Description

Technical Field

[0001] The utility model relates to the technical field of toilets, in particular to a toilet urine detection 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 is roughly divided into the following steps: the first step is to collect urine, the second step is to soak the urine in the test paper, 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] The common urine collection method for urine testing toilets on the market is: after the user sits on the seat, the urine collecting rod extends from one side of the seat, the user outputs urine on the urine collecting rod, and then the urine suction system transmits the collected urine to the urine analysis device for urine analysis, outputs the urine test data to the mobile phone APP, and finally the urine collecting rod extends back to the hidden position in the seat. However, when these urine collecting rods on the market are extended to collect urine, the urine collecting surface is too close to the seat, and the urine collecting rod is equivalent to extending on a horizontal plane. Especially when female users are outputting urine, urine may splash onto their skin, affecting the user experience. Utility Model Content

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

[0006] To achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The utility model also provides an intelligent toilet with the toilet urine detection device.

[0008] According to the first aspect of the present invention, the urine detection device for a toilet includes a urine collecting rod and a motor, which are installed under the seat ring of the toilet. The urine collecting rod includes a urine collecting part, and the output shaft of the motor faces one side of the toilet cavity. One end of the urine collecting rod is connected to the output shaft, and the motor can drive the urine collecting rod to rotate around the output shaft. As the urine collecting rod rotates, the urine collecting part can enter the toilet cavity.

[0009] It should be noted that there are many ways to realize that the urine receiving part rotates with the urine receiving rod and enters the toilet cavity, such as installing the motor tilted upward to make the rotation center of the urine receiving rod tilted upward, designing the urine receiving rod to be curved, designing the angle between the output shaft and the urine receiving rod to be an obtuse angle, or any combination of the above three methods, all of which can realize the urine receiving part entering the toilet cavity. It should be noted that the placement of the motor, the shape of the urine receiving rod, the connection method between the motor and the urine receiving rod, etc. should be based on the premise that these designs do not affect the basic performance and appearance of the toilet.

[0010] The toilet urine detection device according to the embodiment of the utility model has at least the following beneficial effects:

[0011] The utility model changes the movement trajectory of the nearly horizontal extension of the traditional urine collecting rod, and changes the movement trajectory of the urine collecting rod from horizontal extension to downward rotation extension by designing the direction of the motor output shaft and the transmission mode of the motor and the urine collecting rod. The lateral depth of the urine collecting part entering the toilet cavity can be controlled by controlling the upward inclination angle of the output shaft or the bending degree of the urine collecting rod, ensuring that after the urine collecting rod reaches the urine collection position, the urine collecting surface is located in the urine dripping area of ​​the user and is far away from the seat ring, so that urine will not splash onto the skin.

[0012] According to some embodiments of the utility model, the output shaft is arranged to be tilted upward. By controlling the motor to be installed tilted upward, the output shaft is tilted upward, so that the rotation center of the urine collecting rod is tilted upward. When the urine collecting rod rotates around the output shaft, its motion trajectory is obliquely downward, and it has both a tendency to move downward and a tendency to move toward the middle of the toilet cavity (the user's urine dripping area), ensuring that the urine collecting surface is located in the user's urine dripping area and is far away from the seat ring. Since the motor needs to be installed tilted, the height of the seat ring may be higher than that of an ordinary seat ring, so it is necessary to consider minimizing the height of the seat ring. In order to solve this problem, a small motor can be selected, such as a motor with a diameter of about 15mm. The motor connection hole of the urine collecting rod is eccentrically designed, that is, the position of the motor connection hole of the urine collecting rod is as high as possible, which can save space on the top of the urine collecting rod. Through the above design, the height of the seat ring can be controlled at about 35mm, which will not make the height of the seat ring appear too high, thereby increasing the aesthetics of the product.

[0013] According to some embodiments of the utility model, the urine collecting rod is in an arc shape as a whole and is bent toward one side of the toilet chamber. The arc design can increase the coverage area of ​​the urine collecting part in the user's urine dripping area and improve the urine collection volume. The arc curvature of the urine collecting rod can match the arc curvature of the inner edge of the seat ring, so that the urine collecting rod is completely hidden under the seat ring and does not affect the appearance of the toilet.

