Description

Technical Field

[0001] This utility model belongs to the field of emulsion pump technology, and in particular relates to an ultra-thin wall emulsion pump. Background Technology

[0002] As a core functional component of daily chemical packaging, the lightweighting and thinning of emulsion pumps have become an important development trend in the industry. However, the reduction in wall thickness has significantly reduced the mechanical strength of the pump body, making it particularly vulnerable to abnormal user operation, especially violent pressing. This instantaneous and excessive downward pressure can easily cause plastic deformation, cracking, or even breakage of the pump body's chamber and piston tube, resulting in product leakage and permanent functional failure.

[0003] Therefore, designing an emulsion pump with ultra-thin walls that can withstand violent pressing is a problem that needs to be solved by those working in this field. Summary of the Invention

[0004] The purpose of this invention is to provide an ultra-thin-walled emulsion pump. By setting a bypass pressure relief pipe at the bottom of the chamber, it can relieve pressure when the pressure is too high instantaneously, avoiding the impact of violent pressing on the thin-walled chamber and piston tube caused by the sudden increase in pressure. This ensures the strength and service life of the thin-walled emulsion pump. At the same time, the pressure-relieved emulsion is discharged above the liquid surface through the capillary tube, forming an independent pressure relief path that is open to the atmosphere at the end, thus achieving absolute reliability and effectiveness of the pressure relief protection function.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an ultra-thin-walled emulsion pump, comprising a pump cover, a pressure head, a chamber, a piston tube, and a pressure relief mechanism. The chamber is fixed to the bottom of the pump cover. A connecting part is provided at the center of the pump cover. The piston tube passes through the connecting part and the connecting part is sealed. A piston body is provided between the bottom end of the piston tube and the chamber. The pressure head is fixed to the top end of the piston tube. A retainer is provided at the bottom end of the chamber. A suction port is fixed at the bottom end of the chamber. A lower ball bearing is provided between the suction port and the retainer. A main spring is provided between the retainer and the bottom end of the piston tube. An outer guide sleeve is fixed at the top edge of the pump cover, and an inner guide sleeve is fixed at the bottom edge of the pressure head. The bottom end of the inner guide sleeve is concentrically set inside the upper part of the outer guide sleeve and is slidably connected to the outer guide sleeve. Both the piston tube and the chamber are thin-walled tube structures, and the piston tube has an enlarged diameter end at both the bottom and top. The pressure relief mechanism includes a pressure relief tube and a capillary tube. The pressure relief tube includes a large-diameter section and a small-diameter section, and a tapered transition section is formed between the large-diameter section and the small-diameter section. The end of the small-diameter section of the pressure relief tube is connected to the circumferential side of the bottom end of the chamber. The connection point between the pressure relief tube and the chamber is located outside the retainer. The pressure relief tube is inclined downward and connected to the outside of the chamber. One end of the capillary is fixed to the end of the large-diameter section via a connecting plug. A side ball is provided in the transition section, and a secondary spring is fixed between the side ball and the connecting plug. The end of the capillary tube furthest from the pressure relief pipe is fixed to the top of the pump cover via a connecting seat.

[0006] Furthermore, the piston tube has a tapered reinforcing section at its inner top, and an upper ball bearing is provided inside the reinforcing section.

[0007] Furthermore, the pressure head is provided with a liquid outlet pipe on its peripheral side, and the pressure head is provided with a connector end that connects the liquid outlet pipe and the piston pipe.

[0008] Furthermore, the circumferential side of the connector end is provided with an external thread, and an internal threaded sleeve that mates with the thread of the connector end is fixed at the top center of the pump cover.

[0009] Furthermore, the capillary tips are distributed upwards, and a 2-4mm gap is formed between the capillary tips and the pump cover.

[0010] Furthermore, the capillary tube is a rigid plastic tube.

[0011] This utility model has the following beneficial effects: 1. This utility model, by setting a bypass pressure relief pipe at the bottom of the chamber, can relieve pressure when the pressure is too high instantaneously, avoiding the problem of excessive pressure caused by violent pressing, and preventing the pressure from causing a large impact on the thin-walled chamber and piston tube, thus ensuring the strength and service life of the thin-walled emulsion pump. At the same time, the pressure-relieved emulsion is discharged above the liquid surface through the capillary tube, forming an independent pressure relief path that is open to the atmosphere at the end. This physically isolates the pressure coupling with the liquid environment inside the bottle during the pressure relief process, allowing abnormal high pressure to be directly released to the constant atmospheric pressure environment. This absolutely avoids the risk of the bottom inlet valve being opened due to pressure rise inside the bottle, thus achieving absolute reliability and effectiveness of the pressure relief protection function.

[0012] 2. This utility model, through the design of the inner and outer guide sleeves, can guide the pressure head in the vertical direction, ensuring that the pressure head can move straight up and down, resisting the circumferential force on the piston tube when the pressure is tilted, ensuring the performance of the piston tube, and improving its strength and service life.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description
