Description

Storage assembly for fluffy articles

The invention relates to a division application of a garbage compression assembly, which has the application number of 201810286063.6, the application date of 2018, 04 and 02, and the application type of the division application.

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 compression of refuse, but can be applied to other aspects, such as the aerospace field, as an object price clamping assembly for preventing objects from floating randomly. For another example, the utility of the garment storage assembly is applied to garment storage, particularly fluffy garments, such as down jackets, as a garment storage assembly, so that the volume occupied by the fluffy garments is reduced.

Background

The garbage bin is a common article in daily life, and is used as a container for storing garbage, and a bin-shaped structural form with a certain depth is adopted in many cases, and garbage is put into the bin through an opening at the top or at the side surface of the bin. When the garbage can is matched with the garbage bag for use, the interior of the garbage can be kept clean. However, most of the current garbage cans do not have a garbage compression function, garbage bags are cheap, garbage is generally dirty, and few people can actively compress the garbage. Therefore, when loose and porous garbage such as paper clusters, packaging boxes and disposable paper cups is contained, the utilization rate of the space is low, the storage amount of the garbage is greatly reduced, and the garbage bag is insufficiently utilized. Most of the garbage bags are plastic bags, are not easy to degrade, and are a main source of white pollution. Therefore, the garbage can does not compress garbage, so that not only is the waste of resources caused, but also the environmental pollution is aggravated.

Few existing garbage cans with garbage compression function 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: the garbage can comprises a can body, a can cover, a pressing plate and a hydraulic pump, wherein a garbage cavity is formed in the downward depression of the upper surface of the can body, the can cover is hinged to the upper surface of the can body, the can cover the opening of the can body, the hydraulic pump is fixed to the lower surface of the can cover in the state that the can cover is opened, the pressing plate is connected with a piston rod on the hydraulic pump, and the piston rod can enable the pressing plate to move in the vertical direction. The garbage bin overcomes the problems that when the garbage bin stores garbage in the prior art, when the gap between the garbage is too large, the using space inside the garbage bin is not fully utilized, and the garbage bin stores garbage in an amount far less than the actual garbage storage amount.

For another example, chinese patent document with grant publication number CN105035603B discloses a pedal-type compressible garbage can, in which a compressing and hammering transmission device for compressing garbage and a garbage can liner for holding garbage are provided in a housing, and a garbage inlet and a liner removing opening are provided in the housing; the 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 are connected with the compression device, and the lower ends of the two side inhaul cables are respectively connected with the two ends of the 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 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 manner and is positioned above the opening of the inner container of the dustbin. The garbage can is adopted to compress garbage, so that the space utilization rate of the garbage can is improved, the containing capacity of the garbage can is improved, and the compressed garbage is convenient to carry and transport.

The two kinds of garbage cans have two common problems, namely, when garbage is compressed, the parts for compressing the garbage can be in direct contact with the garbage, and in some cases, sticky garbage, such as toilet paper for blowing nose, garbage bags filled with oil cakes and the like, can be stuck on a compression assembly, so that the stuck garbage needs to be manually cleaned, and the time and the labor are wasted. Moreover, when the garbage is compressed, the surfaces of the garbage-compressing components may adhere to some liquid and semi-solid dirt such as nasal discharge, phlegm, juice on fruit peel, leftover particles and the like, and the dirt is not easy to be perceived by naked eyes, but a large amount of bacteria can grow on the garbage-compressing components in the long term, and the garbage-compressing components are not replaced as often as garbage bags, are usually used for life, are cleaned frequently, waste labor force is wasted, and health problems of indoor personnel can be caused due to the fact that cleaning is not performed frequently; 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 garbage bin compression assemblies that compress the garbage are located on the sides, compressing the garbage by moving the platen sideways.

For example, chinese patent document with grant publication number CN203047913U discloses a dustbin with lateral compression, which comprises a case body, at least one bar-shaped groove is arranged on the side wall of the case body, and a simple compression assembly for laterally compressing garbage is arranged at the corresponding position of the bar-shaped groove on the case body. The advantages are that: the up-down compression in the prior art is changed into horizontal unidirectional or bidirectional compression of garbage, and the structure is simple; the elastic pressing piece can automatically rebound to the original position, and the operation is convenient. The utilization rate of the dustbin is improved, the dustbin is favorable for environmental protection, and the dustbin is easy to maintain and popularize. However, this patent has a problem in that the outwardly extending push rod is easily brought into contact with the limbs of the person to cause the garbage can to be dumped and the garbage to be scattered from the garbage bag.

