Abstract
The utility model relates to a compressed gas nozzle for cleaning optical elements, which is composed of a cylinder member, wherein a tube chamber is arranged in the cylinder member, and one end of the tube chamber is connected with a container for compressed gas by a valve; the front end of the cylinder member is provided with at least three gas jetting holes, and all the gas jetting holes present cylinder tube shapes; an inner end of each gas jetting hole is communicated with the tube chamber, and an outer end of the gas jetting hole is provided with an opening at the front end surface of the cylinder member; the axial line of each gas jetting hole and the axial line of the cylinder member form an included angle from 45 DEG to 5 DEG, and extension lines of the axial lines of the gas jetting holes intersect at the same point on a forward extension line of the axial line of the cylinder member. When a gas flow passes through the gas jetting holes, the direction is changed, and after the gas flow rushes out the gas jetting holes, more than three gas flows converge at a certain point on the forward extension line of the axial line of the cylinder member, and the point can obtain a bigger pressure of gas flows; when the surfaces of the optical assemblies are placed close to the point, obdurate dust can be effectively removed.
Description
Technical field:
The utility model relates to medicine equipment, relates in particular to the optical module in the medical diagnosis instrument, the particularly cleaning device of optical module in the medical diagnosis instrument, and concrete is a kind of Compressed Gas nozzle that is used to clean optical element.
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 Compressed Gas to remove again and adhere to firm dust, but, Compressed 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 problem of the prior art to be solved in the utility model 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 Compressed Gas to remove again and adhere to firm dust, but, Compressed 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 utility model is that the technical scheme that solution above-mentioned technical problem of the prior art is adopted provides a kind of Compressed Gas nozzle that is used to clean optical element, the described this Compressed Gas nozzle that is used to clean optical element 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 fumaroles at least, any one described fumarole all is cylindrical tube, the inner of described fumarole all is communicated with described tube chamber, the outer end of described fumarole all is opened on the front end face of described cylinder component, the axial line of any one described fumarole 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 fumarole axial line all intersects on the same point on the cylinder component axial line extended line forwards.
Further, the diameter of described fumarole is identical.
Further, the number of described fumarole is four.
Operation principle of the present utility model is: Compressed Gas is through tube chamber, spray from the fumarole more than three, direction is changed during air-flow process fumarole, after going out fumarole, 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 utility model and prior art contrast, and its effect is actively with tangible.The utility model utilizes the fumarole 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 the Compressed Gas structure of nozzle schematic diagram that is used to clean optical element of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of Compressed Gas nozzle that is used to clean optical element of the utility model, 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 fumaroles 3 at least, any one described fumarole 3 all is cylindrical tube, the inner of described fumarole 3 all is communicated with described tube chamber 2, the outer end of described fumarole 3 all is opened on the front end face of described cylinder component 1, the axial line of any one described fumarole 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 fumarole 3 axial lines all intersects on the same point on the cylinder component 1 axial line extended line forwards.
Further, the diameter of described fumarole 3 is identical.
Further, the number of described fumarole 3 is four.
