Description
Technical Field
[0001] This utility model relates to the field of electronic cigarette technology, and in particular to a mouthpiece cap and a filter mouthpiece. Background Technology
[0002] A filter mouthpiece is an auxiliary smoking tool that filters harmful substances in e-cigarettes. Through different filtration principles, such as physical barrier filtration, airflow filtration, and magnetic filtration, it effectively reduces harmful components like tar and nicotine in the smoke, thereby minimizing the health hazards of smoking. To protect the mouthpiece tip from contamination and ensure hygienic use, a mouthpiece cap is usually installed on the tip.
[0003] Traditional cigarette holder caps typically feature a closed cap body. After being installed on the cigarette holder, a sealed space is formed between the cigarette holder and the cap to prevent dust. However, this type of cigarette holder cap, due to its non-breathable space, can cause saliva to accumulate on the cigarette holder, leading to bacterial growth and resulting in low hygiene. Alternatively, a cap body with simple ventilation holes can be used, but this type of cigarette holder cap is less effective at preventing dust.
[0004] Therefore, there is an urgent need to provide a cigarette holder cap and filter that can take into account both dustproof and breathable properties. Utility Model Content

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.
[0031] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0033] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0034] Reference Figure 1 This embodiment proposes a cigarette holder cap, including a main cap body 1 and an adjusting cap 2. The main cap body 1 can be connected to the cigarette holder head. A ventilation channel 11 is provided inside the main cap body 1. The adjusting cap 2 is connected to the end of the main cap body 1 away from the cigarette holder head. A first ventilation hole 12 is provided on the main cap body 1, and a second ventilation hole 21 is provided on the adjusting cap 2. The adjusting cap 2 can move relative to the main cap body 1, so that the first ventilation hole 12 and the second ventilation hole 21 at least partially overlap or are completely offset, so as to realize the ventilation channel 11 is connected to or isolated from the outside. This cigarette holder cap has a flexible adjustment function. The user can operate the adjusting cap 2 according to the actual situation to make the ventilation channel 11 connected to or isolated from the outside, realizing the free switching between dust protection and ventilation, and has strong versatility.
[0035] After using the filter mouthpiece, the user can connect the mouthpiece cap to the mouthpiece head and operate the adjusting cover 2 to at least partially overlap the first vent 12 and the second vent 21, allowing the ventilation channel 11 to connect with the outside, ensuring ventilation inside the mouthpiece cap and keeping the mouthpiece head dry. If the filter mouthpiece is not used for a long period, the user can connect the mouthpiece cap to the mouthpiece head and operate the adjusting cover 2 to completely offset the first vent 12 and the second vent 21, isolating the ventilation channel 11 from the outside and ensuring a sealed internal environment for dust prevention. Additionally, the user can control the degree of overlap (partial or complete overlap) of the first vent 12 and the second vent 21 by operating the adjusting cover 2 to control the ventilation area and thus adjust the ventilation intensity.
[0036] Reference Figure 2The adjusting cap 2 is coaxially arranged and rotatably connected to the main cap body 1. In terms of manufacturing and assembly, the coaxial structure of the adjusting cap 2 and the main cap body 1 is easier to produce and assemble, reducing production and manufacturing costs, and maintaining higher adjustment precision. It accurately controls the overlap of the first vent hole 12 and the second vent hole 21. Furthermore, the rotatable connection between the adjusting cap 2 and the main cap body 1 on a coaxial basis not only reduces the overall volume of the cigarette holder cap, saving space and making it easier to carry, but also prevents gaps from forming at the connection point, avoiding the entry of liquids or dust from increasing the cleaning burden. Of course, in other embodiments, the adjusting cap 2 and the main cap body 1 can also be slidably connected, allowing the adjusting cap 2 to slide radially along the main cap body 1 so that the first vent hole 12 and the second vent hole 21 at least partially overlap or are completely offset.
