Description
It is made up of two glass bottles inside and out. The two are
connected into one at the mouth of the bottle, the gap between the
two bottle walls is pumped into a vacuum to weaken thermal
convection, and the surface of the glass bottle wall is coated with
a bright silver film that reflects infrared thermal radiation. When
the bottle is high at high temperature, the thermal energy of the
contents does not radiate outward; when the bottle is low, the heat
energy outside the bottle does not radiate to the bottle, and the
thermos bottle effectively controls the three ways of heat
transfer: conduction, heat convection and radiation.
enclosure
Has a certain strength to protect the inner tank and increase the
decorative effect. The materials of the shell are tinned thin steel
plate, brass, alloy aluminum, stainless steel and plastic, etc.,
and there are black iron sheets, bamboo pipes, bamboo tubes, wood,
enamel and so on in China. For ease of use and aesthetics, the
shell can be used for a variety of shape changes and a variety of
decorations. Decorative methods include printing color, painting,
spray flowering, electroplating, spraying, polishing, engraving,
dyeing, etc.
Additional parts
Different components are equipped according to the outlet method.
Ordinary thermos bottles are suitable for holding shell handles,
pouring bottles and pouring water, and need to be equipped with
cork stoppers, soft rubber expansion stoppers, cavity roll ball
water control plastic stoppers, threaded sink rotary plastic
stoppers, etc. The thermos bottles that siphon out water need to be
equipped with siphon tubes and valve devices in the bottle bile.
The thermos bottle with air pressure outlet water is called the air
pressure thermos bottle, which has two structures. Commonly used is
to install a small air drum at the shell cover, press by hand or
through the mechanism, so that the liquid level is subjected to air
pressure, through the catheter out of the water; the other is that
a small electromagnetic vibration pump can be installed in the
shell, so that the liquid level is subjected to air pressure,
through the catheter out of the water. In order to meet the needs
of use, large-mouth thermos bottles containing food are also
equipped with non-toxic plastic linings and small set containers
with matching shapes.
