However, the hand crank of this grinder protrudes outwards, taking up a large area and making storage inconvenient after use. Utility Model Content

[0003] One objective of this application is to provide a folding grinder with a convenient handle for easy storage.

[0004] The technical solution adopted in this application is: a folding grinder with a handle, including a grinder body, a hand crank and a grip, a top cover on the top of the grinder body, one end of the hand crank is rotatably connected to the grip, and the other end of the hand crank is rotatably connected to the top cover. In the folded state, the grip is located below the grinder body.

[0005] Compared with the prior art, the advantages of this application are that the hand crank can rotate relative to the top cover, making it easy for the hand crank to rotate closer to the grinder body for folding and storage, reducing the space occupied; the handle can rotate relative to the hand crank, making it easy for the user to rotate the top cover. When the top cover rotates, the direction of the hand crank changes, while the direction of the handle remains unchanged, meaning that the handle will not rotate relative to the user's hand, ensuring a comfortable grip; after the hand crank is rotated and folded, the handle can be stored under the grinder body, taking up little space overall and making it easier to store.

[0006] In some embodiments of this application, the hand crank and the handle form an L-shape, with a simple overall structure. The handle is easy to fold and store at the bottom. The hand crank is close to the grinder body, occupying little space. In the unfolded state, the handle is vertically upward, making it convenient for the user to hold the handle and perform rotation operations.

[0007] In some embodiments of this application, the top cover is provided with a fixing groove, and the hand crank is located on the fixing groove in the unfolded state. The fixing groove can accommodate part of the hand crank when it is unfolded, and the groove wall can provide support for the hand crank, reducing the risk of damage to the rotation point of the hand crank and the top cover, and extending the service life of the hand crank.

[0008] Furthermore, the top cover is provided with at least one outwardly extending mounting plate, and the hand crank is rotatably connected to the mounting plate. The design of the mounting plate reduces the difficulty of installing the hand crank and facilitates the installation between the hand crank and the top cover. The mounting plate can also strengthen the structural strength of the top cover and prevent deformation when the top cover is stuck during rotation.

[0009] Furthermore, the mounting plates are provided in two spaced-apart configurations, with the space between the two mounting plates communicating with the fixing groove. The hand crank is located between the two mounting plates. The spaced-apart arrangement of the two mounting plates facilitates the installation of the hand crank between them, and the communication between the two mounting plates and the fixing groove allows the hand crank to directly enter the fixing groove when it is unfolded and rotated. At the same time, the hand crank can contact the mounting plate in both forward and reverse rotations, ensuring reliable forward and reverse rotation of the hand crank.

[0010] In some embodiments of this application, in the folded state, at least a portion of the hand crank handle and the grinder body form a clearance groove. The clearance groove design facilitates the user's gripping of the hand crank handle and allows the hand crank handle to unfold relative to the grinder body.

[0011] In some embodiments of this application, in the folded state, the handle is located directly below the grinder body; the bottom surface of the grinder body mates with one end of the handle. With the handle directly below the grinder body, the overlap area is maximized, resulting in a smaller footprint. The shape of one end of the handle matches the bottom surface of the grinder body; that is, after the hand crank is folded, the shape of the handle at the bottom is the same as the shape of the bottom of the grinder body, resulting in a more aesthetically pleasing overall appearance. Simultaneously, the center of gravity remains essentially unchanged, ensuring good overall stability.

[0012] Furthermore, in the folded state, the end face of the handle fits against the bottom surface of the grinder body, preventing the handle from wobbling relative to the grinder body and ensuring stability when placed.

[0013] In some embodiments of this application, the grinder body includes a housing, a grinding assembly located inside the housing, and a powder hopper located at the bottom of the housing. The powder hopper is connected to the housing, and the top cover is detachably connected to the housing.

