Description

Technical Field

[0001] This application relates to an air outlet assembly and a bladeless fan, and is applicable to the technical field of fans. Background Technology

[0002] Existing bladeless fans typically employ a ring-shaped air outlet assembly, where air is transported along the entire ring. This results in a long airflow distance, leading to higher noise levels, lower airflow speeds, and a tendency for air to accumulate within the duct. For example, Chinese patent CN201902349U discloses a bladeless electric fan structure comprising: a base, a support, and an air outlet. The support is connected to the base and houses a motor and fan blades mounted on the motor's output shaft. The top edge of the support has a locking mechanism, and the air outlet is a circular frame with an air outlet on its inner edge. The air outlet and the support are engaged via the locking mechanism. In this patented solution, the ring-shaped airflow duct of the air outlet has a long airflow distance, and the ring-shaped air outlet design still suffers from high noise levels, low airflow speeds, uneven airflow, and a tendency for air to accumulate. Utility Model Content

[0003] The purpose of this application is to design an air outlet component and a bladeless fan, which aims to solve the problems of low air velocity, high noise, and uneven air distribution in existing air outlet components.

[0004] This application relates to an air outlet assembly, which includes an air outlet frame support column and an air outlet frame. The air outlet frame support column is provided with an air outlet frame support column air duct, and the air outlet frame is provided with an air outlet air duct. The air outlet frame support column is connected to the air outlet frame so that the air outlet frame support column air duct is connected to the air outlet air duct. An air outlet is provided on the air outlet frame.

[0005] The air outlet assembly may further include an air guide; the air guide may be disposed at the connection between the air outlet frame support column air duct and the air outlet air duct; an air duct interface is provided between the air outlet frame support column and the air outlet frame, and an air duct flare is formed inside the air duct interface; the air guide may be disposed within the air duct flare, so that the air duct flare forms an air guide air duct; the air guide air duct is connected to the air outlet air duct of the air outlet frame; air guide surfaces are formed on both sides of the air guide, and the air guide air duct is formed between the air guide surfaces and the inner wall of the air duct flare; the air outlet frame may have The system is equipped with multiple air outlets; each of the multiple air outlets is connected to the air outlet duct; each of the air outlets is provided with a guide rib within the air outlet duct at the position of the air outlet; the width of the air outlet duct gradually decreases from the connection point between the air outlet frame support duct and the air outlet duct to both sides; the air outlet assembly may further include an air outlet frame cover and a guide rib cover, the guide rib cover being disposed within the air outlet duct and forming a sealed duct with the air outlet duct, the air outlet frame cover being fitted to the outside of the guide rib cover, or the air outlet frame cover and the guide rib cover being integrally formed.

[0006] This application also provides a bladeless fan, including the air outlet assembly as described above.

[0007] The fan may include at least two air outlet components; the at least two air outlet components cooperate to form an annular air outlet surface of the fan; the fan may also include a base component or a column component, the air outlet components are disposed on the base component or the column component, and the air duct of the base component or the column component is connected to the air duct of the air outlet frame support column.

[0008] The air outlet assembly proposed in this application connects the air outlet frame support pillar to the air outlet frame and connects the air outlet frame support pillar duct to the air outlet duct. This allows the air outlet frame to independently deliver air through the air outlet frame support pillar, thereby increasing the air outlet velocity and reducing noise. The air outlet assembly proposed in this application uses at least two of the proposed air outlet assemblies to form an air outlet surface, which shortens the air delivery distance of a single air outlet assembly, thereby increasing the air velocity, reducing noise, and avoiding the problem of air congestion caused by excessively long ducts. The air outlet assembly proposed in this application, through the rational design of air guides within the air outlet frame support pillar and the air outlet frame duct, makes the air outlet from the air outlet frame more uniform and reduces noise.

[0009] The bladeless fan proposed in this application, by employing the aforementioned air outlet components, effectively improves airflow efficiency and energy efficiency, thereby enhancing the user experience. The design, which involves multiple air outlet components joined together to form a ring-shaped air outlet structure, is novel and aesthetically pleasing. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be arbitrarily combined with each other.

