Description

Technical Field

[0001] The utility model relates to the technical field of smoking articles, in particular to a filter cigarette holder. Background Art

[0002] As we all know, smoking is harmful to health, but a large number of people in the society still have this habit for various reasons. However, with the development of society and the improvement of people's health awareness, more and more smokers will choose to use filter cigarette holders to purify the inhaled smoke. The filter cigarette holder usually includes a cigarette holder body with a filter cavity and a filter element arranged in the filter cavity. When the cigarette smoke passes through the filter element, the tar will be blocked and filtered, thereby reducing the harm of the tar.

[0003] The filter element filtering principle of the filter cigarette holder usually adopts the microporous jet filtering principle, that is, multiple filter holes with outlets facing the inner wall of the filter cavity are formed on the filter element. When the gas passes through the filter hole, the gas speed will be accelerated, so that the gas will be ejected from the filter hole at a faster speed. Since the gap between the filter hole and the inner wall of the filter cavity is very small, the smoke will directly hit the inner wall of the filter cavity after it comes out, so that the tar in the smoke adheres to the inner wall of the filter cavity, and the tar in the smoke is retained, thereby achieving the purpose of filtering. Such as the Chinese patent for a filter cigarette holder (CN215501319U), a double filter element filter cigarette holder (CN215501318U), etc.

[0004] However, when smoking, the smoke flows from front to back, and the filter holes are set around the filter element. When the smoke rushes directly into the filter element, it will be blocked first, and then turn through the filter holes to impact the inner wall of the filter cavity, which will weaken the impact force.

[0005] How to further optimize the structure of the filter element and improve the filtering performance and smoking taste of the cigarette holder is a direction that technicians in this field have been studying and improving. Utility Model Content

[0006] In order to overcome the shortcomings of the background technology, the utility model provides a filter cigarette holder.

[0007] The technical solution adopted by the utility model is: a filter cigarette holder, including a filter cavity, in which a filter element is arranged; the characteristic is that: at least one micropore with an outlet facing backward is formed on the filter element, and a blocking component is also arranged in the filter cavity, the blocking component is located at the rear side of the filter element and corresponds to the micropore, and there is a gap between the blocking component and the micropore.

[0008] The filter element is also provided with a plurality of filter channels with outlets facing the inner side wall of the filter cavity.

[0009] A first boss is formed at the front end of the filter element, a plurality of circumferentially arranged smoke inlet grooves are formed on the side wall of the first boss, a plurality of circumferentially arranged smoke outlet grooves are formed on the front end face of the filter element, a sealing ring is disposed on the outer sleeve of the first boss, and the sealing ring is sealed to the outer wall of the first boss, the front end face of the filter element, and the inner wall of the filter cavity, and the smoke inlet groove is connected with the smoke outlet groove to form the filtering channel.

[0010] A second boss is extended backwards from the rear end of the filter element.

[0011] The second boss is in a cone structure that is larger at the front and smaller at the back.

[0012] The number of the micro hole is one, and the micro hole is arranged at the end center of the second boss.

[0013] A smoke inlet hole connected to the micropores is formed at the front end of the filter element.

[0014] The blocking component is filter cotton.

[0015] The beneficial effect of the utility model is as follows: by adopting the above scheme, front-to-back conductive micropores are set, so that smoke can flow directly from front to back, the resistance will be smaller, the smoke flow will be smoother, and the impact force of the smoke when it is ejected from the micropores will be stronger, and at the same time, with the blocking component, when the smoke rushes out through the micropores at an accelerated speed, it can directly hit the blocking component, and the blocking component temporarily intercepts the smoke, so that the tar in the smoke adheres to the blocking component, thereby achieving the purpose of reducing tar and achieving filtration, which not only ensures reliable filtering performance, but also makes the smoking taste softer and easier.

[0021] The embodiments of the utility model are further described below in conjunction with the accompanying drawings.

[0022] Embodiment 1

[0023] like Figure 1-3 As shown, a filter cigarette holder comprises a cigarette holder body and a filter element.

[0024] The cigarette holder body comprises a cigarette socket 1, a filter cavity 2 and a mouthpiece 3 which are arranged in sequence from front to back. The cigarette holder body is formed in one piece by plastic material. Of course, the cigarette socket or the mouthpiece can also be arranged separately. The filter element 4 is arranged in the filter cavity 2. By inserting the cigarette into the cigarette socket 1 and smoking through the mouthpiece 3, the smoke generated by the cigarette can be filtered by the filter element 4 and then sucked away through the mouthpiece 3. The tar content of the filtered smoke is reduced, which not only improves the smoking taste but also reduces the harm caused by smoking.

[0025] A front-to-back conductive micropore 41 is formed on the filter element 4, a smoke inlet 45 connected to the micropore 41 is formed at the front end of the filter element 4, and a blocking component 5 is also provided in the filter cavity 2. The blocking component 5 is located at the rear side of the filter element 4 and corresponds to the micropore 41, and there is a gap between the blocking component 5 and the micropore 41. The blocking component 5 can block the micropore 41, and at the same time, the gap between the two can ensure the normal circulation of smoke to avoid complete blockage.

