Description

Technical Field

[0001] This utility model relates to the field of cleaning tools, and in particular to a winnowing basket with a tooth-collecting function. Background Technology

[0002] During cleaning, broom bristles easily pick up hair, lint, and other debris. This debris is difficult to separate from the bristles and usually requires manual removal. To solve this problem, comb teeth were designed into dustpans. However, most existing dustpans have comb teeth fixedly attached to the front edge of the top plate. While these can remove hair and lint from the broom bristles, they still get tangled in the comb teeth, requiring manual cleaning and being less hygienic.

[0003] To overcome the aforementioned shortcomings, some automatic dustpans for cleaning debris from comb teeth have emerged. For example, the utility model patent with publication number CN219920994U describes a method where, when hair or other difficult-to-clean debris is entangled on the comb teeth, the operator can apply a downward vertical force to the drive component. The drive component then moves vertically downward relative to the hopper. During this movement, the roller moves downward synchronously. Since the roller initially abuts against the upper end of the inclined surface of the transmission component, and the lower end of the inclined surface is further away from the insertion hole than its upper end, the roller's downward movement pushes the transmission component towards the cleaning position via the inclined surface. This, in turn, causes the scraper to slide, allowing the insertion hole to slide from the root of the comb teeth to the tip. During this sliding process, the comb teeth are scraped and cleaned, causing the hair and other debris entangled on the comb teeth to move towards the tip and eventually fall into the opening of the hopper. After the operator removes the force applied to the drive component, the drive component resets to its initial position under the action of the first reset component, while the transmission component resets to its clearance position under the action of the second reset component. However, the above-mentioned patented technical solution uses a scraper sliding relative to the comb teeth, leaving a gap between the scraper and the cover plate, which makes it easy for debris to get stuck, causing sliding jamming.

[0004] Therefore, it is necessary to develop a winnowing basket with a tooth-collecting function to address the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide a winnowing basket with a tooth-collecting function. The toothed plate moves back and forth in a linear motion within a closed toothed plate sliding cavity, reducing the possibility of clogging and making the tooth-collecting and releasing action more flexible.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model relates to a winnowing basket with a toothed function, comprising a winnowing basket body, toothed plates, a drive seat, a cover plate, a compression spring, and a handle. A flat toothed plate sliding cavity is provided above the top plate of the winnowing basket body. The cover plate is fastened to the top opening of the toothed plate sliding cavity and encloses the toothed plates within the cavity. A comb-tooth hole, matching multiple comb teeth at the front end of the cover plate, is provided on the bottom edge of the front end of the cover plate. The top of the drive seat is connected to the lower connector at the bottom of the handle. A drive seat sliding cavity and a toothed plate seat sliding cavity are provided at the rear of the winnowing basket body. The drive seat can slide vertically back and forth within the drive seat sliding cavity. The compression spring is located within the drive seat sliding cavity and its two ends abut against the bottom plate of the drive seat sliding cavity and the bottom end of the drive seat. Two toothed plate seats are symmetrically arranged at the rear of the toothed plates. The toothed plate seats slide back and forth within the toothed plate seat sliding cavity. An oblique guide transmission mechanism is directly provided between the toothed plate seats and the drive seat.

[0008] Furthermore, the oblique guide transmission mechanism includes an arc-shaped strip hole and a sliding column head. The arc-shaped strip hole is inclinedly arranged on the toothed plate seat plate with its front bottom and rear top. A front boss is provided at the top front end of the drive seat. The two sliding columns are respectively arranged on the left and right outer walls of the front boss. The sliding columns are guided and slidably connected in the arc-shaped strip hole.

[0009] Furthermore, the horizontal cross-section of the drive seat is square, and the corresponding horizontal cross-sectional profile of the inner hole of the drive seat sliding cavity is also square; the bottom end of the drive seat is provided with a compression spring cavity to accommodate the top end of the compression spring.

[0010] Furthermore, a positioning ring is centrally located on the bottom plate of the drive seat sliding cavity, and the positioning ring limits the bottom hole of the compression spring.

[0011] Furthermore, the bottom of the cover plate is provided with two rows of clips at the front and rear, the front end of the toothed plate sliding cavity bottom plate is provided with a groove corresponding to the front row of clips, and the rear part of the toothed plate sliding cavity bottom plate is provided with a clip hole corresponding to the rear row of clips.

