[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the technical scheme in the embodiments of the present application to make a clear and complete description, obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] like Figure 1 As shown, the present invention provides a circumferential blower fan, comprising: a housing 1, a fan 2, and an adjustment mechanism for adjusting the blowing angle of the fan 2; the housing 1 covers the fan 2, the air blown by the fan 2 passes through the housing 1 and blows laterally, and a cold source is provided on the air inlet side of the fan 2.

[0026] It should be noted that the housing 1 is generally cylindrical, and multiple fans 2 are provided to blow air laterally for greater comfort; by providing a cold source, the cooling effect can be improved.

[0027] Multiple fans 2 can be connected together in parallel or in series to enable one switch to control multiple fans 2, or a single switch to control a single fan 2, depending on the needs.

[0028] It should be added here that: the middle part of the housing 1 is provided with a storage cavity 3, and the cold source is placed in the storage cavity 3. The cold source is generally ice. When the ice melts, the water will flow downwards, and some of the water can also play a cooling role. By setting the cold source, the air blown by the fan 2 is lower in temperature and more comfortable.

[0029] The adjustment mechanism includes a gear 4 fixedly mounted on the fan 2 and a rack 5 meshing with the gear 4. When it is necessary to adjust the angle of the fan 2, the gear 4 rotates on the rack 5 to achieve precise angle adjustment. The gear 4 is fixedly mounted on one side of the fan 2, and a rotating shaft is fixedly mounted on the other side of the fan 2. The rotating shaft is rotatably connected to the housing 1, and the rack 5 is detachably fixed to the housing 1 by screws.

[0030] In actual use, the shell 1 is provided with a through hole, the gear 4 is driven to rotate by pulling the gear rack 5 to move, so that the angle of the fan 2 is adjusted, and the gear rack 5 is arranged in an inclined manner.

[0031] As a further improvement, the fan 2 is connected with a power source 6 for driving the fan 2 to rotate, the power source 6 is an electric motor, the power source 6 is connected with a rotating plate 7, the rotating plate 7 is connected with the fan 2 through a connecting piece, and the connecting piece is a telescopic rod 8. The power source 6 can directly drive the fan 2 to rotate to change the range of air outlet, the rotating plate 7 is detachably connected with an extension plate, for example, food can be placed on the extension plate, and the extension plate and the fan 2 are driven to rotate by the electric motor, and the telescopic rod 8 can be a threaded telescopic rod, so that the height can be adjusted conveniently.

[0032] Finally, it should be pointed out that the extension plate can be provided with a water container for containing water melted from ice cubes, and the shell 1 is fixedly provided with a lighting lamp for facilitating light supplement.

[0033] Working principle:

[0034] By arranging the cold source, the temperature of the air blown by the fan 2 is lower, and the user is more comfortable, and by arranging the power source 6, 360-degree air blowing can be realized.
