Abstract
Description
Technical Field
[0001] This utility model relates to the field of atomizing device technology, and in particular to an atomizing core, atomizer, and electronic atomizing device. Background Technology
[0002] In the current application of atomization device technology, the atomizing core, as a key component, directly determines the quality of atomization, significantly impacting the user experience and functionality of various products. In actual use, the atomizing core is constructed by combining a liquid-conducting substrate and a heating wire, with a solvent-containing reservoir structure then covering the substrate. Based on the principle of diffusion, the solvent diffuses from areas of high concentration to areas of low concentration. As heat is transferred, the solvent's temperature gradually rises, changing from a liquid to a gaseous state, thus releasing the various components of the solvent into the air in the form of atomization.
[0003] However, in practical applications, existing atomizing cores often suffer from poor solvent delivery due to unreasonable liquid-conducting structure design of the liquid-conducting substrate. This prevents the solvent from being delivered to the heating area in a timely and uniform manner, which in turn affects the continuity and stability of atomization. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide an atomizing core that, by opening capillary grooves on the outer wall of the atomizing substrate, can quickly draw liquid into the atomizing substrate through the capillary phenomenon of the capillary grooves and distribute it evenly, providing a sufficient liquid supply for the atomization process and greatly improving the continuity and stability of atomization.

[0034] Please see Figure 1-6This application provides an atomizing core, including an atomizing substrate 10 and a heating component 20. The atomizing substrate 10 has a hollow atomizing cavity 11, and its outer wall surface has capillary grooves 12. The heating component 20 includes a heating element 21 and a support member 22. The heating element 21 is fixed in the atomizing cavity 11, and one end of the support member 22 is fixed to the heating element 21, while the other end is exposed outside the atomizing substrate 10 and electrically connected to an external device.
[0035] It is understood that the atomizing substrate 10 is a porous ceramic structure with a porosity of 50-70%. The aerosol matrix disposed on the outside of the atomizing substrate 10 is transported to the inside of the atomizing substrate 10 through this porous structure. Heated by the heating element 21, the aerosol matrix changes from a liquid to a gaseous state, thus achieving atomization. In this embodiment, capillary grooves 12 are provided on the outer wall of the atomizing substrate 10, thereby enhancing the aerosol matrix transport capacity through the capillary phenomenon generated by the capillary grooves 12. When the liquid aerosol matrix comes into contact with the surface with the capillary grooves 12, the presence of the capillary grooves 12 increases the contact area between the aerosol matrix and the surface of the atomizing substrate 10 without increasing the volume and size of the atomizing substrate 10, thereby enhancing adhesion. Based on capillary action, the aerosol matrix flows within the capillary groove 12 due to adhesion exceeding cohesion. The capillary groove 12 then connects with the porous structure of the atomizing substrate 10. Through the interaction between the capillary groove 12 and the porous structure, the aerosol matrix further diffuses into the atomizing substrate 10, resulting in a more uniform distribution of the aerosol matrix within the atomizing substrate 10. Simultaneously, because the structure of the capillary groove 12 has more open pores than the porous structure, the resistance to liquid movement within the groove is relatively small, allowing for faster flow along the capillary groove 12. This enables the liquid to be guided more quickly from the outside of the atomizing substrate 10 to the vicinity of the heating element 21, providing a sufficient supply of aerosol matrix for the atomization process. This ensures sufficient aerosol matrix around the heating element 21 and that the aerosol matrix is uniformly heated, thereby improving the stability and consistency of the atomization effect.
[0036] Furthermore, in some embodiments, the capillary groove 12 is a linear groove disposed along the outer wall of the atomizing substrate 10. Specifically, the capillary groove 12 can be a longitudinal or transverse straight groove arranged in an array along the outer wall of the atomizing substrate 10. Alternatively, the capillary groove 12 can also be a spiral linear groove disposed along the outer wall of the atomizing substrate 10; the capillary groove 12 can also be a wavy or other curved groove, which will not be described in detail here.
[0037] Please see Figure 1 and Figure 2Preferably, in this embodiment, the atomizing substrate 10 is cylindrical, and the capillary groove 12 is a longitudinal groove arranged along the demolding direction of the atomizing substrate 10. This simplifies the mold structure and facilitates processing and forming. It can be understood that when the opening and closing direction of the forming mold of the atomizing substrate 10 is radial, the capillary groove 12 can be an annular groove along the circumferential direction.
[0038] In some other embodiments, the capillary groove 12 may also be a mesh groove provided along the outer wall of the atomizing substrate 10. Specifically, the mesh shape and mesh density can be adjusted according to the specific configuration of the heating element 10 and the atomizing cabinet 10 to achieve the effect of accelerating the flow rate of the aerosol matrix.
[0039] It should be noted that the above are only partial examples of the capillary groove 12 and do not constitute a limitation on its structure. In some other embodiments, the atomizing substrate 10 may be in the shape of a square body, a semi-cylindrical body, a sphere, etc., and the specific arrangement of the capillary groove 12 can be set according to the actual shape of the atomizing substrate 10.
