Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0041] To address the aforementioned problems, this application proposes improvements and innovations, including the following embodiments.

[0042] In one implementation, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 The first aspect of this application provides a fun drinking mechanism, including a base 1, a transparent cover 2, a rotating shaft 3, and a decorative part 4; wherein, the transparent cover 2 and the base 1 are fastened together to form a water storage cavity 100, the base 1 is constructed with a water inlet channel 101 communicating with the water storage cavity 100, and the transparent cover 2 is constructed with a water outlet channel 201 communicating with the water storage cavity 100; the rotating shaft 3 is rotatably disposed in the water storage cavity 100, and the two ends of the rotating shaft 3 are respectively rotatably inserted into the base 1 and the transparent cover 2, and one end of the rotating shaft 3 extends into the water inlet channel 101, and a water wheel 5 is fixedly disposed at the part of the rotating shaft 3 located in the water inlet channel 101, and the decorative part 4 is installed on the rotating shaft 3.

[0043] The transparent cover 2 is made of transparent material, allowing children or other drinkers to observe the rotation of the decorative element 4 through the transparent cover 2. Specifically, the decorative element 4 can be an item that can attract children's interest, such as a windmill or a doll. In this embodiment, the decorative element 4 is a windmill.

[0044] Thus, by fastening the transparent cover 2 to the base 1, the rotating shaft 3 is rotatably installed between the transparent cover 2 and the base 1, and a decorative piece 4 is set on the rotating shaft 3, so that the water inlet channel 101, the water storage cavity 100, and the water outlet channel 201 are connected to form a water flow channel. When liquid enters the water inlet channel 101 and flows through the water wheel 5, the water wheel 5 rotates under the impact of the liquid, and the water wheel 5 drives the rotating shaft 3 to rotate, so that the rotating shaft 3 drives the decorative piece 4 to rotate in the water storage cavity 100. The transparent cover 2 is made of transparent material, so children or other drinkers can observe the rotation of the decorative piece 4 through the transparent cover 2, thereby effectively increasing the fun of the water cup with this fun drinking mechanism. The instant feedback of the rotation of the decorative piece 4 when drinking water can attract children's interest, increase children's enjoyment of drinking water, and help improve children's enthusiasm for drinking water, so as to ensure that children drink enough water and protect children's physical health.

[0045] In some embodiments, the base 1 is provided with a mounting part 102, and the transparent cover 2 is provided with a positioning part 202. The two ends of the rotating shaft 3 are rotatably inserted into the mounting part 102 and the positioning part 202, respectively. The mounting part 102 and the positioning part 202 are used to constrain the axial position and radial position of the rotating shaft 3. Thus, by limiting the rotating shaft 3 through the mounting part 102 and the positioning part 202, axial movement or radial displacement of the rotating shaft 3 can be avoided, and the stable operation of the rotating shaft 3 can be ensured.

[0046] Furthermore, in some embodiments, the mounting part 102 is disposed inside the water inlet end of the water inlet channel 101, the mounting part 102 is provided with an insertion hole 103, the positioning part 202 is provided with a slot 203, the end of the slot 203 opposite to the rotating shaft 3 is closed, the slot 203, the insertion hole 103 and the water inlet channel 101 are coaxially arranged, the two ends of the rotating shaft 3 are respectively rotatably inserted into the insertion hole 103 and the slot 203, the water wheel 5 is disposed near the mounting part 102, and the upper end of the rotating shaft 3 is just not in contact with the top of the slot 203.

[0047] Thus, through the axial limiting effect of the mounting part 102 on the water wheel 5 and the axial limiting effect of the top of the slot 203 of the positioning part 202 on the rotating shaft 3, the rotating shaft 3 can be axially positioned, thereby preventing the rotating shaft 3 from axially moving within the water storage cavity 100. Through the radial limiting effect of the insertion hole 103 on the mounting part 102 and the slot 203 on the positioning part 202 on the rotating shaft 3, the rotating shaft 3 can be radially positioned, thereby preventing the rotating shaft 3 from radially shifting within the water storage cavity 100. This allows the rotating shaft 3 to remain coaxial with the water inlet channel 101 during the drinking process, and allows the rotating shaft 3 to rotate smoothly when the water wheel 5 is impacted by the liquid entering the water inlet channel 101, ensuring that the rotating shaft 3 drives the decorative part 4 to operate smoothly. This allows the decorative part 4 to attract children's interest while avoiding frightening children due to movement.

