DETAILED DESCRIPTION

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described content cannot completely exemplify all implementation schemes. The following embodiments are only a part of many implementation schemes, not all of them. Based on the disclosure of this utility model, all other implementation results obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0021] Example

[0022] like Figure 1 As shown, a dual-compartment bean hopper structure includes a bean hopper 1 with a sloping bottom. A grinding spout 2 is located at the bottom of the slope, and a rotatable and detachable switching knob 3 is mounted on the grinding spout 2. The bean hopper 1 also includes a partition 11 that divides it into two compartments. One end of the partition 11 connects to the switching knob 3 to prevent coffee beans from the two compartments from mixing. The switching knob 3 has a baffle 31 that blocks coffee beans from entering the grinding spout 2. The partition 11 divides the bean hopper into two relatively independent compartments, and coffee beans from both compartments enter the grinding spout 2 through the same switching knob 3. Its structure is simple and does not occupy more space than existing single-compartment bean hoppers. Compared to currently available fixed bean hoppers, the switching knob 3 of this invention is detachable, exposing the grinder located below it for easy cleaning.

[0023] like Figure 2 As shown, the switching knob 3 also includes a positioning mechanism 32, which positions the switching knob 3 to three different positions. The switching knob 3 is limited by the positioning mechanism 32, allowing for accurate positioning and indication of the three positions, as shown... Figure 5 and Figure 6 As shown, rotating the switching knob 3 allows the baffle 31 to block the coffee beans in the two chambers respectively, or to leave both unblocked, thus creating a blend of two types of coffee beans.

[0024] like Figure 3 and Figure 4As shown, the switching knob 3 includes a rotating cap 33 at the top end, the rotating cap 33 is connected to the baffle 31 through the rotating shaft 34, the positioning mechanism 32 includes a clamping ring 321 composed of three wedge-shaped clamping jaws connected to the rotating shaft 34 below the rotating cap 33, a clamping seat 322 is arranged below the clamping ring 321 and is in sliding engagement with the clamping ring 321, and a spring 323 is arranged below the clamping seat 322 and is configured to make the clamping seat 322 resiliently upward. The clamping ring 321 and the clamping seat 322 are designed in the style of a three-lobed triangular long side connected to form a ring, the clamping ring 321 is fixed on the rotating shaft 34 and is opposite the rotating cap 33 and is fixed, and the clamping seat 322 is clamped on the indicating cap 35 and is opposite the bean bin and is fixed. When it is necessary to change the coffee taste, the switching knob 3 is rotated, i.e., the rotating knob 33, the rotating shaft 34 and the clamping ring 321 are rotated, the clamping ring 321 and the clamping seat 322 can be clamped at three fixed point positions, the rotating cap 33 can be accurately positioned in three directions, and thus three gears are distinguished.

[0025] As shown in Figure 3 and Figure 4 , the switching knob 3 includes an indicating cap 35 below the rotating cap 33, and the switching knob 3 further includes a cover 36 connected to the inner wall of the bean bin 1 and the partition 11, and the indicating cap 35 is clamped with the cover 36 so that the two can be synchronously rotated with the rotating shaft 34 as the center. The cover 36 can prevent the caked coffee beans from entering the grinding bean port 2 and blocking the lower beans, and the indicating cap 35 and the cover 36 are fixed and stationary relative to the bean bin.

[0026] As shown in Figure 5 and Figure 6 , the switching knob 3 further comprises a support 37 at the bottom, the support 37 is shaped to fit the grinding bean port 2, and the support 37 is detachably clamped on the grinding bean port 2. The support 37 supports the entire switching knob 3 above the grinding bean port 2, and the support 37 is clamped with the grinding bean port 2 by rotation or other means. When it is necessary to clean the grinder, the entire switching knob 3 can be removed by separating the clamping part, which is convenient and fast.

[0027] As shown in Figure 4 , a dismounting ring 38 is arranged between the indicating cap 35 and the cover 36, the cover 36 is provided with an arc-shaped through hole 39, and the dismounting ring 38 passes through the arc-shaped through hole 39 and is clamped with the support 37 to drive the support 37 to synchronously rotate. When the coffee taste is switched, the indicating cap 35, the dismounting ring 38, the cover 36 and the support 37 are stationary relative to the bean bin, and the rotating knob 33, the rotating shaft 34 and the clamping ring 321 are synchronously rotated. When the switching knob 3 is dismounted, the dismounting ring 38 and the support 37 are synchronously rotated, i.e., the support 37 is driven by the dismounting ring 38 to synchronously rotate, so that the support 37 is separated from the grinding bean port 2, and thus the entire switching knob 3 is dismounted, the grinding bean port 2 is exposed, and the grinder is conveniently cleaned.

[0028] As shown in Figure 6As shown, the support 37 and the side wall of the bean bin 1 enclose the two lower bean ports 21 from the bean port 2. The support 37 has three support columns, one of which is arranged at the partition 11, and the other two are connected with the side wall of the bean bin 1 to enclose the two lower bean ports 21. The rotating knob 3 can make the baffle 31 block one of the two lower bean ports, or abut against the side wall of the bean bin 1 to expose the two lower bean ports at the same time, so as to mix the coffee bean port tastes.

[0029] As Figure 1 The cover 36 is attached to the side wall of the bean bin 1. The cover 36 is shaped to be attached to the side wall and can block the caked coffee beans in all directions. In addition, when the rotating knob 3 is rotated and detached, only the support 37 is rotated and detached, and the cover 36 is still stationary relative to the bean bin 1, so the shape does not affect the disassembly.

[0030] The embodiments of the utility model are described in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiments, and equivalent changes made to the structure, shape and principle within the knowledge range possessed by ordinary skilled persons in the technical field belong to the protection range of the utility model.
