Description

Technical Field

[0001] The present application relates to the field of food cooking, and in particular to an insertion temperature probe for detecting the temperature of food. Background Art

[0002] With the advancement of technology and the increasing requirements of people on the taste and nutrition of food, people expect to control the temperature of the cooking process more accurately, such as more accurately controlling the temperature of the food and the temperature of the water used to heat the food. Therefore, a temperature detection device used in food cooking came into being.

[0003] Insertion temperature probes are a type of temperature detection device that can be inserted into the food during cooking to detect the temperature of various parts of the food. They are also called handheld temperature probes, handheld thermometers, food probes, etc. In order to achieve more portable use, this insertion temperature probe can be powered by a built-in rechargeable battery, which requires the probe to have a charging function so that the rechargeable battery can be charged when the power supply battery is exhausted. However, the current charging structure of the insertion temperature probe is relatively complicated, which is not conducive to the miniaturization or small diameter design of the probe.

[0052] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0053] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0054] The present application provides an insertion temperature probe (also referred to as a temperature probe for short), which can be inserted into food during or after cooking to detect the temperature inside the food.

[0055] Specifically, the insertion temperature probe can be inserted into the food during the cooking process to detect the temperature inside the food, especially to obtain the lowest temperature inside the food as accurately as possible. The food can be in any cooking space, including but not limited to: steaming, boiling, baking, roasting, frying, deep-frying, etc. or heat-treated by any other means.

[0056] Please refer to Figure 1-4 In some embodiments, the insertable temperature probe includes a housing 100, a control assembly 200, and an ambient temperature detection unit 300. Of course, when necessary, the temperature probe may also include other related components, which may refer to the temperature probe in the prior art.

[0057] The housing 100 is used to protect and install components that realize the functions of the probe (such as the ambient temperature detection unit 300, the food temperature detection unit 400 and / or other electronic components, etc.). The housing 100 includes a first cavity wall 110, an insulating member 120 and a second cavity wall 130. The first cavity wall 110 and the second cavity wall 130 are insulated and separated by the insulating member 120 to prevent a short circuit between the first cavity wall 110 and the second cavity wall 130. The insulating member 120 can be made of insulating ceramic or other insulating materials. The first cavity wall 110 and the second cavity wall 130 can be made of various existing materials that can conduct electricity and heat and can be used in a cooking environment, such as metal materials or other materials. The control component 200 is arranged in the housing 100. The control component 200 is used to realize the control of part or all functions of the probe, such as the control of the ambient temperature detection unit 300, the control of charging, and the control of the food temperature detection unit 400 described later. The control component 200 can use but is not limited to a control circuit board 210 with various functional circuits. Please refer to Fig.11 and 12 In some embodiments, the control circuit board 210 may have at least one chip including a main control chip 221 (MCU). In some embodiments, some functions may be controlled by separate chips, such as a communication chip or a chip with other functions in addition to the main control chip 221. Of course, in other embodiments, the communication function or other functions may also be integrated on a main control chip 221.

[0058] Please refer to Figure 2-4 The ambient temperature detection unit 300 is used to detect the ambient temperature of the cooking space and is disposed in the housing 100. Fig.11 In some embodiments, the control component 200 may have a temperature measurement circuit 222, and the temperature measurement circuit 222 is electrically connected to the main control chip 221. Fig.12 In some more specific embodiments, the temperature measurement circuit 222 may include a filter circuit 2221 and an operational amplifier circuit 2222. The filter circuit 2221 may be composed of, but not limited to, a resistor and a capacitor, a filter chip, or other structures. The ambient temperature detection unit 300 is electrically connected to the temperature measurement circuit 222 of the control component 200 through the first line 310 and the second line 320 to transmit the detected signal to the temperature measurement circuit 222.

[0059] During the cooking process, the temperature of the cooking space is usually much higher than the temperature inside the food (for example, the temperature in the oven can reach over 200°C, the temperature in the BBQ oven can reach over 500°C, etc.). Therefore, in some embodiments, the ambient temperature detection unit 300 may adopt a temperature detection unit that can operate at a higher temperature. For example, the ambient temperature detection unit 300 may adopt but is not limited to a thermocouple or other high temperature resistant temperature detection units.

[0060] Please refer to Fig.11 In some embodiments, the control component 200 has a charging circuit 223 (schematic diagram in the figure), and the charging circuit 223 is used to charge the rechargeable battery 600. Please refer to Fig.12 In some more specific embodiments, the charging circuit 223 includes an anti-backflow circuit 2231. The anti-backflow circuit 2231 may include but is not limited to a circuit composed of a diode, and may also be an anti-backflow circuit in other forms.

