Description

thermos cup

technical field

The invention relates to a thermal insulation appliance which is not easy to conduct heat transfer, in particular to a thermal insulation cup. the

Background technique

At present, the thermal insulation time of thermos cups on the market is not long enough, generally only 3 to 5 hours. There has never been a thermos cup with two layers of inner and outer shells and an inner liner in the middle, and the inner liner is a vacuum thermos cup. The heat preservation cup body with two layers of inner shell and inner tank and inner tank vacuum can greatly improve the effect of blocking heat transfer and solve the technical problem that the heat preservation time of existing products is not long enough. the

Utility model content

The purpose of the utility model is to overcome the deficiencies in the prior art and provide a thermos cup which is easy to process and manufacture, has a simple structure and has a long heat preservation time. the

The purpose of this utility model is achieved through the following technical solutions. the

The utility model comprises a cup body and a cup cover. The cup body includes an inner shell and an outer shell, and an inner tank is arranged between the inner shell and the outer shell, and the inner tank is vacuum. the

The cup cover can be provided with a round hole for the straw to enter and a movable cover layer. The movable cover layer can rotate relative to the cup cover body. When the lid body is rotated until the round hole on the movable cover layer corresponds to the round hole on the cup lid, the straw can be inserted and used. When staggered, the lid seals to keep warm. The cup cover can be provided with a cup spout and a cup spout cover, which are used to replace the round hole and movable cover layer provided by the cup cover for the straw to enter. the

For heat preservation and compact structure, the inner shell of the utility model is welded with food-grade PP and the outer shell. the

In order to better block heat transfer and improve the effect of heat preservation, the inner container of the utility model is a glass inner container, and the outer layer of the glass inner container is electroplated. the

In order to enhance the sealing effect, prevent water leakage and better heat preservation, the joint of the cup cover and the cup body of the utility model is provided with a cup cover sealing ring, which can be made of silica gel; For firmness and shockproof, the inner pad can be in the shape of a ring around the inner tank, or it can be a support shape from the bottom of the inner tank; a plastic ring is provided at the junction of the inner shell and the inner tank, which is used for shockproof, fastening and sealing. The plastic ring can be made of rubber. the

The idea of this utility model is that the insulation body has a three-layer structure, that is, the outer shell and the inner shell, and an inner tank is arranged between the outer shell and the inner shell, and the inner tank is a vacuum. The thermos cups belonging to the above thermal insulation body structure all belong to the protection scope of the present utility model. . the

Adopt above-mentioned technical scheme, the utility model has following beneficial effect:

1. The structure of the inner and outer shells of the cup and the inner tank in the middle increases the level of heat transfer, and the vacuum insulation layer of the inner tank increases the difficulty of heat transfer, so the heat preservation time of the utility model is much longer than that of ordinary thermos cups , reaching more than 10 hours;

2. The structure is simple, easy to manufacture, not hot to use, and easy to carry. the
