Abstract

The utility model provides a fume back preventing device which comprises a cylinder body and an air door. The utility model is characterized in that the air door is movably sheathed on a threaded rod of the air door; the threaded rod of the air door is penetrated and fixed on the cylinder body; the air door is connected with two steel ropes; the other end of each of the two steel ropes is connected with a switch knob. The special fume back preventing device is designed to be arranged at the outlet position of a cooking fume remover. In the air door, the air door can be controlled to be opened and closed by pulling the steel ropes though pressing the switch knob by human hands. Thus the closing is accurate to be in a right position without influence of accumulated cooking fumes. The sealing effect is good, and the phenomenon of cooking fume mutually inversion is avoided and prevented.

Description

Anti-down precipitators

It is the anti-down precipitators that is assemblied on the kitchen hood that the utility model relates to a kind of.

At present, all be one to the shared flue of attic in many residential buildings, and the service time of kitchen hood is concentrated relatively, thereby it is very general to go here and there the phenomenon of oil smoke mutually, has brought some worries to the resident.For fear of the generation of mutual string oil smoke phenomenon, existing kitchen hood is provided with the situation generation that two semicircle plastic sheets prevent down cigarette at the exhaust opening place, but effect is bad.Because after using a period of time, the accumulation of oil smoke and dust makes two plastic sheets be difficult to self-return, even can not return, the phenomenon of string oil smoke be still failed basic the solution, brings inconvenience to people's life.People are expecting that a kind of technical scheme of the anti-down precipitators that can address the aforementioned drawbacks produces as early as possible.

The utility model purpose provides a kind of anti-down precipitators, and it can realize preventing going here and there mutually the purpose of oil smoke.

In order to achieve the above object, the technical solution of the utility model is: it comprises cylindrical shell and air door, it is characterized in that: being sleeved on the air door screw rod of described air door activity, this air door screw rod runs through and is fixed on the cylindrical shell, air door connects two steel wire ropes, and the other end of two steel wire ropes is connected on the switching knob.

Described air door is by two air flaps up and down and the rubber seal in the middle of being installed in is constituted.

Outside two steel wire ropes, be with pipe.

The utility model compared with prior art has the following advantages and good effect: 1, the anti-down precipitators of design one special use, it is installed in the exit of kitchen hood, its air door is by the manual switching knob pulling of people steel wire rope control air door switch, thereby close accurately and put in place, be not subjected to the oil smoke effect of accumulation, good sealing effect, thus avoided preventing that oil smoke from going here and there the generation of phenomenon, for people's life has brought convenience.2, air door is formed by three layers, and middle sealing ring can form closely with the inwall of cylindrical shell and fit, and has improved sealing effectiveness equally.

Describe in detail below in conjunction with accompanying drawing of the present utility model.

Fig. 1 is that the utility model is installed in the front view on the smoke suction and exhausting fan;

Fig. 2 is one of half sectional view of being shown in an open position of the anti-down precipitators air door of the utility model;

Fig. 3 is two of the half sectional view that is shown in an open position of the anti-down precipitators air door of the utility model;

Fig. 4 is the anti-down precipitators air door of a utility model vertical view in the closed position;

Fig. 5 is the anti-down precipitators air door of a utility model half sectional view in the closed position.

1, cylindrical shell; 2, air door; 3, air door screw rod; 4,5, lock screw; 6,7, pipe; 8,9, steel wire rope; 10, switching knob; 11, screw binding; 12, kitchen hood; 13, anti-down precipitators.

Referring to Fig. 1～Fig. 4, go here and there the problem of oil smoke mutually in order to solve a shared flue, the utility model provides a kind of anti-down precipitators of special use.Its formation is: being sleeved on the air door screw rod 3 of air door 2 activities in cylindrical shell 1, this air door screw rod 3 are run through and are fixed on the cylindrical shell 1, and the other end that air door 2 connects two steel wire rope 8,9, two steel wire ropes 8,9 is connected on the switching knob 10.Air door 2 is by two air flaps up and down and the rubber seal in the middle of being installed in is constituted.Outside two steel wire ropes 8,9, be with pipe 6,7, so that steel wire rope is played a protective role.

Referring to Fig. 5, two steel wire ropes 8,9 can be installed in kitchen hood 12 and the cylindrical shell 1, the so not only attractive in appearance but also steel wire rope 8,9 of can not making dirty.

During use, anti-down precipitators 13 can be contained on the kitchen hood 12.When needs were opened kitchen hood 12, rotatable switching knob 10 forwarded the position that air door 2 is opened to, and at this moment, air door 2 is in plumbness, and oil smoke can drain into flue; When need were closed anti-down precipitators 13, rotatable switching knob 10 forwarded the position that air door 2 is closed to, and at this moment, air door 2 is in level, formed airtightly, thereby can prevent effectively that the oil smoke of other resident family from sealing in.Characteristics of the present utility model are that it is manually controlled air door 2 by the people and opens and close, thereby closes accurately and put in place, not the phenomenon that can occur being not closed completely.
