Abstract
Description
Technical Field
[0001] The present invention relates to the field of cups, and particularly to a pressing water outlet type cup lid.
Background Art
[0002] Currently, even after exercise, the hearts of athletes are still in a high-load state. If a large amount of water is drunk at once, the blood volume will increase rapidly, the blood pumping pressure of the heart will rise sharply, which may lead to a feeling of chest compression, arrhythmia, and even heart failure. In contrast, by drinking water in small amounts and dividing it into multiple times, the body fluid balance can be gently adjusted and rapid fluctuations in blood volume can be avoided. However, currently widely used cups cannot accurately control the amount of water drunk each time, which may lead to safety problems.
Summary of the Invention
Problems to be Solved by the Invention
[0003] In order to solve the above problems, the present invention proposes a pressing water outlet type cup lid that solves the problem of not being able to accurately control the amount of water drunk each time when drinking water with a cup.
Means for Solving the Problems
[0004] Regarding the technical solution adopted by the present invention, the pressing water outlet type cup lid includes a case provided with a water outlet. A water supply channel, a water storage channel, and a water outlet channel are provided in the case. The water outlet is connected to the water outlet channel. In the water storage channel, a first check valve communicating with the water supply channel and a second check valve communicating with the water outlet channel are installed. A piston is slidably connected in the water storage channel. In the process of pulling the piston outwards, liquid can flow from the water supply channel into the water storage channel. In the process of pushing the piston inwards, liquid can flow from the water storage channel into the water outlet channel.
[0005] According to the above technical solution, when a user uses the device, pulling the piston outwards creates negative pressure inside the cup, opening the first check valve and allowing liquid to flow from the water supply channel into the water storage channel. Subsequently, the user pushes the piston inwards, opening the second check valve while keeping the first check valve closed, allowing the liquid in the water storage channel to flow into the second channel. This ensures that the user can drink a fixed amount of water each time, avoiding safety risks after exercise.
[0006] Furthermore, the system further includes an elastic member that connects the piston and the case.
[0007] According to the above technical solution, the elastic member allows the piston to automatically return to its original position each time it is pressed, thereby making it easy for the user to refill the water in multiple stages.
[0008] Furthermore, the piston comprises a rubber head that contacts the water reservoir channel in the circumferential direction, and a slide rod.
[0009] According to the above technical solution, the rubber head is in circumferential contact with the water storage channel, and when the piston is pressed, all the liquid in the water storage channel is discharged into the water outlet channel.
[0010] Furthermore, the case is provided with an escape opening, and the end of the slide rod is located outside the escape opening.
[0011] According to the above technical solution, the end of the slide rod is located outside the relief opening, thereby allowing the user to easily press the piston.
[0012] Furthermore, the axial extension direction of the piston is parallel to the axial extension directions of the first and second check valves.
[0013] According to the above technical solution, the pressing and pulling of the piston allows the liquid to easily pass through the first and second check valves, thereby reducing resistance.
[0014] Furthermore, the case is provided with a first mounting groove that fits the first check valve and a second mounting groove that fits the second check valve.
[0015] According to the above technical solution, the first check valve and the second check valve are stably mounted and no looseness occurs.
[0016] Furthermore, first contraction portions for restricting the first check valve are provided on both sides of the first mounting groove, and second contraction portions for restricting the second check valve are provided on both sides of the second mounting groove.
[0017] According to the above technical solution, the first and second contraction portions restrict the first and second check valves, respectively, thereby stabilizing the mounting of the first and second check valves.
[0018] Furthermore, a limiting plate is installed inside the case, the slide rod is slidably connected to the limiting plate, and when the rubber head contacts the limiting plate, the piston is pulled outward to its limit distance.
[0019] According to the above technical solution, the limiting plate prevents the piston from detaching from the case by restricting the rubber head.

[0027] When the user uses the device, pulling the piston 4 outwards creates negative pressure inside the cup, opening the first check valve 2, and liquid flows from the water supply channel 102 into the water storage channel 103. Then, the user pushes the piston 4 inwards, opening the second check valve 3 while keeping the first check valve 2 closed, and the liquid in the water storage channel 103 flows into the second channel. This allows the user to drink a fixed amount of water each time, avoiding safety risks after exercise.
[0028] Referring to Figure 2, the case further includes an elastic member 5 that connects the piston 4 and the case 1.
[0029] The elastic member 5 allows the piston 4 to automatically return to its original position each time it is pressed, making it easy for the user to refill the water in multiple stages.
[0030] Preferably, the elastic member 5 is a spring.
[0031] Referring to Figure 2, the piston 4 comprises a rubber head 401 that contacts the water reservoir channel 103 in the circumferential direction, and a slide rod 402.
[0032] The rubber head 401 is in circumferential contact with the water storage channel 103, and when the piston 4 is pressed, all the liquid in the water storage channel 103 is discharged into the water outlet channel 104.
[0033] Referring to Figures 1 and 2, a relief opening 105 is provided in case 1, and the end of the slide rod 402 is located outside the relief opening 105.
[0034] The end of the slide rod 402 is located outside the relief opening 105, thereby allowing the user to easily press the piston 4.
[0035] Referring to Figure 2, the axial extension direction of the piston 4 is parallel to the axial extension directions of the first check valve 2 and the second check valve 3.
[0036] The pressing and pulling of piston 4 allows the liquid to easily pass through the first check valve 2 and the second check valve 3, thereby reducing resistance.
