Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation cups, in particular to a heat preservation cup with a self-locking function. Background Art

[0002] As is well known, heat preservation cups are relatively common daily necessities in daily life. Usually in winter, they are used to keep drinking water warm for storage, so that when the user drinks later, the water still has a certain temperature. For the structure of the heat preservation cup itself, it mainly includes a cup body and a cup lid connected by threads. The cup body plays the main role of heat preservation, while the cup lid mainly serves as a seal, and the cup lid needs to be opened when in use.

[0003] At present, in order to facilitate consumers to drink water, in the structure between the existing heat preservation cup and the cup lid, a flip cover and a drinking port blocked by the flip cover are provided on the bottle cap. When not drinking water, the flip cover is closed, and when drinking water, the flip cover is directly opened. This form is more convenient compared to the threaded opening and closing of the cup lid. Therefore, this type of heat preservation cup has become a popular structure among consumers. However, now consumers have further considerations about the safety of private drinking heat preservation cups. To prevent others from opening their heat preservation cups, a fingerprint recognition lock is set at the flip cover, so that others can be prevented from opening the heat preservation cup and the safety of the heat preservation cup in public places can be improved. But the existing anti-opening protection is only for the opening of the flip cover, and for the restriction between the cup lid and the cup body, it still only relies on simple threaded locking, which obviously does not meet the safety protection requirements in public places. For consumers with such concerns, further improvement is obviously needed. Summary of the Utility Model

[0028] As Figures 1 to 7 shown, a heat-insulated cup with a self-locking function provided in this embodiment includes:

[0029] A cup body 1 for containing drinking water, and a threaded port 11 is provided at the cup mouth;

[0030] Cup lid 2, the cup lid 2 includes an outer sleeve 21 and an inner sleeve 22. The bottom of the inner sleeve 22 is threadedly connected to the threaded port 11 of the cup body 1. An outlet nozzle 221 communicating with the inner cavity of the cup body 1 is provided at the upper end of the inner sleeve 22. A circle of card slots 222 is evenly arranged on the outer wall of the outlet nozzle 221. The outer sleeve 21 is installed on the inner sleeve 22 and wraps the inner sleeve 22, and the outer sleeve 21 can rotate idly relative to the inner sleeve 22. A sliding plate 212 that can slide along the slideway 211 is placed in the inner cavity of the outer sleeve 21 relative to the card slot 222 through the slideway 211. A top lock block 213 that can be inserted into the card slot 222 in alignment is provided on the sliding plate 212. At least one spring 214 is arranged between the sliding plate 212 and the inner wall of the slideway 211. Under the action of the spring 214, the top lock block 213 always remains inserted into the card slot 222. A trigger block 215 is provided on the upper end surface of the sliding plate 212. The top of the trigger block 215 is a slope surface. Avoidance holes are provided at the positions of the outer sleeve 21 relative to the trigger block 215 and the outlet nozzle 221, and the top of the outlet nozzle 221 is placed outside the outer sleeve 21;

[0031] Flip cover 3, the flip cover 3 is hinged to the outer sleeve 21 and is locked by a fingerprint lock 4. A top pressing block 31 is provided on the lower end surface of the flip cover 3 and directly above the avoidance hole. After the flip cover 3 is closed on the cup lid 2, the top pressing block 31 gradually presses the slope surface of the trigger block 215, forcing the sliding plate 212 to move in the other direction of the slideway 211, so that the top lock block 213 disengages from the card slot 222.

[0032] In the design of this embodiment, mainly by separating the cup lid 2, the cup lid 2 is composed of an outer sleeve 21 and an inner sleeve 22. Through the disengagement and locking of the card slot 222 and the top lock block 213 between the outer sleeve 21 and the inner sleeve 22, the outer sleeve 21 rotates idly or drives the inner sleeve 22 to rotate together. Combined with the linkage with the flip cover 3, the cup lid 2 and the cup body 1 can be automatically locked. When the flip cover 3 is not unlocked, the threaded connection between the cup lid 2 and the cup body 1 cannot be released, making it safer and more reliable to use in public places.

