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

[0024] See also Figures 1 to 10 , the utility model provides a children's cup. The accompanying drawings are only used to explain the structural principles and are not proportional to the actual products. 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 in this article 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 in actual applications, children can be placed in different directions. The "multiple" or "several" mentioned in this article refers to an indefinite number, because the number of structures referred to is not an invention point, so it is not specifically limited.

[0025] The children's 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, and a ratchet mechanism is arranged between the inner cover and the outer cover; the inner cover is provided with a plurality of jacks 110, and 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 or withdraw from the jack; the flip cover is provided with a hanging hole 130 (such as Figure 6 As shown in FIG. 1 ), a hook 41 is provided on the outer cover, and the motor is used to drive the hook to connect or separate with the hanging hole. In practical applications, the children's cup is also provided with a straw 91, which is inserted into the cup body, and the top of the straw extends from the top of the outer cover.

[0026] The motor and battery are connected to the main board respectively. The outer cover is provided with a charging interface 129 (such as Figure 1 The ratchet mechanism is that when the plug rod is not inserted into the jack, the outer cover and the inner cover can only rotate synchronously in one direction (ie, they can only be tightened but not loosened), so the cup cover cannot be opened.

[0027] It can be observed from the accompanying drawings that in actual application, a baffle 81 is provided at the bottom of the inner cover, which completely blocks structures such as the ratchet and the pawl plate. This arrangement can ensure that the water in the cup body will not pass through the ratchet mechanism and flow into the interior of the cup cover.

[0028] See also Figure 4 and Figure 5Further, the ratchet mechanism includes a pawl disc 21 connected to the outer cover, and an inner tooth ratchet 23 provided on the inner cover, and the pawl disc is provided with at least one pawl 22. The advantage of this arrangement is that the ratchet and the inner cover are integrally formed, making the structure more compact.

[0029] like Figure 5 As shown (the perspective is obliquely downward), further, a radial groove 220 is provided on the pawl disk, and a first spring 24 is provided in each radial groove, and each pawl is inserted into the corresponding radial groove. The number of the above pawls is at least one, and preferably, two pawls are provided opposite to each other. Since the first spring is located in the radial groove, it will generate elastic force on the pawl, so that the pawl and the ratchet wheel are against each other and the pawl disk can only rotate in one direction.

[0030] See also Figure 6-8 Furthermore, an eccentric wheel 32 is arranged on the main shaft of the motor 31; a second spring 42 is arranged on the side of the hook away from the eccentric wheel, and the hook and the eccentric wheel are against each other. Figure 8 It can be observed that a hook head 419 is provided on the top of the hook for hooking the hanging hole. When the eccentric wheel pushes the hook outward, the hook head is released from the hook and the flip cover can be opened. On the contrary, 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 so that the hook head hooks the hanging hole 130 of the flip cover and the flip cover is locked.

[0031] Furthermore, the insertion rod 51 is arranged at the bottom of an insertion rod seat 5, and a third spring 52 is arranged at the bottom of the insertion rod seat, and the bottom of the third spring abuts against the inner cover; the top of the insertion rod seat 5 abuts against the eccentric wheel 32. When the eccentric wheel presses the insertion rod seat downward, the insertion rod seat and the insertion rod move downward so that the insertion rod is inserted into the corresponding insertion hole. When the eccentric wheel does not press the insertion rod seat downward, the insertion rod seat is reset upward under the action of the third spring.

[0032] 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 (that is, 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 In the state shown), the insertion rod is inserted into the insertion hole 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.

[0033] Furthermore, in order to facilitate the smooth insertion of the insertion rod into the insertion hole, the inner cover is provided with a plurality of insertion holes distributed in a ring shape (such as Fig. 9 and Fig.10That is, when the rod seat is pressed by the eccentric wheel, even if the rod is not facing a certain insertion hole in the initial state, the rod can be inserted into the adjacent insertion hole by slightly rotating the outer cover during use.

[0034] In actual applications, there can be many specific control methods for the motor. For example, the outer cover is provided with a mainboard connected to at least one of a Bluetooth module, a fingerprint recognition module, a UWB module and an NFC module. The above-mentioned NFC refers to "Near Field Communication". The user can unlock the cup cover through a mobile phone, an NFC card and other products equipped with an NFC module. The above-mentioned UWB refers to "Ultra Wide Band". For example, the user can control the rotation of the motor through a Bluetooth connection between the mobile phone and the cup cover, or control the rotation of the motor by fingerprint recognition, or use a product equipped with a UWB module or an NFC module to control the rotation of the motor.

[0035] For ease of understanding, the structural principle of the children's cup is further explained below. For ease of explanation, the following takes the cup body and the inner cover connected by a right-hand thread (ie, when viewed from top to bottom, the cup cover can be tightened by turning clockwise) as an example.

[0036] (1) When the eccentric wheel compresses the hook but does not compress 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 (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.

[0037] (2) When the eccentric wheel compresses the rod seat and does not compress 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.

[0038] 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 utility model, and all these changes or substitutions should fall within the protection scope of the utility model.
