Description

Technical Field

[0001] The utility model relates to the technical field of intelligent toilets, in particular to a urine separation device and an intelligent toilet. Background Art

[0002] At present, the functions of smart toilets are becoming more and more abundant. Among them, smart toilets with urine testing function have become increasingly popular among users. They can not only meet the needs of comfortable toileting, but also understand one's own health status at any time through urine testing and prevent related diseases.

[0003] The urine test process for users generally involves the following steps: the first step is to collect urine, the second step is to soak the test paper with urine, the third step is for the detection unit to analyze the test paper, the fourth step is to export the urine test data, and the fifth step is to automatically clean the urine collection device.

[0004] As we all know, when performing urine tests in hospitals, doctors usually ask patients to collect midstream urine because the test results of midstream urine are more accurate. In the existing technology, most smart toilets do not use urine separation devices and directly sample and test urine. This test result will obviously have a large deviation. Only a few smart toilets use urine separation devices to distinguish between first-stream and midstream urine. Generally, urine collection bottles and urine buffer bottles are used for urine separation. Urine first enters the urine buffer bottle. The urine remaining in the urine collection bottle is considered midstream urine. Then, a urine needle is used to extract the urine in the urine collection bottle for analysis. However, this technology also has certain technical defects: the urine collection bottle and urine buffer bottle are connected by a hose. Due to the flowing nature of the liquid, it is difficult to actively distinguish between first-stream and midstream urine. First-stream urine can still exist in the urine collection bottle, resulting in deviations in the test results. Utility Model Content

[0005] The present invention aims to solve at least one of the above-mentioned technical problems in the related art to a certain extent. To this end, the present invention provides a urine separation device.

[0028] Reference Figure 1-3 A urine separation device includes a urine collecting bottle 100 and a urine isolation plate 200. The urine collecting bottle 100 has a urine collecting cavity. A through groove 110 is opened on the side wall of the urine collecting bottle 100. The urine isolation plate 200 is arranged horizontally and can move in the horizontal direction. The urine isolation plate 200 can be inserted into the urine collecting cavity through the through groove 110 to separate the urine collecting cavity into an upper and lower urine absorption area 120 and a buffer area 130. The urine absorption area 120 is provided with a urine outlet and a urine inlet 121.

[0029] Working principle: In the initial state, the main body of the urine barrier 200 is located outside the urine collecting bottle 100, and only the end of the urine barrier 200 is inserted in the through groove 110. Urine enters the urine collecting cavity through the urine inlet 121 and flows into the buffer zone 130 below. After a period of urination, the initial urine has been collected. Then the urine barrier 200 moves forward and is inserted into the urine collecting cavity. After the urine barrier 200 is inserted into place, a urine absorption area 120 is formed above the urine barrier 200. At this time, if urine is continued to be injected, the urine will remain in the urine absorption area 120, so that the urine collected in the urine absorption area 120 is completely mid-stream urine and will not be mixed with initial urine. Then the urine collection component absorbs the mid-stream urine through the urine outlet for urine testing. After the mid-stream urine is absorbed, the urine barrier 200 moves in the opposite direction to return to the initial position.

[0030] Some embodiments of the present invention further include a screw rod 310 assembly for driving the movement of the urine isolation plate 200. The screw rod 310 assembly includes a screw rod 310, a moving nut 320, and a stepper motor 330 for driving the screw rod 310. The screw rod 310 assembly is disposed outside the urine collection bottle 100, and the moving nut 320 is threadedly connected to the screw rod 310. One end of the urine isolation plate 200 is inserted into the urine collection bottle 100, and the other end is fixedly connected to the moving nut 320. After receiving a signal from the main control board, the stepper motor 330 drives the screw rod 310 to begin forward rotation. Since the moving nut 320 is threadedly connected to the screw rod 310 and is screwed to the urine isolation plate 200, the urine isolation plate 200 begins to move rightward under the drive of the moving nut 320. After the urine isolation plate 200 moves into position, the urine collection chamber is divided into two enclosed upper and lower urine absorption areas 120 and a buffer area 130. After the middle portion of urine is sucked away, the main control board outputs a signal to the stepper motor 330, which drives the screw 310 to begin reverse rotation. The urine barrier 200, driven by the motion nut 320, moves leftward and returns to its initial position. Using the screw 310 to drive the urine barrier 200 in linear motion offers advantages such as high transmission accuracy, smooth motion, and ease of control.

[0031] In some embodiments of the present invention, a first travel switch 400 is further included. The first travel switch 400 is disposed outside the urine collection bottle 100 and is electrically connected to the stepper motor 330. A first abutment 210 is provided on the other end of the urine isolation plate 200. When the urine isolation plate 200 moves forward and is inserted into the urine collection cavity, the first abutment 210 triggers the first travel switch 400. The urine isolation plate 200 moves forward until it contacts the first travel switch 400. The first travel switch 400 outputs a signal to the main control board, which in turn outputs a signal to the stepper motor 330 to stop movement, thereby achieving automated control.

