Description

Technical Field

[0001] The utility model relates to the technical field of umbrellas, in particular to a fan umbrella. Background Technique

[0002] An umbrella is a common daily necessity, mainly used to block rainwater and avoid inconvenience caused by people getting their clothes or bodies wet by rainwater. An umbrella usually consists of an umbrella surface, umbrella ribs, an umbrella handle, umbrella ropes, etc. There are many types of umbrellas, which can be classified according to different classification criteria. By material classification: it can be divided into plastic umbrellas, metal umbrellas, bamboo umbrellas, fabric umbrellas, etc.

[0003] Regarding the above and existing related technologies, the inventor believes that there are often the following defects: A considerable part of umbrellas not only have the ability to block rain but also have a sunshade effect. Sunshade umbrellas are generally used outdoors in high temperatures. In actual use, umbrellas lack other auxiliary heatstroke prevention structures. In the case of relatively high temperatures, simple sunshade umbrellas are prone to the problems of limited and insufficient heatstroke prevention effects. Therefore, a fan umbrella is proposed for the above problems. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background technique.

[0005] The technical solution adopted by the utility model to solve its technical problems is: A fan umbrella of the utility model includes an umbrella body, an electric fan, and a fixing device. The electric fan is located on one side of the umbrella body; a fixing device is provided on the surface of the electric fan. The fixing device includes three magnetic columns. The side walls of the three magnetic columns are fixedly connected to the side wall of the electric fan. The side walls of the magnetic columns and the surface of the umbrella body are magnetically attracted to each other. Two placing blocks are fixedly connected to the side wall of the electric fan. The inner surface of the placing block is rotatably connected to a threaded rod. Two clamping rings are threadedly connected to the surface of the threaded rod. The two clamping rings are sleeved on the surface of the umbrella body. The magnetic columns are attracted to the surface of the umbrella body, and the clamping rings are sleeved on the surface of the umbrella body. By setting the magnetic columns, placing blocks, threaded rod, and clamping rings, the electric fan can be fixed on the umbrella body, reducing the possibility of the electric fan falling off.

[0006] Preferably, two opposite threaded lines are provided on the surface of the threaded rod. A receiving groove is opened on the surface of the placing block. The inner wall of the receiving groove of the placing block and the surfaces of the two clamping rings are slidably connected. When the clamping rings move, the clamping rings slide on the inner wall of the receiving groove of the placing block. The opening of the receiving groove can facilitate the movement of the clamping rings.

[0007] Preferably, a turntable is fixedly connected to the side wall of the threaded rod. A belt is engaged with the inner surfaces of the two turntables. The turntable drives the threaded rod to rotate. By setting the belt and the turntable, the two threaded rods can be driven to rotate simultaneously.

[0008] Preferably, a limiting block is sleeved on the surface of the placing block. A positioning pin is threadedly connected to the inner walls of the limiting block and the placing block. The belt is inserted into the inner surface of the limiting block. By rotating the positioning pin to the inner walls of the limiting block and the placing block, the situation of the belt falling off the surface of the turntable can be reduced by setting the limiting block and the positioning pin.

[0009] Preferably, a support wheel is rotatably connected to the inner surface of the limiting block. The support wheel is located on the surface of the belt. The support wheel rotates on the inner surface of the limiting block. By setting the support wheel, the belt can be supported.

[0010] Preferably, a filtering device is provided on the surface of the electric fan. The filtering device includes a filtering sleeve. The filtering sleeve is sleeved on the surface of the electric fan. Two elastic bands are fixedly connected to the bottom end of the filtering sleeve. A clamping block is fixedly connected to the position of the electric fan surface close to the elastic band. The elastic band is sleeved on the surface of the clamping block. When using the electric fan, push the filtering sleeve to make the filtering sleeve sleeved on the surface of the umbrella body. By setting the filtering sleeve, the electric fan can be filtered, and the possibility of particulate matter entering the interior of the electric fan can be reduced.

[0011] Preferably, two connecting blocks are fixedly connected to the surface of the electric fan. A blocking block is fixedly connected to the upper surface of the connecting block. The filtering sleeve is inserted into the inner walls of the two blocking blocks. When the filtering sleeve moves, the filtering sleeve will be inserted into the inner walls of the blocking blocks on the connecting block. The setting of the connecting block and the blocking block can reduce the possibility of the filtering sleeve warping.

[0012] Preferably, a plurality of filtering holes are formed in the surface of the filtering sleeve. When the electric fan sucks air, the air will pass through the filtering holes of the filtering sleeve. By providing the filtering holes, the air circulation can be facilitated, and at the same time, the particulate matter can be blocked.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. When using the umbrella body in the present utility model, push the electric fan to drive the magnetic column to move. The magnetic column is attracted to the surface of the umbrella body. Then pull the belt to drive the turntable to rotate. The belt moves on the surface of the support wheel and the inner surface of the limiting block. The limiting block is fixed on the surface of the placing block through the positioning pin. The movement of the belt will also drive the support wheel to rotate. The rotation of the turntable will drive the threaded rod to rotate. The threaded rod rotates on the inner surface of the placing block and the inner wall of the clamping ring. The clamping ring will be sleeved on the surface of the umbrella body. By setting the electric fan, the heat dissipation and cooling effect can be increased. At the same time, the magnetic column can fix the electric fan on the surface of the umbrella body, and can also conveniently adjust the height of the electric fan to meet the actual needs. At the same time, other components can reduce the situation of the electric fan rotating or falling off the surface of the umbrella body, and increase the stability after the electric fan is installed.

[0015] 2. Before the electric fan is installed, the utility model pushes the filter sleeve to make the filter sleeve sleeve on the surface of the electric fan. When the filter sleeve moves, it will drive the elastic belt to move. At the same time, part of the structure of the filter sleeve will be inserted into the inner wall of the block on the connecting block. Then, the elastic belt is pulled to stretch the elastic belt, and then the elastic belt is sleeved on the surface of the block. By setting the entire arrangement, the situation of particulate matter entering the electric fan can be reduced, thereby avoiding the possibility of particulate matter damaging or jamming the fan blades.
