[0002] The thermostatic valve core currently on the market is equipped with a plunger, and the lower valve shell of the thermostatic valve core is provided with cold and hot water inlet grooves respectively. Hot water enters from the hot water inlet groove between the bottom of the plunger and the valve seat and needs to pass through the water hole of the plunger, and then flows upward. Cold water enters from the cold water inlet groove between the top of the plunger and the adjusting handwheel and directly contacts and mixes with the hot water, and then flows out from the water outlet of the upper valve shell.
[0003] After analysis, it was found that in the above-mentioned mixed water structure, the temperature sensing element of the thermostatic valve core did not have sufficient time to contact the mixed water, so the mixed water flowed out directly. Due to the insufficient mixing time, the overall product stability was insufficient and the use effect was poor. Summary of the invention

[0006] In the above-mentioned novel high-stability dual-control thermostatic valve core, filter screens are installed on the lower valve shell corresponding to the cold and hot water inlet tanks.
[0007] In the above-mentioned novel high-stability dual-control thermostatic valve core, a connecting handle is also provided inside the regulating hand wheel.
[0008] In the above-mentioned novel high-stability dual-control thermostatic valve core, an elastic member is provided between the plunger and the lower valve housing.