It follows that there is a strong need in the art for a trash compaction assembly that facilitates compaction of trash and reduces bacterial growth on the components that compress the trash.

Disclosure of Invention

Aiming at the defects of the prior art, the invention provides a garbage compression assembly, which can shrink the common opening when the first inner barrel and the second inner barrel which are sleeved with each other slide relatively, and can generate the acting force for compressing garbage when the common opening is folded.

According to a preferred embodiment, a garbage compression assembly comprises an inner barrel, a pedal rod and a return spring, wherein the return spring is used for enabling the pedal rod to rotate and return through elasticity when the pedal rod is not subjected to manually applied acting force, the inner barrel comprises a first inner barrel and a second inner barrel arranged in the first inner barrel, at least three first elastic pieces are arranged on the upper part of the first inner barrel, at least three second elastic pieces are arranged on the upper part of the second inner barrel, a first free end of each first elastic piece and a second free end of at least one second elastic piece are fixedly connected to form a shared opening which can be contracted when the pedal rod is relatively slid, and can generate acting force for compressing garbage when the shared opening is closed, when the pedal rod is mounted on an outer barrel of the garbage barrel, a part, which is positioned below the first elastic pieces, of the first inner barrel is fixedly connected with the inner wall of the garbage barrel, wherein the bottom of the inner barrel is provided with at least three second elastic pieces, a first free end of each first elastic piece and a second free end of each first elastic piece is fixedly connected with a second free end of at least one second elastic piece, so that when the pedal rod is relatively slid, the pedal rod is driven to move downwards, and the pedal rod is correspondingly pushed downwards, and a pedal rod is correspondingly pushed downwards; when the pedal rod is loosened, the first connecting rod pulls the second inner barrel to move downwards under the driving of the pedal rod, and the second connecting rod pushes the tray to move upwards under the driving of the pedal rod. The garbage can compress the input garbage, improves the utilization rate of the space in the garbage can, can continuously compress the garbage, and prevents the garbage from recovering the original volume due to elasticity after compressing the garbage for a short time.

According to a preferred embodiment, the second elastic sheet is provided with an anti-pinch element for preventing the disposal bag from being pinched between the first elastic sheet and the second elastic sheet. Thus, the probability of breakage of the garbage bag can be reduced.

According to a preferred embodiment, the garbage compression assembly further comprises a barrel cover of the garbage can and a fifth connecting rod which is used for pushing the barrel cover open and is linked with the pedal rod, wherein the opening angle of the barrel cover which is opened to the limit position is an acute angle, and the barrel cover and/or the barrel cover are/is internally provided with a balancing weight. Through this mode, when loosening the pedal pole, the bung not only can be closed under self gravity effect, can also utilize the gravity of bung and balancing weight and return spring together drive second inner barrel and tray, increase the effort of compression rubbish, improve the effect of compression rubbish.

According to a preferred embodiment, the garbage compression assembly further comprises at least one damping element, one end of which is hinged to the foot lever and the other end of which is hinged to the garbage can, wherein the first damping coefficient of the first state of motion of the damping element is smaller than the second damping coefficient of the second state of motion opposite to the direction of motion of the first state of motion, the first state of motion being the state of motion of the damping element during the foot lever being depressed, the second state of motion being the state of motion of the damping element after the foot lever is released. Therefore, the probability of damage to parts caused by too strong closing of the barrel cover and/or too high garbage compression speed can be reduced. In addition, by setting different damping coefficients, the pedal can be prevented from being stepped on by excessive damping when the pedal rod is stepped on, so that larger force is required for stepping on the pedal, and the possibility that the barrel cover is closed too hard and/or the garbage compression speed is too fast to cause damage to parts can be prevented.

According to a preferred embodiment, a waste compression assembly comprises a first inner barrel, and a second inner barrel which can slide relative to the first inner barrel, wherein the first inner barrel and the second inner barrel are nested and connected with each other only at the top in a manner that a common opening can be contracted when the top slides relative to each other, and thereby a force for compressing waste can be generated when the common opening is closed.

According to a preferred embodiment, during the collapsing of the common opening, the horizontal cross-sectional dimension of at least a portion of the area of the first and/or second inner tub adjacent to the common opening is gradually reduced and the area nearer to the common opening has a greater tendency to be reduced. By the method, the volume in the garbage bag can be further compressed, and garbage can not be extruded from the bag opening of the garbage bag in the compression process.

