[0046] In the following, the application will be further described in combination with specific embodiments, and it should be noted that the following described embodiments or technical features can be combined to form new embodiments without conflict.

[0047] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0048] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0049] One aspect of this application provides a bag-laying detection system, such as Figures 1 to 5 As shown, in one preferred embodiment, there are at least one detection component 200 and a controller 300 disposed in the upper part of the inner cavity of the bin 100. The detection component 200 can detect the garbage bag 500 during the laying process. The controller 300 is installed in the bin 100 and electrically connected to the detection component 200. The controller 300 can receive the trigger signal from the detection component 200 during the bag laying process, and thus determine whether the laying of the garbage bag 500 meets the usage requirements based on the trigger state of the detection component 200. If the laid garbage bag 500 does not meet the usage requirements, the controller 300 can issue an alarm.

[0050] Understandably, the requirements for laying garbage bags 500 are: the lower part of the garbage bag 500 needs to be close to or in contact with the bottom of the inner cavity of the bin 100, and the upper part of the garbage bag 500 needs to meet the subsequent sealing requirements. Furthermore, the less garbage bag 500 remains during laying, the easier it is for it to be absorbed by the air inlet device located at the bottom of the inner cavity of the bin 100. Therefore, under normal circumstances, when the garbage bag 500 is laid, the bottom of the garbage bag 500 is in direct contact with the bottom of the inner cavity of the bin 100. Thus, by installing at least one detection component 200 in the upper part of the inner cavity of the bin 100 to detect the upper part of the garbage bag 500, it can be determined whether the upper part of the remaining garbage bag 500 can meet the sealing requirements during the final laying.

[0051] It is also understandable that the number of detection components 200 in the upper part of the inner cavity of the barrel 100 can be set according to actual needs. The more components there are and the more they are distributed along the circumference, the higher the detection accuracy, but the corresponding cost will also increase. In this application, it is preferable to set one detection component 200 in the upper part of the inner cavity of the barrel 100.

[0052] In this embodiment, as shown in Figures 1 to 3 The distance between the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 and the upper port of the barrel 100 is 0%-10% of the total depth of the barrel 100.

[0053] It can be understood that the closer the distance between the detection assembly 200 and the upper port of the barrel 100, the higher the detection accuracy. However, it is not convenient to install the detection assembly 200 if the distance between the detection assembly 200 and the upper port of the barrel 100 is too close. Meanwhile, when the remaining length of the garbage bag 500 cannot meet the packaging length, the garbage bag 500 can be separated from the laying mechanism under the adsorption of the air inlet device. At this time, the garbage bag 500 falls and stacks under the action of gravity or adsorption force, thereby causing a certain distance between the upper end position of the garbage bag 500 and the upper port position of the barrel 100, which can generally reach 20%-30% of the total depth of the barrel 100. That is, the farthest distance between the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 and the upper port of the barrel 100 can be 30% of the total depth of the barrel 100. However, in order to ensure that the detection assembly 200 has sufficient detection accuracy, the maximum distance between the installation position of the detection assembly 200 and the upper port of the barrel 100 is preferably 10% of the total depth of the barrel 100.

[0054] In one embodiment of the present application, as shown in Figures 1 to 5 The number of detection assemblies 200 is at least one pair. At least one detection assembly 200 is arranged at the upper part of the inner cavity of the barrel 100, and at least one detection assembly 200 is arranged at the lower part of the inner cavity of the barrel 100. The controller 300 can determine whether the laying of the garbage bag 500 meets the use requirements by receiving the triggering state of the detection assemblies 200 at the upper and lower parts of the inner cavity of the barrel 100.

[0055] It can be understood that the existing part of the laying mechanism also has a fixed function, that is, one end of the garbage bag 500 is fixedly connected with the laying mechanism. When the remaining length of the garbage bag 500 cannot meet the laying length, the lower end of the garbage bag 500 is located in the barrel 100 under the adsorption of the air inlet device, and the upper end of the garbage bag 500 can be connected with the laying mechanism. Therefore, when the controller 300 determines whether the laying of the garbage bag 500 meets the use requirements, the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 can be used to detect whether the laid garbage bag 500 meets the sealing requirement, and the detection assembly 200 located at the lower part of the inner cavity of the barrel 100 can be used to detect whether the laid garbage bag 500 is close to or contacts the bottom of the inner cavity of the barrel 100. Therefore, at least two detection assemblies 200 can be used to realize double detection of the garbage bag 500, which can effectively improve the detection effect of the laying process of the garbage bag 500 compared with the traditional single detection, thereby improving the user experience.

