That is, the width of the protection ring 5 is set to be slightly larger than the distance from the top surface of the sealing block 3 to the lower surface of the upper stepped hole 11, and at this time, the moving range of the upper cover 4 is equal to the width of the protection ring 5, and when the upper cover 4 is pressed to contact the upper end surface of the upper stepped hole 11, the sealing block 3 can be pushed out, separated from the upper stepped hole 11, and dropped into the bottle body 6.

As a modification, the downward movement range of the magazine 2 can be restricted by the abutment of the upper limit ring 22 formed on the magazine 2 with the upper end surface of the lower cover 1. At this time, the size of the upper cover 4 and the width of the protection ring 5 may be set without any limitation.

FIG. 3 is a cross-sectional view B-B of the structure of the lower cover and the silo shown in FIG. 1;

as shown in fig. 3, two longitudinally (axially) extending limiting grooves 111 are symmetrically arranged on the inner wall of the upper stepped hole 11 of the lower cover 1. Go up and be provided with two fore-and-aft spacing grooves 111 corresponding to spacing groove 111 on the 11 inner walls of ladder hole for carry on spacingly in direction of rotation to feed bin 2, make feed bin 2 only can slide from top to bottom along spacing groove 111, can not rotate. The number of the stopper grooves 111 is not limited to two, and one or more stopper grooves may be provided. In this example mode, two limiting grooves 111 are symmetrically arranged, and the corresponding relation between the limiting grooves 111 and the limiting blocks 21 can be omitted when the bin 2 is installed, so that the installation is convenient at will.

As shown in fig. 3, the lower end of the stopper 21 is provided with a stopper protrusion 211, and the stopper protrusion 211 is elastically connected to the lower end of the stopper 21, protrudes outward from the stopper 21 in the radial direction, and is pushed inward in the radial direction to retract inward.

The bottom of the limit groove 111 is formed with a groove 112 corresponding to the limit protrusion 211, the groove 112 is outwardly concave in the radial direction, and the limit protrusion 211 is outwardly sprung and reset when entering the groove 112.

The positions of the limiting protrusion 211 and the groove 112 are set such that when the bin 2 moves downwards to the lower limit position, the limiting protrusion 211 enters the groove 112 under the action of elastic force, and the bin 2 is prevented from moving upwards through the matching of the limiting protrusion 211 and the groove 112.

In fig. 3, the m position is a position where the bin 2 is installed in the upper stepped hole 11, and the limit protrusion 211 is located when the upper cover 4, the protection ring 5 and the lower cover 1 are in a connected state. In fig. 3, the n position is a position (bin movement to the lowest point) when the upper cover 4 is moved downward by removing the protection ring 5 and pressing the upper cover 4 downward and the lower cover 1 is abutted.

Therefore, when the guard ring 5 is not removed, the stopper 21 enters the stopper groove 111, and is pressed by the inner surface of the stopper groove 111, the stopper projection 211 is retracted, and the end surface of the stopper projection 211 abuts against the inner surface of the stopper groove 111 by the elastic force. When the protection ring 5 is removed and the upper cover 4 is pressed downwards to enable the storage bin 2 to move downwards, the limiting protrusion 211 slides along the inner surface of the limiting groove 111 until the storage bin 2 moves to the position of the groove 112, the storage bin returns to the inside of the groove 112 under the action of elastic force, and the storage bin 2 is kept at the position after moving to the bottom through the matching of the limiting protrusion 211 and the groove 112, so that the fixing effect is achieved. Because the feed bin 2 can not move upwards any more, the feed bin 2 can not be pushed out outwards under the action of high-pressure gas in the bottle body 6, and can not fall off during use.