[0014] According to some embodiments of the utility model, the urine collecting rod further comprises a connecting rod portion, the front end of the connecting rod portion is snap-connected to the urine collecting portion, and the end of the connecting rod portion is connected to the output shaft. Furthermore, the front end of the connecting rod portion is connected to the urine collecting portion via a snap. The urine collecting rod is detachable, and the user can remove the urine collecting portion separately for cleaning, thereby avoiding the problem of urine residue in the urine collecting rod after long-term use. Urine residue can lead to inaccurate urine detection, and cleaning the urine collecting rod can improve the accuracy of detection.

[0015] According to some embodiments of the utility model, the urine receiving part has a urine receiving trough, the trough opening of the urine receiving trough faces the toilet chamber side of the toilet, the trough opening of the urine receiving trough is covered with a urine receiving panel, the urine receiving panel is provided with a plurality of first through holes, the urine receiving trough includes a urine suction channel and a urine receiving channel, the urine suction channel is a closed cavity, the urine receiving channel is connected with the first through holes, the urine suction channel and the urine receiving channel are connected through a urine inlet, and the side wall of the urine suction channel is pierced with a first urine suction needle. Furthermore, the urine inlet is located at the front end of the urine suction channel, the end of the urine suction channel is recessed downward to form a urine collecting trough, and the first urine suction needle is located at the bottom of the urine collecting trough. Specifically, the closed urine suction channel can be realized by designing an L-shaped bone position below the urine receiving panel, and the urine receiving panel and the urine receiving trough are friction-welded to form a closed urine suction channel. When urine starts to be sucked, the closed urine suction channel becomes a negative pressure chamber, and urine enters the urine suction channel from the first through hole on the urine receiving panel, and then flows into the urine suction channel through the urine inlet. The innovation of this structure is that there is no need to install a urine suction hose in the urine receiving trough, and the urine suction channel can play the role of the urine suction hose. The negative pressure principle is used to simplify the structure, and the closed urine suction channel has strong stability. There is no resistance of the hose itself when sucking urine, and the urine can be sucked away quickly.

Synchronously, the first air valve is opened and the second air valve is closed (purpose: when the vacuum pump is pumping air, it is ensured that gas does not flow out from the air outlet of the air pump, affecting the vacuum state of the urine suction system), and urine is sucked into the urine collection bottle. After enough urine is sucked, the vacuum pump stops working, the urine collecting rod is reset (hidden in the seat ring), and the urine suction action is started. End; (3) Urine titration: After the urine suction action is completed, the peristaltic pump works to suck the liquid in the urine collection bottle into the titration needle, and then the urine is dripped into the test paper through the titration needle. The test paper outputs the test result to the central control display system. The titration is completed and the peristaltic pump stops working; (4) Urine discharge: After the titration is completed, the air pump starts to blow air. Synchronously, the second air valve opens and the first air valve closes (purpose: to ensure that the gas does not flow out from the vacuum pump's exhaust port during blowing, affecting the blowing efficiency), and the remaining urine in the urine collection bottle is blown away. The blown away urine is discharged through the first through hole of the urine receiving rod. Then the peristaltic pump starts working to discharge the excess urine in the peristaltic pump to the urine leakage port on the movement, the air pump is turned off, the second air valve is closed, and urination is completed; (5) Backwashing of the urine collection circuit and the titration circuit: After urination is completed, clean water enters the urine collection bottle from the second liquid inlet to clean the urine collection circuit, and the cleaning water is discharged from the first through hole of the urine collection rod. The peristaltic pump is turned on to clean the titration circuit, and clean water is discharged from the urine leakage port on the movement. The backwashing of the urine collection circuit and the titration circuit is completed, and the second liquid inlet stops taking in water, and the peristaltic pump is turned off; (6) Drying of the urine collection circuit and the titration circuit: The air pump continues to work, the peristaltic pump is turned on, and the urine collection circuit and the titration circuit are dried respectively to blow off the residual water. The urine collection and backwashing components can realize a series of actions such as automatic urine suction, urination, and cleaning to minimize the urine residue in the system.