According to a preferred embodiment, the second inner barrel is nested in the first inner barrel, and the bottom of the second inner barrel is composed of a tray capable of sliding in the second inner barrel, wherein the tray moves towards the direction approaching the common opening when the common opening is folded; the tray moves away from the common opening when the common opening is opened. If the tray is motionless, the acting force for compressing the garbage can only be generated when the garbage is loaded in the adjacent area of the shared opening, and at the moment, due to excessive garbage, gaps exist among some garbage, but too thick garbage is filled outside the gaps and is difficult to compress, therefore, the movable tray is used, and moves towards the direction approaching the shared opening when the shared opening is folded, so that the movable tray can compress the garbage in advance, reduce the internal gaps and improve the effect of compressing the garbage; moreover, the tray of the present invention moves away from the common opening when the common opening is opened, so that the capacity of the present invention to contain garbage is increased.

According to a preferred embodiment, the common opening is formed by at least a first free end of at least two first elastic pieces arranged at intervals on the upper part of the first inner barrel and a second free end of at least two second elastic pieces arranged at intervals on the upper part of the second inner barrel, wherein each first free end and at least one second free end are fixedly connected.

According to a preferred embodiment, the garbage compression assembly further comprises a lid pivotally connected to the outer tub of the garbage can and having a maximum opening angle of an acute angle, and the lids are gradually closed in a manner of being interlocked with each other during the folding of the common opening, and/or the lids are gradually opened in a manner of being interlocked with each other during the opening of the common opening. In this way, when the pedal rod is loosened, the barrel cover can be closed under the action of gravity of the barrel cover and the common opening, and the shrinkage of the barrel cover and the common opening is linked with each other, so that the acting force of garbage compression can be indirectly increased by utilizing the gravity of the barrel cover, and the effect of garbage compression is improved.

According to a preferred embodiment, a garbage compression assembly comprises a first inner tub and a second inner tub slidable in a vertical direction along the first inner tub, wherein the first inner tub and the second inner tub are connected to each other in a nested manner to the common opening only at a top portion thereof in a retractable manner of the common opening, and thereby a force for compressing garbage can be generated when the common opening is closed, wherein a compression force applied by a link assembly capable of opening and closing a tub cover of the garbage tub is received at a bottom end of the second inner tub sliding opposite to the common opening, for compressing garbage put in through the common opening, and wherein the force for compressing garbage and the compression force applied by the link assembly are offset each other in a case where the tub cover is closed, so that continuous compression of garbage contained in the second inner tub can be achieved while the tub cover of the garbage tub is firmly closed. Through the mode, bacteria can be prevented from breeding on the part for compressing the garbage, odor emission is reduced, and the garbage can be continuously compressed.

The trash compaction assembly may further include a second inner tub 120 that is capable of sliding relative to the first inner tub 110. Preferably, the first and second inner tubs 110 and 120 are nested with each other to be connected to the common opening only in such a manner that the top portion is contractible by the common opening when relatively slid, and thus can generate a force for compressing the garbage when the common opening is closed. Preferably, the second inner tub 120 is nested in the first inner tub 110 and is fixedly connected only at the common opening. Preferably, at least a partial region of the first and/or second inner tub 110, 120 adjacent to the common opening may be drawn toward the inside of the tub when an inward tensile force is applied.

According to a preferred embodiment, the horizontal cross-sectional dimension of at least a portion of the area of the first and/or second inner tub 110, 120 adjacent to the common opening gradually decreases during the collapsing of the common opening. Preferably, the region of the at least partial region that is more adjacent to the common opening has a greater tendency to shrink.

According to a preferred embodiment, the second inner tub 120 may be nested in the first inner tub 110. The bottom of the second inner tub 120 may be formed of a tray slidable within the second inner tub 120. The tray may move in a direction approaching the common opening when the common opening is collapsed. The tray is movable away from the common opening when the common opening is opened. Preferably, the tray moves in a direction approaching the common opening in a manner to be interlocked with each other when the common opening is collapsed. Preferably, the tray is movable in a direction away from the common opening in a manner to be interlocked with each other when the common opening is opened.

