Filling container

1. A filling container, comprising:

a joint, wherein a side of the joint is provided with an inlet, another side of the joint is provided with a tube insertion cavity, and an inner end of the tube insertion cavity is connected to the inlet;

a hollow tube bundle, comprising several hollow tubes, wherein an upper part of the hollow tube bundle is entirely inserted into the tube insertion cavity;

a container, mounted at a lower end portion of a hollow tube by using an elastic fastener, wherein an inner cavity of the container is in communication with an inner passage of the hollow tube; and

a holding mechanism, mounted on the joint at the tube insertion cavity, wherein the holding mechanism enables the tube insertion cavity to contract and hold the hollow tube bundle,

wherein the side of the joint extends outward to form a clamping groove; and the holding mechanism is a compression block, the compression block is detachably mounted inside the clamping groove, and the clamping groove cooperates with the compression block to enclose the tube insertion cavity.

2. The filling container according to claim 1 , wherein a lower part of the joint is connected to a rubber sleeve, a lower-end open mouth of the rubber sleeve forms the tube insertion cavity, and the upper part of the hollow tube bundle is inserted into the rubber sleeve; and the holding mechanism comprises a banding apparatus surrounding a peripheral portion of the rubber sleeve, and the banding apparatus contracts and bands the rubber sleeve and enables the rubber sleeve to hold the hollow tube bundle.

3. The filling container according to claim 1 , wherein a fixed block is formed on two sides of the compression block, a slide groove matching the fixed block is formed on a side wall of the clamping groove, and the fixed block is fixedly connected to the slide groove by using a fastener.

4. The filling container according to claim 3 , wherein a compression surface of the compression block is a plane; and the compression surface cooperates with an inner side wall of the clamping groove to form a square bayonet.

5. The filling container according to claim 4 , wherein the hollow tube bundle comprises several hollow tube layers, and a first seal soft cushion is disposed between two adjacent hollow tube layers.

6. The filling container according to claim 3 , wherein a second first seal soft cushions disposed between the hollow tube bundle and a side wall of a bayonet.

7. The filling container according to claim 1 , wherein the hollow tube bundle is formed by combining several hollow tubes having an orthohexagnal cross section, so as to form a hollow tube bundle having a honeycomb-shaped cross section; or the hollow tube bundle is formed by combining several hollow tubes having a circular cross section.

8. The filling container according to claim 1 , wherein a filtering block is disposed inside a passage that connects the inlet and the tube insertion cavity inside the joint, several through holes running from top to bottom are formed on the filtering block, and the filtering block is disposed above the clamping sleeve.

9. The filling container according to claim 8 , wherein a step is formed on an inner wall of the passage that connects the inlet and the tube insertion cavity inside the joint, an upper end of the filtering block abuts against the step, and a lower end of the filtering block abuts against an upper end of the hollow tube bundle.
