Description:
FIELD OF THE INVENTION  
      The present invention relates to sap adjusters, and particular to a sap adjuster which includes a plurality of hot compress units arranged in parallel and the plurality of hot compress units are enclosed by two large area heat-tolerable insulting rubber sheets so as to have a larger hot compress area.  
     BACKGROUND OF THE INVENTION  
      The prior art health machine frequently uses electromagnetic waves or electric pulses as a means for treat. However, impulses are easily generated and the stability is thus low. Thereby, these kinds of prior arts are not so suitable. The inventor of the present invention ever designs a hot compress treating machine which includes a hot compress head, a temperature sensor, and a control box. The hot compress head is a rectangular insulator body. A front face thereof has a shallow and a deep recesses. Two sides of the recesses are installed the two electric heated sheets. Each electric heated sheet has two threaded holes. A short conductive wire serves to connect the two electric heated sheets. The power wires pass through the screw holes of the electric heated sheets to be connected to the outer terminals of the two electric heated sheets. The temperature sensors are placed in a long recess of an insulating body. The power wires of the temperature sensors and the electric heated sheets and the shielding conductive wire at one end of the temperature sensor pass through the threaded holes of the insulating body. A bottom plate is a rectangular plate. An upper side thereof has four threaded holes. Four screws serve to fix the bottom plate to the shallow recess of the insulating body. One threaded hole of the insulating body is installed with a joint. Another end thereof is engaged with a soft tube. The power wire, i.e., a shield conductive wire passes through the soft tube to a backside of the control box for connecting the indicators and temperature setting device. Furthermore, a cloth cover encloses the hot compress head. The backside of the control box is further connected to a power plug and a soft conducive tube and a front side thereof is installed with a power switch, a temperature controller, a current meter, and an indicator. The temperature controller includes a temperature setting device and a number display. A hold type fuse is connected between the power switch and a temperature setting device. The temperature setting device is further connected to a temperature controlling relay, and then is connected to the current meter and the indicator. The indicator is connected to the electric heated sheets of the hot compress head. The temperature setting device is connected to an overheat protecting circuit. The overheat protecting circuit is connected to an abnormal alarm device.  
      However, the prior art still has some defects which will be described here.  
      Firstly, the hot compress head is a rectangular insulating body. Four threaded holes are used in connection. Thereby, the connection is a hard-connection. When it is necessary to hot compress the back of the patient, the user will feel uneasy. Thereby, the curved portion of the body cannot suit the structure of the hot compress head. Thereby, the treating effect is not preferred.  
      Secondary, as shown in  FIG. 1 , the prior art hot compress way for a larger hot compress area is illustrated. When a larger area is necessary to hot compress, a plurality of hot compress heads  6  are assembled for achieving a desired effect. Thereby, some bandages  4  are needed to fix the hot compress heads. However, the fixing way is unstable. If the body of the patient moves, the user will feel inconvenient.  
      Thirdly, when more and more hot compress heads  6  are used, the power wires will wind complicatedly. If it is desired to separate the wires in force, the power wires will destroy so that power will lose.  
      Fourthly, a handle is added to the hot compress head for being held by the user, but the user is easy to hurt due t the heat from the hot compress sheets. Thereby, this prior art device is easy to use to hot compress a small area.  
     SUMMARY OF THE INVENTION  
      Accordingly, the primary object of the present invention is to provide a sap adjuster comprises a plurality of hot compress units and a control box. Each hot compress unit has a heat-tolerable insulting rubber sheet and two electric heated sheets. The heat-tolerable insulting rubber sheet and the two electric heated sheet are combined by silicon. A short conductive wire serves to connect the two electric heated sheets. Each electric heated sheet being connected with a long conductive wire. Thereby, the sap adjuster is suitable to the curvature of human body. The sap adjuster of the present invention can be used with a cushion, pillow or mattress. Thereby, the use of the sap adjuster is not confined by positions and timings.  
      Another object of the present invention is to provide a sap adjuster, wherein a plurality of hot compress units are connected in parallel so as to be formed as a large area heat-tolerable insulting rubber sheet. The long conductive wires of electric heated sheets are collected at the edges of the large area heat-tolerable insulting rubber sheet. The upper sides and lower sides of the plurality of hot compress units are enclosed by two large area heat-tolerable insulting rubber sheets so that the whole sap adjuster of the present invention can be bent with the shape of the human body. Thus, the present invention is a device of matching ergonomics.  
      Moreover, in the present invention the power wires are arranged in order so that the power wires are not wound complicatedly.  
      The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.