According to an alternative embodiment, the common opening may be composed of first free ends of at least two first elastic pieces spaced apart from the upper portion of the first inner tub 110 and second free ends of at least two second elastic pieces spaced apart from the upper portion of the second inner tub 120. Each first free end is fixedly connected with at least one second free end. Preferably, the first elastic piece is integrally provided on the first inner tub. Preferably, the first elastic piece is detachably connected to the first inner barrel.

According to an alternative embodiment, the lower part of the first inner tub may be a plastic tub, while the upper part is stuck with a tub-shaped rubber sleeve. At least two long plastic blocks are stuck in the rubber sleeve at intervals, and at least two second elastic sheets are arranged at intervals on the upper part of the second inner barrel 120. Each plastic block is connected with at least one second elastic sheet. Therefore, when the second inner barrel moves downwards, the rubber sleeve with the plastic blocks can shrink inwards to compress garbage.

According to a preferred embodiment, the garbage compression assembly may further comprise a lid pivotally connected to the outer tub of the garbage can and having a maximum opening angle α of an acute angle. Preferably, the tub covers may be gradually closed in a manner of being interlocked with each other during the process of folding 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 trash compaction assembly has a linkage assembly that includes a foot bar. Preferably, the second inner tub may be driven to move in the first direction by the link assembly to open the common opening when the foot lever is depressed. Preferably, the tray is driven by the linkage assembly to move away from the common opening when the foot bar is depressed. Preferably, the lid is driven to open by the linkage assembly when the foot lever is depressed.

According to a preferred embodiment, the waste compression assembly further comprises at least one resilient element 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, when the pedal lever is released, the elastic potential energy of the elastic member is released and thereby the second inner tub is driven to move toward the second direction opposite to the first direction by the link assembly to collect the common opening. Preferably, upon release of the foot bar, the elastic potential energy of the elastic element is released and thereby drives the tray through the linkage assembly in a direction approaching the common opening. Preferably, upon release of the foot lever, the elastic potential energy of the elastic element is released and thereby drives and/or assists the lid closure via the linkage assembly. Preferably, the link assembly may further include at least one of a first link, a second link, a third link, a fourth link, a fifth link, and a sixth link. Preferably, it will be readily apparent to those skilled in the art that a portion of the link assembly may be modified to be a pulley assembly to achieve the same technical result.

Preferably, when the common opening is opened, the external force applied to the elastic element is converted into elastic potential energy of the elastic element, and the external force provides power for the relative sliding of the first inner barrel and the second inner barrel to open the common opening, and when the external force is released, the common opening is folded and the elastic potential energy of the elastic element provides power for the relative sliding of the first inner barrel and the second inner barrel to close the common opening.

Example 2

This embodiment may be a further improvement and/or addition to embodiment 1, and the repeated description is omitted. In addition to this embodiment, the preferred implementation of the other embodiment may be provided in whole and/or in part without conflict or contradiction.

According to a preferred embodiment, a garbage compression assembly may include a first inner tub 110 and a second inner tub 120 slidable in a vertical direction along the first inner tub 110. Preferably, the first and second inner tubs 110 and 120 are nested with each other only at the top in such a manner as to be contractible to a common opening, and thus are capable of generating an elastic force for compressing garbage when the common opening is closed. Preferably, a compression force applied by a link assembly, which can also be used to open and close the lid of the trash can, is received at the bottom end of the second inner tub 120 opposite to the common opening, to compress the trash input through the common opening. Preferably, the elastic force for compressing the garbage and the compression force applied by the link assembly are offset from each other in the case that the cover is closed, so that continuous compression of the garbage contained in the second inner tub 120 can be achieved while the cover of the garbage can is firmly closed.

Example 3

This embodiment may be a further improvement and/or addition to embodiments 1, 2 or a combination thereof, and the repeated description is omitted. In addition to this embodiment, the preferred implementation of the other embodiment may be provided in whole and/or in part without conflict or contradiction.

According to a preferred embodiment, referring to fig. 1, 2 and 3, the trash compression assembly may include an inner tub 100, a foot lever 270 and a return spring 300. The return spring 300 may be used to rotationally return the foot bar 270 by an elastic force when the foot bar 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 provided inside the first inner tub 110. The upper portion of the first inner tub 110 may be provided with at least two first elastic pieces 111. The second inner tub 120 may be provided at an upper portion 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 being mounted on the outer barrel 510 of the garbage can, the part of the first inner barrel 110 positioned below the first elastic piece 111 is fixedly connected with the inner wall of the garbage can. The bottom of the inner tub 100 is formed of a tray 400 provided in the second inner tub 120. The tray 400 can slide up and down with respect to the second inner tub 120.

