Description

Technical Field

[0001] This utility model belongs to the field of fume hood technology, and more specifically, relates to an integrated laboratory fume hood. Background Technology

[0002] Laboratory fume hoods are irreplaceable core safety equipment in chemical, biological, pharmaceutical, and materials laboratories. Their basic mission is to create a continuous and controllable negative pressure airflow in the experimental area, promptly capturing and expelling harmful vapors, aerosols, or dust emitted during reactions, thereby protecting the breathing zone of laboratory personnel and maintaining a clean indoor environment. Since their introduction in the early 20th century, the form of fume hoods has evolved from simple smoke hoods to all-steel explosion-proof structures, and their function has expanded from simple exhaust to a basic safety unit integrating lighting, window isolation, and emergency exhaust. With the accelerated pace of modern experiments, the diversification of experimental projects, and the improvement of laboratory appearance standards, researchers have placed higher expectations on fume hoods, demanding both safety and efficiency as well as neatness and aesthetics. As a result, various integrated solutions have emerged: some have directly attached sockets and valves to the outer wall of the side panel, some have stacked storage drawers in the under-work space, and some have attempted to install fixed displays on the top for electronic work guidance. However, most of these "integrations" remain at the level of functional assembly, with each subsystem installed independently and protruding outwards, resulting in numerous sharp edges, gaps, and exposed pipes on the cabinet surface. During routine cleaning, personnel must avoid these protruding objects, as disinfectant cloths cannot wipe the entire surface in one go. Acid and alkaline fumes easily condense and crystallize in crevices, corroding threads and wire insulation over time. More importantly, traditional integrated solutions do not consider human-machine interaction. Information displays are often fixed to the top or side, resulting in a harsh viewing angle. Operators need to frequently look up or turn around, forcing their attention to switch back and forth between experimental actions inside the fume hood and the external display interface, increasing the probability of misoperation. Furthermore, while external storage modules increase volume, they sacrifice effective tabletop depth. Deep containers can only be retrieved by blindly reaching into the cabinet, with the head subsequently entering the contaminated area, thus undermining the original purpose of exhaust ventilation protection. Utility Model Content

[0003] In view of this, the present invention provides an integrated laboratory fume hood that solves the problem of traditional fume hoods being unable to achieve a truly flat and integrated design due to the protruding external modules causing cleaning dead corners and airflow disturbances.

[0004] This utility model is implemented as follows: This utility model provides an integrated laboratory fume hood, comprising: Cabinet; A viewing window, which is liftably mounted on the front of the cabinet; The work surface is located inside the cabinet and below the viewing window; An exhaust duct is provided at the top of the cabinet and communicates with the interior of the cabinet. Lighting strip, which is installed on the inner top wall of the cabinet and extends laterally; A face recognition panel is embedded in one side wall of the cabinet and flush with the side wall of the cabinet. The display screen mechanism, located at the top front edge of the cabinet, consists of three independently functioning screens; A high-depth pull-out basket, which is slidably mounted on one side wall of the cabinet exterior; A concealed countertop, which is horizontally slidable within the rear wall of the cabinet and located below the work surface; The function panel is embedded inside the cabinet and located below the work surface. The function panel is equipped with a flip cover.

[0005] The technical advantages of the integrated laboratory fume hood provided by this utility model are as follows: By integrating the face recognition panel, retractable display screen, status display screen, log display screen, high-depth pull-out basket, hidden tabletop, and functional panel with flip-top cover into the various walls of the cabinet in an "embedded + flush" manner, the fume hood retains the traditional exhaust, lighting, and viewing window functions while having no protruding parts on the overall outer surface. This avoids the risk of collisions for laboratory personnel and eliminates cleaning dead corners caused by exposed pipelines, thereby improving space utilization and overall appearance. Furthermore, the positions of each module are distributed from top to bottom and from front to back according to the operation flow, allowing laboratory personnel to complete the entire set of actions such as identity recognition, parameter viewing, equipment retrieval and placement, tabletop expansion, and gas and electricity connection while standing, without the need for additional movement, significantly shortening the experimental preparation time.

