The third drive assembly 24 drives the volute 21 to rotate, so that the airflow outlet 21b is selectively connected to the first air outlet 11a or the second air outlet 11b. Please refer to Fig.13 When the volute 21 rotates to the first position C1, the airflow outlet 21b is connected to the first air outlet 11a, the airflow generated by the wind wheel 22 can flow out from the airflow outlet 21b and flow to the first air outlet 11a, and the cover assembly 12 is in a closed state of closing the second air outlet 11b; please refer to Fig.16 When the volute 21 rotates to the second position C2, the first drive assembly 13 drives the cover assembly 12 to switch from the closed state to the open state of opening the second air outlet 11b, and the airflow outlet 21b is connected with the second air outlet 11b, and the airflow generated by the wind wheel 22 can flow out from the airflow outlet 21b and flow to the second air outlet 11b. In other words, when it is not necessary to discharge air through the second air outlet 11b, the cover assembly 12 remains in the closed state. When the airflow outlet 21b is connected with the second air outlet 11b, that is, when it is necessary to discharge air through the second air outlet 11b, the cover assembly 12 is driven by the first drive assembly 13 to switch from the closed state to the open state. After the cover assembly 12 is opened, the airflow can flow out from the second air outlet 11b.

[0071] Another embodiment of the present application provides an electrical device, see Figures 8 to 10 , Fig.13 , Fig.15 and Fig.16 The electrical device includes a housing 30 and an air outlet mechanism as described in any embodiment of the present application. The housing 30 has a housing cavity and a first mounting port 30a, a second mounting port 30b and an air inlet 30c connected to the housing cavity; the air outlet mechanism is arranged in the housing cavity, the first air outlet 11a is connected to the outside through the first mounting port 30a, the second air outlet 11b is connected to the outside through the second mounting port 30b, an air flow path is formed between the air inlet 30c and the air flow inlet 21a, and the air flow inlet 21a is located downstream of the air inlet 30c along the air flow path, that is, the air flow from the outside enters the housing cavity from the air inlet 30c, and flows into the air flow inlet 21a along the air flow path between the air inlet 30c and the air flow inlet 21a.

[0072] The air outlet mechanism of the embodiment of the present application is provided with a first air outlet 11a and a second air outlet 11b on the shell 11, one of the first air outlet 11a and the second air outlet 11b is provided on one side of the shell 11, and the other of the first air outlet 11a and the second air outlet 11b is provided on the top of the shell 11, and the third driving component 24 is drivingly connected to the volute 21, so as to drive the volute 21 to rotate so that the airflow outlet 21b of the volute 21 is selectively connected to the first air outlet 11a or the second air outlet 11b, when the airflow outlet 21b is connected to the first air outlet 11a, The airflow generated by the wind wheel 22 can flow out from the first air outlet 11a. When the airflow outlet 21b is connected to the second air outlet 11b, the first driving component 13 drives the surface cover component 12 to switch from a closed state of closing the second air outlet 11b to an open state of opening the second air outlet 11b, so that the airflow generated by the wind wheel 22 can flow out from the second air outlet 11b. That is to say, the air outlet mechanism of the embodiment of the present application has two air outlet modes, one is to discharge air from one side of the shell 11, and the other is to discharge air from the top of the shell 11. Thereby, the user's needs for multi-directional air outlet can be met.

[0073] It should be noted that in the embodiment of the present application, when air needs to be discharged through the second air outlet 11b, the third drive component 24 can first drive the volute 21 to rotate, and the second drive component 23 can then drive the surface cover component 12 to switch from a closed state to an open state. The second drive component 23 can first drive the surface cover component 12 to switch from a closed state to an open state, and the third drive component 24 can then drive the volute 21 to rotate. The third drive component 24 can also drive the volute 21 to rotate while the second drive component 23 drives the surface cover component 12 to switch from a closed state to an open state.

[0074] See also Figures 1 to 4 In the embodiment of the present application, an air outlet grille 14 may be provided at the first air outlet 11a to prevent external debris from entering the air outlet mechanism.

