[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This embodiment provides an air outlet mechanism that can be used to outlet air, thereby achieving functions such as ordinary blowing, ventilation, and equalizing indoor temperature.

[0029] Please see Figures 1-7 The air outlet mechanism in this embodiment includes a main unit-air inlet assembly 1 and an air guide-air outlet assembly 2.

[0030] The main unit-air intake assembly 1 includes a main unit housing 11 and a fan device 12 housed within the main unit housing 11. The main unit housing 11 is a cylindrical engineering plastic shell, and the fan device 12 is a turbine-type fan driven by an electric motor (preferably a brushless DC motor), capable of driving airflow to generate airflow. At least a portion of the main unit housing 11 is provided with an air intake grille unit 111, and an initial air guiding space 10 is formed within the main unit housing 11. Specifically, the air intake grille unit 11... 1 is a cylindrical engineering plastic shell with several meshes / grids. Several meshes / grids can be integrally formed on the main unit shell 11 to form an air inlet grid unit 111, or several meshes / grids can be integrally formed on another cylindrical engineering plastic shell and the shell is coaxially fixedly connected (e.g., fastened) to the main unit shell 11 to form an air inlet grid unit 111; the initial air guiding space 10 is the space in the main unit shell 11, which extends along the axial direction of the main unit shell 11.

[0031] The air guide-exhaust assembly 2 includes an exhaust connecting arm unit 21 and an exhaust shell unit 22 connected to one end of the exhaust connecting arm unit 21. Both the exhaust connecting arm unit 21 and the exhaust shell unit 22 are made of engineering plastic. They can be integrally molded, or separate exhaust connecting arm unit 21 and exhaust shell unit 22 can be provided and fixedly connected (e.g., fastened together) to form the air guide-exhaust assembly 2. An intermediate air guide space 20 is formed within the exhaust connecting arm unit 21, and this intermediate air guide space 20 is the space within the exhaust connecting arm unit 21, extending along the extension direction of the exhaust connecting arm unit 21. Furthermore, an end air guide space 30 is formed within the air outlet shell unit 22. This end air guide space 30 is a space within the air outlet shell unit 22 and extends along the extension direction of the air outlet shell unit 22. Additionally, an air outlet 221 is provided at the air outlet shell unit 22 and communicates with the end air guide space 30. This air outlet 221 is actually an integrally formed through-groove or through-hole structure at the air outlet shell unit 22, which directly connects to the end air guide space 30 within the air outlet shell unit 22. The intermediate air guide space 20 is connected to the end air guide space 30, allowing the airflow in the intermediate air guide space 20 to flow to the end air guide space 30.

[0032] The air outlet connecting arm unit 21 of the air guide-air outlet assembly 2 is connected to the main unit housing 11 of the main unit-air inlet assembly 1, so that the initial air guide space 10 is connected to the intermediate air guide space 20, and the airflow in the initial air guide space 10 can flow to the intermediate air guide space 20.

[0033] The fan device 12 can drive the airflow from the air inlet grille unit 111 into the main unit housing 11 of the main unit-air inlet assembly 1, and run along the path of the initial air guide space 10, the intermediate air guide space 20 and the terminal air guide space 30 until it is ejected from the air outlet 221 of the air outlet housing unit 22.

[0034] Furthermore, the air outlet connecting arm unit 21 of the air guide-air outlet assembly 2 is pivotally connected to the main unit housing 11 of the main unit-air inlet assembly 1, and the air outlet connecting arm unit 21 can swing in the pitch direction around its pivot axis; specifically, the main unit housing 11 of the main unit-air inlet assembly 1 has an air outlet connecting hole 113 on its side, which is actually a through hole penetrating the side wall of the main unit housing 11. The end of the air outlet connecting arm unit 21 of the air guide-air outlet assembly 2 has a pivot axis (not shown in the figure), which is a hollow shaft with open ends. The pivot axis of the air outlet connecting arm unit 21 passes through the air outlet of the main unit housing 11. The air outlet connecting arm unit 21 is pivotally connected to the main unit housing 11 through the connecting hole 113. At this time, the internal space of the pivot shaft of the air outlet connecting arm unit 21 is connected to the initial air guide space 10 of the main unit housing 11 and the intermediate air guide space 20 of the air outlet connecting arm unit 21. By setting a rack on the pivot shaft and setting a motor with gears (not shown in the figure) in the main unit housing 11, the air outlet connecting arm unit 21 can be driven to swing around its pivot shaft in the pitch direction. In this way, the entire air guide-air outlet assembly 2 can swing in the pitch direction, thereby changing the air outlet angle in the pitch direction.