[0061] Please refer to Fig.12 In some embodiments, the charging circuit 223 has a positive terminal 2233 and a negative terminal 2234. In order to electrically connect the charging circuit 223 to an external charging device to achieve charging, in some embodiments, one of the positive terminal 2233 and the negative terminal 2234 is electrically connected to the first cavity wall 110, and the other is electrically connected to the second cavity wall 130 through the first line 310 and / or the second line 320, so that the inserted temperature probe can be charged through the first cavity wall 110 and the second cavity wall 130. That is, the first cavity wall 110 and the second cavity wall 130 are charged as two contacts of the charging circuit 223 and are electrically connected to an external charging device. The first cavity wall 110 can adopt various conductive structures to achieve conductive connection with one of the positive terminal 2233 and the negative terminal 2234. For example, please refer to Figure 2 In some embodiments, a conductive connector 211 may be provided on the control circuit board 210 of the control component 200, and the conductive connector 211 is electrically connected to the positive terminal 2233 or the negative terminal 2234 of the charging circuit 223, for example, by welding together or connecting through a conductive cable. At the same time, the conductive connector 211 also maintains a conductive connection with the first cavity wall 110, such as conductive contact or conductive fixation. In some embodiments, the conductive connector 211 may be, but is not limited to, a conductive spring, a conductive cable, or other conductive structures.

[0062] In the above embodiment, at least one of the first circuit 310 and the second circuit 320 of the ambient temperature detection unit 300 is used as a charging connection line for the positive or negative electrode, and there is no need to provide a separate charging connection line for the positive or negative electrode, which simplifies the internal structure of the probe and is conducive to the miniaturization design of the probe.

[0063] Please refer to Figure 5In some more specific embodiments, the insulating member 120 divides the inner cavity of the housing 100 into a first cavity 101 and a second cavity 102. A portion of the cavity wall of the first cavity 101 is a first cavity wall 110, which may be, but not limited to, the first cavity wall 110 and the insulating member 120 or other more components to form the first cavity 101. A portion of the cavity wall of the second cavity 102 is a second cavity wall 130, which may be, but not limited to, the second cavity wall 130 and the insulating member 120 or other more components to form the second cavity 102. The first cavity wall 110 and the second cavity wall 130 may be Figure 8 The tubular structure shown may also be a non-tubular structure in other embodiments, such as a block structure.

[0064] Please refer to Figure 2-5 In some more specific embodiments, the insertion temperature probe further includes at least one food temperature detection unit 400, which is used to detect the temperature of the target food and is disposed in the first cavity 101. The control assembly 200 is disposed in the first cavity 101 and is electrically connected to the food temperature detection unit 400. In addition to serving as the positive charging contact or the negative charging contact of the charging circuit 223, the first cavity wall 110 can also serve as a heat-conducting structure of the food temperature detection unit 400 to transfer the temperature of the food to the food temperature detection unit 400. Of course, in other embodiments, a heat-conducting structure may also be provided on the first cavity 101, and the temperature of the food is mainly transferred to the food temperature detection unit 400 through the heat-conducting structure.

[0065] The environment temperature detection unit 300 is disposed in the second cavity 102. In addition to serving as the positive charging contact or the negative charging contact of the charging circuit 223, the second cavity wall 130 can also serve as a heat-conducting structure of the environment temperature detection unit 300 to conduct the temperature of the cooking space to the environment temperature detection unit 300. Of course, in other embodiments, a heat-conducting structure can also be provided on the second cavity 102, and the temperature of the cooking space is mainly conducted to the environment temperature detection unit 300 through the heat-conducting structure.

[0066] Further, the first circuit 310 and / or the second circuit 320 can be electrically connected to the second cavity wall 130 by any electrical connection method. In some embodiments, the first circuit 310 and / or the second circuit 320 are electrically connected to the second cavity wall 130 through a conductive member. The conductive member can be made of various conductive materials, such as metal members. The conductive member can also be of various shapes and structures, as long as the first circuit 310 and / or the second circuit 320 can be electrically connected to the second cavity wall 130 through the conductive member.

[0067] Please refer to Figure 3In some more specific embodiments, the first circuit 310 is wrapped with a conductive member 330 that is fixed in contact with the second cavity wall 130, and / or the second circuit 320 is wrapped with a conductive member 330 that is fixed in contact with the second cavity wall 130. The conductive member 330 is directly in contact with and fixed to the second cavity wall 130. When the first circuit 310 and / or the second circuit 320 are connected to the second cavity wall 130, the first circuit 310 and / or the second circuit 320 are also fixed and limited, and the first circuit 310 and / or the second circuit 320 are fixed on the second cavity wall 130, thereby positioning the ambient temperature detection unit 300. At the same time, the conductive member 330 is wrapped on the corresponding first circuit 310 or second circuit 320. This wrapping structure can prevent the first circuit 310 or the second circuit 320 from being separated from the conductive member 330, so as to ensure that the first circuit 310 or the second circuit 320 and the conductive member 330 maintain a stable electrical connection. Moreover, the metal wire needs to be exposed at the contact part between the first circuit 310 or the second circuit 320 and the conductive member 330. At this time, the conductive member 330 wraps the metal wire at this part to form protection to prevent other structures from damaging the metal wire and affecting the conduction effect of the metal wire.

