[0002] Blood cell analyzers are indispensable tools in the field of medical devices, widely used in clinical diagnosis, scientific research, and health monitoring. By detecting various components in blood samples, these devices provide crucial diagnostic information for doctors and researchers.

[0003] Currently, hematology analyzers typically incorporate pumps such as air pumps and hydraulic pumps, which play a crucial role in delivering and pressurizing blood samples during operation. However, the operation of these pumps inevitably generates vibration and noise. Vibration not only affects the stability of the equipment, leading to inaccurate test results, but can also damage other components, thus shortening the lifespan of the hematology analyzer. Utility Model Content

[0004] The main purpose of this invention is to propose a shock-absorbing structure for an air pump and a blood cell analyzer, aiming to solve the problem of easy vibration of the pump body in existing blood cell analyzers.

[0005] To achieve the above objectives, the present invention proposes an air pump vibration damping structure, which includes:

[0006] Mounting plate, used for mounting on the main unit of the blood cell analyzer;

[0007] A damping plate, the end of which is fixed to the mounting plate, and the surface gap between the damping plate and the mounting plate is provided to form a suspension space; and

[0008] An air pump is fixed to the shock-absorbing plate and located above the suspension space.

[0009] In one embodiment, the shock-absorbing plate includes a main board and a positioning tongue bent and connected to the main board. The positioning tongue is detachably connected to the mounting plate. The surfaces of the main board and the mounting plate are suspended, and the air pump is mounted on the main board.

[0010] In one embodiment, the shock-absorbing plate further includes an arc-shaped plate disposed between the main board and the positioning tongue to connect the main board and the positioning tongue, and the arc-shaped plate is bent toward the mounting plate.

[0011] In one embodiment, the motherboard has a square structure, and four positioning tongues are provided, which are respectively located at the four corners of the motherboard.

[0012] In one embodiment, the air pump vibration damping structure further includes a damping column, the two ends of which are respectively connected to the positioning tongue and the mounting plate.

[0013] In one embodiment, the material of the damping plate is selected from at least one of metal, alloy, ceramic or plastic; and / or, the material of the damping column is selected from at least one of plastic, foam or rubber.

[0014] In one embodiment, the shock-absorbing column and the positioning tongue are connected by a thread; and / or, the shock-absorbing column and the mounting plate are connected by a thread.

[0015] In one embodiment, the air pump and the motherboard are connected by a threaded connection.

[0016] In one embodiment, a gap is provided between the air pump and the mounting plate.

[0017] This utility model also proposes a blood cell analyzer, which includes the air pump shock absorption structure as described in any of the above embodiments.

[0018] In this invention, a mounting plate is provided on the main unit of the blood cell analyzer. A shock-absorbing plate is installed, with its end fixed to the mounting plate while the main body of the shock-absorbing plate does not contact the mounting plate, and the gap between them forms a suspension space.

[0030] Currently, hematology analyzers typically incorporate pumps such as air pumps and hydraulic pumps, which play a crucial role in delivering and pressurizing blood samples during operation. However, the operation of these pumps inevitably generates vibration and noise. Vibration not only affects the stability of the equipment, leading to inaccurate test results, but can also damage other components, thus shortening the lifespan of the hematology analyzer.

[0031] This utility model proposes an air pump vibration reduction structure.

[0032] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the air pump shock absorption structure 100 includes:

[0033] Mounting plate 1 is used to install on the main unit of the blood cell analyzer;

[0034] A damping plate 2, the end of which is fixed to a mounting plate 1, and a surface gap between the damping plate 2 and the mounting plate 1 is provided to form a suspension space; and

[0035] Air pump 3 is fixed on shock absorber 2 and located above the suspension space.

[0036] In this invention, a mounting plate 1 is provided on the main unit of the blood cell analyzer. A shock-absorbing plate 2 is installed, with its end fixed to the mounting plate 1, while the main body of the shock-absorbing plate 2 does not contact the mounting plate 1, and the gap between them forms a suspension space. Thus, when the air pump 3 is mounted on the shock-absorbing plate 2, the suspension space effectively absorbs and buffers the vibration energy generated during the operation of the air pump 3, preventing the vibration from being directly transmitted to the main unit, thereby significantly reducing the overall vibration amplitude of the instrument and the resulting noise.

