Technical Field

[0001] This application relates to the field of auxiliary tool technology, and in particular to a platinum resistance testing device. Background Technology

[0002] Platinum resistance thermometers (PTS) are high-precision sensors that measure temperature by utilizing the change in resistance of platinum metal with temperature. They are widely used in industry, medicine, meteorology, and other fields. After a period of use, PTS tests are typically required to ensure the accuracy of temperature measurements. However, current PTS testing devices are inconvenient for users to operate, resulting in lengthy testing times. Utility Model Content

[0003] This application addresses the problem that existing platinum resistance testing devices are inconvenient for users to operate, and proposes a platinum resistance testing device that is easy for users to operate.

[0004] A platinum resistance thermometer, comprising:

[0005] The housing has an internal cavity, and the housing has a mounting part and an opening arranged opposite to each other along a first direction. The opening communicates with the cavity, and at least a portion of the mounting part is located inside the cavity and is used to insert a thermometer.

[0006] A mounting element is sealed in the opening, with at least a portion of the mounting element located within the receiving cavity. The mounting element allows the platinum resistance thermometer to be tested to be inserted into the receiving cavity and connects the housing to the platinum resistance thermometer to be tested.

[0007] In one embodiment, the mounting member has a sealed state that blocks the opening and a detection state that exposes the opening, wherein, in the detection state, the mounting member allows the platinum resistance to be tested to pass through and connects the housing to the platinum resistance to be tested.

[0008] In one embodiment, the mounting component includes a check valve and a connector, one end of which is detachably connected to the check valve and the other end of which is connected to the housing. The check valve switches between a sealed state and a detection state, and is connected to the platinum resistance thermometer in the detection state.

[0009] In one embodiment, the mounting element further includes a seal installed between the check valve and the connector.

[0010] In one embodiment, the mounting element is detachably connected to the housing.

[0011] In one embodiment, the mounting component is integrally formed with the housing and together with the housing, they enclose a sealed cavity.

[0012] In one embodiment, the mounting portion is located within the receiving cavity and is integrally formed with the housing. The mounting portion and the housing together enclose a closed chamber.

[0013] In one embodiment, the housing is further provided with a water injection section, which is disposed on the same side as the mounting section and communicates with the receiving cavity. The platinum resistance detection device also includes a sealing member, which is detachably connected to the water injection section.

[0014] In one embodiment, the housing has a through hole, which is configured as the mounting portion.

[0015] In one embodiment, the housing is configured as a bottle-shaped structure or a bag-shaped structure.

[0016] The mounting components of the aforementioned platinum resistance thermometer are sealed at the opening of the housing, which improves the sealing between the mounting components and the housing. This reduces the probability that water from inside the housing will seep out and flow onto the material conveying line during the testing process, thus affecting the product's process moisture content. Furthermore, the thermometer and the platinum resistance thermometer to be tested can be connected together via the platinum resistance thermometer, eliminating the need for the user to constantly hold both during operation, thus improving the ease of use of the platinum resistance thermometer.

[0032] Please see Figures 1 to 3 This application provides a platinum resistance thermometer 100, which includes a housing 10 and a mounting member 20. The housing 10 has a receiving cavity 11 inside, and a mounting portion 12 and an opening 13 disposed opposite each other along a first direction X. The opening 13 communicates with the receiving cavity 11, and at least a portion of the mounting portion 12 is located within the receiving cavity 11 and is used to insert a thermometer 200. The mounting member 20 is sealed at the opening 13, and at least a portion of the mounting member 20 is located within the receiving cavity 11. The mounting member 20 allows the platinum resistance thermometer 300 to be tested to be inserted into the receiving cavity 11, and connects the housing 10 to the platinum resistance thermometer 300.

[0033] The housing 10 can be made of a high-temperature resistant material because hot water will be injected into the housing 10 during use to facilitate the testing of the platinum resistance thermometer 300. Therefore, using a high-temperature resistant material to make the housing 10 can reduce the probability of deformation of the housing 10 due to high temperatures. The connection between the mounting part 20 and the housing 10 can be, but is not limited to, threaded connection, snap-fit, etc.

[0034] The working principle of the platinum resistance thermometer 100 is explained below.