[0014] Furthermore, the grinding assembly includes an inner grinding head and an outer grinding head, with the outer grinding head fixedly connected to the housing and the inner grinding head connected to the top cover. Attached Figure Description

[0019] To enable those skilled in the art to better understand the technical solutions of this disclosure, the following detailed, clear, and complete description of this disclosure is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this disclosure and are not intended to limit it.

[0020] In the description of this application, the use of "first" and "second" is for the purpose of distinguishing technical features only, and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated or the order of the technical features indicated.

[0021] Those skilled in the art should understand that in the disclosure of this application, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this application.

[0022] Example 1:

[0023] This embodiment provides a folding handle grinder, such as Figure 1 , Figure 2 , Figure 3 As shown, the device includes a grinder body 1, a hand crank 2, and a handle 3. The top of the grinder body 1 is provided with a top cover 4. One end of the hand crank 2 is rotatably connected to the handle 3, and the other end of the hand crank 2 is rotatably connected to the top cover 4. In the folded state, the handle 3 is located below the grinder body 1.

[0024] The hand crank 2 can rotate relative to the top cover 4, making it easy for the hand crank 2 to rotate closer to the grinder body 1 for folding and storage, reducing the space occupied. The handle 3 can rotate relative to the hand crank 2, making it easy for the user to rotate the top cover 4. When the top cover 4 rotates, the direction of the hand crank 2 changes, while the direction of the handle 3 remains unchanged. That is, the handle 3 will not rotate relative to the user's hand, ensuring a comfortable grip. After the hand crank 2 is rotated and folded, the handle 3 can be stored under the grinder body 1, taking up little space and making it easier to store.

[0025] For structural reliability, the hand crank 2 and the handle 3 form an L-shape, which is simple in overall structure. The L-shape makes it easy to fold the handle 3 and store it at the bottom. The hand crank 2 is close to the grinder body 1, which occupies little space. When unfolded, it is easy for the user to hold. In the unfolded state, the handle 3 is vertically upward, which makes it easy for the user to hold the handle 3 to perform the rotation operation.

[0026] To ensure reliable rotation of the hand crank 2, the top cover 4 is provided with a fixing groove 5. In the unfolded state, the hand crank 2 is located in the fixing groove 5. The fixing groove 5 can accommodate part of the hand crank 2 when it is unfolded, so that when the user rotates the hand crank 2, the hand crank 2 is in contact with the groove wall of the fixing groove 5. The groove wall of the fixing groove 5 can provide support for the hand crank 2, and part of the force on the hand crank 2 can be directly transmitted to the top cover 4 to drive the top cover 4 to rotate synchronously, instead of the top cover 4 being rotated entirely through the rotation point between the hand crank 2 and the top cover 4. This reduces the risk of damage to the rotation point between the hand crank 2 and the top cover 4 and extends the service life of the hand crank 2.

[0027] To ensure a reliable connection between the hand crank 2 and the top cover 4, the top cover 4 is provided with at least one outwardly extending mounting plate 6, and the hand crank 2 is rotatably connected to the mounting plate 6. The design of the mounting plate 6 reduces the difficulty of installing the hand crank 2 and facilitates the installation between the hand crank 2 and the top cover 4. The mounting plate 6 also strengthens the structural strength of the top cover 4, preventing deformation when the top cover 4 becomes stuck during rotation. In this embodiment, the hand crank 2 is rotatably connected to the mounting plate 6 via a rotating shaft 13.

[0028] To ensure a reliable connection between the hand crank 2 and the top cover 4, two mounting plates 6 are provided and arranged at an interval. The two mounting plates 6 communicate with the fixing groove 5, and the hand crank 2 is located between the two mounting plates 6. The interval arrangement of the two mounting plates 6 facilitates the installation of the hand crank 2 between them, and the communication between the two mounting plates 6 and the fixing groove 5 allows the hand crank 2 to directly enter the fixing groove 5 when it is unfolded and rotated. At the same time, the hand crank 2 can contact the mounting plate 6 in both forward and reverse rotation, ensuring reliable forward and reverse rotation of the hand crank 2.