Preferably, the trash compaction assembly may further include a first link 210 and a second link 220 that are coupled to the foot bar 270. Preferably, when the foot lever 270 is depressed, the first link 210 pushes the second inner tub 120 to move upward under the driving of the foot lever 270 and the second link 220 pulls the tray 400 to move downward under the driving of the foot lever 270. Preferably, when the foot lever 270 is released, the first link 210 pulls the second inner tub 120 to move downward under the driving of the foot lever 270 and the second link 220 pushes the tray 400 to move upward under the driving of the foot lever 270. This rubbish compression subassembly compresses rubbish in the disposal bag through crooked first elastic sheet, second elastic sheet and flexible tray realization, and the first elastic sheet of compression rubbish in-process is inwards crooked, drives the sack of the disposal bag of cover on first elastic sheet and draws in, and the tray upward movement for accommodation space of rubbish reduces, and rubbish compression subassembly can not with rubbish direct contact in the compression process, can solve the problem of easy dirty and easy breeding bacterium on the rubbish compression subassembly, and moreover, rubbish compression process has utilized return spring, can need not manual or electric operation after loosening the pedal pole, and convenient energy saving 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 gradually increases from the first fixed end 111B to the first free end 111A of the first elastic sheet 111. In this way, 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 bags are damaged or the compression effect is reduced due to the fact that the first free ends touch each other in the compression process can be reduced.

According to a preferred embodiment, the second elastic sheet 121 may be provided with a grip preventing member 140 for preventing the garbage bag from being gripped between the first elastic sheet 111 and the second elastic sheet 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 into the tub of the inner tub 100. Because if the first free end and the second free end are integrally formed in a sheet shape when there is a lot of garbage, it is likely that large, soft and light garbage such as toilet paper and plastic packing bags on the top will be caught, hung on the first free end and the second free end, and even dropped into the inner tub, causing inconvenience to the user. Thus, in this way, the inconvenience of hanging the garbage at the top on the first free end and/or the second free end or throwing out the garbage bag to the user can be reduced.

According to a preferred embodiment, referring to fig. 6, a first brush 410 protruding obliquely upward may be provided around the upper surface of the tray 400 contacting the garbage bag. The contour of the bristles of the first brush 410 encloses the contour of the tray 400 in a first projection plane toward the ground when the trash can is placed on the ground. Thus, the bristles of the first brush 410 can prevent the garbage bag from being caught in the slit to be damaged or to hinder the relative movement between the first and second inner drums after the tray is mounted in the second inner drum.

According to a preferred embodiment, referring to fig. 7, the third free ends of the bristles of the first brush 410 may be in a bent state. Because of the different quality and thickness of the bags, the straightened softer bristles may also in extreme conditions puncture some thinner bags, resulting in the outflow of liquid from the bags. Thus, the third free ends of the bristles are arc-shaped, so that the possibility of damage to the garbage bag can be further reduced. For ease of viewing, only one preferred embodiment of one bristle of the first brush 410 is schematically shown 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 downwardly recessed to form an arc-shaped recess 420, and the first brush 410 is adhered to the edge of the recess 420. Through this mode to make rubbish in the disposal bag can gather to the middle part as far as possible, reduce the rubbish and be pressed from both sides the possibility of gap, 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, simplify the structure and the setting degree of difficulty of first brush.

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, the obstruction of the second elastic sheet to the first elastic sheet can be reduced in the garbage compression process, and the elastic force of the return spring is converted into the acting force for compressing garbage more, so that the compression effect is better.

