Description

Technical Field

[0001] The utility model relates to a beverage brewing device, in particular to a bean grinding device and a coffee machine using the bean grinding device. Background Art

[0002] With the changes in people's living habits and the improvement of their quality of life, more and more people have begun to accept and love coffee as a drink, so various coffee machines for home use have begun to appear in people's lives.

[0003] Currently, commonly used coffee machines are usually equipped with a bean grinding device. For ease of use, the bean hopper of the bean grinding device is usually openable and closable. For example, Chinese patent application number 202323303141.4 discloses a bean hopper structure for a coffee machine, which includes a bean hopper body and a bean hopper connecting base. The bean hopper connecting base is provided with a slide rail on the top, and a slider that cooperates with the slide rail is provided at the bottom of the bean hopper body. The slider is provided with a bean outlet. Two blocking plates are symmetrically provided at the bean outlet. One end of the blocking plate extends to form a connecting ear. The connecting ear is rotatably connected to the bottom of the bean hopper body via a rotating shaft. The rotating shaft is also provided with a torsion spring. Two vertical blocking rods are fixed to the bottom of the slide rail. The connecting ear on the baffle extends outward to form a boss. When the bean hopper body cooperates with the slide rail, the blocking rod pushes the boss to rotate the baffle outward to open the bean outlet. When the bean hopper body is disengaged from the slide rail, the blocking plate blocks the bean outlet under the action of the torsion spring.

[0004] Typically, in existing coffee machines, the motor of the grinding assembly can be started when the bean hopper assembly and the grinding assembly are in place. However, if the bean hopper is closed at this time, the motor will idle, resulting in unnecessary energy waste.

[0005] Therefore, there is room for further improvement. Utility Model Content

[0006] The first technical problem to be solved by the present invention is to provide a bean grinding device to avoid the misstart of the bean grinding motor in view of the above-mentioned deficiencies in the prior art.

[0007] The second technical problem to be solved by the present invention is to provide a coffee machine using the above-mentioned bean grinding device.

[0008] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: a bean grinding device, comprising:

[0009] a bean silo assembly comprising a bean silo having an outlet that can be opened and closed; and

[0010] A bean grinding assembly, comprising a main unit and a bean grinding box mounted on the main unit, wherein the main unit comprises a motor and a micro switch capable of controlling the motor; characterized in that:

[0017] Fourth state: the bean hopper is open, the bean grinding box is installed in place on the main unit, the slide bar is pushed upward and has a lateral displacement relative to the initial position, and the slide bar contacts the micro switch and triggers the micro switch.

[0018] By setting up a trigger component to cooperate with the bean hopper and grinder box respectively, the micro switch can be triggered by the trigger component only when the bean hopper is open and the grinder box is in place, thereby transmitting a start signal to the motor, avoiding the erroneous operation of starting the motor when the bean hopper and grinder box are not ready.

[0019] In order to enable the bean hopper outlet state to cooperate with the first trigger block, the bean hopper assembly includes a baffle disposed in the bean hopper and capable of sliding relative to the bean hopper, wherein the baffle can open and close the bean hopper outlet;

[0020] The bean bin assembly further includes a top rod and a connecting rod, wherein the top rod maintains a tendency to be retracted in the bean bin, and the connecting rod is slidably disposed in the bean bin;

[0021] When the bean bin is closed, the top rod is retracted into the bean bin;

[0022] When the bean bin is opened, the baffle pushes the top rod through the bean bin via the connecting rod and contacts the first trigger block, so that the first trigger block has a lateral displacement relative to the initial position.

[0023] Preferably, the bean bin comprises a box body, a top cover and a bottom cover, the top cover is arranged on the top of the box body, the bottom cover is arranged on the bottom of the box body, the baffle is slidably placed on the bottom cover, and the outlet is formed on the bottom cover.

[0024] In order to facilitate the definition of the trajectory of the top rod and the connecting rod, the bean bin further includes a base, the base is arranged in the box body, and the baffle is located between the base and the bottom cover;

[0025] The top rod is at least partially arranged in the base, one end of the top rod is rotatably connected to the base, and the other end of the top rod can pass through the bean bin; the connecting rod is limited by the base and moves linearly, and the top rod partially passes through the base and contacts the connecting rod.

[0026] In order to ensure that the installation state of the bean grinding box can cooperate with the second trigger block, the main unit further includes a bottom plate, the bean bin is supported on the bottom plate, and the bean grinding box is installed below the bottom plate. The bean grinding box includes a box body and a top block arranged on the top of the box body. When the bean grinding box is installed in place, the top block pushes the second trigger block upward.

