DETAILED DESCRIPTION

[0041] The specific implementation of the present invention will be described below with reference to the accompanying drawings.

[0042] As a specific embodiment, the coffee machine of the embodiment of the present invention includes a coffee machine body 1. The coffee machine body 1 is a device for making coffee in the prior art, and its internal structure will not be described in detail.

[0043] The coffee machine of this embodiment also includes a bean container assembly 2. The coffee machine body 1 is provided with a bean inlet 11. The bean container assembly 2 is used to pre-load coffee beans. When connected to the coffee machine body 1, the bean container assembly 2 transfers the coffee beans from the bean inlet 11 into the coffee machine body 1, where the coffee beans are ground and processed.

[0044] The bean container assembly 2 includes a container member 21 and a container seat assembly 22 .

[0045] The container seat assembly 22 includes a container seat 23 , a synchronous direction-changing member 25 and a plurality of control doors 24 .

[0046] The synchronous direction-changing member 25 is rotatably connected to the container seat 23 and / or the container member 21 around a bottom opening (not shown in the drawings) of the container member 21. For example, the synchronous direction-changing member 25 is generally disc-shaped and fits against the inner sidewall of the container seat 23, thereby enabling the synchronous direction-changing member 25 to be rotatably connected to the container seat 23.

[0047] The control door 24 is connected to the container seat 23 in a linear sliding manner in a direction pointing toward the center hole of the container seat 23 (not shown in the drawings); for example, the container seat 23 is provided with a linear slide groove 231, and the control door 24 is inserted into the linear slide groove 231 to achieve a linear sliding connection between the control door 24 and the container seat 23. One of the synchronous direction-changing member 25 and the control door 24 is provided with a direction-changing groove 251, and the other of the synchronous direction-changing member 25 and the control door 24 is provided with a direction-changing abutment 241 inserted into the direction-changing groove 251. The direction-changing groove 251 moves in a circumferential direction (i.e., a direction rotating around the bottom opening of the container member 21) to move closer to or away from the bottom opening of the container member 21. For example, when viewed from above, the direction-changing groove 251 is generally arc-shaped or straight.

[0048] The container seat 23 is fixedly connected to the container member 21. For example, a connecting post 219 is provided at the bottom end of the container member 21. The connecting post 219 passes through a connecting post avoidance hole 259 of the synchronous direction-changing member 25 described later and is fixedly connected to the container seat 23 by screws, thereby fixing the container seat 23 to the container member 21.

[0049] It's easy to understand that the bottom opening of container 21, the center hole of the synchronous direction-changing member 25 (described later), and the center hole of container seat 23 are all aligned, allowing the coffee beans in container 21 to pass through the bottom opening of container 21, the center hole of the synchronous direction-changing member 25 (described later), and the center hole of container seat 23. As is conventional practice, the cross-sectional area of ​​the inner cavity of container 21 decreases from top to bottom (for example, the inner cavity of container 21 may be bowl-shaped, hemispherical, or truncated cone-shaped). This causes the coffee beans in container 21 to tend to move toward the bottom opening of container 21 due to their own weight.

[0050] The working principle is that before use, coffee beans (not shown in the drawings) are loaded into the inner cavity of the container 21. Due to their own weight, the coffee beans tend to enter the bottom opening of the container 21, but at this time the control door 24 blocks the bottom opening of the container 21, preventing the coffee beans from passing through.

[0051] The bean container assembly 2 is installed to the coffee machine body 1 in the manner described below; then the container part 21 is rotated so that the container seat 23 rotates relative to the synchronous direction-changing part 25 (for example, by plugging the synchronous direction-changing part 25 to the coffee machine body 1 temporarily, or by the structure of the rotation port 252 and the rotation support body 262 described below), and the direction-changing groove 251 abuts the direction-changing support body 241 so that the control door 24 slides linearly away from the bottom opening of the container part 21 until the bottom opening of the container part 21 is fully opened, and the coffee beans are ground and processed through the bean inlet 11.

[0052] Coffee beans have a relatively large particle size. However, since the bottom opening of the container member 21 is a single unit rather than multiple units, the coffee beans can easily pass through the bottom opening of the container member 21 under the premise that the total area of ​​the bottom opening of the container member 21 is constant. In addition, when the control door 24 is opened, the control door 24 moves away from the control door 24, making it difficult for the coffee beans to get stuck. In other words, it can be ensured that the coffee beans in the bean container assembly 2 can smoothly enter the bean inlet 11.

