Description

Technical Field

[0001] The utility model relates to an indoor air conditioning device and a lighting device, in particular to a bladeless fan lamp. Background Art

[0002] The fan wheel of the bladeless fan lamp is hidden in the lamp housing, and an air outlet is provided at the lower part of the lamp housing. There are currently two types of air outlets, one with adjustable air outlet direction and the other with fixed air outlet direction. The bladeless fan lamp with fixed air outlet direction is disclosed in the patent document with publication number CN119508250A. The air outlet direction of this fan lamp cannot be adjusted according to user needs.

[0003] For air outlets with adjustable air flow direction, if the air outlet is circular, a hood is usually installed at the air outlet, and air guide blades are set on the hood. The air flow direction is adjusted by rotating the hood. If the air outlet is strip-shaped, swing blades are usually installed at the air outlet. The angle of the swing blades is changed by a motor or they swing back and forth to adjust the wind direction. Although these two methods can change the air outlet angle, the hood or swing blades often vibrate during operation, causing noise and trouble for users. Moreover, the rotating hood is only suitable for circular air outlets, and the swing blades are only suitable for relatively regular strip-shaped or square air outlets, and cannot be applied to special-shaped air outlets. Utility Model Content

A motion mechanism that can drive the diverter to move vertically relative to the air outlet is installed between the diverter and the shell. The vertical movement in this application refers to a direction that is perpendicular or approximately perpendicular to the central horizontal plane of the fan air outlet, and the inclination refers to a direction in which the angle formed with respect to the central horizontal plane of the fan air outlet is an acute angle or an obtuse angle.

[0009] As a further improvement of the present invention, the outer contour of the cross-section of the shell is triangular, and the shell can be made of aluminum profiles, hard plastic and other materials. The shell has an integrally formed first shell slope, a second shell slope, a first air guide wall located on the inner side of the first shell slope, a second air guide wall located on the inner side of the second shell slope, and a fixing part located between the first air guide wall and the second air guide wall. The air outlet is formed after the fixing part is partially cut and removed.

[0010] As a further improvement of the present invention, a first light source cavity opening downward is formed between the first shell slope and the first wind guide wall, and a second light source cavity opening downward is formed between the second shell slope and the second wind guide wall, and the light sources are installed in both the first light source cavity and the second light source cavity.

[0011] As a further improvement of the present invention, a first light-transmitting cover is installed at the opening of the first light source cavity, and a second light-transmitting cover is installed at the opening of the second light source cavity.

The diverter has a large cross-section and is not affected by the air outlet and will not vibrate, thus solving the noise problem of the air outlet. Because the diverter moves vertically relative to the air outlet, it is not restricted by the shape of the air outlet and can adapt to relatively regular air outlets such as circular, strip, and square air outlets, as well as various special-shaped air outlets such as polygonal, elliptical, and wavy air outlets, making the shape setting of the air outlet more flexible.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0027] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0028] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 8 A fan lamp that adjusts the air outlet direction in a vertical manner includes a shell 1 and a light source 11 installed on the shell 1, a fan duct 12 is provided in the shell 1, the shell 1 is provided with an air inlet 121 connected to the air inlet end of the fan duct 12 and an air outlet 122 connected to the air outlet end of the fan duct 12, a diverter 2 is installed at the air outlet 122, and at least one inclined air guide surface is provided on the top of the diverter 2, a fan air outlet duct is formed between the air guide surface and the side wall of the air outlet 122, and a motion mechanism that can drive the diverter 2 to move vertically relative to the air outlet is installed between the diverter 2 and the shell 1.

[0030] Driven by the motion mechanism, the diverter 2 can move vertically relative to the air outlet 122, changing the shape between the air guide surface and the side wall of the air outlet 122, thereby changing the direction of the air outlet and achieving wind direction adjustment. The diverter is extruded from aluminum alloy or hard plastic, has a large cross-section, and will not vibrate due to the influence of the air outlet, thus solving the noise problem of the air outlet. In particular, since the diverter 2 moves vertically relative to the air outlet 122, it is not restricted by the shape of the air outlet 122 and can adapt to relatively regular circular, strip, and square air outlets, as well as various special-shaped air outlets such as polygonal, elliptical, and wavy air outlets, making the shape setting of the air outlet more flexible, as long as the shape of the diverter 2 is adapted to the shape of the air outlet 122.

[0031] In this embodiment, the outer contour of the cross section of the housing 1 is triangular, and comprises an integrally formed first housing slope 1a, a second housing slope 1b, a first air guide wall 13 located on the inner side of the first housing slope 1a, a second air guide wall 14 located on the inner side of the second housing slope 1b, and a fixing portion 15 located between the first air guide wall 13 and the second air guide wall 14. The fixing portion 15 is partially cut away to form the air outlet 122. The remaining fixing portion 15 serves to fix other components on the one hand and to strengthen the strength of the housing 1 on the other hand. A decorative cover 111 is mounted on the lower end of the housing 1 corresponding to the fixing portion 15. Plugs 5 are mounted on both ends of the housing 1. The plugs 5 are provided with sealing portions 51 corresponding to the fan duct 12. After assembly, the two ends of the fan duct 12 are in close contact with the sealing portion 51 to form a seal. Sealant may also be added to the contact portion between the two to improve the sealing performance.

