The hose 24 is located inside the U-shaped member 25, the pressing rod 14 is disposed right below the hose 24, the bottom end of the pressing rod 14 is fixedly connected to the fixing plate 10, and the pressing rod 14 is disposed corresponding to the U-shaped member 25. After the pressure rod 14 moves upward for a certain distance, the pressure rod 14 and the U-shaped part 25 can press the hose 24, and because the hose 24 is pressed, air flow can not pass through the hose 24, so that the air bag 20 is expanded.
The working principle and the using process of the invention are as follows: fig. 1 to 6 are initial states of the device, wherein the lamp bead 7 is located inside the lampshade 3; as shown in fig. 4, the baffle 12 is positioned at the left side of the fan-shaped groove 11, the air bag 20 is not expanded to be lengthened, and the push plate 18 is positioned at the left side of the sliding rod 17;
when the heat generated by the lamp beads 7 in the multiple lamp shades 3 is cooled, the air conditioner 29 is started to generate cold air, the cold air enters the air bags 20 at the side of the first lamp shade 3 through the air inlet pipe 27, continues to enter the interior of the lamp shade 3 through the telescopic air pipe 23, the flexible pipe 24 and the second air pipe 26, and then is discharged into the air bags 20 at the side of the next lamp shade 3 from the interior of the lamp shade 3 through the first air pipe 22, and finally enters the last lamp shade 3 and is discharged to the outside of the shell 1 through the exhaust pipe 28. In the process that cold air passes through the plurality of lamp shades 3, heat generated by the lamp beads 7 is brought to the outside;
when a certain lamp bead 7 breaks down, the starting cylinder 15 drives the fixing plate 10 to move upwards, the fixing plate 10 drives the pressing rod 14 to move upwards, the fixing plate 10 drives the connecting plate 5 to move upwards through the transmission rod 9, and the connecting plate 5 drives the lamp bead 7 and the spare lamp bead 8 to move upwards. As shown in fig. 7, when the pressure rod 14 contacts the bottom of the flexible tube 24, the roller 13 also just rolls and contacts the side surface of the push plate 18, and the lamp bead 7 is separated from the lampshade 3 and has a certain distance. The cylinder 15 is then closed after the pressure bar 14 has moved upwards a distance which allows the pressure bar 14 to press the hose 24. As the hose 24 is pressed, the air flow can not pass through the hose 24, but the air conditioner 29 is continuously filled with air, so that the air bag 20 can be expanded and lengthened, as shown in FIG. 4, the air bag 20 is lengthened to push the push plate 18 to move rightwards, the spring 19 is compressed, the push plate 18 pushes the transmission rod 9 and the connecting plate 5 to move rightwards through the roller 13, when the clockwise rotation angle of the transmission rod 9 exceeds 45 degrees, the connecting plate 5 automatically rotates clockwise under the influence of the gravity center, finally the baffle plate 12 is in contact with the right side of the fan-shaped groove 11, namely the transmission rod 9 rotates clockwise by 90 degrees, and the spare lamp bead 8 is positioned right above the through hole 4. Then starting the air cylinder 15 to drive the fixing plate 10 to move downwards, driving the connecting plate 5 to move downwards by the fixing plate 10 through the transmission rod 9, driving the lamp beads 7 and the spare lamp beads 8 to move downwards by the connecting plate 5, and closing the air cylinder 15 when the spare lamp beads 8 enter the lampshade 3 through the through holes 4;
when the fixed plate 10 drives the pressure rod 14 to move downwards and does not extrude the hose 24 any more, the air flow is not obstructed when passing through the hose 24 any more, at this time, the push plate 18 can move leftwards under the action of the spring 19, so that the air bag 20 is shortened, and finally, the push plate 18 moves to the initial position, so that the air bag 20 is restored to the initial state. It should be noted that, in the process of shortening the air bag 20, the air in the air bag 20 enters the lampshade 3 through the retractable air tube 23, the flexible tube 24 and the second air tube 26, and the air speed of the part is high. At this time, the standby lamp beads 8 do not enter the lampshade 3 yet, and have a certain distance from the through holes 4, namely, the through holes 4 are in an open state. So in this great gas of part speed gets into lamp shade 3, can strike the inside dust of lamp shade 3, make the dust discharge the lamp shade 3 along with the air current through-hole 4 outside, and then play the effect of dust clearance to the inside of lamp shade 3, make light shine the effect better. Meanwhile, the part of gas with higher speed can quickly restore the hose 24 to the initial state when passing through the hose 24;
when lamp pearl 7 and reserve lamp pearl 8 all break down, at this moment need dismantle shell 1, change lamp pearl 7 and reserve lamp pearl 8 to manual 5 anticlockwise rotations 90 degrees with the connecting plate, i.e. debug the initial condition with the device.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
