Furthermore, the porous fiber body 15 is filled between the outer shell 11 and the air duct 13. The porous fiber body 15 can be a plant fiber extract with a porous structure, or a plastic fiber, chemical fiber, glass fiber, etc. with a porous structure. That is, the porous fiber material in the prior art that can adsorb and fix the atomized medium can be considered to fall within the protection scope of the present invention, and is not limited here. Among them, a through receiving hole 151 is provided in the porous fiber body 15, and the air duct 13 is installed in the receiving hole 151.

In some embodiments, the first seal 17 is disposed at the top of the outer shell 11, that is, at one end close to the suction nozzle 12; the second seal 18 is disposed at the bottom of the outer shell 11, that is, at one end away from the suction nozzle 12. Among them, the first seal 17 is provided with an air hole 171 for air flow to pass through, and the second seal 18 is provided with an air inlet hole 181 for air flow to enter the atomizing device, and the air inlet hole 181, the air guide tube 13, and the air hole 171 are sequentially connected to form an air flow channel, and the air flow channel is connected to the air inlet channel 121 of the suction nozzle 12. In some embodiments, the air duct 13 is inserted into the air hole 171, so that the air duct 13 is fixed in the atomizing device. As a preferred embodiment of the present invention, the air flow channel and the air inhalation channel 121 are both arranged vertically on the bottom surface 1615, and the two are coaxial, thereby forming a straight through channel, so that the air flow can flow smoothly.

[0037] In some embodiments, the atomizing device further includes an atomizing core 16, which is used to heat and atomize the atomizing medium so that the atomizing medium generates an aerosol after being heated. The atomizing core 16 specifically includes a porous atomizing body 161 for adsorbing the atomizing medium and a heating wire 162 for heating the atomizing medium. Among them, the porous atomizing body 161 is a rigid structure, specifically a porous ceramic body.

One end of the pin 163 is connected to the heating wire 162, and the other end extends outside the porous atomizing body 161, so that the heating wire 162 is electrically connected to an external power supply 30 through the pin 163. After the heating wire 162 is powered on, it heats up, and then heats the atomizing medium.

[0038] In the present invention, the porous atomizing body 161 has at least the following two forms, which will be described through two specific embodiments below.

[0039] As the first embodiment of the present invention, referring to Figure 2 and Figure 3 , the porous atomizing body 161 is a cylindrical porous atomizing body with a hollow interior. An atomizing channel 1611 for air flow to pass through is provided through the interior of the porous atomizing body 161. The heating wire 162 is fixedly arranged on the inner side wall of the atomizing channel 1611, so as to form an atomizing area on the atomizing channel 1611. Among them, one end of the atomizing channel 1611 is communicated with the air passing hole 171, and the other end is communicated with the air guide tube 13, so that the atomizing channel 1611 becomes a part of the air flow channel. Further, the porous atomizing body 161 is arranged in the accommodation hole 151 of the porous fiber body 15. In some embodiments, the outer diameter of the porous atomizing body 161 may be slightly larger than the inner diameter of the accommodation hole 151, so that the outer wall of the porous atomizing body 161 can be closely attached to the inner wall of the accommodation hole 151, and the atomizing medium adsorbed in the porous fiber body 15 can be conducted into the porous atomizing body 161. When the user sucks through the suction nozzle 12, the air flow enters the atomizing channel 1611 through the air inlet hole 181 of the second seal 18, so as to bring the aerosol generated after heating and atomization in the atomizing channel 1611 into the air guide tube 13, and enter the suction channel 121 in the suction nozzle 12 through the air passing hole 171, and then enter the user's oral cavity and be inhaled by the user.

[0040] Further, in some embodiments, one end of the porous atomizer 161 facing the air duct 13 is recessed towards the other end to form a limiting step 1612 for positioning and installing the air duct 13. Wherein, the limiting step 1612 is coaxially arranged with the atomization channel 1611, and the outer diameter of the limiting step 1612 is preferably equal to or slightly larger than the outer diameter of the air duct 13. One end of the air duct 13 is inserted into the limiting step 1612, so that the atomization channel 1611 and the air duct 13 are coaxially arranged through the limiting step 1612 to form a straight air flow channel.