[0053] As one of the specific implementations, there are three or more control doors 24, one end of the control door 24 is a triangle, and the vertex angle of the triangle at one end of the control door 24 is 360 degrees divided by the number of the control doors 24. Figure 10 As shown, for example, there are three control doors 24 , and the vertex angle of the triangle at one end of the control door 24 is 120 degrees. The direction-changing grooves 251 are evenly distributed around the bottom opening of the container 21 .

[0054] As one specific embodiment, the triangular side of one end of the control door 24 (the side of the vertex of the triangle at one end of the control door 24) is provided with an end bevel 242. When the control door 24 is closed, adjacent triangular sides of the control door 24 form a triangular groove. This triangular groove stabilizes the posture of coffee beans that fall onto the control door 24, facilitating the entry of coffee beans into the bean inlet 11 when the control door 24 is opened.

[0055] As one of the specific implementation methods, Figure 6 As shown, a buffer cover 218 is provided within the inner cavity of the container 21. A vertical gap exists between the buffer cover 218 and the bottom opening of the container 21. When viewed from above, the bottom opening of the container 21 is completely within the buffer cover 218. The buffer cover 218 acts as a buffer when coffee beans are poured into the container 21. The coffee beans then enter the bottom opening of the container 21 through the gap between the buffer cover 218 and the container 21. This prevents excessive coffee beans from being squeezed against each other and becoming stuck in the bottom opening of the container 21. It also prevents fingers from directly entering the bean inlet 11 (e.g., being cut by a grinder), making the bean inlet safer.

[0056] As one specific embodiment, the coffee machine further includes a carrier connecting ring 26 for connecting to the coffee machine body 1. The carrier connecting ring 26 is disposed between the container member 21 and the synchronous direction-changing member 25. The carrier connecting ring 26 is rotatably connected to the container seat 23 and / or the container member 21 about the bottom opening of the container member 21. Without affecting the rotation of the container member 21, the carrier connecting ring 26, in conjunction with the safety structure 3 described below, can enhance safety. It will be readily understood that although the carrier connecting ring 26 and the synchronous direction-changing member 25 are both rotatably connected to the container seat 23 and / or the container member 21 about the bottom opening of the container member 21, the carrier connecting ring 26 and the synchronous direction-changing member 25 are not fixed to each other and can rotate relative to each other.

[0057] As one specific embodiment, the carrier connecting ring 26 is provided with a fixing protrusion 263, which is used to be inserted into the coffee machine body 1 and connect the carrier connecting ring 26 to the coffee machine body 1; and / or the container seat 23 is provided with a rotating protrusion 233, which is used to be inserted into the coffee machine body 1 and connect the container seat 23 to the coffee machine body 1. In conjunction with the safety structure 3 described below, safety can be improved.

[0058] As one specific embodiment, the carrier connecting ring 26 is generally annular in shape. The container member 21 is provided with a guide edge 216 that abuts against the outer wall of the carrier connecting ring 26. The bottom end of the carrier connecting ring 26 abuts against the container seat 23. This facilitates assembly of the bean container assembly 2 while enabling rotational connection of the carrier connecting ring 26 and sealing between the carrier connecting ring 26 and the container member 21.

[0059] As one specific embodiment, one of the carrier connecting ring 26 and the synchronous direction-changing member 25 is provided with a gear abutment 254, and the other of the carrier connecting ring 26 and the synchronous direction-changing member 25 is provided with an elastic gear abutment 264. The elastic gear abutment 264 can abut against the gear abutment 254. When a person holds the bean container assembly 2 and operates the bean container assembly 2 on the coffee machine body 1, the elastic gear abutment 264 abuts against the gear abutment 254, causing the elasticity of the elastic gear abutment 264 to bounce and vibrate, thereby providing feedback to the person, such as gear position information, such as the bean container assembly 2 being rotated into position.

