In the description of the present application, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," etc. indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, are merely for convenience in describing the present application and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be configured and operated in a particular orientation, and therefore should not be construed as limiting the present application.

Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" is at least two, such as two, three, etc., unless explicitly defined otherwise.

In this application, unless specifically stated and limited otherwise, the terms "mounted," "connected," "secured," and the like are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed; can be mechanically or electrically connected; either directly or indirectly, through intermediaries, or both, may be in communication with each other or in interaction with each other, unless expressly defined otherwise.

Different appearance structures are often required to be developed for different air outlet devices in the current industry, so that the universality among different air outlet devices is low, and the overall input-output ratio is low.

For example, the cooling and heating tower fan and the single cooling tower fan have two completely different configurations, the shell lengths are different, and the air port grids are different in length. The cooling and heating tower fan adopts two independent motor drives to respectively control and start a cold air mode and a warm air mode, and the single cooling tower fan only has one motor drive air outlet, so that the part difference of two products is large, and the production investment is increased. Therefore, the price difference between the cooling tower fan and the single cooling tower fan is often doubled, and the function integration can improve the utilization rate of products and reduce the space and socket requirements for consumers, but when the price exceeds too much, the purchasing desire of the consumers is greatly reduced, and the product sales is influenced.

For the air outlet device, the main requirement is to blow cold air, and the air outlet device is configured by a master pin. Therefore, most of air outlet devices in the market only have a single function of blowing cold air, and most of the air outlet devices can only be started in hot summer. However, in order to increase the use scene of the product, improve the use rate, exert the product value, meet the crowd of partial cold and warm demands, greatly reduce the investment, reduce the price of the composite product, and need to consider the common components of cold and warm and single cold products as much as possible, so that enterprises can reduce the investment, thereby developing products with various configurations, forming a product sales matrix, improving the competitiveness, reducing the selling price of the composite product and providing products with higher cost performance for consumers.

Based on the above consideration, the applicant has conducted intensive research and has designed an air-out device, and the aircraft nose can adapt first base or second base respectively to make air-out device can select to adopt first base or second base according to market demand, thereby realize the first air-out mode or the second air-out mode of air-out device. Therefore, in the development and production process of the air outlet device, the input cost can be greatly reduced, so that the selling price of the air outlet device is correspondingly reduced, and the cost performance of the air outlet device is higher.

Referring to fig. 1, 2 and 3, an air outlet device 100 according to an embodiment of the present disclosure includes a machine head 10, a first base 20, a second base 30 and an air supply assembly 40. The machine head 10 is provided with a first air inlet 11 and a first air supply outlet 12 which are mutually communicated, the inside of the second base 30 is provided with a first air duct 31 and a second air duct 32 which are mutually communicated and have different air outlet directions, the air supply assembly 40 is arranged in the first base 20 or the second base 30, and the air supply assembly 40 is internally provided with an air supply duct 41. The air-out device 100 has a first air-out mode and a second air-out mode. When the air outlet device 100 is in the first air outlet mode, the machine head 10 is detachably connected to the first base 20, and the air supply duct 41 is communicated with the first air inlet 11. When the air outlet device 100 is in the second air outlet mode, the machine head 10 is detachably connected to the second base 30, the first air duct 31 is connected between the air supply duct 41 and the first air inlet 11, and the second air duct 32 is connected between the air supply duct 41 and the external environment.

When the handpiece 10 is connected to the first base 20 or the second base 30, the handpiece 10 is detachably disposed above the first base 20 or the second base 30. Therefore, when the air outlet device 100 is in the second air outlet mode, the outlet of the second air duct 32 is located below the first air outlet 12, so that the first air outlet 12 can supply air at a higher position, and the outlet of the second air duct 32 can supply air at a lower position, so as to meet the air blowing requirements of different positions of users.

The first air duct 31 in the second base 30 is different from the second air duct 32 in the arrangement direction, specifically, the first air duct 31 may be arranged along the vertical direction, that is, the outlet of the first air duct 31 is opened upwards. Correspondingly, a first air inlet 11 on the machine head 10 is opened downwards. When the machine head 10 is detachably connected with the second base 30, the outlet of the first air duct 31 is tightly connected with the first air inlet 11.

