Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aerosol generating devices, and in particular to an antibacterial and degreasing stainless steel core heater and an aerosol generating device. Background Technology
[0002] Currently, in the heaters of aerosol generating devices, the methods for heating loosely tubular solid materials (tobacco, tea leaves, herbs, etc.) include core heating and circumferential heating. Circumferential heating has a larger heating area and more uniform temperature, but the preheating time is longer and the smoke output is slower. Core heating has uneven heating but a faster smoke output, resulting in a shorter waiting time and a better smoking experience.
[0003] Currently popular core heater solutions include: 1. Ceramic heating needles or ceramic heating elements, which have a low thermal conductivity, are prone to breakage, lack antibacterial function and are easy to breed bacteria, and are easy to accumulate oil and are difficult to clean; 2. Electromagnetic induction heating metal sheets embedded in the cigarette stick, which have a high thermal conductivity, heat up quickly, and are not prone to breakage, but the metal releases an odor at high temperatures, affecting the smoking experience; 3. Quartz heating needles: have a low thermal conductivity, are odorless and have a good smoking experience, but are prone to breakage.
[0004] The current core heater has defects such as being prone to breakage, easy to breed bacteria, having an odor, and being easy to accumulate oil and difficult to clean.
[0005] Therefore, existing technologies need to be improved. Utility Model Content
[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a stainless steel core heater with antibacterial and degreasing properties, which makes the heater less prone to breakage, avoids odors, and can inhibit bacteria and decompose accumulated oil, making it easy to clean.
[0007] To achieve the above objectives, the present invention adopts the following technical solution:
[0008] An antibacterial and degreasing stainless steel core heater includes a hollow stainless steel heating rod and a heating element disposed inside the stainless steel heating rod. The heating element is connected to an electrode. The top of the stainless steel heating rod is closed, and the bottom of the stainless steel heating rod has an opening.
[0009] The outer surface of the stainless steel heating rod is provided with a coating layer that has antibacterial and tar decomposition functions.
[0010] In some embodiments, the coating layer includes antibacterial materials and tar-decomposing materials.
[0011] In some embodiments, the antibacterial material includes silver ions, and the tar-decomposing material includes titanium dioxide.
[0012] In some embodiments, the coating layer is a plating layer or a coating layer.
[0013] In some embodiments, the top end of the stainless steel heating rod is provided with a needle tip that closes the end.
[0014] In some embodiments, the inner wall of the stainless steel heating rod and the heating element are filled with an insulating thermally conductive material.
[0015] In some embodiments, the heating element is a heating wire.
[0016] In some embodiments, the antibacterial and degreasing stainless steel core heater further includes a heat-resistant base, wherein the heat-resistant base has a mounting hole in the middle for inserting and fixing the stainless steel heating rod.
[0017] In some embodiments, the heat-resistant base has a stepped hole at the upper part of the mounting hole for placing absorbent cotton;
[0018] An abutment block is provided inside the lower part of the mounting hole wall, and the upper end of the abutment block abuts against the bottom end of the stainless steel heating rod.
[0019] This invention also proposes an aerosol generating device, which includes the aforementioned antibacterial and degreasing stainless steel core heater.
[0020] It should be understood that, within the scope of this utility model, the above-mentioned technical features of this utility model and the technical features specifically described below (such as embodiments) can be combined with each other to form new or preferred technical solutions. Due to space limitations, they will not be described in detail here.
[0021] Compared with the prior art, the beneficial effects of this utility model are:
[0022] 1. Because stainless steel is used as the heating rod, it is less prone to breakage compared to the ceramic material used in existing technologies.
[0023] 2. Because the stainless steel heating rod is coated with a film layer that has antibacterial and tar decomposition functions, the tar deposited on the outer surface of the heating rod can be catalytically decomposed during the heating of materials such as tobacco, reducing oil accumulation. At the same time, the antibacterial function of the film layer can also inhibit the growth of bacteria on the outer surface of the heating rod, thereby reducing the accumulation of dirt and realizing the self-cleaning of the heater during use, while also facilitating the cleaning of the heater after use.
