Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
As shown in Figure 1, a kind of novel dental handset machine head, including shell 1 and the rotating mechanism being set in shell 12.
Wherein rotating mechanism 2 is formed by vehicle needle, wind wheel, for carrying the miniature bearing up and down of wind wheel.Shell 1 includes accommodating rotating mechanism
It 2 accommodating chamber 11 and is connect with accommodating chamber 11 and outwardly extending connecting cavity 12, accommodating chamber 11 and connecting cavity 12 pass through injection molding
It is integrally formed connection.Be provided in connecting cavity 12 along 12 length direction of connecting cavity distribution link block 13, link block 13 with connect
Chamber 12 is integrally formed.Inlet channel 131 for blowing into accommodating chamber 11 is provided on link block 13 and for being discharged
The exhaust passage 132 of gas in accommodating chamber 11.It is additionally provided on link block 13 for the water channel 133 of water spray and for making water channel
The atomization air flue 134 that 133 water is atomized and is sprayed.Water channel 133 is set to the top of atomization air flue 134, and water channel 133
Length direction is parallel with the atomization length direction of air flue 134.It is additionally provided with hole for water spraying 121 in connecting cavity 12 and is set to water spray
Water spray mold insert 3 in hole 121 is respectively arranged in mold insert 3 of spraying water and water channel 133 and is atomized the apopore that is connected of air flue 134
31 and venthole 32.It can prevent from generating contracting hole in injection molding process by the setting of hole for water spraying 121 and water spray mold insert 3, because
It is typically all to be molded by, and the aperture in the hole is generally 0.3-0.5mm for hole for water spraying in existing plastic machine head, this youngest is small
Aperture be molded by and come relatively difficult, often will appear that the hole shape for being molded by and is irregular and hole wall generates contracting hole etc., shadow
Outlet effect is rung, and then influences the grinding effect to tooth, such thing occurs in order to prevent in existing plastic machine head, has
Take more complicated Shooting Technique to be controlled, cost is greatly improved in this, some by the way of secondary polishing,
But the mode of secondary polishing is very difficult to control for so small aperture, it is desirable that relatively high, this causes the increase of cost again
The case where, simultaneously because water channel 133 is set to the top of atomization air flue 134, water spray effect can be improved, prevent not to be discharged
Or the situation generation that water outlet is excessive.
As shown in Fig. 2, apopore 31 and venthole 32 are not communicated with, and the central axis on the length direction of apopore 31 prolongs
Long line intersects with the central axis extended line on the length direction of venthole 32.When due to apopore 31 and identical venthole 32,
The gentle cognition of water is mixed and then is spraying, be easy to appear air pressure it is excessively high or too low when, the case where not generating atomized water, because
This apopore 31 and venthole 32 are not communicated with, and be can produce lasting atomized water, are improved water spray effect.The length of apopore 31
Perpendicular to the length direction of link block 13, the angle between 31 length direction of length direction and apopore of venthole 32 is in direction
25°-30°.After the angular range is conducive to gas to water effect, makes what atomized water more concentrated to spray towards vehicle needle direction, subtract
The case where few atomized water excessively disperses after spraying.Apopore 31 along water spray mold insert 3 length direction through setting, venthole 32 by
Setting is run through to the side wall of water spray mold insert 3 in water spray surface of the mold insert 3 far from 13 one end of link block.The structure can be conducive to water by
The generation in the effect of gravity quickly leaves, prevents water blockoff the case where.Water channel 133 includes horizontal part 1331 and vertical portion 1332, is erected
The length direction in straight portion 1332 is vertical with the length direction of horizontal part 1331, and the other end and apopore 31 of vertical portion 1332 connect
It is logical.Central axis on 1332 length direction of vertical portion is overlapped with the central axis on the length direction of apopore 31, and vertical
The diameter in portion 1332 is greater than the diameter of apopore 31.The structure is since there are size changes for the diameter of vertical portion 1332 and apopore 31
Change, can raise speed to water body, acceleration is atomized out water speed.It is atomized the surface of 134 one end of air flue protrusion link block 13, it is another
The outlet passageway 1341 being connected to venthole 32, the central axis of the length direction of outlet passageway 1341 are provided on the side wall at end
It is overlapped with the central axis on the length direction of venthole 32.The structure can guarantee the leakproofness for being atomized air flue 134, guarantee defeated
Stable gas pressure out, and then guarantee the effect stability of entire atomized water and continue.
Above are merely preferred embodiments of the utility model, it is noted that for the ordinary skill people of the art
Member for, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
