Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-5, the present invention provides a technical solution:
the utility model provides a stabilize orifice plate device of air current, includes backing plate 1, and through-hole 2 has been seted up to the centre of backing plate 1, and the sound transmission groove 3 has evenly been seted up all around to through-hole 2, and the sound ring 4 has been inhaled in the inside of backing plate 1 is inlayed and is installed, and the collection hole 5 has been seted up to one side of backing plate 1, and mounting groove 6 has been seted up to one end one side of backing plate 1, and the inside slip joint of mounting groove 6.
In this embodiment, the through holes 2 are funnel-shaped, so as to change the flowing direction of the air flow and prevent the abrasion and leakage of the pipe wall of the air pipe 15.
In this embodiment, one end of the sound transmission groove 3 is communicated with the through hole 2, and the other end of the sound transmission groove 3 is attached to the inner side of the sound absorption ring 4, so that wind sound inside the through hole 2 can be effectively absorbed and isolated, and noise pollution can be prevented.
In this embodiment, one end of the collecting hole 5 is communicated with one side of the through hole 2, and the other end of the collecting hole 5 is bound with a sealed collecting bag 8 for collecting and managing dust and debris.
In this embodiment, the sliding groove 9 has been seted up to one side of backing plate 1, and the inside slip joint of sliding groove 9 has dead lever 10, and fixed mounting has spring 11 between dead lever 10 and the sliding groove 9, can be quick fix the position of filter screen 7.
In this embodiment, one end of the filter screen 7 is fixedly provided with a positioning hole 12, and the positioning hole 12 is slidably clamped with one end of the fixing rod 10, so that the filter screen 7 can be rapidly detached and installed.