According to a preferred embodiment, referring again to fig. 2, the garbage compression assembly may further comprise a lid 520 of the garbage can, a fifth link 250 for pushing open the lid 520 and being linked with a foot lever 270. Preferably, the opening angle α of the tub cover 520 to the limit position is an acute angle and the tub cover 520 and/or the tub cover 520 are provided with the balancing weight 521. The multiple connecting rods are adopted to connect all the components, the actions of uncovering and opening the garbage bag mouth are completed by one action of stepping on the pedal, and garbage compression and box cover actions are automatically completed when the pedal is released, so that the garbage bag cover garbage bag is convenient to use. When the pedal is not stepped on, the barrel cover is closed under the action of gravity and the action of the return spring 300 pushing the pedal lever 270 to drive the fifth connecting rod 250; meanwhile, under the driving of the foot lever 270, the first connecting rod 210 drives the second inner barrel 120 to move downwards, and as the first inner barrel and the second inner barrel are fixedly connected at the top, the relative movement between the two causes the first elastic sheets to generate bending deformation, the first elastic sheets distributed circumferentially 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 trash compaction assembly may further comprise at least one damping element 600. One end of the damping element 600 may be hinged to the foot bar 270. The other end of the damping element 600 may be hinged to the trash can. Preferably, the first damping coefficient of the first state of motion of the damping element 600 is smaller than the second damping coefficient of the second state of motion opposite to the direction of motion of the first state of motion, wherein the first state of motion is the state of motion of the damping element 600 during stepping down of the foot lever and the second state of motion is the state of motion of the damping element 600 after releasing the foot lever.

Example 4

This embodiment may be a further improvement and/or addition to embodiments 1, 2, 3 or a combination thereof, and the repeated description is omitted. In addition to this embodiment, the preferred implementation of the other embodiment may be provided in whole and/or in part without conflict or contradiction.

According to a preferred embodiment, referring to fig. 1 and 2, a trash compression assembly may include an inner tub 100, a foot bar 270, and a return spring 300. The return spring 300 can assist in returning the foot bar 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. The upper portion of the first inner tub 110 may be provided with at least three first elastic pieces 111. 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 tub 120 is nested within the first inner tub 110, there may be a clearance fit between the first inner tub 110 and the second inner tub 120 except for the fixedly connected portions of the first elastic piece 111 and the second elastic piece 121 at the first free end 111A and the second free end 121A. That is, the remaining portions of the first and second inner tubs 110 and 120 may be relatively moved, except for the fixedly connected portion. The first and second inner barrels 110 and 120 may be relatively moved in the axial direction. Preferably, the foot rest 270 is provided with a pedal at its free end, and a cleat may also be provided on the pedal for the foot to apply force to the foot rest 270.

Preferably, the portion of the first inner tub 110 located under the first elastic piece 111 is fixedly coupled with the inner wall of the trash can when mounted to the trash can. Preferably, the outer wall of the first inner tub 110 is provided with a mounting part 112, and the mounting part 112 may be detachably mounted to the inner wall of the trash can. For example, the mounting portion 112 is a convex flange and is fastened to the inner wall of the trash can by a flange fastener and/or a bolt. For another example, a boss adapted to the outer diameter of the first inner barrel 110 is provided on the inner wall of the dustbin, the first inner barrel 110 is directly clamped at the boss, and then the first inner barrel 110 and the second inner barrel are fixedly connected by a bolt penetrating through the outer shell of the dustbin and a part of the bolt 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 the inner tub 100 of the general trash can, i.e., the fixed bottom moves downward as the second inner tub 120 moves downward, resulting in limited ability to compress trash. Preferably, the middle of the tray 400 is provided with a downwardly concave circular arc-shaped pit so that garbage in the garbage bag can be gathered toward the middle as much as possible.

Preferably, the tray 400 is provided at an edge thereof with a first brush protruding upward obliquely upward and a bristle protruding direction of the first brush is directed outward 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 tubs 110 and 120 when the tray 400 and the second inner tub 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 form, and the free ends thereof are bent. Although the stiffness of the first brush may be predetermined when designed, due to the varying quality and thickness of the bags, the straightened softer bristles may also in extreme conditions puncture some thinner bags, resulting in outflow of liquid from the bags. Therefore, the free end is arc-shaped, and the possibility of damage of the garbage bag can be further reduced. 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, some dust and sticky dirt.

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 trash compaction assembly may further include a first link 210 and a second link 220 that are coupled to the foot bar 270. Preferably, when the foot bar 270 is stepped down, the first link 210 may push the second inner tub 120 to move upward under the driving of the foot bar 270, and the second link 220 may pull the tray 400 to move downward under the driving of the foot bar 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 outwards, an entrance for garbage is formed, and the tray 400 also moves downward, so that the space for accommodating garbage constructed by the tray 400 and the second inner tub 120 is increased, and more garbage can be put in. Preferably, when the foot lever 270 is released, the first link 210 may pull the second inner tub 120 to move downward under the driving of the return spring 300 and the foot lever 270, and the second link 220 may push the tray 400 to move upward under the driving of the return spring 300 and the foot lever 270. Therefore, when the foot is released from the foot rest lever 270, the second inner barrel 120 moves downwards under the indirect action of the return spring 300, so that the inner second elastic piece 121 pulls the first elastic piece 111 to bend and fold towards the middle, and at the same time, the tray 400 also moves upwards under the indirect action of the return spring 300, so that the garbage in the garbage bag is clamped, the compression effect is improved, and the garbage containing space is reduced from two directions, so that the garbage bag has a certain compression effect when garbage is less.

