Description

Technical Field

[0001] The utility model relates to the technical field of PE bottles, in particular to a corrosion-resistant PE bottle structure with an exhaust component. Background Art

[0002] In the plastic bottle packaging industry, polyethylene (PE) bottles are widely used in the packaging of various liquid products due to their excellent low temperature resistance, chemical stability, non-toxicity and odorlessness. However, with the continuous increase in market demand for product packaging, the traditional PE bottle structure has gradually failed to meet the requirements of use in some special scenarios, especially in applications that require long-term storage of corrosive liquids or high-pressure gases.

[0003] The reference patent name is corrosion-resistant PE bottle structure with limiting assembly (publication number CN220555434U). By setting a limiting structure, the control block is rotated to drive the worm and the worm wheel to drive the driving shaft to rotate, thereby driving the concave-convex turntable to rotate. During the rotation, the concave-convex turntable drives the circular block to cooperate with the connecting rod to drive the driving block to slide above the surface of the PE bottle body, and drives the support block to squeeze the first spring. At this time, one end of the driving block extends to the outside of the PE bottle body, and then the screw is rotated to cooperate with the wedge block to drive the limiting block to slide on the outer surface of the limiting rod and stretch the second spring, so that the bottom end of the limiting block contacts the placement table, thereby increasing the friction with the table through the concave-convex surface set at the bottom, so as to limit the PE bottle body and improve its stability.

[0004] When storing corrosive liquids, the traditional PE bottle structure may generate gas inside the bottle due to the volatilization of the liquid or temperature changes. If these gases cannot be discharged in time, it may not only cause the pressure inside the bottle to increase, increasing the risk of bottle rupture, but also affect the quality and stability of the liquid. In addition, the storage of high-pressure gas also faces similar problems. Excessive pressure may not only damage the bottle body, but also cause safety hazards. The prior art is similar to the above patents and lacks a structure for exhausting the inside of the PE bottle. For this reason, the utility model provides a corrosion-resistant PE bottle structure with an exhaust component. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a corrosion-resistant PE bottle structure with an exhaust assembly, which solves the problem that when storing corrosive liquids in traditional PE bottle structures, gases may be generated in the bottle due to volatilization or temperature changes of the liquid. If these gases cannot be discharged in time, not only may the pressure in the bottle increase, increasing the risk of bottle rupture, but may also affect the quality and stability of the liquid.

[0006] To achieve the above purpose, the utility model is implemented through the following technical solutions: a corrosion-resistant PE bottle structure with an exhaust assembly, including a PE bottle body, one side and the lower part of the PE bottle body are provided with an exhaust mechanism for exhausting the gas volatilized by the corrosive liquid inside the PE bottle body, and the exhaust mechanism includes:

[0008] A collecting assembly is arranged below the exhaust assembly and is used to collect the gas exhausted by the exhaust assembly;

[0009] The mounting assembly is arranged at the bottom of the collecting assembly and the PE bottle body, and is used to assemble and fix the collecting assembly and the PE bottle body.

[0015] Beneficial Effects

[0016] The utility model provides a corrosion-resistant PE bottle structure with an exhaust assembly. Compared with the prior art, it has the following beneficial effects:

[0017] (1) The corrosion-resistant PE bottle structure with exhaust assembly is designed with an exhaust mechanism. When the gas pressure inside the bottle reaches a certain level, the gas will push the sliding column to overcome the resistance of the compression spring and slide outward, thereby opening the exhaust groove and allowing the gas to be discharged. After the gas is discharged, the compression spring will push the sliding column to reset and close the exhaust groove. The gas discharged from the exhaust groove is collected by the collection assembly below. The gas enters the hollow column through the third connecting pipe and is finally collected in the collection cylinder. The design of the blocking piece and the first rotating rod allows the user to control the opening and closing of the hollow column by rotating the first rotating rod, thereby controlling the collection of gas.

[0018] (2) The corrosion-resistant PE bottle structure with exhaust assembly is designed with an installation assembly, which is responsible for assembling and fixing the collection assembly to the PE bottle body. By rotating the second rotating rod, the cross and the multiple groups of clamping rods thereon can be rotated, so as to cooperate with the clamping blocks at the bottom of the PE bottle body to achieve rapid fixation of the collection assembly to the PE bottle body and facilitate disassembly.

[0031] In this embodiment, the mounting assembly 33 includes a second rotating rod 331 rotatably mounted on the base plate 321, and a cross 332 is fixed to the upper end of the second rotating rod 331, and four rod ends of the cross 332 are integrally formed with a clamping rod 333, a groove is provided at the bottom of the PE bottle body 1, and a clamping block 334 is fixed inside the groove for the clamping rod 333 to cooperate with and plug into; by rotating the second rotating rod 331, the cross 332 and the multiple groups of clamping rods 333 thereon can be rotated, so as to cooperate with and plug into the clamping block 334 at the bottom of the PE bottle body 1, thereby realizing the rapid fixation of the collection assembly 32 and the PE bottle body 1.

[0033] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0034] During operation, when it is necessary to store corrosive liquid in the PE bottle 1, first unscrew the top cover 2, pour the liquid into the PE bottle 1 through the opening of the top cover 2, and then tighten the top cover 2 to close the top opening of the PE bottle 1.

By rotating the second rotating rod 331, the cross 332 and the multiple groups of clamping rods 333 thereon can be rotated, so as to cooperate with the clamping block 334 at the bottom of the PE bottle body 1 to achieve rapid fixation of the collection component 32 and the PE bottle body 1, and facilitate disassembly. Through the above working principle, the corrosion-resistant PE bottle structure with exhaust assembly can effectively store corrosive liquids, exhaust the volatile gases generated by them, and collect these gases to prevent gas leakage and environmental pollution.
