Description

Technical Field

[0001] The utility model relates to the technical field of sensors, in particular to a thermal control sensor. Background Art

[0002] A sensor is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The existence and development of sensors have given objects senses such as touch, taste and smell, making objects come alive. Sensors are an extension of human five senses. Sensors have the characteristics of miniaturization, digitization, intelligence, multi-function, systematization and networking. They are the primary link to realize automatic detection and automatic control. Sensors include thermal control sensors. Most of the existing thermal control sensors have monitoring effects, but most of the thermal control sensors have average sealing effects. Therefore, there is a special need for a thermal control sensor with temperature monitoring function.

[0003] Although most existing thermal control sensors have monitoring effects, most of them have average sealing effects. This may cause leakage at the connection point between the sensor and the object to be measured during use, and may also cause heat leakage inside the container, which is not conducive to the use of thermal control sensors. On the one hand, it leads to large measurement errors of thermal control sensors, and on the other hand, heat leakage will also reduce the service life of the sensor. Utility Model Content

[0038] Although most of the existing thermal control sensors have monitoring effects, most of them have average sealing effects. Therefore, when in use, leakage may occur at the connection point between the sensor and the object to be measured, and heat leakage may occur inside the container, which is not conducive to the use of the thermal control sensor. On the one hand, it leads to large measurement errors of the thermal control sensor, and on the other hand, heat leakage will also reduce the service life of the sensor. Specifically, the temperature sensing part of the thermal control sensor can work normally at the operating temperature for a long time, but the wiring part cannot work for a long time under high temperature conditions. Under high temperature conditions, the aging speed of the wiring terminals and cables of the wiring part is likely to be accelerated, resulting in a reduction in service life.

[0039] The utility model embodiment proposes a thermal control sensor probe and a thermal control sensor for inserting into an object to be measured to monitor the temperature based on the sealing principle, wherein the sealing principle is mainly to use a seal to seal the part where the connecting column and the container interact, and the seal can be a gasket.

[0040] The thermal control sensor of this embodiment includes a thermal control sensor probe and a sealing mechanism, wherein the sealing mechanism includes a first sealing ring and a second sealing ring, and the thermal control sensor probe includes a thermal control sensor, a connecting column and a sensing column fixedly connected in sequence; the lower surface of the thermal control sensor is fixedly connected to the connecting column, the surface of one end of the connecting column is fixedly connected to the sensing column, and the outer surface of the connecting column is provided with a sealing mechanism, the first sealing ring is provided at one end connected to the sensing column, and the second sealing ring is provided at one end connected to the thermal control sensor; the first sealing ring is used to seal the internal connection point after the thermal control sensor is connected to the object to be measured, and the second sealing ring is used to seal the external connection point after the thermal control sensor is connected to the object to be measured.

[0041] In some embodiments, a projected area of ​​the thermal control sensor along the axis of the thermal control sensor probe is larger than a projected area of ​​the connecting column along the axis of the thermal control sensor probe.

[0042] In other embodiments, the projection area of ​​the connecting column along the axis of the thermal control sensor probe is larger than the projection area of ​​the sensing column along the axis of the thermal control sensor probe.

[0043] The outer surface of the sensing column is coated with a first coating, preferably, the first coating is a corrosion-resistant coating, and the material of the first coating is mainly synthetic resin; the outer surface of the sensing column is coated with a second coating, preferably, the second coating is a waterproof coating, and the material of the second coating is mainly acrylic acid.

[0044] Preferably, the sealing mechanism further comprises a first placement groove matched with the first sealing ring, the outer surface of the connecting column is provided with the first placement groove, specifically arranged on the outer surface of one end of the connecting column connected to the sensing column, the inner surface of the first placement groove is provided with the first sealing ring, the inner wall size of the first placement groove matches the outer side of the first sealing ring, that is, the first sealing ring and the first placement groove have an interference fit, and the minimum inner wall diameter of the first placement groove is larger than the inner diameter of the first sealing ring in the natural state. The material of the first sealing ring is silicone rubber.

