Description

Technical Field

[0001] This utility model relates to the field of trash can technology, and more specifically, to an automatic fire-extinguishing trash can. Background Technology

[0002] Public trash cans are public facilities used to hold garbage and waste, and are commonly placed in outdoor public places such as parks, residential areas, and schools. Most trash cans in public areas are unattended, and fires are frequently caused by open flames or other flammable materials, often going undetected and posing a safety hazard.

[0003] Existing technology discloses a garbage bin with a fire extinguishing mechanism, including a bin body. A mounting bracket is fixedly connected to the upper end of the bin body. Second slide rails are fixedly connected to both sides of the mounting bracket's interior. Sliding blocks are slidably connected inside each of the second slide rails, and a rotating shaft is fixedly connected between the sliding blocks. In this prior art, a cover plate is bolted to the rear end of the mounting housing, and a carbon dioxide storage tank is bolted inside the mounting housing. When the carbon dioxide storage tank needs inspection, repair, or replacement, some bolts need to be loosened to remove the cover plate, and then some bolts need to be loosened to remove the carbon dioxide storage tank. The repair and replacement process for the carbon dioxide storage tank is cumbersome and time-consuming. Utility Model Content

[0004] To address the problem of time-consuming maintenance and replacement of gas storage tanks in the prior art, this invention provides an automatic fire-extinguishing trash can, which makes the maintenance and replacement of gas storage tanks simpler and faster.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows:

[0006] An automatic fire-extinguishing trash can includes a gas storage tank and a housing with a storage cavity. A gas nozzle is provided on the inner wall of the storage cavity, and the outlet end of the gas storage tank communicates with the gas nozzle. The housing has a storage slot, and also includes a drawer and an elastic element. The drawer is located within the storage slot, and a lock is provided on the outside of the drawer. The storage slot has a locking structure that cooperates with the lock, locking the drawer securely within the storage slot to prevent it from opening. The gas storage tank is located inside the drawer. The two ends of the elastic element are connected to the inner wall of the storage slot and the inner side of the drawer, respectively. It can be understood that the outer side of the drawer is the exposed side, and the inner side is the side opposite to the outer side.

[0007] The locking structure can be a latch located at the bottom of the storage slot. The box lock includes a pin and a linkage component. When the drawer is pushed into the storage slot, the linkage component drives the pin to engage with the latch, thus locking the drawer in place. Alternatively, the box lock can be a screw lock or a push-rod lock, with the locking structure corresponding to the box lock structure. The box lock can be opened or closed using a key. Such box locks and locking structures are existing technologies; therefore, this manual will not provide a more detailed explanation of their structure and principles.

[0008] In the above technical solution, under normal use, the drawer is locked in the storage slot by a lock. When maintenance or replacement of the gas storage tank is required, maintenance personnel only need to use a key to open the lock, which will release the lock from the locking mechanism. At this time, the drawer will pop out of the storage slot under the elastic force of the elastic element, allowing maintenance personnel to quickly access the gas storage tank for maintenance or replacement.

[0009] Preferably, slide rails are provided on both opposite sides of the storage slot, and raised strips are provided on both opposite sides of the drawer. The raised strips are slidably connected to the slide rails in the horizontal direction. The raised strips and slide rails make the drawer slide more smoothly and stably.

[0010] Preferably, the drawer is equipped with a clamping assembly that clamps the gas storage tank, which can prevent the gas storage tank from shaking during transportation, thereby avoiding noise or damage to the gas storage tank.

[0011] Preferably, the clamping assembly includes a first clamping plate, a second clamping plate, a base plate, and a screw. The first clamping plate and the base plate are both fixedly connected to the drawer. The second clamping plate is located between the first clamping plate and the base plate. The screw passes through the base plate and is threadedly connected to it. One end of the screw is rotatably connected to the second clamping plate. Rotating the screw allows it to move linearly along its own axis, thereby moving the second clamping plate away from or towards the first clamping plate. This allows for rapid adjustment of the distance between the first and second clamping plates, enabling quick disassembly and installation of the gas storage tank.

[0012] Preferably, the clamping assembly further includes a bearing, the outer ring of which is fixedly connected to the second clamping plate, and one end of the screw is fixedly connected to the inner ring of the bearing. It is understood that the bearing can reduce the resistance to the screw's rotation relative to the second clamping plate, allowing maintenance personnel to rotate the screw more easily.

[0013] Preferably, the first clamping plate has a first arc-shaped groove on the side near the second clamping plate, and the second clamping plate has a second arc-shaped groove on the side near the first clamping plate. The opposite sides of the gas storage tank are respectively fitted with the first arc-shaped groove and the second arc-shaped groove. The first and second arc-shaped grooves increase the contact area between the first and second clamping plates and the gas storage tank, thereby clamping the gas storage tank more securely.

[0014] Preferably, a smoke sensor is installed inside the storage cavity. The smoke sensor can detect whether there is smoke inside the storage cavity in real time. When smoke is detected, it indicates that there is a tendency for fire to start. The smoke sensor allows for timely detection of smoke, enabling prompt extinguishing of any flames and preventing the fire from spreading.

