[0037] To better understand the above technical solutions, the following will describe the above technical solutions in detail with reference to specific implementation methods. It should be understood that the embodiments of this disclosure and the specific features in the embodiments are detailed descriptions of the technical solutions of this application, rather than limitations on the technical solutions of this application. In the absence of conflict, the embodiments of this application and the technical features in the embodiments can be combined with each other.

[0038] Referring to Figure 1, the intelligent waste adsorption device described in this embodiment is used to adsorb and recycle dust or micro-waste (such as hair) and micro-debris (such as paper scraps). The intelligent waste adsorption device includes a hollow housing 3 and a top cover 4 covering the upper part of the housing 3. The housing 3 and the top cover 4 are assembled into a complete outer shell to provide physical support and protection for the internal components. A receiving cavity 10 is provided in the middle of the housing 3, and a storage box 1 is inserted into the receiving cavity 10. A PCB assembly 6 is provided at the upper end, and a vacuum device 2 and an external air duct 8 are respectively connected to the lower end of the receiving cavity 10. The lower end of the external air duct 8 is connected to the suction port 11 at the bottom of the box 3, and the upper end of the external air duct 8 is connected to the storage box 1. A function selection module 5 is provided on the upper cover 4, a switch assembly 7 is provided on the box 3, and a sensing device 9 is provided on the side of the suction port 11. The function selection module 5, the switch assembly 7, the sensing device 9, and the vacuum device 2 are all electrically connected to the PCB assembly 6.

[0039] Referring to Figures 2-4, in this embodiment of the application, the storage box 1 has a hollow structure for storing the absorbed garbage. The bottom of the storage box 1 is provided with a snap-fit ​​18, and the bottom of the receiving cavity 10 is provided with a slot 20 corresponding to the position of the snap-fit ​​18. When the storage box 1 is inserted into the receiving cavity 10, the snap-fit ​​18 and the slot 20 are engaged and fixed. The number and position of the slots 20 correspond one-to-one with the number and position of the snap-fit ​​18.

[0040] The storage box 1 is provided with an outer cover plate 19, which covers the outside of the receiving cavity 10 to seal the receiving cavity 10, ensuring that the interior of the box 3 is not disturbed by the outside and improving the overall airtightness of the structure.

[0041] To facilitate the separation of the inserted storage box 1 from the box body 3, the box body 3 is provided with a relief groove 14 on one side corresponding to the outer cover plate 19. When the storage box 1 needs to be pulled out, the relief groove 14 can provide a force support point to facilitate the separation of the storage box 1 from the box body 3.

[0042] The storage box 1 has a connecting hole 12 corresponding to the position of the external air duct 8. An internal air duct 17 is connected to the connecting hole 12 and is connected to the external air duct 8 to transport the adsorbed waste into the storage box 1. The function of the internal air duct 17 is to prevent the adsorbed waste from falling back to the adsorption port 11 directly through the connecting hole 12 when the vacuum device 2 stops running.

[0043] The storage box 1 has a first filter port 13 located in the position corresponding to the vacuum device 2. The first filter port 13 is equipped with a filter 15, which is connected to the vacuum device 2 to prevent the garbage from being drawn out of the storage box 1 along with the airflow when the vacuum device 2 generates negative pressure. The first filter port 13 has a mesh structure, which can play a certain filtering role.

[0044] The housing 3 is provided with a second filter port 16 at the outlet position of the vacuum device 2. The second filter port 16 has a mesh structure, which can further play a filtering role.

[0045] In this application, the sensing device 9 includes a transmitter and a receiver. The transmitter is used to emit a light source, and the receiver is used to receive the reflected light source. The light source emitted by the transmitter extends in the direction directly towards the adsorption port 11. In order to improve the accuracy of sensing and recognition and avoid external interference, the light source emitted by the transmitter is a 940nm wavelength light source, and the light source received by the receiver is only a 940nm wavelength light source.

