The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0032] This embodiment provides a food temperature probe.

[0033] Please refer to Figure 1-5 The food temperature probe includes a probe body 100, a first temperature measuring component 200, a control circuit board 300, a second temperature measuring component 400 and a barrier structure 500. The probe body 100 has a high temperature zone 110, a low temperature zone 120 and a safety line 130, and the safety line 130 is located between the high temperature zone 110 and the low temperature zone 120. The probe body 100 has a wire hole 140 inside, and the wire hole 140 connects the high temperature zone 110 and the low temperature zone 120. The first temperature measuring component 200 is arranged in the low temperature zone 120 of the probe body 100, and the control circuit board 300 is arranged in the low temperature zone 120 of the probe body 100, and is electrically connected to the first temperature measuring component 200. The second temperature measuring component 400 is arranged in the high temperature zone 110 of the probe body 100, and the second temperature measuring component 400 has a connecting line 410, and the connecting line 410 extends from the wire hole 140 to the low temperature zone 120, and is electrically connected to the control circuit board 300. A blocking structure 500 is disposed at least around the wire hole 140 to seal the gap between the connecting wire 410 and the wire hole 140 .

[0034] When using the food temperature probe, the user can use the first temperature measuring member 200 located in the low temperature zone 120 to measure an object or environment with a lower temperature, for example, it can be used to measure the temperature of the center of the food. And the user can use the second temperature measuring member 400 located in the high temperature zone 110 to measure an object or environment with a higher temperature, for example, it can be used to measure the ambient temperature of the oven. On the one hand, due to the addition of the barrier structure 500, the gap between the connecting wire 410 and the wire hole 140 is sealed by the barrier structure 500, so that when the food temperature probe is used or cleaned, after external moisture penetrates into the high temperature zone 110, it cannot flow into the low temperature zone 120 through the wire hole 140, thereby helping to avoid the control circuit board 300 in the low temperature zone 120 from malfunctioning due to water ingress. On the other hand, since the wire hole 140 is not a hardware connection, the barrier structure 500 used to seal the wire hole 140 is not easily affected by external impact force, thereby helping to reduce the risk of cracking of the barrier structure 500 under external impact.

[0035] Please refer to Figure 1 , 4 5. In one embodiment, the probe body 100 includes a first tube body 150, a second tube body 160, a handle 170 and a heat insulating member 180. The first tube body 150 and the second tube body 160 are respectively sleeved at opposite ends of the heat insulating member 180. The safety line 130 is located on the side wall of the heat insulating member 180 and separates the first tube body 150 and the second tube body 160. The handle 170 is sleeved at one end of the second tube body 160 away from the safety line 130. The handle 170 and the second tube body 160 form a high temperature zone 110, and the first tube body 150 forms a low temperature zone 120. The wire hole 140 passes through the opposite ends of the heat insulating member 180 to connect the space in the first tube body 150 with the space in the second tube body 160. The barrier structure 500 includes a first structure layer 510 . The first structure layer 510 fills the end of the heat insulating member 180 having the wire through hole 140 to seal the gap between the connecting wire 410 and the wire through hole 140 .

[0036] On the one hand, the probe body 100 is formed by the first tube body 150, the second tube body 160, the handle 170 and the heat insulating member 180, wherein the first tube body 150 forms the low temperature zone 120, the handle 170 and the second tube body 160 form the high temperature zone 110, and the heat insulating member 180 plays a role in blocking the heat transfer between the low temperature zone 120 and the high temperature zone 110. On the other hand, the end of the heat insulating member 180 with the wire hole 140 is filled with the first structural layer 510 to achieve the purpose of sealing the gap between the connecting wire 410 and the wire hole 140, so as to prevent the liquid from flowing from the high temperature zone 110 to the low temperature zone 120 through the gap, thereby reducing the risk of functional failure of the control circuit board 300 in the low temperature zone 120 due to water ingress. Specifically, the first structural layer 510 can be selected from a high temperature structural adhesive layer, or other adhesive layers or sealing material layers that can play a sealing role, such as a heat-resistant plastic layer.

[0037] Please refer to Figure 1 , 4 and 5. In one embodiment, the end of the heat insulating member 180 located in the second tube body 160 has a groove 181, the wire hole 140 is located in the groove 181, and the first structural layer 510 fills the groove 181.

