Description

Technical Field

[0001] This application relates to the field of control enclosures, and more particularly to control enclosures and flow cytometers. Background Technology

[0002] Flow cytometers use optical detection modules to detect cell characteristics, including cell size, cell number, cell cycle, and cell phenotype analysis. Flow cytometers contain various optical and electrical components, resulting in complex overall circuitry.

[0003] The control enclosure is used to house the circuitry for controlling the flow cytometer. Modular design of the circuitry within the control enclosure facilitates installation. However, errors in the placement and sequence of multiple modules during installation can increase the difficulty of the process. Utility Model Content

[0004] To solve the above-mentioned technical problems, this application provides a control box and a flow cytometer. The control box of this application is easy to assemble.

[0005] This application is achieved through the following technical solution.

[0006] A first aspect of this application provides a control enclosure, comprising: an enclosure having a receiving space, the enclosure including a plurality of first limiting portions; and a plurality of circuit board assemblies, each circuit board assembly including a circuit board body and a mounting member, the circuit board body being mounted on the mounting member and located in the receiving space, the mounting member having at least one second limiting portion adapted to the first limiting portion to arrange and mount the plurality of circuit board assemblies in the enclosure, wherein the plurality of first limiting portions are arranged along a direction in which the plurality of circuit board assemblies are arranged, and along the direction in which the plurality of circuit board assemblies are arranged, the position of the second limiting portion of at least one of the plurality of circuit board assemblies is different from the position of the second limiting portion of the other circuit board assemblies.

[0007] The installation of the circuit board assembly can be limited by the adaptation of the first and second limiting parts. The second limiting part of at least one of the multiple circuit board assemblies is positioned differently from the second limiting parts of the other circuit board assemblies, thereby reducing the possibility of misalignment or misordering during the installation process. Specifically, because the second limiting part of one of the multiple circuit board assemblies is positioned differently from the second limiting parts of the other circuit board assemblies, the corresponding first limiting part is also positioned differently. Therefore, if this circuit board assembly is incorrectly installed on another circuit board, the installation will fail because it cannot adapt to the first limiting part at that position. This prevents the circuit board assembly from being incorrectly installed on the mounting position of another circuit board assembly.

[0008] In some embodiments of this application, along the direction in which the plurality of circuit board assemblies are arranged, the second limiting portions of at least two adjacent circuit board assemblies are not positioned the same; or along the direction in which the plurality of circuit board assemblies are arranged, the second limiting portion of each circuit board is positioned differently from the second limiting portions of the other circuit boards.

[0009] The second limiting part of two adjacent circuit board assemblies is positioned differently, which can prevent misalignment of the two adjacent circuit board assemblies during installation and can be applied to situations where the shapes and mechanisms of the two adjacent circuit board assemblies are the same or similar.

[0010] The second limiting portion of each of the multiple circuit board assemblies is positioned differently from the second limiting portions of the other circuit boards, which makes it easier and more accurate to install each circuit board assembly. This method is applicable to situations where each circuit board assembly has the same or similar shape and structure.

[0011] In some embodiments of this application, the mounting member further includes one or more third limiting portions, the third limiting portions and the second limiting portions being located at opposite ends of the mounting member; the housing further includes one or more fourth limiting portions, the fourth limiting portions being disposed opposite to the first limiting portions, and the third limiting portions being adapted to the fourth limiting portions to arrange and mount the plurality of circuit board assemblies in the housing.

[0012] By adapting the second and third limiting portions located at both ends of the mounting component to the first and fourth limiting portions, both ends of the mounting component can be foolproof, thereby improving the foolproof effect.

[0013] In some embodiments of this application, the first limiting part is a limiting post, and the second limiting part is a limiting groove.

[0014] In some embodiments of this application, the housing includes a plurality of guide mechanisms, each of the circuit board bodies being movably disposed on each of the guide mechanisms, the guide mechanisms extending along the insertion direction of the circuit board assembly.

[0015] The guide mechanism plays a guiding and limiting role in the installation and disassembly of the circuit board assembly. After the circuit board assembly is installed, the guide mechanism can also fix the main body of the circuit board.