[0012] Furthermore, the toothed plate is provided with a plurality of spaced-apart limiting teeth on the connecting surface at the root of the comb teeth. The length of the limiting teeth is less than that of the comb teeth, and the limiting teeth can abut against the inner side wall of the bottom edge plate at the front end of the cover plate.

[0013] Furthermore, a clearance hole is provided in the center of the rear part of the cover plate, the outline of which is adapted to the horizontal cross-section of the drive seat and limits the top surface of the front boss.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This practical winnowing basket with a tooth-collecting function has a cover plate fastened to the top opening of the flat toothed plate sliding cavity, sealing off the front and rear sliding space of the toothed plate and reducing the risk of debris entering the toothed plate sliding cavity, thus avoiding jamming. Two symmetrically arranged toothed plate base plates are connected to the drive seat via the oblique guide transmission mechanism, which can stably drive the toothed plate and reduce misalignment and jamming.

[0016] Furthermore, through the cooperation of the arc-shaped slot and the sliding head, the sliding head drives the toothed plate seat to slide backward during the downward movement of the drive seat, achieving the tooth retraction action. Moreover, because the arc-shaped slot protrudes forward, the tooth retraction action is variable in speed at the same downward speed of the drive seat, with the fastest retraction speed in the middle. This impact of varying retraction speed helps to remove debris adhering to the comb teeth. By adding a compression spring cavity and a positioning ring to limit the upper and lower parts of the compression spring, it is possible to prevent the compression spring from falling off and reduce the height space occupied by installing the compression spring. By creating a clearance hole in the center of the rear of the cover plate with a contour adapted to the horizontal cross-section of the drive seat, the drive seat is prevented from detaching outward without affecting its vertical sliding. The use of two rows of locking heads connecting the locking holes ensures the connection strength between the cover plate and the bottom plate of the toothed plate sliding cavity, making it less prone to detachment. By adding limiting teeth to the connecting surface at the root of the comb teeth, a gap is left between the connecting surface at the root of the comb teeth and the inner side wall of the bottom edge of the front end of the cover plate when the comb teeth are exposed, so as to avoid trapping hair and other debris, which would be difficult to clean.

[0027] The core of this utility model is to provide a winnowing basket with a tooth-collecting function. The toothed plate moves back and forth in a linear motion within a closed toothed plate sliding cavity, which reduces the possibility of clogging and makes the tooth-collecting and releasing action more flexible.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] In one specific implementation, such as Figures 1-8 As shown, the winnowing basket with tooth-collecting function of this utility model includes a winnowing basket body 1, a toothed plate 2, a drive seat 3, a cover plate 4, a compression spring 5, and a handle 6. A flat toothed plate sliding cavity 101 is provided above the top plate of the winnowing basket body 1. The cover plate 4 is fastened to the top opening of the toothed plate sliding cavity 101 and encloses the toothed plate 2 inside the toothed plate sliding cavity 101. The toothed plate 2 can slide back and forth within the toothed plate sliding cavity 101. A comb tooth hole 402 adapted to multiple comb teeth 201 at the front end of the cover plate 4 is provided on the bottom edge plate of the front end. The comb teeth 201 and the comb tooth hole 402 are arranged one-to-one. The top end of the drive seat 3 is connected to the bottom end of the handle 6 via a lower connector 601. The lower connector 601 is connected to the pin hole 301 at the top end of the drive seat 3 via a pin. The rear of the scoop body 1 is provided with a drive seat sliding cavity 104 and a toothed plate seat sliding cavity 105. Both the drive seat sliding cavity 104 and the toothed plate seat sliding cavity 105 are open at the top, and the drive seat sliding cavity 104 is nested inside the toothed plate seat sliding cavity 105. The drive seat 3 can slide vertically back and forth within the drive seat sliding cavity 104. The compression spring 5 is disposed within the drive seat sliding cavity 104 and its two ends abut against the bottom plate of the drive seat sliding cavity 104 and the bottom end of the drive seat 3. The rear of the toothed plate component 2 is symmetrically provided with two toothed plate seat plates 202. The toothed plate seat plates 202 slide back and forth within the toothed plate seat sliding cavity 105, that is, the distance between the outer side walls of the two toothed plate seat plates 202 is adapted to the width of the toothed plate seat sliding cavity 105. The tooth plate seat 202 and the drive seat 3 are directly provided with an oblique guide transmission mechanism. The oblique guide transmission mechanism converts the up and down sliding of the drive seat 3 into the back and forth sliding of the tooth plate 2, which manifests as the comb teeth 201 performing tooth retraction and tooth extension actions relative to the comb tooth hole 402.

