Description

Technical Field

[0001] The present invention relates to the technical field of clean room compartment ceiling equipment, in particular to assembled clean room compartment ceiling equipment with variable controllability and adjustment. Background Art

[0002] During the construction and operation of cleanrooms, ceiling systems are a key component in maintaining a clean environment. Their performance directly affects the efficiency of the entire cleanroom. Traditional cleanroom ceiling systems have relatively simple functions, often only providing basic lighting or ventilation functions, and are unable to meet the needs of modern cleanrooms for diversified functions and efficient cleanliness maintenance.

[0003] On the one hand, existing suspended ceiling equipment lacks effective adjustment methods when dealing with different usage scenarios. For example, in some clean room operation processes that have special requirements for air flow direction and speed, traditional suspended ceiling equipment cannot flexibly change the airflow path and flow rate, resulting in uneven indoor air circulation, affecting product quality or the accuracy of experimental results. On the other hand, existing equipment also has obvious defects in the clean maintenance of internal channels. After long-term operation, dust, microorganisms and other pollutants are prone to accumulate in the internal channels, which not only reduces ventilation efficiency, but may also cause secondary pollution to the clean room environment. Moreover, when it is necessary to switch the equipment function, the connection status of the internal channel cannot be easily adjusted, making it difficult for the equipment to quickly adapt to the new working mode, increasing the maintenance cost and downtime of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide an assembled variably controllable clean room ceiling device to solve the problems of traditional clean room ceiling devices mentioned in the above background technology, such as single function, lack of adjustment means and difficulty in maintaining the cleanliness of internal channels.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: an assembled, variably controlled and adjustable clean room partition ceiling device, comprising a base, a UV lamp fixedly mounted on the lower surface of the base, and an adjustable diversion mechanism disposed within the base. By switching the connection state of the internal channel of the base, different functions can be applied while ensuring the cleanliness of the internal channel;

[0006] The regulating and diverting mechanism includes: a displacement seat, which is slidably mounted inside the base, and an air exchange port is provided on the outer surface of the upper end of the displacement seat, a rotating fan blade is installed inside the displacement seat, and a cleaning rod is fixedly provided on the outer surface of the upper end of the rotating shaft of the fan blade, a filter disk is fixedly provided on the inner surface of the displacement seat between the lower surface of the cleaning rod and the side surface of the fan blade, an exhaust port is provided on the lower end side surface of the displacement seat, a motor is fixedly mounted inside the upper end of the base, and the lower end of the output shaft of the motor is fixedly connected to the displacement rod, the lower end of the displacement rod is fixedly connected to a connecting column, and a sliding clamping rod is installed on the lower end of the connecting column, and a clamping slot is provided on the upper end of the rotating shaft of the fan blade;

[0007] The regulating and diverting mechanism further includes: a fixed plate, the fixed plate being fixedly arranged on the upper end surface of the displacement seat, and a contact column being fixedly arranged on the upper surface of the fixed plate, a magnetic block being fixedly arranged on the inner top surface of the base, an extrusion plate being fixedly arranged on the outer surface of the upper end of the displacement rod, and a rotating extrusion plate being installed on the lower surface of the extrusion plate, and a resistance column being fixedly arranged on the lower surface of the extrusion plate on one side of the extrusion plate;

[0008] The air inlet and outlet pipes are fixedly provided on the inner surfaces of both sides of the upper end of the base respectively, and a rotating switching barrel is installed inside the lower end of the base on which the air inlet pipe is located, and the outer surface of the switching barrel is provided with an air outlet and an air inlet, and a partition plate is fixedly provided on the inner surface of the switching barrel, and a transmission gear is fixedly provided on the outer surfaces of both ends of the switching barrel, and a transmission gear rod is fixedly provided on the outer surfaces of both ends of the displacement seat, a storage box is embedded in the lower end surface of the base, and a partition block is fixedly provided on the inner surface of the storage box, an air jet groove is provided inside the lower surface of the base, and a guide port is provided inside the base between the air jet groove and the switching barrel;

[0009] An installation cavity is provided inside the lower end of the base, and a clearance cavity is provided inside the base on one side of the installation cavity. A guide plate is fixedly provided at the lower end of the displacement seat, and a connection port is provided on the inner surface of the lower end of the guide plate. A press switch is fixedly installed on the inner bottom surface of the installation cavity, an air pump is fixedly installed inside the clearance cavity, and an air suction groove is provided inside the lower surface of the base.

