Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an air circulation fan for an incubator of a blood culture instrument. Background Art

[0002] The fully automatic blood bacterial culture instrument is a rapid microbial culture system that can quickly and sensitively detect pathogenic microorganisms in the blood of patients with sepsis, bacteremia, etc. It can also detect pathogenic microorganisms in normal sterile parts of the body (thoracic cavity, abdominal cavity, joint cavity, pericardial cavity, cerebrospinal cavity, etc.), providing a diagnostic basis for rapid and effective clinical anti-infection treatment. For example, an incubator for a fully automatic blood culture instrument is mentioned in application number CN201920621958.0.

[0003] In the existing blood culture incubator, an air circulation fan is usually used to circulate the internal air to improve the air circulation environment inside the blood culture incubator. When the air circulation fan is in operation, it is connected to the motor through a shaft, and the shaft is driven by the motor to rotate to achieve synchronous rotation of the fan barrel of the circulation fan. However, since the overall weight of the fan barrel is greater than the weight of the shaft, the centrifugal force during rotation will cause the shaft and the surrounding shell to collide, resulting in instability.

[0004] Therefore, it is necessary to design an air circulation fan for a blood culture incubator to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide an air circulation fan for an incubator of a blood culture instrument, so as to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A blood culture incubator air circulation fan comprises a fan barrel, which is composed of a plurality of arc-shaped fan blades. Side mounting plates are arranged on the left and right sides of the fan barrel. The left and right sides of the fan barrel and the side mounting plates are fixedly connected by connecting rods and connecting sleeves. The side mounting plate on one side is away from a driving shaft on one side of the fan barrel, and a shock-absorbing cylinder is arranged on the outer side of the connecting sleeve.

[0008] As a preferred solution of the utility model, the shock absorbing cylinder is installed in the connecting sleeve, and a plurality of damping shock absorbers and springs are arranged between the outer side of the connecting sleeve and the inner side of the shock absorbing cylinder.

[0009] As a preferred solution of the utility model, the two ends of the damping shock absorber are respectively fixedly connected to the connecting sleeve and the shock absorbing cylinder, and the spring sleeve is installed on the outside of the damping shock absorber.

[0010] As a preferred solution of the utility model, a key block is arranged on the outer side of the connecting rod, a key slot used in conjunction with the key block is opened inside the connecting sleeve, and the connecting rod and the connecting sleeve are key-connected via the key block and the key slot.

[0011] As a preferred solution of the utility model, the fan barrel and the arc-shaped fan blades are both made of stainless steel, and the arc-shaped fan blades adopt an inner arc design.

[0012] As a preferred solution of the utility model, a plurality of reinforcement sleeves are arranged on the periphery of the fan cylinder, and the reinforcement sleeves are made of high-strength material.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] In the utility model, an air circulation fan of a blood culture incubator is provided. During the use of the blood culture incubator, when the air circulation fan is rotating, collision occurs between the connecting rod and the connecting sleeve due to the centrifugal force generated by the rotation of the fan barrel. At this time, the damping shock absorber and the spring are helpful to reduce the vibration, thereby improving the stability of the air circulation fan during rotation, thereby reducing the noise of the air circulation fan during rotation.

[0025] A blood culture incubator air circulation fan comprises a fan barrel 1, which is composed of a plurality of arc-shaped fan blades 2. Side mounting plates 3 are arranged on the left and right sides of the fan barrel 1. The left and right sides of the fan barrel 1 and the side mounting plates 3 are fixedly connected by connecting rods 4 and connecting sleeves 5. The side mounting plate 3 on one side is away from a driving shaft 6 on one side of the fan barrel 1, and a shock-absorbing cylinder 7 is sleeved on the outer side of the connecting sleeve 5.

[0026] For details, please refer to Figure 1 , Figure 2 as well as Figure 4 The shock-absorbing cylinder 7 is sleeved and installed on the connecting sleeve 5, and a plurality of damping shock absorbers 8 and springs 9 are arranged between the outer side of the connecting sleeve 5 and the inner side of the shock-absorbing cylinder 7; the two ends of the damping shock absorber 8 are respectively fixedly connected to the connecting sleeve 5 and the shock-absorbing cylinder 7, and the spring 9 is sleeved and installed on the outer side of the damping shock absorber 8; a key block is arranged on the outer side of the connecting rod 4, a key slot used in conjunction with the key block is opened inside the connecting sleeve 5, and the connecting rod 4 and the connecting sleeve 5 are key-connected through the key block and the key slot;

[0027] In this embodiment, when the air circulation fan is rotating, the connecting rod 4 and the connecting sleeve 5 may collide due to the centrifugal force generated by the rotation of the fan barrel 1. At this time, the damping shock absorber 8 and the spring 9 are helpful to reduce the vibration, thereby improving the stability of the air circulation fan during rotation, thereby reducing the noise of the air circulation fan during rotation.

[0028] For details, please refer to Figure 1 , Figure 2 as well as Figure 3 The fan barrel 1 and the arc-shaped fan blades 2 are both made of stainless steel, and the arc-shaped fan blades 2 are designed with an inner arc shape; a plurality of reinforcement sleeves 10 are arranged on the periphery of the fan barrel 1, and the reinforcement sleeves 10 are made of high-strength materials;

[0029] In this embodiment, since the fan barrel 1 and the arc-shaped fan blades 2 are made of stainless steel, they can avoid rust after long-term use. At the same time, the reinforcement sleeve 10 is sleeved on the outer end of the fan barrel 1, thereby improving the overall strength of the circulation fan.

[0030] Working process of the utility model: when using the air circulation fan of the blood culture incubator, the fan barrel 1 and the side mounting plates 3 on both sides are key-connected through the connecting rod 4 and the connecting sleeve 5 by means of key blocks and key slots, and the driving shaft 6 is connected to the external driving motor. When the driving motor drives the entire fan barrel 1 to rotate through the driving shaft 6, the connecting rod 4 and the connecting sleeve 5 will collide due to the centrifugal force generated by the rotation of the fan barrel 1. At this time, the damping shock absorber 8 and the spring 9 are helpful to reduce the vibration, thereby improving the stability of the air circulation fan during rotation, thereby reducing the noise of the air circulation fan during rotation. Furthermore, since the fan barrel 1 and the arc-shaped fan blades 2 are made of stainless steel, rust can be avoided after long-term use. At the same time, the reinforcement sleeve 10 is sleeved on the outer end of the fan barrel 1, thereby improving the overall strength of the circulation fan.
