Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of atomization, in particular to an atomization core assembly and an electronic cigarette. Background Art
[0002] The carbon deposition problem during the atomization of e-cigarettes refers to that during the use of e-cigarettes, some residual substances will be generated from the components in the e-liquid during the heating process, and to a certain extent, they will accumulate at parts such as the heating part. These residual substances may have a negative impact on the health of users and also reduce the service life of e-cigarettes. The atomization core assembly is an important structure of an e-cigarette, which is used to generate heat to atomize the liquid. The carbon deposition problem mainly occurs on the heating part of the atomization core assembly.
[0003] Most of the existing atomization core assemblies on the market adopt a single heating part solution. Continuing to use a single heating part will quickly trigger the problem of carbon deposition. While a small number adopt a multi-heating part solution, the volume increases significantly compared to the single heating part, especially the radial length increases, resulting in an increased occupied volume. As a portable handheld device, when the occupied volume of the atomization core assembly increases, it will squeeze the space of the liquid storage device, resulting in a reduction in the e-liquid capacity. Summary of the Utility Model
[0004] In view of this, the purpose of the present utility model is to provide an atomization core assembly and an electronic cigarette, which can control the independent working conditions of multiple heating parts through multiple second conductors, thereby adjusting the atomization amount; the alternating operation of the heating parts can also increase the service life and reduce the carbon deposition problem; moreover, the layout structure of multiple conductors is reasonably designed, having the advantages of compact structure and small occupied space.

[0042] The following will be described in detail through specific embodiments.
[0043] As Figures 1 to 11 shown, an embodiment of the present utility model provides an atomization core assembly for generating heat to atomize a liquid, including a housing 100 and a heating component 200. An air flow channel 110 and a liquid guiding hole 120 penetrating through its interior are provided on the housing 100. The heating component 200 is fixedly arranged in the air flow channel 110. The liquid guiding hole 120 is used to guide the liquid to flow from the outside of the housing 100 onto the heating component 200. The heating component 200 is used to atomize the liquid and then flow out of the housing 100 from the air flow channel 110;
[0044] As Figure 8 , Figure 9 and Figure 11 shown, the heating component 200 includes a plurality of heating elements 210, a first conductor 220, and a plurality of second conductors 230. The first conductor 220 is fixedly connected to one end of the plurality of heating elements 210. The first conductor 220 is a common electrode for the plurality of heating elements 210. The plurality of second conductors 230 are respectively fixedly connected to the other ends of the plurality of heating elements 210. The second conductor 230 is the other electrode corresponding to the heating element 210;
[0045] An opening 151 is formed in the housing 100, and the first conductor 220 passes through the opening 151 and extends out of the housing 100. A plurality of second conductors 230 extend out of the housing 100 along the air flow channel 110.
[0046] In this embodiment, the atomization core assembly further includes a first liquid guide 160. The first liquid guide 160 is disposed between the heating component 200 and the liquid guide hole 120 and is used to guide the liquid onto the heating component 200. Specifically, the first liquid guide 160 is a hollow cylinder made of cotton material, which has the effect of absorbing the liquid and flowing within the first liquid guide 160. Specifically, the first liquid guide 160 is a cotton wick for guiding oil.
[0047] In this embodiment, the housing 100 includes an upper cover 130, an outer shell 140, and a lower cover 150. The upper cover 130, the lower cover 150, and the first liquid guide 160 are all hollow cylinders. The upper cover 130 and the lower cover 150 are disposed at both ends of the first liquid guide 160. The outer shell 140 is a sleeve, and the outer shell 140 is sleeved on the outer sides of the upper cover 130, the lower cover 150, and the first liquid guide 160 for fixedly connecting the upper cover 130, the lower cover 150, and the first liquid guide 160. Specifically, as Figure 8 shown, the thicknesses of the upper cover 130, the lower cover 150, and the first liquid guide 160 are approximately the same, and the three are abutted against each other to form a cylindrical structure. The upper cover 130 and the lower cover 150 are defined relative to the user. When using the electronic cigarette, the upper cover 130 faces upward and the lower cover 150 faces downward. An air outlet 131 is provided at the upper cover 130, and an air inlet 154 is provided at the lower cover 150. The user inhales from the upper cover 130, and the gas flows into the intake passage from the lower cover 150, carrying the smoke at the heating component 200 and flowing into the user's mouth from the air outlet 131. Raised steps are provided on the outer sides of the upper cover 130 and the lower cover 150 for abutting against both ends of the outer shell 140 to achieve a fixed effect. Two raised reinforcing ribs are further provided on the inner side wall of the upper cover 130 for fastening with the mouthpiece of the electronic cigarette. The mouthpiece is detachably connected to the upper cover 130, facilitating the replacement of the mouthpiece. Two protrusions are provided on the outer side of the lower cover 150 inserted into the outer shell 140, and these two protrusions are in contact with the inner side of the outer shell 140. Since the protrusions are elastic and increase the friction with the outer shell 140, the sealing performance between the outer shell 140 and the lower cover 150 can be improved, and it is convenient to disassemble the lower cover 150. The lower cover 150 is fixedly connected to the heating component 200. Therefore, removing the lower cover 150 can conveniently take out the heating component 200. In this way, when carbon deposition inevitably occurs in the heating component 200 after long-term use, the heating component 200 can be easily replaced.
