[0006] A body, wherein a receiving cavity is provided in the body, an inner pot and a heating element are provided in the receiving cavity, and the heating element is located at the lower side of the inner pot;

[0007] a pot cover, which is arranged on the inner pot;

[0008] a drive assembly disposed below the inner pot, the drive assembly comprising a drive motor, a transmission assembly, and a stirrer connecting shaft rotatably and sealedly connected to the inner pot, the output end of the drive motor being connected to the input end of the transmission assembly, the output end of the transmission assembly being connected to the input end of the stirrer connecting shaft, the output end of the stirrer connecting shaft passing upward through the inner pot and extending into the interior of the inner pot; and

[0009] A heat insulation cover is arranged on the lower side of the inner pot, and the heat insulation cover separates the heating element from the driving component.

[0010] A further solution is that a mounting seat is provided on the lower side of the bottom wall of the accommodating cavity, and the driving motor and the transmission assembly are both arranged on the mounting seat; the heating element is located between the bottom wall of the accommodating cavity and the bottom wall of the inner pot;

DETAILED DESCRIPTION

[0038] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 4 As shown, this embodiment provides a new type of paste machine, including:

[0040] A housing 1 is provided with a housing cavity 11, wherein an inner pot 12 and a heating element 13 are provided in the housing cavity 11, and the heating element 13 is located below the inner pot 12;

[0041] A pot cover 9 is provided on the inner pot 12;

[0042] a drive assembly disposed below the inner pot 12, the drive assembly comprising a drive motor 2, a transmission assembly 3, and an agitator connecting shaft 4 rotatably and sealedly connected to the inner pot 12, wherein the output end of the drive motor 2 is connected to the input end of the transmission assembly 3, the output end of the transmission assembly 3 is connected to the input end of the agitator connecting shaft 4, the output end of the agitator connecting shaft 4 passes upward through the inner pot 12 and extends into the interior of the inner pot 12, thereby connecting to the agitator 14 located inside the inner pot 12; and

[0043] The heat insulation cover 5 is provided on the lower side of the inner pot 12 , and the heat insulation cover 5 separates the heating element 13 from the driving assembly.

[0044] A specific implementation is that a mounting seat 6 is provided on the lower side of the bottom wall of the accommodating cavity 11, and the drive motor 2 and the transmission assembly 3 are both arranged on the mounting seat 6, and the mounting seat 6 is configured to be fixedly connected to the bottom wall of the accommodating cavity 11, specifically, it can be fixedly connected by a plurality of screws 8; the heating element 13 is located between the bottom wall of the accommodating cavity 11 and the bottom wall of the inner pot 12; the heating element 13 can be configured to be fixedly connected to the bottom wall of the accommodating cavity 11 through a plurality of heating elements 13, thereby being used to support the inner pot 12.

[0045] To provide better thermal insulation protection for the heat shield 5, a through hole 111 is provided on the bottom wall of the accommodating chamber 11 in this embodiment. The lower end of the heat shield 5 extends downward through the through hole 111. The input end of the agitator connecting shaft 4 and the output end of the transmission assembly 3 are both located on the inner side of the heat shield 5. Thus, the heat shield 5 cooperates with the bottom wall of the accommodating chamber 11 to isolate the heating element 13 from the drive assembly.

[0046] The heating element 13 can be configured as an annular heating plate and arranged around the outer side of the protective cover. Specifically, the annular heating plate has a larger contact area with the bottom of the inner pot 12, so that the food in the inner pot 12 can be heated more evenly.

[0047] In this embodiment, Figure 1 and Figure 2As shown, since the stirrer connecting shaft 4 is sealed with the inner pot 12, it is not convenient to remove it from the inner pot 12. Therefore, when the user needs to take the inner pot 12, the stirrer connecting shaft 4 must be connected to the stirrer connecting shaft 4. To facilitate user operation, the upper end of the heat insulation cover 5 is fixedly connected to the inner pot 12, and the lower end of the heat insulation cover 5 is detachably connected to the mounting seat 6 after passing through the through hole 111 on the bottom wall of the accommodating cavity 11. The input end of the stirrer connecting shaft 4 is detachably connected to the output end of the transmission assembly 3. Since the input end of the stirrer connecting shaft 4 is located on the inner side of the protective cover, when the user removes the inner pot 12, the heat insulation cover 5 can be supported on the table, thereby supporting the inner pot 12 and protecting the stirrer connecting shaft 4 from being hit or dented.

