DETAILED DESCRIPTION
[0027] In order 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 in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the present application.
[0028] In the description of the present application, it should be understood that the terms "length", "width", "thickness", "up", "down", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or state relationships based on the positions or state relationships shown in the drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.
[0029] In addition, some of the above terms may be used to express other meanings in addition to indicating a position or state relationship. For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to specific circumstances.
[0030] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0031] In addition, unless otherwise expressly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be internal communication between two elements, or it can be only surface contact. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0032] If certain words are used in the specification and claims to refer to specific components, those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use differences in names as a way to distinguish components, but use differences in components' functions as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to"; "substantially" means that those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
[0033] See also Figure 1The embodiment of the present application provides a temperature detection device 100, which is used to contact with an object to be measured to obtain the temperature of the object to be measured. For example, the temperature detection device 100 can be a food temperature probe (barbecue temperature probe, hot pot temperature probe), or a household / industrial thermometer. There is no limitation on the specific type and usage scenario of the temperature detection device 100.
[0034] Please also see Figure 1 , Figure 2 and Figure 3 The temperature detection device 100 includes a first housing 10, a second housing 11, a circuit board 12, and an antenna 13. The first housing 10 is the main body of the temperature detection device 100. The first housing 10 is a conductor. The first housing 10 is provided with a first inner cavity 103. The first housing 10 has a first end 101 and a second end 102 which are opposite to each other. The first end 101 is suitable for contacting with the object to be detected. The second housing 11 is connected to the second end 102. The second housing 11 is provided with a second inner cavity 111 (see Figure 5 ), the second inner cavity 111 penetrates the surface of the second shell 11 and communicates with the outside, and communicates with the first inner cavity 103. When using the temperature detection device 100, the user can hold part of the second shell 11 and contact the first end 101 of the first shell 10 with the object to be measured to obtain the temperature of the object to be measured.
[0035] The circuit board 12 is disposed in the first inner cavity 103. The circuit board 12 has a first electrode contact and a second electrode contact (not shown in the figure) with opposite polarities. The first electrode contact is electrically connected to the first shell 10, so as to be electrically connected to the first electrode of the charging power source through the first shell 10. The charging power source is an external power source, and the first electrode is the positive electrode or negative electrode of the charging power source.
[0036] The antenna 13 is used to realize the communication connection between the temperature detection device 100 and other electronic devices. The antenna 13 is at least partially arranged in the second inner cavity 111. One end of the antenna 13 is electrically connected to the second electrode contact of the circuit board 12, and the other end is exposed to the outside through the second inner cavity 111. The antenna 13 is suitable for being electrically connected to the second electrode of the charging power supply. Among them, the second electrode is the negative electrode or the positive electrode of the charging power supply. When the first electrode is the positive electrode, the second electrode is the negative electrode, and when the first electrode is the negative electrode, the second electrode is the positive electrode.
[0037] Through the above arrangement, when the user needs to charge the temperature detection device 100, it is only necessary to electrically connect the first shell 10 and the antenna 13 to the first electrode and the second electrode of the charging power supply respectively, which is convenient to operate. Since the antenna 13 can be used as a charging electrode, the temperature detection device 100 can save the trouble of setting a charging electrode, so it can simplify its own structure and reduce its own volume. In addition, since at least part of the structure of the antenna 13 is exposed to the outside world, it can also effectively enhance the signal strength of the antenna 13 and improve the communication quality. In summary, the temperature detection device 100 has the beneficial effects of simplified structure, compact size, and strong communication quality.
[0038] Please also see Figure 1 and Figure 2 In some embodiments, the temperature detection device 100 further includes a first temperature sensing probe and a first wire (not shown in the figure). The first temperature sensing probe is disposed in the first inner cavity 103 and is located at the first end 101. The first temperature sensing probe is electrically connected to the circuit board 12 through the first wire. With the above arrangement, when the user uses the temperature detection device 100, the first end 101 of the first housing 10 is in contact with the object to be measured. The first temperature sensing probe is located at the first end 101, and the temperature of the object to be measured can be quickly obtained to realize the temperature measurement function.
