[0040] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0041] like Figures 1 to 7 As shown, this embodiment of the present disclosure provides a range hood, including a cross-flow fan 13 and a light source assembly 20, wherein the cross-flow fan 13 can drive the light source assembly 20 to rotate. At this time, the light source assembly 20 can illuminate preset light beads and utilize the visual persistence effect of the human eye to display information such as time or the operating status of the range hood, thereby improving the overall aesthetics of the range hood.

[0042] like Figures 1 to 7As shown, this embodiment of the present disclosure provides a range hood including: a housing 10, a cross-flow fan 13, a light source assembly 20, a speed sensor, and a control device. The housing 10 has an installation area 12, and the side wall of the housing 10 corresponding to the installation area 12 has a transmission area 11. The cross-flow fan 13 is horizontally disposed in the installation area 12 along the length of the housing 10, and includes a cross-flow impeller 131. The light source assembly 20 includes a display circuit board 21 disposed around the periphery of the cross-flow impeller 131, and multiple LED beads 22 are disposed on the display circuit board 21, with each LED bead 22 capable of being individually lit or extinguished. The speed sensor is used to acquire the rotational speed of the cross-flow impeller 131. The control device is electrically connected to both the speed sensor and the light source assembly 20. The cross-flow fan 13 can drive the light source assembly 20 to rotate around the central axis of the cross-flow impeller 131, and the speed sensor can send a rotational speed signal of the cross-flow impeller 131 to the control device. The control device can control the LED beads 22 to be lit or extinguished according to the rotational speed signal.

[0043] Specifically, the cross-flow fan 13 also includes a drive motor 132, which is driven by the cross-flow impeller 131 to rotate the impeller 131 around its central axis. The installation area 12 is located on the side of the housing 10 closest to the user, and the cross-flow fan 13 is horizontally positioned within the installation area 12. A transmission plate is provided on the outer wall of the installation area 12 facing the user to form a transmission area 11, which isolates the installation area 12 from the external environment, thereby improving the overall aesthetics of the range hood and avoiding safety hazards.

[0044] When the range hood is turned on, the drive motor 132 drives the cross-flow impeller 131 to rotate circumferentially to extract cooking fumes from the environment. At the same time, the cross-flow impeller 131 drives the light source assembly 20 to rotate synchronously and rapidly. A speed sensor acquires the rotational speed of the cross-flow impeller 131 in real time and sends the speed signal to the control device. Upon receiving the speed signal, the control device determines the rotational speed of the light source assembly 20. When the rotational speed of the cross-flow impeller 131 exceeds a preset speed threshold, the control device activates a preset light bead. Thus, due to the persistence of vision, the user can view the information displayed by the light source assembly 20 through the transmission area 11.

[0045] This design ensures that users can view relevant information through the transmission area 11 while improving the overall aesthetics of the range hood. Furthermore, using the range hood provided in this application allows for full utilization of the space around the cross-flow impeller 131, resulting in a more compact internal structure.

[0046] In practical applications, the control device includes input modules such as touch panels or remote control modules. Users can input preset display information into the control device through touch panels or remote control modules. The control device then controls the lamp beads 22 to light up or turn off according to the preset display information and the rotation speed of the cross-flow impeller 131, so that the light source assembly 20 can display the preset display information.

[0047] like Figures 3 to 7 As shown, in some embodiments, the cross-flow impeller 131 includes blades 133, and the range hood also includes a mounting bracket 23. The mounting bracket 23 is fixedly mounted on the blades 133, and the display circuit board 21 can be fixedly mounted on the mounting bracket 23.

[0048] Specifically, one side of the mounting bracket 23 can be fixedly mounted on the outer side of the blade 133, and the display circuit board 21 can be fixedly mounted on the other side of the mounting bracket 23, so that the display circuit board 21 is fixedly mounted on the periphery of the cross-flow impeller 131. In this way, the blade 133 can drive the display circuit board 21 to rotate synchronously with the cross-flow impeller 131, making it easier for the control device to determine the rotation speed and position of the display circuit board 21 based on the rotation speed of the cross-flow impeller 131, thereby achieving more precise control of the display circuit board 21.

[0049] In practical applications, the blade 133 is generally quite long, meaning it can be installed in more locations. This allows the display device to be mounted on the blade 133, making it easier to adapt to the usage habits of different users.

[0050] Optionally, the cross-flow impeller 131 includes multiple blades 133, which are spaced apart around the central axis of the cross-flow impeller 131. The mounting bracket 23 can be simultaneously fixedly installed on the outer side of multiple adjacent blades 133 to improve the stability of the installation.

[0051] In some embodiments, the range hood includes a plurality of mounting brackets 23, and the two ends of the display circuit board 21 are respectively fixedly mounted on at least one mounting bracket 23.

[0052] Specifically, the display circuit board 21 is configured as a cuboid and is horizontally mounted on the blade 133 to accommodate more LEDs 22 along its length, thereby increasing the display area. At this time, the left end of the display circuit board 21 is fixedly mounted to the blade 133 by at least one mounting bracket 23, and the right end of the display circuit board 21 is also fixedly mounted to the blade 133 by at least one mounting bracket 23, to improve the stability of the display circuit board 21 installation.