[0038] Since the wire hole 140 is opened in the groove 181, on the one hand, when the first structural layer 510 is a glue layer, it is convenient to inject glue into the groove 181 and shape it, so that the first structural layer 510 fills the groove 181. On the other hand, after the first structural layer 510 fills the groove 181, the first structural layer 510 seals the gap between the wire hole 140 in the groove 181 and the connecting wire 410, thereby preventing the liquid in the high temperature area 110 from flowing to the low temperature area 120 through the gap. Of course, in other embodiments, the thermal insulation member 180 may not have the groove 181, but directly open the wire hole 140 on the end surface of the thermal insulation member 180.

[0039] Please refer to Figure 1 , 4 In one embodiment, the heat insulating member 180 is provided with a plurality of wire holes 140, and the connecting wires 410 are configured in plurality, and the plurality of connecting wires 410 respectively extend from the high temperature zone 110 to the low temperature zone 120 through the plurality of wire holes 140. The first structural layer 510 fills the end of the heat insulating member 180 having the plurality of wire holes 140 to seal the gap between the plurality of connecting wires 410 and the plurality of wire holes 140.

[0040] On the one hand, since a plurality of wire holes 140 are provided on the heat insulating member 180, a plurality of connecting wires 410 can extend from the high temperature zone 110 to the low temperature zone 120 through the corresponding wire holes 140, respectively, so as to meet the more complex circuit connection requirements between the second temperature measuring member 400 and the control circuit board 300. On the other hand, the first structural layer 510 can simultaneously seal the gaps between the plurality of connecting wires 410 and the plurality of wire holes 140, thereby improving the utilization rate of the first structural layer 510.

[0041] Please refer to Figure 1-3 In one embodiment, the barrier structure 500 further includes a second structural layer 520, and the second structural layer 520 is provided between the thermal insulation 180 and the inner wall of the first tube body 150 to seal the gap between the thermal insulation 180 and the inner wall of the first tube body 150. The second structural layer 520 is provided between the thermal insulation 180 and the inner wall of the second tube body 160 to seal the gap between the thermal insulation 180 and the inner wall of the second tube body 160.

[0042] Due to the addition of the second structural layer 520, the gap between the thermal insulation 180 and the inner wall of the first tube body 150 and the inner wall of the second tube body 160 is sealed by the second structural layer 520. On the one hand, it can prevent liquid from entering the low temperature zone 120 from the gap between the thermal insulation 180 and the inner wall of the first tube body 150, and it can also prevent liquid from entering the high temperature zone 110 from the gap between the thermal insulation 180 and the inner wall of the second tube body 160, which is conducive to further enhancing the waterproof performance of the probe body 100. On the other hand, it is also conducive to improving the stability of the connection between the first tube body 150, the second tube body 160 and the thermal insulation 180. Specifically, the thermal insulation 180 can be made of insulating ceramics, insulating glass or other suitable insulating materials. The second structural layer 520 can be made of a high temperature structural adhesive layer, or other adhesive layers or sealing material layers that can play a sealing role, such as a heat-resistant plastic layer.

[0043] Please refer to Figure 1-3 In one embodiment, the barrier structure 500 further includes a third structural layer 530 , which is disposed between the inner wall of the handle 170 and the outer wall of the second tube body 160 to seal the gap between the inner wall of the handle 170 and the outer wall of the second tube body 160 .

[0044] Since the third structural layer 530 is added, the gap between the inner wall of the handle 170 and the outer wall of the second tube body 160 is sealed by the third structural layer 530 to prevent liquid from entering the high temperature zone 110 from the gap between the inner wall of the handle 170 and the outer wall of the second tube body 160 when the food temperature probe is used or cleaned, which is conducive to further enhancing the waterproof performance of the probe body 100. Specifically, the handle 170 can be made of ceramic, glass or other suitable materials. The third structural layer 530 can be made of a high-temperature structural adhesive layer, or other adhesive layers or sealing material layers that can play a sealing role, such as a heat-resistant plastic layer.

[0045] Please refer to Figure 1-3 In one embodiment, the barrier structure 500 further includes a sealing ring 540 , and the side wall of the thermal insulation member 180 has a mounting groove 182 , and the sealing ring 540 is mounted in the mounting groove 182 .

[0046] On the one hand, the sealing ring 540 is stably installed on the side wall of the heat insulating member 180 through the cooperation between the sealing ring 540 and the mounting groove 182. On the other hand, the sealing ring 540 further seals the gap between the side wall of the heat insulating member 180 and the first tube body 150 and / or the second tube body 160, which is conducive to further improving the waterproof performance of the probe body 100.

