Detailed Description
In order to make the technical scheme of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 10, wherein fig. 1 and 2 show schematic structural views of the photoelectric sensor and the light reflection groove or the light absorption groove in three groups; while fig. 9 and 10 show schematic structural diagrams of the photosensor and the light reflection groove or the light absorption groove in four groups.
The invention relates to a strong pulse light treatment hand tool capable of rapidly identifying a multiband optical filter, which comprises:
a hand tool body;
a light generating component integrated with the hand tool body;
the optical identification component is integrated in the hand tool body;
the optical transmission component is integrated in the hand tool body;
the light identification component is arranged on the light generation component and the light transmission component and is used for identifying the light signal input by the light generation component and emitting strong pulse light outwards through the light transmission component;
the optical recognition component is provided with a PCB 4 and an optical filter component 5 matched with the PCB 4;
the PCB 4 is formed with a plurality of groups of photoelectric sensors 401;
the filter component 5 is provided with a light reflection groove and a light absorption groove 50101 matched with the photoelectric sensor 401;
the photosensor 401 receives different feedback signals in cooperation with the light reflecting slot and the light absorbing slot 50101 to control the light transmitting assembly to emit different strong pulsed light.
Specifically, the embodiment discloses a strong pulse light treatment hand tool capable of rapidly identifying optical filters with various wave bands, which is assembled with an external device for use on the basis of a hand tool body; the light generating component, the light identifying component and the light transmitting component are integrated in the hand tool body. The light generating component generates emitted light, and then the light with the corresponding wave band is identified through the light identifying component and emitted through the light transmitting component, so that targeted treatment and use are completed. Wherein, be different from the hand utensil in the prior art: the light identification component of the treatment hand tool of the embodiment realizes the identification of light with various wave bands through the cooperation of the photoelectric sensor 401 on the PCB 4 and the light reflection groove or the light absorption groove 50101 in the optical filter component 5 so as to output the emitted light with various wave bands outwards; of course, it can be understood that the corresponding numbers of the photoelectric sensor 401 and the light reflection grooves and the light absorption grooves 50101 in the present embodiment determine the number of the bands that can be identified, and when the photoelectric sensor 401 and the light reflection grooves or the light absorption grooves 50101 are all four groups, they can identify light of sixteen bands, but since only light of eight bands needs to be identified in the present invention, it is considered that once the partial identification line of the filter assembly is broken, there is a possibility that the host erroneously identifies the low band spectral output as the high band. Under the same energy density, the initial injection voltages corresponding to the spectrums of different wave bands are different (the voltage injected in the high wave band is higher than the voltage in the low wave band), so that once a host mistakenly recognizes the low wave band as a filter in the high wave band, the injection voltage is increased, the light transmittance through the same filter is kept unchanged, and the final output energy density is increased due to the increase of the injection voltage, so that the human body is injured. To avoid this, 8 combinations are selected from the 16 arrangements of the light reflection grooves or the light absorption grooves, and the selection of the 8 different filter components ensures that even if part of the identification lines of the filters are disconnected, the host can only identify the high-band filter component as the low-band filter component (or the present-band filter component) without the possibility of identifying the low-band filter component as the high-band filter component, so that the density of the output energy of the final output end through the hand tool output end is less than or equal to the density of the actually required output energy, and the use safety is ensured. The eight filter assemblies used in the present invention have light reflection and absorption grooves arranged in the order of 0111, 1110, 0011, 0110, 1100, 0001, 0010, 0100 from the high band to the low band (420 nm-1200 nm), where 1 represents a light absorption groove and 0 represents a light reflection groove.

Finally, the light transmission assembly comprises a first sapphire light guide crystal 6 embedded at the lower end of the hand tool body, a heat dissipation shell 7 is arranged around the first sapphire light guide crystal 6, and the lower end of the first sapphire light guide crystal 6 is exposed out of the heat dissipation shell 7 to form a treatment end 601;

graph two: the photoelectric sensor is in the form of four groups of arrangement and combination of time light reflection grooves or light absorption grooves 50101.
The photoelectric sensor 401 is always powered on, so that the emitting end of the photoelectric sensor always emits an optical signal. The feedback signals received by the receiving ends of the photoelectric sensors 401 of the light reflection grooves or light absorption grooves 50101 with different arrangement sequences are also different, namely the sixteen cases are respectively corresponding to the light reflection grooves or light absorption grooves 50101 with different arrangement combinations. Through pre-storing program codes of different wave bands corresponding to sixteen signals in a program, when the non-passing wave band filter 502 is inserted, the main controller can quickly and accurately determine the type of the inserted filter assembly 5 by reading the received signal values and calling the stored program, and the parameter information of the inserted filter assembly 5 is displayed in real time through a display device. 8 filters are selected from sixteen filters, and the eight filters are sequenced from high to low bands, so that even if part of identification lines in the filters are disconnected, a host can only identify the high band filter assembly as the low band filter assembly (or the band filter assembly) without the possibility of identifying the low band filter assembly as the high band filter assembly, and the density of the output energy of the final output end through the hand tool output end is smaller than or equal to the density of the actually required output energy, and the use safety is ensured.