[0024] 3. Due to the coating layer, the odor generated by the stainless steel material during heating is isolated by the coating layer, thus avoiding affecting the taste during use. Attached Figure Description

Detailed Implementation
[0034] 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.
[0035] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0036] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a quick-release connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0037] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0038] This utility model includes the following embodiments. For example... Figures 1 to 4 As shown, this utility model provides an antibacterial and degreasing stainless steel core heater 100, including a hollow stainless steel heating rod 10 and a heating element 20 disposed within the stainless steel heating rod 10. The heating element 20 is connected to an electrode 30. The top of the stainless steel heating rod 10 is closed, and the bottom of the stainless steel heating rod 10 has an opening 11. The stainless steel heating rod 10 is made of 304 or 316 stainless steel. The stainless steel heating rod 10 can be inserted into the center of the substance being heated (tobacco, tea leaves, herbs), thus becoming a core heater.
[0039] Preferably, such as Figure 1 As shown, the top end of the stainless steel heating rod 10 in this embodiment is provided with a needle tip 12 that closes the end. This facilitates the smooth insertion of the stainless steel heating rod 10 into the material being heated, while preventing the material being heated from entering the stainless steel heating rod 10.
[0040] Preferably, such as Figure 2 As shown, the heating element 20 in this embodiment is a heating wire. The heating wire is connected to an electrode 30. When the electrode 30 is powered on, the heating wire heats up, which in turn causes the stainless steel heating rod 10 to generate heat, thereby heating the substance being heated. It can be understood that in other embodiments, the heating element 20 may also be in the form of a heating plate, a heating tube, etc.
[0041] Specifically, in this embodiment, such as Figure 2As shown, the electrode 30 includes a positive electrode 31 and a negative electrode 32, which extend from the bottom opening 11 of the stainless steel heating rod 10. The positive electrode 31 is connected to the upper end of the heating wire, and the negative electrode 32 is connected to the lower end of the heating wire. The bottom ends of both the positive electrode 31 and the negative electrode 32 extend from the bottom opening 11 of the stainless steel heating rod 10 for easy wiring.
[0042] like Figure 3 and Figure 4 As shown, in this embodiment, the outer surface of the stainless steel heating rod 10 of the heater 100 is provided with a coating layer 40 that has antibacterial and tar decomposition functions. The coating layer 40 is a functional layer that can inhibit bacteria and decompose tar, thereby reducing or preventing oil accumulation on the outer surface of the stainless steel heating rod 10, giving the heater 100 a self-cleaning function, and also facilitating cleaning after use.
[0043] In this embodiment, the coating layer 40 includes an antibacterial material and a tar-decomposing material. Specifically, the antibacterial material includes silver ions, and the tar-decomposing material includes titanium dioxide. Silver ions can play a bactericidal and bacteriostatic role, while titanium dioxide, during the high-temperature heating process of the heater 100, catalytically decomposes the tar and other oil stains on the outer surface of the stainless steel heating rod 10 under the action of light generated at high temperature, thereby reducing oil accumulation. At the same time, it can also play a bactericidal and cleaning role in the catalytic decomposition process.
[0044] The coating layer 40 of this invention is a plating layer or a coating layer. That is, the coating layer 40 of this invention is a structure formed on the outer surface of the stainless steel heating rod 10 by plating or spraying.
[0045] In one embodiment, the coating layer 40 is a plating layer. In addition to antibacterial materials and tar-decomposing materials, the coating layer 40 also includes a high-temperature resistant substrate. In this embodiment, the coating layer 40 is formed by using a high-temperature resistant slurry as the substrate, adding appropriate amounts of slurry containing silver ions and slurry containing titanium dioxide to the substrate, and then depositing it onto the outer surface of the stainless steel heating rod 10.
[0046] Preferably, such as Figures 2 to 4 As shown, the inner wall of the stainless steel heating rod 10 and the heating element 20 are filled with an insulating thermally conductive material 50. The thermally conductive material 50 allows the heat generated by the heating element 20 to be quickly conducted to the stainless steel heating rod 10, thereby increasing the heating speed of the entire heater 100. The thermally conductive material 50 can be made of materials such as magnesium oxide or aluminum nitride. Furthermore, in this embodiment, the needle tip 12 at the top of the stainless steel heating rod 10 is also filled with thermally conductive material 50, so that the needle tip 12 can also heat up quickly.