[0075] In one embodiment, please refer to Fig.13 and Fig.16 The shell 11 also has a first air duct 11c and a second air duct 11d, the first air outlet 11a is arranged at the end of the first air duct 11c along the air flow direction, and the second air outlet 11b is arranged at the end of the second air duct 11d along the air flow direction; the third driving component 24 drives the volute 21 to rotate, so that the airflow outlet 21b is selectively connected with the beginning of the first air duct 11c along the air flow direction or the beginning of the second air duct 11d along the air flow direction. That is to say, when the airflow outlet 21b is connected with the beginning of the first air duct 11c along the air flow direction, the airflow generated by the wind wheel 22 flows out from the airflow outlet 21b and flows into the first air duct 11c, and then flows along the first air duct 11c to the first air outlet 11a, that is, the airflow outlet 21b is connected with the first air outlet 11a through the first air duct 11c. When the airflow outlet 21b is connected to the beginning of the second air duct 11d along the airflow flow direction, the airflow generated by the wind wheel 22 flows out from the airflow outlet 21b and flows into the second air duct 11d, and then flows to the second air outlet 11b along the second air duct 11d, that is, the airflow outlet 21b is connected to the second air outlet 11b through the second air duct 11d. The first air duct 11c and the second air duct 11d can facilitate the flow of the airflow generated by the wind wheel 22, thereby improving the air outlet efficiency of the air outlet mechanism.

[0076] In one embodiment, please refer to Fig.13 When the airflow outlet 21b is connected to the beginning of the first air duct 11c along the airflow direction, the volute 21 closes the beginning of the second air duct 11d along the airflow direction; see Fig.16 When the airflow outlet 21b is connected to the starting end of the second air duct 11d along the airflow direction, the volute 21 closes the starting end of the first air duct 11c along the airflow direction.

[0077] Specifically, when the face cover assembly 12 is in a closed state, there may still be some gaps between the face cover assembly 12 and the shell 11. Therefore, when the airflow outlet 21b is connected with the starting end of the first air duct 11c along the airflow flow direction, the volute 21 can prevent the external airflow from being sucked back into the second air duct 11d from the gap between the face cover assembly 12 and the shell 11 to cause return air by closing the starting end of the second air duct 11d along the airflow flow direction. When the airflow outlet 21b is connected with the starting end of the second air duct 11d along the airflow flow direction, the volute 21 can prevent the external airflow from being sucked back into the first air duct 11c from the first air outlet 11a to cause return air by closing the starting end of the first air duct 11c along the airflow flow direction. Therefore, the user experience can be improved.

[0078] In one embodiment, please refer to Figures 1 to 4 , Fig.13 and Fig.16 The first air outlet 11a is arranged on one side of the shell 11, and the second air outlet 11b is arranged on the top of the shell 11; the first driving assembly 13 includes a driving motor 131 and a transmission member 132, the driving motor 131 is drivingly connected to the transmission member 132, the transmission member 132 is drivingly connected to the surface cover assembly 12, the driving motor 131 drives the surface cover assembly 12 to rise and fall by driving the transmission member 132, so that the surface cover assembly 12 selectively opens or closes the second air outlet 11b.

[0079] Specifically, compared with the air outlet arranged on one side of the shell 11, dust, debris, etc. are more likely to enter the shell 11 from the air outlet arranged on the top of the shell 11. Therefore, the second air outlet 11b is arranged at the top of the shell 11. When the second air outlet 11b is not needed, the second air outlet 11b can be closed by using the face cover assembly 12 to prevent dust, debris, etc. from entering the shell 11 from the second air outlet 11b.

[0080] In one embodiment, please refer to Figure 4 , Fig.13 and Fig.16 The face cover assembly 12 includes a face cover 121 and a lifting platform 122 connected to the face cover 121, and a transmission member 132 is in transmission connection with the lifting platform 122. When the face cover assembly 12 is in a closed state, the lifting platform 122 is located in the housing 11, and the face cover 121 closes the second air outlet 11b; when the driving motor 131 drives the transmission member 132 to drive the face cover assembly 12 to move upward in the vertical direction to a preset position, at least a part of the structure of the lifting platform 122 extends out from the second air outlet 11b, and the face cover 121 opens the second air outlet 11b.

[0081] Specifically, the cover 121 is used to open or close the second air outlet 11b, and the lifting platform 122 is used to cooperate with the transmission member 132 to selectively open or close the second air outlet 11b by driving the cover 121 to rise and fall. Fig.13 When the cover assembly 12 is in a closed state, the cover 121 contacts the top surface of the housing 11. Fig.16 When the driving motor 131 drives the transmission member 132 to drive the face cover assembly 12 to move upward in the vertical direction to a preset position, the face cover 121 is separated from the top surface of the shell 11, and the face cover 121 opens the second air outlet 11b. The airflow flowing out of the second air outlet 11b can flow out from the gap between the face cover 121 and the top wall of the shell 11, which is equivalent to forming a circumferential air outlet structure between the face cover 121 and the shell 11. As a result, the airflow can be evenly diffused in all directions, so that the air outlet mechanism can have a better air outlet effect.