[0046] In this application, the transmitter and receiver are integrated into one unit. In other embodiments, the transmitter and receiver can also be set up independently. The choice can be made based on actual application requirements, and this application does not limit this.

[0047] As shown in Figure 5, the maximum detection distance of the transmitter is D, and the sensing detection distance obtained by detecting the location of the garbage is d. Based on the comparison between the sensing detection distance and the maximum detection distance, a distance detection result is obtained. If the distance detection result is d≤D, the sensing device 9 feeds back a signal to the PCB assembly 6 and controls the vacuuming device 2 to start accordingly to adsorb the detected garbage. It should be noted that if the distance between the location of the garbage and the sensing device 9 is greater than D, the sensing device 9 will not detect, and at this time it can be considered that the garbage does not belong to the object to be adsorbed, and the vacuuming device 2 will not be started.

[0048] In this application, the sensing device 9 is further configured to acquire an initial environmental reflection value corresponding to the position of the adsorption port 11 as a reference value when the switch assembly 7 is first turned on (initial state). The environmental reflection value characterizes the reflection state at the position of the adsorption port 11. Subsequently, when the switch assembly 7 is in the powered-on state, based on the detection of the position of the adsorption port 11, if there is garbage, the environmental reflection value corresponding to the position of the adsorption port 11 will change. The presence of garbage is determined by comparing the newly acquired environmental reflection value with the reference value. It should be noted that, to avoid detection errors, this application determines a detection threshold range based on actual needs. The environmental detection result is obtained by comparing the difference between the environmental reflection value and the reference value with the detection threshold. When the difference between the acquired environmental reflectance value and the reference value is not less than the detection threshold, the environmental detection result indicates the presence of garbage; otherwise, the environmental detection result indicates the absence of garbage. For example, if the reference value is B and the determined detection threshold range is 500, then if the acquired environmental reflectance value b ≥ B + 500, it is considered that garbage is present; if the acquired environmental reflectance value b < B + 500, it is considered that garbage is absent. If the acquired environmental reflectance value b ≥ B + 500 does not change after a preset time period, it can be considered that the adsorption port 11 is blocked and adsorption needs to be stopped. By detecting the environmental reflectance value through the sensing device 9, this application can confirm whether there is a blockage problem in the adsorption port 11, thereby responding quickly and resolving the issue promptly.

[0049] The PCB assembly 6 includes a processor and corresponding functional components to provide basic logic judgment functions and communication transmission functions.

[0050] The function selection module 5 and the switch assembly 7 are used for function selection and switch control, respectively, and both achieve function selection or switch control through the function of physical switches. For example, the function selection module 5 uses a knob structure to select functions, including switching between manual and automatic switch modes for garbage adsorption. If it is in automatic switch mode, the vacuum device 2 and the sensing device 9 will operate automatically. If it is in manual switch mode, the switch assembly 7 needs to be manually turned on to perform garbage adsorption. For example, the switch assembly 7 uses a button structure to control the operation of the vacuum device 2, allowing manual start-up or shutdown.

[0051] The intelligent waste adsorption device described in this application uses a sensing device 9 to collect the sensing detection distance and environmental reflection value corresponding to the adsorption port 11 position of the housing 3. The sensing detection distance is compared with the maximum detection distance to obtain a distance detection result. The difference between the environmental reflection value and the benchmark reference value is compared with the detection threshold to obtain an environmental detection result. The operating state of the vacuuming device 2 is determined based on the distance detection result and the environmental detection result. Based on the operating state of the vacuuming device 2, it is determined whether to automatically adsorb the waste at the adsorption port 11. The adsorption of micro-waste is achieved through the negative pressure generated by the vacuuming device 2. The sensing device 9 automatically controls the operating state of the vacuuming device 2. This device not only has high detection accuracy but also a high level of intelligent automation. The overall structure is simple and compact, with a reasonable layout, and has good application prospects.
