The front block 39 match the notches 47 and are intended to mount the seal ring 30. Front lugs 41 are respectively disposed on the two front mounting portions 35. Front through holes 42 are disposed on the front lugs 41.

The atomizing rear casing 29 comprises a rear body 36 and two rear mounting portions 37 formed on the left and right sides of the rear body 36. The rear body 36 and the two rear mounting portions 37 are formed integrally or separately. A left spring piece 32a and a right spring piece 32b are mounted to two rear mounting portions 37 respectively. Two spring piece outlets 33 correspond to the left spring piece 32a and the right spring piece 32b respectively. Rear lugs 43 are disposed on the rear body 36.

Thus, the atomizing front casing 28 and the atomizing rear casing 29 are detachable to make for repair and replacement of the atomizing module and lengthen service life.

As shown in FIG. 4 and FIG. 11, the battery device 16 comprises a battery box 55 mounted inside a battery groove 14b, a substrate 56 mounted to one side face of the battery box 55, and two electrodes 57. The substrate 56 is electrically connected to the battery box 55. A button 59 and two conductive springs 58 are disposed on the substrate 56. One end of the button 59 is contained in a mounting hole 60 of the body housing 11. The two electrodes 57 are respectively mounted inside a placing groove 14a. As shown in FIG. 6, one ends of the two electrodes 57 are respectively connected to the two conductive springs 58 in an abutted manner and the other ends run through two spring piece openings 33 and are connected to the left spring piece 32a and the right spring piece 32b in an abutted manner. Through the abutted connection between the two conductive springs 58 and the two electrodes 57, and between the two electrodes 57 and the left spring piece 32a and right spring piece 32b, a channel is formed between the substrate 56 and the seal ring 31 so that the high frequency current generated by the substrate 56 can be transferred to the atomizing piece 31 and the atomizing piece 31 generates high frequency vibration.

In this embodiment, the battery box 55 comprises a body 61, batteries 62 inside the body 61, and two battery chips 63a and 63b. The two battery chips 63a and 63b are respectively connected to an anode and a cathode of the batteries 62. In this embodiment, the batteries 62 are three 3A batteries and replaceable, as shown in FIG. 3. Through the two battery chips 63a and 63b, the three batteries 62 realize series connection and power supply to the substrate 56.

Working principle of the present invention: When the button 59 is pressed, the battery 62 will supply power to the substrate 56. As the two conductive springs 58 are connected to the two electrodes 57, and the two electrodes 57 are connected to the left spring piece 32a and the right spring piece 32b, the high frequency current generated by the substrate 56 is transferred to the atomizing piece 31. The atomizing piece 31 then generates high frequency vibration. On the one hand, the high frequency vibration of the atomizing piece 31 pats the contacted liquid flowing into the diffusion orifice 18 from the water tank body 21 and splits it into tiny misty particles. On the other hand, the high frequency vibration of the atomizing piece 31 will generate certain push on its surface, thereby pushing the generated misty particles to the diffusion orifice 18 and the connecting hole 66, eventually pushing it out of the mist discharge orifice 17 into the air and achieving the function of fumigating and moisturizing.
