Abstract
Description
Technical Field
[0001] This utility model relates to the field of laboratory animal husbandry equipment, and in particular to a multi-fan main unit cabinet. Background Technology
[0002] In the practical application of IVC (Individual Ventilated Cages) housing, the main unit, as a core component, generates noise that significantly impacts the experimental environment. Existing IVC housing main units contain components such as fans that produce noise during operation. Since laboratory mice are extremely sensitive to sound, this noise directly interferes with their living environment. Continuous noise stimulation can easily induce stress responses in mice, altering their normal physiological indicators and causing research results based on these mice to deviate from reality. This reduces the accuracy and reliability of experimental data, adversely affecting scientific research. Therefore, noise reduction measures for the main unit's operation urgently need optimization.

[0033] This utility model's multi-fan main unit cabinet is a new type of equipment that integrates high-efficiency sound insulation, convenient operation, and flexible interaction. It is applied in the field of laboratory animal breeding equipment, playing a role in creating a quiet and stable breeding environment for laboratory animals, improving the convenience of equipment operation and maintenance, and ensuring the accuracy of scientific research experimental data.
[0034] Specific references Figures 1-2As a specific embodiment of the multi-fan main unit cabinet of this utility model, the multi-fan main unit cabinet includes: a body 110, a cabinet door 120, a sound insulation panel, and a partition 140. The body 110 serves as the basic load-bearing structure, providing sufficient installation space and accommodating ductwork penetration, thus building a stable framework for equipment operation. The cabinet door 120 can enclose the body 110, ensuring the airtightness of the internal environment and facilitating equipment maintenance. The sound insulation panel effectively blocks noise generated during equipment operation, reducing interference with the external experimental environment. The partition 140 divides the interior of the body 110 into different chambers, achieving separate placement of the exhaust and intake chambers and avoiding airflow interference. These four core components work together to provide a suitable placement environment for the multi-fan main unit from multiple aspects such as space utilization, noise control, and ease of operation, ensuring the stable operation of the equipment.
[0035] The unit body 110 is a hollow structure with an open front end. The return air duct 150 and exhaust air duct 160 of the multi-fan main unit can pass through the top of the unit body 110, and the supply air duct 170 of the multi-fan main unit can pass through both sides of the unit body 110. The hollow structure with an open front end provides ample space for the multi-fan main unit. The open front end facilitates the installation, inspection, and maintenance of the main unit and its internal components. The fact that the return air duct 150 and exhaust air duct 160 of the multi-fan main unit can pass through the top of the unit body 110, and the supply air duct 170 can pass through both sides of the unit body 110, is a reasonable layout based on the characteristics and functions of the air ducts. The return air duct 150 adopts a Y-shaped design. This shape allows a main pipe to branch into two branch pipes, which can simultaneously connect two different rat cages or experimental areas, enabling simultaneous recovery of exhaust gas from multiple areas and improving exhaust gas collection efficiency. The through hole at the top of the unit 110 is compatible with the main pipe of the Y-shaped return air duct 150, ensuring the stability and sealing of the return air duct 150 after installation. This allows the recovered exhaust gas to smoothly enter the main unit for treatment through the return air duct 150 and then be discharged through the exhaust duct 160. The supply air duct 170 is an inverted Y-shape, meaning that a main pipe extends from both sides of the unit 110 and branches into two branch pipes. This allows the treated clean air to be delivered to two different rat cages or experimental areas simultaneously, achieving uniform air supply and ensuring consistent air quality in each area. The through holes on both sides of the unit 110 match the main pipe of the inverted Y-shaped supply air duct 170, which not only facilitates the installation and fixation of the supply air duct 170 but also allows the delivered clean air to be more rationally distributed in the experimental space, meeting the air supply needs of multiple experimental areas. This design of the 110 unit, combined with the ductwork, fully utilizes the diversion advantages of Y-shaped and inverted Y-shaped ductwork. The layout of the through holes on the top and sides of the 110 unit makes exhaust gas recovery and clean air delivery more efficient and precise, providing strong support for air circulation and air pressure control in the experimental environment.
