The embodiments of the present application will be further described below in conjunction with the accompanying drawings.

As shown in Figures 1 and 2, the atomizer provided in one embodiment of the present application includes an oil cup 100 with an open end and an atomization assembly installed on the open end of the oil cup 100, the atomization assembly includes a mounting base 1, and is arranged on the The heating component 2 on the above-mentioned mounting base 1 and two electrode assemblies for supplying power to the heating component 2 , each electrode assembly has a first electrode part 31 and a second electrode part 32 . There is a vent pipe 110 inside the oil cup 100, and an oil storage chamber 120 is formed between the outer wall of the vent pipe 110 and the inner wall of the oil cup 100 for containing the atomized oil. The oil channel 130 is used to guide the atomized liquid in the oil storage chamber 120 to the oil guide 140 for the heating component 2 to atomize.

The end of the oil cup 100 opposite to the mounting base 1 is used as the suction nozzle end, and the suction nozzle can be integrally formed with the oil cup, or can be installed on the oil cup. Similarly, the vent pipe 110 can be integrally formed with the oil cup, or can be an independent part installed in the oil cup.

The mounting base 1 includes a hollow part, which is mainly used as an air intake channel, so that the external gas can flow to the heating component 2 and mix with the aerosol atomized by the heating component 2, and then be released by the user through the ventilation tube 110 suction. Specifically, when the user inhales, the external air flow passes through the mounting base 1 including the hollow part to reach the bottom of the above-mentioned heating element 2 and continues to flow upward to enter the ventilation tube 110, and the process will bring out the atomized aerosol at the same time. .

In this embodiment, the heating component 2 is arranged on the support body 12 on the top surface of the mounting base 1 . The support surface of the support body 12 is a plane (although the support body 12 is provided with an air duct for air flow, it does not affect its flatness), so the heating element 2 can be placed on the support body 12 flatly and without deformation. The electrode assembly not only supplies power to the heating element 2 , but also fixes the heating element 2 on the mounting seat 1 and the support body 12 .

In this embodiment, the mounting base 1 is provided with two electrode mounting holes 13 at different positions, and each electrode mounting hole 13 is used to accommodate a corresponding electrode assembly; each electrode assembly is in contact with a different position of the heating assembly 2 respectively. In this embodiment, the above-mentioned different positions refer to corresponding positions. For example, taking the most common elliptical cylinder or cylinder as an example, the above-mentioned corresponding positions usually refer to two positions on the long axis of the ellipse. position or two positions on a diameter. Preferably, the distances from the two electrode mounting holes 13 to the mounting base 1 are equal.

In this embodiment, each electrode assembly includes a first electrode part 31 and a second electrode part 32; the first electrode part 31 is screw-shaped, inserted into the mounting hole 13 from the bottom surface 11 of the mounting base 1, and the end Protrude from the mounting seat 1 and enter the set position of the support body 12 ; the end of the first electrode part 31 facing the heating element 2 is provided with a recessed matching hole 14 . The second electrode part 32 is also screw-shaped, passing through the heating element 2 and the support body 12 from top to bottom and fitting into the matching hole 14 for fixing the heating element 2 and the support body 12 on the mounting base 1 . Wherein, the second electrode part 32 is fixed together by fastening with the first electrode part 31 through the hole 14 , so as to fix the heating component 2 and the supporting body 12 together. In this specification and claims, the fastening method means that the two are connected together in a relatively fixed manner, and the connection method may be riveting, interference fit, etc. It can be understood that, because the first electrode part 31 is screw-shaped, by reasonably setting the height of the first electrode part 31 and the mounting base 1, the heat-generating assembly can be installed through the interference fit between the second electrode part 32 and the first electrode part 31. 2 and the support body 12 are clamped and fixed to the mounting base 1.

In this embodiment, the first electrode part 31 and the second electrode part 32 of each electrode assembly are electrically connected, and the two first electrode parts 31 are respectively connected to the positive terminal and the negative terminal of the power supply voltage, so that the power supply voltage A current loop is formed through the heating component 2 to realize heating of the liquid.

In this embodiment, the heating component 2 includes a heating sheet. FIG. 3 shows the specific structure of the heating sheet in this embodiment. suitable) strip of metal material, which includes two fixed ends 21 and a mesh structure 24 connected between the two fixed ends 21 . As shown in FIG. 3 , the set position of the fixed end 21 is provided with a support for passing the electrode assembly (specifically, the second electrode part) and fixing the heating sheet on the mounting base 1 The fixing hole 22 of the body 12; the heating sheet is formed by etching the sheet metal plate to form the fixing end 21 and the mesh structure 24 at one time. Due to the thinner thickness of the heating element, the stamping and forming process is more difficult, and more burrs may appear on the edge of the shape after the stamping and forming process, which will affect the flatness of the heating element itself and the flatness when it is placed on the support body 12 of the mounting base 1 degree. Etching does not have these problems, at least it will not deform the heating sheet itself. In addition, as shown in Figure 3, the edge of the width direction of the above-mentioned network structure (that is, the edge not connected with the above-mentioned fixed end 21) is also provided with a clamping part 23 bent by punching (the clamping position shown in Figure 3 part 23 has not yet been bent), the clamping part 23 is used to clamp the support body 12, so that the relative position between the heating component 2 and the support body 12 is fixed. The bent locking portion 23 can be obtained by simply punching and bending the heating component 2 shown in FIG. 3 .

It is worth mentioning that, in this embodiment, since there is a support body 12, and the support body 12 is made of dense ceramics, its strength and sealing performance are good, so in some cases, the above-mentioned installation may not be used. For the seat 1, for example, the above-mentioned mounting seat 1 may not be used in the case where a smaller volume is required or the cost is more sensitive. In this case, due to the existence of the support body 12, the first electrode part 31 can directly enter the assembled heating element and the support body 12, and then through the second electrode part 32, the above-mentioned first electrode part 31, heat generation The components 2 are connected together to also realize the atomization function.

Specifically, the support body 2 is set on the top surface of the mounting base 1, the heating component 2 is set above the support body 2 and is rigidly supported by the support body 2, and the end of the first electrode part 31 passes through the mounting base 1 and the support body 2 and generates heat toward the mounting base 2. The component extends to a position where it touches the heating component 2 . The heat generating assembly 2 is welded to the end of the first electrode part 31 at its fixing hole 22 so as to be directly connected to said first electrode part 31 in a fastened manner. By adopting the connection method, the connection deformation between the first electrode and the heating component is small, and the consistency of the finished product after assembly is stable.
