[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In the related art, an endoscope generally includes an endoscope cold light source host, a light guide, an endoscope, an endoscope camera, cables, a camera host, a display, and a video connection cable. The endoscope includes an illumination light path and an imaging light path. The illumination light path is connected to the light guide to irradiate the illumination light transmitted by the endoscope cold light source host to a specific part of the inspection object. The imaging light path is connected to the endoscope camera to obtain the light signal reflected or excited by the specific part of the inspection object and transmit it to the endoscope camera.
[0029] The camera host is connected to the endoscope camera head through a cable, and the white light signal and fluorescent signal generated by the endoscope camera head are transmitted to the camera host through the cable for processing. The cable can be an optical communication cable, such as an optical fiber; the endoscope camera head converts the image signal (electrical signal) into an optical signal, which is transmitted to the camera host through the cable, and the camera host converts the optical signal into an electrical signal (image signal). The camera host is connected to the monitor through a video cable to send the image signal to the monitor for display.
[0030] An endoscope cold light source host is usually provided with an LED lamp, and its temperature may exceed 65°C during operation. In order to cool down the LED, etc., an embodiment of the utility model provides an endoscope cold light source host and an endoscope, wherein the host comprises a housing, a light-emitting component, a heat-conducting component, a heat sink and a micro-blower, wherein the heat generated by the light-emitting component during operation can be transferred to the heat sink via the heat-conducting component, and then the heat sink is blown by the micro-blower to achieve air cooling, thereby finally reducing the temperature of the light-emitting component. Figures 1 to 7 The figure further describes the endoscope cold light source host and the endoscope in this embodiment.
[0031] Specifically, if Figure 1 As shown, the endoscope cold light source host in this embodiment includes: a shell 1, a light-emitting component 2, a heat-conducting component 3, a heat sink 4 and a micro-blower 5, the shell 1 has a accommodating space, and the light-emitting component 2, the heat-conducting component 3, the heat sink 4 and the micro-blower 5 are all arranged in the accommodating space.
[0032] One end of the heat conducting component 3 is connected to the light emitting component 2 , and the other end is connected to the heat sink 4 . The micro blower 5 is arranged on the side of the heat sink 4 , and the micro blower 5 can blow air to the heat sink 4 .
[0033] Exemplarily, the shell 1 can be made of a plastic material, and the shell 1 can be constructed as a flat structure according to usage requirements. The shell 1 has a storage space inside, and electrical components for providing a light source can be installed in the storage space. For example, in this embodiment, the light-emitting component 2 includes an LED lamp that can provide a light source, and the light-emitting component 2 is arranged in the storage space.
[0034] Furthermore, in order to directly and effectively cool the light-emitting component 2, a heat-conducting component 3, a heat sink 4 and a micro-blower 5 are also provided in the accommodation space.
[0035] The two ends of the thermal conductive component 3 are respectively connected to the light emitting component 2 and the heat sink 4. The thermal conductive component 3 can be made of a metal material capable of transferring heat, such as copper. The thermal conductive component 3 can effectively transfer the heat generated during the operation of the light emitting component 2 to the heat sink 4.
[0036] The heat sink 4 can dissipate the heat from the heat-conducting component 3 into the surrounding air. The heat sink 4 can be constructed into a plate, sheet, or multiple sheet shapes according to the size of the space reserved in the accommodation space. The heat sink 4 can be made of materials such as copper or aluminum alloy.
[0037] The micro blower 5 is installed on the side of the heat sink 4. After the heat sink 4 receives the heat from the light-emitting component 2, the micro blower 5 can blow air to the heat sink to accelerate the heat dissipation effect of the heat sink 4 by air cooling.
[0038] In actual use, when the endoscope cold light source host needs to provide light to the outside, the light-emitting component 2 can be kept in working state, and the micro-blower 5 can be kept in operation to continuously blow air to the heat sink 4. During this process, the heat generated by the light-emitting component 2 can be promptly transferred to the heat sink 4 through the heat-conducting component 3, and under the air-cooling effect of the micro-blower 5, the heat can be dissipated into the air faster, thereby achieving effective cooling of the light-emitting component 2.
[0039] Therefore, in the endoscope cold light source host of this embodiment, with the help of the heat conductive component 3, the heat sink 4 and the micro blower 5, the light emitting component 2 can be effectively cooled to prevent the temperature of the LED lamp in the light emitting component 2 from exceeding 65°C, prevent the lamp beads from experiencing serious light decay, and reduce safety hazards.
[0040] Furthermore, since the heat sink 4 is disposed in the accommodation space, in order to effectively transfer the heat dissipated from the heat sink 4 to the air to the outside of the housing 1 and avoid excessively high internal temperature of the housing 1, as shown in FIG. Figure 2 and Figure 3 As shown, the shell 1 is provided with a first through hole 11 and a second through hole 12, the air inlet of the micro blower 5 faces the first through hole 11, the air outlet of the micro blower 5 faces the second through hole 12, and the heat sink 4 is arranged between the air outlet of the micro blower 5 and the second through hole 12.
