[0039] 4. The tea fermentation machine has a toggle mechanism. When the resistance block contacts the spherical groove and is in the spherical groove and deflects, the rotating rod will deflect to achieve a deflection effect around the rotating rod, thereby achieving a better toggle effect on the tea leaves.

DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] See also Figure 1-8 One embodiment of the present invention is: a tea fermentation machine, comprising a fermentation cylinder 1, and further comprising:

[0051] Two doors 2 are respectively installed on the front of the fermentation cylinder 1;

[0052] A plurality of legs 3 are fixedly connected to the bottom of the fermentation cylinder 1 in an equal circumference;

[0053] The rotating mechanism 4 is arranged inside the fermentation cylinder 1 and is used for rotating and fermenting tea leaves;

[0054] The toggling mechanism 5 is arranged on one side of the rotating mechanism 4 and is used to toggle the rotating tea leaves;

[0055] Two sets of heating plates 6 are symmetrically connected to both sides of the inner wall of the fermentation cylinder 1;

[0056] Wherein, the rotating mechanism 4 comprises:

[0057] The rotating shaft 43 has two ends rotatably connected to the inner wall of the fermentation cylinder 1 through bearings;

[0058] The motor is installed on the top of the fermentation cylinder 1 and is fixedly connected to the top of the rotating shaft 43, and is used to drive the rotating shaft 43 to rotate;

[0059] The tea tray 41 is mounted on the outer wall of the rotating shaft 43 and is used to rotate along with the rotating shaft 43 .

[0060] The rotating mechanism 4 also includes:

[0061] The slot 42 is formed on the outer wall of the tea tray 41, and a plurality of ventilation holes are formed on the tea tray 41. The ventilation holes on the tea tray 41 are designed to facilitate air circulation and promote gas exchange during the fermentation process.

[0062] A carrying ring 44 is fixedly connected to the outer wall of the rotating shaft 43 and is used to support the tea tray 41;

[0063] The insert rod 45 is fixedly connected to the outer wall of the rotating shaft 43 and is located on the bearing ring 44, and is used to block the slot 42 to push the tea tray 41 to rotate along with the rotating shaft 43;

[0064] The upper limit cylinder 46 is fixedly sleeved on the outer wall of the rotating shaft 43 and is used to limit the tea tray 41 .

[0065] Working principle: When fermenting tea leaves, first open the two compartment doors 2, and place the tea tray 41 to be fermented on the rotating shaft 43 in turn, and penetrate into the tea tray 41 through the slot 42. At this time, until the tea tray 41 falls onto the supporting ring 44, the slot 42 is directly aligned with the insertion rod 45 to achieve fixation, and then the fixing is achieved by driving the rotating shaft 43 to rotate through the motor to drive the tea tray 41 to rotate rapidly, so that the tea leaves on the tea tray 41 can be controlled to be evenly heated and fermented.

[0066] See also Figure 1-8 Based on the above embodiment, in another embodiment of the present invention, the toggle mechanism 5 includes:

[0067] A rotating rod 51, one end of which is rotatably connected to the inner wall of the fermentation cylinder 1;

[0068] The lower connecting rod 52 is fixedly connected to the lower part of the rotating rod 51, and the lower connecting rod 52 is L-shaped;

[0069] A lever 53 movably connected to the outer wall of the lower connecting rod 52;

[0070] A plurality of arc-shaped paddles 54 are fixedly connected to the outer wall of the lever 53 and are used to flip the tea leaves. The design of the paddle mechanism 5 prevents the tea leaves from piling up during the fermentation process, and the configuration of the lever 53 and the arc-shaped paddles 54 ensures that the tea leaves are evenly distributed throughout the fermentation cylinder 1;

[0071] The outer wall of the lower connecting rod 52 is fixedly connected to two limit bars, and the inner wall of the lever 53 is in contact with the two limit bars and the outer wall of the lower connecting rod 52;

[0072] A spring 55 is disposed on the inner wall of the lever 53 , and the spring 55 is used to push the lever 53 to move toward a side away from the lower connecting rod 52 .

[0073] The outer wall of the upper limit cylinder 46 is provided with a plurality of grooves 563 , and a side of the lever 53 away from the lower connecting rod 52 is in contact with the grooves 563 and the outer wall of the upper limit cylinder 46 .

[0074] The toggle mechanism 5 also includes:

[0075] The abutment block 56 is fixedly connected to one end of the rotating rod 51 and moves on the annular groove 561 formed on the outer wall of the upper limit cylinder 46;

[0076] A plurality of spherical grooves 562 are provided on the inner wall of the annular groove 561;

[0077] The bottom of the abutment block 56 is spherical and fits in the annular groove 561 and moves on the annular groove 561 .

[0078] A movable groove is formed on the outer wall of the upper limit cylinder 46 , and penetrates into one of the spherical grooves 562 , and is used to lock the spherical groove 562 .

[0079] Two supports 7 are fixedly connected to the top of the rotating rod 51, and two atomization tubes 8 are fixedly connected to the outer wall of the support 7. A hose 9 is fixedly connected to one side of the atomization tube 8, and the other end of the hose 9 is fixedly passed through the fermentation cylinder 1 and extends downward to be connected to an external atomizer.

[0080] Working principle: When the tea tray 41 is placed on the carrying ring 44 and contacts the abutment block 56, the abutment block 56 contacts the spherical groove 563, thereby supporting the rotating rod 51;

[0081] Then, when the tea tray 41 rotates, the tea leaves contact the arc-shaped plucking piece 54 to move the tea leaves, thereby preventing the tea leaves from being piled up and affecting the fermentation of the tea leaves. At the same time, when the tea tray 41 continues to rotate, the plucking rod 53 continuously contacts the outer wall of the upper limit cylinder 46 and under the resistance of the spring 55, the plucking rod 53 continuously moves on the lower connecting rod 52 to change the plucking position, thereby improving the plucking effect of the tea leaves.

[0082] Furthermore, when the tea tray 41 rotates, the abutment block 56 contacts the spherical groove 562. When the abutment block 56 is in the spherical groove 562 and deflects, the rotating rod 51 deflects to achieve a deflection effect around the rotating rod 51, thereby achieving a better effect of moving the tea leaves.

[0083] When the gas atomized by the external atomizer enters the atomizing tube 8 through the hose 9 and is sprayed, the atomizing tube 8 can be deflected and moved accordingly to achieve better control of the humidity inside the fermentation cylinder 1.

[0084] The present invention provides a tea fermentation machine. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
