Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, and particularly relates to a self-locking cup cover and a water cup. Background Art

[0002] In the prior art, the cup covers of water cups (including thermos cups and similar products) generally do not have a self-locking structure; although some cup covers have a self-locking structure, it is usually just a button-type self-locking structure (for example, the self-locking button cup cover disclosed in the application publication number CN 117502881A). This button-type self-locking structure can only prevent accidental touch, and anyone other than the user of the water cup can open the cup cover. It can be seen that the safety of the existing cup cover self-locking structure needs to be further improved. In view of the above technical problems, this application proposes a new technical solution, which can not only achieve self-locking of the cup cover, but also further improve its safety. Summary of the Utility Model

[0005] A self-locking cup cover includes an inner cover and an outer cover. The inner cover is provided with a concave cavity, and a plurality of insertion holes are arranged on the bottom plate of the concave cavity; an installation seat, a main board, a motor, a battery, and an insertion rod are arranged inside the outer cover. The motor is arranged on the installation seat, and the motor is used to drive the insertion rod to insert into the insertion hole or withdraw from the insertion hole; the main board is connected with at least one of a Bluetooth module, a fingerprint recognition module, a UWB module, and an NFC module; a one-way rotation mechanism is arranged between the inner cover and the installation seat.

[0006] Further, in the self-locking cup cover, the one-way rotation mechanism is a ratchet mechanism, the ratchet of the ratchet mechanism is connected with the inner cover, and the pawl is connected with the installation seat.

[0007] Further, in the self-locking cup cover, the insertion holes are distributed in a ring shape; the distance between any two adjacent insertion holes is equal.

[0008] Further, in the self-locking cup cover, the sizes of the respective insertion holes are equal.

[0009] Further, in the self-locking cup cover, an eccentric member is connected to the output shaft of the motor.

[0023] The present utility model provides a self-locking cup lid and a water cup. To make the purpose, technical solution and effect of the present utility model clearer and more definite, the present utility model will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Please refer to Figures 1-8 , the present utility model provides a self-locking cup lid and a water cup. The drawings are only used to explain the structural principle and are not in proportion to the actual product. The drawings only show the structures related to the inventive points of the present application, and some conventional structures are not specifically shown. For the convenience of description, some orientation words are inevitably used in this article, but these orientation words are not intended to limit the present application, because they can be set in different directions in actual applications. The "multiple" (or "several") described in this article refers to an indefinite quantity, because the number of the structures referred to is not the inventive point, so no specific limitation is made.

[0025] A self-locking cup lid includes an inner lid 7 and an outer lid 1. The inner lid is provided with a concave cavity 701, and a plurality of jacks 702 are arranged on the bottom plate of the concave cavity; an installation seat 2, a main board (not shown in the figure), a motor 3, a battery (not shown in the figure), and a plug rod 41 (as Figure 6 shown) are arranged inside the outer lid. The motor is arranged on the installation seat, and the motor is used to drive the plug rod to insert into or withdraw from the jack; the main board is connected to at least one of a Bluetooth module, a fingerprint recognition module, a UWB module, and an NFC module; a one-way rotation mechanism is arranged between the inner lid and the installation seat. The above NFC refers to "Near Field Communication (i.e., near field communication)", and users can unlock the cup lid through products such as mobile phones and NFC cards provided with NFC modules. The above UWB refers to "UltraWide Band (i.e., ultra-wideband)". Setting the UWB module can achieve the function of precise ranging, and products such as mobile phones or watches provided with the UWB module can unlock the cup lid within a certain distance.

[0026] The outer lid and the inner lid are rotatably connected; there is no relative rotation between the installation seat and the outer lid. The above battery and motor are electrically connected to the main board respectively. In actual applications, users can control the rotation of the motor through one or more of Bluetooth, fingerprint recognition, and NFC. A charging interface 19 is arranged on the outer lid to facilitate charging the battery.

[0027] As Figure 2 shown, preferably, the one-way rotation mechanism is a ratchet mechanism. The ratchet 72 of the ratchet mechanism is connected to the inner lid, and the ratchet pawl 71 is connected to the installation seat. The inner lid is provided with a central through hole 703 to facilitate the connection between the ratchet pawl and the mounting plate.

[0028] As Figure 2As shown, preferably, the ratchet is an internal-tooth ratchet. The advantages of such a setting are as follows: (1) The internal-tooth ratchet can be directly formed on the lower surface of the bottom plate of the concave cavity, enabling the ratchet and the bottom plate of the inner cover to be integrally formed; (2) The mounting seat and the inner cover can be coaxially arranged, and the pawl can extend into the ratchet, saving the installation space of the ratchet mechanism.

[0029] In practical applications, a baffle 79 is provided at the bottom of the bottom plate of the concave cavity (as Figure 1 shown), and the baffle completely shields the ratchet. This setting enables the cup lid to be convenient for users to drink water with the cup lid, and the water will not come into contact with the internal structure of the cup lid (ratchet mechanism, mounting seat, main board, motor, etc.).

