Abstract
Description
Technical Field
[0001] This utility model belongs to the field of biotechnology, specifically relating to a hydrostatic balance box and a feeding system. Background Technology
[0002] Mice are a vital biological resource in biological and medical research fields, with a huge market demand. Large-scale breeding and rearing activities require a uniform and efficient air exchange environment for feeding cage clusters, achieving efficient dehumidification and temperature control to meet the daily growth and activity needs of mice. Existing cage systems use centralized air supply and exhaust, resulting in significantly different airflow rates in cages at different locations. This leads to excessively slow air exchange in some cages, resulting in excessive humidity, insufficient oxygen, and a damp environment, which are detrimental to the survival, growth, and development of mice.
[0003] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a static pressure balance box and a feeding system.
[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0006] To achieve the above objectives, the technical solution provided by a specific embodiment of this utility model is as follows:
[0007] A static pressure balance box is used to achieve stable gas exchange inside the feeding cage. It includes an outer box and an inner box isolated inside the outer box. The outer box has an air inlet and an air outlet. The air inlet is connected to the first inner cavity of the outer box, and the air outlet is connected to the second inner cavity of the inner box.

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0024] like Figure 1-4 The diagram illustrates the feasibility of applying the static pressure balance box and feeding system in one embodiment of this utility model. Wherein... Figure 1 (The figure shows a case where one wall is missing; this wall can be independent or part of a complete equipment support.) The static pressure balance box shown is used to achieve stable gas exchange inside the feeding cage. It includes an outer box 20 and an inner box isolated in the outer box 20. The outer box 20 has an air inlet 21 and an exhaust 31. The air inlet 21 communicates with the first inner cavity of the outer box 20, and the exhaust 31 communicates with the second inner cavity of the inner box. The inner box has several air supply pipes 22 that penetrate its main structure and are used to connect the first inner cavity and the feeding cage. The inner box also has several exhaust pipes 32 that are used to connect the second inner cavity and the feeding cage.
[0025] Furthermore, as a possible solution such as Figure 3 and 4 The inner casing shown includes a dry casing 33 connected to an exhaust port and a branch casing 34 formed in communication on the dry casing 33 and extending around it, wherein the branch casing 34 can be connected to the dry casing 33 via a mating interface 331. The mating interface 331 achieves a sealed connection, which can be achieved by welding or fasteners (such as flanges) mating with a seal.
[0026] Furthermore, the branch box 34 can be arranged symmetrically or asymmetrically on the trunk box 33 (relative to the trunk box). For example... Figure 3 The branch boxes 34 shown are symmetrically arranged on both sides of the trunk box 33, and the extension direction of several branch boxes 34 to the outside of the trunk box 33 is parallel to the extension direction of one side wall of the outer box 20.
[0027] Furthermore, such as Figure 3 As shown, when viewed along the extension direction of the branch box 34, the cross-sectional areas of the inner cavity of the branch box 34 are either unequal or equal. The figure shows the cross-sectional area of the inner cavity of the branch box 34, which linearly decreases away from the main box 33, as shown in a1 and a2. This can be regarded as a right-angled trapezoidal box, so the airflow at the far end can be regarded as being in a compressed state. The case shown in b1 is a cubic box structure, that is, the cross-sectional area of the inner cavity is constant.
[0028] Furthermore, such as Figure 3 The diagram also demonstrates that when the cross-sectional area of the branch box's inner cavity decreases linearly away from the dry box, the exhaust pipes matched to the branch box may be the same or different. Generally, when the situation shown in Figure b1 is adopted, it is a cubic box structure, meaning the cross-sectional area of the inner cavity remains constant. As the exhaust pipes are arranged from the far end towards the dry box 33, their diameter decreases step by step to adaptively control the airflow. However, when the situations shown in a1 and a2 are adopted, the diameter of the exhaust pipes can also decrease step by step or remain constant as they are arranged from the far end towards the dry box 33. Airflow control can be achieved through pressure control of the branch box.
[0029] Furthermore, such as Figure 1 As shown, the outer casing 20, as well as the branch casing and the main casing, share a common plane of symmetry, meaning they have a clearly symmetrical structure (excluding the influence of the intake port 21 and the exhaust port 31), thus achieving better operational structural stability. The intake and exhaust ports can be located on the same side wall of the outer casing 20, or they can be located in different positions; for example, the intake port 21 can be located on... Figure 1 The exhaust port 31 can be located on the opposite side or in another convenient location, as shown in the image.
[0030] Furthermore, in the vicinity of the feeding cages, the side walls of the outer box 20 and the inner box are parallel, attached, or shared. Of course, the side wall can also be provided directly by the support, that is, the wall or plate of the hanging cage array, and it, the outer box 20 side wall, and the inner box side wall can overlap and be shared, or they can be separate from each other or partially shared.
[0031] like Figure 4The diagram illustrates the application of a feeding system, including a frame, several cages, and several static pressure balancing chambers (the diagram shows one static pressure balancing chamber; more chambers can be used to meet the needs of multi-faceted feeding and improve space utilization efficiency). The inner cavity of the cages is matched with the air supply and exhaust pipes of the static pressure balancing chambers. Clean air supplied by the fan enters the first inner cavity through the air supply pipe 21, and after buffering, enters the cage through the air inlet 21. After circulation, it enters the branch chamber 34 and the dry chamber 33 through the exhaust port 31, and is then discharged through the exhaust pipe 31, thus completing one cycle. This ensures the safety of the cage environment and meets the requirements of intensive cage feeding for mice and other animals.
[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
