[0016] With reference to FIG. 4, the coupling means 22 has a conic
part 222 and a guiding groove 223. The conic part 222 pierces a
clamping board 23 in the sheath pipe 20 and guides the clamping
board 23 into the guiding groove 223 such that the coupling means
22 is fixed in the clamping board 23.
[0017] The coupling means 22 has a ring 224, the outer end of the
ring 224 abuts the inner wall of the sheath pipe 20, as shown in
FIG. 4. The ring 224 prevents the coupling means 22 from being
inclined in the sheath pipe 20. Another end of the coupling means
22 is invaginated with a first tightening ring 225 and the duct 30.
The first tightening ring 225 enhances the coupling force between
the coupling means 22 and the duct 30 and prevents detach of the
coupling means 22 from the duct 30.
[0018] The duct 30 is made of flexible rubber and is of hollow
shape to convey vapor therein. One end of the duct 30 is connected
to the coupling means 22 as shown in FIG. 4 and another end of the
duct 30 is invaginated with a second tightening ring 226 and a
nozzle 71. The second tightening ring 226 enhances the coupling
force between the nozzle 71 and the duct 30 and prevents detach of
the nozzle 71 from the duct 30.
[0019] The rotation means 40 encloses outer wall of the duct 30 as
shown in FIG. 4 and the top end of the rotation means 40 is
pivotally connected to the grooves 24 on both sides of the sheath
pipe 20 whereby the sheath pipe 20 and the connection tube 80 can
swing forward and backward to clean dead space as shown in FIG.

enhance the coupling force between the connection units 50 and the
upper cover 60 and prevent detach of the connection units 50 from
the upper cover 60.
[0025] The connection unit 50 is integrally formed by mold
injection and has a slit 51 on topside thereof. The slit 51 is used
to clamp de-dirt paper or wipe for cleaning dirt. The connection
unit 50 has a plurality of hooking grooves 52 on bottom thereof,
which are hooked to the clamping grooves 622 and prevent detach of
the connection units 50 from the upper cover 60.
[0026] The bottom plate 70 is integrally formed by mold injection
and has a rounded hole 72 and a plurality of posts 73. The posts 73
are corresponding to the threaded holes 621 in the recesses 62. The
posts 73 have threads 731 therein and the threads 731 are
corresponding to the screws 623.
[0027] The bottom plate 70 has a concave room 74 and a plurality of
orifices 741 as shown in FIG. 4. The concave room 74 can be used to

side thereof to increase the spraying area of vapor and send the
high-temperature vapor to the nozzle 71 through the coupling means
22 and the conveying tube 81. The vapor is emitted from the nozzle
71 and then uniformly through the plurality of orifices 741 on the
bottom plate 70.
[0029] The nozzle 71 can be made by metal or plastic and is locked
with the rounded hole 72. The nozzle 71 is retained by the second
tightening ring 226 and coupled to the duct 30, thus forming a
complete retaining structure for brush of vapor cleaner as shown in
FIG. 3.
[0030] As shown in FIG. 5, in the present invention, the
high-temperature vapor is sent to the nozzle 71 through the
coupling means 22 and the conveying tube 81. The vapor is emitted
from the nozzle 71 and then uniformly through the plurality of
orifices 741 on the bottom plate 70. The high-temperature vapor has
the effect of cleaning pests such as flea and louse.
