Description

Garbage compression assembly

Technical Field

The invention relates to the field of household articles, in particular to a garbage compression assembly. However, the invention is not limited to trash compaction, and can be applied to other aspects, such as the aerospace field, as an item price holding assembly to prevent the items from floating at will. For another example, the present invention is applied to clothes storage, and is used as a clothes storage component, especially a bulky garment, such as a down jacket, to reduce the volume occupied by the bulky garment.

Background

The garbage can is a common article in daily life, is a container for storing garbage, mostly adopts a barrel-shaped structure with a certain depth, and puts the garbage into the can through an opening at the top or the side of the can. When the garbage can is matched with the garbage bag for use, the interior of the garbage can be kept clean. However, most trash cans do not have a trash compaction function at present, and few people actively compact the trash because the trash bags are cheap and the trash is generally dirty. Therefore, the space utilization rate is low when loose and porous garbage such as paper rolls, packing boxes, disposable paper cups and the like are contained, the storage amount of the garbage is greatly reduced, and the garbage bag is not sufficiently utilized. The garbage bags are plastic bags which are not easy to degrade and are the main source of white pollution. Therefore, the garbage can does not compress garbage, which not only causes resource waste, but also aggravates environmental pollution.

A few existing garbage cans with the garbage compression function mostly realize garbage compression by pushing a pressing plate parallel to a top cover to move downwards.

For example, chinese patent publication No. CN106144343A discloses a trash can, comprising: staving, bung, clamp plate and hydraulic pump, staving upper surface part is formed with the rubbish chamber to downward recess, and the bung is connected with the upper surface hinge of staving, and the bung cooperatees with the staving for the bung can cover the opening of closing the staving, covers at the bung and closes under the open-ended state, and the hydraulic pump is fixed at the lower surface of bung, and the clamp plate links to each other with the piston rod on the hydraulic pump, and the piston rod can make the clamp plate follow vertical direction and move. This garbage bin overcomes among the prior art garbage bin when depositing rubbish, when the space between the rubbish is too big, the inside usage space of garbage bin can not obtain make full use of, and the volume that garbage bin deposited rubbish is far less than the problem of the rubbish volume of depositing of reality.

For another example, chinese patent document No. CN105035603B discloses a pedal-type compressible trash can, in which a compression hammering transmission device for compressing trash and a trash can liner for placing the trash are disposed in a housing, and a trash input opening and a liner removal opening are disposed on the housing; a pulley in the compression hammering transmission device is fixed at the top of the shell; the upper ends of the two side inhaul cables penetrate through the pulleys and then are connected with the compression device, and the lower ends of the two side inhaul cables are respectively connected with two ends of an inhaul cable lever; a lever fulcrum is arranged at the bottom of the shell and is positioned in the middle of the inhaul cable lever; the spring is positioned below the inhaul cable lever; the counterweight heavy hammer is arranged at the lower end of the compression device which is driven by the inhaul cable to move up and down in a telescopic way and is positioned above the opening of the inner container of the garbage can. Adopt this garbage bin can compress rubbish, improve the space utilization of garbage bin, improved the holding capacity of garbage bin, the rubbish after the compression is convenient for carry, transport.

Two problems are common to the above two kinds of trash cans, one is that when the trash is compressed, the trash compressing components are in direct contact with the trash, and in some cases, sticky trash such as toilet paper for blowing nose, trash bags for containing oil cakes, etc. may be stuck on the compressing assembly, which requires manual removal of the stuck trash, resulting in time and labor waste. Moreover, when the garbage is compressed, some liquid and semi-solid dirt may adhere to the surface of the garbage-compressing component, such as snivel, sputum, juice on fruit peel, leftover particles, etc., and although the dirt may not be easily detected by eyes, a large amount of bacteria may grow on the garbage-compressing component in the past, while the garbage-compressing component is not replaced as often as a garbage bag, is usually used for the whole life, is often cleaned, wastes labor force, and is not cleaned often, which may cause health problems for indoor personnel; secondly, the size of the opening of the garbage bag is constant, and the peculiar smell in the garbage bag is easy to be emitted outwards.

