[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0036] like Figures 1 to 6 As shown, according to the first aspect of the present application, a heating device 1 is provided, which includes: a bracket 20, having a first accommodating chamber 21; a heating element 30, at least partially arranged in the first accommodating chamber 21, the heating element 30 having a second accommodating chamber 31, the second accommodating chamber 31 being used to accommodate the material to be atomized, and the heating element 30 being used to heat the material to be atomized in the second accommodating chamber 31; an elastic element 40, arranged between the heating element 30 and the bracket 20, one end of the elastic element 40 abuts against the inner wall of the first accommodating chamber 21), and the other end of the elastic element 40 abuts against the outer wall of the heating element 30, and the elastic element 40 is used to apply a compressive force to the outer wall of the heating element 30.

[0037] In the heating device 1 of the embodiment of the present application, the heating device 1 includes a bracket 20 having a first accommodating chamber 21; a heating element 30, which is inserted into the first accommodating chamber 21 and has a second accommodating chamber 31, and the second accommodating chamber 31 is used to accommodate the material to be atomized; an elastic element 40, which is arranged between the heating element 30 and the bracket 20, with one end of the elastic element 40 abutting against the inner wall of the accommodating chamber, and the other end of the elastic element 40 abutting against the outer wall of the heating element 30, and the elastic element 40 is used to apply a compressive force to the outer wall of the heating element 30. Through the above technical solution, when the material to be atomized is fully inserted into the second accommodating chamber 31 of the heating element 30, the elastic element 40 applies a compressive force to the outer wall of the heating element 30, and the compressive force can cause the inner wall of the heating element 30 to deform toward the material to be atomized, so as to ensure that the heating element 30 is in close contact with the material to be atomized, thereby improving the heat conduction efficiency, so as to improve the heating efficiency of the heating tube to the material to be atomized.

[0038] Optionally, the side wall of the heating element 30 has an opening 32 extending from one end of the heating element 30 toward the other end of the heating element 30. This arrangement can at least partially divide the heating element 30 into two structures, and then use the elastic member 40 to apply a compressive force to the side wall of the heating element 30, thereby facilitating deformation of the side wall of the heating element 30 to improve the clamping and fixing effect of the atomized material.

[0039] Optionally, the opening 32 extends along the axial direction of the heating element 30. This ensures the overall stability of the heating element 30 and, by increasing the thickness or number of layers of material along the axial direction, significantly improves the structure's compressive and tensile strength, thereby enhancing the stability of the structure. At the same time, it allows stress to be more evenly distributed throughout the heating element 30. This helps reduce stress concentration, avoids damage to local areas due to excessive stress, and helps extend the service life of the heating element 30. The uniform stress distribution also helps improve the overall load-bearing capacity of the structure. At the same time, due to the enhanced integrity and stability of the structure, it may also reduce the cost of repair and replacement due to structural damage.

[0040] Optionally, the heating device 1 has two elastic members 40, and the heating member 30 has two openings 32. The two openings 32 are symmetrically arranged along the axis of the heating member 30 to divide the end of the heating member 30 close to the elastic member 40 into two first clamping parts 33. The elastic member 40 and the first clamping part 33 are arranged in a one-to-one correspondence. In the present application, after the alternating current is passed through the winding layer 10, an alternating magnetic field is generated inside it, thereby inducing an eddy current effect inside the heating member 30. This eddy current effect causes the atoms inside the heating member 30 to collide violently, thereby achieving heating of the heating member 30. In this design, there is no specific restriction on the number of turns, wire diameter, size and shape of the winding layer 10. The bracket 20 is used to fix the winding layer 10, and is usually made of high-temperature resistant plastic material, and there is no specific restriction on the material selection. The heating member 30 uses 430 stainless steel as the main material, but other metal materials are also supported as substitutes. The heating member 30 adopts a through-body connection method at the insertion part of the atomized material to ensure smooth insertion of the atomized material. When the object to be atomized is completely inserted into the heating element 30 , the spring device applies pressure to the wall of the heating element 30 to ensure that the heating element 30 and the object to be atomized are in close contact, thereby improving the heat conduction efficiency.

[0041] Under normal environmental conditions, such as dry, non-acidic environments, 430 stainless steel exhibits excellent corrosion resistance. It effectively resists the erosion of most organic acids, organic compounds, and moisture, ensuring the long-term stability and service life of the heating element 30. Furthermore, compared to some other stainless steels, 430 stainless steel has higher hardness and strength, making it less susceptible to deformation.

[0042] Furthermore, 430 stainless steel is a magnetic material, and this property gives it a unique advantage in situations where a magnetic response is required. For example, when manufacturing components that require magnetic adsorption or magnetic induction, 430 stainless steel is an ideal choice. Furthermore, the manufacturing cost of 430 stainless steel is relatively low, which makes it competitive in application areas with high cost control requirements, thus facilitating the mass production of the heating element 30. At the same time, 430 stainless steel has good processing and forming properties, and can be processed and formed through a variety of processes such as stamping, bending, and cutting, which helps to reduce the processing difficulty and cost in the production process and improve production efficiency.

[0043] Optionally, two elastic members 40 are symmetrically arranged in the first accommodating cavity 21. This arrangement can balance the force applied to the first clamping portion 33, thereby further improving the fixing force on the atomized material.

