Description

Technical Field

[0001] This utility model relates to a cigarette auxiliary filtration tool, a wet cigarette filter with a liquid bladder, and in particular a filter that removes some harmful smoke particles by wet filtration before the smoke enters the mouth during smoking. Background Technology

[0002] The smoke produced by burning cigarettes contains a large amount of tar, nicotine and suspended particles, and cigarette filters have a limited adsorption rate for these harmful substances. Therefore, the invention of a wet cigarette filter is of great significance to improving the health of the nation. Utility Model Content

[0003] A wet cigarette filter with a liquid bladder is a device designed to assist smokers in filtering cigarette smoke, specifically a filter that wet-filters cigarette smoke before it enters the mouth, adsorbing some harmful smoke particles. It mainly consists of a filter housing, a liquid bladder, and a cigarette filter core, among other key components. Figure 1 , Figure 7 As shown.

[0004] The filter housing is a hollow tubular structure, consisting of a front mouthpiece cavity, a middle wet filter cavity, and a rear dry filter cavity. The wet filter cavity has a liquid bladder communication hole at its top, and a pointed conical fixing rod fixed to the wet filter cavity is located in the middle of the liquid bladder communication hole. The pointed conical fixing rod has an upward-pointing cone in its middle. The rear of the dry filter cavity has a slightly outward-curving filter mouthpiece. Figure 8 , Figure 9 As shown.

[0005] The aforementioned wet cigarette filter with a liquid bladder consists of a wet filter chamber in the middle of the filter housing filled with a cigarette filter core, and a dry filter chamber at the rear of the filter housing filled with a dried cigarette filter core. A liquid bladder sealing membrane and a liquid bladder are sequentially adhered to the outside of the liquid bladder connecting hole at the top of the wet filter chamber. The liquid bladder and the liquid bladder sealing membrane are sealed and filled with cigarette filter liquid. Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown.

[0006] As a further optimization of this solution, the diameter of the end hole of the mouthpiece cavity in the filter housing of this utility model is slightly smaller than the diameter of the cigarette filter, and the depth of the end hole of the mouthpiece cavity is two-thirds of the length of the cigarette filter. This allows the mouthpiece cavity to fully enclose the cigarette filter and also prevents the mouthpiece cavity from being burned when the cigarette burns out. Figure 5 , Figure 6 As shown.

[0007] As a further optimization of this solution, the liquid bladder of this utility model is an outwardly convex hemispherical cavity. The amount of cigarette filter liquid filled in the liquid bladder and its sealing membrane allows the cigarette filter cotton core in the wet filter cavity to reach an appropriate level of humidity, which neither affects the passage of smoke nor hinders the absorption of harmful smoke particles in the smoke. Figure 3 , Figure 7 As shown.

[0008] As a further optimization of this solution, the liquid bladder of this utility model is made of a soft shell material, and the liquid bladder sealing membrane is made of soft nylon material. Squeezing the liquid bladder into the connecting hole with a finger causes the sealing membrane to expand into the connecting hole, piercing the sealing membrane with a sharp cone. Cigarette filter liquid can then be sprayed into the wet filter chamber through the piercing hole, wetting the cigarette filter core. Figure 7 As shown. Attached Figure Description

Detailed Implementation

[0020] This utility model relates to a wet cigarette filter with a liquid bladder, a device for auxiliary filtration during smoking, and specifically a filter tool that can wet filter cigarette smoke before it enters the mouth, adsorbing some harmful smoke particles. It mainly consists of a filter housing 10, a liquid bladder 21, and a cigarette filter core 24, etc. Figure 1 , Figure 7 As shown.

