Description

A portable cleaning device Technical Field

[0001] This application relates to the field of cleaning equipment technology, and more specifically, to a portable cleaning device. Background Technology

[0002] Cars are common modes of transportation, and sometimes they are parked under trees. However, fallen fruit can leave berry stains on the car. Other factors can also cause stubborn dirt to accumulate, such as bird droppings. The uric acid in bird droppings is corrosive and can damage the paint. Current methods typically involve manual cleaning of these small stains or dirt, such as using a damp towel or a soft-bristled brush. However, these methods require manual effort and are quite laborious. Summary of the Invention

[0003] This application provides a portable cleaning device that can effectively clean without the need for manual cleaning.

[0004] This application is implemented as follows:

[0005] This application provides a portable cleaning device, comprising:

[0006] A liquid reservoir having a storage chamber for holding cleaning fluid;

[0007] A spraying structure is connected to the bottom of the liquid reservoir. The spraying structure includes a spray head that can rotate relative to the liquid reservoir when spraying water. The spray head includes a water outlet area and a bristle area, which are arranged alternately along the radial direction of the spray head. The water outlet area has an array of water outlet holes that can communicate with the liquid reservoir. The bristle area is provided with bristles.

[0008] A first control valve, installed at the outlet of the liquid storage chamber, is used to open or close the outlet; and

[0009] The mounting mechanism includes a mounting plate and multiple suction cups located at the bottom of the mounting plate. The mounting plate is connected to the liquid reservoir and is arranged around the spraying structure. When the multiple suction cups adhere to the target surface, they can form a ring that contacts each other, and the bristles can contact the target surface. The mounting plate has an airflow channel inside, which communicates with the suction cups. The mounting plate also has a switch structure for connecting or closing the airflow channel to the outside.

[0010] In one possible implementation, the spraying structure includes a connecting pipe and the spray head, the connecting pipe being rotatably connected to the bottom of the reservoir such that the spray head can rotate relative to the reservoir, the connecting pipe having a liquid flow channel communicating with the reservoir chamber and the water outlet of the spray head; the portable cleaning device further includes a drive mechanism configured to drive the connecting pipe to rotate.

[0011] In one possible implementation, a first bevel gear is fixedly mounted on the outer wall of the connecting pipe, the driving mechanism includes a driving member and a second bevel gear connected to the power output end of the driving member, the first bevel gear and the second bevel gear are capable of meshing, the rotation axes of the second bevel gear and the second bevel gear are perpendicular, and the driving member is mounted on the outer wall of the mounting plate.

[0012] In one possible implementation, the bottom of the reservoir has an outlet pipe, which is connected to the connecting pipe via a sealed rotary bearing.

[0013] In one possible implementation, the driving element is a motor.

[0014] In one possible implementation, the spray head is a rotary spray head connected to the reservoir.

[0015] In one possible implementation, the switch structure includes a pressing component and a spring. The outer wall of the mounting plate has a mounting hole communicating with the airflow channel. The pressing component includes a pressing element and a connecting element. The spring is sleeved on the connecting element, and one end of the spring is connected to the inner wall of the airflow channel. The other end of the spring abuts against the pressing element. The pressing element includes a pressing block and a holding block. The pressing block is disposed in the mounting hole. The holding block can abut against the side of the mounting plate facing the airflow channel under the elastic force of the spring. When the pressing block is pressed so that the holding block moves away from the side of the mounting plate facing the airflow channel, a gap can be formed between the pressing block and the wall of the mounting hole near the airflow channel.

[0016] In one possible implementation, the end of the pressing block near the outer wall of the mounting plate is a first end, and the end of the pressing block near the airflow channel is a second end. The outer diameter of the second end is larger than the inner diameter of the first end, and the outer diameter of the first end is smaller than the inner diameter of the mounting hole.

[0017] In one possible implementation, the outer diameter of the pressing block is smaller than the inner diameter of the mounting hole.

[0018] In one possible implementation, the liquid storage chamber includes a first liquid storage chamber for holding water and a second liquid storage chamber for holding cleaning agent. The outlets of the first liquid storage chamber and the second liquid storage chamber are connected by a communication channel. The outlet of the first liquid storage chamber is provided with a second control valve, and the outlet of the second liquid storage chamber is provided with a third control valve. The first control valve is located in the communication channel. The portable cleaning device also includes a controller, which is signal-connected to the first control valve, the second control valve, and the third control valve.

