Description

[Technical field]

[0001] The present invention relates to the technical field of atomization, and in particular to an atomizing core having an airflow chamber. [Background technology]

[0002] As the core component of an atomizer, the atomizing core generally includes a liquid conductor and a heating element. The main role of the liquid conductor is to transfer the liquid to the heating element and to heat and atomize it. Meanwhile, the main role of the atomizing core of an atomizer used in an electronic cigarette is to transfer the tobacco liquid and heat and evaporate the tobacco liquid.

[0003] Conventionally, the atomizing core is assembled with other components to form an atomizer, and then the atomizing chamber and the supply and exhaust holes of the atomizing chamber are defined by the atomizing core and other components. In addition, the heating part of the heating element heats the liquid to generate aerosol, and the airflow transports the aerosol. However, when the atomizing chamber and the supply and exhaust holes of the atomizing chamber are defined by the atomizing core and other components in this way, the airflow entering the atomizing chamber and the supply and exhaust holes affects the atomization effect, and the amount of airflow and the speed of the flow also indirectly affect the atomization effect and stability. Therefore, if the assembly of the atomizing core and other components is not precise enough or is poorly uniform, the atomization effect of the atomizing core will be affected. Summary of the Invention [Problem to be solved by the invention]

Thus, when a feature such as "first", "second", "third", etc. is limited, it may include one or more of the feature explicitly or implicitly. Those skilled in the art can interpret the specific meaning of the above terms in the present invention according to the specific situation.

[0021] In the following description, for purposes of explanation and not limitation, specific details are presented, such as particular system structures and techniques, to provide a thorough understanding of embodiments of the present invention. However, it will be apparent to one skilled in the art that the present invention can be practiced in other embodiments that do not include these specific details. In other circumstances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary details.

[0022] 1 to 4, the atomizing core in one embodiment of the present invention includes a heating element 2 and a liquid guide 1, which is a porous material for absorbing and transmitting liquid. A large number of micropores are distributed in the so-called porous material (which may also be called a microporous material), and this material realizes the absorption and transmission of liquid. The porous material is, for example, a porous ceramic material. The liquid guide 1 includes an air guide section 12 and a base section 11 that is connected to the air guide section 12 and surrounds the outer periphery of the air guide section 12. An air flow chamber 17 is formed in the gap between the air guide section 12 and the base section 11. The liquid guide 1 is also provided with an air inlet 15 communicating with the air flow chamber 17, an exhaust port 16 communicating with the air flow chamber 17, and a liquid supply portion 14 for contacting the liquid. The heating element 2 includes a heating section 21 that generates heat when energized, and an electrical connection section 22 that is connected to the heating section 21 and transmits an electric current to the heating section 21. The heating section 21 is provided on the inner wall of the air flow chamber 17 so as to be in contact with the liquid guide 1. Furthermore, the electrical connection portion 22 extends outside the airflow chamber 17. Thus, when the liquid supply portion 14 of the liquid guide 1 comes into contact with the liquid, the liquid guide 1 transfers the liquid to the heat generating portion 21, which heats the liquid and generates an aerosol. Furthermore, an external airflow enters the airflow chamber 17 from the air supply port 15 and carries the aerosol out through the air exhaust port 16. The porous material may be a porous ceramic material.

[0023] In the atomizing core of the present invention, when the liquid supply portion 14 of the liquid guide 1 comes into contact with the liquid, the liquid guide 1 transfers the liquid to the heat generating portion 21 of the heat generating element 2, where the liquid is atomized by heating to produce an aerosol. In addition, the airflow passes through the atomizing surface (the portion in the heat generating portion 21 of the heat generating element 2 where the liquid is heated to generate an aerosol), and the atomized aerosol is carried out.

[0024] The atomizing core of the present invention has the following beneficial technical effects:

[0025] 1. The airflow chamber 17 is provided inside the liquid-guide 1, which is a porous material, and the heating part 21 of the heating element 2 is provided inside the airflow chamber 17. Therefore, the size, flow rate and path of the airflow are determined mainly by the structure of the liquid-guide 1 and are not affected by other parts or assembly relationships, which is advantageous in ensuring the consistency of the atomization effect.

[0026] 2. Since the liquid guiding 1 is a porous material, the entire inside of the air flow chamber 17 becomes a porous material, and the condensate generated in the air flow chamber 17 is absorbed by the liquid guiding 1. Therefore, the generation of condensate can be effectively reduced.

[0027] 3. When the atomizing core of the present invention is applied to an atomizing device, the airflow chamber 17 is mainly determined by the structure of the liquid guide 1, and the liquid guide 1 does not need to define the airflow chamber 17 together with other components, so that the number of components in the structure of the atomizing device can be reduced, and the assembly can be made easy, fast, stable and reliable.

