Furthermore, the lower side surfaces of the deodorization block 26 and the cleaning block 27 are respectively provided with cleaning cotton 55, the lower side surface of the deodorization block 26 is internally provided with a first flow passage 56 which extends upwards and then penetrates through the first flow passage 56 rightwards, the upper side surface of the first flow passage 56 is provided with a second exhaust valve, the first flow passage 56 is internally provided with a second ball valve 57, the right end of the first flow passage 56 is connected with a second expansion pipe 60, the right end of the second expansion pipe 60 is connected with the left side surface of a magnetic suction ring 61, the inner ring surface of the magnetic suction ring 61 is provided with a second check valve, the cleaning block 27 is internally provided with a second through hole 62 which penetrates through the left and right, the right side surface of the processing cavity 25 is internally provided with a third through hole, the lower side surface of the inner cavity 20 is fixedly provided with a butting block 58, the left side surface of the butting block 58 is internally provided with a bearing groove 59, the right side surface of the bearing groove 59 is internally provided with a permanent magnet ring 63, the lower side surface of the deodorization liquid cavity 28 is internally provided with a second flow passage 64 which is communicated with the bearing groove 59, a third check valve is arranged in the second flow passage 64, the magnetic suction ring 61 can pass through the second through hole 62 and the third through hole and is attracted by the permanent magnet ring 63 so as to abut against the right side surface of the receiving groove 59, when the processing block 24 moves leftwards, the second telescopic pipe 60 can be extended, then the deodorant liquid in the deodorant liquid cavity 28 can sequentially pass through the second flow passage 64 and the magnetic suction ring 61 to enter the second telescopic pipe 60, when the processing block 24 moves leftwards for a certain distance, the magnetic suction ring 61 can be separated from the permanent magnet ring 63, and then the deodorant liquid is stored in the second telescopic pipe 60.

The invention relates to a public area air purification and disinfection device, which comprises the following working procedures:

when a user enters and exits the elevator and stands or leaves the pedal 13, the pedal 13 moves downwards or upwards at the moment, so that the fan blades 30 are driven to rotate, air in the elevator can flow widely at the moment, and the air exhaust system of the elevator is matched to finish the air exhaust work.

When a user gets in and out of the elevator to enable the pedal 13 to move up and down, the temporary storage cavity 33 can be gradually filled with disinfectant, the coil spring 47 can gradually accumulate potential energy, air in the temporary storage cavity 33 can be discharged through the exhaust valve 40 in the process that the temporary storage cavity 33 is filled with the disinfectant, the ball valve 34 is automatically opened every certain time, the disinfectant in the temporary storage cavity 33 can flow to the lower side face of the volatilization cavity 12 through the ball valve 34 to volatilize, the fan blades 30 in the process can accelerate volatilization work to disinfect air in the elevator, the ball valve 34 is automatically closed after a certain time, and the work of replenishing the disinfectant is started again.

When the coil spring 47 is full of potential energy and the upper side of the pedal 13 is stained with odor, at this time, a user energizes the electromagnet 50 for a period, the ring block 46 can rotate freely when the electromagnet 50 is energized, and the coil spring 47 releases the potential energy to rotate the ring block 46, the ring block 46 drives the reciprocating screw rod 22 to rotate through the synchronous belt 45 when rotating, the screw rod block 23 drives the processing block 24 to move leftwards, the cleaning cotton 55 in the cleaning block 27 wipes the upper side of the pedal 13 in the process of the leftward movement of the processing block 24, and the deodorizing liquid flows into the second telescopic pipe 60 in the process, when the processing block 24 moves to the left limit, the second ball valve 57 automatically moves rightwards, and the cleaning cotton 55 in the deodorizing block 26 can contact the upper side of the pedal 13, when the second ball valve 57 is opened, the deodorizing disinfectant in the second telescopic pipe 60 flows onto the cleaning cotton 55 in the deodorizing block 26, when the processing block 24 moves to the right limit, the electromagnet 50 is automatically powered off, the second ball valve 57 is closed, the limiting disc 49 rebounds under the action of the fourth spring and enables the limiting ring block 46 to rotate when the electromagnet 50 is powered off, and at the moment, the cleaning work of the upper side surface of the pedal 13 is completed.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
