The PVDF material has a good resistance to ultraviolet ageing, so that the service life of the connector 9 can be prolonged.
The cavity wall of the inner cavity 12 and its peripheral components are generally made of plastic, which is greatly affected by the aging of ultraviolet light. In the process of taking out and putting back the liquid containing cavity 6 into the content cavity 12 and in the process of placing the liquid containing cavity outside the content cavity 12, if the ultraviolet germicidal lamp 7 is in an on state, an aging effect is generated on the ultraviolet irradiation to the content cavity 12 so as to shorten the service life of the content cavity 12, and in addition, the ultraviolet irradiation can cause damage to the irradiated human body.
In order to reduce the ageing of the ultraviolet rays on the wall or peripheral parts of the inner chamber 12 of the sterilizing device 4 and the damage to the human body, the atomizing working part 1 of the present invention is provided with a signal sensing member (not shown in the drawing) on the atomizing working part 1 located outside the liquid accommodating chamber 6, a signal triggering member 64 for triggering the signal sensing member is provided on the liquid accommodating chamber 6, and a central controller (not shown in the drawing) is further included, the ultraviolet sterilizing lamp 7 is controlled by the central controller, the signal sensing member is in signal connection with the central controller, and the central controller is used for triggering the signal of the signal sensing member in response to the signal triggering member 64 when the liquid accommodating chamber 6 is placed in the inner chamber 12 so as to control the operation of the ultraviolet sterilizing lamp 7. Wherein according to this solution, the signal sensing member is provided on the atomizing working part 1 at a position in the vicinity of the outside of the liquid containing chamber 6, and is also a position which is convenient to provide and facilitate cooperation with the signal triggering member 64, for example, the signal sensing member is provided on the wall of the content chamber 12.

Of course, other waterways for implementing the water inlet and outlet of the sterilization chamber 12 may be adopted in the atomizing device of the present invention.
Further, a seal ring 67 is provided at least on the open portion 63. The sealing ring 67 may be an annular sealing ring, or may be a part of a sealing member, where the sealing member is an integral structure, and the sealing member wraps the outer side wall, the top wall and the opening 63 of the metal cover frame 65.
