[0023] The present utility model will now be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, only showing the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0024] Figure 1 is a schematic structural diagram of the present utility model; Figure 2 is a schematic structural diagram inside the housing of the present utility model; Figure 3 is a schematic diagram of wire connection of the present utility model.

[0025] Combined with the attached Figure 1 and the attached Figure 2 and the attached Figure 3 As shown, there are a housing 1, an AC - DC adjustable voltage power supply board 2, a temperature and voltage acquisition module 4, a sound and light control switch module 6, a self - locking switch 7, an AC input wire 8, and a DC output wire 9. The AC - DC adjustable voltage power supply board 2, the temperature and voltage acquisition module 4, and the sound and light control switch module 6 are installed on the housing 1. The temperature and voltage acquisition module 4, the sound and light control switch module 6, and the AC input wire 8 are all electrically connected to the AC - DC adjustable voltage power supply board 2. A rotary potentiometer 13 is installed on the AC - DC adjustable voltage power supply board 2. The DC output wire 9 is electrically connected to the outlet end of the sound and light control switch module 6. The self - locking switch 7 is installed on the housing 1, and the self - locking switch 7 is electrically connected to the sound and light control switch module 6.

[0026] In the attached Figure 3 L represents the live wire, N represents the neutral wire, + represents the positive electrode, - represents the negative electrode, In represents the incoming line, out represents the outgoing line, S1 represents the sound - controlled switch, S2 represents the light - sensitive switch, S3 represents the remote - control switch, and S4 represents the manual switch.

[0027] A power plug 10 is connected to the end of the AC input wire 8.

[0028] An electrical connector 11 is connected to the end of the DC output wire 9.

[0029] A display screen 12 is fixed on the housing 1, and the display screen 12 is electrically connected to the temperature and voltage acquisition module 4. The display screen 12 can display the voltage, real - time time, and ambient temperature information of this power adapter.

[0030] A USB power supply female socket 5 is installed on the housing 1, and the USB power supply female socket 5 is electrically connected to the AC - DC adjustable voltage power supply board 2

[0031] The socket of the USB power supply female socket 5 is located at the opening of the housing 1. The socket of the USB power supply female socket 5 can be used to externally connect electrical appliances through a USB male head.

[0032] An indicator light 15 is installed on the housing 1, and the indicator light 15 is electrically connected to the AC-DC adjustable voltage power supply board 2. As the rotary potentiometer 13 is turned on (i.e., the knob of the rotary potentiometer 13 is turned from the OFF position to the Min position), the AC-DC adjustable voltage power supply board 2 outputs the minimum DC voltage, and the indicator light 15 lights up. When the rotary potentiometer 13 is turned counterclockwise to the off position (i.e., the rotary potentiometer knob points to the off position), there is no DC power output, and the indicator light 15 goes out.

[0033] The temperature probe of the temperature and voltage acquisition module 4 is located outside the housing 1. The photoresistor of the sound and light control switch module 6 is located outside the housing 1.

[0034] The housing 1 is provided with heat dissipation through holes. A DC wireless remote control switch module 3 for controlling the on-off of the circuit is installed on the housing 1. The DC wireless remote control switch module 3 is paired with the remote control 14 and is electrically connected to the DC power output line 9. The positive circuit of the DC wireless remote control switch module 3 is a non-control circuit and is not responsible for on-off, and the negative circuit is a control circuit and is responsible for on-off.

[0035] The power plug 10 is inserted into a socket (220V AC), and the knob of the rotary potentiometer 13 is turned to change the rotary potentiometer 13 from the (OFF) closed state to the (Min) on state. (OFF means closed, that is, the present invention does not output DC voltage; Min is the minimum DC voltage value output by the present invention; Max is the maximum DC voltage value output by the present invention). The indicator light 15 lights up. The alternating current is converted into direct current by the AC-DC adjustable voltage power supply board 2 and supplies power to the temperature and voltage acquisition module 4 and the USB power supply female socket 5. When the self-locking switch 7 is closed, it also supplies power to the electrical connector 11 at the same time. The real-time time, the site temperature, and the DC output voltage value can be displayed on the display screen 12. The USB power supply female socket 5 can be externally connected to a silent fan, and the electrical connector 11 can be externally connected to an illustrated light box. The start-up operating voltage of the silent fan and the illustrated light box is greater than the Min voltage value. Continue to turn the rotary potentiometer 13 clockwise to increase the voltage, and the silent fan starts up, and the illustrated light box starts up. Continue to turn the rotary potentiometer 13 clockwise to Max, then the fan speed reaches the highest and the light box brightness reaches the brightest. During the process of turning the rotary potentiometer 13, the DC output voltage value can be seen on the 12. When the self-locking switch 7 is pressed, the self-locking switch 7 changes from closed to open. At this time, the present invention changes from the manual mode to the sound control mode (the electrical connector 11 and the connected light box are affected by the mode, and the power supply female socket 5 and the connected fan are not affected by the mode change). When the site illumination is insufficient (such as at night), the user can trigger the sound and light control switch module by making a sound, and the light box starts up and lights up. After a certain period of time, the light box automatically goes out. If it is felt that it is too bright and dazzling at night, turn the rotary potentiometer 13 counterclockwise to reduce the light box brightness to an appropriate level, so that there will be an appropriate brightness when starting up. In the sound control mode, after a certain period of time, the illustrated light box automatically goes out. If you want to keep the illustrated light box lit, just press the self-locking switch 7 to switch from the sound control mode to the manual mode, and the illustrated light box will light up and remain lit. Under normal conditions, when the self-locking switch is in the open state, the illustrated light box can be remotely controlled to be lit and extinguished by the remote control 14.

[0036] When it is necessary to turn off the illustrated light box, turn the rotary potentiometer 13 counterclockwise until the DC output voltage value is lower than the start-up operating voltage value required by the illustrated light box, and the 12 continues to be powered on to display information.

[0037] The working mode of this application is as follows: Insert the power plug 10 into a socket (220V AC), connect the electrical appliance connector 11 to the illustration light box, turn the rotary potentiometer to an appropriate voltage. When the brightness received by the photoresistor (mounted on the chassis 1) on the sound and light control module 6 reaches below the set value, and at the same time the sound wave received by the microphone on the sound and light control module 6 through the heat dissipation holes on the chassis 1 exceeds the set value, the sound control switch closes the control circuit, the sound and light control switch module will turn on, the illustration light box will light up, and the sound and light control switch module will automatically turn off after a certain period of time, and the illustration light box will go out. The illustration light box can also be controlled to turn on and off using the remote control 14.

[0038] Enlightened by the above ideal embodiments of the present invention, through the above description, relevant staff can completely make various changes and modifications within the scope not deviating from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