[0017] According to some embodiments of the utility model, one end of the first urine absorbing needle penetrates from the end of the urine absorbing channel and communicates with the urine absorbing channel, and the other end is communicated with the urine absorbing tube. Furthermore, the other end of the first urine absorbing needle is penetrated through the front end of the connecting rod, and the urine absorbing tube is arranged backward along the inner wall of the connecting rod from the front end of the connecting rod, extends to the end of the connecting rod and penetrates from its inner wall. Specifically, the first urine absorbing needle is hot-melted on the connecting rod, and the insertion depth of the first urine absorbing needle in the urine absorbing channel can be designed to be about 1 mm, and the urine absorbing tube is not exposed but hidden inside the connecting rod.

[0018] According to some embodiments of the present invention, the urine collection and backwashing assembly further includes a flow meter and a water inlet pressure regulating valve, wherein the flow meter is connected to the water inlet pressure regulating valve, and the flow meter is connected to the second liquid inlet. Washing water enters from the water inlet pressure regulating valve and enters the second liquid inlet after passing through the flow meter.

[0019] According to some embodiments of the utility model, the urine collecting bottle is provided with a first cavity and a second cavity, the first liquid inlet and the urine outlet are located on the first cavity, a third liquid inlet is provided between the first cavity and the second cavity, the third liquid inlet is connected to the first cavity and the second cavity, a liquid discharge port is provided at the bottom of the second cavity, a fourth liquid inlet is also provided on the first cavity and the position of the fourth liquid inlet is higher than the third liquid inlet, and the liquid discharge port and the fourth liquid inlet are connected through an external pipe. Further, the position of the third liquid inlet is above the middle of the first cavity. Further, a liquid level sensor is provided on the side wall of the second cavity. Further, the urine outlet is a second urine absorbing needle, which penetrates from the top of the first cavity and extends downward to the bottom of the first cavity. The second urine absorbing needle is inserted into the bottom of the first cavity to fully absorb the urine in the first cavity. The working principle of the urine collecting bottle is as follows: urine enters the first cavity through the first liquid inlet. When the urine level in the first cavity rises to the third liquid inlet, urine begins to enter the second cavity. When the liquid level sensor senses that the liquid level in the second cavity reaches the predetermined position, the vacuum pump stops sucking urine. In this way, the urine in the second cavity is the user's first-stage urine, and the urine in the first cavity is the user's middle-stage urine. The middle-stage urine in the first cavity is drawn away for urine titration. Since the position of the third liquid inlet is higher than the lowest point in the second cavity, a drainage port is specially set at the bottom of the second cavity, and a fourth liquid inlet is set at a position higher than the third liquid inlet in the first cavity. During the urination and drainage process of the urine collecting bottle, urine and cleaning water can be fully discharged from the second cavity to the first cavity, and then discharged from the first cavity. The urine collecting bottle is designed with two cavities. During the urine suction process, the middle-stage urine can be automatically separated, which can make the test results more accurate. When urine and cleaning water are exchanged at the third liquid inlet, there is no resistance from the hose, the flow rate will increase, and the detection efficiency will be improved. Moreover, since the drain port and the third liquid inlet are provided, the urine and flushing water in the second cavity can be synchronously discharged into the first cavity from the third liquid inlet and the drain port in the form of dual channels during urination and backwashing, which effectively improves the detection efficiency.

[0020] According to some embodiments of the utility model, an air inlet cover is provided on the top of the second cavity, the air inlet cover is sealed with the body of the urine collection bottle, and the first air inlet and the second air inlet are provided on the air inlet cover.

The cleaning water flows into the water inlet channel through the cleaning pipe, and then sprays out from the second through hole to clean the surface of the urine receiving part. The water inlet channel is small and narrow, and a strong water pressure can be formed.

