Description

Technical Field

[0001] This utility model relates to the field of air filter technology, specifically a high-efficiency air filter guide plate. Background Technology

[0002] An air filter is a device that captures and filters out pollutants such as dust, pollen, PM2.5, odors, and bacteria from the air through internal filters (such as HEPA filters, activated carbon filters, etc.) or purification technologies. It is widely used in homes, offices, automobiles, and industrial settings. Its core function is to improve air cleanliness and provide users with a healthier breathing environment.

[0003] The existing Chinese patent announcement number CN208678622U, entitled "A High-Efficiency Air Filter," explicitly states in its abstract that "This utility model provides a high-efficiency air filter, including a guide pipe, a guide plate, a guide hole, a pre-filter, a medium-efficiency filter, a high-efficiency filter, a fixed frame, and a housing. The guide pipe is fixedly connected to the upper end of the guide plate, the guide plate is fixedly connected to the lower end of the guide plate, and the guide hole is opened at the front end of the guide plate. This design achieves the function of dispersing and guiding the air entering through the inlet hole. The pre-filter, the medium-efficiency filter, and the high-efficiency filter are fixedly connected inside the fixed frame. The fixed frame is fixedly connected to the lower end of the guide plate. This design achieves the function of dispersing and guiding the air entering through the inlet hole. The housing is fixedly connected to the outside of the fixed frame. This design achieves the function of sealing the entire device. This utility model has a novel structure, good filtration performance, is not easily clogged, is easy to assemble and disassemble, and is highly practical."

[0004] However, in this technology, after air enters the filter, it is only dispersed and guided by a fixed diverter and guide pipe. The airflow path cannot be dynamically adjusted, which causes the air to tend to concentrate and pass through specific locations of the filter structure for a long time. This causes local areas of the filter component to accumulate pollutants rapidly due to the continuous high filtration load, resulting in local blockage. This not only shortens the overall service life of the filter component but also reduces the space utilization of the filter component, affecting the long-term stable operation and filtration efficiency of the filter. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency air filter guide plate to solve the problem mentioned in the background art that the airflow is dispersed and guided by only a fixed split plate and guide pipe, which cannot dynamically adjust the airflow path and causes the air to tend to concentrate and pass through a specific position of the filter structure for a long time.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A high-efficiency air filter guide plate includes a housing, and a guide assembly is disposed inside the housing; The flow guiding component includes a rectangular frame, inside which a circular flow guiding plate is disposed. A mounting frame is disposed in front of the rectangular frame, and a rotating plate is rotatably disposed inside the mounting frame. A circular groove is disposed on one side of the rotating plate, and a fan blade is disposed in front of the rotating plate.

[0007] In a preferred embodiment of this utility model, an inlet hole is provided at the front of the housing, and an outlet hole is provided at the rear of the housing.

[0008] In a preferred embodiment of this utility model, both the rectangular frame and the inner side of the mounting frame are circular through-holes.

[0009] In a preferred embodiment of this utility model, the circular guide plate is provided with a guide hole, and the mounting frame is provided with a ball bearing on the side connected to the rotating plate.

[0010] In a preferred embodiment of this utility model, a connecting rod is provided behind the fan blade, and the connecting rod is fixedly connected to the front of the rotating plate.

[0011] In a preferred embodiment of this utility model, a multi-layer filter assembly is provided behind the circular guide plate; the multi-layer filter assembly consists of a first filter screen, a second filter screen, and a third filter screen from front to back.