[0019] This application has at least the following beneficial effects:

[0020] The portable cleaning device of this application allows for the storage of cleaning fluid in the reservoir. Multiple suction cups on the bottom of the mounting plate secure the device to the target surface through suction. The water outlet and brush areas of the spray head are arranged alternately radially, with the water outlets communicating with the reservoir. When the spray head rotates relative to the reservoir, the water sprayed from the outlets is propelled outwards by centrifugal force, allowing the brushes to pick up cleaning fluid for better cleaning of the target surface. Furthermore, because the suction cups form a ring of contact with each other on the target surface, and the mounting plate surrounds the spray structure, the cleaning fluid sprayed from the outlets is trapped within the ring, preventing leakage. This allows for simultaneous cleaning and soaking of dirt (such as fruit pulp or bird droppings from a vehicle) on the target surface, achieving a superior cleaning effect. After cleaning, the airflow channel can be opened to the outside atmosphere via a switch, making it easy to remove the suction cups. Moreover, the portable cleaning device of this application can be carried in the vehicle and does not require manual scrubbing during cleaning, making it more convenient to use.

[0035] Example

[0036] This application provides a portable cleaning device 10, as shown in Figure 1, which includes a liquid reservoir 11, a spraying structure 12, and a mounting mechanism 14.

[0037] The reservoir 11 has a reservoir chamber 111 for holding cleaning fluid. The top of the reservoir 11 has an inlet, and a rotating cap 114 is detachably installed on the inlet. The rotating cap 114 is threadedly connected to the reservoir 11, allowing the inlet to be closed. In use, the rotating cap 114 is unscrewed to fill the reservoir chamber 111 with cleaning fluid. A first control valve is installed at the outlet of the reservoir chamber 111, which controls the opening or closing of the outlet. Optionally, the reservoir 11 has dimensions of 5~10cm * 5~10cm * 5~10cm.

[0038] 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 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 located in the connecting channel 1113. The portable cleaning device 10 also includes a controller, which 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, second, and third control valves, thereby controlling the flow of water and cleaning agent. When only water needs to be released from the first storage chamber 1111, the controller opens the second and first control valves and closes the third control valve. When water from the first storage chamber 1111 and cleaning agent from the second storage chamber 1112 need to be released to mix and form a cleaning solution, the controller opens the first, second, and third control valves. Optionally, a control switch is also included. The control switch is communicatively connected to the controller, for example, via electrical connection, Bluetooth connection, or Wi-Fi connection. The control switch can operate the controller to control the closing of the first, second, and third control valves. The control switch can be a mechanical switch or a touch screen switch, etc.

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

[0041] The mounting mechanism 14 includes a mounting plate 141 and multiple suction cups 142 located at the bottom of the mounting plate 141. The mounting plate 141 is connected to the liquid reservoir 11 and is arranged around the spraying structure 12. When the multiple suction cups 142 adhere to the target surface, they can form a ring that contacts each other, and the bristles 1212a can contact the target surface (see Figures 1 and 3). Optionally, the height of the mounting plate 141 is 5-10 cm, and the thickness is 1-3 cm. The mounting plate 141 has an airflow channel 1411 inside, which communicates with the suction cups 142. The mounting plate 141 also has a switch structure 16 that can be used to connect or close the airflow channel 1411 to the outside (see Figures 4-7). By controlling the switch structure 16, the airflow channel 1411 can be connected to the outside. When the suction cups 142 adhere to the target surface and need to be released, the airflow channel 1411 can be connected to the outside through the switch structure 16. When air enters, the suction cups 142 can be easily removed. 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 this application can be used by filling the first liquid storage chamber 1111 with water and the second liquid storage chamber 1112 with cleaning agent, and then closing the rotating cover 114. The controller can control the opening and closing of the first, second, and third control valves to release water and / or cleaning agent. Since the bottom of the mounting plate 141 has multiple suction cups 142, the cleaning device can be fixed to the target surface by the suction effect of the suction cups 142. Furthermore, the water outlet area 1211 and the bristle area 1212 of the spray head 121 are arranged alternately along the radial direction of the spray head 121. The water outlet hole 1211a can communicate with 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, allowing the brush to be coated with cleaning agent, thereby better cleaning the target surface. Furthermore, since the suction cup 142 adheres to the target surface and forms a ring of contact, and the mounting plate 141 is arranged around the spraying structure 12, the cleaning fluid sprayed from the water outlet 1211a can be trapped within the ring-shaped mounting plate 141, preventing leakage. This allows for simultaneous cleaning and soaking of dirt (such as fruit pulp or bird droppings on a car) on the target surface, achieving a better cleaning effect. After cleaning, the airflow channel 1411 can be connected to the outside atmosphere via the switch structure 16, making it easier to remove the suction cup 142. Moreover, the portable cleaning device 10 of this application can be carried in a vehicle and does not require manual scrubbing during cleaning, making it 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 car surfaces, floors, or walls.

