Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, specifically relating to a tea crusher. Background Technology

[0002] In daily life, we often see small and convenient hand-cranked grinders, widely used in homes, shops, and other settings. These grinders are versatile; they can be used not only to grind dried fruit but are also commonly found in milk tea shops, where they are often used to grind tea leaves. By grinding the tea leaves into finer pieces, the flavor of the tea leaves can be fully released during brewing.

[0003] The aforementioned machines for pulverizing dried fruit and tea mainly consist of a handle for easy gripping and internal blades. The internal blades include fixed blades embedded in the machine body and rotating blades connected to the handle, with the fixed and rotating blades interlacing. When the user grips the handle and rotates it, the rotating blades rotate accordingly, working in conjunction with the fixed blades to pulverize materials such as tea leaves.

[0004] However, most hand-cranked grinders on the market currently have a significant drawback. Existing models typically only have one fixed blade and one rotating blade, forming a single-layer structure. When grinding tea leaves, the lack of cross-mixing from multiple blades makes it difficult for the tea leaves to be fully turned and cut within the limited space, resulting in insufficient mixing and a significantly reduced grinding effect. This severely impacts the taste and flavor of subsequent brews, thus requiring improvement. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model proposes a tea crusher with a simple structure that can cut tea leaves into smaller and more complete pieces, resulting in a better taste after brewing.

[0006] The technical solution of this utility model is implemented as follows:

[0007] A tea crusher includes: a body comprising a first storage box, a second storage box, and a crushing zone located between the two storage boxes; the first and second storage boxes are detachably connected to the crushing zone via a locking structure; the crushing zone includes two longitudinally distributed crushing sections and a main drive gear located between the two crushing sections; each crushing section includes several rows of fixed blades and a rotating shaft perpendicular to the fixed blades; one end of the rotating shaft is provided with a driven gear; multiple rotating blades are provided on the rotating shaft; the rotating blades and the fixed blades are interleaved; the main drive gear meshes with two upper and lower driven gears; and a power input mechanism is also included, which causes the main drive gear to rotate.

[0008] In a preferred embodiment, the power input mechanism is a handle, which is located on the body of the machine body. A stabilizing shaft is provided between the two crushing sections. The stabilizing shaft passes through both ends of the machine body and exits through the main drive gear, and is rotatably connected to the handle.

[0009] In a preferred embodiment, the power input mechanism is a drive mechanism, a main control board is provided inside the machine body, and function buttons are correspondingly provided outside the machine body. The drive mechanism and function buttons are electrically connected to the main control board; the drive mechanism is driven by the main transmission gear.

[0010] In a preferred embodiment, the plurality of rotating blades are staggered at different angles along the rotation axis.

[0011] In a preferred embodiment, both the first and second storage boxes are provided with a feeding inclined channel at the connection between them and the crushing zone.

[0012] In a preferred embodiment, the distance between the rotating blade and its left and right adjacent fixed blades is 1 mm.

[0013] In a preferred embodiment, the longitudinal section of the outer end of each row of rotating blades is Y-shaped.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This invention provides a tea shredder that enables more thorough tea shredding. The shredder consists of two storage boxes, one above the other, and a shredding zone in the middle. The storage boxes and the shredding zone are detachably connected by a snap-fit ​​structure. Before shredding, the user can place the tea leaves in one of the storage boxes, with the empty box facing down; the shredded tea leaves will then fall into the lower storage box.

[0016] The grinding zone has two grinding sections arranged longitudinally, with a main drive gear installed between them. Each grinding section contains several rows of fixed blades and a rotating shaft perpendicular to the fixed blades. One end of the rotating shaft has a driven gear, and several rows of rotating blades are mounted on the shaft, with the rotating blades interlacing with the fixed blades. During operation, the main drive gear meshes with the driven gears in the upper and lower layers. When an external force drives the main drive gear to rotate, it drives the driven gears in the upper and lower layers to rotate synchronously, thereby causing the rotating shaft and rotating blades to rotate. The cut tea leaves fall through the gaps between the fixed and rotating blades, and after being cut by the two grinding sections, they fall into the storage box below. Compared to the traditional single-layer grinding section design, this invention features two grinding sections, which allows for more thorough cutting, resulting in finer and more uniform tea particles, greatly improving the quality and taste of the broken tea, and fully meeting users' needs for high-quality broken tea.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first," "second," "third," and "fourth," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] See Figures 1 to 5 This utility model discloses a tea crusher, comprising a body 100, a first storage box 10, a second storage box 11, and a crushing zone 20 located between the two storage boxes. The first storage box 10 and the second storage box 11 are detachably connected to the crushing zone 20 via a snap-fit ​​structure. Further, the crushing zone 20 includes two longitudinally distributed crushing sections 30 and a main drive gear 40 located between the two crushing sections 30. Each crushing section 30 includes several rows of fixed blades 31 and a rotating shaft 32 perpendicular to the fixed blades 31. One end of the rotating shaft 32 is provided with a driven gear 33, and multiple rotating blades 34 are provided on the rotating shaft 32. The rotating blades 34 and the fixed blades 31 are interleaved. The main drive gear 40 is meshed with the upper and lower driven gears 33. The machine also includes a power input mechanism that causes the main drive gear 40 to rotate.

