[0045] Beneficial effects: When the hopper is opened, it drives the comb structure to switch to the second working state, allowing garbage and other materials in the hopper to be discharged through the hopper. When the comb structure returns to its closed state, it also drives the hopper to return to its closed state, realizing the linkage between the hopper and the comb. No additional operation is required from the user on the hopper or the comb, making it more convenient and intelligent to use.

[0046] Furthermore, the opening and closing of the hopper opening can drive the comb structure to move in a direction parallel to the bottom plate of the hopper, so that the comb structure can rotate, thereby enabling the comb structure to switch between the first working state and the second working state.

[0047] Beneficial effects: Integrating the comb's drive mechanism with the winnowing basket's opening and closing mechanism eliminates the need for additional complex components such as motors and springs, reducing the number of parts and assembly difficulty.

[0050] Beneficial effects: By splitting the top plate of the hopper into a movable first top plate and a second top plate, and by driving the state switching of the comb structure through the relative movement of the two, the transmission logic and structural synergy are further optimized, and the transmission stability and control accuracy are improved.

[0051] Furthermore, the hopper is also equipped with an installation plate; the installation plate is rotatably connected to the comb structure; a second top plate is disposed between the installation plate and the first top plate; and a pushing part is provided on the second top plate. When the first top plate moves relative to the second top plate, the first top plate drives the installation plate to move in a direction parallel to the bottom of the hopper, so that the pushing part can drive the comb structure to rotate, thereby enabling the comb structure to switch from the first working state to the second working state.

[0052] Beneficial effects: The multi-stage linkage design formed by the mounting plate, the second top plate pushing part and the comb tooth structure further optimizes the force transmission path and structural coordination.

[0053] Furthermore, in the first working state, the comb structure is located in front of the first top plate and the second top plate; when the first top plate moves relative to the second top plate in the first direction, the first top plate drives the comb structure to move in the first direction, while the second top plate drives the comb structure to rotate to the second working state; when the first top plate continues to move in the first direction, it drives the comb structure in the second working state to move in the first direction; the first direction is the direction parallel to the bottom plate of the hopper.

[0054] Beneficial effects: The comb structure is designed to move, rotate, and move again in a continuous motion along the first top plate in the first direction (parallel to the bottom plate), which further enhances the synergy between function switching and the working process.

[0075] 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.

[0076] The following is combined Figures 1 to 13 The following describes embodiments of the present invention.

[0077] This utility model discloses a winnowing basket, including a basket 1, a basket rod 2, and a drive mechanism 3. The basket 1 has a basket opening 111. The basket rod 2 is disposed on the basket 1. The drive mechanism 3 is movably disposed on the basket rod 2. The drive mechanism 3, moving on the basket rod 2, can drive the opening and closing of the basket opening 111. By using the drive mechanism 3, which is movably disposed on the basket rod 2, to drive the opening and closing of the basket opening 111, the structure is simple, easy to operate, and convenient to use.

[0078] In some embodiments, the drive mechanism 3 can move axially or circumferentially on the winnowing basket rod 2.

[0079] In some embodiments, the drive mechanism 3 can be a slider, button, wrench, or other structure; for example, the drive mechanism 3 is connected to the winnowing basket 1 via a pull rod inside the winnowing basket rod 2 to drive the opening and closing of the winnowing basket opening 111.

[0080] This application also discloses some embodiments in which the winnowing basket can be used to hold materials, such as grains, sand, or garbage, or any other materials.

[0081] This application also discloses some embodiments in which the sieve opening 111 can be an outlet or an inlet 112, or the same sieve opening 111 can serve as both an inlet and an outlet.

[0082] This application also discloses some embodiments in which the opening and closing of the sieve opening 111 can be achieved by driving the cover at the sieve opening 111 to slide or rotate.

[0083] This application also discloses some embodiments in which the hopper opening 111 can be provided at least one of the side, top or bottom of the hopper 1; it can be on any surface of the side.

[0084] This application also discloses some embodiments in which the drive mechanism 3 (such as a slider, button, knob, grip switch, etc.) is directly mounted on the dustpan handle 2. When the user holds the dustpan handle 2, they can control the opening and closing of the dustpan opening 111 through natural hand movements (such as pushing the slider with the thumb or pressing the switch with the finger), without having to bend over or adjust the hand position. For example, when sweeping, holding the handle and pushing the drive mechanism 3 will automatically open the dustpan opening 111; when emptying the garbage, the opposite operation will close the dustpan opening 111 to prevent the garbage from spilling. The entire process does not require taking your hands off the handle, reducing redundant movements.

