Detailed Description

Embodiments of the present invention are described in further detail below with reference to the accompanying drawings.

Wherein the reference numerals are: the garbage can comprises a garbage bag T, a garbage can body 1, an annular groove 1a, an air suction hole 1b, a channel 1c, a plastic pressing ring 2, a ring opening 2a, a clamping groove 21, an annular convex ring 22, an air suction device 3, an air cylinder 31, a supporting frame 311, a piston 32, an air exhaust hole 32a, a connecting rod 33, a manual rod 34, a diaphragm 35, an air suction pipe 4 and a one-way valve 5.

Fig. 1 to 5 are schematic structural diagrams of the present invention. As shown in the figure, the utility model provides a can fix garbage bin of disposal bag, this garbage bin includes garbage bin body 1, and garbage bin body 1's inner chamber is used for the disposal bag that the plastic of suit made in order to make things convenient for the collection transportation of rubbish. When the garbage bag is placed in the garbage can in the prior art, the garbage bag is difficult to unfold in the garbage can, and at the moment, the periphery of the garbage bag can be tightly attached to the inner wall of the garbage can only by stretching the hands of people for continuous arrangement, so that the garbage can is not sanitary. When the traditional garbage can is used, the bag opening of the garbage bag can be directly turned over on the can opening of the garbage can, so that when people throw garbage, the garbage bag can fall into the garbage can under the driving of the garbage, and the purpose of packaging and collecting the garbage cannot be achieved.

The utility model discloses a garbage bin body 1 has set plastics clamping ring 2, and plastics clamping ring 2 is an annular structure's circle, and its shaping has opening draw-in groove 21 down, and draw-in groove 21 can just in time clamp the cooperation with garbage bin body 1's last border that also is the bung hole border of garbage bin, just so can utilize plastics clamping ring 2 to seal the sack of disposal bag T and compress tightly the bung hole of fixing at the garbage bin, makes the upper end of disposal bag T fixed to prevent that disposal bag T from being brought into the bucket by rubbish. The plastic pressing ring 2 tightly presses and fixes the garbage bag T in a sealing manner, so that a closed space is formed between the outer wall of the garbage bag T and the inner wall of the garbage can body 1. In order to prevent the released garbage from polluting the plastic clamping ring 2 and ensure the sanitation of the plastic clamping ring 2, the left end part of the utility model shown in figure 5 shows that the best press mounting method of the T bag opening of the garbage bag is as follows: the opening of the garbage bag T penetrates out of the opening 2a of the plastic pressing ring 2 from bottom to top, then turns outwards, and is pressed in the clamping groove 21 of the plastic pressing ring 2 after being folded back around the plastic pressing ring 2.

The utility model discloses install air exhaust device 3 on the outer peripheral face of garbage bin body 1. The air extractor 3 is used for evacuating the air in the closed space formed between the garbage bag T and the garbage can body 1. Because the air between the garbage bag T and the garbage can body 1 is evacuated, the periphery of the garbage bag T is tightly attached to the inner wall of the garbage can body 1 under the action of negative pressure, and therefore the purpose of unfolding the garbage bag in the garbage can is achieved.

In order to better improve the tightness of the compression of the plastic pressing ring 2, a concave annular groove 1a is formed on the top surface of the upper edge of the garbage can body 1, and an annular convex ring 22 clamped in the annular groove 1a is formed in the clamping groove 21. In order to ensure that the clamping groove 21 can be smoothly clamped into the upper edge of the garbage can body 1, the clamping groove 21 is formed with a tapered guide inclined plane with a gradually enlarged opening. Similarly, in order to smoothly snap the annular protrusion ring 22 into the annular groove 1a, the front end of the annular protrusion ring 22 is formed with an arc-shaped lead-in surface.

The utility model discloses an it has the aspirating hole 1b that is used for conveniently bleeding to open on garbage bin body 1's the bottom plate, and air exhaust device 3 is connected with exhaust tube 4, and this exhaust tube 4 is linked together with aspirating hole 1b, is provided with check valve 5 in the aspirating hole 1 b. The check valve 5 serves as a one-way blocking function, and its purpose is to prevent the drawn air from flowing back into the trash can body 1.

In the embodiment, a channel 1c which is radially arranged and communicated with the pumping hole 1b is formed on the inner surface of the bottom plate of the garbage can body 1. The function of the channel 1c is to ensure the smoothness of air extraction.

The air extractor 3 of the utility model is composed of an air cylinder 31, a piston 32, a connecting rod 33 and a manual rod 34. As can be seen from FIG. 5, the piston 32 is air-tightly slidably disposed in the air cylinder 31, and the manual lever 34 is pivotally hinged to the support frame 311 of the air cylinder 31, so that the manual lever 34 forms a lever that moves the piston 32 up and down. The upper end of the link 33 is connected to the short back of the manual lever 34, and the lower end of the link 33 is connected to the piston 32. Thus, when the long back of the manual lever 34 is pressed or lifted, the manual lever 34 is rotated about the hinge point, thereby pulling the piston 32 through the link 33. The bottom of the air cylinder 31 is provided with a connecting nozzle, and the air exhaust pipe 4 is connected on the connecting nozzle to realize the communication between the air exhaust device 3 and the air exhaust hole 1 b.

In the embodiment, the piston 32 is formed with a vent hole 32a, and a diaphragm 35 forming a one-way air valve in cooperation with the piston 32 is attached to an upper surface of the piston 32. The diaphragm 35 functions to seal the discharge hole 32a when the piston 32 ascends in the suction state and to open the discharge hole 32a when the piston 32 descends in the discharge state.

Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
