Technical Field

[0001] The invention relates to a smoking article, in particular to a water mist filtering smoking article. Background Art

[0002] In recent years, as people pay more and more attention to health, they have realized that traditional cigarettes have certain harm to health. The impact of traditional cigarettes on health and the environment has gradually begun to receive attention from countries around the world.

[0003] It has become a consensus at home and abroad that smoking is harmful to health. Since tar and other harmful components in cigarette smoke are water-soluble to a certain extent, water can be used as a filtering medium to achieve the purpose of reducing tar and reducing harm. Currently, there are various types of hookah smoking utensils on the market, which use liquid water to filter cigarette smoke. That is, when smoking a cigarette, the smoke first passes through water and then is inhaled by the human body. This smoking method allows many harmful components in the smoke to be filtered by liquid to reduce harm to the human body.

[0004] However, in this type of smoking device, the smoke is in the form of bubbles when passing through water. Only the harmful components in the smoke on the surface of the bubbles are absorbed by the water, and a large amount of gas inside the bubbles does not contact the water, so the adsorption effect is not sufficient.

[0005] Therefore, how to provide a smoking device with sufficient filtration, tar reduction and harm reduction effect has become a technical problem to be solved urgently in this field. Summary of the invention

[0006] The technical problem to be solved by the present invention is a smoking device with sufficient filtering, good tar reduction and harm reduction effects.

In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0049] It should be noted that in this specification, similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0050] In the description of this embodiment, it should be noted that the terms "upper", "lower", "inner", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the inventive product is usually placed when used. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0051] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0052] like Figure 1-4 As shown, the present invention provides a water mist filtering smoking device, comprising a housing and a water mist generating device, wherein:

[0053] The shell is provided with a smoke outlet 13 and a smoke inlet 11, and a mixing chamber 21 is provided inside the shell. The mixing chamber 21 is communicated with the smoke outlet 13 and the smoke inlet 11, and the smoke enters the mixing chamber 21 from the smoke inlet 11;

[0054] The water mist generating device is in communication with the mixing chamber 21 . The water mist and smoke generated by the water mist generating device are mixed in the mixing chamber 21 and then flow out through the smoke outlet 13 .

[0055] Furthermore, the flue gas described in the present invention refers to volatile compounds containing nicotine generated by tobacco materials and their processed products, and can be new tobacco products, such as the flue gas generated by electronic cigarettes or heat-not-burn smoking devices; it can also be the flue gas generated after traditional tobacco such as cigarettes or pipes are ignited.

[0056] When the smoker inhales, the unfiltered smoke enters the mixing chamber 21 through the smoke inlet 11 and mixes with the water mist generated by the water mist generating device. Since the water mist particles are fine, the smoke and water mist mix with each other, and the contact area is much larger than that of the bubbles of smoke in water. In the same period of time, the water mist and smoke mix more fully, and the contact area is greatly increased, which is beneficial to improving the effect of reducing tar and reducing harm. In addition, the amount of water used is greatly reduced, making it convenient to carry and use.

[0057] Furthermore, since harmful substances in the smoke are dissolved in the water mist and condensed on the inner wall of the mixing chamber 21, it needs to be cleaned from time to time. Therefore, in the present invention, the housing is configured as an upper housing 10 and a lower housing 20, and the upper housing 10 and the lower housing 20 are detachably connected. When cleaning is required, the upper housing 10 and the lower housing 20 are disassembled to clean the mixing chamber 21 inside the housing.

[0058] Furthermore, the smoke outlet 13 and the smoke inlet 11 can be arranged on the upper shell 10. The upper shell 10 and the lower shell 20 together enclose the mixing chamber 21. The lower shell 20 is used for the smoker to hold, so that the smoker can hold the smoking utensil conveniently.

[0059] Furthermore, if Figure 1-4 As shown, the smoking device of the present invention also has a specially matched cigarette insertion assembly 15, which is convenient for smokers to smoke cigarettes. The cigarette insertion assembly 15 can be detachably inserted into the smoke inlet 11, and the cigarette insertion assembly 15 includes a cigarette socket 16 and an air inlet channel 17. The cigarette socket 16 is used to accommodate cigarettes 30. Since the smoke inlet 11 and the smoke outlet 13 are both arranged on the upper shell 10, the air inlet channel 17 needs to extend in a direction away from the smoke outlet 13, that is, to the direction of the lower shell 20. The air inlet channel 17 is used to guide the smoke generated by the cigarette 30 into the mixing chamber 21 to prevent the smoke from being sucked out from the smoke outlet 13 without being filtered once the smoke enters the shell.