Some trash cans that compress trash have compression assemblies on the sides that compress the trash by moving the compression plates laterally.

For example, chinese patent publication No. CN203047913U discloses a lateral compression garbage can, which includes a box body, wherein at least one strip-shaped groove is formed in a side wall of the box body, and a simple compression assembly for laterally compressing garbage is disposed at a position corresponding to the strip-shaped groove on the box body. The advantages are that: the vertical compression in the prior art is changed into horizontal one-way or two-way compression of garbage, so that the structure is simple; the elastic pressing sheet can automatically rebound to the original position, and the operation is convenient. The utilization rate of the dustbin is improved, the environmental protection is facilitated, and the dustbin is easy to maintain and popularize. However, this patent has a problem in that the push rod extending outward easily comes into contact with the limbs of a person to cause the trash can to be dumped and the trash is scattered from the trash bag.

It can thus be seen that there is a significant need in the art for a waste compaction assembly that facilitates compaction of waste and reduces bacterial growth on the parts that compact the waste.

Preferably, the tub covers may be gradually closed in a manner of interlocking with each other during the process of closing the common opening. Preferably, the tub covers may be gradually opened in a manner of being interlocked with each other during the opening of the common opening.

According to a preferred embodiment, the waste compression assembly has a linkage assembly including a foot bar. Preferably, the second inner tub may be driven by the link assembly to move in the first direction to open the common opening while the foot lever is depressed. Preferably, the tray may be driven by the linkage assembly to move away from the common opening while the foot bar is depressed. Preferably, when the foot lever is depressed, the connecting rod assembly can drive the barrel cover to open.

According to a preferred embodiment, the waste compression assembly further comprises at least one resilient member connected to the linkage assembly. Preferably, an external force artificially applied to the foot bar while the foot bar is depressed is converted into elastic potential energy of the elastic member by the link assembly. Preferably, the elastic element is a return spring. Preferably, upon releasing the foot lever, the elastic potential energy of the elastic element is released and thereby drives the second inner tub to move in a second direction opposite to the first direction via the link assembly to close the common opening. Preferably, upon release of the foot lever, the elastic potential energy of the elastic element is released and thereby drives the tray via the linkage assembly in a direction towards the common opening.

Example 3

This embodiment may be a further improvement and/or a supplement to embodiments 1, 2 or a combination thereof, and repeated contents are not described again. The preferred embodiments of the present invention are described in whole and/or in part in the context of other embodiments, which can supplement the present embodiment, without resulting in conflict or inconsistency.

According to a preferred embodiment, referring to fig. 1, 2 and 3, the garbage compressing assembly may include an inner tub 100, a pedal lever 270 and a return spring 300. The return spring 300 may be used to rotationally return the foot lever 270 by an elastic force when the foot lever 270 is not subjected to an artificially applied force. The inner tub 100 may include a first inner tub 110 and a second inner tub 120 disposed inside the first inner tub 110. At least two first elastic pieces 111 may be provided at the upper portion of the first inner tub 110. The second inner tub 120 may be provided at an upper portion thereof with at least two second elastic pieces 121. The first free end 111A of each first elastic sheet 111 is fixedly connected with the second free end 121A of at least one second elastic sheet 121. When the first inner tub 110 is mounted on the outer tub 510 of the trash can, a portion of the first inner tub 110 located below the first elastic sheet 111 is fixedly connected to an inner wall of the trash can. The bottom of the inner tub 100 is formed of a tray 400 provided in the second inner tub 120. The tray 400 is slidable up and down with respect to the second inner tub 120.

