Description

Technical Field

[0001] The utility model relates to the technical field of filter cigarette holders, in particular to a double-filter-core filter cigarette holder. Background Art

[0002] A filter cigarette holder, also known as a cigarette filter, is a tool designed specifically for smokers. It can reduce the smoke, tar and suspended particles produced during combustion when entering the mouth of a cigarette, thereby filtering out some of the harmful substances in the inhaled smoke and protecting human health. The working principles of the filter cigarette holder mainly include direct interception, inertial compression and diffusion precipitation. Specifically, the filter cigarette holder uses the adsorption effect of the huge specific surface area of ​​nanoparticles on tar and the catalytic effect of the particle surface to effectively reduce the content of harmful impurities such as tar in the smoke. In addition, the filter cigarette holder also has a variety of methods such as physical barrier filtration, air flow filtration and magnetic filtration.

[0003] For example, the patent number published on the China Patent Network is: 202121184778.4, and the patent name is: A dual-filter cigarette holder, wherein the first filter element includes a core body and a sealing ring. A boss is formed at the front end of the core body, and a filter channel is formed by the sidewalls of the boss and the front end surface of the core body. The sealing ring is mounted on the boss and forms a sealing engagement with the sidewalls of the boss, the front end surface of the core body, and the inner wall of the first filter chamber. Positioning bosses are formed on the sidewalls of the core body, and a smoke passage is formed between adjacent positioning bosses. The front end of the second filter element abuts against the rear end of the core body, an annular boss is formed on the middle outer wall, and an annular limiting boss extending rearward is formed on the rear end sidewall. The annular limiting boss abuts against the rear end surface of the first filter chamber and forms a smoke passage. A smoke chamber is formed inside the second filter element, and a smoke inlet and a smoke outlet are formed on the sidewalls of the second filter element. The smoke inlet is located in front of the annular boss, and the smoke outlet is located behind the annular boss. Its advantages are: simple structure, easy assembly, and good filtering effect.

The limiting rod 9 extends from one end of the adjusting rod to the outside of the connecting tube 2 and is slidably connected to the connecting tube 2.

[0030] As a technical optimization solution of the present invention, by providing an adjustment ring 8 and a limit rod 9, the connecting pipe 2 can be effectively fixed to prevent a gap from appearing between the connecting pipe 2 and the suction nozzle 1 after installation.

[0031] refer to Figure 3 The left and right sides of the bottom of the suction nozzle 1 are fixedly connected with vertical plates 10, and the vertical plates 10 are located on both sides of the adjustment ring 8. The inner side of the vertical plates 10 is fixedly connected with a guide rod 11 located at the bottom of the adjustment ring 8, and the bottom of the adjustment ring 8 is fixedly connected with a sleeve block 12 mounted on the surface of the guide rod 11, and the sleeve block 12 is slidably connected to the guide rod 11.

[0032] As a technical optimization solution of the present invention, by providing the vertical plate 10, the guide rod 11 and the sleeve block 12, the adjustment ring 8 can be guided and the horizontal movement stability of the adjustment ring 8 can be improved.

[0033] refer to Figure 3 A compression spring 13 is fixedly connected to the left side of the sleeve block 12 . The compression spring 13 is sleeved on the surface of the guide rod 11 . The side of the compression spring 13 away from the guide rod 11 contacts the surface of the vertical plate 10 .

[0034] As a technical optimization solution of the present invention, by providing a compression spring 13, the adjustment ring 8 can be supported so that the adjustment ring 8 has an elastic reset effect.

[0035] refer to Figure 3 The bottom of the vertical plate 10 is fixedly connected with a baffle 14 , and the guide rod 11 and the compression spring 13 are both located inside the baffle 14 .

[0036] As a technical optimization solution of the present invention, by providing the baffle 14, the safety of the suction nozzle 1 can be improved and the contact area between the guide rod 11 and other structures and the external environment can be reduced.

[0037] refer to Figure 3 One end of the limiting rod 9 close to the adjusting ring 8 passes through the adjusting ring 8 and extends to the left side of the adjusting ring 8, and the limiting rod 9 and the adjusting ring 8 can be slidably separated.

[0038] As a technical optimization solution of the present invention, by separating the limit rod 9 from the adjustment ring 8, it is convenient for the user to remove the filter element 3 inserted into the suction nozzle 1 and the connecting tube 2, thereby improving the convenience of replacing the filter element 3.

[0041] The working principle and usage process of the utility model are as follows: when in use, first insert the two filter elements 3 into the inside of the suction nozzle 1 and the connecting pipe 2 respectively, and then rotate the connecting pipe 2 with the pin shaft inside the connecting block 6 and the movable block 5 as the axis. When the connecting pipe 2 and the suction nozzle 1 are parallel to each other, the adjusting ring 8 can carry the limiting rod 9 to slide horizontally. When the limiting rod 9 moves to the surface of the connecting pipe 2, the suction nozzle 1 and the connecting pipe 2 are effectively connected. During the use of the suction nozzle 1, the smoke flows through the connecting pipe 2 and contacts the two filter elements 3 in turn to complete the filtration. When the filter element 3 needs to be replaced, first push the adjusting ring 8 to disengage the limiting rod 9 on its surface from contact with the connecting pipe 2. When the connecting pipe 2 rotates and swings and separates from the suction nozzle 1, the single limiting rod 9 is plugged in and pulled out, and then inserted into the filter element 3 by plugging and the filter element 3 is pulled out together.

[0042] To sum up: the double-filter filter cigarette holder inserts the two filter elements 3 into the inside of the suction nozzle 1 and the connecting tube 2 respectively, and then rotates the connecting tube 2 with the pin shaft inside the connecting block 6 and the movable block 5 as the axis. When the connecting tube 2 and the suction nozzle 1 are parallel to each other, the suction nozzle 1 and the connecting tube 2 are effectively connected. At the same time, after the connecting tube 2 and the suction nozzle 1 are separated, the two filter elements 3 can be quickly replaced, which increases the operation space for replacing the filter element 3. The installation method of the filter element 3 inside the existing filter cigarette holder is improved, and the auxiliary plug-in and stacking method is used for installation, so that the contact area of ​​the filter element 3 located on the inner side with the external environment is expanded after plugging, thereby avoiding affecting the operation space for replacing the filter element 3.
