Description

TECHNICAL FIELD

[0001] The present application relates to the field of garbage disposal, in particular to a garbage can door failure monitoring device. BACKGROUND

[0002] The garbage cans widely used in the current market are usually composed of a shell and a barrel, and the shell is provided with an inlet and outlet and a throwing opening for placing the barrel and throwing garbage respectively. When the barrel is placed into the shell from the inlet and outlet, the barrel is located below the throwing opening, so that the user can directly throw garbage into the barrel through the throwing opening. With the popularization of the concept of smart city and the progress of technology, intelligence has become an important trend of garbage can development. However, most of the existing intelligent garbage cans still lack effective state monitoring mechanism, especially when the door at the throwing opening cannot be opened due to too much garbage, if the garbage in the barrel is not cleaned in time, it will affect the normal garbage throwing.

[0003] The specific solution of the prior art: In order to solve this problem, some manufacturers take the method of increasing the capacity of the garbage can to reduce the possibility of garbage overflow, but this does not fundamentally solve the problem, but increases the cost. Another common solution is to install a monitoring device in the garbage can, and the maintenance personnel can check the garbage state in the barrel in time through monitoring in the background, but since the number of garbage cans monitored in the background is large, the monitoring difficulty is also large, the monitoring efficiency is low and it is easy to be ignored. CONTENT OF THE UTILITY MODEL

[0004] In order to realize the timely monitoring of the garbage in the garbage can, reduce the monitoring difficulty of the staff, and ensure the normal throwing of garbage, the present application provides a garbage can door failure monitoring device.

[0005] The garbage can door failure monitoring device provided by the present application adopts the following technical scheme:

[0006] A garbage can door failure monitoring device is installed on a garbage can, the garbage can includes a shell and a barrel installed in the shell, one side of the shell is provided with an inlet and outlet for placing the barrel into the shell, and an inlet and outlet door is hinged at the inlet and outlet; the side of the shell provided with the inlet and outlet is provided with a throwing opening, the throwing opening is located above the inlet and outlet, a throwing door is hinged at the throwing opening, and a driving assembly for driving the throwing door to rotate and open is arranged inside the shell; comprising:

[0007] A detection assembly is installed in the shell for detecting whether the garbage can fails;

[0008] A controller is connected with the detection assembly, receives the data / signal detected by the detection assembly, and outputs a reminding signal;

[0009] An alarm is connected to the controller and sends an alarm when receiving the reminder signal output by the controller.

[0010] By adopting the above technical solution, the detection assembly can detect whether the garbage can is malfunctioning, including but not limited to whether the garbage in the barrel exceeds the set value, whether the deposit door can be normally opened, and whether the access door has been closed in place, thereby accurately determining the working condition of the garbage can. After the controller receives the data / signal of the detection assembly, it can output the corresponding reminder signal to realize immediate response to the fault. After the alarm receives the reminder signal of the controller, it will send an alarm to remind the management personnel to handle the problem in a timely manner, avoid the situation that the deposit opening cannot be opened due to garbage overflow, and improve the efficiency and reliability of garbage management.

[0011] Optionally, the detection assembly includes a first detection member for detecting whether the garbage in the barrel is higher than the set value, a second detection member for detecting whether the deposit door can be normally opened, and a third detection member for detecting whether the access door is normally closed; the reminder signal includes a first signal for reminding whether the garbage in the barrel is higher than the set value, a second signal for reminding whether the deposit door is malfunctioning and cannot be opened, and a third signal for reminding whether the access door is not closed in place; the alarm includes a first alarm for receiving the first signal, a second alarm for receiving the second signal, and a third alarm for receiving the third signal.

[0012] By adopting the above technical solution, the first detection member is used to detect whether the garbage in the barrel exceeds the preset height threshold. When the garbage height reaches the set value, the controller will output the first signal, and the first alarm will immediately send an alarm after receiving the signal, reminding the management personnel to handle the garbage in a timely manner to avoid the deposit opening being unable to be normally used due to too much garbage. The second detection member is used to detect whether the deposit door can be normally opened. If the deposit door cannot be normally opened, the controller will output the second signal, and the second alarm will send an alarm after receiving the signal, prompting the management personnel that the deposit door is malfunctioning and needs to be repaired in a timely manner to ensure the smooth deposit of garbage. The third detection member is used to detect whether the access door is normally closed. If the access door cannot be correctly closed, the controller will output the third signal, and the third alarm will send an alarm after receiving the signal, reminding the management personnel to check the state of the access door to prevent garbage leakage or external foreign matter from entering the inside of the garbage can. Therefore, the device realizes comprehensive monitoring of the garbage amount in the garbage can, the state of the deposit door, and the state of the access door through multiple detection members and corresponding alarms, effectively improving the use safety and management efficiency of the garbage can.

