Description

Technical Field

[0001] This utility model relates to the field of tea fermentation technology, and in particular to a hot air control device for tea fermentation. Background Technology

[0002] Tea fermentation refers to the sum of a series of enzymatic and non-enzymatic oxidation reactions that occur within tea leaves under specific temperature, humidity, and oxygen conditions. These reactions lead to changes in the color, aroma, and taste of the tea. Depending on the degree of fermentation, tea can be classified into different types such as non-fermented (e.g., green tea), semi-fermented (e.g., oolong tea), and fully fermented (e.g., black tea).

[0003] Currently, hot air equipment is needed to output hot air during tea fermentation to maintain a certain temperature in the fermentation chamber to meet the actual fermentation conditions. Therefore, hot air blowers are commonly used. Hot air blowers draw in outside air, heat it through internal heating wires, and then output it into the fermentation chamber for heating. However, in practical applications, it has been found that a lot of dust particles accumulate on the air intake grille on the lower surface of the air inlet after long-term use. Therefore, regular cleaning is required, otherwise it will affect the heating output air volume and the operating performance of the hot air blower. However, cleaning requires stopping the operation of the hot air blower, which will affect the application of hot air fermentation. To address this, a hot air control device for tea fermentation is proposed. Utility Model Content

[0004] Therefore, it is necessary to provide a hot air control device for tea fermentation that addresses the aforementioned technical problems. This device employs a double-layer filter design, allowing the individual filter to be removed and the other layer to operate when needed. This enables simultaneous cleaning of the filter without affecting the hot air fermentation process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A hot air control device for tea fermentation includes a hot air body, on the surface of which a hot air output end and an air input end are distributed. A guide protrusion is provided on the surface of the hot air body near the air input end, and a filter mechanism is provided on the surface of the guide protrusion. The filtration mechanism includes a sealing ring body, with limit rings fixed at both ends of the inner side of the sealing ring body, and a filtration space is formed between the two limit rings, with a sealing disc provided in the filtration space; The sealing disc has a fan-shaped ventilation groove on its surface, and a fan-shaped filter screen is attached to the surface of the sealing disc. A connecting piece is fixed between multiple fan-shaped filters, and rotating the fan-shaped filter screen can move it to a position opposite to the fan-shaped ventilation groove.

[0006] Furthermore, the filter mechanism has two components, which are fitted together.

[0007] Furthermore, a threaded connection boss is formed on one side of the sealing ring body, and a threaded connection groove is formed on the other side of the sealing ring body to match the threaded connection boss. The two filter mechanisms can be fitted together by the action of the threaded connection boss and the threaded connection groove.

[0008] Furthermore, connecting seats are fixed on both sides of the surface of the sealing ring, and the interior of the connecting seat has a movable cavity, in which a locking plate is provided that is movably connected to the side wall of the connecting seat.

[0009] Furthermore, rubber abutment protrusions are fixedly connected to both sides of the locking plate.

[0010] Furthermore, the hot air output end of the hot air unit is also fixedly connected to a trapezoidal diverter, which is connected to the external tea fermentation box.

[0011] Furthermore, a connecting frame is also fixed to the surface of the hot air unit.

[0012] Furthermore, the outer end of the guide boss is formed with a threaded connection end that is adapted to the threaded connection groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects: The hot air control device for tea fermentation provided by this utility model adopts a double-layer fan-shaped filter screen. When a large amount of dust particles are attached to a single fan-shaped filter screen during actual fermentation hot air and cleaning is required, the screen can be removed independently, and the other fan-shaped filter screen can be unfolded to work. This allows the fan-shaped filter screen to be cleaned simultaneously while hot air fermentation is underway, making it more practical. By setting the threaded connection boss and threaded connection groove, rotating the sealing ring body to form a threaded engagement with the adjacent threaded connection groove can achieve quick disassembly or assembly of a single sealing ring body. At the same time, flipping the locking plate and placing it into the adjacent connecting seat can further improve the stability of the connection between the two sealing ring bodies. At the same time, adjusting the sealing discs in the two sealing rings to an interlaced state can effectively block the air input end, thus providing better protection for the inside of the hot air unit. In addition, the trapezoidal diversion hood design can control and divert the output hot air in multiple directions, making it flow more evenly in the fermentation chamber.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0017] Example 1 Please refer to Figures 1-5 As shown, a hot air control device for tea fermentation includes a hot air body 1. The surface of the hot air body 1 is distributed with a hot air output end 11 and an air input end 12. A guide protrusion 13 is provided on the surface of the hot air body 1 near the air input end 12. A filter mechanism 2 is provided on the surface of the guide protrusion 13. The filter mechanism 2 includes a sealing ring body 21, with limiting rings 22 fixed at both ends of the inner side of the sealing ring body 21, and a filter space 23 is formed between the two limiting rings 22. A sealing disc 24 is provided in the filter space 23. The sealing disk 24 has a fan-shaped ventilation groove 25 on its surface, and a fan-shaped filter 26 is attached to the surface of the sealing disk 24. A connecting piece 27 is fixed between multiple fan-shaped filters 26. Rotating the fan-shaped filter 26 can move it to a position opposite to the fan-shaped ventilation groove 25. In practical applications, after the hot air unit 1 is installed in a suitable position and started, it can input external air into the interior of the hot air unit 1 through the air inlet 12. Then, after being heated by the heating wire inside (a conventional known component inside the hot air unit, which does not need to be further explained in this embodiment), the air is finally discharged to the outside through the hot air outlet 11. In this way, the hot air can be effectively output into the tea fermentation chamber for heating, thereby realizing the hot air control of tea fermentation. During the heating process described above, the externally input space can be filtered by the filter mechanism 2, thereby ensuring the stable operation of the hot air unit 1. In practical applications, when the surface of the fan-shaped filter 26 inside a single sealing ring 21 is covered with a lot of dust, it can be disassembled independently, allowing another fan-shaped filter 26 to unfold. This achieves the cleaning effect of the fan-shaped filter 26 without affecting the hot air fermentation.

