Description

Technical Field

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

[0002] Most existing air conditioning systems in biological laboratories use fixed-speed rotary motors to drive air supply devices, combined with traditional duct designs to achieve airflow. However, this method leads to temperature differences between the top and bottom of the biological laboratory space, resulting in samples at different heights being in different temperature environments. This problem affects the activity, metabolic rate, or reaction efficiency of the samples, ultimately causing distortion of experimental sample data, poor experimental repeatability, and unreliable conclusions. In the process of technological improvement of air conditioning air supply devices, in order to ensure the stability of airflow during air supply, the industry generally adopts air resistance rectifiers to adjust the internal air resistance of the device to achieve a uniform and stable air supply effect. However, the working state adjustment of existing air resistance rectifiers depends on the airflow itself inside the air supply device. When the airflow rate inside the device is low, the airflow cannot effectively drive the air resistance rectifier to complete the state adjustment. This directly leads to the air resistance rectifier being unable to function under low airflow conditions, and thus failing to guarantee the uniform and stable air supply of the air supply device. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-efficiency air supply device for biological laboratories. This invention addresses the problem that the working state adjustment of existing air resistance rectifiers depends on the airflow itself inside the air supply device. When the airflow rate inside the device is low, the airflow cannot effectively drive the air resistance rectifier to complete the state adjustment. This directly leads to the air resistance rectifier being unable to function under low airflow conditions, and thus cannot guarantee the uniform and stable air supply of the air supply device.

[0004] To achieve the above objectives / to solve the above technical problems, this utility model adopts the following technical solution: A high-efficiency air supply device for biological laboratories, comprising: An air supply housing, wherein the top of the air supply housing is provided with an air supply mechanism, the middle is provided with an adaptive air resistance adjustment component, and the bottom is provided with a flow interception mechanism; The adaptive air resistance adjustment component includes a mounting plate connected to the air supply housing, an air supply pipe spaced apart on the mounting plate, and an air resistance adjustment component inside the air supply pipe; The flow-cutting mechanism includes a mounting rod, an upper flow-cutting plate, and a lower flow-cutting plate. The mounting rod is installed on the inner wall of the air supply housing. The mounting rod is equipped with a motor. The motor is connected to the upper flow-cutting plate and the lower flow-cutting plate through a transmission shaft. The upper flow-cutting plate and the lower flow-cutting plate are provided with air guide holes.

[0005] Optionally, the air guide holes of the upper and lower interceptor plates are offset at a preset angle during installation. When the air guide hole of the lower interceptor plate opens the air outlet of the air supply pipe, the air guide hole of the upper interceptor plate moves synchronously to the air inlet of the air supply pipe.

[0006] Optionally, the air resistance regulating component includes an adjusting mounting plate, the adjusting mounting plate having evenly spaced mounting holes, and an air direction adjusting mechanism being provided within the mounting holes.

[0007] Optionally, the wind direction adjustment mechanism includes a support frame disposed in the mounting hole, a mounting sleeve disposed on the support frame, an adjustment cover disposed on the outside of the mounting sleeve, a memory alloy spring disposed inside the mounting sleeve, and a wind speed sensor disposed on the top of the adjustment cover.

[0009] Optionally, the air supply mechanism includes a mounting cover and a blower, wherein the mounting cover has a through hole for installing the blower, and the blower is located at the through hole.

[0010] Optionally, at least four blowers are provided.

[0011] Optionally, the air guide hole is configured as an arc shape.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This invention overcomes the limitations of traditional air resistance rectifiers that rely on airflow self-regulation. The wind speed sensor in this invention monitors the airflow speed in real time and adjusts the current of the shape memory alloy spring accordingly, driving the adjustment cover to move up and down to change the air resistance at the mounting hole. This active adjustment method can accurately adjust the air resistance distribution even when the airflow in the air supply duct is small, ensuring that the air supply device can achieve uniform and stable air supply under different airflow conditions, significantly improving the adaptability of the air supply device to complex air supply requirements.

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0017] like Figures 1-7 As shown, a high-efficiency air supply device for a biological laboratory is disclosed, comprising: The air supply housing 1 has an air supply mechanism 2 at the top, an adaptive air resistance adjustment component 3 in the middle, and a flow interception mechanism 4 at the bottom. like Figures 3-4As shown, the adaptive air resistance adjustment component 3 includes a mounting plate 301 connected to the air supply housing 1, an air supply pipe 302 is provided on the mounting plate 301 at intervals, and an air resistance adjustment component 303 is provided inside the air supply pipe 302. like Figure 7 As shown, the flow interception mechanism 4 includes a mounting rod 401, an upper flow interception plate 404, and a lower flow interception plate 405. The mounting rod 401 is installed on the inner wall of the air supply housing 1. The mounting rod 401 is equipped with a motor 402. The motor 402 is connected to the upper flow interception plate 404 and the lower flow interception plate 405 through a transmission shaft 403. The upper flow interception plate 404 and the lower flow interception plate 405 are provided with air guide holes 406.