[0060] As one of the specific embodiments, one of the carrier connecting ring 26 and the synchronous direction-changing member 25 is provided with a rotation-supporting body 262, and the other of the carrier connecting ring 26 and the synchronous direction-changing member 25 is provided with a rotation-supporting opening 252. The rotation-supporting body 262 can support the side wall of the rotation-supporting opening 252, and the central angle corresponding to the rotation-supporting body 262 is smaller than the central angle corresponding to the rotation-supporting opening 252 (when viewed from above, the angle between the two lines connecting the two side walls of the rotation opening 252 and the center of the bottom opening of the container member 21 is also the central angle of the rotation-supporting body 262). The rotation-supporting body 262 supports the side wall of the rotation opening 252, so that the carrier connecting ring 26 and the synchronous direction-changing member 25 rotate synchronously. However, when there is no support between the rotation-supporting body 262 and the side wall of the rotation opening 252, the carrier connecting ring 26 can rotate relative to the synchronous direction-changing member 25, and the safety structure 3 described later can improve safety.

[0061] As one of the specific embodiments, the bean container assembly 2 further includes a container cover 29 that covers the top opening of the container 21 and is detachably connected to the container 21 .

[0062] The coffee machine body 1 further includes a safety structure 3 .

[0063] The safety structure 3 includes a fixed bean inlet ring 31, a rotating bean inlet ring 32, and a safety switch 33 capable of controlling the coffee machine body 1. The safety switch 33 is a conventional contact sensor, such as a micro switch, which is used to control the motor (not shown) in the coffee machine body 1 for grinding coffee beans.

[0064] The bean inlet fixing ring 31 is fixed relative to the coffee machine body 1. For example, the bean inlet fixing ring 31 is integrally injection-molded with the top cover 41 described later and fixed relative to the coffee machine body 1.

[0065] The bean inlet rotating ring 32 is used to connect with the bean container assembly 2, for example, by inserting the rotating protrusion 233 described later into the container seat rotating groove 323 to achieve the connection.

[0066] The bean inlet rotating ring 32 is in the shape of a circular ring and can rotate around the bean inlet 11 relative to the coffee machine body 1. When viewed from above, the bean inlet 11 is completely located within the bean inlet fixed ring 31 and the bean inlet rotating ring 32. It is easy to understand that coffee beans can pass through the bean inlet fixed ring 31 and the bean inlet rotating ring 32 and pass through the bean inlet 11.

[0067] The bean inlet rotating ring 32 is provided with a trigger flange 321. The safety switch 33 is fixedly connected to the coffee machine body 1 and is located in the rotation path of the trigger flange 321 (rotating along with the bean inlet rotating ring 32). For example, the safety switch 33 is fixed to the bottom end surface of the top cover member 41 described below.

[0068] The operating principle is as follows: the bean container assembly 2 is installed at the bean inlet 11 of the coffee machine body 1, so that the bean container assembly 2 is connected to the bean inlet rotating ring 32. The bean container assembly 2 is then rotated, causing the bean container assembly 2 to rotate the bean inlet rotating ring 32 until the rotating protrusion 233 triggers the safety switch 33 and controls the coffee machine body 1. For example, the safety switch 33 is a normally open microswitch connected in series with the power cord of the coffee bean grinding motor. Only when the rotating protrusion 233 triggers the safety switch 33 can the coffee bean grinding motor, etc., be activated. Conversely, if the bean container assembly 2 is not installed at the bean inlet 11 of the coffee machine body 1, the safety switch 33 cannot activate the coffee bean grinding motor, etc., and even if a person reaches into the bean inlet 11, they will not be injured, thus improving safety.

[0069] As one specific embodiment, the bean inlet rotating ring 32 further includes a rotational locking member 34. The bean inlet rotating ring 32 is provided with an unlocking hole 324. The rotational locking member 34 includes an unlocking portion 341 that passes through the unlocking hole 324. The bean inlet fixed ring 31 is provided with a locking groove 314. The rotational locking member 34 is vertically and linearly connected to the bean inlet rotating ring 32 and tends to approach and engage with the locking groove 314. When the rotational locking member 34 engages with the locking groove 314, the bean inlet rotating ring 32 is locked and prevented from rotating, maintaining its position, facilitating installation of the bean container assembly 2 at the bean inlet 11 of the coffee machine body 1. When the bean container assembly 2 is installed at the bean inlet 11 of the coffee machine body 1, the container seat 23 abuts against the unlocking portion 341, causing the rotational locking member 34 to move downward and disengage from the locking groove 314. At this point, the bean inlet rotating ring 32 is unlocked and can rotate, triggering the safety switch 33, thereby enhancing safety.

