[0030] Electronic cigarettes are devices that convert atomized liquid into aerosols. With the development of the electronic cigarette industry, atomization technology and related materials are also constantly updated and iterated. At present, the main electronic cigarette atomization materials are cotton core and ceramic core. The application of cotton core is limited to a certain extent due to its poor oil locking ability, poor consistency and easy oil explosion.

[0031] In order to pursue the stability and fineness of taste, porous atomizer cores are often used to atomize the e-liquid. At present, the ceramic atomizer core is mainly composed of a heating component and a porous ceramic body. Most of the heating components are directly and tightly assembled with the ceramic body through an embedded method. The disadvantage is that the energy utilization rate of the heating component is low, the amount of smoke is small, and the taste explosiveness is weak, which affects the user experience.

[0032] In view of this, the present application provides an atomization module, including a porous ceramic and a heating element. Without changing the volume of the porous ceramic, a liquid storage tank is provided in the middle of the porous ceramic, and the heating element covers the outer wall of the porous ceramic, forming "oil inlet in the middle and atomization on the periphery", increasing the atomization area, reducing heat loss during operation of the heating element, improving energy utilization, and thereby improving atomization efficiency and taste burst.

[0033] See also Figure 1 to Figure 4 , the atomization module provided in this embodiment is now described. The atomization module 100 in this embodiment includes a porous ceramic 1 and a heating element 3. The porous ceramic 1 has a plurality of micropores, and the atomized matrix can flow through the micropores. A liquid reservoir 2 is provided in the middle of the porous ceramic 1, and the height of the liquid reservoir 2 is less than the height of the porous ceramic 1. It can be understood that the liquid reservoir 2 does not run through the entire porous ceramic 1, that is, one end of the liquid reservoir 2 has an opening, and the atomized matrix is ​​stored in the liquid reservoir 2. The heating element 3 is in the shape of a mesh and is attached to the outer wall of the porous ceramic 1.

[0034] In this embodiment, without changing the volume of the porous ceramic 1, a liquid storage tank 2 is provided in the middle of the porous ceramic 1, and the heating element 3 covers the outer wall of the porous ceramic 1, forming "oil inlet in the middle and atomization on the periphery", increasing the atomization area, reducing the heat loss of the heating element 3 during operation, improving energy utilization, and thereby improving the atomization efficiency and taste burst.

[0035] In one possible implementation, see Figure 1 and Figure 2 There are two heating elements 3, and the two heating elements 3 are evenly distributed around the circumference of the porous ceramic 1. The two heating elements 3 are enclosed in a "C" shape and wrapped in the porous ceramic 1, and the resistance values ​​of the two heating elements 3 are the same. When a large amount of smoke is required, the two heating elements 3 can be controlled to heat at the same time; of course, one of the heating elements 3 can also be controlled to work separately. Since the resistance values ​​of the two heating elements 3 are the same, the same voltage can be supplied to both ends of the heating element 3 when power is supplied, so that the heating power of each heating element 3 is the same, thereby ensuring that the two heating elements 3 have the same atomization effect, and the two heating elements 3 are heated alternately to extend the service life of the heating element 3, and the atomization matrix can flow to the atomization surface of the porous ceramic 1 in time to avoid dry burning and ensure the atomization effect.

[0036] Correspondingly, the heating element 3 includes a plurality of electrodes 4. Specifically, there are three electrodes 4, one of which is configured as a common electrode, which is arranged between the two heating elements 3 and electrically connected to the corresponding ends of the two heating elements 3. The remaining two electrodes 4 are respectively arranged at the other ends of the other two heating elements 3 and connected to the corresponding ends of the heating elements 3. The common electrode can be a common negative electrode of the two heating elements 3, or can be a common positive electrode of the two heating elements 3. The free ends of the three electrodes 4 are bent toward the porous ceramic 1 to form a conductive part 5, and the conductive part 5 is attached to the bottom wall of the porous ceramic 1. The power supply component can directly realize circuit conduction with the conductive part 5 through a spring ejector structure, and the structure is simple and convenient to operate.

[0037] In this embodiment, two heating elements 3 are provided on the outer peripheral side of the porous ceramic 1, and the two heating elements 3 are independent of each other, forming a "double mesh core" in combination. Compared with the "single mesh core", the atomization area is large and the smoke volume is large, which can meet the needs of high burst and large smoke volume. In addition, in order to ensure the atomization effect and avoid the problem of dry burning, the height of the liquid storage tank 2 is greater than or equal to the height of the heating element 3.

[0038] In another possible implementation, see Figure 3 and Figure 4 There are two heating elements 3, and the two heating elements 3 are spaced apart along the height direction of the porous ceramic 1, and each heating element 3 extends along the circumference of the porous ceramic 1. The two heating elements 3 are of the same size and shape, and are distributed up and down on the outer side wall of the porous ceramic 1. Correspondingly, three electrodes 4 are provided, one of which is configured as a common electrode, which extends along the height direction of the porous ceramic 1 and electrically connects the two heating sheets. The common electrode can be a common positive electrode or a common negative electrode, and the other two electrodes 4 have opposite polarities to the common electrode.

[0039] In a possible implementation, at least part of the electrode 4 is embedded in the porous ceramic 1. The electrode 4 is fixedly connected to the heating element 3 by welding and combined to form a whole, and part of the electrode 4 is buried in the porous ceramic 1 to improve the connection stability between the heating element 3 and the porous ceramic 1. In addition, the thickness of each electrode 4 is greater than the thickness of the heating element 3. On the one hand, the impedance of the electrode 4 is reduced, thereby improving the conductivity of the electrode 4. On the other hand, when part of the electrode 4 is embedded in the porous ceramic 1, it can also ensure that the electrode 4 and the heating element 3 form a smooth transition, thereby ensuring the overall aesthetics of the module.

[0040] Furthermore, one end of the porous ceramic 1 away from the port of the liquid storage tank 2 is covered with an oil-proof sealing layer (not shown), that is, the bottom of the porous ceramic 1 is provided with an oil-proof sealing layer to prevent the atomized matrix from leaking from the bottom of the porous ceramic 1 under the action of gravity.

[0041] On the other hand, the present application also provides an electronic atomizer, which includes the above-mentioned atomization module 100, and the atomization module 100 includes a porous ceramic 1 and a heating element 3. A liquid storage tank 2 is provided in the middle of the porous ceramic 1, and the heating element 3 is attached to the outer wall of the porous ceramic 1, that is, the outer wall of the porous ceramic 1 is an atomization surface, and the porous ceramic 1 has a plurality of micropores. The atomization matrix in the liquid storage tank 2 can flow from the micropores to the atomization surface, forming "oil inlet in the middle and atomization on the periphery", increasing the atomization area, reducing the heat loss of the heating element 3 during operation, improving energy utilization, and thereby improving the atomization efficiency and taste burst.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
