Referring to fig. 1 to 9, an embodiment of the present application provides a machine head of a food processor, the machine head 100 includes a surface cover 110 and a lower cover 120 having an opening at one end, the lower cover 120 includes a housing and a first surrounding rib 122, the surface cover 110 is fastened at the opening end of the lower cover 120, and the first surrounding rib 122 is connected inside the housing to form a blocking compartment 123 with the housing. The blocking compartment 123 is configured to block wash water or a majority of water vapor entering the interior of the handpiece 100 from the blocking compartment 123 to prevent electrical components, such as the motor 180 or the circuit board 150, within the handpiece 100 from becoming wet or wet.

The handpiece 100 comprises a face cover 110 and a lower cover 120, the upper end of the lower cover 120 is open, the face cover 110 is buckled at the open end of the lower cover 120, and the face cover 110 and the lower cover 120 can be connected in a connecting mode such as connecting piece connection, buckle clamping and the like.

The first surrounding rib 122 is connected to the housing of the lower cover 120, and the first surrounding rib 122 and the housing form a blocking compartment 123 for storing water vapor (water vapor or washing water) entering the lower cover 120, so as to play a role of buffering and blocking, so as to prevent the water vapor or the washing water from entering the interior of the handpiece 100 and causing the failure of the motor 180 or the circuit board 150. Therefore, due to the arrangement of the separation blocking cavity 123, even if the surface cover 110 and the lower cover 120 are connected from bottom to top through screws and the screws are located at the mouth of the cup body 200 of the food processor as in the prior art, the influence of water vapor on the motor 180 or the circuit board 150 can be avoided. The cross section of the first surrounding rib 122 may be a straight line, an L-shape, an S-shape, or any other shape that can form a blocking compartment 123 with the housing. The first circumferential rib 122 may be connected to the first mounting portion 124, the second mounting portion 125 (see fig. 2), or between the first mounting portion 124 and the second mounting portion 125, or may be connected to another position of the housing, and the shape of the first circumferential rib 122 and the position of connection to the housing may be determined according to the position of the joint between the face cover 110 and the lower cover 120.

In some embodiments, the face cover 110 includes a cover plate 111 and a first flange 113 disposed along a periphery of the cover plate 111 and facing the lower cover 120, the housing includes a first mounting portion 124 and a second bead 121 connected to the first mounting portion 124, an end of the second bead 121 away from the first mounting portion 124 forms an open end of the lower cover 120, an upper end of the second bead 121 forms a step-shaped abutting portion 1211, and the first flange 113 is engaged with the abutting portion 1211.

The stepped abutting portion 1211 has an L-shape, and a side surface of the L-shaped abutting portion 1211 may abut against an inner side and/or an outer side of the first flange 113. The engagement of the abutting portion 1211 with the first flange 113 can further reduce the water vapor entering the handpiece 100 through the gap between the face cover 110 and the lower cover 120 and increase the path of the water vapor entering the interior of the handpiece, thereby increasing the condensation time of the water vapor before the water vapor passes through the blocking compartment 123 so that the condensed water falls into the blocking compartment 123.

Referring to fig. 3 and 4, the second bead 121 has an abutting portion 1211 at an upper end thereof, and the first flange 113 is engaged with an outer portion of the abutting portion 1211.

The present embodiment provides a food processor, referring to fig. 10, the food processor includes a cup body 200 and the head provided in any of the above embodiments, and the head 100 is buckled on the cup body 200. In the food processor of the present application, the inside separation chamber 123 of the head is provided to block the washing water or most of the water vapor entering the inside of the head 100 in the separation chamber 123, so as to prevent the electric components such as the motor 180 or the circuit board 150 inside the head 100 from being affected with damp or stained with water.

The food processor comprises but is not limited to a soybean milk machine, a juice extractor or a wall breaking machine.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and all the changes or substitutions should be covered by the scope of the present application. Moreover, the technical solutions in the embodiments of the present application may be combined with each other, but it is necessary that a person skilled in the art can realize the combination as a basis, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent, and is not within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
