Description

Technical Field

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

[0002] Currently, the main components of a winnowing basket are the basket itself and the handle. To facilitate user operation, the handle is typically designed to rotate relative to the basket, allowing adjustment of the handle's orientation and easier grip. However, this free rotation of the handle relative to the basket can lead to wear and loosening. Therefore, this application provides a new connection method between the basket and the handle to address these issues. Utility Model Content

[0003] In view of this, the present invention provides a winnowing basket to solve the problem that the winnowing basket rod is easily worn and loosened due to the random rotation of the winnowing basket relative to the winnowing basket.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0106] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0107] The following is combined with Figures 1-17 The following describes embodiments of the present invention.

[0108] According to an embodiment of the present invention, a winnowing basket is provided, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: a winnowing basket 1, a winnowing basket rod assembly 2, and a limiting component. Specifically, from a downward-facing perspective of the cross-section of the winnowing basket rod assembly 2, the first direction is defined as clockwise, and the second direction as counterclockwise.

[0109] The end of the winnowing basket 2 is connected to the winnowing basket 1, and the winnowing basket 2 can rotate relative to the winnowing basket 1 in a first direction; the rotation axis of the winnowing basket 2 coincides with the central axis of the winnowing basket 2; a limiting component is provided between the winnowing basket 1 and the winnowing basket 2, and the limiting component is used to restrict the winnowing basket 2 from rotating relative to the winnowing basket 1 in a second direction, the first direction and the second direction being opposite to each other.

[0110] In some embodiments, the first direction is counterclockwise and the second direction is clockwise.

[0111] In the above embodiment, a limiting component is provided between the hopper 1 and the hopper rod assembly 2 to restrict the hopper rod assembly 2 from rotating relative to the hopper 1 in a second direction, so that the hopper rod assembly 2 can only rotate in a first direction, thereby avoiding wear and loosening of the hopper rods caused by the random rotation of the hopper rod assembly 2 relative to the hopper 1, and improving the service life of the hopper.

[0112] Specifically, currently, winnowing baskets typically consist of multiple sections, assemblies 2, for convenient packaging and transportation. These sections are connected by threads for assembly. To facilitate user operation, the winnowing basket assemblies 2 are designed to rotate relative to the basket hopper 1, allowing adjustment of the handle orientation for easier grip. However, when a user attempts to rotate the winnowing basket assemblies 2 to change the handle orientation, the applied rotational force can easily loosen the threaded connections between the sections, or even cause them to detach, rendering the basket unusable. Furthermore, the freely rotating winnowing basket assemblies 2 are prone to wear. Therefore, the winnowing basket provided in this embodiment utilizes a limiting component between the basket hopper 1 and the winnowing basket assemblies 2 to achieve unidirectional rotation of the winnowing basket assemblies 2 relative to the basket hopper 1. This ensures that the sections of the winnowing basket remain secure during use and prevents friction from the freely rotating winnowing basket assemblies 2, thus improving the user experience.

[0113] Furthermore, this embodiment does not limit the specific connection method for connecting the end of the winnowing basket 2 to the winnowing basket 1. For example, a slot can be provided in the winnowing basket 1, and the winnowing basket 2 can be inserted into the slot for connection; or a protruding rod can be provided in the winnowing basket 1, and at least a portion of the winnowing basket 2 can be made into a hollow structure, and the hollow structure can be inserted into the protruding rod for connection.

[0114] In some embodiments, such as Figure 4As shown, the scoop 1 is provided with a mounting groove 101, and the scoop rod assembly 2 is inserted into the mounting groove 101; the limiting component includes a first limiting member and a second limiting member; the first limiting member is provided on the outer wall of the scoop rod assembly 2; the second limiting member is provided on the inner wall of the mounting groove 101 and can cooperate with the first limiting member to limit the rotation of the scoop rod assembly 2 relative to the scoop 1 in the second direction.

[0115] In the above embodiment, an installation groove 101 is provided in the hopper 1 so that the hopper rod assembly 2 can be inserted and fitted into the installation groove 101 and rotatably installed. The structure is simple and the connection is reliable. Through the limiting cooperation of the first limiting member and the second limiting member, the circumferential rotation cooperation between the hopper rod assembly 2 and the installation groove 101 is realized. The structure is simple and the connection is reliable.