[0068] More specifically, in some embodiments, the conductive member 330 is fixed to the second cavity wall 130 by welding. Of course, other methods of fixing may also be used, such as conductive bonding, clamping, etc.

[0069] The conductive member 330 is a flat ring structure, and the first circuit 310 is provided with the flat ring structure, and / or the second circuit 320 is provided with the flat ring structure. The flat ring structure presses and fixes the first circuit 310 or the second circuit 320. Figure 3 In some embodiments, the initial state of the flat ring structure can be a cylindrical structure. After the first line 310 or the second line 320 passes through the cylindrical structure, the cylindrical structure is flattened to obtain a flat ring structure that is pressed and fixed to the first line 310 or the second line 320.

[0070] In addition, in addition to achieving conductive connection and fixation through the conductive member 330, in some embodiments, the first circuit 310 and / or the second circuit 320 can also be directly welded to the second cavity wall 130, so that the first circuit 310 and / or the second circuit 320 are directly electrically connected to the second cavity wall 130, and at the same time, the first circuit 310 and / or the second circuit 320 are fixedly positioned on the second cavity wall 130.

[0071] Further, in some embodiments, please refer to Figure 1, the insertion end of the housing 100 is the front end of the entire probe (the lower end shown in the figure), and the end opposite to the front end is the rear end (the upper end shown in the figure). The housing 100 has a safety indicator line 103, which divides the housing 100 into an insertion area (also called a safety area) and an exposed area (also called a high temperature resistant area) in the axial direction of the housing 100. The area from the front end of the housing 100 to the safety indicator line 103 is the insertion area, and the first cavity 101 can be located in the insertion area so that components that are not resistant to high temperatures, such as the food temperature detection unit 400 and the control component 200, are located within the range of the insertion area. The insertion area is designed to be a part that is recommended and allowed to be fully inserted into the food when in use, and the temperature in the food is lower than that in the external cooking space, which can prevent the high temperature in the cooking space (for example, an oven above 200°C, a BBQ oven above 500°C, etc.) from damaging the electronic components of the temperature probe. The exposed area is the part that is recommended and allowed to be retained in the cooking space and located outside the food during the use of the temperature probe, that is, the structure in the exposed area is designed to be resistant to high temperatures and can withstand the high temperature environment in the cooking space. Of course, the safety indicator line 103 is only an indicator line that serves as a reminder. When used specifically, the part of the probe inserted into the food can also cross the safety indicator line 103, that is, part of the exposed area is also allowed to be inserted into the food. In addition, the safety indicator line 103 can also prevent the front end of the housing 100 from being damaged due to the temperature probe entering the object too deeply, and avoid burns to the operator. The area from the safety indicator line 103 to the rear end of the housing 100 is an exposed area, which is designed to be allowed to be exposed in the cooking space, that is, the structure in the exposed area is set to withstand the high temperature environment in the cooking space. At least a part of the second cavity 102 is arranged in the exposed area, so that the ambient temperature detection unit 300 therein can be in the exposed area, so as to better detect the ambient temperature of the cooking space.

[0072] In some embodiments, the electrical connection point between the first circuit 310 and / or the second circuit 320 and the second cavity wall 130 is located in the exposed area so that the temperature in the cooking space can be more accurately transferred from the second cavity wall 130 along the first circuit 310 and / or the second circuit 320 to the ambient temperature detection unit 300 to obtain a more accurate ambient temperature.

[0073] Furthermore, the probe can be inserted into food for use, and the inserted portion is usually required to cover or exceed the safety indicator line 103. Therefore, the portion of the exposed area close to the safety indicator line 103 may be inserted into the food. Or even if it is not inserted into the food, due to its proximity to the food, the temperature around this portion may be affected by the temperature of the food and deviate greatly from the maximum temperature of the cooking space. Therefore, in some embodiments, the electrical connection point between the first circuit 310 and / or the second circuit 320 and the second cavity wall 130 can be set as far away from the safety indicator line 103 as possible. Therefore, in some embodiments, in the axial direction of the shell 100, the end of the second cavity wall 130 close to the insulating member 120 is the first end, and the end away from the insulating member 120 is the second end, and the axial distance from the electrical connection point of the first circuit 310 and / or the second circuit 320 and the second cavity wall 130 to the first end is greater than the axial distance from the electrical connection point of the first circuit 310 and / or the second circuit 320 and the second cavity wall 130 to the second end, so as to ensure that the ambient temperature detection unit 300 can measure the ambient temperature of the cooking space more accurately.

[0074] Further, in some embodiments, please refer to Figure 3 and 4 as well as Fig.11 The control component 200 has a communication unit 224 (the communication unit 224 can have a separate communication chip or can be a main control chip 221) and an antenna 500. The antenna 500 is electrically connected to the communication unit 224 and extends into the second cavity 102. Please refer to Fig.12 In some more specific embodiments, the communication unit 224 may include a filter circuit 2241 and a communication chip 2242. The filter circuit 2241 may be composed of, but not limited to, a resistor and a capacitor, a filter chip, or other structures. The communication chip 2242 may be an RF chip, a Sub 1G chip, or other types of communication chips. Fig.12 In the illustrated embodiment, the communication chip 2242 is a chip separate from the main control chip 221 .

