Description

The present invention relates to the technical field of atomization, and in particular to an atomization core having an airflow chamber.

As the core component of an atomizer, the atomizing core usually contains a liquid conductor and a heating element. The main role of the liquid conductor is to transfer the liquid to the heating element and atomize it by heating. The main role of the atomizing core of an atomizer used in an electronic cigarette is to transfer the tobacco liquid and heat it to evaporate it.

Conventionally, the atomizing core is assembled with other parts to form an atomizer, and then the atomizing core and other parts define the atomizing chamber and the supply and exhaust holes of the atomizing chamber. The heating part of the heating element heats the liquid to generate an 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 parts 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 with the other parts is not precise enough or if they are not uniform enough, the atomization effect of the atomizing core is affected.

The technical problem that the present invention aims to solve is to provide an atomizing core having an improved airflow chamber, which addresses the above-mentioned shortcomings in the related art.

The technical solutions adopted by the present invention to solve the technical problems are as follows:

The present invention provides an atomizing core including a heating element and a liquid guiding member that is a porous material for absorbing and transmitting liquid. The liquid guiding member includes an air guiding portion and a base portion that is connected to the outer periphery of the air guiding portion and surrounds it. An airflow chamber is formed in the gap between the air guiding portion and the base portion. The liquid guiding member is provided with an air inlet port that communicates with the airflow chamber, an exhaust port that communicates with the airflow chamber, and a liquid supply portion for contacting the liquid. The heating element includes a heating portion that generates heat when energized, and an electrical connection portion that is connected to the heating portion and transmits current to the heating portion. The heating portion is provided on the inner wall of the airflow chamber so as to come into contact with the liquid. As a result, when the liquid supply portion of the liquid guiding member comes into contact with the liquid, the liquid guiding member transmits the liquid to the heating portion, heats it, and generates an aerosol. Furthermore, an external airflow enters the airflow chamber from the air inlet port and carries the aerosol out of the exhaust port.

Preferably, the airflow chamber is a circular or angular annular space.

Preferably, the base portion includes a first portion and a second portion. The first portion and the second portion surround both sides of the air guide portion, respectively. One end of the first portion and one end of the second portion are connected to each other and to the air guide portion.

Preferably, in the airflow chamber, the heat generating portion is provided in the base portion, and the liquid supply portion is provided outside the base portion.

Preferably, the liquid supply portion is a liquid supply recess provided on the outside of the base portion.

Preferably, in the airflow chamber, the heat generating section is provided in the air guide section.

Preferably, the liquid supply portion is a liquid supply recess provided on the outside of the air guide portion.

Preferably, the air inlet is provided at the connection between the base and the air guide.

Preferably, the other end of the first portion and the other end of the second portion define the exhaust port.

Preferably, the air inlet is provided below the liquid guide. The liquid guide includes a support portion connected to the base portion and/or the air guide portion, protruding downward, and for lifting the air inlet.

Implementing the technical solution of the present invention has at least the following beneficial effects:

The atomizing core has an airflow chamber disposed inside a liquid-guiding material made of a porous material, and the heating element's heat generating portion is disposed inside the airflow chamber. Therefore, the size, flow rate and path of the airflow are determined primarily by the structure of the liquid-guiding material, and are not affected by other parts or assembly relationships, which is advantageous in ensuring uniformity of the atomization effect.

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 absorbs and transmits 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 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 contact the liquid guide 1. In addition, the electrical connection portion 22 extends outside the airflow chamber 17. As a result, 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 it and generates an aerosol. In addition, an external airflow enters the airflow chamber 17 from the air supply port 15 and carries the aerosol out through the exhaust port 16. The porous material may be a porous ceramic material.

In the atomizing core of the present invention, when the liquid supply portion 14 of the liquid guiding element 1 comes into contact with the liquid, the liquid guiding element 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 that heats the liquid in the heat generating portion 21 of the heat generating element 2 to generate an aerosol), and the atomized aerosol is discharged.

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

1. The airflow chamber 17 is provided inside the liquid-guiding member 1, which is a porous material, and the heat generating portion 21 of the heat generating element 2 is provided inside the airflow chamber 17. Therefore, the size, flow rate, and path of the airflow are determined primarily by the structure of the liquid-guiding member 1 and are not affected by other parts or assembly relationships, which is advantageous in ensuring the consistency of the atomization effect.

