Description
Technical field
The utility model relates to medicine equipment, is specifically related to the dental handpiece of a kind of movement and shower nozzle integral type.
Background technology
In dental handpiece maintenance time of collet-type movement, is very convenient, only need to open bonnet and just can directly take off movement and change, keep in repair. Chinese patent CN203988426U discloses a kind of dental handpiece of detachable shower nozzle, a dismountable shower nozzle is made separately in the water spray water route being arranged on dental handpiece heads, but this technical scheme is only that shower nozzle is made to independently parts, further do not optimize for parts such as movements.
Utility model content
In sum, in order to overcome the deficiencies in the prior art, technical problem to be solved in the utility model is to provide the dental handpiece of a kind of movement and shower nozzle integral type.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: the dental handpiece of a kind of movement and shower nozzle integral type, comprise head and the handle being connected with head, described head comprises handpiece case, be arranged on the movement with cylindrical shell in head, and movement is fixed on to the bonnet in head, be provided with in the bottom of described cylindrical shell and the one-body molded shower nozzle to downward-extension of this cylindrical shell, the bottom of described shower nozzle flushes with the bottom of described handpiece case, be provided with the spray holes that can spray atomization shape liquid in the bottom of described shower nozzle, and described in this spray holes pass-out outside handpiece case.
Further, on the circumferential side wall of described shower nozzle, annular is provided with a circle air drain, the sidewall of the described shower nozzle of described air drain below has tapering, this has between the shower nozzle sidewall of tapering and described handpiece case and forms tank, in described air drain and described tank, annular is evenly distributed with air admission hole and inlet opening respectively, described air drain is connected with gas circuit outlet and water route outlet in dental handpiece handle respectively with described tank, described air admission hole, described inlet opening and described spray holes are interconnected, high velocity air in described air admission hole is spraying from described spray holes after the water atomization in described inlet opening.
The beneficial effects of the utility model are: by collet-type movement and independently three hole nozzle structures be integrated together, make independently parts, in the time keeping in repair, remove and install more quick, after opening head bonnet, a direct step just can all have been taken off whole movement and shower nozzle, and maintain and replace is very convenient.
Further, described shower nozzle is up big and down small column structure.
The beneficial effect of above-mentioned further scheme is: the structure of this structure and dental handpiece heads shell matches, and installs simply, is connected firmly.
Further, on described shower nozzle, be also provided with for fixed seal ring seal groove.
Further, described handpiece case is the stainless structure of individual layer.
The beneficial effect of above-mentioned further scheme is: this structural volume is little, quality light, crash resistance can be good.
Brief description of the drawings
Fig. 1 is assembly structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of movement;
Fig. 3 is the cutaway view of movement.
In accompanying drawing, the list of parts of each label representative is as follows:
1, head, 2, handle, 3, handpiece case, 4, movement, 41, cylindrical shell, 42, shower nozzle, 43, air admission hole, 44, water inlet, 45, spray holes, 46, air drain, 47, tank, 48, seal groove, 5, head bonnet.
Detailed description of the invention
Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.
As Figure 1-3, the dental handpiece of a kind of movement and shower nozzle integral type, comprise head 1 and the handle 2 being connected with head 1, described head 1 comprises handpiece case 3, be arranged on and be fixed on the head bonnet 5 in head 1 with the movement 4 of cylindrical shell 41 and by movement 4 in head 1. Preferred: described handpiece case 3 is the stainless structure of individual layer, handpiece case 3 volumes of this structure are little, quality light, crash resistance can be good. Be provided with in the bottom of described cylindrical shell 41 and the one-body molded shower nozzle 42 to downward-extension of this cylindrical shell 41, the bottom of described shower nozzle 42 flushes with the bottom of described handpiece case 3. Be provided with the spray holes 45 that can spray fog-like liquid in the bottom of described shower nozzle, and described in these spray holes 45 pass-outs outside handpiece case 3.
On the circumferential side wall of described shower nozzle 42, annular is provided with a circle air drain 46, the sidewall of the described shower nozzle 42 of described air drain 46 belows has tapering, this has between shower nozzle 42 sidewalls of tapering and described handpiece case 3 and forms tank 47, be evenly distributed with air admission hole 43 and inlet opening 44 at described air drain 46 and the interior annular respectively of described tank 47, described air drain 46 is connected with gas circuit outlet and water route outlet in dental handpiece handle respectively with described tank 47, described air admission hole 43, described inlet opening 44 and described spray holes 45 are interconnected, high velocity air in described air admission hole 43 is spraying from described spray holes 45 after the water atomization in described inlet opening 44. the movement of dental handpiece has following two classes: a class is with cylindrical shell, an other class be not with cylindrical shell, with the collet-type of crying of cylindrical shell. the utility model is for the dental handpiece with cylindrical shell movement. by collet-type movement and independently three hole nozzle structures 42 be integrated together, make independently parts, just convenient in the time keeping in repair like this, after opening head bonnet 5, a direct step just can all have been taken off whole movement 4 and shower nozzle 42, and maintain and replace is very convenient. because shower nozzle 42 and collet chuck movement 4 are integrative-structures, more easily take off from dental handpiece than independent before shower nozzle, then carry out the cleaning of apopore.
On described shower nozzle 42, be also provided with for fixed seal ring seal groove 48, at the interior sealing ring that arranges of seal groove 48, increase the tightness between shower nozzle 42 and handpiece case 3.
