Technical Field

[0001] This utility model belongs to the technical field of animal cage air intake systems, specifically relating to an adjustable air intake system for animal cages. Background Technology

[0002] Animal breeding for experiments is a crucial part of research on human diseases and biomedical research and development. With the development of biomedical technology, higher requirements are being placed on animal experiments. Improving the quality of laboratory animals to ensure the accuracy of experimental results and protect the health and safety of experimental personnel are the basic requirements for animal experiments.

[0003] In animal experiments, animal cages are an indispensable piece of experimental equipment used to house laboratory mice in order to obtain accurate scientific research data.

[0004] Existing animal cages typically rely on a passive air vent at the top for the exchange of air between the inside and outside. This exchange is quite limited, resulting in poor air circulation at the bottom inside the cage, which can easily lead to the growth of bacteria and other harmful substances, affecting the health of the experimental animals inside. Utility Model Content

The adsorption plate is fixed on the side of the first baffle away from the second baffle, or on the side of the second baffle away from the first baffle, or on the opposite side of the first baffle and the second baffle.

[0014] Optimally, it also includes a connecting assembly that sequentially connects the blower, the filter assembly, and the adsorption assembly.

The sleeve is fixedly sleeved on the rotating shaft, and the rotating shaft is perpendicular to the axis of the adjustment tube.

[0016] Optimally, the filter assembly further includes a primary filter plate and a secondary filter plate that are inclinedly fixed inside the filter tube, a primary filter hole penetrating the primary filter plate, and a secondary filter hole penetrating the secondary filter plate.

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0031] like Figure 1 The diagram shows an adjustable air intake system for animal cages according to this invention. This air intake system can be connected to a single animal cage or to the main air intake of the entire animal cage frame (multiple animal cages are fixed on the animal cage frame, and the main air intake of the animal cage frame is connected to each animal cage through a flexible hose). This system facilitates air circulation within the cages while allowing for airflow adjustment to prevent excessive airflow from entering the animal cages and causing adverse effects on the animals and the cage environment.

[0032] The air intake system includes a blower 3, an adjustment component, a connecting component, a filter component, and an adsorption component. The blower 3 has an air inlet and an air outlet. The blower 3 draws in air through the air inlet and then discharges it through the air outlet, providing air to the animal cages. The adjustment component is fixed to the air inlet of the blower 3 and is used to adjust the air intake volume of the blower 3, thereby regulating the airflow entering the animal cages.

[0033] The filter assembly is fixed at the air outlet of the blower 3 to filter the exhaust air and remove impurities such as lint and other larger particles contained in the air. The adsorption assembly is fixed on the side of the filter assembly away from the blower 3 to adsorb and purify the filtered air and adsorb harmful substances contained in the air.

[0034] There are multiple sets of connecting components, which are used to connect the blower 3 and the filter component, the filter component and the adsorption component respectively. By setting the connecting components, it is convenient to disassemble and perform maintenance and replacement; on the other hand, it improves the sealing ability of the connection and prevents external air from entering the pipe through the gaps in the connection.

[0035] like Figure 2-5 The diagram shows the structure of the adjustment assembly, which includes an adjustment pipe 22, a first fixing plate 23, a push cylinder 24, a second fixing plate 25, a bearing seat 26, a rotating shaft 27, a connecting plate 28, an adjustment plate 29, and a sleeve 30. The adjustment pipe 22 is preferably a cylindrical pipe, which is fixed to the air inlet side of the blower 3 by screws. The first fixing plate 23 is fixed to one side of the adjustment pipe 22 by welding. The first fixing plate 23 is Z-shaped and extends away from the blower 3, providing sufficient installation space for the push cylinder 24.

[0036] The second fixing plate 25 is fixed to the outside of the regulating pipe 22 by welding and is arranged opposite to it. The second fixing plate 25 is in the shape of "]", and the opening side of the "]" shaped second fixing plate 25 faces the regulating pipe 22. The bearing seat 26 is fixed to the second fixing plate 25 by screw fastening (a bearing is installed in the bearing seat 26 to ensure the normal rotation of the rotating shaft 27).

