[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0032] Please refer to Figures 1 to 6The utility model proposes an atomizer 100, comprising an oil storage body 11, an oil guide body 12, a heating component 13 and a PCBA board 14; wherein the oil storage body 11 is provided with an air flow channel 111 running through both ends along the axial direction; the heating component 13 is arranged in the air flow channel 111, and the heating component 13 comprises at least two heating cores 131, and each heating core 131 is at least partially in contact with the inner wall of the air flow channel 111; the oil guide body 12 is arranged between the heating component 13 and the oil storage body 11; the PCBA board 14 is arranged at the bottom of the atomizer 100 and is electrically connected to each heating core 131, and the PCBA board 14 is used to control the switch state of each heating core 131 respectively.

[0033] A plurality of heating cores 131 are arranged in the atomizer 100. Each heating core 131 can be made of a heating wire wrapped with the same or different materials, including fiber materials, hard porous materials, etc. For example, the fiber materials can be cotton fibers, glass fibers, etc., and a plurality of chambers for storing atomized liquid are formed inside the fiber materials. For example, the hard porous materials can be ceramics, polyurethane, etc., and a plurality of holes for storing atomized liquid are formed inside the hard porous materials. The oil guide body 12 connected to the heating core 131 can also be made of fiber materials, hard porous materials, etc. The oil guide body 12 is used to connect the oil storage body 11, and the atomized liquid is placed in the oil storage body 11. A channel for transmitting the atomized liquid is formed inside the oil guide body 12, so that the atomized liquid in the oil storage body 11 is transferred from the oil storage body 11 to the heating core 131 connected to the oil guide body 12.

[0034] The heating core 131 heats the received atomized liquid. The atomizer 100 is connected to the battery rod for use. The battery rod provides electrical energy for the heating wire of the atomizer 100. The heating wire generates heat for heating when it is energized. The heating wire can be a metal wire. The movement of free electrons inside the metal material improves the efficiency of heat transfer. The metal wires are interwoven in a grid shape. The form of the grid includes but is not limited to circular, diamond or square forms. The mesh metal heating unit has both rigidity and toughness, which can further ensure the contact uniformity between the oil guide body 12 and the heating element. Of course, the metal wire can be in a straight line, a wavy line or a broken line shape. It is preferably a wavy line or a broken line shape. Compared with the straight line design, the length of the heating wire is increased, and the heating efficiency of the heating wire is further improved. It can be set according to actual needs.

[0035] The metal wires of the multiple heating cores 131 can be set to different lengths. Metal wires of different lengths have different resistance values ​​and therefore have different heating powers. By adjusting the electrical connection between the battery rod and different heating units, the atomization amount of the atomizer 100 can be regulated to meet the needs of different users. In other embodiments, the heating units can also be set to the same length, but the metal materials used in the multiple heating units are different, and the different metal materials have different resistivities. Therefore, the resistance between the multiple heating units is different, and the amount of atomization generated is also different. It can be understood that the bending forms between the multiple heating units are different, and they also have different resistances, and the effects are the same, which will not be expanded here.

[0036] In this embodiment, the heating core 131 is made of ceramic material, and the oil guide body 12 is made of cotton material. The ceramic heating core 131 can provide a purer and more original taste. At the same time, the ceramic material has high heat resistance and corrosion resistance and is more durable. The ceramic heating core 131 can maintain a good working condition for a longer time, extending the service life of the atomizer 100. Uniform heating The ceramic material has good thermal conductivity and can heat the atomized liquid more evenly, making the aerosol generation more uniform and stable, which can provide a better inhalation experience and avoid overheating or overcooling of the aerosol. The ceramic heating core 131 produces less carbon deposits and coking during use, which helps to reduce the frequency of cleaning and maintenance, making the electronic atomization device more convenient and easy to use.

[0037] For different heating cores 131, different materials or different resistance values ​​will cause the aerosol generated by heating the atomized liquid to have different tastes. The utility model places multiple heating cores 131 in the same atomizer 100, and the PCBA board 14 electrically connects the multiple heating cores 131. The PCBA board 14 controls the switch state of each heating core 131 to arrange and combine them, so as to achieve the regulation of various different tastes and gears of the electronic atomization device. For example, when a smaller amount of aerosol is required, a single heating core 131 or a few heating cores 131 can be turned on, and when a larger amount of aerosol is required, all heating cores 131 or most heating cores 131 can be turned on. By controlling the switch state of different heating cores 131, the taste of the generated aerosol can also be regulated, for example, all heating cores 131 made of cotton fiber material can be turned on, or all heating cores 131 made of ceramic material can be turned on, or heating cores 131 including the above two materials can be turned on to form a combined taste.

[0038] In this embodiment, each heating core 131 is provided with a through hole 1314 along the axial direction, presenting a tubular structure, and a heating space is formed inside, and the atomized liquid in the heating core 131 is heated and mixed in the heating space to form an aerosol. The provision of the through hole 1314 is conducive to improving the atomization efficiency of the heating core 131 and enhancing the atomization degree and taste of the aerosol.