[0039] In some embodiments, the first shell 10 includes a main body 104 and a temperature measuring part 105. The main body 104 is the main part of the first shell 10. As a specific example, in this embodiment, the main body 104 is roughly cylindrical and has a central axis O, which is roughly the same as the length direction X of the first shell 10. The temperature measuring part 105 is the part of the first shell 10 that contacts the object to be measured when measuring the temperature. The temperature measuring part 105 is provided with a temperature measuring cavity 107, and the main body 104 is provided with a containing cavity 106. The temperature measuring part 105 is connected to one end of the main body 104, and the temperature measuring cavity 107 is connected to the containing cavity 106 to jointly form the first cavity 103. The temperature measuring part 105 is located at the first end 101, and the first temperature sensing probe is located in the temperature measuring cavity 107. Through the above arrangement, when the user uses the temperature detection device 100, the temperature measuring part 105 of the first shell 10 is brought into contact with the object to be measured, and the first temperature sensing probe located in the temperature measuring inner cavity 107 can obtain the temperature of the object to be measured, thereby realizing the temperature measurement function. In addition, since the user holds the second shell 11, the main body 104 is also provided between the second shell 11 and the temperature measuring part 105, so that the user's hand can be separated from the object to be measured by a certain distance, so as to prevent the user from being scalded or frozen by the object to be measured.
[0040] In some embodiments, the outer diameter of the temperature measuring portion 105 gradually decreases from the end close to the main body 104 to the end away from the main body 104, and the end of the temperature measuring portion 105 away from the main body 104 is a temperature measuring tip for contacting the object to be measured. Through the above configuration, the end of the temperature measuring portion 105 away from the main body 104 is configured to be pointed, which can facilitate the temperature measuring portion 105 to be inserted into the interior of the object to be measured to obtain the internal temperature of the object.
[0041] In some embodiments, the temperature measuring cavity 107 is filled with a thermally conductive colloid (not shown in the figure), which is wrapped around the first temperature sensing probe and contacts the inner wall of the temperature measuring cavity 107. Through the above arrangement, the thermally conductive colloid can not only fix the first temperature sensing probe, but also improve the heat transfer efficiency between the temperature measuring part 105 and the first temperature sensing probe, thereby improving the accuracy of the temperature measurement result.
[0042] Please also see Figure 3 and Figure 4 In some embodiments, the temperature detection device 100 further includes a conductive spring 14, which is disposed on the circuit board 12 and elastically abuts against the inner wall of the first shell 10. The conductive spring 14 is used to realize the electrical connection between the first shell 10 and the circuit board 12. In some other embodiments, the number of the conductive springs 14 is multiple, and the multiple conductive springs 14 are disposed on opposite sides of the circuit board 12. Through the above arrangement, since there are multiple conductive springs 14, when a certain conductive spring 14 is in poor contact with the first shell 10, other conductive springs 14 can also ensure the stable conduction between the circuit board 12 and the first shell 10, so the charging stability can be improved; in addition, the conductive springs 14 located on both sides of the circuit board 12 are respectively abutted against the inner wall of the first shell 10, which can not only play a conductive role, but also support and fix the circuit board 12, so there is no need to set a separate fixing structure of the circuit board 12, which plays a role in simplifying the structure and reducing the volume.
[0043] In some embodiments, at least two conductive springs 14 are provided on opposite sides of the circuit board 12, and at least two conductive springs 14 on the same side of the circuit board 12 are spaced apart along the length direction X of the first shell 10. As a specific example, in this embodiment, two conductive springs 14 are provided on opposite sides of the circuit board 12. In other embodiments, three, four, five, or any other number of conductive springs 14 can be provided on opposite sides of the circuit board 12. In addition, the number of conductive springs 14 on both sides of the circuit board 12 can also be different, and there is no limitation on this. Through the above arrangement, the multiple conductive springs 14 on both sides of the circuit board 12 can not only form multiple contact points with the first shell 10 to ensure the stability of the power connection, but also improve the supporting and fixing effect on the circuit board 12.
[0044] In some embodiments, the conductive spring 14 includes a base 141 and a supporting arm 142. The base 141 is used to install and support the supporting arm 142, and the base 141 is electrically connected to the first electrode contact. For example, the base 141 can be directly or indirectly welded to the first electrode contact. One end of the supporting arm 142 is connected to the base 141, and the other end is suspended. At least part of the structure of the supporting arm 142 elastically supports the inner wall of the first shell 10. Through the above arrangement, the supporting arm 142 contacts the inner wall of the first shell 10, so the electrical connection between the first shell 10 and the first electrode contact on the circuit board 12 can be achieved; and because the supporting arm 142 elastically supports the inner wall of the first shell 10, the elastic force generated by the conductive spring 14 on the opposite sides of the circuit board 12 acts on the circuit board 12 at the same time to clamp the circuit board 12.
