Embodiment Construction

[0028] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0029] Such as figure 1 Shown is a schematic diagram of the overall structure of a piston squeeze pump when it is locked. The squeeze pump includes a pump body and a bottle body 7. The pump body includes a press head 1, an outer cover 2, a barrel 3, a piston 4, a piston seat 5, a barrel 6, and a suction pipe 8. All parts of the squeeze pump are plastic parts. Can achieve 100% recyclability and environmental protection.

[0030] The outer cover 2 has an internal thread, and the bottle mouth of the bottle body 7 has an external thread suitable for the internal thread, and the bottle mouth of the outer cover 2 and the bottle body 7 realizes thread-tight connection through the external thread and the internal thread. The bottle body 7 is made of soft material. After the bottle body 7 is pressed, the bottle body 7 will be deformed, and the inner space of t...

Abstract

The invention discloses a piston type extrusion pump. The pump comprises a pump body and a bottle body, the bottle body is used for storing liquid forming foam, the pump body comprises an outer cover, a discharging assembly and a mixing cavity, the outer cover is connected with the bottle body in a sealed manner, a discharging channel used for discharging the foam is formed in the outer cover, and the mixing cavity is installed in the discharging assembly. The end, close to the outer cover, of the discharging assembly is connected with the outer cover and communicated with the discharging channel, the end, away from the outer cover, of the discharging assembly is provided with a liquid inlet channel, the liquid inlet channel extends into the liquid in the bottle body, and the discharging assembly is provided with a liquid inlet channel and an air inlet channel which are not communicated with each other. The liquid inlet channel and the air inlet channel are respectively communicated and connected with the mixing cavity. The liquid and air in the bottle body of the extrusion pump are independent channels before being mixed and do not influence each other, the speed is higher and the mixing efficiency is higher after the liquid and the air are compressed through a gap, in addition, the liquid and the air are mixed twice, and finally foam extruded by the extrusion pump is more uniform and continuous.

Description

technical field [0001] The invention relates to the technical field of extrusion pumps, in particular to a piston type extrusion pump. Background technique [0002] In the prior art, a squeeze pump is a common device and is often used in the field of cosmetics. Common extrusion pumps have valves, and steel balls are generally used in the valves, which is extremely unfriendly to the recycling of subsequent extrusion pumps. In addition, the squeeze pump needs to produce foam, generally because the air in the squeeze pump and the liquid in the squeeze pump are mixed to produce foam, but if the foam is required to be more fine, the mixing efficiency of air and liquid is required to be higher. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a piston squeeze pump, which can solve the problems of recyclability and environmental protection of the squeeze pump, and make the foam produced by the squeeze pump more fine. ...
