[0035] Example

[0036] The present application embodiment provides a portable cleaning device 10, please refer to Figure 1 , which includes a liquid reservoir 11, a spraying structure 12 and a mounting mechanism 14.

[0037] The liquid reservoir 11 has a liquid storage chamber 111 for containing cleaning liquid, wherein the top of the liquid reservoir 11 has a liquid inlet, and the liquid inlet is detachably installed with a rotating cover 114, which is threadedly connected to the liquid reservoir 11 by the rotating cover 114, so that the liquid inlet can be closed. When in use, the rotating cover 114 is unscrewed, and the cleaning liquid can be filled into the liquid storage chamber 111. The liquid outlet of the liquid storage chamber 111 is installed with a first control valve, and the first control valve can control the opening or closing of the liquid outlet. Optionally, the size of the liquid reservoir 11 is 5-10cm*5-10cm*5-10cm.

[0038] Exemplarily, the liquid storage chamber 111 includes a first liquid storage chamber 1111 for holding water and a second liquid storage chamber 1112 for holding a cleaning agent. The outlet of the first liquid storage chamber 1111 and the outlet of the second liquid storage chamber 1112 are connected through a connecting channel 1113. The outlet of the first liquid storage chamber 1111 is provided with a second control valve, and the outlet of the second liquid storage chamber 1112 is provided with a third control valve. The first control valve is provided in the connecting channel 1113; the portable cleaning device 10 also includes a controller, and the controller is signal-connected to the first control valve, the second control valve and the third control valve.

[0039] The controller can control the opening and closing of the first control valve, the second control valve and the third control valve, so as to control the flow of water and cleaning agent. When only the water in the first liquid storage chamber 1111 needs to be released, the controller controls the second control valve and the first control valve to open, and controls the third control valve to close; when the water in the first liquid storage chamber 1111 and the cleaning agent in the second liquid storage chamber 1112 need to be released to mix and form a cleaning liquid, the controller controls the first control valve, the second control valve and the third control valve to open. Optionally, a control switch is also included, and the control switch is communicatively connected with the controller, for example, it can be an electrical connection, a Bluetooth connection or a wifi connection. The controller can be operated by the control switch to control the closing of the first control valve, the second control valve and the third control valve. Among them, the control switch can be a mechanical switch, or a touch screen switch, etc.

[0040] The spray structure 12 is connected to the bottom of the liquid reservoir 11. The spray structure 12 includes a spray head 121. The spray head 121 can rotate relative to the liquid reservoir 11 when spraying water. The spray head 121 includes a water outlet area 1211 and a brush area 1212. The water outlet area 1211 and the brush area 1212 are alternately arranged along the radial direction of the spray head 121. The water outlet area 1211 has water outlet holes 1211a arranged in an array. The water outlet holes 1211a can be connected to the liquid storage chamber 111. The brush area 1212 is provided with brushes 1212a (refer to Figure 1 and Figure 2 ).

[0041] The mounting mechanism 14 includes a mounting plate 141 and a plurality of suction cups 142 disposed at the bottom of the mounting plate 141. The mounting plate 141 is connected to the liquid reservoir 11 and is disposed around the spraying structure 12. When the plurality of suction cups 142 adsorb the target surface, they can form a ring shape that contacts each other, and the bristles 1212a can contact the target surface (refer to Figure 1 and Figure 3 Optionally, the height of the mounting plate 141 is 5 to 10 cm and the thickness is 1 to 3 cm. An airflow channel 1411 is provided inside the mounting plate 141, and the airflow channel 1411 is connected to the suction cup 142; the mounting plate 141 is also provided with a switch structure 16 (see Figure 4-Figure 7 ). By controlling the switch structure 16, the airflow channel 1411 can be connected to the outside world. When the suction cup 142 is sucking the target surface and needs to release the sucking state, the airflow channel 1411 can be connected to the outside world through the switch structure 16. After the air enters, the suction cup 142 is easier to be unplugged. Among them, the airflow channel 1411 has a main channel and multiple branch channels, the branch channels are connected to each suction cup 142, and the multiple branch channels are all connected to the main channel.

