Description

Technical Field

[0001] This utility model relates to electronic cigarettes, specifically to an improved structure of the smoke duct of an electronic cigarette atomizer. Background Technology

[0002] Existing e-cigarette atomizers have limitations in their duct structure design. On one hand, traditional duct resistance control is not precise enough, resulting in an unsatisfactory and stable vaping experience. Excessive or insufficient resistance negatively impacts the user's experience. On the other hand, condensation easily accumulates within the duct, altering the flavor of the vapor and potentially leading to accidental inhalation, affecting safety and comfort. Furthermore, existing ducts lack effective airflow compensation structures, making it difficult to guarantee stable and consistent atomization under varying environments and conditions, thus failing to meet users' demands for high-quality e-cigarettes.

[0003] Therefore, there is an urgent need to improve the smoke duct structure of electronic cigarette atomizers in order to enhance the overall performance and user experience of electronic cigarettes. Utility Model Content

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1: The specific structure of this utility model is as follows:

[0040] Please refer to the appendix. Figure 1-8 The present invention relates to an improved flue structure for an electronic cigarette atomizer, the improved structure comprising:

[0041] An opening 21 is provided in the mouthpiece 2, which communicates with the atomizing chamber 41 of the atomizer 4 and is also connected to the smoke outlet duct of the mouthpiece 2.

[0042] A rubber plug 1 that can be flipped up and covers the oral cavity 21 is provided with a compensating airway that communicates with the oral cavity 21 and the compensating airway communicates with the external space.

[0043] The side of the mouthpiece 2 is provided with a slot 22;

[0044] The rubber stopper 1 has a stopper head and a connecting band 12 connected to the side of the stopper head, and the connecting band 12 and the insert 22 are fastened together.

[0045] Specifically, the core components of this improved structure include a mouthpiece 2 and a rubber stopper 1. The mouthpiece 2 has an opening 21, which communicates with the atomizing chamber 41 of the atomizer 4 and also connects to the smoke outlet of the mouthpiece 2, forming the main path for smoke flow. The rubber stopper 1 is flip-up and covers the opening 21. The rubber stopper 1 also has a compensation air passage that connects to the external space to achieve air intake compensation, ensuring smooth smoke discharge. Furthermore, the mouthpiece 2 has a recess 22 on its side. The rubber stopper 1 has a stopper head and a connecting strap 12 connected to the side of the stopper head. The connecting strap 12 and the recess 22 are fastened together, thus achieving a stable connection between the rubber stopper 1 and the mouthpiece 2, while ensuring that the rubber stopper 1 can be flipped flexibly.

[0046] The opening 21 has at least one notch 23 at its edge to facilitate prying up the rubber stopper 1, such as... Figure 1 As shown, there are two notches 23. The function of the notches 23 is to facilitate the entry of fingers or other objects so as to make it easier to pry up the rubber stopper 1.

[0047] The mouthpiece 2 has an arc-shaped concave surface 24 on the lower side of its smoke outlet. The purpose of designing this arc-shaped concave surface 24 is to facilitate the fit of the lower lip.

[0048] The angle between the inclined surface formed by the open end of the mouthpiece 2 and the rubber stopper 1 after it is attached to the opening 21 and the radial surface of the mouthpiece 2 is in the range of 10-25°, and preferably 17.9 degrees.

[0049] Regarding the specific structure of the compensating airway, there are multiple implementation methods, which will be described in turn through Examples 2-5 below.

[0050] Example 2:

[0051] like Figure 2-3 As shown, the following is a structural diagram of the first type of compensating airway of this utility model.

[0052] The plug has a first channel 11 that runs through both sides. After the plug is attached to the opening 21, the compensation air passage is formed between the first channel 11 and the inner wall of the opening 21.

[0053] The first channel 11 is configured with a tapering structure that is wider on the outside and narrower on the inside.

[0054] Specifically, when the plug cap is connected to the oral cavity 21, a compensating airway is formed between the first channel 11 and the inner wall of the oral cavity 21. The first channel 11 is designed with a gradually narrowing structure that is wider at the outside and narrower at the inside. This design is beneficial for guiding and buffering the incoming air, so that the air can enter the oral cavity 21 more evenly and stably, thereby ensuring the stable discharge of smoke from the atomizing chamber 41.

[0055] Example 3:

[0056] like Figure 4 As shown, Figure 4 This is a diagram of the second type of compensating airway structure of this utility model.

