[0049] Reference Figure 3 and Figure 4As shown, the inner sleeve 200 and the outer sleeve 100 are arranged inside and outside, and the inner sleeve 200 and the outer sleeve 100 are coaxially arranged and rotatably connected. Under the driving action of the driving mechanism 400, the inner sleeve 200 and the stirring shaft 300 are driven to rotate in the opposite direction. The tea leaves are placed in the inner sleeve 200. As the inner sleeve 200 and the stirring shaft 300 rotate in the opposite direction, the tea leaves are turned over. Under the heating action of the heater 600, the tea leaves are stir-fried and withered. The tea stir-frying and withering device also has a heating element on the inner wall surface of the inner sleeve 200. A plurality of turning parts 210 are provided, and the plurality of turning parts 210 and the plurality of stirring blades 320 are staggeredly arranged along the axial direction. The turning part 210 includes a plurality of circumferentially arranged protrusions 211. The setting of the protrusions 211, in coordination with the rotation of the inner sleeve 200, is conducive to enhancing the turning effect of the tea leaves, so that the tea pile in the inner sleeve 200 is fully turned over, and the tea leaves are heated more evenly. The staggered arrangement of the stirring blades 320 and the turning part 210 is conducive to reducing the turning dead angle of the inner sleeve 200, so as to enhance the withering effect of the tea leaves.

[0050] Reference Figure 3 and Figure 4 As shown, specifically, the inner sleeve 200 and the outer sleeve 100 are both cylindrical, and under the driving action of the driving mechanism 400, the inner sleeve 200 rotates, and the stirring function of the tea pile is realized under the cooperation of the flipping part 210 and the stirring blade 320. A rotating track is provided at the side wall of the outer sleeve 100, and the end of the inner sleeve 200 is embedded and connected in the rotating track, so as to realize the rotation connection between the inner sleeve 200 and the outer sleeve 100.

[0051] Reference Figure 3 and Figure 4 As shown, refer to Figure 1 As shown, it is understandable that the present invention further includes a heater 600 , which is disposed between the inner sleeve 200 and the outer sleeve 100 to heat the inner sleeve 200 .

[0052] Reference Figure 3 and Figure 4 As shown, the heater 600 of the tea stir-frying and withering device is arranged between the inner sleeve 200 and the outer sleeve 100, so that the heat provided by the heater 600 can fully heat the inner sleeve 200, thereby making the tea leaves in the inner sleeve 200 heated more evenly, and under the driving action of the driving mechanism 400, the functions of stir-frying and withering the tea leaves are realized.

[0053] Reference Figure 3 and Figure 4As shown, specifically, the heater 600 can be a resistance wire heater, which is spirally arranged around the outer circumference of the inner sleeve 200, and provides heat to the tea leaves inside the inner sleeve 200 through resistance heating, and cooperates with the stirring action of the stirring shaft 300 to achieve the functions of stir-frying and withering the tea leaves.

[0054] Reference Figure 3 and Figure 4 As shown, it is understandable that, considering that some tea leaves may be rolled into balls, which is not conducive to achieving uniform heating of the tea leaves, the tea leaf stir-frying and withering device also includes a fan 500, a gas flow path 330 is provided in the stirring shaft 300, and an air outlet 331 is provided at one end of the stirring blade 320 adjacent to the inner sleeve 200, and the air outlet 331 and the fan 500 are both connected to the gas flow path 330.

[0055] Reference Figure 3 and Figure 4 As shown, as the stirring shaft 300 rotates, the stirring blades 320 stir the tea pile, and the fan 500 operates, and the air outlet 331 of the stirring blades 320 simultaneously ejects gas. The air jet is used to break up the tea leaves that have been kneaded into a ball, so that the tea leaves are dispersed more evenly, which is helpful to enhance the turning effect of the tea leaves, so that the tea leaves are evenly heated and withered.

[0056] Reference Figure 3 and Figure 4 As shown, specifically, the fan 500 can be arranged at one end of the outer sleeve 100 away from the driving mechanism 400 and connected to the transmission rod 310. Considering that the transmission rod 310 needs to make a rotational motion, the air outlet of the fan 500 can be connected to the transmission rod 310 through a rotating joint, thereby avoiding disturbance of the fan 500 caused by the rotation of the stirring shaft 300.

