[0047] The following is for reference. Figures 1-12 Description of an air supply assembly 100 according to an embodiment of the present utility model.

[0048] like Figures 1-12As shown, the air supply assembly 100 according to an embodiment of the present utility model includes: a bracket 10, an air guide shell 20, a first driving member 40, a fan wheel 30, and a second driving member 50. The bracket 10 may have an air supply area, which may have a first air supply section 11 and a second air supply section 12. The air guide shell 20 may be disposed inside the bracket 10. The air guide shell 20 may be movable relative to the bracket 10, and the air guide shell 20 may have a fan wheel cavity 213. The fan wheel cavity 213 may be selectively connected to the first air supply section 11 or the second air supply section 12 during the movement of the air guide shell 20.

[0049] The first driving member 40 can be mounted on the bracket 10 and connected to the air guide shell 20, allowing the first driving member 40 to drive the air guide shell 20 to move relative to the bracket 10. The impeller 30 can be mounted inside the impeller cavity 213 and can rotate relative to the impeller cavity 213. The second driving member 50 can be mounted on the air guide shell 20 and connected to the impeller 30, allowing the second driving member 50 to drive the impeller 30 to rotate relative to the air guide shell 20. This allows the impeller cavity 213 to selectively pass through the first air delivery section 11 or the second air delivery section 12 in different directions (e.g., ...). Figure 5 (as shown in the front-back or up-down direction) outwards (e.g.) Figure 5 Airflow is supplied in the direction shown (from back to front or from bottom to top).

[0050] The air guide shell 20 can move between a first position and a second position. When the air guide shell 20 is in the first position, the outlet 2132 of the impeller cavity 213 can communicate with the first air supply section 11, and the air guide shell 20 can close the second air supply section 12, so that the impeller cavity 213 can be directed outward through the first air supply section 11 (e.g., Figure 5 Airflow is directed from back to front (as shown).

[0051] When the air guide shell 20 is in the second position, the outlet 2132 of the impeller cavity 213 can communicate with the second air supply section 12, and the air guide shell 20 can close the first air supply section 11, so that the impeller cavity 213 can be directed outward through the second air supply section 12 (e.g., Figure 5 The air supply (shown as a bottom-up direction) ensures the air volume delivered by the impeller cavity 213 through the air supply area, while also enabling the switching of the air direction delivered by the impeller cavity 213. Furthermore, it facilitates the impeller cavity 213 to directly blow air onto the human body through the air supply area, thereby improving the user experience.

[0052] According to the embodiment of the present invention, the air supply assembly 100 is provided with a first air supply section 11 and a second air supply section 12, and the outlet 2132 of the impeller cavity 213 can be selectively connected to the first air supply section 11 and the second air supply section 12. This allows the impeller cavity 213 to supply air outward in different directions through the first air supply section 11 or the second air supply section 12, ensuring the air volume supplied by the air supply assembly 100. At the same time, the air direction supplied by the air supply assembly 100 can be switched, which is beneficial to realizing the direct air blowing function to the human body and improving the user experience. Compared with the technical solution of using a single air duct and setting a rotatable baffle at the end of the air duct to switch the air direction, it can reduce the damage to the air duct, ensure the integrity of the air duct, increase the air volume supplied by the air supply assembly 100, and improve the performance and stability of the air supply assembly 100.

[0053] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, according to some embodiments of the present invention, the air guide shell 20 is rotatably mounted on the bracket 10, and the first air supply part 11 and the second air supply part 12 can be arranged in the rotation direction of the air guide shell 20, so that the outlet 2132 of the impeller cavity 213 can be selectively connected to the first air supply part 11 or the second air supply part 12 during the rotation of the air guide shell 20. This allows the impeller cavity 213 to send air outward in different directions through the first air supply part 11 or the second air supply part 12, which can ensure the air volume sent outward by the air supply component 100, and at the same time, the air direction sent outward by the air supply component 100 can be switched, which is beneficial to realize the direct air blowing function to the human body and can improve the user experience.

