Technical Field
[0001] The utility model belongs to the technical field of a thermometer capable of automatic calibration, and more specifically, particularly relates to a thermometer capable of automatic calibration. Background Art
[0002] As a commonly used tool for measuring human body temperature in current life, after long-term use, due to objective reasons such as the aging of internal circuit components of the electronic thermometer, the measurement accuracy of the electronic thermometer will decrease. Once the accuracy of the electronic thermometer decreases, this decreasing process is irreversible, and it is difficult for users to correct the measurement accuracy of the electronic thermometer, thus affecting the use of the electronic thermometer.
[0003] Based on the above, the inventor found the following problems: The current calibration method of the electronic thermometer is generally to place one or more groups of electronic thermometers and an accurate thermometer under the same constant temperature condition for comparison, and then manually adjust the inaccurate thermometer. However, even in the same temperature environment, there will be slight temperature differences at different temperature measurement points, and manual calibration will move the thermometer, resulting in the thermometer being separated from the temperature measurement position, and thus the calibration of the thermometer is inaccurate.
[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a thermometer capable of automatic calibration is provided, in order to achieve the purpose of having more practical value. Content of the Utility Model
[0005] The purpose and effect of the thermometer capable of automatic calibration of the utility model are achieved by the following specific technical means:
[0006] The thermometer capable of automatic calibration includes a main body, a display screen, a contact probe, and a remote server. A wireless unit, a temperature measurement unit, a control unit, and a display screen unit are provided inside the main body. A display screen is provided on the outer surface of the main body, and the display screen is connected to the control unit. A contact probe is provided at one end of the main body, and the contact probe is connected to the temperature measurement unit. A connection component is provided on the contact probe.
[0007] Furthermore, a wireless transmission section, a control section, and a data processing unit are provided inside the remote server.
[0008] Further, the connection component includes a rotary handle, a contraction piece, a kit, a base, a connecting rod, an adapter plate and a connecting column. One end of the connecting rod is provided with a first through hole, and the base is fixedly arranged at the bottom end of the first through hole. One end of the contraction piece is fixedly arranged on the base. The top of the contraction piece is designed as an inclined surface. A second through hole is arranged inside the contraction piece, and a thread groove is arranged on the inner wall of the top end of the first through hole. A third through hole is arranged inside the kit. A first thread is arranged on the outer side of the kit, and the first thread is matched with the thread groove. A rotary handle is arranged at one end of the kit. The end of the third through hole away from the rotary handle is designed as an inclined surface, and a fourth through hole is arranged inside the rotary handle.
[0009] Further, a second thread is arranged at the other end of the connecting rod. A plurality of threaded holes are arranged on the side surface of the adapter plate. The second thread is matched with the threaded holes. A connecting column is arranged at one end of the adapter plate.
[0010] Further, the wireless transmission module on the remote server can be connected to or transmit data to the wireless units on multiple groups of thermometers.
[0011] Further, the inside of the connection component is made of copper material with good heat conduction effect, and the surface of the connection component is coated with a heat insulation layer.
[0012] Further, the second through hole, the third through hole and the fourth through hole have the same diameter, and the diameter of the second through hole is larger than the diameter of the contact probe.