[0022] like Figure 1-4As shown, this application proposes an air outlet assembly 3, which includes an air outlet frame support column 31 and an air outlet frame 32. Preferably, the air outlet frame 32 can be a one-piece molded structure, which facilitates the formation of an air outlet duct and independent air outlet. The air outlet frame support column 31 has an air outlet frame support duct, and the air outlet frame 32 has an air outlet duct 323; specifically, the air outlet frame support column 31 is connected to the air outlet frame 32 so that the air outlet frame support duct and the air outlet duct 323 are connected, and the two can be integrally molded or separately molded. Figure 3 As shown, the air outlet frame 32 is provided with an air outlet 321, and the air outlet 321 is connected to the air outlet duct 323 to realize air blowing. Preferably, the cross-sections of the air outlet frame 32 and the air outlet duct 323 are both gradually narrowing sections, and the air outlet 321 is located at the narrowest point of the air outlet duct 323. This design is beneficial to increasing the air outlet velocity. The air outlet assembly proposed in this application, by designing the air outlet frame support column to connect with the air outlet frame and realize the air duct connection, can independently deliver air to the air outlet frame through the air outlet frame support column, thereby increasing the air outlet velocity and reducing noise.

[0023] like Figure 1-4 As shown, in some embodiments, the air outlet assembly 3 further includes an air guide 35. The air guide 35 is disposed at the connection between the air outlet frame support duct and the air outlet duct 323 to guide airflow to both sides of the air outlet duct 323. By adopting the above solution, by providing an air guide 35 at the connection between the air outlet frame support duct and the air outlet duct 323, the airflow in the air outlet frame support duct can be guided by the air guide 35, thereby quickly and evenly entering both sides of the air outlet duct 323, improving air outlet efficiency, and making the airflow from the air outlet duct more balanced.

[0024] like Figure 1-5 As shown, in some embodiments, one end of the air outlet frame support 31 has an air duct interface 311, and an air duct flare is formed within the air duct interface 311. The air duct interface 311 is connected to the air outlet frame 32, specifically to the middle position of the air outlet frame 32, and the connection method can be split molding or integral molding. The air guide 35 is disposed within the air duct flare, so that the air duct flare forms an air guide duct; the air guide duct is connected to the air outlet duct 323 to realize air guidance. With the above scheme, the air duct flare can expand the air outlet space, facilitate the installation and diversion of the air guide 35, and can also expand the connection surface between the air duct interface 311 and the air outlet frame 32, making the structure more stable.

[0025] like Figure 3-5As shown, in some embodiments, the cross-section of the air guide 35 has a herringbone structure. Arc-shaped air guide surfaces are formed on both sides of the air guide 35, and an air guide channel is formed between these arc-shaped air guide surfaces and the inner wall of the duct flare. This air guide channel is connected to the outlet air duct 323. Preferably, the duct flare is connected to the outlet air duct 323, specifically to the middle position of the outlet air duct 323, for connecting the air duct. Specifically, the air guide channel includes a first air guide channel 314 and a second air guide channel 315; the first air guide channel 314 is connected to one side of the outlet air duct 323, and the second air guide channel 315 is connected to the other side of the outlet air duct 323, thereby guiding air along both sides of the outlet air duct 323, resulting in more even airflow.

[0026] like Figure 7-9 As shown, in some embodiments, the air outlet frame 32 is provided with multiple air outlets 321, and the air outlets 321 can be elongated structures. Preferably, the multiple air outlets 321 are evenly distributed along the length direction of the air outlet frame 32, for example... Figure 7 On the circumference of the air outlet frame 32, and on the end face of the air outlet frame 32, multiple air outlets 321 are connected to the air outlet duct 323. Specifically, a guide rib 322 is provided at the position of each air outlet 321 in the air outlet duct 323. This design allows the air outlet volume to be adjusted according to the distance between the air outlet and the duct interface by setting the guide ribs to different lengths or shapes, so that the air in the air outlet duct 323 is evenly discharged through the air outlet 321, thus solving the problem of air congestion in the air outlet duct.

