The labels in the figure are: the air conditioner comprises a shell 1, a first air inlet 2, a second air inlet 3, an air outlet 4, a motor 5, a first impeller 6, a second impeller 7, supporting legs 8, a blocking piece 9 and a lifting handle 10.

Detailed Description

The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the utility model or equivalent substitutions of parts of technical features without departing from the spirit of the utility model are intended to be covered by the scope of the claims of the utility model.

As shown in fig. 1-4, a double-inlet double-blade blower includes a housing 1 and a control panel (not shown), wherein a first inlet 2, a second inlet 3 and an outlet 4 are respectively formed on the housing 1. The air blower is characterized in that a driving device is arranged in the shell 1, the driving device is electrically connected with the control panel and comprises a motor 5, a first impeller 6 and a second impeller 7, the motor 5 drives the first impeller 6 and the second impeller 7 to rotate, the first impeller 6 faces the first air inlet 2, the second impeller 7 faces the second air inlet 3, air generated by the first impeller 6 and the second impeller 7 flows to the air outlet 4 together, the air quantity of the air blower is increased, meanwhile, the air blower can be kept balanced, and the air blower is prevented from being accidentally toppled. Through setting up first impeller 6 with second impeller 7 provides sufficient power for the air-blower operation, has solved current air-blower wind pressure undersize, the amount of wind is not enough, the big scheduling problem of import loss of pressure, and this fan is in the in-service behavior in-process, if the emergence is turned on one of them air intake of perhaps having blockked up, and another air intake can normal use in addition, guarantees that this fan can normal operating. In addition, the housing 1 may be split and divided into a left housing and a right housing, the left housing and the right housing are assembled to form an installation cavity, the driving device is installed in the installation cavity, and the first air inlet 2 and the second air inlet 3 are respectively located on the left housing and the right housing, as will be understood by those skilled in the art. In addition, first air intake 2 with be equipped with the waterproof layer on the second air intake 3, can play waterproof effect, reduce and enter into because of rain or during rainstorm rainwater in the casing 1, prevent that inside electronic components is impaired.

Further, the first impeller 6 and the second impeller 7 may be single blades or double-layer blades, and the double-layer blades can enhance the air volume and dissipate heat of the motor 5.
