[0003] This invention relates to the field of cooking machine technology, and in particular to a fruit puree ice cream machine. Background Technology

[0004] As people's living standards improve, their demands for the taste and quality of food are also increasing. Ice cream, as a popular frozen dessert, is constantly evolving in terms of its varieties and production methods. However, traditional ice cream machines often require the addition of large amounts of additives and stabilizers during the production process to ensure the taste and stability of the ice cream. This not only affects the health benefits of ice cream but also limits its flavor diversity to some extent. Summary of the Invention

[0005] To meet consumers' demand for healthy, natural, and diverse flavored ice cream, we have developed a fruit puree ice cream machine. This machine can directly make fruit puree ice cream using fresh fruit, without adding any chemical additives or stabilizers.

[0006] This invention provides a fruit puree ice cream machine, comprising: a housing; a container for holding frozen material, which is detachably connected directly or indirectly to the housing; a main shaft connected to the housing for rotating and extending toward the container; a power assembly, wholly or partially located inside the housing, for driving the main shaft to simultaneously extend and rotate; and a blade connected to the main shaft, which follows the main shaft in extending and rotating to scrape and break up the frozen material in the container layer by layer.

[0007] The power assembly includes a first motor, a second motor, a lifting platform, and a lifting rotor; the first motor is used to drive the main shaft to rotate; the second motor is used to drive the lifting platform to perform lifting; the lifting rotor is rotatably connected to the lifting platform and coaxially connected to the main shaft.

[0008] The advantages of this invention are: simply put fruits, milk, etc. into a container and freeze it in the refrigerator. After freezing, place the container on a fruit puree ice cream machine. When the fruit puree ice cream machine is running, the blades scrape and break up the frozen material layer by layer. The resulting shaved ice has a texture that is similar to ice cream. No chemical additives or stabilizers need to be added. In addition, the equipment is small and suitable for home use and commercial on-site production.

[0009] Furthermore, the power assembly also includes a bushing, which is coaxially sleeved on the main shaft; the bushing is rotatably connected to the housing.

[0010] The first motor drives the bushing to rotate via a first transmission mechanism; the bushing is provided with at least one guide rail extending in the height direction, the guide rail passing through the wall of the bushing in a direction perpendicular to the height direction; the lifting rotor is slidably connected to the bushing in the height direction; and the lifting rotor is provided with a slider that passes through the guide rail and is connected to the main shaft.

[0011] The beneficial effects of adopting the above-mentioned further solution are: the bushing drives the slider to rotate during the rotation process, and the slider drives the main shaft to rotate; and the slider can move up and down along the bushing under the drive of the lifting platform, thereby driving the main shaft to move up and down and rotate on its own. The overall structure is simple and reasonable.

[0012] Furthermore, the first motor drives the main shaft to rotate through a first transmission mechanism; the first transmission mechanism includes a first pulley, a second pulley, and a transmission belt; the first pulley is disposed on the output shaft of the first motor, the second pulley is disposed on the bushing, and the transmission belt is used for transmission between the first pulley and the second pulley.

[0013] The beneficial effects of adopting the above-mentioned further solution are: the first motor drives the first pulley to rotate, the first pulley drives the second pulley to rotate via a transmission belt, the second pulley drives the bushing to rotate, and the bushing drives the lifting rotor and the main shaft to rotate via a slider. The overall structure is simple and reasonable.

[0014] Furthermore, the second motor drives the second lifting platform to perform lifting and lowering through the second transmission mechanism; the second transmission mechanism includes a threaded rod and a nut, the nut is disposed on the lifting platform, the threaded rod is rotatably connected inside the housing and parallel to the main shaft, the second motor drives the threaded rod to rotate, and the threaded rod is threadedly connected to the nut.

[0015] The beneficial effects of adopting the above-mentioned further solution are as follows: the second motor drives the threaded rod to rotate, the threaded rod drives the nut to move up and down, the nut drives the lifting platform to move up and down, the lifting platform drives the lifting rotor to move up and down, and the lifting rotor drives the main shaft to move up and down through the slider. The lifting rotor and the main shaft rotate synchronously. The overall structure is simple and reasonable.

[0016] Furthermore, a guide rod is also provided inside the housing, and the guide rod, threaded rod and main shaft are parallel; the two ends of the lifting platform are slidably connected to the guide rod and the bushing respectively, and the middle part is threadedly connected to the threaded rod through the nut.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the bushing acts as a guide rod, equivalent to connecting guide rods at both ends of the lifting platform and threaded rods in the middle, making the lifting platform run more smoothly. However, the bushing rotates, and the lifting rotor rotates synchronously with it, avoiding wear on the bushing, thus ensuring smooth operation of the lifting platform 43 and a simple and reasonable structure.

