Description
Technical Field
[0001] The utility model relates to a garbage can, in particular to a simple compression garbage can. 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. For some fluffy garbage, such as napkins, office waste paper, foam, plastic bags and other garbage, when they 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. This not only increases the frequency of replacing garbage bags and discarding garbage, but also the garbage bags cannot be fully and effectively used, so there are problems of environmental protection and waste. How to effectively compress the garbage in the trash can and minimize the space occupied by the garbage is the demand of the trash can industry.
[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 needs to cooperate with the added axial guide groove, the structure is complex, and the production cost is high; the axial guide groove is directly exposed in the trash can and is easily interfered by the garbage and debris inside. In actual operation, the compression mechanism often cannot be pressed down evenly and evenly, resulting in being stuck during operation, which is extremely inconvenient whether it is pressed down or reset.
[0004] The Chinese patent application number 2016102253583 discloses another trash can that can compress garbage. A pressure rod with a pressure plate is added to the trash can. The pressure rod is driven by a gear rack to drive the pressure plate downward to compress the garbage. The gear is driven by a lever and connecting rod mechanism installed outside the trash can. The problem with this technology is that both the gear rack and connecting rod transmission are exposed, which is easy to be contaminated and easily interfered by the outside world, which is not conducive to daily use. In addition, the gear rack and connecting rod transmission structure is complex, the cost is high, and the assembly and maintenance are very inconvenient. Summary of the invention
[0005] The purpose of the utility model is to provide a simple compression trash can with simple structure, low cost, stable control and convenient use according to the shortcomings of the prior art.
[0006] The purpose of the utility model is achieved through the following ways:
[0007] A simple compressed trash can comprises a trash can body for holding trash, the body having at least four side walls, the structural key points of which are that at least one side wall is divided into two parts, the lower part being the lower wall; the upper part being a pressing plate that can be flipped toward the inside of the body, the flipping angle being not less than 80 degrees, the lower edge of the pressing plate being hinged to the lower wall, and the height of the pressing plate being less than the distance between the side wall on which it is located and the opposite side wall.
[0008] When the garbage needs to be compressed, the pressing plate turns toward the space inside the barrel body with the hinge point as the fulcrum, and compresses the garbage downward in the space inside the barrel body; when the compression operation is not in progress, the pressing plate stands on the lower barrel wall, and becomes a part of the barrel body as a side barrel wall. Therefore, the utility model uses the upper part of the barrel wall as the pressing plate, so that the pressing plate is both a component for compressing the garbage and a part of the barrel wall, thereby greatly simplifying the structure, so that there are fewer parts, a simple structure, low cost, stable pedal control, and convenient use.
[0009] The utility model can be further specified as follows:
[0010] It also includes a pressing plate operating mechanism, which is connected to the pressing plate and can drive the pressing plate to flip toward the inner space of the barrel.
[0011] The pressure plate operating mechanism is used to drive the overturning, thereby compressing the garbage.
[0012] The pressing plate operating mechanism is a handle which is fixedly mounted on the outer side of the pressing plate; a resetting device is arranged at the hinge between the pressing plate and the lower barrel wall.
[0013] In this way, when the garbage needs to be compressed, the handle is grasped by hand to apply force to the pressure plate, so that the pressure plate turns inward and compresses the garbage with the pressure plate; after the compression is completed, the handle is released, and the pressure plate is returned to the upper half of the barrel by relying on the reset device. Of course, the pressure plate can also be reset by grasping the handle and pulling it upward.
[0014] The pressure plate operating mechanism is a foot-operated mechanism, comprising a foot pedal, a connecting component and a reset device. The foot pedal is hingedly mounted on the bottom of the barrel body, and the connecting component is respectively connected to the foot pedal and the pressure plate; the reset device is mounted on at least one of the foot pedal and the pressure plate; when the foot pedal is stepped on, the connecting component drives the pressure plate to flip toward the inner space of the barrel body.
[0015] When compressing garbage, step on the pedal with your foot to rotate the front end of the pedal downward. At the same time, the pedal drives the pressure plate to flip inward through the connecting parts, and compresses the garbage through the pressure plate. After the compression is completed, release the pedal, and the pedal returns to its original position with the help of the reset device. The pressure plate returns to the upper part of the lower barrel wall and serves as the side barrel wall together with the lower barrel wall. The pressure plate uses the pedal linkage connecting parts to operate its flipping, and uses the reset device to reset it. The pedal control is stable, the structure is simple, and it is more convenient and hygienic to use.