[0016] In some embodiments of this application, the housing includes a first plate and a second plate disposed opposite to each other along a first direction. The first plate is provided with a first limiting portion at its end near the mounting member, and / or the second plate is provided with a first limiting portion at its end. The first direction, the insertion direction of the circuit board, and the arrangement direction of the plurality of circuit boards intersect each other. The plurality of guiding mechanisms include a plurality of first guiding mechanisms and a plurality of second guiding mechanisms. The plurality of first guiding mechanisms and the plurality of second guiding mechanisms are respectively located on the first plate and the second plate. The two ends of the circuit board body are respectively movably disposed on the first guiding mechanism and the second guiding mechanism. The opposite ends of the mounting member are respectively connected to the first plate and the second plate.

[0017] Both the first and second plates, which are positioned opposite each other, are equipped with guide mechanisms, which can guide and limit the assembly and disassembly of the circuit board assembly located between the first and second plates, and also serve to fix the main body of the circuit board after installation.

[0018] In some embodiments of this application, the housing includes a first plate, a second plate, and a third plate. The first plate and the second plate are disposed opposite to each other along a first direction, and the third plate is located between the first plate and the second plate. The first plate is provided with a ventilation opening. The control housing includes a heat dissipation mechanism and a support column. The support column is disposed on the side of the first plate away from the second plate to support the control housing. The heat dissipation mechanism is located on the second plate, and / or the heat dissipation mechanism is located on the third plate near the second plate. Air entering through the ventilation opening is discharged through the heat dissipation mechanism.

[0019] Because the heat dissipation mechanism is positioned opposite to the vent, the air entering from the vent of the first board flows out through the heat dissipation mechanism, allowing the air to flow through a larger space, thereby carrying away more heat from the main body of the circuit board in the space. The resulting ventilation path improves the heat dissipation efficiency.

[0020] In some embodiments of this application, the control box includes a track mechanism disposed between the support and the first plate, and the first plate is movable relative to the track mechanism.

[0021] This facilitates the installation and disassembly of the enclosure.

[0022] In some embodiments of this application, a filter element is provided inside the vent to filter the air entering the box through the vent.

[0023] The filter element can prevent foreign objects from entering the containment space and causing damage to the main body of the circuit board.

[0024] In some embodiments of this application, the third plate includes a closable door that can be opened to expose the circuit board body.

[0025] Opening the door exposes the main body of the circuit board, facilitating its repair and maintenance.

[0026] In some embodiments of this application, the mounting component includes a pull-out aid, the mounting component has a first side and a second side facing away from each other, the circuit board body is disposed on the first side, and a plurality of pull-out aids are provided, with the plurality of pull-out aids respectively located at opposite ends of the second side.

[0027] Pull-out aids help with the installation and removal of circuit board assemblies.

[0028] In some embodiments of this application, the control box includes a first handle assembly and a second handle assembly, the first handle assembly and the second handle assembly being located on both sides of the box, the first handle assembly including a first groove formed as a grip portion, and the second handle assembly including a second groove formed as a grip portion.

[0029] The handle assembly facilitates the movement of the control box.

[0030] A second aspect of this application provides a flow cytometer, comprising: an optical detection module; and a control housing as described in any one aspect of the first application, wherein the circuit board assembly in the control housing is signal-connected to the optical detection module.

[0031] The installation of the circuit board assembly can be limited by the adaptation of the first and second limiting parts. The second limiting part of at least one of the multiple circuit board assemblies is positioned differently from the second limiting parts of the other circuit board assemblies, thereby reducing misalignment and disorder during the installation of multiple circuit board assemblies and improving the production efficiency of the flow cytometer.

[0041] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0042] Flow cytometers use optical detection modules to detect cell characteristics, including cell size, cell number, cell cycle, and cell phenotype analysis. Flow cytometers contain various optical and electrical components, resulting in complex overall circuitry.

[0043] The control enclosure is used to house the circuitry for controlling the flow cytometer. Modular design of the circuitry within the control enclosure facilitates installation. However, errors in the placement and sequence of multiple modules during installation can increase the difficulty of the process.

[0044] To solve the above-mentioned technical problems, this application provides a control box and a flow cytometer. The control box of this application is easy to assemble.

