[0057] Please refer to Figure 1 This application proposes a passive cleaning device 100, including a cleaning part 10 and a handheld part 20. The cleaning part 10 is used to clean the surface to be cleaned, and the handheld part 20 is connected to the cleaning part 10.

[0058] The passive cleaning device 100 is a cleaning device that requires user participation and operation. The user needs to hold the handheld part 20 and push the cleaning part 10 across the surface to be cleaned. The passive cleaning device 100 includes, but is not limited to, handheld floor scrubbers, handheld vacuum cleaners, or handheld mite removers. Correspondingly, the surface to be cleaned can be a floor, wall, window, etc.

[0059] It should be noted that the connection between the handheld part 20 and the cleaning part 10 can be either a movable connection or a fixed connection. The movable connection includes, but is not limited to, a rotating connection and a detachable connection, which can be specifically set according to actual needs. The type of cleaning part 10 can be set according to actual needs, as long as it is a component that can clean the surface to be cleaned, such as a roller brush or a mop.

[0060] In one implementation, the passive cleaning device 100 is a floor scrubber, which includes a mopping component that forms at least a partial cleaning section 10. The mopping component is used to clean the surface to be cleaned. There can be one or more mopping components. For example, the mopping component is a roller brush. The mopping component is located at the bottom of the floor scrubber and cleans the surface as the passive cleaning device 100 moves over it.

[0061] Please refer to Figure 2The cleaning device 100 also includes a first lighting element 30, which is disposed on the cleaning part 10 and / or the handheld part 20. The first lighting element 30 is used to emit a first light beam toward the rear of the cleaning device 100, and the first light beam is used to illuminate at least part of the cleaned surface to be cleaned.

[0062] In this embodiment, the forward direction of the cleaning device 100 is forward, the opposite direction is backward, and the left-right direction is based on the forward-backward direction and is perpendicular to the forward-backward direction. For further understanding and explanation, ... Figure 2 For example, the cleaning equipment body 101 can be a rectangular, circular, or other shape. The cleaning equipment body 101 has a center line located in the left-right direction, and the traveling direction of the cleaning equipment 100 is... Figure 2 The forward and backward directions indicated by the arrows.

[0063] When using the passive cleaning device 100 to clean a surface in a dimly lit area, the first lighting element 30 can illuminate the rear of the cleaning device 100. When the first light shines on the dust or impurity particles on the cleaned surface, these particles can be observed with the naked eye, making it easy for the user to see whether the surface is clean and to compare the cleaning effect before and after cleaning in real time, so as to further clean the surface and improve cleaning efficiency and effect.

[0064] In existing cleaning equipment, the cleaning section (such as a roller brush) is generally located on the front or sides of the equipment body to achieve edge cleaning. To avoid affecting the edge cleaning function, in some embodiments, the first lighting element 30 is located behind the cleaning section 10, that is, behind the cleaning equipment 100 in the forward direction. This allows the first lighting element 30 to emit a first light beam towards the rear of the cleaning equipment 100, illuminating at least a portion of the cleaned surface to be cleaned. This achieves illumination of the area behind the cleaning equipment 100 without affecting the edge cleaning function, thus avoiding occupying space in the cleaning section 10. When positioned at a relatively low side, the first light beam illuminating the at least partially cleaned surface can cast shadows of dust or particles, creating a sharp contrast between the shadows and the surface to be cleaned. This provides a clear view of the area behind the cleaning equipment 100, allowing users to easily see whether the surface is clean and to observe and compare the cleaning effect before and after cleaning in real time.

[0065] Of course, in other embodiments, the first lighting element 30 may also be located on the left and / or right side of the cleaning part 10, or on the rear side of the handheld part 20, or simultaneously located on the rear side of both the cleaning part 10 and the handheld part 20. This application does not limit this.

[0066] In some embodiments, the handheld part 20 includes a gripping part 21 and a connecting part; the gripping part 21 is connected to the cleaning part 10 via the connecting part; in at least one working posture of the passive cleaning device 100, the vertical distance between the gripping part 21 and the surface to be cleaned is greater than 0.5m, which makes it convenient for the user to hold the gripping part 21 to clean the surface to be cleaned. This allows the user to see the surface to be cleaned even when the user is at a large distance from the surface to be cleaned, under the illumination of the first light.

[0067] In some embodiments, the number of first lighting elements 30 is one, or the number of first lighting elements 30 is two or more, and the two or more first lighting elements 30 may be distributed on opposite sides of the cleaning section 10. Of course, this is only exemplary and is not intended to limit the scope of this application.

[0068] In some embodiments, the height of the first illuminator 30 from the surface to be cleaned is greater than 0 mm and less than or equal to 6 mm. For example, the height of the first illuminator 30 from the surface to be cleaned is 1 mm, 3 mm, 4 mm, 6 mm, etc. In this embodiment, by controlling the distance between the first illuminator 30 and the surface to be cleaned, the visibility effect of the first illuminator 30 on the cleaned surface to be cleaned is ensured.