[0048] In this embodiment, Figure 2 and Figure 3 As shown, as a specific structure of the heat shield 5, the heat shield 5 includes an upper top wall 53 fixedly connected to the inner pot 12, an annular side wall 52 extending downward from the circumference of the upper top wall 53, and a shaft seat 51 extending downward from the middle portion of the upper top wall 53. The agitator connecting shaft 4 is rotatably disposed in the shaft seat 51 via a bearing 511, and the agitator connecting shaft 4 is sealedly connected to the heat shield 5 and the inner pot 12. Specifically, the downward extension length of the shaft seat 51 is smaller than the annular side wall 52. The shaft seat 51 is provided with an axial hole extending vertically therethrough. The agitator connecting shaft 4 is inserted into the axial hole, and its lower end is located in the annular side wall 52. Therefore, when the annular side wall 52 is supported on a table, the lower end of the agitator connecting shaft 4 is at a certain distance from the table.

[0049] The upper top wall 53 can be fixedly connected to the inner pot 12 via a plurality of screws 8, and each screw 8 is sealed to the inner pot 12 to prevent liquid leakage. The upper top wall 53 can also be integrally formed with the bottom wall of the inner pot 12.

[0050] In this embodiment, Figures 2 to 4 As shown in the figure, as a specific embodiment in which the heat shield 5 and the mounting base 6 are detachable, the mounting base 6 is provided with an annular slot 61 on the upper side, and the lower end of the annular side wall 52 is inserted downwardly into the annular slot 61. In other words, the heat shield 5 can be separated from the mounting base 6 by lifting the inner pot 12 upward, making it convenient for the user to remove and place the inner pot 12.

[0051] Among them, the transmission assembly 3 includes a worm 31 connected to the output shaft of the drive motor 2, a worm wheel 32 connected to the worm 31, and a transmission base 33 coaxially arranged on the upper side of the worm wheel 32, and the worm wheel 32 rotates synchronously with the transmission base 33; a plurality of vertical grooves 331 with notches all facing upward are provided around the transmission base 33, and the lower end of the agitator connecting shaft 4 is provided with a horizontal swing arm 41 inserted into the vertical groove 331, and the horizontal swing arm 41 is fixedly connected to the lower end of the agitator connecting shaft 4. The horizontal swing arm 41 can be disengaged from the vertical groove 331 upward by lifting the inner pot 12 upward; when the drive motor 2 drives the transmission base 33 to rotate through the worm 31 and the worm wheel 32, the side wall of the vertical groove 331 drives the agitator connecting shaft 4 to rotate by abutting against the horizontal swing arm 41, thereby driving the agitator 14 to rotate.

[0052] In this embodiment, Figures 2 to 4 As shown, in order to prevent the stirrer 14 from causing the inner pot 12 to rotate relative to the machine body 1 when encountering large resistance, at least one limit block 521 is provided around the annular side wall 52, and a limit groove 611 corresponding to the limit block 521 is provided on the side wall surrounding the annular slot 61. The limit block 521 is inserted into the limit groove 611 to circumferentially fix the heat shield 5 to the mounting seat 6. Specifically, there are four limit blocks 521, which are evenly spaced and arranged on the inner side of the annular side wall 52. There are four limit grooves 611, which are arranged on the inner side wall of the annular slot 61. The four limit blocks 521 are inserted into the four limit grooves 611, thereby preventing the heat shield 5 from rotating relative to the mounting seat 6, thereby preventing the inner pot 12 from rotating relative to the machine body 1.

[0053] In this embodiment, Figure 2 As shown, the stirrer connecting shaft 4 is sealedly connected to the heat shield 5 and the inner pot 12 via a seal 7. The seal 7 includes a first sealing portion located between the stirrer connecting shaft 4 and the inner pot 12 and a second sealing portion located between the stirrer connecting shaft 4 and the shaft seat 51. The first and second sealing portions are both annular, and the upper end of the shaft seat 51 is provided with a mounting groove that cooperates with the second sealing portion.

[0054] Working principle description:

[0055] When the porridge maker is in operation, the drive motor 2 rotates the agitator connecting shaft 4 through the transmission assembly 3, which in turn drives the agitator 14 to rotate, mashing the potatoes or sweet potatoes cooked in the inner pot 12 into a paste. The protective cover isolates the heating element 13 from the agitator connecting shaft 4 and the transmission assembly 3, thereby reducing the impact of heat radiation generated by the heating element 13. When the inner pot 12 needs to be removed for cleaning, the inner pot 12 is simply lifted upward, disengaging the horizontal swing arm 41 from the longitudinal groove and simultaneously disengaging the protective cover from the mounting base 6. When the inner pot 12 is placed on a table, the lower end of the protective cover is supported on the table.

[0056] The present invention is not limited to the above optional implementation methods. Under the premise of not conflicting with each other, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the scope of protection of the present invention.
