Abstract
The utility model relates to the technical fields of garbage pulverator, more particularly to the garbage pulverator of work functions is automatically stopped with zero load.The switch that user closes garbage pulverator makes motor start to work, even if user forgets to turn off the switch after, also load detecting module can be automatically waken up after the first preset time of motor operation to detect the load condition of motor, trigger switch disconnects power supply if load detecting module detects that motor is in light condition, prevent in this way user forget close garbage pulverator and no-load running overlong time causes electrical machinery life to shorten, protection equipment can be played, meet power conservation requirement, also convenient for users to use to a certain extent simultaneously, preferably improve security reliability, guarantee the more convenient lasting use of user.
Description
Technical field
The utility model relates to the technical fields of garbage pulverator, more particularly to are automatically stopped work functions with zero load
Garbage pulverator.
Background technique
Current existing Domestic refuse pulverizer has generally all filled overload protective device, and the effect of overload protection usually exists
Work when electric motor short circuit or cutterhead block, effect is to stop protecting motor under emergency rating, however if user makes
Forget to close garbage disposer after, it will always be in working condition, motor working time too long motor hair under light condition
Heat, but overload protection state will not be entered, such empty load of motor duration of runs, the too long electrical machinery life that will lead to shortened.
Utility model content
The purpose of the utility model is to provide the garbage pulverators that work functions are automatically stopped with zero load, can prevent
User forgets to close garbage pulverator and no-load running overlong time causes electrical machinery life to shorten.
The utility model provides the garbage pulverator that work functions are automatically stopped with zero load, including switch, motor, first
Delay circuit and load detecting module for detecting the motor load state, the first delay circuit obtain electric fortune in the motor
The load detecting module is waken up after the first preset time of row, the load detecting module detects that the motor is in unloaded shape
State then triggers the switch and disconnects power supply.
It wherein, further include the second delay circuit, the load detecting module detects that the motor is in light condition then
The switch disconnection power supply is triggered again after triggering the second delay circuit the second preset time of delay.
Wherein, first delay circuit and second delay circuit are same circuit.
Wherein, the load detecting module detects the electric current of the motor.
Wherein, the load detecting module detects the power input to a machine.
Wherein, the load detecting module detects the revolving speed of the motor.
Wherein, the load detecting module detects the output torque of the motor.
The utility model has the following beneficial effects: the switch that user closes garbage pulverator makes motor start to work, that is, use
Family is forgotten to turn off the switch after, and load detecting module can be also automatically waken up after the first preset time of motor operation to detect motor
Load condition, if load detecting module detects that motor is in light condition trigger switch disconnect power supply, prevent from using in this way
Family is forgotten to close garbage pulverator and no-load running overlong time causes electrical machinery life to shorten, and can play protection equipment, meet
Power conservation requirement, at the same it is also convenient for users to use to a certain extent, security reliability is preferably improved, guarantees user more
Convenient lasting use.
Detailed description of the invention
Using attached drawing, the utility model is described in further detail, but the embodiment in attached drawing is not constituted to the utility model
Any restrictions for those of ordinary skill in the art without creative efforts, can also be according to following attached
Figure obtains other attached drawings.
Fig. 1 is the circuit block diagram of the utility model garbage pulverator.
Including: 1 in Fig. 1, --- --- --- the second delay circuit, 4 --- motor, 5 --- load for switch, 3 for power supply, 2
Detection module, 6 --- the first delay circuit.
Specific embodiment
The utility model is further described with the following Examples.
The utility model provides the garbage pulverator that work functions are automatically stopped with zero load, as shown in Figure 1, including power supply
1, switch 2, motor 4, the first delay circuit 6 and the load detecting module 5 for detecting 4 load condition of motor, the first delay electricity
Road 6 wakes up load detecting module 5 after motor 4 obtains the first preset time of electricity operation, if load detecting module 5 detects motor 4
The switch 2 is then triggered in light condition and disconnects power supply, if load detecting module 5 detects that motor 4 is in load condition
The switch 2 is not triggered.
The switch 2 that user closes garbage pulverator makes motor 4 start to work, even if user forgets to turn off the switch 2 after,
Motor 4 can also automatically wake up load detecting module 5 after running the first preset time to detect the load condition of motor 4, if load
Detection module 5, which detects, to be in light condition by motor 4 then trigger switch 2 disconnects power supply, and garbage pulverator stops working, and prevents in this way
Only user forgets to close garbage pulverator and no-load running overlong time leads to 4 lost of life of motor, can play protection equipment,
Meet power conservation requirement, while also convenient for users to use to a certain extent, preferably improve security reliability, guarantees to use
The more convenient lasting use in family.
In the present embodiment, which further includes the second delay circuit 3, and load detecting module 5 detects at motor 4
It is then triggered in light condition and triggers the disconnection of switch 2 power supply after the second delay circuit 3 is delayed the second preset time again, in this way may be used
Also in normal work to avoid garbage pulverator, the mistake of load detecting module 5 survey garbage pulverator, which has crushed, finishes, and passes through second
Delay circuit 3 is delayed after the second preset time, so that it may ensure that garbage pulverator has crushed to finish and just power off.
Wherein, the first delay circuit 6 and the second delay circuit 3 can be same circuit to realize the two delay functions.
In the present embodiment, load detecting module 5 detect detection mode can there are many, as load detecting module 5 detect
The electric current or input power or revolving speed or output torque of motor 4.
Finally it should be noted that above embodiments are only to illustrate the technical solution of the utility model, rather than to this reality
With the limitation of novel protected range, although being explained in detail referring to preferred embodiment to the utility model, this field it is general
Lead to it will be appreciated by the skilled person that can be with the technical solution of the present invention is modified or equivalently replaced, without departing from this
The spirit and scope of utility model technical solution.
