Description

Technical Field

[0001] The utility model belongs to the field of food processor components, and in particular relates to a rotating powder blocking component. Background Art

[0002] Existing food processors are provided with a feed box containing powdered materials, each of which has an opening at the bottom, and multiple feed boxes are arranged side by side along the length of the food processor. The powdered materials are discharged by driving a powder discharge mechanism located inside the feed box. Since the powder discharge mechanism cannot completely cover the opening at the bottom of the feed box after the discharge is completed, there will be a small gap, and moisture can easily enter the feed box, causing the powdered materials to become damp and clump, thereby affecting the discharge. In addition, the powdered materials are also prone to mold growth after becoming damp, which affects human health. In order to prevent the powdered materials in the feed box from becoming damp and caking, a sealing powder blocking device is provided on the back plate of the food processor housing, which includes a movable bracket that can move horizontally, a slide groove is provided on the movable bracket, a fastener is installed on the back plate through the slide groove, and a sealing edge with a sealing gasket is provided on the movable bracket. By driving the movable bracket to move horizontally, the sealing edge is achieved. When the sealing edge is located below the opening of the feed box, the movable bracket is slightly lifted up by an electromagnet, and the sealing gasket seals the opening of the feed box. Since the movable bracket needs to move back and forth horizontally and then be lifted up every time the material is unloaded, the movable bracket will collide with the fasteners at the joints between the movable bracket and the support plate. After multiple movements, the fasteners are easy to loosen and the movable bracket is also easy to deform under the action of external force. Therefore, the overall horizontal movement structure of the sealing powder blocking device of the existing food processor is unstable and prone to failure. Utility Model Content

[0003] Aiming at the problem that the sealing powder blocking device of the existing food processor has an unstable structure and is prone to failure due to the overall lateral movement, the utility model provides a rotating powder blocking assembly, which blocks powder through the rotation of the turntable and has a stable structure.

[0004] The utility model adopts the following technical solution: a rotating powder blocking component, comprising a supporting tray and a turntable accommodated on the supporting tray (1), the turntable being able to rotate under the action of an external force, the turntable being provided with at least one clearance opening, the clearance opening being passed through the turntable from top to bottom, the area between the contour edge of the clearance opening and the contour edge of the turntable forming a shielding portion, the shielding portion being used to shield the powder discharge opening capable of discharging powder; when the turntable is rotated under the action of an external force, the clearance opening is directly opposite to the powder discharge opening or the shielding portion shields the powder discharge opening.

[0005] The entire rotating powder blocking assembly does not use fasteners for coordination, so there is no need to worry about the fasteners loosening under external force. The tray is equipped with a turntable, and only the turntable is rotated by external force. Through this rotation, the two states of the yield port and the powder discharge port are directly facing each other or the shielding part covers the powder discharge port are switched. There is no need to rotate the powder blocking assembly as a whole. Not only is the structure stable, but the operation is also simple and easy.

[0006] Furthermore, the turntable is provided with at least one first ridge, the first ridge having a first inclined surface tilted along the direction of rotation, and the support tray is provided with a second ridge in contact with the first ridge, the second ridge having a second inclined surface tilted along the direction of rotation. When the clearance port is directly opposite the powder discharge port, the first inclined surface overlaps and contacts the second inclined surface. When the shielding portion blocks the powder discharge port, the first inclined surface and the second inclined surface are partially offset so that the second ridge pushes up the first ridge, thereby pushing up the turntable. In this arrangement, when the turntable rotates, it can be pushed upward by the support tray, so that the shielding portion on the turntable is in close contact with the discharge port, further ensuring a good sealing effect.

[0007] Furthermore, the tray is provided with a rim for accommodating the turntable, the height of which is adapted to the thickness of the turntable. The entire rotating powder blocking assembly is a flat structure, which allows the turntable to be embedded in the tray and is not easily bumped by other components during rotation, thereby ensuring the effectiveness of the rotation.

[0008] As an improvement, the turntable is provided with a groove, and the surrounding edge is provided with a misalignment prevention component. The misalignment prevention component includes a protrusion adapted to fit within the groove, constrained by the surrounding edge, and maintained in an extended position by a spring disposed thereon. The purpose of providing the misalignment prevention component is to facilitate initial positioning of the turntable. The spring provides an inward support force perpendicular to the surrounding edge for the protrusion, and the protrusion is constrained by the surrounding edge. This ensures that the protrusion remains extended, allowing it to move along the contour of the turntable as it rotates until it falls into the groove.

