Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan for a floor scrubber with a sealing structure. Background Art

[0002] As people's lives become increasingly intelligent, household floor scrubbers are becoming more and more common, which can quickly and efficiently complete floor cleaning work. Floor scrubbers use electric fans to drive air flow to ensure that the floor is dry and clean.

[0003] At present, the sealing effect of the shell structure of the electric blower is poor. When the floor scrubber is working, water stains and water vapor will penetrate into the motor, causing the motor circuit to burn out and the bearings to rust and jam, thereby shortening the service life of the floor scrubber.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments. Example

[0019] like Figure 1-3 As shown, a floor scrubber fan with a sealing structure includes an upper shell 1 and a lower shell 3, wherein a stator 8 and a rotor 9 are arranged in the upper shell 1 and the lower shell 3, an upper end cover assembly 6 is connected to the upper end of the upper shell 1, and an air hood 5 is connected to the lower end of the lower shell 3, the upper shell 1 and the lower shell 3 are filled and connected by a sealing gasket 2, a control panel 7 is arranged in the upper end cover assembly 6, a lower end cover 4 is arranged between the lower shell 3 and the air hood 5, an impeller 11 is arranged in the air hood 5, a glue storage tank 12 is arranged between the lower shell 3 and the air hood 5, and the lower shell 3 and the rotor 9 are connected by an oil seal 10.

[0020] In embodiment one, the upper shell 1, the stator 8 and the lower shell 3 are connected by screw locking. The upper shell 1 and the lower shell 3 are both made of heat-conducting materials. The lower shell 3 contains a motor housing and a fan guide vane structure. The guide vane structure and the heat-conducting materials of the upper shell 1 and the lower shell 3 cooperate to dissipate heat in the motor.

[0021] In the second embodiment, glue is filled in the glue storage tank 12, and the lower shell 3 and the wind hood 5 are connected by glue. A transition fit is adopted between the lower shell 3 and the wind hood 5, and glue is used for bonding to ensure the assembly strength while playing a sealing role. The structural design of the glue storage tank 12 can ensure the glue filling amount and ensure the sealing effect.

[0022] In the third embodiment, a polytetrafluoroethylene gasket 14 is provided at the upper end of the oil seal 10, and the oil seal 10 is located on the same axis as the rotor 9 through the polytetrafluoroethylene gasket 14. An oil seal rubber 13 is provided at the lower end of the lower end cover 4. The lower shell 3 and the rotor 9 are press-fitted with the oil seal 10 in cooperation with the lower end cover 4 to achieve a sealing effect. The oil seal 10 is concentrically positioned by the polytetrafluoroethylene gasket 14 to ensure assembly accuracy. The oil seal rubber 13 is sleeved on the rotor 9. The lower shell 3 and the lower end cover 4 are sealed and connected with the oil seal 10 through the oil seal rubber 13.