[0037] The rotating shaft 27 passes through the adjusting tube 22 and is installed inside the bearing seat 26. The axis of the rotating shaft 27 is perpendicular to that of the adjusting tube 22. The connecting plate 28 is fixed to the end of the rotating shaft 27 near the first fixed plate 23 by welding. The cylinder body of the pushing cylinder 24 is pivotally connected to the first fixed plate 23. The piston rod of the pushing cylinder 24 is pivotally connected to the connecting plate 28 (the pushing cylinder 24 can be a commercially available linear cylinder).

[0038] The adjusting plate 29 is circular, and the sleeve 30 is integrally connected to the adjusting plate 29. The sleeve 30 has a hollow structure, and the diameter of the rotating shaft 27 is equal to the inner diameter of the sleeve 30. Corresponding through holes are opened on the rotating shaft 27 and the sleeve 30. After the rotating shaft 27 passes through the sleeve 30, the rotating shaft 27 and the sleeve 30 are fixed by bolts and nuts (specifically, the bolts are passed through the corresponding through holes on the rotating shaft 27 and the sleeve 30, and then nuts are used on the other side to fix the two).

[0039] When the cylinder 24 extends or retracts, it drives the shaft 27 to rotate, which in turn drives the adjusting plate 29 to flip, thereby changing the air intake area of ​​the adjusting cylinder, adjusting the air intake volume of the blower 3, and thus adjusting the air volume entering the animal cage.

[0040] The filter assembly is fixed to one side of the air outlet of the blower 3. The filter assembly includes an air inlet pipe 4, an expansion pipe 5, a filter pipe 6, a primary filter plate 7, a primary filter hole 8, a secondary filter plate 9, and a secondary filter hole 10. The air inlet pipe 4 is connected to the air outlet of the blower 3 through a connecting assembly. The expansion pipe 5 is integrally connected to the side of the air inlet pipe 4 away from the blower 3. The diameter of the expansion pipe 5 gradually increases (that is, the diameter of the expansion pipe 5 on the side closer to the blower 3 is smaller than the diameter on the side farther away from the blower 3, so the air blown in by the blower 3 can more easily enter the filter pipe 6 for filtration).

[0041] The filter tube 6 is integrally connected to the side of the expander tube 5 away from the air inlet tube 4, such as... Figure 7 As shown, the primary filter plate 7 and the secondary filter plate 9 are fixed at an angle to the inner wall of the filter tube 6 by welding, with the primary filter plate 7 close to the expansion tube 5. The primary filter holes 8 are arranged around and penetrate the primary filter plate 7, and the secondary filter holes 10 are arranged around and penetrate the secondary filter plate 9. The diameter of the primary filter holes 8 is larger than the diameter of the secondary filter holes 10 (the air blown in by the blower 3 is first filtered by the primary filter plate 7, and then filtered by the secondary filter plate 9).

[0042] By setting the inclined primary filter plate 7 and secondary filter plate 9, impurities are more likely to fall onto the inner wall of the filter tube 6 under the action of gravity when filtering air, thus preventing impurities from adhering to the surface of the filter plates and affecting the filtration effect.

[0043] The adsorption assembly is fixed to the side of the filter tube 6 away from the blower 3 via a connecting assembly. The adsorption assembly includes an adsorption tube 11, a first baffle 12, a second baffle 13, and an adsorption plate 14, as shown below. Figure 8 As shown, the first baffle 12 and the second baffle 13 are fixed to the inner wall of the adsorption tube 11, and the first baffle 12 and the second baffle 13 are respectively close to the two sides of the adsorption tube 11 (specifically, the first baffle 12 and the second baffle 13 are both annular and fixed to the inner wall of the adsorption tube 11 by welding, and threaded holes are opened on the first baffle 12 and the second baffle 13 for fixing the adsorption plate 14).

[0044] The adsorption plate 14 is an activated carbon plate. By setting the adsorption plate 14, the filtered air is adsorbed and purified to adsorb harmful substances contained in the air.

[0045] There are three ways to install the adsorption plate 14. The first way is to fix it to the side of the first baffle 12 away from the second baffle 13. The second way is to fix it to the side of the second baffle 13 away from the first baffle 12. The third way is to fix it to the opposite side of the first baffle 12 and the second baffle 13. (Specifically, the baffle has a threaded hole, and the adsorption plate 14 has a through hole that matches the threaded hole. In actual installation, the adsorption plate 14 is placed against the outside of the baffle, and then the fastening bolt is passed through the through hole on the adsorption plate 14 and screwed into the threaded hole of the baffle to fix the adsorption plate 14.)

