These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0026] like Figure 1 and Figure 2 As shown, the present invention provides an embodiment of a ceiling-mounted ventilation and lighting integrated device. The ventilation and lighting integrated device is usually installed in the suspended ceiling of the kitchen and bathroom in a ceiling-mounted manner, and is composed of a panel 1, a shell 2 (including a cover plate 21, a bottom shell 22 and an external exhaust port 23, etc.), a lighting fixture 5, an exhaust fan assembly 3 and a control circuit board 4, etc., and has two basic functions of ventilation and lighting.

[0027] In this embodiment, the housing 2 of the ventilation and lighting integrated device is provided with a snap-fit ​​structure and is mounted on the ceiling by snap-fitting.

[0028] In this embodiment, a lighting fixture 5 is installed on the panel 1, and an internal circulation air outlet 11 is provided. A gap is reserved between the cover plate 21 and the panel 1, and an air inlet 24 is provided on the cover plate 21. The external air outlet 23 is provided on the bottom or side wall of the bottom shell 22, thereby forming a first air duct from the gap - air inlet 24 - exhaust fan assembly 3 - external air outlet 23. In this way, when the ventilation function is turned on, air enters the air inlet 24 from the gap between the cover plate 21 and the panel 1, and then is discharged outdoors through the exhaust fan assembly 3, the external air outlet 23 and the exhaust duct connected to the external air outlet 23. This function can remove moisture in the bathroom or smoke in the kitchen, etc. In this embodiment, the lighting fixture 5 is provided on the panel. The lighting fixture 5 adopts energy-saving lamps such as flat-panel LEDs.

[0029] In this embodiment, the following optional functions are also included:

[0030] 1. Emergency induction night light function. This function is realized by adding a night light control module 6. In this embodiment, the night light control module 6 and the control circuit board 4 are installed together. The night light control module 6 is composed of a human body sensing sensor 61, an energy storage unit 62 and a charging circuit 63. The charging circuit 63 is connected to the control circuit board 4 to charge the energy storage unit 62; the night light control module 6 provides a night light lighting function when the human body sensing sensor 61 is triggered. The night light lighting function can continue to work through the power supply of the energy storage unit of the night light control module when the power is temporarily cut off.

[0031] Preferably, the energy storage unit 62 can be composed of a single lithium battery, or multiple lithium batteries connected in series, or multiple lithium batteries connected in parallel, to meet the required energy storage requirements and output voltage requirements. For example, two 18650 lithium batteries connected in parallel can provide an output voltage of 3.7V and a capacity of 5000mAh.

[0032] Night lighting provides low-light illumination through a dedicated night light (a low-power LED lighting lamp, whose power is usually between 1W and 3W).

[0033] Preferably, a night light is arranged on the panel.

[0034] Preferably, a night light is disposed on the housing 2 to provide dim lighting through a gap between the panel 1 and the housing 2 .

[0035] Preferably, the human body sensing sensor 61 is a microwave radar. Microwave radar sensing is mainly used to detect obvious moving objects, and the sensing distance is relatively long, which can reach 6-15 meters, and is not affected by the ambient temperature. Microwave radar can be installed in a hidden manner without affecting the appearance.

[0036] 2. Background music playback function. This function is realized by the built-in Bluetooth music module 7. In this embodiment, the Bluetooth music module 7 is directly installed in the bottom shell 22. In this embodiment, the Bluetooth music module 7 adopts a +5V power supply and is powered by the control circuit board 4. The Bluetooth music module 7 is installed inside the shell 2, and its speaker can be installed on the cover plate 21 or the side wall of the first air duct. The Bluetooth music module 7 is installed in a built-in concealed manner through this structural method, which does not affect the overall appearance of the exhaust lighting, the panel structure design, and the equipment installation. The Bluetooth music module 7 is started when the power is turned on, and Bluetooth connection and music playback can be performed through terminals such as mobile phones.

[0037] In this embodiment, the Bluetooth music module 7 draws power from the control circuit board 4, and the Bluetooth music module 7 does not work when the main power supply of the ventilation and lighting integrated device is cut off.

[0038] The night lighting function and background music playback of this device can enhance the comfort of the home environment.

[0039] 3. Cold air function. This function is realized by setting a second air duct connected from the exhaust fan assembly 3 to the panel 1. When the cold air function is turned on, under the action of the exhaust fan, air enters from the air inlet, passes through the first air duct - exhaust fan - second air duct, and is blown out from the internal circulation air outlet 11 of the panel 1, realizing the circulation convection of indoor air.

[0040] 4. Hot air function: Based on the cold air function, this function adds a heating component such as a PTC heating ceramic sheet 8 to the second air duct to heat the air passing through the second air duct and then blow it out from the internal circulation air outlet 11 of the panel.

[0041] Preferably, the exhaust lighting lamp is provided with two fans and two independent air ducts, wherein one fan is connected to the external exhaust port to realize the exhaust function; the other fan is connected to the internal circulation port to realize the blowing function, and then combined with the heating component to realize the hot air function. The cold air function and the hot air mode are common functions. Those skilled in the art can set the position and structure of the exhaust fan component, the air inlet, the external exhaust port, the internal circulation port, the first air duct, the second air duct, the heating component, etc. according to the external dimensions and installation method of the exhaust lighting lamp. Here, the specific installation position of each component is not further explained.
