Description

Technical Field

[0001] The utility model belongs to the technical field of temperature measurement, and specifically relates to a temperature measurement probe. Background Art

[0002] In the cooking and food processing industries, precise temperature control of food is a basic requirement to ensure food quality, taste and safety. Temperature probes, as an important tool to achieve this goal, are widely used in various cooking scenarios such as barbecue, baking, and steaming. With its unique design, the temperature probe can be directly inserted into the food to monitor and feedback the temperature information of the food in real time, helping users to accurately judge the cooking status of the food and ensure that the food reaches the predetermined degree of cooking.

[0003] With the rapid development of wireless communication technology, temperature probes have gradually integrated wireless connection functions, allowing users to view food temperature data in real time through smart terminal devices away from the cooking site. This innovation not only improves the user experience, but also increases the convenience and flexibility of cooking. However, in the process of integrating wireless communication modules, such as antennas, into temperature probes, multiple complex challenges are faced.

[0004] First of all, the long needle-like structure of the temperature measuring probe determines the narrowness and limitation of its internal space. Arranging wireless communication components such as onboard antennas or spring antennas in such a small space undoubtedly increases the difficulty of design. The addition of antennas not only increases the number of parts of the probe, but also makes the overall structure more complex and compact. This compact layout may not only limit the performance of the antenna and affect the stability of the signal, but also increase the failure rate of the probe and reduce its service life.

[0005] Secondly, the temperature probe integrates multiple components with different functions, such as temperature sensors, circuit boards, power supplies, etc. These components may generate electromagnetic interference during operation, which may have an adverse effect on the signal transmission and reception of the antenna. In order to ensure accurate data transmission, a series of complex shielding measures need to be taken during the design and manufacturing process to reduce or eliminate these interferences. This not only increases the difficulty of design and manufacturing, but may also affect the overall performance and reliability of the probe.

[0006] In addition, the complex assembly process is also a major challenge in the manufacturing process of temperature probes. Accurately assembling multiple parts in a small internal space requires highly professional skills and experience. This not only requires a lot of manpower and time, but also may increase the defective rate of products due to assembly errors, further pushing up production costs. Utility Model Content

[0007] The primary purpose of the present invention is to solve at least one of the above problems and provide a temperature measuring probe.

[0008] In order to meet the various purposes of the utility model, the utility model adopts the following technical solutions:

[0009] A temperature measuring probe is provided to meet one of the purposes of the utility model, including a shell and a control circuit and an antenna structure arranged in the shell, the antenna structure including a signal transmitting structure and a signal line, the signal transmitting structure is arranged on one end of the shell, and the signal transmitting structure is electrically connected to the control circuit via the signal line, and the shell is provided with an opening exposing the signal transmitting structure.

[0010] Furthermore, a battery and positive and negative charging electrodes are provided in the housing, a charging circuit is provided in the control circuit, the charging circuit is electrically connected to the battery, the positive and negative charging electrodes include a first electrode and a second electrode, the signal transmitting structure is the first electrode, and the signal transmitting structure is electrically connected to the charging circuit via the signal line.

[0011] Furthermore, the temperature measuring probe includes charging positive and negative electrodes, the charging positive and negative electrodes include a second electrode, and the signal transmitting structure is sleeved outside the second electrode.

[0012] Specifically, the second pole and the signal transmitting structure are arranged at the same end, the second pole is columnar, the signal transmitting structure is an annular structure, the signal transmitting structure is sleeved on the second pole, and the second pole is electrically connected to the charging circuit via a charging line.

[0013] Specifically, a containing space is provided in the signal transmitting structure, the second pole is provided in the containing space, and the second pole is spaced apart from a side wall surrounding the containing space.

[0014] In one embodiment, an insulating sleeve is further provided in the accommodating space, an insulating hole is provided in the insulating sleeve, and the second pole is inserted into the insulating hole.

[0015] Specifically, the signal line and the charging line are insulated from each other, and an insulating sheet is also provided between the signal line and the charging line.

[0016] Specifically, the signal line and the charging line are both sheet metal wires.

