Description

Technical Field

[0001] The utility model relates to the technical field of temperature measurement, in particular to a temperature measurement and vacuum drying box temperature parameter calibration device. Background Art

[0002] The vacuum drying oven uses vacuum drying technology to place the material in a vacuum environment, lowering the boiling point of water. The moisture inside the material diffuses to the surface through the pressure difference, thereby drying the material at a lower temperature. It is widely used in research and application fields such as chemical pharmaceuticals, medical health, biochemistry, agricultural research, and environmental protection. It is used for powder drying, baking, and disinfection and sterilization of various glass containers.

[0003] Currently, most domestic metrology institutions calibrate vacuum drying oven temperature parameters using traditional calibration methods. This involves measuring the temperature field in the vacuum drying oven under normal pressure, rather than vacuum. Because convection heat transfer is severely weakened when the vacuum drying oven is near absolute vacuum, heat transfer relies primarily on conduction and radiation from the coils and chamber walls to the material. Without air as a medium, the heat transfer method changes. This results in uneven temperature distribution within the chamber, significant temperature fluctuations, and a long stabilization time. This can lead to significant measurement deviations and poor repeatability, making inconsistent results common across multiple calibrations.

[0004] The authorization announcement number is CN209197925U, and the name is a wireless surface temperature measuring device. The device includes a surface temperature sensor, a data collector, a controller, a power module, a storage medium, a wireless transmitting module, a wireless receiving module, a terminal and a packaging shell. The data collector, controller, power module, storage medium and wireless transmitting module are arranged inside the packaging shell, and the surface temperature sensor, wireless receiving module and terminal are arranged outside the packaging shell. The surface temperature sensor is electrically connected to the data collector through a wire. Since the surface temperature sensor is located outside the packaging shell, it is easy to be bumped during operation, causing the surface temperature sensor to deform and be damaged. The packaging shell includes a stainless steel shell and an insulating material wrapped inside the stainless steel shell. Although there is insulating material inside the shell, in actual use, when the temperature to be measured exceeds 125°C, the temperature inside the packaging shell is also high due to the high temperature to be measured, which in turn causes units such as the controller and power supply to be easily damaged.

[0005] The authorization announcement number is CN210268921U, and its name is a wireless automatic temperature detection device inside an environmental test equipment box. The device includes a signal acquisition transmitter, a signal receiver, and a computer. The signal acquisition transmitter includes a heat-insulating box and a first antenna and a temperature-sensitive element arranged on the heat-insulating box. The heat-insulating box is provided with modules such as data acquisition, first signal conversion, and first wireless. Since the temperature-sensitive element is a platinum resistance sensor fixed on the outer surface of the heat-insulating box, it measures the ambient temperature inside the box and cannot accurately measure the surface temperature of the object. The heat-insulating box includes an outer shell, an inner liner, a vacuum layer, and a cover. There is a silver coating on the inner wall of the inner liner. Due to the complex structure of the heat-insulating box, the production cost is relatively high. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present application and its application or use. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0033] Example 1:

[0034] like Figures 1 to 3As shown, the utility model discloses a temperature measuring device including a device containing bottle, a heat-insulating shell, a heat-conducting cover, a temperature sensing probe, a processor 4, a wireless communication unit 5 and a power supply unit (6), the device containing bottle including a first containing shell 1, a second containing shell 2 and a neck 3, the first containing shell 1 and the second containing shell 2 forming a bottle body, the first containing shell 1 and the second containing shell 2 being threadedly connected together or separated, the first containing shell 1 and the second containing shell 2 being threadedly connected together to form a cylindrical shell, the neck 3 being a round tube, the neck 3 being fixedly connected to the first containing shell 1, the inside of the connected first containing shell 1 and the second containing shell 2 forming a device containing cavity for containing the processor 4, the wireless communication unit 5 and the power supply unit 6, the device containing cavity being connected to the outside through the neck 3, the processor 4, the wireless communication unit 5 and the power supply unit 6 being located in the device containing cavity of the device containing bottle.

[0035] The device containing bottle is a shell made of polyetheretherketone (PEEK), and the wall thickness of the device containing bottle is about 1 mm. The shell made of polyetheretherketone (PEEK) is resistant to high temperatures, but the material is very expensive. If the device containing bottle is made thicker, the cost will be higher, which is not cost-effective.

