Description

Technical Field

[0001] This utility model relates to the field of beverage brewing equipment technology, specifically to a bean hopper valve structure for a coffee grinder. Background Technology

[0002] A coffee grinder is a grinding tool that cuts and grinds coffee beans into coffee powder when a motor drives mechanical blades to rotate at high speed. Coffee grinding is usually carried out inside the grinding chamber.

[0003] Most coffee grinders on the market currently lack a bean-locking function. When using them, if you need to stop midway to remove the remaining coffee beans, you have to lift the entire machine to pour the beans out of the bean hopper, which is very inconvenient. To address this, Chinese patent application CN202222897765.2, entitled "A Simple Bean-Locking Component and a Coffee Grinder with the Component," discloses a simple bean-locking component, including a bean hopper and a rotating assembly. The rotating assembly is rotatably connected to the bean hopper. The rotating assembly has a bean-dropping channel, and the bean hopper has a downward sliding channel opposite to the bean-dropping channel. The bean-dropping channel has a first opening, and the downward sliding channel has a second opening. Baffles are installed in both the bean-dropping channel and the downward sliding channel. As the rotating assembly rotates on the bean hopper, the first and second openings, together with the baffles, open and close.

[0004] However, the above solutions are complex in structure, costly, and cumbersome to operate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a simple, low-cost and easy-to-operate bean hopper valve structure for a coffee grinder, based on the current state of the technology.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problem is: a bean hopper valve structure for a coffee grinder, including...

[0007] The machine body has a grinding chamber inside;

[0008] A bean hopper, installed on top of the machine body, has a bean storage chamber inside and a feed inlet at the bottom for connecting the grinding chamber and the bean storage chamber; and

[0009] A valve assembly, installed at the bottom of the bean hopper, is used to open and close the discharge port;

[0010] Its characteristic is that the bean hopper is rotatably mounted on the machine body;

[0011] The valve assembly includes:

[0012] A rotating ring, rotatably mounted at the bottom of the bean hopper and circumferentially confined within the machine body, has multiple circumferentially spaced limiting grooves on the rotating ring; and

[0013] Multiple valve plates are arranged at intervals along the circumference of the rotating ring and correspond to the limiting grooves. Each valve plate is rotatably connected to the bottom of the bean bin and has a limiting post that can be rotatably inserted into the corresponding limiting groove, so that all the valve plates can block or release the material discharge port relative to the bean bin during the rotation of the bean bin.

[0014] To facilitate the installation of the rotating ring and the valve plate, the valve assembly also includes a fixing ring located below the bean hopper. The fixing ring is fixed relative to the bean hopper and there is a sandwich between the two. The rotating ring and the valve plate are both located within the sandwich.

[0015] In order to maximize the adjustment range of the material discharge amount, when the valve assembly is closed, the heads of all the valve plates extend out of the interlayer and jointly block the material discharge port.

[0016] With the valve assembly fully open, all valve plates are concealed within the interlayer.

[0017] In order to achieve a fixed connection between the fixing ring and the bean hopper while facilitating the rotational connection of the valve plate at the bottom of the bean hopper, the fixing ring is connected to the bean hopper through multiple connecting shafts arranged at intervals along its circumference. The valve plate corresponds to the connecting shaft, and each valve plate is rotatably connected to the outer circumference of the corresponding connecting shaft.

[0018] In order to achieve large-angle rotation of the valve plate while ensuring that the relative rotation angle between the fixed ring and the rotating ring is small, the limiting post is located at the tail of the valve plate, and the connecting shaft is located in the middle of the valve plate near the tail.

[0019] To simplify the structure, the connecting shaft is a stud.

[0020] In order to facilitate the removal of the rotating ring from the machine body while achieving circumferential positioning of the rotating ring within the machine body, multiple arc-shaped flanges are provided on the inner wall of the machine body at intervals along their circumference. A limiting channel is provided between the adjacent ends of two adjacent arc-shaped flanges. Multiple second limiting protrusions corresponding to the limiting channels are provided on the outer periphery of the rotating ring. Each of the second limiting protrusions can be inserted into the corresponding limiting channel.

