Description

Technical Field

[0001] This utility model relates to the field of electronic atomization technology, specifically a novel heating element structure. Background Technology

[0002] In appliances used to heat aerosol-generated products, the heating element, as the heat source, is the core component and directly affects the heating effect. Existing similar heating appliances generally employ central heating or circumferential ring heating, with circumferential ring heating becoming the mainstream due to its large heating area and high heat transfer efficiency. Common circumferential heating element structures in existing technologies typically involve sintering the heating element inside a ceramic heating tube or printing a thick heating film onto the surface of a metal heating tube. Such heating methods are affected by the heating tube substrate, resulting in poor heat conduction efficiency and slow heating speed, while also incurring drawbacks such as complex processing and high cost. Utility Model Content

[0003] The purpose of this invention is to provide a novel heating element structure that can improve heating effect and simplify production process, thereby solving the problems of poor heat conduction efficiency, slow heating speed and complex structure of existing products.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel heating element structure, comprising a heating tube and a heating element, wherein the outer wall of the heating tube is provided with a receiving cavity, the heating element has a heating part and a lead part, the heating part is disposed in the receiving cavity, the lead part extends out of the receiving cavity, the receiving cavity is filled with a thermally conductive and insulating material, and the heating element adopts an independent control scheme.

[0005] In some embodiments, there are two or more receiving cavities, which are distributed along the circumferential outer wall of the heating tube.

[0006] In some embodiments, the receiving cavities are staggered on the outer wall of the heating tube.

[0007] In some embodiments, the number of heating elements matches the number of receiving cavities.

[0008] In some embodiments, the surface of the heating tube is provided with grooves, which are located on both sides of one of the receiving cavities.

[0009] In some embodiments, the groove is a double L structure arranged in a mirror-symmetric manner.

[0010] In some embodiments, a slot is provided at the top of the receiving cavity, one end of the lead wire extends out of the top of the receiving cavity through the slot, a limiting hole is provided at the bottom of the receiving cavity, and the other end of the lead wire extends out of the bottom of the receiving cavity through the limiting hole.

[0011] In some embodiments, the lead portion is made of a low-resistance material.

[0012] In some embodiments, the heating element is a spiral structure, a flat wound structure, or an etched mesh structure.

[0013] In some embodiments, the lower end face of the heating tube is provided with a positioning groove so as to cooperate with the support member that fixes the heating tube to define the direction during installation.

[0014] In some embodiments, the heating tube is made of metal and has an insulating coating on its surface.

[0015] Due to the adoption of the above structure, the beneficial effects of this utility model compared with the prior art are as follows:

[0016] 1. This utility model adds a receiving cavity to the outer wall of the heating tube, and embeds and solidifies the heating part of the heating element in the receiving cavity. Compared with the traditional product method of sintering the heating element inside the heating tube or printing the heating thick film on the surface of the heating tube, this optimizes the product structure and simplifies the manufacturing process, so that this utility model has the advantages of simple structure and convenient assembly.

[0017] 2. This utility model effectively reduces the impact of the heating tube substrate on the heating efficiency by setting multiple receiving cavities on the outer wall of the heating tube and embedding the heating element in each receiving cavity, thereby improving the heat conduction efficiency and enhancing the heating effect.

[0018] 3. By opening grooves on both sides of one of the receiving cavities, the heat conduction between multiple heating elements can be cut, so that the heat generated by each heating element is independent. This allows for separate control of each heating zone around the heating tube, improving the flexibility of use.

[0019] 4. The present invention uses a heating element with a spiral winding structure, which can increase the heating area and accelerate the heating speed.

