cold water and hot water enter the top and the bottom of the plunger 50 from the cold water inlet 201 and the hot water inlet 202 of the lower shell 20 respectively, and flow through the cold water inlet notch 203 between the plunger 50 and the upper shell 10 and the hot water inlet notch 204 between the plunger 50 and the lower shell 20 respectively, the plunger 50 moves upwards or downwards to adjust the sizes of the cold water inlet notch 203 and the hot water inlet notch 204, so that the sizes of the cold water inflow and the hot water inflow are realized, the cold water flows into the temperature sensing area of the paraffin temperature package 60 from the inside of the plunger 50 and then is mixed with the hot water, the plunger 50 is driven to move by the characteristics of heat and cold shrinkage of the paraffin temperature package 60 to realize temperature self-adjustment, and when the spline bar 30 is released, the plunger 50 is driven by the working spring 70 between the plunger 50 and the lower shell 20, and the existing temperature control valve core has the following defects:
1. at present, the temperature control valve core plunger 50 on the market is designed into an integral structure, and is used in a region where water quality contains sediment, the plunger 50 is blocked due to the sediment problem, so that the temperature control valve core cannot be used, and a filter screen 80 is often required to be sleeved on the lower shell 20 to prevent sediment from blocking the valve core, but the filter screen is difficult to block tiny sediment from entering.
2. The protection springs of the constant-temperature valve core for adjusting the water temperature by adopting the paraffin wax temperature pack 60 on the market are designed inside the guide rod (belonging to the screw tooth transmission assembly 30), and the constant-temperature valve core cannot be assisted in impurity removal treatment in the use process.