[0069] In some embodiments, the first illuminator 30 illuminates the first light beam at an angle downwards, increasing the illumination range of the first illuminator 30 and making it easier for the user to clean the already cleaned surface to be cleaned.

[0070] Preferably, the direction of the central light emitted from the first illuminator 30 is set at an acute angle to the left-right direction of the cleaning section 10, such as 45°, 50°, 55°, 60°, etc. The size of the acute angle is set according to the actual situation to adjust the illumination range of the first illuminator 30.

[0071] In some embodiments, the first lighting element 30 includes a first laser light that emits a first light. Since the light emitted by the first laser light is more focused than that of an ordinary light, the first light illuminates the cleaned surface to be cleaned. The high energy and high brightness of the laser can make fine particles and dust on the ground visible. After cleaning the surface to be cleaned, it can also help users check whether the surface has been truly cleaned, thus meeting the user's need for deep cleaning and improving cleaning efficiency and effectiveness.

[0072] Of course, in other embodiments, the first lighting element 30 may also be an LED light, and this application embodiment does not limit it here.

[0073] In some embodiments, the first light source is green light. Illuminating dust and impurities with green light enhances the contrast between light and shadow, creating a sharp contrast between the shadows of the dust and impurities and the cleaned surface to be cleaned. This significantly improves the visibility of the dust, making it easier for users to see and clean more effectively. Simultaneously, the soft and uniform green light provides a more comfortable viewing experience for the user during cleaning.

[0074] In some embodiments, the wavelength of the first light is between 532nm and 556nm, for example, the wavelengths of the first light are 532nm, 544nm, 555nm, and 556nm. The first light in this wavelength range is green laser light, which has a bright beam and strong resistance to stray light interference. Compared with white light, which has higher brightness, users are more sensitive to the first light with a wavelength between 532nm and 556nm, which helps users to detect dust and impurities on a cleaned surface, thereby enabling deep cleaning.

[0075] In some embodiments, the first lighting element 30 is a first light strip, which is arranged along the left-right direction of the cleaning section 10. This increases the light-emitting area of ​​the first lighting element 30, improves its lighting effect, and ensures uniform light emission, thereby improving the lighting quality and facilitating the illumination of dust and impurity particles on the surface to be cleaned. This embodiment only provides a specific shape selection for the first lighting element 30, but is not limited thereto.

[0076] In some embodiments, please refer to Figure 3 The passive cleaning device 100 includes a light intensity detection device 40 and a light intensity control module 50. The light intensity detection device 40 is used to detect the ambient light intensity. The light intensity control module 50 is connected to the light intensity detection device 40 and the first lighting element 30 respectively, and is used to adjust the light intensity of the first lighting element 30 according to the ambient light intensity detected by the light intensity detection device 40.

[0077] In this embodiment, the cleaning equipment 100 detects the ambient light intensity through the light intensity detection device 40, and the light intensity detection device 40 sends a light intensity signal to the light intensity control module 50. The light intensity control module 50 then adjusts the light intensity of the first illuminator 30 according to the light intensity signal detected by the light intensity detection device 40.

[0078] The light intensity control module 50 can be electrically connected to the light intensity detection device 40 and the first illumination element 30 via wired or wireless means, depending on the actual situation. Light intensity control of the first illumination element 30 can include turning it on or off, adjusting its brightness, etc., that is, adjusting the on / off state and brightness of the first illumination element 30 according to the ambient light level, thus saving energy. Of course, in other embodiments, it can also include adjusting the color of the first illumination element 30, depending on the actual situation.

[0079] In some embodiments, please refer to Figure 4 The passive cleaning device 100 includes a trigger 60 and a light intensity control module 50. The trigger 60 is used to collect the switch signal triggered by the user. The light intensity control module 50 is connected to the trigger 60 and the first lighting element 30 respectively, and is used to control the light intensity of the first lighting element 30 according to the switch signal collected by the trigger 60.

[0080] In this embodiment, the cleaning device 100 collects the switch signal triggered by the user through the trigger 60, the light intensity detection device 40 sends the switch signal to the light intensity control module 50, and the light intensity control module 50 adjusts the light intensity of the first lighting element 30 according to the switch signal detected by the trigger 60.

[0081] The light intensity control module 50 can be electrically connected to the trigger 60 and the first illumination element 30 via wired or wireless means, depending on the actual situation. Light intensity control of the first illumination element 30 can include turning it on or off, adjusting its brightness, etc., that is, adjusting the on / off state and brightness of the first illumination element 30 according to the ambient light level, thus saving energy. Of course, in other embodiments, it can also include adjusting the color of the first illumination element 30, depending on the actual situation.

[0082] For example, the trigger 60 can be configured as a control button, allowing the user to manually control the first lighting element 30 to turn on or off or adjust the brightness of the first lighting element 30 by pressing the control button.

[0083] In some embodiments, please refer to Figure 5 The cleaning device 100 also includes a second lighting element 70, which is disposed on the handheld part 20 and / or the cleaning part 10; the second lighting element 70 is used to illuminate a second light towards a local surface to be cleaned in front of the cleaning device 100.