[0018] Furthermore, a second inner cavity is provided inside the housing, and a first support member and a second support member are provided inside the second inner cavity; the second support member is fixed to the bottom of the second inner cavity;

[0019] The lower end of the guide rod is fixed to the second support member, and the first support member is fixed to the top of the guide rod; the upper and lower ends of the threaded rod and the bushing are respectively rotatably connected to the first support member and the second support member.

[0020] The advantages of adopting the above-mentioned further solution are: using the first support and the second support to connect the guide rod, the threaded rod and the bushing makes the overall structure more stable and makes assembly, disassembly of the housing and other work more convenient.

[0021] Furthermore, the second support member is fixed to the bottom of the second inner cavity, and a transmission cavity is formed between the two; the transmission mechanism is located inside the transmission cavity.

[0022] The advantages of adopting the above-mentioned further solution are: the sealed transmission cavity prevents the lubricating oil of the first transmission mechanism from leaking out. Furthermore, the second support member serves as both a support and a cover for the transmission cavity, resulting in a simple and reasonable overall structure that is easy to assemble.

[0023] Furthermore, the housing includes a base, a support, and a chassis; the support and the container are arranged side by side on the base, the chassis is fixed on the support, and the container is disposed below the chassis;

[0024] The support portion has a first inner cavity, and the chassis has a second inner cavity, with the first inner cavity and the second inner cavity communicating with each other; at least a portion of the first motor is disposed within the first inner cavity.

[0025] The beneficial effects of adopting the above-mentioned further solution are as follows: The first motor is used to drive the main shaft to rotate. In operation, the main shaft usually needs to rotate at high speed and with large torque, so the first motor is usually relatively heavy. Because the first inner cavity serves as the interior of the support part and is located at a low position, placing the first motor inside the first inner cavity lowers the center of gravity of the equipment, reducing the possibility of tipping over.

[0034] The present invention will be further described below with reference to embodiments. The following examples are used to illustrate this application, but are not intended to limit the scope of this application.

[0035] It should be noted that the terms "top," "bottom," "upper," and "lower" mentioned herein are defined relative to the directions shown in the various accompanying drawings. These are relative concepts and therefore can change depending on their location and usage. Therefore, these or other directions should not be construed as restrictive terms. For example, "upper end" and "lower end" refer to the upper and lower ends of the illustrated device during use, respectively. Furthermore, the term "comprising" does not exclude other elements or steps, and "a" or "an" does not exclude a plural.

[0036] As shown in Figures 1 to 8, the height direction Z is illustrated. This embodiment discloses a fruit puree ice cream machine, comprising: a housing 1; a container 2 for holding frozen material, which is directly or indirectly detachably connected to the housing 1; a main shaft 3 connected to the housing 1 for rotating and extending into the container 2; a power assembly 4, which is wholly or partially located inside the housing 1 for driving the main shaft 3 to simultaneously extend and rotate; and a blade 5 connected to the main shaft 3 and following the extension and rotation of the main shaft 3 to scrape and break up the frozen material in the container 2 layer by layer.

[0037] The power assembly 4 includes a first motor 41, a second motor 42, a lifting platform 43, and a lifting rotor 44; the first motor 41 is used to drive the main shaft 3 to rotate; the second motor 42 is used to drive the lifting platform 43 to perform lifting; the lifting rotor 44 is rotatably connected to the lifting platform 43 and coaxially connected to the main shaft 3.

[0038] Simply place the fruit, milk, etc., into container 2 and freeze it in the refrigerator. After freezing, place container 2 onto the fruit puree ice cream maker. When the fruit puree ice cream maker is running, the blades 5 scrape and break up the frozen material layer by layer. The resulting slush has a texture similar to ice cream, without the need for any chemical additives or stabilizers. Furthermore, the equipment is small and suitable for home use and commercial on-site production.

[0039] The power assembly 4 also includes a bushing 45, which is coaxially mounted on the main shaft 3. The bushing 45 is rotatably connected to the housing 1. The first motor 41 drives the bushing 45 to rotate via a first transmission mechanism 46. At least one guide rail 451 extending axially (i.e., along the height direction) is provided on the bushing 45. The guide rail 451 penetrates the wall of the bushing 45 radially (i.e., in a direction perpendicular to the height direction Z). The lifting rotor 44 is slidably connected to the bushing 45 in the height direction Z. The lifting rotor 44 is provided with a slider 441 that passes through the guide rail 451 and connects to the main shaft 3. During rotation, the bushing 45 drives the slider 441 to rotate, and the slider 441 drives the main shaft to rotate. The slider 441 can also move up and down along the bushing 45 under the drive of the lifting platform 43, thereby enabling the main shaft 3 to move up, down, and rotate independently. The overall structure is simple and reasonable.

