Abstract
Description
Technical Field
[0001] This utility model relates to the field of cigarette holders, specifically to a filter element and a filter cigarette holder with oblique blades. Background Technology
[0002] As we all know, smoking is harmful to health, but a large number of people in society still have this habit for various reasons. However, with social development and people's health awareness, more and more smokers will choose to use filter mouthpieces to purify the smoke they inhale. Filter mouthpieces usually include a mouthpiece body with a filter chamber and a filter cartridge set in the filter chamber. When cigarette smoke passes through the filter cartridge, the tar will be blocked and filtered, thereby reducing the harm of tar.
[0003] Since the primary filtration effect is not good, existing filter elements all use secondary or even multiple filtration. For example, Chinese patent CN217771420U discloses a multi-filter cigarette holder, which uses multiple filter elements to combine filtration. This structure will result in the entire filter cigarette holder being too long and complex, which in turn leads to excessively high costs. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a filter element and filter mouthpiece with inclined blades.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A filter element for a cigarette holder with oblique blades, comprising:
[0007] The columnar filter element body includes:
[0008] The first column has a front column and a rear column that widen radially along the axial direction. The front column is provided with a plurality of first filter grooves at equal intervals in the circumferential direction, and the upper end face of the rear column is provided with a plurality of second filter grooves in the circumferential direction. The first filter grooves and the second filter grooves are connected.
[0009] The second column is connected to the rear column. The surface of the second column is provided with at least two sets of blades arranged along the axial direction. Each set of blades includes several blades arranged circumferentially along the surface of the second column, and each blade has an angle of less than 90° with the horizontal direction.
[0010] A filter ring has an inner hole with a diameter that matches the diameter of the front column. The filter ring is sleeved on the front column and is in contact with the upper end face of the rear column.
[0011] The length of the second filter tank is 0.5±0.05mm, and the width of the second filter tank is 0.5±0.05mm.
[0012] The diameter of the front column is equal to the diameter of the second column.
[0013] The blade makes an angle of 45° with the horizontal direction.
[0014] Each blade in each blade group is positioned at equal intervals on the outer surface of the second column.
[0015] Each group of leaves has the same number of leaves.
[0016] The blades of adjacent blade groups are staggered or coaxial.
[0017] A filter mouthpiece includes a mouthpiece body having an installation space arranged along an axial direction, wherein the aforementioned filter mouthpiece element with inclined blades and an adsorption filter element are sequentially arranged in the installation space.
[0018] The beneficial effects of this invention are as follows: the first column and filter ring work together to achieve microporous filtration, while the blades on the surface of the second column create a spiral airflow in the smoke, achieving two-stage interception of particles through centrifugal force, significantly improving tar and filtration efficiency while balancing suction resistance. This structure is compact, easy to manufacture, and suitable for disposable or replaceable filter mouthpieces. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0026] like Figure 1 As shown, this utility model discloses a filter element 20 with oblique blades for cigarette holders, which includes a columnar filter element body 100 and a filter ring 200 that cooperates with it.
[0027] like Figure 2 , Figure 3 and Figure 4 As shown, the columnar filter element body 100 is cylindrical in shape and includes:
[0028] The first column 110 has a feature along the axial direction (reference) Figure 2 The front column 111 and the rear column 112 (in the direction shown by the dashed line) become radially wider, that is, the diameter of the front column 111 is smaller than the diameter of the rear column, which causes the first filter tank and the second filter tank to change direction. The front column 111 is provided with a plurality of first filter tanks 113 at equal intervals around its circumference, and the upper end surface of the rear column 112 is provided with a plurality of second filter tanks 114 around its circumference. The first filter tanks 113 and the second filter tanks 114 are connected. The first filter tanks extend along the axis of the outer surface of the front column, while the second filter tanks extend radially along the upper end surface of the rear column.
[0029] The second column 120 is connected to the rear column 112. The surface of the second column 120 is provided with at least two sets of blade groups arranged along the axial direction. Each set of blade groups includes several blades 121 arranged circumferentially along the surface of the second column 120, and each blade 121 has an angle of less than 90° with the horizontal direction.
[0030] The filter ring 200 has an inner hole, the diameter of which is adapted to the diameter of the front column 111. The filter ring 200 is sleeved on the front column 111 and contacts the upper end face of the rear column 112. That is, the entire filter ring can completely or partially surround the circumference of the front column, while its lower end face contacts the upper end face of the rear column, sealing the openings of the first filter groove and the second filter groove, so that the two have a hole-like structure.
[0031] The filter ring 200 is circular, and its outer diameter matches the inner diameter of the mouthpiece body. This ensures that after the smoke enters through the front end of the mouthpiece body, it enters the filter element through the hole formed by the first filter groove 113 and the filter ring, impacts the end of the second filter groove, forming a first deflection, and then exits through the micropores formed by the filter ring and the second filter groove 200, impacting the inner wall of the mouthpiece body, forming a second deflection. See [link to relevant documentation]. Figure 5The arrows indicate the direction, and the blade assembly generates a spiral airflow, which achieves two-stage interception of particles through centrifugal force, significantly improving tar and filtration efficiency while balancing suction resistance.
[0032] The length of the second filter tank 114 l The width of the second filter groove 114 is 0.5 ± 0.05 mm. w The length is 0.5 ± 0.05 mm, which is the length in this application. l like Figure 3 As shown in the diagram, a microporous design is achieved by using a filter ring in conjunction with a second filter groove. This microporous design then filters substances such as tar in the flue gas. Simultaneously, the microporous design is achieved directly through the combination of the filter ring and the columnar filter element body. Its structure is simple and easy to manufacture.
[0033] The diameter of the front column 111 is equal to the diameter of the second column 120, and the front column, rear column and second column are integrally molded.
[0034] In this embodiment, the angle between the blade 121 and the horizontal direction a The angle is 45°, but other angles can also be used, so that the airflow is guided by the blades to form a spiral airflow.
[0035] Each blade 121 of each blade group is equally spaced on the outer surface of the second column 120, and the number of blades 121 in each blade group is the same, making the spiral airflow more stable. The number of blades can be the same as the number of second filter tanks, or less than the number of second filter tanks.
[0036] The blades 121 of adjacent blade groups are arranged in an alternating or coaxial manner. In this embodiment, a coaxial design is adopted, while in some other embodiments, an alternating arrangement can be adopted. The spiral airflow design can also disperse heat energy, increase the contact area between the smoke and the inner wall of the mouthpiece, accelerate heat transfer, significantly reduce the inhalation temperature, and reduce the burning sensation in the mouth and respiratory tract.
[0037] At the same time, the blade design on the surface of the second column is directly utilized to reduce the processing difficulty of the spiral air passage and reduce production costs.
[0038] like Figure 5 As shown, a filter mouthpiece includes a mouthpiece body 10, which has an installation space arranged along the axial direction. The installation space is provided with the above-mentioned filter mouthpiece element 20 with inclined blades and an adsorption filter element 30 in sequence.
[0039] First, micropores are used to filter tar. Then, a spiral airflow is used to slow down the airflow speed, enhance the capture of small molecule harmful substances by the subsequent adsorption filter element, and improve the filtration effect.
[0040] Adsorption filter cartridges can be made of materials such as activated carbon.
[0041] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
