This utility model is produced beneficial effect compared with background technology:
1, wind pressure detection device is used due to this utility model, the blast parameter that controller obtains in real time for processing wind pressure detection device and the rotating speed controlling motor, wind pressure detection device is for detecting the blast in cigarette machine wind cabinet, the structure that wind pressure detection device and controller electrically connect, therefore it can be effectively according to the change of blast in common flue, adjust the rotating speed of motor in real time, and then promote smoke discharging effect.
Accompanying drawing illustrates: Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that blast Sampling Interface 31 is arranged on spiral case.
Fig. 3 is the structural representation that blast Sampling Interface 31 is arranged on check (non-return) valve.
Detailed description of the invention: referring to shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, the present embodiment includes motor 1, controller 2, wind pressure detection device 3, motor 1 electrically connects with controller 2, the blast parameter that controller 2 obtains in real time for processing wind pressure detection device 3 and the rotating speed controlling motor 1, wind pressure detection device 3 is for detecting the blast in common flue, and wind pressure detection device 3 electrically connects with controller 2.
Wind pressure detection device 3 can include blast Sampling Interface 31 and wind pressure sensor 32, and blast Sampling Interface 31 can be connected with wind pressure sensor 32 by pressure tube 33.
On the wall of the spiral case that blast Sampling Interface 31 may be installed range hood, blast Sampling Interface 31 also may be installed on the air outlet check (non-return) valve of range hood, detects cigarette machine by wind pressure sensor 32 and uses the real-time blast of common flue in environment.
Wind pressure sensor 32 is electrically connected with controller 2 by holding wire, and the real-time pressure signal of common flue is transferred to controller 2 by wind pressure sensor 32, and controller 2, according to the change of blast in common flue, adjusts the rotating speed of motor 1 in real time.
Wind pressure sensor 32 includes upper cover, lower cover, upper cover and lower cover are fixing by snapping connection, on cover and be provided with positive pressure interface, under cover and be provided with negative port, upper cover and lower cover define atmospheric pressure cavity, are provided with the blast barrier film of flexibility in atmospheric pressure cavity, and atmospheric pressure cavity is divided into separate malleation chamber and negative pressure cavity by blast barrier film, this structure is easily installed, and dependable performance.
In this utility model, positive pressure interface or negative port are connected with blast Sampling Interface 31.As a example by negative port, after negative port is connected by pressure tube 33 with blast Sampling Interface 31, positive pressure interface will directly communicate with outside atmosphere, when blast Sampling Interface 31 produces negative pressure, flexible blast barrier film will move to negative pressure cavity, negative pressure cavity volume tails off, positive pressure cavity is long-pending becomes big, the magnet ring in wind pressure sensor 32 is made to progress in magnet ring containing cavity, because magnet ring progresses into thus changes the faradism sensibility reciprocal being arranged at the air-core inductance outside magnet ring containing cavity, real-time change situation by the available blast of the change of this faradism sensibility reciprocal.
When resistance of discharging fume in common flue increases, blast barrier film in wind pressure sensor 32 will extrude to negative pressure cavity, cause the change of faradism sensibility reciprocal in wind pressure sensor 32, the signal of telecommunication is transferred to controller 2 by holding wire by wind pressure sensor 32, controller 2 adjusts the rotating speed of motor 1 according to the program set, and improves the rotating speed of motor 1.Be conducive to quickly being drained by oil smoke, promote smoke discharging effect.
When resistance of discharging fume in common flue reduces, blast barrier film in wind pressure sensor 32 still extrudes to negative pressure cavity direction, amount of compression now diminishes, cause the change of faradism sensibility reciprocal in wind pressure sensor 32, the signal of telecommunication is transferred to controller 2 by holding wire by wind pressure sensor 32, controller 2 adjusts the rotating speed of motor 1 according to the program set, and reduces the rotating speed of motor 1.The most energy-conservation, and noise when can reduce work, improve the comfort level that cigarette machine uses.
In the present embodiment, controller 2 is stored in control program, when using direct current generator, the stepless time adjustment of direct current generator can be controlled to change discharge quantity of fan size.When using exchange cigarette machine, alternating current generator gear can be controlled thus change air force.
This utility model can adjust the rotating speed of motor, it is achieved wind, with pressing, improves smoke discharging effect, makes product more intelligent, to facilitate the use of consumer in real time effectively according to the change of blast in flue.
