Description

A kind of container

Technical Field

The invention relates to a compression device, in particular to a container.

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.

Accordingly, there is a strong need in the art for a trash can that facilitates compressing trash and reduces bacterial growth on the components that compress the trash.

Disclosure of Invention

The container comprises a first inner barrel and a second inner barrel which are sleeved with each other, wherein a shared opening is contracted when the first inner barrel and the second inner barrel slide relative to each other, acting force for compressing objects in the container can be generated when the shared opening is folded, the objects in the container are garbage, the opening of the garbage bag is synchronously contracted along with the shared opening due to the fact that the garbage bag is sleeved in the second inner barrel, in the process of compressing the objects, parts for compressing the objects are separated from the garbage through the garbage bag, bacteria cannot be bred, in addition, the folding of the opening of the garbage bag can also reduce the outward emission of peculiar smell generated by the garbage to a certain extent, the possibility of air pollution by the peculiar smell is reduced, and user experience is improved. However, the container of the present invention is not limited to use as a trash can, and the present invention can be applied to other aspects, for example, the aerospace field, as a container for holding articles to prevent the articles from floating at will. For another example, the present invention is applied to clothes storage, as a container for storing clothes, especially fluffy clothes such as down jackets, to reduce the volume occupied by the fluffy clothes.

According to a preferred embodiment, the container comprises an outer barrel and a first inner barrel, the first inner barrel is arranged in the outer barrel in a mode that the first inner barrel does not slide relative to the outer barrel, the container further comprises a second inner barrel nested in the first inner barrel, at least three first elastic sheets are arranged on the upper portion of the first inner barrel, at least three second elastic sheets are arranged on the upper portion of the second inner barrel, a first free end of each first elastic sheet and a second free end of at least one second elastic sheet are fixedly connected to form a common opening which is contracted through relative sliding of the first inner barrel and the second inner barrel on the top, and therefore acting force for compressing a contained object can be generated when the common opening is folded.

According to a preferred embodiment, the lower ends of the first inner barrel and the second inner barrel are opened, the second inner barrel is provided with a chassis which can move up and down relative to the second inner barrel, the container further comprises a pressure lever, and a return spring, a first connecting rod and a second connecting rod which are linked with the pressure lever, when the pressure lever is pressed down, the return spring is stretched or compressed by the pressure lever and is converted into elastic potential energy, and the first connecting rod pushes the second inner barrel to move upwards under the driving of the pressure lever, so that the common opening is opened, and the chassis is driven by the second connecting rod to move downwards; when the pressure lever is loosened, the elastic potential energy of the return spring is released to push the pressure lever to restore the original position, and meanwhile, the first connecting rod is driven by the pressure lever to pull the second inner barrel to move downwards, so that the common opening is folded, and the second connecting rod is driven by the pressure lever to push the chassis to move upwards. If the chassis is stationary, the force compressing the objects can only be generated when the objects are mounted in the vicinity of the common opening, and in this case, due to the large number of objects, some objects have gaps between them but are difficult to compress. For example, when the garbage can is used as a garbage can, the outside of the gap is often filled with too thick garbage and is difficult to compress, so that the garbage can uses a movable chassis which moves towards the direction approaching the common opening when the common opening is closed, so that the garbage can compress the contained object in advance, the inner gap is reduced, and the effect of compressing the contained object is improved; furthermore, the chassis 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 accommodate objects is increased. Moreover, the invention can realize the continuous compression of the input object and prevent the loaded object from restoring the original volume due to elasticity after the loaded object is compressed for a short time.

According to a preferred embodiment, the container further comprises a lid pivotally connected to the outer tub and a fifth link lever for pushing the lid open and linked with the pressure lever, wherein an opening angle of the lid open to the limit position is an acute angle. Through this mode, when loosening the depression bar, the bung not only can close under the action of gravity of self, can also utilize the gravity of bung and return spring to drive bucket and chassis in the second together, and the effort of the object is adorned in the increase compression, improves the compression effect of the object of compression dress.

According to a preferred embodiment, the container further comprises at least one damping element, one end of the damping element is hinged to the pressing rod, and the other end of the damping element is hinged to the outer barrel, wherein a first damping coefficient of a first motion state of the damping element is smaller than a second damping coefficient of a second motion state opposite to the motion direction of the first motion state, wherein the first motion state is a motion state of the damping element in the process of pressing down the pressing rod, and the second motion state is a motion state of the damping element after releasing the pressing rod. Therefore, the probability that the components are damaged due to the fact that the barrel cover is closed violently and/or the compression speed is too fast can be reduced. Moreover, different damping coefficients are set, so that great force is required for pressing the pedal by preventing overlarge damping generated when the pressure lever is pressed down, and the probability that the barrel cover is closed too violently and/or parts are damaged due to the overhigh compression speed can be prevented.