[0085] This application also discloses some embodiments in which the drive mechanism 3 can be flexibly designed according to the material (such as plastic, metal) and shape (straight rod, curved rod) of the winnowing basket rod 2 (such as the slider being adapted to the straight rod, and the rotary switch being adapted to the curved rod). In the later maintenance, the damaged drive components (such as the broken connecting rod or the worn slider) can be replaced separately, without the need to replace the entire winnowing basket, thus reducing the cost of use.

[0086] Furthermore, by "moving" the control function of the dustpan opening 111 to the dustpan handle 2, this application achieves a balance between ease of operation and structural durability. It is both ergonomic (reducing bending over and saving effort) and expands the applicability of the dustpan in complex scenarios, making the cleaning process more efficient and easier.

[0087] This application also discloses some embodiments in which the winnowing basket rod 2 is movably disposed on the winnowing basket 1; the winnowing basket rod 2 has a first position and a second position relative to the winnowing basket 1, and the winnowing basket rod 2 is movable between the first position and the second position; when the winnowing basket rod 2 is in the first position, the winnowing basket opening 111 is normally open or normally closed; when the winnowing basket rod 2 is in the second position, the drive mechanism 3 can drive the winnowing basket opening 111 to open and close.

[0088] When the winnowing basket rod 2 is in the first position, the winnowing basket opening 111 remains in a fixed state of "normally open" or "normally closed," eliminating the need for continuous operation relying on the drive mechanism 3 and significantly simplifying repetitive high-frequency actions. "Normally open" means that the winnowing basket opening 111 remains in the open state, and "normally closed" means that the winnowing basket opening 111 remains in the closed state.

[0089] The dustpan opening 111 is always open: suitable for continuous cleaning for a long time (such as cleaning a large area of ​​the ground and collecting scattered garbage). Users do not need to hold the drive mechanism 3 to keep the opening open. They only need to push the dustpan handle 2 to keep the dustpan opening 111 always open, reducing the continuous force applied to the drive mechanism 3 by the hand and reducing fatigue.

[0090] The hopper opening 111 is normally closed: suitable for the garbage transfer or collection stage. The hopper opening 111 is closed to prevent garbage from spilling during the process. At this time, there is no need to manually control the drive mechanism 3. The hopper can be kept closed simply by fixing the position of the hopper rod 2, thus avoiding garbage falling due to loosening of the hand.

[0091] When the winnowing basket handle 2 is switched to the second position, the drive mechanism 3 resumes the opening and closing control of the winnowing basket opening 111, which is suitable for scenarios that require frequent adjustment of the opening and closing state.

[0092] This application also discloses some embodiments in which the winnowing basket rod 2 is rotatably mounted on the winnowing basket 1; the angle between the winnowing basket rod 2 and the bottom plate 152 of the winnowing basket 1 is different in the first position and the second position; the winnowing basket rod 2 is rotatable between the first position and the second position. This application achieves position switching by adjusting the angle between the winnowing basket rod 2 and the bottom plate 152 through rotation, which makes the relative angle between the winnowing basket rod 2 and the winnowing basket 1 ergonomically adapted and reduces operator fatigue.

[0093] This application also discloses some embodiments in which, when the winnowing basket rod 2 is in the first position, the winnowing basket rod 2 is perpendicular to the bottom plate 152 of the winnowing basket 1;

[0094] This application also discloses some embodiments in which, when the winnowing basket rod 2 is in the second position, the winnowing basket rod 2 is parallel to the bottom plate 152 of the winnowing basket 1.

[0095] In some embodiments, the angle difference matches different operating postures: for example, the hopper opening 111 is the outlet, which is set at the bottom of the hopper 1; and the hopper 1 has an inlet 112 on the side.

[0096] At this point, the angle between the winnowing basket handle 2 and the base plate 152 directly determines the user's body posture when holding it:

[0097] If the angle of the first position is small (e.g., 30°-45°): the winnowing basket handle 2 is closer to the winnowing basket 1, and the user can lift the entire winnowing basket to save space in the vertical direction. Moreover, the garbage can be discharged from the winnowing basket opening 111 at the bottom of the winnowing basket 1 by lifting the winnowing basket only a small distance.

[0098] If the angle of the second position is large (e.g., 60°-90°): the dustpan handle 2 is raised upwards, the grip point is higher, and it is suitable for standing operation. The user can easily control the dustpan without bending over and sweep the ground garbage into the dustpan opening 111.

[0099] In some embodiments, the angle difference matches different operating postures: for example, the hopper opening 111 is set on the side of the hopper 1, and the hopper opening 111 simultaneously carries in and out garbage.

[0100] At this point, if the angle of the first position is small (e.g., 30°-45°): the dustpan handle 2 is closer to the dustpan 1, and the overall center of gravity is low, making it suitable for cleaning close to the ground (such as cleaning tile grout lines and low spaces under furniture). At this time, the user can bend over slightly and let their arms hang naturally, allowing the dustpan 1 to reach into narrow areas more easily, avoiding the "can't reach" problem caused by the handle being too high.

