Description

Technical Field

[0001] This utility model relates to the technical field of roof air supply structure for laboratories, specifically a roof air supply structure for a constant temperature and humidity laboratory. Background Technology

[0002] A laboratory is a place where experiments are conducted. Laboratories are the cradle of science, the base of scientific research, and the source of technological development, playing a vital role in technological advancement. Laboratories require a constant temperature and humidity environment, necessitating constant temperature and humidity air conditioning to regulate the air temperature and humidity within the laboratory. This requires the use of roof-mounted air supply structures to deliver air into the laboratory.

[0003] Existing roof-mounted air supply structures for constant temperature and humidity laboratories, while capable of supplying air to the laboratory to regulate temperature and humidity, have limitations. The air outlets are all located at the top, and in summer, cool air sinks while in winter, warm air rises. This results in the existing roof-mounted air supply structure having an outlet temperature higher than the indoor temperature in winter, causing warm air to accumulate at the top of the laboratory. This prevents the warm air from quickly mixing with the indoor air, creating a temperature difference between the upper and lower parts of the room, leading to poor temperature and humidity control and making the system inconvenient to use. Therefore, we propose a new roof-mounted air supply structure for constant temperature and humidity laboratories to address these problems. Utility Model Content

[0004] The purpose of this invention is to provide a roof air supply structure for a constant temperature and humidity laboratory to solve the problems currently existing in the market as mentioned in the background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a roof-mounted air supply structure for a constant temperature and humidity laboratory, comprising a laboratory, wherein a first annular pipe and a second annular pipe are respectively installed on the upper and lower inner walls of the laboratory, and air outlets are equidistantly opened on the inner sides of both the first annular pipe and the second annular pipe, wherein...

[0006] A duct groove is provided on the top of one side of the second annular tube, and a duct groove is also provided through the first annular tube at the position corresponding to the duct groove. A duct runs through the duct groove, and the top of the duct runs through the interior of the laboratory and extends to the roof.

[0007] The air duct is provided with an inner tube. The air duct has a first ventilation groove on its side inside the first annular tube and the second annular tube. The inner tube has a second ventilation groove at the position corresponding to the first ventilation groove. The inner tube is driven to rotate by a drive mechanism.

[0008] Preferably, the bottom end of the duct is closed, and the outer diameter of the duct matches the inner diameter of the duct groove.

[0009] Preferably, the top end of the inner tube is open, and the bottom end of the inner tube is closed.

[0010] Preferably, the first ventilation slots arranged on the upper and lower parts of the air duct are distributed in opposite directions, and the second ventilation slots are located on the same side of the inner duct.

[0011] Preferably, the inner wall of the duct groove is provided with a first sealing ring, the outer side of the inner tube corresponding to the second ventilation groove is provided with a second sealing ring, and the outer sides of the inner tube near the upper ends are provided with a third sealing ring.

[0012] Preferably, the driving mechanism includes a housing, with the housing disposed between the first annular tube and the second annular tube corresponding to the air duct. The housing is connected to the inner wall of the laboratory and communicates with the air duct. The inner tube penetrates the interior of the housing. Limiting plates are symmetrically installed on the upper and lower sides of the inner tube inside the housing. A worm gear is fixedly connected to the outer side of the middle part of the inner tube inside the housing. A worm is rotatably connected to the inner side of the housing corresponding to the worm gear. A motor is installed on the outer side of the housing corresponding to the worm. The shaft end of the motor is fixedly connected to the worm.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In summer, when the temperature inside the laboratory is higher than the supply air temperature, the inner tube is rotated by a drive mechanism. This rotation aligns the second ventilation slot above the inner tube with the first ventilation slot, while the second ventilation slot below the inner tube is misaligned. This allows cold air to enter the first annular pipe through the duct and inner tube when the roof-mounted constant temperature and humidity air conditioner supplies air, and then exits through the air outlet. In winter, when the temperature inside the laboratory is lower than the supply air temperature, the second ventilation slot below the inner tube is aligned with the second ventilation slot, allowing warm air to enter the second annular pipe and then exit through the air outlet. This air supply structure allows air to be supplied from above or below the laboratory depending on the season, causing cold air to sink or warm air to rise, enabling rapid mixing with the laboratory air and effectively improving the constant temperature and humidity effect inside the laboratory.

