[0025] In the embodiment, preferably, the pumping mechanism 103 further includes pump cylinder 204, the pump cylinder 204 bottom end fixed mounting has connecting cylinder 205, the connecting cylinder 205 inside fixed mounting has suction pipe 206.

[0026] Through the above scheme, the liquid can be stored by the pump barrel, the suction pipe can be connected by the connecting barrel, and the liquid can be sucked into the pump barrel by the suction pipe.

[0027] In this embodiment, preferably, the pump barrel 204 is fixedly installed with a limiting plate 301 at the top end, the limiting plate 301 is fixedly installed at the top end inside the hollow screw cap 106, and the first recess 302 is formed on the outside of the hollow screw cap 106.

[0028] Through the above scheme, the hollow screw cap can be installed to assemble the whole pump head with the bottle mouth, the whole pump head can be assembled by screwing the hollow screw cap with the bottle mouth, and the first recess can increase the friction of the hollow screw cap to facilitate the user to screw.

[0029] In this embodiment, preferably, the hollow screw cap 106 is fixedly installed with a clamping barrel 303 at the top end, the clamping barrel 303 is movably installed on the outside of the pressing pipe 104, and the second recess 304 is formed on the outside of the clamping barrel 303.

[0030] Through the above scheme, the second recess can increase the friction of the clamping barrel, thereby facilitating the user to disassemble and assemble.

[0031] In this embodiment, preferably, the clamping barrel 303 is fixedly installed with a fixed threaded pipe 305 at the bottom end, the fixed threaded pipe 305 penetrates through the hollow screw cap 106 and is fixedly installed at the top end inside the pump barrel 204, and the hollow piston 201 is movably installed inside the pump barrel 204.

[0032] Through the above scheme, the fixed threaded pipe penetrating through the hollow screw cap can be connected with the pump barrel, the piston can be limited in the pump barrel, and the hollow screw cap can be clamped at the top end of the limiting plate.

[0034] Through the above scheme, the hollow piston can be driven to rise when the user releases the pressing head by the spring compression and rebound, so that the pump barrel can be driven to generate negative pressure by the hollow piston, the second plug ball can be limited by the limiting clamp, and the bottom end of the pump barrel can be blocked when high pressure is generated in the pump barrel by the second plug ball.

[0035] The reusable pump head of the embodiment is assembled with the bottle body when the hollow nut 106 and the bottle mouth are clamped and screwed to place the pump cylinder 204 and the suction pipe 206 in the bottle, so that the whole pump head is assembled with the bottle body. After the assembly is completed, the user presses the pressing head 101 to make the pressing pipe 104 be pressed, and the hollow piston 201 is pressed in the pump cylinder 204 to compress the spring 306. When the hollow piston 201 is pressed downward, the air in the pump cylinder 204 is extruded into the pressing pipe 104 and the first blocking ball 203 is lifted from the inclined block 202, and the air extrusion makes the second blocking ball 402 be compressed to close the bottom end of the pump cylinder 204, so that the air can only pass through the pressing pipe 104 into the pressing head 101 and be discharged through the liquid outlet pipe 102. After the air is discharged, the pressing head 101 is loosened, so that the spring 306 is not pressed to rebound and drive the hollow piston 201 to move upward. When the hollow piston 201 moves upward, the negative pressure is generated in the pump cylinder 204, the first blocking ball 203 is tightly sucked on the inclined block 202 to close the pressing pipe 104, and the second blocking ball 402 is lifted in the limiting clamp 401, so that the liquid in the bottle can be sucked into the pump cylinder 204 through the suction pipe 206 by the negative pressure. When the liquid fills the pump cylinder 204, the user presses the pressing head 101 again to make the liquid in the pump cylinder 204 enter the pressing pipe 104 to lift the first blocking ball 203 again, so that the liquid can enter the pressing head 101 and be discharged through the liquid outlet pipe 102. When the liquid in the pump cylinder 204 is discharged, the pressing head 101 is loosened, the negative pressure is generated in the pump cylinder 204 again, the liquid in the bottle enters the suction pipe 206 through the negative pressure and lifts the second blocking ball 402 to enter the pump cylinder 204 to complete the liquid supplement.
