Description

Technical Field

[0001] The utility model belongs to the technical field of fan lamps, and in particular relates to an air outlet adjustment mechanism and a bladeless fan lamp. Background Art

[0002] A fan light is a household appliance that combines a lamp with a fan. It has both lighting and blowing functions. According to the presentation form of the fan blades, fan lights are divided into leafed fan lights and leafless fan lights. Leafless fan lights can adjust the wind speed and air volume by adjusting the motor speed and the size of the air outlet.

[0003] At present, the common bladeless fan lights on the market mostly have fixed air ducts, and due to the size limitations of bladeless fan lights, it is not possible to take into account both the air outlet range and wind speed when blowing air. For example, when the blowing range is large, the corresponding wind speed is low; when the wind speed is high, the air outlet range is small. In addition, in these bladeless fan lights, since the impeller (wind wheel) is installed in an air outlet chamber with an air outlet, when it is necessary to clean the dust on the impeller, most of the products need to be disassembled, such as the air guide cover and the housing, which will cause trouble for users with poor hands-on ability.

[0004] The prior art discloses an adjustable fan light, including a fan light body, a fan blade movably mounted at the bottom of the fan light body, an adjustable air outlet assembly screwed and fixed on the fan light body, an air inlet is provided on the upper surface of the guard frame of the adjustable air outlet assembly, and an air outlet is provided at the bottom of the guard frame, and a first adjustment piece, a second adjustment piece, a third adjustment piece and a fourth adjustment piece are movably mounted inside the air outlet. In the adjustable fan light, the wind direction of the fan's air outlet is adjusted by adjusting the angles of the four groups of adjustment pieces. However, the four groups of adjustment pieces of the adjustable fan light are all located at the bottom of the air outlet and are driven by the same motor, that is, the air can only be discharged in one direction, and the air outlet range cannot be expanded.

[0058] Example 1

[0059] refer to Figure 1-Figure 6 The present embodiment provides an air outlet adjustment mechanism 100 for adjusting the air outlet of a bladeless fan lamp or a bladeless fan. The air outlet adjustment mechanism 100 includes a base 1, a shell 2 and a drive assembly 3. A base 11 is provided on the base 1, and a wind wheel 4 is installed on the base. The wind wheel 4 is a centrifugal impeller, which blows air outward and downward when rotating. The shell 2 is arranged around the outside of the base 1, and a first air outlet 101 is arranged between the shell 2 and the base 1. The shell 2 of the present embodiment is an inverted bowl-shaped structure, that is, the shell 2 is raised upward as a whole and has a circular opening 201, and the base 1 is located in the circular opening 201. It can be understood that the first air outlet 101 is a gap formed by the outer peripheral edge of the base 1 and the side wall of the shell 2, and the first air outlet 101 is also located in the circular opening 201.

[0060] The housing 2 includes a housing body 21 and an air guide 22 , wherein the housing body 21 is provided with a second air outlet 102 , and the air guide 22 is mounted on the second air outlet 102 .

[0061] The driving assembly 3 is mounted on the housing body 21, and the air guide 22 is movably connected to the housing body 21 through the driving assembly 3. Driven by the driving assembly 3, the air guide 22 rotates up and down relative to the housing body 21, thereby adjusting the opening range of the second air outlet 102.

[0062] In the present embodiment, an air inlet 211 is provided at one end of the shell body 21, and a first air outlet 212 is provided at the other end. The first air outlet 212 is formed by the shell body 21 extending in an arc shape in a direction away from the air inlet 211. The air guide 22 is provided with a second air outlet 221. As mentioned above, the air guide 22 and the shell body 21 together constitute the shell 2 of the present embodiment. When the air guide 22 completely covers the second air outlet 102, the first air outlet 212 and the second air outlet 221 together surround and form a ring-shaped air outlet bottom end 210. The circular opening 201 is located on the inner side of the air outlet bottom end 210, and the opening size of the circular opening 201 is larger than the opening size of the air inlet 211.

