[0023] In related technologies, the heating element of the atomizer coil assembly is typically connected to electrodes via pins to achieve conductivity. However, when the pins need to be bent due to installation or structural requirements, they can easily cause the inner core of the atomizer coil assembly (including the heating element and atomizing support) to shift position under stress. This positional shift can not only cause the inner core to tilt or move upward, reducing the contact area between components in the liquid transmission path or potentially breaking the transmission path, thus affecting the stability of the liquid supply, but also lead to insufficient liquid supply to the heating element during operation and potentially causing burning. Furthermore, the change in the inner core's position can also compromise the sealing effect, resulting in oil leakage.

[0024] Therefore, this application provides an atomizing core assembly 104, an atomizer 101, and an electronic atomization device to solve the problems in the related technology.

[0025] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0026] Combination Figure 1 and Figure 2As shown in the figure, an electronic atomizing device provided in this application embodiment includes a power supply device 102 and an atomizer 101; the power supply device 102 supplies power to the atomizer 101. For example, the atomizer 101 and the power supply device 102 are detachably electrically connected, and the power supply device 102 has a battery, thereby enabling the atomizer 101 to atomize the aerosol matrix.

[0027] Combination Figures 3 to 6 As shown, in some embodiments, the atomizer 101 includes a liquid reservoir 103 and an atomizing core assembly 104. The liquid reservoir 103 and the atomizing core assembly 104 cooperate to form a liquid storage chamber 105, which is used to store the aerosol matrix. Exemplarily, the atomizer 101 may also include absorbent cotton (not shown), which is located in the liquid storage chamber 105 and is used to store the aerosol matrix.

[0028] Combination Figures 7 to 9 As shown in this embodiment, the atomizing core assembly 104 includes an inner core and an outer cover 107. The inner core includes a heating element 108, a first liquid guiding element 109, an atomizing bracket 110, a first gasket 111, and a first sealing element 112. The first liquid guiding element 109 is sleeved outside the heating element 108, and the atomizing bracket 110 is sleeved outside the first liquid guiding element 109. The top end of the atomizing bracket 110 is inserted into the first gasket 111. The first gasket 111 has a first limiting surface 113, which limits the top end of the atomizing bracket 110. The bottom end of the atomizing bracket 110 is inserted into the first sealing element 112. The inner core is located in the outer cover 107, wherein the first gasket 111 and the first sealing element 112 respectively cooperate with the inner wall of the outer cover 107.

[0029] This application utilizes the first limiting surface of the first washer 111 to limit the movement of the inner core in the axial direction by contacting the top of the atomizing bracket 110, thus preventing the inner core from shifting upwards or tilting due to bending stress on the pins of the heating element 108. The cooperation between the first washer 111 and the first seal 112 with the inner wall of the outer cover 107 forms a multi-point fixing structure, enhancing the stability of the inner core and preventing its radial or axial displacement, which also helps to reduce or prevent liquid leakage. In this way, the stability of the inner core position ensures that the relative positions of the heating element 108, the first liquid guiding element 109, and the atomizing bracket 110 are fixed, thereby ensuring that the liquid (e.g., aerosol matrix) can be uniformly and continuously transferred to the heating element 108. The stable liquid supply can reduce local overheating or burning caused by insufficient liquid supply, thereby improving the working reliability and atomization effect of the atomizing core assembly 104.

[0030] For ease of description, the height direction of the atomizer 101 is defined as the ZZ direction, and the height direction of the outer cover 107 and the height direction of the atomizing bracket 110 are parallel to the height direction of the atomizer 101.

[0031] See Figure 10 As shown, in some embodiments, the first limiting surface of the first gasket 111 can abut against the end face of the top of the atomizing bracket. The first liquid guiding element 109 is made of polyester fiber, organic cotton, or silicone foam. It is understood that the first liquid guiding element 109 can also be made of other materials capable of absorbing liquid. The atomizing bracket 110 can be made of copper, stainless steel, silver, or aluminum alloy. The first gasket 111 can be made of plastic or metal. Metal can be copper, stainless steel, silver, or aluminum alloy; plastic can be PPS (polyphenylene sulfide), PI (polyimide), or PTFE (polytetrafluoroethylene). The first sealing element 112 can be made of silicone or rubber.