[0016] The connecting component may have multiple solutions, specifically:
[0017] The connecting component is a push rod, one end of which is hinged to the rear end of the foot pedal, the treading surface is located at the front end of the corresponding foot pedal, and the hinge point between the foot pedal and the bottom of the barrel body is located in the middle area of the bottom of the barrel body; the other end of the push rod is hinged to the connecting plate at the hinge between the pressure plate and the lower barrel wall.
[0018] In this way, when the tread surface of the foot pedal is stepped on, the rear end of the foot pedal is tilted upward, thereby pushing the push rod upward, further lifting the connecting plate backward and upward, so that the pressing plate is turned inward and downward, thereby completing the operation of compressing the garbage.
[0019] The connecting component is a pull rope, at which point cams are symmetrically arranged on both sides of the pressure plate, and connecting cams are symmetrically arranged on both sides of the front end of the foot pedal close to the treading surface, and the hinge point between the foot pedal and the bottom of the barrel body is located at the rear end; there are two groups of pull ropes, both of which are in a taut state, and each group is fixed to the connecting point cam at one end on the same side, and the other end is fixed to the connecting cam.
[0020] When the pedal is stepped on, the connecting cam will drop down, and the clamping point cam will also move downward under the action of the pull rope, thereby pulling the pressure plate to flip downward to complete the garbage compression operation. The pull ropes are symmetrically distributed on both sides of the barrel, so that during operation, the force on the garbage can is relatively balanced, and it will not swing left and right, making the compression process more stable. The pull rope can also be replaced by a rigid pull rod, such as a metal pull rod or a plastic pull rod.
[0021] The drawstring can be located inside or outside the barrel. When it is located outside the barrel:
[0022] Arc guide grooves are arranged on the two side barrel walls adjacent to the pressure plate on the left and right sides, and the clamping point convex shaft on the pressure plate passes through the arc guide grooves and is outside the barrel body, and the curvature of the arc guide grooves adapts to the movement curvature of the clamping point convex shaft when the pressure plate is flipped; at the same time, vertical guide grooves are arranged at the positions corresponding to the pedal connecting convex shafts under the two side barrel walls, and the connecting convex shaft on the foot pedal passes through the vertical guide grooves; two sets of pull ropes are symmetrically distributed on the two outer sides of the barrel body, and are respectively connected to the clamping point convex shaft on the pressure plate and the connecting convex shaft on the foot pedal.
[0023] In this way, under the constraints of the arc guide groove and the vertical guide groove, the force on the pull rope can be more stable and the compression process can be smoother.
[0024] The arc-shaped guide groove and the vertical guide groove are either located on the two sides of the central axis of the side barrel wall, or on the same side of the central axis of the side barrel wall.
[0025] When located on both sides of the central axis of the side barrel wall, the arc guide groove and the vertical guide groove are distributed in the upper left and lower right, or in the upper right and lower left; when located on the same side of the central axis of the side barrel wall, they are distributed in the upper left and lower left, or in the upper right and lower right. Preferably, the arc guide groove and the vertical guide groove are located on both sides of the central axis of the side barrel wall to provide a more stable force relationship.
[0026] The utility model can be further specified as follows:
[0027] The reset device may be a card point card slot structure, an elastic pin structure, an elastic soft rubber structure, or a torsion spring.
[0028] The main purpose of the reset device is to return the inwardly turned pressure plate to the upper part of the side barrel wall and stably stand on the upper part of the barrel wall, or to stably return the foot pedal to the position before being stepped on. When the reset device is installed alone on the pressure plate, it is used to reset the pressure plate, and the connecting component is linked to drive the foot pedal to reset. When the pressure plate is reset, it forms a complete side barrel wall with the lower barrel wall; when the reset device is installed alone on the foot pedal, it is used to reset the foot pedal, that is, return to the position before stepping on it, and the connecting component is linked to drive the pressure plate to reset; the reset device can also be installed on both the foot pedal and the pressure plate, so that both can be reset without driving, thereby improving the reliability of operation.
