WATER BOTTLE

Description

TECHNICAL FIELD

The present disclosure relates to a field of water bottles, and in particular to a water bottle.

BACKGROUND

Generally speaking, a water bottle is a container configured to hold liquids and is a common everyday item. The water bottle commonly comprises a bottle body configured to hold water and a lid configured to seal an opening of the bottle body. The lid has a water outlet. The water outlet may be designed as a drinking spout for direct drinking water, or the water outlet may be designed as a straw inserting into the bottle body for drinking. The lid is typically equipped with a flipping cap configured to seal the water outlet, and a user is allowed to flip the flipping cap to drink water. However, conventional water bottles may be opened by unscrewing the bottle body when the lid is tightly closed, which causes water leakage. When the water in the bottle is very hot, the water leakage may cause burns to the user. Furthermore, even in some other water bottles, the lid is only allowed to be separated from the bottle body when the flipping cap is opened, the flipping cap is easily locked without contact, resulting in poor user experience.

SUMMARY

The present disclosure is to solve a technical problem in the prior art that conventional water bottles may be opened by unscrewing a bottle body thereof when a lid thereof is tightly closed, which causes water leakage and causes burns to the user when the water in the bottle is very hot. The present disclosure is further to solve a technical problem in the prior art that even in some other water bottles, the lid thereof is only allowed to be separated from the bottle body when a flipping cap of the lid is opened, the flipping cap is easily locked without contact, resulting in poor user experience.

In view of the technical problems in the prior art, the present disclosure provides a water bottle. The water bottle comprises a bottle body and a bottle lid assembly. The bottle body define a water storage cavity therein and an opening at an upper portion thereof. The opening is connected to the bottle lid assembly. The bottle lid assembly is detachably connected to the bottle body. The bottle lid assembly comprises an upper lid and a lower lid. A first side of the upper lid is connected to the lower lid by a rotating shaft, and a second side of the upper lid is rotatable relative to the rotating shaft to open or close the bottle lid assembly. A movable gear cover is disposed in the lower lid. A gear is disposed on the movable gear cover. A locking assembly is disposed on the lower lid. A pressing column corresponding to the locking assembly is disposed on the upper lid. The pressing column rotates with the upper lid. When the upper lid rotates towards the lower lid, the pressing column pushes the locking assembly away from the gear to asynchronously rotate the lower lid and the movable gear cover. When the upper lid rotates away from the lower lid, the locking assembly moves towards the gear to synchronously rotate the lower lid and the movable gear cover.

By providing the locking assembly on the bottle lid assembly, the pressing column pushes the locking assembly when the upper lid is closed, so that the movable gear cover and lower lid are prevented from rotating synchronously, thereby preventing the bottle lid assembly from being separated from the bottle body. Once the bottle lid assembly is opened, the first spring resets, pushing the locking block into engagement with the gear, so that the movable gear cover and the lower lid are allowed to rotate synchronously, making the water bottle easy and safe to use. Additionally, a fingerprint unlocking function of a fingerprint unlocking assembly further enhances the safety of the water bottle. After unlocking, the second spring pushes the locking tongue back to lock the upper lid and the lower lid, facilitating use of the water bottler. Furthermore, in one optional embodiment, a waterproof assembly is mounted on the upper lid to prevent the straw from rotating when the upper lid rotates, preventing the upper lid from affecting the seal at the straw and improving sealing performance.

DETAILED DESCRIPTION

Embodiment 1

The embodiment of the present disclosure provides a water bottle. As shown in FIG. 1, the water bottle comprises a bottle body 1 and a bottle lid assembly 2. The bottle body 1 define a water storage cavity 10 therein and an opening at an upper portion thereof. The opening is connected to the bottle lid assembly 2.

An outer thread is disposed on an outer side of the opening of the bottle body1. An inner thread configured to be screwed with the outer thread is disposed on the bottle lid assembly 2. The bottle lid assembly 2 is detachably connected to the bottle body via a threaded connection. A liquid is allowed to be held in the water storage cavity 10 by opening the bottle lid assembly 2, and the liquid is allowed to be stored in the bottle body by closing the bottle lid assembly 2. Furthermore, the liquid in the water storage cavity 10 is allowed to be poured out for drinking by opening the bottle lid assembly 2. To enhance the thermal insulation of the bottle body 1, the bottle body 1 may be of a double-layer structure for better thermal insulation.

Specifically, as shown in FIG. 2, the bottle lid assembly 2 comprises an upper lid 20 and a lower lid 21 rotatably connected to the upper lid 20. The upper lid is connected to the lower lid by a rotating shaft 22. A fingerprint unlocking assembly 3 is disposed opposite to the rotating shaft. The fingerprint unlocking assembly 3 is configured to control opening and locking of the upper lid. To facilitate drinking the liquid in the water storage cavity, a straw 4 is disposed in a middle portion of the lower lid. The straw is extended into the bottle body and the liquid is allowed to be sucked out through the straw for drinking.

