The power supply assembly is used to supply power to the atomizer 10, enabling the atomizer 10 to atomize the liquid atomizing matrix when powered on.

[0038] As shown in the figure, in some embodiments, the atomizer 10 may have a generally semi-circular structure, which includes an atomizing housing 1 and an atomizing body 2 embedded in the atomizing housing 1. The atomizing housing 1 is used to contain the liquid atomizing matrix and the atomizing body 2, and the atomizing body 2 is used to atomize the liquid atomizing matrix after being powered on.

[0039] In some embodiments, the atomizing housing 1 may include a liquid storage chamber 13 and an opening 14 connecting the liquid storage chamber 13 to the environment. The liquid storage chamber 13 is used to store a liquid atomizing matrix, and the opening 14 is used for embedding the atomizing body 2. In some embodiments, the atomizing body 2 may be embedded in the opening 14 and the opening 14 may be sealed to atomize the liquid atomizing matrix in the liquid storage chamber 13.

[0040] In some embodiments, the atomizing housing 1 may include a first panel 11, a second panel 12, and a sidewall 16.

In some embodiments, the sidewall may be arc-shaped, with its two opposite sides connecting to the edges of the first and second panels, respectively, together defining a semi-circular liquid storage cavity 13. The straight edges of the first and second panels 11 and the two ends of the sidewall together define the aforementioned opening 14. An atomizing outlet 111 is also formed on the first panel 11 near the opening. In some embodiments, the first panel 11, the second panel 12, and the sidewall 16 may be integrally formed. In some embodiments, the atomizing housing 1 may be made of a material such as transparent plastic.

[0041] like Figure 2 and Figure 5 As shown, in some embodiments, the atomizing body 2 may include a base 3 and an ultrasonic atomizing plate 21, electrodes 6, and magnetic attractors 7 mounted on the base 3. The electrodes may be provided in pairs, each pair electrically connected to the ultrasonic atomizing plate 21 to connect the ultrasonic atomizing plate 21 to the positive and negative terminals of the power supply component. The magnetic attractors 7 may also be provided in pairs, used to magnetically attract the atomizer 10 to the power supply component. In some embodiments, the number of magnetic attractors 7 is not limited to a pair; it may be at least one, and the number of magnetic attractors 7 can be adjusted according to actual conditions. In some embodiments, the magnetic attractor 7 may be a magnet.

[0042] For example Figure 4 As shown, in some embodiments, the base 3 may include a base body 31 and a bracket 32. In some embodiments, the base body 31 may be columnar with a racetrack-shaped cross-section for sealing the opening 14. In some embodiments, the bracket 32 ​​may be disc-shaped, with one side connected to the top surface of the base body 31 near the first panel 11, and extending along a direction parallel to the axis of the base body 31 for mounting the ultrasonic atomizing sheet. In some embodiments, the bracket 32 ​​also includes a support portion 33 extending towards the second panel 12 and abutting against it, serving a supporting and limiting function. In some embodiments, the base body 31 and the bracket 32 ​​may be integrally formed and may be made of materials such as silicone.

[0043] In some embodiments, the base body 31 may include a bottom surface 311, a top surface 312 opposite to the bottom surface 311, a first side surface 313 opposite to the first panel 11, and a second side surface 314 opposite to the first side surface. In some embodiments, the base body 31 may also include a lead wire groove 221, a pair of first mounting holes 315, and a pair of second mounting holes 316. The lead wire groove is formed by the first side surface 313 recessed towards the second side surface 314. The pair of first mounting holes 315 extend from the bottom surface 311 to the top surface 312, and the pair of second mounting holes 316 extend from the bottom surface 311 into the lead wire groove 221. The lead wire groove 221 can be used to receive the lead wire of the ultrasonic atomizing sheet 21.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, the base body 31 is provided with a protrusion, which is used to limit the assembly of the base and the atomizing shell. The protrusion extends outward in the circumferential direction along the outer wall surface of the base body 31 and is used to limit the assembly of the base 3 and the atomizing shell 1. The mounting groove 321 is formed in the bracket 32 ​​of the base 3.

[0045] In some embodiments, the protrusion includes a first protrusion 3110 and a second protrusion 3120 disposed opposite to each other. The first protrusion 3110 extends outward along the edge of the bottom surface 311, and the second protrusion 3120 extends outward along the edge of the top surface 312. A limiting groove 3111 is formed between the first protrusion 3110 and the second protrusion 3120.

[0046] The pair of first mounting holes 315 allow the magnetic suction member 7 to be installed and also serve as injection holes, communicating with the liquid storage chamber 13. The liquid-generating matrix can be injected through the first mounting holes 315, minimizing the external force on the atomizer 10. After injection, the sealing plug 9 is inserted and the magnetic suction member 7 is installed, effectively reducing leakage compared to existing injection methods. The pair of second mounting holes 316 allow the electrode 6 to be installed, with the pair of first mounting holes 315 respectively located on both sides of the pair of second mounting holes 316. In some embodiments, the atomizer 10 further includes a sealing plug 9, which is detachably installed in the first mounting hole 315 to seal the first mounting hole 315 and prevent leakage. The magnetic suction member 7 can be installed in the first mounting hole 315, located at the end away from the liquid storage chamber 13 and abutting against the sealing plug 9. Correspondingly, the fixed cover 8 is also provided with a third mounting hole 81 and a fourth mounting hole 82, which correspond to the first mounting hole 315 and the second mounting hole 316, respectively.

