Problems solved by technology

[0009] However, figure 2 The thermostatic spool shown still has the problem that rotation of the spindle 130 causes the sensor bracket 181 to move, and movement of the sensor bracket 181 causes the first o-ring 191 to move with it
[0011] Thus, the change in vacuum between the first O-ring 191 and the second O-ring 192 allows water to gradually seep through the first O-ring 191 and into the helical coupling region C between the spindle 130 and the sensor holder 181 , thereby forming impurities or rust in the helical coupling region C, making the main shaft 130 not rotate smoothly and becoming stiff

Abstract

The object of the present invention is to provide a thermostatic spool with a simple and efficient structure for preventing the influx of water into the area of ​​the screw coupling between the spindle and the sensor holder, thereby preventing the entry of impurities or rust in this area and effectively To prevent the phenomenon that the spindle operation is interrupted.

Description

technical field [0001] The present invention relates to a thermostatic spool, and more particularly to a thermostatic spool with a simple and efficient structure for preventing water from rushing into the helical coupling area between the main shaft and the sensor bracket, thereby preventing the area from entering impurities or Generates rust and effectively prevents the spindle from being interrupted. Background technique [0002] A thermostatic spool is a device that automatically controls the flow or variable of hot and cold water introduced into it in order to maintain a constant temperature for the initial setting of the mixed water. The thermostatic spool can be used for faucets, etc. [0003] Typically, the wax-type thermostatic valve core is the most widely used, and the valve in it works according to the characteristics of wax expansion and contraction. [0004] figure 1 The thermostatic spool shown has a mechanism where wax filled inside senses changes in temper...