The second air duct 32 may be disposed along a horizontal direction, that is, the outlet of the second air duct 32 is opened along the horizontal direction, so that the air flow in the second air duct 32 may be blown out along the horizontal direction.

The air outlet device 100 of the present application can select one of the first air outlet mode and the second air outlet mode according to market demands, when the air outlet device 100 is required to work in the first air outlet mode, the machine head 10 is detachably connected with the first base 20, and the air supply assembly 40 can be accommodated inside the first base 20, so that the air supply duct 41 is tightly communicated with the first air inlet 11 on the machine head 10.

When the air outlet device 100 is required to operate in the second air outlet mode, the machine head 10 is detachably connected with the second base 30, and the air supply assembly 40 can be accommodated inside the second base 30, so that the air supply assembly 40 is respectively communicated with the first air duct 31 and the second air duct 32. The first air duct 31 may be configured to communicate the air supply duct 41 with the first air inlet 11, and after the air flow is generated in the air supply duct 41, the air flow may enter the first air inlet 11 through the first air duct 31 and then be blown out from the first air supply port 12 or be blown out from the second air duct 32.

Therefore, the parts such as the machine head 10 and the air supply assembly 40 in the air outlet device 100 have good universality, and the first base 20 or the second base 30 can be selected for assembly according to market demands, so that different configurations of the air outlet device 100 can be realized, thereby greatly reducing the production input cost of the air outlet device 100 and improving the cost performance of the air outlet device 100.

Referring to fig. 1, 2 and 4, in some embodiments, the second base 30 includes a base 33 and an air outlet main body 34 detachably assembled inside the base 33, and the base 33 is provided with a second air outlet 331. The air outlet main body 34 is provided with a second air inlet 341, a first air outlet 342 and a second air outlet 343, a first air channel 31 is defined between the second air inlet 341 and the first air outlet 342, and a second air channel 32 is defined between the second air inlet 341 and the second air outlet 343 as well as between the second air outlet 331.

Specifically, the base 33 has an inner cavity, the air outlet main body 34 can be accommodated in the inner cavity, and the base 33 can be detachably connected with the machine head 10.

The base 33 may be detachably connected to the handpiece 10 by a connection method such as a bolt connection or a snap connection. In addition, when the first base 20 is detachably connected to the machine head 10, the connection manner of the first base may be a bolt connection or a snap connection, which will not be described herein.

The air outlet main body 34 is configured as a hollow structure, and the second air inlet 341, the first air outlet 342 and the second air outlet 343 are respectively formed on the air outlet main body 34, so that the first air channel 31 is defined between the second air inlet 341 and the first air outlet 342. When the air outlet main body 34 is accommodated in the inner cavity of the base 33, the second air outlet 343 on the air outlet main body 34 is at least partially disposed corresponding to the second air outlet 331 on the base 33, so that the air flow blown out from the second air outlet 343 can be smoothly blown out from the second air outlet 331 to the external environment.

The air flow enters the air outlet main body 34 through the second air inlet 341, and is blown out to the external environment through the second air outlet 343 and the second air outlet 331, so that the second air inlet 341 and the second air outlet 343 and the second air outlet 331 together define a second air duct 32 through which the air flow passes.

Through setting up air-out main part 34, can make the air current blow out from first wind channel 31 or second wind channel 32 with different directions to realize the multi-angle diversified air-out of wind device 100, make air-out device 100 can be adapted to more service scenarios.

In some embodiments, the air outlet device 100 further includes a heating element 50, where the heating element 50 is detachably disposed inside the air outlet main body 34 and located on a path of the airflow flowing out from the second air outlet 343.

Specifically, the heating element 50 is disposed between the second air inlet 341 and the second air outlet 343, and air flows from the second air inlet 341 into the air outlet main body 34 and is blown from the second air outlet 343 to the second air outlet 331, and in this process, the heating element 50 heats the air flow passing through itself, thereby achieving the effect of blowing warm air from the second air outlet 331.

By arranging the heating element 50 in the second air duct 32, cold air and warm air can be blown out of the first air duct 31 and the second air duct 32 respectively, so that the air outlet device 100 can meet different requirements of cold air blowing and warm air blowing.