[0082] In one embodiment, please refer to Figure 4 , Figures 13 to 16 The lifting platform 122 has a accommodating cavity 122a and an avoidance opening 122b connected to the accommodating cavity 122a, and the transmission member 132 includes a gear 1321 and a rack 1322; the driving motor 131 and the gear 1321 are both arranged in the accommodating cavity 122a, and the output end of the driving motor 131 is drivingly connected to the gear 1321; one end of the rack 1322 is arranged in the shell 11, and a part of the structure of the rack 1322 extends from the avoidance opening 122b into the accommodating cavity 122a and meshes with the gear 1321.

[0083] Specifically, the drive motor 131 and the gear 1321 are arranged in the accommodating cavity 122a to protect the drive motor 131 and the gear 1321, and the rack 1322 extends into the accommodating cavity 122a from the avoidance opening 122b to guide the cover assembly 12 to a certain extent.

[0084] Also, see Figure 4 and Fig.14 In order to facilitate fixing the driving motor 131 , a fixing bracket 15 may be further provided in the accommodating cavity 122 a , and the driving motor 131 is provided on the fixing bracket 15 .

[0085] In some embodiments, the drive motor 131 may be disposed in the accommodating cavity 122a, the gear 1321 and the rack 1322 may be disposed in the shell 11, and the output end of the drive motor 131 may extend from the avoidance opening 122b and be driven and connected to the gear 1321. Alternatively, the lifting platform 122 may not be provided with the accommodating cavity 122a, which means that the drive motor 131 may be directly exposed in the shell 11.

[0086] In some implementations, the rack 1322 may be disposed on the lifting platform 122 , and the driving motor 131 may be disposed in the housing 11 .

[0087] It is understandable that the transmission member 132 is not limited to a transmission structure in which a gear 1321 and a rack 1322 cooperate. In some embodiments, the transmission member 132 may be other types of transmission structures. For example, the transmission member 132 may be a transmission structure in which a turbine and a worm gear cooperate, or a transmission structure in which multiple gears 1321 cooperate.

[0088] In one embodiment, please refer to Figure 4 , Fig.13 and Fig.16 The shell 11 includes a main body 111 and an air guide 112. The main body 111 has a receiving space that is connected from top to bottom. One side of the receiving space has a first air outlet 11a, and a second air duct 11d is formed between the second air inlet 11f and the second air outlet 11b; the air guide 112 extends into the receiving space from a through-hole at the top of the receiving space, and the air guide 112 cooperates with the main body 111 to form a first air duct 11c in the receiving space that extends upward from the through-hole at the bottom of the receiving space to the first air outlet 11a, and the bottom end of the first air duct 11c has a first air inlet 11e; the wind wheel device 20 is arranged at the bottom of the air outlet device 10, and the third driving component 24 drives the volute 21 to rotate, so that the air flow outlet 21b is selectively connected to the first air inlet 11e or the second air inlet 11f. That is to say, when the air flow outlet 21b is connected with the first air inlet 11e, the air flow generated by the wind wheel 22 can flow upward from the first air inlet 11e along the first air duct 11c, and flow out from the first air outlet 11a arranged on one side of the shell 11; when the air flow outlet 21b is connected with the second air inlet 11f, the air flow generated by the wind wheel 22 can flow upward from the second air inlet 11f along the second air duct 11d, and flow out from the second air outlet 11b arranged at the top of the second air duct 11d.

[0089] In one embodiment, please refer to Figure 6 and Figure 7 The volute 21 includes a first half shell 211, a second half shell 212, a first auxiliary shell 213 and a second auxiliary shell 214. The first half shell 211 and the second half shell 212 both have a notch and an air flow inlet 21a. The first half shell 211 and the second half shell 212 are butted against each other. The air flow inlet 21a of the first half shell 211 and the air flow inlet 21a of the second half shell 212 are respectively located on opposite sides of the axial direction of the wind wheel 22. The notch of the first half shell 211 and the notch of the second half shell 212 are butted against each other to form an air flow outlet 21b located on one side of the radial direction of the wind wheel 22. The first auxiliary shell 213 and the second auxiliary shell 214 are respectively arranged on opposite sides of the air flow outlet 21b, that is, the wind wheel device 20 can be a centrifugal wind wheel device. When the air flow outlet 21b is connected to the first air inlet 11e, the second auxiliary shell 214 closes the second air inlet 11f. When the air flow outlet 21b is connected to the second air inlet 11f, the first auxiliary shell 213 closes the first air inlet 11e.

