In other embodiments, the connecting portion 231 may be made of a material having elastic deformability, and the protecting portion 232 may be made of other materials having sealing effect.

Referring to fig. 4, 6 and 9, in an embodiment, the connecting portion 231 has a limiting protrusion 233, and the limiting protrusion 233 is disposed inside the second assembly hole 214 and can abut against the inner wall of the housing 21, as shown in fig. 6. Fig. 9 shows the positional relationship between the connecting portion 231 and the limit projection 233 and the housing 21 when the guard portion 232 is fitted in the first fitting hole 211. When the protection member 23 receives an external force toward the outside of the second fitting hole 214, the limit protrusions 233 of the connection portion 231 can abut against the inner sidewall 212 of the inside of the housing 21 to limit the entire connection portion 231 from being separated from the second fitting hole 214, so that the protection member 23 is not easily separated from the housing 21.

Referring to fig. 6, 7 and 10, in one embodiment, the protection member 23 further includes a first blocking portion 234 and a second blocking portion 235 connected to each other, and the connecting portion 231 is connected to the second blocking portion 235. The appearance of first shutoff portion 234 and the shape adaptation of first pilot hole 211, first shutoff portion 234 can assemble in first pilot hole 211, and the outer wall of first shutoff portion 234 can hug closely with the inner wall of first pilot hole 211 to make the outside impurity be difficult for entering electrical equipment inside from first pilot hole 211 promptly. The cross-sectional area of the second blocking portion 235 is larger than that of the first blocking portion 234, and the cross-section refers to a section parallel to the outer side wall 213 of the housing 21. When the first blocking portion 234 is assembled in the first assembling hole 211, the outer wall of the second blocking portion 235 facing the housing 21 can abut against the outer side wall 213 of the housing 21, thereby further improving the sealing effect of the protection member 23 to the first assembling hole 211.

It will be appreciated that the number of guards 23 may be provided as desired. For example, in one embodiment, two connection portions 231 are provided, two second fitting holes 214 are also provided, and two connection portions 231 are in one-to-one correspondence with two second fitting holes 214.

Referring to fig. 4 and 8, in an embodiment, the winding portion 221 is provided with a avoiding groove 2215, the winding portion 221 is avoided from the connecting portion 231 through the avoiding groove 2215, and when the bobbin 22 is mounted in the first mounting hole 211, a part of the connecting portion 231 is accommodated in the avoiding groove 2215. For example, the avoidance groove 2215 is disposed on a side of the winding portion 221 near the buckle 223, and when the bobbin 22 is assembled in the first assembly hole 211, a portion of the connection portion 231 is located in the avoidance groove 2215, so that the protection portion 232 is attached to the winding portion 221, and the power cord 12 is wound around the protection portion 232 and the outer periphery of the winding portion 221.

In an embodiment, the winding mechanism 200 further includes a rotating shaft (not shown) that is disposed through the housing 21 and the protecting portion 232, and the protecting portion 232 can rotate around the rotating shaft, so that the protecting portion 232 can be switched between a state of blocking the first assembly hole 211 and a state of separating from the first assembly hole 211.

The winding mechanism 200 of the present utility model is applied to the mobile air conditioner 100, when the power cord 12 needs to be stored, the shielding member 23 leaves the first assembly hole 211, the bobbin 22 is mounted on the first assembly hole 211, and the shielding portion 232 of the shielding member 23 is rotated to be attached to the winding portion 221 of the bobbin 22, at this time, the power cord 12 can be wound around the shielding portion 232 and the outer periphery of the winding portion 221, thereby restricting the movement of the shielding member 23 and reducing the adverse effect of the shielding member 23 during the winding process. When the power cord 12 is in a use state, that is, when the winding frame 22 is not needed, the winding frame 22 can be detached from the first assembly hole 211, and then the protecting part 232 of the protecting piece 23 is assembled in the first assembly hole 211 to block the first assembly hole 211, so that the situation that moisture, dust and other impurities enter the mobile air conditioner 100 from the first assembly hole 211 is reduced, the sealing performance of the mobile air conditioner 100 is improved, and meanwhile, the situation that the winding frame 22 hooks people or other foreign objects to cause the winding frame 22 or the whole mobile air conditioner 100 to topple over is avoided.

Further, other variations within the spirit of the present utility model will occur to those skilled in the art, and it is intended, of course, that such variations be included within the scope of the present utility model as disclosed herein.
