[0002] The present application relates to a fan lamp, belonging to the technical field of household appliances. Background Art
[0003] Nowadays, people's demands for indoor air quality are becoming increasingly stringent, leading to an increasing number of indoor ventilation devices, such as air conditioners, traditional axial-flow fans, and bladeless fan lamps. However, as these ventilation devices become more commonplace, they are also becoming increasingly problematic. For example, while air conditioners provide cooling and ventilation, the air they produce can often make people feel uncomfortable, especially during seasonal changes or when temperatures fluctuate significantly between morning and evening. Traditional axial-flow fans, however, have been gradually replaced due to their limited airflow range and safety concerns.
[0004] Existing bladeless fan lamps, the latest alternative to traditional axial-flow fans, are limited by their frame structure, resulting in short air ducts that prevent effective airflow. This results in a low wind speed, making the user feel a weak wind and significantly impacting the user experience. Furthermore, when the fan speed reaches a certain level, the noise level increases, compromising the user experience.
[0005] In view of this, it is indeed necessary to improve the existing fan lamp to solve the above problems. Summary of the Invention

[0027] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.
[0028] Referring to Figure 1 , this application discloses a fan light 100 comprising a housing assembly 1, a fan assembly 2, and a light source assembly 3. The fan assembly 2 is housed within the housing assembly 1, while the light source assembly 3 is secured to the bottom of the housing assembly 1, completely concealing the fan assembly 2. This improves user safety and prevents injury from accidental contact during use.
[0029] As shown in Figures 2 and 4 , the housing assembly 1 includes an upper shell 11 and a lower shell 12. The upper shell 11 is provided with an air inlet 110. A wind cavity 10 is formed between the upper shell 11 and the lower shell 12. An air outlet 120 is formed on the periphery of the lower shell 12. The air inlet 110, the wind cavity 10, and the air outlet 120 are interconnected. In other words, the air inlet 110, the wind cavity 10, and the air outlet 120 form the fan lamp 100. After air enters the wind cavity 10 through the air inlet 110, it is discharged through the air outlet 120.
[0030] Specifically, the fan assembly 2 is housed within the air cavity 10 and includes a motor assembly 21 and an impeller 22 disposed on the lower housing 12. The motor assembly 21 is connected to the impeller 22 to drive the impeller 22 to rotate. When the motor assembly 21 drives the impeller 22 to rotate, external air is driven into the air cavity 10 through the air inlet 110 and then discharged through the air outlet 120, forming a cycle.
[0031] As shown in Figure 3 , the fan light 100 also includes a deflector plate 4, which is arranged around the outer periphery of the lower shell 12 and, together with the lower shell 12, forms the air outlet 120. The thickness of the deflector plate 4 gradually increases or decreases in the direction of air flow at the air outlet 120, forming a first inclined surface 41 on the side of the deflector plate 4 facing the lower shell 12. This allows the inclination of the deflector plate 4 to control the air flow direction, providing a guiding effect. Furthermore, experimental testing has shown that the fan light 100 with the deflector plate 4 exhibits significantly less noise compared to a fan light without the deflector plate 4.
[0032] In this embodiment, the lower shell 12 is provided with a peripheral edge 121 corresponding to the deflector 4. The side of the peripheral edge 121 facing the deflector 4 forms a second inclined surface 1211. The air outlet 120 is formed between the first inclined surface 41 and the second inclined surface 1211. In other words, by adjusting the inclination ratio of the first inclined surface 41 and the second inclined surface 1211, the airflow velocity can be effectively increased and noise can be further reduced while achieving the guiding function of the deflector 4. Of course, the first inclined surface 41 and the second inclined surface 1211 are inclined in the same direction, so that they cooperate with each other to effectively increase the airflow velocity.
[0033] Specifically, referring to Figure 5 , in the air outlet direction at the air outlet 120, the vertical distance between the upper and lower surfaces of the deflector 4 is defined as the height of the deflector 4, the vertical distance between the upper and lower surfaces of the impeller 22 is defined as the height of the impeller 22, and the height of the deflector 4 accounts for 10% to 40% of the height of the impeller 22. The plane on which the height of the deflector 4 lies is defined as the first reference plane 40, and the angle α between the first inclined surface 41 and the first reference plane 40 is 5° to 15°. Experiments have shown that when the height and inclination angle of the deflector 4 are within this range, the air outlet and noise reduction effects are optimal.
[0034] Conversely, in the airflow direction at the air outlet 120, the vertical distance between the upper and lower surfaces of the surrounding edge 121 is defined as the height of the surrounding edge 121, and the height of the surrounding edge 121 is 8-25 mm. The plane on which the height of the surrounding edge 121 lies is defined as the second reference plane 1210, and the angle β between the second inclined surface 1211 and the second reference plane 1210 is 0.5° to 5°. Experiments have shown that when the height and inclination angle of the surrounding edge 121 are within this range, it better cooperates with the deflector 4 to enhance airflow and noise reduction.
[0035] The deflector 4 is fixed to the inner wall of the upper shell 11 and forms an airflow channel with the surrounding edge 121. The airflow channel is connected to the air cavity 10. The air outlet 120 is formed at the end of the airflow channel away from the air cavity 10. The deflector 4 is detachably fixed to the inner wall of the upper shell 11. The fixing method is not limited, as long as the deflector 4 is securely fixed.
[0036] Optionally, the deflector 4 is integrally formed with the upper shell 11. In this way, only a mold needs to be designed during production, which can reduce production costs. In this embodiment, the deflector 4 is provided as a separate component to ensure that the air outlet effect is optimal.
[0037] The lower shell 12 further includes a supporting portion 122 for supporting the fan assembly 2 and an extension portion 123 connecting the supporting portion 122 and the surrounding edge 121. The upper surface of the extension portion 123 is higher than the upper surface of the supporting portion 122, so that the extension portion 123 is arc-shaped as a whole.
[0038] The fan light 100 also includes a plurality of baffles 5, each spaced apart on the outer extension 123. An air outlet channel 50 is formed between two adjacent baffles 5, connecting the air cavity 10 and the air outlet 120. Alternatively, an air outlet channel is formed between the impeller 22 and the upper housing 11, and the plurality of baffles 5 divide the air outlet channel into multiple air outlet channels 50. The provision of the baffles 5 further increases wind speed.
[0039] Specifically, the baffle 5 comprises a first baffle wall 51 and a second baffle wall 52 which are arranged opposite to each other, and the first baffle wall 51 and the second baffle wall 52 are inclined in the same direction but at different angles, thereby ensuring a further increase in the air outlet speed.
[0040] To sum up, the fan lamp 100 of the present application sets a guide plate 4 on the outer periphery of the lower shell 12, so that the air outlet 120 is formed between the lower shell 12 and the guide plate 4, and then sets the side of the guide plate 4 facing the lower shell 12 as a first inclined surface 41 to control the air outlet direction; at the same time, the lower shell 12 is provided with a surrounding edge 121 corresponding to the guide plate 4, and the side of the surrounding edge 121 facing the guide plate 4 forms a second inclined surface 1211, and the air outlet 120 is formed between the first inclined surface 41 and the second inclined surface 1211. In this way, an air flow channel is formed through the surrounding edge 121 and the guide plate 4 to further increase the wind speed and reduce noise.
[0041] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
