[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] like Figure 1 , Figure 2 As shown, a tower fan with an improved bearing includes a front housing 1, a rear housing 2, a top control box 3, a motor 4, a cross-flow impeller 5, a silicone bearing 6, a bracket made of plastic material 7, and fasteners 8. The cross-flow fan wheel 5 has an upper half shaft 51 at the upper end and a hinge seat 52 at the lower end. The hinge seat 52 has a shaft hole with a lower opening. An annular support disc 41 is provided on the motor shaft of motor 4. The silicone bearing 6 has a longitudinal shaft hole 61; The front shell 1 and rear shell 2 are fastened together to form the housing, and the front shell 1 and rear shell 2 are detachably connected.
