Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the application.It should be understood that this place is retouched
The specific embodiment stated is only used for describing and explaining the application, is not intended to limit this application.
Fig. 1 is the block diagram for the magnetic control knob that a kind of embodiment of the application provides.As shown in Figure 1, the application embodiment
A kind of magnetic control knob is provided, which can be used for controlling electrical equipment.The magnetic control knob 10 may include
Wireless charging receiving module 11 and power supply module 12, wherein the wireless charging of wireless charging receiving module 11 and electrical equipment emits
Module 21 is wirelessly electrically connected, and the wireless charging receiving module 11 is for receiving the wireless charging transmitting module from electrical equipment
The electric energy of 21 transmission.Power supply module 12 is connect with wireless charging receiving module 11, and the power supply module 12 is for connecing wireless charging
The electric energy that the received electric energy of module 11 is converted to DC low-voltage is received, to power to magnetic control knob 10.
In general, being to pass through electromagnetic induction principle between wireless charging receiving module 11 and wireless charging transmitting module 21
The transmission of electric energy is carried out, so the electric energy that wireless charging receiving module 11 exports is generally high-frequency alternating current, power supply module 12
Effect be the high-frequency alternating current for exporting wireless charging receiving module 11 be converted to can other consuming components directly power
DC low-voltage electricity, therefore power supply module 12 can include according to the design needs rectification circuit, voltage regulator circuit, transforming circuit and/or
Filter circuit etc..
Wherein, the electrical equipment can be any electrical equipment that can be adapted to carry out knob-operated, such as electromagnetism
Furnace, micro-wave oven and gas-cooker etc..

The electric energy of 11 outputs is directly powered after power supply module 12 is converted to direct current for other consuming components, and another kind is confession
It include energy-storage units in electric module 12, the electric energy that wireless charging receiving module 11 exports can be to energy storage after being converted into direct current
Unit charging, then by energy-storage units be other electron component power, the latter one when in use, be not necessarily to pass through wireless charging mode
It powers in real time for magnetic control knob 10, it is only necessary to just be energy storage list by wireless charging mode in the case where energy-storage units electricity is low
Member charging and/or other electron component power supply.
In a particular application, detect magnetic control knob rotation status implementation may include using Hall effect principle or
Using optical principle etc..Specifically, it if using Hall effect principle, needs on the operation circuit plate of electrical equipment and magnetic
It controls and Hall element is set in knob body, feature operation is realized by communication between the two, if decision content between the two
Changed, then knows that magnetic control knob is rotated, which can be converted into the specific angle value of rotation.If adopted
With optical principle, then need that optical transmitting set and light is arranged on the operation circuit plate of electrical equipment and in magnetic control knob body respectively
Optical signal is converted into electric signal to realize communication, if optical receiver receives the optical signal of transmitter, then knows knob by receiver
It is rotated, likewise it is possible to convert optical signal into the specific angle value of rotation.
However, above two scheme has certain disadvantages, for example, by using Hall effect principle scheme the shortcomings that be to need
Increase special peripheral circuit, cost is relatively high.And use the scheme of optical principle that there is the spot being easy by operation panel
It influences the propagation and reception of light (stop) and fails and the disadvantages of the cost is relatively high.Also, no matter magnetic control knob is using suddenly
That effect or optical principle, all there are certain requirements the thickness of magnetic control knob, since the magnetic control knob of both the above scheme is thick
Degree is too thick, therefore also affects the beauty of product to a certain extent.
