Problems solved by technology
When sampling the air, it is often necessary to use a new filter membrane and replace the filter membrane with the sample sheet to be tested. In order not to contaminate the new filter membrane and the sampled filter membrane, the filter holder and the filter membrane holder are usually used in the prior art. Two independent devices are placed in the box to hold the filter membrane. This method is a waste of space. Carrying too many devices is likely to cause omission and loss. In addition, the filter membrane clip is easy to lose the sample on the filter membrane during the carrying process, resulting in detection error

Embodiment Construction
[0017] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0018] Such as Figure 1-3 Said, a sampling clip assembly for an air sampler, comprising an upper box cover 1, an upper clamping ring 2, an inner pressure ring 3, a lower clamping ring 4, a lower box cover 5, an upper clamping ring 2, The inner pressure ring 3 and the lower clamp ring 4 form a filter membrane clamp, and the upper clamp ring 2 and the lower clamp ring 3 sample a ring-shaped embedded structure. The lower box cover 5 is a stepped cylinder with a small top and a large bottom including a first cylinder 51 and a second cylinder 52. The side of the second cylinder 52 is provided with a groove along the circumferential direction, and a filter membrane is connected in the groove. Hold ...

The invention discloses a sampling holder component for an air sampler. The sampling holder component comprises an upper box cover, an upper grip ring, an inner press ring, a lower grip ring and a lower box cover which are sequentially connected from top to bottom, wherein the upper grip ring, the inner press ring and the lower grip ring form a filter membrane clamp; the lower box cover is a stepped cylinder including both a first cylinder and a second cylinder and provided with a smaller upper part and a larger lower part; a groove is formed in the side surface of the second cylinder in the circumferential direction; the interior of the groove is connected with a filter membrane holding box. The filter membrane holding box is convenient to take for use, and by adoption of the integral design, the space is saved, and the sampling holder component is convenient to carry out.
Description
technical field [0001] The invention relates to a sampling clip assembly for an air sampler. Background technique [0002] Air filter clips are usually used to detect air quality. The particulate objects in the air are collected through the filter membrane placed in the sampling clip, and then the particulate objects on the filter membrane are analyzed and detected to evaluate the air quality. When sampling the air, it is often necessary to use a new filter membrane and replace the filter membrane with the sample sheet to be tested. In order not to contaminate the new filter membrane and the sampled filter membrane, the filter holder and the filter membrane holder are usually used in the prior art. Two independent devices are placed in the box to hold the filter membrane. This method is a waste of space. Carrying too many devices is likely to cause omission and loss. In addition, the filter membrane clip is easy to lose the sample on the filter membrane during the carrying p...
