Description

Technical Field

[0001] The utility model relates to an atomization device, in particular to a heating module of an electronic atomization device. Background Art

[0002] Electronic cigarettes are an electronic product that imitates cigarettes. Since the harmful components in tobacco enter the human body through smoking and will cause adverse effects, electronic cigarettes have developed rapidly by controlling the harmful substances by controlling the components of the e-liquid without affecting the habits and physical sensations of smokers.

[0003] As the e-cigarette market continues to expand, consumers have higher and higher requirements for the atomization effect, taste restoration and stability of e-cigarettes. In order to improve the atomization effect of e-cigarettes, a heating module is usually used to heat the e-liquid to evaporate it into smoke. However, the existing heating modules have certain problems in controlling the heating temperature, heat loss and use efficiency, which restricts the further popularization and development of e-cigarettes.

[0004] Therefore, the utility model proposes a heating module for an electronic cigarette atomization device, aiming to improve the atomization effect, reduce heat loss, improve the use efficiency and prolong the service life. Utility Model Content

[0005] The utility model aims to provide a heating module for an electronic cigarette atomization device, which can improve the atomization effect, reduce heat loss, improve the use efficiency and prolong the service life.

[0006] Another object of the utility model is to provide an electronic atomization device with good atomization effect, low energy consumption and long service life.

[0007] In order to achieve the above-mentioned purpose, the heating module of the electronic atomization device provided by the utility model includes a glass substrate, a conductive heating layer and a pair of electrodes, the conductive heating layer is arranged on the surface of the glass substrate, and the two electrodes are respectively arranged at the opposite ends of the surface of the conductive heating layer; the glass substrate is provided with a plurality of first micropores passing through its surface and bottom surface, and the conductive heating layer is provided with a plurality of second micropores passing through its surface and bottom surface; the first micropores are connected to the second micropores one-to-one.

[0008] Compared with the prior art, the utility model uses glass material as a substrate, and then sets a conductive heating layer on the surface of the glass substrate, and sets conductive electrodes at both ends of the conductive heating layer. When the conductive heating layer is energized through the two electrodes, the conductive heating layer can quickly generate heat and transfer the heat to the glass substrate. Micropores are opened on the surfaces of the glass substrate and the conductive heating layer in a one-to-one correspondence. Therefore, after the smoke oil passes through the micropores, the glass substrate can heat and atomize the smoke oil in the micropores. Since the conductive heating layer and the glass substrate have good thermal conductivity, the heat can quickly reach the micropores to heat the smoke oil, reduce heat loss, and thus greatly improve the atomization effect, increase the battery life, and extend the service life. In addition, the combination of the glass substrate and the conductive heating layer has low material cost and easy processing, so the production cost of the electronic atomization device can be reduced.

[0009] Preferably, the conductive heating layer is a thin film resistor layer, which is disposed on the surface of the glass substrate by PVD sputtering, so that the conductive heating layer can be processed more easily and the production cost can be reduced.

[0010] Preferably, the conductive heating layer is a thick film resistor layer, which is arranged on the surface of the glass substrate by printing, so that the conductive heating layer can be processed more easily and the production cost can be reduced.

[0011] Preferably, the diameter of the first micropore and the second micropore is between 3 and 100 microns, and the distance between two adjacent micropores is between 2 and 100 microns. This arrangement can make heat transfer faster and more uniform on the one hand, and on the other hand, it can improve the atomization ability of each micropore to the e-liquid, thereby improving the atomization effect.

[0012] Preferably, the thickness of the conductive heating layer is between 0.1-500 microns.

[0013] Preferably, the resistance value of the conductive heating layer is between 0.1-100 ohms.

A smoke passage 14 is disposed in the housing 1 , and the smoke passage 14 penetrates the smoke oil chamber 12 and the upper cavity 2 a 1 , and is communicated with the suction nozzle 11 and the lower cavity 2 a 2 , respectively.