[0015] Preferably, the housing is provided with a gas delivery channel, and the gas storage tank is connected to the gas nozzle through the gas delivery channel. A solenoid valve is provided on the gas delivery channel or at the outlet end of the gas storage tank, and the solenoid valve is electrically connected to the smoke sensor. When the smoke sensor detects smoke, it sends a signal to the solenoid valve, causing the solenoid valve to open. Gas from the gas storage tank is then immediately delivered through the gas delivery pipeline to the gas nozzle and ejected, thereby achieving automatic fire extinguishing without the need for manual intervention.

[0016] Preferably, the top of the enclosure is equipped with a shield, and a solar panel is mounted on top of the shield. A storage battery is housed inside the drawer, and the solar panel is electrically connected to the storage battery. The solenoid valve and the smoke sensor are also electrically connected to the storage battery. The shield can block rainwater, preventing large amounts of rainwater from entering the storage chamber. Since the enclosure is generally exposed to sunlight, the solar panel can convert sunlight into electrical energy and store it in the storage battery. The storage battery then powers the solenoid valve and smoke sensor, eliminating the need for an external power source, making it more environmentally friendly, and reducing operating costs.

[0017] Preferably, the system also includes a trash can, which is placed inside the storage cavity; a door is rotatably connected to one side of the housing; the smoke sensor and the gas nozzle are both located above the trash can. The trash can can be removed from the storage cavity by opening the door, and the door and trash can facilitate waste disposal.

[0018] The beneficial effects of this utility model are:

[0019] 1. The system features a drawer and a spring mechanism. The gas storage tank is placed inside the drawer, and maintenance personnel can immediately eject the drawer by opening the lock with a key. This makes the maintenance and replacement of the gas storage tank simpler and faster.

[0020] 2. The gas storage tank is clamped in the drawer by the clamping assembly. The distance between the second clamping plate and the first clamping plate can be adjusted by rotating the screw, thereby realizing the quick disassembly and installation of the gas storage tank.

[0021] 3. Install solar panels and batteries. The solar panels convert light energy into electrical energy and store it in the batteries. The batteries then power the electrical equipment, which is more environmentally friendly and can reduce operating costs. Attached Figure Description

[0031] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0032] Example 1

[0033] This embodiment is a first embodiment of an automatic fire-extinguishing trash can, combined with... Figures 1 to 5 As shown, it includes a gas storage tank 2 and a box 1 with a storage cavity 101. A gas nozzle 102 is provided on the inner wall of the storage cavity 101, and the outlet end of the gas storage tank 2 is connected to the gas nozzle 102. A storage groove 103 is provided on the back of the box 1. Further, it also includes a drawer box 3 and an elastic element 5. The drawer box 3 is located in the storage groove 103, and a box lock 4 is provided on the outside of the drawer box 3. A locking structure (not shown in the figure) that cooperates with the box lock 4 is provided on the storage groove 103. The drawer box 3 is locked in the storage groove 103 by the cooperation of the locking structure and the box lock 4 to prevent the drawer box 3 from opening. The gas storage tank 2 is located in the drawer box 3. The two ends of the elastic element 5 are respectively connected to the inner wall of the storage groove 103 and the inner side of the drawer box 3. It can be understood that the outer side of the drawer box 3 is the side exposed to the outside, and the inner side is the side opposite to the outer side. The back of the box 1 is on the same side as the outer side of the drawer box 3.

[0034] The locking structure can be a latch located at the bottom of the storage slot 103. The box lock 4 includes a pin and a linkage component. When the drawer 3 is pushed into the storage slot 103, the linkage component drives the pin to engage with the latch, thereby locking the drawer 3 within the storage slot 103. Alternatively, the box lock 4 can also be a screw lock or a push-rod lock, etc. The structure of the locking structure corresponds to the structure of the box lock 4. The box lock 4 can be opened or closed using a key. Both the box lock 4 and the locking structure are existing technologies; therefore, this embodiment will not provide a more detailed explanation of their structure and principles.

[0035] Specifically, there are two elastic elements 5, both of which are springs.

[0036] Furthermore, the storage slot 103 is provided with two limiting slots 108, and two elastic elements 5 are respectively installed in the two limiting slots 108.

[0037] Furthermore, slide rails 104 are provided on both the left and right sides of the storage slot 103, and protrusions 301 are provided on both the left and right sides of the drawer box 3. The protrusions 301 and slide rails 104 are slidably connected in the horizontal direction. The protrusions 301 and slide rails 104 can make the sliding of the drawer box 3 smoother and more stable.

[0038] The working principle or workflow of this embodiment is as follows: Under normal use, the drawer 3 is locked in the storage slot 103 by the drawer lock 4. When it is necessary to repair or replace the gas storage tank 2, the maintenance personnel only need to use the key to open the drawer lock 4 to release the connection between the drawer lock 4 and the locking structure. At this time, the drawer 3 will pop out of the storage slot 103 under the elastic force of the elastic element 5, and the maintenance personnel can quickly access the gas storage tank 2 to repair or replace it.