[0101] If the angle of the second position is large (e.g., 60°-90°): the dustpan handle 2 is raised upwards, the grip point is higher, making it suitable for standing operation or dumping garbage. Users can easily control the dustpan without bending over, which is especially suitable for cleaning large areas of the ground (reducing the pressure on the lower back from continuous bending over) or dumping garbage into high garbage cans (such as kitchen upright garbage cans), making it more user-friendly for the elderly, pregnant women, and other people with weaker physical strength.

[0102] This application also discloses some embodiments in which the drive mechanism 3 can move axially in the winnowing basket rod 2 to drive the winnowing basket opening 111 to open and close; the axial sliding of the drive mechanism 3 conforms to the natural hand movement and can improve the user experience.

[0103] This application also discloses some embodiments in which, when the winnowing basket rod 2 has a first position and a second position relative to the winnowing basket 1, the drive mechanism 3 and the winnowing basket rod 2 are relatively stationary when the winnowing basket rod 2 moves between the first position and the second position; this can prevent the winnowing basket opening 111 from opening and closing due to accidental contact.

[0104] This application also discloses some embodiments in which the drive mechanism 3 includes a drive cylinder 31, which is sleeved on the outside of the winnowing basket pole 2. The close fit design of the drive cylinder 31 to the pole body is more ergonomic and provides a better user experience. Furthermore, the user does not need to specifically position the drive mechanism 3 during use, allowing for blind operation, further improving the user experience. In addition, the cylindrical structure distributes the force, reducing the risk of deformation.

[0105] This application also discloses some embodiments in which, when the driving mechanism 3 includes a driving cylinder 31, the winnowing pole 2 and the winnowing hopper 1 are rotatably connected by a rotating structure 4, so that the winnowing pole 2 can move between a first position and a second position; a clearance groove 311 is provided on the outer wall of the driving cylinder 31; when the winnowing pole 2 moves between the first position and the second position, the rotating structure 4 can enter and exit the driving cylinder 31 through the clearance groove 311; when the winnowing pole 2 rotates between the first position and the second position, the winnowing pole 2 rotates synchronously with the driving cylinder 31, and the rotating structure 4 includes an arc-shaped rotating component, the center of which is provided with a shaft hole, which is connected to the winnowing pole 2 through a rotating shaft, and the driving cylinder 31 is provided with a clearance groove 311 so that it can rotate synchronously with the winnowing pole 2.

[0106] In this embodiment, when the winnowing basket rod 2 moves between the "first position" and the "second position" (e.g., switching between working state and storage state), the movement relationship of each component is as follows:

[0107] The winnowing basket rod 2 moves as a whole relative to the rotating structure 4 (and the winnowing basket 1);

[0108] The motion trajectory of the rotating structure 4 will pass through the area of ​​the drive cylinder 31, and the clearance groove 311 on the drive cylinder 31 just matches this trajectory;

[0109] When the winnowing basket rod 2 is in the first position, the rotating structure 4 may be partially or completely located inside the drive cylinder 31;

[0110] When the winnowing basket rod 2 moves to the second position, the rotating structure 4 "passes out" of the drive cylinder 31 through the clearance groove 311; conversely, when returning from the second position to the first position, the rotating structure 4 "passes in" of the drive cylinder 31 through the clearance groove 311.

[0111] The key to this design is that the shape and position of the positioning groove 311 are strictly matched with the movement trajectory of the rotating structure 4, ensuring that there is no jamming or collision when it enters and exits the drive cylinder 31.

[0112] In this embodiment, the relative rotation of the winnowing basket rod 2 and the winnowing basket 1 is achieved through the rotating structure 4, while the clearance groove 311 avoids interference between the rotating structure 4 and the drive cylinder 31, allowing the winnowing basket rod 2 to switch smoothly between the two positions.

[0113] This application also discloses some embodiments in which, when the winnowing basket rod 2 is in the second position, the rotating structure 4 is movable in the relief groove 311 so that the driving cylinder 31 can move on the winnowing basket rod 2, thereby driving the winnowing basket opening 111 to open and close; when the winnowing basket rod 2 is in the second position, the movement of the rotating structure 4 in the relief groove 311 (such as small-angle rotation, sliding along the groove) can "make room" for the movement of the driving cylinder 31, so that the driving cylinder 31 can move smoothly on the winnowing basket rod 2.

[0114] This application also discloses some embodiments in which, when the winnowing basket rod 2 is in the second position, the drive cylinder 31 can extend one end of the winnowing basket rod 2 to open and close the winnowing basket opening 111.