[0045] The control box provided in this application includes: a box having a receiving space, the board including a plurality of first limiting portions; and a plurality of circuit board assemblies, each circuit board assembly including a circuit board body and a mounting member, the circuit board body being mounted on the mounting member and located in the receiving space, the mounting member having at least one second limiting portion, the second limiting portion being adapted to the first limiting portion to arrange and install the plurality of circuit board assemblies in the box, wherein the plurality of first limiting portions are arranged along the direction of the arrangement of the plurality of circuit board assemblies, and along the direction of the arrangement of the plurality of circuit board assemblies, the setting position of the second limiting portion of at least one of the plurality of circuit board assemblies is different from the setting position of the second limiting portion of the other circuit board assemblies.

[0046] In this application, the so-called different positions of the second limiting part means that, with the same coordinate system as reference, the second limiting part of one circuit board assembly is located on the first side of the mounting part of the circuit board assembly along the direction of the arrangement of multiple circuit boards, and the second limiting part of another circuit board assembly is located on the second side of the mounting part of the circuit board assembly along the direction of the arrangement of multiple circuit boards. Referring to the same coordinate system, the first side and the second side are different sides of the mounting part, so it can be considered that the positions of the second limiting parts of one circuit board assembly and the second limiting parts of another circuit board assembly are different.

[0047] The installation of the circuit board assembly can be limited by the adaptation of the first and second limiting parts. The second limiting parts of some circuit board assemblies are positioned differently from those of other circuit board assemblies, thereby reducing the possibility of misalignment or misordering during installation. Specifically, because the second limiting part of one circuit board assembly is positioned differently from the second limiting parts of other circuit board assemblies, the corresponding first limiting part is also positioned differently. Therefore, if this circuit board assembly is incorrectly installed on another circuit board, the installation will fail because it cannot adapt to the first limiting part at that position. This prevents some circuit board assemblies from being incorrectly installed in the mounting positions of other circuit board assemblies.

[0048] In this application, as Figures 1 to 6 As shown, the control enclosure 1 includes an enclosure 10 and multiple circuit board assemblies 20, and the enclosure 10 may form a receiving space. The circuit board assembly 20 may include a circuit board body 21 and a mounting member 22, and the circuit board body 21 is located within the receiving space.

[0049] In this application, the enclosure 10 may include a frame, which may be a sheet metal part, and the plate 100 may be disposed on the frame. The frame can be connected by connectors, which may include connecting blocks, connecting beams, etc. For example, the sheet metal frame of the plate box can be fixed together by connecting blocks and connecting beams to form the overall frame of the plate box.

[0050] In this application, the housing 10 may include multiple plates 100, which may be disposed on the frame. In this application, the guide mechanism, limiting part, etc., may be disposed on one or more of the frame, plates, connecting blocks, and connecting beams.

[0051] In this application, the shape of the housing 10 can be a cube, cuboid, or other regular or irregular shape. This application does not impose specific limitations; any structure capable of housing the circuit board assembly is within the scope required by this application. For ease of explanation, this application uses the following... Figure 1 The example shown is a box 10 that resembles a cuboid.

[0052] like Figures 1 to 6 As shown, the housing 10 may include a first plate 11 and a second plate 12 disposed opposite to each other along the first direction X. In the working state of the housing 10, the first plate 11 may be located below the second plate 12. It should be noted that the vertical position in this application is only a relative positional relationship.

[0053] like Figure 1As shown, the second plate 12 may also have a main body 121 and an extension 120, the extension 120 extending from the end of the main body 121 of the second plate toward the first plate 11 along the first direction X.

[0054] In this application, multiple circuit board assemblies 20 can be arranged along a second direction Y, which is the direction in which the multiple circuit board assemblies 20 are arranged. The circuit board assemblies 20 are inserted into the receiving space along a third direction Z, which is the insertion direction of the circuit board assembly 20.

[0055] In this application, the first direction X, the second direction Y, and the third direction Z can intersect each other. In some embodiments, the first direction X, the second direction Y, and the third direction Z can be approximately perpendicular to each other, but this application is not limited thereto, and the first direction X, the second direction Y, and the third direction Z can be intersected at any angle.

