[0032] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0033] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present utility model. In addition, the present utility model may repeat reference numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0034] For ease of description, spatially relative relationship terms may be used in the text to describe the relative position relationship or movement of one element or feature shown in the figure relative to another element or feature. These relative relationship terms are, for example, "inside", "outside", "inner side", "outer side", "below", "beneath", "above", "upper", "front", "rear", etc. Such spatially relative relationship terms are intended to include different orientations of the device in use or operation in addition to the orientations depicted in the figure. For example, if the device in the figure undergoes a position flip or attitude change or movement state change, then these directional indications will change accordingly. For example, an element described as "below other elements or features" or "beneath other elements or features" will then be oriented as "above other elements or features" or "upper other elements or features". Therefore, the example term "below" may include both upper and lower orientations. The device may be oriented otherwise (rotated 90 degrees or in other directions) and the spatially relative relationship descriptors used in the text are interpreted accordingly.

[0035] As Figures 1 to 4 shown, in a first aspect, an embodiment of the present application provides a fan fixing assembly fixed in a bottom case 50 of a medical device, including: a wind cavity bracket 10 and a fixing bracket 20. The wind cavity bracket 10 forms a wind passage 11, and a first fixing structure 13 is provided at an outlet end 12 thereof; the fixing bracket 20 includes a first connection structure 21 and a fixing plate 22. The first connection structure 21 is connected to the first fixing structure 13, and a fan bracket 30 is connected to a side of the fixing plate 22 facing the wind cavity bracket 10. By providing the wind cavity bracket 10 and the fixing bracket 20 to form an installation position for the fan bracket 30, and the fan is installed in the fan bracket 30, which is equivalent to directly fixing the fan on the bottom case 50, without affecting the disassembly and assembly of the rear cover plate. The fan can also directly align with the wind passage 11, achieving a directional cooling effect, and at the same time facilitating the arrangement of connection wires, which is beneficial for assembly.

[0036] It should be noted that when applying the technical solution of this embodiment, the disassembly and assembly of the rear cover plate can reduce the installation of fasteners caused by the fan arrangement, and only need to fix it. Therefore, the appearance of the rear cover plate can be ensured to be flat, which is beneficial for the appearance beautification of the medical device. At the same time, the connection wires can be adjusted from the original dynamic arrangement to a static arrangement, so that they will not move during the disassembly and assembly during maintenance, resulting in an obstacle to the troubleshooting of line faults, which helps to improve the maintenance efficiency.

[0037] Currently, on medical devices mainly made of sheet metal, small fans are generally placed on the rear cover plate of the medical device. Studs are riveted on the rear cover plate, and the fan is in hard contact with the studs. When the fan enables the high-frequency mode, the vibration frequency increases and collides with the studs, emitting harsh noises; when the maintenance personnel disassemble the rear cover plate, the fan will be disassembled together with the rear cover plate. At this time, the fan wires need to be disassembled to remove the rear cover plate; riveting studs on the rear cover plate can ensure a flat appearance, but the vibration frequencies of each fan are different, and the riveting studs have high requirements for perpendicularity to ensure less contact area between the fan and the studs, reducing manufacturability and being unable to reduce the decibel of the noise.

[0038] When applying the technical solution of this embodiment, the fan can select a corresponding blade structure according to different heat dissipation or ventilation requirements, and it can be located on the detachable fan bracket 30, with stronger adaptability and better interchangeability, and can adapt to different scenario requirements.

[0039] In a specific embodiment, the fixing plate 22 and the air cavity bracket 10 form the installation position of the fan bracket 30, that is, the fan bracket 30 is in clearance fit with the fixing plate 22 and the air cavity bracket 10 respectively. Such a setting has a compact structure and high assembly precision. At the same time, the fan bracket has a certain movement space and will not collide due to vibration, thus generating greater noise. The setting of the installation position can be used to adapt to the fan bracket 30 and can be used as a basis for judging whether the assembly of the fan bracket 30 or the fixing plate 22 and the air cavity bracket 10 is reliable in the production process, which is beneficial to improving the assembly efficiency.

