Illustratively, the second light emitting diodes 421 can be at least two of ultraviolet light emitting diodes, red light emitting diodes, amber light emitting diodes, or green light emitting diodes. By arranging the first light emitting diodes 411 and the second light emitting diodes 421 in the light emitting device 4, when the first light emitting diodes 411 or the second light emitting diodes 421 work alone, the light emitting device 4 can emit the required monochromatic light from the light outlet 211; when the first light emitting diodes 411 and the second light emitting diodes 421 work simultaneously, the light emitted by the two can be combined in the light emitting device 4 and then emitted from the light outlet 211 as the required mixed light.

[0027] In combination Figure 2 and Figure 3As shown in FIG. 4, in a possible implementation, the light emitting device 4 includes at least two optical lenses 43 arranged along the second direction. The first light emitting diode 411, the optical lens 43, and the light outlet 211 are arranged along the second direction in sequence, that is, the light emitted by the first light emitting diode 411 passes through the optical lens 43 and is finally emitted from the light outlet 211.

The angle between the optical lens 43 and the second light emitting diode 421 is 50-60°, that is, the angle between the optical lens 43 and the second direction is 50-60°, so that the light emitted by the second light emitting diode 421 is accurately emitted from the light outlet 211 after being reflected by the optical lens 43. This is beneficial to meeting the various lighting requirements of the light emitting device 4, simplifying the structure of the light emitting device 4, reducing the internal structure complexity of the endoscope main machine 1, and realizing the integrated endoscope main machine 1 with a good ventilation and heat dissipation path.
[0028] Figure 4 FIG. 5 is a structural schematic diagram of an endoscope main machine 1 provided by another embodiment of the present application, which is combined with Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in FIG. 5, in a possible implementation, the housing 2 further includes a back shell 22 arranged opposite to the front shell 21. Along the second direction, the front shell 21 and the back shell 22 are arranged in sequence, that is, the front shell 21 and the back shell 22 are arranged at opposite ends of the endoscope main machine 1 in the length direction. The back shell 22 has a first through hole 221 located in the first mounting area 111 and a second through hole 222 located in the second mounting area 112. The substrate 3 has a plurality of third through holes 31 distributed in the first mounting area 111 and the second mounting area 112. The first through hole 221 and the plurality of third through holes 31 located in the first mounting area 111 form a first ventilation and heat dissipation path, which is used for dissipating the heat of the components in the first mounting area 111, for example, the heat generated by the light emitting device 4. The second through hole 222 and the plurality of third through holes 31 located in the second mounting area 112 form a second ventilation and heat dissipation path, which is used for dissipating the heat of the components in the second mounting area 112, for example, the heat generated by the mainboard 5 when running. By arranging the first through hole 221, the second through hole 222, and the third through hole 31 in the endoscope main machine 1 to form two groups of ventilation and heat dissipation paths extending along the second direction, the endoscope main machine 1 has a short and smooth ventilation and heat dissipation path, which is beneficial to efficiently dissipating the heat of the components and ensuring the working efficiency of the endoscope main machine 1.
[0029] In combination with Figure 2 ,Figure 3 and Figure 4 As shown, in one possible implementation, the light-emitting device 4 includes a first heat sink 47 and a second heat sink 48 disposed along the first direction. The first heat sink 47 is used to absorb heat from the second light-emitting part 42, and the second heat sink 48 is used to absorb heat from the first light-emitting part 41. A first fan 44 and a second fan 45 are respectively disposed at opposite ends of the first heat sink 47 along the second direction.

The first through hole 221, the second fan 45, the first heat sink 47, and the first fan 44 are arranged sequentially along the second direction. The first fan 44 can be used to intake air through the third through hole 31 on the substrate 3, and the second fan 45 can be used to exhaust air to the outside of the endoscope host 1 through the first through hole 221. The heat dissipation process of the second light-emitting part 42 is as follows: the first fan 44 introduces cold air through the third through hole 31, the cold air passes through the first heat sink 47 and carries away the heat absorbed by the first heat sink 47 from the second light-emitting part 42, and the hot air carrying heat is finally discharged to the outside of the endoscope host 1 through the first through hole 221 under the action of the second fan 45, which is conducive to efficiently dissipating the heat generated by the light-emitting device 4 and ensuring the working efficiency of the endoscope host 1.

Along the second direction, the light outlet 211, multiple optical lenses 43, the first light-emitting part 41, the second heat sink 48, the third fan 46, and the fourth through hole 223 are arranged sequentially. The third fan 46 can be used to exhaust air to the outside of the endoscope host 1 through the fourth through hole 223. The heat dissipation process of the first light-emitting part 41 is as follows: cold air enters the receiving cavity 11 through the air inlet on the substrate 3 corresponding to the position of the second heat sink 48. The cold air passes through the bottom of the second heat sink 48 and carries away the heat absorbed by the second heat sink 48 from the first light-emitting part 41. The hot air carrying heat is finally exhausted to the outside of the endoscope host 1 through the fourth through hole 223 under the action of the third fan 46. This is beneficial for efficiently dissipating the heat generated by the light-emitting device 4 and ensuring the working efficiency of the endoscope host 1.

Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, in a possible implementation, the endoscope host 1 further comprises a fourth fan 12, a third heat sink 13 and a fifth fan 14 located at the second mounting area 112. The fourth fan 12 is arranged on the back shell 22 and opposite to the second through hole 222. The fourth fan 12 can be used to discharge the heat inside the endoscope host 1 through the second through hole 222. The substrate 3, the main board 5, the third heat sink 13 and the fifth fan 14 are sequentially arranged along a third direction perpendicular to the plane where the first direction and the second direction are located. Illustratively, the substrate 3, the main body 51 of the main board 5, the third heat sink 13 and the fifth fan 14 can be sequentially stacked. The third heat sink 13 can be used to absorb the heat generated by the main board 5 during operation. The heat dissipation process of the main board 5 is as follows: the fifth fan 14 draws cold air through the third through hole 31, the cold air passes through the third heat sink 13 and carries away the heat absorbed by the third heat sink 13 from the main board 5, and the hot air carrying the heat is finally discharged to the outside of the endoscope host 1 through the second through hole 222 under the action of the fourth fan 12, which is conducive to efficiently discharging the heat generated by the main board 5 and ensuring the working efficiency of the endoscope host 1.
[0032] In combination Figure 2 and Figure 5 As shown, in a possible implementation, the endoscope host 1 further comprises a baffle 7 located between the light emitting device 4 and the main body 51 of the main board 5. The baffle 7 is perpendicular to the first direction and separates the first mounting area 111 from the second mounting area 112. The baffle 7 can be used to electrically isolate the light emitting device 4 from the main body 51 of the main board 5 to avoid current crosstalk between the light emitting device 4 and the main body 51. The baffle 7 can also be used to carry the light emitting device 4 to allow the light emitting device 4 to be detachably assembled in the first mounting area 111, which is conducive to reducing the complexity of the internal structure of the endoscope host 1 and realizing the integrated endoscope host 1 with a good ventilation and heat dissipation path.
[0033] In combination Figure 2 and Figure 5 As shown, in a possible implementation, the endoscope host 1 further comprises an isolation plate 8 located at the second mounting area 112. The isolation plate 8 is stacked with the main board 5 and the substrate 3, that is, a part of the isolation plate 8 is laid on the substrate 3 and another part of the isolation plate 8 is laid on the main body 51. The isolation plate 8 is located between the front shell 21 and the main board 5, and there is a gap between the isolation plate 8 and the front shell 21. A plurality of third through holes 31 are arranged on the gap, that is, the plurality of third through holes 31 are located between the front shell 21 and the isolation plate 8. The isolation plate 8 can be used to separate the high-voltage electrical part and the low-voltage electrical part of the main board 5, which simplifies the internal structure of the endoscope host 1 while ensuring the normal operation of the main board 5, and is conducive to realizing the integrated endoscope host 1 with a good ventilation and heat dissipation path.
[0034] In combination Figure 2 and Figure 5As shown, in one possible implementation, a display screen 212 is also provided on the outer side of the front shell 21, and the light outlet 211 and the display screen 212 are arranged sequentially along the first direction. The isolation plate 8 is located between the display screen 212 and the motherboard 5, that is, the motherboard 5, the isolation plate 8, and the display screen 212 are arranged sequentially along the second direction. The display screen 212 can be a touch screen, and the user can directly input control commands through the display screen 212 to realize human-computer interaction. For example, when the user inputs the corresponding control command, the display screen 212 can display menu switching or pop up parameter setting windows, etc. The user can then further set the parameters and finally control the various working processes of the endoscope host 1 through the display screen 212. By placing the isolation plate 8 between the display screen 212 and the motherboard 5, current leakage from the motherboard 5 to the front shell 21 can be prevented when the user touches the display screen 212. This simple setting ensures the safety of the endoscope host 1 and avoids increasing the complexity of the internal structure of the endoscope host 1.
[0035] Combination Figure 2 and Figure 5 As shown, in one possible implementation, the endoscope host 1 further includes an air pump module 9 spanning the second mounting area 112 and the third mounting area 113. The air pump module 9 can be used to deliver gas and liquid. During the use of the endoscope, since the endoscope probe needs to be inserted into the human body, the presence of folds in the intestines, gastrointestinal fluid, or other objects inside the body can easily obstruct the endoscope probe, thus affecting the imaging effect. The air pump module 9 provides liquid and gas to the endoscope probe, thereby achieving the purpose of flushing the endoscope probe and clearing the intestines, keeping the endoscope probe clean and gently pushing open the intestines, which is beneficial to the imaging of the endoscope host 1. The air pump module 9 is detachably connected to the base plate 3 via a platform with four pins, that is, the air pump module 9 is suspended relative to the base plate 3. Along the third direction, the air pump module 9 is provided with a plurality of third through holes 31 at one end near the substrate 3. This allows cold air from outside the endoscope host 1 to enter through the plurality of third through holes 31 and pass through the gap between the air pump module 9 and the substrate 3 to enter the heat dissipation path to remove the heat from the motherboard 5. This facilitates the efficient removal of the heat generated by the motherboard 5 and ensures the working efficiency of the endoscope host 1.
[0036] Combination Figure 2 and Figure 5As shown, in one possible implementation, the power supply module 6 includes a power supply 61 and a filter 62, which are disposed opposite each other in the third mounting area 113 along the second direction. The power supply 61, the filter 62, and the motherboard 5 are electrically connected in sequence. The filter 62 can be used to suppress noise and high-frequency harmonics generated by the switching power supply 61, thereby reducing the leakage current of the power supply 61 and providing better power to the motherboard 5. By placing the power supply 61 and the filter 62 in the third mounting area 113, that is, placing the power supply 61 and the filter 62 on the side of the motherboard 5 away from the light-emitting device 4, the ventilation and heat dissipation path of the motherboard 5 is kept unobstructed, which is conducive to efficiently dissipating the heat of the motherboard 5 and ensuring the working efficiency of the endoscope host 1.
[0037] In summary, by arranging the light-emitting device, power supply module, and motherboard in an orderly manner in the first mounting area, the second mounting area, and the third mounting area, this embodiment of the application achieves an integrated endoscope host with good ventilation and heat dissipation, ensuring the heat dissipation efficiency of the endoscope host and facilitating its normal operation.
