Description

Mixing device of automatic mixing instrument

Technical Field

The application relates to the technical field of experimental instruments, in particular to a blending device of an automatic matching and marking instrument.

Background

Laboratory analytical determinations often require the configuration of standard curves, primarily for analytical measuring instruments. Due to changes in ambient temperature and humidity, different life of instrument consumables, changes in detector sensitivity over time, etc., periodic calibration of analytical instruments is essential. Sometimes, in order to detect whether the measurement result of the instrument is reliable at any time, several standard substances are often added in the batch analysis and measurement process to confirm the reliability of the analysis and measurement data of the whole batch of samples. In these works, the arrangement of the standard is an important matter, and is a process which is particularly time-consuming, material-consuming and error-prone. Therefore, the automatic standard matching instrument for the existing finished products on the market can replace manual work and liberate experimental analysts from tedious and fussy work.

Except for the automatic blending function, the performance of most procedures of the existing finished product automatic blending instrument can meet the requirements of analysis and measurement work. Most automatic matching instruments adopt the following two ways to mix evenly: 1. after the pause, the software prompts the operator to shake up manually. And after the operation is finished, the standard matching instrument continues the following work flow. 2. And blowing bubbles into the container by using a liquid adding pump, and driving the solution to flow up and down and mix uniformly in the rising process of the bubbles. The manual operation mode is low in working efficiency, and the significance of automatic label matching is lost due to the fact that the manual operation mode depends on real-time assistance of an operator. The advantages are that the bubble mixing can be automatically completed, but the mixing effect is poor, especially when the concentration of the standard sample is low, the mixing is more obvious, and the mixing is not suitable for the mixing of volatile samples. Automatic priming systems using peristaltic or syringe pumps can reduce some manual operations and risks, but also have many disadvantages.

Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise.

In the description of the present application, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically, electrically or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship.

an elastic support member fixedly disposed on the sample holder;

a base connected to the elastic support member to support the sample holder;

and an ultrasonic generator for generating ultrasonic vibration to the base until mechanical vibration generated by the ultrasonic vibration is transmitted to the sample holder through the elastic support member.

As to the implementation of the particular configuration of the sample holder, it is easily envisaged that it may be of a form common in the art. For example, the sample vessel may be a plate-like member having a plurality of receiving holes for receiving the sample vessels.

The elastic support member has elasticity capable of amplifying the amplitude of the ultrasonic vibration during the transmission of the ultrasonic vibration so that the amplitude of the vibration finally acting on the sample holder is sufficient to bring about the oscillation effect of the vessel in which the sample holder is placed.

To achieve this desired objective, the resilient support may be a tension spring.

Of course, any member having elasticity may be used without being limited to the extension spring and the like.

As an exemplary implementation of the number of resilient supports, there may be four as represented in fig. 1. In this number of implementations, the resilient supports are located at four corners of the sample holder. The elastic supporting pieces in the number can transmit mechanical vibration caused by ultrasonic vibration of the ultrasonic generator to the sample holder more comprehensively.

In an exemplary embodiment, the ultrasonic generator is disposed at the mount in an orientation such that vibrations of the mount are transmitted in three orthogonal directions.

Thus, the blending effect can be improved through three orthogonal directions

In an exemplary embodiment, the base is provided with a boss for mounting the ultrasonic generator.

The boss may be cylindrical or block-shaped. It is readily contemplated that the boss may be provided with a removable mounting member such as a placement slot or bolt member for ease of placement of the ultrasonic horn.

In order to accurately control the vibration amplitude, phase and frequency of a plurality of ultrasonic generators, various waveforms can be combined, solution molecules can be diffused in various directions, and the ultrasonic generator vibration control device further comprises a controller electrically connected with the ultrasonic generators.

The above description is only for the preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present application should be covered within the scope of the present application.
