It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0024] The various specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, the various possible combinations of the specific technical features in the utility model will not be described separately.

[0026] It should be noted that the terms "comprises", "includes" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device including the element. "Multiple" means greater than or equal to two.
[0027] like Figure 1 As shown, an embodiment of the utility model provides a wireless temperature probe, which can be used for detecting the temperature of an object to be processed in a food processing device such as an oven and a baking oven, wherein the object to be processed generally refers to food materials such as meat to be baked. Specifically, the wireless temperature probe comprises a needle body 1, a first temperature sensor 2, a battery 3 and a heat-conducting structure 4. The needle body 1 comprises a first rod body 11 for inserting into the object to be processed and a second rod body 12 exposed outside the object to be processed, and a separation scale line 13 is arranged between the first rod body 11 and the second rod body 12. The first temperature sensor 2 is arranged in the first rod body 11 and is located at the insertion end 111 of the first rod body 11 to detect the temperature of the object to be processed. The battery 3 is arranged in the first rod body 11 adjacent to the first temperature sensor 2, and the first temperature sensor 2 is electrically connected to the battery 3 to obtain electrical energy, and a heat insulation layer is also provided on the battery 3, which can provide high-temperature protection for the battery 3, ensuring that the battery 3 can normally play a power supply role in the high-temperature food processing equipment. The heat-conducting structure 4 is at least disposed on the inner wall of the insertion end 111 and directly abuts against the first temperature sensor 2 to conduct the heat of the first rod body 11 to the first temperature sensor 2 .
[0028] Specifically, when the wireless temperature probe is used in a food processing device, the temperature of the object to be processed is often lower than the temperature of the internal space of the food processing device. Therefore, the ambient temperature of the first rod body 11 inserted into the object to be processed and the ambient temperature of the second rod body 12 exposed outside the object to be processed are different. If the first rod body 11 is not fully inserted into the object to be processed, so that part of the first rod body 11 is exposed to the internal space of the food processing device, it may affect the accuracy of temperature detection, and may also cause high-temperature damage to the components arranged inside the first rod body 11. In order to avoid the above problems, a dividing scale line 13 is provided between the first rod body 11 and the second rod body 12 to clearly distinguish the first rod body 11 and the second rod body 12. This can prompt the user to fully insert the first rod body 11 into the object to be processed and guide the user to use the wireless temperature probe correctly. Optionally, the dividing scale line 13 can be a physical structure such as a groove or a protrusion located between the first rod body 11 and the second rod body 12. For example, Figure 1 The dividing scale line 13 shown is a groove. Of course, it is understandable that the dividing scale line 13 can also be just a pattern feature such as a drawn mark that plays a marking role, as long as it can play a role in distinguishing the first rod body 11 from the second rod body 12.
[0029] Specifically, the insertion end 111 of the first rod body 11 refers to the end away from the second rod body 12, or can be understood as the end that is first inserted into the object to be processed. This end can usually be set as a tip, so that it can be more easily inserted into the object to be processed and can reduce the extrusion damage to the object to be processed. The first temperature sensor 2 is located at the insertion end 111 and can be inserted into the interior of the object to be processed with the first rod body 11, so as to detect the temperature inside the object to be processed. In this way, the detected temperature is more valuable for judging the degree of processing of the object to be processed, which is conducive to improving the quality of food processing.
[0030] In some embodiments, there is no heat-conducting structure 4 between the first temperature sensor 2 and the inner wall of the insertion end 111. As the use time increases, or due to severe collisions and other reasons, the first temperature sensor 2 may become loose, resulting in poor contact between the first temperature sensor 2 and the inner wall of the insertion end 111, thereby affecting the effect of contact heat transfer, resulting in inaccurate temperature detected by the first temperature sensor 2, untimely response to temperature changes, and other problems. In order to avoid the above problems, the embodiment of the utility model adopts a heat-conducting structure 4 to abut against the first temperature sensor 2. In this way, the heat-conducting structure 4 and the inner wall of the insertion end 111 can jointly limit the contact of the first temperature sensor 2, or the heat-conducting structure 4 and the inner wall of the insertion end 111 can jointly limit the contact of the first temperature sensor 2, so that the first temperature sensor 2 can be better fixed, prevent the first temperature sensor 2 from loosening, and keep the first temperature sensor 2 in stable contact with the inner wall of the insertion end 111. Optionally, the heat-conducting structure 4 can be made of a metal material or a ceramic material with a high thermal conductivity so as to conduct heat to the first temperature sensor 2 more efficiently; the heat-conducting structure 4 can also be made of the same material as the first rod body 11, or directly formed integrally with the first rod body 11, which can simplify the manufacturing process. It is understandable that, in addition to being arranged on the inner wall of the insertion end 111, the heat-conducting structure 4 can also be further arranged on the inner wall of other parts of the first rod body 11, as long as it can form an abutment with the first temperature sensor 2.