[0030] As Figure 7 shown, preferably, the jacks are annularly distributed, and the distance between any two adjacent jacks is equal. This setting makes the chance of the insertion rod inserting into one of the jacks equal, that is: when the mounting seat rotates within a certain range, the insertion rod has the opportunity to insert into a jack. Because when unlocking, the motor drives the insertion rod to move downward, it is possible that the insertion rod does not exactly align with the jack. At this time, the user slightly rotates the outer cover (the outer cover will drive the mounting seat to rotate), so that the insertion rod aligns with an adjacent jack (such as the state shown in Figure 8 ), and the insertion rod can be inserted into the adjacent jack under the action of the motor.

[0031] Preferably, the sizes of the respective jacks are equal. This setting makes it easy for the insertion rod to insert into the jack. The attached drawing shows that the insertion rod is a round rod and the jack is a round hole, but this is only a preferred solution. The insertion rod and the jack can also be of other shapes, as long as it is ensured that the insertion rod can be smoothly inserted into the jack.

[0032] As Figure 6 shown, further, an eccentric member 39 is connected to the output shaft of the motor 3.

[0033] Preferably, the eccentric member 39 is an elliptical wheel. That is, when the motor rotates 90°, the insertion rod inserts into the jack, and when the motor rotates another 90°, the insertion rod withdraws from the jack. This setting facilitates the motor to precisely control the stroke of the insertion rod.

[0034] Please continue to refer to Figure 6 , further, a rod socket 42 is connected to the mounting seat, and the insertion rod passes through the rod socket; the elliptical wheel abuts against the top 421 of the rod socket. The motor drives the elliptical wheel to rotate, further driving the rod socket to move in the up and down directions, and finally realizing the up and down movement of the insertion rod. A plurality of springs 429 are provided downward on the rod socket, and after the springs are compressed, they will apply an upward force to the rod socket to ensure that the rod socket (and the insertion rod) can move upward smoothly after the motor rotates a certain angle.

[0035] The present utility model also provides a water cup, which includes a cup body 9. Different from the prior art, it further includes the self-locking cup lid described above. Since the cup body is not the key point of the present utility model, the structure of the cup body will not be specifically drawn.

[0036] The cup body and the inner lid are connected by threads, that is: the cup body is provided with external threads, and the inner wall of the inner lid is provided with internal threads ( Figure 1 and Figure 2 the internal threads can be directly observed). Since this is a conventional setting, the present application will not specifically limit it. Since the helix direction of the threads does not change the essence of the technical solution of the present application.

[0037] For the convenience of understanding, the working principle of the self-locking cup lid is further explained above. For the convenience of elaboration, the following takes the connection between the cup body and the inner lid by right-handed threads (that is: when observed from top to bottom, the cup lid can be tightened clockwise) as an example for illustration.

[0038] Since the inner lid and the cup body are connected by threads, the cup lid must be rotated by driving the inner lid to be opened. However, the inner lid is arranged inside the outer lid, and the user cannot directly rotate the inner lid. What the user directly rotates is the outer lid. Since the outer lid is connected to the mounting seat, when the outer lid is rotated, the outer lid and the mounting seat rotate together. The following will be described in different cases according to the position of the insertion rod.

[0039] (1) When the cup lid is in the self-locking state (at this time, the insertion rod is not inserted into the jack in the concave cavity of the inner lid), the mounting seat and the inner lid are connected by a ratchet mechanism. Since the ratchet mechanism is a one-way rotation mechanism, at this time, if the mounting seat rotates clockwise, the mounting seat and the inner lid will rotate clockwise together; if the mounting seat rotates counterclockwise, the inner lid will not rotate. That is: in the self-locking state of the cup lid, the user can screw the outer lid clockwise, and the outer lid, the mounting seat, and the inner lid will rotate clockwise together, so that the inner lid and the cup body are tightened; if the user screws the outer lid counterclockwise, the outer lid and the mounting seat are in an "idle rotation" state, and the inner lid does not rotate, so the cup lid cannot be opened.

[0040] (2) When the user unlocks the cup lid by means of Bluetooth, fingerprint recognition or NFC, etc. (at this time, the insertion rod is inserted into one of the jacks in the concave cavity). Due to the function of the insertion rod, the mounting seat and the inner lid are limited in the circumferential direction and cannot rotate relative to each other. If the user rotates the outer lid counterclockwise, the outer lid and the mounting seat will no longer "idle rotate", but will drive the inner lid to rotate counterclockwise together, thus opening the cup lid.

[0041] The aforementioned Bluetooth module, fingerprint recognition module, UWB module, and NFC module are used to control the rotation of the motor, thereby controlling the self-locking or unlocking of the cup lid. For example, the user can control the rotation of the motor through Bluetooth connection between the mobile phone and the cup lid, or control the rotation of the motor by using fingerprint recognition, or control the rotation of the motor by using a product equipped with a UWB module or an NFC module. Since the Bluetooth module, fingerprint recognition module, UWB module, and NFC module themselves are prior arts, and this application does not aim to propose a new Bluetooth module, fingerprint recognition module, UWB module, or NFC module, nor does it aim to propose a new circuit structure or computer program. Therefore, this application does not specifically define the Bluetooth module, fingerprint recognition module, UWB module, NFC module, and circuit structure.

[0042] It can be understood that for those of ordinary skill in the art, equivalent substitutions or changes can be made according to the technical solution and the inventive concept of the present utility model, and all such changes or substitutions should fall within the protection scope of the present utility model.
