[0045] Reference Figures 1-6 A tea aroma-enhancing device with uniform heating includes a housing 1 with a cavity 11. A heating element is installed inside the housing 1, and the heat from the heating element is transferred to the cavity 11. This is a conventional setting of existing aroma-enhancing devices, so it will not be described in detail in this application. A shelf 2 is installed inside the cavity 11, and a door 12 is hinged to the housing 1. The cavity 11 can be opened or closed by rotating the door 12. The housing 1 provides a relatively closed space for the entire aroma-enhancing process, which facilitates the control of internal environmental conditions such as temperature and humidity. The design of the door 12 makes it convenient for operators to put tea leaves into the shelf 2 inside the cavity 11 and to take out the tea leaves after the aroma-enhancing process is completed.
[0046] The housing 1 is equipped with a first motor 13. The piston end of the first motor 13 is connected to the shelf 2 through a connecting part, so that the shelf 2 can rotate in a circle. By rotating the shelf 2, the tea leaves can receive heat in different positions, avoiding uneven heating in some areas and improving the overall uniformity of heating of the tea leaves, thereby enhancing the aroma.
[0047] The shelf 2 has an opening on one side, and a displacement drive assembly 3 is installed on the opening. The displacement drive assembly 3 includes a support 31, which is connected to the shelf 2. The support 31 has a receiving groove and a lead screw component 32 is rotatably mounted on it. One end of the lead screw component 32 extends to the outside of the support 31 and is connected to a second motor 33. The second motor 33 and the lead screw component 32 are connected by a coupling. A bearing seat 34 is installed on the lead screw component 32, and several spaced placement components 4 are installed on the bearing seat 34. The placement component 4 includes an annular rod 41, with a connecting rod 42 on the outer periphery of the annular rod 41 and connected to the support seat 34. A tea tray 5 is installed on the annular rod 41. Through the cooperation of the screw component 32 and the placement component 4, the tea tray 5 can move relative to the screw component 32 along its length. The movement of the support seat 34 can cause the placement component 4 and the tea tray 5 installed on it to move accordingly, simulating the shaking of tea leaves during manual operation, so that the tea leaves piled inside can be heated during the shaking process.
[0048] The tea tray 5 is also equipped with a stirring component 6, which includes a support shaft 61. The support shaft 61 is rotatably mounted on the tea tray 5. The support shaft 61 has a sleeve 611. A scraper 62 is installed on the outer periphery of the sleeve 611. Through the cooperation of the scraper 62 and the sleeve 611, the scraper can rotate along the support shaft 61, thereby further stirring the tea leaves on the tea tray 5.
[0049] Based on the above structure, the tea tray 5 containing tea leaves is placed on the annular rod 41, and the annular rod 41 is connected to the support seat 34 via the connecting rod 42. The closure of the box body 1 by the box door 12 heats the interior of the cavity 11. Since the support seat 34 is mounted on the lead screw component 32 connected to the second motor 33, when the second motor 33 drives, the support seat 34 moves in the rotation direction of the lead screw component 32. During the movement, the tea tray 5 moves synchronously. Through the reciprocating rotation of the lead screw component 32, the tea tray 5 is vertically shaken up and down, thus simulating the shaking of the tea tray 5 by hand, allowing the tea leaves piled inside the tea tray 5 to come into contact with heat during the shaking process. This achieves heating, and the shelf 2, which is equipped with the displacement drive component 3, is connected to the first motor 13. The shelf 2 rotates in a circle according to the rotation direction of the first motor 13. During the rotation, it can shake the tea leaves in the tea tray 5, thereby further heating the tea leaves. At the same time, the stirring component 6 on the tea tray 5 can move the tea leaves by rotating the scraper 62 on the tea tray 5, thereby further ensuring that the tea leaves are heated evenly. Through the cooperation of the displacement drive component 3 and the stirring component 6, the tea tray 5 containing the tea leaves can be driven to move back and forth, thereby shaking and dispersing the tea leaves and moving them, thus avoiding the problem of uneven heating caused by some tea leaves always being inside the whole tea leaves.
[0050] Both the first motor 13 and the second motor 33 mentioned above are high-temperature resistant servo drive motors in the prior art.
[0051] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 The shelf 2 has a through groove 21 on the side away from the opening. A guide rod 22 is installed in the through groove 21. A slide 23 is movably installed on the guide rod 22. The length of the slide 23 is the same as the length of the support seat 34. Two sets of connecting rods 42 are provided and are located on both sides of the annular rod 41 respectively.
[0052] Two sets of connecting rods 42 are connected to the slide 23 and the bearing seat 34 respectively, so that both ends of the ring rod 41 can be supported. When the bearing seat 34 moves the ring rod 41 with the cooperation of the screw component 32, the slide 23 moves relative to the guide rod 22 along the length direction. The screw component 32 drives the bearing seat 34 to move, which in turn drives the ring rod 41 to move. At the same time, the slide 23 moves on the guide rod 22, providing guidance and support for the movement of the ring rod 41, ensuring the stability and accuracy of the movement of the ring rod 41, and allowing the tea tray 5 to move smoothly. This helps to adjust the position of the tea leaves during the aroma enhancement process and promotes uniform heating of the tea leaves.