[0017] In one embodiment, a narrow and long space is formed in the shell, and the battery and the positive and negative charging electrodes are respectively arranged at two ends of the narrow and long space.

[0018] In one embodiment, the first electrode is a negative electrode, and the second electrode is a positive electrode.

[0019] Compared with the prior art, the present invention has many advantages, including but not limited to:

[0020] First of all, the temperature measuring probe of the present invention greatly simplifies the internal structure of the temperature measuring probe by setting the signal transmitting structure at one end of the shell and connecting it to the internal control circuit through a signal line. In traditional temperature measuring probes, the antenna structure may need to occupy a large space inside the probe, while the present invention places the main part of the antenna structure - the signal transmitting structure at one end of the shell, freeing up the internal space so that other key components such as temperature sensors, circuit boards, batteries, etc. can be more reasonably laid out. Due to the optimization of the internal space, the temperature measuring probe of the present invention is more convenient during the assembly process. Assemblers can more easily place each component accurately in the corresponding position without worrying about insufficient space or chaotic layout. This not only improves assembly efficiency, but also reduces the possibility of assembly errors.

[0021] Secondly, placing the signal transmitting structure at one end of the shell reduces its close contact with other internal electronic components, thereby reducing the risk of electromagnetic interference and helping to ensure the purity and stability of the signal. Moreover, the signal transmitting structure can communicate directly with the external environment without the need for conduction and attenuation through the internal structure, making the signal transmission efficiency higher, capable of transmitting temperature data more quickly, and reducing data transmission delays. The signal coverage range of traditional temperature measuring probes may be limited because the antenna structure is built into the probe. The utility model, by placing the signal transmitting structure at one end of the shell, can transmit signals more effectively, thereby expanding the signal coverage range. This allows users to receive temperature data at a farther distance, improving the practicality of the temperature measuring probe.

[0022] In addition, exposing the signal transmission structure directly to the air helps reduce the interference of internal components on the signal. At the same time, the opening of the shell can also prevent other objects from blocking or interfering with the signal transmission structure, further improving the stability of the signal, making the transmission of temperature data more reliable, and reducing errors or interruptions caused by signal problems.

[0040] Those skilled in the art will understand that, unless otherwise defined, all terms (including technical terms and scientific terms) used herein have the same meaning as the general understanding of ordinary technicians in the field to which the utility model belongs. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as the meaning in the context of the prior art, and will not be interpreted with idealized or overly formal meanings unless specifically defined as here.

[0041] The utility model provides a temperature measuring probe, in which an antenna structure is provided. The antenna structure is arranged at one end of a shell, and the antenna structure is composed of a positive pole or a negative pole of the temperature measuring probe, which can optimize the structure of the temperature measuring probe and improve signal transmission efficiency.

[0042] In an exemplary embodiment of the present invention, Figure 1 , Figure 2 and Figure 3 The temperature measuring probe 100 includes a housing 110, a single-ended charging component, a control circuit 130, a communication unit (the communication unit is referred to as a first communication unit 140) and a temperature sensor 150. The single-ended charging component, the control circuit 130 and the temperature sensor 150 are arranged in the housing 110, and the control circuit 130 is electrically connected to the single-ended charging component, the temperature sensor 150 and the first communication unit 140 respectively.

[0043] The control circuit 130 is provided with a control unit (the control unit is referred to as a first control unit 131). The first control unit 131 controls the temperature sensor 150 to detect the external temperature. The temperature sensor 150 outputs the acquired temperature information to the first control unit 131. The first control unit 131 transmits the temperature information to the outside via the first communication unit 140 so that the user can obtain the temperature information in time.

[0044] In an exemplary embodiment of the present invention, Figure 2 The first communication unit 140 includes an antenna structure, the antenna structure includes a signal transmission structure 143 and a signal line 144, and the signal transmission structure 143 is electrically connected to the first control unit 131 through the signal line 144. The first control unit 131 sends a signal to the signal transmission structure 143 through the signal line 144, and the signal transmission structure 143 is excited to transmit the signal to the outside, so that the external device can receive the signal.

