Description

Technical Field

[0001] This invention relates to the field of environmental protection, and in particular to a multifunctional intelligent plastic trash can for gardens. Background Technology

[0002] Trash cans, as the most commonly used facility for collecting garbage, are widely distributed in public environments, especially in parks with high traffic and scenic features. To facilitate garbage collection, existing trash cans usually have garbage bags inside. When collecting garbage, one only needs to pull out the garbage bag from the inside of the can, which is convenient, quick, and clean. However, due to the high traffic in parks, the amount of garbage in the garbage bags is large. When pulling out the garbage bags from conventional trash cans, the edges of the garbage bags are prone to breakage due to excessive force, which can easily cause garbage to scatter. In addition, the garbage bags tend to stick to the inner wall of the trash can. During the process of pulling out the garbage bags, they are easily pulled by the inner wall of the trash can, which can cause the garbage bags to break due to force, making garbage collection and cleaning inconvenient.

[0003] Furthermore, since the trash cans in the park mainly collect food and water discarded by tourists, the trash bags usually contain flowing liquids. This makes the trash bags prone to rupture under pressure during transportation, causing the liquid to spill everywhere, which is inconvenient for the collection and cleaning of liquid waste. Summary of the Invention

[0004] To overcome the shortcomings of conventional trash cans, such as the tendency for trash bags to break at the edges due to excessive force when being removed, the tendency for trash bags to stick to the inner wall of the trash can and thus be easily torn, hindering trash collection and cleaning, and the tendency for trash bags to break under pressure during transportation, causing liquid inside the trash bag to spill everywhere, making it difficult to collect and clean up liquid waste, this invention provides a multifunctional intelligent plastic trash can for gardens.

[0005] The technical implementation scheme of the present invention is as follows: a multifunctional intelligent plastic trash can for gardens, comprising a base and a fixing ring; a plurality of fixing rings are provided on the base; a plurality of support rods are provided on the lower side of the fixing rings; a trash bag is fitted inside the fixing rings; it also includes a protective bin, a lid, a connecting plate, and a separation system; a plurality of lifting protective bins are installed on the base to prevent damage to the trash bag; the protective bin is divided into a left part and a right part, and the left part and the right part are movably connected; a lid is movably connected to each protective bin; each lid is provided with an opening and closing part; an automatic sensor is installed on the opening and closing part; a connecting plate is provided between the plurality of protective bins; and a separation system for separating liquid inside the trash bag is provided on the base.

[0006] More preferably, the protective casing is made of thermoplastic material.

[0007] More preferably, it also includes pressure plates and slip rings; several pressure plates are rotatably connected to the upper side of the fixed ring to separate the garbage bag from the inner wall of the protective bin; a slip ring is slidably connected to the support rod of the same fixed ring; the inner wall of the protective bin is provided with protrusions, and when the protective bin moves upward, the protrusions on the inner wall of the protective bin contact and squeeze the slip ring.

[0008] More preferably, the diameter of the slip ring is set to be smaller than the diameter of the fixed ring.

[0009] More preferably, the separation system includes support rods, spikes, pedals, and a collection chamber; several support rods are movably connected to the inside of the base; each support rod is fixed with a spike for puncturing the garbage bag; the base has several drainage holes for separating liquid from the garbage bag, and each spike is located in an adjacent drainage hole; each support rod is fixed with a pedal; a collection chamber for collecting liquid from the garbage bag is installed on the lower inside of the base; the collection chamber is equipped with a suction port.

[0010] More preferably, the contact surface between the base and the garbage bag is set as a concave arc surface, and the drain hole is located at the lowest point of the concave arc surface.

[0011] More preferably, the pedal is located on the inside of the connecting plate.

[0012] More preferably, the collection compartment is designed to slide on the base.

[0013] More preferably, the opening and closing part of the lid is located near the middle of the base.

[0014] More preferably, a sealing strip is provided on the front side of each bucket lid.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] By controlling the protective bucket to move upward and opening the outside of the protective bucket, it is easier for sanitation workers to pull out the garbage bag, while avoiding damage to the edges of the garbage bag due to excessive force, which would cause the garbage to scatter and improve the efficiency of garbage collection.