[0029] The card point card slot structure and the elastic pin structure are to apply another force to make them produce elastic deformation to reset the pressure plate, while the elastic soft rubber structure and the torsion spring rely on their own elastic force to automatically reset the pressure plate. Here, the torsion spring with the simplest structure is preferably used. When the torsion spring is installed on the pressure plate and the foot pedal, the power required for the reset of each component can be dispersed, which is beneficial to the design of the torsion spring and the balance of the trash can when it is reset. The inertia of the pressure plate when resetting will not be too large, and the strength of the upper half of the barrel body does not need to be too high, which is beneficial to the design of the barrel body.
[0030] A connecting mechanism for clamping or hanging the bag mouth of the garbage bag is installed on the outer side surface of the pressure plate. At the same time, a connecting mechanism is also arranged on the outer side surface of the opposite side barrel wall of the pressure plate, and vertically opening concession grooves are arranged on both sides of the upper part of the opposite side barrel wall. The bag mouth of the garbage bag is located on both sides of the pressure plate and the opposite side barrel wall, which are turned outward and clamped or hung by the connecting mechanism; and the other two sides are respectively passed through the concession groove and the gap between the two sides of the pressure plate and the adjacent side barrel wall and are located on the inner side of the barrel mouth of the barrel body.
[0031] In this way, after the garbage bag is installed, the two sides of the garbage bag are restricted by the connection mechanism and cannot fall off, while the other two sides are located on the inner side of the barrel mouth through the gap between the two sides of the pressure plate. When the pressure plate is operated, when the pressure plate is turned 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, thereby ensuring the cleanliness of the barrel body and preventing the hinged parts from being contaminated by the garbage.
[0032] 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.
[0033] 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.
[0034] In summary, the utility model provides a simple compression trash can, which uses the upper part of at least one side of the bucket wall as a pressure plate without adding a compression mechanism, and is operated by applying external force. It has the characteristics of simple and reliable structure, low cost and easy use. Using the side of the trash can body as a pressure plate can not only simplify the structure, but also greatly improve the utilization rate of the trash can space. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] The utility model is further described below in conjunction with embodiments. DETAILED DESCRIPTION
[0055] Embodiment 1:
[0056] Reference Figure 1-3As shown in 10-12, a simple compression trash can comprises a trash can body 1 for holding trash, the body 1 having at least four side walls (if the body is cylindrical, the outer circumference can be divided into four equal parts and regarded as four side walls). In this embodiment, a four-sided body is taken as an example, and at least one side wall is divided into two hinged upper and lower parts, wherein the upper part is a pressure plate 2 that can be flipped inward as a whole, and the lower part is a lower wall. In specific implementation, the upper parts of the two opposite side walls can be used as pressure plates, that is, two pressure plates, or more pressure plates can be used, so as to facilitate selection of a more convenient operating position in multiple directions. In this embodiment, one pressure plate is used, that is, one of the four side walls is used to set the pressure plate, and the side wall on the long side is preferred, and the height of the pressure plate is 50%-80% of the width of the body.
[0057] The pressing plate 2 is hinged to the hinge hole 11 of the lower barrel wall through the rotating shaft 21 (of course, the pressing plate 2 can also be connected in a soft rubber transition manner to support the pressing plate to flip relative to the lower barrel wall with the connected side, which will not be described in detail in this embodiment), and is located above the lower barrel wall in an upright state, and forms a side barrel wall with the lower barrel wall, and the side barrel wall is consistent with the height of the other three side barrel walls of the barrel body 1. The advantages of this design are: first, the shape of the barrel body 1 can be kept relatively intact; second, when compressing garbage, the barrel walls on the left and right sides will support the garbage, so that the garbage is kept inside the barrel body 1 and will not fall out from the left and right sides. Of course, the side barrel wall with the pressing plate can also be higher than the other three side barrel walls. It can be seen that the pressing plate 2 described in the utility model is used as a compression mechanism for compressing garbage, and is also used as a part of the barrel wall of the barrel body 1. This design makes the structure of the entire garbage can simpler, and when compressing garbage, the operating space is larger and it is more convenient to use.
[0058] The barrel body 1 is also provided with a reset device, which is used to automatically reset the pressure plate 2 after it is flipped inward and return it to the upper part of the barrel wall. There are many reset devices. This embodiment uses a torsion spring with a simple structure as the reset device, that is, a pressure plate torsion spring 22 is provided at the hinge between the pressure plate 2 and the lower barrel wall, which is used to return the pressure plate 2 to the upper half of the barrel body 1.
