Stone pulverizing rods are relatively easier to operate, but they often break during use.
[0004] In addition, during the crushing process, garlic cloves will splatter outside, causing waste and polluting the environment. Furthermore, the garlic smell will spread outside, which is very pungent and inconvenient for people.
[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention
[0006] This invention addresses the aforementioned problems in the prior art by proposing a crusher that helps reduce manufacturing costs, improve crushing efficiency, stabilize the counterweight, and ensure stable operation.
[0007] To achieve the above-mentioned objectives, the present invention employs the following technical solution:
[0008] A crusher, comprising:
[0009] Crush the cup;
[0010] A crushing hammer, which has a hammer shell and a counterweight located inside the hammer shell;
[0011] The hammer shell has an upper shell and a lower shell that are fixedly assembled. The upper shell has an upper limit rib that blocks the upper end of the counterweight. The counterweight is located in the lower part of the hammer shell.
[0012] In some embodiments of this application, the lower end of the counterweight is located inside the lower shell.

[0015] In some embodiments of this application, a plurality of side limiting ribs extending inward and located on the inner wall of the lower shell and on the outside of the counterweight are provided.
[0016] In some embodiments of this application, the lower support rib is disposed on the bottom of the inner cavity of the lower shell, and the lower support member is connected to the side limiting rib.
[0017] In some embodiments of this application, a plurality of upper limit ribs extending radially inward are provided on the inner wall of the upper shell.
[0018] In some embodiments of this application, the bottom of the lower shell is a concave surface, and a plurality of crushing protrusions are provided on the concave surface.
[0019] In some embodiments of this application, an assembly and fixing structure is provided between the upper end of the upper shell and the lower end of the lower shell. The assembly and fixing structure has an outer edge sleeve provided on one of the upper shell and the lower shell, and a receiving groove provided on the other of the upper shell and the lower shell and matched with the outer edge sleeve. A raised sealing protrusion is provided on the inner side of the outer edge sleeve and / or the groove wall of the receiving groove.
[0020] In some embodiments of this application, a cup lid covering the upper opening of the pounding cup is also included, with an opening on the cup lid for the pounding hammer to extend into.

[0052] See Figures 1-11This is the first embodiment of a crusher proposed in this utility model. A crusher 100 includes a crushing cup 10 and a crushing hammer 20. Food or items to be crushed are placed in the crushing cup 10, and the crushing operation is performed using the crushing hammer 20. The crushing hammer 20 has a hammer shell 21 and a counterweight 22 located inside the hammer shell 21. The hammer shell 21 has an upper shell 211 and a lower shell 212 that are fixedly mounted. The upper shell 211 is provided with an upper limit rib 2111 that abuts against the upper end of the counterweight 22, thereby limiting the degree of freedom of the counterweight 22 to move upward. The counterweight 22 is located in the lower part inside the hammer shell 21, and of course, the center of gravity of the counterweight 22 is located in the lower part inside the hammer shell 21.
[0053] In this embodiment, the hammer shell 21 is assembled from a split upper shell 211 and a lower shell 212, which can be injection molded, thus reducing manufacturing costs. A counterweight 22 is installed inside the hammer shell 21. Firstly, the counterweight 22 increases the overall weight of the crushing hammer 20, utilizing gravitational potential energy to assist in crushing, making operation easier. Secondly, the lowered center of gravity causes the crushing hammer 20 to generate a greater vertical impact force during its descent, as well as a greater swing amplitude, improving crushing efficiency. An upper limit rib 2111 inside the upper shell 211 blocks the upper end of the counterweight 22, keeping it fixed during crushing and ensuring smooth and precise crushing action.