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] In the utility model, by moving the thermometer, the contact probe is driven to move into the connecting rod. At this time, the contact probe sequentially passes through the fourth through hole, the third through hole and the second through hole and contacts the base. Then, the rotary handle is rotated to drive the kit to rotate. Under the action of the first thread and the thread groove, the kit moves towards the inside of the first through hole. At the same time, the inclined surface end of the kit presses the top inclined surface position of the contraction piece, so that the contraction piece contracts and fits on the surface of the contact probe. As the kit continues to move towards the inside of the first through hole, the effect of fixing the contact probe and the connecting rod is achieved, so that the contact probe can measure the temperature through the connection component;
[0015] Through the design of the connecting rod, the second thread and the threaded holes, the adapter plate can be connected to multiple groups of thermometers, so that multiple groups of thermometers can be calibrated together;
[0016] By wirelessly connecting to a thermometer through a remote server, data in the temperature measurement unit of a thermometer with accurate measurements and data in the temperature measurement unit of a thermometer with inaccurate measurements can be received into the data processing unit for data processing. When a calibration command is issued on the control panel of the remote server, the data processing unit accepts the command. Then, the remote server transmits the measurement data of the thermometer with accurate measurements to the control unit in the thermometer with inaccurate measurements through the wireless transmission module. The control unit in the thermometer with inaccurate measurements then transmits the data to the internal display unit, thereby changing the displayed temperature data on the display screen to accurate measurement data. By wirelessly controlling the calibration of the thermometer through the remote server, direct contact with the thermometer can be avoided, preventing it from moving out of the measurement environment and reducing the influence of external factors on the calibration effect, thus improving the accuracy of thermometer calibration;
[0017] Since the inside of the connection component is made of copper material with good heat conduction effect and is designed with a heat insulation layer on the surface, while quickly transmitting the temperature at the measurement point, it also avoids the influence of the external environmental temperature on the transmitted temperature inside the connection component, improving the unity of temperature measurement of multiple thermometers and ensuring the accuracy of subsequent thermometer calibration.

[0027] Embodiment:
[0028] As shown in the attached Figure 1 to the attached Figure 4 figures:
[0029] The present utility model provides a thermometer that can be automatically calibrated, including a main body 1, a display screen 2, a contact probe 3, and a remote server 9, characterized in that: a wireless unit, a temperature measurement unit, a control unit, and a display screen unit are provided inside the main body 1; a display screen 2 is provided on the outer surface of the main body 1, and the display screen 2 is connected to the control unit; a contact probe 3 is provided at one end of the main body 1, and the contact probe 3 is connected to the temperature measurement unit; and a connection component 8 is provided on the contact probe 3.
[0030] Among them, a wireless transmission board, a control board, and a data processing unit are provided inside the remote server 9.
[0031] Among them, the connection component 8 includes a rotating handle 801, a contraction member 802, a sleeve 803, a base 804, a connecting rod 805, an adapter plate 813 and a connecting column 814. One end of the connecting rod 805 is provided with a first through hole 806, and the base 804 is fixedly arranged at the bottom end of the first through hole 806. One end of the contraction member 802 is fixedly arranged on the base 804. The top of the contraction member 802 is designed as an inclined surface. A second through hole 807 is arranged inside the contraction member 802, and a thread groove 808 is arranged on the inner wall of the top end of the first through hole 806. A third through hole 809 is arranged inside the sleeve 803. A first thread 810 is arranged on the outer side of the sleeve 803, and the first thread 810 is matched with the thread groove 808. One end of the sleeve 803 is provided with a rotating handle 801. The third through hole 809 is designed as an inclined surface away from the rotating handle 801, and a fourth through hole 811 is arranged inside the rotating handle 801;
[0032] By moving the thermometer, the contact probe 3 is driven to move into the connecting rod 805. At this time, the contact probe 3 sequentially passes through the fourth through hole 811, the third through hole 809 and the second through hole 807 to contact the base 804. Then, the rotating handle 801 is rotated to drive the sleeve 803 to rotate. Under the action of the first thread 810 and the thread groove 808, the sleeve 803 moves in the direction of the first through hole 806. At the same time, the inclined surface end of the sleeve 803 presses the top inclined surface position of the contraction member 802, so that the contraction member 802 contracts and fits on the surface of the contact probe 3. As the sleeve 803 continuously moves in the direction of the first through hole 806, the effect of fixing the contact probe 3 and the connecting rod 805 is achieved, so that the contact probe 3 can measure the temperature through the connection component 8.