[0036] Furthermore, such as Figure 1 As shown, the unit 110 has a hollow, vertical rectangular shape, with an opening at the front providing operating space for equipment installation and debugging. The pre-drilled through-hole at the top accommodates the return air duct 150 and exhaust air duct 160 of the multi-fan main unit, allowing the ducts to connect naturally to the internal components of the main unit. The through-hole design on both sides of the bottom of the unit 110 provides an installation channel for the supply air duct 170. This layout conforms to the airflow path of the multi-fan main unit: the return air duct 150 introduces waste gas, the exhaust air duct 160 discharges purified gas, and the supply air duct 170 delivers clean air. Through the spatial adaptation of the unit 110, smooth airflow circulation of "waste gas recovery - purification treatment - fresh air delivery" is ensured, contributing to the control of air quality and pressure in the experimental environment.
[0037] The cabinet door 120 has a rectangular structure and is located at the front of the unit body 110. Its shape matches the front opening of the unit body 110, effectively sealing off the internal space. This design serves two purposes: firstly, it prevents external dust and debris from entering the unit body 110, protecting the multi-fan main unit and reducing interference from external factors; secondly, the enclosed space, combined with sound insulation panels, enhances overall sound insulation, reducing the transmission of operating noise and ensuring a quiet experimental environment.
[0038] Furthermore, such as Figure 1 As shown, the rectangular cabinet door 120 precisely matches the front opening of the unit 110, completely covering the opening when closed to form a physical barrier. On one hand, it prevents external dust and debris from entering the unit 110, protecting the internal multi-fan main unit; on the other hand, it works in conjunction with sound insulation panels to enhance noise reduction and minimize noise leakage during unit operation. When open, it provides a wide operating surface for maintenance personnel, facilitating inspection and component replacement, balancing equipment protection with ease of operation, and adapting to the needs of experimental scenarios.
[0039] The sound insulation panels are made of polyester fiber sound-absorbing panels, which are installed on the outer wall of the unit 110 and the cabinet door 120. Polyester fiber sound-absorbing panels have excellent sound absorption and insulation properties, effectively absorbing and blocking sound transmission. Installing these panels on both the outer wall of the unit 110 and the cabinet door 120 creates double sound insulation protection. The sound insulation panels on the outer wall of the unit 110 prevent noise from spreading outwards from the sides of the unit 110, while the sound insulation panels on the cabinet door 120 specifically reduce noise leakage from the front opening of the unit 110. Together, these two types of panels significantly reduce the noise generated by the multi-fan main unit during operation, creating a quiet growth environment for laboratory animals.
[0040] Furthermore, such as Figure 1As shown, the sound insulation panel, made of polyester fiber sound-absorbing material, is attached to the outer wall of the unit 110 and the surface of the cabinet door 120 using adhesives, clips, or other methods. The sound insulation panel on the outer wall of the unit 110 encloses the operating area of the main unit, absorbing and blocking noise from spreading in all directions; the sound insulation panel on the cabinet door 120 blocks the noise leakage path from the front opening, creating a synergistic effect of the dual sound insulation structure. Utilizing the sound-absorbing properties of the polyester fiber sound-absorbing panel, the noise from the multi-fan main unit is significantly reduced, creating a quiet breeding environment for experimental animals and preventing noise interference with experimental data.
[0041] The partition 140 is a plate-like structure located inside the unit body 110, dividing the interior of the unit body 110 into a first chamber and a second chamber. The first chamber is used to house the exhaust chamber of the multi-fan main unit, and the second chamber is used to house the air inlet chamber of the multi-fan main unit. The partition 140, with its plate-like structure, is a scientifically designed spatial layout. The first chamber is specifically for the exhaust chamber of the multi-fan main unit, and the second chamber is for the air inlet chamber, thus separating the two components with different functions: exhaust and air intake. This partitioning not only prevents the exhaust gas from the exhaust chamber from interfering with the fresh air drawn in by the air inlet chamber, ensuring the cleanliness of the intake air and the efficiency of the exhaust, but also makes the internal layout of the unit body 110 more organized, facilitating individual maintenance and management of different components, and improving the usability and functionality of the main unit cabinet.
[0042] Furthermore, such as Figure 1 As shown, the internal partition 140 of the chassis 110 divides the space horizontally or vertically into independent first chambers (exhaust chambers) and second chambers (intake chambers). This partitioning physically isolates the exhaust and intake functional modules of the main unit, avoiding airflow interference. The clean air drawn into the intake chamber will not be contaminated by the exhaust gas in the exhaust chamber, ensuring the high efficiency of the ventilation system. At the same time, the relatively enclosed space of each chamber after partitioning, combined with the sound insulation panels to enhance noise reduction, also allows for targeted operation during maintenance, improving equipment management efficiency and optimizing the utilization of internal space and operational stability of the main unit cabinet.
