Description

Technical Field

[0001] The utility model specifically relates to a cigarette holder filter element with a built-in filter element and a 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

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] The utility model discloses a cigarette holder filter element with a built-in filter element, which comprises:

[0032] A first filter element having a first gas channel arranged along an axial direction;

[0033] At least one second filter element is placed in the gas channel, and a plurality of first micropores are provided between the second filter element and the first filter element, and a blocking component is provided on the rear side of the first micropores, and a gap is provided between the blocking component and the first micropores. The rear side refers to the rear side of the smoke flow direction, and the bottom in the following text is equivalent to the rear side.

[0034] When there are multiple second filter elements, the second filter elements can be arranged side by side inside the first filter element, or the second filter elements can be nested with each other and placed inside the first filter element, that is, the first filter element is provided with a second filter element, and the second filter element is also provided with a second filter element, so that the filtering effect of tar in the flue gas is improved through multiple filtration.

[0035] Example 1

[0036] The utility model provides a cigarette holder filter element with a built-in filter element, which comprises:

[0037] The first filter element 1 has an air inlet 11 at its upper end and an air outlet 12 at its lower end, and a smoke cavity is formed therebetween. The upper end of the first filter element 1 is extended outwardly to form a mounting portion, so that it can be directly mounted in the cigarette holder, and a gap is formed between the first filter element 1 and the inner wall of the cigarette holder.

[0038] The second filter element 2 is placed on the inner side of the smoke cavity of the first filter element 1, and divides the smoke cavity into an upper smoke cavity 13 and a lower smoke cavity 14. The second filter element is provided with a plurality of grooves 21 in the circumferential direction, and the grooves 21 cooperate with the inner wall of the first filter element 1 to form a first micropore 3, and the first micropore 3 connects the upper smoke cavity 13 and the lower smoke cavity 14. The cooperation between the second filter element 2 and the first filter element 1 can achieve support by utilizing the variable diameter mode of the first filter element, or by utilizing the design of the support boss on the inner wall of the first filter element.

[0039] The inner wall of the first filter element 1 extends inwardly in the circumferential direction to form a blocking boss 15 , and the blocking boss 15 is located below the first micropore 3 .

[0040] By arranging a blocking boss below the first microhole 3, the smoke entering the upper smoke cavity can directly hit the blocking boss after rushing out through the first microhole at an accelerated speed. Figure 2 As shown by the arrow, the blocking boss temporarily intercepts the smoke, causing the tar in the smoke to adhere to the blocking boss, thereby reducing the tar and achieving filtration. The remaining tar will flow downward along the side wall of the lower smoke cavity and out through the air outlet, which will not cause tar to accumulate in the first filter element for a long time, making it easier to clean the mouthpiece later.

[0041] The inner wall of the first filter element 1 extends inwardly in the circumferential direction to form a supporting boss 16 for supporting the second filter element 2. The supporting boss 16 is arranged above the blocking boss 15. The thickness of the supporting boss is smaller than that of the blocking boss, so that the smoke can directly hit the blocking boss without being blocked by the supporting boss, thereby ensuring that the first micropore is not blocked.

[0042] In addition, a limiting boss can be set on the supporting boss to cooperate with the groove to limit the second filter element. In this way, the number of blocking bosses is consistent with the number of first micropores, and they are respectively located under the first micropores to play the role of adhering tar.

[0043] A plurality of second micropores 17 are provided at intervals on the side wall of the upper smoke cavity 13. The design of the second micropores 17 allows smoke to escape therefrom and hit the inner wall of the cigarette holder, where tar is attached to the inner wall, thus playing the role of the first layer of filtering.

[0044] The bottom of the first filter element is through-connected, that is, it is through-connected along the axis from top to bottom, so as to increase the flow speed of the smoke.

[0045] The lower end of the first filter element 1 is closed, and a plurality of air outlets 12 are arranged circumferentially at the closed end. The design of multiple air outlets serves to disperse the smoke, making the smoke discharge softer and smoother.

[0046] The air outlets 12 are distributed along the circumference, or in a matrix, and are designed according to needs. The size of the air outlets is preferably a size that can discharge tar.

[0047] The air outlet 12 is a notch formed by extending the end surface of the closed end of the first filter element 1 toward the side wall of the first filter element 1, thereby accelerating the discharge of tar flowing down the side wall and preventing it from accumulating at the closed end.

[0048] A cigarette holder comprises a filter cavity, in which the cigarette holder filter element with the built-in filter element is arranged. By installing the cigarette holder filter element with the built-in filter element, the smoke can circulate up and down, thereby accelerating the flow rate of smoke. In addition, by utilizing the first micropore formed between the second filter element and the first filter element, the smoke passes through the first micropore and is accelerated to hit a blocking boss, so that tar adheres to the blocking boss, thereby realizing a second filtering, achieving the purpose of reducing tar and realizing filtering, not only ensuring reliable filtering performance, but also making the smoking taste softer and easier.

[0049] Example 2

[0050] The second filter element is placed inside the first gas channel of the first filter element, and the second filter element has a smoke cavity, and a first micropore is arranged on the side wall of the smoke cavity.

[0051] That is, the second filter element is an ordinary cigarette holder filter element, which is arranged inside the first filter element through miniaturization. The first micropores arranged on its side accelerate the discharge of smoke and make the smoke hit the inner wall of the first filter element, and then tar is attached to the inner wall of the first filter element to achieve the filtering effect, that is, the tar is filtered by double filtration.

[0052] Example 3

[0053] The second filter element is placed on the inner side of the first gas channel of the first filter element, and the second filter element has a second gas channel arranged along the axial direction, and a blocking portion is provided on the axis of the second gas channel, and the blocking portion is located on the rear side of the second gas channel, and a notch connected to the gas channel is circumferentially provided on the blocking portion, and the blocking portion is arranged in the direction of smoke flow and has a certain blocking effect on the smoke.

[0054] The second filter element in this embodiment has a second gas channel arranged in an axial direction, and a blocking component for blocking the gas flow direction is arranged on the axis of the second gas channel, such as a baffle or a sleeve 4 or the like, so that the smoke discharged through the second gas channel hits the blocking component and the tar in the smoke adheres to the blocking component, thereby filtering the tar.

[0055] Meanwhile, the overall structure in Example 1 can also be used as the second filter element in this embodiment.

[0056] The embodiments should not be regarded as limiting the present invention, but any improvements based on the spirit of the present invention should be within the protection scope of the present invention.
