Technical Field
[0001] This utility model relates to the field of water cups, specifically to a water cup with a straw. Background Technology
[0002] Water cups, as a tool used for fetching, drinking, and carrying water, are ubiquitous in various aspects of life. They need to be able to store hot water, be easy to carry, have anti-scalding properties, prevent choking when drinking, and be easy to clean. Furthermore, water cups should save space when placed in a room and serve a decorative purpose when not in use, among other uses. Therefore, there is a growing demand for innovative features in water cups, including anti-scalding, easy-to-clean, anti-choking, and decorative functions.
[0003] Common water cups are only used for filling and drinking water, with relatively simple functions that only fulfill the basic purpose of a water cup. Some water cups simply add anti-scalding features and a lid, with the ultimate goal of minimizing overall cost to maximize sales. The wide openings of most water cups cause water to rush into the user's mouth, easily leading to choking. For users who need to drink hot water quickly before it has cooled completely, or for those with oral, esophageal, or tracheal issues who need to be mindful of their drinking speed, large openings are insufficient. Furthermore, in small homes, water cups used solely for drinking take up valuable storage space. These factors significantly impact user satisfaction with the water cup experience.
[0004] Currently, most water cups are made of single-layer rolled paper, while some are made of glass or single-layer stainless steel. These cups are prone to scalding hands when filled with boiling water, causing choking when drinking, and easily overflowing when overfilled. Some cups simply have a heat-resistant mat, while glass cups are more easily broken. To address the choking problem, some cups incorporate simple straws, but these straws are often made of plastic and are only for single use. Some use stainless steel straws, but cleaning the inside of the straw is relatively difficult, thus adding more problems. Furthermore, in small living spaces, water cups are often only used for drinking, but storing them takes up space. If there are many family members, the space occupied by the water cups increases, often leading to some people disliking using water cups or reducing their water intake. The disadvantages of the above-mentioned existing technologies are: 1. The water cup has a single-layer structure and does not have anti-scalding function, and it is easy to spill water or choke on water when using it; 2. For water cups with straws, the straws are not easy to clean, disposable straws lead to waste and cannot be reused, ultimately wasting resources and affecting the environment; 3. The water cup has only a single function and takes up living space.
[0005] Therefore, to solve the above problems, providing a water cup with a straw is the subject of this invention. It is necessary to add a straw function to the water cup, allowing the user to adjust the amount of water flowing out by speaking through the mouth or using suction. In addition, the water cup should also have spill-proof, scald-proof, and portable functions. Using the water cup as a decorative item or for other purposes can enhance the user's appreciation of it, thereby improving the user's quality of life experience. Furthermore, utilizing reusable high-temperature sterilization and easy cleaning improves the practicality of the water cup and reduces waste. Summary of the Invention
[0006] This utility model provides a water cup with a straw, aiming to solve the problems of water cups lacking spill prevention, scalding prevention, and easy choking when drinking water. It also adds a water cup and straw to make it easy to clean, disinfect, and reuse, and to avoid choking when drinking water with a straw. In addition, it solves the problem of water cups having only a single function, enriching the decoration and practicality of water cups in living spaces to achieve multi-functionality and reduce waste.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a water cup with a straw, comprising a water cup and a straw; the water cup includes a cup base, a cup ring sleeve, a cup body, a diaphragm and a cup lid; the straw includes a tube body, a flexible straw nozzle and a ball.
