DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] like Figure 1-Figure 3 As shown, the three-in-one multifunctional laser module comprises an outer shell 1 and a red laser module 2, an infrared laser module 3, and a zoom laser irradiation module 4 installed inside the outer shell 1; The red laser module 2 and the infrared laser module 3 include a red laser diode 21 and an infrared laser diode 31, respectively. The red laser module 2 and the infrared laser module 3 also include a module housing 22 arranged outside the red laser diode 21 and the infrared laser diode 31, a mirror cap 23 fixedly arranged inside the module housing 22, a mirror lock 24 fixedly connected to the mirror cap 23, and a collimating lens 25 connected to the mirror lock 24; The zoom laser irradiation module 4 includes: A zoom fixed lens seat 41, one side of which is connected to a zoom LD seat 42 via a thread, and a plano-convex lens 43 is fixedly disposed on the zoom fixed lens seat 41; Infrared laser diode 31, arranged on the zoom LD seat 42; A zoom movable lens seat 45 is slidably connected to the zoom LD seat 42 and a zoom plano-concave lens 44 is fixedly arranged on one side close to the zoom LD seat 42; A zoom knob 46 is connected to the zoom movable lens holder 45 and is threadedly arranged with the outer shell 1. A zoom transmission rod 47 is arranged on one side of the zoom knob 46; During operation, rotating the zoom transmission rod 47 will drive the zoom knob 46 to rotate inside the outer shell 1, and the zoom knob 46 will drive the zoom movable lens seat 45 and the zoom plano-concave lens 44 to slide horizontally, thereby driving the zoom plano-concave lens 44 away from or close to the plano-convex lens 43, ultimately achieving the zoom function.

[0031] In detail, the red laser module 2 is used for irradiating red laser, the infrared laser module 3 is used for irradiating infrared laser, and the zoom laser irradiation module 4 is a variable-focus infrared laser irradiation module, which is composed of an infrared laser diode 31 and a zoom mechanical structure. The infrared laser diode 31 is used for irradiating infrared laser, and the zoom mechanical structure is used to adjust the forward and backward movement displacement of the infrared laser diode 31 and adjust the size of the irradiation spot. By integrating laser modules with different uses into one, a set of products can meet multiple uses and meet the use requirements in all weather and various complex environments. During use, there will be different environments during the day and at night. The brightness is higher during the day. In order to facilitate the naked eye to find the indication point, the red light laser module 2 can be used for irradiation. At night, it is convenient for night observation and the infrared laser module 3 can be used for irradiation. Both emit parallel light in the product and will not affect the accuracy. At the same time, if there is a need for large-scale irradiation at night and there is a need for concealed functions, the zoom laser irradiation module 4 can be used. By rotating the zoom transmission rod 47, the irradiation focal length can be adjusted, and the irradiated range will change with the adjustment.

[0032] Among them, by combining the red light laser module 2, the infrared laser module 3, and the zoom laser irradiation module 4 together, the user can choose which laser module to use according to different environments such as day or night, so that a set of modules can meet the needs of multiple uses, multiple functions do not require replacement of accessories, and are compact and easy to use.

[0033] like Figure 4-Figure 9 As shown, a laser device has a three-in-one multifunctional laser module, which includes an outer shell 1 and a red laser module 2, an infrared laser module 3, a zoom laser irradiation module 4, a mounting ring 5 and a protective component 6 installed inside the outer shell 1; the mounting ring 5 is fixedly arranged on the outer side of the outer shell 1; the protective component 6 is arranged on the mounting ring 5, and includes a protective ring 61 arranged corresponding to the mounting ring 5, and the protective ring 61 is arranged corresponding to the red laser module 2, the infrared laser module 3, the zoom laser irradiation module 4. A first light-transmitting opening 611, a second light-transmitting opening 612 and a third light-transmitting opening 613 are respectively opened at the positions, and the protective component 6 is respectively rotatably provided with a first light-shielding plate 63, a second light-shielding plate 64 and a third light-shielding plate 65 at the positions corresponding to the first light-transmitting opening 611, the second light-transmitting opening 612 and the third light-transmitting opening 613 through a rotating shaft 62, and a control unit 66 for driving the first light-shielding plate 63, the second light-shielding plate 64 and the third light-shielding plate 65 to rotate synchronously is also provided inside the protective component 6.

[0034] Among them, in the present invention, a protective component 6 is arranged on the outside of the laser module. When the laser module is not needed, the protective ring 61 can be matched with the mounting ring 5, and the first light shielding plate 63, the second light shielding plate 64 and the third light shielding plate 65 can be closed. This can prevent the light outlet of the laser module from being contaminated in harsh environments. When it is needed, the user can directly turn the lever 663 to open the three groups of light shielding plates at the same time, or directly open the protective ring 61 for use, which is convenient and quick.

[0035] Further, if Figure 7 As shown, the control unit 66 includes an inner gear ring 661 rotatably disposed inside the placement groove 614 of the protective ring 61, and an outer gear part 662 is fixedly disposed at one end of the rotating shaft 62 extending into the placement groove 614, and the outer gear part 662 is arranged to transmit to the inner gear ring 661; A lever 663 is fixedly disposed at one end of the inner gear ring 661 , and one end of the lever 663 away from the inner gear ring 661 extends out of the protective ring 61 .