According to a preferred embodiment, the container comprises an outer barrel and a first inner barrel, the first inner barrel is arranged in the outer barrel in a mode that the first inner barrel does not slide relative to the outer barrel, the container further comprises a second inner barrel capable of sliding relative to the first inner barrel, the first inner barrel and the second inner barrel are connected with each other in a nested mode only at the top part and can contract a common opening when sliding relative to each other, and therefore acting force for compressing contained objects can be generated when the common opening is closed.

According to a preferred embodiment, during the collapsing of the common opening, at least a portion of the region of the first inner barrel and/or the second inner barrel adjacent to the common opening has a gradually decreasing horizontal cross-sectional dimension and a region adjacent to the common opening has a greater tendency to decrease. By the mode, the volume in the garbage bag can be further compressed, and the garbage cannot be extruded out of 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, the bottom of the second inner barrel is composed of a chassis capable of sliding in the second inner barrel, and when the common opening is closed, the chassis moves towards the direction approaching the common opening; the chassis moves away from the common opening when the common opening is opened.

According to a preferred embodiment, a first brush extending obliquely upwards is arranged around the upper surface of the base plate, and the bristles of the first brush extend outwards from the base plate, wherein the third free ends of the bristles of the first brush are arranged in a bent state so that the tips of the bristles do not contact with the contained object during the movement of the base plate. Therefore, after the chassis is arranged in the second inner barrel, the bristles of the first hairbrush can prevent a garbage bag or an object from being clamped into the gap to damage the garbage bag and/or the object or obstruct the relative movement between the first inner barrel and the second inner barrel. Moreover, the bent bristles can prevent the bristles from puncturing the contained objects in extreme conditions, for example, when the garbage can is used as a garbage can, because the garbage bags are different in quality and thickness, the straightened softer bristles can puncture some thinner garbage bags in extreme conditions to cause liquid of the garbage bags to flow out. Thus, the third free ends of the brush staples are bent, so that the possibility of breakage of the garbage bag can be further reduced. Furthermore, when the present invention is used as a container for receiving clothes, the outer surface of some down jackets is also thin, and if the first bristles are straightened, the first bristles may be punctured. Or, the bristles of the first brush may extend into the interlayer of the down jacket from the sewing position of the down jacket, so that the down feather may be taken out from the interlayer, and the sewing hole may be enlarged, so that the down feather is easy to leak out later. Therefore, the first bristles with bent ends can achieve the beneficial effect of protecting objects contained in the second inner barrel.

According to a preferred embodiment, the container further comprises a lid pivotally connected to the outer tub and having a maximum opening angle of an acute angle, and the lids are gradually closed in a manner of being linked to each other during the process of closing the common opening and/or gradually opened in a manner of being linked to each other during the process of opening the common opening. Through this mode, when loosening the depression bar, the bung not only can close under the action of gravity of self, moreover, because the bung links each other with the shrink of sharing open-ended, can also utilize the indirect effort that increases the compression dress object of the gravity of bung, improves the effect of compression dress object.

According to a preferred embodiment, a container comprises an outer barrel and a first inner barrel, the first inner barrel is arranged in the outer barrel in a manner that the first inner barrel does not slide relative to the outer barrel, the container further comprises a second inner barrel capable of sliding in a vertical direction along the first inner barrel, wherein the first inner barrel and the second inner barrel are nested and connected with each other at the shared opening only at the top in a manner that a shared opening can be contracted, and therefore acting force for compressing contained objects can be generated when the shared opening is closed, wherein the sliding bottom end of the second inner barrel opposite to the shared opening bears the compression force applied by a connecting rod assembly capable of opening and closing a barrel cover of the container so as to compress the objects thrown through the shared opening, and wherein the acting force for compressing the contained objects and the compression force applied by the connecting rod assembly of the barrel cover are the compression force applied when the contained objects are compressed And the two parts are mutually offset, so that the objects contained in the second inner barrel can be continuously compressed while the barrel cover is stably closed.

