The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The following detailed description of the embodiments of the invention is provided.

An expandable gene detection sample storage device, as shown in fig. 1 to 4, comprises a base cylinder 1, a liquid inlet cylinder 2 with an opening 13 and arranged at the upper end of the base cylinder, and a liquid storage cylinder 3 with a closed bottom and arranged at the lower end of the base cylinder; adjusting the storage capacity by changing the combined length of the liquid inlet cylinder and the base cylinder and/or by changing the combined length of the liquid storage cylinder and the base cylinder; the liquid storage cylinder comprises a straight cylinder part 4 and a spherical part 5 with a hemispherical lower end, and a hemispherical groove 6 which is concave downwards is arranged at the lowest edge of the spherical part.

The hemispherical groove is arranged at the lowest edge of the liquid storage cylinder, so that the sampling devices such as a suction tube and the like can conveniently suck samples in the liquid storage cylinder, and the defect that the samples are not easy to suck is avoided. Meanwhile, the liquid storage barrel is hemispherical, so that the storage capacity of the device can be improved to the maximum extent under the condition that the volume of the device is slightly increased, and the device is convenient to use.

In an alternative embodiment, the inner wall of the top end of the spherical part is provided with a horizontal liquid baffle ring 7, and the outer edge of the liquid baffle ring is fixed on the inner wall of the liquid storage cylinder. Owing to set up and keep off the liquid ring, when meetting jolting or shaking in transportation or the use, the liquid in the device can not directly be in the same direction as liquid storage cylinder inner wall and spout upwards, has reduced uncovered (generally install the lid) and has located sealed burden, especially touch the shock that causes carelessly in the use, can obtain fine suppression, furthest avoids the liquid spill.

In order to increase the friction force and improve the stability when holding, the surface of the outer wall of the basic cylinder can be provided with anti-skid particles or anti-skid lines. In order to keep the device stable in the storage state, a plurality of supporting blocks 14 can be symmetrically arranged at the bottom end of the spherical part, and the lower edge of each supporting block is lower than the lowest point of the lower edge of the spherical part, so that the bottom of the liquid storage cylinder is prevented from colliding.

Usually, the lower end of the liquid inlet cylinder is screwed to the base cylinder. The upper end of the straight cylinder part of the liquid storage cylinder is screwed on the base cylinder. The screwing length of the liquid inlet cylinder and/or the liquid storage cylinder and the base cylinder is changed by screwing the liquid inlet cylinder and/or the liquid storage cylinder, so that the size of the whole storage capacity of the device can be adjusted.

In an alternative embodiment, a coarse filter ring 8 is detachably mounted on the base cylinder; the inner wall of the upper end of the foundation cylinder is provided with an upper connecting internal thread, and the outer wall of the upper end of the foundation cylinder is provided with an upper connecting external thread; the internal thread at the lower end of the liquid inlet cylinder is matched with the upper connecting external thread; the external thread at the lower end of the coarse filtering baffle ring is matched with the upper connecting internal thread.

Specifically, above-mentioned colating keeps off the ring and includes connecting portion 9 and the filter house 10 of connecting portion upper end, is equipped with a plurality of via holes 11 on the filter house, the connecting portion outer wall be equipped with last interior screw-thread fit's of being connected external screw thread, the filter house upwards extends basic section of thick bamboo, and forms feed liquor chamber 12 between the uncovered inner wall of filter house and a liquid inlet section of thick bamboo. The end surface of the top end of the filtering part is lower than the end surface of the top end of the liquid inlet cylinder. In an optional embodiment, the diameter of each through hole can be larger from the lower end and the upper end of the filter part, and the diameter of the through hole in the middle of the filter part is smaller, so that the through hole with the larger diameter at the lower end can avoid the blockage of too many through holes as far as possible while the filtering effect is ensured, and the through hole with the larger diameter at the upper end can avoid the phenomenon that a sample directly overflows into the liquid storage cylinder from the upper edge of the coarse filtering baffle ring when the adding amount is larger instantaneously.

Under the condition that needs prefilter, can keep off the ring with the colating and install in basic section of thick bamboo upper end, later to annotating sample (or solution) in the feed liquor chamber again, great impurity or fixture can separate and keep off the ring outside at the colating, can not flow into the stock solution section of thick bamboo, consequently, the colating that sets up keeps off the ring and can reach better prefilter effect.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.

The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
