[0095] The compressor device 120 has a compressor axis 122, wherein the compressor axis 122 is predefined along a direction 123 in which air is compressed by the compressor device 120. As soon as the electric motor 140 is supplied with electrical power, a driveshaft 141 of the electric motor 140 is set in rotation and in the process forms a rotation axis 142. The rotation axis 142 of the electric motor 140 here represents an electric motor axis 144.

[0096] The gearbox 160 disposes the compressor device 120 and the electric motor 140 at an angle to one another. Here, the compressor axis 122 and the electric motor axis 144 form an angle 400 in the region between 10° and 80°. By using the gearbox 160, the electric motor 140 is mechanically connected to the compressor device 120. As a result, the electric motor 140 drives the compressor device 120. In the process, the driveshaft 141 engages at least in part in the gearbox 160.

[0097] The gearbox 160 is embodied here as a bevel gear 162. In this respect, the gearbox 160 comprises a gear wheel 164. The gear wheel 164 is rotatably mounted in a gearbox housing 166. The gearbox housing 166 is configured for connecting the electric motor 140 to the compressor device 120. Here, the driveshaft 141 engages in a form-fitting manner in the gear wheel 164.

In this embodiment, the receptacle 165 of the gear wheel 164 is formed as an opening with a thread. The compressor fastening element 125 is formed as a screw with a nut here. Here, the receptacle 165 of the gear wheel 164 and the gearbox axis 163 have a mutual spacing; see also FIG. 3. The gearbox 160 thus converts the rotation of the gear wheel 164 into a substantially axial movement of the compressor con rod 124 along the compressor axis 122.

[0099] The compressor device 120 furthermore comprises a compressor housing 126. By using the first connection element 168, the compressor housing 126 is connected to the gearbox 160.

The compressor valve 129 closes the compressor outlet 128 substantially in such a manner that the compressed air escapes at a predefined air pressure. The compressed air flows to the compressor connection element 127 by way of the compressor outlet 128 and the compressor valve 129.

[0101] Here, the compressor piston 131 is connected to the compressor con rod 124 at least in a form-fitting manner. Here, the compressor con rod 124 is mounted so as to be pivotable in the compressor piston 131. Moreover, the compressor piston 131 is mounted so as to be movable in the compressor cylinder 130. The compressor piston 131 comprises a compressor seal 133, wherein the compressor seal 133 is disposed so as to at least in part encircle the compressor piston 131. The compressor seal 133 is formed in the manner of a lip. The compressor seal 133 is substantially impermeable to air in a first operating direction of the compressor piston 131, and substantially permeable to air in a second operating direction of the compressor piston 131. As a result thereof, in the first operating direction of the compressor piston 131 the air in the compressor cylinder 130 can be compressed, and in the second operating direction of the compressor cylinder 130 air can flow into the compressor cylinder 130. In this embodiment, the first operating direction of the compressor piston 131 is along the direction 123 in which air is compressed, whereas the second operating direction of the compressor piston 131 is counter to the direction 123 in which air is compressed.

[0102] Therefore, the compressor device 120 has the compressor housing 126, the compressor cylinder 130, the compressor piston 131, the compressor seal 133, the compressor con rod 124 and the compressor valve 129.

[0103] The first connection element 168 is additionally provided for guiding the compressor piston 131 along the compressor axis 122 when the electric motor 140 drives the gear wheel 164. To this end, the first connection element 168 comprises a piston guide element 169. Here, the piston guide element 169 receives the compressor piston 131 at least in a form-fitting manner and guides the compressor piston 131 along the compressor axis 122. In this embodiment, the piston guide element 169 is configured as an opening in the manner of a hollow cylinder.

The fastening means 302 here serves for fastening the hose to the elongate housing 110. Here, in the first embodiment 304 the fastening means 302 is formed as a C-shaped snap-fit receptacle.

[0119] FIG. 6a illustrates a second embodiment 306 of the hose fastening of the air compression device 100. Here, the air compression hose 300 has a hook 307 for fastening the hose. Moreover, a hook receptacle 308 for the hook 307 of the air compression hose 300 is formed between the housing lower shell 502 and the second housing lateral shell 506. The hook receptacle 308 can receive the hook 307 in a form-fitting manner.

[0120] FIG. 6b shows a third embodiment 310 of the hose fastening. Here, the air compression hose 300 has a rail 311 in the manner of a prism with a triangular base area. The housing lower shell 502 here has a receptacle 312 in the manner of a prism with a triangular base area, such that the receptacle 312 can receive the rail 311 at least in a form-fitting manner.

[0121] FIG. 6c shows a fourth embodiment 314 of the hose fastening. In the fourth embodiment 314, the air compression hose 300 has a rail 315 with a quadrangular base area. The housing lower shell 502 here comprises a receptacle 316 which is formed as a prism with a substantially quadrangular base area.

[0122] FIG. 6d shows a fifth embodiment 318 of the hose fastening. Here, the second housing lateral shell 506 has a first C-shaped snap-fit receptacle 319 and a second C-shaped snap-fit receptacle 320. The air compression hose 300 can be connected to the second housing lateral shell 506 in a form-fitting manner by means of the first C-shaped snap-fit receptacle 319 and the second C-shaped snap-fit receptacle 320.

[0123] FIG. 6e illustrates a sixth embodiment 320 of the hose fastening. Here, the air compression hose 300 has a magnetic head 323. Furthermore, the second housing lateral shell 506 comprises a C-shaped snap-fit receptacle 324 and a magnetic receptacle 325. The air compression hose 300 can be connected at least in a form-fitting manner to the second lateral housing shell 506 by way of the C-shaped snap-fit receptacle 324. Additionally, the air compression hose 300 can be connected to the second housing shell 506 by way of a magnetic connection between the magnetic head 323 and the magnetic receptacle 325.

[0124] FIG. 7 shows a view from above of the air compression device 100 having the storage device 112. The elongate housing 110 comprises the storage device 112. Here, the storage device 112 is formed as a storage compartment in the housing upper shell 500. The storage device 112 can receive accessories for the air compression device 100, adapters 340, 341, 342, such that the user can insert the adapters 340, 341, 342 to suit the specific situation. The storage device 112 receives the adapters 340, 341, 342 at least in a form-fitting manner. The storage device 112 is closed by a storage lid, which is not illustrated in more detail.
