Description
Technical field
The present invention relates to a kind of breathing machine pipeline denoising structure, belong to medical instruments field.
Background technology
At present, along with people are to hypopnea, the raising of the understanding that can cause various diseases as snored often can be used respirator in family care.But, because respirator all can be used blower fan and manufactures compressed air and supply with patient respiratory, in the compressed-air actuated process of manufacture, running up of turbofan can generation be made us unhappy vibrations noise and aerodynamic noise, and this can have a strong impact on patient's sleep quality.
Summary of the invention
Technical problem to be solved by this invention is, a kind of safe and reliable, breathing machine pipeline denoising structure that noise is little is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of breathing machine pipeline denoising structure, comprise blower fan, it is characterized in that: described blower fan comprises blower fan body and compressed air delivery outlet, described blower fan body surrounding is closely enclosed with ventilative soft layer, described ventilative soft layer is outside equipped with sealed compartment, described sealed compartment surrounding and described ventilative soft layer close contact, described sealed compartment upper and lower is provided with circulation of air chamber, described circulation of air chamber comprises the upper-deck cabin that is positioned at described blower fan top and the lower cabin that is positioned at described blower fan bottom, described sealed compartment top is provided with the first air-in, described blower fan bottom is provided with the second air-in, in the surrounding of described sealed compartment, be provided with one for the through hole through described compressed air delivery outlet.
Described blower fan body and sealed compartment are cylinder or Elliptic Cylinder.
The corner in described upper-deck cabin and/or lower cabin is provided with the shunting partition panel for avoiding producing air-swirl, described shunting partition panel is 1 ~ 4 flat board being arranged in parallel, the setting party of described shunting partition panel is to being air throughput direction, corner and horizontal direction in described upper-deck cabin and/or lower cabin are 15 ~ 75 ° of angles placements, and the height of described shunting partition panel is identical with the height in described upper-deck cabin or lower cabin.
Described blower fan is turbofan.
The material of described ventilative soft layer is high strength sponge.
Between described compressed air delivery outlet and through hole, be provided with the silicagel pad for damping.
On described sealed compartment inwall, be provided with the some grids for guiding air throughput direction, described grid is the slab organization being obliquely installed towards air throughput direction, and the length of described slab organization is 2 ~ 5cm.
A kind of breathing machine pipeline denoising structure provided by the invention, can lower vibration noise and aerodynamic noise that blower fan high speed rotating produces, lower the method for aerodynamic noise and be mainly pressure everywhere in balance air delivery pipe road, in design, eliminated the sudden change of caliber size in air delivery pipe road, be that air delivery pipe road comprises upper-deck cabin, the ventilative soft layer in lower cabin and connection upper-deck cabin and lower cabin, because blower fan body and sealed compartment are the design of cylinder or Elliptic Cylinder, therefore upper-deck cabin and lower cabin are circle, just eliminated the sudden change of caliber size in air delivery pipe road, in addition, to producing the place of air-swirl in air delivery pipe road, picture turning, upper-deck cabin carries the corner of air and ventilative soft layer to horizontal direction, to carry the corner etc. of air to ventilative soft layer, adopt and seamlessly transit and the middle measure that increases shunting partition panel around the corner, avoid the aerodynamic noise causing due to air-swirl, also having a measure is to extend air inlet approach, air inlet is extended to distance between turbofan air inlet, can avoid like this producing at fan air inlet place air and kick flow noise, method is that the first air-in is arranged on sealed compartment top, the second air-in is arranged on blower fan bottom, after air is entered by the first air-in, by entering the second air-in behind upper-deck cabin, ventilative soft layer and lower cabin, extended air fed distance successively.The method of the vibration noise that attenuating blower fan high speed rotating produces is for to be arranged on blower fan in sealed compartment, blower fan surrounding is closely wrapped up to do damping with ventilative soft layer, in addition, between the compressed air delivery outlet of blower fan and the through hole of sealed compartment, be provided with for the silicagel pad of damping again, this kind designs the effective of sound insulation and weakening, effectively reduces vibration noise.A kind of breathing machine pipeline denoising structure provided by the invention, reasonable in design, simple in structure, cost is low, safe and reliable, effectively reduces the noise of respirator, guarantees that patient easily falls asleep, and has improved patient's sleep quality and quality of life.
