Description

Technical Field

[0001] The utility model relates to the technical field of exhaust hoods, in particular to a high-strength exhaust hood. Background Art

[0002] Patent document CN220624139U discloses a windproof exhaust hood used for building exhaust outlets (including glass holes). An exhaust outlet 7 is provided on the valve seat 8, a valve hinge 5 is provided above the exhaust outlet 7, a valve 3 protrudes outward, and a vertical, sheet-like vortex sheet 2 is provided below the top of the valve 3 and connected to the valve 3 as a whole. Since the vortex sheet 2 is perpendicular to the valve 3, the vortex sheet 2 is not subject to any resistance from the front when the valve 3 is opened, and acts as a windproof wall on the side to form a vortex that exerts pressure on the valve 3, so that the wind from the side not only cannot reduce the pressure of the valve 3 with an arc, but also generates pressure to close the valve 3. This simple-structured all-stainless steel windproof exhaust hood can not only ensure opening and closing in any natural environment, but also has a durable service life. A base 19 is provided at the back to make fixation more convenient.

[0003] However, most of the existing exhaust hoods adopt a prismatic appearance, which makes the exhaust hoods have low bending resistance, and the edges and corners are easy to scratch the staff, and the existing exhaust hoods have low positioning accuracy. Therefore, it is necessary to improve such a structure to overcome the above defects. Utility Model Content

[0030] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiment of the utility model provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiment of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0031] like Figure 1-4 As shown, a high-strength exhaust hood proposed by the utility model includes a supporting assembly component, an axial positioning component, a circumferential positioning component, a main body reinforcement component and a recessed connection component. An assembly space is arranged inside the supporting assembly component. The axial positioning component is formed in the supporting assembly component, and the axial positioning component is used to axially position the assembly component. The circumferential positioning component is formed in the circumferential positioning component, and the circumferential positioning component is used to circumferentially position the assembly component. The main body reinforcement component is formed in the supporting assembly component, and the supporting assembly component is structurally reinforced by the main body reinforcement component. The recessed connection component is formed in the supporting assembly component, and a space for gas flow is arranged in the recessed connection component.
