Description

TECHNICAL FIELD

[0001] The utility model relates to air purification device technical field, specifically, relate to air purification system's air volume regulating device. BACKGROUND

[0002] As a special place with extremely strict air quality requirements, the sterilization workshop is widely used in pharmaceutical, food processing, medical device manufacturing and other industries. Its production process has very high standards for environmental cleanliness and microbial content. The air purification system plays a key role in the sterilization workshop. It not only effectively filters dust particles, but also strictly controls the number of microorganisms to maintain stable temperature and humidity and air flow organization in the workshop to ensure product quality safety and smooth production process.

[0003] Traditional air purification systems generally use fans with unadjustable wind speed to transport air. Unadjustable wind speed makes it difficult to adjust the purification speed according to actual conditions. Currently, in order to achieve the effect of adjustable air volume, the air inlet of the purification system is usually opened to a suitable size, and a corresponding variable frequency fan is installed for air volume adjustment. The larger the speed of the variable frequency fan, the more air enters through the air inlet, achieving the effect of controlling air volume.

[0004] The utility model patent with the authorization announcement number CN215765631U discloses a food processing workshop air purification and sterilization system, which comprises a wall, a filter screen, a motor, a scraper, an activated carbon filter screen and a U-shaped frame. The wall is internally provided with a ventilation pipe, one end of which is internally provided with a mounting plate. The mounting plate is internally provided with a filter screen. The wall is internally provided with a motor, and the output end of the motor is internally provided with a worm. The wall is internally provided with an exhaust fan. The wall is internally provided with a fixed frame, and the bottom end of the fixed frame is internally provided with a U-shaped frame. The U-shaped frame is internally provided with a rubber pad. The fixed frame is internally provided with a through hole. The fixed frame is internally provided with a door plate. The food processing workshop air purification and sterilization system can drive the pressing plate to move back and forth by deforming the spring, thereby facilitating the installation and disassembly of the activated carbon filter screen.

[0005] Although the technical scheme has the advantage of facilitating the installation and disassembly of the activated carbon filter screen, most air purification systems directly discharge air from the air outlet end of the fan. Since the inner diameter of the air outlet end of the fan is limited, the lack of corresponding flow regulating components will cause the air speed of the air outlet end to be high, which will adversely affect the production workshop. In view of this, we propose an air purification system air volume regulating device. UTILITY MODEL CONTENTS

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Please see Figures 1-4 This utility model provides a technical solution: an air volume adjustment device for an air purification system, including an air purifier body 1. The air inlet of the air purifier body 1 is opened to a suitable size according to the maximum air intake of the variable frequency fan 2. An air inlet hood 21 is fixedly installed at the air outlet of the air purifier body 1. The end of the air inlet hood 21 is connected to the variable frequency fan 2 through an air inlet pipe 20. An air outlet pipe 22 is fixedly installed at the air outlet of the variable frequency fan 2, so that the air purified by the air purifier body 1 can smoothly enter the variable frequency fan 2. By utilizing the adjustable speed of the variable frequency fan 2, flexible control of the air volume is achieved, and the air volume can be adjusted according to actual needs.

[0032] In this embodiment, the end of the air outlet duct 22 is provided with a uniform distribution box 3 for uniformly blowing out airflow. The front side plate of the uniform distribution box 3 is provided with multiple air outlet holes 30. A rigid pipe 31 is fixedly installed at the center of the rear side plate of the uniform distribution box 3. The rear end of the rigid pipe 31 is connected to the air outlet duct 22 through a flexible hose 34. Multiple support rods 32 arranged in a ring at equal intervals are fixedly installed on the front end face of the rigid pipe 31. An air outlet gap 321 is provided between each pair of adjacent support rods 32. A guide plate 33 is fixedly installed at the front end of the multiple support rods 32. The guide plate 33 is located inside the uniform distribution box 3, so that the airflow discharged from the air outlet duct 22 enters the uniform distribution box 3, is dispersed by the air outlet gap 321 between the support rods 32, and then guided by the guide plate 33, is evenly discharged along the air outlet holes 30, thereby achieving uniform distribution of airflow and avoiding excessively high air velocity at the air outlet end from causing adverse effects on the workshop.

