[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1 As shown, a food processor with an improved circuit board 4 assembly is characterized by comprising a main unit base 1, a dual-shaft motor 2, a centrifugal impeller 3, a circuit board 4, a heat sink 5, and a bottom cover 6.

[0022] The main unit base 1 has an upper opening and includes a cover cavity 11, a front insertion hole 12, a base frame 13, a motor cavity 14, an upper volute 15, and an air outlet cavity 16. The motor cavity 14 and the upper volute 15 are arranged vertically, and the upper volute 15 is located on the top plate of the air outlet cavity 16. The air outlet cavity 16 has a rear opening.

[0023] The bottom cover plate 6 includes an air inlet cavity 61 with a lower opening, an air guide support cavity 62, a lower half volute 63 and a rear back plate 64, and an air outlet hole group is provided on the rear back plate 64.

[0024] Circuit board 4 and heat sink 5 are fixed, heat sink 5 is inserted into base frame 13, and circuit board 4 extends from the front of base frame 13; dual-shaft extension motor 2 is fixed to the top of motor cavity 14, and there is a gap between dual-shaft extension motor 2 and motor cavity 14; centrifugal impeller 3 is fixed to the lower shaft extension of dual-shaft extension motor 2; bottom cover plate 6 is fitted into cover plate cavity 11; air inlet cavity 61 extends into main unit base 1 through front insertion hole 12; air guide support cavity 62 supports heat sink 5; upper half volute 15 and lower half volute are fastened together to form volute; centrifugal impeller 3 is located in volute; rear back plate 64 is fitted into the rear opening of air outlet cavity 16.

[0025] The large height of the air inlet cavity 61 prevents water from entering the support surface. During use, indoor air enters the main unit through the air inlet cavity 61, the air guide support cavity 62, and the radiator 5. Then, it enters the volute through the gap between the dual-shaft extension motor 2 and the motor cavity 14, and finally flows out through the air outlet group.

[0026] As a further improvement to this utility model: such as Figure 2 As shown, the top and bottom plates of the air guide support cavity 62 are respectively provided with top air inlets and bottom air inlets, which are staggered. This structure prevents foreign objects from entering the main unit.
