Technical Field
[0001] The utility model relates to the technical field of air conditioning, in particular to an air conditioning muffler valve. Background Art
[0002] With the advancement of science and technology and the development of society, air conditioning equipment has become an indispensable part of modern life, providing people with a comfortable environment. The air conditioning silencer valve is a valve installed in the air conditioning system. Its main function is to reduce the noise generated when the air conditioning system is running.
[0003] In the prior art, when the air conditioning equipment is in operation, the air intake pipe of the air conditioning generally adopts a direct exhaust method when taking in air. When the direct exhaust air impacts the inside of the pipe, the continuous impact sound affects people's life and work. Therefore, in response to the above problem, we propose a new type of air conditioning silencer valve. Utility Model Content
[0004] The purpose of the utility model is to solve the problem in the prior art that the existing air intake pipe of the air conditioner generally adopts a direct discharge method when taking in air, and when the direct discharged air impacts the inside of the pipe, the continuous impact sound affects people's life and work, and an air conditioning silencer valve is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an air-conditioning silencer valve, comprising an outer shell, a fixing rod is arranged inside the outer shell, two ends of the fixing rod are in the same horizontal plane with two ends of the outer shell, a spiral channel is fixedly connected to the outer surface of the fixing rod, the outer surface of the spiral channel is fixedly connected to the inner surface wall of the outer shell, silencer cotton is fixedly connected to the outer surfaces of both sides of the spiral channel, an air inlet pipe is fixedly connected to the top of the outer shell, and an air outlet pipe is fixedly connected to the bottom of the outer shell.
[0006] Preferably, the spiral pitch of the spiral channel decreases downwards, and the spiral channel cooperates with the upper part of the shell to form a first resistive muffler chamber.
[0007] Preferably, the spiral channel cooperates with the middle part of the shell to form a second resistive silencing chamber, and the spiral channel cooperates with the lower half of the shell to form a third resistive silencing chamber.
[0008] Preferably, the top end of the air inlet pipe is fixedly connected to a first flange, and the bottom end of the air outlet pipe is fixedly connected to a second flange.
[0009] Preferably, a filter screen is provided at the inner bottom of the shell.
[0010] Preferably, the air intake pipe is in an hourglass shape, and a first drag reduction channel is provided between inner surface walls of the air intake pipe.
[0011] Preferably, the outlet pipe is in an hourglass shape, and a second drag reduction channel is provided between the inner surface walls of the outlet pipe.
[0012] 1. In the utility model, when in use, the silencer valve is connected to the air-conditioning equipment through the air inlet pipe and the air outlet pipe. When the air-conditioning equipment is working, the generated airflow first enters the interior of the shell through the first resistance reduction channel, and the spiral spiral channel can effectively disperse and weaken the energy of the noise sound wave, and then through the sound-absorbing cotton, the energy of the sound wave is dispersed and weakened again, and the density of the spiral channel decreases downward in sequence, forming a first resistive sound-absorbing chamber, a second resistive sound-absorbing chamber and a third resistive sound-absorbing chamber, so the path of sound wave propagation in the spiral channel is more complicated and tortuous, which can make the sound wave more reflected, refracted and interfered during the propagation process, so as to further consume the noise sound energy and enhance the sound-absorbing effect, thereby avoiding the problem that the impact sound continuously generated when the straight-discharged air impacts the inside of the pipe affects people's life and work.
[0013] 2. In the utility model, when air flows through, the hourglass-shaped air inlet and outlet pipes facilitate smoother air flow, reduce the strong impact and turbulence caused by the sudden change of direction of the air flow, and thus reduce the noise generated by the impact of the air flow.