[0047] Preferably, such as Figure 2 and Figure 3As shown, the antibacterial and degreasing stainless steel core heater 100 of this embodiment also includes a heat-resistant base 60. The heat-resistant base 60 has a mounting hole 61 in the center for inserting and fixing the stainless steel heating rod 10. The heat-resistant base 60 is used to install the entire heater 100 into the aerosol generating device. The mounting hole 61 of the heat-resistant base 60 and the stainless steel heating rod 10 can be installed with a tight fit. Preferably, in this embodiment, after the stainless steel heating rod 10 is inserted into the mounting hole 61 of the heat-resistant base 60, it is then sealed and fixed with high-temperature potting compound to ensure a strong connection between the stainless steel heating rod 10 and the heat-resistant base 60.
[0048] like Figure 5 and Figure 6 As shown, the heat-resistant base 60 has a stepped hole 62 above the mounting hole 61 for placing absorbent cotton. During the heating process of the heater 100, the aerosol will turn into liquid after cooling and flow downward into the heat-resistant base 60. At this time, the absorbent cotton in the stepped hole 62 can absorb the liquid and prevent the liquid from leaking out from the bottom of the heat-resistant base 60.
[0049] Preferably, in this embodiment, the heat-resistant base 60 has an abutment block 63 inside the lower part of the mounting hole 61. The upper end of the abutment block 63 abuts against the bottom end of the stainless steel heating rod 10. The abutment block 63 is a limiting structure that limits the movement of the stainless steel heating rod 10. When the bottom end of the stainless steel heating rod 10 abuts against the abutment block 63 during the downward movement of the stainless steel heating rod 10 after being inserted into the mounting hole 61 of the heat-resistant base 60, it can no longer move downward, indicating that the stainless steel heating rod 10 is installed in place.
[0050] The manufacturing process of the heater 100 in this embodiment is as follows:
[0051] 1. Stainless steel pipes are made from stainless steel strips of appropriate size and thickness by coil welding.
[0052] 2. The above-mentioned stainless steel tubing is drawn into long tubes of precise dimensions;
[0053] 3. A needle-shaped stainless steel heating rod is obtained by using a tapering mold to make one end of the tube into a needle shape and then cutting it to the required size;
[0054] 4. The needle-shaped stainless steel heating rod is sandblasted or anodized;
[0055] 5. Prepare slurries (high-temperature resistant slurry, UV photocatalytic tar decomposition slurry, silver ion antibacterial slurry);
[0056] 6. Apply the prepared slurry to the surface of the stainless steel heating rod to form a coating;
[0057] 7. Assemble the heating element, electrodes, thermally conductive materials, and heat-resistant base;
[0058] 8. The heater assembly is complete.
[0059] This utility model also proposes an aerosol generating device (not shown), which includes the aforementioned antibacterial and degreasing stainless steel core heater 100. Since this aerosol generating device includes the aforementioned antibacterial and degreasing stainless steel core heater 100, it has the functions and effects of the antibacterial and degreasing stainless steel core heater 100 of this utility model, which will not be described in detail here.
[0060] The antibacterial and degreasing stainless steel core heater 100 of this embodiment allows the user to heat cylindrical, loose solid materials such as tobacco directly to the center of the heated material. This not only reduces or isolates the odor generated by the stainless steel at high temperatures, but its coating layer 40 also inhibits bacteria on the heating rod and catalytically decomposes oil stains to reduce carbon buildup. This achieves rapid heating, resulting in instant smoke output, and also has a self-cleaning function during inhalation. Furthermore, the heater 100 itself is small in size and has a low specific heat capacity, effectively reducing its own heat consumption and ensuring efficient heat utilization. This achieves instant heating and cooling, improving heating efficiency and reducing energy consumption, thus achieving energy conservation and emission reduction.
[0061] The above description is merely an example to clearly illustrate the present utility model and is not intended to limit the patent scope of the present utility model. It is impossible to exhaustively list all the embodiments here. All equivalent structural transformations made using the content of the technical solution of the present utility model under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
