Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a fan lamp. Background Art

[0002] A fan lamp is a device that combines lighting and fan functions. For aesthetics and to reduce dust accumulation on the fan blades, the fan blades of the fan lamp are usually configured to be rotatable relative to the blade disc. When the fan function is needed, the fan blades rotate relative to the blade disc under the action of centrifugal force and extend out of the blade disc. When the fan function is not needed, the fan blades rotate relative to the blade disc in the opposite direction under the action of the elastic resetting member and fold onto the blade disc.

[0003] To ensure the realization of the opening and closing function of the fan blades, a limiting member is usually provided on the side of the blade disc facing away from the fan blades. The limiting member is connected to the fan blades and rotates synchronously to provide an installation or connection point for the elastic resetting member. At the same time, a limiting structure is provided on the side of the blade disc facing the fan blades to limit the rotation angle of the fan blades relative to the blade disc. However, this structure makes the structure of the blade disc relatively complex, and it is necessary to install the fan blades and the limiting member on both sides of the blade disc respectively, which is inconvenient for assembly and the structure is not compact enough.

[0041] In order to more clearly understand the above objects, features and advantages of the present invention, the solutions of the present invention will be further described below. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0042] In the following description, many specific details are set forth in order to fully understand the present invention, but the present invention can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present invention, rather than all the embodiments.

[0043] Referring to Figures 1 to 11 As shown, a kind of fan lamp provided by some embodiments of the present invention includes a blower disk 1, a blower 2, a driving member 7, a limiting member 3 and an elastic reset member 4.

[0044] Among them, the blower 2 is arranged on the blower disk 1 and is rotatably connected to the blower disk 1; the driving member 7 is connected to the blower disk 1 and is configured to drive the blower disk 1 to rotate and drive the blower 2 to unfold relative to the blower disk 1 to unfold the blower 2. Specifically, when the fan function needs to be used, the driving member 7 drives the blower disk 1 to rotate. During the rotation of the blower disk 1, a centrifugal force is generated. The blower 2 is affected by the centrifugal force and rotates relative to the blower disk 1, that is, the blower 2 is thrown out in the direction away from the center of the blower disk 1 under the action of the centrifugal force to unfold the blower 2; after the blower 2 unfolds relative to the blower disk 1, during the continuous rotation of the blower disk 1, the blower 2 is affected by the centrifugal force and remains in the unfolded state and rotates synchronously with the blower disk 1.

[0045] Exemplarily, the driving member 7 can be a driving mechanism such as a motor. The driving member 7 can be connected to the central part of the blower disk 1 to drive the blower disk 1 to rotate by using a driving mechanism such as a motor; the blower 2 can be arranged at the edge part of the blower disk 1. The blower 2 is rotatably connected to the blower disk 1. During the rotation of the blower disk 1, the blower 2 will be affected by the centrifugal force generated by the rotation of the blower disk 1, so that the blower 2 rotates relative to the blower disk 1, thereby unfolding the blower 2.

[0046] The limiting member 3 is fixed on one side of the fan blade disk 1 facing the fan blade 2 and is arranged corresponding to the fan blade 2. A rotation limiting portion 21 is provided on the fan blade 2, and a limiting and cooperating portion 31 is provided on the limiting member 3. The rotation limiting portion 21 cooperates with the limiting and cooperating portion 31 to limit the rotation angle of the fan blade 2 on the fan blade disk 1. That is to say, by fixing the limiting member 3 on the fan blade disk 1 and arranging the limiting member 3 corresponding to the fan blade 2, the rotation angle of the fan blade 2 on the fan blade disk 1 is limited by using the limiting structure provided between the limiting member 3 and the fan blade 2, so that the fan blade 2 can rotate relative to the fan blade disk 1 within a certain angle range, thereby realizing the unfolding or folding movement of the fan blade 2. Specifically, the limiting member 3 can be fixed on the fan blade disk 1 by screws, or can be fixed on the fan blade disk 1 by means of clamping, bonding and other structures.