[0075] Of course, in other embodiments, please refer to Fig.11 and 12 , one of the first circuit 310 and the second circuit 320 can also connect the second cavity wall 130 with the charging circuit 223, and the other can be connected to the communication unit 224 to serve as the antenna of the communication unit 224. That is, in this embodiment, the first circuit 310 or the second circuit 320 can also have the antenna function to complete the wireless communication between the communication unit 224 and the external device. This structure can further simplify the internal structure of the probe, which is more conducive to the miniaturization design of the overall volume of the probe.

[0076] Furthermore, in some embodiments, the connection lines in the ambient temperature detection unit 300 and the antenna 500 (collectively referred to as the auxiliary function unit) pass through the insulating member 120 to be connected to the control component 200 located in the first cavity 101. Of course, in other embodiments, the connection lines in the ambient temperature detection unit 300 and the antenna 500 (collectively referred to as the auxiliary function unit) may also extend from the peripheral side of the insulating member 120 into the first cavity 101.

[0077] Please refer to Figure 6 and 7 In some embodiments, the antenna 500 is separately provided with the first circuit 310 or the second circuit 320 of the ambient temperature detection unit 300. The insulating member 120 is provided with a plurality of wiring holes 121 connecting the first cavity 101 and the second cavity 102. The first circuit 310, the second circuit 320 and the antenna 500 respectively pass through and are sealed and fixed in the corresponding wiring holes 121. The first circuit 310, the second circuit 320 and the antenna 500 are insulated and separated by the hole wall of the wiring hole 121. In this embodiment, the first circuit 310, the second circuit 320 and the antenna 500 are separately arranged in the corresponding wiring hole 121, and the material of the insulating member 120 itself can form insulation isolation for the first circuit 310 and the second circuit 320, so that the first circuit 310, the second circuit 320 and the antenna 500 located in the insulating member 120 can be exempted from the sleeve with an insulating function, and the metal wire can be directly passed through the wiring hole 121, which not only saves materials, but also reduces the wire diameter of the first circuit 310, the second circuit 320 and the antenna 500 located in the wiring hole 121, thereby reducing the aperture of the wiring hole 121, which is beneficial to reducing the radial size of the insulating member 120, and further beneficial to reducing the radial size of the entire probe. It can be understood that in some embodiments, the first circuit 310, the second circuit 320, the charging line and the antenna 500 can also be independently arranged, and each is sealed and fixed in the wiring hole 121.

[0078] Specifically, please refer to Figure 6 and 7 In some embodiments, there are three wiring holes 121, and the first circuit 310, the second circuit 320 and the antenna 500 are separately arranged in one wiring hole 121. Of course, when the auxiliary function unit also includes electronic components with other functions, the connection lines of these electronic components can also pass through the insulating member 120 to conduct with the control component 200. Correspondingly, more wiring holes 121 can also be set on the insulating member 120 for other connection lines to ensure that the wiring holes 121 correspond to each connection line one by one.

[0079] In addition, when in some embodiments, the function of the antenna 500 is integrated into the first circuit 310 or the second circuit 320, the insulating member 120 is provided with a plurality of routing holes 121 connecting the first cavity 101 and the second cavity 102. The first circuit 310 and the second circuit 320 respectively pass through the corresponding routing holes 121 and are sealed and fixed to the insulating member 120. The first circuit 310 and the second circuit 320 are insulated and separated by the hole walls of the routing holes 121.

[0080] For further information about the configuration of the communication unit 224, please refer to Figure 2 In some embodiments, the control circuit board 210 is provided with a main control chip 221 and at least one communication chip 2242, and the main control chip 221 and the communication chip 2242 are respectively arranged at different positions of the control circuit board 210. In this embodiment, the communication chip 2242 can use a chip specifically used to realize the communication function for communication control, for example, a communication chip such as an RF radio frequency chip or a Sub 1G chip can be used to improve the communication effect. Of course, in some other embodiments, the communication unit 224 can also be directly integrated on the main control chip 221.

[0081] Please continue to refer to Figure 2 In some embodiments, when the communication chip 2242 and the main control chip 221 are provided at the same time, they will occupy a larger area on the control circuit board 210. Therefore, in order to make the structure of the control circuit board 210 more compact, the main control chip 221 and the communication chip 2242 can be provided on the first surface and the second surface of the control circuit board 210. The first surface and the second surface are different surfaces on the control circuit board 210, which can be the front and back surfaces of the control circuit board 210, or two adjacent surfaces on the control circuit board 210. For example, Figure 2 In the illustrated embodiment, the main control chip 221 is disposed on a left side of the control circuit board 210 , and the communication chip 2242 is disposed on a right side of the control circuit board 210 .