[0040] Further, as Figures 5 to 7 shown, in some embodiments of the present application, the fixing bracket 20 is provided with a bearing platform 23, the bearing platform 23 is arranged at an angle with the fixing plate 22, and the bearing platform 23 can extend into the air passing channel 11. The setting of the bearing platform 23 plays a connecting role, so that the whole fixing bracket 20 is erected in the air passing channel 11, which can provide effective support for the fixing plate 22. At the same time, the combination degree with the air cavity bracket 10 is higher, and the connection strength is effectively improved, which is beneficial to improving the stability during the operation of the fan and achieving the purpose of reducing noise.

[0041] It should be noted that the fan bracket 30 and the bearing platform 23 are in clearance fit, that is, there is a gap between the two. Such a setting is beneficial to achieving electrical isolation and avoiding the phenomenon of electrical connection due to the electrical action between the bottom case 50 and the bearing platform 23. Further, the bearing platform 23 can be used to place the power element for rotating the fan. Such a setting has a more compact structure, effectively utilizes the space in the air passing channel 11, and at the same time, the generated fluid flow can cool the power element in the first time, and the heat dissipation effect is better.

[0042] In a specific embodiment, the bearing platform 23 is arranged at 90 degrees with the fixing plate 22, that is, the bearing platform 23 is perpendicular to the fixing plate 22. Such a setting can meet the specific setting of the fan orientation, has higher structural precision, and the special angle of 90 degrees is also convenient for manufacturing, improving the manufacturability.

[0043] As Figure 2 、 Figure 5 and Figure 6 shown, in some embodiments of the present application, the fixing bracket 20 includes a second connection structure 24 connected to the side of the bearing platform 23 away from the fixing plate 22, and the air cavity bracket 10 includes a second fixing structure 14 arranged in the air passing channel 11, and the second connection structure 24 is connected to the second fixing structure 14. The setting of the second connection structure 24 cooperates with the first connection structure 21 to completely fix the fixing bracket 20 and erect it in the air passing channel 11, which can provide stable structural stress for the fixing plate 22 and is not easy to generate deformation or assembly problems.

[0044] It can be understood that when components such as the fan bracket 30 and the fan are directly connected to the fixed plate 22, a certain gravitational influence will be generated. During assembly, the fixed plate 22 is prone to material deformation, resulting in assembly problems. When applying the technical solution of the above embodiment, the extension of the bearing platform 23 can be used to disperse the acting force concentrated on the fixed plate 22, offset the torque generated by the weight, and thus ensure the structural stability of the fixed plate 22.

[0045] As Figure 2 , Figure 4 and Figure 5 shown, in some embodiments of the present application, the air chamber bracket 10 includes two side walls 15 arranged in parallel. The second fixing structure 14 includes a connected cross beam 141 and two connecting arms 142. The two connecting arms 142 are respectively fixedly connected to the two side walls 15. The above-described second fixing structure 14 can connect the two side walls to form a mutual supporting effect, provide a stable structural force, and the cross beam can also be used as a connection point for the internal structure between the side walls 15.

[0046] It should be noted that the two connecting arms 142 extend in a direction parallel to the side wall 15 and away from the bearing platform 23. The two connecting arms 142 are respectively fixedly connected to the mounting holes 151 on the side wall 15 through fasteners. The mounting holes 151 are specifically countersunk holes. Such a setting makes the connection between the connecting arm 142 and the side wall 15 tight, reduces the possibility of loosening and crosstalk, and thus provides a more stable installation of the fixing bracket 20, which is beneficial to reducing the amplitude of vibration during fan operation and further reducing fan noise.

[0047] As Figure 4 and Figure 5 shown, in some embodiments of the present application, there are multiple second connecting structures 24, and the multiple second connecting structures 24 are respectively fixedly connected to the cross beam 141. Such a setting can form a tighter combination, provide a more stable structural connection relationship, make the state of the fan during operation more stable, and reduce fan noise.

[0048] It should be noted that, as Figure 2 and Figure 7 shown, in a specific embodiment, the second connecting structure 24 is two plate bodies extending vertically downward along the bearing platform 23. The plate bodies are arranged parallel to the cross beam 141. Two groups of corresponding through holes are provided on the plate bodies and the cross beam 141, and they are connected through threaded fasteners so that they are in contact with each other. Such a setting realizes tight connection at multiple positions, has a good fixing effect, is structurally compact, and is also convenient for installation in the narrow air passage 11. At the same time, the plate bodies arranged in this way and the first connecting structure 21 form extensions in two directions, and the bearing platform 23 is subjected to a certain extrusion effect through the structural force, thereby providing a vertically upward supporting stress, which is beneficial to bearing.

