Embodiment Construction

[0018] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] figure 1 It is a schematic diagram of the overall structure of the present invention, including an inner tuyere 2 , an inner casing 3 , an outer casing 5 , a filter layer 6 and an outer tuyere 7 . The inner tuyere 2 has a tuyere sleeve and a tuyere flange, preferably engineering plastics through injection molding, and its structure is preferably a known inner wall tuyere, including at least a disc tuyere, a louver tuyere and a rotating tuyere. The tuyere sleeve has a sealing ring on the outside, and is connected and fastened to the inner wall of the inner casing 3 through the sealing ring. The tuyere flange abuts against the inner wall surface 1 . The number of the sealing rings is not less than 2, preferably known rubber or silicone materials. In order to prevent the displacement of the sealing ring, the t...

Abstract

The invention relates to a wall air vent assembly mounted indoors, and belongs to the technical field of building ventilation and mechanical structures. The wall air vent assembly comprises an inner air vent (2), an inner sleeve (3), an outer sleeve (5), a filter layer (6) and an outer air vent (7), wherein the outer sleeve (5) has a sleeve elastic part (53), so that the outer sleeve (5) can contract, after contraction, the diameter of the outer sleeve (5) is not larger than the diameter of a wall hole, after stretching out of the wall hole, the outer sleeve (5) can recover, and the outer sleeve (5) and an outer wall surface (4) are bonded, sealed and fixed; the inner sleeve (3) and the outer sleeve (5) and the wall hole are bonded; the mounting is convenient, and the sealing is reliable; during mounting, diameters of the outer sleeve (5) and the inner sleeve (3) are not larger than the diameter of the wall hole, and the wall hole is not damaged; a soft string penetrates through the outer sleeve (5), and the outer sleeve (5) can be effectively prevented from falling outdoors; the inner sleeve (3) can be cut on the installation site to adapt to wall bodies with different thicknesses; and during maintenance and cleaning, the outer air vent (7), the filter layer (6) and the inner air vent (2) are assembled and disassembled through the inner sleeve (3) indoors, and assembly and disassembly are convenient and quick.

Description

1. Technical field [0001] The invention relates to a wall-through tuyere assembly, which belongs to the technical field of building ventilation and mechanical structure. 2. Background technology [0002] The through-wall air outlet is installed on the wall of the building for ventilation and is widely used in residences, broadcasting studios, hospitals, theaters, classrooms, concert halls, libraries, entertainment halls, lounges, offices, shops, hotels, restaurants and gymnasium etc. In the prior art, the installation of the through-wall tuyere should firstly drill a hole in the wall, and then install the tuyere on the outside of the outer wall to ensure that the tuyere is sealed with the wall to prevent rainwater from entering the wall. During the construction of the exterior walls of high-rise buildings, the risk is relatively large and there are potential safety hazards. [0003] There have been proposed wall-mounted air vents for indoor installation. The invention pat...
