Abstract
The utility model relates to the technical field of smoke exhaust ventilators, in particular to a check valve with a smoke exhaust pipe. The check valve comprises a valve body and the smoke exhaust pipe connected to the valve body; an annular bulge loop is arranged at one end of the smoke exhaust pipe, a lantern ring is nested on the annular bulge loop, a groove and a decorative block are arranged on the lantern ring, a convex part is arranged in the position relative to the valve body and is inserted in the groove, and the decorative block is buckled on the valve body. The utility model has the benefits that firstly, the convex part on the valve body and the groove on the lantern ring are connected, thereby facilitating the connection of the smoke exhaust pipe to the valve body and the assembly and disassembly; secondly, an air vent is communicated with a gas vent, so that the problem that since vacuum is formed in the smoke exhaust pipe, the loose leaf in the check valve is difficult to open is prevented; thirdly, a convex element of the lantern ring is used for fixing the smoke exhaust pipe, so as to prevent the smoke exhaust pipe from getting loose; and fourthly, the oil fume flows to the smoke exhaust ventilator from an air flue through the air vent, and the connectivity and sealing performances between the valve body and the smoke exhaust pipe are better.
Description
Technical field
The utility model relates to the smoke exhaust ventilator technical field, specifically is a kind of check-valves with smoke exhaust pipe.
Background technology
In the prior art, the smoke pipe of cigarette machine is normally tied up to glue with several screw lock or with adhesive tape and is decided together, causes defectives such as there being the installation or removal inconvenience.For overcoming these defectives, the smoke exhaust pipe of cigarette machine and the syndeton of check-valves are improved.
The utility model content
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, and makes the smoke exhaust pipe installation or removal more easily with the check-valves of smoke exhaust pipe effectively and provide a kind of.
The utility model is realized with the following methods: comprise valve body, and be connected with smoke exhaust pipe on the valve body, one end of its described smoke exhaust pipe is provided with the ring-type bulge loop, be with the collar on the ring-type bulge loop, cover is equipped with groove and ornamental blocks, valve body is provided with protuberance relatively, and protuberance inserts in the groove, and ornamental blocks is buckled on the valve body.
Described collar inwall is provided with male member, and male member is close on the smoke exhaust pipe outside.
The side of described protuberance also is provided with madial wall, and madial wall and protuberance constitute an air flue, also establishes blow vent on the madial wall.
Described valve body is provided with a protruding curved surface protuberance, and madial wall and protuberance are arranged at the top of curved surface protuberance respectively.
On the described collar ventilating opening is set, blow vent set on ventilating opening and the madial wall communicates.
The inside ornamental blocks of projection on the described collar, an end of ornamental blocks extends the lower end of protuberance.
Described cover ring outer surface is provided with ribs.
Be provided with a horizontal stripe in the described curved surface protuberance, an arc groove is arranged on the horizontal stripe, the horizontal stripe both sides are provided with positioning socket.
The beneficial effects of the utility model are: 1, the protuberance on the valve body is connected with groove on the collar, help the comb cigarette and be connected in valve body, and installation and removal 2, ventilating opening communicate with blow vent, prevent to form in the smoke exhaust pipe vacuum, cause that loose-leaf in the check-valves is difficult to open 3, the male member of the collar is used for fixing smoke exhaust pipe, prevent to get loose; 4, ventilation password oil smoke flows back to from air flue in the smoke pumping, makes between valve body and the smoke exhaust pipe being connected better tightness.