[0048] In some embodiments, the mounting part 102 has a water inlet hole 104 communicating with the water inlet channel 101, and the positioning part 202 has a water outlet hole 204 communicating with the water outlet channel 201. Thus, while the mounting part 102 and the positioning part 202 are used to install and position the rotating shaft 3, the water inlet channel 101 can be connected to a water source through the water inlet hole 104, and the water storage chamber 100 and the water outlet channel 201 can be connected to the outside through the water outlet hole 204, allowing liquid to flow smoothly through the playful drinking mechanism for drinking.

[0049] In some embodiments, a sucking tube 14 is detachably and fixedly embedded in the water outlet channel 201 of the transparent cover 2. The sucking tube 14 is connected to the water outlet channel 201, and a sleeve 15 is fitted over the outer end of the sucking tube 14. This makes it convenient for children to drink water through the sucking tube 14. At the same time, when not drinking water, the opening of the sucking tube 14 can be closed by the sleeve 15 to prevent debris from entering the playful drinking mechanism and the inside of the water cup and causing contamination.

[0050] In some embodiments, the rotating shaft 3 has a radially protruding fixed section 301 in the middle. The fixed section 301, near the waterwheel 5, has a radially protruding positioning step 302. The fixed section 301, away from the positioning step 302, has a transition section 303. The transition section 303 is a tapered structure that gradually narrows away from the fixed section. The decorative piece 4 is fixedly fitted onto the fixed section 301. Thus, the decorative piece 4 is made of a deformable material such as silicone. When the decorative piece 4 is installed onto the rotating shaft 3, it can be pressed onto the fixed section 301 under the guidance of the transition section 303, resulting in an interference fit between the decorative piece 4 and the fixed section 301. This achieves a fixed installation of the decorative piece 4 onto the rotating shaft 3. The positioning step 302 also provides a reference and limit for the installation position of the decorative piece 4 on the rotating shaft 3.

[0051] In some embodiments, the water wheel 5 includes an axle 501 and baffles 502. The axle 501 is fixedly mounted on the rotating shaft 3. Thus, when installing the rotating shaft 3, the mounting part 102 can limit the axle 501, thereby achieving axial limiting of the rotating shaft 3. Two baffles 502 are provided on the outer wall of the axle 501. The baffles 502 are spirally arranged through the axle 501, with the two baffles rotating in the same direction and staggered, forming a double-helix structure. In this way, when drinking water, the liquid entering the water inlet channel 101 can form an efficient and uniform impact on the water wheel 5, which is beneficial to increasing the rotational speed of the rotating shaft 3, effectively improving the aesthetics of the decorative part 4, and also improving the rotational stability of the rotating shaft 3. The rotating shaft 3 and the water wheel 5 can adopt a split and detachable structure or an integrated molding structure according to requirements or production conditions. In this embodiment, the rotating shaft 3 and the water wheel 5 are integrally molded, which is easy to assemble, has high structural strength, and a long service life.

[0052] In some embodiments, a sealing ring 6 is provided at the connection between the transparent cover 2 and the base 1. The lower end of the transparent cover 2 has three first notches 205 arranged in an array. Each first notch 205 contains a first positioning spring block 206. The base 1 has a first slot 105 arranged in an array, corresponding one-to-one with the first positioning spring block 206. The first slot 105 has a first positioning ridge 106 that protrudes radially in the first slot 105.

[0053] Thus, when the transparent cover 2 is installed onto the base 1 from top to bottom, each of the first positioning springs 206 is placed in the corresponding first slot 105. When the transparent cover 2 is rotated counterclockwise, the first positioning springs 206 elastically deform to pass over the first positioning protrusion 106, so that the first slot 105 and the first positioning protrusion 106 limit the first positioning springs 206 in the axial and circumferential directions of the transparent cover 2. Thus, through the cooperation of the first slot 105 and the first positioning springs 206, the base 1 forms an axial positioning of the transparent cover 2, and through the cooperation of the first positioning protrusion 106 and the first positioning springs 206, the base 1 forms a circumferential positioning of the transparent cover 2. This prevents the transparent cover 2 from becoming loose in the axial or circumferential direction from affecting the sealing performance, effectively ensuring the sealing performance of the water storage cavity 100, thereby ensuring that the liquid can be smoothly drawn into the water storage cavity 100.

