Description

Technical Field

[0001] This utility model belongs to the technical field of air conditioning outlets, and particularly relates to a noise-reducing air conditioning outlet. Background Technology

[0002] Air conditioning is an indispensable device in modern life and is widely used in ordinary residential homes and shopping malls. In an air conditioning system, the air outlet is the last component connecting the indoor space, and its importance is self-evident.

[0003] The problems with existing technology are: existing air outlets transmit a lot of mechanical noise from inside the duct while air is being discharged, and the noise cannot be reduced; at the same time, when the air volume of traditional air outlets is fast and large, the air will collide directly with the air vent plate of the traditional air outlet, thus generating wind noise, which will affect the surrounding environment and cause discomfort to people. Utility Model Content

[0004] To address the problems of existing technologies, this utility model provides a noise-reducing air conditioner outlet that can reduce dust while discharging air, thereby reducing noise to a certain extent and preventing the surrounding environment from being affected. This solves the problems of existing air outlets, which transmit a large amount of mechanical noise from inside the duct while discharging air and cannot reduce noise; at the same time, when the air volume of a traditional air outlet is fast and large, the air will directly collide with the air vent plate of the traditional air outlet, thereby generating wind noise, which will affect the surrounding environment and cause discomfort to people.

[0005] This utility model is implemented as follows: a noise-reducing air conditioner outlet includes an air outlet and a pipe body. The pipe body is disposed at the rear end of the air outlet and is fixedly connected to the air outlet. A noise reduction device is disposed on the front side inside the air outlet. Placement slots are opened on both the left and right sides of the front surface of the air outlet. The noise reduction device includes a protective cover, an air outlet buffer, and an installation assembly. The protective cover is disposed on the front side inside the air outlet. There are several air outlet buffers, which are evenly disposed inside the protective cover. There are two installation assemblies, which are respectively disposed in the two placement slots.

[0006] The preferred protective cover of this utility model includes a protective frame and sound-absorbing cotton. The protective frame is disposed inside the front side of the air outlet and is movably connected to the air outlet. The sound-absorbing cotton is disposed inside the protective frame and is fixedly connected to the protective frame. By setting the protective cover, noise reduction is achieved, effectively absorbing and isolating the mechanical noise that is to be transmitted from the air outlet. The combination of the protective frame and the sound-absorbing cotton has good sound absorption and isolation performance, which can reduce the mechanical noise transmitted through the air outlet.

[0007] The preferred air outlet buffer of this utility model includes an air outlet pipe and a sound-absorbing felt. The air outlet pipe is disposed inside the protective frame and is fixedly connected to the protective frame, with both its front and rear ends penetrating the protective frame. The sound-absorbing felt is disposed inside the air outlet pipe and is fixedly connected to the inner wall of the air outlet pipe. By setting the air outlet buffer, the noise reduction function is achieved when the air is vented, so that the air is buffered as it passes through the air outlet pipe. At the same time, the sound-absorbing felt absorbs the wind noise caused by the impact and collision between the air and the air outlet pipe.

[0008] The preferred embodiment of this utility model is a continuously curved air duct. By setting the air duct to a continuously curved shape, noise will be reflected and interfered during the propagation process along the continuously curved pipe, which helps to consume noise energy and thus achieve the effect of noise reduction. At the same time, the continuous curved shape can buffer the wind and further consume energy, so that the wind speed is reduced after passing through the continuously curved pipe, and the wind noise is also reduced accordingly.

[0009] The preferred mounting assembly of this utility model includes positioning rods, lock heads, and push springs. Two positioning rods are respectively positioned on the upper and lower sides of the placement groove. The left and right ends of the two positioning rods are fixedly connected to the left and right surfaces of the placement groove, respectively. The lock head is sleeved on the left end surface of the two positioning rods and slidably connected to them. The left end of the lock head extends into the air outlet and is movably connected to it. Two push springs are respectively sleeved on the surfaces of the two positioning rods. The left and right ends of the two push springs are fixedly connected to the right side of the lock head and the right surface of the placement groove, respectively. This mounting assembly is used to fix the protective frame, facilitating quick installation and subsequent disassembly of the protective frame.