[0008] The water cup includes a base, a body, a ring, a diaphragm, and a lid. The base is a flexible structure, installed at the bottom of the body via an interference fit. The ring consists of multiple interconnected M-shaped arches forming a circular ring, with its inner diameter smaller than the outer diameter of the body. The ring is located near the upper part of the body and has a circular handle for easy lifting. The lid has an arc-shaped buckle on one side to engage with the handle. The lid has at least two upright, ear-shaped structures facing forward, with two small holes for securing the diaphragm. Two small, arc-shaped protrusions are located beside these holes. Further forward is a slanted straw hole at the edge of the lid. The lid has a raised, head-like top. A slanted protrusion runs through the bottom edge of the straw hole. Below the head-like protrusion on the top of the lid are two tooth-like structures. The overall shape of the lid resembles a rabbit. A lid retaining ring and a lid clip are designed on the bottom edge of the lid. The lid is inverted and placed on the shoulder wall of the cup body using these features. The retaining ring and the cup body have an interference fit. One end of the diaphragm has two cylindrical protrusions, and one side has a circular diaphragm plane. The two cylindrical protrusions are used to install the diaphragm into two small holes on the lid, aligning the diaphragm plane with the straw hole. The diaphragm plane is parallel to the inner surface of the lid. The slanted protrusion at the straw hole forms an angle with the lid surface, ensuring a tight fit between the diaphragm and the slanted protrusion. The cup body is a water-holding structure made of stainless steel for easy reuse during high-temperature sterilization. The rim of the cup body has a shoulder wall perpendicular to the cup wall.
[0009] The straw includes a tube body, a flexible tube nozzle, and a ball. The tube body has an open opening in its thin wall, forming a C-shaped semi-enclosed circular tube. The tube body is made of stainless steel that can be sterilized at high temperatures and is reusable. One end of the flexible tube nozzle is a C-shaped semi-enclosed circular flexible tube, and the other side of the C-shaped tube has a flexible tube limiting wall. The front of the flexible tube nozzle has multiple water inlet holes communicating with the inner hole of the tube. One end of the flexible tube nozzle has a nozzle head with a raised circular tube. The nozzle head has several water outlet holes that communicate with the inner hole of the tube. The flexible tube nozzle is made of food-grade silicone material, which can meet the requirements of high-temperature sterilization. The C-shaped tube body and the C-shaped flexible tube at one end of the flexible tube nozzle are assembled to form a closed circular tube body. The ball is a circular stainless steel ball, which is installed in the inner cavity of the convex tube of the flexible tube nozzle and can move flexibly inside the inner cavity of the tube. The ball can completely fit the side walls of the tube holes at both ends of the flexible tube nozzle.
[0010] The relevant content in the above technical solution is explained as follows.
[0011] 1. In the above solution, the cup base is a flexible structure assembled with the cup body by an interference fit. This assembly facilitates the disassembly of the cup base and the cleaning of the cup body. The flexible structure of the cup base makes it easier for the cup base to hit the ground first during the drop of the cup, and the cup base will rebound to buffer the cup and achieve shock absorption and protection. A structure is provided on one side of the cup base to be connected to the cup ring sleeve.
[0012] 2. In the above solution, the cup ring sleeve is a circular ring formed by multiple interconnected M-shaped arches. At least one handle ring is provided on one side of the cup ring sleeve, with a handle ring top hole at the top. Cup ring sleeve limiting ribs are provided on the M-shaped arches of the cup ring sleeve. The inner diameter of the cup ring sleeve is designed to be smaller than the outer diameter of the cup body. The cup ring sleeve and the cup body are assembled with an interference fit. The cup ring sleeve is positioned against the shoulder wall of the cup body through the limiting ribs. Furthermore, the interference fit allows the cup ring sleeve to firmly enclose the cup body. The M-shaped arch structure reduces the contact area between the cup ring sleeve and the outer surface of the cup body, thereby effectively reducing the surface temperature transferred from the cup body to the cup ring sleeve when hot water is poured into the cup, thus achieving a scalding prevention effect.
