Description

Technical Field

[0002] A Chinese patent (publication number: CN215917174U) provides an oscillating heating device, including a shell, a machine cover is provided on the top of the shell, a temperature control mechanism is fixedly connected to the lower part of the machine cover and the inner upper end of the shell, an oscillation disk mechanism is fixedly connected to the lower part of the temperature control mechanism and the middle part of the shell, and an oscillator is fixedly connected to the lower part of the shell under the oscillation disk mechanism. The utility model is provided with a heating plate and a temperature sensor in the device, and a microcomputer forms a closed-loop control of the heating plate with the parameters of the temperature sensor to perform constant temperature regulation. A groove is provided above the oscillation disk for placing a sample bottle, and the oscillation disk is supported by a support spring to facilitate the back and forth oscillation of the oscillation disk. A cover is provided on the top of the device to fix the top of the sample bottle.

[0003] The above scheme fixes the sample bottle by setting a groove, which can only be applied to test tube containers of a single size, and cannot be applied to tray containers. In addition, the existing tray containers have various sizes and shapes, and the above scheme is even more inapplicable. Furthermore, if tray containers are used to perform some chemical experiments that require shaking, the shaking process can only be carried out by manual shaking, so the shaking intensity and time cannot be effectively controlled, which affects the experimental results. There are also safety hazards due to long-term manual shaking or irregular shaking by scientific researchers.
