Description

Fan assembly and fan lamp

Technical Field

The application belongs to the technical field of household appliances, and particularly relates to a fan assembly and a fan lamp.

Background

The ceiling fan is fixedly installed on a ceiling, has a better heat relieving effect, and can provide a cool environment for a user. In order to increase the use function, some ceiling fans are integrated with lamps, so that the fan lamp with the blowing function and the lighting function is formed. However, some ceiling fans or fan lamps use flat blades, which do not stir air well when rotating, and thus wind power is insufficient.

In addition, the fan blades of some ceiling fans or fan lamps can be folded, so that the fan blades can shield dust and impurities from entering the ceiling fans or the fan lamps in a non-working state to influence the work. However, adjacent blades of the ceiling fan or the fan lamp overlap and contact with each other, so that during the starting or stopping process, the adjacent blades are easily rubbed or collided, thereby generating a large noise and easily damaging the blades.

The embodiments of the present application are described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 1-14, a fan assembly 100 is disclosed in an embodiment of the present application, the disclosed fan assembly 100 including fan blades 110 and a drive mechanism 120.

The fan blades 110 are members for pushing air in the fan assembly 100, and rotate around the central axis P of the fan assembly 100 at a high speed under the driving action of the driving mechanism 120, so as to push ambient air to flow, thereby achieving blowing. In order to increase the wind power and improve the blowing effect, the structure of the fan blade 110 is newly designed in the embodiment of the present application, and compared with some straight fan blades 110, the fan blade has a better blowing effect.

Referring to fig. 3 to 7, the fan blade 110 includes an inner edge 111 and an outer edge 112, and the inner edge 111 and the outer edge 112 are disposed opposite to each other in a width direction of the fan blade 110. When the fan blade 110 rotates, the inner edge 111 is located in front and the outer edge 112 is located in back along the rotation direction of the fan blade 110. With the fan blades 110 in the unfolded state, the inner edge 111 extends gradually obliquely in the first direction from one end close to the central axis P toward one end away from the central axis P. It should be noted that, when the fan assembly 100 is in the installation state, the upward direction is the first direction. When the fan assembly 100 is in the installed condition, the inner edge 111 is relatively lower in the area near the middle of the fan assembly 100 and relatively higher in the area near the edge of the fan assembly 100. Likewise, the outer edge 112 extends gradually obliquely in the first direction from an end close to the central axis P toward an end distant from the central axis P. The first direction here is an upward direction in the installed state of the fan assembly 100. When the fan assembly 100 is in the installed condition, the outer edge 112 is relatively low in the area near the middle of the fan assembly 100 and relatively high in the area near the edges of the fan assembly 100. Based on this, the entire fan blade 110 is made to exhibit a relatively low area near the middle of the fan assembly 100 and a relatively high area near the edge of the fan assembly 100. Therefore, in the folding process of the fan blades 110, the end of the next fan blade 110 far away from the central axis P does not contact with the end of the previous fan blade 110 near the central axis P, so that the phenomena of friction, collision and the like between the two adjacent fan blades 110 are effectively prevented, and the problems of noise and fan blade 110 damage caused by the friction and collision between the two adjacent fan blades 110 are effectively avoided.

An arc surface 113 is connected between the inner edge 111 and the outer edge 112, and the arc surface 113 extends from the inner edge 111 to the outer edge 112 in a direction opposite to the first direction, that is, the arc surface 113 extends from the inner edge 111 to the outer edge 112 in an outward bending manner, so that the inner edge 111 and the outer edge 112 are connected by the arc surface 113. Based on above-mentioned setting, the inboard face of arcwall face 113 is the lower place in the front, so, when actuating mechanism 120 drove flabellum 110 rotatory, the air striking was at the medial surface of arcwall face 113 to under the pushing action of the medial surface of arcwall face 113, the direction flows to the lower place in the front, thereby realizes blowing. Therefore, the inner side surface of the arc-shaped surface 113 has a certain air-holding effect, so that more air can be pushed to flow, the better air stirring effect is achieved, and the wind power of the fan assembly 100 is improved.

In order to increase the wind power of the fan assembly 100, a plurality of blades 110 may be further disposed on the driving mechanism 120, and the plurality of blades 110 may be simultaneously driven to rotate at a high speed by the driving mechanism 120, so that each blade 110 has a function of taking in wind, thereby increasing the wind power of the fan assembly 100.

