Detailed Implementation

[0033] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0034] Please refer to Figure 1-4 In one embodiment, this utility model provides a coffee grinder without a grinding channel, comprising:

[0035] The outer casing 100 is provided with a feed inlet 110 and a first discharge outlet 120;

[0036] Grinding component 200 is disposed inside housing 100 and is used for grinding materials. Grinding component 200 is provided with a second discharge port 240.

[0037] Baffle 300 is set at the first discharge port 120. Baffle 300 has a material leakage point. After being ground by the grinding component 200, the material can pass through the material leakage point and pass through the baffle 300.

[0038] The first discharge port 120 overlaps with the second discharge port 240.

[0039] The overlap of the first discharge port 120 and the second discharge port 240 means that the first discharge port 120 and the second discharge port 240 overlap in both the horizontal and vertical directions, especially in the vertical direction. The ground material passes through the second discharge port 240 to leave the interior of the grinding assembly 200 and at the same time passes through the first discharge port 120 to leave the interior of the outer shell 100.

[0040] The top of the outer casing 100 is also provided with a detachable cover 150.

[0041] In this embodiment, the first discharge port 120 on the outer shell 100 coincides with the second discharge port 240 on the grinding assembly 200. When the material is ground into powder by the grinding assembly 200 and leaves the grinding assembly 200 through the second discharge port 240, it also leaves the outer shell 100 through the first discharge port 120. This eliminates the traditional powder channel structure and directly forms an open powder discharge path, reducing the residue of powder in the outer shell 100. At the same time, a baffle 300 that can pass through the ground material is also provided, which can not only allow the material to leave the outer shell 100 normally, but also prevent the user from accidentally touching the grinding disc 230 during use.

[0042] In a further embodiment of the present invention, the first discharge port 120 is located at the bottom of the outer shell 100, and the baffle 300 is connected to the bottom of the outer shell 100. The size of the baffle 300 projected on the horizontal plane is larger than the size of the first discharge port 120 projected on the horizontal plane.

[0043] In this embodiment, the first discharge port 120 is located at the bottom of the outer shell 100. After being ground by the grinding component 200, the material leaves the outer shell 100 through the first discharge port 120 under the action of gravity. The size of the baffle 300 projected on the horizontal plane is larger than the size of the first discharge port 120 projected on the horizontal plane, ensuring that the baffle 300 can completely cover the first discharge port 120.

[0044] In a further embodiment of the present invention, the baffle 300 is elastic, and the two opposite ends of the outer periphery of the baffle 300 are respectively provided with a lever position 310 and a connecting component 320. The baffle 300 is connected to the outer shell 100 through the connecting component 320, and the projection of the lever position 310 on the horizontal plane is located outside the outer shell 100.

[0045] In this embodiment, the baffle 300 is elastic and can deform under the action of external force. One end of the baffle 300 is connected to the bottom of the outer shell 100 and fixed thereto. The other end of the baffle 300 is provided with a lever position 310. The user can move the lever position 310 to deform the other end of the baffle 300 away from the bottom of the outer shell 100. When the user releases the lever position 310, the baffle 300 rebounds and collides with the bottom of the outer shell 100, generating vibration and shaking off the material adsorbed on the baffle 300, further reducing the adsorption of material by the grinder.

[0046] In a further embodiment of this utility model, the grinding assembly 200 includes, from top to bottom:

[0047] Grinding motor 210;

[0048] Cutter head support 220;

[0049] The grinding disc 230 is rotatably connected to the grinding motor 210; the output end of the grinding motor 210 passes through the disc bracket 220 and is connected to the grinding disc 230 to provide grinding power to the grinding disc 230; the disc bracket 220 is used to mount the grinding disc 230.

[0050] In a further embodiment of the present invention, the second discharge port 240 of the grinding assembly 200 is disposed at the bottom of the grinding disc 230.

[0051] In this embodiment, the second discharge port 240 is located at the bottom of the grinding disc 230, that is, at the bottom of the grinding assembly 200. When the material is ground into powder by the grinding disc 230, it can be directly discharged into the grinding assembly 200 under the action of gravity, reducing the bends in the material discharge path and avoiding powder accumulation at the bends in the path.

[0052] Please refer to Figure 5 In a further embodiment of this utility model, a gap is left between the grinding motor 210 and the outer shell 100 to form a feeding channel 130, and a tapered channel wall 250 with a wider upper part and a narrower lower part is also provided between the cutter head support 220 and the grinding cutter head 230, and a gap is left between the grinding cutter head 230 and the tapered channel wall 250 to form a grinding cavity 140.

[0053] In a further embodiment of this utility model, a switch assembly 400 is also provided. The switch assembly 400 can move back and forth between an open position and a closed position. When the switch assembly 400 is in the open position, one end of the feed channel 130 is connected to the grinding chamber 140. When the switch assembly 400 is in the closed position, one end of the feed channel 130 is isolated from the grinding chamber 140, and the other end of the feed channel 130 is connected to the feed port 110.

[0054] Please refer to Figure 6 In this embodiment, a switch assembly 400 is provided. The user can adjust the switch assembly 400 to precisely control the amount of material falling into the grinding chamber 140, so as to achieve precise feeding and avoid the grinding disc 230 from getting stuck due to too much material inside the grinding chamber 140.

[0055] In a further embodiment of the present invention, the switch assembly 400 includes a rotating ring 410 and a blocking block 420. The rotating ring 410 is rotatably disposed on the housing 100. The rotating ring 410 is connected to the blocking block 420 and drives the blocking block 420 to rotate. When the switch assembly 400 is closed, the blocking block 420 is located at one end of the feed channel 130 and isolates the feed channel 130 from the grinding chamber 140.

[0056] In this embodiment, the switch assembly 400 includes a rotating ring 410 disposed on the housing 100. The user can directly adjust the rotating ring 410 from outside the device to adjust the blocking block 420 and control the switch assembly 400 to switch on or off.

[0057] In a further embodiment of this utility model, the switch assembly 400 further includes a baffle plate 430, which is disposed between the grinding motor 210 and the cutter head support 220. The baffle plate 430 is provided with a recess 431, which together with the interior of the outer shell 100 forms a through hole that matches the shape of one end of the feed channel 130. The material in the feed channel 130 enters the grinding chamber 140 through the through hole. The shape of the baffle block 420 matches the shape of the through hole. When the switch assembly 400 is in the closed position, the baffle block 420 is located above the through hole and isolates the feed channel 130 from the grinding chamber 140. When the switch assembly 400 is in the open position, the baffle block 420 rotates and moves away from the top of the through hole, so that the feed channel 130 is connected to the grinding chamber 140.

[0058] In this embodiment, the switch assembly 400 is also provided with a baffle plate 430, which is located between the grinding motor 210 and the blade holder 220. It can effectively prevent the material powder raised by the grinding blade 230 during operation from drifting to the grinding motor 210 and affecting the operation of the grinding motor 210.

[0059] In a further embodiment of this utility model, the baffle 300 is made of spring steel wire, with gaps between the spring steel wires forming a material leakage point.

[0060] In this embodiment, the baffle 300 is made of spring steel wire. The diameter of the spring steel wire is relatively small, only 1 mm, and the cross-sectional area is very small. During the falling process, very little coffee powder will adhere to the baffle 300.

[0061] In a further embodiment of this utility model, the baffle 300 is in the shape of a spiral disc.

[0062] In this embodiment, the relative distance between the two turns of the spiral is 3mm. This design ensures that the gold finger, which simulates a human hand test, cannot pass through, and ensures that the consumer's finger will not touch the grinding disc 230 when using it.

[0063] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
