Description

Technical Field

[0001] The present invention relates to the technical field of household kitchen utensils, and particularly relates to a crusher for kitchen use. Background Art

[0002] Seasonings can emit certain odors and can change the flavor of food, and are often used by people during food cooking. However, the original seasonings are relatively large in volume, either in the shape of leaves, large particles, or other irregular shapes. When in use, they need to be ground into fine particles so that the fragrance can better blend into the food. Although the fine-particle seasonings are more easily flavored, their shelf life is short.

[0003] For household seasonings, in order to enjoy the flavor of seasonings and extend the shelf life of seasonings, people mostly use grinders or crushers to crush large pieces of seasonings into fine particles for use. Seasonings include salt, spices, dried fruits, peppers, peppers, etc. However, due to the limitations of their own structures during use, some existing grinders or crushers are only suitable for grinding small-sized seasonings, and some are only suitable for grinding large-sized seasonings, with poor versatility. Moreover, generally, the grinding components are directly installed in the cylinder body, occupying a large space, and the cylinder body is mostly provided with a partition structure, so that the amount of seasonings that can be contained is small, and seasonings need to be added frequently, and the usage capacity is too small.

[0004] In addition, due to the different weights of seasonings themselves, light-weight seasonings are not easy to fall down during grinding. For example, vanilla, coriander, etc. Therefore, the grinding blades can only grind the seasonings below, and it is difficult to make the seasonings above fall down for grinding, which easily leads to empty grinding, the seasonings cannot be taken over, resulting in uneven grinding and sprinkling of seasonings and affecting the food flavor. Summary of the Invention

[0005] Aiming at the current situation of the above-mentioned existing technologies, the technical problem to be solved by the present invention is to provide a crusher for kitchen use, which has a large capacity and can squeeze seasonings to the grinding components for full grinding while grinding, ensuring that seasonings of various weights can easily fall to the grinding components for grinding, and avoiding empty grinding of the grinding components caused by the lack of supply of seasonings.

[0006] The technical solution adopted by the present invention to solve the above technical problems is as follows: A crusher for kitchen use includes a material cylinder with an inner cavity, a grinding component installed at the lower end of the material cylinder, an elastic pressing component installed in the inner cavity of the material cylinder for squeezing seasonings to the grinding component, a locking ring clamped at the upper end of the material cylinder for locking and pressing the elastic pressing component, and a housing sleeved on the outer wall of the material cylinder and relatively rotating with the material cylinder. The housing is connected to the grinding component through a fixing ring and drives the grinding component to rotate synchronously.

[0007] Further, an upper cover is provided at the upper end of the locking ring, and the upper cover rotates synchronously with the locking ring. The lower end of the locking ring is rotationally engaged with the upper end of the outer shell.

[0008] Further, the elastic pressing assembly includes a hollow pressing block, a spring, and a hollow connecting seat. The pressing block is slidably engaged with the connecting seat to form a chamber for accommodating the spring. The spring is disposed in the chamber formed by the cooperation of the pressing block and the connecting seat. One end of the spring abuts against the bottom of the pressing block, and the other end abuts against the top of the connecting seat.

[0009] Further, a plurality of equally spaced chutes are recessed on the outer peripheral wall of the pressing block. An inclined guide block is provided at the upper end of the chute. A guide groove slidably engaged with the chute is provided on the inner peripheral wall of the connecting seat, and a limiting portion engaged with the inclined guide block is provided at the end of the guide groove.

[0010] Further, at least one first water outlet hole penetrating the chamber is opened near the bottom on the side wall of the pressing block, and at least one second water outlet hole penetrating the chamber is opened near the top on the side wall of the connecting seat. There are gaps between the outer walls of the pressing block and the connecting seat and the inner wall of the barrel.

[0011] Further, a plurality of convex teeth are densely arranged on the outer end surface of the bottom of the pressing block.

[0012] Further, a limiting edge extending outward is provided at the top of the connecting seat, and the limiting edge abuts against the upper edge of the barrel.