[0045] Preferably, the sealing mechanism also includes a second placement groove that cooperates with the second sealing ring. The second placement groove is opened on the outer surface of the connecting column, specifically arranged on the outer surface of one end of the connecting column connected to the thermal control sensor, and the inner surface of the second placement groove is tightly fitted with the second sealing ring.

[0046] The inner wall size of the second placement groove matches the outer side of the second sealing ring, that is, the second sealing ring and the second placement groove have an interference fit, and the minimum inner wall diameter of the second placement groove is larger than the inner diameter of the second sealing ring in the natural state. The material of the second sealing ring is silicone rubber.

[0047] The embodiment of the utility model further proposes a thermal control sensor, which adopts the thermal control sensor probe. The upper surface of the thermal control sensor is fixedly connected to a controller, and a display screen is installed on one side surface of the controller.

[0048] Compared with the existing thermal control sensor, the embodiment of the utility model has the following beneficial effects:

[0049] The thermal control sensor with temperature monitoring function has a first sealing ring and a second sealing ring. When the thermal control sensor needs to be used, the sensing column is first placed inside the object to be measured through the connecting column. Then, the first sealing ring can be used to seal the internal connection point after the thermal control sensor is connected to the object to be measured. Then, the second sealing ring can be used to seal the external connection point after the thermal control sensor is connected to the object to be measured. Heat leakage is avoided during the monitoring operation of the thermal control sensor, thereby improving the monitoring accuracy of the thermal control sensor. At the same time, the leaked heat is prevented from increasing the ambient temperature of the wiring part of the thermal control sensor, thereby avoiding the situation that the aging speed of the wiring terminals, cables and other components of the wiring part is accelerated under high temperature conditions, thereby extending the service life of the thermal control sensor.

[0050] By setting the projection area of ​​the connecting column along the axis direction of the thermal control sensor probe larger than the projection area of ​​the sensing column, the sealing performance of the first sealing ring on the internal connection point between the thermal control sensor and the object to be measured is further improved, thereby further improving the monitoring accuracy and service life of the thermal control sensor.

[0051] Furthermore, the first sealing ring is installed inside the first placement groove, further improving the sealing of the internal connection point between the thermal control sensor probe and the object to be measured, thereby further improving the monitoring accuracy and service life of the thermal control sensor. The second sealing ring is installed inside the second placement groove, further improving the sealing of the external connection point between the thermal control sensor probe and the object to be measured, thereby further improving the monitoring accuracy and service life of the thermal control sensor.

[0052] By providing a waterproof coating on the surface of the sensing column, the thermal control sensor can be prevented from being damaged due to the fact that the object to be measured is liquid when the thermal control sensor is in use, thereby extending the service life of the thermal control sensor.

[0053] By providing an anti-corrosion coating on the surface of the sensing column, the thermal control sensor can be prevented from being corroded due to being frequently used in liquids, thereby extending the service life of the thermal control sensor.

[0054] A controller is provided on the thermal control sensor, and a display screen is provided on the controller, so that the measured temperature of the thermal control sensor is converted into a numerical value through the controller and visualized on the display screen.

[0055] By setting a controller on the thermal control sensor and setting a display screen on the controller, the temperature of the thermal control sensor can be converted into a numerical value through the controller and visualized on the display screen, thus completing a thermal control sensor with temperature monitoring function.

[0056] Example:

[0057] like Figure 1-3 As shown, the thermal control sensor of this embodiment is as follows Figure 1 As shown, it includes a thermal control sensor probe and a sealing mechanism, wherein the sealing mechanism includes a first placement groove 63, a first sealing ring 61, a second placement groove 64 and a second sealing ring 62, and the thermal control sensor probe is as shown in FIG. Figure 2 As shown, it includes a thermal control sensor 1, a connecting column 2 and a sensing column 5 which are fixedly connected in sequence; the lower surface of the thermal control sensor 1 is fixedly connected with the connecting column 2, the upper surface of the thermal control sensor 1 is fixedly connected with the controller 3, a display screen 4 is installed on one side of the controller 3, specifically, a display screen 4 is installed on the other side of the controller 3 connected to the thermal control sensor 1, one end surface of the connecting column 2 is fixedly connected with the sensing column 5, and a sealing mechanism is provided on the outer side surface of the connecting column 2. Figure 4 As shown, the outer surface of the sensing column 5 is coated with a first coating 7 , and the outer surface of the sensing column 5 is coated with a second coating 8 .

