Then, the essence system of utility model is using the magnetic attracting effect to realize clutch, in the condition of normal use, Motor can drive guid arm to rotate by the way that magnetic patch and magnet ring are attracting, in a special case, can overcome because magnetic force generate compared with Big frictional force makes magnetic patch produce relative rotation with magnet ring, thus the transmitting of blocking part torque.

Wen Zhong, magnetic patch and magnet ring are made by magnetic material, this is magnetic material based can directly or indirectly generate it is magnetic Substance;Magnetic patch can be one piece, be also possible to two or more than two.

The utility model creates the discharging device for automatically controlling guid arm rotation, when manual operation, no longer due to driving member It follows guid arm to rotate, thus, it is possible to prevent all for biggish manual torque to be transferred to motor, thus can avoid motor and biography Abrasion between moving part gear, meanwhile, it also can avoid high-speed rotation occur in motor coil, will not cause to generate larger moment electricity It flows and leads to motor and circuit burnout, it is with the effect for meeting people's manual operation simultaneously.

The utility model automatically controls the discharging device of guid arm rotation, when guid arm is in the position for adding water or reset When, guid arm will not rotate any more, and motor, which continues to rotate, to cause the increase of electric current and motor torque, when motor torque reaches certain When, driving member and guid arm also can produce relative rotation, and it is not in stuck on the one hand making motor, to be conducive to improve motor Service life, on the other hand, guid arm no longer by its torque totally tansitive to motor, makes electric current not continue to increase, motor It continues to rotate and the increase of electric current is no longer caused just not will lead to burning for motor and circuit, thus, it need not can be arranged again in circuit Position switch and its detection circuit, are simplified circuit, reduce manufacturing cost.

In the discharging device of this automatic control rotation, since detection circuit and position switch being no longer arranged in circuit, and can The rotation time of motor is calculated according to the stroke of guid arm, with realizing guid arm plus water or reset, thus production was installed The accurate requirement that position switch assembly can also be exempted in journey then can be further simplified assembly technology, be conducive to further decrease The cost of the manufacturing.

It is preferred that being provided with deceleration mechanism in above scheme, between motor and driving member.In this way, motor can pass through Deceleration mechanism drives driving member, so that the matching of revolving speed is better achieved or reduces the requirement to motor.