[0006] Based on the above technical solution, the integrated laboratory fume hood of this utility model can be further improved as follows: The viewing window is an explosion-proof glass viewing window, and the two sides of the viewing window are connected to the cabinet via vertical sliding rails.

[0007] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the explosion-proof glass window is raised and lowered by the vertical sliding rail. In the event of a sudden explosion, the glass fragments are restrained by the side of the sliding rail and will not fly into the operating area. Moreover, the sliding rail is hidden in the interlayer of the cabinet side wall, with only a narrow gap left on the outside. This ensures smooth lifting and lowering and avoids the problems of dust accumulation and corrosion of traditional external guide rails, keeping the inner wall of the cabinet smooth and easy to clean.

[0008] Furthermore, the work surface is an acid and alkali resistant surface, and the perimeter of the work surface is provided with an anti-overflow edge.

[0009] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the anti-overflow edge of the acid and alkali resistant tabletop, which is integrally molded around the perimeter, can form a temporary dike when reagents are accidentally spilled, preventing liquid from seeping into the exhaust channel or electrical cavity along the gaps in the cabinet, reducing the risk of cross-contamination and corrosion. At the same time, the anti-overflow edge is made of the same material and thickness as the tabletop, and visually presents a continuous ring, which does not affect the horizontal sliding of the utensils.

[0010] Furthermore, the lighting strip is an LED light strip, and the outer cover of the lighting strip is equipped with a transparent protective cover.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the LED light strip is completely wrapped by a transparent protective cover, which is connected to the top wall of the cabinet by a snap and can be disassembled by hand. This not only prevents corrosive gases from damaging the LED beads, but also allows for quick replacement of the light strip without turning off the main power supply, achieving "zero-tool" maintenance and ensuring long-term stable lighting.

[0012] Furthermore, the display screen mechanism includes: A telescopic display screen, which can be raised and lowered and is installed on the top wall inside the cabinet and located in front of the lighting strip; A status display screen is fixedly installed on the top wall inside the cabinet and located on one side of the telescopic display screen; A log display screen is fixedly installed on the top wall inside the cabinet and located on the other side of the telescopic display screen; The surfaces of the status display screen and log display screen are flush with the top wall of the cabinet.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the status display screen and the log display screen are embedded in the same horizontal plane of the top wall in an ultra-thin form. The three screens are arranged in a "concave" shape. When the middle telescopic screen is lowered, it fills the visual gap and forms a continuous information display band. This ensures that key parameters are always on and visible, while avoiding the feeling of oppression in the head space caused by multiple large screens.

[0014] Furthermore, the telescopic display screen is connected to the top wall of the cabinet via a vertical sliding rail mechanism, and the telescopic display screen can be stored inside the top wall of the cabinet.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the telescopic display screen is raised and lowered by a vertical sliding rail mechanism hidden in the top wall interlayer. After the screen is fully retracted, its lower surface is flush with the decorative panel on the top wall of the cabinet, which does not occupy the net height inside the cabinet and will not form a dust accumulation platform. When it is necessary to view the SOP or remote guidance, the screen can be lowered to the front of the eye, so that the experimenter can operate without turning his head, reducing neck fatigue.

[0016] Furthermore, the face recognition panel is covered with scratch-resistant tempered glass, and has a built-in camera and RFID reader.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the face recognition panel is covered with scratch-resistant tempered glass, the camera and RFID card reader are integrated on the same surface, and the experimenter can complete the card swiping or face swiping even when wearing gloves. The recognition window extends on the same curved surface as the side wall of the cabinet without any extra protrusions, avoiding the defects of traditional external reading heads that are easily damaged by collisions and liquid splashes.

[0018] Furthermore, the high-depth pull-out basket is connected to the side wall of the cabinet via heavy-duty silent slide rails, and the basket is made of stainless steel.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the deep pull-out basket can be completely pulled out of the cabinet with the help of heavy-duty silent slide rails. The depth of the pull-out basket is equivalent to the depth of the cabinet. Even the innermost utensils can be taken and placed horizontally without having to reach into the depth of the cabinet, reducing the time spent with the head in the ventilation area. The stainless steel basket and slide rails are electrolytically polished, with low surface roughness. After acid and alkali adhering, they can be directly rinsed, shortening the cleaning time.

