[0032] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application based on the specific content of the technical solution.

[0033] Reference Figures 1 to 9 The embodiment of the present application provides a bladeless fan, comprising: a base 100; a fan assembly, comprising a first shell 210 and an air supply member 220, the first shell 210 is connected to the base 100 through a first driving member 230, so that the first shell 210 can shake its head relative to the base 100, the first shell 210 is provided with an air inlet 211 and a vent 212, the air supply member 220 is arranged in the first shell 210, and the air inlet 211 is connected to the vent 212 through the air supply member 220; an air duct assembly, comprising a second shell 310, a wind shield 320 and a second driving member 330, the second shell 310 and the first shell 2 10 is connected, the second shell 310 is provided with a accommodating cavity 311, the accommodating cavity 311 is communicated with the vent 212, a plurality of air outlets 312 are arranged on the circumference of the second shell 310, the air outlets 312 are communicated with the accommodating cavity 311, the wind shield 320 corresponds to the air outlet 312 one by one, a second driving member 330 is provided on the second shell 310, the second driving member 330 is connected with the wind shield 320, and the second driving member 330 drives the wind shield 320 to open or close the air outlet 312; wherein, when the plurality of air outlets 312 are all opened, the first shell 210 can realize 360° air outlet by shaking its head relative to the base 100.

[0034] During use, the user can select the corresponding air outlet 312 to discharge air according to the use demand. At this time, the second driving member 330 drives the wind shield 320 to open the corresponding air outlet 312, and the air outlet 312 that does not need to be discharged is closed by the wind shield 320. The wind enters the accommodating cavity 311 from the air inlet 211 through the vent 212 under the action of the air supply member 220, and is finally blown out from the opened air outlet 312, thereby avoiding the trouble caused by the manual movement of the fan in the related technology. At the same time, the air outlet 312 can also be made to discharge air toward the corresponding position to prevent the waste of resources in the unmanned area. Since a plurality of air outlets 312 are provided, a plurality of air outlets 312 can be selected to discharge air at the same time, thereby increasing the air outlet area and ensuring that users at different positions are affected by the wind. The user experience is improved; by shaking the first shell 210 relative to the base 100, the first shell 210 drives the air outlet 312 to shake, thereby increasing the air outlet area, and can also cooperate with multiple air outlets 312 to reduce the shaking angle of the first shell 210 and the base 100, shorten the waiting time period, increase the frequency of wind exposure for the user, and improve the air outlet effect; when the multiple air outlets 312 are all opened and the first shell 210 shakes its head relative to the base 100, 360° air outlet can be achieved, thereby preventing the safety risks caused by the 360° rotation and entanglement of the power cord, improving the safety of the product, and at the same time shortening the waiting time period, increasing the frequency of wind exposure for the user, and improving the user experience.

[0035] Reference Figure 2 In this embodiment, the air supply member 220 is configured as a centrifugal wind wheel, and a pressurized chamber 221 is provided in the air supply member 220. When the air supply member 220 is working, wind enters from the air inlet 211, increases the wind pressure through the pressurized chamber 221, then enters the accommodating chamber through the vent 212, and finally blows out from the air outlet 312. By providing the pressurized chamber 221, the wind pressure can be increased, so that the wind blown out of the air outlet 312 can be blown farther, the wind receiving distance is extended, and the user experience is improved.

[0036] It should be noted that in some other embodiments, the air supply member 220 can also be set to other structures besides the centrifugal wind wheel, such as a circulating fan, etc., which can also achieve the effect of sucking air from the air inlet 211 and discharging it from each air outlet 312, which will not be elaborated here.

[0037] Reference Figure 2In this embodiment, the air supply member 220 is provided with a first connecting cavity 222, which is connected to the pressurizing cavity 221, and the cross-sectional area of ​​the first connecting cavity 222 gradually increases toward the end. In the related art, in order to reduce the effect of air outlet caused by the increase in the number of air outlets, the wind pressure is usually deliberately increased, such as increasing the speed of the air blower, but the noise caused by this is always unavoidable. Therefore, by gradually increasing the cross-sectional area of ​​the first connecting cavity 222 toward the end, it can accommodate more air volume and reduce the generation of noise. It can be imagined that a second connecting chamber 213 is provided on the upper part of the first shell 210, one end of the second connecting chamber 213 is connected to the first connecting chamber 222, and the vent 212 is provided at the other end of the second connecting chamber 213, and the second connecting chamber 213 is connected to the accommodating chamber 311 through the vent 212, and the cross-sectional area of ​​the second connecting chamber 213 gradually decreases toward the side of the accommodating chamber 311, so that the first connecting chamber 222 and the second connecting chamber 213 can jointly accommodate more air volume, and at the same time, it can also increase the thrust of wind entering the accommodating chamber 311, and increase the wind pressure of the accommodating chamber 311, thereby ensuring that when multiple air outlets 312 are opened, the air outlet rate of the air outlet 312 is large, thereby extending the wind receiving distance. Furthermore, the air outlet 312 is configured as a thin and long strip structure, and the air outlet 312 is configured to spiral upward along the axis of the second shell 310, so that the wind in the accommodating cavity 311 can be pushed out of the air outlet 312 spirally, so that the wind pressure can be further increased when the wind in the accommodating cavity 311 is discharged from the air outlet 312, the wind receiving distance can be extended, the wind discharge effect can be improved, and the wind receiving area can also be increased, thereby enhancing the wind discharge effect. By adopting the above configuration, it is possible to ensure that the wind speed of multiple air outlets is increased while reducing the generation of noise, thereby improving the user experience.

