In the present invention, when the water tank part 20 is not used, the upper recessed cap 27 is mounted on the upper recessed part 213, and the upper recessed part 213 and the air hose valve 22 are connected. It can be covered and protected.

Additionally, the upper recessed cap 27 may be adjacent to the upper recessed portion 213 and be subordinate to the water receiving portion 21. Specifically, it can be arranged to be detachably attached to the upper recessed part 213 while being dependent on the water receiving part 21 through a chain-shaped first dependent mediator (not shown).

The lower recessed cap 28 may cover the lower recessed portion 211 while being formed in a shape corresponding to the recessed space of the lower recessed portion 211.

The lower recessed cap 28 is mounted on the lower recessed part 211 and covers the water valve 25 when the water valve 25 formed in the lower recessed part 211 is not used. You can.

The space between the lower recess 211 and the water valve 25 is narrow, so it is easy for foreign substances introduced from the outside to stay, and if water as well as foreign substances stays and cools and freezes, the lower recess ( A crack may occur between 211) and the water valve 25, causing water to flow out.

In the present invention, when the water tank part 20 is not used, the lower recessed cap 28 is mounted on the lower recessed part 211 to cover the lower recessed part 211 and the water valve 25. You can protect it.

Additionally, the lower recessed cap 28 may be adjacent to the lower recessed portion 211 and be subordinate to the water receiving portion 21. Specifically, it can be arranged to be detachable from the lower recessed part 211 while being dependent on the water receiving part 21 through a chain-shaped second dependent mediator (not shown).

Figure 10 is a schematic diagram illustrating a portable multi-air compressor equipped with a water tank according to another embodiment of the present invention.

Referring to Figure 10, the multi air compressor according to another embodiment of the present invention is the multi air compressor (illustrated with reference to Figures 1 to 8) except for the body mounting guide portion 18 and the water mounting guide portion 215. Since it has the same configuration and effect as 1), only the mounting guide part will be described below.

The main body portion according to another embodiment of the present invention may further include a body mounting guide portion 18 that protrudes from the rear surface and is formed along the height direction.

The water receiving portion is formed to protrude from the front surface and may further include a water mounting guide portion 215 on which the main body mounting guide portion 18 is slidably mounted.

The main body part can be mounted on the water receiving part when the main body mounting guide part 18 is slidably mounted on the water mounting guide part 215 in an overturned state.

When the main body is mounted on the water receiving part 21, the outer surface is disposed on the same plane as the bottom of the water receiving part, so that it can be in close contact with the bottom surface.

When the water in the water receiving part is sprayed at a certain pressure by the air compressor part 10', the air hose part 15 of the air compressor part 10' and the water tank part 20' The air hose valve (22) must remain connected.

At this time, if the main body part and the water receiving part are located separately, if one member moves in an unexpected situation and strong tension is generated in the air hose part 15, damage or breakage of the air hose part may occur. At the same time, the connection between the air hose part and the air hose valve is weakened, and the pressure in the water receiving part drops rapidly, which may cause problems in using the shower nozzle 23.

Accordingly, the present invention solves the above-mentioned problem by making the main body part 11 subordinate to the water receiving part 21 according to the mutual installation of the main body mounting guide part 18 and the water mounting guide part 215. I was able to.

In addition, when the main body portion 11 is mounted on the water receiving portion 21, the port portion 50 is in close contact with the front surface of the water receiving portion 21 to prevent water or foreign substances from entering from the outside. This may be blocked.

The hose accommodating part 115 is arranged to face one side of the water accommodating part 21 when the main body part 11 is mounted on the water accommodating part 21, so that the air hose part 15 It can be easily installed on the air hose valve 22.

In the above, the configuration and features of the present invention have been described based on the embodiments according to the present invention, but the present invention is not limited thereto, and various changes or modifications may be made within the spirit and scope of the present invention. It is obvious to those skilled in the art, and therefore, it is stated that such changes or modifications fall within the scope of the appended patent claims.
