Description

Technical Field

[0001] The present disclosure relates to the technical field of grinders, and in particular to a grinder. Background Art

[0002] The function of a grinder is to grind granular condiments such as pepper and salt into powder, making the flavor of these condiments more abundant. There are various small grinders for grinding condiments on the market. Powdered condiments are more convenient to use and have a stronger flavor than granular or block condiments. However, powdered condiments are more likely to absorb moisture, making them difficult to store for a long time, and their flavor is easily lost, affecting the taste. This requires condiments to be ground and used immediately.

[0003] For example, the utility model patent with application number 202221965348.0 discloses a kitchen grinder, including a male grinding head and a female grinding head, wherein the male grinding head is rotatably fitted in the female grinding head, an adjusting rod is connected to the male grinding head, the male grinding head is slidably connected to the adjusting rod up and down, and a reset piece made of soft rubber is arranged on the periphery of the adjusting rod, and the reset piece is used to reset the male grinding head. In the process of grinding with the grinder, the material can easily enter the gap at the connection between the upper shell and the lower shell. For some materials with higher hardness, such as salt, after entering the gap at the connection between the upper shell and the lower shell, when the upper and lower shells are rotated, the salt particles in the gap will rub back and forth in the gap, which will not only cause the upper and lower shells at this position to be worn by the salt particles, but also cause the worn debris to fall down and mix with the material, which is not conducive to human health.

[0030] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is described in detail, clearly and completely in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not used to limit the present disclosure.

[0031] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0032] Please see Figure 1 , Figure 3 , Figure 4 As shown, the present disclosure provides a grinder, which is roughly a cylindrical structure, including an upper shell 1 and a lower shell 2, the upper shell 1 is covered on the lower shell 2, and a feeding mechanism 8 is provided at one end of the upper shell 1 away from the lower shell 2, and the feeding mechanism 8 is used to hold materials to be ground, and an end cover 3 is provided at one end of the lower shell 2 away from the upper shell 1, a feeding channel is provided in the upper shell 1, and a grinding mechanism for grinding materials is provided in the lower shell 2, and the materials in the feeding mechanism 8 enter the grinding mechanism through the feeding channel, and an anti-wear structure is provided at the relative rotation position of the upper shell 1 and the lower shell 2, and the anti-wear structure includes a first anti-wear part 9 and a second anti-wear part 10, the first anti-wear part 9 is in contact with the lower end of the upper shell 1 to prevent materials from entering between the first anti-wear part 9 and the upper shell 1, and the second anti-wear part 10 is provided on the lower shell 2, and the upper edge of the second anti-wear part 10 is in contact with the first anti-wear part 9 to prevent materials from entering between the first anti-wear part 9 and the second anti-wear part 10. In this way, it is possible to effectively prevent materials from entering between the upper shell 1 and the lower shell 2, and prevent materials from rubbing back and forth at the relative rotation point when the upper shell 1 and the lower shell 2 rotate relative to each other. In order to be more wear-resistant, the first anti-wear member 9 is made of metal, and the second anti-wear member 10 is made of metal or ceramic.

[0033] Please also see Figure 5 and Figure 8As shown, further, the cross section of the first anti-wear member 9 is an "L"-shaped layered structure, and the first anti-wear member 9 includes an upper portion 18 and a lower portion 19, the first side of the upper portion 18 is in contact with the inner peripheral wall of the upper shell 1, the second side of the upper portion 18 is in contact with the upper edge of the second anti-wear member 10, and the lower portion 19 is in contact with the lower end of the upper shell 1. Specifically, the upper edge of the second anti-wear member 10 is lower than the top of the first anti-wear member 9, and the contact point between the upper edge of the second anti-wear member 10 and the first anti-wear member 9 is lower than the top of the first anti-wear member 9. Such a setting can further prevent the material from entering between the first anti-wear member 9 and the upper shell 1. Preferably, the second anti-wear member 10 is provided with a protrusion 14, which is in contact with the second side of the upper portion 18 of the first anti-wear member 9, and the second anti-wear member 10 is provided with a guide structure 15, which is used to guide the material in the feed channel to the grinding mechanism. The arrangement of the raised portion 14 makes the second anti-wear member 10 fit more closely with the first anti-wear member 9, thereby preventing the entry of materials. The flow guide structure 15 is a downward arc-shaped structure. When materials fall on the second anti-wear member 10, the flow guide structure 15 guides the materials into the grinding mechanism, thereby preventing the materials from accumulating on the second anti-wear member 10.

[0034] For further information, please also refer to Figure 7 As shown, the inner wall of the lower shell 2 is provided with a first annular protrusion 16, and the second anti-wear member 10 is fitted with the first annular protrusion 16. Preferably, the first annular protrusion 16 is provided with a downward first inclined surface structure 17, and the second anti-wear member 10 is provided with a second inclined surface structure, and the first inclined surface structure 17 is fitted with the second inclined surface structure. The arrangement of the first inclined surface structure 17 and the second inclined surface structure can increase the contact area between the second anti-wear member 10 and the first annular protrusion 16, so that the second anti-wear member 10 and the first annular protrusion 16 have better fit and are more tightly connected. The first inclined surface structure 17 is arranged downward to prevent materials from entering between the second anti-wear member 10 and the first annular protrusion 16.

