Description

Technical Field

[0001] The invention belongs to the technical field of blowing and lighting, and in particular relates to a roller blade fan and a lamp with the roller blade fan. Background Art

[0002] With the continuous development of smart homes, ceiling lamps, as indispensable lighting equipment in modern families, are constantly developing in the direction of diversification and intelligence in terms of functions and designs. In recent years, ceiling lamps with integrated fans have gradually emerged. Ceiling lamps not only provide lighting functions, but also enable air circulation to keep indoor air fresh and smooth. This integrated design not only saves space, but also improves indoor comfort, especially in summer or in environments with poor air circulation. It not only has lighting functions, but also provides users with a cool experience.

[0003] However, with the popularization of ceiling lamp fan products, new technical problems have also emerged. Typical ceiling lamp integrated fan products, such as the technology disclosed in announcement number CN220769746U, are usually designed as bladeless fans. The advantage of bladeless fans is that they have a simple structure and reduce the complexity of traditional fans, but they are also accompanied by some unique problems. In this design, a number of air outlet grilles are arranged in the air outlet, and the grilles cover each other to close the air outlet. When the fan is in a closed state for a long time in the autumn and winter seasons, the lighting function of the lamp is still turned on, but the fan does not run, resulting in a large amount of dust and dirt accumulating in the gaps between the air outlet grilles.

[0004] Since bladeless fans are usually fixed on the ceiling, they are relatively difficult to clean. When the fan is not used for a long time, the accumulated dust will fall with the opening of the grille, and may even be blown out with the air flow, causing indoor air pollution. This problem is particularly prominent during use, especially for those fans that are closed for a long time, where dust accumulates seriously and is difficult to clean.

DETAILED DESCRIPTION

[0028] like Figures 1 to 8As shown, a roller blade fan comprises a stopper unit 10 and a roller blade unit 20, wherein the stopper unit 10 and the roller blade unit 20 are movably connected and fixed by fasteners, the roller blade unit 20 has a roller blade 21 built therein, one end of the roller blade 21 is connected to a blade motor 22, the stopper unit 10 comprises a stopper side cover 11, an air outlet 111 is formed on the surface of the stopper side cover 11, and a movable stopper 12 is transversely connected to the air outlet 111, and the movable stopper 12 is connected to the air outlet 111. One end of the member 12 is connected to a stopper motor 13. When in use, the fan motor 22 is powered on to drive the roller fan blade 21. The roller fan blade 21 generates air circulation, i.e., wind force. The stopper motor 13 is powered on to control and adjust the swing of the movable stopper 12. The movable stopper 12 can control the wind direction of the air outlet 111 and close and open the air outlet 111. When the movable stopper 12 closes the air outlet 111, the movable stopper 12 forms the same horizontal plane with the stopper side cover 11. The stopper unit 10 and the roller fan blade unit 20 are fixed by a movable structure, and different stops and different roller fan blade units can be replaced to complete the air outlet connection.

[0029] During the specific implementation, the two ends of the movable stopper 12 are respectively connected to the swing arm 14, and the rear side of the movable stopper 12 is provided with an embedding rib 121. One end of the swing arm 14 is provided with a swing arm plug block 141 adapted to the embedding rib 121, and the swing arm plug block 141 is inserted into the end of the embedding rib 121. The two end surfaces of the embedding rib 121 are respectively provided with a first swing arm fixing hole 122, and the surface of the swing arm plug block 141 is provided with a second swing arm fixing hole 142. The first swing arm fixing hole 122 corresponds to the second swing arm fixing hole 142, and is connected and fixed to the second swing arm fixing hole 142 through a fastener passing through the first swing arm fixing hole 122, so that the two swing arms 14 are respectively fixedly connected to the two ends of the movable stopper 12, with a simple structure and convenient installation.

[0030] In a specific implementation, the swing arm 14 at one end is provided with a free movable end 143, and the swing arm 14 at the other end is provided with a driving end 144. The end of the blocking motor 13 facing the driving end 144 is provided with a motor shaft 131, and the motor shaft 131 is connected to the driving end 144. One end of the air outlet 111 is provided with a motor mounting position 15, and the blocking motor 13 is fixedly installed on the motor mounting position 15 by a fastener.