Furthermore, as shown in FIGS. 2-3 and 10-11, the lower lid 21 comprises an upper shell 210, a lower shell 211, and a movable gear cover 24 disposed between the upper shell 210 and the lower shell 211. A straw hole 243 is defined in a center of the movable gear cover. The straw 4 is placed at the straw hole. The inner thread is disposed on an inner side of the movable gear cover, and the inner thread of the movable gear cover is screwed with the bottle body. A sealing ring 7 is disposed in the inner thread. When in use, the sealing ring 7 contacts the opening of the bottle body to enhance sealing performance of the water bottle. An air hole 241 is defined on the movable gear cover 24 and is communicated with the water storage cavity 10. The air hole 241 is configured to discharge water vapor when a high-temperature liquid is poured into the water storage cavity, which facilitates opening of the upper lid.

Furthermore, as shown in FIGS. 2-3 and 7-11, in order to ensure that the bottle lid assembly 2 is allowed to be separated from the bottle body 1 only when the upper lid 20 is in an open state, a locking assembly 25 is disposed between the upper lid 20 and the lower lid 21. When the locking assembly is inserted to engaged with the movable gear cover 24, the lower lid and the movable gear cover rotate synchronously. When the locking assembly is not engaged with the movable gear cover, the movable gear cover does not rotate when the lower lid is rotated, and the bottle lid assembly 2 is unable to be removed from the bottle body 1. The movable gear cover 24 comprises a movable cover upper portion 242 and a movable cover lower portion. A radius of the movable cover upper portion is less than a radius of the movable cover lower portion, and the internal thread is disposed on an inner wall of the movable cover lower portion. A gear 240 is disposed on an outer peripheral wall of the movable cover upper portion 241. An upper flange 2113 corresponding to the gear 240 is disposed on the lower shell. The gear 240 is placed in the upper flange 2113. A limiting groove 2110 is extended from the upper flange 2113 and is corresponding to the locking assembly. The locking assembly is movable in the limiting groove and is able to be engaged with the gear 240 to achieve locking. At this time, the movable gear cover rotates synchronously with the lower lid. When the locking assembly is disengaged with the gear and moves in the limiting groove, the lower lid rotates asynchronously with the movable gear cover.

Furthermore, as shown in FIGS. 8-11, the locking assembly 25 comprises a locking block 250 and a first spring 251 corresponding to the locking block 250. A locking column 2502 is disposed on a front end of the locking block 250. A stressed column 2500 is disposed on the locking block 250,

When the stressed column 2500 is stressed, the stressed column 2500 drives the locking block to move away from the movable gear cover 24 in the limiting groove. At this time, the first spring 251 is compressed, and the locking block 2502 no longer engages with the gear 240, causing the movable gear cover and lower lid to rotate asynchronously. When the stressed column 2500 is released, the first spring resets to push the locking block toward the movable gear cover until the locking block is engaged with the gear. At this time, the movable gear cover and lower lid rotate synchronously. To prevent excessive resetting of the first spring, an upper step 2111 is disposed in the limiting groove 2110, and a lower step 2501 corresponding to the upper step 2111 is disposed on a lower end of the locking block. When the upper step contacts the lower step, the locking block moves to a maximum distance, and the locking column engages with the gear. Furthermore, to facilitate engagement of the locking column with the gear, a front end of the locking column is a tapered front end 2504. The a tapered front end 2504 has a small surface area, making it easier to engage with the gear. Alternatively, the a tapered front end 2504 is able to force the movable gear cover to rotate at a small angle, allowing the locking block to engage with the gear. At the same time, due to the configuration of the limiting groove, the locking column is only allowed to move in a length direction of the limiting groove, so that a moving direction of the locking column is stable.

Furthermore, as shown in FIGS. 4-6, a stressed column through hole 2108 corresponding to the stressed column is defined on the upper shell 210, the stressed column 2500 partially passes through the stressed column through hole 2108 and is movable in the stressed column through hole 2108.

A pressing plate 203 corresponding to the stressed column is disposed on the upper lid 20. When the upper lid rotates toward the lower lid via the rotating shaft, the pressing plate 203 moves closer to the locking block. When the pressing plate 203 contacts the locking block, the pressing plate 203 generate a thrust to push the locking block. Since a motion trajectory of the pressing plate 203 is a rotational path, the thrust is converted into a horizontal thrust on the locking block, causing the locking block to slide out to disengage with the gear. To enable the pressing plate to better push the locking block, the pressing plate has an arc-shaped surface 204. An upper end of the stressed column is an arc-shaped upper end 2503 correspondingly to achieve better force propulsion. A notch 2107 is defined in the upper shell 210, and one end of the limiting groove abuts against the notch, so that he upper and lower shells are able to rotate synchronously.

