Description

Technical Field

[0001] This utility model relates to a grinder, and more particularly to a grinding cylinder. Background Technology

[0002] People often use grinders in daily life to process ingredients such as coffee beans, pepper, and cinnamon to ensure that the ingredients bring out their best flavor when eaten or cooked. Currently, most grinders rely on the interaction between the grinding head and the grinding sleeve to grind the ingredients. However, the interaction between the grinding head and the grinding sleeve in existing grinders requires a drive shaft connected to an external power mechanism, making it difficult to completely disassemble the grinding head, grinding sleeve, and other components. This results in incomplete cleaning, which can lead to the accumulation of residual powder over time, producing odors and causing hygiene problems. Furthermore, after prolonged use, the grinding head and grinding sleeve may wear down, making replacement inconvenient. Utility Model Content

[0003] The purpose of this invention is to solve the technical problems of existing grinders being unable to achieve complete cleaning and having difficulty replacing the grinding head and grinding sleeve. To solve the above problems, this invention provides a grinding cylinder in which both the grinding head and grinding sleeve are detachable, allowing the user to clean the grinding cylinder or replace worn grinding heads or grinding sleeves.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] A grinding cylinder, characterized in that it comprises a shell, a grinding head assembly, a grinding sleeve assembly, a connecting seat, a base, and a fixing assembly; the shell and the connecting seat are detachably connected, and the shell and the connecting seat together form a food receiving space; the connecting seat has a grinding through hole, and the grinding sleeve assembly is detachably installed on the grinding through hole; the connecting seat is rotatably connected to the base; the base has a fixing post, and the grinding head assembly is sleeved on the fixing post; the grinding head assembly and the grinding sleeve assembly together form a food grinding space, and the food grinding space communicates with the food receiving space; the fixing assembly is disposed below the grinding head assembly and is detachably connected to the base.

[0006] When the grinding cylinder is in operation, the food to be ground is placed in the food receiving space and falls into the food grinding space, which is connected to the food receiving space. At this time, the housing is rotated manually or by an external power mechanism. The housing drives the grinding sleeve assembly mounted on the connecting seat to rotate through the connecting seat. At this time, the base and the grinding head assembly mounted on the base remain stationary. The relative rotation between the grinding head assembly and the grinding sleeve assembly allows the food to be ground in the food grinding space to be ground. When it is necessary to clean or replace the grinding head or grinding sleeve, the grinding head assembly can be separated simply by disassembling the fixing assembly. The grinding sleeve assembly is also detachably connected to the connecting seat. After separating the grinding head assembly from the grinding head, the grinding sleeve assembly can be further removed, achieving complete disassembly of the grinding head assembly and the grinding sleeve assembly.

[0007] Furthermore, the housing is threadedly connected to the connecting seat. This threaded connection facilitates the disassembly and installation of the housing and the connecting seat.

[0008] Furthermore, the grinding head assembly includes a grinding head, a grinding head adjusting ring, and a grinding head mounting base. The grinding head mounting base is provided with a grinding head mounting post, the grinding head is sleeved on the grinding head mounting post, and the grinding head adjusting ring is installed on the outside of the grinding head mounting base.

[0009] Furthermore, a limiting seat is provided at the bottom of the grinding head mounting post, which restricts the rotation of the grinding head relative to the grinding head mounting post. By mounting the grinding head on the grinding head mounting post, it can be ensured that the grinding head remains stable when the grinding cylinder is working, thereby ensuring that the distance between the grinding head and the grinding sleeve remains unchanged, so as to achieve uniform grinding particle size.

[0010] Furthermore, the inner wall of the grinding head adjusting ring is provided with a snap-fit ​​protrusion, and the outer wall of the grinding head mounting base is provided with an adjusting groove. The snap-fit ​​protrusion is embedded in the adjusting groove to realize the connection between the grinding head adjusting ring and the grinding head mounting base.

[0011] Furthermore, the fixing component includes a fixing plate and a fixing needle. The fixing plate has a fixing hole. When the fixing component is connected to the base, the fixing needle passes through the fixing hole and is engaged with the fixing post. Further, the fixing needle includes an operating part, a through-hole part, and a needle engaging part. The operating part is located at one end of the through-hole part, and the needle engaging part is located at the other end of the through-hole part. The fixing post has a through-hole part and a fixing post locking interface. The fixing post locking interface is located at one end of the through-hole part. When the fixing component is installed on the base, the through-hole part passes through the fixing hole, the through-hole part accommodates the through-hole part, and the needle engaging part is engaged in the fixing post locking interface. Through the cooperation between the fixing needle and the fixing post, the fixing component and the base are detachably connected, and the connection between them is easily released. When the user needs to disassemble, they only need to rotate the operating part of the fixing needle to disengage the needle engaging part from the fixing post locking interface, thus achieving disassembly.

[0012] Furthermore, the bottom of the fixing plate is provided with a positioning bone. When the operating part is aligned with the positioning bone, the needle locking part is engaged in the fixing post locking interface. When the operating part is perpendicular to the positioning bone, the needle locking part disengages from the fixing post locking interface. The positioning bone facilitates the operator's ability to determine whether the fixing needle is properly engaged or can be disassembled, further improving operational convenience.

[0013] Furthermore, the grinding through hole is provided with a first locking portion, and the grinding sleeve assembly is provided with a second locking portion. When the grinding sleeve assembly is installed on the grinding through hole, the first locking portion and the second locking portion engage. Through the cooperation of the first locking portion and the second locking portion, the grinding sleeve assembly can be installed on the grinding through hole. When it is necessary to remove the grinding sleeve assembly for cleaning or replacement of parts, simply rotate the grinding sleeve assembly to disengage the first locking portion and the second locking portion to remove the grinding sleeve assembly.

[0014] Furthermore, the first engaging portion is disposed on the outer side wall of the grinding through hole, and has an installation opening and an installation stop arm. The installation opening is used to engage with the second engaging portion, and the installation stop arm is used to restrict the position of the second engaging portion, preventing insufficient or excessive rotation of the grinding sleeve assembly from causing the first engaging portion and the second engaging portion to not be fully engaged, thereby achieving stable installation of the grinding sleeve assembly and the grinding through hole. When the grinding sleeve assembly is installed on the grinding through hole, the second engaging portion engages with the first engaging portion through the installation opening. When the second engaging portion is fully engaged with the first engaging portion, one end of the second engaging portion abuts against the installation stop arm.

[0015] Furthermore, a snap-fit ​​arm is provided on the outer side of the grinding sleeve assembly, and the second snap-fit ​​portion is disposed on the snap-fit ​​arm. Even further, the second snap-fit ​​portion is disposed on the inner side of the snap-fit ​​arm, and the snap-fit ​​arm configuration allows for a more secure engagement between the first snap-fit ​​portion and the second snap-fit ​​portion.

[0016] Furthermore, there are three first snap-fit ​​parts, evenly distributed on the outer wall of the grinding through hole, and three snap-fit ​​arms, located on the outer side of the grinding sleeve assembly corresponding to the first snap-fit ​​parts. The number of three and their even distribution ensure a stable connection.

[0017] Furthermore, the shape of the second snap-fit ​​portion can be straight, L-shaped, or circular.