[0043] In this embodiment, the cabinet door 120 includes an inspection door 122 and a magnetic door 121. The inspection door 122 is located in the first chamber, and the magnetic door 121 is located in the second chamber. The inspection door 122 has a rectangular structure, and a groove is provided at the top of the inspection door 122. The two sides and the top of the inspection door 122 extend into the body 110 with first extension portions, and the first extension portion on the left side of the inspection door 122 is connected to the sound insulation plate. The magnetic door 121 has a rectangular structure. A second extension is provided on the top of the inspection door 122, the sides and bottom of the magnetic door 121, extending towards the body 110. The second extension on the left side of the magnetic door 121 is connected to the sound insulation plate. The inspection door 122 and the magnetic door 121 are manufactured in rectangular structures according to the opening dimensions of the first and second chambers, respectively. The inspection door 122 corresponds to the first chamber, and the magnetic door 121 corresponds to the second chamber and is installed on the top of the inspection door 122. An opening matching the groove size is pre-set on the top of the inspection door 122. Simultaneously, the sides and top of the inspection door 122 extend towards the body 110, and the first extension on the left side of the inspection door 122 is fixedly connected to the sound insulation plate of the body 110 via hinges, ensuring that the inspection door 122 forms a stable sealing structure with the body 110 when closed. During the manufacturing of the magnetic door 121, second extensions are made extending from its sides and bottom towards the body 110. These extensions are also connected using hinges, fixing the second extension on the left side of the magnetic door 121 to the sound insulation panel of the body 110, ensuring a stable connection between the magnetic door 121 and the body 110. This design, through the connection between the extensions and the sound insulation panel, enhances the overall integrity of the cabinet door 120 and the body 110, improving sealing and sound insulation. Furthermore, the layered arrangement of the inspection door 122 and the magnetic door 121 facilitates independent operation of different chambers.
[0044] In this embodiment, the sound insulation panel includes a first sound insulation panel 130 and a second sound insulation panel. The first sound insulation panel 130 is disposed on both sides of the body 110. The first extension on the left side of the access door 122 is connected to the first sound insulation panel 130 on the left side of the body 110. The second extension on the left side of the magnetic door 121 is connected to the first sound insulation panel 130 on the left side of the body 110. The second sound insulation panel is disposed on the inner wall of the access door 122. In the construction of the sound insulation system, polyester fiber sound-absorbing board is selected as the core material. In actual assembly, the first sound insulation panel 130 is first tightly attached to the outer walls of both sides of the body 110 by adhesive to form a basic sound insulation barrier. The first extension on the left side of the access door 122 is designed as a connection structure that matches the first sound insulation panel 130 on the left side. It is connected by a hinge so that the access door 122 can be seamlessly connected with the first sound insulation panel 130 when closed, blocking noise leakage from the door gap. The second extension on the left side of the magnetic door 121 also uses this connection method, forming a continuous sound insulation surface with the first sound insulation panel 130 on the left. The second sound insulation panel is fixed to the inner wall of the access door 122 by adhesive, further absorbing noise reflection in the area of the access door 122 and enhancing the local sound insulation effect. This synergistic design of the double sound insulation panels and the extension effectively improves the overall sound insulation performance of the main unit cabinet and reduces noise interference to the outside world.
[0045] In this embodiment, a plastic filler block 210 and a partition plate 220 are also included. The plastic filler block 210 is disposed in the top groove of the access door 122, and the shape of the plastic filler block 210 matches the groove. The partition plate 220 has an L-shaped structure and is disposed on the second sound insulation board. The partition plate 220 and the second sound insulation board form a storage space. In the design and application of the top groove of the access door 122, a plastic filler block 210 with moderate density and good sound insulation performance (such as polyurethane foam) is customized according to the precise size and shape of the groove. During installation, the plastic filler block 210 is tightly embedded in the folding handle groove at the top of the door panel. Utilizing the sound absorption and vibration damping properties of the plastic material, it fills the cavity in the groove on the one hand, blocking the path of noise transmission through the groove gaps; on the other hand, it absorbs the vibration generated by the opening and closing of the door panel or the operation of the equipment, reducing secondary noise caused by vibration. Simultaneously, an L-shaped partition 220 is fixed to the second sound insulation board on the inner wall of the inspection door 122 by welding or bolting, so that it forms a storage space with the second sound insulation board. This space can be used to store small items such as filters and tools, improving space utilization and making experimental consumables more organized.
