[0035] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:
[0036] See also Figures 1 to 7 The utility model provides a range hood, comprising a range hood body 1 , a box body 2 and a display module 3 .
[0037] The range hood body 1 has a sheet metal panel 11 with a through hole on the side facing the user. By placing the sheet metal panel 11 on the user-facing side of the range hood body 1, the display module 3 faces the user, making it easier for the user to operate the display module 3 when using the range hood.
[0038] The box body 2 is provided with a display hole. The user-facing side of the box body 2 is ultrasonically welded to the sheet metal panel 11. The display hole communicates with the through hole, and the diameter of the display hole is the same as that of the through hole. In this embodiment, ultrasonic welding of the box body 2 to the sheet metal panel 11 provides a more secure weld. Furthermore, ultrasonic welding does not affect the appearance of the sheet metal panel 11, enhancing the aesthetics of the range hood body 1.
[0039] The display module 3 is detachably mounted within the housing 2. The display module 3 includes a touch panel that passes through the display hole and is inserted into the through hole. Specifically, the display module 3 is detachably mounted within the housing 2 using screws. The touch panel passes through the display hole and is inserted into the through hole, with the touch panel facing the user. When using the range hood, the user controls the range hood by means of the touch panel.
[0040] The present invention mounts the display module 3 within the housing 2, which supports and protects the display module 3. Furthermore, the housing 2 is ultrasonically welded to the sheet metal panel 11, allowing the display module 3 to be more securely mounted on the range hood body 1, thereby preventing the display module 3 from falling off. When using the range hood, the user controls the range hood by touching the touch panel.
[0041] Based on the above examples, please refer to Figure 1 and Figure 2 The range hood body 1 of the present invention also includes a cover plate 4 and a fixing plate 5. The top of the sheet metal panel 11 is provided with a mounting hole through which the box body 2 can pass. The cover plate 4 covers the mounting hole, and the box body 2 is fixed to the sheet metal panel 11 via the fixing plate 5. When installing the box body 2, the user first opens the cover plate 4, inserts the box body 2 through the mounting hole, and then places it into the range hood body 1. The touch panel is inserted into the through-hole, and the box body 2 is fixed to the sheet metal panel 11 via ultrasonic welding. Simultaneously, the box body 2 is again fixed to the sheet metal panel 11 via the fixing plate 5. The cover plate 4 is then closed over the mounting hole, allowing for quick installation of the box body 2.
[0042] Based on the above examples, please refer to Figure 3 and Figure 4The box body 2 of the present invention includes an upper shell 21, a lower shell 22, and a wire 23. The upper shell 21 and the lower shell 22 are detachably connected. The upper shell 21 defines the display hole, and the lower shell 22 defines a hole for the wire 23. The wire 23 is electrically connected to the display module 3 and can pass through the hole. Specifically, the upper shell 21 and the lower shell 22 are detachably connected by screws. By separating the upper shell 21 and the lower shell 22, the display module 3 can be fixedly installed in the box body 2, and the box body 2 supports and fixes the display module 3.
[0043] Based on the above examples, please refer to Figure 3 and Figure 4 The box body 2 of the present invention also includes a light-transmitting sheet 24. A mounting slot is provided on the top of the upper housing 21, communicating with the display aperture. The light-transmitting sheet 24 is removably mounted within the mounting slot.

The light-transmitting sheet 24 is removably mounted within the mounting slot via ultrasonic welding, securing the light-transmitting sheet 24 to the box body 2 more securely and preventing it from falling off when installed or touched by the user. By touching the light-transmitting sheet 24, the touch control portion is touched, enabling control of the corresponding function.
[0044] Based on the above examples, please refer to Figure 3 and Figure 5 The display module 3 of the present invention includes a switch circuit board 31, a display assembly 32, and a color film assembly 33. The display assembly 32 is mounted on the switch circuit board 31 and electrically connected to the wire 23. The color film assembly 33 is detachably mounted on top of the display assembly 32. Both the display assembly 32 and the color film assembly 33 are electrically connected to the switch circuit board 31. The color film assembly 33 includes the touch control portion. The switch circuit board 31 supports the display assembly 32 and the color film assembly 33, facilitating their installation. Specifically, the display assembly 32 is mounted on the switch circuit board 31 using screws. The display assembly 32 provides light and supports the color film assembly 33. The color film assembly 33 is detachably mounted on top of the display assembly 32 by adhesive bonding. When a user touches the touch control portion, the capacitance of the touch control portion changes, thereby controlling the corresponding function of the range hood.