[0020] Furthermore, the concealed countertop is connected to the rear wall of the cabinet via concealed sliding rails, and the countertop is made of phenolic resin board or ceramic board.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the hidden countertop is retracted into the groove of the back wall through the hidden slide rail. The groove opening is the same thickness as the countertop. After being pushed in, the back side is flush with the inner wall of the cabinet, so the airflow will not form local vortices. When the back countertop is pulled out, the height is the same as the main countertop, which can temporarily place portable instruments and expand the operating area without affecting the closing of the window, realizing a quick switch of "visible when in use and hidden when not in use".

[0022] Furthermore, the functional panel is a flip-up panel, with a gas valve, power socket and network interface on the inner wall of the panel, and the panel is flush with the inner wall of the cabinet when closed.

[0023] The functional panel is connected to the cabinet side wall via a concealed hinge mechanism. The hinge axis is horizontally set along the lower edge of the panel, allowing the panel to be flipped down and opened, and then held horizontally. A reinforcing rib is embedded in the inner side wall of the panel. Gas valves, power sockets, and network interfaces are all embedded in the reinforcing rib and face the inner cavity of the cabinet. The pipelines connected to the rear of each interface extend upward along the longitudinal wiring grooves pre-drilled in the inner side wall of the cabinet and converge at the top main interface. An elastic sealing strip is provided on the outer periphery of the panel. When the panel is closed, the sealing strip is pressed against the periphery of the opening in the cabinet side wall to form a flat and continuous surface. The outer side wall of the panel shares the same decorative layer with the cabinet side wall, so that the panel is visually seamless and tactilely smooth when closed, achieving complete flushness with the inner wall of the cabinet.

[0024] Compared with existing technologies, the beneficial effects of the integrated laboratory fume hood provided by this utility model are as follows: While retaining the basic ventilation and isolation functions of a fume hood, this utility model transforms all needs for human-computer interaction, item storage, and gas / electricity access into a "hidden embedded" design: the identification area is coplanar with the side wall, the display area with the top wall, the storage area with the inner wall, and the gas / electricity area with the structural column. All functional modules do not extend beyond the cabinet's outline, thus achieving a holistic visual experience of "no visible exterior, but a wealth of internal features" for the first time in the fume hood field. Because the outer surface is continuously flat, daily disinfection can be completed in one go, eliminating cleaning blind spots caused by traditional protruding nodes, significantly reducing the risk of chemical residue accumulation and microbial growth. At the same time, the smooth outline eliminates bumps and knocks when people walk around, and also avoids leaks or power outages caused by pipes being snagged by clothing. In terms of information presentation, the three screens on the top wall are arranged in a concave, wraparound layout. The retractable screen can be lowered to directly in front of the operator, with a minimal angle to the main line of sight. This allows researchers to read key parameters without looking up or turning to the side, keeping their attention focused on the hands-on operating area, creating a "coaxial" state of concentration. This effectively reduces problems such as sample addition errors and scale misreading caused by shifting gaze. The high-depth pull-out basket and the concealed work surface utilize the same sliding rail concept. When pulled out, it is flush with the main work surface, seamlessly connecting the expanded space with the original operating area. Instruments can be pushed and pulled smoothly, avoiding the vibration caused by height differences that can lead to drift in precision balance readings when using traditional folding panels. When retracted, it blends seamlessly with the cabinet wall, without disrupting the internal airflow organization, ensuring uniform surface airflow. The flip-up pneumatic and electrical panel concentrates valves, sockets, and network ports on one side. Flipping it down to a horizontal position allows for easy plugging and unplugging. When closed, it maintains a complete decorative surface with the side wall, preventing dust from falling into the interfaces and eliminating the risk of water damage to traditional external sockets during cleaning. Overall, this utility model, through the integrated thinking of "structure as function," transforms safety, efficiency, and aesthetics from contradictory design goals into a mutually reinforcing symbiotic relationship: the simpler the appearance, the more thorough the cleaning; the more focused the operation, the lower the error; the more concealed the modules, the more stable the airflow, thus providing laboratories with a truly future-oriented, sustainable fume hood solution that takes into account both people and the environment.

