Description

Technical Field

[0001] The present application relates to the field of thermometer detectors, and in particular to a mechatronic temperature detector. Background Art

[0002] The integrated temperature detector is also called temperature transmitter. It mainly uses thermocouples and thermal resistors as temperature measuring elements. The output signal from the temperature measuring element is sent to the transmitter module. After being processed by circuits such as voltage stabilization and filtering, operational amplification, and nonlinear correction, it is converted into current and voltage signals and output as digital signals.

[0003] The current integrated temperature detector mainly includes a temperature transmitter body and a temperature detection probe. The temperature transmitter body is connected to the temperature detection probe. A control module with components is arranged inside the temperature transmitter body, and a battery is stored on the control module. In order to dissipate heat from the internal control module and battery, a plurality of heat dissipation holes are usually opened on the outer shell of the temperature transmitter body for heat dissipation.

[0004] However, in actual use, the heat dissipation efficiency of the heat dissipation holes is low. After long-term use, the control module and the battery are prone to damage, thereby affecting the detection accuracy of the temperature detector, so there is room for improvement.

[0007] By adopting the above technical solution, during the use of the temperature detector, when the temperature inside the shell is high, the feed pipe transports the heat dissipation medium to the heat dissipation pipe, and then discharges it from the discharge pipe.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a mechatronic temperature detector. Figure 1 and Figure 2 A mechatronic temperature detector includes a housing 1 and a temperature detection head 2, the temperature detection head 2 is connected to the housing 1, and a control module 3 matched with the temperature detection head 2 is arranged in the housing 1. A circulating heat dissipation component 4 is arranged in the housing 1, and the circulating heat dissipation component 4 includes a heat dissipation pipe 41, a feed pipe 42 and a discharge pipe 43. The heat dissipation pipe 41 is wound around the control module 3, and one end of the heat dissipation pipe 41 is connected to the feed pipe 42, and the other end is connected to the discharge pipe 43. The feed pipe 42 and the discharge pipe 43 extend out of the housing 1 and are externally connected to a storage box 5 containing a heat dissipation medium, and a circulating pump (not shown in the figure) is stored in the storage box 5. An extrusion component 6 for extruding the heat dissipation pipe 41 is arranged in the housing 1. The heat dissipation pipe 41 is in contact with the control module 3, and the heat dissipation medium exchanges heat with the control module 3 to dissipate heat for the control module 3. The extrusion assembly 6 extrude the heat dissipation pipe 41, which on the one hand increases the contact area between the heat dissipation pipe 41 and the control module 3, and on the other hand accelerates the flow rate of the heat dissipation medium and increases the circulation speed of the heat dissipation medium, so that the heat dissipation medium can dissipate heat for the control module 3 more stably, reducing the possibility of damage to the control module 3 due to excessive temperature, thereby improving the detection accuracy of the temperature detector.

[0021] Reference Figure 2 and Figure 3The extrusion assembly 6 includes a support platform 61, an extrusion rod 62 and an extrusion plate 63. The support platform 61 is mounted inside the housing 1. A clearance hole 611 is provided on the support platform 61. The extrusion rod 62 is rotatably connected in the clearance hole 611. The extrusion plate 63 is fixed to the end of the extrusion rod 62 away from the support platform 61, and a first torsion spring 621 is wound around the rotating shaft of the extrusion rod 62. The extrusion plate 63 is in contact with the heat dissipation pipe 41, and a control assembly 7 for controlling the extrusion rod 62 is provided in the housing 1. A temperature sensor 612 is provided on the side of the support platform 61 close to the control module 3. The heat dissipation pipe 41, the feed pipe 42 and the discharge pipe 43 are all configured as hoses.

[0022] In order to reduce the possibility of the extrusion plate 63 damaging the heat dissipation pipe 41, a moving groove 631 is provided on the extrusion plate 63, and an extrusion block 632 is slidably connected in the moving groove 631. A plurality of first springs 633 are provided in the moving groove 631, and one end of each first spring 633 is fixed to the bottom of the moving groove 631, and the other end is fixed to the extrusion block 632. An extrusion arc surface 634 is provided at one end of the extrusion block 632 away from the extrusion plate 63.

[0023] Reference Figure 2 The control assembly 7 includes a control rod 71, a connecting plate 72 and a control plate 73. The control rod 71 is slidably connected in the housing 1, the connecting plate 72 is fixed to the control rod 71, and the control plate 73 is rotatably connected to the connecting plate 72. There are two extrusion rods 62 arranged opposite to each other, and there are two control plates 73 arranged opposite to each other, and each control plate 73 corresponds to one extrusion rod 62. The control rod 71 extends out of the housing 1 and is connected to the driving assembly 8.

[0024] The driving assembly 8 includes a motor 81, a gear 82 and a rack 83. The motor 81 is fixed on the housing 1. The gear 82 is coaxially fixed on the output end of the motor 81. The rack 83 is fixed on one end of the control rod 71 outside the housing 1, and the gear 82 is meshed with the rack 83.

