Description

Technical Field

[0001] This utility model relates to a cigarette auxiliary filter, a cigarette filter with a cotton core moistened by injection, and in particular a filter that uses a method of injecting filtrate to moisten the cotton core, thereby using the moistened cotton core to adsorb harmful substances in cigarette smoke. Background Technology

[0002] Cigarette smoke contains a large amount of tar and harmful particulate matter, and cigarette filters have a limited adsorption rate for these harmful substances. Smoking is harmful to health, so it is necessary to invent a device that uses an injection method to moisten a cotton wick to filter cigarette smoke. Utility Model Content

[0003] A cigarette filter with an injection-wetted cotton wick is an auxiliary filter for cigarette smoke. Specifically, it uses an injection of filtrate to wet the cotton wick, thereby adsorbing harmful substances in the cigarette smoke. It mainly consists of a tubular filter assembly and a liquid injection assembly. Figure 1 , Figure 2 , Figure 3 As shown.

[0004] The tubular filter assembly consists of a front casing with a rear casing fitted into the bottom opening of the front casing. The rear casing can slide axially within the front casing. The interior of the rear casing is filled with a section of dry cotton. Sufficient filter cotton is filled both the interior of the rear casing and the interior of the front casing. A certain gap is provided between the dry cotton and the filter cotton inside the rear casing. Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown.

[0005] The front casing mainly consists of two hollow tubular sections: a mouthpiece tube and a piston cavity. The outer diameter of the mouthpiece tube is smaller than the outer diameter of the piston cavity, and the inner diameter of the mouthpiece tube is slightly smaller than the outer diameter of the cigarette filter. A spoke-shaped support is installed inside the piston cavity, and a piston rod is fixed to the spoke support. The axis of the piston rod coincides with the axis of the piston cavity. Figure 7 As shown.

[0006] The rear casing mainly consists of two tubular sections: a cotton core lumen and a smoking mouthpiece. Four support grooves are evenly distributed on the inner wall of the cotton core lumen. Figure 8 As shown.

[0007] The described liquid storage injection assembly has needle cap fixing brackets positioned and installed on four bracket limiting grooves on the inner wall of the cotton core tube. A rubber cap is embedded in the countersunk hole in the middle of the needle cap fixing bracket. A rubber piston is installed at the end of the piston rod inside the piston tube, forming a piston seal. The space between the piston tube and the rubber piston seal contains the flue gas filtrate. The needle tip at the bottom of the piston tube is inserted into the rubber cap. Figure 4 , Figure 5 , Figure 6 As shown.

[0008] As a further optimization of this solution, the outer diameter of the cotton core cavity in the rear shell of this utility model is equal to the inner diameter of the piston cavity in the front shell. The cotton core cavity is inserted into the piston cavity to form a clearance seal that allows for axial movement. Figure 3 , Figure 4 As shown.

[0009] As a further optimization of this solution, the needle tip of the needle at the bottom of the piston tube of this utility model is inserted into the rubber cap to form a seal. When not in use, the flue gas filtration liquid inside the piston tube will not flow out, thus keeping the filter cotton in the piston tube cavity and the cotton core cavity dry. When in use, the front tube shell is pushed along the axial direction to the rear tube shell side, causing the rubber piston installed at the end of the piston rod, the piston tube, and the needle at the bottom of the piston tube to move accordingly. The needle tip pierces the rubber cap, eliminating the sealing effect of the rubber cap. The rubber piston continues to move towards the bottom of the piston tube, squeezing the flue gas filtration liquid out of the piston tube through the needle. The flue gas filtration liquid flowing out from the needle can wet the filter cotton in the piston tube cavity and the cotton core cavity, forming a moist cotton core. Figure 4 , Figure 5 , Figure 6 As shown. Attached Figure Description

Detailed Implementation

[0020] This utility model relates to an auxiliary filter for cigarette smoke, a cigarette filter with a cotton wick moistened by injection, and particularly a filter that uses an injection of filtrate to moisten the cotton wick, thereby adsorbing harmful substances in cigarette smoke. It mainly consists of a tubular filter assembly and a liquid injection assembly. Figure 1 , Figure 2 , Figure 3 As shown.

[0021] The tubular filter assembly of this utility model consists of a rear tubular shell 12 fitted into the bottom opening of a front tubular shell 11. The rear tubular shell 12 can slide axially within the front tubular shell 11. A section of dry cotton 20 is filled inside the rear tubular shell 12. Sufficient filter cotton 19 is filled both inside the rear tubular shell 12 and the front tubular shell 11. A certain gap is provided between the dry cotton 20 and the filter cotton 19 inside the rear tubular shell 12. Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown.

