The atomization component of the electronic atomization device known by the applicant usually includes a liquid absorption element and a heating element. Generally, the liquid absorption element is generally a glass fiber rope, and the heating element is generally a spiral heating wire.

The liquid absorbing element of the above atomization component adopts porous ceramic material, which has the advantages of high temperature resistance, not easy to be ablated at high temperature, and will not be burnt to produce a burnt smell. However, its disadvantage is that the liquid absorbing surface of the liquid absorbing element is large and is The liquid surface of the liquid reservoir is in direct contact, resulting in a large amount of liquid that is too saturated and easy to cause liquid leakage. Therefore, it is necessary to use a liquid storage medium in the liquid reservoir to slow down the transmission speed of the smoke liquid and reduce the occurrence of liquid leakage.

The present invention will be described in further detail below in conjunction with the accompanying drawings:

Example

As shown in Figures 1 and 2, the atomization component of the smoking device of the present invention includes: a casing 1 made of ceramics, an inner absorption layer 2 made of microporous ceramics, and an inner absorption layer 2 embedded in the inner absorption layer 2 The resistance heating element 3, the lead 4 of the resistance heating element 3, the atomization cavity 5 of the inner absorption layer 2 and the air inlet channel 6 communicating with the atomization cavity 5.

The housing 1 is made of a single solid ceramic, the central body 7 is configured in a truncated cone shape, the axial section of which is V-shaped, the side of the central body 7 is provided with a side through hole 8, and the lower and upper parts of the housing 1 are respectively provided There are intake branch pipes 9 and exhaust branch pipes 10. The casing 1 is used to block the inner absorption layer 2 and the smoke liquid storage cavity 25, supports and installs the inner absorption layer 2, and is used to connect the spray tube 22 and the base 14. The material of the shell 1 is made of solid ceramics, which is helpful for heat insulation, high temperature resistance, and prevention of deformation at high temperatures.

The inner absorption layer 2 is made of porous microporous ceramics, is in the shape of a truncated cone and fits inside the casing 1, wherein the axial section is V-shaped, and the side surface has side protrusions 11, and the side protrusions 11 are inserted into the casing 1 correspondingly In the through hole 8 of the central body 7.

The porous microporous ceramic of the inner absorption layer 2 must be non-conductive, non-toxic and thermally stable.

When the inner absorption layer 2 is made, other embodiments can also use any other non-conductive, non-toxic and thermally stable microporous material instead of the microporous ceramic.

The casing 1 is used to install and support the inner absorption layer 2 and connect the spray tube 22 and the base 14. The casing 1 does not conduct the liquid to be atomized, and the liquid substance to be atomized in the liquid storage cavity 25 passes through the side of the casing 1. The through hole 8 is absorbed by the side protrusions 11 of the inner absorption layer 2 and enters the inner absorption layer 2. The resistance heating element 3 inside the inner absorption layer 2 can heat the surrounding liquid material, and the heated liquid material becomes steam It evaporates from the inner wall of the inner absorption layer 2 and collects in the atomization cavity 5. The central body 7 of the housing 1 is designed to have a V-shaped frustum shape in order to facilitate the installation of the V-shaped frustum-shaped inner absorption layer 2. The inner absorption layer 2 is designed to be a V-shaped frustum shape, and its internal atomization cavity 5 also becomes a V-shaped truncated cone shape, which can increase the area of the inner surface of the atomization cavity 5, and the larger inner surface area of the atomization cavity 5 can increase the amount of liquid evaporation and improve the atomization efficiency, and the cross-section is V-shaped It has the same shape as the horn, which can accelerate the outward flowing fluid (aerosol), diverge outward, and discharge the vapor (aerosol) formed by the evaporation and atomization of the liquid in time, which can improve the working efficiency of the atomization core. The inner absorption layer 2 extends from the side through hole 8 to the liquid storage cavity 25 through the side protrusions 11, instead of the entire area contacting the absorption liquid storage cavity 25, which has the function of restricting or throttling and preventing the inner absorption layer 2 from being excessive. The liquid material in the liquid storage chamber 25 is absorbed and the liquid leakage occurs when the liquid exceeds the saturation state.

The air intake passage 6 is connected to the atomization cavity 5 through a peripheral air supply hole 12, and the peripheral air supply hole 12 is opened on a baffle 13 located in the intake branch pipe 9 of the housing 1. The main function of the design of the baffle 13 is to block the condensate dripping from the atomization chamber 5 or the droplets that are not atomized. The peripheral air supply hole 12 is relatively small and does not affect the air intake, but the condensate or the droplets that are not atomized. It is not easy to leak downward to the base 14 through the outer peripheral air supply hole 12 to avoid long-term liquid leakage and corrosion of the base 14.

As shown in Figs. 3 and 4, in this embodiment, the resistance heating element 3 is designed in a truncated cone shape, and the resistance heating element 3 can be made of sheet metal and configured in a zigzag bar shape. Compared with the spiral heating wire, the resistance heating element 3 of this shape has a larger area to contact the liquid substance to be atomized, and can heat the liquid substance more and faster when it generates heat, thereby improving the heating efficiency.

As shown in Figs. 5 and 6, in another embodiment, the resistance heating element 3 may be made of metal wires and configured in a mesh shape. The resistance heating element 3 of this shape also has a larger area to contact the liquid substance to be atomized, which improves the heating efficiency.

