Description

Technical Field

[0001] This invention relates to the field of filter cigarette holder technology, specifically disposable filter cigarette holders. Background Technology

[0002] A filter tip is an auxiliary device attached to the end of a cigarette. Through built-in filter materials (such as cellulose acetate, activated carbon, sponge, etc.), it intercepts some of the tar, nicotine and other harmful substances during smoking, reducing the amount that enters the body.

[0003] In the prior art, the applicant found, through a search, a disposable filter cigarette holder with application number "202420787267.9", which includes an integrated cigarette tube and a connector. The inner wall of the connector has an annular groove with a convex longitudinal section. An annular airbag is installed in the annular groove. The outer surface of the connector has two rectangular holes symmetrically opened, both of which are connected to the annular groove. Mounting blocks are symmetrically fixedly installed on the connector. Spring rods are fixedly installed on both sides of the two mounting blocks. A crossbar is fixedly installed at one end of the two spring rods. A pressure block is fixedly installed on the crossbar. One end of the pressure block is inserted into the rectangular hole. The connector is provided with a locking component for locking the crossbar. In this invention, a cigarette is inserted into the connector, and then the cigarette is squeezed and fixed on the connector by the cooperation of the locking component, the crossbar, the pressure block and the airbag, thereby preventing the cigarette from falling off the connector. It can use cigarettes of different diameters and effectively improves the practicality of the device.

[0004] While the above devices can accommodate cigarettes of different diameters, they are complex in structure, costly, involve many steps in installing cigarettes, and are inconvenient to operate, making them unsuitable for use by smokers. Therefore, we propose a disposable filter mouthpiece. Summary of the Invention

[0005] The purpose of this invention is to provide a disposable filter mouthpiece.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a disposable filter cigarette holder, comprising a cigarette holder body, a connecting tube disposed within the cigarette holder body, an internally threaded tube rotatably connected to the front end of the cigarette holder body, a guide tube connected to the front end of the internally threaded tube, an externally threaded tube, an elastic clamping plate, and an elastic contact pad disposed within the internally threaded tube, the elastic contact pad being connected to the elastic clamping plate, the elastic clamping plate being connected to the end face of the externally threaded tube, the externally threaded tube being threadedly connected to the internally threaded tube, and the externally threaded tube being connected to the end face of the connecting tube;

[0007] The guide tube is connected to an external mounting tube at its front end. An elastic rubber ring is provided on the inner side of the external mounting tube. A retractable silicone sheet is connected to the inner side of the external mounting tube. The inner side of the retractable silicone sheet is connected to the elastic rubber ring.

[0013] As a further embodiment of the present invention: the limiting block slides along the limiting groove, the limiting block is fixedly connected to the outer side of the connecting pipe, and filter material is installed inside the connecting pipe.

[0014] As a further aspect of the present invention: the filter material is composed of cellulose acetate and plant extracts, wherein the plant extracts account for 10%-20% (mass fraction), and the plant extracts include menthol crystals (particle size 10-50μm) and artemisia powder (particle size 5-20μm), with a mass ratio of 1:2-1:3; the filter material has a packing density of 0.3-0.5g / cm³ and a porosity of 60%-70%, thereby enhancing the tar interception rate (by 20%-30%) through the adsorption properties of the plant components.

[0015] As a further aspect of the present invention: the elastic contact pad is made of a composite material of silicone and plant essential oil microcapsules, with the plant essential oil microcapsules accounting for 5%-10% (mass fraction). The plant essential oil is selected from at least one of peppermint essential oil and honeysuckle essential oil, and the microcapsule particle size is 50-100μm. When the elastic contact pad holds a cigarette, the microcapsules are squeezed and ruptured to release the essential oil, achieving the effects of antibacterial (antibacterial rate ≥90%) and refreshing taste. The ShoreA hardness of the contact pad is 30-50.

[0016] As a further aspect of the present invention: 5%-15% (by mass) of plant gum (selected from gum arabic or gum guar) is added to the elastic rubber ring, and 10%-20% (by mass) of tea fiber (0.1-0.3 mm in length) is mixed into the stretchable silicone sheet; the plant gum increases the elongation of the elastic rubber ring to 300%-400%, and the tea fiber enhances the wear resistance of the stretchable silicone sheet (wear amount ≤0.01g / 100 frictions), and the two work together to improve the sealing performance (air leakage rate ≤5%).

[0030] Please see the appendix Figure 1 - Appendix Figure 6This invention relates to a disposable filter cigarette holder, comprising a cigarette holder body 1, a connecting tube 4 disposed within the cigarette holder body 1, an internally threaded tube 9 rotatably connected to the front end of the cigarette holder body 1, a guide tube 10 connected to the front end of the internally threaded tube 9, an externally threaded tube 6, an elastic clamping plate 7, and an elastic contact pad 8 disposed within the internally threaded tube 9, the elastic contact pad 8 being connected to the elastic clamping plate 7, the elastic clamping plate 7 being connected to the end face of the externally threaded tube 6, the externally threaded tube 6 being threadedly connected to the internally threaded tube 9, and the externally threaded tube 6 being connected to the end face of the connecting tube 4, an external mounting tube 11 being connected to the front end of the guide tube 10, an elastic rubber ring 18 disposed on the inner side of the external mounting tube 11, and a retractable silicone sheet 17 connected to the inner side of the external mounting tube 11, the inner side of the retractable silicone sheet 17 being connected to the elastic rubber ring 18. In actual use, all connections within the device are sealed, allowing a person to insert a cigarette into the device, passing it through the elastic rubber ring. The rubber ring 18 is inserted into the guide tube 10 and the internal threaded tube 9. The internal threaded tube 9 is rotated to connect with the external threaded tube 6, causing the connecting tube 4 and the external threaded tube 6 to move along the internal threaded tube 9. The guide tube 10 is funnel-shaped. The elastic clamping plate 7 contacts and squeezes the inclined surface inside the guide tube 10, causing the two elastic clamping plates 7 to move inward. The elastic clamping plates 7 approach the cigarette holder, and the elastic contact pad 8 fixedly connected to the elastic clamping plate 7 clamps the cigarette holder. Then, the person can slide along the slide groove 12 through the sliding pull ring 13, the connecting plate 15 and the slider 14, so that the support rod 16 is disengaged from the elastic rubber ring 18. The elastic rubber ring 18 tightly covers the cigarette holder, and the retractable silicone sheet 17 extends to achieve a seal. The person can then smoke through the cigarette holder body 1 and filter through the filter material 5 inside the device.