[0025] See also Figure 1 , Figure 2 and Figure 3 , the mounting seat 2 includes a pressure cover 21, a packaging seat 22 and a support seat 23, and the pressure cover 21 and the packaging seat 22 are detachably sealed and combined to enclose the accommodating cavity 2a. By providing the pressure cover 21 and the packaging seat 22, the mounting seat 2 can be made into a detachable structure, so as to facilitate the installation of the heating module 3 therein and improve the convenience of assembly. The support seat 23 is arranged in the accommodating cavity 2a, and a step surface 231 is provided on the support seat 23, and the heating module 3 is arranged on the step surface 231. The support seat 23 is provided to facilitate the positioning of the heating module 3 inside the mounting seat 2, and at the same time, the pressure cover 21 is used to press and hold the heating module 3 in position, so that the firmness and stability of the heating module 3 can be ensured.

[0026] Please see again Figure 2 and Figure 3, the mounting seat 2 also includes a first sealing ring 24 and a second sealing ring 25, the first sealing ring 24 is arranged between the surface of the heating module 3 and the inner bottom surface of the pressure cover 21, and the second sealing ring 25 is arranged between the bottom surface of the heating module 3 and the step surface 231. The first sealing ring 24 and the second sealing ring 25 are arranged to prevent the smoke oil and the atomized gas from leaking out from between the components, thereby ensuring the working stability of the atomization device 100. The bottom of the smoke oil chamber 12 and the mounting seat 2 are respectively provided with a smoke oil channel 2b connecting the smoke oil chamber 12 and the upper cavity 2a1. An oil seal gasket 26 is arranged between the surface of the mounting seat 2 and the bottom of the smoke oil chamber 12. In this way, the smoke oil can be prevented from leaking out from the bottom of the smoke oil chamber 12 and between the mounting seat 2, thereby ensuring the sealing performance.

[0027] For example Figure 1 and 2 As shown, the mounting seat 2 is provided with a second through hole 22a on both sides, one end of the second through hole 22a extends to the bottom of the mounting seat 2, and the other end extends to the surface of the mounting seat 2 close to the bottom surface of the heating module 3. A conductive member 27 is electrically connected between the storage battery 4 and the heating module 3, and the conductive member 27 is arranged in the second through hole 22a. Specifically, a first elastic contact is arranged at the opening of the second through hole 22a of the step surface 231 of the support seat 23, and a second elastic contact is arranged at the opening of the second through hole 22a on the bottom surface of the packaging seat 22. The conductive member 27 is connected to the first elastic contact and the second elastic contact and is accommodated in the second through hole 22a. The two electrodes 33 of the heating module 3 are electrically in contact with the two first elastic contacts respectively. The two electrode ends of the storage battery 4 are electrically in contact with the two second elastic end contacts respectively. By providing the second through hole 22a, the conductive member 27 can be prevented from being exposed, thereby achieving the purpose of ensuring the conductive member 27, preventing accidental short circuit accidents, and ensuring the stability of the device operation.

[0028] For example Figure 1 and 2 As shown, the bottom of the mounting base 2 is provided with a third through hole 22b, and the third through hole 22b is respectively communicated with the lower cavity 2a2 and the mounting cavity 13, and the mounting cavity 13 is communicated with the outside of the housing 1. By providing the third through hole 22b, when smoking, the user can inhale air into the lower cavity 2a2 through the third through hole 22b, so that the air is mixed with the atomized gas, which is conducive to enhancing the taste, and can reduce the air pressure, making it convenient to inhale.

