Description

Technical Field

[0001] This utility model relates to the field of thermos cup technology, and in particular to a thermos cup that prevents choking. Background Technology

[0002] Insulated water bottles are commonly used drinking vessels in daily life, and are widely used in various scenarios such as studying, working, and outdoor activities due to their ability to effectively maintain water temperature and their portability. However, traditional insulated water bottles have a relatively common safety hazard during use: choking on water.

[0003] Most insulated water bottles on the market currently use a direct-drinking design with an open lid. When a user drinks from a bottle at an excessively steep angle, their head is tilted upwards, and a large amount of water may suddenly rush into their mouth, causing them to choke before they can swallow. This risk is even higher for children and the elderly, whose swallowing control is relatively weaker. Choking not only causes physical discomfort but can also lead to serious health problems such as airway obstruction.

[0004] Therefore, a thermos cup designed to prevent choking is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a thermos cup that prevents choking, thereby solving or at least alleviating one or more of the above-mentioned problems and other issues existing in the prior art.

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A thermos cup with anti-choking mechanism includes a thermos cup body and an anti-choking component. The thermos cup body is threaded with a lid at its upper end. The lid has a water outlet and an air vent. The anti-choking component includes a groove and a baffle. The groove is located at the bottom of the lid and is connected to the lower end of the air vent. The baffle is hinged inside the groove. When the lid is tilted at an angle greater than 30°, the baffle can fit against the lower end of the air vent to block it and reduce the flow rate of water from the outlet.

[0008] In a thermos cup according to the present invention, a drinking spout is fixedly embedded in the water outlet.

[0009] In a thermos cup according to the present invention, the drinking spout is a transparent silicone spout.

[0010] In a thermos cup according to the present invention, the drinking spout is provided in the shape of a flat frustum.

[0011] According to the present invention, a thermos cup for preventing choking is provided, wherein a first pin is fixedly connected to the cup lid, the upper cover is rotatably sleeved on the first pin, a first torsion spring is sleeved on the first pin, one end of the first torsion spring abuts against the top of the cup lid, and the other end of the first torsion spring abuts against the bottom of the upper cover, a slot is provided on the side of the upper cover, and an assembly groove is provided on the side of the cup lid, a second pin is fixedly connected in the assembly groove, a buckle is rotatably sleeved on the second pin, a second torsion spring is sleeved on the second pin, the upper end of the second torsion spring abuts against one side of the buckle, and the other end of the second torsion spring abuts against the inner wall of the assembly groove, and a buckle head is formed at the upper end of the buckle, the buckle head being able to engage in the slot.

[0012] According to the present invention, a thermos cup for preventing choking is provided, wherein the upper cover has an inner cavity, a control module is installed inside the inner cavity, a display screen is embedded on the surface of the upper cover, a temperature sensor is embedded in the bottom of the cup lid, the temperature sensor is electrically connected to the signal input terminal of the control module, and the display screen is electrically connected to the signal output terminal of the control module.

[0013] In a thermos cup according to the present invention, a button is embedded inside the slot, the button is electrically connected to the signal input terminal of the control module, and a speaker is installed inside the inner cavity, the speaker being controlled by the control module.

[0014] In a thermos cup according to the present invention, a battery for power supply is installed inside the inner cavity.

[0015] This utility model has at least the following beneficial effects:

[0016] Based on the principles of fluid mechanics and air pressure balance, the cup uses a tilt-triggered baffle structure to automatically block the air hole when the cup is tilted at an angle of more than 30°. This negative pressure reduces the water flow rate, effectively reducing the risk of choking compared to traditional thermos cups. It is especially suitable for children, the elderly, and other people with weaker swallowing abilities.

[0017] The flat, round, transparent silicone drinking spout combines ergonomic design with practicality. On the one hand, it disperses the impact of water flow by increasing the contact area of ​​the lips, and on the other hand, the transparent material makes it easy to observe the internal cleanliness. The flexible material improves the fit and comfort and reduces liquid spillage.

[0018] The integrated temperature sensor and control module enable real-time water temperature monitoring and over-temperature warning. When the water temperature exceeds the threshold when the lid is opened, the speaker will automatically sound an alarm, reducing the risk of accidental scalding and significantly improving the safety factor.

