Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of atomizer, in particular to an atomization device and an atomization assembly thereof. BACKGROUND

[0002] In order to realize the heating and atomization effect, the existing ceramic heating atomization device usually prints a layer of conductive paste on the surface of the ceramic to form a heating circuit based on the screen printing process. Because the printed heating circuit is located on the surface of the atomization core, the heating circuit is in full contact with the smoke liquid and smoke gas during the atomization process, which is easy to cause corrosion and fracture of the circuit, and the direct contact process will cause the local high temperature of the heating circuit to decompose harmful substances from the atomization matrix, which affects human health. At the same time, due to the limitations of the printing process itself, the heating electrode prepared by this method has the disadvantages of high local electrode circuit temperature, poor controllability of electrode circuit quality, and poor service life.

[0003] Therefore, in Chinese patent CN104872821A, an atomization core for an electronic cigarette is disclosed, which separates the atomization matrix from the oil guide medium to solve the corrosion problem of the electric heating component immersed in the atomization matrix for a long time. However, in this scheme, the electric heating circuit is difficult to be processed on the inner wall of the atomization chamber, and the circuit is difficult to be connected out, which has poor assembly and sealing performance in production. In the prior art, physical vapor deposition processes (PVD) such as vacuum evaporation coating, vacuum sputtering coating, and vacuum ion coating are also used to precisely form the heating circuit on the surface of the ceramic. However, this technology has complex production equipment, high production cost, low yield, and low efficiency, and is not suitable for mass production of ordinary consumer electronics. Directly using conductive ceramic with high electrical conductivity to form a porous conductive atomization device, because the existing conductive ceramic material has a significantly lower thermal conversion efficiency than metal material, a higher power supply output is needed to achieve the same heating and atomization effect, and the better the conductivity of the conductive ceramic, the worse the strength. Therefore, there is an urgent need for an atomization assembly that can solve the above problems. SUMMARY

[0027] Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment can be included in at least one embodiment of the application. The appearance of the phrase in various places in the specification does not necessarily all refer to the same embodiment, nor is it necessarily mutually exclusive of other embodiments. It is explicitly and implicitly understood that the embodiments described herein can be combined with other embodiments.

[0028] The present application provides an atomization assembly, please refer to Figure 1 , Figure 1 is a perspective view of an embodiment of the atomization assembly of the present application. The atomization assembly in the embodiment includes but is not limited to a packaging shell 110, an atomization core 120, and an electromagnetic induction piece 130. The atomization core 120 is entirely wrapped inside the packaging shell 110, and the electromagnetic induction piece 130 is located inside the atomization core 120. Wrapping the outside of the atomization core 120 entirely inside the packaging shell 110 can not only improve the overall strength of the atomization device, but also prevent random overflow and drift of the atomization substrate during the atomization process, making the atomization smoke advance more smoothly and enhancing the sealing of the device.

[0029] Specifically, please refer to Figure 2 and Figure 3 , Figure 2 is Figure 1 is a sectional view of the packaging shell of the atomization assembly shown in Figure 3 is Figure 1A cross-sectional structure diagram of an atomization core of the atomization assembly. The packaging shell 110 includes a first end portion 111 and a second end portion 112 arranged oppositely, the first end portion 111 is provided with an air vent 11101, and the second end portion 112 is provided with an oil inlet 11201. The packaging shell 110 is made of non-conductive and non-oil-conductive material, and the material of the packaging shell 110 is polypropylene plastic or polycarbonate plastic. The aerosol formed by atomization in the atomization assembly can diffuse outward from the air vent 11101 of the first end portion 111, and the atomization substrate outside the atomization assembly can enter the atomization assembly from the oil inlet 11201 of the second end portion 112.

[0030] The atomization core 120 includes a first surface 121 and a second surface 122, the first surface 121 is close to the first end portion 111 of the packaging shell 110, and the second surface 122 is close to the second end portion 112 of the packaging shell 110. The material of the atomization core 120 is a porous material with excellent oil conductivity, and the material of the atomization core 120 is a porous ceramic. The porous ceramic has many small micropores inside, which have stable liquid guiding and locking functions. Due to surface tension and capillary action, the atomization substrate entering the atomization assembly through the oil inlet 11201 can uniformly penetrate into the micropores of the atomization core 120 and be adsorbed on the surface of the atomization core 120. The electromagnetic induction piece 130 generates a large amount of heat in the working state, so that the temperature of the atomization core 120 rises rapidly to 200-300℃, reaches the atomization temperature of the atomization substrate, and the aerosol formed by atomization of the atomization substrate in the atomization core 120 diffuses from the pores of the porous ceramic to the first surface 121 of the atomization core 120, and then passes through the air vent 11101 to the outside of the atomization assembly, so that the atomization substrate is heated more uniformly during atomization, and the atomization is more sufficient per unit time, with higher atomization efficiency.

