Air outlet device and bladeless fan

Abstract

This invention provides an air outlet device and a bladeless fan, including a fan, a purification component, and a drive mechanism. The fan has an air inlet and an air outlet spaced apart. The purification component is movably coupled to the fan and is used to purify the air. The drive mechanism is drively connected to the purification component and is used to drive the purification component to move relative to the fan, either moving it to the air inlet or moving it away from the air inlet. The purification component in this application can rotate relative to the fan under the drive of the drive mechanism, allowing it to move to the air inlet to purify the air entering the fan, or to move away from the air inlet to ensure smooth air intake for the fan. This allows both the air outlet device and the bladeless fan to simultaneously possess purification and air blowing effects, thereby improving the applicability of the air outlet device and the bladeless fan.

Description

Technical Field

[0001] This invention relates to the field of fans, and in particular to an air outlet device and a bladeless fan. Background Technology

[0002] Currently, bladeless fans on the market utilize two drive methods: mixed-flow blades and centrifugal blades. Mixed-flow bladeless fans offer a large pressure drop, allowing air to pass through high-efficiency filters for strong purification. However, traditional mixed-flow blades have poor work capacity, requiring high-speed motors (above 4000 rpm), resulting in high motor costs. They also have low airflow and velocity regardless of whether there's a filter, leading to relatively poor airflow. Centrifugal bladeless fans, on the other hand, offer strong work capacity, require lower motor speeds (below 2000 rpm), have lower motor costs, and provide a large airflow and velocity even without a filter, resulting in good airflow. However, traditional centrifugal bladeless fans have a small pressure drop, leading to significant airflow reduction and no purification effect when air passes through a high-efficiency filter. Therefore, traditional bladeless fans cannot simultaneously meet the requirements for both effective airflow and air purification. Summary of the Invention

[0003] Therefore, it is necessary to provide an air outlet device and a bladeless fan to address the problem that traditional bladeless fans cannot simultaneously meet the requirements for air blowing effect and purification effect.

[0004] The technical solution is as follows:

[0005] On the one hand, an air outlet device is provided, including:

[0006] The fan has an air inlet and an air outlet spaced apart.

[0007] A purification component, which is movably coupled with the fan, is used to purify the air; and

[0008] A drive mechanism is connected to the purification component for driving the purification component to move relative to the fan, so that the purification component moves to the air inlet or moves away from the air inlet.

[0009] The technical solution will be further explained below:

[0010] In one embodiment, the purification component includes a filter element and a mounting element. The mounting element has a mounting cavity, and the fan is disposed within the mounting cavity. The outer wall of the mounting element has a vent and a filter port communicating with the mounting cavity. The filter element is disposed at the filter port of the mounting element. The driving mechanism is connected to the mounting element and is used to drive the mounting element to rotate the filter element relative to the fan. The filter port and the vent are arranged around the rotation axis of the mounting element.

[0011] In one embodiment, the mounting component includes a mounting ring, a filter grille, and an air inlet grille. The filter grille and the air inlet grille are disposed on the mounting ring in an axial direction around the mounting ring. The filter grille and the air inlet grille together form the mounting cavity. The filter grille has a filter port, and the air inlet grille has a ventilation port. The filter element is mounted on the filter grille, and the driving mechanism is used to drive the mounting ring to rotate.

[0012] In one embodiment, the driving mechanism includes a driving source and a first transmission component, and a second transmission component is provided on the mounting ring. The second transmission component is in transmission cooperation with the first transmission component, and the driving source is used to drive the mounting component to rotate relative to the fan through the first transmission component and the second transmission component.

[0013] In one embodiment, the first transmission component is a gear, the second transmission component is a rack, the rack is disposed on the mounting ring along the circumference of the mounting ring, the gear and the rack cooperate, and the drive source is used to drive the gear to rotate.

[0014] In one embodiment, the air outlet device further includes a mounting shell disposed within the mounting cavity. The fan and the drive source are both disposed within the mounting shell. The outer wall of the mounting shell has an air inlet, an air outlet, and a connecting port spaced apart. The air inlet is connected to the air intake, and the air outlet is connected to the air outlet. The first transmission member passes through the connecting port and is connected to the second transmission member. The mounting member is rotatably engaged with the mounting shell, and the ventilation port and / or the filter on the mounting member can be aligned with the air inlet.

