Technical Field

[0001] This application relates to the field of temperature measuring device technology, and in particular to a temperature detection device, a charging device, and a temperature detection equipment. Background Technology

[0002] A food thermometer is a temperature measuring device used to measure the internal temperature of food or other objects. It is characterized by high accuracy and fast response. A food thermometer typically includes a connected probe and a handle, with the probe housing an electrically connected circuit board and a battery. Currently, the circuit board in food thermometers is located inside the probe, resulting in a larger and thicker probe, which is not conducive to inserting the probe into the food to measure its internal temperature. Therefore, this problem urgently needs to be solved. Utility Model Content

In summary, the above-described temperature detection device has the beneficial effect of being easily inserted into the interior of the object to be measured to measure the internal temperature of the object.

[0017] Furthermore, since the first and second conductive elements, which serve as the two charging electrodes of the temperature detection device, are both disposed on the second housing, the charging device used in conjunction with the temperature detection device can place the two power supply electrodes in the receiving groove for accommodating the second housing without the need to provide other structures at the positions corresponding to the first housing. This simplifies the structure of the charging device used in conjunction with the temperature detection device, reduces the size of the charging device, and lowers the production cost of the charging device.

Detailed Implementation

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort are within the scope of protection of the present application.

[0036] In the description of this application, it should be understood that the terms "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "inside", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the purpose of simplifying the description of this application and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0037] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0038] Furthermore, unless otherwise explicitly specified or limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or merely surface contact. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0039] If certain terms are used in the specification and claims to refer to specific components, those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. The specification and claims do not distinguish components based on differences in name, but rather on differences in function. For example, the term "comprising" used throughout the specification and claims is an open-ended term and should be interpreted as "including but not limited to"; "generally" means that those skilled in the art can solve the technical problem and basically achieve the technical effect within a certain margin of error.

[0040] Please see Figure 1 This application provides a temperature detection device 100, which is used to contact an object to be measured to obtain the temperature of the object. For example, the temperature detection device 100 may be a food temperature probe (e.g., a barbecue temperature probe, a hot pot temperature probe, etc.) or a household / industrial thermometer. The specific type and application scenario of the temperature detection device 100 are not limited.

[0041] Please see Figure 1 , Figure 2 and Figure 3 The temperature detection device 100 includes a first housing 10, a second housing 11, and a circuit board 12.

[0042] The first housing 10 is the main body of the temperature detection device 100, and it is generally elongated cylindrical. One end of the first housing 10 (i.e., the temperature measuring end 102 hereinafter) is generally conical in shape so that it can be more easily inserted into the interior of food or objects to obtain the internal temperature. The first housing 10 is provided with a first inner cavity 101, and the first housing 10 has a temperature measuring end 102 and a connecting end 103 that are opposite to each other. The temperature measuring end 102 is adapted to contact the object to be measured.

[0043] The second housing 11 is used by the user to hold and use the temperature detection device 100. The second housing 11 has a second inner cavity 111, which communicates with the first inner cavity 101. The second housing 11 includes a housing body 112, a first conductive element 113, and a second conductive element 114. The housing body 112 is the main part of the second housing 11 and is generally cylindrical. Both the first conductive element 113 and the second conductive element 114 are conductors and can be made of any conductive material such as stainless steel or copper. The materials of the first conductive element 113 and the second conductive element 114 can be the same or different. One end of the housing body 112 is connected to the connecting end 103. The first conductive element 113 and the second conductive element 114 are spaced apart and located at opposite ends of the housing body 112. It should be noted that "the first conductive element 113 and the second conductive element 114 are spaced apart" means that the first conductive element 113 and the second conductive element 114 are not in direct contact.