[0056] In some embodiments, the extension 120 may have a sub-plate extending in a third direction Z from one end near the first plate 11. This sub-plate may be located between the main body 121 of the second plate and the first plate 11 and disposed opposite to the first plate 11. In such embodiments, the second plate 12 may comprise the main body 121, the extension 120, and the sub-plate. In such embodiments, the main body 121, the extension 120, and the sub-plate may also form a space within which other components can be disposed. In this application, any one of the plurality of plates may be a single plate, or it may be composed of a main body, an extension, and a sub-plate, as in the embodiment of the second plate; this application does not impose limitations.

[0057] A third plate 13 may also be provided between the first plate 11 and the second plate 12.

[0058] In some embodiments, a fourth plate 14 may be provided between the first plate 11 and the second plate 12, and the fourth plate 14 may be disposed opposite to the third plate 13 along the second direction Y.

[0059] The circuit board body 21 is disposed on the mounting member 22. The extension direction of the circuit board body 21 is different from that of the mounting member 22, which facilitates the application of force through the mounting member 22 to install the circuit board body 21 into the receiving space. A circuit board motherboard can be disposed in the receiving space, and the circuit board body located inside the receiving space can be electrically connected to the circuit board motherboard.

[0060] In this application, the circuit board body 21 may extend along a third direction Z, and the mounting member 22 may extend along a second direction Y. In some embodiments, the circuit board body 21 may extend along a first direction X and a third direction Z, and the mounting member 22 may extend along the first direction X and the second direction Y.

[0061] like Figure 1 and Figure 2 As shown, the housing 10 may include a plurality of first limiting portions 110, and a mounting member 22 may have one or more second limiting portions 23. The shapes and structures of the first limiting portions 110 and the second limiting portions 23 are adapted to each other to arrange and mount the plurality of circuit board assemblies 20 in the housing 10. When the circuit board assemblies 20 are assembled in the housing 10, the first limiting portions 110 and the second limiting portions 23 contact or abut against each other to form a limiting position and fix the circuit board assemblies 20 to the housing 10.

[0062] Along the direction in which the multiple circuit board assemblies 20 are arranged, the second limiting portion 23 of some circuit board assemblies 20 is positioned differently from the second limiting portion 23 of other circuit board assemblies 20. This reduces the possibility of misalignment or misordering of the multiple circuit board assemblies 20 during installation. Specifically, since the second limiting portion 23 of some circuit board assemblies 20 is positioned differently from the second limiting portion 23 of other circuit board assemblies 20, the corresponding first limiting portion 110 is also positioned differently. Therefore, if some circuit board assemblies 20 are incorrectly installed on other circuit boards, the installation will fail because they cannot be matched with the first limiting portion 110 at that position. This avoids the possibility of incorrectly installing some circuit board assemblies 20 on the mounting positions of other circuit board assemblies 20.

[0063] In some embodiments of this application, along the direction in which the plurality of circuit board assemblies 20 are arranged, the second limiting portions 23 of at least two adjacent circuit board assemblies 20 are positioned differently. This difference in the positions of the second limiting portions 23 of adjacent circuit board assemblies 20 can prevent misalignment during installation and is applicable to situations where adjacent circuit board assemblies 20 have the same or similar shapes and mechanisms.

[0064] like Figure 2 As shown, along the second direction Y, the first circuit board assembly 221 and the second circuit board assembly 222 are arranged adjacent to each other. The second limiting part 23 of the mounting part of the first circuit board assembly 221 is located on the side of the mounting part away from the third plate 13, and the second limiting part 23 of the mounting part of the second circuit board assembly 222 is located on the side of the mounting part closer to the third plate 13. This arrangement means that the setting position of the second limiting part is different. Correspondingly, since the first limiting part 110 is adapted to the second limiting part 23, the setting position of the first limiting part is also different.

[0065] like Figure 2In the embodiment shown, during assembly, if the operator installs the first circuit board assembly 221 to the position where the second circuit board assembly 222 should be installed, since the second limiting part 23 of the first circuit board assembly 221 is located on the side away from the third board body 13, the second limiting part 23 of the first circuit board assembly 221 cannot be adapted to the first limiting part 110 at the installation position, and the first circuit board assembly 221 cannot be installed at the installation position, thus avoiding the installation error of the first circuit board assembly 221.