Preferably, the garbage compressing assembly may further include a first link 210 and a second link 220 linked with the foot lever 270. Preferably, when the foot lever 270 is depressed, the first connecting rod 210 pushes the second inner tub 120 to move upward under the driving of the foot lever 270 and the second connecting rod 220 pulls the tray 400 to move downward under the driving of the foot lever 270. Preferably, upon releasing the foot lever 270, the first link 210 pulls the second inner tub 120 to move downward by being driven by the foot lever 270 and the second link 220 pushes the tray 400 to move upward by being driven by the foot lever 270. This rubbish compression subassembly is through crooked first flexure strip, the rubbish in the second flexure strip and flexible tray realization are compressed the disposal bag, the first flexure strip incurving in the compression rubbish in-process, the sack that drives the disposal bag on the first flexure strip of cover draws in, and tray upward movement, make the accommodation space of rubbish reduce, rubbish compression subassembly can not with rubbish direct contact in the compression process, can solve on the rubbish compression subassembly easily dirty and easily breed the problem of bacterium, moreover, rubbish compression process has utilized return spring, can need not manual or electric operation after loosening the pedal pole, convenient energy saving again promptly.

According to a preferred embodiment, referring again to fig. 1, the minimum width of the first elastic sheet 111 may be equal to or greater than the maximum width of the second elastic sheet 121. Preferably, the width of the first elastic sheet 111 is gradually increased from the first fixed end 111B to the first free end 111A of the first elastic sheet 111. Tong (Chinese character of 'tong')

By the mode, the stress condition of the first fixed end of the first elastic sheet can be improved, the stress concentration is small, and the service life of the elastic sheet is prolonged. In addition, the situation that the garbage bag is damaged or the compression effect is reduced due to mutual contact of the first free ends can be reduced in the compression process.

According to a preferred embodiment, the second elastic piece 121 may be provided with an anti-pinch member 140 for preventing the garbage bag from being pinched between the first elastic piece 111 and the second elastic piece 121.

According to a preferred embodiment, referring to fig. 4, the first free end 111A and/or the second free end 121A may be provided with an arc-shaped protrusion 130 protruding inward of the inner tub 100. Since, when there is much garbage, if the first free end and the second free end are integrally formed in a sheet shape, it is likely that large, soft and light garbage such as toilet paper and plastic packing bags on the top are caught and hung on the first free end and the second free end, and even dropped into the inner tub, causing inconvenience to the user. Therefore, the inconvenience brought to users by hanging the garbage on the top of the garbage bag on the first free end and/or the second free end or throwing the garbage bag out can be reduced.

According to a preferred embodiment, referring to fig. 6, a first brush 410 protruding obliquely upward may be provided around an upper surface of the tray 400 contacting the trash bag. When the garbage can is seated on the ground, the bristles of the first brush 410 form a contour enclosing the contour of the tray 400 in a first projection plane toward the ground. Therefore, after the tray is installed in the second inner tub, the bristles of the first brush 410 can prevent the garbage bag from being caught in the gap to be damaged or to hinder the relative movement between the first inner tub and the second inner tub.

According to a preferred embodiment, referring to fig. 7, the third free ends of the bristles of the first brush 410 may be bent. Because of the different qualities and thicknesses of the trash bags, the straightened softer bristles may also puncture some of the thinner trash bags in extreme conditions, causing the liquid of the trash bags to flow out. Thus, the third free ends of the brush staples are formed in an arc shape, so that the possibility of breakage of the garbage bag can be further reduced. For ease of viewing, a preferred embodiment of one bristle of the first brush 410 is shown only schematically in fig. 7.

According to a preferred embodiment, referring to fig. 6 and 8, the middle of the upper surface of the tray 400 is depressed downward to form an arc-shaped depression 420, and the first brush 410 is adhered to the edge of the depression 420. Through this mode to make rubbish in the disposal bag can reduce the possibility that rubbish was by the centre gripping gap to the middle part gathering as far as possible, in addition, first brush is pasted at the edge of depressed part, can directly set up first brush into the state that stretches out in the slant with the help of the edge of depressed part, simplifies the structure of first brush and sets up the degree of difficulty.

