Problems solved by technology

However, the cigarette filter in this patent application mentions that the depth of the groove is 0.5-2 mm, so combined with laser drilling technology, all the smoke will be concentrated near the ventilation holes, which will cause a large amount of smoke loss. This combination will not achieve the invention. The expected effect of the user will cause a strong sense of emptiness, and consumers will not be able to taste the aroma of tobacco through this type of design

Embodiment 1

[0045] A polystyrene smoke filter device with a diameter of 6 mm and a length of 20 mm was manufactured by an injection molding process. The appearance is cylindrical, and the interior has 6 microchannels evenly distributed, and its cross-sectional shape is circular. The inner diameter of the first 10 mm section of the micro-channel is 0.2 mm, and the inner diameter of the last 10 mm section is 0.4 mm. Among the 6 flow channels, the small inner diameter sections of 3 flow channels face upwards, and the large inner diameter sections of the other 3 flow channels face upwards, which are evenly distributed to ensure that the smoke filter device has a front-to-back symmetrical structure.

Embodiment 2

[0047] A polybutylene succinate smoke filter device with a diameter of 10 mm and a length of 5 mm was manufactured by an injection molding process. The appearance is cylindrical, and the inside has 8 micro-channels evenly distributed, and its cross-sectional shape is a circle with a diameter of 1 mm. The middle of the microchannel has a bend.

Embodiment 3

[0049] A styrene-acrylonitrile copolymer flue gas filter device with a diameter of 4 mm and a length of 25 mm was manufactured by an injection molding process. It is cylindrical in appearance, with recesses 8 with a height of 3 mm at its upper and lower ends, and a plurality of micro-flow channels evenly distributed inside, and its cross-sectional shape is circular. Uniform distribution ensures that the flue gas filter has a front-to-back symmetrical structure.

[0050] As a variant, it is also possible to use Figure 4 In the flow channel structure shown, the front end of the micro-channel is a square with a side length of 0.2 mm, and the end is a square with a side length of 0.3 mm, and its longitudinal cross-sectional shape is trapezoidal. A total of 8 flow channels are constructed, of which 4 flow channels have small inner diameter ends facing upwards, and the other 4 flow channels have large inner diameter ends facing upwards, so as to ensure that the filter device has a...

Abstract

The invention relates to a flue gas filtering device of one-time injection molding, which comprises a column body, the micro flow channel for common flue gas flow is arranged in the column body, and the inside of the column body has a front-rear symmetrical structure. Through the unique micropore design of the present invention, the flow velocity of the flue gas is increased, the flow state of the flue gas is changed, and a part of harmful substances such as tar is settled and adsorbed.

Description

【Technical field】 [0001] The invention relates to a flue gas filtering device. More specifically, the present invention relates to a one-time injection molding smoke filter device. 【Background technique】 [0002] With the progress of society, the issue of "smoking and health" has aroused widespread social concern. With the continuous improvement of living standards, people's health awareness is getting stronger and stronger. "Smoking and health" has become one of the main challenges faced by the tobacco industry during its development. [0003] When cigarettes are burned, the mainstream smoke contains harmful substances such as CO, HCN, NNK, ammonia, benzo-α-pyrene, phenol, crotonaldehyde, tar, and nicotine. In order to reduce the harm caused by smoking tobacco products, practitioners in the tobacco industry use various filtering equipment, such as ordinary acrylic fiber filters, acetate fiber filters, composite filter rods, etc. Cigarette filter rods are used as filter ...