[0047] The elastic reset member 4 is connected between one of the fan blade disk 1 and the limiting member 3 and the fan blade 2 and is configured to drive the fan blade 2 to fold relative to the fan blade disk 1. That is to say, the elastic reset member 4 can be connected between the fan blade disk 1 and the fan blade 2, or according to design requirements, the elastic reset member 4 can be connected between the limiting member 3 and the fan blade 2. Specifically, the elastic reset member 4 can be a reset torsion spring or a reset tension spring and other structures.

[0048] During the process of the driving member 7 driving the fan blade disk 1 to rotate, the limiting member 3 rotates synchronously with the fan blade disk 1. The fan blade 2 rotates relative to the fan blade disk 1 under the action of centrifugal force and unfolds, causing the elastic reset member 4 connected between one of the fan blade disk 1 and the limiting member 3 and the fan blade 2 to deform and store elastic potential energy. In this way, when the driving member 7 stops driving, that is, after the driving member 7 stops providing the rotation function to the fan blade disk 1, the fan blade disk 1 will gradually decelerate to a stop. The centrifugal force generated by the rotation of the fan blade disk 1 will slowly decrease to disappear. The elastic reset member 4 releases the elastic potential energy and returns to the state before deformation, so that the fan blade 2 rotates reversely relative to the fan blade disk 1 under the elastic force of the elastic reset member 4 and resets, thereby realizing the function of driving the fan blade 2 to reset by using the elastic reset member 4, and making the fan blade 2 rotate relative to the fan blade disk 1 to the folded state.

[0049] With such a setting, the unfolding or folding of the fan blade 2 relative to the fan blade disk 1 is realized by the rotation of the fan blade 2 relative to the fan blade disk 1, that is, the opening and closing function of the fan blade 2 is realized.

[0050] The ceiling fan light provided by the embodiment of the present utility model is configured such that a limiting member 3 is provided on one side of the blade disc 1 facing the blade 2, and the limiting member 3 is fixed to the blade disc 1. Meanwhile, a rotational limiting portion 21 is provided on the blade 2, and a limiting and mating portion 31 corresponding to the rotational limiting portion 21 is provided on the limiting member 3. With such a configuration, the blade 2 and the limiting member 3 are installed on the same side of the blade disc 1, that is, the installation of the blade 2 and the limiting member 3 on the same side of the blade disc 1 is achieved, which is convenient for assembly and makes the structure of the ceiling fan light more compact. In addition, by providing the limiting and mating portion 31 on the limiting member 3, the structure of the blade disc 1 can be simplified, facilitating the machining of the blade disc 1.

[0051] It should be noted that, in order to enable the blade 2 to rotate relative to the blade disc 1, an installation hole may be formed in the blade 2, and a through hole corresponding to the installation hole is formed in the blade disc 1. The blade 2 is installed on the blade disc 1 by means of a screw 5 passing through the installation hole and the through hole and a nut 6 sleeved on the screw 5, and the blade 2 can rotate relative to the blade disc 1 with the axis line of the screw 5 as the axis. Of course, the rotational connection manner between the blade 2 and the blade disc 1 is not limited to the above description, and other means such as adding a bearing between the two can also be adopted to achieve the rotational connection between the blade 2 and the blade disc 1.

[0052] In some embodiments, referring to Figure 8 As shown, the limiting member 3 includes a bottom wall 32 and a surrounding wall 33 connected to the periphery of the bottom wall 32. The bottom wall 32 and the surrounding wall 33 together form a receiving cavity 34 with an open end, and the open end of the receiving cavity 34 faces the blade 2. The elastic reset member 4 is located in the receiving cavity 34. With such a configuration, the limiting member 3 provides an installation space for the installation of the elastic reset member 4, thus making good use of the inner region space of the limiting member 3 and making the structures such as the elastic reset member 4 and the limiting member 3 provided between the blade 2 and the blade disc 1 more compact. Specifically, the limiting member 3 can be configured as a disc-shaped structure.

