[0025] Examples

[0026] An embodiment of the present application provides a portable cleaning device (10), and as shown in FIG. 1, the device includes a storage container (11), a spray structure (12), and an installation mechanism (14).

[0027] A liquid storage chamber (111) for holding cleaning liquid is formed in the storage container (11), and a liquid inlet is formed at the top of the storage container (11). A rotating cover (114) is detachably installed at the liquid inlet, and the liquid inlet can be sealed through a screw connection between the rotating cover (114) and the storage container (11). When in use, the rotating cover (114) can be opened to fill the liquid storage chamber (111) with cleaning liquid. A first control valve is installed at the liquid outlet of the liquid storage chamber (111), and the first control valve can open or close the liquid outlet. Optionally, the size of the storage container (11) is 5~10cm*5~10cm*5~10cm.

[0028] For example, the liquid storage chamber (111) includes a first liquid storage chamber (1111) for holding water and a second liquid storage chamber (1112) for holding detergent, and the outlet of the first liquid storage chamber (1111) and the outlet of the second liquid storage chamber (1112) are connected through a connecting passage (1113), and a second control valve is installed at the outlet of the first liquid storage chamber (1111), and a third control valve is installed at the outlet of the second liquid storage chamber (1112). The first control valve is installed in the connecting passage (1113). The portable cleaning device (10) further includes a controller, and the controller is connected to the first control valve, the second control valve, and the third control valve by a signal.

[0029] The opening and closing of the first control valve, the second control valve, and the third control valve can be controlled through the controller, thereby regulating the flow of water and detergent. If only water from the first liquid storage chamber (1111) needs to be discharged, the controller opens the second control valve and the first control valve and closes the third control valve. If water from the first liquid storage chamber (1111) and detergent from the second liquid storage chamber (1112) need to be mixed to create a cleaning solution, the controller opens the first control valve, the second control valve, and the third control valve. Optionally, a control switch may be further included, and the control switch is connected to the controller via communication (e.g., electrical connection, Bluetooth connection, or Wi-Fi connection). The first control valve, the second control valve, and the third control valve can be controlled by operating the controller through the control switch. Here, the control switch may be a mechanical switch or a touch screen switch, etc.

[0030] The spray structure (12) is connected to the bottom of the liquid storage container (11), and the spray structure (12) includes a spray head (121), the spray head (121) can rotate relative to the storage container (11) when spraying water, and the spray head (121) includes a water outlet (1211) and a brush part (1212), and the water outlet (1211) and the brush part (1212) are alternately arranged along the vertical direction of the spray head (121). A water outlet hole (1211a) arranged in an array form is formed in the water outlet (1211), the water outlet hole (1211a) is connected to the liquid storage chamber (111), and a brush (1212a) is formed in the brush part (1212) (see FIG. 1 and FIG. 2).

[0031] The installation mechanism (14) includes an installation plate (141) and a plurality of suction plates (142) installed at the bottom of the installation plate (141). The installation plate (141) is connected to a storage container (11) and arranged in an annular shape around a spray structure (12). The plurality of suction plates (142) can form an annular shape that contacts each other when adsorbed to a target surface, and the brush (1212a) can contact the target surface (see FIGS. 1 and 3). Optionally, the height of the installation plate (141) is 5 to 10 cm and the thickness is 1 to 3 cm. An airflow passage (1411) is formed inside the installation plate (141), and the airflow passage (1411) is connected to the suction plates (142). A switch structure (16) capable of connecting or blocking the airflow passage (1411) to the outside is additionally installed on the installation plate (141) (see FIGS. 4 to 7). By controlling the switch structure (16) to connect the airflow passage (1411) to the outside, the airflow passage (1411) can be connected to the outside through the switch structure (16) when the suction plate (142) needs to release the suction state while it is in a state of suction on the target surface, and the suction plate (142) can be removed relatively easily when air is introduced. Here, a main passage and a plurality of branch passages are formed in the airflow passage (1411), and the branch passages are connected to each suction plate (142), and all of the plurality of branch passages are connected to the main passage.