[0037] Specifically, the shape and size of the mounting plate 1 are not specifically limited. The mounting plate 1 can be a square metal plate or rubber plate that matches the mounting area on the main unit. The connection method between the main unit of the blood cell analyzer and the mounting plate 1 is not specifically limited. For example, it can be a threaded connection or a snap-fit ​​connection. When a snap-fit ​​connection is used, a slot can be provided on one of the main unit and the mounting plate 1, and a buckle can be provided on the other of the main unit and the mounting plate 1. The mounting plate 1 can be installed and fixed by the cooperation of the buckle and the slot. Alternatively, threaded holes can be provided on the mounting plate 1 and the main unit of the analyzer, and bolts can be screwed into the threaded holes to fix the two. The shape and size of the damping plate 2 are not specifically limited; its size can be adapted to the size of the base plate of the air pump 3. The damping plate 2 can be a square elastic rubber plate, preferably a synthetic rubber or other polymer material with high elasticity and good heat dissipation. One end of the damping plate 2 can be fixed to the center of the mounting plate 1 by strong adhesive or mechanical clips, so that a suspended space with gaps around the perimeter is formed between the damping plate 2 and the mounting plate 1. The height of this suspended space is at least 2cm to ensure that the damping plate 2 does not come into contact with the mounting plate 1. The air pump 3 is a square device and can be fixed above the damping plate 2 through four bolt holes, located directly above the suspended space. When the air pump 3 vibrates during operation, the damping plate 2 can absorb and buffer the vibration energy through its own elastic deformation, effectively reducing the vibration transmission efficiency.

[0038] In the embodiments of this utility model, please refer to Figure 3 The damping plate 2 includes a main board 21 and a positioning tongue 22 bent and connected to the main board 21. The positioning tongue 22 is detachably connected to the mounting plate 1. The surfaces of the main board 21 and the mounting plate 1 are suspended, and the air pump 3 is mounted on the main board 21. In this embodiment, the damping plate 2 includes a main board 21 and a positioning tongue 22. The main board 21 is the main component of the damping plate 2. The main board 21 can be made of a material with good elasticity and thermal conductivity, such as high-strength plastic or metal. The positioning tongue 22 can be connected to the main board 21 by an integral bending process, or it can be separately processed and then welded or riveted. The positioning tongue 22 is detachably connected to the mounting plate 1, for example, by bolts, clips, or other detachable fixing methods, making the installation and removal of the damping plate 2 simple and quick, and convenient for maintenance and replacement. The surfaces of the main board 21 and the mounting plate 1 are suspended, that is, they are not in direct contact, but have a certain air gap. This can reduce vibration transmission and also facilitate air circulation, reducing the operating temperature of the air pump 3. The air pump 3 is fixed on the main board 21 by bolts or screws and other fasteners. The stability of the main board 21 ensures the smooth operation of the air pump 3 and reduces noise and errors caused by vibration.

[0039] In the embodiments of this utility model, please refer to Figure 4The damping plate 2 also includes an arc-shaped plate 23, which is located between the main plate 21 and the positioning tongue 22 to connect them. The arc-shaped plate 23 is bent towards the mounting plate 1. The main plate 21 is the main load-bearing part of the damping plate 2, used to fix the air pump 3. The positioning tongue 22 is bent and connected to the main plate 21, and its function is to form a detachable connection with the mounting plate 1. By providing an arc-shaped plate 23 between the main plate 21 and the positioning tongue 22, a more robust structure is formed, increasing the elasticity of the damping plate 2, so that it can more effectively absorb and disperse vibrations when the air pump 3 is running, thereby further improving the damping effect. Furthermore, the arc-shaped plate 23 is bent towards the mounting plate 1, and the curvature of the arc-shaped plate 23 is not specifically limited, which helps to evenly transmit the pressure generated by the air pump 3 to the mounting plate 1 and reduce local pressure concentration.

[0040] In the embodiments of this utility model, please refer to Figure 4 The main board 21 has a square structure with four positioning tongues 22 located at its four corners. These tongues help to evenly distribute the weight of the air pump 3 and the vibrations generated during operation onto the mounting plate 1, reducing stress concentration at any single location. The square main board 21 is simple and robust, and the positioning tongues 22 at the four corners further enhance the rigidity of the damping plate 2, making it less prone to deformation under vibration and ensuring the durability of the damping effect. The connection between the positioning tongues 22 and the mounting plate 1 can be detachable, for example, by bolts and nuts, or by using quick-connect fasteners.