[0029] See also Figure 1 and Figures 4 to 6, the heating module 3 includes a glass substrate 31, a conductive heating layer 32 and a pair of electrodes 33, the conductive heating layer 32 is arranged on the surface of the glass substrate 31, and the two electrodes 33 are respectively arranged at opposite ends of the surface of the conductive heating layer 32. The glass substrate 31 is provided with a plurality of first micropores 311 penetrating its surface and bottom surface, and the conductive heating layer 32 is provided with a plurality of second micropores 321 penetrating its surface and bottom surface; the first micropores 311 and the second micropores 321 are connected one by one to form the through hole 3a. The glass substrate 31 is made of materials such as silicon dioxide and silicon carbide. In this embodiment, it is made of silicon dioxide quartz glass. The conductive heating layer 32 is a thin film resistor layer, which is arranged on the surface of the glass substrate 31 by PVD sputtering. In this way, the conductive heating layer 32 can be processed more easily and the production cost can be reduced. In another embodiment, the conductive heating layer 32 is a thick film resistor layer, which is arranged on the surface of the glass substrate 31 by printing. In this way, the conductive heating layer 32 can be processed more easily and the production cost can be reduced. By using glass material as a substrate, and then setting a conductive heating layer 32 on the surface of the glass material substrate 31, and setting conductive electrodes 33 at both ends of the conductive heating layer 32, when the conductive heating layer 32 is energized through the two electrodes 33, the conductive heating layer 32 can quickly generate heat and transfer the heat to the glass material substrate 31. Micropores are opened on the surfaces of the glass material substrate 31 and the conductive heating layer 32 in a one-to-one correspondence. Therefore, when the smoke oil passes through the micropores, the glass material substrate 31 can heat and atomize the smoke oil in the micropores. Since the conductive heating layer 32 and the glass material substrate 31 have good thermal conductivity, the heat can quickly reach the micropores to heat the smoke oil, reduce heat loss, and thus greatly improve the atomization effect, and increase the battery life and service life. In addition, the combination of the glass material substrate 31 and the conductive heating layer 32 has low material cost and easy processing, so the production cost of the electronic atomization device can be reduced.

[0030] Please see again Figure 6 , the diameters of the first micropores 311 and the second micropores 321 are between 3 and 100 microns, and the spacing between two adjacent holes is between 2 and 100 microns. This arrangement can make the heat transfer faster and more uniform on the one hand, and on the other hand, it can improve the atomization ability of each micropore to the smoke oil, thereby improving the atomization effect. The thickness of the conductive heating layer 32 is between 0.1 and 500 microns. The resistance value of the conductive heating layer 32 is between 0.1 and 100 ohms. The electrode 33 is a silver paste layer, which is arranged on the surface of the conductive heating layer 32 by printing. This can make the electrode 33 easier to process and reduce production costs. Specifically, the thickness of the electrode 33 is 5 to 100 microns.

[0031] Combining the above and Figure 1 When smoking, the heating button is first activated so that the battery 4 supplies electricity to the heating module 3, and the heating module 3 generates heat to atomize the smoke oil in the through hole 3a. At this time, after inhaling from the suction nozzle 11, the gas after the smoke oil atomization enters the lower cavity 2a2, and at the same time, the outside air also enters the lower cavity 2a2 from the third through hole 22b and mixes with the gas after the smoke oil atomization. Finally, the mixed gas can be output from the smoke channel 14 to the suction nozzle 11.

[0032] Compared with the prior art, the utility model provides a heating module 3 in the mounting seat 2, so that the mounting seat 2 is divided into an upper cavity 2a1 and a lower cavity 2a2, and a plurality of through holes 3a are provided on the heating module 3, and the smoke oil cavity 12 is connected to the upper cavity 2a1, so that the smoke oil cavity 12 is connected to the through hole 3a, so that the smoke oil in the smoke oil cavity 12 can flow into the heating module 3, and the heating module 3 is powered on and heated by the battery 4, so that the smoke oil can be atomized. In addition, by connecting the lower cavity 2a2 with the through hole 3a and the suction nozzle 11, the atomized gas can be output from the suction nozzle 11 for the user to inhale. Since the heating module 3 has the advantages of uniform heating, simple structure, and simple processing technology, the electronic atomization device 100 has high heating efficiency, uniform heating, good atomization taste, low energy consumption, long battery life, long service life, and low production cost.

[0033] The above disclosure is only a preferred example of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