[0027] Preferably, one side of the bean hopper is concave, and the main unit further includes a bean hopper bracket, a bottom plate and a mounting shell, the bean hopper bracket and the mounting shell are located in the concave position, the bean hopper is supported on the bottom plate, the bean grinding box is mounted under the bottom plate, the mounting shell extends upward from the bottom plate and is arranged in parallel with the bean hopper bracket, the motor is mounted in the bean hopper bracket, and the micro switch is arranged in the mounting shell.

[0028] In order to facilitate the definition of the trajectory of the first trigger block and the second trigger block, the mounting shell is open on one side away from the bean hopper support. The main body of the bean grinding assembly further comprises a back plate, which is fixedly arranged at the opening of the mounting shell. The first trigger block and the second trigger block are both slidably engaged with the back plate.

[0029] To facilitate the resetting of the first trigger block, the trigger assembly also includes a first elastic member, which is a torsion spring installed in the mounting shell. The two ends of the first elastic member are respectively in contact with the first trigger block and the mounting shell, thereby maintaining the tendency of the first trigger block to reset.

[0030] To facilitate the resetting of the second trigger block, the trigger assembly also includes a second elastic member, which is a spring sleeved on the slide rod. The upper end of the second elastic member abuts against the first trigger block, and the lower end of the second elastic member remains relatively fixed to the slide rod.

[0031] The technical solution adopted by the present invention to solve the second technical problem is: a coffee machine, including a machine body, characterized in that the bean grinding device as described above is installed on the machine body.

[0032] Compared with the prior art, the advantages of the present invention are as follows: by providing a trigger assembly that cooperates with the bean hopper and the grinder box respectively, the micro switch can be triggered by the trigger assembly only when the bean hopper is in the open state and the grinder box is in place, thereby transmitting a start signal to the motor, thereby avoiding the erroneous operation of starting the motor when the bean hopper or the grinder box is not ready.

[0052] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions.

[0053] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present invention can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0054] See also Figures 1 to 10 A coffee machine includes a machine body 200 and a bean grinding device 100 disposed outside the machine body 200. The bean grinding device 100 is entirely removable and installable relative to the machine body 200. The bean grinding device 100 includes a bean hopper assembly 1 and a bean grinding assembly 2, and the bean hopper assembly 1 and the bean grinding assembly 2 are removably installed. The bean hopper assembly 1 is used to store coffee beans, and the bean grinding assembly 2 is used to grind the coffee beans into coffee powder.

[0055] The bean hopper assembly 1 includes a bean hopper 11, a baffle 12, a lever 13, a top rod 14, and an elastic rod 15, and the bean grinding assembly 2 includes a main unit 21 and a bean grinding box 22. The bean hopper 11 includes a housing 111, a top cover 112, a bottom cover 113, and a base 114. The top cover 112 is located on the top of the housing 111, and the bottom cover 113 is located on the bottom of the housing 111, thereby forming a space inside the housing 111 for accommodating coffee beans. The base 114 is located within the housing 111 and can be tightly mounted on the bottom cover 113. The base 114 and the bottom cover 113 can be fixed together by screws. The coffee beans are accommodated in the space above the base 114, and the coffee beans can be added by opening the top cover 112.

[0056] The housing 111 has two opposing sides. The first side (the rear side facing away from the user when in use), i.e., the side facing the coffee machine body 200, is recessed away from the body 200 to accommodate a portion of the main unit 21. The main unit 21 includes a motor 211, a bean hopper support 212 disposed around the periphery of the motor 211, and a bottom plate 213 disposed beneath the bean hopper support 212. The bean hopper support 212 of the main unit 21 is recessed into a recessed position at the rear side of the housing 111, while the bottom plate 213 is located below the bottom of the bean hopper 11. The grinding box 22 includes a housing 221, a dynamic grinding wheel 222, and a static grinding wheel (not shown, as in the prior art). The output shaft of the motor 211 is connected to a first transmission shaft 2111, which extends below the bottom plate 213. The dynamic grinding wheel 222 is provided with a second transmission shaft 223. The first transmission shaft 2111 and the second transmission shaft 223 are in driving connection, enabling the motor 21 to drive the dynamic grinding wheel 222 to rotate.