[0040] The first motor 41 drives the main shaft 3 to rotate via a first transmission mechanism 46. The first transmission mechanism 46 includes a first pulley 461, a second pulley 462, and a transmission belt 463. The first pulley 461 is mounted on the output shaft of the first motor 41, the second pulley 462 is mounted on the bushing 45, and the transmission belt 463 is used for transmission between the first pulley 461 and the second pulley 462. The first motor 41 drives the first pulley 461 to rotate, the first pulley 461 drives the second pulley 462 to rotate via the transmission belt 463, the second pulley 462 drives the bushing 45 to rotate, and the bushing 45 drives the lifting rotor 44 and the main shaft 3 to rotate via a slider 441. The overall structure is simple and reasonable.

[0041] The second motor 42 drives the second lifting platform 43 to perform lifting and lowering through the second transmission mechanism 47. The second transmission mechanism 47 includes a threaded rod 471 and a nut 472. The nut 472 is disposed on the lifting platform 43, and the threaded rod 471 is rotatably connected inside the housing 1 and parallel to the main shaft 3. The second motor 42 drives the threaded rod 471 to rotate, and the threaded rod 471 is threadedly connected to the nut 472. The second motor 42 drives the threaded rod 471 to rotate, the threaded rod 471 drives the nut 472 to move up and down, the nut 472 drives the lifting platform 43 to move up and down, the lifting platform 43 drives the lifting rotor 44 to move up and down, and the lifting rotor 44 drives the main shaft 3 to move up and down through the slider 441. The lifting rotor 44 rotates synchronously with the main shaft 3. The overall structure is simple and reasonable.

[0042] The housing 1 also includes a guide rod 48, which is parallel to the main shaft 3 and the threaded rod 471. The lifting platform 43 is slidably connected at both ends to the guide rod 48 and the bushing 45, respectively, and its middle portion is threadedly connected to the threaded rod 471 via a nut 472. The bushing 45 acts as a guide rod, essentially connecting the two ends of the lifting platform 43 to the guide rod and the middle portion to the threaded rod 471, making the lifting platform 43 run more smoothly. However, the bushing 45 rotates synchronously with the lifting rotor 44, preventing wear on the bushing 45 and ensuring smooth operation of the lifting platform 43. The structure is simple and reasonable.

[0043] The housing 1 has a second inner cavity 132, and the second inner cavity 132 has a first support member 15 and a second support member 16; the second support member 16 is fixed to the bottom of the second inner cavity 132.

[0044] The lower end of the guide rod 48 is fixed to the second support member 16, and the first support member 15 is fixed to the top of the guide rod 48; the upper and lower ends of the threaded rod 471 and the bushing 45 are respectively rotatably connected to the first support member 15 and the second support member 16. Using the first support member 15 and the second support member 16 to connect the guide rod 48, the threaded rod 471, and the bushing 45 makes the overall structure more stable and facilitates assembly and disassembly of the housing 1.

[0045] The second support member 16 is fixed to the bottom of the second inner cavity 132, forming a transmission cavity 161 between them; the first transmission mechanism 46 is located inside the transmission cavity 161. The sealed transmission cavity 161 prevents the lubricating oil of the first transmission mechanism 46 from leaking out. Furthermore, the second support member 16 serves as both a support member and a cover for the transmission cavity, resulting in a simple and reasonable overall structure that is easy to assemble.

[0046] The housing 1 includes a base 11, a support 12, and a chassis 13; the support 12 and the container 2 are arranged side by side on the base 11, the chassis 13 is fixed on the support 12, and the container 2 is located below the chassis 13.

[0047] The support portion 12 has a first inner cavity 121 inside, and the chassis 13 has a second inner cavity 132 inside, and the first inner cavity 121 and the second inner cavity 132 are connected; at least a portion of the first motor 41 is disposed in the first inner cavity 121.

[0048] The first motor 41 is used to drive the main shaft 3 to rotate. In operation, the main shaft 3 usually needs to rotate at high speed and with large torque, so the first motor 41 is usually heavy. Because the first inner cavity 121 serves as the interior of the support part 12 and is located at a low position, placing the first motor 41 inside the first inner cavity 121 lowers the center of gravity of the equipment and reduces the possibility of tipping over.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
