Description

Technical Field

[0001] This utility model relates to the field of thermos bottles, and more particularly to an antibacterial thermos bottle that is easy to clean. Background Technology

[0002] A thermos flask is a container used to maintain a relatively stable temperature of an object. An antibacterial thermos flask is a container that adds antibacterial function to a regular thermos flask. The common method is to add antibacterial agents, which often contain metal ions such as silver, copper, and zinc, or some organic compounds with antibacterial properties. Taking silver ions as an example, when they come into contact with bacteria, they can destroy the bacterial cell membrane, cause the proteins and other substances inside the bacteria to coagulate, and also interfere with the bacterial respiratory enzyme system, hindering their metabolism, thereby inhibiting bacterial growth and reproduction.

[0003] Various substances can easily remain inside existing thermos flasks. If they are not cleaned in time, these residues will ferment and deteriorate over time, producing an unpleasant odor. This odor not only affects the taste of the beverage but may also indicate the presence of harmful microorganisms or chemicals inside the flask, which is detrimental to health. These substances provide nutrients and a living environment for bacteria, thereby weakening their antibacterial function and leading to a large-scale bacterial growth, ultimately affecting the hygiene and safety of the beverage.

[0004] Therefore, given that existing thermos bottles are prone to leaving various residues inside, and if they are not cleaned in a timely manner, harmful microorganisms or chemicals may exist inside. These substances can lead to the proliferation of bacteria, ultimately affecting the hygiene and safety of beverages. Therefore, an easy-to-clean antibacterial thermos bottle can be designed, featuring a detachable design for easy cleaning, thereby improving the safety of using the antibacterial thermos bottle. Utility Model Content

[0005] To address the problem that existing thermos flasks are prone to leaving various residues inside, and that if they are not cleaned in a timely manner, harmful microorganisms or chemicals may exist inside, which can lead to the proliferation of bacteria and ultimately affect the hygiene and safety of beverages.

[0006] The technical solution of this utility model is as follows: an easy-to-clean antibacterial thermos bottle, including an outer shell, a double-layer stainless steel antibacterial inner liner and a sealing ring; the inner side of the outer shell is provided with a double-layer stainless steel antibacterial inner liner for holding liquid, the upper part of the outer shell is provided with a sealing ring, the lower part of the outer shell is provided with a connecting round shell, the upper edge of the connecting round shell is provided with an annular snap-fit ​​groove, and the lower edge of the outer shell is fixedly installed with an annular snap-fit ​​plate corresponding to the annular snap-fit ​​groove.

[0007] Furthermore, a circular slot is provided in the middle of the upper part of the connecting shell for placing a double-layer stainless steel antibacterial inner liner. The annular snap-fit ​​plate drives the outer shell to be positioned and snapped into the connecting shell along the annular snap-fit ​​slot.

[0008] Furthermore, multiple sets of fixing pins are provided around the outside of the connecting round shell, and the fixing pins pass through the connecting round shell and the annular snap-fit ​​plate.

[0009] Furthermore, a round cover is provided on the top of the double-layered stainless steel antibacterial inner liner, and a rubber stopper is fixedly installed at the bottom of the round cover.

[0010] Furthermore, the rubber stopper causes the round cap to adhere and connect with the inner wall of the double-layered stainless steel antibacterial inner liner.

[0011] Furthermore, a first annular connecting groove is formed between the outer shell and the double-layer stainless steel antibacterial inner liner, and a second annular connecting groove is formed between the double-layer stainless steel antibacterial inner liner. A first rubber ring is fixedly installed at the lower edge of the sealing ring, and a second rubber ring is fixedly connected to the sealing ring inside the first rubber ring.

[0012] Furthermore, the sealing ring is positioned and connected to the outer shell and the double-layer stainless steel antibacterial inner liner via the first rubber ring and the second rubber ring along the first annular connecting groove and the second annular connecting groove.

[0013] The beneficial effects of this invention are as follows: After long-term use, the unique detachable structure design allows users to easily remove the rubber stopper on the double-layered stainless steel antibacterial inner liner. A simple operation allows for the detailed disassembly of the circular shell and outer shell connected to the inner liner, fully exposing the double-layered stainless steel antibacterial inner liner. This significantly reduces cleaning difficulty and greatly facilitates comprehensive cleaning of all internal parts. Simultaneous cleaning of the inner shell is also easier, reducing cleaning dead spots. Furthermore, the detachable design greatly shortens the time required for cleaning the thermos, allowing users to complete the cleaning without expending excessive effort or time. This effectively improves the daily maintenance efficiency of the thermos, enabling more frequent use and ensuring it remains in good working order. The detachable design ensures that every corner inside the thermos can be thoroughly cleaned, effectively preventing dirt and bacteria residue. The antibacterial properties of the double-layered stainless steel antibacterial inner liner further inhibit bacterial growth, providing users with a safer and healthier drinking environment and greatly reducing the potential health threats posed by using unclean thermoses.