[0013] Optionally, the first detection member comprises a first infrared emitter fixed on the inner wall of the shell and a first infrared receiver fixed on the inner wall of the shell, the first infrared emitter and the first infrared receiver are respectively located on opposite sides of the shell, the first infrared receiver can receive the signal emitted by the first infrared emitter, and outputs a full bin signal when the first infrared receiver cannot receive the signal emitted by the first infrared emitter; the controller outputs the first signal after receiving the full bin signal, and the first alarm is used for receiving the first signal and sounding an alarm when receiving the first signal.

[0014] By adopting the above technical scheme, the garbage bin door fault monitoring device can effectively detect whether the garbage in the garbage can exceeds the preset height. Specifically, the first infrared emitter and the first infrared receiver are respectively fixed on opposite sides of the shell, when the garbage in the garbage can blocks the infrared signal, the first infrared receiver cannot receive the signal emitted by the first infrared emitter, thereby outputting a full bin signal. The controller outputs the first signal after receiving the full bin signal, triggers the first alarm to sound an alarm, prompts the management personnel to handle the garbage in time, avoids the problem that the depositing door cannot be normally opened or is normally opened and is hindered by the garbage due to the overfull garbage, and improves the use reliability and management efficiency of the garbage can.

[0015] Optionally, the first detection member comprises a distance measuring sensor fixed on the inner wall of the top of the shell, the distance measuring sensor is used for detecting the distance between itself and the garbage, and transmitting the detected data to the controller in real time, and the controller outputs the first signal when the data detected by the distance measuring sensor received by the controller is less than a set value, and the first alarm is used for receiving the first signal and sounding an alarm when receiving the first signal.

[0016] By adopting the above technical scheme, the distance measuring sensor is fixed on the inner wall of the top of the shell, can detect the height of the garbage in real time, and transmit the data to the controller. When the height of the garbage exceeds the preset value, the controller generates the first signal to trigger the first alarm to sound an alarm, thereby timely reminding the management personnel to handle the garbage, avoiding the problem that the depositing door cannot be normally opened or is normally opened and is hindered by the garbage due to the overfull garbage, and improving the use reliability and management efficiency of the garbage can.

[0017] Optionally, a control switch is arranged on the outer wall of the shell, the control switch is connected with the controller, outputs an opening door signal after receiving an opening door instruction, the controller receives the opening door signal output by the control switch and outputs an action signal, and the driving assembly acts to control the depositing door to open after receiving the action signal.

[0018] By adopting the technical scheme, precise control of the garbage can drop door can be realized. Specifically, when the control switch receives the door opening instruction of the user, the controller can quickly respond and output an action signal, and the driving assembly can act immediately after receiving the signal, so that the drop door can be smoothly opened. This not only improves the user experience, but also ensures the smoothness and reliability of the garbage drop process. At the same time, the design of the control switch enables the user to open the drop door through simple operation, which is convenient and fast.

[0019] Optionally, the second detection member includes a proximity switch installed on one side of the drop port. When the drop door closes the drop port, the drop door is located in the detection range of the proximity switch. When the drop door opens the drop port, the drop door moves away from the detection range of the proximity switch, and the proximity switch cannot detect the drop door.

[0020] By adopting the above technical scheme, when the drop door closes the drop port, the drop door is located in the detection range of the proximity switch, ensuring that the system can accurately determine the state of the drop door. When the drop door opens the drop port, the drop door moves away from the detection range of the proximity switch, and the proximity switch cannot detect the drop door, thereby triggering the subsequent fault detection logic, effectively improving the accuracy of the garbage can door fault monitoring, reducing the misjudgment rate, and ensuring the normal drop of garbage.

[0021] Optionally, the controller is internally provided with a timer. When the controller outputs the action signal, the timer starts timing. When the proximity switch always detects the drop door after timing for a set time, the controller outputs the second signal, and the second alarm is used to receive the second signal and issue an alarm when the second signal is received.