[0054] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the air guide shell 20 may include a volute 21 and a sealing shell 22. The volute 21 may define a fan chamber 213. The sealing shell 22 may cooperate with the volute 21, so that the sealing shell 22 and the volute 21 can rotate together relative to the support 10. The sealing shell 22 may close the first air supply section 11 or the second air supply section 12. Thus, when the air guide shell 20 is in the first position, the outlet 2132 of the fan chamber 213 of the volute 21 may communicate with the first air supply section 11, and the sealing shell 22 may close the second air supply section 12. When the air guide shell 20 is in the second position, the outlet 2132 of the fan chamber 213 of the volute 21 may communicate with the second air supply section 12, and the sealing shell 22 may close the first air supply section 11.

[0055] At least a portion of the sealing shell 22 can be disposed between the volute 21 and the support 10, that is, the sealing shell 22 can fill the gap between the volute 21 and the support 10. When the air guide shell 20 is in the first position, the sealing shell 22 can fill the gap between the volute 21 and the support 10 at the position of the second air supply section 12, which can improve the sealing performance of the sealing shell 22 on the second air supply section 12 when the second air supply section 12 is closed, and can prevent the outlet 2132 of the impeller cavity 213 and the second air supply section 12 from connecting when the air guide shell 20 is in the first position.

[0056] Furthermore, when the air guide shell 20 is in the second position, the sealing shell 22 can fill the gap between the volute 21 and the bracket 10 at the position of the first air supply section 11, which can improve the sealing performance of the sealing shell 22 on the first air supply section 11 when it is closed, and prevent the outlet 2132 of the impeller cavity 213 and the first air supply section 11 from connecting when the air guide shell 20 is in the second position, thereby preventing air from entering the impeller cavity 213 through the closed air supply section.

[0057] The sealing shell 22 may have an opening 223, and the opening 223 and the outlet 2132 of the impeller cavity 213 may be positioned correspondingly, which can avoid the outlet 2132 of the impeller cavity 213, so that the outlet 2132 of the impeller cavity 213 and the first air supply section 11 can be normally connected when the air guide shell 20 is in the first position, and the outlet 2132 of the impeller cavity 213 and the second air supply section 12 can be normally connected when the air guide shell 20 is in the second position, thereby increasing the air supply volume of the air supply assembly 100 and improving the performance and stability of the air supply assembly 100.

[0058] like Figure 1 and Figure 3 As shown, in some embodiments, the sealing shell 22 may include a first baffle 221 and a second baffle 222 arranged at intervals, and an opening 223 may be located between the first baffle 221 and the second baffle 222. When the air guide shell 20 is in the first position, the first baffle 221 may be rotated between the bracket 10 and the volute 21 to open the first air supply section 11, that is, the outlet 2132 of the impeller cavity 213 may be normally connected to the first air supply section 11 through the opening 223, and the second baffle 222 may be rotated to the position of closing the second air supply section 12 to close the second air supply section 12, and may fill the gap between the volute 21 and the bracket 10 at the position of the second air supply section 12, thereby achieving a seal on the second air supply section 12.

[0059] When the air guide housing 20 is in the second position, the first baffle 221 can be rotated to the position of closing the first air supply section 11 to close the first air supply section 11, and can fill the gap between the volute housing 21 and the bracket 10 at the position of the first air supply section 11, thereby achieving a seal on the first air supply section 11. The second baffle 222 can be rotated between the bracket 10 and the volute housing 21 to open the second air supply section 12, that is, the outlet 2132 of the impeller cavity 213 can be normally connected to the second air supply section 12 through the opening 223, thereby ensuring the air volume of the air supply assembly 100 to the outside, improving the performance and stability of the air supply assembly 100, and at the same time, the air direction of the air supply assembly 100 to the outside can be switched, which can improve the user experience.

[0060] like Figure 1 and Figure 3 As shown, in some embodiments, the volute 21 may include a volute body 211 and a volute tongue 212, and the volute body 211 may have a first side disposed opposite to each other (e.g., Figure 1 (as shown in the front side) and the second side (as shown in the second side) Figure 1 As shown on the rear side), the volute tongue 212 can be connected to the first side of the volute body 211, and the volute tongue 212 can be arranged opposite to the second side of the volute body 211. That is, the volute tongue 212 can be located at the first side edge of the outlet 2132 of the impeller cavity 213, which can prevent gas from circulating in the volute 21, ensure the air volume of the air supply assembly 100 to the outside, and improve the performance and stability of the air supply assembly 100.

