Abstract
The utility model relates to a controllable domestic sleep breathing machine, relating to a scheme capable of accurately and quickly controlling the pressure of a fan air pipe of the domestic sleep breathing machine. Related devices in the scheme comprise a fan, a power supply, a controller, an inverter, a sensor and an air passage. The changes of the pressure, flow rates and electric current signals are monitored in real time through the controller, and the stable change of magnetic field vector inside the fan is controlled in a vector control manner, therefore, the dynamic response of a system is greatly improved, and the running noise is greatly reduced.
Description
Technical field
This utility model relates to a kind of scheme that can carry out fast domestic sleep-respiratory machine treatment pressure, accurately control.
Background technology
The treatment pressure of respirator is controlled by dual mode in the market.First kind is that quick switching by valve body in the gas piping realizes.This kind method is comparatively common in large-scale medical breathing machine, but is not having to be difficult for realization on the domestic sleep-respiratory machine of air compressor machine, and the cost height.Second method is to adopt the rotating speed of voltage trapezoidal wave control blower fan to respond.But adopt the meeting of voltage trapezoidal wave control to bring the blower fan torque not steady, noise is big, the problem of dynamic response difference.
The utility model content
The purpose of this utility model adopts the mode of vector controlled to realize the pressure control of domestic sleep-respiratory machine.Make treatment pressure can respond the variation of human body respiration fast and accurately.Thereby improve the level of comfort of user, also reduced noise simultaneously.
The technical scheme that this utility model adopted is: a controllable type domestic sleep-respiratory machine, adopt small sized turbine formula blower fan, fan outlet links to each other with the user nasal mask with connecting line by flow transducer, the while nasal mask is drawn an airway and is connected on the pressure transducer of panel, again by being connected to the power line of blower fan after the inversion, the while also feeds back to controller with the power line of blower fan to dc source by controller.
The beneficial effects of the utility model mainly show: realize the rotating speed control up to 40000 revolution per seconds of sleep-respiratory machine blower fan, realized starting and rotating speed control in 0.1 second.Make the running noises of sleep-respiratory machine reduce greatly simultaneously.
Description of drawings
Fig. 1 is the sleep-respiratory machine control sketch map of the embodiment of the invention.
The specific embodiment
Below in conjunction with accompanying drawing this utility model embodiment is further described.
As shown in Figure 1, the pressure flow closed loop control outer shroud formed of the vector controlled internal ring be made up of controller-inverter-blower fan of whole sleep-respiratory machine control system and controller-gas piping is formed.Outer shroud is gathered in the gas piping by controller in real time because the pressure that the human body respiration motion causes and the variation of flow are calculated by controller, and the variation of pressure and flow is converted into closed loop control to rotation speed of fan.Internal ring calculates by controller by the electric current of controller real-time sampling blower fan, is converted into the driving control to inverter, and then influences the electric current of blower fan again, and so constantly Automatic Cycle realizes the steady control to blower fan internal magnetic field vector.Because the torque of blower fan is all directly relevant with the steady degree of internal magnetic field vector with noise, thereby the method has reached the purpose that improves the system dynamics response and reduce running noises.
Above described only be that this utility model preferred implementation is described; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from this utility model design philosophy; common engineers and technicians all should belong to protection domain of the present utility model as controller type in the technical solution of the utility model and sensor type are changed in this area.