[0045] The housing 110 is provided with the first opening 1132 corresponding to the signal transmitting structure 143, so that the signal transmitting structure 143 can directly transmit signals to the outside without being shielded by other components of the temperature measuring probe 100, thereby improving the signal transmission efficiency of the antenna structure.

[0046] In this embodiment, the control circuit 130 further includes a feeding circuit, and the feeding circuit is electrically connected to the signal transmitting structure 143 via the signal line 144. The first control unit 131 sequentially transmits an excitation current to the signal transmitting structure 143 via the feeding circuit and the signal line 144, so that the signal transmitting structure 143 resonates and transmits a radio frequency signal to the outside.

[0047] In this embodiment, combined with Figure 4 and Figure 6 , the signal transmitting structure 143 is also the negative electrode 123 of the single-ended charging component, and the signal line 144 is the first charging line 125 led out of the negative electrode 123. In other words, the antenna structure is composed of the negative electrode 123 and the first charging line 125, so that the temperature measuring probe 100 of the present invention does not need to be equipped with a separate antenna. The traditional temperature measuring probe transmits signals to the outside by setting an onboard antenna or a spring antenna, but the present invention does not need to increase the number of parts of the temperature measuring probe 100, and directly uses the existing negative electrode 123 and the first charging line 125 to form an antenna structure to transmit signals to the outside, thereby reducing the number of parts of the temperature measuring probe 100, reducing the difficulty of assembly, and reducing production costs.

[0048] In one embodiment, in the antenna structure, the positive electrode 124 can also be used as the signal transmitting structure 143 , and the second charging line 126 led out from the positive electrode 124 can be used as the signal line 144 .

[0049] Combination Figure 3 , Figure 4 and Figure 5 The housing 110 has a narrow and long space 111 formed therein for installing the components of the temperature measuring probe 100. Specifically, the housing 110 includes a needle body 112 and a handle 113. The needle body 112 has a blind hole 1121, and the handle 113 has an installation space 1131. The needle body 112 is inserted into the installation space 1131, so that the blind hole 1121 and the installation space 1131 are connected to each other to define the narrow and long space 111 together.

[0050] The single-end charging component includes a battery (the battery is referred to as a first battery 121) and charging positive and negative electrodes (the charging positive and negative electrodes are referred to as first charging positive and negative electrodes 122), and the first charging positive and negative electrodes 122 are electrically connected to the first battery 121 to charge the first battery 121 through the first charging positive and negative electrodes 122. The first battery 121 is electrically connected to the control circuit 130 to power the temperature measuring probe 100.

[0051] The first charging positive and negative electrodes 122 include a first electrode 123 and a second electrode 124. In this embodiment, one of the first electrode 123 and the second electrode 124 is a positive electrode and the other is a negative electrode. In this embodiment, the first electrode 123 is a negative electrode and the second electrode 124 is a positive electrode to describe the present invention, but this should not be construed as limiting the present invention. It is understandable that when the first electrode 123 is a negative electrode, the first electrode 123 can be used as the signal emission structure 143.

[0052] Combination Figure 5 The first charging positive and negative electrodes 122 are arranged in the installation space 1131 of the handle 113, and the installation space 1131 is provided with an opening corresponding to the first charging positive and negative electrodes 122 (the opening is referred to as the first opening 1132) to expose the first charging positive and negative electrodes 122, so that an external charging device can charge the first battery 121 through the first charging positive and negative electrodes 122.

[0053] Combination Figure 4 and Figure 6, the first pole 123 is an annular structure, the second pole 124 is a columnar structure, the first pole 123 is sleeved with the second pole 124, that is, the second pole 124 is inserted into the first pole 123. Specifically, a receiving space 1231 is provided in the first pole 123, the second pole 124 is inserted into the receiving space 1231, and the second pole 124 is spaced apart from the side wall surrounding the receiving space 1231, so that the first pole 123 and the second pole 124 are insulated from each other to avoid direct electrical connection between the first pole 123 and the second pole 124, thereby preventing a short circuit, or damaging the temperature measuring probe 100, or even causing a safety accident. In a further embodiment, the annular structure of the first pole 123 can extend along the central axis of the housing 110 to form a sleeve structure, and the second pole 124 extends along the length corresponding to the first pole 123.

