Description

Technical Field

[0001] This utility model relates to the field of liquid tank air outlet technology, and more specifically, to a pressurized liquid tank air outlet with a built-in fan. Background Technology

[0002] In fields with stringent requirements for air cleanliness, such as electronic semiconductor manufacturing, biopharmaceuticals, hospital operating rooms, and precision instrument laboratories, cleanrooms serve as the core production and operating environment. The performance of their terminal air purification equipment directly determines the cleanliness level of the room. As a key component of the cleanroom's terminal purification system, the liquid tank air outlet's main function is to deeply filter the air entering the room through its built-in high-efficiency filter. At the same time, it relies on the liquid tank's sealing structure to prevent the leakage of contaminated air, ultimately providing a stable clean airflow to the room to meet the needs of high-precision production and aseptic operation.

[0003] A search revealed that Chinese patent CN216769685U discloses a high-efficiency air inlet for liquid tanks. This structure achieves flexible adjustment of the air inlet diameter by inserting a baffle inside the air inlet, along with a pull-out adjustment rod and a locking bolt. This solves the problems of inconvenient airflow adjustment, complex structure, and high production cost of traditional liquid tank air inlets, and has certain improvement significance in terms of airflow control convenience and cost optimization.

[0004] However, in actual use, existing liquid tank air outlets mainly use passive air intake when air is introduced into the air inlet, which makes it difficult to pressurize the external air. This results in slow airflow, slow diffusion, and uneven coverage, leading to low filtration accuracy and difficulty in meeting the needs of high-cleanliness scenarios. In view of this, this utility model proposes a liquid tank air outlet with built-in fan pressurization. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pressurized liquid tank air outlet with a built-in fan to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a liquid tank air outlet with built-in fan pressurization, including a liquid tank air outlet body with a detachable high-efficiency filter, an air inlet at one end of the liquid tank air outlet body and an air outlet at the other end, and a fan pressurization structure inside the air inlet.

[0007] Preferably, the fan pressurization structure includes a support plate, which is fixedly supported inside the air inlet. A through hole is formed on the surface of the support plate, and a support frame is fixedly installed inside the through hole. A bearing is fixedly embedded in the center of the surface of the support frame, and a shaft is installed inside the bearing. The support plate has a rectangular structure, and its outer wall is attached to the inner wall of the air inlet. The shaft is rotatably connected to the support frame through the bearing. A drive assembly is provided at one end of the shaft, and a detachable fan blade assembly is installed on the outside of the shaft.

[0008] Preferably, the drive assembly includes a motor, which is fixedly mounted on the inner wall of the support plate away from the through hole, and a first transmission wheel is fixedly mounted on the output end of the motor. A second transmission wheel is fixedly mounted on one end of the shaft, and a transmission belt is mounted on both the first and second transmission wheels.

[0009] Preferably, the detachable fan blade assembly includes a hexagonal column, which is fixedly installed at the other end of the shaft. A mounting ring is inserted into the hexagonal column, and the mounting ring has a insertion hole adapted to the structure of the hexagonal column. The mounting ring is slidably inserted into the hexagonal column through the insertion hole. Several fan blades are distributed in a ring on the mounting ring. One end of the hexagonal column has an internal threaded hole, and a limit screw is installed in the internal thread of the internal threaded hole.

[0010] Preferably, a diffuser is provided at the air outlet, and the diffuser is detachably connected to the air outlet by screws.