[0035] Furthermore, the air outlet connecting arm unit 21 of the air guide-air outlet assembly 2 is provided with several units, and each air outlet connecting arm unit 21 is arranged at a different position on the main unit-air inlet assembly 1; please refer to Figure 1 or Figure 6 In this embodiment, the air outlet connecting arm unit 21 of the air guide-air outlet assembly 2 is provided with two units, which are arranged on both sides of the host-air inlet assembly 1.

[0036] Please see Figures 1-5 In some possible embodiments, the air outlet housing unit 22 is an annular closed structure, and the end air guide space 30 within the air outlet housing unit 22 is also an annular closed structure. Setting the air outlet housing unit 22 and the end air guide space 30 as annular closed structures serves two purposes: firstly, it provides sufficient volume for the end air guide space 30, allowing the airflow to flow fully and evenly within it, thus making the airflow ejected from the air outlet 221 more uniform and gentle; secondly, it provides sufficient area for the air outlet 221, increasing the air outlet area of ​​the air outlet mechanism. Figure 1 , Figure 4 and Figure 5 As shown, in this embodiment, each air outlet connecting arm unit 21 swings along the pitch direction with the same direction and angular velocity.

[0037] Please refer to the figure. Figure 6 and Figure 7In some other possible embodiments, each air outlet connecting arm unit 21 is provided with an air outlet shell unit 22 at its free end. In this embodiment, each air outlet connecting arm unit 21 can swing in the same direction and angular velocity along the pitch direction, or swing in different directions or angular velocities along the pitch direction, so that the air outlets 221 of each air outlet shell unit 22 point in different directions, thereby obtaining more air outlet angles at the same time.

[0038] More specifically, the air outlet 221 of the air outlet shell unit 22 is at least one of the following: a strip structure, a mesh structure, a dot matrix hole structure, and a ring-shaped closed structure; in this embodiment, the air outlet 221 of the air outlet shell unit 22 is a strip structure.

[0039] Please see Figure 3 and Figure 7 Furthermore, an air distribution shell 13 is provided in the initial air guiding space 10 of the main unit housing 11. The air distribution shell 13 is an engineering plastic shell with an opening, which is fixed in the initial air guiding space 10 of the main unit housing 11 by means of snap-fit ​​or interference fit. The air distribution shell 13 is used to guide the airflow from the fan device 12 to the intermediate air guiding space 20 of each air outlet connecting arm unit 21 of the air guiding-air outlet assembly 2. In this embodiment, the air distribution shell 13 has a single air inlet opening and two air outlet openings, so that air can be drawn in from the fan device 12 and distributed to each air outlet connecting arm unit 21 of the air guiding-air outlet assembly 2.

[0040] More specifically, an air guide rib 131 is formed in the air guide distribution shell 13. The air guide rib 131 is a feature structure integrally formed on the inner wall of the air guide distribution shell 13. The air guide rib 131 bulges towards the fan device 12 and slopes down towards each air outlet connecting arm unit 21.

[0041] Please see Figure 1 , Figure 2 and Figure 6Furthermore, one end of the main unit housing 11 of the main unit-air intake assembly 1 is provided with an interactive panel 112. The interactive panel 112 is one of a touch interactive panel (with or without a display module), a mechanical interactive panel (with or without a display module), and a display panel with an infrared receiver (for receiving infrared remote control signals). It can control the opening / closing and speed of the fan device 12. The interactive panel 112 has a cover-shaped outer contour and is coaxially fixedly connected (e.g., fastened) to the main unit housing 11. In this embodiment, the interactive panel 112, the air intake vent unit 111, and the main unit housing 11 are all independently provided and sequentially fixedly connected along the same axis. The extension direction of the air outlet connecting arm unit 21 of the air guide-air outlet assembly 2 is the same as the extension direction of the main unit housing 11 of the main unit-air intake assembly 1, so that the air outlet 221 at the air outlet housing unit 22 and the interactive panel 112 at the main unit housing 11 face the same direction.