According to a preferred embodiment, the first hardness of the first elastic sheet 111 is greater than the second hardness of the second elastic sheet 121. Because the bending degree of the second elastic sheet is smaller than that of the first elastic sheet, in the process of compressing the garbage, the obstruction of the second elastic sheet to the first elastic sheet can be reduced, so that the elastic force of the return spring is converted into the acting force for compressing the garbage more, and the compression effect is better.

According to a preferred embodiment, referring again to fig. 2, the trash compression assembly may further include a can lid 520 of the trash can, a fifth link 250 for pushing the can lid 520 open and cooperating with the foot lever 270. Preferably, the opening angle α of the lid 520 opened to the limit position is an acute angle and a weight 521 is provided on the lid 520 and/or in the lid 520. Adopt a plurality of connecting rods to couple together each part, accomplish the action of uncapping and propping open the rubbish sack through stepping on a footboard action to accomplish rubbish compression and lid action voluntarily when loosening the footboard, convenient to use. When the pedal is not stepped on, the barrel cover is closed under the action of gravity and a return spring 300 to push the pedal rod 270 to drive the fifth connecting rod 250; meanwhile, under the driving of the pedal lever 270, the first connecting rod 210 drives the second inner barrel 120 to move downwards, and because the first inner barrel and the second inner barrel are fixedly connected at the top, the relative motion between the first inner barrel and the second inner barrel causes the first elastic sheet to generate bending deformation, the first elastic sheets distributed in the circumferential direction are folded, and the upper opening of the garbage bag arranged in the barrel is tightened; and the second link 220 pushes the tray 400 to ascend, thereby realizing the garbage compression process.

According to a preferred embodiment, the waste compaction assembly can further comprise at least one damping element 600. One end of the damping member 600 may be hinged to the foot lever 270. The other end of the damping element 600 may be hinged above the trash can. Preferably, a first damping coefficient of a first motion state of damping element 600, which is the motion state of damping element 600 during depression of the foot lever, is smaller than a second damping coefficient of a second motion state of damping element 600 after release of the foot lever, which is opposite to the motion direction of the first motion state.

Example 4

This embodiment may be a further improvement and/or a supplement to embodiments 1, 2, and 3 or a combination thereof, and repeated details are not repeated. The preferred embodiments of the present invention are described in whole and/or in part in the context of other embodiments, which can supplement the present embodiment, without resulting in conflict or inconsistency.

According to a preferred embodiment, referring to fig. 1 and 2, a garbage compressing assembly may include an inner tub 100, a pedal lever 270, and a return spring 300. The return spring 300 can assist the return of the foot lever 270. The inner tub 100 may include a first inner tub 110 and a second inner tub 120 nested within the first inner tub 110. At least three first elastic pieces 111 may be provided at the upper portion of the first inner tub 110. At least three second elastic pieces 121 are provided at the upper portion of the second inner tub 120. The first free end 111A of each first elastic sheet 111 is fixedly connected with the second free end 121A of at least one second elastic sheet 121. Preferably, after the second inner barrel 120 is nested in the first inner barrel 110, the first inner barrel 110 and the second inner barrel 120 may be in a clearance fit except for the fixedly connected portions of the first elastic sheet 111 and the second elastic sheet 121 at the first free end 111A and the second free end 121A. That is, the first inner tub 110 and the second inner tub 120 may relatively move with respect to each other except for the fixed portion. The first inner barrel 110 and the second inner barrel 120 may be relatively moved in the axial direction. Preferably, the free end of the foot bar 270 is provided with a pedal, and the pedal may further be provided with an anti-slip groove so that the foot applies force to the foot bar 270.

