Description

Technical Field

[0001] This invention relates to the field of anti-choking drinking control technology, specifically to an anti-choking drinking control method and device. Background Technology

[0002] Anti-choking drinking devices are specialized drinking appliances designed for people with weak swallowing abilities. They are widely used in home daily care, elderly care and rehabilitation institutions, pediatric medical care, rehabilitation centers and other scenarios. They mainly serve the elderly, young children, patients with swallowing dysfunction and other people who are prone to choking when drinking water. The core research and development goal of this type of device is to improve the safety and convenience of drinking water for special groups and reduce the health risks caused by choking.

[0003] Current anti-choking drinking devices have achieved basic anti-choking functions and can reduce the probability of choking to a certain extent. However, the internal water guiding cavity of these devices is mostly a one-piece molded design, with fixed values ​​for the water channel and suction resistance. They lack a dedicated suction force adjustment structure and cannot adjust the resistance according to the user's swallowing ability. Users can only passively adapt to the device's fixed suction force. When a user with weak swallowing ability needs to use this fixed suction force to drink, it is very easy for the suction force to be too strong and the water flow rate to exceed the user's swallowing rhythm, thus causing choking. This problem is an objective deficiency of existing anti-choking drinking devices in adapting to different users' swallowing abilities, and it has become a technical problem that urgently needs to be solved. Specifically, a structure with flexibly adjustable suction force needs to be designed to adapt to the personalized drinking needs of different groups and avoid choking problems caused by excessive suction force. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method and device for controlling choking while drinking, which solves the problem that the suction strength is difficult to adapt to various groups of people.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an anti-choking drinking device, comprising a cup body, a cup lid connected to the top side of the inner wall of the cup body via a sealing ring, an adjustment cavity fixedly connected to the bottom end of the cup lid, an extension tube connected to the bottom end of the adjustment cavity via a splicing assembly, a gravity ball fixedly connected to the bottom end of the extension tube, a through hole for ensuring water flow on the outer wall of the gravity ball, a suction nozzle fixedly connected to the middle of the top end of the cup lid, a rubber pad slidably connected to the inner wall of the adjustment cavity, a connecting tube fixedly connected to the middle of the top end of the rubber pad, the connecting tube slidably connected to the inner wall of the suction nozzle, a spiral sleeve rotatably connected to the inner wall of the cup lid, a spiral rod threadedly connected to the inner wall of the spiral sleeve, the bottom end of the spiral rod fixedly connected to the top end of the rubber pad, a limiting assembly for restricting the rotation of the spiral sleeve fixedly connected to the top end of the cup lid, and a sealing ball provided between the bottom end of the rubber pad and the adjustment cavity.

[0006] Preferably, the splicing assembly includes a splicing sleeve fixed at the bottom of the adjustment cavity. The inner wall of the splicing sleeve has a groove, and a limiting ring is provided in the groove of the inner wall of the splicing sleeve. The inner circumference of the limiting ring is fixedly connected to the outer wall of the extension tube, and the limiting ring has the same size as the groove of the inner wall of the splicing sleeve.

[0007] Preferably, the limiting component includes a limiting sleeve one fixed at the top of the cup lid, a limiting sleeve two rotatably connected to the outer wall of the limiting sleeve one, a locking sleeve fixedly connected to the right end of the limiting sleeve one, a locking tenon fixedly connected to the right end of the limiting sleeve two, and a protrusion on the locking tenon abutting against the inner wall of the locking sleeve.

[0008] Preferably, the right end of the locking sleeve is provided with a lever, the locking sleeve is elastic, and the inner circumference of the limiting sleeve is provided with teeth that mesh with the spiral sleeve.

[0009] Preferably, the outer periphery of the bottom end of the rubber pad is lower than the inner periphery of the bottom end of the rubber pad, the bottom end of the rubber pad is conical, and the bottom side of the inner wall of the adjustment cavity is provided with an inverted conical shape opposite to the bottom end of the rubber pad.

[0010] Preferably, the suction nozzle is a flat, bionic nipple that fits the oral cavity, is made of medical-grade silicone, and has an arc-shaped top side.

[0011] Preferably, a filter screen for filtering impurities in the water is fixedly connected to the outer wall of the gravity ball, and a handle is fixedly connected to the outer wall of the cup, with a platform for placing the thumb at the top of the handle.

[0012] Preferably, both the extension tube and the gravity ball are made of medical-grade silicone.

