Description

Technical Field

[0001] This application relates to the field of cleaning technology, and in particular to a cleaning device and a floor scrubber. Background Technology

[0002] In related technologies, floor scrubbers only remove water stains from the floor using squeegees during the cleaning process, but the cleaning effect still does not meet user needs. A layer of water remains on the floor after this process, making it difficult to dry quickly. Utility Model Content

[0003] Therefore, it is necessary to provide a cleaning device and floor scrubber to address the problem of poor water stain removal effect of floor scrubbers.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] In a first aspect, embodiments of this application provide a cleaning device for cleaning floors, the cleaning device comprising:

[0006] case;

[0007] A first cleaning component is mounted on the housing and includes a first scraper blade that can be controlled to contact or move away from the ground;

[0008] A drying assembly is installed inside the housing and includes a drying air pump and an air chamber. The drying air pump is connected to the air chamber pipe. The air chamber is located on one side of the first scraper and has a drying port facing the ground.

[0009] With the above design, the first scraper and the drying component start synchronously to dry the residual water stains on the ground, improving the cleaning effect and user experience.

[0010] In one embodiment of the first aspect, the cleaning device further includes a second cleaning component comprising a roller brush rotatably mounted to one end of the housing and having at least a portion of its surface exposed to the side of the housing near the ground, wherein the first scraper and the air chamber are mounted on the same side of the roller brush.

[0011] With the above design, the roller brush can rotate during movement to roll up the garbage on the ground.

[0012] In one embodiment of the first aspect, the second cleaning component further includes a second scraper, which is mounted on the side of the housing near the ground and located on the side of the roller brush opposite to the first scraper.

[0013] With the above design, when the cleaning device moves forward, the second scraper located at the rear end of the roller brush cleans up the water stains, leaving only a shallow water film on the ground, which is convenient for subsequent air drying.

[0014] In one embodiment of the first aspect, the first cleaning component further includes a drive mechanism mounted on the housing and having an output end connected to the first scraper to drive the first scraper to contact or separate from the ground.

[0015] Through the above design, the first scraper can automatically extend and retract, and the corresponding operating mode can be selected according to the requirements.

[0016] In one embodiment of the first aspect, the drive mechanism includes a drive air pump, an air intake pipe, an airbag, an exhaust pipe, and an exhaust valve. The drive air pump is connected to the airbag through the air intake pipe, the exhaust valve is connected to the airbag through the exhaust pipe, and the side of the airbag closest to the ground is connected to the first scraper.

[0017] Through the above design, the airbag can automatically inflate or deflate, thereby automatically adjusting the height of the first scraper and realizing the adjustment of the working mode of the cleaning device.

[0018] In one embodiment of the first aspect, the first cleaning component further includes a limiting mechanism, the limiting mechanism including a limiting groove, a reset member and an elastic member, the reset member being slidably disposed in the limiting groove and having its two ends respectively connected to the airbag and the first scraper, one end of the elastic member being fixed to the limiting groove and the other end being connected to the reset member.

[0019] With the above design, the elastic element is in a pressure-free state and resets under the drive of elastic potential energy, thereby applying upward pressure to the reset element and driving the reset element and the first scraper to rise back to the initial position.

[0020] In one embodiment of the first aspect, the elastic element is sleeved on the reset element, and one end is fixed to the wall of the limiting groove. The outer diameter of the end of the reset element connected to the airbag is larger than the outer diameter of the elastic element, and the end of the elastic element away from the limiting groove abuts against the end of the reset element connected to the airbag.

[0021] With the above design, during the downward adjustment of the first scraper, the elastic element is compressed by force, and when there is no force, the elastic element resets and drives the limiting element and the first scraper to rise.

[0022] Secondly, this application also provides a floor scrubbing machine, including the cleaning device, walking component and control component described in any of the above embodiments. The walking component is installed on the housing and can drive the floor scrubbing machine to move as a whole. The control component is electrically connected to the first cleaning component, the drying component and the walking component respectively.

[0023] The above design enables automated driving and operation mode adjustment of the floor scrubber.

