Description

Automatic closing cup cover based on energy storage

Technical Field

The invention relates to a cup cover of a water cup, in particular to an automatic closing cup cover based on energy storage.

Background

The existing container for containing liquid, such as a water cup, is composed of a cup body and a cup cover connected to the cup opening of the cup body. Functionally, the bowl cover mainly has two kinds: one is a traditional cup cover and the other is an automatic cup cover. The traditional cup cover needs to be unscrewed from the cup mouth when drinking water, which is troublesome, and the suction nozzle can be automatically ejected by only pressing a button on the cup cover without unscrewing the cup cover when the automatic cup cover drinks water. Drinking water through a suction nozzle arranged on the cup cover. For example, patent No. ZL201821274383.1 discloses a flip-type nozzle cup cover, which includes: lid 1,

top cap

2, 1 middle part of lid is equipped with delivery port 12, top cap 2 is installed in 1 upper end of lid through fixed pin 13, the bottom surface is provided with couple 14 under top cap 2, around having elasticity rubber band 15 on the couple 14, the elasticity rubber band 15 other end is walked around fixed pin 13 and is fixed inside lid 1, the bottom surface corresponds delivery port 12 position under top cap 2 and installs sealing plug 16, 1 one side of lid is equipped with according to keyway 17, 17 internally mounted has button 18 in the button groove, install reset spring 19 between button 18 and 17 medial surfaces in the button groove, button 18 upper portion is equipped with buckle 21, be equipped with the slot 20 that corresponds with buckle 21 on top cap 2.

Compared with the two modes, the two modes are more rapid and convenient, and are particularly suitable for children, old people and bedridden patients. However, in the nozzle cup with such a structure, the buckling structure of the buckle 21 and the groove 20 is often out of hook due to improper buckling or accidental touch of the button, which causes potential safety hazards such as water leakage and scalding.

Disclosure of Invention

The invention aims to provide an energy-storage-based automatic closing cup cover, which cannot be unhooked normally due to improper buckling or mistaken touch of a button, and avoids potential safety hazards of water leakage, people scalding and the like.

In order to achieve the purpose, the invention adopts the following technical scheme:

an automatic closing cup cover based on energy storage comprises a cover body connected to a cup opening of a cup body, wherein a frame body formed by a front side wall, a rear side wall, a left side wall and a right side wall is arranged on a top plate of the cover body, a sliding locking block is arranged on the bottom surface of the frame body, a first spring is arranged between the sliding locking block and the left side wall, support lugs are symmetrically arranged on the front side wall and the rear side wall, a first hinge hole of each support lug is hinged with first hinge shafts on the front side and the rear side of a rotating sleeve, torsion springs are arranged on support shafts on the front side and the rear side of the rotating sleeve, one end of each torsion spring is hooked on the support shafts, the other end of each torsion spring is pressed on the cover body, the lower end of each suction nozzle is connected with a liquid outlet of the top plate, the suction nozzle penetrates out of the middle part of the sliding locking block and is sleeved in the rotating sleeve at the upper part of the suction nozzle, the, the periphery of the frame body is provided with an upper cover connected with the cover body, the top of the upper cover is sunken downwards to form a channel for containing the suction nozzle, and two legs of the U-shaped button are slidably inserted into cover cavities on the front side and the rear side of the channel;

in the initial state, the torsion of the torsion spring bends and closes the suction nozzle through the rotating sleeve and is contained in the channel;

lifting the rotary shifting cover along the direction A, driving the rotary sleeve to rotate around the first hinge hole when the left end face of the rotary shifting cover abuts against the rotary sleeve, erecting the suction nozzle when the rotary shifting cover rotates to a preset limit position, and clamping the vertical hooks on the front side and the rear side of the sliding locking block in corresponding clamping grooves on the support shaft under the action of a spring to position the rotary sleeve; the U-shaped button is pressed leftwards, the U-shaped button overcomes the elasticity of the first spring to push the sliding locking block to move leftwards, the vertical hook is separated from the clamping groove, and the torsion of the torsion spring bends the suction nozzle to be closed in the channel through the rotating sleeve and restores to the initial state.

And a second spring is arranged between the end parts of two legs of the U-shaped button and the corresponding spring supporting seat of the upper cover.

Clamping protrusions are arranged on the front side and the rear side of the rotary shifting cover, and clamping holes matched with the clamping protrusions are formed in the front inner wall and the rear inner wall of the channel.

Backstop bosses are arranged on the outer sides of two legs of the U-shaped button, and backstop steps matched with the backstop bosses are arranged on the side wall of the cover cavity.

Compared with the prior art, the invention has the beneficial effects that: 1. the suction nozzle cannot be normally opened due to mistaken touch of the key, because the torsion of the torsion spring bends and closes the suction nozzle through the rotating sleeve, certain force is not applied, the torsion of the torsion spring cannot be overcome, and the suction nozzle cannot be opened; 2. the rotary poking cover is provided with double insurance, and is provided with a second anti-false-opening insurance besides the anti-false-opening insurance of the torsion spring, namely the rotary poking cover is pressed on the suction nozzle, and the clamping convex of the rotary poking cover is clamped in the clamping hole of the upper cover; 3. has the function of automatically closing the suction nozzle: the torsion spring with the stored energy can drive the rotary sleeve to bend and close the suction nozzle through the torsion force, and simultaneously drive the rotary shifting cover to be buckled in the clamping hole of the upper cover through the suction nozzle, so that the rotary shifting cover cannot be abnormally unhooked and opened due to improper buckling, potential safety hazards of water leakage, people scalding and the like are avoided, and the rotary shifting cover is particularly suitable for old people and children.
