Detailed Description

In order to make it possible to understand the other features and advantages of the present utility model and the effects achieved by the features and advantages more easily, the present utility model will be described in detail below with reference to the accompanying drawings:

referring to fig. 1 and 2, the present utility model provides a fan structure, which includes: at least one connecting piece 14, a plurality of shells 1 and a plurality of bases 2.

The multiple shells 1, each shell 1 is internally provided with a runner 11, the shell 1 is provided with a plate 15, the plate 15 is provided with a slope 151, the slope 151 is provided with a filter 13, the surface of the shell 1 is provided with at least one air outlet 12, and the at least one air outlet 12 is communicated with the runner 11. The filter 13 may be a screen. For example, the plurality of housings 1 may include a first housing 111 and a second housing 112.

At least one connecting piece 14, the connecting piece 14 is arranged between the shell 1 and the shell 1, the connecting piece 14 can enable the shell 1 to rotate, so that the included angle between the shells 1 is increased or decreased; the connecting piece 14 may be a hinge or a rotating shaft, and the first housing 111 and the second housing 112 are connected by the connecting piece 14.

The bases 2 are respectively connected to the shells 1, at least one air inlet 21 is formed on the surface of each base 2, an air suction device 22 is arranged in each base 2, and the air suction devices 22 are communicated with the flow channels 11 of the shells 1. Referring to fig. 3, the air suction device 22 may include a motor 221 and a fan blade 222, wherein the fan blade 222 is connected to the motor 221. In addition, the base 2 also has a supporting function to stabilize the plurality of housings 1 without affecting the rotation of the plurality of housings 1.

With continued reference to fig. 1 and 2, a connecting member 3 is disposed between the housing 1 and the base 2, a pipe 31 is disposed in the connecting member 3, the pipe 31 has a first opening 311 and a second opening 312, the first opening 311 is communicated with the flow channel 11 of the housing 1, the second opening 312 is communicated with the base 2 (the base 2 may be provided with an opening communicating with the second opening 312), and the aperture of the first opening 311 is smaller than that of the second opening 312.

The principle of operation of the present utility model is described below: air can enter the inside of the base 2 through the air inlet hole 21 on the surface of the base 2, the motor 221 in the base 2 can provide power to drive the fan blade 222 to rotate, the fan blade 222 sucks the air entering the inside of the base 2 to the second opening 312 of the connecting piece 3, the air passes through the pipeline 31 of the connecting piece 3 to the first opening 311, the air pressure is increased due to the fact that the aperture of the first opening 311 is smaller than that of the second opening 312, the air is converged, the air can flow towards the flow channel 11 of the shell 1, the air is blown out of the air outlet hole 12 through the flow channel 11, and the blown air can rebound to a specific direction after encountering the plate 15. The filter 13 is a filter screen, and can filter the air flow blown out from the air outlet 12 to remove suspended matters in the air. The filter 13 is removable and replaceable, because the filter 13 filters for a long period of time, and can absorb many suspended substances, and even clog the filter 13, thereby affecting the cleaning effect. Thus, both the first housing 111 and the second housing 112 can provide clean and filtered air, and the first housing 111 can be rotated away from the second housing 112 (or the second housing 112 can be rotated away from the first housing 111), so that the included angle between the first housing 111 and the second housing 112 becomes larger (as shown in fig. 4), and the range of the blown air flow increases. Alternatively, the first housing 111 may be rotated to approach the second housing 112 (or the second housing 112 may be rotated to approach the first housing 111), so that the angle between the first housing 111 and the second housing 112 is reduced (as shown in fig. 5), and the range of the blown air flow is reduced. The first housing 111 may also be rotated, and the first housing 111 may be oriented in a specific direction, such that the first housing 111 blows air in the specific direction. The second housing 112 is also rotated, and the second housing 112 faces another specific direction, so that the second housing 112 blows out the air flow toward the other specific direction.

Therefore, the air suction device 22 sucks air into the flow channel 11 of the housing 1 through the air inlet 21, and the air passes through the flow channel 11 to the air outlet 12, so that the air outlet 12 blows out air flow, the blown air flow can rebound to a specific direction after encountering the plate 15, the filter 13 can remove suspended matters in the air, and the wind direction can be changed by rotating the plurality of housings 1.

Compared with the prior art, the utility model has the following advantages:

1. the plurality of housings 1 can provide a larger air flow, and the conventional art has only one housing, so that the air flow is smaller.

2. The range of the blown air flow can be adjusted, and by rotating the plurality of shells 1, the included angle between the plurality of shells 1 is adjusted, so that the range of the blown air flow is reduced or increased.

3. The housing 1 is rotated in a specific direction, and the housing 1 is caused to blow out an air flow in the specific direction.

4. The filter 13 can be replaced by a user to effectively filter suspended matters such as pollen, dust, fibers and the like in the air.

The above description is illustrative of the utility model and is not to be construed as limiting, and it will be understood by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the utility model as defined in the appended claims.
