Description

Technical Field

[0001] The present application relates to the technical field of fans, and in particular to a garden fan. Background Art

[0002] Garden fans, as a cleaning tool, can effectively blow away fallen leaves and grass clippings.

[0003] In garden fans, ducts are very important. In order to reduce the noise of the fan, silencer cotton is generally installed to solve the noise problem. For example, a garden fan proposed in announcement number CN211975528U is to split the bell mouth, then stick silencer cotton on its inner side, and finally fix it on the left cover of the duct. However, this method is relatively complicated, and since the duct and the bell mouth are connected by a touch type, this will affect the shock absorption effect between the duct and the left and right shells of the fuselage to a certain extent. Another method is to make the silencer cotton into a funnel shape, insert it into the air inlet end of the duct, and support the other end with a plastic part and clamp it on the left and right covers of the fuselage. Although this method solves the impact on the shock absorption effect of the duct, its structural strength is not ideal, and the installation process is relatively complicated. Therefore, how to simplify the installation structure while ensuring structural strength is the purpose of this application.

[0004] The above content is only used to assist in understanding the technical solution of this application, and does not mean that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, the present application provides a garden fan to solve one of the above technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a garden fan, including: a duct, a channel for gas circulation; a bell mouth, including a first bell part and a second bell part, the first bell part and the second bell part are arranged opposite to each other and installed on the duct; a silencer part, including a first silencer cotton and a second silencer cotton, the first silencer cotton and the second silencer cotton are respectively installed on the first bell part and the second bell part.

[0007] In some embodiments, a first connecting portion and a second connecting portion are disposed on the first horn portion.

[0008] In some embodiments, a third connecting portion and a fourth connecting portion are provided on the second horn portion, and the first connecting portion and the third connecting portion are connected by screws.

[0009] In some embodiments, a fifth connection portion is provided at both ends of the duct, the fifth connection portion is mounted together with the second connection portion and the fourth connection portion by screws, and the fifth connection portion is provided between the second connection portion and the fourth connection portion.

[0010] In some embodiments, the first speaker portion and the second speaker portion are respectively provided with a first connecting protrusion and a second connecting protrusion, and the duct is provided with a connecting recess that cooperates with the first connecting protrusion and the second connecting protrusion.

[0011] In some embodiments, the width of the top of the first connecting protrusion and the second connecting protrusion plus the width of the top of the connecting recess is equal to the thickness of the first sound-absorbing cotton and the second sound-absorbing cotton.

[0012] In some embodiments, the first sound-absorbing cotton and the second sound-absorbing cotton are mounted on the first horn portion and the second horn portion by any one of adhesive fixation, magnetic fixation, and mechanical fixation.

[0013] The beneficial effect of the present application is that by splitting the bell mouth into a first bell part and a second bell part, installing silencer cotton and then fixing it on the duct with screws, the duct and the bell mouth become an integrated part. This method effectively reduces the impact of the installation of the bell mouth on the shock absorption effect of the duct, and the structure is relatively simple, and the production process has been improved.
