Description

Technical Field

[0001] This utility model belongs to the technical field of tea processing and stir-frying, specifically relating to an auxiliary device for stir-frying tea. Background Technology

[0002] Stir-frying tea leaves is a crucial step in tea processing, directly affecting the aroma, taste, and quality of the tea. In the processing of green tea, oolong tea, and other tea types, stir-frying is mainly used in the fixation and rolling processes. Fixation uses high temperatures to quickly deactivate enzymes in the tea leaves, preventing excessive oxidation, removing grassy taste, and enhancing the aroma. Rolling, on the other hand, involves repeated stirring to break down tea cell walls, promoting the release of tea juices, and further shaping the tea's form and flavor. Traditional hand-stirring relies on experienced tea masters who use a spatula to continuously turn the tea leaves in the wok to ensure even heating and prevent scorching or uneven fermentation.

[0003] When stir-frying tea leaves using traditional spatulas, the main method relies on the movement of the manual arm, making it difficult to precisely cover every corner of the wok. Especially when working with a large wok, the tea leaves at the edges and in the center are stir-fried to varying degrees, resulting in some leaves not being fully heated and retaining moisture, while others are burnt. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for stirring tea leaves during processing, addressing the problem in the background art where traditional stir-frying relies mainly on manual arm movements, making it difficult to accurately cover every corner of the wok. Especially in large-area wok operations, the degree of stirring varies greatly between the edges and the center, easily resulting in some tea leaves not being fully heated and retaining moisture, while others become burnt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stir-frying auxiliary device for tea processing, comprising a connecting rod and a dome disposed on the lower side of the connecting rod for supporting rotation;

[0006] The upper end of the connecting rod is provided with an inner sleeve, the inner sleeve has an inner cavity, the upper outer side of the inner sleeve is provided with a handle, the inner side of the handle is provided with an inner drive cavity, a spring is provided between the inner drive cavity and the inner side of the inner sleeve, and a drive thread is provided at the connection between the handle and the inner sleeve.

[0007] The dome has slots at five equal angles on its outer side, and the movable block is located inside the slots. An outer sleeve block is located on the right side of the movable block. A rotating ring is connected inside the right side of the outer sleeve block. A rotating rod is connected to the right side of the rotating ring. A sweeping ring is located on the right side of the rotating rod.

[0008] Preferably, a retaining ring is provided at the connection between the rotating rod and the inner side of the rotating ring, and the sweeping ring is connected to the rotating rod by welding.

[0009] Preferably, the rotating rod is connected to the rotating ring by a retaining ring, and the rotating rod can drive the sweeping ring to rotate inside the rotating ring using the retaining ring.

[0010] Preferably, a rotating shaft is provided at the middle left side of the rotating ring and the outer sleeve block, and the rotating ring can rotate up and down inside the outer sleeve block via the rotating shaft.

[0011] Preferably, the movable block is connected to the slotted block by a movable connection method and to the outer casing block by welding, and the movable block can rotate up and down within the slot.

[0012] Preferably, the grip is connected to the inner sleeve via a drive thread, and the grip can rotate and move up and down outside the inner sleeve via the drive thread. The upper and lower ends of the spring are respectively connected to the top of the inner side of the grip and the bottom of the lower side of the inner sleeve via bolts.

[0013] Compared with the prior art, this utility model provides a stir-frying auxiliary device for tea processing, which has the following beneficial effects:

[0014] 1. The unique structure and connection method of the sweeping ring enable it to perform irregular sweeping movements at the bottom of the wok. This complex motion trajectory covers all areas of the wok bottom, preventing uneven heating of the tea leaves. Whether the tea leaves are at the edge or in the center of the wok, they can be thoroughly stir-fried, ensuring that each tea leaf receives consistent heating and stirring during processing, significantly improving the uniformity of tea stir-frying.

[0015] 2. Users can easily drive the entire device to rotate and stir-fry simply by pressing the handle. The operation is simple and continuous, greatly reducing labor intensity compared to traditional manual stirring methods. Continuous pressing of the handle enables uninterrupted stirring, shortening the time required for tea processing, improving work efficiency, and helping to complete more tea processing tasks within a unit of time.

[0016] Furthermore, even stirring ensures that the tea leaves are heated uniformly, effectively removing moisture and reducing the risk of scorching or uneven drying due to uneven heating. This helps maintain the tea's color, aroma, and taste, resulting in tea that is superior in both appearance and internal quality, thus increasing its commercial value.

[0017] 3. The device's operating principle is based on common threaded transmission and spring return, with a simple and easy-to-understand structural design. Users can operate it without complex training, lowering the barrier to entry. Furthermore, the pressing operation of the handle can be flexibly controlled according to actual needs. For example, the frequency and force of pressing can be adjusted based on the amount of tea leaves, the type of tea leaves, and the required stirring intensity to achieve the best stirring effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0026] This utility model provides, for example Figure 1-6 The stir-frying auxiliary device for tea processing shown includes a connecting rod 2 and a dome 4 disposed on the lower side of the connecting rod 2 for supporting rotation;

[0027] The upper end of the connecting rod 2 is provided with an inner sleeve 3, the inner sleeve 3 has an inner cavity 8, the upper outer side of the inner sleeve 3 is provided with a handle 1, the inner side of the handle 1 is provided with an inner drive cavity 7, the inner drive cavity 7 and the inner side of the inner sleeve 3 are provided with a spring 6, and the connection between the handle 1 and the inner sleeve 3 is provided with a drive thread 9.