[0032] When using the portable cleaning device (10) of the present application, water is filled into the first liquid storage chamber (1111), a cleaning agent is placed into the second liquid storage chamber (1112), and the rotating cover (114) is closed. The opening and closing of the first control valve, the second control valve, and the third control valve are controlled through a controller to discharge water and / or the cleaning agent. A plurality of suction plates (142) are formed at the bottom of the mounting plate (141) to fix the cleaning device to the target surface by suction force. Additionally, the water outlet (1211) and brush (1212) of the spray head (121) are alternately arranged in the radial direction of the spray head (121), and the water outlet hole (1211a) is connected to the storage chamber (111). When the spray head (121) rotates relative to the storage container (11) to spray water, the water sprayed from the water outlet hole (1211a) is sprayed outward by centrifugal force, and the cleaning liquid adheres to the brush, allowing the target surface to be cleaned more effectively. Additionally, when the suction plate (142) adheres to the target surface, a ring shape is formed in contact with each other, and the mounting plate (141) surrounds the spray structure (12), so the cleaning liquid sprayed from the water outlet hole (1211a) accumulates inside the ring-shaped mounting plate (141) and is difficult to leak. As a result, contaminants on the target surface (e.g., fruit juice on the vehicle surface, bird droppings, etc.) are soaked simultaneously with cleaning, thereby obtaining a better cleaning effect. When cleaning is finished, the airflow passage (1411) can be connected to the outside atmosphere through the switch structure (16) to easily detach the suction plate (142). In addition, the portable cleaning device (10) of the present application can be carried in a vehicle, and is convenient to use as there is no need for a person to brush during cleaning. Furthermore, due to the suction force of the suction plate (142), the range of target surfaces selected is wide, allowing various surfaces such as vehicle surfaces, floors, and walls to be cleaned.

[0033] Here, the spray head (121) may be a rotary spray head (121), and the rotary spray head (121) is connected to the storage container (11). The spray head (121) may rotate relative to the storage container (11) when spraying water. In another embodiment, the spray structure (12) includes a connecting pipe (122) and a spray head (121), and the connecting pipe (122) is rotatably connected to the bottom of the storage container (11) so that the spray head (121) may rotate relative to the storage container (11). For example, a liquid discharge pipe (112) is formed in the bottom of the storage container (11), and the liquid discharge pipe (112) is connected to the connecting pipe (122) via a sealed rotary bearing (113). A fluid passage is formed in the connecting pipe (122), and the fluid passage connects the liquid storage chamber (111) and the water outlet (1211a) of the spray head (121). The portable cleaning device (10) further includes a driving mechanism (15), and the driving mechanism (15) is configured to rotate the connecting pipe (122). By the driving mechanism (15) rotating the connecting pipe (122), the spray head (121) rotates relative to the bottom of the liquid storage chamber (111), and the water sprayed from the outlet hole (1211a) is scattered outward by centrifugal force, allowing the cleaning liquid to adhere to the brush and the target surface to be cleaned better.

[0034] For example, a first bevel gear (1223) is fixedly installed on the outer wall of a connecting pipe (122), and the driving mechanism (15) includes a driving component (151) and a second bevel gear (152) connected to the power output terminal of the driving component (151). The first bevel gear (1223) and the second bevel gear (152) mesh with each other, and the rotation axes of the second bevel gear (152) and the second bevel gear (152) are formed perpendicular to each other, and the driving component (151) is installed on the outer wall of a mounting plate (141). Here, the driving component (151) is a motor, the rotation axis of the second bevel gear (152) is set horizontally, and the rotation axis of the first bevel gear (1223) is set vertically. Since the driving part (151) can rotate the second bevel gear (152) to rotate the first bevel gear (1223), the connecting pipe (122) can rotate so that the spray head (121) can rotate relative to the bottom of the liquid storage room (111).

