Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Referring to fig. 1 and 2, an embodiment of the present invention provides an automatic garbage bag replacing device for an intelligent garbage can, which includes a mounting rack 1 and a garbage bag mounting hole 2 disposed on the mounting rack 1. An extension tube 3 is connected with the garbage bag mounting hole 2 in a sealing way. One end of the telescopic pipe 3 far away from the garbage bag mounting hole 2 is connected with a one-way valve 4 in a sealing way. The telescopic pipe 3 is a hose, so that the telescopic pipe is convenient to stretch. The upper end of the mounting rack 1 is provided with a garbage bag mounting hole 2. After the garbage bag is fixedly placed in the garbage bag mounting hole 2, when the telescopic pipe 3 is compressed upwards by the check valve 4, gas escapes from the telescopic pipe 3. When the one-way valve 4 moves downwards to stretch the extension tube 3, the internal pressure is lower than the external pressure, and the garbage bag can be unfolded on the tube wall of the extension tube 3 by the external air pressure.
Further, referring to fig. 1 and 2, the check valve 4 includes a housing 41 communicating with the bellows 3, a lid 42 rotatably disposed outside the housing 41, and exhaust holes 43 disposed on the housing 41, the exhaust holes 43 corresponding to the lid 42 one by one. The upper end surface of the housing 41 is connected with the telescopic pipe 3 in a sealing way. Two exhaust holes 43 are opened on the side wall of the housing 41, and a flip cover 42 is provided at a position corresponding to the exhaust holes 43. The housing 41 can only vent air from the inside to the outside. When the outside is supplied with air from the inside, the lid 42 covers the exhaust hole 43, so that the outside air cannot enter the housing 41 through the exhaust hole 43.
In particular, with reference to fig. 1 and 2, the non-return valve 4 further comprises a plurality of guide rods 44 arranged on the mounting frame 1 and penetrating the housing 41. Three guide rods 44 are uniformly distributed on the check valve 4. Both ends of the guide bar 44 are fixed to the mounting frame 1. The check valve 4 moves up and down along the guide 44.
Specifically, referring to fig. 1 and 2, the housing 41 is a triangular prism. The side of the housing 41 is provided with rounded corners 411. A driving mechanism is also connected to the one-way valve 4. The exhaust hole 43 is a circular hole. The lid 42 is detachably fixed to the housing 41. The pressure that each side of triangular prism received is the same, prevents that one side atress is too big to break, influences the use. The design of fillet 411 is safer when manual installation, and the space that occupies is also less, but the volume of formation is big, makes the inside more air that can store of casing, and the pressure differential that the exhaust formed is bigger at last. The driving mechanism drives the housing 41 to move up and down. The exhaust hole 43 is a circular hole to allow faster exhaust. The flip cover 42 is connected with the shell 41 in a snap-fit manner, so that the disassembly is convenient.
The utility model provides an automatic trade disposal bag device for intelligent garbage bin, specific working process as follows:
when the garbage in the garbage can is taken away or a new garbage bag is replaced, the garbage bag blocks the garbage bag mounting hole 2, and no garbage bag is arranged in the extension pipe 3. At this time, the extension tube 3 is in an extended state, the driving mechanism at the lower part of the one-way valve 4 starts to operate to drive the one-way valve 4 and the lower end of the extension tube 3 hermetically connected with the upper end of the housing 41 to start to move upwards along the vertical direction of the guide rod 44, at this time, the extension tube 3 starts to gradually contract, the space in the extension tube 3 is compressed, the pressure in the extension tube 3 is greater than the external atmospheric pressure, the flip cover 42 on the housing 41 is in an outward opening state, the compressed air in the extension tube 3 is discharged until the extension tube 3 is compressed to the shortest position, and then, the driving mechanism at the lower part of the housing 41 drives the housing 41 to move downwards along the linear direction, at this time, the space in the extension tube 3 gradually increases, the pressure in the extension tube 3 is smaller than the external atmospheric pressure, at this time, the turning plate 42 of the housing 41 is in an inward closing state under the influence of the atmospheric pressure, and the turning plate 42 blocks the exhaust hole 43 to prevent the external air from entering the housing 41 from the exhaust hole 43. When the driving mechanism drives the shell 41 and the extension tube 3 to move downwards continuously, when the atmospheric pressure difference between the inside and the outside of the extension tube 3 reaches a certain degree, the garbage bag on the garbage bag mounting hole 2 is sucked into the extension tube 3 and continues to spread downwards along the inner wall of the extension tube 3 along with the extension of the extension tube 3 until the extension tube 3 is in a completely extended state, the garbage bag is spread in place in the extension tube 3, and at the moment, a bag changing cycle is completed.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