[0032] In some embodiments of the present invention, a second travel switch 500 is further included. The second travel switch 500 is disposed outside the urine collection bottle 100 and is electrically connected to the stepping motor 330. A second abutment 220 is provided on the other end of the urine isolation plate 200. When the urine isolation plate 200 moves in the reverse direction by a set distance, the second abutment 220 can trigger the second travel switch 500. When the urine isolation plate 200 moves in the reverse direction and touches the second travel switch 500, the second travel switch 500 outputs a signal to the main control board, which in turn outputs a signal to the stepping motor 330 to stop the movement, causing the urine isolation plate 200 to stop moving and return to its initial position, thereby achieving automated control.

[0033] In some embodiments of the present invention, a urine outlet is formed on the top wall of the urine absorbing area 120. A urine collection needle 600 is inserted into the outlet. The upper end of the urine collection needle 600 extends out of the urine collecting bottle 100, and the lower end extends to the bottom of the urine absorbing area 120. The lowest point of the urine collection needle 600 is located at the bottom of the urine absorbing area 120, which facilitates the rapid removal of urine in the middle of the urine.

[0034] In some embodiments of the present invention, a first sealing silicone 710 is provided on the through groove 110. The first sealing silicone 710 is embedded around the through groove 110, so that the through groove 110 and the diaper isolation board 200 form a sealing structure.

[0035] In some embodiments of the present invention, a second sealing silicone rubber 720 is provided on the inner wall of the urine collection chamber. The second sealing silicone rubber 720 has a groove into which the edge of the urine barrier 200 can be inserted and move along the groove, and the groove is coated with lubricating grease. Furthermore, a groove for inserting the second sealing silicone rubber 720 is formed on the inner wall of the urine collection chamber. The second sealing silicone rubber 720 is inserted into the urine collection bottle 100, and the urine barrier 200 moves within the groove of the second sealing silicone rubber 720, thereby ensuring airtightness. Once sealed, the urine absorption area 120 and the buffer area 130 are completely isolated, preventing urine leakage. The lubricating grease improves the smoothness of the movement of the urine barrier 200 within the groove.

[0036] In some embodiments of the present invention, the urine collecting cavity includes a left cavity 140 and a right cavity 150, and the urine barrier 200, the through groove 110, the urine outlet and the urine inlet 121 are all arranged in the left cavity 140. The urine barrier 200 can be inserted into the left cavity 140 through the through groove 110 to separate the left cavity 140 into an upper and lower urine absorption area 120 and a buffer area 130. A liquid hole 160 and an air hole 170 are provided between the left cavity 140 and the right cavity 150. The liquid hole 160 is located in the buffer area 130, and the liquid hole 160 connects the buffer area 130 and the right cavity 150. The air hole 170 is located in the urine absorption area 120, and the air hole 170 connects the urine absorption area 120 and the right cavity 150. An air inlet 151 and an air extraction port 152 are provided on the upper part of the right cavity 150, and a liquid discharge port 180 is provided at the bottom of the left cavity 140 and the right cavity 150. Urine enters the left cavity 140 through the urine inlet 121, the liquid level in the left cavity 140 begins to rise, and enters the right cavity 150 through the liquid hole 160. The right cavity 150 is provided to facilitate the addition of the air inlet 151 and the air extraction port 152 structure, making the spatial layout more reasonable. The air inlet 151 is connected to an external air pump, and the air extraction port 152 is connected to an external vacuum pump. The urine collection bottle 100 and the entire urine collection system are evacuated through the air extraction port 152, and urine is sucked into the urine inlet 121 using the negative pressure principle. The air hole 170 is used to connect the air pressure of the urine absorption area 120 and the right cavity 150 to ensure that when the right cavity 150 is evacuated, the urine absorption area 120 can form a negative pressure, thereby absorbing urine. Air is blown into the urine collection bottle 100 through the air inlet 151 to blow away the remaining urine in the urine collection bottle 100.

[0037] In some embodiments of the present invention, a liquid level sensor 800 is provided on the side wall of the right cavity 150. Urine in the left cavity 140 enters the right cavity 150 through the liquid hole 160, and the liquid level in the right cavity 150 begins to rise. When the liquid level in the right cavity 150 reaches the sensing area of the liquid level sensor 800, the liquid level sensor 800 outputs a signal to the main control board, which in turn outputs a signal to the stepper motor 330 to initiate operation. This step indicates that the collection of the first-stream urine has been completed and the collection of the middle-stream urine has begun.
