Detailed description of the invention
The core of the present invention is in that to disclose a kind of smoke exhaust pipe assembly, increases a ring-type joint in the end of smoke exhaust pipe, it is possible to dock reliable installation with check-valves.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
The smoke exhaust pipe assembly that the embodiment of the present invention provides, its core improvement is in that, including smoke exhaust pipe, check-valves and ring-type joint；
Wherein, ring-type joint is used for being arranged between smoke exhaust pipe and check-valves, and check-valves has the first installation portion, and ring-type joint has the second installation portion for being detachably fixed connection with the first installation portion.
Can be seen that from above-mentioned technical scheme, the smoke exhaust pipe assembly that the embodiment of the present invention provides, a ring-type joint is increased in the end of smoke exhaust pipe, second installation portion of this ring-type joint can be detachably fixed with the first installation portion of check-valves and be connected, adopt compared with adhesive tape bonding with prior art, this programme make the installation of smoke exhaust pipe and keep in repair more convenient, reliable, do not come off.In the first embodiment, as Figure 1-Figure 4, the first installation portion is hasp 121, and multiple hasps 121 are uniformly distributed circumferentially on the end face of check-valves 12, and the tongue of hasp 121 points to the axis of check-valves 12, using the teaching of the invention it is possible to provide fastening restoring force radially inward；Second installation portion be along ring-type joint 13 extend radially outwardly formed boss 131；The inward flange of hasp 121 is to the distance of check-valves 12 axis, less than the outward flange of boss 131 to the distance of ring-type joint 13 axis；So, hasp 121 can be fastened on the end face of boss 131, it is achieved the reliable docking of smoke exhaust pipe 11 and ring-type joint 13.
In order to optimize above-mentioned technical scheme further, on the movable end face being connected to check-valves 12 of hasp 121, snapped together by 121 check-valves of mobilizable hasp 22 and ring-type joint 23.Concrete, can be that the root that hasp 121 is connected with check-valves 12 adopts elastomeric material, so, when boss 131 at ring-type joint 13 needs to load, first hasp 121 radially can be broken into two with one's hands, after boss 131 is axially fitted to position, under the effect of elastic restoring force, hasp 121 buckles radially inward on the end face of boss 131 so that installment work is more convenient and laborsaving.
As preferably, the quantity of hasp 121 is four, being spaced 90 ° and be distributed in check-valves 12 for the end face that same smoke exhaust pipe 11 connects, the spacing of ring-type joint 13 and check-valves 12 is more than the spacing of ring-type joint 13 with smoke exhaust pipe 11, and its structure is referred to shown in Fig. 3 and Fig. 4.Certainly, those skilled in the art can adjust the particular number of hasp 121 according to actual needs, does not repeat them here.
Or, in the second embodiment, check-valves 22 and ring-type joint 23 are respectively provided with rotation card, screw mutually installation by revolving card；As shown in Figure 5-Figure 8, the first installation portion is the first projection being arranged on the periphery wall of check-valves 22, and first is protruding along being perpendicular to the extension of check-valves 22 axially direction, i.e. the rotation of check-valves in Fig. 6 and Fig. 8 card 221；Second installation portion is the second projection being arranged on the internal perisporium of ring-type joint 23, and second is protruding along being perpendicular to the extension of ring-type joint 23 axially direction, i.e. the rotation of ring-type joint in Fig. 6 and Fig. 7 card 231；The outward flange of the first projection is to the distance of check-valves 22 axis, more than the inward flange of the second projection to the distance of ring-type joint 23 axis.
In the specific embodiment that this programme provides, the quantity of the first projection is multiple, is distributed in and is perpendicular in the same periphery that check-valves 22 is axial；The quantity of the second projection is multiple, is distributed in and is perpendicular in the same periphery that ring-type joint 231 is axial.It is understood that the spacing distance between adjacent two check-valves rotation card 221 should more than the length dimension of ring-type joint rotation card 231, to ensure the normal assembling of both, its structure is referred to shown in Fig. 7 and Fig. 8.
Or, in the third embodiment, check-valves 32 and ring-type joint 33 are respectively provided with screw thread, are screwed mutually installation by screw thread；As shown in Fig. 9-Figure 12, the first installation portion is the external screw thread 321 being arranged on the periphery wall of check-valves 32, and the second installation portion is be arranged on the internal perisporium of ring-type joint 33, for the female thread 331 coordinated with external screw thread 321.
In order to reach better seal effect, the smoke exhaust pipe assembly that the embodiment of the present invention provides, also include the gasket seal of annular, gasket seal is arranged in the cannelure of the end face of check-valves, for coordinating with the end face of ring-type joint.By adopting gasket seal to seal smoke exhaust pipe and non-return valve seat, it is ensured that oil smoke will not leak.Its structure can respectively refer to shown in Fig. 2, Fig. 6 and Figure 10 in three kinds of specific embodiments.
In the specific embodiment that this programme provides, the end of smoke exhaust pipe and the first end grafting of ring-type joint coordinate；Its structure is referred to described in Fig. 2 and Fig. 6, and the first end of ring-type joint has circular groove structure, coordinates for the end tube wall grafting with smoke exhaust pipe, and the gauge of the width dimensions of ring-type joint ring connected in star and smoke exhaust pipe end tube wall is interference fit；Second end of ring-type joint has the second installation portion.In order to not affect normal smoke evacuation, the sectional dimension of ring-type joint should not be reduced to the second end by its first end.
Present invention also offers a kind of range hood, including smoke exhaust pipe assembly, its core improvement is in that, smoke exhaust pipe assembly is above-mentioned smoke exhaust pipe assembly, it is possible to reach to solve the problem that the installation of general smoke exhaust pipe and check-valves bothers, easily comes off, easily leaks oil smoke.
In sum, the smoke exhaust pipe assembly that the embodiment of the present invention provides, adopting a kind of smoke exhaust pipe mounting structure reliably, increase a ring-type joint in the end of smoke exhaust pipe, this ring-type joint can utilize the arbitrary connected mode in button bit, rotation card, screw thread to install with check-valves；And between end face and the check-valves of this ring-type joint simultaneously, increase gasket seal, make oil smoke, waste oil to reveal.The embodiment of the present invention additionally provides a kind of range hood applying above-mentioned smoke exhaust pipe assembly, can make the installation of smoke exhaust pipe and check-valves and keep in repair more convenient, reliable, do not come off, stop the leakage of oil smoke, waste oil.
In this specification, each embodiment adopts the mode gone forward one by one to describe, and what each embodiment stressed is the difference with other embodiments, between each embodiment identical similar portion mutually referring to.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses the present invention.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