[0010] As a preferred embodiment of this utility model, the left and right sides of the protective frame are provided with mating grooves. The positions of the two mating grooves correspond to and are adapted to the positions of the two mounting components. By providing mating grooves on the left and right sides of the protective frame, it is used to engage with the mounting components, thereby achieving quick fixation of the protective frame during installation.

[0011] As a preferred embodiment of this invention, a pull button is fixedly connected to the front surface of the lock head. The front end of the pull button extends out of the placement groove and is movably connected to the placement groove. By fixing the pull button to the front surface of the lock head, the lock head can be pulled to release the lock head from the protective frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model solves the problem of existing air outlets transmitting a large amount of mechanical noise from inside the pipe while discharging air, without noise reduction, by setting up an air outlet, pipe body, noise reduction device, protective cover, protective frame, sound-absorbing cotton, air outlet buffer, air outlet pipe, sound-absorbing felt, installation components, positioning rod, lock head, push spring, placement groove, docking groove and pull button in combination. At the same time, when the air volume of traditional air outlets is fast and large, the wind will directly collide with the air plate of the traditional air outlet, thus generating wind noise, which will affect the surrounding environment and cause discomfort to people.

Detailed Implementation

[0019] To further understand the invention content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0020] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown in the figure, the present invention provides a noise-reducing air conditioner outlet, including an outlet 1 and a pipe body 2. The pipe body 2 is located at the rear end of the outlet 1 and is fixedly connected to the outlet 1. A noise reduction device 3 is provided on the front side inside the outlet 1. Placement slots 4 are provided on both the left and right sides of the front surface of the outlet 1. The noise reduction device 3 includes a protective cover 31, an air outlet buffer 32 and an installation component 33. The protective cover 31 is located on the front side inside the outlet 1. There are several air outlet buffers 32, which are evenly arranged inside the protective cover 31. There are two installation components 33, which are respectively arranged in two placement slots 4.

[0022] refer to Figure 1 and Figure 2 The protective cover 31 includes a protective frame 311 and a sound-absorbing cotton 312. The protective frame 311 is located inside the front side of the air outlet 1 and is movably connected to the air outlet 1. The sound-absorbing cotton 312 is located inside the protective frame 311 and is fixedly connected to the protective frame 311.

[0023] The above solution is adopted: by setting up the protective cover 31, the noise reduction function is used to effectively absorb and isolate the mechanical noise that is to be transmitted from the air outlet 1. The combination of the protective frame 311 and the sound-absorbing cotton 312 has good sound absorption and isolation performance, which can reduce the mechanical noise transmitted through the air outlet 1.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The air outlet buffer 32 includes an air outlet pipe 321 and a sound-absorbing felt 322. The air outlet pipe 321 is located inside the protective frame 311 and is fixedly connected to the protective frame 311, with both the front and rear ends penetrating the protective frame 311. The sound-absorbing felt 322 is located inside the air outlet pipe 321 and is fixedly connected to the inner wall of the air outlet pipe 321.

[0025] The above solution is adopted: by setting up an air outlet buffer 32, the noise reduction function is used when the air is vented, so that the air is buffered through the air outlet pipe 321, and at the same time, the sound-absorbing felt 322 absorbs the wind noise caused by the impact and collision between the air and the air outlet pipe 321.

[0026] refer to Figure 2 and Figure 3 The air outlet duct 321 has a continuously curved shape.

[0027] The above solution is adopted: by setting the air outlet duct 321 as a continuous curved shape, noise will be reflected and interfered during the propagation of the noise along the continuous curved duct, which helps to consume noise energy and thus achieve the effect of noise reduction. At the same time, the continuous curved shape can buffer the wind and further consume energy, so that the air velocity is reduced after passing through the continuous curved duct, and the airflow noise is also reduced accordingly.