[0011] The technical effects and advantages of this utility model are as follows: By setting up a fan pressurization structure, the motor in the drive assembly drives the first transmission wheel to rotate, which in turn drives the second transmission wheel and shaft via a transmission belt. This causes the detachable fan blade assembly to rotate at high speed with the shaft, forming a directional pressurized airflow. This effectively increases the flow rate and pressure of external air entering the liquid tank air inlet body, prompting the air to quickly pass through the support plate holes and flow through the high-efficiency filter. This shortens the air filtration response time and ensures the output of filtered clean air per unit time, significantly improving the device's purification efficiency for ambient air. By setting up a detachable fan blade assembly, and utilizing the interlocking fit between the hexagonal post and the mounting ring, as well as the fastening of the limiting screw, the fan blades can be quickly disassembled for cleaning, preventing dust accumulation on the blades from affecting the pressurization performance, reducing the maintenance difficulty of the device, and extending the overall service life. At the same time, when the motor in the drive assembly drives the shaft to rotate through the first transmission wheel, the second transmission wheel, and the transmission belt, the motor is fixedly installed on the inner wall of the support plate and away from the through hole, and the outer wall of the support plate is attached to the inner wall of the air inlet. Therefore, due to the obstruction of the support plate, air can enter through the through hole on the support plate, and the motor is less affected by dust in the air. Attached Figure Description

[0018] 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.

[0019] As attached Figure 1-5 The liquid tank air outlet shown includes a liquid tank air outlet body 1 with a detachable high-efficiency filter. One end of the liquid tank air outlet body 1 is provided with an air inlet 2 and the other end is provided with an air outlet. The air inlet 2 is provided with a fan pressurization structure inside.

[0020] Specifically, in this structure, the fan pressurization structure enables external air to be pressurized and quickly enter the interior of the liquid tank air outlet body 1 through the air inlet 2. After being filtered by the high-efficiency filter inside the liquid tank air outlet body 1, it is discharged through the air outlet. The high-efficiency filter can be installed inside the liquid tank vent body 1, which is existing technology and will not be described here.

[0021] The above structure will be explained in detail below: In this embodiment, as shown in the appendix Figure 1 , 3As shown in Figure 4, the fan pressurization structure includes a support plate 3, which is fixedly supported inside the air inlet 2. A through hole 4 is opened through the surface of the support plate 3, and a support frame 5 is fixedly installed inside the through hole 4. A bearing 6 is fixedly embedded in the center of the surface of the support frame 5, and a shaft 7 is installed inside the bearing 6. The support plate 3 has a rectangular structure, and the outer wall of the support plate 3 is attached to the inner wall of the air inlet 2. The shaft 7 is rotatably connected to the support frame 5 through the bearing 6. A drive assembly is provided at one end of the shaft 7, and a detachable fan blade assembly is installed on the outside of the shaft 7.

[0022] Specifically, in this structure, when external air enters the interior of the liquid tank air outlet body 1 through the air inlet 2, the drive component first drives the shaft 7 to rotate at the support frame 5 through the bearing 6. The shaft 7 drives the detachable fan blade assembly to rotate, accelerating the flow of external air and allowing the air to quickly enter the interior of the liquid tank air outlet body 1. The surface of the support plate 3 has through holes 4, and a support frame 5 is installed at the through holes 4. Therefore, the flowing air can enter the interior of the liquid tank air outlet body 1 through the through holes 4 at the support plate 3 without affecting the air flow.

[0023] In this embodiment, as shown in the appendix Figure 3 , 4 As shown, the drive assembly includes a motor 8, which is fixedly installed on the inner wall of the support plate 3 away from the through hole 4. A first transmission wheel 9 is fixedly installed at the output end of the motor 8, and a second transmission wheel 10 is fixedly installed at one end of the shaft 7. A transmission belt 11 is installed on both the first transmission wheel 9 and the second transmission wheel 10.

[0024] Specifically, in this structure, when the shaft 7 is driven to rotate by the drive assembly, the motor 8 can drive the first transmission wheel 9 to rotate, and under the action of the transmission belt 11, the second transmission wheel 10 can drive the shaft 7 to rotate. It should be noted that the contact surfaces of the first transmission wheel 9, the second transmission wheel 10, and the transmission belt 11 are all provided with anti-slip serrated structures and have good tension. Therefore, the first transmission wheel 9, the second transmission wheel 10, and the transmission belt 11 will not slip or fall off during the transmission process. In addition, the motor 8 is fixedly installed on the inner wall of the support plate 3 and away from the through hole 4, and the outer wall of the support plate 3 is attached to the inner wall of the air inlet 2. Therefore, due to the obstruction of the support plate 3, air can enter through the through hole 4 on the support plate 3, reducing the influence of dust in the air on the motor 8.