[0044] Circuit board 12 is disposed in the second inner cavity 111. Circuit board 12 has a first electrode contact and a second electrode contact (both not shown in the figure) with opposite polarities. The first electrode contact is electrically connected to a first conductive element 113, which is used to electrically connect to one electrode of the charging power supply 24 to receive electrical energy. That is, the first conductive element 113 serves as a charging electrode when the temperature detection device 100 is charging. The second electrode contact is electrically connected to a second conductive element 114, which is used to electrically connect to the other electrode of the charging power supply 24 to receive electrical energy. That is, the second conductive element 114 serves as the other charging electrode when the temperature detection device 100 is charging. The charging power supply 24 is an external power source 24, and the first conductive element 113 and the second conductive element 114 are respectively used to electrically connect to the two electrodes of the charging power supply 24.

[0045] With the above configuration, when the first conductive element 113 and the second conductive element 114 are electrically connected to the two electrodes of the charging power supply 24, a closed charging circuit can be formed between the charging power supply 24 and the circuit board 12 to charge the temperature detection device 100. Furthermore, since the circuit board 12 is located inside the second housing 11, the first housing 10, which contacts the object to be measured, can be made smaller and thinner, making it easier to insert the first housing 10 into the object to measure its internal temperature. Further, since the first conductive element 113 and the second conductive element 114, which serve as the two charging electrodes of the temperature detection device 100, are both located on the second housing 11, the charging device 200 used in conjunction with the temperature detection device 100 can have its two power supply electrodes located in the receiving groove 211 for accommodating the second housing 11, without needing to have other structures corresponding to the first housing 10. This simplifies the structure of the charging device 200 used with the temperature detection device 100, reduces its size, and lowers its production cost.

[0046] In some embodiments, the temperature detection device 100 further includes a battery 20, which is housed in the first inner cavity 101 and located at the connection end 103. The battery 20 is connected to the circuit board 12 and is electrically connected to both the first electrode contact and the second electrode contact. With this configuration, since the battery 20 is electrically connected to both the first and second electrode contacts, when the first conductive element 113 and the second conductive element 114 are respectively electrically connected to the two electrodes of the charging power supply 24, a closed charging circuit can be formed between the charging power supply 24, the circuit board 12, and the battery 20 to charge the battery 20 of the temperature detection device 100.

[0047] In some embodiments, the first housing 10 includes a coaxial and connected first segment 104 and a second segment 105. Both the first segment 104 and the second segment 105 are part of the structure of the first housing 10, and both are generally cylindrical. One end of the first segment 104 is connected to one end of the second segment 105. The temperature measuring end 102 is located at the end of the first segment 104 away from the second segment 105, and the connecting end 103 is located at the end of the second segment 105 away from the first segment 104. The inner diameter of the second segment 105 is larger than the inner diameter of the first segment 104, and the battery 20 is housed inside the second segment 105. With this arrangement, since the battery 20 is relatively large, placing it inside the second segment 105 with its larger inner diameter, while setting the first segment 104 to a smaller inner diameter, facilitates the user's simple and convenient operation when measuring the internal temperature of an object by inserting the smaller first end into the object.

[0048] In some embodiments, the housing body 112 is an insulator; for example, the housing body 112 may be a housing made of any insulating material such as ceramic or plastic. A first conductive element 113 is connected between the housing body 112 and the first housing 10, and at least a portion of the structure of the first conductive element 113 is exposed in the second inner cavity 111. A second conductive element 114 is connected to the end of the housing body 112 away from the first housing 10, and at least a portion of the structure of the second conductive element 114 is exposed in the second inner cavity 111.

[0049] With the above configuration, since at least a portion of the structure of the first conductive element 113 is exposed in the second inner cavity 111, it facilitates contact between the first conductive element 113 and one electrode of the charging power supply 24 during charging. Since at least a portion of the structure of the second conductive element 114 is exposed in the second inner cavity 111, it facilitates contact between the second conductive element 114 and the other electrode of the charging power supply 24 during charging. Because the first conductive element 113 and the second conductive element 114 are located at opposite ends of the housing body 112 made of insulating material, they are separated by the housing body 112. This prevents accidental contact between the first conductive element 113 and the second conductive element 114, thus avoiding a short circuit in the charging circuit and improving charging safety.