[0013] 3. In the above solution, an arc-shaped buckle is provided on one side of the cup lid, which is fastened to the handle ring of the cup ring sleeve by means of a buckle with the top hole of the handle ring; the top of the cup lid has two raised ears, and there is an arc-shaped small protrusion in front of the ears. The two raised ears on the top of the cup lid and the two arc-shaped small protrusions in front of the ears serve as limiting points, and the two raised ears can support some lightweight objects placed at an angle; the bottom of the cup lid has a cup lid limiting ring, and the cup... The lid retaining ring and the cup body are sealed by an interference fit. Several lid buckles are provided on the edge of the lid retaining ring. The lid buckles are interlocked with the cup body's rim and shoulder wall to prevent liquid from spilling when the cup is tilted. After the lid is fastened, two downward-facing tooth-like structures on the front of the lid and the side retaining protrusions on the front of the cup ring can hold the straw placed there. At the same time, the lid can be opened by using the tooth-like structures to lift the lid outward and disengage the lid buckles from the cup body's rim and shoulder wall.
[0014] 4. In the above solution, one end of the diaphragm is provided with a cylindrical protrusion, and the other end is a flat sealing surface. The diaphragm is installed at the small round hole of the cup lid through two cylindrical protrusions. The sealing surface of the diaphragm is parallel to the inner surface of the cup lid. The inclined protrusion of the straw hole forms a certain angle with the surface of the cup lid. At this time, the squeezing force generated by the deformation of the sealing surface of the diaphragm and the fixed position makes the sealing surface of the diaphragm fit tightly with the inclined protrusion of the straw hole. This can effectively prevent the liquid in the cup from flowing out of the straw hole, and at the same time prevent external dust or foreign objects from entering the cup through the straw hole. When the straw is inserted into the straw hole on the cup lid, the diaphragm is turned to the other side by pushing it open, so that the straw can be smoothly inserted into the cup body.
[0015] 5. In the above solution, the straw is formed by inserting a C-shaped tube body into the outside of a C-shaped flexible straw nozzle. The C-shaped flexible straw nozzle and the two sides of the C-shaped tube body support each other. The C-shaped flexible straw nozzle has two short circular rings to prevent it from collapsing under pressure on one side. Furthermore, the two parts are designed with an interference fit to prevent liquid leakage from the gaps in the straw wall after assembly. The assembly process of the tube body and the flexible straw nozzle involves mutual restraint between the open end of the tube body and the flexible straw retaining wall. When cleaning the inside of the straw... When the C-shaped flexible straw is pulled out, two small circular rings on the flexible straw can carry out the dirt deposited inside the C-shaped tube. At the same time, the tube and the flexible straw are C-shaped semi-enclosed, meaning the tube is open, which makes it easy to see the cleaning status of the tube wall from the side, which is conducive to cleaning the deposits inside the straw. When the straw is inserted into the lid of the cup, the air pressure generated inside the cup when drinking water through the straw is achieved by using the straw gap formed by the C-shaped tube inserted into the edge of the C-shaped flexible straw to make the air pressure the same as the air pressure inside and outside the cup. This makes it easier to drink the liquid from the cup through the straw.
[0016] 6. In the above solution, the front end of the C-shaped tube end of the flexible tube nozzle is provided with at least a few water inlet holes. The number of small holes designed for the water inlet holes is conducive to preventing foreign objects from entering the tube and causing blockage of the straw when the straw is inserted into a beverage containing tea leaves or other steeping substances. At least a few water outlet holes are provided at one end of the flexible tube nozzle and are connected to the inner hole of the straw.
[0017] 7. In the above solution, a ball is provided inside the convex-shaped tube of the flexible straw nozzle. The ball can move within the tube cavity under its own weight. When a large suction force is applied through the straw, the ball will slide towards the water outlet of the flexible straw nozzle. Eventually, the ball will press against the inner wall of several water outlets of the flexible straw nozzle to achieve a flow interception effect. When air or other substances are blown into the flexible straw nozzle, the ball will slide down to the other side of the flexible straw nozzle under the force, and at the same time, the ball will block the inner wall of the tube hole, preventing the blown air or other substances from flowing into the water cup. By squeezing the outer wall of the convex-shaped tube, the flexible straw nozzle can effectively control the flow rate of the straw by reducing the gap between the inner cavity of the convex-shaped tube and the ball. This design effectively prevents choking problems caused by drinking water with a straw.