[0045] Based on the above examples, please refer to Figure 7The display assembly 32 of the present invention includes a display housing 321 and an LED lamp 322. The display housing 321 is detachably mounted on the switch circuit board 31 and has a light guide channel. The LED lamp 322 is detachably mounted within the display housing 321, with the projection of the LED lamp 322 located within the light guide channel. Specifically, the display housing 321 is detachably mounted on the switch circuit board 31 by screws, and the LED lamp 322 is located in the middle of the display housing 321. When the user uses the range hood, after powering the switch circuit board 31 via the wire 23, the LED lamp 322 emits light. The light emitted by the LED lamp 322 illuminates the color film assembly 33, thereby illuminating the display module 3, making it easier for the user to touch the display. Through the touch control unit, the user can control the range hood.
[0046] Based on the above examples, please refer to Figure 3 The display assembly 32 of the present invention further includes a display circuit board 323 and lamp beads 324. The display circuit board 323 is detachably mounted within the display housing 321 and electrically connected to the switch circuit board 31. The display circuit board 323 is mounted on top of the LED lamp 322. The LED lamp 322 is electrically connected to the display circuit board 323. The projection of the LED lamp 322 is located in the middle of the display circuit board 323. The lamp beads 324 are detachably mounted on the edge of the display circuit board 323. Through the arrangement of the display circuit board 323 and the lamp beads 324, the display circuit board 323 is detachably mounted above the LED lamp 322 by bonding. During use, when the display circuit board 323 is powered on, the lamp beads 324 light up, thereby brightening the color film assembly 33.
[0047] Based on the above examples, please refer to Figure 7 The color film assembly 33 of the present invention includes a protective film 331 , a conductive film 332 , a color filter film 333 and a light leakage film 334 .
[0048] The protective film 331, conductive film 332, color filter film 333, and light leakage film 334 overlap in sequence from top to bottom. The light leakage film 334 is removably mounted on the display housing 321. Light emitted by the LED lamp 322 can pass through the light leakage film 334 via the light guide channel. In this embodiment, the conductive film 332 is provided with multiple touch areas with different functions. When a user touches a corresponding touch area, the corresponding conductor on the conductive film 332 produces a change in capacitance, thereby controlling the corresponding function of the range hood. The protective film 331 protects the conductive film 332, the color filter film 333 filters the light transmitted by the LED lamp 322 to form the color controlled by the user, and the light leakage film 334 blocks light outside the light guide channel.
[0049] Meanwhile, the diameter of the color film assembly 33 is 5cm-8cm, and the protective film 331 is brown or gray. The brown or gray protective film 331 transmits softer light, preventing external light from interfering with the display of the display device.
[0050] Based on the above examples, please refer to Figure 7 The protective film 331 , the conductive film 332 , the color filter film 333 and the light leakage film 334 of the present invention are of the same size.
[0051] The protective film 331 is a transparent protective film 331, the conductive film 332 is a transparent conductive film 332, the color filter film 333 is a color filter film 333, and the light leakage film 334 has a light-transmitting area and a light-shielding area. The light-transmitting area is located above the light-guiding channel and the projection of the lamp beads 324, and the light-shielding area is located at the edge of the light leakage film 334. During use, the color filter film 333 filters the light emitted by the lamp beads 324, so that when the lamp beads 324 and the LED lamps 322 are respectively turned on, the light emitted by the lamp beads 324 and the LED lamps 322 respectively pass through the light-transmitting area, and the light-shielding area blocks the light that deviates from the light-transmitting area, thereby making the display area of the display device clearer.
[0052] Based on the above examples, please refer to Figure 6 and Figure 7The color filter assembly 33 of the present invention also includes a flexible board 335. Both the switch circuit board 31 and the display circuit board 323 are provided with mounting channels. The mounting end of the flexible board 335 is detachably connected to the color filter assembly 33, and the free end of the flexible board 335 passes through the mounting channel and is detachably mounted to the bottom of the switch circuit board 31. By providing mounting channels on both the switch circuit board 31 and the display circuit board 323, the user can easily install the display device. In this embodiment, the flexible board 335 is an FPC. The upper end of the flexible board 335 is detachably connected to the light-shielding area of the light-leaking film 334 by bonding, or the upper end of the flexible board 335 passes through through-holes in the color filter 333 and the light-leaking film 334 and is detachably connected to the bottom of the conductive film 332 by bonding. The lower end of the flexible board 335 passes through the mounting channel and is mounted on the bottom of the switch circuit board 31 by bonding, thereby tightly fitting the color film assembly 33, the display assembly 32 and the switch circuit board 31 together, preventing the color film assembly 33 or the display assembly 32 from becoming loose when the user is using the range hood.
[0053] Furthermore, a spring is installed within the lower housing 22 of the present invention, with its ends connected to the lower housing 22 and the switch circuit board 31. In this embodiment, four springs are provided, mounted on four sides of the lower housing 22. The addition of springs at the four corners of the lower housing 22 allows the switch circuit board 31 to rest tightly against the upper cover and light-transmitting sheet 24, thereby ensuring better touch sensitivity when the user is using the display device.