[0054] In this embodiment, the first pole 123 includes a charging end (the charging end is referred to as the first charging end 1232), and the second pole 124 also includes a charging end (the charging end is referred to as the second charging end 1241). The first charging end 1232 and the second charging end 1241 are exposed to the outside through the first opening 1132, so that the first charging end 1232 and the second charging end 1241 can be electrically connected to an external charging device through the first opening 1132, and the external charging device charges the first battery 121 through the first charging end 1232 and the second charging end 1241.

[0055] Specifically, the first charging end 1232 corresponds to the structure of the first pole 123 , and the first charging end 1232 is a ring-shaped structure; the second charging end 1241 corresponds to the structure of the second pole 124 , and the second charging end 1241 is a sheet-shaped structure.

[0056] In this embodiment, an insulating sleeve 161 is further provided in the accommodating space 1231. An insulating hole 1611 is provided in the insulating sleeve 161. The insulating hole 1611 is a through hole. The second pole 124 is inserted into the insulating hole 1611. The first pole 123 and the second pole 124 are separated by the insulating sleeve 161, that is, the first pole 123 and the second pole 124 are insulated from each other. In this embodiment, it is recommended that the insulating sleeve 161 is made of plastic or ceramic material.

[0057] Combination Figure 1 The control circuit 130 includes a charging circuit (the charging circuit is referred to as a first charging circuit 132), and the first charging circuit 132 is electrically connected to the first battery 121 and the first charging positive and negative electrodes 122 respectively, so that the first charging positive and negative electrodes 122 charge the first battery 121 through the first charging circuit 132.

[0058] Specifically, combined Figure 4 and Figure 6 , the first pole 123 and the second pole 124 each lead out a charging line to electrically connect the first charging circuit 132. The charging line led out of the first pole 123 is called the first charging line 125, and the charging line led out of the second pole 124 is called the second charging line 126. The first charging line 125 and the second charging line 126 are electrically connected to the first charging circuit 132 respectively, and the first charging line 125 and the second charging line 126 are insulated from each other to avoid the first charging line 125 and the second charging line 126 being connected to each other and short-circuited. In one embodiment, the first charging line 125 and the second charging line 126 are both sheet metal wires to reduce production difficulty and reduce production costs.

[0059] In this embodiment, the first charging line 125 and the second charging line 126 are arranged relatively spaced apart, so that a spacing space is formed between the first charging line 125 and the second charging line 126 to separate the first charging line 125 and the second charging line 126, so that the first charging line 125 and the second charging line 126 are insulated from each other.

[0060] Preferably, the first charging cable 125 and the second charging cable 126 are respectively arranged on the two side surfaces of the narrow and long space 111, and an insulating layer is provided on the surface of the first charging cable 125 and the second charging cable 126 respectively connected to the side of the narrow and long space 111 to prevent the first charging cable 125 and / or the second charging cable 126 from being electrically connected to the housing 110.

[0061] In one embodiment, an insulating sheet 162 is disposed in the space between the first charging line 125 and the second charging line 126, and the insulating sheet 162 further separates the first charging line 125 and the second charging line 126 to prevent the first charging line 125 and the second charging line 126 from short-circuiting after contact. In this embodiment, it is recommended that the insulating sheet 162 is made of ceramic material.

[0062] In a typical embodiment of the present invention, the control circuit 130 is integrated on a first circuit board 133 , and the first charging line 125 and the second charging line 126 are electrically connected to a first charging circuit 132 integrated on the first circuit board 133 , respectively.

