DETAILED DESCRIPTION OF THE INVENTION

[0013] With reference now to FIGS. 2, 3, 4 and 5, the present invention is intended to provide a retaining device for brush of vapor cleaner. The retaining device is arranged at front end of the vapor cleaner and can be used to clamp de-dirt paper or wipe for cleaning. The retaining device comprises a sheath pipe 20, a coupling means 22, a duct 30, a rotation means 40, a plurality of connection units 50, an upper cover 60 and a bottom plate 70.

[0014] The sheath pipe 20 is integrally formed by ejection molding and is of hollow shape. The sheath pipe 20 has two openings 21 and 211 on both ends thereof as shown in FIGS. 2. The opening 211 at top of the sheath pipe 20 is connected to a connection tube 80 (as shown in FIG. 4) of a vapor cleaner (not shown). The connection tube 80 has a conveying tube 81 for conveying the vapor generated by the vapor cleaner. The opening 21 at the bottom of the sheath pipe 20 has grooves 24 on both sides thereof and pivotally connected to the rotation means 40, as shown in FIG. 3.

[0015] The sheath pipe 20 contains a coupling means 22, which is of hollow shape to conduct the vapor produced by the vapor cleaner. One end of the coupling means 22 is connected to the duct 81 as shown in FIG. 4. One end of the coupling means 22 has an annulus loop 221 to enhance the coupling force between the coupling means 22 and the conveying tube 81 and prevent detach of the coupling means 22 from the conveying tube 81.

[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. 5.

[0020] The rotation means 40 is composed of a first semi-body 41 and a second semi-body 42, which enclose the outer wall of the duct 30 after assembling thereof. The first semi-body 41 has a first pivot shaft 411 and the second semi-body 42 has a second pivot shaft 421. The first pivot shaft 411 and the second pivot shaft 421 are pivotally connected to the grooves 24 of the sheath pipe 20.

[0021] The first semi-body 41 of the rotation means 40 has a dent 413 and the second semi-body 42 has a dent 423. The two dents 413 and 423 together cover the outer wall of the duct 30 at center of the two semi-bodies 41 and 42.

[0022] The first semi-body 41 of the rotation means 40 has two third pivot shafts 412 on both sides thereof, the second semi-body 42 of the rotation means 40 has two fourth pivot shafts 422 on both sides thereof. The third pivot shafts 412 and the fourth pivot shafts 422 are pivotally arranged in lug 61 of the upper cover 60, whereby the upper cover 60 connected to the rotation means 40 can swing laterally.

[0023] The upper cover 60 is integrally formed by mold injection and has two lugs 61 extended therefrom. The two lugs 61 are oppositely arranged on the upper cover 60 and have coupling grooves 611 therein. The coupling grooves 611 are pivotally connected to the third pivot shafts 412 and the fourth pivot shafts 422.

[0024] The upper cover 60 has a plurality of recesses 62 in which the connection units 50 are fixed. The recesses 62 contain threaded hole 621 and a plurality of clamping grooves 622. The threaded hole 621 can be used with screw 623 to fix the bottom plate 70. The clamping grooves 622 are locked with a plurality of hooking grooves 52 on bottom of the connection units 50. The hooking grooves 52 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 accommodate the nozzle 71 and prevent the jam of the orifices 741 of the nozzle by paper or wipe.

[0028] The bottom plate 70 has a plurality of orifices 741 on one 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.