Preferably, when the garbage can is mounted on the first inner tub 110, a portion of the first inner tub 110 below the first elastic sheet 111 is fixedly connected to an inner wall of the garbage can. Preferably, the outer wall of the first inner tub 110 is provided with a mounting portion 112, and the mounting portion 112 may be detachably mounted to the inner wall of the trash tub. For example, the mounting portion 112 is a raised edge that is fastened to the inner wall of the trash can by a raised edge and/or a bolt. For another example, a boss adapted to the outer diameter of the first inner barrel 110 is disposed on the inner wall of the garbage can, the first inner barrel 110 is directly clamped at the boss, and then the first inner barrel 110 and the boss are fixedly connected by a bolt penetrating through the outer shell of the garbage can and partially extending to the body of the first inner barrel 110.

According to a preferred embodiment, the bottom of the inner tub 100 may be constituted by a tray 400 provided in the second inner tub 120. The tray 400 may slide up and down with respect to the second inner tub 120. If the bottom of the inner tub 100 is the same as that of the inner tub 100 of the general garbage can, i.e., the fixed bottom moves downward along with the downward movement of the second inner tub 120, resulting in a limited ability to compress garbage. Preferably, the central portion of the tray 400 is provided with a downwardly concave circular-arc shaped recess so that the garbage in the garbage bag can be gathered toward the central portion as much as possible.

Preferably, the edge of the tray 400 is provided with a first brush extending upward and obliquely, and the bristles of the first brush extend out of the tray 400. Accordingly, it is possible to prevent the garbage bag and/or garbage from being caught in the gap between the first and second

inner barrels

110 and 120 when the tray 400 and the second inner barrel 120 are relatively displaced, resulting in an unsmooth compression process and/or breakage of the garbage bag. It is particularly preferred that the free ends of the bristles of the first brush are arcuate. That is, the bristles are not in a straight state, and the free ends thereof are in a bent state. Although the hardness of the first brush can be preset when the garbage bag is designed, due to the different qualities and thicknesses of the garbage bag, the straightened softer bristles can pierce some thinner garbage bag in an extreme state, and the liquid in the garbage bag flows out. Thus, the possibility of breakage of the garbage bag can be further reduced by forming the free end into an arc shape. In addition, since the first brush is in direct contact with the inner wall of the second inner tub 120 during the movement, the inner wall of the second inner tub 120 can be cleaned, for example, to remove some dust and sticky contaminants.

Preferably, at least three first elastic pieces 111 are uniformly distributed along the circumferential direction of the first inner tub 110.

According to a preferred embodiment, the garbage compressing assembly may further include a first link 210 and a second link 220 linked with the foot lever 270. Preferably, when the pedal lever 270 is stepped down, the first link 210 may push the second inner tub 120 to move upward by being driven by the pedal lever 270, and the second link 220 may push the tray 400 to move downward by being driven by the pedal lever 270. Therefore, when the pedal lever 270 is stepped down, the second inner tub 120 moves upward, so that the downward pulling force of the second elastic piece 121 on the first elastic piece 111 is gradually weakened, the free ends of the first elastic piece 111 and the second elastic piece 121 are unfolded outward to form an inlet for garbage, and the tray 400 also moves downward to increase the space for accommodating garbage formed by the tray 400 and the second inner tub 120, so that more garbage can be put in. Preferably, upon releasing the foot lever 270, the first link 210 may pull the second inner tub 120 to move downward by being driven by the return spring 300 and the foot lever 270, and the second link 220 may push the tray 400 to move upward by being driven by the return spring 300 and the foot lever 270. Therefore, when the foot lever 270 is released by the foot, the second inner barrel 120 moves downward under the indirect action of the return spring 300, so that the second elastic piece 121 inside pulls the first elastic piece 111 to bend and fold toward the middle, and meanwhile, the tray 400 also moves upward under the indirect action of the return spring 300, so as to form a clamping effect on the garbage of the garbage bag, thereby improving the compression effect.