[0029] In this embodiment, the mounting plate 6 and the fixing groove 5 are on the same straight line. The fixing groove 5 extends from one side of the top cover 4 to the other side of the top cover 4. The inner side of the mounting plate 6 and the groove wall of the fixing groove 5 are on the same plane. The side of the hand crank 2 has the largest contact area with the groove wall of the fixing groove 5, ensuring that the hand crank 2 rotates reliably. The mounting plate 6 is located on one side of the top cover 4 in the radial direction. The fixing groove 5 passes through the center of the top cover 4, which is the largest straight distance of the hand crank 2, so that the torque between the handle 3 and the top cover 4 is the longest, and the user rotates the top cover 4 with the least effort.

[0030] For the grinder body 1 to be reliable, the grinder body 1 includes a housing 8, a grinding component 9 located inside the housing 8, and a powder hopper 12 located at the bottom of the housing 8. The powder hopper 12 is connected to the housing 8, and the top cover 4 is detachably connected to the housing 8. The top cover 4 is detachable, which facilitates the placement of the material to be ground into the housing 8; the powder hopper 12 is used to hold the ground powder.

[0031] To ensure the reliability of the grinding assembly 9, the grinding assembly 9 includes an inner grinding head 10 and an outer grinding head 11. The outer grinding head 11 is fixedly connected to the housing 8, and the inner grinding head 10 is connected to the top cover 4. In use, the user rotates the handle 3, which drives the hand crank 2 to rotate. The hand crank 2 drives the top cover 4 to rotate, and the top cover 4 drives the inner grinding head 10 to rotate, causing the inner grinding head 10 and the outer grinding head 11 to rotate relative to each other for grinding.

[0032] To facilitate the unfolding of the hand crank 2, in the folded state, at least a portion of the hand crank 2 is formed between the hand crank 2 and the housing 8 or at least a portion of the hand crank 2 and the powder container 12. The design of the clearance groove 7 makes it easy for the user to grasp the hand crank 2 and facilitates the unfolding of the hand crank 2 relative to the grinder body 1.

[0033] In this embodiment, at least a portion of the hand crank 2 and the housing 8 form an avoidance groove 7; the hand crank 2 is stepped, and in the folded state, the hand crank 2 gradually moves outward from bottom to top and forms an avoidance groove 7 with the grinder body 1; of course, a groove may also be provided on the hand crank 2 or the grinder body 1.

[0034] To reduce the footprint, in the folded state, the handle 3 is positioned directly below the powder compartment 12; the bottom surface of the powder compartment 12 mates with one end of the handle 3. With the handle 3 directly below the powder compartment 12, the overlap area is maximized, resulting in a smaller footprint. The mating of one end of the handle 3 with the bottom surface of the powder compartment 12 means that when the hand crank 2 is folded, the bottom surface of the powder compartment 12 and the top surface of the handle 3 mate, facilitating the placement of the handle 3 below the powder compartment 12. Furthermore, the horizontal cross-sectional shape of the handle 3 is identical to the bottom horizontal cross-sectional shape of the powder compartment 12. After the hand crank 2 is folded, the shape of the handle 3 at the bottom matches the shape of the powder compartment 12, resulting in a more aesthetically pleasing overall appearance while maintaining a relatively stable center of gravity. Of course, the shapes of the powder compartment 12 and the handle 3 can also differ; for example, the powder compartment 12 can be cylindrical, while the handle 3 can be heart-shaped, five-pointed star-shaped, etc.

[0035] In this embodiment, the powder container 12 is cylindrical, and the handle 3 is disc-shaped.

[0036] To ensure the grinder is placed stably, in the folded state, the end face of the handle 3 is in contact with the bottom surface of the powder container 12, which prevents the handle 3 from shaking relative to the grinder body 1 and ensures the stability of the placement.

[0037] 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. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