[0084] When cleaning the surface to be cleaned, the second light emitted by the second lighting element 70 illuminates the area to be cleaned in front of the cleaning device 100, which can achieve a better lighting effect on the area to be cleaned. This makes it easier for users to judge whether the surface to be cleaned is clean and to carry out targeted cleaning, which helps to improve the efficiency of cleaning the surface to be cleaned.

[0085] In this embodiment, the second lighting element 70 is used in conjunction with the first lighting element 30 to illuminate the surface to be cleaned and the cleaned surface to be cleaned, respectively. This allows for a clear view of the effect of the surface before and after cleaning, enabling further cleaning of the surface and further improving cleaning efficiency and effectiveness.

[0086] In some embodiments, the second illuminator 70 is located on the front side of the cleaning section 10 and is used to illuminate a second light source toward a portion of the surface to be cleaned in front of the cleaning device 100. Of course, in other embodiments, the second illuminator 70 may also be located on the left or right side of the cleaning section 10, as long as it can emit a second light source toward the area to be cleaned in front of the cleaning device 100 to make the dust and impurity particles in the area to be cleaned visible. This application does not limit this.

[0087] In some embodiments, the second lighting element 70 includes a second light strip, which is disposed along the left-right direction of the cleaning section 10. This increases the light-emitting area of ​​the second lighting element 70, improves its lighting effect, and ensures uniform light emission, thereby enhancing the lighting quality and making dust and impurity particles on the surface to be cleaned more visible. This embodiment only provides a specific shape selection for the second lighting element 70, but is not limited thereto.

[0088] In some embodiments, the height of the second illuminator 70 from the surface to be cleaned is greater than 0 mm and less than or equal to 6 mm. For example, the height of the second illuminator 70 from the surface to be cleaned is 1 mm, 3 mm, 4 mm, 6 mm, etc. In this embodiment, by controlling the distance between the second illuminator 70 and the surface to be cleaned, it is ensured that the second illuminator 70 can make dust and impurity particles on the surface to be cleaned visible.

[0089] In some embodiments, the second lighting element 70 illuminates the second light beam at an angle downwards, increasing the illumination range of the second lighting element 70 and making it easier for the user to clean the surface to be cleaned.

[0090] In some embodiments, the emission direction of the central light of the second illuminator 70 is set at an acute angle to the left-right direction of the cleaning section 10, such as 45°, 50°, 55°, 60°, etc. The size of the acute angle is set according to the actual situation to adjust the illumination range of the second illuminator 70.

[0091] In some embodiments, the second lighting element 70 includes a second laser lamp that emits a second light beam. The light beam is more focused and illuminates the surface to be cleaned. The high energy and high brightness of the laser can make fine particles and dust on the ground visible, allowing users to see whether the surface is clean. This eliminates the need for repeated cleaning, saving time and effort, and thus improving cleaning efficiency and effectiveness.

[0092] Of course, in other embodiments, the second lighting element 70 may also be an LED light, and this application embodiment does not limit it here.

[0093] In some embodiments, the second light is green light. Illuminating dust and impurities with green light enhances the contrast between light and shadow, creating a sharp contrast between the shadows of dust and impurities and the surface to be cleaned. This significantly improves the visibility of dust, making it easier for users to see and clean more effectively. Simultaneously, the soft and uniform green light provides a more comfortable viewing experience for users during cleaning.

[0094] In some embodiments, the wavelength of the second light is between 532nm and 556nm, for example, the wavelengths of the second light are 532nm, 544nm, 555nm, and 556nm. The second light within this wavelength range is green laser light, which has a bright beam and strong resistance to stray light interference. Compared to brighter white light, users are more sensitive to second light with wavelengths between 532nm and 556nm, which helps users detect dust and impurities on the surface to be cleaned, thus facilitating cleaning.

[0095] This application also provides a cleaning system, which includes a passive cleaning device 100 as described above and a base station. The base station includes a docking position where the cleaning device 100 can dock. The base station is used in conjunction with the passive cleaning device 100. After cleaning the surface to be cleaned, the passive cleaning device 100 discharges the resulting solid-liquid mixture of hair, wastewater, etc., into the base station. Furthermore, the base station can also be used to maintain the cleaning part 10 of the passive cleaning device 100, such as cleaning or replacing the cleaning part 10. For example, the base station can also charge the passive cleaning device 100, and / or provide a docking position for the passive cleaning device 100. For instance, the passive cleaning device 100 can dock at the base station's docking position when charging, docking, or undergoing maintenance, and leave the base station's docking position when performing cleaning tasks, such as mopping. This is merely one embodiment; specific implementations include, but are not limited to, this.

[0096] Since the cleaning system adopts all the technical solutions of all embodiments of the above-mentioned passive cleaning equipment 100, the cleaning system of this utility model also has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.

[0097] The above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is impossible to exhaustively list all possible implementations here. All obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