[0066] In some embodiments of this application, along the direction in which the plurality of circuit board assemblies 20 are arranged, the second limiting portion 23 of each circuit board in the plurality of circuit board assemblies 20 is positioned differently from the second limiting portion 23 of the other circuit boards.

[0067] The second limiting part 23 of each circuit board in the multiple circuit board assemblies 20 is positioned differently from the second limiting part 23 of the other circuit boards, which makes it easier and more accurate to install each circuit board assembly 20. This is applicable to situations where each circuit board assembly 20 has the same or similar shape and structure.

[0068] In this application, at least one mounting member 22 among the plurality of circuit board assemblies 20 may include a plurality of limiting portions. For example, the mounting member 22 may include a plurality of second limiting portions and one or more third limiting portions. The second limiting portion 23 and the third limiting portion may be located at opposite ends of the mounting member 22, respectively. Figure 2 As shown, the mounting parts of the third circuit board assembly 223 can be provided with a second limiting part 23 and a third limiting part at opposite ends along the first direction X.

[0069] In this application, the housing 10 may further include a fourth limiting part 112, which is disposed opposite to the first limiting part 110. The third limiting part and the fourth limiting part 112 can be adapted to each other to arrange and install multiple circuit board assemblies 20 in the housing 10. The first limiting part 110 and the fourth limiting part 112, which are disposed corresponding to the second limiting part 23 and the third limiting part, may be disposed on the first plate 11 and the second plate 12, respectively. In such an embodiment, a circuit board assembly with only the second limiting part cannot be mistakenly installed in the mounting position of the third circuit board assembly.

[0070] By adapting the second and third limiting portions located at both ends of the mounting member to the first and fourth limiting portions, both ends of the mounting member can be foolproof, thereby improving the foolproof effect. The mounting member 22 can be a sheet metal panel.

[0071] In some embodiments of this application, a first limiting part 110 is provided at the end of the first plate 11 near the mounting member. When the circuit board assembly 20 is installed in the housing 10, the first limiting part 110 can contact or abut against the second limiting part 23.

[0072] In some embodiments of this application, a fourth limiting part 112 is provided at the end of the second plate 12 near the mounting member. When the circuit board assembly 20 is installed in the housing 10, the fourth limiting part 112 can contact or abut against the third limiting part.

[0073] In some embodiments of this application, the first limiting part 110 is a limiting post, and the second limiting part 23 includes a limiting groove.

[0074] In some embodiments of this application, the fourth limiting part 112 is a limiting post, and the third limiting part includes a limiting groove.

[0075] like Figure 2 As shown, the third circuit board assembly 223 has a third limiting part formed by a limiting groove on the side near the second plate 12, and a second limiting part 23 formed by a limiting groove on the side near the first plate 11.

[0076] Since the limiting groove is formed by inward recessing at least one side of the mounting member 22, the production and manufacturing of the mounting member 22 can be simplified by forming the second limiting part 23 through such a limiting groove.

[0077] In some embodiments of this application, such as Figure 3 As shown, the housing 10 may include multiple guide mechanisms 130, and each circuit board body 21 is movably disposed on each guide mechanism 130. The multiple guide mechanisms 130 may correspond one-to-one with the multiple circuit board bodies 21. The guide mechanisms 130 extend along the insertion direction of the circuit board assembly.

[0078] The guide mechanism 130 plays a guiding and limiting role in the installation and disassembly of the circuit board assembly 20. After the circuit board assembly 20 is installed, the guide mechanism 130 can also fix the circuit board body 21.

[0079] In this application, the guide mechanism 130 can be a guide rail, such as a track or slide rail that can be provided on the board body 100. Correspondingly, the circuit board body 21 of the circuit board assembly 20 can have components such as pulleys and sliders to slide on the guide rail.

[0080] In this application, the guide mechanism 130 can be a groove or a protrusion, and correspondingly, the circuit board body 21 of the circuit board assembly 20 can have a protrusion or a groove to move along the aforementioned groove or protrusion.