[0050] Please see Figure 2 and Figure 3 In some embodiments, the housing body 112 includes a first connecting segment 1121 located at its end. The first connecting segment 1121 is a part of the structure of the housing body 112 and is generally cylindrical. The first conductive element 113 includes a first contact portion 1131 and a first connecting portion 1132 connected together. The first contact portion 1131 is the part of the first conductive element 113 used to directly contact an electrode of the charging power supply 24 to achieve an electrical connection. The first contact portion 1131 may be generally annular (see [reference]). Figure 3 ) or cylindrical (see Figure 6 and Figure 9The first connecting portion 1132 is the part of the first conductive element 113 used to connect with the first connecting segment 1121 of the housing body 112. The first connecting portion 1132 is generally cylindrical. The first connecting portion 1132 and the first connecting segment 1121 are nested and connected. As a specific example, in this embodiment, the first connecting segment 1121 is sleeved on the outer periphery of the first connecting portion 1132, and the first connecting segment 1121 and the first connecting portion 1132 are connected by a threaded fit. In other embodiments, the first connecting portion 1132 may also be sleeved on the outer periphery of the first connecting segment 1121, and the first connecting segment 1121 and the first connecting portion 1132 may also be connected by any other means such as an interference fit or a snap fit. The radial dimension of the first conductive portion 1131 is larger than the radial dimension of the first connecting portion 1132. The first connecting segment 1121 is provided with a first port 1123, and at least a portion of the structure of the first conductive portion 1131 is exposed to the second inner cavity 111 through the first port 1123. It should be noted that "at least a portion of the structure of the first electrical contact 1131 is exposed in the second inner cavity 111 via the first port 1123" includes at least the following situations: the first electrical contact 1131 is completely located inside the second inner cavity 111; at least a portion of the structure of the first electrical contact 1131 passes through the first port 1123 and extends outside the second inner cavity 111; at least a portion of the structure of the first electrical contact 1131 is flush with the first port 1123.

[0051] With the above configuration, the first connecting portion 1132 of the first conductive element 113 is used to connect with the first connecting section 1121 of the housing body 112, so as to realize the connection between the first conductive element 113 and the housing body 112. Furthermore, at least a portion of the structure of the first contact portion 1131 of the first conductive element 113 is exposed to the second inner cavity 111 via the first port 1123 of the first connecting section 1121, which facilitates the first conductive element 113 to contact one electrode of the charging power supply 24 to achieve electrical connection, thereby facilitating the charging power supply 24 to charge the temperature detection device 100.

[0052] Please see Figure 2 and Figure 3 In some embodiments, the housing body 112 includes a second connecting section 1122 located at its end. The second connecting section 1122 is a part of the structure of the housing body 112 and is generally cylindrical. The second conductive member 114 includes a connected second contact portion 1141 and a second connecting portion 1142. The second contact portion 1141 is the part of the second conductive member 114 used to directly contact an electrode of the charging power supply 24 to achieve an electrical connection. The second contact portion 1141 may be generally disc-shaped (see...). Figure 3 and Figure 9 ) or cylindrical (see Figure 6The second connecting portion 1142 is the part of the second conductive member 114 used to connect with the second connecting section 1122 of the housing body 112. The second connecting portion 1142 is generally cylindrical (see...). Figure 6 ) or cylindrical (see Figure 3 and Figure 9 The second connecting portion 1142 is nested and connected to the second connecting segment 1122. In this embodiment, the second connecting segment 1122 is sleeved on the outer periphery of the second connecting portion 1142, and the second connecting segment 1122 and the second connecting portion 1142 are threaded together. In other embodiments, the second connecting portion 1142 may be sleeved on the outer periphery of the first connecting segment 1121, and the second connecting segment 1122 and the second connecting portion 1142 may be connected by any other means such as interference fit or snap fit. The radial dimension of the second electrical contact portion 1141 is larger than the radial dimension of the second connecting portion 1142, and the second connecting segment 1122 is provided with a second port 1124. At least a portion of the structure of the second electrical contact portion 1141 is exposed to the second inner cavity 111 through the second port 1124. It should be noted that "at least a portion of the structure of the second electrical contact 1141 is exposed in the second inner cavity 111 via the second port 1124" includes at least the following situations: the second electrical contact 1141 is completely located inside the second inner cavity 111; at least a portion of the structure of the second electrical contact 1141 passes through the second port 1124 and extends outside the second inner cavity 111; at least a portion of the structure of the second electrical contact 1141 is flush with the second port 1124.

