Description

Technical Field

[0001] This utility model relates to the field of cigarette holder technology, specifically a cigarette holder with activated carbon filtration function. Background Technology

[0002] During tobacco smoking, the mouthpiece serves as an auxiliary tool, its core function being to enhance smoking comfort and reduce the intake of harmful substances. Traditional mouthpieces generally lack activated carbon filtration, relying solely on a single physical barrier structure (such as sponge or ordinary fiber filter) for simple filtration. This only blocks a small amount of visible tar and ash, offering virtually no adsorption capacity for small-molecule harmful gases such as nicotine, carbon monoxide, and benzo[a]pyrene. When smoking, these harmful substances directly enter the respiratory tract and lungs with the smoke, rendering long-term use ineffective in reducing harm and failing to meet users' basic health protection needs. Therefore, we propose a mouthpiece with activated carbon filtration to address the problems mentioned in the background section. Utility Model Content

[0003] The purpose of this invention is to provide a cigarette holder with activated carbon filtration function to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cigarette holder with activated carbon filtration function, comprising a cigarette insertion section, a filter section and a mouthpiece section arranged sequentially from left to right, wherein an annular pad is fixedly connected to the inner wall of the filter section, and an activated carbon filter assembly is provided inside the filter section and on the left side corresponding to the annular pad.

[0005] The activated carbon filter assembly includes a filter shell, with mounting grooves at both ends of the filter shell. A flue gas passage is provided on the side wall of the filter shell, which communicates with the mounting grooves. An activated carbon filter element is provided inside the filter shell, and fiber cotton is filled inside the filter shell and on both sides corresponding to the activated carbon filter element.

[0006] Furthermore, a pre-filter and a post-filter are respectively inserted into the mounting slots located at the left and right ends of the filter housing.

[0007] Furthermore, a number of limiting strips are equidistantly installed around the inner wall of the filter section, and a limiting groove adapted to the limiting strips is opened on the outer surface of the filter shell.

[0008] Furthermore, internal threads are provided on the inner walls of the cigarette insertion section and the mouthpiece section near the filter section, and external threads that match the internal threads are provided on the outer surfaces of both ends of the filter section.

[0009] Furthermore, the right end of the suction nozzle section is flat and equipped with a dust cover.

[0010] Furthermore, an annular groove is provided on the outer surface of the nozzle section corresponding to its right end, and an elastic retaining ring adapted to the annular groove is fixedly connected to the inner wall of the dust cover.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model fills the gap in traditional cigarette holders that do not have activated carbon filtration function by setting an activated carbon filter element in the filter component. It can effectively adsorb tar, nicotine and some harmful gases, reduce the entry of harmful substances into the human body and meet the core needs of users for healthy smoking.

[0013] 2. This utility model achieves precise positioning and stable installation of the activated carbon filter assembly by cooperating with the limiting strip of the filter section and the limiting groove of the filter shell, combined with the supporting and sealing effect of the annular pad. This prevents the assembly from shifting or the smoke from leaking, ensuring that every puff of smoke passes through the filter layer and avoiding the problem of blind spots in traditional cigarette holders.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 A cigarette holder with activated carbon filtration function includes a cigarette insertion section 1, a filter section 2, and a mouthpiece section 3 arranged sequentially from left to right. An annular pad 21 is fixedly connected to the inner wall of the filter section 2. The annular pad 21 is made of silicone and not only provides axial support and limit for the subsequently installed activated carbon filter assembly 22, preventing the assembly from shifting towards the mouthpiece section 3, but also fills the gap between the assembly and the inner wall of the filter section through the elastic deformation of the silicone, preventing smoke leakage. An activated carbon filter assembly 22 is provided inside the filter section 2 and on the left side corresponding to the annular pad 21. This assembly is the core filter component and can achieve efficient adsorption of harmful substances.

[0023] The activated carbon filter assembly 22 includes a filter housing 221, which is made of PP plastic and has a cylindrical hollow structure. Its outer diameter matches the inner diameter of the filter section 2 to ensure no loosening after installation. Both ends of the filter housing 221 have mounting grooves 222, which are circular recesses with an inner diameter adapted to the filter screen size for precise fixing of the filter screen. Multiple flue gas passages 223, which communicate with the mounting grooves 222, are evenly distributed along the sidewall of the filter housing 221. To ensure full contact between the flue gas and the filter material, the filter housing 221 is equipped with an activated carbon filter element 224. The activated carbon filter element 224 is columnar granular activated carbon with strong adsorption capacity, which can effectively adsorb tar, nicotine and some harmful gases. The filter housing 221 is filled with fiber cotton 225 on both sides corresponding to the activated carbon filter element 224. The fiber cotton 225 is medical-grade degreased cotton, which can fix the activated carbon particles to prevent displacement and leakage, and can also initially block tar, forming a dual filtration of fiber cotton and activated carbon.

[0024] A pre-filter 226 and a post-filter 227 are respectively inserted into the mounting slots 222 at the left and right ends of the filter housing 221. Both are stainless steel filters. The pre-filter 226 is close to the cigarette insertion section 1 and can prevent the soot produced by tobacco combustion from entering the filter housing 221, thus avoiding clogging the smoke passage 223. The post-filter 227 is close to the annular pad 21 and can intercept any potentially leaked activated carbon particles, preventing them from entering the mouth with the smoke and ensuring smoking safety.

[0025] Multiple limiting strips 23 are equidistantly installed around the inner wall of the filter section 2. The limiting strips 23 are plastic protrusions integrally formed with the filter section and extend along the axial direction of the filter section. The outer surface of the filter shell 221 is provided with limiting grooves 228 that are adapted to the limiting strips 23. The limiting grooves 228 are strip-shaped grooves with a depth adapted to the height of the limiting strips. During installation, the limiting grooves 228 are aligned with the limiting strips 23 and pushed in to achieve radial fixation of the filter shell 221, preventing the components from rotating or shaking during suction and ensuring the stability of the filter structure.

[0026] Both the cigarette insertion section 1 and the mouthpiece section 3 have internal threads on their inner walls near the filter section 2. The outer surfaces of both ends of the filter section 2 have external threads that match the internal threads. The three parts are detachably connected by threads. Clockwise rotation can achieve a tight fit without smoke leakage, and counterclockwise rotation can separate them, making it easy to clean the internal e-liquid or replace the filter components, thus solving the problem of difficult cleaning of traditional one-piece mouthpieces.

[0027] The right end of the nozzle section 3 is designed as a flat mouth, which fits the contour of the human lips and makes suction more comfortable. The right end of the nozzle section 3 is equipped with a dust cover 4. The dust cover 4 is made of silicone and has a cylindrical structure with one end open. The inner diameter matches the outer diameter of the right end of the nozzle section and can be tightly fitted to the outside of the nozzle to prevent dust and impurities from adhering when not in use.

[0028] The nozzle section 3 has an annular groove 31 on its right outer surface. An elastic retaining ring 5 that matches the annular groove 31 is fixedly connected to the inner wall of the dust cover 4. The elastic retaining ring 5 is made of silicone and has good elastic deformation ability. When the dust cover 4 is put on, the elastic retaining ring 5 will be inserted into the annular groove 31 to form a stable connection, preventing the dust cover from falling off due to accidental contact and ensuring the dustproof effect is long-lasting.

[0029] Working principle: During assembly, first fix the activated carbon filter component 22, align its surface limiting groove 228 with the limiting strip 23 of the filter section 2, and push it in until it fits against the annular pad 21. Then connect the cigarette insertion section 1 and the mouthpiece section 3 to both ends of the filter section 2 through threads, and rotate clockwise until tight.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
