Using the above solution, there are two modes to choose from when smoking.

In the first way, the switching tube 2 is rotated to the first position, and the smoke passage 21 of the switching tube 2 is only connected to one of the filtering channels 11. At this time, the flow rate of smoke during smoking is small.

When the filter component in one of the filter channels is filtered multiple times, the filtering effect will gradually decrease and become invalid. At this time, you can switch to another filter channel to continue using it. With two filter channels, its service life is equivalent to that of an ordinary filter channel. 2 times that of a single-channel filter cigarette holder, greatly extending the service life.

In addition, in this method, the two filter channels 11 can be continuously switched while smoking. First, the smoke passage 21 of the switching tube 2 is connected to the first filter channel. When smoking, cigarette smoke will be sucked into the filter tube 1, and part of the smoke will be directly inhaled by the smoker through the first filter channel. Then, some smoke will enter the second filter channel and be stored in the filter channel. Then rotate the switching tube to connect the smoke passage 21 of the switching tube 2 with the second filter channel. When smoking again, the smoke will be stored in the filter channel. The smoke in the second filter channel will be sucked away, and at the same time, new cigarette smoke will be sucked into the filter tube 1. Part of the smoke will enter the first filter channel and be stored in the filter channel, and then rotate and switch again. The pipe connects the smoke passage 21 of the switching pipe 2 with the first filtering passage, so that the smoking is continuously switched back and forth. In this way, the flue gas can stay in the filter channel for a longer time, and can be more fully adsorbed and filtered by the filter beads, thereby achieving better filtration effect.

In the second way, the switching tube 2 is rotated to the second position, and the smoke passage 21 of the switching tube 2 is connected to the two filtering passages 11 at the same time. At this time, the flow rate of smoke during smoking is larger.

Using the above solution, not only one filter channel can be smoked at a time, but also two filter channels can be smoked at the same time, thereby achieving the purpose of flow adjustment and meeting the needs of different smokers. In addition, by switching between the two filter channels, both Achieve more complete adsorption and filtration purposes, improve filtration performance, and greatly increase the service life of the filter cigarette holder.

It combines blocking filtration and adsorption filtration to achieve multiple filtration effects. Guarantee reliable filtration performance.

Among them, the mechanical filter element 7 and the cigarette connector 6 have an integrated structure, which can further reduce parts and costs.

The filter tube 1 is connected with a switching device for filtering channel selection. The switching device is specifically a switching tube 2. A smoke passage 21 is formed in the switching tube 2. The switching tube 2 can be arranged on the filter. The rear end of the tube 1 is plugged into the filter tube 1. The switching tube 2 can rotate relative to the filter tube 1. By rotating the switching tube 2, the smoke passage 21 and different filter channels 11 can be connected to each other.

The inner wall of the switching tube is also formed with four circumferentially evenly distributed positioning protrusions 4, and the outer wall of the filter tube 1 is correspondingly formed with four positioning grooves 3. There can be a gap between the switching tube 2 and the filter tube 1. Accurate positioning cooperation is achieved through the positioning groove 3 and the positioning protrusion 4, ensuring that when the switching tube 2 and the filter tube 1 rotate relative to each other, the smoke passage 21 can be accurately aligned with one of the filter channels 11.

Furthermore, the mouthpiece 5 is integrally formed with the switching tube 2, and the smoke outlet channel 51 on the mouthpiece 5 is connected with the smoke passing channel 21 of the switching tube 2. Of course, the mouthpiece 5 and the switching tube 2 can also be of separate structure and fixedly connected to each other.

Using the above solution, when the filter component in one of the filter channels is filtered multiple times, the filtering effect will gradually decrease and become invalid. At this time, it can be switched to another filter channel for continued use. With four filter channels, its service life is also It is equivalent to 4 times that of ordinary single-channel filter cigarette holders, which greatly improves the service life.

In addition, during the smoking process, the four filter channels 11 can also be switched sequentially. First, the smoke passage 21 of the switching tube 2 is connected to the first filter channel. When smoking, cigarette smoke will be sucked into the filter tube 1, and part of the smoke will be directly inhaled by the smoker through the first filter channel. Then, some smoke will enter the other three filter channels and be stored in the filter channel. Then rotate the switching tube to connect the smoke passage 21 of the switching tube 2 with the second filter channel. When smoking again, the smoke will be stored in the filter channel. The smoke in the second filter channel will be sucked away, and at the same time, new cigarette smoke will be sucked into the filter tube 1. Part of the smoke will enter the first filter channel and be stored in the filter channel, and then rotate and switch again. The pipe connects the smoke passage 21 of the switching pipe 2 with the third filtering passage, so that the smoke is continuously switched and smoked. In this way, the flue gas can stay in the filter channel for a longer time and can be more fully adsorbed and filtered by the filter beads, thereby achieving better filtration effect.

Using the above solution, through the mutual switching of the four filter channels, it can not only achieve more complete adsorption and filtration purposes, improve the filtration performance, but also greatly increase the service life of the filter cigarette holder.