[0037] Furthermore, the side wall of the main cap 1 is provided with a first slide rail 13 extending in the circumferential direction, the side wall of the adjusting cover 2 is provided with a first protrusion 22 extending in the circumferential direction, the first protrusion 22 is placed in the first slide rail 13 and the first protrusion 22 can move in the first slide rail 13, and / or, the side wall of the adjusting cover 2 is provided with a second slide rail extending in the circumferential direction, the side wall of the main cap 1 is provided with a second protrusion extending in the circumferential direction, the second protrusion is placed in the second slide rail and the second protrusion can move in the second slide rail. In other words, of the main cap 1 and the adjusting cover 2, one side wall is provided with a slide extending in the circumferential direction, and the other side wall is provided with a protrusion extending in the circumferential direction. Alternatively, the main cap 1 is provided with a slide and a protrusion, and the adjusting cover 2 is also provided with a slide and a protrusion. The coaxial rotation connection is completed by the movement of the protrusion in the slide. The slide also provides guidance and directional restriction for the movement of the protrusion, ensuring that the relative rotation between the adjusting cover 2 and the main cap 1 can be completed smoothly.
[0038] It should be explained that the width of the first protrusion 22 should be slightly smaller than the width of the first slide 13 to avoid the first protrusion 22 and the first slide 13 fitting too tightly, which would prevent the first protrusion 22 from moving within the first slide 13 and thus hinder the rotational movement of the adjusting cover 2. Similarly, the width of the second protrusion should be slightly smaller than the width of the second slide to avoid the second protrusion and the second slide fitting too tightly, which would prevent the second protrusion from moving within the second slide.
[0039] Reference Figure 2 and Figure 3In this embodiment, a first slide rail 13 is provided on the main cap body 1, and a first protrusion 22 is provided on the adjusting cover 2. The first protrusion 22 is placed inside the first slide rail 13 to achieve a coaxial rotatable connection between the main cap body 1 and the adjusting cover 2. Preferably, the first slide rail 13 extends circumferentially around the side wall of the main cap body 1 and is continuous, that is, the first slide rail 13 extends around the side wall of the main cap body 1, and the first protrusion 22 also extends circumferentially around the side wall of the adjusting cover 2. This reduces manufacturing difficulty, and at the same time, it can disperse stress, avoid local wear, and improve overall durability. Of course, in other embodiments, the first slide rail 13 can extend continuously around the side wall of the main cap 1, while the first protrusion 22 extends at intervals around the side wall of the adjusting cover 2. Alternatively, the first slide rail 13 can extend at intervals around the side wall of the main cap 1, and the first protrusion 22 can also extend at intervals around the side wall of the adjusting cover 2. It is only necessary to ensure that when the first protrusion 22 moves within the first slide rail 13, causing the adjusting cover 2 to rotate relative to the main cap 1, the first vent hole 12 and the second vent hole 21 can at least partially overlap or completely offset. The second slide rail and the second protrusion are configured in the same way as above.
[0040] In addition, considering the wear resistance of the first slide 13 and the first protrusion 22, lubricating material or coating can be applied to the inside of the first slide 13 and / or the first protrusion 22 to reduce wear and extend service life.
[0041] Reference Figures 4 to 5 The first vent 12 is located on the end face of the main cap 1, and correspondingly, the second vent 21 is also located on the end face of the adjusting cap 2. The first vent 12 and the second vent 21 are respectively located on the end faces of the main cap 1 and the adjusting cap 2, ensuring that the airflow channel is straight during ventilation and improving the ventilation effect. In other embodiments, the first vent 12 can also be located on the side wall of the main cap 1, and the second vent 21 can also be located on the side wall of the adjusting cap 2. When the adjusting cap 2 is rotated, the first vent 12 and the second vent 21 can at least partially overlap or completely offset.