[0019] The automatic opening and closing lid structure is driven by dual torsion springs. Pressing the buckle will automatically pop up the lid. With the help of double sealing blocks, the operation is improved by about 50% while ensuring the sealing performance. The entire process of opening, drinking and closing the lid can be completed with one hand. Attached Figure Description

[0030] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0031] Please refer to Figures 1 to 7As shown, an embodiment of this utility model provides a thermos cup with anti-choking properties, including a thermos cup body 1 and an anti-choking component. A cup lid 2 is threaded onto the upper end of the thermos cup body 1. The cup lid 2 has a water outlet 201 and an air hole 202. The anti-choking component includes a groove 203 and a baffle 204. The groove 203 is located at the bottom of the cup lid 2 and is connected to the lower end of the air hole 202. The baffle 204 is hinged inside the groove 203. When the cup lid 2 is tilted at more than 30°, the baffle 204 can fit against the lower end of the air hole 202 to block the air hole 202 and reduce the flow rate of water from the water outlet 201.

[0032] When in use, when the insulated cup body 1 is tilted at an angle ≤30°, the air hole 202 remains unobstructed, and air enters the cup body 1 through the air hole, so that the internal and external air pressure is balanced, and water can flow out smoothly from the outlet 201; when the insulated cup body 1 is tilted at an angle >30°, the baffle 204 rotates around the hinge point due to gravity and fits against the air hole 202, blocking the air from entering, forming a negative pressure inside the cup, and the water flow rate decreases due to the reduced air pressure difference, preventing choking.

[0033] In this embodiment, a drinking spout 2011 is fixedly embedded on the water outlet 201. The drinking spout 2011 serves as an extension of the water outlet 201, changing the shape of the water outlet to make the water flow more concentrated, making it easier for users to drink, while preventing liquid from overflowing.

[0034] Furthermore, in this embodiment, the drinking spout 2011 is a transparent silicone spout. The transparent silicone material combines flexibility and visibility: its flexibility conforms to the human lip, improving drinking comfort; its transparency allows the user to observe the inner wall of the drinking spout 2011, facilitating cleaning of the inner wall.

[0035] Furthermore, the drinking spout 2011 features a flattened frustum shape. This shape increases the contact area of ​​the lips, dispersing the water flow into a wider plane, reducing the impact force per unit area, further minimizing the risk of choking, and also conforming to ergonomic design.

[0036] In this embodiment, a first pin is fixedly connected to the cup lid 2, and the upper cover 3 is rotatably sleeved on the first pin. A first torsion spring is sleeved on the first pin. One end of the first torsion spring abuts against the top of the cup lid 2, and the other end of the first torsion spring abuts against the bottom of the upper cover 3. A slot 301 is provided on the side of the upper cover 3, and an assembly groove 205 is provided on the side of the cup lid 2. A second pin is fixedly connected in the assembly groove 205. A buckle 206 is rotatably sleeved on the second pin. A second torsion spring is sleeved on the second pin. The upper end of the second torsion spring abuts against one side of the buckle 206, and the other end of the second torsion spring abuts against the inner wall of the assembly groove 205. A buckle head 207 is formed on the upper end of the buckle 206, and the buckle head 207 can be inserted into the slot 301.

[0037] When in use, the opening process is as follows: Press the lower end of the buckle 206 to make it rotate around the second pin, the buckle 207 disengages from the slot 301, and the first torsion spring releases its elastic force to push the upper cover 3 to automatically spring up around the first pin.

[0038] Closing process: Manually press the top cover 3, the buckle 207 is squeezed by the slot 301, causing the buckle 206 to rotate and compress the second torsion spring. After it is in place, the buckle 207 is locked into the slot 301.

[0039] To prevent water leakage inside the thermos 1 during storage, a first sealing block 304 and a second sealing block 305 are fixedly connected to the inner bottom of the upper cover 3. When the upper cover 3 is placed on the cup lid 2, the first sealing block 304 squeezes and seals the air hole 202, and the second sealing block 305 squeezes and seals the drinking spout 2011.

[0040] In this embodiment, the upper cover 3 has an inner cavity 303, and the control module 6 is installed inside the inner cavity 303. The surface of the upper cover 3 is embedded with a display screen 4, and the bottom of the cup lid 2 is embedded with a temperature sensor 5. The temperature sensor 5 is electrically connected to the signal input terminal of the control module 6, and the display screen 4 is electrically connected to the signal output terminal of the control module 6.