[0018] 8. In the above design, the overall external shape of the water cup resembles a rabbit, and the ear part can also support objects placed at an angle. Through these functions, the water cup can be used as a decorative item in life to fully realize the multi-functionality of the water cup.
[0019] The working principle and advantages of this utility model are as follows.
[0020] 1. The base of the water cup is made of a soft structure, which effectively prevents the water cup from breaking during a drop. At the same time, the base is assembled with the cup body by interference fit, so that the base will not detach naturally. In addition, the soft material makes it easy to disassemble the base and the cup body and to clean the cup body.
[0021] 2. The cup ring sleeve is composed of multiple interconnected M-shaped arches that fit together with the cup body via an interference fit. The M-shaped arches reduce the contact area between the cup ring sleeve and the outer surface of the cup body, thereby effectively reducing the surface temperature transferred from the cup body to the cup ring sleeve when hot water is poured into the cup, thus achieving a scalding prevention effect.
[0022] 3. The cup lid uses a raised ear shape to support the tilted object, thus serving as a support. At the same time, when the cup body is fastened, the lid uses a tooth-like structure to fix the external straw. The tooth-like structure also makes it easy to open the cup lid, achieving a user-friendly design. The cup lid and cup body are sealed together by interference fit and snap fastener, so that no liquid will spill when the cup is tilted.
[0023] 4. The straw hole in the lid has a membrane that effectively prevents liquid from flowing out when the cup is tilted or dropped. It also prevents foreign objects from entering the cup through the hole. The membrane can also be easily opened when inserting a straw.
[0024] 5. The straw is formed by inserting a C-shaped tube body into the outside of a C-shaped flexible straw mouthpiece. When cleaning the straw, the flexible straw mouthpiece will remove dirt from the C-shaped tube body when it is pulled out. The two C-shaped tubes and the flexible straw mouthpiece are easier to rinse with water. The materials used for the tube body and the flexible straw mouthpiece are conducive to the high-temperature sterilization of the straw.
[0025] 6. The flow rate of liquid drawn out by the straw is controlled by the ball inside the convex tube of the flexible straw nozzle. By squeezing the convex tube and reducing the amount drawn out, the flow of liquid in the tube can be stopped if the suction is too strong. These two operations can effectively prevent the risk of choking. In addition, when spitting water or blowing a large amount of air into the cup through the flexible straw nozzle, the ball also has the function of intercepting the flow, effectively preventing the water cup from being contaminated.
[0026] 7. The water inlet of the straw consists of several small holes connected to the inner tube of the straw. When using the straw, the small holes can prevent large foreign objects in the cup from being sucked into the tube and causing blockage.
[0027] 8. The overall shape of the water cup resembles a rabbit, making it a decorative item in daily life. In addition, the handle on the lid can be used as a support, realizing the multi-functionality of the water cup. Attached Figure Description

[0038] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0039] Example 1: See Appendix Figure 1-6 As shown, a water cup with a straw includes a cup 1 and a straw 31. The cup 1 includes a cup base 2, a cup body 3, a cup ring 4, a diaphragm 18, and a cup lid 7. The cup base 2 is a flexible structure, and the cup base 2 is assembled to the bottom of the cup body 3 by an interference fit, thus protecting the cup 1.
