Inverted type extruding foam pump

Abstract

The invention discloses an inverted type extruding foam pump and relates to the field of pump body structures. The extruding type foam pump is exquisite in structure, easy and convenient to operate, good in stability and free of leakage; and elastic components are replaced with rigid components, so that the machining difficulty is lowered, machining precision is improved, and the material cost islowered. The inverted type extruding foam pump comprises a bottle opening seat, a netted joint, a flow dividing valve, a valve seat, an air supplement control ball, an air outlet control ball, a fixing seat and an air pipe. The bottle opening seat is fixedly connected to a bottom opening of an extruding bottle and internally provided with a liquid outlet and an outer air supplement hole. The netted joint is fixedly connected into the liquid outlet. The flow dividing valve is fixedly connected to the inner side of the liquid outlet and wraps the netted joint, and one or more communicating holesare formed in the top of the flow dividing valve. The valve seat is fixedly connected to the bottle opening seat and sleeves the flow dividing valve. The inverted type extruding foam pump integrallyhas the beneficial effects of being exquisite in structure, easy and convenient to operate, low in assembling difficulty, stable and free of leakage.

Description

technical field [0001] The invention relates to the field of pump body structure, in particular to the improvement of the foam pump therein. Background technique [0002] With the improvement of living standards, people are pursuing convenience in daily life, and daily necessities are also pursuing convenience in use. For example, bottled liquids are generally connected to a liquid pump at the outlet of the bottle. The liquid in the bottle is pumped out. This kind of bottled liquid is liquid when used, such as hand sanitizer, detergent, etc.; but there are still some liquids that need to be kneaded into foam when used. The traditional method is to pump out the liquid and then rub it by hand. It is troublesome to use this way to rub the foam, so people are also studying a new pump that can directly generate foam. [0003] In this regard, the prior art proposes a method such as figure 1 The inverted extruded foam pump is shown, but the opening and closing of the air inlet a...

Problems solved by technology

This kind of bottled liquid is liquid when used, such as hand sanitizer, detergent, etc.; but there are still some liquids that need to be kneaded into foam when used. The traditional method is to pump out the liquid and then rub it by hand. Rubbing foam, this method is more troublesome to use, so people are also researching a new pump that can directly generate foam

[0003] In this regard, the prior art proposes a method such as figure 1 The inverted extruded foam pump is shown, but the opening and closing of the air inlet and the liquid outlet in this type of foam pump are mostly composed of elastic elements such as spring 10. Such elastic elements are prone to failure due to stress fatigue after long-term use. Problems such as resetting or inability to deform; at the same time, affected by its inverted structure, the spring will be soaked in liquids such as hand sanitizer and detergent for a long time, which further reduces the service life of the foam pump

In addition, since the size of this type of foam pump is usually small, the spring, spring seat, gasket seat, and gasket are all very small, and the requirements for the assembled parts are very high, which is very difficult to assemble