[0045] In some embodiments, the base 141 includes a bottom plate 1411 and two protective plates 1412, the bottom plate 1411 is attached to the circuit board 12, and is electrically connected to the first electrode contact. The protective plate 1412 is connected to the bottom plate 1411, the two protective plates 1412 are relatively spaced apart, and the supporting arm 142 is at least partially located between the two protective plates 1412. As a specific example, in this embodiment, the protective plate 1412 is substantially parallel to the length direction X of the first shell 10, and in other embodiments, the protective plate 1412 may also intersect with the length direction X of the first shell 10. Through the above arrangement, when the circuit board 12 equipped with the conductive spring sheet 14 is installed and inserted into the first inner cavity 103, the supporting arm 142 will encounter friction resistance when contacting the inner wall of the first inner cavity 103, thereby causing the supporting arm 142 to deform and displace. However, since at least part of the structure of the supporting arm 142 is located between the two protective plates 1412, the two protective plates 1412 can limit the supporting arm 142, thereby limiting the displacement range of the supporting arm 142 to ensure that the supporting arm 142 can always be in stable contact with the inner wall of the first inner cavity 103.
[0046] In some embodiments, the supporting arm 142 is a bent spring structure, one end of the supporting arm 142 is connected to the bottom plate 1411, and the other end is bent and extended in a direction away from the bottom plate 1411. The conductive spring 14 also includes a limiting portion 143, which is used to limit the supporting arm 142. The limiting portion 143 is connected to the protective plate 1412 and is spaced apart from the bottom plate 1411. The limiting portion 143 is located on the side of the supporting arm 142 away from the bottom plate 1411 to limit the distance between the supporting arm 142 and the bottom plate 1411. As a specific example, in the present embodiment, the limiting portion 143 is a plate-like structure. In other embodiments, the limiting portion 143 can also be a block structure, a rod-like structure, or other structures of any other form, without limitation. Through the above arrangement, since the limiting portion 143 is arranged on the side of the supporting arm 142 away from the bottom plate 1411, the limiting portion 143 can prevent the supporting arm 142 from being too far away from the bottom plate 1411. Therefore, when the circuit board 12 equipped with the conductive spring sheet 14 is installed and inserted into the first inner cavity 103, it is only necessary to compress the supporting arm 142 a short distance in the direction close to the bottom plate 1411, so it is convenient for production staff to install the circuit board 12 equipped with the conductive spring sheet 14 into the first inner cavity 103.
[0047] In some embodiments, the supporting arm 142 includes an extension portion 1421 and a bent portion 1422. The extension portion 1421 is connected between the bottom plate 1411 and the bent portion 1422 and is located at the bent portion 1422 near the second end 102 (see Figure 3 ) side; at least part of the structure of the extension portion 1421 is parallel to the circuit board 12, the bending portion 1422 is bent relative to the extension portion 1421 and extends toward the inner wall of the first housing 10, the limiting portion 143 is located on the side of the extension portion 1421 away from the circuit board 12, and is located on the extension portion 1421 toward the second end 102 (reference Figure 3 ). Through the above arrangement, when the circuit board 12 with the conductive spring 14 installed is installed and inserted into the first inner cavity 103, the bending portion 1422 will encounter friction resistance when in contact with the inner wall of the first inner cavity 103. Since the circuit board 12 moves toward the direction close to the first end 101, the bending portion 1422 will encounter friction resistance in the direction toward the second end 102. Since the limiting portion 143 is arranged on the side of the bending portion 1422 close to the second end 102, the limiting portion 143 can prevent the bending portion 1422 from being displaced and deformed in the direction close to the second end 102, so that the bending portion 1422 can always be in contact with the inner wall of the first shell 10, thereby ensuring the electrical connection stability of the conductive spring 14.
[0048] See also Figure 5In some embodiments, the antenna 13 includes a first conductive member 131 and a second conductive member 132, both of which are metal conductors, which are used to constitute the radiator part of the antenna 13. The first conductive member 131 is roughly in the shape of a long strip, one end of the first conductive member 131 is electrically connected to the second electrode contact, and the other end is connected to the second conductive member 132. The second conductive member 132 is arranged in the second inner cavity 111, and at least part of the structure of the second conductive member 132 is exposed to the second shell 11 through the second inner cavity 111 to be electrically connected to the second electrode of the charging power supply. Through the above arrangement, when the temperature detection device 100 needs to be charged, the second conductive member 132 can be used as a charging electrode, and the second conductive member 132 is electrically connected to the second electrode of the charging power supply, so that the second electrode and the circuit board 12 can be connected.
