Description

Technical Field

[0001] This invention relates to the field of cleaning tools technology, specifically to a winnowing basket. Background Technology

[0002] Currently, dustpans with foldable handles can rotate relative to the handle, allowing them to be in both unfolded and folded states. However, during use, many dustpans, due to insufficient manufacturing precision or deformation from long-term use, do not have a completely flush opening with the ground. This incomplete flushing allows debris or dust to enter the gap between the bottom of the dustpan and the ground, resulting in low cleaning efficiency and incomplete cleaning.

[0003] In practical use, when the opening of the winnowing basket cannot be completely flush with the ground, a force can be applied to the basket handle to move it closer to the basket, causing the opening to deform and become flush with the ground. However, this operation will result in the force applied to the basket handle being in the same direction as the force applied when folding the winnowing basket, which can easily lead to the basket handle being folded incorrectly, affecting the user experience. Summary of the Invention

[0004] In view of this, the present invention provides a winnowing basket to solve the problem that current foldable winnowing baskets are prone to incorrectly folding the basket handle during use.

[0005] This invention provides a winnowing basket, comprising:

[0006] A winnowing basket, wherein the winnowing basket has a rim at one end along its length, through which garbage can enter the interior of the winnowing basket;

[0007] A rotating rod, one end of which is rotatably mounted on the winnowing basket, so that the rotating rod can rotate relative to the winnowing basket along the length of the winnowing basket, so that the winnowing basket is in a folded state or a working state;

[0008] A locking assembly, which is throttle connected between the scoop and the rotating rod;

[0009] The locking component can be driven to rotate around its own circumference, so that the locking component can switch between an unlocked state and a locked state.

[0010] When the locking assembly is in the unlocked state, the rotating rod can rotate relative to the winnowing basket along the length of the winnowing basket to move closer to or further away from the edge of the winnowing basket, so that the winnowing basket is in a folded state;

[0011] When the locking assembly is in the locked state, the rotation of the rotating rod along the length of the hopper is restricted.

[0012] Beneficial effects: This invention provides a winnowing basket with a locking component between the basket and a rotating rod. The locking component, driven to rotate circumferentially, switches between an unlocked and a locked state, controlling the rotating rod to be in a rotatable state and a restricted, non-rotatable state. When the locking component is in the unlocked state (i.e., the rotating rod can rotate), the rotating rod is folded for easy storage of the winnowing basket. When the locking component is in the locked state (i.e., the rotation of the rotating rod is restricted), the rotating rod's position is fixed to ensure the winnowing basket functions properly. This solves the problem of incorrect folding of the winnowing basket rod during use in current foldable winnowing baskets, improving the user experience.

[0013] In one optional embodiment, the locking assembly includes a first rotating part and a second rotating part connected to each other, and the rotating rod is connected to the winnowing basket through the first rotating part and the second rotating part;

[0014] The first rotating part is rotatably connected to the rotating rod via a first rotating shaft, so that the rotating rod is rotatably disposed on the winnowing basket and can move closer to or away from the edge of the winnowing basket with the axis of the first rotating shaft as the axis of rotation, so that the winnowing basket is in a folded state;

[0015] The second rotating part is circumferentially connected to the winnowing basket and can rotate relative to the winnowing basket along its own circumference, so that when the rotating rod rotates along its own circumference, it can drive the first rotating part and the second rotating part to rotate synchronously, thereby driving the first rotating shaft to rotate circumferentially, so that the locking assembly rotates to the unlocked state or the locked state.

[0016] When the locking component is in the unlocked state, the axial direction of the first rotating shaft is perpendicular to the length direction of the winnowing basket;

[0017] When the locking assembly is in the locked state, the axial direction of the first rotating shaft is not perpendicular to the length direction of the scoop.

[0018] Beneficial effects: The locking assembly is constructed by using a first rotating part and a second rotating part. The first rotating part is rotatably connected to the rotating rod through a first rotating shaft to facilitate the folding of the winnowing basket. The second rotating part is rotatably connected to the winnowing basket to allow the rotating rod to rotate around its own circumference, thereby changing the orientation of the first rotating shaft and thus achieving the locking and unlocking of the locking assembly.

[0019] In one optional embodiment, the winnowing basket is provided with a mounting groove, and the second rotating part is inserted into the mounting groove so that the second rotating part is circumferentially connected to the winnowing basket.

[0020] Beneficial effects: The installation groove is set in the hopper to facilitate the second rotating part of the locking component to be inserted and engaged with the installation groove for rotatable installation. The structure is simple and the connection is reliable.

[0021] In one optional embodiment, one of the second rotating part and the mounting groove is provided with an annular groove, and the other is provided with a buckle;

[0022] The second rotating part is inserted into the mounting groove, so that the buckle engages with the annular groove, and the annular groove can rotate circumferentially relative to the buckle.

[0023] Beneficial effects: The second rotating part and the mounting groove are circumferentially rotated through the snap-fit ​​of the annular groove and the buckle, which is simple in structure and reliable in connection.

[0024] In one optional embodiment, the mounting groove is a through groove. When the second rotating part is inserted into the mounting groove, the buckle communicates with the outside through the bottom of the through groove to facilitate adjustment of the fit between the buckle and the annular groove.

[0025] Beneficial effects: The mounting slot is a through slot so that users can directly adjust the fit between the buckle and the annular slot through the bottom of the hopper, thereby facilitating the disassembly and assembly of the rotating rod.

[0026] In one optional embodiment, a one-way limiting mechanism is provided between the second rotating part and the mounting groove, so that the second rotating part can rotate unidirectionally relative to the winnowing basket.

[0027] Beneficial effect: A one-way limiting mechanism is provided between the second rotating part and the mounting groove to control the second rotating part to rotate only in one direction relative to the hopper, so as to avoid excessive wear between the second rotating part and the inner wall of the mounting groove when it is driven to rotate.

[0028] In one optional embodiment, the one-way limiting mechanism includes at least one one-way groove and at least one limiting ratchet that cooperate with each other. One of the at least one one-way groove and the at least one limiting ratchet is provided on the outer wall of the second rotating part, and the other is provided on the inner wall of the mounting groove. The second rotating part rotates unidirectionally relative to the hopper by engaging at least one of the one-way grooves and at least one of the limiting ratchets.

[0029] Beneficial effects: The one-way rotational engagement between the second rotating part and the mounting groove is achieved through the one-way groove and the limiting ratchet structure, which is simple in structure and reliable in connection.

[0030] In one optional embodiment, a limiting component is provided between the first rotating part and the rotating rod, the limiting component being able to restrict the rotating rod from rotating relative to the first rotating part along the first rotating axis, so as to fix the position of the rotating rod relative to the winnowing basket.

[0031] Beneficial effect: By setting a limiting component between the first rotating part and the rotating rod, the stability is improved so as to keep the winnowing basket in a folded state or in a working state.

[0032] In one optional implementation, the limiting component includes:

[0033] Multiple grooves are distributed circumferentially on the first rotating part along the first rotation axis;

[0034] A limiting protrusion is provided on the rotating rod and can cooperate with the groove;

[0035] After the rotating rod rotates relative to the first rotating part, the limiting protrusion can engage with one of the grooves to fix the position of the rotating rod relative to the winnowing basket.

[0036] Beneficial effects: The locking mechanism of multiple grooves and limiting protrusions fixes the position of the rotating rod relative to the first rotating part, keeping the winnowing basket in a folded state or in a working state. The structure is simple and the connection is reliable.

[0037] In one alternative embodiment, the limiting protrusion is configured as an elastic sheet protruding toward the groove;

[0038] Alternatively, the limiting protrusion may include an elastic component.

[0039] Beneficial effects: Setting the limiting protrusion as an elastic sheet or elastic component makes it easier to apply force to the groove using elastic deformation, ensuring the stability of the limiting protrusion deformation and reset.

[0040] In one alternative embodiment, the winnowing basket further includes a winnowing basket rod connected to the end of the rotating rod away from the winnowing basket.

[0041] Beneficial effect: The winnowing basket rod is used as an extension rod to connect with the rotating rod, making it convenient for users to use.

[0042] In one alternative embodiment, the winnowing basket rod and the rotating rod are integrally formed or detachably connected;

[0043] Alternatively, the rotating rod may be sleeved on the outside of at least a portion of the winnowing basket rod.

[0044] Beneficial effects: The winnowing basket handle and rotating rod are integrally molded to improve the structural stability of the winnowing basket; the winnowing basket handle and rotating rod are detachably connected to facilitate the packaging and transportation of the winnowing basket at the factory; in addition, users can drive the rotating rod to rotate the winnowing basket handle to switch the locking component to the unlocked or locked state, making it more convenient for users to use.

[0045] In one optional embodiment, the winnowing basket pole is configured as a multi-segment pole, and adjacent segments are threaded together.

[0046] When a one-way limiting mechanism is provided between the second rotating part and the mounting groove, the direction in which the second rotating part can rotate unidirectionally relative to the scoop is the same as the direction of the threaded connection between the rods.

[0047] Beneficial effects: The multi-segment design of the winnowing basket handle facilitates packaging and transportation. Furthermore, the direction in which the second rotating part can rotate unidirectionally relative to the winnowing basket is aligned with the direction of the threaded connection between the handles. This prevents the multi-segment winnowing basket handle from loosening when the second rotating part rotates with the rotating rod and the winnowing basket handle itself, ensuring the structural stability of the winnowing basket.

[0048] In one alternative embodiment, when the locking assembly is in the locked state, the rotating rod can move closer to the scoop about the axis of the first rotating shaft.

[0049] Beneficial effects: When the locking assembly is in the locked state, the rotating rod can move closer to the winnowing basket with the axis of the first rotating shaft as the axis of rotation, so that the rotating rod can drive the winnowing basket rod to fold towards the side of the winnowing basket, making it easier to store the winnowing basket.

[0050] In one optional embodiment, the winnowing basket is provided with a connecting seat, and the rotating rod is rotatably connected to the connecting seat through a second rotating shaft. The axial direction of the second rotating shaft is perpendicular to the length direction of the winnowing basket, so that the rotating rod is rotatably disposed on the winnowing basket and can rotate about the axis of the second rotating shaft as a rotation axis to approach the edge of the winnowing basket, so that the winnowing basket is in a folded state.

