Position spring 11, release key 10 have the key face 10b for finger push, and protruding portion is to have a face inclined-plane 10ab, face directly on one side
The grab 10a of 10aa faces the axial monodisplacement of 10aa limitation round brush 4 directly.As shown in figure 9, inclined-plane 10ab is installed towards round brush 4
When push-in direction, inclined-plane 10ab plays the role of not influencing the push-in of round brush 4, when bearing block 4 and inclined-plane 10ab are contacted, release
The meeting constriction distance under the cooperation of reset spring 11 of key 10, allows round brush 4 to be smoothly packed into.10aa is faced directly to dismantle towards round brush 4
When ejection direction, face 10aa directly and block detent slot 16, limitation bearing block 5, round brush 4 pop up outward.
Beneficial effect by adopting the above technical scheme is：Release key 10 can control the pop-up of round brush 4, when round brush 4 was installed
When in journey, the inclined-plane 10ab of release key 10 makes release key 10 not play interference effect to round brush 4, installs round brush 4 smoothly.
In other embodiments of the invention, round brush 4 has bristle 17, and the radius size of bearing block 5 is not less than rolling
Brush 4 axis to the top of bristle 17 length.
Beneficial effect by adopting the above technical scheme is：Bearing block 5 and round brush 4 pop up together, the diameter width of bearing block 5
The space for having given bristle 17 to pop up, bristle 17 will not interfere with other positions, so that pop-up resistance is small, ejection process is smooth.
In other embodiments of the invention, bearing block 5 and round brush 4 are covered with round brush lid 14, as shown in fig. 7, rolling
Has notch on brush lid 14, key face 10b is pierced by from notch.Round brush lid 14 have for round brush 4 dismounting across hole, hole
The cross-sectional profiles of profile and bearing block 5 coincide, i.e., as shown in figure 15, bearing block 5, bearing cap 8 are major arc arch, bearing block
5, bearing cap 8 is provided with a burnishing surface 20.
Beneficial effect by adopting the above technical scheme is：The non-circular major arc arch hole of round brush lid 14 and bearing cap 8
Cross-sectional profiles coincide because position of the release key 10 on round brush lid 14 is relatively fixed so that bearing cap 8 dismounting when, axis
Hole must could also be passed through under specific angle by holding seat 5, it is ensured that the detent slot 16 on bearing block 5 can be with release key 10
The position grab 10a coincide, and place is in the same axial direction.Only sucker upper cover 13 of the key face 10b of release key 10 from cleaning appliance
It is pierced by, round brush lid 14 is good to 4 sealing effect of round brush.
In other embodiments of the invention, one end of round brush 4 is connected with drive block 9, and round brush 4 has and drive block
The identical mating groove 15 of 9 concave-convex profiles, drive block 9 apply the rotary force around round brush axis by mating groove 15 to round brush 4.
Beneficial effect by adopting the above technical scheme is：Drive block 9 play limitation round brush 4 around its own axially rotate from
By spending, it is ensured that can normally rotate carry out cleaning work after round brush 4 can be driven to install.
In other embodiments of the invention, as shown in Figure 10, Figure 14, drive block 9 is prism-frustum-shaped.Mating groove 15 is
For bell mouth shape, regular polygon shape is presented in the view projections frame that the edge of drive block 9 is parallel to 4 axis of round brush, and edge is parallel to
The cross-section diagram of 4 axis of round brush is at trapezoidal.
Beneficial effect by adopting the above technical scheme is：Prism-frustum-shaped drive block 9 is playing limitation round brush 4 around its own axis
To on the basis of the freedom degree of rotation, correcting is played the role of in the driving fast 9 of mating groove 15 and prism-frustum-shaped, when round brush 4 needs to fill
Hui Shi, even if being not aligned with the original installation site of round brush 4, mating groove 15 can guide round brush 4 to be installed to original fixed position.
A kind of cleaning appliance includes a kind of round brush rapid dismounting apparatus of any of the above.Sucker lower cover 12, sucker upper cover 13, rolling
Including round brush 4, bearing block 5 are all closed by brush lid 14, key face 10b is pierced by from round brush lid 14, for operator's finger push.
As shown in figure 14, driving motor 18 drives drive block 9 to rotate by belt 19, and drive block 9 then drives round brush 4 to rotate, and makes to roll
4 rotation of brush carries out cleaning work.
When 4 disassembly status of round brush, round brush 4, bristle 17, thimble 1, thimble pressing plate 2, compression spring 3, bearing block 4, bearing 6,
Roller brush shaft 7, bearing cap 8 are popped up from the space that sucker lower cover 12, sucker upper cover 13, round brush lid 14 fasten.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
