Description

Technical Field

[0001] The utility model relates to the technical field of fan devices, in particular to a fan with double suction ports for uniform air supply. Background Art

[0002] A double inlet fan is a fan with two air inlets. This fan is often used in applications where higher flow rates are required because it can draw air through both inlets simultaneously, thereby improving efficiency and performance.

[0003] When the double-suction fan is working, the suction area increases due to the increase in air intake flow. If it rains, when the double-suction fan is working and sucking air, due to the increase in the suction area, it is very likely that rainwater will also be sucked into the device. If too much rainwater is sucked in, it will cause faults such as moisture inside the fan, impeller corrosion, and water ingress to the motor. These faults will affect the normal operation of the fan, thereby reducing the service life of the fan itself. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a double-suction fan with uniform air supply.

[0005] The utility model is implemented by the following technical scheme: a fan with double suction ports and uniform air supply, comprising a fan body, a splitter plate is arranged at one end of the fan body, both sides of the splitter plate are air inlets, and a shielding component is arranged on one side of the upper surface of the fan body;

[0006] The shielding assembly includes a support frame, the bottom end of the support frame is fixedly connected to the upper surface of the fan body, the top end of the support frame is fixedly connected to a protective top cover, both sides of the protective top cover are fixedly connected to side baffles, and one side of the side baffle is fixedly connected to the outer surface of the fan body.

[0007] Through the above technical solution, the protective top cover and the side baffles are used together to protect the air inlet of the fan body, so as to prevent the air inlet of the fan body from being directly exposed to the rain in rainy weather. Rainwater may be sucked into the fan, causing the fan to become damp, the impeller to corrode, the motor to get water in, and other faults. These faults will reduce the efficiency and service life of the fan body, and may even cause damage to the fan body. The setting of the splitter plate produces two air inlets of uniform size. The design of the double air inlet can provide a more stable airflow. Even if one air inlet is blocked, the other air inlet can still guarantee a certain airflow supply, which is very important for maintaining the stable operation of the fan.

[0008] As a further improvement of the above solution, a filter screen is fixedly connected to the surface of the air inlet, and a plurality of filter holes are formed on the outer surface of the filter screen.

[0009] Through the above technical solution, the filter screen can block dust, dirt and large particles from entering the fan, thereby preventing these substances from causing wear or damage to the internal components of the fan. At the same time, the clean air inlet can improve the fan's suction efficiency and ensure that the fan operates in the best condition.

[0010] As a further improvement of the above solution, there are two support frames, which are fixedly connected to two sides of the upper surface of the fan body respectively.

[0011] Through the above technical solution, there are two support frames, which can improve the stability of the connection between the protective top cover and the fan body and prevent the protective top cover from being affected by external forces and shaking and falling.

[0012] As a further improvement of the above solution, a protection base is fixedly connected to the bottom of the fan body, and connecting horizontal blocks are fixedly connected to both sides of the upper surface of the protection base.

[0013] Through the above technical solution, the protective base is usually made of rubber, springs or other materials with shock-absorbing properties, which can effectively isolate the vibration generated when the fan is running, thereby reducing noise, helping to prevent wear of the internal parts of the fan due to long-term vibration, extending the service life of the equipment and improving user comfort.

[0014] As a further improvement of the above solution, positioning grooves are provided on both sides of the surface of the connecting horizontal block.

[0015] Through the above technical solution, the setting of the positioning groove can facilitate personnel to install the limiting beam, thereby improving the stability of the fan body.

[0016] As a further improvement of the above solution, a limiting cross beam is arranged inside the positioning groove, and the limiting cross beam is adapted to the positioning groove.

[0017] Through the above technical solution, the limiting beam is inserted into the positioning groove, which can secondary fix the outer surface of the fan body, avoid the fan body being affected by external forces, causing the fan body to tilt and shake, and improve the fixing effect of the fan body.

[0018] As a further improvement of the above solution, a rubber shock-absorbing pad is fixedly connected to the lower surface of the protection base. There are four rubber shock-absorbing pads, which are respectively fixedly connected to the four corners of the lower surface of the protection base.

