Description

Technical Field

[0001] The utility model belongs to the technical field of air-conditioning fans, and in particular relates to an air-conditioning fan with multi-layered filter screen covers. Background Art

[0002] Air conditioning fans are devices that transport gaseous media within air conditioning systems. Currently, centrifugal fans are one of the most common and widely used types. When using a centrifugal fan as an outdoor unit in an air conditioning system, due to the high concentration of debris and dust particles outdoors, a filter screen is required to prevent debris and dust particles from entering the fan and potentially damaging internal components, such as the impeller.

[0003] A search of CN209877298U discloses an air-conditioning fan with a multi-layer filter screen cover. The air inlet protective cover is fixed to the outer end of the air inlet by bolts, and the fine filter screen plate and fine filter cotton layer at the lower part of the exhaust outlet protective plate are inserted into the protective plate mounting groove opened along the upper surface of the exhaust duct. The sealing top plate at the upper end of the exhaust outlet protective plate is fixedly connected to the mounting seat by bolts. The installation and disassembly of the air inlet protective cover and the exhaust outlet protective plate are relatively convenient, and the air inlet protective cover and the exhaust outlet protective plate are convenient to clean.

[0004] The filter plates in the air inlet and exhaust vent of the air conditioner fan are both installed by bolts. Installation by bolts requires the staff to use designated tools and tighten multiple bolts at the same time. The same is true for disassembly. This disassembly and assembly method is relatively cumbersome and has certain limitations, so it is not convenient for disassembly and assembly operations.

[0005] In view of this, the present utility model is proposed. Utility Model Content

The first disassembly and assembly mechanism 31 includes a mounting ring 311 fixedly connected to the outer wall of the fan 1, the inner wall of the mounting ring 311 is provided with a mounting groove 312, the outer wall of the mounting ring 311 is provided with a slot 313, the outer wall of the mounting ring 311 is provided with a first through hole, and the inner wall of the first through hole is slidably provided with a first positioning rod 314, the first positioning rod 314 is fixedly connected to the first fixing plate 315 at one end away from the through hole, and the outer wall of one side of the first fixing plate 315 is fixedly connected to the first spring 316, and the first spring 316 is fixedly connected to the outer wall of the mounting ring 311 at one end away from the first fixing plate 315. The outer wall of the first fixing plate 315 is fixedly connected to the first handle 317, and the inner wall of the mounting groove 312 is slidably engaged with the mounting plate 318. The outer wall of the mounting plate 318 is provided with a positioning hole 319, and the outer wall of one side of the mounting plate 318 is fixedly connected to the protective cover 3110.

[0028] Furthermore, there are four mounting plates 318 , which are symmetrically distributed on the outer wall of the protective cover 3110 in pairs, so as to provide uniform support to the upper, lower, left and right sides of the protective cover 3110 , thereby improving the installation stability of the protective cover 3110 .

[0029] Furthermore, a first inclined surface is provided at one end of the first positioning rod 314 away from the first fixing plate 315, and the outer wall of the first positioning rod 314 fits snugly against the inner wall of the positioning hole 319. The first inclined surface can directly squeeze the first positioning rod 314, thereby facilitating installation.

[0030] Furthermore, the inner wall of the mounting groove 312 fits snugly with the outer wall of the mounting plate 318 , thereby ensuring a tight fit between the outer wall of the mounting plate 318 and the inner wall of the mounting groove 312 , thereby improving the stability of the mounting plate 318 during the engagement process.

[0031] The second disassembly and assembly mechanism 32 includes a fixed base 321 fixedly connected to the top of the fan 1, a filter plate 326 is engaged with the inner wall of the fixed base 321, a second through hole is opened on the outer wall of the fixed base 321, a second positioning rod 322 is slidably provided on the inner wall of the second through hole, one end of the second positioning rod 322 is fixedly connected to the second fixing plate 323, the outer wall of one end of the second fixing plate 323 is fixedly connected to the second spring 324, the second spring 324 is fixedly connected to the outer wall of the fixed base 321 at one end away from the second fixing plate 323, and a second handle 325 is fixedly connected to the outer wall of one side of the second fixing plate 323.

[0032] Furthermore, there are two second positioning rods 322, and the second positioning rods 322 are distributed on the left and right sides of the fixing seat 321 in a left-right symmetrical structure, so as to simultaneously limit the left and right sides of the top of the filter plate 326, thereby further improving the installation stability of the filter plate 326.

[0033] Furthermore, a second inclined surface is provided at one end of the second positioning rod 322 away from the second fixing plate 323 . The second inclined surface can directly produce an extrusion effect on the second positioning rod 322 , thereby facilitating installation.

[0034] The implementation principle of the air-conditioning fan with a multi-layer filter screen cover of this embodiment is as follows: when installing the protective cover 3110, first align the mounting plate 318 with the slot 313 and then insert it into it. At this time, the outer wall of the mounting plate 318 will fall into the mounting groove 312, and then the protective cover 3110 can be rotated. The rotation of the protective cover 3110 can drive the mounting plate 318 to rotate on the inner wall of the mounting groove 312. During the rotation of the mounting plate 318, it will contact and squeeze the first positioning rod 314. The squeezed first positioning rod 314 will move to the left, and during the movement, it will drive the first fixing plate 315 to move. At the same time, when the first fixing plate 315 moves, it will stretch the first spring 316. As the protective cover 3110 continues to rotate, the mounting plate 31 When the locking cam 318 is in the unlocking state, the locking cam 318 is unlocked and the locking cam 318 is in the unlocking state.

[0035] When the filter plate 326 is installed, the filter plate 326 is directly inserted into the fixing seat 321. During the insertion process, the filter plate 326 will contact and squeeze the second positioning rod 322. The squeezed second positioning rod 322 will move to the right side. At the same time, the second fixing plate 323 will move during the movement. Then, the second fixing plate 323 drives the second spring 324 to stretch. Then, the filter plate 326 is pushed downward until the filter plate 326 is fully inserted into the fixing seat 321. Then, its top end passes over the second positioning rods 322 on both sides. Then, the second spring 324 can rebound and push the second positioning rod 322 to reset and limit the top end of the filter plate 326 to complete the installation. When removing, just pull the second handle 325 to drive the second positioning rod 322 to separate from the top end of the filter plate 326, and then pull the filter plate 326 out of the fixing seat 321.
