[0027] For the first embodiment, please refer to Figures 1 to 6 The present application provides a flow control brewing device, in particular a hand brewing device, comprising a base 1, a filter cup 2, a ball valve chamber 3, a ball valve 4, a lever 5, a brewing seat 6 (such as Figure 7 As shown), a motor 7 and a driving wheel 8.

[0028] The base 1 has a base body 11, and a receiving space 12 (such as Figure 5 As shown in FIG. 1 , the accommodating space 12 extends to the upper end of the base 11. The filter cup 2 (or brewing cup, hereinafter referred to as the filter cup) is disposed on the base 11 of the base 1. The filter cup 2 can be placed on the base 11 by assembly or integral molding.

[0029] The ball valve chamber 3 is arranged at the bottom of the filter cup 2. The ball valve chamber 3 can be installed at the bottom of the filter cup 2 from top to bottom. The ball valve chamber 3 is a hollow body. An inner hole 31 is formed inside the ball valve chamber 3. The material of the ball valve chamber 3 can be rubber and has elasticity. The ball valve 4 can be installed in the ball valve chamber 3, and the ball valve 4 is arranged in the inner hole 31 of the ball valve chamber 3. The inner hole 31 of the ball valve chamber 3 is conical in the vertical direction, that is, the inner diameter of the inner hole 31 can decrease from top to bottom. The bottom of the ball valve chamber 3 has an outlet 32, which is connected to the inner hole 31. The diameter of the outlet 32 ​​is smaller than the diameter of the ball valve 4, so that the ball valve 4 drops to the conical wall of the ball valve chamber 3 due to the weight of the ball valve 4 itself when in the standby state to stop leakage, and will not fall down.

[0030] The outer edge of the ball valve chamber 3 may be provided with an annular concave ring 33 near the upper end, and an annular convex ring 21 may be provided at the bottom of the filter cup 2. The annular concave ring 33 and the annular convex ring 21 can be mutually engaged, so that the ball valve chamber 3 is stably engaged with the bottom of the filter cup 2, so as to facilitate the disassembly and cleaning of the ball valve chamber 3. The ball valve chamber 3 may be provided with an upper ring 34 near the upper end, and the upper ring 34 of the ball valve chamber 3 may be tightly matched with the filter cup 2 to make it watertight and impermeable. An anti-escape piece 35 may be provided at the upper end of the ball valve chamber 3, and the inner diameter of the anti-escape piece 35 is smaller than the diameter of the ball valve 4. The ball valve 4 may be a steel ball, etc. The material of the ball valve 4 may be food-grade stainless steel, but it is not limited. The anti-escape piece 35 can keep the ball valve 4 in the ball valve chamber 3 when the filter cup 2 is cleaned or moved. The ball valve chamber 3 is preferably made of food-grade temperature-resistant, water-resistant and wear-resistant rubber, so that the ball valve 4 does not have a rough surface due to collision or friction, thereby affecting the anti-leakage function.

[0031] The inner hole 31 of the ball valve chamber 3 can be designed to be conical. The main function is to use the automatic control program to move the ball valve 4 to an appropriate position. When the ball valve 4 is in different positions in the ball valve chamber 3, there are different gap differences due to the conical inner hole 31 of the ball valve chamber 3. Therefore, different flow rates can be controlled by the gap difference. The brewing flow rate is the brewing time. The brewing time directly affects the taste of the beverage, so that different brewing ingredients can be used to perform different brewing programs. The opening and closing and the soup discharge speed of the beverage are controlled by the moving position of the ball valve 4.

[0032] The lever 5 is pivoted on the base 1 by a rotating shaft 51, so that the lever 5 can swing. One end of the lever 5 extends into the accommodating space 12 of the base 11, and one end of the lever 5 has a column 52, which can be a cylinder, and the upper end of the column 52 can be an arc surface. The column 52 is located below the ball valve 4 and can be used to push the ball valve 4. The other end of the lever 5 is located outside the base 11 of the base 1, and the other end of the lever 5 is pivoted with a roller 53, and the roller 53 can be pushed by the driving wheel 8. The driving wheel 8 can be an eccentric wheel or a cam, etc. The driving wheel 8 in this embodiment is an eccentric wheel, but it is not limited.

[0033] When the filter cup 2 is in the standby state, there is an appropriate distance between the roller 53 and the push wheel 8, so that the filter cup 2 will not collide with the push wheel 8 when it is operated to position for brewing. At the same time, the upper end (arc surface) of the column 52 of the lever 5 is separated from the ball valve 4 and has a distance, so that the ball valve 4 descends by its own weight and is stuck on the conical surface of the ball valve chamber 3 to close the outlet 32, thereby achieving the function of stopping the flow of soup.

[0034] The lever 5 can be connected to an elastic component 9, which can be a tension spring, etc. The elastic component 9 can be connected between the lever 5 and the filter cup 2, and can be pulled by the tension of the elastic component 9 to make the lever 5 rise. A positioning column 54 can be provided on the outside of the lever 5, and the positioning column 54 can touch the surface position of the filter cup 2 (brewing cup) as the limit point of the movement of the lever 5. The limit point just makes the column 52 and the roller 53 at both ends of the lever 5 have an appropriate distance from the ball valve 4 and the push wheel 8. The stroke of the up and down movement of the lever 5 and the push wheel 8 plus the distance between the push wheel 8 and the roller 53 is equal to the diameter difference between the long diameter and the short diameter of the push wheel 8. The same diameter difference plus the movement trajectory can also design the push wheel 8 as a cam. The tension of the upward movement of one end of the lever 5 outside the base 1 is provided by the elastic component 9, and the downward movement is provided by the push wheel 8 pushing the roller 53 on the lever 5.

