Description

Technical Field

[0001] This utility model relates to a spoon, and more particularly to a temperature-measuring straw spoon, belonging to the field of tableware technology in daily necessities. Background Technology

[0002] Elderly people who are bedridden need to control the amount of water they drink, generally 3-5 ml. Drinking too much liquid can easily cause choking. Therefore, these patients often use a graduated spoon to drink water. Using a spoon helps control the amount of water consumed each time. For example, choosing a 5 ml spoon means that each serving will only contain a maximum of 5 ml, avoiding choking from drinking too much liquid at once. Additionally, water that is too hot can burn the mouth or esophagus, while water that is too cold may affect the eating experience or cause gastrointestinal discomfort. Therefore, some tableware with temperature measurement functions and food intake restrictions have appeared on the market for such patients. For example, Chinese utility model patent CN202020209U discloses a temperature-measuring spoon, which includes a spoon handle and a spoon body fixedly connected to the front end of the spoon handle. The end of the spoon handle has a backward bend. The spoon body has a hollow structure made of heat-conducting material. An electronic thermometer is embedded in the middle of the spoon handle. The electronic thermometer includes a temperature sensing probe, a control chip, and a display. The temperature sensing probe extends into the cavity of the spoon body and contacts the inner wall of the cavity. The temperature sensing probe is connected to the input end of the control chip through a wire. The output end of the control chip is connected to the display. The display is exposed on the outer surface of the spoon handle. However, this product only has scooping and temperature measurement functions, which still presents inconveniences for elderly people who are bedridden for many years: some patients with swallowing difficulties will spill food everywhere when being fed with a spoon while drinking nutritional solutions or liquids; moreover, some patients cannot sit up completely to eat, for example, in a semi-recumbent position with the head of the bed raised to 40 or 50 degrees. In this case, it is easy for liquids to leak out of the mouth when fed with a spoon, increasing the difficulty of care; at the same time, using a straw can exercise the patient's oral muscles and help their swallowing function recover. Therefore, currently, when using a temperature-measuring spoon, a straw is also required. Frequent switching of tools is not only cumbersome but may also increase the risk of food spillage. Therefore, how to develop a spoon with an integrated straw structure and temperature measurement function has become a research direction. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0016] Example: A temperature-measuring straw spoon, configured as follows Figure 1As shown, the device includes a temperature display 1, a temperature sensing element 2, a spoon body 3, and a spoon handle 4. The spoon body 3 has an arc-shaped groove structure for scooping food. The spoon body 3 and spoon handle 4 are integrally molded and are made of food-grade silicone, which is soft and has a temperature resistance range of -40℃ to 200℃. The spoon handle 4 serves as a hollow straw, with its inner cavity extending towards the bottom of the spoon body 3 and communicating with the interior of the spoon body 3. The spoon body 3 has a capacity of 5ml and is also equipped with graduations to indicate the volume, meeting the swallowing needs of patients with swallowing difficulties and preventing choking and aspiration due to excessive intake at one time. Figure 2 As shown, the spoon handle 4 has an insulating layer 401 inside. The insulating layer 401 is made of a high-temperature resistant sealing material, such as silicone or polytetrafluoroethylene. The insulating layer 401 divides the inner cavity of the spoon handle 4 into a wiring cavity 402 and a hollow cavity 403. The sealing properties of the insulating layer 401 can effectively prevent liquids (such as soup or beverages) from entering the wiring cavity 402, avoiding short circuits, and at the same time preventing the wires in the wiring cavity 402 from contacting food, ensuring safe use. The temperature display 1 is located on one side of the spoon handle 4, and the temperature sensing element 2 is located at the bottom of the spoon body 3 and is electrically connected to the temperature display 1 through the wiring cavity 402. The temperature sensing element 2 is a K-type thermocouple (0.5mm in diameter), and the temperature sensing end of the temperature sensing element 2 is in contact with the inner surface of the bottom of the spoon body 3. The spoon body 3 has multiple filter holes 5 communicating with the hollow cavity 403. The filter holes 5 have a diameter of 1mm and are evenly distributed on both sides of the spoon body 3 near the handle 4. These filter holes are used to filter food residue during consumption, preventing blockage of the hollow cavity. The upper end of the handle 4 extends to form a suction nozzle 6. The suction nozzle 6 conforms to the contours of the human lip, making consumption more comfortable and reducing liquid leakage. It can also be connected to an external hose for rinsing the hollow cavity 403. Figure 3 As shown. Further, the temperature display 1 includes a first housing 103, a second housing 104, a display screen 101, and a circuit board 102. The display screen 101 is a small LCD digital display, and the circuit board 102 uses an STM32 series microcontroller, which integrates a temperature acquisition chip 110, a microprocessor 107, a power module 108, and a button battery 109. The button battery 109 supplies power to the temperature acquisition chip 110 and the microprocessor 107 via the power module 108. The temperature acquisition chip 110 is electrically connected to the temperature sensing element 2, and the circuit board 102 is electrically connected to the display screen 101. Figure 4As shown, the first housing 103 and the spoon body 3 are integrally formed. The end face of the first housing 103 is provided with a first connecting part 105, which has an internal thread. The side of the second housing 104 is provided with a second connecting part 106, which has an external thread that mates with the internal thread. The display screen 101 is embedded in the middle of the second housing 104. When the spoon body 3 comes into contact with food, the thermocouple converts the temperature signal into an electrical signal. After being processed by the circuit board 102, the specific temperature value (accuracy ±0.5℃) is displayed on the display screen 101 in real time, making it convenient for users to read intuitively and avoiding burns to the mouth or esophagus due to excessively hot food, or gastrointestinal discomfort due to excessively cold food.