[0039] Please refer to Figure 2 In order to realize the individual control of the multiple heating cores 131 by the PCBA board 14, each heating core 131 includes at least one pin 1313 extending along the bottom of the oil storage body 11, and the PCBA board 14 is provided with at least one electrode electrically connected thereto, and each electrode is connected to at least one pin 1313, and the PCBA board 14 is used to control the switch state of each electrode separately. If the pin 1313 of the heating core 131 is directly welded to the PCBA board 14, during the assembly of the atomizer 100, the pin 1313 of the heating core 131 will be directly pulled, which may easily cause damage to the heating core 131, especially for the ceramic heating core 131, there is a risk of fragmentation. Therefore, the pin 1313 of the heating core 131 is contacted with the electrode to conduct the circuit, and the contact structure is set, which effectively eliminates the assembly risk and improves the yield rate of the atomizer 100 assembly.

[0040] Specifically, each heating core 131 includes at least two pins 1313, each electrode includes at least one main electrode 141 and at least two auxiliary electrodes 142, one pin 1313 of each heating core 131 is connected to a main electrode 141, and the remaining pins 1313 not connected to the main electrode 141 are connected to the auxiliary electrodes 142 one by one, and the PCBA board 14 is used to control the switching state of each auxiliary electrode 142 respectively.

[0041] Please refer to Figure 5 Taking this embodiment as an example, three electrodes are provided on the PCBA board 14, namely a main electrode 141 and two secondary electrodes 142, the two secondary electrodes 142 are A and B, the heating component 13 includes two heating cores 131, namely a first heating core and a second heating core, each heating core 131 is provided with two pins 1313, the two pins 1313 of the first heating core are respectively connected to the main electrode 141 and A, the two pins 1313 of the second heating core are respectively connected to the main electrode 141 and B, the main electrode 141 can be kept in an open state, when the user needs to use the first heating core, the PCBA board is controlled 14 turns on A and disconnects B. When the user needs to use the second heating core, the PCBA board 14 is controlled to turn on B and disconnect A. When the user needs to use the first heating core and the second heating core at the same time, the PCBA board 14 is controlled to turn on A and B. When the user needs to use the first heating core and the second heating core alternately, the timing program in the PCBA board 14 is controlled to turn on A and B at intervals. The first heating core and the second heating core can have different resistance values. With this setting, targeted adjustments can be made according to the actual needs of the user, thereby expanding the functional mode of the atomizer 100 and improving the applicability of the electronic atomization device.

[0042] In the present embodiment, the air flow channel 111 is opened inside the oil storage body 11, and the heating core 131 is arranged in the air flow channel 111. In order to better fix the position of the heating core 131, the atomizer 100 also includes a fixing frame 15, one side of the fixing frame 15 is connected to the bottom of the oil storage body 11, and the other side is connected to the PCBA board 14. The fixing frame 15 is penetrated by at least two mounting holes 151 for passing each heating core 131. The heating component 13 also includes at least two fixing tubes 132 that are arranged through, and each fixing tube 132 is sleeved on a heating core 131 and installed on the fixing frame 15.

[0043] The fixing frame 15 can be made of flexible materials such as silicone and rubber. The fixing frame 15 is connected to the oil storage body 11. The fixing frame 15 made of flexible materials can avoid rigid collision with the oil storage body 11, causing damage to the oil storage body 11, and playing a buffering role. At the same time, the fixing frame 15 is arranged at the bottom of the oil storage body 11. The flexible material can seal the bottom of the oil storage body 11 to prevent the mixed airflow containing atomized liquid formed in the airflow channel 111 from escaping from the bottom. The fixed tube 132 sleeved on the outside of the heating core 131 is plugged into the fixing frame 15. The fixing frame 15 provides a base for fixing the heating core 131. The fixing tube 132 limits the left and right shaking of the heating core 131 and plays a role in stabilizing the heating core 131. The fixing tube 132 and the fixing frame 15 can be integrated or detachable. The detachable setting can be in the form of snap-on, plug-in, etc., which is not limited here.

[0044] Specifically, a clamping portion 152 is protruding from the inner wall of each mounting hole 151, and a clamping groove 1321 is provided at the bottom of each fixed tube 132, and each clamping groove 1321 is connected to each clamping portion 152 in a one-to-one correspondence. The clamping portion 152 protruding from the mounting hole 151 and the clamping groove 1321 in the fixed tube 132 can effectively prevent the fixed tube 132 from rotating in the mounting hole 151, and the clamping groove 1321 opens downward and directly connects with the clamping portion 152, which is convenient for assembling the fixed tube 132 and the fixed frame 15. The mounting hole 151 also facilitates the pin 1313 of each heating core 131 to be connected to the electrode on the PCBA board 14, thereby improving the assembly efficiency of the atomizer 100.