Furthermore, as shown in FIGS. 4-11, protruding columns 244 are disposed on an outer side of the movable gear cover 24, and slots 2112 matched with the protruding columns 244 are defined in the lower shell. The friction between the protruding columns 244 and the slots increases the rotational friction between the movable gear cover and the lower shell. When the movable gear cover and the lower shell rotate asynchronously, since the friction is large, a user may notice a current rotational state. A circular hole 2100 corresponding to the straw 4 is defined on a center of the upper shell, and a straw pressure plate 201 correspond to the straw is disposed on the upper shell. When the upper shell is closed, the straw pressure plate exerts a thrust on the straw to bend the straw 4, thereby reducing a volume of the bottle lid assembly. Support plates 202 are further disposed on one side of the straw pressure plate to enhance a structural strength of the straw pressure plate. A rotating shaft seat 2101 is disposed on one side of the upper shell, and a shaft hole 2102 is defined in the rotating shaft seat. The rotating shaft 22 is placed in the shaft hole and connected to the upper lid, so that the upper lid is rotatable relative to the lower lid to open or close the bottle lid assembly. A hanging lug 23 is disposed on one side of the lower lid. The water bottle is portable by connecting a hanging rope to the hanging lug 23, so that the water bottle is more convenient to carry. Further, the hanging lug is disposed below the rotating shaft seat, and a bulge 2103 is disposed on a lower end of the rotating shaft shaft seat. After opening the upper lid, when the bulge 2103 is in contact with the hanging lug 23, an opening angle of the upper lid 20 relative to the lower lid 21 is maximum. Moreover, the hanging lug and the bulge further prevent excessive opening of the upper lid from causing connection failure at the rotating shaft.

Furthermore, as shown in FIGS. 2-6 and 12-13, in order to facilitate the opening and closing of the upper lid, an accommodating chamber 2104 is defined in the lower lid, and a fingerprint unlocking assembly 3 is disposed in the accommodating cavity 2104. The fingerprint unlocking assembly 3 comprises a bracket 33, a fingerprint main board 32 disposed in the bracket 33, and a display screen 31 disposed in the bracket 33. The display screen is configured to display a temperature of the liquid in the water bottle. Furthermore, a fingerprint unlocking area 30 is defined on the display screen 31. The bottle lid assembly further comprises a control board 6 and a battery 5. The control board 6 and the battery 5 are connected to the fingerprint main board. The fingerprint unlocking assembly is powered by the battery, and a charging port is defined on the control board to charge the battery 5. The fingerprint unlocking assembly 3 further comprises a motor 34 and a cam 35 that rotates synchronously with the motor 34. When the fingerprint unlocking area receives correct fingerprint information, the motor 34 rotates to cause the cam 35 to rotate synchronously. The cam 35 comprises a pushing portion 350, and the fingerprint unlocking assembly comprises a locking tongue 36 corresponding to the pushing portion. A plugging column is disposed on the upper lid. A plugging hole 360 is defined on the locking tongue 36, and a buckle 361 is disposed in the plugging hole 360. A buckling hole 200 corresponding to the buckle 361 is disposed on the upper lid. When the upper lid is closed, the plugging column enters the plugging hole until the buckle is buckled with the buckling hole. In this way, the upper lid and the lower lid are buckled and locked. When the fingerprint unlocking area receives the correct fingerprint information, the pushing portion rotates to push the locking tongue to move, so as to unlocking the buckle and the buckling hole. At this time, the upper lid is opened. A second spring 37 is disposed on one end of the locking tongue. The pushing portion pushes the locking tongue to move, so that the second spring is compressed. After the upper lid is opened, the second spring resets and pushes the locking tongue back to an initial position. When the upper lid is closed, the plugging column is plugged into the plugging hole. The plugging column generates a pushing force on the buckle, causing the locking tongue to move until the pushing force disappears. The second spring resets the locking tongue and causes the buckle to enter the buckling hole, so that the upper lid is closed and locked. To facilitate the movement of the locking tongue, a sliding column 362 is disposed on a lower end of the locking tongue. The sliding column 362 has a contact slope 363. The pushing portion contacts the contact slope 363 and pushes the locking tongue. Stopping portions 364 are provided on two sides of the locking tongue. A locking tongue sliding groove 2106 corresponding to the stopping portions is disposed in the accommodating chamber 2104. In this way, the locking tongue is only allowed to move in the locking tongue sliding groove 2106. A square hole 2105 corresponding to the plugging hole is defined on the lower lid.

