Abstract
The utility model provides a fan housing of making an uproar falls in breathing machine which characterized in that: including the holder, the top of holder is provided with the vent, and evenly distributed has a plurality of hole grooves on the inner wall of holder, and the inner wall bottom of holder is provided with many rings shape rib that distributes with spiral case air intake handing-over department, all paste on the cell wall of hole groove and on the rib and inhale the sound cotton. The utility model discloses the holder that uses area air inlet and ventilation window covers on the spiral case air intake to inhale the sound cotton and absorb the noise in holder and spiral case air intake handing-over department installation, whole device has also reached when having ensured air inlet efficiency and has inhaled the sound and fall the purpose of making an uproar, because device simple structure, the overall structure to the fan influences not greatly moreover, and it is all very convenient to install and maintain.
Description
Technical Field
The utility model relates to a breathing machine accessory field, concretely relates to fan housing of making an uproar falls in breathing machine.
Background
A ventilator, which is a device having an artificial ventilation function, is widely used for treating diseases such as respiratory failure and sleep apnea hypopnea syndrome due to various causes, and occupies a very important position in the modern medical field. In the field of noninvasive ventilators, with the attention of people on respiratory therapy, the performance requirements on ventilators are higher, wherein two indexes which are easily perceived by users are radiation noise and conduction noise respectively. The two indexes directly influence whether the user can fall asleep or not, and particularly can be used as a judgment basis for judging whether the user is willing to accept noninvasive and non-respiratory therapy for a long time or not when the user just uses the device.
The noise source of the noninvasive ventilator is mainly a blower device, and in order to solve the problems in the prior art, a device capable of reducing the noise of the blower is urgently needed.
Disclosure of Invention
The utility model aims at overcoming prior art's shortcoming and not enough, providing a fan housing of making an uproar falls in breathing machine that simple structure, noise reduction effect are good.
In order to achieve the above purpose, the technical solution of the utility model is that: the utility model provides a fan housing of making an uproar falls in breathing machine which characterized in that: the novel spiral casing air inlet device is characterized by comprising a retainer, wherein a vent is arranged at the top of the retainer, a plurality of hole grooves are uniformly distributed in the inner wall of the retainer, a plurality of ribs distributed in an annular mode are arranged at the joint of the bottom of the inner wall of the retainer and a spiral casing air inlet, and sound absorbing cotton is attached to the groove wall of each hole groove and the ribs.
The bottom of the outer wall of the retainer is provided with a plurality of fixed supports, and the fixed supports are provided with mounting and fixing holes.
The diameter of the vent is smaller than that of the volute air inlet.
The utility model discloses use the holder cover of band-pass wind gap and hole groove on the spiral case air intake to inhale the sound cotton and absorb the noise in holder and spiral case air intake handing-over department and hole inslot installation, whole device has also reached when having ensured air inlet efficiency and has inhaled the sound and fall the purpose of making an uproar, because device simple structure influences the overall structure of fan not greatly moreover, and the installation is all very convenient with the maintenance.
Drawings
Fig. 1 is a schematic view of the external structure of the present invention.
Fig. 2 is a schematic diagram of the internal structure of the present invention.
Fig. 3 is a schematic view of the installation structure of the present invention.
In the figure: the sound-absorbing cotton comprises a retainer 1, sound-absorbing cotton 2, a ventilation opening 3, a hole groove 4, ribs 5, a fixed support 6 and a mounting and fixing hole 7.
Detailed Description
The present invention will be described in further detail with reference to the following description and embodiments in conjunction with the accompanying drawings.
Referring to fig. 1-2, a fan housing of making an uproar falls in breathing machine, includes holder 1 and inhales sound cotton 2, the top of holder is provided with vent 3, the diameter of vent 3 is less than the diameter of spiral case air intake, and evenly distributed has a plurality of hole grooves 4 on the inner wall of holder 1, and the outer wall bottom of holder 1 is provided with a plurality of fixing support 6, be provided with installation fixed orifices 7 on the fixing support 6, the inner wall bottom of holder 1 is provided with many ribs 5 that form the annular distribution with spiral case air intake handing-over department, all paste on the cell wall of hole groove 4 and on the rib 5 and have inhaled sound cotton 2.
When the fan volute is manufactured, 3 bosses which are uniformly distributed and provided with small holes of 1.6mm are arranged on the periphery of the volute air inlet, and when the fan cover is manufactured, the sound-absorbing cotton 2 is twisted into cotton strips which are adhered to the ribs 5 and the groove wall of the hole groove 4 by environment-friendly glue. During installation, the installation fixing holes 7 on the retainer 1 are installed on the boss, the fan cover is fixed by screws penetrating through the small holes on the boss, and the state after installation is shown in fig. 3.