As shown in Figs. 1, 2, and 7, the outer diameter of the intake branch pipe 9 is smaller than the outer diameter of the middle main body 7 where it is connected, and a step is formed between the two. The intake branch pipe 9 is inserted into the base 14 and connected to the base 14, and the above-mentioned step is used to limit and fix the housing 1.

As shown in FIGS. 1, 2 and 7, the outer diameter of the exhaust branch pipe 10 is smaller than the outer diameter of the middle body 7 where it is connected, and a step is formed between the two. The exhaust branch pipe 10 is inserted into the spray pipe 22 and connected to the spray pipe 22. The above-mentioned step is used to limit and fix the housing 1 and the spray pipe 22.

The main function of the atomization component is to provide a thermal process to convert the smoke liquid of the electronic atomization device into aerosol (vapor).

The e-liquid of the electronic atomization device is made on the basis of a mixture of glycerin, propylene glycol and flavoring agents. The mixture may contain nicotine or nicotine salts or oily vegetable liquids.

In order for the atomization component to work normally as a part of the electronic atomization device, electronic cigarette or smoking device, the following conditions should be provided:

Fully supply the liquid stored in the reservoir to the absorbing element (wick) and electric heating element;

Supply fresh air to the atomization cavity;

Discharge aerosol from the atomization chamber;

Power is supplied to the electric heating element when inhaling.

As a component of the electronic atomization device, the atomization assembly should be operated according to the method shown in FIG. 7. The atomization assembly disclosed in the invention is used in the electronic atomization device, and the electronic atomization device is as follows.

As shown in Fig. 7, an atomizer in which the atomization assembly (1-13) of the present invention is installed. The atomizer may be made of a transparent material, so that it is convenient to observe the amount of smoke liquid. The atomizer is composed of the following components: a base 14, a sealing ring 15, and an air inlet 16, an air passage 17, an air inlet pipe 18 connected with the air inlet channel 6 of the atomization assembly, a central contact element 19 and an external threaded contact element 20. Insulation seat 21, spray tube 22, housing 24 with liquid storage cavity 25 and suction nozzle 26. Wherein, the intake branch pipe 9 of the atomization assembly housing 1 is installed on the base 14 through a sealing ring 15, and the sealing ring 15 may be made of silicone sealant. The central contact element 19 and the external threaded contact element 20 are respectively connected to the two leads 4 of the atomization assembly, and are separated from each other by an insulating seat 21, which can be made of silicone material. The exhaust branch pipe 10 of the atomization component housing 1 is embedded in the spray pipe 22 through a sealing ring 23 (which may be made of silicone sealant).

Before use, inject e-liquid into the liquid storage chamber 25 of the atomizer, and connect its central contact element 19 and external threaded contact element 20 to the appropriate contacts of the power source, so that the resistance heating element 3 of the atomizer assembly can pass through Its lead 4 is connected to the power source.

The resistance heating element 3 in the inner absorption layer 2 is used for heating, and heats and atomizes the smoke liquid in the inner absorption layer 2 into aerosol (vapor).

Since the outer surface area of the side protrusions 11 is much smaller than the surface area of the inner absorption layer 2 in the atomization cavity 5 of the atomization assembly, the amount of liquid inflow is limited, and the smoke liquid entering from the side protrusions 11 will be diffused and distributed. In the inner absorption layer 2, the smoke liquid in the inner absorption layer 2 will not excessively gather on the surface of the inner absorption layer 2 located in the atomization cavity 5 of the atomization assembly to overflow, and the inner absorption layer 2 is contained in the microceramic pores of the atomization assembly. The liquid-containing liquid has surface tension. Therefore, when the atomization assembly is not working, the smoke liquid will reach a balance in the inner absorption layer 2, and the liquid will not flow from the inner absorption layer 2 to the micropores on the surface of the atomization cavity 5 of the atomization assembly. In this way, liquid leakage can be prevented.

Air enters the atomization cavity 5 through the outer peripheral air supply hole 12, and the outer peripheral air supply hole 12 is opened on the baffle 13 which is located in the intake branch 9 of the atomization assembly housing 1.

During the smoking process, when the user inhales, the air enters the atomization assembly from the atmosphere through the air-supply atomizer system. To be precise, it passes through the air inlet 16, the air duct 17, and the air inlet pipe 18, and then passes through the air inlet. The air passage 6 and the peripheral air supply hole 12 on the baffle 13 enter the atomization cavity 5 of the atomizer.

When the user inhales, the power supply voltage is supplied to the lead 4, and the lead 4 is energized to the resistance heating element 3 through the connection of the central contact element 19 and the external thread contact element 20, and the resistance heating element 3 starts to heat up quickly (the maximum allowable temperature can reach + 290-300ºC).

The liquid located in the area of the resistance heating element 3 starts to be actively atomized into the atomization chamber 5 in the form of aerosol, and it is mixed with the air entering through the outer peripheral air supply hole 12 opened on the baffle 13, which is located in the atomization assembly In the intake branch pipe 9 of the housing 1.

Then, the air mixture flows through the spray tube 22, through the suction nozzle 26, and reaches the user's mouth.

In this way, the design of the atomization component of the electronic atomization device disclosed in the present invention can increase the intensity of liquid atomization and aerosol generation, which can improve the smoke heating effect, thereby improving the resistance heating element and air in the atomization cavity. The heat exchange conditions between and aerosols.
