The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0032] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0033] like Figures 1 to 6 As shown, an embodiment of a bean hopper structure 100 with an opening and closing function is used to be installed on a coffee grinder 10. The bean hopper structure 100 includes a bean hopper body 110 and a cover plate 120. The bean hopper body 110 has a feeding trough 111 and a feeding port 112 connected to the feeding trough 111. The feeding port 112 is formed on the outer wall of the bean hopper body 110. The feeding trough 111 is used to communicate with the grinding chamber of the coffee grinder 10. The cover plate 120 includes a closed portion 121 and a pivot portion 122 connected to each other. The closed portion 121 is disposed opposite to the feeding port 112 and is used to open and close the feeding port 112. The pivot portion 122 is rotatably connected to the bean hopper body 110. When the feeding port 112 is in the open state, the closed portion 121 is limited to a position away from the feeding port 112, so that when it is necessary to open the feeding port 112, it is only necessary to close the closed portion 121 relative to the bean hopper. When the main body 110 rotates away from the feed inlet 112, the lid 121 is positioned away from the feed inlet 112, thus keeping the feed inlet 112 in an open state. When the feed inlet 112 is closed, the lid 121 is positioned at the feed inlet 112, so that the lid 121 covers the feed inlet 112. Therefore, when it is necessary to close the feed inlet 112, it is only necessary to rotate the lid 121 relative to the bean hopper main body 110 to the feed inlet 112, so that the lid 121 can be positioned at the feed inlet 112, thereby closing the feed inlet 112. Compared with the flip-top grinders in the above-mentioned related technologies, the bean hopper structure 100 with opening and closing function disclosed in this invention greatly reduces the difficulty of opening and closing the feed inlet 112, thereby greatly improving the ease of use of the coffee grinder 10.

[0034] In this embodiment, when it is necessary to close the feed inlet 112, simply rotate the cover 121 away from the feed inlet 112 relative to the bean hopper body 110. The cover 121 will then be positioned away from the feed inlet 112, thus keeping the feed inlet 112 in an open state. This will prevent external dust from entering the grinding chamber of the coffee grinder 10 through the feed inlet 112, greatly improving the quality and taste of the coffee. When it is necessary to open the feed inlet 112, simply rotate the cover 121 relative to the bean hopper body 110 to the feed inlet 112. The cover 121 will then be positioned at the feed inlet 112, thus closing the feed inlet 112.

[0035] The aforementioned bean hopper structure 100 with opening and closing function has a cover 121 positioned opposite to the feed inlet 112. The cover 121 is used to open and close the feed inlet 112, and the pivot 122 is rotatably connected to the bean hopper body 110. When the feed inlet 112 is open, the cover 121 is positioned away from the feed inlet 112, so that when the feed inlet 112 needs to be opened, the cover 121 only needs to be rotated relative to the bean hopper body 110 away from the feed inlet 112, and the cover 121 can be positioned away from the feed inlet 112, thus keeping the feed inlet 112 in the open state. When the feed inlet 112 is closed, the cover 121... The cover 121 is positioned at the feed inlet 112 so that it covers the feed inlet 112. When the feed inlet 112 needs to be closed, the cover 121 only needs to be rotated relative to the bean hopper body 110 to the feed inlet 112, and the cover 121 can be positioned at the feed inlet 112, thereby covering the feed inlet 112 and keeping the feed inlet 112 closed. Compared with the flip-top grinders in the above-mentioned related technologies, the bean hopper structure 100 with opening and closing function disclosed in this invention greatly reduces the difficulty of opening and closing the feed inlet 112, thereby greatly improving the ease of use of the coffee grinder 10.

