     Please refer to  FIGS. 1 and 2 , which show a health care device of a first embodiment of the present invention. The health care device includes a soft water bag  1 , a control unit  2  disposed on a side of the soft water bag  1 , and a temperature control element  3  electrically connected to the control unit  2  and disposed inside the soft water bag  1 . When the control unit  2  controls the temperature control element  3 , the temperature control element  3  disposed inside the soft water bag  1  is energized to heat and control a temperature of liquid in the soft water bag  1 . 
     According to aforementioned content, the health care device uses the control unit  2  to control and drive the temperature control element  3  located in the water bag to energize for heating, when the heated soft water bag  1  is attached on a user&#39;s body part, the soft water bag  1  can perform hot compression on the attached body part, as shown in  FIG. 2 , which shows the soft water bag  1  is attached on the user&#39;s leg part as exemplary illustration. As a result, the heated soft water bag  1  can promote blood circulation and relieve fatigue and the soreness of the part. 
     The temperature control element  3  of the present invention is formed by thermal conduction film including high thermal conductive material such as copper film, aluminum film or graphite plate, and the temperature control element  3  is electrically connected to the control unit  2 , and insulation material such as a PET film or a silicon rubber is covered on the surface of the temperature control element  3  to form a layer of insulation film which is not shown in figures, so as to prevent the temperature control element  3  from contacting the liquid in the soft water bag  1  to cause short circuiting during the process of energizing to heat. The heat generated by energization can be conducted to the liquid in the soft water bag  1  through the temperature control element  3 , to increase the temperature of the soft water bag  1 . 
     The health care device can include a temperature sensor  4  disposed on a surface of the control unit  2  and electrically connected to the control unit  2 . The health care device can be energized to heat up to 45° C., and the temperature of 45° C. is set as a threshold for the high-temperature hot compression. When the temperature sensor  4  senses that the temperature reaches 45° C., the control unit  2  obtains the sensing information indicative of 45° C. and stops driving the temperature control element  3 . When the temperature sensor  4  senses that the temperature is lower than 35° C., the control unit  2  obtains the sensing information indicative of lower than 35° C. and drives the temperature control element  3  to increase temperature, so that the temperature of the soft water bag  1  can be increased up to 45° C., to remain stable hot compression effect. Besides the aforementioned manner of using the temperature sensor  4  to automatically adjust temperature, the user can use a button disposed on the surface of the control unit  2  to control temperature manually, to adjust the temperature of the soft water bag  1  to an appropriate temperature. 
     Furthermore, when the control unit  2  fails to obtain the sensing information, the control unit  2  is determined as abnormal, and the temperature control element  3  is forced to stop increasing the temperature, to prevent from damage of the temperature sensor  4  or prevent from occurring safety accident due to failure of transmitting the signal indicative of sensed temperature. 
     The soft water bag  1  of the health care device is made by plastic material such as silica gel, rubber or PVC, and the plastic property of the soft water bag  1  provides the soft water bag  1  to snugly attach with the body part. 
     The details of a second embodiment and a third embodiment are described in the following paragraphs. 
     As shown in  FIGS. 3 to 5 , the difference between the second embodiment and the first embodiment is that the soft water bag  1  of the second embodiment is in an elongate shape and includes a pasted part  11  formed on a convex side thereof, the pasted part  11  includes two eye avoidance grooves  111  recessed thereon, and when the pasted part  11  of the soft water bag  1  are attached on user&#39;s eyes, the eyes can be accommodated in the eye avoidance groove  111 , to prevent the eyes from in direct contact with the soft water bag  1  or being too close to the soft water bag  1 , thereby reducing the defective effect of hot compression on the eyes, for example, the eyes are burnt by excessively high temperature, or too high temperature causes transient blindness. Furthermore, the pasted part  11  has a certain thickness to appropriately block heat, so that the user&#39;s eye and skin surrounding the eyes can be prevented from being indirectly burned by the high-temperature liquid in the soft water bag  1 . 
     As shown in  FIGS. 6 and 7 , the difference between the third embodiment and the first embodiment is that when the soft water bag  1  includes a neckrest part  12  disposed on other side of the soft water bag opposite to the control unit  2 , so that when the soft water bag  1  is attached with the user, the soft water bag  1  can attached with the user&#39;s neck part. 
     The present invention disclosed herein has been described by means of specific embodiments. However, numerous modifications, variations and enhancements can be made thereto by those skilled in the art without departing from the spirit and scope of the disclosure set forth in the claims.