[0018] like Figure 4 As shown, the air guide holes 406 of the upper interceptor plate 404 and the lower interceptor plate 405 are offset at a preset angle during installation. When the air guide hole 406 of the lower interceptor plate 405 opens the air outlet of the air supply pipe 302, the air guide hole 406 of the upper interceptor plate 404 moves synchronously to the air inlet of the air supply pipe 302.

[0019] like Figure 5 As shown, the air resistance regulating component 303 includes an adjusting mounting plate 3031, the adjusting mounting plate 3031 having mounting holes 3032 evenly spaced, and the mounting holes 3032 having an air direction adjusting mechanism.

[0020] like Figure 6 As shown, the wind direction adjustment mechanism includes a support frame 3033 disposed in the mounting hole 3032, a mounting sleeve 3034 disposed on the support frame 3033, an adjustment cover 3036 disposed on the outside of the mounting sleeve 3034, a memory alloy spring 3035 disposed inside the mounting sleeve 3034, and a wind speed sensor 3037 disposed on the top of the adjustment cover 3036.

[0021] like Figure 2 As shown, the air mechanism 2 includes a mounting cover 201 and a blower 202. The mounting cover 201 is provided with a through hole for mounting the blower 202, and the blower 202 is located at the through hole.

[0022] Initially, the air guide holes 406 of both the upper and lower throttling plates 404 and 405 coincide with the air supply pipe 302, keeping the air supply pipe 302 open. The motor 402 is connected to the drive shaft 403, and both the upper and lower throttling plates 404 and 405 are mounted on the drive shaft 403. The air guide holes 406 of the upper and lower throttling plates 404 and 405 are offset at a preset angle during installation. When the air guide hole 406 of the lower throttling plate 405 just opens the air outlet of the air supply pipe 302, the air guide hole 406 of the upper throttling plate 404 moves synchronously to the air inlet of the air supply pipe 302, immediately coinciding completely with the air inlet of the air supply pipe 302. Similarly, when the lower throttling plate 405 completely closes the air supply pipe 302... When the air outlet is closed, the air guide hole 406 of the upper baffle plate 404 will simultaneously close the air inlet of the air supply pipe 302.

[0023] Working principle: Reference Figure 1 As shown, the high-efficiency air supply device for biological laboratories provided by this utility model has the following initial state: the air guide holes 406 of the upper interceptor plate 404 and the lower interceptor plate 405 coincide with the air supply pipe 302, keeping the air supply pipe 302 open; the motor 402 is connected to the drive shaft 403, and both the upper interceptor plate 404 and the lower interceptor plate 405 are mounted on the drive shaft 403; the air guide holes 406 of the upper interceptor plate 404 and the lower interceptor plate 405 are offset at a preset angle during installation. When the air guide hole 406 of the lower interceptor plate 405 just opens the air outlet of the air supply pipe 302, the air guide hole 406 of the upper interceptor plate 404 moves synchronously to the air inlet of the air supply pipe 302, and then completely coincides with the air inlet of the air supply pipe 302. Similarly, when the lower interceptor plate 405 completely closes the air supply pipe 302... When the air outlet is closed, the air guide hole 406 of the upper baffle plate 404 will simultaneously close the air inlet of the air supply pipe 302.

[0024] The working process is as follows: After the air supply mechanism 2 is started, the external airflow is drawn into the air supply housing 1 and transported to the external environment through the air supply pipe 302; at the same time, the motor 402 starts, driving the upper interceptor plate 404 and the lower interceptor plate 405 to move synchronously. The next stage enters the critical state one of airflow interception: at this time, the airflow entering the air supply pipe 302 hits the bottom surface of the lower interceptor plate 405, and the kinetic energy and speed are greatly reduced; Next, the sealing section of the upper baffle plate 404 completely seals the upper air inlet of the air supply pipe 302, making the air supply pipe 302 a sealed cavity. Since the airflow inside the cavity has significantly lost kinetic energy and speed, and is in a completely sealed environment, it can quickly settle down, effectively shortening the settling time of the airflow.

[0025] The airflow cutoff release stage then begins: the lower air outlet of the air supply duct 302 opens first. As the upper baffle 404 gradually opens the upper air inlet, the airflow velocity is relatively high as the opening area of ​​the air inlet changes gradually. The wind speed sensor 3037 inside the air supply duct monitors the airflow velocity in real time and adjusts the current of the shape memory alloy spring 3035 based on the detection data. The shape memory alloy spring 3035 changes length through current heating, driving the adjustment cover 3036 to move up and down. When the adjusting cover 3036 moves downward, the flow area between the mounting hole 3032 and the adjusting cover 3036 decreases, the air resistance increases at this point, and the airflow will be diverted to the area with lower air resistance, thereby alleviating the problem of uneven airflow distribution caused by the gradual opening of the air inlet; when the upper baffle 404 fully opens the upper air inlet of the air supply pipe 302, the air supply pipe 302 resumes full air supply, thus completing a complete air supply cycle.

[0026] 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.

[0027] 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.