[0053] With the above configuration, the second connecting portion 1142 of the second conductive member 114 is used to connect with the second connecting section 1122 of the housing body 112 to realize the connection between the second conductive member 114 and the housing body 112. Furthermore, at least a portion of the structure of the second contact portion 1141 of the second conductive member 114 is exposed to the second inner cavity 111 via the second port 1124 of the second connecting section 1122, which facilitates the contact between the second conductive member 114 and the other electrode of the charging power supply 24 to achieve electrical connection, thereby facilitating the charging power supply 24 to charge the temperature detection device 100.

[0054] Please see Figure 3In some embodiments, the first conductive element 113 is provided with a first contact cavity 1133, which communicates with the first inner cavity 101. The first contact cavity 1133 is part of the second inner cavity 111, and may be defined by a first contact portion 1131 and a first connecting portion 1132. The temperature detection device 100 also includes a first conductive elastic element 13. The first conductive elastic element 13 is a conductor and has elasticity. The first conductive elastic element 13 is disposed on the circuit board 12 and elastically abuts against the inner wall of the first contact cavity 1133, and is electrically connected to the first electrode contact. It should be noted that "the first conductive elastic element 13 elastically abuts against the inner wall of the first contact cavity 1133" means that the portion of the structure where the first conductive elastic element 13 abuts against the inner wall of the first contact cavity 1133 can undergo elastic deformation, or that this portion of the structure abutting against the inner wall of the first conductive elastic element 13 has a tendency to move closer to the inner wall of the first contact cavity 1133 under the action of other elastic elements. For example, this portion of the structure where the first conductive elastic element 13 abuts against the inner wall of the first contact cavity 1133 can be an elastic metal sheet, or this portion of the structure where the first conductive elastic element 13 abuts against the inner wall of the first contact cavity 1133 can be in stable contact with the inner wall of the first contact cavity 1133 under the elastic force of a spring. As a specific example, in this embodiment, the first conductive elastic element 13 is a conductive spring needle. In other embodiments, the first conductive elastic element 13 can also be any structure such as a conductive sheet or a conductive spring. With the above configuration, the first conductive elastic element 13 can achieve electrical connection between the first conductive element 113 and the first electrode contact, so that the first conductive element 113 can be used as a charging electrode of the temperature detection device 100.

[0055] In some embodiments, the number of first conductive elastic elements 13 is multiple, and multiple first conductive elastic elements 13 are provided on both opposite sides of the circuit board 12. As a specific example, in this embodiment, two first conductive elastic elements 13 are provided, and the two first conductive elastic elements 13 are respectively located on opposite sides of the circuit board 12. In other embodiments, the number of first conductive elastic elements 13 can also be three, four, five, or any other number. With the above arrangement, since multiple first conductive elastic elements 13 are provided, when one first conductive elastic element 13 has poor contact with the first conductive element 113, the other first conductive elastic elements 13 can still ensure stable conduction between the circuit board 12 and the first conductive element 113, thus improving the stability of charging. In addition, the first conductive elastic elements 13 located on both sides of the circuit board 12 abut against the inner wall of the first conductive element 113, which not only plays a conductive role, but also supports and fixes the circuit board 12. Therefore, there is no need to set an additional fixing structure for the circuit board 12, which simplifies the structure and reduces the size.

[0056] Please see Figure 2 and Figure 3 In some embodiments, the connecting end 103 of the first housing 10 is inserted into the first electrical contact cavity 1133 and connected to the first conductive element 113. Specifically, the end of the second segment 105 of the first housing 10 away from the first segment 104 is inserted into the first electrical contact cavity 1133 and connected to the first conductive element 113. Through the above arrangement, the first inner cavity 101 communicates with the first node cavity, and the battery 20 located in the second segment 105 can contact and connect with the circuit board 12 located in the second inner cavity 111. The connection method between the second end of the first housing 10 and the first conductive element 113 can be any type of connection method such as threaded connection, adhesive bonding, or snap-fit ​​connection; there is no limitation on this.

