[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] Referring to FIG. 1 to FIG. 6 , a water trap water replenishment system provided in the present application includes:

[0050] A shell body 1, wherein a three-way pipe 2 is arranged inside the shell body 1, and the three-way pipe 2 is provided with a water inlet 21, a first drain outlet 22 and a second drain outlet 23 which are interconnected; a water inlet pipe 3, wherein one end of the water inlet pipe 3 is connected to the water inlet 21, and the other end is connected to a water delivery pipeline 31; a first water outlet pipe 4, wherein one end of the first water outlet pipe 4 is connected to the first drain outlet 22, and the other end is connected to an input pipe 42 of a water trap 41; a second water outlet pipe 5, wherein the second water outlet pipe 5 is connected to the second drain outlet 23; a valve assembly, wherein the valve assembly is arranged inside the three-way pipe 2, and the valve assembly controls the first water outlet pipe 4 to connect or disconnect the water inlet pipe 3 and the second water outlet pipe 5 accordingly; and a controller, wherein a signal connection is established between the controller and the valve assembly.

[0051] That is to say, a three-way pipe 2 is installed inside the shell 1, and the three-way pipe 2 has three interconnected interfaces: a water inlet 21, a first drain outlet 22, and a second drain outlet 23. These three interfaces respectively bear different water flow guiding functions. The water inlet pipe 3 is the input end of the system, and one end of it is tightly connected to the water inlet 21 of the three-way pipe 2 to ensure that the water source can enter smoothly. The other end is connected to the water supply pipeline 31, which is responsible for extracting water from an external water source (such as a tap water pipeline) for supply to the system. One end of the first water outlet pipe 4 is connected to the first drain outlet 22 of the three-way pipe 2, and the other end is connected to the input pipe 42 of the water trap 41. Through the first water outlet pipe 4, the system can guide the water flow to the water trap 41, thereby maintaining the stability of the water level inside it, avoiding the water in the water trap from gradually decreasing due to evaporation, resulting in too low a water level, and effectively preventing the generation of odor. One end of the second water outlet pipe 5 is connected to the second drain port 23 of the tee pipe 2, and the other end can be connected according to actual needs, such as connected to other drainage pipes or equipment. The valve assembly is installed inside the tee pipe 2. Through its opening and closing action, the first water outlet pipe 4 can be controlled to connect or disconnect the water inlet pipe 3 and the second water outlet pipe 5 accordingly. That is to say, the system is also equipped with a controller, which establishes a signal connection with the valve assembly and can accurately control the opening and closing action of the valve assembly according to a preset program or external instructions. The controller can automatically start the water replenishment program according to a preset time interval (such as every 5 days or 10 days). During the water replenishment process, the controller first connects the first water outlet pipe 4 with the water inlet pipe 3 through the valve assembly, allowing water to flow from the water inlet pipe 3 into the water trap 41 for water replenishment. This operation ensures that the amount of water in the water trap is always maintained at an appropriate level, thereby ensuring the integrity of the water seal.

[0052] When the water replenishment process lasts for a certain period of time (such as 10 minutes or 20 minutes), the controller will control the valve assembly again to disconnect the first water outlet pipe 4 from the water inlet pipe 3 and connect the second water outlet pipe 5. This operation discharges the remaining water in the first water outlet pipe 4, releases the pipeline pressure, and prevents the remaining water in the pipe from deteriorating or depositing dirt.

[0053] In addition, the water trap water replenishment system also allows users to easily set the system's operating mode through the controller. Users can adjust parameters such as the water replenishment time interval, water replenishment duration, and drainage duration according to their needs and actual conditions to achieve personalized control and management. This flexibility enables the system to adapt to a variety of application scenarios and environmental conditions.

[0054] In summary, the water trap replenishment system provided in the present application can replenish water to the water trap at a regular interval to maintain the integrity of the water seal, thereby effectively preventing odor and harmful gases in the sewer pipe from overflowing.

[0055] Referring to Figures 2-5 and Figure 8, based on the above embodiments, the valve assembly includes a valve ball 6 and an actuator connected to the valve ball 6. The valve ball 6 is arranged in the cavity of the three-way pipe 2. The valve ball 6 is provided with a first opening 61, a second opening 62 and a third opening 63 that are interconnected. The first opening 61 and the second opening 62 are arranged opposite to each other. The actuator establishes a signal connection with the controller to control the valve ball 6 to be in the first working position or the second working position. When the valve ball 6 is in the open state, the water inlet pipe 3 is connected to the first water outlet pipe 4. When the valve ball 6 is in the second working position, the first water outlet pipe 4 is connected to the second water outlet pipe 5.

[0056] That is, the valve ball 6 is installed in the cavity of the three-way pipe 2, and the valve ball 6 is provided with three interconnected openings: a first opening 61, a second opening 62 and a third opening 63. The actuator establishes a signal connection with the controller, receives instructions from the controller and converts them into mechanical actions. According to the instructions of the controller, the actuator can accurately control the rotation of the valve ball 6 to place it in different working positions.

