Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The utility model may be embodied in many other forms than described herein and similarly practiced by those skilled in the art without departing from the spirit or scope of the utility model, which is therefore not limited to the specific embodiments disclosed below.
Example 1
As shown in fig. 1 and 2, a waterproof and scale-proof constant temperature valve core is formed by connecting a temperature adjusting component with the top end of a shell 1 in a threaded manner, wherein the temperature adjusting component comprises a handle 2, a handle seat 3, a stud connecting piece 4, a stud 5, a stud spring 6 and a jacking column 7. The handle seat 3 is in threaded connection with the top end of the shell 1, the handle 2 is in rotary connection with the top end of the handle seat 3, and the lower part of the handle 2 is inserted into the handle seat 3. The stud connecting piece 4 is in threaded connection with the outer wall of the lower part of the handle 2, the stud 5 is arranged in the inner cavity of the bottom of the handle 2, and the stud spring 6 and the jacking column 7 are arranged in the inner cavity of the stud 5 from inside to outside.
