Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to a slide scanner with a high-efficiency heat dissipation function. Background Art

[0002] Medical devices are tools, instruments or equipment used for medical purposes, designed to help medical staff diagnose, treat, monitor or support patients' healthcare. These devices are widely used in the medical industry, including hospitals, clinics, laboratories, etc.

[0003] A slide scanner is a medical device used to digitize slides, usually slides of tissue sections or cell specimens. These scanners convert the tissue structure or cell information on the slide into digital images through high-resolution optical systems and image sensors, which can be stored, analyzed and shared through computer systems, providing doctors, pathologists or other medical professionals with more convenient and accurate diagnostic and research tools.

[0004] When the internal electronic components of the slide scanner are working, a certain temperature will be generated. When the existing slide scanners dissipate the heat of the internal electronic components, most of them use cooling fans to dissipate the heat of the internal parts. However, when the internal electronic components are used for a long time, the temperature is too high and the heat can only be dissipated by the rotation of the cooling fan. The heat dissipation effect is poor and efficient heat dissipation cannot be performed. When the heat is dissipated, some dust will enter the interior of the shell and easily adhere to the surface of the electronic components. It is necessary to use a filter to block it. However, when installing the filter, bolts are usually used and then special tools are used to install it on the inner wall of the computer, which is troublesome and inconvenient to disassemble and repair later.

Obviously, the described embodiments are only 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.

[0034] Reference Figure 1-Figure 3 The utility model provides an embodiment: a slide scanner with efficient heat dissipation function, including a shell 1, the outer side wall of the shell 1 is hinged with two groups of side sealing plates 2, the bottom ends of the two groups of side sealing plates 2 are hinged at the bottom end of the shell 1, and the electronic components inside the shell 1 can be efficiently dissipated by opening the two groups of side sealing plates 2. The outer wall of the shell 1 is provided with a cooling fan 4, and the cooling fan 4 is a prior art. The electronic components inside the shell 1 are cooled by the rotation of the cooling fan 4. At the same time, the ventilation holes opened on the surface of the side sealing plates 2 are used to achieve a convection effect, so that the temperature generated by the internal electronic components is blown out.

[0035] See also Figure 3 and Figure 4The top of the outer wall of the shell 1 is elastically connected with a rotating block 3 through a volute spring 8. The rotating block 3 is rotatably connected to the inner wall of the top of the shell 1. The connecting rod 9 penetrates and is rotatably connected to the inner wall of the top of the shell 1. The limiting wheel 12 is rotatably connected to the inner wall of the top of the shell 1. The inner wall of the top of the shell 1 is provided with a space that fits the rotation of the limiting wheel 12, so that the limiting wheel 12 will not be blocked by the inner wall of the top of the shell 1 when it rotates synchronously with the connecting rod 9. The fixed block 5 is fixedly connected to the outer wall of the side sealing plate 2. One end of the volute spring 8 is fixedly connected to the top of the outer wall of the shell 1, and the other end of the volute spring 8 is fixedly connected to the top of the inner wall of the rotating block 3. When the rotating block 3 rotates, the volute spring 8 will produce elastic changes. At the same time, every time the rotating block 3 rotates, the limiting wheel 12 will rotate synchronously with it, thereby being limited by the limiting block 1 1 is engaged, until the limit block 11 is moved to cancel the engagement of the limit wheel 12, the rotating block 3 will be affected by the elastic change of the spiral spring 8, and it, the limit wheel 12 and the connecting rod 9 will be synchronously restored to the initial position, the top of the inner wall of the rotating block 3 is fixedly connected with the connecting rod 9, and the surface of the connecting rod 9 is fixedly connected with the limit wheel 12. The rotating block 3, the connecting rod 9 and the limit wheel 12 are integrated into one body, and the connecting rod 9 and the limit wheel 12 can be driven to rotate synchronously by rotating the rotating block 3. A limiting mechanism is provided on the inner wall of the top of the shell 1, and two groups of wire groups 13 are wound around the outer wall of the bottom end of the connecting rod 9. The wire group 13 is rotatably connected to the fixed block 5 away from the end connected to the connecting rod 9. By rotating the connecting rod 9, the wire group 13 is wound or stretched and unfolded, so that it drives the fixed block 5 to move synchronously.

