[0002] A food thermometer is a temperature measuring device for measuring the internal temperature of food or other objects, which has high precision, fast response and other characteristics. A common food thermometer includes a probe and a handle connected together, and the inside of the probe is provided with an electrically connected circuit board and a battery. The user can use a charging device (such as a charging box, a charging base, etc.) that matches the model to charge the battery inside the food thermometer, so that the food thermometer can be used in a wireless state.

[0003] At present, in order to charge the battery, the shell of the probe is usually used as a charging electrode.

[0031] Please refer to Figure 1Embodiments of the present application provide a temperature detection device 100 for contacting 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 (e.g. a roast meat temperature probe, a hot pot temperature probe, etc.), or a household / industrial thermometer. The specific type and use scenario of the temperature detection device 100 are not limited.

[0032] Please refer to 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 a conductive part 13.

[0033] The first housing 10 is a main body part 1121 of the temperature detection device 100, and is generally in the shape of an elongated round rod. One end (i.e. the first end 102 below) of the first housing 10 is generally in the shape of a cone, so that it can be more easily inserted into the interior of food or an article to obtain the internal temperature. The first housing 10 is provided with a first inner cavity 101, and has a first end 102 and a second end 103 opposite to each other, and the first end 102 is adapted to contact with the object to be measured.

[0034] The second housing 11 is used for a user to hold to use the temperature detection device 100. The second housing 11 includes a conductive shell 111 and an insulating shell 112 connected to each other, and the conductive shell 111 is connected to the first housing 10 and located at the second end 103. It should be noted that the conductive shell 111 itself has the ability to conduct electricity, and the insulating shell 112 itself does not have the ability to conduct electricity. As a specific example, in the present embodiment, the conductive shell 111 is a stainless steel shell, and the insulating shell 112 is a ceramic shell. In other embodiments, the conductive shell 111 can also be a copper shell, an aluminum shell, or any other shell made of a conductor material, and the insulating shell 112 can also be a plastic shell, a resin shell, or any other shell made of an insulator material.

[0035] The circuit board 12 is arranged in the first inner cavity 101, and 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 conductive shell 111, and the conductive shell 111 is used to be electrically connected to one electrode of a charging power supply to receive electrical energy. That is, the conductive shell 111 serves as one electrode when the temperature detection device 100 is charged. The charging power supply is an external power supply, and the conductive shell 111 is used to connect the positive electrode or the negative electrode of the charging power supply.

[0036] The conductive part 13 is arranged on the insulating shell 112 and separated from the conductive shell 111, and the conductive part 13 is electrically connected with the second electrode contact, and the conductive part 13 is used to be electrically connected with another electrode of the charging power supply to receive electric energy. That is, the conductive part 13 is used as another electrode of the temperature detection device 100 when charging. It should be noted that "the conductive part 13 is separated from the conductive shell 111" means that the conductive part 13 and the conductive shell 111 are not in contact with each other, and they are arranged separately from each other to avoid the conductive part 13 and the conductive shell 111 as two electrodes to be in contact with each other to cause short circuit of the charging circuit during charging of the temperature detection device 100. As a specific example, in the embodiment, the conductive part 13 is made of stainless steel material, and in other embodiments, the conductive part 13 can also be made of any conductor material such as metal copper, metal aluminum, etc.

[0037] Through the above arrangement, since the second shell 11 includes the connected conductive shell 111 and the insulating shell 112, the conductive shell 111 is electrically connected with the first electrode contact of the circuit board 12, the conductive shell 111 is used to be electrically connected with one electrode of the charging power supply to receive electric energy, the conductive part 13 is arranged on the insulating shell 112 and separated from the conductive shell 111, and the conductive part 13 is electrically connected with the second electrode contact of the circuit board 12, and the conductive part 13 is used to be electrically connected with another electrode of the charging power supply to receive electric energy, so the conductive shell 111 and the conductive part 13 can be used as two charging electrodes of the temperature detection device 100 electrically connected with the charging device, since the conductive shell 111 is a component of the second shell 11, and the conductive part 13 is arranged on the insulating shell 112 of the second shell 11, so both charging electrodes of the temperature detection device 100 are arranged on the second shell 11, so the charging device used in cooperation with the above temperature detection device 100 can arrange two power supply electrodes in the accommodating groove 201 used to accommodate the second shell 11, without the need to arrange other structures at the position corresponding to the first shell 10. In summary, the above temperature detection device 100 can simplify the structure of the charging device used in cooperation therewith, reduce the size of the charging device, and save the production cost of the charging device.