[0063] In one embodiment, in combination Figure 4 and Figure 5, a pair of elastic clips 165 are further provided in the housing 110, and the pair of elastic clips 165 are provided on both sides of the first circuit board 133, and the elastic clips 165 elastically abut against the adjacent side walls of the housing 110, and the pair of elastic clips 165 elastically abut against the two side walls of the housing 110, respectively, so that the first circuit board 133 is stably provided in the housing 110. In this embodiment, a plurality of pairs of elastic clips 165 are provided in the housing 110, and the plurality of pairs of elastic clips 165 are sequentially provided on the first circuit board 133 along the central axis of the housing 110, so that the first circuit board 133 can be further stably provided in the housing 110 under the elastic limitation of the plurality of pairs of elastic clips 165.

[0064] In one embodiment, in combination Figure 4 In order to facilitate fixing the first battery 121, the first battery 121 is fixed by the first circuit board 133. Specifically, one of the first circuit board 133 and the first battery 121 has a plug-in slot 1211, and the other has a plug-in portion 1331, and the plug-in portion 1331 is plugged into the plug-in slot 1211, so that the first circuit board 133 and the first battery 121 are fixed to each other. In this embodiment, it is recommended that the first battery 121 is provided with a plug-in slot 1211, and the first circuit board 133 is provided with a plug-in portion 1331. Preferably, the plug-in portion 1331 is one of the ends of the first circuit board 133.

[0065] Specifically, the handle 113 is provided with the first opening 1132 corresponding to the first charging positive and negative electrodes 122, so that the first electrode 123 can directly transmit signals to the outside without being shielded by other components of the temperature measuring probe 100, thereby improving the signal transmission efficiency of the antenna structure.

[0066] Because the first pole 123 and the second pole 124 are insulated from each other, the second pole 124 will not interfere with the first pole 123 used as the signal emitting structure 143 transmitting signals to the outside. Specifically, the first pole 123 is provided with the insulating sleeve 161, and the first pole 123 is inserted into the insulating sleeve 161, so that the first pole 123 and the second pole 124 are shielded from each other by the insulating sleeve 161, thereby preventing the second pole 124 from interfering with the signal emitting structure 143.

[0067] The handle 113 is made of insulating material. In this embodiment, it is recommended that the handle 113 is made of ceramic material or plastic material. Since the handle 113 is made of insulating material, the handle 113 will not interfere with the signal transmitting structure 143 disposed in the installation space 1131 thereof to transmit signals to the outside. Moreover, the handle 113 will not be electrically connected to the first pole 123, so that when the first pole 123 is charging the first battery 121, it will not be interfered by the handle 113, which will cause a decrease in charging efficiency or charging failure.

[0068] Because the first charging line 125 and the second charging line 126 are insulated from each other, the second charging line 126 will not interfere with the first charging line 125 sending a signal to the first pole 123. Specifically, the insulating sheet 162 is provided between the first charging line 125 and the second charging line 126, and the first charging line 125 and the second charging line 126 are shielded from each other by the insulating sheet 162, so as to prevent the second charging line 126 from interfering with the signal of the first charging line 125.

[0069] In an exemplary embodiment of the present invention, Figure 3 The housing 110 is composed of the needle body 112 and the handle 113 , and the needle body 112 is inserted into the installation space 1131 of the handle 113 to form the housing 110 .

[0070] Specifically, combined Figure 7 The needle body 112 includes a plug section 1122, one end of the needle body 112 is a plug end 1123, and the plug end 1123 is also the end of the plug section 1122, and the opening of the blind hole 1121 (the opening is called the second opening 1124) is arranged at the plug end 1123. Figure 8 and Fig. 9 The plug-in section 1122 is inserted into the installation space 1131 of the handle 113, so that the second opening 1124 of the blind hole 1121 is connected to the installation space 1131 of the handle 113 to form the narrow and long space 111, and the components of the temperature measuring probe 100 are accommodated through the narrow and long space 111.

[0071] Combination Fig.10 The plug section 1122 is tightly fitted with the inner wall of the installation space 1131, so that the plug section 1122 is tightly connected with the inner wall of the installation space 1131. Specifically, the plug section 1122 and the installation space 1131 have an interference fit or transition fit, so that the plug section 1122 is difficult to be pulled out of the installation space 1131, so that the needle body 112 and the handle 113 are stably connected.

