Description

Technical Field

[0001] The utility model relates to a garbage can, in particular to a garbage can with garbage compressed by foot. Background Art

[0002] As an indispensable necessity in life, trash cans are mainly used to dispose of garbage and waste. However, the capacity of trash cans in life is limited. When some fluffy garbage, such as napkins, office waste paper, foam, plastic bags, etc., are thrown into the trash can, a large number of gaps will be formed in the trash can, making it difficult for the trash can to accommodate more garbage, which increases the frequency of replacing garbage bags and discarding garbage, and the garbage bags cannot be fully and effectively used, so there are problems of environmental protection and waste.

[0003] In order to solve the above problems, the prior art adopts a mechanism for compressing garbage in the trash can. For example, in the Chinese patent with application number 2018200818201, a compression mechanism that can move up and down in the axial guide groove is added in the trash can. The compression mechanism uses a compression handle to push the compression frame to move downward along the axial guide groove to compress the garbage. The problem with this technology is that the compression handle is a manually operated control, which is not in line with the living habits and is not hygienic. Moreover, it is difficult to balance the force on both sides during manual operation, so it is difficult to push the compression frame downward in a balanced manner, and it is easy to get stuck in the middle, and it takes a lot of force to return, which is extremely inconvenient to use; the compression handle needs to cooperate with the additional axial guide groove, and the structure is complex, which occupies space in the bucket and has high production costs; the axial guide groove is directly exposed in the trash can, and it is easy to be interfered by the garbage and debris inside, resulting in being stuck during operation, which is extremely inconvenient whether it is pressed down or reset. Summary of the invention

[0004] The utility model aims to provide a garbage bin for compressing garbage with a foot, which has a simple structure, stable and reliable operation, low cost, and is clean and convenient to use, in view of the deficiencies in the prior art.

[0005] The purpose of the utility model is achieved through the following ways:

[0006] A trash can for pedal-operated garbage compression comprises an outer barrel body and an inner barrel body placed in the inner cavity of the outer barrel body; the inner barrel body for containing the garbage has at least four side barrel walls, and its structural key point is that at least one side barrel wall is divided into two hinged upper and lower parts, wherein the upper part is a pressure plate that can be flipped inward, and the lower part is a lower barrel wall; it also comprises a pedal mechanism, a swing mechanism and a reset device, the pedal mechanism is hingedly installed on the bottom of the outer barrel body, the swing mechanism comprises a swing rod and a connecting piece, one end of the swing rod is hingedly installed on the inner side surface of the outer barrel body corresponding to the position of the pressure plate, and the other end is close to or touches the outer side surface of the pressure plate, one end of the connecting piece is connected to the pedal mechanism, and the other end is connected to the swing rod; the reset device is installed at the connection between the pressure plate and the lower barrel wall, and the reset device is also installed on at least one of the pedal mechanism and the swing rod.

[0007] Therefore, when compressing garbage, the foot is stepped on the pedal mechanism to rotate the pedal mechanism downward. At the same time, the pedal mechanism drives the swing rod to rotate inward and downward through the connecting piece, and the swing rod further applies force to the pressure plate to make the pressure plate flip inward, so as to compress the garbage through the pressure plate. After the compression is completed, the pedal mechanism is released, and the pedal mechanism and the swing rod are respectively returned to their positions by the reset device, and the pressure plate is returned to the upper part of the lower barrel wall and together with the lower barrel wall, it serves as the side barrel wall of the inner barrel body. The utility model combines the structures of the inner and outer barrel bodies, firstly, part of the barrel wall of the inner barrel body is used as the pressure plate, so that the pressure plate is both a component for compressing garbage and a part of the barrel wall, which greatly simplifies the structure and does not occupy the space for accommodating garbage; secondly, the swing mechanism and the pedal mechanism used for the compression component are installed on the outer barrel body. On the one hand, the pedal operation conforms to the living habits and is hygienic and convenient to use. On the other hand, the structure is simple, no guide groove is required, and it does not interfere with the placement of garbage in the barrel. Therefore, the operation is stable and reliable, and the structure is simple and the cost is low.

[0008] The connecting piece of the utility model can be further specifically:

[0009] The connecting member is either a rigid thin rod or a pull rope, one end of which is connected to the front end of the foot pedal mechanism. In this case, the hinge point between the foot pedal mechanism and the bottom of the outer barrel is located at the rear end of the foot pedal mechanism; the other end is connected to the side of the swing rod that is close to the pressure plate and faces upward; in this case, the connecting member is arranged in two groups, and when the swing rod corresponds to one pressure plate, the two groups of connecting members are symmetrically distributed on both sides of the swing rod; when the swing rod corresponds to two symmetrically distributed pressure plates, the two groups of connecting members are respectively connected to the two swing rods.