[0025] The housing is equipped with a sewage pipe, the detection component is installed in the sewage pipe and detects the degree of dirt in the sewage pipe, and the control component receives the detection signal from the detection component to determine the degree of dirt on the ground and control the operating status of the first cleaning component and the drying component.

[0026] Through the above design, the control component can select the corresponding operating mode based on the dirt information of the sewage pipeline.

[0027] In one embodiment of the second aspect, the detection component includes an infrared emitter and an infrared receiver disposed opposite to each other, the drain pipe is made of a transparent material, and the infrared emitter and the infrared receiver are respectively disposed on two opposite sides of the drain pipe.

[0028] Through the above design, the dirt level of the sewage pipe can be automatically determined by receiving and transmitting infrared signals.

[0029] Thirdly, this application also provides a cleaning method using the floor scrubber described in any of the above embodiments, the cleaning method comprising:

[0030] Control the floor scrubber to move along the side where the first squeegee is located, and control the first squeegee to separate from the ground;

[0031] The roller brush rolls up the waste to be cleaned, and the drying component is controlled to not operate; or

[0032] Control the floor scrubber to move in a direction away from the first squeegee, and control the first squeegee to contact the ground;

[0033] Control the operation of the drying component to dry the water stains remaining on the ground from the first scraper.

[0034] The above design effectively achieves the cleaning of ground debris and residual water stains.

[0035] In one embodiment of the third aspect, the cleaning method further includes:

[0036] The system acquires signals from the detection components to determine if the sewage pipe is dirty.

[0037] The drying component and the first cleaning component are controlled to stop operating, and the first scraper cannot contact the ground;

[0038] The floor scrubber is moved under control, and the second cleaning component cleans the floor until it is determined that the drain pipe is no longer dirty.

[0039] The drying component and the first cleaning component are controlled to operate adaptively, and the first scraper can contact the ground.

[0040] The above design prevents the ground from getting too dirty and soiling the first scraper, reducing subsequent maintenance time and extending the service life of the equipment.

The cleaning device includes a housing, a first cleaning component, and a drying component. The first cleaning component includes a first scraper located at the bottom of the housing, and the drying component includes a drying air pump and a drying vent located at the bottom of the housing. Thus, during the operation of the cleaning device, the first scraper contacts the floor to initially scrape away the water stains, while the drying component simultaneously activates to dry any remaining water stains on the floor, improving the floor cleaning effect and user experience.

[0061] See Figure 1 and Figure 2 As shown, embodiments of this application provide a cleaning device for cleaning floors and effectively reducing residual water stains. For ease of understanding, the cleaning equipment provided in this application embodiment can be illustrated using a floor scrubber 100 as an example.

[0062] Specifically, the floor scrubber 100 includes a housing 110, a first cleaning component 120, and a drying component 130. Both the first cleaning component 120 and the drying component 130 are mounted on the housing 110 and can move along with the housing 110 as a whole. The first cleaning component 120 can initially remove water stains from the floor, but it will still leave a shallow water film on the floor, making rapid drying impossible. The drying component 130 can operate synchronously with the first cleaning component 120 to dry the residual water film on the floor after the cleaning component has performed its initial cleaning, thus improving the user experience.

[0063] In some embodiments, the first cleaning component 120 includes a first squeegee 121, which can be controlled to contact or move away from the ground. Thus, during operation, the floor scrubber 100 can adjust the first squeegee 121 according to the operational needs. When the floor needs to be mopped dry, the first squeegee 121 is extended to contact the ground, and the entire floor scrubber 100 is moved, allowing the first squeegee 121 in contact with the ground to scrape away water stains.

[0064] It should be noted that, for ease of understanding, the orientations in the embodiments of this application are explained. In this application, the end of the floor scrubber 100 with the first scraper 121 is called "front", the end of the floor scrubber 100 facing away from the first scraper 121 is called "rear", the direction above in the direction of gravity is called "up" and "top", and the direction below in the direction of gravity is called "down" and "bottom".

[0065] Furthermore, the first cleaning component 120 also includes a drive mechanism, which is mounted on the housing 110 and its output end is connected to the first scraper 121 to drive the first scraper 121 to contact or separate from the ground.

