Description

Technical Field

[0001] The invention relates to the technical field of fans, and in particular to an energy-saving fan with convenient replacement of filter plates. Background Art

[0002] With the continuous acceleration of urbanization and the increasing industrial pollution, air quality issues have become a focus of increasing concern from all walks of life. Fans play an important role in many fields, and fan filters are an indispensable key component. They can effectively block dust, pollen, bacteria and various harmful substances to improve the air quality of indoor and industrial environments.

[0003] The internal structure of traditional fans is mostly fixed and integrated. When the actual airflow direction does not match the direction of the air inlet and outlet, the air will directly hit the fan components, causing airflow impact disorder. This situation will not only cause greater resistance to air intake, forcing the fan motor to consume more energy to overcome these resistances, thereby affecting the overall operating efficiency of the fan, but also the filter components of traditional fans are often fixed with the help of bolts, nuts and other connectors. This means that when replacing the filter components, tools need to be used to operate multiple connectors. The whole process is cumbersome, complicated and time-consuming. Summary of the invention

[0004] 1. Technical issues to be solved

[0005] In view of the deficiencies in the prior art, the present invention provides an energy-saving fan with convenient replacement of filter plates, which solves the problem of high energy consumption of air intake and air outlet of traditional fans and the problem of inconvenient installation of traditional filter baffles.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] An energy-saving fan for convenient replacement of filter plates, comprising a fan main frame, an air intake assembly is arranged at the front end of the outer wall of the fan main frame, the air intake assembly comprises an air intake mounting wheel, a circle of the inner wall of the air intake mounting wheel is rotatably connected with a plurality of second rotating plates, and the upper and lower parts of the front end of the outer wall of the air intake mounting wheel are both provided with a clamping assembly;

[0009] The clamping assembly includes a clamping rod, and the end of the clamping rod away from the air intake mounting wheel is fixedly connected to a connecting plate, the front end of the inner wall of the air intake mounting wheel is slidably connected to a filter baffle, a circle at both ends of the inner wall of the fan main frame is rotatably connected to multiple first rotating plates, the middle of the front end and rear end of the inner wall of the fan main frame is provided with fixing parts, and the rear end of the fan main frame is provided with a mounting shell.

[0010] Through the above technical solution, when installing the filter baffle, first pull the connecting plate, which will cause the clamping rod to slide on the inner wall of the air intake mounting wheel, and then slide the outer wall of the filter baffle along the inner wall of the air intake mounting wheel. When the pulled connecting plate is released, the return spring connector on the air intake mounting wheel will pull the connecting plate due to the rebound force generated by its own elastic deformation, thereby causing the clamping rod to clamp with the hole on the outer wall of the filter baffle to complete the installation. When replacing the filter baffle, you only need to pull the connecting plate to easily achieve replacement.

[0011] Preferably, the rear end of the outer wall of the connecting plate is fixedly connected with a plurality of return spring connectors, and the ends of the return spring connectors away from the connecting plate are fixedly connected with the outer wall of the air intake mounting wheel;

[0012] Through the above technical solution, when installing the filter baffle, pull the connecting plate and the reset spring connecting piece will be stretched. After the filter baffle is in place, release the connecting plate. The rebound force of the spring can quickly drive the clamping rod to engage with the filter baffle, ensuring the firmness of the installation of the filter baffle and preventing it from being displaced or falling off due to vibration and other factors during the operation of the fan. Compared with complex mechanical fixing methods, this automatic clamping method relying on spring elastic force greatly simplifies the installation process, shortens the time for replacing the filter baffle during fan maintenance, and improves the overall operating efficiency of the equipment.

[0013] Preferably, one end of the clamping rod away from the connecting plate is clamped with the inner wall of the filter baffle;

[0014] Through the above technical solution, the engagement between the clamping rod and the filter baffle can improve the tight fit between the devices.

[0015] Preferably, the front fixing member fixes the outer wall of the air inlet mounting wheel to the inner wall of the fan main frame by bolts, and the rear fixing member fixes the outer wall of the mounting shell to the outer wall of the fan main frame by bolts;

[0016] Through the above technical solution, this front and rear end bolt fixing method limits the key components from two directions, and comprehensively strengthens the connection reliability between the air intake mounting wheel and the fan main frame and between the mounting shell and the fan main frame.

[0017] Preferably, the inner wall of the mounting shell is fixedly connected with a motor, and the output end of the motor passes through the mounting shell to the inside of the fan main frame and is fixedly connected with an impeller;

[0018] Through the above technical solution, the mounting shell provides a stable mounting space for the motor to extend the service life of the motor.

[0019] Preferably, the upper end and the lower end of the inner wall of the air intake mounting wheel are both slidably connected to the clamping rod;

[0020] Through the above technical solution, the sliding design of the clamping rod on the upper and lower ends of the inner wall of the air intake mounting wheel provides a convenient operation path for the installation and removal of the filter baffle. During installation, the operator can easily pull the clamping rod to make enough space for the filter baffle to slide smoothly into the air intake mounting wheel. After the installation is in place, the clamping rod can be quickly reset and locked.