[0036] like Figures 1 to 3As shown, in one embodiment, the cover plate 120 further includes a limiting part 123. The closing part 121, the pivot part 122, and the limiting part 123 are connected in sequence. The closing part 121 is used to be located at a first preset position on the bean hopper body 110 under the action of a first limiting force. The first preset position is away from the feed inlet 112. When the closing part 121 is located at the first preset position, the closing part 121 is away from the feed inlet 112, so that the feed inlet 112 is in an open state. The limiting part is used to be located at a second preset position on the bean hopper body 110 under the action of a second limiting force. When the limiting part 123 is located at the second preset position, the closing part 121 is located at the feed inlet 112 and closes to the feed inlet 112, so that the feed inlet 112 is in a closed state. When it is necessary to open the feed inlet 112, the closing part 123 is closed. When closed, the limiting part 123 only needs to be rotated relative to the bean hopper body 110 to the second preset position. The limiting part 123 can be limited to the second preset position by the second limiting force. When the limiting part 123 is rotated relative to the bean hopper body 110 to the second preset position, the limiting part 123 can drive the cover part 121 to rotate relative to the bean hopper body 110 to the feed inlet 112 through the lever action, so that the cover part 121 can be limited to the feed inlet 112, and thus the cover part 121 can close the feed inlet 112. Compared with the flip-top grinder in the above-mentioned related technology, the bean hopper structure 100 with opening and closing function disclosed in this invention greatly reduces the difficulty of opening and closing the feed inlet 112, and thus greatly improves the ease of use of the coffee grinder 10.

[0037] like Figures 1 to 3 As shown, in one embodiment, the first limiting force is the resultant force between the magnetic attraction force and the weight of the cover part itself, and the second limiting force is the weight of the limiting part itself, so that when the first limiting force is greater than the second limiting force, the cover part 121 can be reliably limited to the first preset position, so that the cover part 121 can move away from the feed inlet 112, thereby making the feed inlet 112 open; and when the second limiting force is greater than the first limiting force, the limiting part 123 can be reliably limited to the second preset position, so that the limiting part 123 can drive the cover part 121 to rotate relative to the bean hopper body 110 to the feed inlet 112 and cover the feed inlet 112 through the lever action, so that the cover part 121 can be limited to the feed inlet 112 to close the feed inlet 112.

[0038] like Figures 1 to 3As shown, in one embodiment, the bean hopper structure 100 further includes a magnetic closure element (not shown) and a magnetic closure element (not shown). The magnetic closure element is fixed at a first preset position on the bean hopper body 110, and a second preset position is located at the top of the bean hopper body 110. The magnetic closure element is fixed to the limiting part 123. The magnetic closure element and the magnetic closure element are arranged opposite to each other so that when the bean hopper 121 is located at the first preset position, the bean hopper 121 is magnetically limited to the first preset position. The mass of the bean hopper 121 is less than [a certain value]. The mass of the limiting part 123; when the limiting part 123 is located at the second preset position, the limiting part 123 is limited to the first preset position by the weight of the cover part itself, so that when it is necessary to open the feed port 112, it is only necessary to rotate the cover part 121 relative to the bean hopper body 110 to the first preset position, thereby reducing the distance between the magnetic suction member and the suction member of the cover part, so that the resultant force between the magnetic suction member and the suction member of the cover part and the weight of the cover part itself is greater than the weight of the limiting part itself, so that the weight of the cover part 121 is greater than the weight of the limiting part itself. 1. The magnetic attraction between the magnetic suction component and the magnetic adsorption component of the cover part allows it to be magnetically positioned at a first preset position, thereby moving the cover part 121 away from the feed inlet 112 and opening the feed inlet 112. When it is necessary to close the feed inlet 112, the limiting part 123 only needs to be rotated relative to the bean hopper body 110 to a second preset position. The limiting part 123 can then drive the cover part 121 relative to the bean hopper body 110 to rotate to the feed inlet 112 and close it, thereby increasing the magnetic attraction of the cover part. The distance between the magnetic suction member of the cover and the magnetic suction member of the cover is such that the resultant force between the magnetic suction member of the cover and the magnetic suction member of the cover and the weight of the cover itself is less than the weight of the limiting part itself. This allows the limiting part 123 to be limited to the second preset position by the weight of the limiting part itself, and allows the cover 121 to be limited to the feed inlet 112 to close the feed inlet 112. Compared with the flip-top grinder in the above-mentioned related technologies, the bean hopper structure 100 with opening and closing function disclosed in this invention greatly reduces the difficulty of opening and closing the feed inlet 112.

