An opening/closing mechanism of a vacuum flask lid

Abstract

The invention provides an opening / closing mechanism of a vacuum flask lid. The opening / closing mechanism enables boiled water remaining in a flask nozzle and a water outlet channel to flow back to an inner container of a flask body, so that the brewing and taste of beverages can be guaranteed when water is added next time. The opening / closing mechanism comprises a button, a first connecting rod, a second connecting rod, a first pressing rod, a second pressing rod and a rubber plug, wherein the button is connected with a push block; the push block is pressed against the lower portion of the outer end of the first connecting rod; the inner end of the first connecting rod is in hinge joint with the upper end of the first pressing rod; the lower end of the first pressing rod is in hinge joint with the outer end of the second connecting rod; the inner end of the second connecting rod is in hinge joint with the upper end of the second pressing rod; the rubber plug is fixed to the lower end of the second pressing rod; the second connecting rod is provided with a load bearing block; the first connecting rod and the second connecting rod are supported on a lid body via rotating shafts; the second connecting rod is located on the lower side of the first connecting rod. The opening / closing mechanism is characterized in that the side wall of the water outlet channel of the flask lid is provided with a buffer device which is pressed against the inner end of the second connecting rod.

Description

technical field [0001] The invention relates to a pot lid of a kettle, in particular to an opening and closing structure of the kettle lid. Background technique [0002] Kettle usually consists of a pot lid, a kettle body and a spout. Existing pot lids such as figure 1 As shown, the pot cover 1 is provided with a water outlet channel 12 communicating with the inner tank of the kettle body and the spout, and an opening and closing mechanism for opening and closing the water outlet channel 12. Water outlet 11, its lower end is provided with the water inlet 13 that communicates with kettle body liner, and opening and closing mechanism comprises button 10, the first connecting rod 7, the second connecting rod 4, the first depression rod 6, the second depression rod 2 and Rubber plug 14, the button 10 is connected to the shifting block 9, the shifting block 9 abuts against the lower part of the outer end of the first connecting rod 7, the inner end of the first connecting rod 7 ...

AI Technical Summary

Problems solved by technology

In the process of pouring water, the body of the pot is tilted downward, and the button 10 is pressed downward. Under the action of the opening and closing mechanism, the rubber plug 14 is lifted up, and the water inlet 13 is opened, so that the boiling water in the inner pot of the pot body flows out, and the cup After the water in the cup is full, release the button 10, and the water inlet 13 is closed. At the moment when the button 10 is released, the body of the pot is still tilted, so that some boiling water will remain in the spout and the water outlet channel 12, but the rubber plug 14 At the moment when the button 10 is released, the water inlet 13 is immediately blocked under the action of the weight block 3, which will cause the remaining boiled water in the spout and the water outlet channel 12 to be unable to return to the inner tank of the kettle body, and will gradually Cooling, and when adding water next time, this part of the cooled boiled water will first enter the water cup, which will reduce the water temperature and affect the brewing and taste of the drink