[0047] Please refer to Figure 1-3 In one embodiment, the side wall of the heat insulating member 180 located in the first tube body 150 has a first installation groove 1821, and the side wall of the heat insulating member 180 located in the second tube body 160 has a second installation groove 1822. The sealing ring 540 includes a first sealing ring 541 and a second sealing ring 542. The first sealing ring 541 is installed in the first installation groove 1821 to seal the gap between the side wall of the heat insulating member 180 and the inner wall of the first tube body 150. The second sealing ring 542 is installed in the second installation groove 1822 to seal the gap between the side wall of the heat insulating member 180 and the inner wall of the second tube body 160.

[0048] On the one hand, the first sealing ring 541 is positioned on the side wall of the heat insulating member 180 located in the first tube body 150 through the first installation groove 1821, and the second sealing ring 542 is positioned on the side wall of the heat insulating member 180 located in the second tube body 160 through the second installation groove 1822, thereby realizing the installation of the first sealing ring 541 and the second sealing ring 542 on the heat insulating member 180. On the other hand, the gap between the side wall of the heat insulating member 180 and the inner wall of the first tube body 150 is sealed by the first sealing ring 541, and the gap between the side wall of the heat insulating member 180 and the inner wall of the second tube body 160 is sealed by the second sealing ring 542, which is conducive to further improving the waterproof performance of the probe body 100. Of course, in other embodiments, the first sealing ring 541 or the second sealing ring 542 can also be set only on the heat insulating member 180.

[0049] Please refer to Figure 1-5 In one embodiment, the probe body 100 includes a first tube body 150, a second tube body 160, a handle 170 and a safety line 130. The first tube body 150 and the second tube body 160 are respectively located on opposite sides of the safety line 130, and the handle 170 is sleeved on an end of the second tube body 160 away from the safety line 130. The handle 170 and the second tube body 160 form a high temperature zone 110, and the first tube body 150 forms a low temperature zone 120. The barrier structure 500 includes a first structural layer 510, which is disposed in the high temperature zone 110 to seal the gap between the connecting line 410 and the wire hole 140.

[0050] On the one hand, the probe body 100 is formed by the first tube body 150, the second tube body 160, the handle 170 and the heat insulating member 180, wherein the first tube body 150 forms the low temperature zone 120, the handle 170 and the second tube body 160 form the high temperature zone 110, and the safety line 130 serves to separate the high temperature zone 110 from the low temperature zone 120. On the other hand, the end of the heat insulating member 180 with the wire hole 140 is filled with the first structural layer 510 to achieve the purpose of sealing the gap between the connecting wire 410 and the wire hole 140, thereby preventing the liquid from flowing from the high temperature zone 110 to the low temperature zone 120 through the gap, thereby reducing the risk of functional failure of the control circuit board 300 in the low temperature zone 120 due to water ingress. It should be noted that the safety line 130 can be set on the side wall of the heat insulating member 180, or it can be configured as an independent component.

[0051] Please refer to Figure 1-3 In one embodiment, the first tube body 150 has an insertion portion 151 at one end away from the safety line 130 , and the radial dimension of the insertion portion 151 gradually increases in a direction approaching the safety line 130 .

[0052] The insertion portion 151 is roughly conical. When the user needs to insert the first tube body 150 into food to measure the internal temperature of the food, the shape of the insertion portion 151 can be more easily inserted into the food, thereby helping to improve the user experience.

[0053] Please refer to Figure 1-3 In one embodiment, the safety line 130 is protruded from the side wall of the heat insulating member 180 and surrounds the heat insulating member 180 along the circumference. The end of the first tube 150 and the end of the second tube 160 respectively contact the two opposite side walls of the safety line 130.

[0054] Since the safety line 130 is arranged on the side wall of the heat insulating member 180, on the one hand, when the assembler installs the first tube body 150 and the second tube body 160 at the opposite ends of the heat insulating member 180, the safety line 130 is naturally exposed to the first tube body 150 and the second tube body 160, so as to play the role of separating the high temperature area 110 and the low temperature area 120 on the surface of the probe body 100. On the other hand, the number of parts that the assembler needs to assemble is reduced, which is conducive to improving the work efficiency of the assembler. Of course, in other embodiments, the safety line 130 may not be combined with the heat insulating member 180, but exist as an independent component.

[0055] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