The driving mechanism 120 is a power component of the fan assembly 100, and is used for driving the fan blades 110 to rotate at a high speed so as to achieve blowing. Alternatively, the driving mechanism 120 may include a driving motor, a power output end of the driving motor is in transmission connection with the rotating disc 140 so as to drive the rotating disc 140 to rotate, and the fan blades 110 are disposed on the rotating disc 140 and can rotate along with the rotating disc 140. In some embodiments, the driving mechanism 120 is provided with a plurality of fan blades 110 that can be unfolded or folded relative to the driving mechanism 120, and when the fan assembly 100 is in an operating state, the fan blades 110 can be unfolded relative to the driving mechanism 120 so as to agitate air and achieve blowing; when the fan assembly 100 is in the non-operating state, the fan blades 110 can be folded relative to the driving mechanism 120, so that the space occupied by the fan assembly 100 can be reduced, and the fan assembly 100 can be partially shielded by the fan blades 110, thereby effectively preventing dust, impurities and the like from entering the fan assembly 100 to a certain extent and affecting the normal operation of the fan assembly 100.

In order to prevent the adjacent blades 110 from contacting and colliding, in the embodiment of the present application, when the blades 110 are in the retracted state, a gap M is disposed between the two adjacent blades 110, at this time, in an initial stage of the blades 110 being unfolded relative to the driving mechanism 120, due to the existence of the gap M, the two adjacent blades 110 are not touched, so that the problem of blade 110 damage caused by abrasion and collision between the two adjacent blades 110 is effectively alleviated.

Based on the above arrangement, the fan blades 110 in the embodiment of the present application can be regarded as a space curved surface structure, and the space curved surface structure can be set according to the characteristics of the fluid flow, so as to ensure that the space curved surface structure has a better air stirring effect to improve the wind power, and the adjacent fan blades 110 can be separated from each other to ensure that the fan blades 110 are intact, and reduce the noise.

Referring to fig. 4, in some embodiments, the inner edge 111 forms a concave space, and when the fan blades 110 are in the folded state, an end of the latter fan blade 110 away from the central axis P is at least partially located in the concave space of the former fan blade 110, so that adjacent fan blades 110 are arranged in a staggered manner. Based on the above arrangement, under the condition that the fan blades 110 are in the folding state, the two adjacent fan blades 110 are arranged in an inner staggered manner, so that the plurality of fan blades 110 are effectively arranged, the effective space on the driving mechanism 120 is fully utilized, the space occupied by the fan blades 110 on the driving mechanism 120 is reduced to a certain extent, and the whole size of the fan assembly 100 is smaller under the condition of the same size and the same number of fan blades 110.

In some embodiments, when the leaves 110 are in the collapsed state, a gap M is formed between the outer edge 112 of the next leaf 110 and the inner edge 111 of the previous leaf 110. It should be noted here that, since the inner edge 111 and the outer edge 112 are both space curves, the gap M may be a first gap formed by the inner edge 111 and the outer edge 112 being spaced apart from each other in the radial direction of the fan assembly 100, or may be a second gap formed by the inner edge 111 and the outer edge 112 being spaced apart from each other in the up-down direction of the fan assembly 100, and of course, the gap M may include both the first gap and the second gap. Based on the above arrangement, the two adjacent fan blades 110 are completely spaced, that is, the two adjacent fan blades 110 are not touched in the unfolding or folding process of the fan blades 110, so that the completeness of the fan blades 110 is ensured, and the noise is reduced.

In some embodiments, when the leaves 110 are in the collapsed state, a projection of the outer edge 112 of the next leaf 110 in the first direction has a gap M with a projection of the inner edge 111 of the previous leaf 110 in the first direction. That is, the outer edge 112 of the next fan blade 110 and the inner edge 111 of the previous fan blade 110 are arranged in parallel, and a gap M is formed between the outer edge 112 and the inner edge 111 of the next fan blade 110, so that the two adjacent fan blades 110 are not overlapped, and thus the free expansion or folding of each fan blade 110 can be ensured without mutual influence, and the fan blades 110 are not touched.

