Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to an atomizer and a manufacturing method thereof, and an electronic cigarette. Background Art

[0002] Electronic cigarettes, also known as virtual cigarettes, steam cigarettes, and aerosol-generating devices, primarily heat the e-cigarette's internal e-liquid or e-paste to produce an aerosol for the user to inhale. The e-liquid typically contains nicotine salts, and the heated aerosol contains nicotine but is free of harmful substances like tar and carbon monoxide, offering users a healthy alternative to cigarettes.

[0003] Existing e-cigarettes consist of an atomizer and a battery. The core component of the atomizer is the atomizer core assembly, which typically includes an oil guide and a heater. The oil guide is used to transport the e-liquid, while the heater is used to heat the e-liquid in the oil guide to produce an aerosol. Currently, the atomizer core assembly in atomizers is mostly composed of a porous ceramic core, and the heater is mostly an etched sheet (or heating wire). To ensure a tight connection between the porous ceramic core and the heater, the atomizer core assembly is usually made by printing electronic paste on a ceramic substrate or embedding a metal heater and sintering it. Since sintering is used, a larger diameter metal heater is required. The embedded metal heater blocks some of the micropores of the porous ceramic core, causing the e-liquid inside the pores to circulate and heat without being atomized, resulting in a sticky core and a poor taste.

[0031] like Figures 1 to 8 As shown, an atomizer provided by the present invention includes an oil storage shell 10, an atomization bin shell 20 and an atomization core assembly 30. The oil storage shell 10 is provided with an oil storage cavity 101, and the atomization bin shell 20 is provided with an atomization bin 201. The oil storage cavity 101 and the atomization bin 201 are connected to each other. The atomization core assembly 30 is arranged at the connection between the oil storage cavity 101 and the atomization bin 201. The atomization core assembly 30 includes a porous ceramic 31, a heating net 32, a fixing bracket 33 and an elastic gasket 34. The heating net 32 is fixed on the fixing bracket 33. The porous ceramic 31 is clamped between the heating net 32 and the elastic gasket 34. The elastic gasket 34 is located at the edge of the porous ceramic 31.

[0032] In the present application, a fixing bracket 33 is provided to fix the heating network 32, and the porous ceramic 31 is clamped between the heating network 32 and the elastic gasket 34. The porous ceramic 31 and the heating network 32 are tightly fitted under the clamping of the fixing bracket 33 and the elastic gasket 34, so there is no need to use a sintering process to make the porous ceramic 31 and the heating network 32 tightly connected, avoiding the metal of the heating network 32 being embedded in the micropores of the porous ceramic 31 and blocking part of the micropores during sintering, causing the core to become sticky and affecting the taste; therefore, the production and assembly process of the atomizer in the present application is simple and the cost is very low.

[0033] In this embodiment, Figure 3 As shown, the oil storage shell 10 is arranged in the atomizing chamber shell 20, and the oil storage shell 10 is provided with an oil filling port 102 ( Figure 7), the oil storage chamber 101 is connected to the atomization bin 201 through the oil filling port 102, and the atomization core assembly 30 is located in the atomization bin 201 and docked with the oil filling port 102. Among them, the oil filling port 102 is located at the bottom of the oil storage shell 10, so that the smoke oil is injected downward into the cavity of the atomization core assembly 30 under the action of gravity, and then flows to the heating network 32 and begins to atomize. Specifically, the size of the elastic gasket 34, the size of the oil filling port 102 and the size of the porous ceramic 31 match each other, and the elastic gasket 34 is interference fit with the oil filling port 102 and the porous ceramic 31 respectively. The elastic gasket 34 is located at the oil filling port 102 and is clamped between the oil storage shell 10 and the porous ceramic 31, and the bottom of the fixed bracket 33 is connected to the atomization bin shell 20. When the oil reservoir 10 is installed in the atomizer housing 20, the entire atomizer core assembly 30 is squeezed by the oil reservoir 10 and the atomizer housing 20. The use of the elastic gasket 34 ensures a tight connection between the porous ceramic 31 and the heating grid 32. Of course, in other embodiments, the atomizer housing 20 can also be located within the oil reservoir 10, while the oil filling port 102 needs to be located on the atomizer housing 20, and the bottom of the fixing bracket 33 is connected to the oil reservoir 10.