[0041] Temperature sensor 5 monitors the water temperature in the thermos cup 1 in real time and transmits the signal to control module 6. After processing the data, control module 6 displays the water temperature value on display screen 4, allowing users to intuitively obtain temperature information.

[0042] It should be noted that the control module 6 in this embodiment can be a microcontroller of model STM32L071KB, and the temperature sensor 5 is a temperature sensor of model DS18B20.

[0043] Furthermore, a button 302 is embedded inside the card slot 301. The button 302 is electrically connected to the signal input terminal of the control module 6. A speaker 7 is installed inside the cavity 303. The speaker 7 is controlled by the control module 6.

[0044] When the top cover 3 is opened, the buckle 207 disengages from the slot 301, triggering button 302, which sends a signal to control module 6. If the temperature sensor 5 detects that the water temperature is higher than a preset threshold (e.g., 60°C), control module 6 drives speaker 7 to issue an alarm (e.g., "Current water temperature exceeds 60°C, please drink with caution") to prevent the user from accidentally drinking and getting burned.

[0045] Furthermore, a battery for power supply is installed inside the inner cavity 303.

[0046] The battery provides power to the control module 6, display screen 4, temperature sensor 5 and speaker 7 to ensure the normal operation of electronic functions.

[0047] The working principle of the anti-choking thermos cup is summarized as follows:

[0048] I. Core Mechanism for Preventing Choking

[0049] 1. When the tilt angle is ≤30° (normal drinking state)

[0050] The vent 202 is kept open, and air enters the thermos cup body 1 through the vent to balance the internal and external air pressure.

[0051] Water can flow smoothly from the outlet 201, and the drinking spout 2011 (flat frustum-shaped transparent silicone spout) concentrates the water flow, reduces the impact, and makes it easy to drink.

[0052] 2. When the tilt angle is greater than 30° (anti-choking trigger state)

[0053] The baffle 204 rotates around the hinge point due to gravity, and fits against the lower end of the air hole 202 and blocks it.

[0054] The blockage of the pores creates negative pressure inside the cup, and the reduced pressure difference slows down the water flow, preventing choking caused by excessively fast water flow.

[0055] II. Structural Design to Aid in Preventing Choking and Optimizing User Experience

[0056] Water dispenser design 2011

[0057] Material: Transparent silicone, flexible and conforms to the lips, improving drinking comfort; its transparency makes it easy to observe the cleanliness of the inner wall.

[0058] Shape: Flattened frustum shape, which increases the contact area of ​​the lips, disperses the water flow into a wider plane, reduces the impact force per unit area, further reduces the risk of choking, and is ergonomic.

[0059] III. Opening and Sealing Mechanism of the Top Cover

[0060] 1. Opening process

[0061] Pressing down the lower end of buckle 206 causes buckle 207 to disengage from slot 301, and the first torsion spring releases its elasticity to push the top cover 3 to pop up automatically.

[0062] 2. Closing process

[0063] When the top cover 3 is pressed down manually, the buckle 207 is squeezed by the slot 301, causing the buckle 206 to rotate and compress the second torsion spring. After it is in place, the buckle 207 is locked into the slot 301.

[0064] 3. Sealing design

[0065] The first sealing block 304 at the bottom of the inner part of the top cover 3 presses and seals the air hole 202, and the second sealing block 305 presses and seals the drinking spout 2011 to prevent water leakage during storage.

[0066] IV. Temperature monitoring and safety alarm functions

[0067] 1. Temperature display

[0068] Temperature sensor 5 (DS18B20) monitors water temperature in real time, and the signal is transmitted to control module 6 (STM32L071KB), processed, and then displayed on display screen 4.

[0069] 2. High Temperature Alert

[0070] When the top cover 3 is opened, the buckle 207 triggers the button 302 in the slot 301. If the water temperature is higher than the preset threshold (e.g., 60℃), the control module 6 drives the speaker 7 to sound an alarm, reminding the user to avoid accidental scalding.

[0071] V. Power Supply

[0072] The battery inside cavity 303 powers the control module 6, display screen 4, temperature sensor 5 and speaker 7, ensuring the normal operation of electronic functions.

[0073] VI. Overall Logical Summary

[0074] Through the synergistic effect of mechanical structure (baffles, air vents) and electronic modules (temperature monitoring, alarms), the anti-choking thermos achieves dual safety protection of "pressure balance to control water flow and temperature monitoring to prevent scalding," while improving drinking comfort and sealing through ergonomic design.