[0015] In one embodiment, an air intake channel is provided inside the mounting housing, with one end of the air intake channel connected to the air inlet and the other end connected to the air intake port. The size of the air intake channel tends to decrease from the air inlet to the air intake port.

[0016] In one embodiment, the air outlet device further includes a mounting base, the mounting housing is disposed on the mounting base, and the mounting component is rotatably disposed on the mounting base.

[0017] In one embodiment, the mounting base has an annular support portion and a receiving groove located within the annular support portion. The mounting ring of the mounting member is disposed within the receiving groove. The outer diameters of the filter grille and the air inlet grille are both larger than the inner diameter of the receiving groove. The filter grille and the air inlet grille are rotatably disposed on the annular support portion. The receiving groove communicates with the mounting cavity through the mounting ring. One side of the mounting shell passes through the mounting ring and connects to the bottom wall of the receiving cavity. The second transmission member is disposed on the inner wall of the mounting ring. The communication port on the mounting shell is correspondingly disposed with the second transmission member.

[0018] In one embodiment, the air outlet device further includes a protective shell, in which a protective cavity is formed. The fan, the purification component, the drive mechanism, and the mounting shell are all disposed in the protective cavity. The outer wall of the protective shell has an air inlet hole and a connecting hole that communicate with the protective cavity. The air inlet hole is connected to the air inlet port, and the connecting hole is connected to the air outlet port.

[0019] In one embodiment, the air outlet device further includes a guide member, one end of which passes through the connecting hole and the air outlet and is disposed at the air outlet of the fan. The guide member is provided with an airflow channel, which is connected to the air outlet.

[0020] On the other hand, a bladeless fan is provided, including the aforementioned air outlet device.

[0021] In the above embodiments, when air purification is required, the drive mechanism is activated, which moves the purification component relative to the fan. Once the purification component reaches the air inlet, the drive mechanism is closed, and the fan is activated. Air is then purified by the purification component at the air inlet and blown out of the air outlet by the fan. This allows both the air outlet and the bladeless fan to purify the air. When airflow is required, the drive mechanism is activated again, moving the purification component relative to the fan. Once the purification component moves away from the air inlet, the drive mechanism is closed again, allowing air to smoothly enter the fan and be blown out of the air outlet. This enables both the air outlet and the bladeless fan to blow air at a high volume and speed. Compared to traditional air outlet devices, the purification component in this application can rotate relative to the fan under the drive of the drive mechanism, so that the purification component can move to the air inlet to purify the air entering the fan, or the purification component can move away from the air inlet to ensure smooth air intake of the fan. Thus, both the air outlet device and the bladeless fan can have both purification and blowing effects at the same time, thereby improving the applicability of the air outlet device and the bladeless fan.

[0047] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] like Figures 1 to 6As shown, in one embodiment, an air outlet device 10 is provided, including a fan 100, a purification component 200, and a drive mechanism 300. The fan 100 has an air inlet 110 and an air outlet 120 spaced apart. The purification component 200 is movably coupled to the fan 100 and is used to purify the air. The drive mechanism 300 is drively connected to the purification component 200 and is used to drive the purification component 200 to move relative to the fan 100, so that the purification component 200 moves to or away from the air inlet 110.

[0049] In the above embodiment, when air purification is required, the drive mechanism 300 is activated, driving the purification component 200 to move relative to the fan 100. After the purification component 200 moves to the air inlet 110, the drive mechanism 300 is closed, and the fan 100 is activated. This allows air to be purified by the purification component 200 at the air inlet 110 and then blown out from the air outlet 120 by the fan 100, thus enabling the air outlet 10 to purify the air. When air blowing is required, the drive mechanism 300 is activated again, driving the purification component 200 to move relative to the fan 100. After the purification component 200 moves away from the air inlet 110, the drive mechanism 300 is closed again, allowing air at the air inlet 110 to smoothly enter the fan 100 and be blown out from the air outlet 120 by the fan 100, thus enabling the air outlet 10 to blow air with a large volume and high speed. Compared to traditional air outlet devices, the purification component 200 in this application can rotate relative to the fan 100 under the drive of the drive mechanism 300, so that the purification component 200 can move to the air inlet 110 to purify the air entering the fan 100, or the purification component 200 can move away from the air inlet 110 to ensure smooth air intake of the fan 100, thereby enabling the air outlet device 10 to have both purification and blowing effects, thus improving the applicability of the air outlet device 10.

