Fig. 4 is refer to, the protection module 150 further includes alarm module 156, the alarm module 156 and the detection
Module 152 connects, and the alarm module 156 is used to detect the voltage of the power output end 140 in the detection module 152
For the voltage needed for the loaded work piece when, send information warning, thus can output voltage for the voltage of load when,
Prompting is issued the user with, so as to which user can cut off voltage in time, protects the safety of load.
As a kind of mode, the alarm module 156 can be a buzzer, and buzzer is a kind of zund-Burguet apparatus of miniaturization
Part can be divided into two major class of piezoelectric type and electromagnetic type by operation principle.Piezo buzzer is made of Athens potsherd, when to
When piezoelectric ceramic piece is subject to audio signal, under the action of inverse piezoelectric effect, potsherd will send out upper machine with the frequency of audio signal
Tool vibrates, so as to make a sound.The inside of electromagnetic buzzer is made of magnet, coil and vibrating diaphragm etc., works as tone currents
When flowing through coil, coil generates magnetic field, and vibrating diaphragm is then attracted and is discharged with the audio signal identical cycle, so as to generate machine
Tool vibrates, and the sound is sent under the action of resonator.In the present embodiment, suitable buzzer can be selected as needed i.e.
Can, the design of the buzzer can be based on FPGA (Field-Programmable Gate Array), i.e. field programmable gate array
Or CPLD (Complex Programmable Logic Device), i.e., Complex Programmable Logic Devices is designed.
Described to further include guard member (not shown) for electric installation 100, which can be sheathed on voltage transformation module
120th, energy supply control module 130, power input 110, power output end 140 etc., the protection are shown in can be rubber or plastics
Insulating bodies are waited, to avoid the voltage transformation module 120, energy supply control module 130, power input 110, power output end
140 grades are encroached on by introduced contaminantses such as dust, sweat stain, steam, and can prevent from leaking electricity when in use.
In addition, in order to better discriminate between out the voltage conversion circuit of output different voltages, the guard member can be according to described
The output voltage setting of power-switching circuit is different colours, such as when the first voltage conversion circuit and second voltage conversion electricity
During the voltage difference of road output, first voltage can be protected the guard member of circuit be arranged to red, by second voltage conversion circuit
Guard member be arranged to yellow or the combination of other colors, so as to user can be distinguished according to color voltage conversion circuit not so and
Output voltage prevents from malfunctioning when using, and the electronic product for preventing operating voltage relatively low receives higher voltage, and circuit is caused to burn
The problem of ruining.
It should be noted that in an embodiment of the present invention, the first voltage conversion circuit, second voltage conversion circuit
And the guard member on other voltage conversion circuits is also provided with corresponding text prompt or pattern identification, is such as set in guard member
Text prompt or pattern identification of output voltage values etc. is put, therefore, user can be according to these text prompts or pattern identification letter
It is single quickly to distinguish different voltage conversion circuits, it prevents from malfunctioning when using.
In conclusion offer of the embodiment of the present invention is a kind of for electric installation 100, it is described to include power input for electric installation 100
End 110, voltage transformation module 120, energy supply control module 130, power output end 140 and protection module 150, pass through power supply control
The size of voltage of the molding block 130 according to needed for loaded work piece generates a control signal, and power conversion module is according to the control
Voltage of the voltage conversion that signal inputs the power input 110 needed for the loaded work piece, to export the voltage
To the power output end 140, thus with the voltage matches needed for loaded work piece, detection module 152 is according to the control signal
Whether the voltage for detecting the power output end 140 is voltage needed for the loaded work piece, and power-off modular 154 is in the power supply
When the voltage of output terminal 140 is not the voltage needed for the loaded work piece, the power output end 140 is cut off to the load
Power supply, so as to load by the voltage that exports of power output end 140 for electric installation 100 for it is too high or too low when, by disconnected
Electric module 154 automatically powers off, so proof load overtension or it is too low when prevent from being burned, substantially increase the peace of load
Quan Xing.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