[0063] In some embodiments, the second air outlet end 221 is flush with the first air outlet end 212 , and the air outlet bottom end 210 is an annular structure, and the air outlet bottom end 210 and the circular opening 210 are located on the air outlet end surface 202 of the housing 2 .

[0064] In some other embodiments, the second air outlet end 221 is not flush with the first air outlet end 212 , that is, the second air outlet end 221 protrudes downward from the air outlet end surface 202 .

[0065] The air outlet adjustment mechanism 100 of this embodiment adopts an air outlet bottom end structure in which the second air outlet end 221 and the first air outlet end 212 are flush with each other. At this time, the second air outlet end 221 and the first air outlet end 212 are located together on the air outlet end surface 202 of the shell 2; the circular opening 201 is also located on the air outlet end surface 202.

[0066] It should be noted that when the second air outlet 102 is completely covered by the air guide 22, the first air outlet 101 and the second air outlet 102 form an annular air outlet 103. At this time, the wind generated by the wind wheel 4 flows out to the outside through the annular air outlet 103.

[0067] When the air guide 22 is opened and away from the shell body 21, the second air outlet 102 is opened and connected with the first air outlet 101; as the opening angle of the air guide 22 increases, the opening amplitude of the second air outlet 102 increases. When the air guide 22 is not fully opened (for example, the opening angle of the air guide 22 is less than 90°), part of the airflow generated by the wind wheel 4 flows downward to the outside through the first air outlet 101, and then forms turbulence; the other part flows obliquely downward to the outside through the second air outlet 102 under the guidance of the air guide 22.

[0068] Among the wind (airflow) flowing out to the outside through the second air outlet 102, part of it will also escape along the circumference of the shell body. In order to reduce or avoid horizontal airflow escape, the shell body 21 of this embodiment is provided with a first wind shield 213, which is arranged on both sides of the second air outlet 102, and the first wind shield 213 is formed by extending outward from the shell body 21; correspondingly, the wind guide 22 is also provided with a second wind shield 222 on both sides, the second wind shield 222 matches the shape of the first wind shield 213, and the second wind shield 222 is closely connected to the first wind shield 213. In this way, in the process of the wind guide 22 opening upward, the second wind shield 222 cooperates with the first wind shield 213 to reduce or avoid the wind generated by the wind wheel from escaping along the circumference of the shell body; at the same time, the wind generated by the wind wheel is controlled to flow out to the outside only along the first air outlet 101 and the second air outlet 102.

[0069] In this embodiment, the second air outlets 102 are evenly arranged in the housing body 21, and there are three second air outlets 102; correspondingly, the first wind shields 213 and the second wind shields 222 are respectively arranged in three pairs. In other embodiments, the number of the second air outlets 102, the first wind shields 213 and the second wind shields 222 can also be adjusted according to the air outlet conditions.

[0070] The housing body 21 is provided with a first mounting seat 214, which is located at the upper edge of the second air outlet 102 and is used to mount the rotating shaft of the air guide member 22. Figure 4The projection of the first wind shield 213 on the air outlet end surface 202 is perpendicular to the projection of the first mounting seat 214 on the air outlet end surface 202. In this way, when the air guide 22 rotates up and down with the central axis parallel to the first mounting seat 214 as the rotation axis, the first wind shield 213 always blocks the airflow from flowing out to the outside along the circumference of the shell body.

[0071] The wind guide 22 is provided with a second mounting seat 223, which is located at one end of the wind guide 22, such as the upper end; the second air outlet end 221 is located at the other end of the wind guide 22, such as the lower end. The wind guide 22 is provided with an arc-shaped wind guide surface 220 between the second mounting seat 223 and the second air outlet end 221. When the airflow generated by the wind wheel passes through the second air outlet 102, it will be guided by the wind guide surface 220 and blocked by the second wind shield 222, so that all the air will eventually flow obliquely downward to the outside through the second air outlet end 221.

