[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] like Figure 1 As shown, the present invention provides an intelligent urine metering device, comprising:

[0045] The urinal 1 is used to provide a urine storage area to temporarily store urine after each urination;

[0046] The infrared sensor 2 is arranged in the toilet bowl 1, the infrared sensor 2 is located above the storage area, and the measuring end of the infrared sensor 2 is vertically oriented toward the storage area, and is used to detect the distance from the liquid surface in the storage area to the measuring end after each urination;

[0047] The host 3 is arranged on the toilet bowl 1. The host 3 is electrically connected to the infrared sensor 2. The host 3 is used to control the infrared sensor 2 to detect and obtain the detection distance before and after each urination, so as to calculate the liquid level height difference;

[0048] The host 3 presets the specification information of the storage area, so that after the host 3 obtains the liquid level height difference, it calculates the urine volume according to the specification information of the storage area, and records the urine volume and urination time.

[0049] The metering device of the present invention is provided with a host 3 on the toilet 1, and an infrared sensor 2 is provided in the toilet 1, and the host 3 is connected to the infrared sensor 2 to measure the liquid level height in the urine storage area in the toilet 1, so that before each urination, the initial liquid level height (i.e., the liquid level height of the retained water in the urine storage area) is obtained, and after the urination is completed, the liquid level height (i.e., the liquid level height of the retained water and urine mixture in the urine storage area) is obtained again, and by calculating the difference between the two liquid level heights, the height of the urine rising in the urine storage area can be obtained, and based on the specification information (cross-sectional area) of the storage area, the urine volume can be calculated, thereby obtaining the urine volume of this urination and automatically recording the urine volume and urination time.

[0050] In order to reduce the difficulty of calculation, the storage area is set as a regular cavity at the beginning of the design of the toilet 1 so that its cross-sectional area remains unchanged as the liquid level increases. Of course, the storage area is the bottom section of the conventional toilet 1 (toilet, urinal), that is, the storage area is located at the bottom of the toilet 1 to store liquid, and can accommodate the urine volume of a normal person at one time. For example, the regular storage area is set to 1000mL, and the urine volume of a normal person at one time is 250-500mL.

[0051] Compared with the existing metering devices, the metering device of the present invention can automatically measure and calculate the urine volume and record the urine volume and urination time by the host 3 after urination is completed by obtaining the data of the infrared sensor 2. After urination is completed, it can be directly flushed with water, which is more convenient to operate. After urination, the host 3 cooperates with the infrared sensor 2 to measure, calculate and record, which has high accuracy and more convenient metering operation.

[0052] Of course, the present invention may also not make a special design for the storage area of ​​the toilet 1, that is, keep the structure of the existing toilet 1, then it is necessary to perform a three-dimensional scan on the storage area of ​​the toilet 1 to obtain the relationship between its cross-sectional area and the liquid level height (or obtain it from the toilet modeling data), so as to obtain the increase in urine by an approximate calculation method, that is, set the unit height to calculate the volume step by step and sum it up, such as taking each millimeter of height as a unit, and taking the middle value between the initial cross-sectional area and the cross-sectional area after rising 1mm as the average cross-sectional area, calculating the unit volume, and then accumulating each unit volume to obtain the urine volume.

[0053] Although the above method can complete the measurement, the measurement accuracy is related to the unit height setting and the calculation is complicated. Therefore, it is more recommended to conduct regular design of the storage area at the beginning of the design. Based on this, the following preferred embodiments are provided.

[0054] like Figure 1 , Figure 2 As shown, the toilet 1 includes a bucket body 11, a urination channel 12 is formed inside the bucket body 11, the urination channel 12 is formed with a liquid inlet 111 in the bucket body 11, and a liquid discharge port 112 is formed at the bottom of the bucket body 11;

[0055] A liquid storage barrel 13 is installed at the bottom of the bucket body 11, the upper end of the liquid storage barrel 13 is connected to the liquid discharge port 112, and the lower end of the liquid storage barrel 13 is connected to the siphon tube 14;

[0056] When the liquid level in the liquid storage barrel 13 reaches a certain height, the siphon tube 14 reaches a working condition to drain the liquid in the liquid storage barrel 13 , and the liquid storage barrel 13 constitutes a urine storage area.

[0057] Specifically, the liquid storage barrel 13 is installed at the bottom of the toilet bowl 1 as a urine storage area. The internal space of the liquid storage barrel 13 is regular, which is convenient for measurement and calculation. Urine enters the urination channel 12 from the liquid inlet 111 of the bucket body 11, and then enters the liquid storage barrel 13 from the liquid discharge port 112, thereby mixing with the water in the liquid storage barrel 13, so that the liquid level in the liquid storage barrel 13 rises;

[0058] During flushing, when the liquid level in the liquid storage barrel 13 is higher than the highest point of the siphon 14, the siphon 14 starts to work, and the mixture of urine and water is discharged from the bottom of the liquid storage barrel 13, and the remaining water remains in the liquid storage barrel 13 to prevent odor and form an initial liquid level.

