Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electrode fixing and sealing structure for electronic cigarettes. Background Technology

[0002] In commercially available e-cigarette cartridges, the electrodes are typically secured by an interference fit with the plastic parts and then riveted. This traditional method of securing the electrodes presents several risks:

[0003] First, during the production and assembly process, the riveting operation is uncertain, which may cause the electrode to deviate, thereby cracking the interference fit position of the plastic part and producing defective products.

[0004] Secondly, the interference fit between the plastic part and the electrode will be subject to compressive stress over a long period of time. Under the influence of the properties of the plastic material itself and external environmental factors (such as temperature changes and chemical corrosion), this stress poses a risk of interference-fit cracking.

[0005] Regardless of the reason, it may eventually lead to the risk of the electrodes becoming loose or even falling off completely, resulting in poor product contact or complete unusability, which seriously affects the reliability of the product and the user experience. Utility Model Content

[0006] The technical problem to be solved:

[0007] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a new type of electronic cigarette electrode fixing and sealing structure with stable structure, good sealing performance and low production risk. It aims to solve the problems of plastic part cracking and electrode loosening caused by riveting and interference fit in the prior art.

[0008] Technical solution:

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A novel electronic cigarette electrode fixing and sealing structure includes: an oil tank base (1); an electrode component (2); and a housing (3). The oil tank base (1) is disposed at the bottom of the housing (3), and an accommodating groove (11) is formed inside the oil tank base (1) for accommodating the electrode component (2). The electrode component (2) is disposed in the accommodating groove (11), with both ends protruding from the oil tank base (1) to achieve electrical connection with electronic components inside the housing (3). The core feature is that the electrode component (2) is integrally formed with the oil tank base (1) through an in-mold injection molding process. The plastic material of the oil tank base (1) flows and wraps the electrode component (2) during the injection molding process, and after cooling and solidification, it is firmly fixed in the accommodating groove (11).

[0011] As a preferred option, in order to further improve the reliability of fixing and sealing, the receiving groove (11) is also filled with glue.

[0012] As a preferred embodiment, the shape of the receiving groove (11) is adapted to the shape of the electrode (2), so as to ensure that the injection molding material can uniformly wrap the electrode (2).

[0013] As a specific embodiment, the receiving groove (11) is L-shaped, and its corners are arc-shaped.

[0014] As a preferred embodiment, this structure also includes a silicone component (4). The oil tank base (1) has an adapter groove (12) for fixing the silicone component (4). The silicone component (4) has a slot (41). When the silicone component (4) is installed in place, the exposed ends of the electrode component (2) are precisely embedded in the slot (41), which plays a further role in sealing and limiting.

[0015] As a preferred embodiment, to make the installation of the silicone part (4) more secure, a protrusion (13) is provided in the adapter groove (12). Correspondingly, a fixing seat (42) is provided at the bottom of the silicone part (4), and the bottom of the fixing seat (42) is provided with an adapter hole (421) for engaging the protrusion (13).

[0016] As a preferred embodiment, when two electrodes need to be installed in the structure, two receiving grooves (11) will be formed in the oil tank base (1), and the protrusion (13) is cleverly set between the two receiving grooves (11) to play a dual role of isolation and positioning.

[0017] As a preferred option, the electrode (2) can be a sheet-like structure. This technical solution is applicable because it is not affected by the shape and structure of the electrode through plastic flow wrapping.

[0018] As a preferred embodiment, in order to achieve quick assembly and reliable connection between the oil tank base (1) and the housing (3), the outer wall of the oil tank base (1) is provided with an annular buckle (14), and the bottom inner wall of the housing (3) is provided with an annular groove (31) that matches the annular buckle (14).

[0019] As a preferred embodiment, the portion of the electrode (2) enclosed in the receiving groove (11) has its outer surface in direct contact with the plastic material of the oil tank base (1), forming a tight bond without gaps.

[0020] Beneficial effects:

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] Improve production yield and reliability: By molding the electrode (2) and the oil tank base (1) together through in-mold injection molding, the potential problems such as cracking and misalignment that may be caused by traditional riveting process are fundamentally avoided, thereby improving the stability and production yield of the product.