[0090] In one embodiment, please refer to Figure 6 and Figure 7 The wind wheel device 20 includes a first bracket 25 and a second bracket 26, and the volute 21 also includes a first rotating connection member 215 rotatably connected to the first bracket 25 and a second rotating connection member 216 rotatably connected to the second bracket 26; the first rotating connection member 215 is connected to the first half shell 211, the second rotating connection member 216 is connected to the second half shell 212, and the third driving assembly 24 is drivingly connected to the first rotating connection member 215.

[0091] Specifically, the volute 21 is actually disposed between the first bracket 25 and the second bracket 26 and supported by the first bracket 25 and the second bracket 26 . The third driving assembly 24 is driven and connected to the first rotating connector 215 , so as to drive the volute 21 to rotate.

[0092] In some embodiments, the third drive assembly 24 may also be drivingly connected to the second rotating connection member 216 .

[0093] In one embodiment, please refer to Fig.10 and Fig.13 The electrical device further includes a filter device 40, which is disposed in the accommodating cavity and located on the air flow path between the air inlet 30c and the air inlet 21a. In other words, the airflow entering the accommodating cavity from the air inlet 30c can be filtered by the filter device 40 before flowing into the air inlet 21a, thereby enabling the electrical device to have an air management function of purifying the air, thereby increasing the diversity of the functions of the electrical device.

[0094] In one embodiment, please refer to Fig.10 and Fig.13 There is a gap between the bottom wall of the housing 30 and the supporting plane, the bottom wall has an air inlet 30c, and the filter device 40 is placed on the bottom wall. The supporting plane refers to a plane supporting the electrical equipment, such as the ground. In other words, the air inlet 30c can be set at the bottom of the electrical equipment. Since there is a gap between the bottom wall of the housing 30 and the supporting plane, the air flow from the outside can flow from the gap between the bottom wall of the housing 30 and the supporting plane to the air inlet 30c.

[0095] In one embodiment, please refer to Fig.10 and Fig.13The electrical device also includes a base 60 arranged in the accommodating cavity, the base 60 includes a bottom plate 61 with a through hole 61a and a plurality of supporting legs 62 connected to the bottom plate 61, the base 60 is placed on the bottom wall, and an accommodating space for accommodating the filter device 40 is formed between the bottom plate 61 and the bottom wall, relative to the filter device 40 being located between the bottom wall of the outer shell 30 and the bottom plate 61 of the base 60, the wind wheel device 20 is placed on the bottom plate 61, and the airflow flowing into the outer shell 30 from the air intake port 30c is filtered by the filter device 40, and then flows from the through hole 61a on the bottom plate 61 to the airflow inlet 21a of the wind wheel device 20.

[0096] In one embodiment, please refer to Fig.13 The air outlet device 10 further includes a heating component 16, which is disposed in the first air duct 11c and located at one end of the first air duct 11c close to the first air outlet 11a. The heating component 16 can heat the airflow before it flows out of the first air outlet 11a, thereby exhausting warm air to the outside. That is to say, the electrical device of the embodiment of the present application has a heating function in addition to the air purification function, thereby further improving the diversity of the functions of the electrical device.

[0097] In one embodiment, please refer to Figure 3 , Figure 4 Fig.13 , Fig.15 and Fig.16 , the heating component 16 is movably disposed in the first air duct 11c; the air outlet device 10 further includes a fourth driving component 17, which is drivingly connected to the heating component 16 to drive the heating component 16 to move to the air flow path in the first air duct 11c or to move away from the air flow path in the first air duct 11c. That is, when the heating component 16 is needed, the fourth driving component 17 can drive the heating component 16 to move to the air flow path in the first air duct 11c, so that the heating component 16 can heat the air flow in the first air duct 11c; when the heating component 16 is not needed, the fourth driving component 17 can drive the heating component 16 to move away from the air flow path in the first air duct 11c, so that the air flow in the first air duct 11c can flow out from the first air outlet 11a faster.

[0098] In one embodiment, please refer to Figure 4 The heating assembly 16 includes a mounting bracket 161 and a heating element 162 . The mounting bracket 161 is rotatably disposed in the first air duct 11 c . The heating element 162 is disposed on the mounting bracket 161 . The fourth driving assembly 17 is drivingly connected to the mounting bracket 161 .

