Detailed Implementation

[0016] To make the technical problems and solutions solved by this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0017] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," and "connect" 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. Example 1

[0019] like Figure 1 , Figure 5 As shown, a convenient and intelligent tea-prying knife for Anhua dark tea has an overall T-shaped structure, including a handle 1, a support rod 2, a threaded tea knife 3 connected from top to bottom, a spring post 4 sleeved on the outside of the threaded tea knife 3, and a motor drive system built into the support rod 2. They are arranged along the same axis to achieve "one-click screwing in and safe tea prying".

[0020] Handle 1 is cylindrical and can be made of metal or other environmentally friendly materials. It is ergonomic and easy to grip and operate. Figure 5 Figure 6 As shown, the center of the handle 1 is provided with a T-shaped through groove 101 for the first screw 204 to pass through and be fixed. When it cooperates with the first nut 205, it can realize the quick-release connection between the support rod 2 and the handle 1, while hiding the threads to avoid cutting hands.

[0021] like Figure 3-6 As shown, support rod 2 is an openable hollow structure, composed of two hollow semi-circular shells joined together. Its interior and bottom are hollow, used to house the motor drive system and connect the threaded tea knife 3. The joining structure of the two semi-circular shells is as follows: one side of the two semi-circular shells is hinged by an internal hinge 201, and the other side is engaged by corresponding locking blocks 202 and locking slots 203 respectively provided on the two semi-circular shells. This allows for tool-free opening and closing, facilitating the replacement of the motor drive system. It should be noted that the number of internal hinges 201, locking blocks 202, and locking slots 203 can be reasonably configured according to the length of the two semi-circular shells, and the specific installation position can be any position as long as it does not obstruct the motor drive system.

[0022] The top of the support rod 2 is equipped with a first screw 204 and a first nut 205. After the first screw 204 passes through the T-shaped through hole 101, the first nut 205 is screwed on to connect and fix it to the handle 1, while simultaneously pressing and fixing the two semi-circular shells. The outer surface of the bottom end of the support rod 2 is provided with an external thread 206 and a matching second nut 207, and the center of the second nut 207 has a through hole 208 for the threaded tea knife 3 to pass through. After the motor drive system is built into the inner cavity of the support rod 2, screwing on the second nut 207 can seal the motor drive system in the inner cavity to prevent it from slipping out, while simultaneously pressing the two semi-circular shells again. The threaded tea knife 3 can then pass through the through hole 208 and connect to the motor drive system.

[0023] The side wall of the support rod 2 integrates control switches corresponding to the motor drive system, specifically including a power switch 601, a motor switch 602, and a speed control switch 603. The motor switch 602 controls the forward and reverse rotation of the motor, while the speed control switch 603 controls the motor's operating speed. Furthermore, the top side wall of the support rod 2 is equipped with a charging port 604 with a rubber flip cover, and a dedicated charger is included for USB charging.

[0024] like Figure 6 As shown, the threaded tea knife 3 is designed to be interchangeable in various specifications, consisting of an upper screw 301 and a lower blade 302. The screw 301 is designed to a uniform specification, threaded to the internal thread of the drive shaft 504. The blade 302 is designed as a conical shape with external threads (for tightly compressed tea), or a flat, unthreaded shovel or cross-shaped blade (for loose tea), with a finely ground tip at its lowest point to reduce penetration resistance. Furthermore, when the blade 302 is a conical shape with external threads, its outer surface also has a vertical groove 303. When the threaded tea knife 3 rotates, the vertical groove 303 can immediately remove tea chips and dissipate heat, preventing tea chips from clogging the tea and burning the tea leaves at high temperatures. Of course, blades 302 of different lengths, blade types, and screw pitches all retain the same screw 301, allowing users to quickly change blades according to the hardness and size of the tea brick (cake, cylinder).

[0025] like Figure 1 As shown, the spring post 4 is sleeved on the outer periphery of the threaded tea knife 3, forming an elastic safety sleeve for the blade tip 302. The upper end of the spring post 4 is connected to the outer edge of the second nut 207 and is fixed integrally with the nut; the lower end is connected to a hollow positioning ring 401, which contacts the tea surface before the blade tip 302, providing stable support and inhibiting side slippage; the middle is a high-elasticity stainless steel spring, whose length is slightly longer than the blade tip 302, ensuring that the entire blade tip 302 is wrapped and fingers cannot touch the blade edge; it compresses smoothly under force, without pinching or jamming.

[0026] like Figure 5-7As shown, the motor drive system is located inside the support rod 2 and includes a battery 501, a motor 502, a reduction gear 503, a drive shaft 504, and bearings 505. The battery 501 is a rechargeable lithium battery and is electrically connected to the motor 502. The output shaft of the motor 502 is connected to the reduction gear 503, and the output shaft of the reduction gear 503 is connected to the drive shaft 504. Two bearings 505 are spaced apart between the outer circumference of the drive shaft 504 and the inner wall of the support rod 2, and are embedded in the inner wall of the support rod 2 to ensure stable rotation of the drive shaft 504 inside the support rod 2, reducing vibration and uneven wear. The free end of the drive shaft 504 has an internal thread for connection with the screw 301. When the motor 502 is working, the torque is amplified by the reduction gear 503, driving the drive shaft 504 to rotate, thereby causing the threaded tea knife 3 to rotate at low speed and high torque. The user only needs to lightly press the handle 1, and the knife head 302 will automatically screw into the tea, completing the tea-picking process.

