Description

a fan

technical field

The utility model relates to a fan, in particular to a fan with shutters.

Background technique

The air outlet of the fan is generally equipped with louvers. When the fan is started, the louvers are automatically opened, which is beneficial to the exhaust of the fan. Existing fan louvers are installed on the frame of the fan by rotating the louvers one by one through the connecting rod. The louver and the window frame are separated. One-page louvers are difficult to disassemble, the process is cumbersome, time-consuming to assemble, and very inconvenient. Sometimes a little carelessness during the disassembly process will damage the louvers, and even have to replace the louvers. For this reason, it is necessary to develop a fan structure with simple assembly to facilitate use.

Utility model content

In order to solve the technical problem that the blinds are inconvenient to disassemble, the utility model provides a reasonable technical solution as follows:

A fan includes a fan body and louvers. The fan body is composed of an outer casing, a motor located in the center of the casing, and an impeller connected to the output shaft of the motor. The louver includes a frame and a plurality of louver blades. On the frame body, the frame body is fixedly connected to the cover case, and the louvers block the air outlet of the fan body as a whole through the cooperation of the frame body and the cover case.

The louver includes a frame, a rotating shaft, a connecting rod and a plurality of louvers. The connecting rod is placed inside the vertical frame of the frame, and one end of the rotating shaft is connected to the connecting rod; The cooperation with the connecting rod and the connection of the louvers are integrated.

Preferably, the rotating shaft is Z-shaped.

Preferably, a weight is provided under the connecting rod.

Preferably, the frame body is fixedly connected to the casing by screws around it.

Beneficial effects of the utility model: when the fan of the utility model is adopted, the louvers are integrally installed on the air outlet of the fan body, which is convenient to disassemble, and the fan can be easily cleaned or maintained without removing each louver blade, which saves During working hours, the frame body is connected with the louver through the cooperation of the rotating shaft and the connecting rod as an integrated structure, which is convenient for installing the entire louver to the tuyere of the fan. The structure is simple and reasonable. In addition, the cooperation of the Z-shaped rotating shaft and the connecting rod makes multiple It can rotate at the same time, and there will be no phenomenon that individual louvers are closed and individual louvers are opened, which ensures that the fan can exhaust air smoothly.

detailed description

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:

As shown in Figure 1, a fan includes a fan body 1 and a shutter 2. The fan body 1 is composed of an outer casing, a motor located in the center of the casing, and an impeller connected to the output shaft of the motor. The shutter 2 can pass through the frame. 4 The screws all around are integrally fixed and installed on the casing of the fan body 1, and the louver 2 blocks the air outlet of the fan body 1.

As shown in Figures 2 to 3, the shutter 2 includes a frame body 4, a rotating shaft 5, a connecting rod 6 and a plurality of louver blades 3, the connecting rod 6 is placed inside the vertical frame of the frame body 4, and one end of the rotating shaft 5 is connected to the connecting rod; the other end The vertical frame passing through the frame body 4 is connected to the louver blade 3, and the frame body 4 is connected to the louver blade 3 through the cooperation of the rotating shaft 5 and the connecting rod 6 as an integral structure. Each louver blade 3 saves man-hours.

When a page of louver 3 rotates, the louver 3 drives the connecting rod 6 to move up and down through the rotating shaft 5. The rotating shaft 5 is Z-shaped, which can effectively transmit the rotation angle of each louver 3 and easily drive the connecting rod 6 to move up and down. The connecting rod 6 drives the other louvers 3 to rotate through the rotating shaft 5 , so that all the louvers 3 rotate synchronously, and the louvers 2 are opened or closed.

As shown in FIG. 4 and FIG. 5 , a weight 7 is provided under the connecting rod 6 , and the weight 7 is placed in the vertical frame of the frame body 4 . When the fan body 1 is started, the wind blows to the louvers 3 to slightly open the louvers 3 to a certain angle, and the weight 7 continues to pull down the connecting rod 6 to level the louvers 3 to fully open the louvers.

When the fan body 1 is working, the impeller rotates, and the wind blows to the louvers 2. Under the action of the wind, all the louvers 3 rotate at a certain angle, and the louvers 2 are opened to let the wind pass. Down, the shutter 2 is closed to prevent foreign matter from entering the fan and play a protective role.

The above content is a further detailed description of the utility model in conjunction with specific preferred embodiments. It cannot be determined that the specific implementation of the utility model is only limited to these descriptions. Under the premise of the concept of the utility model, some simple deduction or replacement can also be made, which should be regarded as belonging to the protection scope of the utility model.