[0038] Please continue to refer to Figure 1 , Figure 2 and Figure 3In some embodiments, the second housing 11 is provided with a second inner cavity 113 which is in communication with the first inner cavity 101. The second inner cavity 113 can be a cavity which is jointly defined by the conductive shell 111, the insulating shell 112 and the conductive member 13. The insulating shell 112 is provided with an electrical connection port 114 which is in communication with the second inner cavity 113. The conductive shell 111 is connected to one end of the insulating shell 112, and the electrical connection port 114 is located on the end face of the end of the insulating shell 112 which is away from the conductive shell 111. The conductive member 13 is arranged in the second inner cavity 113, and at least part of the structure of the conductive member 13 is exposed to the insulating shell 112 via the electrical connection port 114, so that the conductive member 13 and the conductive shell 111 are respectively located at two ends of the insulating shell 112. It should be noted that "at least part of the structure of the conductive member 13 is exposed to the insulating shell 112 via the electrical connection port 114" at least includes the following cases: the conductive member 13 is completely located inside the second inner cavity 113; at least part of the structure of the conductive member 13 extends to outside the second inner cavity 113 through the electrical connection port 114; and at least part of the structure of the conductive member 13 is flush with the electrical connection port 114. Through the above arrangement, since the conductive shell 111 and the conductive member 13 which are the charging electrodes are respectively located at two ends of the insulating shell 112, it can be ensured that the conductive shell 111 and the conductive member 13 are as far away from each other as possible to avoid short circuit caused by accidental contact therebetween. Moreover, when the user needs to charge the temperature detection device 100, the conductive member 13 can be electrically connected to one electrode of the charging power supply at the electrical connection port 114, and the operation is simple and convenient.

[0039] In some embodiments, the second inner cavity 113 includes an internally threaded segment 1131. It should be noted that "the second inner cavity 113 includes an internally threaded segment 1131" means that the internally threaded segment 1131 is a part of the structure of the second inner cavity 113, which is generally a part of the hole segment, and the inner side wall of the internally threaded segment 1131 is provided with internal threads. The conductive member 13 includes a connecting portion 131 and an electrical connection portion 132 which are connected to each other. The connecting portion 131 is a part of the conductive member 13 which is used to realize connection with the insulating shell 112, and the connecting portion 131 is inserted into the second inner cavity 113 and is screwed with the internally threaded segment 1131. In order to facilitate screwing, the connecting portion 131 is generally cylindrical. The electrical connection portion 132 is a part of the conductive member 13 which is used to directly contact with the electrode of the charging power supply to realize electrical connection, and the electrical connection portion 132 is exposed to the insulating shell 112 via the electrical connection port 114. In order to increase the electrical connection area, the electrical connection portion 132 is generally in the shape of a circular cake, and the diameter of the electrical connection portion 132 is greater than the diameter of the connecting portion 131.

[0040] Through the above arrangement, when the staff installs and connects the conductive part 13 with the insulating shell 112, only need to screw the connecting part 131 of the conductive part 13 into the inside of the insulating shell 112, so as to realize the screw thread connection between the connecting part 131 and the internal thread segment 1131, the operation is simple and convenient. Moreover, the electricity connection part 132 is exposed to the insulating shell 112 through the electricity connection port 114, and the diameter of the electricity connection part 132 is larger than the diameter of the connecting part 131, so that the electricity connection area of the conductive part 13 can be increased, which is beneficial to the stable contact between the conductive part 13 and the electrode of the charging power supply, so as to improve the stability and reliability of the temperature detection device 100 when charging.

[0041] Please refer to Figure 2 and Figure 3 In some embodiments, the connecting part 131 is provided with a screw thread connection hole 133 towards the end surface of the circuit board 12. The screw thread connection hole 133 is a circular hole structure, and at least part of the inner side wall of the screw thread connection hole 133 is provided with an internal thread, and the screw thread direction and the pitch of the internal thread are the same as those of the internal thread segment 1131. The temperature detection device 100 further comprises a conductive connecting part 14, which is made of a conductor material, such as stainless steel, copper, aluminum, etc. The conductive connecting part 14 is substantially in a strip shape, one end of the conductive connecting part 14 is electrically connected with the second electrode contact, for example, one end of the conductive connecting part 14 can be directly or indirectly welded on the second electrode contact. The other end of the conductive connecting part 14 is engaged with the screw thread connection hole 133, that is, the outer side wall of the end of the conductive connecting part 14 away from the circuit board 12 is provided with an external thread matched with the internal thread in the screw thread connection hole 133.

