Abstract
The utility model relates to a safe and energy-saving mobile phone charger. The safe and energy-saving mobile phone charger comprises a normally-open self-resetting spring switch, a contact of an undercurrent relay, a coil of the undercurrent relay, a circuit board, a power supply input terminal, a power supply output terminal and a charger shell. The normally-open self-resetting spring switch is connected in parallel with the contact of the undercurrent relay and then is connected in series between the power supply input terminal and the circuit board. The coil of the undercurrent relay is connected in series between the circuit board and the power supply output terminal. The normally-open self-resetting spring switch is arranged on the charger shell. The safe and energy-saving mobile phone charger of the utility model has the advantages that after the mobile phone is unplugged from the charger or the mobile phone is fully charged, the contact of the undercurrent relay is disconnected and the charger stops working so that electricity consumption is no longer performed; the energy is saved and usage is safe.
Description
Technical field
The utility model relates to a kind of charger, specifically a kind of charger for mobile phone of energy-saving safe.
Background technology
At present, mobile phone is very universal in people's life, and charger is the requisite annex of mobile phone.After mobile phone was full of electricity, people usually can not in time pull up mobile phone from charger, or just pulled up mobile phone and charger do not pulled up from socket.So, charger is in power supply state always.Not only easily make charger internal electric original paper be subjected to heat ageing, bring potential safety hazard, and the waste electric energy.Have media to report like this: mobile phone charges for a long time, charger does not pull out for a long time---fire hazardous and blast.The committee member Zhou Zhenghong of the Committee of Experts of teenager section of the Chinese Technology Association also says on " energy-saving and emission-reduction famous person classroom is movable ": " if China cellphone subscriber can not in time pull out latch after charging, annual extra power consumption will be over 2,000,000,000 degree.”
Application number is 200820072096.2 Chinese utility model patent, discloses a kind of energy-saving mobile phone charger with automatic circuit break function, and the delay by the time relay realizes auto-breaking.Through the data verification, only have motor time relay can satisfy the delay requirement of charger for mobile phone, need preset the charging interval, but its complicated structure, price is also expensive.Moreover battery of mobile phone is along with the increase that discharges and recharges number of times, and the charging interval can reduce.In life, people generally can just begin charging in mobile phone prompting electric weight deficiency in addition, and the electricity of also having a surplus in mobile phone electric panel this moment.Thus, the required electricity ratio rated value that fills of mobile phone is few, and being full of electric required time will reduce, and because the difference of remaining electricity, the charging required time also can change.In sum, have following drawback: motor time relay complicated structure, price are also expensive; Changing because mobile phone is full of electric required time, if adopt the mode that presets the charging interval, in the time of the charger for mobile phone outage may occurring, mobile phone is underfill electricity or overtime charging also always.
Application number is 201120054830.4 Chinese utility model patent, a kind of energy-saving mobile phone charger is disclosed, by being connected of artificial disconnection charger output and mobile phone, making the outage of Control end, thereby the controlled terminal that is arranged on input line is opened circuit realize energy-conservation.But because the relay in above-mentioned patent is by the mobile phone electric panel power supply, only after mobile phone and charger disconnection, could realize that the relay controlled terminal on input line opens circuit.Therefore the drawback of existence: if when mobile phone is full of electricity, people can't in time pull up mobile phone from charger, and that charger can be in power supply state always.Not only easily make charger internal electric original paper be subjected to heat ageing, bring potential safety hazard, and the waste electric energy.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and a kind of charger for mobile phone of energy-saving safe is provided.As long as mobile phone is full of electricity or mobile phone is pulled up from charger, charger will quit work, thereby has saved electric energy.
The utility model is realized by the following technical solutions.
A kind of charger for mobile phone of energy-saving safe comprises contact, the coil of under current relay, circuit board, power input, power output end, the charger shell of Self-resetting snap switch open in usual, under current relay.Described Self-resetting snap switch open in usual is connected between power input and circuit board with after the contact of under current relay is in parallel.
The coil of described under current relay is connected between circuit board and power output end.
Described Self-resetting snap switch open in usual is arranged on charger shell.
The utility model has following beneficial effect than prior art: mobile phone is pulled up or after mobile phone is full of electricity, open circuit in the contact of under current relay from charger, and charger just quits work, thus no longer power consumption, and energy savings is used safety.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of charger for mobile phone of energy-saving safe comprises contact 4, the coil 6 of under current relay, circuit board 7, power input 1, power output end 5, the charger shell 3 of Self-resetting snap switch 2 open in usual, under current relay.Described Self-resetting snap switch 2 open in usual is connected between power input 1 and circuit board 7 with after the contact 4 of under current relay is in parallel.
The coil 6 of described under current relay is connected between circuit board 7 and power output end 5.
Described Self-resetting snap switch 2 open in usual is arranged on charger shell 3.
Operation principle: during use, light source of charger output 5 inserts mobile phone, and power input 1 inserts socket.Pin Self-resetting snap switch 2 open in usual with hand, the circuit between input 1 and circuit board 7 of switching on power, circuit board 7 begins to cell-phone charging, coil 6 normal operations of under current relay, contact 4 closures of under current relay.Hand is taken away from Self-resetting snap switch 2 open in usual, and charger continues normal operation.Pull up or be full of electricity time from charger when mobile phone, the electric current of the coil 6 of the under current relay of flowing through is less than its operating current, and the contact 4 of under current relay disconnects, thereby charger for mobile phone quits work.