[0050] The air outlet device 10 can be applied to the fields of air purification, heat dissipation, or other fields that require air outlet.

[0051] The fan 100 can be a centrifugal fan, a mixed-flow fan, or other types of fan. In this embodiment, the fan 100 is a centrifugal fan.

[0052] The fan 100 has an air inlet 110 and an air outlet 120 spaced apart. The air inlet 110 and air outlet 120 can be spaced apart on two adjacent outer walls of the fan 100; or the air inlet 110 and air outlet 120 can be spaced apart on two opposite outer walls of the fan 100. Figure 6As shown, in this embodiment, the air inlet 110 is located on the outer side wall of the fan 100, and the air outlet 120 is located on the top wall of the fan 100.

[0053] like Figure 5 , Figure 6 and Figure 8 As shown, in one embodiment, the fan 100 includes a volute 130 with an internal receiving cavity 131, a first motor 140, and a fan blade 150. An air inlet 110 is located on the outer wall of the volute 130, and an air outlet 120 is located on the top wall of the volute 130. The first motor 140 is connected to the fan blade 150, which is disposed within the receiving cavity 131. Thus, the first motor 140 can drive the fan blade 150 to rotate within the receiving cavity 131, enabling the first motor 140 to stably and reliably deliver air from the air inlet 110 to the air outlet 120 to form an airflow, thereby improving the reliability and stability of the fan 100.

[0054] like Figure 6 and Figure 20 As shown, optionally, the first motor 140 is provided with a first rotating shaft 141, and a mounting bracket 134 is provided on the outer wall of the volute 130. The first motor 140 is mounted on the mounting bracket 134, and the first rotating shaft 141 at least partially passes through the air inlet 110 and is connected to the fan blade 150 in the receiving cavity 131. This improves the reliability and stability of the fan 100.

[0055] like Figure 5 , Figure 6 , Figure 18 and Figure 19 As shown, the volute 130 further includes a first volute 132 and a second volute 133, which are detachably connected. The first volute 132 and the second volute 133 together form a receiving cavity 131 and an air outlet 120. The air outlet 120 is formed on the top wall at the connection between the first volute 132 and the second volute 133. Air inlets 110 are provided on the outer walls of both the first volute 132 and the second volute 133. A first motor 140 is installed on one of the outer walls of the first volute 132 and the second volute 133. This improves the ease of assembly of the fan 100.

[0056] The first volute 132 and the second volute 133 are detachably connected by at least one of the following methods: snap-fit, plug-in, screw-in, or other detachable connection methods.

[0057] The drive mechanism 300 is used to drive the purification component 200 to move relative to the fan 100. The drive mechanism 300 can drive the purification component 200 to rotate, slide or move in other ways relative to the fan 100.

[0058] like Figure 5 , Figure 6 and Figure 14 As shown, the purification component 200 further includes a filter element 210 and a mounting component 220. A mounting cavity 221 is formed in the mounting component 220. The fan 100 is disposed in the mounting cavity 221. A vent 222 and a filter port 223 communicating with the mounting cavity 221 are formed on the outer wall of the mounting component 220. The filter element 210 is disposed at the filter port 223 of the mounting component 220. A drive mechanism 300 is connected to the mounting component 220 for transmission. The drive mechanism 300 is used to drive the mounting component 220 to drive the filter element 210 to rotate relative to the fan 100. The filter port 223 and the vent 222 are arranged around the rotation axis F of the mounting component 220. Thus, when air purification is required, the drive mechanism 300 drives the mounting component 220 to rotate the filter element 210, causing the filter element 210 to rotate to the air inlet 110, and the filter port 223 to connect with the air inlet 110. Air then passes sequentially through the filter element 210, the filter port 223, and the air inlet 110 before entering the fan 100, ensuring that the filter element 210 can filter and purify the air entering the fan 100, thereby achieving the air purification effect of the air outlet device 10. When blowing air is required, the drive mechanism 300 drives the mounting component 220 to rotate the filter element 210, causing the filter element 210 to rotate away from the air inlet 110, and the vent 222 to rotate to a position connected to the air inlet 110. This allows air to flow smoothly from the vent 222 and the air inlet 110 into the fan 100, ensuring that the fan 100 has a large air volume, thereby achieving the blowing effect of the air outlet device 10.

