The utility model also discloses an extrusion formula foam pump, including pump body 1, be equipped with gas-liquid mixing chamber 2, gas passage 3, liquid channel 4 and play bubble mouth 5 in the pump body 1, the one end of gas passage 3 and liquid channel 4's one end all communicate with the one end of gas-liquid mixing chamber 2, the other end of gas passage 3 is equipped with keeps apart chamber 6, be equipped with first gas pocket 61 on the chamber wall of keeping apart chamber 6, the other end of gas passage 3 and first gas pocket 61 all communicate with keep apart chamber 6, go out bubble mouth 5 and 2 other ends of gas-liquid mixing chamber intercommunication.

Specifically, the container 14 that this packaging container adopted can be by extrusion deformation, and can leave 30% space in general container 14 and do not adorn the fluid, pump body 1 installs on the container, when extrusion container 14, the inside pressure increase of container 14, fluid in the container 14 passes through liquid passage 4 and gets into gas-liquid mixing chamber 2, gas in the container 14 gets into isolation chamber 6 through first gas pocket 61 earlier, later rethread gas passage 3 gets into gas-liquid mixing chamber 2, fluid in gas-liquid mixing chamber 2 forms the foam under gas impact, continue extrusion container 14, the foam is under the effect of pressure, flow out through a bubble mouth 5.

Moreover, when the packaging container is shaken or dropped, the air bubbles can be distributed in the space inside the container 14, if the isolation cavity 6 is not provided, when the container is squeezed for extruding foam, the air channel 3 can be blocked by the air bubbles in the container 14, so that the air in the container 14 cannot enter the gas-liquid mixing cavity 2, and the foam cannot be blown out, so that the fluid is extruded, the function of a foam pump cannot be achieved, and the experience of a user is seriously influenced; then, when the container 14 is released, air sucked into the container from the outside is wrapped by bubbles in the container 14, and fresh air still cannot enter the gas passage 3 and cannot blow out bubbles when the container 14 is pressed.

The foam pump is provided with the isolation cavity 6, if the container 14 is filled with bubbles, the bubbles in the container 14 are generally large due to the small first air hole 61, and the bubbles cannot reach the gas channel 3 through the first air hole 61 of the isolation cavity 6, so that the gas channel 3 cannot be blocked by the bubbles in the container 14 under the isolation effect of the isolation cavity 6, and the gas in the container 14 can smoothly enter the gas-liquid mixing cavity 2 to blow out the foam. And when the air in the container 14 is squeezed and external air needs to be sucked, because a part of the air is stored in the isolation chamber 6 and cannot be wrapped by air bubbles inside the container 14, when the container 14 is squeezed, the air in the isolation chamber 6 can blow the fluid through the air channel 3 at the first time to form foam; even if the air sucked from the outside is wrapped by the air bubbles in the container 14, the generation of foam cannot be influenced, the foam is ensured to flow out during extrusion at every time, the continuity of the extruded foam is ensured, and the use is convenient.

Further, for the foam of extruding is more exquisite, be provided with the net post 10 in the gas-liquid mixing chamber 2, the upper and lower both ends of net post 10 all are equipped with filter screen 11, the outer wall of net post 10 and the lateral wall contact of gas-liquid mixing chamber 2, gas channel 3 intercommunication gas-liquid mixing chamber 2 is located the one end of net post 10 downside.
