In addition, the mobile air conditioner 100 further includes a moving structure in order to implement the movement thereof. The mobile air conditioner 100 can be moved by means of its moving structure to change the place of placement. The mobile air conditioner 100 may specifically be a portable mobile air conditioner 100, and further includes a battery 15. Thus, the mobile air conditioner 100 can operate independently without an external power source.

Further, the moving structure is a handle 16 arranged on the housing 11. The user can lift the mobile air conditioner 100 through the handle 16 to shift its position. It will be appreciated that in other embodiments, the moving structure may be a roller or the like disposed at the bottom of the housing 11, which is not particularly limited herein.

In some embodiments, the mobile air conditioner 100 includes an air outlet assembly 20. It will be appreciated that the air outlet assembly 20 forms an air outlet in the housing 11 of the mobile air conditioner 100 such that the mobile air conditioner 100 is blown outwardly through the air outlet assembly 20.

The supply air of the mobile air conditioner 100 may be driven by the evaporation fan 12. The evaporation fan 12 comprises an air supply volute 121, the air supply volute 121 is formed by connecting a volute body 1211 and a volute cover 1212 through an air channel fixing screw 1213, an air channel F is formed in the air supply volute, and an air outlet air channel port 1214 is formed at the tail end of the air channel F. The air outlet assembly 20 is connected to an air outlet air duct port 1214, and the evaporation fan 12 forms an air flow in the air duct F of the air supply volute 121, and supplies air from the air outlet air duct port 1214 to the outside through the air outlet assembly 20.

In addition, the evaporating fan 12 may further include a motor 122, a wire pressing plate 123, a fan blade 124, a fan blade fixing nut 125, etc. disposed in the air channel F of the air supply volute 121.

Referring to fig. 5, the present application further provides an air outlet assembly 20, which includes a fixing structure 22, a flow guiding grille 24 and a spherical hinge structure 26. The fixed structure 22 is used to connect with the outlet air duct port 1214 of the mobile air conditioner 100. The diversion grating 24 is movably connected with the fixed structure 22 through a spherical hinge structure 26.

The air guide grille 24 is a grille structure which can allow air flow to pass through and can generate guiding effect on the passing air flow. When the air outlet assembly 20 is installed and used, the fixing structure 22 is fixedly connected to the air outlet channel 1214 of the mobile air conditioner 100. The air-guiding grille 24 is connected to the fixing structure 22 by a spherical hinge structure 26 and is located on the flow path of the air flow of the air outlet port 1214.

The air outlet assembly 20 has a grill 24 for directing the flow of air therethrough to form an air supply. Since the guide grating 24 is connected with the fixing structure 22 through the spherical hinge structure 26, the guide grating 24 can rotate at multiple angles through the spherical hinge structure 26, and air supply at different angles can be formed under the guidance of the guide grating 24 at different angles through the guide grating 24. Thus, the mobile air conditioner 100 is also capable of achieving multi-angle air supply adjustment through the air outlet assembly 20.

Further, the spherical hinge structure 26 includes a spherical hinge head 262 and a spherical hinge pair 264, and the spherical hinge head 262 and the spherical hinge pair 264 form a movable fit, i.e. the spherical hinge head 262 can rotate in the spherical hinge pair 264. One of the spherical hinge head 262 and the spherical hinge pair 264 is connected with the guide grid 24 to jointly form a rotor assembly, and the other is connected with the fixed structure 22 to jointly form a stator assembly.

Specifically, the spherical hinge head 262 and the spherical hinge pair 264 are in interference fit, so that the rotor assembly and the stator assembly can maintain an angle therebetween when no other external force is driven.

Therefore, the rotor assembly can also rotate at multiple angles relative to the stator assembly through the movable fit of the spherical hinge head 262 and the spherical hinge pair 264. Accordingly, rotation of the rotor assembly also effects rotation of the air-guide grille 24.

Referring to fig. 6 and fig. 7, in some embodiments, the fixing structure 22 includes a protection grille 222, and the protection grille 222 is covered on the air outlet 1214.

The protective grille 222 covers the outlet air duct 1214, which can prevent a user, especially a child, from extending his/her hand from the outlet air duct 1214 into the evaporation fan 12, thereby reducing the risk of injury caused by the fan blades 124.

In some embodiments, the outlet air duct port 1214 is configured with a positioning slot 1216, and the securing structure 22 is positioned in connection with the outlet air duct port 1214 by the positioning slot 1216.

