[0001] This utility model relates to the field of tobacco technology, and in particular to a filter cigarette holder assembly. Background Technology

[0002] Keeping the inside of the cigarette filter dry and clean is crucial during use. Maintaining a dry and clean filter prevents the inhalation of germs or dust, thus protecting your health.

[0003] In existing technologies, a filter cover is typically used to prevent dust accumulation on the filter mouthpiece. However, while these covers effectively block dust, they are not airtight and cannot drain liquids. This makes it difficult for moisture in the filter mouthpiece to evaporate, and if liquid is present in the cover, it cannot drain out. Consequently, both the filter mouthpiece and the cover are prone to developing odors and breeding microorganisms, which can harm the user's health if inhaled. Therefore, there is an urgent need to propose a solution to these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a filter cigarette holder cover assembly to solve the problem that existing filter cigarette holders and filter cigarette holder covers are prone to microbial growth, thereby harming human health.

[0005] Based on the above concept, the technical solution adopted by this utility model is as follows:

[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] This embodiment proposes a filter cigarette holder cover assembly to solve the problem that existing filter cigarette holders and filter cigarette holder covers are prone to microbial growth, thereby harming human health.

[0031] As shown in Figures 1 and 2, the filter mouthpiece cover assembly includes a cover body 1, which has a receiving cavity that is open at one end and closed at the other end. The receiving cavity can accommodate the filter mouthpiece. A mounting hole 111 is provided through the cover body 1. The filter mouthpiece cover assembly also includes a filter element, which is installed in the mounting hole 111. The filter element has multiple through holes that can connect the receiving cavity and the atmosphere. The through holes can allow liquids and gases to pass through and can prevent dust from entering the receiving cavity.

[0032] Understandably, cigarette filters are often exposed to the atmosphere after use, and dust in the air can easily settle on the surface of the filter or even spread into its interior. Using a filter cap to cover the filter can prevent this. However, after use, the filter often retains the user's saliva. Conventional filter caps are not breathable, preventing moisture from evaporating and liquid from flowing out. This causes moisture and even liquid to accumulate inside the filter and its cap, resulting in odors and the growth of microorganisms. When using a cigarette filter, the odor affects the user experience, and the microorganisms can harm human health. The filter mouthpiece cover assembly proposed in this embodiment, by setting a filter element with through holes, can prevent dust from entering the receiving cavity, thereby keeping the filter mouthpiece clean. At the same time, when there is moisture or even liquid in the receiving cavity, since liquid and gas can pass through the through holes, moisture can evaporate into the atmosphere through the through holes, and liquid can also flow out of the receiving cavity through the through holes. This keeps the filter mouthpiece in the receiving cavity in a relatively dry state, making it less likely to produce odors and breed microorganisms, thereby strengthening the protection of the user's health and improving the user experience.

[0033] Optionally, the diameter of the through hole is 0.1μm-10μm. It is worth noting that dust particles with a diameter greater than 10μm are defined as dust. Therefore, this diameter setting can prevent dust from entering the containment cavity, while ensuring that gas and liquid can pass through the through hole. This makes it difficult for moisture or even liquid to accumulate in the containment cavity, thereby making it difficult for odors to be generated and for microorganisms to grow, thus improving the user experience.

[0034] Optionally, the filter element is sheet-shaped, with through-holes extending through the filter element along its thickness. This design effectively reduces the size of the filter element, thereby improving its portability and simplifying its installation.

[0035] For example, the filter element is a microporous breathable membrane. Microporous breathable membranes have high air permeability, mature technology, and are relatively inexpensive, improving the reliability and economy of the filter mouthpiece cap assembly. Of course, in other examples, other types of breathable elements can also be selected, as long as the pore size meets the functions of water permeability, air permeability, and dust prevention; no further restrictions are imposed here.

[0036] Optionally, the filter element is made of polytetrafluoroethylene (PTFE). This material is resistant to high temperatures and corrosion, has strong sealing properties, and excellent chemical stability, which extends the service life of the filter element and improves its reliability.

[0037] In other cases, the filter element may also be made of other materials, and no further restrictions are imposed here.