[0053] Further, a limiting notch 35 extending along the circumferential direction of the circumferential wall 33 is formed on the circumferential wall 33 of the limiting member 3. The limiting notch 35 has a first abutting surface 351 and a second abutting surface 352 that are opposite to each other along the circumferential direction of the circumferential wall 33. The first abutting surface 351 and the second abutting surface 352 form a limiting and mating portion 31. The rotation limiting portion 21 is a limiting convex portion formed on the fan blade 2, and the limiting convex portion is limited within the region between the first abutting surface 351 and the second abutting surface 352. When the fan blade 2 is unfolded, the limiting convex portion abuts against the first abutting surface 351, and when the fan blade 2 is folded, the limiting convex portion abuts against the second abutting surface 352. That is to say, the limiting convex portion is limited within the limiting notch 35, and when the fan blade 2 rotates relative to the fan blade disc 1, the limiting convex portion can have a certain rotation angle range within the limiting notch 35 along the rotation direction of the fan blade 2. Specifically, when the fan blade 2 rotates relative to the fan blade disc 1, the limiting convex portion on the fan blade 2 rotates relative to the fan blade disc 1 within the region defined between the first abutting surface 351 and the second abutting surface 352, that is, the fan blade 2 rotates forward or backward relative to the fan blade disc 1 within the defined angle range, realizing the unfolding or folding action of the fan blade 2.

[0054] Referring to Figure 3 and Figure 4 As shown, it is a schematic structural diagram of the fan blade 2 in the unfolded state. When the fan function needs to be used, the driving member 7 drives the fan blade disc 1 to rotate. The rotating fan blade disc 1 applies a centrifugal force in the direction away from the center of the fan blade disc 1 to the fan blade 2, causing the fan blade 2 to rotate and unfold relative to the fan blade disc 1 until the limiting convex portion on the fan blade 2 abuts against and is limited by the first abutting surface 351 on the limiting member 3, so that the fan blade 2 cannot continue to rotate in the direction away from the center of the fan blade disc 1, and the relative position between the fan blade 2 and the fan blade disc 1 is kept stable, and the fan blade 2 remains in the unfolded state; Referring to Figure 1 and Figure 2 As shown, it is a schematic structural diagram of the fan blade 2 in the folded state. When the fan function needs to be turned off, the driving member 7 stops driving, that is, the driving member 7 stops providing rotational kinetic energy to the fan blade disc 1. The fan blade disc 1 gradually decelerates to a stop, and the centrifugal force slowly decreases until it disappears. The elastic force of the elastic reset member 4 overcomes the centrifugal force to reset the fan blade 2. The fan blade 2 is subjected to an elastic force in the direction towards the center of the fan blade disc 1 applied by the elastic reset member 4, causing the fan blade 2 to rotate reversely and reset relative to the fan blade disc 1 until the limiting convex portion on the fan blade 2 abuts against and is limited by the second abutting surface 352 on the limiting member 3, so that the fan blade 2 cannot continue to rotate in the direction towards the center of the fan blade disc 1, and the relative position between the fan blade 2 and the fan blade disc 1 is kept stable, and the fan blade 2 remains in the folded state.

[0055] In some embodiments, referring to Figure 3 and Figure 4As shown, the fan blade 2 includes a fan blade 2 body and a mounting post formed at one end of the fan blade 2 body. The fan blade 2 rotates relative to the fan blade disc 1 with the axis line of the mounting post as the axis. Specifically, the mounting post protrudes and extends relative to the fan blade 2 body in the direction towards the side where the fan blade disc 1 is located. An installation hole is provided at one end of the mounting post facing the fan blade disc 1, and a through hole corresponding to the installation hole is provided on the fan blade disc 1. A screw 5 is used to pass through the installation hole on the mounting post and the through hole on the fan blade disc 1, and a nut 6 is sleeved on the protruding end of the screw 5, so that the mounting post is rotationally connected to the fan blade disc 1 through the screw 5 and the nut 6.

