Detailed description of the invention
Below in conjunction with accompanying drawing, detailed introduction is done to the present invention: as shown in accompanying drawing 1 to 3, the present invention mainly comprises main frame 1, power panel 2, wind deflector 3 and keypad 6, described keypad 6 is arranged in wind deflector 3 in the heart, power panel 2 is positioned on main frame 1, is disposed with hook connecting connection mechanism 4 and magnetic connecting mechanism 5 between main frame 1 and wind deflector 3 from top to bottom; Described hook connecting connection mechanism 4 is made up of hook 21 and hook base 20, and hook 21 is fixed on wind deflector 3, and hook base 20 is fixed on main frame 1; Described magnetic connecting mechanism 5 is made up of firm banking 10, sucker 11, magnet 14 and iron block 15, magnet 14 to be embedded in firm banking 10 in the heart, firm banking 10 is fixed on main frame 1, iron block 15 to be embedded in sucker 11 in the heart, sucker 11 is fixed on wind deflector 3, and magnet 14 is connected by magnetic with iron block 15; Described firm banking 10 is provided with the first coupling coil 12, first coupling coil 12 is connected with power panel 2, described sucker 11 is provided with the second coupling coil 13, second coupling coil 13 to be connected with keypad 6, the first coupling coil 12 and the second coupling coil 13 are coupled.
The distance of the first described coupling coil 12 and the coupling of the second coupling coil 13 is 0 ~ 10CM, and position relationship is between the two coaxial and parallel to each other, the second coupling coil 13 made and the electromagnetic coupled effect of the first coupling coil 12 stronger.
As shown in accompanying drawing 4,5, demodulator circuit, frequency generating circuit, coil driver is included in described power panel 2, the power panel 2 be positioned on main frame 1 produces high frequency alternating signal by inner frequency generating circuit, coil driver drives the first coupling coil 12 be connected with power panel 2 to do the higher-order of oscillation again, the frequency of high frequency alternating signal is 10KHz ~ 20MHz, and the electromagnetic wave that the first coupling coil 12 does higher-order of oscillation generation is distributed in around the first coupling coil 12.
As shown in accompanying drawing 4,6, button, display screen, single-chip microcomputer, modulation circuit, filter circuit, rectification circuit is included in described keypad 6, second coupling coil 13 produces the induced electromotive force of alternation, after the rectification circuit on the keypad 6 be connected with the second coupling coil 13, filter circuit, supply the power consuming device work such as single-chip microcomputer, display screen, button on keypad 6.During user operation lampblack absorber, keypad 6 obtains control signal according to user operation, then by modulation circuit, the control signal of user is modulated on the second coupling coil 13, then is sent by the second coupling coil 13.The first coupling coil 12 being in closely coupled relation with the second coupling coil 13 receives the control signal that the second coupling coil 13 sends, carry out demodulation by the demodulator circuit on the power panel 2 that is connected with the first coupling coil 12 again and obtain control signal, thus control the component, illumination etc. of lampblack absorber according to control signal.Because the first coupling coil 12 is relative fixing with the second coupling coil 13 position, but indirect connection relation, so can be connected by the dismountable magnetic connecting structure in accompanying drawing 2, make wind deflector detachable, user friendly dismounting and cleaning.