[0032] The airflow in the fan duct 12 can be generated in a variety of ways. In this embodiment, the first way is to install a wind wheel 4 in the fan duct 12. The second way is to install a fan 401 at one end or both ends of the fan duct 12, so that the fan 401 is located between the air inlet 121 and the air inlet end of the fan duct 12. Of course, an external fan can also be used to introduce the airflow into the fan duct 12 through a pipe.

[0033] For the first method, the wind wheel 4 is long and runs through the entire fan duct 12. A wind wheel motor 41 for driving it to rotate is installed at one end or both ends of the wind wheel 4. Specifically, a rotating shaft 42 is provided at both ends of the wind wheel 4. A first rotating shaft seat 43 is fixed to the fixing part 15 on one side of the air outlet 122 by screws, and a second rotating shaft seat 44 is fixed to the fixing part 15 on the other side by screws. The rotating shaft 42 at one end of the wind wheel 4 is installed on the first rotating shaft seat 43 through a bearing, and the rotating shaft 42 at the other end is installed on the second rotating shaft seat 44 through a bearing. The wind wheel motor 41 is installed on the second rotating shaft seat 44. The rotating shaft 42 at one end of the wind wheel 4 is the rotating shaft of the wind wheel motor 41. Similarly, the wind wheel motor can also be installed on the first rotating shaft seat 43. At this time, the rotating shaft 42 at the other end of the wind wheel 4 is the rotating shaft of the wind wheel motor, and a shaft hole 45 for inserting the rotating shaft of the wind wheel motor 41 can be provided on the wind wheel 4. For this structure, the air inlet 121 is located on the side of one side of the shell 1, and is composed of a number of strip-shaped or circular air inlet holes 110 set on the side of one side of the shell 1. The air inlet 121 can also be a rectangular opening with an enlarged area. A cover with air holes can be installed at the rectangular opening, and a filter net can be set on the inside of the cover plate. The filter net is cleaned regularly to protect the wind wheel 4.

[0034] In the second method, a common small axial fan (such as the heat dissipation fan in a computer mainframe in the prior art) is used as the fan. In this structure, the air inlet can be located on the plugs 5 at both ends of the housing 1, or on the side of the housing 1 near the end. The small axial fan is fixed to the fixing portion 15 with screws. Similarly, a filter can be installed inside the plugs 5.

[0035] In this embodiment, the air outlet 122 is strip-shaped, and the cross-section of the diverter 2 is triangular, having a diverter bottom surface 2a, a first air-guiding slope 2b, and a second air-guiding slope 2c. The first air-guiding slope 2b and the second air-guiding slope 2c are the aforementioned air-guiding surfaces. A first air outlet duct 21 is formed between the first air-guiding slope 2b and one sidewall of the air outlet 122, and a second air outlet duct 22 is formed between the second air-guiding slope 2c and the other sidewall of the air outlet 122. The shape of the diverter bottom surface 2a has no effect on performance and can be flexibly set according to the shape. A light source cavity can also be set on the diverter bottom surface 2a and a light source can be installed. The first air guide slope 2b and the second air guide slope 2c will affect the air outlet direction. It is necessary to set the inclination angle between the end of the first air guide slope 2b and the end of the side wall on one side of the air outlet 122, as well as the inclination angle between the second air guide slope 2c and the end of the side wall on the other side of the air outlet 122 according to the designed air outlet angle, so that the air outlet directions of the first air outlet 21 and the second air outlet duct 22 are different, thereby generating an uneven airflow effect on both sides of the fan lamp.

[0036] In this embodiment, the second air guide wall 14 is composed of a transverse portion 141, a longitudinal portion 142 and an arcuate portion 143 located between the transverse portion 141 and the longitudinal portion 142. The transverse portion 141 is connected to the second shell inclined surface 1b, and the longitudinal portion 142 is connected to the fixed portion 15. The upper end of the longitudinal portion 142 is inclined inward, so that the connection between the longitudinal portion 142 and the arcuate portion 143 forms an inwardly extending pointed airflow dividing line. When the airflow flows through the airflow dividing line, most of the airflow is divided in a pointed shape, flows downward along the longitudinal portion 142, and is finally blown out from the air outlet 122. A small part of the airflow flows into the fan duct 12 again along the arcuate portion 143, reducing the vortex effect of the fan duct.

[0037] In this embodiment, a first light source cavity 16 opening downward is formed between the first shell slope 1a and the first air guide wall 13, and a second light source cavity 17 opening downward is formed between the second shell slope 1b and the second air guide wall 14. The light source 11 is installed in both the first light source cavity 16 and the second light source cavity 17. A first light-transmitting cover 161 is installed at the opening of the first light source cavity 16, and a second light-transmitting cover 171 is installed at the opening of the second light source cavity 17.