[0038] To improve the operability of the cigarette filter cap assembly, the cap body 1 may optionally include a functional part 11 and a grip part 12. A mounting hole 111 is provided in the functional part 11, and the grip part 12 is frustoconical, with its larger end connected to the functional part 11. The frustoconical shape of the grip part 12 not only reduces the volume of the cap body 1 but also facilitates user handling and gripping, thereby improving the operability of the cigarette filter cap assembly and enhancing the user experience.

[0039] Optionally, the grip portion 12 has a hanging hole 121 extending radially through it, which is used to connect a hanging accessory. This feature allows users to decorate the cover 1 with the hanging accessory, making the cover 1 more eye-catching and easy to identify. In addition, the cover 1 can be hung up with the hanging accessory, improving the convenience of storage.

[0040] For example, the hanging device is a hanging rope 3, which passes through the hanging hole 121. This arrangement facilitates the storage of the cover 1, and the hanging rope 3 can be hung up when the filter mouthpiece cover assembly is not in use.

[0041] Optionally, the cover 1 is cylindrical, and the mounting hole 111 is formed on the side wall of the cover 1. The cylindrical shape of the cover 1 can improve the portability of the filter mouthpiece cover assembly, and at the same time, this shape is consistent with the shape of most filter mouthpieces, thereby improving the adaptability of the filter mouthpiece cover assembly.

[0042] To improve the tightness of the fit between the filter mouthpiece cover assembly and the open end of the cover body 1, a sealing ring 2 may be provided at the open end of the cover body 1. The sealing ring 2 can abut against the outer periphery of the filter mouthpiece. This arrangement can improve the sealing performance between the filter mouthpiece cover assembly and the filter mouthpiece, thereby preventing dust from entering the receiving cavity from the gap between the filter mouthpiece cover assembly and the filter mouthpiece, and thus improving the reliability of the filter mouthpiece cover assembly.

[0043] Optionally, the cavity wall near the open end of the cover 1 is provided with internal threads. This feature increases the friction between the cover 1 and the filter mouthpiece, making the filter mouthpiece cover assembly more difficult to detach and improving the user experience.

[0044] In other cases, a magnet can be installed at the open end of the cover 1, which can be attracted to the filter mouthpiece to prevent the cover 1 from falling off.

[0045] Optionally, the number of mounting holes 111 is not less than two, with at least one mounting hole 111 located on the side of the cover 1 near the open end and at least one mounting hole 111 located on the side of the cover 1 near the closed end. This arrangement can improve the air and water permeability of the filter mouthpiece cover assembly, thereby ensuring a high degree of dryness within the receiving cavity, and thus improving the reliability and user experience of the filter mouthpiece cover assembly.

[0046] For example, two mounting holes 111 are provided opposite each other on the side of the cover 1 near the closed end, two mounting holes 111 are provided opposite each other on the side of the cover 1 near the open end, and two mounting holes 111 are provided opposite each other in the middle of the cover 1. This arrangement ensures that mounting holes 111 are distributed in the front, middle and rear parts of the cover 1, thereby ensuring that each part of the receiving cavity has good air and water permeability, thus greatly improving the user experience of the filter mouthpiece cover assembly.

[0047] To prevent moisture from the atmosphere from entering the containment cavity, optionally, a one-way guide is provided in the through hole, with the inlet of the one-way guide communicating with the containment cavity and the outlet of the one-way guide communicating with the atmosphere.

[0048] The usage process of the filter cigarette holder cap assembly in this embodiment is as follows:

[0049] Rotate the filter tip from the open end of the cover 1 into the receiving cavity, and the sealing ring 2 abuts against the outer circumference of the filter tip.

[0050] Moisture accumulated at the filter mouthpiece evaporates into the atmosphere through the pores on the filter element, while the pores also prevent dust from entering the receiving cavity, thus preventing dust from accumulating in the filter mouthpiece.

[0051] When using a filter cigarette holder to smoke, unscrew the filter cigarette holder from the cover 1.

[0052] Regularly inspect the appearance of the filter mouthpiece cover assembly and observe whether there is dust accumulation on the filter. If there is dust, gently sweep it with a soft brush, or soak the cover 1 in clean water for a period of time and then rinse it with clean water. After cleaning, let the cover 1 air dry naturally before reinstalling and using it.

[0053] When the filter mouthpiece cover assembly is not in use, the user can hang the lanyard 3 on a keychain or other place for easy access and carrying of the filter mouthpiece cover assembly.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention.
