Description

Self-cleaning type comb tooth dustpan and sleeving and sweeping tool

Technical Field

The invention relates to a tool for cleaning garbage, in particular to a comb self-cleaning dustpan and a sleeving and sweeping tool.

Background

The dustpan is a tool for collecting garbage and is provided with a bucket body, and the garbage such as paper scraps, hair and the like is swept into the bucket body by a broom during cleaning. Some dustpans have comb teeth (as in patent application CN 108125641A, CN 108852206a), so that filaments such as hairs and fibers stuck on the broom can be scraped off by the comb teeth, so as to continue to clean with the broom. However, hair, fibers, etc. are often adhered to the comb teeth after being scraped off by the comb teeth, and are difficult to be thrown off along with other garbage when the garbage is dumped, and the garbage also needs to be picked off by hands, which brings inconvenience and trouble to users. At present, no dustpan or sweeping tool has been found which can automatically clean the comb teeth, particularly, can clean the comb teeth without a special cleaning operation.

Detailed Description

The invention will be further illustrated by the following specific embodiments in conjunction with the accompanying drawings:

as shown in fig. 1, 2, 3 and 4, the comb self-cleaning dustpan has a dustpan body 1, and the dustpan body 1 is surrounded by a top plate 101, a bottom plate 102, a left side plate 103 and a right side plate 104 connected to the top plate and the bottom plate, and a rear side plate 105 connected to each of the four plates, and has an opening 106 at the front side. A first comb tooth 2 is fixed on the front edge of the top plate 101, the first comb tooth 2 is formed by combining a plurality of parallel arranged racks 201, and a gap 202 is formed between every two adjacent racks. When the broom 3 is stuck with silk objects such as hair, fibers and the like in the sweeping process, the first comb teeth 2 can be combed to transfer the hair to the comb teeth, or some hair can directly fall into the dustpan body 1. The dustpan body 1 is provided with a rotating beam 4, the rotating beam 4 comprises a cross beam 401, a left side beam 402 and a right side beam 403 which are connected with two ends of the cross beam 401, wherein the left side beam 402 is hinged on the left side plate 103, and the right side beam 403 is hinged on the right side plate 104. The beam 401 is provided with the cleaning part 6, the cleaning part 6 can be combined with or separated from the first comb teeth 2, when the cleaning part 6 is combined, all parts of the cleaning part 6 are positioned in the gaps 202 of all the racks of the first comb teeth 2, when the cleaning part 6 is separated, all parts of the cleaning part 6 are separated from the gaps 202, and the separation process generally generates displacement along the length direction of the racks 201 with all the racks 201 in the first comb teeth 2, so that silk objects such as hair and the like adhered on the first comb teeth 2 can be separated. The rotating beam can rotate above the opening 106, and the first state after the rotation is that when the opening 106 faces upwards, the rotating beam 4 is positioned right above the opening 106, and at the moment, the dustpan body 1 can be lifted by carrying the handle 5 connected with the rotating beam. The second state of rotation is when the opening 106 is oriented horizontally, the rotation beam 4 is positioned above the top plate 101, and the cleaning part 6 is engaged with the first comb teeth 2. The process of switching from the second state to the first state is the process of separating the cleaning part and the first comb teeth from each other, and the cleaning part is generally separated from the tooth ends of the first comb teeth, and the hair on the first comb teeth is scraped off in the process.

In one embodiment of the present invention, the cleaning part 6 includes a supporting plate 601, an open grid 602 corresponding to each rack 201 of the first comb teeth 2 is provided on the supporting plate 601, the lattice bars 603 of the open grid 602 can be inserted into the slits 202 of the first comb teeth 2, and the open grid 602 moves along the length direction of the rack 201 and is pulled out from the end of the rack 201 during the rotation of the rotating beam 4, thereby driving the hair, fiber, etc. on the first comb teeth to fall off. In particular, the supporting plate 601 and the open grid 602 may be second comb teeth, and engage with the first comb teeth 2, so that an arc line is drawn in the gap 202 of the first comb teeth while hairs and the like on the first comb teeth are dragged to fall off during the rotation of the second comb teeth along with the rotation beam 4.

In another embodiment, the cleaning part is a grid plate 10 with rectangular or elliptical holes arranged, one side of the grid plate is fixed on the cross beam 401, each rectangular hole can be sleeved on each rack 201 of the first comb teeth during the rotation of the grid plate along with the rotating beam, and the hair, fiber and the like on the first comb teeth 2 can be taken down during the rotation of the grid plate and the rack 201.

In one embodiment, the top plate 101 and the rotating beam 4 are provided with mutually matched limiting assemblies 7, such as a clamping head, a clamping groove and the like, when the rotating beam 4 is positioned above the top plate 101, the limiting assemblies 7 can be clamped together, and the lifting handle 5 can lift the dustpan body 1 when the rotating beam keeps the position, so that the dustpan is convenient to use. With more force applied and the dustpan body secured, the swivel assembly 7 is disengaged.

In one embodiment, a return spring 8 is provided at the hinge joint of the left side beam 402 and the left side plate 103 and the hinge joint of the right side beam 403 and the right side plate 104, and when the spacing assembly 7 is separated, the return spring 8 assists the rotation beam 4 to rotate, so that the dustpan body 1 is changed from the open horizontal orientation to the open upward orientation. In the rotating process, if the rotating beam rotates too fast, the rotating beam can impact the bottom plate of the dustpan body, so that the first salient points 801 can be arranged on the left side beam and the right side beam, the second friction parts 802 are arranged on the left side plate and the right side plate, the second friction parts can be arc-shaped, and the friction force between the second friction parts and the first salient points is increased along with the rotation of the rotating beam. The first friction portion may be provided on the left and right side members, and the second protrusion may be provided on the left and right side plates.

The comb tooth self-cleaning dustpan can be combined with a broom into a complete sweeping tool.

The above embodiments are merely illustrative of the concept and implementation of the present invention, and are not restrictive, and technical solutions that are not substantially changed under the concept of the present invention are still within the scope of protection.
