Abstract
The utility model relates to a handheld device's safe intelligent charging ware, including the current switchover circuit, be equipped with the input on the current switchover circuit, the input is connected and to be used for the alternating current power supply that charges, output voltage detection circuitry is still connected to the current switchover circuit, output voltage detection circuitry connects and to be used for the output that charges still be equipped with the relay on the circuit between current switchover circuit and the input, the relay passes through control circuit and connects output voltage detection circuitry. The utility model discloses an advantage: whether this charger can detect handheld device and pull out, if detect that handheld device has pulled out or the cell -phone is full of the electricity back, through opening circuit the contact of control circuit control relay, in the outage of input physics, the charger is with regard to the stop work to it is no longer power consumptive, the energy saving, it is safe in utilization, if detect handheld device and insert, through the control circuit control relay.
Description
Technical field
The utility model relates to a kind of seeder, and particularly a kind of a machine three-use seeder for farmland with straw sowed unit and can directly exchange, has integral type and split-type, the utility model agricultural machinery that straw chopping and returning of holding concurrently, fertilising, no-tillage seeding function are integrated.
Background technology
Along with the progress of society, mobile phone is popularized, and is staff one now substantially, and as required or even have several mobile phones, charger is the requisite annex of mobile phone to somebody.After mobile phone is full of electricity, mobile phone usually can not be pulled up from charger by people in time, or just pulls up mobile phone and do not pulled up from socket by charger.So, charger is in power supply state always.Not only easily make the electric original paper of charger internal by heat ageing, bring potential safety hazard, and waste electric energy.Media are had to report like this: mobile phone charges for a long time, charger does not pull out fire hazardous and blast for a long time.After charging, electrical equipment is in and is in holding state for a long time not simultaneously, also can power consumption further, wastes electric energy, does not conform to present advocated environment-friendly type conservation-minded society
Utility model content
The purpose of this utility model is the shortcoming in order to exist in prior art, and the safe and intelligent charger of a kind of handheld device proposed.
To achieve these goals, the utility model have employed following technical scheme:
A kind of safe and intelligent charger of handheld device, comprise current converter circuit, described current converter circuit is provided with input, described input connects the AC power for charging, described current converter circuit also connects output voltage detecting circuit, described output voltage detecting circuit connects the output for charging, and the circuit between described current converter circuit and input is also provided with relay, and relay connects described output voltage detecting circuit by control circuit.
Preferably, described input is alternating current input port.
Preferably, described output is DC output end mouth.
Preferably, described control circuit is testing circuit, it is for detecting the magnitude of voltage exported in described output voltage detecting circuit, after battery charging, after described control circuit detects that the output voltage in output voltage detecting circuit has significantly change, described control circuit controls described relay and disconnects, and stops charge power supply continuing power supply to described current converter circuit.
Preferably, also energy-storage units is provided with in described control circuit, after battery is full of electricity, described control circuit detects that the output voltage in output voltage detecting circuit changes, between the described relay of control disconnects, in described energy-storage units, storing electricity, when next time is when charging, in described energy-storage units, saying that the electricity of storage is for charging.
The utility model has the advantage of: whether the safe and intelligent charger of a kind of handheld device provided by the utility model can detect handheld device and pull out, after detecting that battery has pulled out or is full of electricity, by the contact open of control circuit control relay, in the power-off of input physics, charger just quits work, thus no longer power consumption, energy savings, use safety, as detected, handheld device is inserted, by control circuit control relay.
Accompanying drawing explanation
Fig. 1 is theory diagram of the present utility model.
Embodiment
In order to make the utility model clearly understand, describe in detail this device below in conjunction with accompanying drawing, specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