[0010] Preferably, the displacement seat is threadedly connected to the displacement rod, and the outer surface of the upper end of the displacement rod is a smooth surface, and the diameter of the smooth surface of the upper end of the displacement rod is smaller than the diameter of the end of the displacement rod with a thread, and the lower surface of the cleaning rod is provided with bristles, and the bristles on the lower surface of the cleaning rod are in contact with the upper surface of the filter plate.

[0011] Using the above technical solution, when the motor drives the displacement rod to rotate, the displacement rod can drive the displacement seat to slide up and down in the base through a threaded connection, thereby adjusting the connection status of the internal channels of the equipment. At the same time, during the rotation of the fan blades, the cleaning rod can rotate synchronously, and the bristles on its lower surface clean the filter plate, effectively preventing the filter plate from being blocked by dust and other pollutants, thereby ensuring the filtering effect and ventilation efficiency.

[0012] Preferably, a spring is connected between the connecting column and the card rod, and the card rod is located directly above the card slot, and the vertical projection of the card rod completely overlaps with the vertical projection of the card slot.

[0013] By adopting the above technical solution, when the displacement seat and the displacement rod are disengaged from the threaded connection and are adsorbed by the magnetic block, the clamping rod can accurately fall into the clamping slot under the action of the spring, so that the fan blades can rotate synchronously when the motor rotates, ensuring that the fan blades can work normally during the air intake process of the equipment and realize air intake.

[0014] Preferably, the contact columns are evenly distributed on the upper surface of the fixed disk, and the upper ends of the contact columns are hemispherical in design. The magnetic block is located directly above the fixed disk. A spring is connected between the extrusion plate and the extrusion disk, and the contact columns and the extrusion plate are arranged in a one-to-one correspondence.

[0015] By adopting the above technical solution, during the movement of the displacement seat, the extrusion plate rotates with the displacement rod. When the extrusion plate contacts the contact column, it will be squeezed and rotated and compress or stretch the spring. Through the expansion and contraction of the spring and the support of the resistance column, the position change of the displacement seat is accurately controlled, thereby realizing the switching of the internal channel connection status of the equipment, and at the same time, it can also ensure the stability of the displacement seat in different positions.

[0016] Preferably, the lower ends of the air inlet duct and the air outlet duct are both provided with openings, and the openings at the lower ends of the air inlet duct and the air outlet duct are both arranged toward the displacement seat, and the openings at the lower ends of the air inlet duct and the air outlet duct are staggered up and down, the openings at the lower ends of the air inlet duct and the air outlet duct are fitted with the outer surface of the displacement seat, the outer surface of the switching barrel is fitted with one end of the guide port, and the other end of the guide port is connected to the upper end of the jet slot, and the lower end of the jet slot is provided with a hole that passes through the lower surface of the base, the air outlet and the air inlet are respectively located on the outer surfaces of the switching barrel on both sides of the partition plate, and the ends of the air outlet and the air inlet facing the outside of the switching barrel are fitted with the inner surface of the base.

[0017] By adopting the above technical solution, when the displacement seat moves, the connectivity status of the air inlet duct, the air outlet duct and the air exchange port on the displacement seat can be accurately controlled. At the same time, the rotation of the switching barrel can change the position of the air inlet and the air outlet, thereby realizing the switching of different air flow paths, so that the external air passes through the air inlet duct, the displacement seat, and the switching barrel and is ejected from the jet slot, or the air in the clean room is discharged through the air suction slot, the displacement seat, and the air outlet duct, thereby meeting different ventilation needs.