[0057] In some embodiments, the temperature detection device 100 further includes a first sealing ring (not shown in the figure), which is generally annular and may be made of elastic material such as a rubber ring or silicone ring. The inner wall of the first electrical contact cavity 1133 is provided with a first annular groove (not shown in the figure), which is also generally annular. The first sealing ring is embedded in the first annular groove and fitted around the outer periphery of the connecting end 103 of the first housing 10. The first sealing ring is clamped together by the inner bottom wall of the first annular groove and the outer wall of the first housing 10. Through this arrangement, the inner bottom wall of the first annular groove and the outer wall of the first housing 10 clamp the first sealing ring to form a sealing structure. This sealing structure can prevent water from outside the temperature detection device 100 from entering the first inner cavity 101 and the second inner cavity 111 through the connection gap between the first housing 10 and the first conductive element 113, thereby improving the waterproof performance and safety of the temperature detection device 100.

[0058] Please see Figure 4 , Figure 5 and Figure 6In some embodiments, the second connecting portion 1142 is inserted into the interior of the second connecting segment 1122. The second conductive member 114 has a second contact cavity 1143, which is part of the second inner cavity 111. The second contact cavity 1143 may be defined by the second contact portion 1141 and the second connecting portion 1142. The temperature detection device 100 also includes a second conductive elastic member 14. The second conductive elastic member 14 is a conductor and has elasticity. The second conductive elastic member 14 is disposed on the circuit board 12 and elastically abuts against the inner wall of the second contact cavity 1143. The second conductive elastic member 14 is electrically connected to the second electrode contact. It should be noted that "the second conductive elastic element 14 elastically abuts against the inner wall of the second contact cavity 1143" means that the portion of the structure where the second conductive elastic element 14 abuts against the inner wall of the second contact cavity 1143 can undergo elastic deformation, or that this portion of the structure abutting against the inner wall of the second conductive elastic element 14 has a tendency to move closer to the inner wall of the second contact cavity 1143 under the action of other elastic elements. For example, this portion of the structure where the second conductive elastic element 14 abuts against the inner wall of the second contact cavity 1143 can be an elastic metal sheet, or this portion of the structure where the second conductive elastic element 14 abuts against the inner wall of the second contact cavity 1143 can be in stable contact with the inner wall of the second contact cavity 1143 under the elastic force of a spring. As a specific example, in this embodiment, the second conductive elastic element 14 is a conductive spring needle. In other embodiments, the second conductive elastic element 14 can also be any structure such as a conductive sheet or a conductive spring. With the above configuration, the second conductive elastic element 14 can realize the electrical connection between the first conductive element 113 and the first electrode contact, so that the second conductive element 114 can be used as a charging electrode of the temperature detection device 100.

[0059] In some embodiments, there are multiple second conductive elastic elements 14, which are provided on opposite sides of the circuit board 12. As a specific example, in this embodiment, there are two second conductive elastic elements 14, which are respectively located on opposite sides of the circuit board 12. In other embodiments, the number of second conductive elastic elements 14 can be any number, such as three, four, or five. With the above arrangement, since there are multiple second conductive elastic elements 14, when one second conductive elastic element 14 has poor contact with the second conductive element 114, the other second conductive elastic elements 14 can still ensure stable conduction between the circuit board 12 and the second conductive element 114, thus improving the stability of charging. In addition, the second conductive elastic elements 14 located on both sides of the circuit board 12 abut against the inner wall of the second conductive element 114, which not only provides conductivity but also supports and fixes the circuit board 12. Therefore, there is no need to set up an additional fixing structure for the circuit board 12, which simplifies the structure and reduces the size.