Referring to fig. 5, 7 and 9, in some embodiments, fan blades 110 are rotatably unfolded or rotatably folded about an axis of rotation Q relative to drive mechanism 120. Alternatively, the driving mechanism 120 may include a rotating disk 140, the fan blade 110 may be rotatably disposed on the rotating disk 140, and a rotation axis Q may be formed between the fan blade 110 and the rotating disk 140, so that the fan blade 110 can rotate around the rotation axis Q. The inner edge 111 has a first position point 1111, the outer edge 112 has a second position point 1121, and the rotation radii of the first position point 1111 and the second position point 1121 with respect to the rotation axis Q are equal, and in the first direction, the horizontal plane where the first position point 1111 is located is higher than the horizontal plane where the second position point 1121 is located. Since the inner edge 111 can be regarded as a space curve formed by splicing a plurality of first position points 1111 and the outer edge 112 can be regarded as a space curve formed by splicing a plurality of second position points 1121, in a state that the fan assembly 100 is installed, a position point on the whole space curve of the inner edge 111 is higher than a corresponding position point on the whole space curve of the outer edge 112, so that the fan blade 110 as a whole tends to be higher inside and lower outside. Based on this, when the fan blades 110 rotate, since the inner edge 111 is located at the front and the outer edge 112 is located at the rear, the fan blades 110 have a stronger air stirring effect, so that the wind force of the fan assembly 100 can be increased.

Referring to fig. 3 and 7, in some embodiments, fan blade 110 has a leading end 116 distal from central axis P and a trailing end 117 proximal to central axis P, trailing end 117 being rotationally coupled to drive mechanism 120; the width of the fan blade 110 gradually increases from the tail end 117 to the head end 116 of the fan blade 110. When the fan blades 110 are in the unfolded state, because the head end 116 of the fan blades 110 is far away from the central axis P, and the tail end 117 is close to the central axis P, when the fan blades 110 rotate, the centrifugal action on the head end 116 is large, and the centrifugal action on the tail end 117 is small, so that the fan blades 110 are gradually widened from the tail end 117 to the head end 116, the strength of the whole fan blades 110 can be improved, the fan blades 110 can bear large centrifugal action without deformation or damage, and the normal use of the fan assembly 100 is ensured. In addition, the linear velocity of the head end 116 is higher, and the linear velocity of the tail end 117 is lower, so that the fan blades 110 are gradually widened from the tail end 117 to the head end 116, and more air can generate a greater flow velocity along with the fan blades 110 to a certain extent, so as to increase the wind power of the fan assembly 100.

In other embodiments, the fan blades 110 may have the same width from the trailing end 117 to the leading end 116. This arrangement provides more uniformity to the fan blade 110 and facilitates the manufacture of the fan blade 110.

In other embodiments, it may also be that the width of the head end 116 is greater than the width of the area away from the head end 116. The fan blade 110 mainly widens the head end 116, so that on one hand, the strength of the head end 116 can be improved, the head end 116 of the fan blade 110 can bear larger centrifugal action without deformation or damage, the normal use of the fan blade 110 is ensured, on the other hand, the effect of stirring air of the head end 116 can be improved, and therefore more air can generate larger flowing speed along with the head end 116 of the fan blade 110, and further the wind power of the fan assembly 100 can be improved.

Further, referring to fig. 7, the width of the fan blade 110 gradually increases from the position between the head end 116 and the tail end 117 to the head end 116. Therefore, the strength of the head end 116 area of the fan blade 110 can be ensured, the head end 116 area of the fan blade 110 can bear larger centrifugal action without deformation or damage, and meanwhile, the air stirring effect of the head end 116 area can be improved, so that more air can generate larger flow speed along with the head end 116 area of the fan blade 110, and the wind power of the fan assembly 100 is further improved.

With continued reference to fig. 3 and 7, in some embodiments, the fan blade 110 has a leading end 116 distal from the central axis P, a trailing end 117 proximal to the central axis P, and a middle region 118 between the leading end 116 and the trailing end 117, wherein the inner edge 111 has a greater curvature in the middle region 118 than the inner edge 111 at the leading end 116 and the trailing end 117. The curvature of the middle region 118 of the inner edge 111 is relatively large, so that the middle region 118 of the inner edge 111 forms the concave space, so as to achieve the inner staggered arrangement of the two adjacent fan blades 110. It should be noted that, because the curvature of the middle region 118 is relatively large, the bending degree of the fan blade 110 at the middle region 118 is relatively large, and the bending degree of the head end 116 and the tail end 117 is relatively small, so that the head end 116 of the fan blade 110 is bent towards the central axis P, so as to facilitate the staggered arrangement between two adjacent fan blades 110, and further reduce the space occupied by the fan blade 110 on the driving mechanism 120.

