[0047] Reference Figures 1-10 For an embodiment of the gesture module 100 of the present application, the gesture module 100 is installed on the extractor hood, and functions such as turning on and off are realized by waving hands.

[0048] As shown in Figures 1-4 The gesture module 100 includes a sensor body 110, a light-transmitting sheet 120 and an elastic material 130.

[0049] The sensor body 110 is generally an infrared gesture sensor, which is internally provided with a light emitter and a light receiver.

[0050] The light-transmitting sheet 120 is arranged at the front end of the sensor body 110, and functions to protect the sensor body 110 and allow light to penetrate. The light-transmitting sheet 120 is generally transparent, and at least a part thereof is formed with a light-transmitting region through which the light emitted by the light emitter can directly penetrate to perform signal transmission. In the embodiment, the light-transmitting sheet 120 has a protruding structure 121, which forms the light-transmitting region.

[0051] The elastic material 130 is at least partially attached to the front side of the light-transmitting sheet 120. The elastic material 130 functions to seal and prevent oil fume from entering the sensor body 110 and affecting the performance of the sensor.

[0052] The light-transmitting sheet 120 or the sensor body 110 is provided with a limiting boss 122. As shown in Figure 4 In the embodiment, the limiting boss 122 is arranged on the light-transmitting sheet 120.

[0053] As shown in Figure 5 and Figure 6 When the gesture module 100 is assembled on the first assembly surface 200 (such as a metal surface) which is not transparent, the protruding structure 121 cooperates with the opening 210 on the first assembly surface 200, the limiting boss 122 abuts against the surface of the first assembly surface 200, and the elastic material 130 is compressed to the same height as the limiting boss 122.

[0054] The limiting boss 122 can ensure that the protruding structure 121 is assembled in the opening 210, and the consistency of the thickness of the protruding structure 121 through the opening 210 is avoided, so as to avoid instability caused by excessive compression of the front elastic material 130. The elastic material 130 is compressed to the same height as the limiting boss 122, which can ensure that the first assembly surface 200 is tightly combined to prevent oil fume from entering.

[0055] As shown in Figure 9 and Figure 10 When the gesture module 100 is assembled on the second assembly surface 300 (such as a glass surface) which is transparent, the protruding structure 121 abuts against the surface of the second assembly surface 300, and the elastic material 130 is compressed to the same height as the protruding structure 121, which can ensure that the second assembly surface 300 is tightly combined to prevent oil fume from entering.

[0056] The first assembly surface 200 which is not transparent can be a metal surface formed of metal material, a plastic surface formed of plastic material, etc., and the second assembly surface 300 which is transparent can be a glass surface formed of glass.

[0057] The gesture module 100 is universal in assembly on the non-hole 210 and the hole 210 assembly surfaces by adding the limiting boss 122 on the light-transmitting sheet 120 or the sensor body 110, has strong module structure compatibility, can adapt to assembly requirements of different materials, reduces manufacturing cost, and improves production efficiency.

[0058] In some embodiments of the present application, as shown in Figure 3 The front end surface of the sensor body 110 is provided with a stepped portion 111, the light-transmitting sheet 120 is arranged in the stepped portion 111, and the elastic material 130 is attached to the front side of the sensor body 110 and the light-transmitting sheet 120. Specifically, the shell of the sensor body 110 forms a recessed stepped structure at the front end surface, the stepped structure is matched with the size of the light-transmitting sheet 120, so that the light-transmitting sheet 120 can be embedded therein. After the light-transmitting sheet 120 is embedded in the stepped portion 111, the outer surface thereof is basically flush with the outer surface of the sensor body 110, thereby forming a smooth surface. The elastic material 130 covers the outer surfaces of the light-transmitting sheet 120 and the sensor body 110, forming a continuous sealing layer, further strengthening the sealing effect, effectively preventing oil fume from entering the inside of the sensor body 110 and affecting the performance thereof.

[0059] In some embodiments of the present application, as shown in Figure 4 The limiting boss 122 is arranged on the light-transmitting sheet 120 and is integrally formed with the light-transmitting sheet 120 by injection molding. The limiting boss 122 is integrally formed with the light-transmitting sheet 120, simplifying the structure of the gesture module 100 and reducing the number of parts. Further, the limiting boss 122 is provided with two, and the two limiting bosses 122 are respectively located on the left and right sides of the protruding structure 121, so that the protruding structure 121 is more stable in the hole 210 and is prevented from tilting, thereby ensuring stable work of the gesture module 100 in various environments.

