In the prior art, the optical fiber light guide interface seat of the endoscope is a cylindrical independent component, a light emitting component is installed at the rear end of the optical fiber light guide interface seat, and in use, an optical fiber joint is inserted into the optical fiber light guide interface seat and fixed, and a heat sink of another independent component is connected at the rear end of the optical fiber light guide interface seat. The optical fiber light guide interface seat and the heat sink are packaged together in the shell of the endoscope, and in use, the optical fiber joint is inserted into the optical fiber light guide interface seat to transmit the light waves generated by the light emitting component into the optical fiber and emit the light waves out of the light guide outlet end.

[0003] Since the light emitting component generates a large amount of heat, the rear part of the optical fiber light guide interface seat is connected with the heat dissipation component, the heat dissipation component absorbs the heat and diffuses the heat out of the rear part of the endoscope shell.

[0004] The above structure has the following disadvantages:

[0005] 1. Since the heat sink and the optical fiber light guide interface seat are separately arranged (only the light emitting component is in contact with the heat sink), the volume of the combination of the optical fiber light guide interface seat and the heat sink is large.

[0006] 2. Since the optical fiber light guide interface seat and the heat sink are fixedly installed in the shell of the endoscope, the combination cannot be used as an independent endoscope light source, and cannot be replaced and used in different endoscopes. SUMMARY

[0007] The utility model wants to solve the technical problem to provide a kind of integrated endoscope light source device with light weight, small volume, can be conveniently disassembled and used as independent endoscope light source machine.

[0008] To solve the above technical problem, the technical scheme adopted by the present application is:

[0010] The left side and the right side of the heat sink are finned heat sinks with heat pipes extending from the rear end to the front end.

[0011] The heat dissipation fan is a centrifugal disc fan, which is built in a shell, and a deflector is arranged on the air outlet of the front end of the shell to guide the air flow generated by the heat dissipation fan to the light source assembly.

[0012] The light source assembly, the heat dissipation fan and the electric control board are assembled in a rectangular shell, a baffle with a fiber mounting through hole is arranged on the front end surface of the shell, a clamping piece for fastening a fiber light guide plug is arranged in the fiber mounting through hole, and a heat dissipation hole is arranged on the side wall of the shell opposite to the heat dissipation plate.

[0013] An operation interface for turning on or off the light source device is arranged on the top surface of the shell.

[0014] The length, width and height of the shell are (15cm - 25cm) x (4cm-7cm) x (2cm-4cm).

[0015] Compared with the prior art, the utility model integrates the fiber light guide interface seat, the radiator, the electric control board, the heat dissipation fan and the electric control board in the independent shell to form a portable endoscope light source complete machine product, and can also be quickly plugged and replaced between different endoscope complete machines. The fiber light guide interface seat is built in the radiator, and the radiator is not only a quick import interface of the fiber, but also is beneficial to reducing the volume of the device, so that the utility model has the advantages of small volume, light weight, convenient carrying, convenient maintenance, low manufacturing cost and the like.

[0024] like Figures 1-6 As shown, the endoscope light source device 1 of this utility model integrates the fiber optic light guide interface 4, heat sink 3, electronic control board 8, and cooling fan 7 into a housing 2 to form a portable endoscope light source device. When needed, it can also be used in series between different endoscope devices (that is, when the light source system in other endoscope devices has a problem, the light source device of this utility model can be quickly replaced).

[0025] It has two usage methods: First, it can be installed inside the endoscope unit, and its internal control board 8 is electrically connected to the main control board inside the endoscope unit through a quick-connect connector; Second, it can be used as an external, independent endoscope light source unit with an operating interface 21, and its internal control board 8 is electrically connected to the main control board inside the endoscope unit through a quick-connect connector. This makes it convenient to use, maintain, and carry when going out.

[0026] It can be used in medical endoscopes and in industrial detection equipment.

