After the second connection portion is clamped into the limiting space, the second clamping strip 304 can limit the second connection portion to ensure the stability between the noise reduction component 2 and the side wall 101.

[0084] Furthermore, the mounting portion is disposed close to the upper side of the side wall 101 , and the mounting portion may specifically be a mounting groove disposed on the inner wall surface of the side wall 101 .

[0085] The connecting member 5 can be a right angle bracket, including a first fixing portion 501 and a second fixing portion 502 arranged at an angle, the first fixing portion 501 and the second fixing portion 502 are both in the form of a sheet, the first fixing portion 501 is provided with a first connecting hole 5011, the number of the first connecting holes 5011 is the same as the number of the mounting slots and corresponds to each other, the second fixing portion 502 is provided with a second connecting hole 5021, preferably, the first fixing portion 501 and the second fixing portion 502 are arranged vertically. The first fixing portion 501 is fixedly connected to the inner wall surface of the side wall 101 by welding, and the first connecting hole 5011 is connected to the mounting slot, the inner wall of the mounting slot is provided with an internal thread, and a screw can be used to pass through the first connecting hole 5011 and be threadedly connected to the mounting slot, so that the connecting member 5 is fixed to the mainframe case 1 by welding, and the first fixing portion 501 is connected to the mounting slot by screws to play a reinforcing role, so as to effectively strengthen the connection strength between the connecting member 5 and the side wall 101 of the mainframe case 1.

[0086] Furthermore, a convex portion 201 is provided on a side surface of the noise reduction component 2 facing away from the side wall 101 near the upper side edge, so that the noise reduction component 2 is locally thickened to form the convex portion 201, and the convex portion 201 provides sufficient thickness for the third connecting portion 202 to be connected to the connecting component 5. The third connection part 202 is arranged on the protrusion 201, and the third connection part 202 is arranged on the upper side of the rectangular frame of the noise reduction component 2. The third connection part 202 has a groove structure, and the inner wall of the third connection part 202 is provided with an internal thread. When the second connection part is clamped in the limiting space, since the limiting space has an upward opening, the noise reduction component 2 can be pushed upward for a distance, so that the protrusion 201 is fitted with the second fixing part 502 of the connecting member 5, and the third connection part 202 can be connected with the second connecting hole 5021, that is, the fastener 503 can be used to fix the connecting member 5 and the noise reduction component 2, so that the noise reduction component 2 is fixed in the current position. At the same time, the second clamping strip 304 can still block the noise reduction component 2 to prevent the bottom edge of the noise reduction component 2 from escaping from the limiting space, and the bottom edge of the noise reduction component 2 and the limiting space can maintain a mutually clamped state.

[0087] To sum up, the range hood host provided in the embodiment of the present application is provided with an installation part, a first connecting part 3 and other structures in the host case 1, and cooperates with the connecting member 5 to complete the installation and fixation of the noise reduction component 2 inside the host case 1, effectively avoiding the exposure of the screw end caps that occur in the traditional connection method, thereby significantly improving the refinement of the appearance of the host, and effectively avoiding the risk of oil leakage along the screw hole at the connection between the noise reduction component 2 and the host case 1, which not only improves the aesthetics of the range hood using this range hood host, but also eliminates the need for special treatment of the leaked oil, thereby improving the user experience.
