The invention discloses a bucket cover for a multifunctional intelligent trash bucket. An arc-shaped trash drop inlet is formed in the front upper portion of the bucket cover, baffle plate guide grooves are symmetrically formed in both sides of the trash drop inlet on the bucket cover, and an elastic baffle pate for blocking the trash drop inlet is slidably mounted between the two baffle plate guide grooves on two sides; a pyroelectric sensor for detecting whether a user is in proximity is installed on the upper portion of the front side of an outer tub; the lower end of a filter installing cavity is connected with an air suction pipe communicated with the filter installing cavity, and the lower end of each air suction pipe is connected with a fan; the lower end of an inner tub is integrally connected with a lower support seat, and an exhaust pipe in sealing inserting connection with the lower end of the fan is formed on the upper end of the rear side of the lower support seat; when the pyroelectric sensor detects that the user approaches, the fan works, the elastic baffle plate moves down to make the trash drop inlet open, and a user cannot smell trashes during the process of throwing the trashes.

The invention discloses a multifunction domestic garbage can. The multifunction domestic garbage can comprises an outer can, a cylindrical inner can mounted in the outer can, and a can cover arrangedat the upper end of the outer can in a sleeving mode; the lower end of the inner can is integrally connected with a lower support matched with the inner periphery of the outer can in shape, two fans are mounted at the upper end of the rear side of the lower support, and fan mounting openings are formed in the positions, provided with the fans, of the lower support; exhaust outlets are formed in the lower end of the rear wall surface of the outer can; an arc-shaped garbage throwing-in opening is formed in the upper-front part of the can cover, baffle guiding grooves are symmetrically formed inthe positions, on the two sides of the garbage throwing-in opening, of the can cover, and an elastic baffle used for blocking the garbage throwing-in opening is slidably mounted between the two baffleguiding grooves in the two sides; and a pyroelectric sensor used for detecting whether a user gets close to the domestic garbage can or not is mounted on the upper part of the front side of the outercan. When the pyroelectric sensor detects the situation that the user gets close to the domestic garbage can, the fans work, then the elastic baffle moves downwards to enable the garbage throwing-inopening to be opened, and in this way, undesirable odors of garbage are not smelt by the user in the process that the user throws the garbage.

The invention discloses a domestic intelligent trash can comprising an outer barrel, a cylindrical inner barrel installed in the outer barrel, and a barrel cover arranged at the upper end of the outerbarrel in a sleeving manner. An arc-shaped trash thrown-in opening is formed in the upper front portion of the barrel cover. Baffle guide grooves are symmetrically formed in the portions, located onthe two sides of the trash throw-in opening, on the barrel cover. An elastic baffle used for sealing and blocking the trash throw-in opening is installed between the two baffle guide grooves in the two sides in a sliding manner. A pyroelectric sensor used for detecting whether there is a user approaching or not is installed on the upper portion of the front side of the outer barrel. The lower endof a filter installation cavity is connected with gas extraction barrels communicating with the filter installation cavity. The lower end of each gas extraction barrel is connected with a fan. The lower end of the inner barrel is integrally connected with a lower support. Exhaust barrels connected with the lower ends of the fans in a sealed and inserted manner are formed at the upper end of the rear side of the lower support. When the pyroelectric sensor detects that the user approaches, the fans work, the elastic baffle then moves downwards to open the trash throw-in opening, and in this way,the user cannot smell the odor of trash in the trash throwing process.

The invention discloses a domestic garbage can. The domestic garbage can comprises an outer can, a cylindrical inner can mounted in the outer can, and a can cover arranged at the upper end of the outer can in a sleeving mode; an arc-shaped garbage throwing-in opening is formed in the upper-front part of the can cover, baffle guiding grooves are symmetrically formed in the positions, on the two sides of the garbage throwing-in opening, of the can cover, and an elastic baffle used for blocking the garbage throwing-in opening is slidably mounted between the two baffle guiding grooves in the two sides; a pyroelectric sensor used for detecting whether a user gets close to the domestic garbage can or not is mounted on the upper part of the front side of the outer can; the lower end of a filter mounting cavity is connected with air pumping cylinders communicating with the filter mounting cavity, and the lower end of each air pumping cylinder is connected with a fan; and the lower end of the inner can is integrally connected with a lower support, and exhaust cylinders in sealing inserted connection with the lower ends of the fans are formed at the upper end of the rear side of the lower support. When the pyroelectric sensor detects the situation that the user gets close to the domestic garbage can, the fans work, then the elastic baffle moves downwards to enable the garbage throwing-inopening to be opened, and in this way, undesirable odors of garbage are not smelt by the user in the process that the user throws the garbage.

The invention discloses a filter structure, and relates to the field of air filters. The filter structure comprises air inlet units; each air inlet unit is cylindrical; the side wall of the air inlet unit is a side filtering surface; one end of the air inlet unit is open, and a bottom filtering surface is arranged at the other end; the air inlet units are arranged in a tiling manner; a gap is arranged between two adjacent air inlet units; and filtering surfaces are arranged in the intervals close to the open ends of the air inlet units and connect the air inlet units into a whole. The filter structure is designed to have an air flow, so that the filtering area is increased, the filtering efficiency is increased, and the filtering through-put capacity per unit area is increased.