[0031] Optionally, the atomization core 120 is internally provided with a heating through slot 1201, the heating through slot 1201 penetrates through the atomization core 120 and communicates the first surface 121 and the second surface 122. The electromagnetic induction piece 130 is substantially cylindrical and located inside the heating through slot 1201. The heating through slot 1201 is in the shape of a circular truncated cone, and the radius of the cross section gradually decreases along the normal direction from the first surface 121 to the second surface 122, so that the part of the heating through slot 1201 close to the oil inlet 11201 is far away from the electromagnetic induction piece 130 and has a lower temperature, and the part of the heating through slot 1201 close to the air vent 11101 is close to the electromagnetic induction piece 130 and has a higher temperature, forming a temperature difference to make the aerosol advance more smoothly and improve the atomization efficiency.

[0032] The second end 112 of the packaging shell 110 is also provided with an inductor base 1121 and a sensor base 1122, which are designed in an integrated manner to facilitate external connection and packaging, and enhance the assembly of the atomization assembly. The inductor base 1121 and the sensor base 1122 are made of a material with electrical conductivity, which is used to electrically connect or transmit signals with an external circuit. Alternatively, the inductor base 1121 and the sensor base 1122 can be made of copper, nickel or other metals. Further, the electromagnetic induction piece 130 includes an inductor coil 131 and a heating column 132. The heating column 132 is located inside the inductor coil 131, and the inductor base 1121 is located in the heating through slot 1201 and electrically connected to the inductor coil 131. The inductor coil 131 is connected to a conductive communication part 140, as shown in Figure 4 Figure 4 Figure 1 The structure diagram of the conductive communication part and the inductor coil of the atomization assembly is shown in

[0033] The heating column 132 is connected to an insulating end 160 at both ends, as shown in Figure 5 Figure 5 Figure 1 The structure diagram of the heating column and the insulating end of the atomization assembly is shown in

[0034] Alternatively, the material of the heating column 132 can be iron, cobalt, nickel or other metals, or an alloy containing at least one of iron, cobalt, nickel, or a conductive non-metallic material such as a carbon rod, graphite material, a certain size of carbon fiber / nanotube, and silicon carbide material. The above-mentioned materials have high magnetic permeability and electrical conductivity, which is beneficial to rapid heating and heat conduction. The material of the insulating end 160 can be silicone, epoxy resin, or other polymers with high thermal conductivity and high electrical insulation. The heating column 132 and the insulating end 160 are designed independently, which can be manufactured separately from other components of the atomization assembly, facilitating mass production and production control, and improving the production and assembly efficiency of the entire device.

[0035] ​​​​Optionally, the conductive communication part 140 is in the shape of a circular ring structure, fixedly connected with the first surface 121 of the atomization core 120. In some other embodiments, the conductive communication part 140 can also be in the shape of a hollow square, a hollow triangle, a straight line, a zigzag connecting block or the like structure, as long as it can form a loop with the external circuit for the inductive coil 131 and shield the air inlet 11101 as little as possible. Those skilled in the art can make any adjustment according to the assembly design requirements, which will not be listed and described one by one here.

[0036] When the inductive coil 131 flows through high-frequency alternating current, an alternating magnetic field is generated around the inductive coil 131 and a magnetic flux is generated, which in turn causes the heating column 132 in the inductive coil 131 to generate an induced electromotive force, so that eddy current flows through the heating column 132. Due to the Joule effect, part of the energy is dissipated in the form of heat. The heat generated by the heating column 132 under the action of electromagnetic induction is conducted to the heating through slot 1201 of the atomization core 120 through the air and the insulating end 160. The heat rapidly spreads along the heating through slot 1201 to the entire atomization core 120, generating a high temperature of 200-300℃, which atomizes the atomization substrate into an aerosol to generate an aerosol. The heating column 132 does not directly contact the atomization core 120, avoiding the phenomenon of local dry burning caused by excessive concentration of heating points in the existing resistance wire heating method, which produces harmful substances and heat that is not easy to diffuse, thereby improving the heating efficiency, aerosol quality and service life of the atomization assembly.

[0037] In the present embodiment, the number of the heating through slot 1201, the inductive coil 131, the heating column 132 and the inductive base 1121 is 2. In some other embodiments, the number of the heating through slot 1201 can be one or more, and the shape of the heating through slot 1201 can be a cylinder, a cuboid or a triangular prism, etc. The number and shape of the heating through slot 1201 can be adjusted arbitrarily according to the atomization efficiency requirement of the atomization substrate. The number of the inductive coil 131, the heating column 132 and the inductive base 1121 only needs to be designed in matching with the heating through slot 1201, which will not be specifically limited here.