[0017] By using thermoplastic as the material for the protective buckets, when the surface of the protective buckets becomes faded and yellowed due to aging, the surface can be refurbished at high temperatures to restore its shine, thereby beautifying the environment and improving the quality of the garden landscape. In addition, the plastic is lightweight and corrosion-resistant, making it easy for sanitation workers to clean the protective buckets.

[0018] The pressure plate pushes the garbage bag towards the center of the fixed ring, so that the part of the garbage bag in contact with the pressure plate is in a closed state, thereby separating the garbage bag from the inner wall of the protective bucket and preventing the protective bucket from pulling the garbage bag and causing it to break.

[0019] By moving the spikes upwards to puncture the garbage bag, the liquid inside the garbage bag flows downwards from the drain hole into the collection chamber, and the liquid in the collection chamber is collected through the suction port, thereby achieving the separation and collection of solid and liquid garbage in the garbage bag and improving the collection capacity of liquid garbage.

[0020] By sealing the gap between the lid and the protective barrel at the front, the airflow in the protective barrel is prevented from overflowing to the front, thus preventing visitors from smelling any odors inside the protective barrel and improving the garden sightseeing experience.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1

[0030] like Figures 2-4As shown, a multi-functional intelligent plastic trash can for gardens includes a base 1 and a fixing ring 2; two symmetrical fixing rings 2 are provided on the base 1; at least three support rods 2001 are provided on the lower side of the fixing rings 2; a trash bag 3 is fitted inside the fixing rings 2;

[0031] It also includes a protective bin 4, a bin lid 5, a connecting plate 6, and a separation system; two symmetrical protective bins 4 are installed on the base 1; the protective bins 4 are divided into left and right parts, and the left and right parts are movably connected. By controlling the protective bins 4 to move upward, the outer side of the protective bins 4 is opened, which makes it easier for sanitation workers to take out the garbage bags 3, while avoiding damage to the edges of the garbage bags 3 due to excessive force, which would cause garbage to scatter and improve garbage collection efficiency; a bin lid 5 is movably connected to each protective bin 4; each bin lid 5 is provided with an opening and closing part 5001; an automatic sensor is installed on the opening and closing part 5001, which realizes the automatic opening and closing of the bin lid 5 by recognizing the distance to people, which makes it convenient for tourists to dispose of garbage; a connecting plate 6 is provided between the two protective bins 4; a separation system is provided on the base 1, which separates and collects the liquid in the garbage bags 3, improving the collection capacity of liquid garbage.

[0032] The protective bucket 4 is made of thermoplastic plastic. When the surface of the protective bucket 4 becomes faded and yellow due to aging, its surface can be refurbished at high temperature to restore its shine, thereby beautifying the environment and improving the quality of the garden landscape. In addition, the plastic is lightweight and corrosion-resistant, making it easy for sanitation workers to clean the protective bucket 4.

[0033] It also includes a pressure plate 202 and a slip ring 203; four pressure plates 202 arranged in a ring are connected to the upper side of the fixed ring 2 by a torsion spring; a slip ring 203 is slidably connected to the support rod 2001 of the same fixed ring 2; the inner wall of the protective bucket 4 is provided with protrusions. When the protective bucket 4 moves upward, the protrusions on the inner wall of the protective bucket 4 contact and squeeze the slip ring 203, and push the garbage bag 3 towards the center of the fixed ring 2 through the pressure plate 202, so that the part of the garbage bag 3 in contact with the pressure plate 202 is in a closed state, thereby separating the garbage bag 3 from the inner wall of the protective bucket 4 and preventing the protective bucket 4 from pulling the garbage bag 3 and causing it to break.

[0034] The diameter of the slip ring 203 is set to be smaller than that of the fixed ring 2, so that the pressure plate 202 further pushes the garbage bag 3 towards the center of the fixed ring 2 and tightens it. This causes the part of the garbage bag 3 that is in contact with the fixed ring 2 to separate from the fixed ring 2, making it easier for sanitation workers to directly pick up the garbage bag 3 and tie it from the opening of the garbage bag 3 to prevent garbage from scattering and improve the collection efficiency of the garbage bag 3.