[0047] In some embodiments, the bracket 32 is provided with a mounting groove 321 for mounting the ultrasonic atomization piece 21. The bottom surface of the mounting groove 321 is formed with a bottom wall for supporting the ultrasonic atomization piece 21, so that the ultrasonic atomization piece 21 can be placed relatively stably and conveniently positioned. When the base 3 is mounted on the atomization shell 1, the mounting groove 321 is opposite to the mist outlet 111, so that the aerosol generated by the ultrasonic atomization piece 21 mounted in the mounting groove 321 can be discharged from the mist outlet 111.

[0048] As shown in Figure 6 some embodiments, the bottom wall of the mounting groove 321 is provided with a liquid guide hole 3211 that is in communication with the liquid storage cavity 13. The liquid guide hole 3211 can be used to guide the liquid atomization substrate in the liquid storage cavity 13 to the ultrasonic atomization piece 21 for atomization.

[0049] For reference Figure 4 together, in some embodiments, the ultrasonic atomization piece 21 can be mounted in the mounting groove 321 of the base 3. In some embodiments, the ultrasonic atomization piece 21 includes an atomization piece body 211 and a solder pad 212. The line connecting the solder pad 212 and the center point of the ultrasonic atomization piece and the perpendicular line between the plane where the base body is located and the center point have an included angle a. In the present embodiment, the number of solder pads 212 is one pair. The atomization piece body 211 can be in the shape of a circular sheet in some embodiments. The one pair of solder pads 212 are mechanically and electrically connected to the atomization piece body 211, respectively, to be connected to the positive and negative electrodes of the power supply assembly, respectively. When the ultrasonic atomization piece 21 is placed in the mounting groove 321, the solder pads 212 are placed at an angle, so that the ultrasonic atomization piece 21 as a whole is close to the bottom surface 311 of the base body 31, and the wire hiding space at the bottom of the ultrasonic atomization piece 21 is fully utilized, which reduces the center height of the ultrasonic atomization piece 21 and reduces the amount of residual liquid. In some embodiments, the included angle a between the line connecting the solder pad 212 and the center point of the ultrasonic atomization piece and the perpendicular line between the plane where the base body is located and the center point is 0-90 degrees; preferably, 10-45 degrees.

[0050] In some embodiments, the atomizer 10 further includes a sealing cover 4 for plugging the mist outlet 111. The sealing cover 4 can be detachably mounted in the mist outlet 111 of the atomization shell 1. In some embodiments, the sealing cover 4 can be made of plastic, rubber, silicone or the like. The sealing cover 4 can further improve the sealing performance and reduce the probability of liquid leakage during storage and transportation.

The integrally formed first sealing member 5 can save the amount of materials, and is convenient to assemble, thereby saving costs. In some embodiments, the first sealing part 51 can be annular, and the second sealing part 52 can be disc-shaped. The first sealing part 51 cooperates with the base body 31, the first sealing part 51 can be clamped in the limiting groove 3111 formed in the base body 31, and the first sealing part 51 abuts against the atomization shell 1 to play a sealing role. The limiting groove 3111 can limit the axial movement of the first sealing member 5 to prevent it from falling off; at the same time, the first sealing member 5 installed in the limiting groove 3111 can also cover the electrode 6 arranged on the base 3 to prevent it from being exposed. The second sealing part 52 cooperates with the support 32 of the base 3, the second sealing part 52 can seal the edge of the ultrasonic atomization piece 21, and the second sealing part 52 has air holes 521 for cooperating with the ultrasonic atomization piece 21 to generate mist.

[0053] In some embodiments, the second sealing part 52 further comprises a limiting part 53 extending downward along the second sealing part 52, and the limiting part 53 tightly cooperates with the outer wall of the support 32 of the base 3.

[0054] In some embodiments, the first sealing member 5 can be made of silica gel or other materials, which has elasticity to facilitate the sealing process. In some embodiments, the shape and size of the first sealing member 5 are comparable to those of the base 3, so that the first sealing member 5 and the base 3 can tightly cooperate.

The shape and size of the second sealing member 22 are comparable to those of the mounting groove 321, so that the second sealing member 22 and the mounting groove 321 are adapted. In some embodiments, the second sealing member 22 can be made of silica gel or other materials.

[0056] The second sealing member 22 is formed with a protrusion which is tightly matched with the support 32 of the ultrasonic atomizing piece 21, so that the sealing performance is good, and a through hole 222 is formed in the middle of the bottom of the second sealing member 22, which corresponds to the liquid guide hole 3211 of the mounting groove 321, so that the liquid atomizing base in the liquid storage cavity 13 can be guided to the ultrasonic atomizing piece 21.

[0057] As shown in Figures 1 to 6 some embodiments, the atomizer 10 further comprises a fixed cover 8 which is detachably connected to the atomizing shell 1 and can cover the side wall of the base body 31. The fixed cover 8 can be made of metal material in some embodiments, such as SPCC or aluminum alloy.
