Abstract
The invention discloses a triple-purpose spray gun sprayer structure for the dentistry. The structure comprises an inner tube and an outer tube, wherein the inner tube and the outer tube are arranged coaxially in a sleeved mode, a tube cavity of the inner tube is a water flow channel, a cavity between the outer tube and the inner tube serves as an air flow channel, and the water outlet end portion of the water flow channel is provided with a device capable of reducing water outlet pressure. The structure has the obvious advantages that the water outlet pressure can be effectively reduced due to the fact that the water outlet end portion of the water flow channel is provided with the device capable of reducing the water outlet pressure, pressure on affected parts of a patient is reduced, and therefore pains and mental stress of the patient are reduced; the device capable of reducing the water outlet pressure can disperse water outlet columns, and therefore the effect of cleaning the oral cavity and teeth is well achieved.
Description
Technical field
The present invention relates to a kind of dentistry and dental care field, particularly a kind of dental three ways syringe nozzle structure.
Background technology
Three ways syringe is the burnisher of a kind of dental oral treatment use, for to patient oral cavity injection water and/or air.Usually, when completing a treatment step, need to clean oral cavity comprehensively, now use the function of water spray, and in therapeutic process, when oral cavity needs local desiccation (as root canal open the dental pulp step after), use air injection function, as in therapeutic process, when oral cavity needs moistening or local cleaning, just use the function of atomized water spray (water and air).Wherein, can pass through to regulate the expulsion pressure of three ways syringe during atomized water spray, thereby control the atomized drop size, in order to carry out the cleaning of more different modes.
Existing three ways syringe is when water spray, after the rinse water pressurized, directly by sparge pipe, spray, because pressure is difficult for controlling, easily cause hydraulic pressure excessive, and the water of ejection is straight column type, easily causes patient's tooth affected part is formed to larger hydraulic pressure, allow patient's pain aggravate, and the water column injection point is comparatively concentrated, can better not reach cleaning performance on the one hand, increase on the other hand patient's mental pressure.
Summary of the invention
For solving the deficiencies in the prior art, the object of the present invention is to provide a kind of three ways syringe nozzle structure, this structure can make the water scattering of ejection, the wider oral cavity cleaning that carries out of one side, the hydraulic pressure formed on the other hand is less, alleviates the patient suffering.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
A kind of dental three ways syringe nozzle structure, comprise inner and outer tubes, and the inner and outer tubes concentric is sheathed, the tube chamber of inner tube is as water stream channel, cavity between outer tube and inner tube, as gas channel, is characterized in that, described water stream channel water outlet end is provided with the device that can reduce water outlet hydraulic pressure.
A kind of dental three ways syringe nozzle structure, is characterized in that, the described device that reduces water outlet hydraulic pressure is the partition with several apopores, and the water of ejection is dispersed into a plurality of little water columns by apopore.
A kind of dental three ways syringe nozzle structure, is characterized in that, the number of described apopore is 8-30.
A kind of dental three ways syringe nozzle structure, is characterized in that, the described device that reduces water outlet hydraulic pressure, for going out hydroturbine, goes out hydroturbine and is fixed in water stream channel water outlet end, and the water of ejection is dispersed into a plurality of water columns by driving the turbine rotation.
A kind of dental three ways syringe nozzle structure, is characterized in that, describedly goes out hydroturbine and water stream channel water outlet end is that card slot type is fixed.
Usefulness of the present invention is: 1. be provided with the device that can reduce water outlet hydraulic pressure in water stream channel water outlet end, can effectively reduce discharge pressure, reduce its pressure to the disease affected part, thereby reduce patient's misery and mental pressure; 2. this device that reduces water outlet hydraulic pressure can make the water outlet water column disperse, thereby can better reach, rinses the mouth and the effect of tooth.
The accompanying drawing explanation
Fig. 1 is the nozzle structure of the three ways syringe with apopore partition schematic diagram of the present invention;
Fig. 2 is the three ways syringe nozzle structure schematic diagram with going out hydroturbine of the present invention.
The implication of Reference numeral in figure: 1. outer tube, 2. gas channel, 3. apopore, 4. water stream channel, 5. inner tube, 6. go out hydroturbine.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
In conjunction with Fig. 1, a kind of dental three ways syringe nozzle structure, comprise inner tube 5 and outer tube 1, inner tube 5 and outer tube 1 concentric are sheathed, the tube chamber of inner tube 5 is as water stream channel 4, cavity between outer tube 1 and inner tube 5 is as gas channel 2, be provided with the partition with 26 apopores in water stream channel 4 water outlet ends, the water of ejection is dispersed into a plurality of little water columns by apopore, when reducing water column pressure, make the ejection water column be dispersed into a plurality of little water columns by each aperture, can be wider rinse the mouth and tooth.
A kind of dental three ways syringe nozzle structure, except said structure, difference is, described apopore number is 8, and is uniformly distributed on partition.
A kind of dental three ways syringe nozzle structure, except said structure, difference is, described apopore number is 30, and is uniformly distributed on partition.
In conjunction with Fig. 2, a kind of dental three ways syringe nozzle structure, comprise inner tube 5 and outer tube 1, inner tube 5 and outer tube 1 concentric are sheathed, the tube chamber of inner tube 5 is as water stream channel 4, cavity between outer tube 1 and inner tube 5 is as gas channel 2, be fixed with out hydroturbine in water stream channel 4 water outlet ends, going out hydroturbine and water stream channel water outlet end is that card slot type is fixed, the water of ejection is dispersed into a plurality of water columns by driving the turbine rotation, when reducing water column pressure, make the ejection water column be dispersed into a plurality of little water columns by each aperture, can be wider rinse the mouth and tooth.
Above demonstration and described ultimate principle of the present invention, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
