[0040] Figure 1 A cross-sectional view of an embodiment of the temperature probe of the utility model; Figure 2 This is a schematic structural diagram of an embodiment of the temperature probe of the utility model; Figure 3 It is an exploded schematic diagram of an embodiment of the temperature probe of the utility model; Figure 4 The schematic diagram of the structure of the second connecting member of an embodiment of the temperature probe of the present utility model is shown in FIG. In the embodiment of the present utility model, the temperature probe 100 includes a circuit board 110 , a sealing assembly 120 , a first housing 130 and a second housing 140 .

[0041] The sealing assembly 120 includes a high temperature resistant elastic material, and one end of the first housing 130 has a probe portion 131, and the other end has a protruding first connection portion 132. One end of the second housing 140 is connected to the first connection portion 132, and the first housing 130 and the second housing 140 are connected to each other to form a closed chamber A1, so that the circuit board 110 is in the closed chamber A1. At least part of the sealing assembly 120 is located at the connection between the first housing 130 and the second housing 140, so that the closed chamber A1 is isolated from the outside.

[0042] In this embodiment, at least part of the sealing assembly 120 is disposed at the connection between the first housing 130 and the second housing 140, so that the sealed chamber A1 formed by the first housing 130 and the second housing 140 is isolated from the outside, thereby ensuring the airtightness of the temperature probe 100. The probe portion 131 of the first housing 130 is used to allow the temperature probe 100 to be easily inserted into the food.

[0043] The temperature probe 100 further includes a temperature measuring assembly 160, which includes a first temperature sensor 161 and a second temperature sensor 162. The first temperature sensor 161 is disposed in a sealed chamber A1 located in the probe portion 131 and is electrically connected to the circuit board 110, and the second temperature sensor 162 is disposed in a sealed chamber A1 located in the second housing 140 and is electrically connected to the circuit board 110. The first temperature sensor 161 is used to detect the internal temperature of the food and generate the first temperature information, and the second temperature sensor 162 is used to detect the external temperature of the food and generate the second temperature information. The circuit board 110 includes a communication module, which can transmit the first temperature information and the second temperature information to the outside.

[0044] Furthermore, the first housing 130 of this embodiment is made of metal material, and the second housing 140 is made of metal material and / or non-metal material. When the temperature probe 100 detects the temperature of food, the portion of the first housing 130 made of metal material extends into the food, and the portion of the second housing 140 is located outside.

[0045] The first housing 130 and the second housing 140 are connected by a threaded structure. The metal material includes stainless steel, and the non-metal material includes ceramic material, such as zirconium oxide or aluminum oxide. When the first housing 130 of the temperature probe 100 partially extends into the food, the stainless steel material can prevent the temperature probe 100 from rusting.

[0046] The temperature probe 100 provided by the embodiment of the utility model sets the circuit board 110 in the closed chamber A1, and seals the first shell 130 and the second shell 140 of the temperature probe 100, so that the circuit board 110 is isolated from the external environment and external liquid is prevented from flowing into the closed chamber A1. At the same time, the shell of the temperature probe 100 can also protect the circuit board 110 and prevent the circuit board 110 from being damaged by high temperature, thereby improving the waterproof performance and high temperature resistance performance of the temperature probe 100.

[0047] In some embodiments, the second shell 140 includes a first connecting member 141, a second connecting member 142, and a connecting handle 143. One end of the second connecting member 142 has a protruding second connecting portion 1421, and the other end has a protruding third connecting portion 1422. One end of the first connecting member 141 is connected to the first connecting portion 132, and the other end is connected to the second connecting portion 1421. One end of the connecting handle 143 is connected to the third connecting portion 1422.

[0048] In this embodiment, the first connecting member 141, the second connecting member 142 and the connecting handle 143 can be made of metal material or non-metal material, and the non-metal material includes ceramic material. Preferably, the first connecting member 141 and the connecting handle 143 are made of ceramic material aluminum oxide or zirconium oxide, and the connecting handle 143 is in the shape of a handle so that the user can hold the temperature probe 100. The second connecting member 142 is made of metal material, and optionally, the second connecting member 142 is made of stainless steel material. The second connecting portion 1421 and the third connecting portion 1422 at both ends of the second connecting member 142 are respectively connected to the first connecting member 141 and the connecting handle 143 to form the second housing 140.

