Portable combined cup cover

Abstract

The invention discloses a portable combined cup cover which comprises an upper cover (2), a lower cover (9), a shed cap (7) and a spring (8). The upper cover (2) is fixedly connected with the lower cover (9) in a threaded matching manner, the lower cover (9) is provided with a sunken grid (14) integrally connected with the same, a shed rod (12)is arranged on a center hole of the sunken grid plate (14), the upper portion of the shed rod (12) is integrally connected with the shed cap (7), a thread nut (11) is fixed to the lower portion of the shed rod (12), a shed rod exhaust hole (13) is reserved at the center of the shed rod (12), a shed cap sealing ring (6) which is hermetically matched with the lower cover (9) is arranged on the periphery of the shed cap (7), and the spring (8) is arranged between the shed cap (7) and the sunken grid plate (14). The upper cover (2) is provided with an upper cover mandrel integrated with the same, the upper cover mandrel is provided with a rubber mandrel-sealing sleeve (3) which is hermetically matched with the shed rod exhaust hole (13). The portable combined cup cover has the advantages of simple and compact structure, convenience in opening, good sealing effect, convenience in detachment and cleaning, low production cost and the like.

Description

technical field [0001] The invention relates to a sealed cup cover of a vacuum insulation cup, in particular to a sealed combined cup cover that is easy to open, disassemble and wash. Background technique [0002] With the rapid development of the world economy, the standard of living and the quality of life have been significantly improved. The vacuum insulation cup has grown rapidly in recent years. my country has become the world's largest producer and consumer. The vacuum insulation cup has entered the common household common people's family. But existing vacuum insulation cup has the following deficiencies in daily life: the one, often can run into the situation that sealing cup lid can't be opened in use, trace it to its cause is that boiling water is poured into the cup and covers sealing cup lid Finally, as the temperature of the boiling water in the cup drops, the air in the cup will shrink, causing the air pressure in the cup to drop and be lower than atmospheric p...

Problems solved by technology

But existing vacuum insulation cup has the following deficiencies in daily life: the one, often can run into the situation that sealing cup lid can't be opened in use, trace it to its cause is that boiling water is poured into the cup and covers sealing cup lid Finally, as the temperature of the boiling water in the cup drops, the air in the cup will shrink, causing the air pressure in the cup to drop and be lower than atmospheric pressure to generate negative pressure. The lid is difficult to open or unscrew

The second is that the existing sealed cup lids cannot be disassembled after being assembled, which is inconvenient to clean, and there are sanitary corners, which cannot be cleaned at all. Or push-button switches to open and close or exhaust. These bounce-type or push-button switches will inevitably open naturally when they touch something else inadvertently during use, resulting in water leakage and other phenomena.

For this reason, many manufacturers and people of insight have carried out development and research, but so far there is no more reasonable way to solve the above problems
