Embodiment Construction

[0031] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0032] see Figure 1A and as shown in Figure 1B, where Figure 1A It is a three-dimensional exploded schematic view of a preferred embodiment of the centrifugal fan of the present invention; FIG. 1B is a combined schematic view of a preferred embodiment of the centrifugal fan of the present invention. The fan device 1 includes a casing 10 , an impeller 11 and a driving device 14 . The housing 10 is composed of an upper housing 101 and a lower housing 102 . Different from the shell formed by the traditional spiral involute, the axial cross-sectional shape of the accommodating space formed by the upper shell 101 and the lower shell 102 is circular instead of the cross-sectional shape of the prior art. The upper housing 101 has an air inlet 1011 above the center, and the lower housing 102 has an air outlet 1...

Abstract

The invention provides a centrifugal fan and a dust collecting box module with the centrifugal fan. The centrifugal fan is characterized in the design of the shell, the fan shell of the invention has two characteristics, the first characteristic is that the width of the air flowing channel of the fan device is same, the second characteristic is that an axially central section line of the impellerinside the centrifugal fan divides the inner space of the fan device into two flowing channel spaces unsymmetric with each other, thereby the centrifugal fan can produce big flow capacity, big pressure differential and low noise through the two characteristics, the invention can provide a dust collecting box module by using the centrifugal fan, the centrifugal fan is used to collect the external dust through the dust collecting box structure, the effect of clean environment can be achieved.

Description

technical field [0001] The present invention relates to the structure of a centrifugal fan, in particular to a design of the fan housing in which an equidistant gas channel and an up-and-down asymmetric channel space are formed between the edge of the impeller and the fan housing, so that the centrifugal fan It has the characteristics of low noise and high flow, and then uses the centrifugal fan to form a module that can absorb and collect dust. Background technique [0002] The automatic vacuum cleaner is a fully automatic cleaning device, which is different from traditional vacuum cleaners and sweeping tools. It can complete the cleaning work in a fixed area by itself, replacing traditional manual vacuum cleaners and other cleaning tools. After setting the cleaning mode, the automatic vacuum cleaner will automatically perform the function of cleaning the floor, and can dodge indoor furniture or obstacles to complete the cleaning work. In addition, the automatic vacuum clea...