[0026] When smoking, the smoke will enter the filter element through the smoke inlet 45, and then flow out backwards through the micropores 41. Since the aperture of the micropores 41 is small, the speed of the smoke will be significantly accelerated when passing through the micropores 41, and will be ejected from the micropores 41 at a faster speed. The gap between the blocking component 5 and the micropores 41 is small, so when the smoke rushes out through the micropores at an accelerated speed, it can directly impact the blocking component. The blocking component temporarily intercepts the smoke, so that the tar in the smoke adheres to the blocking component, thereby achieving the purpose of reducing tar and achieving filtration.

[0027] By setting radial micropores, smoke can flow directly from front to back, with less resistance, smoother smoke flow, and stronger impact force when smoke is ejected from the micropores, which not only ensures reliable filtering performance, but also makes the smoking taste softer and more relaxing.

[0028] The number of micropores and smoke inlet holes is not limited to one, and multiple micropores may be provided. At the same time, each smoke inlet hole may correspond to one micropore, or one smoke inlet hole may correspond to multiple micropores. When the thickness of the filter element is small, micropores may be provided directly without providing smoke inlet holes. The specific amount may be reasonably adjusted according to the actual structure of the filter element.

[0029] The blocking component 5 can directly use filter cotton, such as environmentally friendly cotton. The use of filter cotton can not only form a blocking effect, but also cooperate with the micropores to form reliable filtration. At the same time, the filter cotton itself can also play the function of filtering, blocking and adsorbing impurities, thereby improving the filtration effect. In addition, the blocking component 5 can also be in other forms such as a baffle to directly block. Of course, the baffle needs to form flow holes staggered with the micropores to ensure normal flow of smoke.

[0030] In addition, the filter element 4 is also provided with a plurality of filter channels 42 with outlets facing the inner wall of the filter cavity 2 .

[0031] A first boss 43 is formed at the front end of the filter element 4, and a plurality of circumferentially arranged smoke inlet grooves 421 are formed on the side wall of the first boss 43. A plurality of circumferentially arranged smoke outlet grooves 422 are formed on the front end face of the filter element 4. A sealing ring 6 is provided on the outer sleeve of the first boss 43, and the sealing ring 6 is sealed to the outer wall of the first boss 43, the front end face of the filter element 4, and the inner wall of the filter cavity 2. The smoke inlet groove 421 is connected to the smoke outlet groove 422 to form the filtering channel 42.

[0032] When smoking, part of the smoke will flow and filter through the smoke inlet 45 and the micropores 41, and the other part will flow and filter through the filter channel 42. The flow area of ​​the filter channel 42 is very small, so the speed of the smoke will be significantly accelerated when passing through the filter channel 42. When the smoke comes out of the filter channel 42, it will directly hit the inner wall of the filter cavity. The smoke will be blocked and will instantly slow down and stay for a short time, so that the tar will adhere to the inner wall of the filter cavity, and the tar will remain at the outlet of the filter channel 42 and the corresponding side wall of the filter cavity, thereby achieving the purpose of filtering.

[0033] Of course, the filter channel can also be a small hole formed on the side wall of the smoke inlet.

[0034] By adopting the above scheme, which includes both front-to-back conductive micropores and a filter channel with the outlet facing the inner wall of the filter cavity, the tobacco tar can be retained not only on the blocking component at the rear end of the filter element, but also on the inner wall of the filter cavity, which greatly increases the adsorbable area of ​​the tobacco tar. Not only is the smoke flow area larger, but the filter mouthpiece can also absorb and filter more tobacco tar, thereby greatly improving the filtering effect, and improving the filtering performance and smoking taste of the mouthpiece.

[0035] Furthermore, the rear end of the filter element 4 extends backward to form a second boss 44, which is a cone structure with a large front and a small rear. The number of the micropore 41 is one, and the micropore 41 is arranged at the end center of the second boss 44. The second boss is arranged to ensure that the gap between the micropore and the blocking component is small, and there is enough space in the filter cavity to store smoke. The second boss with a cone structure can more conveniently observe the tar filtering situation at the micropore, which is more intuitive. Of course, the second boss 44 can also be other shapes such as a cylinder.

[0036] Embodiment 2

[0037] like Figure 4As shown, a filter cigarette holder, compared with the first embodiment, has the following main features: the filter element 4 only includes front-to-back conductive micropores 41, the second boss 44 is cylindrical, and there are multiple micropores 41, which are evenly and densely arranged.

[0038] Embodiment 3

[0039] like Figure 5 As shown, a filter cigarette holder, compared with the first embodiment, has the following main features:

[0040] The blocking component 5 adopts a blocking plate structure, and a plurality of flow holes are formed on the blocking plate, which can not only correspond to the micropores 41 but also ensure the normal flow of gas.

[0041] The filter channel 42 is a plurality of small holes formed on the side wall of the filter element, and has a simpler structure.
