Example 1

The present utility model provides an air supply assembly 100 for promoting air flow. In one illustrative scenario, the air moving assembly is a bladeless fan. The following description will be mainly made on the scenario in which the air supply assembly is used as a bladeless fan. It will be appreciated from the foregoing that the scope of embodiments of the utility model is not limited thereby.

Referring to fig. 1 to 4, the air supply assembly includes: housing 110 and power source 120 disposed within housing 110. The housing 110 has a hollow interior, and the power source 120 has a structure capable of forming negative pressure in the housing 110.

The housing 110 has an inner flow passage (not shown) through which an air flow is induced, and external air enters the housing 110 by the power source 120 and flows out of the housing 110 through the inner flow passage, thereby promoting the air flow.

In the present embodiment, as shown in fig. 1 to 3, the housing 110 includes an air collecting housing portion 111 and a power mounting housing portion 112, wherein the air collecting housing portion 111 and the power mounting housing portion 112 are hollow-interior housings, and the air collecting housing portion 111 and the power mounting housing portion 112 are in communication.

Further, an air outlet channel 130 is provided in the air collecting shell portion 111, and an opening 113 communicating with the air outlet channel 130 is also provided on the shell wall of the air collecting shell portion 111. The opening 113 is an air outlet of the internal flow channel, and is used for air outlet.

Further, the power source 120 is disposed in the hollow cavity of the power installation shell 112, and the hollow cavity of the power installation shell 112 is communicated with the air outlet channel 130. The shell wall of the power installation shell 112 is also provided with an inlet 114 for air inlet, and the inlet 114 is communicated with the opening 113 through a hollow cavity of the power installation shell 112 and an air outlet channel 130.

In the present embodiment, the inlet 114, the hollow cavity of the power installation housing 112, the air outlet passage 130, and the opening 113 form an internal flow path of the housing case 110.

When the power source 120 operates, a negative pressure suction force is formed inside the housing 110, and external air enters the power installation housing 112 through the inlet 114 by the negative pressure suction force and is discharged out of the housing 110 through the air outlet passage 130 and the opening 113. That is, the power source 120 is used to allow outside air to enter the air outlet passage 130 and be discharged through the opening 113.

Referring to fig. 3 and fig. 4, in order to make the opening 113 have better air outlet performance, a first air-distributing member 150 and a second air-distributing member 160 are disposed in the opening 113. The first wind homogenizing member 150 and the second wind homogenizing member 160 all have the following functions: the diversion capacity is improved, so that the airflow is uniformly discharged from the opening 113, and the occurrence of the wind blocking phenomenon is reduced.

Referring to fig. 5 and 6, the first wind homogenizing member 150 has a first distal end M far from the opening 113 side, and the second wind homogenizing member 160 has a second distal end N far from the opening 113 side. Wherein the first distal end M is disposed closer to the opening 113 than the second distal end N; alternatively, the second distal end N is disposed closer to the opening 113 than the first distal end M. That is, the first distal end M and the second distal end N are different in height, i.e., the first distal end M and the second distal end N are not located at the same height and are staggered in the height direction. The height direction refers to the up-down direction in the drawing.

In this embodiment, in the process of flowing the air flow in the air outlet channel 130, since the first distal end M of the first air-homogenizing member 150 and the second distal end N of the second air-homogenizing member 160 are located at different heights, the first air-homogenizing member 150 and the second air-homogenizing member 160 can achieve the purposes of guiding and splitting the air step by step, so that the occurrence frequency of the air blockage phenomenon can be effectively reduced, and the uniformity of the air outlet can be improved.

Referring to fig. 2 and 4, the adjacent first wind-equalizing members 150 are disposed at intervals, and the second wind-equalizing member 160 is disposed in the above-mentioned interval region between the adjacent first wind-equalizing members 150. Of course, the adjacent second wind-homogenizing members 160 may be disposed at intervals, and the first wind-homogenizing member 150 may be disposed in the above-described interval region between the adjacent second wind-homogenizing members 160.

Specifically, if the first distal end M is disposed farther from the opening 113 than the second distal end N, the first distal end M first acts on the airflow in the air outlet channel 130, and the airflow in the air outlet channel 130 is forced to split by the first air homogenizing member 150. Meanwhile, the air flow split by the first air-distributing member 150 is forced to split again under the action of the second air-distributing member 160, so that the uniformity of the air outlet of the opening 113 is effectively improved.