[0035] In particular, a first gap 12 is provided between the second anti-wear member 10 and the first anti-wear member 9, and the first gap 12 is provided below the protrusion 14; a second gap 13 is provided between the second anti-wear member 10 and the inner peripheral wall of the lower shell 2; a third gap is provided between the lower portion 19 of the first anti-wear member 9 and the inner peripheral wall of the lower shell 2, and the first gap 12, the second gap 13 and the third gap are interconnected. Even if material enters between the first anti-wear member 9 and the second anti-wear member 10, due to the provision of the first gap 12, the material will enter the first gap 12 and the second gap 13 or the third gap, thereby avoiding friction between the material and the first anti-wear member 9 or the second anti-wear member 10. The upper shell 1 is disassembled from the lower shell 2, and the material entering between the first gap 12, the second gap 13 or the third gap can be directly shaken off manually, which is convenient to remove.

[0036] Please refer to Figure 2and Figure 3 As shown, the grinding mechanism includes a male grinding head 4 and a female grinding head 5. The male grinding head 4 is rotatably matched in the female grinding head 5. The male grinding head 4 is connected to an adjusting rod 6. The adjusting rod 6 and the upper shell 1 are injection molded as a whole. The male grinding head 4 and the adjusting rod 6 are connected in an upward and downward sliding manner. The male grinding head 4 and the female grinding head 5 are made of ceramic. The female grinding head 5 is roughly annular in structure. The male grinding head 4 is similar to a truncated cone structure. The female grinding head 5 includes a coarse grinding part and a fine grinding part. The coarse grinding part is above the fine grinding part. The inner circumferential wall of the coarse grinding part is provided with a plurality of first grinding teeth with spiral tooth lines. The inner circumferential wall of the fine grinding part is provided with a plurality of second grinding teeth with spiral tooth lines. The number of the second grinding teeth is greater than that of the first grinding teeth. The coarse grinding part performs coarse grinding on the material, and the fine grinding part performs fine grinding on the material. The outer circumferential wall of the male grinding head 4 is provided with a plurality of third grinding teeth with spiral tooth lines. The bottom surface of the tooth groove between adjacent third grinding teeth is an arc surface. The design of the arc surface makes it easier to guide the ground material, and also makes the grinding gap less likely to be blocked.

[0037] Furthermore, a working hole is provided at the center of the male grinding head 4, and the adjusting rod 6 is at least partially provided in the working hole. A first threaded section is provided at one end of the adjusting rod 6, and an adjusting member 7 is provided below the male grinding head 4. A blind hole is provided at the center of the adjusting member 7, and a second threaded section is provided in the blind hole. The first threaded section and the second threaded section are screwed together to adjust the male grinding head 4 to move up and down, thereby switching between fine grinding and coarse grinding of the material. An adjusting handle is provided on the adjusting member 7 for the convenience of the user to rotate.

[0038] Please also see Figure 6 As shown, further, a positioning member 11 for fixing the adjusting rod 6 is provided in the upper shell 1, and the upper shell 1 and the positioning member 11 are insert-molded, and a blind hole is provided on the positioning member 11, and the other end of the adjusting rod 6 is arranged in the blind hole. Specifically, the positioning member 11 is "cross-shaped" or "Y-shaped", and such a setting facilitates the entry of the material to be ground.

[0039] In particular, the portion of the adjusting rod 6 without the first threaded section is in the shape of a cube, and the working hole of the male grinding head 4 is also in the shape of a square. When the upper portion of the adjusting rod 6 enters the working hole, the inner circumferential wall of the working hole fits the cube shape of the adjusting rod 6. Such a setting limits the circumferential position of the male grinding head 4, making the structure more stable, thereby preventing the male grinding head 4 from rotating circumferentially with the adjusting rod 6, and further preventing the male grinding head 4 and the female grinding head 5 from rotating at the same time, which would result in failure of grinding.

[0040] It should be noted that when the grinder is used for grinding, the adjusting member 7 is rotated, and the adjusting member 7 will move upward along the adjusting rod 6, thereby driving the male grinding head 4 to move upward. Since the working hole is a square hole, the upper part of the adjusting rod 6 is a cube, so that the male grinding head 4 can only move upward and will not rotate circumferentially. With the rotation of the adjusting member 7 and the upward movement of the male grinding head 4, the particles of the ground material become finer and finer. In the process of grinding, as the material accumulates and the particles of the material are ground smaller and smaller, if the small particles enter between the first anti-wear member 9 and the second anti-wear member 10, they will eventually enter the second gap 13, and the upper shell 1 can be removed from the lower shell 2 to clean out the material. It effectively avoids the wear of the upper and lower shells 2 by the material particles and prolongs the service life. At the same time, there is no need to worry about the debris after wear falling down and mixing with the material to affect the health of the user.

[0041] The present application is described in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the present application and its core ideas. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