[0021] To facilitate the placement and removal of the bean hopper on the top of the machine body and to prevent the bean hopper from detaching from the machine body during operation, the outer periphery of the fixing ring is provided with a plurality of first limiting protrusions corresponding to the second limiting protrusion.

[0022] When the valve assembly is closed, the first limiting protrusion can enter and exit the machine body through the corresponding limiting channel;

[0023] When the valve assembly is open, the first limiting protrusion is located below the corresponding arc-shaped flange.

[0024] To facilitate reminding users whether the valve assembly is in the closed state, at least one of the second limiting protrusions and the corresponding first limiting protrusions have corresponding protrusions and grooves on their opposite surfaces;

[0025] When the valve assembly is closed, the protrusion is positioned within the groove.

[0026] When the valve assembly is open, the protrusion disengages from the groove.

[0027] In order to grind the coffee beans in the grinding chamber, a grinding device is provided in the grinding chamber.

[0028] Compared with the prior art, the advantages of this utility model are as follows: by rotating the bean hopper on the machine body, and installing the valve assembly consisting of the rotating ring and multiple valve plates at the bottom of the bean hopper, since the rotating ring can be circumferentially confined within the machine body, and each valve plate is rotatably connected to the bottom of the bean hopper, and the limiting post of each valve plate is inserted into the limiting groove of the rotating ring to form a constraint relationship, all valve plates can block or release the material discharge port relative to the rotation of the bean hopper during the rotation process. This solution has a simple structure, low cost and simple operation. Attached Figure Description

However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings.

For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0038] like Figures 1 to 7 The image shows a preferred embodiment of the bean hopper valve structure of the coffee grinder of this invention. The coffee grinder's bean hopper valve structure includes a body 1, a bean hopper 2, a valve assembly 3, and a grinding device 4.

[0039] The machine body 1 has a grinding chamber 10 inside and an open top; two arc-shaped flanges 11 are provided on the inner wall of the top of the machine body 1, which are arranged circumferentially, and a limiting channel 111 is provided between the adjacent ends of the two adjacent arc-shaped flanges 11.

[0040] The bean hopper 2 is rotatably mounted on top of the machine body 1. Specifically, the interior of the bean hopper 2 has a bean storage chamber 20, and the bottom of the bean hopper 2 has a discharge port 21 for connecting the grinding chamber 10 and the bean storage chamber 20.

[0041] The valve assembly 3 is installed at the bottom of the bean hopper 2 and is used to open and close the aforementioned discharge port 21. In this embodiment, the valve assembly 3 includes a fixed ring 31, a rotating ring 32, and a valve plate 33.

[0042] Specifically, the fixing ring 31 is connected to the bottom of the bean hopper 2 by five connecting shafts 311 arranged at intervals along its circumference, and there is a sandwich 310 between the fixing ring 31 and the bean hopper 2; the outer periphery of the fixing ring 31 is provided with two first limiting protrusions 312 corresponding to the aforementioned limiting channel 111; in this embodiment, the aforementioned connecting shaft 311 is a stud.

[0043] The rotating ring 32 is rotatably installed in the aforementioned interlayer 310; the inner periphery of the rotating ring 32 has five limiting grooves 321 arranged circumferentially thereon; the outer periphery of the rotating ring 32 is provided with two second limiting protrusions 322 corresponding to the aforementioned first limiting protrusions 312, and each second limiting protrusion 322 can be inserted into the corresponding limiting channel 111, thereby realizing circumferential limiting within the body 1; in this embodiment, one of the second limiting protrusions 322 and the corresponding first limiting protrusion 312 have corresponding protrusions 3221 and grooves 3121 on their opposite surfaces;

[0044] There are five valve plates 33, which are arranged at intervals along the circumference of the rotating ring 32 and correspond one-to-one with the connecting shaft 311 and the limiting groove 321. Each valve plate 33 is located in the interlayer 310 and is rotatably connected to the outer periphery of the corresponding connecting shaft 311. Each valve plate 33 has a limiting post 331 protruding from the top surface of its tail, which can be rotatably inserted into the corresponding limiting groove 321. In this embodiment, the connecting shaft 311 is located in the middle of the valve plate 33 near the tail, so that a small relative rotation angle between the fixed ring 31 and the rotating ring 32 can achieve a large-angle self-rotation of the valve plate 33.

