Background
Laser therapeutic apparatuses are widely used in the field of clinical treatment or cosmetology, and most of the existing laser nozzles are single nozzles for emitting laser, and the shape of the existing laser nozzles is similar to that of a pen. Most of the existing laser nozzles are of an integrated structure, the nozzle part of the laser nozzle is a quick-wear part, once damaged, the whole nozzle is about to be scrapped, and the size and specification of the nozzle outlet are different for different requirements, so that the nozzles of various types are produced, and the laser nozzle is not convenient to use and manage. On the other hand, the laser treatment inevitably damages the wound such as the skin, and the conventional nozzle is easily infected with the external bacteria in the process of cutting the body.
Disclosure of Invention
The invention aims to provide a laser nozzle for a laser beauty treatment machine, which can quickly replace a nozzle, has strong universality, reduces the rejection rate of the nozzle, can temporarily protect a body wound part during an operation and prevents bacterial invasion to a certain extent.
The technical scheme of the invention is as follows:
a laser nozzle for a laser beauty treatment machine is characterized in that a nozzle body is in a circular tube shape, a shaft collar is arranged on the outer wall of a connecting end, connected with a light guide arm, of the nozzle body, a section of cylindrical barrel is screwed and sleeved on the outer wall of the nozzle body through sealing threads, one end of the barrel is connected with the shaft collar, a gap is reserved between the inner wall of the barrel and the outer wall of the nozzle body to form a gas storage cavity for containing protective gas, a plurality of vent holes are formed in the pipe wall of the nozzle body, located in the gas storage cavity, of the nozzle body, the vent holes are all obliquely arranged towards the outlet end of the nozzle body, and;
the outlet end of the spray head body is coaxially screwed with a conical nozzle, the nozzle comprises a cylindrical part with threads and a conical part for ejecting laser and protecting airflow, the cylindrical part is screwed into the outlet end of the spray head body, a hexagonal mounting plate is arranged at the intersection of the cylindrical part and the conical part, and a sealing copper gasket is tightly clamped between the mounting plate and the end face of the outlet end of the spray head body.
Further, the axis of the vent hole and the axis of the nozzle form an included angle of 30 degrees.
Further, all the vent holes are in a circular array by taking the axis of the sprayer body as the center.
Furthermore, a convex mirror for condensing light is arranged in the inlet end of the nozzle body, all the vent holes are located between the convex mirror and the outlet end of the nozzle body, and the convex mirror converges laser light to the center of the small port of the conical part.
Furthermore, a plurality of smooth grooves are formed in the outer wall of the cylinder body along the axial direction of the cylinder body.
The invention has the beneficial effects that: after the laser enters the spray head body, the protective airflow continuously and uniformly gushes from the air vent and reaches the operation wound part together with the laser, the protective airflow is simultaneously generated at the laser wound part to temporarily protect the laser from bacteria invasion, a certain protective effect is achieved, and in order to not influence the emission of the laser, the air vent is uniformly inclined towards the outlet end of the spray head body, so that the interference is reduced. In addition, the nozzle and the spray head are not arranged in an integrated manner, can be replaced at any time, and are convenient to maintain or replace models, and the adaptability is extremely strong.
Drawings
FIG. 1 is a schematic view of the structure of the present invention.
Detailed Description
The following description of the embodiments of the present invention is provided for illustrative purposes, and other advantages and effects of the present invention will become apparent to those skilled in the art from the present disclosure.
The invention is further illustrated by the following examples in conjunction with the accompanying drawings:
as shown in fig. 1, a laser nozzle for a laser beauty treatment machine, a nozzle body 9 is in a shape of a circular tube, a collar 10 is arranged on the outer wall of a connecting end of the nozzle body 9 connected with a light guide arm, and a section of cylindrical barrel 11 is screwed on the outer wall of the nozzle body 9 through a sealing thread. One end of the cylinder 11 is connected with the shaft collar 10, and a gap is reserved between the inner wall of the cylinder 11 and the outer wall of the nozzle body 9 to form a gas storage cavity 12 for containing protective gas; the sealing can be realized by directly adopting a common sealing thread, because the protective gas flow is used for protecting the wound, the air pressure is relatively small, the protective gas flow can adopt inert gas such as helium, nitrogen and the like, and the protective gas can be changed into disinfectant when necessary. The pipe wall of the spray head body 9 positioned in the gas storage cavity 12 is provided with a plurality of vent holes 13, the vent holes 13 are all obliquely arranged towards the outlet end of the spray head body 9, and the cylinder wall of the cylinder 11 is provided with an air inlet joint 14 connected with an external protective air source.
The outlet end of the spray head body 9 is also coaxially screwed with a conical nozzle 15, the nozzle 15 comprises a cylindrical part with threads and a conical part for ejecting laser and protecting airflow, the cylindrical part is screwed into the outlet end of the spray head body 9, a hexagonal mounting plate 16 is arranged at the intersection of the cylindrical part and the conical part, the mounting plate 16 is mainly used for screwing the nozzle 15 by a wrench, the detachable connection is convenient to realize, and a sealing copper gasket 17 is tightly clamped between the mounting plate 16 and the end face of the outlet end of the spray head body 9.
Further, the axis of the vent hole 13 is at an angle of 30 degrees to the axis of the nozzle 15, so that the shielding gas flow is better concentrated to flow out of the nozzle 15, and the pumping pressure on the shielding gas flow is reduced.
Further, all air vents 13 are in circular array by taking the axis of the nozzle body 9 as the center, so that air flow can more uniformly flow in, and the influence of the air flow on laser is prevented.
Further, a convex mirror 18 for condensing light is arranged in the inlet end of the nozzle body 9, all the vent holes 13 are located between the convex mirror 18 and the outlet end of the nozzle body 9, the convex mirror 18 converges laser to the center of the small port of the conical part, so that the laser is prevented from being irradiated onto the inner wall of the conical part as far as possible to cause burning damage, and the service life is prevented from being reduced.
Further, the outer wall of the cylinder 11 is provided with a plurality of smooth grooves 1101 along the axial direction thereof for holding the cylinder 11 by hand for installation and screwing.
The foregoing embodiments are merely illustrative of the principles and utilities of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present invention. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical spirit of the present invention be covered by the claims of the present invention.