[0018] Preferably, the transmission gear and the switching barrel are concentrically arranged, and the transmission gear is meshed with the transmission gear rod, the storage box is fixed to the base by bolts, the upper end face of the dividing block is arc-shaped, and the arc surface of the upper end of the dividing block is concentrically arranged with the switching barrel, and a gap is left between the lower end of the dividing block and the inner bottom surface of the storage box, a notch is provided on the outer surface of the switching barrel facing the upper end of the storage box, and one end of the dividing plate is located inside the notch on the surface of the switching barrel.

[0019] With the above technical solution, when the displacement seat moves, the transmission gear is driven to rotate through the transmission gear rod, thereby causing the switching barrel to rotate synchronously to realize the switching of the air flow channel. The storage box is connected with bolts for easy installation and disassembly. The design of the partition block allows the air to fully contact with the functional materials filled inside when passing through the storage box, thereby further processing the air. By replacing the storage boxes with different materials, the different functional requirements of the clean room can be met.

[0020] Preferably, the guide plate is located inside the mounting cavity, and the outer surface of the guide plate fits with the inner surface of the mounting cavity. The guide plate is hollow in design, and the internal cavity of the guide plate is connected with the internal cavity of the displacement seat. The lower end surface of the guide plate fits with the upper end of the push switch. The connecting port is arranged opposite to the give way cavity, and the give way cavity is connected with the internal cavity of the guide plate through the connecting port. The air inlet end of the air pump is connected with one end of the air suction groove, and the air outlet end of the air pump is located inside the give way cavity. The lower end of the air suction groove is provided with a hole that passes through the lower surface of the base.

[0021] Using the above technical solution, when the displacement seat moves downward, the guide plate moves accordingly and squeezes the press switch. At the same time, the connecting port is connected to the give way cavity. After starting the air pump, the air pump can suck the air in the clean room through the suction groove and enter the displacement seat through the guide plate. During the air flow process, it drives the fan blades to rotate, and uses the cleaning rod to clean the dust and impurities on the filter plate and discharge them with the air to achieve cleaning of the internal channel.

[0022] Compared with the prior art, the present invention has the following beneficial effects: the assembled variably controllable clean room partition ceiling device:

[0023] 1. With a unique adjustment and diversion mechanism consisting of a displacement base, motor, and displacement rod, this ceiling system can flexibly switch the internal channel connection status. In different usage scenarios, it can accurately adjust the airflow path and flow rate according to the requirements of the air flow direction. The motor drives the displacement rod to move the displacement base to switch the channel connection, ensuring that indoor air can flow in the predetermined direction, meeting the diverse functional requirements of modern clean rooms.

[0024] 2. When the air is inlet, the filter disc in the diversion mechanism is adjusted to effectively intercept dust and other pollutants. When the fan blades rotate, the cleaning rod is driven to clean the filter disc to prevent the accumulation of pollutants and blockage. When the air is exhausted, the airflow drives the fan blades and the cleaning rod to rotate, so that dust and other pollutants can be carried away and discharged with the airflow, avoiding the accumulation of dust, microorganisms and other pollutants in the internal channels after long-term operation, maintaining high ventilation efficiency, eliminating secondary pollution, and ensuring the high cleanliness of the clean room environment;

[0025] 3. The storage box adopts an assembled structure, and the installation and disassembly process is simple. When the functional requirements of the clean room change, the storage box can be quickly removed and replaced to achieve fast and flexible transformation. The storage box can be replaced with a storage box with different fillers built in, so as to facilitate functional upgrades to meet the needs of use in different periods.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0038] See also Figures 1-10 The present invention provides a technical solution: an assembled clean room compartment ceiling device with variable control and adjustment. Example

[0039] This embodiment discloses: a base 1, a UV lamp 2 is fixedly mounted on the lower surface of the base 1, and an adjusting and diverting mechanism is provided inside the base 1. By switching the connection state of the internal channel of the base 1, different functions can be applied and the cleanliness of the internal channel can be ensured;

