Abstract
The utility model relates to an opening auxiliary mechanism of a smoke deflector of an extractor hood. The smoke deflector is rotatably arranged on an aslant-arranged extractor hood panel, and can be attracted by an electrified electromagnetic mechanism, and the smoke deflector is connected with a gas spring and can be opened under the action force of the gas spring. The opening auxiliary mechanism is characterized by comprising a power drive mechanism, a cam connected with the output shaft of the power drive mechanism, and a lever the first end of which supports and contacts with the cam, wherein the second end of the lever is connected with the gas spring. Compared with the prior art, the opening auxiliary mechanism has the advantages that through arranging the power drive mechanism connected with the gas spring, the cam and the lever, when the smoke deflector or electromagnetic mechanism is stuck by greasy dirt, the smoke deflector can not be opened by means of the dead weight after the electromagnetic mechanism is demagnetized, when the smoke deflector can not be opened, the opening auxiliary mechanism can provide an initial force when the smoke deflector is opened to ensure that the smoke deflector is separated from the electromagnetic mechanism, and the smoke deflector is normally opened.
Description
Technical field
The utility model relates to a kind of auxiliary body that opens of lampblack absorber smoke barrier.
Background technology
Existing lampblack absorber with the flip-shell smoke barrier, smoke barrier 1 ' rotates and is arranged on the kitchen ventilator panel 2 ' that is obliquely installed, electromagnetic mechanism 3 ' after smoke barrier 1 ' can be energized holds, and smoke barrier 1 ' is connected with air spring 4 ' and can under the active force of air spring, smoke barrier be opened.During the smoke barrier closed condition, air spring is in self-locking state, smoke barrier be there is no the effect of power, and smoke barrier holds the location by electromagnetic mechanism, shown in accompanying drawing 1.When electromagnetic mechanism outage demagnetization, just begun smoke barrier and opened by deadweight, open certain angle after the air spring release begin smoke barrier is exerted oneself, at last smoke barrier is opened.Shown in accompanying drawing 2.
Sucker or electromagnetic mechanism on smoke barrier are clung by greasy dirt, although after the electromagnetic mechanism demagnetization, smoke barrier also can't be opened by deadweight, at this moment air spring does not have starting force, can't normally smoke barrier be opened, and cause lampblack absorber normally not use.
The utility model content
Technical problem to be solved in the utility model is that a kind of auxiliary body that opens of lampblack absorber smoke barrier is provided for above-mentioned prior art, this mechanism can be to starting force of air spring when smoke barrier is opened, smoke barrier is separated with electromagnetic mechanism, guarantee that smoke barrier normally opens.
the utility model solves the problems of the technologies described above the technical scheme that adopts: this lampblack absorber smoke barrier open auxiliary body, described smoke barrier plate rotates and is arranged on the kitchen ventilator panel that is obliquely installed, electromagnetic mechanism after described smoke barrier can be energized holds, described smoke barrier is connected with air spring and can under the active force of air spring, smoke barrier be opened, it is characterized in that: the described auxiliary body that opens comprises a power-driven mechanism, the cam that is connected with described power-driven mechanism output shaft, the lever that first end and described cam offset and contact, the second end of described lever is connected with described air spring.
As improvement, described power-driven mechanism is fixed on a support, and this support is fixed on the kitchen ventilator panel inboard, and the fulcrum of described lever is fixed on described support.
Preferably, described power-driven mechanism is stepper motor.
Compared with prior art, the utility model has the advantage of: by power-driven mechanism, cam and the lever that is connected with air spring is set, when smoke barrier or electromagnetic mechanism are clung by greasy dirt, after the electromagnetic mechanism demagnetization, smoke barrier also can't be opened by deadweight, when causing smoke barrier to open, to a starting force, smoke barrier is separated with electromagnetic mechanism when the mechanism that the utility model provides can open to smoke barrier, guarantee that smoke barrier normally opens.

The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
the lampblack absorber smoke barrier that the utility model provides open auxiliary body, be applicable to the lampblack absorber with the flip-shell smoke barrier, the panel 1 of this lampblack absorber with the flip-shell smoke barrier is obliquely installed, and the upper end of smoke barrier 2 is rotatably connected on panel 1, the lower end of smoke barrier is provided with the sucker 4 that can be held by electromagnetic mechanism 3, the rotating mechanism 10 of smoke barrier 2 upper ends is connected with air spring 5 and can under the active force of air spring 5, smoke barrier 2 be opened, the auxiliary body that opens that the present embodiment provides comprises a stepper motor 6, the cam 7 that is connected with described stepper motor 6 output shafts, the lever 8 that first end and described cam 7 offset and contact, the second end of described lever 8 is connected with described air spring 5, stepper motor 6 is fixed on a support 9, and this support 9 is fixed on kitchen ventilator panel 1 inboard, and the fulcrum of described lever 8 is fixed on described support 9, and is shown in Figure 3.
When the contact surface of sucker 4 or electromagnetic mechanism 3 is covered by greasy dirt, after electromagnetic mechanism 3 demagnetizations, because sucker 4 is clung by greasy dirt, smoke barrier also can't be opened by deadweight, at this moment, rotating band moving cam 7 by stepper motor 6 rotates, cam 7 rotates and prizes lever 8, and is after cam forwards certain position to, shown in Figure 4, lever 7 reaches maximum position, at this moment, under the active force of lever 7, be equivalent to 5 one starting forces of air spring, sucker is separated with the electromagnetic mechanism contact-making surface, guarantee that smoke barrier normally opens.
Claims (3)
1. a lampblack absorber smoke barrier opens auxiliary body, described smoke barrier plate rotates and is arranged on the kitchen ventilator panel that is obliquely installed, electromagnetic mechanism after described smoke barrier can be energized holds, described smoke barrier is connected with air spring and can under the active force of air spring, smoke barrier be opened, it is characterized in that: the described auxiliary body that opens comprises a power-driven mechanism, the cam that is connected with described power-driven mechanism output shaft, the lever that first end and described cam offset and contact, the second end of described lever is connected with described air spring.