[0051] At least a portion of the locking assembly is sleeved inside the rotating rod and is circumferentially rotatable relative to the rotating rod, allowing the locking assembly to switch between an unlocked state and a locked state;

[0052] When the locking component is in the locked state, the locking component engages with the connecting seat;

[0053] When the locking component is in the unlocked state, the locking component is disengaged from the connector.

[0054] Beneficial effects: A connecting seat is provided on the winnowing basket, and the rotating rod is rotatably connected to the connecting seat through a second rotating shaft to facilitate the folding of the winnowing basket; at least part of the locking component is sleeved inside the rotating rod, and the locking component is used to switch between the unlocked and locked states by rotating circumferentially relative to the rotating rod; the locking component in the locked state cooperates with the connecting seat to fix the position of the rotating rod so that the winnowing basket can be kept in working state, and the locking component in the unlocked state is disengaged from the connecting seat to allow the rotating rod to move freely so that the winnowing basket can be folded.

[0055] In one optional embodiment, the locking assembly includes a locking rod and a locking member disposed on the locking rod, a portion of the locking rod being sleeved inside the rotating rod, and the locking member extending out of the rotating rod; when the locking rod rotates circumferentially relative to the rotating rod, it drives the locking member to rotate synchronously; the connecting seat is provided with a mating part that cooperates with the locking member;

[0056] When the locking assembly is in the locked state, the locking member and the mating part cooperate;

[0057] When the locking component is in the unlocked state, the locking element and the mating part are separated.

[0058] Beneficial effects: By using the locking element of the rotating rod extending from the locking assembly to engage or disengage with the mating part provided on the connecting seat, the locking assembly can be switched between locked and unlocked states.

[0059] In one alternative implementation, the locking element and the mating part constitute a first electronic lock.

[0060] Beneficial effects: The first electronic lock controls the engagement and disengagement of the locking element and the mating part, enabling convenient and quick electronic control.

[0061] In one optional embodiment, the locking element is a limiting block disposed on the locking rod, and the mating part is the first sidewall of the connecting seat;

[0062] When the locking component is in the locked state, the limiting block abuts against the first side wall of the connecting seat;

[0063] When the locking component is in the unlocked state, the limiting block separates from the first sidewall of the connecting seat.

[0064] Beneficial effect: By utilizing the limiting block of the rotating rod extending from the locking assembly to cooperate or separate from the first side wall set on the connecting seat, the locking assembly can switch between locked and unlocked states.

[0065] In one alternative embodiment, the sidewall of the rotating rod has a first circumferential opening, and the locking member extends from the first opening of the rotating rod to engage with the mating part.

[0066] Beneficial effect: A first opening is made circumferentially on the side wall of the rotating rod so that the locking member can extend from the side of the rotating rod, thereby realizing the cooperation between the limiting block on the locking member and the first side wall of the connecting seat.

[0067] In one alternative embodiment, a second opening is provided at the bottom of the rotating rod, and the locking member extends from the second opening of the rotating rod to engage with the mating part.

[0068] Beneficial effect: A second opening is made at the bottom of the rotating rod so that the locking element can extend from the bottom of the rotating rod, thereby achieving the engagement of the limiting block on the locking element with the first side wall of the connecting seat.

[0069] In one optional embodiment, the bottom of the locking rod is provided with a limiting flange, which is disposed opposite to the rotating rod to restrict the locking rod from moving toward the top of the rotating rod.

[0070] Beneficial effect: By setting a limiting flange to cooperate with the rotating rod, the locking rod is prevented from moving to the top of the rotating rod, thus ensuring the stability of the winnowing basket during use.

[0071] In one alternative embodiment, the locking assembly further includes a limiting device capable of restricting the circumferential rotation of the locking member relative to the rotating rod.

[0072] Beneficial effect: The limiting device restricts the circumferential rotation of the locking part relative to the rotating rod, so as to prevent the winnowing basket from being folded incorrectly.

[0073] In one alternative implementation, the limiting device is configured as a second electronic lock.

[0074] Beneficial effects: The second electronic lock controls the circumferential rotation of the locking element relative to the rotating rod, achieving convenient and quick electronic control.

[0075] In one optional embodiment, the limiting device is configured as a spring block disposed on the connecting seat, the spring block being able to abut against the locking member so that the locking member abuts against the rotating rod axially, thereby restricting the circumferential rotation of the locking member relative to the rotating rod.

[0076] In one optional embodiment, the outer wall of the rotating rod is provided with a recessed groove, and when the winnowing basket is in a folded state, the spring block can abut against the recessed groove to fix the winnowing basket in a folded state.

[0077] Beneficial effect: When the winnowing basket is folded, the groove on the outer wall of the rotating rod and the spring block are engaged to keep the winnowing basket fixed in the folded state, thus ensuring the structural stability of the winnowing basket in the storage state.

[0078] In one alternative embodiment, the spring block includes a spring that abuts against the connecting seat and extends toward the locking member, and a spring block head disposed on top of the spring, the spring block head being capable of abutting the locking member.

[0079] Beneficial effect: The spring connected to the spring head is provided so that the spring can be used to apply a restoring elastic force to the spring head.

[0080] In one optional embodiment, the limiting device further includes a locking mechanism disposed between the rotating rod and the locking rod. After the locking rod moves along the axial direction of the rotating rod toward the direction of the winnowing basket, the locking mechanism is in a disengaged state, so that the locking rod can rotate circumferentially relative to the rotating rod.

[0081] Beneficial effect: The locking mechanism is set up to control whether the locking rod can rotate circumferentially relative to the rotating rod.

[0082] In one optional embodiment, the engaging mechanism includes a locking block and an opening slot that engages with the locking block, wherein one of the locking block and the opening slot is disposed on the locking member, and the other is disposed on the side wall of the rotating rod.

[0083] After the locking rod moves along the axial direction of the rotating rod towards the hopper, the locking block can separate from the opening slot, allowing the locking rod to rotate relative to the rotating rod.

[0084] Beneficial effects: By utilizing the limiting cooperation and separation of the locking block and the opening slot, the locking rod can be fixed and rotated at a corresponding angle relative to the rotating rod, so as to adjust the position of the locking block and adjust the rotation of the rotating rod relative to the scoop.

[0085] In one optional embodiment, the opening slot includes a first opening slot and a second opening slot distributed circumferentially along the rotating rod;

[0086] After the locking rod moves along the axial direction of the rotating rod towards the direction of the hopper, it can drive the locking member to move, compress the spring block and disengage the locking block from the first opening slot, so that the locking block can be rotated by the locking rod to the second opening slot, and push the locking block to engage with the second opening slot when the spring block is reset.

[0087] Beneficial effects: The first and second opening slots distributed along the circumference of the rotating rod cooperate with the locking block to facilitate changing the locked and unlocked states of the locking assembly.

[0088] In one optional embodiment, the engaging mechanism includes a locking block and a ratchet groove that engages with the locking block, wherein one of the locking block and the ratchet groove is located on the locking member and the other is located on the side wall of the rotating rod.

[0089] After the locking lever rotates circumferentially, the locking block can separate from the ratchet groove, so that the locking lever can rotate relative to the rotating rod.

[0090] Beneficial effects: By utilizing the limiting engagement and disengagement of the locking block and ratchet groove, the locking lever can be fixed and rotated at a corresponding angle relative to the rotating lever, thereby adjusting the position of the locking block and the rotation of the rotating lever relative to the hopper. Furthermore, the engagement of the locking block and ratchet groove allows for unidirectional locking of the locking lever relative to the rotating lever, preventing excessive wear between the locking lever and the inner wall of the rotating lever during driven rotation.

[0091] In one optional embodiment, the ratchet groove includes at least a first ratchet groove and a second ratchet groove distributed circumferentially along the rotating rod;

[0092] The locking lever rotates circumferentially, causing the locking member to rotate, which in turn causes the locking block to rotate and move downward along the first ratchet groove. The spring block compresses and disengages the locking block from the first ratchet groove, allowing the locking block to move to the second ratchet groove by the rotation of the locking lever. When the spring block resets, it pushes the locking block to engage with the second ratchet groove.

[0093] Beneficial effects: The first and second ratchet grooves distributed along the circumference of the rotating rod cooperate with the locking block to facilitate changing the locked and unlocked states of the locking assembly.

[0094] In one optional embodiment, when the locking element is a limiting block disposed on the locking rod, the locking block is the limiting block.

[0095] Beneficial effects: Directly setting the card block as a limit block can simplify the number of structural components and save product production costs.

[0096] In one optional embodiment, when the bottom of the locking rod is provided with a limiting protrusion, and the locking member is a limiting block provided on the locking rod, the limiting protrusion is the limiting block.

[0097] Beneficial effects: Directly setting the limiting protrusion as a limiting block can simplify the number of structural components and save product production costs.

[0098] In one optional embodiment, when the connecting seat is provided with a spring block, the top of the spring block is provided with a plurality of annularly arranged inclined grooves, and the locking block abuts against and engages with the inclined grooves.

[0099] Beneficial effect: Multiple annular inclined grooves are set on the top of the spring block, which can drive the spring block to deform and compress as the block rotates.

[0100] In one alternative embodiment, the winnowing basket further includes a winnowing basket rod connected to the locking assembly at the end away from the winnowing basket.

[0101] Beneficial effect: The winnowing basket rod is used as an extension rod to connect with the rotating rod, making it convenient for users to use.

[0102] In one alternative embodiment, the scoop rod and the locking rod are integrally formed or detachably connected;

[0103] Alternatively, the locking rod may be sleeved on the outside of at least a portion of the scoop rod.

[0104] Beneficial effects: The winnowing basket handle and locking rod are integrally molded to improve the structural stability of the winnowing basket; the winnowing basket handle and locking rod are detachably connected to facilitate the packaging and transportation of the winnowing basket at the factory; in addition, users can drive the rotating rod to rotate the winnowing basket handle to switch the locking component to the unlocked or locked state, making it more convenient for users to use.

[0105] In one optional embodiment, the connecting seat includes a first sidewall, and a second sidewall and a third sidewall connected to and opposite to the first sidewall. The first sidewall, the second sidewall, and the third sidewall together form a receiving cavity. At least a portion of the rotating rod is located in the receiving cavity. The two ends of the second rotating shaft are rotatably connected to the second sidewall and the third sidewall, respectively. The mating part that cooperates with the locking member is the first sidewall.

[0106] Beneficial effects: The connecting seat is designed with a structure in which the first side wall, the second side wall and the third side wall surround and form an opening, so as to facilitate the movement of the rotating rod and the installation of the second rotating shaft.