Preferably, upon release of the plunger, the resilient potential energy of the resilient element is released and thereby drives and/or assists closure of the lid by 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 is easily imaginable for a person skilled in the art to modify part of the connecting-rod assembly to a pulley assembly, achieving the same technical effect.

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, a container 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 inner barrel 110 and the second inner barrel 120 are nested with each other in the common opening only at the top in such a manner as to be contractible by the common opening, and thus can generate an elastic force for compressing the contained objects when the common opening is closed. Preferably, a bottom end of the second inner barrel 120 opposite to the common opening receives a compressive force applied by a link assembly that can also be used to open and close a lid of the container, so as to compress objects thrown through the common opening. Preferably, the elastic force for compressing the contents and the compression force applied by the link assembly are offset from each other when the lid is closed, so that the contents of the second inner barrel 120 can be continuously compressed while the lid of the container is stably closed.

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, 2 and 3, the container may include an inner tub 100, a pressing lever 270 and a return spring 300. The return spring 300 may be used to rotationally return the pressure lever 270 by an elastic force when the pressure 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, a portion of the first inner tub 110 located below the first elastic sheet 111 is fixedly connected to an inner wall of the outer tub 510. The bottom of the inner tub 100 is formed of a bottom plate 400 provided in the second inner tub 120. The bottom chassis 400 may slide up and down with respect to the second inner tub 120.

Preferably, the container may further include a first link 210 and a second link 220 linked with the pressing lever 270. Preferably, when the pressing rod 270 is pressed, the first connecting rod 210 pushes the second inner tub 120 to move upward under the driving of the pressing rod 270 and the second connecting rod 220 pushes the bottom plate 400 to move downward under the driving of the pressing rod 270. Preferably, at the time of releasing the pressing rod 270, the first connecting rod 210 pulls the second inner tub 120 to move downward by being driven by the pressing rod 270 and the second connecting rod 220 pushes the bottom plate 400 to move upward by being driven by the pressing rod 270. This container is through crooked first flexure strip, the rubbish in the rubbish bag is compressed to second flexure strip and flexible chassis realization, the first flexure strip of object in-process of compression dress is incurved, the sack of the disposal bag on the first flexure strip of drive cover draws in, and chassis upward movement, make the accommodation space of rubbish reduce, container can not with rubbish direct contact in the compression process, can solve the problem of easily dirty and easily breeding the bacterium on the container, moreover, rubbish compression process has utilized return spring, can need not manual or electric operation after loosening the depression bar, convenient energy saving again promptly. Preferably, in the collapsed state of the common opening, the first elastic sheet and/or the second elastic sheet has a tendency to return to a straightened state to expand the common opening.

According to a preferred embodiment, referring again to fig. 2, 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. 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 objects or the garbage bags are damaged or the compression effect is reduced due to mutual contact of the first free ends in the compression process can be reduced.

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. Without the projection, the first free end 111A and/or the second free end 121A have a tendency to hook out the contained object. For example, when the container of the present invention is used as a trash can, since when there is much trash, 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 trash such as toilet paper and plastic packing bags on the top is caught and hung on the first free end and the second free end, and even dropped into the inner tub, causing inconvenience to a 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 bottom chassis 400 contacting the garbage bag. When the container is seated on the ground, the bristles of the first brush 410 are contoured to enclose the contour of the bottom plate 400 in a first plane of projection toward the ground. Therefore, after the chassis is installed in the second inner barrel, the bristles of the first brush 410 can prevent objects or garbage bags from being clamped into the gap to cause damage or hinder relative movement between the first inner barrel and the second inner barrel.

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 bottom chassis 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 contained object, 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 more converted into the acting force for compressing the contained object, and the compression effect is better.

According to a preferred embodiment, referring again to fig. 1, the container may further include a tub cover 520, and a fifth link 250 for pushing the tub cover 520 open and cooperating with the pressing 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 pressing down a footboard action to accomplish rubbish compression and lid action voluntarily when loosening the footboard, convenient to use. When the pedal is not pressed down, the barrel cover is closed under the action of gravity and a return spring 300 to push the pressure rod 270 to drive the fifth connecting rod 250; meanwhile, under the driving of the pressure 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 chassis 400 to ascend, thereby realizing the process of compressing the loaded objects.

According to a preferred embodiment, the container may further comprise at least one damping element 600. One end of the damping element 600 may be hinged to the pressure lever 270. The other end of the damping member 600 may be hinged on the outer tub. Preferably, a first damping force of a first movement state of the damping element 600, which is a movement state of the damping element 600 during the depression of the pressure lever 270, is smaller than a second damping force of a second movement state, which is a movement state of the damping element 600 after the release of the pressure lever 270, opposite to the movement direction of the first movement state.