[0057] Reference Figure 3 and Figure 4 As shown, it can be understood that the stirring blade 320 is arranged at a right angle to the transmission rod 310 and is located at the same axial position of the transmission rod 310. The transmission rod 310 can be connected to multiple circumferentially arranged stirring blades 320 to achieve the turning effect of the tea pile under the driving action of the driving mechanism 400.

[0058] Reference Figure 3 and Figure 4 As shown, the stirring blade 320 includes a rod body and blades. The two ends of the rod body are respectively connected to the transmission rod 310 and the blades. The blades are located at the end away from the transmission rod 310. The setting of the blades is conducive to increasing the contact area between the stirring blade 320 and the tea pile, thereby enhancing the turning effect of the tea leaves.

[0059] Reference Figure 3 and Figure 4As shown, it can be understood that the air outlet 331 is arranged toward the turning part 210. When the fan 500 is operating, gas can be ejected from the air outlet 331. Under the pressure of the gas, part of the tea leaves are moved toward the turning part 210. Under the driving action of the driving mechanism 400, the inner sleeve 200 and the stirring shaft 300 rotate in opposite directions, and the turning part 210 rotates synchronously with the inner sleeve 200. The setting of the protrusion 211 is conducive to enhancing the turning effect of the tea leaves, so that the tea pile in the inner sleeve 200 is fully turned over, and the tea leaves are heated more evenly. The staggered arrangement of the stirring leaves 320 and the turning part 210 is conducive to reducing the turning dead angle of the inner sleeve 200, so as to enhance the withering effect of the tea leaves.

[0060] Reference Figure 3 and Figure 4 As shown, specifically, taking the two ends of the transmission rod 310 extending left and right as an example, the left end or the right end of the blade is provided with an air outlet 331, the transmission rod 310 is provided with a first flow channel, and the rod body is provided with a second flow channel. The first flow channel and the second flow channel jointly define an air outlet path, and the air outlet path is connected to the air outlet 331, under the variable pressure action of the fan 500, the jet function of the tea leaves is realized.

[0061] It should be understood that in another embodiment, the fan 500 is connected to the transmission rod 310 through an extension tube, and the extension tube passes through the heating area of ​​the heater 600, that is, the heater 600 can simultaneously heat the air outlet of the fan 500, and use the hot air to break up the tea leaves that have been kneaded into balls, which is beneficial to enhancing the withering effect of the tea leaves.

[0062] Reference Figure 3 and Figure 4 As shown, it can be understood that, in the present embodiment, a first distance is provided between the stirring blade 320 and the inner sleeve 200, and the first distance is smaller than the thickness of the protrusion 211, which is beneficial to increase the turning area of ​​the tea leaves by the stirring blade 320, and is beneficial to reduce the turning dead zone of the tea leaves, and is beneficial to enhance the turning effect of the tea leaves, so that the tea pile in the inner sleeve 200 is fully turned, and the tea leaves are heated more evenly. Through the staggered arrangement of the stirring blade 320 and the turning part 210, it is beneficial to reduce the turning dead angle of the inner sleeve 200, so as to enhance the withering effect of the tea leaves.

[0063] It is understandable that, taking into account the problem of finely divided tea leaves clogging the air outlet 331, the stirring blade 320 is connected to a filter at one end close to the inner wall of the inner sleeve 200, and the filter covers the air outlet 331. The setting of the filter helps to block finely divided tea leaves from entering the gas flow path 330 while ensuring the air outlet 331 to pass through, thereby ensuring the smooth flow of the gas flow path 330 and realizing the function of jetting to break up tea clumps.

[0064] It should be noted that the mesh size of the filter can be set according to the size of the tea leaves, thereby reducing or avoiding the problem of tea leaves blocking the air outlet.

[0065] It is understandable that, considering that the humidity of the tea leaves needs to be controlled during the withering of the tea leaves, the tea leaf turning and withering device also includes a humidity sensor, a dehumidifier and a controller. The humidity sensor is used to detect the internal humidity of the inner sleeve 200. The humidity sensor and the dehumidifier are both connected to the controller. The dehumidifier is used to reduce the internal humidity of the inner sleeve 200.

[0066] When the internal humidity of the inner sleeve 200 reaches the preset humidity, the controller can control the operation of the dehumidifier to reduce the internal humidity of the inner sleeve 200 through the dehumidifier. That is, the tea stir-frying and withering device can assist in controlling the humidity of the tea leaves and improve the withering effect of the tea leaves through the setting of the dehumidifier.

