Description

Technical Field

[0001] This utility model relates to a rectifier-type air supply device for biological laboratories, belonging to the technical field of air supply devices. Background Technology

[0002] Existing air conditioning systems in biological laboratories employ vortex ring generators to optimize airflow distribution and improve airflow delivery. However, this system also presents several significant challenges: Firstly, the gas velocity is entirely dependent on the piston pusher. Achieving different gas propagation speeds requires complex control of the piston pusher's movement, making the entire system overly complex. This not only increases manufacturing and maintenance costs but also reduces system stability. Secondly, the precision of controlling airflow uniformity is low, failing to meet the stringent requirements of biological laboratories for uniform airflow distribution.

[0003] It is evident that existing air conditioning systems for biological laboratories are deficient in terms of structural rationality and airflow uniformity control. Therefore, this application proposes a rectifier-type air conditioning system for biological laboratories to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing air conditioning supply devices for biological laboratories in terms of structural rationality and airflow uniformity control, and to provide a rectifier-type air conditioning supply device for biological laboratories.

[0005] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution: A rectifier-type air supply device for biological laboratories includes: An external air supply pipe is provided, an internal air supply pipe is provided inside the external air supply pipe, a main air supply assembly is provided inside the internal air supply pipe, an adjustment assembly is provided at the air outlet of the main air supply assembly, and an air inlet assembly is provided on the adjustment assembly to divert the airflow between the interlayer of the external air supply pipe and the internal air supply pipe to the main air supply assembly. The air supply end of the external air supply pipe is equipped with a rectifier; the other end of the main air supply component is equipped with a propulsion component, which is used to direct the airflow into the rectifier.

[0006] Optionally, the main air supply assembly includes a main air supply duct, an air propulsion chamber is provided at one end of the main air supply duct near the propulsion assembly, a magnetic propulsion plate is provided in the air propulsion chamber, and a rectifier is provided at the other end of the main air supply duct away from the air propulsion chamber.

[0007] Optionally, the propulsion assembly includes a first motor, which is connected to the inner wall of the air supply duct via a bracket. The first motor is connected to a rotating shaft, and a propulsion rod is provided on the rotating shaft. The end of the propulsion rod is provided with a permanent magnet that cooperates with the magnetic propulsion plate.

[0008] Optionally, the adjustment assembly includes a rotating sleeve rotatably connected to the air outlet of the main air supply assembly and a second motor. The rotating sleeve is provided with a first air inlet at intervals, and the rotating sleeve is provided with a connecting frame. The output shaft of the second motor is connected to the connecting frame.

[0009] Optionally, the air intake assembly includes an air intake sleeve, which has a second air intake corresponding to the first air intake. The second air intake has a support plate, and the support plate has a mounting hole, which has a rectifier.

[0010] Optionally, the rectifier includes a connecting bracket, a mounting bushing, a shape memory alloy spring, and a rectifier sleeve. The connecting bracket is disposed in the mounting hole, the mounting bushing is disposed on the connecting bracket, the shape memory alloy spring is disposed on the top of the mounting bushing, and the rectifier sleeve is sleeved on the mounting bushing and connected to the shape memory alloy spring.

[0011] Optionally, the rectifier sleeve is equipped with a wind speed sensor to detect the airflow speed in the main air supply assembly. The controller regulates the current of the memory alloy spring through the airflow speed, thereby driving the memory alloy spring to extend and retract.

