Description
Technical field
The utility model is related to kitchen smoke-discharging equipment, and in particular to a kind of exhaust smoke check valve, including body, sealing valve plate and
Panel turnover mechanism.
Background technology
At present, mist extractor check-valves forms by mounting interface, housing and loaded on the panel turnover mechanism in housing.When air-flow promotes
When turnover panel opens gas channel, air-flow enters flue through housing, when air-flow stops, in the presence of gravity or recoil of spring power
Turnover panel is fallen after rise, and back draught passage is separated, and the peculiar smell of back draught cannot enter what is communicated with turnover panel opposite side through housing
Room, this is that the basic of exhaust smoke check valve uses function.
To block the flowing of back draught, the key technology of the structure is after ensureing that turnover panel falls after rise, between turnover panel and housing
Effectively sealing.What the requirement of the sealing should be strict.
In actual use, due in kitchen fume oil content it is denseer, and panel turnover mechanism uses simple mechanical rotating shaft more
Hinge, usually make shaft hinge Fa Sheng Nian Even, cause turnover panel open after can not fall after rise, or even can not open phenomenon when have hair
It is raw, cause oil smoke to pour in down a chimney, taint of odour, have impact on the indoor environment in kitchen.
Utility model content
In view of the shortcomings of the prior art, the technical problem that the utility model solves is how to ensure turnover panel in exhaust smoke check valve
Normally it is turned on and off, prevents oil smoke from pouring in down a chimney, taint of odour, while efficiently exclude oil smoke.
In order to solve the above technical problems, technical scheme provided by the utility model is a kind of exhaust smoke check valve, including body,
Sealing valve plate and panel turnover mechanism, sealing valve plate are controlled by the panel turnover mechanism installed in internal body and are turned on and off.
The panel turnover mechanism is arranged in control box, is mainly made up of motor, little gear and sector gear, the little gear
Ratcheting rotation is carried out on the motor shaft and with the sector gear, the sealing valve is inserted at the sector gear center
Disk rotating shaft and fixation, realized with the rotation of sector gear and sealing valve plate rotation is turned on and off controlling.
The internal body is straight cylinder structure, can farthest reduce suction and discharge oil smoke air drag, reach
Efficient smoke discharging effect.
Further, travel switch is each provided with left and right sides of the sector gear fan handle, when sector gear rotates,
When its fan handle encounters travel switch, motor stalls, being turned on and off for the sealing valve plate is completed.
As further improvement of the utility model, the intelligent inductor socket to connect with civil power, smoke exhaust ventilator are had additional
Attaching plug is inserted on the intelligent inductor socket, when smoke exhaust ventilator works, automatically turns on Smoke prevention check-valves；Work as smoke pumping
It is automatic to close Smoke prevention check-valves when machine is stopped；Realize smoke exhaust ventilator and exhaust smoke check valve synchronous working control.
In the case of power failure or panel turnover mechanism failure, to keep being turned on and off for sealing valve plate, set on the outside of body
There is emergency button, emergency button rotating shaft is connected with diaphragm seal, and manually controllable sealing valve plate is turned on and off.
Using the technical solution of the utility model, it can be ensured that sealing valve plate is normally turned on and off in exhaust smoke check valve,
Prevent oil smoke from pouring in down a chimney, taint of odour, while smoke exhaust ventilator suction and outlet are big, exhaust air rate is big, can efficiently exclude oil smoke, and in fact
Existing smoke exhaust ventilator and exhaust smoke check valve synchronous working control.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is little gear, sector gear and travel switch structure schematic diagram in the utility model.
Embodiment
Embodiment of the present utility model is further described below in conjunction with the accompanying drawings, but is not to of the present utility model
Limit.
Figures 1 and 2 show that the utility model and its internal structure signal, a kind of exhaust smoke check valve, including it is body 1, close
Valve block 2 and panel turnover mechanism are sealed, sealing valve plate 2 is arranged on to be controlled by the panel turnover mechanism inside body 1 and is turned on and off.
The panel turnover mechanism is arranged in control box 3, is mainly made up of motor 4, little gear 5 and sector gear 6, described small
Gear 5 is arranged on the axle of motor 4 and carries out ratcheting rotation with the sector gear 6, and institute is inserted at the center of sector gear 6
The rotary shaft of sealing valve plate 2 and fixation are stated, is realized with the rotation of sector gear 6 and the rotation of sealing valve plate 2 is turned on and off controlling.
The inside of body 1 is straight cylinder structure, can farthest reduce suction and discharge oil smoke air drag, reach
Efficient smoke discharging effect.
Further, travel switch 7 is each provided with left and right sides of the fan handle of sector gear 6, when sector gear 6 rotates
When, when its fan handle encounters travel switch, motor 4 stops operating, and completes being turned on and off for the sealing valve plate 2.
As further improvement of the utility model, the intelligent inductor socket to connect with civil power, smoke exhaust ventilator are had additional
Attaching plug is inserted on the intelligent inductor socket, when smoke exhaust ventilator works, automatically turns on Smoke prevention check-valves；Work as smoke pumping
It is automatic to close Smoke prevention check-valves when machine is stopped；Realize smoke exhaust ventilator and exhaust smoke check valve synchronous working control.
In the case of power failure or panel turnover mechanism failure, to keep being turned on and off for sealing valve plate 2, set in the outside of body 1
Emergency button 8 is equipped with, the rotating shaft of emergency button 8 is connected with diaphragm seal, and manually controllable sealing valve plate 2 is turned on and off.
Using the technical solution of the utility model, it can be ensured that sealing valve plate is normally turned on and off in exhaust smoke check valve,
Prevent oil smoke from pouring in down a chimney, taint of odour, while smoke exhaust ventilator suction and outlet are big, exhaust air rate is big, can efficiently exclude oil smoke, and in fact
Existing smoke exhaust ventilator and exhaust smoke check valve synchronous working control.
Embodiment of the present utility model is described in detail above in association with accompanying drawing, but the utility model is not limited to
Described embodiment.To those skilled in the art, the situation of principle and spirit of the present utility model is not being departed from
Under, various change, modification, replacement and modification are carried out to these embodiments and still fallen within the scope of protection of the utility model.
