fig. 7 is a structural view of a section B-B in fig. 6. As shown in fig. 1 to 7, the shielding assembly 2 includes at least one blocking structure 21, and the blocking structure 21 is movably connected to the transmission mechanism 1. The blocking structure 21 includes a blocking portion 211 and a force receiving portion 213 connected to the blocking portion 211, the transmission mechanism 1 includes a cover 11, and the cover 11 is provided with a cutter shaft assembling hole 111. The force receiving portion 213 is forced to move the blocking portion 211 between the second position and the first position engaged with the arbor shaft assembly hole 111.

Through the movable connection of the blocking structure 21 and the transmission mechanism 1, the force-bearing part 213 of the blocking structure 21 is forced to drive the blocking part 211 to move between the second position and the first position matched with the cutter shaft assembly hole 111, when the blocking part 211 is at the first position, the blocking part 211 covers at least a part of the cutter shaft assembly hole 111, the cutter shaft 15 can be prevented from passing through the cutter shaft assembly hole 111, and when the blocking part 211 is at the second position, the cutter shaft 15 can pass through the cutter shaft assembly hole 111 to be matched with the output shaft 13 to realize transmission.

It should be noted that the shielding assembly 2 may include one, two or more baffle structures 21, which is not limited in this application. As shown in fig. 1, 3, 4 and 6, when the protection assembly 2 includes two blocking structures 21, the blocking portions 211 of the two blocking structures 21 cooperate to cover the arbor shaft assembling hole 111. For example, when the knife shaft assembling hole 111 is a circular hole, the blocking part 211 may be a semicircular plate-shaped structure, and each blocking part 211 is engaged with or separated from the half knife shaft assembling hole 111, so that the space occupation of the blocking structure 21 on the food processor 5 in the moving process can be reduced, and the structural stability of the protection assembly 2 can be improved. Alternatively, the blocking portion 211 may have another structure matching at least a part of the structure of the arbor shaft assembling hole 111, which is not limited in the present application. The structure and arrangement of the shielding assembly 2 is exemplified below with the shielding assembly 2 comprising two barrier structures 21:

The blocking structure 21 is drivingly connected to the cover 11 such that the blocking structure 21 is movable relative to the cover 11 to facilitate movement of the blocking portion 211 between the first position and the second position. It should be noted that the connection portion 212 and the matching portion 112 may be in transmission connection through a rotation connection, a sliding connection, and the like, and the application is not limited thereto. When the connecting portion 212 is rotatably connected to the mating portion 112, the blocking structure 21 may be rotated or flipped relative to the end surface of the arbor shaft assembly hole 111 to achieve the movement of the blocking portion 211 between the first position and the second position, which is not limited in the present application.

In an embodiment, the blocking structure 21 may be rotatably connected to the cover 11, and the blocking structure 21 may rotate relative to the end surface of the cutter shaft assembling hole 111, for example, the above-mentioned rotation fit relationship can improve the motion reliability and the structural installation convenience of the blocking structure 21. For example, the cover 11 may define an accommodating space, the engaging portion 112 may be a rotating pillar disposed in the accommodating space, and the connecting portion 212 may be a cylindrical hole disposed on the blocking structure 21, and the cylindrical hole is sleeved on the rotating pillar and can rotate relative to the rotating pillar. When the shielding assembly 2 comprises two barrier structures 21, the cover 11 may be correspondingly provided with two rotation posts. The rotation column can be disposed at an edge of the accommodating space to provide a sufficient stroke space for the engagement and disengagement of the blocking portion 211 and the cutter shaft assembling hole 111, and to avoid the interference between the blocking structure 21 and other structures of the cover 11.

In the above embodiment, the force-receiving portion 213 and the blocking portion 211 may be disposed on two sides of the connecting portion 212 to improve the rotation flexibility and stability of the blocking structure 21 and reduce the space occupation of the blocking structure 21 during the rotation process.

