[0041] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0042] See also Figures 1-16The ice cream machine comprises a main body 1, a barrel 2 is provided in the main body 1, the barrel 2 has a discharge port 21, a stirring mechanism is provided in the barrel 2 for stirring and pushing the ice cream to the discharge port 21, a joint body 3 is connected to the position of the barrel 2 corresponding to the discharge port 21, a movable valve 31 is provided on the joint body 3 corresponding to the discharge port 21, the joint body 3 is movably connected to the handle 32, one end of the handle 32 extends toward the outside of the joint body 3, and a transmission mechanism is provided between the handle 32 and the movable valve 31, so that the movable valve 31 opens the discharge port 21, the joint body 3 and the barrel 2 are detachably separated, the joint body 3 and the barrel 2 are fixed by a limit mechanism, and the stirring mechanism can push the ice cream to the discharge port 21, thereby improving the efficiency of the user in taking the ice cream. At the same time, the joint body 3 and the discharge port 21 can be quickly disassembled and assembled, so that the assembly of the joint body 3 as a whole and the discharge port 21 is more rapid, and it is convenient for the user to clean the joint body 3 and the discharge port 21.

[0043] The transmission mechanism includes a connecting rod 33, the handle 32 and the joint body 3 are movably connected via a first rotating shaft 341, one end of the connecting rod 33 and the handle 32 are movably connected via a second rotating shaft 342, the other end of the connecting rod 33 and the movable valve 31 are movably connected via a third rotating shaft 343, and the movable valve 31 and the joint body 3 are movably connected via a fourth rotating shaft 344.

[0044] The handle 32 swings around the first rotation axis 341 to cause the connecting rod 33 to swing away from the discharge port 21 . The swing of the connecting rod 33 away from the discharge port 21 causes the movable valve 31 to open the discharge port 21 .

[0045] The fourth rotating shaft 344 is connected to a return torsion spring 35, through which the movable valve 31 can close the discharge port 21. When the user stops applying external force to the handle 32, the return torsion spring 35 can automatically reset the movable valve 31 and improve the sealing performance of the movable valve 31 when closing the discharge port 21, further reducing the chance of accidental leakage of ice cream.

[0046] The stirring mechanism includes a driving motor 4, a first stirring blade 41 and a second stirring blade 42 arranged on the outside of the first stirring blade 41. A transmission component is provided between the driving motor 4 and the first stirring blade 41 and the second stirring blade 42. The driving motor 4 causes the first stirring blade 41 and the second stirring blade 42 to rotate around the center position of the transmission component respectively through the transmission component. The first stirring blade 41 and the second stirring blade 42 can stir and blend the food raw materials at the same time under the action of the driving motor 4 and the transmission component. Since the second stirring blade 42 is arranged on the outside of the first stirring blade 41, the stirring range of the food raw materials can be relatively increased, which is beneficial to improving the production efficiency of the equipment.

[0047] Furthermore, there is no need to configure two additional driving devices for the first stirring blade 41 and the second stirring blade 42 , thereby simplifying the overall structure of the device and reducing the production cost of the device.

[0048] The first stirring blade 41 includes a central rotating shaft 411 and a spiral blade 412. The central rotating shaft 411 is connected to the transmission assembly. The spiral blade 412 is arranged on the outside of the central rotating shaft 411 in a spiral shape. The spiral blade 412 is fixedly connected to the central rotating shaft 411. The driving motor 4 can drive the spiral blade 412 to rotate in the forward direction through the central rotating shaft 411. During the forward rotation of the spiral blade 412, the food can be stirred and pushed downward to improve the food discharge efficiency.

[0049] The second stirring blade 42 includes a transmission disk 421 and an outer blade 422. The transmission disk 421 is connected to the transmission assembly. The outer blade 422 is arranged in the radial outer direction of the first stirring blade 41. The outer blade 422 is fixedly connected to the transmission disk 421. The driving motor 4 can drive the outer blade 422 to rotate through the transmission assembly and the transmission disk 421. The rotation of the outer blade 422 can stir the food in the radial outer direction of the first stirring blade 41, thereby relatively increasing the stirring range of the food raw materials.

[0050] The outer blades 422 are provided with a scraping bevel 4221 at the front side relative to the rotation direction of the outer blades 422. The scraping bevel 4221 is inclined from the inside to the outside along the rotation direction of the outer blades 422. The outer blades 422 can scrape the food ingredients off the wall of the barrel 2 through the scraping bevel 4221, reducing the chance of food ingredients remaining on the barrel wall, thereby improving the efficiency of stirring the food ingredients and reducing the chance of hygiene problems caused by food ingredients remaining on the barrel wall for a long time.

[0051] The second stirring blade 42 also includes a limiting ring 423, which is arranged on the outer side of the lower section of the spiral blade 412. The limiting ring 423 is fixedly connected to the outer blade 422. The limiting ring 423 can improve the structural stability of the outer blade 422 and reduce the chance of deformation of the outer blade 422. At the same time, the limiting ring 423 can make the food raw materials more concentrated when the spiral blade 412 pushes the food raw materials downward, thereby further improving the food discharge efficiency.