[0025] When the detection value of the temperature sensor 612 reaches the first threshold value, the external storage box 5 delivers the heat dissipation medium to the heat dissipation pipe 41 to dissipate heat for the control module 3. When the detection value of the temperature sensor 612 reaches the second threshold value (the second threshold value is the maximum operating temperature that the control module 3 can withstand), the motor 81 starts and drives the gear 82 to rotate, the gear 82 drives the rack 83 to move, and the rack 83 drives the control rod 71 to move. The control rod 71 drives the connecting plate 72 to move, and the connecting plate 72 drives the control plate 73 to rotate, so that the control plate 73 moves toward the extrusion rod 62. After the control plate 73 contacts the extrusion rod 62, the extrusion rod 62 rotates and drives the extrusion plate 63 and the extrusion block 632 to rotate. The extrusion block 632 contacts the heat dissipation pipe 41 and squeezes the heat dissipation pipe 41. At this time, the first spring 633 is in a compressed state. Under the action of the first spring 633, part of the impact force of the extrusion block 632 is absorbed, so that the extrusion block 632 is not easy to damage the heat dissipation pipe 41. At the same time, the extrusion arc surface 634 further reduces the possibility of damage to the heat pipe 41. At this time, under the action of the extrusion block 632 and the extrusion plate 63, the heat pipe 41 can be extruded, increasing the contact area between the heat pipe 41 and the control module 3, and accelerating the conveying speed of the heat dissipation medium in the heat pipe 41, so that the heat dissipation medium can dissipate heat to the control module 3 more stably, so that the control module 3 works more stably, thereby improving the detection accuracy of the temperature detector.

[0026] Reference Figure 2 In order to improve the stability of the control board 73 when it moves, a control wheel 731 is rotatably connected to the control board 73, and the control wheel 731 abuts against the support platform 61. When the control board 73 moves, the control wheel 731 rolls on the support platform 61, so that the sliding friction between the control board 73 and the support platform 61 is changed into rolling friction, which reduces the friction between the control board 73 and the support platform 61, so that the control board 73 can control the rotation of the extrusion rod 62 more stably.

[0027] Reference Figure 2 In order to facilitate the resetting of the control assembly 7, a booster assembly 9 is provided in the housing 1. The booster assembly 9 includes a support plate 91 and a booster plate 92. The support plate 91 is fixed to the inner wall of the housing 1, and the booster plate 92 is fixed to the control rod 71. A plurality of second springs 93 are fixed to the support plate 91, and one end of each second spring 93 away from the support plate 91 is connected to the booster plate 92.

[0028] When the control rod 71 moves toward the support platform 61, the control rod 71 drives the assisting plate 92 to move, and the second spring 93 is in a compressed state. When the control rod 71 is reset, the motor 81 controls the gear 82 to reverse, so as to drive the control rod 71 to reset. At the same time, under the action of the rebound force of the second spring 93, the assisting plate 92 is provided with assisting force, that is, the reset of the control rod 71 is provided with assisting force, so that the control rod 71 is reset more stably.

[0029] Reference Figure 2 and Figure 3 In order to further improve the heat dissipation effect in the housing 1, the housing 1 is connected with an air inlet pipe 11 and an air outlet pipe 12, and the air inlet pipe 11 and the air outlet pipe 12 are arranged opposite to the control module 3. A first support frame 13 and a second support frame 14 are fixed to the housing 1, the first support frame 13 is connected with the air inlet pipe 11, and the second support frame 14 is connected with the air outlet pipe 12. Fans 15 are arranged in the first support frame 13 and the second support frame 14, and the direction of the fan 15 in the first support frame 13 is opposite to the direction of the fan 15 in the second support frame 14.

[0030] The air inlet pipe 11 and the air outlet pipe 12 are both rotatably connected with a cover plate 16, and each of the air inlet pipe 11 and the air outlet pipe 12 corresponds to an extrusion plate 63. A connecting rope 161 is fixed to the cover plate 16, and one end of the connecting rope 161 away from the cover plate 16 is fixed to the extrusion plate 63 at the corresponding position, and a second torsion spring 17 is wound around the rotating shaft of the cover plate 16.

[0031] When the temperature in the housing 1 reaches the second threshold, the fan 15 starts, and the extrusion rod 62 rotates under the driving action of the control component 7, and the extrusion rod 62 drives the extrusion plate 63 at the corresponding position to rotate. The extrusion plate 63 pulls the connecting rope 161, and the connecting rope 161 drives the cover plate 16 at the corresponding position to rotate. The air inlet pipe 11 transports the outside air into the housing 1, and the air outlet pipe 12 transports the air inside the housing 1 to the outside of the housing 1, realizing the function of air circulation in the housing 1, further reducing the possibility of damage to the control module 3 due to excessive temperature, thereby further improving the detection accuracy of the temperature detector.

[0032] Reference Figure 2 A filter 18 is provided on both the first support frame 13 and the second support frame 14. The filter 18 filters external impurities, reducing the possibility of external impurities damaging the fan 15, so that the fan 15 can circulate the air in the housing 1 more stably.

[0033] The implementation principle of a mechatronic temperature detector in the embodiment of the present application is as follows: the heat dissipation medium in the heat dissipation pipe 41 performs heat exchange with the control module 3 to dissipate heat for the control module 3. When the temperature in the housing 1 exceeds the set second threshold value, the drive component 8 drives the control component 7 to start, so as to drive the control board 73 to move, and the control board 73 contacts the extrusion rod 62 to drive the extrusion rod 62 to rotate. The extrusion rod 62 drives the extrusion plate 63 and the extrusion block 632 to rotate to squeeze the heat dissipation pipe 41. When the heat dissipation pipe 41 is squeezed, the contact area between the heat dissipation pipe 41 and the control module 3 is increased, and the flow rate of the heat dissipation medium in the heat dissipation pipe 41 is accelerated to improve the heat exchange efficiency of the heat dissipation medium, that is, to improve the heat dissipation effect on the control module 3, and further reduce the possibility of damage to the control module 3 due to excessive temperature. And the air inlet pipe 11 cooperates with the air outlet pipe 12 to realize the function of air circulation in the housing 1, further reducing the possibility of excessive temperature in the housing 1, thereby improving the detection accuracy of the temperature detector.

[0034] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
