[0024] Figures 1 to 4 A schematic view of an apparatus for automatically collecting images of fecal samples, the apparatus for automatically collecting images of fecal samples is used to automatically collect a large number of scene-consistent high-definition images of feces 3, to provide a reliable and high-value training set for image analysis of the feces 3, to help improve the accuracy of algorithm analysis, and to reveal more information related to gastrointestinal diseases.

[0025] The apparatus for automatically collecting images of fecal samples includes a toilet 1 and a collection structure 2.

[0026] The toilet 1 is a common sitting toilet in a family or a squat toilet in a public place.

[0027] The collection structure 2 comprises a connecting pipe 21, an upper interface 22, a lower interface 23, a main control board 24, a baffle 25, a camera 26, a light source 27, a driving member 28 and a sensor 29.

[0028] The connecting pipe 21 comprises a flushing wall 210, a mounting wall 211 and a side wall 212. The flushing wall 210 is arranged obliquely to facilitate the water flow to flush away the excrement 3. The mounting wall 211 is parallel to the horizontal plane and is located at the highest position of the connecting pipe 21. The side wall 212 is connected with the mounting wall 211 and is perpendicular to the mounting wall 211. The side wall 212 is arranged opposite to the flushing wall 210, and the end of the flushing wall 210 and the end of the side wall 212 form a water flow channel.

[0029] The upper interface 22 is located at the end of the connecting pipe 21, and the upper interface 22 is connected with the flushing wall 210 and the mounting wall 211. The upper interface 22 is sealingly connected with the water outlet of the closestool 1.

[0030] The lower interface 23 is located at the other end of the connecting pipe 21, and the lower interface 23 is connected with the flushing wall 210 and the side wall 212. The lower interface 23 is sealingly connected with the sewage pipe.

[0031] The main control board 24 is installed outside the connecting pipe 21. The main control board 24 is electrically connected with the camera 26, the light source 27, the driving member 28 and the sensor 29. The main control board 24 receives the signal fed back by the sensor 29, and controls the camera 26, the light source 27 and the driving member 28 to work according to the signal fed back by the sensor 29. The main control board 24 has image storage and export functions, and has reliable automatic data transmission functions such as TCP / IP, wifi, Bluetooth, Zigbee and the like, and automatically transmits images to a data center.

[0032] The baffle 25 is installed inside the connecting pipe 21, and the baffle 25 can be switched between a stopping state and an open state relative to the connecting pipe 21. When the baffle 25 is in the stopping state, the baffle 25 blocks the excrement 3 flushed out of the water outlet, and the camera 26 photographs the excrement 3. When the baffle 25 is in the open state, the excrement 3 falls out of the connecting pipe 21. Specifically, the baffle 25 comprises a stopping portion 250 and an extending portion 251, and the extending portion 251 extends from the end of the stopping portion 250. The included angle between the extending portion 251 and the stopping portion 250 is obtuse. The baffle 25 is rotationally installed on the connecting pipe 21, and the rotation point of the baffle 25 is the intersection of the extending portion 251 and the stopping portion 250. When the baffle 25 is in the stopping state, the stopping portion 250 is located on the water flow channel and intercepts the excrement 3 in the water flow channel. When the baffle 25 is in the open state, the extending portion 251 is attached to the flushing wall 210 and is located on the same straight line to prevent blocking the water flow. The baffle 25 is also provided with a plurality of water leakage holes 252, and the plurality of water leakage holes 252 are uniformly arranged on the extending portion 251 and the stopping portion 250. The water leakage holes 252 allow the water flow to pass while blocking the excrement 3.

[0033] The camera 26 is installed on the mounting wall 211 of the connecting pipe 21. Since the mounting wall 211 is located at the highest position of the connecting pipe 21, the camera 26 can reduce the probability of water entering. The camera 26 is electrically connected to the main control board 24, and the main control board 24 controls the working of the camera 26.

[0034] The light source 27 is installed on the mounting wall 211 of the connecting pipe 21. Since the mounting wall 211 is located at the highest position of the connecting pipe 21, the light source 27 can reduce the probability of water entering. Specifically, the light source 27 is a ring-shaped lamp, which surrounds the camera 26. The light source 27 is electrically connected to the main control board 24, and the main control board 24 controls the working of the light source 27.

[0035] The driving member 28 is connected to the baffle 25, and the driving member 28 drives the baffle 25 to move. In this embodiment, the driving member 28 is a motor, which drives the baffle 25 to rotate. The driving member 28 is electrically connected to the main control board 24, and the main control board 24 controls the working of the driving member 28.

[0036] The sensor 29 is installed in the connecting pipe 21. The sensor 29 is a sensor capable of sensing the flow rate of water. The sensor 29 is electrically connected to the main control board 24, and the sensor 29 transmits the collected signals to the main control board 24.

[0037] When the device for automatically collecting images of fecal samples is used, after a user uses the closestool 1, the flush button on the closestool 1 is pressed, the feces 3 will enter the collecting structure 2 under the push of the water flow, the sensor 29 senses the increase of the flow rate, the main control board 24 controls the baffle 25 to rotate and be in the blocking state, and blocks the feces 3 from continuing to flow into the sewer pipe, and at the same time, the light source 27 is turned on. When the sensor 29 senses that the flow rate of water is small, at this time, the main control board 24 controls the camera 26 to collect images. After the image collection is completed, the main control board 24 turns off the light source 27, and at the same time, the driving member 28 works, so that the baffle 25 is in the open state, and the feces 3 will fall into the sewer pipe. The automatic image collection work is completed, and the main control board 24 stores the collected images in the local and uploads them to the designated server.

[0038] Through the above design, the device for automatically collecting images of fecal samples can automatically collect a large number of high-definition fecal images with consistent scenes without changing people's lifestyle, provide reliable and high-value training sets for fecal image analysis, help to improve the accuracy of algorithm analysis, and reveal more information related to gastrointestinal diseases.

[0039] The above embodiments only express several implementation manners of the present application, the description is more specific and detailed, but cannot be understood as the limitation of the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, several modifications and improvements can be made, which are equivalent modifications and evolutions of the above embodiments according to the essential technology of the present application, and these all belong to the protection scope of the present application.