[0072] Specifically, the plug section 1122 is a columnar structure. A plug hole 1133 is provided in the installation space 1131, and the shape and size of the plug hole 1133 correspond to the shape and size of the plug section 1122, so that when the plug section 1122 is inserted into the plug hole 1133, the plug section 1122 and the plug hole 1133 have an interference fit or transition fit, so that the needle body 112 and the handle 113 are tightly connected.

[0073] Furthermore, the plug-in section 1122 has a certain length, and the plug-in hole 1133 has a certain depth, so that when the plug-in section 1122 is inserted into the plug-in hole 1133, the contact area between the plug-in section 1122 and the plug-in hole 1133 is increased, so as to increase the connection tightness between the plug-in section 1122 and the plug-in hole 1133, and further make the needle body 112 and the handle 113 tightly connected.

[0074] In one embodiment, the plug hole 1133 includes a first end 1134 and a second end 1135, and the first end 1134 is arranged closer to the needle body 112 than the second end 1135. The diameter of the plug hole 1133 is successively reduced from the first end 1134 to the second end 1135, so that the plug hole 1133 forms a tapered hole structure. The shape and size of the plug section 1122 correspond to the shape and size of the plug hole 1133, and the plug hole 1133 and the plug section 1122 have an interference fit or transition fit, so that the plug section 1122 can be well inserted into the plug hole 1133. Because the plug section 1122 and the plug hole 1133 are both tapered structures, the plug section 1122 and the plug hole 1133 can limit each other, and further make the needle body 112 and the handle 113 tightly connected.

[0075] In addition, because the diameter of the second end 1135 of the plug-in hole 1133 is smaller than the diameter of the first end 1134, the remaining sections of the plug-in section 1122 except the plug-in end 1123 cannot pass through the second end 1135 of the plug-in hole 1133, so that the needle body 112 cannot further penetrate into the installation space 1131 of the handle 113, thereby maintaining the structural stability of the temperature measuring probe 100.

[0076] In a typical embodiment of the present invention, the plug end 1123 of the plug section 1122 is provided with a second opening 1124 of the blind hole 1121, and the side wall of the blind hole 1121 is bent from the second opening 1124 to form a flange 1125 at the second opening 1124. In this embodiment, the needle body 112 is made of a metal material, and in particular, it is recommended that the needle body 112 is made of a hard metal material, such as steel, so that the flange 1125 is not easily deformed and can continuously maintain structural stability, that is, the flange 1125 continuously maintains its own structural style and is not easily deformed. Preferably, the flange 1125 is processed by a spinning process.

[0077] A step 1136 is provided in the installation space 1131 corresponding to the flange 1125. The flange 1125 fits against the step 1136 so that the step 1136 limits the flange 1125, making it difficult for the plug-in section 1122 to be pulled out of the installation space 1131, further ensuring a stable connection between the needle body 112 and the handle 113, thereby maintaining the structural stability of the temperature measuring probe 100.

[0078] In this embodiment, the step 1136 is an inclined structure. Specifically, the inclined axis of the step 1136 is set at an acute angle to the central axis of the shell 110, so that when the flange 1125 is attached to the step 1136, the step 1136 can limit the flange 1125 and enhance the connection tightness between the needle body 112 and the handle 113.

[0079] In one embodiment, a transition hole 1137 is further provided in the installation space 1131, and the transition hole 1137 is connected to the second end 1135 of the plug hole 1133, and the transition hole 1137 is farther from the needle body 112 than the plug hole 1133. The step 1136 is the inner wall of the transition hole 1137. In other words, the inner wall of the transition hole 1137 constitutes the step 1136, and the flange 1125 fits the inner wall of the transition hole 1137. In this embodiment, the transition hole 1137 is a tapered hole structure, so that the inclined axis of the step 1136 is inclined relative to the central axis of the housing 110.