[0039] The beneficial effects of this embodiment are: by setting up a drawer and an elastic element, the gas storage tank is placed in the drawer. After the maintenance personnel use a key to open the lock, the elastic element can immediately pop out the drawer, making the maintenance and replacement of the gas storage tank simpler and faster.

[0040] Example 2

[0041] This embodiment is a second embodiment of an automatic fire-extinguishing trash can. This embodiment is similar to embodiment 1, except that, as shown in the example... Figure 5 and Figure 6 As shown, the drawer 3 is equipped with a clamping component that clamps the gas storage tank 2. This prevents the gas storage tank 2 from shaking during transportation, thereby avoiding noise or damage to the gas storage tank 2.

[0042] Furthermore, the clamping assembly includes a first clamping plate 6, a second clamping plate 7, a base plate 8, and a screw 9. The first clamping plate 6 and the base plate 8 are both fixedly connected to the drawer 3. The second clamping plate 7 is located between the first clamping plate 6 and the base plate 8. The screw 9 passes through the base plate 8 and is threadedly connected to it. One end of the screw 9 is rotatably connected to the second clamping plate 7. Rotating the screw 9 allows it to move linearly along its own axis, thereby moving the second clamping plate 7 away from or towards the first clamping plate 6. This allows for rapid adjustment of the distance between the first clamping plate 6 and the second clamping plate 7, enabling the rapid disassembly and installation of the gas storage tank 2.

[0043] Furthermore, the clamping assembly also includes a bearing 10, the outer ring of which is fixedly connected to the second clamping plate 7, and one end of the screw 9 is fixedly connected to the inner ring of the bearing 10. Understandably, the bearing 10 reduces the resistance to rotation of the screw 9 relative to the second clamping plate 7, allowing maintenance personnel to rotate the screw 9 more easily.

[0044] Furthermore, the first clamping plate 6 has a first arc-shaped groove 601 on the side near the second clamping plate 7, and the second clamping plate 7 has a second arc-shaped groove 701 on the side near the first clamping plate 6. The opposite sides of the gas storage tank 2 are respectively fitted with the first arc-shaped groove 601 and the second arc-shaped groove 701. The first arc-shaped groove 601 and the second arc-shaped groove 701 can increase the contact area between the first clamping plate 6 and the second clamping plate 7 and the gas storage tank 2, thereby clamping the gas storage tank 2 more securely.

[0045] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 1.

[0046] Example 3

[0047] This embodiment is a third embodiment of an automatic fire-extinguishing trash can. This embodiment is similar to embodiment 2, except that it combines... Figures 1 to 5 As shown, a smoke sensor 11 is installed inside the storage cavity 101. The smoke sensor 11 can detect whether there is smoke inside the storage cavity 101 in real time. When smoke is detected, it indicates that there is a fire tendency inside the storage cavity 101. The smoke sensor 11 can detect smoke in time so that the flames can be extinguished in time and the fire can be prevented from spreading.

[0048] Furthermore, a controller 14 is installed inside the drawer 3; a gas supply channel 106 is provided on the housing 1, and a solenoid valve 12 is installed at the outlet end of the gas storage tank 2. The solenoid valve 12 and the smoke sensor 11 are both electrically connected to the controller 14. The solenoid valve 12 is connected to a connecting pipe 13, one end of which is connected to the gas supply channel 106. When the smoke sensor 11 detects smoke, it sends a signal to the controller 14, which then controls the solenoid valve 12 to open. The gas in the gas storage tank 2 immediately enters the gas supply pipeline through the connecting pipe 13 and is finally sprayed out from the gas nozzle 102, thereby realizing the automatic fire extinguishing function without the need for manual fire extinguishing operation.

[0049] Furthermore, the top of the housing 1 is equipped with a shield 107, and a solar panel 15 is mounted on top of the shield 107. A storage battery 16 is housed inside the drawer 3, and the solar panel 15 is electrically connected to the storage battery 16. The solenoid valve 12 and the smoke sensor 11 are also electrically connected to the storage battery 16. The shield 107 can block rainwater, preventing large amounts of rainwater from entering the storage chamber 101. Since the housing 1 is generally exposed to sunlight, the solar panel 15 can convert light energy into electrical energy and store it in the storage battery 16. The storage battery 16 then powers the solenoid valve 12 and the smoke sensor 11, eliminating the need for an external power source, making it more environmentally friendly, and reducing operating costs.

[0050] Furthermore, it also includes a trash can 17, which is placed inside the storage cavity 101; a door 105 is rotatably connected to one side of the container 1; a smoke sensor 11 and a gas nozzle 102 are both located above the trash can 17. The trash can 17 can be removed from the storage cavity 101 by opening the door 105. The door 105 and the trash can 17 facilitate the disposal of garbage.

[0051] Other features, working principles, and beneficial effects of this embodiment are the same as those of Embodiment 2.

[0052] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description, and it is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