[0033] During specific use, by default, the flip cover 3 is closed on the cup lid 2, covering the water outlet nozzle 221 as a whole. At this time, the pressing block 31 on the flip cover 3 is inserted into the corresponding avoidance hole, and relying on the inclined plane of the trigger block 215, the slide plate 212 is pushed to the other end of the slideway 211, and the spring 214 is in a compressed state. After the slide plate 212 is pushed to the other end of the slideway 211, the top lock block 213 disengages from the latch with the card slot 222. In this way, only a rotational connection exists between the outer sleeve 21 and the inner sleeve 22, and the outermost outer sleeve 21 can only rotate idly and cannot drive the inner sleeve 22 to rotate together. As a result, the threaded connection between the inner sleeve 22 and the cup body 1 cannot be unscrewed, thus preventing others from privately opening the cup lid 2 without fingerprint unlocking, achieving the effect of ensuring safety. When the cup lid 2 needs to be opened, first, after successful fingerprint recognition, the flip cover 3 is opened. Then, the pressing block 31 disengages from the top contact with the trigger block 215, and the originally compressed spring 214 will push the slide plate 212 to move in the original direction. After the movement is completed, the top lock block 213 will snap into one of the card slots 222, thereby connecting the slide plate 211 to the water outlet nozzle 221 of the inner sleeve 22, that is, connecting the inner sleeve 22 and the outer sleeve 21. Thus, when the outer sleeve 21 is rotated externally, the inner sleeve 22 can be rotated, thereby achieving the opening of the cup lid 2.

[0034] Furthermore, regarding the connection structure between the outer sleeves 21, specifically, it mainly relies on an annular groove 216 provided on the inner wall of the outer sleeve 21, and an annular protrusion 223 is provided on the inner sleeve 22. The annular protrusion 223 is placed in the annular groove 216 to enable the outer sleeve 21 to meet the rotation requirements.

[0035] Further, regarding the structure of the flip cover 3 of this embodiment, the flip cover 3 of this embodiment is internally provided with a circuit board 32, an inner frame 33, and a battery (not shown in the figure). The fingerprint lock 4 includes a fingerprint recognition module 41, a motor 42, and a transmission mechanism. The circuit board 32, the battery, the motor 42, and the transmission mechanism are all installed on the inner frame 33. The fingerprint recognition module 41 is installed on the case of the flip cover 3. The battery, the fingerprint recognition module 41, and the motor 42 are all electrically connected to the circuit board 32. An eccentric toggle lever 43 is installed on the rotating head of the motor 42. The transmission mechanism includes a shaft rod 44 axially connected to the inner frame 33. One end of the shaft rod 44 is provided with a first toggle lever 45 in an "L" shape. The side of the first toggle lever 45 abuts against the eccentric toggle lever 43. The other end of the shaft rod 44 is provided with a second toggle lever 46 in an "L" shape. The inner frame 33 is axially connected with a latch block 47 in the vertical direction at the corresponding position of the second toggle lever 46. A torsion spring 48 is provided at the axial connection of the latch block 47. Under the action of the torsion spring 48, one end of the latch block 47 always keeps in contact with the second toggle lever 46. The other end of the latch block 47 is placed outside the flip cover 3 and is provided with a hook. A lock port 49 is provided on the surface of the outer casing 21. The orientation of the lock port 49 corresponds to the hook. Among them, when unlocking, the consumer only needs to perform fingerprint recognition. After the fingerprint recognition module 41 successfully recognizes the fingerprint, the motor 42 will be driven (it should be noted that the rotation mode of the motor 42 in this embodiment is a swinging form, not a full rotation), that is, the eccentric toggle lever 43 is driven to swing. Because the first toggle lever 45 at one end of the shaft rod 44 contacts the eccentric toggle lever 43, after the eccentric toggle lever 43 swings, the first toggle lever 45 will be forced to shift, and then the second toggle lever 46 at the other end of the shaft rod 44 will also shift, thereby pushing the latch block 47 to rotate, so that the hook at the other end of the latch block 47 disengages from the lock port 49, and thus the flip cover 3 can be opened. When locking, after the motor 42 resets, under the action of the torsion spring 48 at the latch block 47, the hook hooks into the lock port 49 again.

[0036] Further, because it is necessary to meet the consumer's drinking water requirements, the water outlet nozzle 221 needs to extend beyond the cup cover 2, that is, beyond the outer casing 21. Therefore, in order to better store the water outlet nozzle 221, a receiving cavity 34 is provided at the bottom of the flip cover 3 of this embodiment at the position of the water outlet nozzle 221. After the flip cover 3 is closed, the water outlet nozzle 221 is placed in the receiving cavity 34.

[0037] Further, in order to prevent the water of the water outlet nozzle 221 from leaking out after the flip cover 3 is closed, a soft rubber plug 35 for blocking the water outlet nozzle 221 is provided in the receiving cavity 34 of this embodiment.

[0038] Further, to facilitate the automatic pop-up of the flip cover 3 after unlocking, at least one torsion spring 48 for providing the force required to pop open the flip cover 3 is provided at the hinge joint between the flip cover 3 and the outer casing 21 in this embodiment.

[0039] Further, the battery in this embodiment is a rechargeable battery, a charging port 36 is provided on the flip cover 3, and the charging port 36 is electrically connected to the circuit board. The charging port 36 in this embodiment is a magnetic charging port, and such a design can effectively improve the product grade.

[0040] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