[0025] In this embodiment, as shown in the appendix Figure 5As shown, the detachable fan blade assembly includes a hexagonal post 12, which is fixedly installed on the other end of the shaft 7. A mounting ring 13 is inserted into the hexagonal post 12, and the mounting ring 13 has a insertion hole 14 that is adapted to the structure of the hexagonal post 12. The mounting ring 13 can be slidably inserted into the hexagonal post 12 through the insertion hole 14. Several fan blades 15 are distributed in a ring on the mounting ring 13. One end of the hexagonal post 12 has an internal threaded hole 16, and a limit screw 17 is installed in the internal thread of the internal threaded hole 16.

[0026] Specifically, in this structure, when the shaft 7 rotates, it can drive the hexagonal column 12 to rotate. Since the mounting ring 13 has a plug hole 14 that is compatible with the structure of the hexagonal column 12, and the mounting ring 13 can be slidably plugged into the hexagonal column 12 through the plug hole 14, the hexagonal column 12 can drive the mounting ring 13 to rotate, which in turn drives the fan blade 15 to rotate, so as to achieve the purpose of pressurizing and flowing the external air. When the fan blade 15 needs to be disassembled and cleaned, unscrew the limiting screw 17 from the internal threaded hole 16. At this time, the mounting ring 13 loses its limiting position at the limiting screw 17. Slide the mounting ring 13 from the hexagonal post 12 to remove it, and then the fan blade 15 can be disassembled and replaced. Similarly, when installing the fan blade 15, the mounting ring 13 is inserted into the hexagonal post 12 through the insertion hole 14, and the limiting screw 17 is screwed into the internal thread hole 16 to limit and tighten the mounting ring 13, thus completing the installation operation of the fan blade 15.

[0027] In this embodiment, as shown in the appendix Figure 2 As shown, a diffuser 18 is provided at the air outlet, and the diffuser 18 is detachably connected to the air outlet by screws.

[0028] Specifically, the structure mounts the diffuser 18 at the air outlet with screws, which can be easily disassembled and facilitates air exhaust.

[0029] Working principle of this utility model: This application provides a self-contained fan pressurized liquid tank air outlet. In actual use, the drive component of the device is first started, and the motor 8 starts to run. The output end of the motor 8 drives the fixed first transmission wheel 9 to rotate. Since the contact surface of the first transmission wheel 9, the transmission belt 11, and the second transmission wheel 10 is provided with an anti-slip sawtooth structure and has good tension, the transmission belt 11 will stably drive the second transmission wheel 10 to rotate synchronously. The second transmission wheel 10 is fixed to one end of the shaft 7, and finally drives the shaft 7 to rotate stably through the bearing 6 of the support frame 5 on the support plate 3. When shaft 7 rotates, the hexagonal column 12 fixed at its other end will rotate synchronously. Since the mounting ring 13 is slidably inserted into the hexagonal column 12 through the matching insertion hole 14, the hexagonal column 12 will drive the mounting ring 13 and the fan blade 15 on the mounting ring 13 to rotate together. The high-speed rotation of the fan blade 15 generates negative pressure and thrust, forming a pressurization effect, providing a power basis for the rapid entry of external air into the device. Under the pressurization of the fan blade assembly, external air is quickly drawn in and enters from the air inlet 2 of the device. Since the support plate 3 is fixed inside the air inlet 2 and the surface of the support plate 3 has through holes 4, the air will directly pass through the through holes 4 and enter the liquid tank air inlet body 1. At the same time, the support plate 3 can block some dust from contacting the motor 8, reducing the contamination of the motor 8. Air entering the liquid tank air outlet body 1 will first flow through the high-efficiency filter pre-installed inside the liquid tank air outlet body 1. The air is purified and filtered of impurities, particles and other pollutants inside the high-efficiency filter to ensure that the air discharged afterwards meets the cleanliness requirements. The clean air after purification and filtration will continue to flow to the air outlet of the device. The diffuser 18 at the air outlet can guide the air to be discharged smoothly and evenly.