[0032] Combination Figures 11 to 14 As shown, in some embodiments, the outer cover 107 is a tubular structure open at both ends, with a first cavity 114 and an inner core located within it. The outer cover 107 has a plurality of first liquid guiding holes 115 circumferentially. The battery of the power supply device 102 is electrically connected to the heating element 108. The atomizing bracket 110 is a tubular structure open at both ends, with a plurality of second liquid guiding holes 116 circumferentially. The first gasket 111 and the first seal 112 respectively radially limit the atomizing bracket 110. The first limiting surface 113 can also axially limit the atomizing bracket 110 (i.e., limit the atomizing bracket 110 in the height direction) to reduce or avoid axial movement of the inner core relative to the outer cover 107 or tilting relative to the height direction of the atomizing bracket 110. For example, the first limiting surface 113 can be a plane, perpendicular to the height direction of the atomizing bracket 110. The first liquid guiding element 109 is sleeved on the outside of the heating element 108, thus partially enclosing the heating element 108. This allows the first liquid guiding element 109 to transfer the aerosol matrix to the heating element 108. When the heating element 108 is energized and heated, the aerosol matrix can be atomized into aerosol. The first sealing element 112 is annular and can contact the inner wall of the outer cover 107 to achieve an interference fit. The first sealing element 112 can also contact the outer surface of the atomizing bracket 110 to achieve an interference fit, thereby reducing the possibility of leakage. The first gasket 111 is annular and can have a preset gap between it and the inner wall of the outer cover 107.

[0033] It should be noted that in some other possible embodiments, the first washer 111 may also be in contact with the inner wall of the outer cover 107 to achieve an interference fit between the first washer 111 and the outer cover 107.

[0034] Combination Figure 9 and Figure 15 As shown, in some embodiments, the inner core further includes a second liquid guiding component 117. The second liquid guiding component 117 is sleeved on the outside of the atomizing bracket 110. In the height direction of the atomizing bracket 110, the second liquid guiding component 117 is located between the first gasket 111 and the first seal 112. The second liquid guiding component 117 abuts against the first gasket 111 and the first seal 112 respectively. The second liquid guiding component 117 is interference-fitted with the outer cover 107. The second liquid guiding component 117 can directly draw the aerosol matrix stored in the liquid storage chamber 105, and then the second liquid guiding component 117 transfers the aerosol matrix to the first liquid guiding component 109, thereby ensuring the stability of the liquid transfer path and avoiding interruption or uneven liquid supply caused by the inner core offset, thereby reducing the risk of burning. The interference fit between the second liquid guide 117 and the outer cover 107 reduces the possibility of the inner core tilting. The second liquid guide 117 is located between the first gasket 111 and the first seal 112, which also provides axial restraint for the second liquid guide 117. For example, the second liquid guide 117 is sleeved on the outside of the atomizing bracket 110, thus partially enclosing the atomizing bracket 110. The material of the second liquid guide 117 is polyester fiber, organic cotton, or silicone foam; it is understood that the material of the second liquid guide 117 can also be other liquid-absorbing materials. The first gasket 111 and the first seal 112 are spaced apart along the height direction of the atomizing bracket 110. The aerosol matrix in the liquid storage chamber 105 can enter through the first liquid guide hole 115 and be transferred to the second liquid guide 117, then through the second liquid guide hole 116 to the first liquid guide 109, and finally through the first liquid guide 109 to the heating element 108.

[0035] Combination Figure 9 and Figure 15As shown, in some embodiments, the atomizing core assembly 104 further includes a first fixing seat 118, which has a first receiving groove 119. A portion of the structure of the first sealing member 112 is inserted into the first receiving groove 119, and the end face of the bottom end of the atomizing bracket 110 abuts against the bottom of the first receiving groove 119. In this way, with the cooperation of the first fixing seat 118 and the first limiting surface 113, the atomizing bracket 110 is limited in its own height direction to prevent it from moving up and down; and the first fixing seat 118 can also axially limit the first sealing member 112. For example, the first fixing seat 118 has an axial extension 120 and a first stop surface 121. The outer cover 107 is sleeved on the axial extension 120, and the end face of the bottom end of the outer cover 107 abuts against the first stop surface 121 to achieve axial positioning of the outer cover 107. The first fixing seat 118 also abuts against the end face of the axial extension 120, which can limit the first seal 112. The bottom of the first receiving groove 119 has an opening structure 122, which facilitates the entry of external gas into the internal channel 128 of the atomizing core assembly 104 through the opening structure 122.

[0036] See Figure 7 As shown, in some embodiments, the outer cover 107 has a second limiting surface 123 inside; the first washer 111 abuts against the second limiting surface 123 to limit the first washer 111 in the height direction of the outer cover 107, thus achieving axial limiting of the first washer 111, thereby ensuring axial limiting of the atomizing bracket 110 and ensuring the stability of the inner core's position in the outer cover 107. For example, the second limiting surface 123 can be a plane, and the second limiting surface 123 can be perpendicular to the height direction of the outer cover 107.