[0058] Furthermore, the first coating 7 is a corrosion-resistant coating, and the material of the first coating 7 is mainly synthetic resin. The second coating 8 is a waterproof coating, and the material of the second coating 8 is mainly acrylic. By setting the second coating 8 as a waterproof coating, the thermal control sensor 1 can be prevented from being damaged due to the object to be measured being liquid during use. By setting the material of the first coating 7 mainly being synthetic resin, the thermal control sensor 1 can be prevented from being corroded due to being frequently used in liquids.

[0059] Furthermore, the sealing mechanism such as Figure 3 As shown, it includes a first placement groove 63, a first sealing ring 61, a second placement groove 64 and a second sealing ring 62. The first placement groove 63 is opened on the outer surface of the connecting column 2, and the first sealing ring 61 is installed on the inner surface of the first placement groove 63. The second placement groove 64 is opened on the outer surface of the connecting column 2, and the second sealing ring 62 is tightly fitted on the inner surface of the second placement groove 64. When the thermal control sensor 1 needs to be sealed after being installed on other objects (i.e., the object to be tested), firstly, through the setting of the first sealing ring 61, the first sealing ring 61 can seal the internal connection point after the thermal control sensor 1 is connected to the other object (i.e., the object to be tested), and then the first sealing ring 61 is installed in the first placement groove 63; then, through the setting of the second sealing ring 62, the second sealing ring 62 can seal the external connection point after the thermal control sensor 1 is connected to the other object, and then the second sealing ring 62 is installed in the second placement groove 64.

[0060] Furthermore, the inner wall size of the first placement groove 63 is consistent with the outer side of the first sealing ring 61 . The material of the first sealing ring 61 is silicone rubber. The heat resistance of the first sealing ring 61 can be improved by using silicone rubber as the material of the first sealing ring 61 .

[0061] Furthermore, the inner wall size of the second placement groove 64 is consistent with the outer side of the second sealing ring 62. The material of the second sealing ring 62 is silicone rubber. The heat resistance of the second sealing ring 62 can be improved by setting the material of the second sealing ring 62 to be silicone rubber.

[0062] The working principle of the thermal control sensor of this embodiment is as follows:

[0063] When the thermal control sensor 1 needs to be used, first, the sensing column 5 is placed inside the object to be tested through the connecting column 2, and then the first sealing ring 61 is set, the first sealing ring 61 can seal the internal connection point after the thermal control sensor 1 is connected to other objects, and then the first sealing ring 61 is installed inside the first placement groove 63, and then the second sealing ring 62 is set, the second sealing ring 62 can seal the external connection point after the thermal control sensor 1 is connected to other objects, and then the controller 3 can convert the temperature of the thermal control sensor 1 into a numerical value to be reflected on the display screen 4, and the second coating 8 is set as a waterproof coating, so that when in use, the thermal control sensor 1 can be prevented from being damaged due to the situation that the object to be tested is liquid, and the material of the first coating 7 is mainly synthetic resin, so that the thermal control sensor 1 can be prevented from being corroded due to being frequently used in liquid, and the first placement groove 63 is smaller than the overall thread groove, and because the first sealing ring 61 is made of rubber, it will not affect the normal use of the thermal control sensor 1.

[0064] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For technicians in the technical field to which the present invention belongs, several equivalent substitutions or obvious variations can be made without departing from the concept of the present invention, and the performance or use is the same, which should be regarded as belonging to the protection scope of the present invention.