[0045] Please refer to Figure 6In this embodiment, the atomizer 100 includes at least two oil guide bodies 12, each of which includes an annular contact portion 121 sleeved on a heating core 131 and a connecting portion 122 extending circumferentially along the contact portion 121, each connecting portion 122 is connected to the oil storage body 11, and a fixed tube 132 is sleeved on the outside of an oil guide body 12 and is provided with an avoidance hole 1322 for passing through the connecting portion 122. The oil guide body 12 can be made of cotton fiber material, and the protruding connecting portion 122 can be directly plugged into the oil storage body 11, which speeds up the oil guide efficiency, so that the amount of atomized liquid absorbed is more and the absorption is more uniform. The contact portion 121 is annularly arranged and sleeved on the outside of the heating core 131. The atomized liquid transmitted to the contact portion 121 through the connecting portion 122 is in full contact with the heating core 131, thereby improving the atomization efficiency. The contact portion 121 of the oil-conducting body 12 is arranged between the fixed tube 132 and the main body of the heating core 131. In order to facilitate the connection between the connecting portion 122 connected to the contact portion 121 and the oil storage body 11, the fixed tube 132 is provided with an avoidance hole 1322. The avoidance hole 1322 has the same cross-sectional area as the connecting portion 122. The connecting portion 122 can be a cuboid and the avoidance hole 1322 can be a rectangle.

[0046] The peripheral wall of each fixed tube 132 is provided with perforations 1323 arranged at intervals with the avoidance holes 1322. During the installation process, the heating core 131 which has been sleeved with the oil-conducting body 12 slides into the fixed tube 132, and the connecting portion 122 slides into the avoidance hole 1322. The oil-conducting body 12 compresses the air in the fixed tube 132, causing the air pressure in the fixed tube 132 to increase, and the heating core 131 equipped with the oil-conducting body 12 has difficulty entering the fixed tube 132 due to the air pressure resistance. The perforations 1323 can connect the fixed tube 132 with the external atmosphere, achieve the balance of air pressure inside and outside the fixed tube 132, and facilitate the heating core 131 equipped with the oil-conducting body 12 to enter the fixed tube 132. Preferably, the perforations 1323 formed on the fixed tube 132 can be symmetrically arranged to form a gas channel, which is conducive to pressure relief during the installation process.

[0047] Please refer to Figure 3 and Figure 4 The atomizer 100 includes at least two air pipes 16 disposed inside the oil storage body 11 and connected to the external atmosphere. The interior of each air pipe 16 forms a partial area of ​​the air flow channel 111. The inner wall of one end of each air pipe 16 close to the heating component 13 is connected to a heating core 131. An air pipe 16 is provided for each heating core 131, and the multiple air pipes 16 are not directly connected, which can effectively reduce the transmission path of the aerosol. The air pipe 16 is connected to the through hole 1314 of the heating core 131, so that the aerosol generated by heating can directly enter the air pipe 16, and the aerosol is isolated from entering the oil storage body 11. The aerosol flows out from the air nozzle at the top of the atomizer 100.

[0048] In this embodiment, each air pipe 16 is a glass fiber tube. The glass fiber tube has low cost and is easy to assemble. The glass fiber tube can be cut to length according to the height of the oil storage body 11. Each air pipe 16 is arranged inside or outside a fixed pipe 132. When the air pipe 16 is sleeved outside the fixed pipe 132, the air pipe 16 can be provided with an avoidance hole 1322 corresponding to the connecting portion 122 of the oil guide body 12, which has the same shape as the avoidance hole 1322 of the fixed pipe 132.

[0049] Please refer to Figure 1 When the air pipe 16 is sleeved inside the fixed pipe 132, each heating core 131 includes a first portion 1311 close to the bottom of the oil storage body 11 and a second portion 1312 facing the top of the oil storage body 11, the diameter of the first portion 1311 is larger than the second portion 1312, each oil guide body 12 is sleeved on the first portion 1311 of a heating core 131, and each air pipe 16 is sleeved on the second portion 1312 of a heating core 131 and abuts against the end face of the first portion 1311. The difference in diameter between the first portion 1311 and the second portion 1312 should not be too large, and the air pipe 16 abutting against the end face of the first portion 1311 can enhance the airtightness between the two and prevent the aerosol generated by the heating of the atomized liquid from escaping. The larger diameter of the first portion 1311 can enhance the contact pressure between the oil guide body 12 and the oil storage body 11, which is beneficial for the oil guide body 12 to absorb the atomized liquid in the oil storage body 11. The second portion 1312 with a smaller diameter and the oil storage body 11 enclose an installation space for placing the air supply pipe 16.

[0050] In this embodiment, a bracket 143 is installed on the side of the PCBA board 14 facing the fixing frame 15, and a plug-in portion is convexly provided on the side of the bracket 14 facing away from the PCBA board 14, and a plug-in slot is concavely provided on the side of the fixing frame 15 facing the PCBA board 14, and the plug-in portion is plug-fitted with the plug-in slot.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