[0048] In this embodiment, the liquid guide hole 120 is formed in the outer shell 140 for the liquid to flow through the liquid guide hole 120 and onto the first liquid guide 160. Specifically, as Figure 3As shown, a plurality of liquid guiding holes 120 are provided on the outer shell 140 and are distributed at equal intervals along the circumference of the outer shell 140. The plurality of liquid guiding holes 120 can ensure that the liquid uniformly penetrates into the first liquid guiding body 160 and improve the penetration speed.
[0049] In this embodiment, an air outlet 131 and an air inlet 154 are respectively provided on the upper cover 130 and the lower cover 150. The air outlet 131, the air inlet 154 and the inner cavity of the first liquid guiding body 160 are communicated to form an air flow channel 110. Specifically, as Figure 9 shown, the air outlet 131 is a regular circular opening, and the air inlet 154 is an irregular opening. This is because the second conductor 230 also needs to extend out from the air inlet 154. Therefore, the air inlet 154 needs to be designed to make way for the following plurality of second conductors 230. The cross-sectional area of the air inlet 154 is smaller than that of the air outlet 131.
[0050] As Figure 9 shown, in this embodiment, the opening 151 is axially provided on the lower cover 150. The opening 151 includes a first hole section 152 and a second hole section 153. The first conductor 220 sequentially passes through the first hole section 152 and the second hole section 153 and then extends out of the lower cover 150. The aperture of the second hole section 153 is larger than that of the first hole section 152. Glue is filled in the second hole section 153 to fix the first conductor 220. A plurality of second conductors 230 extend out of the housing 100 from the air inlet 154. Since the first conductor 220 is fixedly connected to the lower cover 150, when the lower cover 150 is pulled outwards, the heating component 200 will be taken out, which is convenient for replacing the heating component 200.
[0051] In this embodiment, the heating component 200 further includes a second liquid guiding body 240. The second liquid guiding body 240 is a hollow cylinder. A plurality of heating elements 210 are attached to the inner wall of the second liquid guiding body 240. The outer wall of the second liquid guiding body 240 is attached to the inner wall of the first liquid guiding body 160 for transmitting the oil liquid of the first liquid guiding body 160 to the heating elements 210. Specifically, the second liquid guiding body 240 is made of cotton material like the first liquid guiding body 160 and has the effect of absorbing liquid and flowing in the second liquid guiding body 240. Specifically, the second liquid guiding body 240 is cotton for guiding oil. Specifically, the axial length of the second liquid guiding body 240 is slightly longer than the axial length of the heating element 210, so that the heat of the heating element 210 can be conducted to the second liquid guiding body 240 with the highest efficiency.