[0042] Through the above arrangement, the conductive connecting part 14 is used to realize the electrical connection between the second electrode contact and the conductive part 13, so that the conductive part 13 can be used as a charging electrode of the temperature detection device 100. Moreover, since the inner side wall of the screw thread connection hole 133 is provided with an internal thread having the same screw thread direction and pitch as those of the internal thread segment 1131, and the outer side wall of the end of the conductive connecting part 14 away from the circuit board 12 is provided with an external thread matched with the internal thread in the screw thread connection hole 133, when the staff screws the connecting part 131 of the conductive part 13 into the internal thread segment 1131, the end of the conductive connecting part 14 away from the circuit board 12 can be screwed into the screw thread connection hole 133, so as to realize the electrical connection between the conductive connecting part 14 and the conductive part 13. In summary, when the staff connects the conductive part 13 with the insulating shell 112, the electrical connection between the conductive connecting part 14 and the conductive part 13 can also be realized, so that the operation steps of the staff in assembling the temperature detection device 100 can be simplified, and the assembly efficiency is improved. Moreover, the screw thread connection between the conductive connecting part 14 and the conductive part 13 can also improve the stability of the connection, so as to ensure the stable electrical connection between them.

[0043] Please continue to refer to Figure 2 andFigure 3 In some embodiments, the conductive connector 14 is provided with a receiving through hole 141. The temperature detection device 100 further comprises a first temperature sensor 15 and a first lead wire 16. The first temperature sensor 15 is arranged in the threaded hole 133, and the first lead wire 16 is electrically connected between the first temperature sensor 15 and the circuit board 12, and the first lead wire 16 is arranged through the receiving through hole 141. Through the above arrangement, the first temperature sensor 15 is located at one end of the temperature detection device 100 away from the temperature measurement site (i.e. the first end 102 of the first shell 10), which is used to detect the ambient temperature, and the first lead wire 16 connected thereto is arranged through the receiving through hole 141 of the conductive connector 14 and electrically connected with the circuit board 12, which can have the effects of facilitating wiring, saving space, and reducing the volume of the second shell 11.

[0044] In some embodiments, the temperature detection device 100 further comprises a conductive spring 17. The conductive spring 17 is arranged on the circuit board 12 and elastically abuts against the inner wall of the conductive shell 111, and the conductive spring 17 is electrically connected with the first electrode contact, for example, the conductive spring 17 can be directly or indirectly welded on the first electrode contact. It should be noted that "the conductive spring 17 elastically abuts against the inner wall of the conductive shell 111" means that the part of the structure where the conductive spring 17 abuts against the inner wall of the conductive shell 111 can elastically deform, or the part of the structure where the conductive spring 17 abuts against the inner wall of the conductive shell 111 has a tendency to move towards the inner wall of the conductive shell 111 under the action of other elastic members. For example, the part of the structure where the conductive spring 17 abuts against the inner wall of the conductive shell 111 can be a thin piece of metal with elasticity, or the part of the structure where the conductive spring 17 abuts against the inner wall of the conductive shell 111 can stably contact the inner wall of the conductive shell 111 under the action of the elastic force of a spring. Through the above arrangement, the conductive spring 17 can realize the electrical connection between the conductive shell 111 and the first electrode contact, so that the conductive shell 111 can be used as a charging electrode of the temperature detection device 100.

[0045] In some embodiments, the number of the conductive spring 17 is multiple, and the multiple conductive springs 17 are arranged on the opposite sides of the circuit board 12. As a specific example, in the present embodiment, the conductive spring 17 is provided with two, and the two conductive springs 17 are respectively located on the opposite sides of the circuit board 12. In other embodiments, the number of the conductive spring 17 can also be three, four, five, etc. Through the above arrangement, since the conductive spring 17 is provided with multiple, when a certain conductive spring 17 is in poor contact with the conductive shell 111, other conductive springs 17 can also ensure the stable conduction of the circuit board 12 and the conductive shell 111, so as to improve the stability of charging. In addition, the conductive springs 17 located on the two sides of the circuit board 12 are respectively abutted on the inner wall of the conductive shell 111, which can not only play a conductive role, but also support and fix the circuit board 12, so that the fixing structure of the circuit board 12 can be unnecessary, thereby simplifying the structure and reducing the size.