Further, the heating element 50 may be detachably disposed inside the air outlet main body 34 by a snap connection, and of course, the heating element 50 may be detachably disposed inside the air outlet main body 34 by other manners such as a bolt connection.

Further, as a specific embodiment, the heating member 50 may be provided as a PTC heating device. Of course, the heating element 50 may be configured as other heating structures, which will not be described herein.

In some embodiments, the air outlet device 100 further includes a switching assembly 60 disposed on the air outlet main body 34, where the switching assembly 60 is movably connected to the air outlet main body 34 to selectively close the first air duct 31 or the second air duct 32.

Specifically, when the switching assembly 60 closes the first air duct 31, the second air duct 32 is in a connected state. The air flow in the air supply duct 41 enters the second air duct 32, and the heating element 50 heats the air flow in the second air duct 32, and the heated air flow is blown out from the second air supply port 331, thereby achieving the effect of warm air.

When the switching assembly 60 closes the second air duct 32, the first air duct 31 is in a connected state. The air flow in the air supply duct 41 enters the first air inlet 11 through the first air duct 31 and is blown out from the first air supply port 12, so that the effect of cold air is achieved.

Therefore, when the air-out device 100 is in the second air-out mode, the switching assembly 60 can selectively close the first air duct 31 and the second air duct 32, so as to realize two air-out modes of air-out and warm air-out. That is, when the air-out device 100 is in the second air-out mode, the air-out device 100 is the dual-purpose air-out device 100 for cooling and heating.

As can be appreciated, when the air outlet device 100 is in the first air outlet mode, since the air supply duct 41 is directly communicated with the first air inlet 11, the air flow in the air supply duct 41 enters the first air inlet 11 and is blown out from the first air supply outlet 12, thereby achieving the effect of cooling air. That is, when the air-out device 100 is in the first air-out mode, the air-out device 100 is a single-cooled air-out device 100.

Through the above structure, in the production process of the air-out device 100, one of the first base 20 or the second base 30 can be selected to be detachably connected with the machine head 10 according to market demands, so as to provide the dual-purpose air-out device 100 for cooling and heating or the single-cooling air-out device 100 correspondingly. Thus, the investment of production cost can be effectively reduced.

Referring to fig. 5, in some embodiments, the switching assembly 60 includes a rotating shaft 61 and a baffle 62 disposed on the rotating shaft 61, wherein the rotating shaft 61 is rotatably disposed inside the air outlet main body 34, and drives the baffle 62 to alternatively close the first air duct 31 or the second air duct 32.

Specifically, the inner wall of the air outlet main body 34 is provided with a shaft hole matched with the rotating shaft 61, and the opposite ends of the rotating shaft 61 along the axial direction of the rotating shaft can be controlled to rotate in the corresponding shaft holes, so that the baffle plate 62 is driven to synchronously rotate.

The outer contour of the baffle plate 62 matches the contours of the first air outlet 342 and the second air outlet 343, and the baffle plate 62 can be respectively arranged corresponding to the first air outlet 342 or the second air outlet 343 in the process of rotating along with the rotating shaft 61.

When the baffle 62 rotates to be disposed corresponding to the first air outlet 342, the baffle 62 seals the first air outlet 342, thereby closing the first air duct 31. At this time, the second air duct 32 is connected, and the air flow in the air supply duct 41 is heated by the heating element 50, and then the warm air is blown out from the second air duct 32.

When the baffle plate 62 rotates to be disposed corresponding to the second air outlet 343, the baffle plate 62 seals the second air outlet 343, thereby closing the second air duct 32. At this time, the first air duct 31 is communicated, and the air flow in the air supply duct 41 enters the first air inlet 11 through the first air duct 31, and blows out cold air from the first air blowing port.

Therefore, the baffle plate 62 can be driven to rotate through the rotating shaft 61, so that the cold air mode and the warm air mode can be switched rapidly.

Referring to fig. 5, 6 and 7, in some embodiments, a sliding slot 344 is formed on an inner wall of the air outlet main body 34, a sliding column 621 matching with the sliding slot 344 is protruding on the baffle plate 62, and the sliding column 621 slides along the sliding slot 344, so that the baffle plate 62 can selectively close the first air outlet 342 or the second air outlet 343.