[0061] The first baffle 221 can be disposed on the outside of the volute body 211, and the first baffle 221 can abut against the volute tongue 212, that is, the first baffle 221 can be located on the first side of the outlet 2132 of the impeller cavity 213. At least a portion of the second baffle 222 can be disposed on the outside of the volute body 211, and the second baffle 222 can abut against the second side of the volute body 211, that is, the second baffle 222 can be located on the second side of the outlet 2132 of the impeller cavity 213. This can prevent the first baffle 221 and the second baffle 222 from interfering with each other. At the same time, it can ensure that the second baffle 222 rotates to the position of closing the second air supply section 12 when the air guide shell 20 is in the first position, and it can ensure that the first baffle 221 rotates to the position of closing the first air supply section 11 when the air guide shell 20 is in the second position.

[0062] At least a portion of the first baffle 221 and the second baffle 222 can be arc-shaped plates. The two arc-shaped plates can be located on the cylindrical surface of the same cylinder, and the central axis of the cylinder coincides with the rotation axis of the air guide shell 20. On the one hand, this can prevent the first baffle 221 and the second baffle 222 from interfering with the bracket 10 when the air guide shell 20 rotates, thus ensuring the normal rotation of the air guide shell 20. On the other hand, it can increase the projected area of ​​the first baffle 221 along the radial direction of the air guide shell 20, thereby improving the sealing effect on the first air supply part 11, and it can also increase the projected area of ​​the second baffle 222 along the radial direction of the air guide shell 20, thereby improving the sealing effect on the second air supply part 12.

[0063] In some embodiments, the sealing shell 22 may further include a first end plate (not shown) and a second end plate (not shown), the first end plate and the second end plate being located in the extension direction of the rotation axis of the air guide shell 20 (e.g., Figure 2 The sealing shell 22 and the volute 21 are arranged opposite each other in the left and right directions, which is conducive to the connection between the sealing shell 22 and the volute 21, and to the rotation of the sealing shell 22 and the volute 21 together relative to the bracket 10. The first baffle 221 and the second baffle 222 can both be connected between the first end plate and the second end plate, so that the first baffle 221 and the second baffle 222 can rotate together relative to the bracket 10 to close the first air supply section 11 and the second air supply section 12 respectively.

[0064] For example, when the air guide shell 20 is in the first position, the first baffle 221 can rotate between the bracket 10 and the volute 21 to open the first air supply section 11, and the second baffle 222 can rotate to the position of closing the second air supply section 12 to close the second air supply section 12. When the air guide shell 20 is in the second position, the first baffle 221 can rotate to the position of closing the first air supply section 11 to close the first air supply section 11, and the second baffle 222 can rotate between the bracket 10 and the volute 21 to open the second air supply section 12.

[0065] The first end plate can be connected to the first driving member 40, and the second end plate can be rotatably connected to the bracket 10, so that the first driving member 40 can drive the sealing shell 22 and the volute 21 to rotate together, that is, the first driving member 40 can drive the air guide shell 20 to rotate relative to the bracket 10 between the first position and the second position. Alternatively, the second end plate can be connected to the first driving member 40, and the first end plate can be rotatably connected to the bracket 10.

[0066] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the wind turbine 30 may include: a disk 33, a plurality of first blades 31, and a plurality of second blades 32, wherein the plurality of first blades 31 may be disposed on one side of the disk 33 (e.g., Figure 2As shown on the left), and multiple first blades 31 can be arranged circumferentially on the wheel 33, and multiple second blades 32 can be disposed on the other side of the wheel 33 (e.g., on the left). Figure 2 (as shown on the right), and multiple second blades 32 can be arranged circumferentially on the impeller 33, that is, the inlet 2131 of the impeller cavity 213 can be located in the axial direction of the volute 21 (as shown on the right). Figure 2 The opposite sides (as shown in the left and right directions) on the left and right sides (e.g.) Figure 2 (As shown on the left and right sides), it can realize double-sided air intake of the impeller cavity 213, which can increase the air volume of the air supply component 100 to the outside, and can improve the performance and stability of the air supply component 100.

[0067] The second driving component 50 can be disposed inside the volute 21, and at least a portion of the second driving component 50 can be located within the space enclosed by multiple first blades 31 or multiple second blades 32. Based on the normal driving of the impeller 30 by the second driving component 50, the internal space of the impeller 30 can be fully utilized, and the space occupied by the second driving component 50 in the air guide shell 20 can be reduced, which is beneficial to the miniaturization of the air supply assembly 100.