[0049] Further, the surfaces of the first connection part 132, the second connection part 1421 and the third connection part 1422 have threaded mating parts, one end of the first connection member 141 is connected to the first housing 130 through the first connection part 132, and the other end is connected to the second connection member 142 through the second connection part 1421, and one end of the connection handle 143 is connected to the second connection member 142 through the third connection part 1422. The first housing 130, the first connection member 141, the second connection member 142 and the connection handle 143 are connected by the threaded structure, which facilitates the assembly of the temperature probe 100. Since the second connection member 142 is made of metal material, the stability of the connection between the first connection member 141 and the connection handle 143 can be improved, thereby ensuring the overall structural strength of the temperature probe 100.

[0050] In some embodiments, the sealing assembly 120 includes two first sealing members 121, the surface of the second connecting member 142 facing the first connecting member 141 has a first sealing groove 1423, the surface of the second connecting member 142 facing the connecting handle 143 has a second sealing groove 1424, and the two first sealing members 121 are respectively arranged in the first sealing groove 1423 and the second sealing groove 1424; the first sealing member 121 located in the first sealing groove 1423 abuts against the first connecting member 141 and the second connecting member 142, respectively, and the first sealing member 121 located in the second sealing groove 1424 abuts against the connecting handle 143 and the second connecting member 142, respectively.

[0051] In this embodiment, the first sealing groove 1423 is annular and surrounds the closed chamber A1, and the shape of the first sealing member 121 matches the shape of the first sealing groove 1423. The two first sealing members 121 are matched with the first sealing groove 1423 and the second sealing groove 1424 respectively. When the first sealing member 121 is embedded in the first sealing groove 1423 and the second sealing groove 1424, it slightly protrudes from the notches of the first sealing groove 1423 and the second sealing groove 1424, so that when the two ends of the second connecting member 142 are connected with the first connecting member 141 and the connecting handle 143 respectively, interference fit can be achieved, ensuring that the first sealing member 121 can seal the connection between the second connecting member 142 and the first connecting member 141 and the connecting handle 143.

[0052] In some embodiments, the sealing assembly 120 also includes a second seal 122, which is disposed in the closed chamber A1; the first end 1221 of the second seal 122 abuts against the inner wall surface of the first shell 130, and the second end 1222 of the second seal 122 abuts against the inner wall surface of the first connecting member 141, and the shape of the first end 1221 matches the inner wall surface of the first shell 130, and the shape of the second end 1222 matches the inner wall surface of the first connecting member 141.

[0053] In this embodiment, the second sealing member 122 can be set to a high-temperature resistant silicone rubber material. The first end 1221 of the second sealing member 122 is located in the first shell 130, and the second end 1222 is located in the first connecting member 141. The outer peripheral surface of the first end 1221 abuts against the inner wall surface of the first shell 130, and the outer peripheral surface of the second end 1222 abuts against the inner wall surface of the first connecting member 141, so that the second sealing member 122 can seal the connection between the first shell 130 and the first connecting member 141.

[0054] In some embodiments, the sealing assembly 120 also includes a third seal 123, which is disposed in the closed chamber A1 and located at one end of the second seal 122 close to the probe portion 131. The outer peripheral surface of the third seal 123 abuts against the inner wall surface of the first shell 130 and is spaced from the second seal 122.

[0055] In this embodiment, the third seal 123 can be set to a high-temperature resistant silicone rubber material, the outer peripheral surface of the third seal 123 abuts against the inner wall surface of the first shell 130, and the circuit board 110 is passed through the third seal 123 and the second seal 122, so that a closed gap is formed between the third seal 123 and the second seal 122, and the gap is used to fill with waterproof material to form a first sealing layer 124 to improve the waterproof performance of the temperature probe 100.

[0056] In the embodiment of the utility model, the first sealing member 121, the second sealing member 122 and the third sealing member 123 are made of high temperature resistant elastic material, which may be high temperature resistant silicone rubber, high temperature resistant fluororubber or other polymer materials.

[0057] Figure 6 For this utility model Figure 3 In some embodiments, a first sealing layer 124 is provided between the third sealing member 123 and the second sealing member 122, so that the sealed chamber A1 of the third sealing member 123 close to the probe portion 131 is isolated from the outside.

