The motor is a hysteresis motor. The electric check valve used for the exhaust outlet of a range hood has the advantages of simple and reasonable structure, adopting the hysteresis motor for opening and adopting reset spring for closing, having enough torque to overcome the oil scale clinging resistance, realizing tight closing and complete opening, eliminating the defects of insufficient opening and untight closing of the check valve in the prior art.
Description
Technical field:
The utility model relates to a kind of motorized non-return valve, more specifically to a kind of range hood exhaust outlet motorized non-return valve.
Background technique:
In the prior art; the common flue air draft is adopted in the kitchen more in the semi-high-rise housing; the phenomenon that oil smoke pours in down a chimney and the smoke evacuation ability weakens can take place after using a period of time in range hood; what its reason was that existing range hood exhaust outlet safety check adopts is that wind-force when relying on operation blows flap open, during shutdown by the sagging gravity structure of closing of flap deadweight.The defective of this structure is: the range hood grease adhesion that in use flap and valve body are easily accumulated in the safety check; blast can't be blown out full-gear to flap during operation; the flap that tilts has blocked the valve inner subchannel; cause that the smoke evacuation ability weakens; conduct oneself with dignity and to close by flap during shutdown, produce oil smoke and pour in down a chimney.
The model utility content:
The purpose of this utility model be provide at the prior art deficiency a kind of simple in structure, open closed freely, the range hood exhaust outlet motorized non-return valve of good seal performance.
The purpose of this utility model is to realize by following measure: a kind of range hood exhaust outlet motorized non-return valve, it has valve body, is installed in the flap in the rotating shaft, and its special way is to also have: the power-transmitting unit of being made up of motor, driving component, Returnning spring; Described driving component is the single-revolution plate, and motor power is passed to aforementioned flap rotating shaft through finger plate, and described Returnning spring is installed between valve body and the finger plate, and described power-transmitting unit is installed in the valve body power box.
Described motor is a hysteresis motor.
The limit position of described finger plate slewing area is equipped with limiting stopper.
The flange that plays airtight effect with flap is arranged on the described valve body.
Described finger plate is installed in the overhanging end of aforementioned flap rotating shaft, and the finger plate rotating shaft links to each other with the flap rotating shaft is coaxial, on the hysteresis motor output shaft gear is installed, and described gear is meshed with finger plate outer edge fan tooth.
Described finger plate is installed between the overhanging end and hysteresis motor of aforementioned flap rotating shaft, the finger plate rotating shaft links to each other with the flap rotating shaft is coaxial, key connecting, flap rotating shaft core, finger plate rotating shaft core, hysteresis motor output shaft axis coinciding are adopted in hysteresis motor output shaft and finger plate rotating shaft.
Compared with prior art, the range hood exhaust outlet motorized non-return valve that the utility model proposes, simple and reasonable for structure, adopt hysteresis motor unlatching and Returnning spring to close, there are enough moments of torsion to overcome grease adhesion resistance, accomplish to close tightly, unlatching puts in place, has eliminated the shortcoming that existing safety check is opened deficiency, fitted badly.

Embodiment:
Below in conjunction with accompanying drawing embodiment is elaborated:
In Fig. 1, an embodiment of the present utility model shown in Figure 2, a kind of range hood exhaust outlet motorized non-return valve, it has: valve body 1, the power-transmitting unit, the limiting stopper 7 that are installed in flap 2 in the rotating shaft, are made up of motor 4, driving component 3, Returnning spring 6.Described motor can adopt common motor, also can adopt hysteresis motor, adopts hysteresis motor in this example.Hysteresis motor power is passed to aforementioned flap rotating shaft through finger plate, and the finger plate rotating shaft links to each other with the flap rotating shaft is coaxial, and gear 10 is installed on the hysteresis motor output shaft in this example, gear 10 and 9 engagements of finger plate outer rim tooth sector.Limit position in the finger plate slewing area is equipped with limiting stopper 7, the slewing area of restriction finger plate.The flange that plays airtight effect with flap is arranged on the valve body in addition, guarantee the sealing after valve cuts out.Resetting of flap relies on Returnning spring 6 to realize that described Returnning spring is installed between valve body and the finger plate, and Returnning spring 6 spurs finger plates and drives the flap backward rotation during hysteresis motor dead electricity, and the flange 11 on flap and valve body is airtight.Described power-transmitting unit is installed in the valve body power box.When hysteresis motor was subjected to electricity, hysteresis motor output shaft 10 drove finger plate tooth sector 9 and rotates, gives flap, opens check valve with transmission of power again.
The advantage of hysteresis motor is when running into limiting stopper in the running and stop, its rotor continues rotation and the output shaft corner remains unchanged, and can not damage motor.The limit position of described finger plate slewing area is equipped with limiting stopper 7, and limited of finger plate stops when flap forwards maximum position to, and the hysteresis motor rotor continues rotation, but its output shaft corner remains unchanged with the rotation of restriction finger plate, flap.
Fig. 3, Fig. 4 have provided the mounting type of the two rotatingshafts of a kind of bivalve, between the two rotatingshafts of bivalve a pair of phase gear 12,13 is arranged, the finger plate rotating shaft is fixedlyed connected with the flap rotating shaft of one of them, gear 10 is installed, gear 10 and 9 engagements of finger plate outer rim tooth sector on the hysteresis motor output shaft.When hysteresis motor was subjected to electricity, hysteresis motor output shaft gear 10 drove finger plate tooth sector 9 and rotates, gives gear 12,13 with transmission of power again, drove the two rotatingshafts of bivalve and rotated opens check valve.When closing, rely on Returnning spring to close flap.
Fig. 5, Fig. 6 have provided the mounting type of another kind of single-lobe list rotatingshaft, the finger plate rotating shaft links to each other with the flap rotating shaft is coaxial in this example, the hysteresis motor output shaft adopts key to be connected 14 with the finger plate rotating shaft, flap rotating shaft core, finger plate rotating shaft core, hysteresis motor output shaft axis coinciding, this mounting type compact structure, institute takes up space few.When hysteresis motor was subjected to electricity, hysteresis motor directly drove finger plate, flap rotates, opens check valve.When closing, rely on Returnning spring to close flap.
The foregoing description does not constitute restriction of the present utility model, adopts the technological scheme that form obtained that is equal to replacement or equivalent transformation in every case, all drops within the protection domain of the present utility model.