[0013] A method for preventing choking while drinking water includes the following steps: Step 1: Assemble the device. Insert the limiting ring on the outer wall of the extension tube into the groove on the inner wall of the splicing sleeve at the bottom of the adjustment cavity to complete the splicing and fixing of the extension tube and the adjustment cavity. After pouring drinking water into the cup, seal the cup lid on the top of the cup body with the sealing ring. Step 2: Adjust the suction force. Rotate the screw sleeve at the top of the cup lid. The screw sleeve engages with the screw rod, causing the screw rod to rise and fall, which in turn pushes the rubber pad to slide along the inner wall of the adjustment cavity. Adjust the position of the rubber pad in the adjustment cavity according to the user's swallowing ability to achieve precise matching of suction force. Step 3: Limiting and fixing. After the rubber pad position is adjusted, rotate the second limiting sleeve so that its locking tenon engages with the locking sleeve of the first limiting sleeve. The rotation of the spiral sleeve is restricted by the tooth meshing, so as to prevent the rubber pad position from shifting during drinking. Step 4: Drinking water. The user holds the flat bionic mouthpiece in their mouth and gently sucks in water. The negative pressure generated by sucking causes the sealing ball to move upward and detach from the bottom of the adjustment chamber. The water in the cup flows out of the mouthpiece through the through hole on the gravity ball, the extension tube, the adjustment chamber, and the connecting tube, for the user to drink. Step 5: Post-use processing. Pry open the lever of the locking sleeve to separate the locking tenon from the locking sleeve, release the limit of the spiral sleeve, and readjust the position of the rubber pad or disassemble the cup lid and extension tube. Clean all parts of the device. Impurities in the water filtered by the filter screen are cleaned as the parts are disassembled.

[0014] Preferably, in step two, when the spiral sleeve rotates, it drives the spiral rod to rise and fall in the vertical direction. The inverted conical structure at the bottom of the rubber pad is relatively fitted with the conical structure on the bottom side of the inner wall of the adjustment cavity. The suction force can be adjusted in stages by adjusting the gap between the two. In step four, the sealing ball only moves upward under the negative pressure generated by the user's light inhalation. When there is no negative pressure, the sealing ball falls naturally and fits the bottom of the adjustment cavity to stop the water. During the drinking process, the water in the cup is filtered through the filter screen on the outer wall of the gravity ball and then enters the extension tube through the through hole. In step five, the extension tube is disassembled by directly pulling the limiting ring out of the inner wall groove of the splicing sleeve. Each medical silicone component can be cleaned and reused individually.

[0015] Working principle: When using, first rotate the screw sleeve on the inner wall of the cup lid according to the user's actual swallowing ability. The screw sleeve and the screw rod are connected by a threaded transmission. During the rotation, the screw rod moves up and down in the vertical direction, which in turn pushes the rubber pad fixed at its bottom end to slide smoothly in the vertical direction on the inner wall of the adjustment cavity. The suction force can be adjusted by adjusting the gap between the rubber pad and the adjustment cavity. After adjusting the suction strength, rotate the second limiting sleeve at the top of the lid, causing its locking tenon to engage with the locking sleeve on the outside of the first limiting sleeve. The elastic structure of the locking sleeve and the protrusion of the locking tenon abut against each other to achieve locking and limiting. At the same time, the teeth on the inner circumference of the second limiting sleeve tightly engage with the outer wall of the spiral sleeve. Through the limiting of the mechanical structure, the rotation of the spiral sleeve is completely restricted, preventing the rubber pad from shifting due to external forces such as hand touch or cup shaking during drinking, thus ensuring continuous suction strength. When drinking, the user holds the spout at the top of the lid and gently sucks water. The negative pressure generated by sucking in the mouth is quickly transmitted to the inside of the adjustment chamber. The negative pressure force drives the sealing ball upward and disengages from the bottom of the adjustment chamber, thereby opening the complete water passage. Under the influence of gravity, the drinking water in the cup first flows through the filter screen on the outer wall of the gravity ball, filtering out fine impurities in the water. The filtered clean water then enters the extension tube through the through hole on the gravity ball, and then flows through the adjustment chamber and connecting tube in sequence, finally flowing out from the spout for the user to drink. The gravity ball, relying on its own gravity characteristics, ensures that the through hole is always below the water surface at any tilt angle of the cup, achieving all-angle water guidance and adapting to different drinking postures such as lying flat, lying on the side, and sitting. When the user stops sucking, the negative pressure in the mouth quickly disappears, and the sealing ball falls naturally under its own gravity, re-fitting tightly against the bottom of the adjustment chamber, achieving rapid and precise water stoppage and avoiding choking problems caused by residual water flowing or leakage. In addition, the sealing ring between the cup body and the lid effectively ensures the sealing performance of the cup body, preventing leakage and seepage during drinking. The thumb rest platform at the top of the handle on the outer wall of the cup body is designed to fit human grip habits, greatly improving the stability of the user's grip, especially suitable for the elderly with limited mobility and young children. The extension tube is connected to the splicing sleeve at the bottom of the adjustment cavity through the limiting ring on the outer wall, which not only ensures the structural stability of the water guide channel, but also allows for quick disassembly and assembly, facilitating deep cleaning of each component after actual use. The spout, extension tube, and gravity ball are all made of medical-grade silicone, which has good flexibility, hygiene, and aging resistance, making it suitable for long-term repeated use. Impurities in the water filtered by the filter can be thoroughly cleaned when the extension tube is disassembled, ensuring drinking water hygiene from the source. All components work together according to their functions, achieving the core functions of preventing choking while drinking water from multiple aspects such as precise control of water output, synchronous water flow, adaptation to drinking posture, and safe and hygienic use.

