Referring to fig. 1-5, an embodiment of the present application provides an air outlet device 100 for a bladeless fan 1000. The air outlet device 100 comprises a main body 10, a baffle 20 and a door assembly 30, wherein a first air duct 11 and a second air duct 12 with different air outlet directions are arranged in the main body 10. The shutter 20 is movably coupled to the main body 10 and is disposed corresponding to the first air duct 11 to controllably open or close the first air duct 11. Door assembly 30 is movably coupled to body 10 and is disposed in correspondence with second air duct 12 to controllably open or close second air duct 12.

It should be noted that, the air outlet device 100 provided in the present application may be used as a part of the bladeless fan 1000, and specifically, the bladeless fan 1000 includes a nose 200 and the air outlet device 100, and the nose 200 is disposed on the main body 10 of the air outlet device 100. The second air supply port 201 communicating with the first air duct 11 is opened on the machine head 200, so that the air flow in the first air duct 11 can be blown out from the second air supply port 201 on the machine head 200.

The main body 10 is internally provided with the first air duct 11 and the second air duct 12 with different air outlet directions, and when air flows respectively flow out of the first air duct 11 and the second air duct 12, different air supply directions can be formed, so that the air supply demands in more directions are met.

Specifically, the first air duct 11 may be disposed above the second air duct 12, so that the upper air blowing is achieved through the first air duct 11, the lower air blowing is achieved through the second air duct 12, and different use requirements of users are met.

Further, the shutter 20 can controllably open or close the first air duct 11, while the door assembly 30 can controllably open or close the second air duct 12. That is, the baffle 20 and the door assembly 30 can respectively and independently complete the opening and closing of the first air duct 11 and the second air duct 12, and the two air ducts are not mutually influenced.

Thus, during use, a user may choose to open the first air duct 11 via the baffle 20 and close the second air duct 12 via the door assembly 30, where only the first air duct 11 is blown, and localized blowing above may be achieved. Of course, the user may choose to close the first air duct 11 by the baffle 20 and open the second air duct 12 by the door assembly 30, and only the second air duct 12 supplies air at this time, so that the lower local air blowing can be realized. In addition, the user may also choose to open the first air duct 11 through the baffle 20 and open the second air duct 12 through the door assembly 30, and at this time, the first air duct 11 and the second air duct 12 supply air simultaneously, so that the air supply range of the air outlet device 100 is larger.

Accordingly, the baffle 20 and the door assembly 30 are respectively matched with the first air duct 11 and the second air duct 12, so that the air outlet device 100 can have an air outlet mode with more directions and more angles, and the air supply range of the air outlet device 100 can be enlarged.

Referring to fig. 3, fig. 6, and fig. 7 together, in some embodiments, the main body 10 includes a base 13 and an air outlet assembly 14 assembled inside the base 13, the base 13 is provided with a first air outlet 131, and the air outlet assembly 14 is provided with a first air inlet 141, a first air outlet 142, and a second air outlet 143. The first air inlet 141 and the first air outlet 142 define a first air channel 11 therebetween, and the first air inlet 141, the second air outlet 143 and the first air outlet 131 together define a second air channel 12 therebetween.

Specifically, the base 13 has an inner cavity, and the air outlet assembly 14 can be detachably connected with the wall of the inner cavity, so as to be accommodated in the inner cavity. For example, the air outlet assembly 14 may be detachably connected to the wall of the inner cavity by, but not limited to, bolting or snapping, so that the air outlet assembly 14 can be accommodated in the inner cavity.

Further, the air outlet assembly 14 is configured as a hollow structure, and the air outlet assembly 14 is provided with a first air inlet 141, a first air outlet 142 and a second air outlet 143, so that a first air channel 11 is defined between the first air inlet 141 and the first air outlet 142. When the air outlet assembly 14 is accommodated in the inner cavity of the base 13, the second air outlet 143 on the air outlet assembly 14 is at least partially disposed corresponding to the first air outlet 131 on the base 13, so that the air flow blown out from the second air outlet 143 can be smoothly blown out from the first air outlet 131 to the external environment.

The air flow enters the air outlet assembly 14 through the first air inlet 141 and is blown out to the external environment through the second air outlet 143 and the first air outlet 131 in sequence, so that the second air channel 12 through which the air flow passes is defined between the first air inlet 141 and the second air outlet 143 and between the first air outlet 131.

Through setting up air-out subassembly 14, can make the air current blow out from first wind channel 11 or second wind channel 12 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 addition, for ease of installation, the air outlet assembly 14 includes a first sub-piece and a second sub-piece. The first sub-component and the second sub-component are detachably connected through a bolt connection or a buckle connection, and the first sub-component and the second sub-component enclose together to form a first air inlet 141, a first air outlet 142 and a second air outlet 143.