[0017] This invention integrates the functions of scooping (solid or semi-solid food) and sucking (liquid or liquid food) by designing the spoon handle 4 as a hollow straw extending to the bottom of the spoon body 3, and setting a filter hole 5 in the spoon body 3 that communicates with the hollow cavity 403. This eliminates the need for frequent tool switching, making it especially suitable for feeding bedridden elderly people or those with swallowing difficulties, reducing operational complexity and the risk of food spillage. The temperature sensing end of the temperature sensing element 2 is tightly fitted to the inner surface of the bottom of the spoon body 3, allowing for direct and accurate contact with the food and rapid temperature feedback. The temperature display 1 is connected to the temperature sensing element 2 through wiring in the wiring cavity 402, displaying temperature data in real time on the screen 101, facilitating precise control of food temperature and preventing burns or gastrointestinal discomfort. In addition, the present invention divides the inner cavity into a wiring cavity 402 (accommodating the wiring) and a hollow cavity 403 (sucking channel) through the isolation layer 401 inside the spoon handle 4. The isolation layer 401 is made of high temperature resistant sealing material, which effectively prevents liquid from entering the wiring cavity 402 and damaging the circuit, while avoiding contact between the wiring and food, thus ensuring safe use.

[0018] Work process When using the spoon 3 to scoop semi-solid foods such as porridge or rice paste, the food directly contacts the bottom of the spoon 3. The temperature sensing element 2 quickly detects the food temperature and transmits the signal to the circuit board 102 via wires. After processing, the temperature value (e.g., 55℃) is immediately displayed on the display screen 101. Users can judge whether the food is suitable for consumption based on the displayed temperature (e.g., the recommended temperature for food for infants or the elderly is 38-45℃). If the temperature is too high, wait for it to cool down before feeding. When sucking liquid foods such as soup or juice, the spoon 3 is immersed in the food. The liquid enters the hollow cavity 403 through the filter hole 5 (to intercept residue) at the bottom of the spoon 3, and the user sucks it through the mouthpiece 6. At the same time, the temperature sensing element 2 is in direct contact with the liquid, monitoring the liquid temperature in real time and displaying it on the display screen 101 to ensure temperature safety during sucking. During this process, the isolation layer 401 effectively prevents liquid from entering the wiring cavity 402, ensuring the normal operation of the circuit.

[0019] In summary, this invention enables real-time and accurate monitoring of food temperature; by setting a filter hole in the spoon body that communicates with the hollow cavity, it integrates scooping and sucking functions, adapting to foods in different states.