[0022] By adopting the above technical scheme, accurate detection and timely alarm of the drop door fault are realized. Specifically, the timer internally provided in the controller can output the second signal to trigger the second alarm to issue an alarm when the drop door fails to complete the opening action within a predetermined time, thereby effectively avoiding the problem of blocked garbage drop caused by the drop door fault, and improving the working reliability of the garbage can. At the same time, this scheme also reduces the frequency of manual inspection and reduces the maintenance cost.

[0023] Optionally, the control switch is an inductive switch installed on the shell and / or a press switch installed on the shell.

[0024] By adopting the above technical scheme, the opening function of the drop door is realized in a non-contact and / or manual triggering manner, which improves the convenience and hygiene of operation, and reduces the risk of misoperation.

[0025] Optionally, the third detection member comprises a contact switch mounted on the side wall of the inlet and outlet, and the access door abuts against the contact switch when the access door is buckled on the inlet and outlet.

[0026] By adopting the above technical scheme, the garbage bin door fault monitoring device can timely issue an alarm when the access door is not properly closed, thereby avoiding problems such as garbage scattering or odor spreading caused by the access door not being properly closed, and improving the use safety and environmental hygiene level of the garbage bin. Specifically, when the access door is buckled on the inlet and outlet, the access door abuts against the contact switch, and at this time, the contact switch is in a closed state, and the controller does not output an alarm signal. If the access door is not properly closed or is accidentally opened, the contact switch will be disconnected, the controller will output a third signal after receiving the signal, and the third alarm will issue an alarm to remind the staff to handle it in time.

[0027] Optionally, the third detection member is connected with the controller, and the controller is internally provided with a timer. When the third detection member detects that the access door is opened, it outputs an opening signal. After the controller receives the opening signal, it controls the timer to start timing. When the timer timing reaches a set value and the third detection member does not detect that the access door is closed, the controller outputs the third signal, and the third alarm issues an alarm after receiving the third signal.

[0028] By adopting the above technical scheme, effective monitoring of the state of the garbage bin access door is realized. Specifically, the third detection member can detect the opening state of the access door and send an opening signal to the controller after opening. After receiving the signal, the controller starts the internal timer to begin timing. If the access door is still not closed within the set time, the controller will output a third signal to trigger the third alarm to issue an alarm. This design ensures that in the case of long-term non-closure of the access door, the staff can be reminded in time, thereby avoiding problems such as garbage scattering caused by the access door not being closed, and improving the safety and use reliability of the garbage bin.

[0029] In summary, the present application has the following at least one beneficial technical effect:

[0030] 1. By cooperation of the detection assembly, the controller and the alarm, the fault state of the garbage bin can be monitored in real time, the access door can issue an alarm in time when the garbage is excessive, the normal opening of the access door can be ensured when the garbage is full, and the reliability of garbage disposal is improved.

[0031] 2. The first detection member in the detection assembly can detect whether the garbage in the barrel body exceeds the set value, the controller outputs a reminder signal after receiving the relevant signal, and the management personnel can take measures quickly to prevent the garbage from overflowing, thereby reducing the work intensity of manual inspection.

[0032] 3. The second detection member and the third detection member detect the state of the drop door and the access door respectively, when it is detected that the drop door cannot be normally opened or the access door is not closed in place, the controller outputs the corresponding prompt signal, and the alarm gives an alarm, ensuring the normal operation of each part of the garbage can, and improving the stability and safety of the overall system.

DETAILED DESCRIPTION

[0038] The following will be combined with the Figures 1-4 The present application is further described in detail.