[0081] It should be noted that this application does not limit the guiding mechanism to the structure described in the foregoing embodiments. The guiding mechanism of this application can be any structure that can guide the circuit board body 21 of the circuit board assembly 20.

[0082] like Figure 3 As shown, the multiple guiding mechanisms 130 may include multiple first guiding mechanisms 131 and multiple second guiding mechanisms 132. The multiple first guiding mechanisms 131 and multiple second guiding mechanisms 132 may be located on the first plate 11 and the second plate 12 respectively. The two ends of the circuit board body 21 are respectively movably disposed on the first guiding mechanism 131 and the second guiding mechanism 132. The opposite ends of the mounting member 22 are respectively connected to the first plate 11 and the second plate 12.

[0083] The first plate 11 and the second plate 12, which are arranged opposite to each other, are both provided with guide mechanisms 130, which can guide and limit the assembly and disassembly of the circuit board assembly 20 located between the first plate 11 and the second plate 12, and also serve to fix the circuit board body 21 after installation.

[0084] In some embodiments of this application, such as Figures 1 to 6 As shown, the third plate 13 is located between the first plate 11 and the second plate 12, and the first plate 11 is provided with a vent 111.

[0085] In some embodiments, a vent 111 is provided in the area of ​​the first plate 11 corresponding to the circuit board body 21.

[0086] In some embodiments of this application, the vent 111 may be equipped with a filter to filter the air entering the housing through the vent. In this application, the filter may be a type of filter cotton. The filter can prevent foreign objects from entering the containment space and causing damage to the circuit board body 21.

[0087] like Figure 1 As shown, the control box 1 includes a heat dissipation mechanism 15 and a support column 31. The support column 31 is disposed on the side of the first plate 11 opposite to the second plate 12 to support the control box 1.

[0088] The control box 1 may also include a track mechanism 32, which is disposed between the first plate 11 and the support column 31. The track mechanism 32 can be fixedly connected to the support column 31, and the first plate 11 can move relative to the track mechanism 32 to install the box 10 onto the track mechanism 32 or remove it from the track mechanism 32.

[0089] In this application, the heat dissipation mechanism 15 can be located on the second plate 12. Since the second plate 12 is arranged opposite to the first plate 11, the air entering from the vent 111 is discharged through the heat dissipation mechanism 15. A ventilation path is formed between the first plate 11 and the second plate 12. This ventilation path extends through the accommodating space, thereby removing heat from the multiple circuit board bodies 21 located in the accommodating space and improving heat dissipation efficiency.

[0090] In this application, as Figure 1 and Figure 2 As shown, the heat dissipation mechanism 15 can be disposed on the third plate 13. For example, the heat dissipation mechanism 15 can be located on the third plate 13 near the second plate 12, and air entering through the vent is discharged through the heat dissipation mechanism. The first plate 11 is located below the second plate 12, and the heat dissipation mechanism 15 is located on the third plate 13 near the second plate 12, that is, the heat dissipation mechanism 15 is located in the upper direction of the third plate 13. The heat dissipation mechanism 15 can be a cooling fan.

[0091] Air entering from the vent 111 of the first plate 11 rises after being heated by the circuit board body 21 of the circuit board assembly 20. Whether the heat dissipation mechanism 15 is located on the second plate 12 or at a higher position on the third plate 13, it is conducive to the exhaust of heated air, thereby improving heat dissipation efficiency.

[0092] Since the heat dissipation mechanism is positioned opposite to the vent, the air entering from the vent of the first board flows out through the heat dissipation mechanism, allowing the air to flow through a larger space of the containment space, thereby carrying away more heat from the main body of the circuit board 21 in the containment space. The resulting ventilation path improves the heat dissipation efficiency.

[0093] In some embodiments of this application, such as Figure 1 and Figure 5 As shown, the third plate 13 may include a closable door 16 that can be opened to expose the circuit board body 21.

[0094] Opening the door 16 exposes the circuit board body 21, facilitating the repair and maintenance of the circuit board body 21.

