[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figures 1 to 3 As shown, the utility model provides a range hood that is easy to disassemble and maintain, including a range hood 1;

[0023] A filter 2 is arranged at the input end of the range hood 1;

[0024] The top and bottom of the surface of the range hood 1 are fixedly connected with a connecting block 3, and the surface of the connecting block 3 is movably connected with a claw 4 through a pin shaft. The claw 4 extends from the side of the connecting block 3 to the side of the filter 2 and contacts with the surface of the filter 2. A rotating wheel 5 is provided on one side of the filter 2, and a screw rod 6 is fixedly connected to the right end of the rotating wheel 5. The end of the screw 6 away from the rotating wheel 5 penetrates the range hood 1 and extends to the outside of the range hood 1. An extrusion rod 7 is threadedly connected to the surface of the screw rod 6, and an extension plate 8 is fixedly connected to the inner side of the claw 4, and the outer end of the extrusion rod 7 contacts with the inner side of the extension plate 8.

[0025] refer to Figure 2 A guide rod 9 is fixedly connected to the surface of the range hood 1 , and the extrusion rod 7 is sleeved on the surface of the guide rod 9 and slidably connected to the guide rod 9 .

[0026] As a technical optimization solution of the present invention, by providing the guide rod 9, the extrusion rod 7 can be limited to prevent the extrusion rod 7 from tilting during the movement.

[0027] refer to Figure 2 A reinforcing rib 10 is fixedly connected to the outer side of the claw 4 , and one end of the reinforcing rib 10 away from the claw 4 is fixedly connected to the surface of the extension plate 8 .

[0028] As a technical optimization solution of the present invention, by providing reinforcing ribs 10 , the extension plate 8 can be supported, and the contact area between the extension plate 8 and the claw 4 can be increased.

[0029] refer to Figure 2 An opening 11 is provided on the surface of the extrusion rod 7 , and a sleeve 12 sleeved on the surface of the screw rod 6 is fixedly connected to the interior of the extrusion rod 7 , and the sleeve 12 is threadedly connected to the screw rod 6 .

[0030] As a technical optimization solution of the present invention, by providing the opening 11 and the sleeve 12, the overall strength of the extrusion rod 7 can be reduced while maintaining the thread engagement area.

[0031] refer to Figure 2 Both ends of the extrusion rod 7 are movably connected with rollers 13 through pins, and the outer surface of the roller 13 contacts the surface of the extension plate 8.

[0032] As a technical optimization solution of the present invention, by providing the roller 13, the extrusion rod 7 can be protected and the friction generated when the extrusion rod 7 and the extension plate 8 are in contact and friction can be reduced.

[0033] refer to Figure 2The surface of the range hood 1 is fixedly connected with an elastic plate 14 located inside the claw 4. The side of the elastic plate 14 away from the range hood 1 is in contact with the surface of the claw 4, and the elastic plate 14 is elastic.

[0034] As a technical optimization solution of the present invention, by providing a spring plate 14, the claw 4 can be supported so that the claw 4 has an elastic reset effect.

[0035] The working principle and use process of the utility model are as follows: when in use, the filter 2 can filter the range hood 1. When the range hood 1 needs to be maintained, the rotating wheel 5 is first rotated, and the rotating wheel 5 drives the screw 6 to rotate. The screw 6 uses the thread to push the extrusion rod 7 to move horizontally. When the extrusion rod 7 is out of contact with the extension plate 8, the extension plate 8 that has lost the extrusion drives the claw 4 to swing with the pin shaft as the axis. When the claw 4 is out of contact with the filter 2, the user can separate and disassemble the filter 2.

[0036] In summary: the range hood that is easy to disassemble and maintain can improve the existing connection method between the filter 2 and the range hood 1, replacing the operating steps of fixed installation through a large number of threaded components, making it easier for users to disassemble the filter 2 and improving the maintenance efficiency of the range hood 1.
