Description

Insect prevention counterseal exhaust outlet

Technical field

The utility model relates to a kind of exhaust outlets, more particularly to a kind of insect prevention counterseal exhaust outlet.

Background technique

In the prior art, oil smoke is directly discharged to outdoor by connecting tube by the range hood being arranged in household kitchen, It also will appear some problems simultaneously, A. is when blowing, rain or when outdoor has peculiar smell, outdoor has gas, rainwater or the wind of peculiar smell Sand can flow backward along connecting tube into range hood and interior, cause range hood water inlet impaired, and the decline of fume eliminating effect, interior is altered Enter peculiar smell, influences indoor environment；B. extraneous biology intrusion, as mosquitos and flies, cockroach, mouse enter range hood and room from connecting tube It is interior, come to the cleaning tape of indoor sanitation difficult.

The reverse irrigation that people blow in order to prevent, rain thus is provided with unidirectional slew page in connecting tube, existing to prevent to flow backward The generation of elephant, but unidirectional slew page needs certain wind-force and can just open unidirectional slew page in normal air draft, thus Need to increase the air draft power of range hood, increasing exhaust cost, after a period of time, unidirectional slew page can be by greasy dirt It pastes and cannot normally open, need that unidirectional slew page is cleared up and replaced, to seriously affect ventilation effect, and need Timed maintenance is wanted, inconvenience has been brought.

Utility model content

In view of this, the main purpose of the utility model is to provide a kind of insect prevention counterseal exhaust outlets, by this technology side Case, can not only guarantee the normal discharge of oil smoke, and can prevent the intrusion of mouse, cockroach and mosquitos and flies, while can also be to prevent Only since the discharge of greasy dirt causes the effect of air draft to decline.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of insect prevention counterseal exhaust outlet, It include terminal pad, the terminal pad is fixed on external wall corresponding to house exhaust outlet, further includes anti-foreign matter section and radix saposhnikoviae Section, the rear portion of the terminal pad, anti-foreign matter section and the windproof rounded tubulose of section, at the rear portion of terminal pad, the both ends of anti-foreign matter section It is respectively arranged with joint face with the front end of windproof section, is connected as one between two adjacent joint faces by glue seals, There are four groove, four outer ends of cross brace are installed on corresponding respectively for setting on the joint face of the anti-foreign matter section front end In groove, the anti-drilling net of spiral helicine foreign matter is provided on cross brace surface, the radix saposhnikoviae section is provided with air port, wind in middle part The support of bearing is respectively set in two sides among mouth top, and hinged shaft both ends are separately mounted in the bearing of the corresponding support of bearing, wind On plate is arranged before air port, hinged shaft is hinged with aerofoil upper end.

The inclined wind-guiding partition of forward downward is provided in the radix saposhnikoviae section, the wind-guiding septum plane and vertical direction Angle is 10 ° -20 °, and the air port is arranged on wind-guiding partition middle position.

Protection against rodents item is provided on before the terminal pad.

The adhesive tape of hollow softness is embedded on the inlet front end face or on corresponding aerofoil face.

Beneficial effect after by adopting the above technical scheme is: a kind of insect prevention counterseal exhaust outlet, by the technical program, not only It can guarantee the normal discharge of oil smoke, and the intrusion of mouse, cockroach and mosquitos and flies can be prevented, and in hinged shaft and aerofoil and hinged shaft Under the dual freedom degree of the support of bearing, prevent the discharge due to greasy dirt from the effect of air draft being caused to decline, by before air port to The setting and insertion adhesive tape of front lower place tilt angle, effectively raise aerofoil to the unidirectional blocking in air port, reduce simultaneously The wind speed demand of aerofoil is opened, the wind gathering effect that cooperation air port is arranged below increases outlet air flow velocity and pressure, improves air draft Effect.