[0060] In some embodiments of the present application, the height of the protruding structure 121 on the light-transmitting sheet 120 is higher than the height of the limiting boss 122, and the height difference therebetween is the same as the depth of the hole 210 on the first assembly surface 200 on which the gesture module 100 is installed. When the gesture module 100 is installed on the assembly surface, the protruding structure 121 can be completely inserted into the hole 210 and flush with the outer surface of the first assembly surface 200, thereby improving the appearance.

[0061] In some embodiments of the present application, the first assembly surface 200 is a metal surface, and the second assembly surface 300 is a glass surface. Specifically, the gesture module 100 can be installed on two different types of assembly surfaces: one is a non-transparent metal surface, and the other is a transparent glass surface. When installed on the metal surface, an opening 210 matching the protruding structure 121 on the light-transmitting sheet 120 needs to be made on the metal surface, and the gesture module 100 is installed by inserting the protruding structure 121 into the opening 210. When installed on the glass surface, since the glass itself is transparent, there is no need to make an opening 210, and the gesture module 100 can be directly attached to the glass surface.

[0062] In some embodiments of the present application, the elastic material 130 is a foamed material, silicone or rubber. The function of the elastic material 130 is to seal the gap between the gesture module 100 and the assembly surface, preventing pollutants such as oil fume from entering the module. Among them, the foamed material has good buffering and sealing performance, which can effectively absorb vibration and prevent dust from entering. Silicone and rubber have excellent high-temperature resistance and oil resistance, and can maintain stable performance in harsh environments. According to different application scenarios and needs, appropriate elastic material 130 can be selected.

[0063] The present application also provides an extractor hood comprising the above-mentioned gesture module 100, the extractor hood having a non-transparent first assembly surface 200, and the gesture module 100 being assembled on the first assembly surface 200.

[0064] Specifically, the metal shell of the extractor hood forms a non-transparent first assembly surface 200, an opening 210 matching the protruding structure 121 of the gesture module 100 is made on the first assembly surface 200, and then the inner part of the metal shell of the gesture module 100 is inserted into the opening 210 for installation. By waving the hand, the switch and the air volume of the extractor hood can be controlled.

[0065] Further, as shown in Figure 7 and Figure 8 The extractor hood further comprises a mounting seat 400, and the gesture module 100 is first fixed on the mounting seat 400, and then the mounting seat 400 is fixed on the metal shell of the extractor hood through the adapter fixing member 500. The gesture module 100 can be fixed on the mounting seat 400 by means of screws, buckles, etc., and the adapter fixing member 500 can also be fixed with the metal shell by means of screws, buckles, etc. This installation method makes the installation of the gesture module 100 more flexible and convenient, and can be adjusted according to different product design needs.

[0066] The present application also provides another extractor hood comprising the above-mentioned gesture module 100, the extractor hood having a transparent second assembly surface 300, and the gesture module 100 being assembled on the second assembly surface 300.

[0067] Specifically, the control panel of the range hood adopts transparent glass material, and the gesture module 100 is directly attached to the back of the glass panel. By waving the hand gesture, the functions such as the on-off switch and the air volume of the range hood can be controlled. Since the glass panel is transparent, it is not necessary to open the opening 210 on the panel, and the installation of the gesture module 100 is more simple and beautiful.

[0068] Further, as Figure 10 The range hood further comprises a mounting seat 400, the gesture module 100 is fixed on the mounting seat 400, the mounting seat 400 is provided with a supporting piece 600, and the supporting piece 600 is in abutment with the surface of the second assembly surface 300. The gesture module 100 is first fixed on the mounting seat 400, and then is in abutment with the back of the glass panel of the range hood through the supporting piece 600 on the mounting seat 400. Since the convex structure 121 of the gesture module 100 has a small area, the supporting piece 600 can assist the gesture module 100 to be more stably in abutment with the glass panel.

[0069] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit them; although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not make the corresponding technical solutions deviate from the spirit and scope of the technical solutions claimed by the present application.