[0080] In one embodiment, in combination Figure 4 In the installation space 1131, the first charging positive and negative electrodes 122 and the plug-in section 1122 are respectively arranged at the two ends of the installation space 1131, and the first charging positive and negative electrodes 122 and the plug-in section 1122 are arranged at intervals. The space between the first charging positive and negative electrodes 122 and the plug-in section 1122 is called a sealed space 1138, that is, the first charging positive and negative electrodes 122 and the plug-in section 1122 jointly define a sealed space 1138 in the installation space 1131.

[0081] The sealed space 1138 is filled with waterproof glue, which fills the sealed space 1138, so that the sealed space 1138 is airtight, and external water vapor does not enter the narrow and long space 111 through the sealed space 1138, so as to protect the components of the temperature measuring probe 100. In this embodiment, the waterproof glue can also bond the plug section 1122 and the plug hole 1133, so that the needle body 112 and the handle 113 are stably connected, and the waterproof glue can also bond the flange 1125 and the step 1136, so as to further connect the needle body 112 and the handle 113 stably.

[0082] In a further embodiment, in combination Figure 7 and Fig.10 A sealing ring groove 1126 is also formed on the outer surface of the plug section 1122, and the sealing ring groove 1126 is recessed from the outer surface toward the blind hole 1121. The waterproof glue can flow into the sealing ring groove 1126 and fill the sealing ring groove to further make the needle body 112 and the handle 113 tightly connected and further waterproof.

[0083] In a further embodiment, the insulating sleeve 161 is disposed in the first pole 123 of the annular structure, and a glue groove 1139 is formed between the insulating sleeve 161 and the first pole 123, the glue groove 1139 is connected to the sealed space 1138, and glue is injected into the sealed space 1138 through the glue groove 1139, and the waterproof glue is formed after the glue solidifies. In this embodiment, the glue also fills the glue groove 1139, and after the glue solidifies, the waterproof glue bonds the insulating sleeve 161 and the first pole 123, so that the insulating sleeve 161 and the first pole 123 are relatively stably arranged, maintaining the structural stability of the temperature measuring probe 100.

[0084] In one embodiment, the temperature sensor 150 is disposed in the blind hole 1121 of the needle body 112, and the temperature sensor 150 is disposed at the bottom of the blind hole 1121. In other words, the temperature sensor 150 is disposed inside the tip of the needle body 112. The temperature sensor 150 is electrically connected to the first control unit 131, so that the first control unit 131 controls the temperature sensor 150 to detect the external temperature. Preferably, the main temperature sensing element of the temperature sensor 150 is a negative temperature coefficient thermistor.

[0085] In one embodiment, the temperature measuring probe 100 of the present invention is mainly used to detect the temperature of food. For example, when grilling food, the temperature measuring probe 100 is inserted into the food so that the user can monitor the food temperature in real time, such as when grilling meat.

[0086] The present invention further provides a charging stand 200 , which is used to charge the temperature measuring probe 100 described above.

[0087] Combination Fig.11 and Fig.12 The charging seat 200 includes an installation box 210, a charging circuit (the charging circuit is referred to as a second charging circuit 220) and charging positive and negative electrodes (the charging positive and negative electrodes are referred to as second charging positive and negative electrodes 230), the second charging circuit 220 and the second charging positive and negative electrodes 230 are arranged in the installation box 210, and the second charging circuit 220 is electrically connected to the second charging positive and negative electrodes 230.

[0088] In this embodiment, the second charging circuit 220 is also connected to a power source 240, and the power source 240 is a battery of the charging base 200 (the battery is referred to as a second battery 241), or the power source 240 is an external power source. When the power source 240 is the second battery 241, the second charging circuit 220 is electrically connected to the second battery 241. When the power source 240 is an external power source, the second charging circuit 220 is electrically connected to the external power source by leading out a cable of the charging base 200.

[0089] The second charging positive and negative electrode 230 includes a third electrode 231 and a fourth electrode 232, wherein one of the third electrode 231 and the fourth electrode 232 is a positive electrode and the other is a negative electrode. In this embodiment, the third electrode 231 is a negative electrode and the fourth electrode 232 is a positive electrode to describe the present invention, but this should not be construed as limiting the present invention.