[0010] The rigid thin rod can be a metal thin rod or a plastic thin rod. Furthermore, a hole is provided on the front end of the pedal mechanism, and the end of the rigid thin rod can be bent and hooked in the hole, and the pull rope can be tied and fixed in the hole. Alternatively, convex shaft clamping points are provided on both sides of the front end of the pedal mechanism, and the end of the rigid thin rod is bent into a ring and can be sleeved on the convex shaft clamping point, or is hinged to the convex shaft clamping point, and the pull rope can be tied and fixed on the convex shaft clamping point.

[0011] When the connecting piece is used as a thin rod or a pull rope, a pulling force is generated on it when the pedal mechanism is stepped on, thereby pulling the swing rod to rotate inward and downward to drive the pressure plate to flip. The symmetrical distribution method can improve the force balance and make the operation more stable and reliable.

[0012] The connecting piece is a push rod, one end of which is hinged to the rear end of the pedal mechanism, the treading surface of the pedal mechanism is the front end, and the hinge point between the pedal mechanism and the bottom of the outer barrel is located on the side of the middle part close to the front end; the other end of the push rod is hinged to the connecting plate at the hinge between the swing rod and the outer barrel.

[0013] At this time, when the pedal mechanism is stepped down, an upward force is generated on the push rod, that is, the rear end of the pedal mechanism is tilted upward, thereby pushing the push rod upward, and further lifting the connecting plate backward and upward, so that the swing rod flips forward and downward, thereby driving the pressing plate to complete the operation of compressing the garbage.

[0014] The utility model can be further specified as follows:

[0015] The swing rod is an H-shaped structure, with the upper and lower parts being bent at obtuse angles, with the inner angle of the bend facing the pressure plate, the upper part touching the outer surface of the pressure plate, and the lower part being hinged on the inner surface of the outer barrel body; a convex piece is arranged in the middle, and one end of the connecting piece is connected to the convex piece.

[0016] The swing arm can be a single-rod structure, a double-rod structure or a multi-rod structure. The H-shaped structure is preferred, which can provide a more stable flipping requirement, and the swing arm with a bent structure can drive the pressure plate to provide more rotation angles.

[0017] The reset device may be a card point card slot structure, an elastic pin structure, an elastic soft rubber structure, or a torsion spring.

[0018] The card point card slot structure and the elastic pin structure are used to apply additional force to cause elastic deformation so that the pressure plate can be reset, while the elastic soft rubber structure and the torsion spring rely on their own elastic force to automatically reset the pressure plate. Here, it is preferred to use a torsion spring with the simplest structure. When the reset device is installed separately on the swing rod, the reset of the swing rod can be linked to the connecting piece to drive the pedal mechanism to reset; when the reset device is installed separately on the pedal mechanism, the reset of the pedal mechanism can be linked to the connecting piece to drive the swing rod to reset. The preferred solution is to install torsion springs on both the swing rod and the pedal mechanism as reset devices, which can disperse the power required for the reset of each component, which is beneficial to the design of the torsion spring and the balance of the trash can when it is reset.

[0019] When there is only one pressing plate, a connecting mechanism for clamping or hanging the bag mouth of the garbage bag is installed on the outer side surface of the pressing plate. At the same time, a connecting mechanism is also arranged on the outer side surface of the barrel wall opposite to the pressing plate, and vertically opening giving way grooves are arranged on both sides of the upper part of the barrel wall opposite to the pressing plate. The bag mouth of the garbage bag is located on both sides of the pressing plate and the barrel wall opposite to the pressing plate, and is turned outward and clamped or hung by the connecting mechanism; and the other two sides are respectively located on the inner side of the barrel mouth of the inner barrel body through the giving way groove and the gap between the two sides of the pressing plate and the adjacent barrel wall.

[0020] When the pressing plates are arranged to be two symmetrical ones, a connecting mechanism for clamping or hanging the bag opening of the garbage bag is installed on the outer side surface of each pressing plate, and the bag opening of the garbage bag is located on both sides of the two pressing plates arranged opposite to each other, both of which are turned outward and clamped or hung by the corresponding connecting mechanism; and the other two sides respectively pass through the gaps between the two sides of the pressing plate and the adjacent side barrel walls and are located on the inner side of the barrel opening of the inner barrel body.

