Abstract

The invention discloses an ultraviolet sterilized dental cylinder, which comprises a closed hollow cylinder head, and an ultraviolet luminous tube and a control circuit are arranged inside the cylinder cover, the ultraviolet luminous tube is connected to the control circuit, and the control circuit controls whether it works or not . There is a toothbrush jack on the outer surface of the cylinder head and the control circuit, and the inner surface of the lower part of the cylinder head has the same number of jacks as the number of ultraviolet light-emitting tubes, so that the light-emitting tubes can sterilize the tooth cylinder and toothbrush through the jack. By pressing the power switch during disinfection, the control circuit starts timing and makes the ultraviolet light-emitting tube in the working state, and controls the ultraviolet light-emitting tube to stop working when the timing ends. The disinfection time can be realized by adjusting the rheostat on the control circuit. If re-sterilization is required, only the trigger switch of the control circuit needs to be pressed. The invention can conveniently disinfect tooth cylinders and toothbrushes.

specific implementation plan

Figure 1 is a schematic diagram of the circuit of the invention, wherein, E is a 5V power supply composed of two button batteries; five LEDs are 2V ultraviolet lamps, the cathode of which is connected to the negative pole of the power supply, and the anode is connected to the output terminal of the 555 timer ;The switch S2 is a double-throw switch connected in parallel with the normally open contact S1 of the relay J, and the relay J is connected in parallel with the freewheeling diode D7. At the same time, the cathode of the freewheeling diode D7 is connected to the output terminal of the 555 timer, and the anode is grounded; The cathode of the diode D7 is connected to the output terminal of the 555 timer, and the anode is grounded. When disinfection is required, press the switch S2, and the 555 timer will start timing after receiving the trigger pulse. After the relay is powered on, S1 will be closed. After that, although the switch S2 has been disconnected, the closure of S1 will make the whole circuit still work normally until the timing ends. When timing, the five ultraviolet lamps D1-D5 start to work to disinfect toothbrushes and tooth jars. At the same time, the light-emitting diode D6 is on to indicate that the disinfection is in progress. After the disinfection is completed, the light-emitting diode is off to indicate that the disinfection is completed. In addition, the timing time can be changed by adjusting the rheostat R4.