[0035] It also includes a drive component 201; the drive component 201 is fixedly connected to the upper side of the base 1, and the drive component 201 is an electric push rod; the telescopic end of the drive component 201 is fixedly connected to the connecting plate 6, and the drive component 201 drives the connecting plate 6 to move upward, thereby driving the two protective barrels 4 to move upward.

[0036] Before using the trash can, first control the drive unit 201 to move the connecting plate 6 upward, thereby moving the protective can 4 upward and detaching it from the base 1. Here, we will use the protective can 4 on the left side as an example for detailed explanation. At this time, open the left part of the protective can 4, then place the trash bag 3 onto the fixing ring 2, and then reset the protective can 4. Automatic opening and closing is achieved through the automatic sensor on the can lid 5, facilitating trash disposal. When it is necessary to remove the trash bag 3, control the protective can 4 to move upward, then open the left part of the protective can 4. At this time, the trash bag 3 and the large amount of trash inside are removed. Part of the weight is supported by the base 1. Sanitation workers only need to remove the garbage bag 3 from the fixing ring 2, and then pull the garbage bag 3 to the left to detach it from the base 1. This prevents the edges of the garbage bag 3 from breaking due to excessive force, thus preventing garbage from scattering and improving garbage collection efficiency. Furthermore, because the garbage bag 3 contains a lot of garbage, it easily adheres to the inner wall of the protective bin 4. When the protective bin 4 moves upward, it can easily pull the garbage bag 3, causing it to break. Therefore, when the protective bin 4 moves upward, the protrusions on the inner wall of the protective bin 4 drive the slip ring 203 to move upward. The slip ring 203 contacts and presses the pressure plate 202, causing the pressure plate 202 to rotate closer to the center of the fixed ring 2. This pushes the garbage bag 3 towards the center of the fixed ring 2, bringing the part of the garbage bag 3 in contact with the pressure plate 202 into a closed state. This separates the garbage bag 3 from the inner wall of the protective bucket 4, preventing the protective bucket 4 from pulling the garbage bag 3 and causing it to break. Furthermore, since the diameter of the slip ring 203 is smaller than the diameter of the fixed ring 2, as the protective bucket 4 continues to rise, the slip ring 203 contacts the fixed ring 2, causing the pressure plate 202 to further push the garbage bag 3. Tighten the ring towards the center of the fixing ring 2, thereby detaching the part of the garbage bag 3 that is in contact with the fixing ring 2 from the fixing ring 2. This makes it easier for sanitation workers to directly pick up the garbage bag 3 and tie it at the opening to prevent garbage from scattering and improve collection efficiency. In addition, the protective bin 4 is made of thermoplastic material. When the surface of the protective bin 4 becomes faded and yellow due to aging, its surface can be refurbished at high temperature to restore its shine, thereby beautifying the environment and improving the quality of the garden landscape. Furthermore, the plastic is lightweight and corrosion-resistant, making it easy for sanitation workers to clean the protective bin 4.

[0037] Example 2

[0038] Based on Example 1, such as Figure 5As shown, the separation system includes support rods 301, spikes 302, pedals 303, and a collection chamber 304. Two symmetrical support rods 301 are hinged to the inner side of the base 1. A spike 302 is fixed to each support rod 301. Two drainage holes 1001 are opened on the base 1, and each spike 302 is located in an adjacent drainage hole 1001. A pedal 303 is fixed to each support rod 301. A collection chamber 304 is installed on the lower inner side of the base 1. A suction port 30401 is provided on the collection chamber 304. By moving the spikes 302 upwards, the garbage bag 3 is punctured, allowing the liquid in the garbage bag 3 to flow downwards from the drainage holes 1001 into the collection chamber 304. The liquid in the collection chamber 304 is then collected through the suction port 30401, thereby achieving the separation and collection of solid and liquid waste in the garbage bag 3 and improving the collection capacity of liquid waste.

[0039] The contact surface between the base 1 and the garbage bag 3 is set as a concave arc surface 1002, and the drain hole 1001 is located at the lowest point of the concave arc surface 1002. The concave arc surface 1002 guides all the liquid in the garbage bag 3 to flow to the drain hole 1001, reducing the liquid residue in the garbage bag 3 and improving the solid-liquid separation efficiency.