During the rotation of the shutter 62 following the rotation shaft 61, the slide posts 621 on the shutter 62 slide along the slide grooves 344. On the one hand, the process of the shutter 62 rotating along with the rotation shaft 61 can be made more stable. On the other hand, the baffle 62 can be provided to correspond to the first air outlet 342 or the second air outlet 343 accurately according to the path opened by the chute 344. When the baffle 62 is disposed corresponding to the first air outlet 342, the baffle 62 closes the first air outlet 342, i.e. the first air duct 31. When the baffle plate 62 is disposed corresponding to the second air outlet 343, the baffle plate 62 closes the second air outlet 343, i.e. the second air duct 32.

As a specific embodiment, the opening directions of the first air outlet 342 and the second air outlet 343 are perpendicular to each other and are arranged on the air outlet main body 34, the first air outlet 342 is arranged upwards, and the second air outlet 343 is arranged horizontally. Therefore, the chute 344 is formed on the inner wall of the air outlet main body 34 in a quarter arc shape, and when the sliding column 621 slides to the top points of the opposite ends of the chute 344, the baffle 62 is disposed corresponding to the first air outlet 342 or the second air outlet 343, so as to smoothly close the first air outlet 342 or the second air outlet 343.

Further, in order to facilitate installation, the air outlet main body 34 is split into a first split body and a second split body which are symmetrical to each other, and the first split body and the second split body enclose together to form a second air inlet 341, a first air outlet 342 and a second air outlet 343. In addition, the first split body and the second split body can be detachably connected through a buckle connection, a bolt connection or other connection modes.

The inner walls of the first split body and the second split body facing each other are respectively provided with shaft holes and sliding grooves 344 symmetrically arranged, so that the rotating shaft 61 and the baffle 62 can be stably arranged inside the air outlet main body 34, and the baffle 62 can rotate more stably along with the rotating shaft 61.

Referring to fig. 1 and 4 again, in some embodiments, the switching assembly 60 further includes a first driving member 63 in driving connection with the rotating shaft 61, and the first driving member 63 is used for driving the rotating shaft 61 to rotate.

Specifically, the first driving member 63 may be configured as a driving motor, and the rotating shaft 61 is provided with a coupling hole along one of its axial end surfaces, which is matched with the driving shaft of the first driving member 63, and the driving shaft of the first driving member 63 is inserted into the coupling hole, thereby driving the rotating shaft 61 to rotate about its axis.

In some embodiments, the second base 30 further includes a grille member 35, and the grille member 35 is detachably disposed in the second air supply opening 331.

Specifically, a buckle may be disposed on an inner wall of the second air supply port 331, and a slot is disposed on an outer periphery of the grille member 35 in the buckle fit, so that the grille member 35 is detachably disposed in the second air supply port 331.

Of course, the grille member 35 may be detachably disposed in the second air outlet 331 by other connection methods such as bolting, which will not be described herein.

The grille member 35 is disposed in the second air supply opening 331, and can filter the larger contaminants in the external environment, thereby protecting the structure inside the second base 30.

In some embodiments, the air supply assembly 40 includes a volute 42 and a wind wheel 43, wherein the wind wheel 43 is disposed in the volute 42 and can rotate around itself to form the air supply duct 41 inside the volute 42.

The wind wheel 43 rotates around itself to generate air flow, and the air flow can enter the first air inlet 11 or the air outlet main body 34 through the air supply duct 41, so as to realize air outlet from the first air supply port 12 or the second air supply port 331.

As a specific embodiment, to facilitate the installation of the air supply assembly 40, the volute 42 is split into a first housing and a second housing that are symmetrical to each other, the first housing and the second housing are detachably connected by a snap connection, a bolt connection, or other connection means, and the wind wheel 43 is accommodated between the first housing and the second housing. When the wind wheel 43 rotates, the air supply duct 41 is formed between the first casing and the second casing.

In some embodiments, the blower assembly 40 further includes a second driving member 44 drivingly connected to the wind wheel 43, and the second driving member 44 is configured to drive the wind wheel 43 to rotate.

The second drive member 44 may be provided as a drive motor and is in driving connection with the wind wheel 43. Specifically, a through hole is formed in the first casing or the second casing, so that the driving shaft of the second driving member 44 can pass through the through hole and is in driving connection with the wind wheel 43 inside the volute 42, so as to drive the wind wheel 43 to rotate.

