[0002] A hot water circulation pump is a mechanical device that provides stable pressure and flow rate for circulating heat carriers (such as hot water). It is usually installed between the water heater and the radiator or shower to promote the rapid flow of hot water in the piping system and avoid users waiting for a long time during the heating process. The characteristics of a hot water circulation pump include compact design, simple structure, automatic start and stop function, low noise, etc.; the automatic control function of the pump can save users time and energy wasted by manually starting and shutting down the water heater; however, a hot water circulation pump cannot solve all hot water flow problems, and it also has its applicability and limitations, and users need to choose and use it according to actual conditions.

[0003] According to the hot water circulation pump in the prior art, it is found that when the existing hot water circulation pump transports high-temperature liquid, hot water and high pressure accumulate in the pipeline for a long time, which will reduce the safety of the pipeline and the pump body and may cause unexpected pressure loss and collapse. In addition, the existing hot water circulation pump usually adopts flange and other connection methods to connect the pipeline, which makes the installation operation complicated and the disassembly and inspection are also very difficult.

[0029] The monitoring chamber 301 provides a stable installation environment for the pressure sensor 302, ensuring the accuracy and reliability of pressure monitoring. The pressure sensor 302 can monitor the pressure conditions in the pump body and the pipeline in real time, and detect pressure abnormalities in time. The sealing plug rod 303 can pop out quickly during pressure relief, achieving rapid pressure relief and protecting the safety of the pump body and the pipeline. The rotating column 304 is used to adjust the position of the limiting rod 305 so that the sealing plug rod 303 can pop out when the pressure is too high to achieve pressure relief. The limiting rod 305 is used to limit the pop-up position of the sealing plug rod 303 to ensure the timeliness and effectiveness of pressure relief.

[0030] The connecting mechanism 4 also includes a mounting frame 404, a mounting rod 405, a limiting plate 406, a limiting seat 407, a spring body 408, a socket 409, a rotating shaft seat 410, a buckle rod 411 and a buckle seat 412. The upper and lower ends of the connecting tube 401 are fixedly mounted with the mounting frame 404, the upper end of the mounting frame 404 is mounted with the mounting rod 405, and the upper end of the mounting rod 405 is fixedly mounted with the limiting plate 406. The limiting plate 406 and the mounting frame 404 are in a limiting relationship.

Sockets 409 are fixedly installed on the outer walls of the upper and lower ends of the extension tube 402, and the sockets 409 are plugged with the mounting plug rod 405. A rotating shaft seat 410 is fixedly installed on the outer walls of the front and rear ends of the extension tube 402, and a buckle rod 411 is installed on the rotating shaft seat 410.

[0031] The sealing gasket 403 is used to ensure the sealing of the connection between the connecting tube 401 and the extension tube 402 to prevent hot water leakage. The installation rod 405 is used to fix the connection between the connecting tube 401 and the extension tube 402 to ensure the stability of the connection. The spring body 408 is used to push the installation rod 405 downward to achieve the plug-in effect. The socket 409 is used to receive the installation rod 405 to ensure the rapid docking of the connecting tube 401 and the extension tube 402. The snap rod 411 is used to be fixedly connected to the snap seat 412 to achieve the complete connection effect of the connecting mechanism 4.

[0032] The working principle of the utility model is as follows: the hot water circulation pump is additionally provided with a safety mechanism 3 and a connecting mechanism 4. Before using the hot water circulation pump, the pressure sensor 302 needs to be pre-connected to the power supply and connected to the control terminal. When using the hot water circulation pump, the connecting mechanism 4 is enabled. It is only necessary to insert the extension tube 402 into the connecting tube 401 to quickly connect the two. When the extension tube 402 is inserted into the connecting tube 401, the socket 409 pushes the installation plug rod 405 to move it upward. When the installation plug rod 405 is just located on the notch of the socket 409, the installation plug rod 405 is fixedly inserted into the notch of the socket 409 under the push of the spring body 408, thereby preliminarily and stably connecting the extension tube 402 and the connecting tube 401. Then, the buckle rod 411 is pulled so that the buckle rod 411 is fixedly connected to the buckle seat 412 to achieve a fully connected effect. During use, the pressure sensor 302 can monitor the pressure conditions in the pump body and the pipeline. When the pressure is too high, the user can adjust the rotating column 304 and the limiting rod 305 so that the limiting rod 305 no longer limits the sealing plug rod 303. At this time, the sealing plug rod 303 will pop out and the pump body and the pipeline will be depressurized. In summary, the safety mechanism 3 uses a sensor to monitor the pressure and sets a pressure relief structure, which realizes the monitoring of the pressure conditions in the pump body and the pipeline, which is convenient for users to adjust and control, and can also perform pressure relief operations according to the situation, thereby protecting the pump body and the pipeline and improving the safety of the pump body. The connecting mechanism 4 adopts a double-layer connecting structure, one part of which is a limiting installation structure that does not require adjustment, and the other part is a manually adjusted snap-on installation structure. On the premise of ensuring the stability and safety of the pipeline connection, quick disassembly and assembly operations can also be performed, which effectively improves the overall practicality and reliability of the pump body.
