Description

TECHNICAL FIELD

[0002] An ultra-low temperature freezing device generally refers to a device capable of operating at extremely low temperatures for freezing, storing or processing substances such as biological samples, food, medical materials, etc.

[0003] In the existing ultra-low temperature freezing device, since the ultra-low temperature freezing device in the factory needs to be continuously operated, frost or ice will appear on the outer surface of the freezer coil used for refrigeration, which will cause the freezer to take a longer time to absorb heat, thereby reducing the refrigeration efficiency of the entire system. Secondly, when the device vibrates, the frost condensed on the outer surface of the coil will fall to the bottom of the device, and long-term accumulation will cause the device interior or the surrounding environment to be humid, increasing the risk of corrosion and electrical failure. At the same time, since the frost accumulated at the bottom of the device increases the weight of the device, it makes the movement and maintenance of the device more difficult, which will affect the efficiency of regular maintenance and emergency repair.

[0004] In addition, since the device is operated in the factory, the content of dust in the air inside the factory is high, so when the device is operated for a long time, the dust in the air will be adsorbed to the heat dissipation port of the device, causing poor ventilation of the heat dissipation port or even blockage of the ventilation port, which will further cause the heat inside the device to be difficult to discharge, thereby causing the temperature inside the device to rise, which will cause the performance of the device to decrease, and even in some cases, the device will be damaged.

[0050] Among them: the driving source 203 is a servo motor, the rotating shaft 202, the rotating shaft 204 and the connecting rod constitute a crank structure, the side of the moving plate 210 is provided with convex points matched with the two groups of vibration plates 105, and the convex points are uniformly distributed on the side of the moving plate 210 and the two groups of vibration plates 105, the limiting swing rod 303 is composed of a vertical rod and a half gear, and a limiting groove is provided in the middle of the vertical rod, the ratchet tooth 308 and the ratchet tooth 309 are mainly used for overturning the rotating rod 306, and the ratchet tooth 307, the ratchet tooth 308 and the ratchet tooth 309 have the same motion properties as the ratchet.

[0051] The effects achieved by the embodiment are as follows: in the prior art, in the existing ultra-low temperature freezing equipment, since the ultra-low temperature freezing equipment in the factory needs to be continuously operated, frost or ice will appear on the outer surface of the freezer coil used for refrigeration, which will cause the freezer to take a longer time to absorb heat, thereby reducing the refrigeration efficiency of the entire system. Secondly, when the equipment vibrates, the frost condensed on the outer surface of the coil will fall to the bottom of the equipment, and long-term accumulation will cause the inside or surrounding environment of the equipment to be humid, increasing the risk of corrosion and electrical failure. At the same time, since the frost accumulated at the bottom of the equipment increases the weight of the equipment, it makes the movement and maintenance of the equipment more difficult, which affects the efficiency of regular maintenance and emergency repair. Compared with the prior art, the cooperation of the rotating shaft one 202 and the rotating shaft two 204 in the vibration deicing mechanism 2 can push the moving plate 210 to realize reciprocating motion, and the vibration plates 105 on both sides of the moving plate 210 can limit the movement of the moving plate 210 during the rising process of the moving plate 210.

Secondly, the rotating shaft two 204 in the vibration deicing mechanism 2 rotates to drive the limiting swing rod 303 to swing, so that the reciprocating rack 305 meshing with the outer teeth of the limiting swing rod 303 moves linearly along the limiting groove opened at the bottom of the freezer shell 101, and the rotating rod two 306 fixed with the reciprocating rack 305 moves reciprocally, pushing the accumulated frost into the collection box 5, thereby achieving the effect of cleaning the frost falling to the bottom of the device, reducing the accumulation time of the frost, and further reducing the risk of corrosion and electrical failure.