[0049] Further, a tongue 232 is provided between the two plate bodies of the second connection structure 24. The tongue 232 is an extension of the bearing platform 23. A mating slot is provided corresponding to the second fixing structure 14. The opening direction of the slot is vertically upward along the direction perpendicular to the bearing platform 23. During assembly, the tongue 232 enters and penetrates into the slot in a direction perpendicular to the cross beam 141, forming a degree-of-freedom restriction in the plane direction along the vertical cross beam 141. The plate body and the cross beam 141 form a degree-of-freedom restriction in the plane perpendicular to the cross beam 141, thereby completing the positioning. Then, the nut is passed through the two through holes and locked.

[0050] Such as Figure 3 and Figure 7 As shown, in some embodiments of the present application, the first fixing structure 13 extends inward along the outlet end 12, and the bearing platform 23 is provided with an avoidance space 231 corresponding to the first fixing structure 13. The setting of the avoidance space 231 is used to adapt to the first fixing structure 13 for convenient installation.

[0051] Specifically, the first fixing structure 13 is a connecting long arm extending outward along the direction of the air passage 11 on the side wall 15. The end of the connecting long arm extends inward relative to the outlet end 12. The length of the connecting long arm is adapted to the fan bracket 30. Such a setting is used to adapt to the installation space of the fan bracket 30, so that the fan bracket can be located between the fixing plate 22 and the outlet end 12 after being connected to the fixing plate 22. The first fixing structure 13 is an extension of the fixing plate 22, and its surface is parallel to the fixing plate. Such a structure is more compact and the connection is reliable. The avoidance space 231 can also correspond to the installation of the fastener.

[0052] In a specific embodiment, such as Figure 7 As shown, the fixing bracket 20 is a plate. After dividing the fixing plate 22, the bearing platform 23, the first connection structure 21 and the second connection structure 24 on it, first perform cutting operations to process the first connection structure 21 and the second connection structure 24, and at the same time process the assembly holes 221 and the fan through holes 222 on the fixing plate. Then perform bending. When bending the fixing plate 22, the fixing plate 22 drives the first connection structure 21, and the first connection structure 21 leaves the bearing platform 23 to form an avoidance space 231. After the second connection structure 24 is bent, a tongue 232 is formed. Such a setting has a compact structure and a convenient processing process.

[0053] Similarly, such as Figure 5 and Figure 8As shown, the second fixing structure 14 is a plate. After forming a slot and a perforation by subtractive machining, a cross beam 141 and two connecting arms 142 are formed by bending. The air cavity bracket 10 is integrally a plate. After forming a mounting hole 151, a connecting portion 16 on the side wall 15 and a through hole on the first fixing structure 13 by machining, it is bent to form the side wall 15. Then, the first fixing structure 13 is bent so that the end of the connecting long arm is bent and extends inward along the outlet end 12.

[0054] As Figures 1 to 6 shown, in some embodiments of the present application, a buffer structure 40 is provided between the fan bracket 30 and the fixing plate 22. The setting of the buffer structure 40 makes the fan bracket 30 and the fixing plate 22 form a soft contact. Such a setting can be used to absorb the kinetic energy generated during the operation of the fan, thereby reducing the vibration frequency of the fan and the decibel of the noise.

[0055] It should be noted that the fan bracket 30 and the fixing plate 22 are connected through the buffer structure 40, reducing the transmission path of the fan bracket 30. That is, the kinetic energy generated by the fan must be weakened by the buffer structure 40, and thus the influence on the fixing plate 22 is limited, effectively reducing the generation of noise.

[0056] Furthermore, in some embodiments of the present application, the buffer structure 40 is a silicone rivet. The silicone rivet is detachably connected to the fan bracket 30, and the silicone rivet abuts against the side of the fixing plate 22 away from the fan bracket 30. The material of the silicone rivet is silicone, which has good elastic ability and can fully absorb the vibration generated by the fan. Even under high-frequency vibration, it can effectively reduce the generation of noise. The rivet itself has excellent tensile strength and compressive strength, can withstand various external forces without being easily deformed or broken, has high installation accuracy, long service life, and meets the requirements of medical devices.

