The bottom end of the suction channel is connected to the atomization chamber 2410 on the atomization core 2400, so that the aerosol generated by the atomization core 2400 can be discharged from the atomization assembly 2000. When in use, the liquid storage tank 2100 needs to contain a liquid atomization matrix. In order to prevent leakage of the atomization matrix, the inner tube body 2120 and the atomization bracket 2200 are provided with an upper sealing seat 2800. The inner tube body 2120 can be plugged into the opening at the upper end of the upper sealing seat 2800, and the lower end of the upper sealing seat 2800 can be plugged into the atomization bracket 2200.

A buckle structure is provided on the outer peripheral surface of the component base 2300, and the buckle structure can be adapted to the card groove on the inner wall of the liquid storage tank 2100 to fix the component base 2300 on the liquid storage tank 2100. Of course, in a specific embodiment, the fixing form of the component base 2300 and the liquid storage tank 2100 is not limited, and any fixing method can be adopted under the condition of meeting the use requirements, such as interference fit, bonding, etc.

[0058] The component base 2300 fixed on the liquid storage tank 2100 can play a role in positioning the atomizer bracket 2200, and the component base 2300 can be provided with an adapter electrode 2600 to connect to the power supply electrode 1200 on the device body 1000, and the adapter electrode 2600 can be embedded in the component base 2300. In addition, the component base 2300 is provided with an air inlet channel 2310 (see FIG. 21 ) which runs through in the up-down direction. Figure 5 , Figure 7 ), the air inlet channel 2310 is communicated with the middle channel 2220 on the atomizer bracket 2200, and the middle channel 2220 on the atomizer bracket 2200 is communicated with the atomizer cavity 2410 on the atomizer core 2400, so that external air can enter the atomizer core 2400. In a specific embodiment, an air inlet cavity 2320 is provided between the component base 2300 and the atomizer bracket 2200, and the air inlet cavity 2320 is communicated with the air inlet channel 2310 and the middle channel 2220 at the same time.

[0059] In order to prevent condensed and leaked atomized matrix from leaking from the air inlet channel 2310, in a specific embodiment, the atomizer assembly 2000 further includes a liquid absorbent cotton 2700, which is disposed in an air inlet cavity 2320 formed between the atomizer bracket 2200 and the assembly base 2300. The air inlet cavity 2320, as a part of the air inlet path, can communicate with the air inlet channel 2310 and the middle channel 2220 on the atomizer bracket 2200. After the condensed and leaked atomized matrix flows into the cavity, it can be adsorbed and stored by the liquid absorbent cotton 2700, thereby achieving the purpose of preventing leakage.

[0060] The structure of the atomizer core 2400 is introduced below.

[0061] In one embodiment, the atomizer core 2400 is assembled in a mounting tube 2210 disposed at the top of the atomizer bracket 2200. The mounting tube 2210 is located in the radial middle of the atomizer bracket 2200 and protrudes upward from the bracket body of the atomizer bracket 2200.

A connecting hole 2431 is provided on the wall of the isolation tube 2430, and the connecting hole 2431 can allow the atomized matrix adsorbed by the outer cotton 2420 to pass through and be adsorbed by the inner cotton 2440. By controlling the size, number and arrangement position of the connecting holes 2431, the supply speed of the atomized matrix of the inner cotton 2440 can be controlled. The inner cotton 2440 has a central hole, and the central hole forms an atomization cavity 2410. A convex portion 2441 can be provided on one radial side of the inner cotton 2440, and a avoidance port 2432 can be provided on the top of the wall of the isolation tube 2430. The convex portion 2441 can pass through the avoidance port 2432 and contact the outer cotton 2420, and can also realize the supply of the atomized matrix to the inner cotton 2440.

[0063] The heating element 2500 is the core element of the atomizer core 2400. The heating element 2500 is disposed in the inner cotton packing 2440 and is used to heat the atomizer matrix to generate aerosol. Figure 6 The heating element 2500 may be an arc-shaped mesh sheet, which may be formed by bending a flat sheet or directly forming a mesh with an arc-shaped structure.

[0065] The first common conductor part 2511 and the second common conductor part 2512 are used to connect the corresponding ends of each heating part 2520 at the same time. The first common conductor part 2511 and the second common conductor part 2512 are arranged side by side. The side by side arrangement means that they are arranged in parallel on the same straight line, and the arrangement direction is perpendicular to the straight line. The ends of the objects arranged side by side in the direction perpendicular to the straight line are basically flush. Please refer to Figure 5 , Figure 6 The first common conductor part 2511 and the second common conductor part 2512 are arranged at intervals in the up-down direction, that is, distributed in the up-down direction, with the spacing direction of the two being the conductor distribution direction, and the conductor distribution direction is parallel to the axial direction of the atomization chamber 2410, that is, the up-down direction in the figure. In one embodiment, the first common conductor part 2511 and the second common conductor part 2512 can be a flat sheet structure. Of course, in other embodiments, the first common conductor part 2511 and the second common conductor part 2512 can also be other shapes, such as a block structure, a columnar structure, etc.

