Abstract
The invention discloses an automatic power-off device of a charger. The automatic power-off device comprises a charger main control unit, a charging monitoring circuit, an alarm module, a power source and a storage battery, wherein the charging monitoring circuit and the alarm module are connected with the charger main control unit, and the power source is connected with the storage battery through the charger main control unit; the automatic power-off device further comprises a power-off device connected between the charger main control unit and the power source. Compared with the prior art, the automatic power-off device has the advantages that through the power-off device connected between the charger main control unit and the power source, under the circumstance that the storage battery of an electric appliance is fully charged, the charger can not only give a full charging prompt through the alarm module but also enable the charging power source to be switched off automatically through the power-off device, the storage battery of the electric appliance is prevented from continuing to be charged in a fully charged state, overheating damage to or even the phenomena of spontaneous combustion and spontaneous explosion of the storage battery caused by excessive charging are prevented, and charging safety of the charger is improved obviously.
Description
Technical field
The present invention relates to a kind of charger, specifically a kind of automatic power-off device for charger.
Background technology
At present, development along with electronics technology, many conventional compact electric apparatus can both be realized by the mode of charging the supply of power supply, but there is a new potential safety hazard simultaneously, it is existing charger form, can be full of and make prompting electric in the situation that at electrical appliance, but charger is still in work, the charge power supply if user can not be broken in time, the storage battery of electrical appliance is still being recharged under the saturated state that charges, so just be easy to cause storage battery to cross cause thermal damage, even cause spontaneous combustion, self-destruction, this security incident had occurred repeatedly, brought great hidden danger to people's safety of life and property.
Summary of the invention
The problem existing for above-mentioned prior art, the invention provides a kind of automatic power-off device for charger, can be in the situation that the storage battery of electrical appliance be full of electric, charger is not only made and is full of electric prompting, while can be cut off charge power supply automatically, avoids the storage battery of electrical appliance to continue charging under the saturated state that charges, and prevents that storage battery is because too charging cause thermal damage occurred, the phenomenon of even spontaneous combustion, self-destruction, significantly improves the fail safe of charger charging.
To achieve these goals, the charging observation circuit and the alarm module that the present invention includes charger main control unit and be attached thereto, and by the interconnective power supply of charger main control unit and storage battery; Also comprise the breaker device being connected between charger main control unit and power supply.
Described breaker device is electromagnetic relay.
The tripper of described breaker device for being formed by tongue tube and permanent magnets.
Compared with prior art, this automatic power-off device for charger is by the breaker device accessing between charger main control unit and power supply, can be in the situation that the storage battery of electrical appliance be full of electric, charger is not only made and is full of electric prompting by alarm module, can automatically cut off charge power supply by breaker device simultaneously, avoided the storage battery of electrical appliance to continue charging under the saturated state that charges, prevent that storage battery is because too charging cause thermal damage occurred, the phenomenon of even spontaneous combustion, self-destruction, has significantly improved the fail safe of charger charging.
Accompanying drawing explanation
Fig. 1 is theory structure block diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention will be further described.
As shown in Figure 1, this automatic power-off device for charger comprises charger main control unit and the charging observation circuit and the alarm module that are attached thereto, and by the interconnective power supply of charger main control unit and storage battery; Also comprise the breaker device being connected between charger main control unit and power supply.Whether this automatic power-off device for charger is full by charging monitoring circuit monitors level of charge, by the monitor signal of charger main control unit processing controls charging observation circuit, when charging is full, charging observation circuit will be to charger main control unit transmitted signal, charger main control unit now will send enabling signal to alarm module and breaker device, by alarm module, make warning, breaker device, by automatic cut-off power, has guaranteed the fail safe of charging then simultaneously; While again charging, breaker device, by by the control auto-closing of charger main control unit, is connected charging circuit.
Embodiment 1, and described breaker device is electromagnetic relay, and electromagnetic relay is directly accessed to charging circuit, is convenient to realize, and can be good at reaching object of the present invention.
Embodiment 2, and the tripper of described breaker device for consisting of tongue tube and permanent magnets is with low cost, is easy to installation and maintenance; In charged state, by permanent magnets adhesive tongue tube, now charging circuit is in conducting state, charge in batteries; When charging completes, charger main control unit will be separated with tongue tube by permanent magnets by electromagnetic mode, and tongue tube disconnects, and has now cut off charging circuit.Can complete object of the present invention equally.
This automatic power-off device for charger can be in the situation that the storage battery of electrical appliance be full of electric, charger is not only made and is full of electric prompting by alarm module, can automatically cut off charge power supply by breaker device simultaneously, avoided the storage battery of electrical appliance to continue charging under the saturated state that charges, prevent that storage battery is because too charging cause thermal damage occurred, the phenomenon of even spontaneous combustion, self-destruction, has significantly improved the fail safe of charger charging.