[0060] Furthermore, if Figure 1 As shown, in a preferred embodiment of the present invention, the smoke outlet 13 can be directly disposed on the upper shell 10 and formed integrally with the upper shell 10 .

[0061] Furthermore, after the smoke and water mist are mixed, a mixture of smoke and water mist may exist at the smoke outlet 13, and part of the water mist may be inhaled by the human body before it has time to condense, thereby reducing the taste of the smoke. Therefore, a device for separating water mist and smoke can be added near the smoke outlet 13. By utilizing the fact that the specific gravity of water mist is greater than that of smoke, the path for the smoke to flow is increased, and the water mist and smoke are separated by the principle of collision or rotational centrifugation, so that basically only smoke is inhaled in the end.

[0062] In a preferred embodiment of the present invention, Figure 2 As shown, one end of the mixing chamber 21 connected to the smoke outlet 13 is an outlet channel 14, and a blocking member 12 is provided in the outlet channel 14, and the blocking member 12 is used to extend the path of smoke flow in the outlet channel 14. By extending the smoke flow path, the amount of water mist sucked out from the smoke outlet 13 can be effectively reduced.

[0063] Furthermore, the structure of the blocking member 12 is not particularly limited, as long as it can achieve the function of increasing the smoke flow path. Figure 2 Baffles on opposite sides of the inner wall of the air outlet passage 14 are alternately arranged.

[0064] Furthermore, the air outlet channel 14 may be spiral-shaped, and the water mist and smoke may be separated by the principle of rotational centrifugation.

[0065] In addition, in another preferred embodiment of the present invention, an obstruction may be provided in the air outlet channel 14, and an air hole is provided on the obstruction, and smoke can only reach the smoke outlet 13 through the air hole. By reducing the cross-sectional area of ​​the smoke channel, the water mist content in the smoke can also be reduced, thereby improving the taste of the smoke.

[0066] Alternatively, if Figure 4 As shown, a first obstruction 141 may be provided in the smoke passage 14, and an air hole 142 may be provided on the first obstruction 141, and the number of the air holes may be one or more; further, a plurality of obstructions may be provided in the smoke passage 14 as required.

[0067] Alternatively, if Figure 3 and Figure 4 As shown, the water mist filtering smoking device provided by the present invention also includes a suction nozzle 18, which is detachably connected to the shell, and the smoke outlet 13 is arranged on the suction nozzle 18, and the aforementioned air outlet channel 14 is formed in the suction nozzle 18; it can be understood that the air outlet channel in the suction nozzle 18 can also be provided with the aforementioned blocking member and / or obstruction portion.

[0068] Furthermore, the water mist generating device includes an atomizing component 25 and a water storage chamber 23 . The atomizing component 25 is used to atomize water in the water storage chamber 23 to generate water mist. The atomizing component 25 is connected to the mixing chamber 21 .

[0069] Furthermore, there is no special limitation on the location of the water mist generating device, as long as it can guide the generated water mist into the mixing chamber, and it can be set inside the housing or outside the housing, and can be integrally formed with the housing or detachably connected to the housing.

[0070] In a preferred embodiment of the present invention, Figure 1 As shown, the water storage chamber 23 and the atomizing assembly 25 can be arranged in the housing, and a partition plate 22 is arranged in the lower housing 20. The inner cavity of the lower housing 20 is divided into a mixing chamber 21 located at the upper part and a water storage chamber 23 located at the lower part by the partition plate 22. The atomizing assembly 25 is arranged on the partition plate 22, and generates water mist in the mixing chamber 21 after absorbing water from the water storage chamber 23. The sewage generated after the water mist in the mixing chamber 21 is condensed is stored in the mixing chamber 21 and does not flow into the water storage chamber 23.

[0071] Further, the water storage chamber 23 is provided with a water injection port communicated with the outside of the housing, and the water injection port is sealed with a sealing cover 24. When the water in the water storage chamber 23 is exhausted, the sealing cover 24 can be opened to conveniently inject water into the water storage chamber 23.