[0020] 5. The lead wire of the heating element of this utility model is made of a low-resistance material, which can avoid the damage to the equipment caused by excessively high temperature at the lead wire end. Attached Figure Description

[0028] 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.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0030] Please see Figure 1-5 As shown, a novel heating element structure of this embodiment includes a hollow cylindrical heating tube 1 and a heating element 2. The heating tube 1 is made of metal and has an insulating coating on its surface. The outer wall of the heating tube 1 is provided with a receiving cavity 3. The heating element 2 has a heating part 21 and a lead wire part 22. The heating part 21 and the lead wire part 22 are connected together by welding. The heating part 22 is installed in the receiving cavity 3. The receiving cavity 3 is filled with a highly thermally conductive insulating material to improve heat transfer efficiency.

[0031] In this embodiment, there are two receiving cavities 3, which are respectively disposed on both sides of the outer wall of the heating tube 1. Each receiving cavity 3 is equipped with a heating element 2. The two receiving cavities 3 are staggered on the outer wall of the heating tube 1, one high and one low, so as to achieve staggered heating and increase the heating area of ​​the element to be heated.

[0032] It is understood that the accommodating cavity 3 of this utility model can be set to two or more, the number of heating elements 2 is matched with the number of accommodating cavities 3, and each accommodating cavity 3 can be staggered on the outer wall of the heating tube to facilitate more uniform and faster heating of the element to be heated.

[0033] To ensure the heating element 2 is stably and reliably mounted on the receiving cavity 3, a slot 5 is provided at the top of the receiving cavity 3 in this embodiment. The slot 5 is used to fix one end of the lead wire 22 of the heating element 2, which extends out of the top of the receiving cavity 3 through the slot 5. A limiting hole 6 is provided at the bottom of the receiving cavity 3. The limiting hole 6 is used to limit the other end of the lead wire 22 of the heating element 2, which extends out of the bottom of the receiving cavity 3 through the limiting hole 6. The slot 5 and the limiting hole 6 ensure the consistency of the heating element assembly, making the product structure more compact and the connection between the components more stable, thereby improving the product quality.

[0034] Furthermore, in this embodiment, the heating tube 1 has grooves 4 on its surface, located on both sides of one of the receiving cavities 3. The function of the grooves 4 is to separate the heat generated by the heating element 22 in the receiving cavity with grooves on both sides from the heat generated by other heating elements, cutting off the heat conduction between the two heating elements, thereby making the heating zones of the two receiving cavities 3 independent of each other, facilitating separate control of the two heating zones. For example, in use, the heating element with grooves on both sides can be activated first to generate heat and preheat the object to be heated, and then the heating element on the other side can be activated to generate heat, thereby providing different heating effects to the two sides of the object to be heated. In this embodiment, the grooves 4 are set as a mirror-symmetrical double-L structure with a large opening at the bottom, which can increase the isolation area and reduce the heat transfer area of ​​the heating zone, thereby improving the heat conduction efficiency of the object to be heated. It is understood that the shape of the grooves 4 includes, but is not limited to, double-L, and can also be I-shaped, O-shaped, or other shapes.

[0035] Furthermore, the lower end face of the heating tube 1 in this embodiment is provided with a positioning groove 7 so as to cooperate with the support member that fixes the heating tube 1 to define the direction during installation.

[0036] Preferably, the heating element 22 in this embodiment adopts a spiral winding structure, which can increase the heating area and make the temperature rise faster. It is understood that the present invention can also adopt a flat winding structure heating element or an etched mesh structure heating element, both of which can achieve the purpose of the present invention.

[0037] Preferably, the lead wire 22 is made of a low-resistance material (such as silver wire, silver-plated copper, etc.) to reduce the heating temperature of the lead wire 22 itself when energized, and avoid damage to the structural components or overheating of the device surface due to excessive temperature.

[0038] By adopting the above structure, the heating element 2 can be detached from the heating tube and installed independently with the receiving cavity 3 during assembly. This reduces the impact of the heating tube substrate on the heating efficiency and enables simple and quick assembly of the heating element without the need for sintering, printing, or other processes. This simplifies the production process, saves production costs, and helps improve product competitiveness.