[0039] like Figures 1 to 3 As shown, in one embodiment, both the magnetic clasp and the magnetic adsorption component of the cover are magnets, so that the cover 121 can be more securely positioned at the first preset position.

[0040] It is understood that in other embodiments, the magnetic clasp and the magnetic adsorption component of the lid are not limited to being magnets. For example, in one embodiment, when the magnetic clasp is a magnet, the magnetic adsorption component is an iron sheet; when the magnetic clasp is an iron sheet, the magnetic adsorption component is a magnet, to ensure that the lid 121 can be reliably positioned at the first preset position and to reduce the production cost of the bean hopper structure 100.

[0041] like Figures 1 to 3As shown, in one embodiment, the first limiting force is the weight of the cover portion itself, and the second limiting force is the resultant force between the magnetic attraction force and the weight of the limiting portion itself, so that when the first limiting force is greater than the second limiting force, the cover portion 121 can be reliably limited to the first preset position, so that the cover portion 121 can move away from the feed inlet 112, thereby making the feed inlet 112 open; and when the second limiting force is greater than the first limiting force, the limiting portion 123 can be reliably limited to the second preset position, so that the limiting portion 123 can drive the cover portion 121 to rotate relative to the bean hopper body 110 to the feed inlet 112 and cover the feed inlet 112 through the lever action, so that the cover portion 121 can be limited to the feed inlet 112 to close the feed inlet 112.

[0042] like Figures 1 to 3 As shown, in one embodiment, the bean hopper structure 100 further includes a limiting magnetic suction member (shown in the figure) and a limiting suction member (shown in the figure). The limiting magnetic suction member is fixed at a second preset position on the bean hopper body 110, the second preset position being located at the top of the bean hopper body 110. The limiting suction member is fixed to the limiting part 123, and the limiting magnetic suction member and the limiting suction member are arranged opposite to each other so that when the limiting part 123 is located at the second preset position, the limiting part 123 is magnetically limited to the second preset position; the mass of the cover part 121 The mass of the limiting part 123 is greater than that of the limiting part 123. When the covered part 121 is located at the first preset position, the limiting part 123 is limited to the first preset position by the weight of the covered part itself. This allows the covered part 121 to be rotated relative to the bean hopper body 110 to the first preset position when the feed inlet 112 needs to be opened. This increases the distance between the magnetic suction member and the adsorption member of the limiting part, making the resultant force between the magnetic suction member and the adsorption member and the weight of the limiting part less than the weight of the covered part itself. This ensures that the covered part... The cover 121 can be positioned at a first preset position by its own weight, thereby moving the cover 121 away from the feed inlet 112 and opening the feed inlet 112. When it is necessary to close the feed inlet 112, the limiting part 123 only needs to be rotated relative to the bean hopper body 110 to a second preset position. The limiting part 123 can then drive the cover 121 to rotate relative to the bean hopper body 110 to the feed inlet 112 and close it, thereby reducing the distance between the magnetic suction member and the adsorption member of the limiting part. This ensures that the resultant force between the magnetic attraction between the magnetic attraction member and the adsorption member of the limiting part and the weight of the limiting part itself is greater than the weight of the cover part itself. This allows the limiting part 123 to be limited to the second preset position by the magnetic attraction between the magnetic attraction member and the adsorption member of the limiting part, and allows the cover part 121 to be limited to the feed inlet 112 to close the feed inlet 112. Compared with the flip-top grinder in the above-mentioned related technologies, the bean hopper structure 100 with opening and closing function disclosed in this invention greatly reduces the difficulty of opening and closing the feed inlet 112.

