[0003] In the cooking process, accurately controlling the temperature of ingredients and cookware is crucial for controlling the heat, ensuring the taste and safety of food. Traditional methods mainly rely on the chef's experience or the use of separate probe-type or infrared thermometers, but these methods have the following problems: Purely mechanical spatulas: They only have the functions of stir-frying and scooping. Temperature control relies on user experience or an external timer to control cooking time. They are prone to misjudging the heat, resulting in food being undercooked, overcooked, or producing harmful substances. They are cumbersome to operate and easy to make cooking mistakes due to distraction.

[0004] External probe or infrared temperature measurement solutions: These require holding an independent probe or temperature gun, which occupies one hand and is intermittent in operation. Furthermore, infrared methods can only measure surface temperature and cannot accurately sense the internal temperature of oil, broth, or thick steaks. Probe-based solutions also have problems such as the insertion hole damaging the integrity of the food and being troublesome to clean. Therefore, a timed spatula with temperature detection function is proposed to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 - Figure 4 This utility model provides an embodiment of a timed spatula with temperature detection function, comprising a spoon head 1 for scooping or stir-frying food and a handle 2 for gripping. The spoon head 1 and handle 2 are threadedly connected. The spoon head 1 is made of food-grade 304 stainless steel, and the handle 2 is mainly made of high-temperature resistant engineering plastic. The overall structure meets the long-term use requirements in a kitchen environment. The handle 2 has a detachable structure, including an upper cover 21 and a lower cover 22. The lower surface of the upper cover 21 fits against the upper surface of the lower cover 22, forming a receiving cavity 20 between the upper cover 21 and the lower cover 22. The receiving cavity 20 contains: The detection component 3 is used to collect the working temperature of the spoon head 1 in real time. The detection component 3 includes a thermocouple sensor 31 embedded in the end of the spoon head 1 and a control circuit board 32 arranged in the receiving cavity 20. The signal output terminal of the thermocouple sensor 31 is connected to the control circuit board 32 located inside the handle 2. The control circuit board 32 integrates a microcontroller, a power management unit and a display driver circuit. The timer button 4 is embedded on the upper surface of the control circuit board 32 and is used to generate an end signal according to the set duration. The timer button 4 and the detection component 3 are linked by software. When the real-time temperature is higher than the set safety threshold, the timer button 4 automatically shortens the remaining countdown or immediately triggers the alarm prompt component 5 to prevent the food from overheating due to the user forgetting to turn off the stove. Alarm prompting component 5 is installed inside the receiving cavity 20 and is used to emit a prompting sound and flashing light when an arrival signal is received; The power supply component 6 provides power to the detection component 3, the control circuit board 32, and the alarm component 5. The handle 2 has a battery compartment 60 inside, which contains a replaceable CR2032 button battery 61. The power management unit monitors the voltage of the button battery 61 and flashes an LED indicator 51 to indicate when the battery is low. The handle 2 has a threaded tail sleeve 62 for removing the button battery 61, so that the handle 2 can be opened for maintenance or battery replacement without the aid of tools.

[0020] Reference Figure 2 and Figure 3 The control circuit board 32 has a display screen 33 near the timer button 4. The display screen 33 is an OLED screen. The display surface of the display screen 33 is exposed to the window 212 of the upper cover 21. It is used to display the current temperature and the remaining time in real time. The control circuit board 32 is configured with a temperature monitoring mode and a timed cooking mode. The temperature monitoring mode can collect and display the temperature in real time. When the temperature exceeds the preset safety threshold, the alarm prompt component 5 is triggered. When the timed cooking mode is enabled, the user sets the countdown through the timer button 4. When the time is up, the sound and light alarm will be automatically activated to remind that the cooking is complete.

[0021] Reference Figure 2 and Figure 3 Thermocouple sensor 31 adopts a K-type metal probe structure. The thermocouple sensor 31 is model WRN-230. The metal probe monitoring end of thermocouple sensor 31 is located inside the cavity of spoon head 1 and is in contact with the inner wall of spoon head 1. The temperature resistance range is 0℃ to 1100℃.