[0043] The spray head 121 can be a rotating spray head 121, which is connected to the reservoir 11. The spray head 121 can rotate relative to the reservoir 11 when spraying water. In another embodiment, the spraying structure 12 includes a connecting pipe 122 and a spray head 121. The connecting pipe 122 is rotatably connected to the bottom of the reservoir 11, allowing the spray head 121 to rotate relative to the reservoir 11. Exemplarily, the bottom of the reservoir 11 has an outlet pipe 112, which is connected to the connecting pipe 122 via a sealed rotating bearing 113. The connecting pipe 122 has a liquid flow channel that connects the reservoir 111 and the water outlet 1211a of the spray head 121. The portable cleaning device 10 also includes a drive mechanism 15 configured to drive the connecting pipe 122 to rotate. The drive mechanism 15 drives the connecting pipe 122 to rotate, thereby causing the spray head 121 to rotate relative to the bottom of the liquid storage chamber 111. The water sprayed from the water outlet 1211a is sprayed outward under the action of centrifugal force, so that the brush can be covered with cleaning liquid, thereby cleaning the target surface better.

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

[0045] Furthermore, in some embodiments, the switch structure 16 includes a pressing member 161 and a spring 162, and the outer wall of the mounting plate 141 is provided with a mounting hole 1412 communicating with the airflow channel 1411. Optionally, the mounting hole 1412 is provided corresponding to the main channel. The pressing component 161 includes a pressing member 1611 and a connecting member 1612 connected together. A spring 162 is sleeved on the connecting member 1612, and one end of the spring 162 is connected to the inner wall of the airflow channel 1411. The other end of the spring 162 abuts against the pressing member 1611. The pressing member 1611 includes a pressing block 16111 and a holding block 16112. The pressing block 16111 is provided in the mounting hole 1412. The holding block 16112 can abut against the side of the mounting plate 141 facing the airflow channel 1411 under the elastic force of the spring 162. When the pressing block 16111 is pressed so that the holding block 16112 is away from the outer wall of the mounting plate 141, a gap can be formed between the pressing block 16111 and the wall of the mounting hole 1412 near the airflow channel 1411.

[0046] When the pressing block 16111 is pressed, causing the holding block 16112 to move away from the outer wall of the mounting plate 141, a gap is formed between the pressing block 16111 and the wall of the mounting hole 1412 near the airflow channel 1411. This gap allows outside air to enter the airflow channel 1411, making it easier to remove the suction cup 142. When the pressing block 16111 is released, the spring 162 causes the holding block 16112 to press against the side of the mounting plate 141 facing the airflow channel 1411, thus cutting off the outside airflow from the airflow channel 1411.

[0047] In one embodiment, the end of the pressing block 16111 near the outer wall of the mounting plate 141 is designated as the first end 163, and the end of the pressing block 16111 near the airflow channel 1411 is designated as the second end 164. The outer diameter of the second end 164 is larger 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 wall of the mounting hole 1412 near the airflow channel 1411 (see Figures 4 and 5). In other embodiments, the outer diameter of the pressing block 16111 is smaller than the inner diameter of the mounting hole 1412 (see Figures 6 and 7), so only a short pressing distance is needed to form a gap between the pressing block 16111 and the wall of the mounting hole 1412 near the airflow channel 1411.

[0048] In summary, the portable cleaning device 10 of this application can be filled with cleaning fluid in the storage chamber 111 during use. Since the bottom of the mounting plate 141 has multiple suction cups 142, the cleaning device can be fixed to the target surface by the adsorption of the suction cups 142. In addition, the water outlet area 1211 and the bristle area 1212 of the spray head 121 are arranged alternately along the radial direction of the spray head 121. The water outlet hole 1211a can communicate with the storage chamber 111. When the spray head 121 sprays water, it rotates relative to the 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 covered with cleaning fluid, thereby cleaning the target surface better. Furthermore, since the suction cup 142 adheres to the target surface to form a ring that contacts each other, and the mounting plate 141 is arranged around the spraying structure 12, the cleaning fluid sprayed from the water outlet 1211a can be trapped inside the ring-shaped mounting plate 141, preventing the cleaning fluid from leaking out. This allows for the simultaneous cleaning and soaking of dirt (such as fruit pulp or bird droppings on a vehicle) on the target surface, thereby achieving a better cleaning effect. Moreover, the portable cleaning device 10 of this application can be carried in the vehicle and does not require manual scrubbing during cleaning, making it more convenient to use.

[0049] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
