At this time, since the cup body 201 has been inserted by the water injection needle 445 and the cup lid 202 is pierced by the piercing member 52, the process of water injection and brewing can begin. Therefore, in this state, the drink material cup 200 reaches the predetermined brewing time. Location.

Once the control unit receives the electrical signal generated by the second sensing element corresponding to the cup lid 202 abutting the chassis 51, the control unit controls the water supply unit 3 to provide hot water for brewing into the drink material cup 200 via the water injection needle 445, thereby The brewing is performed, and the beverage produced by the brewing is allowed to flow out through the water outlet 12.

After a predetermined brewing time (the brewing time can be calculated according to the predetermined brewing volume and the flow rate of the water pump in the water supply unit 3), the control unit controls the water supply unit 3 to stop providing hot water, and controls the drive unit 42 to drive the wire The bar 43 rotates in the reverse direction, so that the brewing chamber 44 moves backward and returns to the rear position before the brewing starts. During this process, the beverage raw material cup 200 will initially move slightly backwards driven by the water injection needle 445, so that the cup lid 202 will be separated from the filter member 5 first. After the beverage raw material cup 200 reaches the limiting member 45, it will be limited by the limiting member 45 and cannot follow the receiving portion 442 to move backward. In this state, the water injection needle 445 continues to move backwards with the brewing chamber and separates from the raw drink cup 200. The raw drink cup 200 loses support and falls into the raw cup collection part 7 from the waste channel 41B and the collection part opening 7A. The entire brewing process That's the end.

The function and effect of the embodiment

According to the brewing positioning mechanism and the beverage preparation machine provided in this embodiment, since the top of the frame has an entrance channel, and the bottom end of the entrance channel is provided with a stopper, the drink material cup can be put into the brewing positioning mechanism from above and be Restricted to the position of the limit piece; at the same time, the filter mechanism is located between the limit piece and the brewing bin, and the driving part only needs to drive the brewing bin to move linearly to allow the receiving part in the brewing bin to drive the drink material cup to move , So that the drink material cup reaches the predetermined brewing position at the filter mechanism. Therefore, in the brewing positioning mechanism of this embodiment, the entry of the beverage raw material cup is a natural downward movement realized by gravity in the vertical direction, and the driving part and the brewing chamber only need to perform simple linear movement to realize the brewing positioning. On the one hand, the space of each mechanism is compact, which can better achieve miniaturization. On the other hand, it does not require a complicated transmission mechanism, the overall structure is simple, and it is easier to maintain.

In the embodiment, since the number of the stopper is two, the two stoppers are arranged opposite to each other and can be close to or far away from each other, and the lower part of the inner surface of the side of the stop groove in the stopper is curved. The distance between the bottom ends of the tank is still smaller than the diameter of the cup eaves. Therefore, the limiter can clamp and limit the drink material cup when it slides, and can move away from each other when the brewing chamber drives the drink material cup to move forward. And let the drink raw material cup detach. Furthermore, the limiting member can also limit the beverage raw material cup again when the brewing chamber moves backward to prevent the beverage raw material cup from being driven by the water injection needle to move backward. Therefore, the embodiment adopts a simple structure to achieve three functions: the vertical limit of the drink material cup after sliding down, the release of the limit when brewing, and the limit again in the horizontal direction after the end of the brewing. And with the cooperation of the brewing bin, the beverage raw material cups are moved in the sequence of pressing, sliding, moving forward, moving back, and falling to complete the entire brewing process.

In the embodiment, since the frame is provided with a waste channel under the limiter, and a raw material cup collection part is also provided under the waste channel, after the brewing is completed, the used beverage raw material cups can be dropped directly into the raw material cup for collection Part, there is no need to provide another structure for moving the used beverage material cup, and there is no need for the user to manually take out the beverage material cup.

The foregoing embodiments are preferred cases of the present invention, and are not used to limit the protection scope of the present invention.

For example, in the embodiment, the limit groove of the limit member can allow the cup eaves to enter, and it limits the position of the drink raw material cup by restricting the cup eaves. However, in the present invention, for a drink material cup without a cup eaves, the width of the limit groove in the horizontal direction can also be set to be the same as the thickness of the drink material cup, so that the limit piece can also be used for the drink material cup. Limit.

In the embodiment, the limiting member is movably installed on the frame body through the installation of the guide post. In the present invention, the limiting member can also be movably installed on the frame body in other ways, for example, directly on the frame body. Guide the groove and let the stopper fit into the guide groove.

In addition, in the embodiment, the lower part of the rear side of the housing is provided with a circuit board warehouse. There is still free space in this position. A water tank for storing cold water can also be placed as needed; in addition, the storage warehouse can also be replaced with a water tank, so that The beverage preparation machine of the present invention is more convenient to use.
