This invention discloses a thermostatic valve core and a water outlet device. The thermostatic valve core includes: a base having a valve cavity and a sliding cavity; a temperature regulating component placed in the valve cavity and adapted to extend and retract along a first direction in response to water temperature to adjust the mixing ratio of hot and cold water in the valve cavity; a sliding member slidably disposed in the sliding cavity along the first direction and adapted to abut against the temperature regulating component; a first elastic member placed in the sliding cavity and abutting against the sliding member; and a second elastic member placed in the valve cavity and abutting against the temperature regulating component with a force opposing the first elastic member. The sliding member is sealed to the cavity wall of the sliding cavity, and the sliding cavity is open to the atmosphere. The thermostatic valve core using this technical solution can achieve anti-freezing and cracking function without changing its original length, and has good versatility.