[0041] In the embodiments of this utility model, please refer to Figure 3 The air pump vibration damping structure 100 also includes a damping column 4. The two ends of the damping column 4 are connected to the positioning tongue 22 and the mounting plate 1, respectively. Due to the damping column 4, the vibration generated during the operation of the air pump 3 is further buffered. After the air pump 3 vibrates, it is first buffered by the damping plate 2, and then by the damping column 4. Through the double buffering of the damping plate 2 and the damping column 4, the residual vibration reaching the mounting plate 1 is very small, effectively improving the vibration damping effect of the air pump 3. It should be noted that multiple damping columns 4 can be provided, matching the number of positioning tongues 22; that is, each positioning tongue 22 has at least one damping column 4. Preferably, the damping column 4 is made of an elastic or compression-resistant material, such as rubber or a metal spring, so that it absorbs and buffers vibration through its own deformation when the air pump 3 vibrates during operation.

[0042] In embodiments of this utility model, the material of the damping plate 2 is selected from at least one of metal, alloy, ceramic, or plastic, and can be any one of the above materials, or a composite material of two or three of the above materials. The metal can be aluminum, copper, or iron, etc., possessing high strength and good thermal stability; the plastic can be a composite material of polyethylene and natural rubber or styrene-butadiene rubber. The damping plate 2 is preferably an elastic metal sheet with good thermal conductivity and a thickness of 0.2–1 mm. Optionally, the material of the damping column 4 is selected from at least one of plastic, foam material, or rubber, and can be any one of the above materials, or a composite material of two or three of the above materials. The damping column 4 is preferably a rubber material with excellent thermal conductivity and a height of 5–15 mm, or it can be a polyurethane elastomer, because polyurethane elastomer has a porous structure, which can effectively absorb vibration and reduce the shaking during the operation of the air pump 3.

[0043] In the embodiments of this utility model, please refer to Figure 3 and Figure 4 The damping column 4 and the positioning tongue 22 are connected by threads. For example, one end of the damping column 4 has an external thread, while the positioning tongue 22 has a corresponding internal thread hole. During installation, the external thread of the damping column 4 is screwed into the threaded hole of the positioning tongue 22, and a tight connection is achieved through the engagement of the threads. Of course, the positions of the internal and external threads can also be interchanged between the positioning tongue 22 and the damping column 4. The threaded connection allows the damping column 4 to rotate on the positioning tongue 22, thereby adjusting the length of the damping column 4 as needed to achieve the best damping effect. Optionally, the damping column 4 and the mounting plate 1 are also connected by threads. The other end of the damping column 4 is also designed with external threads, while the mounting plate 1 has a pre-set internal thread hole that matches the damping column 4. During installation, the external thread of the damping column 4 is screwed into the threaded hole of the mounting plate 1 to complete the connection. Through the threaded connection, the damping column 4 can be firmly fixed to the mounting plate 1, ensuring that the damping column 4 will not shift when absorbing vibration.

[0044] In the embodiments of this utility model, please refer to Figure 1 The air pump 3 and the main board 21 are connected by threads. For example, the bottom of the air pump 3 has external threads or threaded holes, while the top of the main board 21 has matching internal threads or bolt holes. During installation, align the threaded part of the air pump 3 with the threaded hole of the main board 21, and rotate the air pump 3 to make its threads tightly connected to the main board 21. This not only ensures the stability of the air pump 3, but also allows the position of the air pump 3 to be adjusted within a certain range to achieve the best shock absorption effect.

[0045] In the embodiments of this utility model, please refer to Figure 2A gap is provided between the air pump 3 and the mounting plate 1. This gap can be a fixed-size empty space or indirect isolation via additional parts such as gaskets, as long as direct contact between the air pump 3 and the mounting plate 1 is avoided. This helps absorb and buffer the vibrations generated by the air pump 3 during operation, preventing these vibrations from being directly transmitted to the mounting plate 1 and avoiding additional impact noise. Simultaneously, the gap also provides some heat dissipation, preventing the air pump 3 from overheating due to prolonged operation.

[0046] This utility model also proposes a blood cell analyzer, which includes an air pump vibration damping structure 100. The specific structure of the air pump vibration damping structure 100 is as described in the above embodiments. Since this blood cell analyzer adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The type of blood cell analyzer is not specifically limited; any analyzer with an air pump 3 or a liquid pump can use this vibration damping structure.

[0047] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
