Abstract
The invention is an air vent guide pipe structure for eliminating dusts on the surface of an optical component, composed of a cylindrical component, where the cylindrical component is provided with a pipe cavity inside, one end of the pipe cavity is connected through a valve to a compressed air container, the front end of the cylindrical component is at least provided with three air vents, each of which is a cylindrical pipe in shape, the inner end of each air vent is connected with the pipe cavity and the outer end is made with an opening on the front end surface of the cylindrical component, the axle of each air vent forms an inclined angle of 45-5 deg. with that of the cylindrical component, and the extension lines of all the air vents intersect at the same point in the forward extension line of the axle of the cylindrical component. As an air flow passes through the air vents, its direction will be changed, and vented from the air vents, above three air flows gather at some point on the forward extension line of the axle of the cylindrical component so that this point obtains larger air flow pressure, therefore it can effectively eliminate hard dusts on the surface of an optical component arranged near this point.
Description
Technical field:
The present invention relates to medicine equipment, relate in particular to the optical module in the medical diagnosis instrument, the particularly cleaning device of optical module in the medical diagnosis instrument, concrete is a kind of air jet duct structure of removing optical element surface dust.
Background technology:
In the prior art, optical module in the medical diagnosis apparatus such as lens, reflection device etc. all contact with air, so can be infected with dust, simultaneously, the internal components of medical diagnosis apparatus can produce more static, make the static dust of having more become easily infected by on optical module, so that influence the image quality of medical diagnosis apparatus.Usually, the dust of removing optical module is to blow up a balloon by one to carry out, but the stream pressure that blows up a balloon a little less than, be not enough to remove the firm dust of adhesion, therefore, people utilize canned pressure gas to remove again and adhere to firm dust, but, pressure gas is gone out nozzle and is promptly dispersed later on and advance, and forms a coniform path, and the stream pressure that acts on the optical module surface disperses to weaken greatly.
Summary of the invention:
Technical matters of the prior art to be solved by this invention is: because in the prior art, optical module in the medical diagnosis apparatus such as lens, reflection device etc. all contact with air, so can be infected with dust, simultaneously, the internal components of medical diagnosis apparatus can produce more static, make the static dust of having more become easily infected by on optical module, so that influence the image quality of medical diagnosis apparatus.Usually, the dust of removing optical module is to blow up a balloon by one to carry out, but the stream pressure that blows up a balloon a little less than, be not enough to remove the firm dust of adhesion, therefore, people utilize canned pressure gas to remove again and adhere to firm dust, but, pressure gas is gone out nozzle and is promptly dispersed later on and advance, and forms a coniform path, and the stream pressure that acts on the optical module surface disperses to weaken greatly.
The technical scheme that the present invention is adopted for solution above-mentioned technical matters of the prior art provides a kind of air jet duct structure of removing optical element surface dust, the air jet duct structure of described this removal optical element surface dust is made of a cylinder component, be provided with tube chamber in the described cylinder component, one end of described tube chamber is connected with pressurization-gas cascade by valve, wherein, the front end of described cylinder component is provided with three gas orifices at least, any one described gas orifice all is cylindrical tube, the inner of described gas orifice all is communicated with described tube chamber, the outer end of described gas orifice all is opened on the front end face of described cylinder component, the axial line of any one described gas orifice all and the axial line of described cylinder component form between 45 and spend to the angle between 5 degree, the extended line of described gas orifice axial line all intersects on the same point on the cylinder component axial line extended line forwards.
Further, the diameter of described gas orifice is identical.
Further, the number of described gas orifice is four.
Principle of work of the present invention is: pressure gas is through tube chamber, spray from the gas orifice more than three, direction is changed during air-flow process gas orifice, after going out gas orifice, air-flow more than three strands converge on the cylinder component axial line extended line forwards certain a bit, this place promptly obtains bigger stream pressure, and the surface of optical module is placed near this point, promptly can effectively remove obstinate dust.
The present invention and prior art contrast, and its effect is actively with tangible.The present invention utilizes the gas orifice more than three to converge air-flow, so can obtain bigger stream pressure, can effectively remove the obstinate dust on the optical module in the medical diagnosis apparatus.
Description of drawings:
Fig. 1 is a kind of synoptic diagram of removing the air jet duct structure of optical element surface dust of the present invention.
Embodiment:
As shown in Figure 1, a kind of air jet duct structure of removing optical element surface dust of the present invention, constitute by a cylinder component 1, be provided with tube chamber 2 in the described cylinder component 1, one end of described tube chamber 2 is connected with pressurization-gas cascade by valve, wherein, the front end of described cylinder component 1 is provided with three gas orifices 3 at least, any one described gas orifice 3 all is cylindrical tube, the inner of described gas orifice 3 all is communicated with described tube chamber 2, the outer end of described gas orifice 3 all is opened on the front end face of described cylinder component 1, the axial line of any one described gas orifice 3 all and the axial line of described cylinder component 1 form between 45 and spend to the angle between 5 degree, the extended line of described gas orifice 3 axial lines all intersects on the same point on the cylinder component 1 axial line extended line forwards.
Further, the diameter of described gas orifice 3 is identical.
Further, the number of described gas orifice 3 is four.
