A fan motor is disclosed. The fan motor includes a rotating shaft, a motor, a bearing, a bearing housing, a preload applying device, and a bush. The preload applying device is disposed between one axial end of the bearing and the bearing housing, and applies force to the one axial end of the bearing in an axial direction by using elastic force. The bush is coupled to an outer circumferential surface of the bearing and slidably mounted on an inner circumferential surface of the bearing housing in an axial direction. A protrusion is formed on one axial end portion of the bush, and a protrusion accommodating groove is formed on an axial inner surface of the bearing housing. Accordingly, the preload applying device can continuously apply an appropriate preload to the bearing, while the bush can suppress slipping of an outer ring of the bearing.

The present disclosure relates to an essential oil spray device, including: a box assembly comprising a liquid storage part, a liquid filling port being provided in the liquid storage part; a cover assembly, sealingly connected to the liquid storage part, the cover assembly being provided with a spray port, and the spray port being provided with an atomizing member; a plug, provided at the liquid filling port; a switch assembly, provided on the box assembly and electrically connected to the atomizing member. The present disclosure addresses the problems of the essential oil spray device in the prior art, for example, it needs to replace the essential oil bottle with a new essential oil bottle after the essential oil is used up, the use cost is high, and the essential oil bottle and housing adopt a split design, causing a complex structure and a large installation space.

A hair accessory including a liquid impermeable bag comprising a sheet gathered at one end and a band attached to the bag. A method of removing oil from hair including partitioning the hair of the user into a first section and a second section defined by a boundary path on a head of the user which divides the first and the second sections, placing the band along the boundary path, placing the second section inside the bag and washing the first section while keeping the second section dry due to the placing inside the bag. The placement of the band is approximately midway between the front and rear of the head of a user.

A hand held appliance comprising a fluid flow path extending from a fluid inlet into the appliance to a fluid outlet from the appliance, the fluid flow path being at least partially defined by a wall, a switch mechanism housed by the wall having a cooperating externally accessible actuating button and a switch cover extending within the wall and containing the switch mechanism. The switch cover may maintain a spatial location of the switch mechanism relative to the actuating button. The switch cover may encase the switch mechanism. The switch cover may isolate the switch mechanism from the fluid flow path. The switch cover may maintain a spatial location of the switch mechanism relative to the wall. The switch cover may be curved towards an upstream end to reduce disturbance to the flow of fluid within the fluid flow path.
