Description

Air filter fan

This creation relates to an air filter fan, mainly a fan that can filter air and easily replace the filter.

Air is the basic demand for people's living. The daily intake of air per person is generally more than 10,000 liters. Therefore, air quality will directly affect human health. However, in industrial modern environment, waste gas generated from coal-fired power generation, industrial waste gas, Many exhaust sources such as steam locomotive exhaust gas, incinerator exhaust gas, etc. cause a lot of air pollution, and generate a large number of tiny aerosols, which cause the suspension particles to be inhaled by the human body and obviously harm the lungs and cardiovascular functions.

In order to improve the above situation, although the mask can be used to filter the air, but the mask will cause discomfort and speech, and the inconvenience of eating is lacking. At present, there are various air filter devices, and the air filter device has a casing, and the casing is inside the casing. The filter screen has a metal outer frame, and a mesh body is arranged in the outer frame, so that when the air enters the filter net, the suspended particles can be filtered by the filter screen to discharge the clean air, and the filter mesh is used for a period of time. After that, you must open the case and remove the filter to replace it, and prevent the air filter from being dirty due to dirty screen.

However, the foregoing structure must disassemble the casing to replace the filter screen, and the replacement is inconvenient, and the filter itself has a metal outer frame and a net body, and the cost is high, resulting in an increase in the use cost.

The present invention includes a fan body and a filter. The fan body has a casing. The casing has a fan net in front of the casing, a fan blade and a motor are disposed in the casing, and a venting portion is disposed behind the casing. The filter device joint portion can be assembled. It is provided at the position or disassembly of the fan main body permeable portion, and the filter is provided with a filter portion, and the outside air is filtered through the filter and then led out by the fan body.

Further, the outer casing of the fan body is provided with an engaging edge corresponding to the inner wall of the peripheral portion of the hollow portion; and the outer edge of the front end of the filter joint portion is slightly smaller than the diameter of the joint edge of the fan body casing, and the front end of the joint portion can be embedded in the hollow portion of the outer casing. And the outer edge of the joint is engaged with the joint edge.

Further, the vacant portion of the rear of the fan main body of the present invention is provided with a plug portion, and the joint portion of the filter can be plugged and combined with the plug portion.

The joint portion of the filter may be made of paper or sponge, and the filter portion of the filter may be made of paper or sponge, and the joint portion and the filter portion of the filter may be made of the same material.

The filter of the present invention can be assembled and disassembled conveniently, and the joint portion and the filter portion of the creation filter can also be integrally formed by the same material, which can reduce the cost effect.

In the following embodiments, the similar functional components of the present invention are represented by the same drawing numbers. Referring to FIGS. 1 to 3, the first embodiment of the present invention includes a fan body 1 and a filter 2, and the fan body 1 has a ring shape. The outer casing 11 has a fan net 12 in front of the outer casing 11, a fan blade 13 and a motor 14 are disposed in the outer casing 11, and a hollow portion 15 is disposed behind the outer casing 11, and the outer casing 11 is provided with an engaging edge 16 corresponding to the inner wall of the peripheral portion of the transparent portion 15.

The filter 2 can be disposed at the position or disassembled of the hollow portion 15 of the fan body 1. The filter 2 has a joint portion 21 which can be made of paper, sponge or other suitable material. The outer edge of the front end of the joint portion 21 is slightly smaller. It is smaller than the diameter of the joint edge 16 of the outer casing 11 of the fan body 1, and the front end of the joint portion 21 can be inserted into the position of the hollow portion 15 of the outer casing 11 and the outer edge of the joint portion 21 is engaged with the joint edge 16, and the joint portion 21 is provided with filtering. In the portion 22, the filter portion 22 is a gas permeable paper, sponge or other suitable material, and the filter portion 22 can be the same material or different material as the joint portion 21.

The filter 2 of the present invention can be directly inserted into the hollow portion 15 of the fan body 1 to combine the joint portion 21 with the joint edge 16 of the outer casing 11, and can be assembled and disassembled for convenience, and can be used when the blade 13 is rotated. The outside air is filtered by the filter unit 22 and then led out by the front fan net 12, and the air flow direction can move the filter 2 toward the fan main body 1 to ensure that the filter 2 does not fall off.

Referring to FIG. 4 and the fifth embodiment of the present invention, the second embodiment is similar to the first embodiment, and the difference is that the fan body 1 is inserted from the top to the bottom of the outer casing 11 . In the portion 17, the joint portion 21 of the filter 2 can be inserted into the plug portion 17, and the filter 2 can be inserted into the plug portion 17 from the joint portion 21 to be engaged with the fan body 1, and can be filtered and easily assembled and replaced. efficacy.

In the creation action, the suspended particles in the air can be adsorbed by the filter 2 to filter the air, and the filter can be easily removed after being used for a period of time, and the replacement can be easily replaced.

In addition, the joint portion 21 and the filter portion 22 of the artificial filter 2 can be integrally formed by using the same material, and the utility model can reduce the use cost.

This creation can be provided at home or in an office or other indoor location. It can filter air to enhance indoor air quality and maintain human health. The filter cost of this creation is low, which can greatly reduce the cost of use and increase the popularity.

Therefore, as described above, the present invention can have better applicability and replace the filter convenience function, and the foregoing embodiment is an example of the creation, and is not a limitation of the creation, and the equivalent change according to the spirit of the creation should also belong to the present invention. Within the scope of creation.