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0021] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides an air conditioning silencer valve, including an outer shell 1, a fixing rod 4 is arranged inside the outer shell 1, two ends of the fixing rod 4 are in the same horizontal plane with the two ends of the outer shell 1, a spiral channel 41 is fixedly connected to the outer surface of the fixing rod 4, the outer surface of the spiral channel 41 is fixedly connected to the inner surface wall of the outer shell 1, and silencer cotton 42 is fixedly connected to the outer surfaces of both sides of the spiral channel 41, an air inlet pipe 2 is fixedly connected to the top of the outer shell 1, an air outlet pipe 3 is fixedly connected to the bottom of the outer shell 1, the pitch of the spiral channel 41 decreases downward in sequence, the spiral channel 41 cooperates with the upper half of the outer shell 1 to form a first resistive silencer chamber 5, the spiral channel 41 cooperates with the middle part of the outer shell 1 to form a second resistive silencer chamber 51, and the spiral channel 41 cooperates with the lower half of the outer shell 1 to form a third resistive silencer chamber 52, the top end of the air inlet pipe 2 is fixedly connected to the first flange 22, the bottom end of the air outlet pipe 3 is fixedly connected to the second flange 32, and a filter screen 11 is arranged at the inner bottom of the outer shell 1.
[0022] The effect achieved by the entire embodiment 1 is that, when in use, the silencer valve is connected to the air-conditioning equipment through the air inlet pipe 2 and the air outlet pipe 3. At this time, when the air-conditioning equipment is working, the generated airflow will first enter through the first resistance reduction channel 21, and then enter the interior of the shell 1. When the sound waves of the noise propagate in the spiral channel 41, since the spiral channel 41 is spiral, the shape change of the channel will effectively disperse and weaken the energy of the noise sound waves, and the outer surfaces of both sides of the spiral channel 41 are connected with silencer cotton 42. At this time, the energy of the noise sound waves will be dispersed and weakened again, and the density of the spiral channel 41 decreases downward in sequence, so that the spiral channel 41, in cooperation with the shell 1, forms a first resistive silencer chamber 5, a second resistive silencer chamber 51 and The third resistive silencing chamber 52, so when the density of the spiral channel 41 gradually increases, it means that the path of sound waves propagating in the spiral channel 41 is more complicated and tortuous, and this complex path can cause more reflections, refractions and interferences of sound waves during the propagation process, thereby further consuming noise energy and enhancing the silencing effect, avoiding the problem of continuous impact sound when the straight-discharged air impacts the inside of the pipe, affecting people's life and work. Finally, the noise that has been processed three times is discharged from the second drag reduction channel 31, the first flange 22 and the second flange 32 are respectively used for the connection sealing between the air inlet pipe 2 and the air outlet pipe 3 and the air-conditioning equipment, the filter screen 11 improves the cleanliness of the airflow, and the fixing rod 4 is used to enhance the stability of the spiral channel 41.
[0023] Embodiment 2, as Figure 1-Figure 4 As shown, the shape of the air intake pipe 2 is hourglass-shaped, and a first drag reduction channel 21 is arranged between the inner walls of the air intake pipe 2; the shape of the air outlet pipe 3 is hourglass-shaped, and a second drag reduction channel 31 is arranged between the inner walls of the air outlet pipe 3.
[0024] The effect achieved by the entire embodiment 2 is that when the air flows through, the hourglass-shaped air inlet pipe 2 and the air outlet pipe 3 facilitate the air flow to pass more smoothly, reduce the strong impact and turbulence caused by the sudden change of direction of the air flow, and thus reduce the noise generated by the impact of the air flow.
[0025] Working principle: When in use, the silencer valve is connected to the air conditioning equipment through the air inlet pipe 2 and the air outlet pipe 3. When the air conditioning equipment is working, the generated airflow will first enter the interior of the shell 1 through the first resistance reduction channel 21. The spiral spiral channel 41 will effectively disperse and weaken the energy of the noise sound wave, and then pass through the silencer cotton 42 to disperse and weaken the energy of the sound wave again. The density of the spiral channel 41 decreases downward in sequence, forming a first resistive silencer chamber 5, a second resistive silencer chamber 51 and a third resistive silencer chamber 52. Therefore, the path of sound wave propagation in the spiral channel 41 is more complex and tortuous, so that the sound wave can be reflected, refracted and interfered more during the propagation process, thereby further consuming the noise sound energy and enhancing the silencing effect. It avoids the problem that the continuous impact sound generated when the straight-discharged air impacts the inside of the pipe affects people's lives and work. In addition, when the air flows through, the hourglass-shaped air inlet pipe 2 and the air outlet pipe 3 are conducive to smoother passage of the airflow, reducing the strong impact and turbulence caused by the sudden change of direction of the airflow, thereby reducing the noise generated by the impact of the airflow.
[0026] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
