Description

Technical Field

[0001] The invention belongs to the technical field of cigar smoke filtering, and in particular relates to a cigar smoke filtering device. Background Art

[0002] Cigars produce more smoke than flue-cured tobacco, but currently cigars sold at home and abroad do not have smoke filtering functions. When consumers smoke cigars, the smoke passes directly through the mouth and nose and is discharged from the body. Some impurities will remain in the mouth or nose, which will give consumers, especially those who are just starting out, a bad experience. In addition, during the development of cigar raw materials and products, researchers will smoke a large amount of single-ingredient or formula cigarettes for evaluation. If the excessive impurities in the smoke are not filtered, it will affect the researchers' accurate evaluation of the cigar raw materials or formulas. Summary of the invention

[0003] In view of the above technical problems, the present invention provides a cigar smoke filtering device

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

DETAILED DESCRIPTION

[0023] In order to gain a deeper understanding of the present invention, we will provide a comprehensive and detailed description of the present invention. However, the present invention has multiple implementations and is not limited to the specific examples listed herein. The presentation of these examples is intended to deepen the comprehensive understanding of the disclosure of the present invention.

[0024] Example 1

[0025] See also Figure 1 to Figure 6 As shown, the present embodiment is a cigar smoke filter device, comprising a smoke tube 10, a filter assembly 20 and a smoking mouthpiece 30. The smoke tube 10 has a smoke inlet 11. The filter assembly 20 comprises a filter cartridge 21, a porous material 22 and a filter bag 23. One end of the filter cartridge 21 is connected to the smoke tube 10. The porous material 22 is accommodated in the filter cartridge 21. The other end of the filter cartridge 21 is cone-shaped and has an air outlet at the axial end of the tail end. A plurality of filter bags 23 are sequentially nested outside the air outlet, and the filter bags 23 are detachably mounted on the cone-shaped end surface 211 of the filter cartridge 21. The smoking mouthpiece 30 is detachably connected to the cone-shaped end surface 211 of the filter cartridge 21, and a plurality of filter bags 23 are accommodated in the smoking mouthpiece 30.

[0026] A cigar is placed in the smoke inlet 11. When inhaling, the smoke first enters the filter cartridge 21 and is initially filtered by the porous material 22 to intercept larger particles and solid substances such as tar in the smoke. Then the smoke passes through multiple filter bags 23 in sequence, and the multiple filter bags 23 capture smaller particles in sequence. Finally, the smoke enters the mouth from the mouthpiece 30. The smoke is physically blocked and filtered by the porous material 22, and then the smoke is efficiently bag-dusted by the multiple filter bags 23, so that while effectively removing harmful substances in the smoke, the aroma of the cigar is retained as much as possible, providing a more balanced smoking and smoking experience.

[0027] Example 2

[0028] The difference from Example 1 is that a ring-shaped elastic sheet 12 is fixed to the inner ring of the smoke inlet 11, and the elastic sheet 12 is arranged to be inclined downward from the outer ring to the inner ring. The outer ring is fixed to the inner side of the smoke inlet 11, and the end of the inner ring is bent reversely toward the outer ring side.

[0029] The elastic sheet 12 can make the smoke inlet 11 and the cigar stick in closer contact, so that no air can enter from the inner wall during inhalation, thereby ensuring that smoke completely enters the suction nozzle from the cigar stick.

[0030] Example 3

[0031] The difference from the first embodiment is that the filter cartridge 21 is detachably connected to the smoke stack 10 , for example, the two are connected by threads, and baffles 24 are provided at both ends of the filter cartridge 21 , and filter holes are provided on the baffles 24 .

[0032] The porous material 22 can be prevented from overflowing or leaking out by the baffle 24. In addition, the smoke-receiving tube 10 of different specifications can be replaced as needed to meet the smoking filtration needs of cigars of different diameters, such as 1.64cm small crown, 1.72cm crown, 1.88cm Churchill, 2.00cm Robusto, 2.12cm Pyramid, etc., corresponding to different models.

[0033] Example 4

[0034] The difference from Example 1 lies in that an annular fixing seat 222 is fixed at intervals on the conical end surface 211 of the filter cartridge 21, and the filter bag 23 comprises an annular seat 231, a support rod 232 and a filter cloth 233. The annular seat 231 is detachably mounted on the fixing seat 222, for example, by being threadedly connected to the fixing seat 222, a plurality of support rods 232 are mounted on the annular seat 231 at intervals along the circumferential direction, the filter cloth 233 is fixed on the annular seat 231 in a bag shape, and a plurality of support rods 232 are accommodated in the filter cloth 233.

[0035] According to the filtering needs, multiple filter bags 23 and filter bags 23 of various specifications can be selected for filtering to effectively capture harmful particles. At the same time, a support rod 232 is provided in the filter bag 23 to ensure the shape of the filter bag 23 and avoid contact and overlap between adjacent filter bags 23 to affect the filtering effect.

[0036] Example 5

[0037] The difference from Example 1 is that the porous material 22 is made of activated carbon fiber, and the filter cloth 233 of the filter bag 23 is made of polytetrafluoroethylene. The activated carbon fiber can effectively intercept larger particles and solid substances such as tar in the smoke, while polytetrafluoroethylene can capture smaller particles, but has little effect on aroma molecules in gas form, thereby effectively intercepting harmful substances in cigarettes.

[0038] In other embodiments, the porous material 22 may also be made of zeolite or silica gel. Zeolite can capture smaller chemical molecules and can be used to further purify the smoke. Silica gel has good hygroscopicity and adsorption properties and can absorb moisture and harmful substances in the smoke while having little effect on the aroma components of tobacco. The filter cloth 233 may also be made of ceramic fiber, which has a good interception ability for particles and compounds in the smoke and is not prone to chemical reactions.

[0039] The contents not described in detail in the specification of the present invention belong to the prior art known to the professional and technical personnel in the field. Although the illustrative specific embodiments of the present invention are described above to facilitate the understanding of the present invention by the technical personnel in the field, it should be clear that the present invention is not limited to the scope of the specific embodiments. For the ordinary technical personnel in the field, as long as various changes are within the spirit and scope of the present invention defined and determined by the attached claims, these changes are obvious, and all inventions and creations using the concept of the present invention are protected.