[0038] The light source 11 can be an LED light board fixed to the top of the first light source cavity 16 and the second light source cavity 17 by gluing or screws, or a light board slot can be provided in the first light source cavity 16 and the second light source cavity 17, and the LED light board is plugged into the light board slot. In this embodiment, the lower end inner wall of the first light source cavity 16 (i.e., the end of the first shell inclined surface 1a and the first air guide wall 13) is provided with a first card slot, and the lower end inner wall of the second light source cavity 17 (i.e., the end of the second shell inclined surface 1b and the second air guide wall 14) is provided with a second card slot. The side wall of the first light-transmitting cover 161 is inserted into the first card slot, and the side wall of the second light-transmitting cover 171 is inserted into the second card slot. In addition, it can be arranged that when the wind wheel 4 is closed, the diverter 2 moves upward so that the bottom surface 2a of the diverter is flush with the bottom of the first light-transmitting cover 161 and the second light-transmitting cover 171, and the diverter 2 closes the first air outlet 21 and the second air outlet 22, so that the wind wheel 4 is hidden in the shell 1 to improve the overall aesthetics.

[0039] The cam 33 is provided with a screw rod 33 and a guide rod 32 arranged in parallel. The outer wall of the guide rod 32 is a smooth surface, and the outer wall of the screw rod 33 has an external thread. An adjustment motor 34 is installed at one end of the screw rod 33 to drive it to rotate. A slider 311 is provided at the upper end of the support rod 31. The slider 311 is provided with a guide hole 312 and a threaded hole 313. The guide rod 32 is located in the guide hole 312, and the screw rod 33 is located in the threaded hole 313. The adjustment motor 34 rotates forward or reverse, and the slider 311 is driven to slide along the guide rod 32 toward or away from the air outlet 122 through the threaded cooperation between the threaded hole 313 and the screw rod 33, thereby changing the shape of the first air outlet 21 and the second air outlet 22 to achieve the purpose of changing the wind direction.

[0040] The adjusting motor 34 is fixed on the top of the guide seat 3, and the output shaft of the adjusting motor 34 is coaxial with the screw rod 33, or the screw rod 33 can be a part of the output shaft of the adjusting motor 34. The rotation of the adjusting motor 34 drives the screw rod 33 to rotate forward or reverse. A retaining ring is installed between the two ends of the screw rod 33 and the guide seat 3, so that the screw rod 33 can only rotate circumferentially but not move axially. Bearings can also be installed between the two ends of the screw rod 33 and the guide seat 3 to make the rotation smoother.

[0041] As a further improvement of the present invention, the movement mechanism also includes a limit block 35 fixedly installed on the fixed part 15, the limit block 35 has a connecting part 36, and a clamping part 37 protruding upward on one side of the connecting part 36, and a clamping hole 38 passing through the upper and lower ends is provided on one side of the clamping part 37. After assembly, the upper surface of the connecting part 36 is fixedly installed on the lower end of the fixed part 15, and the support rod 31 is located in the clamping hole 38, ensuring that the support rod 31 moves vertically up and down in the clamping hole 38, reducing the left and right shaking of the diverter 2 during the lifting process and improving stability.

[0042] The ends of the diverter 2 and the support rod 31 can be fixedly connected using screws or other means to prevent relative rotation between the ends of the diverter 2 and the support rod 31. Alternatively, a hinged connection using a hinge shaft and a reaming hole can be used to allow relative rotation between the ends of the diverter 2 and the support rod 31, allowing the user to manually adjust the angle of the diverter 2 to change the airflow direction. Alternatively, a motor can be installed between the ends of the diverter 2 and the support rod 31, and the rotation of the motor drives the diverter 2 to swing, achieving dynamic wind direction adjustment.

[0043] As a further improvement of the present invention, a hanging groove 19 for connecting to a hanging rod 18 is provided between the tops of the first shell inclined surface 1a and the second shell inclined surface 1b, so that the fan light can be hung on the ceiling through the hanging rod 18.

[0044] In this embodiment, when the diverter 2 moves vertically downward, the distance between the side wall of the diverter 2 and the side wall of the air outlet 122 increases, so that the openings of the first air outlet 21 and the second air outlet 22 become larger. Figure 3 As shown, the wind blown out from the first air outlet 21 and the second air outlet 22 flows outward and diffuses on both sides of the diverter 2; and when the diverter 2 moves vertically upward, the distance between the side wall of the diverter 2 and the side wall of the air outlet 122 decreases, making the openings of the first air outlet 21 and the second air outlet 22 smaller, as shown in FIG. Figure 7 As shown, the air blown out from the first and second air outlet ducts 21, 22 flows downward and inward, allowing users to adjust the desired air outlet direction as needed, improving user comfort. In the present invention, the wind rotor motor 4 is configured with multiple operating gears, each corresponding to a different speed of the wind rotor motor 4, thereby varying the air output. When the power of the wind rotor motor 4 remains constant, reducing the area of ​​the first and second air outlet ducts 21, 22 will increase the air flow rate, while increasing the area will reduce the air flow rate, resulting in a stronger or softer wind sensation.