[0056] In this embodiment, the detection mode of the detection assembly 200 can be divided into several types according to the working principle, including but not limited to the following three types.

[0057] Mode one: the detection assembly 200 is a light detection assembly; in the process of laying the garbage bag 500, the light detection assembly is triggered by the shielding of light by the garbage bag 500, and then the position of the garbage bag 500 in the laying process is obtained.

[0058] It can be understood that the light detection assembly can be selected from an infrared sensor or other devices with similar functions. Taking the infrared sensor as an example, it can continuously emit infrared light to the laying path of the garbage bag 500 when working. Thus, during the laying process of the garbage bag 500, the garbage bag 500 will interfere with the infrared light; and then the light detection assembly is triggered by the interference of the infrared light to obtain the laying position of the garbage bag 500.

[0059] Mode two: the detection assembly 200 is a visual detection assembly; in the process of laying the garbage bag 500, the visual detection assembly is triggered by recognizing the garbage bag 500, and then the position of the garbage bag 500 in the laying process is obtained.

[0060] It can be understood that the visual detection assembly can be selected from a visual sensor or other devices with similar functions. When working, it continuously monitors images or videos of the laying path of the garbage bag 500. When the garbage bag 500 passes, the visual detection assembly captures the image of the garbage bag 500, so as to recognize and obtain the laying position of the garbage bag 500.

[0061] Mode three: the detection assembly 200 is a pressure detection assembly; in the process of laying the garbage bag 500, the pressure detection assembly is triggered by the pressure generated by the garbage bag 500, and then the position of the garbage bag 500 in the laying process is obtained.

[0062] It can be understood that the pressure detection assembly can be selected from a pressure sensor or other devices with similar functions. In the process of laying the garbage bag 500, the bottom of the barrel 100 will generate a downward adsorption force on the garbage bag 500 through the installed air inlet device to assist the laying, so that when the garbage bag 500 is laid, the garbage bag 500 will generate pressure on the bottom of the barrel 100 or the bottom and the inner wall, and then trigger the pressure detection assembly to determine whether the garbage bag 500 is laid.

[0063] At the same time, according to the different detection modes of the detection assembly 200, the installation positions of the detection assembly 200 are also different. For example Figure 1 , Figure 2 and Figure 4As shown, the detection components 200 are all disposed on the inner wall of the barrel 100; at this time, the detection components 200 can all be light detection components or all be vision detection components, or they can partially use light detection components and partially use vision detection components. For example Figure 3 As shown, the detection component 200 located in the upper part of the inner cavity of the barrel 100 is disposed on the inner wall of the barrel 100, and the detection component 200 located in the lower part of the inner cavity of the barrel 100 is disposed at the bottom end of the barrel 100. At this time, the detection component 200 located on the upper inner wall of the barrel 100 can be a light detection component or a vision detection component, while the detection component 200 located at the bottom end of the barrel 100 can be any one of a pressure detection component, a vision detection component, and a light detection component.

[0064] Specifically, such as Figure 2 As shown, when all detection components 200 are set on the inner wall of the barrel 100, and the detection component 200 located on the lower inner wall of the barrel 100 is a light detection component; the distance between the detection component 200 located on the lower inner wall of the barrel 100 and the bottom of the barrel 100 is H, and the value of H is 0%-10% of the total depth L of the barrel 100.

[0065] It is understandable that, due to the wrinkles that occur during the laying of the garbage bag 500 and its inherent elasticity, a certain gap between the bottom of the garbage bag 500 and the bottom of the bin 100 is sufficient to meet the usage requirements. However, the gap should not be too large; the specific distance can be determined through actual testing, and generally should not exceed 10% of the total depth of the bin 100. Therefore, to ensure that garbage bags 500 laid within the set gap are deemed to meet usage requirements, the detection components 200 located on the lower inner wall of the bin 100 need to be spaced out.