[0036] Specifically, the upper and lower first storage boxes 10 and the second storage box 11 of the machine body 100 are both used to hold tea leaves. In use, the tea leaves to be crushed can be placed in one of the storage boxes (such as the first storage box 10), with the first storage box 10 containing the tea leaves on top and the second storage box 11 on the bottom. When the tea crusher starts working, the power input mechanism (external force) acts on the main drive gear 40 to make it rotate. Since the main drive gear 40 is meshed with the driven gears 33 of the upper and lower crushing sections 30, the rotation of the main drive gear 40 will drive the two driven gears 33 to rotate synchronously. The driven gears 33 are installed at one end of the rotating shaft 32, so the rotation of the driven gears 33 can drive the rotating shaft 32 to rotate around its own axis. Multiple rotating blades 34 are installed on the rotating shaft 32, and the rotating blades 34 of the two crushing sections 30 will begin to rotate as the rotating shaft 32 rotates. These rotating blades 34 and the fixed blades 31 are interleaved, and during rotation, a cutting area is formed between the rotating blades 34 and the fixed blades 31. Once the tea leaves enter the crushing zone 20 from the first storage box 10, they are repeatedly cut and crushed by the rotating blade 34 and the fixed blade 31 within this cutting area, gradually breaking the tea leaves into smaller particles. When the tea particles are small enough, they will fall through the gap between the rotating blade 34 and the fixed blade 31 into the second storage box 11, until all of them have fallen out. If the tea leaves still need further cutting, the machine body 100 can be inverted, with the second storage box 11 on top and the first storage box 10 on the bottom, and the above cutting steps can be repeated.

[0037] In existing technologies, such pulverizers typically contain only one pulverizing section, making it difficult to cut the tea leaves thoroughly, leaving large particles in the tea. In contrast, this invention features two pulverizing sections 30, which, driven by the main drive gear 40, achieve thorough cutting of the tea leaves. After processing by the two pulverizing sections, the pulverized tea particles are finer and more uniform, allowing the tea to release its aroma more fully during subsequent brewing, thus improving its quality. Furthermore, this tea pulverizer is equipped with two storage boxes. After the first round of pulverization, if further cutting is needed, simply invert the machine body 100 and perform the cutting operation again, which is quite convenient.

[0038] like Figure 3 and Figure 4 Each row of fixed blades 31 is connected to the upper and lower sides of the crushing zone 20, forming a relatively fixed cutting structure; several rotating blades 34 are mounted on the rotating shaft 32. The length of the rotating blades 34 is slightly shorter than the length of the fixed blades 31, so that the rotating blades 34 will not touch the upper and lower sides of the crushing zone 20 when rotating. The rotating blades 34 rotate with the rotating shaft 32; specifically, as Figure 5The rotating blades 34 are not arranged neatly in one direction, but are staggered at different angles on the rotating shaft 32. When rotating, they can cover a larger area, allowing more tea leaves to come into contact with the blades, increasing the cutting range and enhancing the crushing effect.

[0039] In this embodiment, the aforementioned power input mechanism is a handle 50, which is located on the body of the machine body 100. The user rotates the handle 50 to rotate the main drive gear 40. A stabilizing shaft 60 is provided between the two crushing parts 30. The stabilizing shaft 60 passes through both ends of the machine body 100 and exits through the main drive gear 40, rotatably connecting with the handle 50. The handle 50 facilitates the user's application of force, and the stabilizing shaft 60 passes through the machine body, making the connection between the handle 50 and the main drive gear 40 more stable, ensuring that force is stably transmitted from the handle 50 to the main drive gear 40.

[0040] In addition to the aforementioned method of using the handle 50 to drive the main drive gear 40 to rotate the two crushing sections 30, this embodiment also provides another solution. Specifically, the aforementioned power input mechanism is a drive mechanism (not shown in the figure), a main control board (not shown in the figure) is provided inside the machine body 100, and corresponding function buttons (not shown in the figure) are provided outside the machine body 100. Both the drive mechanism and the function buttons are electrically connected to the main control board, and the drive mechanism is driven by the main drive gear 40. By operating the function buttons, the user can adjust the cutting time, and the main control board will control the drive mechanism to drive the main drive gear 40 to rotate, eliminating the need for manual operation and making it more convenient and efficient.

[0041] like Figure 2 and Figure 3 In this embodiment, both the first storage box 10 and the second storage box 11 are provided with a feeding inclined channel 70 at the connection with the crushing zone 20. When the tea crusher is working, as the rotating blade 34 rotates, some tea leaves may be knocked out of the upper crushing zone 20 and make it difficult for them to fall into the crushing zone 20 for continuous crushing. The feeding inclined channel 70 can ensure that the tea leaves can slide back into the crushing zone 20 smoothly, thereby improving the crushing efficiency.

[0042] Preferably, the distance between the rotating blade 34 and its adjacent fixed blades 31 is 1mm. If the tea leaves are cut small enough, they can fall into the storage box below through this distance. This distance is controlled to cut finer tea leaves and meet the demand for high-quality tea leaves.

[0043] In this embodiment, the longitudinal section of the outer end of the rotating blade 34 is Y-shaped, which makes the area covered by the blade larger when rotating, and can contact more tea leaves, reducing the blind spot of crushing and making the tea leaves fully cut.

[0044] like Figure 1When this tea crusher is in operation, the user first puts tea leaves into one of the storage boxes (taking the first storage box 10 as an example). Then, the user closes the tea crusher so that the first storage box 10 is on top and the second storage box 11 is on the bottom. Next, the user turns the handle 50, which rotates the main drive gear 40, thereby rotating the two driven gears 33. This causes the rotating shaft 32 to rotate, and the fixed blade 31 and rotating blade 34 cut the tea leaves into small tea particles. After being cut by the two crushing sections 30, the tea leaves fall from the upper first storage box 10 into the lower second storage box 11. The tea leaves are crushed to a certain size, falling only between adjacent fixed and rotating blades, ensuring that the final collected tea particles are small and uniform. This tea crusher can be used in homes or milk tea shops, etc. Small tea particles release flavor more easily, releasing the aroma and taste of tea more quickly during brewing, making the tea more concentrated and significantly improving the quality of the tea.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