[0040] The cup ring sleeve 4 is a circular ring formed by connecting multiple m-shaped arches 26. At least one handle ring 5 is provided on one side of the cup ring sleeve 4, and a handle ring top hole 24 is provided on the top of the handle ring 5. The cup ring sleeve 4 has cup ring sleeve limiting ribs 25 on the m-shaped arches 26. The inner diameter of the cup ring sleeve 4 is designed to be smaller than the outer diameter of the cup body 3. The cup ring sleeve 4 and the cup body 3 are combined with an interference fit. The cup ring sleeve limiting ribs 25 fit and limit the cup body rim shoulder wall 19. In addition, the interference fit can make the cup ring sleeve 4 firmly wrap the cup body 3. The m-shaped arch structure 26 reduces the contact area between the cup ring sleeve 4 and the outer surface of the cup body 3, thereby effectively reducing the surface temperature transferred from the cup body 3 to the cup ring sleeve 4 when hot water is poured into the cup 1, so as to achieve the anti-scalding effect.
[0041] The cup lid 7 has an arc-shaped buckle 6 on one side, which is fastened to the handle ring 5 of the cup ring sleeve 4 by means of a buckle 6 and a handle ring top hole 24. The top of the cup lid 7 has two raised ears 8, and the front of the ears 8 has an arc-shaped small protrusion 9. The two raised ears 8 on the top of the cup lid 7 and the two arc-shaped small protrusions 9 in front of the ears 8 serve as limiting points, and the two raised ears 8 can support some light-weight tilted objects 23. The bottom of the cup lid 7 has a cup lid limiting ring 22, and the cup lid limiting ring 22 is connected to the cup body 3 by interference fit. The cup lid is sealed, and the edge of the cup lid limiting ring 22 has several cup lid buckles 20. The cup lid buckles 20 are fastened together with the cup body shoulder wall 19 to prevent liquid from spilling when the cup 1 is tilted. After the cup lid 7 is fastened, the two downward tooth-like structures 12 on the front of the cup lid and the side limiting protrusions 21 on the front of the cup ring sleeve 4 can be used to hold the straw 31 placed there. At the same time, the cup lid 7 can be opened by using the tooth-like structures 12 to lift the cup lid 7 outward to disengage the cup lid buckles 20 from the cup body shoulder wall 19. This reflects the humanized design of the cup lid 7.
[0042] See appendix Figure 6 As shown, the diaphragm 18 has a cylindrical protrusion 27 at one end and a flat sealing surface 28 at the other end. The diaphragm 18 is installed at the small round hole 31 of the cup lid 7 through the two cylindrical protrusions 27. The sealing surface 28 of the diaphragm 18 is parallel to the inner surface of the cup lid 7. The inclined protrusion 30 of the straw hole 29 forms a certain angle with the cup lid surface, so that the diaphragm 18 and the inclined protrusion 30 of the straw hole 29 fit tightly together. This can effectively prevent the liquid in the cup 1 from flowing out of the straw hole 29, and at the same time prevent external dust or foreign objects from entering the cup 1 through the straw hole 29. When the straw 32 is inserted into the straw hole 29 on the cup lid 7, the diaphragm 18 is turned to the other side by pushing it open, and the straw 32 can be smoothly inserted into the cup body 3.
[0043] The straw 32 is formed by inserting a C-shaped tube body 34 into the outside of a C-shaped flexible straw nozzle 35. The C-shaped flexible straw nozzle 35 and the two sides of the C-shaped tube body 34 support each other. The C-shaped flexible straw nozzle has two small circular rings 39 to prevent it from collapsing under pressure on one side. The two parts are designed with an interference fit to prevent liquid leakage from the straw gap 36 after assembly. The tube body 34 and flexible straw nozzle 35 are assembled by mutual restraint between the tube body's open opening 38 and the flexible straw limiting wall 40. When cleaning the inside of the straw 32, the two small circular rings 39 on the flexible straw nozzle 35 are visible when pulled out. It can remove dirt deposited inside the C-shaped tube 34. At the same time, the tube 34 and the flexible tube 35 are designed in a C-shaped semi-enclosed shape, which facilitates cleaning the deposits inside the straw. When the straw 32 is inserted into the lid 7 of the water cup 1, the air pressure generated inside the cup when water is sucked out through the straw 32 is made the same as the air pressure outside the water cup by using the straw gap 36 formed by the C-shaped tube 34 inserted into the edge of the C-shaped flexible tube 35. That is, when the lid 7 is closed and the cup body 3 is inserted, the straw 32 is connected to the inside and outside of the cup by using the straw gap 36. The front end of the C-shaped flexible tube 35 of the flexible tube 10 is provided with at least a few water inlet holes 33, and the other end of the flexible tube 35 is provided with at least a few water outlet holes 37 that are connected to the inner hole 41 of the straw 32.