[0040] Furthermore, in some embodiments, the inner wall of the capillary groove 12 is arc-shaped, which facilitates the flow of the aerosol matrix within the capillary groove 12. Specifically, the width of the capillary groove 12 is less than 1 mm, and its depth is less than 1 mm. This allows the aerosol matrix to generate capillary action under a relatively small driving force, thereby allowing the aerosol matrix to enter from the outer wall of the atomizing substrate 10 into the interior, be evenly distributed within the atomizing substrate 10, and then be transported to the vicinity of the heating element 21, providing a continuous supply of aerosol matrix for the atomization process.
[0041] Furthermore, the grooved surface area of the capillary groove 12 is 10-30% of the outer wall surface area of the atomizing substrate 10. Under this coverage area, good capillary phenomenon can be maintained and the processing and forming of the atomizing substrate 10 is not affected. In addition, no defects such as sintering deformation or cracking will occur after long-term heating and use.
[0042] Please see Figure 3-6 Furthermore, in some embodiments, the heating element 21 is spaced a certain distance from the inner wall of the atomizing cavity 11; and the shape of the heating element 21 is adapted to the shape along the inner wall of the atomizing cavity 11, that is, the heating element 21 extends along the inner wall of the atomizing cavity 11, thereby ensuring a uniform gap between the heating element 21 and the inner wall of the atomizing cavity 11. Preferably, the distance between the heating element 21 and the inner wall of the atomizing cavity 11 is 60-100 μm. In this embodiment, the atomizing cavity 11 is a circular cylindrical cavity with at least one open end, and the heating element 21 is arc-shaped with a curvature of 160°-180°, which is more conducive to the processing and shaping of the atomizing core. Preferably, the curvature of the heating element 21 is 175°-180°.
[0043] In this embodiment, a volatile coating is provided on the outer surface of the heating element 21. During the molding process of the atomizing substrate 10, this volatile coating evaporates upon heating, creating a certain gap between the heating element 21 and the inner wall of the atomizing cavity 11. This avoids carbon buildup and core clogging caused by uneven heating, and also prevents sintering deformation or cracking of the atomizing substrate 10. Furthermore, by using a heat-volatile coating to create the gap, the mold structure and manufacturing steps can be simplified, improving the production efficiency of the atomizing core. Specifically, the volatile coating is formed by applying a mixture of ethyl acetate, ethylene glycol, ethanol, acetone, titanium dioxide, and sodium oxide.
[0044] Furthermore, the heating element 21 is a hollow mesh structure carved from a metal plate. Specifically, the mesh shape of the heating element 21 can be polygonal, circular, etc. In addition, the mesh density of the heating element 21 can be adjusted according to the heat generation of the heating element 21 to achieve uniform heating. It is understood that the heating element 21 can be a heating resistor material made of nickel-chromium alloy, tungsten-molybdenum alloy, silver-palladium alloy, nickel-copper alloy, iron-chromium-aluminum alloy, or iron-chromium-aluminum-molybdenum alloy, which will not be described in detail here.
[0045] Furthermore, in some embodiments, the support member 22 includes two pins, one end of which is connected to the arc end of the heating element 21, and the other end is electrically connected to an external electrical appliance to provide current to the heating element 21 to generate heat. The support member 22 extends with a fixing portion 221 in a direction away from the heating element 21. The fixing portion 221 is embedded in the side wall of the atomizing substrate 10 to fix the heating element 21 in the atomizing cavity 11.
[0046] Specifically, the fixing part 221 is a barbed structure integrally formed with the support member 22, which can effectively prevent the support member 22 from coming out of the atomizing substrate 10.
[0047] Please see Figure 1-6 This application embodiment also provides an atomizer, including an atomizing core and a liquid storage layer. The liquid storage layer covers the outside of the atomizing core and is in contact with the outer wall of the atomizing substrate 10. The aerosol matrix in the liquid storage layer is introduced into the interior of the atomizing substrate 10 through the capillary action of the capillary grooves 12 on the outer wall of the atomizing substrate 10, and gradually flows towards the heating element 21. It is heated by the heating element 21 and becomes gaseous, thereby realizing the atomization function.
[0048] This application also provides an electronic atomizing device, including the above-mentioned atomizer, which can achieve stable and efficient atomization effect.
[0049] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows:
[0050] (1) By opening capillary grooves on the outer wall of the atomizing substrate, the capillary phenomenon of the capillary grooves can quickly draw the liquid into the atomizing substrate and make it evenly distributed, providing sufficient liquid supply for the atomization process, which greatly improves the continuity and stability of atomization.
[0051] (2) By setting a certain distance between the heating element and the inner wall of the atomizing chamber, carbon deposits and core smearing caused by uneven heating can be avoided, as well as sintering deformation or cracking of the atomizing substrate can be avoided.
[0052] (3) By setting a volatile coating on the surface of the heating element, the volatile coating is heated and volatilized during the atomization substrate forming process to form a gap between the heating element and the inner wall of the atomization cavity, thereby simplifying the mold structure and manufacturing steps and improving production efficiency.
[0053] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