[0031] The wireless temperature probe provided by the embodiment of the utility model includes a needle body 1, a first temperature sensor 2, a battery 3 and a heat-conducting structure 4. The needle body 1 includes a first rod body 11 inserted into the object to be processed, the first temperature sensor 2 is located at the insertion end 111 of the first rod body 11 and is electrically connected to the battery 3, and the heat-conducting structure 4 is at least arranged on the inner wall of the insertion end 111 and directly abuts against the first temperature sensor 2. By adopting the above design, the heat-conducting structure 4 reduces the gap between the inner wall of the first rod body 11 and the first temperature sensor 2, has a good limiting effect on the first temperature sensor 2, can effectively prevent the first temperature sensor 2 from loosening, ensure the connection reliability of the first temperature sensor 2, and make the first temperature sensor 2 always maintain physical contact with the inner wall of the first rod body 11, thereby maintaining stable contact heat transfer, and can more accurately and timely detect the temperature of the object to be processed through the first rod body 11, effectively improving the accuracy of the wireless temperature probe in detecting temperature.
[0032] In some embodiments, Figure 2As shown, the heat-conducting structure 4 is a heat-conducting block arranged on a part of the inner wall of the insertion end 111, and an accommodation space 41 is formed between the heat-conducting block and the inner wall of the opposite insertion end 111, and the first temperature sensor 2 is arranged in the accommodation space 41. Among them, the heat-conducting block abuts against one side of the first temperature sensor 2, and the other side of the first temperature sensor 2 directly abuts against the inner wall of the insertion end 111. The above embodiment adopts the heat-conducting structure 4 and the inner wall of the insertion end 111 to jointly contact and limit the first temperature sensor 2. The heat-conducting structure 4 can be only one, or multiple heat-conducting structures 4 can be arranged on the same side of the first temperature sensor 2. In this way, the heat-conducting structure 4 is only squeezed on one side of the first temperature sensor 2, and the other side of the first temperature sensor 2 abuts against the inner wall of the insertion end 111, so that the contact heat transfer between the first temperature sensor 2 and the inner wall of the insertion end 111 can be effectively maintained.
[0033] In some embodiments, Figure 3 As shown, multiple heat-conducting structures 4 are arranged at intervals, and the first temperature sensor 2 is arranged between each heat-conducting structure 4. The above embodiment adopts multiple heat-conducting structures 4 to jointly contact and limit the first temperature sensor 2. Multiple heat-conducting structures 4 need to be arranged, and the first temperature sensor 2 is clamped between each heat-conducting structure 4. When designed in this way, the first temperature sensor 2 indirectly contacts the inner wall of the insertion end 111 by abutting the heat-conducting structure 4, and can also effectively maintain the contact heat transfer between the first temperature sensor 2 and the inner wall of the insertion end 111. At the same time, multiple heat-conducting structures 4 can form multi-point contact with the first temperature sensor 2, provide an effective limiting effect, prevent the first temperature sensor 2 from shaking when subjected to external impact, and improve the stability of the first temperature sensor 2.