[0099] Specifically, the heating element 162 can be a positive temperature coefficient thermistor (PTC) or a heating element such as a heating wire. When the heating component 16 is needed, the fourth driving component 17 can drive the heating component 16 to rotate and move the heating component 16 to the air flow path in the first air duct 11c. Similarly, when the heating component 16 is not needed, the fourth driving component 17 can drive the heating component 16 to rotate and move the heating component 16 away from the air flow path in the first air duct 11c.

[0100] For further information, see Fig.13 , Fig.15 and Fig.16 , a portion of the inner wall of the first air duct 11c near the first air outlet 11a protrudes outward to form a receiving groove 11g; when the fourth driving component 17 drives the heating component 16 to move away from the air flow path in the first air duct 11c, the heating component 16 is received in the receiving groove 11g. When the heating component 16 is not needed, the heating component 16 is received in the receiving groove 11g to prevent the heating component 16 from obstructing the air flow in the first air duct 11c.

[0101] In another embodiment, the mounting bracket 161 may also be movably arranged in the first air duct 11c. Specifically, the mounting bracket 161 may be movably moved horizontally or vertically. The fourth driving component 17 drives the heating component 16 to move horizontally, so that the heating component 16 moves to the airflow path in the first air duct 11c or moves away from the airflow path in the first air duct 11c.

[0102] In some embodiments, the heating component 16 can also be fixed on the air flow path in the air duct, that is, the heating component 16 cannot be removed from the air flow path in the air duct. When the heating component 16 is not needed, the heating component 16 remains in a non-working state. When the heating component 16 is needed, the heating component 16 is switched to a working state.

[0103] In one embodiment, please refer to Figures 10 to 13 The electrical device further includes a humidifying device 50 disposed in the accommodating cavity, and a mist outlet end of the humidifying device 50 is connected to the outside.

[0104] Specifically, the humidifying device 50 can discharge water mist to the outside, thereby humidifying the surrounding environment. That is to say, by providing the humidifying device 50, the electrical equipment can have a humidification function, thereby further improving the functional diversity of the electrical equipment.

[0105] In one embodiment, please refer to Figures 11 to 13The humidifying device 50 includes a water tank 51, a mist outlet pipe 52 and an atomizing assembly 53. The mist outlet pipe 52 has a first mist outlet channel 52a. The first mist outlet channel 52a has a first mist inlet 52b and a first mist outlet 52c. The water outlet 51a and the first mist inlet 52b of the water tank 51 are both connected to the atomizing assembly 53, and the first mist outlet 52c is connected to the first air outlet 11a.

[0106] Specifically, the atomizing assembly 53 may be an oscillating atomizing assembly 53, for example, see Fig.11 and Fig.12 The oscillating atomizing assembly 53 includes a water receiving box 531, an oscillating plate 532 and a fan 533. After the water in the water tank 51 flows into the water receiving box 531, the oscillating plate 532 oscillates the water into fine water particles, and then the water mist containing the fine water particles is blown from the first mist inlet of the mist outlet pipe 52 into the first mist outlet channel 52a by the fan 533. The atomizing assembly 53 can also be a microporous atomizing assembly 53. The atomizing method of the microporous atomizing assembly 53 is roughly the same as that of the oscillating atomizing assembly 53. The difference is that the microporous atomizing assembly 53 absorbs the water in the water tank 51 onto the oscillating plate 532 through a sponge rod for oscillation.

[0107] In this embodiment, the first mist outlet 52c of the first mist outlet channel 52a is connected to the first air outlet 11a, that is, the water mist entering the first mist outlet channel 52a from the first mist inlet 52b is discharged through the first air outlet 11a, which is equivalent to the humidifying device 50 and the air outlet device 10 sharing the first air outlet 11a, or in other words, the water mist generated by the humidifying device 50 and the air flow generated by the air outlet device 10 can both be discharged from the first installation port 30a on the cabinet 30. Therefore, there is no need to set a separate water mist outlet for the humidifying device 50 on the cabinet 30.

[0108] It is understandable that, in some embodiments, a water mist outlet may be provided on the cabinet 30 , and the first mist outlet 52 c is connected to the outside through the water mist outlet. That is, the water mist generated by the humidifying device 50 may also be discharged from the water mist outlet separately provided on the cabinet 30 .

[0109] Also, see Fig.10 The atomization assembly 53 can be set at a position close to the front side of the cabinet 30. At the same time, a disassembly opening 30d corresponding to the position of the water tank 51 is set on the side wall on the front side of the cabinet 30, and a decorative panel 70 rotatably or detachably connected to the cabinet 30 is set outside the cabinet 30. After the decorative panel 70 is opened, the user can remove the water tank 51 from the disassembly opening 30d to change the water.

