Plate is arranged in parallel with sealing partition.
By adopting the above technical scheme, noise reduction layer can effectively eliminate the noise that atomizer generates in use, solve
Atomizer leads to the problem of noise to influence driver's health；Wherein, bloop can eliminate a part and pass through bloop
Noise so that into the sound attenuation of silencing cavity；Sealing partition can play support bloop, to form the work of silencing cavity
With, and cooperate sound gobo, enables reflection, the interference of noise sound wave generation sound in silencing cavity, a part of noise sound wave
It is cancelled, is lost, to reduce the sound energy to external radiation, the noise in a part of silencing cavity can be eliminated.
Further, the bloop that several are in honeycomb distribution is provided on the bloop.
By adopting the above technical scheme, when setting is utilized sound wave and propagates in porous sound-absorbing material or sound absorption structure in this way
The phenomenon that dissipating due to friction can convert thermal energy for sound, make gradually to decay by the noise of bloop, eliminates a part
Noise.
Further, the sound gobo is equipped with several through-holes, and the through-hole runs through along towards the direction of sealing partition
Sound gobo.
By adopting the above technical scheme, setting not only may make a part of noise sound wave enters can be because when propagating in through-hole in this way
Friction can convert thermal energy for sound and dissipate, and also may make the noise sound wave for leaving through-hole because of the pipeline section volume that passes through
Mutation causes reflection, the interference of the change of impedance and generation sound energy, so that noise is reduced, to achieve the purpose that noise reduction, noise reduction.
Further, the noise reduction layer is equipped with the first noise reduction lid in oil outlet at one end, and the noise reduction layer is in oil inlet
It is equipped with the second noise reduction lid at one end.
By adopting the above technical scheme, the first noise reduction lid and the second noise reduction lid are set, noise reduction layer can be cooperated entire silencing cavity
It is closed, noise loss is avoided to go out.
Further, the shell and noise reduction layer and the first noise reduction lid, the second noise reduction lid integrated setting.
By adopting the above technical scheme, the fastness and noise reduction layer and first that can guarantee silencing cavity space structure are set in this way
Leakproofness between noise reduction lid, the second noise reduction lid.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the sealing partition.
Fig. 3 is the structural schematic diagram of the sound gobo.
Specific embodiment
Specific embodiment of the present utility model is described further below in conjunction with accompanying drawings and embodiments.
It is as shown in Figs. 1-3 it is a kind of can noise reduction atomizer, including shell 1, magnet 11, coil 12 and and closing coil
12 terminal 13, the shell 1 is interior to be equipped with middle pipe 2, and oil outlet 14 is successively arranged in the middle pipe 2, dynamic valve 15, spring 16, is determined
Valve 17, copper pipe 18, oil inlet 19, the oil outlet 14 are equipped with valve seat plate 21 and hole piece 20, and the oil inlet 19 is equipped with strainer
22。
The shell 1 includes noise reduction layer 3, and the noise reduction layer 3 includes two layers or two layers or more of bloop 4, the noise reduction
Silencing cavity 5 is formed between piece 4 and bloop 4, is equipped with the several and vertically disposed sealing partition of bloop 4 in the silencing cavity 5
6, the sealing partition 6 is ring-type and interior edge, outer are connected with two adjacent bloops 4 respectively, between two adjacent sealing partitions 6
