Description

A deodorizing activated carbon filter

【Technical field】

The utility model relates to a filter for air purification in the field of environmental protection, in particular to a deodorizing activated carbon filter.

【Background technique】

At present, at home and abroad, because the diapers used by babies will be directly thrown into the trash can, and the diapers will emit a very bad smell after a long time, so people have begun to use the excellent adsorption technology of activated carbon. Activated carbon can absorb malodorous components to reduce the concentration of odor in the surrounding area. However, most of the existing activated carbon filters are a sponge loaded with activated carbon. The activated carbon is mixed with adhesive and added to the sponge by spraying or dipping. In this method, the failure of the adhesive is caused by the shedding of the activated carbon, and too much adhesive will reduce the adsorption capacity of the activated carbon and affect the deodorization effect.

In order to solve the above-mentioned existing problems, the utility model makes beneficial improvements.

【Content of utility model】

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a deodorizing activated carbon filter with simple and convenient manufacturing method, low cost, durability, and the ability to quickly and effectively remove odors.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions:

A deodorizing activated carbon filter, including a sponge body, the sponge body sprayed or impregnated with activated carbon for filtering deodorizing gas, characterized in that: the polyurethane sponge body is also coated with a layer of Breathable and anti-leakage material layer;

A deodorizing activated carbon filter as described above is characterized in that: a box with holes on both sides is covered outside the material layer;

A deodorant activated carbon filter as described above, characterized in that: the breathable anti-leakage material layer is polypropylene;

A deodorant activated carbon filter as described above, characterized in that: the material layer is breathable and anti-leakage paper;

A deodorizing activated carbon filter as described above, characterized in that: the shape of the hole of the box is orchid-shaped;

A deodorizing activated carbon filter as described above is characterized in that: the activated carbon is a mixture of activated carbon powder and zeolite powder made of high-quality wood, coconut shells and coal as raw materials.

Compared with the prior art, the utility model has the following advantages: because the utility model is provided with a layer of air-permeable and anti-leakage polypropylene on the original basis, the polypropylene has good air permeability and good anti-leakage effect , so the sponge body wrapped by polypropylene, the activated carbon is distributed in the sponge body, the phenomenon of activated carbon sliding will not appear, so its adsorption capacity will not change, the deodorization ability is strong, and the service life is long; The manufacturing method is simple, convenient and practical, and the price is low.

【Detailed ways】

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

A deodorizing activated carbon filter, comprising a sponge 1, the sponge 1 is sprayed or impregnated with activated carbon 2 for filtering deodorizing gas, the activated carbon 2 is evenly distributed in the sponge 1, and the sponge 1 In a fluffy state, it has the advantages of low airflow resistance and good ventilation performance, and the gas can easily pass through the sponge body 1, so that the activated carbon 2 hidden in the sponge body 1 can fully absorb the odor in the gas, and the deodorization efficiency is high. The polyurethane sponge body 1 is also covered with a layer of breathable and anti-leakage material layer 3. The material layer 3 is polypropylene, which has good air permeability and good anti-leakage effect. , so the sponge body 1 wrapped in polypropylene, the activated carbon will be distributed in the sponge body, when some activated carbon 2 slips, the polypropylene wrapped sponge body 1 can block the activated carbon 2, so that the activated carbon will not fall down .

A box 5 with holes 4 on both sides is covered on the outside of the polypropylene. The box 5 has holes on both sides to realize the entry and exit of gas. The sponge body 1 is put into the box for supporting and convenient use. When replacing, take out the whole box, and then replace it with a new one to use it. The shape of the hole 4 of the box 5 is orchid-shaped, which is in order to increase the aesthetics of the entire filter port and ensure the best adsorption effect. The shape of the hole 4 of the box 5 can also be other shapes, such as Square, circle, polygon, etc.