[0057] When the system needs to replenish water to the water trap 41, the controller will send a command to the actuator to put the valve ball 6 in the first working position, as shown in Figure 4. In the first working position, the first opening 61 of the valve ball 6 is connected to the water inlet 21 of the tee pipe 2, and the second opening 62 is connected to the first drain port 22, while the third opening 63 is in a closed state with the inner wall of the top tee pipe 2. In this way, the water flow in the water inlet pipe 3 can smoothly enter the tee pipe 2 through the water inlet 21, and flow to the first water outlet pipe 4 through the first opening 61 and the second opening 62 of the valve ball 6, and finally enter the water trap 41 for water replenishment.

[0058] When the water replenishment is completed, the controller will send a command to the actuator again to rotate the valve ball 6 from the first working position to the second working position, as shown in Figure 5. In the second working position, the second opening 62 of the valve ball 6 is disconnected from the first drain port 22 and then communicated with the second drain port 23, while the third opening 63 is connected to the second drain port 23, and the rear end of the valve ball 6 blocks the water inlet 21. In this way, the remaining water in the first water outlet pipe 4 can flow into the second water outlet pipe 5 through the third opening 63 of the valve ball 6 and the second drain port 23, and finally be discharged from the system, thereby releasing the pipeline pressure, preventing the remaining water in the pipe from deteriorating or depositing dirt, and ensuring the quality of the water for the next water replenishment.

[0059] On the basis of the above embodiment, an automatic valve is provided on the water pipeline 31, and a signal connection is established between the automatic valve and the controller, that is, an automatic valve is specially provided on the water pipeline 31, and a signal connection is established between the automatic valve and the controller, so that the system can be automatically regulated according to a preset program or external instruction. Specifically, when the water trap 41 needs to be replenished with water, the controller will send an opening instruction to the automatic valve to open the automatic valve, allowing water to enter the water pipeline 31 and flow to the water trap 41. When the water replenishment is completed, the controller will send a closing instruction to the automatic valve to close the automatic valve, cut off the water source, and ensure that the system is in a safe and stable state.

[0060] Referring to Fig. 3, Fig. 6, Fig. 8 and Fig. 9, the actuator includes a motor 7 and a transmission rod 71. A motor mounting seat 24 is provided on the outside of the three-way pipe 2. A through hole 25 is provided in the middle of the motor mounting seat 24. The through hole 25 is used to install the transmission rod 71. The valve ball 6 is provided with a card slot 64. One end of the transmission rod 71 is connected to the output end of the motor 7, and the other end is matched and connected with the card slot 64. A groove 711 is provided on the outer peripheral surface of the transmission rod 71. The groove 711 is used to install an O-ring.

[0061] That is to say, the actuator mainly includes a motor 7 and a transmission rod 71. First, a motor mounting seat 24 is provided on the outer side of the three-way pipe 2, and a through hole 25 is provided in the middle. The main function of the through hole 25 is to allow the transmission rod 71 to pass through so as to connect the motor 7 and the valve ball 6. One end of the transmission rod 71 is tightly connected with the output end of the motor 7 to ensure that the rotational force of the motor 7 can be accurately transmitted to the transmission rod 71. The other end is matched and connected with the slot 64 on the valve ball 6, so that when the motor 7 rotates, the transmission rod 71 can drive the valve ball 6 to perform a corresponding rotation action. In order to ensure the stable rotation of the transmission rod 71 in the through hole 25 and prevent water from leaking through the through hole 25, a groove 711 is provided on the outer peripheral surface of the transmission rod 71. The function of this groove 711 is to install an O-ring. The O-ring has good sealing performance and can ensure that the transmission rod 71 will not cause water leakage during rotation, thereby ensuring the safe and stable operation of the system.

[0062] In the above embodiment, the number of the grooves 711 is at least two, thereby ensuring all-round sealing of the transmission rod 71 in the through hole 25. When the transmission rod 71 rotates in the through hole 25, the O-rings on the plurality of grooves 711 can form a continuous sealing ring, effectively preventing water from leaking through any tiny gap between the transmission rod 71 and the through hole 25.

[0063] 2 , the actuator further includes an energy source 72, specifically, the energy source 72 is a battery, the energy source 72 is disposed at the bottom of the housing 1, and the energy source 72 is electrically connected to the motor 7. A detachably connected cover 11 is disposed on the top of the housing 1, an electric control compartment 12 is disposed in the cover 11, and a controller is disposed in the electric control compartment 12, specifically, the controller is a single chip microcomputer or a PLC.

[0064] That is to say, the actuator includes an energy source 72. Specifically, the energy source 72 is a battery. The battery is placed at the bottom of the housing 1. At the same time, the battery is directly electrically connected to the motor 7 to provide the motor with the required electrical energy to drive it to work. A detachable cover 11 is provided on the top of the housing 1. In order to facilitate the user's inspection and maintenance of the internal components of the system, an electric control compartment 12 is provided inside the cover 11. The controller is located in the electric control compartment 12. The controller is responsible for receiving instructions from the user or sensor and controlling the operation of the motor 7. In terms of the selection of the controller, the system uses a single-chip microcomputer or a PLC as the core control unit. Both controllers have powerful data processing capabilities and stable control performance, which can ensure that the system can operate stably in various environments.