[0053] In one embodiment, reference is made to Figure 1and Figure 4 The stirring component 6 also includes a third motor 63, which is a high-temperature servo motor in the prior art. The third motor 63 is located at the bottom of the tea tray 5. The output end of the third motor 63 is connected to the support shaft 61 through a coupling. Several scraper plates 62 are provided and are evenly distributed along the circumference of the sleeve 611. With the cooperation of the third motor 63, the scraper plates 62 can rotate in a circle around the support shaft 61. The third motor 63 drives the support shaft 61 to rotate, thereby driving the scraper plates 62 to make a circular motion. During the rotation, the scraper plates 62 can turn the tea leaves on the tea tray 5, so that the tea leaves constantly change position during the aroma enhancement process, avoiding uneven heating in some areas, improving the overall heating uniformity of the tea leaves, and enhancing the aroma enhancement effect.
[0054] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 6 Both the support seat 34 and the slide seat 23 are provided with several spaced mounting holes 7. When the annular rod 41 is connected to the slide seat 23 and the support seat 34 respectively, the two sets of connecting rods 42 are embedded in the mounting holes 7 respectively. The mounting holes 7 provide the mounting position for the connecting rods 42, making the connection between the annular rod 41 and the slide seat 23 and the support seat 34 more stable, ensuring that the connection between the components will not loosen during the operation of the device, and ensuring the stability and reliability of the entire structure. In addition, the number of tea trays 5 can be adjusted according to the actual situation, thereby changing the spacing between two adjacent sets of tea trays 5.
[0055] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 5 A temperature sensing component 8 is installed on one side of the housing 1. The temperature sensing component 8 is a temperature sensor with network connectivity in the prior art. The detection end of the temperature sensing component 8 is located inside the cavity 11. The temperature sensing component 8 can monitor the temperature inside the cavity 11 in real time. The operator can adjust the heating parameters of the aroma-enhancing device in a timely manner based on the monitored temperature data to ensure that the temperature inside the cavity 11 is always within a suitable range for tea aroma enhancement, which helps to improve the quality and stability of tea aroma enhancement.
[0056] In one embodiment, reference is made to Figure 1 and Figure 4 The tea tray 5 has evenly distributed mesh holes 51, which help the heat to circulate among the tea leaves, allowing the tea leaves to be heated better. The scraper 62 is located above the mesh holes 51, and inclined plates 621 are provided on both sides of the bottom of the scraper 62. The bottom end of the inclined plate 621 is in contact with the end face of the mesh hole 51, and an angle is formed between the inclined plate 621 and the scraper 62. This allows the scraper 62 to better turn the tea leaves when it rotates, preventing the tea leaves from piling up in the mesh holes 51 and further ensuring that the tea leaves are heated evenly.
[0057] In one embodiment, reference is made to Figure 1 and Figure 4 The outer periphery of the tea tray 5 is provided with a guide plate 52, which has an inclined end 521 located above the mesh 51. The guide plate 52 can block the tea leaves on the tea tray 5 when they move and shake, thus preventing the tea leaves from falling off the outer edge of the tea tray 5. The inclined end 521 can also block the tea leaves from above the tea tray 5. The bottom of the tea tray 5 is provided with a groove 53, which is an arc-shaped structure that fits the shape of the ring rod 41. By engaging the groove 53 with the outer periphery of the ring rod 41, the tea tray 5 is placed inside the shelf 2, making it easy to install and remove the tea tray 5, and easy to clean and replace the tea tray 5.
[0058] In one embodiment, reference is made to Figures 1-3 The bottom of the cavity 11 is provided with a shaft 111, and the bottom of the shelf 2 is fitted onto the shaft 111. The shaft 111 provides the shelf 2 with a support and a rotation axis, allowing the shelf 2 to rotate around the shaft 111 to a certain extent, increasing the positional change of the tea during the aroma enhancement process and further improving the uniformity of the tea's heating.
[0059] In one embodiment, reference is made to Figures 1-3 A sealing gasket 121 is provided on the side of the door 12 facing the cavity 11. The sealing gasket 121 is made of high-temperature resistant rubber material. The size and area of the sealing gasket 121 are the same as those of the cavity 11. When the door 12 covers the cavity 11, part of the sealing gasket 121 is embedded in the cavity 11. The sealing gasket 121 can enhance the sealing between the door 12 and the cavity 11, achieve double sealing, reduce heat loss, ensure the temperature stability inside the cavity 11, improve energy utilization efficiency, and at the same time prevent external dust and other impurities from entering the cavity 11 and affecting the quality of tea aroma enhancement.