According to an alternative embodiment, the first link 210 and the second link 220 may be directly coupled to the foot bar 270 for linkage. For example, one end of the first link 210 may be hinged to the second inner tub 120, one end of the second link 220 may be hinged to the tray 400, the other end of the first link 210 may be hinged to the foot lever 270 with its hinge point and the pedal located at different sides of the first fulcrum 281 of the foot lever 270, respectively, and the other end of the second link 220 may be hinged to the foot lever 270 with its hinge point and the pedal located at the same side of the first fulcrum 281 of the foot lever 270. Thus, when the pedal is stepped on, the pedal lever 270 drives the first link 210 to push the second inner tub 120 upward and drives the second link 220 to pull the tray 400 downward.

According to another alternative embodiment, the first link 210 and the second link 220 may be indirectly coupled to the foot bar 270 to be interlocked. For example, the first refuse compression assembly may further comprise a third link 230 and a fourth link 240. One end of the first link 210 may be hinged to the second inner tub 120, and one end of the second link 220 may be hinged to the tray 400. A position between both end points of the third link 230 is hinged to the second fulcrum 282. One end of the third link 230 near the first fulcrum 281 is connected to the other end of the first link 210, and the other end of the third link 230 is connected to the other end of the second link 220. One end of the fourth link 240 is hinged to the foot lever 270, the other end of the fourth link 240 is hinged to the third link 230, and the hinge point is located between one end of the third link 230 and the second fulcrum 282. The above two alternative embodiments are only some preferred embodiments, and it is understood by those skilled in the art that the first link 210 and the second link 220 have other implementation manners linked with the pedal lever 270, so that when the pedal lever 270 is stepped down, the first link 210 can push the second inner tub 120 to move upward under the driving of the pedal lever 270, and the second link 220 can pull the tray 400 to move downward under the driving of the pedal lever 270. Or vice versa. All of which are intended to fall within the scope of the present invention.

According to a preferred embodiment, the second link 220 may be a spring lever. Preferably, the spring rod has an elastic force at least in a length direction thereof and is capable of being extended and retracted in the length direction thereof. Along with the continuous increase of rubbish volume, the tray 400 ascending space is limited, and at this moment, the second connecting rod 220 will be compressed under the effect of tray 400, makes the interior bucket 120 of second hold more rubbish in, and the elastic connection here can also guarantee that second connecting rod 220 does not react to other connecting rods so that bung 520 can't close.

According to a preferred embodiment, the width of the second elastic sheet 121 is smaller than the width of the first elastic sheet 111. Since the main function of the second elastic piece 121 is to pull the first elastic piece 111 downward to compress the garbage, the width of the second elastic piece 121 smaller than that of the first elastic piece 111 helps to reduce the influence of the reaction force of the second elastic piece 121 on the bending of the first elastic piece 111.

According to an alternative embodiment, the anti-pinch device 140 can be a second brush disposed on both sides of the second elastic piece 121. In this way, the trash bag can be prevented from being sandwiched between the first elastic piece 111 and the second elastic piece 121. Preferably, the bristles of the first brush have a first bristle hardness greater than or equal to a second bristle hardness of the bristles of the second brush.

According to another alternative embodiment, the anti-pinch element 140 may be an anti-pinch layer disposed between the garbage bag and the first elastic sheet 111, and the anti-pinch layer is attached to the second elastic sheets 121 in a tubular shape when the first elastic sheet 111 is not bent. Preferably, the upper end of the anti-pinch layer at least extends to the fixed connection point of the first elastic sheet 111 and the second elastic sheet 121, and the lower end of the anti-pinch layer extends to below the lower end of the second elastic sheet 121. Preferably, the anti-pinch layer can be an elastic rubber layer or an elastic cloth. Preferably, the anti-pinch layer is at least partially adhered to the second elastic sheet 121.

According to a preferred embodiment, the width of the first elastic sheet 111 gradually increases from bottom to top. Preferably, the maximum width of the first elastic sheet 111 is smaller than the minimum width of the first elastic sheet 111.