[0056] Further, referring to Figures 1 to 4 As shown, a rotation limiting portion 21 is provided on the outer peripheral surface of the mounting post. The rotation limiting portion 21 can specifically be a limiting convex portion provided on the outer peripheral surface of the mounting post. During specific assembly, the mounting post is located in the inner region of the surrounding wall 33 of the limiting member 3, and the limiting convex portion provided on the outer peripheral surface of the mounting post extends to the limiting notch 35 formed on the surrounding wall 33, and can rotate within the region defined between the first abutting surface 351 and the second abutting surface 352 of the limiting notch 35 during the rotation of the fan blade 2 relative to the fan blade disc 1.

[0057] In some embodiments, referring to FIGS. 2, Figure 4 and Figure 8 As shown, the elastic reset member 4 is a reset torsion spring. A first torsion spring limiting portion 22 is provided on the fan blade 2, a second torsion spring limiting portion 11 is provided on the fan blade disc 1, and an avoidance notch 36 corresponding to the second torsion spring limiting portion 11 for the second torsion spring limiting portion 11 to pass through is provided on the limiting member 3. One end of the reset torsion spring is connected to the first torsion spring limiting portion 22, and the other end is connected to the second torsion spring limiting portion 11. By providing the avoidance notch 36 on the limiting member 3, the installation of the reset torsion spring between the fan blade 2 and the fan blade disc 1 is realized.

[0058] Specifically, referring to Figure 7 and Figure 11 As shown, a limiting slot is formed on the fan blade 2, and the limiting slot forms the first torsion spring limiting portion 22. One end of the reset torsion spring is limited in the limiting slot. During specific implementation, an installation groove can be provided on the side of the mounting post of the fan blade 2 facing the fan blade disc 1. Two circumferentially adjacent and spaced limiting ribs are provided on the inner groove wall of the installation groove, and a limiting slot is formed between the two limiting ribs. One end of the reset torsion spring is limited in the limiting slot to realize the connection between one end of the reset torsion spring and the fan blade 2.

[0059] Specifically, referring to Figure 5 、 Figure 6 、 Figure 9 and Figure 10As shown, on one side surface of the impeller disc 1 facing the impeller 2, there are raised limiting ribs formed. A limiting socket is formed between the limiting ribs and the impeller disc 1, and the limiting socket is formed as the second torsion spring limiting part 11. The other end of the return torsion spring is limited in the limiting socket. With such a setting, through simple operations such as stamping on the corresponding part of the impeller disc 1, the limiting rib structure can be formed on the impeller disc 1, with a simple structure and convenient forming; when assembling the return torsion spring, only need to insert the other end of the return torsion spring into the limiting socket formed between the limiting ribs and the impeller disc 1, with simple operation, saving time and effort.

[0060] In some other embodiments, the elastic return member 4 is a return torsion spring. The impeller 2 is provided with a first torsion spring limiting part 22, and the limiting member 3 is provided with a second torsion spring limiting part 11. One end of the return torsion spring is connected to the first torsion spring limiting part 22, and the other end is connected to the second torsion spring limiting part 11. With such a setting, it is realized to connect the return torsion spring between the limiting member 3 and the impeller 2. Compared with connecting the return torsion spring between the impeller disc 1 and the impeller 2, the structure of the impeller disc 1 can be simplified, and there is no need to open an avoidance notch 36 on the limiting member 3, making the installation structure of the return torsion spring more simplified.

[0061] In some embodiments, referring to Figure 8 As shown, on the side of the limiting member 3 facing away from the impeller disc 1, there is an installation convex part 37. Referring to Figure 5 and Figure 6 As shown, on the impeller disc 1, there are installation positioning holes 12 corresponding to the installation convex part 37. Referring to Figure 9 and Figure 10 As shown, the installation convex part 37 is inserted into the installation positioning hole 12. With such a setting, through the cooperation of the installation convex part 37 and the installation positioning hole 12, the installation and positioning of the limiting member 3 on the impeller disc 1 are realized. In order to ensure the installation and positioning effect and ensure that the limiting notch 35 on the limiting member 3 is exactly located at a position adapted to the rotation limiting part 21 on the impeller 2, both the installation convex part 37 and the installation positioning hole 12 can be set as asymmetric special-shaped structures.