[0053] Optionally, the length of the display circuit board 21 is greater than or equal to a preset length, and the middle part of the display circuit board 21 is mounted on at least one mounting bracket 23 to further improve the stability of the display circuit board 21 installation.

[0054] like Figure 6 and Figure 7 As shown, in some embodiments, the mounting bracket 23 includes a fixing surface facing the blade 133 and a mounting surface facing away from the blade 133. The fixing surface is provided with a first snap fastener to engage with the blade 133, and the mounting surface is provided with a second snap fastener to engage with the display circuit board 21.

[0055] Specifically, the mounting surface of the mounting bracket 23 is provided with a first latch, and the size and shape of the first latch correspond to the blade 133, so that the mounting bracket 23 can be snapped onto the blade 133 via the first latch. Similarly, the mounting surface of the mounting bracket 23 is provided with a second latch, and the size and shape of the second latch correspond to the display circuit board 21, so that the display circuit board 21 can be snapped onto the mounting bracket 23 via the second latch. This makes it easier for users to replace or maintain the display circuit board 21, improving the user experience.

[0056] like Figure 1 As shown, in some embodiments, the sidewalls of the housing 10 corresponding to the mounting area 12 are provided with one-way transparent glass to form a transmission area 11.

[0057] Specifically, a one-way transparent glass is fixedly installed on the side wall of the housing 10, and the size of the one-way transparent glass is larger than or equal to the size of the display circuit board 21. Thus, when the light source assembly 20 is on, the user can see the display information on the display circuit board 21 through the one-way transparent glass. When the light source assembly 20 is off, ambient light cannot pass through the one-way transparent glass to illuminate the interior of the installation area 12. This design allows the interior of the installation area 12 to be concealed, increasing the overall integration and maintaining the aesthetic harmony of the range hood.

[0058] like Figure 3 As shown, in some embodiments, the width of the display circuit board 21 is greater than or equal to half the width of the blade 133, and less than or equal to three times the width of the blade 133.

[0059] Specifically, the width of the display circuit board 21 is greater than or equal to half the width of the blade 133, allowing for more LEDs 22 to be arranged along the width of the display circuit board 21, thereby increasing the display area. Simultaneously, the width of the display circuit board 21 is less than or equal to three times the width of the blade 133, thus reducing the impact of the display circuit board 21 on airflow. For example, the width of the display circuit board 21 can be half, one, two, or three times the width of the blade 133.

[0060] like Figure 4 As shown, in some embodiments, the range hood includes a plurality of light source assemblies 20, and the plurality of light source assemblies 20 are arranged at intervals in a manner parallel to the central axis of the cross-flow impeller 131.

[0061] Specifically, multiple light source components 20 are arranged parallel to the central axis of the cross-flow impeller 131, and the distance between adjacent light source components 20 is greater than a preset distance. In this way, multiple display areas can be formed by multiple light source components 20, thereby further increasing the area of ​​the display area without making a single light source component 20 too large.

[0062] In some embodiments, the control device is electrically connected to a plurality of light source components 20 to individually control the lamp beads 22 of the plurality of light source components 20 to light up or turn off.

[0063] Specifically, the control device can individually control the LEDs 22 of multiple light source components 20 to light up or turn off, so that the multiple light source components 20 form multiple independent display areas. In this way, the control device can simultaneously display multiple display information to the user through different light source components 20, further improving the user experience.

[0064] In some embodiments, the range hood further includes a wireless charging transmitter and a wireless charging receiver. The wireless charging transmitter is disposed on the housing 10; the wireless charging receiver is disposed on the cross-flow impeller 131 and is electrically connected to the light source assembly 20; wherein the wireless charging transmitter can cooperate with the wireless charging receiver to supply power to the light source assembly 20.

[0065] Specifically, the range hood also includes a power supply device, which is electrically connected to the wireless charging transmitter. The light source assembly 20 also includes a power storage device, and the wireless charging receiver is electrically connected to the power storage device. In this way, the power supply device can drive the wireless charging transmitter to generate an alternating magnetic field, and the wireless charging receiver generates electrical energy under the influence of the alternating magnetic field and supplies power to the power storage device. After receiving electrical energy, the power storage device can supply power to the light source assembly 20. This reduces the wiring within the range hood, avoiding safety hazards and further improving the compactness of the various structures within the range hood.

[0066] like Figure 2 As shown, in some embodiments, the range hood includes a plurality of cross-flow impellers 131, and the plurality of cross-flow impellers 131 are horizontally arranged in the installation area 12 along the length direction of the housing 10; wherein, each cross-flow impeller 131 is provided with at least one light source assembly 20.

[0067] Specifically, multiple cross-flow impellers 131 are horizontally arranged along the length of the housing 10 in the mounting area 12, and speed sensors can acquire the rotational speed of each of the multiple cross-flow impellers 131. Simultaneously, each cross-flow impeller 131 is equipped with at least one light source assembly 20, and the control device is electrically connected to the light source assemblies 20 on each of the multiple cross-flow impellers 131. In this way, the control device can control the corresponding LED beads 22 of the light source assembly 20 to light up or turn off according to the rotational speed of each of the multiple cross-flow impellers 131, further improving the user experience.