[0054] In one implementation, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Corresponding to the aforementioned embodiment of the fun drinking mechanism, this application also provides a cup lid, including the aforementioned fun drinking mechanism, and further including a fixing base 7 and a locking ring 8;

[0055] The locking ring 8 is fixedly embedded in the fixed base 7. The lower end of the base 1 has three second notches 107 arranged in an array. Each second notch 107 contains a second positioning spring block 108. The outer wall of the lower end of the base 1 has three positioning blocks 109 arranged in an array protruding outward. The inner wall of the locking ring 8 has a second slot 801 corresponding to the positioning block 109. The inner wall of the locking ring 8 has a second positioning protrusion 802 corresponding to the second positioning spring block 108 arranged radially. The fixed base 7 is fitted with a sealing ring 12.

[0056] When the base 1 is installed onto the locking ring 8 from top to bottom, each positioning block 109 is placed in the corresponding second slot 801. Rotating the base 1 clockwise causes the positioning blocks 109 to engage with the second slot 801, and the second positioning spring 108 to elastically deform and pass over the second positioning protrusion 802. This results in the second slot 801 limiting the positioning blocks 109 axially on the base 1, and the second slot 801 and the second positioning protrusion 802 limiting the second positioning spring 108 circumferentially on the base 1. Thus, the second slot 801... The locking ring 8 is axially positioned on the base 1 by the cooperation of the positioning block 109 and the second positioning spring block 108. The locking ring 8 is circumferentially positioned on the base 1 by the cooperation of the second positioning protrusion 802 and the second positioning spring block 108. This achieves a detachable fixed connection between the base 1 and the locking ring 8. The base 1 and the locking ring 8 are installed stably and are easy to disassemble and clean. In this embodiment, a sealing ring 12 is embedded on the fixing seat 7. Thus, when the cup lid is installed on the cup body 13 of the water cup, the cup mouth of the cup body 13 can be sealed by the sealing ring 12.

[0057] In some embodiments, the cup lid also includes a connecting tube 9, a straw 10, and a one-way air inlet valve 11; the connecting tube 9 is fixedly embedded in the middle of the fixed base 7, the water inlet channel 101 of the base 1 is detachably fixedly inserted into the upper part of the connecting tube 9, the outer wall of the water inlet channel 101 is sealed to the inner wall of the connecting tube 9, the straw 10 is detachably fixedly inserted into the lower part of the connecting tube 9, and the straw 10, the connecting tube 9, and the water inlet channel 101 are connected in sequence; thus, the straw 10, the connecting tube 9, the water inlet channel 101, the water storage cavity 100, the water outlet channel 201, and the sucking tube 14 are connected to form a water flow channel, thereby realizing the drinking action through the water flow channel, and driving the decorative part 4 to rotate in the water storage cavity 100 during the drinking process.

[0058] In this embodiment, the fixed base 7 is provided with an air inlet 701. The air inlet 701 is connected to the outside through the gap between the locking ring 8 and the base 1. The one-way air inlet valve 11 is fixedly installed on the fixed base 7 corresponding to the air inlet 701. In this way, when drinking water, when the water volume in the cup decreases and negative pressure is generated, air can enter the cup through the one-way air inlet valve 11 to ensure that the water in the cup can be continuously drawn out.

[0059] In one implementation, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 Corresponding to the aforementioned cup lid embodiment, this application also provides a water cup, including the aforementioned cup lid, and also including a cup body 13. The cup lid fixing seat 7 is detachably connected to the cup body 13 by threads, and the fixing seat 7 and the cup mouth of the cup body 13 are sealed by a sealing ring 12.

[0060] Finally, it should be noted that although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, all of which should be included within the protection scope of this application.
