The tubular ultrasonic atomizing assembly 100 of the present embodiment is in contrast to the structure of the conventional ultrasonic atomizing assembly 500 shown in fig. 1A-1B:
(1) The atomizing steel sheet 510 and the piezoelectric ceramic body 520 of the existing ultrasonic atomizing assembly 500 are both in a sheet shape and circular, the atomizing steel sheet 510 and the piezoelectric ceramic body 520 are connected up and down, and the atomizing micropore of the atomizing steel sheet 510 is arranged at the center of the annular hole of the piezoelectric ceramic body 520 and only one piezoelectric ceramic body can be arranged. The tubular ultrasonic atomizing assembly 100 of the present invention, as shown in fig. 2-5, has six sides, each of which has a piezoelectric ceramic body 20, and two sides and a top side of which have spray micropores of different shapes, so that the atomizing function and the atomizing effect of the tubular ultrasonic atomizing assembly 100 of the present invention are remarkably superior to those of the conventional ultrasonic atomizing assembly 500.

The conventional ultrasonic atomization assembly 500 cannot be too large in diameter of the piezoelectric ceramic body 520 due to the limitation of the product field Jing Hengxiang, so that the power of the single piezoelectric ceramic body 520 cannot be increased, and only one-way spraying can be adopted.
(3) The tubular ultrasonic atomizing assembly 100 of the present embodiment can completely realize multi-sided multi-directional simultaneous spraying, whereas the conventional ultrasonic atomizing assembly 500 can only realize unidirectional single Kong Weiyi spraying.
(4) The tubular ultrasonic atomizing assembly 100 of this embodiment can realize spray patterns of various shapes, such as top annular spray, side cylindrical multi-point spray and bar spray, while the conventional ultrasonic atomizing assembly 500 cannot realize spray patterns due to limitations of power and structural dimensions.

The piezoelectric ceramic bodies 20 simultaneously resonate at the same frequency to form conjugate resonance, liquid on the inner wall of the side face 11 of the atomizing body is vibrated to form liquid particles, and the liquid particles are ejected from the first spray micropores 13 and the second spray micropores 14 to form water mist.
In this embodiment, when the ultrasonic atomizing apparatus 200 is energized, the high-frequency current negative electrode is conducted through the negative electrodes 120 of the plurality of piezoelectric ceramic bodies 20 on the side of the tubular atomizing body 10, the high-frequency current positive electrode is respectively conducted in parallel with the positive electrodes 110 of the four piezoelectric ceramic bodies 20 on the side surface through the positive electrode communication wires, a potential difference is generated between the positive and negative electrodes of the four piezoelectric ceramic bodies 20 on the side surface, the piezoelectric ceramic bodies 20 convert electric energy into mechanical vibration, so that the tubular atomizing body 10 is driven to integrally form high-frequency conjugate resonance, kinetic energy aggregation occurs in the areas of the top end of the tubular atomizing body 10 and the first group of spray micropores 13 and the second group of spray micropores 14 on the two side surfaces, and the liquid on the surface of the water-guiding cotton 400 is intermittently thrown outwards under high-frequency vibration, so as to form atomization. Specifically, the liquid particles are sprayed out through the second group of spray micropores 14 at the top end to form annular water mist, the liquid particles are sprayed out through the first group of spray micropores 13a at the side surface to form a plurality of cylindrical water mist, and the liquid particles are sprayed out through the first group of spray micropores 13b at the side surface to form strip-shaped water mist.

Therefore, the tubular atomization body is adopted to realize the conjugate resonance function of the multi-surface piezoelectric ceramic body, so that the vibration bandwidth of the whole device is narrowed and the vibration amplitude is increased, the distance and the height of spraying are greatly increased, and the ultrasonic atomization power and the atomization effect can be improved in a relatively small volume in a multiple way.