[0012] In a preferred embodiment of this utility model, the filter opening of the first filter screen is larger than the filter opening of the second filter screen, and the filter opening of the second filter screen is larger than the filter opening of the third filter screen.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0014] Beneficial effects: During air intake, the air passes through the circular slots to the front of the circular guide plate, causing the air to flow backward on one side of the guide plate. The guide holes guide the airflow, and the air is filtered in layers through multiple filter screens. The airflow impact force generated by the airflow acts on the fan blades, causing the fan blades to rotate, which in turn drives the rotating plate to rotate. The position of the circular slots on the rotating plate changes continuously with the rotation, so that the air continuously passes through the guide holes at different positions in front of the circular guide plate. This ensures that the air continuously contacts different positions of the subsequent filter components, preventing the filter components from becoming clogged quickly in local areas due to long-term concentrated filtration, extending the overall service life of the filter components, and improving the space utilization of the filter components.

[0015] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0019] Please refer to Figures 1-4 This utility model discloses a high-efficiency air filter guide plate, including a housing 1. The housing 1 is an installation structure used to install the overall structure. An inlet hole 11 is provided at the front of the housing 1, and an outlet hole 12 is provided at the rear of the housing 1. Air enters the housing 1 through the inlet hole 11, is filtered, and is discharged through the outlet hole 12.

[0020] The housing 1 is equipped with a flow guiding component, which includes a rectangular frame 2. The rectangular frame 2 is a mounting structure used to install other structures. A mounting frame 23 is fixedly connected to the front of the rectangular frame 2. The inner sides of both the rectangular frame 2 and the mounting frame 23 are circular through-holes. A circular flow guiding plate 21 is provided inside the rectangular frame 2. The circular flow guiding plate 21 is provided with a flow guiding hole 22, which guides the air through the flow guiding hole 22, allowing the air to pass through the rectangular frame 2. A rotating plate 24 is rotatably mounted inside the mounting frame 23. A ball bearing 31 is rolled along the connection between the mounting frame 23 and the rotating plate 24, supporting the rotating plate 24 and allowing for smoother rotation. A circular groove 3 is provided on one side of the rotating plate 24. A fan blade 33 is positioned in front of the rotating plate 24, and a connecting rod 32 is positioned behind the fan blade 33. The connecting rod 32 is fixedly connected to the front of the rotating plate 24, thus fixing the fan blade 33 in place. When air is intake, the air passes through the circular groove 3 to the front of the circular guide plate 21, allowing... Air passes backward through one side of the circular guide plate 21. The airflow force generated by the airflow acts on the fan blade 33, causing the fan blade 33 to rotate. This, in turn, drives the rotating plate 24 to rotate, causing the position of the circular groove 3 on the rotating plate 24 to change continuously with the rotation. This allows air to continuously pass through the guide hole 22 at different positions in front of the circular guide plate 21, thus ensuring that the air continuously contacts different positions of the subsequent filter components. This prevents the filter components from becoming rapidly clogged in local areas due to long-term concentrated filtration, extends the overall service life of the filter components, and improves the space utilization of the filter components.

[0021] A multi-layer filter assembly is provided behind the circular guide plate 21. The multi-layer filter assembly consists of a first filter 4, a second filter 41, and a third filter 42 from front to back. The filter opening of the first filter 4 is larger than that of the second filter 41, and the filter opening of the second filter 41 is larger than that of the third filter 42. The multi-layer filter directly adopts the pre-filter, medium-efficiency filter, and high-efficiency filter from the background technology patent for stratified air filtration.

[0022] The working principle of this utility model is as follows: When air is introduced, the air will reach the front of the circular guide plate 21 through the circular groove 3, so that the air passes backward on one side of the circular guide plate 21. The guide hole 22 guides the air. The air is filtered in layers through multiple filter screens. The airflow impact force generated by the air flow acts on the fan blade 33, causing the fan blade 33 to rotate, which in turn drives the rotating plate 24 to rotate. The position of the circular groove 3 on the rotating plate 24 changes continuously with the rotation, so that the air continuously passes through the guide hole 22 at different positions in front of the circular guide plate 21. This allows the air to continuously contact different positions of the subsequent filter components, avoiding rapid blockage of local areas of the filter components due to long-term concentrated filtration, extending the overall service life of the filter components, and improving the space utilization of the filter components.

[0023] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