[0068] like Figure 1 and Figure 3 As shown, according to some embodiments of the present invention, the bracket 10 may have a separator 13, which may be located between the first air supply section 11 and the second air supply section 12. This separator can separate the first air supply section 11 and the second air supply section 12, allowing the impeller cavity 213 to supply air outward through the first air supply section 11 when the air guide shell 20 is in the first position, and allowing the impeller cavity 213 to supply air outward through the second air supply section 12 when the air guide shell 20 is in the second position. This ensures the air volume supplied by the impeller cavity 213 through the air supply area, and also allows for switching of the air direction supplied by the impeller cavity 213. Furthermore, it facilitates the impeller cavity 213 directly blowing air onto the human body through the air supply area, thereby improving the user experience.

[0069] like Figure 1 and Figure 3 As shown, in some embodiments, the separator 13 may have a first limiting part 131, the bracket 10 may also have a second limiting part 14, the second air supply part 12 may be located between the first limiting part 131 and the second limiting part 14, the air guide shell 20 may have a mating part 224, the mating part 224 may be disposed on the second baffle 222, or the mating part 224 may be a part of the second baffle 222, wherein the mating part 224 may be limited between the first limiting part 131 and the second limiting part 14, so that the air guide shell 20 may rotate between the first position and the second position, thereby realizing the switching of the outward air supply direction of the air supply assembly 100 and improving the reliability of the switching of the outward air supply direction of the air supply assembly 100.

[0070] When the air guide shell 20 is in the first position, the first limiting part 131 can cooperate with the mating part 224 to stop and limit the air guide shell 20, and prevent the air guide shell 20 from rotating excessively relative to the bracket 10. At this time, the second baffle 222 can close the second air supply part 12, and the first baffle 221 can open the first air supply part 11 so that the outlet 2132 of the impeller cavity 213 and the first air supply part 11 are connected.

[0071] When the air guide shell 20 is in the second position, the second limiting part 14 can cooperate with the mating part 224 to stop and limit the air guide shell 20, and prevent the air guide shell 20 from rotating excessively relative to the bracket 10. At this time, the second baffle 222 can open the second air supply part 12 so that the outlet 2132 of the impeller cavity 213 and the second air supply part 12 are connected, and the first baffle 221 can close the first air supply part 11, thereby realizing the switching of the air supply direction of the air supply assembly 100 to the outside, and improving the reliability of the air supply direction switching of the air supply assembly 100 to the outside.

[0072] like Figure 1 and Figure 3 As shown, in some embodiments, the first limiting portion 131 may include a limiting rib, and the mating portion 224 faces the side of the impeller cavity 213 (e.g., Figure 1 The lower side shown may have a first mating surface, and the mating part 224 has a second mating surface on the side away from the impeller cavity 204. The second limiting part 14 includes a limiting surface 141. The bracket 10 also has a sealing surface 142 on the side facing the impeller cavity 204. The sealing surface 142 is connected to the limiting surface 141 and is set at an angle. The sealing surface 142 is closer to the rotation axis of the air guide shell 20 than the limiting surface 141. When the air guide shell 20 is in the first position, the limiting rib and the first mating surface can be set at an angle, and the limiting rib can stop the first mating surface, which can limit the air guide shell 20 and prevent the air guide shell 20 from rotating excessively relative to the bracket 10. The sealing surface 142 contacts and engages with the second mating surface, which can seal the second air supply part 12 and prevent air from entering the volute 21.

[0073] It is understandable that a first imaginary circle is defined in a plane perpendicular to the rotation axis of the air guide shell 20. The center of the first imaginary circle can be the rotation center of the air guide shell 20, and the first imaginary circle can pass through the fixed end of the projection of the first mating surface on the aforementioned plane. The limiting rib can extend along the rotation direction of the air guide shell 20, or the limiting rib can extend along the tangent of the first imaginary circle. The projection of the first mating surface on the aforementioned plane can be deflected outward relative to the tangent of the first imaginary circle at the fixed end, thereby ensuring that the limiting rib and the first mating surface are in full contact, improving the stopping effect between the limiting rib and the first mating surface, and improving the limiting effect on the air guide shell 20.