[0036] Without an insulating outer shell, a device container with a wall thickness of approximately 1mm can withstand temperatures up to 125°C during actual temperature measurements. When the measured temperature does not exceed 125°C, the processor 4, wireless communication unit 5, and power supply unit 6 inside the device container function normally. However, if the measured temperature exceeds 125°C, the processor 4 and power supply unit 6 inside the device container will be damaged. While a shell made of polyetheretherketone (PEEK) offers excellent heat resistance, it still cannot solve the problem of damage to the processor 4 and power supply unit 6 inside the device container when the measured temperature exceeds 125°C.

[0037] like Figure 1 As shown, the thermal cover is a first thermal cover 7, which has a C-shaped longitudinal cross-section. The inner wall of the first thermal cover 7 is fixed with threads, and the first thermal cover 7 is threadedly connected to or separated from the neck 3. A receiving groove is defined on the inner top surface of the first thermal cover 7. The temperature sensor is a PT100 thin film resistor 8, which is fixed in the receiving groove. The distance between the bottom of the receiving groove and the outer surface of the top of the first thermal cover 7 is 1 mm.

[0038] The first heat-conducting cover 7 is a shell made of copper material. The top surface of the first heat-conducting cover 7 is the measuring end surface. The receiving groove is an embedded installation position. The temperature sensing probe is embedded in the receiving groove and can be placed as close to the measuring end surface as possible. The outer wall of the shell at the temperature sensing probe is relatively thin, about 1 mm, so that the time for heat conduction and perception by the temperature sensing probe is shortened, the perception is faster, and the temperature measurement is faster.

[0039] like Figure 2As shown, the processor 4 includes a data collector, a slave controller and a memory. The temperature sensor is connected to the data collector through a wire, the data collector is electrically connected to the slave controller, the slave controller is electrically connected to the memory, the slave controller is electrically connected to the wireless communication unit 5, and the power supply unit 6 is electrically connected to the slave controller.

[0040] like Figure 1 As shown, the thermal insulation shell includes a first thermal insulation shell and a second thermal insulation shell, the first thermal insulation shell includes a first stainless steel shell 9, a first thermal insulation cloth 10 and a first thermal insulation filler, a through hole is opened on the upper part of the first stainless steel shell 9, the first thermal insulation cloth 10 is fixedly connected to the inner side of the first stainless steel shell 9, a first filling cavity 11 for accommodating the first thermal insulation filler is formed between the first thermal insulation cloth 10 and the first stainless steel shell 9, the first thermal insulation filler is aerogel and fills the first filling cavity 11, a first bottle body accommodating cavity is formed between the first thermal insulation cloth 10 and the through hole on the upper part of the first stainless steel shell 9, one end of the first bottle body accommodating cavity is connected to the outside world through the through hole on the upper part of the first stainless steel shell 9, and the other end of the first bottle body accommodating cavity is connected to the outside world.

[0041] The second thermal insulation shell includes a second stainless steel shell 12, a second thermal insulation cloth 13 and a second thermal insulation filler. The second thermal insulation cloth 13 is fixedly connected to the inner side of the second stainless steel shell 12. A second filling cavity 14 for accommodating the second thermal insulation filler is formed between the second thermal insulation cloth 13 and the second stainless steel shell 12. The second thermal insulation filler is aerogel and fills the second filling cavity 14. The second thermal insulation cloth 13 forms a second bottle body accommodating cavity in the space on the other side of the second filling cavity 14. One end of the second bottle body accommodating cavity is connected to the outside world.

[0042] The first thermal insulation shell and the second thermal insulation shell are threadedly connected together or separated, and the first thermal insulation cloth 10 and the second thermal insulation cloth 13 are spliced ​​on the inner sides of the connected first thermal insulation shell and the second thermal insulation shell to form a bottle body accommodating cavity of the first accommodating shell 1 and the second accommodating shell 2 for accommodating the device accommodating bottle.

[0043] Among them, the temperature sensor, data collector, slave controller, memory, wireless communication unit 5 and power supply unit 6 themselves and the corresponding connection technology are existing technologies and are not described in detail here.

[0044] Instructions for use of the first mode temperature measuring device:

[0045] like Figure 3As shown, the first containing shell 1, the second containing shell 2 and the neck 3, the first heat-conducting cover 7, the thin film resistor 8, the processor 4, the wireless communication unit 5 and the power supply unit 6 of the device containing bottle form a first mode temperature measuring device. When the first mode temperature measuring device is used to measure the temperature, when the temperature to be measured does not exceed 125°C, the electronic device in the device containing cavity of the device containing bottle can still work normally, and it is flexible and convenient to use.