[0035] The motor 7 is disposed outside the base 1 and can be fixed on the brewing seat 6 (eg Figure 7As shown), the fixed position of the motor 7 is not limited. The brewing seat 6 can also be omitted, and the motor 7 can be set at other positions. The driving wheel 8 is connected to the motor 7, and the driving wheel 8 is driven by the motor 7. The motor 7 can be a micro motor, and the rotation stroke of the motor 7 is 0 to 180 degrees. The micro motor is preferably a stepping motor or a reduction motor. For example, the stepping motor has a step angle of 1.8 degrees. The 180-degree circular division positioning can be accurately adjusted according to the actual measurement requirements of the beverage brewing program. For example, a reduction motor is used, such as 10RPM, and the driving wheel 8 rotates 180 degrees in 3 seconds. The automatic control system can also use seconds (the decimal point can be one or two digits) for circular division positioning. Using a micro stepping motor or a reduction motor can make the initial instantaneous impact force of the driving wheel 8 driving the lever 5 to move more moderate, so that the relevant mechanism can have a longer service life. The electromagnet can also be used to drive the lever 5. The instantaneous impact force is too large, and it can only be fully opened or fully closed. The rotation of the micro motor can be reset to zero by the command of the automatic control system. Since the mechanical precision error may accumulate the error value, a positioning device can also be installed on the mechanism of the driving wheel 8. Since the positioning device has many options and is a prior art, it will not be described in detail.

[0036] like Figure 7 and Figure 8 As shown, first place the filter paper 10 on the filter cup 2, add a certain amount of ground coffee or tea and other ingredients, then place the filter cup 2 and the base 1 on the brewing seat 6, and the brewing seat 6 may be provided with a positioning ring 61, which fits exactly with the base 1, so that the filter cup 2 is positioned and the brewing (hand brewing) procedure is performed.

[0037] For the second embodiment, please refer to Fig. 9 In the present application, coffee is used as an example for brewing beverages. In order to evenly sprinkle hot water on the coffee powder during brewing, a water separator 20 with multiple water outlet holes 201 can be used. There are many water separators available in the market. The water separator 20 is set above the filter cup 2. When the filter paper 10 is properly installed in the filter cup 2, the filter paper 10 is usually higher than the upper end of the filter cup 2, so that the water separator 20 is not stable due to the obstruction of exceeding the filter paper 10. If the upper end of the filter cup 2 is designed to be slightly higher than the upper end of the filter paper 10, the water separator 20 can be placed on the filter cup 2, and a more stable effect can be obtained, which improves the disadvantage that the upper end of the existing filter cup is lower than the upper end of the filter paper, which hinders stable placement during use. After the coffee brewing process is completed, the filter paper 10 and coffee grounds need to be removed. A working hole 22 is set on both sides of the upper end of the filter cup 2. The working hole 22 is recessed in the upper end of the filter cup 2, which can be conveniently removed from the filter paper 10 for subsequent cleaning procedures.

[0038] For the third embodiment, please refer to Fig.10In this embodiment, the brewing seat 6 can also be changed to be placed above the filter cup 2. The brewing seat 6 is fixed in an appropriate position. The filter cup 2 is provided with a left-right symmetrical cup wing 23. The brewing seat 6 is provided with a positioning ring 62 symmetrical to the cup wing 23. The cup wing 23 can be snapped into the positioning ring 62, so that the filter cup 2 is easy to position for brewing.

[0039] For the fourth embodiment, please refer to Fig.11 , when brewing beverages, using filter paper has problems of hygiene, cost and inventory control, and using a filter screen can avoid this problem. In this embodiment, the filter cup 2 includes an outer cup 24, an inner cup 25 and a filter screen 26. The soup discharging mechanism at the bottom of the outer cup 24 is the same as the previous example. The outer diameter of the inner cup 25 is slightly smaller than the inner diameter of the outer cup 24 so that the inner cup 25 can be installed in the outer cup 24. The filter screen 26 is arranged at the bottom of the inner cup 25. The material of the filter screen 26 can be stainless steel or food-grade plastic. The mesh of the filter hole needs to be selected according to the coarseness of the grinding of the food and the brewing requirements. The selection of a single-layer filter screen 26 or a multi-layer filter screen 26 is selected to meet the beverage brewing requirements. The bottom of the outer cup 24 and the inner cup 25 corresponding to each other can have a bottom surface inclined toward the center to facilitate the flow of the soup. When executing the brewing program, a certain amount of food is placed in the inner cup 25, and the inner cup 25 is tapped by hand to make the food distribution more even, and the inner cup 25 is placed in the outer cup 24. After it is properly placed, the filter cup 2 is placed in the brewing position, and the brewing key (not shown in the figure) is pressed. The automatic control system executes the default brewing program. After the brewing program is completed, the filter cup 2 is first pulled out, and then the inner cup 25 is taken out to remove the food residue, and then the inner cup 25 and the outer cup 24 are cleaned to complete the beverage brewing program. When executing the brewing program, the hot water can be inlet by a water distributor or a spray nozzle or other uniform water inlet devices (not shown in the figure), which can evenly spray hot water on the food, and the hot water inlet method is not limited.

[0040] For the fifth embodiment, please refer to Fig.12 In this embodiment, if the brewing procedure only executes the opening or closing of the soup flow, the inner hole 31 of the ball valve chamber 3 can be set as a straight hole with an appropriate gap with the diameter of the ball valve 4, and the diameter of the outlet 32 ​​designed at the bottom of the ball valve chamber 3 is smaller than the diameter of the ball valve 4, so as to achieve smooth soup output and flow-stopping function. The driving wheel 8 rotates 180 degrees and returns to the 0 degree position, and the opening and closing function of the ball valve 4 is executed according to the beverage brewing procedure, that is, the beverage soaking or soup dispensing procedure is executed.
