In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art can realize the application of other processes and / or the use of other materials.

[0050] The present application will be described below in conjunction with the drawings and with reference to specific embodiments:

[0051] Reference is made to Figures 1-5 The embodiments of the present application disclose an extractor hood, which comprises a smoke collecting device 100, a smoke extracting device 200 and a control box assembly 300.

[0052] The smoke collecting device 100 in the embodiments of the present application is provided with a flow guide plate 110, the smoke extracting device 200 comprises a casing 210 connected with the smoke collecting device 100, and the control box assembly 300 comprises a cover 310, a protective cover 320 connected with the cover 310 to enclose a containing space, and an electrical control 330 arranged in the containing space, wherein the protective cover 320 comprises a flow guide surface 321 located above the flow guide plate 110 and at the lower end of the casing 210, so as to guide the liquid in the casing 210 to flow from the flow guide surface 321 to the flow guide plate 110.

[0053] Specifically, in conjunction with Figure 1Since the control box assembly 300 comprises the cover 310, the protective cover 320 connected with the cover 310 to enclose a containing space, and the electric control 330 arranged in the containing space, the gas and liquid are prevented from entering the containing space through the enclosed containing space to protect the electric control 330 in the containing space from being eroded and damaged.

[0054] Since the smoke collecting device 100 is provided with the flow guide plate 110, the smoke extractor 200 comprises the cabinet 210 connected with the smoke collecting device 100, the control box assembly 300 is arranged in the smoke collecting device 100, and the protective cover 320 comprises the flow guide surface 321 located at the lower end of the cabinet 210 of the smoke extractor 200 and above the flow guide plate 110, so that the liquid flowing down from the inner surface of the cabinet 210 of the smoke extractor 200 is guided to the flow guide plate 110 of the smoke collecting device 100 through the flow guide surface 321, and then the liquid is guided to the oil cup of the smoke extractor through the flow guide plate 110, so that the liquid on the inner wall of the smoke extractor is guided without flowing into the control box, thereby avoiding the damage of the electric control 330 caused by the gas and liquid entering the control box.

[0055] Further, in combination with Figure 1 The flow guide surface 321 is a bent surface, of course, the flow guide surface 321 can also be an inclined surface, a curved surface, etc., as long as the liquid in the cabinet 210 can be guided to the flow guide plate 110, and the embodiments of the present application do not limit this. In the present embodiment, in order to reasonably utilize the space in the smoke extractor and avoid interference or disturbance between the flow guide surface 321 and other parts, the flow guide surface 321 is arranged as a bent surface, which can reduce the interference with or affect the arrangement of the flow guide plate 110 in the smoke extractor compared with an inclined surface.

[0056] Further, in combination with Figure 2 The flow guide surface 321 comprises the first flow guide sub-surface 322 and the second flow guide sub-surface 323 arranged in sequence from top to bottom and connected with the first flow guide sub-surface 322, the first flow guide sub-surface 322 is inclined from the lower end of the cabinet 210 to the flow guide plate 110, and the second flow guide sub-surface 323 is reversely inclined from the lower end of the first flow guide sub-surface 322 to the first flow guide sub-surface 322, so as to guide the liquid droplets 400 in the cabinet 210 to flow to the flow guide plate 110 in sequence through the first flow guide sub-surface 322 and the second flow guide sub-surface 323.

[0057] As a specific embodiment of the bent surface structure of the flow guide surface 321, the first flow guide sub-surface 322 in the embodiments of the present application is inclined from the lower end of the cabinet 210 to the flow guide plate 110, and this arrangement is to ensure that the control box has sufficient containing space to install the electric control 330. If the arrangement is reversely inclined to the flow guide plate 110, the volume of the containing space will be greatly reduced.

[0058] The second flow guide surface 323 in the embodiment of the present application is considered in view of the structural features of the flow guide plate 110 below, the flow guide plate 110 is provided with the smoke inlet 120, when the range hood works, the oil fume will enter into the inside of the range hood through the smoke inlet 120 under the action of the negative pressure suction. Therefore, the second flow guide surface 323 needs to avoid being arranged above the smoke inlet 120, otherwise, the flow guide effect will be reduced under the influence of the airflow, and the setting mode of being reversely inclined to the first flow guide surface 322 is adopted.

[0059] Of course, in some embodiments, the inclined modes of the first flow guide surface 322 and the second flow guide surface 323 can also adopt other setting modes according to the overall structural features of the range hood, and the embodiment of the present application does not limit this.

[0060] In addition, the arc-shaped transition surface is arranged between the first flow guide surface 322 and the second flow guide surface 323 in the embodiment of the present application, which is a specific implementation mode of the bending surface structure of the flow guide surface 321, the liquid droplet 400 can smoothly flow from the first flow guide surface 322 to the second flow guide surface 323, and the flow guide effect of the protective cover 320 is ensured.

[0061] Further, in combination with Figure 2 , there is a gap between the second flow guide surface 323 and the flow guide plate 110, and this setting mode can avoid the liquid droplet 400 flowing into the space where the control box assembly 300 is located, and the flow guide effect of the protective cover 320 is ensured. If the surface of the second flow guide surface 323 is attached to the surface of the flow guide plate 110, there will be a small gap between the surface of the second flow guide surface 323 and the surface of the flow guide plate 110. When the liquid droplet 400 flows from the second flow guide surface 323 to the flow guide plate 110, under the action of the capillary phenomenon, the liquid droplet 400 may seep into the space where the control box assembly 300 is located along the gap between the surface of the second flow guide surface 323 and the surface of the flow guide plate 110. With the continuous accumulation of the liquid droplet 400 in the space where the control box assembly 300 is located, the liquid droplet 400 may seep into the inside of the control box, and cause erosion and damage to the electric control 330 in the inside of the control box.

[0062] In combination with Figure 2 , the protective cover 320 further includes the bottom surface 324 connected to the lower end of the flow guide surface 321, and the height of the end of the bottom surface 324 connected to the flow guide surface 321 is the lowest. This setting mode is also to avoid the liquid droplet 400 flowing into the inside of the control box along the outer surface of the protective cover 320, and causing erosion and damage to the electric control 330 in the inside of the control box. When the bottom surface 324 is arranged, the bottom surface 324 needs to be arranged in an upward inclination, otherwise, the liquid droplet 400 cannot drop from the lower end of the flow guide surface 321 to the flow guide plate 110, but may flow to the bottom surface 324 under the action of the surface tension of the liquid droplet 400. In order to avoid this situation and ensure the flow guide effect of the protective cover 320, this setting mode is adopted.

[0063] Further, in combination with Figures 2-4 The protective cover 320 further comprises a flow guide portion and a first lap portion 325, the flow guide surface 321 is arranged on the flow guide portion, the first lap portion 325 is connected with the upper end of the flow guide portion, and the first lap portion 325 is connected with the outer surface of the cabinet 210.
