The first flap 211 and the third flap 213 are attached to both sides of the second flap 212, respectively. Therefore, the first folding edge 211, the third folding edge 213 and the second folding edge 212 do not need to be separated by adding other parts, and the strength is higher compared with the case that the first folding edge 211 and the third folding edge 213 are separated. The first and third folded

edges

211 and 213 serve to reinforce the strength between the back panel 2 and the smoke collecting cage. The second flange 212 is used to be attached to the case 3 to reinforce the strength of the back panel 2 after the smoke collecting hood is attached to the case 3. The second flange 212 of the smoke collecting hood back plate 2 is connected with the box body inclined plane 31 through the screw 4, so that the strength of the back plate 2 is enhanced.

Fig. 4 shows a front view of a range hood provided by the present invention. Fig. 5 shows a cross-sectional view along line a-a of fig. 4 in accordance with the present invention. Fig. 6 shows an enlarged view of portion B of fig. 5 provided by the present invention.

The range hood of the embodiment of the utility model comprises the smoke collecting hood and the box body 3. The case 3 is connected to the connecting portion 13 of the smoke collecting hood.

As shown in fig. 3 to 6, the smoke collecting hood is used to collect smoke. The box 3 is generally disposed in a cavity on the fume collecting hood to prevent the fumes from directly contacting it. The flue gas that collection petticoat pipe collected is transmitted to the pipeline through box 3.

In a preferred embodiment of the present invention, the case 3 includes a case slope 31, and the case slope 31 is coupled to the second flange 212.

As shown in fig. 3, 5 and 6, the second folded edge 212 is attached to and bonded to the case slope 31, so that the strength of the back panel 2 can be enhanced.

In a preferred embodiment of the utility model, screws 4 pass through the counter-sunk table 23 of the back plate 2 to fixedly attach the second flange 212 to the inclined surface 31 of the box.

As shown in fig. 3 and 5, the number of the screws 4 may be one or more, and preferably 4. The inclined plane 31 and the second folding edge 212 of the box body are provided with holes corresponding to the positions of the sinking platforms 23 so as to be convenient for connection.

The range hood of the utility model comprises a smoke collecting hood and a box body 3. A box body 3 is arranged in the cavity on the fume collecting hood. If the strength of the back plate 2 is insufficient, once vibration or drop occurs during transportation or carrying due to the weight of the case 3, severe plastic deformation occurs, thereby making it impossible to use. If a reinforcing member is additionally arranged, the cost is increased, the installation difficulty is increased, and the mass production is not facilitated. The application utilizes the upper folding edge 21 and the lower folding edge 22 to combine the backboard 2 and the smoke collecting hood main body 1 and the box body 3, thereby realizing that the strength of the backboard 2 is enhanced without increasing the characteristics of parts utilizing the self.