[0042] The portable cleaning device 10 of the present application can be filled with water in the first liquid storage chamber 1111, the cleaning agent can be filled in the second liquid storage chamber 1112, and then the rotating cover 114 can be closed. The switches of the first control valve, the second control valve and the third control valve can be controlled by the controller to release water and / or cleaning agent. Since the bottom of the mounting plate 141 has a plurality of suction cups 142, the cleaning device can be fixed to the target surface by the adsorption effect of the suction cups 142. In addition, the water outlet area 1211 and the brush area 1212 of the spray head 121 are alternately arranged along the radial direction of the spray head 121, and the water outlet hole 1211a can be connected to the liquid storage chamber 111. When the spray head 121 sprays water, it rotates relative to the liquid storage chamber 11, and the water sprayed from the water outlet hole 1211a is sprayed outward under the action of centrifugal force, so that the brush can be stained with the cleaning liquid, thereby better cleaning the target surface. Moreover, since the suction cup 142 is adsorbed on the target surface to form a ring in contact with each other, and the mounting plate 141 is arranged around the spray structure 12, the cleaning liquid sprayed from the water outlet 1211a can be trapped in the ring-shaped mounting plate 141, and the cleaning liquid is not easy to leak out. The dirt on the target surface (such as fruit pulp on the car, bird excrement, etc.) can be soaked while cleaning, thereby achieving a better cleaning effect. After cleaning, the air flow channel 1411 can be controlled to communicate with the outside atmosphere through the switch structure 16, so that the suction cup 142 can be easily unplugged. Moreover, the portable cleaning device 10 of the present application can be carried with the car, and there is no need to use manual brushing to clean during cleaning, which is more convenient to use. It should be noted that due to the adsorption effect of the suction cup 142, the selectivity of the target surface is relatively large. For example, it can be used to clean the surface of the car, the ground, or the wall.

[0043] The spray head 121 may be a rotating spray head 121, which is connected to the liquid reservoir 11. The spray head 121 can rotate relative to the liquid reservoir 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 liquid reservoir 11, so that the spray head 121 can rotate relative to the liquid reservoir 11. Exemplarily, the bottom of the liquid reservoir 11 has a liquid outlet pipe 112, and the liquid outlet pipe 112 is connected to the connecting pipe 122 through a sealed rotating bearing 113. The connecting pipe 122 has a liquid flow channel, and the liquid flow channel can connect the liquid storage chamber 111 and the water outlet hole 1211a of the spray head 121; the portable cleaning device 10 also includes a driving mechanism 15, and the driving mechanism 15 is configured to drive the connecting pipe 122 to rotate. The connecting pipe 122 is driven to rotate by the driving mechanism 15, so that the spray head 121 rotates relative to the bottom of the liquid storage chamber 111, and the water sprayed from the water outlet 1211a is sprayed outward under the action of centrifugal force, so that the brush can be stained with cleaning liquid, thereby better cleaning the target surface.

[0044] Exemplarily, the outer wall of the connecting tube 122 is fixedly mounted with a first bevel gear 1223, the driving mechanism 15 includes a driving member 151 and a second bevel gear 152 connected to the power output end of the driving member 151, the first bevel gear 1223 and the second bevel gear 152 can mesh, the second bevel gear 152 and the second bevel gear 152 have a rotation axis that is perpendicular, and the driving member 151 is mounted on the outer wall of the mounting plate 141. The driving member 151 is a motor, the rotation axis of the second bevel gear 152 is arranged horizontally, and the rotation axis of the first bevel gear 1223 is arranged vertically. The second bevel gear 152 is driven to rotate by the driving member 151, thereby driving the first bevel gear 1223 to rotate, thereby causing the connecting tube 122 to rotate, and the spray head 121 to rotate relative to the bottom of the liquid storage chamber 111.

