[0021] Please see Figure 1-2 A valve body structure with equipotential function includes a lower valve body cover 1, an upper valve body cover 2, a valve body body 5, a mixing valve core assembly, and a water distribution valve core assembly.

[0022] Specifically, the lower cover 1 of the valve body is located below the main body 5 of the valve body, and the upper cover 2 of the valve body is located above the main body 5 of the valve body. The lower cover 1 and the upper cover 2 of the valve body are fixed together by snaps and threads, which limit and fix the main body 5 of the valve body.

[0023] Specifically, the valve body 5 includes a valve body injection molded part 5.1, on which a mixing valve insert 5.2, a water distribution valve insert 5.3, an equipotential insert 5.4, a red indicator ring 5.5, and a green indicator ring 5.6 are fixedly installed.

[0024] The mixing valve insert 5.2 and the water distribution valve insert 5.3 are integrally injection molded with the valve body body injection molded part 5.1. Both inserts have water passage holes and installation positioning holes on their upper end faces, and external threads for installation are provided on the upper outer side.

[0025] The equipotential bonding insert 5.4 is integrally injection molded with the valve body injection molded part 5.1. The lower end of the equipotential bonding insert 5.4 passes through the valve body injection molded part 5.1 and contacts the mixed water flow inside the valve body injection molded part 5.1, while the other end is grounded through a wire. Multiple annular grooves are provided on the outside of the equipotential bonding insert 5.4 to ensure better integral molding between the equipotential bonding insert and the valve body injection molded part, preventing the equipotential bonding insert from falling off after molding and avoiding leakage due to the connection between the two. A countersunk hole with an internal thread is provided on the equipotential bonding insert 5.4 to facilitate the installation of wires through threaded components.

[0026] The red indicator ring 5.6 and the blue indicator ring 5.5 are welded to the valve body body 5 via secondary injection molding, indicating that the two ports of the valve body are suitable for hot water and cold water.

[0027] Specifically, the mixing valve core assembly includes a mixing valve core 6, a mixing valve core fixing cap 4, and a mixing valve core fixing sleeve 8.

[0028] The mixing valve core 6 is used to mix cold water and hot water in appropriate amounts according to the valve core opening to form mixed water of different temperatures. The mixing valve core 6 is positioned on the mixing valve insert 5.2. The mixing valve core fixing sleeve 8 is placed on the outside of the mixing valve core 6. It has an internal thread and its lower end is threaded and fixed on the mixing valve insert 5.2. The outer end of the mixing valve core fixing cap 4 has an external thread. Its thread is screwed and fixed on the upper part of the mixing valve core fixing sleeve 8, and squeezes and limits the mixing valve core 6.

[0029] During installation, first position the mixing valve core 6 on the mixing valve insert 5.2, then fix the lower end of the mixing valve core fixing sleeve 8 on the mixing valve insert 5.2, and screw the mixing valve core fixing cap 4 into the designated position from the upper end of the mixing valve core fixing sleeve 8 to squeeze and limit the mixing valve core 6.

[0030] Specifically, the water distribution valve core assembly includes a water distribution valve core 7, a water distribution valve core fixing cap 3, and a water distribution valve core fixing sleeve 9.

[0031] The water distribution valve core 7 is used to guide the mixed water through the valve core switch and valve core passage into different outlets, forming a switch between water outlet points / water outlet functions. The water distribution valve core 7 is positioned on the water distribution valve insert 5.3. The water distribution valve core fixing sleeve 9 is placed on the outside of the water distribution valve core 7. It has an internal thread and its lower end is threaded and fixed on the water distribution valve insert 5.3. The outer end of the water distribution valve core fixing cap 3 has an external thread. Its thread is screwed and fixed on the upper part of the water distribution valve core fixing sleeve 9, and squeezes and limits the water distribution valve core 7.

[0032] During installation, first position the water distribution valve core 7 on the water distribution valve insert 5.3, then fix the lower end of the water distribution valve core fixing sleeve 9 on the water distribution valve insert 5.3, and screw the water distribution valve core fixing cap 3 into the designated position from the upper end of the water valve core fixing sleeve 9 to squeeze and limit the water distribution valve core 7.

[0033] Specifically, the valve body cover 2 is secured with a mixing valve core protective cover 10 and a water distribution valve core protective cover, which are used to protect the mixing valve core 6 and the water distribution valve core 7, respectively.

[0034] The working process of the valve body of this utility model is as follows:

[0035] When cold and hot water enter the valve body, the mixing valve core 6 mixes the cold and hot water in appropriate amounts according to the valve core opening to form mixed water of different temperatures. The water distribution valve core 7 guides the mixed water through the valve core switch and valve core passage to different outlets, forming a switch between water outlet points / water outlet functions. During normal use, the internal water flows through the flow channel and simultaneously contacts the equipotential insert 5.4. If there is a risk of leakage, the current in the water flow will preferentially contact the conductive copper insert (i.e., the equipotential insert 5.4) and guide the current to the outside ground, preventing the water flow from carrying current at the outlet position and preventing electric shock.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