[0031] In the first embodiment, a pull ring 13 is provided on the outer side of the outer mounting tube 11, a connecting plate 15 and a support rod 16 are provided inside the outer mounting tube 11, and a sliding groove 12 is provided on the side of the outer mounting tube 11, so that a person can insert a cigarette into the device, pass it through the elastic rubber ring 18, and insert it into the guide tube 10.

[0032] The slide 12 has a square groove structure, and a slider 14 is provided inside the slide 12. The slider 14 has a square plate structure and slides along the slide 12. Personnel pass through the sliding pull ring 13.

[0033] One end of the slider 14 is fixedly connected to the inner side of the pull ring 13, and the other end of the slider 14 is fixedly connected to the outer side of the connecting plate 15, so that the connecting plate 15 and the slider 14 slide along the slide groove 12.

[0034] The connecting plate 15 has a circular plate structure. The end face of the connecting plate 15 is fixedly connected to the support rod 16. The support rod 16 is in contact with the inner side of the elastic rubber ring 18. The elastic rubber ring 18 is always in a taut state, so that the support rod 16 is separated from the elastic rubber ring 18. The elastic rubber ring 18 tightly covers the cigarette holder, and the retractable silicone sheet 17 extends to achieve a seal.

[0035] In embodiment 2, a limiting groove 2 is provided on the inner side of the mouthpiece body 1. The limiting groove 2 has a "convex" groove structure. A limiting block 3 is provided in the limiting groove 2. When the internal threaded tube 9 is rotated, the limiting block 3 is locked in the limiting groove 2 to limit the connecting tube 4.

[0036] The limiting block 3 slides along the limiting groove 2 and is fixedly connected to the outer side of the connecting pipe 4. The filter material 5 is installed inside the connecting pipe 4. The limiting block 3 slides along the limiting groove 2, and the external threaded pipe 6 rotates along the thread on the internal threaded pipe 9, so that the connecting pipe 4 and the external threaded pipe 6 can move.

[0037] In this invention, filter material 5 is composed of cellulose acetate and plant extracts, wherein the plant extracts account for 10%-20% (mass fraction). The plant extracts include menthol crystals (particle size 10-50μm) and artemisia powder (particle size 5-20μm), with a mass ratio of 1:2-1:3. The filter material 5 has a packing density of 0.3-0.5g / cm³ and a porosity of 60%-70%. The adsorption properties of the plant components enhance the tar interception rate (increasing it by 20%-30%).

[0038] In this invention, the elastic contact pad 8 is made of a composite material of silicone and plant essential oil microcapsules, with the plant essential oil microcapsules accounting for 5%-10% (mass fraction). The plant essential oil is selected from at least one of peppermint essential oil and honeysuckle essential oil, and the microcapsule particle size is 50-100μm. When the elastic contact pad 8 holds a cigarette, the microcapsules are squeezed and ruptured to release the essential oil, achieving the effects of antibacterial (antibacterial rate ≥90%) and refreshing taste. The ShoreA hardness of the contact pad is 30-50.

[0039] In this invention, 5%-15% (by mass) of plant gum (selected from gum arabic or gum guar) is added to the elastic rubber ring 18, and 10%-20% (by mass) of tea fiber (0.1-0.3 mm in length) is mixed into the stretchable silicone sheet 17. The plant gum increases the elongation of the elastic rubber ring 18 to 300%-400%, and the tea fiber enhances the wear resistance of the stretchable silicone sheet 17 (wear amount ≤ 0.01 g / 100 friction cycles). The two work together to improve the sealing performance (air leakage rate ≤ 5%).

[0040] Working principle:

[0041] First, the user inserts a cigarette into the device and rotates the internal threaded tube 9, causing the connecting tube 4 and the external threaded tube 6 to move along the internal threaded tube 9. The elastic clamping plate 7 contacts and presses against the inclined surface inside the guide tube 10. The elastic clamping plate 7 approaches the cigarette holder, and the cigarette holder is clamped by the elastic contact pad 8 fixedly connected to the elastic clamping plate 7. Then, the user can slide the pull ring 13 to disengage the support rod 16 from the elastic rubber ring 18. The elastic rubber ring 18 tightly covers the cigarette holder, and the retractable silicone sheet 17 extends to achieve a seal. The user can then smoke through the cigarette holder body 1, and the cigarette is filtered through the filter material 5 inside the device. The device has a simple structure and is easy to operate, making it convenient for users to operate and use. This concludes the entire workflow.