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

According to another alternative embodiment, first link 210 and second link 220 may be indirectly coupled to foot bar 270 to effect a linkage. For example, the first trash compression assembly may also include a third link 230 and a fourth link 240. One end of the first link 210 may be hinged with the second inner tub 120, and one end of the second link 220 may be hinged with the tray 400. A position between both end points of the third link 230 is hinged with the second fulcrum 282. One end of the third link 230 near the first pivot 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 examples, and those skilled in the art will recognize that the first link 210 and the second link 220 may have other implementations that are linked with the foot rest lever 270, so that when the foot rest lever 270 is stepped down, the first link 210 may push the second inner tub 120 to move upward under the driving of the foot rest lever 270, and the second link 220 may pull the tray 400 to move downward under the driving of the foot rest lever 270. Or vice versa. These should fall within the scope of the present invention.

According to a preferred embodiment, the second link 220 may be a spring rod. Preferably, the spring rod has elastic force at least in its length direction and is stretchable in its length direction. Along with the increasing volume of the garbage, the lifting space of the tray 400 is limited, at this time, the second link 220 is compressed under the action of the tray 400, so that more garbage can be contained in the second inner tub 120, and the elastic connection of the second link 220 can ensure that the second link 220 does not react to other links, so that the tub cover 520 cannot be closed.

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 sheet 121 is to pull the first elastic sheet 111 downward to compress the garbage, the smaller width of the second elastic sheet 121 than the first elastic sheet 111 helps to reduce the influence of the reaction force of the second elastic sheet 121 on the bending of the first elastic sheet 111.

According to an alternative embodiment, the anti-pinch member 140 may be a second brush provided at both sides of the second elastic sheet 121. In this way, the garbage bag can be prevented from being sandwiched between the first elastic sheet 111 and the second elastic sheet 121. Preferably, the first bristle hardness of the bristles of the first brush is equal to or greater than the 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 provided between the garbage bag and the first elastic sheet 111, the anti-pinch layer being attached in a tubular shape over each of the second elastic sheets 121 in a state in which the first elastic sheet 111 is not bent. Preferably, the upper end of the anti-sandwich layer extends at least to the fixing point of the first elastic sheet 111 and the second elastic sheet 121, and the lower end of the anti-sandwich layer extends below the lower end of the second elastic sheet 121. Preferably, the anti-interlayer may be a rubber layer having elasticity or an elastic cloth. Preferably, the anti-sandwich 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 increases gradually 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 provided on the inner tub 100 and the light paths of the at least two first viewing windows 150 are at least partially overlapped. Thereby, the position of the tray can be observed more clearly. When the compressed garbage in the bin reaches the maximum volume, the tray 400 can be observed to descend to the lowest position through the first visual window 150, and the bin cover 520 is opened by pressing the pedal at this time, so that the garbage bag filled with the compressed garbage can be taken out.

According to a preferred embodiment, the first viewing window 150 is a through hole formed in the inner tub 100, for example, an oval through hole or an elongated through hole. The through holes may include a first through hole on the first inner tub 110 and a second through hole on the second inner tub 120. When the first elastic sheet 111 is in a non-bent state, the first outer contour of the first through hole coincides with the second outer contour of the second through hole or is at least partially enclosed within the second outer contour when the first through hole is seen in front view. Preferably, in case the first viewing window 150 is a through hole, the second through hole may be fitted with an anti-pinch transparent sheet adapted thereto to prevent the trash bag from being pinched between the first and second inner tubs 110 and 120 when the first and second inner tubs 110 and 120 are relatively displaced. Preferably, the inner tub 100 may be made of a transparent material, and the first viewing window 150 is a partial area of the inner tub 100. Accordingly, the degradation of the mechanical properties of the inner tub 100 due to the opening of the inner tub 100 can be reduced, and the occurrence of stress concentration can be prevented. Also, the visible range is not changed by the relative displacement between the first and second inner tub 110 and 120, so that it is more convenient to observe the position of the tray 400.

