[0046] Specifically, the first electrical connection port 115 is used to provide a connection channel for the electrical connection between the heating element 130 and the power supply of the atomizing device body 200. The heating element 130 can be directly electrically connected to the positive and negative poles 140 of the power supply. In this case, the first electrical connection port 115 is used for the positive and negative poles 140 of the power supply to pass through, and the positive and negative poles 140 of the power supply are electrically connected to the heating element 130 after passing through the corresponding first electrical connection port 115; of course, the heating element 130 can also be electrically connected to the positive and negative poles 140 of the power supply through the positive and negative pole pins fixedly provided on it. In this case, the first electrical connection port 115 can be used for the positive and negative pole pins of the heating element 130 to pass through, and the positive and negative pole pins are electrically connected to the positive and negative poles 140 of the power supply after passing through the corresponding first electrical connection port 115. The position and number of the first electrical connection port 115 can be set as needed, and are not limited here.

[0047] Specifically, the liquid-conducting member 120 may be configured as oil-conducting cotton, and the oil-conducting cotton may be made of one or more materials selected from organic cotton sheets, wood pulp cotton cloth, fiber cotton cloth, linen cloth, and the like.

[0048] The atomizer core 100 provided in this embodiment has a modular design, which can simplify the production and assembly process of the atomizer device and improve production efficiency. The atomizer core 100 can be detachably plugged into the atomizer device body 200, so that when one of the atomizer core 100 and the atomizer device body 200 is damaged or reaches the end of its service life, the part that needs to be replaced can be replaced separately, while other parts that can continue to be used are retained, thereby improving the utilization rate of the entire atomizer device 300 and saving resources.

[0049] In another embodiment of the present application, please refer to Figure 4 The positioning and mounting portion 116 is configured as a first slot 1161 or a first elastic protrusion (not shown).

[0050] Specifically, when the positioning and mounting portion 116 of the atomizer core 100 is set as a first card groove 1161, the atomizer core 100 can cooperate with the atomizer device body 200 provided with a second elastic protrusion 2144, and the cooperation between the first card groove 1161 and the second elastic protrusion 2144 can make the atomizer core 100 and the atomizer device body 200 detachably plugged; when the positioning and mounting portion 116 of the atomizer core 100 is set as a first elastic protrusion, the atomizer core 100 can cooperate with the atomizer device body 200 provided with a second card groove (not shown in the figure), and the cooperation between the first elastic protrusion and the second card groove can make the atomizer core 100 and the atomizer device body 200 detachably plugged.

[0051] In another embodiment of the present application, please refer to Figure 2 The first air inlet 112 and the first air outlet 113 are both disposed at the top of the fixing assembly 110. With the atomizer core 100 of the above structure, the possibility of atomized liquid in the inner cavity 111 leaking through the first air inlet 112 or the first air outlet 113 at the top is small, and the risk of liquid leakage is low.

[0052] Optionally, the first air inlet 112 and the first air outlet 113 are arranged on opposite sides of the fixed component 110, so that the air entering the inner cavity 111 from the first air inlet 112 will flow through the entire heating element 130 and then flow out from the second air outlet 113, which is conducive to completely taking away the aerosol generated by the heating element 130.

[0053] In another embodiment of the present application, please refer to Figure 2 and Figure 3 The outer surface of the fixing assembly 110 is also provided with a guide groove 119 extending along the insertion direction. The atomizer core 100 with the above structure can cooperate with the atomizer device body 200 provided with a guide block 2146. The guide groove 119 cooperates with the guide block 2146 to guide the atomizer core 100 to be inserted into the insertion groove 214 of the atomizer device body 200 along the insertion direction.

[0054] In another embodiment of the present application, please refer to Figure 6 The heating element 130 and the liquid guiding element 120 are laid flat and stacked in the inner cavity 111. With the atomizer core 100 having the above structure, the atomized liquid in the liquid guiding element 120 can be efficiently transmitted to the heating element 130, which can ensure that the heating element 130 has a larger effective atomization area, thereby improving the atomization effect.

[0055] In another embodiment of the present application, please refer to Figure 2 and Figure 3The fixing assembly 110 includes an upper cover 117 and a lower cover 118 for enclosing an inner cavity 111. The upper cover 117 is provided with a first liquid guide port 114. The heating element 130 is fixedly connected to the upper cover 117 or the lower cover 118. The liquid guide element 120 is sandwiched between the upper cover 117 and the heating element 130 or between the heating element 130 and the lower cover 118.

[0056] Specifically, the lower cover 118 of the upper cover 117 can be fixedly connected in a variety of ways, such as threaded connection, snap connection, etc., and can be configured as needed, which is not limited here.

[0057] Specifically, the heating element 130 can be fixedly connected to the upper cover 117 or the lower cover 118 in a variety of ways. For example, when the heating element 130 is fixedly connected to the upper cover 117, the heating element 130 can be fixedly connected to the upper cover 117 by screws 1323. For another example, the heating element 130 can be clamped and fixed by the upper cover 117 and the lower cover 118. The fixing method of the heating element 130 and the fixing assembly 110 can be set as needed and is not limited here.