[0009] As another improvement, a magnetic member is embedded in the upper surface of the turntable.

[0010] Furthermore, the turntable is provided with rotating teeth at at least part of the contour edge, and a clearance hole is provided on one side of the supporting tray, and the rotating teeth can extend from the clearance hole, and the rotating teeth can engage with a gear so that the turntable can be rotated by external force acting on the gear.

[0011] Furthermore, a hook is provided on the edge of the tray, and the hook protrudes from the clearance hole. The hook protruding from the clearance hole can be inserted into the gear and shielded by the gear. When the gear is in operation, the tray will not be accidentally removed, ensuring safe use.

[0012] Furthermore, the support tray is provided with a through hole extending vertically therethrough, and the projection of the rotation path of the clearance opening falls within the area enclosed by the through hole. By providing clearance space for the turntable, powdered materials can fall downward from the through hole through the clearance opening when unloading.

[0013] Furthermore, the turntable is provided with an arcuate groove, and the support tray is provided with a limit rod, which is inserted into the arcuate groove. When the turntable rotates, the arcuate groove is constrained by the limit rod, thereby limiting the swing angle of the turntable. This configuration is a further error prevention mechanism, effectively preventing safety accidents caused by excessive rotation of the turntable.

[0014] Furthermore, two concave cavities are symmetrically provided on the support tray, and the two concave cavities extend along the length direction of the support tray. One end of the concave cavity is a wide end, and the other end is a narrow end, and the narrow end is close to the turntable.

[0015] The beneficial effects of the present invention are as follows: the present application is a rotating powder blocking assembly, the entire rotating powder blocking assembly does not use fasteners for cooperation, and there is no need to worry about the fasteners loosening under the action of external force. The supporting tray carries the turntable, and the turntable is only rotated by external force. Through the rotation action, the turntable is switched between the two states of the yield port facing the powder outlet or the shielding part shielding the powder outlet. There is no need to rotate the powder blocking assembly as a whole, which is not only structurally stable but also simple and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the accompanying drawings of the present invention. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0023] Example 1

[0024] This embodiment is a rotating powder blocking component, such as Figures 1 to 3 As shown, it includes a tray 1 and a turntable 2 accommodated on the tray 1, and the turntable 2 is provided with four clearance openings 21, which are equidistantly arranged along the circumference. The clearance openings 21 pass through the turntable 2 from top to bottom, and the area between the contour edge of the clearance opening 21 and the contour edge of the turntable 2 forms a shielding portion 22 for shielding the powder outlet; the contour edge of the turntable 2 is provided with rotating teeth 23, and the rotating teeth 23 can engage with the gear so that the turntable 2 can be rotated by the external force acting on the gear. It can be driven by the gear sleeved on the motor drive shaft, or by turning the gear to rotate the gear and drive the turntable 2 to rotate, so that the clearance opening 21 is opposite to the powder outlet or the shielding portion 22 shields the powder outlet. Therefore, when the turntable 2 is driven by the motor to rotate, the turntable 2 switches between the state of allowing powder to fall and the state of shielding the powder outlet. In this embodiment, the shielding portion 22 specifically contacts the bottom edge of the powder outlet from bottom to top to shield the powder outlet.

[0025] The entire rotating powder blocking assembly does not use fasteners for coordination, so there is no need to worry about the fasteners loosening under the action of external force. The supporting tray 1 carries the turntable 2, and only the turntable 2 is driven by external force to rotate. Through this rotation action, the turntable 2 is switched between the two states of the yield port 21 facing the powder outlet or the shielding part 22 shielding the powder outlet. There is no need to rotate the powder blocking assembly as a whole. Not only is the structure stable, but the operation is also simple and easy.

[0026] The turntable 2 is provided with three first ridges 24, and the first ridge 24 has a first inclined surface 241 inclined along the rotation direction. The supporting tray 1 is provided with a second ridge 12 that is in contact with the first ridge 24, and the second ridge 12 has a second inclined surface 121 inclined along the rotation direction. When the give way port 21 is directly opposite to the powder lower port, the first inclined surface 241 overlaps and fits with the second inclined surface 121, that is, the low point of the first ridge 24 corresponds to the high point of the second ridge 12, and the high point of the first ridge 24 and the low point of the second ridge 12 are at the lowest position. When the shielding portion 22 blocks the powder lower port, the first inclined surface 241 is partially staggered with the second inclined surface 121. At this time, the first ridge 24 corresponds to the higher position of the second ridge 12, so that the second ridge 12 pushes up the first ridge 24, and then the turntable 2 is pushed up. In this arrangement, when the turntable 2 rotates, it can be pushed upward by the supporting tray 1, so that the shielding portion 22 on the turntable 2 is close to the discharge port, further ensuring a better sealing effect.

