The first object includes a connection channel and a sliding slot perpendicular to the connection channel. A retaining wall and a plug-in channel are provided between the sliding slot and the connection channel. An insertion buckle is provided with a buckle body slidable in the sliding slot and an insertion piece adapted to be inserted in or retracted from the connection channel through the plug-in channel. The second object is inserted into the connection channel and is provided with a recess matching the insertion piece. The spray shower includes the connection mechanism. The connection structure and the spray shower are mechanically connected.

Disclosed is a needle-type vibrate-to-nebulize apparatus and nebulizer for nebulizing fluids, in particular essential oils. The needle-type vibrate-to-nebulize apparatus mainly comprises the air passage designed in the module, the steel needle and the vibrating unit. Fluid is delivered from the rear end to the front end, then nebulized at the front end by high-frequency vibration. The nebulized mist is blown out through the air passage. The nebulizer mainly comprises the needle-type vibrate-to-nebulize apparatus and the peristaltic pump with rollers. The peristaltic pump with rollers is capable of sucking and supplying essential oil to the steel needle, as well as reversing the oil back when power off to prevent clogging. High-frequency vibrating action of the vibrating unit is generated by the piezoelectric disk and induced to the steel needle. As a result of resonation, essential oil is nebulized at the front end and blown out through the air passage.

The invention provides a head for a fluid excitation device in which a transducer comprising a vibration generation portion and a fluid excitation portion is secured to a flexible substrate using an adhesive layer located between the vibration generation portion and the flexible substrate. An external force-applying structure is not needed to secure the vibration generation portion to the fluid excitation portion, removing a cause of significant vibration damping. Rather than damping the vibrations generated by the transducer, the flexible substrate instead itself moves in co-operation with the transducer, reducing damping effects. The design and manufacture of this arrangement is relatively simple and no complex tuning is required to ensure efficient operation over the entire operational life of the head. The head can be used in a fluid excitation device such as an atomiser or ultrasonic bath.

A power supply and a control module are disposed on a machine body of the atomization machine. When the atomization bottle is coupled with the atomization machine, the atomizer can be activated by the control module to generate a mist. After the liquid in the atomization bottle is used up, the atomization bottle can be replaced by a new atomization bottle.
