[0017] In order to clearly illustrate the scheme in the utility model, preferred embodiments are given below and described in detail with reference to the accompanying drawings. The following description is essentially only exemplary and is not intended to limit the application or use of the present disclosure. It should be understood that in all the drawings, corresponding reference numerals represent the same or corresponding parts and features.

[0018] like Figures 1 to 5As shown, the utility model provides an improved wall-mounted air compressor, comprising a housing 1, a main unit 2 installed in the housing 1, and a tube reel device 3, wherein the main unit 1 is connected to the tube reel device 3, and the tube reel device 3 comprises a rotating disk 31 and an air pipe 32 wound on the rotating disk 31, a vent shaft 4 is installed in the housing 1, the rotating disk 31 is sleeved on the vent shaft 4, an air passage 41 is formed in the center of the vent shaft 4, a straight plug connector 42 is installed at one end of the vent shaft 4, the straight plug connector 42 is connected to a bent and coiled heat dissipation pipe 11, and the heat dissipation pipe 11 is connected to the air outlet of the main unit 1. The utility model is a wall-mounted air compressor with a reel function, which is installed on a wall or other similar external structures, and the air pipe 32 can be pulled out or retracted from the rotating disk 31 for easy use. The main improvement of the utility model is that one end of the ventilation shaft 4 adopts a straight plug connection structure, that is, a connecting through hole 45 is formed on one end of the ventilation shaft 4, the connecting through hole 45 is communicated with the airway 41, and the connecting through hole 45 is installed with the straight plug connector 42. Therefore, the ventilation shaft 4 in the utility model is simple to process and easy to install.