When the upper lid 20 is in the closed state, the plugging column is plugged into the plugging hole 360. At this time, the buckle 361 is locked with the buckling hole 200 to lock the upper lid and the lower lid. At this time, the pressing plate 203 pushes the locking block 250 to move and compresses the locking spring 251. The locking column 2502 is not engaged with the gear. Since the locking assembly 25 is not in contact with the gear, the lower lid and the movable gear cover are unable to rotate synchronously. At this time, the bottle lid assembly 2 is unable to be removed from the bottle body by rotating the lower lid 21.

When a correct fingerprint is placed on the fingerprint unlocking area 30, the fingerprint main board 32 recognizes the correct fingerprint, the motor 34 rotates to drive the cam 35 to rotate, and pushes the sliding column 362 to move through the pushing portion 350, so that the locking tongue 36 moves. When the locking tongue moves and drives the buckle 361 to move to separate from the buckling hole, the upper lid 20 is opened. At this time, the second spring 37 is compressed. After the upper lid is opened, the second spring resets the lock tongue. After the upper lid is opened, a stopping force of the pressing column on the stressed column 2503 disappears, the first spring 251 resets and pushes the locking block 250 to reset. At this time, the locking column 2502 is engaged with the gear. When the lower lid is rotated, the movable gear cover and the lower lid rotate synchronously under the action of the locking assembly and the gear, and the bottle lid assembly is allowed to be removed from the bottle body and liquid is able to be introduced into the water storage cavity. After opening the upper lid, the straw is configured to drink the liquid in the water storage cavity. After drinking, the upper lid 20 is closed, and the straw pressing plate 201 presses the straw. At the same time, the pressing column 203 pushes the stressed column 2500 to move the locking block until the locking column 2502 moves to disengage with the gear. At this time, the movable gear cover and the lower lid rotate asynchronously, and the upper lid is rotated until the plugging column is plugged into the plugging hole 360. The plugging column pushes the locking tongue 36 to move and compresses the second spring 37. When the plugging column continues to move to make the buckle 361 and the buckling hole 200 being located at a same horizontal position, the plugging column is unable to generate the thrust on the buckle, and the second spring resets to push the locking tongue to move the buckle, so that the buckle is locked in the buckling hole. At this time, the upper lid is locked with the lower lid, and when the upper lid is rotated, the lower lid and the movable gear cover rotate asynchronously, and the bottle lid assembly is unable to be removed from the bottle body.

Embodiment 2

The embodiment of the present disclosure provided a water bottle. The difference from Embodiment 1 is that in Embodiment 1, when the upper lid 20 and the lower lid 21 are closed, the straw 4 needs to be pressed by the straw pressing plate 201. In this case, the straw is not well sealed when rotating the bottle lid assembly, which causes water leakage. To solve the problem, as shown in FIGS. 14-15, the straw 4 is disposed perpendicular to the lower lid 21. In this case, there is no need to provide the straw pressing plate on the upper lid. Instead, a waterproof assembly 206 is disposed in the middle portion of the upper lid and is corresponding to a position of the straw. A waterproof assembly cavity 205 corresponding to the waterproof assembly is defined in the middle portion of the upper lid. The waterproof assembly is placed in the waterproof assembly cavity, and a lower end of the waterproof assembly is in contact with the upper end of the straw to seal the straw. In this case, the straw is not rotated when rotating the bottle lid assembly.

Furthermore, as shown in FIGS. 16-17, the waterproof assembly cavity 205 has an annular cavity wall 2050. A sliding groove 2051 is defined in the annular cavity wall 2050. The waterproof assembly is placed in the waterproof assembly cavity, and the waterproof assembly comprises a waterproof silicone piece 2061, and a fixing piece 2060. The fixing piece 2060 is configured to connect the waterproof silicone piece 2061 to the upper lid. A connecting hole 20600 is defined in a center of the fixing piece 2060. A connecting column 20610 corresponding to the connecting hole is disposed on a center of the waterproof silicone piece. The connecting column passes through the connecting hole to connect the waterproof silicone piece 2061 to the fixing piece 2060. Moreover, a clamping column 20611 is formed on the connecting column 20610, and a radius of the clamping column 20611 is greater than a radius of the connecting hole. In order to allow the waterproof assembly to slide relative to the upper lid, clamping teeth 20601 are disposed on the fixing piece. The clamping teeth is slidable in the sliding groove 2051, and gaps 20602 are defined between the clamping teeth to facilitate sliding of the clamping teeth 20601. The waterproof assembly is able to be removed from the upper lid for cleaning. A lower end of the waterproof silicone piece forms a sealing surface 20612. The sealing surface of the waterproof silicone piece may be spherical to fit with the straw, thereby increasing the sealing performance of the waterproof assembly on the straw without affecting the rotation.
