Description

Technical Field

[0001] The utility model relates to the technical field of cooling fans, and specifically relates to a cooling fan for machining. Background Technique

[0002] The blades of the cooling fan push air to flow in the same direction as the axis. The impeller of the cooling fan is somewhat similar to a propeller. When it is working, the flow direction of most of the air flow is parallel to the axis. When the inlet air flow of the cooling fan is free air with zero static pressure, its power consumption is the lowest. When it is running, the power consumption will increase with the rise of the air flow back pressure. The cooling fan is usually installed on the electrical equipment cabinet and sometimes integrated on the motor. Because the cooling fan has a compact structure, it can save a lot of space and is convenient to install, so it is widely used.

[0003] According to the "A Cooling Fan for Machining (Publication No.: CN 221401016 U; Application No.: 202323534047.X)" announced on the patent network, the above application aims at the problem that "when the existing fan is in use, due to its single structure, it can only blow and dissipate heat in a single direction, which limits its overall heat dissipation range. When dissipating heat at a higher location, it can only be placed at the corresponding higher position, which is more troublesome to use and has low practicability". However, when the cooling fan in the above application is in use, like the existing cooling fan, it cannot filter the passing air, and dust and water vapor in the external air will enter the device and contact the internal components of the device, affecting the internal heat dissipation effect of the device and being inconvenient to use.

[0026] The present utility model provides a technical solution:

[0027] Embodiment 1

[0031] Furthermore: The filter plate 1202 is arranged inside the fixing frame 1101 to filter the air passing through the heat dissipation fan main body 3 when the heat dissipation fan main body 3 is started, so that dust and water vapor in the external air will not affect the internal components of the device, improving the air cleanliness of the airflow formed when the heat dissipation fan main body 3 is in use. At the same time, the clamping frame 1201 and the filter plate 1202 can be disassembled and assembled, enabling the staff to replace the filter plate 1202 regularly, ensuring that the filter plate 1202 can always maintain the filtering effect on the external air when the heat dissipation fan main body 3 is in use.

[0032] Embodiment 2

[0033] Refer to Figures 1 to 5, and on the basis of the first embodiment, it is further obtained that the fixing mechanism 2 includes a clamping component 21, a positioning component 22, and a pulling component 23. The clamping component 21 is arranged inside the left and right sides of the protection component 11. The positioning component 22 is arranged above the clamping component 21 on the left and right sides of the main body of the heat dissipation fan 3. The pulling component 23 is arranged inside the outside of the positioning component 22.

[0034] The clamping component 21 includes a clamping rod 2101. The clamping rod 2101 is clamped inside the left and right sides of the fixing frame 1101. The fixing frame 1101 is clamped inside the left and right sides of the clamping frame 1201. A limiting plate 2102 is fixedly connected to the outside of the clamping rod 2101. A sleeve frame 2103 is sleeved on the outside of the limiting plate 2102. The sleeve frame 2103 is fixedly connected to the left and right sides of the fixing frame 1101. A pulling frame 2104 is fixedly connected to the outside of the limiting plate 2102. A reinforcing arm 2105 is fixedly connected to the top inside of the pulling frame 2104. The reinforcing arm 2105 is fixedly connected to the outside of the limiting plate 2102. The positioning component 22 includes a fixing cylinder 2201. The fixing cylinder 2201 is fixedly connected to the left and right sides of the fixing frame 1101 above the sleeve frame 2103. A sliding cylinder 2202 is slidably connected inside the fixing cylinder 2201. A compression spring 2203 is fixedly connected to the top inside of the sliding cylinder 2202. A positioning rod 2204 is fixedly connected to the bottom of the sliding cylinder 2202. A sleeve block 2205 is sleeved on the outer circle of the positioning rod 2204. The sleeve block 2205 is fixedly connected to the outside of the limiting plate 2102. The pulling component 23 includes a moving sliding rod 2301. The moving sliding rod 2301 is fixedly connected to the outside of the sliding cylinder 2202. The moving sliding rod 2301 is slidably connected inside the outside of the fixing cylinder 2201. A dial rod 2302 is fixedly connected to the outside of the moving sliding rod 2301.

[0035] Furthermore: The staff only needs to dial the dial rod 2302 and the pulling frame 2104 to complete the disassembly and assembly of the clamping rod 2101, so that the clamping rod 2101 achieves or releases the connection between the fixing frame 1101 and the clamping frame 1201, enabling the staff to quickly complete the disassembly and assembly of the clamping frame 1201. The operation is simple and convenient for the staff to use.

[0036] During the actual operation process, when this device is in use, the main body of the heat dissipation fan 3 starts to pump the outside air to pass through the inside of the heat dissipation fan 3 from front to back, so that the outside air enters the device to complete the heat dissipation treatment of the inside of the machining device. Before the outside air enters the inside of the machining device, it first contacts the filter plate 1202. During the process of the outside air passing through the filter plate 1202 backward, the filter plate 1202 intercepts the dust and water vapor in the air to complete the filtration of the outside air, so that the air entering the inside of the machining device does not carry dust and water vapor into the inside of the machining device;

[0037] When the filter plate 1202 needs to be replaced, the staff first move the lever 2302 upward. The upward movement of the lever 2302 drives the sliding cylinder 2202 upward through the moving sliding rod 2301. The upward movement of the sliding cylinder 2202 drives the positioning rod 2204 upward. The upward movement of the positioning rod 2204 retracts into the clamping rod 2101 to release the connection with the sleeve block 2205. Then, the staff move the pull frames 2104 on the left and right outward. The outward movement of the pull frames 2104 drives the clamping rod 2101 outward through the limiting plate 2102. The outward movement of the clamping rod 2101 disengages from the connections with the fixed frame 1101 and the clamping frame 1201. Then, the staff only need to pull the lifting rod 1302 upward to drive the clamping frame 1201 upward. The upward movement of the clamping frame 1201 disengages from the connection with the fixed frame 1101. At this time, the disassembly process of the filter plate 1202 is completed;

[0038] Then, the staff insert the new clamping frame 1201 and filter plate 1202 into the top of the fixed frame 1101. After the bottom of the limiting piece 1203 fits with the top of the fixed frame 1101, the staff move the levers 2302 on the left and right upward, and then insert the clamping rod 2101 into the left and right sides of the fixed frame 1101. After the limiting plate 2102 is clamped in the sleeve frame 2103, the staff release the limit on the levers 2302 on the left and right. At this time, the sliding cylinders 2202 on the left and right drive the positioning rod 2204 downward under the action of the compression spring 2203. The downward movement of the positioning rod 2204 is clamped in the inner ring of the sleeve block 2205 to complete the positioning of the clamping rod 2101. At this time, the installation of the filter plate 1202 is completed, and the replacement of the filter plate 1202 is completed.