[0039] The embodiments of the present application disclose a garbage can door fault monitoring device. The garbage can door fault monitoring device is installed on the garbage can, referring to Figure 1 and Figure 2The garbage can comprises a shell 1 and a barrel 2 installed in the shell 1, an inlet and outlet 11 is formed on one side of the shell 1 for the barrel 2 to be put into the shell 1, and an access door 12 is hinged at the inlet and outlet 11; meanwhile, a throwing opening 13 is formed on the side of the shell 1 where the inlet and outlet 11 is formed, the throwing opening 13 is located on the upper side of the inlet and outlet 11, a throwing door 14 is hinged at the throwing opening 13, and a driving assembly 15 for driving the throwing door 14 to rotate and open is arranged in the shell 1. The driving assembly 15 can be a pneumatic cylinder, an electric push rod or the like, the throwing door 14 can be driven by the driving assembly 15 to rotate inwardly around the hinge shaft of the shell 1 to open the throwing opening 13, so that the staff can throw the garbage into the barrel 2 in the shell 1 through the throwing opening 13. However, when the garbage in the barrel 2 is too high, the throwing door 14 abuts against the garbage when the throwing door 14 is rotated by the driving assembly 15, which will affect the normal opening of the throwing door 14, and if the garbage in the barrel 2 is not cleaned in time, the garbage throwing work will be affected.

[0040] Referring to Figure 2 and Figure 3 The garbage can door fault monitoring device comprises a detection assembly 3 installed in the shell 1 for detecting whether the garbage in the barrel 2 is higher than a set position, an alarm 5 arranged in the background for reminding the staff whether the access door 12 and the throwing door 14 are abnormal, and a controller 4 connected between the detection assembly 3 and the alarm 5, the controller 4 can receive the data / signal detected by the detection assembly 3 and output a reminding signal, and the alarm 5 can receive the reminding signal output by the controller 4 and alarm when the reminding signal is received. The alarm 5 is installed in the background, so that the staff can monitor the state of each garbage can in time, and the staff can be reminded in time when the garbage can has a problem, thereby reducing the monitoring difficulty of the staff.

[0041] The detection assembly 3 comprises a first detection piece 31 for detecting whether the garbage in the barrel 2 is higher than a set value, a second detection piece 32 for detecting whether the throwing door 14 can be normally opened, and a third detection piece 33 for detecting whether the access door 12 is normally closed. The reminding signal comprises a first signal for reminding whether the garbage in the barrel 2 is higher than a set value, a second signal for reminding whether the throwing door 14 is faulty and cannot be opened, and a third signal for reminding whether the access door 12 is not closed in place. The alarm 5 comprises a first alarm 51 for receiving the first signal, a second alarm 52 for receiving the second signal, and a third alarm 53 for receiving the third signal.

[0042] Referring to Figure 2Specifically, the first detection member 31 comprises a first infrared emitter 311 fixed on the inner wall of the shell 1 for detecting the height of the garbage in the barrel 2 and a first infrared receiver 312 fixed on the inner wall of the shell 1 for receiving the signal emitted by the first infrared emitter 311. The first infrared emitter 311 and the first infrared receiver 312 are respectively located on the opposite sides of the barrel 2, so that the first infrared receiver 312 can normally receive the signal emitted by the first infrared emitter 311. When the height of the garbage in the barrel 2 is higher than the set value, the garbage will block the signal emitted by the first infrared emitter 311 to the first infrared receiver 312, and the controller 4 will also receive the information that the first infrared receiver 312 cannot receive the signal of the first infrared emitter 311. At this time, the controller 4 outputs the first signal, and the first alarm 5 emits an alarm after receiving the first signal to remind the staff that the garbage in the barrel 2 is too much.

[0043] Of course, the first detection member 31 for detecting the height of the garbage in the barrel 2 can also be a distance measuring sensor 313 installed on the inner wall of the top of the shell. The distance measuring sensor 313 can detect the height between itself and the garbage in the barrel 2 in real time and transmit the detected data to the controller 4 in real time. When the controller 4 receives the data transmitted by the detection assembly 3 below the set value, it means that the distance between the garbage and the distance measuring sensor 313 is small, and the height of the garbage is too high. At this time, the controller 4 outputs the above-mentioned first signal, and the first alarm 5 emits an alarm after receiving the first signal to realize the detection of the height of the garbage in the barrel 2.

[0044] Referring to Figure 1 and Figure 2 A control switch 6 for controlling the opening of the throwing door 14 is arranged on the outer wall of the shell 1. The control switch 6 is connected with the driving assembly 15 through the controller 4. When it is needed to open the throwing door 14, the control switch 6 will receive an opening instruction. When the control switch 6 receives the opening instruction, it outputs an opening signal. When the controller 4 receives the opening signal, it outputs an action signal. After the driving assembly 15 receives the action signal, it acts to control the opening of the throwing door 14.

