In our daily life, the insulated water bottle is a seemingly ordinary but magical existence. With its unique functions, it brings great convenience to our lives, allowing warmth and coolness to continue over the long river of time.
The insulated water bottle can keep the heat mainly due to the structure of the bottle. Through careful observation, we can found that the bottle is composed of two thin glass shells, with a vacuum between the two shells, and a thin layer of silver is plated on the inside of the bottle. It is this structure that allows the insulated water bottle to keep the heat or cold continuously.
The Principle of Insulated Water Bottle
After boiling water is poured into the insulated water bottle, due to its unique design structure, the heat of the water cannot be exchanged with the outside world in the usual way.
Three Ways of Heat Transfer are Cut Off
Erste, we need to cut off the convection of heat. For the theraml coffee carafe, because the bottleneck is thin and tightly plugged by the cork, the only channel for heat convection is cut off. Similarly, the insulated water bottle is also blocked by the lid and rubber ring, and cannot generate heat convection with the outside world.
Second, it blocks heat conduction. Metal has a good heat conduction effect. If the water inside is isolated from the outside world only through the stainless steel body of the insulated water bottle, it will not have the effect of heat preservation at all.
In the absence of a medium, heat conduction cannot occur. Therefore, the insualted water bottle manufacturer designs the insulated water bottle with two layers of glass shells, and then removes the air between the two layers to form a vacuum. The medium for heat conduction – air becomes very thin, and the heat conduction channel is also blocked.
Dritte, it is necessary to prevent heat radiation from taking away heat. In daily life, the sunlight we see is a kind of thermal radiation, and it is the thermal radiation of sunlight that makes us feel warmer. Thermal radiation is a way of transferring heat. The higher the temperature of an object, the stronger the thermal radiation it releases.
Since the water we usually put in a insualted water bottle or thermal coffee carafe has a high temperature, insulated water bottle & vacuum flask manufacturers use silver plating to reflect thermal radiation heat and reduce heat loss.
In addition, the sealing design of the insulated water bottle is also a key factor in ensuring the heat preservation effect. The carefully designed sealing silicone ring and press-type lid can fit tightly to prevent air from entering and heat from escaping.
Why does a Insulated Water Bottles Stop Working?
Insualted water bottle may not keep warm during use. The reasons may be as follows:
1.insulated water bottle has poor sealing performance. Please check if there are gaps in the lid or other parts of the insulated water bottle, which may cause heat loss. If the lid does not have a sealing ring, the insulation performance may also be reduced.
2.The welding seams of the insulated water bottle material itself are corroded. Some stainless steel insulated water bottle have defects in the process, and uneven welding gaps may appear in the liner, which accelerates the heat transfer between the two layers of the cup wall and causes heat loss faster.
3.The insulated water bottle is hit, causing the shell and the vacuum layer to break, and air enters the interlayer, affecting the insulation performance. In this case, the water temperature in the insulated water bottle will drop faster.
In real life, insulated water bottle have a wide range of uses. For office workers, they can provide them with warmth and refreshing energy at any time during their busy work. For housewives, insulated water bottle can allow their families to drink warm soup at any time, adding warmth to family life. For outdoor sports enthusiasts, whether hiking in cold mountains or cycling in hot deserts, insulated water bottle can ensure that they are hydrated at any time.
Choosing the Right Insulated Water Bottle
The material of the inner liner of the insulated also plays a vital role. Common ones include stainless steel, glass und ceramic. High-grade stainless steel can ensure that the liquid in the kettle is not contaminated while maintaining a stable temperature. However, when purchasing, you must choose a food-grade stainless steel liner, such as 304 or 316. Non-compliant stainless steel liners may cause excessive heavy metals and affect health. The glass liner is pure and non-toxic and does not affect the taste of water. The disadvantage is that it is not resistant to falling and is not easy to carry with you.
Beautiful and Practical
In addition to the heat preservation function, modern insulated water bottle are also increasingly focusing on humanization and aesthetics in design. When choosing an insulated water bottle or vacuum flask, we should pay attention to some details, which often reflect the professional ability of manufacturers and designers. A good insulated water bottle or vacuum flask should have the following characteristics:
Sealing: Good sealing performance to ensure that the liquid will not leak, and easy to open and close, suitable for placing in a backpack or handbag.
Ergonomic handle: The handle design should be comfortable and easy to hold, especially when the bottle is full of liquid, the handle design can greatly improve the comfort of carrying and using.
Lightweight: Use lightweight materials for easy carrying and moving.
Impact resistance: The bottle body should be able to withstand a certain degree of impact and extrusion, and is not easy to deform or break.
Anti-slip base: The anti-slip base can increase stability and avoid accidental tipping.
Material safety: Use non-toxic, odorless, and corrosion-resistant materials, such as food-grade stainless steel or high-quality plastic.
Appearance design: Fashionable or classic design and rich color selection, you can choose according to your personal preferences, so as to balance practicality and aesthetics.
As an insulated water bottle and vacuum flask manufacturer that provides both OEM and ODM customization services, in China, Moya has the best design capabilities in the industry. We incorporate the above features into each of our products. In terms of balancing practicality and beauty, each of our products is extreme and unique.