[0072] Alternatively, in another preferred embodiment of the present invention, Figure 3 As shown, the water storage chamber 23 is arranged outside the housing and is detachably connected to the atomizing assembly 25. The atomizing assembly 25 is also arranged on the upper housing 10. The water stored in the water storage chamber 23 continuously flows into the atomizing assembly 25 under the action of gravity and is atomized into water mist. The generated water mist is mixed with the smoke in the mixing chamber 21 and then sucked out from the smoke outlet 13. When the water in the water storage chamber 23 is exhausted, the water storage chamber 23 can be removed from the atomizing assembly 25, and after the water storage chamber 23 is filled with water, the water storage chamber 23 can be installed on the atomizing assembly 25.

[0073] Alternatively, in another preferred embodiment of the present invention, Figure 4 As shown, the water storage chamber 23 is arranged in the shell and is detachably connected to the atomizing assembly 25. After opening the upper shell 10, the water storage chamber 23 can be easily removed from the atomizing assembly 25. After filling the water storage chamber 23 with water, the water storage chamber 23 is installed on the atomizing assembly 25.

[0074] Furthermore, the atomization component 25 can be implemented by common atomization methods in the art, such as heating, vibration, spraying, etc. In the present invention, the atomization component 25 preferably includes an ultrasonic atomization sheet, which can stably provide water mist, and the temperature of the smoking device will not be too high, and the water mist is easier to condense.

[0075] Furthermore, the water mist filtering smoking device also includes a battery 26 for supplying power to the water mist generating device.

[0076] Furthermore, the smoking device also includes a switch 27 for controlling the opening and closing of the atomization assembly 25 . Specific embodiments

[0078] Example 1

[0079] A well-known domestic brand of cigarettes was selected, and the cigarette smoke generated by filtering the water mist filtering smoking device provided by the present invention was captured according to GB / T 19609-2004 "Determination of total particulate matter and tar in cigarettes using a conventional analytical smoking machine", and the nicotine in the total particulate matter of cigarettes was determined according to GBT 23355-2009 "Gas chromatography method for determination of nicotine".

[0080] Comparative Example 1

[0081] The detection conditions are the same as those in Example 1, except that the detection object is cigarette smoke filtered by a commercially available conventional hookah smoking device.

[0082] Comparative Example 2

[0083] The detection conditions are the same as those in Example 1, except that the detection object is unfiltered cigarette smoke.

[0084] Table 1

[0085] Smoke composition Example 1 Comparative Example 1 Comparative Example 2 Nicotine / mg 0.15 0.34 0.92 Tar / mg 3.38 7.67 11.61 Water / mg 5.14 0.5 0.47

[0086] The smoke components in Example 1 and Comparative Examples 1-2 are shown in Table 1. In Comparative Example 2, under normal smoking conditions, the tar content of the unfiltered cigarette smoke is 11.61 mg / cigarette, but after filtering using the smoking device provided by the present invention, the tar content is reduced to 3.38 mg / cigarette, a decrease of 70.9%, and the tar reduction effect is obvious.

[0087] In Comparative Example 1, the filtering effect of the traditional hookah is a 63.0% reduction in nicotine and a 33.9% reduction in tar. The filtering effect of the smoking device provided by the present invention is a 83.6% reduction in nicotine and a 70.9% reduction in tar. It can be seen that both have filtering effects on nicotine and tar. In comparison, the smoking device provided by the present invention reduces nicotine by 20.6% and tar by 37% relative to the traditional hookah. Compared with nicotine, the effect of filtering tar is more significant.

[0088] In summary, the present invention provides a water mist filtering smoking device, which uses water mist (i.e. atomized water) to absorb harmful components of smoke. Compared with the situation in which smoke passes through water in a traditional smoking device in the form of bubbles, only the harmful components of smoke on the surface of the bubble are absorbed by the water, and a large amount of gas inside the bubble does not contact the water, in the water mist filtering smoking device provided by the present invention, the water mist and smoke are mixed more fully, the contact area is greatly increased, which is conducive to improving the effect of reducing tar and reducing harm, and the amount of water used is greatly reduced, which is convenient to carry and use.

[0089] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above is a further detailed description of the present invention in conjunction with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