[0070] As one specific embodiment, the bean inlet rotating ring 32 is provided with a locking member slot 325. The rotating locking member 34 engages in the locking member slot 325, thereby enabling a vertically linear sliding connection between the rotating locking member 34 and the bean inlet rotating ring 32. For example, a snap-fit ​​structure (not shown) provided on the inner sidewall of the locking member slot 325 can prevent the rotating locking member 34 from disengaging from the locking member slot 325. This facilitates assembly of the bean inlet rotating ring 32 and the locking member slot 325.

[0071] As one specific embodiment, the rotary locking member 34 is provided with a spring column 348, which is fitted with a spring-loaded locking elastic member 349. The two ends of the locking elastic member 349 respectively abut against the bean inlet rotating ring 32 (the portion of the bean inlet rotating ring 32 abutting against the locking elastic member 349 is not shown; this portion may be an L-shaped cross-section) and the rotary locking member 34, so that the rotary locking member 34 is close to the locking groove 314. This facilitates assembly of the bean inlet rotating ring 32 and the locking member sliding groove 325.

[0072] As one of the specific embodiments, the bean inlet fixed ring 31 is provided with a connecting ring fixing groove 313, and the bean inlet rotating ring 32 is provided with a container seat rotating groove 323, and the container seat rotating groove 323 is located below the connecting ring fixing groove 313. By moving the bean container assembly 2 downward, the fixing protrusion 263 can be inserted into the connecting ring fixing groove 313 and the rotating protrusion 233 can be embedded in the container seat rotating groove 323. Then, the container part 21 is manually rotated. During the rotation of the container part 21, the fixing protrusion 263 is abutted by the inner wall of the connecting ring fixing groove 313 and is restricted from rotating. However, the bean inlet rotating ring 32 allows the rotating protrusion 233 of the container seat 23 to drive the bean inlet rotating ring 32 to rotate (the rotation of the bean inlet rotating ring 32 can simultaneously trigger the safety switch 33); until the aforementioned rotating abutting body 262 abuts Along with the inner wall of the rotating opening 252, the synchronous changing member 25 rotates relative to the container seat 23 to open the control door 24. In other words, it is possible to control the control door 24 of the bean container assembly 2 and the safety switch 33 of the safety structure 3 without having to operate them separately, which can simplify the operation of installing the bean container assembly 2 on the bean inlet 11 of the coffee machine body 1; the safety switch 33 can only be triggered after the control door 24 is opened and the coffee beans enter the coffee machine body 1 through the bean inlet 11, which can prevent the motor used for grinding beans from idling, thereby improving the reliability of the equipment.

[0073] As one specific embodiment, the container seat rotation groove 323 is aligned with the connecting ring fixing groove 313 (this alignment is not shown in the accompanying drawings; alignment means that the side walls of the two completely overlap when viewed from above, but the arc side walls do not necessarily need to be aligned; in other words, the central angles of the two circles are the same, but the radii can be different). The rotating protrusion 233 of the container seat 23 is also aligned with the fixing protrusion 263 of the carrier connecting ring 26. When installing the bean container assembly 2 to the bean inlet 11 of the coffee machine body 1, the bean container assembly 2 is moved downward so that the fixing protrusion 263 engages with the connecting ring fixing groove 313 and the rotating protrusion 233 engages with the container seat rotation groove 323, thereby facilitating installation of the bean container assembly 2 to the bean inlet 11 of the coffee machine body 1.

[0074] As one specific embodiment, when the container seat rotation groove 323 is aligned with the connecting ring fixing groove 313, the rotation locking member 34 engages with the locking groove 314. When the bean container assembly 2 is installed at the bean inlet 11 of the coffee machine body 1, the bean container assembly 2 is moved downward so that the fixing protrusion 263 is inserted into the connecting ring fixing groove 313 and the rotation protrusion 233 is inserted into the container seat rotation groove 323. The container seat 23 then abuts against the rotation locking member 34 to unlock the bean container. After the bean container assembly 2 is rotated in the opposite direction and removed, the container seat rotation groove 323 is aligned with the connecting ring fixing groove 313, and the unlocking portion 341 of the rotation locking member 34 is no longer abutted by the container seat 23, returning to its original position and engaging with the locking groove 314. This ensures that the container seat rotation groove 323 is aligned with the connecting ring fixing groove 313 each time the bean container assembly 2 is installed in the coffee machine body 1, eliminating the need to adjust the rotation angle of the bean inlet rotating ring 32 relative to the bean inlet fixing ring 31, resulting in a more convenient installation.