[0046] Furthermore, such as Figure 2As shown, a plastic filler block 210 with a suitable shape is embedded in the groove at the top. The sound insulation and shock absorption properties of plastic are used to fill the cavity of the groove, block the noise transmission path, and enhance the stability of the groove structure. The L-shaped partition 220 is installed on the surface of the second sound insulation board. By bending its shape, it surrounds the sound insulation board to form a small storage space, which can be used to store small experimental items such as filters and tools. On the basis of optimizing the sound insulation performance of the maintenance door 122, the space utilization value is explored, making the door panel more functional and meeting the dual needs of experimental equipment for noise reduction and practicality.
[0047] In this embodiment, a touchscreen 180 is also included. The touchscreen 180 has a rectangular structure, and a first through hole is provided in the center of the magnetic door 121. The touchscreen 180 is installed on the magnetic door 121 through the first through hole. During the manufacturing stage of the magnetic door 121, the first through hole, which is adapted to the size of the touchscreen 180, is pre-made in the center. When installing the touchscreen 180, the touchscreen 180 with a fixing component (such as a rubber sealing ring) is first aligned with the through hole, so that the fixing component fits tightly against the hole wall. The elastic deformation of the fixing component or the mechanical locking structure is used to firmly embed the touchscreen 180 into the magnetic door 121. This embedded design makes the touchscreen 180 the core area for human-computer interaction, facilitating quick operation by the operator on the front of the device. It also reduces the damage to the screen caused by external collisions and dust thanks to the structural protection of the magnetic door 121. For subsequent maintenance, the touchscreen 180 can be easily removed from the embedded slot by gently pushing it outward, making the operation simple and reducing the difficulty of maintenance.
[0048] In this embodiment, a second through hole and a third through hole are provided at the top of the body 110 away from the magnetic door 121. The return air pipe 150 of the multi-fan main unit passes through the second through hole of the body 110 and is located at the top of the body 110. The exhaust air pipe 160 of the multi-fan main unit passes through the third through hole of the body 110 and is located at the top of the body 110. A fourth through hole is provided at the bottom of the body 110 away from the maintenance door 122. The supply air pipe 170 of the multi-fan main unit passes through the fourth through hole of the body 110 and is located at the bottom of the body 110. At the top of the body 110 away from the magnetic door 121, the second through hole and the third through hole are precisely opened according to the pipe diameter and direction of the return air pipe 150 and the exhaust air pipe 160 of the multi-fan main unit. At the bottom of the body 110 away from the maintenance door 122, the fourth through hole is opened. During actual assembly, the return air duct 150 is first inserted into the top of the unit body 110 through the second through hole. Its input end is sealed to the exhaust gas outlet of the rat cage, and its output end extends to the return air high-efficiency filter chamber, forming an exhaust gas conveying channel. The exhaust duct 160 passes through the third through hole, with one end connected to the exhaust chamber outlet and the other end leading to the external environment. The supply air duct 170 is installed at the bottom of the unit body 110 through the fourth through hole. Its input end is connected to the inlet air high-efficiency filter chamber, and its output end can extend to the experimental area. During operation, the exhaust gas in the rat cage is transported to the return air high-efficiency filter chamber through the return air duct 150, where it is filtered step by step through the high-efficiency filter screen to remove pollutants such as dust and microorganisms. The purified air enters the exhaust chamber for further treatment and is then discharged through the exhaust duct 160. This airflow organization method of "return air duct 150 inlet and exhaust air duct 160 outlet", combined with the bottom air supply duct 170 to deliver fresh air, forms a scientific air circulation path, which not only ensures the air quality of the experimental environment, but also avoids the secondary pollution caused by the retention of exhaust gas in the equipment. It fully demonstrates the rationality and efficiency of the multi-fan main cabinet in the ventilation system design.
