Vacuum cup capable of preventing tea leaves from adhering to walls

Abstract

The invention discloses a vacuum cup capable of preventing tea leaves from adhering to the wall, and relates to the technical field of vacuum cups, the vacuum cup comprises a cup body and a cup cover,longitudinal sliding grooves are formed in the inner wall of the cup body, a metal mesh plate is slidably connected between the inner walls of the longitudinal sliding grooves, and a side plate is fixedly connected to the top of the metal mesh plate; a metal strip is rotationally connected between the two sides of the side plate, a threaded column is fixedly connected to the bottom of the metal net plate, the outer side of the threaded column is sleeved with a torsion spring, the top of the torsion spring is fixedly connected with the metal net plate, and a containing device is fixedly connected to the bottom of the torsion spring. According to the vacuum cup capable of preventing the tea leaves from adhering to the wall, a multi-layer heat preservation structure can be adopted, the heatpreservation effect of the vacuum cup is improved, meanwhile, the operation is simple when the vacuum cup is opened, the cup cover can be conveniently opened for drinking water, the tea leaves in thevacuum cup can be poured out without forcibly throwing, and the occupied space is small when the tea leaves are poured out; and people nearby are not easily touched by mistake when the tea leaves arepoured out.

Description

technical field [0001] The invention relates to the technical field of thermos cups, in particular to a thermos cup capable of preventing tea leaves from sticking to the wall. Background technique [0002] The thermos cup is generally a water container made of ceramics or stainless steel with a vacuum layer. It has a cover on the top and is tightly sealed. The vacuum insulation layer can delay the heat dissipation of the water and other liquids inside to achieve the purpose of heat preservation. [0003] Thermos cups are most likely to dissipate heat from the joint of the cup mouth. Existing thermos cups usually only use a single-layer lid for heat preservation, which has insufficient heat preservation effect. The double-layer structure in the cup lid is used to keep heat and drink water. The operation is complicated and the lid cannot be opened quickly. It is convenient to drink water. When the tea leaves in the teacup are poured out, they need to be thrown out forcefully, ...

[0003] Thermos cups are most likely to dissipate heat from the joint of the cup mouth. Existing thermos cups usually only use a single-layer lid for heat preservation, which has insufficient heat preservation effect. The double-layer structure in the cup lid is used to keep heat and drink water. The operation is complicated and the lid cannot be opened quickly. It is convenient to drink water. The tea leaves in the teacup need to be thrown out forcefully when pouring out, which requires a large space, and it is easy to hit nearby people when pouring tea leaves and cause damage
