Description

Technical Field

[0001] This utility model belongs to the field of daily necessities and equipment, and relates to thermos cups, and in particular to a self-locking thermos bucket. Background Technology

[0002] A thermos is a water container made of ceramic or stainless steel with a vacuum layer. It has a lid that is tightly sealed. The vacuum insulation layer slows down the heat dissipation of the liquid inside, thus achieving the purpose of keeping it warm. The thermos evolved from the thermos bottle, and the principle of heat preservation is the same. It is just that people made the bottle into a cup for convenience.

[0003] For example, the thermos cup with publication number CN216316916U includes a cup body and a lid on the cup body. The lid has a flip-top cover. The lid has a cavity on its side and a through hole on its upper side for the slot of the flip-top cover. A horizontal strip hole is opened on the side of the press button. A pin passes through the strip hole to install the press button into the cavity. The rear end of the press button contacts the inner wall of the cavity through a spring. The hollow part of the press button has a locking protrusion that matches the slot on the side of the flip-top cover.

[0004] However, the above-mentioned thermos cups require manual closing of the lid after drinking to seal the drinking spout, which is rather inconvenient. Utility Model Content

[0005] This utility model provides a self-locking insulated bucket that can automatically close the drinking spout after drinking.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a self-locking insulated bucket, including a cup body and a cup lid detachably connected to the cup body. The cup lid is provided with a drinking spout and a suction nozzle fixedly connected to the drinking spout. The suction nozzle includes a fixed part and a movable part slidably connected to the fixed part. The movable part slides within the fixed part. Several pushing blocks are fixedly connected to the inner side wall of the fixed part. Two closing plates are hinged to the movable part above the pushing plate. A spring is provided between the fixed part and the movable part. When the movable part slides downward, the pushing blocks push the closing plates to rotate and the spring deforms to open the drinking spout. When the movable part slides upward, the spring pushes the movable part to reset and the closing plates rotate to close the drinking spout.

[0007] A further preferred embodiment of this utility model is: a sliding groove is provided on the fixed part, and the movable part slides within the sliding groove.

[0008] A further preferred technical solution of this utility model is as follows: a plurality of limiting plates passing through the fixed part are fixedly connected to the movable part, and the fixed part is provided with a limiting groove to facilitate the sliding of the limiting plate. The spring is located between the sliding groove and the limiting plate. When the limiting plate slides down, the spring deforms.

[0009] A further preferred embodiment of this utility model is that a push plate, which is a ring, is connected to each of the plurality of limiting plates.

[0010] A further preferred embodiment of this utility model is as follows: the closing plate is connected to the inner wall of the movable part by a pin, and a torsion spring for driving the closing plate to rotate is sleeved on the pin. When the drinking spout is opened, the torsion spring deforms.

[0011] A further preferred technical solution of this utility model is as follows: sealing gaskets are provided on the opposite surfaces of the two closing plates. The sealing gaskets are elastic, and when the drinking spout is closed, the sealing gaskets abut against each other and deform.

[0012] A further preferred embodiment of this utility model is as follows: the movable part is fixedly connected to an abutting block below the closing plate, the abutting block and the pushing block are staggered, and when the two closing plates abut against each other, the closing plate and the abutting block form an abutment.

[0013] A further preferred embodiment of this utility model is that the closing plate is a semi-circular plate.

[0014] A further preferred embodiment of this invention is that there is a gap between the pushing block and the closing plate.

[0015] A further preferred embodiment of this utility model is that the top end of the fixing part is provided with an arc-shaped surface.

[0016] Compared with the prior art, this utility model includes a cup body and a cup lid. The cup lid is provided with a drinking spout and a sippy nozzle. The sippy nozzle includes a fixed part and a movable part. The movable part slides inside the fixed part. Several pushing blocks are fixedly connected to the inner side wall of the fixed part. Two closing plates are hinged to the movable part above the push plate. A spring is provided between the fixed part and the movable part. When the movable part slides down, the pushing blocks push the closing plates to rotate and the spring deforms to open the drinking spout. Therefore, after drinking, the deformed spring pushes the movable part to return to its original position. At this time, the closing plates separate from the pushing blocks and rotate downward due to gravity, closing the drinking spout. This achieves the function of automatically closing the drinking spout after drinking, improving the convenience of using the thermos. Attached Figure Description

