A food processor 1 according to an embodiment of the invention is described below with reference to fig. 1-2.

As shown in fig. 1-2, the food processor 1 according to the embodiment of the present invention includes a housing 10 and a knife tackle assembly. Cooking chamber 101 and motor chamber 103 are injectd in the casing 10, and cooking chamber 101 separates through baffle 102 with motor chamber 103, is equipped with pilot hole 1021 on the baffle 102. The knife shaft assembly 20 is vertically matched in the assembling hole 1021, two ends of the knife shaft assembly 20 respectively extend into the food processing cavity 101 and the motor cavity 103, the knife shaft assembly 20 comprises an inner knife shaft 201, an outer knife shaft 202, an installation frame 203 and a knife group end cover 204, the outer knife shaft 202 is sleeved on the inner knife shaft 201, the installation frame 203 is connected with the outer knife shaft 202, the installation frame 203 is provided with an end portion 2031 and a peripheral portion 2032, a central hole 20311 is formed in the end portion 2031, the peripheral portion 2032 extends downwards along the periphery of the end portion 2031 to form a cylindrical shape, the top of the inner knife shaft 201 penetrates out of the central hole 20311, the top end of the outer knife shaft 202 extends into the installation frame 203, a first sealing element 208 is arranged between the end surface of the top end of the outer knife shaft 202 and the end portion 2031, the knife group end cover 204 penetrates through the outer knife shaft 202, a second sealing element 209 is arranged between the lower end of the knife group end cover.

Firstly, it should be noted that the food processor 1 in the present invention may be a soymilk machine, a blender, or a wall breaking machine, and the specific form of the food processor 1 is not limited herein. Meanwhile, the knife shaft assembly 20 of the food processor 1 of the present invention is generally vertically disposed, but the possibility of the knife shaft assembly 20 being laterally disposed is not excluded, and when the knife shaft assembly 20 is laterally disposed, the up-down positional relationship in the following description is adjusted correspondingly, and the structure of the whole knife shaft assembly 20 is not affected.

It can be understood that, because the outer cutter shaft 202 is sleeved on the inner cutter shaft 201, in the actual use process, although the inner cutter shaft 201 and the outer cutter shaft 202 rotate coaxially, the inner cutter shaft 201 and the outer cutter shaft 202 can rotate in the same direction, in the opposite direction and at different rotation speed ratios by externally connecting different power output sources. Through different speed ratios and rotation directions, the stirring and crushing capabilities of the food processor 1 can be greatly improved, the fineness of food or medicinal materials can be improved, and the use experience of a user is improved.

It can be understood that, since the mounting bracket 203 has a peripheral portion 2032 and an end portion 2031 sleeved on the top end of the outer cutter shaft 202, the end portion 2031 has a fitting hole 1021 passing through the inner cutter shaft 201, and the inner cutter shaft 201 passes through the outer cutter shaft 202. The place where the top end of the outer cutter shaft 202 contacts with the inner cutter shaft 201 is covered on the mounting frame 203. Therefore, the phenomenon that liquid flows to the motor cavity 103 from the gap between the inner cutter shaft 201 and the outer cutter shaft 202 is avoided to a certain extent. Meanwhile, a first sealing element 208 is arranged between the end face of the top end of the outer cutter shaft 202 and the end 2031 of the mounting frame 203, so that the sealing effect between the inner cutter shaft 201 and the outer cutter shaft 202 is better ensured, and the phenomenon of water inflow of the motor cavity 103 is better prevented.

It should be added that, because the second sealing element 209 is arranged between the lower end of the knife tackle end cover 204 and the partition plate 102, the possibility that liquid flows into the motor cavity 103 from the gap between the knife tackle end cover 204 and the partition plate 102 is reduced, and therefore the phenomenon that water enters the motor cavity 103 is well prevented. In addition, as the cutter group end cover 204 is arranged on the outer cutter shaft 202 in a penetrating manner, and the third sealing element 210 is arranged between the cutter group end cover 204 and the outer cutter shaft 202, the liquid is reduced to flow into the cutter group end cover 204 from a gap between the cutter group end cover 204 and the outer cutter shaft 202, and the phenomenon of water accumulation inside the cutter group end cover 204 is well avoided.

In summary, in the food processor 1 according to the embodiment of the present invention, the mounting bracket 203 sleeved on the top of the outer knife shaft 202, the first sealing member 208 disposed between the end surface of the top end of the outer knife shaft 202 and the end 2031 of the mounting bracket 203, the second sealing member 209 disposed between the lower end of the knife group end cover 204 and the partition plate 102, and the third sealing member 210 disposed between the knife group end cover 204 and the outer knife shaft 202 better ensure the sealing between the knife shaft assembly 20 itself and the partition plate 102.