[0107] In one optional embodiment, the connecting seat further includes a base platform connected to the bottom of the first sidewall, the second sidewall, and the third sidewall; when the locking assembly further includes a spring block, the spring block is disposed on the base platform.

[0108] Beneficial effect: The base provides an installation position for the spring block.

[0109] In one optional embodiment, the locking component has a first position and a second position, and when the locking component rotates between the first position and the second position, the unlocked state and the locked state of the locking component can be switched.

[0110] When the locking component is in the first position, the locking component is in the unlocked state;

[0111] When the locking component is in the second position, the locking component is in the locked state.

[0112] Beneficial effects: Taking the first type of winnowing basket as an example. From the perspective of the diagram, the locking component is in the first position, which is the unlocked state, and the winnowing basket rod can be rotated and folded; from the perspective of the diagram, the locking component is in the second position, which is the locked state, and the winnowing basket rod cannot be rotated.

[0113] In one alternative implementation, the angle between the first position and the second position is 90°.

[0114] Beneficial effect: The angle between the first and second positions is limited to 90° so that the folded winnowing basket rod can be located on the left or right side of the winnowing basket, rather than folded diagonally in front of or behind the winnowing basket, so as to facilitate the storage of the winnowing basket.

[0115] In one optional embodiment, when the winnowing basket further includes a winnowing basket rod, the winnowing basket rod is provided with an inclined handle, and the handle and the winnowing basket rod rotate synchronously.

[0116] Beneficial effect: The handle is connected to the winnowing basket pole, making it easier for users to hold the handle and use the winnowing basket.

[0117] In one alternative implementation, when the locking assembly is in the locked state, the handle is tilted in the direction of the length of the winnowing basket.

[0118] Beneficial effect: When the locking component is in the locked state, the handle is tilted in the direction of the length of the winnowing basket, so that the user can hold the handle to use the winnowing basket.

[0119] In one alternative implementation, when the locking component is in the unlocked state, the handle is tilted in the width direction of the winnowing basket.

[0120] Beneficial effect: When the locking component is in the unlocked state, the handle is tilted in the width direction of the winnowing basket, so that when the winnowing basket rod is folded and stored, the handle is tilted towards the left or right side of the winnowing basket, thereby storing the handle and further reducing the space occupied by the winnowing basket.

[0121] Moreover, when the user is using the winnowing basket normally, the handle is tilted in the direction of the length of the basket, and the locking component is in the locked state, so the winnowing basket can be used normally; when the winnowing basket needs to be stored, the handle is tilted in the direction of the width of the basket, and at this time, the locking component is also in the unlocked state, so the winnowing basket can be stored.

[0122] When the user drives the locking component to the unlocked and locked states using the handle, the handle and the handle rotate synchronously. Therefore, the locking component can be driven to the unlocked and locked states via the handle. When the handle is in the folded state (i.e., the handle's tilt direction is the width direction of the folded hopper), the locking component is in the unlocked state, meaning the folded hopper is foldable. When the handle is in the usable state (i.e., the handle's tilt direction is the length direction of the folded hopper), the locking component is in the locked state, meaning the folded hopper is usable. Thus, the user unlocks the locking component while folding the handle, allowing the folded hopper to be stored away.

[0123] In one alternative implementation, the locking component has a first position and a second position, and the angle between the first position and the second position is 90°;

[0124] The locking component is in the first position, and the handle is tilted in the direction of the width of the winnowing basket;

[0125] The locking component is in the second position, and the handle is tilted in the direction of the length of the winnowing basket.

[0126] Beneficial effect: When the locking component is in the unlocked state, the handle is tilted in the width direction of the winnowing basket, so that when the winnowing basket rod is folded and stored, the handle is tilted towards the left or right side of the winnowing basket, thereby storing the handle and further reducing the space occupied by the winnowing basket.

[0127] Moreover, when the user is using the winnowing basket normally, the handle is tilted in the direction of the length of the basket, and the locking component is in the locked state, so the winnowing basket can be used normally; when the winnowing basket needs to be stored, the handle is tilted in the direction of the width of the basket, and at this time, the locking component is also in the unlocked state, so the winnowing basket can be stored.

[0128] When the user drives the locking component to the unlocked and locked states using the handle, the handle and the handle rotate synchronously. Therefore, the locking component can be driven to the unlocked and locked states via the handle. When the handle is in the folded state (i.e., the handle's tilt direction is the width direction of the folded hopper), the locking component is in the unlocked state, meaning the folded hopper is foldable. When the handle is in the usable state (i.e., the handle's tilt direction is the length direction of the folded hopper), the locking component is in the locked state, meaning the folded hopper is usable. Thus, the user unlocks the locking component while folding the handle, allowing the folded hopper to be stored away.

[0129] In one alternative embodiment, when the winnowing basket is provided with a winnowing basket rod, the winnowing basket rod is located in the middle of the width direction of the winnowing basket.

[0130] Beneficial effect: Placing the winnowing basket handle in the middle of the width of the basket ensures balance on both sides, improving the user experience.

[0131] In one alternative embodiment, when the winnowing basket is in operation, the rotation axis of the locking assembly is parallel to the axis of the rotating rod.

[0132] In one alternative embodiment, the winnowing basket further includes a comb-like part disposed on the winnowing basket, and the comb-like part is detachably connected to the winnowing basket.

[0133] Beneficial effects: The comb teeth located on the dustpan make it easier for users to clean hair and other debris from the broom; the comb teeth are detachably connected to the dustpan for easy packaging and transportation; and the comb teeth are easy to repair and replace.

[0134] In one optional embodiment, comb teeth are provided on the first side of the comb tooth portion; the second side of the comb tooth portion is engaged with the winnowing basket.

[0135] And / or, the two ends of the comb teeth are respectively engaged with the two sides of the scoop;

[0136] And / or, a longitudinal limiting member is provided between the comb teeth and the hopper, the longitudinal limiting member being used to limit the movement or deformation of the comb teeth in the vertical direction;

[0137] And / or, the top of the hopper has a top plate, and the comb teeth engage with the top plate.

[0138] Beneficial effects: The second side of the comb teeth engages with the winnowing basket, resulting in a simple structure that is easy to disassemble and install. At least two engagement points between the comb teeth and the winnowing basket enhance the structural stability of the winnowing basket and the entire winnowing basket.

Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0207] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0208] The following is combined Figures 1-33 The following describes embodiments of the present invention.

[0209] According to an embodiment of the present invention, a winnowing basket is provided, such as Figure 1 As shown, it includes: a winnowing basket 1, a rotating rod 2, and a locking assembly 3.

[0210] The scoop 1 has a scoop rim 101 at its length end, through which garbage can enter the interior of the scoop 1. One end of the rotating rod 2 is rotatably mounted on the scoop 1, allowing the rotating rod 2 to rotate relative to the scoop 1 along its length, thus placing the scoop in a folded or working state. A locking assembly 3 is driven between the scoop 1 and the rotating rod 2. The locking assembly 3 can rotate circumferentially, switching between an unlocked and a locked state. When the locking assembly 3 is in the unlocked state, the rotating rod 2 can rotate relative to the scoop 1 along its length to move closer to or further away from the scoop rim 101, thus placing the scoop in a folded state. When the locking assembly 3 is in the locked state, the rotation of the rotating rod 2 along the length of the scoop 1 is restricted.

[0211] In the above embodiment, a locking component 3 is provided between the winnowing basket 1 and the rotating rod 2. By rotating the locking component 3 in its circumferential direction, it changes between its unlocked and locked states, controlling the rotating rod 2 of the winnowing basket to be in a rotatable state and a restricted non-rotatable state, respectively. When the locking component 3 is in the unlocked state, that is, when the rotating rod 2 can rotate, the rotating rod 2 is folded to facilitate the storage of the winnowing basket. When the locking component 3 is in the locked state, that is, when the rotation of the rotating rod 2 is restricted, the position of the rotating rod 2 is kept fixed to ensure the normal operation of the winnowing basket. This solves the problem that the winnowing basket rod 5 is easily folded incorrectly during use of current foldable winnowing baskets, improving the user experience.

[0212] In this embodiment, the length direction of the winnowing basket 1 is parallel to... Figure 2 The first rotating shaft 303 in the winnowing basket shown is oriented in the same direction as the width of the winnowing basket 1. Figure 3 The first rotating shaft 303 in the winnowing basket shown in the diagram has the same orientation.

[0213] Specifically, such as Figure 2 , Figure 3 As shown, the rotating rod 2 can be used as a connector for the winnowing basket rod 5. The winnowing basket rod 5 is connected to the rotating rod 2 as an extension rod for user convenience.

[0214] This embodiment features a winnowing basket with two types of locking components 3.

[0215] The first embodiment of the winnowing basket is described below.

[0216] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 As shown, the locking assembly 3 includes a first rotating part 301 and a second rotating part 302 connected to each other. The rotating rod 2 is connected to the winnowing basket 1 through the first rotating part 301 and the second rotating part 302. The first rotating part 301 is rotatably connected to the rotating rod 2 through a first rotating shaft 303, so that the rotating rod 2 is rotatably mounted on the winnowing basket 1 and can rotate about the axis of the first rotating shaft 303 to move closer to or away from the winnowing basket edge 101, so that the winnowing basket is in a folded state. The second rotating part 302 is circumferentially rotatably connected to the winnowing basket 1, and The rotating rod 2 can rotate relative to the hopper 1 in its own circumference, so that when the rotating rod 2 rotates in its own circumference, it can drive the first rotating part 301 and the second rotating part 302 to rotate synchronously in the circumference, thereby driving the first rotating shaft 303 to rotate in the circumference, so that the locking assembly 3 rotates to the unlocked state or the locked state; when the locking assembly 3 is in the unlocked state, the axial direction of the first rotating shaft 303 is perpendicular to the length direction of the hopper 1; when the locking assembly 3 is in the locked state, the axial direction of the first rotating shaft 303 is not perpendicular to the length direction of the hopper 1.

[0217] In the above embodiment, the first rotating part 301 and the second rotating part 302 constitute the locking assembly 3. The first rotating part 301 is rotatably connected to the rotating rod 2 through the first rotating shaft 303 to facilitate the folding of the winnowing basket. The second rotating part 302 is rotatably connected to the winnowing basket 1 to allow the rotating rod 2 to rotate along its own circumference, so as to change the orientation of the first rotating shaft 303, thereby realizing the locking and unlocking of the locking assembly 3.