[0066] For example, the drive mechanism can be a hydraulic drive, pneumatic drive, linkage drive, motor drive, etc., so as to control the working state of the first scraper 121 under the action of electronic control and realize the automated operation of the floor scrubber 100.

[0067] In some embodiments, the drive mechanism includes a drive air pump 122, an air inlet pipe 123, an airbag 124, an exhaust pipe 125, and an exhaust valve 126. The drive air pump 122 is connected to the airbag 124 via the air inlet pipe 123, the exhaust valve 126 is connected to the airbag 124 via the exhaust pipe 125, and the side of the airbag 124 closest to the ground is connected to the first scraper 121.

[0068] Specifically, the drive mechanism is pneumatically driven. A drive air pump 122 is installed inside the housing 110 and connected to one end of the air intake pipe 123 to deliver airflow to the air intake pipe 123. The end of the air intake pipe 123 away from the drive air pump 122 is connected to the airbag 124 to deliver the airflow from the drive air pump 122 to the airbag 124. Upon receiving the airflow, the airbag 124 inflates, thereby pressing the first scraper 121 installed at the bottom of the airbag 124 towards the ground, causing the first scraper 121 to contact the ground. One end of the exhaust pipe 125 is connected to the airbag 124, and the other end is connected to the exhaust valve 126. The exhaust valve 126 remains closed when energized and remains open when de-energized. Thus, when the first scraper 121 is not required to operate, the drive air pump 122 is de-energized and stops supplying air, the exhaust valve 126 is de-energized and opens, the gas inside the inflated airbag 124 is discharged through the exhaust pipe 125 and the exhaust valve 126, the airbag 124 contracts and reverses the first scraper 121 to reset, thereby separating the first scraper 121 from the ground.

[0069] Continue reading Figure 3 , Figure 4 and Figure 5 As shown, the first cleaning component 120 further includes a limiting mechanism, which includes a limiting groove 128, a reset member 127 and an elastic member 129. The reset member 127 slides through the limiting groove 128 and its two ends are respectively connected to the airbag 124 and the first scraper 121. One end of the elastic member 129 is fixed to the limiting groove 128 and the other end is connected to the reset member 127.

[0070] Specifically, the limiting groove 128 has an elongated structure to accommodate the installation of the first scraper 121. The opening of the limiting groove 128 faces upward so that the elastic element 129 can be installed in the groove. The bottom end of the reset element 127 is provided with a slot to install the first scraper 121 into the slot of the reset element 127, facilitating the installation and removal of the first scraper 121. Preferably, in order to ensure the stable installation of the first scraper 121, multiple reset elements 127 should be provided, such as two ends, three, four, etc., to clamp multiple parts of the first scraper 121 and ensure the stability of the first scraper 121 during operation.

[0071] The elastic element 129 is a compression spring, and the main body of the reset element 127 is a cylindrical structure. The elastic element 129 is sleeved on the cylindrical structure of the reset element 127, with one end fixed to the bottom surface of the limiting groove 128. The end of the reset element 127 connected to the airbag 124 has a limiting end larger than the outer diameter of the spring, and the end of the elastic element 129 away from the limiting groove 128 contacts the limiting end of the reset element 127. Thus, during the downward adjustment of the first scraper 121, the drive air pump 122 is activated, the airbag 124 is inflated, and the reset element 127 moves the first scraper 121 downward until it contacts the bottom surface. During this process, the limiting end of the reset element 127 applies pressure to the elastic element 129, compressing the elastic element 129 within the limiting groove 128. During the upward adjustment of the first scraper 121, the drive air pump 122 is turned off, the airbag 124 is deflated through the exhaust pipe 125 and the exhaust valve 126, the elastic element 129 is in a pressureless state, and resets under the drive of elastic potential energy, thereby applying upward pressure to the limiting end of the reset element 127, driving the reset element 127 and the first scraper 121 to rise back to the initial position.

[0072] Continue reading Figure 6 and Figure 7 As shown, the drying assembly 130 includes a drying air pump 132 and an air chamber 131. The drying air pump 132 is connected to the air chamber 131 by a pipe. The air chamber 131 is located on one side of the first scraper 121 and has a drying port 1311 facing the ground.

