The first fixing bracket 210 is provided with a piston accommodating cavity 2101, two opposite side walls of the first fixing bracket 210 respectively extend outwards along the moving direction of the piston accommodating cavity 2101 to form a capsule accommodating cavity 111, the piston accommodating cavity 2101 is communicated with the capsule accommodating cavity 111 to form a moving channel 2102, the piston 220 is accommodated in the piston accommodating cavity 2101, and the piston 220 can be driven to do reciprocating linear motion in the moving channel 2102 by arranging a driving device connected with the piston 220, so that the piston 220 pushes the capsule cup 20 in the capsule accommodating cavity 111 to move, and fruit capsules in the capsule cup 20 are injected into the crushed ice brewing system 300.

When the piston 220 is in the standby state, the piston 220 is completely accommodated in the piston accommodating chamber 2101; when the piston 220 is in the working state, the piston 220 can make a reciprocating linear motion or pause in the motion channel 2102, and at least a part of the piston 220 is located in the capsule accommodating cavity 111.

The upper case assembly 120 is disposed over the capsule accommodating chamber 111. The upper case assembly 120 includes an upper cover 121, a first cover plate 122, and a second cover plate 123. The first cover plate 122 is located above the second cover plate 123, wherein the first cover plate 122 is provided with a first opening 1221, the second cover plate 123 is provided with a second opening 1231, and the first opening 1221, the second opening 1231 and the capsule accommodating cavity 111 are vertically communicated with each other.

When the piston 220 moves toward the direction of the stirring cavity 341, the piston 220 presses the bottom of the capsule cup 20, so that the solid fruit capsule in the capsule cup 20 is injected into the stirring cavity 341.

Referring to fig. 15 and 16, the first hook 2202 of the piston 220 is located in the first guide portion 211, the first hook 2202 is movable in the first guide portion 211, the latch 2203 is located in the second guide portion 212, and the latch 2203 is movable in the second guide portion 212.

In the process that the first hook 2202 drives the second hook 2412 to move in the direction away from the stirring cavity 341, the connecting part 241 drives the return spring 250 and the gas spring 214 to move in the same direction, and because the first guide 211 is in the shape of a slide way, the outer side of the first guide 211 is changed from a curved surface into a straight surface, the height of the end where the curved surface is located is higher, and the height of the end is greater than that of the second hook 2412, when the first hook 2202 drives the second hook 2412 to move to the connecting part of the straight line and the curved line of the first guide 211, the first guide 211 can jack up the connecting part 241, and meanwhile, the return spring 250 and the gas spring 214 are forced to be stretched, and the second return spring 217 is forced to be extruded in the direction away from the first fixing support 210; when the second hook 2412 and the first hook 2202 move to the highest point of the curved portion of the first guide 211, the second hook 2412 and the first hook 2202 disengage, the return spring 250 and the gas spring 214 rebound without the force of tension, and the connection member 241 is driven to move toward the stirring chamber 341, and the second return spring 217 returns to the initial state without the force of tension, and the connection member 241 is driven to attach to the surface of the first fixing bracket 210.

It is to be understood that, in the above embodiment, the second return spring 217 is not necessary, and the holding device 240 may return to the initial state and position under the action of the return spring 250 and the gas spring 214 after the first hook 2202 and the second hook 2412 are disengaged. The gas spring 214 may serve to reduce the speed and noise during the resetting of the clamping device 240.

After the capsule cup 20 falls, the piston 220 can close the material inlet 3410 when the first fixing support 210 moves further relative to the stirring cavity 341, wherein the size of the material inlet 3410 is matched with the size of the front end of the piston 220, so that the front end of the piston 220 can be partially positioned in the stirring cavity 341, and a sealing ring 221 (shown in fig. 11) is sleeved at the front end of the piston 220, when the front end of the piston 220 is positioned in the stirring cavity 341, the outer side of the sealing ring 221 is tightly attached to the inner side wall of the material inlet 3410, so that the piston 220 can completely close the material inlet 3410, and gas or liquid in the stirring cavity 341 is prevented from flowing out from the material inlet 3410.

When the front end portion of the piston 220 is located in the stirring chamber 341, the piston 220 may simultaneously close the material inlet 3410 and the gas outlet 342 to block the communication between the inside and the outside of the stirring chamber 341; in the case where the inside of the stirring chamber 341 is in a closed state, when the piston 220 is slightly moved backward with respect to the stirring chamber 341, the front end of the piston 220 may close only the material inlet 3410 without closing the gas outlet 342, so that the inside of the stirring chamber 341 may communicate with the outside through the gas outlet 342.

It can be seen that when the piston 220 closes the inlet 3410 and the outlet 342 at the same time, the stroke of the piston 220 is larger than that when the piston 220 closes only the inlet 3410, and the stroke when the piston 220 closes only the inlet 3410 is larger than that when the piston 220 presses the capsule cup 20, so that the solid fruit capsules in the capsule cup 20 enter the stirring cavity 341.

In the process of crushing ice, the bone positions 345 can increase the friction of ice blocks, so that the ice blocks are prevented from idling; in the cleaning process, water rapidly rotates along with the ice crushing blade 343 and collides with the bone 345, so that the water level rises, and the top and dead corners of the upper cavity 341A are cleaned. Preferably, the height of the inward protrusion of the bone 345 in the upper cavity 341A is gradually increased from top to bottom, so as to further increase the friction of the ice cubes in the cavity during the ice crushing process.
