[0002] Fans are common equipment in industrial production processes, used to increase air flow and ventilation. There are three types of fans: centrifugal, axial and mixed flow, which are suitable for different applications. Centrifugal fans are suitable for high pressure and small air volume, axial fans are suitable for low pressure and large air volume, and mixed flow fans are suitable for medium pressure and medium air volume.

[0003] For example, application number CN202010752897.9 discloses a fan impeller, which is not only convenient for the processing and manufacturing of the fan, but also has good sealing between the impeller and the casing, low leakage, low fan noise, smooth operation, high stability and wear resistance, and long service life; however, the above-mentioned device does not have the function of energy storage when it is in operation, and when the fan is in operation, the flow rate out of the air outlet is generally scattered, that is, the air outlet shape of the air outlet is fan-shaped, and when the air outlet is not connected to a special pipe, the side air volume will be lost.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fan with an energy storage device is proposed to achieve a more practical purpose. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fan with an energy storage device, comprising a base, a driving mechanism, a fan body and an energy storage component, wherein the driving mechanism is mounted on the upper end surface of the base, the fan body is arranged on one side of the driving mechanism, the energy storage component is arranged on one side of the fan body, the energy storage component comprises a vacuum shell and a flywheel, the vacuum shell is mounted on the upper end surface of the base, and the inner cavity of the vacuum shell is provided with a flywheel, a transmission shaft is longitudinally provided at the center of the flywheel, and one end of the transmission shaft extends longitudinally from the side wall of the vacuum shell to one side of the vacuum shell, a bearing is provided on the contact surface between the transmission shaft and the vacuum shell, and sealing components are provided on both sides of the bearing.

[0007] Furthermore, the driving mechanism includes a driving motor and a driving wheel, the driving motor is installed on the upper end surface of the base, and the output end of the driving motor is provided with a driving wheel, the outer diameter surface of the driving wheel is provided with a transmission belt, and the inner diameter surface of the transmission belt is transmission-connected to a driven wheel.

[0008] Furthermore, the fan body includes a support frame and a shell, the support frame is installed on the upper end surface of the base, and the shell is installed on the inner side of the support frame, an impeller is arranged at the center of the inner cavity of the shell, an air outlet hood is arranged on the upper end surface of the shell, and an air inlet is arranged on the side end surface of the shell, an air guide groove is arranged on the inner side of the air outlet hood, and an air guide duct is arranged on one side of the air guide groove.

[0009] Furthermore, the driven wheel is specifically installed on one side of the center of the impeller, and the driven wheel is fixedly connected to the impeller. The driving motor forms a belt transmission structure with the impeller through the driving wheel, the transmission belt, and the driven wheel.

[0010] Furthermore, the side of the driven wheel away from the impeller forms a bolt-detachable structure with the transmission shaft through bolts, the flywheel forms a rotating structure rotating around the center of the bearing through the bearing and the vacuum shell, and the air guide groove forms a connecting structure with the air inlet through the air guide pipe.

[0011] Further, the sealing assembly includes a Y-type sealing ring and a Step seal, wherein the Y-type sealing ring and the Step seal are each provided in two groups, wherein the two groups of Step seals are provided between the two groups of Y-type sealing rings, wherein a Gley ring is provided between the two groups of Step seals, wherein sealing rings are provided on the outer surfaces of the Y-type sealing ring, the Step seal and the Gley ring, wherein a piston wear-resistant ring is provided between the Y-type sealing ring, the Step seal and the Gley ring, wherein the Y-type sealing ring, the Step seal, the Gley ring, the sealing ring and the piston wear-resistant ring are installed on the contact surface between the vacuum housing and the transmission shaft and on both sides of the bearing.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the fan with energy storage device stores the rotational force of the impeller through the energy storage assembly, wherein the driving mechanism drives the impeller to rotate and drives the flywheel in the energy storage assembly to rotate, and then the kinetic energy of the impeller rotation is stored through the flywheel, and the inner wall of the air outlet cover is provided with an air guide groove, and then the air volume flowing out along the inner wall of the air outlet cover is re-directed to the air inlet through the air guide groove and the air guide pipe, so as to facilitate the rotation of the impeller, and the device solves the problem of energy storage function and avoiding the loss of air volume at the edge of the air outlet;

[0013] The fan with an energy storage device drives the impeller in the fan body to rotate through a driving mechanism, thereby achieving a blowing effect, wherein the driving motor is started, and the driving motor drives the driving wheel to rotate. Since the driving wheel and the driven wheel form a belt transmission structure through a transmission belt, so that the driven wheel can rotate, and since the driven wheel is installed on one side of the center of the impeller, and the driven wheel is fixedly connected to the impeller, when the driven wheel rotates, the impeller is driven to rotate, so that the impeller draws air from the air inlet, passes through the outer shell, and is finally discharged from the air outlet cover on the upper end surface of the outer shell. In the process of the air being discharged from the air outlet cover, the wind along the inner wall of the air outlet cover will enter the air guide groove, and then flow to the air inlet through the air guide pipe, thereby reducing the loss of the impeller rotation, avoiding the problem of air loss at the edge of the air outlet, and facilitating the rotation of the impeller. Moreover, while the impeller is rotating, the side of the driven wheel away from the impeller is bolted to form a detachable bolt structure with the transmission shaft, thereby driving the transmission shaft to rotate. Since the transmission shaft penetrates the side wall of the vacuum shell and extends to the inner wall of the vacuum shell, and the outer diameter surface of the transmission shaft is fixedly connected to the flywheel, the flywheel is driven to rotate. At this time, the flywheel forms a rotating structure that rotates around the center of the bearing with the side wall of the vacuum shell through the transmission shaft and the bearing, and the rotational force of the flywheel is stored by the flywheel. Since the inner cavity of the vacuum shell is a vacuum structure, the friction force on the flywheel is reduced. At the same time, since the contact surface between the vacuum shell and the transmission shaft is installed with a sealing assembly, the sealing of the device is guaranteed. Through the above structure, the device has the function of storing energy and avoids the problem of air loss at the edge of the air outlet. BRIEF DESCRIPTION OF THE DRAWINGS
