Description

Technical Field

[0001] The utility model belongs to the technical field of air conditioners, and particularly relates to an adjustable air-conditioning pipeline silencer. Background Art

[0002] An air conditioner, that is, an air conditioner, refers to a device that uses artificial means to adjust and control parameters such as the temperature, humidity, and flow rate of the air in a building or structure; during the operation of the air conditioner, noise will be generated, and the noise will enter the interior of the air-conditioning pipeline and be discharged, which will have an adverse impact on people's working environment or sleeping environment. Therefore, an air-conditioning pipeline silencer is configured on the air-conditioning pipeline.

[0003] An air-conditioning pipeline silencer refers to a pipeline with airflow that also transmits noise. Noise reduction devices such as pipes and elbows with sound-absorbing linings or pipes with sudden changes in cross-sectional area and other acoustic impedance discontinuities can be used to attenuate or reflect back the noise inside the pipeline; air-conditioning pipeline silencers can be divided into: resistive silencers, reactive silencers, and composite silencers. As the name implies, reactive silencers use opposition to eliminate fluctuations, which is different from the resistive principle. Reactive silencers are mainly composed of partitions and expansion chambers. Generally, a silencer has three expansion chambers of different sizes, mainly using the reflection and mutual interference of waste gas in these chambers to achieve the noise reduction effect.

[0004] However, it still has the following drawbacks in actual use:

[0005] In the existing air-conditioning pipeline silencer, during use, by setting an impact chamber inside the air-conditioning pipeline silencer, the noise is impacted and consumed inside the impact chamber, thereby achieving the purpose of noise reduction inside the air-conditioning pipeline. However, the external length of the existing air-conditioning pipeline silencer cannot be adjusted according to the actual situation, which reduces the scope of use of the existing air-conditioning pipeline silencer, and further reduces the practicability of the existing air-conditioning pipeline silencer;

[0006] 2. In the existing air-conditioning pipeline silencer, during use, by setting an impact chamber inside the air-conditioning pipeline silencer, the noise is impacted and consumed inside the impact chamber, thereby achieving the purpose of noise reduction inside the air-conditioning pipeline. However, the method of weakening noise is too single, and the noise weakening effect is not good.

[0007] Therefore, we provide an adjustable air-conditioning pipeline silencer to solve the above problems. Content of the Utility Model

[0008] The purpose of the utility model is to provide an adjustable air-conditioning pipeline silencer, which solves the problems of low practicability and poor noise reduction effect of the existing air-conditioning pipeline silencer by setting an adjustment component and a buffer component.

[0009] To solve the above technical problems, the present utility model is achieved through the following technical solutions:

[0010] The present utility model is an adjustable air-conditioning pipeline silencer, including a connecting ring. The adjusting assembly arranged on the side of the connecting ring includes a reverse sleeve and a forward sleeve.

An ear block connected to the end of the forward screw cylinder is connected to the outer peripheral side wall of the forward sleeve, and an ear block connected to the end of the reverse screw cylinder is connected to the outer peripheral side wall of the reverse sleeve.

[0012] The present utility model is further arranged such that inner telescopic pipes are communicated with the connecting pipe, the discharge pipe, and the inlet pipe, and through holes are opened on the connecting pipe, the discharge pipe, and the inlet pipe.

[0013] The present utility model is further arranged such that two inner telescopic pipes are provided on the connecting pipe, the discharge pipe, and the inlet pipe.

[0020] By providing a buffer assembly in the present utility model, the noise entering the reverse sleeve through the inlet pipe contacts the buffer plate on the reverse plate, and the damper cooperates with the shock-absorbing spring to work, slowing down the impact force between the buffer plate, the forward plate and the reverse plate, reducing the vibration noise, and the noise is absorbed by the sound-absorbing plate to further reduce the noise, and the noise is consumed by the impact between the reverse movable plate and the buffer plate, and the noise is consumed by the impact between the forward movable plate and the buffer plate, further reducing the noise, thereby enhancing the sound-absorbing effect of the adjustable air-conditioning pipeline silencer.

[0032] Specifically, an outer telescopic tube 204 is connected between the reverse sleeve 203 and the connecting ring 1, and an outer telescopic tube 204 is connected between the forward sleeve 205 and the connecting ring 1.

[0038] The operation process of this embodiment is as follows: Noise impacts the buffer plate 401, and the damper 402 cooperates with the shock-absorbing spring 402a to work, slowing down the impact force between the buffer plate 401, the reverse plate 209a, and the forward plate 209c, achieving noise weakening. At the same time, the sound-absorbing plate 401a absorbs noise, achieving noise weakening, and the noise is consumed by impacting between the buffer plate 401 and the reverse movable plate 209b, and the noise is consumed by impacting between the buffer plate 401 and the forward movable plate 209d, achieving noise weakening.
