For addressing the above problem, first aspect of the present utility model provides a kind of air quantity controller that is used to not have blade fan, and this air quantity controller comprises:
Temperature transducer, this temperature sensor monitors ambient temperature;
Control module, this control module links to each other with described temperature transducer, and produces a control signal according to the ambient temperature that described temperature sensor monitors arrives;
The pulse generation module, this pulse generation module receives described control signal, and generates a pulse, and this pulse is used to control the air quantity of described no blade fan.
In a preferred embodiment, this temperature transducer is thermistor or infrared temperature sensor.
In a preferred embodiment, described pulse is a square wave.
In a preferred embodiment, described pulse is sinusoidal wave.
According to second aspect of the present utility model, a kind of base that is used to not have blade fan is provided, this base comprises above-mentioned air quantity controller.
In a preferred embodiment, described base also comprises a fan electromotor, and this fan electromotor links to each other with described air quantity controller.
In a preferred embodiment, described fan electromotor is single-phase asynchronous motor, polyphase induction machine or synchronous motor.
According to the third aspect of the present utility model, a kind of no blade fan is provided, this no blade fan comprises above-mentioned base.
In a preferred embodiment, described no blade fan also comprises a fan fan head, and this fan fan head links to each other with described base.
According to the embodiment of air quantity controller of the present utility model, can regulate the air quantity of fan automatically, need not manual tune.Therefore, the utility model has been simplified the operation to fan, helps to control air quantity automatically according to ambient temperature under the situation of manual tune is carried out in user's inconvenience.
Description of drawings
By hereinafter in conjunction with the accompanying drawings detailed description, will understand the utility model better.Should be understood that these accompanying drawings only for illustrative purposes, and may not draw in proportion.In the accompanying drawings:
Fig. 1 is the plan view according to the no blade fan of an embodiment of the present utility model.
Fig. 2 is the detailed view according to the connection of each parts in the base of an embodiment of the present utility model.
Fig. 3 is the no blade fan air quantity control flow schematic representation according to an embodiment of the present utility model.
Embodiment
Fig. 1 is the plan view according to the no blade fan 1 of an embodiment of the present utility model.Shown in this Fig. 1, this no blade fan 1 comprises base 2 and fan fan 3.Base 2 and fan fan 3 is connected by screw, but should be understood that base 2 and fan fan 3 and also can be connected by other modes.Include fan electromotor 4 and air quantity controller 5 in the base 2, fan electromotor 4 links to each other with air quantity controller 5.Air quantity controller 5 comprises temperature transducer 6, control module 7 and pulse generation module 8, will descend among Fig. 2 and will describe air quantity controller 5 in detail.Fan electromotor 4 can be single-phase asynchronous motor, polyphase induction machine, synchronous motor etc., and temperature transducer 6 can be thermistor, infrared temperature sensor etc., but should be understood that the type of fan electromotor and temperature transducer is not limited to described herein.
Fig. 2 is the detailed view according to the connection of each parts in the base 2 of an embodiment of the present utility model.As shown in Figure 2, temperature transducer 6 is connected to control module 7, and control module 7 paired pulses generation modules 8 are controlled.Pulse generation module 8 receives control signal from control module 7, and responds the different pulse of this control signal generation dutycycle, thereby regulates the rotating speed of fan electromotor 4, and then regulates air quantity.
Fig. 3 is the no blade fan air quantity control flow schematic representation according to an embodiment of the present utility model.As shown in Figure 3, in step 301, temperature transducer 6 monitoring of environmental temperature are also transmitted the signal of a relevant ambient temperature to control module 7.In step 302, the signal of this relevant ambient temperature that control module 7 storage temperature sensors 6 transmit, and last signal that itself and control module before 7 are preserved compares, and according to comparative result, control module 7 is sent a control signal to pulse generation module 8.In step 303, pulse generation module 8 generates a pulse signal according to the control signal that receives, the rotating speed of this pulse signal control fan.
Particularly, temperature transducer 6 is in t1 monitoring of environmental temperature T 1 constantly, and will represent that the signal S1 of environment temperature T 1 is passed to control module 7.Then, temperature transducer 6 is in next t2 monitoring of environmental temperature T 2 constantly, and will represent that the signal S2 of environment temperature T 2 is passed to control module 7.Time difference Δ t between t1 and the t2 can be (for example 10 minutes, 15 minutes etc.) fixed, also can be unfixed.Control module 7 compares signal S1 and S2.Judge in t2 temperature T 2 constantly that when control module 7 control module 7 produces control signal C1 during greater than constantly temperature T 1 of t1, this control signal C1 configuration pulse generation module 8 makes pulse generation module 8 generate the pulse that dutycycle is D1; When control module 7 is judged in t2 temperature T 2 constantly during less than constantly temperature T 1 of t1, control module 7 produces control signal C2, this control signal C2 configuration pulse generation module 8, make pulse generation module 8 generate the pulse that dutycycle is D2, when control module 7 is judged when t2 temperature T 2 constantly equals the temperature T 1 in the t1 moment, control module 7 produces control signal C3, and this control signal C3 configuration pulse generation module 8 makes pulse generation module 8 generate the pulse that dutycycle is D3.The pulse that pulse generation module 8 generates can be a square wave, also can be sinusoidal wave, the rotating speed of this pulse control fan electromotor 4, when duty of ratio was big, the rotating speed of fan electromotor 4 was fast, and air quantity is big, when duty of ratio hour, the rotating speed of fan electromotor 4 is slow, and air quantity is little.In the pulse that above-mentioned pulse generation module 8 generates, the pass of D1, D2 and D3 is D1＞D3＞D2.Next, with the t3 of t2 Δ blanking time t constantly, temperature transducer 6 is monitoring of environmental temperature T 3 once more, 7 couples of T3 of control module and T2 compare, and repeat step as above.
Should be understood that these embodiments only for illustrative purposes, those skilled in the art can make many variants, and scope of the present utility model is defined by the claims.