[0036] Reference Figure 6-Figure 7 The outer wall of the side sealing plate 2 is fixedly connected with two sets of upper and lower mounting seats 6, and the inner wall of the mounting seat 6 is slidably connected with a filter screen 7. The inner walls of the upper and lower mounting seats 6 are provided with guide grooves, and the filter screen 7 is slidably connected inside the guide grooves. The inner wall of the mounting seat 6 is provided with a clamping mechanism, and the clamping mechanism includes a wedge 14, and the wedge 14 is elastically connected to the inner wall of the mounting seat 6 through a return spring 15. One end of the return spring 15 is fixedly connected to the inner wall of the mounting seat 6, and the other end of the return spring 15 is fixedly connected to the surface of the wedge 14. When the filter screen 7 is installed, its outer wall will squeeze the inclined surface of the wedge 14, and push it outward from the inner wall of the mounting seat 6 until the filter screen 7 is completely installed to the mounting seat. When the filter screen 7 is moved to the inner wall of the mounting seat 6, the wedge block 14 will be elastically acted upon by the reset spring 15, and will be restored to its initial position to be plugged into the inside of the through hole 16 at the current position of the filter screen 7, thereby fixing the position of the filter screen 7. The wedge block 14 is slidably connected to the inner wall of the mounting seat 6, and a protrusion is provided on the surface of the wedge block 14. The protrusion allows the wedge block 14 to move only on the inner wall of the mounting seat 6 and cannot be separated from the inner wall. The wedge block 14 is engaged with the inside of the through hole 16, and the engagement between the two fixes the filter screen 7 to the inner wall of the mounting seat 6, thereby preventing the filter screen 7 from being separated from the inner wall of the mounting seat 6 during use. The outer wall of the filter screen 7 is provided with a through hole 16.

[0037] Reference Figure 3-Figure 5 The limiting mechanism includes a limiting block 11, the shape of which corresponds to the rack on the surface of the limiting wheel 12. The limiting block 11 is elastically connected to the inner wall at the top of the shell 1 through a limiting spring 10. One end of the limiting spring 10 is fixedly connected to the outer wall of the limiting block 11, and the other end of the limiting spring 10 is fixedly connected to the inner wall at the top of the shell 1. When the limiting wheel 12 rotates, the arc surface of the rack on its surface squeezes the arc surface of the limiting block 11 and squeezes it to move on the inner wall at the top of the shell 1 until the limiting wheel 12 When the next set of racks is in place, the limit block 11 will be elastically acted upon by the limit spring 10, restoring it to its initial position to contact the back of the rack at the current position, thereby fixing the position of the limit wheel 12. The limit block 11 is slidably connected to the inner wall at the top of the shell 1. A plurality of racks are arranged on the surface of the limit wheel 12. The limit block 11 is engaged with the racks, and the engagement between the two fixes the rotation position of the limit wheel 12, so that it can only rotate clockwise but not counterclockwise.

[0038] Working principle: First, when the electronic components inside the shell 1 are working, a certain temperature will be generated. The internal temperature will be extracted from the inside through the rotation of the cooling fan 4, and convection will be achieved through the ventilation holes opened on the surface of the side sealing plate 2. When the temperature of the internal electronic components is too high and the cooling fan 4 cannot meet its heat dissipation needs, the rotating block 3 can be rotated to make the connecting rod 9 and the limiting wheel 12 at its bottom rotate synchronously. When the rotating block 3 rotates, the volute spring 8 on its inner wall will produce elastic changes. At the same time, when the limiting wheel 12 rotates, the arc surface of the rack on its surface will squeeze the limiting block The arc surface of 11 is squeezed and moved on the inner wall of the top of the shell 1 until it is at the lower group of racks of the limiting wheel 12. The limiting block 11 is elastically acted upon by the limiting spring 10 to restore it to its initial position to contact the back of the rack at the current position, thereby fixing the position of the limiting wheel 12. This process is repeated until the lengths of the upper and lower groups of wires 13 wound around the surface of the connecting rod 9 change. At the same time, when the length of the wires 13 is extended, the side sealing plates 2 on both sides are opened, so that the temperature of the electronic components inside the shell 1 can be dissipated outward from the gaps opened on both sides, thereby achieving a better heat dissipation effect.

[0039] When the two sets of side sealing plates 2 need to be closed, the limit block 11 can be moved to disengage it from the clamping connection with the limit wheel 12. At this time, the rotating block 3 will be affected by the elastic action of the spiral spring 8, and it, the limit wheel 12 and the connecting rod 9 will be restored to the initial position, so that the two sets of wire groups 13 are wound up, thereby driving the two sets of side sealing plates 2 to close and contact the outer wall of the shell 1 again, thereby closing the gaps opened on both sides.

[0040] At the same time, when it is necessary to replace the filter screen 7 at the side sealing plate 2, the wedge block 14 can be directly pulled out to disengage it from the through hole 16 of the filter screen 7, so that the filter screen 7 can be pulled out from the inner wall of the mounting seat 6 to replace it. At this time, the wedge block 14 is released and it will be elastically acted upon by the return spring 15 to restore it to its original position. When replacing the new filter screen 7, its outer wall will squeeze the inclined surface of the wedge block 14 and push it outward from the inner wall of the mounting seat 6 until the filter screen 7 is completely installed to the inner wall of the mounting seat 6. The wedge block 14 will be elastically acted upon by the return spring 15 to restore it to its original position to be plugged into the inside of the through hole 16 at the current position of the filter screen 7, thereby fixing the position of the filter screen 7.

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 make equivalent substitutions for some of the technical features therein.
