Description

Technical Field

[0001] The utility model relates to the technical field of diffusing devices, in particular to a diffusing device with a noise reduction function. Background Art

[0002] A diffuser can atomize essential oil liquid into gas, which diffuses in the indoor space to form a unique fragrance environment, providing a comfortable environment for users and being widely loved by people.

[0003] However, the noise problem of diffusers has existed for a long time and has a great impact on users. The noise problem mainly includes two parts of noise. One part is the noise of the air pump, and the other part is the noise generated by the high-speed gas atomizing the mist.

[0004] A diffuser usually consists of an air pump and an atomizing head as the core mechanism. The air pump is generally arranged in the box body. The noise generated by the air pump can generally be reduced by covering it with shock-absorbing rubber and flexible materials, and the overall control effect is relatively good.

[0005] The atomizing noise is usually ignored by designers. When the atomized gas of essential oil flows out through the atomizing port, the high-speed air flow collides with the pipe wall, generating a lot of low-frequency noise, which greatly affects the use.

[0006] Therefore, how to reduce the atomizing noise is particularly important for the noise control of diffusers. Summary of the Invention

[0007] The purpose of the utility model is to provide a diffusing device with a noise reduction function that has low noise and is easy to install and maintain, so as to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the utility model provides the following technical solutions:

[0009] A diffusing device with a noise reduction function,

[0010] including an atomizing head, an atomizing channel and an atomizing port. The atomized air atomized by the atomizing head diffuses from the atomizing port through the atomizing channel.

[0011] The atomizing channel is provided with a sieve tube and a guide tube. One end of the sieve tube is provided with an air inlet, and the other end is closed. The pipe wall of the sieve tube is provided with air outlet holes.

[0012] The guide tube is sleeved outside the sieve tube, and the inner wall of the guide tube and the outer wall of the sieve tube form an atomizing gap; a plurality of sound insulation fins are arranged in the atomizing gap.

[0013] The upper end of the guide tube is communicated with the atomizing port.

[0014] Among them, the air outlet holes are disorderly distributed on the pipe wall of the sieve tube.

[0015] Wherein, the air outlet holes are staggeredly distributed from top to bottom.

[0016] Wherein, the sound insulation fin is arranged as a partition, one end of the partition is suspended in the mist outlet gap, and the other end is fixed.

[0017] Wherein, the partition is fixed to the inner wall of the air duct and / or the outer wall of the sieve tube.

[0018] Among them, multiple partitions are staggeredly distributed.

[0019] Wherein, the atomizing head is provided with an atomizing chamber, the upper end of the atomizing chamber is provided with an outlet, and the outlet is connected and communicated with the threaded pair of the air inlet end of the air guide tube.

[0020] Wherein, the screening tube is connected to the internal thread pair of the air inlet end of the air guide pipe and is in conduction.

[0021] The mist outlet is arranged on the upper cover, and the upper cover is also provided with an air intake duct, and the air intake duct is connected and communicated with the threaded pair of the air outlet end of the air guide pipe.

[0022] The aroma diffusion device is provided with an upper cover, an air inlet duct, an air guide pipe, a screening pipe and an atomization chamber in sequence from top to bottom.

[0023] Beneficial effects of the utility model:

[0024] The mist outlet channel composed of the sieve tube and the air guide tube connects the atomizer head and the mist outlet. The essential oil atomized gas generated by the atomizer head passes through the sieve tube and then enters the mist outlet gap formed by the sieve tube and the air guide tube.

[0025] The upper end of the screening tube is closed to reduce the flow rate of the atomized gas. Large-particle atomized particles agglomerate and fall back into the essential oil bottle due to gravity. Suitable small-particle atomized particles flow out through the air outlet holes on the tube wall of the screening tube. The particle screening is reliable and has high uniformity. The atomized gas flowing out of the screening tube passes through the fins in the mist outlet gap to further reduce the flow rate, reduce the collision with the tube wall, and reduce noise.

[0040] The upper end of the air guide pipe 5 is communicated with the mist outlet 3.

[0041] The air outlet holes 6 are disorderly distributed on the pipe wall of the sieve pipe 4.

[0042] The air outlet holes 6 distributed in the above manner can effectively ensure that the atomized essential oil gas is discharged through the air outlet holes 6, and the staggered air flow is beneficial to screening suitable atomized particles.