[0034] In some embodiments, Figure 4 and Figure 5 As shown, the heat-conducting structure 4 is a heat-conducting block continuously arranged around the inner wall of the insertion end 111, and a receiving cavity 42 is formed on the heat-conducting block. The first temperature sensor 2 is arranged in the receiving cavity 42. Among them, in the cross section cut along the axis of the first rod body 11, as shown in FIG. Figure 4 As shown, the cross-sectional shape of the accommodation cavity 42 is the same as the cross-sectional shape of the first temperature sensor 2, or as shown in FIG. Figure 5 As shown, the cross-sectional shape of the accommodating cavity 42 is "expanded". Specifically, the heat-conducting structure 4 in the above embodiment is an integrated structure surrounding the inner wall of the insertion end 111, for example, it can be a rotating body structure such as a cylinder or a truncated cone. The accommodating cavity 42 formed on the heat-conducting structure 4 is used to accommodate the first temperature sensor 2, and the side wall of the accommodating cavity 42 abuts against the first temperature sensor 2, so as to achieve stable contact heat transfer. Optionally, there are multiple design schemes for the shape of the accommodating cavity 42, for example, Figure 4As shown, the cross-sectional shape of the accommodating cavity 42 can be designed to be the same as the cross-sectional shape of the first temperature sensor 2, so that the space of the accommodating cavity 42 can better adapt to the shape of the first temperature sensor 2, so that the first temperature sensor 2 can fully fit the side wall of the accommodating cavity 42, ensuring continuous contact and heat transfer between the first temperature sensor 2 and the heat-conducting structure 4; for another example, Figure 5 As shown, the cross-sectional shape of the accommodating cavity 42 is "expanded", that is, the radial dimension of the accommodating cavity 42 gradually increases from the bottom to the opening, so that when the first temperature sensor 2 is placed in the accommodating cavity 42, it can be stuck in the middle of the accommodating cavity 42, which has a good fixing effect and also ensures continuous contact and heat transfer between the first temperature sensor 2 and the heat-conducting structure 4.
[0035] In some embodiments, Figure 1 As shown, the wireless temperature probe also includes a battery limiter 31, which is arranged on the inner wall of the first rod body 11, and at least one battery limiter 31 is arranged. When only one battery limiter 31 is arranged, the battery 3 is clamped between the battery limiter 31 and the inner wall of the first rod body 11. When multiple battery limiters 31 are arranged, the battery 3 is at least clamped between two opposite battery limiters 31. In the above embodiment, the limiting effect of the battery limiter 31 and the inner wall of the first rod body 11 on the battery 3 is similar to the limiting effect of the above-mentioned heat-conducting structure 4 and the inner wall of the insertion end 111 on the first temperature sensor 2, that is, both sides of the battery 3 are abutted at the same time, thereby limiting the movement of the battery 3. Through such a design, the reliability of the connection of the battery 3 can be guaranteed, and the problem of poor contact caused by the loosening of the battery 3 can be avoided to the greatest extent.
[0036] In some embodiments, Figure 1As shown, the wireless temperature probe also includes a circuit board 5 and a connecting wire 6. The circuit board 5 is at least partially arranged in the first rod body 11 and connected to the first temperature sensor 2. The circuit board 5 is at least used to process and output the temperature data detected by the first temperature sensor 2. The connecting wire 6 is connected between the first temperature sensor 2 and the circuit board 5, and the connecting wire 6 has a bending portion 61, and the bending portion 61 has a tendency to return to a straight line, thereby generating a certain elastic force, which can push the first temperature sensor 2 to abut against the heat-conducting structure 4. Optionally, the circuit board 5 can be partially arranged in the first rod body 11, or it can be completely arranged in the first rod body 11. When the circuit board 5 is completely arranged in the first rod body 11, since the ambient temperature of the first rod body 11 is usually lower than the ambient temperature of the second rod body 12, the heat resistance requirements of the circuit board 5 are relatively low, which can reduce the manufacturing cost caused by the heat insulation treatment of the circuit board 5 to a certain extent. In the above embodiment, the connecting wire 6 is used to connect the first temperature sensor 2 with the circuit board 5, so as to realize the transmission of temperature data. After the circuit board 5 processes the temperature data, it can output relevant information to the user's mobile phone and other signal receiving terminals through wireless communication technologies such as Bluetooth. At the same time, the curved portion 61 of the connecting wire 6 can continuously apply elastic force to the first temperature sensor 2, squeezing the first temperature sensor 2 toward the insertion end 111, so that the first temperature sensor 2 can be more closely abutted against the thermal conductive structure 4 to ensure the stability of contact heat transfer.
