[0026] Example 1

[0027] like Figure 1 As shown:

[0028] A smoke and air duct for preventing smoke and ash accumulation comprises a smoke duct body 1 and a filter box 2 fixed on the surface of the smoke duct body 1.

[0029] In this embodiment: the existing disclosure (announcement) number: CN215113999U discloses a smoke and air duct steel structure; in order to solve the technical problems existing in this prior art, such as the above background technology disclosure that "the filter screen filters the particulate impurities in the flue gas. When used for a long time, the particulate impurities will block the filter screen, which will affect the ventilation effect of the smoke and air duct, and the filter screen needs to be disassembled, which is troublesome to operate. During disassembly, the impurities on the filter screen are easy to fall and accumulate at the bottom of the smoke and air duct, thereby reducing the cross-sectional area of ​​the flue, affecting the smoke circulation, and having low practicality". In terms of combined use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a filter component 3 and a cleaning component 4 are added to the present application document.

[0030] More specifically:

[0031] like Figure 1-Figure 4 As shown:

[0032] In combination with the above content, the filter assembly 3 includes a filter screen 34 installed inside the filter box 2, a reciprocating screw 36 connected to the inside of the filter box 2 by rotation, and a fixed block 37 screwed on the surface of the reciprocating screw 36. The side of the fixed block 37 is rotatably connected to a fixed rod 32 through a bearing, and a cleaning roller 33 is fixedly connected to the surface of the fixed rod 32 close to the filter screen 34.

[0033] In the present embodiment: when the smoke and air duct is in use, the particulate impurities inside the smoke and air duct can be filtered and blocked by the filter 34. When it is necessary to clean the impurities on the surface of the filter 34, the reciprocating screw 36 is driven to rotate by starting the motor 35, and then the reciprocating screw 36 drives the fixed block 37 to move back and forth, and then the cleaning roller 33 is driven to move back and forth on the surface of the filter 34 through the fixed rod 32, and the impurities on the surface of the filter 34 are cleaned by the cleaning roller 33. The impurities on the surface of the filter 34 can be cleaned without disassembling the filter 34, thereby preventing impurities from accumulating on the surface of the filter 34 and affecting the ventilation effect of the smoke and air duct.

[0034] Going further:

[0035] like Figure 1-Figure 4 As shown:

[0036] In order to improve the cleaning effect of the filter screen 34, in an optional embodiment: the top end of the reciprocating screw rod 36 is fixedly connected to the motor 35, and the output end of the motor 35 is fixedly connected to the reciprocating screw rod 36; the surface of the fixed rod 32 is symmetrically fixedly connected with a gear 310, and the side of the filter box 2 away from the filter screen 34 is fixedly connected with a tooth plate 38, and the gear 310 and the tooth plate 38 are meshingly connected; the side of the filter box 2 away from the reciprocating screw rod 36 is fixedly connected with a slide bar 31, and the fixed rod 32 is slidably connected to the slide bar 31 through a slider; the side of the filter box 2 close to the tooth plate 38 is fixedly connected with a baffle plate 39, and a movable groove is provided on the side of the baffle plate 39 close to the fixed rod 32.

[0037] In this embodiment: during the reciprocating movement of the fixed rod 32, the fixed rod 32 will drive the gear 310 to roll on the surface of the tooth plate 38, thereby driving the cleaning roller 33 to rotate, and the rotation direction of the cleaning roller 33 is opposite to the movement direction, which can improve the cleaning effect of the cleaning roller 33 on impurities on the surface of the filter screen 34. At the same time, the movement of the fixed rod 32 will slide on the surface of the sliding rod 31, and the sliding rod 31 is limited to improve the stability of the movement of the fixed rod 32. A moving groove matching the fixed rod 32 is opened inside the baffle 39, which can reduce the entry of smoke and dust into one side of the reciprocating screw rod 36 and increase the service life of the reciprocating screw rod 36 and the fixed block 37.

[0038] It should be noted that the motor 35 is electrically connected to the external power supply through a wire.

[0039] More specifically:

[0040] like Figure 1-Figure 4 As shown:

[0041] In combination with the above content, a cleaning assembly 4 is provided on the bottom surface of the filter box 2, and the cleaning assembly 4 includes a collecting box 41 fixedly connected to the bottom surface of the filter box 2, a collecting box 42 installed inside the collecting box 41, and limit blocks 43 symmetrically arranged on both sides of the collecting box 41, and a screw 44 is screwed inside the limit block 43, and the screw 44 is rotatably connected to the surface of the collecting box 41; a limit groove matching the collection box 42 is provided on one side of the limit block 43 close to the collection box 42.

[0042] In this embodiment: the particulate impurities cleaned by the cleaning roller 33 will fall into the collection box 42 due to gravity. When the impurities in the collection box 42 need to be cleaned, the limit block 43 is driven to move to the side away from the collection box 42 by rotating the screw 44, and the limit of the collection box 42 by the limit block 43 is released. The collection box 42 can be taken out from the collection box 41, and the impurities in the collection box 42 can be cleaned. When the collection box 42 needs to be installed, the collection box 42 is pushed to slide into the collection box 41, and then the screw 44 is reversed to drive the limit block 43 to move to one side of the collection box 42, and the side of the limit block 43 close to the collection box 42 is an inclined surface. When the limit block 43 moves, it will squeeze the collection box 42 and fit it tightly to the collection box 41, thereby improving the sealing effect of the installation of the collection box 42.

[0043] Working principle: When the smoke and air duct is in use, the particulate impurities inside the smoke and air duct can be filtered and blocked through the filter 34. When it is necessary to clean the impurities on the surface of the filter 34, the reciprocating screw 36 is driven to rotate by starting the motor 35, and then the reciprocating screw 36 drives the fixed block 37 to move back and forth, and then the cleaning roller 33 is driven to move back and forth on the surface of the filter 34 through the fixed rod 32, and the impurities on the surface of the filter 34 are cleaned by the cleaning roller 33. The impurities on the surface of the filter 34 can be cleaned without disassembling the filter 34. During the reciprocating movement of the fixed rod 32, the fixed rod 32 drives the gear 310 to roll on the surface of the tooth plate 38, thereby driving the cleaning roller 33 to rotate, and the rotation direction of the cleaning roller 33 is opposite to the movement direction, which can improve the cleaning roller 33 on the filter The cleaning effect of impurities on the surface of 34, the granular impurities cleaned by the cleaning roller 33 will fall into the inside of the collection box 42 due to gravity. When the impurities in the collection box 42 need to be cleaned, the limit block 43 is driven to move to the side away from the collection box 42 by rotating the screw 44, and the limit of the collection box 42 by the limit block 43 is released, and the collection box 42 can be taken out from the collection box 41 to clean the impurities in the collection box 42. When the collection box 42 needs to be installed, the collection box 42 is pushed to slide into the collection box 41, and then the screw 44 is reversed to drive the limit block 43 to move to one side of the collection box 42, and the side of the limit block 43 close to the collection box 42 is an inclined surface. When the limit block 43 moves, it will squeeze the collection box 42 and the collection box 41 tightly, thereby improving the sealing effect of the installation of the collection box 42.
