[0036] As one specific embodiment of the present application, as Figures 1-4As shown, the embodiment provides an air treatment device 100, which can include a body 200 and an air outlet structure 300, the air outlet structure 300 being arranged above the body 200 and being rotatably connected with the body 200. The body 200 can include a purification assembly 210, a flow guide assembly 220, a driving member 230 and a first air guide member 240. The purification assembly 210 has an air inlet duct 211 therein. The flow guide assembly 220 is arranged at one side of the air inlet duct 211, and the flow guide assembly 220 is defined with a first air outlet duct 221 in communication with the air inlet duct 211. The first air outlet duct 221 has a first sub-air duct 2211 and a second sub-air duct 2212 formed at the end thereof. The gas entering the first air outlet duct 221 from the air inlet duct 211 flows through the first sub-air duct 2211 and then flows to the air outlet structure 300 and out, or flows through the first sub-air duct 2211 and the second sub-air duct 2212 and then flows out. The driving member 230 is arranged in the air inlet duct 211 or the first air outlet duct 221 and located at the front side of the first sub-air duct 2211 and the second sub-air duct 2212. The driving member 230 is controlled to rotate to drive the external gas to flow into the air inlet duct 211 and the first air outlet duct 221 from the purification assembly 210 and then flow out. The first air guide member 240 is arranged in the first air outlet duct 221 and located at the front side of the first sub-air duct 2211 and the second sub-air duct 2212, so that the gas in the first air outlet duct 221 is guided by the first air guide member 240 and then enters the first sub-air duct 2211 and the second sub-air duct 2212.

[0037] Specifically, the air treatment device 100 of the embodiment can include a machine body 200 and an air outlet structure 300, and the machine body 200 can further include a purification assembly 210, a flow guide assembly 220, a driving member 230, and a first air guide member 240. The internal gas is driven by the driving member 230 to flow in the air inlet duct 211 and the air outlet duct after being purified by the purification assembly 210, the flow guide assembly 220 forms a first sub-air duct 2211 and a second sub-air duct 2212, and the first air guide member 240 guides the gas in the first air outlet duct 221. After the gas is guided by the first air guide member 240, the internal flow field can be optimized, so that the blown gas is more uniform and soft, thereby improving the purification effect and improving the use experience. In addition, the gas of the embodiment can be flowed out from the first sub-air duct 2211 alone, and can also be flowed out from the first sub-air duct 2211 and the second sub-air duct 2212 at the same time. When the air speed of the gas flowed out from the first sub-air duct 2211 alone is large, the effect of air supply can be achieved. When the gas is flowed out from the first sub-air duct 2211 and the second sub-air duct 2212 together, the air speed of the gas flowed out from the second sub-air duct 2212 is low, the air volume is large, and the purification effect in the regional space is better. Therefore, the air treatment device 100 of the embodiment can select different air ducts to flow the gas according to the mode, and then flow out towards different air outlets, thereby improving the efficiency of air purification.

[0038] As a specific embodiment of the utility model, as shown in the figure, Figure 2 The cross sections of the first sub-air duct 2211 and the second sub-air duct 2212 of the embodiment are annular, and the second sub-air duct 2212 is located outside the first sub-air duct 2211.

The wind blown out from the second sub-air duct 2212 can purify the gas in the regional space. The wind blown out from the first sub-air duct 2211 has a large air speed, and can play the role of air supply.

[0040] Specifically, the first sub-air duct 2211 of the embodiment is in communication with the air outlet structure 300, and the gas flowing into the first sub-air duct 2211 is finally flowed out by the air outlet structure 300. The air outlet structure 300 of the embodiment can rotate relative to the machine body 200, so that the gas flowing from the first sub-air duct 2211 to the air outlet structure 300 can follow the rotation of the air outlet structure 300. When the air outlet direction of the air outlet structure 300 is not vertical, the covered area range of the air outlet is larger, and the purification area is larger.

[0041] As a specific embodiment of the utility model, as shown in the figure, Figures 3-6As shown, the air treatment device 100 of the embodiment can further include a valve assembly 250 arranged at the front side of the first sub-air duct 2211 and the second sub-air duct 2212, and the valve assembly 250 is controlled to be closed or opened to control the gas to flow to the first sub-air duct 2211 or to flow to the first sub-air duct 2211 and the second sub-air duct 2212.

[0042] Specifically, the valve assembly 250 is arranged in the fuselage 200 of the embodiment, and the valve assembly 250 can control the gas to flow to the first sub-air duct 2211 or to flow to the first sub-air duct 2211 and the second sub-air duct 2212, so as to control the gas flow by controlling the valve, and further control the mode of the air treatment device 100.

[0043] Specifically, the valve assembly 250 of the embodiment can include a fixed part 251 and a moving part 252. The fixed part 251 can include two cylindrical side plates 2511 arranged in each other, and a connecting plate 2512 connecting the two side plates 2511, and at least one first through hole 2513 is arranged at the connecting plate 2512. The side plate 2511 inside is arranged in a structure in communication with the first sub-air duct 2211, and the first through hole 2513 of the connecting plate 2512 is in communication with the second sub-air duct 2212. The moving part 252 is arranged at one side of the connecting plate 2512, and at least one second through hole 2521 is arranged on the moving part 252. When the moving part 252 is controlled to move to the second through hole 2521 and the first through hole 2513 at least partially coincide, the valve assembly 250 is opened, and when the moving part 252 is controlled to move to the second through hole 2521 and the first through hole 2513 do not coincide at all, the valve assembly 250 is closed.