[0012] Optionally, the rectifier assembly includes a conical nozzle and a rectifier plate, the rectifier plate being disposed inside the conical nozzle, and the conical nozzle being connected to the air outlet of the external air supply pipe.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: 1. Breaking through the limitations of traditional air resistance rectifiers that rely on airflow self-regulation, this device monitors airflow speed in real time through a wind speed sensor and adjusts the current of the shape memory alloy spring accordingly. This drives the adjustment cover to move up and down to change the air resistance at the mounting hole. Even when the airflow in the air supply duct is small, it can still accurately adjust the air resistance distribution, ensuring that the air supply device can achieve uniform and stable air supply under different airflow conditions (high and low airflow rates). This significantly improves the adaptability of the air supply device to the complex air supply needs of biological laboratories. 2. The main air supply component, regulating component and air intake component are integrated into one unit. All components work together, eliminating the need for complex branch pipelines or redundant control structures. The overall structure is simplified, reducing the installation and maintenance costs of the air supply device. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0018] like Figures 1-3 As shown, a rectifier-type air supply device for biological laboratories is disclosed, comprising: An external air supply pipe 1 is provided, an internal air supply pipe 2 is provided inside the external air supply pipe 1, a main air supply assembly 3 is provided inside the internal air supply pipe 2, an adjustment assembly 5 is provided at the air outlet of the main air supply assembly 3, and an air inlet assembly 6 is provided on the adjustment assembly 5 to divert the airflow between the interlayer of the external air supply pipe 1 and the internal air supply pipe 2 to the main air supply assembly 3. The air supply end of the external air supply pipe 1 is provided with a rectifier component 7; the other end of the main air supply component 3 is provided with a propulsion component 4, which is used to direct the airflow into the rectifier component 7.

[0019] The air conditioning air in the biological laboratory first enters the space between the outer air supply pipe 1 and the inner air supply pipe 2, and then enters the device through the air intake assembly 6. The air is initially diverted and guided into the main air supply assembly 3. At this time, the propulsion assembly 4 is activated to push the airflow to flow in a direction within the main air supply assembly 3. The internal rectifier 302 performs preliminary rectification of the airflow to reduce turbulence.

[0020] In the specific implementation process of this embodiment, such as Figures 4-5 As shown, the main air supply assembly 3 includes a main air supply duct 301. An air propulsion chamber 303 is provided at one end of the main air supply duct 301 near the propulsion assembly 4. A magnetic propulsion plate 304 is provided inside the air propulsion chamber 303. A rectifier 302 is provided at the other end of the main air supply duct 301 away from the air propulsion chamber 303. The surface of the main air supply duct 301 is connected to the inner wall of the inner air supply duct 2 via a bracket. At least two air propulsion chambers 303 are provided, each with a magnetic propulsion plate 304. The magnetic propulsion plate 304 is formed by an elastic membrane disposed inside the air propulsion chamber 303. Figure 6As shown, the propulsion assembly 4 includes a first motor 402, which is connected to the inner wall of the air supply duct 2 via a bracket. The first motor 402 is connected to a rotating shaft 403, and the other end of the rotating shaft 403 is provided with a mounting bracket 401. The rotating shaft and the mounting bracket 401 are rotatably connected. The mounting bracket 401 is connected to the inner wall of the air supply duct 2 via a bracket. A propulsion rod 404 is provided on the rotating shaft 403. The end of the propulsion rod 404 is provided with a permanent magnet 405 that cooperates with the magnetic propulsion plate 304. The first motor 402 drives the propulsion rod 404 to rotate via the rotating shaft 403. The permanent magnet block 405 at the end of the propulsion rod 404 generates magnetic linkage with the magnetic propulsion plate 304 in the air propulsion chamber 303, which pushes the airflow to flow in a direction within the main air supply duct 301. The rectifier 302 performs preliminary rectification of the airflow to reduce turbulence.

[0021] In the specific implementation process of this embodiment, such as Figure 7 As shown, the adjustment component 5 includes a rotating sleeve 503 rotatably connected to the air outlet of the main air supply component 3 and a second motor 501. The rotating sleeve 503 is provided with a first air inlet 504 at intervals. The rotating sleeve 503 is provided with a connecting frame 502. The output shaft of the second motor 501 is connected to the connecting frame 502. The second motor 501 is fixedly connected to the inner air supply pipe 2 through a bracket.