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0026] Figures 1-4As shown, a self-locking insulated bucket includes a cup body 1 and a cup lid 2 detachably connected to the cup body 1. The cup lid 2 is provided with a drinking spout 14 and a sippy nozzle fixedly connected to the drinking spout 14. The sippy nozzle includes a fixed part 11 and a movable part 3 slidably connected to the fixed part 11. The movable part 3 slides inside the fixed part 11. The top of the fixed part 11 is provided with an arc-shaped surface 16, which makes drinking more comfortable. Several pushing blocks 6 are fixedly connected to the inner side wall of the fixed part 11. The movable part 3 is hinged to two closing plates 5 above the push plate 4. There is a gap between the pushing blocks 6 and the closing plates 5. The closing plates 5 are semi-circular plates.

[0027] Figures 2-4 As shown, when in use, the movable part 3 is pressed down by the mouth. As the movable part 3 slides, the distance between the closing plate 5 and the pushing block 6 gradually decreases until the pushing block 6 pushes the closing plate 5 to rotate. At this time, the drinking spout 14 opens as the closing plate 5 rotates, making it easier to drink. After drinking, the movable part 3 is pulled up. At this time, the distance between the closing plate 5 and the pushing block 6 gradually increases and the closing plate 5 rotates in the opposite direction due to gravity, thereby closing the drinking spout 14. This design can close the drinking spout 14 after drinking, thereby improving the convenience of using the thermos.

[0028] Figures 2-5 As shown, the closing plate 5 is connected to the inner wall of the movable part 3 by a pin 15. A torsion spring 8 is sleeved on the pin 15 to drive the closing plate 5 to rotate. When the drinking spout 14 is opened, the torsion spring 8 deforms. By setting the torsion spring 8, when the closing plate 5 is separated from the push block 6, the deformed torsion spring 8 drives the closing plate 5 to rotate in the opposite direction, thereby resetting and closing the drinking spout 14, which plays the role of braking the closing of the drinking spout 14. At the same time, it can prevent the closing plate 5 from getting stuck.

[0029] Figures 2-4 As shown, sealing gaskets are provided on the opposite surfaces of the two closing plates 5. The sealing gaskets are elastic. When the drinking spout 14 is closed, the sealing gaskets abut against each other and deform. By setting the sealing gaskets, the sealing effect of the closing plates 5 can be improved, and water leakage can be avoided.

[0030] Figures 2-4 As shown, the movable part 3 is fixedly connected to the abutment block 7 below the closing plate 5. When the two closing plates 5 abut against each other, the closing plate 5 and the abutment block 7 form an abutment. Therefore, when the deformed torsion spring 8 drives the closing plate 5 to reset, the abutment block 7 can limit the rotation range of the closing plate 5, preventing the drinking spout 14 from opening due to excessive rotation range, thus ensuring the closing effect of the closing plate 5. Furthermore, since the abutment block 7 and the push block 6 are staggered, the abutment block 7 can be prevented from affecting the normal use of the push block 6 when the closing plate 5 slides up and down.

[0031] Figures 2-4As shown, a groove 9 is provided on the fixed part 11, and the movable part 3 slides within the groove 9. Therefore, when sliding, the groove 9 restricts the movement trajectory of the movable part 3, preventing the movable part 3 from deviating during sliding and ensuring the normal use of the closing plate 5.

[0032] Figures 2-4 As shown, a plurality of limiting plates 13 passing through the fixed part 11 are fixedly connected to the movable part 3. The fixed part 11 is provided with a limiting groove 12 to facilitate the sliding of the limiting plate 13. By setting the limiting plate 13, the vertical sliding range of the movable part 3 can be limited, and the movable part 3 can be prevented from separating from the fixed part 11 when sliding.

[0033] Figures 2-4 As shown, a spring 10 is provided between the fixed part 11 and the movable part 3. The spring 10 is located between the slide groove 9 and the limiting plate 13. When the limiting plate 13 slides down, the spring 10 deforms. After drinking, the deformed spring 10 can push the limiting block and the movable part 3 to automatically reset, thus facilitating the next drinking. This design improves the ease of use of the thermos.

[0034] Figures 2-4 As shown, several limiting plates 13 are all connected to a push plate 4. The push plate 4 is a ring. This design increases the contact area between the movable part 3 and the mouth. The mouth can push the push plate 4 to drive the movable part 3 to slide, which improves the ease of operation.

[0035] The above describes a self-locking insulated bucket provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
