Description

Technical Field

[0001] The invention relates to the technical field of air purification, in particular to an air circulation device for an animal laboratory. Background Art

[0002] When conducting medical experiments, animal laboratories are often needed for scientific experiments. Usually, the excrement of animals in the laboratory will produce waste gas and waste liquid, especially hair loss, which will affect the health of animals and staff in the animal laboratory. In order to solve the above problems, air circulation devices are generally equipped in the laboratory to circulate and purify the air. Existing laboratory air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure light mineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.

[0003] For example, a Chinese patent with application number 202122750674.1 discloses an air circulation device for an animal laboratory, including a box, an accessory box is fixedly installed on the top of the box, a connection box is fixedly installed on the bottom of the inner cavity of the accessory box, and a first vacuum pump is fixedly installed on the left side of the inner cavity of the accessory box. The air inlet end of the first vacuum pump is connected to the connection box, and the top of the connection box is rotatably connected to a hollow tube, and the gas is extracted into the neutralization box through the first vacuum pump. At the same time, the microporous atomizer can oscillate the neutralization liquid in the atomization box into a water mist state, and the water mist is transported to the neutralization box through a fan, so that the irritating gas in the air can fully react with the neutralization liquid, and the reacted gas is filtered again through an activated carbon filter plate and a bamboo charcoal filter plate, and finally discharged to the outside of the box again, thereby achieving the effect of eliminating the irritating gas in the air. Animal laboratory air circulation devices similar to this technology can effectively solve the problem of irritating odors in animal experiments.

[0004] However, animals in animal laboratories generally have the problem of hair falling. The fallen hair easily floats in the air, which not only affects the laboratory environment of the experimenters, but also is filtered and gathered at the filter plate, which can easily cause the filter plate to be blocked for a long time, affecting the filtering effect of the filter plate. If the filter plate is cleaned manually frequently, it will not only increase the workload of the staff, but also affect the normal work of the animal laboratory.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

A tape is wound on the tape roller 24, and the tape is fixedly connected to the recovery roller 25 after passing around the pushing mechanism 23. The pushing mechanism 23 can push down the tape between the release mechanism 21 and the winding mechanism 22 to force the tape roller 24 to rotate, thereby releasing the tape on the tape roller 24, and the pushing mechanism 23 can also push the released tape to flatly adhere to the filter 18 to stick to the hair on the filter 18, and the winding mechanism 22 can drive the recovery roller 25 to rotate to rewind the tape with hair.

[0033] refer to Figure 1 and Figure 2 As shown, the body 10 includes a shell 11, an air inlet 12 is provided at the left end of the shell 11, an air outlet 13 is provided at the right end of the shell 11, and a mounting plate 14, an activated carbon adsorption plate 15, a UV lamp tube 16 and a fan 17 are fixedly installed in the shell 11 from left to right in sequence. A first channel 141 is provided on the mounting plate 14, and a filter 18 is fixedly installed in the first channel 141. The filter 18 can filter the air so that hair in the air cannot pass through the filter 18 in the body 10, but remains on the left side of the filter 18. The activated carbon adsorption plate 15 can purify the air filtered by the filter 18 and adsorb harmful substances in the air. The UV lamp tube 16 can emit ultraviolet rays to disinfect viruses, bacteria and microorganisms in the air. The air outlet end of the fan 17 is connected to the air outlet 13, and the fan 17 can provide power to transport the purified air to the air outlet 13 for discharge, while untreated air is drawn in from the air inlet 12, thereby circulating and purifying the air in the animal laboratory.

[0034] refer to Figures 2 to 8 As shown, the cleaning mechanism 20 includes a release mechanism 21, a reeling mechanism 22, a pushing mechanism 23, a tape roller 24 and a recovery roller 25. The release mechanism 21, the reeling mechanism 22 and the pushing mechanism 23 are all fixedly mounted on the machine body 10. The pushing mechanism 23 is located between the release mechanism 21 and the reeling mechanism 22. The tape roller 24 is wound with tape. The tape roller 24 is rotatably mounted on the release mechanism 21. The recovery roller 25 is mounted on the reeling mechanism 22. The tape on the tape roller 24 passes around the pushing mechanism 24. The bottom end of the mechanism 23 is fixed on the recovery roller 25, and the pushing mechanism 23 can push down the tape between the releasing mechanism 21 and the winding mechanism 22 to force the tape roller 24 to rotate, thereby releasing the tape on the tape roller 24, and then the pushing mechanism 23 can push the released tape to be flat on the filter 18 to stick to the hair on the filter 18, and the winding mechanism 22 can drive the recovery roller 25 to rotate to wind up the tape with hair, thereby cleaning the hair on the filter 18.

