[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0026] Example 1

[0027] Reference Figures 1-4 This is the first embodiment of the present utility model, which provides an environmental maintenance device for a library. The environmental maintenance device for a library includes a bookcase 1, and an air exchange mechanism 2 is fixedly installed in the inner cavity of the bookcase 1.

[0028] The ventilation mechanism 2 includes a ventilation component 21, which includes a soundproof cover 211. A soundproof layer 212 is fixedly installed in the inner cavity of the soundproof cover 211, and an air exchanger 213 is fixedly installed on the inner surface of the soundproof cover 211.

[0029] The sound insulation layer 212 is made of porous elastic sound-absorbing material, which can absorb both vibration and sound vibration.

[0030] The ventilation assembly 21 also includes an air intake pipe 214, the left end of which is connected to the right side of the soundproof cover 211, and the rear end of the air intake pipe 214 is connected to an air intake cover 215, on the back of which a filter screen 216 is fixedly installed.

[0031] The ventilation assembly 21 also includes an exhaust pipe 217, the right end of which is connected to the left side of the soundproof cover 211, and the top end of the exhaust pipe 217 passes through the bookcase 1 and extends into the interior of the bookcase 1.

[0032] The ventilation assembly 21 also includes a protective cover 218. The outer surface of the protective cover 218 is fixedly connected to the inner surface of the bookcase 1. Sound insulation cotton 219 is fixedly installed on the inner surface of the protective cover 218. The inner surface of the sound insulation cotton 219 is fixedly connected to the outer surface of the air outlet pipe 217.

[0033] During use, when the humidity and temperature are controlled inside the bookcase 1, the air exchanger 213 will inject outside air into the exhaust pipe 217 through the air inlet pipe 214 and the air inlet cover 215, and spray it out to ventilate and control the temperature inside the bookcase 1. The vibration generated by the air exchanger 213 during use will first pass through the sound insulation layer 212 inside the sound insulation cover 211 for vibration and sound absorption, so that the sound transmitted by the air exchanger 213 during use is small. At the same time, the sound of air flowing in the exhaust pipe 217 will be absorbed by the sound insulation cotton 219 inside the protective cover 218, further improving the quietness of the ventilation equipment inside the bookcase 1 during use.

[0034] Example 2

[0035] Reference Figures 5-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the ventilation mechanism 2 further includes a cleaning component 22. The cleaning component 22 includes a motor 221. The back of the motor 221 is fixedly connected to the front of the filter screen 216. The output end of the motor 221 is fixedly mounted with a rotating shaft 222 through a reducer. The rear end of the rotating shaft 222 passes through the filter screen 216 and extends to the outside of the filter screen 216.

[0036] The cleaning component 22 also includes a transmission gear 223. The inner surface of the transmission gear 223 is fixedly connected to the outer surface of the rotating shaft 222. The outer surface of the transmission gear 223 is connected to a movable belt 225 via a toothed block 224. A rubber push plate 226 is fixedly installed on the outer surface of the movable belt 225.

[0037] The cleaning assembly 22 also includes a cleaning rod 227, the front of which is slidably connected to the back of the filter screen 216, and the inner surface of the cleaning rod 227 is fixedly connected to the rear end of the rotating shaft 222.

[0038] During use, and after prolonged use, a thick layer of dust accumulates on the filter screen 216. The motor 221 drives the rotating shaft 222 to rotate, which in turn drives the cleaning rod 227 to rotate, thus cleaning the dust off the filter screen 216. At the same time, the rotating shaft 222 drives the transmission gear 223 to rotate, which in turn drives the moving belt 225 through the tooth block 224. The moving belt 225 drives the rubber push plate 226 to move, pushing out the dust fibers piled on the cleaning rod 227.

[0039] The remaining structure is the same as that in Example 1.

[0040] Based on embodiments 1-2, the working principle of this utility model is as follows: When the humidity and temperature are controlled inside the bookcase 1, the air exchanger 213 injects external air into the air outlet pipe 217 through the air inlet pipe 214 and the air inlet cover 215, and sprays it out to ventilate and control the temperature inside the bookcase 1. The vibration generated by the air exchanger 213 during use is first absorbed by the sound insulation layer 212 inside the sound insulation cover 211, so that the sound transmitted by the air exchanger 213 during use is small. At the same time, the sound of air flowing in the air outlet pipe 217 is absorbed by the sound insulation cotton 219 inside the protective cover 218. The absorption further improves the quietness of the ventilation equipment in the bookcase 1. At the same time, after long-term use, a thick layer of dust accumulates on the filter screen 216. The motor 221 drives the rotating shaft 222 to rotate, which in turn drives the cleaning rod 227 to rotate, thus cleaning the dust off the filter screen 216. Simultaneously, the rotating shaft 222 drives the transmission gear 223 to rotate, which in turn drives the moving belt 225 through the tooth block 224. The moving belt 225 drives the rubber push plate 226 to move, pushing out the dust fibers piled on the cleaning rod 227.
