In specific implementation, the water guide member 6 can extend out of the shell 1 to be directly connected with external water; or can be directly connected with the water storage barrel, and the water in the water storage barrel is led to the centrifugal piece 5 through the water guide piece 6; or may be provided below the humidifying cotton 7 to collect water overflowing from the humidifying cotton 7 and then lead to the centrifugal member 5. For example, the water guiding member 6 in fig. 1 is disposed below the humidifying cotton 7 to receive the water overflowing from the humidifying cotton 7; the water guide 6 in fig. 2 is arranged above the humidifying cotton 7, and the water in the water storage tank 2 is directly led into the water guide 6. The water guide 6 is a structure for guiding the water to flow along a certain path, and the specific structure is easily designed by those skilled in the art.

There are two main improvements of the present invention.

First, the humidification system is qualitatively changed by the cooperation of the fan unit 3 and the humidification cotton 7. The traditional humidifier is a foggy humidifier, mainly uses ultrasonic waves and other means to make water into water mist to freely escape into the air, and has the problems in the background art; and this application is for there being not fog humidification, mainly utilizes the cooperation of fan unit 3 with humidification cotton 7, and fan unit 3 produces the air current for the air current passes through humidification cotton 7, thereby to the air humidification, and the air after the humidification blows out and accomplishes the humidification function. Compared with water mist, the humidifying air has small diffusion resistance, and can be fully diffused in a space environment by being driven by the fan, so that the aims of mist-free humidifying and whole-house humidifying are fulfilled.

Secondly, the centrifugal piece 5, the water guide piece 6 and the water receiving barrel 4 are additionally arranged in the humidifier, and the three components are combined and installed in an airflow path, so that the airflow passes through a water mist area on the original path, the humidification quantity can be increased, and the humidification effect of the humidifier is improved. In fig. 1 and 2, the combination is integrated with other components to be arranged, for example, in fig. 1, the water receiving barrel 4 is used for receiving not only centrifugal water of the centrifugal piece 5 but also water separated out from the humidifying cotton 7, and the water guide piece 6 is also matched with the humidifying cotton 7; for example, in fig. 2, the water receiving barrel 4 is composed of a lower water barrel and an upper water retaining cover, and is used for simultaneously receiving water of the centrifugal piece 5 and the humidifying cotton 7, and the water guide piece 6 is directly connected with the water storage tank 2 to supply water to the centrifugal piece 5.

The humidifier of this embodiment adds water receiving bucket 4, centrifuge 5 and water guide 6, and centrifuge 5 throws out water through centrifugal force and forms water smoke, because centrifuge 5 sets up in the route that the air current passes through, when the air current was regional through this water smoke, can carry more water yield to improve the humidification effect of humidifier.

Preferably, the water guide 6 is located above the centrifuge 5. The water in the water guide 6 directly flows into the centrifugal piece 5 by gravity, so that the structure is simpler and the performance is reliable. Of course, in other embodiments, the water guide 6 may be located below the centrifugal member 5, and the water in the water guide 6 may be pumped to the centrifugal member 5 by another structure such as a water pump.

Preferably, the water guide 6 is adapted to guide the water precipitated from the humidifying cotton 7 to fall onto the centrifugal member 5. The water separated out from the humidifying cotton 7 is utilized for centrifugal humidification, so that water resources are saved, and the device is more environment-friendly; and, the structural design is also simpler.

When the centrifugal water sprayer is used, water flows into the outer surface of the centrifugal piece 5 through the water guide piece 6, and is thrown out to form water mist through the centrifugal force action of the centrifugal piece 5 and the matching of the spiral teeth 521.

Further, the fan unit 3 is located above the centrifugal piece 5, and the rotating shaft of the centrifugal piece 5 is coaxially and fixedly connected with the rotating shaft of the fan unit 3.