[0023] Eliminating structural stress risks: This solution does not have an interference fit, so there will be no long-term compressive stress inside the plastic parts, eliminating the risk of aging and cracking of the plastic parts caused by this, and extending the service life of the product.

[0024] Excellent sealing performance: During the injection molding process, the plastic material can fill all the tiny gaps to form a perfect sealing structure, effectively preventing oil leakage. If glue or silicone parts (4) are added, the sealing performance will be further enhanced.

[0025] Wide applicability of design: Mold injection molding wraps the electrode by the flow of plastic, so there are no special requirements for the shape and structure of the electrode (2). It can be applied to various shapes and structures such as cylindrical, elliptical, square or sheet, which provides greater flexibility for product design. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0036] Please see Figures 1 to 4 This utility model provides a novel electronic cigarette electrode fixing and sealing structure, including an oil tank base (1), at least one electrode component (2), and a housing (3).

[0037] In this embodiment, the oil tank base (1) is the base of the entire structure, and it is usually made of plastic materials such as PC and PCTG. The oil tank base (1) is located at the bottom of the housing (3) and is used to seal the oil tank and fix the internal components. In order to achieve a stable connection with the housing (3), annular buckles (14) are injection molded on the outer wall of the oil tank base (1), while annular grooves (31) are correspondingly provided on the bottom inner wall of the housing (3). During assembly, the two can be quickly and reliably fastened by pressing the annular buckles (14) into the annular grooves (31).

[0038] The core of this embodiment lies in the method of fixing the electrode component (2). For example... Figure 2 and Figure 3As shown, the oil tank base (1) has a pre-designed structural area with a receiving groove (11). During the manufacturing process, the metal electrode (2) is first placed in the designated position of the injection mold, and then injection molding is performed. The high-temperature molten plastic material flows through the mold cavity, completely enclosing the middle part of the electrode (2) and filling it to form the receiving groove (11). After the plastic cools and solidifies, the electrode (2) becomes an inseparable part of the oil tank base (1), and the two are integrally formed. This method allows the outer surface of the enclosed part of the electrode (2) to directly contact the plastic material of the oil tank base (1), forming a stress-free, gapless, and firm fixation and seal. The two ends of the electrode (2) are precisely exposed from the oil tank base (1) for subsequent electrical connection with electronic components such as heating wires or control boards.

[0039] To accommodate different circuit designs, the shape of the receiving groove (11) can be varied, for example, it can be set as L-shaped, and in order to avoid stress concentration, its corners can be designed as smooth arcs. The shape of the electrode (2) can also be varied, and in this embodiment, a sheet-like electrode (2) can be used.

[0040] To further enhance the sealing effect and assembly stability, this embodiment also introduces a silicone part (4) made of elastic material. For example... Figure 3 As shown, the upper surface of the oil tank base (1) is provided with an adapter groove (12) for placing the silicone part (4). In this embodiment, two L-shaped receiving grooves (11) are provided for fixing the two electrode parts (2). A protruding post (13) is integrally injection molded in the adapter groove (12) between the two receiving grooves (11).

[0041] like Figure 4 As shown, the structure of the silicone part (4) matches the adapter groove (12). The silicone part (4) has two slots (41) corresponding to the exposed ends of the electrode part (2). A fixing seat (42) is also provided at the bottom of the silicone part (4), with adapter holes (421) on it. When the silicone part (4) is installed into the adapter groove (12), the protrusion (13) is precisely inserted into the adapter hole (421), providing precise axial and radial positioning of the silicone part (4) and preventing it from rotating or coming out. Simultaneously, the exposed ends of the electrode part (2) pass through and embed into the slot (41), utilizing the elasticity of the silicone to form a reliable seal.

[0042] In some applications where sealing and fixing requirements are extremely high, additional sealing glue can be filled at the joint between the electrode (2) and the receiving groove (11) to form a double guarantee of in-mold injection and glue fixing.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