[0027] like Figure 6-8 As shown, in some embodiments, the air outlet frame 32 has an arc-shaped structure, preferably a semi-circular arc structure. The air outlet frame 32 is designed as an arc-shaped structure, and the air outlet duct 323 is also an arc-shaped duct. The width of the arc-shaped duct gradually decreases from the connection point between the air outlet frame support duct and the air outlet duct 323 towards both sides. This design allows the airflow from the air outlet duct 323 to be blown out stably and evenly from each air outlet 321, taking advantage of the gradually decreasing airflow through each air outlet. The air outlet assembly proposed in this application, by setting the air outlet frame to an arc-shaped structure, shortens the air outlet duct, allowing the air entering the duct to be quickly expelled, increasing the airflow velocity, reducing noise, and avoiding the problem of airflow accumulation caused by an excessively long air outlet duct.

[0028] like Figure 2-4 As shown, in some embodiments, the air outlet assembly 3 further includes an air outlet frame cover 33 and an air guide cover 34; wherein, the air guide cover 34 is disposed within the air outlet duct 323 and forms a sealed air duct with the air outlet duct 323, improving air guiding efficiency and air outlet efficiency. The air outlet frame cover 33 and the air guide cover 34 can be integrally formed or assembled separately. In embodiments where they are assembled separately, such as... Figure 4As shown, the air outlet frame cover 33 is located on the outside of the air guide cover 34 and covers the air guide cover 34, serving the functions of overall sealing, protection, and decoration.

[0029] like Figure 1 As shown, this application also provides a fan, which is a bladeless fan. Specifically, the bladeless fan includes an air outlet assembly 3, which is the air outlet assembly described above. Multiple air outlet assemblies 3 can be designed, preferably two, with each of the two air outlet assemblies 3 connected to a connecting base 22 to form an annular air outlet assembly. This effectively improves airflow efficiency and enhances the user experience. Compared to a single-strip air outlet assembly, the annular air outlet assembly creates a more uniform and gentler airflow effect.

[0030] like Figure 1 , 10 As shown, in some embodiments, the fan proposed in this application further includes a base assembly 1 and a column assembly 2, wherein the column assembly 2 is disposed on the base assembly 1; the air outlet assembly 3 is disposed on the column assembly 2, and the column air duct of the column assembly 2 is connected to the air outlet support column air duct of the air outlet frame support column 31. Further, a fan 11 is provided inside the base assembly 1, which absorbs air from the external environment by rotation and forms an airflow through the column air duct 21, the airflow direction being referenced... Figure 10 The F direction is shown.

[0031] like Figure 1 and 10 As shown, in some embodiments, the column assembly 2 is provided with a connecting seat 22, and the fan includes at least two air outlet assemblies 3; the at least two air outlet assemblies 3 are respectively connected to the connecting seat 22 to cooperate in forming the air outlet surface of the fan. Preferably, the at least two air outlet assemblies 3 cooperate to form an annular air outlet surface to achieve circumferential air outlet. Specifically, the air outlet frame support column 31 is connected to the connecting seat 22 on the column assembly 2, and the air outlet frame support column air duct is connected to the transmission air duct of the connecting seat 22.

[0032] like Figure 1 and 10 As shown, in some embodiments, the connecting seat 22 is provided with a main air duct; the other end of the air outlet frame support 31 is connected to the connecting seat 22, so that the air outlet frame support duct is connected to the main air duct in the connecting seat 22. Preferably, as Figure 2 and 4As shown, the other end of the air outlet frame support 31 is connected to the connecting seat 22 via a snap-fit ​​structure. Specifically, the snap-fit ​​structure includes a latch 312 and a limiting boss 313 respectively disposed on the air outlet frame support 31, and a latch and a limiting groove respectively disposed on the connecting seat 22. The latch 312 and the latch are mutually adapted and can be fastened together; the limiting boss 313 and the limiting groove are mutually adapted and can be snapped together. The latch 312 and the limiting boss 313 are not limited to being disposed on the air outlet frame support 31, but can also be disposed on the connecting seat 22; similarly, the latch and the limiting groove can also be disposed on the air outlet frame support 31. Furthermore, the latch 312 and the limiting boss 313 do not necessarily need to be disposed on the same component; they can be disposed separately. Similarly, the latch and the limiting groove can also be disposed separately, as long as the latch 312 and the latch can be mutually fastened together, and the limiting boss 313 and the limiting groove can be mutually snapped together.
