Technical Field
[0001] The present application belongs to the technical field of air conditioning noise reduction, and in particular relates to a laboratory air conditioning noise reduction device. Background Art
[0002] To control the experimental environment and regulate human comfort during experiments, existing laboratories often install custom air conditioners for environmental regulation. Furthermore, due to the unique requirements of the laboratory environment, the air conditioner must operate continuously and provide high ventilation volumes. This often results in high noise levels in the experimental environment, which can cause disturbances to experimenters at best and even physical harm at worst. Therefore, noise reduction in laboratory air conditioners is particularly important.
[0003] Since laboratory air conditioners have different air outputs, different air outputs will produce different degrees of noise. However, the noise reduction structure of existing laboratory air conditioner noise reduction devices is fixed and cannot be adjusted for different air outputs, resulting in reduced noise reduction effect.

[0022] In order to make the purpose, technical solutions, design methods and advantages of this application more clear, the following is a further detailed description of this application through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain this application and are not used to limit this application.
[0023] It should be noted that laboratory air conditioners have different air output volumes, and the noise reduction device involved in this application is configured to adapt to different air output volumes. The adjustment structure 16 is adjusted according to the air output volume of the laboratory air conditioner, thereby achieving the noise reduction effect of different air output volumes.
[0024] Reference Figure 1 , the present application provides a laboratory air conditioning noise reduction device, including a first shell 10, a second shell 12 and an adjustment structure 16;
[0025] The first housing 10 has a cavity, and an air outlet 11 is provided on one side of the first housing 10; the second housing 12 is provided in the cavity of the first housing, and one end of the second housing 12 extends out of the first housing 10 and communicates with the air outlet 13 of the air conditioner;
[0026] The outer wall of the second housing 12 cooperates with the inner wall of the first housing 10 to form a channel 14; a plurality of air guide holes 15 are provided on the side wall of the second housing 12, and the first housing 10 is connected to the channel 14 through the air guide holes 15. An air guide duct 24 is connected to the air guide holes 15, and the air guide duct 24 is installed in the channel 14 and is connected to the air outlet end 11;
[0027] The adjustment structure 16 is disposed in the chamber 23 of the second shell 12 . The adjustment structure 16 and the second shell 12 form a sealed cavity and are slidably connected to the inner wall of the second shell 12 .
[0028] In the above, the wind from the air outlet 13 of the laboratory air conditioner enters the sealed cavity formed by the second shell 12 and the adjustment structure 16. As the pressure in the sealed cavity gradually increases, the adjustment structure 16 will be pushed toward the air outlet end 11. If the wind force is large, the adjustment structure 16 will move a long distance, and the number of air guide holes 15 that lose their seal will be greater. The gas in the sealed cavity will enter the air guide duct 24 connected to the air guide holes 15 from the exposed air guide holes 15, thereby extending the flow path of the noise, thereby improving the noise reduction effect of the laboratory air conditioner. Before blowing air, the adjustment structure 16 will seal the air guide holes 15, so that the sealed cavity is in a relatively sealed state.
[0029] In the above embodiment, referring to Figure 1 Noise reduction structures 21 are provided on both sides of the inner wall of the air duct 24. The outer surface of the noise reduction structure 21 is curved, which extends the noise propagation path and reflects and absorbs the noise through the curved outer surface structure of the noise reduction structure 21; the noise reduction structure 21 is a product in the prior art, and sound-absorbing cotton or porous sound-absorbing materials in the prior art can be selected.
[0030] As an embodiment of this application, specific reference is made to Figure 1As shown, the adjustment structure 16 includes a slider 17 and an elastic member 18; the slider 17 is slidably connected to the inner wall of the second shell 12, and the slider 17 and the second shell 12 form a sealed cavity; one end of the elastic member 18 is connected to the back of the slider 17, and the other end of the elastic member 18 is connected to the inner wall of the second shell 12; a through hole 20 is provided on the side wall of the second shell 12 near the elastic member 18, and the through hole 20 is connected to the air outlet end 11; a protrusion 19 is connected to the back of the slider 17, and the protrusion 19 is connected to the elastic member 18; a limit block 22 is provided on the inner wall of the second shell 12.
[0031] In the above, the front side of the slider 17 forms a sealed cavity with the inner wall of the second shell 12, while the back side of the slider 17 forms a low-pressure cavity with the inner wall of the second shell 12 and the through hole 20, so that the slider 17 moves more smoothly toward the air outlet end 13; the protrusion 19 on the slider 17 seals the air guide hole 15 in the initial state. As the pressure in the sealed cavity gradually increases and the potential energy of the wind blown out by the laboratory air conditioner pushes the slider 17, the elastic member 18 retracts, and conversely the elastic member 18 extends to push the slider 17 in the opposite direction, so that the protrusion 19 reseals the air guide hole 15.
[0032] It should be noted that the elastic member 18 can be a spring, and the elastic force of the spring is determined according to actual conditions.

Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