[0034] Further, if Figure 3 、 Figure 5 as well as Figure 7 As shown, the atomizer is provided with a flue 103 communicating with the atomizing chamber 201. The flue 103 is located at the edge of the oil storage chamber 101. In this embodiment, the flue 103 is provided at the edge of the oil storage housing 10, and the flue 103 and the oil storage housing 10 are integrated into a one-piece structure. Of course, in other embodiments, the flue 103 can also be integrated into the atomizing chamber housing 20.

[0035] Specifically, if Figure 3 、 Figure 5 as well as Figure 7 As shown, the atomizer shell 20 includes a base 21 and an outer shell 22 connected to the base 21. The base 21 and the oil storage shell 10 together form an atomizer 201. The outer shell 22 is a tubular structure. The outer shell 22 is provided with a receiving hole 202 for installing the oil storage shell 10, and the oil storage shell 10 is fixed in the receiving hole 202. The flue 103 is located on both sides of the oil storage cavity 101, and the flue 103 is integrated with the oil storage shell 10, so that the atomized gas can be quickly discharged. In addition, the flue 103 is integrated with the oil storage shell 10 and is away from the heating network 32. To a certain extent, it can reduce the temperature of the atomized gas, avoid the temperature of the smoke being too high, and give the smoker a good taste. Among them, the oil storage shell 10 and the atomizer shell 20 are both rectangular structures as a whole. Of course, in order to increase the user's grip, they can also be designed into other shapes.

[0036] Furthermore, the base 21 is provided with a plurality of air inlet holes 203 that are in communication with the atomizing chamber 201. The plurality of air inlet holes 203 are distributed in a straight line and are located at the bottom of the atomizing core assembly 30, so that air can quickly enter the atomizing chamber 201 and quickly discharge the atomized smoke. Figure 5 and Figure 7 As shown, there are three air inlet holes 203 , and the diameter of the middle air inlet hole 203 is larger than the diameters of the air inlet holes 203 at both ends.

[0037] like Figure 4 、 Figure 6 as well as Figure 8 As shown, the heating network 32 is provided with an electrode sheet 322, and the base 21 is provided with an electrode column 211 electrically connected to the electrode sheet 322, as well as a mounting hole 204 for mounting the electrode column 211. One end of the electrode sheet 322 is electrically connected to the heating network 32, and the other end of the electrode sheet 322 is connected to the electrode column 211. The end of the electrode column 211 away from the electrode sheet 322 is exposed on the outer surface of the base 21. It can be understood that the electrode sheet 322 and the electrode column 211 both include a positive electrode and a negative electrode to respectively connect the heating network 32 to the positive and negative poles of the power supply. The electrode sheet 322 is connected to the edge of the heating network 32.

[0038] In this embodiment, Figure 4 、 Figure 6 as well as Figure 8 As shown, the edge of the heating net 32 is provided with a connecting portion 321, and the connecting portion 321 is provided at both ends of the heating net 32. The fixing bracket 33 includes a supporting frame 331 and a mounting portion 332 that are connected to each other. The mounting portion 332 is provided at both ends of the supporting frame 331 and corresponds to the connecting portion 321. The mounting portion 332 is provided with a card slot 332a that cooperates with the connecting portion 321, and the connecting portion 321 is clamped in the card slot 332a. Among them, the fixing bracket 33 is a frame structure, so that the smoke heated and atomized by the heating net 32 can quickly enter the atomization chamber 201 and be fully discharged from the flue 103. The mounting portion 332 is also provided with a through hole 332b ( Figure 8 ), the through hole 332b is connected to the card slot 332a, and one end of the electrode sheet 322 passes through the through hole 332b and is conductively connected to the connecting portion 321 of the heating network 32.

