Detailed Description
The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the invention easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the invention.
The first embodiment is as follows:
referring to fig. 1-3, this embodiment is a turbofan reverse resistance type hair blocking structure, which is used in cooperation with a hair collecting member, and includes at least two hair blocking portions 1 sequentially connected along a circumferential direction, where each hair blocking portion 1 includes a hair guiding region 11 and a hair reflowing region 12, an end of the hair guiding region 11 close to the hair collecting member is a first end portion 111, an end of the hair guiding region 11 far away from the hair collecting member is a second end portion 112, an end of the hair reflowing region 12 close to the hair collecting member is a third end portion 121, an end of the hair reflowing region 12 far away from the hair collecting member is a fourth end portion 122, and the second end portion 112 is disposed adjacent to the fourth end portion 122.
Preferably, the hair holding part 1 of the present embodiment is provided in plural numbers, and is connected end to end in the circumferential direction, and the hair-return region 12 located at the head end is connected to the hair-introduction region 11 located at the tail end. After the hairs inside the hair accumulating housing move towards the hair blocking structure close to the turbofan reverse resistance, the hairs can hit the hair-return area 12 and move to the hair accumulating part again. The junction of the second end 112 and the fourth end 122 is a rounded corner, so that the hair can be bent back conveniently.
The turbofan reverse resistance type hair blocking structure of the embodiment further comprises a connecting end 3 and a cover edge 41, wherein the connecting end 3 is used for arranging the hair blocking part 1, at least one part of the cover edge 41 is located outside the hair blocking part 1, and the difference between the radial length of the inner side wall of the cover edge 41 and the radial length of the hair blocking part 1 is not more than 1 mm. Thus, the hair blocking part 1 prevents the hair from passing through the gap between the connecting tip 3 and the cover rim 41 and is deflected back to the hair collecting member. The turbofan reverse-resistance type hair blocking structure of the present embodiment further includes a cover plate 42 connected to the cover rim 41.
At the end of the connecting tip 3 remote from the hair gathering member, two first flanges 31 are provided, which are arranged concentrically and in the circumferential direction. Two second retaining edges 421 arranged in the circumferential direction are provided on the surface of the cover plate 42 on the side close to the hair-gathering means, and the second retaining edges 421 can be staggered and concentrically arranged with respect to the first retaining edges 31. Thus, even a small amount of hair passes through the gap between the connecting tip 3 and the cover rim 41, the blocking structure formed by the first blocking rim 31 and the second blocking rim 421 cannot be formed alternately. The first retaining edge 31 and the second retaining edge 421 of the present embodiment are in clearance fit and have a distance of 1.5mm, so that the first retaining edge 31 and the second retaining edge 421 form a serpentine channel, and hair cannot pass through. Therefore, even if hair enters the passage between the first retaining edge 31 and the second retaining edge 421, the hair cannot pass through the passage, and thus the hair can be prevented from passing through the passage.
The cover rim 41 and the cover plate 42 in this embodiment are an integral connection, i.e. the end cover 4 in fig. 3. It is obvious that the cover rim 41 and the cover plate 42 may be formed as a single piece, and it is only necessary to ensure that the cover rim 41 is provided outside the connecting tip 3, so that, when the connecting tip 3 rotates with the hair collecting member, even if the hairs move toward the gap between the ends of the connecting tip 3 and the cover rim 41, the hairs are blocked by the hair blocking portion 1 and folded back. The cover plate 42 can be disposed on other structures opposite to the connection terminal 3, and only the second blocking edge 421 disposed to cooperate with the first blocking edge 31 is disposed on the cover plate 42.
Example two:
referring to fig. 4 and 5, the present embodiment is different from the first embodiment in that it employs a connection cap 7 instead of the end cap 4 of the first embodiment, and a connection head 6 instead of the connection tip 3 of the first embodiment, and the hair blocking part 1 of the present embodiment is disposed on the connection cap 7. The connection cover 7 of the present embodiment is provided with a connection edge extending toward the hair collecting element, and the hair blocking portion 1 of the present embodiment is provided on the inner side surface of the connection edge. When the connecting head 6 of the present embodiment and the connecting tip 3 of the first embodiment rotate in the same direction, the hair blocking part 1 of the present embodiment is inclined in the opposite direction to the first embodiment, so that the hair can be sufficiently blocked and stopped by the hair blocking part 1. At least one third stop 71 is provided on the surface of the cover body of the connecting cover 7 adjacent to the hair-gathering members. At least one fourth stop edge 61 is provided on the side of the connection head 6 close to the connection cover 7, and the fourth stop edge 61 can be staggered and concentrically arranged with the third stop edge 71.
Example three:
this embodiment is a floor brush, which includes the turbofan reverse resistance type hair blocking structure of the first embodiment.
The floor brush of the present embodiment includes a floor brush housing (not shown), a floor brush roller 8 is disposed in the floor brush housing, and bristles are disposed on the floor brush roller 8, so that hairs can be wound around the floor brush roller 8, and the floor brush roller 8 corresponds to the hair collecting member of the first embodiment. The two ends of the floor brush rolling body 8 are provided with plugs 9 and further comprise a cover 10, the plugs 9 can rotate relative to the cover 10, and the turbofan reverse resistance type hair blocking structure is arranged on the inner surface of the cover 10 or the outer surface of the plugs 9.
A rotating shaft 13 is further disposed in the middle of the floor brush roller 8 of this embodiment, the rotating shaft 13 penetrates the cover 10, a turbofan reverse resistance type hair blocking structure is also disposed at the end of the rotating shaft 13, and an outer cover (not shown) is further disposed corresponding to the outer side of the end of the rotating shaft 13. Therefore, by arranging the turbofan reverse resistance type hair blocking structure at the position of the plug 9 and the cover 10 and at the position of the tail end of the rotating shaft 13 and the outer cover body, the hairs can be effectively prevented from being drilled out through the gaps at the structural connection positions of the two ends of the scrubbing brush roller 8, and the hairs can be effectively prevented from entering the driving mechanism and being wound on the shaft of the driving motor.
Example four:
the present embodiment is a floor brush, which includes the turbofan reverse resistance type hair blocking structure of the second embodiment. The difference between the floor brush of the present embodiment and the floor brush of the third embodiment is that the turbofan reverse resistance type hair blocking structure is disposed on the inner surface of the edge of the end cover 4, so that when the floor brush roller 8 rotates, the hair is blocked by the hair blocking portion 1 and rolls on the floor brush roller 8 again, and the hair is effectively prevented from entering and winding on the shaft of the driving motor.
Example five:
the embodiment is a dust collector which comprises the floor brush in the third embodiment.
Example six:
the embodiment is a dust collector which comprises the floor brush of the fourth embodiment.
The above embodiments are merely illustrative of the technical concept and features of the present invention, and the present invention is not limited thereto, and any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
