Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vacuum cups, and in particular to a vacuum cup lid and a vacuum cup. BACKGROUND

[0002] Vacuum cups have good hot water insulation effect, meeting the needs of users for drinking hot water in cold seasons, but hot water burns the mouth and is not drinkable, which is one of the biggest use pain points in the use of vacuum cups. The user of the vacuum cup often needs to open the cup cover and cool for a long time before drinking. After the user of the vacuum cup opens the cup cover, the hot water in the cup cannot be guaranteed not to spill during walking, riding or driving due to shaking or jolting. At present, there are vacuum cups with phase change materials filled in the double-layer vacuum cup shell interlayer on the market, which have the function of quickly cooling hot water, but the vacuum cups containing phase change materials have far lower insulation effect than ordinary vacuum cups, and cannot actively adjust the insulation performance. In addition, most of the vacuum cup covers on the market cannot be disassembled, so that the gap formed between the cup cover shell and the internal structure is difficult to clean, and a large amount of dirt accumulates after long-term use of the vacuum cup, which is unhygienic. CONTENT OF THE UTILITY MODEL

[0003] The embodiment of the present application provides a vacuum cup lid and a vacuum cup, which are used to solve the problem that the existing vacuum cup cannot actively adjust the insulation performance.

[0004] Therefore, according to one aspect of the present application, a vacuum cup lid is provided, which comprises a cup cover inner cylinder, a metal blocking sheet, a lifting cover, an elastic member and a pressing locking structure. The metal blocking sheet is arranged at the lower end of the cup cover inner cylinder and is used to block the lower end opening of the cup cover inner cylinder. An inner lining cylinder is arranged on the inner wall of the cup cover inner cylinder. The lifting cover is arranged in the inner lining cylinder in a sliding manner. The elastic member is arranged between the lower end of the lifting cover and the metal blocking sheet. The elastic member is used to provide the lifting cover with an elastic force to make the upper end of the lifting cover extend out of the inner lining cylinder. The side wall of the upper end of the lifting cover is provided with a heat dissipation through hole. The pressing locking structure is arranged between the outer side wall of the lifting cover and the inner wall of the inner lining cylinder. By pressing the lifting cover, the upper end of the lifting cover can be switched between extending out of the inner lining cylinder and retracting into the inner lining cylinder under the action of the pressing locking structure. When the upper end of the lifting cover extends out of the inner lining cylinder, the heat dissipation through hole is in communication with the outside air. When the upper end of the lifting cover retracts into the inner lining cylinder, the heat dissipation through hole is blocked by the inner lining cylinder.

[0005] According to another aspect of the present application, a vacuum cup is provided, which comprises a vacuum cup body and a vacuum cup lid as described above. The vacuum cup body is of a double-layer vacuum structure. The inner wall of the cup opening of the vacuum cup body is provided with an inner thread. The outer wall of the cup cover inner cylinder is provided with an outer thread matched with the inner thread.

[0006] The cup cover and the vacuum cup provided by the application have the advantages that, compared with the prior art, the cup cover of the application has two use modes, i.e. a heat preservation mode and a heat dissipation mode, by the cooperation of the cup cover inner cylinder, the metal blocking sheet, the lifting cover, the elastic member and the pressing locking structure, and the two modes can be switched by pressing. In the heat dissipation mode, the upper end of the lifting cover extends out of the inner lining cylinder, at this time, the metal blocking sheet and the outside air realize convective heat transfer through the heat dissipation through holes on the lifting cover, and the temperature of the hot water in the vacuum cup body is reduced through heat exchange of the metal blocking sheet. Since the lower end opening of the cup cover inner cylinder is blocked by the metal blocking sheet, the hot water in the vacuum cup body will not flow out in the heat dissipation mode. In the heat preservation mode, the upper end of the lifting cover is retracted into the inner lining cylinder, the heat dissipation through holes on the lifting cover are closed by the inner lining cylinder, and the heat dissipation capacity of the metal blocking sheet is reduced, so that the vacuum cup and the cup cover have a long-time hot water heat preservation function.

It can be understood that the magnetic locking prevents the lifting cover 3 from moving up and down freely after retracting into the inner liner 6. During the process of pressing down the lifting cover 3 again, the jump gear 53 moves down and rotates to unlock. Under the action of the elastic element 4, the jump gear 53 pushes the lifting cover 3 up and causes the upper end of the lifting cover 3 to extend out of the inner liner 6.

Multiple wedge-shaped parts are spaced around the circumference on the side of the lower end of the lifting cover 3. The bottom end of each wedge-shaped part extends to both sides to form two wedge-shaped surfaces. The number of locking blocks is the same as that of the wedge-shaped parts, and they are also spaced around the side of the jump gear 53.