[0028] refer to Figure 1 and Figure 4 The mounting assembly 33 includes positioning rods 331, locking heads 332, and push springs 333. There are two positioning rods 331, which are respectively set on the upper and lower sides of the placement groove 4. The left and right ends of the two positioning rods 331 are fixedly connected to the left and right side surfaces of the placement groove 4, respectively. The locking heads 332 are sleeved on the left end surface of the two positioning rods 331 and are slidably connected to the positioning rods 331. The left end of the locking heads 332 extends into the air outlet 1 and is movably connected to the air outlet 1. There are two push springs 333, which are respectively sleeved on the surface of the two positioning rods 331. The left and right ends of the two push springs 333 are fixedly connected to the right side of the locking heads 332 and the right side surface of the placement groove 4, respectively.

[0029] The above solution involves setting up an installation component 33 to fix the protective frame 311, which facilitates the quick installation and subsequent disassembly of the protective frame 311.

[0030] refer to Figure 1 and Figure 4 The left and right sides of the guard frame 311 are provided with mating grooves 5, and the positions of the two mating grooves 5 correspond to and are compatible with the positions of the two mounting components 33.

[0031] The above solution is adopted: by providing mating grooves 5 on both the left and right sides of the guard frame 311, which are used to engage with the mounting component 33, thereby achieving quick fixation of the guard frame 311 during installation.

[0032] refer to Figure 1 and Figure 4 A pull button 6 is fixedly connected to the front surface of the lock head 332. The front end of the pull button 6 extends into a placement groove 4 and is movably connected to the placement groove 4.

[0033] The above solution is adopted: a pull button 6 is fixedly connected to the front surface of the lock head 332 to pull the lock head 332, so as to facilitate the release of the lock head 332 from the guard frame 311.

[0034] The working principle of this utility model:

[0035] During use, the mechanical noise to be transmitted from the air outlet 1 is blocked by the protective frame 311, and at the same time, the sound-absorbing cotton 312 absorbs the noise, isolating and reducing the transmission of noise. The air is discharged through several air outlet pipes 321. At the same time, the air outlet pipes 321 and the sound-absorbing felt 322 work together to buffer the wind noise brought by the impact of the air on the air outlet pipes 321. The continuous bending of the air outlet pipes 321 will cause the noise to reflect and interfere during the propagation process, which helps to consume the noise energy and thus achieve the effect of noise reduction. At the same time, the continuous bending of the air outlet pipes 321 can buffer the air and further consume energy, so that the air velocity is reduced after passing through the continuous bending of the air outlet pipes 321, and the airflow noise is also reduced. During installation, press the protective frame 311 into the air outlet 1 from front to back. When the protective frame 311 presses against the two lock heads 332, the lock heads 332 are pressed against the surface of the positioning rod 331 and move into the placement groove 4. At the same time, the push spring 333 is pressed. After the protective frame 311 is fully pressed into the air outlet 1, the two docking grooves 5 will correspond to the two lock heads 332. At this time, the lock heads 332 are no longer pressed, and the push spring 333 will rebound and push the lock heads 332 into the docking grooves 5 on the surface of the positioning rod 331, thus completing the installation. When disassembling, pull the button 6 to the left and right. The button 6 will drive the lock heads 332 to move into the placement groove 4 on the surface of the positioning rod 331, so that the lock heads 332 move out of the docking grooves 5, releasing the fixation of the protective frame 311. Then the protective frame 311 can be taken out from the air outlet 1.

[0036] In summary, this noise-reducing air conditioner outlet, through the coordinated use of an air outlet 1, a duct body 2, a noise reduction device 3, a protective cover 31, a protective frame 311, sound-absorbing cotton 312, an air outlet buffer 32, an air outlet pipe 321, a sound-absorbing felt 322, an installation component 33, a positioning rod 331, a lock head 332, a push spring 333, a placement groove 4, a docking groove 5, and a pull button 6, solves the problem that existing air outlets transmit a large amount of mechanical noise from inside the duct while discharging air, and cannot reduce noise. Furthermore, when the airflow from a traditional air outlet is fast and large, the air will directly collide with the air vent's flap, generating wind noise that affects the surrounding environment and causes discomfort.