[0074] like Figure 1 and Figure 3 As shown, in some embodiments, the second limiting portion 14 may include a limiting surface 141, on the side of the mating portion 224 facing away from the impeller cavity 213 (e.g. Figure 1 The upper side shown may have a second mating surface. When the air guide shell 20 is in the second position, the limiting surface 141 can contact the second mating surface, and the limiting surface 141 can stop the second mating surface, thereby limiting the air guide shell 20 and preventing the air guide shell 20 from rotating excessively relative to the bracket 10.

[0075] It is understood that a second imaginary circle is defined in a plane perpendicular to the rotation axis of the air guide shell 20. The center of the second imaginary circle can be the rotation center of the air guide shell 20, and the second imaginary circle can pass through the fixed end of the projection of the second mating surface onto the aforementioned plane. The projection of the limiting surface 141 onto the aforementioned plane can be deflected outward relative to the tangent of the second imaginary circle at the fixed end, and the projection of the second mating surface onto the aforementioned plane can be deflected outward relative to the tangent of the second imaginary circle at the fixed end. The deflection angles of the limiting surface 141 and the second mating surface can be the same, thereby ensuring that the limiting surface 141 and the second mating surface are in full contact, improving the stopping effect between the limiting surface 141 and the second mating surface, and improving the limiting effect on the air guide shell 20.

[0076] like Figure 1 and Figure 3 As shown, in some embodiments, the air guide shell 20 may include a volute 21, which may have a volute tongue 212 to prevent gas from circulating inside the volute 21, to ensure the air volume delivered by the air supply assembly 100, and to improve the performance and stability of the air supply assembly 100. At least a portion of the mating part 224 may be located at the edge of the outlet 2132 of the impeller cavity 213, and the mating part 224 may be disposed opposite to the volute tongue 212.

[0077] Therefore, it can be ensured that the outlet 2132 of the impeller cavity 213 corresponds to and is connected to the first air supply section 11 when the mating part 224 and the first limiting part 131 are engaged, and it can also be ensured that the outlet 2132 of the impeller cavity 213 corresponds to and is connected to the second air supply section 12 when the mating part 224 and the first limiting part 131 are engaged, thereby improving the reliability and stability of the connection between the outlet 2132 of the impeller cavity 213 and the first air supply section 11 and the second air supply section 12 respectively.

[0078] like Figure 2 and Figure 4As shown, according to some embodiments of the present invention, the outer side of the bracket 10 may have a receiving groove 15, the first driving member 40 may be disposed in the receiving groove 15, the output shaft of the first driving member 40 may pass through the groove wall of the receiving groove 15, and the output shaft of the first driving member 40 may be axially aligned with the air guide shell 20 (e.g., Figure 2 One end (as shown in the left and right directions) (e.g.) Figure 2 The connection shown on the right end, based on the normal rotation of the air guide shell 20 driven by the first driving component 40, can make full use of the internal space of the bracket 10 and reduce the space occupied by the first driving component 40 in the air supply assembly 100, which is conducive to the miniaturization of the air supply assembly 100.

[0079] The other end of the air guide housing 20 axial direction (such as Figure 2 The left end shown can have a rotating shaft, and the bracket 10 can have a shaft hole. Alternatively, the other end of the air guide shell 20 in the axial direction can have a shaft hole, and the bracket 10 can have a rotating shaft. Thus, the rotating shaft and the shaft hole can be rotatably engaged, so that the first driving member 40 can drive the air guide shell 20 to rotate relative to the bracket 10 between the first position and the second position. This allows the impeller cavity 213 to send air outward in different directions through the first air supply part 11 or the second air supply part 12, ensuring the air volume sent outward by the air supply assembly 100. At the same time, the air direction sent outward by the air supply assembly 100 can be switched, which is beneficial to realizing the direct air blowing function to the human body and can improve the user experience.