[0044] The flexible straw nozzle 10 has a ball 14 inside the protruding tube 11. The ball 14 can move within the inner cavity 13 of the protruding tube 11 under its own weight. When a large suction force is applied through the straw 32, the ball 14 will slide towards the water outlet 37 of the flexible straw nozzle 10. Eventually, the ball 14 will press against the inner wall 17 of several water outlets of the flexible straw nozzle 10 to achieve a flow interception effect. When air or other substances are blown into the straw 32 through the flexible straw nozzle 10, the ball 14 will slide down to the other side of the flexible straw nozzle 10 under the force. At the same time, the ball will block the inner wall 16 of the tube, preventing the blown air or other substances from flowing into the water cup 1. By squeezing the outer wall of the protruding tube 11, the flexible straw nozzle 10 reduces the gap between the inner cavity 13 of the protruding tube 11 and the ball 14, which can effectively control the flow rate of the straw. This design of the straw 32 can effectively prevent the risk of choking.
[0045] Example 2: See Appendix Figure 2 , 7As shown in Figure 9, the rest is the same as in Embodiment 1, except that the ball 14 in the straw 32 is removed, the outer diameter of the protruding tube 11 is set to the shape of a concave tube 42, and the diameter of the inner cavity 13 of the tube is reduced to a concave inner cavity 43. When using the straw of Embodiment 2, the concave inner cavity 43 is reduced by squeezing the concave tube 42, and the flow rate can be reduced under the same suction force.
[0046] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the scope of protection of the claims of this utility model.

The C-shaped flexible straw nozzle and the two sides of the C-shaped tube body support each other. The C-shaped flexible straw nozzle has two short circular rings to prevent it from collapsing under pressure on one side. The two parts are interference fit, so there is no liquid leakage in the gap of the tube wall after the two parts are assembled. When cleaning the inside of the straw, the two short circular rings on the flexible straw nozzle can carry away the dirt deposited inside the C-shaped tube body when the flexible straw nozzle is pulled out. The C-shaped semi-enclosed design of the tube body and flexible straw nozzle facilitates the cleaning of the deposits inside the straw.
7. A water cup with a straw according to claim 1, characterized in that: The C-shaped tube end of the flexible tube nozzle has an inlet and an outlet end with several small holes connected to the inner tube hole of the tube. These small holes prevent the tube from being blocked when large foreign objects are sucked into the inner tube hole during the water suction process.
8. A water cup with a straw according to claim 1, 6, or 7, characterized in that: The bead is located inside the raised tube of the flexible straw mouthpiece. Using its own weight, the bead moves downwards within the raised tube. Under strong suction, the bead slides towards the mouthpiece's outlet, eventually blocking several small holes in the mouthpiece to prevent flow. When air or other substances are blown into the flexible straw mouthpiece, the bead slides to the other side of the mouthpiece under pressure, simultaneously blocking the small holes and preventing the blown-in air or other substances from flowing into the cup. By compressing the outer wall of the raised tube, the flexible straw mouthpiece effectively controls the flow rate, reducing the gap between the inner wall of the raised tube and the bead, thus preventing choking.
9. A water cup with a straw according to claim 7, characterized in that: The soft tube of the straw has no ball inside the convex tube. By changing the convex tube to a concave tube, the diameter of the inner cavity can be changed. When drinking water, the straw bites into this position to change the size of the inner cavity, which can also change the flow rate of water sucked by the straw.
