Description

[Technical field]

[0001] The present invention relates to the technical field of atomization, and in particular to an atomization device. [Background technology]

[0002] Usually, an atomizing device includes an atomizing core as a core component and other components. The atomizing core usually includes a liquid guiding element and a heating element. The main role of the liquid guiding element 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 the tobacco liquid to evaporate it.

[0003] In the conventional atomizing device, the atomizing chamber and the supply and exhaust holes of the atomizing chamber are determined by combining the liquid-guiding core and other components, and the aerosol generated by the heating element is transported by the airflow passing through the atomizing chamber. The size of the atomizing chamber and its supply and exhaust holes are determined by both the liquid-guiding core and other components. Furthermore, during the atomization process, the airflow entering the atomizing area affects the atomization effect, and the amount of airflow and the speed of flow also indirectly affect the atomization effect and stability. Therefore, the assembly of the atomizing core and the structure of other components all affect the size, speed and path of the airflow, which in turn affects the atomization effect, making it difficult to ensure the atomization effect of the atomizing device.

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.

The porous material is, for example, a porous ceramic material. The liquid guiding element 1 includes an air guiding portion 12 and a base portion 11 that is connected to the air guiding portion 12 and surrounds the outer periphery of the air guiding portion 12.

The porous material may be a porous ceramic material.

Liquid supply part 14 When the liquid comes into contact with the liquid, the liquid guiding member 1 transfers the liquid to the heat generating portion 21 of the heat generating element 2, where the liquid is atomized by heating to form an aerosol. The airflow passes through the atomization 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 carries away the atomized aerosol.

[0034] The atomization device of the present invention has the following beneficial technical effects.

[0035] 1. The airflow chamber 17 of the atomizing core 0 in the atomizing device is made of a porous material Consists of The heating element 21 of the heating element 2 is disposed inside the airflow chamber 17. Therefore, the size, flow rate and path of the airflow are mainly determined by the structure of the liquid-guide 1 and are not affected by other parts of the nebulizer or the assembly relationship, which is advantageous to ensure good and consistent nebulization effect of the nebulizer.

[0036] 2. The liquid guiding core 1 of the atomizing device is made of a porous material. Consists of For airflow chamber 17 Around The entire material is made of a porous material, and condensation occurring within the air flow chamber 17 is absorbed by the liquid-guiding 1. Therefore, the generation of condensation can be effectively reduced.

[0037] 3. In the nebulizer, 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 parts of the nebulizer, so that the number of components in the structure of the nebulizer can be reduced, and the assembly can be made easy, fast, stable and reliable.

[0038] The atomizing device of the present invention can be applied to an electronic cigarette to atomize tobacco liquid by heating. The specific operation process is as follows: Liquid supply part 14 The liquid guide 1 contacts the tobacco liquid in the atomization device. The liquid guide 1 conveys the tobacco liquid to the heating portion 21 of the heating element 2, where it is heated and atomized into a vapor. The airflow then passes through the air intake path 34, the air intake port 15, the airflow chamber 17, the exhaust port 16, and the exhaust path 33 in that order, carrying the vapor out of the atomization device and allowing the smoker to inhale it.

[0039] Preferably, the liquid conductor 1 is integrally moulded.

Alternatively, the airflow chamber 17 may be a circular or polygonal space with corners. For example, when the airflow chamber 17 is a square (see Fig. 14), 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 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.

[0046] 2 to 5, an electrode connection hole 42 is preferably provided on the side of the sealing member 4 facing the base 32. The electrical connection portion 22 of the heating element 2 is bent and inserted into the electrode connection hole 42. One end of the electrode 5 passes through the base 32 and is inserted into the electrode connection hole 42, and comes into contact with the electrical connection portion 22 to be electrically connected. The other end of the electrode 5 is provided on the base 32 and is used for connection to an external circuit.

First portion 111 and second portion 112 surround opposite sides of air guiding portion 12, respectively. One end of first portion 111 and one end of second portion 112 are connected to each other and to air guiding portion 12.

[0048] 6 to 9, 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.

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.

[0050] In the above embodiment, preferably, the air inlet 15 is provided at the connection point between the base part 11 and the air guide part 12. In addition, the other end of the first part 111 and the other end of the second part 112 are spaced apart from each other and suspended in air, and define the air outlet 16.

[0051] 2 to 9, the casing 3 preferably includes a casing body 31 and a base 32. The casing 3 includes a casing body 31 and a base 32. The casing body 31 and the base 32 are made of a plastic. Liquid storage space 35 The exhaust path 33 is provided in the casing body 31, and the air supply path 34 is provided in the base 32. One end of the casing body 31 is open, and the atomization core 0 is provided inside the casing body 31. In addition, the base 32 is attached to the open end of the casing body 31.

[0053] The support section 13 maintains a gap between the air inlet 15 and the base 32 by abutting against the base 32 downward. The first role of this is to support the atomizing core 0, and the second role is to support the atomizing core 0 at a high position to expose the air inlet 15. The air guide section 12 allows the air current that enters by rising straight up from the air inlet 15 to move to the atomizing surfaces on both sides. In addition, Air conduction section 12 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 guiding member 1.

[0055] 1. The airflow chamber 17 of the atomizing device is determined not by both the liquid guide 1 and other parts, but by the structure of the liquid guide 1, so that the number of structural parts of the atomizing device is reduced, and assembly is simple and reliable. When assembling, the atomizing core 0 is first placed in the sealing member 4, and then attached to the base 32. Next, the liquid to be atomized is poured into the sealing member 4. Liquid storage space 35 After the inside is filled with the liquid, a part of the assembled base 32 is inserted into the casing body 31, and then the electrode 5 is attached.
