Description

A cigarette holder with radially layered air passage

technical field

The invention relates to the technical field of electronic cigarettes, in particular to a mouthpiece with radially layered air passages.

Background technique

Different from the continuous burning of traditional cigarettes, the heater of the electronic cigarette is a heating process for each smoking process of the electronic cigarette liquid according to the length of time of smoking the electronic cigarette during each smoking process of the smoker. . The heating process is a process from relatively low temperature to high temperature, and then back to relatively low temperature. In this process, due to the different operating temperature of the heater, the e-liquid with multiple components will evaporate components and spices with different boiling points at different stages of smoking the same smoke, so the evaporated smoke needs to be Enter a device that can well mix the components of the smoke that have been volatilized in different stages during the same puff. However, the ends of the existing electronic cigarettes are all directly sucked from the atomizer. The suction end is a straight-through channel or a small section of smoke filter cotton and other components are added. However, the length of such components is very small, only a few millimeters, and the diameter of the hole It is only 0.3~3 mm, so the function and effect on the mixing of atomized smoke is very limited. On the other hand, the particle size of e-cigarette smoke is only about one-tenth of the particle size of the smoke formed by burning traditional cigarettes, so smokers often feel that the fullness of e-cigarette smoke is not enough after entering the mouth.

Compared with prior art, the present invention has following advantage:

(1) By increasing the internal structure of the cigarette holder, the present invention makes the smoke that needs to be mixed pass through cavities with different volumes and different spaces through different space partitions or re-divisions while maintaining a similar diameter to the original suction nozzle. When the smoke volatilized at different times passes through a longer space and cavity, the smoke is further mixed, so that consumers can obtain a better smoking experience. On the other hand, the smoke is transmitted through a relatively longer channel, and the high-temperature e-cigarette smoke is further cooled, so that the e-cigarette smoke gradually condenses from a tiny mist into a larger particle shape, which overcomes the impact of e-cigarette smoke on the oral cavity. The impact has the disadvantage of insufficient fullness, which solves the problem of insufficient fullness of electronic cigarette smoke, and effectively improves the overall sensory quality of electronic cigarettes.

(2) The design of the present invention is scientific and reasonable, and it is easier to manufacture and assemble, the interchangeability of components is good, and the manufacturing cost is lower.

Cigarette sticks. When it is used to smoke ordinary cigarettes, because the particle size of the smoke generated when the cigarette is burned is relatively large, when using this cigarette holder to smoke, there is also a composite airway passing through the cigarette holder, which will cause the smoke to cool down And the characteristics of making the particle size larger, when the smoke further passes through the composite air channel, some harmful components in the smoke with large molecular weight or enlarged molecules will stay or be trapped in the tube wall of the cigarette holder, which is very important for reducing the smoke of traditional cigarettes. Harmful components such as tar in the air can greatly contribute to improving the aroma of tobacco; therefore, the present invention can not only be used in e-cigarettes to improve the fullness of smoke and improve the taste of smoking, but also can be used to reduce the smoke when smoking traditional cigarettes. A new type of tool for harmful ingredients has a good market prospect.

When in use, when smoking, the smoke from the main body of the electronic cigarette enters from the ventilation duct of the connecting part 1, enters the first airflow channel from the end air intake hole of the end air intake seat 3, and then passes through the first air intake seat 11, the axial air inlet and the radial air inlet enter the second airflow channel, and then enter the air duct of the second circular pipe 7 through the radial air hole and the axial air hole of the second air intake seat 4, and then from The air outlet 13 of the sealing plug 12 flows out, and finally reaches the mouth of the smoker. After the smoke flows through the various components, the temperature of the smoke has dropped significantly. During the process of dropping the temperature of the smoke, the particle size of the smoke molecules also decreases. With the temperature drop and the long-distance circulation and mixing, the particle size also increases, which can significantly improve the fullness of the e-cigarette smoke.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