[0058] In this embodiment, the first sealing layer 124 is set to a waterproof material, and the waterproof material includes a high temperature resistant waterproof glue and the like. Through the sealing effect of the third sealing member 123, when the waterproof material is injected, the high temperature resistant waterproof glue can be prevented from leaking, so that the waterproof material forms the first sealing layer 124. In addition, the second sealing member 122, the first sealing layer 124 and the third sealing member 123 form a triple protection, which improves the waterproof performance of the temperature probe 100. In addition, the second sealing member 122, the first sealing layer 124 and the third sealing member 123 all include high temperature resistant materials, which can also ensure the stability of the waterproof performance when the temperature probe 100 is in a high temperature environment.

[0059] Furthermore, the first sealing layer 124 is obtained by curing a sealant layer, wherein the sealant layer includes aluminum oxide and alcohol, wherein the sealant layer includes a structural adhesive of a metal alkoxide adhesive type.

[0060] In some embodiments, the outer circumferential surfaces of the first connection part 132, the second connection part 1421, and the third connection part 1422 have a threaded mating part, and the surface of the threaded mating part has a second sealing layer 125, so that the first shell 130 is tightly connected to the first connection member 141, the first connection member 141 is tightly connected to the second connection member 142, and the second connection member 142 is tightly connected to the connection handle 143; the end of the third connection part 1422 has a sealing structure 126, so that the closed chamber A1 located at the connection handle 143 is isolated from the outside.

[0061] In this embodiment, the threaded mating parts of the second sealing layer 125 located on the surfaces of the first connection part 132, the second connection part 1421, and the third connection part 1422 are meshed with the threaded structures of the inner wall surfaces of the first shell 130, the first connection member 141, and the second connection member 142 for easy installation and connection. The second sealing layer 125 is preferably a high temperature resistant waterproof glue. When the first shell 130, the first connection member 141, the second connection member 142, and the connecting handle 143 are connected to each other, the second sealing layer 125 can fill the gaps between the first connection part 132 and the inner wall surface of the first connection member 141, the second connection part 1421 and the inner wall surface of the first connection member 141, and the third connection part 1422 and the inner wall surface of the connecting handle 143, and increase the friction force. While improving the waterproof performance of the temperature probe 100, it can also make the components tightly connected and cannot be easily separated, thereby improving the structural strength of the temperature probe 100.

[0062] Furthermore, the sealing structure 126 at the end of the third connecting part 1422 can be a sealing plug or a sealing layer having a high-temperature resistant and waterproof adhesive material. The sealing plug isolates the closed chamber A1 on the side of the third connecting part 1422 close to the connecting handle 143 from the third connecting part 1422, and cooperates with the second sealing layer 125 of the third connecting part 1422 to improve the airtightness of the connection between the third connecting part 1422 and the connecting handle 143.

[0063] Specifically, the second sealing layer 125 is obtained by curing a sealant layer, wherein the sealant layer includes aluminum oxide and alcohol, wherein the sealant layer includes a structural adhesive of a metal alkoxide adhesive type.

[0064] In some embodiments, the first shell 130, the first connecting member 141, the second connecting member 142, and the connecting handle 143 are hollow structures. When the first shell 130, the first connecting member 141, the second connecting member 142, and the connecting handle 143 are connected to each other, the first shell 130, the first connecting member 141, the second connecting member 142, and the connecting handle 143 are connected to form a closed chamber A1.

[0065] In this embodiment, the first shell 130, the first connecting member 141, the second connecting member 142 and the connecting handle 143 all include chambers. When the first shell 130, the first connecting member 141, the second connecting member 142 and the connecting handle 143 are connected to each other, the chambers of the first shell 130, the first connecting member 141, the second connecting member 142 and the connecting handle 143 are interconnected to form a closed chamber A1, so that the circuit board 110 can be placed in the closed chamber A1 to protect the circuit board 110.

[0068] The first electrode 111 and the second electrode 112 can be electrically connected to an external power source, and the external power source can supply power to the power storage element 150 through the first electrode 111 and the second electrode 112 .

[0069] Furthermore, the external power supply can supply power to the energy storage element 150 by wireless charging through magnetic induction with the first electrode 111 and the second electrode 112, or the temperature probe 100 also includes a charging port, and the external power supply is electrically connected to the first electrode 111 and the second electrode 112 through the charging port and supplies power to the energy storage element 150.

At the same time, the shell of the temperature probe 100 can also protect the circuit board 110 to prevent the circuit board 110 from being damaged by high temperature, thereby improving the waterproof performance and high temperature resistance performance of the temperature probe 100, so that the temperature detection device can avoid the problem of being unable to detect temperature in a high temperature and high humidity environment due to insufficient protection of the temperature probe 100.