In order to make the shape of the fan blade 110 relatively uniform without abrupt change, in the embodiment of the present invention, the curvature of the outer edge 112 in the middle region 118 is larger than the curvature of the outer edge 112 at the head end 116 and the tail end 117. Since the curvature of the tail end 117 of the outer edge 112 is relatively small, so that it is adapted to the curvature of the outer edge of the rotating disc 140 of the driving mechanism 120, when the fan blades 110 are folded, the fan blades 110 can be completely folded into the rotating disc 140, and the outer edge 112 is located at the outer edge of the rotating disc 140, so that the space on the rotating disc 140 can be effectively utilized to a certain extent.

In some embodiments, the inner edge 111 has a peak distance relative to a line connecting an end of the fan blade 110 away from the central axis P and an end near the central axis P at a position between the end of the fan blade 110 away from the central axis P and the end near the central axis P. It is understood that a point at a certain position between both end portions of the fan blade 110 is a peak point, and a distance from the peak point to a connecting line between both end portions of the fan blade 110 is a peak distance, and at this time, the distance from the peak point to the connecting line between both end portions of the fan blade 110 is the largest. Based on this kind of design for flabellum 110 is backward protruding, can improve flabellum 110's bulk strength on the one hand, and on the other hand can also improve flabellum 110's air pocket effect, can promote fan assembly 100's the amount of wind that blows to a certain extent.

In other embodiments, the fan blade 110 has a V-shaped structure, i.e., the two ends of the fan blade 110 are located forward and the middle is located backward, so that the fan blade 110 protrudes backward. In this way, the overall strength and blowing effect of the fan blade 110 can be improved as well.

Referring to fig. 5 and 8, in order to expand or retract the fan blades 110 relative to the driving mechanism 120, in the embodiment of the present application, a synchronization disc 130 is additionally disposed on the driving mechanism 120, the synchronization disc 130 is rotatably disposed on the driving mechanism 120, and a plurality of guide slots 131 are disposed on the synchronization disc 130, each fan blade 110 corresponds to one guide slot 131, and the guide slots 131 have a first end and a second end that are disposed opposite to each other. Accordingly, the fan blades 110 have the guiding structure 114, the guiding structure 114 is movably disposed in the guiding slot 131, the fan blades 110 are all in the unfolded state when the guiding structure 114 is located at the first end of the guiding slot 131, and the fan blades 110 are all in the folded state when the guiding structure 114 is located at the second end of the guiding slot 131. Alternatively, the guide structure 114 may be a guide post, guide pin, guide shaft, or the like, disposed at the trailing end 117 of the fan blade 110. In an initial state, the fan blades 110 are in a retracted state, at this time, the guide structure 114 is located at the second end of the guide slot 131, the fan blades 110 start to be unfolded along with the rotation of the fan blades 110 driven by the driving mechanism 120, at this time, the guide structure 114 moves from the second end to the first end along the guide slot 131, when the fan blades 110 are completely unfolded, the guide structure 114 moves to the first end of the guide slot 131, and in this process, the synchronization disc 130 rotates a certain angle adaptively along with the unfolding process of the fan blades 110, so as to prevent an obstruction effect on the unfolding process of the fan blades 110. The process of switching the fan blades 110 from the unfolded state to the folded state is opposite to the above process of switching the folded state to the unfolded state, that is, the guiding structure 114 moves from the first end to the second end.

Based on the above arrangement, the synchronous expansion or synchronous folding of the plurality of fan blades 110 can be realized through the synchronization disc 130, and the rotation angle of the fan blades 110 can be limited through the guide slot 131 on the synchronization disc 130, so that the fan blades 110 can respectively satisfy the requirements of the expansion and folding states.

Referring to fig. 8, the guide groove 131 includes a first groove portion 1311 and a second groove portion 1312 communicating with each other, and an extending direction of the first groove portion 1311 and an extending direction of the second groove portion 1312 are arranged at an angle. Alternatively, the first slot 1311 is a linear slot, the second slot 1312 is a linear slot, and one end of the first slot 1311 is connected to one end of the second slot 1312, so that the first slot 1311 and the second slot 1312 together form the V-shaped guide slot 131, and the V-shaped guide slot 131 guides the guide structure 114, so that the synchronous unfolding or synchronous folding of the blades 110 can be realized by the synchronization disk 130, and the motions of the blades 110 can be kept synchronous.