[0022] The front casing 11 of this utility model mainly consists of two hollow tubular sections: a mouthpiece tube 111 and a piston cavity 112. The outer diameter of the mouthpiece tube 111 is smaller than the outer diameter of the piston cavity 112, and the inner diameter of the mouthpiece tube 111 is slightly smaller than the outer diameter of the cigarette filter. A spoke-shaped spoke support 113 is installed inside the piston cavity 112, and a piston rod 114 is fixed on the spoke support 113. The axis of the piston rod 114 coincides with the axis of the piston cavity 112. Figure 7 As shown.

[0023] The rear casing 12 of this utility model mainly consists of two tubular sections: a cotton core cavity 121 and a smoking nozzle 122. Four support limiting grooves 123 are evenly distributed on the inner wall of the cotton core cavity 121. Figure 8 As shown.

[0024] The liquid storage and injection assembly of this utility model has needle cap fixing brackets 17 positioned and installed on four bracket limiting grooves 123 on the inner wall of the cotton core tube cavity 121. A rubber cap 18 is embedded in the countersunk hole in the middle of the needle cap fixing bracket 17. A rubber piston 13 is installed at the end of the piston rod 114 in the piston tube cavity 112. The rubber piston 13 is inserted into the piston tube 14 to form a piston seal. The space sealed by the piston tube 14 and the rubber piston 13 contains the flue gas filtrate 16. The needle tip of the needle 15 at the bottom of the piston tube 14 is inserted into the rubber cap 18. Figure 4 , Figure 5 , Figure 6 As shown.

[0025] In this invention, the outer diameter of the cotton core cavity 121 of the rear shell 12 is equal to the inner diameter of the piston cavity 112 of the front shell 11. The cotton core cavity 121 is inserted into the piston cavity 112 to form a clearance seal fit that allows axial movement. Figure 3 , Figure 4 As shown.

[0026] In this invention, the needle tip of the needle 15 at the bottom of the piston tube 14 is inserted into the rubber cap 18 to form a seal. When not in use, the flue gas filtration liquid 16 inside the piston tube 14 will not flow out, thus keeping the filter cotton 19 in the piston tube cavity 112 and the cotton core cavity 121 dry. When in use, the front tube shell 11 is pushed axially towards the rear tube shell 12, causing the rubber piston 13, piston tube 14, and needle 15 at the bottom of the piston tube 14 to move accordingly. The needle tip of the needle 15 pierces the rubber cap 18, eliminating its sealing effect. The rubber piston 13 continues to move towards the bottom of the piston tube 14, squeezing the flue gas filtration liquid 16 out of the piston tube 14 through the needle 15. The flue gas filtration liquid 16 flowing out from the needle 15 wets the filter cotton 19 in the piston tube cavity 112 and the cotton core cavity 121, forming a moist cotton core. Figure 4 , Figure 5 , Figure 6 As shown.

[0027] The working process of an injection-moistened cotton wick cigarette filter is as follows: When the user is about to smoke, the rear tube 12 is fixed, and the front tube 11 is pushed backward by hand. The rubber piston 13 installed at the end of the piston rod 114 also moves to the right. Since the smoke filter liquid 16 in the piston tube 14 is in a sealed state, the piston tube 14 and the needle 15 at the bottom of the piston tube 14 also move backward until the needle tip of the needle 15 pierces the rubber cap 18. The sealing effect of the rubber cap 18 is eliminated, and the sealing effect of the smoke filter liquid 16 is eliminated. The rubber piston 13 continues to move towards the bottom side of the piston tube 14, squeezing the smoke filter liquid 16 out of the piston tube 14 through the needle 15. The smoke filter liquid 16 flowing out from the needle 15 can wet the filter cotton 19 in the piston tube cavity 112 and the cotton wick cavity 121 to form a moistened cotton wick.

[0028] Insert the end of the cigarette filter into the mouthpiece tube 111 of the front shell 11, light the cigarette, and inhale through the mouth into the mouthpiece 122 of the rear shell 12. The smoke produced by the burning cigarette flows through the cigarette filter into the piston tube 112. Under the action of the moist cotton wick, some of the tar and soot particles in the cigarette smoke are adsorbed. The cigarette smoke filtered by the moist cotton wick enters the cotton wick tube 121, and under the action of the dry cotton 20, most of the moisture components in the cigarette smoke are adsorbed before entering the mouth through the mouthpiece tube 111. This process completes the filtration of some harmful components in the cigarette smoke, which can protect the user's health.