[0015] This invention uses a first sealing ring to seal the inner wall of the duct groove with the duct, a second sealing ring to seal the inner tube at the second ventilation groove with the inner wall of the duct, and a third sealing ring to seal the upper and lower ends of the inner tube with the inner wall of the duct. Through this sealing structure, the airtightness of the air supply structure is effectively improved, and air leakage is prevented.

[0016] In this invention, when the inner tube needs to be rotated, the controller controls the motor to work, which drives the worm to rotate. The worm then drives the worm wheel to rotate, which in turn drives the inner tube to rotate. The drive mechanism controls the rotation of the inner tube. At the same time, the unidirectional transmission structure formed by the worm and the worm wheel enables the rotation structure of the inner tube to achieve a self-locking function, preventing the inner tube from rotating automatically.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a roof-mounted air supply structure for a constant temperature and humidity laboratory, comprising a laboratory 1, wherein a first annular pipe 2 and a second annular pipe 3 are respectively installed on the upper and lower inner walls of the laboratory 1, and air outlets 4 are equidistantly opened on the inner sides of the first annular pipe 2 and the second annular pipe 3, wherein...

[0024] The second annular pipe 3 has a duct groove 5 on one side top, and the first annular pipe 2 also has a duct groove 5 through it at the position corresponding to the duct groove 5. A duct 6 passes through the duct groove 5, and the top of the duct 6 passes through the interior of the laboratory 1 and extends to the roof.

[0025] The air duct 6 has an inner tube 7 inside. The air duct 6 has a first ventilation groove 8 on its side inside the first annular tube 2 and the second annular tube 3. The inner tube 7 has a second ventilation groove 9 at the position corresponding to the first ventilation groove 8. The inner tube 7 is driven to rotate by a drive mechanism.

[0026] In summer, when the temperature inside laboratory 1 is higher than the supply air temperature, the drive mechanism rotates the inner tube 7. This rotation aligns the second ventilation slot 9 above the inner tube 7 with the first ventilation slot 8, while the second ventilation slot 9 below the inner tube 7 is misaligned with the first ventilation slot 8. This allows the roof-mounted constant temperature and humidity air conditioner to supply air, which then enters the first annular pipe 2 through the air duct 6 and the inner tube 7, and is then ejected through the air outlet 4. In winter, when the temperature inside laboratory 1 is lower than the supply air temperature, the second ventilation slot 9 below the inner tube 7 aligns with the first ventilation slot 8, allowing warm air to enter the second annular pipe 3, and then be ejected through the air outlet 4. This air supply structure allows air to be supplied above or below laboratory 1 according to the season, causing cold air to sink or warm air to rise, enabling rapid mixing with the air inside laboratory 1 and effectively improving the constant temperature and humidity effect inside laboratory 1.

[0027] Please see Figures 1 to 4 The bottom end of the air duct 6 is closed, and the outer diameter of the air duct 6 matches the inner diameter of the air duct groove 5. The top end of the inner tube 7 is open, and the bottom end of the inner tube 7 is closed. The first ventilation grooves 8 arranged on the upper and lower parts of the air duct 6 are distributed in opposite directions, and the second ventilation groove 9 is located on the same side of the inner tube 7.

[0028] Please see Figures 1 to 4 The inner wall of the duct groove 5 is provided with a first sealing ring 10, the outer side of the inner tube 7 corresponding to the second ventilation groove 9 is provided with a second sealing ring 11, and the outer side of the inner tube 7 near the upper two ends is provided with a third sealing ring 12. The first sealing ring 10 seals the inner wall of the duct groove 5 with the duct 6, the second sealing ring 11 seals the inner tube 7 at the second ventilation groove 9 with the inner wall of the duct 6, and the third sealing ring 12 seals the upper and lower ends of the inner tube 7 with the inner wall of the duct 6. The sealing structure effectively improves the airtightness of the air supply structure and avoids air leakage.

