Technical Field

[0001] The present application relates to the technical field of fans, and in particular to an adaptive fluid dynamic shock-absorbing fan. Background Art

[0002] At present, fans can achieve the effect of ventilation and heat dissipation. The function of the fan in the wall-mounted boiler is to suck the air required for combustion into the combustion chamber and discharge the smoke generated after combustion to the outside. Therefore, in addition to meeting the air volume required for combustion, the fan must also have a certain pressure head to overcome the resistance of the smoke exhaust system.

[0003] In the related art, when the fan is working in the wall-mounted boiler, the motor and motor bracket of the existing wall-mounted boiler fan are connected by screws, which causes great vibration during use and easily causes parts to loosen, thereby affecting the service life of the wall-mounted boiler. Summary of the invention

[0004] In order to improve the problem that the wall-mounted boiler fan has large vibration during operation, resulting in a reduced service life, the present application provides an adaptive fluid dynamic shock-absorbing fan.

[0005] The present application provides an adaptive fluid dynamic shock-absorbing fan adopting the following technical solution: An adaptive fluid dynamic shock-absorbing fan comprises a fan body, the fan body is connected to a motor body, a motor bracket foot is arranged on the side wall of the motor body, the motor bracket foot and the motor body are integrally formed, and the motor bracket foot is connected to the motor body.

[0006] By adopting the above technical solution, the motor bracket foot and the motor body are integrally formed, so that the structural integrity is higher, and the motor body and the fan body can be more tightly connected during the connection process, and the overall structure can further withstand greater pressure and impact, making the fan more durable during long-term use, and reducing the risk of damage due to external force or vibration. At the same time, the more compact and sturdy structure can more effectively transfer and dissipate heat during operation, avoiding the risk of local overheating and damage, and can also reduce the risk of failure caused by loose or damaged connections, making installation and maintenance more convenient. The more compact structure helps to reduce the noise transmitted during the operation process, and further, it can also improve the overall aesthetics of the fan, making the overall appearance of the fan more simple and smooth.

[0007] As a preferred solution of the present invention, a plurality of motor support legs are evenly arranged along the axial direction of the motor body.

[0008] By adopting the above technical solution and setting a plurality of motor bracket feet, the load between the motor body and the fan body can be distributed more evenly, and the force concentration on a single connection point can be reduced, thereby reducing the risk of loosening or damage caused by overload or vibration. At the same time, the overall seismic performance of the fan can be increased, ensuring that the connection between the fan body and the motor body is more stable. At the same time, it is also convenient to adjust the connection method and connection position between the motor body and the fan body, thereby optimizing the power transmission efficiency between the fan body and the motor body, reducing energy loss, and improving the overall operating efficiency. Furthermore, it also makes the installation and disassembly between the fan body and the motor body more flexible, making maintenance work more convenient and efficient, reducing maintenance costs and maintenance time. Finally, it can also improve the overall stability and seismic resistance of the fan, and to a certain extent, it can also protect the motor body and the fan body.

[0009] As a preferred solution of the present invention, the cross section of the motor bracket foot is C-shaped, and the C-shaped opening of the motor bracket foot faces the outside of the motor body.

[0010] By adopting the above technical solution, the connection and installation between the motor body and the fan body can be facilitated, obstructions during installation can be reduced, and the installation process can be made more convenient.

[0011] As a preferred solution of the present invention, a connecting seat is provided on the side wall of the fan body close to the motor body, and the connecting seat is arranged corresponding to the motor bracket foot. The connecting seat is used to connect with the motor bracket foot, and the motor bracket foot is passed through a connecting bolt, and the end of the connecting bolt extends to the connection.

[0012] By adopting the above technical solution, the fan body is connected to the motor body by passing the connecting bolts through the motor bracket foot and the connecting seat. The connection structure is simple and compact with high integrity, which can effectively enhance the overall stability of the fan and reduce vibration during operation.

[0013] As a preferred solution of the present invention, a shock-absorbing rubber ring is provided between the connecting seat and the motor bracket foot.

