Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a trash can.

2. Description of the Related Art

At present, there are various trash can structures in the art. For example, Chinese patent No. CN201120017941.8 discloses a “convenient trash can” which comprises a horizontal partition plate proximate to the bottom part of the trash can, a long slot formed in the middle of the partition plate at a lower part of the convenient trash can, a plastic trash bag roll placed below the long slot. The outmost trash bag of the trash bag roll passes through the middle part of the long slot in the middle of the partition plate and opens at an upper opening. The edge of the upper opening is turned back outwards and sleeves the edge of the upper opening of a can body. A collar clamped on the edge of the upper opening is arranged in the upper opening of the can body, and the collar is arranged outside the trash bag which sleeves the edge of the upper opening of the can body. The whole roll of trash bags are put into the trash can in advance and are used one by one, so that the trash can is simple in structure and convenient to be used. However, the trash can has the following shortcomings: because the trash bags of the trash cans are arranged at the bottom part of the can body, when one trash bag is damaged, trashes and sewage easily pollute a spare trash bag to cause waste of the trash bags. Meanwhile, the sleeving operation of the trash bag as discussed above is also very inconvenient.

SUMMARY OF THE INVENTION

One objective of the present invention is to provide a trash can which facilitates reliably storing spare trash bags in the trash can, preventing trashes and sewage from polluting the spare trash bags, and conveniently replacing the trash bag in use.

The trash can in accordance with an embodiment of the present application comprises a trash bag arranged in a can body of the trash can, a trash inlet formed in the upper part of the can body, an upper cover for sealing or opening the trash inlet, and a support frame arranged in the can body of the trash can. The trash bag is an elongated tubular trash bag. Spare trash bags are continuously stacked and then sleeve the outer side of the support frame. A trash bag in use passes through a through hole in the support frame and is arranged at the inner side of the support frame. The support frame keeps an opening part of the trash bag open. The bottom part of the trash bag is sealed in a knotting manner. When the trash bag is pulled, the elongated tubular trash bag is pulled out from the through hole in the support frame. The can body of the trash can comprises an upper-section can body and a lower-section can body. The support frame is located in the upper-section can body. The lower-section can body is provided with a door, which can be opened in a rotating manner, and a cutter for cutting the trash bag at the inner side of the door body.

The trash can in accordance with the present invention has the following advantages: 1) the spare trash bags are continuously stacked and then sleeve the outer side of the support frame so that the trash bags can be stored into the trash can; 2) the trash bag in use is located at the inner side of the support frame and can prevent the trashes from polluting the support frame; 3) because the support frame is located in the upper-section can body, the trash bag in use passes through the through hole in the support frame and is arranged at the inner side of the support frame, the spare trash bags are continuously stacked and then sleeve the outer side of the support frame, the spare trash bags are not polluted in case the trash bag of the trash can in use is damaged; 4) the support frame keeps the opening part of the trash bag open, the bottom part of the trash bag is sealed in a knotting manner, and the elongated tubular trash bag is pulled out from the through hole in the support frame when the trash bag is pulled, so that the operation of replacing the trash bag is very convenient; 5) the lower-section can body is provided with a door body which can be opened in a rotating manner, and the cutter for cutting the trash bag is arranged at the inner side of the door body, so that the trash bag is full of the trashes and the door body is opened, the elongated tubular trash bag is cut off by the cutter, and the trashes can be conveniently taken out; 6) the operation of replacing the trash bag is quickly completed after a trash bag is pulled out and its bottom part is knotted.

According to an embodiment of the present application, a pedal is arranged in the trash can for driving the upper cover to open or close through a connecting rod. Thorough this structure, the upper cover can be conveniently opened through the pedal. In the alternative, the trash can may also adopt a pedal-free structure.

According to another embodiment of the present application, an outward folded edge is arranged at the lower part of the support frame for facilitating sleeving and locating of the spare trash bags and preventing the trash bag and the spare trash bags from sliding off.

As an embodiment, an elastic cushion ring which is matched with the lower part of the support frame is arranged in the trash can. The elastic cushion ring has a buffer effect when the trash bag is pulled, and prevents the trash bag from being damaged when the trash bag is pulled.

According to yet another embodiment, the opening part of the upper-section can body is provided with a locating snap ring which comprises a locating and clamping block, and a locating hole matched with the locating and clamping block is formed in the upper-section can body.

According to a further embodiment of the present application, an inner cover is arranged in the locating snap ring, an inner cover spring compels the inner cover to seal the trash inlet, and the inner cover can further seal the trash bag and prevent an odor from leaking. In the alternative, the trash can may also adopt an inner cover-free structure.

A locking knob for locking the inner cover may be arranged in the locating snap ring, and the inner cover may be locked or arranged at a depressible position by rotating the locking knob. The trash can may also adopt a locking knob-free structure.

The trash can may be provided with a base, and the lower-section can body may be fixed on the base so that the structure is beneficial to manufacturing of the trash can.

The upper and lower rotating shafts of the door body may respectively be located on the lower part of the upper-section can body and the base. A locking mechanism matched with the side wall of the door body may be arranged on the side surface of the lower-section can body, and the door body may be conveniently opened or closed by operating the locking mechanism.

The locking mechanism comprises clamping holes and clamping hooks. The clamping holes are formed in the side wall of the door body. The clamping hooks are arranged on the side surface of the lower-section can body. A pressing slope is arranged at the front end of each clamping hook. When the pressing slope at the front end of each clamping hook is in contact with the corresponding clamping hole, the clamping hook moves and enters the corresponding clamping hole. Each clamping hook is provided with a key which is exposed outside the outer surface of the lower-section can body, and each clamping hook can move and exit from the corresponding clamping hole by pressing the corresponding key to open the door body.

The various features of novelty which characterize the invention are pointed out with particularity in the claims annexed to and forming a part of the disclosure.
