## Abstract

The present disclosure relates to a beverage making device, which includes a lid, a container, an infuser and a pump for pumping liquid. The pump pumps liquid in the container to the infuser through the riser tube. A protective flow-diversion cover is sleeved over a top end of the riser tube, and the protective flow-diversion cover is provided with a water outlet. The lid of the beverage making device is provided with a protruding member extending downward. Only when the lid is closed, the protective flow-diversion cover can open the water outlet by being triggered by the protruding part. This ensures that no liquid will be ejected from the beverage making device when the lid is opened.

## Claims

### Claim 1

A protective flow-diversion cover for a riser tube of a beverage making device, the beverage making device comprising: a container for storing water or beverage; a removable lid that can attach to the container; an infuser for storing and brewing ingredients, and a pump for pumping liquid from the container to the infuser, wherein the pump pumps liquid in the container to the infuser through the riser tube,
wherein the protective flow-diversion cover includes a protective flow-diversion section and a joining section, the protective flow-diversion section having a side wall which faces the infuser, protrudes from the joining section, and is provided with a water outlet thereon, the joining section being sleeved over a top end of the riser tube and having a side wall which faces away from the water outlet and is provided with a fixture part for fixing the protective flow-diversion cover to the container; and
wherein the lid is provided with a protruding part extending downward, the protruding part being configured to trigger opening or closing of the water outlet;
when the lid is closed, the protruding part comes in contact with the flow-diversion cover to open the water outlet; and
when the lid is opened, the protruding part moves away from the protective flow-diversion cover to close the water outlet.

### Claim 2 (depends on 1)

The protective flow-diversion cover for a riser tube according to claim 1, wherein the protective flow-diversion cover is a hollow bladder structure that can be deformed, and the water outlet is a slit or slits on a side face of the flow-diversion cover that faces the infuser.

### Claim 3 (depends on 1)

The protective flow-diversion cover for a riser tube according to claim 1, wherein the protective flow-diversion cover is provided with an actuating part, and when the lid is closed, the protruding part comes in contact with the actuating part, thereby triggering the water outlet to open.

### Claim 4 (depends on 3)

The protective flow-diversion cover for a riser tube according to claim 3, wherein the actuating part is an elastic part: when the lid is closed, the protruding part comes in contact with the elastic part to open the water outlet; and when the lid is opened, the protruding part moves away from the elastic part, and the water outlet is closed under the elastic force of the elastic part.

### Claim 5 (depends on 3)

The protective flow-diversion cover for a riser tube according to claim 3, wherein the actuating part is a biased rotating part: when the lid is closed, the protruding part comes in contact with the biased rotating part, thereby opening the water outlet; and when the lid is opened, the protruding part moves away from the biased rotating part, and the water outlet is closed under the action of the biasing force of the biased rotating part.

### Claim 6 (depends on 2)

The protective flow-diversion cover for a riser tube according to claim 2, wherein the water outlet is a plurality of vertical slits disposed on a side wall of the protective flow-diversion cover, and the plurality of vertical slits are closed in a natural state.

### Claim 7 (depends on 6)

The protective flow-diversion cover for a riser tube according to claim 6, wherein the protruding part is a pressing block, and when the lid is in a closed state, the pressing block presses the protective flow-diversion cover downwardly, thereby opening the plurality of vertical slits.

### Claim 8 (depends on 1)

The protective flow-diversion cover for a riser tube according to claim 1, wherein the protective flow-diversion cover is made of silicone rubber material; and/or
the protective flow-diversion cover is provided with a fixture part for fixing the protective flow-diversion cover to the body of the container.

### Claim 9 (depends on 1)

A riser tube assembly for a beverage making device, wherein the riser tube assembly comprises the riser tube and the protective flow-diversion cover according to claim 1.

### Claim 10 (depends on 9)

A beverage making device, comprising the riser tube assembly according to claim 9.