[0042] Please see Figure 3 or Figure 7 In this embodiment, when the fan device 12 is running, the air outlet mechanism can drive the airflow from the air inlet grille unit 111 into the main unit housing 11 of the main unit-air inlet assembly 1, and run along the initial air guide space 10 into the air guide distribution shell 13. When the airflow contacts the air guide ribs 131 of the air guide distribution shell 13, the air guide ribs 131, which slope down towards the two air outlet connecting arm units 21 respectively, can guide the airflow and distribute the airflow roughly evenly to the middle air guide space 20 of the two air outlet connecting arm units 21 of the air guide-air outlet assembly 2. The airflow continues to run along the path of the middle air guide space 20 and the end air guide space 30 until it is jetted out from the air outlet 221 of the air outlet shell unit 22.

[0043] The air outlet mechanism of this embodiment has at least the following hydrodynamic and mechanical characteristics:

[0044] 1. When the air outlet housing unit 22 and the terminal air guide space 30 are set as an annular closed structure, firstly, it provides sufficient volume for the terminal air guide space 30 so that the airflow can flow fully and evenly in the terminal air guide space 30, thereby making the airflow jetted out at the air outlet 221 more uniform and gentle; secondly, it provides sufficient area for the air outlet 221, increasing the air outlet area of ​​the air outlet mechanism.

[0045] 2. When each air outlet connecting arm unit 21 is provided with an air outlet shell unit 22 at its free end, each air outlet connecting arm unit 21 can swing in the pitch direction in the same direction and angular velocity, or swing in the pitch direction in different directions or angular velocities, so that the air outlet 221 of each air outlet shell unit 22 points in different directions, thereby obtaining more air outlet angles at the same time.

[0046] 3. The air outlet connecting arm unit 21 of the air guide-air outlet assembly 2 is set to several, firstly to provide ample intermediate air guide space 20 so that the airflow can flow smoothly in several intermediate air guide spaces 20, thereby making the airflow entering the terminal air guide space 30 more uniform, and secondly to provide a mechanical support structure with better balance and stability for the air outlet shell unit 22.

[0047] 4. In the air distribution shell 13, the air guide ribs 131 that slope down towards each air outlet connecting arm unit 21 can guide the airflow and distribute the airflow roughly evenly to the middle air guide space 20 of each air outlet connecting arm unit 21 of the air guide-air outlet assembly 2.

[0048] Furthermore, in this embodiment, the air outlet mechanism has an interactive panel 112 located at one end of the main unit housing 11 of the main unit-air inlet assembly 1. When the air guide-air outlet assembly 2 swings in the pitch direction, the interactive panel 112 remains stationary, so that the interactive panel 112 can always face the user and is not affected by the movement of the air guide-air outlet assembly 2, thereby improving the convenience for the user when operating the interactive panel 112.

[0049] Furthermore, in this embodiment, the air outlet mechanism has an interactive panel 112 located at one end of the main unit housing 11 of the main unit-air intake assembly 1, which makes the interactive panel 112 closer to the installation position of the fan device 12, thereby shortening the cable routing distance (whether it is a power line or a data line). Compared with fans that need to rely on the mesh cover for cable routing, the air outlet mechanism of this embodiment has the characteristics of shorter routing distance and simpler routing process.

[0050] Please see Figures 1-3 This embodiment also provides a fan, which includes the above-described air outlet mechanism.

[0051] Specifically, the fan in this embodiment also includes a base-support mechanism 3, which is used to support the host-air intake assembly 1. In this embodiment, the base-support mechanism 3 includes a base and a pole. The host housing 11 of the host-air intake assembly 1 is fixed / pivoted to the top of the pole, so that the base-support mechanism 3 can support the host-air intake assembly 1.

[0052] In this embodiment, the air outlet mechanism and the fan using it are such that the fan device 12 can drive the airflow from the air inlet grille unit 111 into the main unit housing 11 of the main unit-air inlet assembly 1, and run along the path of the initial air guide space 10, the intermediate air guide space 20 and the terminal air guide space 30 until it is ejected from the air outlet 221 of the air outlet housing unit 22. This embodiment provides the fan with good hydrodynamic and mechanical characteristics, so that the fan has excellent functions such as wide-angle air outlet, ventilation and air exchange and equalization of indoor temperature, while also obtaining excellent characteristics such as beautiful appearance, gentle airflow, high safety (fan blades are not exposed) and fan blades are not easy to accumulate dust. That is, it integrates the advantages of air circulation fans and bladeless fans, and overcomes some of the disadvantages of air circulation fans and bladeless fans.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