[0018] Example 2 The hot air control equipment for tea fermentation provided in Example 1 has been further optimized, specifically, as follows: Figure 4 As shown, there are two filter mechanisms 2, which are fitted together. A threaded connection boss 210 is formed on one side of the sealing ring body 21, and a threaded connection groove 211 adapted to the threaded connection boss 210 is formed on the other side of the sealing ring body 21. The two filter mechanisms 2 can be fitted together by the action of the threaded connection boss 210 and the threaded connection groove 211. The outer end of the flow guide boss 13 is formed with a threaded connection end 130 that is adapted to the threaded connection groove 211; like Figure 1 As shown, the two sealing rings 21 are fitted together in sequence, and the connection between them is maintained by the threaded connection boss 210 and the threaded connection groove 211. Meanwhile, the sealing ring 21 close to the guide boss 13 is rotated and fastened to the threaded connection end 130 through the threaded connection groove 211 on it. In this way, the filter mechanism 2 can be assembled on the hot air body 1. In practical application, the fan-shaped filter 26 inside the outermost sealing ring 21 rotates to a position opposite to the fan-shaped ventilation slot 25. At this time, when the external air is input into the hot air unit 1 through the fan-shaped ventilation slot 25, it will be filtered by the fan-shaped filter 26 (it should be noted that the air filtration in this embodiment is relative and does not completely achieve the filtration effect; it is just an optimization for conventional hot air units without a filter structure). The fan-shaped filter 26 inside the inner sealing ring 21 is located on the back of the corresponding sealing disc 24. Therefore, the fan-shaped ventilation slot 25 inside is unobstructed, and the two fan-shaped ventilation slots 25 are in a corresponding state after the two sealing rings 21 are assembled. When the outer fan-shaped filter 26 needs to be cleaned, rotate the outer sealing ring 21 to remove it, and then rotate the fan-shaped filter 26 inside the other sealing ring 21 so that it forms an interlaced state with the fan-shaped ventilation groove 25. In this way, the normal hot air fermentation and filtration of the hot air unit 1 can be maintained without affecting the cleaning of the fan-shaped filter 26 after removal.

[0019] Example 3 The hot air control equipment for tea fermentation provided in Embodiment 1 or 2 can be further optimized, such as... Figure 1-3 As shown, connecting seats 212 are fixed on both sides of the surface of the sealing ring 21. The connecting seat 212 has a movable cavity 213 inside. A locking plate 214 that is movably connected to the side wall of the connecting seat 212 is provided in the movable cavity 213 on one of the sealing rings 21. Both sides of the locking plate 214 are fixedly connected with rubber abutment protrusions 215; like Figure 3 As shown, the locking plate 214 is located on the sealing ring 21 near the guide boss 13. When both sealing rings 21 are assembled, the connecting seats 212 are in a one-to-one correspondence. By flipping the locking plate 214, it can be placed inside the adjacent connecting seat 212, so that the rubber abutment convex button 215 is compressed and squeezed against the side wall of the corresponding connecting seat 212. This can limit the two sealing rings 21 and prevent them from falling off on their own without external force.

[0020] Example 4 The hot air control equipment for tea fermentation provided in Example 3 has been further optimized, such as... Figure 1 The hot air output end 11 of the hot air body 1 shown is also fixedly connected to a trapezoidal diverter 110, which is connected to an external tea fermentation box. The surface of the hot air unit 1 is also fixed with a connecting frame 14, which can be used to fix the hot air unit 1 to an external support to ensure stable connection during hot air output. Since the output diameter of the hot air output end 11 of the hot air unit 1 is limited, a trapezoidal flow divider 110 is set on it. In this way, when the hot air is output, the hot air can be dispersed by controlling the trapezoidal flow divider 110, so that the hot air can flow better in the fermentation chamber and help to better hot air fermentation.
