[0036] ​In addition, the features described in the specification, operations or characteristics can be combined in any appropriate manner to form various embodiments. Meanwhile, the steps or actions in the method description can also be sequentially changed or adjusted in a manner that can be apparent to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the sequence is necessary, unless otherwise stated that a certain sequence must be followed.

[0037] The serial numbers of the components in the specification, such as "first", "second", etc., are only used to distinguish the described objects, and do not have any order or technical meaning. The "connection" and "coupling" in the present application include direct and indirect connections (couplings) unless otherwise specified.

[0038] The embodiment provides a temperature detection device.

[0039] Please refer to Figures 1-10 The temperature detection device comprises a shell assembly 100, a circuit board 200, a temperature probe 300, a switch piece 400 and a rotating shaft piece 500.

[0040] Please refer to Figures 1-4 , 9 and 10, the shell assembly 100 is provided with a display screen 110, the circuit board 200 is arranged in the shell assembly 100, and the circuit board 200 is electrically connected with the display screen 110. The temperature probe 300 is used for temperature detection, and the temperature probe 300 has a thermocouple wire 310. The switch piece 400 is electrically connected with the display screen 110, and the switch piece 400 is used for controlling the display screen 110 to start when being triggered. The temperature probe 300 is rotatably connected with the shell assembly 100 through the rotating shaft piece 500, the temperature probe 300 can rotate relative to the shell assembly 100 to realize stretching and folding, and the temperature probe 300 can trigger the switch piece 400 when being rotated to a predetermined included angle with the shell assembly 100. The rotating shaft piece 500 and / or the shell assembly 100 form a mounting cavity 520, the mounting cavity 520 is provided with a partition 550, the partition 550 divides the mounting cavity 520 into a first cavity 521 and a second cavity 522. The thermocouple wire 310 extends to the circuit board 200 through the first cavity 521 and is electrically connected with the circuit board 200, and the switch piece 400 is arranged in the second cavity 522.

[0041] Please refer to Figures 1-49 and 10: When the user needs to use the temperature detection device, the temperature probe 300 can be rotated relative to the housing assembly 100 to extend it, so that the temperature probe 300 can be inserted into the object or environment where the temperature needs to be detected. During the rotation and extension of the temperature probe 300, the switch 400 is triggered, thereby turning on the display screen 110. After being turned on, the display screen 110 is used to display at least the temperature value detected by the temperature probe 300. That is, the user only needs to perform one operation of extending the temperature probe 300 to additionally turn on the display screen 110, thus making the operation of the temperature detection device more convenient. Furthermore, since the thermocouple wire 310 and the switch 400 are located in the mutually isolated first cavity 521 and second cavity 522 respectively, the thermocouple wire 310 and the switch 400 will not interfere with each other when the user rotates the temperature probe 300, which helps to improve the service life of the temperature detection device, especially increasing the total number of times the temperature probe 300 can be rotated, extended, and folded relative to the housing assembly 100 via the pivot 500.

[0042] Moreover, in the scenario of assembling a temperature detection device, the first cavity 521 and the second cavity 522 can guide the assembler to more easily place the thermocouple wire 310 and the switch 400 into the corresponding cavity, thereby improving the assembly efficiency of the assembler.

[0043] Specifically, the mounting cavity 520 can be formed by the joint enclosure of the rotating shaft 500 and the housing assembly 100, or by either the rotating shaft 500 or the housing assembly 100. As long as the mounting cavity 520 is divided into a first cavity 521 and a second cavity 522 by the partition 550, the interference between the thermocouple wire 310 and the switching element 400 can be avoided through spatial isolation.

[0044] It should be noted that the aforementioned "predetermined angle" can be a single angle value or an angle range. For example, it could mean that the switch 400 is triggered when the temperature probe 300 rotates to an angle of 175° with the housing assembly 100, or that the switch 400 remains triggered when the temperature probe 300 rotates to an angle between 170° and 180° with the housing assembly 100. Of course, the specific angles mentioned above are just examples; the value of the "predetermined angle" can also be 90°, 120°, 150°, or other suitable values, and the "predetermined angle" can also be an angle range with these angle values ​​as endpoints.

[0045] Please refer to Figures 1-4In one embodiment, the temperature probe 300 and the pivot 500 are rotatable about a first axis on the housing assembly 100. The pivot 500 includes a pivot sidewall 510 and a partition 550. The pivot sidewall 510 surrounds the first axis to form a mounting cavity 520. The partition 550 is connected to the inner wall of the mounting cavity 520 to form a first cavity 521 and a second cavity 522 on opposite sides of the partition 550.

