A dustpan

Abstract

This application discloses a winnowing basket, including a winnowing basket, a winnowing basket rod, a comb-like component, a first connecting rod, and a second connecting rod. The winnowing basket has a forward-facing opening, with a cleaning component positioned along the upper edge of the opening. The lower end of the winnowing basket rod is movably connected to the winnowing basket and can slide vertically. The comb-like component slides on the winnowing basket, with a portion extending through the cleaning component. The two ends of the first connecting rod are rotatably connected to the lower end of the winnowing basket rod and the comb-like component, respectively. The two ends of the second connecting rod are rotatably connected to the winnowing basket and the first connecting rod, with its rotatable connection to the first connecting rod located between two other rotatable connections of the first connecting rod. When the winnowing basket rod is pressed down, it causes the first connecting rod to move downward, causing the second connecting rod to swing downward, which in turn causes the first connecting rod to retract the comb-like component from outside the cleaning component, allowing the cleaning component to remove debris from the comb-like component.

Description

Technical Field

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

[0002] In daily life and work, a dustpan is a cleaning tool used in conjunction with a broom to collect trash. During cleaning, trash and other debris are typically swept into the dustpan's container using a broom, and then transferred to a trash can. Because brooms usually have dense bristles at the bottom, they easily trap hair, debris, and other impurities. Current designs often incorporate comb-like teeth along the upper edge of the dustpan's opening; sweeping the broom bristles over these teeth supposedly removes the debris. However, this fixed-teeth design tends to transfer bristles to the teeth themselves, failing to actually solve the problem of debris sticking.

[0003] To address this, existing technology provides a solution where a mesh-like cleaning block is placed along the upper edge of the sieve, and then the comb teeth pass through the cleaning block. When the comb teeth and the cleaning block are relatively displaced, the debris adhering to the comb teeth can be removed. However, the existing cleaning method has a relatively complex drive and movement structure, which is prone to damage, resulting in high production and usage costs. Utility Model Content

[0004] This application aims to at least partially solve the problem that the comb-tooth cleaning structure on existing winnowing baskets is too complex, resulting in high production and usage costs. To this end, this application provides a winnowing basket, comprising:

[0005] A winnowing basket having a forward-facing opening and a cleaning element disposed at the upper edge of the opening;

[0006] The winnowing basket handle is movably connected at its lower end to the winnowing basket and can slide vertically relative to the winnowing basket.

[0007] The comb teeth are slidably disposed on the scoop and can partially protrude from the cleaning component;

[0008] The first connecting rod is rotatably connected at both ends to the lower end of the winnowing rod and the comb tooth component, respectively.

[0009] The second connecting rod is rotatably connected at both ends to the winnowing basket and the first connecting rod, respectively.

[0010] The rotatable connection between the second link and the first link is located between the first link and the lower end of the sieve rod and the rotatable connection of the comb teeth. This allows the first link to move downward when the sieve rod is pressed down, which in turn causes the second link to swing downward relative to the sieve. This causes the first link to rotate relative to the comb teeth and retract the comb teeth from the cleaning component, so that the cleaning component can clean the debris on the comb teeth.

[0011] In some embodiments, the first link is composed of a first sub-link, a second sub-link, and a third sub-link connected in sequence, so that the first link is in the shape of a "Z".

[0012] In some embodiments, the rotatable connection points between the first connecting rod and the lower end of the winnowing basket rod, the second connecting rod and the comb teeth are respectively located on the first sub-rod, the second sub-rod and the third sub-rod.

[0013] In some embodiments, the scoop is formed as a shell with an opening on the front side, an upper top shell, and an internal support layer that engages with the side wall of the scoop. The comb teeth are slidably disposed on the support layer and located between the support layer and the upper top shell.

[0014] In some embodiments, the inner wall of the hopper is provided with supporting ribs, and the rear part is a rear side wall. The support layer is supported on the supporting ribs and is engaged with the rear side wall.

[0015] In some embodiments, a return spring is provided between the comb teeth and the support layer, and the return spring stores force when the comb teeth retract from the cleaning component.

[0016] In some embodiments, a sliding guide structure is provided between the scoop and the scoop rod, so that the scoop rod can slide vertically relative to the scoop.