[0040] The regulating and diversion mechanism includes: a displacement seat 3, which is slidably mounted inside the base 1, and a ventilation port 4 is provided on the outer surface of the upper end of the displacement seat 3, a rotating fan blade 5 is installed inside the displacement seat 3, and a cleaning rod 6 is fixedly provided on the outer surface of the upper end of the rotating shaft of the fan blade 5, a filter disc 7 is fixedly provided on the inner surface of the displacement seat 3 between the lower surface of the cleaning rod 6 and the side surface of the blade of the fan blade 5, an exhaust port 8 is provided on the lower end side surface of the displacement seat 3, a motor 9 is fixedly mounted inside the upper end of the base 1, and a displacement rod 10 is fixedly connected to the lower end of the output shaft of the motor 9, the lower end of the displacement rod 10 is fixedly connected to a connecting column 11, and a sliding clamping rod 12 is installed on the lower end of the connecting column 11, and a clamping slot 13 is provided on the upper end of the rotating shaft of the fan blade 5;

[0041] The regulating and diverting mechanism further includes: a fixed disk 14, which is fixedly mounted on the upper end surface of the displacement seat 3, and a contact column 15 is fixedly mounted on the upper surface of the fixed disk 14, a magnetic block 16 is fixedly mounted on the inner top surface of the base 1, an extrusion disk 17 is fixedly mounted on the outer surface of the upper end of the displacement rod 10, and a rotating extrusion plate 18 is mounted on the lower surface of the extrusion disk 17, and an abutment column 19 is fixedly mounted on the lower surface of the extrusion disk 17 on one side of the extrusion plate 18;

[0042] The displacement seat 3 is threadedly connected to the displacement rod 10, and the outer surface of the upper end of the displacement rod 10 is smooth, and the diameter of the smooth surface of the upper end of the displacement rod 10 is smaller than the diameter of the end of the displacement rod 10 provided with the thread. The lower surface of the cleaning rod 6 is provided with bristles, and the bristles on the lower surface of the cleaning rod 6 are in contact with the upper surface of the filter disc 7.

[0043] A spring is connected between the connecting column 11 and the card rod 12, and the card rod 12 is located directly above the card slot 13, and the vertical projection of the card rod 12 completely coincides with the vertical projection of the card slot 13;

[0044] The contact posts 15 are evenly distributed on the upper surface of the fixed disk 14, and the upper ends of the contact posts 15 are hemispherical. The magnetic block 16 is located directly above the fixed disk 14. A spring is connected between the extrusion plate 18 and the extrusion disk 17. The contact posts 19 and the extrusion plates 18 are arranged in a one-to-one correspondence.

[0045] When disinfection is needed, the ultraviolet lamp 2 can be turned on to disinfect and sterilize through an external control switch. When the displacement seat 3 needs to be moved to control and adjust the channel, the motor 9 at the upper end of the base 1 is started, and the motor 9 drives the displacement rod 10, the connecting column 11 and the clamping rod 12 to rotate. At this time, the displacement rod 10 drives the displacement seat 3 to slide up and down inside the base 1 through the threaded connection with the displacement seat 3 until the displacement seat 3 is disengaged from the threaded connection with the surface of the displacement rod 10. At this time, the displacement seat 3 is attracted by the magnetic block 16, and will not fall down under the action of neutrality even if it is disengaged from the threaded connection with the displacement rod 10. At the same time, the clamping rod 12 is supported by the spring and is stuck in the clamping groove 13, so that the motor 9 can drive the fan blades 5 to rotate. The fan blades 5 draw in external air through the ventilation port 4 and filter it through the filter disc 7. The filtered air is discharged through the exhaust port 8, and the cleaning rod 6 cleans the filter disc 7 through the bristles during the rotation to prevent the filter disc 7 from being blocked.