In some embodiments, the air outlet device 100 further includes a base 70, and the air supply assembly 40 is detachably disposed on the base 70. When the air-out device 100 is in the first air-out mode, the first base 20 is connected between the machine head 10 and the base 70. When the air-out device 100 is in the second air-out mode, the second base 30 is connected between the machine head 10 and the base 70.

As shown in fig. 3, when the air outlet device 100 is in the first air outlet mode, the air supply assembly 40 is first disposed on the base 70, and then the base 70 and the air supply assembly 40 are connected together with the lower end of the first base 20, so that the first base 20 is covered on the air supply assembly 40, and the upper end of the first base 20 is detachably connected with one end of the first air inlet 11 of the machine head 10, thereby completing the assembly of the air outlet device 100 in the first air outlet mode. At this time, the air flow in the air supply assembly 40 enters the first air inlet 11 from the air supply duct 41, and blows out the cold air from the first air supply opening 12, thereby realizing the single cooling mode.

As shown in fig. 2, when the air-out device 100 is in the second air-out mode, the air-supply assembly 40 is first disposed on the base 70, and then the base 70 and the air-supply assembly 40 are connected together with the lower end of the second base 30, such that the second base 30 is covered on the air-supply assembly 40, and the upper end of the second base 30 is detachably connected with one end of the first air inlet 11 of the machine head 10, thereby completing the assembly of the air-out device 100 in the second air-out mode.

At this time, the rotation shaft 61 is controlled to drive the baffle 62 to rotate, so that the baffle 62 closes the first air outlet 342, and the second air outlet 343 is opened. The air flow in the air supply duct 41 enters the second air duct 32 from the second air inlet 341, forms warm air under the heating action of the heating element 50, and is blown out through the second air outlet 343 and the second air supply outlet 331 on the second base 30, thereby realizing a warm air mode.

When the shutter 62 rotates along with the rotation shaft 61 and closes the second air outlet 343, the first air outlet 342 is opened. The air flow in the air supply duct 41 enters the first air duct 31 from the second air inlet 341, enters the first air inlet 11 from the first air outlet 342, and finally blows out cold air from the first air supply port 12 on the machine head 10, thereby realizing a cold air mode.

Based on the same concept as the air outlet device 100, the application also provides a bladeless fan, including the air outlet device 100.

When the air outlet device 100 with the single cooling mode is required to be assembled, the air supply assembly 40 is arranged on the base 70, and the base 70 and the air supply assembly 40 are connected with the lower end of the first base 20 together, so that the first base 20 is covered on the air supply assembly 40. Then, the upper end of the first base 20 is detachably connected with one end of the machine head 10 provided with the first air inlet 11, so that the outlet of the air supply duct 41 can be in butt joint with the first air inlet 11.

The air flow in the air supply duct 41 enters the machine head 10 through the first air inlet 11, and cold air is blown out from the first air supply opening 12 formed in the machine head 10.

When the air-out device 100 with two air-out modes of cooling and heating is required to be assembled, the air-out assembly 40 is arranged on the base 70, and the base 70 and the air-out assembly 40 are connected with the lower end of the second base 30 together, so that the second base 30 is covered on the air-out assembly 40. Then, the upper end of the second base 30 is detachably connected with one end of the machine head 10 provided with the first air inlet 11, so that the first air outlet 342 on the air outlet main body 34 is in butt joint with the first air inlet 11.

The air outlet device 100 at this time has both the cool air mode and the warm air mode. When the cold air mode is opened, the baffle 62 rotates along with the rotating shaft 61 and closes the second air outlet 343, at this time, the first air outlet 342 is opened, the air flow in the air supply duct 41 enters the first air duct 31 from the second air inlet 341, enters the first air inlet 11 from the first air outlet 342, and finally blows out cold air from the first air supply port 12.

When the warm air mode is opened, the baffle 62 rotates along with the rotating shaft 61 and closes the first air outlet 342, at this time, the second air outlet 343 is opened, the air flow in the air supply duct 41 enters the second air duct 32 from the second air inlet 341, and warm air is formed under the heating action of the heating element 50 and blown out from the first air supply port 12.