According to a preferred embodiment, see fig. 4, the first free end 111A of the first elastic sheet 111 and/or the second free end 121A of the second elastic sheet 121 are provided on the side facing into the tub with protrusions 130 for preventing the first free end 111A and/or the second free end 121A from catching garbage during the transition of the first elastic sheet 111 from the bent state to the straightened state. Because if the first and second free ends 111A and 121A are integrally formed in a sheet shape when there is a lot of garbage, it is likely that large, soft and light garbage such as toilet paper and plastic packing bags on the top will be caught, hung on the first and second free ends 111A and 121A, and even dropped out of the inner tub 100, causing inconvenience to the user. Preferably, the edges of the first and second free ends 111A, 121A are rounded to reduce the chance of the first and second elastic panels 111, 121 puncturing the trash 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, and when the foot lever 270 is depressed, the fifth link 250 is pushed upward to open the lid 520, and when the pedal is released, the lid 520 is closed by the self-weight and the return spring 300. 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, fifth link 250 is indirectly coupled to foot rest lever 270 via sixth link 260. Referring again to fig. 1 and 2, 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 rest lever 270. Preferably, when the other end of the fifth link 250 is hinged to the foot lever 270, the fifth link 250 can be partially rotated in the plane of the foot lever 270 and the fifth link 250 to accommodate the angular variation of the fifth link 250 when the tub cover 520 is opened and closed. Preferably, when 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 tub cover 520 to the extreme position is an acute angle and the tub cover 520 is provided with a weight 521. In this way, when the foot lever is released, the tub cover 520 may not only be closed by its own weight, but also drive the second inner tub 120 and the tray 400 together by the weight of the tub cover 520 and the weight 521 and the return spring 300. Preferably, the rim of the tub cover 520 and/or the rim of the outer tub 510 of the trash can is provided with a rubber buffer member. Preferably, in the case that the edges of the tub cover 520 and the outer tub 510 of the trash can are both provided with rubber buffer elements, the middle of the first rubber buffer element on the tub cover 520 is provided with an annular groove along the tub cover edge, and the second rubber buffer element on the outer tub 510 is provided with an annular flange along the outer tub edge, which is adapted to the annular groove. Therefore, the barrel cover and the outer barrel can be accurately positioned during covering, and garbage fragments or liquid cannot be accumulated at the edge of the outer barrel or the edge of the barrel cover.

According to a preferred embodiment, the trash compaction assembly may further comprise at least one damping element 600. One end of the damping element 600 may be hinged to the foot bar 270 and the other end of the damping element 600 may be hinged to the trash can. Thereby, the possibility of damage to parts caused by too hard closing of the tub cover 520 and/or too high compression of the garbage can be reduced. Preferably, the first damping coefficient of the first state of motion of the damping element 600 is smaller than the second damping coefficient of the second state of motion opposite to the direction of motion of the first state of motion, wherein the first state of motion is the state of motion of the damping element 600 during stepping down of the foot lever and the second state of motion is the state of motion of the damping element 600 after releasing the foot lever. By setting different damping coefficients, the pedal lever 270 can be prevented from being stepped on with large force, and the possibility of damage to parts caused by too high closing of the barrel cover 520 and/or too high garbage compression speed can be prevented. Shock absorbers which can adjust the magnitude of the tension damping and the compression damping are well known, and thus the structure of the shock absorber is not further limited here.

According to an alternative embodiment, referring again to fig. 2, the damping element 600 and the return spring 300 are respectively provided at both sides of the first pivot 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 compression process. I.e. the tensile damping coefficient is smaller than the compressive damping coefficient.

According to another alternative embodiment, see fig. 5, the damping element 600 and the return spring 300 are both arranged on the same side of the first fulcrum 281 of the foot lever 270, preferably between the foot and the first fulcrum 281, one end of the damping element 600 being hinged to the foot lever 270 and the other end of the damping element 600 being hinged to the bottom 530 of the dustbin. 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 compression process, and the second motion state is a stretching process. I.e. the compression damping coefficient is smaller than the tension damping coefficient. It will also be appreciated by those skilled in the art that the damping element 600 may have alternative mounting arrangements, such as having the damping element 600 disposed on a foot bar, with one end of the damping element 600 hinged to the foot bar and the other end of the damping element 600 hinged to the tub wall of the outer tub 510. These alternative mounting arrangements are intended to be within the scope of the present invention and are not intended to be limiting.