[0082] Furthermore, in order to prevent liquid from flowing into the first cavity 101 from the wiring hole 121 of the insulating member 120, in some embodiments, a seal is formed between each connecting line and the wiring hole 121. Of course, the sealing method includes sealing between the hole wall of the wiring hole 121 and the corresponding connecting line, and the seal can adopt any structure that can achieve sealing and liquid-proof, such as but not limited to glue (liquid, liquid solidified into solid, solid solution), soft solid (silicone, TPU, etc.). In other embodiments, please refer to Figure 7 and 8, the sealing method may also include a sealing member 122 provided on one side of the insulating member 120 facing the second cavity 102, the sealing member 122 seals and separates the second cavity 102 from the wiring hole 121, the connection line passes through the sealing member 122 in a sealed manner, and is inserted into the first line 310 in the corresponding wiring hole 121. The sealing method between the sealing member 122 and the connection line and the sealing member 122 and the insulating member 120 may adopt any structure that can achieve sealing and liquid-proof, such as but not limited to glue (liquid, liquid solidified into solid, solid solution), soft solid (silicone, TPU, etc.), hard solid, etc. It can be understood that the sealing member 122 may also be provided on the side of the insulating member 120 facing the first cavity 101, so that it is located in the food as much as possible during use to avoid cracking, deformation, etc. caused by high temperature. In some embodiments, the sealing member 122 may also be filled or coated between the insulating member 120 and the first metal tube 110 or between the second metal tube 130.

[0083] Furthermore, since the probe is often inserted into liquid for use, there are certain requirements for the waterproof performance of the housing 100. Figure 7 and 8 In some embodiments, the first cavity wall 110 is a first metal tube 110, and the second cavity wall 130 is a second metal tube 130 (of course, in some other embodiments, the second cavity wall 130 may also include a portion other than the second metal tube 130). In order to improve the waterproof performance of the housing 100, the insulating member 120 has a first butt end 124, a second butt end 125, and a middle protrusion 123 located between the first butt end 124 and the second butt end 125. The peripheral side surface of the first butt end 124 and the middle protrusion 123 form a first butt surface 1261. The first metal tube 110 is sealed and sleeved on the first butt surface 1261. The peripheral side surface of the second butt end 125 and the middle protrusion 123 form a second butt surface 1262. The second metal tube 130 is sealed and sleeved on the second butt surface 1262. The first butt joint surface 1261 and the second butt joint surface 1262 can increase the sealing area between the first butt joint end 124 and the first metal tube 110 and between the second butt joint end 125 and the second metal tube 130, which not only increases the sealing area but also enables two or more sealing methods to be set simultaneously in the larger sealing area.

[0084] Please refer to Figure 7 In some embodiments, a sealing structure is provided between the first butt joint surface 1261 and the inner wall of the first metal tube 110; and a sealing structure is provided between the second butt joint surface 1262 and the inner wall of the second metal tube 130. The sealing structure includes at least two sealing modes to increase the sealing effect.

[0085] More specifically, please refer to 7. In some embodiments, the sealing structure includes fixing the first metal tube 110 to the first docking surface 1261 and sealing and fixing the second docking end 125 to the second docking surface 1262 by means of glue. The sealing structure also includes providing a sealing ring 1263 or other sealing members between the first metal tube 110 and the first docking surface 1261 and between the second docking end 125 and the second docking surface 1262.

[0086] More specifically, please refer to Figure 7 and 8 In some embodiments, the cross-section of the first butt joint surface 1261 and the second butt joint surface 1262 is sloped to increase the sealing area. In other embodiments, the cross-section of the first butt joint surface 1261 and the second butt joint surface 1262 may also be, but not limited to, stepped, wavy, or broken line-shaped.

[0087] Furthermore, in some embodiments, the safety indication line 103 may be a line or a concave-convex three-dimensional engraved line with a surface color obviously different from other areas of the housing 100, for indicating to the user the depth of the probe inserted into the object to be measured (eg, food).

[0088] More specifically, please refer to Figure 1 and 8 In some embodiments, the peripheral side surface of the middle raised portion 123 of the insulating member 120 forms the safety indication line 103. By using the structure of the insulating member 120 to form the safety indication line 103, there is no need to perform additional surface treatment to mark the safety indication line 103, which can simplify the processing process and reduce the manufacturing cost.

[0089] Further, in order to enclose and form the first cavity 101, please refer to Figure 5 In some embodiments, the first metal tube 110 and the first butt end 124 of the insulating member 120 are sealed and butt-jointed to form a first cavity 101. Of course, in other embodiments, the first cavity 101 in the housing 100 can be implemented by other existing structures.

[0090] Furthermore, the control assembly 200 includes a control circuit board 210, which can be fixedly installed in the first cavity 101 by screws or other methods, and this fixing method is hard fixing. This hard fixing method is prone to assembly deviation, which can easily lead to assembly interference failure, pad cracking failure and other problems.

