Description

A pump head and container for daily use technical field

The present invention relates to a pump head and a container for daily use, in particular to a pump head for taking out the contents simply, intuitively and conveniently, and a container using the pump head.

Background technique

The pump head is an industrial product that people often use to take out liquid products from containers, such as daily chemical products, food, etc. The existing pump head has many components, and the assembly cost occupies a large proportion in the production cost. However, reducing the number of components requires restructuring the pump head structure, and the research and development cost of the restructuring structure is high, so few people are willing to try it. So, while pump head technology is widely used, there have been few major substantial improvements in pump head structure over the decades.

There may be various materials for the existing pump head, such as plastics, metal springs, glass beads, and various plastics. It is inconvenient to reuse a variety of materials after recycling, which is not conducive to the recycling of materials, and is not conducive to the management of environmental problems such as plastic pollution.

There are still many functional problems in the commonly used pump heads, such as the air tightness is not easy to maintain for a long time, the large spring force affects the controllability, the single extraction volume is too small, and the liquid with high viscous consistency cannot be extracted.

Due to the many reasons mentioned above, pump heads and containers are only simple tools in people's lives, and there are few high-quality or even technological-grade products. With the improvement of people's living standards, people need pump heads and containers with lower manufacturing costs, convenient recycling and better performance, which can improve the operating feel during the taking process and improve the performance of the pump head for taking out fluids.

SUMMARY OF THE INVENTION

In order to solve the above-mentioned problems in the prior art and meet people's needs for a better life, the present invention provides a pump head used in daily life, which includes a piston, and also includes an axial moving component, a liquid suction channel, an outflow channel and a support;

Axial moving assembly, including buffer liquid part, opening part, closed end and sealing part;

The internal space of the buffer liquid part and the opening part is a liquid storage space;

One end of the liquid storage space is closed by the piston, and the other end is closed by the closed end;

The opening is provided with an opening;

According to the order of distance from the piston from near to far, the outlet of the suction channel and the inlet of the outflow channel are sequentially distributed on the side of the opening stroke, and can be communicated with the opening respectively;

The sealing part seals the gap at the joint when the opening is communicated with the outlet of the suction channel or the inlet of the outflow channel;

The movement distance of the opening when it communicates with the outlet of the suction channel and the inlet of the outflow channel respectively is the maximum distance of the reciprocating axial movement of the combination of axial movements;

The bracket prevents the axial moving assembly from continuing to move after the opening communicates with the outlet of the suction channel or the inlet of the outflow channel, respectively, by blocking either end of the axial moving assembly or its outer protruding portion.

The liquid storage space of this axial moving assembly has the function of temporarily storing the liquid to be taken out. One end of the liquid storage space will be closed by the piston, and the liquid will not enter and exit from this end; the other end is closed by the closed end. The buffer liquid part is directly connected with the opening part, and the internal space is communicated. Through the reciprocating movement of the piston, the opening is communicated with the outlet of the suction channel or the inlet of the outflow channel, and then the liquid storage space is sucked in or discharged from the liquid. The bracket blocks any end of the axially moving component (including one end of the buffer liquid part, one end of the closed end) or its outer protruding parts (including but not limited to blocking rings, ridges, chamfers, shoulders, etc.) The axial moving component continues to move after the opening is communicated with the outlet of the suction channel or the inlet of the outflow channel, respectively. Compared with blocking other parts, blocking the two ends does not affect the sealing at the opening, and does not cause the axial moving component to shake greatly.

The liquid buffer portion and the opening portion of the pump head may all be made of transparent materials. The transparent material can show the process of liquid entering the liquid storage space when the piston is pulled out, and flowing out of the liquid storage space when the piston is pushed in, making the removal process more controllable and interesting.

With this pump head, a metering scale can be marked axially on the side wall of the buffer liquid portion. The user can pull out the piston according to the different demand each time, observe the volume of the liquid entering the buffer liquid part, and stop pulling out when the demand is reached; push the piston to the end, and the flow out is the demand. Without the interference of the elastic force of the spring, this kind of pump head has better control feeling and higher accuracy.

In this pump head, the horizontal position of the closed end of the liquid storage space is not lower than the horizontal position of the lowest position of the piston end of the liquid storage space. The closed end of the liquid storage space has a high horizontal position, which is conducive to discharging the air inside the liquid storage space during use, improving the measurement accuracy, and preventing the liquid in the liquid storage space from flowing back from the opening along the suction channel. The axial moving component is placed horizontally or nearly horizontally, which is beneficial to show the process of liquid entering the axial moving component when the piston is pulled away, and flowing out from the outflow channel when the piston is pushed in, increasing the control and fun of the extraction process.

With this pump head, the main body of the outflow channel can be located on the side of the opening of the pump head. The outlet of the outflow channel of the existing pump head is located at the top of the pump head, and is mostly set independently, which wastes materials and space; if it is arranged on the opening side of the pump head, the outflow channel does not need to go around the whole pump head, and the length of the outflow channel is reduced. The length of the main body of the outflow channel is short, which can reduce pressure loss, save materials, and reduce the space occupied by the pump head.

The pump head, the partial outer peripheral surface of the buffer liquid part (including the outer peripheral surface of the main body of the buffer liquid part or the outer peripheral surface of the connection between the buffer liquid part and the opening part) can be provided with a smooth support surface parallel to the axis of the buffer liquid part, the support The face supports the axial reciprocating movement of the axial movement assembly as a whole. After being combined with the peripheral support, the smooth support surface parallel to the axis of the buffer liquid portion supports the axially moving component to move back and forth in a short distance in the axial direction, preventing the non-axial shaking of the axially moving component.

In this pump head, the sealing part can be provided on both sides of the opening. This sealing method is easy to assemble.

In this pump head, the air inlet of the return air passage is covered by the sealing part, and when the piston is pulled out to suck the liquid, the sealing part is removed from the air inlet. Set the air inlet of the return air channel at the position covered by the sealing part, and open the air inlet only when the suction sealing part is removed, which can not only ensure the air return when air needs to be supplemented, but also avoid the liquid to be taken Volatile to prevent outside air from entering the container to oxidize or contaminate the liquid. The other end of the air return channel is communicated with the space above the liquid to be taken.

The present invention also relates to a container comprising a container body and the above-mentioned pump head.

Further, the container body of the container has a plurality of cavities, and each cavity is provided with one of the liquid suction channels. Each cavity is filled with different liquids. When the piston is pulled out to absorb the liquid into the liquid storage space, various liquids will enter; by controlling the diameter of each suction channel at the opening, different liquids can be mixed and taken out in proportion.

This kind of pump head and container This kind of pump head and container overcomes various problems existing in the container of the prior art, and has the advantages of few components, convenient assembly, strong controllability, can take out the contents with high viscosity and consistency, and can be measured out. Etc. At the same time, the material of the pump head and the container is single, which is easy to be recycled and reused, which is beneficial to reduce the pressure of environmental pollution.
