[0020] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0021] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0022] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and 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, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0024] Please also refer to Figures 1 to 4 The dust box overflow detection mechanism provided in the embodiment of the present application is now described. The dust box overflow detection mechanism comprises: a dust box 2 and a detection device provided on the dust box 2.

[0025] Specifically, the detection device includes a box body 7, a light guide panel 4, a scraper assembly, a drive unit 9 and a photoelectric sensor 10. The drive unit 9 and the photoelectric sensor 10 are arranged in the box body 7, the light guide panel 4 is arranged on the box body 7, the scraper assembly is movably arranged on the light guide panel 4 and is connected to the output shaft of the drive unit 9, and the photoelectric sensor 10 is used to perform photoelectric detection on the dust box 2 through the light guide panel 4.

[0026] It is understood that the box body 7 can isolate and seal the drive unit 9 and the photoelectric sensor 10. When the dust box 2 contains a large amount of dust, sewage, and other impurities, which contaminate the light guide panel 4, it will affect its light guiding performance and, in turn, the detection accuracy of the photoelectric sensor 10. In this case, the drive unit 9 can drive the scraper assembly to rotate, and the scraper assembly can be used to scrape the dirt off the surface of the light guide panel 4.

[0027] If the photoelectric sensor 10 does not detect any obstruction after the scraper assembly is scraped, it indicates that the light guide panel 4 is contaminated and interfered with. However, if the photoelectric sensor 10 still detects any obstruction after the scraper assembly is scraped, it can be confirmed that the dust box 2 is indeed overflowing. In this way, the accuracy of the dust box 2 overflow detection can be improved.

[0028] For example, the light guide panel 4 is a glass panel, which has the advantage of good light guiding performance. For example, the driving unit 9 is a servo motor, which has the advantage of high control accuracy.

[0029] In another embodiment of this application, please refer to Figure 4 A sealing ring 8 is provided between the light guide panel 4 and the box body 7 .

[0030] It can be understood that the sealing performance between the light guide panel 4 and the box body 7 is improved by the sealing ring 8 .

[0031] In another embodiment of this application, please refer to Figure 4 The scraper assembly includes a scraper frame 5 and a silicone scraper 3. The scraper frame 5 is connected to the output shaft of the driving unit 9, and the silicone scraper 3 is detachably arranged on the scraper frame 5.

[0032] It is understandable that the driving unit 9 can drive the scraper frame 5 to rotate, and the scraper frame 5 drives the silicone scraper 3 to clean the light guide panel 4. When the silicone scraper 3 is worn too much, it can be disassembled and replaced for easy maintenance.

[0033] In another embodiment of this application, please refer to Figures 1 to 4 There are two detection devices, which are symmetrically arranged on both sides of the dust box 2. The photoelectric sensor 10 of one detection device is a light projector, and the photoelectric sensor 10 of the other detection device is a light receiver. The light projector and the light receiver are arranged opposite to each other.

[0034] It is understandable that the light projector emits a sensing light, which may be infrared light or laser light, and the light receiver is used to receive the sensing light, thereby detecting whether the dust box 2 is full.

[0035] In another embodiment of this application, please refer to Figure 1 At least one acoustic wave sensor 1 is further provided on the top of the dust box 2, and the acoustic wave sensor 1 is used for performing acoustic wave detection from top to bottom.

[0036] It is understandable that the acoustic wave sensor 1 is used to detect the overflow degree of the dust box 2 from top to bottom using acoustic waves, which intersects with the horizontal detection of the photoelectric sensor 10 to improve the accuracy of the dust box 2 overflow detection.

[0037] The present application also provides an intelligent robot, which includes a controller and the dust box overflow detection mechanism as described above, and the controller is connected to the driving unit 9 and the photoelectric sensor 10 respectively.

[0038] It is understandable that when the photoelectric sensor 10 detects that the dust box 2 is full and feeds back to the controller, the controller can control the driving unit 9 to clean the light guide panel 4, and the photoelectric sensor 10 performs dust box 2 overflow detection again to improve detection accuracy.

[0039] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