Specifically, the protective grill 222 is configured with a connection structure 2222 on the peripheral side thereof that mates with the positioning groove 1216, and is positionally connected within the positioning groove 1216 by a grill fixing screw 2224.

Thus, the fixing structure 22 can be accurately positioned and mounted, and the spherical hinge structure 26 and the guide grating 24 can be mounted on the basis.

In some embodiments, the fixing structure 22 includes an outer frame 28, and the outer frame 28 is engaged with the air outlet port 1214 and located on the outer peripheral side of the air guiding grille 24.

It will be appreciated that the outer frame 28 is enclosed around the periphery of the air-guiding grille 24, but does not interfere with the air-out and normal rotation of the air-guiding grille 24.

The outer frame 28 can protect the guide grating 24 and reduce interference of the outside on the movement of the guide grating 24.

Specifically, the outer frame 28 is configured with a claw 282, and the air outlet port 1214 is configured with a clamping groove 1215 matched with the claw 282. The outer frame 28 is clamped into the clamping groove 1215 through the clamping claw 282 and is connected to the air outlet duct port 1214.

In some embodiments, the fixed structure 22 includes a ball sub-mount 224, the ball sub-mount 224 being coupled to an outlet air duct port 1214 of the mobile air conditioner 100. The ball hinge pair 264 is mounted on the ball hinge bracket 224, and a receiving chamber R is formed in the ball hinge pair 264. The spherical hinge head 262 is connected with the diversion grid 24 and is clamped into the accommodating cavity R.

The ball auxiliary bracket 224 is provided with at least two support arms, and the support arms can be connected with the locating groove 1216 by screws, so that the ball auxiliary bracket 224 is connected with the air outlet duct port 1214. The ball hinge pair 264 may be directly formed on the ball sub-mount 224 and mounted to the outlet air duct port 1214 along with the ball sub-mount 224.

The ball-shaped sub-bracket 224 can provide stable fixation for the ball-shaped hinge pair 264, and is connected with the ball-shaped hinge pair 264 to form a stator assembly, the ball-shaped hinge head 262 is connected with the air-guiding grille 24 to form a rotor assembly, and the rotor assembly can rotate relative to the stator assembly under the driving of external force, namely, the air-guiding grille 24 can rotate relative to the air outlet air duct port 1214.

Specifically, ball sub-mount 224 has a total of three arms. Under the connection of the three support arms, the ball auxiliary support 224 can be stably fixed, and meanwhile, the support arms cannot increase excessive wind resistance to influence the air outlet.

Further, the protection grille 222 may be disposed on a side of the ball sub-support 224 facing away from the air outlet port 1214, and the protection grille 222 and the ball sub-support 224 are fixed together by grille fixing screws 2224. The protection grille 222 is provided with an avoidance gap for the spherical hinge pair 264 and the spherical hinge head 262 to pass through to form a fit.

Further, the ball hinge pair 264 includes a ball sub body 2642 and a ball sub cover 2644, the ball sub body 2642 is disposed on the ball sub bracket 224, and the ball sub cover 2644 is disposed on the ball sub body 2642 and defines the accommodating cavity R together.

The ball cover 2644 may be attached to the ball support 224 by ball cover set screws 2662 and cover the ball body 2642.

The ball pivot pair 264 is designed to include a ball pivot body 2642 and a ball pivot cover 2644, and a receiving chamber R for receiving the ball pivot head 262 is also defined by the ball pivot body 2642 and the ball pivot cover 2644 together. The ball pair main body 2642 and the ball pair cover 2644 have low difficulty in demolding respectively, and are beneficial to reducing the production difficulty of the ball hinge pair 264.

In some embodiments, the ball pivot 262 is made of an elastic material, such as rubber.

The spherical hinge head 262 is elastically clamped into the accommodating cavity R and is pressed by the accommodating cavity R to form interference fit. When the external force overcomes the acting force between the spherical hinge head 262 and the spherical hinge pair 264, the diversion grid 24 can be driven to rotate relative to the air outlet air duct 1214 through the spherical hinge head 262.

Further, the spherical hinge structure 26 further includes a connecting member 268, wherein one end of the connecting member 268 is connected to the air guide grille 24, and the other end of the connecting member 268 protrudes radially to form a locking protrusion 2682, and is locked with the spherical hinge head 262 by the locking protrusion 2682.

The spherical hinge head 262 is connected with the flow guiding grille 24 through a connecting piece 268, and one end of the connecting piece 268 with a clamping protrusion 2682 is clamped in the spherical hinge head 262. In this way, the elastic ball joint 262 can form a stable connection with the connector 268 through the engaging protrusion 2682.
