And middle section and foremost section of the valve stem 212 are interlinked with an O-ring seals 2122 and 2123, and a spring 2124 is interlinked with the middle section of the valve stem 212 from the big hole 2115 of the valve hole 211, and the pull knob is combined with the valve stem 212 from the small hole 2114 of the valve hole 211. Lastly, the bulged pipe 215 should be connected at the end of the big hole 2116 of the valve hole 211.
The teeth cleaner can be laid on a frame 30 fixed on the wall. The frame 30 is an inverse L-shaped sheet, whose wall side 31 is designed with a perforation 311, so that the fixing unit 312 can be screwed into the wall for fixing. And at the central bottom, a round base 313 is available for the placement of the handle 10; in addition, some equidistant slots 321 are set on the vertical sheet 32 and a recess 322 is designed at the semicircular base 313 the center is corresponding to, for the placement of the spurt gun and the teeth cleaner.
As shown in FIG. 12, the frame 60 fixed on the wall for the replacement of the teeth cleaner can be a semicircular one with upper and lower layers. Its wall side has perforation 611, so that the fixing unit can be screwed into the wall for fixing; and its lower layer has many equidistant slots 621 for the insertion of the spurt gun 11, while the center has a recess 622 for the replacement of the teeth cleaner; and at the center of the upper layer, a recess 623 is available for the teeth cleaner, besides some equidistant recesses 624 designed at the outer edge.
The both ends of the silica gel tube 19 are connected and fixed by an empaistic ring 40 and quick coupler 50. So it can be assembled or disassembled easily.
Referring to FIG. 7, FIG. 8, FIG. 10-A, FIG. 10-B and FIG. 10-C, the quick coupler 50 interlinked in the position groove 2153 of the internal locking ring 2152 of the water outlet 2151 of the bulged pipe 215 of the switching connector 21 comprises: an elastic locking ring 51 whose internal peripheral ring has many locking sheets 511, and a locking base 53 whose center is designed as a pipeline 521, and the end of the pipeline has a ring-shaped pushing edge 522.
Referring to FIG. 1-FIG. 6, as far as the assembly of the present invention concerned, the handle 10 is put into the internal pipe 17 firstly, and its both ends are connected to the T-shaped pipe 16 and spurt gun 11, and rotiform joint respectively, so that the empaistic ring 40 can lock the silica gel pipe 19. And the another end of the silica gel pipe 19 is interlinked on the switching connector 21 of the water pipe 20 with a quick coupler 50, further to form a whole one. Therefore, the smooth and convenient operation can be realized.
In addition, while using the teeth cleaner, as shown in FIG. 3, the whole set of teeth cleaners and single spurt gun 11 can be placed on the frame 30, which is fixed on the wall with a fixing unit 312, so that the user can select his/her own spurt gun 11 and assemble it on the teeth cleaner to rinse the teeth (as shown in FIG. 4).
The spurt gun 11 of the present invention can be designed in various colors, so that the member of a family can distinguish their own spurt gun 11, meeting the personal sanitation requirement; the spurt gun 11 can be placed or taken conveniently, because it is cone-shaped. And the dentiform ring-shaped edge 13 at its end should be placed in the slots 321 of the frame 30 for stable fixing; The whole set of teeth cleaner the present invention provides can be taken or placed easily while being placed in the recess 322 and semicircular base 313 of the frame. The spurt gun 11 can be separated from the handle 10 and replaced easily by only averting the dentiform ring-shaped edge 13, and then by interlinking the spurt gun with the threading ring.
Because each spurt gun 11 is detachable from the handle 10, we can buy the teeth cleaner by selecting the single handle arranged with the quantity of required spurt guns 11. After using for some time, the spurt gun 11 can be discarded and replaced.
Therefore, the improved teeth cleaner can be installed in hotels and restaurants etc. And owners can provide a handle and spurt guns with required quantity in each room without much additional cost, so as to replace the used ones after guests' leaving and obtain good service quality and sanitation effect.
Moreover, when user takes the teeth cleaner to rinse his/her teeth, user can pull outwards the pull knob 2121 of the switching connector 21 connected to the water pipe 20 to make valve stem overcome the elasticity of the spring 2124, the foremost end 2125 and O-ring seal 2123 at foremost section will hold the junction of the big hole 2116 and medium hole 2115 of the valve hole 211 to make the water flow by the interior of threading ring 213 of the switching joint 21, by top flow channel 2112 of the valve hole 2111 of the valve pipe 211, and by big and medium hole 2116, 2115 of the valve hole 2111, and by the internal joint of the bulged pipe 215 and valve hole 2111 and to the interior of the bulged pipe 215, lastly, by the spurt gun 11 through the silica gel tube 19, and would be sprayed by the nozzle 12 towards the cleaned teeth; contrarily, on the occasion of nonuse, just to shut off the water or push the pull knob 2121 of switching joint inwards to make the spring 2124 interlinked at the middle section of the valve stem 212 push the valve stem 212 onwards actively with its elasticity, and the foremost edge 2125 of the valve stem 212 and 0-ring seal 2123 at the foremost section can hold the internal junction of the bulged pipe 215 and valve hole 2111 tightly. Lastly replace the teeth cleaner on the frame.
And, the switching joint on the silica gel tube 19 and the water pipe 20 is fixed with a quick coupler 50 to make the silica gel tube 19 directly can be interlinked from the pipeline 521 at the center of the locking base 53 (as shown in FIG. 10-A), when the water outlet 2151 of the bulged pipe 215 20 is combined with the silica gel tube 19, by the locking sheet 511 designed at the internal peripheral ring within the elastic locking ring 51, lastly, by the locking ring 2152. Based on the action of the locking sheet 511, the silica tube 19 can be integrated with the bulged tube 215 by means of locking (as shown in FIG. 10-B); While separating the silica gel tube 19 from the bulged pipe 215, the locking base 53 can pushed towards the bulged pipe 215 to make the ring-shaped pushing edge 522 at the end of pipeline 521 push the locking sheet 511 designed at the internal peripheral ring within the elastic locking ring 51 outwards, so as to make the silica gel tube 19 no longer be locked by the locking sheets 511; lastly to take the silica gel tube 19 out. Therefore the teeth cleaner not only can be assembled or disassembled easily, but also its service life can be extended (as shown in FIG. 5, FIG. 6, FIG. 10-A, FIG. 10-B and FIG. 10-C).
Besides, as shown in FIG. 11, the middle section of the valve stem 212 can not be interlinked with any other spring 2124, so that we can further select and control output or switch of the bulged pipe 215 or water filter 214 manually when the water accesses to the interior of the switching joint 21.
And, the water pipe connected with the switching joint 21 can be equipped with a one way faucet with single cool water outlet or combination faucet with cool and warm water outlets to make the water temperature from the teeth cleaner can be adjusted to the required one (such as teeth's sensibility to cool or living in frigid zone). Thus it can be used widely.