In some embodiments, the air outlet device 100 further includes a heating element 40, where the heating element 40 is detachably disposed inside the air outlet assembly 14 and is located on a path of the airflow flowing out from the second air outlet 143.

Specifically, the heating element 40 is disposed between the first air inlet 141 and the second air outlet 143, and air flows into the air outlet assembly 14 from the first air inlet 141 and is blown to the first air outlet 131 from the second air outlet 143, and in this process, the heating element 40 heats the air flow passing through itself, so as to achieve the effect of blowing warm air from the second air outlet 201.

By arranging the heating element 40 in the second air duct 12, cold air and warm air can be blown out of the first air duct 11 and the second air duct 12 respectively, so that the air outlet device 100 can meet different requirements of cold air blowing and warm air blowing.

Further, the heating element 40 may be detachably disposed inside the air outlet assembly 14 by a snap connection, and of course, the heating element 40 may be detachably disposed inside the air outlet assembly 14 by other manners such as a bolt connection.

Further, as a specific embodiment, the heating member 40 may be provided as a PTC heating device. Of course, the heating element 40 may be configured in other heating structures, which will not be described herein.

Referring to fig. 6, 7 and 8, in some embodiments, the air outlet assembly 14 is provided with a first guiding portion 144, and the baffle 20 is provided with a first matching portion 21 that matches with the first guiding portion 144 to guide the baffle 20 to move relative to the air outlet assembly 14, so as to open or close the first air outlet 142.

Under the co-operation of the first guiding portion 144 and the first matching portion 21, the baffle 20 can move more stably relative to the air outlet assembly 14, and the opening or closing of the first air outlet 142 can be smoothly realized during the moving process.

In some embodiments, one of the first guiding portion 144 and the first engaging portion 21 includes a first sliding slot, and the other includes a sliding bar slidably engaged with the first sliding slot.

Specifically, the first guide portion 144 may include a first slide groove, and the first engaging portion 21 includes a slide bar slidably engaged with the first slide groove. I.e. the first chute is arranged on the air outlet assembly 14, and the slide bar is arranged on the baffle 20 at a position matched with the first chute. Therefore, the sliding strip can slide in the first sliding groove and drive the baffle 20 to move relative to the air outlet assembly 14 along the extending direction of the first sliding groove, so that the baffle 20 smoothly opens or closes the first air outlet 142.

It will be appreciated that the first guiding portion 144 may also include a slide bar, and the first engaging portion 21 includes a first sliding groove engaged with the slide bar. That is, the first sliding grooves are arranged on two opposite end surfaces of the baffle 20, and the sliding strips are arranged on the inner cavity wall of the air outlet assembly 14 to be matched with the first sliding grooves. Therefore, the sliding strip can also slide in the first sliding groove along the extending direction of the first sliding groove, so as to drive the baffle 20 to move relative to the air outlet assembly 14, and finally, the baffle 20 can smoothly open or close the first air outlet 142.

Of course, in some other embodiments, the first guiding portion 144 and the first engaging portion 21 may be configured as other guiding structures that are matched with each other, for example, the first guiding portion 144 is configured as a first sliding groove, and the first engaging portion 21 is configured as a roller or a ball that is engaged with the first sliding groove, so that the two rollers are engaged with each other, so as to drive the baffle 20 to move relative to the air outlet assembly 14 to open or close the first air outlet 142.

As shown in fig. 3, in some embodiments, the baffle 20 moves relative to the air outlet assembly 14 in a first direction a, and the first guide portion 144 cooperates with the first mating portion 21 to limit movement of the baffle 20 relative to the air outlet assembly 14 in a direction that intersects the first direction a. The first direction a is intersected with the opening direction of the first air outlet 142.

Specifically, the first direction a is intersected with the opening direction of the first air outlet 142, that is, the baffle 20 moves relative to the air outlet assembly 14 along the direction intersected with the opening direction of the first air outlet 142, so that the baffle 20 can smoothly open or close the first air outlet 142.

In the embodiment of the present application, the cooperation of the first guiding portion 144 and the first matching portion 21 is not limited to guiding the movement of the baffle 20 relative to the air outlet assembly 14, but also limiting the baffle 20 along the direction intersecting with the movement direction of the baffle 20, so as to avoid abnormal movement caused by dislocation between the first guiding portion 144 and the first matching portion 21.

Specifically, when one of the first guiding portion 144 and the first engaging portion 21 includes a first sliding groove, the other one of the first guiding portion and the first engaging portion includes a sliding strip slidably engaged with the first sliding groove, the sliding strip can abut against a groove wall of the first sliding groove along a direction intersecting with the moving direction of the baffle 20, so that the sliding strip can be limited in the first sliding groove.

In some embodiments, the air outlet device 100 further includes a first driving member 50 and a first transmission assembly 60, wherein the first driving member 50 is mounted on the base 13, and the first transmission assembly 60 is connected between the first driving member 50 and the baffle 20 for providing a driving force for moving the baffle 20 relative to the air outlet assembly 14.

