Summary of the invention

The purpose of this utility model provides that a kind of volume is less, easy to use, induction electric weight enough electromagnetic oven wireless temperature measuring devices.

Technical solution of the present utility model is: a kind of electromagnetic oven wireless temperature measuring device, it is provided with temp probe, processes temperature signal circuit, the emitter of electrical connection in housing, and by being wound in the inductive power supply source that some circle coils on the magnetic core and rectifying and wave-filtering storage circuit are formed, the temp probe pan outer wall of can conflicting when housing is connected on the pan outer wall by stationary installation.

Inductive coil is wound on the magnetic core, can attract more magnetic fields to pass, making by the magnetic flux in the coil increases, induce higher relatively electric current, therefore whole power circuit volume is less, be convenient to install and use, made wireless temperature measuring device overall volume can be dwindled, realize miniaturization, on any position around being convenient to be installed on the pan, can obtain enough power supply supplies, temperature measurement signal is sent by emitter by stationary installation, by being used for the control of electromagnetic oven temperature after the reception of the receiving trap in the electromagnetic oven, realize accurately controlling automatically.

As a kind of prioritization scheme, be provided with insulation material layer between described stationary installation and the housing, described temp probe passes insulation material layer and conflicts on described pan outer wall.Can completely cut off the influence of temperature, improve the security and the stability of device work circuit part.

Described stationary installation is that an end is fixed on the described pan outer wall and the other end is provided with the buckling base of buckle, described insulation material layer is provided with the draw-in groove that matches with buckle, buckling base is provided with the perforate of passing described temp probe of perforation, described buckle is "T"-shaped, corresponding described draw-in groove is inverse-T-shaped, like this can be on the pan of various materials with the buckling base predetermined fixed, by the mode of pegging graft housing is fixed on the buckling base, install easily, simple to operate, can be suitable for non-magnetic pan, and temp probe contacts closely with the pan outer wall, thermometric is accurate.

Described stationary installation is the permanent magnet that is arranged on the described insulation material layer, can directly be used on the pan of magnetic conductivity, and material is easy to get, and is convenient to make.

Described stationary installation is the gum box that is arranged on the described insulation material layer, directly sticks on the pan outer wall by the high temperature resistant glue that places gum box.

Described magnetic core is that " [" type, half camber or " I " type are convenient to magnetic induction, raise the efficiency.

The utility model has the advantages that: structural volume is less, is provided with conveniently, and the induction electric weight is enough, and applicability is wide.