When in use, the baffle motor 13 is energized to drive the motor shaft 131 to rotate, thereby driving the swing arm 14 of the driving end 144 to rotate synchronously. The free movable end 143 swings in the movable through hole 16 with it as the axis, and controls the swing angle of the movable baffle 12 together with the driving end 144 to achieve left and right adjustment of the wind direction, and can realize closing and opening control of the air outlet 111 by swinging the movable baffle 12 to a horizontal position.

[0031] In a specific implementation, the roller fan blade unit 20 includes a lower shell 23 and an upper shell 24. The upper shell 24 is embedded in the lower shell 23. A number of shell through-pillars 231 are evenly arranged on the inner side of the lower shell 23. A number of shell through-holes 241 are evenly opened on the surface edge of the upper shell 24. The number of shell through-holes 241 corresponds to the number of shell through-pillars 231 one by one, and fasteners are passed through the shell through-holes 241 to connect and fix with the shell through-pillars 231, so that the upper shell 24 is fixedly embedded in the lower shell 23. The structure is simple, and the installation is convenient and stable.

[0032] In a specific implementation, the roller blade 21 is horizontally connected to the upper shell 24, a motor mounting portion 242 is provided on one side of the upper shell 24, and the blade motor 22 is fixedly mounted on the motor mounting portion 242 by a fastener, and a movable mounting position 243 is provided on the other side of the upper shell 24, and a movable wearer 25 is installed in the movable mounting position 243, and a motor drive end 211 is provided at one end of the roller blade 21 facing the blade motor 22, and the motor drive end 211 is connected to the blade motor 22. 21 is provided with a movable connecting end 212 at one end facing the movable wearer 25, and the movable connecting end 212 is connected to the movable wearer 25. When in use, the fan blade motor 22 drives the motor driving end 211 to rotate after being energized, thereby driving the roller fan blade 21 to rotate with a horizontal axis. The movable connecting end 212 realizes low-friction rotation support in the movable wearer 25, so that the roller fan blade 21 can maintain balance and coaxiality when running at high speed. The rotation of the roller fan blade 21 drives air circulation, forms strong wind force, and realizes the fan air outlet function.

[0033] During specific implementation, a side wall of the upper shell 24 is provided with a duct arc plate 244, which is an arc-shaped plate to match the rotation path of the roller fan blade 21, and is helpful to guide the wind flow to be discharged in a predetermined direction. An air outlet end 245 is correspondingly provided in the axial upward direction of the duct arc plate 244 for guiding the wind flow output. The other end of the duct arc plate 244 is an open wall surface, and the open wall surface connects the chamber of the upper shell 24 with the chamber of the lower shell 23, so that the chamber of the upper shell 24 and the chamber of the lower shell 23 form an air cavity, and the air outlet 111 is correspondingly connected to the air outlet end 245. When in use, the air in the air cavity can be blown out from the air outlet end 245 to the air outlet 111, thereby achieving a good ventilation effect.

[0034] During specific implementation, the bottom surface and side wall of the lower shell 23 are respectively provided with air inlet gap surfaces 232, and the bottom surface and side wall with the air inlet gap surface 232 are in the wind cavity, and the air inlet gap surface 232 of the bottom surface is sealed and engaged with the lower end of the air duct arc plate 244 of the upper shell 24. When in use, when the fan motor 22 drives the roller fan blade 21 to rotate, negative pressure suction is formed, driving air to enter from the air inlet gap surface 232 of the bottom surface and the side wall. After the air enters the wind cavity, under the guidance of the air duct arc plate 244, the air flows along the arc channel in the cavity, and is finally blown out from the air outlet end 245 and the air outlet 111. Due to the sealing and engaging design between the air duct arc plate 244 and the air inlet gap surface 232, air turbulence and backflow can be effectively reduced, and the flow rate and flow direction stability of the wind flow can be improved.

