  By the way, in the normal thermal health device, heaters are installed in each of the outer cover and inner cover of the telescoping cover, and when the outer cover is stacked on the inner cover when not in use, the heater of the outer cover becomes the inner cover. It is arranged near the outer surface. Therefore, if the heater is accidentally forgotten to be turned off, there is a risk that the inner cover is heated by the heater of the outer cover and the inner cover is burned.

  The present invention is proposed in view of the above problems, and when the heater of the outer cover is overlapped on the inner cover, the heater of the outer cover can be automatically switched off. An object of the present invention is to provide a thermal health device capable of preventing the inner cover from being heated by the heater and the inner cover from being burned by the heating.

And slide one or the other slide rail so that the magnet switch and the elongated plate come close to the position where the elongated plate attracts or repels the magnet of the magnet switch, and the magnet switch is turned on or off. It is characterized by doing. The switching mechanism can be used for various devices and instruments other than the thermal health device.

  Also, the switching mechanism of the present invention pivotally supports a lever provided with a magnet at a substantially front portion such as the front end at a substantially rear portion behind the center, and the rear end of the lever is near the upper side of a detection button such as an operation button or the like. It is arranged near the lower part, and the rear end of the lever pushes the detection button by bringing the ferromagnetic body or diamagnetic body and the magnet of the lever close to a position where they are attracted or repelled. In the above configuration, the lever rear end (operating point) has a large force for pressing the detection button and a force for maintaining the contact state according to the principle of the lever. For example, when switching the energization, even when the current is large, OFF control can be performed.

The slide rail 8 of the outer cover 2 is disposed on the outer side of the outer cover 2 at a position where the slide rail 8 substantially engages in a substantially bowl shape in cross section through a slight gap of about 2 mm, for example.

  The regions that can contact each other, such as the generally bowl-shaped portions of the slide rails 8 and 9, have surfaces with low frictional resistance, such as applying varnish to the slide rails 8 and 9 made of wood, and the outside. The contact area of the bottom surface 82 of the slide rail 8 of the cover 2 and the upper surface 121 of the guide rail 12 also has a surface with a low frictional resistance, such as a material with a low frictional resistance or a surface treatment that reduces the frictional resistance. Ensures smooth sliding in the axial direction.

  As shown in FIGS. 1 to 3, the magnet switch 10 is provided at a location that substantially corresponds to the rear end of the heater 6a and a location that substantially corresponds to the rear end of the heater 6b. The energization ON / OFF control of 6a, and the magnet switch 10 positioned substantially at the rear, are responsible for the energization ON / OFF control of the heater 6b.
