The passage of a cold water through the hole allows the third temperature regulating hole and the temperature control chamber to form a mutual conduction. The cap is a closed cover body with an opening facing downward, and the circumference of the ring is provided with a plurality of heats running through the cap. The water passes through the hole, and the inner ring spacer ring of the support sleeve is provided with a plurality of protruding claw portions, so that each of the two adjacent claw portions can be a water outlet passage, and the support sleeve is combined in the mixed water outlet hole of the lower seat, Providing the temperature sensor to be placed on the load by using the protruding portion of the claw portion, and the sleeve in the opening of one end of the temperature sensor has a ejector pin. Filled with a chemical substance that can be subjected to thermal expansion and contraction effects due to changes in ambient temperature, and the thermal expansion of the chemical substance enables the ram to be pushed out from the opening by the chemical substance, and After the chemical substance is cooled, it can be restored to the original volume. The water stop sleeve has a tubular body and a casing with an opening facing downward, and the casing and the tubular body are inner and outer phase sleeves, and then combined with a bottom edge, and a plurality of water-passing holes are formed in the bottom edge of the bottom edge, and the cover is provided with the one end portion of the temperature sensor having the top rod, so that the water stop sleeve can be appropriately covered In the warmer, the spring is supported between the cap and the water stop sleeve, and the water stop sleeve is pushed up in a normal state in which the top rod is retracted, so that the tubular sleeve of the water stop sleeve is The body energy is staggered to the hot water through the hole of the cap, and the hot water is not The through hole forms a shadow, and the support of the temperature sensor causes the water stop frame to be high, and the cold water passing through the hole of the water dividing member can also be prevented from being blocked by the tubular body of the water stop sleeve. The cold water passing through the hole can always be in conduction with the water outlet passage of the support sleeve.