[0035] Continue to refer Figure 4 As shown, the release mechanism 21 includes a first support 211 and a first hook seat 214. The first support 211 is provided with a first insertion hole 212, and a first rotating shaft 213 is inserted into the first insertion hole 212. The first rotating shaft 213 is hooked on the first hook seat 214, and the tape roller 24 is rotatably sleeved on the first rotating shaft 213. When the adhesive force of the tape is overcome and the tape is pulled out, the tape roller 24 can rotate on the first rotating shaft 213 to release the tape.

[0036] When the tape on the tape roller 24 is released and a new tape roller 24 needs to be replaced, first remove the first shaft 213 from the first hook seat 214, and then apply force to drag the first shaft 213 to pull the first shaft 213 out of the first socket 212 on the first support 211, that is, the first shaft 213 and the tape roller 24 can be moved away from the machine body 10 by operating the first shaft 213. Applying external force can separate the tape roller 24 from the first shaft 213. Conversely, apply force to put a new tape roller 24 on the first shaft 213, and then insert the first shaft 213 into the first socket 212 on the first support 211, and then control the first shaft 213 to rest on the first hook seat 214, so that the installation of the new tape roller 24 can be completed.

[0037] Continue to refer Figure 3 and Figure 4 As shown, the winding mechanism 22 includes a second support 221, a second hook seat 224 and a rotation driving mechanism 225. The second support 221 is provided with a second plug hole 222, and the second rotating shaft 223 is inserted in the second plug hole 222, and the second rotating shaft 223 can rotate in the second plug hole 222. The second rotating shaft 223 is hooked on the second hook seat 224, and the outer surface of the second rotating shaft 223 has an elastic boss 2231. In this embodiment, the elastic boss 2231 is made of elastic rubber material. The second rotating shaft 223 can abut the recycling roller 25 through the elastic boss 2231 to increase the friction between the second rotating shaft 223 and the recycling roller 25. The rotation driving mechanism 225 is installed on the body 10 and the second rotating shaft 223, and can drive the second rotating shaft 223 to rotate. The rotation of the second rotating shaft 223 can drive the recycling roller 25 to rotate synchronously through the friction between the elastic boss 2231 and the recycling roller 25.

[0038] After the adhesive tape wound on the recycling roller 25 reaches a specified amount, when a new recycling roller 25 needs to be replaced, the adhesive tape between the recycling roller 25 and the tape roller 24 is first cut short, and then the second rotating shaft 223 is removed from the second hook seat 224, and then force is applied to drag the second rotating shaft 223, so that the second rotating shaft 223 can be pulled out of the second insertion hole 222 on the second support 221, and the second rotating shaft 223 and the recycling roller 25 can be operated to move away from the machine body 10, and external force is applied to overcome the abutment force between the elastic boss 2231 and the recycling roller 25, so that the recycling roller 25 can be separated from the second rotating shaft 223. Conversely, force is applied to move the new recycling roller 25 onto the second rotating shaft 223, and the second rotating shaft 223 is inserted into the second insertion hole 222 on the second support 221, and then the second rotating shaft 223 is controlled to be placed on the second hook seat 224, so that the installation of the new recycling roller 25 can be completed, and finally the adhesive tape is fixed on the new recycling roller 25.

[0039] Continue to refer Figure 5As shown, the rotation drive mechanism 225 includes a first reduction motor 2251 fixedly mounted on the body 10 and a transmission hole 2252 opened at one end of the second rotating shaft 223. The output end of the first reduction motor 2251 is fixedly connected to a transmission shaft 2253 plugged into the transmission hole 2252, and the second rotating shaft 223 can transmit torque to the transmission shaft 2253 through the transmission hole 2252 thereon. Exemplarily, the transmission hole 2252 is a regular hexagonal hole, and the transmission shaft 2253 is a regular hexagonal prism matched with the transmission hole 2252. Starting the first reduction motor 2251 can drive the transmission shaft 2253 to rotate, and the rotation of the transmission shaft 2253 can drive the second rotating shaft 223 to rotate synchronously through the transmission cooperation between it and the transmission hole 2252.

[0040] Continue to refer Figure 3 , Figures 6 to 8 As shown, the pushing mechanism 23 includes a third rotating shaft 231, a top roller 232, two guide mechanisms 233 and two driving devices 234. The top roller 232 is rotatably connected to the outer surface of the third rotating shaft 231 through a bearing. The two guide mechanisms 233 are respectively fixedly mounted on both sides of the inner wall of the body 10, and are respectively slidably connected to both ends of the third rotating shaft 231. The two guide mechanisms 233 can guide the movement of the third rotating shaft 231. When the third rotating shaft 231 moves along the guide of the guide mechanism 233, it can complete the movement of downward, rightward, upward and leftward in sequence. The two driving devices 234 are respectively fixedly mounted on both sides of the inner wall of the body 10, and are both slidably connected to the third rotating shaft 231. The driving device 234 can provide power to drive the third rotating shaft 231 to move along the guide of the guide mechanism 233.