[0046] In some embodiments, the insulating shell 112 includes a main body part 1121 and a threaded connection part 1122 connected with each other, and the main body part 1121 and the threaded connection part 1122 are both substantially cylindrical and coaxially arranged. The threaded connection part 1122 is arranged at one end of the main body part 1121, and the conductive shell 111 is threadedly nested and connected with the threaded connection part 1122. It should be noted that the "threadedly nested and connected of the conductive shell 111 with the threaded connection part 1122" at least includes the following two cases: at least part of the structure of the conductive shell 111 is sleeved outside the threaded connection part 1122 and is threadedly connected with the threaded connection part 1122; at least part of the structure of the conductive shell 111 is inserted into the inside of the threaded connection part 1122 and is threadedly connected with the threaded connection part 1122. Through the above arrangement, the threaded connection of the conductive shell 111 with the insulating shell 112 is realized, which can facilitate the connection and assembly of the conductive shell 111 with the insulating shell 112 by the staff.

[0047] Please refer to Figure 2 In some embodiments, the temperature detection device 100 further includes a second temperature sensor 18 and a second lead wire 19. The second temperature sensor 18 is arranged in the first inner cavity 101 and located at the first end 102, and the second lead wire 19 is electrically connected between the second temperature sensor 18 and the circuit board 12. Through the above arrangement, when the user uses the temperature detection device 100, the first end 102 of the first shell 10 is in contact with the object to be measured, and the second temperature sensor 18 located at the first end 102 can quickly obtain the temperature of the object to be measured, so as to realize the function of rapid temperature measurement.

[0048] Please refer to Figure 4 , Figure 5 and Figure 6The embodiment of the present application also provides a charging device 200 for charging the temperature detection device 100. The charging device 200 comprises a charging base 20, a first electrode 22, a second electrode 23 and a power supply 24.

[0049] The charging base 20 is used for storing the temperature detection device 100 and charging the temperature detection device 100. The charging base 20 is provided with a receiving groove 201 for receiving the second shell 11 of the temperature detection device 100. The receiving groove 201 extends to one side of the charging base 20 and communicates with the outside of the charging base 20, so that the first shell 10 of the temperature detection device 100 extends from the position to the outside of the receiving groove 201. The first electrode 22 is arranged in the receiving groove 201 and is used for electrically connecting with the conductive shell 111 of the temperature detection device 100. The second electrode 23 is arranged in the receiving groove 201 and is used for electrically connecting with the conductive member 13 of the temperature detection device 100. The first electrode 22 and the second electrode 23 can be conductors in any shape such as a sheet, a patch or a jaw, and the first electrode 22 and the second electrode 23 can have the same or different structures. The power supply 24 is used as a charging power supply for the temperature detection device 100. The power supply 24 is arranged in the charging base 20. The positive electrode of the power supply 24 is electrically connected with one of the first electrode 22 and the second electrode 23, and the negative electrode of the power supply 24 is electrically connected with the other of the first electrode 22 and the second electrode 23.

[0050] Through the above arrangement, when the second shell 11 of the temperature detection device 100 is placed in the receiving groove 201, the conductive shell 111 is electrically connected with the first electrode 22 and the conductive member 13 is electrically connected with the second electrode 23, so that a closed charging loop is formed between the power supply 24 and the circuit board 12 to charge the temperature detection device 100. Since the charging base 20 of the charging device 200 is only provided with the receiving groove 201 for receiving the second shell 11 and does not need to be provided with other structures or components for electrically connecting with the first shell 10, the volume of the charging base 20 can be reduced, thereby reducing the overall volume of the charging device 200 and saving material cost.

[0051] In some embodiments, the charging device 200 further comprises a cover 21 connected with the charging base 20 and covering the receiving groove 201. The cover 21 can be detached from the charging base 20 to completely expose the receiving groove 201. The cover 21 can also be rotationally connected with the charging base 20 and can be rotated relative to the charging base 20 to completely expose the receiving groove 201. Through the above arrangement, when the charging device 200 charges the temperature detection device 100, the cover 21 can protect the second shell 11 to stabilize the charging operation.

[0052] Please refer to Figure 6 andFigure 7 The embodiment of the present application also provides a temperature detection device 300, which comprises the temperature detection apparatus 100 and the charging apparatus 200, and the second shell 11 of the temperature detection apparatus 100 is embedded in the accommodating groove 201 of the charging apparatus 200. Through the above arrangement, when the second shell 11 of the temperature detection apparatus 100 is removed from the accommodating groove 201 of the charging apparatus 200, the user can use the temperature detection apparatus 100 to detect the temperature of an object, and when the second shell 11 of the temperature detection apparatus 100 is placed in the accommodating groove 201 of the charging apparatus 200, the charging apparatus 200 can charge the temperature detection apparatus 100, so that the user can use the temperature detection apparatus 100 next time.