[0091] In this regard, please refer to some embodiments of this application. Figure 3 and 4The first circuit 310, the second circuit 320 and the antenna 500 (the function of the antenna 500 may also be concurrently on the first circuit 310 or the second circuit 320) pass through the insulating member 120 and are fixedly connected to the insulating member 120. The control circuit board 210 is movably arranged in the first cavity 101, and one end of the first circuit 310, the second circuit 320 and the antenna 500 extending into the first cavity 101 is fixedly connected to the control circuit board 210 to limit the position of the control circuit board 210 in the axial direction of the housing 100. For example, the fixing effect can be increased by welding and glue fixing. The first circuit 310, the second circuit 320 and the antenna 500 are fixed to the insulating member 120 or the second cavity wall 130, so their positions in the axial direction of the shell 100 are fixed, and the position of the control circuit board 210 along the axial direction of the shell 100 can be controlled within a certain range. In addition, the first circuit 310, the second circuit 320 and the antenna 500 have a certain degree of deformability, so the control circuit board 210 has a certain adjustment space along the axial direction of the shell 100, which can allow a certain degree of assembly error, thereby reducing the possibility of failure.

[0092] In order to prevent the control circuit board 210 from rotating or moving too much in the axial direction in the first cavity 101, please refer to Fig. 9 In some embodiments, the size of the cavity wall of the first metal tube 110 is adapted to the size of the control circuit board 210 so as to prevent the control circuit board 210 from rotating in the first metal tube 110. The adaptation means that the size of the area in the first metal tube 110 where the control circuit board 210 is arranged and the size of the control circuit board 210 only have a normal assembly gap, and the assembly gap is extremely small, so that the control circuit board 210 cannot rotate in the first metal tube 110. Moreover, although there is an assembly gap between the first metal tube 110 and the control circuit board 210, due to the extremely small assembly gap, the control circuit board 210 is only allowed to be inserted into the first metal tube 110 according to a specific assembly direction. Therefore, even if the control circuit board 210 has some movement along the axial direction of the housing 100, it is almost impossible to move completely in the assembly direction because these movements are in random directions. Therefore, the first metal tube 110 can also form a certain limit effect on the control circuit board 210 in the axial direction to prevent the control circuit board 210 from moving too much in the axial direction and causing it to be separated from the connection line.

[0093] In some embodiments, the first cavity 101 may also be filled with a heat-conducting waterproof material so that the waterproof material covers or wraps the control circuit board 210. This not only protects the control circuit board 210 and prevents the control circuit board 210 from getting damp, but also speeds up the heat conduction rate from the external temperature outside the shell 100 to the control circuit board 210, thereby facilitating the temperature sensor disposed on the control circuit board 210 to detect the external temperature.

[0094] On the other hand, please refer to Figure 5 and 8 In some embodiments, the housing 100 includes a rear insulation kit 140, and the second metal tube 130, the rear insulation kit 140 and the insulation member 120 may enclose a second cavity 102. Of course, in other embodiments, the second cavity 102 may also be enclosed by an existing structure or other structures.

[0095] Please refer to Figure 5 and 8 In some embodiments, the end of the second metal tube 130 facing away from the insulating member 120 is the second end, and the tail insulation sleeve 140 is sleeved on the peripheral side surface of the second end of the second metal tube 130 .

[0096] Please refer to Figure 5 and 10 In some embodiments, in order to improve the sealing effect and prevent rotation, the tail insulation kit 140 has a plurality of multi-level step structures 141, and the plurality of step structures at least include a first step 1411, a second step 1412, and a third step 1413 arranged along the axial direction of the housing 100. The first step 1411 forms a sealing gap with the peripheral side surface of the second end of the second metal tube 130, and a sealing structure is arranged in the sealing gap. The sealing structure may be made of, but not limited to, glue (liquid, liquid solidified into solid, solid solution), soft solid (silicone, TPU, etc.). The second step 1412 is tightly matched with the peripheral side surface of the second end of the second metal tube 130 to increase the limiting and sealing effects by a tight fit, and at the same time, the coaxiality of the second metal tube 130 and the tail insulation kit 140 can be ensured.

[0097] Please refer to Figure 5 , 8 In some embodiments, in order to prevent rotation, the second end of the second metal tube 130 has a plurality of notches 131 arranged along the circumference of the second metal tube 130, and the third step 1413 is inserted into the corresponding notches 131 to prevent the second metal tube 130 and the tail insulation kit 140 from rotating relative to each other.

[0098] Of course, in other embodiments, the first step 1411, the second step 1412, and the third step 1413 may also be selected as part thereof according to different requirements. For example, in some embodiments, the plurality of step structures include the first step 1411 and the third step 1413, or include the second step 1412 and the third step 1413, or include the first step 1411 and the second step 1412.