[0049] In this embodiment, first magnetic strips are provided on the sides and bottom of the magnetic door 121, extending into second extension portions. A second magnetic strip is provided inside the front end of the second chamber. The positions of the first and second magnetic strips match. The first magnetic strips are fixed in place by embedding in the second extension portions extending from the sides and bottom of the magnetic door 121. Correspondingly, second magnetic strips are installed on the inner wall of the front end of the second chamber according to the position and spacing of the first magnetic strips. After assembly, when the magnetic door 121 is closed, the first and second magnetic strips are tightly attracted by magnetic force, making the magnetic door 121 seamlessly fit with the front end of the second chamber. This simplifies the operation process, eliminates the need for additional force, reduces air and sound leakage from gaps, improves the sealing and stability of the equipment, and ensures that the airflow in the chamber circulates along a predetermined path.
[0050] In this embodiment, a base plate 190 is also included, with the main body 110 positioned on top of the base plate 190. A pre-set distance is maintained between the bottom of the main body 110, away from the access door 122, and the top of the base plate 190 to accommodate the air supply duct 170 of the multi-fan main unit. When the base plate 190 is assembled at the bottom of the main body 110, it is connected by bolts to securely unite the base plate 190 with the main body 110. During the design phase, the outer diameter of the air supply duct 170 is pre-calculated, ensuring a 5-10cm distance is reserved between the bottom of the main body 110, away from the access door 122, and the top of the base plate 190, forming a dedicated space for accommodating the air supply duct 170. This design avoids direct contact between the air supply duct 170 and the ground, reducing the risk of wear and contamination, and facilitates the installation and maintenance of the air supply duct 170. Simultaneously, it makes the overall structure of the main unit cabinet more compact, fully utilizing vertical space and improving the applicability of the equipment in limited experimental spaces.
[0051] In this embodiment, casters 200 are also included. These casters 200 are located at the bottom of the base plate 190. Multiple casters 200 are installed at the bottom of the base plate 190. First, pre-set installation positions are made at the bottom of the base plate 190. Suitable load-bearing casters 200 are selected, typically four in a rectangular arrangement, and fixed to the installation positions with bolts. The load-bearing capacity of each caster 200 must be greater than 1 / 4 of the total weight of the main unit cabinet when fully loaded to ensure smooth equipment movement. The casters 200 must have 360° steering capability and a braking structure to facilitate operators in moving the main unit cabinet, adjusting the equipment position, and adapting to different experimental site layouts. The braking structure locks the wheels to prevent accidental slippage and ensures safe use. After installation, the bottom of the casters 200 should extend 1-2 cm beyond the edge of the base plate 190 to prevent friction between the edge of the base plate 190 and the ground, extending the equipment's service life.
[0052] In this embodiment, the body 110 is made of stainless steel. 304 stainless steel is selected and processed using this material, as it possesses excellent corrosion resistance, strength, and toughness, making it suitable for the long-term use requirements of laboratory animal husbandry equipment. The stainless steel sheet is processed into a hollow structure with an open front end through laser cutting, bending, and welding. Full welding is used at the weld joints, followed by polishing to ensure the airtightness and surface smoothness of the body 110, preventing dust accumulation and bacterial growth. The wall thickness of the body 110 is designed to be 1.5-2mm, ensuring structural strength without excessively increasing the equipment's weight. After processing, the surface of the body 110 undergoes electrolytic polishing or wire drawing to improve aesthetics, enhance corrosion resistance, and extend the equipment's service life.
[0053] This utility model's multi-fan main unit cabinet achieves significant comprehensive effects through a series of meticulously designed structures. Its stainless steel body, combined with a hollow design with a front opening and through holes on the top, sides, and bottom, provides suitable installation space and connection channels for the multi-fan main unit and related ductwork, ensuring smooth airflow circulation. The cabinet doors are divided into an inspection door and a magnetic door, corresponding to the first and second chambers respectively. The plastic filler block in the groove at the top of the inspection door enhances sound insulation, while the magnetic strip design of the magnetic door ensures a tight closure. The rationally arranged sound insulation panels, including the first sound insulation panels on both sides of the unit and the second sound insulation panel on the inner wall of the inspection door, along with the extensions of the inspection door and the magnetic door, form a good sound barrier, effectively reducing noise transmission. The partition panels and the second sound insulation panels create storage space, improving space utilization. The touchscreen facilitates operation, while the base plate and casters enhance the equipment's mobility. These designs work together to achieve multiple benefits, including stable housing of multiple fan units, efficient sound insulation, convenient operation, and flexible relocation, thus meeting the equipment usage requirements of the experimental environment.