[0044] Optionally, the heating element 30 has four elastic members 40, and the heating element 30 has two openings 32. The two openings 32 are arranged along the axis of the heating element 30 to penetrate the heating element 30 so as to divide the heating element 30 into two second clamping portions 34 spaced apart from each other. Each second clamping portion 34 corresponds to two elastic members 40, and the two elastic members 40 corresponding to one second clamping portion 34 are arranged spaced apart along the axial direction of the heating element 30. The functions of the winding layer 10 and the bracket 20 are the same as those in the above-mentioned embodiment, so they are not repeated here. The heating element 30 in this embodiment is designed as two independent left and right parts, the upper half and the lower half of which are fixed by the elastic member 40. Before the atomized object is not inserted, the elastic member 40 is in a first deformation state, which facilitates the insertion of the atomized object from the inlet 35. Once the atomized material is inserted into the heating tube, the elastic member 40 enters its second deformation state. At this point, the upper and lower sets of elastic members 40 simultaneously apply pressure to the interior of the heating element 30, ensuring a tight fit between the entire heating tube and the atomized material, significantly improving heat transfer efficiency. Furthermore, this design can accommodate atomized materials of varying sizes, achieving a snug fit.

[0045] Optionally, one end of the heating element 30 is provided with an inlet 35 communicating with the second accommodating chamber 31. The inlet 35 allows the atomized material to be inserted into the second accommodating chamber 31. The inlet 35 has a circular cross-section along the radial direction of the heating element 30, and the inner diameter of the inlet 35 is D1, where 6.6 mm ≤ D1 ≤ 7.1 mm. This configuration not only facilitates the processing of the heating element 30 but also facilitates the insertion of the atomized material into the second accommodating chamber 31, thereby meeting user requirements.

[0046] Optionally, when the atomized material is inserted into the second accommodating chamber 31, the elastic member 40 applies a compressive force to the outer wall of the heating element 30, causing the side wall of the heating element 30 to deform. The deformation of the side wall of the heating element 30 is L1, and 0.1mm≤L1≤0.5mm. This configuration can both clamp the atomized material and prevent damage to the outer wall of the heating element 30, thereby ensuring safety during use and extending the service life of the heating device 1.

[0047] Optionally, the outer wall of the bracket 20 has a plurality of receiving portions 22, which are arranged at intervals along the axial direction of the bracket 20. The winding layer 10 is wound on the outer wall of the bracket 20 along the gap between two adjacent receiving portions 22. The receiving portions 22 are used to receive at least part of the winding layer 10. This can not only ensure the regularity of the winding layer 10, but also make the spacing between adjacent winding layers 10 smaller, making the arrangement more compact, thereby improving the coupling effect.

[0048] Optionally, the bracket 20 is made of insulating and heat-insulating materials. PPS (polyphenylene sulfide) plastic can be used for the bracket 20. Due to its extremely high heat resistance, PPS plastic can withstand continuous use temperatures up to 220°C and short-term temperatures up to 260°C, making it one of the highest-temperature thermoplastic engineering plastics currently available. This allows PPS plastic to maintain excellent mechanical and insulating properties even in high-temperature environments, making it ideal for use in brackets 20 requiring high-temperature resistance. PPS plastic also has a very low molding shrinkage (less than 0.25%), extremely low water absorption (less than 0.02%), and a low linear thermal expansion coefficient. It can maintain good dimensional stability even under high-temperature conditions. Furthermore, the electrical properties of PPS material, especially its high-frequency electrical properties, are unmatched by other materials. Its dielectric constant is very low, its dielectric loss is quite low, and its surface and volume resistivities are insensitive to changes in frequency, temperature, and humidity, resulting in stable insulation strength.

[0049] Optionally, the heating device 1 further includes a winding layer 10 , which is wound on the bracket 20 along the circumference of the bracket 20 .

[0050] Optionally, the winding layer 10 includes a coil. The coil is a multi-ring coil formed by winding, and the coil and the heating element 30 can cooperate with each other to achieve electromagnetic induction heating.

[0051] Optionally, the elastic member 40 includes a spring. The above structure is simple and easy to process, thus reducing the implementation cost of the device.

[0052] According to a second aspect of the present application, an atomizer is provided, comprising the above-mentioned heating device 1 .

[0053] In the heating device 1 of the embodiment of the present application, the heating device 1 includes: a winding layer 10, a bracket 20, having a first accommodating cavity 21, and the winding layer 10 is wound on the bracket 20 along the circumference of the bracket 20; a heating element 30, which is inserted into the first accommodating cavity 21, and the heating element 30 has a second accommodating cavity 31, and the second accommodating cavity 31 is used to accommodate the material to be atomized; an elastic element 40, which is arranged between the heating element 30 and the bracket 20, one end of the elastic element 40 abuts against the inner wall of the accommodating cavity, and the other end of the elastic element 40 abuts against the outer wall of the heating element 30, and the elastic element 40 is used to apply a compressive force to the outer wall of the heating element 30. Through the above technical solution, when the object to be atomized is fully inserted into the second accommodating cavity 31 of the heating element 30, the elastic element 40 applies a compressing force to the outer wall of the heating element 30. The compressing force can cause the inner wall of the heating element 30 to deform toward the object to be atomized to ensure that the heating element 30 fits tightly with the object to be atomized, thereby improving the heat conduction efficiency and improving the heating efficiency of the heating tube on the object to be atomized.
