Embodiment 1

[0022] see Figures 1 to 4 , in the embodiment of the present invention, a fan that can be opened and closed includes a casing 1, a motor 2 and an opening and closing mechanism; the motor 2 is fixed on the inner side of the casing 1 through a motor seat, and a fan is fixed on the output shaft of the motor 2 For the blade 10, one end of the casing 1 is open, and the other end is arranged in an arc-shaped surface. The arc-shaped surface of the casing 1 is provided with a plurality of through holes 3 for air entry. A filter screen 4 is installed on the curved surface. The filter screen 4 can effectively ensure that dust enters the casing 1 and affects the use effect. The open end of the casing 1 is fixed with an opening and closing mechanism 11. A fixed plate 112 and a plurality of baffles 117 rotatably mounted on the fixed plate 112, the fixed plate 112 is provided with a chute 113, a slider 114 is slidably connected in the chute 113, and the outer end of the slider 114 passes t...

Embodiment 2

[0026] Fans generally generate noise during operation, so this embodiment is optimized. Specifically, sound-absorbing cotton (not shown in the figure) is installed on the inner wall of the housing 1, and the installation method is not limited.

Abstract

The invention discloses a fan capable of being opened and closed. The fan comprises a shell, a motor and an opening and closing mechanism. The motor is fixed to the inner side of the shell through a motor base. Fan blades are fixed to an output shaft of the motor. One end of the shell is open, and the other end of the shell is arranged in an arc-shaped surface mode. A plurality of through holes used for air entering are formed in the arc-shaped surface of the shell. A filter screen is arranged on the position, located on the inner side of the shell, of the arc-shaped surface. An opening end ofthe shell is fixedly provided with the opening and closing mechanism and comprises a rotating ring, a fixing plate and a plurality of baffles rotationally arranged on the fixing plate. The fan is novel in design. A sliding block is driven to slide in a sliding groove by rotating a rotating ring. When the sliding block slides, opening and closing of the baffles are realized through actions of a first connecting rod and a second connecting rod, the baffles are closed during no use periods, dust can be effectively prevented from entering the shell and affecting the service life of the fan and next-time use, and the direction of air can be changed through a partition plate and a movable plate.

Description

technical field [0001] The invention relates to a fan, in particular to a fan that can be opened and closed. Background technique [0002] The fan is a machine that relies on the input mechanical energy to increase the gas pressure and discharge the gas. It is a driven fluid machine. Fan is the habitual abbreviation for gas compression and gas conveying machinery in China. Generally speaking, fans include ventilators, blowers, and wind generators. [0003] Fans are widely used in ventilation, dust removal and cooling in factories, mines, tunnels, cooling towers, vehicles, ships and buildings, ventilation and induced draft in boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Drying and selection of grain, air source of wind tunnel and inflation and propulsion of hovercraft, etc. [0004] Generally, it is placed directly after the fan is used, and the dust will fall into the interior of the fan, thus affecting t...