[0028] The atomizing core of the present invention can be applied to the atomizing device of an electronic cigarette, and is used for heating and atomizing tobacco liquid. The specific operation process is as follows: the liquid supply portion 14 of the liquid guide 1 of the atomizing core contacts the tobacco liquid of the atomizing device. The liquid guide 1 transfers the tobacco liquid to the heating portion 21 of the heating element 2, and is heated to atomize the liquid into vapor. Then, the external airflow enters through the air inlet, and carries the vapor out through the exhaust port for the smoker to inhale.

[0029] Preferably, the liquid conductor 1 is integrally moulded.

[0030] The structure of the airflow chamber 17 of the atomizing core can be any pattern, but in order to make it easier to mold the heating element 2, the airflow chamber 17 may be a circular space (see Figs. 1 to 4) or a circular space with corners (see Fig. 5). For example, when it is a polygonal ring shape, the heating part 21 of the heating element 2 includes multiple flat atomizing surfaces. In this case, it is easier to control the uniformity of the molding of the heating element 2, and the stability of fitting with the porous material is improved. No further examples of the atomizing surface and the airflow chamber 17 of various other shapes will be given. The heating part 21 of the heating element 2 includes at least one heating circuit, and the heating circuit is bent into a ring shape.

[0031] 1 to 4, in some embodiments, in air flow chamber 17, heat generating section 21, a side wall of air conducting section 12 and a side wall of base section 11 have corresponding shapes and are all annular. Heat generating section 21 of heat generating element 2 is provided on the side wall of base section 11, and liquid supply section 14 is provided on the outside of base section 11. Liquid supply section 14 may be a liquid supply recess provided on the outside of base section 11.

[0032] 6 to 9, in some other embodiments, in the air flow chamber 17, the heat generating portion 21, the side wall of the air guide portion 12, and the side wall of the base portion 11 have corresponding shapes and are all annular. The heat generating portion 21 of the heat generating element 2 is provided on the side wall of the air guide portion 12. As can be understood, in the air flow chamber 17, the heat generating portion 21 may be provided on both the air guide portion 12 and the side portion of the base portion 11. The liquid supply portion 14 is a liquid supply recess provided on the outside of the air guide portion 12.

[0033] Preferably, the base portion 11 includes a first portion 111 and a second portion 112. The first portion 111 and the second portion 112 respectively surround opposite sides of the air guiding portion 12. One end of the first portion 111 and one end of the second portion 112 are connected to each other and to the air guiding portion 12.

[0034] Preferably, the air inlet 15 is provided at a connection point between the base portion 11 and the air guide portion 12 .

[0035] Preferably, the other end of the first portion 111 and the other end of the second portion 112 are spaced apart and suspended in air, and define an exhaust port 16 .

[0036] Preferably, the air inlet 15 is provided below the liquid guide 1. The liquid guide 1 includes a support 13 connected to the base 11 and / or the air guide 12, protruding downward, and for lifting the air inlet 15. The first role of the support 13 is to support the atomizing core, and the second role is to support the atomizing core at a high position to expose the air inlet 15. The air guide 12 allows the airflow that has entered by rising straight up from the air inlet 15 to move to the atomizing surfaces on both sides. The air guide 12 is also made of a porous material. The atomized aerosol in the air flow chamber 17 is unlikely to condense, but even if it does condense, the condensed liquid can be absorbed by the liquid guide 1.

[0037] From the above, the atomizing core of the present invention has the following beneficial technical effects.

[0038] 1. The airflow chamber 17 is provided inside the liquid-guide 1, which is a porous material, and the heating part 21 of the heating element 2 is provided inside the airflow chamber 17. Therefore, the size, flow rate and path of the airflow are determined mainly by the structure of the liquid-guide 1 and are not affected by other parts or assembly relationships, which is advantageous in ensuring the consistency of the atomization effect.

[0039] 2. Since the liquid guiding 1 is a porous material, the entire inside of the air flow chamber 17 becomes a porous material, and the condensate generated in the air flow chamber 17 is absorbed by the liquid guiding 1. Therefore, the generation of condensate can be effectively reduced.

[0040] 3. When the atomizing core of the present invention is applied to an atomizing device, the airflow chamber 17 is mainly determined by the structure of the liquid guide 1, and the liquid guide 1 does not need to define the airflow chamber 17 together with other components, so that the number of components in the structure of the atomizing device can be reduced, and the assembly can be made easy, fast, stable and reliable.

[0041] The above description is merely a preferred embodiment of the present invention, and does not limit the present invention. For those skilled in the art, there may be various modifications, combinations and variations in the present invention. Any modifications, equivalent replacements, improvements, etc., made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