[0090] When the temperature measuring probe 100 is charged through the charging base 200, the third pole 231 is electrically connected to the first pole 123 of the temperature measuring probe 100, and the fourth pole 232 is electrically connected to the second pole 124 of the temperature measuring probe 100. Current is transmitted to the third pole 231 and the fourth pole 232 through the second charging circuit 220 to charge the first battery 121 of the temperature measuring probe 100 through the second charging positive and negative electrodes 230.

[0091] In this embodiment, combined with Fig.13 and Fig.14, because the first pole 123 and the second pole 124 are arranged at the same end, the third pole 231 and the fourth pole 232 are also arranged at the same end, so that the third pole 231 and the fourth pole 232 are respectively electrically connected to the corresponding first pole 123 and the second pole 124. Moreover, because the third pole 231 and the fourth pole 232 are arranged at the same end, the charging stand 200 can optimize the structure, and there is no need to arrange the positive pole and the negative pole at different positions of the charging stand 200 like a traditional charging stand. Therefore, the charging stand 200 provided by the present invention is convenient for reasonable arrangement of components and simplified structure.

[0092] Combination Fig.14 The third pole 231 includes a contact sheet 2311, which is made of metal material. A notch 2312 is provided in the contact sheet 2311 to divide the contact sheet 2311 into two, forming two contact springs (the contact spring is called the first contact spring 2313), and the two first contact springs 2313 are arranged opposite to each other. The fourth pole 232 includes a contact spring (the contact spring is called the second contact spring 2321), the second contact spring 2321 is made of metal material, and the second contact spring 2321 is arranged in the notch 2312, that is, the second contact spring 2321 is arranged between the pair of first contact springs 2313, so that the second contact spring 2321 is insulated from the two first contact springs 2313.

[0093] When the second charging positive and negative electrodes 230 of the charging seat 200 are electrically connected to the first charging positive and negative electrodes 122 of the temperature measuring probe 100, the second contact spring 2321 elastically contacts the second electrode 124, so that the fourth electrode 232 and the second electrode 124 are electrically connected; because the first electrode 123 is an annular structure, and the second electrode 124 is arranged inside the first electrode 123, in order to avoid the third electrode 231 and the second electrode 124 being electrically connected, a pair of first contact springs 2313 of the third electrode 231 elastically contacts the two sides of the annular first electrode 123, so that the third electrode 231 and the first electrode 123 are electrically connected; thereby, the second charging positive and negative electrodes 230 and the first charging positive and negative electrodes 122 are electrically connected.

[0094] In one embodiment, the first contact spring 2313 and the second contact spring 2321 are both provided on contact protrusions, and are in contact with the first pole 123 and the second pole 124 through the contact protrusions.

In this embodiment, the clamping arm 2121 is a spring, and the clamping arm 2121 has an elastic force toward the other clamping arm 2121. In other words, the pair of clamping arms 2121 have opposite elastic forces, so that the pair of clamping arms can clamp the temperature measuring probe 100. In this embodiment, it is recommended that the pair of clamping arms 2121 clamp the needle body 112 of the temperature measuring probe 100.

[0097] In one embodiment, a limiting protrusion 213 is protruded from each of the two side walls of the receiving groove 211 to form a constriction in the receiving groove 211.

The spacing between the two limiting protrusions 213 is smaller than the width of the handle 113, so that the temperature measuring probe 100 is limited by the two limiting protrusions 213, so that the temperature measuring probe 100 cannot move along the axis of the receiving groove 211, and the temperature measuring probe 100 is stably arranged in the receiving groove 211.

[0098] In this embodiment, it is recommended that the pair of clamping arms 2121 are separately disposed on the two limiting protrusions 213 , so that the pair of clamping arms 2121 can clamp the temperature measuring probe 100 .

In this embodiment, the plurality of receiving grooves 211 are arranged in parallel to optimize the spatial arrangement of the installation box 210, so that the installation box 210 is miniaturized.