[0060] In some embodiments, the temperature detection device 100 further includes a second sealing ring (not shown in the figure), which is generally annular and may be made of elastic material such as a rubber ring or a silicone ring. The outer wall of the second connecting portion 1142 is provided with a second annular groove (not shown in the figure), which is also generally annular. The second sealing ring is embedded in the second annular groove and fitted around the outer periphery of the second connecting portion 1142. The second sealing ring is clamped by the inner bottom wall of the second annular groove and the inner side wall of the second electrical contact cavity 1143. Through this arrangement, the inner bottom wall of the second annular groove and the inner side wall of the second electrical contact cavity 1143 clamp the second sealing ring to form a sealing structure. This sealing structure can prevent water from outside the temperature detection device 100 from entering the second inner cavity 111 through the connection gap between the housing body 112 and the second conductive element 114, thereby improving the waterproof performance and safety of the temperature detection device 100.

[0061] Please see Figure 7 , Figure 8 and Figure 9 In some embodiments, the second connecting portion 1142 is inserted into the interior of the second connecting segment 1122. For example, at least a portion of the inner wall of the second connecting segment 1122 is provided with a first internal thread segment (not shown in the figure), and the outer wall of the second connecting portion 1142 is provided with a first external thread segment (not shown in the figure) adapted to the first internal thread segment. The first internal thread segment and the first external thread segment mesh, that is, the second connecting portion 1142 and the second connecting segment 1122 are threadedly connected. The end face of the second connecting portion 1142 facing the circuit board 12 is provided with a connecting hole 1144. The connecting hole 1144 is a circular hole structure, and at least a portion of the inner wall of the connecting hole 1144 is provided with a second internal thread segment (not shown in the figure). The helical direction and pitch of the second internal thread segment and the first internal thread segment are the same. The temperature detection device 100 also includes a conductive connector 15. The conductive connector 15 is made of a conductive material, such as stainless steel, copper, aluminum, etc. The conductive connector 15 is generally elongated. One end of the conductive connector 15 is electrically connected to the second electrode contact. For example, one end of the conductive connector 15 can be directly or indirectly welded to the second electrode contact. The other end of the conductive connector 15 is inserted into the connecting hole 1144 and contacts the wall of the connecting hole 1144. The outer wall of the end of the conductive connector 15 away from the circuit board 12 is provided with a second external thread section (not shown in the figure) that matches the second internal thread section inside the connecting hole 1144. The second internal thread section and the second external thread section engage, that is, the end of the conductive connector 15 away from the circuit board 12 is threadedly engaged with the connecting hole 1144.

[0062] Through the above configuration, the conductive connector 15 is used to achieve an electrical connection between the second electrode contact and the second conductive element 114, so that the second conductive element 114 can be used as a charging electrode of the temperature detection device 100. Furthermore, since the helical direction and pitch of the first internal thread segment and the second internal thread segment are the same, and the helical direction and pitch of the first external thread segment and the second external thread segment are also the same, when the operator screws the second connecting portion 1142 of the second conductive element 114 into the second connecting segment 1122, the end of the conductive connector 15 away from the circuit board 12 can be screwed into the connecting hole 1144 to achieve an electrical connection between the conductive connector 15 and the second conductive element 114. In summary, while connecting the second conductive element 114 to the housing body 112, the operator can also achieve an electrical connection between the conductive connector 15 and the second conductive element 114, thereby simplifying the assembly steps of the temperature detection device 100 and improving assembly efficiency. Furthermore, the threaded connection between the conductive connector 15 and the second conductive component 114 can improve the stability of their connection, thereby ensuring a stable electrical connection between them.

[0063] In some embodiments, the conductive connector 15 is provided with a receiving through hole 151. The temperature detection device 100 also includes a first temperature sensor 16 and a first wire 17. The first temperature sensor 16 is disposed in the connection hole 1144, and the first wire 17 is electrically connected between the first temperature sensor 16 and the circuit board 12. The first wire 17 passes through the receiving through hole 151. With the above arrangement, the first temperature sensor 16 is located at the end of the temperature detection device 100 away from the temperature measuring part (i.e., the temperature measuring end 102 of the first housing 10), and it is used to detect the ambient temperature. The first wire 17 connected to it passes through the receiving through hole 151 of the conductive connector 15 and is electrically connected to the circuit board 12, which can facilitate wiring, save space, and reduce the volume of the second housing 11.