For convenience of explanation, the number of the first wind homogenizing members 150 is now defined as four, the openings 113 are defined as circular rings, and referring to fig. 7, the four first wind homogenizing members 150 divide the openings 113 into four wind outlet areas, which are respectively a wind outlet area a, a wind outlet area B, a wind outlet area C and a wind outlet area D. At least one second air homogenizing member 160 is arranged in each air outlet area, the number of the second air homogenizing members 160 is now defined as two, and the two second air homogenizing members 160 in the air outlet area A further divide the air outlet area A into an A1 area, an A2 area and an A3 area. Similarly, the second air-homogenizing member 160 in the air outlet area B further divides the air outlet area B into an area B1, an area B2 and an area B3; the second air homogenizing piece 160 in the air outlet area C further divides the air outlet area C into a C1 area, a C2 area and a C3 area; the second wind homogenizing member 160 in the wind outlet area D further divides the wind outlet area D into a D1 area, a D2 area and a D3 area.

As can be seen from the above description, the air flow in the air outlet channel 130 can be split into the air outlet area a, the air outlet area B, the air outlet area C and the air outlet area D under the action of the first air-homogenizing member 150, and the air flow can be further split under the action of the second air-homogenizing member 160 in the process of passing through the air outlet area, so that the purposes of guiding and splitting step by step are achieved, and the air outlet uniformity is effectively improved.

In this embodiment, as shown in fig. 2, preferably, the first wind homogenizing members 150 and the second wind homogenizing members 160 are alternately arranged, and the first wind homogenizing members 150 and the second wind homogenizing members 160 are arranged at equal intervals, which has the advantages of good diversion and wind homogenizing effects and elegant appearance.

In this embodiment, as shown in fig. 5, the first air balancing piece 150 includes a first air guiding portion 151 located in the air outlet channel 130, and a first separating portion 152 connected to the first air guiding portion 151, where the first separating portion 152 is closer to the opening 113 than the first air guiding portion 151.

Similarly, as shown in fig. 6, the second wind-equalizing member 160 includes a second wind guiding portion 161 located in the wind outlet channel 130, and a second separating portion 162 connected to the second wind guiding portion 161, where the second separating portion 162 is closer to the opening 113 side than the second wind guiding portion 161.

In the present embodiment, each of the first and second

wind guide portions

151 and 161 is an arc plate curved in the upwind direction. The first distal end M is an end of the first air guiding portion 151 on the side away from the first partition portion 152; the second distal end N is an end of the second air guiding portion 161 on the side away from the second partition portion 162. The first air guide 151 and the second air guide 161 are arc-shaped: the device is used for adapting to the incoming flow angle and incoming flow speed of the airflow, avoiding impact loss and improving the flow guiding capability and flow guiding effect. The upwind direction is the direction opposite to the flow direction of the air flow in the air outlet channel 130.

The first and

second partitions

152 and 162 are parallel, and the first and

second partitions

152 and 162 partition the opening 113 into a plurality of spouts. Wherein the first and

second partitions

152 and 162 extend in a direction (up-down direction) perpendicular to the horizontal plane, respectively, so that the air flow ejected from the nozzle flows out in the direction perpendicular to the horizontal plane. Therefore, the pain point of the air outlet inclination is effectively solved.

Further, the top end surface of the air outlet channel 130 is inclined with respect to the horizontal plane, the side of the top end surface of the air outlet channel 130 close to the power source 120 is a high-level end, and the side of the top end surface of the air outlet channel 130 far from the power source 120 is a low-level end. Therefore, when the air flows in the air outlet channel 130, the air flow is forced to change the flow direction under the influence of the transverse stress of the top end surface of the air outlet channel 130, and flows out from the nozzle along the direction perpendicular to the horizontal plane, so that the problem of air outlet inclination is further avoided.

In the present embodiment, as shown in fig. 2 and 3, the number of the power sources 120 is 2, and the power installation housing portions 112 are disposed in one-to-one correspondence with the power sources 120. The power mounting housing portions 112 are independent of each other, which means: the power mounting housing portions 112 are not in communication with each other.

Two independent air outlet passages 130 are respectively formed in the air collecting casing 111, and each air outlet passage 130 corresponds to one power source 120. That is, each of the air outlet passages 130 is provided with a power source 120 for providing driving force thereto.

The housing 110 has an axisymmetric structure, the air collecting housing 111 has a ring shape, and the power mounting housing 112 is symmetrically disposed on the air collecting housing 111. The two air outlet passages 130 in the air collecting housing 111 are enclosed together to form an annular region, and the openings 113 are located on the wall of the air collecting housing 111 corresponding to the annular region.

Example two

Referring to fig. 8, the present utility model further provides a lighting device, which includes a housing 200 and the air supply assembly 100 according to the first embodiment, wherein the air supply assembly 100 is disposed on the housing 200.

It will be apparent that the embodiments described above are merely some, but not all, embodiments of the utility model. Based on the embodiments of the present utility model, those skilled in the art may make other different changes or modifications without making any creative effort, which shall fall within the protection scope of the present utility model.