[0218] Specifically, in Figure 2 In the winnowing basket state shown, the axial direction of the first rotating shaft 303 is not perpendicular to the length direction of the winnowing basket 1. Figure 2 (The axis of the first rotating shaft 303 is parallel to the length direction of the hopper 1). Therefore, when the user applies force along the length of the hopper 1 to flatten the hopper edge 101, the position of the first rotating shaft 303 will interfere with the relative rotation of the rotating rod 2 and the first rotating part 301, thus achieving the locking function of the locking assembly 3 and ensuring that the hopper is not incorrectly folded. Figure 3 In the winnowing basket state shown, the axis of the first rotating shaft 303 is perpendicular to the length direction of the winnowing basket 1. When the user applies force to the length direction of the winnowing basket 1, the position of the first rotating shaft 303 will not interfere with the relative rotation of the rotating rod 2 and the first rotating part 301. That is, the locking component 3 is in the unlocked state, so that the winnowing basket can be folded freely.

[0219] It should be noted that the rotating rod 2 can be configured to rotate around the axis of the first rotating shaft 303, so that the winnowing basket can be folded whether it is close to or away from the edge 101. When the rotating rod 2 is close to the edge 101, it folds forward; when it is away from the edge 101, it folds backward.

[0220] In some embodiments, such as Figure 5 , Figure 7 , Figure 8 As shown, the winnowing basket 1 is provided with a mounting groove 102, and the second rotating part 302 is inserted into the mounting groove 102 so that the second rotating part 302 is circumferentially connected to the winnowing basket 1.

[0221] In the above embodiment, an installation groove 102 is provided in the hopper 1 so that the second rotating part 302 of the locking assembly 3 can be inserted and engaged with the installation groove 102 and rotatably installed. The structure is simple and the connection is reliable.

[0222] Specifically, when the second rotating part 302 is inserted into the mounting groove 102, the outer wall of the second rotating part 302 and the inner wall of the mounting groove 102 are in clearance fit, thereby realizing the circumferential rotational connection between the second rotating part 302 and the scoop 1.

[0223] It should be noted that the mounting groove 102 can be configured as a through groove that extends through the height of the scoop 1, or a groove formed on the upper surface of the scoop 1. This embodiment does not impose any restrictions.

[0224] In some embodiments, such as Figure 5 , Figure 7 , Figure 8 As shown, one of the second rotating part 302 and the mounting groove 102 is provided with an annular groove 3021, and the other is provided with a buckle 1021; the second rotating part 302 is inserted into the mounting groove 102, so that the buckle 1021 is engaged with the annular groove 3021, and the annular groove 3021 can rotate circumferentially relative to the buckle 1021.

[0225] In the above embodiments, the second rotating part 302 and the mounting groove 102 are circumferentially rotated through the snap-fit ​​of the annular groove 3021 and the buckle 1021, which is simple in structure and reliable in connection.

[0226] Specifically, in this embodiment, the outer wall of the second rotating part 302 is provided with an annular groove 3021, and the inner wall or bottom of the mounting groove 102 is provided with a buckle 1021. The annular groove 3021 is arranged around the entire circumference of the outer wall of the second rotating part 302, and multiple buckles 1021 are provided and are distributed circumferentially at intervals along the inner wall or bottom of the mounting groove 102.

[0227] In some embodiments, such as Figure 5 , Figure 7 , Figure 8 As shown, the mounting groove 102 is a through groove. When the second rotating part 302 is inserted into the mounting groove 102, the buckle 1021 communicates with the outside through the bottom of the through groove to facilitate adjustment of the fit between the buckle 1021 and the annular groove 3021.

[0228] In the above embodiment, the mounting groove 102 is a through groove so that the user can directly adjust the fit between the buckle 1021 and the annular groove 3021 through the bottom of the scoop 1, thereby facilitating the disassembly and assembly of the rotating rod 2.

[0229] Specifically, the mounting groove 102 is a through groove, and a buckle 1021 is provided at the bottom of the mounting groove 102 so that the buckle 1021 is located at the bottom of the hopper 1, thereby facilitating the user to adjust the buckle 1021.

[0230] In some embodiments, such as Figure 5 As shown, a one-way limiting mechanism is provided between the second rotating part 302 and the mounting groove 102 so that the second rotating part 302 can rotate unidirectionally relative to the hopper 1.

[0231] In the above embodiment, a one-way limiting mechanism is provided between the second rotating part 302 and the mounting groove 102 to control the second rotating part 302 to rotate only in one direction relative to the hopper 1, so as to avoid excessive wear between the second rotating part 302 and the inner wall of the mounting groove 102 when it is driven to rotate.

[0232] Specifically, the one-way limit mechanism can be designed as an electronic lock or a combination of ratchet and one-way groove.

[0233] In some embodiments, such as Figure 5 , Figure 8 , Figure 9 , Figure 10 As shown, the one-way limiting mechanism includes at least one-way groove 1022 and at least one limiting ratchet 3022 that cooperate with each other. One of the at least one-way groove 1022 and the at least one limiting ratchet 3022 is provided on the outer wall of the second rotating part 302, and the other is provided on the inner wall of the mounting groove 102. The second rotating part 302 rotates unidirectionally relative to the hopper 1 by the snap-fit ​​cooperation of at least one-way groove 1022 and at least one limiting ratchet 3022.

[0234] In the above embodiment, the one-way rotational engagement between the second rotating part 302 and the mounting groove 102 is achieved through the one-way rotational engagement structure of the one-way groove 1022 and the limiting ratchet 3022, which is simple in structure and reliable in connection.

[0235] Specifically, in this embodiment, the limiting ratchet 3022 is provided on the outer wall of the second rotating part 302, and the one-way groove 1022 is provided on the inner wall of the mounting groove 102.

[0236] Furthermore, two limiting ratchet teeth 3022 are arranged opposite each other along the outer circumferential direction of the second rotating part 302, and four one-way grooves 1022 are arranged along the inner circumferential direction of the mounting groove 102.

[0237] In some embodiments, such as Figure 5 , Figure 6 As shown, a limiting component is provided between the first rotating part 301 and the rotating rod 2. The limiting component can restrict the rotating rod 2 from rotating relative to the first rotating part 301 along the first rotating shaft 303, so as to fix the position of the rotating rod 2 relative to the winnowing basket 1.

[0238] In the above embodiment, by providing a limiting component between the first rotating part 301 and the rotating rod 2, the stability is improved by keeping the winnowing basket in a folded state or in a working state.

[0239] Specifically, the limiting component can be designed as an electronic lock or a mating structure of protrusions and grooves.

[0240] In some embodiments, such as Figure 5 , Figure 6, Figure 11 As shown, the limiting component includes: multiple grooves 3011 and limiting protrusions 201.

[0241] Multiple grooves 3011 are distributed circumferentially along the first rotating shaft 303 on the first rotating part 301; a limiting protrusion 201 is provided on the rotating rod 2 and can cooperate with the grooves 3011; after the rotating rod 2 rotates relative to the first rotating part 301, the limiting protrusion 201 can engage with one of the grooves 3011 to fix the position of the rotating rod 2 relative to the scoop 1.

[0242] In the above embodiment, the position of the rotating rod 2 relative to the first rotating part 301 is fixed by the snap-fit ​​of multiple grooves 3011 and limiting protrusions 201, so as to keep the winnowing basket in a folded state or in a working state. The structure is simple and the connection is reliable.

[0243] Specifically, in this embodiment, a limiting protrusion 201 is provided at the middle position of the rotating rod 2, and a plurality of grooves 3011 are provided at intervals on the outer periphery of the upper part of the first rotating part 301. After the rotating rod 2 rotates, the limiting protrusion 201 can engage with at least one of the grooves 3011.

[0244] Furthermore, three grooves 3011 are provided at intervals on the outer periphery of the top of the first rotating part 301. The three grooves 3011 are distributed at a 90° angle relative to the first rotating shaft 303 and are located at the top position and the two sides of the first rotating part 301, respectively.

[0245] Furthermore, the limiting protrusion 201 can apply force to the groove 3011 by friction or elastic deformation, thereby keeping the position of the rotating rod 2 relative to the first rotating part 301 fixed.

[0246] In some embodiments, such as Figure 11 As shown, the limiting protrusion 201 is configured as an elastic sheet protruding toward the groove 3011; or, the limiting protrusion 201 includes an elastic component.

[0247] In the above embodiments, the limiting protrusion 201 is configured as an elastic sheet or elastic component so as to apply force to the groove 3011 by means of elastic deformation, thereby ensuring the stability of the deformation and reset of the limiting protrusion 201.

[0248] Specifically, in this embodiment, the limiting protrusion 201 is set as an elastic sheet.

[0249] In some embodiments, such as Figure 1 As shown, the winnowing basket also includes a winnowing basket rod 5, which is connected to the end of the rotating rod 2 away from the winnowing basket 1.

[0250] In the above embodiment, the winnowing basket rod 5 is connected to the rotating rod 2 as an extension to facilitate user use.

[0251] In some embodiments, such as Figure 1 As shown, the winnowing basket rod 5 and the rotating rod 2 are integrally formed or detachably connected; or, the rotating rod 2 is sleeved on the outside of at least part of the winnowing basket rod 5.

[0252] In the above embodiments, the winnowing basket rod 5 and the rotating rod 2 are integrally formed to improve the structural stability of the winnowing basket; the winnowing basket rod 5 and the rotating rod 2 are detachably connected to facilitate the packaging and transportation of the winnowing basket at the factory.

[0253] Additionally, the user can drive the rotating rod 2 to rotate via the winch rod 5 to switch the locking assembly 3 between the unlocked and locked states, making it more convenient for the user. Specifically, when it is necessary to switch the locking assembly 3 between the unlocked and locked states, the user can rotate the winch rod 5 circumferentially. The winch rod 5 drives the rotating rod 2 to rotate circumferentially, and the rotating rod 2 drives the locking assembly 3 to rotate circumferentially to switch between the unlocked and locked states.

[0254] Specifically, the rotating rod 2 can be sleeved on the outside of at least part of the winnowing basket rod 5, or at least part of the winnowing basket rod 5 can be sleeved on the outside of the rotating rod 2.

[0255] In some embodiments, such as Figure 1 As shown, the winnowing basket pole 5 is configured as a multi-segment pole, and adjacent pole segments are connected by threads; when a one-way limiting mechanism is provided between the second rotating part 302 and the mounting groove 102, the direction in which the second rotating part 302 can rotate unidirectionally relative to the winnowing basket 1 is the same as the direction of the threaded connection between the pole segments.