[0116] Specifically, when the winnowing basket rod assembly 2 is inserted into the mounting groove 101, the outer wall of the winnowing basket rod assembly 2 and the inner wall of the mounting groove 101 are clearance-fitted, thereby realizing the circumferential rotational connection between the winnowing basket rod assembly 2 and the winnowing basket 1. It should be noted that the mounting groove 101 can be set as a through groove that penetrates the height direction of the winnowing basket 1, or a groove opened on the upper surface of the winnowing basket 1. This embodiment does not impose any restrictions.

[0117] Furthermore, the first and second limiting components can be respectively configured as limiting cooperation structures for the lock cylinder and lock body of the electronic lock, limiting cooperation structures for the ratchet and the slot, etc.

[0118] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 As shown, one of the first limiting member and the second limiting member is a limiting groove 102, and the other is a limiting part 201; the first circumferential end of the limiting groove 102 can limit the limiting part 201 within the limiting groove 102 to restrict the winnowing pole assembly 2 from rotating relative to the winnowing bucket 1 in the second direction; the second circumferential end of the limiting groove 102 can guide the limiting part 201 away from the limiting groove 102 so that the winnowing pole assembly 2 can rotate relative to the winnowing bucket 1 in the first direction.

[0119] In the above embodiment, the limiting groove 102 and the limiting part 201 are used to limit the limiting part 201 by the first circumferential end of the limiting groove 102, and the limiting part 201 is guided away from the limiting groove 102 by the second circumferential end of the limiting groove 102, thereby realizing the rotation of the winnowing basket 2 relative to the winnowing basket 1 in the first direction, and thus realizing the unidirectional rotation of the winnowing basket 2.

[0120] Specifically, in this embodiment, the limiting part 201 is a protruding structure disposed on the outer periphery of the scoop rod assembly 2, and the limiting groove 102 is a recessed structure disposed on the inner periphery of the mounting groove 101.

[0121] As an alternative implementation, the limiting part 201 is a protruding structure disposed on the inner wall periphery of the mounting groove 101, and the limiting groove 102 is a recessed structure disposed on the outer wall periphery of the side winch rod assembly 2.

[0122] In some embodiments, at least two limiting parts 201 are arranged sequentially along the outer circumferential direction of the hopper rod assembly 2; each limiting part 201 may be evenly or unevenly arranged on the outer circumferential wall of the hopper rod assembly 2. At least two limiting grooves 102 may be provided along the inner circumferential wall of the mounting groove 101; each limiting part 201 may cooperate with any other limiting part 201 to achieve unidirectional rotation.

[0123] Furthermore, two limiting parts 201 are arranged opposite each other along the outer circumferential direction of the scoop rod assembly 2, and four limiting grooves 102 are arranged along the inner circumferential direction of the mounting groove 101.

[0124] Furthermore, the limiting part 201 can be specifically configured as a deformable structural component such as an elastic sheet or an elastic buckle, so as to cooperate with the limiting groove 102 through the deformation of the structural component; or it can be configured as a limiting ratchet, so as to achieve unidirectional rotation through the characteristics of the ratchet.

[0125] Furthermore, the first circumferential end of the limiting groove 102 is set as the inner wall of the groove, and the inner wall is a plane to limit the limiting part 201. The second circumferential end of the limiting groove 102 is set as an inclined surface to guide the limiting part 201 away from the limiting groove 102. The inclined surface makes the cross-sectional size of the limiting groove 102 gradually increase from the bottom of the groove to the opening of the groove; that is, the inclined surface forms a guide structure to guide the limiting part 201 away from the limiting groove 102; the plane restricts the limiting part 201 from leaving the limiting groove 102; the surface of the limiting part 201 facing the first circumferential end of the limiting groove 102 is also a plane. When the limiting part 201 is located at the first circumferential end of the limiting groove 102, the plane of the limiting part 201 is in contact with the inner circumferential wall of the first circumferential end; when the limiting part 201 is located at the second circumferential end of the limiting groove 102, the inclined surface of the limiting part 201 is in contact with the inclined surface of the second circumferential end.

[0126] In some embodiments, such as Figure 6 , Figure 7 As shown, the end wall of the first circumferential end of the limiting groove 102 forms a limiting surface 1021, which is used to limit the movement of the limiting part 201 in the circumferential direction of the mounting groove 101.

[0127] In some embodiments, the end wall of the second circumferential end of the limiting groove 102 forms a guide surface 1022, which can guide the limiting part 201 away from the limiting groove 102.