[0057] As Figures 1 to 9 shown, in some embodiments of the present application, the silicone rivet includes a head section 41, a buffer section 42, and a pagoda section 43 arranged in sequence. The head section 41 abuts against the side of the fixing plate 22 away from the fan bracket 30. The buffer section 42 abuts against the fixing plate 22 and the fan bracket 30 respectively. The pagoda section 43 cooperates with the fan bracket 30. The setting of the buffer section 42 is used to respectively abut against the assembly surfaces 31 of the fixing plate 22 and the fan bracket 30, playing a further buffering and connecting role, and the head section 41 plays a fixing and fastening role.

[0058] The pagoda section 43 is a structure formed by stacking multiple frustum shapes along the axial direction. A plurality of mounting holes 32 are provided on the assembly surface 31 of the fan bracket 30, and the diameter of the mounting holes is adapted to the smaller end of the frustum diameter. That is, through the tension of the rivets, the multiple frustums are respectively squeezed between the two assembly surfaces 31, so as to form a tight combination between the fan bracket 30 and the pagoda section 43. The setting of the silicone material can facilitate entry and detachment, so as to better realize the function of absorbing kinetic energy.

[0059] The fan bracket 30 is also provided with mounting holes 32 and a receiving cavity 33. The mounting holes are located around the fan bracket 30 and are adapted to the assembly holes 221 on the fixing plate 22, facilitating the passing through or threaded connection of the silicone rivets. The receiving cavity 33 is used for the installation of the fan and is adapted to the fan through hole 222. A transfer member or a through hole is provided inside it for connecting the output end of the power element.

[0060] It should be noted that the pagoda section 43 can be a structure with a pagoda shape. The smaller diameter section between the pagoda layers is adapted to the mounting holes 32, and the larger diameter section forms a clamping of the assembly surface 31. Such fixation is more reliable and will not fall off, and can fully absorb the kinetic energy generated by the fan vibration and reduce the generation of noise.

[0061] In some specific embodiments of the present application, a fan fixing assembly is provided, which can ensure the flatness of the appearance surface of the rear cover plate, and can eliminate the noise generated due to the high-frequency rotation requirement of the fan; at the same time, it can also make full use of the space volume, and subsequent disassembly and assembly are convenient, and it is possible to disassemble the rear cover plate without disassembling the fan wires.

[0062] To solve the technical problems, the present design provides a fan fixing assembly, which mainly includes: an air cavity bracket 10, a fixing bracket 20, a fan bracket 30 and a buffer structure 40. The fixing bracket 20 and the fan bracket 30 are connected through the buffer structure 40. After the fan is installed, the fixing bracket 20 and the air cavity bracket 10 are connected. The air cavity bracket 10 is fixedly connected to the bottom shell 50 of the device through threaded fasteners.

[0063] A riveted nut on the fixing bracket 20 is threadedly connected to the air cavity bracket 10. There are 4 assembly holes for assembling shock-absorbing silicone rivets (buffer structure 40), and one fan through hole 222 for the air outlet of the fan. The shock-absorbing silicone rivet has a multi-layer pagoda-shaped structure for adapting to various fan specifications. Among them, the air cavity bracket 10 is in a "C" shape, and the connecting part 16 at the bottom is connected to the bottom shell 50 through rivets.

[0064] The fan is connected to the fixed bracket 20 through damping silicone rivets and the fan bracket 30. The fan bracket 30 and the damping silicone rivets are in soft contact, which can reduce the decibel of the noise to a suitable value. At the same time, the fixed bracket 20 and the air cavity bracket 10 are linearly assembled and connected, which is convenient for later maintenance and repair. The air cavity bracket 10 is fixed to the main frame as a whole. When disassembling the rear cover plate, it is not necessary to disassemble the fan wires, ensuring a flat appearance, making the most of the internal space volume, and not requiring much operating space to be reserved.

[0065] In a second aspect, an embodiment of the present application provides a medical device, and the medical device includes the fan fixing assembly as described above. Among them, for the structure and function of the fan fixing assembly, reference can be made to the implementation manner of the fan fixing assembly in the above text, and details will not be repeated here.

[0066] The medical device can be an anesthesia machine, a veterinary anesthesia machine, etc., and can be realized through the above-mentioned fan fixing assembly, which can fully reduce the noise generated by the fan operation, and when disassembling and repairing the rear cover plate, it is not necessary to disassemble the fan wires, ensuring a flat appearance, making the most of the internal space volume, and not requiring much operating space to be reserved.
