[0003] Since some microorganisms have strict temperature requirements for survival, it is necessary to ensure that the temperature is suitable during the rotation and vibration process in order to achieve the desired effect.
[0004] Currently, while existing vortex oscillators can achieve the effect of ensuring a suitable internal temperature of the apparatus, in actual use, the heating instruments that ensure the internal temperature of the apparatus are mostly located on the outside of the apparatus. During the vibration and rotation of the test tube, the surrounding airflow will rotate, thereby changing the temperature around it and affecting the experimental data. Therefore, the experimental error is relatively large for test tubes located in the middle after rotation and vibration. To address this issue, a vortex oscillator that is easy to control in temperature is proposed. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0036] Reference Figure 1 - Figure 3 The present invention provides an embodiment of a temperature-controlled vortex oscillator, comprising a body 1, which is a vortex oscillator with a groove inside for placing test tubes. When the device is started, the test tubes in the groove can rotate and vibrate. This technology is prior art and can be implemented by those skilled in the art, so it will not be described in detail here. The top of the body 1 is fitted with a cover 2, which is colorless and transparent, and the cover 2 and the body 1 can be separated from each other.
[0037] Reference Figure 3 , Figure 4 and Figure 6 The body 1 is equipped with a temperature control mechanism 3. The temperature control mechanism 3 includes a mounting slot 31, which is located below the groove in the body 1 for storing test tubes. The mounting slot 31 is located inside the body 1. A fan 32 is fixedly connected to the inner wall of the mounting slot 31. The airflow of the fan 32 is upward. A heating wire 33 is fixedly connected to the inner wall of the mounting slot 31. The heating wire 33 can emit a high temperature to achieve a heating effect. A heating wire 34 is fixedly connected to the inside of the mounting slot 31. The heating wire 34 can emit a specified temperature to achieve a heat preservation effect. A movable frame 35 is slidably connected to the inner wall of the mounting slot 31.
[0038] Reference Figure 3 , Figure 8 and Figure 9 A moving component 310 is provided on the outside of the moving frame 35 and inside the body 1. The moving component 310 includes a rack 311. The outer wall of the rack 311 is fixedly connected to the outer wall of the moving frame 35. A rotating bar 312 passes through the inner wall of the body 1. A gear 313 is slidably connected to the outer wall of the rotating bar 312. By sliding the connection, it is ensured that the rotating bar 312 can drive the gear 313 to rotate synchronously with it when it rotates. The gear 313 meshes with the rack 311. An insert 314 is fixedly connected to the front end of the rotating bar 312. The outer wall of the insert 314 is provided with multiple protrusions. An insertion hole 315 is opened on the inner wall of the body 1. The shape of the insertion hole 315 matches the shape of the insert 314. By inserting the insert 314 into the insertion hole 315, the rotating bar 312 can be prevented from rotating.
[0039] Reference Figure 3 , Figure 5 and Figure 6 The bottom of the movable frame 35 is provided with an air inlet 36, which allows hot air to enter the interior of the movable frame 35. The top of the movable frame 35 is fixedly connected with a diverter pipe 37, which allows hot air to be distributed to the periphery of each test tube inside the body 1. The inner wall of the diverter pipe 37 is provided with an air outlet 38, and the inner wall of each diverter pipe 37 is provided with multiple air outlets 38, which are arranged in a linear array in the vertical direction. The orientation of the air outlets 38 corresponds to the orientation of the grooves for placing test tubes inside the body 1.
[0040] Reference Figure 3 , Figure 6 and Figure 7 The installation slot 31 is also equipped with a temperature control component 39, which includes a pressure pipe 391. The inner wall of the pressure pipe 391 is connected to a piston plate 392. The pressure pipe 391 is filled with gas below the piston plate 392. The gas has the property of thermal expansion. The top of the piston plate 392 is fixedly connected to a push rod 393. The inner wall of the installation slot 31 above the push rod 393 is fixedly connected to an installation plate 394. The bottom of the installation plate 394 is equipped with a switch for heating wire 1 33. When the push rod 393 presses the switch, heating wire 1 33 is in the off state. Otherwise, when heating wire 2 34 is started, heating wire 1 33 is started. That is, heating wire 1 33 and heating wire 2 34 are in parallel. The switch is in the branch circuit of heating wire 1 33. There is another switch in the main circuit to control the start and stop of heating wire 1 33 and heating wire 2 34.
[0041] Reference Figure 1 - Figure 3 The machine body 1 is equipped with a dust-blocking component 4. The dust-blocking component 4 includes a moving groove 41. A sliding plate 42 is slidably connected to the inner wall of the moving groove 41. There is friction between the outer wall of the sliding plate 42 and the inner wall of the moving groove 41, which can form a damping effect. A connecting hole 43 is opened on the inner wall of the sliding plate 42. The distance between two connecting holes 43 is greater than the diameter of a single connecting hole 43. A control strip 44 is fixedly connected to the outer wall of the sliding plate 42. The control strip 44 passes through and is slidably connected to the inner wall of the machine body 1. Through the setting of the control strip 44, the operator can control the left and right movement of the sliding plate 42.
[0042] Working principle: When in use, the staff places the test tube containing the microorganisms that need to be rotated and vibrated into the groove of the machine body 1, then closes the machine cover 2 and turns on the power of the equipment.
[0043] When the device is powered on, heating wire 33, heating wire 34 and fan 32 are all started. At this time, because heating wire 33 has a higher temperature, it can heat up quickly.
[0044] When the temperature is sufficient, the gas inside the pressure pipe 391 expands due to heat, pushing the piston plate 392 upward. This causes the piston plate 392 to drive the push rod 393 upward, thereby touching the switch of the control heating wire 33 and turning it off. At this time, the heating wire 33 is still in the start-up state, so the temperature can be maintained at the specified state.
[0045] Since the fan 32 is on, the hot air can generate an upward force. Therefore, the hot air can first enter the interior of the moving frame 35 through the air inlet 36, then enter the diversion pipe 37, and finally be discharged through the air outlet 38. Since the diversion pipe 37 is located outside the area where the test tube is located, the hot air discharged through the air outlet 38 can directly contact the test tube, so it is not easily affected by the external airflow, thus ensuring the stability of the external temperature of the test tube.
[0046] After use, the staff removes the test tube and rotates the rotating bar 312 while pulling it outward.
[0047] Since the rotating bar 312 can be pulled outward to make the insert 314 leave the insertion hole 315, the rotating bar 312 can rotate normally. While rotating, the rotating bar 312 can drive the gear 313 to rotate, thereby causing the rack 311 to move downward through the rotation of the gear 313, which in turn causes the moving frame 35 to move downward, thereby causing the diversion tube 37 to retract to the inner position of the body 1.
[0048] When the diverter tube 37 moves to the lowest position, the staff pushes the control bar 44, and the casing causes the slide plate 42 to slide, thereby blocking the hole opened in the body 1. Therefore, when the equipment is not in use, the diverter tube 37 can be well protected and is not easily broken due to the cover 2 falling off and being subjected to force when the equipment is dropped.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