[0035] In use, hot water can be poured into the receiving cavity 11 of the housing 10. Then, a thermometer 200 is inserted into the mounting part 12 to detect the water temperature in the receiving cavity 11. Next, the platinum resistance thermometer 300 to be tested can be inserted into the mounting part 20 and extended into the receiving cavity 11 through the mounting part 20 to detect the water temperature in the receiving cavity 11. When the data measured by the platinum resistance thermometer 300 is equal to the data measured by the thermometer 200, it indicates that the platinum resistance thermometer 300 is functioning normally; otherwise, the platinum resistance thermometer 300 needs to be calibrated.

[0036] Because the mounting component 20 is sealed at the opening 13 of the housing 10, the sealing performance between the mounting component 20 and the housing 10 is improved, reducing the probability that water inside the housing 10 will seep out and flow onto the material conveying line during the testing process, thus affecting the product's process moisture content. Furthermore, the thermometer 200 and the platinum resistance thermometer 300 to be tested can be connected together through the platinum resistance testing device 100, eliminating the need for the user to constantly hold both the thermometer 200 and the platinum resistance thermometer 300 during use, thus improving the ease of use of the platinum resistance testing device 100.

[0037] In some embodiments, the mounting member 20 has a sealed state with the opening 13 blocked and a detection state with the opening 13 exposed. In the detection state, the mounting member 20 allows the platinum resistance resistor 300 to pass through and connects the housing 10 to the platinum resistance resistor 300.

[0038] This can be understood as follows: the mounting component 20 is positioned at the opening 13. When the platinum resistance thermometer 300 to be tested is not inserted into the mounting component 20, the mounting component 20 is in a sealed state, blocking the opening 13. In this sealed state, water in the receiving cavity 11 will not leak out through the opening 13. When it is necessary to test the platinum resistance thermometer 300, it is inserted into the mounting component 20 to detect the water temperature in the receiving cavity 11. Although the mounting component 20 does not completely block the opening 13 at this time, the platinum resistance thermometer 300 blocks the opening 13, thus preventing water from leaking out of the receiving cavity 11 through the opening 13.

[0039] This setup simplifies the assembly of the platinum resistance thermometer 300 and the platinum resistance testing device 100, and improves the ease of installation of the platinum resistance thermometer 300.

[0040] Specifically, such as Figure 4As shown. In some embodiments, the mounting component 20 includes a check valve 21 and a connector 22. One end of the connector 22 is detachably connected to the check valve 21, and the other end is connected to the housing 10. The check valve 21 switches between a sealing state and a detection state, and is connected to a platinum resistance thermometer in the detection state.

[0041] For example, in Figure 4 In the example shown, a duckbill valve can be used as the check valve 21, and a nut as the connector 22. The duckbill valve is connected to the housing 10 by the nut. The duckbill valve is a flexible rubber check valve 21, which reliably opens and closes automatically based on medium pressure. That is, the duckbill valve opens when an external force is applied and automatically closes when the external force is removed.

[0042] This design simplifies the sealing and exposure of the opening 13 of the mounting component 20. Furthermore, the detachable connection between the connector 22 and the check valve 21 allows for easy replacement of either component if either is damaged, reducing maintenance costs compared to replacing both. Additionally, the check valve 21 can be adjusted to fit the platinum resistance thermometer under test without compromising the sealing performance of the mounting component 20.

[0043] It is understandable that the connection between the connector 22 and the check valve 21 can also be a snap-fit ​​connection, a key connection, or other methods, which will not be described in detail here.

[0044] For more details, please continue reading. Figure 4 In some embodiments, the mounting member 20 further includes a seal 23, which is installed between the check valve 21 and the connector 22. The seal 23 may be configured as an annular sealing ring to seal the peripheral connection between the check valve 21 and the connector 22.

[0045] This configuration improves the overall sealing performance of the mounting component 20 by enhancing the sealing between its various parts.

[0046] In some embodiments, the mounting component 20 is detachably connected to the housing 10.

[0047] For example, both the mounting component 20 and the housing 10 are threaded, and they are connected by threads. Alternatively, the mounting component 20 and the housing 10 are connected by a snap-fit ​​connection. When either the mounting component 20 or the housing 10 is damaged, the damaged part can be replaced with a new one. Compared to replacing both the mounting component 20 and the housing 10 together, only the damaged part is replaced, which reduces the maintenance cost of the platinum resistance testing device 100.