Example 5

This embodiment may be a further improvement and/or a supplement to embodiments 1, 2, 3, 4 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 container may include an inner tub 100, a pressing lever 270, and a return spring 300. The return spring 300 can assist the pressing rod 270 in returning. 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 strut 270 is provided with a pedal, which may also be provided with a slip-resistant slot to allow a foot or hand to apply force to the strut 270.

Preferably, when the first inner tub 110 is mounted to the outer tub, a portion of the first inner tub 110 located below the first elastic sheet 111 is fixedly connected to an inner wall of the outer tub. 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 outer tub. For example, the mounting portion 112 is a raised edge that is fastened to the inner wall of the tub 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 outer barrel, the first inner barrel 110 is directly clamped on the boss, and then the first inner barrel 110 and the boss are fixedly connected by bolts penetrating through the barrel wall of the outer barrel 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 formed of a bottom chassis 400 provided in the second inner tub 120. The bottom chassis 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 conventional container inner tub 100, i.e., a fixed bottom, the fixed bottom moves downward along with the downward movement of the second inner tub 120, resulting in a limited ability to compress the loaded objects. Preferably, the central portion of the bottom plate 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 bottom plate 400 is provided with a first brush extending upward and obliquely, and the bristles of the first brush extend out of the bottom plate 400. Accordingly, when the chassis 400 and the second inner tub 120 are relatively displaced, the loaded objects, the garbage bag and/or the garbage are prevented from being caught in the gap between the first inner tub 110 and the second inner tub 120, which may cause a non-smooth compression process, a breakage of the garbage bag or a breakage of the loaded objects. 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 may be set in advance in design, repeated pricking may damage the contained object in an extreme case. For example, when the trash can is used as a trash can, due to the different qualities and thicknesses of the trash bags, the straightened softer bristles may pierce some thinner trash bags in an extreme state, and liquid in the trash bags 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 container may further include a first link 210 and a second link 220 linked with the pressing lever 270. Preferably, when the pressing rod 270 is pressed downwards, the first connecting rod 210 can push the second inner barrel 120 to move upwards under the driving of the pressing rod 270, and the second connecting rod 220 can push the chassis 400 to move downwards under the driving of the pressing rod 270. Therefore, when the pressing rod 270 is pressed downwards, the second inner barrel 120 moves upwards, 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 to form an inlet for a loaded object, and the chassis 400 also moves downwards, so that the space for accommodating the object constructed by the chassis 400 and the second inner barrel 120 is enlarged, and more objects can be placed in the space. Preferably, when the pressing rod 270 is released, the first link 210 may pull the second inner barrel 120 to move downward by the return spring 300 and the pressing rod 270, and the second link 220 may push the bottom plate 400 to move upward by the return spring 300 and the pressing rod 270. Therefore, when the pressing rod 270 is released by foot or hand, the second inner barrel 120 moves downwards 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 towards the middle part, and meanwhile, the chassis 400 also moves upwards under the indirect action of the return spring 300, so that a clamping effect is formed on the loaded objects, the compression effect is improved, and in addition, because the accommodating space in the second inner barrel is reduced from two directions, a certain compression effect can be realized when the loaded objects are few.

According to an alternative embodiment, the first link 210 and the second link 220 may be directly coupled to the pressing rod 270 to be interlocked. 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 chassis 400, the other end of the first link 210 may be hinged to the pressing lever 270 and the hinge point and the pedal thereof are located at different sides of the first fulcrum 281 of the pressing lever 270, respectively, and the other end of the second link 220 may be hinged to the pressing lever 270 and the hinge point and the pedal thereof are located at the same side of the first fulcrum 281 of the pressing lever 270. Therefore, when the pressing rod is pressed down, the pressing rod 270 drives the first connecting rod 210 to push the second inner barrel 120 upwards and drives the second connecting rod 220 to pull the bottom plate 400 downwards.