[0021] The filter housing 10 of this utility model is a hollow tubular structure, consisting of a front mouthpiece cavity 13, a middle wet filter cavity 11, and a rear dry filter cavity 12. The wet filter cavity 11 has a liquid bladder communication hole 101 at its top. A pointed conical fixing rod 102, fixed to the wet filter cavity 11, is located in the middle of the liquid bladder communication hole 101. A pointed cone 103 pointing upwards is located in the middle of the pointed conical fixing rod 102. The rear of the dry filter cavity 12 has a slightly outward-curving filter mouthpiece 14. Figure 8 , Figure 9 As shown.

[0022] The structure of this utility model consists of a wet filter chamber 11 in the middle of the filter housing 10 filled with a cigarette filter cotton core 24, and a dry filter chamber 12 at the rear of the filter housing 10 filled with a cigarette drying cotton core 25. A liquid bladder sealing membrane 22 and a liquid bladder 21 are sequentially adhered to the outside of the liquid bladder connecting hole 101 at the top of the wet filter chamber 11. The liquid bladder 21 and the liquid bladder sealing membrane 22 are sealed and filled with cigarette filter liquid 23. Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown.

[0023] In this invention, the diameter of the end hole of the mouthpiece cavity 13 in the filter housing 10 is slightly smaller than the diameter of the cigarette filter 31, and the depth of the end hole of the mouthpiece cavity 13 is two-thirds of the length of the cigarette filter 31. The mouthpiece cavity 13 can fully enclose the cigarette filter 31 and also prevent burns to the mouthpiece cavity 13 when the cigarette burns out. Figure 5 , Figure 6 As shown.

[0024] The liquid bladder 21 of this invention is an outwardly convex hemispherical cavity. The amount of cigarette filter liquid 23 filled in the liquid bladder 21 and the liquid bladder sealing membrane 22 allows the cigarette filter cotton core 24 in the wet filter cavity 11 to reach an appropriate humidity level, which neither affects the passage of smoke nor hinders the absorption of harmful smoke particles in the smoke. Figure 3 , Figure 7 As shown.

[0025] The liquid bladder 21 of this invention is made of a soft shell material, and the liquid bladder sealing membrane 22 is made of soft nylon material. Squeezing the liquid bladder 21 into the liquid bladder connecting hole 101 with a finger causes the liquid bladder sealing membrane 22 to expand into the liquid bladder connecting hole 101. The liquid bladder sealing membrane 22 is pierced by the pointed cone 103, allowing the cigarette filter liquid 23 to be sprayed into the wet filter chamber 11 through the piercing hole, thus wetting the cigarette filter cotton core 24. Figure 7 As shown.

[0026] The working process of a wet cigarette filter with a liquid bladder is as follows: When the user is about to smoke, they press the liquid bladder 21 into the liquid bladder connecting hole 101 with their finger, causing the liquid bladder sealing membrane 22 to expand into the liquid bladder connecting hole 101. When the liquid bladder sealing membrane 22 expands to the position of the pointed cone fixing rod 102, it will be pierced by the pointed cone 103 to form a small hole. Continuing to press the liquid bladder 21 causes the internal cigarette filter liquid 23 to be sprayed into the wet filter chamber 11 through the pierced hole, thus wetting the cigarette filter cotton core 24. Figure 6 , Figure 7 As shown.

[0027] Insert the cigarette filter 31 of a cigarette 30 into the mouthpiece cavity 13, light the cigarette 30, and inhale through the mouthpiece 14 at the end of the filter housing 10 to create negative pressure in the mouth. Under the action of atmospheric pressure and the pressure difference in the mouth, the cigarette smoke enters the wet filter cavity 11 through the cigarette filter 31 and forms a porous contact with the moist cigarette filter cotton core 24. The moist cigarette filter cotton core 24 cools and liquefies the tar in the smoke and adsorbs it. A large number of suspended particles in the smoke are also adsorbed. The smoke after being adsorbed and filtered by the moist cigarette filter cotton core 24 enters the dry filter cavity 12 and is dried by the cigarette drying cotton core 25 before entering the mouth. After the cigarette smoke has been wet filtered and dried, a large amount of tar and suspended particles have been removed without affecting the taste.