[0022] Reference Figure 3 and Figure 4The timing button 4 is a press-type composite encoder. Pressing it once enters the timing setting mode, pressing it again increases the set time, and pressing and holding it exits the setting mode. The set time range is 1 minute to 30 minutes, and the step unit is 1 minute. The signal output terminal of the timing button 4 is connected to the control circuit board 32. When the countdown reaches zero, the timing button 4 outputs a pulse signal to the alarm prompt component 5 through the control circuit board 32.

[0023] Reference Figure 3 and Figure 4 The alarm indicator component 5 includes an LED indicator 51 installed at the front end of the receiving cavity 20 near the spoon head 1, and a buzzer 52 arranged inside the tail end of the lower cover 22. Both the buzzer 52 and the LED indicator 51 are electrically connected to the control circuit board 32. The LED indicator 51 emits blue light to indicate normal operation, and flashes red light to indicate high temperature alarm or timer termination. The light from the LED indicator 51 passes through the window 212 of the upper cover 21 to form a light strip, which works synchronously with the buzzer 52 to provide dual prompts in a noisy kitchen environment.

[0024] Reference Figure 4 The seam between the upper cover 21 and the lower cover 22 is provided with a food-grade silicone sealing ring 23, which makes the cavity 20 reach the IPX5 waterproof rating and prevents steam or washing water from entering the internal circuit area and causing circuit corrosion.

[0025] Reference Figure 3 A heat insulation sleeve 7 is provided between the spoon head 1 and the handle 2. The heat insulation sleeve 7 is made of PPSU material to reduce the temperature rise of the handle 2 and protect the internal electronic components.

[0026] Reference Figure 2 - Figure 4 The lower cover 22 of the handle 2 is fixedly connected to a fixing block 8 by bolts, which is used to limit the installation of the control circuit board 32, buzzer 52 and button battery 61. All electronic components are partially encapsulated with potting compound to enhance shock resistance and moisture resistance.

[0027] Working principle: In use, the user first unscrews the tail sleeve 62 at the end of the handle 2 to check or replace the button battery 61, then tightens the tail sleeve 62 again to ensure a reliable power connection. Pressing the timer button 4 once powers on the device and puts it into standby mode. The OLED display screen 33 then lights up, displaying the current ambient temperature. When the spoon head 1 comes into contact with a hot pan, hot oil, or food, the K-type thermocouple sensor 31 embedded inside the spoon head 1 senses the temperature change and transmits the thermoelectric potential signal to the control circuit board 32. The microcontroller on the control circuit board 32 collects and processes the signal, converts it into a precise temperature value, and updates it on the display screen 33 in real time.

[0028] When the user is performing operations that require timing, such as frying eggs or stir-frying vegetables, they can press the timer button 4 to enter the timed cooking mode: press it once to enter the setting state, press it again to increase the time by 1 minute until the desired time is set, for example, frying eggs requires a timer of 3 minutes, and then press and hold the timer button 4 to exit the setting. At this time, the display screen 33 will simultaneously display the remaining countdown time.

[0029] During the countdown, the system continuously monitors the temperature. Once the real-time temperature exceeds the preset safety threshold, such as 230°C for cooking oil smoke, the control circuit board 32 determines that there is a risk of overheating and immediately triggers the alarm prompt component 5. The buzzer 52 emits a high-frequency buzzing sound, and at the same time, the LED indicator 51 changes from blue light to red light and flashes rapidly, achieving a dual warning of sound and light.

[0030] When the countdown reaches zero, regardless of whether the temperature exceeds the limit, the control circuit board 32 will output a pulse signal to the alarm prompt component 5 to start the standard reminder process, prompting the user to flip the food or remove it from the pot. After cooking, the device will automatically shut down after 30 seconds of inactivity to save power.

[0031] During cleaning, the user can rinse the entire spatula. Due to the protection of the silicone sealing ring 23 and the potting compound, moisture is difficult to penetrate into the receiving cavity 20, thus improving the protection effect. When the button battery 61 needs to be replaced, the tail sleeve 62 can be unscrewed, and then the handle 2 can be rotated relative to the spoon head 1 so that the spoon head 1 can be removed from the thread of the handle 2. The upper cover 21 and the lower cover 22 can then be disassembled and separated for the replacement or repair of internal components.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
