Description
Technical field
The utility model relates to a kind of coffee machine container material detecting sensor.
Background technology
The Sheng coffee container of coffee machine special use generally has two kinds, be respectively glass container and not with the stainless steel cool-bag of inner bag, to glass container, because it does not have heat insulation function, the reply container was incubated heating after machine performed coffee, and to rustless steel container, because itself have heat insulation function, machine should not heat container.At present, at two kinds of coffee containers, coffee machine on the market is different designs in addition usually, promptly be designed to glass container type and rustless steel container type, the container of two kinds of machines can not be general, otherwise, the phenomenon that the meeting appearance is heated rustless steel container, not only cause the electricity consumption waste, and, also there is potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of coffee machine container material detecting sensor.
The purpose of this utility model is achieved in that
The utility model comprises on-off circuit, sample circuit and the comparator that is attached thereto, and it is characterized in that: compose in parallel resonance circuit by opening inductance and electric capacity, export at the different train of pulse of glass container and rustless steel container and through comparator in order to produce.
Described inductance is formed around corresponding enamel-covered wire by silicon steel sheet or other high permeability material of E type or U type.
Described on-off circuit comprises the switching tube that is made of triode, and the colelctor electrode of this switching tube connects the resonance circuit that is composed in parallel by opening inductance and electric capacity, and the other end of described antiresonant circuit connects a current-limiting resistance.
Described on-off circuit makes the switching tube conducting in order to switching pulse to be provided by its basis set is applied high level pulse.
Described sample circuit is to be made up of resistor network, and this resistor network connects resonance circuit and the on-off circuit that is composed in parallel by inductance and electric capacity respectively, and links to each other with comparator.
Because the utility model has adopted technique scheme, promptly composes in parallel the LC oscillating circuit with inductance and electric capacity, when to this power on circuitry, the circuit storage power; When galvanization finishes, will in this LC oscillating circuit, produce and excite vibration; When circuit oscillation, opening part will excite magnetic field; When the opening part container was glass container, because its magnetic conductivity is very low, the magnetic circuit magnetic resistance that the E type of inductance or U section bar material and container constitute was very big.The little energy of internal loss cycle of oscillation, thus continue long duration of oscillation; And when opening part has rustless steel container, because the energy that stainless magnetic conductivity magnetic resistance very high, magnetic circuit reduces greatly, rustless steel container bottom will absorb considerable energy, internal loss cycle of oscillation increases greatly, the energy in LC loop exhausts very soon, vibrates very fast disappearance.Differentiate rustless steel container or glass container by the wave number of oscillation circuit, not only can guarantee to differentiate automatically the kind of container, simultaneously, all right saves energy, and raising security, the utility model can use at coffee machine and other and use the occasion of insulation heating, has vast potential for future development.
