The corresponding relationship between the plurality of scraping portions 420 and the air inlet holes 220 may be that one scraping portion 420 corresponds to one air inlet hole 220, or that a plurality of scraping portions 420 correspond to the same air inlet hole 220. For example, the scraper 400 may be made of a material with good elasticity, such as rubber, silicone, and the like. The plate body 410 and the plurality of scraping portions 420 may be a unitary piece.

When the range hood works, oil smoke enters the interior of the range hood main body 100 through the air inlet holes 220. A large amount of oil smoke passes through the oil baffle 210, and inevitably accumulates on the surface of the oil baffle 210 to form oil stains, especially the oil stains on the flanging 211, which are located on the side surface of the oil screen 200, are difficult to be touched during cleaning at ordinary times, are easy to cause a large amount of oil stains to accumulate, and are difficult to clean. In the lampblack absorber in this application, scraping portion 420 can insert to fresh air inlet 220 in, scraping portion 420 and turn-ups 211 contact, under the drive of removal end 310, scraping portion 420 removes along the extending direction of oil bar 210, can scrape off the greasy dirt of each department on turn-ups 211 to reach the effect of clean oil net. The greasy dirt that the oil net was scraped is pushed to the both ends of oil baffle 210 under the removal of scraper blade 400, and the both ends of oil baffle 210 can be provided with and lead oily portion, leads the greasy dirt to in the oil trap of lampblack absorber. The arrangement of the flanging 211 can improve the structural strength of the oil screen 200, and the contact area of the flanging 211 and the scraping part 420 can be increased due to the contact of the flanging 211 and the scraping part 420, so that the scraping part 420 is prevented from being damaged.

Generally, can be through removing aviation baffle 300 so that fresh air inlet 220 communicates with the outside or blocks when the lampblack absorber starts or closes, the lampblack absorber that sets up like this can realize the cleanness of oil net 200 through the removal of aviation baffle 300 when it starts or closes, and the design is more reasonable, and clean process is more convenient, and user experience is better.

Illustratively, referring to fig. 6 and 9 in combination, the width D of each of the plurality of wipers 420 is greater than the width D of the corresponding air inlet aperture 220. In this way, the scraping part 420 can press the flange 211, so that the scraping part 420 can better scrape off the oil stains on the oil bar 210, and the cleaning effect is better. In an embodiment not shown, each of the plurality of scraping portions may have the same width as the corresponding air inlet hole.

For example, the difference between the width D of each of the plurality of scraping parts 420 and the width D of the corresponding air inlet hole 220 may be less than or equal to 1mm. In this way, the degree of scraping between the scraping part 420 and the flange 211 is more moderate, and the influence on the movement of the air deflector 300 due to the excessive friction resistance between the scraping part 420 and the flange 211 is avoided. It will be appreciated that the frictional resistance between the scraper and the cuff is also related to the material of the scraper. The difference between D and D is applicable to the case where the scraping portion is made of most kinds of rubber materials. In some embodiments, for example where a more flexible material is used for the scraper portion, the difference between D and D may be greater than 1mm.

For example, referring to fig. 2 and 9 in combination, a groove 430 may be formed between adjacent two of the plurality of scrapers 420, and a groove bottom of the groove 430 may abut against the oil bar 210. The scraping part 420 can scrape oil stains on the outer surface of the oil bar 210 on the side close to the air deflector 300. It can be understood that, when the oil smoke enters the range hood through the air inlet 220, the outer surface of the oil baffle bar 210 close to the air deflector 300 and the turned-over edge 211 are in direct contact with the oil smoke. The scraping part 420 arranged in this way can scrape the outer surface of the side, close to the air deflector 300, of the oil deflector 210 and the flanging 211, so that the cleaning effect is better. Alternatively, in an embodiment not shown, the groove bottom of the groove may be spaced apart from the oil bar.

Illustratively, referring to fig. 3 and 4, a plurality of scrapers 420 may project from the cuff 211 towards the inside of the cigarette machine body 100. In this way, the scraping portion 420 can better cover the burring 211 to effectively scrape off oil stains everywhere on the burring 211. During the scraping process of the scraping part 420, the scraping part 420 has certain bending deformation, and the protrusion of the scraping part 420 towards the inner side of the cigarette machine body 100 from the turned-over edge 211 provides certain compensation for the bending deformation, namely, the scraping part 420 after the bending deformation can still completely cover the turned-over edge 211 to ensure the cleaning effect. In embodiments not shown, the inner side of the scraper portion facing the body of the machine may be flush with the cuff.

Illustratively, referring to fig. 3 and 10, each of the plurality of scraping portions 420 may include a first end 421 connected to the panel body 410 and a second end 422 protruding into the air inlet hole 220. Each of the plurality of scraping parts 420 has a gradually decreasing thickness or a constant thickness in a direction from the first end 421 to the second end 422. Thus, the scraping effect of the scraping part 420 can be prevented from being influenced by excessive deformation of the second end 422 during scraping due to the excessive weight of the second end. The thickness of the second end 422 is gradually reduced along the direction from the first end 421 to the second end 422, the force applied to the second end 422 in the scraping process is smaller, the deformation of the scraping part 420 in the scraping process can be better reduced, and the cleaning effect is ensured.

Illustratively, the thickness of the first end 421 may be between 1.5-3 mm. For example, the thickness of the first end 421 may be 1.5mm, 2mm, or 3mm, among others. In this way, the connection between the first end 421 and the plate body 410 is more stable, and the second end 422 is better supported.

Illustratively, the thickness of the second end 422 may be between 1-2.5 mm. For example, the thickness of the second end 422 may be 1.0mm, 1.5mm, or 2.5mm, among others. The thickness of the second end 422 is more moderate, and the deformation of the scraping part 420 is less likely to be caused during the scraping process, so as to ensure the cleaning effect.