[0080] like Figure 2 and Figure 4 As shown, according to some embodiments of the present invention, the output shaft of the second driving member 50 and the output shaft of the first driving member 40 can be arranged in parallel. For example, the center lines of the output shafts of the second driving member 50 and the first driving member 40 can be arranged at intervals, that is, the impeller 30 in the impeller cavity 213 can be eccentrically arranged, which can optimize the airflow distribution in the impeller cavity 213. Moreover, the impeller 30 and the volute tongue 212 cooperate to reduce the local vortex in the impeller cavity 213 and improve the air supply efficiency of the air supply assembly 100. At the same time, the center line of the output shaft of the first driving member 40 and the rotation center line of the air guide shell 20 can coincide, so that the first driving member 40 can drive the air guide shell 20 to rotate normally.

[0081] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the air supply device 1000 according to an embodiment of the present utility model includes: a housing 200, an air supply assembly 100, and an air duct component 300. The housing 200 may be provided with an air inlet 203, a first air outlet 201, and a second air outlet 202. The air supply assembly 100 may be disposed inside the housing 200. The inlet 2131 of the impeller cavity 213 may be connected to the air inlet 203. The air duct component 300 may be disposed inside the housing 200, and the air duct component 300 may have a first air duct 301 and a second air duct 302. The first air duct 301 may be connected between the first air supply part 11 and the first air outlet 201, and the second air duct 302 may be connected between the second air supply part 12 and the second air outlet 202.

[0082] Driven by the air supply assembly 100, air can enter the impeller cavity 213 through the air inlet 203, and then flow out through the first air duct 301 or the second air duct 302. This allows the air supply device 1000 to supply air outward in different directions through the first air duct 301 or the second air duct 302, ensuring the air volume supplied by the air supply device 1000. At the same time, the air direction supplied by the air supply device 1000 can be switched, which is beneficial to achieving the function of direct airflow to the human body and improving the user experience.

[0083] By adopting the aforementioned air supply component 100, and with the outlet 2132 of the impeller cavity 213 of the air supply component 100 selectively connected to the first air duct 301 and the second air duct 302, the air supply device 1000 can independently supply air outward in different directions through the first air duct 301 or the second air duct 302. This ensures the air volume supplied by the air supply device 1000 and allows switching the direction of the air supplied by the air supply device 1000, which is beneficial for achieving the function of direct airflow to the human body and can improve the user experience.

[0084] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, according to some embodiments of the present invention, the air supply device 1000 can be a purifier, and the air supply device 1000 can include a purification component 400 (such as a filter). The housing 200 can have an air inlet chamber 204, which can be connected to the air inlet section 203 and the inlet 2131 of the impeller chamber 213. The purification component 400 can be disposed in the air inlet chamber 204 and can be disposed close to the air inlet section 203, so that the air can be purified before entering the impeller chamber 213, thereby improving the air purification effect and improving the performance and stability of the air supply device 1000.

[0085] like Figure 5 and Figure 6As shown, in some embodiments, both the air supply assembly 100 and the air duct component 300 can be disposed above the air inlet cavity 204, which is beneficial to realize the function of direct air blowing to the human body. The first air outlet 201 can be disposed on the top wall of the housing 200, so that the air duct component 300 can blow air upward through the first air outlet 201. The second air outlet 202 can be disposed on the side wall of the housing 200, so that the air duct component 300 can blow air forward through the second air outlet 202.

[0086] Alternatively, the first air outlet 201 can be located on the side wall of the housing 200, allowing the air duct component 300 to expel air forward through the first air outlet 201. The second air outlet 202 can be located on the top wall of the housing 200, allowing the air duct component 300 to expel air upward through the second air outlet 202. This allows switching the direction of the air supply device 1000 to deliver air outward and enables direct airflow to the human body, thus improving the user experience.

[0087] In this application, both the first air outlet 201 and the second air outlet 202 can be components of the air supply device 1000 for air outlet. It is understood that both the first air outlet 201 and the second air outlet 202 can be air outlets of the air supply device 1000, while the air inlet 203 can be components of the air supply device 1000 for air inlet. It is understood that the air inlet 203 can be air inlet of the air supply device 1000. Both the first air supply 11 and the second air supply 12 can be components of the air supply assembly 100 for air outlet. It is understood that both the first air supply 11 and the second air supply 12 can be air outlets of the air supply assembly 100.

