Some embodiments according to the present invention are described below with reference to fig. 1 to 7.

As shown in fig. 1 to 6, an embodiment according to a first aspect of the present invention provides a two-phase showerhead 10, including: a liquid cap 102, a gas cap 104, and a connector 106. The connector 106 is removably connected to the liquid cap 102. The connecting member 106 is provided with a stopper 1064, and the stopper 1064 is used for pressing the gas cap 104 against the liquid cap 102.

In this embodiment, the connector 106 is provided so that the connector 106 is detachably connected to the liquid cap 102, and the gas cap 104 is pressed against the liquid cap 102 via the stopper 1064, whereby the gas cap 104 can be removed and the liquid cap 102 can be exposed when the connector 106 is removed. Similarly, during installation, the gas cap 104 can be fixed by first aligning the gas cap 104 with the liquid cap 102 and then connecting the connector 106 with the liquid cap 102. The two-phase spray head 10 of the embodiment has the advantages of simple structure, easy assembly and disassembly, high assembly and disassembly speed, convenient maintenance of the liquid cap 102 and the gas cap 104, and independent cleaning and maintenance of the liquid cap 102 and the gas cap 104 after the two-phase spray head is taken down, thereby improving the convenience of maintenance and cleaning. In addition, it should be noted that the limiting portion 1064 of the connecting member 106 crimps the gas cap 104 to the liquid cap 102, and this crimping manner is also beneficial to improve the sealing performance between the gas cap 104 and the liquid cap 102.

As shown in FIGS. 4 and 6, the gas cap 104 is generally conical and has a skirt 1044 such that the retaining portion 1064 compresses the skirt 1044 against the liquid cap 102. A tapered gas cap 104 whose tip facilitates spraying out of the connector 106. The tapered gas cap 104 may also form an aerosolizing space with the liquid cap 102.

In the above embodiment, in both the connector 106 and the liquid cap 102, the connector 106 is provided with the catching groove 1060. The liquid cap 102 is provided with a clamping member 1020. The connector 106 and the liquid cap 102 are connected by the engagement of the engaging groove 1060 and the engaging member 1020.
