[0036] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious 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 are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

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

[0038] This embodiment provides a temperature detection device.

[0039] Please refer to Figure 1-10 The temperature detection device includes a housing assembly 100 , a circuit board 200 , a temperature probe 300 , a switch component 400 and a rotating shaft component 500 .

[0040] Please refer to Figure 1-4 , 9 and 10, a display screen 110 is provided on the housing assembly 100, a circuit board 200 is provided in the housing assembly 100, and the circuit board 200 is electrically connected to the display screen 110. A temperature probe 300 is used for temperature detection, and the temperature probe 300 has a thermocouple wire 310. A switch 400 is electrically connected to the display screen 110, and the switch 400 is used to control the display screen 110 to turn on when triggered. The temperature probe 300 is rotatably connected to the housing assembly 100 through a rotating shaft 500, and the temperature probe 300 can rotate relative to the housing assembly 100 to achieve extension and folding, and the temperature probe 300 can trigger the switch 400 when it rotates to form a predetermined angle with the housing assembly 100. The rotating shaft 500 and / or the housing assembly 100 form an installation cavity 520, and a partition 550 is provided in the installation cavity 520, and the partition 550 divides the installation cavity 520 into a first cavity 521 and a second cavity 522. The thermocouple wire 310 extends through the first cavity 521 to be electrically connected to the circuit board 200 , and the switch element 400 is disposed in the second cavity 522 .

[0041] Please refer to Figure 1-4, 9 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 achieve extension, so that the temperature probe 300 can be inserted into the object or environment where the temperature needs to be detected. And the switch 400 will be triggered during the rotation and expansion of the temperature probe 300, so that the display screen 110 is turned on, and the display screen 110 is at least used to display the temperature value detected by the temperature probe 300 after it is turned on. That is, the user only needs to perform an operation of expanding the temperature probe 300 to additionally achieve the effect of turning on the display screen 110, so that the user can operate the temperature detection device more conveniently. In addition, since the thermocouple wire 310 and the switch 400 are respectively located in the first cavity 521 and the second cavity 522 that are isolated from each other, when the user rotates the temperature probe 300, the thermocouple wire 310 and the switch 400 will not interfere with each other, which is conducive to improving the service life of the temperature detection device, especially to improving the total number of times the temperature probe 300 can be rotated, expanded and folded relative to the housing assembly 100 through the rotating shaft 500.

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

[0043] Specifically, the installation cavity 520 can be formed by the rotating shaft member 500 and the shell assembly 100 together, or it can be formed by one of the rotating shaft member 500 and the shell assembly 100. As long as the installation cavity 520 is separated into the first cavity 521 and the second cavity 522 by the partition 550, the mutual interference between the thermocouple wire 310 and the switch member 400 can be avoided through spatial isolation.

[0044] It should be noted that the above-mentioned "predetermined angle" can be a single angle value or an angle range. For example, the switch member 400 can be triggered when the temperature probe 300 rotates to form an angle of 175° with the housing assembly 100, or the switch member 400 is kept in the state of being triggered when the temperature probe 300 rotates to form an angle of 170° to 180° with the housing assembly 100. Of course, the above-mentioned specific angles are only examples, and 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 Figure 1-4, 9 and 10, in one embodiment, the temperature probe 300 and the rotating shaft 500 can rotate around the first axis on the housing assembly 100, and the rotating shaft 500 includes a rotating shaft side wall 510 and a partition 550, and the rotating shaft side wall 510 is enclosed around 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] The shaft side wall 510 is enclosed around the first axis to form the installation cavity 520, and the partition 550 is connected to the inner wall of the installation cavity 520, so that the installation cavity 520 is divided into a first cavity 521 and a second cavity 522 isolated from each other by the partition 550. Since the first cavity 521 and the second cavity 522 are respectively located on opposite sides of the partition 550, the thermocouple wire 310 and the switch element 400 will not cross the partition 550 to interfere with each other. For details, please refer to Figure 2 , the first axis can be regarded as Figure 2 The temperature probe 300 and the rotating shaft 500 may be fixedly connected by bonding, screw connection or other suitable means, so that the temperature probe 300 and the rotating shaft 500 can be synchronously rotated around the first axis on the housing assembly 100 .