[0041] It can be understood that the micro blower 5 has an air inlet and an air outlet. The micro blower 5 can inhale air from the air inlet and blow air from the air outlet during operation.
[0042] The first through hole 11 and the second through hole 12 on the housing 1 may be a plurality of through holes disposed in different areas and arranged in a lattice.
[0043] During actual operation, the micro blower 5 can suck air from the external environment into the accommodation space of the shell 1 through the first through hole 11 on the shell 1, and then blow the air toward the heat sink 4, so that the air receives the heat dissipated by the heat sink 4. Finally, the hot air can leave the accommodation space of the shell 1 through the second through hole 12 on the shell 1 and reach the external environment.
[0044] Therefore, through the above-mentioned setting method, air circulation can be achieved between the external environment and the internal storage space of the shell 1, so that the heat generated by the light-emitting component 2 can be transferred to the external environment in time, avoiding the temperature of the storage space inside the shell 1 to achieve better heat dissipation effect.
[0045] In a specific embodiment, Figure 2 and Figure 3 As shown, the shell 1 includes a support plate 13 and a side plate 14 , the side plate 14 is vertically connected to the edge of the support plate 13 , the first through hole 11 is arranged on the support plate 13 , the second through hole 12 is arranged on the side plate 14 , and the micro blower 5 is fixedly mounted on the support plate 13 .
[0046] Exemplarily, the support plate 13 may be a plate-like structure with a certain thickness, and the side plate 14 is connected to the edge of the support plate 13 and extends along the thickness direction of the support plate 13. In actual production, the support plate 13 and the side plate 14 may be integrally formed by injection molding or the like.
[0047] The support plate 13 is provided with a plurality of screw mounting holes on the inner side facing the accommodating space, and the micro blower 5 can be fixedly mounted on the support plate 13 by means of screws and other structures, and the air inlet of the micro blower 5 can fully cover the first through hole 11 provided on the support plate 13.
[0048] Accordingly, the heat sink 4 can be disposed at a position close to the second through hole 12 of the side plate 14 and fixedly mounted on the support plate 13 by means of screws or the like.
[0049] Therefore, by respectively arranging the first through hole 11 and the second through hole 12 on the support plate 13 and the side plate 14 which are perpendicular to each other, "remote heat dissipation" can be achieved, that is, cold air from the outside can enter from the back of the main unit, and the hot air after heat exchange can be blown out from the side without confusion, and the heat dissipation efficiency is high.
[0050] In this embodiment, in order to output the light source externally, Figures 1 to 3 As shown, the endoscope light source device further includes a socket 6 , which is disposed in the accommodating space, a socket portion of the socket 6 is connected to the housing 1 , and the light emitting component 2 is disposed at the rear of the socket 6 .
[0051] Exemplarily, a plug hole is provided on the side plate 14, and the socket portion of the socket 6 corresponds to the position of the plug hole. The socket 6 can be fixedly mounted on the support plate 13 by means of screws or other structures. The light emitting component 2 is provided at the tail of the socket 6, and the light emitting component 2 can transmit the generated light beam to the socket 6.
[0052] In actual use, the external light guide can pass through the plug hole on the side panel 14 and be plugged into the socket portion of the socket 6. After that, the light beam generated by the light emitting component 2 can be transmitted to the light guide and finally delivered to the endoscope.
[0053] In a specific embodiment, Figures 1 to 4 As shown, a light-through hole 61 is provided at the tail of the socket 6, and the light-emitting component includes a lamp board and an LED lamp. The LED lamp is arranged on the lamp board, and the lamp board is arranged at the tail of the socket, and the LED lamp faces the light-through hole at the tail of the socket.
[0054] According to the imaging requirements of the light source, in this embodiment, the light-emitting component 2 may include a first light board 21 and a second light board 22, the first light board 21 is provided with a first LED lamp 23, the second light board 22 is provided with a second LED lamp 24, the first light board 21 and the second light board 22 are arranged at the rear of the socket 6, and the first LED lamp 23 and the second LED lamp 24 are both facing the light-through hole 61 at the rear of the socket 6.
[0055] For example, in this embodiment, if Figure 4As shown, a circuit connection board is provided at the bottom of the socket 6, and pins for connecting the light guide and transmitting electrical signals and light-through holes 61 for transmitting the light beam are provided on the circuit connection board. There are two light-through holes 61, and the two light-through holes 61 are respectively arranged on both sides of the pins in the width direction of the circuit connection board.
[0056] Based on this, Figure 5 and Figure 6 As shown, two first LED lamps 23 spaced apart from each other are disposed on the first lamp board 21 , and two second LED lamps 24 spaced apart from each other are disposed on the second lamp board 22 .