[0016] This invention provides a method and device for controlling choking and coughing while drinking water. It has the following beneficial effects: 1. This invention uses the threaded transmission between the spiral sleeve and the spiral rod to drive the rubber pad to slide vertically within the adjustment cavity. Then, by utilizing the linkage between the sealing ball and the suction negative pressure, the sealing ball opens the water passage only under the negative pressure generated by the appropriate suction force. When there is no negative pressure, it quickly falls and seals the bottom of the adjustment cavity, preventing residual water from flowing out. This achieves flexible adjustment of the suction force and allows for precise adjustment of suction resistance and water flow rate according to the user's swallowing ability.

[0017] 2. This invention uses a gravity ball to guide water at any tilt angle of the cup by relying on its own properties, while a limiting component fixes the adjusted spiral sleeve to prevent the rubber pad from shifting during drinking, ensuring the stability of the suction force after adjustment, and avoiding choking caused by improper suction force from the source.

[0018] 3. This invention enables quick and easy assembly and disassembly by hand through the interlocking structure of the limiting ring and the splicing sleeve, without the need for tools. It facilitates deep cleaning of each component. The nozzle, extension tube, and gravity ball are all made of medical-grade silicone, which is safe, odorless, washable, and conforms to oral cavity and usage needs. The cup handle is equipped with a thumb placement platform to improve grip stability and is suitable for use by special groups such as the elderly and children with weaker operational abilities.

The extension tube 7 is the water guiding channel between the cup body and the adjustment cavity. It is detachably connected to the adjustment cavity 6 through the splicing sleeve 12 and the limiting ring 11. The gravity ball 8 uses its own gravity to guide water at all angles. The through hole 10 is the core water guide port of the gravity ball 8, ensuring smooth water flow. The mouthpiece 5 is the user's direct drinking port. One end of the connecting tube 14 is connected to the rubber pad 13. The other end extends into the inner wall of the suction nozzle 5, forming the final water outlet channel from the adjustment chamber to the suction nozzle. The rubber pad 13 is the core component for adjusting the suction force. It works with the spiral rod 15 and the spiral sleeve 16 to achieve vertical position adjustment. The limiting sleeve 17, the locking sleeve 18, the limiting sleeve 29, and the locking tenon 20 together form a limiting component, which is used to restrict the rotation of the adjusted spiral sleeve 16 and fix its position. The blocking ball 21 is set between the bottom of the adjustment chamber 6 and the rubber pad 13. It is the core control component for the water passage opening and closing.

[0023] The splicing sleeve 12, fixed at the bottom of the adjusting cavity 6, has a groove on its inner wall. A limiting ring 11 is installed in the groove of the inner wall of the splicing sleeve 12.