[0075] The coffee machine body 1 includes a top cover structure 4 and a carrier 9, which together form a cavity. This cavity is used to house components used for coffee production, such as the aforementioned motor for grinding coffee beans. The carrier 9 includes a front support 91 and side inner walls 92. As will be readily understood, there are two side inner walls 92, one located on the left and one on the right of the front support 91.

[0076] The top end of the front carrier 91 extends to form an inner extension body 911 .

[0077] The top cover structure 4 includes a top cover member 41 and a top cover frame 42 .

[0078] An upper abutting edge 411 and a lower abutting edge 412 are provided at the front end of the top cover 41 .

[0079] The roof frame 42 includes a front beam 421 and side beams 422 , so that the roof frame 42 is U-shaped as a whole.

[0080] The front beam 421 is detachably connected to the inner extension body 911 . The upper abutting edge 411 abuts against the top end of the front beam 421 , and the lower abutting edge 412 abuts against the bottom end of the inner extension body 911 .

[0081] The working principle is that although Figure 16-18 The front-end carrier 91 is drawn separately, but it is easy to understand that the front-end carrier 91 is a part of the carrier 9.

[0082] During assembly, the front beam 421 of the top cover frame 42 is connected to the front end carrier 91, and then the top cover member 41 is moved toward the front beam 421 and the inner extension body 911 with the rear end higher and the front end lower. First, the lower supporting edge 412 is abutted against the inner extension body 911, and then the rear end of the top cover member 41 is moved downward until the upper supporting edge 411 abuts against the top end of the front beam 421, and the lower supporting edge 412 abuts against the bottom end of the inner extension body 911. That is, the top cover structure 4 can be easily and quickly assembled to the carrier 9 of the coffee machine body 1.

[0083] As one specific embodiment, the inner extension body 911 is provided with a front snap hole 912; the front beam 421 is provided with a front beam snap 423 and a front beam positioning body 424. The front beam snap 423 passes through the front snap hole 912 and abuts against the bottom end of the inner extension body 911, and the front beam positioning body 424 fits against the inner wall of the front snap hole 912, thereby allowing the front beam 421 to be detachably connected to the inner extension body 911. This facilitates the detachable connection of the front beam 421 to the inner extension body 911 while ensuring accurate front-to-back alignment between the front beam 421 and the inner extension body 911.

[0084] As one specific embodiment, the side beam 422 is provided with a side inner wall fixing ear 429; the side inner wall fixing ear 429 is fixedly connected to the side inner wall 92, for example, by screws passing through the side inner wall fixing ear 429 and screwing into the side inner wall 92, thereby ensuring the connection strength between the top cover structure 4 and the carrier 9.

[0085] As one of the specific implementations, the top cover 41 is provided with a side beam buckle 413, and the side beam buckle 413 is buckled and connected to the side beam 422. This can ensure that the top cover 41 and the side beam 422 are tightly connected without any gap.

[0086] As one specific embodiment, one of the side beam 422 and the top cover 41 is provided with an anti-sway body 415 arranged along the side beam 422, and the other of the side beam 422 and the top cover 41 is provided with an anti-sway groove 425, into which the anti-sway body 415 fits. This ensures accurate left-right alignment between the side beam 422 and the top cover 41.

[0087] As one specific embodiment, the outer casing 49 is further provided with a covering ear 491 on its edge. The covering ear 491 passes through the top cover 41 and / or the top cover frame 42 and is then bent (the bent covering ear 491 is not shown), thereby ensuring that the outer casing 49 is snugly and fixedly connected to the top cover 41 and the top cover frame 42. Typically, the outer casing 49 and the covering ear 491 thereon are made of sheet metal or the like and are integrally formed. This improves the waterproofness of the top cover structure 4 while also enhancing the overall strength of the top cover structure 4.
