At present, the atomizer core assembly in the atomizer is mainly composed of ceramic cores and cotton cores, and the heater is mainly composed of etched sheets (or heating wires). However, the etched sheets (or heating wires) have a simple structure and a very small contact area with the ceramic core (or cotton core). When heated, it causes local temperature differences to a large extent, which may cause the core to stick, thereby affecting the atomization effect of the electronic cigarette. In addition, the heating wire is also one of the factors that affect the taste of the electronic cigarette, but the existing heating wire cannot indirectly improve its taste by designing its own structure.

[0032] like Figures 1 to 12 As shown, an atomizer provided by the present invention includes an oil storage shell 10, an atomization chamber shell 20, and an atomization core assembly 30. The oil storage shell 10 is provided with an oil storage chamber 101 for storing tobacco oil, and the atomization chamber shell 20 is provided with an atomization chamber 201. The oil storage chamber 101 and the atomization chamber 201 are connected to each other. The atomization core assembly 30 is arranged at the connection between the oil storage chamber 101 and the atomization chamber 201. One side of the atomization core assembly 30 contacts the oil storage chamber 101, and the other side contacts the atomization chamber 201. The atomization core assembly 30 is used to atomize the tobacco oil stored in the oil storage chamber 101 and form smoke, and the smoke flows into the atomization chamber 201 from the other side of the atomization core assembly 30. The atomizer core assembly 30 includes a porous ceramic 31 and a heating mesh 32. The heating mesh 32 is bonded to the porous ceramic 31. The heating mesh 32 includes a first heating mesh 321 and a second heating mesh 322 of different mesh sizes. The edges of the first heating mesh 321 and the second heating mesh 322 are spliced together. The mesh size of the heating mesh 32 represents the number of holes within a certain area. A larger mesh size indicates a greater number of holes within a certain area and a smaller hole diameter. Conversely, a smaller mesh size indicates a larger hole diameter. After the edges of the first heating mesh 321 and the second heating mesh 322 are spliced together, they can be connected together through a welding process.

[0033] In this application, the edges of a first heating net 321 and a second heating net 322 of different mesh sizes are spliced together to form a heating net 32. The different mesh sizes of the heating net 32 result in different flavors of the atomized e-liquid, allowing the flavor of the e-cigarette to be controlled by designing the areas of the first heating net 321 and the second heating net 322. Furthermore, the use of the first heating net 321 and the second heating net 322 of different mesh sizes to form the heating net 32 ensures a stable local temperature balance, preventing the occurrence of wick burns that could affect the atomization effect of the e-cigarette.

[0034] In this embodiment, Figure 3As shown, the oil storage shell 10 is arranged in the atomizing chamber shell 20, and the oil storage shell 10 is provided with an oil filling port 102 ( Figure 9 The oil storage chamber 101 is connected to the atomization chamber 201 via the oil filling port 102. The atomization core assembly 30 is located in the atomization chamber 201 and docked with the oil filling port 102. The oil filling port 102 is located at the bottom of the oil storage housing 10, allowing the e-liquid to flow downward into the cavity of the atomization core assembly 30 under the action of gravity, and then flow to the heating network 32 and begin to atomize.

[0035] Furthermore, the atomization bin shell 20 is provided with a flue 202 communicating with the atomization bin 201 , and the flue 202 is arranged around the periphery of the oil storage shell 10 .

[0036] Specifically, if Figure 3 、 Figure 5 as well as Figure 9 As shown, the atomizer housing 20 includes a base 21 and a shell 22 connected to the base 21. An atomizer chamber 201 is formed between the base 21 and the shell 22. The shell 22 is a double-layer tubular structure, and an annular flue 202 is formed between the two layers of the tubular structure. The shell 22 is provided with a receiving hole 203 for mounting the oil storage shell 10, and the oil storage shell 10 is fixed in the receiving hole 203. The flue 202 adopts an annular airway design, and the flue 202 and the atomizer housing 20 are integrated, which can enable the atomized gas to be discharged quickly. In addition, the flue 202 is integrated with the atomizer housing 20 and is away from the heating network 32. This can reduce the temperature of the atomized gas to a certain extent, prevent the temperature of the inhaled smoke from being too high, and provide the smoker with a good taste. Of course, in other embodiments, the atomizer housing 20 can also be located within the oil storage shell 10, with the oil storage cavity 101 arranged around the periphery of the atomizer housing 20, and the flue 202 arranged in the center of the atomizer, but the speed of discharging the atomized smoke is slower.

[0037] Furthermore, the base 21 is provided with a plurality of air inlet holes 204 that are in communication with the atomization chamber 201. The plurality of air inlet holes 204 are distributed in a ring shape and are located at the bottom of the atomization core assembly 30, so that air can quickly enter the atomization chamber 201 and quickly discharge the atomized smoke.

[0038] like Figure 4 、 Figure 6 、 Figure 7 、 Figure 10 as well as Figure 11As shown, the heating network 32 is provided with a wire 323, and the base 21 is provided with an electrode column 211 electrically connected to the wire 323 and a mounting hole 205 for mounting the electrode column 211. One end of the wire 323 is conductively connected to the heating network 32, and the other end of the wire 323 is connected to the electrode column 211. The end of the electrode column 211 away from the wire 323 is exposed on the outer surface of the atomization chamber shell 20. It can be understood that the wire 323 and the electrode column 211 both include a positive electrode and a negative electrode to respectively lead the heating network 32 to the positive and negative poles of the power supply. One of the wires 323 is connected to the edge of the heating network 32, and the other wire is connected to the center of the heating network 32. Similarly, one of the electrode columns 211 is located at the center of the base 21, and the other electrode column 211 is located on the base 21 and corresponds to the wire 323 connected to the edge of the heating network 32.

