Abstract

The invention relates to a thermal insulation kettle sealing ring and a thermal insulation kettle. The thermal insulation kettle sealing ring comprises an annular sealing part and an annular fixing part, wherein the fixing part is provided with a clamping structure for being connected with a kettle lid assembly of the thermal insulation kettle; the sealing part is arranged below the fixing part and comprises a first convex edge extending inwardly and a second convex edge extending outwardly in the circumference, the lower side of the first convex edge is provided with a first sealing surface, the lower side of the second convex edge is provided with a second sealing surface, and the second sealing surface extends obliquely towards the radial outer side from bottom to top; and an annular bulge is arranged on the first sealing surface, and at least one exhaust port is arranged on the annular bulge. As the thermal insulation kettle sealing ring is provided with the first sealing surface and the second sealing surface at the same time, sealing can be carried out on both a joint between a liner opening and the kettle lid assembly and the upper surface of a sliding sealing lid; and as the exhaust port is arranged on the annular bulge, the problems that steam or hot water sprays outwardly instantly when a water outlet switch is switched on.

Description

technical field

[0001] The invention relates to heat preservation container technology, and more specifically relates to a heat preservation pot sealing ring and a heat preservation pot. Background technique

[0002] Thermal jugs are widely used to keep liquids, especially hot water, warm. The thermos pot generally includes a pot body, a pot lid assembly and a handle, wherein the pot lid assembly is provided with a water outlet channel, a water outlet switch, and a sliding sealing cover for sealing the water outlet channel. A sealing ring is provided on the outer periphery and at the mouth of the water outlet channel to respectively seal the outer periphery of the lid assembly of the thermos pot and the water outlet channel. Deformation and looseness will affect the thermal insulation performance. When the water outlet switch is pressed to pour water at the same time, the spout is prone to problems such as spraying hot water steam or spraying water. Contents of the invent...