[0022] In the specific implementation process of this embodiment, such as Figures 7-8 As shown, the air intake assembly 6 includes an air intake sleeve 601, on which a second air intake hole 602 corresponding to the first air intake hole 504 is provided. A support plate 603 is provided on the second air intake hole 602, and a mounting hole 604 is formed on the support plate 603. A rectifier 605 is provided in the mounting hole 604. Figure 9 As shown, the rectifier 605 includes a connecting bracket 6051, a mounting sleeve 6052, a shape memory alloy spring 6053, and a rectifier sleeve 6054. The connecting bracket 6051 is disposed in the mounting hole 604, the mounting sleeve 6052 is disposed on the connecting bracket 6051, the shape memory alloy spring 6053 is disposed on the top of the mounting sleeve 6052, and the rectifier sleeve 6054 is sleeved on the mounting sleeve 6052 and connected to the shape memory alloy spring 6053. The rectifier sleeve 6054 is equipped with a wind speed sensor 6055 for detecting the airflow speed in the main air supply assembly 3. The controller regulates the current of the shape memory alloy spring 6053 through the airflow speed, driving the shape memory alloy spring 6053 to extend and retract. When the shape memory alloy spring 6053 extends, it rises, the rectifier sleeve 6054 moves upward, and the ventilation volume of the second air inlet 602 increases; when the shape memory alloy spring 6053 retracts, it descends, the rectifier sleeve 6054 moves downward, and the ventilation volume of the second air inlet 602 decreases.

[0023] like Figure 10As shown, the rectifier assembly includes a conical nozzle 701 and a rectifier plate 702. The rectifier plate is disposed inside the conical nozzle 701, and the conical nozzle 701 is connected to the air outlet of the external air supply pipe 1.

[0024] The working principle of this utility model: Air from the biological laboratory's air conditioning system first enters the space between the outer air supply duct 1 and the inner air supply duct 2, and then enters the device through the air intake assembly 6. The second air intake hole 602 on the air intake sleeve 601 guides the initial airflow. The support plate 603 guides the airflow into the conical nozzle 701 through the mounting hole 604. At this time, the propulsion assembly 4 is activated: the first motor 402 drives the propulsion rod 404 to rotate through the rotating shaft 403. The permanent magnet block 405 at the end of the propulsion rod 404 interacts with the magnetic propulsion plate 304 in the air propulsion chamber 303. (The magnetic propulsion plate 304 is made of an elastic membrane set inside the air propulsion cavity 303) generates magnetic linkage, which pushes the airflow to flow in a direction within the main air supply duct 301. The rectifier 302 performs preliminary rectification of the airflow to reduce turbulence. To further explain, the propulsion rod 404 simply pulls the magnetic propulsion plate 304 through magnetic force. The magnetic propulsion plate 304 is connected to the elastic membrane. When the stretching force of the elastic membrane is greater than the magnetic force, 304 will separate from 404 and then rebound, pushing the airflow forward.

[0025] Airflow regulation and air resistance control stage: Regulation component 5 controls the opening and closing of air intake: The second motor 501 drives the rotating sleeve 503 to rotate through the connecting bracket 502. The relative position of the first air intake hole 504 on the rotating sleeve 503 and the second air intake hole 602 on the air intake sleeve 601 changes. By controlling the rotation of the first air intake hole 504 and the second air intake hole 602, the flow channel is opened intermittently. When the two overlap, the flow channel is open; when they do not overlap, the flow channel is closed. At the same time, the rectifier 605 starts active regulation: The wind speed sensor 6055 monitors the airflow speed in the main air supply duct 301 in real time. Based on the monitoring data, the current of the shape memory alloy spring 6053 is regulated. The shape memory alloy spring 6053 is fixed to the connecting bracket 6051 through the mounting sleeve 6052. Its length expands and contracts with the change of current, driving the rectifier sleeve 6054 to move up and down, changing its relative position with the mounting hole 604, thereby dynamically adjusting the air resistance distribution and ensuring that the airflow uniformity can still be maintained under low airflow conditions.

[0026] Rectification and uniform air supply stage: The airflow delivered by the main air supply duct 301 enters the rectifier assembly 7. The conical nozzle 701 accelerates and concentrates the airflow. The rectifier plate 702 further straightens the airflow direction and eliminates residual turbulence. Finally, the airflow after multi-layer rectification diffuses into the biological laboratory environment through the interlayer space between the inner air supply duct 2 and the outer air supply duct 1, achieving uniform air supply throughout the entire area.

[0027] Throughout the air supply process, the regulating component 5 and the rectifier 605 continuously respond to the feedback signal from the wind speed sensor 6055: when the airflow speed fluctuates, the shape memory alloy spring 6053 adjusts the position of the rectifier sleeve 6054 in real time, and in conjunction with the air intake adjustment of the rotating sleeve 503, ensures that the device can operate stably under high and low airflow conditions, meeting the stringent requirements of biological laboratories for airflow uniformity.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
