Example 1
As shown in fig. 1, the air duct structure for a trash can of this embodiment mainly includes two parts, one part is a groove 10 integrally formed on a can body 20 of the trash can, and the other part is an air duct cover plate 11 formed independently, and when the air duct cover plate 11 covers the groove 10 on the can body 20, the two parts are in contact and butt joint and fixed together.
The air duct cover plate 11 is fixed with the barrel body 20. Compared with the existing mode of directly using pipelines, the air channel in the embodiment is formed by covering the air channel cover plate 11 on the groove 10 on the barrel body 20, a special fixed connection structure does not need to be arranged aiming at the pipelines, and the air channel cover plate 11 and the barrel body 20 are easily fixed together; in addition, the air duct is provided with two parts, is suitable for the injection molding integrated forming process, and gives consideration to the production efficiency and quality of products.
In a preferred embodiment, the air duct cover plate 11 and the trash can body 20 are provided with screw holes 12, and the air duct cover plate and the trash can body are detachably fixed together by screws (not shown).
In order to improve the sealing effect of the joint between the air duct cover plate 11 and the garbage can body 20, the joint is further provided with a sealing ring 13.
Referring to fig. 2, the air duct structure may be formed to include two portions, an air inlet duct 14 and an air outlet duct 15, wherein:
one end of the air inlet channel 14 is communicated to the outside of the garbage can, the air inlet channel 14 can be further extended in a connecting mode as required to be used as an inlet of dust-air mixed gas, and the other end of the air inlet channel 14 is used for being connected with a filtering mechanism 16 arranged in the garbage can;
one end of the air discharge duct 15 is also used for connection with a filtering mechanism 16 provided in the trash can, and the other end of the air discharge duct 15 is used for connection with a suction device 17 provided in the trash can.
The filter means 16 and the suction device 17 are not a modification of the present invention and can be implemented with reference to the prior art. When the suction device 17 is in operation, the dust-air mixture enters the filter mechanism 16 from the inlet 14, and the air is sucked and exhausted by the suction device 17 through the filter mechanism 16 via the exhaust passage 15.
Correspondingly, the barrel 20 is provided with a first groove 101 and a second groove 102, and is configured with a first air duct cover plate 111 and a second air duct cover plate 112, the first air duct cover plate 111 is in butt joint with the first groove 101 to form the air inlet duct 14, and the second air duct cover plate 112 is in butt joint with the second groove 102 to form the air outlet duct 15.
As shown in fig. 3, as a preferred embodiment, the middle portions of the first and second duct cover plates 111 and 112 are both protruded outward, so that the inner sidewalls thereof form a groove-shaped structure, and when the two groove-shaped structures are butted with the two grooves on the barrel 20, an air duct with a larger cross section is formed.
Further, a plurality of through holes 103 are further formed in the second groove 102 of the bin body 20, and the inner space of the bin body 20 is communicated with the air duct, so that the suction device 17 can also suck the inner space of the bin body 20, and a negative pressure state is maintained outside a garbage bag laid in the garbage bin.
As an alternative embodiment, an inner barrel 21 may be further disposed in the body 20 of the trash can for laying trash bags. Wherein, the inner barrel 21 may be further opened with an air vent 210 so that the suction device 17 may also suck the inner space of the inner barrel 21. Based on the negative pressure environment: when the bag is paved, the air between the garbage bag and the inner barrel is pumped out, and the garbage bag is attached to the inner wall of the inner barrel 21: when dust is sucked, since the outer side of the inner barrel 21 is communicated with the suction device 17 through the through holes in the second groove 102, negative pressure can be formed at the outer side of the garbage bag laid in the inner barrel 21, so that the garbage bag is tightly attached to the inner wall of the inner barrel 21 all the time.
The suction device 17 is disposed in the body 20 of the trash can, and in order to facilitate connection of the air duct with the suction device 17, the length of the air outlet duct 15 is shorter than that of the air inlet duct 14, and correspondingly, the length of the second air duct cover plate 112 and the second groove 102 is shorter so as to facilitate connection with the suction device 17.
Further, a tubular joint 113 is integrally connected to one side of the lower portion of the second duct cover 112 for connecting with the suction device 17.
Referring to fig. 4, the relative positions shown in the drawing are taken as references, as a preferred embodiment, the first air duct cover 111 is located on the left side, the second air duct cover 112 is located in the middle, the suction device 17 is located on the right side of the lower portion of the second air duct cover 112, and the two air duct covers and the suction device are arranged in parallel from left to right, so that the structure is compact. The joint 113 of the cylindrical structure is disposed at the right side of the lower portion of the second duct cover 112, so as to be connected with the suction device 17.
Further, the tub 20 is provided with a sidewall having a thicker thickness at an upper portion than at a lower portion thereof to form a thick rim portion 201, and it is apparent that the thick rim portion 201 is outwardly protruded at an outer side of the sidewall. In order to facilitate the connection between the air duct and the filtering mechanism 16 on the trash can, two through holes 202 are provided on the thick edge portion 201, and the through holes correspond to the first and second grooves 101 and 102. When the first air duct cover plate 111 is butted with the first groove 101, the upper end of the first air duct cover plate 111 abuts against the lower side of the thick edge portion 201, and meanwhile, an air inlet duct 14 formed by butting the first air duct cover plate 111 and the first groove 101 is communicated with one through hole 202 on the thick edge portion 201. Similarly, the upper end of the second air duct cover plate 112 also abuts against the lower side of the thick edge portion 201, and the air exhaust duct 15 formed by abutting the second air duct cover plate 112 and the second groove 102 is communicated with the other through hole 202 on the thick edge portion 201.
In the height direction, the height of the thick edge portion 201 on the sidewall of the barrel body is set according to needs, preferably, compared with the length of the air inlet duct 14, the height is smaller, and the length of the through hole 202 formed in the thick edge portion 201 corresponds to the height of the thick edge portion 201, so that the length of the two through holes 202 formed in the thick edge portion is shorter, the barrel body is suitable for an injection molding process, and the difficulty of the injection molding process due to the overlong length of the through hole 202 is avoided.
Furthermore, a connecting edge 203 protruding outward is integrally connected to the lower portion of the sidewall on the same side wall with the thick edge portion 201 on the barrel body, a through hole 204 is also formed in the connecting edge 203 at a position corresponding to the first groove 101, and the through hole 204 is used for connecting with a dust suction inlet or a dust suction head of a trash can. When the first air duct cover plate 111 is butted with the first groove 101, the lower end of the first air duct cover plate 111 abuts against the connecting edge 203, so that the through hole 204 on the connecting edge 203 is communicated with the air inlet passage 14.
In a preferred embodiment, the first and second duct cover plates 111, 112 are also integrally formed. Two sealing rings 13 are correspondingly arranged at the connection part between the two air duct cover plates and the garbage can body 20 of the garbage can, and the shapes of the sealing rings are matched with the contact connection positions of the first air duct cover plate 111, the second air duct cover plate 112 and the garbage can body 20.