[0057] The bottom cover 113 has a first through-hole 1131 for coffee beans to pass through, serving as an outlet for the bean hopper 11. A second through-hole 2131 is provided on the bottom plate 213 of the main unit 21 of the grinding assembly 2, corresponding to the first through-hole 1131. The top of the grinding box 22 is open, and in horizontal projection, the second through-hole 2131 falls within the range of the open top of the grinding box 22, allowing coffee beans to pass through the second through-hole 2131 and enter the grinding box 22. A third through-hole 1141 is provided on the base 114, corresponding to the first through-hole 1131, allowing coffee beans to pass downward from the space within the housing 111 and reach the first through-hole 1131 on the bottom cover 113.

[0058] A through-hole 1111 is defined on a second side of the housing 111 (the front side facing the user when in use), i.e., the side facing away from the coffee machine body 200. The lever 13 extends from the outside of the housing 111 through the through-hole 1111 and into the interior of the housing 111. The baffle 12 is slidably disposed on the bottom cover 113, located between the base 114 and the bottom cover 113 (the base 114 is recessed upward at a position corresponding to the baffle 12). The portion of the lever 13 that extends into the housing 111 is connected to the baffle 12. The lever 13 and baffle 12 can be separate components connected to each other, or they can be integrally formed. Thus, by operating the lever 13 from outside the bean hopper 11, it slides along the through-hole 1111, thereby driving the baffle 12 to slide. The sliding of the baffle 12 opens and closes the first through-hole 1131, thereby opening the bean hopper 11 to allow coffee beans to pass through, or closing the bean hopper 12 to prevent coffee beans from passing through. In this embodiment, the sliding direction of the baffle 12 is perpendicular to the direction of the line connecting the first side and the second side of the box body 111, that is, the left and right direction of the user when in use. Figure 2 The Z-axis direction shown in FIG, the sliding direction of the baffle 12 is the X-axis direction, and the Y-axis direction is the up-down direction. Alternatively, the baffle 12 can also slide along the Z-axis or other directions, as long as it can cooperate with the bottom cover 113 to open (see FIG Figure 14 ) and close bean bin 11 (see Figure 9 、 Figure 10 ) can be used.

[0059] The baffle 12 includes a baffle body 121 and a bean outlet hole 123 formed therein. The bean outlet hole 123 and the first perforation 1131 preferably correspond in size and shape. Thus, when the baffle 12 slides until the bean outlet hole 123 aligns with the first perforation 1131, the first perforation 1131 opens. When the baffle 12 slides until the bean outlet hole 123 and the first perforation 1131 are misaligned, the first perforation 1131 closes. Alternatively, the bean outlet hole 123 may be omitted. By properly sizing the baffle body 121, the first perforation 1131 can be opened and closed by sliding within the limited space within the housing 111.

[0060] See also Figure 9 、 Figure 10 and Figure 14The top rod 14 may be at least partially disposed within the base 114, with one end of the top rod 14 rotatably connected to the base 114, and the other end of the top rod 14 extending out of the bean hopper 11. An elastic rod 15 is disposed adjacent to the top rod 14, with one end of the elastic rod 15 being fixed to the base 114 or the bottom cover 113 and the other end being connected to the top rod 14, thereby maintaining a tendency for the top rod 14 to be retracted into the bean hopper 11. The bean hopper 11 also includes a connecting rod 16 slidably disposed within the base 114. The connecting rod 16 may be limited by the base 114 so that the connecting rod 16 can only move linearly in one direction. The connecting rod 16 may be opposite the bottom cover 113, while the top rod 14 and the elastic rod 15 are disposed on a side of the base 14 away from the bottom cover 113. The top rod 14 may partially extend through the base 114, thereby causing the top rod 14 and the connecting rod 114 to interfere with each other. When the connecting rod 16 moves, it can push the top rod 14 to rotate relative to the base 114, so that the free end of the top rod 14 (the end not connected to the base 114) is extended out of the bean bin 11.

[0061] In order to facilitate the movement of the connecting rod 16, the baffle 12 can be used. When the baffle 12 slides to the closed position, it does not contact the connecting rod 16, and the top rod 14 retracts into the bean bin 11. Figures 10 to 13 When the baffle 12 slides to the open position, it contacts the connecting rod 16, thereby pushing the connecting rod 16 to move. Figures 14 to 17 ,in Figure 15 The middle arrow A indicates the moving direction of the connecting rod 16, which in turn pushes the top rod 14 to rotate, so that the end of the top rod 14 passes out of the bean bin 11. Figure 15 The middle arrow B shows the rotation direction of the push rod 14. After this, the baffle 12 slides to the closed position again, and the connecting rod 16 is no longer stressed. The push rod 14 is reset under the effect of the elastic rod 15 and pushes the connecting rod 16 to reset.