[0058] Compared with the prior art method in which the liquid guiding member is arranged around the heating member, the atomizer core 100 provided in this embodiment has the heating member 130 and the liquid guiding member 120 stacked and arranged in the fixed component 110, which has a simple assembly process and high production efficiency. Moreover, by adopting the stacked arrangement, the liquid guiding member 120 and the heating member 130 can fit better, and the probability of a gap between the two is low. When the atomized liquid is conducted to the heating member 130 through the liquid guiding member 120, the heating member 130 can fully heat the atomized liquid, so that the atomization effect is good and the working efficiency is high.

[0059] In another embodiment of the present application, please refer to Figure 3 The heating element 130 includes an atomizing portion 131 and a fixing portion 132 which are connected to each other. The resistivity of the atomizing portion 131 is greater than the resistivity of the fixing portion 132. The atomizing portion 131 is fitted with the liquid guiding member 120. The fixing portion 132 is fixedly connected to the fixing assembly 110. The fixing portion 132 is electrically connected to the power supply of the atomizing device body 200 via the first electrical port 115.

[0060] Specifically, the atomization part 131 is made of conductive material, and the atomization part 131 can have a variety of structures, such as a combination of one or more of a mesh-shaped atomization part, a stripe-shaped atomization part, a folded-line atomization part, a curved atomization part, and a spiral atomization part. The shape of the mesh of the mesh-shaped atomization part can be a polygon such as a rectangle or a triangle, or a curved shape such as a circle or an ellipse, which can be set as needed, and is not limited here. The outer contour of the atomization part 131 can be a circle, a rectangle, or other shapes, which can be set as needed, and is not limited here.

[0061] The atomizer core 100 provided in this embodiment has a low resistivity of the fixing portion 132, so the heat generation is low after power is turned on, and the structural stability is good. The fixing portion 132 is fixedly connected to the fixing assembly 110 and electrically connected to the external power supply at the same time, so that the heating element 130 can be firmly fixed in the inner cavity 111, and the electrical connection between the atomizer portion 131 and the external power supply is realized at the same time. The structure is simple and the installation is convenient.

[0062] Optional, see Figure 3 The fixing part 132 includes two sub-fixing parts 1321, which are respectively arranged on opposite sides of the atomizing part 131, and the two sub-fixing parts 1321 are provided with mounting holes 1322, and the fixing assembly 110 is provided with two first electrical ports 115 corresponding to the two sub-fixing parts 1321. When in use, the two screws 1323 are passed through the corresponding mounting holes 1322 to fix each sub-fixing part 1321 on the inner wall of the fixing assembly 110, and the positive and negative poles 140 of the power supply of the atomizing device body 200 are passed through the corresponding first electrical ports 115 to abut against the corresponding sub-fixing parts 1321, so that the heating element 130 can be electrically connected to the power supply and fixedly connected to the fixing assembly 110.

[0063] See also Figure 2 The present application also provides an atomizing device body 200, which is used to be detachably plugged with the atomizing core 100 along the insertion direction. Figures 4 to 6 The atomizing device body 200 includes a shell 210, which has a first accommodating cavity 211 for accommodating atomized liquid, a second accommodating cavity 212 for accommodating a power source, and an airflow cavity 213 for airflow to pass through; the airflow cavity 213 has a second air inlet 2131, a second air outlet 2132, and a plug-in slot 214 located between the second air inlet 2131 and the second air outlet 2132, the second air inlet 2132 and the second air outlet 2132 are both connected to the plug-in slot 214, the plug-in slot 214 is provided with a plug-in interface 2142 for inserting the atomizing core 100 into the plug-in slot 214, and the inner wall of the plug-in slot 214 is provided with a positioning matching portion 2143, a second liquid guide port 2145 for connecting the plug-in slot 214 and the first accommodating cavity 211, and a second power connection port (not shown) for connecting the plug-in slot 214 and the second accommodating cavity 212.

[0064] Specifically, openings 2141 may be provided on opposite sides of the plug slot 214 , and the airflow entering from the second air inlet 2131 of the airflow cavity 213 may flow out from the second air outlet 2132 after passing through the two openings 2141 in sequence.

[0065] The atomization device body 200 provided in this embodiment has a first accommodating cavity 211 that can store atomized liquid and enable the atomized liquid to be introduced into the atomizer core 100 in the plug-in slot 214 through the second liquid guide port 2145 under the action of gravity, and the second accommodating cavity 212 can accommodate a power source and provide power to the atomizer core 200 in the plug-in slot 214 through the second power port, and the airflow cavity 213 can allow external air to enter the plug-in slot 214 through the second air inlet 2131 and take away the airflow in the plug-in slot 214 through the second air outlet 2132. In this way, when the atomizer device main body 200 adopts the above structure and receives the atomizer core 100 in the plug-in slot 214, the atomizer device main body 200 can cooperate with the atomizer core 100 to realize the atomization operation, and the atomizer device main body 200 and the atomizer core 100 are detachably plugged in, which can facilitate the replacement of the parts that need to be replaced separately when one of the atomizer core 100 and the atomizer device main body 200 is damaged or reaches the end of its service life, while retaining other parts that can continue to be used, thereby improving the utilization rate of the entire atomizer device 300 and saving resources.