[0038] Reference Figure 1 and Figure 2In some embodiments, the bladeless fan further includes a control component, the control component includes a button controller 400, the button controller 400 is disposed on the top of the second shell 310, and the button controller 400 is electrically connected to the first driving member 230 and the second driving member 330 respectively. Specifically, when the user needs to open one or more of the air outlets 312 and does not need to shake the head, the button controller 400 will output a first signal, the button controller 400 receives the first signal and drives the corresponding second drive member 330 according to the first signal, so that the second drive member 330 drives the wind shield 320 to rotate to open the air outlet 312, thereby achieving the air outlet effect; when one or more of the air outlets 312 need to be opened and the head needs to be shaken, the button controller 400 will output a first signal, the button controller 400 receives the first signal and drives the corresponding second drive member 330 according to the first signal, so that the second drive member 330 drives the wind shield 320 to rotate to open the air outlet 312, and at the same time, the button controller 400 will also output a second signal, the button controller 400 receives the second signal and drives the first drive member 230 according to the second signal, so that the first shell 210 shakes its head relative to the base 100, thereby achieving the shaking head air outlet effect.

[0039] It is conceivable that the control component also includes an angle sensor, which is used to detect the shaking angle of the first shell 210. When performing the shaking action, in order to avoid wasting resources, the shaking angle of the first shell 210 can be pre-set through the key controller 400, and then the shaking angle of the first shell 210 is detected by the angle sensor and the first shell 210 is shaken at the set shaking angle, thereby adjusting the shaking angle of the first shell 210 to meet the different usage needs of users and adapt to different usage occasions. For example, a smaller shaking angle can be used when there are fewer people, and a larger shaking angle can be used when there are more people.

[0040] Reference Figure 3Specifically, the second housing 310 is provided with three air outlets 312 at three locations A, B, and C, and the shaking angle of the first housing 210 ranges from 0 to 120°. Among them, the three locations A, B, and C are respectively set at the midpoints of the movement paths of the three air outlets 312 and are set as the initial positions of the three air outlets 312, and the shaking angle of the first housing 210 is 60° left and right from the initial position. When air needs to be discharged from point A, the air outlet 312 at point A is opened, and the air outlets 312 at points B and C are closed. At this time, only point A can discharge air, while points B and C cannot discharge air. When air needs to be discharged from both points A and B, the air outlets 312 at points A and B are opened, and the air outlet 312 at point C is closed. At this time, both points A and B can discharge air simultaneously, while point C cannot discharge air. When the air outlets 312 at points A, B, and C are all opened, and the first housing 210 performs a shaking motion at the same time, and the shaking angle of the first housing 210 is 120°, 360° air discharge can be achieved. Of course, when only point A discharges air, or when points A and B discharge air simultaneously, the first housing 210 can also perform a shaking motion simultaneously.

[0041] It should be noted that the above examples of only outlet A or only outlet A and B at the same time are only for the purpose of better demonstrating the use effect of having multiple air outlets 312, and do not indicate or imply that the present application can only outlet A or outlet A and B at the same time, and therefore cannot be understood as a limitation of the present application. In actual use, the air outlet 312 can also choose any one of the air outlets 312 of B and C to outlet air, or any two of the air outlets 312 of A, B, and C to outlet air at the same time, and the shaking angle of the first shell 210 can also be selected to be 60° or 90°, etc., and the initial position of the air outlet 312 can also be selected to be set at other positions of its movement path.

[0042] It is understandable that in some other embodiments, the number of the air outlets 312 may also be four or five, etc. The number of the air outlets 312 may be set according to specific circumstances and is not limited here.

The first driving member 230 drives the first gear 231 to rotate, so that the first gear 231 reciprocates along the tooth segment, thereby realizing that the first shell 210 drives the air outlet 312 to shake its head. It can be imagined that the limiting parts 120 are provided at both ends of the tooth segment, and the first gear 231 abuts against the limiting parts 120 to limit the shaking angle of the first shell 210. When the first gear 231 abuts against the limiting part 120, the first driving member 230 drives the first gear 231 to rotate in the opposite direction, so that the first gear 231 returns along the tooth segment, thereby realizing the shaking effect.

[0044] It should be noted that the first driving member 230 can also be disposed on the base 100, and the first driving member 230 is directly connected to the first shell 210, and the first driving member 230 directly drives the first shell 210 to rotate, thereby realizing the shaking of the first shell 210, which has a simple structure and is easy to operate.

[0049] Reference Figure 6 and Figure 7 The second housing 310 includes a plurality of housing parts 314, which are mutually buckled and connected, and the air outlet 312 is provided at the housing part 314. By dividing the second housing 310 into a plurality of housing parts 314, the housing parts 314 and the corresponding windshields 320 can be formed into a modular housing during assembly, and then the modular housings are mutually matched and connected to form the entire air duct assembly, which not only facilitates the formation of the air duct assembly, but also facilitates the installation of the windshield 320, has a simple structure, and improves installation efficiency.