[0110] In one embodiment, please refer to Figure 3 , Figure 4 and Fig.13The air outlet device 10 further includes an air outlet grille 14 disposed at the first air outlet 11a, the air outlet grille 14 having a second mist outlet channel 14a, the second mist outlet channel 14a having a second mist inlet 14b and a second mist outlet 14c, and the first mist outlet 52c is connected to the second mist inlet 14b. In other words, the water mist generated by the humidifying device 50 can enter the second mist outlet channel 14a from the second mist inlet 14b of the air outlet grille 14, and then be discharged from the second mist outlet 14c on the air outlet grille 14.

[0111] In one embodiment, please refer to Fig.13 When the electrical device is in the heating mode, the airflow outlet 21b is connected to the beginning of the first air duct 11c along the airflow direction, the heating component 16 is located on the airflow path in the first air duct 11c, and the heating component 16 and the wind wheel device 20 are in working state. Fig.13 When the electrical device switches from the warm air mode to the humidification mode, the fourth driving component 17 drives the heating component 16 to move away from the air flow path in the first air duct 11c, and the humidification device 50 and the wind wheel device 20 are in working state.

[0112] Specifically, for the heating component 16 that is movably arranged in the first air duct 11c, when the electrical device is in the warm air mode, the heating component 16 is located on the air flow path in the first air duct 11c, the heating component 16 and the wind wheel device 20 are in working state, and the air flow generated by the wind wheel device 20 flows into the first air duct 11c from the beginning of the first air duct 11c along the air flow direction, and flows out from the first air outlet 11a after being heated by the heating component 16 in the first air duct 11c. When the electrical device is switched from the warm air mode to the humidification mode, the fourth driving component 17 drives the air flow device 20 to rotate. The dynamic heating component 16 is removed from the air flow path in the first air duct 11c, the humidifying device 50 and the wind wheel device 20 are in working state, and the water mist generated by the humidifying device 50 merges with the air flow generated by the wind wheel device 20 at the first air outlet 11a. Since the heating component 16 has been removed from the air flow path in the first air duct 11c, the air flow in the first air duct 11c can flow out from the first air outlet 11a faster. Therefore, relying on the air flow generated by the wind wheel device 20, the water mist generated by the humidifying device 50 can be transported farther and the humidification effect is better.

[0113] In one embodiment, please refer to Fig.15 When the electrical device is in the first purification mode, the airflow outlet 21b is connected to the beginning of the first air duct 11c along the airflow direction, the heating component 16 is located on the airflow path in the first air duct 11c, and the wind wheel device 20 is in working state; please refer to Fig.13, when the electrical device is switched from the first purification mode to the humidification mode, the fourth driving component 17 drives the heating component 16 to move away from the air flow path in the first air duct 11c, and the humidifying device 50 and the wind wheel device 20 are in working state. That is to say, when the electrical device is in the first purification mode, the air flow generated by the wind wheel device 20 still flows out through the first air outlet 11a, and the heating component 16 can also be located on the air flow path in the first air duct 11c, but the heating component 16 is in a non-working state, that is, the heating component 16 does not heat the air flow in the first air duct 11c, and when the electrical device is switched from the first purification mode to the humidification mode, the fourth driving component 17 drives the heating component 16 to move away from the air flow path in the first air duct 11c.

[0114] In some embodiments, when the electrical device is in the first purification mode, the heating component 16 may not be located on the air flow path in the first air duct 11 c.

[0115] In one embodiment, please refer to Fig.16 When the electrical device is in the second purification mode, the airflow outlet 21b is connected to the beginning of the second air duct 11d along the airflow direction, and the second air outlet 11b is in an open state.

[0116] Specifically, when the electrical equipment switches from the warm air mode to the second purification mode, the heating component 16 switches to a non-working state. When the electrical equipment switches from the humidification mode to the second purification mode, the humidification device 50 can switch to a non-working state or continue to maintain a working state, which is equivalent to that air purification and humidification can be carried out simultaneously.

[0117] The electrical device in the embodiment of the present application can be any electrical device that relies on the airflow generated by the wind wheel 22 to achieve air outlet, such as a purifier, a heater, a box-type cooling fan, and a smart bedside table with an air outlet function.

[0118] The various embodiments / implementations provided in this application can be combined with each other without causing any contradiction.

[0119] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application are included in the protection scope of the present application.