[0128] In the above embodiment, the limiting surface 1021 is used to limit the movement of the limiting part 201 in the circumferential direction of the mounting groove 101, and the guiding surface 1022 can guide the limiting part 201 away from the limiting groove 102, thereby realizing the unidirectional rotation of the winnowing basket rod assembly 2.

[0129] Specifically, the limiting surface 1021 is located in the second direction, i.e., the counterclockwise direction, and the guiding surface 1022 is located in the first direction, i.e., the clockwise direction, so that the rotation of the winnowing basket rod assembly 2 in the second direction, i.e., the counterclockwise direction, is restricted by the limiting surface 1021, while the rotation in the first direction, i.e., the clockwise direction, can proceed smoothly through the guiding surface 1022, thereby realizing the unidirectional rotation of the winnowing basket rod assembly 2.

[0130] In some embodiments, such as Figure 6 , Figure 7 As shown, the limiting part 201 includes a protrusion 2011, which is adapted to the limiting groove 102; the first circumferential end of the limiting groove 102 can limit the protrusion 2011 within the limiting groove 102 to restrict the winnowing pole assembly 2 from rotating relative to the winnowing bucket 1 in the second direction; the second circumferential end of the limiting groove 102 can guide the protrusion 2011 away from the limiting groove 102 so that the winnowing pole assembly 2 can rotate relative to the winnowing bucket 1 in the first direction.

[0131] In the above embodiment, the protrusion 2011 is used as part of the limiting part 201 so that the limiting part 201 can better cooperate with the limiting groove 102 and improve the cooperation stability between structural components.

[0132] In some embodiments, such as Figure 6 As shown, the protrusion 2011 is deformable in the depth direction of the limiting groove 102, so that the protrusion 2011 can leave the limiting groove 102 through the second circumferential end of the limiting groove 102 or be limited in the limiting groove 102 by the first circumferential end of the limiting groove 102.

[0133] In the above embodiment, the protrusion 2011 can be deformed in the depth direction of the limiting groove 102 to ensure that the protrusion 2011 can smoothly leave the limiting groove 102 or be limited by the limiting groove 102.

[0134] Specifically, the protrusion 2011 can be configured as an elastic deformation structure, such as an elastic sheet, so that it can deform in the depth direction of the limiting groove 102 as the winnowing basket rod assembly 2 rotates.

[0135] Furthermore, the protrusion 2011 can be made of shape memory metal.

[0136] In some embodiments, such as Figure 6As shown, the protrusion 2011 is movable in the depth direction of the limiting groove 102, so that the protrusion 2011 can leave the limiting groove 102 through the second circumferential end of the limiting groove 102, or be limited in the limiting groove 102 by the first circumferential end of the limiting groove 102.

[0137] In the above embodiment, the protrusion 2011 is movable in the depth direction of the limiting groove 102, ensuring that the protrusion 2011 can smoothly leave the limiting groove 102 or be limited by the limiting groove 102.

[0138] Specifically, the protrusion 2011 can be configured as a protruding head that connects to the elastic deformation structure, so that the protruding head can move in the depth direction of the limiting groove 102 as the winnowing basket rod assembly 2 rotates.

[0139] Furthermore, the elastic deformation structure can specifically be a spring.

[0140] In some embodiments, such as Figure 6 As shown, the winnowing basket also includes a cantilever 3. One end of the cantilever 3 is connected to the winnowing basket rod assembly 2 or the winnowing basket 1, and the other end of the cantilever 3 is a free end. A protrusion 2011 is provided on the free end of the cantilever 3. The free end of the cantilever 3 is movable so as to drive the protrusion 2011 to move in the depth direction of the limiting groove 102.

[0141] In the above embodiment, the free end of the cantilever 3 drives the protrusion 2011 to move, thereby realizing the movement of the protrusion 2011 within the depth of the limiting groove 102.

[0142] Specifically, the cantilever 3 is configured as a deformable elastic structural component, such as a spring.

[0143] In some embodiments, such as Figure 6 , Figure 7 As shown, the limiting groove 102 is provided on the inner peripheral wall of the mounting groove 101; the side wall of the winnowing basket rod assembly 2 is provided with a through hole 202; the cantilever 3 is provided in the through hole 202, one end of the cantilever 3 is connected to the side wall of the through hole 202, and the other end is a free end.