For example, a plurality of the scraping parts 420 may be provided in one-to-one correspondence with the air inlet holes 220. Like this, each of a plurality of scraping parts 420 stretches into air inlet 220 and scrapes the clearance, and scraping parts 420's relative both sides all contact with turn-ups 211, has utilized scraping parts 420's structure more fully, sets up more rationally. In an embodiment not shown, there may be one air inlet hole for a plurality of scrapers. For example, two scraping parts may be correspondingly arranged in one air inlet hole, and the two scraping parts may be arranged side by side left and right, or the two scraping parts may be arranged side by side up and down.

For example, the air deflector 300 may be provided with an upper pressing plate 330 and a lower pressing plate 340, a fixing groove extending along the moving end 310 may be formed between the upper pressing plate 330 and the lower pressing plate 340, and the plate 410 may be clamped in the fixing groove. The fixing groove may fix the plate body 410 in a direction extending along the moving end 310, and the fastening effect is more excellent. Therefore, the scraper 400 is connected with the air deflector 300 more firmly in the scraping process, and the cleaning effect is prevented from being influenced by the shaking of the scraping part 420. It should be noted that the upper pressing plate and the lower pressing plate only indicate their positional relationship, that is, one is located above the plate body, and the other is located below the plate body, and cannot indicate the connection manner between the two. The upper pressure plate and the lower pressure plate can be integrated or separated. In the embodiment that the upper pressing plate and the lower pressing plate are integrated, the inner side of the integrated body is provided with a fixing groove extending along the moving end, one end of the fixing groove is closed, the other end of the fixing groove is opened, and the scraper is inserted into the fixing groove from the opened end to be fixed.

In some embodiments, with combined reference to fig. 7 and 8, upper platen 330 and lower platen 340 can be a unitary piece and fasteners can be attached to air deflection plate 300 through upper platen 330, plate 410, and lower platen 340. When the air guide plate is installed, the lower pressing plate 340, the scraper 400 and the upper pressing plate 330 are sequentially arranged on the air guide plate 300, and the fasteners sequentially penetrate through the first through holes 332 on the upper pressing plate 330, the second through holes 416 on the plate body 410 and the third through holes 341 on the lower pressing plate 340 to be connected to the air guide plate 300. Thus, the installation process is more convenient, and the fixing effect is better. For example, the air deflector 300 may include a glass outer plate 360 and an adhesive plate 370 located inside the glass outer plate 360, a plurality of blind rivet nuts 371 may be disposed on the adhesive plate 370, the first through hole 332, the second through hole 416, and the third through hole 341 correspond to the blind rivet nuts 371 one to one, the fastening member may be a screw adapted to the blind rivet nuts 371, and the screw is fixed into the blind rivet nuts 371 through the first through hole 332, the second through hole 416, and the third through hole 341.

For example, referring to fig. 7, an edge of the upper platen 330 may be provided with a plurality of first lugs 331 in one-to-one correspondence with the plurality of wipers 420, wherein each of the plurality of first lugs 331 may be pressed against an upper surface of the corresponding wiper 420. Thus, the plurality of first lugs 331 can support the corresponding scraping parts 420, reduce the deformation of the scraping parts 420 during the scraping process, and ensure the cleaning effect. Alternatively, referring to fig. 4, each of the plurality of first bosses 331 is located outside the corresponding air inlet hole 220, and each of the plurality of first bosses 331 has a width smaller than that of the corresponding scraper portion 420. The first lug 331 does not extend into the air inlet 220, so as to avoid affecting the deformation of the scraping part 420 during the scraping process, and reduce the resistance of the scraper 400 during the scraping process.

For example, referring to fig. 8, the edge of the lower press plate 340 may be provided with a plurality of second lugs 342 in one-to-one correspondence with the plurality of wipers 420, wherein each of the plurality of second lugs 342 may press against the lower surface of the corresponding wiper 420. Thus, the second lugs 342 can support the corresponding scraping parts 420, reduce the deformation of the scraping parts 420 during the scraping process, and ensure the cleaning effect. Alternatively, each of the plurality of second bosses 342 is located outside the corresponding air inlet hole 220, and each of the plurality of second bosses 342 has a width smaller than that of the corresponding scraper portion 420. The second lug 342 does not protrude into the air inlet hole 220, so as to avoid affecting the deformation of the scraping part 420 in the air inlet hole 220, and reduce the resistance of the scraper 400 in the scraping process.

Illustratively, referring to fig. 10, the plate body 410 may further have a second side 412 opposite the first side 411. The plate body 410 may include a first portion 413 proximate the first side 411 and a second portion 414 proximate the second side 412. The lower surface of the second portion 414 may be protruded downward with respect to the lower surface of the first portion 413 to form a boss 415, and the shape of the fixing groove is matched with that of the plate body 410. In this way, in the direction from the first side 411 to the second side 412, the fixing groove may limit the position of the boss 415, so as to improve the stability of the connection between the scraper 400 and the air deflector 300, prevent the scraper 400 from being released from the fixing groove, and ensure the use of the scraper 400. In an embodiment not shown, the first and second portions may have the same thickness, and the plate body has an elongated plate shape in the direction from the first side to the second side.

Illustratively, fasteners are attached to the air deflection plates 300 through the upper platen 330, bosses 415, and lower platen 340. The penetration of the fastener through the boss 415 may provide a more secure connection between the fastener and the blade 400 due to the greater thickness of the plate body 410 at the boss 415. In an embodiment not shown, the fastener may be connected to the air deflection plate through the first portion.