[0059] The filter element 210 can be a filter screen, a high-efficiency filter screen, a filter membrane, or other filtration structure. The mounting element 220 can be a mounting bracket, a mounting base, or other mounting structure.

[0060] like Figure 8 and Figure 14 As shown, in this embodiment, the mounting member 220 has a cylindrical structure, and the filter port 223 and the vent 222 are arranged around the central axis F of the mounting member 220, that is, the central axis F of the mounting member 220 is also the rotation axis F of the mounting member 220. In other embodiments, the mounting member may also be a frustum-shaped structure or an annular structure, etc. Figure 5 and Figure 6As shown, optionally, the mounting component 220 includes a mounting ring 224, a filter grille 225, and an air inlet grille 226. The filter grille 225 and the air inlet grille 226 are disposed on the mounting ring 224 in the axial direction around the mounting ring 224. The filter grille 225 and the air inlet grille 226 together form a mounting cavity 221. A filter port 223 is formed on the filter grille 225, and a vent 222 is formed on the air inlet grille 226. The filter element 210 is mounted on the filter grille 225. The drive mechanism 300 is used to drive the mounting ring 224 to rotate. Thus, when the air outlet device 10 needs to purify the air, the drive mechanism 300 drives the mounting ring 224 to rotate, causing the mounting ring 224 to rotate the filter grille 225 and the filter element 210 to the air inlet 110. Furthermore, there is no interference between the filter element 210 and the fan 100, improving the reliability and stability of the air purification by the air outlet device 10. In addition, when the air outlet device 10 needs to blow air, the drive mechanism 300 drives the mounting ring 224 to rotate, so that the mounting ring 224 drives the air inlet grille 226 to rotate to the air inlet 110, thereby enabling the air inlet grille 226 to block larger objects in the air from entering the fan 100 through the air inlet 110, thus improving the safety of the air outlet device 10.

[0061] The axial direction of the mounting ring 224 is also the rotation axis F of the mounting component 220. Figure 5 As shown in the F direction. The filter grille 225 and the air inlet grille 226 are arranged on the mounting ring 224 around the axis of the mounting ring 224, that is, the filter grille 225 and the air inlet grille 226 are arranged on the mounting ring 224 around the F direction. In this embodiment, the filter grille and the air inlet grille form a cylindrical structure.

[0062] like Figure 5 , Figure 8 , Figure 13 and Figure 14 As shown, in one embodiment, the drive mechanism 300 includes a drive source 310 and a first transmission member 320. A second transmission member 227 is provided on the mounting ring 224, and the second transmission member 227 is in transmission cooperation with the first transmission member 320. The drive source 310 is used to drive the mounting member 220 to rotate relative to the fan 100 through the first transmission member 320 and the second transmission member 227. In this way, the mounting ring 224 can drive the filter member 210 to rotate relative to the fan 100 through the filter grille 225, thereby improving the reliability and stability of the air outlet device 10.

[0063] The drive source 310 can be a motor, a rotary hydraulic cylinder, a rotary pneumatic cylinder, or other drive components. The first transmission component 320 can be a gear transmission mechanism, a belt transmission mechanism, or other transmission structure. The second transmission component 227 can correspond to a transmission wheel, transmission teeth, or other transmission structure.

[0064] like Figure 10 and Figure 14 As shown, the first transmission component 320 is a gear, and the second transmission component 227 is a rack. The rack is arranged circumferentially on the mounting ring 224, and the gear and rack cooperate. The drive source 310 is used to drive the gear to rotate. In this way, the drive source 310 can drive the filter element 210 to rotate relative to the fan 100 through the gear, rack, mounting ring 224, and filter grille 225, so that the filter element 210 can rotate to the air inlet 110 or rotate away from the air inlet 110, improving the reliability and stability of the air outlet device 10. In addition, the rack is arranged on the mounting ring 224 and works in cooperation with the gear to drive the mounting ring 224 to rotate, which increases the stability and reliability of the rotation of the filter element 210 relative to the fan 100 through the filter grille 225, thus improving the reliability and stability of the fan 10.