[0054] In some embodiments of this application, the lower end of the counterweight 22 is located inside the lower shell 212. A lower support rib 2121 is provided inside the lower shell 121 to support the lower end of the counterweight 22, limiting the degree of freedom for downward movement of the counterweight 22. Preferably, the lower support rib 2121 is located on the bottom of the inner cavity of the lower shell 212. The lower support rib 2121 directly supports the lower end of the counterweight 22, and together with the upper limit rib 2111 of the upper shell 211, forms a "clamping" fixed structure, preventing the crushing hammer 20 from becoming unbalanced due to the shaking of the counterweight 22 during crushing, thus making the crushing action more stable. The lower support rib 2111 serves as a positioning reference, allowing the counterweight 22 to be placed directly on the bottom of the lower shell 212 during assembly without complex calibration, which improves assembly efficiency. The lower support rib 2121 directly transmits the weight of the counterweight 22 to the lower shell 212, making the impact force of the crushing hammer 20 more concentrated when it falls, which improves crushing efficiency.
[0055] In some embodiments of this application, both the upper shell 211 and the lower shell 212 of the outer casing 21 are injection molded, and the counterweight 22 can be cylindrical or columnar. The material of the counterweight 22 has a higher specific gravity than that of the outer casing 21. The outer casing 21 can be made of plastic; the counterweight 22 is made of metal, preferably stainless steel. The high-density counterweight 22 is located at the lower part of the hammer body 21. Combined with the lightweight outer casing 21, this results in a lower center of gravity for the crushing hammer 20, a smaller swing amplitude during crushing, more precise and controllable operation, and avoids the splashing of crushed particles.
[0056] In some embodiments of this application, a plurality of inwardly extending side limiting ribs 2122 are provided on the inner wall of the lower shell 212. These side limiting ribs 2122 are located outside the counterweight 22 and are used to limit the circumferential movement of the counterweight 22. The side limiting ribs 2122 provide circumferential positioning for the counterweight, ensuring that the gravity of the counterweight 22 is transmitted vertically, and that the impact force is concentrated at the bottom of the hammer shell 21 during crushing. This is beneficial for improving crushing efficiency.
[0057] In some embodiments of this application, a plurality of inwardly extending side limiting ribs 2122 are provided circumferentially spaced on the inner wall of the lower shell 212, and the side limiting ribs 2122 extend vertically. A plurality of circumferentially spaced lower support ribs 2121 are provided at the bottom of the inner cavity of the lower shell 212; the lower support ribs 2121 are connected to the side limiting ribs 2122. The lower support ribs 2121 and the side limiting ribs 2122 are integrally formed with the lower shell 212 through injection molding, thereby improving structural strength.
[0058] In some embodiments of this application, a plurality of upper limit ribs 2111 extending radially inward are provided on the inner wall of the upper shell 211, and the plurality of upper limit ribs 2111 are spaced apart in the circumferential direction. The circumferential spacing of the upper limit ribs 2111 provides a top positioning reference for the counterweight 22, and the upper limit ribs 2111 and the upper shell 211 are integrally injection molded.
[0059] In some embodiments of this application, the lower shell 212 has a structure that is narrower at the top and wider at the bottom, which helps to increase the area of the bottom surface of the lower shell 212. The bottom of the lower shell 212 is a concave surface 2123, on which multiple crushing protrusions 2124 are provided. By setting the concave surface 2123, an encapsulating structure can be formed to prevent the crushing powder from splashing.
[0060] In some embodiments of this application, an assembly and fixing structure is provided between the upper end of the upper shell 211 and the lower end of the lower shell 212 to achieve a fixed assembly between the upper shell 211 and the lower shell 212. The assembly and fixing structure has an outer edge sleeve 2125 provided on the lower shell 212 and a receiving groove 2115 provided on the upper shell 211. The receiving groove 2115 is matched with the outer edge sleeve 2125, and the outer edge sleeve 2125 extends into the receiving groove 2115. A raised sealing protrusion 2116 is provided on the groove wall of the receiving groove 2115. The outer edge sleeve 2125 and the sealing protrusion 2116 are interference-fitted, so that the outer edge sleeve 2125 is tightly fixed at the receiving groove 2115. The sealing protrusion 2116 is arranged in a ring shape, which can also achieve a seal between the upper shell 211 and the lower shell 212, forming a sealed hammer shell 21.
[0061] In some other embodiments of this application, an outer edge sleeve may be provided on the upper shell 211, or a raised sealing protrusion may be provided on the inner side of the outer edge sleeve 2125.
