[0024] The embodiment of the present invention is intended to introduce and illustrate the structural composition of the air pollution purification device for easily compressible dust and the coordination relationship between the various components. Unless otherwise specified, the size, material and manufacturing process of each component in the air pollution purification device suitable for easily compressible dust in the embodiment of the present invention can be selected according to the specific situation and are not specifically limited or explained here.

[0025] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0026] Please also read Figure 1-Figure 5 , this embodiment provides an air pollution purification device for easily compressible dust, including a filter box 10, an exhaust fan 11, a partition 12, a filter plate 13, an activated carbon plate 14, a limiting wedge 15, an ash receiving plate 2, a lifting component 3, a transmission mechanism 4, a collection box 5 and an ash pressing component 6; The exhaust fan 11 is arranged at one end of the filter box 10, the partition 12 is fixed in the filter box 10, the filter plate 13 is arranged on the partition 12, the activated carbon plate 14 is arranged in the filter box 10 on the side away from the exhaust fan 11, and the collection box 5 is arranged in the filter box 10 on the side close to the exhaust fan 11; specifically, the partition 12 and the filter plate 13 together divide the filter box 10 into two parts, the ash filter area and the activated carbon area. The exhaust fan 11 is started to draw air into the ash filter area, and then the air passes through the filter plate 13 into the activated carbon area, and finally is discharged from the other side of the filter box 10 after passing through multiple activated carbon plates 14. The collection box 5 is located in the ash filter area.

[0027] The limiting wedge 15 is arranged in the filter box 10. The filter box 10 is provided with a lifting slot 101. The lifting component 3 can be lifted and lowered in the lifting slot 101. The ash plate 2 is rotatably connected to the lifting component 3. When the ash plate 2 abuts the limiting wedge 15, it is in a flat state and can be rotated toward the collection box 5 as the lifting component 3 is lifted. It should be understood that the ash plate 2 is connected to the lifting component 3 through hinges and hinges 22, etc., and can be lifted as the lifting component 3 is lifted. Due to its own rotatable characteristics, when the ash plate 2 is lifted, it gradually rotates toward the collection box 5, so that the dust on it falls into the collection box 5. When the lifting component 3 descends, the ash plate 2 rotates in the direction away from the collection box 5 under the pressure of the limiting wedge 15 until it is flat. It is also worth mentioning that the inclined surface of the limiting wedge 15 faces The transmission mechanism 4 is rotatably disposed in the lifting groove 101, and the descent of the lifting assembly 3 can drive the transmission mechanism 4 to rotate forward in one direction; that is, the rise of the lifting assembly 3 cannot drive the transmission mechanism 4 to reverse. The ash pressing assembly 6 is slidably disposed in the filter box 10 and the collection box 5, and is connected to the transmission mechanism 4. The rotation of the transmission mechanism 4 can drive the ash pressing assembly 6 to slide back and forth. Specifically, the sliding stroke of the ash pressing assembly 6 is from one side of the collection box 5 to the other side. By setting the stroke of the descent of the lifting assembly 3 to drive the transmission mechanism 4 to rotate forward, the ash pressing assembly 6 performs a periodic motion of an integer multiple with a cycle of completing a reciprocating motion, so that the ash pressing assembly 6 is always on one side of the collection box 5 when it stops moving.

[0028] In the present application, dust and the like in the air entering the filter box 10 are intercepted by the filter plate 13 and fall on the ash receiving plate 2. The ash receiving plate 2 is rotated toward the collection box 5 by the lifting of the lifting component 3, so that the dust falls into the collection box 5. During this process, the ash pressing component 6 remains stationary due to the unidirectional rotation characteristics of the transmission mechanism 4; the lifting component 3 rises to the maximum height and then begins to descend, thereby driving the transmission mechanism 4 to rotate forward and causing the ash pressing component 6 to slide by an integer multiple of its back and forth stroke, thereby compressing the components in the collection box 5 and stopping at the initial position, that is, one side of the collection box 5.

[0029] In other schemes, the lifting assembly 3 includes a lead screw 31, a ball nut 32 and a rack 33; the lead screw 31 is rotatably connected to the lifting slot 101 and passes through the top of the filter box 10, the ball nut 32 is screwed on the lead screw 31, and the ash receiving plate 2 is rotatably arranged on the ball nut 32; the rack 33 is slidably connected to the lifting slot 101 and is fixedly connected to the ball nut 32, and the descent of the rack 33 can unidirectionally drive the transmission mechanism 4 to rotate forward. It should be understood that the rack 33 slides along the axial direction of the lead screw 31. Preferably, a click can also be set on the lead screw 31, and the forward and reverse rotation of the click can be controlled to control the lifting and lowering of the ball nut 32.