[0066] Specifically, such as Figure 4 As shown, when all detection components 200 are set on the inner wall of the barrel 100, and the detection component 200 located on the lower inner wall of the barrel 100 is a vision detection component; the distance between the detection component 200 located on the lower inner wall of the barrel 100 and the bottom of the barrel 100 is H, and the value of H is 0%-30% of the total depth L of the barrel 100.

[0067] Understandably, compared to the linear detection of the light-based detection component, the vision detection component performs range detection. Therefore, to improve the detection range of the vision detection component, a distance can be set between the vision detection component and the bottom of the barrel 100. The specific distance can be selected according to the type or structure of the vision detection component, and generally should not exceed 30% of the total depth of the barrel 100.

[0068] In the embodiment, as shown in Figure 1 , Figure 2 and Figure 4 , the detection assemblies 200 are arranged on the inner wall of the barrel 100. At least one side of the inner wall of the barrel 100 is provided with a detachable mounting plate 110, and the detection assemblies 200 are arranged on the mounting plate 110, so that the mounting and dismounting of the detection assemblies 200 can be facilitated through the detachable mounting plate 110. When the detection assemblies 200 located at the lower part of the inner cavity of the barrel 100 are arranged at the bottom end of the barrel 100, as shown in Figure 1 and Figure 3 , at least one side of the inner wall of the barrel 100 is provided with a detachable mounting plate 110, and the bottom of the inner cavity of the barrel 100 is provided with a detachable partition plate 120. The detection assemblies 200 located at the upper part of the inner cavity of the barrel 100 are detachably mounted on the mounting plate 110, and the detection assemblies 200 located at the lower part of the inner cavity of the barrel 100 are detachably mounted on the partition plate 120, so that the mounting and dismounting of the detection assemblies 200 can be facilitated.

[0069] It can be understood that if the detection assemblies 200 are directly mounted on the barrel 100, the barrel 100 needs to be formed with a mounting seat for mounting the detection assemblies 200 when being injection molded, which will increase the molding difficulty of the barrel 100, and it is also inconvenient to directly mount the detection assemblies 200 on the barrel 100. The mounting plate 110 and the partition plate 120 are only detachably mounted on the barrel 100 through screws, which will not increase the molding difficulty of the barrel 100. In addition, the mounting plate 110 and the partition plate 120 have a large size, which can facilitate the mounting, so that when the detection assemblies 200 are mounted, the detection assemblies 200 can be first mounted on the mounting plate 110 and the partition plate 120, and then mounted in the barrel 100 together.

[0070] In the embodiment, as shown in Figure 5 , the bag laying detection system further comprises an alarm 400, which is mounted in the barrel 100 and electrically connected with the controller 300. When the laying of the garbage bag 500 does not meet the use requirements, the controller 300 can control the alarm 400 to issue an alarm prompt.

[0071] It can be understood that there are various types of alarms 400, such as light flashing alarms and buzzer alarms, which can be used alone or in combination.

[0072] Another aspect of the present application provides a working method of the bag laying detection system, as shown in Figure 6 and Figure 7 , and a preferred embodiment thereof comprises the following working steps:

[0073] S100: The controller 300 can first detect the inner cavity of the barrel 100 by the detection assembly 200 to determine whether the inner cavity of the barrel 100 meets the bag laying condition. If the inner cavity of the barrel 100 meets the bag laying condition, the following steps are performed; if the inner cavity of the barrel 100 does not meet the bag laying condition, the controller 300 can control the alarm 400 to alarm.

[0074] S300: The controller 300 controls the bag laying mechanism to start laying the bag, and controls the detection assembly 200 to detect the laying process of the garbage bag 500 during the laying process of the garbage bag 500.

[0075] S400: The controller 300 can determine whether the laid garbage bag 500 meets the use requirement according to the triggering state of the detection assembly 200; if the laid garbage bag 500 meets the use requirement, the bag laying is completed; if the laid garbage bag 500 does not meet the use requirement, an alarm is prompted.

[0076] It can be understood that the packing, sealing and laying processes of the garbage bag 500 are sequentially performed. Therefore, before the laying process is performed, the inner cavity of the barrel 100 needs to be self-detected to ensure that the garbage bag 500 after packing and sealing has been cleaned.