[0057] Furthermore, if Figure 1 and Figure 2 As shown, the first light board 21 and the second light board 22 can be arranged perpendicularly to each other at the tail of the socket 6, wherein the first light board 21 can be arranged at the rear of the socket 6 in parallel with the circuit connection board, and the second light board 22 can be arranged at the side of the socket 6 perpendicularly to the circuit connection board, and the two first LED lamps 23 and the two second LED lamps 24 correspond one by one to the positions of the two light holes 61 respectively.
[0058] In other embodiments, according to the imaging and transmission requirements of the light source, the first light board 21 and the second light board 22 may be respectively provided with different numbers and models of LED lights.
[0059] In order to dissipate heat from the lamp panel, the heat conduction component includes a heat conduction pipe, which is a sintered heat pipe. One end of the heat conduction pipe is connected to the light-emitting component, and the other end is connected to the heat sink.
[0060] Specifically, in this embodiment, if Figure 1 and Figure 2 As shown, the heat conduction assembly 3 includes a first heat conduction pipe 31 and a second heat conduction pipe 32. One end of the first heat conduction pipe 31 is connected to the first lamp board 21, and the other end is connected to the heat sink 4. One end of the second heat conduction pipe 32 is connected to the second lamp board 22, and the other end is connected to the heat sink 4.
[0061] For example, the sintered heat pipe has excellent thermal conductivity, and the first heat pipe 31 and the second heat pipe 32 can both be round sintered heat pipes. Thus, the heat generated by the first lamp board 21 can be transferred to the heat sink 4 via the first heat pipe 31, and the heat generated by the second lamp board 22 can be transferred to the heat sink 4 via the second heat pipe 32.
[0062] Furthermore, in order to facilitate installation and heat transfer, the heat conduction component also includes a mounting seat, which is made of metal copper, and the heat conduction pipe is connected to the light-emitting component via the mounting seat.
[0063] Specifically, in this embodiment, if Figure 1 , Figure 2 and Figure 7 As shown, the heat conducting assembly 3 may further include a first mounting seat 33 and a second mounting seat 34 , the first heat conducting pipe 31 is connected to the first lamp board 21 via the first mounting seat 33 , and the second heat conducting pipe 32 is connected to the second lamp board 22 via the second mounting seat 34 .
[0064] Exemplarily, the first mounting seat 33 and the second mounting seat 34 can both be made of metal copper. At this time, the heat on the first lamp board 21 can be transferred to the first heat pipe 31 via the first mounting seat 33, and the heat on the second lamp board 22 can be transferred to the second heat pipe 32 via the second mounting seat 34.
[0065] In one embodiment, in order to achieve effective connection between the various components, the first mounting seat 33 and the first lamp board 21 are connected via bolts, and the first mounting seat 33 and the first heat pipe 31 are connected via laser welding. Similarly, the second mounting seat 34 and the second lamp board 22 are connected via bolts, and the second mounting seat 34 and the second heat pipe 32 are connected via laser welding.
[0066] In one embodiment, in order to improve the heat transfer effect between the mounting base and the light board, a thermal conductive adhesive is filled between the mounting base and the light emitting component.
[0067] For example, in this embodiment, the space between the first mounting seat 33 and the first lamp board 21 is filled with thermal conductive adhesive, and the space between the second mounting seat 34 and the second lamp board 22 is filled with thermal conductive adhesive.
[0068] Therefore, by filling the thermal conductive adhesive, the heat on the lamp board can be transferred to the mounting base in a timely and effective manner, thereby preventing the temperature of the LED lamp on the lamp board from being too high.
[0069] In addition, in this embodiment, the heat sink 4 includes a plurality of copper sheets arranged in sequence at intervals. Figure 1 and Figure 2 As shown, the end of the first heat conducting pipe 31 and the end of the second heat conducting pipe 32 are both connected to a plurality of copper sheets.
[0070] It can be understood that setting up multiple copper sheets can increase the contact area with the air, thereby improving the heat dissipation effect. The end of the first heat pipe 31 and the end of the second heat pipe 32 can be connected to multiple copper sheets to ensure that the heat on the heat pipe can be effectively transferred to the copper sheets.
[0071] In addition, as described above, this embodiment also includes an endoscope, which includes the endoscope cold light source host described in the above embodiment.
[0072] Therefore, the endoscope cold light source host in this embodiment has the following advantages:
[0073] The endoscope cold light source host in this embodiment includes: a shell, a light-emitting component, a heat-conducting component, a heat sink and a micro-blower. The light-emitting component, the heat-conducting component, the heat sink and the micro-blower are all arranged in the accommodating space of the shell, and the light-emitting component, the heat-conducting component and the heat sink are connected in sequence. Thus, during the operation of the light-emitting component, the heat-conducting component can transfer the heat generated by the light-emitting component to the heat sink in a timely manner, and the micro-blower can air-cool the heat sink, and finally the light-emitting component can be effectively cooled, so as to avoid the temperature of the LED lamp in the light-emitting component exceeding 65°C, prevent the lamp beads from having serious light decay, and reduce safety hazards. Moreover, the light-emitting component, the heat-conducting component and the heat sink occupy a small space and can be installed in an environment with limited space.