[0017] In some embodiments, the sliding guide structure includes a slider at the lower end of the winnowing basket and a groove at the rear of the winnowing basket that slides with the slider. The slider has a square cross-section in the horizontal direction, and the shape of the groove is adapted to the slider.

[0018] In some embodiments, the scoop rod includes a main rod connected above the slider, and the sliding guide structure further includes a guide hole located above the groove, through which the main rod passes, the shape of the guide hole being adapted to the shape of the main rod.

[0019] In some embodiments, the winnowing basket further includes a rear cover, which is provided on the rear part of the rear side wall when the winnowing basket is formed as a shell with an opening on the front side and a rear side wall. Attached Figure Description

[0042] This application is described below with reference to the accompanying drawings and specific embodiments:

[0043] This application discloses a winnowing basket with an innovative mechanical linkage structure that enables efficient cleaning of debris by the comb teeth, solving the problems of debris easily sticking to the comb teeth and the complex cleaning structure in existing winnowing basket designs. Figure 1 , 2As shown, the winnowing basket mainly consists of a basket 1, a basket handle 2, and a comb-like component 3. The basket 1, serving as the main load-bearing structure, is shaped like a shell with an opening 11 on the front. This shell design effectively accommodates various collected debris, preventing it from falling during cleaning. A cleaning component 12 is located at the upper edge of the opening 11. The comb-like component 3 is slidably mounted on the basket 1 and consists of multiple parallel comb teeth spaced at appropriate intervals, allowing each tooth to pass through the cleaning component 12. When hair, fibers, or other easily entangled debris becomes entangled on the comb-like component 3, driving the portion of the comb-like component 3 that extends beyond the cleaning component 12 retracts it from the outside of the cleaning component 12. The debris entangled on the comb-like component 3 is then blocked by the cleaning component 12. Since the cleaning component 12 is located at the upper edge of the opening 11, the debris, once blocked by the cleaning component 12, falls directly into the basket 1, creating a very convenient and efficient structure.

[0044] The winnowing basket handle 2 is the main gripping component for the user to operate the winnowing basket. It is generally made of lightweight aluminum alloy, which is not only lightweight, making it convenient for users to hold and operate for extended periods, but also has high strength and is not easily bent or deformed. In this solution, as... Figure 3 , 4As shown, the cooperation between the winnowing basket rod 2, the first connecting rod 4, and the second connecting rod 5 enables the winnowing basket rod 2 to also drive the comb teeth 3 to retract from the outside of the cleaning component 12. Firstly, the lower end of the winnowing basket rod 2 is movably connected to the winnowing basket 1, allowing it to slide vertically relative to the winnowing basket 1. Secondly, both ends of the first connecting rod 4 are rotatably connected to the lower end of the winnowing basket rod 2 and the comb teeth 3, respectively. This allows the comb teeth 3 to move when the winnowing basket rod 2 moves downwards via the first connecting rod 4. Since the first connecting rod 4 also moves downwards when the winnowing basket rod 2 moves downwards, the comb teeth 3 tends to move downwards. The comb teeth 3 only needs to retract into the cleaning component 12 to complete the cleaning of debris. Therefore, in this design, the second connecting rod 5 is also provided to restrict the movement of the first connecting rod 4. That is, both ends of the second connecting rod 5 are connected to the winnowing basket 1 and the first connecting rod 4, respectively. 4. A rotatable connection is made, and the rotatable connection between the second link 5 and the first link 4 is located between the first link 4 and the lower end of the winnowing rod 2 and the rotatable connection of the comb tooth 3. This causes the second link 5 to swing downward as the first link 4 moves downward with the winnowing rod 2, thereby causing the rotatable connection between the first link 4 and the comb tooth 3 to move inward. That is, the rotatable connection between the first link 4 and the lower end of the winnowing rod 2 moves in the vertical direction, and the first link 4 as a whole swings relative to its rotatable connection with the lower end of the winnowing rod 2. This causes the first link 4 to rotate relative to the comb tooth 3 and drive the comb tooth 3 to retract from the outside of the cleaning component 12, so that the debris on the comb tooth 3 can be cleaned by the cleaning component 12. The arrangement of the first link 4 and the second link 5, along with the winnowing rod 2, forms a transmission structure that accurately transmits motion to drive the comb teeth 3. It can change the direction and magnitude of the force transmission, so that when the winnowing rod 2 moves downward, the comb teeth 3 can be accurately driven to retract through the synergistic action of the first link 4 and the second link 5. This design is simpler than similar structures in existing designs and transmits motion more accurately, thereby saving production and usage costs.