[0039] Furthermore, the atomizer core assembly 30 includes a gasket 35 that cooperates with the connecting portion 321. The gasket 35 and the connecting portion 321 overlap with each other and are both clamped in the clamping groove 332a. By arranging the gasket 35 in the clamping groove 332a, the installation firmness of the heating network 32 and the fixing bracket 33 can be increased.

[0040] Furthermore, a sink 311 is provided on the outer edge of the porous ceramic 31. The sink 311 is an annular structure. The elastic gasket 34 is provided in the sink 311, so as to facilitate the installation of the elastic gasket 34 and increase the sealing between the porous ceramic 31 and the oil filling port 102 of the oil storage shell 10. Among them, the gasket 35 and the elastic gasket 34 are both made of insulating, heat-insulating and high-temperature resistant materials, such as silicone. The elastic gasket 34 is used to make it possible to fit the heating net 32 and the porous ceramic 31 more closely together under the support of the fixed bracket 33, thereby ensuring that the heating net 32 can more fully atomize the smoke oil derived from the porous ceramic 31, and also avoid the risk of the heating net 32 and the porous ceramic 31 being burned due to not being tightly fitted.

[0041] Furthermore, the outer edge of the elastic gasket 34 is provided with a flange 341, i.e., the longitudinal cross-section of the elastic gasket 34 is L-shaped. The flange 341 is annular and partially protrudes from the outer surface of the porous ceramic 31. The flange 341 can mate with the bottom wall of the oil reservoir 10 at the edge of the oil filling port 102, thereby further ensuring a tight fit between the heating network 32 and the porous ceramic 31 and enhancing the sealing between the porous ceramic 31 and the oil filling port 102 of the oil reservoir 10.

[0042] Specifically, the outer edge of the oil filling port 102 of the oil reservoir housing 10 is provided with a raised ring 11 that mates with the sunken platform 311. An elastic washer 34 is sandwiched between the sunken platform 311 and the raised ring 11. A flange 341 is sandwiched between the top wall of the sunken platform 311 and the bottom wall of the raised ring 11. After the oil reservoir housing 10 is installed in the atomizer housing 20, the entire atomizer core assembly 30 is squeezed by the oil reservoir housing 10 and the atomizer housing 20, causing the porous ceramic 31 and the raised ring 11 of the oil reservoir housing 10 to press against the elastic washer 34, thereby improving the sealing between the porous ceramic 31 and the oil filling port 102 of the oil reservoir housing 10. Among them, the outer diameter of the porous ceramic 31 at the sink 311 is slightly larger than or equal to the inner diameter of the elastic washer 34, and the outer diameter of the elastic washer 34 at the vertical part is slightly larger than or equal to the inner diameter of the oil filling port 102, the outer diameter of the flange 341 is slightly larger than or equal to the outer diameter of the convex ring 11, and the inner diameter of the convex ring 11 is the same as the inner diameter of the oil filling port 102.

[0043] In the present embodiment, the shape of the porous ceramic 31 is a semi-hollow cylindrical structure, the shape of the heating net 32 is a semi-circular tube structure, and the heating net 32 is attached to the outer side wall of the porous ceramic 31. By setting the shape of the porous ceramic 31 to a semi-hollow cylindrical structure and the shape of the heating net 32 to a semi-circular tube structure, the oil filling speed can be increased, and the atomization contact area can be maximized, the smoke oil can be atomized in time, the atomization efficiency is high, and the atomization amount is large. Of course, the shape of the heating net 32 can also be a semi-hollow cylindrical structure, but the size of the heating net 32 is slightly larger than the size of the porous ceramic 31, so that the heating net 32 can be closely attached to the outer side wall of the porous ceramic 31. Among them, the heating net 32 can be woven with a flexible resistance wire, and the porous ceramic 31 is fired by the original sintering ceramic process.

