The water replenishment tank 1 is connected to the drainage part 5 through a water replenishment pipe 4, and a positioning device is provided on the outer wall of the drainage part 5, the water level sensor 7 and the liquid detector 8 are installed in the corresponding positioning devices, and the water level sensor 7 is located on the outer side of the water seal part 6, and the liquid detector 8 is located on the outer side of the drainage part, and the controller 2 is electrically connected to the water level sensor 7 and the liquid detector 8 respectively. Preferably, it is based on the water level sensor 7 being able to monitor that the water seal of the water seal part 6 is not invalid and the liquid detector 8 being able to monitor that the drainage part 5 is draining.

[0037] In the present embodiment, the water replenishment tank 1 is equipped with an electrically controlled valve 3 for controlling the water replenishment of the water replenishment tank 1. When the electrically controlled valve 3 is opened, the water replenishment tank 1 can be drained, and the water replenishment tank 1 is connected to the drainage part 5 through the water replenishment pipe 4. When the electrically controlled valve 3 is opened, the water replenishment tank 1 replenishes water into the drainage part 5 through the water replenishment pipe 4. The water replenishment tank 1 has the same or similar structure as the water storage tank on the existing toilet. When in the bathroom, the water storage tank on the toilet can be used as the water replenishment tank 1. Of course, if the bathroom has a water storage tank, an additional water replenishment tank 1 can also be provided. A water inlet pipe 9 is provided at the water inlet end of the water replenishment tank 1, and the water inlet pipe 9 is connected to the water supply system of the building, such as Figure 8 , Fig. 9 and Fig.10 As shown, the water seal portion 6 is an existing P-shaped water seal structure or an S-shaped water seal structure or an existing floor drain water seal structure or a toilet water seal structure, such as Figure 8 and Figure 1 As shown, when it is a P-type bend water seal structure or an S-type bend water seal structure, the drainage portion 5 is a drainage pipe, such as Fig.10 As shown, when it is a toilet water seal structure, the drainage part 5 is a toilet bowl. Normally, the water seal part 6 is filled with water to form a water seal to prevent the odor, virus and bacteria in the pipe from spreading into the room.

[0038] In this embodiment, a positioning device is provided on the outer wall of the drainage portion 5, and the water level sensor 7 and the liquid detector 8 are installed in the corresponding positioning device, and the water level sensor 7 is located on the outer side of the water seal portion 6, and the liquid detector 8 is located on the outer side of the drainage portion 5. Specifically, when it is a P-type bend water seal structure, the water level sensor 7 is located on the outer side of the P-type bend water seal portion, and the liquid detector 8 is located on the outer side of the drain pipe; when it is an S-type bend water seal structure, the water level sensor 7 is located on the outer side of the S-type bend water seal portion, and the liquid detector 8 is located on the outer side of the drain pipe; when it is a floor drain water seal structure, the water level sensor 7 is located on the outer side of the floor drain water seal portion, and the liquid detector 8 is located on the outer side of the floor drain drainage portion; when it is a toilet water seal structure, the water level sensor 7 is located on the outer side of the toilet water seal portion, and the liquid detector 8 is located on the outer side of the toilet bowl drainage portion.

[0039] In this embodiment, the controller 2 is electrically connected to the water level sensor 7 and the liquid detector 8 respectively, and the controller 2 is electrically connected to the electric control valve 3. In this embodiment, the water level sensor 7 and the liquid detector 8 are both non-contact liquid level sensors, and the available model is: XKC-Y25 series, which can sense whether there is liquid in the area to be tested. For the water level sensor 7, if the water level sensor 7 detects the presence of liquid, it indicates that the water level of the water seal part 6 meets the requirements, and the absence of liquid indicates that the water level of the water seal part 6 does not meet the requirements and needs to be replenished. For the liquid detector 8, if the liquid detector 8 detects the presence of liquid, it indicates that the drainage part 5 is draining, and no liquid is detected. If liquid is detected, it indicates that the drainage part 5 has not drained the water. When the liquid detector 8 has not detected the liquid for a long time, it is necessary to replenish the water seal part 6. Furthermore, the controller 2 can be an existing programmable logic controller. In this embodiment, the preferred controller 2 is the BST-M51 series. When the controller 2 controls the electric control valve 3 to open, the water replenishment tank 1 starts to replenish water to the water seal part 6, thereby ensuring the water seal depth in the water seal part 6, avoiding the failure of the water seal of the water seal part 6 and causing the odor to spread indoors, and after replenishing water, the drainage water liquid of the water seal part 6 can be replaced, thereby avoiding the odor, bacteria and viruses exceeding the standard caused by the drainage water liquid not being replaced for a long time, thereby affecting the health of indoor personnel.