[0062] Referring to Figure 8 As shown, on the side of the limiting member 3 facing away from the impeller disc 1, there is a screw post 38. Referring to Figure 5 and Figure 6 As shown, on the impeller disc 1, there are screw holes 13 corresponding to the screw post 38. Referring to Figure 9 and Figure 10 As shown, the limiting member 3 is fixed to the impeller disc 1 through a fastener passing through the screw post 38 and the screw hole 13. With such a setting, the installation and fixation of the limiting member 3 on the impeller disc 1 are realized. Specifically, the number of the screw post 38 and the corresponding screw hole 13 can be multiple, such as two, three, four, etc.

[0063] In some embodiments, referring to Figures 1 to 4As shown, the fan blade 2 is provided with a fan blade mounting hole 23, the limiting member 3 is provided with a first fan blade fixing hole 39 corresponding to the fan blade mounting hole 23, and the fan blade disc 1 is provided with a second fan blade fixing hole corresponding to the fan blade mounting hole 23. The fan blade 2 is mounted on the fan blade disc 1 through a screw 5 passing through the fan blade mounting hole 23, the first fan blade fixing hole 39, and the second fan blade fixing hole, and a nut 6 sleeved on the screw 5. With such a setting, the installation of the fan blade 2 on the fan blade disc 1 is realized, and the fan blade 2 can rotate relative to the fan blade disc 1 with the axis of the screw 5 as the axis.

[0064] It should be noted that for the solution where the limiting member 3 is provided with a mounting protrusion 37 and the fan blade disc 1 is provided with a mounting positioning hole 12 corresponding to the mounting protrusion 37, a first fan blade fixing hole 39 can be opened in the central area of the mounting protrusion 37, and the mounting positioning hole 12 can simultaneously serve as the second fan blade fixing hole.

[0065] In some embodiments, referring to Figure 1 and Figure 3 As shown, the elastic reset member 4 is a reset torsion spring. The reset torsion spring includes a torsion spring body arranged in a spiral shape and two torsion feet connected to both ends of the torsion spring body; the height direction of the torsion spring body is arranged parallel to the axial direction of the fan blade disc 1, and the screw 5 passes through the torsion spring body, and the torsion spring body is elastically supported between the fan blade 2 and the limiting member 3 along the axial direction of the fan blade disc 1.

[0066] With such a setting, it is realized that the reset torsion spring is elastically supported between the fan blade 2 and the limiting member 3 along the axial direction of the fan blade disc 1, so that the fan blade 2 and the limiting member 3 do not directly contact, thereby reducing the friction when the fan blade 2 rotates relative to the fan blade disc 1, improving the smoothness of the rotation of the fan blade 2, and reducing the noise generated by friction.

[0067] In some embodiments, referring to Figures 1 to 4 As shown, the number of the fan blades 2 is multiple, and the multiple fan blades 2 are arranged at intervals along the circumferential direction of the fan blade disc 1, and the multiple fan blades 2 are arranged independently of each other; the number of the limiting members 3 is multiple, and the multiple limiting members 3 are arranged at intervals along the circumferential direction of the fan blade disc 1 and are arranged in one-to-one correspondence with the multiple fan blades 2; the number of the elastic reset members 4 is multiple and is arranged in one-to-one correspondence with the multiple fan blades 2, and an elastic reset member 4 is connected between each fan blade 2 and the fan blade disc 1. With such a setting, the multiple fan blades 2 can rotate independently of each other, which is convenient for installation, maintenance and other operations on a single fan blade 2 on the fan blade disc 1.