[0066] The heating portion 2520 extends in a corrugated shape between the first common conductor portion 2511 and the second common conductor portion 2512, and the crests and troughs of the heating portion 2520 are connected to the side extension portion 2550, and the side extension portion 2550 is perpendicular to the axial direction of the atomizing chamber 2410; the side extension portion 2550 connected to the crest of at least one heating portion 2520 is connected to the side extension portion 2550 connected to the trough of the adjacent heating portion 2520, that is, the crests or troughs on the adjacent two heating portions 2520 located at the same position along the axial direction of the atomizing chamber 2410 are connected to each other through the side extension portion 2550. The shape and size of each heating portion 2520 can be the same, and the side extension portion 2550 can have no current or very little current passing through it, and the heat can be mainly generated by the heating portion 2520. The side extension portion 2550 is conducive to increasing the heating area and maintaining the structural stability of the heating element.

[0067] It should be noted that the waveform shape of the heating portion 2520 is not limited and can be determined according to the heating requirements and manufacturing process. For example, the waveform of the heating portion 2520 can be a triangular wave as shown in the figure, or a sine wave, a rectangular wave, etc. In addition, in some other embodiments, the side extension portion 2550 connected to the peak or trough of the heating portion 2520 can be omitted, and the side extension portions 2550 on adjacent heating portions 2520 can be separated from each other. Furthermore, in some other embodiments, the number of the heating portions 2520 can be more than three.

[0068] Those skilled in the art can understand from the accompanying drawings that in the illustrated embodiment, the heating portion 2520 is provided at two locations, each heating portion 2520 surrounds the axis of the atomizing chamber 2410, each heating portion 2520 is connected between the first common conductor portion 2511 and the second common conductor portion 2512, the extension direction of each heating portion 2520 is parallel to the axial direction of the atomizing chamber 2410, and the above conductor distribution direction is parallel to the axial direction of the atomizing chamber 2410. It should be noted that the surrounding angle of each heating portion 2520 around the axis of the atomizing chamber 2410 can be 360 ​​degrees, or less than 360 degrees.

[0069] The bent portion 2530 can facilitate the connection of the pin 2540. In one embodiment, the first common conductor portion 2511 is connected to a first bent portion, and the end of the first bent portion is flush with the second common conductor portion 2512; the second common conductor portion 2512 is connected to a second bent portion, and the end of the second bent portion is flush with the first common conductor portion 2511. The provision of the bent portion 2530 is conducive to improving the symmetry of the heating element. When the heating element is bent from a flat sheet into a cylindrical shape to be arranged on the hole wall of the central hole, the structure of both sides of the heating element can be made more symmetrical; at the same time, the pin 2540 can be fixedly connected to one side of the thickness direction of the bent portion 2530, and the bent portion 2530 is convenient for the lead-out of the pin 2540. The end of the pin 2540 away from the common conductor portion can be connected to the adapter electrode 2600 arranged on the component base 2300.

[0070] In a specific embodiment, please refer to Figure 4 , Figure 5, a portion of the adapter electrode 2600 is exposed in the air inlet cavity 2320, the pin 2540 includes a first portion passing through the middle channel 2220 and a second portion arranged in an L shape with the first portion, the second portion is located in the air inlet cavity 2320 and connected to the adapter electrode 2600. In addition, the liquid absorbent cotton 2700 is provided with an avoidance hole 2710, a portion of the adapter electrode 2600 is located in the avoidance hole 2710, the liquid absorbent cotton 2700 is provided with a connecting groove 2720, and the second portion of the pin 2540 passes through the connecting groove 2720. The provision of the liquid absorbent cotton 2700 is conducive to preventing the atomized matrix from leaking from the air inlet channel 2310, and the connecting groove 2720 on the liquid absorbent cotton 2700 can realize the connection between the pin 2540 and the adapter electrode 2600.

[0071] Those skilled in the art will appreciate that, in some other embodiments, the bent portion 2530 may be omitted, or the bent portion 2530 may be provided on only one of the common conductor portions. For the common conductor portion not connected with the bent portion 2530, the pin 2540 may be directly connected to the end of the common conductor portion in the length direction. In addition, the pin 2540 may also be connected to the end of the bent portion 2530.

[0072] When the atomizer assembly 2000 is working, the device body 1000 of the electronic atomizer device supplies power to the atomizer assembly 2000, and the heating part 2520 of the heating element generates heat under the action of the current. Since the heating part 2520 is parallel to the axial direction of the atomizer chamber 2410, the main heat radiation and heat conduction can be limited between the first common conductor part 2511 and the second common conductor part 2512, and radiate along the circumference of the atomizer chamber 2410. Compared with the circumferential arrangement of the heating part 2520 along the atomizer chamber 2410, the upper side of the uppermost heating part 2520 and the lower side of the lowermost heating part 2520 will generate more energy dissipation. The utility model can improve energy utilization and better avoid energy waste. In addition, the shrinkage of the first common conductor part 2511 and the second common conductor part 2512 is limited, so it can limit the shrinkage deformation of the heating element along the radial direction of the atomizer chamber 2410 when it works for a long time, thereby avoiding the influence of radial shrinkage deformation on the suction resistance, taste and service life.

[0076] The structure of the heating element may be the same as the structure of the heating element 2500 in any embodiment of the electronic atomization device described above, and will not be described in detail here.

In a specific embodiment, the heating element 2500 can also be applied to other types of electronic atomizer devices, such as an electronic atomizer device in which the atomizer assembly 2000 is integrated on the device body 1000.

[0078] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