[0045] Further, in some embodiments, the switch structure 16 includes a pressing component 161 and a spring 162, and the outer wall of the mounting plate 141 is provided with a mounting hole 1412 connected to the air flow channel 1411, and optionally, the mounting hole 1412 is arranged corresponding to the main channel. The pressing component 161 includes a pressing piece 1611 and a connecting piece 1612 that are connected. The spring 162 is sleeved on the connecting piece 1612, and one end of the spring 162 is connected to the inner wall of the airflow channel 1411, and the other end of the spring 162 is abutted against the pressing piece 1611. The pressing piece 1611 includes a pressing block 16111 and a abutting block 16112. The pressing block 16111 is provided in the mounting hole 1412, and the abutting block 16112 can be abutted against a side of the mounting plate 141 facing the airflow channel 1411 under the elastic force of the spring 162; and when the pressing block 16111 is pressed to make the abutting block 16112 move away from the outer wall of the mounting plate 141, a gap can be formed between the pressing block 16111 and the hole wall of the mounting hole 1412 close to the airflow channel 1411.

[0046] When the pressing block 16111 is pressed to move the abutting block 16112 away from the outer wall of the mounting plate 141, a gap is formed between the pressing block 16111 and the hole wall of the mounting hole 1412 close to the airflow channel 1411, and the outside air can enter the airflow channel 1411 through the gap, so that the suction cup 142 can be pulled out more easily. When the pressing block 16111 is released, the abutting block 16112 can be abutted against the side of the mounting plate 141 facing the airflow channel 1411 under the action of the spring 162, so that the outside and the airflow channel 1411 are cut off.

[0047] In one embodiment, the end of the pressing block 16111 close to the outer wall of the mounting plate 141 is the first end 163, and the end of the pressing block 16111 close to the airflow channel 1411 is the second end 164. The outer diameter of the second end 164 is greater than the inner diameter of the first end 163, and the outer diameter of the first end 163 is smaller than the inner diameter of the mounting hole 1412. When the pressing block 16111 is pressed so that the first end 163 of the pressing block 16111 is close to the airflow channel 1411, a gap can be formed between the pressing block 16111 and the hole wall of the mounting hole 1412 close to the airflow channel 1411 (see Figure 4 and Figure 5 In other embodiments, the outer diameter of the pressing block 16111 is smaller than the inner diameter of the mounting hole 1412 (see Figure 6 and Figure 7 ), a short pressing distance is required to form a gap between the pressing block 16111 and the hole wall of the mounting hole 1412 close to the air flow channel 1411.

[0048] In summary, the portable cleaning device 10 of the present application can be used to hold the cleaning liquid in the liquid storage chamber 111. Since the bottom of the mounting plate 141 has a plurality of suction cups 142, the cleaning device can be fixed to the target surface through the adsorption effect of the suction cups 142. In addition, the water outlet area 1211 and the brush area 1212 of the spray head 121 are alternately arranged along the radial direction of the spray head 121, and the water outlet hole 1211a can be connected to the liquid storage chamber 111. When the spray head 121 sprays water, it rotates relative to the liquid storage tank 11, and the water sprayed from the water outlet hole 1211a is sprayed outward under the action of centrifugal force, so that the brush can be stained with the cleaning liquid, thereby better cleaning the target surface. Moreover, since the suction cup 142 is adsorbed on the target surface to form a ring in contact with each other, and the mounting plate 141 is arranged around the spray structure 12, the cleaning liquid sprayed from the water outlet 1211a can be trapped in the ring-shaped mounting plate 141, and the cleaning liquid is not easy to leak out, and the dirt on the target surface (such as fruit pulp, bird excrement, etc. on the car) can be soaked while cleaning, thereby achieving a better cleaning effect. Moreover, the portable cleaning device 10 of the present application can be carried with the car, and there is no need to use manual brushing for cleaning during cleaning, which is more convenient to use.
