The vertical rod portion 522 is sleeved in the sleeve ring hole 1425, and the transverse head portion 521 is located in the avoiding cavity 1424. So that the right end of the support shaft 5 is axially movably coupled to the end cap 14. During assembly, the left end of the supporting shaft 5 is firstly connected to the right connecting disc 23 or is fixedly connected to the right connecting disc 23 in a secondary injection molding manner, the end cover panel 142 is clamped on the end cover main body 141, and then the anti-drop head 52 penetrates through the end cover main body 141 and is inserted into the avoiding cavity 1424, so that the installation and operation are very convenient and fast. In addition, the bowl inner cavity 1410 of the end cover main body 141 can be fully utilized to store the avoiding cavity 1424, so that the structure of the floor brush assembly is more compact. Further, a bearing 51 is arranged on the end cover main body 141, the inner diameter of the inner ring of the bearing 51 is larger than that of the transverse head 521, and the transverse head 521 can axially penetrate through the bearing 51 and the end cover main body 141 to be inserted into the escape cavity 1424. This can further facilitate the mounting operation between the support shaft 5 and the end cap 14.

As shown in fig. 11, a driving element 54 is further included, wherein the driving element 54 is configured to allow at least a portion of the end cap 14 to automatically pop out of the right sidewall aperture 130 when the end cap 14 is unseated, thereby facilitating gripping of the end cap 14. In the present embodiment, the driving element 54 is a return spring 52 fitted around the support shaft 5, and a washer 53 is further fitted around the support shaft 5, and the washer 53 is provided on the right connecting disc 23. Both ends of the return spring 52 respectively press against and act between the washer 53 and the inner ring of the bearing 51. The washer 53 and the bearing 51 can prevent the return spring 52 from directly pressing and crushing the right connecting disc 23 and the end cover 14. In addition, the structure that the return spring 52 is sleeved on the support shaft 5 not only can utilize the support shaft 5 to position the return spring 52, but also can enable the structure of the floor brush assembly to be more compact. According to the above technical solution, when the end cover 14 is positioned on the right sidewall 13, the return spring 52 is compressed and deformed to store energy, and when the end cover 14 is released from the positioning, the return spring 52 is expanded and deformed to release potential energy and push the end cover 14 to axially move to emerge out of the right sidewall hole 130. In addition, by using the escape cavity 1424, the return spring 52 can move axially without driving the floor brush body 2 in the process of driving the end cover 14 to automatically protrude out of the right sidewall hole 130, so that the load of the return spring 52 is reduced. In this manner, the driving element 54 can pre-eject the end cap 14 out of the right sidewall hole 130 before the end cap 14 is axially withdrawn by a human hand, which increases the area of the end cap 14 exposed out of the right sidewall hole 130 for the human hand to grip, so that the human hand can grip the end cap 14 more to facilitate applying an axial withdrawal force to the end cap 14.

In other embodiments, the driving element may also be another type of elastic member such as an elastic arm or a silica gel column, etc. and may be pressed between the end cap 14 and the right side wall 13. Or the driving element is a pair of magnetic members, the pair of magnetic members generate mutually repulsive magnetic acting force when approaching each other, and the pair of magnetic members are respectively arranged on the end cover 14 and the right end of the floor brush body 2, or the end cover 14 and the right side wall 13. Wherein, a pair of magnetic pieces can be both hard magnets, or one of them is a hard magnet and the other is a soft magnet. When the end cap 14 is positioned on the right sidewall, a pair of the magnetic members generate a mutually repulsive magnetic force therebetween, and when the end cap 14 is released from the position, the magnetic members disposed on the end cap 14 receive the magnetic force to carry the end cap 14 to axially move to emerge out of the right sidewall hole 130.

As shown in fig. 11, a first sleeve 231 is disposed on the right connecting plate 23, the first sleeve 231 extends axially toward the end cover 14, a second sleeve 1416 is disposed on the end cover 14, the second sleeve 1416 extends axially toward the right connecting plate 23, and the first sleeve 231 and the second sleeve 1416 are sleeved together. Thus, when the floor brush assembly is lifted up by holding the end cap 14, the weight of the floor brush main body 2 can be shared by the cooperation of the first sleeve 231 and the second sleeve 1416 and the supporting shaft 5, so as to prevent the supporting shaft 5 from being deformed by pulling and bending to affect the use.

The mop head 300 has a side-drawing type roller brush assembly structure, and the inner diameter of the right sidewall hole 130 cannot be too small to affect the passing of the main body 2 in order to insert or draw the main body 2. In order to make the floor brush body 2 contact the floor in the application, the rotation axis O2 of the floor brush body 2 needs to be arranged as close to the floor as possible, but this also results in that the lower side wall of the right side wall hole 130 is too thin and has insufficient structural strength, which is very easy to be damaged. In order to solve the above technical problem, as shown in fig. 9, the right end portion of the floor brush main body 2 is connected to the end cap 14 through the support shaft 5 so that a floor brush joint point a formed on the end cap 14 is arranged to be offset from the rotation axis O1 of the end cap 14, so that the end cap 14 can bring the right end portion of the floor brush main body 2 to revolve around the rotation axis O1 of the end cap 14 and allow part of the bristles of the floor brush main body 2 to protrude out of the outer housing 1 through the lower opening portion 104 during screwing of the end cap 14 on the right sidewall hole 130. Thus, in contrast to the manner of disposing the floor brush joint point a on the rotation axis O1 of the end cap 14, it is possible to arrange some of the bristles of the floor brush main body 2 as downward as possible and to extend out of the outer housing 1 through the lower opening portion 104, which can reserve more space for providing thickness to the lower hole wall of the right side wall hole 130. Further, the rotational axis of the power output shaft 43 is arranged offset from the rotational axis O1 of the end cover 14. In this way, it is advantageous to arrange the rotation axis of the brush body 2 installed in the brush accommodating chamber 10 in balance with the ground. In addition, the center axis O2 of the support shaft 5 overlaps with the center axis of the floor brush body 2 but is arranged offset from the rotation axis O1 of the end cap 14.

An air inlet opening part 11 with a downward opening direction is further formed in the lower portion of the outer shell 1, the air inlet opening part 11 is communicated with the floor brush accommodating cavity 10 and used for allowing external dust to enter the floor brush accommodating cavity 10 and allowing part of bristles of the floor brush main body 2 to extend out of the outer shell 1 when rotating, and the air outlet opening part 12 is further included and arranged on the partition wall 12.
