[0043] Reference Figure 1 and Figure 4A mobile air conditioner according to an embodiment of the present invention includes an air outlet device 100, wherein the air outlet device 100 includes an air duct housing 110 and an air guide assembly 120, the air duct housing 110 is provided with an air cavity 111 inside, an air outlet 112 is provided on one side of the air cavity 111, the wind blown out of the mobile air conditioner flows along the air cavity 111 and is blown out from the air outlet 112, the air guide assembly 120 is installed at the air outlet 112, the air guide assembly 120 is rotatably connected to the air duct housing 110, and the air guide assembly 120 rotates on the air duct housing 110 to close or open the air outlet 112, specifically, the air outlet 112 is closed or opened by the air guide assembly 120.

[0044] The air guide component 120 rotates and opens the air outlet 112, allowing the mobile air conditioner to operate normally and blow air into the room; the air guide component 120 rotates and closes the air outlet 112. After the mobile air conditioner stops working, the air outlet 112 is closed to prevent dust from entering the mobile air conditioner along the wind cavity 111.

[0045] In some embodiments, reference Figure 2 and Figure 7 The air guide assembly 120 is provided with an air outlet 124, referring to Figure 3 and Figure 7 When the mobile air conditioner is in the turned-on state, the wind in the wind cavity 111 will be blown out through the air outlet 124 in the direction indicated by the arrow.

[0046] In some embodiments, reference Figure 2 The air outlet device 100 includes an air duct housing 110 and an air guide assembly 120. The air guide assembly 120 is installed at the air outlet 112. The air guide assembly 120 includes an air outlet area 121 and a shielding area 122. The air guide assembly 120 is close to the air outlet frame 113 and rotates along the surface of the air outlet frame 113 so that the air outlet area 121 covers the air outlet 112, thereby opening the air outlet 112; or the shielding area 122 covers the air outlet 112, thereby sealing the air outlet 112.

[0047] Specifically, refer to Figure 3 In the first embodiment of the present invention, the air guide assembly 120 is embedded in the air cavity 111 and rotates along the inner surface of the air cavity 111 so that the air outlet area 121 or the shielding area 122 alternately covers the air outlet 112 .

[0048] The air guide assembly 120 rotates along the inner surface of the wind cavity 111. When the mobile air conditioner is turned on, the air outlet area 121 of the air guide assembly 120 rotates to above the air outlet 112, and the wind blown out from the mobile air conditioner passes through the air outlet area 121 and is blown out to the outdoor environment. When the mobile air conditioner is turned off, the shielding area 122 of the air guide assembly 120 covers above the air outlet 112 to block dust from the outdoor environment and prevent dust from falling into the interior of the mobile air conditioner.

[0049] In this embodiment, refer to Figure 3 An air outlet frame 113 is provided inside the air duct housing 110, and an air cavity 111 is formed inside the air outlet frame 113. An air outlet 112 is provided on one side of the air cavity 111. The wind blown out of the mobile air conditioner flows into the air cavity 111 and is blown out from the air outlet 112. The air outlet frame 113 is in a long strip shape. In the cross section, the inner wall of the air cavity 111 is in an arc shape. The air guide component 120 is built into the air cavity 111, and the outer surface of the air guide component 120 rotates close to the inner surface of the air cavity 111. Specifically, the air guide component 120 rotates in the air cavity 111, so that the air outlet area 121 or the shielding area 122 alternately covers the air outlet 112, thereby opening or sealing the air outlet 112.

[0050] In other embodiments, the air guide assembly 120 can also be wrapped around the outside of the air outlet frame 113, with the inner surface of the air guide assembly 120 close to the outer surface of the air outlet frame 113, and rotate around a fixed rotation axis outside the air outlet frame 113, so that the air outlet area 121 or the shielding area 122 alternately covers the air outlet 112, thereby opening or sealing the air outlet 112. When the mobile air conditioner is turned on, the air outlet area 121 covers the air outlet 112, and the air flow is blown out through the air outlet 112. When the mobile air conditioner is turned off, the shielding area 122 covers the air outlet 112 to prevent dust from falling in.