[0027] The receiving tray 1 is provided with a surrounding edge 13 for accommodating the turntable 2. The surrounding edge 13 is provided with an anti-error component 14. The turntable 2 is provided with a groove 25 adapted to the anti-error component 14. When the clearance opening 21 is aligned with the powder discharge opening, the anti-error component 14 is aligned with the groove 25. The anti-error component 14 provided on the surrounding edge 13 is aligned with the groove 25 on the turntable 2. During initial installation, a click sound is produced to indicate that the turntable 2 is in place. The click sound can also be used to determine whether the turntable 2 has returned to its original position by detecting whether the sound is produced.

[0028] The error-proofing assembly 14 includes a protruding member 141 that is restrained by the edge 13. The protruding member 141 is maintained in an extended position by a spring 142 disposed thereon. The spring 142 provides a supporting force perpendicular to the edge 13 and inwardly directed toward the protruding member 141. Furthermore, the protruding member 141 is restrained by the edge 13, so that the protruding member 141 remains in an extended position. As the turntable 2 rotates, the protruding member 141 can move along the contour of the turntable 2 until it falls into the groove 25.

[0029] The height of the edge 13 is adapted to the thickness of the turntable 2. The entire rotating powder blocking assembly is a flat structure, which allows the turntable 2 to be embedded in the support tray 1. The turntable 2 is not easily bumped by other components when rotating, thereby ensuring the effectiveness of the rotation.

[0030] A clearance hole 11 is provided on one side of the tray 1, and the rotating tooth 23 can extend from the clearance hole 11. The rotating tooth 23 extends from the clearance hole 11 to avoid interference with other parts of the tray 1.

[0031] The edge of the tray 1 is provided with a hook 17, which protrudes from the clearance hole 11. The hook 17 protruding from the clearance hole 11 can be inserted into the gear and shielded by the gear. When the gear drives the turntable 2 to rotate and the shielding portion 22 covers the lower powder outlet, the tray 1 will not be accidentally removed, ensuring safe use.

[0032] The support tray 1 is provided with a through hole 15 extending vertically therethrough. The projection of the rotational path of the clearance opening 21 falls within the area enclosed by the through hole 15. By providing clearance space for the turntable 2, when the clearance opening 21 is aligned with the powder discharge port, powdered material can fall downward from the through hole 15 through the clearance opening 21. In this embodiment, the area enclosed by the outline of the through hole 15 and the surrounding edge 13 forms the support surface for the turntable 2, effectively preventing the turntable 2 from falling.

[0033] The turntable 2 is provided with an arcuate groove 26, and the support tray 1 is provided with a limit rod 16, which is inserted into the arcuate groove 26. When the turntable 2 rotates, the arcuate groove 26 is constrained by the limit rod 16, thereby limiting the swing angle of the turntable 2. This configuration further prevents accidents caused by excessive rotation of the turntable 2. In this embodiment, the arcuate groove 26 is located inside the area enclosed by the first protrusion 24, near the through hole 15.

[0034] Two symmetrical recessed cavities 18 are provided on the tray 1, extending along its length. These recessed cavities 18 are wide at one end and narrow at the other, with the narrow end being closer to the turntable. These narrow recessed cavities can be placed on a supporting structure to prevent the tray 1 from easily falling out. This allows the tray 1 to be raised, creating an unobstructed area below it to prevent interference with material removal. In this configuration, the tray 1 can be constructed as a drawer-like sliding structure, making installation more convenient.

[0035] Example 2

[0036] like Figure 4 and Figure 5 As shown, this embodiment differs from embodiment 1 in that a magnetic member 27 is embedded in the upper surface of the turntable 2, and the magnetic member 27 is induced by a magnetic induction component to achieve positioning. In this arrangement, the magnetic induction component is set on another component that can cooperate with the rotating powder blocking assembly, which provides non-contact positioning.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments. Any modifications that do not deviate from the functional and structural principles of the present invention are intended to be included within the scope of the claims.