[0044] Specifically, the valve assembly 250 of the embodiment can include a fixed part 251 and a moving part 252, and the first through hole 2513 on the fixed part 251 and the second through hole 2521 on the moving part 252 can be coincided or separated by controlling the rotation of the moving part 252, so as to open or close the second sub-air duct 2212.

[0045] As a specific embodiment of the utility model, Figure 5 and Figure 6 As shown, the valve assembly 250 of the embodiment can further include a motor 253 and a gear 254. The gear 254 is connected with the output shaft of the motor 253 to rotate under the driving of the motor 253. The inner side of the moving part 252 is provided with a tooth engaging with the gear 254, so that the moving part 252 rotates under the driving of the motor 253, and further makes the valve assembly 250 open or close.

[0046] Specifically, the motor 253 drives the gear 254 to rotate, the gear 254 is engaged with the teeth on the moving part 252, and then the motor 253 drives the moving part 252 to rotate, thereby opening and closing the valve.

[0047] Specifically, the moving part 252 of the embodiment is arranged above the connecting plate 2512 of the fixed part 251 and is sleeved outside the inner side plate 2511. Since the gear 254 needs to be engaged with the teeth in the moving part 252, a through hole 2514 is arranged at the inner side plate 2511 of the fixed part 251, the gear 254 is located at the side of the through hole 2514, and the teeth of the gear 254 pass through the through hole 2514 and are engaged with the teeth on the moving part 252.

[0048] As a specific embodiment of the utility model, the number of the first through holes 2513 and the second through holes 2521 is multiple, and the first through holes 2513 and the second through holes 2521 that are overlapped with each other have the same structure when the valve assembly 250 is completely opened.

A certain spacing is left between each first through hole 2513, and the spacing is greater than or equal to the width of the first through hole 2513. Similarly, a certain spacing is left between the second through holes 2521, and the spacing is greater than or equal to the width of the second through hole 2521. When the valve assembly 250 is closed, the second through hole 2521 is located at the position between two first through holes 2513, and the first through hole 2513 is also located at the position between two second through holes 2521. At this time, the gas can only flow from the inside of the inner side plate 2511 to the first sub-air duct 2211. When the moving part 252 is driven to move to the position where the first through hole 2513 and the second through hole 2521 are overlapped with each other, the valve assembly 250 is opened. At this time, the gas can not only flow from the inside of the inner side plate 2511 to the first sub-air duct 2211, but also flow from the first through hole 2513 and the second through hole 2521 to the second sub-air duct 2212.

[0050] Specifically, as shown in the drawings, the first air guide part 240 of the embodiment can include a plurality of first air guide blades 241. The plurality of first air guide blades 241 are inclined toward the same direction. The air guide blades of the first air guide part 240 are inclined toward the same direction, which can make the gas in the first air outlet duct 221 rotate and blow out in one direction, thereby optimizing the internal flow field. Figure 7

[0051] ​Specifically, the first air guide 240 of the embodiment is located at one side of the air inlet of the valve assembly 250. In this way, the air flow can pass through the first air guide 240 and then flow to the valve assembly 250, so that the air flow in the first sub-air duct 2211 and the second sub-air duct 2212 can be more uniform.

[0052] As a specific embodiment of the utility model, as shown in Figure 2 and Figure 7 The air treatment device 100 of the embodiment can also include a second air guide 260. The second air guide 260 is arranged in the first sub-air duct 2211 and located at a position of the first sub-air duct 2211 close to the air outlet structure 300, so that the air flow passes through the second air guide 260 and then enters the air outlet structure 300.

[0053] Specifically, the second air guide 260 is arranged at a position of the first sub-air duct 2211 close to the air outlet structure 300, so that the air flow from the first sub-air duct 2211 to the air outlet structure 300 is guided by the second air guide 260, thereby optimizing the flow field of the air in the air outlet structure 300.

[0054] As a specific embodiment of the utility model, the second air guide 260 of the embodiment can include a plurality of second air guide blades 261, and the plurality of second air guide blades 261 are inclined in the same direction.

[0056] Specifically, the inclination direction of the first air guide blade 241 can be the same as or opposite to the inclination direction of the second air guide blade 261. Of course, it is preferred that the inclination direction of the first air guide blade 241 is the same as that of the second air guide blade 261, so that the air flow can rotate in the same direction, avoiding the air flow being turbulent.

[0057] As a specific embodiment of the utility model, as shown in Figure 2 The air outlet structure 300 of the embodiment can include a second air outlet duct 310. The second air outlet duct 310 is in communication with the first sub-air duct 2211, so that the air in the first sub-air duct 2211 flows to the second air outlet duct 310 and then flows out.

[0058] The second air outlet air duct 310 of the embodiment is also an annular air duct, and the air inlet thereof is buckled with the air outlet of the first sub-air duct 2211, so that the air of the first sub-air duct 2211 flows to the second air outlet air duct 310 and then flows out, thereby the angle of air outlet, the sweeping area and the like can be changed through the structure and movement of the air outlet structure 300, and then the angle of air outlet and the sweeping area under different requirements can be met.