[0065] like Figure 12 , Figure 15 and Figure 16 As shown, in one embodiment, the air outlet device 10 further includes a mounting housing 400, which is disposed within the mounting cavity 221. The fan 100 and the drive source 310 are both disposed within the mounting housing 400. The outer wall of the mounting housing 400 has spaced-apart air inlets 410, air outlets 420, and connecting ports 430. The air inlet 410 is connected to the air inlet 110, and the air outlet 420 is connected to the air outlet 120. A first transmission member 320 passes through the connecting port 430 and is connected to a second transmission member 227. The mounting member 220 is rotatably engaged with the mounting housing 400, and the ventilation openings 222 or filters 210 on the mounting member 220 can be aligned with the air inlet 410. Thus, the mounting housing 400 can protect the fan 100 and the drive source 310, improving the safety and service life of the air outlet device 10. In addition, after the fan 100 and the drive source 310 are installed in the mounting housing 400, the mounting housing 400 and the mounting component 220 are then assembled accordingly, so that the first transmission component 320 and the second transmission component 227 are connected in transmission, which improves the convenience and efficiency of assembling the air outlet device 10.

[0066] The fan 100 and the drive source 310 are both housed within the mounting housing 400 and can be connected by snap-fit, plug-in, screw-in or other means.

[0067] like Figure 12 , Figure 13 and Figure 15As shown, further, an air inlet channel 440 is provided inside the mounting housing 400. One end of the air inlet channel 440 is connected to the air inlet 410, and the other end is connected to the air inlet 110. From the air inlet 410 to the air inlet 110, the size of the air inlet channel 440 tends to decrease. In this way, from the air inlet 410 to the air inlet 110, the air velocity in the air inlet channel 440 gradually increases, which increases the air velocity at both the air inlet 110 and the air outlet 120, thereby improving the blowing effect of the air outlet device 10.

[0068] Specifically, the air inlet channel 440 is located within the mounting cavity 221 of the mounting component 220, with the other end of the air inlet channel 440 connected to the air inlet 110. When purification is required, the mounting component 220 rotates so that one end of the air inlet channel 440 is connected to the filter port 223, which is in communication with the air inlet 410. The air filtered through the filter port 223 can then enter the air inlet channel 440 and effectively enter the air inlet 110. When purification is not required, the mounting component 220 rotates so that one end of the air inlet channel 440 is connected to the vent 222, which is in communication with the air inlet 410. The air in the vent 222 can then effectively enter the air inlet 110 through the air inlet channel 440. The air inlet channel 440 allows the fresh air from the purification component 200 to enter the air inlet 110 of the fan 110 more stably.

[0069] Since the outer wall of the fan 100 is non-cylindrical, while the mounting cavity 221 formed within the mounting component 220 is cylindrical, an air inlet channel 440 is provided within the mounting cavity 221 to ensure stable and reliable communication between the air inlet 110 on the fan 100 and the filter port 223 or vent 222 on the mounting component 220. One end of the air inlet channel 440 is connected to the air inlet 110, and the contour shape of the other end of the air inlet channel 440 is adapted to the contour shape of both the filter port 223 and the vent 222 on the mounting component 220. This allows the air inlet channel 440 to act as a transitional connection, ensuring that the air inlet 110 is connected to the filter port 223 or the vent 222, thereby improving the stability and reliability of the air outlet device 10.

[0070] like Figure 13 and Figure 15As shown, optionally, a baffle 450 is also provided inside the mounting housing 400. The baffle 450 is provided at one end of the air inlet channel 440 near the air inlet 110, and the baffle 450 is provided with a vent hole 451. In this way, the cross-sectional area for airflow between the air inlet channel 440 and the air inlet 110 is further reduced, which further increases the airflow velocity at the air inlet 110 and improves the air outlet effect of the air outlet device 10. In addition, when the air outlet device 10 blows air, the baffle 450 can play a secondary filtration role, improving the safety of the air outlet device 10.

[0071] The blocking part 450 can be a blocking plate, a blocking mesh, or other blocking structure. The number of vents 451 can be flexibly adjusted according to actual usage needs.

