[0041] Among them, see Figures 1 to 4 The fixing seat 110 is used for installation with the oil storage assembly; the mounting seat 120 is connected to the fixing seat 110, and a receiving cavity 121 is formed in the mounting seat 120. A first oil inlet groove 122 is provided on the side wall of the mounting seat 120, and the first oil inlet groove 122 extends in the axial direction of the mounting seat 120, and the first oil inlet groove 122 is communicated with the receiving cavity 121; the heating wire 130 includes a heating body 131 and a pin 132, the heating body 131 is received in the receiving cavity 121, and the pin 132 passes through the fixing seat 110; the first oil storage cotton 140 is coated on the outside of the heating body 131, and at least partially received in the receiving cavity 121; the second oil storage cotton 150 is coated on the outside of the mounting seat 120.

[0042] In the above-mentioned atomizer core assembly 100, the mounting seat 120 is mounted on the fixing seat 110, and the fixing seat 110 is used to be mounted with the oil storage assembly, so that the oil storage assembly can supply oil to the oil storage cotton on the mounting seat 120, by arranging two layers of oil storage cotton on the mounting seat 120: a first oil storage cotton 140 and a second oil storage cotton 150, wherein the first oil storage cotton 140 is at least partially accommodated in the accommodating cavity 121 of the mounting seat 120, and the second oil storage cotton 150 is covered outside the mounting seat 120, so that the first oil storage cotton 140 and the second oil storage cotton 150 can both absorb the smoke oil provided by the oil storage assembly, In addition, the tobacco oil in the first oil storage cotton 140 and the second oil storage cotton 150 can be connected to each other through the first oil inlet groove 122 and the oil inlet hole 123. When the heating wire 130 heats the first oil storage cotton 140, the second oil storage cotton 150 can also supply tobacco oil to the first oil storage cotton 140, so that the tobacco oil in the entire atomization core assembly 100 can be in a full state. In the heated state, the oil storage assembly provides a stable oil inlet rate and oil inlet amount, avoiding the phenomenon of "core sticking" due to insufficient oil supply when only a single layer of oil storage cotton is arranged in the receiving cavity 121 of the mounting seat 120 and heated.

[0043] See also Figures 1 to 4 In one embodiment of the present invention, the fixing seat 110 includes a base 111, a seal 112 and a sleeve 113. The base 111 and the seal 112 are located at opposite ends of the mounting seat 120. The base 111 is partially accommodated in the accommodating cavity 121. The pin 132 of the heating wire 130 passes through the base 111. The mounting seat 120 is partially accommodated in the sleeve 113. The sleeve 113 is covered on the outside of the second oil storage cotton 150. One end of the sleeve 113 is connected to the seal 112, and the other end is connected to the mounting seat 120, so that it is installed with the power supply mechanism through the base 111, and the seal 112 and the sleeve 113 are installed with the oil storage assembly.

[0044] Specifically, a through hole 1131 is provided on the sleeve 113 , and the through hole 1131 can be communicated with the oil storage chamber in the oil storage assembly, so as to provide tobacco oil to the first oil storage cotton 140 and the second oil storage cotton 150 .

[0045] The sealing member 112 is provided with an annular installation cavity 1121 , and the sleeve 113 is inserted into the installation cavity 1121 , thereby realizing the installation of the sleeve 113 and the sealing member 112 .

[0046] Among them, the base 111 is partially accommodated in the accommodating cavity 121. When installed with the mounting base 120, the mounting base 120 is provided with a card slot 124. Correspondingly, a protrusion 1111 is provided on the base 111, and the protrusion 1111 is clamped in the card slot 124, so as to facilitate the positioning of the base 111 installed on the mounting base 120.

[0047] Among them, see Figure 5 A first support platform 125 is disposed around the outer periphery of the mounting seat 120 , and a portion of the mounting seat 120 is covered by the sleeve 113 , and the other end of the sleeve 113 is supported on the first support platform 125 .

[0048] The mounting base 120 in this embodiment is provided with an oil inlet hole 123. Figure 5 In one embodiment of the present invention, a second oil inlet groove 126 is further provided on the mounting seat 120. The second oil inlet groove 126 is arranged in the axial direction of the mounting seat 120, and the depth of the second oil inlet groove 126 is less than the depth of the mounting cavity 1121. In addition, by providing the second oil inlet groove 126, not only can the first oil storage cotton 140 be conveniently installed, but also the oil accumulated at the bottom of the mounting seat 120 can be prevented from flowing out from the top of the mounting seat 120. At the same time, the second oil storage cotton 150 and the first oil storage cotton 140 have more contact area, which is convenient for providing smoke oil to the first oil storage cotton 140.