[0045] The grinding device 4 is located inside the grinding chamber 10.

[0046] By rotating the bean hopper 2, the fixed ring 31 can be rotated relative to the movable ring 32, and then the valve plate 33 can be rotated around the axis of the bean hopper 2 via the connecting shaft 311. Due to the constraint relationship between the limiting post 331 of the valve plate 33 and the limiting groove 321 of the rotating ring 31, each valve plate 33 will rotate around the corresponding connecting shaft 311 during the rotation of the bean hopper 2, thereby blocking or releasing the blocking of the discharge port 21.

[0047] With valve assembly 3 closed, such as Figure 2 , Figure 3 and Figure 5 As shown, the heads of all valve plates 33 extend out of the interlayer 310 and together block the material discharge port 21; the protrusion 3221 of the second limiting protrusion 322 is limited to the groove 3121 of the first limiting protrusion 312; the first limiting protrusion 312 can enter and exit the machine body 1 through the corresponding limiting channel 111, thereby facilitating the loading and unloading of the bean hopper 2 at the top of the machine body 1.

[0048] With valve assembly 3 in the open state, such as Figure 6 and Figure 7As shown, the protrusion 3221 of the second limiting protrusion 322 disengages from the groove 3121 of the first limiting protrusion 312; the first limiting protrusion 312 is located below the corresponding arc-shaped flange 11, thereby preventing the bean hopper 2 from disengaging from the machine body 1 in the working state; in addition, when the valve assembly 3 is fully open, all valve plates 33 are hidden in the interlayer 310 to avoid obstructing the material discharge port 21.

[0049] The working principle of this embodiment is as follows:

[0050] (1) When grinding beans is required:

[0051] First, rotate the rotating ring 32 until the protrusion 3221 of the second limiting protrusion 322 is limited to the groove 3121 of the first limiting protrusion 312. At this time, as... Figure 3 As shown, valve assembly 3 is in the closed state, and the heads of all valve plates 33 extend out of the interlayer 310 and jointly block the discharge port 21;

[0052] Then, the first limiting protrusion 312 of the fixing ring 31 is aligned with the corresponding limiting channel 111 and inserted into the body 1 until the second limiting protrusion 322 of the rotating ring 32 is inserted into the corresponding limiting channel 111. At this time, as Figure 2 and Figure 5 As shown, the bean hopper 2 is installed on top of the machine body 1, and the valve assembly 3 is still in the closed state;

[0053] Next, rotate the bean hopper 2. After the fixing ring 31 rotates synchronously with the bean hopper 2, the first limiting protrusion 312 is positioned below the corresponding arc-shaped flange 11, thus preventing the bean hopper 2 from detaching from the machine body 1 during operation. Simultaneously, the connecting shaft 311 drives the valve plate 33 to revolve around the axis of the bean hopper 2. Due to the constraint relationship between the limiting post 331 of the valve plate 33 and the limiting groove 321 of the rotating ring 31, each valve plate 33 will rotate around its corresponding connecting shaft 311 during the rotation of the bean hopper 2, thus releasing the blockage of the discharge port 21. At this time, if... Figure 6 and Figure 7 As shown, valve assembly 3 is in the open state, and coffee beans in the bean storage chamber 20 can enter the grinding chamber 10 through the feed inlet 21;

[0054] Finally, the grinding device 4 is activated to grind the coffee beans in the grinding chamber 10 into coffee powder;

[0055] (2) After grinding the beans, rotate the bean hopper 2 in the opposite direction until the protrusion 3221 of the second limiting protrusion 322 is limited to the groove 3121 of the first limiting protrusion 312. At this time, the first limiting protrusion 312 can enter and exit the machine body 1 through the corresponding limiting channel 111, and the bean hopper 2 can be removed from the machine body 1.