[0046] In this embodiment, the first baffle 12 is close to the air inlet side of the adsorption tube 11, and the second baffle 13 is close to the air outlet side of the adsorption tube 11.

[0047] For the first fixing mode (i.e., the adsorption plate 14 is fixed on the side of the first baffle 12 away from the second baffle 13, and the adsorption plate 14 is not fixed on the second baffle 13), this fixing mode is suitable for high-concentration and easily adsorbed pollutants in the surrounding environment because the adsorption plate 14 is close to the air inlet of the adsorption tube 11. The adsorption plate 14 is close to the air inlet to quickly reduce the concentration of pollutants.

[0048] For the second fixing mode (that is, the adsorption plate 14 is fixed on the side of the second baffle 13 away from the first baffle 12, and the adsorption plate 14 is not fixed on the first baffle 12), this fixing mode is suitable for low-concentration and difficult-to-adsorb pollutants in the surrounding environment because the adsorption plate 14 is far away from the air inlet of the adsorption tube 11. The adsorption plate 14 is placed at a position slightly away from the air inlet to ensure sufficient adsorption time and uniform contact with the air.

[0049] The third fixing mode (the adsorption plates 14 are fixed on opposite sides of the first baffle 12 and the second baffle 13 respectively, that is, the adsorption plates 14 are fixed on both the first baffle 12 and the second baffle 13) combines the advantages of the previous two fixing modes, and the adsorption is more thorough, which is suitable for occasions with higher requirements for the quality of the air introduced into the cage.

[0050] The exhaust duct 15 is fixed to the side of the adsorption tube 11 away from the filter tube 6 via a connecting assembly. A reducing tube 16 is integrally connected to one side of the exhaust duct 15. The diameter of the reducing tube 16 gradually decreases, meaning the diameter of the reducing tube 16 on the side closer to the exhaust duct 15 is larger than the diameter on the side farther from the exhaust duct 15. A connecting tube 17 is integrally connected to the side of the reducing tube 16 away from the exhaust duct 15. The reducing tube 16 achieves a change in the diameter of the exhaust channel. The connecting tube 17 is then connected to a separate animal cage via a flexible hose, or to the main air inlet of the entire animal cage frame.

[0051] There are multiple sets of connecting assemblies, used to connect the blower 3 and the filter assembly, and the filter assembly and adsorption assembly respectively. By setting up these connecting assemblies, disassembly and maintenance / replacement are facilitated; furthermore, the sealing ability at the connection points is improved, preventing external air from entering the pipe through gaps in the connections. For example... Figure 6 The connecting assembly includes a first flange 18, a second flange 19, a sealing groove 20, and a sealing ring 21.

[0052] A sealing groove 20 is provided on the opposite side of the first flange 18 and the second flange 19, and a sealing ring 21 is disposed in the sealing groove 20. Through holes are provided around the first flange 18 and the second flange 19. The first flange 18 and the second flange 19 are fixedly connected by the cooperation of fastening bolts and nuts. The sealing ring 21 improves the sealing ability between the first flange 18 and the second flange 19, preventing external air from entering the pipeline through gaps at the connection.

[0053] like Figure 1 As shown, the first flange 18 is fixed to one side of the filter tube 6 by welding, and the second flange 19 is fixed to one side of the adsorption tube 11 by welding (similarly, the first flange 18 is fixed to the other side of the adsorption tube 11 by welding, and the second flange 19 is fixed to one side of the exhaust pipe 15 by welding).

[0054] The base plate 1 and support frame 2 are used to support the various components (specifically, the base plate 1 is fixed to the ground by bolts, the support frame 2 is fixed to the top of the base plate 1 by welding, the blower 3 is fixed to the top of the support frame 2 by screws, and the bottom of the filter pipe 6, adsorption pipe 11 and exhaust pipe 15 are welded with pads, which are fixed to the top of the support frame 2 by screws).

[0055] This utility model relates to an adjustable air intake system for animal cages. By installing an adjustment component at the air inlet of the blower 3, the air intake volume of the blower 3 can be adjusted. This facilitates air circulation within the cage and also regulates the air volume entering the animal cage, preventing excessive airflow that could cause dust, excrement, and other substances to fly around and affect the growth of the animals inside. At the same time, by setting up filter and adsorption components, the blown air is filtered and purified to remove impurities and harmful substances, thereby improving air cleanliness.

[0056] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