[0013] Further, the grinding assembly includes a rotating shaft, a sweeping wheel, a fixed blade, a moving blade, a retaining ring, and a nut. The sweeping wheel, the fixed blade, the moving blade, and the retaining ring are sequentially strung on the rotating shaft from top to bottom and axially limited by tightening the nut. A connecting groove for embedding the nut is provided at the center of the fixed ring, and a plurality of card slots are opened on the outer peripheral wall of the fixed ring. A clamping block engaged with the card slot is provided on the inner peripheral wall of the outer shell.

[0014] Further, a plurality of equally spaced protruding portions are convexly provided downward at the bottom of the barrel. A groove engaged with the protruding portion is provided in the circumferential direction of the fixed blade, and a circular hole connected to the rotating shaft is opened at the center of the fixed blade. Square holes connected to the rotating shaft are opened at the centers of the sweeping wheel, the moving blade, and the retaining ring.

[0015] Further, a first annular convex edge is convexly provided on the outer wall of the barrel, and a second annular convex edge abuting against the first annular convex edge is convexly provided on the inner wall of the outer shell.

[0016] Compared with the prior art, the advantages of the present invention are as follows: The present invention squeezes seasonings to the grinding component for grinding through an elastic pressing component. The seasonings can be accommodated in a barrel without partitions, increasing the capacity and preventing seasoning blockage. Moreover, during grinding, as the seasonings are consumed, the elastic pressing component always presses the remaining seasonings to supplement to the grinding component, enabling seasonings of various weights to smoothly fall to the grinding component for grinding, without material detachment, and making it more convenient for users to operate. They only need to apply force to twist for grinding without applying force to press and supplement seasonings. Additionally, the grinding component is arranged at the lower end of the barrel, reducing the space occupied by the grinding component in the barrel and further expanding the capacity of the barrel to fill seasonings. It can be used for grinding seasonings of large and small sizes, with good versatility and convenient use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0024] As Figure 1-6As shown in the figure, a crusher for kitchen use includes a barrel 1 with an inner cavity, a grinding assembly installed at the lower end of the barrel 1, an elastic pressing assembly installed in the inner cavity of the barrel 1 for extruding seasonings to the grinding assembly, a lock ring 2 clamped at the upper end of the barrel 1 for locking and pressing the elastic pressing assembly, and a housing 3 sleeved on the outer wall of the barrel 1 and rotatable relative to the barrel 1. The housing 3 is connected to the grinding assembly through a fixing ring 4 and drives the grinding assembly to rotate synchronously.

[0025] In the present invention, seasonings are extruded to the grinding assembly by the elastic pressing assembly for grinding. The seasonings can be accommodated in the barrel 1 without partitions, increasing the capacity and preventing seasoning blockage. Moreover, during grinding, as the seasonings are consumed, the elastic pressing assembly always presses the remaining seasonings to supplement to the grinding assembly, enabling seasonings of various weights to smoothly fall to the grinding assembly for grinding, without material detachment, and making it more convenient for users to operate. They only need to apply force to twist for grinding without having to apply force to press and supplement seasonings. In addition, the grinding assembly is arranged at the lower end of the barrel 1, reducing the space occupied by the grinding assembly in the barrel 1 and further expanding the capacity of the barrel 1 for filling seasonings. It can be applicable to grinding seasonings of large and small sizes, with good versatility and convenient use.

[0026] An upper cover 5 is provided at the upper end of the lock ring 2, and the upper cover 5 rotates synchronously with the lock ring 2. The lower end of the lock ring 2 is rotationally matched with the upper end of the housing 3. By screwing the upper cover 5, the lock ring 2 can be driven to rotate synchronously. The lock ring 2 and the housing 3 rotate relative to each other. A plurality of anti-slip portions 5.1 are evenly arranged in the circumferential direction at the upper end of the upper cover 5, which is convenient for hand holding, increases friction, can prevent slipping when the hands are wet, and provides a comfortable grip, meeting the ergonomic design.