[0029] Please see Figures 1 to 4The driving mechanism includes a housing 13. The housing 13 is positioned between the first annular pipe 2 and the second annular pipe 3, corresponding to the air duct 6. The housing 13 is connected to the inner wall of the laboratory 1 and communicates with the air duct 6. The inner pipe 7 penetrates the interior of the housing 13. Limiting plates 14 are symmetrically installed on the upper and lower sides of the inner pipe 7 within the housing 13. A worm gear 15 is fixedly connected to the outer side of the middle portion of the inner pipe 7 within the housing 13. A worm 16 is rotatably connected to the inner side of the housing 13 corresponding to the inner side of the worm gear 15. A motor 17 is installed on the outer side of the housing 13 corresponding to the outer side of the worm 16. The shaft end of the motor 17 is connected to... The worm gear 16 is fixedly connected. When it is necessary to drive the inner tube 7 to rotate, the controller controls the motor 17 to work (the control principle and model of the electrical appliance are irrelevant to the problem to be solved in this solution, so the existing technology is directly quoted without detailed explanation of its principle and model). The motor 17 drives the worm gear 16 to rotate, and the worm gear 16 drives the worm wheel 15 to rotate through meshing. The worm wheel 15 drives the inner tube 7 to rotate. The drive mechanism is set to control the rotation of the inner tube 7. At the same time, the unidirectional transmission structure formed by the worm gear 16 and the worm wheel 15 enables the rotation structure of the inner tube 7 to achieve a self-locking function, preventing the inner tube 7 from rotating automatically.

[0030] Working principle: This roof-mounted air supply structure for a constant temperature and humidity laboratory operates as follows: In summer, when the temperature inside laboratory 1 is higher than the supply air temperature, the inner tube 7 is rotated by a drive mechanism. This rotation aligns the second ventilation slot 9 above the inner tube 7 with the first ventilation slot 8, while the second ventilation slot 9 below the inner tube 7 is misaligned with the first ventilation slot 8. This allows cold air to enter the first annular pipe 2 through the air duct 6 and the inner tube 7, and then be ejected through the air outlet 4. In winter, when the temperature inside laboratory 1 is lower than the supply air temperature, the second ventilation slot 9 below the inner tube 7 is aligned with the first ventilation slot 8, allowing warm air to enter the second annular pipe 3, and then be ejected through the air outlet 4. This air supply structure allows air to be supplied above or below laboratory 1 according to the season, causing cold air to sink or warm air to rise, quickly mixing with the air inside laboratory 1 and effectively improving the constant temperature and humidity effect inside laboratory 1.

[0031] The first sealing ring 10 seals the inner wall of the duct groove 5 to the duct 6, the second sealing ring 11 seals the inner tube 7 at the second ventilation groove 9 to the inner wall of the duct 6, and the third sealing ring 12 seals the upper and lower ends of the inner tube 7 to the inner wall of the duct 6. This sealing structure effectively improves the airtightness of the air supply structure, preventing air leakage. When the inner tube 7 needs to rotate, the controller controls the motor 17 (the control principle and model of the electrical appliance are irrelevant to the problem this solution aims to solve, so existing technology is directly cited without detailed explanation of its principle and model). The motor 17 drives the worm gear 16 to rotate, which in turn drives the worm wheel 15 to rotate, causing the worm wheel 15 to rotate the inner tube 7. This drive mechanism controls the rotation of the inner tube 7. Simultaneously, the unidirectional transmission structure formed by the worm gear 16 and the worm wheel 15 enables the rotation of the inner tube 7 to achieve a self-locking function, preventing the inner tube 7 from rotating automatically.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
