Fig. 1 shows the front schematic view of one embodiment of smoke exhaust pipe comprising smoke pipe ontology 1 and with smoke exhaust pipe sheet
The reducer union 2 of 1 one end of body connection.
Fig. 2 shows the schematic diagram of assembly method between smoke evacuation tube body 1 and reducer union 2, discharge fume tube body 1 and variable diameter
One end that connector 2 docks has the first threaded portion 10, correspondingly, has in the butt end of reducer union 2 and smoke evacuation tube body 1
There is the second threaded portion 20, is configured as to dock between the first threaded portion 10 and the second threaded portion 20, it can be by as shown in Figure 2
Mode turn the first threaded portion 10 or the second threaded portion 20 so that mutually being revolved between the first threaded portion 10 and the second threaded portion 20
It closes, is only connected by being threadedly engaged between smoke pipe ontology 1 and reducer union 2.
Due in traditional smoke exhaust pipe, discharge fume between tube body 1 and reducer union 2 be by clip it is fixed after, winding aluminum again
Foil belt is reinforced and is sealed, attaching complex steps, and required accessory is also more.Pass through the first threaded portion 10 and the second spiral shell
Smoke pipe ontology 1 is connect by being threadedly engaged between line portion 20 with reducer union 2, is assembled and is sealed all to be connected through a screw thread and come in fact
It is existing, eliminate aforementioned additional accessory so that user can convenient and fast being made by manufacturers or users, the user experience is improved.
Although one embodiment of this smoke exhaust pipe is as described above, the still smoke exhaust pipe phase in the other embodiments of this smoke exhaust pipe
It may have more details in many aspects for above-described embodiment, and at least part of these details can have
The variation of multiplicity.At least part in this details and a little variations is illustrated with some embodiments below.
In an embodiment of smoke exhaust pipe, the diameter of the first threaded portion 10 is less than the diameter 20 of the second threaded portion,
To be that the first threaded portion 10 is screwed into the second threaded portion 20 when tube body 1 of discharging fume needs to be assembled with reducer union 2
Among assembled, be arranged so that flue when smoke evacuation will not be led in the first threaded portion 10 due to the second threaded portion 20
It is caused to be stopped by reducer union 2.To improve the efficiency of smoke evacuation.
In another embodiment of smoke exhaust pipe, the diameter of the first threaded portion 10 be may be set to be greater than the second threaded portion
Diameter 20, to be connect by the way that the second threaded portion 20 is screwed among the first threaded portion 10 tube body 1 that will discharge fume with variable diameter
First 2 are assembled together.
In one embodiment, the thread cross section of the first threaded portion 10 and the second threaded portion 20 is trapezoidal, so that interior
External screw thread is adjacent to the conical surface to be not easy to loosen, and opposite rectangular thread, and contact area is big between thread, so that the leakage paths of gas
Length is longer, to play better seal effect.
Continuing with referring to Fig. 1, in one embodiment, the circle number that the first threaded portion 10 screws in the second threaded portion 20 is 3
More than circle, it ensure that the bonding strength and leakproofness between smoke evacuation tube body 1 and reducer union 2.
Fig. 3 shows the front schematic view of 2 one embodiments of reducer union, and reducer union 2 has multiple diameters
Different diameter-varying rings 21 is connected by interconnecting piece 22 between two neighboring diameter-varying ring 21, and the diameter of interconnecting piece 22 is two neighboring
In the variation pattern for being gradually reduced or increasing between diameter-varying ring 21, so that the variation between multiple diameter-varying rings 21 is smooth transition
Inclined-plane.Compared to directly with the vertically disposed interconnecting piece 22 of diameter-varying ring 21, which can be played the flue gas of discharge in smoke evacuation
The effect of drainage, without stopping to flue gas, so that smoke evacuation is more smooth, the effect of smoke evacuation also can be more preferable.With this
Meanwhile in smoke evacuation, since interconnecting piece 22 is in the inclined-plane drained to flue gas, edge between reducer union 2 and smoke evacuation tube body 1
The radial direction of smoke evacuation tube body 1 not will receive too big power, dock place with smoke evacuation tube body 1 to reduce reducer union 2
Abrasion, extend the service life of smoke exhaust pipe.
Fig. 4 shows the front schematic view of smoke evacuation 1 one embodiments of tube body, and smoke evacuation tube body 1 can be such as Fig. 4 institute
A kind of screwed pipe shown, the first threaded portion 10 constitute the pipe shaft of smoke evacuation tube body 1, so that in assembly, reducer union 2 can be with
The both ends of smoke evacuation tube body 1 are assemblied in, so that assembly is more convenient, selectivity is also more.
Although the utility model is disclosed as above with preferred embodiment, its be not for limiting the utility model, it is any
Those skilled in the art without departing from the spirit and scope of the utility model, can make possible variation and modification.Cause
This, all contents without departing from technical solutions of the utility model, according to the technical essence of the utility model to above embodiments institute
Any modification, equivalent variations and the modification made, each fall within the protection scope that the utility model claims are defined.