[0065] Referring to Figures 2, 10 and 11, a first annular groove 32 is provided on the inner wall of the opening where the water inlet pipe 3 is connected to the water inlet 21, a second annular groove is provided in the cavity of the tee pipe 2, and a third annular groove 51 is provided on the inner wall of the opening where the second water outlet pipe 5 is connected to the second drain outlet 23. The first annular groove 32, the second annular groove and the third annular groove 51 are all used to install sealing rings and valve ball gaskets 65, and each valve ball gasket 65 is in contact with the outer circumferential surface of the valve ball 6.

[0066] That is to say, a first annular groove 32 is provided on the inner wall of the opening of the water inlet pipe 3, a second annular groove is provided in the cavity of the tee pipe 2, and a third annular groove 51 is provided on the inner wall of the opening of the second water outlet pipe 5, all of which are used to install a sealing ring and a valve ball gasket 65. The valve ball gasket 65 fits tightly on the outer peripheral surface of the valve ball 6 to form an effective sealing layer to prevent water from leaking from the connection. In summary, by providing the first annular groove 32, the second annular groove and the third annular groove 51 at the key connection points of the water inlet pipe 3, the tee pipe 2 and the second water outlet pipe 5, and installing the sealing ring and the valve ball gasket 65, the water trap water replenishment system achieves a close connection and effective sealing between the various components. This structure not only enhances the sealing performance of the system, but also ensures the stability and reliability of the system operation, providing users with a safer and more reliable water replenishment experience.

[0067] As shown in FIG1 , the other end of the first water outlet pipe 4 is connected to a plurality of branch pipes. Since the first water outlet pipe 4 can be connected to a plurality of branch pipes, the system can be easily expanded to a plurality of water traps 41 to meet a wider range or a greater number of water replenishment needs. It can ensure that each water trap 41 can obtain sufficient water, and a control valve can be set on each branch pipe to facilitate maintenance.

[0068] 2 and 12 , a flow meter 8 is provided in the three-way pipe 2 , and a signal connection is established between the flow meter 8 and the controller to achieve quantitative water replenishment. A limiter 81 is provided in the three-way pipe 2 to limit the lateral movement of the flow meter 8 .

[0069] Specifically, a flow meter 8 is provided inside the three-way pipe 2. By establishing a signal connection with the controller, the flow meter 8 can transmit the real-time monitored flow data to the controller. The controller analyzes and processes the data transmitted by the flow meter 8 according to the preset water replenishment demand or the parameters set by the user, thereby realizing precise control of the water replenishment process. A limiter 81 is also provided inside the three-way pipe 2 to limit the lateral movement of the flow meter 8 and prevent it from being displaced or shaken under the influence of factors such as water flow impact or system vibration.

[0070] Specifically, the limiting member 81 is a pipe insert, and an annular groove for accommodating an O-ring is provided on the outer peripheral surface of the limiting member 81 to play a sealing role.

[0071] Referring to Figures 2 and 7, a connecting seat 26 is provided on the outer peripheral surface of the three-way pipe 2, and a transfer hole 27 connected to the cavity of the three-way pipe 2 is provided at the bottom of the connecting seat 26. The connecting seat 26 is used for detachably connecting the temperature and pressure sensor 9. The temperature and pressure sensor 9 establishes a signal connection with the controller, and the temperature sensor can monitor the pressure and temperature of the three-way pipe 2 through the transfer hole.

[0072] That is to say, a connection seat 26 is provided on the outer peripheral surface of the three-way pipe 2, and the connection seat 26 is used for detachably connecting the temperature and pressure sensor 9. The temperature and pressure sensor 9 is a sensor that can monitor temperature and pressure at the same time. It can be easily installed and removed by closely matching with the connection seat 26. The bottom of the connection seat 26 is provided with a transfer hole 27 connected to the cavity of the three-way pipe 2. The transfer hole 27 is a bridge between the connection seat 26 and the internal cavity of the three-way pipe 2, which allows the internal water flow, pressure or temperature and other parameters to be transmitted to the temperature and pressure sensor 9 through the connection seat. The temperature and pressure sensor 9 establishes a signal connection with the controller, and can transmit the monitored temperature and pressure data to the controller in real time.

[0073] Specifically, when the temperature and pressure sensor 9 detects that the temperature is too low or there is a risk of water leakage, it transmits information to the controller. The controller controls the valve ball 6 to rotate to the second working position, and the remaining water in the first water outlet pipe 4 can be discharged to the storage water tank through the second water outlet pipe 5, which can release the pressure in the pipeline and reduce water leakage losses.

[0074] Based on the above embodiment, the connection method between the water inlet pipe 3 and the tee pipe 2 is a threaded connection, the connection method between the second water outlet pipe 5 and the tee pipe 2 is a threaded connection, and an installation groove is provided at the bottom of the second water outlet pipe 5 to facilitate connection with the shell 1.

[0075] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