[0062] Recombination Figure 7 and Figure 8 The main unit 21 of the bean grinding assembly 2 also includes a microswitch 216, which transmits signals to the control module of the main unit 21, thereby controlling the operation of the motor 211. Optionally, the microswitch 216 is located on the rear side of the bean hopper support 212. The main unit 21 of the bean grinding assembly 21 also includes a mounting housing 218, which is located on the rear side of the bean hopper support 212 and is arranged in parallel with the bean hopper support 212 within the recess of the bean hopper 11. The mounting housing 218 can be integrally formed with the bottom plate 213, extending upward from the rear side of the bottom plate 213. The microswitch 216 is disposed within the mounting housing 218.

[0063] The main body 21 of the grinding assembly 2 also includes a backplate 217, which is fixedly mounted on the rear opening of the mounting housing 218. The grinding assembly 2 also includes a trigger assembly, comprising a first trigger block 231, a second trigger block 232, and a slide rod 233. The backplate 217 is mounted on the rear side of the trigger assembly. The first trigger block 231 is positioned above the second trigger block 232. The bottom of the slide rod 233 abuts the top of the second trigger block 232, and the slide rod 233 extends upward through the first trigger block 231. The first trigger block 231 is adapted to engage with the ejector rod 14. When the ejector rod 14 extends, it pushes the first trigger block 231 to move along the X-axis. A top block 224 is provided on the top of the grinding box 221. This top block 224 engages with the bottom of the second trigger block 232, and when the grinding box 22 is installed, it pushes the second trigger block 232 upward.

[0064] The first trigger block 231 and the second trigger block 232 can both be slidably engaged with the back plate 217 , thereby limiting the movement paths of the first trigger block 231 and the second trigger block 232 via the back plate 217 . The slide bar 233 can only slide up and down relative to the first trigger block 231 .

[0065] To facilitate the resetting of the first and second trigger blocks 231, the trigger assembly further includes a first elastic member 234 and a second elastic member 235. The first elastic member 234 may be a torsion spring mounted within the mounting housing 218. The two ends of the torsion spring abut against the first trigger block 231 and the mounting housing 218, respectively, thereby maintaining the tendency of the first trigger block 231 to reposition (closer to the push rod 14). The second elastic member 235 may be a spring mounted on the slide bar 233. The upper end abuts against the first trigger block 231, while the lower end remains relatively fixed to the slide bar 233, thereby maintaining the tendency of the slide bar 233 to slide downward.

[0066] Thus, the bean grinding device 100 can be in the following four states: 1) State 1: See Figure 13 , the first trigger block 231 and the second trigger block 232 are not lifted (the bean hopper 11 is not installed in place or installed in place but not opened, the grinding box 22 is not installed in place), in the initial position, the micro switch 216 is not triggered, and the motor 211 cannot work; 2) State 2: See Figure 16 , the bean hopper 11 is installed in place and opened, the first trigger block 231 is pushed up by the push rod 14 (moved horizontally to the right relative to state 1, "right" only indicates the perspective shown in the figure), and the second trigger block 232 is not pushed up (the grinding box 22 is not installed in place), so the slide bar 233 is not pushed up, the micro switch 216 is not triggered, and the motor 211 cannot work; 3) State 3: See Figure 18The bean hopper 11 is not installed in place or is installed in place but not opened, the first trigger block 231 is not lifted, the bean grinding box 22 is installed in place, the second trigger block 232 is lifted, and the slide bar 233 is lifted upward, but is laterally misaligned with the contact 2161 of the micro switch 216 and does not contact it. The micro switch 216 is not triggered, and the motor 211 cannot work; 4) State 4: See Figure 19 , the bean hopper 11 is installed in place and opened, the first trigger block 231 is lifted by the push rod 14, and the first trigger block 231 drives the slide bar 233 to move to the right ("right" only indicates the perspective shown in the figure). The bean grinding box 22 is installed in place, the second trigger block 232 is lifted, and the slide bar 233 is pushed upward, thereby the slide bar 233 contacts the contact 2161 of the micro switch 216, the micro switch 216 is triggered, and the motor 211 can operate.
