The current fixing method of the fasteners in the nozzle is not only time-consuming and labor-intensive, but also complicated in the disassembly and assembly process.

[0030] An embodiment of the present invention provides a single-hole nozzle assembly, including a nozzle body 1 and a delivery pipeline 2, wherein the input end of the nozzle body 1 is sleeved with a male buckle component 4, and the output end of the delivery pipeline 2 is sleeved with a female buckle component 3, an insert 42 is formed on the male buckle component 4, and a slot 32 is formed on the female buckle component 3, the insert 42 matches the slot 32, and after the insert 42 is inserted into the slot 32, it is fixed by adsorption by a magnet, so that the male buckle component 4 is connected to the female buckle component 3.

Epoxy resin also has good electrical insulation properties and is suitable for bonding and sealing electronic components (piezoelectric ceramic tube 22).

[0039] The installation method of the single-hole nozzle assembly of this embodiment includes the following steps:

[0040] Clamp the male buckle component 4, insert the insert 42 into the slot 32, and the female buckle component 3 absorbs the male buckle component 4 through the magnet;

[0041] After the female buckle component 3 absorbs the male buckle component 4, the nozzle body 1 is aligned with the delivery pipeline 2, and the connection is completed, thereby completing the installation.

[0042] The installation method of this embodiment is based on the cooperation between the female buckle component 3 and the male buckle component 4 provided with magnets, which can achieve self-guided connection during installation, significantly improving the installation efficiency; at the same time, the female buckle component 3 and the male buckle component 4 are self-guided and connected through the adsorption effect of the magnet, thereby achieving liquid communication between the nozzle body 1 and the delivery pipeline 2.