[0030] Furthermore, in the above technical solution, the work surface 30 is an acid and alkali resistant work surface, and the perimeter of the work surface 30 is provided with an anti-overflow edge.

[0031] Furthermore, in the above technical solution, the lighting strip is an LED strip, and the outer cover of the lighting strip is equipped with a transparent protective cover.

[0032] Furthermore, in the above technical solution, the display screen mechanism 11 includes: The telescopic display screen is installed on the top wall inside the cabinet 10 and is located in front of the lighting strip; The status display screen is fixedly installed on the top wall inside the cabinet 10 and located on the horizontal side of the telescopic display screen. The log display screen is fixedly installed on the top wall inside the cabinet 10 and located on the other side of the telescopic display screen.

[0033] Furthermore, in the above technical solution, the telescopic display screen is connected to the top wall of the cabinet 10 via a vertical sliding rail mechanism, and the telescopic display screen can be stored inside the top wall of the cabinet 10.

[0034] Furthermore, in the above technical solution, the surface of the face recognition panel 40 is covered with scratch-resistant tempered glass, and the face recognition panel 40 has a built-in camera and RFID card reader.

[0038] First embodiment: The cabinet adopts an all-steel floor-standing structure. The side and top walls are punched out in one piece during the sheet metal stage, creating recessed windows. A rectangular cavity is reserved on the left side wall for embedding the facial recognition panel. Three parallel slits are punched out at the front edge of the top wall to house the telescopic display screen, status display screen, and log display screen, respectively. All screens use ultra-thin industrial-grade LCD screens of the same thickness. The back of the screen is fixed to an aluminum profile beam that runs through the width of the cabinet with countersunk screws. The two ends of the beam are then welded to the side wall frame to form an "invisible keel" structure, making the screen surface flush with the top wall decorative panel. The deep pull-out basket uses 304 stainless steel wire baskets. The depth of the basket is consistent with the depth of the cabinet cavity. The two sides are connected to the side wall columns by hidden heavy-duty slide rails. The slide rails are completely hidden between the insulation layer and the decorative panel. When the experimenter pulls it out, the basket can extend out of the cabinet as a whole, and the deepest container can be retrieved horizontally, avoiding the need for arms to reach into the contaminated area. The concealed worktop is made of 20mm thick epoxy resin board, with two T-shaped grooves machined on the back. Hidden slide rails are embedded in these grooves, and the slide rail bases are locked to the rear wall frame. When normally in use, the worktop is pushed into the rear wall recess, with its front end flush with the rear wall decorative panel. When pulled out, it is level with the main worktop, allowing for temporary placement of portable balances or small reactors. The pneumatic and electrical function panel is located on the right side wall. The lower edge of the panel is connected to the reinforcing frame via a concealed hinge. The inner wall of the panel is pre-installed with gas valves, waterproof sockets, and RJ45 modules. Rear piping runs along the pre-laid pipes inside the side wall to the top. When the panel is closed, the outer surface and the side wall coating are the same color and texture, providing a seamless tactile experience. This embodiment is suitable for university teaching laboratories where experiments primarily involve conventional organic synthesis, with high operation frequency and personnel movement. The smooth outer surface allows for one-time disinfection and wiping, reducing cleaning time during breaks. Furthermore, the absence of protruding edges reduces the risk of bumps and falls for students, ensuring teaching safety.