[0099] Further, in some embodiments, please refer to Figure 3, further comprising a rechargeable battery 600, which is disposed in the first cavity 101 and is electrically connected to the control assembly 200. In the axial direction of the housing 100, the rechargeable battery 600 is disposed between at least one food temperature detection unit 400 (for example, the food temperature detection unit 400 at the front end) and the control assembly 200. The at least one food temperature detection unit 400 is electrically connected to the control assembly 200 via a connecting line 610, and the connecting line 610 is fixed to the rechargeable battery 600. In this embodiment, the food temperature detection unit 400 is fixed by using the rechargeable battery 600, and there is no need to set up a fixing seat for the food temperature detection unit 400 separately, which can simplify the internal structure, not only reducing the cost, but also facilitating the miniaturization design of the probe.

[0100] Further, in some embodiments, please refer to Figure 3 The connection line 610 is fixed to the rechargeable battery 600 by means of a high temperature tape 700. In this embodiment, the high temperature tape 700 can be made very thin, for example, only 0.04 mm, which can greatly compress the space. Moreover, the high temperature tape 700 is a consumable material with low cost, and no additional structural parts that need to be molded are required, thereby reducing the material cost and mold cost.

[0101] On the other hand, the present application also provides a temperature probe assembly, please refer to Figure 13-18 In some embodiments, the temperature probe assembly includes a temperature probe 1 and a temperature probe receiving base 2. The temperature probe 1 can be received in a probe receiving cavity 211 of the temperature probe receiving base 2 and can be taken out of the probe receiving cavity 211. The temperature probe 1 can be inserted into the food during or after cooking to detect the temperature inside the food.

[0102] Specifically, the temperature probe 1 can be inserted into the food during the cooking process to detect the temperature inside the food, especially to obtain the lowest temperature inside the food as accurately as possible. The food can be in any cooking space, including but not limited to: steaming, boiling, baking, roasting, frying, deep-frying, etc. or heat-treated by any other means.

[0103] In order to form a temperature probe storage base 2 (referred to as the base) that is easier to hold and more portable, please refer to Figure 13-18 In some embodiments, the base 2 includes a base body 21 and a display module 22. The display module 22 has a screen 221. The display module 22 can be a pure display screen module or a touch display screen module capable of touch operation. Correspondingly, the screen 221 can be a pure display screen or a touch display screen. The display module 22 is installed on the base body 21, and the screen 221 is located on one side of the base body 21.

[0104] Please refer to Figure 13-18In some embodiments, the seat 21 has at least one probe accommodating cavity 211 for accommodating the temperature probe 1. The probe accommodating cavity 211 has a cavity shape that matches the shape of the corresponding temperature probe 1 to accommodate the temperature probe 1. Since the temperature probe 1 is usually a long strip structure, the corresponding probe accommodating cavity 211 corresponds to a cavity structure extending in the longitudinal direction. Figure 13-18 In the illustrated embodiment, the temperature probe 1 can be completely received in the probe receiving cavity 211. In other embodiments, the temperature probe 1 can also be received in the probe receiving cavity 211 in a semi-embedded manner or in other manners.

[0105] Please refer to Fig.13 and 14 In some embodiments, in the direction perpendicular to the screen 2021 (referred to as the first direction a), the probe accommodating cavity 2011 is arranged on the side opposite to the display surface of the screen 2021 (i.e., the back of the display module 202). In this embodiment, the space on the back of the display module 22 is used to set the probe accommodating cavity 211, thereby reducing the size of the base 2 in the direction parallel to the screen 221 (referred to as the second direction b), forming a structure that is easier to hold, and improving the portability of the base 2. In contrast, if the probe accommodating cavity 211 and the screen 221 are arranged along the second direction b, since the width of the screen 221 is greater than its thickness, this arrangement will increase the size of the base 21 in the second direction b, making it inconvenient to carry and hold.

[0106] Or, in other embodiments, please refer to Fig.13 and 14 , the screen 221 may not be used as a reference, and the probe accommodating cavity 211 and the screen 221 may be arranged along the thickness direction of the base 21. The base 21 generally has three dimensions: length, width, and thickness, and the thickness direction is the direction in which the base 21 has the smallest dimension. Fig.13 and 14 In the illustrated embodiment, the thickness direction of the base 21 is the first direction a shown in the figure, the width direction is the second direction b shown in the figure, and the length direction is the third direction c shown in the figure. Of course, in other embodiments, the thickness direction and the width direction of the base 21 may also be other directions. In this embodiment, the space in the thickness direction may be used to set the probe accommodating cavity 211, thereby reducing the size of the base 2 in the direction parallel to the screen 221, forming a structure that is easier to hold, and at the same time improving the portability of the base 2.

[0107] For further information, please refer to Figure 13-18In some embodiments, the probe accommodating cavity 211 has a side groove 212, and the side groove 212 can be used for the user to observe the internal situation of the probe accommodating cavity 211, such as observing whether there is a temperature probe 1, the placement status of the temperature probe 1 in the probe accommodating cavity 211, the charging status of the temperature probe 1 (such as the seat 21 has a charging function) or other situations.

