects the urine pipeline 11 and the fecal liquid pipeline 12 of the toilet to the sampling assembly 3 to facilitate separate sampling of urine or fecal liquid. When the user needs to take a sample, the user can select to obtain urine or fecal liquid on the external controller. After selecting urine, when sampling urine, the selector 2 connects the urine pipeline to the sampling assembly 3, and the negative pressure assembly 4 is turned on, so that the sampling assembly 3 generates negative pressure to separately obtain a urine sample. After selecting fecal liquid, when sampling fecal liquid, the selector 2 connects the fecal liquid pipeline 12 to the sampling assembly 3, and the air pumping assembly 5 is turned on to inject air into the toilet to stir the feces by blowing. After the feces are stirred, the negative pressure assembly 4 is turned on, so that the sampling assembly 3 generates negative pressure to separately obtain a fecal liquid sample;

[0029] In summary, the integrated fecal and urine sampling liquid path system can selectively obtain fecal liquid or urine to improve the function of sample acquisition and facilitate the user's detection.

[0030] In this embodiment, the selector 2 is provided with a first access port 21, and the first access port 21 is connected and communicated with the urine pipeline 11. The selector 2 is provided with a second access port 22, and the second access port 22 is connected and communicated with the fecal liquid pipeline 12. When sampling urine, the selector 2 opens the first access port 21, so that the urine in the urine pipeline 11 enters the sampling assembly 3 from the first access port 21 to obtain urine. When sampling fecal liquid, the selector 2 opens the second access port 22, so that the fecal liquid in the fecal liquid pipeline 12 enters the sampling assembly 3 from the second access port 22 to obtain fecal liquid.

[0031] In this embodiment, the sampling assembly 3 includes a buffer bottle 31, a sampling module 32, and a liquid extraction valve 33. One end of the buffer bottle 31 is connected and communicated with the negative pressure assembly 4 and the air pumping assembly 5. The other end of the buffer bottle 31 is connected and communicated with one end of the sampling module 32. The other end of the sampling module 32 is connected and communicated with one end of the liquid extraction valve 33. The other end of the liquid extraction valve 33 is connected and communicated with one end of the selector 2. The buffer bottle 31 is used to store the obtained liquid sample, so as to screen out the most suitable liquid sample for detection and flow it into the sampling module 32. The specific sampling method is as follows: when obtaining urine, the negative pressure assembly 4 is turned on, and a negative pressure is formed in the buffer bottle 31. Since the buffer bottle 31 is communicated with the sampling module 32, a negative pressure is also formed in the sampling module 32. After the liquid extraction valve 33 is opened and conducted, the urine first enters the sampling module 32 from the liquid extraction valve 33, and then enters the buffer bottle 31 when the sampling module 32 is full. In order to improve the detection accuracy of urine, usually the middle section of the whole urine is taken for detection. That is, the function of the buffer bottle 31 is to store the urine in the front section, so that the middle section of the urine is retained in the sampling module 32. When obtaining fecal fluid, it is the same as the method of obtaining urine above. The buffer bottle 31 is also required to store the first half of the fecal fluid, so that the fecal fluid retained in the sampling module 32 has a balanced concentration.

[0032] In this embodiment, the sampling module 32 includes a liquid accumulation bottle 321, a sampling needle 322, and a pump plunger 323. One side of the liquid accumulation bottle 321 is connected and communicated with the buffer bottle 31. The other side of the liquid accumulation bottle 321 is connected and communicated with the liquid extraction valve 33. The sampling needle 322 is inserted into the liquid accumulation bottle 321 and is communicated with the liquid accumulation bottle 321. One end of the sampling needle 322 is connected and communicated with one end of the pump plunger 323. When sampling a sample, the liquid sample is stored in the liquid accumulation bottle 321. The pump plunger 323 is started to transmit the negative pressure into the sampling needle 322, and the sampling needle 322 samples the liquid in the liquid accumulation bottle 321.

[0033] In this embodiment, the sampling assembly 32 further includes a liquid level sensor 34. The liquid level sensor 34 is used to detect the liquid level height in the buffer bottle 31. When the liquid level in the buffer bottle 31 rises to a preset height, the liquid level sensor 34 sends a signal to the external controller, and the external controller issues a stop operation instruction to the negative pressure assembly 4, and the negative pressure assembly 4 stops operating, and the buffer bottle 31 no longer sucks liquid.