[0072] The driving assembly 3 is used to drive the air guide member 22 to rotate relative to the housing body 21. The driving assembly 3 includes a first driving member 31, a second driving member 32 and a stepping motor 33; wherein the stepping motor 33 is drivingly connected to the second driving member 32, the first driving member 31 is fixedly connected to the housing body 21, and the second driving member 32 is fixedly connected to the air guide member 22. Under the drive of the stepping motor 33, the second driving member 32 is rotationally connected to the first driving member 31.

[0073] Specifically, the first driving member 31 includes a first connecting block 311 and a first sleeve 312, the first sleeve 312 is fixedly connected to the first connecting block 311, and the first sleeve 312 has a first through hole 313. The second driving member 32 includes a second connecting block 321, a second sleeve 322 and a rotating shaft 323, the second sleeve 322 is fixedly connected to the second connecting block 321; one end of the rotating shaft 323 penetrates into the second sleeve 322 and is fixedly connected to the second sleeve 322, and the other end of the rotating shaft 323 penetrates into the first sleeve 312 through the first through hole 313 and is rotatably connected to the first sleeve 312.

[0074] When the driving assembly 3 is mounted to the housing 2, the first connecting block 311 of the first driving member 31 is fixedly connected to the housing body 21, the first sleeve 312 and the second sleeve 322 are mounted on the first mounting seat 214; the second connecting block 321 is fixedly connected to the second mounting seat 223. At this time, driven by the stepping motor 33, the air guide member 22 can rotate relative to the housing body 21 with the rotating shaft 323 as the rotating shaft.

[0075] It should be noted that the first connecting block 311 and the second connecting block 321 of the present embodiment are hinge-like structures, and screw holes 34 are provided on the first connecting block 311 and the second connecting block 321. Screws (not marked) pass through the screw holes 34 to fix the first connecting block 311 to the shell body 21, and to fix the second connecting block 321 to the air guide member 22.

[0076] In order to cooperate with the first sleeve 312 and the second sleeve 322, the air guide member 22 is provided with an arc-shaped rotation groove 224 on the side of the second mounting seat 223 close to the shell body 21, so as to accommodate the first sleeve 312 and the second sleeve 322, so that the air guide member 22 can rotate smoothly with the rotating shaft 323 as the rotating axis.

[0077] Continue to refer Figure 2 A wind guide seat 12 is provided on the base 1, and the wind guide seat 12 is located on the outside of the base 11, and the wind guide seat 12 and the shell 2 are surrounded to form an air duct 10. The wind generated by the wind wheel 4 passes through the air duct 10 and then enters the first air outlet 101 to blow to the outside; or enters the first air outlet 101 and the second air outlet 102 respectively to blow to the outside.

[0078] The air guide seat 12 is provided with a third air outlet end 121 at the edge, wherein the third air outlet end 121 is lower than or flush with the air outlet end surface 202 of the housing 2. In this embodiment, the third air outlet end 121 is lower than the air outlet end surface 202, that is, the third air outlet end 121 protrudes downward from the air outlet end surface 202, so that the third air outlet end 121 can guide the wind (airflow) generated by the wind wheel to flow downward together with the first air outlet end 212 and the second air outlet end 221, thereby ensuring the air outlet volume at the bottom of the base 1.

[0079] The air outlet adjustment mechanism provided in the present embodiment is provided with a first air outlet between the shell and the base, and the shell is also provided with a second air outlet on the shell body; the driving component drives the air guide member to rotate relative to the shell body, and adjusts the opening amplitude of the second air outlet, thereby changing the size of the first air outlet and the second air outlet, and finally adjusting the blowing range and the air outlet speed, which can increase the blowing range while taking into account the central air outlet.

[0080] Example 2

[0081] exist Figure 1-Figure 6 Based on the reference Figure 7-Figure 9 This embodiment provides a bladeless fan lamp, including a wind wheel 4, a lighting module (not shown in the figure) and an air outlet adjustment mechanism 100 of embodiment 1. The air outlet adjustment mechanism 100 is provided with a light outlet cavity 13 inside a base 1. The lighting module is installed in the light outlet cavity 5 and projects light downward to achieve lighting. The wind wheel 4 is installed on a base 11 of the base 1 and rotates under the drive of a motor to achieve blowing.