[0051] In addition, since the air guide component 120 can move relative to the air duct housing 110, the air outlet area 121 can move to different angles, so that the air guide component 120 can effectively adjust the air outlet angle during the rotation process to meet the user's needs for different air outlet angles.

[0052] In some embodiments, the air outlet area 121 is provided with an air outlet grille 123, and the holes in the air outlet grille 123 are air outlet holes 124. The airflow entering the air cavity 111 gathers in the air cavity 111, and finally blows into the environment through the air outlet grille 123. After being processed by the air outlet grille 123, the blown airflow becomes softer.

[0053] In some specific embodiments, along the rotation direction of the air guide assembly 120 , the shielding area 122 is disposed on both sides or one side of the air outlet area 121 .

[0054] Reference Figure 3 In the first embodiment, the shielding area 122 is only provided on one side of the air outlet area 121. Compared with the structure provided on both sides, the structure size of the entire air guide assembly 120 can be reduced, and the processing cost can be reduced. It should be understood that in some embodiments, the shielding area 122 is provided on both sides of the air outlet area 121, which also belongs to a specific implementation method disclosed by the present invention.

[0055] In the second embodiment of the present invention, referring to Figures 4 to 7 The air outlet device 100 includes an air duct housing 110 and an air guide assembly 120. An air cavity 111 is provided inside the air duct housing 110. An air outlet 112 is provided on one side of the air cavity 111. The air blown out of the mobile air conditioner flows along the air cavity 111 and is blown out from the air outlet 112. The air guide assembly 120 is installed at the air outlet 112. The air guide assembly 120 includes a rotating member 125 and a plurality of air guide blades 126. The rotating member 125 is rotatably connected to the outer wall of the air duct housing 110. An air outlet slot 1253 is provided in the middle of the rotating member 125. The air guide blades 126 are located in the air outlet slot 1253. The plurality of air guide blades 126 are arranged side by side. The air guide blades 126 are rotatably connected to the rotating member 125. Specifically, the air guide blades 126 rotate circumferentially around a fixed rotation axis within the range of the air outlet slot 1253. Figure 7 , the rotating member 125 rotates upward to open two adjacent air guide blades 126 and form an air outlet 124; Figure 4 , the rotating member 125 rotates downward to close the two adjacent air guide blades 126 and seal the air outlet 112 .

[0056] Reference Figure 5 and Figure 6 The air guide assembly 120 rotates on the air duct housing 110, and the air guide blades 126 rotate in the air outlet slot 1253 as the air guide assembly 120 rotates, thereby changing the angle, so that the air guide blades 126 gradually close or open to each other. Specifically, refer to Figure 7 , start the mobile air conditioner, the rotating member 125 swings upward, so that the air guide blades 126 gradually open and form the air outlet 124; and when the mobile air conditioner is turned off, refer to Figure 5 The rotating member 125 swings downward, causing the adjacent air guide blades 126 to gradually close, thereby covering the entire air outlet 112, thereby preventing dust in the external environment from falling into the interior of the mobile air conditioner.

[0057] It should be mentioned that in other embodiments, the rotating member 125 rotates downward to form an air outlet 124 between two adjacent air guide blades 126, and the rotating member 125 rotates upward to close the two adjacent air guide blades 126 and seal the air outlet 112. This embodiment should also be considered as a specific implementation of the technical solution of the present invention.