[0256] In the above embodiment, the direction in which the second rotating part 302 can rotate unidirectionally relative to the winnowing basket 1 is the same as the direction of the threaded connection between the rods, so as to avoid the winnowing basket 5 of the multi-section rods from loosening when the second rotating part 302 rotates with the rotating rod 2 and the winnowing basket 5, and to ensure the structural stability of the winnowing basket.

[0257] Specifically, the winnowing basket rod 5 is designed as a multi-segment rod to facilitate factory packaging and transportation. The direction in which the second rotating part 302 can rotate unidirectionally relative to the winnowing basket 1 is the same as the direction of the threaded connection between the rods. When the rotating rod 2 and the winnowing basket rod 5 are rotated to drive the second rotating part 302 to rotate, the multi-segment winnowing basket rod 5 will form a tighter threaded connection and will not loosen.

[0258] In some embodiments, such as Figure 1 As shown, when the locking assembly 3 is in the locked state, the rotating rod 2 can move closer to the winnowing basket 1 relative to the winnowing basket 1 with the axis of the first rotating shaft 303 as the axis of rotation.

[0259] In the above embodiment, when the locking component 3 is in the locked state, the rotating rod 2 can move closer to the winnowing basket 1 with the axis of the first rotating shaft 303 as the axis of rotation, so that the rotating rod 2 can drive the winnowing basket rod 5 to fold towards the side of the winnowing basket 1, which is convenient for storing the winnowing basket.

[0260] Specifically, the rotating rod 2 can move closer to the winnowing basket 1 relative to the winnowing basket 1 about the axis of the first rotating shaft 303, in... Figure 1 From this perspective, the rotating rod 2 can drive the winnowing basket rod 5 to fold in the direction of the left or right sides of the winnowing basket 1.

[0261] The second embodiment of the winnowing basket is described below.

[0262] In some embodiments, such as Figure 12 , Figure 13 As shown, the winnowing basket 1 is provided with a connecting seat 103. The rotating rod 2 is rotatably connected to the connecting seat 103 through a second rotating shaft 304. The axis of the second rotating shaft 304 is perpendicular to the length direction of the winnowing basket 1, so that the rotating rod 2 is rotatably set on the winnowing basket 1 and can rotate about the axis of the second rotating shaft 304 to approach the winnowing basket edge 101, so that the winnowing basket is in a folded state. At least part of the locking component 3 is sleeved inside the rotating rod 2 and can rotate circumferentially relative to the rotating rod 2, so that the locking component 3 can switch between an unlocked state and a locked state. When the locking component 3 is in the locked state, the locking component 3 cooperates with the connecting seat 103. When the locking component 3 is in the unlocked state, the locking component 3 disengages from the connecting seat 103.

[0263] In the above embodiment, a connecting seat 103 is provided on the winnowing basket 1, and the rotating rod 2 is rotatably connected to the connecting seat 103 through the second rotating shaft 304 to facilitate the folding of the winnowing basket; at least part of the locking component 3 is sleeved inside the rotating rod 2, and the locking component 3 is used to switch between the unlocked state and the locked state by rotating circumferentially relative to the rotating rod 2; and the locking component 3 in the locked state cooperates with the connecting seat 103 to fix the position of the rotating rod 2 so that the winnowing basket can maintain its working state, and the locking component 3 in the unlocked state is disengaged from the connecting seat 103 to allow the rotating rod 2 to move freely so that the winnowing basket can be folded.

[0264] Specifically, the locking component 3 can cooperate with the inner wall of the connecting seat 103 to fix the position of the rotating rod 2.

[0265] In some embodiments, such as Figure 12 , Figure 13As shown, the locking assembly 3 includes a locking rod 305 and a locking member 306 disposed on the locking rod 305. Part of the locking rod 305 is sleeved inside the rotating rod 2, and the locking member 306 extends out of the rotating rod 2. When the locking rod 305 rotates circumferentially relative to the rotating rod 2, it drives the locking member 306 to rotate synchronously. The connecting seat 103 is provided with a mating part 1034 that cooperates with the locking member 306. When the locking assembly 3 is in the locked state, the locking member 306 and the mating part 1034 are engaged. When the locking assembly 3 is in the unlocked state, the locking member 306 and the mating part 1034 are separated.

[0266] In the above embodiments, the locking member 306 extending from the rotating rod 2 on the locking assembly 3 engages or disengages with the mating part 1034 provided on the connecting seat 103 to achieve the switching between the locked state and the unlocked state of the locking assembly 3.

[0267] Specifically, the locking member 306 is located at the bottom of the locking rod 305 or on the side wall near the bottom of the locking rod 305, so that the locking member 306 can engage or disengage with the mating part 1034 located on the connecting seat 103.

[0268] In some embodiments, the locking element 306 and the mating part 1034 constitute a first electronic lock.

[0269] In the above embodiments, the locking member 306 and the mating part 1034 are controlled by the first electronic lock to engage and disengage, thereby achieving convenient and quick electronic control.

[0270] Specifically, the first electronic lock is configured as a capacitor lock or a voltage lock.

[0271] In some embodiments, such as Figure 12 , Figure 13 As shown, the locking component 306 is a limiting block 3061 provided on the locking rod 305, and the mating part 1034 is the first side wall 1031 of the connecting seat 103; when the locking component 3 is in the locked state, the limiting block 3061 abuts against the first side wall 1031 of the connecting seat 103; when the locking component 3 is in the unlocked state, the limiting block 3061 separates from the first side wall 1031 of the connecting seat 103.

[0272] In the above embodiments, the locking component 3 is switched between locked and unlocked states by using the limiting block 3061 of the rotating rod 2 extending from the locking component 3 to cooperate or separate from the first side wall 1031 provided on the connecting seat 103.

[0273] Specifically, the limiting block 3061 protrudes from the surface of the locking member 306. The protrusion of the limiting block 3061 allows it to abut against the first side wall 1031 of the connecting seat 103, thereby locking the locking assembly 3 and restricting the rotation of the rotating rod 2. At the same time, when the limiting block 3061 is driven to rotate away from the first side wall 1031, the locking assembly 3 is unlocked, and the rotating rod 2 can rotate freely.

[0274] In some embodiments, a first opening is formed in the side wall of the rotating rod 2 in the circumferential direction, and a locking member 306 extends out of the first opening from the rotating rod 2 to engage with the mating part 1034.

[0275] In the above embodiment, a first opening is made circumferentially on the side wall of the rotating rod 2 so that the locking member 306 can extend from the side of the rotating rod 2, thereby realizing the cooperation between the limiting block 3061 on the locking member 306 and the first side wall 1031 of the connecting seat 103.

[0276] Specifically, multiple spaced transverse grooves are opened circumferentially on the side wall of the rotating rod 2 so that the limiting block 3061 on the locking member 306 can extend out of the rotating rod 2.

[0277] In some embodiments, such as Figure 12 , Figure 13 As shown, a second opening is provided at the bottom of the rotating rod 2, and the locking member 306 extends out of the second opening of the rotating rod 2, thereby engaging with the mating part 1034.

[0278] In the above embodiment, a second opening is made at the bottom of the rotating rod 2 so that the locking member 306 can extend from the bottom of the rotating rod 2, thereby realizing the cooperation between the limiting block 3061 on the locking member 306 and the first side wall 1031 of the connecting seat 103.

[0279] Specifically, the locking rod 305 passes through the rotating rod 2 so that the limiting block 3061 on the locking member 306 extends out of the rotating rod 2 through the second opening at the bottom of the rotating rod 2.

[0280] In some embodiments, such as Figure 12 , Figure 13 As shown, the bottom of the locking rod 305 is provided with a limiting flange 3051, which is arranged opposite to the rotating rod 2 to restrict the locking rod 305 from moving to the top of the rotating rod 2.

[0281] In the above embodiment, by setting a limiting flange 3051 to cooperate with the rotating rod 2 to limit the movement of the locking rod 305 to the top of the rotating rod 2, the stability of the winnowing basket is ensured.

[0282] Specifically, the limiting protrusion 3051 is arranged along the entire circumference of the locking rod 305, and it protrudes laterally outward relative to the locking rod 305.

[0283] In some embodiments, such as Figure 12 , Figure 13 , Figure 14 As shown, the locking assembly 3 also includes a limiting device, which can limit the circumferential rotation of the locking member 306 relative to the rotating rod 2.

[0284] In the above embodiment, a limiting device is used to restrict the circumferential rotation of the locking member 306 relative to the rotating rod 2 to prevent the winnowing basket from being folded incorrectly.

[0285] In some embodiments, the limiting device is configured as a second electronic lock.

[0286] In the above embodiment, the second electronic lock controls the circumferential rotation of the locking member 306 relative to the rotating rod 2, thereby achieving convenient and quick electronic control.

[0287] Specifically, the second electronic lock is configured as a capacitor lock or a voltage lock.

[0288] In some embodiments, such as Figure 12 , Figure 13 , Figure 14 As shown, the limiting device is a spring block 104 provided on the connecting seat 103. The spring block 104 can abut against the locking member 306 so that the locking member 306 abuts against the rotating rod 2 in the axial direction, thereby restricting the circumferential rotation of the locking member 306 relative to the rotating rod 2.

[0289] In the above embodiment, the static friction generated by the spring block 104 abutting against the locking member 306 restricts the circumferential rotation of the locking member 306 relative to the rotating rod 2.

[0290] Specifically, the elastic force generated by the spring block 104 is directed upward toward the locking member 306. Thus, the elastic force generated by the spring block 104 applies a vertically upward force to the locking member 306, thereby making the spring block 104 tightly abut against the bottom of the locking member 306 and generating a large static friction force to overcome the rotational force on the locking member 306.

[0291] In some embodiments, such as Figure 12 , Figure 13 , Figure 14 As shown, the outer wall of the rotating rod 2 is provided with a recessed groove 202. When the winnowing basket is in a folded state, the spring block 104 can abut against the recessed groove 202 to fix the winnowing basket in a folded state.

[0292] In the above embodiment, when the winnowing basket is folded, the recessed groove 202 on the outer wall of the rotating rod 2 and the snap-fit ​​of the spring block 104 are used to keep the winnowing basket fixed in the folded state, so as to ensure the structural stability of the winnowing basket in the storage state.

