Abstract
The present invention relates to a drive circuit for rotating a resonance type motor, which utilizes a control part, a triac and two diodes to control the motor to repeatedly rotate right and left. The control part detects trigger signals of alternating current power supply, which are sent from zero point to set time. According to the trigger signals which are sent by the control part, the triac is communicated with the alternating current power supply of the positive half period and the negative half period. The first diode and the second diode respectively causes the alternating current power supply of the positive half period and the negative half period passing through the triac to cause a motor which is used for rotating the resonance type motor to rotate in clockwise and anticlockwise ways.
Description
Technical field
The present invention relates to motor circuit, particularly relate to the drive circuit of the motor of cleaner use.
Background technology
In the ordinary course of things, the head of cleaner is provided with the suction inlet of drawing dust, and the suction inlet place of dust out is provided with brush.The function of brush is as follows, the user head of cleaner is close to the ground when mobile, drop on the dust on ground and will be swept to the dust suction inlet by brush, thereby dust will be inhaled into the dust suction inlet.
But, above-mentioned brush is the foreign matters such as dust that the user head of cleaner carried out just realizing clearing up when mobile ground, its cleaning mode still simply carries out the mode of " sweeping ", so, being attached in cleaning has certain limitation aspect the foreign matter on ground, also have limitation on the other hand, when to be exactly the user with the head of cleaner move, also will take very big strength.
So, the head of nearest cleaner can be provided with can be with the rotating resonance type motor of head left rotation and right rotation, rotating resonance type motor passes revolving force to brush, like this, brush just can about repeatedly the rotation, thereby the purpose of foreign matter on the realization cleaning floor certainly, also can realize the purpose of the head of spin-cleaning device easily.
Fig. 1 is the rotating resonance type motor of cleaner head connection and the schematic diagram of rotating parts.Among the figure, 100 expression rotating resonance type motors, 110 expression rotating resonance type motors drive can about the cylindrical shape rotating parts of rotation repeatedly.
Be provided with linkage 120 between rotating resonance type motor 100 and the rotating parts 110, the function of linkage 120 is the left rotation and right rotation power of rotating resonance type motor can be passed to rotating parts 110.
Rotating resonance type motor 100 with above-mentioned formation is when "on" position, motor 100 with about repeatedly the rotation, at this moment, the revolving force of rotating resonance type motor 100 will be delivered to rotating parts 110 by linkage 120, rotating parts 110 will be that the center rotates repeatedly with rotating shaft 113, thereby drive also rotation repeatedly to the left and right of brush, and then realize the purpose of cleaning floor foreign matter.
Fig. 2 a-Fig. 2 c shows the formation and the operating state thereof of general rotating resonance type motor.In the drawings, 200 expression stators, 210 expression rotors.
Have, rotor 210 is provided with rotation adjustment (adjusting) lever 211 again, and the two ends of rotation adjustment (adjusting) lever 211 connect resonant spring 213a, 213b, 213c, 213d, and along with the change of the direction of rotation of rotating adjustment (adjusting) lever 211, resonant spring compresses or extends.
By the above-mentioned rotating resonance type motor that constitutes 100 following effect is arranged, when the 1st group of stator coil 203a, 203c energized, rotor 210 will be as shown in Fig. 2 b, carry out the clockwise direction rotation, like this, along with the rotation of rotor 210, the rotation adjustment (adjusting) lever is rotation together thereupon also.
At this moment, along with the rotation of rotation adjustment (adjusting) lever 211, resonant spring 213a, 213c are compressed.Along with the elongation of resonant spring 213b, 213d, the rotation of the adjustment (adjusting) lever 211 of rotation stops, and like this, rotor will no longer rotate and rest on the position shown in Fig. 2 b.
Then, when the 1st group of stator coil 203a, 203c switched on again, rotor 210 will be rotated counterclockwise shown in Fig. 2 c, and along with the rotation of rotor 210, resonance adjustment (adjusting) lever 211 also is rotated together.
At this moment, along with the rotation of resonance adjustment (adjusting) lever 211, resonant spring 213b, 213d will be compressed.When resonant spring 213a, 213c extended, the adjustment (adjusting) lever 211 of rotation stopped the rotation, and like this, rotor 210 also no longer is rotated, and rotor will rest on the position shown in Fig. 2 c.
That is to say, rotating resonance type motor 100 has following described effect, when last alternately the energized of the 1st group of stator coil 203a, 203c, rotor 210 with about repeatedly the rotation, about rotor 210 repeatedly rotation will pass to linkage 120, pass to rotating parts 110 by linkage 120 again, allow and rotate repeatedly about rotating parts, thereby make rotation repeatedly about brush, and then realize the purpose of cleaning floor foreign matter.