[0027] The elastic pressing assembly includes a hollow pressing block 6, a spring 7, and a hollow connecting seat 8. The pressing block 6 is slidably matched with the connecting seat 8 to form a chamber for accommodating the spring 7. The spring 7 is arranged in the chamber formed by the cooperation of the pressing block 6 and the connecting seat 8. One end of the spring 7 abuts against the bottom of the pressing block 6, and the other end abuts against the top of the connecting seat 8. The setting of the spring 7 enables the elastic pressing assembly to be compressed when subjected to an external force, and the pressing block 6 and the connecting seat 8 slide relative to each other. The pressing block 6 contracts into the connecting seat 8, and the volume of the elastic pressing assembly shortens. After the external force disappears, the spring 7 resets and pushes the pressing block 6 and the connecting seat 8 to slide relative to each other. The pressing block 6 extends out of the connecting seat 8, but they do not separate from each other, and the volume of the elastic pressing assembly elongates. By utilizing the elastic action of the spring 7, the elastic pressing assembly can always press the remaining seasonings to the grinding assembly during the wear and tear of seasoning grinding, timely supplementing the seasonings.

[0028] A plurality of sliding grooves 6.1 arranged at equal intervals are recessed on the outer peripheral wall of the pushing block 6. An inclined guide block 6.2 is provided at the upper end of the sliding groove 6.1. A guide groove 8.1 that is slidably matched with the sliding groove 6.1 is provided on the inner peripheral wall of the connecting seat 8. A limiting portion 8.2 that is matched with the inclined guide block 6.2 is provided at the end of the guide groove 8.1. The guide groove 8.1 is slidably connected in the sliding groove 6.1. When the pushing block 6 and the connecting seat 8 slide relative to each other, the cooperation between the guide groove 8.1 and the sliding groove 6.1 plays a guiding role. When the spring 7 resets and the pushing block 6 extends out of the connecting seat 8, the limiting portion 8.2 can resist the inclined guide block 6.2 to prevent the pushing block 6 from disengaging from the connecting seat 8. When assembling the pushing block 6 and the connecting seat 8, the inclined guide block 6.2 has a guiding effect and can easily slide over the limiting portion 8.2 and be slidably connected with the guide groove 8.1.

[0029] At least one first water outlet hole 6.3 that penetrates the chamber is opened on the side wall of the pushing block 6 near the bottom. At least one second water outlet hole 8.3 that penetrates the chamber is opened on the side wall of the connecting seat 8 near the top. There are gaps between the outer walls of the pushing block 6 and the connecting seat 8 and the inner wall of the barrel 1. When using a dishwasher or other cleaning tools to clean the crusher, it is convenient for the cleaning liquid to enter and exit the elastic pushing assembly, which is convenient for cleaning and draining, and can prevent the cleaning liquid from staying in the pushing block 6 and the connecting seat 8, thus affecting the user experience.

[0030] A number of convex teeth 6.4 are densely arranged on the outer end surface at the bottom of the pushing block 6, which can increase friction and prevent slipping during grinding. Since seasonings include dry materials and wet materials, dry materials have less moisture and are brittle and easy to grind after drying, while wet materials such as herbs and coriander contain more moisture and are prone to water leakage during grinding. If ground with water, the seasonings are likely to rotate with the grinding assembly, thus affecting grinding. The setting of the convex teeth 6.4 can increase friction and play an anti-slip role. When the grinding assembly grinds, it can prevent the seasonings from being rotated by the grinding assembly. The seasonings will be subjected to the thrust of the spring 7 pushing the pushing block 6 and the radial resistance of the convex teeth 6.4 to ensure that the wet materials can be smoothly ground.

[0031] A limiting edge 8.4 extending outward is provided at the top of the connecting seat 8, and the limiting edge 8.4 abuts against the upper edge of the barrel 1. The setting of the limiting edge 8.4 enables the limiting edge 8.4 to be pressed between the connecting end faces of the locking ring 2 and the barrel 1 when the locking ring 2 is connected to the barrel 1, thereby restricting the axial position of the elastic pushing assembly and preventing it from moving freely in the barrel.