[0052] Further embodiments:

[0053] Please refer to Figures 9 to 10 The reciprocating dust removal mechanism 4 includes a driving source two 401 fixedly connected to the side wall of the inner cavity of the freezer shell 101. The driving source two 401 is fixedly connected with a rotating rod three 402 through a driving shaft. The outer surface of the rotating rod three 402 is provided with an annular sliding groove 403. The annular sliding groove 403 is slidably connected with a pulley 404. The pulley 404 is fixedly connected with a reciprocating sleeve rod 405 at the end away from the annular sliding groove 403. The reciprocating sleeve rod 405 is provided with a support block 406 penetratingly sleeved on the outer ring surface. The support block 406 is fixedly connected to the side wall of the freezer shell 101.

[0054] Among them, the diameter of the pulley 404 is the same as the length of the shortest side of the annular sliding groove 403.

[0055] The effects achieved by the embodiment are as follows: in the prior art, since the device is running in the factory, the dust content in the air inside the factory is high, so when the device is running for a long time, the dust in the air will be adsorbed to the heat dissipation port 103 of the device, causing poor ventilation of the heat dissipation port 103 or even blockage of the ventilation port, which will further cause the heat inside the device to be difficult to discharge, thereby causing the temperature inside the device to rise, which will cause the performance of the device to decrease, and even in some cases, the device will be damaged. Compared with the prior art, by rotating the rotating rod three 402 in the reciprocating dust removal mechanism 4, the annular sliding groove 403 opened on the surface of the rotating rod three 402 can be driven to rotate, thereby promoting the pulley 404 to slide inside the annular sliding groove 403. Since the annular sliding groove 403 is a closed sliding groove in the shape of a spiral, the pulley 404 and the reciprocating sleeve rod 405 will move along the guide of the rotating rod three 402 in a reciprocating linear motion while the rotating rod three 402 is rotating, and at the same time, the brush at one end of the reciprocating sleeve rod 405 away from the rotating rod three 402 will clean the heat dissipation port 103, thereby reducing the blockage of dust at the heat dissipation port 103. Further, the heat inside the device can be discharged, prolonging the service life of the device.

[0056] The complete use steps and working principle of the above embodiment are as follows:

[0057] In the initial state: two groups of reciprocating springs two 212 are in a stretched state, the reciprocating spring one 209 is in a compressed state, the top of the limiting outer shell 207 abuts against the top of the protective shell two 211, the moving plate 210 is at the maximum value of its own movement height, the rotating disc 301 is located at the top of the vertical rod opening guide groove of the limiting swing rod 303, the limiting swing rod 303 is in a vertical state with the reciprocating rack 305, the vertical teeth in the ratchet teeth one 307 abut against the ratchet teeth two 308, the rotating rod two 306 does not contact the bottom of the refrigerator shell 101, the driving source two 401 is not started, and the brush on the reciprocating sleeve rod 405 does not contact the heat dissipation port 103.

[0058] The working process of the vibration ice removal mechanism 2 is as follows:

[0059] When the freezer body 1 is in a continuous working state, the driving source one 203 is opened by the manually set program, at this time the driving source one 203 will rotate clockwise, at the same time will drive the rotating shaft one 202 fixedly connected with the output shaft of the driving source one 203 to rotate clockwise, further drive the rotating shaft two 204 fixedly connected with the rotating shaft one 202 to rotate clockwise, since the side of the rotating shaft one 202 and the rotating shaft two 204 is connected through the connecting rod, and the rotating shaft one 202, the rotating shaft two 204 and the connecting rod form a crank structure, so that the connecting rod 205 sleeved on the connecting rod will swing when the output shaft of the driving source one 203 rotates clockwise, when the crank structure rotates one hundred and eighty degrees clockwise, the rotating base 206, the limiting shell 207, the protection shell two 211 and the moving plate 210 will move along the guide of the protection shell two 211 to the direction of the protection shell one 201 through the connecting rod 205, at this time the convex point on the side of the moving plate 210 will contact the convex point on the side of the vibration plate 105, further two groups of vibration plates 105 will appear vibration phenomenon, when the vibration plate 105 vibrates, the refrigeration coil 102 fixedly connected with the side of the vibration plate 105 away from the moving plate 210 will also vibrate, at this time the two groups of reciprocating springs two 212 fixedly connected between the protection shell one 201 and the moving plate 210 will be in a squeezed state, at this time the limiting block 208 fixedly connected at the bottom of the reciprocating spring one 209 will slide upward in the inside of the limiting shell 207, and the diameter of the limiting block 208 is greater than the diameter of the hole through the upper surface of the limiting shell 207, so that the reciprocating spring one 209 will be in a stretched state when the limiting shell 207 moves to the direction of the protection shell one 201, since the moving plate 210 cannot produce violent vibration in the working process, the two groups of reciprocating springs two 212 and the group of reciprocating springs one 209 will produce high frequency and small amplitude vibration effect due to the elastic property of the reciprocating springs one 209 in the process of being pulled down by the connecting rod 205, and the high frequency and small amplitude vibration will be transmitted to the refrigeration coil 102 through the vibration plate 105, at this time the frost attached to the outer surface of the refrigeration coil 102 will be affected by the vibration and fall to the bottom of the freezer shell 101, so that the frost attached to the outer surface of the coil can be vibrated down, further reduce the time of absorbing heat of the freezer, so as to improve the refrigeration efficiency of the whole system;

[0060] When the driving source 203 continues to rotate clockwise, it will drive the rotating shaft 202 and the rotating shaft 204 and the connecting rod to continue to rotate clockwise. When the crank structure composed of the rotating shaft 202 and the rotating shaft 204 continues to rotate clockwise by one hundred and eighty degrees, it will push the rotating base 206, the limiting shell 207 and the reciprocating spring 209 to move to the top of the freezer shell 101 through the connecting rod 205. In the process of moving the limiting shell 207 to the top of the freezer shell 101, the top of the limiting shell 207 will gradually abut against the top of the protective shell 211. At this time, the limiting block 208 slidingly connected in the inner cavity of the limiting shell 207 will gradually fall back to the top of the rotating base 206. When the top of the limiting shell 207 abuts against the top of the protective shell 211, the reciprocating spring 209 will be in a compressed state, and the two groups of reciprocating springs 212 fixedly connected between the protective shell 201 and the moving plate 210 will be in a stretched state. At this time, the vibration ice removing mechanism 2 returns to the initial state, so as to facilitate the continuous use.

[0061] The above working process please refer to Figures 1 to 6 .

[0062] The working process of the reciprocating cleaning mechanism 3 and the reciprocating dust removing mechanism 4 is as follows:

[0063] Further, since the rotating shaft two 204 is known to rotate by the driving of the driving source one 203, when the rotating shaft two 204 rotates clockwise by one hundred and eighty degrees, the rotating disc 301 fixedly connected to the end of the rotating shaft two 204 will rotate clockwise, at this time the sliding rod 302 fixedly connected to the side of the rotating disc 301 away from the rotating shaft two 204 will rotate synchronously, and since the limiting swing rod 303 has a limiting slot in the vertical rod and the sliding rod 302 fixedly connected to the side of the rotating disc 301 is synchronously sliding in the slot of the limiting swing rod 303, the sliding rod 302 will slide in the slot of the limiting swing rod 303 while the rotating disc 301 rotates, and since the sliding rod 302 is arc-shaped, the limiting swing rod 303 will swing through the rotating rod one 304 connected to the side of the support frame 104 at this time, further, the reciprocating rack 305 meshing with the gear teeth of the rotating rod one 304 will move along the horizontal slot at the bottom of the freezer housing 101 to the direction of the heat dissipation port 103, and the ratchet teeth one 307 connected to the side of the reciprocating rack 305 will move to the direction of the heat dissipation port 103, since the rotating rod two 306 is fixedly connected to one side of the reciprocating rack 305, and the two groups of teeth in the ratchet teeth one 307 are "seven" shaped, and the recesses of the two groups of teeth are opposite, when the ratchet teeth one 307 moves to the direction of the heat dissipation port 103 with the reciprocating rack 305, the vertical teeth in the ratchet teeth one 307 will mesh with the ratchet teeth two 308, when the reciprocating rack 305 continues to move to the direction of the heat dissipation port 103, the rotating rod two 306 will rotate clockwise by ninety degrees, at this time the scraper in the rotating rod two 306 will be close to the bottom of the inner cavity of the freezer housing 101, at this time the frost falling on the bottom of the inner cavity of the freezer housing 101 will be scraped by the rotating rod two 306, at this time the rotating rod two 306 and the ratchet teeth one 307 will continue to move to the direction of the freezer housing 101 under the driving of the reciprocating rack 305, when the rotating rod two 306 and the ratchet teeth one 307 move to the ratchet teeth three 309, since the ratchet teeth one 307, the ratchet teeth two 308 and the ratchet teeth three 309 are teeth of the same size, when the teeth in the ratchet teeth one 307 after the flip move to the ratchet teeth three 309, they will not be flipped, at this time the scraper on the rotating rod two 306 will push the frost on the bottom of the inner cavity of the freezer housing 101 to the collecting box 5 through the drainage port 310, at this time the rotating shaft two 204 completes the clockwise rotation by one hundred and eighty degrees, and pushing the frost into the collecting box 5 will clean the frost at the bottom of the device, reduce the accumulation time of the frost, and further reduce the problem of electrical appliance failure caused by moisture;

