Description
Technical Field
The invention relates to a foam generator for a squeeze container, in particular to a squeeze foam pump.
Background
The foam pump is a package of common daily chemical cleaning products, and is used by mixing liquid and gas containing foaming agent through pressure to form foam through internal structural design and uniformly refining the foam through a filter screen to flow out.
The general basic structure of a foam pump is to have an air chamber that provides the gas required to mix the foam and a liquid chamber that provides the liquid required to mix the foam, and a pressure source that provides the gas and liquid required to mix the foam, and channels that mix the gas and liquid required for the foam. The patent of various foam pumps is to generate unique structures and performances of the respective foam pumps through different designs of the general basic structures;
the foam pump products commonly used are push-type foam pumps, which require the pump head of the foam pump to be pushed first to pump the foam to the hand and then to use the foam on the hand. The push type foam pump is generally formed by combining a plurality of parts, the main body of the pump is a large cylinder, a small cylinder, a large piston and a small piston, the large cylinder forms an air cavity of the foam pump, the small cylinder forms a liquid cavity of the foam pump, the large cylinder is matched with the large piston to provide a gas pressure source for an air passage, the small cylinder is matched with the small piston to provide a liquid pressure source, a unidirectional circulation passage is arranged in the piston to form a passage for mixing gas and liquid required by foam, a push nozzle is connected to the piston passage, the air passage and the liquid passage are converged to the same foam outlet to be mixed into foam, the foam is uniformly refined through a filter screen, and finally the foam flows out of the push nozzle for use.
The push type foam pump has simple structure, but is inconvenient to use, and has the following problems:
when the foam-discharging device is used, the liquid container is fixed firstly, then the pressing nozzle is pressed to discharge the foam, the operation usually needs two hands, one hand is used for fixing the liquid container and pressing the pressing nozzle, and the other hand is used for connecting the foam, so that the use is inconvenient;
in order to ensure that the piston driven by the pressing nozzle can smoothly return to the original position after being pressed, the piston is reset by spring force, and in order to ensure the sealing between the cylinder and the piston, the cylinder and the piston form tight fit, so that the relative motion resistance between the cylinder and the piston is very large, the spring force required for resetting the piston is relatively large, the force required for pressing the pressing nozzle is relatively large, and the use is inconvenient;
the use process is to take bubbles firstly and then smear the bubbles, so that the bubbles can not be taken and smeared at the same time, and the use is inconvenient;
the scheme of an extrusion type foam pump is proposed in the Chinese patent application number 201410574155.6, but the scheme needs to assist the use of the foam pump by relying on the fact that a container matched with the foam pump has the functions of extrusion and resetting, and the extrusion type foam pump cannot independently have the function of converting foam, so that the use is very inconvenient.
The published Chinese patent application number 201710816100.5 also proposes a scheme of an extrusion type foamer, wherein a pressing main body is arranged, two independent air cavities and liquid cavities are isolated on the pressing main body through a baffle plate, and independent pressing glue is arranged on the air cavities and the liquid cavities, so that the pressures of the air cavities and the liquid cavities cannot be consistent and coordinated, and gas and liquid are difficult to foam when mixed;
this scheme sets up air cavity and liquid chamber directly in pressing the main part to all be provided with on air cavity and liquid chamber and press the glue, this just causes two kinds of possibilities: firstly, when the liquid fails to fill the liquid cavity mostly, the liquid cavity is extruded and air at the upper part of the liquid cavity is discharged, and liquid cannot be discharged to form foam; secondly, when most of liquid fills the liquid cavity, the extrusion glue on the liquid cavity and the air cavity can have soft air cavity and hard liquid cavity due to the large density difference between the gas and the liquid, so that the use effect is poor;
this scheme sets up the liquid chamber in pressing the main part, because the gas-liquid mixture that produces the foam needs more air, causes to press the main part great, therefore presses the liquid chamber in the main part also can be great, and this will cause the liquid chamber to be full of liquid and need more pressing times, consequently when the extrusion type foamer of this structure is used for the first time, need press many times and extrude the foam, causes the use difficulty.
