Compared with the prior art, the intelligent control device for ultraviolet disinfection lamp of the present utility model has the following outstanding beneficial effects:

(1) The use of single-chip microcomputer to realize intelligent control not only saves energy, but also completely frees operators from ultraviolet radiation.

(2) The structure is simple and easy to use.

Through the setting of the internal program of the single chip microcomputer, the following functions can be realized:

1. Artificial delay work: according to the needs, the operator sets a certain time delay to provide enough time for the evacuation or protection of indoor personnel;

2. Automatic time delay: When the time is artificially delayed or the operator chooses to work directly, the control device can send out sound and light prompts or voice prompts to remind the staff to pay attention to the UV lamp is about to work. At this time, the staff can leave the room or stop disinfection as needed The lamp works or continues to set the delay, otherwise the control device will turn on the ultraviolet disinfection lamp after the automatic delay time expires;

3. Timing off: When the ultraviolet disinfection lamp works for the set time (such as 30-40 minutes), it will automatically turn off the flow disinfection lamp, and at the same time sound and light or voice prompts.

4. Manual shutdown function: During the artificial delay process or the disinfection process, the disinfection lamp can be artificially turned off.

Detailed ways

The intelligent control device for ultraviolet disinfection lamp of the present utility model is described in detail below with reference to the accompanying drawings.

As shown in accompanying drawing 1, the intelligent control device of the ultraviolet disinfection lamp of the present invention is composed of a power conversion assembly A, a single-chip microcomputer U, a relay JK1, a relay JK2, a relay drive circuit E, F, a display device B, a button C and a voice integrated block D composition.

The power conversion component A is connected in series with the relay JK1 and connected in parallel with the power input end of the device to provide power for other components in the control device. The power conversion component A may adopt a transformer rectification method or a switching power supply method.

The relay JK1 is connected with the single-chip microcomputer U through the relay driving circuit E, and a button K is connected with both ends of the relay JK1. The relay JK2 is connected in series between the relay JK1 and the output terminal of the power supply, and is connected with the single-chip microcomputer U through the relay driving circuit F. Relays JK1 and JK2 can be general relays. If solid state relays with TTL input are selected, the relay drive circuits E and F can be omitted. In addition, silicon controlled rectifiers can be used instead of relays. Button K can be selected from various forms of manual buttons.

The display device B, the key C and the voice integrated block D are directly connected with the single-chip microcomputer U. in,

Common display devices such as LED, digital module or liquid crystal module can be used for display device B;

Button C can be input with 1 or more digits. When 1 bit is used, the operator’s intention can be judged according to its closing time, for example: short (within 1 second) represents artificial delay, and each click increases a certain time; medium (1 second to 3 seconds) represents direct connection to the circuit; If it is pressed for a long time (such as more than 3 seconds), it means that the circuit is disconnected and the disinfection lamp is required to stop working. If multi-bit input is used, each key position can be set as required.

Voice integrated block D can choose various types of voice integrated blocks.

As shown in accompanying drawing 2, the operating process and principle of the ultraviolet disinfection lamp intelligent control device of the present utility model are as follows:

First press the button K, and the momentary control relay JK1 is closed when the single-chip microcomputer U is powered on, so that the entire control device is in a charged state. The operator uses the button C to input the command, and the single-chip microcomputer U detects the content of the command. If the command does not require a delay, it will directly enter the automatic delay program and issue audible and visual prompts; if a delay is required, it will enter the delay program first, and then enter the automatic delay program. After the sound and light prompts for a certain period of time, the relay JK2 is closed, and the single-chip microcomputer U starts timing. When the disinfection lamp works for the set time, the relay JK2 is disconnected, the disinfection lamp stops working, and an audible and visual prompt will be issued when it stops within a certain period of time. Finally, the relay JK1 is disconnected, the control device is powered off, and the control process ends normally. In addition, when the controller is in the command input stage, delay stage or work timing stage, the operator can input the stop command, and when the single-chip microcomputer U detects the stop command, it will directly enter the program of disconnecting the relay JK2.

In public places such as schools, kindergartens, and outpatient clinics, artificial delays can be used. After the staff leave work, the control device will turn on the disinfection lamp at a specified time for disinfection. After the disinfection is completed, the control device will automatically turn off the disinfection lamp, saving energy and easy to use. It is also possible to realize the automatic opening and closing of the control device at the specified time every day by writing a program.

The processing and manufacturing of the intelligent control device for ultraviolet disinfection lamp of the present utility model is very simple and convenient, and it can be processed and manufactured according to the general processing method shown in the accompanying drawings.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
