Further, in the embodiment of the present invention, the ventilator 1 may be an existing ventilator structure, for example, as shown in fig. 2 to 4, in addition to the humidifier 101, the ventilator may further include a main unit 102, a control panel 103, a display screen 104, an air inlet 105, a power supply port 106, and the like may be disposed outside the main unit 102, a blower 109 may be disposed inside the main unit 102, an operation key is disposed on the control panel 103, and includes an upper direction key, a start/stop key, a lower direction key, a left direction key, and a right direction key, the humidifier 101 may include a water tank 107 and a heating sheet 108 disposed on the main unit 102, and the water tank is provided with an air outlet connected to a pipeline. One end of the fan 107 is connected with the air inlet 105, the other end is connected with the water tank through a connecting pipe, a pressure sensor 110 and a flow sensor 111 are arranged on the connecting pipe of the fan and the water tank, and an inlet filter 112 is arranged at the air inlet 105 to filter impurities in the air. In use of the respirator, the heater plate begins to heat the water tank and the fan 109 is activated to draw external air into the main unit and then to the water tank, and steam generated by heating of the heater plate by the air flow delivered by the fan is fed to the mask through the conduit to fill the mask 3 with air.
Further, in embodiments of the present invention, the wearing of the mask by the user may be detected using existing techniques. The humidity sensor is disposed in the mask at a location that is less susceptible to humidity in the conduit, for example, at a location relatively far from the conduit and the mask, rather than at the outlet of the conduit and in the direction of the conduit flow.
In the embodiment of the present invention, the gears of the humidifier 101 may include m gears, where m is 2xAnd x is an integer of 2 or more, wherein 0 represents an off position, 1, …, and m-1 represents a gradually increasing humidification position. Preferably, x is equal to 2 or 3. In a preferred example, x may be equal to 2, such that the humidifier 101 may have 4 shift positions, where 0 is an off shift position and 1-3 are gradually increasing humidification shift positions. Humidifier baffleThe position control can be controlled by a valve. Specifically, the end part of the pipeline connected with the water tank can be provided with a valve support frame, the valve support frame can be provided with X fan-shaped valves which take the axial center of the pipeline as a connecting point, the X fan-shaped valves are sequentially connected to form a circle, namely, the X fan-shaped valves are all closed, and the pipeline is in a closed state. The area of the x valves is set as: the area of the first valve is S1, the area of the second valve is S2, the area of the xth valve is Sx, Si +1 is 2 × Si, and i takes on values from 1 to x.
Thus, when the shift position is the 4 th shift position, the area of the first valve is S1, the area of the second valve is S2, and S2 is 2 × S1. 0 corresponds to both S1 and S2 being closed; 1 corresponds to S1 open; 2 corresponds to S2 open; 3 corresponds to both S1 and S2 being open. The controller only needs to control the switches of the first valve and the second valve according to the humidity value, and the gear of the humidifier can be controlled. The specific realization of the valve adopts the prior art.
In the embodiment of the present invention, the controller 2 may be a separate control device, or may be a control chip integrated on the control chip of the ventilator 1. The preset reference temperature [ Wmin, Wmax ] stored in the controller 2 may be, for example, assumed that Wmin is 40 and Wmax is 70. Of course, may be rearranged according to the user's doctor's advice, and the present invention is not particularly limited. Furthermore, during each use by the user, the humidity queue in the controller 2 is initialized, i.e. the humidity queue value of the previous use is emptied.
Further, in the embodiment of the present invention, the controller 2 may set the initial gear of the humidifier and perform switching control of the gear of the humidifier during use, according to the humidity value detected by the humidity sensor and the reference temperature and humidity queues.
When the controller sets an initial gear based on a humidity value detected by a humidity sensor, the controller may control the gear of the humidifier according to the humidity value detected by the humidity sensor, the reference temperature, and the humidity queue, and the method may include:
s100, sampling a humidity value W0 detected by a humidity sensor at preset time intervals; in the embodiment of the invention, the preset time can be 1-10 minutes, and preferably 3-5 minutes, so as to timely control the humidity in the mask.
