Description
Technical field
The utility model relates to arrive the smoke evacuation technology more particularly to a kind of connection structure of smoke pipe in kitchen.
Background technique
The connection type of existing range hood smoke exhaust pipe and common air flue check valve is all using adhesive tape winding or screw
Fixed mode, reliability is very poor with leakproofness, especially when smoke machine smoke evacuation pipe diameter is straight greater than common air flue check valve interface
The case where will appear big mouthpiece cover small nozzle when diameter, handles bad interface and is easy to unclamp explosion, in use meeting at this
The serious problems such as appearance is leaked out, oil leak even smoke pipe loosens.
Utility model content
In view of this, the utility model proposes a kind of connection structure of smoke pipe, to solve the company of smoke pipe in the prior art
The technical problem of reliability existing for binding structure and leakproofness difference.
A kind of connection structure of smoke pipe, including smoke pipe and check-valves, the smoke pipe include smoke end, and the check-valves includes
Bending tubes end further includes casing, and the smoke end of the smoke pipe is connected with the bending tubes end of the check-valves by described sleeve pipe, described
It can be shunk after casing is heated.In the technical scheme, the smoke pipe and check-valves are by casing connection, in order to improve smoke pipe
With the connection reliability and leakproofness of check-valves, the casing in the technical program can be shunk after heated, the set after contraction
Pipe can tightly entangle the smoke end of the smoke pipe and the bending tubes end of the check-valves, make the connection between smoke pipe and check-valves can
It leans on, is not susceptible to leakage cigarette.Further, described sleeve pipe is heat-shrinkable T bush, and heat-shrinkable T bush is made using the material of elasticity, as PE,
PVC, PET, ABS, EVA, Teflon, rubber etc..
Further, further include clamp device, the clamp device by described sleeve pipe be fastened on the check-valves into cigarette
On end.In practice, the bending tubes end of the check-valves is often smooth pipeline, and casing is socketed in smooth pipeline in order to prevent
Occurs the possibility for loosening or sliding after upper, the technical program is provided with clamp device, and the clamp device is tight by described sleeve pipe
Gu on the bending tubes end of the check-valves, so that casing is tightly attached under the effect of external force on the bending tubes end of the check-valves.It is excellent
The clamp device of choosing is hose clamp, naturally it is also possible to be the components that other are able to achieve the function, such as strap, adhesive tape, iron wire.
Further, in the outer surface depressions portion of the smoke pipe or/and extension.In the technical program recessed portion or/and
The effect of extension be after casing temperature distortion, can with the smoke pipe be socketed it is stronger and have better sealing
Can, in practice, the recessed portion or extension are generally ripple or gauffer, in other words the smoke pipe be usually bellows or
Person's aluminum foil pipe.
Further, the smoke end of the smoke pipe is variable diameter design.The technical program (is usually existed for smoke pipe diameter) it is greater than check-valves bending tubes end diameterWhen and design.When smoke pipe diameter is close to check-valves into cigarette
Hold diameterVariable-diameter structure is arranged in smoke pipe in Shi Wuxu.Variable diameter design is in order to which smoke pipe and check-valves preferably connect
The case where connecing, being not in the small nozzle of big mouthpiece cover described in background technique.Variable diameter is set by the smoke end of the smoke pipe
On the one hand design can increase the manufacture difficulty and cost of smoke pipe, on the other hand straight due to that can not predict smoke pipe before smoke pipe is installed
The relationship of diameter and check-valves bending tubes end diameter, can not the accurate mating suitable smoke pipe of diameter, for this purpose, the utility model also provides one
Kind alternative solution, i.e. increase reducer union, the reducer union are connected to the smoke end of the smoke pipe, and described sleeve pipe is socketed in institute
On the bending tubes end for stating reducer union and the check-valves.Likewise, in order to improve casing and reducer union socket reliability and
Leakproofness is equipped with recessed portion or/and extension in the reducer union.Recessed portion herein can be groove structure, stretch out
Portion can be muscle structure.
Further, recessed portion or/and extension are equipped in described sleeve pipe.This is also for raising smoke pipe and check-valves
Connection reliability and leakproofness, after described sleeve pipe is heated, what described sleeve pipe can be even closer is adjacent in smoke pipe and non-return
On valve, and then reach good connection effect.
Compared with prior art, the utility model is include at least the following beneficial effects:
1, the utility model improves connection reliability and leakproofness between smoke pipe and check-valves.
2, the utility model solves the matching connectivity problem between the smoke pipe of different-diameter and check-valves.
3, the utility model improves casing and smoke pipe, check-valves by setting recessed portion or/and extension
Between bonding strength.