2. Because the liquid-guiding member 1 is a porous material, the entire airflow chamber 17 is made of porous material, and the condensate generated in the airflow chamber 17 is absorbed by the liquid-guiding member 1. This effectively reduces the generation of condensate.

3. When the atomizing core of the present invention is applied to an atomizing device, the airflow chamber 17 is determined mainly by the structure of the liquid guide 1, and there is no need for the liquid guide 1 to define the airflow chamber 17 together with other parts. Therefore, the number of components in the structure of the atomizing device can be reduced, and assembly is easy, speedy, stable and reliable.

The atomizing core of the present invention can be applied to an atomizing device for electronic cigarettes, and is used to heat and atomize tobacco liquid. The specific operating process is as follows: The liquid supply portion 14 of the liquid guide 1 of the atomizing core comes into contact with 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, where it is heated and atomized into vapor. Then, external airflow enters through the air intake port, carries the vapor out through the exhaust port, and is inhaled by the smoker.

Preferably, the liquid guide 1 is integrally molded.

The structure of the airflow chamber 17 of the atomizing core can be any pattern, but to make it easier to mold the heating element 2, the airflow chamber 17 may be a circular space (see Figures 1 to 4) or a circular space with corners (see Figure 5). For example, if 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 the fit with the porous material is improved. No further examples of atomizing surfaces and airflow chambers 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.

Referring to Figures 1 to 4, in some embodiments, in the airflow chamber 17, the shapes of the heat generating section 21, the side wall of the air conducting section 12, and the side wall of the base section 11 correspond to each other and are all annular. The heat generating section 21 of the heat generating element 2 is provided on the side wall of the base section 11, and the liquid supply area 14 is provided on the outside of the base section 11. The liquid supply area 14 may be a liquid supply recess provided on the outside of the base section 11.

Referring to Figures 6 to 9, in some other embodiments, in the airflow chamber 17, the heat generating section 21, the sidewall of the air guide section 12, and the sidewall of the base section 11 have corresponding shapes, and are all annular. The heat generating section 21 of the heating element 2 is provided on the sidewall of the air guide section 12. As can be seen, in the airflow chamber 17, the heat generating section 21 may be provided on both the air guide section 12 and the side of the base section 11. The liquid supply area 14 is a liquid supply recess provided on the outside of the air guide section 12.

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

Preferably, the air intake 15 is provided at the connection point between the base portion 11 and the air guide portion 12.

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 the exhaust port 16.

The air inlet 15 is preferably provided below the liquid guide 1. The liquid guide 1 includes a support 13 that is connected to the base 11 and/or the air guide 12, protrudes downward, and lifts the air inlet 15. The first role of the support 13 is to support the atomization core, and the second role is to support the atomization core at a high position to expose the air inlet 15. The air guide 12 allows the airflow that has risen straight up from the air inlet 15 to move to the atomization 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.

As a result of the above, the atomizing core of the present invention has the following beneficial technical effects:

1. The airflow chamber 17 is provided inside the liquid-guiding member 1, which is a porous material, and the heat generating portion 21 of the heat generating element 2 is provided inside the airflow chamber 17. Therefore, the size, flow rate, and path of the airflow are determined primarily by the structure of the liquid-guiding member 1 and are not affected by other parts or assembly relationships, which is advantageous in ensuring the consistency of the atomization effect.

2. Because the liquid-guiding member 1 is a porous material, the entire airflow chamber 17 is made of porous material, and the condensate generated in the airflow chamber 17 is absorbed by the liquid-guiding member 1. This effectively reduces the generation of condensate.

3. When the atomizing core of the present invention is applied to an atomizing device, the airflow chamber 17 is determined mainly by the structure of the liquid guide 1, and there is no need for the liquid guide 1 to define the airflow chamber 17 together with other parts. Therefore, the number of components in the structure of the atomizing device can be reduced, and assembly is easy, fast, stable and reliable.

The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art may have various modifications, combinations and variations of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are all intended to be included in the scope of the claims of the present invention.