[0033] like Figure 2 As shown, a cover frame 211 is fixedly installed on the air intake cover 21. The cover frame 211 is detachably installed on the air outlet housing of the air purifier body 1 by multiple fastening screws, which facilitates fixed installation and disassembly operations.

[0034] like Figure 3 and Figure 4As shown, the guide plate 33 has an arc-shaped guide surface 331 on the side away from the air outlet 30. The cross-section of the arc-shaped guide surface 331 is arc-shaped, which allows the airflow to change direction more smoothly along the arc-shaped guide surface 331 when it flows in the uniform distribution box 3, guiding the air to be evenly discharged along the air outlet 30, further enhancing the effect of uniform airflow distribution, reducing airflow resistance, and making the airflow smoother.

[0035] like Figure 2 As shown, a base plate 11 is fixedly installed on the side of the air purifier body 1. The variable frequency fan 2 and the distribution box 3 are both fixedly installed on the base plate 11, providing a stable installation foundation for the variable frequency fan 2 and the distribution box 3, making the structure of the entire air volume adjustment device more stable and ensuring the stability of the device during operation.

[0036] like Figure 1 As shown, a protective box 10 is fixedly installed on the upper surface of the base plate 11. The protective box 10 protects the variable frequency fan 2 inside, effectively preventing dust, foreign objects and other objects from damaging the variable frequency fan 2, reducing the probability of the variable frequency fan 2 failing due to external factors, extending the service life of the variable frequency fan 2, and also improving the reliability of the device operation.

[0037] In this embodiment, the left and right side plates of the protective box 10 are respectively fixedly installed on the shell of the air purifier body 1 and the distribution box 3. The front side of the protective box 10 is connected to the outside, which can ensure that the structure between the protective box 10, the air purifier body 1 and the distribution box 3 is more robust and stable. The protective box 10 is provided with wiring holes for wiring the variable frequency fan 2, so that wiring operations can be carried out normally.

[0038] Specifically, door panels 12 are hinged to the front sides of the left and right side panels of the protection box 10. A handle 121 is provided on the outer side of the door panel 12, which allows the operator to easily open and close the protection box 10, facilitating the inspection, debugging and other operations of the variable frequency fan 2 inside the protection box 10, and improving the convenience of device maintenance.

[0039] It is worth noting that the rear panel of the protective box 10 is provided with multiple heat dissipation holes 13 that connect to the outside. The bottom wall of the heat dissipation holes 13 is inclined downward at 45°~60°. While ensuring that the heat generated by the variable frequency fan 2 can be discharged smoothly, it effectively prevents dust, rainwater and other foreign objects from entering the protective box 10. This satisfies the heat dissipation needs of the variable frequency fan 2 and ensures the cleanliness of its working environment, thus guaranteeing the normal operation of the variable frequency fan 2.

[0040] Finally, it should be noted that the variable frequency fan 2, the corresponding control switch, the control system, and the external power supply involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0041] When using the air volume adjustment device of the air purification system of this utility model, first determine the appropriate size of the air inlet of the air purifier body 1 according to the air volume of the highest speed of the variable frequency fan 2 and complete the installation. Then, install the air inlet cover 21 at the air outlet of the air purifier body 1 through the cover frame 211 and fastening screws, so that the air inlet cover 21 is firmly connected to the air purifier body 1.

[0042] Next, connect the air outlet duct 22 to the rigid pipe 31 of the distribution box 3 using a flexible hose 34. After turning on the device, the variable frequency fan 2 works, creating negative pressure inside the air purifier body 1. Outside air can be drawn into the air purifier body 1 for purification. Adjust the speed of the variable frequency fan 2 according to actual needs to flexibly control the air volume. The air after the air volume is adjusted enters the distribution box 3 through the air outlet duct 22. Under the action of the support rod 32 and the guide plate 33 with the arc-shaped guide surface 331, the airflow is evenly dispersed and discharged through the air outlet 30.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