[0040] In this embodiment, the controller has a timing module, which is used to record the interval time between the last drainage of the drainage part 5 and the present. Preferably, the timing module is a timer on the programmable logic controller. For example, the last drainage time was 9 a.m. and now it is 12 noon, then the time recorded by the timing module is 3 hours. Furthermore, a display module is provided on the controller, which can directly display the time recorded on the timing module. When the time recorded by the timing module reaches the set time, the controller 2 controls the electric control valve 3 to open, and the water replenishment tank 1 replenishes water to the water seal part 6, thereby replacing the water seal liquid at the water seal part 6. In actual use, the controller 2 is also provided with a button. When the button is started, the controller 2 can actively control the electric control valve 3 to open, thereby replenishing water to the water seal part 6 and replacing the drainage water liquid.

[0041] In this embodiment, if Figure 2~Figure 7As shown, the positioning device includes an isolation portion 23 and a lifting portion 21. The isolation portion 23 is arranged on the outer wall of the drainage portion 5. The drainage portion 5 is connected with a water seal portion 6. The isolation portion 23 extends to the water storage portion of the water seal portion 6, and a receiving cavity is also formed between the isolation portion 23 and the water seal portion 6. The lifting portion 21 is inserted into the isolation portion 23, and a positioning cavity 22 is arranged on the lifting portion 21. When the water level sensor 7 is installed in the positioning cavity 22, the positioning cavity 22 is located outside the water storage portion of the water seal portion 6, so that the water level sensor 7 is located outside the water seal portion 6. When the liquid detector 8 is installed in the positioning cavity 22, the positioning cavity 22 is located outside the water storage portion of the water seal portion 6. When the positioning cavity 22 is in place, the positioning cavity 22 is located outside the drainage portion 5, so that the liquid detector 8 is located outside the drainage portion 5. Preferably, the isolation portion 23 is a U-shaped block, and the lifting portion 21 is a U-shaped structure. Of course, in actual use, the isolation portion can be a rotating body, and the drainage portion 5 and the water seal portion 6 are both located inside the rotating body. A plug-in groove 25 is provided on the inner side wall of the isolation portion 23, and a plug-in protrusion 32 that cooperates with the plug-in groove 25 is provided on the lifting portion 21. Preferably, the plug-in groove 25 is a dovetail groove. After the plug-in protrusion 32 is engaged in the dovetail groove, radial loosening of the lifting portion 21 can be avoided.

[0042] In this embodiment, an upper cover plate 28 is installed on the top of the lifting part 21, and the upper cover plate 28 seals the top of the accommodating chamber. During installation, after the water level sensor 7 and the liquid detector 8 are installed, the upper cover plate 28 is used to seal the top of the accommodating chamber. During specific use, a sealing ring, a sealing gasket or a sealant is arranged between the upper cover plate 28 and the accommodating chamber. When the isolation part 23 is installed, a lower cover plate 27 can be arranged at the bottom of the accommodating chamber, and the lower cover plate 27 seals the bottom of the accommodating chamber. The lower cover plate 27 can be integrally formed with the isolation part 23 or integrally formed with the lifting part 21 or exist separately. When the lower cover plate 27 exists separately, the sealing method of the lower cover plate 27 is the same as that of the upper cover plate 28. The accommodating chamber is sealed by the upper cover plate 28 and the lower cover plate 27, so that waste residue and waste water can be prevented from entering the accommodating chamber, ensuring that the lifting part 21 is inserted and extracted smoothly, and ensuring that the components in the accommodating chamber are not damaged, which is convenient for construction. Furthermore, a positioning step 26 is provided on the top of the isolation portion 23, and a positioning protrusion 30 is provided on the outer wall of the lifting portion 21. The positioning protrusion 30 is blocked in the positioning step 26. When the lifting portion 21 is inserted, when the positioning protrusion 30 is blocked by the positioning step 26, it means that the lifting portion 21 has been installed in place. To facilitate the extraction of the lifting portion 21, in the present embodiment, the water level sensor 7 and the controller 2 can be electrically connected by wire or wireless. Preferably, the water level sensor 7 and the controller 2 are connected by wire. Therefore, a wire groove 29 is provided on the positioning cavity 22, and a wire outlet hole 31 is provided on the side wall of the isolation portion 23.