[0040] The step 303 is located inside the connecting plate 6 to prevent tourists from accidentally touching it when disposing of garbage, thereby preventing the garbage bag 3 from being punctured multiple times, causing the hole to enlarge and reducing the load-bearing capacity of the garbage bag 3.

[0041] The collection bin 304 is designed to slide on the base 1, which makes it easy for sanitation workers to regularly pull the collection bin 304 out of the base 1 to clean the inner wall of the collection bin 304, ensuring that there are no dead corners in the trash can and avoiding the generation of odors.

[0042] Compared to regular trash cans, the trash cans in the park mainly collect food and water discarded by visitors. Therefore, the trash bags 3 typically contain flowing liquids. During transport, the trash bags 3 are easily squeezed together, causing them to break and the liquid to spill everywhere, hindering the collection and cleaning of liquid waste. Therefore, before handling the trash bags 3, the following detailed explanation is provided using the pedal 303 on the left as an example. When a sanitation worker steps on the pedal 303, looking from front to back, the support rod 301 rotates clockwise, causing the spikes 302 to move upwards. The upward movement of the spikes 302 punctures the trash bag 3, allowing the liquid inside to flow downwards from the drain hole 1001 into the collection chamber 304. The liquid is then collected in the collection chamber 304 through the suction port 30401, thus achieving the separation and collection of solid and liquid waste within the trash bag 3. The system boasts a high capacity for collecting liquid waste. Furthermore, because the drain hole 1001 is located at the lowest point of the concave surface 1002, the liquid inside the garbage bag 3 is guided to flow entirely to the drain hole 1001 via the concave surface 1002, reducing liquid residue inside the garbage bag 3 and improving solid-liquid separation efficiency. Additionally, during the cleaning of the inner wall of the protective bin 4, the concave surface 1002 collects the wastewater generated during cleaning, preventing wastewater from flowing out and polluting the environment. Moreover, because the pedal 303 is located inside the connecting plate 6, it prevents accidental contact by visitors when disposing of garbage, thus preventing the garbage bag 3 from being repeatedly punctured, leading to enlarged holes and reduced load-bearing capacity. Further, the collection bin 304 is designed to slide on the base 1, facilitating regular removal of the collection bin 304 from the base 1 by sanitation workers for cleaning the inner wall of the collection bin 304, ensuring no dead corners in the garbage bin and preventing odor generation.

[0043] Example 3

[0044] Based on Example 1, such as Figure 1 and Figure 6 As shown, the opening and closing part 5001 of the bucket lid 5 is located near the middle of the base 1. When the bucket lid 5 is about to fit against the protective bucket 4, the gap between the front and rear sides of the bucket lid 5 and the protective bucket 4 is smaller than the gap on the left side, thereby reducing the airflow that overflows from the front gap and reducing the odor that tourists smell.

[0045] Each bucket lid 5 is equipped with a sealing strip 5002 on the front side. The sealing strip 5002 blocks the gap between the bucket lid 5 and the protective bucket 4 on the front side, thereby preventing the airflow of the protective bucket 4 from overflowing to the front side, thus preventing tourists from smelling the odor inside the protective bucket 4 and improving the garden sightseeing experience.

[0046] Because the lid 5 draws some air into the protective bin 4 when it closes, the pressure inside the protective bin 4 is greater than the pressure outside when the lid 5 is about to close. This causes the air inside the bin to overflow along the gap between the protective bin 4 and the lid 5, allowing visitors to smell the odor inside the protective bin 4. To address this, the opening and closing part 5001 of the lid 5 is located near the middle of the base 1. When the lid 5 is about to close, the gap between the front and rear sides of the lid 5 and the protective bin 4 is smaller than the gap on the left side, thereby reducing the airflow overflowing from the front gap and reducing the odor that visitors smell. Furthermore, when the lid 5 is about to close, the sealing strip 5002 blocks the front gap between the lid 5 and the protective bin 4, preventing the airflow from overflowing to the front side of the protective bin 4, thus preventing visitors from smelling the odor inside the protective bin 4 and improving the garden sightseeing experience.