[0034] In this embodiment, the negative pressure assembly 4 includes a vacuum pump 41 and a vacuum valve 42. The vacuum pump 41 is connected and communicated with one end of the vacuum valve 42. The other end of the vacuum valve 42 is connected and communicated with the sampling assembly 3. Specifically, the other end of the vacuum valve 42 is connected and communicated with the buffer bottle 31. When sampling a liquid sample, the vacuum pump 41 is turned on. After the vacuum valve 42 is opened, the negative pressure is transmitted into the buffer bottle 31, and then the buffer bottle 31 starts to suck the liquid sample.

[0035] In this embodiment, the air pumping assembly 5 includes an air pump 51 and an air valve 52. One end of the air pump 51 is connected to and communicated with one end of the air valve 52, and the other end of the air valve 52 is connected to and communicated with the sampling assembly 3. When sampling fecal liquid, since the fecal concentration in the water is not balanced during the soaking process of feces, it is necessary to stir the fecal liquid here to ensure that the fecal concentration in the obtained fecal liquid is balanced. For the sake of simplicity in stirring, the blowing method is adopted for stirring. During stirring, the air valve 52 is opened and the air pump 51 is turned on, and the air flow enters the fecal liquid to be turbulent, so as to stir the fecal liquid. After the fecal liquid is stirred for a preset time, the fecal liquid can be sampled, and the sampling process is the same as the operation process of the negative pressure assembly 4 described above.

[0036] In this embodiment, the feces and urine integrated sampling liquid path system further includes a flushing and cleaning assembly 6. One end of the flushing and cleaning assembly 6 is connected to and communicated with the sampling module 32, and the other end of the flushing and cleaning assembly 6 is connected to and communicated with the buffer bottle 31. The flushing and cleaning assembly 6 is electrically connected to an external controller. To ensure the cleanliness of the sampling assembly 3, the selector 2 and the pipelines connected thereto, that is, there should be no residual fecal liquid during urine sampling and no residual urine during fecal liquid sampling. After each sampling, it is necessary to use the flushing and cleaning assembly 6 for reverse cleaning. After one sampling, the external controller will automatically start the flushing and cleaning assembly 6 to ensure that the user will not be contaminated by the previous sampling during the next liquid sampling.

[0037] In this embodiment, the flushing and cleaning assembly 6 includes a toilet constant pressure water pump 61, a water inlet valve 62, and a cleaning valve 63. The toilet constant pressure water pump 61 is respectively connected and communicated with one end of the water inlet valve 62 and one end of the cleaning valve 63. The other end of the water inlet valve 62 is connected and communicated with the buffer bottle 31, and the other end of the cleaning valve 63 is connected and communicated with the sampling module 32. The toilet constant pressure water pump 61 is connected to the water tank of the toilet. When the flushing and cleaning assembly 6 performs reverse flushing, the buffer bottle 31 and the sampling module 32 are flushed. When flushing, the toilet constant pressure water pump 61 is turned on. After the water inlet valve 62 is turned on, the buffer bottle 31 is flushed. After the cleaning valve 63 is turned on, the liquid accumulation bottle 321, the sampling needle 322, and the pump plunger 323 are flushed together. During this flushing process, the first access port 21, the second access port 22, and the liquid extraction valve 33 of the selector 2 all need to be turned on together, so that the flushing liquid directly flows into the toilet 1. After flushing, the toilet constant pressure water pump 61, the water inlet valve 62, and the cleaning valve 63 are all turned off. The pump air assembly 5 pumps gas into the buffer bottle 31, so that the gas discharges the excess flushing liquid into the toilet 1. Then, the first access port 21, the second access port 22, and the liquid extraction valve 33 of the selector 2 are closed. At this time, the reverse flushing process is completed, keeping the pipeline clean. At the same time, the gas discharges the excess flushing liquid into the toilet, achieving a drying effect on the overall liquid pipeline.

[0038] Certainly, the present utility model can also have many other embodiments. Based on this embodiment, other embodiments obtained by those of ordinary skill in the art without any creative work belong to the scope protected by the present utility model.
