Description
Technical Field
[0001] The utility model relates to the technical field of kitchen machine electrical appliances, and in particular to a protective cover for preventing black powder from falling, a stirring component and a kitchen machine. Background Art
[0002] When using a food processor, its driving part drives the stirring accessories such as dough hooks and stirring paddles to rotate to achieve various functions such as dough stirring, egg white whipping, butter mixing, etc. In order to ensure flexibility and versatility, the power end of the driving part and the stirring accessories are often detachably connected through a shaft and a connecting seat, so that users can replace different stirring accessories according to the type of ingredients and cooking needs.
[0003] However, during the operation of the food processor, the stirring accessory will be subject to resistance from the food, and will produce friction or collision with the power shaft, etc., and since both are usually made of metal, the friction or collision will produce metal powder (i.e. black powder) that will fall into the food and mix with it.
[0004] In the prior art, a ring-shaped non-metallic protective sleeve with openings at both ends is usually installed at the connection between the stirring accessory and the power shaft to prevent black powder from falling into the stirring container from the side of the connection between the stirring accessory and the power shaft. Since the protective sleeve is ring-shaped, it is very convenient to remove and clean it after use.
[0005] However, during use, it was found that the protective cover had openings at both ends, and black powder generated by the collision or friction between the stirring accessory and the power shaft would leak out from the bottom opening and fall into the food, thereby endangering the user's health and affecting the user's experience. Utility Model Content
[0006] In order to overcome the defects of the above-mentioned prior art, the utility model provides a sheath, a stirring assembly and a food processor that can prevent black powder from falling. The sheath covers the connection between the active part and the driven part. As a result, the black powder generated by friction and collision between the active part and the driven part remains in the inner cavity. At the same time, since the other end of the sheath is sealed, the black powder will not fall to the outside from the other end of the sheath, thereby preventing the black powder from falling into the food and causing harm to the user's health, thereby improving the user experience.
[0007] The technical solution adopted by the utility model to solve the problem is:
[0008] A sheath for preventing black powder from falling, which is used to be installed at the connection between the active part and the driven part, and the sheath is provided with an inner cavity with one end open and the other end sealed; the sheath is arranged on the outside of the driven part or the active part, and covers the connection between the active part and the driven part;
[0009] Wherein, a connecting hole communicating with the inner cavity is opened on the side of the sheath, and the other end of the follower extends out of the connecting hole.
[0010] Furthermore, the sheath is made of non-metallic material.
[0011] Furthermore, a connector is provided on the side of the sheath, a channel communicating with the connecting hole is provided inside the connector, and the connector wraps a portion of the driven member close to the active member.
[0012] Further, the shape of the channel is adapted to the contour of the driven member portion close to the active member.

[0014] The protective sleeve is sleeved on the outside of the connecting seat and covers the connection and matching part between the connecting groove and the active part or the driven part.
[0015] Furthermore, a protrusion extending outward is provided at the top of the connecting seat, a convex edge extending outward is provided at the top of the sheath, and a groove engaged with the protrusion is provided in the convex edge.
[0016] Furthermore, the convex edge is provided with a first flange which is gathered inwardly and abuts against the top end of the connecting seat.
[0017] Furthermore, the top end of the sheath is provided with a second flange which is gathered inwards and abuts against the top end of the connecting seat.
[0018] Furthermore, a clamping block is provided on the other side of the driven member and the active member, and an anti-drop connection groove communicating with the connection groove is provided on the side of the connection seat;
[0019] When the other of the driven member and the active member is connected to the connection groove, the clamping block is clamped in the anti-detachment connection groove and restricts the other of the driven member and the active member from detaching from the connection groove.
[0020] A food processor comprises the stirring assembly.
[0021] To sum up, the sheath of the utility model covers the connection between the active part and the driven part. Therefore, the black powder generated by friction and collision between the active part and the driven part remains in the inner cavity. At the same time, since the other end of the sheath is sealed, the black powder will not fall to the outside from the other end of the sheath. In addition, a connecting hole is provided on the side of the sheath, so that the component passes through the connecting hole, and the part where the black powder is generated is fully wrapped, thereby preventing the black powder from falling into the food and causing harm to the user's health, thereby improving the user experience.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0036] Embodiment 1
[0037] like Figure 1-2 A black powder-preventing sheath shown is used to be installed at the connection between the active part and the driven part 2. The sheath 1 is cylindrical and has an inner cavity 11 with an opening at one end and a sealing at the other end. The sheath 1 is sleeved on the outside of the driven part 2 or the active part, and covers the connection between the active part and the driven part 2. A connecting hole 121 connected to the inner cavity 11 is provided on the side of the sheath 1, and the other end of the driven part 2 protrudes out of the connecting hole 121.