[0293] Specifically, the rotating rod 2 rotates downwards until the winnowing basket is in a folded state. At this time, the spring block 104 applies an upward force to the rotating rod 2, which causes a certain degree of interference between the rotating rod 2 and the second rotating shaft 304 and the connecting seat 103, thereby restricting the rotation of the rotating rod 2 to return to its original position.

[0294] In some embodiments, such as Figure 14 As shown, the spring block 104 includes a spring 1041 that abuts against the connecting seat 103 and extends to the locking member 306, and a spring block head 1042 disposed on the top of the spring 1041, the spring block head 1042 being able to abut against the locking member 306.

[0295] In the above embodiment, a spring 1041 is provided connected to the spring head 1042 so that the spring head 1042 can be subjected to a restoring elastic force by means of the spring 1041.

[0296] Specifically, the top of the spring block 1042 can be configured to conform to the recessed groove 202 to improve the stability of the spring block 104 in limiting the rotation rod 2.

[0297] In some embodiments, the limiting device further includes a locking mechanism disposed between the rotating rod 2 and the locking rod 305. After the locking rod 305 moves along the axial direction of the rotating rod 2 toward the direction of the hopper 1, the locking mechanism is in a disengaged state, so that the locking rod 305 can rotate circumferentially relative to the rotating rod 2.

[0298] In the above embodiment, a locking mechanism is provided so that the locking rod 305 can rotate circumferentially relative to the rotating rod 2.

[0299] In some embodiments, such as Figure 12 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown, the locking mechanism includes a locking block 3062 and an opening slot that engages with the locking block 3062. One of the locking block 3062 and the opening slot is located on the locking member 306, and the other is located on the side wall of the rotating rod 2. When the locking rod 305 moves along the axial direction of the rotating rod 2 towards the direction of the hopper 1, the locking block 3062 can separate from the opening slot, so that the locking rod 305 can rotate relative to the rotating rod 2.

[0300] In the above embodiment, by utilizing the limiting engagement and separation of the locking block 3062 and the opening slot, the locking rod 305 is fixed and rotated by a corresponding angle relative to the rotating rod 2, so as to adjust the position of the locking block 3062 and realize the rotation adjustment of the rotating rod 2 relative to the scoop 1.

[0301] Specifically, in this embodiment, the locking block 3062 is provided on the locking member 306, and the opening slot is provided on the side wall of the rotating rod 2.

[0302] In some embodiments, such as Figure 12 , Figure 15 , Figure 16 , Figure 17 , Figure 18 As shown, the opening slots include a first opening slot 203 and a second opening slot 204 distributed circumferentially along the rotating rod 2; after the locking rod 305 moves along the axial direction of the rotating rod 2 towards the direction of the winnowing basket 1, it can drive the locking member 306 to move, so that the spring block 104 is compressed and the locking block 3062 is disengaged from the first opening slot 203, so that the locking block 3062 can be rotated to the second opening slot 204 by the locking rod 305, and push the locking block 3062 to engage with the second opening slot 204 when the spring block 104 is reset.

[0303] In the above embodiment, the first opening groove 203 and the second opening groove 204 distributed circumferentially along the rotating rod 2 are respectively engaged with the locking block 3062 to facilitate changing the locking state and unlocking state of the locking component 3.

[0304] Specifically, Figure 15 , Figure 16 In the state of the locking rod 305 shown, the locking block 3062 is engaged with the two first opening slots 203 that are arranged opposite each other along the length of the scoop 1. At this time, the locking block 3062 can act as a limiting block 3061 to abut against the first side wall 1031 of the connecting seat 103, thereby preventing the rotating rod 2 from being driven to fold and keeping the scoop folded. Figure 17 , Figure 18 In the locked state shown, the locking block 3062 is engaged with the two second opening slots 204 that are arranged opposite each other along the width direction of the winnowing basket 1. At this time, the locking block 3062 is separated from the first side wall 1031 of the connecting seat 103, so that the rotating rod 2 can be driven to rotate to fold the winnowing basket.

[0305] Furthermore, since the first opening groove 203 and the second opening groove 204 are straight grooves, they can improve the locking stability. However, they can only limit the locking block 3062 and cannot change the depth of the engagement between the locking block 3062 and the groove. Therefore, when rotating the locking rod 305, it is necessary to first apply downward force along the axis of the rotating rod 2 so that the locking block 3062 can leave the first opening groove 203 or the second opening groove 204, so that the locking rod 305 can drive the locking block 3062 to adjust its rotation position.

[0306] In some embodiments, such as Figure 13 , Figure 19 , Figure 20 , Figure 21 , Figure 22As shown, the locking mechanism includes a locking block 3062 and a ratchet groove that engages with the locking block 3062. One of the locking block 3062 and the ratchet groove is located on the locking member 306, and the other is located on the side wall of the rotating rod 2. After the locking rod 305 rotates circumferentially, the locking block 3062 can be separated from the ratchet groove, so that the locking rod 305 can rotate relative to the rotating rod 2.

[0307] In the above embodiment, the locking block 3062 and the ratchet groove are used to limit the engagement and disengagement of the locking rod 305 relative to the rotating rod 2, thereby fixing and rotating the locking rod 305 relative to the rotating rod 2 by a corresponding angle. This allows for position adjustment of the locking block 3062 and rotation adjustment of the rotating rod 2 relative to the hopper 1. Furthermore, the engagement of the locking block 3062 and the ratchet groove enables unidirectional locking of the locking rod 305 relative to the rotating rod 2, preventing excessive wear between the locking rod 305 and the inner wall of the rotating rod 2 during driven rotation.

[0308] Specifically, in this embodiment, the locking block 3062 is provided on the locking member 306, and the ratchet groove is provided on the side wall of the rotating rod 2.

[0309] In some embodiments, such as Figure 13 , Figure 19 , Figure 20 , Figure 21 , Figure 22 As shown, the ratchet groove includes at least a first ratchet groove 205 and a second ratchet groove 206 distributed circumferentially along the rotating rod 2; the locking rod 305 can rotate circumferentially to drive the locking member 306 to rotate, causing the locking block 3062 to rotate and move downward along the first ratchet groove 205, and the spring block 104 compresses and causes the locking block 3062 to disengage from the first ratchet groove 205, so that the locking block 3062 can be moved to the second ratchet groove 206 by the rotation of the locking rod 305, and when the spring block 104 is reset, it pushes the locking block 3062 to engage with the second ratchet groove 206.

[0310] In the above embodiment, the first ratchet groove 205 and the second ratchet groove 206 distributed along the circumference of the rotating rod 2 are respectively engaged with the locking block 3062 to facilitate changing the folding state and working state of the winnowing basket.

[0311] Specifically, Figure 19 , Figure 20 In the state of the locking rod 305 shown, the locking block 3062 is engaged with the two first ratchet grooves 205 that are arranged opposite each other along the length of the scoop 1. At this time, the locking block 3062 can act as a limiting block 3061 to abut against the first side wall 1031 of the connecting seat 103, thereby preventing the rotating rod 2 from being driven to fold and keeping the scoop folded. Figure 21 , Figure 22In the locking state shown, the locking block 3062 is engaged with the two second ratchet grooves 206 that are arranged opposite each other along the width direction of the scoop 1. At this time, the locking block 3062 is separated from the first side wall 1031 of the connecting seat 103, so that the rotating rod 2 can be driven to rotate to fold the scoop.

[0312] Furthermore, the design of the first ratchet groove 205 and the second ratchet groove 206 utilizes the characteristics of the ratchet grooves so that when the locking rod 305 rotates, it can drive the locking block 3062 to move, thereby changing the depth of engagement between the locking block 3062 and the groove. Therefore, when the locking rod 305 rotates, the locking block 3062 can rotate along with it and leave the first ratchet groove 205 or the second ratchet groove 206 under the guidance of the ratchet groove, so that the locking rod 305 can drive the locking block 3062 to adjust its rotational position.

[0313] In some embodiments, such as Figure 12 , Figure 13 As shown, when the locking member 306 is the limiting block 3061 provided on the locking rod 305, the locking block 3062 is the limiting block 3061.

[0314] In the above embodiments, directly setting the card block 3062 as the limit block 3061 can simplify the number of structural components and save product production costs.

[0315] In some embodiments, such as Figure 12 , Figure 13 As shown, when the bottom of the locking rod 305 is provided with a limiting protrusion 3051, and the locking member 306 is a limiting block 3061 provided on the locking rod 305, the limiting protrusion 3051 is the limiting block 3061.

[0316] In the above embodiments, directly setting the limiting protrusion 3051 as the limiting block 3061 can simplify the number of structural components and save product production costs.

[0317] Furthermore, the limiting block 3061 can also be both a locking block 3062 and a limiting flange 3051, thereby further simplifying the number of structural components and saving product production costs.

[0318] In some embodiments, such as Figure 12 , Figure 13 , Figure 23 As shown, when the connecting seat 103 is provided with a spring block 104, the top of the spring block 104 is provided with a plurality of annularly arranged inclined grooves 1043, and the locking block 3062 abuts against and engages with the inclined grooves 1043.

[0319] In the above embodiment, a plurality of annular inclined grooves 1043 are provided on the top of the spring block 104, which can drive the spring block 104 to deform and compress as the locking block 3062 rotates.

[0320] In some embodiments, the winnowing basket further includes a winnowing basket rod 5, which is connected to the end of the locking assembly 3 away from the winnowing basket 1.

[0321] In the above embodiment, the winnowing basket rod 5 is connected to the rotating rod 2 as an extension rod for user convenience.

[0322] In some embodiments, the winnowing pole 5 and the locking rod 305 are integrally formed or detachably connected; or, the locking rod 305 is sleeved on the outside of at least a portion of the winnowing pole 5.

[0323] In the above embodiments, the winnowing basket rod 5 and the locking rod 305 are integrally formed to improve the structural stability of the winnowing basket; the winnowing basket rod 5 and the locking rod 305 are detachably connected to facilitate the packaging and transportation of the winnowing basket at the factory. In addition, the user can drive the rotating rod 2 to rotate through the winnowing basket rod 5 to switch the locking component 3 to the unlocked or locked state, making it more convenient for the user to use.

[0324] Specifically, the locking rod 305 may be sleeved on the outside of at least a portion of the scoop rod 5, or at least a portion of the scoop rod 5 may be sleeved on the outside of the locking rod 305.