[0082] The housing 2 has an air outlet end surface 202 , and the light outlet end surface 202 has a normal line L. The air guide 22 is provided with a convex edge 225 above the second air outlet end 221 , wherein a section of the side where the convex edge 225 intersects with the second wind shielding plate 222 is a line segment MN.

[0083] When the air guide 22 completely covers the second air outlet 102, that is, when the second air outlet 102 is completely closed, the second air outlet end 221 is flush with the air outlet end surface 202. The projections of point M and point N on the air outlet end surface 202 are the same, both of which are point A. As the air guide 22 opens upward, the angle between the line segment MN and the normal line L of the air outlet end surface is the opening angle of the air guide 22.

[0084] like Figure 7 As shown, at this time, the line segment MN coincides with the normal line L passing through point M or point N, the opening angle of the air guide 22 is 0°, the second air outlet 102 is completely covered by the air guide 22, and the first air outlet 101 and the second air outlet form a ring-shaped air outlet 103. Figure 8 As shown, when the second air outlet 102 is closed, the airflow generated by the wind wheel flows out to the outside through the annular air outlet 103 and blows downward.

[0085] like Fig. 9 As shown, the air guide 22 rotates upward relative to the housing body 21 with the rotating shaft 323 as the rotating axis under the driving action of the driving assembly 3. At this time, the angle between the line segment MN and the normal line L is 45°, that is, the opening angle of the air guide 22 is 45°. Fig.10 As shown, part of the airflow generated by the wind wheel 4 is blown downward from the first air outlet 101; the other part of the airflow is blown obliquely downward from the second air outlet 102 at an angle of 45° under the guidance of the air guide 22. When this part of the airflow is blown obliquely downward through the second air outlet 102, the first wind shield 213 and the second wind shield 222 cooperate with each other to prevent the airflow from escaping horizontally along the circumference of the shell body 21, that is, this part of the airflow is controlled to be guided by the second air outlet 102 to flow out to the outside, thereby realizing the blowing function.

[0086] like Fig.11 As shown, the air guide member 22 continues to rotate upward under the drive of the stepper motor 3 of the driving assembly until it is fully opened. At this time, the angle between the line segment MN and the normal line L is 180°. It can also be said that the line segment MN is perpendicular to the air outlet end surface 202 again and is parallel to the normal line L.

[0087] The opening angle of the air guide 22 is 180°, and the second air outlet 221 also rotates 180° with the rotating shaft as the rotating axis. A part of the airflow generated by the wind wheel 4 blows downward from the first air outlet 101, and the other part of the airflow flows out to the outside along the second air outlet 102. At this time, the first wind shield 213 prevents the airflow from escaping horizontally along the circumference of the shell body 21.

[0088] When the wind wheel is not turned on, the user can directly clean and maintain the hidden wind wheel 4 and other components, such as cleaning the wind wheel with a towel or other cleaning tools.

[0089] The bladeless fan lamp provided in this embodiment adopts an air outlet adjustment mechanism with adjustable air outlet. While ensuring a higher wind speed at the center below the fan lamp, the blowing range can be increased according to user needs to meet the application needs of lighting and blowing in different places.

[0090] Example 3

[0091] exist Figure 7 , Fig. 9 and Fig.11 Based on this, further reference Figure 8 and Fig.10 . Figure 8 This is a schematic diagram of the air flow of a bladeless fan lamp when the air guide is opened at an angle of 45°. Fig.10 The figure is a schematic diagram of the air outlet of the bladeless fan lamp when the air guide is opened at an angle of 45°. Compared with when the air guide is not opened, the air outlet adjustment mechanism or the bladeless fan lamp with the air guide 22 opened at an angle of 45° can increase the air blowing radius by about one time, and at the same time ensure that the center below the fan lamp has a larger wind speed.

[0092] The above contents are merely examples and illustrations of the structure of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these obvious replacement forms all belong to the protection scope of the utility model.