[0062] In some embodiments of this application, the crusher 100 further includes a lid 30 covering the upper opening of the crushing cup 10, with an inlet 34 for the crushing hammer 20 to extend into it. The lid 30 has a cover body 31 extending upward in an inward direction, a reinforcing edge 32 at the inner end of the cover body 31, and a reinforcing edge 33 at the outer end of the cover body 31. The reinforcing edge 32 surrounds and forms the inlet 34. By providing the reinforcing edge 32, it is beneficial to ensure structural strength and withstand the friction of the crushing hammer 20 moving up and down within the inlet 34.
[0063] In some embodiments of this application, the reinforcing edge 32 has an annular upper reinforcing edge 321, an inner reinforcing edge 322 extending downwardly along the inner side of the upper reinforcing edge 321, and an outer reinforcing edge 323 connecting the outer side of the upper reinforcing edge 321 and the cover 31. The upper reinforcing edge 321 forms a top annular beam, and the inner reinforcing edge 322 and the outer reinforcing edge 323 provide support from the inner and outer sides, respectively, increasing the structural strength of the reinforcing edge 32. The inner reinforcing edge 322 extends vertically along the inner side of the inlet 324, forming a rigid guide channel, which reduces the swing amplitude of the hammer during crushing and ensures that the impact force acts perpendicularly on the food. The outer reinforcing edge 323 extends upwardly in an inward direction.
[0064] In some embodiments of this application, the reinforcing edge 33 has a radial reinforcing edge 331 extending radially outward along the outer end of the cover 31, and an outer reinforcing edge 332 that is bent tangentially and inclined outward along the outer end of the radial reinforcing edge 331. The radial reinforcing edge 331 is located above the upper edge of the crushing cup 10, and the outer reinforcing edge 332 covers the outer side of the upper edge of the crushing cup 10. The inclined angle of the outer reinforcing edge 332 is designed to form a guide slope, which automatically aligns with the cup edge during installation without the need for precise alignment.
[0065] In some embodiments of this application, a plurality of upwardly convex strip-shaped protrusions 11 are provided at the bottom of the cavity of the crushing cup 10. Each protrusion module has multiple parallel strip-shaped protrusions 11, and the strip-shaped protrusions 11 of two adjacent modules are not parallel. Adjacent protrusion modules are staggered at an angle of 30°-45°. When the food is squeezed by the crushing hammer, the protrusions in different directions generate shearing forces, tearing the fibrous tissue in multiple directions, thus shortening the crushing time compared to traditional parallel protrusions.
[0066] In some embodiments of this application, a holding dish 40 can be provided as needed. The masher 100 includes a mash cup 10, a mash hammer 20, a cup lid 30, and a holding dish 40. Food or items to be mashed are placed in the mash cup 10, and the cup lid 30 covers the upper opening of the mash cup 10 to prevent the mashed powder from splashing. The mash hammer 20 is used for mashing. The mash hammer 20 has a hammer shell 21 and a counterweight 22 located inside the hammer shell 21. The hammer shell 21 has an upper shell 211 and a lower shell 212 that are fixedly mounted. The upper shell 211 is provided with an upper limit rib 2111 that blocks the upper end of the counterweight 22. The upper limit rib 2111 abuts against the upper end of the counterweight 22 to limit the degree of freedom of the counterweight 22 to move upward. The center of gravity of the counterweight 22 is located in the lower part inside the hammer shell 21.
[0067] In some embodiments of this application, the holding dish 40 can be stacked under the mortar 10, which helps to reduce space occupation. The holding dish 40 adopts a shallow dish-shaped design, which can be used to hold the crushed powder in the mortar 10, and can also be used in conjunction with the mortar hammer 20 to perform grinding. Multiple upward-protruding grinding protrusions 41 are provided on the bottom of the cavity of the holding dish 40. The grinding protrusions 41 are pyramidal in shape. When the food is hammered, the protrusions in different directions generate shear force, which helps to improve grinding efficiency. It is suitable for making ingredients that need to be ground, such as chili powder and crushed peanuts. At the same time, it can also be served directly as a dipping sauce dish, reducing the use of tableware and improving kitchen operation efficiency.
