Pump head and container

Abstract

The invention provides a pump head and a container using the same. The pump head comprises a piston, a liquid suction channel, an axial moving assembly, a sealing component, an outflow channel and a support, wherein the axial moving assembly comprises a liquid temporary storage part, an open part and a closed end; the internal spaces of the liquid temporary storage part and the open part form a liquid storage space; one end of the liquid storage space is closed by a piston, and the other end of the liquid storage space is closed by the closed end; the open part is provided with openings; according to the sequence from near to far away from the piston, the outlet of the liquid suction channel and the inlet of the outflow channel are sequentially distributed in the side edge of the opening stroke and can be communicated with the openings; the sealing component seals a gap at a joint formed when each opening is communicated with the outlet of the liquid suction channel or the inlet of the outflow channel; and the movement distance of each opening at the moment when the opening is communicated with the outlet of the liquid suction channel and the inlet of the outflow channel respectively is the maximum distance of axial movement combined with reciprocating axial movement. The container is simple in structure and better in sealing performance; the one-time taking-out amount is larger; the container is suitable for containing articles of daily use, foods and medicines.

Description

technical field [0001] The invention relates to a pump head and a container, in particular to a pump head for taking out contents in a convenient, rapid and large capacity and a container using the pump head. Background technique [0002] The pump head is a product that people often use. The unit price of the existing pump head is not high, but there are many components, and the material cost and assembly cost occupy a large proportion of the production cost. However, reducing the number of components requires reorganization and transformation of the pump head structure, and the research and development cost of the recombination structure is high, so few people are willing to try it. Therefore, although the pump head technology is a traditional technology with wide application and mature production technology, the structure of the pump head has rarely been substantially improved for decades. [0003] There may be many kinds of materials for the existing pump head, such as ...

AI Technical Summary

Problems solved by technology

It is inconvenient to disassemble and recycle various materials after recycling, which is not conducive to the recycling of materials, and is not conducive to the treatment of environmental problems such as plastic pollution.

[0004] There are still many functional problems in the commonly used pump heads, such as the airtightness is not easy to maintain for a long time, the spring elasticity affects the controllability, the volume of a single pump is too small, and the viscous liquid cannot be pumped out, etc.