[0067] It should be noted that the working principle of the dehumidifier belongs to the prior art and will not be described in detail here. The control principle of the controller belongs to the prior art. For the controller, the utility model mainly protects its connection method.

[0068] It is understandable that, considering the pressure control of the inner sleeve 200, the tea stir-frying and withering device also includes a pressure sensor and a pressure relief valve. The pressure sensor is used to detect the internal pressure of the inner sleeve 200. The pressure sensor and the pressure relief valve are both electrically connected to the controller. The pressure relief valve is used to connect the inner sleeve 200 with the atmosphere.

[0069] When the pressure sensor detects that the internal pressure of the inner sleeve 200 reaches the preset pressure, the pressure sensor is triggered and the controller opens the pressure relief valve, thereby controlling the internal pressure of the inner sleeve 200 within a preset range, which is helpful in assisting the pressure control of the inner sleeve 200, thereby reducing the user's workload and improving the withering effect of tea leaves.

[0070] It should be noted that the structure of the pressure relief valve is far from the prior art and will not be described in detail here.

[0071] Reference Figure 1 and Figure 3 As shown, it can be understood that the driving mechanism 400 includes a driving gear 430, a driving motor 410 and a synchronous belt 420, the driving motor 410 is connected to the transmission rod 310, the transmission rod 310 and the driving gear 430 are both connected to the synchronous belt 420, and a gear ring is provided on the outer periphery of the inner sleeve 200, which is meshingly connected to the driving gear 430.

[0072] Reference Figure 1 and Figure 3As shown, the driving motor 410 is connected to the transmission rod 310 to drive the stirring shaft 300 to rotate. The transmission rod 310 and the driving gear 430 are both connected to the synchronous belt 420. Under the connection of the synchronous belt 420, the synchronous rotation of the transmission rod 310 and the driving gear 430 is realized. The outer periphery of the inner sleeve 200 is provided with a ring gear, and the ring gear is meshingly connected with the driving gear 430. As the driving gear 430 rotates, the ring gear and the driving gear 430 rotate in the opposite direction, that is, the inner sleeve 200 and the driving gear 430 rotate in the opposite direction to realize the reverse rotation of the inner sleeve 200 and the stirring shaft 300, which is beneficial to enhance the turning effect of the tea leaves, so that the tea leaves are evenly heated and the withering effect of the tea leaves is improved.

[0073] Reference Figure 1 and Figure 3 As shown, the driving motor 410 may be a forward and reverse motor. By switching the forward and reverse rotation of the driving motor 410, it is helpful to enhance the turning effect of the tea leaves, so as to improve the stir-frying and withering effects of the tea leaves.

[0074] Reference Figure 1 and Figure 3 As shown, it is understandable that, taking into account the defect of uneven distribution of tea leaves in the axial direction of the inner sleeve 200, the tea leaf stir-frying and withering device also includes a swing mechanism 800, and the outer sleeve 100 is rotatably connected to the seat body 700. The swing mechanism 800 is transmission-connected to the outer sleeve 100 to drive the outer sleeve 100 to swing back and forth. The reciprocating swing of the outer sleeve 100 is beneficial to the axial reciprocating movement of the tea leaves along the inner sleeve 200, which is beneficial to uniform distribution of the tea leaves in the inner sleeve 200, so as to reduce the dead zone of the tea leaves being turned over, and to enhance the turning effect of the tea leaves, so that the tea leaves are evenly heated and withered.

[0075] Reference Figure 1 and Figure 3 As shown, specifically, the outer sleeve 100 is rotatably connected to the seat body 700 along the middle part of the axial direction, and the swing mechanism 800 includes two cylinders 810 and a connecting rod 820. The two cylinders 810 are respectively located at the left end and the right end of the outer sleeve 100, and the two cylinders 810 are respectively rotatably connected to the lower end of the outer sleeve 100 through two connecting rods 820. Through the coordinated extension and retraction of the two cylinders 810, the reciprocating swing of the outer sleeve 100 can be realized.

[0076] Reference Figure 1 and Figure 3 As shown, for example, when the left end cylinder 810 contracts, the right end cylinder 810 extends, so that the outer sleeve 100 tilts downward to the left side. When the left end cylinder 810 extends and the right end cylinder 810 contracts, the outer sleeve 100 tilts downward to the right side.