[0064] In some embodiments, the temperature detection device 100 further includes a second temperature sensor 18 and a second wire 19. The second temperature sensor 18 is disposed in the first inner cavity 101 and located at the temperature measuring end 102. The second wire 19 passes through the first inner cavity 101 and is electrically connected between the second temperature sensor 18 and the circuit board 12. With the above configuration, when the user uses the temperature detection device 100, by contacting the temperature measuring end 102 of the first housing 10 with the object to be measured, and with the second temperature sensor 18 located at the temperature measuring end 102, the temperature of the object to be measured can be quickly obtained, thereby realizing the rapid temperature measurement function.

[0065] Please see Figure 10 , Figure 11 and Figure 12Embodiments of this application also provide a charging device 200 for charging the temperature detection device 100 described above. The charging device 200 includes a charging base 21, a first electrode 22, a second electrode 23, and a power supply 24.

[0066] The charging base 21 is used to store the temperature detection device 100 and simultaneously charge it. The charging base 21 has a receiving groove 211 for accommodating the second housing 11 of the temperature detection device 100. The receiving groove 211 extends to one side of the charging base 21 and communicates with the outside of the charging base 21, so that the first housing 10 of the temperature detection device 100 extends beyond the receiving groove 211 from the aforementioned position. A first electrode 22 is disposed within the receiving groove 211 and is used to contact the first conductive element 113 of the temperature detection device 100 to achieve electrical connection. A second electrode 23 is disposed within the receiving groove 211 and is used to contact the second conductive element 114 of the temperature detection device 100 to achieve electrical connection. The first electrode 22 and the second electrode 23 can be conductors of any shape, such as spring-shaped, patch-shaped, or claw-shaped, and their shapes and structures can be the same or different. The power supply 24 can be used as a charging power supply for the temperature detection device 100. The power supply 24 is disposed on the charging base 21. The positive terminal of the power supply 24 is electrically connected to one of the first electrode 22 and the second electrode 23, and the negative terminal of the power supply 24 is electrically connected to the other of the first electrode 22 and the second electrode 23.

[0067] With the above configuration, when the second housing 11 of the temperature detection device 100 is placed in the receiving groove 211, the first conductive element 113 is electrically connected to the first electrode 22, and the second conductive element 114 is electrically connected to the second electrode 23, thereby forming a closed charging circuit between the power supply 24 and the circuit board 12 to charge the temperature detection device 100. Since the charging base 21 of the charging device 200 is only provided with the receiving groove 211 for accommodating the second housing 11, and no other structures or components are required for electrical connection with the first housing 10, the volume of the charging base 21 can be reduced, thereby reducing the overall volume of the charging device 200 and saving material costs.

[0068] In some embodiments, the charging device 200 further includes a cover 25, which is connected to the charging base 21 and covers the receiving slot 211. The cover 25 can be detached from the charging base 21 to fully expose the receiving slot 211. The cover 25 can also be rotatably connected to the charging base 21 and can rotate relative to the charging base 21 to fully expose the receiving slot 211. With the above configuration, when the charging device 200 charges the temperature detection device 100, the cover 25 can protect the second housing 11 to ensure stable charging operation.

[0069] Please see Figure 12 and Figure 13 This application also provides a temperature detection device 300, which includes the aforementioned temperature detection device 100 and a charging device 200. The second housing 11 of the temperature detection device 100 is embedded in the receiving groove 211 of the charging device 200. With the above arrangement, when the second housing 11 of the temperature detection device 100 is removed from the receiving groove 211 of the charging device 200, the user can use the temperature detection device 100 to measure the temperature of an object. When the second housing 11 of the temperature detection device 100 is placed in the receiving groove 211 of the charging device 200, the charging device 200 can charge the temperature detection device 100 so that the user can use the temperature detection device 100 next time.