[0030] In other schemes, the transmission mechanism 4 includes a gear ring 41, a one-way component 42 and a driven component 43; the gear ring 41 is rotatably connected to the lifting groove 101, and the rack 33 can mesh with the gear ring 41; a plurality of ratchets are circumferentially arranged on the inner side of the gear ring 41; one end of the one-way component 42 is coaxially rotatably connected to the lifting groove 101, and the other end is arranged on the outer side of the filter box 10 and connected to the driven component 43; the ash pressing component 6 is connected to the driven component 43 and can drive the ash pressing component 6 to reciprocate. Preferably, during the ascent of the rack 33, its bottom end can continue to slide after leaving the meshing state with the gear ring 41, thereby extending the time for the ash receiving plate 2 to dump the ash, and reducing the possibility of manipulating the ash receiving plate 2 to reset before the dust is completely dumped.

[0031] In other schemes, the one-way component 42 includes a driving turntable 421, a rotating connecting rod 422, a driven turntable 423 and a pawl assembly 424; the driving turntable 421 is rotatably connected to the lifting slot 101 and is coaxially located in the gear ring 41; one end of the rotating connecting rod 422 is coaxially fixedly connected to the driving turntable 421, and the other end passes through the filter box 10 and is coaxially fixedly connected to the driven turntable 423; the pawl assembly 424 is rotatably arranged on the driving turntable 421, and the descent of the rack 33 can unidirectionally drive the driving turntable 421 to rotate forward through the gear ring 41, and the driven assembly 43 is connected to the driven turntable 423. Specifically, when the rack 33 rises, the rotation of the gear ring 41 causes the pawl assembly 424 to reciprocate and cannot drive the driving turntable 421 to rotate, and when the rack 33 descends, the rotation of the gear ring 41 causes the pawl to drive the driving turntable 421 to rotate together.

[0032] In other embodiments, the pawl assembly 424 includes a pawl shaft 4241, a pawl body 4242 and a torsion spring 4243; the pawl shaft 4241 is vertically arranged on the active turntable 421, the pawl body 4242 is rotatably arranged on the pawl shaft 4241, and is connected to the active turntable 421 through the torsion spring 4243.

[0033] In other embodiments, the driven assembly 43 includes a driving connecting rod 431 and a driven connecting rod 432; the driving connecting rod 431 is fixed on the driven rotating disk 423, one end of the driven connecting rod 432 is connected to the driving connecting rod 431, and the other end is connected to the ash pressing assembly 6. It should be understood that the driven rotating disk 423, the driving connecting rod 431, the driven connecting rod 432 and the ash pressing assembly 6 can be approximately regarded as a crank slider mechanism.

[0034] In other embodiments, the ash pressing assembly 6 includes an ash pressing plate 61, an ash pressing connecting rod 62 and a connecting rod 63; the ash pressing plate 61 is slidably disposed in the collection box 5, one end of the ash pressing connecting rod 62 is fixedly connected to the ash pressing connecting rod 62, and the other end passes through the filter box 10 and is connected to the connecting rod 63, and the connecting rod 63 is hinged to the driven connecting rod 432. Specifically, a through hole corresponding to the size of the ash pressing connecting rod 62 is provided on the filter box 10, so that the ash pressing connecting rod 62 can just pass through. Preferably, the filter box 10 is provided with a door that can be opened and closed at the collection box 5, and the collection box 5 can be laid flat toward the door side, so that the collected ash can be cleaned.

[0035] In other schemes, a sliding sleeve 7 and a spring 8 are further provided; a connecting rod 63 is slidably connected in one end of the sliding sleeve 7, and an ash pressing connecting rod 62 is fixedly provided at the other end, and the ash pressing connecting rod 62 is connected to the connecting rod 63 through the spring 8. The variable stroke of the connecting rod 63 is increased by the spring 8 and the sliding sleeve 7, so as to prevent excessive dust in the collection box 5 from affecting the rotation of the gear ring 41.

[0036] In other schemes, a brush 21 is provided on one side of the dust receiving plate 2 close to the filter plate 13. The dust on the filter plate 13 can be cleaned by the brush 21.

[0037] The air pollution purification device for easily compressible dust can compress the collected dust after dumping the accumulated dust without the need for additional manipulation of the dust squeezing action.