[0059] In this embodiment, in order to make the compression of garbage more convenient, a handle 232 can also be provided on the pressing plate 2 as a pressing plate operating mechanism to provide a better experience. When the garbage needs to be compressed, the handle 232 is grasped by hand and force is applied to the pressing plate 2 to flip the pressing plate 2 inward and use the pressing plate 2 to compress the garbage; after the compression is completed, the handle 232 is released and the pressing plate 2 is returned to the upper half of the barrel body 1 by relying on the pressing plate torsion spring 22. Of course, the pressing plate 2 can also be reset by grasping the handle 232 and pulling it upward, which will not be described in detail here.
[0060] In order to better install the garbage bag in combination with the pressure plate structure, the present embodiment adds a clamping plate 23. Figure 1-3 Based on reference Figure 6The pressing plate 2 is located at the rear side of the barrel body 1, and its opposite side is the front side barrel wall of the barrel body 1. In order to better fix the garbage bag 3 on the opening of the garbage can, a clamping plate 23 and a clamping plate torsion spring 231 are provided on the upper part of the front side barrel wall and the pressing plate 2, which are used to clamp the opening 31 of the garbage bag. The lower part of the clamping plate 23 is hinged to the upper part of the front side barrel wall and the outer surface of the pressing plate 2, and the clamping plate torsion spring is arranged at the hinge. Relying on the torsion of the clamping plate torsion spring 231, the clamping plate 23 firmly fixes the opening 31 of the garbage bag on the front side barrel wall and the pressing plate 2, so that during the garbage compression process, the garbage bag 3 will not fall off easily, causing the garbage to scatter. Two upper openings are also provided on both sides of the upper part of the front side barrel wall to avoid the opening 31 of the garbage bag. When installing the garbage bag 3, the front side of the garbage bag opening 31 passes through the give way groove 12 and goes around the front end face of the front side barrel wall. The rear side of the garbage bag opening 31 passes through the gap between the pressing plate 2 and the adjacent two side barrel walls and goes around the rear end face of the pressing plate. The front and rear sides of the garbage bag opening 31 are clamped by the clamping plate 2. The left and right sides of the garbage bag opening 31 are straightened and located on the inner side of the left and right sides of the barrel opening, and the installation of the garbage bag 3 is completed. In this way, when compressing the garbage, the pressing plate 2 brings the rear side of the garbage bag 3 to compress the garbage downward; and after the compression is completed, the pressing plate 2 brings the garbage bag 3 back to the upper half of the barrel body 1, and the garbage bag opening 31 remains open. This design makes the pressing plate 2 not easy to get dirty, keeps the garbage can clean, and the garbage bag 3 is not easy to interfere with the compression process. Of course, the clamping plate structure here can also be changed to a hook structure or a slot structure to fix the bag opening of the garbage bag, which is not described in detail in this patent.
[0061] The parts not described in the present invention are the same as those in the prior art.
[0062] Embodiment 2:
[0063] This embodiment uses a foot pedal mechanism as the pressure plate operating mechanism. Figure 4-12 The barrel body 1 is also provided with a reset device, a foot pedal 13 and a connecting component. The foot pedal 13 is hinged to the bottom of the barrel body 1. The reset device is used to automatically reset the pressure plate 2 after turning inward and return it to the upper part of the barrel wall where it is located. It is also used to reset the pedal that is stepped on. There are many reset devices. This embodiment uses a torsion spring with a simple structure as the reset device. The torsion spring can be set at the pressure plate 2, can be set at the foot pedal 13, or can be set at both places. In this embodiment, torsion springs are set at both the pressure plate 2 and the foot pedal 13, that is, a pressure plate torsion spring 22 is set at the hinge of the pressure plate 2 and the lower barrel wall, and a foot pedal torsion spring 131 is also set at the hinge of the foot pedal 13 and the bottom of the barrel body. The method of setting torsion springs at both places 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 garbage can when it is reset. The inertia of the pressure plate 2 when resetting will not be too large, and the strength of the upper half of the barrel body 1 does not need to be too high, which is beneficial to the design of the barrel body 1.