[0037] In some embodiments, Figure 1 As shown, the wireless temperature probe also includes a signal transmission antenna 7 and an antenna stopper 71. The signal transmission antenna 7 is at least partially disposed in the second rod body 12 and is connected to the circuit board 5 to transmit data processed by the circuit board 5 to the signal receiving terminal. The antenna stopper 71 is disposed on the inner wall of the second rod body 12 and abuts against the signal transmission antenna 7 to limit the position of the signal transmission antenna 7. In the above design, the signal transmission antenna 7 is used to realize radio communication, which can enhance the stability of data interaction and increase the communication distance. At the same time, by using the antenna stopper 71 to limit the signal transmission antenna 7, the stability of the connection between the signal transmission antenna 7 and the circuit board 5 can be increased, and the signal transmission antenna 7 can be effectively prevented from loosening.
[0038] In some embodiments, Figure 1As shown, the wireless temperature probe also includes a second temperature sensor 8, which is disposed in the second rod body 12 and connected to the circuit board 5. Specifically, the second temperature sensor 8 is exposed to the outside of the object to be processed along with the second rod body 12, and is mainly used to detect the temperature inside the food processing equipment, thereby monitoring the set temperature of the food processing equipment. In this way, on the basis of the first temperature sensor 2 monitoring the temperature of the object to be processed, the range of temperature monitoring is further increased, and more relevant information about food processing can be provided to the user, so as to better control the quality of food processing. Optionally, when the second temperature sensor 8 is provided, the above-mentioned heat-conducting structure 4 can also be provided on the inner wall of the second rod body 12 adjacent to the second temperature sensor 8, so as to maintain stable contact heat transfer between the second temperature sensor 8 and the inner wall of the second rod body 12, thereby improving the accuracy of the second temperature sensor 8 in detecting the temperature.
[0039] In some embodiments, Figure 1 As shown, the wireless temperature probe also includes a wireless charging control component 91, which is disposed in the first rod body 11 and is at least connected to the battery 3 to at least charge the battery 3. Optionally, in addition to being connected to the battery 3, the wireless charging control component 91 can also be connected to the circuit board 5 at the same time to transmit data such as the charging progress of the battery 3 to the circuit board 5 during the charging process, and output the data through the circuit board 5. Furthermore, the wireless charging control component 91 can also be used to detect the charging in place state, or control the battery 3 to stop supplying power to components such as the first temperature sensor 2 when charging starts, so as to ensure the efficiency and stability of wireless charging. The above-mentioned embodiment uses the wireless charging control component 91 to enable the wireless temperature probe to achieve wireless charging. In this way, the wireless temperature probe does not need to be provided with exposed charging contacts, charging ports or wires, etc., which can better avoid the problem of electrostatic discharge of exposed electrodes and improve the waterproof and moisture-proof performance of the circuit. At the same time, the wireless charging control component 91 is arranged in the first rod body 11. Similar to the above-mentioned circuit board 5, this arrangement has relatively low requirements on the heat resistance of the wireless charging control component 91, which can reduce the manufacturing cost caused by the heat insulation treatment to a certain extent.
[0040] In some embodiments, Figure 1As shown, the wireless temperature probe also includes a charging coil 92, which is arranged in the second rod body 12 and connected to the wireless charging control component 91. The charging coil 92 is used to obtain electrical energy through electromagnetic induction and transmit electrical energy to the wireless charging control component 91. Specifically, the charging coil 92 is an important component for realizing wireless charging. It uses the principle of electromagnetic induction to generate induced electromotive force and induced current when the environmental electromagnetic field changes. It only needs to be provided with a power supply coil and other structures compatible with the charging coil 92 on the charging device corresponding to the wireless temperature probe to realize wireless charging. Therefore, the charging method of the wireless temperature probe provided in the embodiment of the utility model can be wired charging, magnetic contact charging or wireless charging, and the configuration is relatively flexible. When the wireless charging method is adopted, the charging coil 92 can be enclosed in the second rod body 12 without being exposed, and has good waterproof and moisture-proof performance.

Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
