Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, specifically to an electromagnetic induction heating cartridge structure. Background Technology

[0002] Traditional e-cigarette cartridges typically use a heating wire structure, which requires soldering heating wire leads during production and assembly. This complicates the manufacturing process and increases the yield rate due to poor soldering, leading to increased production costs. Existing heating wire structures require additional structural components to accommodate the heating wire leads, further complicating the product structure and increasing the risk of e-liquid leakage from the leads. Meanwhile, the emerging electromagnetic induction heating structure suffers from uneven heating and low heating efficiency. Utility Model Content

[0003] The purpose of this utility model is to provide an electromagnetic induction heating cartridge structure that can solve the problems of complex structure, cumbersome assembly, low yield, high risk of oil leakage, and uneven heating of existing products. It has the advantages of simple structure, convenient assembly, good sealing effect, and high heating efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electromagnetic induction heating cartridge structure, comprising a hollow inductive heating element with several through holes on its surface; further comprising a liquid guiding component fitted onto the outer wall of the inductive heating element; further comprising a base having a first cavity and a second cavity, wherein the inductive heating element and the liquid guiding component are installed in the first cavity; and further comprising an inductive coil installed in the second cavity and wound around the outer wall of the first cavity.

[0005] Preferably, the inductive heating element is columnar, and the through holes are evenly distributed on the upper part of the inductive heating element.

[0006] Preferably, the area where the inductor coil is wound corresponds to the area where the through hole is distributed.

[0007] Furthermore, it also includes a fixing member that cooperates with the base to fix the inductor coil.

[0008] Preferably, the liquid guiding element is made of cotton.

[0009] Furthermore, the base has outwardly protruding buckles on both sides, which are used to attach the cartridge shell.

[0010] Due to the adoption of the above structure, the beneficial effects of this utility model compared with the prior art are as follows:

[0011] 1. The electromagnetic induction heating structure of this utility model does not require welding of heating wire leads, which simplifies the production and assembly process, improves the consistency and sealing of the product structure, and reduces the risk of oil leakage.

[0012] 2. The electromagnetic induction heating structure of this invention directly winds the induction coil around the base of the heating element's outer ring, enabling more efficient heating. The heating area of ​​the inductive heating element has several micropores, forming a heating source with more uniform heat distribution. The cotton-like liquid-conducting medium evenly permeates the liquid to be atomized, allowing for more effective decomposition of the liquid into fine particles during atomization. This improves the heating efficiency of this invention and provides users with a better experience. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-2As shown, an electromagnetic induction heating cartridge structure of this embodiment includes, from the inside out, an inductive heating element 1, a liquid guiding component 2, and a base 3. The inductive heating element 1 is made of metal and has a hollow columnar structure. Several through holes 101 are formed on the surface of the inductive heating element 1, and these through holes 101 are evenly distributed on the upper part of the inductive heating element 1, giving the upper part of the inductive heating element 1 a mesh structure. The liquid guiding component 2 is made of cotton and wraps around the outer wall of the inductive heating element 1. The base 3 has a first cavity 301 and a second cavity 302. The inductive heating element 1 and the liquid guiding component 2... The liquid component 2 is installed inside the first cavity 301. The base 3 is also provided with outwardly protruding buckles 303 on both sides, which are used to connect the cartridge shell. This embodiment also includes an inductor coil 4, which is installed inside the second cavity 302 and wound around the outer wall of the first cavity 301. The area wound by the inductor coil 4 corresponds to the mesh area on the upper part of the heating element 1. This embodiment also includes a fixing member 5, which is installed at the bottom of the base 3 and is fastened to the base 3 to fix the inductor coil 4.

[0019] In this invention, during assembly, the liquid guiding component 2 is first wrapped around the outer wall of the inductive heating element 1, and then the two are installed together into the first cavity 301. Next, the inductor coil 4 is installed into the second cavity 302. Then, the fixing component 5 is installed between the base 3 and the inductor coil 4, so that the area where the inductor coil 4 is wound corresponds to the mesh area on the upper part of the heating element 1. During this assembly process, the operator does not need to set pins and corresponding components. Compared with existing technologies, this invention simplifies the product structure, reduces assembly steps, improves product consistency and sealing, and effectively saves production costs and reduces the risk of oil leakage.

[0020] The working principle of this utility model:

[0021] During use, the liquid to be atomized inside the cartridge is absorbed by the cotton liquid guide 2 and adheres to it. When the induction coil 1 is energized, an alternating magnetic flux of the same frequency is generated inside the coil. This alternating magnetic flux induces an electromotive force in the inductive heating element 1, and the magnetic lines of force within the magnetic field heat the inductive heating element 1. The outer periphery of the inductive heating element 1 is tightly attached to the cotton liquid guide 2, thus atomizing the liquid adhering to the guide 2 during heating. Compared with existing technologies, this invention, through a unique base structure design, shortens the distance between the induction coil and the inductive heating element, achieving more efficient heating. The unique mesh inductive heating element design consists of 1,600 0.1mm micropores in its heating area, forming a heating source with more uniform heat distribution. Simultaneously, the cotton liquid guide medium allows for more even penetration of the liquid to be atomized, thereby more effectively breaking down the liquid into fine particles during atomization, improving the atomization effect and providing users with a better inhalation experience.
