Figure 8 As shown,

[0039] The outer cover 1 is provided with a hook as a support point, so that the head cap cannot be pressed down.

[0040] As shown, Figure 10 And 11 The pump core assembly 3 adopts an existing structure design, which is provided with pump core assembly first buckle 301, pump core assembly sealing surface 302 and pump core assembly second buckle 303. Figure 12 And 13 The head cap buckle 201 is sealingly matched with the pump core assembly second buckle 303, and the head cap positioning rib 202 is positioned and matched with the large circle positioning groove 508.

[0041] As shown, Figures 14-16 The large circle 5 is installed on the inner bottle opening, and together with the head cap 2, the pump core assembly 3 and the gasket 4, forms a spray head assembly. The large circle 5 is provided with large circle buckle 501, large circle sealing rib 502, large circle limiting surface 503 and large circle positioning groove 508.