[0049] Please also see Figure 5 and Figure 6 In some embodiments, the second end 102 of the first shell 10 is accommodated in the second inner cavity 111. The temperature detection device 100 also includes an insulating spacer 15, which is made of an insulating material, such as plastic, ceramic, etc. At least part of the structure of the insulating spacer 15 is disposed in the second inner cavity 111 and is located between the first shell 10 and the second conductive member 132 to separate the first shell 10 from the second conductive member 132. Through the above arrangement, the insulating spacer 15 hinders the contact between the first shell 10 and the second conductive member 132, so when the temperature detection device 100 is charged, the first shell 10 and the second conductive member 132, which are respectively used as two charging electrodes, will not directly contact and short-circuit, so the charging safety of the temperature detection device 100 can be improved.
[0050] In some embodiments, the insulating spacer 15 is provided with a clearance channel 151, which passes through both ends of the insulating spacer 15 and connects the first inner cavity 103 with the second inner cavity 111, and the first conductive member 131 is inserted into the clearance channel 151. In this embodiment, the hole axis direction of the clearance channel 151 is substantially the same as the length direction X of the first shell 10, and the first conductive member 131 passes through the insulating spacer 15 along the hole axis direction of the clearance channel 151. Through the above arrangement, the clearance channel 151 provides space for the arrangement of the first conductive member 131, which can play an insulating role without affecting the installation arrangement of the first conductive member 131.
[0051] In some embodiments, the temperature detection device 100 further includes a second temperature sensing probe and a second wire (neither of which is shown in the figure). The second temperature sensing probe is disposed in the second inner cavity 111, and the second temperature sensing probe is electrically connected to the circuit board 12 through the second wire, and the second wire is passed through the clearance channel 151. Through the above arrangement, the second temperature sensing probe is disposed at one end of the temperature detection device 100 away from the temperature measuring end (i.e., the temperature measuring part 105), which is used to detect the ambient temperature, and the second wire connected thereto can pass through the clearance channel 151 and be electrically connected to the circuit board 12, which facilitates the wiring.
[0052] See also Figure 7 In some embodiments, a clearance groove 1312 is provided on the first conductive member 131, and at least part of the structure of the second conductive member is located in the clearance groove 1312. As a specific example, in the present embodiment, the clearance groove 1312 is a groove structure formed by bending the depression / protrusion of the structure of the first conductive member 131 itself. In other embodiments, the clearance groove 1312 can also be a groove structure directly opened on the surface of the first conductive member 131. Through the above arrangement, the clearance groove 1312 is used to provide an escape space for the routing of the second conductive member to facilitate the routing of the second conductive member. At the same time, the second conductive member is located in the clearance groove 1312 and contacts the clearance groove 1312. The clearance groove 1312 can also play a certain positioning effect on the second conductive member, thereby improving the stability of the second conductive member.
[0053] In some embodiments, the first conductive member 131 extends along the length direction X of the first housing 10, and a reinforcing rib 1311 is provided on the first conductive member 131, and the reinforcing rib 1311 extends along the length direction X of the first housing 10. As a specific example, in this embodiment, the reinforcing rib 1311 is a convex rib structure formed by the bending protrusion of the first conductive member 131 itself. In other embodiments, the reinforcing rib 1311 can also be a convex rib structure directly provided on the surface of the first conductive member 131. Through the above arrangement, the reinforcing rib 1311 can strengthen the self-structural strength of the first conductive member 131 to prevent the first conductive member 131 from bending and deforming during the installation process. In addition, since the reinforcing rib 1311 is formed by the bending protrusion of the first conductive member 131 itself in this embodiment, a clearance groove 1312 can also be formed while forming the reinforcing rib 1311 to facilitate the routing of the second wire, killing two birds with one stone.
