Embodiment Construction
[0011] The scheme of this application is further described in conjunction with the accompanying drawings as follows:
[0012] A double-layer thermal insulation sleeve cup, including an inner sleeve 1 and an outer sleeve 2 with an upward opening, the inner sleeve 1 is placed in the outer sleeve 2, and the openings of the two are closed along the connection to form Hollow interlayer chamber 3, the interlayer chamber 3 is filled with liquid with large specific heat capacity; the inner sleeve 1 is an excellent conductor of heat, and the outer sleeve 2 is a non-excellent conductor of heat.
[0013] The openings of the inner sleeve 1 and the outer sleeve 2 are connected and closed by an annular lip 4, which is also a poor conductor of heat.
[0014] The liquid with large specific heat capacity is pure water. The present invention first uses the structure of double sleeves to set up a partition between the water body and the outer wall of the cup to make the heat dissipation more gen...
