Mistaken touch prevention type intelligent switch based on Internet of Things

[0030] Specific embodiments: when the soot sensor 5 detects that the oil fume content in the air is relatively large, the signal of the soot sensor 5 is transmitted to the Internet of Things control terminal, and the Internet of Things control terminal controls the micro pump body 10 to start, and the output power of the micro pump body 10 Next, pump the saponified emulsion inside the soap tank 9 into the infusion tube 12 inside the protection frame 3, and connect it to the inside of the spray frame 15 through the branch pipe 16. After the micro pump body 10 is controlled by the Internet of Things control terminal, start the micro Air pump 22, under the effect of micro-air pump 22, the compressed air is blown out from airflow pipe 21, and in the spray frame 15, the high-speed airflow blown out by airflow pipe 21 passes through the gas distribution plate 17, and is ejected from the gap, while branch pipe 16 will The saponified emulsion is sprayed from the cone-shaped liquid separation surface 18. When the liquid and gas meet, the air velocity generally reaches 200-340m/s, and the air velocity is much higher than the flow velocity of the saponified emulsion, so there is a relatively large relative velocity between the two fluids. , so as to generate considerable friction, so that the saponified emulsion is atomized, sprayed from the nozzle 19 to the surface of the switch body 1, and the oil molecules on the surface of the switch body 1 are saponified, so as to facilitate the removal of the oil fume on the surface of the switch body 1, and at the same time When a person uses the switch body 1, the protective frame 3 is opened, and the protective frame 3 is pushed to move upwards. Since the rotating rod 7 is rotationally connected with the side wall of the protective frame 3, when the wiper strip 8 contacts the surface of the switch body 1, the protective frame is dragged. When the frame 3 moves, the wiping bar 8 starts to rotate and wipe the surface of the switch body 1, so as to wipe off the saponified soot molecules.

[0031] In this solution, two fixed blocks 24 are connected to the top of the switch body 1, and a spring 25 is connected to the top of the fixed block 24. A magnet 26 is connected, and a plurality of metal sheets 27 are connected to the bottom of the protective frame 3, and the metal sheets 27 and the magnets 26 are adhered to each other. After the user pushes the protective frame 3 and uses the switch body 1, the protective frame 3 is When pulling apart, because one end of the spring 25 is fixedly connected to the inner wall of the protection frame 3, under the action of the protection frame 3, the spring 25 is in a stretched state. 25 returns to the original position under the elastic force, and when the metal sheet 27 and the magnet 26 at the bottom of the protection frame 3 contact each other, the magnet 26 and the metal sheet 27 are mutually adsorbed, and the protection frame 3 has played a position-limiting protection.

[0032] In this solution, one end of the oil fume sensor 5 is provided with a push-pull bump 28, and the push-pull bump 28 is connected to the protection frame 3, and a plurality of anti-slip grooves 29 are arranged on the outside of the push-pull bump 28. Both hands contact push-pull projection 28, because the outside of push-pull projection 28 is provided with a plurality of anti-skid grooves 29, increased the frictional force of personnel's palm and protection frame 3 outsides, avoided personnel's hand-slip phenomenon when pushing protection frame 3.

[0033] In this solution, the outside of the soap tank 9 is provided with an injection nozzle 30. After the saponified emulsion inside the soap tank 9 is used up, the personnel inject the saponified emulsion into the soap tank 9 through the injection nozzle 30.

[0034] In this solution, the fume sensor is preferably TGS2100, the micro solenoid valve is preferably 5523, the micro pump body is preferably PYP032, and the micro air pump is preferably DQB380-FB-3. .