[0021] (III) Beneficial effects

[0022] The present invention provides an energy-saving fan that is convenient for replacing filter plates. It has the following beneficial effects:

[0023] 1. The present invention provides an energy-saving fan that is convenient for replacing filter plates. When the external controller starts the motor, the motor immediately drives the impeller to rotate, thereby generating suction to promote the wind to smoothly enter the fan main frame from the air intake component. In this process, when the wind passes through the air intake mounting wheel, the multiple second rotating plates on the inner wall can rotate flexibly according to the direction of the wind to guide the air into the fan main frame, thereby avoiding the air flow impact and turbulence caused by the air and the components. When the treated air is discharged from the fan main frame, the multiple second rotating plates located at both ends of the inner wall of the fan main frame The first rotating plate begins to rotate with the direction of wind force to guide the outlet air flow. Under the action of the first rotating plate, the outlet air flow can be discharged from the fan outlet in a more uniform and stable state, effectively reducing the eddy current and turbulence at the outlet. Through the coordinated guidance of the airflow by the second rotating plate in the air intake link and the first rotating plate in the air outlet link, the fan achieves an energy saving effect of about 2%-4% in the air intake part and an energy saving effect of about 4%-8% in the air outlet part. This energy-saving effect comprehensively improves the overall energy utilization efficiency of the fan and provides a strong guarantee for the operation of the fan.

[0024] 2. The present invention provides an energy-saving fan that is convenient for replacing filter plates. When installing the filter baffle, first pull the connecting plate, which will cause the clamping rod to slide on the inner wall of the air intake mounting wheel, and then slide the outer wall of the filter baffle along the inner wall of the air intake mounting wheel. When the pulled connecting plate is released, the return spring connecting piece on the air intake mounting wheel will pull the connecting plate due to the rebound force generated by its own elastic deformation, thereby causing the clamping rod to clamp with the hole on the outer wall of the filter baffle to complete the installation. When replacing the filter baffle, it is also only necessary to pull the connecting plate to easily achieve replacement. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0040] like Figure 1-8 As shown, the embodiments of the present invention provide;

[0041] An energy-saving fan for convenient replacement of filter plates, comprising a fan main frame 1, an air intake assembly 3 is arranged at the front end of the outer wall of the fan main frame 1, the air intake assembly 3 comprises an air intake mounting wheel 301, a circle of the inner wall of the air intake mounting wheel 301 is rotatably connected with a plurality of second rotating plates 302, and a clamping assembly 4 is arranged at the upper and lower parts of the front end of the outer wall of the air intake mounting wheel 301;

[0042] The clamping assembly 4 includes a clamping rod 403, and the end of the clamping rod 403 away from the air intake mounting wheel 301 is fixedly connected to the connecting plate 401, the front end of the inner wall of the air intake mounting wheel 301 is slidably connected to the filter baffle 402, and a circle at both ends of the inner wall of the fan main frame 1 is rotatably connected to multiple first rotating plates 101, and the middle of the front and rear ends of the inner wall of the fan main frame 1 are provided with fixing parts 303, and the rear end of the fan main frame 1 is provided with a mounting shell 2.

[0043] After installing the filter baffle 402, pull the connecting plate 401 to make the clamping rod 403 slide against the inner wall of the air intake mounting wheel 301, and then slide the filter baffle 402 along the inner wall of the air intake mounting wheel 301. When the pulled connecting plate 401 is released, the elastic deformation of the return spring connecting piece 404 on the air intake mounting wheel 301 generates a rebound force that pulls the connecting plate 401, thereby making the clamping rod 403 and the filter baffle 402 holes clamped, and the installation is completed. To replace the filter baffle 402, you only need to pull the connecting plate 401 to easily achieve replacement.

[0044] The rear end of the outer wall of the connecting plate 401 is fixedly connected with a plurality of return spring connectors 404, and the ends of the return spring connectors 404 away from the connecting plate 401 are fixedly connected to the outer wall of the air intake mounting wheel 301. When installing the filter baffle 402, the connecting plate 401 is pulled, and the return spring connector 404 is stretched accordingly. After the filter baffle 402 is in place, the connecting plate 401 is released, and the resilience of the spring can quickly drive the clamping rod 403 to engage with the filter baffle 402, thereby ensuring the firmness of the installation of the filter baffle 402 and preventing it from being displaced or falling off due to vibration and other factors during the operation of the fan. Compared with the complex mechanical fixing method, this automatic clamping relying on the spring elastic force greatly simplifies the installation process, shortens the replacement of the filter baffle 402 during fan maintenance, and improves the overall operation efficiency of the equipment.

[0045] The ends of the clamping rods 403 away from the connecting plate 401 are clamped with the inner wall of the filter baffle 402. The clamping rods 403 and the filter baffle 402 are clamped to improve the tight fit between the devices. The front end fixing piece 303 fixes the outer wall of the air intake mounting wheel 301 to the inner wall of the fan main frame 1 through bolts, and the rear end fixing piece 303 fixes the outer wall of the mounting shell 2 to the outer wall of the fan main frame 1 through bolts. This front and rear end bolt fixing method limits the key components from two directions, and comprehensively enhances the connection reliability between the air intake mounting wheel 301 and the fan main frame 1 and between the mounting shell 2 and the fan main frame 1.