[0325] In some embodiments, such as Figure 12 , Figure 13 As shown, the connecting seat 103 includes a first side wall 1031, and a second side wall 1032 and a third side wall 1033 connected to and opposite to the first side wall 1031. The first side wall 1031, the second side wall 1032 and the third side wall 1033 together form a receiving cavity. At least part of the rotating rod 2 is located in the receiving cavity. The two ends of the second rotating shaft 304 are rotatably connected to the second side wall 1032 and the third side wall 1033 respectively. The mating part 1034 that cooperates with the locking member 306 is set as the first side wall 1031.

[0326] In the above embodiment, the connecting seat 103 is designed as a structure in which the first side wall 1031, the second side wall 1032 and the third side wall 1033 surround and form an opening, so as to facilitate the movement of the rotating rod 2 and the installation of the second rotating shaft 304.

[0327] In some embodiments, such as Figure 12 , Figure 13 As shown, the connecting seat 103 also includes a base 1035 connected to the bottom of the first side wall 1031, the second side wall 1032 and the third side wall 1033; when the locking assembly 3 also includes a spring block 104, the spring block 104 is disposed on the base 1035.

[0328] In the above embodiment, the base 1035 is used to provide an installation position for the spring block 104.

[0329] In some embodiments, such as Figure 24As shown, the winnowing basket 1 includes the main body of the winnowing basket 1 and the mounting structure connected to the winnowing basket rod 5.

[0330] In the above embodiments, the winnowing basket 1 is designed to be detachable and modular, so that the locking component 3 can be adapted to different types of winnowing basket 1 bodies.

[0331] In some embodiments, such as Figure 25 , Figure 26 As shown, the locking component 3 has a first position and a second position. When the locking component 3 rotates between the first position and the second position, the unlocked state and the locked state of the locking component 3 can be switched. When the locking component 3 is in the first position, the locking component 3 is in the unlocked state. When the locking component 3 is in the second position, the locking component 3 is in the locked state.

[0332] Specifically, let's take the first type of winnowing basket as an example. Figure 25 From this perspective, locking component 3 is in the first position, meaning it is unlocked, and the winnowing basket rod 5 can be rotated and folded. Figure 26 From this perspective, the locking component 3 is in the second position and is locked, so the winnowing pole 5 cannot rotate.

[0333] In some embodiments, such as Figure 25 , Figure 26 As shown, the angle between the first position and the second position is 90°.

[0334] In the above embodiment, the angle between the first position and the second position is defined as 90°, so that the winnowing basket rod 5 can be located on the left or right side of the winnowing basket 1 after being folded, rather than being folded diagonally in front of or behind the winnowing basket 1, so as to facilitate the storage of the winnowing basket.

[0335] As a variable implementation, the angle between the first position and the second position is greater than 0 and not greater than 90°.

[0336] In some embodiments, such as Figure 25 , Figure 26 As shown, when the winnowing basket also includes a winnowing basket rod 5, the winnowing basket rod 5 is provided with an inclined handle 6, and the handle 6 and the winnowing basket rod 5 rotate synchronously.

[0337] In the above embodiment, the handle 6 is connected to the winnowing basket handle 5 so that the user can hold the handle 6 to use the winnowing basket.

[0338] In some embodiments, such as Figure 26 As shown, when the locking assembly 3 is in the locked state, the tilt direction of the handle 6 is the length direction of the scoop 1. Here, the tilt direction of the handle 6 is the direction in which the end of the handle 6 away from the scoop rod 5 faces.

[0339] In the above embodiment, when the locking component 3 is in the locked state, the tilt direction of the handle 6 is the length direction of the winnowing basket 1, so that the user can easily grip the handle 6 to use the winnowing basket. Figure 26 As shown, the handle 6 is tilted towards the rear of the winnowing basket 1.

[0340] In some embodiments, when the locking component 3 is in the unlocked state, the tilt direction of the handle 6 is the width direction of the hopper 1. For example... Figure 25 As shown, the handle 6 is tilted to the left of the winnowing basket 2.

[0341] In the above embodiment, when the locking component 3 is in the unlocked state, the tilting direction of the handle 6 is the width direction of the winnowing basket 1, so that when the winnowing basket rod 5 is folded and stored, the handle 6 is tilted toward the left or right side of the winnowing basket 1 to store the handle 6, thereby further reducing the space occupied by the winnowing basket.

[0342] Moreover, when the user is using the winnowing basket normally, the tilt direction of the handle 6 is the length direction of the winnowing basket 1, and the locking component 3 is in the locked state, so the winnowing basket can be used normally; when it is necessary to store the winnowing basket, the tilt direction of the handle 6 is rotated to the width direction of the winnowing basket 1, at which time the locking component 3 is also in the unlocked state, so as to store the winnowing basket.

[0343] When the user drives the locking component 3 to the unlocked and locked states via the winnowing basket handle 5, the handle 6 and the winnowing basket handle 5 rotate synchronously. Therefore, the unlocked and locked states of the locking component 3 can be driven via the handle 6. Furthermore, when the handle 6 is in the folded state (i.e., the tilt direction of the handle 6 is the width direction of the winnowing basket 1), the locking component 3 is in the unlocked state, meaning the winnowing basket 1 can be folded. When the handle 6 is in the usable state (i.e., the tilt direction of the handle 6 is the length direction of the winnowing basket 1), the locking component 3 is in the locked state, meaning the winnowing basket 1 can be used normally. Thus, when the user is folding the handle 6, the locking component 3 is unlocked, allowing the winnowing basket 1 to be folded away.

[0344] In some embodiments, such as Figure 25 , Figure 26 As shown, when the locking assembly 3 has a first position and a second position, and the angle between the first position and the second position is 90°; when the locking assembly 3 is in the first position, the tilt direction of the handle 6 is the width direction of the winnowing basket 1; when the locking assembly 3 is in the second position, the tilt direction of the handle 6 is the length direction of the winnowing basket 1.

[0345] When the locking component 3 is in the unlocked state, the handle 6 is tilted in the width direction of the winnowing basket 1, so that when the winnowing basket rod 5 is folded and stored, the handle 6 is tilted towards the left or right side of the winnowing basket 1, thereby storing the handle 6 and further reducing the space occupied by the winnowing basket.

[0346] Moreover, when the user is using the winnowing basket normally, the tilt direction of the handle 6 is the length direction of the winnowing basket 1, and the locking component 3 is in the locked state, so the winnowing basket can be used normally; when it is necessary to store the winnowing basket, the tilt direction of the handle 6 is rotated to the width direction of the winnowing basket 1, at which time the locking component 3 is also in the unlocked state, so as to store the winnowing basket.

[0347] When the user drives the locking component 5 to the unlocked and locked states via the winnowing basket handle 5, the handle 6 and the winnowing basket handle 5 rotate synchronously. Therefore, the unlocked and locked states of the locking component 5 can be driven via the handle 6. Furthermore, when the handle 6 is in the folded state (i.e., the tilt direction of the handle 6 is the width direction of the winnowing basket 1), the locking component 5 is in the unlocked state, meaning the winnowing basket 1 can be folded. When the handle 6 is in the usable state (i.e., the tilt direction of the handle 6 is the length direction of the winnowing basket 1), the locking component 5 is in the locked state, meaning the winnowing basket 1 can be used normally. Thus, when the user is folding the handle 6, the locking component 5 is unlocked, allowing the winnowing basket 1 to be folded away.

[0348] In some embodiments, such as Figure 1 , Figure 25 , Figure 26 As shown, when the winnowing basket is equipped with a winnowing basket rod 5, the winnowing basket rod 5 is located in the middle of the width direction of the winnowing basket 1.

[0349] In the above embodiment, the winnowing basket rod 5 is positioned in the middle of the width of the winnowing basket 1, ensuring balance on both sides of the basket and improving the user experience. Furthermore, as... Figure 25 As shown, when the winnowing basket handle 5 is equipped with an inclined handle 6, when the inclined handle 6 is located in the width direction of the winnowing basket 1, the inclined handle 6 can be stored in the winnowing basket 1, reducing the space occupied by the winnowing basket.

[0350] In some embodiments, such as Figure 26 As shown, when the winnowing basket is in working condition, the rotation axis of the locking assembly 3 is parallel to the axis of the rotating rod 2.

[0351] In some embodiments, such as Figure 27 As shown, the winnowing basket also includes a comb tooth part 4, which is disposed on the winnowing basket 1 and is detachably connected to the winnowing basket 1.

[0352] In the above embodiment, a comb tooth section 4 is provided on the dustpan 1 to facilitate the user to clean hair and other debris from the broom; the comb tooth section 4 is detachably connected to the dustpan 1 to facilitate factory packaging and transportation; and it is also convenient to repair and replace the comb tooth section 4.

[0353] Specifically, the comb teeth 4 and the scoop bucket 1 are detachably connected by screws or by a snap-fit ​​assembly such as a clip; or the comb teeth 4 and the scoop bucket 1 are connected by a plug and a matching plug hole.

[0354] In some embodiments, such as Figure 27 As shown, the first side of the comb tooth section 4 is provided with comb teeth 401; the second side of the comb tooth section 4 is engaged with the hopper 1. The structure is simple and easy to disassemble and install.

[0355] In some embodiments, the two ends of the comb tooth portion 4 are respectively engaged with the two sides of the scoop 1; and / or, a longitudinal limiting member is provided between the comb tooth portion 4 and the scoop 1, the longitudinal limiting member being used to limit the movement or deformation of the comb tooth portion 4 in the vertical direction.

[0356] In some embodiments, the top of the hopper 1 has a top plate 105, and the comb teeth 4 are engaged with the top plate 105.

[0357] In the above embodiments, at least two interlocking points are made between the comb teeth 4 and the winnowing basket 1 to improve the structural stability of the winnowing basket 1 and the winnowing basket as a whole.

[0358] In some embodiments, such as Figure 27 , Figure 28 , Figure 29 , Figure 30 As shown, when the top of the hopper 1 has a top plate 105, the front end of the top plate 105 has a plug-in plate, and a first snap-fit ​​member 1051 is provided on the plug-in plate; a hollow structure 402 is provided on the second side of the comb tooth part 4; a second snap-fit ​​member 4021 adapted to the first snap-fit ​​member 1051 is provided in the hollow structure 402; the plug-in plate can enter the hollow structure 402 so that the first snap-fit ​​member 1051 and the second snap-fit ​​member 4021 can be snapped together, thereby installing the comb tooth part 4 on the hopper 1.