[0021] In this way, after the garbage bag is installed, the two sides of the garbage bag are restricted by the connecting mechanism and cannot fall off, while the other two sides are located on the inside of the barrel mouth. When operating the pressing plate, when the pressing plate flips inward and downward to compress the garbage, its lower pressing surface carries the garbage bag, so there is no need to directly contact the garbage, thus ensuring the cleanliness of the barrel body and preventing the hinged parts from being contaminated by the garbage.

[0022] The connecting mechanism is either a splint, the lower end of which is hinged on the outer side surface of the pressure plate and the upper part of the barrel wall opposite to it, with the clamping mouth facing upward; the connecting mechanism is either a hook or a slot, which is fixed on the outer side surface of the pressure plate and the upper part of the barrel wall opposite to it, and when it is a hook, the hook mouth faces downward and inward; when it is a slot, the clamping mouth faces downward.

[0023] The connecting mechanism is a device for clamping or hanging the opening of the garbage bag. It can have various forms, not limited to the above three situations, as long as it can effectively restrain the opening of the garbage bag.

[0024] The inner barrel body is either fixed inside the outer barrel body or is constructed as an independent module separately from the outer barrel body.

[0025] When the inner barrel body is separated from the outer barrel body, the inner barrel body can be separated from the outer barrel body, which is convenient for cleaning garbage and replacing garbage bags. At this time, an opening window is provided on the top of the outer barrel body, and the inner barrel body can be taken out from the top; or an outward opening door is provided on the side of the outer barrel body, and the inner barrel body can be taken out from the side.

[0026] In summary, the utility model provides a trash can for compressing garbage by foot. Combined with the structure of the inner and outer barrel bodies, on the one hand, the pressure plate is both a component for compressing the garbage and a part of the barrel wall of the inner barrel body, which greatly simplifies the structure and does not occupy the space for accommodating the garbage; on the other hand, the swing mechanism and the pedal mechanism for the compression component are installed on the outer barrel body. On the one hand, the pedal operation conforms to the living habits, is hygienic and convenient to use, is stable and reliable to operate, and has a simple structure and low cost.

[0040] The utility model is further described below in conjunction with embodiments. DETAILED DESCRIPTION

[0041] See attached Figure 1-12 A trash can for pedal-operated garbage compression includes an outer barrel 1 and an inner barrel 2 for holding garbage, and also includes a pedal mechanism 11, a swing mechanism and a reset device. The pedal mechanism 11 is hingedly mounted on the bottom of the outer barrel 1, and the swing mechanism includes a swing rod 12 and a connector. The inner barrel 2 has at least four side barrel walls (if the barrel is cylindrical, the outer circumference can be divided into four equal parts and regarded as four side barrel walls). This embodiment takes a four-sided barrel as an example and adopts a double pressure plate solution, that is, the two opposite side barrel walls are divided into two hinged upper and lower parts, the upper part of which is a pressure plate 21 that can be turned inward, and the lower part is a lower barrel wall. The height of each pressure plate 21 does not exceed half of the distance between it and the opposite side barrel wall. In specific implementation, one pressure plate can also be used, that is, one of the four side barrel walls is used to set the pressure plate, and the side barrel wall of the long side is preferred. The height of the pressure plate is 50%-80% of the barrel width. The pressing plate 21 is hingedly connected to its corresponding lower barrel wall via a rotating shaft 22 (the pressing plate 21 can also be connected by a soft rubber transition method, which is not described in detail here). When the pressing plate 21 stands above the lower barrel wall, it forms a side barrel wall with the lower barrel wall. Therefore, the pressing plate 21 is used as a pressing plate for compressing garbage and also as a barrel wall of the inner barrel 1. This design makes the structure of the entire inner barrel 2 simpler, and when compressing garbage, the operating space is larger and it is more convenient to use.

