Flow out. In the natural drip beverage preparation container 87, since the interaction time between the food material and the hot water in the beverage preparation container 87 is short, when a tea beverage such as black tea or green tea is prepared, a beverage having a long soaking time is required. The cooking effect is less than ideal.

Some conventional beverage brewing machines reduce the amount of water per unit time by reducing the diameter of the bottom outlet of the beverage preparation container, and prolong the time that the hot water stays in the beverage preparation container to obtain the food soaking effect; Inaccurate control, often occurs, for example, when the amount of water is too small to accumulate excess water in the beverage preparation container and overflows. Shape, or too much water can not get the ideal food soaking effect.

A beverage preparation container for use in a commercially available electric coffee maker has been designed with a leak-proof gasket that utilizes an elastic member to maintain its bottom end outlet normally closed, but the function is to enclose the beverage preparation container from the electric coffee maker. The bottom outlet prevents the residual coffee liquid, the food material or the residue after the follicle in the beverage preparation container from polluting the environment; if the beverage preparation container with the normally closed leakproof gasket is placed in the electric coffee furnace, One of the struts or the like of the electric coffee maker opens the leak-proof gasket so that the bottom end outlet is opened, so that the coffee prepared in the beverage preparation container flows into a storage container in a natural dripping manner. Storage, therefore, a beverage preparation container having a normally closed leak-proof liner in a commercially available electric coffee oven is still a natural dripping beverage preparation method when extracting coffee, and is not suitable for preparing a long soaking time such as tea. Drink.

The beverage preparation container 10 is used in an example of a beverage brewing machine as shown in FIG. 7, which presets the foodstuff and accepts the hot water dispensed by the beverage brewing machine so that the foodstuff interacts with the hot water. A beverage is prepared, which is discharged from the water outlet 11 of the beverage preparation container 10 to the outside; the beverage preparation container 10 of the present invention is different from the conventional beverage preparation container 87 shown in FIG. 7 in that it further comprises a closure The normally closed leak stop device 20 of the water outlet 11. When the beverage preparation process is performed, the leakage preventing device 20 is maintained in a closed position, so that the foodstuff and the hot water cannot flow out, and are soaked in the beverage preparation container 10 for a period of time for preparing a beverage having a better taste and quality. For example, black tea, green tea and other tea drinks.

The leakage preventing device 20 has a transmission rod 21 on both sides thereof. By pushing the transmission rod 21 upward, the leakage preventing device 20 can be displaced from a closed position to an open position, so that the beverage preparation container 10 has been mutually immersed. The beverage after a set period of time flows out to the outside, for example, flows out to the storage tank 88 as shown in FIG.

The leak stopping device 20 can also use the displacement control to open and close each Kinds of valves, such as needle valves.

The immersion control device further includes a drive motor 30 such as a reduction motor or a phase motor; a movable roller 50 coupled to a motor shaft 31 of the drive motor 30 by a coupling 40. As shown in FIG. 4, one of the roller shafts 51 of the movable roller 50 and the motor shaft 31 of the drive motor 30 are located at an asymmetrical position of the coupling 40, so that when the motor shaft 31 rotates, it can be driven. The movable roller 50 performs an eccentric rotation motion.

Referring to FIG. 1 again, the immersion control device further includes a swing arm 60 capable of performing a lever movement about a point 61, and has a first end portion 62 and a second end portion 63. When the leak stop device 20 is in the closed position, the first end portion 62 is located just below the transmission rod 21 at a slight distance. A roller frame 64 is disposed on the second end portion 63. The movable roller 50 extends into the roller frame 64. When the movable roller 50 performs an eccentric rotation motion, the roller frame 64 can be driven along with the swing arm. 60 acts as a lever in a set range, causing the first end portion 62 to drive the transmission rod 21 to reciprocate the motion between an open position and a closed position.

