When there are debris on the comb teeth 3, the comb teeth 3 are driven to make a linear motion through the transmission component, and the loosely adhered garbage can be removed under the vibration generated by the movement of the comb teeth 3 themselves;
[0027] Among them, in the above scheme, the comb teeth 3 can be moved linearly by fixing the movement direction of the rack 10 and the comb teeth 3.
[0028] Among them, see Figure 2 , Figure 3 and Figure 4In this embodiment, the dustpan 1 is in the shape of a standard dustpan with a trapezoidal side wall and a single-side opening. The edge of the top surface of the dustpan 1 extends upward or downward to form a circle of enclosure 6, and the enclosure 6 and the top surface of the dustpan 1 form a placement cavity with a top opening. Holes matching the number of comb teeth 3 are provided on the enclosure 6 on the same side as the opening of the dustpan 1 to form a tooth cleaning member 61, and the comb teeth 3 are inserted into the tooth cleaning member 61, wherein one end of the rack is fixed on the comb teeth 3, and the rack 10 is horizontally attached to the top surface of the dustpan 1, wherein a guide member 7 is provided on the top surface of the dustpan 1. The guide member 7 in the case includes two columns vertically fixed on the top surface of the dustpan 1, a connecting block is fixed on the comb teeth 3, and a guide groove 8 corresponding to the movement distance and direction of the comb teeth 3 is opened on the connecting block. The coordinated use of the guide member 7 and the guide groove 8 fixes the running direction of the comb teeth 3. In addition, a cover plate 4 is detachably connected to the placement cavity, and the cover plate 4 clamps the comb teeth 3 in the placement cavity to prevent them from detaching. The comb teeth 3 can be placed in or removed by opening the cover plate 4, and the cover plate 4 and the placement cavity can be fixed by the mutual connection of the buckle 41 and the card slot.
[0029] Among them, see Figure 3 and Figure 5 The driving part includes a vertically arranged rack 2 12 meshing with the transmission gear 11, the rack 2 12 is fixed to the lower end of the dustpan rod 2, and the dustpan bucket 1 is provided with a limiting guide part 5 to limit the movement distance and movement direction of the rack 2 12. Specifically, the limiting guide part 5 is provided with a resistance part 1, and the dustpan rod 2 is provided with a resistance part 2. When the resistance part 1 is in conflict with the resistance part 2, the dustpan rod 2 stops moving (see Figures 2 to 5 ), in the scheme discussed in this paragraph, the movement of the rack 2 can be achieved by manually pressing the dustpan rod, or a foot pedal extending horizontally to the outside of the dustpan bucket can be fixed on the bottom of the dustpan rod or the rack 2, and the reciprocating movement of the rack 2 can be achieved by stepping on the foot pedal or lifting the foot pedal;
[0030] Among them, see Figures 2 to 5 The top surface of the dustpan 1 extends downward to form an assembly cavity 9, and the rack 12 is inserted into the installation cavity and is oriented and limited by the assembly cavity 9, wherein a plurality of reinforcing ribs 91 are vertically arranged in the assembly cavity 9 to improve the strength of the assembly cavity 9, and at the same time, a clamping groove 92 for accommodating the transmission gear 11 is also arranged in the assembly cavity 9, wherein a reset spring 13 is also placed in the assembly cavity 9, one end of the reset spring 13 is in contact with the bottom surface of the assembly cavity 9, and the other end of the reset spring 13 is in contact with an end surface of the rack 12, and the force application / force receiving direction of the reset spring 13 is the movement direction of the rack 12.
[0031] Among them, a through hole is opened on the cover plate 4 for the dustpan rod 2 to be inserted, the edge of the through hole extends upward and the edge of the top opening extends toward the center to form a resistance part 1, and the limiting guide part is constituted by the part of the cover plate that forms the resistance part 1 and the assembly cavity 9. The resistance part 2 arranged on the dustpan rod 2 can slide in a directional manner in the limiting guide part 5 and cannot be separated from the limiting guide part 5 under the action of the resistance part 1.
[0032] In addition, see Figure 1 , Figure 2 The dustpan rod 2 is divided into two sections hinged to each other for easy storage, etc. The hinge points 21 of the two sections of the dustpan rod 2 are placed above the first and second contact parts to avoid affecting the function.
[0033] Working process and principle:
[0034] When the product is not in use, the tip of the comb teeth 3 may be in contact with the hole of the tooth cleaning member 61 (state one) or the root of the comb teeth 3 may be in contact with the hole of the tooth cleaning member 61 (state two). In state one, when the product is used, the dustpan rod 2 is pressed to make the rack 2 12 move in a directional manner in the installation cavity. At this time, the rack 2 12 drives the comb teeth 3 to extend out of the tooth cleaning member 61 through the transmission gear 11. After the comb teeth 3 have combed the hair on the broom, the dustpan rod is released. 2. The comb teeth 3 can be restored to their original positions under the action of the reset spring 13. During this process, the hair on the comb teeth 3 will be scraped off by the tooth cleaning member 61. At the same time, if it is under the condition of state 2, the hair on the broom will be cleaned by the comb teeth 3 first, and then the dustpan rod 2 is pressed to make the comb teeth 3 and the tooth cleaning member 61 move relative to each other to achieve the scraping of the hair on the comb teeth 3. During the above operation, the dustpan rod 2 will be affected by the limiting guide part 5 so that the entire product will not be separated.
[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structural transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, is also included in the patent protection scope of the present invention.