[0035] In a specific implementation, a heating element 26 is installed on the inner wall of the lower shell 23, and a heating element through-column 246 is symmetrically provided on the inner surface of the upper shell 24. A heating element through-column 261 is symmetrically provided on both sides of the heating element 26. The heating element through-column 261 is correspondingly sleeved on the outer side of the heating element through-column 246, and is connected and fixed to the heating element through-column 246 by fasteners passing through the heating element through-column 261. A plurality of heating gaps 262 are opened on the surface of the heating element 26. 62 corresponds to the air inlet gap surface 232 of the side wall. When in use, the heating element 26 starts to heat up after being energized, and its heat energy is conducted to the passing air through the heating gap 262. External air enters from the bottom surface and the air inlet gap surface 232 of the side wall, flows through the heating element 26 and the heating gap 262 area, and is heated. The heated air is sucked in by the roller fan blades 21, guided by the air duct arc plate 244, and efficiently blown out from the air outlet 111, thereby realizing the hot air output function.

[0036] In the specific implementation, the heating element 26 is made of graphene material, which has excellent electrical conductivity and thermal conductivity, high heating efficiency, fast heating speed, and can quickly generate heat in a short time to achieve efficient heating of the air. In addition, the heating element 26 can also be made of a metal heating tube structure, with a heating wire arranged inside the heating tube, and its outer shell is coated with a high-temperature resistant alloy material, which has good heat resistance and stability and is suitable for long-term continuous working scenes.

[0037] During the specific implementation, a plurality of first fixing penetrations 247 are respectively provided on both sides of the upper shell body 24, and a plurality of second fixing penetrations 112 are respectively provided on both sides of the baffle side cover 11. The plurality of first fixing penetrations 247 correspond to the plurality of second fixing penetrations 112 one by one, and are connected and fixed to the first fixing penetrations 247 by fasteners passing through the second fixing penetrations 112, so that the baffle unit 10 and the roller fan blade unit 20 are movably connected and fixed in position.

[0038] When implemented specifically, the movable baffle 12 is an integrated structure. The angle of the baffle can be adjusted by swinging the included angle between the movable baffle 12 and the baffle side cover 11. The angle change of the movable baffle 12 can adjust the air outlet direction. When the included angle between the movable baffle 12 and the baffle side cover 11 is 0 degrees, the movable baffle 12 is in a closed state with respect to the air outlet 111. When the movable baffle 12 is in a closed state with respect to the air outlet 111, the coverage area of ​​the movable baffle 12 is slightly smaller than the area of ​​the air outlet 111, so that a gap portion 17 is provided at the edges around the movable baffle 12 and the air outlet 111. The gap portion 17 can effectively guide the air circulation and prevent dust and debris in the air flow from accumulating at the joint surface of the movable baffle 12, thereby ensuring smooth and clean ventilation of the equipment during long-term use, thereby improving the durability and cleanliness of the equipment.

[0039] In a specific implementation, the movable baffle 12 and the air outlet 111 are both rectangular, elliptical or square in shape.

[0040] In a specific implementation, a display mounting portion 113 is provided at one end of the baffle side cover 11, and a display 18 is installed on the display mounting portion 113. When in use, the display 18 can display various working parameters, such as the warm air level, whether it is working, the air volume, and the type of light. The function display can be increased or decreased according to actual use. In addition, the display 18 can be a mechanical display or an electronic display.

[0041] like Figure 1 , 4As shown in Figure 9, a lamp with a roller blade fan includes a lamp body 30, which is installed on the ceiling by ceiling mounting to provide fixed support. The roller blade unit 20 and the baffle unit 10 of the roller blade fan are installed inside the lamp body 30 to ensure its stable operation. An illumination light source 31 is installed on the inner side of the lamp body 30. When in use, the roller blade fan drives the roller blade 21 to rotate through the blade motor 22 to generate air flow, effectively ventilate or adjust the air quality in the room. The baffle unit 10 has a wind direction control function to adjust the direction of the wind flow or close the air outlet as needed, thereby further optimizing the indoor air circulation effect. The illumination light source 31 provides efficient and uniform lighting, which not only meets the lighting needs, but also avoids the space occupied by multiple devices, thereby improving space utilization.

[0042] During specific implementation, the surface of the upper shell 24 is provided with an air inlet surface 248, and the air inlet surface 248 can absorb the heat generated by the lamp body 30 into the wind cavity. When the roller fan is installed on the lamp body, the lamp body 30 will generate a large amount of heat during lighting operation. When the heat cannot be volatilized, it will damage the internal components of the lamp body 30 and affect the service life. The heat can be neutralized in the wind cavity and then blown out from the air outlet of the baffle unit 10, which can also extend the service life of the lamp body.