[0036] In detail, when in use, since the inner gear ring 661 is simultaneously connected to the three outer gear parts 662 in transmission, when the user pushes the lever 663 and drives the inner gear ring 661 to rotate inside the placement slot 614, the three outer gear parts 662 will be synchronously driven to rotate, and then the three corresponding rotating shafts 62 will be synchronously driven to rotate. After the three rotating shafts 62 rotate, the first light shielding plate 63, the second light shielding plate 64 and the third light shielding plate 65 will be synchronously driven to rotate, thereby allowing the first light transparent port 611, the second light transparent port 612 and the third light transparent port 613 to leak out, and then the corresponding laser module switch can be turned on for normal use. Similarly, pushing the lever 663 in the opposite direction will cause the first light shielding plate 63, the second light shielding plate 64 and the third light shielding plate 65 to synchronously cover the first light transparent port 611, the second light transparent port 612 and the third light transparent port 613.

[0037] Further, if Figure 7 As shown, light-transmitting plates 67 are fixedly disposed inside the protective ring 61 at positions corresponding to the first light-transmitting opening 611 , the second light-transmitting opening 612 , and the third light-transmitting opening 613 .

[0038] In this way, even if the user opens the first light shading plate 63, the second light shading plate 64 and the third light shading plate 65, due to the setting of the light-transmitting plate 67, the pollutants will not pass through the first light-transmitting port 611, the second light-transmitting port 612 and the third light-transmitting port 613, thereby ensuring the normal use of the red light laser module 2, the infrared laser module 3 and the zoom laser irradiation module 4.

[0039] Further, if Figure 4-Figure 9 As shown, the protection ring 61 and the mounting ring 5 are rotatably arranged, and a torsion spring 615 is arranged on the rotating shaft between the protection ring 61 and the mounting ring 5; A first magnet 51 is fixedly disposed on the upper end of the mounting ring 5 , and a second magnet 616 having a magnetic property opposite to that of the first magnet 51 is disposed on the protection ring 61 at a position corresponding to the first magnet 51 .

[0040] When the user needs to expose the red laser module 2, the infrared laser module 3, and the zoom laser irradiation module 4 to the external environment for direct use, the protective ring 61 can be directly opened. The opened protective ring 61 will be bounced upward under the action of the torsion spring 615 until the second magnet 616 on the protective ring 61 and the first magnet 51 on the mounting ring 5 attract each other. At this time, the protective ring 61 will be fixed on the outside of the mounting ring 5. When closing the protective ring 61 again, the protective ring 61 can be directly pressed to make the protective ring 61 cooperate with the mounting ring 5. Optionally, a sealing ring is fixedly arranged inside the protective ring 61 at a position corresponding to the outer ring of the mounting ring 5. Since a sealing ring is arranged between the protective ring 61 and the mounting ring 5, the stability of the connection between the protective ring 61 and the mounting ring 5 can be guaranteed, and it can be ensured that external water will not enter the interior along the gap between the protective ring 61 and the mounting ring 5.

[0041] Further, if Figure 10-11 As shown, the laser device further includes a cleaning assembly 7, which includes a first water outlet pipe 71, a second water outlet pipe 72, and a third water outlet pipe 73 arranged corresponding to the inner side of the light-transmitting plate 67 (the side of the light-transmitting plate 67 away from the first light-shielding plate 63, the second light-shielding plate 64, and the third light-shielding plate 65), and the first water outlet pipe 71, the second water outlet pipe 72, and the third water outlet pipe 73 are respectively connected to a water supply unit 74; The water supply unit 74 includes a water storage pipe 741, a first water outlet pipe 71, a second water outlet pipe 72, a third water outlet pipe 73, a water injection pipe 742, a sealing plug 743 and a movable rubber ring 744, one end of the water storage pipe 741 is respectively connected with the water supply pipe 741; the water injection pipe 742 is fixedly arranged at the upper end of the water storage pipe 741 and the upper end of the water injection pipe 742 is provided with a sealing plug 743; the movable rubber ring 744 is slidably arranged inside the water storage pipe 741 and the other end is connected with a push rod 745.

[0042] Among them, by setting up the cleaning component 7, when the light-transmitting plate 67 is contaminated, the user can quickly wipe the outside of the light-transmitting plate 67 with hands or other cleaning devices, and for the inside of the light-transmitting plate 67, the cleaning component 7 can be used to quickly clean it (due to the limitation of space size, the operator cannot quickly clean the inside of the light-transmitting plate 67), and there is no need for the user to wipe it, thereby ensuring the normal light output effect of the laser module.

[0043] In detail, when there is enough water stored in the water storage pipe 741, the user pushes the push rod 745 to drive the movable rubber ring 744 to slide inside the water storage pipe 741, and the movable rubber ring 744 will push the water inside the water storage pipe 741 to the first water outlet pipe 71, the second water outlet pipe 72, and the third water outlet pipe 73, and spray it out from the first water outlet pipe 71, the second water outlet pipe 72, and the third water outlet pipe 73 respectively, thereby cleaning the light-transmitting plate 67.

[0044] It should be noted that the water storage pipe 741 is arranged on the outside of the outer shell 1. In this way, when the operator needs to add water to the water storage pipe 741, he only needs to open the sealing plug 743 on the water injection pipe 742, and then pour water into the water injection pipe 742. The water in the water injection pipe 742 will flow to the water storage pipe 741. It should be noted that when adding water, the push rod 745 needs to be stretched to the outermost side first.

[0045] Further, if Fig.10 As shown, the lower ends of the mounting ring 5 and the protective ring 61 are provided with a plurality of through holes 52. Such an arrangement allows the water sprayed from the first water outlet pipe 71, the second water outlet pipe 72, and the third water outlet pipe 73 to be discharged along the through holes 52, thereby preventing water from accumulating inside the mounting ring 5 and the protective ring 61.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