[0038] Optionally, as shown in Figure 3 The inside of the atomization core 120 is provided with an oil immersion groove 1202, which is connected with the second surface 122 and located in the normal projection area of the oil inlet 11201 of the packaging shell 110. The external atomization substrate can enter the oil immersion groove 1202 through the oil inlet 11201, and the atomization substrate contacts the inner wall of the oil immersion groove 1202 and is adsorbed into the whole atomization core 120 under the action of capillary adsorption. The oil immersion groove 1202 increases the contact area between the atomization core 120 and the external atomization substrate, improves the contact efficiency and adsorption efficiency, and further improves the atomization efficiency.

[0039] Optionally, in combination with Figures 1-3The atomization core 120 is internally provided with a temperature measuring groove 1203, and the temperature measuring groove 1203 is connected to the side of the oil immersion groove 1202 away from the second end portion 112. The atomization assembly further comprises a temperature sensor 150, which is located in the temperature measuring groove 1203 and detects the temperature of the atomization core 120 in real time, directly and accurately detects the actual temperature of the atomization position, and improves the temperature control accuracy. The sensor base 1122 of the packaging shell 110 is connected to the temperature sensor 150 through the oil immersion groove 1202, and provides current and transmits information for the temperature sensor 150.

[0040] Please refer to Figure 6 , Figure 6 is Figure 1 the assembly and exploded view of the atomization assembly shown. The packaging shell 110 of the atomization assembly is wrapped outside the atomization core, avoiding the random drift and overflow of the atomization matrix during the atomization process. The inductor coil 131 of the electromagnetic induction piece 130 is connected to the inductor base 1121, and when energized, the heating column 132 inside the inductor coil 131 generates high temperature under the action of electromagnetic induction, so that the overall temperature of the atomization core 120 rapidly rises to 200-300℃, reaching the atomization temperature of the atomization matrix. After the atomization matrix in the atomization core 120 is atomized, the atomization matrix in the oil immersion groove 1202 is continuously adsorbed and supplemented into the atomization core 120 under the capillary adsorption force of the porous material, so that the atomization matrix is continuously atomized into aerosol.

[0041] Further, the present application also provides an atomization device, please refer to Figure 7 , Figure 7is a structural diagram of an embodiment of the atomization device. The atomization device in this embodiment includes an atomization assembly 10, an oil storage tank 20, a control unit 30, a battery 40, a gas guide pipe 50, and a suction nozzle 60. The atomization assembly 10 includes the packaging shell 110, the atomization core 120, the electromagnetic induction piece 130, and the temperature sensor 150 of the above-mentioned embodiments. The atomization assembly 10 is located inside the oil storage tank 20. The atomization substrate in the oil storage tank 20 enters the oil immersion groove 1202 of the atomization core 120 from the oil inlet 11201 of the packaging shell 110. The atomization substrate in the oil immersion groove 1202 is adsorbed into the atomization core 120 under the capillary adsorption force of the porous ceramic. The control unit 30 controls the output of the battery 40 to provide alternating current for the inductor coil 131 of the electromagnetic induction piece 130, so that the inductor coil 131 generates an alternating electric field, the heating column 132 generates eddy current in the alternating electric field, the atomization substrate in the atomization core 120 generates aerosol, the atomization substrate in the oil immersion groove 1202 is continuously adsorbed and supplemented into the atomization core 120, so that the atomization substrate is continuously atomized, the aerosol reaches the air vent 11101 of the packaging shell 110 through the pores of the porous ceramic, the gas guide pipe 50 is located between the air vent 11101 and the suction nozzle 60 and is in close contact with the air vent 11101 and the suction nozzle 60, and is used for guiding the aerosol from the air vent 11101 to the suction nozzle 60. The aerosol is then taken or diffused to the outside by the suction nozzle 60.

[0042] Further, the application also provides a temperature control method applied to the atomization device, which includes the atomization assembly 10, the control unit 30, and the battery 40 of the above-mentioned embodiments. The temperature control method includes the following steps:

[0043] The temperature sensor 150 located in the temperature measurement groove 1203 detects the internal temperature of the atomization core 120 in real time and feeds back the temperature data to the external control unit through the sensor base 1122. The control unit controls the power supply of the electromagnetic induction piece from the battery 40 according to the detected temperature data. If the temperature data is lower than the temperature range of the atomization substrate, the alternating current intensity of the inductor coil 131 surrounding the heating column 132 is increased to increase the heating power of the heating column 132. If the temperature data is higher than the temperature range of the atomization substrate, the alternating current intensity of the inductor coil 131 is reduced to reduce the heating power of the heating column 132, so that the internal temperature of the atomization core 120 is stabilized within the temperature range of the atomization substrate.

[0044] The atomization assembly provided by the application has the electromagnetic induction piece built in the atomization core and the atomization core wrapped in the packaging shell. The electromagnetic induction heating and temperature control improve the heating efficiency, production and assembly efficiency, and service life of the atomization assembly, and enhance the sealing performance of the device and the quality of the aerosol.