[0359] In the above embodiment, the detachable connection between the scoop 1 and the comb 4 is achieved by the snap-fit ​​of the first snap-fit ​​member 1051 located in the top plate 105 of the scoop 1 and the second snap-fit ​​member 4021 located in the hollow structure 402 of the comb tooth section 4.

[0360] Specifically, the first snap fastener 1051 and the second snap fastener 4021 are configured as two corresponding snap fasteners that interlock with each other; along the length direction of the hopper 1 and the length direction of the comb tooth 4, the first snap fastener 1051 and the second snap fastener 4021 are respectively provided in multiple sets.

[0361] In some embodiments, such as Figure 27 , Figure 28 , Figure 29 , Figure 30 As shown, a guide part 4022 is provided inside the hollow structure 402, and a guide groove 1052 is provided at the front end of the plug-in plate; the guide part 4022 can enter the guide groove 1052 to guide the plug-in plate into the hollow structure 402. This can guide the comb part 4 and the scoop 1 to be installed and removed precisely.

[0362] In the above embodiment, the guide portion 4022 provided in the hollow structure 402 and the guide groove 1052 provided at the front end of the plug-in plate are used to guide the plug-in plate into the hollow structure 402, so as to guide the corresponding first snap-fit ​​member 1051 and second snap-fit ​​member 4021 to snap into each other.

[0363] Specifically, the plug-in plates are distributed along the front end of the top plate 105, and several notches formed thereon form multiple guide grooves 1052; the guide part 4022 is set as a partition in the hollow structure 402 corresponding to the guide groove 1052.

[0364] In some embodiments, such as Figure 27 , Figure 28 , Figure 29 , Figure 30 As shown, the guide section 4022 divides the hollow structure 402 into at least two spaces, each of which is provided with a second snap-fit ​​component 4021; the first snap-fit ​​component 1051 is provided in a one-to-one correspondence with the second snap-fit ​​component 4021. This further improves the accuracy and convenience of installation.

[0365] In the above embodiment, multiple second snap-fit ​​members 4021 are provided in the space of multiple hollow structures 402, and multiple second snap-fit ​​members 4021 are provided in one-to-one correspondence, forming multiple snap-fit ​​components between the scoop 1 and the comb tooth part 4, thereby improving the connection stability between the two.

[0366] In some embodiments, such as Figure 27 , Figure 28 , Figure 29 , Figure 30 As shown, when the top of the scoop 1 has a top plate 105, the comb tooth 4 and the top plate 105 are respectively engaged by a first engaging component and a second engaging component; the first engaging component and the second engaging component are arranged sequentially in the direction close to the rear end of the scoop 1, and the comb tooth 4 is installed above the top plate 105.

[0367] In the above embodiment, the scoop 1 and the comb tooth 4 are respectively connected by two sets of structures, namely the first snap-fit ​​component and the second snap-fit ​​component, so as to improve the connection stability of the scoop 1 and the comb tooth 4.

[0368] Specifically, the first snap-fit ​​component and the second snap-fit ​​component can be respectively configured as snap-fit ​​components, snap-hook components, snap-fit ​​platforms, snap-fit ​​posts, and other snap-fit ​​structures.

[0369] In some embodiments, such as Figure 27 , Figure 28 , Figure 29 , Figure 30As shown, the first snap-fit ​​assembly includes a first snap-fit ​​hook disposed on the top plate 105 and a first snap-fit ​​interface disposed on the comb tooth portion 4; the first snap-fit ​​hook faces the rear end of the hopper 1.

[0370] In some embodiments, the second snap-fit ​​assembly further includes a through hole 1053 disposed on the top plate 105 and a second snap-fit ​​hook 403 disposed on the comb tooth portion 4; when the comb tooth portion 4 is installed on the hopper 1, the second snap-fit ​​hook 403 passes through the through hole 1053 and snaps onto the bottom end of the top plate 105; the second snap-fit ​​hook 403 faces the rear end of the hopper 1.

[0371] In the above embodiments, the first snap-fit ​​component achieves its snap-fit ​​effect using a first snap-fit ​​hook and a first snap-fit ​​interface; the second snap-fit ​​component achieves its snap-fit ​​effect using a second snap-fit ​​hook 403 and a through hole 1053. This improves the installation stability and reliability of the comb tooth section 4.

[0372] Specifically, the first card interface is a through hole opened on the comb tooth part 4, which is engaged with the first card hook by the side wall of the through hole. The first card hook is similar in structure to the first card member 1051. The through hole 1053 is a through hole opened on the top plate 105, which is engaged with the second card hook 403 by the side wall of the through hole. The engagement of the second card hook 403 with the through hole plays a limiting role.

[0373] In some embodiments, such as Figure 31 , Figure 32 , Figure 33 As shown, a connecting member 404 is provided at the end of the comb tooth part 4, and a hook 4041 is provided on the connecting member 404; a snap-fit ​​part 106 is provided on the inner wall of the winnowing basket 1, and a first notch 1061 facing the front end of the winnowing basket 1 is provided on the snap-fit ​​part 1061; the connecting member 404 can enter the first notch 1061 so that the comb tooth part 4 can be installed on the winnowing basket 1; and when the connecting member 404 enters the first notch 1061, the hook 4041 can snap with the snap-fit ​​part 106.

[0374] In the above embodiment, the end of the comb tooth 4 is fixed by the engagement of the hook 4041 provided at the end of the comb tooth 4 with the engagement part 106 provided on the inner wall of the hopper 1. When the comb tooth 4 is subjected to pressure from above, the end of the comb tooth 4 can be prevented from deforming outward.

[0375] Specifically, two connecting parts 404 are respectively provided on both sides of the comb part 4, and each connecting part 404 is provided with a hook 4041; two locking parts 106 are correspondingly provided on the inner wall of the scoop 1, and each locking part 106 is provided with a first notch 1061 facing the front end of the scoop 1.

[0376] In some embodiments, when a longitudinal limiting member is provided between the comb tooth portion 4 and the hopper 1, the longitudinal limiting member is provided on the connecting member 404; when the connecting member 404 is located within the first notch 1061, the longitudinal limiting member is limited between the top plate 105 and the snap-fit ​​portion 106 to limit the movement or deformation of the comb tooth portion 4 in the vertical direction.

[0377] In the above embodiments, the longitudinal limiting member is used to limit the movement or deformation of the comb tooth part 4 in the vertical direction, so as to avoid excessive deformation of the comb tooth part 4 in the vertical direction and ensure the structural stability of the hopper 1.

[0378] In some embodiments, the comb teeth 4 are detachably mounted above the top plate 105, and the top plate 105 has a second notch facing the front end of the hopper 1; the connecting member 404 can simultaneously enter and exit the first notch 1061 and the second notch, and drive the longitudinal limiting member to move between the top plate 105 and the locking part 106, so that the comb teeth 4 can be mounted on the hopper 1 or disassembled.

[0379] In the above embodiment, a second notch is provided to facilitate the installation and disassembly of the comb tooth part 4 and the scoop 1, which is convenient and reliable.

[0380] In some embodiments, such as Figure 29 As shown, when a longitudinal limiting member is provided between the comb teeth 4 and the hopper 1, both ends of the comb teeth 4 have downwardly curved sections 405. The longitudinal limiting member is provided on the hopper 1. When the comb teeth 4 is installed on the hopper 1, the longitudinal limiting member is supported at the curved position of the curved section 405 to limit the vertical movement or deformation of the comb teeth 4. This effectively prevents deformation or damage to the comb teeth 4 and improves the structural stability of the hopper 1.

[0381] In some embodiments, a first plate and a second plate are provided on the side wall of the scoop 1, which are connected to each other; the first plate is perpendicular to the side wall of the scoop 1; the end of the comb tooth 401 is provided with a slot; the first plate can enter the slot and is confined within the slot, so that the end of the comb tooth 4 is engaged with the side of the scoop 1; the second plate forms a longitudinal limiting member.

[0382] In some embodiments, the scoop 1 includes a bottom plate and side plates connected to each other; the bottom plate and side plates are perpendicular to each other. This prevents the scoop 1 from deforming during use; that is, when the user presses down on the scoop with the scoop rod, the force on the scoop is not easily transmitted to the middle of the bottom wall (scoop opening), causing the middle of the bottom wall to arch upwards.

[0383] In some embodiments, a reinforcing rib is provided on the bottom plate; the reinforcing rib is provided at the opening of the hopper 1 and extends from one end of the opening of the hopper 1 to the other end, and the reinforcing rib is parallel to the cross-section of the opening of the hopper 1; this can improve the strength of the bottom plate at the opening and effectively prevent deformation of the bottom plate of the hopper 1.

[0384] In some embodiments, the center of the back side of the base plate protrudes outward from opposite sides.

[0385] In the above embodiment, the bottom plate of the winnowing basket 1 is provided with reinforcing ribs to improve the structural strength of the winnowing basket 1; the middle of the back of the bottom plate protrudes outward from both sides to overcome the deformation of the bottom plate caused by the pressure on the top of the winnowing basket 1, and to prevent the sides of the bottom plate of the winnowing basket 1 from arching upward, thereby preventing dirt from entering the bottom of the winnowing basket 1 during use and affecting the use effect. When the user presses the winnowing basket with the winnowing basket rod, the left and right sides of the winnowing basket opening deform downward, making the winnowing basket opening flat with the ground; in addition, the left and right sides of the winnowing basket opening are raised upward, which also makes it less likely for the winnowing basket to arch upward when subjected to the force of the winnowing basket rod.

[0386] In the above embodiment, the bottom plate and the side plate are perpendicular to each other to prevent the bottom plate of the hopper 1 from arching upwards during the process of the user applying pressure to the hopper opening with the hopper rod 5 to deform the hopper opening and flatten it with the ground, which would cause the hopper opening to arch upwards.

[0387] Furthermore, the bottom plate of the winnowing basket 1 is provided with reinforcing ribs to improve the structural strength of the winnowing basket 1 and prevent the bottom plate of the winnowing basket 1 from arching upwards during the process of the user applying pressure to the winnowing basket opening through the winnowing basket rod 5 to deform the winnowing basket 1 and flatten it with the ground, causing the winnowing basket opening to arch upwards.

[0388] Furthermore, the bottom plate has a central part on the back that protrudes outwards from both sides to prevent the bottom plate of the scoop 1 from arching upwards during the process of the user applying pressure to the scoop opening with the scoop rod 5 to deform the scoop 1 and flatten it with the ground.

[0389] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and such modifications and variations all fall within the scope defined by this application.