[0041] Continue to refer Figure 7 As shown, the guide mechanism 233 includes a guide plate 2331, and a guide groove 2332 is formed on the guide plate 2331. The guide groove 2332 has a downward guide groove 2332a, a rightward inclined groove 2332b, an upward guide groove 2332c and a leftward inclined groove 2332d that are connected from beginning to end. It should be noted that the shape of the rightward inclined groove 2332b is inclined downward from left to right, and the shape of the leftward inclined groove 2332d is inclined upward from right to left. The guide plate 23 A first elastic guide plate 2333 and a second elastic guide plate 2334 are fixedly connected on 31. When the third rotating shaft 231 moves from the right-moving inclined groove 2332b into the upward moving guide groove 2332c, it can press the first elastic guide plate 2333 to deform so as to pass over the first elastic guide plate 2333. When the third rotating shaft 231 moves from the left-moving inclined groove 2332d into the downward moving guide groove 2332a, it can press the second elastic guide plate 2334 to deform so as to pass over the second elastic guide plate 2334.

[0042] The control driving device 234 presses down the third rotating shaft 231, and the third rotating shaft 231 first moves downward along the downward guide groove 2332a (because the second elastic guide plate 2334 blocks the left-moving inclined groove 2332d, the third rotating shaft 231 will not enter the left-moving inclined groove 2332d), and at the same time, the third rotating shaft 231 drives the top roller 232 to move downward synchronously. The downward movement of the top roller 232 can push down the tape between the release mechanism 21 and the winding mechanism 22, so as to force the tape roller 24 to rotate and release the tape, and then Continue to control the driving device 234 to press down the third rotating shaft 231, the third rotating shaft 231 enters the right-moving inclined groove 2332b, and moves along the trajectory of the right-moving inclined groove 2332b to approach the filter 18. Finally, the third rotating shaft 231 overcomes the elastic force of the first elastic guide plate 2333 and passes over the first elastic guide plate 2333, and finally enters the upward guide groove 2332c. At the same time, the third rotating shaft 231 drives the top roller 232 to approach the filter 18, and presses the tape to stick to the filter 18.

[0043] Then the driving device 234 is controlled to push up the third rotating shaft 231, and the third rotating shaft 231 moves up along the upward guide groove 2332c (because the first elastic guide plate 2333 blocks the right-moving inclined groove 2332b, the third rotating shaft 231 will not enter the right-moving inclined groove 2332b), the upward movement of the third rotating shaft 231 drives the top roller 232 to move up synchronously, and the upward movement of the top roller 232 presses the unfolded tape against the filter 18, so that the filter 18 is in full contact with the tape, and then the third rotating shaft 231 enters the left-moving inclined groove 2332d, and the driving device 234 is continued to be controlled to push up the third rotating shaft 231, and the third rotating shaft 231 moves to the left along the trajectory of the left-moving inclined groove 2332d, and finally passes over the second elastic guide plate 2334 and enters the downward guide groove 2332a, returning to the initial state.

[0044] Continue to refer Figure 8 As shown, the driving device 234 includes a guide rail 2341 and a second reduction motor 2342 fixedly connected to the body 10, a slider 2343 is slidably connected to the inner wall of the guide rail 2341, a moving plate 2344 is welded on the slider 2343, a strip hole 2345 is provided on the moving plate 2344, and the third rotating shaft 231 is slidably connected in the strip hole 2345, a screw rod 2346 is fixedly connected to the output end of the second reduction motor 2342, and a screw hole threadedly connected to the screw rod 2346 is provided on the slider 2343. Driving the second reduction motor 2342 can drive the screw rod 2346 to rotate, and the rotation of the screw rod 2346 can drive the slider 2343 to move through the threaded connection between the screw rod 2346 and the slider 2343. The movement of the slider 2343 drives the moving plate 2344 to move, and the movement of the moving plate 2344 through the strip hole 2345 drives the third rotating shaft 231 to move.

