Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] Refer to the attached Figure 1-5 The utility model provides a wireless centrifuge temperature detection device, comprising the following structure:

[0037] The rotor 1 has a frame 11 fixedly disposed at the bottom thereof, a motor 12 is clamped in the middle of the bottom surface of the frame 11, a plurality of assembly holes 13 are fixedly disposed at equal intervals on the surface of the rotor 1, a test tube 14 is inserted into the assembly hole 13, and a Bluetooth temperature sensor 2 is inserted in the middle of the test tube 14.

[0038] The gas cylinder 3 has an expansion ring 4 fixedly disposed on the top thereof, a guide tube 5 fixedly disposed on the bottom thereof, and a guide rod 6 movably sleeved on the middle portion of the guide tube 5.

[0039] In this embodiment, Figure 3 As shown, a connecting seat 21 is fixedly provided at the bottom of the Bluetooth temperature sensor 2 , and the bottom of the connecting seat 21 is threadedly connected to the middle of the gas cylinder 3 .

[0040] In the temperature detection operation of a centrifuge with temperature regulation functions such as refrigeration, it is necessary to place the wireless temperature Bluetooth temperature sensor 2 in the test tube 14, and then place the test tube 14 on the assembly hole 13 of the rotor 1. The motor 12 drives the rotor 1 to rotate through the frame 11 to simulate the actual operating state of the centrifuge. Due to the high-speed rotation of the rotor 1, it is impossible to use traditional wired thermocouples such as PT100, etc., and it is necessary to use the Bluetooth temperature sensor 2 in conjunction with the temperature patrol meter to perform the temperature detection operation of the centrifuge.

[0041] In this embodiment, Figure 3 and Figure 4 As shown, the top of the gas cylinder 3 is movably connected to the bottom of the Bluetooth temperature sensor 2 , and an air chamber 31 is fixedly provided on the inner side of the gas cylinder 3 , and the air chamber 31 extends to the inner side of the expansion ring 4 .

[0042] As the air pressure in the air chamber 31 in the air cylinder 3 increases, the expansion ring 4 deforms and begins to expand, so that the outer portion of the expansion ring 4 contacts the inner wall of the test tube 14 , thereby completing the stable clamping of the Bluetooth temperature sensor 2 in the test tube 14 .

[0043] In this embodiment, Figure 3 , Figure 4 and Figure 5 As shown, a compression chamber 51 is fixedly provided in the middle of the guide tube 5 , the compression chamber 51 is communicated with the air chamber 31 , the top air outlet of the guide tube 5 extends into the air chamber 31 , and a return spring 52 is clamped at the bottom of the guide tube 5 .

[0044] The compression chamber 51 in the guide tube 5 provides guidance for the movement of the sealing plug 61 , and the reset spring 52 is configured to push and move away from the air cylinder 3 through the bottom plate 63 .

[0045] In this embodiment, Figure 3 and Figure 5As shown, a sealing plug 61 is fixedly provided on the top of the guide rod 6 , and the sealing plug 61 extends into the compression chamber 51 . A sealing ring 62 is fixedly provided on the outer side of the sealing plug 61 , and the outer side of the sealing ring 62 is movably connected to the inner wall of the guide tube 5 .

[0046] The cooperation between the sealing ring 62 and the sealing plug 61 improves the sealing performance of the assembly between the sealing plug 61 and the guide tube 5. During the high-speed rotation of the rotor 1, the guide rod 6 and the guide tube 5 are movably connected, and the Bluetooth temperature sensor 2 moves toward the bottom of the test tube 14. The bottom plate 63 contacts the bottom of the inner wall of the test tube 14, completing the movement of the sealing plug 61 toward the top of the guide tube 5, and compressing the air in the compression chamber 51 into the air chamber 31, completing the expansion of the expansion ring 4, avoiding the Bluetooth temperature sensor 2 from shaking in the test tube 14, and improving the safety of the temperature detection operation of the centrifuge.

[0047] In this embodiment, Figure 3 and Figure 5 As shown, a bottom plate 63 is fixedly provided at the bottom of the guide rod 6 , the top of the bottom plate 63 is engaged with the bottom of the return spring 52 , and the bottom of the bottom plate 63 is in contact with the inner wall of the test tube 14 .

[0048] After the rotor 1 stops working, the return spring 52 works to push the guide tube 5 toward the mouth of the test tube 14. At this time, the sealing plug 61 moves toward the bottom of the guide tube 5, and the expansion ring 4 begins to shrink, which is convenient for the user to extract the Bluetooth temperature sensor 2 from the test tube 14 and to facilitate the user to clamp the Bluetooth temperature sensor 2 during the temperature detection operation of the centrifuge.

[0049] The above-described embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the patent of the utility model shall be based on the attached claims.
