Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

Referring to fig. 1-2, the present invention provides a technical solution: a UV lighting dual-control lamp applied to a refrigerator comprises a lampshade 1, an LED lamp tube 2 and a UVLED lamp tube 4 are fixedly screwed at the left end of an inner cavity of the lampshade 1, the LED lamp tube 2 is provided with a lighting lamp bead 3, the UV LED lamp tube 4 is provided with a UV LED lamp bead 5, the left side of the lampshade 1 is fixedly connected with a lamp holder 6, the right side of the inner cavity of the lamp holder 6 is fixedly connected with a control device 7, the upper part of the left side of the lamp holder 6 is fixedly connected with an input electrode 8, the lower part of the left side of the lamp holder 6 is provided with an output electrode 9, the input electrode 8 is electrically connected with the output end of a travel switch 10, the input end of the travel switch 10 is electrically connected with the output end of a refrigerator internal power supply 11, the input end of the refrigerator internal power supply 11 is electrically connected with the output electrode 9, and the control device 7 is electrically connected with the illuminating lamp bead 3, the output electrode 9, the input electrode 8 and the UV LED lamp bead 5.

The number of the illuminating lamp beads 3 is five, and the illuminating lamp beads are distributed on the LED lamp tube 2 according to the same distance; the number of the UV LED lamp beads 5 is five, and the UV LED lamp beads are distributed on the UV LED lamp tube 4 at the same distance; the UV LED lamp tube 4 is positioned below the LED lamp tube 2; the refrigerator internal power supply 11 is a 12v dc power supply, and the control device 7 includes two chips, i.e., U11 and U22.

The working principle is as follows: when a UV illumination dual control lamp applied to a refrigerator is used, the device needs to be arranged in the refrigerator and powered on, a circuit diagram of the control device is shown in fig. 2, wherein U11 and U22 are NE555 chips (so-8) (the NE555 chips are the prior art, the utility model discloses do not detail), the input of the internal power supply 11(12Vdc/0Vdc) of the simulated refrigerator is input at the upper left end, the travel switch 10 of the refrigerator door is simulated through an S1 switch, when the S1 switch is bounced, the S1 switch is short-circuited to the upper contact, the illuminating lamp bead 3 is directly lightened by 12V, when the S1 switch is pressed, the S1 switch is short-circuited to the lower contact, the 12V supplies power to U11, and due to the peripheral circuit function of U11, the 3 pin of the U11 chip can delay for about 10S to output a high level, thereby supplying power to U22 and relay S2. Because the upper contact of the relay is a normally closed contact, the UV LED lamp bead 5 is lightened. However, the lighting time is maintained only until the 3-pin output high level of the U22, the 3-pin output high level of the U22 is delayed by about 10s after the UV LED lamp bead is turned on, and when the 3-pin output high level of the U22, the Q11 is operated, and the relay controls the electrical input high level. Relay work adsorbs the shell fragment and causes shell fragment and last contact disconnection, and with lower contact closure, UV LED lamp pearl 5 is cut off the power supply. To sum up, when the switch of S1 bounced, lighting lamp pearl 3 was lighted, and when the switch of S1 pressed, UV LED lamp pearl 5 delayed 10S and opened to keep turning off after 10S. Through the working principle, the functions of starting illumination and time-delay sterilization for 10s when the refrigerator door is closed are realized.