[0052] A guide inclined plate 424 is provided between the lower side of the outer blade 422 and the limit ring 423. The guide inclined plate 424 is tilted downward along the rotation direction of the outer blade 422, so that the food materials between the lower side of the outer blade 422 and the lower limit ring 423 can be lifted up again and stirred again, which can prevent the food materials from staying between the lower side of the outer blade 422 and the lower limit ring 423 for a long time and improve the utilization efficiency of the food materials.

[0053] The transmission assembly includes a housing 51, a transmission shaft 52 and a plurality of transmission gears 53. The upper and lower ends of the transmission shaft 52 are respectively connected to the drive motor 4 and the central shaft 411. The outer side of the transmission shaft 52 is provided with a shaft gear 54. The inner side of the transmission disk 421 has a tooth structure corresponding to the transmission gear 53. The transmission gear 53 is respectively connected to the shaft gear 54 and the transmission disk 421. A transmission shaft (not shown in the figure) is provided at the center of the transmission gear 53. The transmission shaft is movably connected to the housing 51. The transmission gear 53 is stationary relative to the circumference of the housing 51 and rotates around the transmission wheel. The shaft gear 54 can drive the transmission plate 421 to rotate around the central rotating shaft 411 through the transmission gear 53. The shaft gear 54 can drive the transmission plate 421 to rotate around the central rotating shaft 411 through the transmission gear 53. When the driving motor 4 rotates the spiral blade 412 in the forward direction through the central rotating shaft 411, the shaft gear 54 also rotates in the forward direction. The transmission gear 53 rotates in the reverse direction under the action of the shaft gear 54. The transmission plate 421 rotates in the reverse direction under the action of the transmission gear 53, thereby causing the outer blade 422 to rotate around the transmission shaft 52 in the reverse direction.

[0054] During operation, the spiral blades 412 and the outer blades 422 rotate in the forward and reverse directions respectively around the transmission shaft 52, so that the food ingredients are subjected to opposite forces at different positions simultaneously, thereby further improving the effect of stirring the food ingredients.

[0055] Preferably, a plurality of transmission gears 53 are evenly distributed along the circumference between the shaft gear 54 and the transmission disk 421, and each transmission gear 53 is respectively connected and cooperated with the shaft gear 54 and the transmission disk 421, so that the force at different positions between the shaft gear 54 and the transmission disk 421 is more uniform, thereby improving the stability of the operation of the transmission disk 421.

[0056] The limiting mechanism includes several first protrusions 61 and second protrusions 62 corresponding to the first protrusions 61. The first protrusions 61 are arranged on the outside of the joint body 3 and extend outward, and the second protrusions 62 are arranged on the outside of the discharge port 21 and extend outward. The horizontal heights of the first protrusions 61 and the second protrusions 62 are staggered with each other. The joint body 3 is screwed to the discharge port 21 so that the vertical positions of the first protrusions 61 and the second protrusions 62 overlap or stagger. When the vertical positions of the first protrusions 61 and the second protrusions 62 overlap, the joint body 3 can be installed and fixed with the discharge port 21 vertically. When the vertical positions of the first protrusions 61 and the second protrusions 62 are staggered, the joint body 3 can be removed from the position of the discharge port 21.

[0057] The upper side of the second protrusion 62 is provided with an upwardly protruding edge 621, the cross-section of the edge 621 is L-shaped, and one side of the edge 621 along the circumferential direction is open. A limiting cavity is formed between the edge 621 and the second protrusion 62, and the first protrusion 61 can enter or leave the limiting cavity through the opening of the edge 621. The edge 621 can limit the position of the first protrusion 61, thereby improving the stability of the installation connection between the joint body 3 and the discharge port 21. Moreover, the edge 621 can also limit the effect of the first protrusion 61 being installed in place. When the joint body 3 is screwed to the discharge port 21, the abutment between the first protrusion 61 and the edge 621 can improve the installation accuracy between the joint body 3 and the discharge port 21.

[0058] A first limiting rib 36 is provided on the joint body 3, and a second limiting rib 11 corresponding to the first limiting rib 36 is provided on the main body 1. When the first protrusion 61 is connected and matched with the second protrusion 62, the first protrusion 61 abuts against the edge 621 along the positive rotation direction, and the first limiting rib 36 abuts against the second limiting rib 11 along the reverse rotation direction. The first limiting rib 36 and the second limiting rib 11 cooperate to limit the relative position of the joint body 3 and the discharge port 21 along the circumferential direction after the joint body 3 and the discharge port 21 are installed in place, further improving the stability of the connection between the joint body 3 and the discharge port 21, and avoiding the accidental falling off of the joint body 3 due to circumferential offset between the joint body 3 and the discharge port 21 during operation.

[0059] A refrigeration assembly for lowering the temperature of the barrel 2 is also provided in the main body 1. The refrigeration assembly includes a compressor 71 and a condenser 72. A refrigeration channel is formed between the barrel 2 and the compressor 71 and the condenser 72. The barrel 2 is cooled by the refrigeration assembly to achieve the effect of making ice cream.