[0046] A mounting cavity 520 is formed by the sidewall 510 of the rotating shaft surrounding the first axis, and a partition 550 is connected to the inner wall of the mounting cavity 520, thereby dividing the mounting cavity 520 into a first cavity 521 and a second cavity 522 that are isolated from each other. Since the first cavity 521 and the second cavity 522 are located on opposite sides of the partition 550, the thermocouple wire 310 and the switching element 400 will not cross the partition 550 and interfere with each other. For details, please refer to... Figure 2 The first axis can be considered as Figure 2 The temperature probe 300 and the rotating shaft 500 can be fixedly connected by adhesive, screws or other suitable means so that the temperature probe 300 and the rotating shaft 500 can rotate synchronously around the first axis on the housing assembly 100.

[0047] Please refer to Figures 1-4 In one embodiment, the first cavity 521, the partition 550, and the second cavity 522 are arranged sequentially along the first axis.

[0048] The partition 550 physically isolates the thermocouple wire 310 and the switch element 400 in the extension direction of the first axis, thereby preventing interference between the thermocouple wire 310 and the switch element 400 when the rotating shaft 500 rotates around the first axis. In other embodiments, the first cavity 521, the partition 550, and the second cavity 522 may also be arranged sequentially in a direction perpendicular to the first axis.

[0049] Please refer to Figures 1-4 In one embodiment, the housing assembly 100 includes a front housing 120 and a rear housing 130, a display screen 110 is mounted on the front housing 120, and the front housing 120 and the rear housing 130 are disposed opposite to each other, and a pivot 500 is mounted between the front housing 120 and the rear housing 130.

[0050] When using the temperature detection device, the user's line of sight is directed toward the front housing 120 of the housing assembly 100 in order to observe the information displayed on the display screen 110. Since the pivot 500 is installed between the front housing 120 and the rear housing 130, the pivot 500 can be rotatably mounted from opposite sides of the pivot 500 via the front housing 120 and the rear housing 130.

[0051] Please refer to Figures 1-4In one embodiment, the pivot member 500 has a first opening 530 on the side facing the front housing 120, the first opening 530 communicating with the first cavity 521, and the front housing 120 covering the first opening 530. The pivot member 500 has a second opening 540 on the side facing the rear housing 130, the second opening 540 communicating with the second cavity 522, and the rear housing 130 covering the second opening 540.

[0052] On the one hand, during the assembly of the temperature detection device, the first opening 530 connects the first cavity 521 to the external environment, and the second opening 540 connects the second cavity 522 to the external environment. This facilitates the installation of components into the first cavity 521 through the first opening 530, and also facilitates the installation of components into the second cavity 522 through the second opening 540. For example, the thermocouple wire 310 can be easily installed into the first cavity 521 through the first opening 530, and the switch 400 can be installed into the second cavity 522 through the second opening 540. On the other hand, the front shell 120 covers the first opening 530, and the rear shell 130 covers the second opening 540, making the surface of the temperature detection device smoother and helping to protect the components inside the first cavity 521 and the second cavity 522. Specifically, the thermocouple wire 310 in the first cavity 521 passes through the front shell 120 and extends to connect with the circuit board 200, and the circuit of the switch 400 passes through the rear shell 130 and extends to connect with the circuit board 200.

[0053] Please refer to Figures 3-8 In one embodiment, the temperature detection device further includes a trigger 600 disposed within the second cavity 522. One of the trigger 600 and the switch 400 is connected to the rotating shaft 500, and the other is connected to the housing assembly 100, so that when the rotating shaft 500 and the temperature probe 300 rotate relative to the housing assembly 100, they can drive the trigger 600 and the switch 400 to rotate relative to each other. When the temperature probe 300 rotates to form a predetermined angle with the housing assembly 100, the trigger 600 rotates relative to the switch 400 until it contacts the switch 400, thereby triggering the switch 400.

[0054] During the user's rotation of the shaft 500 and temperature probe 300, the trigger 600 and switch 400 rotate relative to each other. When the temperature probe 300 rotates to a predetermined angle with the housing assembly 100, the trigger 600 contacts the switch 400, thereby triggering the switch 400. That is, the switch 400 is triggered by the contact between the trigger 600 and the switch 400. Therefore, the switch 400 can be a pressure-triggered mechanical switch, which helps ensure the reliability of the switch 400. Furthermore, since the trigger 600 and thermocouple 310 are located in different cavities, they do not interfere with each other, allowing the trigger 600 to trigger the switch 400 more smoothly and stably.

[0055] Specifically, the switch 400 can be connected to the housing assembly 100, and the trigger 600 can be connected to the rotating shaft 500. When the user rotates the rotating shaft 500, it causes the trigger 600 to rotate relative to the switch 400, thereby triggering the switch 400. Alternatively, the switch 400 can be connected to the rotating shaft 500, and the trigger 600 can be connected to the housing assembly 100, as long as the rotation of the rotating shaft 500 can cause the switch 400 and the trigger 600 to move relative to each other, thereby triggering the switch 400.