[0043] In one embodiment, both the limiting magnetic member and the limiting adsorption member are magnets, so that the limiting part 121 can be more securely limited to the second preset position.

[0044] It is understood that in other embodiments, the limiting magnetic element and the limiting adsorption element are not limited to being both magnets. For example, in one embodiment, when the limiting magnetic element is a magnet, the limiting adsorption element is an iron sheet; when the limiting magnetic element is an iron sheet, the limiting adsorption element is a magnet, to ensure that the limiting part 121 can be reliably limited to the second preset position and to reduce the production cost of the bean hopper structure 100.

[0045] like Figures 1 to 3 As shown, in one embodiment, the cover portion 121, the pivot portion 122, and the limiting portion 123 are integrally formed to improve the structural compactness of the cover plate 120.

[0046] like Figures 2 to 5 As shown, in one embodiment, a mounting groove 113 is formed at the second preset position. The limiting magnetic member is fixed in the mounting groove 113, and the limiting adsorption member is fixed in the limiting part 123. When the limiting part 123 is located at the second preset position, the limiting part 123 is magnetically limited to the top of the bean hopper body 110. When the limiting part 123 is rotated relative to the bean hopper body 110 to the second preset position, the limiting part 123 can be limited to the second preset position by the magnetic attraction between the limiting magnetic member and the limiting adsorption member. This allows the limiting part 123 to drive the cover part 121 to rotate relative to the bean hopper body 110 to the feed inlet 112 and cover the feed inlet 112 through a lever action, so that the cover part 121 can be limited to the feed inlet 112 to close the feed inlet 112.

[0047] like Figures 3 to 5 As shown, in one embodiment, the pivot portion 122 is provided with a rotating flange 1221, and the bean hopper body 110 is provided with a limiting hole 114 opposite to the rotating flange 1221. The rotating flange 1221 passes through the limiting hole 114 and is rotatably connected to the bean hopper body 110 so that the cover portion 121 and the limiting portion 123 can rotate relative to the bean hopper body 110.

[0048] like Figures 1 to 3As shown, in one embodiment, the feeding trough 111 includes a clearance groove 1111 and a conveying trough 1112 connected to the clearance groove 1111. The clearance groove 1111 is located adjacent to the feed inlet 112 and is connected to the feed inlet 112. The conveying trough 1112 is used to communicate with the grinding chamber. The cover part 121 is disposed opposite to the clearance groove 1111 so that the clearance groove 1111 can provide sufficient clearance space for the cover part 121, so that the cover part 121 can rotate relative to the bean hopper body 110, thereby enabling the cover part 121 to open or close the feed inlet 112.

[0049] like Figures 3 to 5 As shown, in one embodiment, the groove wall of the clearance groove 1111 is formed with an abutment limiting surface 1111a. A first preset position is set at the abutment limiting surface 1111a. There is a preset angle C between the extending direction of the abutment limiting surface 1111a and the length direction of the cross-section of the feed inlet 112, so that when the cover part 121 rotates relative to the bean hopper body 110 to the preset position, the abutment limiting surface 1111a can limit the cover part 121, so that the cover part 121 can be positioned at the preset position by its own weight. At the same time, the cover part 121 drives the limiting part 123 to rotate relative to the bean hopper body 110 through the lever action, so that the limiting part 123 can be tilted relative to the bean hopper body 110 to the preset angle and positioned, so that when the user pours coffee beans into the feed inlet 112, the limiting part 123 can effectively block the coffee beans to prevent coffee beans from splashing, thereby greatly improving the ease of use of the coffee grinder 10.