[0064] In this embodiment, a push rod 14 is selected as a connecting component. The lower end of the push rod 14 is hinged to the rear side of the foot pedal 13, and the upper end of the push rod 14 is hinged to the connecting plate 26 at the lower end of the pressing plate 2. The push rod 14 and its connecting part are located at the rear side of the barrel body 1. The foot pedal 13 is hinged to the bottom of the barrel body and is located between the treading surface and the connecting point of the push rod 14, close to the treading surface. When compressing garbage, step on the front treading surface of the foot pedal 13 with your foot, so that the front treading surface rotates downward, and at the same time, the connecting point of the push rod 14 and the foot pedal 13 is lifted upward, so that the push rod 14 pushes up the connecting part 26 of the pressing plate 2, and the pressing plate 2 is turned into the barrel body at the hinge part of the pressing plate 2. Thus, the foot pedal 13 drives the pressing plate 2 to turn inward through the push rod 14 as a connecting component, and the pressing plate 2 is used to compress the garbage. After the compression is completed, the foot pedal 13 is released, and the foot pedal returns to its position by relying on the foot pedal torsion spring 131, and the pressing plate 2 is retreated to the upper half of the lower barrel wall by relying on the torsion spring 22 of the pressing plate.
[0065] In this embodiment, if Figure 6-7 As shown, in order to facilitate the removal of garbage, the trash can is also equipped with a pressure plate decorative cover 24, which is hinged on the lower barrel wall together with the pressure plate 2, located on the inner side of the pressure plate and the lower barrel wall, and the pressure plate decorative cover 24 covers the rotating shaft 21 and the pressure plate torsion spring 22, so that the inner side of the pressure plate 2 and the barrel wall of the barrel body 1 remain flat, and the garbage bag 3 will not be scratched when taking out garbage. This embodiment can also be provided with a clamping plate 23, which is basically the same as that of embodiment 1 and will not be repeated.
[0066] The parts not described in this embodiment are the same as those in Embodiment 1.
[0067] Embodiment 3:
[0068] Refer to the attached Figure 10-18This embodiment also uses a pedal mechanism as the pressure plate operating mechanism, wherein the connecting component uses a pull rope 15, and the pull rope 15 is divided into two groups, which are symmetrically distributed on the left and right sides of the barrel body 1. At this time, the pressure plate is symmetrically provided with a clamping point convex shaft 25 on both sides, and the front end of the foot pedal close to the treading surface is symmetrically provided with a connecting convex shaft 132 on both sides, and the hinge point between the foot pedal and the bottom of the barrel body is located at the rear end; the lower end of the pull rope 15 is fixedly connected to the connecting convex shaft 132 on both sides of the foot pedal 13, and the upper end of the pull rope 15 is fixedly connected to the clamping point convex shaft 25 on both sides of the pressure plate 2. The design of using two pull ropes makes the force on the garbage can relatively balanced when compressing garbage, and it will not swing left and right, making the compression process more stable. The pull rope 15 can be installed in the interlayer set in the side barrel wall, or it can be exposed on the outer side of the barrel body. At this time, arc-shaped guide grooves are set on the two side barrel walls adjacent to the pressure plate 2 on the left and right, and the card point cam 25 on the pressure plate passes through the arc-shaped guide grooves. The curvature of the arc-shaped guide grooves is adapted to the movement curvature of the card point cam 25 when the pressure plate is flipped; at the same time, vertical guide grooves are set at the positions of the foot pedal connecting cam 132 below the two side barrel walls, and the connecting cam 132 on the foot pedal passes through the vertical guide grooves; two groups of pull ropes are symmetrically distributed on the two outer sides of the barrel body, and are respectively connected to the card point cam 25 on the pressure plate and the connecting cam 132 on the foot pedal.
[0069] like Figure 17-18 When compressing garbage, the user steps on the pedal 13 to rotate the front end of the pedal 13 downward. At the same time, the pedal 13 drives the pressing plate 2 to turn inward through the pull rope 15 as a connecting component, and the pressing plate 2 is used to compress the garbage. After the compression is completed, the pedal 13 is released, and the pedal returns to its original position by relying on the pedal torsion spring 131, and the pressing plate 2 returns to the upper half of the barrel body 1 by relying on the pressing plate torsion spring 22.
[0070] The parts not described in this embodiment are the same as those in Embodiment 2.
[0071] If this patent discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using an injection molding process) (except when it is obviously impossible to use an one-piece molding process).