[0108] To prevent the temperature probe 1 from falling out of the side slot 212 , in some embodiments, the length and / or width of the side slot 212 may be designed to be smaller than the temperature probe 1 , so that the temperature probe 1 cannot fall out of the side slot 212 .

[0109] Please refer to Figure 13-18 In some embodiments, the base 21 has a first surface and a second surface facing away from each other, the screen 221 is provided on the first surface, and the side slot 212 is provided on the second surface. In this structure, the screen 221 and the side slot 212 are provided facing away from each other, making full use of the space on the two surfaces facing away from each other on the base 21, thereby increasing the compactness of the base 21 structure and improving the portability and grip of the base 2.

[0110] Please refer to Figure 13-18 In some embodiments, the side groove 212 is arranged along the longitudinal direction of the probe accommodating cavity 211 , which can expand the user's observation field of view, so that the user can better observe the temperature probe 1 in the probe accommodating cavity 211 from the side groove 212 .

[0111] Please refer to Figure 13-18 In some embodiments, one end of the probe accommodating cavity 211 has a probe insertion port 213, which is disposed at one end of the probe accommodating cavity 211 in the longitudinal direction, and the temperature probe 1 can be inserted into the probe accommodating cavity 211 through the probe insertion port 213. One end of the side slot 212 is directly connected to the probe insertion port 213, which can not only expand the user's observation field of view, but also increase the opening size of the probe insertion port 213, so as to more conveniently insert the temperature probe 1 into the probe accommodating cavity 211.

[0112] In addition, in some other embodiments, the probe insertion port 213 of the probe accommodating cavity 211 may also be arranged along the longitudinal direction of the probe accommodating cavity 211, so that the temperature probe 1 can be inserted into the probe accommodating cavity 211 from the side of the probe accommodating cavity 211. Figure 13-18 In the illustrated embodiment, the side slot 212 may also be designed to have a size and shape that allows the temperature probe 1 to be inserted into the probe accommodating cavity 211 . In this embodiment, the original probe insertion port 213 located at one longitudinal end of the probe accommodating cavity 211 may be omitted.

[0113] In other embodiments, the probe accommodating cavity 211 is a hole-shaped structure, one end of the hole-shaped structure is provided with a probe insertion port 213, and the periphery of the hole-shaped structure is closed. In this case, the probe accommodating cavity 211 of the hole-shaped structure can surround the temperature probe 1 in the circumferential direction of the temperature probe 1, and can prevent other objects from entering the probe accommodating cavity 211, which can not only protect the temperature probe 1, but also protect the structure of the probe accommodating cavity 211 from being damaged.

[0114] Furthermore, the number of the probe accommodating cavity 211 may be one or more. Fig.13 and 14 In the illustrated embodiment, the number of the probe accommodating cavity 211 is one, into which one temperature probe 1 can be inserted. Figure 15-18 In the illustrated embodiment, there are at least two probe accommodating cavities 211, which are arranged side by side in a direction parallel to the screen 221. The arrangement direction of the probe accommodating cavities 211 is substantially parallel to the screen 221, so that the back space of the screen 221 can be fully utilized.

[0115] Specifically, in Fig.15 and 16 In the illustrated embodiment, the number of the probe accommodating chambers 211 is two, and two temperature probes 1 can be inserted into the two probe accommodating chambers 211. Fig.17 and 18 In the illustrated embodiment, there are four probe accommodating cavities 211 , which can accommodate four temperature probes 1 .

[0116] Furthermore, the base 2 may be a simple storage device, that is, it is mainly used to store the temperature probe 1, and it may not have the function of charging the temperature probe 1. Of course, in other embodiments, the base 2 may also include a charging module (not shown in the figure), which is installed on the base 21 to charge the temperature probe 1 inserted into the probe accommodating cavity 211. The charging module can be either a wireless charging method or a wired charging method. For example, the charging module may have a charging contact arranged on the inner wall of the probe accommodating cavity 211. When the temperature probe 1 is inserted into the probe accommodating cavity 211, the charging contact can be conductively connected to the temperature probe 1 to achieve charging.

[0117] Specifically, please refer to Fig.19In some embodiments, the probe accommodating cavity 2011 is provided with a first charging contact 2031 and at least one second charging contact 2032. When the first charging contact 2031 and any second charging contact 2032 are connected, the base 201 is used to charge the temperature probe 1 inserted into the probe accommodating cavity 2011. It can be understood that the second charging contact 2032 can be distributed at different positions along the longitudinal direction of the probe accommodating cavity 2011. When the temperature probe 1 contacts the first charging contact 2031 and any second charging contact 2032, charging can be performed, thereby avoiding the situation that the temperature probe 1 is not fully inserted to the bottom and cannot be charged.

[0118] Please refer to Fig.19 In some embodiments, the number of the second charging contacts 2032 is 2, one is located at the bottom of the probe accommodating cavity 2011, and the other is located at the longitudinal length of the probe accommodating cavity 2011 which is 1 / 3 of the bottom of the probe accommodating cavity 2011.
