And (3) testing: noise detection test

Test samples: examples 1 to 5 were selected as test samples 1 to 5, and comparative examples 1 to 4 were selected as control samples 1 to 4.

The test method comprises the following steps: starting the test samples 1-5 and the control samples 1-4 in a quiet environment, detecting the noise of the test samples 1-5 and the control samples 1-4 by using a Teishi (TES) TES-52AA portable decibel instrument, recording and comparing for analysis.

And (3) test results: the decibel profiles generated during operation for test samples 1-5 and control samples 1-4 are shown in Table 1.

As can be seen from table 1, the noise of the test samples 1 to 5 was low and hardly heard in a quiet environment, which makes the user feel comfortable. However, the noise of the control samples 1 to 6 is higher than that of the test samples 1 to 5, and is more obvious in a quiet environment, and the user is disturbed to rest to different degrees during use.

The above problem of the comparison sample 1 is mainly caused by that the connection pipe, the rubber ring and the clamping ring are removed together in the comparison sample 1, so that the connection between the internal structures of the comparison sample 1 is not tight enough, and therefore, the phenomenon of excessive noise is easily caused.

The above problems occurred in the comparison samples 2-4, mainly because the rubber ring and the clamping ring were not present in the comparison samples 2-4 to different extents, thereby resulting in loosening of the internal structure of the comparison samples 2-4 to different extents and easy leakage of noise from the inside of the atomizer.

The above problem occurs in the control 5, mainly because the material of the connecting portion is different, which affects the noise generated during the air injection process of the air pump.

The above problem occurs in the comparison sample 6, mainly because the atomization structure body and the insertion part for atomization and diffusion are formed by splicing in the comparison sample 6, which easily causes the phenomenon of large noise due to poor sealing effect in the operation process of the comparison sample 5.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