[0027] It should be noted that the circuit connections between the motor drive system and the control switch, and between the charging port 604 and the battery are existing technologies and will not be elaborated on here.

[0028] Working principle: Based on the tightness and size of the tea brick (cake, pillar), select the corresponding specification of threaded tea knife 3 and spring post 4. Screw the screw 301 of the threaded tea knife 3 into the drive shaft 504. Then, put the spring post 4 and the second nut 207 connected to the upper part onto the outer circumference of the knife head 302. Then, screw the second nut 207 onto the external thread 206 at the bottom of the support rod 2 to complete the assembly of the utensils.

[0029] Holding handle 1 with one hand, place the hollow positioning ring 401 onto the target position on the tea. Turn on the power switch 601 and motor switch 602 (default forward rotation). The motor 502, via the reduction gear 503, reduces its speed and increases its torque. The drive shaft 504 rotates smoothly under the support of two bearings 505, driving the blade 302 to slowly and powerfully insert into the tea. The user only needs to apply a small axial force to complete the insertion and loosening. During this process, the vertical grooves 303 on the surface of the blade 302 continuously discharge tea debris and carry away frictional heat, preventing clogging and scorching.

[0030] When the desired depth is reached or a sudden drop in torque is felt (the tea has loosened), release motor switch 602, and motor 502 will immediately lose power. Gently press the reverse switch on motor 502, and the blade will rotate out in the opposite direction; spring post 4 will simultaneously and elastically return to its original position, continuing to cover the blade edge to prevent cuts during retraction. Repeat this process multiple times to loosen the tea.

[0031] When the motor drive system needs to be cleaned or replaced, simply unscrew the threaded tea knife 3, the first nut 205 and the second nut 207 by hand, and pry open the retaining block 202 and the retaining groove 203 to open the support rod. Tool-free maintenance is required.

[0032] This embodiment realizes a complete closed loop of "one-click automatic screw-in - safe knife retraction - quick manual disassembly and maintenance", which greatly reduces the threshold for prying tea, allowing users to easily pry open any tightly compressed Anhua black tea, without hurting their hands, breaking the tea, or burning it. Example 2

[0033] like Figure 8 As shown, this embodiment is based on embodiment 1, and embeds an intelligent recognition module inside the threaded tea knife 3 to achieve a digital appraisal experience of prying and inspecting simultaneously. The intelligent recognition module includes a micro battery 701, a micro motherboard 702, a micro sensor 703, and a micro infrared camera 704. The micro battery 701 and micro motherboard 702 are inserted into a pre-reserved compartment at the upper end of the knife head 302, coaxially balanced with the knife head 302, and do not affect rotation. The micro sensor 703 and micro infrared camera 704 are sequentially embedded at the lower end of the knife head 302. A wire hole 705 is provided at the central axis of the knife head 302 to facilitate concealed wiring between the micro components and prevent breakage during rotation. The miniature battery 701 is electrically connected to three other miniature components to provide power. The miniature sensor 703 and the miniature infrared camera 704 are signal-connected to the miniature motherboard 702. The miniature sensor 703 is used to read the tea color, golden flower density, and moisture content in real time, while the miniature infrared camera 704 captures images of the tea's cross-section in real time and transmits this data to the miniature motherboard 702. Additionally, the miniature motherboard 702 can wirelessly connect to a computer or mobile terminal to transmit tea data to the terminal device for storage and display, facilitating user tasting.

[0034] It should be noted that the micro-components included in the intelligent identification module are all existing products. Specific components with corresponding functions can be configured according to the evaluation needs to meet the data collection requirements. Furthermore, the circuit connections between the various micro-components are existing technology and will not be elaborated upon here.

[0035] Working Principle: As the blade 302 screws into the drive shaft 504, the micro battery 701 automatically closes via a magnetic switch (or plug-in contact point), energizing the intelligent identification module. At the moment the blade 302 pierces the tea, the miniature infrared camera 704 continuously captures images of the cross-section, with infrared illumination ensuring clear images even in low-light conditions. The miniature sensor 703 simultaneously collects data on tea color, golden flower density, and local moisture content, promptly feeding this data back to the micro motherboard 702, which then transmits it to the terminal device for storage and display, facilitating user tasting. Once the blade 302 has completely withdrawn from the tea, the micro motherboard 702 determines that the tea-picking process is complete and automatically shuts down the detection components.

[0036] This embodiment achieves an immersive digital tasting experience of "prying and testing the tea simultaneously" without adding any extra steps, giving traditional Anhua dark tea a visual and data-driven tea-opening experience.

[0037] The present invention has been described in detail above through specific and preferred embodiments. However, those skilled in the art should understand that the present invention is not limited to the embodiments described above. Any modifications or equivalent substitutions made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
