The invention also discloses an extrusion type foam pump, which comprises a pump body 1, wherein a gas-liquid mixing cavity 2, a gas channel 3, a liquid channel 4 and a foam outlet 5 are arranged in the pump body 1, one end of the gas channel 3 and one end of the liquid channel 4 are both communicated with one end of the gas-liquid mixing cavity 2, the other end of the gas channel 3 is provided with an isolation cavity 6, a first air hole 61 is arranged on the cavity wall of the isolation cavity 6, the other end of the gas channel 3 and the first air hole 61 are both communicated with the isolation cavity 6, and the foam outlet 5 is communicated with the other end of the gas-liquid mixing cavity 2.
Specifically, the container 14 adopted in the packaging container can be extruded and deformed, and 30% of the space in the container 14 is reserved without containing fluid, the pump body 1 is arranged on the container, when the container 14 is extruded, the pressure in the container 14 is increased, the fluid in the container 14 enters the gas-liquid mixing cavity 2 through the liquid channel 4, the gas in the container 14 firstly enters the isolation cavity 6 through the first air hole 61, then enters the gas-liquid mixing cavity 2 through the gas channel 3, the fluid in the gas-liquid mixing cavity 2 forms foam under the impact of the gas, the container 14 is continuously extruded, and the foam flows out through the foam outlet 5 under the action of the pressure.
Moreover, when the packaging container is shaken or falls down, bubbles can be distributed in the space inside the container 14, if the isolation cavity 6 is not provided, when the container is extruded for extruding foam at the moment, the bubbles in the container 14 can block the gas channel 3, so that the gas in the container 14 cannot enter the gas-liquid mixing cavity 2 and cannot blow out the foam, the extruded fluid cannot reach the function of a foam pump, and the experience of a user is seriously affected; 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 when the container 14 is squeezed, so that bubbles cannot be blown out.
If the foam pump is provided with the isolation cavity 6, if the air bubbles are fully distributed in the container 14, the air bubbles in the container 14 are generally larger because the first air holes 61 are smaller, and the air bubbles can not reach the air channel 3 through the first air holes 61 of the isolation cavity 6, so that the air channel 3 can not be blocked by the air bubbles in the container 14 under the isolation action of the isolation cavity 6, and the air in the container 14 can smoothly enter the air-liquid mixing cavity 2 to blow out the foam. When the gas in the container 14 is squeezed each time and external air is required to be sucked, as a part of gas is stored in the isolation cavity 6 and cannot be wrapped by bubbles in the container 14, when the container 14 is squeezed, the gas in the isolation cavity 6 can blow the fluid through the gas channel 3 at the first time to form foam; even if the air sucked from the outside is wrapped by the bubbles in the container 14, the foam generation is not affected, the foam outflow is ensured for each extrusion, the continuity of the extruded foam is ensured, and the use is convenient.
Further, in order to make the foam of extruding finer and smoother, 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, the one end that gas channel 3 even gas-liquid mixing chamber 2 is located net post 10 downside. Moreover, the mesh openings of the mesh screen 11 at the upper end of the mesh column 10 are smaller than those of the mesh screen 11 at the lower end, and the fluid and the gas are mixed at one end of the gas-liquid mixing chamber 2 at the lower side of the mesh column 10 to form foam with relatively large bubbles, the foam passes through the mesh screen 11 at the lower end to form foam with small bubbles, and the foam passes through the mesh screen 11 at the upper end to form foam with smaller bubbles.
Moreover, in order to prevent the fluid from flowing back into the container when the container is released, the next time it is still required to squeeze the fluid several times to press it into the gas-liquid mixing chamber 2. One end of the liquid channel 4 is provided with a liquid separating clamping position 41, and a liquid separating component 42 is arranged in the liquid separating clamping position 41. When the container is extruded, fluid can enter the gas-liquid mixing cavity 2 through a gap between the liquid separation clamping position 41 and the liquid separation component 42; when the container is released, the liquid separating member 42 blocks the liquid separating stopper 41, and fluid is prevented from flowing back to the container. Moreover, the liquid separating member 42 can also play a role of dividing, and the large liquid flow is changed into a fine liquid flow through the gap between the liquid separating clamping position 41 and the liquid separating member 42, and enters the gas-liquid mixing cavity 2. The contact area between the fluid flowing into the gas-liquid mixing chamber 2 from the liquid channel 4 and the gas flowing into the gas-liquid mixing chamber 2 from the gas channel 3 is increased, and the uniformity and fineness of the blown foam are increased.
Referring specifically to fig. 2, one of the liquid separation clamping position 41 and the liquid separation component 42 is configured such that an upper clamping portion 43 and a lower clamping portion 44 are respectively disposed on sidewalls of upper and lower ends of the liquid separation clamping position 41, and the liquid separation component 42 is a split glass bead, and the split glass bead is disposed between the upper clamping portion 43 and the lower clamping portion 44.

The liquid separation clamping position 41 is positioned at the lower side of the net column 10. In this way, the fluid in the container 14 is divided into small liquid flows after passing through the liquid separating clamping position 41, the small liquid flows into the gas-liquid mixing cavity 2, the gas in the container 14 enters the gas-liquid mixing cavity 2 through the gas channel 3, the fluid and the gas are mixed to form foam, and the foam is extruded to the foam outlet 5 through the filter screen 11.
When the container 14 is squeezed, fluid in the container enters the liquid channel 4 under the pressure, and rushes out the split glass beads to enter the gas-liquid mixing cavity 2. When the container 14 is released, a negative pressure is generated inside the container, and the split beads block the funnel ring under the suction of the negative pressure, so that the fluid or foam is prevented from flowing back to the container.
Referring to fig. 3 again, another structure of the liquid separation clamping position 41 and the liquid separation component 42 is that a liquid groove 45 is arranged on the side wall of the liquid separation clamping position 41, the liquid separation component 42 is a flow separation column, and the flow separation column is arranged in the liquid separation clamping position 41.