[0059] Since urine needs to fall into the liquid storage barrel 13 from the liquid discharge port 112, during this process, urine drops on the liquid surface and easily causes fluctuations, which affects the measurement accuracy of the infrared sensor 2. Therefore, in order to reduce the detection error, the following preferred embodiments are provided.

[0060] like Figure 2, Figure 3 As shown, a disc 15 is provided at the liquid discharge port 112, and a plurality of diversion holes 151 are provided around the disc 15. The liquid discharge port 112 is connected to the liquid storage barrel 13 through the plurality of diversion holes 151;

[0061] The infrared sensor 2 is disposed at the bottom of the wafer 15 , and the measuring end of the infrared sensor 2 is vertically oriented toward the bottom of the liquid storage barrel 13 .

[0062] Specifically, a disc 15 is provided at the discharge port 112 to seal it, and a plurality of diversion holes 151 are provided around the disc 15, so that the liquid can only be dispersed into the liquid storage barrel 13 through the plurality of diversion holes 151, and the diversion holes 151 are far away from the center and close to the peripheral wall of the liquid storage barrel 13, so that after the liquid drips into the liquid storage barrel 13, the fluctuation amplitude of the liquid level in the liquid storage barrel 13 is small, thereby improving the measurement accuracy.

[0063] Of course, the dispersed dripping of the liquid from the diversion hole 151 will still produce small fluctuations, so further, the following preferred embodiments are provided.

[0064] like Figure 2 As shown, a shield 152 is provided at the bottom of the disc 15, the upper end diameter of the shield 152 is smaller than the lower end diameter thereof, the lower end diameter of the shield 152 is smaller than the inner diameter of the liquid storage barrel 13, and an annular gap 153 is formed between the lower end of the shield 152 and the inner wall of the liquid storage barrel 13;

[0065] The liquid that falls into the liquid storage barrel 13 from the plurality of diversion holes 151 passes through the annular gap 153 and then slides down along the inner wall of the liquid storage barrel 13 .

[0066] Specifically, by setting a shield 152 at the bottom of the disc 15, an annular gap 153 is formed between the bottom of the shield 152 and the inner wall of the liquid storage barrel 13, so that after the liquid is dispersed by the diversion hole 151, it is restricted by the annular gap 153 and slides along the inner wall of the liquid storage barrel 13, further reducing the influence of the increase of the liquid on the liquid level and improving the accuracy of the measurement;

[0067] The central portion of the shield 152 protects the infrared sensor 2 at the bottom of the disc 15 , thereby preventing the infrared sensor 2 from being disturbed by urine or water and affecting the detection accuracy.

[0068] Of course, in order to enable both men and women to use this metering device, to improve its practicality and applicability and to reduce the design and manufacturing costs, the following preferred embodiments are provided.

[0069] like Figure 1 As shown, the lowest point of the mouth edge of the bucket body 11 extends horizontally forward to form a mouth pocket 16 , the mouth edge of the mouth pocket 16 is arranged horizontally, and the width of the mouth edge of the mouth pocket 16 is smaller than the width of the mouth edge of the bucket body 11 .

[0070] Specifically, the lowest point of the mouth of the bucket body 11 extends forward to form a mouth bag 16, and the mouth of the mouth bag 16 is horizontal, so that women can sit on the mouth bag 16 to urinate, and men can stand to urinate in the bucket body 11, so that it can be used in men's and women's toilets, and can also be set in the ward bathroom without distinguishing between men and women, and only one is needed.

[0071] Of course, since there are differences between men and women in the process of urination, in order to ensure the sanitary conditions of female urination, the following preferred embodiments are provided.

[0072] like Figure 1 As shown, the outer portion of the bucket body 11 protrudes outward to form a baffle 161, which is arranged around the outer edge of the mouth bag 16, and the upper surface height of the baffle 161 is lower than the mouth edge height of the mouth bag 16;

[0073] A gasket 113 is rotatably provided on the outside of the bucket body 11 . The gasket 113 can be rotated downward to be placed on the baffle 161 , or rotated upward to lean against a wall. After the gasket 113 is placed on the baffle 161 , the surface height of the gasket 113 is higher than the edge height of the mouth bag 16 .

[0074] Specifically, by setting a gasket 113 outside the bucket body 11 and a baffle 161 outside the mouth bag 16, the gasket 113 can be rotated downward and cushioned on the baffle 161, so that the surface of the gasket 113 is higher than the edge of the mouth bag 16, so that women can sit on the gasket 113 to ensure hygiene.

[0075] Of course, there are differences between the heights of women and men, and there are also different height differences between the same sex. Since the mouth bag 16 extends forward, if the height is too high, it is difficult to urinate, and if the height is too low, it is easy to splash and cause measurement errors. Based on this, the following preferred embodiments are provided.