S110, if Q is Null and W0< Wmin, determining a gear G of the humidifier according to Wmin and W0 and not adding W0 to the humidity queue Q;
s120, if Q is Null and W0 is ≧ Wmin, then W0 is added to humidity queue Q.
Q ═ Null, which indicates that there is no detected humidity value in the humidity queue, i.e. the user has just used the ventilator. Steps S110 and S120 can set the initial range of the humidifier to a humidification range such that W0 is greater than Wmin.
The gear G of the humidifier in step S110 may be determined in two ways:
mode 1: in S110, gear
Mode 2: in S110, the gear G is determined by:
if W0<D1, then G ═ m-1; if not, then,
d1 is a preset humidity threshold, e.g., D1 ═ Wmin/4.
Mode 1 is a linear determination, and gear G can be obtained simply and quickly. Mode 2 can more easily achieve Wmin quickly with a small W0, and is highly efficient. The introduction of D1 was aimed at avoiding switching between multiple valves in the case of larger m.
In an embodiment of the present invention, when the controller switches the shift stage of the humidifier based on the humidity value detected by the humidity sensor during use, controlling the shift stage of the humidifier according to the humidity value detected by the humidity sensor and the reference temperature and humidity queue may include: s130, if W0>Wmax, and current gear GWhen in use>0, then the current gear of the humidifier is switched to gear G ═ GWhen in use1, namely, descending the first gear; executing S240;
s140, if Q is not equal to Null, if the length of the humidity queue Q is less than n, adding W0 in S130 into the humidity queue Q;
s150, if the length of the humidity queue Q is equal to n, removing Q1 from the humidity queue Q, moving Qi +1 to Qi in the humidity queue, and adding W0 in S130 to the humidity queue Q as Qn;
s160, acquiring the humidity quantity z in the humidity queue Q, wherein z is less than or equal to n;
and S170, determining whether to switch the gear of the humidifier according to the humidity values in the humidity queue Q.
Through the previous steps, the humidity value W0 detected by the humidity sensor is a humidity value within the reference humidity [ Wmin, Wmax ]. At this time, it is necessary to determine whether or not to perform shift switching according to the humidity queue Q, and for example, if the humidity in the humidity queue Q is constantly increasing, the shift needs to be lowered, and if the humidity in the humidity queue Q is constantly decreasing, the shift needs to be raised. Specifically, S170 may include:
s172, obtaining k and b, so that
S174, if k<k1, and current gear GWhen in use<m-1, then the current gear is switched to G ═ GWhen in use+1, i.e. up to one gear; finishing;
s176, if K>k2, and current gear GWhen in use>0, then the current gear is switched to G ═ GWhen in use1, namely, reducing the first gear; finishing;
s178, if k is larger than or equal to k1 and smaller than or equal to k2, the current gear is not switched, namely the current gear is not changed; and (6) ending.
Wherein k1 and k2 are preset thresholds. Preferably, k1<0, k2> 0. More preferably, k1+ k2 ═ 0 |, more preferably, | k1| ═ k2| < (Wmax-Wmin)/n. Therefore, the humidity value in the mask can be ensured not to be rapidly increased from Wmin to Wmax within preset n sampling time.
It should be noted that steps S110 and S130 may be executed sequentially or in parallel, and the present invention is not particularly limited.
To sum up, in the adaptive ventilator system provided in the embodiment of the present invention, the humidity sensor is disposed in the mask worn by the user, the controller samples the humidity value in the mask detected by the humidity sensor every predetermined time, and controls the gear of the humidifier according to the sampled humidity value, including setting of the initial gear and gear switching during use, so as to control the humidity in the mask to be in a comfortable breathing environment suitable for breathing, and user experience can be improved.