As shown in FIG. 1, when the movable roller 50 is at the top dead center position, the first end portion 62 of the swing arm 60 does not contact the transmission rod 21 of the leakage stop device 20, and no force is applied to the transmission rod 21 The normally closed leak stop device 20 is held in the closed position.

Similarly, when the motor shaft 31 is rotated forward or reverse by an angle of, for example, 180 degrees, the movable roller 50 can be moved back from the bottom dead center position to the top dead center position, and the leak stop device 20 is moved from the open position. Go back to the closed position.

The driving motor 30 is a small speed reducing motor having a rotation speed of, for example, 15 rpm. It can be inferred that the time required for the rotation of 180 degrees is 2 seconds. Therefore, by controlling the rotation time of the driving motor 30, the precision can be accurately driven. The movable roller 50 is at the top dead center position and the bottom dead center Eccentric rotation between positions. The drive motor 30 can also be a phase motor or other drive motor.

When brewing the beverage, an appropriate amount of hot water is first discharged into the beverage preparation container 10, and when the soaking time program is executed, the automatic control system starts the driving motor 30 to rotate for 2 seconds, and the motor shaft 31 is rotated by 180 degrees, that is, the motor is turned to the lower limit position to stop. At the same time, the transmission rod 21 of the leak stop device 20 is moved up to the soup outlet position, and when the soup discharge time (for example, 15 seconds) is completed, the automatic control system starts the drive motor 30, and when it is turned to the top dead center position, the drive motor 30 is turned off.

The amount of movement of the transmission rod 21 can be estimated from the eccentric amount of the roller shaft 51. The position of the movable roller 50 causes the leakage preventing device 20 to maintain an appropriate distance from the beverage preparation container 10 at the upper limit to avoid collision, so that the leakage preventing device 20 In the closed position, a proper spacing is maintained with the swing arm 60 so that the beverage preparation container 10 does not collide with the swing arm 60 when it is removed or loaded from the beverage brewing machine.

The upper and lower lengths of the roller frame 64 are slightly wider than the movable roller 50, and the left and right widths make the movable roller 50 not interfere with the rotation, so that the movable roller 50 rotates synchronously to move the swing arm 60; the advantages are: 1. accurate displacement, 2. related mechanism No collision problem, 3. No noise, 4. There is almost no friction between the movable roller 50 and the roller frame 64, and the life is long.

In addition, the present invention can also use at least one limit control element that can immediately stop the drive motor 30 from rotating when the drive motor 30 is rotated to a set angle. The at least one limit control element is one selected from the group consisting of a proximity switch, a micro switch, a reed switch, and a position detector.

As shown in FIG. 5, the coupling 40 is provided with a bump 41 at the top edge of the rotation to the top dead center position, and a top dead center proximity switch is suspended at a set distance directly above the bump 41. 70; when the top dead center proximity switch 70 detects that the bump 41 moves within a set distance, immediately sends a control signal, and is controlled by a control unit (not shown) of the beverage brewing machine, and immediately controls The drive motor 30 stops rotating, and the movable roller 50 is accurately stopped at the top dead center position. Similarly, as shown in FIG. 6, the creation may also set a dead-end proximity switch 71; when the bottom dead-end proximity switch 71 detects that the bump 41 moves within a set distance, That is, a control signal is issued, and the control unit immediately controls the drive motor 30 to stop rotating, so that the movable roller 50 is accurately stopped at the bottom dead center position.

When the soaking control device for the beverage preparation container provided by the present invention is compared with the aforementioned conventional technology, since the collision driving and the transmission member such as an electromagnet or an electromagnetic solenoid are not used in the present creation, no component is generated during the transmission process. The noise caused by collisions can effectively reduce the noise during transmission and prolong the service life of the transmission components. Moreover, the design uses a limit switch, a micro switch, a position detector, etc. to control the rotation angle of the drive motor. , can accurately control the displacement stroke or rotation angle of each transmission member, to improve its control accuracy and avoid malfunctions.