[0076] like Figure 1 As shown, the toilet 1 also includes a vertical rail 17, which is installed on the wall, and the bucket body 11 is installed on the slide of the vertical rail 17, and the bucket body 11 can move vertically up and down on the vertical rail 17;

[0077] Among them, a locking knob is arranged on the slide of the vertical rail 17, and the locking knob restricts the movement of the bucket body 11 after being locked, and releases the restriction on the movement of the bucket body 11 after being loosened and unlocked.

[0078] Specifically, the toilet bowl 1 is composed of a vertical rail 17 and a bucket body 11, and the bucket body 11 slides up and down along the vertical rail 17. Therefore, when the height of the bucket body 11 needs to be adjusted, the bucket body 11 only needs to be moved up or down, and then locked and fixed by a locking knob;

[0079] Of course, in order to ensure that the bucket body 11 can be adjusted smoothly, a spring-connected slide is provided in the vertical rail 17, so as to support the bucket body 11 in the middle position in the initial state (ie, after the locking knob is released).

[0080] Based on the above embodiments, in order for users to better operate the metering device, the following preferred embodiments are provided.

[0081] like Figure 1 As shown, a touch screen 31 is provided on the host 3, and the touch screen 31 is used to display the QR code for user registration and login, as well as display the start and end buttons;

[0082] The host 3 is connected to the water valve of the toilet 1 to automatically control the water valve of the toilet 1 to delay flushing after the selection is completed.

[0083] Specifically, a QR code is displayed on the touch screen 31, which is convenient for users to scan and log in to their personal accounts to achieve privacy isolation. The start and end buttons can send signals to the host 3 to determine the initial reading time and the end reading time. After the end, the host 3 controls the water valve of the toilet 1 to automatically flush after a fixed delay time to keep the liquid level in the liquid storage barrel 13 as stable as possible.

[0084] Of course, the height of the bucket body 11 can be adjusted by electric control by the vertical rail 17, that is, the vertical rail 17 is an electrically controlled rail, the vertical rail 17 is connected to the host 3, and the lifting button is displayed on the touch screen 31, so that the height of the bucket body 11 can be controlled to be adjusted up and down by operating the host 3.

[0085] Since the host 3 is responsible for measuring, calculating and recording urine volume and urination time, and multiple accounts are stored in isolation, the host 3 needs to store a large amount of data. Therefore, in order to reduce the amount of data stored in the host 3, the following preferred embodiments are provided.

[0086] The host 3 has a built-in wireless communication module, and the host 3 is connected to the terminal device via the wireless communication module. The wireless communication module is used to send urine measurement data to each terminal device.

[0087] Specifically, the host 3 can send the recorded and saved data to various terminal devices (nurse handheld machines, nurse station computers, etc.) through its built-in wireless communication module, so that the host 3 only needs to temporarily store a small amount of data, which can not only reduce costs, but also forward data in real time to avoid data loss after damage.

[0088] like Figure 4 As shown, based on the above-mentioned smart meter, a metering method is provided below, comprising the following steps:

[0089] Step 100: After logging into the personal information account through the host and manually selecting to record urine volume, the host monitors the liquid level changes in the urine storage area in real time through an infrared sensor. After urinating into the toilet bowl, the manual operation of the host ends, and the host controls the flush valve of the toilet bowl to delay flushing;

[0090] Step 200, the host detects the liquid level in the urine storage area after manually selecting to record the urine volume, and detects the liquid level in the urine storage area again after the manual selection is completed to obtain the difference and calculate the urine volume;

[0091] Step 300, the host takes the middle time between the manual selection of recording urine volume and the end of manual selection as the urination time, and matches the urine volume obtained by this calculation with it and records it, and automatically logs out of the personal information account after the recording is completed.

[0092] When the metering method of the present invention is used, the user first logs in to the personal account by scanning the QR code on the touch screen 13, and then selects the start recording button. At this time, the host 3 measures the initial liquid level in the liquid storage barrel 13 through the infrared sensor 2. After urination, the end recording button is selected. At this time, the host 3 measures the liquid level of the mixed liquid in the liquid storage barrel 13 through the infrared sensor 2, and calculates the liquid level difference and the liquid increase to obtain the urine volume, and takes the middle value of the first measurement time and the second measurement time as the urination time record. After the recording is completed, it is automatically saved in the personal account and the current account is automatically exited;

[0093] After the calculation is completed (that is, after a fixed delay), the host 3 controls the water valve of the toilet 1 to open the flushing, and the water enters the liquid storage barrel 13 and the liquid level rises to a height higher than the siphon 14. The siphon 14 then works to discharge the liquid in the liquid storage barrel 13. However, since the water is affected by the flow rate and is difficult to flow continuously, after the siphon 14 discharges the liquid, the siphon effect is interrupted, and the remaining water is stored in the liquid storage barrel 13 to prevent odor and form an initial liquid level.

[0094] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
