Description

Technical Field

[0001] The present invention belongs to the technical field of coffee machines, and particularly relates to a stirring mechanism for a coffee machine. Background Art

[0002] Coffee is a beverage made from roasted and ground coffee beans. As one of the world's three major beverages, it, together with cocoa and tea, is one of the main beverages popular in the world. With the progress of society and the development of technology, people have applied electronic technology to coffee machines, realizing the automatic control of the entire brewing process of coffee, including grinding, tamping, loading, brewing, and residue removal, thus creating coffee machines.

[0003] In existing coffee machines, stirrers are generally provided at the powder outlets of each material box. During use, powder is usually discharged while being stirred. However, since the number of material boxes is relatively large, multiple sets of stirrers need to be installed, which increases the cost and takes more time for installation. When the stirrer of one of the material boxes fails, the corresponding material box cannot be used. In addition, after the stirrer stirs, the powder usually needs to flow through pipelines into the cup. However, due to the large number of material boxes, the pipelines are prone to being disordered, and residues will remain in the pipelines. After long-term use, odors and bacteria will appear, affecting the taste of the product. Summary of the Invention

[0004] The present invention provides a stirring mechanism for a coffee machine, aiming to solve the problems that during use, powder is usually discharged while being stirred, but since the number of material boxes is relatively large, multiple sets of stirrers need to be installed, which increases the cost and takes more time for installation. When the stirrer of one of the material boxes fails, the corresponding material box cannot be used. In addition, after the stirrer stirs, the powder usually needs to flow through pipelines into the cup. However, due to the large number of material boxes, the pipelines are prone to being disordered, and residues will remain in the pipelines.

Inside the inner cavity of the closed box and on one side of the stirring rod, a rotating gear meshing with the toothed groove is rotatably arranged. At the bottom of the inner cavity of the closed box, a second motor for driving the rotating gear to rotate is arranged. At the bottom of the stirring rod and outside the closed box, a stirring disc is circularly arranged.

[0006] Preferably, a cross plate is horizontally arranged inside the inner cavity of the coffee machine main body and below the powder box. Inside the cross plate, a second threaded lead screw is rotatably arranged horizontally. On one side of the inner cavity of the cross plate, a third motor for driving the second threaded lead screw to rotate is arranged. On the surface of the second threaded lead screw, a second lead screw sleeve is slidably arranged through a thread. At the bottom of the second lead screw sleeve, a fixing piece vertically penetrating through the bottom of the cross plate is arranged. On the outside of the fixing piece, a connecting frame sleeved on the surface of the cross plate is arranged. On the top of the connecting frame, a cup gripper is horizontally arranged.

[0007] Preferably, bearing rods are horizontally arranged on both sides of the second lead screw sleeve and inside the cross plate. At the outer ends of the bearing rods, rollers are rotatably arranged. At the bottom of the inner cavity of the cross plate, tracks distributed along the direction of the second threaded lead screw are arranged, and the tracks are slidably connected with the rollers.

[0008] Preferably, sliding grooves distributed along the direction of the second threaded lead screw are opened at the top of the inner cavity of the cross plate. Inside the sliding grooves, a first slider fixedly connected with the second lead screw sleeve is slidably arranged.

[0009] Preferably, a sliding groove is vertically arranged on one side of the inner cavity of the closed box. Inside the sliding groove, a second slider fixedly connected with the first lead screw sleeve is slidably arranged.

[0010] Preferably, a strip-shaped frame is provided at the bottom of the closed box, a bidirectional threaded lead screw is horizontally and rotatably arranged in the inner cavity of the strip-shaped frame, and a fourth motor for driving the bidirectional threaded lead screw to rotate is arranged on one side of the inner cavity of the strip-shaped frame.

[0011] Preferably, bearing threaded sleeves are slidably arranged on the surface of the bidirectional threaded lead screw through threads, and two groups of bearing threaded sleeves are provided. A fixing rod extending to the outside of the strip-shaped frame is arranged on one side of each group of bearing threaded sleeves, and a fixing ring is arranged at the other end of the fixing rod.

[0012] Preferably, the fixing ring is arranged in an inward concave circular arc shape, and a cleaning sponge is arranged inside the fixing ring. A cleaning groove is formed inside the cleaning sponge, and the size of the cleaning groove is adapted to the size of the stirring disc.

[0017] (2) When the third motor is set to work, it will drive the second threaded lead screw to rotate. When the second threaded lead screw rotates, it will drive the second lead screw sleeve to move through the slideway and the first slider. When the second lead screw sleeve moves, it will drive the connecting frame to move through the fixing member. When the connecting frame moves, it will drive the cup gripper to move. The set cup gripper can clamp the cup, so that the moving cup gripper can drive the cup to move, which is convenient to move the cup under the material box. When there is powder in the cup, it can be moved under the mixing disc again through the movement of the cup gripper, and then the mixing work can be carried out by the mixing disc, improving the practicability, saving costs, being easy to use, avoiding the need for manual movement, and improving work efficiency.

[0018] (3) When the fourth motor is set to work, it will drive the double-threaded lead screw to rotate. When the double-threaded lead screw rotates, it will drive the bearing threaded sleeves to approach each other. When the bearing threaded sleeves approach each other, they will drive the fixing rings to approach each other through the fixing rods. When the fixing rings approach each other, they will drive the cleaning sponges to approach each other, so as to wrap the mixing disc by using the cleaning groove, thereby cleaning the mixing disc, avoiding the residue problem of the mixing disc and affecting the taste of different flavors of coffee, and improving the practicability.