[0045] Furthermore, such as Figure 5 As shown, the first connecting rod 4 is composed of a first sub-rod 41, a second sub-rod 42, and a third sub-rod 43 connected sequentially in a "Z" shape. This "Z" shaped structure was derived through multiple mechanical simulations and experimental optimizations. It enables motion transmission between components within the limited internal space of the hopper 1, avoiding interference between components, while maximizing the space available for collecting debris in the hopper 1. The first sub-rod 41, the second sub-rod 42, and the third sub-rod 43 are manufactured using a one-piece molding process, resulting in high strength at the connection points, capable of withstanding the forces generated by multiple motion transmissions.

[0046] Specifically, such as Figure 4 , 5As shown, the pivots at the ends of the first sub-rod 41 and the third sub-rod 43 are rotatably engaged with the lower end of the scoop rod 2 and the rear of the comb tooth 3, respectively. This ensures that during the downward movement of the scoop rod 2, the comb tooth 3 can be driven to move via the first connecting rod 4, thus realizing the motion transmission between the scoop rod 2 and the comb tooth 3. With the cooperation of the second connecting rod 5, the vertical movement of the scoop rod 2 is converted into the horizontal sliding of the comb tooth 3. The pivot holes at both ends of the second connecting rod 5 are also rotatably engaged with the second sub-rod 42 and the pivot on the scoop 1, respectively. The second sub-rod 42 is located between the first sub-rod 41 and the third sub-rod 43. That is, the rotatable connection between the second connecting rod 5 and the first connecting rod 4 is located between the first connecting rod 4 and the rotatable connection between the lower end of the scoop rod 2 and the comb tooth 3. This specific positional design is the key to the entire motion mechanism. It can change the direction of movement of the first connecting rod 4, so that when the scoop rod 2 moves downward, the comb tooth 3 can be accurately driven to retract through the synergistic action of the first connecting rod 4 and the second connecting rod 5.

[0047] In another embodiment of this utility model, such as Figure 6 , 7 As shown, the hopper 1 is formed into a shell shape with an opening 11 on the front side, and its upper part is a top shell 14. The top shell 14 not only seals and protects the upper part of the hopper 1, but also cooperates with the internal structure to provide installation space for other components. Specifically, the hopper 1 has a support layer 13 that engages with the side wall. The support layer 13 has good load-bearing capacity. The comb teeth 3 are slidably mounted on the support layer 13 and located between the support layer 13 and the top shell 14. The support layer 13 has a sliding track that matches the comb teeth 3. The track surface is smooth, which reduces the friction when the comb teeth 3 slides, allowing the comb teeth 3 to slide smoothly on the support layer 13. Through the arrangement of the top shell 14 and the support layer 13, the comb teeth 3 are protected in the space between the support layer 13 and the top shell 14, thereby minimizing the contamination of the comb teeth 3 by debris and ensuring its smooth movement.

[0048] Furthermore, such as Figure 6 , 7 As shown, the inner wall of the winnowing basket 1 is provided with supporting ribs 15, which are integrally formed with the winnowing basket 1. On the one hand, this enhances the overall structural strength of the winnowing basket 1, and on the other hand, it provides a stable load-bearing foundation for the support layer 13. The rear part of the winnowing basket 1 is the rear side wall 16, and the support layer 13 is connected to the rear side wall 16 through a snap-fit ​​structure. This connection method ensures that the support layer 13 is firmly installed and will not loosen or shift during the use of the winnowing basket, thus ensuring the stable operation of subsequent components.

[0049] In addition, such as Figure 8As shown, a return spring 6 is provided between the comb teeth 3 and the support layer 13. The return spring 6 has good elasticity and durability. One end of the return spring 6 is fixedly connected to the bottom of the comb teeth 3, and the other end is fixed to the support layer 13, forming a tension spring. When the comb teeth 3 retracts from the cleaning component 12, the return spring 6 is stretched and stores force; when the external force disappears, the return spring 6 can quickly retract to release the elastic force, and spring the comb teeth 3 back to the initial position, realizing automatic reset without manual operation by the user, thus improving the convenience of use.

