[0033] Example 1

[0034] Reference Figures 1 to 4 , which is the first embodiment of the utility model, provides a cleaning mechanism, including a replacement component 100 and a cleaning component 200.

[0035] Specifically, the replacement component 100 includes a fan 101, a clamping member 102 arranged on both sides of the inner wall of the fan 101, a limiting member 103 arranged below the clamping member 102, a first spring 104 arranged on the inner wall of the fan 101, a pull ring 105 arranged on the outer wall of the fan 101, and a support member 106 arranged below the limiting member 103 and away from one end of the clamping member 102; and a cleaning component 200, wherein the cleaning component 200 is arranged inside the fan 101, and includes a mounting seat 201, a rotating shaft 202 arranged on the mounting seat 201, and a first cam 203 arranged on the rotating shaft 202.

[0036] Among them, the clamping member 102 is fixedly connected to the first spring 104, the first spring 104 is fixedly connected to the pull ring 105, the mounting seat 201 includes a base plate 201a and a support seat 201b arranged on the base plate 201a, the mounting seat 201 and the support member 106 are connected by bolts, a first through hole 203a is opened in the middle of the first cam 203, the first through hole 203a is located below the center of the first cam 203, the first cam 203 is slidably connected to the rotating shaft 202, the rotating shaft 202 includes a first rotating shaft 202, a second rotating shaft 202 and a third rotating shaft 202, the first rotating shaft 202 and the second rotating shaft 202, the second rotating shaft 202 and the third rotating shaft 202 are detachably connected.

[0037] Operation process: When installing the filter bag, just put the filter bag into the fan 101 and press down. During the pressing process, the fixed part above the filter bag will squeeze the clamp 102. Since the clamp 102 is an inclined surface and is fixedly connected to the first spring 104, the first spring 104 is under pressure during the squeezing process and will move the clamp 102 toward the inner wall. When the clamp 102 is not covered, the filter bag falls on the limiter 103 to achieve the installation of the filter bag. When the filter bag needs to be replaced, just pull the pull ring 105 outward to retract the clamp 102 into the inner wall of the fan 101.

[0038] Example 2

[0039] Reference Figures 1 to 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0040] Specifically, the clamping member 102 is fixedly connected to the first spring 104, the first spring 104 is fixedly connected to the pull ring 105, the mounting seat 201 includes a base plate 201a and a support seat 201b arranged on the base plate 201a, the mounting seat 201 is connected to the support member 106 by bolts, a first through hole 203a is opened in the middle of the first cam 203, the first through hole 203a is located below the center of the first cam 203, the first cam 203 is slidably connected to the rotating shaft 202, the rotating shaft 202 includes a first rotating shaft 202, a second rotating shaft 202 and a third rotating shaft 202, the first rotating shaft 202 and the second rotating shaft 202, the second rotating shaft 202 and the third rotating shaft 202 are detachably connected.

[0041] The rest of the structure is the same as that of Example 1.

[0042] Operation process: During use, you only need to press the forward and reverse motor to make it move. During the movement of the forward and reverse motor, the rotating shaft 202 is driven to move and then the first cam 203 is driven to move. Since the first through hole 203a is located below the center of the first cam 203, the filter bag will be shaken during the movement of the first cam 203. Since a certain gap is left between the limiter 103 and the clamping member 102, the filter bag can be cleaned during the shaking process to shake off the dust attached to the filter bag. By setting up the cleaning component 200, the dust accumulated in the filter bag can be effectively shaken off, which can prevent the efficiency of the fan 101 from being reduced due to clogging of the filter bag.

[0043] Example 3

[0044] Reference Figure 5 and Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0045] Specifically, the latch assembly 300 is arranged on the bottom side wall of the fan 101, including a fixing plate 301, a circular through hole 302 opened on the fixing plate 301, a locking tongue 303 arranged in the circular through hole 302, a first transmission plate 304 arranged on one side of the locking tongue 303, a first square through hole 305 opened on the inner wall of the first transmission plate 304, and a transmission component 306 arranged in the first square through hole 305.

[0046] The fixing plate 301 is arranged on the inner wall of the bottom of the box body, the fixing plate 301 is fixedly provided with a second spring 301a, the locking tongue 303 is slidably arranged in the circular through hole 302, a second limiting plate 304a is arranged on one side of the first transmission plate 304, a second through hole 304b is opened in the second limiting plate 304a, and the transmission component 306 includes a second transmission plate 306a, a second cam 306b arranged on both sides of the second transmission plate 306a, and a second cam 306b opened on the second cam 306b. 06b, a second square through hole 306c arranged in the second square through hole 306c, a main shaft 306d arranged in the second square through hole 306c, and a handle 306e arranged on the main shaft 306d, wherein the second transmission plate 306a is fixedly connected to the first transmission plate 304, and a plurality of limiting columns 306a-1 are arranged on the second transmission plate 306a, and the limiting columns 306a-1 cooperate with the second cam 306b to limit, and the main shaft 306d cooperates with the second square through hole 306c to rotate.

[0047] The remaining structures are the same as those in Example 2.

[0048] Working principle: when closing the bottom of the fan 101, the operator pushes the bottom of the fan 101 upwards. The bottom of the fan 101 includes a box door and a hinge shaft. At this time, the box door rotates around the hinge shaft. When the box door is aligned with the bottom of the fan 101, since the lock tongue 303 has an irregular shape and a chamfer and the fixed plate 301 is fixedly provided with a second spring 301a, when the bottom of the fan 101 is closed, the second spring 301a is squeezed against the fixed plate 301. At this time, the first transmission plate 304 and the second transmission plate 306a move away from the fixed plate 301, and a main shaft 306d is provided in the second square through hole 306c. The rotation of the main shaft 306d will drive the rotation of the second square through hole 306c, and then the second cam 306b drives the limit column 306a-1 to move away from the fixed plate 301. Since the inner wall of the bottom of the fan 101 is provided with a groove to cooperate with the lock tongue 303, When the fan 101 is opened, the operator holds the handle 306e and presses it downward. At this time, since the second square through hole 306c is provided with a main shaft 306d, the rotation of the main shaft 306d will drive the rotation of the second square through hole 306c, and the second cam 306b drives the limiting column 306a-1 to move away from the fixed plate 301, thereby driving the movement of the second transmission plate 306a. Since the second transmission plate 306a is fixedly connected to the first transmission plate 304, the movement of the first transmission plate 304 is driven. The second limiting plate 304a is provided with a second three-through hole, and the lock tongue 303 slides in the second through hole 304b. During the movement of the first transmission plate 304, the second spring 301a is driven to squeeze the fixed plate 301, thereby driving the movement of the lock tongue 303. At this time, the lock tongue 303 is disengaged from the groove on the inner wall of the bottom of the fan 101, thereby achieving the effect of opening the door.