[0037] See Figure 17 As shown, in some embodiments, the heating element 108 includes a main pin 124, at least one secondary pin 125, and at least one heating mesh 126. One side of the heating mesh 126 is fixedly connected to the main pin 124, and the opposite side of the heating mesh 126 is fixedly connected to the secondary pin 125. The heating mesh 126, as the core heating element, is fixed via the main pin 124 and its respective secondary pin 125, forming two independent heating areas that can be used for regional heating to meet different application scenarios. For example, the heating mesh 126 can be made of nickel-chromium alloy, stainless steel, or titanium alloy. The heating mesh 126 is bent into an arc shape.

[0038] See Figure 17As shown, in some embodiments, the heating element 108 includes two secondary pins 125 and two heating meshes 126. One heating mesh 126 is fixedly connected to one of the secondary pins 125 on its opposite side, and the other heating mesh 126 is fixedly connected to the other secondary pin 125 on its opposite side. This allows for zoned heating to meet different usage scenarios. For example, the two heating meshes 126 are spaced apart along the height of the atomizer 101. For example, there is one main pin 124, which is fixedly connected to one side of each of the two secondary pins 125. The main pin 124 can be made of nickel-chromium alloy, stainless steel, titanium alloy, or copper; the secondary pins 125 can also be made of nickel-chromium alloy, stainless steel, titanium alloy, or copper.

[0039] See Figure 9 As shown, in some embodiments, the inner core further includes a first base 127, which is inserted into the atomizing bracket 110, with an interference fit between the first base 127 and the atomizing bracket 110; the secondary pin 125 and the main pin 124 respectively protrude from the gap between the first base 127 and the atomizing bracket 110. This first base 127 ensures the structural stability of the atomizing bracket 110, reducing the possibility of deformation during assembly and use; and it also secures the secondary pin 125 and the main pin 124, ensuring the stable position of the heating mesh 126 within the inner core. The first base 127 may have a through-hole structure 129. The internal channel 128 of the atomizing core assembly 104 may include the through-hole structure 129 of the first base 127, part of the internal space of the atomizing bracket 110, the internal space formed after the heating mesh 126 is bent, the internal space enclosed by the first gasket 111, and part of the structure of the first cavity 114 of the outer cover 107.

[0040] Combination Figure 9 and Figure 18 As shown, in some embodiments, the atomizing core assembly 104 further includes a second base 130, a main electrode 131, and at least one auxiliary electrode 132. The main electrode 131 and the auxiliary electrode 132 are respectively fixed to the second base 130. The main electrode 131 is electrically connected to the main pin 124, and the auxiliary electrode 132 is electrically connected to the auxiliary pin 125. The second base 130 provides structural support for the main electrode 131 and the auxiliary electrode 132, ensuring that the electrodes will not shift position under pin bending or external force. This design indirectly stabilizes the heating mesh 126 connected to the main pin 124 and the auxiliary pin 125 by fixing the electrodes to the second base 130, reducing the risk of tilting or upward movement of the core. For example, the second base 130 and the first fixing seat 118 can be fixedly connected by snap-fit ​​connection, threaded connection, or adhesive bonding; the second base 130 has a clearance notch 133 so that external gas can enter the opening structure 122 on the first fixing seat 118 through the clearance notch 133.

[0041] Combination Figure 6 and Figure 19 As shown, in some embodiments, the liquid storage tank 103 includes a suction nozzle 134, a sealing seat 135, and a second sealing element 136. The suction nozzle 134 has a first channel 137 and a first inner cavity 138. One end of the outer cover 107 is inserted into the first channel 137, and the other end of the outer cover 107 is inserted into the sealing seat 135. The sealing seat 135 is installed in the first inner cavity 138. The second sealing element 136 covers part of the structure of the sealing seat 135, and the second sealing element 136 is in a sealing fit with the cavity wall of the first inner cavity 138. In this way, suction can be achieved through the suction nozzle 134, while the sealing seat 135 and the second sealing element 136 can ensure that the stored aerosol matrix will not leak accidentally. For example, the material of the second sealing element 136 can be silicone. The second sealing element 136 contacts the cavity wall of the first inner cavity 138 of the suction nozzle 134, and the sealing seat 135 ensures the sealing of the connection between the second sealing element 136 and the cavity wall of the first inner cavity 138. The first channel 137 has two open ends. One end of the first channel 137 and one end of the outer cover 107 can be sealed together by a sealing ring. The opening at the other end of the first channel is located at the top of the suction nozzle 134 so that suction can be achieved through the suction nozzle 134. After the other end of the outer cover 107 is inserted into the through hole on the sealing seat 135, the axial extension 120 of the first fixing seat 118 is inserted into the other end of the outer cover 107.