[0045] Among them, the control switch 6 can be an induction switch 61 installed on the shell 1 and / or a press switch 62 installed on the shell 1. When the user needs to open the throwing door 14 to throw garbage into the barrel 2, the throwing door 14 can be directly opened through the induction switch 61 or the press switch 62.

[0046] Referring to Figure 2The second detection member 32 is arranged at the throwing opening 13 and is used to detect whether the throwing door 14 can be normally opened. When the user opens the throwing door 14 through the control switch 6, the throwing door 14 cannot be normally opened due to the failure of the driving assembly 15, and the staff cannot obtain the information of the failure of the driving assembly 15 in time, so that the situation that the driving assembly 15 cannot be repaired in time is avoided.

[0047] The second detection member 32 comprises a proximity switch 321 arranged at one side of the throwing opening 13. When the throwing door 14 is in the closed state, the proximity switch 321 can detect. When the throwing door 14 is in the opened state, the throwing door 14 is moved away from the proximity switch 321, so that the proximity switch 321 cannot detect the throwing door 14. The proximity switch 321 is connected with the controller 4, and a timer is arranged in the controller 4. When the controller 4 outputs the action signal, the timer in the controller 4 also starts timing. If the timer reaches the set time, the proximity switch 321 detects that the throwing door 14 has not been opened, which indicates that the throwing door 14 fails to open. At this time, the controller 4 outputs the second signal, and the second alarm 52 emits an alarm after receiving the second signal.

[0048] With reference to Figure 4 The third detection member 33 is arranged at the inlet and outlet 11 and is used to detect whether the access door 12 at the inlet and outlet 11 is normally closed. The situation that the access door 12 cannot be normally closed due to that the cylinder 2 is not placed in place in the shell 1 is avoided.

[0049] The third detection member 33 comprises a contact switch 331 fixed at one side of the shell 1. The contact switch 331 can be a travel switch. When the access door 12 blocks the inlet and outlet 11, the access door 12 abuts against the travel switch. The travel switch is connected with the controller 4. When the travel switch detects that the access door 12 is out of the abutting relationship with the travel switch, the travel switch outputs the door opening signal, and the controller 4 receives the door opening signal to control the internal timer to time. When the timer reaches the set value, the travel switch detects that the access door 12 is not closed, the controller 4 outputs the third signal, and the third alarm 5 emits an alarm after receiving the third signal. It can be detected whether the access door 12 is in the closed state. If the access door 12 is not closed for a long time, it is possible that the cylinder 2 in the shell 1 is not placed in place and hinders the closing of the access door 12. Therefore, the third alarm 5 emits an alarm to remind the staff to place the cylinder 2 in place in time, so that the garbage thrown from the throwing opening 13 does not reach the gap between the cylinder 2 and the inner wall of the shell 1, and the normal throwing work of the garbage is affected.

[0050] The implementation principle of the garbage can door fault monitoring device is as follows: during use, the controller 4 and the alarm 5 are installed at the back for monitoring and management by the staff; when the garbage in the barrel 2 is too much, the first detection member 31 will detect and output a full bin signal; when the receiver receives the full bin signal, a first signal is output; after the first alarm 51 receives the first signal, an alarm is sounded. When the drive assembly 15 fails to normally drive the opening of the drop door 14, the second detection member 32 will detect, the controller 4 will output a second signal, and after the second alarm 52 receives the second signal, an alarm is sounded. After the staff clean the garbage in the barrel 2 and then place the barrel 2 into the shell 1 again, if the barrel 2 is not placed in place or the access door 12 is not closed in place, the third detection member 33 will detect, at this time, the controller 4 will output a third signal, and after the third alarm 5 receives the third signal, an alarm is sounded. The staff can hear the alarm sound to know that the garbage can has a fault, active reminding of the staff is realized, and according to which alarm sounds, the type of fault of the garbage can can be determined. It can be understood that a display screen can also be provided, which is connected with the controller 4 and is used for displaying the number of the garbage can with the fault, so that the staff can be directly reminded of which position of the garbage can has what kind of fault.

[0051] The controller 4 can be a PLC controller 4 or a single-sided machine, as long as it can realize the basic functions of signal transmission and comparison.

[0052] The above are preferred embodiments of the application, and do not limit the protection scope of the application, so that: any equivalent changes made according to the structure, shape, principle of the application should be covered within the protection scope of the application.