[0044] The present invention also provides a method for manufacturing an atomizer, which is used to manufacture the atomizer as described above, and the method comprises:

[0045] First, the porous ceramic 31 and the heating net 32 are separately manufactured. Specifically, the heating net 32 can be woven with flexible resistance wire, and the porous ceramic 31 is fired by the original sintering ceramic process, that is, the porous ceramic 31 and the heating net 32 are separately manufactured by different processes.

[0046] A fixing bracket 33 and an elastic washer 34 are provided, and the heating net 32 is fixed on the fixing bracket 33. The elastic washer 34 is sleeved on the porous ceramic 31. The elastic washer 34 is located at the edge of the porous ceramic 31. The porous ceramic 31 is then installed on the heating net 32. The porous ceramic 31 is clamped between the heating net 32 and the elastic washer 34, so that the porous ceramic 31 and the heating net 32 are tightly connected.

[0047] The atomizer also includes an oil storage shell 10 and an atomization chamber shell 20. When the atomization core assembly 30 is assembled with the oil storage shell 10 and the atomization chamber shell 20, the atomization core assembly 30 is clamped between the oil storage shell 10 and the atomization chamber shell 20. Under the pressure of the oil storage shell 10 and the atomization chamber shell 20, the porous ceramic 31 and the heating net 32 are tightly squeezed together due to the use of an elastic gasket 34.

[0048] In this embodiment, the oil storage shell 10 is arranged in the atomizing chamber shell 20, and the oil storage shell 10 is provided with an oil filling port 102 ( Figure 7), the oil storage chamber 101 is connected to the atomization bin 201 through the oil filling port 102, and the atomization core assembly 30 is located in the atomization bin 201 and docked with the oil filling port 102. Among them, the oil filling port 102 is located at the bottom of the oil storage shell 10, so that the smoke oil is injected downward into the cavity of the atomization core assembly 30 under the action of gravity, and then flows to the heating network 32 and begins to atomize. Specifically, the size of the elastic gasket 34, the size of the oil filling port 102 and the size of the porous ceramic 31 match each other, and the elastic gasket 34 is interference fit with the oil filling port 102 and the porous ceramic 31 respectively. The elastic gasket 34 is located at the oil filling port 102 and is clamped between the oil storage shell 10 and the porous ceramic 31, and the bottom of the fixed bracket 33 is connected to the atomization bin shell 20. When the oil reservoir 10 is installed in the atomizer housing 20, the entire atomizer core assembly 30 is squeezed by the oil reservoir 10 and the atomizer housing 20. The use of the elastic gasket 34 ensures a tight connection between the porous ceramic 31 and the heating grid 32. Of course, in other embodiments, the atomizer housing 20 can also be located within the oil reservoir 10, while the oil filling port 102 needs to be located on the atomizer housing 20, and the bottom of the fixing bracket 33 is connected to the oil reservoir 10.

[0049] In the present application, the porous ceramic 31 and the heating net 32 are manufactured separately, and a fixing bracket 33 is provided for fixing the heating net 32, and then the porous ceramic 31 is clamped between the heating net 32 and the elastic gasket 34. The porous ceramic 31 and the heating net 32 are tightly fitted under the clamping of the fixing bracket 33 and the elastic gasket 34, so that there is no need to use a sintering process to make the porous ceramic 31 and the heating net 32 tightly connected, avoiding the metal of the heating net 32 being embedded in the micropores of the porous ceramic 31 and blocking part of the micropores during sintering, causing the core to become sticky and affecting the taste; therefore, the production and assembly process of the atomizer in the present application is simple and the cost is very low.

[0050] The present invention also provides an electronic cigarette comprising a mouthpiece 40 and the aforementioned atomizer, wherein the mouthpiece 40 is connected to the atomizer. The mouthpiece 40 is provided with an air intake hole 401, which is connected to the flue 103, thereby allowing smoke to be drawn out through the flue 103. The electronic cigarette also includes a battery and a control chip. The battery is used to provide power to the atomizer, and the control chip is used to control the battery to provide power to the atomizer, thereby controlling the amount of atomization produced by the atomizer.