[0027] The endoscope light source device 1 of this utility model includes the following two types:

[0028] 1. An externally usable standalone product (can be used as a complete endoscope light source unit).

[0029] like Figures 1-3 As shown, it includes a housing 2, a light source assembly, a cooling fan 7, an electronic control board 8, and corresponding connecting wires and quick-connect plugs.

The direction inside the paper is left and the direction outside the paper facing the observer is right (the same below). There are heat dissipation holes on its rear end face. Its left and right sides have multiple sets of alternating grooves and ridges 22 extending from front to back. The setting of the grooves and ridges 22 increases the heat dissipation area and plays a positive role in quickly dissipating the heat inside the casing 2 to the external environment.

[0032] 2) The light source assembly comprises a fiber light guide interface seat 4 and a heat sink 3, the fiber light guide interface seat 4 is a central passage arranged in the heat sink 3, the front port of the central passage is opposite to the fiber mounting through hole 5, and the light emitting component 6 is arranged at the rear end of the central passage, the light emitted by the light emitting component 6 is received by the fiber light guide joint inserted into the fiber light guide interface seat 4 and then output by the external fiber.

[0033] The light emitting component is preferably an LED light source assembly (i.e. a lamp bead + a copper substrate), which is arranged in a reverse mounting and heat conduction mode, that is, the front of the light source assembly (the light emitting direction) is connected to the heat sink. The connection between the LED light source assembly and the front heat sink can be fixed connection by screws or welding connection, so that the light source assembly and the heat sink are connected into one body, which is more conducive to heat conduction and heat dissipation, and the whole device is more stable.

[0034] The heat sink 3 has a rectangular body shape, the left side and the right side of the heat sink 3 are provided with fin-shaped heat dissipation plates 31 extending from the rear end to the front end, and a heat pipe is embedded on each heat dissipation plate 31, so that the heat generated by the light emitting component 6 is quickly transmitted and discharged from the rear to the front through the heat pipe.

[0035] 3) The heat dissipation fan 7 is arranged on the rear side of the heat sink 3 opposite to the light emitting component 6, which is a centrifugal disc fan (i.e. the blades are arranged along the periphery of the rotating disc at intervals, and when rotating, the air flow generated by the blades is diffused in all directions), which is arranged in a shell, the left side, the right side and the rear side of the shell are closed surfaces, and the front side of the shell is an open port, which is opposite to the light emitting component 6, in order to guide the air flow generated by the heat dissipation fan 7 to blow on the light emitting component 6 and flow along the left side and the right side of the heat sink 3 from the rear to the front, a wind deflector 71 is arranged on the open port, the central part of the wind deflector 71 is an air outlet hole 72, and the edge area of the wind deflector 71 is a shielding plate for preventing air leakage.

[0036] 4) An operation interface 21 for opening or closing the endoscope light source device 1 of the utility model is arranged on the top surface of the shell 2, the operation interface 21 comprises a liquid crystal or LED display panel, a button for turning on the light emitting component 6, a button for adjusting the brightness of the light source, an actual operation time value prompt mark and the like.

[0037] 5) The electric control board 8 comprises an anti-reverse circuit, a filter circuit, a dimming circuit and the like.

[0038] 6) Connection wires and quick plug connectors are used for electrically connecting the electric control board 8 with the main control board in the endoscope, the light emitting component 6, the heat dissipation fan 7, the operation interface 21 and the power supply in the endoscope respectively.

[0039] 2, a product that can be quickly plugged into the endoscope

[0040] The product can be used as a separate light source component arranged in the endoscope.

[0041] As shown in Figures 4-6 The difference between the two is that the former does not have the operation interface 21, and the internal structure and components are basically the same. The connecting wires and quick connectors are used to electrically connect the electric control board 8 to the main control board, the light-emitting component 6, the cooling fan 7 and the power supply in the endoscope.

[0042] The buckle or clamping structure is provided on the outer surface of the casing 2 to quickly fix the light-emitting device in the endoscope.
