As people's living standards continue to improve, consumers are very concerned about the safety of water cups. After strenuous exercise, people usually feel dry mouth and tongue, and they need to drink a proper amount of water. If people absorb a lot of water in a short period of time after strenuous exercise, the water will enter the human body and be absorbed by the gastrointestinal tract, which will make the blood thinner and increase blood volume. At the same time, the heart workload and myocardial oxygen consumption will also increase accordingly, thus affecting people's physical health.

[0003] In order to control the large amount of water absorbed in a short time after intense exercise, quantitative water cups have appeared on the market. Quantitative water cups can control the amount of water people drink and avoid the phenomenon of absorbing a large amount of water in a short time. However, the existing quantitative water cups usually have a quantitative cylinder in the cup body, and the water in the cup body is poured into the quantitative cylinder, and then the water in the quantitative cylinder is absorbed. This quantitative water cup has the problems of complex structure and inconvenience in use, and cannot meet the demand of slowly absorbing a small amount of water. Summary of the invention

[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0021] It should be understood that the directions or positional relationships indicated by terms such as "upper", "lower", "left", "right", "front", "back", and "middle" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation of the present invention.

[0022] like Figures 1 to 3 As shown, a quantitative cup cover provided by an embodiment of the present invention comprises an elastic member, a drinking straw assembly 2 and a cup cover 3; the cup cover 3 comprises a tube body 31 and a cover body 32 connected to the tube body 31, the tube body 31 is provided with a first through hole 311, and the side wall of the tube body 31 is provided with a first side opening 312 communicating with the first through hole 311; it can be understood that the tube body 31 and the cover body 32 are an integrally formed part, a part of the tube body 31 is located above the cover body 32, and another part of the tube body 31 is located below the cover body 32; the top of the tube body 31 is an opening, and the bottom of the tube body 31 is blocked by the drinking straw assembly 2.

[0023] The drinking straw assembly 2 is provided with a drinking hole 21 and a second side opening 22 connected to the drinking hole 21; the drinking straw assembly 2 is slidably inserted in the first through hole 311, and the elastic member is sleeved on the drinking straw assembly 2 and located in the drinking hole 21; it can be understood that the drinking hole 21 is arranged along the axial direction of the drinking straw assembly 2, and the second side opening 22 is arranged on the side wall of the drinking straw assembly 2; the elastic member includes but is not limited to a spring, etc.

[0024] The drinking straw assembly 2 slides in the first through hole 311 so that the first side opening 312 is connected to the second side opening 22, or the tube body 31 blocks the second side opening 22, and the drinking straw assembly 2 blocks the first side opening 312 (the tube body 31 and the drinking straw assembly 2 are in a mutually blocked state due to misalignment).

[0025] Specifically, Figure 1As shown, when the drinking straw assembly 2 is not subjected to a pulling force, the rebound force of the elastic member causes the drinking straw assembly 2 to move downward in the first through hole 311 until the side wall of the tube body 31 blocks the second side opening 22, and the drinking straw assembly 2 blocks the first side opening 312. Thus, the drinking hole 21 is not connected to the accommodating space of the cup body, that is, the water in the cup body will not flow out through the drinking hole 21.

[0026] like Figure 2 and Figure 3 As shown, the user needs to bite the top of the drinking straw assembly 2 and pull the drinking straw assembly 2 upward, and the drinking straw assembly 2 moves upward in the first through hole 311 until the second side opening 22 is connected to the first side opening 312. At this time, the drinking hole 21 is connected to the accommodation space of the cup body through the second side opening 22 and the first side opening 312 in sequence. When the user drinks water through the drinking hole 21 (under normal conditions, the user tilts the water cup and pours the liquid in the cup body into the mouth through the drinking hole 21), the mouth will automatically release the drinking straw assembly 2. Due to the rebound force of the elastic member, the drinking straw assembly 2 gradually moves downward in the first through hole 311 until the side wall of the tube body 31 blocks the second side opening 22. When the drinking straw assembly 2 moves from the open state to the blocked state in the first through hole 311, the user can drink a fixed amount of liquid through the drinking straw assembly 2 to avoid the phenomenon of "explosive drinking" caused by the drinking straw assembly 2 being in the on state all the time. In the present invention, the quantitative cup cover can control the amount of water a user drinks, and has a simple structure and low manufacturing cost.