[0077] Specifically, step S100 includes the following specific steps:

[0078] S110: The controller 300 can control the detection assembly 200 located in the inner cavity of the barrel 100 to detect the inner cavity of the barrel 100.

[0079] S120: If the detection assembly 200 is triggered, it means that there is an untreated garbage bag 500 in the inner cavity of the barrel 100; therefore, the controller 300 determines that the inner cavity of the barrel 100 does not meet the laying condition of the garbage bag 500 at this time, and controls the alarm 400 to issue an alarm prompt.

[0080] S130: If the detection assembly 200 is not triggered, it means that the inner cavity of the barrel 100 is empty; therefore, the controller 300 determines that the inner cavity of the barrel 100 meets the laying condition of the garbage bag 500 at this time, and controls the bag laying mechanism to perform the bag laying process in step S200.

[0081] Specifically, in step S110; if the inner cavity of the barrel 100 is only provided with the detection assembly 200 at the upper part, the controller 300 can only control the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 to detect the inner cavity of the barrel 100. If the inner cavity of the barrel 100 is provided with the detection assembly 200 at the upper part and the lower part, the controller 300 can control the detection assembly 200 located at the lower part of the inner cavity of the barrel 100 to detect the inner cavity of the barrel 100.

[0082] It can be understood that after the garbage bag 500 is packed and sealed, the sealed garbage bag 500 is separated from the garbage bag 500 on the laying mechanism, and the separation position is located at the upper part of the inner cavity of the barrel 100. Therefore, when performing self-checking of the barrel 100, if the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 is used, the inner cavity of the barrel 100 may exist a sealed garbage bag 500, but the upper end of the garbage bag 500 is lower than the detection assembly 200 located at the upper part of the inner cavity of the barrel 100; and then the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 is not triggered, which leads to a false judgment. Therefore, by selecting the detection assembly 200 located at the lower part of the inner cavity of the barrel 100 for self-checking, the above false judgment can be avoided.

[0083] In this embodiment, when only the upper part of the inner cavity of the barrel is provided with the detection assembly, the specific content of step S300 is: if the detection assembly is not triggered, the controller judges that the laying of the garbage bag does not meet the use requirement, and issues an alarm prompt; otherwise, the controller judges that the laying of the garbage bag meets the use requirement.

[0084] It can be understood that the above logical working process is applicable to the case that the laying mechanism has no fixed function.

[0085] In this embodiment, as shown in Figure 7 When the upper part and the lower part of the inner cavity of the barrel are provided with the detection assembly, step S300 includes the following specific steps:

[0086] S310: During the laying process of the garbage bag 500, if the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 is not triggered, the controller 300 can judge that the laying of the garbage bag 500 does not meet the use requirement, and control the alarm 400 to issue an alarm prompt; otherwise, the next step is performed.

[0087] S320: If the detection assembly 200 located at the lower part of the inner cavity of the barrel 100 is triggered, the controller 300 judges that the laying of the garbage bag 500 meets the use requirement; otherwise, it is judged that the laying of the garbage bag 500 does not meet the use requirement, and the alarm 400 is controlled to issue an alarm prompt.

[0088] It can be understood that, for convenience of description, the detection assembly 200 located at the upper part of the inner cavity of the barrel 100 can be set as a first detection assembly, and the detection assembly 200 located at the lower part of the inner cavity of the barrel 100 can be set as a second detection assembly. There are four cases of triggering of the first detection assembly and the second detection assembly during the laying process of the garbage bag 500.

[0089] (1) If neither the first detection assembly nor the second detection assembly is triggered, it indicates that there is no remaining garbage bag 500 on the laying mechanism or the laying mechanism has a fault. At this time, the controller 3 can control the alarm 400 to alarm to remind the user to add a new garbage bag 500 or contact the after-sales service for maintenance in time.

[0090] (2) If the first detection assembly is triggered and the second detection assembly is not triggered, it indicates that either the laying mechanism has a fault or the length of the remaining garbage bag 500 on the laying mechanism cannot meet the laying length requirement. At this time, the controller 3 can control the alarm 400 to alarm to remind the user to add a new garbage bag 500 or contact the after-sales service for maintenance in time.