[0032] The grinding assembly includes a rotating shaft 9, a sweeping wheel 10, a fixed blade 11, a moving blade 12, a retaining ring 13 and a nut 14. The sweeping wheel 10, the fixed blade 11, the moving blade 12 and the retaining ring 13 are sequentially connected in series on the rotating shaft 9 from top to bottom and axially limited by tightening with the nut 14. At the upper end of the rotating shaft 9, a resisting portion 9.1 protrudes radially along the rotating shaft 9 to limit the upper end of the sweeping wheel 10. The resisting portion 9.1 and the nut 14 axially limit the upper and lower positions of the sweeping wheel 10, the fixed blade 11, the moving blade 12 and the retaining ring 13 connected in series on the rotating shaft 9, thereby assembling the grinding assembly into an independent structure with a small volume and reduced space occupation. Moreover, the sweeping wheel 10, the fixed blade 11, the moving blade 12 and the retaining ring 13 are convenient to clean and replace. A connecting groove 4.1 for embedding the nut 14 is provided at the center of the fixing ring 4, so that the fixing ring 4 rotates synchronously with the rotating shaft 9. A plurality of card slots 4.2 are formed on the outer peripheral wall of the fixing ring 4, and a clamping block 3.1 engaged with the card slots 4.2 is provided on the inner peripheral wall of the outer shell 3, so that the outer shell 3 rotates synchronously with the fixing ring 4.

[0033] A plurality of convex portions 1.1 arranged at equal intervals protrude downward from the bottom of the material cylinder 1. A groove 11.1 matched with the convex portions 1.1 is provided in the circumferential direction of the fixed blade 11, so that the fixed blade 11 rotates synchronously with the material cylinder 1. A circular hole connected to the rotating shaft 9 is formed at the center of the fixed blade 11, that is, the rotation of the rotating shaft 9 will not drive the fixed blade 11 to rotate. Square holes connected to the rotating shaft 9 are formed at the centers of the sweeping wheel 10, the moving blade 12 and the retaining ring 13, that is, the rotation of the rotating shaft 9 can drive the sweeping wheel 10, the moving blade 12 and the retaining ring 13 to rotate synchronously, so that the moving blade 12 rotates in the opposite direction to the fixed blade 11, thereby cutting and grinding the seasoning. A plurality of arc-shaped knife grooves arranged at equal intervals are provided on both the moving blade 12 and the fixed blade 11, and a plurality of knife teeth are provided in the arc-shaped knife grooves. As the moving blade 12 and the fixed blade 11 rotate in opposite directions, the arc-shaped knife grooves on the moving blade 12 and the arc-shaped knife grooves on the fixed blade 11 cross-cut and grind the seasoning. The setting of the sweeping wheel 10 plays a role in stirring the material to prevent the seasoning from clogging at the grinding assembly. The setting of the retaining ring 13 plays an auxiliary installation role, which is convenient for tightening and fixing the nut 14.

[0034] A first annular convex edge 1.2 protrudes from the outer wall of the material cylinder 1. A second annular convex edge 3.2 abutted against the first annular convex edge 1.2 protrudes from the inner wall of the outer shell 3. The outer shell 3 is sleeved on the material cylinder 1, and the outer shell 3 is axially limited by the cooperation of the first annular convex edge 1.2 and the second annular convex edge 3.2, and the outer shell 3 can rotate relative to the material cylinder 1.

[0035] In addition, the lock ring 2 and the material cylinder 1 are mutually clamped. The clamping structure can adopt snap connection or can adopt the cooperation connection of a lock block and a lock groove, that is, it can ensure that the lock ring 2 rotates synchronously with the material cylinder 1.

[0036] In use, first load the seasoning into the cartridge 1, then insert the elastic pressing component into the cartridge 1, install the lock ring 2 and the upper cover 5. Then, hold the upper cover 5 with one hand and hold the outer shell 3 with the other hand, and twist them in opposite directions. The upper cover 5 drives the lock ring 2, the cartridge 1, and the fixed blade 11 to rotate synchronously. The outer shell 3 drives the fixed ring 4, the nut 14, the rotating shaft 9, the moving blade 12, the sweeping wheel 10, and the snap ring 13 to rotate synchronously. The fixed blade 11 and the moving blade 12 rotate in opposite directions to cut and grind the seasoning. As the seasoning is consumed and its volume decreases, the elastic pressing component automatically pushes the pressing block 6 downward under the action of the spring 7 to squeeze the seasoning, ensuring that the grinding component is always filled with seasoning. The operation is labor-saving, ensuring that seasonings of various weights can easily fall to the grinding component for grinding, and avoiding the grinding component running empty due to the disconnection of the seasoning.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
