Description

Technical Field

[0001] This utility model relates to the field of water cup technology, specifically to a water cup lid with a safety lock that opens instantly. Background Technology

[0002] A thermos flask is generally a container for holding tea or water, made of ceramic or stainless steel with a vacuum layer. It has a lid that seals tightly, and the vacuum insulation layer slows down the heat dissipation of the liquid inside, thus keeping it warm. It is portable and keeps drinks warm, making it popular with consumers. Currently, most thermos flasks on the market have threaded lids, requiring one hand to hold the flask while the other hand rotates the lid to open.

[0003] With the development of the times and the continuous improvement of people's health awareness, more and more people will go to indoor or outdoor cycling, running and other sports in their spare time. During the exercise, people need to drink water to replenish the water in their bodies. The water bottles carried during exercise are called sports bottles. The sports bottles on the market usually have screw-on caps, which are inconvenient to operate, or they can be drunk directly from the spout, which is easily contaminated by the environment and is very unhygienic.

[0004] Sports water bottles, as the name suggests, are water containers carried during outdoor sports. Compared to other water containers, sports water bottles are characterized by their durability, safety, reliability, and convenient safety features. Bottles are commonly used packaging containers in daily production and life. Most bottle caps are connected to the bottle body by threads, requiring the cap to be loosened before each opening. When this needs to be repeated multiple times, this operation is very cumbersome and affects efficiency. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a water bottle lid with a safety lock that opens instantly. It features a compact structure, ease of use, and excellent sealing. It solves the problem of easily opening and closing sports bottles. Through a mechanical linkage structure, it achieves a safe operating procedure of "venting air first, then opening the lid," effectively preventing liquid splashing caused by pressure differences when opening hot drinks.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0007] A water cup lid with a safety lock that opens instantly includes a lid, a lid seat inside the lid, an exhaust rod that is movably inserted into the lower part of the lid seat, button holes on both sides of the lid, an exhaust button and a switch button respectively inserted into the button holes, locking blocks on both sides of the upper part of the lid seat, and a push block between the switch button and the locking blocks to drive the locking blocks to move and open.

[0026] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0027] Example: Figure 1-4 As shown, a water cup lid with a safety lock that opens instantly includes a lid 3, with a handle ring 2 integrated into the upper end of the lid 3. A lid seat 6 is located inside the lid 3, and a pressure cap 14 is provided between the upper end of the lid seat 6 and the lid 3, engaging with the lid seat 6. An exhaust rod 13 is provided at the lower part of the lid seat 6, movably connected to it, and a silicone sealing ring 12 is provided between the exhaust rod 13 and the lid seat 6. Button holes 7 are provided on both sides of the lid 3, with an exhaust button 1 and a switch button 4 respectively inserted into the button holes 7. Locking blocks 5 are provided on both sides of the upper part of the lid seat 6, and a push block 8 is provided between the switch button 4 and the locking blocks 5 to drive the locking blocks 5 to move and open. An exhaust connecting rod 9 is provided between the exhaust button 1 and the exhaust rod 13, and limiting ribs 15 are provided on both sides of the exhaust connecting rod 9, engaging with and guiding the locking blocks 5. The lower part of the exhaust connecting rod 9 is provided with a spring sleeve 10 that is inserted into the exhaust connecting rod 9 and the exhaust rod 13. A spring 11 that is sleeved with the exhaust rod 13 is provided between the spring sleeve 10 and the cup lid seat 6.

[0028] Working principle:

[0029] Step 1: Press the exhaust button (preparation stage).

[0030] The user presses the exhaust button 1.

[0031] The force is transmitted downwards through the exhaust connecting rod 9.

[0032] The exhaust connecting rod 9 drives the lower spring sleeve 10 and exhaust rod 13 to overcome the elastic force of the spring 11 and move downward together.

[0033] The vent rod 13 moves downwards, and the sealing head at its bottom moves away from the outlet, creating a tiny gap inside the cup lid. At this time, the high-pressure steam or air inside the cup is released through this gap, balancing the air pressure inside and outside the cup. The "venting" function is complete.

[0034] Step 2: Press the switch button (unlocking and opening the lid).

[0035] After exhausting the air, the user presses switch button 4.

[0036] Pushing the pusher block 8 with force will in turn push the locking block 5.

[0037] Lock block 5 moves inward from the "locked" position to the "unlocked" position, no longer blocking the cup body.

[0038] At this point, the cup lid is unlocked, and the user can lift the lid directly from the unlocked state to open it instantly.

[0039] Step 3: Release the button (reset phase).

[0040] The user releases both hands.

[0041] Spring 11 returns to its original deformation, generating an upward thrust.

[0042] The elastic force acts on the exhaust rod 13 and the exhaust connecting rod 9 through the spring sleeve 10, causing them to return to their original position.

[0043] The exhaust rod 13 re-blocks the outlet, restoring the seal.

[0044] The exhaust button 1 then pops up.

[0045] The switch button 4 and the locking block 5 are usually also designed with independent return springs to return them to their initial locked positions.

[0046] The venting mechanism consists of a venting button 1, a venting connecting rod 9, a spring sleeve 10, a spring 11, a venting rod 13, and a silicone sealing ring 12. This mechanism runs through the center of the cup lid seat 6. Pressing the venting button 1 alone moves the venting connecting rod 9 downwards, pressing the venting rod 13 to release air, without opening the lid. After pressing the venting button 1, pressing the switch button 4 causes the venting connecting rod 9 to move downwards, disengaging the limiting rib 15 from the locking block 5. Under the pressure of the switch button 4, the two locking blocks 5 move towards the center, opening the lid.

[0047] The protrusions on both sides of the lower part of the exhaust connecting rod 9 limit the movement of the two locking blocks 5. When the exhaust connecting rod 9 is not in motion, it holds the locking blocks 5 in a locked state. When the exhaust button 1 is pressed, the exhaust connecting rod 9 moves downward, and the protrusions on both sides of the lower part of the exhaust connecting rod 9 separate from the locking blocks 5. At this time, the lock blocks 5 are slid inward by the switch button 4 to achieve the instant opening function.

[0048] In summary, this instant-opening water bottle lid with a safety lock features a compact structure, ease of use, and excellent sealing. It solves the problem of easily opening and closing sports bottles. Through a mechanical linkage structure, it achieves a safe operating procedure of "venting air first, then opening the lid," effectively preventing liquid splashing caused by the pressure difference between the inside and outside when opening hot drinks.