[0039] In this embodiment, the shape of the porous ceramic 31 and the heating net 32 are both semi-hollow spherical structures. The heating net 32 is attached to the outer surface of the porous ceramic 31, and the edges of the first heating net 321 and the second heating net 322 are spliced together to form a semi-hollow spherical structure. By setting the shape of the porous ceramic 31 and the heating net 32 to a semi-hollow spherical structure, on the one hand, the oil filling port 102 is maximized and the oil filling speed is increased; on the other hand, the atomization contact area can be maximized, and the smoke oil can be atomized in time, with high atomization efficiency and large atomization volume. Among them, the heating net 32 (stainless steel, iron-chromium-aluminum, nickel, etc.) with a welded or brushed electrode (copper, silver) is tightly fitted to the outer surface of the hemispherical ring-shaped porous ceramic 31 and sintered into one.

[0040] In this embodiment, Figure 7 and Figure 11 As shown, the first heating net 321 and the second heating net 322 are a top-to-bottom spliced structure. For example, the first heating net 321 is the upper part of a semi-hollow sphere, and the second heating net 322 is the lower part of a semi-hollow sphere. The mesh number of the first heating net 321 is greater than the mesh number of the second heating net 322, that is, the aperture of the first heating net 321 is smaller than the aperture of the second heating net 322. The holes on the first heating net 321 and the second heating net 322 can be square holes, prismatic holes, or round holes. Of course, in other embodiments, the first heating net 321 and the second heating net 322 can also be a left-to-right spliced structure, that is, the first heating net 321 and the second heating net 322 are both quarter-hollow sphere structures.

[0041] Furthermore, if Figure 4 、 Figure 6 as well as Figure 10As shown, the atomizer core assembly 30 includes a support base 33. The support base 33 is provided with a mounting groove 331 (i.e., a hemispherical groove) that matches the porous ceramic 31 and the heating net 32, and a plurality of ventilation holes 332 that are connected to the mounting groove 331. The heating net 32 is sandwiched between the porous ceramic 31 and the support base 33. The e-liquid flows from the oil filling port 102 through the porous ceramic 31 to the heating net 32, where it is heated and atomized to form smoke. The smoke enters the atomization chamber 201 through the ventilation holes 332. The functions of the support base 33 are: first, to support the porous ceramic 31 and the heating net 32 so that the heating net 32 and the porous ceramic 31 can fit tightly together; second, the porous design is to ensure that the smoke atomized by the heating net 32 can be fully discharged.

[0042] The support base 33 is provided with a support column 333 at the bottom. The support base 33 is fixed to the base 21 via the support column 333 , so that the atomizer core assembly 30 is sandwiched between the base 21 and the bottom wall of the oil storage housing 10 .

[0043] like Figure 4 、 Figure 6 as well as Figure 10 As shown, the atomizer core assembly 30 includes a spacer layer 34, which is provided with a plurality of through holes 341. The spacer layer 34 is sandwiched between the heating net 32 and the support base 33. The spacer layer 34 is made of an insulating, heat-insulating, and high-temperature resistant material, such as silicone. The spacer layer 34 is provided between the heating net 32 and the support base 33. The purpose of providing the spacer layer 34 between the heating net 32 and the support base 33 is to allow the heating net 32 and the porous ceramic 31 to be more closely fitted together under the support of the support base 33, thereby ensuring that the heating net 32 can more fully atomize the smoke oil derived from the porous ceramic 31. In addition, the risk of burning the heating net 32 and the porous ceramic 31 due to not being tightly fitted is avoided.

[0044] like Figure 8 and Figure 12 As shown, the through hole 341 includes a plurality of elongated holes and a plurality of circular holes, wherein the plurality of elongated holes are distributed in the upper region of the spacer layer 34, and the plurality of circular holes are distributed in the lower region of the spacer layer 34, wherein the elongated holes extend from the edge of the spacer layer 34 toward the bottom center of the spacer layer 34, and the width of the elongated holes gradually narrows from the edge of the spacer layer 34 toward the bottom center of the spacer layer 34, thereby facilitating faster extraction of smoke.

[0045] Further, if Figure 4 、 Figure 6 as well as Figure 10As shown, the atomizer core assembly 30 is provided with a sealing ring 35, which is sandwiched between the atomizer core assembly 30 and the oil storage shell 10. Specifically, the sealing ring 35 is sandwiched between the periphery of the porous ceramic 31 and the bottom wall of the oil storage shell 10. The sealing ring 35 can be made of silicone, which has a certain degree of elasticity and is also insulating and heat-resistant. The sealing ring 35 not only prevents the e-liquid from leaking from the oil filling port 102 and the atomizer core assembly 30 into the atomizer chamber 201, but also allows the heating network 32 to fit more tightly with the porous ceramic 31 under the pressure between the base 21 and the bottom wall of the oil storage shell 10.

[0046] The present invention also provides an electronic cigarette comprising a mouthpiece 40 and the aforementioned atomizer, wherein the mouthpiece 40 is connected to the atomizer. The mouthpiece 40 is provided with an air intake hole 401, which is connected to a flue 202, thereby allowing smoke to be drawn out through the flue 202. The electronic cigarette also includes a battery and a control chip. The battery is used to provide power to the atomizer, and the control chip is used to control the battery to provide power to the atomizer, thereby controlling the amount of atomization produced by the atomizer.