[0144] In some embodiments, such as Figure 6 , Figure 7 As shown, the number of through holes 202 is set to two, and the two through holes 202 are arranged opposite to each other; two cantilever arms 3 are respectively arranged in the two through holes 202, and each cantilever arm 3 is provided with a protrusion 2011, and each protrusion 2011 is provided with at least one limiting groove 102; the inside of the winnowing basket rod assembly 2 is provided with an elastic structure, and the two ends of the elastic structure are respectively connected to the free ends of the two cantilever arms 3.

[0145] In some embodiments, the protrusion 2011 may be disposed at the free end of the cantilever 3; or, the protrusion 2011 may be located closer to the free end relative to the connecting end of the cantilever connecting through hole 202 sidewall. This allows the protrusion 2011 to have a larger displacement within a shorter travel range, thereby improving the service life of the cantilever.

[0146] In the above embodiment, two cantilever arms 3 are provided and connected to two protrusions 2011 respectively, so that the two protrusions 2011 cooperate with multiple limiting grooves 102 respectively, thereby improving the cooperation stability of the structural components.

[0147] In some embodiments, the number of protrusions 2011 can be set to one or more, and the number of limiting grooves 102 can also be set to one or more, with each protrusion 2011 cooperating with any limiting groove 102.

[0148] Specifically, there are two protrusions 2011 arranged circumferentially along the outer wall of the winnowing basket rod assembly 2, and four limiting grooves 102 are arranged circumferentially along the inner wall of the mounting groove 101.

[0149] In some embodiments, such as Figure 6 As shown, the elastic structure includes a spring piece 203, with both ends of the spring piece 203 connected to the free ends of the two cantilever arms 3 respectively; the two ends of the spring piece 203 are integrally connected to the free ends of the two cantilever arms 3; the spring piece 203 is an S-shaped spring piece 203. Integrating the two ends of the spring piece 203 with the free ends of the two cantilever arms 3 improves the strength of the two cantilever arms 3, further extending their service life. Furthermore, the S-shaped spring piece 203 provides better elasticity, simultaneously providing greater elastic force to both cantilever arms 3, ensuring smooth movement of the two cantilever arms 3.

[0150] In the above embodiment, the spring 203 and the two cantilever 3 are set as an integrated S-shaped spring 203, which reduces the number of spring structural components and saves production costs.

[0151] Specifically, the two ends of the S-shaped spring 203 are integrally connected to the two cantilever 3 respectively.

[0152] In some embodiments, such as Figure 6 As shown, at least one of the first limiting member and the second limiting member is set to more than two, and each first limiting member and any second limiting member can cooperate with each other; each second limiting member is arranged sequentially in the circumferential direction of the mounting groove 101; when the winnowing basket rod assembly 2 rotates relative to the winnowing basket 1 in the first direction, the first limiting member can switch between each second limiting member to limit the winnowing basket rod assembly 2 to different positions in the first direction.

[0153] In the above embodiments, multiple first and second limiting components are provided to ensure the stability of the rotation limit of the winnowing basket rod group 2 relative to the winnowing basket 1.

[0154] Specifically, the number of either the limiting part 201 or the limiting groove 102 is set to two or more, and each limiting part 201 and any limiting groove 102 can cooperate with each other; the limiting grooves 102 are arranged sequentially in the circumferential direction of the mounting groove 101; when the winnowing basket rod assembly 2 rotates relative to the winnowing basket 1 in the first direction, the limiting part 201 can switch between the various limiting grooves 102 to limit the winnowing basket rod assembly 2 to different positions in the first direction. This ensures that the position of the winnowing basket rod assembly 2 can be adjusted according to the usage scenario and user needs during the use of the winnowing basket.

[0155] In some embodiments, such as Figure 4 As shown, the winnowing basket rod assembly 2 and the winnowing basket 1 are detachably connected.

[0156] In the above embodiment, the winnowing basket rod assembly 2 and the winnowing basket 1 are detachably connected to facilitate the packaging and transportation of the winnowing basket at the factory.