[0046] The heat-insulating shell is detachable. When the temperature to be measured does not exceed 125°C, the heat-insulating shell is not used.

[0047] Instructions for use of the second mode temperature measuring device:

[0048] like Figure 1 As shown, the first containing shell 1, the second containing shell 2 and the neck 3 of the device containing bottle, the first stainless steel shell 9 of the heat-insulating shell, the first heat-insulating cloth 10, the first filling cavity 11, the second stainless steel shell 12, the second heat-insulating cloth 13 and the second filling cavity 14, the first heat-conducting cover 7, the thin-film resistor 8, the processor 4, the wireless communication unit 5 and the power supply unit 6 form a second mode temperature measuring device. The second mode temperature measuring device is used for temperature measurement. When the temperature to be measured exceeds 125°C, a detachable heat-insulating shell is added to the outside of the first containing shell 1 and the second containing shell 2 of the device containing bottle, so that the electronic devices in the device containing cavity of the device containing bottle can work normally and can withstand the temperature to be measured of 200°C.

[0049] During use, the first insulation shell and the second insulation shell are rotated and unscrewed to separate them, and the neck 3 of the device container bottle is inserted from the lower part of the first bottle body accommodating cavity of the first insulation shell and then passed upward through the through hole in the upper part of the first stainless steel shell 9, so that the upper part of the device container bottle, i.e., the upper part of the first container shell 1, is located in the first bottle body accommodating cavity. The second insulation shell is covered with the lower part of the device container bottle, i.e., the lower part of the second container shell 2, and the first stainless steel shell 9 of the first insulation shell and the second stainless steel shell 12 of the second insulation shell are rotated and tightened to connect them together. At this time, the first container shell 1 and the second container shell 2 of the device container bottle are located in the bottle body accommodating cavity formed by the first insulation cloth 10 of the first insulation shell and the second insulation cloth 13 of the second insulation shell. Since the first filling cavity 11 and the second filling cavity 14 are filled with aerogel, and the aerogel and the insulation cloth are both made of relatively soft materials, the first insulation cloth 10 and the second insulation cloth 13 can wrap the first container shell 1 and the second container shell 2 of the device container bottle.

[0050] Example 2:

[0051] The utility model discloses a device for calibrating temperature parameters of a vacuum drying oven, which comprises the temperature measuring device described in embodiment 1, a controller and a host computer.

[0052] like Figure 4 As shown, the controller includes a physical interface, a main controller, a wireless protocol controller and a radio frequency transceiver unit. The main controller is electrically connected to and communicates with the physical interface, the main controller is electrically connected to and communicates with the wireless protocol controller, the wireless protocol controller is electrically connected to and communicates with the radio frequency transceiver unit, and the host computer is electrically connected to and communicates with the physical interface.

[0053] The temperature measuring device described in Example 1 is a wireless measurement node, and the wireless communication unit 5 in the wireless measurement node is wirelessly connected to and communicates with the radio frequency transceiver unit.

[0054] The thermal cover in the wireless measurement node is made of copper. Its high density and excellent thermal conductivity allow it to meet the weight gain requirements of the gravity device while also enabling rapid temperature measurement. During measurement, the temperature probe maintains close contact with the inner wall of the receiving groove on the top surface of the thermal cover and is as close to the measured surface as possible, minimizing measurement errors and response time. Based on the temperature sensor's measurement principle and dimensions, a recessed mounting location, or receiving groove, is designed on the bottom layer of the thermal cover. The temperature probe is positioned as close as possible to the measurement end face, or the top surface of the thermal cover. The outer wall of the thermal cover is thinner at the temperature-sensing portion of the probe, providing excellent thermal conductivity and enabling rapid temperature measurement.

[0055] The working process of Example 2 is described as follows:

[0056] The wireless measurement node is usually in a low-power sleep state. After receiving measurement information, it wakes up at a set time interval to start the measurement function, and saves the measured data to the memory or sends it wirelessly to the controller in real time. It re-enters sleep after the test is completed; the controller is responsible for externally activating the wireless measurement node and wirelessly sending the set measurement information to the wireless measurement node. The measurement information includes the test interval, test duration, whether it is sent in real time, and the test start delay time, etc. The received information from the wireless measurement node is transmitted to the host computer, assuming the control and coordination function; the host computer performs human-computer interaction and is responsible for the automatic acquisition and processing of programmed and process-based calibration data.