[0054] Please refer again Figure 5 and Figure 6In some embodiments, the second inner cavity 111 includes a first hole section 1111, and the first hole section 1111 is at least a partial structure of the second inner cavity 111. The first shell 10 is provided in the first hole section 1111, and at least a part of the inner wall of the first hole section 1111 is spaced from the outer wall of the first shell 10, and a colloid is filled between at least a part of the inner wall of the first hole section 1111 and the outer wall of the first shell 10. As a specific example, in this embodiment, a part of the inner wall of the first hole section 1111 at one end close to the circuit board 12 is in contact with the outer wall of the first shell 10, and a part of the inner wall of the first hole section 1111 at one end away from the circuit board 12 is separated from the outer wall of the first shell 10, and a colloid is filled between the two. In other embodiments, the inner wall of the first hole section 1111 at one end close to the circuit board 12 may be separated from the outer wall of the first shell 10, and a colloid (not shown in the figure) may be filled between the two, and the inner wall of the first hole section 1111 at one end away from the circuit board 12 may be attached to the outer wall of the first shell 10; or the inner wall of the middle part of the first hole section 1111 may be attached / separated from the outer wall of the first shell 10, and the inner wall of the remaining part may be separated / attached to the outer wall of the first shell 10, and this is not limited. With the above arrangement, the second end 102 of the first shell 10 is inserted into the first hole section 1111, and the colloid is bonded to at least part of the structure of the first hole section 1111, so that the first shell 10 and the second shell 11 can be fixedly connected.
[0055] In some embodiments, the second inner cavity 111 further includes a second hole segment 1112 connected to the first hole segment 1111, and the first hole segment 1111 and the second hole segment 1112 are arranged approximately coaxially. The second hole segment 1112 is located at an end of the first hole segment 1111 away from the first end 101, and the aperture of the second hole segment 1112 is larger than the aperture of the first hole segment 1111 to form a first step surface 1113 therebetween. The insulating isolation member 15 includes an isolation portion 152, which is located in the second hole segment 1112 and is arranged opposite to the first step surface 1113, and the second conductive member 132 holds the isolation portion 152 against the second end 102 or the first step surface 1113. As a specific example, in this embodiment, a convex edge 108 is provided on the outer periphery of the second end 102 of the first housing 10, and the convex edge 108 abuts against the first step surface 1113. The isolation portion 152 is located on the side of the convex edge 108 away from the first step surface 1113, and is pressed against the convex edge 108 (i.e., the first housing 10) by the second conductive member 132. Through the above arrangement, the convex edge 108 can limit the first housing 10 from moving out of the first hole section 1111 in a direction away from the second hole section 1112, so as to improve the stability of the connection between the first housing 10 and the second housing 11, and the convex edge 108 and the second conductive member 132 jointly clamp the isolation portion 152, so as to improve the stability of the installation of the insulating isolation member 15. In other embodiments, the first shell 10 may not be provided with the flange 108, and the second end 102 of the first shell 10 may be located in the first hole section 1111, in which case the isolation portion 152 is held against the first step surface 1113 by the second conductive member 132, and the first step surface 1113 and the second conductive member 132 jointly clamp the isolation portion 152 to fix the insulating isolation member 15; alternatively, the second end 102 of the first shell 10 extends into the second hole section 1112, in which case the isolation portion 152 is held against the second end 102 of the first shell 10 by the second conductive member 132, and the first shell 10 and the second conductive member 132 jointly clamp the isolation portion 152 to fix the insulating isolation member 15. In some embodiments, the isolation portion 152 is spaced apart from the inner wall of the second hole segment 1112 and the first step surface 1113, and the portion of the inner wall of the first hole segment 1111 spaced apart from the first shell body 10 is connected to the second hole segment 1112. At this time, glue is injected into the second hole segment 1112, and the glue can pass through the gap between the isolation portion 152 and the second hole segment 1112, the gap between the isolation portion 152 and the first step surface 1113, and then enter the gap between the first hole segment 1111 and the first shell body 10, thereby achieving a fixed connection between the first shell body 10 and the inner wall of the first hole segment 1111, and the operation is simple and convenient.
[0056] In some embodiments, the insulating spacer 15 further includes an extension portion 153, which is generally in the shape of a long strip. The extension portion 153 is connected to the side of the isolation portion 152 close to the first shell 10, and the extension portion 153 is inserted into the first inner cavity 103 and fits with the inner wall of the first inner cavity 103. The extension portion 153 extends along the first shell 10 toward the direction close to the circuit board 12. Through the above arrangement, since the extension portion 153 fits with the inner wall of the first shell 10, the first shell 10 can limit the extension portion 153, thereby improving the stability of the installation of the insulating spacer 15.