[0049] Among them, in order to facilitate the mold to groove the first oil inlet groove 122 and the second oil inlet groove 126 on the mounting base 120, the first oil inlet groove 122 and the second oil inlet groove 126 in this example are arranged at an angle of 180 degrees relative to each other. In other embodiments, the two can also be arranged at other angles according to the setting relationship with the oil inlet hole 123.

[0050] The difference between the depth of the second oil inlet groove 126 and the depth of the first oil inlet groove is between 2-4 mm, thereby preventing the oil storage cotton from leaking oil.

[0051] See also Figure 3In one embodiment of the present invention, one end of the first oil storage cotton 140 is received in the receiving cavity 121, and the other end is passed through the first oil inlet groove 122 and connected to the second oil storage cotton 150. After the installation of the first oil storage cotton 140 in the receiving cavity 121 is completed, the first oil storage cotton 140 passes through the first oil inlet groove 122, and then directly surrounds the second oil storage cotton 150 on the outside of the mounting seat 120.

[0052] Specifically, the first oil storage cotton 140 and the second oil storage cotton 150 in this embodiment are integrally formed, so as to facilitate the preparation and production of the entire oil storage cotton. In other embodiments, the first oil storage cotton 140 and the second oil storage cotton 150 can also be two separate entities, and the separate first oil storage cotton 140 is first installed in the mounting seat 120, and then the second oil storage cotton 150 is arranged around the outer periphery of the mounting seat 120.

[0053] The outer periphery of the mounting seat 120 may further be surrounded by a second support platform for supporting the second oil storage cotton 150 .

[0054] Also, see Figure 4 and Figure 5 In one embodiment of the present invention, the bottom of the first oil storage cotton 140 is lower than the bottom wall 1221 of the first oil inlet groove 222, which is equivalent to that the mounting seat 120 is also provided with a protrusion at the position of the first oil inlet groove 222. Through the setting of the protrusion, the smoke oil gathered at the bottom of the mounting seat 120 is blocked to prevent excessive direct outward flow.

[0055] It can be understood that in order to achieve sealing, the atomizer core assembly 100 further includes a sealing sleeve 160 , and the sealing sleeve 160 is sleeved outside the second oil storage cotton 150 .

[0056] See also Figure 3 The heating wire 130 in this embodiment includes a heating body 131 and a pin 132. The first oil storage cotton 140 is wrapped outside the heating body 131. The pin 132 passes through the base 111. In order to achieve the sealing between the pin 132 and the base 111, after the pin 132 passes through the base 111, glue is applied at the location of the penetration hole to improve the sealing of the entire atomization core assembly 100 and prevent oil leakage.

[0057] Specifically, during installation, the heating body 131 is sleeved on the cylindrical auxiliary rod, the first oil storage cotton 140 is wrapped around the outside of the heating body 131, and one end of the first oil storage cotton 140 is passed through the first oil inlet groove 122. At this time, the auxiliary rod is pulled out, and the second oil storage cotton 150 is wrapped around the outside of the mounting seat 120 to complete the installation of the two layers of oil storage cotton.

[0058] The above-mentioned atomizer core assembly 100 is provided with a second oil inlet groove 126 on the mounting seat 120, which not only facilitates the installation of the first oil storage cotton 140, but also prevents the oil accumulated at the bottom of the mounting seat 120 from flowing out from the top of the mounting seat, and at the same time makes the second oil storage cotton 150 and the first oil storage cotton 140 have more contact area, which is convenient for providing oil to the first oil storage cotton 140 wrapped outside the heating wire 130, and more effectively makes the oil in the entire atomizer core assembly 100 full of oil, ensuring a stable oil inlet rate and oil inlet amount, and can avoid the dry burning phenomenon caused by insufficient oil in the atomizer core.

[0059] See also Figure 6 In other embodiments, the present invention further provides an atomizer 200, including an oil storage component and the above-mentioned atomizer core component 100, the atomizer core component 100 is connected to the oil storage component, and the oil storage component is used to provide smoke oil to the atomizer core component.