[0042] Furthermore, at least two first vent holes 12 are provided, and the at least two first vent holes 12 are arranged symmetrically along the axis of the main cap body 1. At least two second vent holes 21 are also provided, and the at least two second vent holes 21 are arranged symmetrically along the axis of the adjusting cover 2. The symmetrical arrangement of the first vent holes 12 and the second vent holes 21 makes it easier for the user to find the symmetrical position when operating the adjusting cover 2, and makes it easier to achieve complete overlap and complete offset of the first vent holes 12 and the second vent holes 21. In addition, the symmetrical arrangement of the first vent holes 12 and the second vent holes 21 can also improve the uniformity of ventilation, prevent uneven load, and improve the aesthetics of the mouthpiece cap.
[0043] Both the first vent 12 and the second vent 21 are fan-shaped holes. Since the first vent 12 is located on the end face of the main cap 1 and the second vent 21 is located on the end face of the adjusting cover 2, and both the end faces of the main cap 1 and the adjusting cover 2 are circular, setting fan-shaped holes as vents on circular end faces is easier to implement in the manufacturing process and also easier to adjust the angle. In this embodiment, five of each type of vent are provided. Because the first vent 12 is rotationally symmetrically arranged along the axis of the main cap 1 and the second vent 21 is rotationally symmetrically arranged along the axis of the adjusting cover 2, the fan-shaped angle of both the first and second vents is 36 degrees. This means that by rotating the adjusting cover 2 by 36 degrees, the user can achieve complete overlap and complete offset of the first and second vents. In other embodiments, two, three, or six of each type of vent can be provided.
[0044] Refer again Figure 1 The adjustment cover 2 is fitted onto the outside of the main cap 1 to facilitate user operation. The outer wall of the adjustment cover 2 is provided with a grip part with anti-slip texture 23, which increases the surface roughness of the grip part and improves the friction when in contact with the palm, so as to maintain a stable grip even when the hands are sweaty or wet.
[0045] The end face of the adjusting cover 2 is recessed with a receiving groove 24. The receiving groove 24 is located on the side of the second vent 21 away from the first vent 12, and both ends of the receiving groove 24 are connected to the second vent 21 and the outside, respectively. When the first vent 12 and the second vent 21 at least partially overlap, so that the venting channel 11 is connected to the outside, the receiving groove 24 can guide and initially collect the air fluid, guiding the air fluid through the second vent 21 and the first vent 12, reducing the turbulence or noise of the air fluid.
[0046] On the other hand, this embodiment also provides a filter mouthpiece, including a mouthpiece head and the aforementioned mouthpiece cap. The mouthpiece cap can freely switch between dustproof and breathable functions, thereby ensuring the dryness and hygiene of the filter mouthpiece. The main cap 1 is detachably connected to the mouthpiece head. This detachable connection allows the user to clean the mouthpiece head and mouthpiece cap separately, preventing harmful substances from accumulating between them and hindering cleaning. Furthermore, if the mouthpiece head or mouthpiece cap is damaged, replacement is very convenient.
[0047] Furthermore, the connection between the main cap 1 and the mouthpiece can be one of the following: snap-fit connection, magnetic connection, or threaded connection. When the main cap 1 and the mouthpiece are connected by a snap-fit connection, a first snap can be provided on the inner wall of the end of the main cap 1 away from the first vent 12, and a second snap can be provided on the outer wall of the mouthpiece accordingly. The main cap 1 and the mouthpiece are connected together by the snap-fit of the first snap and the second snap. When the main cap 1 and the mouthpiece are connected by a magnetic connection, a first magnet can be provided on the end of the main cap 1 away from the first vent 12, and a second magnet can be provided at the corresponding position on the mouthpiece. The main cap 1 and the mouthpiece are connected together by the mutual attraction of the first magnet and the second magnet. The first magnet can be provided on the end face of the main cap 1 or on the inner wall near the end face, and the second magnet can be provided on the end face of the mouthpiece or on the outer wall near the end face. When the main cap 1 and the mouthpiece are connected by threads, a first thread can be provided on the inner side wall of the end of the main cap 1 away from the first vent hole 12, and a second thread can be provided on the outer side wall of the mouthpiece. The main cap 1 and the mouthpiece are connected together by the first thread and the second thread.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here.