[0014] By adopting the above technical solution, the shock-absorbing rubber ring can improve the integrity while reducing the vibration during operation. At the same time, the shock-absorbing rubber ring can also play a role of heat insulation, effectively reducing the heat of the flue gas from being transferred through the fan body to the inside of the motor body during use, thereby increasing the overall service life of the fan.

[0015] As a preferred embodiment of the present invention, an impeller assembly is provided on the fan body, and the impeller assembly is connected to the motor body. The impeller assembly includes inner blades and outer blades. The inner blades are rotatably connected to the inside of the fan body, and the outer blades are rotatably connected between the fan body and the motor body.

[0016] By adopting the above technical solution, the simultaneous setting of inner and outer blades can disperse the load of the fan during overall operation, reduce the force concentration on a single component, help improve the overall structural strength and stability of the fan, and extend its service life. During operation, the fan as a whole may be subject to vibration and impact from all directions. The design of inner and outer blades can increase the overall shock resistance of the fan and reduce the risk of damage caused by vibration; the inner blades can effectively push the airflow toward the outlet direction of the fan body, providing the necessary oxygen for the combustion process of the wall-mounted boiler; the outer blades are set in the transition area between the motor body and the fan body, which can effectively take away the heat around the motor body and reduce the temperature of the motor body, thereby protecting the motor body from overheating damage. At the same time, the outer blades can also balance the aerodynamic force, by adjusting the direction and speed of the airflow, reducing the vibration and noise caused by uneven airflow, and ensuring the stable operation of the fan.

[0017] As a preferred solution of the present invention, the inner blades are arranged in a ring shape, the inner blades are arranged perpendicular to the axial direction of the fan body, and the center of the inner blades is consistent with the center of the fan body.

[0018] By adopting the above technical solution, the inner fan blades are set in a ring shape, so that the airflow forms a complete ring flow, which can effectively enhance the stability of the airflow, guide the airflow to pass through the fan more smoothly, reduce airflow turbulence and eddy currents, and enable the fan body to produce a larger air volume and air pressure at the same speed. Furthermore, the noise generated by the inner fan blades when running at high speed can be significantly reduced. At the same time, the inner fan blades are set in a ring shape, which significantly improves the sealing of the inner fan blades, can reduce the interference of the airflow, and can also play a reinforcement role, and can enhance the anti-bending and anti-vibration performance, thereby effectively improving the service life and reducing maintenance.

[0019] As a preferred solution of the present invention, the outer fan blade is provided with an outward expansion blade, the outward expansion blade is evenly arranged in a circle along the circumference of the outer fan blade, and the outward expansion blade is arranged toward the motor body.

[0020] By adopting the above technical solution, the outward-expanding blades can accelerate the air flow around the motor body, thereby effectively dissipating the heat and cooling the motor body. When the motor body drives the impeller assembly to rotate, the outward-expanding blades can help guide the air outside the fan body, so that the air can quickly flow into the fan body. At the same time, it can also better achieve the air compression and acceleration effects, and ensure that the aerodynamic force generated by the impeller assembly during rotation is balanced, reducing vibration and noise caused by unbalanced aerodynamic force, reducing damage to the impeller assembly, and thus extending the life of the impeller assembly.

[0021] As a preferred solution of the present invention, reinforcement teeth are arranged on the side wall of the motor body close to the fan body, and the reinforcement teeth are integrally formed with the motor body.

[0022] By adopting the above technical solution, the reinforcing teeth can effectively reinforce the motor body, and the reinforcing teeth can also increase the integrity of the motor body, making the motor body more stable during operation and reducing the vibration of the motor body, thereby further reducing the damage to the motor body and extending the life of the motor body.

[0032] The fan body 1 includes a volute 11 and an impeller assembly 13. The volute 11 includes a front cover plate 111 and a rear cover plate 112. The front cover plate 111 and the rear cover plate 112 are abutted against each other to form an air collecting cavity 113 between the front cover plate 111 and the rear cover plate 112. An air inlet 114 is opened at the center of the upper edge of the front cover plate 111.

