Detailed Description
In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.
The utility model provides an ultrasonic blending device, which comprises a vibration device 1 and a driving device 2 for driving the vibration device 1 to move up and down, wherein the vibration device 1 comprises piezoelectric ceramics 1-1 connected with the driving device 2 in a driving way and a vibration rod 1-2 connected with the piezoelectric ceramics, and the vibration rod 1-2 can be contacted with the upper end surface of a reaction cup 4.
When the ultrasonic blending device disclosed by the utility model is used for blending the solution in the reaction cup 4, the driving device 2 drives the vibrating device 1 to move downwards, so that the vibrating rod 1-2 is in contact with the upper surface of the reaction cup 4, the ultrasonic vibration generated by the piezoelectric ceramic 1-1 is transmitted to the vibrating rod 1-2, and the vibrating rod 1-2 drives the reaction cup 4 to vibrate, so that the blending of the solution in the reaction cup 4 is realized. The utility model transmits ultrasonic waves by the contact of the vibrating rod 1-2 and the upper surface of the reaction cup 4, and the vibrating rod 1-2 is not in direct contact with reaction solution, thereby not only improving the uniform mixing effect, but also avoiding cross contamination.
In order to ensure that the vibration rod 1-2 is in contact with the upper surface of the reaction cup 4, the diameter of the vibration rod 1-2 is larger than the diameter of the reaction cup 4.
Further, the driving device 2 may adopt a structure form of a lead screw motor, specifically, the driving device 2 includes a carrier device 3 and a lead screw motor 2-1 fixed on the carrier device 3, an output end of the lead screw motor 2-1 is connected with a slider 2-2 in a threaded manner, and the slider 2-2 is fixedly connected with the piezoelectric ceramic 1-1. When the screw motor 2-1 drives the screw to rotate, the sliding block 2-2 can move up and down along the screw, so that the vibrating device 1 is driven to move up and down.
Preferably, in order to enhance the stability of the sliding block 2-2 moving up and down relative to the screw motor 2-1, the carriage device 3 may be provided with a guide rail 2-3 slidably connected to the sliding block 2-2 and a guide rail fixing seat 3-2 for fixing the guide rail 2-3.
Further, a photoelectric switch 2-5 is arranged on the guide rail fixing seat 3-2, and a photoelectric switch catch 2-4 is arranged on the sliding block 2-2.
When a reaction cup 4 loaded with a reaction solution under a vibrating rod 1-2 needs to be uniformly mixed, a lead screw motor 2-1 in a driving device 2 rotates to drive a sliding block 2-2 to move downwards, and further drive piezoelectric ceramics 1-1 and the vibrating rod 1-2 to move downwards, when a photoelectric switch separation blade 2-4 is away from a photoelectric switch 2-5 by a preset distance, the lower surface of the vibrating rod 1-2 is in contact with the upper surface of the reaction cup 4, the piezoelectric ceramics 1-1 generates ultrasonic vibration and transmits the ultrasonic vibration to the vibrating rod 1-2, so that the reaction cup 4 is driven to vibrate, and the reaction solution is uniformly mixed, wherein the photoelectric switch separation blade 2-4 and the photoelectric switch 2-5 are mainly used for ensuring that the vibrating rod 1-2 is in contact with the upper surface of the reaction cup 4, and the reaction cup 4 cannot be crushed due to overlarge moving distance.
After the blending process is finished, a screw motor 2-1 in the driving device 2 rotates to drive a sliding block 2-2 to move upwards, and the moving distance of the vibrating rod 1-2 is limited when a photoelectric switch 2-5 is blocked by a photoelectric switch blocking piece 2-4.
Preferably, a vibrator mounting frame 3-1 is arranged between the vibration device 1 and the sliding block 2-2, and the vibrator mounting frame is mainly used for mounting the vibration rod 1-2 right above the reaction cup 4 while realizing the fixed connection between the piezoelectric ceramic 1-1 and the sliding block 2-2, so as to facilitate the uniform mixing of reaction solution.