[0046] The inner wall of the mounting shell 2 is fixedly connected with a motor 5, and the output end of the motor 5 passes through the mounting shell 2 to the inside of the fan main frame 1 and is fixedly connected with an impeller 6. The mounting shell 2 provides a stable installation space for the motor 5 to extend the service life of the motor 5. The upper and lower ends of the inner wall of the air intake mounting wheel 301 are both slidably connected with the clamping rod 403. The sliding design of the clamping rod 403 on the upper and lower ends of the inner wall of the air intake mounting wheel 301 provides a convenient operation path for the installation and removal of the filter baffle 402. During installation, the operator can easily pull the clamping rod 403 to make enough space for the filter baffle 402 to slide smoothly into the inside of the air intake mounting wheel 301. After the installation is in place, the clamping rod 403 can be quickly reset and locked.

[0047] Working principle: the external controller starts the motor 5, the impeller 6 of the motor 5 rotates, and the rotation of the impeller 6 generates a strong suction force, so that the external air moves toward the fan main frame 1 under the action of the pressure difference, ready to enter the fan. At this time, the air intake component 3 starts to work, the air intake mounting wheel 301 is in the initial state, and the multiple second rotating plates 302 inside it can rotate freely. When the airflow approaches the air intake mounting wheel 301, due to the rotating connection design between the second rotating plate 302 and the air intake mounting wheel 301, the second rotating plate 302 can automatically adjust the angle according to the direction and speed of the airflow;

[0048] If there is a certain angle between the external airflow direction and the axial direction of the air intake mounting wheel 301, the second rotating plate 302 will rotate accordingly, and guide the airflow that may directly impact the inner wall of the air intake mounting wheel 301 to cause turbulence into a smooth airflow along the tangent direction of the inner wall of the air intake mounting wheel 301, effectively reducing the resistance during air intake. This is like a guide plate, avoiding energy loss caused by impact and turbulence, thereby improving air intake efficiency and laying a good foundation for subsequent air processing and transportation.

[0049] When installing the filter baffle 402, the operator pulls the connecting plate 401 to drive the clamping rod 403 to slide on the inner wall of the air intake mounting wheel 301, so that the clamping rod 403 shrinks to a position that does not hinder the installation of the filter baffle 402, and then the outer wall of the filter baffle 402 is aligned with the inner wall of the air intake mounting wheel 301 and slides in. If it is found that the filter baffle 402 is not completely aligned when the connecting plate 401 is loosened, the filter baffle 402 can be rotated for fine adjustment. During the rotation process, when the clamping rod 403 is clamped with the hole on the outer wall of the filter baffle 402, there will be an obvious clamping feeling, indicating that the installation is in place. At this time, the reset spring connector 404 is in a stretched state, applying an inward pulling force to the connecting plate 401 to ensure that the clamping rod 403 is tightly clamped with the filter baffle 402 to prevent the filter baffle 402 from loosening or falling off during operation;

[0050] After the filter baffle 402 is installed, it can effectively prevent impurities in the air from entering the inside of the fan main frame 1, protect the key components such as the impeller 6 inside the fan from being eroded by dust, particles, etc., and extend the service life of the fan. At the same time, the existence of the filter baffle 402 will also have a certain impact on the intake air flow, but due to the rotatable adjustment function of the second rotating plate 302, the intake air flow can quickly return to stability after passing through the filter baffle 402 and continue to flow into the inside of the fan main frame 1;

[0051] The air preliminarily processed by the air intake assembly 3 enters the interior of the fan main frame 1. At this time, the multiple first rotating plates 101 at both ends of the inner wall of the fan main frame 1 begin to interact with the airflow. As the impeller 6 continues to rotate, the air is accelerated and changes its flow direction in the fan main frame 1, forming an airflow with a certain pressure and speed. Under the impact of the airflow, the first rotating plates 101 automatically rotate according to the direction of the airflow. They are like dynamic guide vanes set in the air duct, further arranging and guiding the airflow, so that the airflow is more evenly distributed in the fan main frame 1, reducing the generation of local eddies and turbulence;

[0052] When the filter baffle 402 needs to be replaced, pull the connecting plate 401 again to disengage the clamping rod 403 from the outer wall hole of the filter baffle 402, and then remove the old filter baffle 402 from the air intake mounting wheel 301. If resistance is encountered during the disassembly process, the filter baffle 402 can be properly rotated to make it easier to remove it. When installing a new filter baffle 402, repeat the above installation steps. This convenient replacement method shortens the fan downtime maintenance time, improves the equipment maintenance efficiency, reduces the risk of fan performance degradation due to damage to the filter baffle 402, and ensures that the fan can operate continuously and stably.

[0053] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements that are inherent to such process, method, article or device.

[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
