[0023] The present invention provides a children's water cup. To make the purpose, technical solution and effect of the present invention clearer and more specific, the present invention is further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] See also Figures 1 to 10 , the utility model provides a children's water cup. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual product. The accompanying drawings only show the structures related to the invention point of this application (for example: batteries and main boards, etc.), and some conventional structures are not specifically drawn. The terms "first", "second", etc. described herein are merely different names for similar structures for the convenience of explanation, and are not intended to limit this application. For the sake of convenience, this article inevitably uses some directional words, but these directional words are not intended to limit this application, because they can be set to different directions in actual applications. The "multiple" (or "several") mentioned herein refers to an indefinite number, because the number of the structures referred to is not an invention point, and therefore is not specifically limited.

[0025] The children's water cup comprises a cup body 90 and a cup cover, wherein the cup cover comprises an inner cover 11, an outer cover 12 and a flip cover 13; the inner cover and the outer cover are rotatably connected, the inner cover is provided with a plurality of jacks 111, the outer cover is provided with an insertion rod 51, a motor 31, a battery and a main board (not shown in the figure), the motor is used to drive the insertion rod to insert into the jack 111 or withdraw from the jack; the flip cover is provided with a hanging hole 130 (such as Figure 6 As shown), a hook 41 is provided on the outer cover 12, and the motor is used to drive the hook to connect or separate with the hanging hole. Figure 4 and Figure 5 As shown, a plurality of slots 112 are provided in the inner cover, each of which is provided with a first inclined surface 1121 along the circumferential direction, a block seat 21 is provided in the outer cover, a block 23 is provided downwardly on the block seat, a first spring 22 is provided between the block and the block seat, and the block is provided with a second inclined surface 231.

[0026] In practical applications, the children's cup is further provided with a straw 91 (such as Figure 2 As shown in the figure, the straw is inserted into the cup body, and the top of the straw extends from the top of the outer cover. The above-mentioned motor and battery are connected to the main board respectively. A charging interface 129 (as shown in the figure) is provided on the outer cover. Figure 1 to charge the battery.

[0027] The first inclined surface 1121 of the slot and the second inclined surface 231 of the block have the same inclination angle, and the two can fit together. The purpose of this setting is that when the insertion rod is not inserted into the socket, the outer cover and the inner cover can only rotate synchronously in one direction (that is, they can only be tightened, not loosened). Under the elastic force of the first spring, the block is pressed downward into the corresponding slot. When the insertion rod is not inserted into the socket, if the outer cover is tightened (clockwise when viewed from top to bottom), the inner cover will rotate together until the inner cover and the cup body are tightened; if the outer cover is tightened in the opposite direction (counterclockwise when viewed from top to bottom), the block will move upward along the first inclined surface of the slot until it completely disengages the slot and then enters the next slot. This reciprocating process means that the outer cover is always "idling" and does not drive the inner cover to rotate together.

[0028] Furthermore, an eccentric wheel 32 is provided on the main shaft of the motor 31; a second spring 42 is provided on the side of the hook away from the eccentric wheel, and the hook and the eccentric wheel are in contact with each other. Figure 8 It can be seen that the top of the hook is provided with a hook head 419 for hooking into the hanging hole. When the eccentric wheel pushes the hook outward, the hook head releases from the hanging hole, allowing the flip cover to open. Conversely, if the eccentric wheel does not exert an outward force on the hook, after the flip cover is closed, the second spring pushes the hook inward, causing the hook head to hook into the hanging hole 130 of the flip cover, locking the flip cover.

[0029] Furthermore, the insertion rod 51 is mounted at the bottom of a rod holder 5. A third spring 52 is installed at the bottom of the rod holder, with the bottom of the third spring abutting against the inner cover. The top of the rod holder 5 abuts against the eccentric wheel 32. When the eccentric wheel presses downward on the rod holder, the holder and the rod move downward, allowing the rod to be inserted into the corresponding socket. When the eccentric wheel is not pressing downward on the rod holder, the holder returns to its original position under the action of the third spring.

[0030] Furthermore, the eccentric wheel 32 is an elliptical wheel. The advantage of this arrangement is that only one eccentric wheel can be used to control the position of the hook and the rod seat. For example, when the eccentric wheel presses the hook outward ( Figure 7 In the state shown), the eccentric wheel does not press the rod seat (i.e. the rod is not inserted into the socket of the inner cover), then the flip cover can be opened (to drink water through the straw), but the cup lid cannot be unscrewed. On the contrary, when the eccentric wheel presses the rod seat downward ( Figure 8 As shown in the figure), the rod is inserted into the socket of the inner cover, and the eccentric wheel does not press the hook. At this time, the flip cover cannot be opened, but the cup lid can be opened.

[0031] like Figure 9 and Figure 10 As shown, further, each of the slots is distributed in a ring shape. The clamping block can enter the adjacent slot from one slot in the circumferential direction to ensure that the outer cover can smoothly perform idle rotation.

[0032] Furthermore, the sockets are arranged in a circular pattern. This arrangement facilitates smooth insertion of the rod into the sockets. That is, when the rod seat is pressed by the eccentric wheel, even if the rod is not initially facing a particular socket, a slight rotation of the outer cover during use allows the rod to be inserted into the adjacent socket.

[0033] The outer cover is equipped with a mainboard, which is connected to at least one of a Bluetooth module, a fingerprint recognition module, a UWB module, and an NFC module. In practical applications, the motor can be controlled in a variety of ways. For example, the outer cover can be equipped with a mainboard, which is connected to at least one of a Bluetooth module, a fingerprint recognition module, a UWB module, and an NFC module. NFC refers to "Near Field Communication," and users can unlock the cup lid using products such as a mobile phone equipped with an NFC module or an NFC card. UWB refers to "Ultra Wide Band." For example, users can control the motor's rotation through a Bluetooth connection between a mobile phone and the cup lid, or through fingerprint recognition, or using products equipped with a UWB module or NFC module.

[0034] For ease of understanding, the structural principle of the children's cup is further explained below. For ease of explanation, the following example uses the cup body and inner cover connected by a right-hand thread (i.e., when viewed from top to bottom, the cup cover can be tightened by turning clockwise).

[0035] (1) When the eccentric wheel presses the hook but does not press the rod seat, the flip cover can be opened, the straw is exposed, and water can be drunk from the straw; when the rod is not inserted into the socket, turning the outer cover clockwise (viewed from top to bottom) can drive the inner cover to rotate together, thereby tightening the inner cover and the cup body. When the outer cover is turned counterclockwise, the inner cover will not move together.

[0036] (2) When the eccentric wheel presses the rod seat and does not press the hook, the flip cover cannot be opened; when the rod is inserted into the socket, turning the outer cover clockwise (viewed from top to bottom) can drive the inner cover to rotate together, thereby tightening the inner cover and the cup body. When the outer cover is turned counterclockwise, the inner cover will also rotate together, thereby opening the cup cover.

[0037] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and the utility model concept of the present invention, and all these changes or substitutions should fall within the scope of protection of the present invention.