[0033] Among them, a second thread 812 is arranged at the other end of the connecting rod 805. A plurality of threaded holes 815 are arranged on the side surface of the adapter plate 813. The second thread 812 is matched with the threaded holes 815. One end of the adapter plate 813 is provided with a connecting column 814;
[0034] Through the design of the connecting rod 805, the second thread 812 and the threaded holes 815, the adapter plate 813 can be connected with multiple thermometers, so that multiple thermometers can be calibrated together.
[0035] Among them, the wireless transmission section on the remote server 9 can be connected to or transmit data with the wireless units on multiple groups of thermometers; by wirelessly connecting the remote server 9 with the thermometers, the data in the temperature measurement units of the thermometers with accurate measurements and the data in the temperature measurement units of the thermometers with inaccurate measurements can be received and processed in the data processing unit. When the control section on the remote server issues a calibration command, the data processing unit accepts the command, and then the remote server 9 transmits the measurement data of the thermometer with accurate measurements to the control unit in the thermometer with inaccurate measurements through the wireless transmission section. The control unit in the thermometer with inaccurate measurements then transmits the data to the internal display unit, so that the displayed temperature data on the display screen is changed to the accurate measurement data. By wirelessly controlling the calibration of the thermometer through the remote server, direct contact with the thermometer to move it out of the measurement environment can be avoided, reducing the influence of external factors on the calibration effect, thereby improving the accuracy of thermometer calibration.
[0036] Among them, the inside of the connection component 8 is made of copper material with good heat conduction effect, and the surface of the connection component 8 is coated with a heat insulation layer; through the design that the inside of the connection component 8 is made of copper material with good heat conduction effect and the surface is coated with a heat insulation layer, while quickly transmitting the temperature of the measurement point, the influence of the external environmental temperature on the transmitted temperature in the connection component 8 can also be avoided, improving the unity of the temperature measurements of multiple groups of thermometers and ensuring the accuracy of subsequent thermometer calibration.
[0037] Among them, the through holes 807, 809, and 811 have the same diameter, and the diameter of the through hole 807 is larger than the diameter of the contact probe 3; through the design of the through holes 807, 809, and 811, the contact probe 3 can extend into the connecting rod 805.
[0038] The specific usage method and function of this embodiment:
[0039] When using this device, first check the integrity of this device. First, move the inaccurate thermometer and the accurate thermometer towards the connecting rod 805, driving the contact probe 3 to move into the connecting rod 805. At this time, the contact probe 3 passes through the through hole four 811, the through hole three 809, and the through hole two 807 in sequence and contacts the base 804. Then rotate the rotating handle 801 to drive the kit 803 to rotate. Under the action of the thread one 810 and the thread groove 808, the kit 803 moves towards the inside of the through hole one 806. At the same time, the inclined surface end of the kit 803 squeezes the top inclined surface position of the shrinkage part 802, so that the shrinkage part 802 shrinks and fits on the surface of the contact probe 3. As the kit 803 continues to move towards the inside of the through hole one 806, the effect of fixing the contact probe 3 and the connecting rod 805 is achieved. Secondly, place the connecting column 814 on any object to be measured for temperature. At the same time, wirelessly connect to the thermometer through the remote server 9, and the data in the temperature measurement unit of the accurate thermometer and the data in the temperature measurement unit of the inaccurate thermometer can be received and processed in the data processing unit. Then, a calibration command is issued on the control board of the remote server 9, and the data processing unit accepts the command. Then, the remote server 9 transmits the measurement data of the accurate thermometer to the control unit in the inaccurate thermometer through the wireless transmission board. The control unit in the inaccurate thermometer then transmits the data to the internal display unit, so that the displayed temperature data on the display screen is changed to the accurate measurement data. Thus, the calibration of the thermometer is achieved. By wirelessly controlling the calibration of the thermometer through the remote server, direct contact with the thermometer to move it out of the measurement environment can be avoided, reducing the influence of external factors on the calibration effect, thereby improving the accuracy of thermometer calibration.