[0032] Specifically, such as Figure 2 As shown, the compression spring 5 is a cylindrical helical spring, and the compression spring 5 returns to the drive seat 3 upward. Except for the compression spring 5, the scoop body 1, the toothed plate 2, the drive seat 3 and the cover plate 4 are all integrally molded plastic injection parts.

[0033] By fastening the cover plate 4 onto the top opening of the flat toothed plate sliding cavity 101, the front and rear sliding space of the toothed plate 2 is sealed, reducing the risk of debris entering the toothed plate sliding cavity 101 and thus preventing jamming. The two symmetrically arranged toothed plate seat plates 202 are respectively connected to the drive seat 3 through the oblique guide transmission mechanism, which can stably drive the toothed plate 2 and reduce skewness and jamming.

[0034] In one specific embodiment of this utility model, such as Figures 2-4 , Figure 6 and Figure 7As shown, the oblique guide transmission mechanism includes an arc-shaped slot 203 and a sliding head 304. The arc-shaped slot 203 is inclined and located on the toothed plate seat 202 with its front bottom and rear top, and the protrusion of the arc-shaped slot 203 faces forward. A front boss 302 is provided at the top front end of the drive seat 3, and two sliding heads 304 are respectively provided on the left and right outer walls of the front boss 302, and the sliding heads 304 are guided and slidably connected in the arc-shaped slot 203.

[0035] Through the cooperation of the arc-shaped slot 203 and the sliding head 304, during the downward movement of the drive seat 3, the sliding head 304 drives the tooth plate seat 202 to slide backward, thereby achieving the tooth retraction action. Moreover, because the arc-shaped slot 203 protrudes forward, the tooth retraction action is variable in speed under the same downward movement speed of the drive seat 3, with the fastest tooth retraction speed in the middle. This change in tooth retraction speed is beneficial for removing debris stuck to the comb teeth 201.

[0036] Obviously, the inclined guide transmission mechanism can also employ an inclined waist-shaped hole and a sliding column head 304. The inclined waist-shaped hole is inclined at the front bottom and the rear top on the toothed plate seat 202, and the sliding column head 304 is slidably connected within the inclined waist-shaped hole. Similar simple replacement methods also fall within the protection scope of this utility model.

[0037] In one specific embodiment of this utility model, such as Figure 2 , Figure 5 and Figure 7 As shown, the horizontal cross-section of the drive seat 3 is square, and the two ends of the front side are rounded. The corresponding horizontal cross-sectional profile of the inner hole of the drive seat sliding cavity 104 is also square with rounded corners. A compression spring cavity 303 is provided on the bottom end surface of the drive seat 3 to accommodate the top of the compression spring 5.

[0038] Specifically, such as Figure 2 and Figure 5 As shown, a positioning ring post 103 is centrally located on the bottom plate of the drive seat sliding cavity 104, and the positioning ring post 103 limits the middle hole at the bottom end of the compression spring 5.

[0039] By adding a compression spring cavity 303 and a positioning ring post 103 to limit the upper and lower parts of the compression spring 5, the compression spring can be prevented from falling off, and the height space occupied by the compression spring 5 can be reduced.

[0040] Specifically, such as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, a clearance hole 401 is provided in the center of the rear part of the cover plate 4. The outline of the clearance hole 401 is adapted to the horizontal cross-section of the drive seat 3, and the bottom surface of the edge of the clearance hole 401 limits the top surface of the front boss 302.

[0041] By opening a clearance hole 401 in the center of the rear part of the cover plate 4, whose contour is adapted to the horizontal cross-section of the drive seat 3, the drive seat 3 is prevented from falling outward without affecting the vertical sliding of the drive seat 3.

[0042] In one specific embodiment of this utility model, such as Figures 3-5 and Figure 8 As shown, the bottom of the cover plate 4 has two rows of clips 403 at the front and back. The front end of the bottom plate of the toothed plate sliding cavity 101 has a groove corresponding to the front row of clips 403, and the rear end of the bottom plate of the toothed plate sliding cavity 101 has a clip hole 102 corresponding to the rear row of clips 403. Each row of clips 403 has four or more clips that are spaced apart.

[0043] Specifically, such as Figure 8 As shown, the card head 403 uses a hook head at the top of the spring tooth to connect to the card hole 102.

