It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] Reference Figures 1-5The utility model provides an elevator maintenance dust removal device, including second telescopic pipe 2, the top of second telescopic pipe 2 is fixedly connected with dust collecting cover 4, and second telescopic pipe 2 is connected with dust collecting cover 4, the inner surface wall of dust collecting cover 4 is fixedly connected with annular fixed plate 14, the setting of annular fixed plate 14 is convenient for the fixed brush 5 to carry out, and the installation position of brush 5 is limited, the top of annular fixed plate 14 is fixedly connected with brush 5, wherein the outer surface wall of brush 5 is fixedly connected with dust collecting cover 4, and a plurality of dust suction holes 20 are arranged in the inside of brush 5, one side of second telescopic pipe 2 is provided with bearing box 9, the inner chamber bottom of bearing box 9 is fixedly connected with air draught fan 18, wherein the air inlet of air draught fan 18 is fixedly connected with bearing box 9 by bolt, and the air inlet of air draught fan 18 is communicated with the bottom of second telescopic pipe 2 by second air hose 8, specifically, the air inlet of air draught fan 18 will suck the air in the inside of second telescopic pipe 2 through second air hose 8, because dust collecting cover 4 is communicated with second telescopic pipe 2, so the dust and rubbish in the elevator car are sucked into the device through the dust suction hole 20 in the top of brush 5.

[0024] Further, one side of second telescopic pipe 2 is provided with first telescopic pipe 1, and second telescopic pipe 2 and first telescopic pipe 1 are parallel to each other, the inner diameter of second telescopic pipe 2 is greater than the inner diameter of first telescopic pipe 1, to ensure that even if the gas in first telescopic pipe 1 exists to flow out, the pressure in the inside of first telescopic pipe 1 will always be greater than the pressure in the inside of second telescopic pipe 2, so that the lengthening of first telescopic pipe 1 is finally realized, one end of first telescopic pipe 1 is fixedly connected with second telescopic pipe 2 through first fixed sleeve 3, and the other end is fixedly connected with second telescopic pipe 2 through second fixed sleeve 6, the setting of first fixed sleeve 3 ensures that when first telescopic pipe 1 lengthens, second telescopic pipe 2 can lengthen simultaneously with first telescopic pipe 1, one side of bearing box 9 is fixedly connected with dust collecting box 10, the air outlet of air draught fan 18 is communicated between bearing box 9 and dust collecting box 10, dust collecting box 10 is communicated with the bottom of first telescopic pipe 1 through first air hose 7, specifically, air draught fan 18 also releases the gas into dust collecting box 10 through the air outlet while sucking the gas, and the gas flows into the inside of first telescopic pipe 1 through first air hose 7, because the air continuously flows in, the pressure in the inside of first telescopic pipe 1 gradually increases, so that the length of first telescopic pipe 1 becomes longer.

[0025] Further, the inner cavity bottom of the dust cover 4 is provided with a fan blade 13, and the inner wall of the dust cover 4 is fixedly connected with a fixed support 15. The fixed support 15 plays a role of stably fixing the fan blade 13 in the inner cavity of the dust cover 4. The fixed support 15 and the fan blade 13 are rotationally connected through a connecting rod 21. One end of the connecting rod 21 is rotationally connected with the inner wall of the fan blade 13, and the other end is fixedly connected with the top of the fixed support 15. The high-speed rotation of the fan blade 13 can generate strong negative pressure to form suction force to suck dust, improve the generation efficiency of suction force, and control and guide the flow direction of the sucked air flow to flow through the device in the best path. Optimizing air flow guidance helps to improve dust collection effect and dust collection efficiency.

[0026] Further, the top end of the first telescopic pipe 1 is fixedly connected with a circular hole plate 16, and the inner part close to the top end of the first telescopic pipe 1 is provided with an air outlet hole 17. At the same time that the pressure in the first telescopic pipe 1 increases, a small amount of gas flows out through the circular hole plate 16 and the air outlet hole 17, thereby avoiding the occurrence of safety hazards and ensuring that the air blower 18 can continuously suck in gas and continuously perform dust collection work.

[0027] Further, the second air hose 8 and the bearing box 9 are threadedly connected through a second threaded union pipe 12, and the first air hose 7 and the dust collection box 10 are threadedly connected through a first threaded union pipe 11. The first threaded union pipe 11 and the second threaded union pipe 12 are provided to facilitate the installation and disassembly of the first air hose 7 and the second air hose 8.

[0028] Further, the inner wall of the dust collection box 10 is fixedly connected with two filter screen plates 19, and the two filter screen plates 19 are symmetrical to each other. The filter screen plate 19 plays a role of filtering and collecting dust, prevents dust from entering the first air hose 7, and facilitates disassembly and cleaning.

[0029] In conclusion: when in use, the cleaner starts the air blower 18 and holds the bottom end of the first telescopic pipe 1 and the second telescopic pipe 2, and then the brush 5 is in contact with the surface in the elevator car which needs to be cleaned, so that the cleaning of the elevator car can be carried out. When the brush 5 is cleaning the elevator car, the air inlet of the air blower 18 will suck the air in the second telescopic pipe 2 through the second air hose 8, and since the dust collecting cover 4 is in communication with the second telescopic pipe 2, the fan blades 13 in the inner cavity of the dust collecting cover 4 will rotate under the action of the air flow, and then the dust and garbage in the elevator car will be sucked into the device through the dust suction hole 20 at the top of the brush 5, and the dust will enter the inner cavity of the dust collecting box 10 through the air outlet of the air blower 18, and the air blower 18 will release the gas into the dust collecting box 10 through the air outlet while sucking the gas, and the gas will flow into the inside of the first telescopic pipe 1 through the first air hose 7, and since the air continuously flows in, the pressure in the first telescopic pipe 1 gradually increases, so that the length of the first telescopic pipe 1 becomes longer, and the first fixed sleeve 3 fixes the first telescopic pipe 1 and the second telescopic pipe 2 together, so that the second telescopic pipe 2 and the first telescopic pipe 1 are elongated at the same time, thereby facilitating the cleaner to clean the higher position at the top of the elevator car and reducing the burden of the cleaner. At the same time, a small amount of gas flows out through the round hole plate 16 and the air outlet hole 17 as the pressure in the first telescopic pipe 1 increases, so as to avoid the first telescopic pipe 1 from bursting due to excessive pressure in the first telescopic pipe 1, avoid the occurrence of safety hazards, and also ensure that the air blower 18 can continuously suck the gas and the dust collection work can continuously proceed. Since the inner diameter of the first telescopic pipe 1 is smaller than that of the second telescopic pipe 2, even if the gas in the first telescopic pipe 1 flows out, the pressure in the first telescopic pipe 1 will always be greater than that in the second telescopic pipe 2, so that the first telescopic pipe 1 is elongated.