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

[0048] The partition 550 physically separates the thermocouple wire 310 and the switch element 400 in the extending direction of the first axis, thereby preventing the thermocouple wire 310 and the switch element 400 from interfering with each other when the rotating shaft 500 rotates around the first axis. In other implementations, the first cavity 521, the partition 550, and the second cavity 522 may also be arranged in sequence along a direction perpendicular to the first axis.

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

[0050] When using the temperature detection device, the user's line of sight is toward the front shell 120 of the housing assembly 100 to observe the information displayed on the display screen 110. Since the rotating shaft member 500 is installed between the front shell 120 and the rear shell 130, the rotating shaft member 500 is rotatably installed from opposite sides of the rotating shaft member 500 through the front shell 120 and the rear shell 130.

[0051] Please refer to Figure 1-4, 9 and 10, in one embodiment, a first opening 530 is provided on a side of the rotating shaft 500 facing the front shell 120, the first opening 530 is communicated with the first cavity 521, and the front shell 120 covers the first opening 530. A second opening 540 is provided on a side of the rotating shaft 500 facing the rear shell 130, the second opening 540 is communicated with the second cavity 522, and the rear shell 130 covers the second opening 540.

[0052] On the one hand, when assembling the temperature detection device, the first opening 530 connects the first cavity 521 with the external environment, and the second opening 540 connects the second cavity 522 with the external environment, which is convenient for the staff to install parts from the first opening 530 into the first cavity 521, and also convenient for the staff to install parts from the second opening 540 into the second cavity 522. For example, the staff can easily install the thermocouple wire 310 into the first cavity 521 through the first opening 530, and can also install the switch 400 into the second cavity 522 through the second opening 540. On the other hand, by covering the first opening 530 with the front shell 120 and covering the second opening 540 with the rear shell 130, the surface of the temperature detection device is smoother, and it is beneficial to protect the parts in 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 then extends to be connected to the circuit board 200 , and the circuit of the switch element 400 passes through the rear shell 130 and then extends to be connected to the circuit board 200 .

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

[0054] When the user rotates the rotating shaft 500 and the temperature probe 300, the triggering member 600 and the switch member 400 can be driven to rotate relative to each other, and when the temperature probe 300 rotates to form a predetermined angle with the housing assembly 100, the triggering member 600 contacts the switch member 400, thereby triggering the switch member 400. That is, the switch member 400 is triggered by the contact between the triggering member 600 and the switch member 400, so the switch member 400 can use a mechanical switch that can be triggered by pressure, and the use of a mechanical switch is conducive to ensuring the reliability of the switch member 400. In addition, since the triggering member 600 and the thermocouple wire 310 are arranged in different cavities, the triggering member 600 and the thermocouple wire 310 will not interfere with each other, so that the triggering member 600 can trigger the switch member 400 more smoothly and stably.

[0055] Specifically, the switch member 400 may be connected to the housing assembly 100, and the trigger member 600 may be connected to the shaft member 500. When the user rotates the shaft member 500, the trigger member 600 is driven to rotate relative to the switch member 400, so as to trigger the switch member 400. Of course, the switch member 400 may also be connected to the shaft member 500, and the trigger member 600 may be connected to the housing assembly 100, as long as the rotation of the shaft member 500 can drive the switch member 400 and the trigger member 600 to move relative to each other, thereby triggering the switch member 400.

[0056] Please refer to Figure 3-8 In one embodiment, the trigger member 600 is protruded from the partition 550, and the trigger member 600 is in an arc shape around the first axis, and the switch member 400 has a conducting portion 410 facing the trigger member 600. When the temperature probe 300 rotates to form a predetermined angle with the housing assembly 100, the trigger member 600 squeezes the conducting portion 410 to make the internal circuit of the switch member 400 conductive.

