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, as snoring can cause the raising of the understanding of various disease, in family care, often respirator can be used.But, because respirator all can use blower fan to manufacture compressed air to supply patient respiratory, in the compressed-air actuated process of manufacture, run up the vibrations noise and aerodynamic noise that can produce and make us unhappy of turbofan, this can have a strong impact on the sleep quality of patient.
Summary of the invention
Technical problem to be solved by this invention is, provides a kind of safe and reliable, breathing machine pipeline denoising structure that noise is little.
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 fan body and compressed air delivery outlet, described 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 air circulation room, described air circulation room comprises the upper-deck cabin being positioned at described blower fan top and the lower cabin being 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, the surrounding of described sealed compartment is provided with one for the through hole through described compressed air delivery outlet.
Described 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 piece of flat board arranged in parallel, the setting direction of described shunting partition panel is air throughput direction, corner in described upper-deck cabin and/or lower cabin and horizontal direction are that 15 ~ 75 ° of angles are placed, 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.
The silicagel pad for damping is provided with between described compressed air delivery outlet and through hole.
Described sealed compartment inwall is provided with the some grids for guiding air throughput direction, described grid is the slab organization be 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 the aerodynamic noise of the generation of blower fan high speed rotating, the method lowering aerodynamic noise is pressure everywhere in equilibrium air transfer pipeline mainly, the sudden change of caliber size in air delivery pipe is eliminated in design, namely air delivery pipe comprises upper-deck cabin, the ventilative soft layer in lower cabin and connection upper-deck cabin and lower cabin, because fan body and sealed compartment are the design of cylinder or Elliptic Cylinder, therefore upper-deck cabin and lower cabin are circle, just eliminate the sudden change of caliber size in air delivery pipe, in addition, to the place that may produce air-swirl in air delivery pipe, picture turning, upper-deck cabin carries the corner of air and ventilative soft layer to carry the corner etc. of air to horizontal direction to ventilative soft layer, then adopt and seamlessly transit and the middle measure increasing shunting partition panel around the corner, avoid the aerodynamic noise because air-swirl causes, a measure is also had to be extend air inlet approach, air inlet is extended to the spacing of turbofan air inlet, can avoid producing air at fan air inlet place like this and kick flow noise, method is that the first air-in is arranged on sealed compartment top, second air-in is arranged on blower fan bottom, after air is entered by the first air-in, successively by entering the second air-in behind upper-deck cabin, ventilative soft layer and lower cabin, extend air fed distance.Lower the method for the vibration noise that blower fan high speed rotating produces for blower fan is arranged in sealed compartment, the ventilative soft layer of blower fan surrounding closely wraps up doing damping, in addition, the silicagel pad for damping is again provided with between the compressed air delivery outlet of blower fan and the through hole of sealed compartment, this kind of design sound insulation and weakening effective, effectively reduce vibration noise.A kind of breathing machine pipeline denoising structure provided by the invention, reasonable in design, structure is simple, and cost is low, safe and reliable, effectively reduces the noise of respirator, ensures that patient easily falls asleep, improves sleep quality and the quality of life of patient.
