When the residents need to throw the garbage, the upper cover 52 is firstly opened, the garbage is stacked on the turnable baffle plates 551 and 552 (the turnable baffle plates 551 and 552 are not turned over by the garbage within a certain weight range due to the design of the elastic force of the leaf spring 54), and then the governor can conveniently check the garbage; the lid 52 is then closed and the handle 592 is manually rotated, such that rotation of the handle 592 causes the drive shaft 591 to rotate and the pivotable baffle assemblies 551 and 552 to pivot about the pivot 56 via the left pull cord 571 and the right pull cord 572, overcoming the spring force of the leaf spring 54 to open the pivotable baffle assemblies 551 and 552 (as shown in FIG. 14) and allowing waste to fall into the lower tub 6. When released by a human hand, the reversible bulkhead assemblies 551 and 552 are rotated to their normally closed positions by the spring force of the leaf spring 54, and the drive shaft 591 and handle 592 are also returned to their original positions by the left pull cord 571 and the right pull cord 572. Therefore, through the cooperation of the upper cover 52 and the handle 592, no odor overflows from the lower barrel 6 during the whole garbage dumping process.

When the garbage needs to be poured out of the lower barrel body 6, the garbage in the lower barrel body 6 can be poured out only by gripping the cavity 51 by hand, lifting upwards and removing the separating device 5.

In FIG. 16, 7 is the partition means and 8 is the lower tub. The separating device 7 comprises a cavity 71, a reversible clapboard component 72, a rotating shaft 73, a tension spring 74, a pull rope 75 and a pedal 76. The reversible diaphragm assembly 72 comprises a diaphragm 721 and a sealing edge 722, and the reversible diaphragm assembly 72 is entirely positioned in the cavity 71; the cavity 71 is provided with a thread passing platform 711 and an inner platform 712, the inner platform 712 has a limiting function on the reversible clapboard component 72, and the thread passing platform 711 is used for the pull rope 74 to pass through. The rotating shaft 73 is positioned in the groove of the partition 721, and the partition 721 can move relative to the rotating shaft 73.

In fig. 16, the sealing edge 722 is compressible, the sealing edge 722 is made of foam or rubber material, the sealing edge 722 is installed on the periphery of the partition 721, and when the reversible partition assembly 72 is in the normally closed state, the sealing edge 722 is in contact with the inner wall of the cavity 71 to play a role in blocking odor.

In fig. 16, the tension spring 74 is a resilient return member, and one end of the tension spring 74 is coupled to the chamber 71 and the other end is coupled to the partition 721.

In fig. 16, the pull cord 75 and the pedal 76 constitute a foot-operated drive mechanism. The pull cord 74 is connected at both ends to the pedal 76 and the diaphragm 721, respectively, i.e., the pull cord 74 is directly connected to the reversible diaphragm assembly 72.

Fig. 17 is a partial schematic view of the section G-G in fig. 16. The illustration is after the lower tub body is removed.

In fig. 17, 71 is a cavity, 721 is a partition, 722 is a seal, 73 is a shaft, 77 is a washer, and 78 is a pin.

In fig. 17, the sealing edge 722 is installed on the outer periphery of the partition 721, and the rotating shaft 73 is located in the groove of the partition 721. The rotating shaft 73 passes through a hole in the side wall of the cavity 71, and the gasket 77 and the pin 78 are arranged at two ends of the rotating shaft 73 to axially limit the rotating shaft 73.

Fig. 18 is a schematic view of the invertible baffle assembly of fig. 16 when open.

In fig. 18, 721 is a partition plate, 73 is a rotary shaft, 74 is a tension spring, 75 is a pull rope, 76 is a pedal 76, and 8 is a lower barrel.

The working procedure of example four is as follows.

When the garbage is not thrown in, the spring force of the tension spring 74 keeps the reversible partition assembly 72 in the normally closed state (as shown in fig. 16), and the lower barrel 8 does not emit odor outwards due to the sealing effect of the sealing edge 722.

When the residents need to throw garbage, the garbage is put on the partition board 721, and the supervisors can conveniently check the garbage; then, the pedal 76 is stepped by foot, the pedal 76 moves downward, the pull cord 75 pulls the reversible partition plate assembly 72 to move, the reversible partition plate assembly 72 overcomes the elastic force of the tension spring 74, the reversible partition plate assembly 72 rotates and moves along the rotating shaft 73, the reversible partition plate assembly 72 is opened (as shown in fig. 18), and the garbage falls into the lower barrel body 8. When the feet of a person are loosened, the reversible clapboard component 72 rotates and moves along the rotating shaft 73 under the action of the tension spring 74, and returns to the normally closed state; and the pedal 76 is lifted to the home position by the pull cord 75. Therefore, the odor overflows from the lower barrel body 8 only at the moment of opening the reversible clapboard component 72, and the time for emitting the odor from the lower barrel body 8 is effectively reduced.

When the garbage needs to be poured out of the lower barrel body 8, the garbage in the lower barrel body 8 can be poured out only by gripping the cavity 71 by hand, lifting upwards and removing the separating device 7.

By combining the embodiment, when the garbage can is used, garbage is firstly placed on the turnable clapboard component, so that the garbage can be conveniently checked; for wet garbage, the time for emitting peculiar smell of original wet garbage in the lower barrel body is effectively reduced by controlling the turnable partition plate assembly, so that the peculiar smell emitted by the lower barrel body when the wet garbage is thrown is effectively reduced or even isolated.

The present invention may have other embodiments and modifications thereof in addition to the above-described embodiments.

For example, the elastic return element used in the above embodiments is a tension spring or a leaf spring, but the elastic return element may be modified to be a torsion spring, or a compression spring, or other types of elastic components.

For another example, the elastic return element of the above embodiment is directly connected to the reversible partition assembly, i.e. the elastic force of the elastic return element directly acts on the reversible partition assembly; it is of course also possible to connect the elastic return element indirectly to the pivotable diaphragm arrangement, i.e. to apply the elastic force of the elastic return element indirectly to the pivotable diaphragm arrangement, which leads to a slight increase in production costs and is technically easy to achieve.

Also for example, the arrangements of the invertible baffle assemblies of the several embodiments described above may be combined to achieve embodiments using three or more invertible baffle assemblies.

Or can be combined and replaced with each other on the basis of the technical scheme to form a new implementation mode; or to use the invention in a portion of a more complex waste bin; etc., all of which are intended to fall within the scope of the present invention and will not be described herein.
