Description
Technical field
The utility model belongs to air draft pipe fitting, and specifically a kind of have the non-return air door of the automatic electric falling ice function, is particularly useful on the smoke duct of lampblack absorber.
Background technology
Existing lampblack absorber, is connected on chimney by airduct, uses the greasy dirt of middle accumulation and moisture can freeze because temperature is lower, causes air door flabellum to be difficult to open, can not discharge fume.
Utility model content
The technical assignment of the technical problems to be solved in the utility model and proposition overcomes greasy dirt that existing dead wind door in use accumulates and moisture can freeze because temperature is lower, cause air door flabellum to be difficult to the defect of opening, provide a kind of and there is the non-return air door of the automatic electric falling ice function.
For achieving the above object, of the present utility model have the non-return air door of the automatic electric falling ice function, comprise the air door passage with mount pad, it is characterized in that: in described air door passage, be connected with by radial axle the flabellum rotated around described axle, described air door passage peripheral hardware has the motor for rotating with described flabellum and the wiring board for electric machine rotation described in instruction, the rotating shaft of described motor is provided with signal trigger element, signal generating element is equipped with mutually with described signal trigger element, described motor with described flabellum turn to described air door passage is opened time described in signal trigger element trigger described in signal generating element generation signal instruction described in motor stop, described flabellum is provided with electrical heating wire.
As optimization technique means: described signal trigger element is magnet, described signal generating element is Hall element.
As optimization technique means: the outer wall of described air door passage is fixed with case, described motor, signal trigger element, signal generating element are positioned at described case.Described wiring board is positioned at described case.
As optimization technique means: described flabellum is provided with temp probe.
The beneficial effects of the utility model are: realize motor by the position relationship of signal trigger element and signal generating element and to move to command motor when being opened by air door passage with fan blade rotating and stop, by be provided with on flabellum electrical heating wire make because of greasy dirt and moisture freeze cause motor run occur stall phenomenon time, electrical heating wire heats, make to be attached on air door freeze oil, ice cube melts, until motor can run well; Further, electrical heating wire dry combustion method is avoided to damage air door and cause the accident by temp probe.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described further.
As shown in Figure 1, of the present utility model have the non-return air door of the automatic electric falling ice function, comprise the air door passage 2 with mount pad 1, during concrete enforcement, mount pad and air door passage can be structure as a whole, also can be Split type structure, be connected with by radial axle 3 flabellum 4 swayed in air door passage 2, air door passage 2 peripheral hardware has the motor 5 for rotating with flabellum and the wiring board 6 for instruction electric machine rotation, the rotating shaft of motor 5 (comprises rotating shaft itself and is attached to the subsidiary structure in rotating shaft, namely diagram is in rotating shaft, establish pivoted housing 7 as the component part of rotating shaft) be provided with signal trigger element 8, signal generating element 9 is equipped mutually with signal trigger element 8, motor 5 with flabellum 4 turn to air door passage 2 is opened time signal trigger element 8 triggering signal generating device 9 there is signal instruction motor 5 and stop, flabellum 4 is provided with electrical heating wire 10.
Concrete, signal trigger element 8 is magnet, and signal generating element 9 is Hall element.As the technological means of equivalent replacement, also can replace with photoelectric tube.The outer wall of air door passage 2 is fixed with case 11, motor 5, signal trigger element 8, signal generating element 9 are positioned at case.Wiring board 6 is positioned at case 11.Flabellum 4 is provided with temp probe 12.
The utility model can work in the following manner:
When wiring board 6 receives the signal of cigarette machine startup, by signal transmission to motor 5, rotate to open air door passage 2(air door passage by motor with flabellum 4 and be in the normally off shown in Fig. 3);
When flabellum 4 is from the normally off half-twist shown in Fig. 3 to position shown in Fig. 2, the magnet on machine shaft forwards to just to the position of Hall element, and Hall element senses changes of magnetic field, and motor automatic stop is operated, and completes air door passage and opens;
When motor run there is stall phenomenon time, heating can be started by the condition heater strip 10 of setting, make to cause stall freeze oil, ice cube (being usually attached in air door passage) melts, until motor starts to run well, heater strip stops heating;
When temp probe 12 senses that temperature reaches design temperature (as 75 °), automatically can stop the work of heater strip, be in dry-fire condition to prevent heater strip.