[0095] In some embodiments of this application, such as Figure 1 and Figure 4 As shown, the mounting component 22 may also include a puller 24. The mounting component 22 has a first side and a second side facing away from each other. The circuit board body 21 is disposed on the first side. Multiple pullers 24 may be provided, and the multiple pullers 24 may be located at opposite ends of the second side respectively.

[0096] The puller 24 is designed to facilitate the installation and removal of the circuit board assembly 20.

[0097] In some embodiments of this application, the control housing 10 further includes a first handle assembly 171 and a second handle assembly 172. The first handle assembly 171 and the second handle assembly 172 are respectively located on two opposing plates of a plurality of plates. The first handle assembly 171 includes a first groove 173 formed as a grip portion, and the second handle assembly 172 includes a second groove 174 formed as a grip portion. The handle assembly and grip portion facilitate the movement of the control housing 10. Operators or installers can easily movably mount the housing 10 to or remove it from the track mechanism 32 using the grip portion.

[0098] In some embodiments of this application, the sheet metal frame of the board box (box) is fixed together by connecting blocks and connecting beams to form the overall frame of the board box. The right side (third board) of the board box has an openable door (door) for easy maintenance of the circuit board assembly. The bottom of the board box (first board) is designed with dense perforations (vents) for air intake, and filter cotton is installed inside the air intake perforations to filter the air.

[0099] A cooling fan (heat dissipation mechanism) is designed on the upper right side of the chassis, allowing external air entering from the bottom of the chassis to flow over the internal circuit boards (circuit board bodies), carrying away heat and expelling it from the chassis through the upper cooling fan. The heat dissipation channel ensures airflow from bottom to top, following the principle of hot air rising, preventing excessive heat retention and accumulation. The chassis is designed with a handle assembly for easy movement. A rail (rail guide mechanism) is designed at the bottom of the chassis for fixing and removing the chassis. Support columns are designed under the rails to effectively separate the hydraulic and electrical components. The circuit board is equipped with a pull-out aid for simple and efficient insertion and removal of circuit board components. The sheet metal panel (mounting part) on the circuit board assembly is designed with a positioning notch (second limit part). The positioning notch works in conjunction with the error-proof positioning post (first limit part). Through different combinations of these two, the incorrect insertion and removal of circuit board components can be prevented, avoiding damage to the pins on the circuit board body caused by incorrect insertion. The circuit board assembly panel is designed with text and numbers for identification of each circuit board component.

[0100] Each circuit board assembly can be accurately inserted into the rear circuit board (main board) via the insertion rail (guide mechanism), thereby connecting each circuit board assembly to the rear circuit board and eliminating the need for connecting wires between circuit boards. Following the principle of hot air rising, the upward airflow channels dissipate heat from each circuit board; assembling each circuit board into an independent module within a housing allows for better modular application.

[0101] The enclosure of this application features a standardized design, a simple and regular structure, and is easy to process and install.

[0102] The enclosure design of this application features a specific airflow channel that can efficiently reduce the temperature of each circuit board, enabling the circuit boards to operate safely and stably.

[0103] This application features a unique combined error-proof structure that uses different positioning gaps and error-proof positioning posts to prevent incorrect insertion of multiple circuit boards, thus avoiding damage to the circuit boards.

[0104] The plate box design of this application, including the track and support columns, allows for easy removal of the plate box and achieves liquid-electric separation.

[0105] This application uses a pull-out aid and a plug-in rail, which enables simple and efficient installation of circuit boards.

[0106] This application is designed with a movable door for circuit board maintenance.

[0107] The text printed on the circuit board assembly of this application can effectively identify each circuit board assembly.

[0108] Based on the same or similar concept, this application also provides a flow cytometer, including: an optical detection module; a control box as described in any of the foregoing embodiments, wherein a circuit board assembly 20 in the control box is signal-connected to the optical detection module.

[0109] The installation of the circuit board assembly 20 can be limited by the adaptation of the first limiting part 110 and the second limiting part 23. The setting position of the second limiting part 23 of at least one of the multiple circuit board assemblies 20 is different from that of the second limiting parts 23 of the other circuit board assemblies 20, thereby reducing the misalignment and disorder of the multiple circuit board assemblies 20 during the installation process and improving the production efficiency of the flow cytometer.
