Description

Technical Field

[0001] The utility model relates to the technical field of combining a fan with a light source, in particular to a bladeless fan lamp. Background Art

[0002] The existing ceiling fan lamp includes a ceiling fan part and a lamp part arranged below the ceiling fan part. The ceiling fan lamp part includes a turntable driven by a motor, a plurality of fan blades arranged on the turntable, a synchronization structure arranged between the turntable and the fan blades, and a lamp plate arranged below the turntable. When the fan stops working, under the combined action of centrifugal force and the synchronization structure, the plurality of fan blades are synchronously unfolded to enable the fan to work normally. When the fan stops working, the fan blades are moved toward the rotating disk under the action of the rotary force of the recovery structure, and under the action of the positioning structure of the recovery structure, the inner edge of the fan blade is pressed against the outer edge of the rotating disk. The plurality of fan blades are connected head to tail to form a circle and stored on the back of the lamp part so as not to affect the overall appearance of the ceiling lamp. Since the centrifugal force is required to unfold the blades when the fan is working, this kind of fan lamp has special requirements on the structure of the blades, and thus it is not easy to meet the design requirements of efficient fanning. For this reason, some people have designed a bladeless fan lamp, that is, the blades are separated from the lamp, and a fan cover is provided, and the lamp is arranged around the fan cover. In this kind of bladeless fan lamp, since the lamp is arranged around the fan cover, the area of ​​the fan cover occupied by the lamp is large, which reduces the air outlet area of ​​the fan, thereby affecting the fan efficiency. Summary of the invention

[0003] The utility model aims to provide a bladeless fan lamp which can ensure the fanning efficiency of the fan.

[0004] The utility model is implemented as follows: it includes a motor, a fan blade disk, a fan cover, and a lamp. The shaft of the motor connected to the rotor axis is a tubular shaft. The fan cover includes a front cover and a rear cover. The front cover is connected to the rear cover, and the rear cover is connected to the shaft on the back of the motor stator. The fan blade disk is fixed in front of the motor stator, the front cover is located in front of the fan blade disk, the lamp is arranged in the middle part of the front cover, and the power line enters from the back of the shaft and passes through the hole of the shaft and is connected to the lamp.

[0005] During operation, the back end of the shaft is fixed at a set position, and the motor works to make the motor stator rotate relative to the shaft, driving the fan blade disk to rotate and fan the air forward, and the fanned wind is blown out from the front cover. Although the middle part of the front cover is blocked by the lamp, the area of ​​the middle part of the front cover is smaller than that of the surrounding areas of the front cover. Moreover, the wind is fanned out by the blades around the fan blade disk. Therefore, the amount of wind fanned out that is lost due to obstruction is small, thereby ensuring the fanning efficiency.

[0006] Compared with the prior art, the utility model has the advantage of ensuring the fanning efficiency of the fan. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0013] The utility model bladeless fan lamp is now described in further detail with reference to the accompanying drawings and embodiments:

[0014] like Figure 1 , 2 As shown in Figure 3, the utility model leafless fan lamp comprises a motor 1, a fan blade disc 2, a fan cover 3, and a lamp 4. The shaft 101 connected to the rotor axis of the motor 1 is a tubular shaft. The fan cover 3 comprises a front cover 301 and a rear cover 302. A hoop 303 is provided at the connection between the front cover 301 and the rear cover 302. The hoop 303 can be a lamp belt so as to decorate the fan cover 3 with lights. The rear cover 302 is connected to the rear connecting plate 5 on the shaft 101 on the back side of the motor stator 102. The fan blade disc 2 comprises a circular disc 201, blades 202 arranged around the circular disc 201, and the circular disc 201 of the fan blade disc 2 is provided. 01 is fixed in front of the motor stator 102, the front cover 301 is located in front of the fan blade disk 2 and fixed on the front connecting plate 6 in front of the motor stator 102, the front connecting plate 6 is connected to the shaft 101 (such as fixed to the shaft 101), the light source of the lamp 4 located in the middle of the front of the front cover 301 is fixed to the middle of the front of the front cover 301 by screws that pass through the front cover 301 and are screwed on the front connecting plate 6, the lampshade of the lamp 4 is buckled in the middle of the front end of the front cover 301 and covers the light source, the power cord enters from the back of the shaft 101 and passes through the hole of the shaft 101 and is connected to the lamp 4 so as to supply power and control signals to the lamp 4.

[0015] The fan blade disk 2 includes a circular disk 201 and blades 202 arranged around the circular disk 201. In this way, the blades 202 can adopt an optimal design and an optimal number to ensure the fanning efficiency.

[0016] Preferably, the front cover 301 includes a circular cover frame 3011 and a plurality of air guide blades 3012 arranged on the cover frame 3011. The plurality of air guide blades 3012 are evenly distributed on the circular cover frame 3011 in a spiral shape, so that the blown wind is blown out in a spiral shape to increase the wind speed and blowing volume.

[0017] During operation, the back end of the shaft 101 is fixed to the ceiling through a fixing seat 8 with a decorative cover 7. The motor 1 works to make the motor stator 102 rotate relative to the shaft 101, driving the fan blade disc 2 to rotate and fan the air forward. The fanned air is blown out from the front cover 301. At the same time, the lamp 4 in the middle of the front cover 301 can be controlled to work.

[0018] like Figure 4 As shown, the front cover 301 of the second embodiment includes a circular cover frame 3011, and a plurality of circular air guide rings 3013 arranged on the cover frame 3011. The circular air guide rings 3013 are in a trumpet shape, and the plurality of circular air guide rings 3013 are distributed in a ring-in-ring form. By using the trumpet-shaped circular air guide rings 3013, the wind blown out by the fan blade disc 2 is blown out in the form of channel wind, thereby enhancing the wind force of the wind.

[0019] like Figure 5 As shown, the front cover 301 of the third embodiment includes an inner annular frame 3014, an outer annular frame 3015, and a plurality of air guide plates 3016 radially connected between the inner annular frame 3014 and the outer annular frame 3015. The air guide plates 3016 are inclined so that the plate surface of the air guide plates 3016 forms an acute angle with the axis of the shaft 101. In this way, the wind blown out by the fan blade disc 2 is blown out in a spiral shape under the guidance of the air guide plates 3016, thereby enhancing the wind force of the wind.
