Abstract
The utility model relates to a primary-secondary longitudinal air exhausting channel comprises an air channel outer shell 1, a division board 2 is arranged in the air channel outer shell 1, and the air channel is divided into a primary air channel 3 and a secondary air channel 4. The primary air channel 3 is bigger than the secondary air channel 4. The base of the secondary air channel 4 is sealed, and the top is connected with the primary air channel 3 through the air outlet opening 5 which is arranged on the division board 2. An air inlet opening 6 is arranged on the air channel outer shell 1, and the air inlet opening 6 is connected with the secondary air channel 4. A gap 7 is arranged on one concurrent face of the secondary air channel 4 and the air channel outer shell 1 at the position of the base of the air channel. When the air channel is arrangedtled, the division boards 2 of the upper section air channel and the down section air channel are treated by sealing construction through the gap 7. The gap 7 can be enveloped when the division boards 2 of the upper section air channel and the down section air channel are ensured to be sealed strictly.
Description
Technical field
The utility model relates to vertical exhast duct that a kind of dwelling house is vertically concentrated exhaust system.
Background technology
Now in the technology vertically exhast duct two kinds of monotrysian type and primary-secondary types are arranged.The monotrysian type exhast duct needs to install in addition flap valve, and flap valve is easily clung by greasy dirt, needs regularly to clean, and it is not too convenient to use; The inside of primary-secondary type exhast duct need be provided with demarcation strip, and the air channel is divided into sub-air channel and female air channel.A concentrated exhaust system needs the more piece air channel to connect to combine, and the demarcation strip of two internodes is up and down installed when connecting, and because of it is in the inside in air channel, staff can't put in and carry out thin portion and handle, and imprudently slightly poorly sealed situation will occur.In a single day and the poorly sealed incident generation that just is certain to occur the smoke blowing taint of odour occurs, and to keep in repair also very difficult.Therefore, there is certain defective in existing vertical exhast duct.
The utility model content
The purpose of this utility model provides a kind of easy for installation, is easy to the vertical exhast duct of primary-secondary type of tight seal.
The vertical exhast duct of primary-secondary type of the present utility model has place, air channel shell, be provided with demarcation strip in place, air channel shell, the air channel is divided into female air channel and sub-air channel, described female air channel is greater than sub-air channel, the bottom sealing in sub-air channel, the top is connected with female air channel by the air outlet that is arranged on the demarcation strip.Offer air intake on the shell of air channel, air intake is connected with sub-air channel.On the sub-air channel of air channel bottom position and one of them face that the air channel shell overlaps, offer a breach, when the air channel is installed, by described breach upper and lower two demarcation strips that save air channels are carried out seal construction and handle, the demarcation strips in two joint air channels tightly are honored as a queen and just can be sealed the mouth of filling a vacancy about confirming.
The utility model compared with prior art has following advantage: the sealing operability to the demarcation strip in two joint air channels up and down in installation process is extremely strong, as not carrying out seal operation first between advancing, also can find and reform in the inspection work after this.This phenomenon of just having avoided occurring the smoke blowing taint of odour when using in the future takes place.Therefore the utility model is a kind of vertical exhast duct that is easy to tight envelope.
Content of the present utility model further illustrates with the following Examples.

Fig. 1 is the vertical view of exhast duct among the embodiment;
Fig. 2 is the sectional view of the A-A direction of Fig. 1;
Fig. 3 is the right view of Fig. 1, wherein:
(1) air channel shell; (2) demarcation strip; (3) female air channel; (4) sub-air channel; (5) air outlet; (6) air intake; (7) breach;
Embodiment: have place, air channel shell 1 referring to the vertical exhast duct of a kind of primary-secondary type of Fig. 1-Fig. 3, in place, air channel shell 1, be provided with demarcation strip 2, the air channel is divided into female air channel 3 and sub-air channel 4, described female air channel 3 is greater than sub-air channel 4, the bottom sealing in sub-air channel 4, the top is connected with female air channel 3 by the air outlet 5 that is arranged on the demarcation strip 2.Offer air intake 6 on the air channel shell 1, air intake 6 is connected with sub-air channel 3.On the sub-air channel 3 of air channel bottom position and one of them face that air channel shell 1 overlaps, offer a breach 7, when the air channel is installed, carry out seal construction by 7 pairs upper and lower two demarcation strips 2 that save air channels of described breach and handle, the demarcation strips 2 in two joint air channels tightly are honored as a queen and just can be sealed the mouth 7 of filling a vacancy about confirming.