[0157] In some embodiments, such as Figure 4 , Figure 5 , Figure 8 , Figure 9 As shown, the winnowing basket 1 is provided with an axial limiting member 103, and the winnowing basket rod assembly 2 is provided with a mating part 204. The axial limiting member 103 and the mating part 204 can cooperate with each other to limit the movement of the winnowing basket rod assembly 2 relative to the winnowing basket 1 in its own axial direction. Moreover, the axial limiting member 103 can rotate relative to the mating part 204, so that the winnowing basket rod assembly 2 can rotate relative to the winnowing basket 1 in a first direction. By using the axial limiting member 103, it is possible to prevent the winnowing basket rod assembly 2 from disengaging from the winnowing basket during rotation, while ensuring smooth rotation of the winnowing basket rod assembly 2 relative to the winnowing basket 1.

[0158] In the above embodiment, the axial limiting member 103 and the mating part 204 cooperate to limit the movement of the winnowing pole assembly 2 relative to the winnowing bucket 1 in its own axial direction, so as to prevent the winnowing pole assembly 2 from falling off the winnowing bucket 1, while ensuring the free rotation of the winnowing pole assembly 2 along the first direction.

[0159] Specifically, the axial limiting member 103 and the mating part 204 can be respectively configured as a limiting mating structure for the lock cylinder and lock body of the electronic lock, a limiting mating structure for the groove and the protrusion, etc.

[0160] In some embodiments, such as Figure 4 , Figure 5 , Figure 8 , Figure 9 As shown, one of the axial limiting member 103 and the mating part 204 is an annular groove and the other is a protrusion; the protrusion is rotatably disposed in the annular groove; and the annular groove and the protrusion cooperate with each other to limit the movement of the winnowing basket rod assembly 2 relative to the winnowing basket 1 in its own axial direction.

[0161] In some embodiments, the protrusion may be an annular protrusion; or it may be at least two protrusions arranged sequentially in the circumferential direction of the annular groove.

[0162] In the above embodiments, the circumferential rotation of the second rotating part 302 scoop rod assembly 2 and the scoop bucket 1 mounting groove 101 is achieved through the snap-fit ​​of the annular groove and the protrusion, which is simple in structure and reliable in connection.

[0163] Specifically, in this embodiment, the outer wall of the winnowing basket assembly 2 is provided with an annular groove, and the inner wall or bottom of the mounting groove 101 is provided with protrusions. The annular groove is arranged circumferentially along the outer wall of the winnowing basket assembly 2, and multiple protrusions are provided, which are distributed at intervals along the circumferential direction of the inner wall or bottom of the mounting groove 101. The protrusions can be evenly or unevenly arranged circumferentially in the mounting groove 101. The shape and size of each protrusion can be the same or different, as long as they can move within the annular groove.

[0164] In some embodiments, such as Figure 4 , Figure 5 , Figure 8 , Figure 9 As shown, when the hopper 1 is provided with a mounting groove 101 and the hopper rod assembly 2 is inserted into the mounting groove 101, the bottom of the mounting groove 101 has an opening; the position of the axial limiting member 103 corresponds to the position of the opening; the hopper rod assembly 2 can extend out of the mounting groove 101 through the opening so that the axial limiting member 103 and the mating part 204 can cooperate with each other; an unlocking member is provided at the opening, and the unlocking member is connected to the axial limiting member 103; driving the unlocking member can disengage the mating part 204 from the axial limiting member 103 to disassemble the hopper rod assembly 2.

[0165] In the above embodiment, the mounting groove 101 has an opening so that the user can directly adjust the fit between the axial limiting member 103 and the mating part 204 by using the locking mechanism, thereby facilitating the disassembly and assembly of the scoop rod assembly 2.

[0166] Specifically, the unlocking component is a lever, which can be used to move the axial limiting component 103, which is a boss, on the winnowing basket rod assembly 2, thereby disassembling the winnowing basket rod assembly 2.

[0167] In some embodiments, the protrusion includes protrusions arranged sequentially in the circumferential direction of the annular groove, each protrusion being provided with an unlocking element, and the unlocking element extending in a direction away from the mounting groove 101. During use, the user can intuitively and clearly see the unlocking element, thereby facilitating the disassembly of the winnowing basket rod assembly 2 through the unlocking element.

[0168] In some embodiments, such as Figure 4 , Figure 5 , Figure 8 , Figure 9 , Figure 10 As shown, the mounting groove 101 is a through groove that passes through the hopper 1 and forms an opening at the bottom of the hopper 1; the axial limiting member 103 is provided at the bottom of the hopper 1 and corresponds to the position of the opening; when an unlocking member is provided at the opening, the unlocking member is provided at the bottom of the hopper 1.