[0034] The simultaneous arrangement of the inner blades 131 and the outer blades 132 can disperse the load during the overall operation of the fan, reduce the force concentration on a single component, help to improve the overall structural strength and stability of the fan, and extend its service life. During operation, the fan as a whole may be subjected to vibration and impact from all directions. The design of the inner blades 131 and the outer blades 132 can increase the overall shock resistance of the fan and reduce the risk of damage caused by vibration; the inner blades 131 can effectively push the airflow toward the outlet direction of the fan body 1 to provide the necessary oxygen for the combustion process of the wall-mounted boiler; the outer blades 132 are arranged in the transition area between the motor body 2 and the fan body 1, which can effectively take away the heat around the motor body 2 and reduce the temperature of the motor body 2, thereby protecting the motor body 2 from overheating damage. At the same time, the outer blades 132 can also balance the aerodynamic force, by adjusting the direction and speed of the airflow, reducing the vibration and noise caused by uneven airflow, and ensuring the stable operation of the fan.

[0035] The inner blades 131 are arranged in a ring shape, and are arranged perpendicular to the axial direction of the fan body 1 . The center of the inner blades 131 is consistent with the center of the fan body 1 .

[0036] The inner fan blades 131 are set in a ring shape so that the airflow forms a complete ring flow, which can effectively enhance the stability of the airflow, guide the airflow to pass through the entire fan more smoothly, reduce airflow turbulence and eddy currents, and enable the fan body 1 to generate a larger air volume and air pressure at the same rotation speed. Furthermore, the noise generated by the inner fan blades 131 when running at high speed can be significantly reduced. At the same time, the inner fan blades 131 are set in a ring shape, which significantly improves the sealing of the inner fan blades 131, can reduce the interference of the airflow, and can also play a reinforcement role, and can enhance the anti-bending and anti-vibration performance, thereby effectively improving the service life and reducing maintenance.

[0039] The motor bracket foot 21 is formed integrally with the motor body 2, so that the structural integrity is higher, and the motor body 2 and the fan body 1 can be more tightly connected during the connection process, and the overall structure can further withstand greater pressure and impact, making the fan more durable during long-term use and reducing the risk of damage due to external force or vibration. At the same time, the more compact and sturdy structure can more effectively transfer and dissipate heat during operation, avoiding the risk of local overheating and damage, and can also reduce the risk of failure caused by loose or damaged connections, making installation and maintenance more convenient. The more compact structure helps to reduce the noise transmitted during the operation process, and further, it can also enhance the overall aesthetics of the fan, making the overall appearance of the fan more simple and smooth.

[0040] A plurality of motor support legs 21 are evenly arranged along the axial direction of the motor body 2 .

[0041] By providing a plurality of motor bracket feet 21, the load between the motor body 2 and the fan body 1 can be distributed more evenly, and the force concentration on a single connection point can be reduced, thereby reducing the risk of loosening or damage caused by overload or vibration. At the same time, the overall anti-seismic performance of the fan can be increased, ensuring that the connection between the fan body 1 and the motor body 2 is more stable. At the same time, it is also convenient to adjust the connection method and connection position between the motor body 2 and the fan body 1, thereby optimizing the power transmission efficiency between the fan body 1 and the motor body 2, reducing energy loss, and improving the overall operating efficiency. Furthermore, it also makes the installation and disassembly between the fan body 1 and the motor body 2 more flexible, making maintenance work more convenient and efficient, reducing maintenance costs and maintenance time. Finally, it can also improve the overall stability and anti-seismic performance of the fan, and to a certain extent, it can also protect the motor body 2 and the fan body 1.

[0046] A shock-absorbing rubber ring 23 is arranged between the connecting seat 12 and the motor bracket foot 21 , and the cross section of the shock-absorbing rubber ring 23 along the axial direction is arranged in an I-shape.

[0047] The shock-absorbing rubber ring 23 can improve the integrity while reducing vibration during operation.

[0050] The implementation principle of an adaptive fluid dynamic shock-absorbing fan in an embodiment of the present application is as follows: during operation, the inner blades 131 and the outer blades 132 are driven to rotate by the motor body 2, thereby transmitting the airflow. The combination of the inner and outer blades 132 can disperse the load of the overall operation of the fan, which helps to improve the overall structural strength and stability of the fan.
