[0036] Referring to Figures 1-10 A food processor includes a container 10, a head element 20, a cutter element 30, and a drive module 40, the container 10 is formed with a container cavity 100;

[0037] The drive module 40 is arranged in the head element 20, and the drive module 40 includes a mounting platform 400;

[0038] A moving shaft 420 is arranged on the mounting platform 400 and rotates relative to the mounting platform 400 along a first direction X, and the moving shaft 420 is connected with the cutter element 30;

[0039] A transmission shaft 430 is rotatably arranged on the mounting platform 400;

[0040] The transmission shaft 430 is in driving connection with the moving shaft 420, and when the transmission shaft 430 rotates, the moving shaft 420 is driven to rotate;

[0041] The moving shaft 420 is provided with a driven wheel 470, the driven wheel 470 is provided with an annular track groove 471, the transmission shaft 430 is provided with an inclined driving wheel 460, and the inclined driving wheel 460 is at least partially movably inserted into the annular track groove 471;

[0042] The tilt driving wheel 460 is gradually tilted in the second direction S, and when the tilt driving wheel 460 rotates, the tilt driving wheel 460 can drive the tilt driving wheel 460 and the transmission shaft 430 to reciprocate along the first direction X between the first position and the second position;

[0043] The rotation module 50 is arranged on the mounting platform 400 and is in transmission connection with the transmission shaft 430.

[0044] The working principle of the food processor is that the rotation module 50 drives the transmission shaft 430 to rotate, and the tilt driving wheel 460 and the moving shaft 420 are driven to rotate by the transmission shaft 430.

[0045] The moving shaft 420 rotates to drive the cutter element 30 to rotate. Figure 10 At the same time, under the action of the tilt driving wheel 460, the tilt driving wheel 460 can move in the annular track groove 471, and the tilt driving wheel 460 can drive the annular track groove 471 to move downward or upward.

[0046] In the utility model, the tilt driving wheel 460 rotates one circle to complete a complete cooking process, and the process is divided into a descending cooking stroke of the cutter element 30 and an ascending retreat stroke of the cutter element 30.

[0047] The descending cooking stroke is that the moving shaft 420 drives the cutter element 30 to move downward and rotate to process and cook materials in the cavity 100.

[0048] The ascending retreat stroke is that the moving shaft 420 drives the cutter element 30 to move upward and rotate to retreat the cutter element 30 upward.

[0049] In the utility model, the second direction S and the first direction X are perpendicular to each other.

[0050] As shown in Figure 6 and Figure 8As shown, the rotating module 50 comprises a driving motor 510 arranged on the mounting platform 400, the driving motor 510 is provided with a first gear 520, the transmission shaft 430 is provided with a second gear 540, the first gear 520 and the second gear 540 are in transmission connection. In this embodiment, the driving motor 510 and the transmission shaft 430 are in gear transmission, in addition, the driving motor 510 and the transmission shaft 430 can be in synchronous wheel and synchronous belt transmission.

[0051] As shown in Figure 6 and Figure 8 , a third gear 530 is arranged between the first gear 520 and the second gear 540, the first gear 520, the third gear 530 and the second gear 540 are in meshing in turn, completing the transmission connection and realizing power transmission. The advantage of gear transmission is that the transmission ratio is accurate and there is no problem such as slipping, improving the stability of transmission.

[0052] Referring to Figure 5 , the mounting platform 400 is provided with a main shaft 410, the moving shaft 420 is hollow inside to form a shaft cavity 421 with an opening, the main shaft 410 is movably inserted into the shaft cavity 421, and the moving shaft 420 is arranged to reciprocate relative to the main shaft 410 along the first direction X. The main shaft 410 is used to provide stable guidance for the moving shaft 420 to ensure the moving stability and rotating stability of the moving shaft 420.

[0053] As shown in Figure 5 , the main shaft 410 is rotatably arranged on the mounting platform 400. The rotatably arranged main shaft 410 can reduce friction, especially when the moving shaft 420 rotates, the main shaft 410 can rotate synchronously to avoid wear. Of course, the main shaft 410 can also be fixedly arranged, and when it is fixedly arranged, the moving shaft 420 moves up and down relative to the main shaft 410 and rotates.

[0054] As shown in Figure 5 , the moving shaft 420 is rotatably arranged relative to the main shaft 410. The purpose of this rotatable arrangement is that when the main shaft 420 is fixedly arranged, the moving shaft 420 must be rotatably arranged relative to the main shaft 410. However, when the main shaft 410 is rotatably arranged, the moving shaft 420 can or can not rotate. However, the advantage of rotatable arrangement is that when the moving shaft 420 rotates, the moving shaft 420 can rotate relative to the main shaft 410 to avoid the main shaft 410 being stuck and unable to rotate, thereby affecting the rotation of the moving shaft 420.

Since the first direction X is the up-down direction, the moving shaft 420 moves from the first position to the second position from top to bottom, and from the second position to the first position from bottom to top. The force of the first elastic element 480 is to ensure that the moving shaft 420 can move from the second position to the first position along the first direction X, avoiding the failure of the moving shaft 420 to reset.

[0058] As shown in Figure 5 The mounting platform 400 is provided with a through hole 401 that penetrates up and down, and the moving shaft 420 moves in the through hole 401.

[0062] As shown in Figure 3As shown, the telescopic chopping board module 60 comprises a chopping board body 610 which is arranged in the cavity 100 and reciprocally moves along the first direction X relative to the cavity 100; a second elastic element 650 is arranged between the chopping board body 610 and the container 10 for pushing the chopping board body 610 to reset.

[0063] As shown, Figure 3 the chopping board body 610 is provided with a plurality of guide posts 630 which are arranged to extend along the first direction X, the container 10 is provided with guide holes 140 which correspond to the positions of the guide posts 630, the guide posts 630 are arranged to pass through the guide holes 140, and the second elastic element 650 is sleeved on the guide posts 630, one end of the second elastic element 650 is connected with the chopping board body 610, and the other end is connected with the container 10.

[0066] As shown, Figure 3 the hole wall of the mounting hole 110 is provided with a sealing ring 120 which is in abutment with the outer wall of the chopping board body 610.

[0067] As shown, Figure 3 the chopping board body 610 is provided with a limiting portion 620 which is in abutment with the bottom wall of the container 10 to restrict the upward movement of the chopping board body 610 to avoid disengaging from the mounting hole 110.

[0068] As shown, Figure 3 the plurality of guide posts 630 are collectively connected with a connecting seat 660, and the chopping board body 610 is fixedly connected with the connecting seat 660.

[0069] As shown, Figure 3 the upper surface of the chopping board body 610 is a concave surface which is gradually recessed from the outer side to the inner side, the concave surface forms a concave cavity 611 for positioning materials, the cutter element 30 is arranged above the chopping board body 610, and the first direction X is the up-down direction.
