Description

Technical Field

[0001] The invention relates to a cup cover for a water cup, in particular to an energy storage type automatic closing cup cover. Background Art

[0002] Existing containers for holding liquids, such as water cups, are composed of a cup body and a cup cover connected to the mouth of the cup body. In terms of function, there are two main types of cup covers: one is a traditional cup cover and the other is an automatic cup cover. The traditional cup cover needs to be unscrewed from the mouth of the cup when drinking water, which is troublesome. The automatic cup cover does not need to be unscrewed when drinking water. You only need to press the button on the cup cover and the suction nozzle will pop out automatically. Drink water through the suction nozzle set on the cup cover. For example, the patent number ZL201821274383.1 discloses a flip-top cup cover with a nozzle, which includes a cover body 1 and a top cover 2. The cover body 1 is provided with a water outlet 12 in the middle, the top cover 2 is installed on the upper end of the cover body 1 through a fixing pin 13, a hook 14 is provided on the lower bottom surface of the top cover 2, an elastic rubber band 15 is wound around the hook 14, and the other end of the elastic rubber band 15 is fixed inside the cover body 1 by passing through the fixing pin 13, a sealing plug 16 is installed on the lower bottom surface of the top cover 2 at a position corresponding to the water outlet 12, a button groove 17 is provided on one side of the cover body 1, a button 18 is installed inside the button groove 17, a reset spring 19 is installed between the button 18 and the inner side of the button groove 17, a buckle 21 is provided on the upper part of the button 18, and a groove 20 corresponding to the buckle 21 is provided on the top cover 2.

[0003] Compared with the two methods, the latter is faster and more convenient, and is especially suitable for children, the elderly and bedridden patients. However, the buckle 21 and the groove 20 of the suction cup with this structure often fail to buckle properly or accidentally touch the button instead of being unhooked normally, causing safety hazards such as water leakage and scalding. Summary of the invention

[0004] The purpose of the present invention is to provide an energy storage type automatic closing cup lid, which will not be unhooked normally due to inadequate buckling or accidental button touching, thereby preventing unsafe hidden dangers such as water leakage and scalding.

[0005] To achieve the above object, the present invention adopts the following technical solution:

[0011] Compared with the prior art, the present invention has the following beneficial effects: it will not open abnormally due to accidental button touching, because the spring 1 bends and closes the nozzle through the meshing rack gear, and if a certain force is not applied, the elastic force of the spring 1 cannot be overcome, and the nozzle cannot be opened. When the nozzle needs to be closed, the rotating cover lifted when drinking water is released, and the spring 1 with stored energy can drive the rotating sleeve to bend and close the nozzle through the meshing rack gear, and it will not open abnormally due to unhooking due to inadequate buckling, eliminating the hidden dangers of water leakage, scalding, etc., and is particularly suitable for use by the elderly and children.

[0012] A further beneficial effect is that it has double insurance, in addition to the spring one which is an anti-mistaken opening insurance, it also has a second anti-mistaken opening insurance, that is, the rotary cover is pressed on the suction nozzle, and the convex snap of the rotary cover is snapped into the snap hole of the upper cover; it is more convenient to use: in the process of opening the suction nozzle, the spring one stores energy, and the hooks on the outer sides of the right ends of the two racks are snapped onto the right end surfaces of the front and rear side walls under the action of the elastic force of the racks themselves to prevent the rack slider from moving left. At the same time, the inner push block of the U-shaped button 8 prevents the rack slider from moving right. At this time, the suction nozzle can be sucked to drink water without having to lift the rotary cover with hands. When the suction nozzle needs to be closed, the U-shaped button is pressed to the left, and the spring one with energy stored can drive the rotating sleeve to bend and close the suction nozzle through the meshing rack gear, and at the same time drive the rotary cover to snap into the snap hole of the upper cover through the suction nozzle.
