the filtering component is arranged in the box body and comprises a filtering net which is an elastic piece, the two ends of the filtering net are respectively an inner end part and an outer end part, the outer end part of the filtering net is hinged to the box body, and the outer end part of the filtering net is connected with the box body through a first elastic piece; the inner end part of the filter screen is arranged on the box body and can slide along a first direction, the inner end part of the filter screen is positioned at an initial position in an initial state, and the inner end part of the filter screen slides to a limit position along the first direction under the action of wind power when the filter screen is blocked; the cleaning assembly is arranged at the outer end part of the filter screen, the cleaning assembly guides wind power blowing to the outer end part of the filter screen to blow in parallel along the surface of the filter screen in the process that the inner end part of the filter screen moves from an initial position to a limit position, and the cleaning assembly cleans the surface of the filter screen when the inner end part of the filter screen moves to the limit position; the cleaning assembly comprises a wind shield, a sliding block, a second elastic piece and a third elastic piece, the sliding block is slidably mounted on the outer side of the filter screen and is connected with the box body through the second elastic piece, one end, close to the inner end part of the filter screen, of the sliding block is the inner end part of the sliding block, and one end, far away from the inner end part of the filter screen, of the sliding block is the outer end part of the sliding block; the wind shield is slidably mounted on the sliding block, the wind shield and the sliding block are connected through a third elastic piece and a fourth elastic piece, the third elastic piece enables the wind shield to be located at the outer end part of the sliding block, and the fourth elastic piece enables the wind shield to be perpendicular to the sliding block; the wind shield is positioned on the windward side of the filter screen and is vertical to the filter screen before driving the sliding block to slide to a first preset position along the filter screen; one side of the wind shield facing the inner end part of the filter screen is the inner side surface of the wind shield, and the side of the wind shield far away from the inner end part of the filter screen is the outer side surface of the wind shield; a scraper is arranged in the wind shield, is slidably mounted on the wind shield and is connected with the wind shield through a fifth elastic piece, and the fifth elastic piece enables the scraper to extend out of the wind shield; when the wind shield is positioned at the outer end part of the sliding block, the scraper plate is pushed by the sliding block to contract into the wind shield so that a gap is formed between the wind shield and the filter screen, and when the wind shield slides to the inner end part of the sliding block, the scraper plate extends out of the wind shield under the action of the fifth elastic part and is abutted against the windward side of the filter screen; the end part of the wind shield is provided with an elastic bulge, the inner wall of the box body is provided with a limiting groove and a sliding channel, the limiting groove is positioned at a position corresponding to the outer end part of the filter screen, and the elastic bulge blocks the wind shield to slide along the sliding block under the limitation of the limiting groove; when the inner end part of the filter screen moves to the limit position, the filter screen is in a blocking state, the sliding channel is aligned with the position corresponding to the filter screen in the blocking state, and the sliding channel is communicated with the limiting groove so as to allow the elastic bulge to enter the sliding channel from the limiting groove when the inner end part of the filter screen moves to the limit position, and further allow the wind shield to slide along the sliding block; a guide inclined plane is arranged at a second preset position of the sliding channel, and the elastic bulge is pushed back into the wind shield by the guide inclined plane after moving to the second preset position; the two filter screens are symmetrically arranged along the central line of the box body; the two cleaning components are respectively arranged at the outer end parts of the two filter screens; the wind shield and the sliding block can slide and can rotate around a second axial direction to be connected, the part, close to the inner end part of the sliding block, of the contact surface of the wind shield and the sliding block is a straight surface so as to prevent the wind shield from rotating towards the direction close to the inner end part of the sliding block, and the part, far away from the inner end part of the sliding block, of the contact surface of the wind shield and the sliding block is an arc surface so as to allow the wind shield to rotate towards the direction close to the inner end part of the sliding block; the deep bead of two clean subassemblies is the butt when sliding to first preset position along the filter screen separately to rotate around the second axial when further sliding along the filter screen under the wind-force effect and keeping away from filter screen tip direction, and then make the scraper blade clean to filter screen tip, and reduce the effort of deep bead to the filter screen under the wind-force effect.
2. A smoke filter according to claim 1, wherein: one side of the sliding block, which is close to the scraper, is provided with a wedge block, and one surface of the wedge block, which faces the inner side of the filter screen, is an inclined surface; when the wind shield returns to the outer end part of the sliding block under the action of the third elastic part, the scraping plates are driven to move synchronously, and the scraping plates are pushed down by the inclined plane of the wedge block to be retracted into the wind shield.
3. A smoke filter according to claim 1, wherein: the bottom of the box body is provided with a dust collecting groove, the dust collecting groove is located on the windward side of the filter screen, and the filter screen returns to the initial position under the action of the first elastic piece to push scraped dust to the dust collecting groove.
4. A smoke filter according to claim 1, wherein: be provided with the adsorption plate in the box, the adsorption plate is located the leeward side of filter screen, and the adsorption plate further filters the air that passes through the filter screen.
5. A smoke filter according to claim 1, wherein: the second elastic piece is a tension spring, the third elastic piece is a compression spring, and the stiffness coefficient of the second elastic piece is larger than that of the third elastic piece.
6. A moxibustion device is characterized in that: a smoke filter comprising a smoke filter according to any one of claims 1 to 5 and further comprising a burner head for burning the moxa column, a smoke exhaust pipe for conveying smoke generated at the burner head to a smoke collection box; the smoke collecting box is communicated with the air inlet side of the box body.
