[0002] In daily life, people often use grinders to process ingredients such as coffee beans, pepper, and cinnamon to ensure that the ingredients can have the best flavor when eaten or cooked. Currently common grinders mainly rely on the mutual movement between the grinding head and the grinding sleeve to grind the ingredients. However, the mutual movement between the grinding head and the grinding sleeve of the existing grinder needs to be connected to the transmission shaft of the external power mechanism, which makes it difficult to completely disassemble the grinding head, grinding sleeve and other parts, and there is a problem of being unable to completely clean. Therefore, the remaining powder may cause odor after long-term accumulation, which in turn causes hygiene problems. At the same time, the grinding head and the grinding sleeve may be worn after long-term use, which is not convenient for replacing new grinding heads and grinding sleeves. Summary of the invention

[0003] The purpose of the present invention is to solve the technical problems that the existing grinders cannot be completely cleaned and the grinding heads and grinding sleeves are difficult to replace. To solve the above problems, the present invention provides a grinding barrel, the grinding heads and grinding sleeves of which can be disassembled, so that the user can easily clean the grinding barrel or replace the worn grinding heads or grinding sleeves.

[0004] The present invention specifically adopts the following technical solutions:

[0005] A grinding barrel, characterized in that it comprises a shell, a grinding head, a grinding sleeve assembly, a connecting seat, a base, a grinding head seat assembly and a fixing assembly; the shell is detachably connected to the connecting seat, and the shell and the connecting seat together form a food accommodating space; a grinding through hole is provided in the connecting seat, and the grinding sleeve assembly is detachably mounted on the grinding through hole; the connecting seat is rotatably connected to the base; the base is provided with a fixing column, and the grinding head seat assembly is sleeved on the fixing column; the grinding head is mounted on the grinding head seat assembly, and the grinding head is located in the grinding through hole, and together with the grinding sleeve assembly, forms a food grinding space, and the food grinding space is communicated with the food accommodating space; the fixing assembly is arranged below the grinding head seat assembly and is detachably connected to the base.

[0006] When the grinding barrel is working, the food to be ground is placed in the food holding space and falls into the food grinding space connected to the food holding space. At this time, the shell is rotated manually or by an external power mechanism, and the shell drives the grinding sleeve assembly installed on the connecting seat to rotate through the connecting seat. At this time, the base and the grinding head seat assembly and the grinding head installed on the base remain stationary. At this time, the grinding head and the grinding sleeve assembly rotate relative to each other, thereby grinding the food to be ground in the food grinding space. When it is necessary to clean or replace the grinding head or the grinding sleeve, it is only necessary to disassemble the fixing assembly to separate the grinding head seat assembly and the grinding head. At the same time, the grinding sleeve assembly and the connecting seat are also detachably connected. After separating the grinding head seat assembly and the grinding head, the grinding sleeve assembly can be further removed to achieve the overall disassembly of the grinding head and the grinding sleeve assembly.

Through the cooperation between the first clamping portion and the second clamping portion, the grinding sleeve assembly can be installed on the grinding through hole. When the grinding sleeve assembly needs to be removed for cleaning or replacement of parts, it is only necessary to rotate the grinding sleeve assembly to release the clamping of the first clamping portion and the second clamping portion, and the grinding sleeve assembly can be removed.

[0009] Furthermore, the first clamping part is arranged 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 be clamped with the second clamping part, and the installation stop arm is used to limit the position of the second clamping part to prevent the grinding sleeve assembly from under-rotating or over-rotating, resulting in the first clamping part and the second clamping part not being fully engaged, so as to achieve 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 clamping part is clamped into the first clamping part through the installation opening, and when the second clamping part is completely clamped into the first clamping part, one end of the second clamping part abuts against the installation stop arm.

[0010] Furthermore, a clamping arm is arranged on the outer side of the grinding sleeve assembly, and the second clamping part is arranged on the clamping arm. Furthermore, the second clamping part is arranged on the inner side of the clamping arm, and the arrangement of the clamping arm can make the clamping of the first clamping part and the second clamping part more firmly.

[0011] Furthermore, the number of the first clamping parts is 3 and evenly distributed on the outer wall of the grinding through hole, and the number of the clamping arms is 3 and arranged on the outer side of the grinding sleeve assembly corresponding to the first clamping part.