[0057] When the user rotates the temperature probe 300 to form a predetermined angle with the housing assembly 100, the trigger member 600 squeezes the conductive portion 410 of the switch member 400, so that the switch member 400 is triggered. Since the trigger member 600 is configured as 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, so that the rotating shaft member 500 can drive the trigger member 600 to rotate more stably when it moves. On the other hand, after the arc-shaped trigger member 600 contacts the conductive portion 410 of the switch member 400, when the rotating shaft member 500 continues to rotate at an angle not greater than the center angle of the arc, the arc-shaped trigger member 600 can maintain a state of contact with the conductive portion 410, so that the switch member 400 remains in a triggered state, and then the display screen 110 remains in a powered-on state.

[0058] Please refer to Figure 1-39. In 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 part of the thermocouple wire 310 is fixed in the first cavity 521 by the wire positioning member 700, so that the thermocouple wire 310 is neatly arranged in the first cavity 521, thereby facilitating wiring and maintenance. For example, the thermocouple wire 310 can be arranged around the inner wall of the first cavity 521, and then the thermocouple wire 310 is extended to the outside of the first cavity 521. Specifically, the wire positioning member 700 can be a buckle structure, a binding structure or other suitable wire positioning structure.

[0060] Please refer to Figure 1-3 , 9 and 10, in one embodiment, the housing assembly 100 further includes a middle frame housing 140, the middle frame housing 140 is disposed between the front housing 120 and the rear housing 130, and the opposite sides of the middle frame housing 140 are respectively connected to the front housing 120 and the rear housing 130. The front housing 120, the rear housing 130 and the middle frame housing 140 all have first ends disposed opposite to each other, the first end of the middle frame housing 140 has a clearance groove 141, and at least part of the rotating shaft 500 is movably disposed in the clearance groove 141. The first end of the front housing 120 covers the first opening 530, and the first end of the rear housing 130 covers the second opening 540.

[0061] The front shell 120 and the rear shell 130 are connected as a whole through the middle frame shell 140, so that the structure of the shell assembly 100 is more stable. The space for installing the rotating shaft 500 on the middle frame shell 140 is made available through the clearance groove 141, so that it is convenient to install the rotating shaft 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, so that the surface of the temperature detection device is smoother, and it is beneficial to protect the components in the first cavity 521 and the second cavity 522.

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

[0063] The rotational connection between the shaft 500 and the housing assembly 100 is realized by the rotational cooperation between the installation shaft 800 and the shaft hole 551. When the user rotates the temperature probe 300, the shaft hole 551 is driven to rotate around the installation shaft 800, thereby realizing the rotation of the shaft 500 and the temperature probe 300 on the housing assembly 100. The first opening 530 and the second opening 540 also play the role of allowing the installation shaft 800 to pass through the shaft 500, so that only an additional shaft hole 551 is provided on the partition 550 to realize the purpose of the installation shaft 800 passing through the shaft 500 and being rotationally connected with the shaft 500.

[0064] Please refer to Figure 1-3 , 9 and 10, in one embodiment, the temperature detection device further includes a shaft sealing ring 900, and the shaft sealing ring 900 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 shell 120, and is used to seal the gap between the first opening 530 and the front shell 120. The second shaft sealing ring 920 is disposed between the second opening 540 and the rear shell 130, and is used to seal the gap between the second opening 540 and the rear shell 130.

[0065] The first rotating shaft sealing ring 910 is used to seal the gap between the first opening 530 and the front shell 120, and the second rotating shaft sealing ring 920 is used to seal the gap between the second opening 540 and the rear shell 130, so that external dust and liquid are not easy to enter the first cavity 521 and the second cavity 522, which is beneficial to protecting the thermocouple wire 310 in the first cavity 521 and the switch component 400 in the second cavity 522, and further beneficial to improving the service life of the temperature detection device.

[0066] The above specific examples are used to illustrate the present invention, which is only used to help understand the present invention and is not intended to limit the present invention.