[0050] It is understandable that when the preset angle is too large, the lid 121 will cause the limiting part 123 to close at the feed inlet 112 due to the excessive rotation angle. When the preset angle is too small, not only will the feed inlet 112 be too small due to the small rotation angle of the lid 121, making it easy for coffee beans to get stuck when pouring them in, but the small rotation angle of the limiting part 123 will also cause the gap between the limiting magnetic suction part and the limiting suction part to be too small, so that there is still a strong magnetic attraction between the limiting magnetic suction part and the limiting suction part. As a result, the lid 121 cannot be positioned at the preset position by its own weight. Therefore, when the pressure applied to the lid 121 is stopped, the lid 121 will close the feed inlet 112 again, which greatly reduces the stability of the coffee grinder 10.

[0051] like Figures 3 to 5As shown, in one embodiment, the preset included angle C is in the range of 50°-80°, so as to avoid the phenomenon that the limiting part 123 covers the feed inlet 112 due to the excessive rotation angle of the cover part 121. At the same time, it can also avoid the phenomenon that the feed inlet 112 is too small or even re-closed due to the excessive rotation angle of the cover part 121, which greatly improves the stability of the coffee grinder 10.

[0052] like Figures 3 to 5 As shown, in one embodiment, a limiting flange 1111b is formed on the side wall of the feed inlet 112 in the clearance groove 1111. The limiting flange 1111b is located at the end of the feed inlet 112 away from the limiting part 123. The limiting flange 1111b is disposed opposite to the cover part 121, and the cover part 121 is disposed in the clearance groove 1111, so that the cover part 121 is limited in the clearance groove 1111. When the cover part 121 covers the feed inlet 112, the top end of the cover part 121 abuts against the bottom end of the limiting flange 1111b, thereby the cover part 121 can be limited in the clearance groove 1111.

[0053] like Figures 1 to 5 Figures 1 to 5 As shown, in one embodiment, an abutment groove 115 is formed at the top of the bean hopper body 110. A limiting groove and a limiting part 123 are disposed opposite to each other. The depth of the abutment groove 115 is the same as the thickness of the limiting flange 1111b, so that when the cover part 121 abuts against the limiting flange 1111b, the limiting part 123 is parallel and abuts against the bottom of the limiting groove. This reduces the distance between the limiting magnetic member and the limiting adsorption member, increases the magnetic attraction between the limiting magnetic member and the limiting adsorption member, and enables the limiting part 123 to be more securely magnetically limited at the top of the bean hopper body 110, thereby improving the stability of the coffee grinder 10 and reducing the material cost and weight of the bean hopper body 110.

[0054] This disclosure also provides a coffee grinder 10, including the bean hopper structure 100 with opening and closing function as described in any of the above embodiments.

[0055] Compared with the prior art, this disclosure has at least the following advantages:

[0056] The coffee grinder 10 described above has a lid 121 positioned opposite the feed inlet 112. The lid 121 is used to open and close the feed inlet 112, and the pivot 122 is rotatably connected to the bean hopper body 110. When the feed inlet 112 is open, the lid 121 is positioned away from the feed inlet 112, so that when the feed inlet 112 needs to be opened, the lid 121 only needs to be rotated relative to the bean hopper body 110 away from the feed inlet 112, and the lid 121 can be positioned away from the feed inlet 112, thus keeping the feed inlet 112 in the open state. When the feed inlet 112 is closed, the lid 121 is positioned... At the feed inlet 112, the cover 121 is positioned to close the feed inlet 112. When it is necessary to close the feed inlet 112, the cover 121 is simply rotated relative to the bean hopper body 110 to the feed inlet 112, and the cover 121 is positioned at the feed inlet 112, thereby closing the feed inlet 112. Compared with the flip-top grinders in the aforementioned related technologies, the bean hopper structure 100 with opening and closing function disclosed in this invention greatly reduces the difficulty of opening and closing the feed inlet 112, thereby greatly improving the ease of use of the coffee grinder 10.

[0057] The embodiments described above are merely illustrative of several implementations of this disclosure, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this disclosure, and these all fall within the protection scope of this disclosure. Therefore, the protection scope of this patent should be determined by the appended claims.