[0042] The reset device is a torsion spring, wherein the one installed at the hinge of the pressing plate 21 and the lower barrel wall is a pressing plate torsion spring 211, which is hinged on the lower barrel wall together with the pressing plate 21, and is used to automatically reset the pressing plate 21 after flipping inwards, so that the pressing plate 21 remains in an upright state. In addition, in order to keep the inner wall of the pressing plate 21 flat and not scratch the garbage bag 3, a pressing plate decorative cover 212 is provided on the pressing plate 21 to cover the pressing plate torsion spring 211 and the rotating shaft 22. The reset device installed on the pedal mechanism 11 is a pedal torsion spring, and the pedal mechanism 11 and the pedal torsion spring are hinged on the lower bottom pad 15 of the lower half of the outer barrel body 1. In this embodiment, the pull rope 13 is used as a connecting member, so the hinge point of the pedal mechanism 11 and the outer barrel body 1 is located at its rear end, and the front end is used as a pedal surface. The left and right sides of the pedal mechanism 11 near the front end are provided with holes or convex shaft clamping points for fixing one end of the pull rope 13. The reset device installed on the swing rod 12 is a swing rod torsion spring. The lower end of the swing rod 12 is hinged on the inner side of the outer barrel body. The number of the swing rods 12 is the same as the pressure plate 21, and they are installed on the corresponding side of the pressure plate 21. The swing rod 12 is an H-shaped structure, with an upper and lower bent structure with obtuse angles, and the inner angle of the bend is toward the pressure plate. The upper part is close to or touches the outer side of the pressure plate 21, and the lower part is hinged on the inner side of the outer barrel body 1. A convex piece is arranged in the middle, and the other end of the pull rope 13 is fixedly connected to the hole set on the convex piece. In order to further obtain stable operation, a plate surface vertically fixed to the inner side of the outer barrel body can also be arranged below the swing rod 12, and a limit hole for the pull rope 13 to pass through can be arranged on the plate surface. In this way, the swing rod 12 is symmetrically distributed and hinged on the left and right sides of the middle of the outer barrel body 1, and the pressure plate 21 is also symmetrically distributed on the left and right sides of the inner barrel body 2. The pedal mechanism 11 drives the swing rod 12 to swing through the pull rope 13. The inner barrel body 2 is placed inside the outer barrel body 1 and is located inside the swing rod 12 .

[0043] The outer surfaces of the left and right pressing plates 21 are provided with connection mechanisms capable of clamping or hooking the opening of the garbage bag. In this embodiment, a clamping plate 23 is selected as the connection mechanism. The lower end of the clamping plate 23 is hinged to the outer surface of the pressing plate 21 with the clamping plate torsion spring 24. The clamping plate 23 firmly fixes the opening 31 of the garbage bag on the outer surface of the pressing plate 21 by the torsion of the clamping plate torsion spring 24. The opening 31 of the garbage bag 3 is put on the left and right pressing plates 21, and the front and rear sides of the garbage bag 3 are straightened by the left and right pressing plates 21 and located inside the opening of the inner barrel 2, so that a garbage feeding port for putting in garbage is formed that is the same as the opening of the inner barrel 2. In this way, during the compression of garbage, the garbage bag 3 is not easy to fall off, causing the garbage to scatter, and the garbage bag 3 will not interfere with the compression process. When it is necessary to compress the garbage, the pedal mechanism 11 is stepped on with the foot to rotate the pedal mechanism 11 downward. At the same time, the pedal mechanism 11 drives the swing rod 12 to rotate inward through the connected pull rope 13, and the swing rod 12 applies force to the pressure plate 21, so that the pressure plates 21 on both sides of the inner barrel body 2 rotate inward and downward around the hinged rotating shaft 22, thereby compressing the garbage downward with the garbage bag 3. After the compression is completed, the pedal mechanism 11 is released, and relying on the torsion force of the torsion spring, the pedal mechanism 11 and the swing rod 12 return to their respective positions, and the pressure plate 21 returns to the upper half of the lower barrel wall with the garbage bag 3 in an upright state.

[0044] In this embodiment, the inner barrel body 2 can be fixed inside the outer barrel body 1, or it can be an independent module and a separate structure from the outer barrel body 1, such as Figure 2-5 As shown, in order to facilitate the removal of garbage, the inner barrel body 2 and the outer barrel body 1 described in this patent are split structures, and the inner barrel body 2 can be directly taken out together with the garbage, which is convenient for cleaning the garbage, and it is also more convenient to put on the garbage bag 3. Figure 1-4 As shown, the outer barrel body 1 is also provided with a door 14 that opens outwards, and opening the door makes it convenient to take out the garbage and clean up the garbage that is accidentally spilled and scattered.

[0045] The parts not described in the present invention are the same as those in the prior art.

[0046] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using an injection molding process) (except when it is obviously impossible to use an integral molding process).