[0072] like Figure 6 , Figure 10 , Figure 15 and Figure 17 As shown, optionally, a mounting bracket 460 is formed within the mounting housing 400. The mounting bracket 460 has a sliding groove 461, one end of which extends to one side of the mounting bracket 460. The drive source 310 is a second motor 313 equipped with a motor shaft seat 312 and a second rotating shaft 311. The motor shaft seat 312 is slidably connected to the sliding groove 461 and is used to mount the second rotating shaft 311. The second rotating shaft 311 is connected to the first transmission member 320. In this way, the second motor 313 can be precisely installed in a preset position in the mounting housing 400 through the mounting bracket 460, ensuring that the second motor 313 can be connected to the second transmission member 227 through the second rotating shaft 311 and the first transmission member 320, thereby improving the reliability and stability of the air outlet device 10.

[0073] like Figure 5 , Figure 18 and Figure 19 As shown, in one embodiment, the fan 100 is a centrifugal fan 100, which has two spaced-apart air inlets 110. The outer wall of the mounting housing 400 has two air inlets 410, which are spaced apart around the rotation axis of the mounting member 220. One air inlet 110 is connected to the other air inlet 410. There are two filter ports 223 and two filter elements 210. The two filter ports 223 are spaced apart on the mounting member 220 around its rotation axis, and each filter port 223 has a corresponding filter element 210. A vent 222 is formed between the two filter ports 223, and the two filter elements 210 can simultaneously cover both air inlets 410. Thus, the air outlet device 10 can intake air through the two air inlets 110, increasing the airflow of the fan 100 and improving its air outlet speed and purification rate.

[0074] like Figure 12 and Figure 21 As shown, in one embodiment, the air outlet device 10 further includes a mounting base 500, a mounting shell 400 disposed on the mounting base 500, and a mounting member 220 rotatably disposed on the mounting base 500. Thus, the drive mechanism 300 can stably and reliably drive the mounting member 220 to rotate the filter element 210 relative to the mounting shell 400, improving the reliability and stability of the air outlet device 10.

[0075] The mounting housing 400 is mounted on the mounting base 500 and can be connected by snap-fit, screw-fit, plug-in, or other means. The mounting component 220 is rotatably mounted on the mounting base 500 and can be connected by bearings, shafts, bushings, or other rotatable means.

[0076] like Figure 12 and Figure 21 As shown, the mounting base 500 further includes an annular support portion 510 and a receiving groove 520 located within the annular support portion 510. The mounting ring 224 of the mounting member 220 is disposed within the receiving groove 520. The outer diameters of the filter grille 225 and the air inlet grille 226 are both larger than the inner diameter of the receiving groove 520. The filter grille 225 and the air inlet grille 226 are rotatably mounted on the annular support portion 510. The receiving groove 520 communicates with the mounting cavity 221 through the mounting ring 224. One side of the mounting shell 400 passes through the mounting ring 224 and connects to the bottom wall of the receiving groove 520. The second transmission member 227 is disposed on the inner wall of the mounting ring 224, and the communication port 430 on the mounting shell 400 is correspondingly disposed with the second transmission member 227. In this way, the positions of the mounting ring 224 and the mounting shell 400 relative to the mounting base 500 are kept stable, enabling stable and reliable transmission between the first transmission member 320 and the second transmission member 227, thereby improving the reliability and stability of the air outlet device 10. In addition, the annular support 510 supports the rotation of the filter grille 225 and the air inlet grille 226, so that the rotation space of the filter grille 225 and the air inlet grille 226 relative to the mounting housing 400 remains stable, thereby improving the reliability and stability of the air outlet device 10.

[0077] like Figure 12 and Figure 21 As shown, the mounting ring 224 is spaced apart from the inner wall of the receiving groove 520. This reduces the friction between the mounting ring 224 and the mounting base 500, allowing the drive source 310 to smoothly drive the mounting ring 224 to rotate via the first transmission member 320 and the second transmission member 227.

[0078] Specifically, the mounting ring 224 is spaced apart from the inner wall of the receiving groove 520 by the outer diameter of the mounting ring 224 being smaller than the inner diameter of the receiving groove 520, so that the outer wall of the mounting ring 224 is spaced apart from the inner wall of the mounting groove 520.