[0050] In another embodiment of this utility model, such as Figure 6 , 7 As shown, the lower end of the winnowing basket pole 2 is movably connected to the winnowing basket 1 via a sliding guide structure, enabling it to slide vertically. Specifically, the winnowing basket pole 2 includes a main pole 22 and a slider 21 connected to the lower end of the main pole 22. The sliding guide structure consists of two parts: one part is the slider 21 at the lower end of the winnowing basket pole 2, which has a square cross-section in the horizontal direction; the other part is a groove 17 at the rear of the winnowing basket 1 that slides and engages with the slider 21. The shape of the groove 17 is adapted to the slider 21. The square slider 21 engaging with the groove 17 effectively restricts the rotation of the winnowing basket pole 2 during sliding, ensuring that the winnowing basket pole 2 can only slide smoothly vertically, avoiding operational inconvenience caused by rotation. Furthermore, the sliding guide structure also includes a guide hole 18 located above the groove 17, through which the main pole 22 passes. The shape of the guide hole 18 is adapted to the shape of the main pole 22. The guide hole 18, in conjunction with the main rod 22 and the slider 21, in conjunction with the groove 17, forms a dual guiding function, further improving the stability and precision of the scoop rod 2's sliding motion, making it smoother and easier for the user to press down on the scoop rod 2. Through the vertical sliding of the scoop rod 2, the user can control whether the comb teeth 3 retracts into the cleaning component 12, thus selecting the cleaning of the comb teeth 3 as needed. Furthermore, the return spring 6, through the coordinated action of the first link 4 and the second link 5, ensures that the scoop rod 2 remains in a high position, thereby maintaining relative stability of all components of the scoop when the comb teeth 3 is not needed, thus guaranteeing a superior user experience.

[0051] In addition, such as Figure 7 As shown, the winnowing basket 1 is also equipped with a rear cover 19. When the winnowing basket 1 is a shell-shaped structure with an opening at the front and a rear side wall 16 at the rear, the rear cover 19 is placed over the rear of the rear side wall 16. The rear cover 19 uses a snap-on connection, which is convenient for disassembly and installation. Its main function is to protect the internal structures of the winnowing basket 1, such as connecting rods and sliders, to prevent dust, moisture, etc. from entering the interior and affecting the service life of the components. It also makes the appearance of the winnowing basket cleaner and more aesthetically pleasing.

[0052] When actually using the winnowing basket, such as Figure 3 , 4In the initial state, the comb teeth 3, under the action of the return spring 6, partially protrudes from the cleaning component 12 and enters the working state. This allows hair, fibers, and other debris on the broom to be scraped off by the comb teeth 3 and left on the comb teeth 3. When a lot of debris is entangled on the comb teeth 3, affecting the cleaning effect, the user only needs to press down on the dustpan rod 2. The dustpan rod 2 moves smoothly downward under the guidance of the slider 21, the groove 17, the guide hole 18, and the main rod 22, driving the first connecting rod 4 to move downward synchronously. The downward movement of the first connecting rod 4 causes the second connecting rod 5 to swing downward relative to the dustpan 1. Due to the specific connection position between the second connecting rod 5 and the first connecting rod 4, the first connecting rod 4 rotates relative to the comb teeth 3 under the action of the second connecting rod 5, causing the rotational connection between the first connecting rod 4 and the comb teeth 3 to translate horizontally, thereby pulling the comb teeth 3 to slide into the dustpan 1 and retract from the outside of the cleaning component 12, i.e. Figure 9 , 10 During the retraction of the comb teeth 3, the cleaning component 12 comes into contact with the comb teeth 3, thoroughly cleaning off the debris, which falls into the hopper 1.

[0053] After cleaning, the user releases the pressure on the dustpan handle 2, the return spring 6 releases its elasticity, and pulls the comb teeth 3 to slide outward. The comb teeth 3 drives the first connecting rod 4 and the second connecting rod 5 to reset. At the same time, the dustpan handle 2 also slides upward back to its initial position under the action of the connecting rods. The comb teeth 3 then emerges from the cleaning component 12 again, ready for the next cleaning.

[0054] In summary, this winnowing basket, through the careful design and ingenious coordination of a small number of parts, achieves the function of automatic cleaning and resetting of the comb teeth. It is convenient to operate and efficient in cleaning during use, which can effectively improve the user experience and has significant practical value and beneficial effects.
