Description

Liquid sampler

Technical Field

The utility model relates to a pharmacy field especially relates to a liquid sampler.

Background

The production of liquid materials and liquid products relates to various fields of life and production, and a liquid sampler is widely applied to liquid sampling in the industries of medicines, videos, cosmetics, chemical engineering and the like, and the liquid materials or the liquid products are sampled by the following methods at present.

(1) The sampling cup with a handle with a proper length is used for directly sampling, the liquid sampling can only be calculated to obtain a certain volume of liquid sample, but in the sampling process, the used sampling device can bring violent movement of the liquid, and meanwhile, the liquid which enters a non-sampling area in the sampling cup in advance can not escape from the movement process to empty the sampling cup for the liquid in a preset area. Therefore, the liquid taken is not a sample of the designated area that we wish to measure.

(2) The sampling of the liquid is carried out by using a sampling tube or a sampler after collection of the sampling tube, and the sampling mode is mainly used for monitoring and sampling of a liquid tank in the production process, and the sample of a specified area cannot be obtained.

If a liquid sample in a designated area is to be taken, the specific measure is to keep a certain amount of air in a sampling tube (sampler), move the sampling tube to the position where the sample is to be taken, and take the sample later. However, the problem with this sampling method is that the sampling tube is relatively large or soft and inconvenient to handle. The sampling area cannot be located quickly and effectively. Sampling liquid in a designated area is also an indispensable sampling mode for production detection.

In view of the above-mentioned drawbacks, the present designer is actively making research and innovation to create a liquid sampler that can meet the requirement of accurate sampling of various liquids in a laboratory, so that the liquid sampler has industrial utility value.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Fig. 1 and fig. 2 show a liquid sampler, including hollow barrel 1 and pull rod 2, funnel-shaped inlet 3 that is linked together with hollow barrel 1 inner chamber is seted up to hollow barrel 1's bottom, pull rod 2's bottom activity is fixed with end cap 4, end cap 4's bottom is equipped with the funnel-shaped lower part that agrees with mutually with funnel-shaped inlet 3, pull rod 2's bottom is seted up the inner wall and is had the internal screw thread screw hole, be equipped with the external screw thread with screw hole looks adaptation on the outer wall at end cap 4 top, the activity is fixed with on hollow barrel 1's the outer wall and can be along the gliding measuring block 5 from top to bottom of scale mark.

The utility model provides a liquid sampler's principle as follows:

1. inserting the combined liquid sampler into the liquid to be sampled to reach the required depth;

2. if a certain amount of liquid is needed, before sampling, after the measuring block 5 is moved to a proper position on the scale mark, the inner pull rod 2 of the sampler is pulled upwards, when the plug 4 at the bottom of the pull rod 2 reaches the position of the measuring block 5, the inner pull rod 2 of the sampler is kept in a pulled state and is slowly inserted into the liquid, and the liquid at the corresponding position enters the sampler in the process of inserting the liquid into the sampler;

3. after the liquid enters the liquid sampler, the pull rod 2 is put down, and the liquid sample is sealed in the sampler;