According to a preferred embodiment, the inner tub 100 is provided with a first viewing window 150 for viewing the position of the tray 400. Preferably, at least two first viewing windows 150 are disposed on the inner barrel 100, and the light paths of the at least two first viewing windows 150 at least partially overlap. Thus, the position of the tray can be observed more clearly. When the volume of the compressed garbage in the bin reaches the maximum, the tray 400 can be observed to descend to the lowest position through the first visual window 150, and at the moment, the pedal is stepped down to open the bin cover 520, so that the garbage bag filled with the compressed garbage can be taken out.

According to a preferred embodiment, the first window 150 is a through hole formed in the inner tub 100, for example, an oval through hole or a long bar-shaped through hole. The through holes may include first through holes on the first inner barrel 110 and second through holes on the second inner barrel 120. When the first elastic sheet 111 is in a non-bent state and the first through hole is viewed in front, the first outer contour of the first through hole coincides with the second outer contour of the second through hole or the first outer contour is at least partially enclosed within the second outer contour. Preferably, in the case that the first window 150 is a through hole, the second window may be inserted with an anti-pinch transparent sheet to prevent the garbage bag from being pinched between the first inner tub 110 and the second inner tub 120 when the first inner tub 110 and the second inner tub 120 are relatively displaced. Preferably, the inner barrel 100 may be made of a transparent material, and the first visual window 150 is a partial region of the inner barrel 100. This reduces the decrease in the mechanical properties of the inner tub 100 due to the opening of the inner tub 100, thereby preventing the stress concentration. Also, the visible range is not changed by the relative displacement between the first inner tub 110 and the second inner tub 120, so that it is more convenient to observe the position of the tray 400.

According to a preferred embodiment, referring to fig. 4, a side of the first free end 111A of the first elastic piece 111 and/or the second free end 121A of the second elastic piece 121 facing the inside of the tub is provided with a protrusion 130 for preventing the first free end 111A and/or the second free end 121A from hooking up the garbage in the process of converting the first elastic piece 111 from the bent state to the straightened state. Since if the first free end 111A and the second free end 121A are integrally formed in a thin plate shape when the garbage is much, it is likely that the large, soft and light garbage such as toilet paper and plastic packing bag on the top is caught and hung on the first free end 111A and the second free end 121A, and even dropped out of the inner tub 100, causing inconvenience to the user. Preferably, the edges of the first free end 111A and the second free end 121A are rounded to reduce the chance of the first elastic piece 111 and the second elastic piece 121 tearing the garbage bag during movement.

According to a preferred embodiment, the fifth link 250 for pushing the lid 520 of the trash can is linked with the foot lever 270, the fifth link 250 is pushed upward to open the lid 520 when the foot lever 270 is depressed, and the lid 520 is closed by its own weight and the return spring 300 when the foot lever 270 is released. Preferably, referring to fig. 5, one end of the fifth link 250 is hinged to the tub cover 520, and the other end of the fifth link 250 is hinged to the foot lever 270. Alternatively, the fifth link 250 is indirectly connected to the foot lever 270 through the sixth link 260. Referring to fig. 1 and 2 again, for example, one end of the fifth link 250 is hinged to the tub cover 520, the other end of the fifth link 250 is hinged to one end of the sixth link 260, and the other end of the sixth link 260 is hinged to the foot lever 270. Preferably, the fifth link 250 can be partially rotated in a plane in which the foot lever 270 and the fifth link 250 are located while the other end of the fifth link 250 is hinged to the foot lever 270 to accommodate the angle change of the fifth link 250 when the tub cover 520 is opened and closed. Preferably, while the fifth link 250 is indirectly connected to the foot lever 270 through the sixth link 260, the fifth link 250 can only slide up and down with respect to the trash can to convert the displacement of the sixth link 260 into the displacement of the fifth link 250 pushing the tub cover 520 as much as possible.