[0046] During the air intake process, the extrusion plate 17 is driven by the displacement rod 10 to rotate forward. At this time, the extrusion plate 18 is squeezed and rotated when it contacts the contact column 15 on the fixed plate 14, compressing the spring between the extrusion plate 17 until the extrusion plate 18 completely passes the contact column 15. When air intake is not needed, the extrusion plate 17 is driven by the displacement rod 10 to rotate in the opposite direction. At this time, the extrusion plate 18 is squeezed and rotated when it contacts the contact column 15 on the fixed plate 14, stretching the spring between the extrusion plate 17 until the extrusion plate 18 is completely in contact with the interference column 19 on the other side. At this time, the interference column 19 supports the extrusion plate 18 so that the extrusion plate 18 cannot continue to rotate, so that the extrusion plate 18 pushes the displacement seat 3 downward through the contact column 15 and the fixed plate 14. At this time, the displacement seat 3 is disengaged from the adsorption of the magnetic block 16 and restores the connection with the threaded surface of the displacement rod 10. The displacement rod 10 drives the displacement seat 3 to slide downward, causing the displacement seat 3 to slide down until the displacement seat 3 is reset. Example

[0047] This embodiment is disclosed on the basis of the first embodiment: an air inlet pipe 20 and an air outlet pipe 21 are fixedly provided on the inner surfaces of both sides of the upper end of the base 1, a rotating switching barrel 22 is installed inside the lower end of the base 1 on which the air inlet pipe 20 is located, and an air outlet 23 and an air inlet 24 are provided on the outer surface of the switching barrel 22, and a partition plate 25 is fixedly provided on the inner surface of the switching barrel 22, a transmission gear 26 is fixedly provided on the outer surfaces of both ends of the switching barrel 22, and a transmission gear rod 27 is fixedly provided on the outer surfaces of both ends of the displacement seat 3, a storage box 28 is embedded in the lower end surface of the base 1, and a partition block 29 is fixedly provided on the inner surface of the storage box 28, an air jet groove 30 is provided inside the lower surface of the base 1, and a guide port 31 is provided inside the base 1 between the air jet groove 30 and the switching barrel 22;

[0048] The lower ends of the air inlet duct 20 and the air outlet duct 21 are both provided with openings, and the openings at the lower ends of the air inlet duct 20 and the air outlet duct 21 are both arranged toward the displacement seat 3, and the openings at the lower ends of the air inlet duct 20 and the air outlet duct 21 are arranged in an upper and lower staggered manner, and the openings at the lower ends of the air inlet duct 20 and the air outlet duct 21 are fitted with the outer surface of the displacement seat 3, the outer surface of the switching barrel 22 is fitted with one end of the guide port 31, and the other end of the guide port 31 is connected with the upper end of the air jet slot 30, and the lower end of the air jet slot 30 is provided with a hole that passes through the lower surface of the base 1, the air outlet 23 and the air inlet 24 are respectively located on the outer surface of the switching barrel 22 on both sides of the partition plate 25, and the ends of the air outlet 23 and the air inlet 24 facing the outside of the switching barrel 22 are fitted with the inner surface of the base 1;

[0049] The transmission gear 26 is concentrically arranged with the switching barrel 22, and the transmission gear 26 is meshed with the transmission gear rod 27. The storage box 28 is fixed to the base 1 by bolts. The upper end surface of the partition block 29 is arc-shaped, and the arc surface of the upper end of the partition block 29 is concentrically arranged with the switching barrel 22. There is a gap between the lower end of the partition block 29 and the inner bottom surface of the storage box 28. A notch is provided on the outer surface of the switching barrel 22 facing the upper end of the storage box 28, and one end of the partition plate 25 is located inside the notch on the surface of the switching barrel 22.

