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, temperature probes play a key role in ensuring that food is cooked to perfection. Their accuracy and convenience have a decisive impact on the taste and safety of food. In particular, the role of temperature probes is particularly prominent in delicate cooking processes such as barbecue and baking. In these occasions, the probes are carefully inserted into the food to monitor the temperature changes inside the food in real time to ensure that the food can be properly cooked or baked to the ideal state.

[0003] The design of traditional temperature probes usually consists of two parts: a metal needle and a handle. The metal needle, as the sensing part of the probe, is directly responsible for contacting the food and accurately capturing the temperature changes of the food. The handle is used by the chef to hold it, ensuring stability and convenience during use.

[0004] The connection between the metal needle body and the handle is usually a classic threaded connection. This connection is popular because of its simplicity and stability. However, in cooking practice, this connection also exposes some problems. Especially when handling foods containing corrosive ingredients, such as ingredients containing more acid, alkali and other substances, these corrosive substances will gradually corrode the threads at the connection between the metal needle body and the handle.

[0005] Long-term corrosion will cause the threaded part to rust, which not only affects the aesthetics of the temperature probe, but more importantly, it seriously weakens the connection strength between the metal needle body and the handle. The rusted thread will gradually lose its original fastening force, causing the connection to become loose. When this looseness reaches a certain degree, it will directly affect the overall structural stability of the temperature probe.

[0006] During the cooking process, an unstable temperature probe may suddenly shake or even fall off, which not only makes it impossible for the chef to accurately read the temperature data of the food, but also may cause unnecessary interference to the carefully prepared cooking process. More seriously, if the probe accidentally falls off during the cooking process, it may also cause safety accidents such as fire, posing a threat to the safety of chefs and diners. Therefore, how to improve the connection stability between the metal needle body and the handle of the temperature probe has become a technical problem that needs to be solved urgently. 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, comprising a shell, the shell including a needle body and a handle, a blind hole being provided inside the needle body, an installation space being provided inside the handle, the needle body including an insertion section, the opening of the blind hole being provided in the insertion section, the insertion section being inserted into the installation space, the insertion section being tightly fitted with an inner wall of the installation space of the handle, and the insertion section being provided with a flange extending outward, and the installation space being provided with a step fitting with the flange.

[0010] Furthermore, the flange is formed by bending the plug-in section corresponding to the opening position of the blind hole.

[0011] In one embodiment, the step is an inclined structure, and the inclination axis of the step is arranged at an acute angle to the central axis of the shell.

[0012] Furthermore, a plug-in hole and a transition hole that are interconnected are formed in the installation space, the plug-in section is inserted into the plug-in hole, the diameter of the plug-in hole is smaller than the diameter of the transition hole, and the step is formed on the inner wall of the transition hole.

[0013] Furthermore, the plug-in hole is a tapered hole, comprising a first end and a second end, the second end being connected to the transition hole, the aperture of the plug-in hole gradually decreases from the first end to the second end, and the shape and size of the plug-in section correspond to the shape and size of the plug-in hole.

[0014] Furthermore, the blind hole and the installation space together define a long and narrow space, and a control unit, a temperature sensor and a charging component are installed in the long and narrow space. The control unit is electrically connected to the temperature sensor and the charging component respectively.

[0015] Specifically, the charging component includes a battery and positive and negative charging electrodes, the battery is arranged in the blind hole, the positive and negative charging electrodes are arranged in the installation space, the positive and negative charging electrodes include a first pole and a second pole, the first pole is an annular structure, the second pole is a columnar structure, the first pole is sleeved with the second pole, the first pole and the second pole each lead out a charging wire to electrically connect the battery, and the handle is provided with openings corresponding to the positive and negative charging electrodes to expose the first pole and the second pole.

[0016] Furthermore, in the installation space, the positive and negative charging electrodes are spaced apart from the plug-in section and together define a sealed space, and the sealed space is filled with waterproof glue.

[0017] Specifically, a sealing ring groove is formed on the outer surface of the plug-in section, the sealing ring groove is recessed from the outer surface toward the blind hole, and the sealing ring groove is filled with waterproof glue.

[0018] Specifically, the needle body is made of metal material, and the handle is made of ceramic or plastic material.

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

[0020] First, in the temperature measuring probe of the utility model, the close fit between the plug-in section and the inner wall of the installation space significantly reduces the risk of loosening due to equipment vibration or improper operation. During the temperature measurement process, especially in a kitchen environment, the equipment may be subjected to varying degrees of vibration and impact. By ensuring that the plug-in section is in close contact with the inner wall of the installation space, the movement or deviation of the needle body caused by these external factors can be prevented, thereby ensuring the accuracy and stability of the temperature measuring probe. The close fit between the plug-in section and the inner wall of the installation space also helps prevent contaminants such as liquids or dust from entering the interior of the installation space, protecting the temperature measuring probe from external contaminants.

[0021] Secondly, the fit between the flange and the step not only enhances the connection strength between the needle body and the handle, but also provides additional safety. When the needle body is inserted into the handle, a strong locking structure is formed between the flange and the step. This locking structure can withstand external forces from all directions, including pulling force, pushing force, torsion force, etc., thereby effectively preventing the needle body from falling off or loosening during use.