[0028] The outer side of the dome 4 has five slots at equal angles, and a movable block 14 is provided on the inner side of the slots. An outer sleeve block 12 is provided on the right side of the movable block 14. A rotating ring 11 is connected to the inner right side of the outer sleeve block 12. A rotating rod 10 is connected to the right side of the rotating ring 11. A sweeping ring 5 is provided on the right side of the rotating rod 10.

[0029] Optionally, the sweeping ring 5 is composed of cross-shaped elliptical rings.

[0030] In this embodiment, when the device is not in use, the handle 1 is located at the top of the inner sleeve 3, and the spring 6 is in a naturally extended state. The sweeping ring 5 is connected to the dome 4 through the rotating rod 10, the rotating ring 11, the outer sleeve block 12, and the movable block 14, and the sweeping ring 5 is in the initial stationary position, with the arc-shaped outer wall of the dome 4 gently contacting the bottom center of the wok.

[0031] The user holds the handle 1 and presses it down. Since the handle 1 and the inner sleeve 3 are connected by the drive thread 9, during the downward pressing process, the handle 1 will move downward while driving the inner sleeve 3 and the connecting rod 2 connected to it to rotate around its own axis due to the action of the thread.

[0032] The dome 4 on the lower side of the connecting rod 2 rotates accordingly, and the structure consisting of the movable block 14, the outer sleeve block 12, the rotating ring 11, and the rotating rod 10, which are distributed at equal angles on the outer side of the dome 4, also rotates accordingly. Because the rotating rod 10 and the rotating ring 11 are connected by a retaining ring 15, the rotating rod 10 can drive the sweeping ring 5 to rotate inside the rotating ring 11; the rotating ring 11 is connected to the outer sleeve block 12 through the rotating shaft 13 and can rotate up and down inside the outer sleeve block 12; the movable block 14 is movably connected to the slot and can rotate up and down within the slot. Therefore, during the rotation of the dome 4, the sweeping ring 5 will rotate with the dome 4 as a whole, and on the other hand, due to the mobility of each connecting structure, it will make irregular sweeping movements at the bottom of the wok, stirring the tea leaves.

[0033] By continuously pressing the handle 1, the aforementioned rotation and sweeping actions are repeated to continuously stir-fry the tea leaves. When the user releases the handle 1, the spring 6 will rebound upwards due to its elasticity, pushing the handle 1 back to its initial position. At the same time, it will cause the connecting rod 2 to reverse, returning the sweeping ring 5 and other structures to their respective initial positions, completing one operation cycle. By repeatedly operating the handle 1 in this way, the sweeping ring 5 can be used to continuously assist in stirring the tea leaves in the wok.

[0034] like Figure 1-6 As shown, a retaining ring 15 is provided at the inner connection of the rotating rod 10 and the rotating ring 11. The sweeping ring 5 is connected to the rotating rod 10 by welding. The rotating rod 10 is connected to the rotating ring 11 by the retaining ring 15. The rotating rod 10 can drive the sweeping ring 5 to rotate inside the rotating ring 11 using the retaining ring 15. A rotating shaft 13 is provided at the middle left side of the rotating ring 11 and the outer sleeve block 12. The rotating ring 11 can rotate up and down inside the outer sleeve block 12 through the rotating shaft 13. The movable block 14 is connected to the slot by a movable connection and to the outer sleeve block 12 by welding. The movable block 14 can rotate up and down in the slot. The handle 1 is connected to the inner sleeve 3 by the driving thread 9. The handle 1 can rotate up and down outside the inner sleeve 3 by the driving thread 9. The upper and lower ends of the spring 6 are connected to the top inner side of the handle 1 and the bottom lower side of the inner sleeve 3 by bolts, respectively.

[0035] Preferably, the dome is spherical in shape, and the outer wall of the dome contacts the bottom center of the outer tea-stirring wok.

[0036] Preferably, the device utilizes the threaded connection between the handle 1 and the inner sleeve 3 to convert the linear motion of the user pressing down on the handle 1 into the rotation of the inner sleeve 3 and the connecting rod 2, providing the main rotational power source for the entire device. Simultaneously, the spring 6 acts as a reset mechanism, allowing the handle 1 to automatically return to its initial position after each press, facilitating the user's next pressing operation and forming a continuous and stable power input.

[0037] Dome 4 serves as a rotational support point, and its rotation drives a series of connected structural movements. The sweeping ring 5 is connected to dome 4 via rotating rod 10, rotating ring 11, outer sleeve block 12, and movable block 14, and each connecting part has a certain degree of mobility. This allows the sweeping ring 5 to rotate and swing up and down on its own while rotating with dome 4 as a whole, thus forming a complex sweeping trajectory at the bottom of the wok. This allows for all-round and multi-angle stirring of the tea leaves, improving the stirring effect, ensuring even heating of the tea leaves, and effectively removing moisture.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