[0064] When the rotating shaft two 204 continues to rotate clockwise, it will drive the limiting swing rod 303 to swing away from the heat dissipation port 103 around the rotating rod one 304, further driving the reciprocating rack 305 to slide away from the heat dissipation port 103. At this time, the rotating rod two 306 and the ratchet tooth one 307 that push the frost into the collecting box 5 will also move away from the heat dissipation port 103. When the vertical tooth of the ratchet tooth one 307 rotates clockwise by ninety degrees and engages with the ratchet tooth three 309, since the rotating rod two 306 and the ratchet tooth one 307 will continue to move away from the heat dissipation port 103 along with the reciprocating rack 305, at this time the rotating rod two 306 will rotate counterclockwise by ninety degrees due to the blockage of the ratchet tooth three 309, further driving the ratchet tooth one 307 to return to the initial state. At this time, the scraper of the ratchet tooth one 307 will not be in contact with the surface of the cavity of the freezer shell 101, so the frost that falls through vibration will still be in place. When the reciprocating rack 305 moves the rotating rod two 306 and the ratchet tooth one 307 to the area of the ratchet tooth two 308, since the ratchet structure will not reverse, at this time the reciprocating cleaning mechanism 3 completely returns to the initial state. Through the arrangement of the ratchet tooth one 307, the ratchet tooth two 308 and the ratchet tooth three 309, it can avoid pushing the frost away from the area of the collecting box 5, thereby improving the ability of the device to clean the frost;

[0065] When the heat dissipation port 103 accumulates a lot of dust, manually open the driving source two 401, at this time the rotating rod three 402 fixedly connected with the output shaft of the driving source two 401 will rotate. Since the surface of the rotating rod three 402 is provided with an annular slide groove 403, and the annular slide groove 403 is a "spiral" slide groove, and the slide groove is a closed ring, when the driving source two 401 starts, the rotating rod three 402 will rotate, further driving the pulley 404 to move along the track of the slide groove in a reciprocating straight line, at the same time driving the reciprocating sleeve rod 405 fixedly connected with the pulley 404 away from one end of the rotating rod three 402 to move in a reciprocating straight line under the guidance of the supporting block 406. At this time, the brush fixedly connected with the reciprocating sleeve rod 405 away from one end of the rotating rod three 402 will clean the dust accumulated at the heat dissipation port 103, thereby reducing the blockage of dust at the heat dissipation port 103, further enabling the heat inside the equipment to be discharged, prolonging the service life of the equipment.

[0066] The above working process please refer to Figures 7 to 10 .