[0050] When the displacement seat 3 is driven to move upward, the air exchange port 4 on one side of the displacement seat 3 coincides with the air inlet duct 20, while the air exchange port 4 on the other side of the displacement seat 3 is misaligned with the air outlet duct 21. At the same time, the displacement seat 3 drives the transmission gear 26 to rotate through the transmission gear rod 27 fixed on its side surface, and the transmission gear 26 drives the switching barrel 22 to rotate, so that the air inlet 24 faces the exhaust port 8 and the air outlet 23 faces the guide port 31. At this time, the air inhaled by the fan blades 5 through the air inlet duct 20 and the air exchange port 4 is injected into the jet slot 30 through the exhaust port 8, the air inlet 24, the air outlet 23 and the switching barrel 22 in turn. The jet slot 30 sprays the air into the clean room through the holes to achieve the introduction of fresh air.

[0051] At the same time, when the air enters the switching barrel 22 through the air inlet 24, the lower end of the partition plate 25 is just in contact with the upper end of the partition block 29, so that the air must pass through the gap between the lower end of the partition block 29 and the storage box 28 to flow into the other side of the partition plate 25. By filling the partition block 29 with functional materials, such as sterilization filter element materials, further processing of the air can be achieved. At the same time, by quickly replacing the storage box 28, it can adapt to different work scene requirements. Example

[0052] This embodiment is based on the first and second embodiments. A mounting cavity 32 is defined within the lower end of the base 1, and a clearance cavity 33 is defined within the base 1 on one side of the mounting cavity 32. A guide plate 34 is fixedly provided at the lower end of the displacement seat 3, and a connection port 35 is defined on the inner surface of the lower end of the guide plate 34. A press switch 36 is fixedly provided on the bottom surface of the mounting cavity 32, an air pump 37 is fixedly provided within the clearance cavity 33, and an air suction groove 38 is defined within the lower surface of the base 1.

[0053] The guide plate 34 is located inside the mounting cavity 32, and the outer surface of the guide plate 34 is in contact with the inner surface of the mounting cavity 32. The guide plate 34 is hollow, and the inner cavity of the guide plate 34 is connected to the inner cavity of the displacement seat 3. The lower end surface of the guide plate 34 is in contact with the upper end of the press switch 36. The connecting port 35 is arranged opposite the clearance cavity 33, and the clearance cavity 33 is connected to the inner cavity of the guide plate 34 through the connecting port 35. The air inlet end of the air pump 37 is connected to one end of the air suction groove 38, and the air outlet end of the air pump 37 is located inside the clearance cavity 33. The lower end of the air suction groove 38 is provided with a hole that penetrates the lower surface of the base 1.

[0054] When the displacement seat 3 is driven to move downward, the air exchange port 4 on one side of the displacement seat 3 coincides with the air inlet and outlet ducts 21, while the air exchange port 4 on the other side of the displacement seat 3 is misaligned with the air inlet duct 20. At the same time, the displacement seat 3 drives the transmission gear 26 to rotate through the transmission gear rod 27 fixed to its side surface, and the transmission gear 26 drives the switching barrel 22 to rotate, so that the air inlet 24 is misaligned with the exhaust port 8 and the air outlet 23 is misaligned with the guide port 31. At this time, the fan blade 5 is also disconnected from the clamping rod 12 and no longer rotates.

[0055] At this time, as the displacement seat 3 moves downward, the lower end of the guide plate 34 penetrates into the interior of the installation cavity 32 to squeeze the press switch 36. At the same time, the connecting port 35 is connected to the yield cavity 33, and the air pump 37 is started. The air pump 37 sucks the air suction groove 38 through the air inlet end so that the air suction groove 38 sucks the air in the clean room through the holes at the lower end. The air is discharged to the interior of the yield cavity 33 through the air outlet end of the air pump 37 and passes through the connecting port 35 and the guide plate 34 and then enters the displacement seat 3. After the fan blades 5 rotate, the air is discharged upward through the fan blades 5 and the fan blades 5. During the process, the fan blades 5 use the brush on the lower surface of the cleaning rod 6 to clean and lift up the dust and impurities on the filter disc 7, so that the dust and impurities can be better discharged with the air.

[0056] The above specific embodiments further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