[0057] In some other embodiments, the second inner cavity 111 includes a first hole portion 1114 and a second hole portion 1115 connected in series, the first hole portion 1114 is located at an end of the second hole portion 1115 away from the first housing 10, at least part of the structure of the insulating spacer 15 is disposed in the second hole portion 1115, the aperture of the first hole portion 1114 is larger than the aperture of the second hole portion 1115 to form a second step surface 1116 therebetween, and at least part of the structure of the second conductive member 132 is located in the first hole portion 1114 and is disposed opposite to the second step surface 1116. As a specific example, in this embodiment, the part of the structure of the second conductive member 132 located in the first hole portion 1114 is in contact with the second step surface 1116 to limit the second conductive member 132 and prevent the second conductive member 132 from further moving into the second hole portion 1115, so as to ensure that the part of the second conductive member 132 located in the first hole portion 1114 can be stably electrically connected to the charging power source. In other embodiments, the partial structure of the second conductive member 132 located in the first hole portion 1114 may also be spaced apart from the second step surface 1116 .
[0058] In some other embodiments, the second end 102 of the first shell 10 is accommodated in the second hole 1115. The second conductive member 132 includes a power connection portion 1321 and a support portion 1322 connected to each other. The power connection portion 1321 is a portion of the second conductive member 132 used to contact the second electrode of the charging power source to achieve electrical connection between the two, and the support portion 1322 is a portion of the second conductive member 132 that contacts the insulating isolation member 15. The power connection portion 1321 is disposed in the first hole 1114 and is disposed opposite to the second step surface 1116. The power connection portion 1321 is exposed through the first hole 1114 so as to contact the second electrode of the charging power source. The support portion 1322 is located in the second hole 1115, and one end of the support portion 1322 away from the power connection portion 1321 contacts the insulating isolation member 15, and presses the insulating isolation member 15 against the second end 102 of the first shell 10. As a specific example, in the present embodiment, the abutting portion 1322 is a long strip structure, the power connection portion 1321 is a roughly cylindrical structure, the power connection portion 1321 is embedded in the first hole portion 1114, the abutting portion 1322 is arranged in the second hole portion 1115, and one end of the abutting portion 1322 is connected to the power connection portion 1321, and the other end abuts against the isolation portion 152 of the insulating isolation member 15. In other embodiments, the power connection portion 1321 can also be a cubic structure or an irregular structure or other structures, and the abutting portion 1322 can also be a block structure or a cylindrical structure or other structures, and the specific forms of the power connection portion 1321 and the abutting portion 1322 are not limited. Through the above arrangement, the second conductive member 132 can be electrically connected to the second electrode of the charging power supply to be used as a charging electrode of the temperature detection device 100, and can also abut and press the insulating isolation member 15 against the first shell 10, thereby improving the stability of the installation of the insulating isolation member 15.
[0059] Please also see Figure 8 and Fig. 9In some embodiments, the power connection portion 1321 is provided with a glue injection hole 1323 and an exhaust hole 1324, and the glue injection hole 1323 and the exhaust hole 1324 both connect the first hole portion 1114 with the second hole portion 1115, and the second hole portion 1115 is filled with a thermal conductive glue (not shown in the figure). Through the above arrangement, after the production worker installs the second conductive member 132 into the second shell 11, the production worker can inject thermal conductive glue into the second hole 1115 through the glue injection hole 1323. After the thermal conductive glue fills the second hole 1115, it will completely wrap the second temperature sensing probe (not shown in the figure). At the same time, the thermal conductive glue will contact the second conductive member 132 and the inner wall of the second shell 11. After the thermal conductive glue solidifies, a thermal conductive colloid can be formed to fix the second temperature sensing probe and the second conductive member 132. Due to the presence of the thermal conductive colloid, the rate at which the external heat is transmitted to the second temperature sensing probe after passing through the second shell 11 can be accelerated, and the accuracy of the detection result of the second temperature sensing probe on the ambient temperature can be improved. In addition, the thermal conductive colloid can also play a role in sealing and waterproofing, which is used to prevent external water vapor from entering the second hole 1115 to ensure that the temperature detection device 100 can work normally. During the above-mentioned glue injection process, the gas in the second hole 1115 can be discharged through the exhaust hole 1324 to facilitate smooth glue injection.