In some embodiments, the shielding assembly 2 may further include an elastic restoring member 22, and the cover 11 and the blocking structure 21 are elastically abutted to the elastic restoring member 22 respectively. The elastic reset piece 22 is respectively elastically abutted with the cover body 11 and the blocking structure 21, so that the blocking part 211 of the blocking structure 21 can reciprocate between the first position and the second position, and the structure is simple and reliable. Wherein, elasticity piece 22 that resets can be the torsional spring, the one end and the lid 11 butt of torsional spring, the other end of torsional spring with separate fender structure 21 butt, when keeping off the atress of the atress portion 213 of structure 21 and take place the motion after, the torsional spring produces compression deformation, and the torsional spring resumes deformation and makes to separate fender structure 21 and reset after the power cancellation that is used for atress portion 213.

In one embodiment. The elastic restoring element 22 can be assembled on the connecting portion 212 of the blocking structure 21, so that the elastic restoring element 22 is respectively matched with the blocking structure 21 and the cover 11 in an abutting manner, and meanwhile, the space occupation of the elastic restoring element 22 is reduced. Taking the elastic restoring element 22 as a torsion spring, when the engaging portion 112 is a rotating column disposed in the accommodating space and the connecting portion 212 is a cylindrical hole disposed on the blocking structure 21, the torsion spring can be fixedly assembled outside the cylindrical hole by a screw 23. The accommodation space of the cover 11 may further be provided with a limit fitting member 113, the stress portion 213 penetrates through the limit hole 1131 of the limit fitting member 113, one end of the torsion spring may abut against the limit fitting member 113, and the other end of the torsion spring abuts against the blocking structure 21.

Food processor 5 includes host computer 4 and cup 3, and protection component 2 assembles in host computer 4, and cup 3 is equipped with butt piece 311, and when host computer 4 assembled in cup 3, butt piece 311 and inclined matching surface 2131 slip butt. The baffle structure 21 is pushed by the sliding contact between the inclined matching surface 2131 of the force bearing part 213 and the contact part 311 on the cup body 3, so that the structure is flexible and reliable.

In one embodiment, as shown in fig. 5 and 7, the force receiving portion 213 may include at least two inclined mating surfaces 2131, and each inclined mating surface 2131 is connected in sequence. The opening speed of the baffle structure 21 is changed by the cooperation of the at least two inclined mating surfaces 2131 and the abutting pieces 311, so that the baffle structure 21 can realize corresponding functions in different movement speed sections. For example, the force receiving portion 213 may include two inclined engagement surfaces 2131, and when the main body 4 is assembled to the cup body 3, the abutting members 311 respectively slidably abut against the two inclined engagement surfaces 2131, so that the blocking portion 211 moves from the first position to the middle position where the knife shaft 15 can pass at the first speed, and then moves from the middle position to the second position at the second speed. When the abutting piece 311 is separated from the inclined mating surface 2131, the abutting piece 311 can continue to ascend, and the blocking structure 21 enters the idle stroke stage.

Because the inclination angle α of the first inclined matching surface 2131a relative to the output shaft 13 is greater than the inclination angle α of the second inclined matching surface 2131b relative to the output shaft 13, when the main frame 4 is assembled to the cup body 3, the abutting pieces 311 respectively abut against the two inclined matching surfaces 2131 in a sliding manner, the opening speed of the blocking structure 21 is transited from the initial fast section to the slow section, so that the blocking structure 21 rapidly moves to the middle position where the cutter shaft 15 can pass through in the fast section, and then slowly moves from the middle position to the second position, the stroke distance of the blocking structure 21 is reduced by using the slow section, the space occupation of the protection assembly 2 is reduced, and the friction and wear problem caused by the fact that the clutch or the cutter shaft 15 moves up and down to touch the blocking structure 21 is avoided.