[0038] Based on the above structure, when using the protective sleeve for preventing black powder from falling of the utility model, the active part and the driven part 2 are detachably connected, and the output of the active part is transmitted to the driven part 2 to drive the driven part 2 to rotate, thereby causing the driven part 2 to rotate and stir the food; the protective sleeve 1 is sleeved on the outside of the driven part 2 or the active part, and covers the connection and cooperation between the active part and the driven part 2; that is, the connection and cooperation between the driven part 2 and the active part is located in the inner cavity 11 provided in the protective sleeve 1, and the black powder generated by the collision or friction between the driven part 2 and the active part during rotation will remain in the inner cavity 11, thereby preventing the black powder from falling into the food and endangering the health of the user. At the same time, since the other end of the protective sleeve 1 is sealed, the black powder will not be thrown out from the bottom end of the protective sleeve 1 during the rotation of the protective sleeve 1 when remaining in the inner cavity 11.
[0039] Furthermore, the sheath 1 is made of non-metallic materials, specifically, the sheath 1 can be made of rubber, plastic, resin, etc. For example, rubber can be used, which has a certain degree of softness, is convenient for assembly in production, and is convenient for users to disassemble and clean the sheath 1 after long-term use, when there is a lot of black powder accumulated in the sheath 1.
[0040] Specifically, a connector 12 is provided on the side wall of the sheath 1, and a channel connected to the connecting hole 121 is provided in the connector 12; the connector 12 wraps the portion of the follower 2 close to the active part. The shape of the channel in the connector 12 is adapted to the contour of the portion of the follower 2 close to the active part, so that the connector 12 can be used to wrap the portion of the follower 2 close to the active part, thereby improving the effect of preventing black powder from falling. In this embodiment, the portion of the follower 2 close to the active part is roughly circular, so the connector 12 and the connecting hole 121 are also designed to be roughly circular, so as to improve the adaptation of the connecting hole 121 to the other end of the follower 2, thereby improving the tight coverage between the connector 12 and the other end of the follower and the active part, and preventing black powder from leaking from the connection between the active part and the other end of the follower 2 and falling into the food, thereby causing harm to the health of the user.
[0041] Specifically, the connector 12 can extend 5-20 mm outward from the side wall of the sheath 1 to achieve a good overall effect in wrapping the connection part between the driven part 2 and the active part and facilitating assembly. In addition, the distance between the connector 12 and the sealing end of the sheath 1 is designed to be greater than the distance between the connection between the driven part 2 and the active part and the bottom of the active part, so as to form a gap between the bottom of the active part and the bottom of the inner cavity of the sheath 1, increase the space for storing black powder in the sheath 1, and extend the interval time for user maintenance and cleaning.
[0042] Among them, rounded corners are used for transition between the connector 12 and the sheath 1, as well as between the side wall and the bottom wall of the sheath 1, so as to reduce the stress between the connector 12 and the side wall of the sheath 1, as well as between the side wall and the bottom wall of the sheath 1, and avoid cracking between the connector 12 and the side wall of the sheath 1, as well as between the side wall and the bottom wall of the sheath 1, causing the black powder in the inner cavity 11 to leak out and fall into the food, endangering the health of the user.
[0043] Embodiment 2
[0044] See also Figure 3-4 In this embodiment, the difference between the sheath 1 and the above-mentioned embodiment 1 is that, in this embodiment, the portion of the follower 2 close to the active member is roughly long and flat, so the connecting head 12 and the connecting hole 121 are also designed to be long and flat, so as to adapt to the other end of the follower 2 extending from the connecting hole 121 as a long and flat shape, thereby also improving the covering of the connection between the other end of the follower 2 and the active member, preventing black powder from leaking from the connection between the active member and the other end of the follower 2 and falling into the food, thereby causing harm to the health of the user.
[0045] Embodiment 3
[0046] like Figure 7-9A stirring assembly shown in the figure includes the above-mentioned embodiment 1 and embodiment 2 to prevent black powder from falling, a driving part and a driven part 2, one of the driven part 2 and the driving part is provided with a connecting seat 21, the connecting seat 21 is provided with a connecting groove 211, and the other of the driven part 2 and the driving part is detachably connected to the connecting groove 211; the sleeve 1 is sleeved on the outside of the connecting seat 21, and covers the connection between the connecting groove 211 and the driving part or the driven part 2.
[0047] Based on the above structure, when the driven member 2 is provided with a connecting seat 21, the active member and the connecting seat 21 are detachably connected, and the output of the active member is transmitted to the connecting seat 21 to drive the connecting seat 21 to rotate, thereby causing the driven member 2 to rotate and stir the food; when the active member is provided with a connecting seat 21, the driven member 2 and the connecting seat 21 are detachably connected, and the output of the active member is transmitted to the driven member 2 through the connecting seat 21 to drive the driven member 2 to rotate, thereby causing the driven member 2 to rotate and stir the food; the sheath 1 is sleeved on the outside of the connecting seat 21, The connection and matching part between the connecting groove 211 and the active part or the driven part 2 is covered, that is, the connection and matching part between the connecting groove 211 and the active part or the driven part 2 is located in the inner cavity 11 provided in the sheath 1. Black powder generated by collision or friction between the connecting seat 21 and the active part or the driven part 2 during rotation will remain in the inner cavity 11, thereby preventing the black powder from falling into the food and endangering the health of the user. At the same time, since the other end of the sheath 1 is sealed, the black powder will remain in the inner cavity 11 and will not be thrown out from the other end of the sheath 1 during the rotation of the sheath 1.
