Embodiment 1

[0067] A fluid guiding device such as Figures 7A-7B As shown, it includes a tapered piston 19 and a tapered piston guiding part 5, the tapered piston 19, and the tapered piston 19 can be made of elastic material, such as Figures 5A-5B As shown, the conical piston 19 includes a conical portion 191, and the middle part of the bottom surface of the conical portion 191 is provided with a guiding column 192, and the bottom surface of the conical portion 191 is also provided with a plurality of diversion grooves 191a. In this embodiment, there are four diversion grooves 191a, which are evenly distributed along the bottom surface of the tapered part 191, and the diversion grooves 191a extend from the edge of the bottom surface of the tapered part 191 to the guide post 192, so The tapered portion 191 can be conical or have a pyramidal shape such as a triangular pyramid, a quadrangular pyramid, etc., such as Figures 5A-5B , the tapered portion is a cone;

[0068] The conical pisto...

Embodiment 2

[0076] The difference from Example 1 is that, as Figure 5C As shown, the conical piston 19' can be made of elastic material without the airtight ring receiving groove 191b and the airtight ring 21, and the conical surface of the conical part 191 is provided with the conical part 191. Formed airtight structure 191c.

Embodiment 3

[0078] A fluid guiding device such as Figures 10A-10B As shown, it includes a tapered piston 20 and a tapered piston guide 5', Figure 8A The middle cone piston 20 is Figure 5A A modified example of the tapered piston 19, the tapered piston 20 includes a tapered portion 201, such as Figures 8A-8B As shown, the middle part of the bottom surface of the conical part 201 is provided with a guiding post 202, and the guiding post 202 is a circular cylinder, and the bottom surface of the conical part 201 is also provided with a plurality of first guide grooves 201a , the first guide groove 201a includes four, uniformly distributed along the bottom surface of the tapered part 201, the first guide groove 201a extends from the edge of the bottom surface of the tapered part 201 to the guide A column 202, the alignment column 202 is also provided with a plurality of second flow guiding grooves 202a connected with the first flow guiding groove 201a, and the second flow guiding grooves...

Abstract

The invention relates to a fluid guiding device including a taper piston and a tapered piston guide part. The tapered piston includes a tapered part. The center of the bottom face of the tapered partis provided with a guide post. The bottom face of the tapered part is also provided with a plurality of fluid guiding grooves extending to the guide post from the edge of the bottom face of the tapered part. The front part of the tapered piston guide part includes a top hole and a guide channel. The guide post is inserted into the guide channel fitting with the guide post. The channel wall of theguide channel is provided with an exhaust groove formed along the length direction of the guide channel. The guide channel and the exhaust channel are connected with the top hole. When the guide postis inserted into the guide channel completely, the exhaust channel can be connected with the guide channel. The invention also relates to a vacuum container adopting the above fluid guiding device. The container is long in vacuum maintaining time, simple in structure and convenient to transport.

Description

technical field [0001] The invention relates to a guiding device and a vacuum container with the guiding device, in particular to a fluid guiding device and a vacuum container with the fluid guiding device. Background technique [0002] Generally speaking, in family life or industrial production process, there is usually a need to store items in a vacuum environment, for example, food or industrial raw materials that are easily affected by changes in the surrounding environment are stored in a vacuum environment. However, the anti-leakage mechanism of commercially available household vacuum storage boxes is too simple to maintain a long-term vacuum, while the anti-leakage mechanism of industrial vacuum storage systems is too complicated to cause high cost and is not conducive to transportation. Contents of the invention [0003] The present invention aims at the deficiencies of the above-mentioned prior art, and provides a fluid guide device that maintains vacuum for a lon...