It should be noted that the inclination angle α of the first inclined mating surface 2131a with respect to the output shaft 13 may be greater than or equal to 40 ° and less than or equal to 52 °, and when the inclination angle α of the first inclined mating surface 2131a with respect to the output shaft 13 is 45 °, the blocking portion 211 can move from the first position to the intermediate position through which the arbor 15 can pass, and a good opening and closing effect with respect to the arbor assembling hole 111 is obtained. The inclination angle α of the second inclined mating surface 2131b with respect to the output shaft 13 may be greater than 0 ° and less than or equal to 40 °, and when the inclination angle α of the first inclined mating surface 2131a with respect to the output shaft 13 is 30 °, the blocking portion 211 may be moved from the intermediate position through which the arbor 15 may pass to the second position, thereby obtaining a better opening and closing effect with respect to the arbor assembling hole 111.

In another embodiment, the force-receiving portion 213 may include an inclined engagement surface 2131, and when the host 4 is assembled to the cup body 3, the abutting member 311 slidably abuts against the inclined engagement surface 2131, so that the blocking portion 211 moves from the first position to the second position at a constant speed. As shown in fig. 8, the inclined engagement surface 2131 may be a third inclined engagement surface 2131c, and when the contact piece 311 is separated from the inclined engagement surface 2131c, the contact piece 311 may continue to rise, and the blocking structure 21 enters the idle stroke stage. The inclination angle α of the third inclined mating surface 2131c with respect to the output shaft 13 may be greater than 0 ° and less than or equal to 50 °, and when the inclination angle α of the third inclined mating surface 2131c with respect to the output shaft 13 is 30 °, the blocking portion 211 can obtain a better opening and closing effect with respect to the arbor shaft assembling hole 111. By defining the inclination angle α of the third inclined mating face 2131c with respect to the output shaft 13, the stroke and speed of the baffle structure 21 can be optimized, simplifying the structural arrangement and the reliability of use of the shielding assembly 2.

In the extending direction of the cutter shaft 15, the extending height of the top end of the abutting piece 311 relative to the reference height is larger than or equal to the first height. By limiting the extension height of the top end of the abutting part 311 relative to the reference height of the top end of the cutter shaft 15, the blocking structure 21 is ensured to be completely opened or completely opened in advance when the cutter shaft 15 reaches the cutter shaft assembling hole 111, the structural interference between the cutter shaft 15 and the blocking structure 21 is avoided, and the use reliability of the protection assembly 2 is improved. As shown in fig. 9, in the extending direction of the arbor 15, the extending height of the tip of the abutment 311 with respect to the reference height may be equal to the first height.

As shown in fig. 8 and 10, in the extending direction of the arbor 15, the extending height of the tip of the abutment 311 with respect to the reference height may be larger than the first height. The force-receiving portion 213 may include a third inclined engagement surface 2131c, and when the host 4 is assembled to the cup body 3, the abutting member 311 slidably abuts against the inclined engagement surface 2131, so that the blocking portion 211 moves from the first position to the second position at a constant speed. The inclination angle α of the third inclined mating surface 2131c with respect to the output shaft 13 may be greater than 0 ° and less than or equal to 50 °, and when the inclination angle α of the third inclined mating surface 2131c with respect to the output shaft 13 is 30 °, the blocking portion 211 can obtain a better opening and closing effect with respect to the arbor shaft assembling hole 111.

In the extending direction of the arbor 15, when the stopper 211 is in the initial position, the second height of the bottom end of the inclined mating face 2131 with respect to the reference height is less than or equal to the first height. By limiting the second height of the bottom end of the inclined matching surface 2131 relative to the reference height when the baffle 211 is in the initial position, the baffle structure 21 is ensured to be completely opened or completely opened in advance when the cutter shaft 15 reaches the cutter shaft assembling hole 111, the structural interference between the cutter shaft 15 and the baffle structure 21 is avoided, and the use reliability of the protection assembly 2 is improved.
