The invention is related to a hot compress autotherapy apparatus. It consists of a control box and a hot compress head which are connected by a heat-resisting wire. When power is on, and a desired temperature is set up, current flows into electro-heat body of the head through a temperature setting means and temperature control relay in the control box, and a temperature sensing unit located in a center groove in the head feeds a real-time temperature signal to the temperature setting means so that the temperature control relay can automatically be cut, to maintain a desired constant temperature between the range of setting temperature +/-1 DEG C by the hot compress head off and on. When the temperature control means is failing, an over temperature relay is off, and an alarm works to ensure safety use. |
