[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basics of the utility model in a schematic manner, so it only shows the structure related to the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] Please refer to Figure 1 The utility model provides a mobile air conditioner 1, comprising a shell 10 and a fan 20 arranged inside the shell 10.

[0028] The housing 10 is a rectangular parallelepiped structure, including a top housing 11 disposed at the top of the mobile air conditioner 1 , a rear housing 12 at the rear end of the mobile air conditioner 1 , and a front housing 13 at the front end of the mobile air conditioner 1 .

[0029] A front shell assembly 131 is disposed on the front shell 13 . The front shell assembly 131 includes a transverse air guide strip 1311 and an air outlet grille 1312 disposed at the rear end of the transverse air guide strip 1311 .

[0030] There are four transverse air guide strips 1311 arranged in a row in front of the front shell assembly 131. The transverse air guide strips 1311 are rotated up and down to make the mobile air conditioner 1 swing air up and down.

[0031] Please refer to Figure 2 , 3 The fan 20 is generally cylindrical in structure, and includes a volute 21 and a wind wheel 23 disposed in the volute 21 .

[0032] The volute 21 is roughly in the shape of a cylindrical hollow shell, including an upper volute 211 and a lower volute 212. The upper volute 211 is provided with a circular first mounting hole 2111, and a dovetail-shaped limiting groove 2112 is provided at the top of the first mounting hole 2111. The lower volute 212 is provided with a circular second mounting hole 2121.

[0033] Please refer to Figure 4-8A vertical air guide strip 22 is also provided in the volute 21. The vertical air guide strip 22 is roughly in the shape of an "I"-shaped long strip with protrusions at both ends, including a rotating shaft 221, a guide plate 222 arranged on the side of the rotating shaft 221, an upper end is recessed toward the center of the rotating shaft 221 to form a first rotating portion 223, a limiting protrusion 225 is provided on the outer surface of the first rotating portion 223, and a lower end is recessed toward the center to form a second rotating portion 224, and the second rotating portion 224 is engaged with the second mounting hole 2121 on the lower volute 212.

[0034] Please refer to Figure 9-11 The rotation angles of the vertical air guide strip 22 include but are not limited to 0°, 30°, and 60°. When the vertical air guide strip 22 is at different angles, the mobile air conditioner 1 is controlled to guide air to different angles to the left and right.

[0035] The limiting protrusion 225 is substantially in the shape of a block with a trapezoidal bottom surface, and is engaged with the limiting groove 2112 during installation.

[0036] The guide plate 222 is generally in the shape of a letter "I" with a protrusion in the middle. The protrusion in the middle can reduce the friction resistance between the wind flow and the guide plate 222 .

[0037] A motor 13 is provided at the upper end of the upper volute 111. The motor 13 is roughly in a cylindrical block structure. During installation, the lower end of the motor 1 is fixedly connected to the first rotating part 233. The motor 13 drives the rotating shaft 221 to rotate, and the guide plate 222 rotates with the rotating shaft 221 to realize the left and right swing of the vertical air guide strip 22.

[0038] The mobile air conditioner 1 further includes an evaporator 40 , which is disposed at the front end of the rear housing 12 and is used for cooling the mobile air conditioner 1 .

[0039] The working process of the mobile air conditioner 1 of the utility model is described below with reference to the accompanying drawings:

[0040] The vertical air guide strip 22 is fixed inside the volute 21 by passing the first rotating part 123 through the first mounting hole 1112 on the upper volute 111 and fixedly connected to the motor 13 , the limiting protrusion 225 is engaged in the limiting groove 2112 , and the second rotating part 124 is fixedly connected to the second mounting hole 1121 .

[0041] When the wind wheel 23 rotates, the evaporator 40 cools the airflow, and the airflow first passes through the vertical air guide strip 22, and then passes through the horizontal air guide strip 1311 at the front end of the front shell assembly 131 to blow out of the mobile air conditioner 1. In manual control, the vertical air guide strip 22 is manually rotated to control the left and right wind swing, and in automatic control, the motor 30 rotates to drive the vertical air guide strip 22 to swing left and right.

[0042] The wind flow on the left side of the fan 20 is relatively small, and the vertical air guide strip 12 mainly guides the wind on the right side of the fan 20 .

[0043] Therefore, the mobile air conditioner 1 of the utility model has at least the following beneficial effects:

[0044] The vertical air guide strip 22 is arranged inside the volute 21, does not occupy the space of the front shell assembly 131, and is not easily damaged by touch. The vertical air guide strip 22 is driven by the motor 13 to achieve automatic control and easy operation. The raised structure in the middle of the guide plate 222 can reduce the friction resistance between the wind flow and the guide plate 222, so that the mobile air conditioner 1 can output soft and comfortable air.
