Description

Technical Field

[0001] The utility model relates to a cup cover which can be opened and closed by rotation, and belongs to the technical field of thermos cups. Background Art

[0002] Cups are essential items in people's daily lives. Cups can be divided into many types according to their uses, such as water cups, coffee cups, hot drink cups, thermos cups, etc. Take thermos cups as an example. Thermos cups are generally made of ceramic, stainless steel or titanium alloy, and are containers with a vacuum layer on the cup body. There is a sealing cover on the top. The vacuum layer can insulate the water or other liquids in the container from the outside world to achieve the purpose of heat preservation or cold preservation. The internal structure of a thermos cup usually has many layers. The vacuum layer is used to prevent heat conduction. The outer wall of the vacuum layer is plated with silver to prevent heat radiation. A thermos cup usually includes a cup liner, an outer shell and a cup lid.

[0003] In the prior art, the cup cover is usually opened by fixing the cup cover on the cup body through a threaded connection, which has a simple structure and reliable connection. However, this threaded connection requires the user to cooperate with both hands to take off the cup cover, which is very inconvenient in some occasions. In addition, the user needs to tighten or loosen the cup cover one circle at a time before and after each use to fix and take off the cup cover, and the closing and opening efficiency is very low.

[0004] At present, there is a push-type cup cover (CN 206062786 U), which includes a push part, a sliding part connected to the push part through a conical surface so that the sliding part can move away from the push part when the push part moves downward, and an elastic band acting on the sliding part. The elastic band acts on the two sliding parts so that the two sliding parts have a tendency to approach each other, and a hook part is arranged on the side of the sliding part close to the push part; when in use, the sliding part is pressed to slide, and the hook part of the sliding part moves away from the cup body, so that the cup cover can be removed as a whole, and then water can be drunk or poured into the cup through the cup mouth. The difference between the utility model and the above-mentioned patent document is that the elastic band of the above-mentioned patent document will be stretched after being stretched for a long time. The assembly is difficult, and the sliding part must be placed first and then the elastic band is put on. During this installation process, the sliding part will be tilted, and the button will also be tilted when installed. There is also an outer cover to be pressed, which is not easy to assemble. There is no positioning point when the sliding part is pushed open, and there is no positioning point when the sliding part is reset. Utility Model Content

The direction of the upper contact is the same as that of the second magnet. A hole is provided on the first mounting plate to facilitate the installation of the contact mounting plate and to limit the knob assembly.

[0016] The second mounting plate is installed with an exhaust valve, the upper end of the exhaust valve passes through the first mounting plate and is connected to a lower contact that cooperates with the upper contact to achieve exhaust, the lower end of the exhaust valve passes through the second mounting plate and is fixed by bolts, and a second spring is sleeved on the outside of the exhaust valve to achieve resetting of the exhaust valve.

[0017] The cup body is provided with a cup mouth assembly, which includes a concave cup mouth and a convex cup mouth from bottom to top, the concave cup mouth matches the hook, and the upper cup cover and the lower cup cover are provided with a direct drinking mouth. The separation and connection of the concave cup mouth and the hook realize the opening and closing of the cup cover and the cup body.

[0018] The utility model has the following characteristics and significant effects:

[0019] The utility model relates to a cup cover that can be opened and closed by rotation. When a user rotates a knob assembly to a separation position, a first magnet and a second magnet repel each other with the same polarity, thereby pushing a locking assembly outward, separating a hook from a recessed cup mouth, and separating the cup cover from the cup body. Then, the knob assembly is rotated to a locking position, and a first spring returns to push the locking assembly inward, thereby locking the cup cover and the cup body. When the knob assembly is rotated, an upper contact presses down a lower contact to drive the exhaust valve to move downward, thereby exhausting the air. BRIEF DESCRIPTION OF THE DRAWINGS