[0060] In other embodiments, the glue injection hole 1323 and the exhaust hole 1324 can also be opened on the outer wall of the power connection part 1321, and one end of the glue injection hole 1323 and the exhaust hole 1324 is opened on the outer wall of the power connection part 1321, and the other end is opened on the surface of the power connection part 1321 facing the supporting part 1322. Through the above arrangement, the first hole part 1114 and the second hole part 1115 can also be connected, and the glue injection hole 1323 and the exhaust hole 1324 are respectively used to inject thermal conductive glue and exhaust excess air.
[0061] In some embodiments, a receiving groove 1325 is provided on the side of the power connection part 1321 away from the supporting part 1322, and the glue injection hole 1323 and the exhaust hole 1324 are arranged on the bottom wall of the receiving groove 1325. The antenna 13 also includes a third conductive member 133, which is located in the receiving groove 1325 and electrically connected to the power connection part 1321, and covers the glue injection hole 1323 and the exhaust hole 1324. As a specific example, in this embodiment, the inner wall of the receiving groove 1325 is provided with an internal thread, the outer wall of the third conductive member 133 is provided with an external thread adapted to the internal thread, and the third conductive member 133 is threadedly connected to the second conductive member 132. In other embodiments, the third conductive member 133 and the second conductive member 132 can also be connected by the matching snap-fit connection of the buckle and the slot, or by other connection methods, which is not limited. Through the above arrangement, the third conductive member 133 can increase the area of the antenna 13 exposed to the second shell 11, thereby enhancing the communication signal of the antenna 13 and improving the communication quality.
[0062] In some embodiments, the second conductive member 132 is provided with a plug-in slot 1326, and one end of the first conductive member 131 away from the circuit board 12 is inserted into the plug-in slot 1326. The plug-in slot 1326 can be specifically provided on the surface of the power connection portion 1321 facing the abutting portion 1322, and one end of the first conductive member 131 away from the circuit board 12 is inserted into the plug-in slot 1326 and is welded and fixed to the second conductive member 132. Through the above arrangement, the stability of the connection between the first conductive member 131 and the second conductive member 132 can be improved, thereby ensuring the communication quality of the antenna 13 and the stable conduction of the charging circuit of the temperature detection device 100.
[0063] In addition, in this embodiment, since the first conductive member 131 can be separately manufactured by stamping, and the second conductive member 132 and the third conductive member 133 can be separately manufactured by machining, the multiple components of the antenna 13 can be separately manufactured and processed, and then connected and assembled, thereby reducing the processing difficulty and production cost of the antenna 13.
[0064] See also Figure 6 In some embodiments, the temperature detection device 100 further includes a sealing ring 16, which is sleeved on the outer periphery of the power connection portion 1321, and the sealing ring 16 is clamped by the power connection portion 1321 and the inner wall of the first hole portion 1114. In the present embodiment, one sealing ring 16 is provided, and in other embodiments, multiple sealing rings 16 may be provided. Through the above arrangement, the inner wall of the first hole portion 1114 and the power connection portion 1321 clamp the sealing ring 16 together to form a sealing structure, which can prevent other impurities such as external liquid from entering the second shell 11 from the gap between the power connection portion 1321 and the first hole portion 1114, thereby ensuring that the temperature detection device 100 can work normally.
[0065] In summary, the embodiment of the present application provides a temperature detection device 100, which uses its first housing 10 and antenna 13 as two charging electrodes respectively, which can save the need for separate arrangement of the charging electrodes, thereby simplifying its structure and reducing its volume. In addition, since at least part of the structure of the antenna 13 is exposed to the outside world, it can also effectively enhance the signal strength of the antenna 13 and improve the communication quality.

The first shell 10 of the temperature detection device 100 is used to be electrically connected to the first electrode 211, and the antenna 13 of the temperature detection device 100 is used to be electrically connected to the second electrode 212. Through the above configuration, when the first shell 10 of the temperature detection device 100 is electrically connected to the first electrode 211 and the antenna 13 is electrically connected to the second electrode 212 , a closed charging loop can be formed between the power supply and the circuit board 12 to charge the temperature detection device 100 .

When the temperature detection device 100 is placed in the storage slot 22, the first shell 10 will be clamped by the two conductive sheets, thereby achieving electrical connection with the first electrode 211. Through the above arrangement, the first electrode 211 is not only used to conduct with the first shell 10, but also can clamp the first shell 10, playing the role of fixing the temperature detection device 100.
