Description
Technical field
The utility model relates to a kind of field of power supplies, specifically a kind of laptop electric power.
Background technology
Along with the development of society, computer has become the instrument of a lot of people life, work indispensability; And notebook computer is small-sized as one, pocket pc more and more welcomed by the people, but often because most of user is not understand very much to computer system, especially the working condition of computer power is not understood, so cause a lot of power supply to work under the condition of overload, excess temperature for a long time, the instantaneous power device that computer is being opened can produce surge current, this surge current often damages computer, thus has influence on performance and the serviceable life of power supply and even whole computer system.
Utility model content
The purpose of this utility model is to provide a kind of laptop electric power, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of laptop electric power, comprise power supply body, mini-fan, protection network, described mini-fan is fixedly connected with power supply body by insulated bolt, mini-fan is provided with protection network, power supply body interior is provided with negative tempperature coefficient thermistor, relay, rectifier transformer module, temperature data data module, filtering data collection module, negative tempperature coefficient thermistor is electrically connected with input AC with one end after relay parallel connection, the other end is connected with the input end of rectifier transformer module, the output terminal of rectifier transformer module is connected with output current, described temperature data data module, filtering data collection module is collected data and is sent on data processing module and computer CPU, the result that data processing module analyzes data is transferred on display module.
As further program of the utility model: described insulated bolt has four.
Compared with prior art, the beneficial effects of the utility model are: the protection network on the utility model mini-fan can play anti-creeping effect, prevent user from getting an electric shock injured, mini-fan carries out radiating and cooling to power supply, at booting moment, input AC electric current through described negative tempperature coefficient thermistor, power-on surge current absorb by this negative tempperature coefficient thermistor; After exporting normal operating voltage etc. described rectifier transformer module, described normally opened relay is by adhesive, and input AC electric current all flows through the very little relay of impedance.Temperature data data module, filtering data collection module are collected data and are sent to data processing module and computer CPU, the result that data processing module analyzes data is transferred on display module, the thermal overload service condition excessively of reminding user power supply, power work safely, effectively, structure is simple, with low cost, there is very high marketable value, be beneficial to popularization.

In figure: 1, power supply body, 2, mini-fan, 3, protection network, 4, insulated bolt, 5, input AC electricity, 6, negative tempperature coefficient thermistor, 7, relay, 8, rectifier transformer module, 9, temperature data data module, 10, filtering data collection module, 11, output current, 12, data processing module, 13, display module.
Embodiment
Be described in more detail below in conjunction with the technical scheme of embodiment to this patent.
Refer to Fig. 1-2, a kind of laptop electric power, comprise power supply body 1, mini-fan 2, protection network 3, described mini-fan 2 is fixedly connected with power supply body 1 by insulated bolt 4, described insulated bolt 4 has four, mini-fan 2 is provided with protection network 3, protection network 3 can play anti-creeping effect, prevent user from getting an electric shock injured, power supply body 1 inside is provided with negative tempperature coefficient thermistor 6, relay 7, rectifier transformer module 8, temperature data data module 9, filtering data collection module 10, after negative tempperature coefficient thermistor 6 is in parallel with relay 7, one end is connected with input AC electricity 5, the other end is connected with the input end of rectifier transformer module 8, the output terminal of rectifier transformer module 8 is connected with output current 11, described temperature data data module 9, filtering data collection module 10 is collected data and is sent on data processing module 12 i.e. computer CPU, the result that data processing module 12 analyzes data is transferred on display module 13, the thermal overload service condition excessively of reminding user power supply.
Principle of work of the present utility model is: during utility model works, protection network on mini-fan can play anti-creeping effect, prevent user from getting an electric shock injured, mini-fan carries out radiating and cooling to power supply, at booting moment, input AC electric current through described negative tempperature coefficient thermistor, power-on surge current absorb by this negative tempperature coefficient thermistor; After exporting normal operating voltage etc. described rectifier transformer module, described normally opened relay is by adhesive, and input AC electric current all flows through the very little relay of impedance.Temperature data data module, filtering data collection module are collected data and are sent to data processing module and computer CPU, the result that data processing module analyzes data is transferred on display module, the thermal overload service condition excessively of reminding user power supply, ensures the trouble free service of power supply.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned embodiment, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