[0056] Please refer to Figures 3-8 In one embodiment, a trigger 600 protrudes from the partition 550 and is arc-shaped around a first axis. The switch 400 has a conductive portion 410 facing the trigger 600. When the temperature probe 300 rotates to form a predetermined angle with the housing assembly 100, the trigger 600 presses the conductive portion 410 to turn on the internal circuitry of the switch 400.

[0057] When the user rotates the temperature probe 300 to a predetermined angle with the housing assembly 100, the trigger member 600 presses the conductive portion 410 of the switch member 400, thereby triggering the switch member 400. Because the trigger member 600 is configured in an arc shape around the first axis, on the one hand, the rotation center line of the trigger member 600 coincides with the rotation center line of the rotating shaft member 500, thus allowing the rotating shaft member 500 to more stably drive the trigger member 600 to rotate. On the other hand, after the arc-shaped trigger member 600 contacts the conductive portion 410 of the switch member 400, as long as the angle of continued rotation of the rotating shaft member 500 is no greater than the central angle of the arc, the arc-shaped trigger member 600 remains in contact with the conductive portion 410, thereby keeping the switch member 400 in a triggered state, and thus keeping the display screen 110 powered on.

[0058] Please refer to Figures 1-3In one embodiment, the temperature detection device further includes a wire positioning member 700, which is disposed in the first cavity 521 and is used to position the thermocouple wire 310 in the first cavity 521.

[0059] At least a portion of the thermocouple wire 310 is fixed within the first cavity 521 by the wire positioning component 700, ensuring that the thermocouple wire 310 is neatly arranged within the first cavity 521. This facilitates wiring and maintenance. For example, the thermocouple wire 310 can be arranged around the inner wall of the first cavity 521 and then extended outside the first cavity 521. Specifically, the wire positioning component 700 can be a snap-fit ​​structure, a strap structure, or other suitable wire positioning structure.

[0060] Please refer to Figures 1-3 In one embodiment, the housing assembly 100 further includes a middle frame housing 140 disposed between the front housing 120 and the rear housing 130, with opposite sides of the middle frame housing 140 correspondingly connected to the front housing 120 and the rear housing 130, respectively. The front housing 120, the rear housing 130, and the middle frame housing 140 each have a first end disposed opposite to each other. The first end of the middle frame housing 140 has a recessed groove 141, within which at least a portion of the pivot member 500 is movably disposed. The first end of the front housing 120 covers a first opening 530, and the first end of the rear housing 130 covers a second opening 540.

[0061] The front shell 120 and the rear shell 130 are connected as a whole by the middle frame shell 140, thereby making the structure of the shell assembly 100 more stable. The recessed groove 141 provides space for mounting the pivot 500 on the middle frame shell 140, thus facilitating the mounting of the pivot 500 on the shell assembly 100. The first end of the front shell 120 covers the first opening 530, and the first end of the rear shell 130 covers the second opening 540, making the surface of the temperature detection device smoother and helping to protect the components inside the first cavity 521 and the second cavity 522.

[0062] Please refer to Figures 1-3 9 and 10, in one embodiment, the front housing 120 and / or the rear housing 130 have a mounting shaft 800 extending along a first axis, the partition 550 has a shaft hole 551, the mounting shaft 800 passes through a first opening 530, the shaft hole 551 and a second opening 540, and the shaft hole 551 is rotatably fitted with the mounting shaft 800.

[0063] The rotating connection between the mounting shaft 800 and the shaft hole 551 is achieved through the rotational engagement of the mounting shaft 800 and the housing assembly 100. When the user rotates the temperature probe 300, the shaft hole 551 rotates around the mounting shaft 800, thereby enabling the rotating shaft 500 and the temperature probe 300 to rotate together on the housing assembly 100. Furthermore, the first opening 530 and the second opening 540 also serve to allow the mounting shaft 800 to pass through the rotating shaft 500, so that only one additional shaft hole 551 needs to be opened in the partition 550 to achieve the purpose of the mounting shaft 800 passing through the rotating shaft 500 and rotatingly connecting with the rotating shaft 500.

[0064] Please refer to Figures 1-3 In one embodiment, the temperature detection device further includes a shaft sealing ring 900, which includes a first shaft sealing ring 910 and a second shaft sealing ring 920. The first shaft sealing ring 910 is disposed between the first opening 530 and the front housing 120 to seal the gap between the first opening 530 and the front housing 120. The second shaft sealing ring 920 is disposed between the second opening 540 and the rear housing 130 to seal the gap between the second opening 540 and the rear housing 130.

[0065] The gap between the first opening 530 and the front shell 120 is sealed by the first rotating shaft sealing ring 910, and the gap between the second opening 540 and the rear shell 130 is sealed by the second rotating shaft sealing ring 920. This makes it difficult for external dust and liquids to enter the first cavity 521 and the second cavity 522, which helps to protect the thermocouple wire 310 in the first cavity 521 and the switching component 400 in the second cavity 522, thereby improving the service life of the temperature detection device.

Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