According to another alternative embodiment, the first link 210 and the second link 220 may be indirectly coupled to the pressing rod 270 to perform the linkage. For example, the first container may further include 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 chassis 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 pressing rod 270, and 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 connecting rod 210 and the second connecting rod 220 have other implementation manners linked with the pressing rod 270, so that when the pressing rod 270 is pressed downwards, the first connecting rod 210 can push the second inner barrel 120 to move upwards under the driving of the pressing rod 270, and the second connecting rod 220 can pull the chassis 400 to move downwards under the driving of the pressing rod 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 increase of the objects contained, the volume of the objects is continuously increased, the ascending space of the chassis 400 is limited, at this time, the second connecting rod 220 is compressed under the action of the chassis 400, so that more objects can be contained in the second inner barrel 120, and the elastic connection can also ensure that the second connecting rod 220 does not react with other connecting rods, so that the barrel 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 piece 121 is to pull the first elastic piece 111 downward to compress the contained object, the width of the second elastic piece 121 being smaller than the width 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 a preferred embodiment, the second elastic piece 121 may be provided with an anti-pinch member 140 for preventing an object from being pinched between the first elastic piece 111 and the second elastic piece 121.

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, an object can be prevented from being sandwiched between the first elastic sheet 111 and the second elastic sheet 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 object and the first elastic piece 111, and the anti-pinch layer is attached to the second elastic pieces 121 in a tubular shape when the first elastic pieces 111 are 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 barrel 100 is provided with a first viewing window 150 for viewing the position of the chassis 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. Thereby, the position of the chassis can be observed more clearly. When the compressed contents of the barrel reach the maximum volume, the bottom plate 400 is lowered to the lowest position through the first viewing window 150, so that the user knows that the container is full. For example, when the garbage can is used as a garbage can, a user can intuitively know that the garbage can is full, and at the moment, the pedal can be pressed down to open the can cover 520, so that a garbage bag filled with garbage can be taken out. Or, when the clothes storage container is used as a container for storing clothes, a user can quickly know that the container is full of clothes.

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 barrel 110 and the second inner barrel 120, so that it is more convenient to observe the position of the chassis 400.

According to a preferred embodiment, referring to fig. 4, a side of the first free end 111A of the first elastic sheet 111 and/or the second free end 121A of the second elastic sheet 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 an object in the process of the first elastic sheet 111 being converted from the bent state to the straightened state. For example, if the first and second free ends 111A and 121A are integrally formed in a sheet shape when the present invention is used as a trash can, it is likely that large, soft and light trash such as toilet paper and plastic packing bags on the top is caught and hung on the first and second free ends 111A and 121A, and even falls out of the inner tub 100, causing inconvenience to a 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 sheet 111 and the second elastic sheet 121 tearing objects during movement.

According to a preferred embodiment, the fifth link 250 for pushing the tub cover 520 is linked with the pressing lever 270, and when the pressing lever 270 is pressed, the fifth link 250 is pushed upward to open the tub cover 520, and when the pedal is released, the tub cover 520 is closed by its own 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 pressing lever 270. Alternatively, the fifth link 250 is indirectly connected to the pressing 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 pressing rod 270. Preferably, the fifth link 250 can be partially rotated in a plane in which the pressing lever 270 and the fifth link 250 are located while the other end of the fifth link 250 is hinged to the pressing 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 pressing lever 270 through the sixth link 260, the fifth link 250 can only slide up and down with respect to the tub 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. 1, 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 pressing rod 270 is loosened, the tub cover 520 may be closed under the gravity of itself, and the second inner tub 120 and the chassis 400 may be driven together with the return spring 300 by using the gravity 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 are provided with rubber buffering members. Preferably, in the case that rubber buffer elements are disposed at the edges of the tub cover 520 and the outer tub 510, an annular groove is disposed at the middle of a first rubber buffer element on the tub cover 520 along the edge of the tub 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 container may further comprise at least one damping element 600. One end of the damping element 600 may be hinged to the pressing rod 270, and the other end of the damping element 600 may be hinged to the outer tub. 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 movement state of the damping element 600, which is a movement state of the damping element 600 during the depression of the pressure lever 270, is smaller than a second damping coefficient of a second movement state of the damping element 600 after the release of the pressure lever 270, which is opposite to the movement direction of the first movement state. Different damping coefficients are set, so that large force is prevented from being required when the pressure lever 270 is pressed down, 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. Damping elements are known, such as shock absorbers, which can adjust the magnitude of the tensile and compressive damping coefficients, and therefore the structure of the damping element is not further limited herein.

According to an alternative embodiment, referring to fig. 1 again, the damping element 600 and the return spring 300 are respectively disposed at two sides of the first fulcrum 281 of the pressing rod 270, one end of the damping element 600 is hinged to the pressing rod 270, and the other end of the damping element 600 is hinged to the bottom 530 of the outer tub.
