  This must also be provided with its own heating. This is also true for the embodiments described in

US-A-851,510 and US-A-4,427,001.

  The object of the invention is to combine a heat treatment with

  with a massage treatment to deepen and accelerate the effect, and ensure a regular distribution of heat in the treatment head, in which case this head

  treatment must be interchangeable.

  This is achieved, according to the invention, because the treatment head is made of a heat conducting material and has a heat conducting rod which

  engages inside the handle and the fact that the disc

  positive heating element mounted inside the handle, in an intermediate position with respect to the vibrating or eccentric drive member, is associated with the stem of the heat treatment head or a fixation of the rod to the inside the handle The treatment head, including the stem, is made of a material that is a good conductor of heat, for example chrome-plated brass, shaped and free of electrical equipment.

  The heater is located in the handle, which allows

  The treatment head can be economically reduced, and it can also be effectively cleaned using an agent in liquid solution without the risk of a short circuit. Thanks to the heating device in the shaft area , a regular distribution of heat over the entire treatment head The heat released by the electrical drive member during its operation, and which can then represent a significant heat loss power, is transmitted by thermal conduction bridges to the stem or rod holder The intensity setting can relate to the heating power, the stroke and also the frequency

of vibrations.

  According to another embodiment of the invention, the

  stem has a cavity and the heating device

  especially in the form of a semi-conductor

  The circuit can be made in such a way that, when a certain amount of heat has been reached, the heating power is temporarily reduced, until it has been exceeded. a certain thermal transmission gradient with respect to the head of the treatment head which indicates a capacitance