[0079] like Figure 5, Figure 6 and Figure 8 As shown, in one embodiment, the air outlet device 10 further includes a protective shell 600, within which a protective cavity 610 is formed. The fan 100, purification component 200, drive mechanism 300, and mounting shell 400 are all disposed within the protective cavity 610. The outer wall of the protective shell 600 has an air inlet hole and a connecting hole 670 communicating with the protective cavity 610. The air inlet hole communicates with the air inlet 410, and the connecting hole 670 communicates with the air outlet 420. Thus, the protective shell 600 can protect the fan 100, purification component 200, drive mechanism 300, and mounting shell 400, improving the safety and reliability of the air outlet device 10.

[0080] like Figure 5 , Figure 6 and Figure 8 As shown, the protective shell 600 further includes a front shell 620, a rear shell 630, a left shell 640, a right shell 650, and a cover 660. The cover 660 is spaced apart from the mounting base 500. The front shell 620, rear shell 630, left shell 640, and right shell 650 are all located between the cover 660 and the mounting base 500. The front shell 620, rear shell 630, left shell 640, right shell 650, cover 660, and mounting base 500 together form a protective cavity 610. The outer walls of the left shell 640 and the right shell 650 are provided with air inlets communicating with the protective cavity 610. The outer wall of the mounting shell 400 is provided with two spaced air inlets 410, one air inlet and one air inlet 410 communicating with each other. The outer wall of the cover 660 is provided with a connecting hole 670 communicating with the protective cavity 610, and the connecting hole 670 is connected with the air outlet 420. This improves the ease of machining the air inlet and connecting hole 670.

[0081] The front shell 620, rear shell 630, left shell 640, right shell 650, cover 660 and mounting base 500 together form a protective cavity 610, which can be connected by screws, snaps, plugs or other means.

[0082] like Figure 8 and Figure 21 As shown, optionally, the mounting base 500 also includes an annular mounting portion 530 and a mounting groove 540 located within the annular mounting portion 530. An annular support portion 510 is disposed within the mounting groove 540. The outer side wall of the annular support portion 510 is spaced apart from the inner side wall of the annular mounting portion 530, and the annular mounting portion 530 and the annular support portion 510 are coaxially arranged. A protective cover 600 is disposed on the annular mounting portion 530, so that the protective cover 600 is spaced apart from the purification component 200. In this way, the purification component 200 will not interfere with the protective cover 600 during rotation, improving the reliability and stability of the air outlet device 10.

[0083] like Figures 1 to 5 As shown, the air outlet device 10 further includes a guide member 700. One end of the guide member 700 passes through the connecting hole 670 and the air outlet 420 and is disposed at the air outlet 120 of the fan 100. The guide member 700 is provided with an airflow channel 710, which is connected to the air outlet 120. In this way, the guide member 700 can guide the airflow from the air outlet 120, so that the airflow from the air outlet 120 can be blown out from a preset position and at a preset angle, thereby improving the applicability and safety of the air outlet device 10.

[0084] Among them, the guide component 700 can be an air duct, an annular air guide component, an air outlet grille, or other guide structure.

[0085] In one embodiment, a bladeless fan is provided, including the air outlet device 10 of any of the above embodiments.

[0086] In the bladeless fan described in the above embodiment, when air purification is required, the drive mechanism 300 is activated. The drive mechanism 300 drives the purification component 200 to move relative to the fan 100. After the purification component 200 moves to the air inlet 110, the drive mechanism 300 is closed, and the fan 100 is activated. Air is then purified by the purification component 200 at the air inlet 110 and blown out from the air outlet 120 by the fan 100, thus enabling the bladeless fan to purify the air. When airflow is required, the drive mechanism 300 is activated again, driving the purification component 200 to move relative to the fan 100. After the purification component 200 moves away from the air inlet 110, the drive mechanism 300 is closed again, allowing air at the air inlet 110 to smoothly enter the fan 100 and be blown out from the air outlet 120 by the fan 100, enabling the bladeless fan to blow air with a large air volume and high wind speed. Compared to traditional bladeless fans, the purification component 200 in this application can rotate relative to the fan 100 under the drive of the drive mechanism 300, so that the purification component 200 can move to the air inlet 110 to purify the air entering the fan 100, or the purification component 200 can move away from the air inlet 110 to ensure smooth air intake of the fan 100. This allows the bladeless fan to have both purification and blowing effects, thereby improving the applicability of the bladeless fan.