[0048] Furthermore, the top of the connection seat 21 is provided with a protrusion 213 extending outward, the upper end of the sleeve 1 is provided with a flange 13 extending outward, and a groove 131 is provided in the flange 13 to engage with the protrusion 213; wherein, the flange 13 is provided with a first flange 132 that is gathered inward and abuts against the top of the connection seat 21. It should be noted that the engagement of the protrusion 213 and the groove 131 can improve the firmness of the sheath 1 and the connection seat 21, and prevent the sheath 1 from falling off during rotation. At the same time, the first flange 132 that is gathered inward and abuts against the top of the connection seat 21 is provided on the flange 13, which can improve the coverage of the top of the sheath 1, and prevent the top of the sheath 1 from falling off during the rotation of the connection seat 21, causing the black powder to leak out.
[0049] Specifically, a card block (not marked in the figure) is provided on the other side of the driven member 2 and the active member, and an anti-disengagement connecting groove 212 connected to the connecting groove 211 is opened on the side of the connecting seat 21; when the other side of the driven member 2 and the active member is connected to the connecting groove 211, the card block is engaged in the anti-disengagement connecting groove 212 and restricts the other side of the driven member 2 and the active member from disengaging from the connecting groove 211.
[0050] Reference Fig. 9The anti-slip connection groove 212 is roughly Z-shaped, that is, it includes a first horizontal section, an inclined section and a second horizontal section, wherein the second horizontal section is higher than the first horizontal section. When the active member is connected to the driven member 2, the block on the active member or the driven member 2 enters along the connection groove 211 of the connecting seat 21 and extends from the first horizontal section of the anti-slip connection groove 212, and then enters the second horizontal section along the inclined section to complete the installation of the two. When kneading dough and other operations are being performed, the block tends to move up and down in the anti-slip connection groove 212 under the influence of the force of the dough and other forces. At this time, the block can be prevented from moving up and down in the anti-slip connection groove 212 due to the restriction of the second horizontal section, thereby reducing the amount of black powder generated by the friction and collision of the block moving up and down, and further improving the anti-black powder effect of the anti-black powder structure of this embodiment.
[0051] In this embodiment, the driven member 2 is a stirring rod, and the active member is an output shaft of a motor for driving the stirring rod to rotate.
[0052] Embodiment 4
[0053] See also Figure 5-6 In this embodiment, the difference between the sheath 1 and the above-mentioned embodiment 3 is that no protrusion 213 is provided on the connecting seat 21, and a second flange 14 that is retracted inward and abuts against the top of the connecting seat 21 can be provided at the top of the sheath 1 to improve the covering property of the top of the sheath 1 on the top of the connecting seat 21 and prevent the top of the sheath 1 from falling out.
[0054] Embodiment 5
[0055] like Fig. 9 A food processor shown in the figure comprises a machine body and a stirring assembly as described in the third or fourth embodiment above, wherein a driving motor is further provided on the machine body, the active member is an output shaft provided on the driving motor, the driven member 2 is a stirring rod, the stirring rod comprises a stirring hook 22 and a connecting seat 21 provided at the end of the stirring hook 22, a connecting groove 211 is provided on the connecting seat 21, the output shaft on the driving motor is inserted into the connecting groove 211 to realize the transmission connection between the stirring rod and the driving motor, thereby driving the stirring hook 22 to stir dough or whip egg white, etc. The sheath 1 is sleeved on the outside of the connecting seat 21, and covers the connection and matching part between the output shaft of the driving motor and the connecting seat 21.
[0056] It should be noted that the stirring hook 22 may include but is not limited to a dough hook, a whipping stick, etc. The above structure can ensure that when the food processor is working, the black powder generated by the collision and friction between the connecting groove 211 and the output shaft of the driving motor during operation will be retained in the inner cavity 11 of the sheath 1, thereby preventing the black powder from falling into the food and causing harm to the user's health.
[0057] To sum up, the sheath 1 of the utility model covers the connection between the connecting seat 21 and the output shaft of the driving motor, so that the black powder generated by the friction and collision between the connecting groove 211 and the output shaft of the driving motor remains in the inner cavity 11. At the same time, since the other end of the sheath 1 is sealed, during the rotation of the connecting seat 21, the black powder will not fall to the outside from the other end of the sheath 1. In addition, a connecting hole 121 is provided on the side of the sheath 1, so that the stirring hook 22 passes through the connecting hole 121, and the part where the black powder is generated is fully wrapped, thereby preventing the black powder from falling into the food and causing harm to the user's health, thereby improving the user experience.
[0058] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.