According to a preferred embodiment, referring again to fig. 2, the opening angle α of the lid 520 opened to the extreme position is acute and the lid 520 is provided with a weight 521. In this way, when the pedal lever is released, the tub cover 520 may not only be closed under its own weight, but also drive the second inner tub 120 and the tray 400 together with the return spring 300 by using the weight of the tub cover 520 and the weight block 521. Preferably, the rim of the tub cover 520 and/or the rim of the outer tub 510 of the trash can are provided with rubber buffer members. Preferably, in the case that rubber buffer elements are disposed at the edges of the can cover 520 and the outer tub 510 of the trash can, an annular groove is disposed at the middle of a first rubber buffer element on the can cover 520 along the edge of the can cover, and an annular flange adapted to the annular groove is disposed at a second rubber buffer element on the outer tub 510 along the edge of the outer tub. Therefore, the barrel cover and the outer barrel can be accurately positioned when the barrel cover and the outer barrel are covered, and garbage scraps or liquid cannot be accumulated on the edge of the outer barrel or the edge of the barrel cover.

According to a preferred embodiment, the waste compaction assembly can further comprise at least one damping element 600. One end of the damping member 600 may be hinged to the foot lever 270, and the other end of the damping member 600 may be hinged to the garbage can. Thus, the chance of damage to the components due to over-slamming of the lid 520 and/or over-rapid compression of the trash can is reduced. Preferably, a first damping coefficient of a first motion state of damping element 600, which is the motion state of damping element 600 during depression of the foot lever, is smaller than a second damping coefficient of a second motion state of damping element 600 after release of the foot lever, which is opposite to the motion direction of the first motion state. Different damping coefficients are set, so that great force is required when the pedal rod 270 is stepped on, and the probability that the barrel cover 520 is closed too hard and/or the garbage compression speed is too high to cause damage to parts can be prevented. Shock absorbers which are adjustable in the magnitude of both tensile and compressive damping are well known and therefore the structure of the shock absorber is not further limited herein.

According to an alternative embodiment, referring again to fig. 2, the damping element 600 and the return spring 300 are respectively disposed at both sides of the first fulcrum 281 of the foot lever 270, one end of the damping element 600 is hinged to the foot lever 270, and the other end of the damping element 600 is hinged to the bottom 530 of the trash can. One end of the return spring 300 is hinged to the pedal lever 270, and the other end of the return spring 300 is hinged to the bottom 530 of the trash can. At this time, the first motion state is a stretching process, and the second motion state is a compressing process. I.e. the tensile damping coefficient is smaller than the compressive damping coefficient.

According to another alternative embodiment, referring to fig. 5, the damping element 600 and the return spring 300 are both disposed on the same side of the first fulcrum 281 of the foot lever 270, preferably between the foot lever and the first fulcrum 281, one end of the damping element 600 is hinged to the foot lever 270, and the other end of the damping element 600 is hinged to the bottom 530 of the trash can. One end of the damping element 600 is hinged to the pedal lever 270, and the other end of the damping element 600 is hinged to the bottom 530 of the trash can. One end of the return spring 300 is hinged to the pedal lever 270, and the other end of the return spring 300 is hinged to the bottom 530 of the trash can. At this time, the first motion state is a compression process, and the second motion state is a tension process. I.e. the compression damping coefficient is smaller than the tension damping coefficient. It will be appreciated by those skilled in the art that the damping element 600 may also have alternative installation manners, for example, the damping element 600 is disposed on a foot bar, one end of the damping element 600 is hinged to the foot bar, and the other end of the damping element 600 is hinged to the wall of the outer tub 510. These alternative mounting means are intended to be within the scope of the present invention and are not to be taken as examples.

Preferably, the tray 400 is inserted into the second inner tub 120 to be slidable up and down, and has a lower end hinged to the second connecting rod 220.

Preferably, the first viewing window 150 is embedded in a tub wall of the outer tub 510.