[0027] In one embodiment, if Figure 1 , Figure 4 as well as Figure 5 As shown, the drinking straw assembly 2 includes an outer tube 23 provided with an inner hole 2321 and an inner tube 24 inserted in the inner hole 2321, the drinking hole 21 is arranged on the inner tube 24, and the second side opening 22 is arranged on the side walls of the inner tube 24 and the outer tube 23 (that is, the second side opening 22 is provided on the side walls of the inner tube 24 and the outer tube 23); it can be understood that the bottom of the inner tube 24 is inserted in the inner hole 2321 of the outer tube 23, the top of the inner tube 24 extends out from the first through hole 311, and the outer tube 23 can play a role in blocking the bottom of the drinking hole 21.

[0028] A stopper 313 is provided on the inner wall of the first through hole 311, the elastic member is sleeved on the inner tube 24, and the opposite ends of the elastic member are respectively in contact with the stopper 313 and the outer tube 23. It can be understood that the stopper 313 is provided at the top of the tube body 31 and extends toward the middle of the first through hole 311; the elastic member is compressed between the stopper 313 and the top of the outer tube 23.

[0029] In this embodiment, the drinking straw assembly 2 includes a combination design of an inner tube 24 and an outer tube 23 , which facilitates the assembly of the drinking straw assembly 2 and has a low manufacturing cost.

[0030] In one embodiment, if Figure 1 , Figure 4 as well as Figure 5 As shown, the drinking straw assembly 2 further includes a sealing sleeve 25 sleeved on the outer tube 23, and the side of the sealing sleeve 25 facing away from the outer tube 23 abuts against the inner wall of the first through hole 311. It can be understood that the sealing sleeve 25 can be made of materials such as silicone, and the sealing sleeve 25 can not only seal the gap between the outer tube 23 and the tube body 31, but also increase the friction between the outer tube 23 and the tube body 31. When the user's mouth releases the outer tube 23, the drinking straw assembly 2 slowly moves down in the first through hole 311, and the user can drink enough water through the drinking straw assembly 2, avoiding the accident of drinking too little water due to the drinking straw assembly 2 moving too fast in the first through hole 311.

[0031] In one embodiment, if Figure 1 and Figure 3 As shown, the outer tube 23 is provided with a limiting flange 231, and the elastic member and the sealing sleeve 25 are respectively abutted against the opposite ends of the limiting flange 231; it can be understood that the limiting flange 231 is arranged at the top of the outer tube 23; the end of the elastic member away from the blocking portion 313 is abutted against the upper surface of the limiting flange 231, and the top of the sealing sleeve 25 is abutted against the bottom surface of the limiting flange 231, thereby ensuring the stability of the elastic member installed in the first through hole 311, and ensuring the stability of the sealing sleeve 25 sleeved on the outer tube 23.

It can be understood that the limiting convex portion 314 is located below the blocking portion 313 .

[0033] Specifically, when the user bites the top of the inner tube 24 with his mouth and pulls the drinking straw assembly 2 upward, the drinking straw assembly 2 slides in the first through hole 311 until the limiting flange 231 abuts against the limiting convex portion 314. At this time, the drinking straw assembly 2 cannot continue to move upward in the first through hole 311, so that the limiting convex portion 314 and the limiting flange 231 abutting against each other can limit the upward movement of the drinking straw assembly 2 in the first through hole 311, thereby preventing the drinking straw assembly 2 from moving too much upward in the first through hole 311 and causing the tube body 31 to block the second side opening 22. In this embodiment, the design of the limiting convex portion 314 can control the drinking straw assembly 2 to move to a fully conductive state in the first through hole 311.

[0034] In one embodiment, if Figure 1 and Figure 4 As shown, the drinking straw assembly 2 includes a bite sleeve 26 sleeved on one end of the inner tube 24 away from the outer tube 23.
