Description

Technical Field

[0001] This utility model belongs to the technical field of nucleic acid extraction equipment, specifically relating to a temperature measuring device for nucleic acid extraction equipment. Background Technology

[0002] Nucleic acid extraction equipment is a key piece of equipment in modern biotechnology, capable of efficiently and accurately extracting pure nucleic acids from complex biological samples. It is widely used in life sciences, medical diagnostics, and environmental monitoring. Its working principle is based on advanced biochemical technology, featuring high efficiency, low error rate, and good reproducibility, and can process various sample types.

[0003] Existing nucleic acid extraction equipment uses temperature measurement devices with temperature sensors embedded in a plate structure. For example, in an eight-row heating port setup, only four temperature probes are used, resulting in a limited number of samples that can be analyzed. During operation, most nucleic acid extraction devices cannot control the position of the magnetic rods and their holders. The existing temperature measurement devices are large, making it easy for the temperature probes to collide with the magnetic rods during measurement, causing damage to both. Furthermore, existing temperature measurement devices require external data processing equipment, which powers them, making them inconvenient to use. Utility Model Content

[0028] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] Example

[0030] Please refer to the reference. Figures 1 to 5As shown, this embodiment provides a temperature measuring device for nucleic acid extraction equipment, including a display screen 1, a control module 2, a data acquisition module 3, a power supply module 4, and a temperature probe. The control module 2 is connected to the display screen 1 and the data acquisition module 3, and the power supply module 4 is connected to the data acquisition module 3. The data acquisition module 3 is provided with multiple sets of outwardly extending high-temperature wire groups 5, and each set of high-temperature wire groups 5 is connected to the temperature probe.

[0031] Specifically, the acquisition module 3 acquires temperature data measured by the temperature probe and transmits the temperature data to the control module 2. The temperature data is then processed by the control module 2 and displayed on the display screen 1. The control module 2 has a processing chip on its circuit board, specifically an STMicroelectronics STM32F103RET6, used to process the data transmitted by the acquisition module. The acquisition module 3 has an acquisition chip on its circuit board, specifically a Texas Instruments ADS1278. The power module 4 includes a battery that continuously powers the display screen 1, control module 2, acquisition module 3, and temperature probe. The control module 2, acquisition module 3, and power module 4 can all utilize existing technologies. The acquisition module 3 has twelve sets of high-temperature wire groups 5, each group containing two high-temperature wires. These high-temperature wires are heat-resistant conductors and connect the acquisition module 3 to the temperature probe.

[0032] In this embodiment, the temperature probe includes a temperature sensor 7 and a temperature sensor protection component 6. The wires of the temperature sensor 7 are connected to the high-temperature wire group 5, and the temperature sensor protection component 6 is sleeved on the temperature sensor 7.

[0033] Specifically, the temperature sensor protective element 6 is made of a metal material, such as copper, which has good thermal conductivity and strength. The temperature sensor protective element 6 is cylindrical in shape, and the temperature sensor 7 is inserted into the temperature sensor protective element 6.

[0034] In this embodiment, the temperature sensor protective component 6 is provided with a spherical crown 601, a conical part 602, a cylindrical part 603 and an annular boss part 604 from head to tail. The spherical crown 601 can better protect the detection end of the temperature sensor 7, and the annular boss part 604 can be more firmly connected to the heat shrink tubing.

[0035] The temperature sensor 7 includes a spherical thermistor with a protective layer. Two wires are connected to the rear of the spherical thermistor. When the temperature sensor 7 is inserted into the temperature sensor protection component 6, the spherical thermistor at the front is located inside the spherical crown, and the wires at the rear are connected to the high-temperature wire in the high-temperature wire 5. The two can be connected by welding.

[0036] In this embodiment, a first heat shrink tubing 8 is sleeved on the connection area between the wire of the temperature sensor 7 and the high-temperature wire group 5.

[0037] Specifically, the first heat shrink tubing 8 is fixed to the connection area between the wire of the temperature sensor 7 and the high-temperature wire group 5 by heating, which can prevent the high-temperature wire group 5 from falling off the temperature sensor 7.

[0038] In this embodiment, a silicone tube 9 is fitted around the tail of the temperature sensor protection component 6, the first heat shrink tubing 8, and the high-temperature wire assembly 5.

[0039] Specifically, covering the tail of the temperature sensor protective component 6, the first heat shrink tubing 8, and the entire high-temperature wire assembly 5 with silicone tubing 9 can better protect the tail of the temperature sensor protective component 6, the first heat shrink tubing 8, and the high-temperature wire, further integrating the temperature sensor protective component 6 with the first heat shrink tubing 8 and the high-temperature wire, and preventing the high-temperature wire from detaching from the temperature sensor 7.

[0040] In this embodiment, a second heat-shrink tubing 10 is fitted over the silicone tube 9.

[0041] Specifically, the silicone tube 9 is covered by the second heat shrink tubing 10, which further secures the silicone tube 9, thereby making the connection between the high-temperature wire and the temperature sensor 7 more robust.

[0042] In this embodiment, the temperature probe is 7 mm long, which is well-suited for most types of nucleic acid extraction equipment.

[0043] In this example, the temperature measurement device for nucleic acid extraction equipment involves placing each temperature probe in a small piece of thermally conductive clay and then placing it on the surface of the test channel of the nucleic acid extraction equipment to measure the temperature. The measured temperature data is then directly displayed on the display screen 1. The device has multiple temperature probes and is easy to use.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