[0042] Combination Figure 6 and Figure 20As shown, in some embodiments, the atomizer 101 further includes a bottom cover 139, which is sealed to the wall of the first inner cavity 138. The liquid storage chamber 103 has a second channel 140, and the mouthpiece 134 has a first air inlet 141 on its side. The first air inlet 141 communicates with the second channel 140, which communicates with the internal channel 128 of the atomizing core assembly 104. The internal channel 128 communicates with the first channel 137. Thus, the bottom cover 139 further ensures the sealing of the liquid storage chamber 105 and allows the sealing seat 135 to be stably located in the first inner cavity 138 of the mouthpiece 134. For example, the atomizer 101 may also include a magnet 142, which is fixed to the bottom cover 139, facilitating a detachable and fixed connection between the atomizer 101 and the power supply device 102 via magnetic attraction. The second base 130 is inserted into the through hole on the bottom cover 139. The second base 130 and the through hole of the bottom cover 139 can be sealed and connected by a sealing ring or adhesive. The bottom cover 139 and the second base 130 cooperate to form an air intake chamber 143. The sealing seat 135 also has a second air intake hole 144. The second channel 140 and the air intake chamber 143 are connected through the second air intake hole 144. The bottom cover 139 and the sealing seat 135 can be fixedly connected by snap-fit ​​or adhesive; the bottom cover 139 and the nozzle 134 can be fixedly connected by adhesive to achieve a sealed fit between the bottom cover 139 and the cavity wall of the first inner cavity 138. The path of external gas entering from the first air inlet 141 and flowing out from the opening at the other end of the first channel 137 is as follows: first air inlet 141, second channel 140, second air inlet 144, air inlet cavity 143, clearance notch 133, opening structure 122, internal channel 128 of the atomizing core assembly 104 and first channel 137.

[0043] See Figure 20 As shown, in some embodiments, the atomizer 101 further includes an air regulating component disposed in the second channel 140, which is used to adjust the communication area between the first air inlet 141 and the second channel 140, so that different air intake volumes can be achieved to meet different needs.

[0044] See Figure 20As shown, in some embodiments, the airflow regulating assembly includes an airflow regulating seat 145 and an actuating member 146. The airflow regulating seat 145 is slidably disposed in the second channel 140. A portion of the actuating member 146 extends into the first air inlet 141. The actuating member 146 is fixedly connected to the airflow regulating seat 145. The airflow regulating seat 145 has multiple airflow regulating holes 147. The first air inlet 141 and the second channel 140 are connected through the airflow regulating holes 147. By operating the actuating member 146, the airflow volume can be adjusted. A portion of the actuating member 146 extends into the first air inlet 141 to define the position of the airflow regulating assembly on the mouthpiece 134. For example, the airflow regulating seat 145 cooperates with the second channel 140 to achieve the sliding placement of the airflow regulating seat 145 in the second channel 140. The multiple airflow regulating holes 147 are spaced apart along the height direction of the atomizer 101. The orifice area of ​​each air regulating hole 147 can be the same. When the air regulating seat 145 moves from one end of the outer cover 107 to the other end, the number of exposed air regulating holes 147 gradually increases, thereby realizing the adjustment of the air intake.

[0045] It should be noted that in some other possible embodiments, the orifice area of ​​the plurality of air regulating holes 147 may gradually increase or gradually decrease along the direction from one end of the outer cover 107 to the other end.

[0046] In some embodiments, the atomizer 101 further includes a first air tube 148, the top of the mouthpiece 134 has a top through hole 149, the bottom cover 139 has a bottom through hole 150, the top end of the first air tube 148 is connected to the top through hole 149, and the bottom end of the first air tube 148 is connected to the bottom through hole 150; part of the structure of the first air tube 148 is located in the second channel 140, so that during inhalation, the airflow sensor in the power supply device 102 can be activated to realize automatic control of powering on or off the heating element 108.

[0047] In some embodiments, the nozzle 134 is also provided with a liquid injection hole, and the atomizer 101 also includes a liquid injection plug 151. The liquid injection plug 151 is sealed to the liquid injection hole, so that when the liquid storage chamber 105 lacks aerosol matrix, the liquid injection plug 151 is opened to expose the liquid injection hole, and the aerosol matrix is ​​injected into the liquid storage chamber 105 through the liquid injection hole.