Specifically, the first driving member 50 may be configured as a driving motor, and the first driving member 50 is detachably disposed on the inner cavity wall of the base 13 by means of bolting or buckling, etc., and the first driving member 50 can drive the first transmission assembly 60 to drive the baffle 20 to move relative to the air outlet assembly 14.

In some embodiments, the first transmission assembly 60 includes a first gear 61 and a first rack 62, the first gear 61 is in driving connection with the first driving member 50, the first rack 62 is disposed on the damper 20, and the first gear 61 is engaged with the first rack 62 to drive the damper 20 to move relative to the air outlet assembly 14.

By arranging the transmission mode that the first gear 61 and the first rack 62 are meshed with each other, the structure is simple, and the movement is more stable.

Specifically, the first driving member 50 has a driving shaft, and the first gear 61 is provided with a shaft hole which is fitted with the driving shaft, and the driving shaft is inserted into the shaft hole and is interference-fitted with the shaft hole, so that the first gear 61 can be prevented from being loosened.

Referring to fig. 3 and 9 together, in some embodiments, the base 13 is provided with a second guiding portion 132, and the door assembly 30 is provided with a second matching portion 31 that matches with the second guiding portion 132, so as to guide the door assembly 30 to move relative to the base 13, so as to open or close the first air outlet 131.

Under the co-operation of the second guide portion 132 and the second engaging portion 31, the door assembly 30 can move more stably relative to the base 13, and the opening or closing of the first air outlet 131 can be smoothly achieved during the movement.

Specifically, one of the second guiding portion 132 and the second engaging portion 31 includes a second sliding groove, and the other includes a roller that is in rolling engagement with the second sliding groove.

The roller is in rolling fit with the second chute so as to perform rolling friction between the roller and the second chute, so that certain power for enabling the door assembly 30 to move can be given in the movement of the door assembly 30 relative to the base 13, and further the timeliness and reliability of the movement are improved.

Further, when the roller is engaged with the second sliding groove in a rolling manner, one of the second guiding portion 132 and the second engaging portion 31 further includes a latch 32, and the roller is detachably mounted on the latch 32. When the roller is required to be mounted on the snap fastener 32, the snap fastener 32 deforms to enable the shaft hole of the roller to enter, and then the deformation is recovered, so that the roller is mounted in place. The installation mode is simple, and the roller can be conveniently replaced subsequently.

In addition, the end of the snap 32 is convexly provided with a locking portion, and the locking portion can lock the roller, thereby preventing the roller from falling off.

In some embodiments, one of the second guiding portion 132 and the second engaging portion 31 includes at least two rollers, and all the rollers are spaced apart from each other along the moving direction of the door assembly 30 relative to the base 13. In this way, the door assembly 30 is uniformly stressed in the guiding process of moving relative to the base 13, and the guiding reliability is improved.

As a specific embodiment, one of the second guiding portion 132 and the second engaging portion 31 includes two rollers. In some other embodiments, one of the second guiding portion 132 and the second engaging portion 31 may also include three rollers, four rollers, and so on, which may be reasonably arranged according to space.

In some embodiments, the second guiding portions 132 and the second mating portions 31 each include at least two, all the second guiding portions 132 are disposed at intervals, and all the second guiding portions 132 are mated with all the second mating portions 31 in a one-to-one correspondence. In this way, the movement of the door assembly 30 with respect to the base 13 can be made smoother.

Specifically, all of the second guide portions 132 are disposed at intervals from each other in a direction perpendicular to the moving direction of the door assembly 30 with respect to the base 13. Specifically, all the second guide portions 132 are disposed at intervals from each other in the direction perpendicular to the second direction b, that is, all the second guide portions 132 are disposed at intervals in the left-right direction shown in fig. 1.

As a specific embodiment, the second guiding portion 132 cooperates with the second mating portion 31, not only to guide the movement of the door assembly 30 relative to the base 13, but also to limit the movement of the door assembly 30 in a direction perpendicular to the movement direction of the door assembly 30 relative to the base 13, so as to avoid the door assembly 30 from being unable to move normally relative to the base 13 due to misalignment between the second guiding portion 132 and the second mating portion 31.

Specifically, the second guide portion 132 cooperates with the second engagement portion 31 to restrict the door assembly 30 from moving relative to the base 13 in a direction perpendicular to the second direction b.

In some embodiments, the second guide 132 is shielded by the door assembly 30 when the door assembly 30 moves to a position where the first air supply opening 131 is opened. Accordingly, the second guiding portion 132 is not exposed outside, which is beneficial to maintaining the overall aesthetic appearance of the air outlet device 100.

Further, the door assembly 30 moves relative to the base 13 along the second direction b, and the second guide 132 is located at one side of the first air supply opening 131 along the second direction b.