[0073] Specifically, when powered on, the air-drying pump 132 delivers drying airflow to the air chamber 131 via a pipeline and blows dry air onto the bottom surface through the drying port 1311. The air chamber 131 is installed at the front end of the first scraper 121, so that when the floor scrubber 100 rotates backward, the first scraper 121 lowers to contact the bottom surface for initial removal of water stains. However, a small amount of water film may still remain on the ground. Therefore, with the synchronous start of the air-drying pump 132, the remaining water film on the bottom surface is dried by the dry air blown out by the drying port 1311 at the front end of the first scraper 121, achieving rapid drying of the bottom surface and improving the user experience.

[0074] In some embodiments, the cleaning device further includes a second cleaning assembly 140, which includes a roller brush 141 rotatably mounted on one end of the housing 110 and at least a portion of its surface exposed on the side of the housing 110 near the ground. A first scraper 121 and an air chamber 131 are mounted on the same side of the roller brush 141.

[0075] Specifically, the roller brush 141 is installed behind the second scraper 142 and can rotate along with the floor scrubber 100 during its movement. The roller brush 141 contacts the ground to collect debris during movement. Understandably, the floor scrubber 100 has an internal air duct and fan to draw the collected debris into a collection container via the air duct, thus cleaning the ground. Therefore, the floor scrubber 100 can clean the ground using the roller brush 141 during forward movement. To prevent debris from being blocked by the first scraper 121, the first scraper 121 is kept separate from the ground by the elastic element 129 when the floor scrubber 100 stops moving forward. During the movement of the floor scrubber 100, the debris contacts the roller brush 141 through the gap between the first scraper 121 and the ground and is collected by the roller brush 141. As the floor scrubber 100 moves backward, the friction between the roller brush 141 and the ground generates a large amount of water stains. At this time, the drive air pump 122 can be activated to lower the first scraper 121 into contact with the ground, so that the water stains on the ground can be initially scraped away simultaneously during the operation of the roller brush 141. In addition, the drying air pump 132 is activated simultaneously to further dry the ground after it has been treated by the first scraper 121, keeping the ground dry.

[0076] Furthermore, the second cleaning assembly 140 also includes a second scraper 142, which is mounted on the side of the housing 110 near the ground and located on the side of the roller brush 141 facing away from the first scraper 121.

[0077] Specifically, when the floor scrubber 100 moves forward, the front roller brush 141 rolls up the debris and rubs against the ground, leaving water stains on the surface. Then, the second scraper 142 at the rear of the roller brush 141 cleans up the water stains, leaving only a shallow film of water on the ground for subsequent drying.

[0078] In some embodiments, the floor scrubber 100 further includes a walking assembly 150 and a control assembly. The walking assembly 150 is mounted on the housing 110 and can drive the floor scrubber 100 to move as a whole. The control assembly is electrically connected to the first cleaning assembly 120, the drying assembly 130 and the walking assembly 150 respectively.

[0079] Understandably, the control component may include a processing chip and several operation buttons, and will determine the received signals and issue control commands through an internal running program. The walking component 150 includes a set of walking wheels and a drive motor. The control component is electrically connected to the drive motor to obtain the rotation direction of the drive motor, thereby determining the movement direction of the floor scrubber 100, and adjusting the operating mode of the first cleaning component 120 and the drying component 130 according to the movement direction of the floor scrubber 100.

[0080] Furthermore, the floor scrubber 100 also includes a detection component, which is electrically connected to the control component. A drain pipe 111 is provided inside the housing 110, and the detection component is located in the drain pipe 111 to detect the degree of dirt in the drain pipe 111.

[0081] Specifically, the sewage pipe 111 connects the internal air duct of the housing 110 to the sewage tank, so that the garbage collected by the roller brush 141 is transported to the sewage tank under the drive of the blower. Thus, the current dirt level of the ground can be judged according to the dirt level of the sewage pipe 111. When the ground is too dirty, the control component will limit the start of the drive air pump 122 to prevent the first scraper 121 from contacting the ground, which would cause the first scraper 121 to get dirty, reduce the frequency of later replacement, and extend its service life.