The engaging connection method requires no tools, allowing for quick and easy manual assembly and disassembly, facilitating subsequent deep cleaning of the water guiding components. The lever on the right end of the engaging sleeve 18 provides a point of leverage for the user, allowing the user to manually pry open the engaging sleeve 18, causing its elastic structure to deform and thus quickly separating the engaging tenon 20 from the engaging sleeve 18, releasing the restriction on the limiting sleeve 19. The teeth on the inner circumference of the limiting sleeve 19 and the spiral sleeve 1... The outer walls of the 6-section are tightly engaged, mechanically restricting the rotation of the spiral sleeve 16.

The detailed design of each component is based on the core needs of preventing choking, high adaptability, easy operation, and hygiene, so that the structural design of the device is highly consistent with actual use needs and improves the overall use effect.

[0024] A method for preventing choking while drinking water includes the following steps: Step 1: Assemble the device. Insert the limiting ring 11 on the outer wall of the extension tube 7 into the groove on the inner wall of the splicing sleeve 12 at the bottom of the adjustment cavity to complete the splicing and fixing of the extension tube 7 and the adjustment cavity. After injecting drinking water into the cup body 1, seal the cup lid 3 on the top of the cup body 1 with the sealing ring 4. Step 2: Adjust the suction force. Rotate the screw sleeve 16 at the top of the cup lid 3. The screw sleeve 16 drives the screw rod 15 to rise and fall through the thread engagement with the screw rod 15, thereby pushing the rubber pad 13 to slide along the inner wall of the adjustment cavity. Adjust the position of the rubber pad 13 in the adjustment cavity according to the user's swallowing ability to achieve precise matching of suction force. Step 3: Limiting and fixing. After the position of the rubber pad 13 is adjusted, rotate the limiting sleeve 29 so that the locking tenon 20 on it is engaged in the locking sleeve 18 of the limiting sleeve 17. The rotation of the spiral sleeve 16 is restricted by the tooth meshing to prevent the position of the rubber pad 13 from shifting during drinking. Step 4: Drinking water. The user holds the flat bionic mouthpiece 5 in their mouth and gently sucks in water. The negative pressure generated by sucking causes the sealing ball 21 to move upward and disengage from the bottom of the adjustment chamber. The water in the cup body 1 flows out of the mouthpiece 5 through the through hole 10 on the gravity ball 8, the extension tube 7, the adjustment chamber, and the connecting tube 14, for the user to drink. Step 5: Post-use processing. Pry open the lever of the locking sleeve 18 to separate the locking tenon 20 from the locking sleeve 18, release the limit of the spiral sleeve 16, and readjust the position of the rubber pad 13 or disassemble the cup lid 3 and extension tube 7. Clean all parts of the device. The impurities in the water filtered by the filter screen 9 are cleaned as the parts are disassembled.

[0025] In step two, when the spiral sleeve 16 rotates, it drives the spiral rod 15 to rise and fall in the vertical direction. The inverted conical structure at the bottom of the rubber pad 13 is in relative contact with the conical structure on the bottom side of the inner wall of the adjustment cavity. The suction force can be adjusted in stages by adjusting the gap between the two. In step four, the sealing ball 21 moves upward only under the negative pressure generated by the user's light suction. When there is no negative pressure, the sealing ball 21 falls naturally and fits the bottom of the adjustment cavity to stop the water. During the drinking process, the water in the cup body 1 is filtered through the filter screen 9 on the outer wall of the gravity ball 8 and then enters the extension tube 7 through the through hole 10. In step five, the extension tube 7 is disassembled by directly pulling the limiting ring 11 out of the inner wall groove of the splicing sleeve 12. Each medical silicone material component can be cleaned and reused individually.

A method for controlling choking while drinking water according to claim 9, characterized in that, In step two, when the spiral sleeve (16) rotates, it drives the spiral rod (15) to rise and fall in the vertical direction. The inverted conical structure at the bottom of the rubber pad (13) is in relative contact with the conical structure on the bottom side of the inner wall of the adjustment cavity. The suction force is adjusted in stages by adjusting the gap between the two. In step four, the sealing ball (21) moves upward only under the negative pressure generated by the user's light inhalation. When there is no negative pressure, the sealing ball (21) falls naturally and fits the bottom of the adjustment cavity to stop the water. During the drinking process, the water in the cup (1) is filtered by the filter screen (9) on the outer wall of the gravity ball (8) and then enters the extension tube (7) through the through hole (10). In step five, the extension tube (7) is disassembled by directly pulling the limiting ring (11) out of the inner wall groove of the splicing sleeve (12). Each medical silicone material component can be cleaned and reused separately.