[0088] It should be noted that the first air outlet 201 can be the front air outlet of the air supply device 1000, and a heater can be installed at the front air outlet to realize the function of blowing warm air when the air supply device 1000 blows air from the front. The second air outlet 202 can be the upper air outlet of the air supply device 1000, and a heater can be installed at the upper air outlet to realize the function of blowing warm air when the air supply device 1000 blows air from the top. The heater can be fixed on the air supply device 1000, or the heater can be movably installed on the air supply device 1000 so that the heater can be removed from the position of the air outlet, thereby improving the air supply performance of the air supply device 1000.

[0089] The following reference Figures 1-12To describe some specific embodiments of the present invention, the air supply device 1000 may include: a housing 200, an air supply assembly 100, an air duct component 300, and a purification component 400. The housing 200 may be provided with an air inlet 203, an air inlet cavity 204, a first air outlet 201, and a second air outlet 202. The air supply assembly 100 and the air duct component 300 may both be disposed within the housing 200 and located above the air inlet cavity 204. The air inlet 203 and the air supply assembly 100 may be connected through the air inlet 203. The purification component 400 may be disposed within the air inlet cavity 204 and disposed close to the air inlet 203. The air duct component 300 may have a first air duct 301 and a second air duct 302. The air supply assembly 100 may be connected to the first air outlet 201 separately through the first air duct 301, and the air supply assembly 100 may be connected to the second air outlet 202 separately through the second air duct 302.

[0090] The air supply assembly 100 may include: a bracket 10, an air guide shell 20, a first driving member 40, an impeller 30, and a second driving member 50. The bracket 10 may have an air supply zone, a partition 13, a first limiting part 131, and a second limiting part 14. The partition 13 can divide the air supply zone into a first air supply part 11 and a second air supply part 12. The first limiting part 131 may be located on the partition 13. The air guide shell 20 is rotatably disposed inside the bracket 10. The first driving member 40 may be disposed on the bracket 10, and the first driving member 40 may be connected to the air guide shell 20 to drive the air guide shell 20 to rotate relative to the bracket 10 between a first position and a second position.

[0091] The air guide shell 20 may include a volute 21 and a sealing shell 22. The volute 21 may define a wind turbine cavity 213. The wind turbine 30 may be disposed in the wind turbine cavity 213. The second driving member 50 may be disposed on the air guide shell 20. The second driving member 50 may be connected to the wind turbine 30. The second driving member 50 may drive the wind turbine 30 to rotate relative to the air guide shell 20. The inlet 2131 of the wind turbine cavity 213 may be connected to the air inlet cavity 204. The sealing shell 22 may be connected to the volute 21.

[0092] The sealing shell 22 may include a first baffle 221 and a second baffle 222 arranged at intervals, and the sealing shell 22 may have an opening 223, which may be located between the first baffle 221 and the second baffle 222. The opening 223 and the outlet 2132 of the impeller cavity 213 may correspond in position. The outlet 2132 of the impeller cavity 213 may be connected to the first air supply section 11 or the second air supply section 12 through the opening 223.

[0093] The second baffle 222 may be provided with a mating part 224. When the air guide shell 20 is in the first position, the first limiting part 131 may engage with the mating part 224 to stop and cooperate. At this time, the second baffle 222 may close the second air supply part 12, and the first baffle 221 may open the first air supply part 11 so that the outlet 2132 of the impeller cavity 213 and the first air supply part 11 are connected. It can be understood that the rotation of the impeller 30 can drive air to enter the air inlet cavity 204 through the air inlet part 203, and the air purified by the purification component 400 may enter the impeller cavity 213 through the inlet 2131 of the impeller cavity 213, and then enter the first air duct 301 through the outlet 2132 of the impeller cavity 213, the opening 223 of the sealing shell 22 and the first air supply part 11 in sequence, and flow out through the first air outlet 201, so as to realize the forward air supply of the air supply device 1000.

[0094] When the air guide shell 20 is in the second position, the second limiting part 14 can stop and cooperate with the mating part 224.

It can be understood that the rotation of the impeller 30 can drive air to enter the air inlet cavity 204 through the air inlet part 203, and the air purified by the purification component 400 can enter the impeller cavity 213 through the inlet 2131 of the impeller cavity 213, and then enter the second air duct 302 through the outlet 2132 of the impeller cavity 213, the opening 223 of the sealing shell 22 and the second air supply part 12 in sequence, and flow out through the second air outlet 202, so as to realize the upward air supply of the air supply device 1000.