[0019] Through the above technical solution, the provision of rubber shock-absorbing pads improves the seismic performance of the fan body during operation. The rubber shock-absorbing pads are evenly arranged at the four corners of the lower surface of the protective base, so that each area of ​​the bottom of the protective base can be evenly stressed and will not cause local stress damage.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] The utility model can protect the air inlet of the fan body by setting a shielding component, and the protective top cover and the side baffles are used together to prevent the air inlet of the fan body from being directly exposed to the rain in rainy weather. Rainwater may be sucked into the fan, causing the fan to be damp, the impeller to corrode, the motor to be watered, and other faults. These faults will reduce the efficiency and service life of the fan body, and may even cause damage to the fan body. The design of the double air inlet can provide a more stable and uniform airflow. Even if one air inlet is blocked, the other air inlet can still guarantee a certain airflow supply, thereby improving the stability of the fan during operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The shielding assembly 4 includes a support frame 401, the bottom end of the support frame 401 is fixedly connected to the upper surface of the fan body 1, the top end of the support frame 401 is fixedly connected with a protective top cover 402, both sides of the protective top cover 402 are fixedly connected with side baffles 403, one side of the side baffles 403 is fixedly connected to the outer surface of the fan body 1, and the protective top cover 402 and the side baffles 403 are used together to protect the air inlet 3 of the fan body 1, so as to prevent the air inlet 3 of the fan body 1 from being directly exposed to the rain in rainy weather, and rainwater may be sucked into the fan, resulting in the fan being damp, the impeller corroded, the motor being watered, and other faults. These faults will reduce the efficiency and service life of the fan body 1, and may even cause damage to the fan body 1. The setting of the diverter plate 2 produces two air inlets 3 of uniform size. The design of the double air inlet 3 can provide a more stable airflow. Even if one air inlet 3 is blocked, the other air inlet 3 can still guarantee a certain airflow supply, which is very important for maintaining the stable operation of the fan.

[0033] The surface of the air inlet 3 is fixedly connected with a filter screen 5, and the outer surface of the filter screen 5 is provided with a plurality of filter holes. The filter screen 5 can block dust, dirt and large particles from entering the fan, thereby preventing these substances from causing wear or damage to the internal components of the fan. At the same time, a clean air inlet can improve the air suction efficiency of the fan and ensure that the fan operates in the best condition.

[0034] There are two support frames 401, which are fixedly connected to both sides of the upper surface of the fan body 1. There are two support frames 401, which can improve the stability of the protective top cover 402 when connected to the fan body 1, and prevent the protective top cover 402 from being affected by external forces and shaking and falling.

[0035] A protective base 6 is fixedly connected to the bottom of the fan body 1, and connecting cross blocks 7 are fixedly connected to both sides of the upper surface of the protective base 6. The protective base 6 is usually made of rubber, spring or other materials with shock-absorbing properties, which can effectively isolate the vibration generated when the fan is running, thereby reducing noise, helping to prevent wear of the internal parts of the fan due to long-term vibration, extending the service life of the equipment, and improving the comfort of the user.

[0036] Positioning grooves 8 are provided on both sides of the surface of the connecting cross block 7 . The arrangement of the positioning grooves 8 can facilitate personnel to install the limiting cross beam 9 , thereby improving the stability of fixing the fan body 1 .

[0037] A limiting cross beam 9 is arranged inside the positioning groove 8, and the limiting cross beam 9 is adapted to the positioning groove 8. The limiting cross beam 9 is inserted into the positioning groove 8, which can fix the outer surface of the fan body 1 for a second time, thereby preventing the fan body 1 from being affected by external forces, causing the fan body 1 to tilt and shake, and improving the fixing effect of the fan body 1.

[0038] A rubber shock-absorbing pad 10 is fixedly connected to the lower surface of the protective base 6. There are four rubber shock-absorbing pads 10, which are respectively fixedly connected to the four corners of the lower surface of the protective base 6. The setting of the rubber shock-absorbing pad 10 improves the seismic performance of the fan body 1 during operation. The rubber shock-absorbing pad 10 is evenly arranged at the four corners of the lower surface of the protective base 6, which can make the various areas at the bottom of the protective base 6 evenly stressed, and will not cause local stress damage.

[0039] The implementation principle of a double-suction fan with uniform air supply in the embodiment of the present application is as follows: the setting of the diverter plate 2 produces two air inlets 3 of uniform size. The design of the double air inlet 3 can provide a more stable airflow. Even if one air inlet 3 is blocked, the other air inlet 3 can still guarantee a certain airflow supply, which is very important for maintaining the stable operation of the fan. The filter screen 5 can block dust, dirt and large particles from entering the fan, thereby preventing these substances from causing wear or damage to the internal components of the fan. At the same time, a clean air inlet can improve the air suction efficiency of the fan and ensure that the fan operates in the best condition. The protective top cover 402 and the side baffle 403 are used together to protect the air inlet 3 of the fan body 1 to prevent the air inlet 3 of the fan body 1 from being directly exposed to the rain in rainy weather. Rainwater may be sucked into the fan, causing the fan to be damp, the impeller to corrode, the motor to be water ingress and other faults. These faults will reduce the efficiency and service life of the fan body 1 and may even cause damage to the fan body 1. The air inlet 3 of the fan body 1 can be effectively protected by the protective top cover 402 and the side baffle 403, thereby extending the service life of the equipment. The protective base 6 is usually made of rubber, springs or other materials with shock-absorbing properties, which can effectively isolate the vibration generated during the operation of the fan, thereby reducing noise, helping to prevent wear of the internal parts of the fan due to long-term vibration, extending the service life of the equipment, and improving the comfort of the user.

[0040] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
