The cutting barrel 12 is installed above the juicing cup 11 and is provided with a cutting knife 14 which rotates coaxially with the screw 13. The user can directly put the food into the cutting barrel 12, and the cutting knife 14 in the cutting barrel 12 cuts the food into small pieces, which then fall into the juicing cup 11 and are squeezed out of juice by the screw 13. A cover 15 is also provided on the top of the cutting barrel 12 to prevent foreign matter from entering the cutting barrel 12 during operation.

[0027] The safety switch 4 includes a push rod 41 and a micro switch 42. An electric control bracket 6 for installing an electric control board 5 is provided in the base 2. The micro switch 42 is connected and arranged on the upper part of the electric control board 5. A connection seat 62 is provided on the top of the electric control bracket 6 for the push rod 41 to movably pass through. The upper and lower parts of the push rod 41 both pass through the connection seat 62, and a spring 8 is sleeved in the middle part to act on the inside of the connection seat 62 so that the push rod 41 can elastically move up and down. The upper part 411 of the push rod passes through the base 2 and contacts the trigger mechanism 3 of the juice extraction component 1. When the juice extraction component 1 is installed on the top of the base 2, the push rod 41 is pushed downward by the trigger mechanism 3, and the lower part 412 of the push rod triggers the micro switch 42 to connect, and the electric control board 5 controls the motor 7 to be energized and ready to work.

[0028] The trigger mechanism 3 includes a lower pressing shaft mechanism 31 that penetrates the juicing component 1 axially and is arranged on the side. The cover body 15 is also provided with a pressing portion that presses the lower pressing shaft mechanism 31 downward to contact the upper portion 411 of the push rod on the top of the base 2 when the juicing component 1 is covered. When the juicing component 1 is installed on the base 2, it is also necessary to ensure that the base 2 is powered on to start the motor 7 to drive the screw 13 to perform juicing work only after the cover body 15 is covered, so as to avoid safety problems caused by human hands reaching into the barrel.

[0029] A positioning column 61 extends from the side of the electric control bracket 6 and passes through the electric control board 5. The micro switch 42 is provided with a positioning hole 421 sleeved on the positioning column 61. The micro switch 42 is positioned and installed by the positioning column 61, and the micro switch 42 is supported and supported, so as to reduce the weight borne by the electric control board 5 after the micro switch 42 is installed on the electric control board 5. A mounting cavity 63 for mounting the electric control board 5 is formed on the side of the electric control bracket 6. The insertion seat 62 is located above the mounting cavity 63. Through the mounting cavity 63, the micro switch 42 and the electric control board 5 are both located below the insertion seat 62, so that the micro switch 42 and the push rod 41 on the insertion seat 62 can be triggered in cooperation. A screw connection column 64 for fixing the electric control board 5 is formed on the wall of the mounting cavity 63, and the positioning column 61 is also arranged on the wall of the mounting cavity 63.

[0030] A plurality of mounting posts 21 for mounting the electric control bracket 6 are provided in the machine base 2, and a plurality of mounting sleeves 65 for inserting the mounting posts 21 are correspondingly provided on the electric control bracket 6. Specifically, the mounting posts 21 include three extending downward from the top of the inner cavity of the machine base 2, wherein two mounting posts are arranged in parallel and a through hole 23 for the upper part 411 of the push rod to pass through is provided between the two mounting posts, the through-connection seat 62 is provided between the two mounting sleeves 65, another mounting post is provided with a screw hole inserted into another mounting sleeve 65, and the mounting posts 21 and the mounting sleeve 65 are fixed by through-connection screws, so that the electric control bracket 6 is hoisted in the machine base 2, which is beneficial to the waterproof arrangement of the electric control bracket 6.

[0031] A sinking cavity 22 is provided at the position where the upper portion 411 of the pushing rod passes through the top of the machine base 2. The upper portion 411 of the pushing rod passes into the sinking cavity 22. The trigger mechanism 3 of the juice extraction component 1 needs to move down into the sinking cavity 22 to contact the pushing rod 41. The setting of the sinking cavity 22 is, on the one hand, to protect the pushing rod 41, and on the other hand, when the lower pressing shaft mechanism 31 of the trigger mechanism 3 is stuck in the sinking cavity 22, it has a certain positioning effect on the juice extraction component 1.

[0032] In order to achieve a waterproof setting at the outlet of the push rod 41, a sealing ring 66 is installed on the top of the joint seat 62. The electric control bracket 6 and the machine base 2 are fixedly installed so that the sealing ring 66 is clamped between the joint seat 62 and the top wall of the inner cavity of the machine base 2. The upper part 411 of the push rod passes through the sealing ring 66 and out to the top of the machine base 2, effectively achieving a waterproof setting at the joint.

[0033] When the lower portion 412 of the push rod moves downward, the micro switch 2 is triggered by applying force on one side; and the connecting seat 62 extends downward to have a retaining wall 67 arranged on the other side opposite to the lower portion 412 of the push rod to support the lower portion 412 of the push rod, so that the micro switch 2 can be accurately triggered each time the lower portion 412 of the push rod moves downward.

[0034] The utility model realizes the setting of the safety switch 4 at the same time by installing the electric control bracket 6 of the electric control board 5. The micro switch 42 of the safety switch 4 is directly connected and arranged on the electric control board 5. The electric control bracket 6 is also arranged with a through-connection seat 61 for movably installing the push rod 41 that triggers the micro switch 42. The above arrangement can save the lead connection of the safety switch 4, simplify the layout in the base 2, and at the same time, the electric control bracket 6 on which the electric control board 5 is installed is used to set the safety switch 4, without setting a structure for installing the safety switch 4 in another place of the base 2, thereby simplifying the structure of the base 2.
