Description

Technical Field

[0001] The utility model belongs to the technical field of garbage collection, and in particular relates to a bag cutting device and a garbage bin. Background Art

[0002] In recent years, my country's waste sorting and management has continued to improve. Residential waste is now divided into at least three categories and bins: recyclables, which are typically sorted and recycled directly by cleaners; kitchen waste, which is removed from plastic bags and placed in green bins; and other waste, which is placed in black bins. Because kitchen waste can be recycled as animal feed, it cannot be thrown into green bins along with plastic bags. Instead, each garbage collector is required to place their own kitchen waste into designated bins. However, since kitchen waste is wet and prone to leakage, the outside and bottom of the garbage bags are often dirty, making it easy for garbage collectors to get their hands dirty when dumping. If garbage collectors return home after dumping the food waste, it's fine to wash their hands afterward. However, in many cases, garbage collectors drive out to run errands immediately after dumping the waste. This can affect personal hygiene, leading some garbage collectors to leave their food waste aside for cleaners to handle, increasing their workload and environmental pollution. Utility Model Content

[0003] The purpose of the utility model is to solve the above problems in the existing technology and to propose a bag cutting device that can put garbage into a garbage bin without dumping it.

DETAILED DESCRIPTION

[0022] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] like Figures 1-4 As shown, a bag cutting device includes:

[0025] The bag cutting unit 100 includes a bag cutting knife 101 , and the bag cutting knife 101 is provided with an upper cutting blade 102 and a lower cutting blade 103 ;

[0026] The connecting portion 200 is connected to the bag cutting knife 101 , and the connecting portion 200 is used to connect to the trash can 300 .

[0027] In this embodiment, the arrangement of the bag cutting portion 100 allows the owner to dump the kitchen waste without having to lift the bottom of the garbage bag with the bag opening facing downwards. Instead, the owner only needs to lift the upper end of the garbage bag and place the garbage bag on the upper cutting blade 102. Under the action of gravity of the garbage, the bottom of the garbage bag is cut by the upper cutting blade 102. Then, the upper end of the garbage bag is lifted, and the kitchen waste falls into the garbage bin 300 under the action of gravity, without dirtying the hands of the garbage dumper. In order to prevent the upper cutting blade 102 from failing to cut the garbage bag when the garbage bin 300 is placed on the upper cutting blade 102, a lower cutting blade 103 is further provided on the bag cutting portion 100. The lower cutting blade 103 can cut the garbage bag again during the lifting process, so that the garbage bag is broken more thoroughly.

[0028] Further preferably, the connecting portion 200 includes a connecting surface, and an inclined angle is formed between the upper cutting edge 102 and the connecting surface.

[0029] Specifically, the tilt angle is 45°±10°.

[0030] In this embodiment, when the upper cutting blade 102 cuts the garbage bag, the garbage in the garbage bag falls down under the action of gravity. Since the upper cutting blade 102 is just below the bag opening, the garbage in the garbage bag may fall onto the cutting blade. As an optional solution, Figure 2 As shown, the angle of the tilt is 45°, so that the garbage dropped on the bag cutting portion 100 can slide down under the action of gravity without getting stuck on the upper cutting edge 102.

[0031] Preferably, the ends of the upper cutting edge 102 and the lower cutting edge 103 are connected to each other.

[0032] Further preferably, the connection end of the upper cutting edge 102 and the lower cutting edge 103 forms a cutting edge angle 104 .

[0033] In this embodiment, the upper cutting blade 102 and the lower cutting blade 103 are integrally arranged, and the two cutting blades are respectively located on both sides of the bag cutting part 100, and the connecting end of the upper cutting blade 102 and the lower cutting blade 103 forms a protruding and sharp cutting blade corner 104. When the upper cutting blade 102 cannot cut the garbage bag and the lower cutting blade 103 is used to cut the garbage bag, if the cutting is close to the lower cutting blade 103, it may not be possible to effectively cut the garbage bag. Therefore, it is set at the cutting blade corner 104, and the garbage bag is thrown toward the cutting blade corner 104. The cutting blade corner 104 pierces the garbage bag and extends into the garbage bag, and then the garbage bag is pulled to cut the garbage bag.

[0034] It is worth mentioning that when the bag cutter is installed in the trash can 300, the entire bag cutter is completely extended into the trash can 300, that is, the bag cutter is hidden in the trash can 300, preventing the exposed bag cutter from causing scratches to the user during the process of cutting the garbage bag.

[0035] Preferably, the connecting portion 200 includes a clamping portion, which is provided with a clamping cavity with an opening at one end, and the clamping cavity is used to be clamped on the wall of the trash can 300.

[0036] In this embodiment, the bag cutting part 100 is used to cut the garbage bag, and the setting of the connecting part 200 realizes the connection between the bag cutting part 100 and the garbage can 300. The setting of the clamping cavity on the clamping part enables the clamping part to be clamped and fixed on the barrel wall of the garbage can 300, and a detachable connection is realized between the clamping part and the garbage can 300.

[0037] Specifically, the opening direction of the clamping cavity is the same as the inclined direction of the upper cutting edge 102 .

[0038] In this embodiment, an inclined angle of 45° is formed between the upper cutting blade 102 and the connecting surface of the connecting portion 200 so that garbage in the garbage bag will not remain on the upper cutting blade 102. Optionally, the opening of the engaging cavity is arranged to face the same inclined direction as the upper cutting blade 102, that is, the inclined direction of the upper cutting blade 102 faces the engaging direction of the engaging cavity. Then, when the connecting portion 200 is engaged with the trash can 300, the upper cutting blade 102 is tilted downward, so that the garbage can slide into the trash can 300 along the upper cutting blade 102. It is worth mentioning that the lower cutting blade 103 is also arranged to face downward, forming a cutting blade angle 104 with the upper cutting blade 102.

[0039] Specifically, the clamping portion includes three clamping plates 201, which are arranged and connected in sequence. The two outermost clamping plates 201 and the clamping plate 201 in the middle are vertically arranged to form a clamping cavity with an opening at one end.

[0040] It is worth mentioning that the three clip-on plates 201 are integrated.

[0041] In this embodiment, multiple clamping plates 201 are connected in sequence, and two adjacent clamping plates 201 are arranged perpendicular to each other, so that a clamping cavity is formed between the three clamping plates 201, and the bag cutting part 100 is located on the outermost clamping plate 201.

[0042] Further preferably, a connecting lock 202 is provided on the connecting portion 200 , and the connecting lock 202 is used to connect with the outer edge of the trash can 300 wall.

[0043] In this embodiment, in order to make the connection between the connecting part 200 and the trash can 300 more stable, a connecting lock 202 is additionally provided on the other outermost clamping plate 201, and a first step 301 and a second step 302 are provided on the wall of the trash can 300. The clamping part is clamped on the first step 301, and the connecting lock 202 is buckled on the second step 302.

[0044] It is worth mentioning that the length of the clamping plate 201 provided with the bag cutting portion 100 is greater than the length of the other outermost clamping plate 201 .

[0045] A trash can 300 includes the above-mentioned bag cutting device, and a first step 301 and a second step 302 are provided on the outer wall of the trash can 300. The clamping portion is clamped on the first step 301, and the connecting lock 202 is buckled on the second step 302, and a gap is provided between the first step 301 and the second step 302 and the wall of the trash can.