[0082] For example, the detection component includes an infrared emitter and an infrared receiver positioned opposite each other. The drain pipe 111 is made of transparent material, and the infrared emitter and receiver are respectively positioned on opposite sides of the drain pipe 111. Thus, during the operation of the floor scrubber 100, the drain pipe 111 carries wastewater after cleaning, and the turbidity of the wastewater effectively reflects the current cleanliness of the floor. Therefore, when the floor is relatively clean, the wastewater in the drain pipe 111 has low turbidity, and the infrared light emitted by the infrared emitter can effectively penetrate the drain pipe 111 and be received by the oppositely positioned infrared receiver. After the control component obtains the received signal from the infrared receiver, it determines that the current floor cleanliness is not dirty. However, when the floor is not clean or has stubborn stains, the wastewater in the drain pipe 111 has high turbidity, and the infrared light emitted by the infrared emitter cannot effectively penetrate the drain pipe 111. The oppositely positioned infrared receiver cannot receive the infrared light signal, and after the control component obtains the unreceived signal from the infrared receiver, it determines that the current floor cleanliness is dirty. Thus, the control component will control the descent of the first scraper 121 to prevent it from getting dirty. When the detection component detects that the drain pipe 111 is not dirty, the drive air pump 122 can operate normally and control the descent of the first scraper 121 to clean the residual water stains on the ground.

[0083] Embodiments of this application also provide a cleaning method using the floor scrubber 100 in any of the above embodiments.

[0084] Continue reading Figure 8 As shown, in some embodiments, the cleaning method includes:

[0085] S101, the control component determines that the sewage pipe 111 is not dirty according to the signal from the detection component, and drives the air pump 122 and the air drying pump 132 to operate normally.

[0086] S201, the floor scrubber 100 moves to the front, the drive air pump 122 and the drying air pump 132 stop, the first scraper 121 is controlled to separate from the ground, and the roller brush 141 cleans up the debris.

[0087] Specifically, the garbage to be cleaned can be rolled up by the roller brush 141 through the gap between the first scraper 121 and the ground, and the second scraper 142 follows to clean the water stains left on the ground by the roller brush 141, so as to achieve normal cleaning of the garbage on the ground without the garbage being blocked by the first scraper 121.

[0088] Continue reading Figure 9 As shown, in some other embodiments, the cleaning method further includes:

[0089] S101, the control component determines that the sewage pipe 111 is not dirty according to the signal from the detection component, and drives the air pump 122 and the air drying pump 132 to operate normally.

[0090] S202, the floor scrubber 100 moves to the rear end, driving the air pump 122 and the drying air pump 132 to start, the roller brush 141 cleans up the debris, the first scraper 121 is controlled to contact the ground, and the drying port 1311 continuously blows out dry air.

[0091] Specifically, after cleaning up the garbage in the forward direction, the roller brush 141 can continue to rotate backward to mop the floor again. The first scraper 121 located at the front end of the roller brush 141 can effectively clean up the water stains left on the floor by the roller brush 141. At the same time, the air drying port 1311 located in front of the first scraper 121 blows out dry air to dry the floor after it has been treated by the first scraper 121, thus improving the user experience.

[0092] Continue reading Figure 10 As shown, in some other embodiments, the cleaning method further includes:

[0093] S102, the control component determines that the sewage pipe 111 is dirty based on the signal from the detection component, and drives the air pump 122 and the air drying pump 132 to stop, and the first scraper 121 is controlled to separate from the ground.

[0094] S203, the floor scrubber 100 moves back and forth, and the roller brush 141 and the second scraper 142 clean the floor multiple times until the dirt information of the drain pipe 111 is no longer dirty.

[0095] Specifically, the first squeegee 121 will not come into contact with the ground when the floor scrubber 100 moves in any direction, to avoid the ground becoming too dirty and soiling the first squeegee 121, thus reducing later maintenance time and extending the service life of the equipment. The air pump 122 and the drying air pump 132 can then operate normally under control until the ground reaches the set dirt level.

[0096] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