[0044] The use of two rows of clips 403 to connect the clip holes 102 ensures the connection strength between the cover plate 4 and the bottom plate of the toothed plate sliding cavity 101, making it less likely to fall off.

[0045] In one specific embodiment of this utility model, such as Figure 6 and Figure 8 As shown, the toothed plate 2 is further provided with several spaced-apart limiting teeth 204 on the connecting surface at the root of the comb teeth 201. The length of the limiting teeth 204 is significantly smaller than that of the comb teeth 201, and the limiting teeth 204 can abut against the inner side wall of the bottom edge plate at the front end of the cover plate 4. The end faces of both the limiting teeth 204 and the comb teeth 201 are arc surfaces.

[0046] By adding limiting teeth 204 on the root connecting surface of the comb teeth 201, a gap is left between the root connecting surface of the comb teeth 201 and the inner side wall of the bottom edge plate at the front end of the cover plate 4 when the comb teeth 201 are exposed, so as to avoid trapping hair and other debris, which would be difficult to clean.

[0047] The working principle of this utility model of a winnowing basket with a tooth-collecting function is as follows: First, the hair and debris stuck to the broom are cleaned using the exposed comb teeth 201, transferring the hair and debris onto the comb teeth 201. Then, the handle 6 is pressed, causing the drive seat 3 to slide vertically downward within the drive seat sliding cavity 104, compressing the compression spring 5. During its downward sliding, the sliding column head 304 moves downward, and under the constraint of the arc-shaped strip hole 203, it drives the tooth plate seat plate 202 to slide backward, causing the comb teeth 201 to retract into the comb tooth hole 402, thus achieving the tooth-collecting action. During this process, the hair and debris wrapped around the comb teeth 201 are blocked outside the comb tooth hole 402 and fall into the collection hopper of the winnowing basket body 1 under the action of gravity. Release handle 6, spring 5 resets, push drive seat 3 upwards to reset, slide column head 304 moves upwards, under the constraint of arc strip hole 203, drives tooth plate seat plate 202 to slide forward, comb teeth 201 protrude from comb tooth hole 402, realizing tooth output action. Finally, limit tooth 204 abuts against the inner side wall of the front bottom edge plate of cover plate 4, preventing the root connecting surface of comb teeth 201 from directly pressing against the inner side wall of the front bottom edge plate of cover plate 4. If hair and debris are still entangled on comb teeth 201, press handle 6 repeatedly several times to achieve thorough cleaning.

[0048] In summary, the winnowing basket with tooth-collecting function of this utility model, by fastening the cover plate 4 onto the top opening of the flat toothed plate sliding cavity 101, seals the front and rear sliding space of the toothed plate 2, reducing the risk of debris entering the toothed plate sliding cavity 101 and thus avoiding jamming. The two symmetrically arranged toothed plate base plates 202 are respectively connected to the drive seat 3 through the oblique guide transmission mechanism, which can stably drive the toothed plate 2 and reduce skewness and jamming. Furthermore, through the cooperation of the arc-shaped slot 203 and the sliding column head 304, during the downward movement of the drive seat 3, the sliding column head 304 drives the toothed plate base plate 202 to slide backward, realizing the tooth-collecting action. Moreover, because the arc-shaped slot 203 protrudes forward, the tooth-collecting action is variable-speed under the same downward movement speed of the drive seat 3, with the fastest tooth-collecting speed in the middle. This change in tooth-collecting speed and impact helps to remove debris adhering to the comb teeth 201. By adding a spring cavity 303 and a positioning ring post 103 to limit the upper and lower parts of the spring 5, the spring can be prevented from falling off, and the height space occupied by the spring 5 can be reduced. By opening a relief hole 401 in the center of the rear of the cover plate 4 with a contour adapted to the horizontal cross-section of the drive seat 3, the drive seat 3 is prevented from falling off without affecting its vertical sliding. The use of two rows of clips 403 to connect the clip holes 102 ensures the connection strength between the cover plate 4 and the bottom plate of the toothed sliding cavity 101, making it less likely to fall off. By adding limiting teeth 204 on the connecting surface of the root of the comb teeth 201, when the comb teeth 201 are exposed, a gap is left between the connecting surface of the root of the comb teeth 201 and the inner side wall of the bottom edge of the front end of the cover plate 4, avoiding the trapping of hair and other debris, which would be detrimental to cleaning.