[0057] The plug has a second channel 111 that runs through both sides. After the plug is attached to the opening 21, the compensation air passage is formed between the second channel 111 and the inner wall of the opening 21.

[0058] The two sides of the second channel 111 are rounded and the second channel 111 is inclined.

[0059] Specifically, after the plug cap connects to the oral cavity 21, a compensating airway is formed between the second channel 111 and the inner wall of the oral cavity 21. The rounded edges on both sides of the second channel 111 can reduce airflow resistance and prevent scratches to the user; and the inclined setting of the second channel 111 can guide air to enter at a specific angle, optimize the air intake effect, and improve the smoothness of smoke discharge.

[0060] Example 4:

[0061] like Figure 5 As shown, Figure 5 This is a structural diagram of the third type of compensating airway of this utility model.

[0062] The plug has a first air hole 112 that runs through both ends in the middle. Although the smoke after the atomization chamber 41 is atomized can be discharged from the smoke outlet of the mouthpiece 2 after the air is introduced through the first air hole 112, this structure still cannot meet the user's requirements.

[0063] Specifically, the middle of the plug is provided with a first air hole 112 that runs through both ends. Although this first air hole 112 can allow air to enter and the smoke after being atomized by the atomizing chamber 41 is discharged from the smoke outlet of the mouthpiece 2, it is rarely used in practical applications because it cannot meet the user's higher requirements for air intake volume and air intake stability.

[0064] Example 5:

[0065] like Figure 6-8 As shown, Figure 6 This is a structural diagram of the fourth type of compensating airway of this utility model. Figure 7 for Figure 6 The structural diagram after removing the rubber sleeve. Figure 8 This is a structural diagram of the inclined plug of this utility model.

[0066] The plug includes:

[0067] The rubber sleeve 1131 has a through cavity extending through both ends, and one side of the rubber sleeve 1131 is beveled and the other side is flat.

[0068] The inclined plug 1132 has an inclined surface at one end and a flat surface at the other end. A rubber column is connected to the flat end. The rubber column has at least one inclined groove 1135 on its circumferential side. The inclined plug 1132 has a second air hole 113 at the inclined end. The second air hole 113 connects to each inclined groove 1135. After the inclined plug 1132 is fixed in the through cavity, an annular cavity is formed between the rubber column and the inner wall of the through cavity.

[0069] A cylindrical tube 1133 is fitted onto the adhesive column and surrounds the inclined groove 1135 on the adhesive column;

[0070] The limiting plate 1134 abuts against and defines the cylinder 1133, and has an opening to allow the inclined groove 1135 to guide the atomizing chamber 41.

[0071] Specifically, the fourth type of plug structure is more complex and refined, including a rubber sleeve 1131, a beveled plug 1132, a cylinder 1133, and a limiting plate 1134. The rubber sleeve 1131 has a through cavity extending through both ends, with one side being a bevel and the other side being a flat opening; the beveled plug 1132 has a bevel at one end and a flat end at the other, with a rubber column connected to the flat end. The circumferential side of the rubber column has at least one beveled groove 1135, and the beveled plug 1132 has a second air hole 113 at the beveled end, which connects to each beveled groove 1135. When the beveled plug 1132 is fixed in the through cavity, an annular cavity is formed between the rubber column and the inner wall of the through cavity; the cylinder 1133 is sleeved on the rubber column and surrounds the beveled groove 1135 on the rubber column; the limiting plate 1134 abuts against the cylinder 1133 and limits the cylinder 1133, and has an opening to allow the beveled groove 1135 to guide the atomizing chamber 41. In this structure, external air can enter through the second air hole 113, pass through the inclined groove 1135, the annular cavity and other structures, and finally enter the atomization chamber 41, forming an efficient and stable air intake channel, which greatly optimizes the smoke exhaust effect and meets the user's demand for a high-quality atomization experience.

[0072] In summary, during actual use, users can choose a suitable rubber stopper 1 with a suitable compensating airway structure and install it on the mouthpiece 2 according to their own needs and usage habits. When the electronic cigarette atomizer needs to be used, flip the rubber stopper 1 to open the opening 21, and air enters the atomizing chamber 41 through the compensating airway, assisting the smooth discharge of the atomized smoke from the smoke outlet of the mouthpiece 2; after use, flip the rubber stopper 1 to cover the opening 21, which protects the mouthpiece 2 and its internal structure and prevents dust and other impurities from entering.

Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