[0022] Thirdly, the fit between the flange and the step also increases the surface area of ​​the connection interface. Compared with the traditional single plane contact, the contact area between the flange and the step is larger, which can disperse the pressure acting on the connection interface. This effect of dispersing pressure can reduce the risk of local stress concentration and further enhance the connection strength between the needle body and the handle.

[0023] Therefore, the fit between the flange and the step can maintain stable connection performance and resist erosion and wear from the external environment during long-term use or exposure to harsh environments. Therefore, even after long-term use or exposure to harsh environments, the connection between the needle body and the handle can still remain firm and reliable. This stability is crucial to ensure the accuracy and reliability of the temperature probe during long-term use or harsh environments. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0042] The utility model provides a temperature measuring probe, the needle body of the temperature measuring probe is tightly connected to a handle, and one end of the needle body is provided with a flange, which fits with a step in the handle to further enable the needle body to be tightly connected to the handle.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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 .

[0047] 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.

[0048] 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.

[0049] 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.

[0050] 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.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] In a typical embodiment of the present invention, 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.

[0061] 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.

[0063] 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.

[0064] 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.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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 short circuit caused by mutual connection of the first charging line 125 and the second charging line 126. 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.

[0071] 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.

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.

[0076] 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.

[0077] In this embodiment, combined with Figure 4 and Figure 6, the signal transmitting structure 143 is the first pole 123, and the signal line 144 is the first charging line 125. In other words, the antenna structure is composed of the first pole 123 and the first charging line 125, so that the temperature measuring probe 100 of the present invention does not need to be provided 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 first pole 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.

[0078] Specifically, for the convenience of the following description, the signal transmission structure 143 is collectively referred to as the first pole 123, and the signal line 144 is collectively referred to as the first charging line 125. The handle 113 is provided with the first opening 1132 corresponding to the first charging positive and negative poles 122, so that the first pole 123 can directly transmit signals to the outside without being shielded by other components of the temperature measuring probe 100, so as to improve the signal transmission efficiency of the antenna structure.

[0079] Because the first pole 123 and the second pole 124 are insulated from each other, the second pole 124 will not interfere with the external signal transmission of the first pole 123. 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, so as to prevent the second pole 124 from interfering with the signal of the first pole 123.

[0080] 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 first pole 123 disposed in its installation space 1131 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 charges the first battery 121, it will not be interfered by the handle 113, resulting in a decrease in charging efficiency or charging failure.

[0081] 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.

[0082] In one embodiment, in the antenna structure, the second pole 124 can also be used as the signal transmitting structure 143, and the second charging line 126 can be used as the signal line 144. For details on how the second pole 124 and the second charging line 126 constitute the antenna structure, please refer to the above text. To save space, it will not be repeated here.

[0083] In one 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, and 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.14The third pole 231 includes a contact piece 2311, which is made of metal material. A notch 2312 is provided in the contact piece 2311 to divide the contact piece 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), which is made of metal material and 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.

[0095] Combination Fig.13 The installation box 210 is provided with a receiving groove 211, and the receiving groove 211 is used to receive the temperature measuring probe 100. The second charging positive and negative electrodes 230 are arranged at one end of the receiving groove 211, so that when the temperature measuring probe 100 is placed in the receiving groove 211, the temperature measuring probe 100 can be charged.

[0096] The receiving groove 211 is also provided with a clamping mechanism 212, and the clamping mechanism 212 includes a pair of clamping arms 2121, and the pair of clamping arms 2121 are respectively provided on the two side walls of the receiving groove 211. When the temperature measuring probe 100 is placed in the receiving groove 211, the pair of clamping arms 2121 clamps a section of the axial direction of the temperature measuring probe 100 to fix the temperature measuring probe 100 in the receiving groove 211. 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 two limiting protrusions 213 are arranged correspondingly near the intersection of the needle body 112 and the handle 113 of the temperature measuring probe 100, and the two limiting protrusions 213 are arranged correspondingly on a section of the receiving groove 211 for accommodating the needle body 112. 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 .

[0099] In one embodiment, the installation box 210 is provided with a plurality of receiving grooves 211, and each receiving groove 211 is provided with a second charging positive and negative electrode 230, so that the installation box 210 can simultaneously accommodate a plurality of temperature measuring probes 100, and can simultaneously charge the plurality of temperature measuring probes 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.

The second control unit 250 is electrically connected to the second communication unit 260, the second charging circuit 220, the power supply 240 and the display unit 270 respectively.

[0101] Combination Figure 1 , Figure 2 and Fig.12 , the first communication unit 140 of the temperature measuring probe 100 can transmit signals with the second communication unit 260 of the charging stand 200, so that wireless communication is realized between the temperature measuring probe 100 and the charging stand 200. When the temperature measuring probe 100 is placed in the receiving groove 211 of the charging stand 200 for charging, after the first control unit 131 of the temperature measuring probe 100 obtains the power information of the first battery 121, the first control unit 131 sends the power information to the charging stand 200 via the first communication unit 140; the second control unit 250 of the charging stand 200 receives the power information sent by the temperature measuring probe 100 via the second communication unit 260, and after obtaining the power information, the second control unit 250 can display the power information via the display unit 270, so as to prompt the user, so that the user can know the power of the first battery 121 of the temperature measuring probe 100 in time. Preferably, the second communication unit 260 is an antenna component or a Bluetooth component or a WI FI component.