[0022] According to some embodiments of the utility model, the urine collection and backwashing assembly further includes a reversing valve, the water inlet of the reversing valve is connected to a water source, the normally closed water outlet of the reversing valve is connected to the second liquid inlet, and the normally open water outlet of the reversing valve is connected to the cleaning pipe. Furthermore, the water inlet of the reversing valve is connected to a flow meter. When the urine receiving circuit and the titration circuit are backwashed, the reversing valve is opened (i.e., the normally closed water outlet is opened). After the backwashing of the urine receiving circuit and the titration circuit is completed, the reversing valve is closed, and the cleaning operation of the cleaning device is switched at this time. Water flows through the normally open water outlet of the reversing valve to the cleaning device, and the urine stains remaining on the surface of the urine collecting rod are cleaned. After the cleaning is completed, the water inlet of the reversing valve stops taking in water.

The seat ring and the seat ring lower shell are sealed to prevent water or water vapor in the toilet from entering the seat ring to avoid motor and heating wire failure. The seat ring and the seat ring lower shell can be connected by high-frequency induction welding. The principle of high-frequency induction welding is mainly based on Faraday's law of electromagnetic induction and skin effect. Under the action of high-frequency electromagnetic field, the charge on the surface of the workpiece is excited to form eddy currents. These eddy currents are heated by resistance and gradually increase with the change of time, thereby heating the surface of the workpiece to the required temperature to achieve the purpose of welding. High-frequency induction welding is faster and more accurate than ordinary friction welding. Through the above design, the seat ring can be made IPX4 waterproof. In addition, the lower shell of the seat ring located at the top of the accommodating groove fits tightly with the seat ring, providing a supporting force for the seat ring. When the user sits on the seat ring, the pressure on the inner side of the seat ring will be greater. With this supporting force, the structural strength of the seat ring can be improved.

DETAILED DESCRIPTION

[0041] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0042] Reference Figure 1-4 A urine detection device for a toilet includes a urine collecting rod 100 and a motor 200. The urine collecting rod 100 and the motor 200 are installed below a seat ring 300 of the toilet. The urine collecting rod 100 includes a urine collecting portion 110. An output shaft 210 of the motor 200 faces one side of a toilet cavity. One end of the urine collecting rod 100 is connected to the output shaft 210. The motor 200 can drive the urine collecting rod 100 to rotate around the output shaft 210. As the urine collecting rod 100 rotates, the urine collecting portion 110 can enter the toilet cavity.

[0043] It should be noted that there are many ways to realize that the urine receiving part 110 rotates with the urine receiving rod 100 and enters the toilet cavity, such as the motor 200 is installed tilted upward to make the rotation center of the urine receiving rod 100 tilted upward, or the urine receiving rod 100 is designed to be curved, or the angle between the output shaft 210 and the urine receiving rod 100 is designed to be an obtuse angle, or any combination of the above three methods, all of which can realize the urine receiving part 110 entering the toilet cavity. It should be noted that the placement of the motor 200, the shape of the urine receiving rod 100, the connection method of the motor 200 and the urine receiving rod 100, etc. should be based on the premise that these designs do not affect the basic performance and appearance of the toilet.

[0044] The utility model changes the movement trajectory of the nearly horizontal extension of the conventional urine collecting rod 100, and changes the movement trajectory of the urine collecting rod 100 from horizontal extension to downward rotation extension by designing the orientation of the output shaft 210 of the motor 200 and the transmission mode of the motor 200 and the urine collecting rod 100. The lateral depth of the urine collecting portion 110 entering the toilet cavity can be controlled by controlling the upward tilt angle of the output shaft 210 or the bending degree of the urine collecting rod 100, so as to ensure that after the urine collecting rod 100 reaches the urine collection position, the urine collecting surface is located in the urine dripping area of ​​the user and is far away from the seat ring 300, so that urine will not splash onto the skin.