[0039] Second embodiment: The cabinet adopts a steel-wood composite structure, with steel side walls covered by corrosion-resistant chemical-resistant board; the top wall uses honeycomb aluminum panels of the same color, reducing weight while ensuring strength. A rectangular cavity is reserved on the left side wall to install a face recognition panel. The outer surface of the panel is covered with tempered glass with the same texture as the chemical-resistant board, visually forming a continuous texture with the side wall; three parallel slits are also opened at the front edge of the top wall to accommodate three screens respectively. The back of the screens shares a through-type aluminum profile beam, and the two ends of the beam are locked to the side wall frame, making the screen surface flush with the honeycomb panel of the top wall. The high-depth pull-out basket uses 316 stainless steel wire basket, and the depth of the basket is slightly less than the depth of the cabinet cavity. The two sides are connected to the side wall frame by hidden heavy-duty slide rails; the slide rails are completely hidden between the insulation layer and the chemical-resistant board, and the basket can be extended out of the cabinet as a whole when pulled out, making it easy to retrieve large-capacity solvent bottles. The concealed worktop uses 20mm thick phenolic resin board with two T-shaped grooves machined on the back, into which concealed slide rails are embedded. The slide rail bases are locked to the rear wall frame. When the worktop is pushed into the rear wall groove, its front end is coplanar with the phenolic resin board. When pulled out, it is at the same height as the main worktop, allowing for the placement of a precision balance or a small reactor. The pneumatic and electrical control panel is located on the left side wall. The lower edge of the panel is connected to the reinforcing frame via a concealed hinge. The inner wall of the panel is pre-fabricated with gas valves, waterproof sockets, and a USB-C module. The rear pipelines run along the pre-laid pipes inside the side wall to converge at the top. When the panel is closed, the outer surface is the same color and texture as the phenolic resin board, achieving an "invisible" effect. This embodiment is suitable for enterprise R&D laboratories, where experimental projects mainly involve small-scale amplification or process verification, requiring high cleanliness and appearance consistency. The flat, non-protruding cabinet surface meets the cleanroom wall workshop's review requirements for "easy cleaning and no sanitary dead corners." At the same time, the concealed pneumatic and electrical control panel avoids external sockets being sprayed with water during cleaning, extending interface life and reducing maintenance costs during verification.

[0040] Specifically, the principle of this utility model is as follows: This utility model follows the overall principle of "negative pressure protection as a prerequisite, structural integration as a means, and optimized flow as a goal." After the fume hood is started, the top exhaust duct establishes a stable negative pressure in the cabinet cavity, and the front window forms an air inlet. The airflow carries pollutants into the exhaust system along a preset path, and this basic physical process remains unchanged. On this basis, this utility model decomposes the additional functions into three categories of needs: "information, storage, and gas and electricity," and maps them to the three structural spaces of the cabinet: "top layer, lower layer, and side columns," which were originally underutilized. This allows the function and structure to share the same geometric surface, thereby avoiding any protrusion. The top layer area, being far from the main pollution path and located in front of the operator's natural line of sight, is selected as the information display area: the fixed status screen and log screen are embedded in the top wall in an ultra-thin form, sharing the supporting keel with the inner lining plate; the telescopic screen is hidden in the top wall interlayer through a synchronous belt-slide rail mechanism, and can be vertically raised and lowered under the drive of a motor. The signal and power are followed by a spiral drag chain to ensure that repeated movements do not break the line. The lower area, close to the ground and with minimal impact on airflow, was chosen as the storage area: The tall, deep pull-out baskets are fixed to the side wall frame using heavy-duty concealed rails, completely hidden between the cabinet's insulation layer and decorative panels. When the baskets are pulled out, the load is directly transferred to the base via the side wall columns, without increasing the load on the countertop. The basket depth is equal to the cabinet depth, allowing even the deepest containers to be accessed horizontally, preventing arms from reaching into contaminated areas. The side column area, due to its sufficient structural thickness, was chosen as the gas and electrical service area: Rectangular grooves are pre-fabricated on the inner wall of the side panels, with reinforcing frames welded around the groove openings. The flip-up panel is fixed to the lower frame edge via concealed hinges. Gas valve seats, power sockets, and network modules are pre-punched and riveted to the inner wall of the panel. All rear pipelines run along pre-laid pipes inside the side panels to the top for convergence. When the panel is closed, the sealing strip and reinforcing frame are pressed together, forming a flat, continuous wall surface that both isolates corrosive gases and withstands the impact of cleaning water guns. Through the above-mentioned "space borrowing" strategy, each functional module achieves "zero footprint" physically, "zero protrusion" visually, and "zero disturbance" in terms of airflow. Thus, without changing the original safety principle of the fume hood, human-computer interaction, material management, and energy access are transformed into part of the structure itself, enabling safety, efficiency, and aesthetics to be improved simultaneously.