[0045] When in use, the fan 17 is started to provide power to transport the sterilized air to the air outlet 13 for discharge, while the untreated air is sucked in from the air inlet 12. The hair in the air cannot pass through the filter 18, but remains on the left side of the filter 18. When the hair on the filter 18 is accumulated too much and needs to be cleaned, the driving device 234 is controlled to press down the third rotating shaft 231, and the third rotating shaft 231 first moves down along the downward guide groove 2332a, and at the same time, the third rotating shaft 231 drives the top roller 232 to move down synchronously, and the downward movement of the top roller 232 can push down the release mechanism 21 and the winding mechanism 22 to force the tape roller 24 to rotate and release the tape, and then continue to control the driving device 234 to press down the third shaft 231, the third shaft 231 enters the right-moving inclined groove 2332b, and moves along the trajectory of the right-moving inclined groove 2332b to approach the filter 18, and finally the third shaft 231 overcomes the elastic force of the first elastic guide plate 2333 and passes over the first elastic guide plate 2333, and finally enters the upward guide groove 2332c, and at the same time the third shaft 231 drives the top roller 232 to approach the filter 18, and presses the tape to stick to the filter 18.

[0046] Then the driving device 234 is controlled to push up the third rotating shaft 231, and the third rotating shaft 231 moves up along the upward guide groove 2332c. The upward movement of the third rotating shaft 231 drives the top roller 232 to move up synchronously. The upward movement of the top roller 232 presses the unfolded tape onto the filter 18, so that the filter 18 is in full contact with the tape, and the hair on the filter 18 is also stuck to the tape. Then the third rotating shaft 231 enters the left-moving inclined groove 2332d, and the driving device 234 is continued to be controlled to push up the third rotating shaft 231. The third rotating shaft 231 moves to the left along the trajectory of the left-moving inclined groove 2332d, and finally passes over the second elastic guide plate 2334 and enters the downward guide groove 2332a, returning to the initial state.

[0047] Finally, the rotation driving mechanism 225 is controlled to drive the second rotating shaft 223 to rotate, and the rotation of the second rotating shaft 223 drives the recovery roller 25 to rotate synchronously, and the recovery roller 25 rotates to reel in the adhesive tape with hair, thereby cleaning the hair on the filter 18.

[0048] Due to the particularity of some laboratories, it is required that the system cannot be stopped once it is running. However, in the above scheme, when cleaning the filter 18, the tape will block the filter 18. During this cleaning process, the air cannot circulate through the filter 18, affecting air purification. Therefore, a second embodiment is proposed to overcome the above problem.

[0049] like Figures 9 to 11 As shown, the second embodiment of the animal laboratory air circulation device of the present invention is shown. The difference between the second embodiment and the first embodiment is that the structure of the mounting plate 14 is different. In addition, in the second embodiment, the animal laboratory air circulation device of the present invention also includes a spare filter 30 and a shielding assembly 40.

[0050] In the second embodiment, a second channel 142 is further provided on the mounting plate 14, and the second channel 142 is located directly below the first channel 141. The spare filter 30 is installed in the second channel 142. The spare filter 30 has the same function as the filter 18 and can filter the air so that hair in the air cannot pass through the spare filter 30.

[0051] The shielding assembly 40 includes a connecting frame 41 fixedly mounted on the movable plate 2344, a winding roller 42 is rotatably connected to the connecting frame 41 through a bearing, and a flexible shielding belt 43 is fixedly connected to the winding roller 42. In the present embodiment, the flexible shielding belt 43 is made of a flexible plastic film, one end of the flexible shielding belt 43 is fixed on the mounting plate 14, and the end is located directly below the spare filter 30, and the flexible shielding belt 43 is flat on one side of the spare filter 30 to block the spare filter 30. An elastic member 44 is fixed between the winding roller 42 and the connecting frame 41, and the elastic member 44 is in a deformed state to maintain elastic force. In the present embodiment, the elastic member 44 is a torsion spring, and the elastic member 44 can provide power to drive the winding roller 42 to rotate, so that the winding roller 42 reels the flexible shielding belt 43.

[0052] When the movable plate 2344 moves downward, the movable plate 2344 moves downward, which will drive the connecting frame 41 to move downward synchronously. The connecting frame 41 moves downward and drives the winding roller 42 to move downward. During the downward movement of the winding roller 42, the elastic member 44 recovers and provides power to drive the winding roller 42 to rotate, so that the winding roller 42 reels the flexible cover belt 43 and opens the spare filter 30 at the same time. That is, when the tape blocks the filter 18, the flexible cover belt 43 opens the spare filter 30, so that the air can continue to circulate through the spare filter 30 to avoid affecting the air purification work. In addition, the unfolded tape part is V-shaped (such as Fig.11 As shown), the left side of the unfolded tape can guide the airflow so that the airflow is guided along the left side of the tape to the spare filter 30. At the same time, impurities in the air can first contact the left side of the tape with the movement of the airflow, stick to the impurities, and reduce the contamination of the spare filter 30 by the impurities.