[0045] In some embodiments of the utility model, the output shaft 210 is arranged to be tilted upward. By controlling the motor 200 to be installed tilted upward, the output shaft 210 is tilted upward, so that the rotation center of the urine receiving rod 100 is tilted upward. When the urine receiving rod 100 rotates around the output shaft 210, its motion trajectory is obliquely downward, and it has both a tendency to move downward and a tendency to move toward the middle of the toilet cavity (the urine dripping area of ​​the user), so as to ensure that the urine receiving surface is located in the urine dripping area of ​​the user and is far away from the seat ring 300. Since the motor 200 needs to be installed tilted, the height of the seat ring 300 may be higher than that of the ordinary seat ring 300, so it is necessary to consider minimizing the height of the seat ring 300. In order to solve this problem, a small motor 200 can be selected, such as a motor 200 with a diameter of about 15 mm, and the motor 200 connection hole of the urine receiving rod 100 is eccentrically designed, that is, the position of the motor 200 connection hole of the urine receiving rod 100 is as close to the top as possible, so that the top space of the urine receiving rod 100 can be saved. Through the above design, the height of the seat ring 300 can be controlled at about 35 mm, which will not make the height of the seat ring 300 appear too high, thereby increasing the aesthetics of the product.

[0046] In some embodiments of the utility model, the urine collecting rod 100 is in an arc shape and is bent toward one side of the toilet cavity. The arc design can increase the coverage area of ​​the urine collecting part 110 in the user's urine dripping area and increase the urine collection volume. The arc curvature of the urine collecting rod 100 can match the curvature of the inner edge of the seat ring 300, so that the urine collecting rod 100 is completely hidden under the seat ring 300, without affecting the appearance of the toilet.

[0047] In some embodiments of the present invention, referring to Figure 5 The urine collecting rod 100 further includes a connecting rod 120, the front end of the connecting rod 120 is snap-connected with the urine collecting part 110, and the end of the connecting rod 120 is connected with the output shaft 210. Furthermore, the front end of the connecting rod 120 is connected with the urine collecting part 110 by a snap-on buckle. The urine collecting rod 100 is detachable, and the user can remove the urine collecting part 110 separately for cleaning, so as to avoid the problem of urine residue after long-term use of the urine collecting rod 100. Urine residue will lead to inaccurate urine detection. Cleaning the urine collecting rod 100 can improve the accuracy of detection.

Furthermore, the urine inlet 170 is located at the front end of the urine suction channel 150, and the end of the urine suction channel 150 is recessed downward to form a urine collecting groove 180, and the first urine suction needle 190 is located at the bottom of the urine collecting groove 180. Specifically, the closed urine suction channel 150 can be realized by designing an L-shaped bone position under the urine receiving panel 140, and the urine receiving panel 140 and the urine receiving trough are friction welded to form a closed urine suction channel 150. When urine suction begins, the closed urine suction channel 150 becomes a negative pressure chamber, and urine enters the urine receiving channel 160 from the first through hole 141 on the urine receiving panel 140, and then flows into the urine suction channel 150 through the urine inlet 170. The innovative point of this structure is that there is no need to install a urine suction hose in the urine receiving trough, and the urine suction channel 150 can play the role of a urine suction hose. The negative pressure principle is used to simplify the structure, and the closed urine suction channel 150 has strong stability. There is no resistance of the hose itself when sucking urine, and the urine can be sucked away quickly.

The motor 200 is placed in the closed space surrounded by the seat ring 300 and the seat ring 300 lower shell, and the output shaft 210 is passed through the side wall of the receiving groove 810 through the shaft seal. The seat ring 300 and the seat ring 300 lower shell are sealed to prevent water or water vapor in the toilet from entering the seat ring 300, so as to avoid failure of the motor 200 and the heating wire. The seat ring 300 and the lower shell of the seat ring 300 can be connected by high-frequency induction welding. The principle of high-frequency induction welding is mainly based on Faraday's law of electromagnetic induction and skin effect. Under the action of high-frequency electromagnetic field, the charge on the surface of the workpiece is excited to form eddy currents. These eddy currents are heated by resistance and gradually increase over time, thereby heating the surface of the workpiece to the required temperature to achieve the purpose of welding. High-frequency induction welding is faster and more accurate than ordinary friction welding. Through the above design, the seat ring 300 can be made IPX4 waterproof. In addition, the lower shell of the seat ring 300 located at the top of the accommodating groove 810 fits tightly with the seat ring 300, providing a supporting force for the seat ring 300. When the user sits on the seat ring 300, the pressure inside the seat ring 300 will be relatively large. With this supporting force, the structural strength of the seat ring 300 can be improved.
