Description

Filter combination frame

The present invention is related to the filter material frame structure, and particularly refers to a filter mesh binding frame.

Due to the large amount of waste gas emissions in the air in the environment today, there are pollutant particles in the outdoor air. If the human body inhales excessive amounts of pollutants in the air, it can easily cause respiratory diseases. In order to improve the air quality problem, air purifiers are currently on the market, which mainly filter pollutant particles in the air by passing the air through the air filter.

The currently common air filter structure includes a frame and a filter material. The frame has an upper frame and a lower frame. Adhesive is coated between the upper frame and the lower frame, so that the upper frame and the lower frame pass through the adhesive. The glue adheres to each other and is fixed around the filter material.

However, the frame of the conventional air filter has some shortcomings. For example, the frame is processed using this adhesive, which not only increases the cost of the manufacturing process, but also makes it easier to produce glue overflow problems during processing, thereby affecting the quality of the frame. In addition, , this filter material is easy to accumulate air pollution particles after long-term filtration use, and usually needs to be replaced or cleaned regularly. Since the frame is bound to the filter material using adhesive, if you want to replace the filter material alone, you need to use a high-temperature baking method. Only by melting the glue of the frame to reduce the adhesive ability of the glue can the upper frame and the lower frame of the frame be separated and the old filter material removed. However, when reinstalling the new filter material, it is necessary to The frame is re-coated with adhesive, and because of the cumbersome replacement process of the filter material, users will choose to directly discard the old air filter as a whole and reinstall the new air filter. Therefore, it is difficult to recycle the frame when replacing the filter material, resulting in a waste of the cost of the air filter.

In view of this, the purpose of the present invention is to provide a filter binding frame, which not only saves the glue processing cost, but also facilitates the removal and installation of the filter material, and provides the effect of repeated use.

In order to achieve the above object, the present invention provides a filter combination frame for fixing a filter material. The filter combination frame includes a first fixed tooth component and a second fixed tooth component. The first fixed gear has a first datum plane and a first gear row. The first gear row is inclined and disposed on the first datum plane; the second fixed gear is used to communicate with the first fixed gear. To fix the filter material, the second fixed tooth member has a second datum surface and a second tooth row, the second datum surface faces the first datum surface oppositely, and the second tooth row is inclined and arranged on the second datum surface. , wherein the first teeth are against one side of the filter material, and the second teeth are against the other side of the filter material, so that the filter material is clamped between the first clamp and the second between firmware.

The effect of the present invention is that through the design of the filter combination frame of this embodiment, in addition to saving glue processing costs, the inclined design of the first tooth portion of the first clamp and the second tooth portion of the second clamp , to increase the clamping effect of the first teeth and the second teeth against both sides of the filter material, so that the filter material is not easily separated from the first clamp and the second clamp by external force Fixed so that the filter material is stably clamped between the first clamp and the second clamp, and the first clamp and the second clamp are a detachable combination, which is more convenient for disassembly and installation. This filter material provides reusable effects.
