Abstract
Description
Technical Field
[0001] This utility model relates to the field of tea dust removal technology, and in particular to a tea surface dust removal device. Background Technology
[0002] Dust removal from tea leaves is a crucial step in ensuring tea quality. It involves using physical methods to remove impurities and dust from the tea leaves. During tea processing, tea leaves easily absorb dust and other impurities due to contact with the external environment. Dust removal not only improves the appearance and hygiene standards of the tea leaves but also prevents these impurities from affecting their flavor and aroma.
[0003] Currently, when using wind to blow away dust from tea leaves, the wind continuously blows across the surface of the tea leaves. When the wind is weak, it is impossible to clean a large quantity of tea leaves. If the wind is too strong, the tea leaves may be held in one place by the wind. Therefore, choosing the right wind force is difficult and it is impossible to ensure that the tea leaves are thoroughly cleaned.
[0004] Therefore, a dust removal device for tea surface is proposed to solve or alleviate the above problems. Utility Model Content

A sliding groove communicating with its inner ring is opened on one outer wall of the frame 4. Several sets of slide rails are fixedly connected to the inner ring of the frame 4. Each set of slide rails has two slide rails. The two slide rails of the same set are located on both sides of the sliding groove. The net bag 5 is slidably connected to the slide rails on both sides through the sliding groove. The cross-sectional area of the end plate 6 is larger than the cross-sectional area of the sliding groove. A handle 7 is fixedly connected to the side of the end plate 6 away from the net bag 5.
[0031] The base 1 has a through slot that communicates with the outside. The air guiding component includes a fan 2 and a heating wire 14. The heating wire 14 is installed inside the fan 2. The air inlet of the fan 2 is connected to the through slot, and the air outlet of the fan 2 is set towards the frame 4.
[0032] like Figure 2 As shown, it also includes a power supply. A push-button switch 13 is fixedly connected to the frame 4. The power supply, push-button switch 13, and heating wire 14 are connected in series. A trigger circuit 15 is connected in parallel between the push-button switch 13 and the heating wire 14. The trigger circuit 15 outputs a trigger signal after the push-button switch 13 is closed. The output terminal of the trigger circuit 15 is coupled to a first timing circuit 16. The first timing circuit 16 starts timing in response to the trigger signal and outputs a low-level first timing signal after the timing ends. The output terminal of the first timing circuit 16 is coupled to a second timing circuit 17. The second timing circuit 17 starts timing in response to the low-level first timing signal and outputs a high-level second timing signal within the timing period. The second timing circuit 17 is coupled to a switch circuit 18. The power supply is connected to the power supply. The source is coupled, the controlled terminal of the switching circuit 18 is coupled to the output terminal of the second timing circuit 17, the ground terminal of the switching circuit 18 is connected in series with the fan 2 and then grounded, the switching circuit 18 responds to the high level of the second timing circuit 17 to control the fan 2 to be energized, the trigger circuit 15 includes an Rs flip-flop, the first timing circuit 16 includes a minimum system based on a 555 timer chip and an inverter, the inverter is coupled to the output terminal of the minimum system based on a 555 timer chip in the first timing circuit 16, the second timing circuit 17 includes a minimum system based on a 555 timer chip, the switching circuit 18 includes a transistor switch, the base of the transistor switch is the controlled terminal of the switching circuit 18, the collector of the transistor switch is the energized terminal of the switching circuit 18, and the emitter of the transistor switch is the ground terminal of the switching circuit 18.
[0033] When people need to use this device to remove dust from the surface of tea leaves, they only need to load the tea leaves into the net bag 5, ensuring that the tea leaves do not exceed the top surface of the net bag 5, and then insert the net bag 5 into the sliding groove, so that the net bag 5 slides into the slide rail, thereby allowing the net bag 5 to enter the frame 4, and ensuring that the end plate 6 is in contact with the outer wall of the frame 4. During this process, the operator can control the displacement of the net bag 5 by holding the handle 7.
[0034] Then, the operator can manually press button switch 13. After button switch 13 is closed, the power supply directly supplies power to heating wire 14, causing heating wire 14 to heat and dry the air inside fan 2. Fan 2 does not start immediately. Instead, after the button is closed, trigger circuit 15 sends a low-level trigger signal to first timing circuit 16. Since the first timing circuit 16 is a 555 chip, it starts timing after responding to the low-level trigger signal and outputs a low-level first timing signal after the timing ends. At this time, the first timing circuit 16 has a certain delay effect. Then, the second timing circuit 17 responds to the low-level first timing signal and starts timing, outputting a low-level first timing signal within the timing time. During the timing period, the switching circuit 18 receives the high-level second timing signal, which enables the fan 2 to receive power and operate for a certain period of time. During this timing period, the fan 2 guides the outside air through the slot towards the bottom of the frame 4, allowing the dry hot air to penetrate the frame 4 upwards and blow the tea leaves in the mesh bag 5 up, so that the tea leaves can be lifted up in the dust removal space. During this process, the operator can observe the situation through the circumferential transparent plate 10. When the tea leaves are blown up, the air can carry away the dust on their surface, and the dust can be adsorbed by the activated carbon tube 12, thus ensuring that when the tea leaves fall back down by their own weight, the dust will not re-attach to the tea leaves.
[0035] When the adsorption effect of the activated carbon tube 12 deteriorates, a new activated carbon tube 12 can be replaced to ensure that the dust removal effect of the device does not decrease. After the dust removal is completed, the tea leaves will fall back into the net bag 5. The operator only needs to hold the handle 7 and take the net bag 5 out of the frame 4 to complete the unloading action.
[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