[0068] Specifically, the number of the fan blades 2, the limiting members 3, and the elastic reset members 4 can all be three. The three fan blades 2 are arranged at intervals along the circumferential direction of the fan blade disc 1. Specifically, the three fan blades 2 can be arranged at intervals along the circumferential direction of the fan blade disc 1 at the edge portion of the fan blade disc 1. Correspondingly, the three limiting members 3 are fixedly arranged at intervals along the circumferential direction of the fan blade disc 1 at the edge portion of the fan blade disc 1 and are arranged in one-to-one correspondence with the three fan blades 2. The three elastic reset members 4 are all reset torsion springs. The three reset torsion springs are respectively installed on the three limiting members 3 and are respectively connected between the fan blade 2 and the fan blade disc 1 through the avoidance notches 36 on the corresponding limiting members 3. Of course, the number of the fan blades 2, the limiting members 3, and the elastic reset members 4 can also be other numbers, and the number of the fan blades 2, the limiting members 3, and the elastic reset members 4 is equal and they are arranged in one-to-one correspondence.

[0069] In some embodiments, referring to FIGS. 1 to Figure 4 As shown, the driving member 7 is a motor, and the motor is connected to the center of the fan blade disc 1 to drive the fan blade disc 1 to rotate through the motor. With such an arrangement, the motor can control the rotation and stop of the fan blade disc 1. When it is necessary to blow air with the fan lamp, the motor drives the fan blade disc 1 to rotate to unfold the fan blades 2, and the fan blades 2 drive the air to flow, which is convenient for the user to independently turn on and off the fan function of the fan lamp.

[0070] Specifically, the motor can be installed at the center of the fan blade disc 1 so that the motor can drive the fan blade disc 1 to rotate around its own axis after starting. The motor can be selected to be connected to the fan blade disc 1 by bolts. Specifically, motor mounting holes 14 can be provided on the fan blade disc 1, and the motor is installed on the fan blade disc 1 through bolts passing through the motor mounting holes 14. The number of the motor mounting holes 14 can be one or more. Of course, other connection methods such as snap connection and riveting can also be selected to connect with the fan blade disc 1.

[0071] Referring to Figures 1 to 4 As shown, for the fan lamp provided by the embodiment of the present invention, during specific assembly, first, the motor is fixed on the fan blade disc 1 with four screws 5; then the limiting members 3 are placed on the fan blade disc 1, and the limiting members 3 are fixed on the fan blade disc 1 with screws 5 and washers on the back of the fan blade disc 1. One end of the reset torsion spring is hooked at the second torsion spring limiting portion 11 formed on the fan blade disc 1, and the other end of the reset torsion spring is fixed at the first torsion spring limiting portion 22 formed on the fan blade 2, and the fan blade 2 presses the reset torsion spring. The fan blade 2 is fixed with a screw 5 through the fan blade mounting hole 23 on the fan blade 2, the first fan blade fixing hole 39 on the limiting member 3, and the second fan blade fixing hole on the fan blade disc 1 and is locked together with a nut 6 to fix one fan blade 2, and the other two fan blades 2 are fixed in the same way.

[0072] During specific use, referring to Figure 3As shown, when the blowing function of the fan light is turned on, the motor drives the fan blade disc 1 to rotate. As the fan blade disc 1 rotates, under the action of centrifugal force, the fan blades 2 overcome the torsion force of the return torsion spring and the three fan blades 2 are thrown out. When the limiting convex part on the fan blade 2 contacts the corresponding first abutting surface 351 on the limiting member 3, the fan blade 2 reaches the maximum extension angle, and the fan blade 2 maintains this angle to rotate and supply air.

[0073] When the blowing function of the fan light is turned off, refer to Figure 1 As shown, the motor stops providing rotational kinetic energy, the centrifugal force gradually decreases to disappear, and the torsion force of the return torsion spring overcomes the centrifugal force to reset the fan blade 2 until the limiting convex part on the fan blade 2 contacts the second abutting surface 352 on the limiting member 3, and the reset is completed. The fan blade 2 maintains the closed state.