[0057] It is used to calibrate the temperature parameters of a vacuum drying oven. It can accurately measure the temperature of the heating plate layer inside the vacuum drying oven when the vacuum drying oven is completely sealed and the box is close to vacuum negative pressure. It is a relatively economical and simple vacuum drying oven temperature parameter calibration device.

[0058] Example 3:

[0059] The difference between Example 3 and Example 1 lies in the structure of the heat-conducting cover.

[0060] The utility model discloses a temperature measuring device including a device containing bottle, a heat-insulating shell, a heat-conducting cover, a temperature sensing probe, a processor 4, a wireless communication unit 5 and a power supply unit 6, and the similarities are not repeated here.

[0061] like Figure 5 As shown, the thermal cover is a second thermal cover 15, which has a π-shaped longitudinal cross-section. The outer wall of the second thermal cover 15 is fixed with threads, and the second thermal cover 15 is threadedly connected to or separated from the inner wall of the neck 3. A receiving groove is defined on the inner top surface of the second thermal cover 15 for securing the temperature sensor. The distance between the bottom of the receiving groove and the outer surface of the top of the second thermal cover 15 is 1 mm.

[0062] The second heat-conducting cover 15 is a shell made of copper material. The top surface of the second heat-conducting cover 15 is the measuring end surface. The receiving groove is an embedded installation position. The temperature sensing probe is embedded in the receiving groove and can be placed as close to the measuring end surface as possible. The outer wall of the shell at the temperature sensing probe is relatively thin, about 1 mm, so that the time for heat conduction and sensing by the temperature sensing probe is shortened, sensing is faster, and temperature measurement is faster.

[0063] Example 4:

[0064] The utility model discloses a temperature measuring device including a device accommodating bottle, a heat-insulating shell, a heat-conducting cover, a temperature sensing probe, a processor 4 and a wireless communication unit 5. The device accommodating bottle includes a bottle body for accommodating the processor 4 and the wireless communication unit 5 and a neck 3 fixedly connected to the bottle body. The interior of the bottle body is connected to the outside through the neck 3, and the heat-conducting cover is threadedly connected to the neck 3; the processor 4 is electrically connected to the temperature sensing probe and the wireless communication unit 5 respectively, and a accommodating groove is provided on the inner top surface of the heat-conducting cover, and the temperature sensing probe is fixedly connected in the accommodating groove; the heat-insulating shell includes a first heat-insulating shell and a second heat-insulating shell, the first heat-insulating shell and the second heat-insulating shell are connected together or separated, and a bottle body accommodating cavity for accommodating the bottle body is formed on the inner sides of the connected first heat-insulating shell and the second heat-insulating shell, and the similarities are not repeated here.

[0065] Example 4 differs from Example 1 in that the device-holding bottle is integrally formed, i.e., the bottle body and neck 3 are integral. The first thermal insulation shell includes a first support shell, a first thermal insulation sheet, and a first thermal insulation filler. The second thermal insulation shell includes a second support shell, a second thermal insulation sheet, and a second thermal insulation filler. The first thermal insulation sheet and the second thermal insulation sheet are both made of hard insulating materials. The similarities are not repeated here.

[0066] Before measurement, the heat-conducting cover is opened, and the power supply unit 6 is installed from the open end of the neck 3. The processor 4 is electrically connected to the power supply unit 6, and the power supply unit 6 is located in the bottle body of the device receiving bottle.

[0067] The one-piece device container is simpler to manufacture and less expensive. The diameter of the neck is larger than the size of the electronic device to be housed, making it easier to assemble. This makes it difficult to load the electronic device into the container.

[0068] Since the heat insulation sheet is made of a hard heat insulation material, the fit between the heat insulation sheet and the bottle body of the device receiving bottle will be reduced, but it will not affect the heat insulation effect.

[0069] Compared with the above embodiment, it is also possible to adopt: the first supporting shell of the first heat-insulating shell is clipped or plugged with the second supporting shell of the second heat-insulating shell, which is also more convenient to use.

[0070] Compared with the above embodiment, it is also possible to adopt: the distance between the bottom surface of the receiving groove and the outer surface of the top surface of the heat conductive cover is 0.9 mm, and the wall thickness of the device receiving bottle is 0.9 mm, which can also meet the technical requirements for the normal operation of electronic devices.

[0071] Compared with the above embodiment, it is also possible to adopt: the heat-conducting cover is clipped or plugged with the neck 3, which is also more convenient to use.

[0072] Compared with the above embodiment, it is also possible to adopt the following method: the first accommodating shell 1 and the second accommodating shell 2 are snap-fitted or plugged together, which is also more convenient to use.