[0132] This application also discloses some embodiments, in which a comb structure 142 is provided on the winnowing basket 1; the comb structure 142 has a first working state parallel to the bottom plate 152 of the winnowing basket 1 and a second working state perpendicular to the bottom plate 152 of the winnowing basket 1; the opening and closing of the winnowing basket opening 111 enables the comb structure 142 to switch between the first working state and the second working state. The comb structure 142 switches between the two states by opening and closing the winnowing basket opening 111, resulting in a simple structure and convenient operation.

[0133] In some embodiments, when the hopper opening 111 is open, the comb structure 142 can be driven to switch to a second working state, so that while the outlet is open, the garbage in the hopper 1 is driven towards the outlet through the comb structure 142. When the hopper opening 111 is closed, the comb structure 142 switches to a first working state, so that when loading garbage, the comb can clean cleaning tools such as brooms.

[0134] Furthermore, the comb structure 142 moves toward the direction of the sieve opening 111 to compress the waste and drive the waste to be discharged through the sieve opening 111.

[0136] This application also discloses some embodiments in which the opening and closing of the hopper opening 111 can drive the comb structure 142 to move in a direction parallel to the bottom plate 152 of the hopper 1, so that the comb structure 142 rotates, thereby enabling the comb structure 142 to switch between a first working state and a second working state. This driving method has a simpler structure and lower cost.

[0137] This application also discloses some embodiments in which the comb assembly 14 includes a mounting plate 141 and a comb structure 142, and teeth 143 are provided on the comb structure 142.

[0138] This application also discloses some embodiments in which the top plate 151 of the hopper 1 includes a first top plate 1511 and a second top plate 1512 that are movably disposed, and a comb structure 142 is fixedly disposed on the first top plate 1511; the first top plate 1511 can move relative to the second top plate 1512 to drive the comb structure 142 to move in a direction parallel to the bottom plate 152 of the hopper 1, so that the second top plate 1512 can drive the comb structure 142 to rotate, thereby enabling the comb structure 142 to switch from a first working state to a second working state;

[0139] When the hopper 1 includes a front hopper 121 and a rear hopper 122 that are connected to each other, the top plate 151 of the rear hopper 122 forms a first top plate 1511, and the top plate 151 of the front hopper 121 forms a second top plate 1512.

When the first top plate 1511 moves relative to the second top plate 1512, the first top plate 1511 drives the mounting plate 141 to move in a direction parallel to the bottom of the hopper 1, so that the pushing part 15121 can drive the comb structure 142 to rotate, thereby enabling the comb structure 142 to switch from a first working state to a second working state. This can effectively achieve the driving of the comb structure 142.

[0142] Furthermore, the edge of the second top plate 1512 is provided with a flange, which forms a pushing part 15121.

[0143] Furthermore, the flange of the second top plate 1512 is an arc-shaped flange, which makes the driving of the comb structure 142 more gentle.

[0144] This application also discloses some embodiments. In the first working state, the comb structure 142 is located in front of the first top plate 1511 and the second top plate 1512. When the first top plate 1511 moves relative to the second top plate 1512 in a first direction, the first top plate 1511 drives the comb structure 142 to move in the first direction, while the second top plate 1512 drives the comb structure 142 to rotate to the second working state. When the first top plate 1511 continues to move in the first direction, it drives the comb structure 142 in the second working state to move in the first direction. The first direction is parallel to the bottom plate 152 of the hopper 1.

[0145] The process of using the winnowing basket in this application is as follows:

[0146] Initial position: The winnowing basket rod 2 is in the vertical direction. At this time, the guide on the movable frame 5 is on the front bucket 121 and located at one end of the guide rail 13; at this time, the comb teeth are in the first working state; the winnowing basket opening 111 is closed; as Figure 1 As shown.

[0147] Operation 1: The user rotates the scoop rod 2, which drives the movable frame 5 to rotate, causing the guide to move to one end of the rear bucket 122; at this time, the comb teeth are in the first working state; the scoop opening 111 is closed; as... Figure 2 As shown. During the process from the initial position to operation one, the front bucket 121, the rear bucket 122, and the comb assembly 14 are relatively stationary and do not generate relative movement; and the scoop rod 2 and the drive cylinder 31 are relatively stationary, and both rotate around the rotating structure 4 at the same time, causing the rotating structure 4 to extend out of the clearance groove 311.

[0148] Operation 2: The user pushes the drive cylinder 31, which in turn moves the movable frame 5. The movable frame 5 then moves the guide component, pushing the rear bucket 122 backward. As the rear bucket 122 moves backward, it causes the winnowing basket assembly to move backward, opening the winnowing basket opening 111. Simultaneously, this causes the flange drive comb structure 142 of the front bucket 121 to rotate to the second working state, such as... Figure 4 As shown. During this process, the comb teeth can push the garbage in the hopper 1 backward so that it can be discharged from the hopper opening 111. Continue to push the drive cylinder 31, so that the comb teeth continue to move backward, and the hopper opening 111 gradually opens wider.