[0048] like Figure 5 and Figure 6As shown, in some embodiments, the mounting member 20 is integrally formed with the housing 10 and together with the housing 10 encloses a closed cavity.

[0049] For example, the mounting member 20 is connected to the edge of the opening 13 and is entirely located within the receiving cavity 11. Because the mounting member 20 and the housing 10 together form a closed chamber, there is no area between the mounting member 20 and the housing 10 where the water in the receiving cavity 11 can reach. After the platinum resistance thermometer 300 to be tested is inserted into the mounting member 20, the platinum resistance thermometer 300 will not directly contact the water in the receiving cavity 11, and the water temperature in the receiving cavity 11 can be detected through the mounting member 20.

[0050] This design not only improves the sealing performance of the platinum resistance testing device 100, but also enhances the connection stability between the mounting component 20 and the housing 10, thereby improving the installation stability of the platinum resistance 300 under test. In addition, it simplifies the manufacturing process of the mounting component 20.

[0051] like Figure 6 As shown, in some embodiments, the mounting part 12 is located inside the receiving cavity 11 and is integrally formed with the housing 10. The mounting part 12 and the housing 10 together enclose a closed cavity.

[0052] In other words, after the thermometer 200 is inserted into the mounting part 12, the temperature part will not directly contact the water in the receiving cavity 11, and the water temperature in the receiving cavity 11 will be detected through the mounting part 12.

[0053] This design not only improves the sealing performance of the platinum resistance testing device 100, but also enhances the connection stability between the mounting part 12 and the housing 10, thereby improving the installation stability of the thermometer 200. In addition, it simplifies the manufacturing process of the mounting part 12.

[0054] To improve the detection accuracy of the platinum resistance testing device 100, the mounting part 12 and the mounting component 20 can be made of the same material, and the mounting part 12 and the mounting component 20 can be enclosed with the housing 10 to form a closed chamber, so that the thermometer 200 and the platinum resistance 300 to be tested have the same detection environment.

[0055] When the mounting part 12 and the mounting component 20 are together with the housing 10 to form a closed chamber, the housing 10 can be improved to facilitate water injection.

[0056] For example, such as Figure 7 As shown, in some embodiments, the housing 10 is further provided with a water injection section 14, which is disposed on the same side as the mounting section 12 and communicates with the receiving cavity 11. The platinum resistance detection device 100 also includes a sealing member 30, which is detachably connected to the water injection section 14.

[0057] The water injection section 14 may protrude from the surface of the housing 10, allowing the user to inject water into the receiving cavity 11. After water injection is complete, the sealing member 30 is installed on the water injection section 14 to seal it, reducing the probability that water in the receiving cavity 11 will leak out through the water injection section 14 and flow onto the material conveying line, thereby affecting the product's process moisture content. The connection method between the sealing members 30 may be, but is not limited to, threaded connection or snap-fit, facilitating quick installation or removal of the sealing member 30 from the water injection section 14 by the user.

[0058] like Figure 1 As shown, in some embodiments, the housing 10 has a through hole, which is configured as a mounting portion 12.

[0059] The thermometer 200 is inserted into the mounting part 12, allowing it to directly contact and measure the water in the receiving cavity 11. This design simplifies the structure of the mounting part 12 and reduces its manufacturing difficulty. Furthermore, users can directly inject water into the receiving cavity 11 through the mounting part 12, thus using it as a water inlet and enriching its functionality.

[0060] In some embodiments, the housing 10 is configured as a bottle-shaped structure or a bag-shaped structure.

[0061] When the housing 10 has a bottle-shaped structure, its own rigidity can be increased. When inserted into the platinum resistance thermometer 300 to be tested, the platinum resistance testing device 100 can stand upright on the plane where the platinum resistance thermometer 300 is located. When the housing 10 has a bag-shaped structure, the housing 10 can be rolled up for storage when the platinum resistance testing device 100 is not in use, reducing the space occupied by the platinum resistance testing device 100.

[0062] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0063] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