[0169] In some embodiments, the scoop 1 includes a detachably connected scoop body and a connecting structure; the connecting structure is disposed on the top of the scoop body, and a mounting groove 101 is disposed on the connecting structure, wherein the mounting groove 101 is a through groove penetrating the connecting structure and forming an opening at the bottom of the connecting structure; an axial limiting member 103 is disposed at the bottom of the connecting structure and corresponds to the position of the opening; when an unlocking member is provided at the opening, the unlocking member is disposed at the bottom of the connecting structure. When disassembly is required, the user can detach the connecting structure from the scoop body to directly see the unlocking member, thereby operating the scoop rod assembly 2 to disassemble the scoop rod assembly 2; this method allows the user to disassemble without touching the bottom of the scoop, preventing hands from getting dirty and effectively improving the user experience.

[0170] In the above embodiment, the mounting groove 101 is a through groove so that the user can directly adjust the fit between the axial limiting member 103, which is set as a boss, and the annular slot through the bottom of the scoop 1, thereby facilitating the disassembly and assembly of the scoop rod assembly 2; the scoop 1 is designed as a split, detachable unit so as to adapt to different types of scoops.

[0171] Specifically, the mounting groove 101 is a through groove, and the bottom of the mounting groove 101 is provided with an axial limiting member 103, which is a boss, so that the boss is located at the bottom of the scoop 1, thereby facilitating the user to adjust the boss. The through groove refers to the opening in the bottom of the mounting groove 101, which allows the scoop rod assembly 2 to enter from the opening of the mounting groove 101 and extend from the bottom of the groove.

[0172] In some embodiments, such as Figure 4 As shown, the winnowing basket assembly 2 includes at least two sections of bamboo, with adjacent sections connected by threads; the threaded connection direction between each section of bamboo is opposite to the first direction; and / or, the winnowing basket also includes a comb tooth section 4, which is disposed on the winnowing basket 1; and the winnowing basket assembly 2 is connected to the comb tooth section 4, and the rotation of the winnowing basket assembly 2 relative to the winnowing basket 1 in the first direction can drive the comb tooth section 4 to move; and / or, the winnowing basket also includes a handle; the handle is disposed on the side wall of the winnowing basket assembly 2; the rotation of the winnowing basket assembly 2 relative to the winnowing basket 1 in the first direction can drive the handle to rotate.

[0173] In some embodiments, when the winnowing basket 2 rotates relative to the winnowing basket 1 in a first direction, the winnowing basket 2 can be disassembled or installed.

[0174] In the above embodiment, the adjacent rod sections of the winnowing basket rod assembly 2 are threaded together, and the threaded connection direction between each rod is opposite to the first direction, so as to avoid the multiple rod sections from loosening when the winnowing basket rod assembly 2 rotates, and to ensure the structural stability of the winnowing basket; a comb tooth part 4 is provided on the winnowing basket 1 to facilitate the user to clean hair and other debris from the broom; a handle is provided to facilitate the user to hold and operate the winnowing basket.

[0180] 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.

[0181] 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.

[0182] In some embodiments, such as Figure 11 , Figure 12 , Figure 13 , Figure 14As 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.

[0183] 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.

[0184] 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.

[0185] In some embodiments, such as Figure 11 , Figure 12 , Figure 13 , Figure 14 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.

[0186] 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.

[0187] 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.

[0188] In some embodiments, such as Figure 11 , Figure 12 , Figure 13 , Figure 14 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.

[0189] 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.

[0190] In some embodiments, such as Figure 11 , Figure 12 , Figure 13 , Figure 14 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.

[0191] 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.

[0192] 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.

[0195] 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.

[0196] 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.

[0197] In some embodiments, such as Figure 15 , Figure 16 , Figure 17 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.

[0198] 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.

[0199] 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.

[0200] 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.

[0201] 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.

[0202] 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.

[0203] 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.

[0204] In some embodiments, such as Figure 13As 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 can effectively prevent the comb teeth 4 from deforming or being damaged, and improve the structural stability of the hopper 1.

[0205] 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.

[0206] 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.

[0207] 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.

[0208] In some embodiments, the center of the back side of the base plate protrudes outward from opposite sides.

[0209] 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.

[0210] Although embodiments of the present 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 present invention, and such modifications and variations all fall within the scope defined by this application.