[0058] Specifically, in some embodiments, referring to Figure 5The air guide assembly 120 further includes a mounting plate 127, which is fixed to the air duct housing 110. Specifically, the mounting plate 127 can be fixed to the air duct housing 110 by welding or the like, or the mounting plate 127 and the air duct housing 110 can be integrally formed. The mounting plate 127 is provided with a guide rail 1271, and the air guide blade 126 is provided with a sliding member 1262. The sliding member 1262 is inserted into the guide rail 1271 and slides along the guide rail 1271. Since the rotation axis of the air guide blade 126 is provided on the rotating member 125, when the rotating member 125 swings, the rotation of the air guide blade 126 will be changed. The relative distance of the axis relative to the sliding member 1262 is the trend, but the rotation axis of the air guide vane 126 and the sliding member 1262 are fixed relative to the air guide vane 126, therefore, the distance between the rotation axis and the sliding member 1262 cannot be changed, then when the rotating member 125 rotates, the sliding member 1262 will be driven to change position, and the guide rail 1271 is used to guide the moving path of the sliding member 1262, so that the sliding member 1262 moves on the guide rail 1271 and the entire air guide vane 126 rotates around the rotation axis, thereby achieving the closing or opening between two adjacent air guide vanes 126. It should be mentioned that the mounting plate 127 is fixed to the air duct housing 110 by welding, and in addition, the mounting plate 127 can also be integrally formed with the air duct housing 110.

[0059] In some embodiments, reference Figure 6 The guide rail 1271 is an arc with the rotation axis of the air guide blade 126 as the center. When the mobile air conditioner is started, the rotating member 125 swings upward, thereby driving the sliding member 1262 on the air guide blade 126 to slide in the guide rail 1271. Specifically, it moves and swings down along the arc with the rotation axis of the air guide blade 126 as the center, so that the air guide blade 126 rotates around the rotation axis, and the air guide blades 126 gradually open and form the air outlet 124. When the mobile air conditioner is turned off, the rotating member 125 swings downward, and the sliding member 1262 swings up along the guide rail 1271, and the adjacent air guide blades 126 gradually close, thereby covering the entire air outlet 112, and preventing dust in the external environment from falling into the mobile air conditioner. The guide rail 1271 is set to be an arc with the rotation axis as the center to avoid interference.

[0060] Reference Figure 6 In some embodiments, a rotating shaft 1261 is provided at at least one end of the air guide blade 126, and the rotating shaft 1261 is inserted into the rotating member 125. The air guide blade 126 rotates around the rotating shaft 1261 as the rotating axis. In actual use, the rotating member 125 rotates to make the sliding member 1262 slide in the guide rail 1271, thereby driving the air guide blade 126 to rotate around the rotating shaft 1261, thereby opening the air outlet 112 or sealing the air outlet 112.

[0061] In order to make the air guide vane 126 more firmly inserted on the rotating member 125 and make the air guide vane 126 more stable during the rotation process, in some embodiments, the rotating member 125 is provided with a mounting block 1254, and the rotating shaft 1261 is inserted in the mounting block 1254, and the rotating shaft 1261 rotates relative to the mounting block 1254. The mounting block 1254 for inserting the rotating shaft 1261 is provided on the rotating member 125, and the rotating shaft 1261 is inserted into the mounting block 1254 to make the air guide vane 126 rotate around the rotating shaft 1261, so that the movement is more reliable. In some embodiments, the rotating shafts 1261 are provided at both ends of the air guide vane 126, and are inserted into the mounting block 1254, which greatly improves the reliability of the rotation of the air guide vane 126.

[0062] Reference Figure 4 In some embodiments, the rotating member 125 includes a mounting frame 1252 and a driving arm 1251. One end of the driving arm 1251 is rotatably connected to the air duct housing 110, and the other end is fixed to the mounting frame 1252. The air outlet slot 1253 is provided on the mounting frame 1252, and the upper surface of the mounting frame 1252 is configured as an arc surface. When the air guide blade 126 is opened to form the air outlet hole 124, when the wind blows out from the upper surface of the mounting frame 1252, the arc surface can increase the air outlet area, so that the air outlet effect is better.

[0063] In some embodiments, the air guide assembly 120 in the mobile air conditioner is connected to a driving mechanism, which is used to drive the air guide assembly 120 to rotate on the air duct housing 110 to open or close the air outlet 112. Specifically, the driving mechanism is generally selected to be a motor.

[0064] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