[0041] As the second embodiment of the present invention, refer to Figure 4 , the porous atomizer 161 is a flat plate-shaped porous atomizer. Specifically, the flat plate-shaped porous atomizer can extend into the liquid storage chamber 14 along the direction perpendicular to the air duct 13.

Further, the flat plate-shaped porous atomizer includes a bottom surface 1615 and a top surface 1616 arranged opposite to each other. The top surface 1616 faces the direction of the mouthpiece 12. In this embodiment, the heating wire 162 is spirally arranged on the bottom surface 1615, so that the part of the bottom surface 1615 provided with the heating wire 162 is the atomization part 1614. The atomization part 1614 is preferably arranged at the center of the bottom surface 1615; the liquid guiding part 1613 extends into the atomization chamber 22 to contact the porous fiber body 15, adsorbs and guides the atomization medium in the porous fiber body 15 to the atomization part 1614, and after being heated and atomized by the heating wire 162, it becomes an aerosol. Further, the atomization part 1614 is arranged in the air flow channel, so that the aerosol generated by atomization can be inhaled by the user and brought into the user's mouth by the air flow.

[0042] Further, in this embodiment, the flat plate-shaped porous atomizer may specifically be a flat square, that is, the bottom surface 1615 and the top surface 1616 are parallel to each other, both are rectangles or rectangles with chamfers. The height dimension of the flat square porous atomizer is smaller than the length and width of the rectangle or rectangle with chamfers. Specifically, refer to Figure 5 ,. In this embodiment, the liquid guiding parts 1613 are arranged at both ends of the flat square porous atomizer along its length direction. The liquid guiding parts 1613 extend into the atomization chamber 22 to contact the porous fiber body 15. The heating wire 162 is spirally arranged in the middle of the bottom surface 1615 of the flat square porous atomizer and is arranged in the air flow channel, so that the atomization medium is guided to the central atomization part 1614 through the two liquid guiding parts 1613 in contact with the porous fiber body 15, and after being heated by the heating wire 162, an aerosol is generated in the air flow channel. When the user makes a sucking action, the air flow flows in the air flow channel, so as to bring the atomized aerosol into the user's mouth.

[0043] The present invention also provides an electronic atomization device, refer to Figure 6 andFigure 7 , including the atomizing device described above. Additionally, the electronic atomizing device further includes a housing 20 and a power source 30 disposed within the housing 20. The power source 30 is electrically connected to the atomizing core 16. Specifically, the power source 30 is electrically connected to the heating wire 162 through a pin 163, so that the heating wire 162 is powered on and heated, and then the atomizing medium is heated to generate aerosol.

[0044] Furthermore, the interior of the housing 20 is hollow and at least includes a power source compartment 21 for accommodating the power source 30. Among them, an isolation member 40 is further provided at the top of the power source compartment 21 to isolate the power source 30 from the atomizing device through the isolation member 40. In some embodiments, a plurality of through holes for air flow are further provided on the isolation member 40.

[0045] In some embodiments, referring to Figure 6 , the housing 20 and the outer shell 11 of the atomizing device are integrally provided, that is, the housing 20 is fixedly connected to the outer shell 11, making the electronic atomizing device an inseparable whole.

[0046] In other embodiments, referring to Figure 7 , the housing 20 further includes an atomizing compartment 22 for accommodating the atomizing device. The atomizing compartment 22 and the power source compartment 21 are isolated by an isolation member 40. The top of the atomizing compartment 22 is open, and the atomizing device is inserted into the atomizing compartment 22 from the open mouth, so that the atomizing device is detachably connected to the housing 20.

[0047] The atomizing device provided by the present invention can effectively avoid the oil leakage phenomenon of the liquid storage chamber 14 by filling the porous fiber body 15 into the liquid storage chamber 14; at the same time, the porous atomizing body 161 contacts the porous fiber body 15 to ensure that the atomizing medium can be adsorbed and conducted to the porous atomizing body 161 for atomization. The good strength condition of the porous atomizing body 161 makes it not easily deformed, so it can effectively avoid the phenomenon of core burning caused by uneven temperature during the operation of the atomizing core 16. At the same time, it is easy to assemble, saves labor costs, and can improve the assembly efficiency and assembly quality while improving the assembly efficiency.

[0048] The above embodiments only represent several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent.