[0052] In this embodiment, the heating component 200 further includes a heat insulation housing 250. The heat insulation housing 250 is a sleeve. The heat insulation housing 250 is arranged between the second liquid guiding body 240 and the first liquid guiding body 160. An opening is provided on the heat insulation housing 250 for the second liquid guiding body 240 to contact the first liquid guiding body 160. Specifically, as Figure 6 and Figure 9As shown, the opening is provided in the lower part and the side part of the heat-insulating housing 250. The second liquid guide body 240 extends out of the opening in the lower part and is squeezed with the first liquid guide body 160 to increase the flow rate of the liquid between the two. The axial length of the heat-insulating housing 250 is greater than the axial length of the second liquid guide body 240, but less than the axial length of the first liquid guide body 160. A protrusion is provided on the inner side wall of the lower cover 150, and the bottom of the heat-insulating housing 250 abuts against this protrusion for convenient positioning. During installation, first install the heating component 200 on the lower cover 150. The first conductor 220 passes through the opening 151, and multiple second conductors 230 pass through the air inlet 154. The bottom of the heat-insulating housing 250 abuts against the protrusion on the inner side wall of the lower cover 150. Then push the lower cover 150 to insert the heating component 200 into the first liquid guide body 160 until the lower cover 150 abuts against the outer housing 140. Then drop glue into the second hole section 153 of the opening 151 to complete the installation.
[0053] Specifically, by arranging the heat-insulating housing 250 between the second liquid guide body 240 and the first liquid guide body 160, when the heating part heats the second liquid guide body 240, heat transfer to the first liquid guide body 160 can be blocked, thereby preventing heat from being transferred to the liquid storage device of the electronic cigarette, further reducing the probability of carbon deposition problems, and also avoiding the problem that the liquid storage device of the traditional electronic cigarette is prone to failure when heated during use.
[0054] As Figure 3 shown, in this embodiment, a bent groove 251 is provided on the heat-insulating housing 250. One end of the first conductor 220 is fixedly arranged on the inner wall of the second liquid guide body 240. The other end of the first conductor 220 is bent along the end of the second liquid guide body, the bent groove 251, and the outer wall of the heat-insulating housing 250 in sequence and then passes through the opening 151 and extends out. Optionally, a groove for avoiding the first conductor 220 is provided on the inner side wall of the first liquid guide body 160.
[0055] As Figure 6 and Figure 9 shown, in this embodiment, the atomization core assembly further includes a first support member 300 and a second support member 400. The first support member 300 is a cylindrical long rod, which is used to be inserted into the center of the heating component 200 to support the heating component 200 and prevent the heating component 200 from being squeezed and deformed during the transportation of the atomization core assembly. Optionally, a plurality of axial grooves can be provided on the first support member 300 for avoiding the first conductor 220. The second support member 400 has a structure similar to a gear and is arranged in the heat-insulating housing 250. The center is empty for air flow to pass through and is also used for the first support member 300 to pass through. The gear protrusions are used to clamp the first conductor 220 and the second conductor 230 to prevent their displacement or deformation. The first support member 300 needs to be pulled out before use to avoid affecting the fog flow.
[0056] Another embodiment of the present utility model further provides an electronic cigarette, which includes a mouthpiece, a liquid storage device, and the atomization core assembly as described above. The mouthpiece is fixedly connected to one end of the air outlet 131 of the air flow channel 110. The liquid storage device includes a liquid storage cavity communicated with the liquid guiding hole 120. The atomization core assembly is used to atomize the liquid in the liquid storage cavity and flow out from the mouthpiece.
[0057] In summary, the embodiments of the present utility model can control the independent working conditions of multiple heating parts through multiple second conductors 230, thereby adjusting the atomization amount; the alternating operation of the heating parts can also increase the service life and reduce the problem of carbon deposition; moreover, the layout structure of the multiple conductors is reasonably designed, having the advantages of compact structure and small occupied space.
[0058] Moreover, the first conductor 220 is electrically connected to multiple heating parts to form a common power supply end for the multiple heating parts. Multiple second conductors 230 are respectively electrically connected to another electrode to form a circuit, and the energization conditions of different second conductors 230 are controlled to drive the corresponding heating parts to work. This control circuit has a simple structure and small occupied volume, is suitable for the narrow space of the electronic cigarette, and can significantly reduce the occupied volume of the atomization core assembly with multiple heating parts.
[0059] Moreover, a heat insulation housing 250 is provided between the second liquid guide 240 and the first liquid guide 160, which can prevent heat from being transferred to the first liquid guide 160 when the heating part heats the second liquid guide 240, and further prevent heat from being transferred to the liquid storage device of the electronic cigarette, further reducing the probability of the occurrence of the carbon deposition problem, and also avoiding the problem that the liquid storage device of the traditional electronic cigarette is prone to failure when heated during use.
[0060] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