[0035] Additionally, in some embodiments, the switch structure (16) includes a pressing part (161) and a spring (162), and an installation hole (1412) connected to an airflow passage (1411) is formed in the outer wall of the mounting plate (141). Optionally, the installation hole (1412) is formed corresponding to the main passage. The pressing part (161) includes a connected pressing accessory (1611) and a connecting part (1612), and the spring (162) is installed in the connecting part (1612). Additionally, one end of the spring (162) is connected to the inner wall of the airflow passage (1411), and the other end is supported by a pressing accessory (1611). The pressing accessory (1611) includes a pressing block (16111) and a supporting block (16112). The pressing block (16111) is formed in the installation hole (1412), and the supporting block (16112) is supported on the side of the airflow passage (1411) of the installation plate (141) by the elasticity of the spring (162). Additionally, when the pressing block (16111) is pressed, the supporting block (16112) moves away from the outer wall of the installation plate (141), creating a gap between the pressing block (16111) and the wall of the airflow passage (1411) of the installation hole (1412).

[0036] When the support block (16112) moves away from the outer wall of the mounting plate (141) by pressing the pressing block (16111), a gap is formed between the pressing block (16111) and the wall of the airflow passage (1411) of the mounting hole (1412). Through this gap, external air flows into the airflow passage (1411), allowing the suction plate (142) to be easily detached. When the hand is released from the pressing block (16111), the support block (16112) moves toward one side of the airflow passage (1411) while pressing against the mounting plate (141) due to the action of the spring (162), thereby blocking the connection between the outside and the airflow passage (1411).

[0037] In one embodiment, one end of the outer wall of the pressing block (16111) near the mounting plate (141) is the first stage (163), and one end of the pressing block (16111) near the airflow passage (1411) is the second stage (164), the outer diameter of the second stage (164) is larger than the inner diameter of the first stage (163), and the outer diameter of the first stage (163) is smaller than the inner diameter of the mounting hole (1412). When the pressing block (16111) is pressed so that the first stage (163) approaches the airflow passage (1411), a gap is formed between the pressing block (16111) and the wall of the airflow passage (1411) of the mounting hole (1412) (see FIG. 4 and FIG. 5). In another embodiment, the outer diameter of the pressing block (16111) is smaller than the inner diameter of the installation hole (1412) (see FIG. 6 and FIG. 7), so that when pressed for only a very short distance, a gap is formed between the pressing block (16111) and the wall of the airflow passage (1411) of the installation hole (1412).

[0038] Accordingly, the portable cleaning device (10) of the present application can hold cleaning liquid in the liquid storage chamber (111) when in use, and a plurality of suction plates (142) are formed on the bottom of the mounting plate (141), so that the cleaning device can be fixed to the target surface by the suction action of the suction plates (142). In addition, the water outlet (1211) and the brush part (1212) of the spray head (121) are alternately arranged in the vertical direction of the spray head (121), and the water outlet hole (1211a) is connected to the liquid storage chamber (111), so that when the spray head (121) rotates relative to the storage container (11) when spraying water, the water sprayed from the water outlet hole (1211a) is scattered outward by centrifugal force, allowing the cleaning liquid to adhere to the brush and the target surface to be cleaned more effectively. In addition, when the suction plate (142) is adsorbed to the target surface, it forms a ring shape that comes into contact with each other, and since the mounting plate (141) is arranged in a ring shape around the spray structure (12), the cleaning liquid sprayed from the water outlet (1211a) accumulates inside the ring-shaped mounting plate (141), so the cleaning liquid does not easily leak out, allowing contaminants (e.g., fruit juice from a vehicle, bird droppings, etc.) on the target surface to be submerged during cleaning, thereby obtaining a better cleaning effect. Furthermore, the portable cleaning device (10) of the present application can be carried in a vehicle and is convenient to use as it does not require a process of rubbing by a person during cleaning.

[0039] The foregoing is merely a preferred embodiment of the present application and is not intended to limit the application. Those skilled in the art may make various changes or modifications to the present application. All modifications, equivalent substitutions, improvements, etc., that are consistent with the spirit and principles of the present application will fall within the scope of protection of the present application.
