Description

Technical Field

[0001] This invention relates to the field of cleaning machine technology, and more particularly to a cleaner and a cleaning method. Background Technology

[0002] Existing fabric cleaning appliances generally use a combination of brush head, recycling tube, and main unit. To determine the cleaning effect during the cleaning process and to help decide whether to continue or stop cleaning, a dirt sensor is usually installed in the recycling tube.

[0003] Currently, dirt sensors are typically installed on the side of the main unit, at the front of the wastewater tank. However, because the recovery pipe of fabric cleaning machines is relatively long, and because the brush head is in close contact with the fabric surface during cleaning, the airflow speed in the recovery pipe is greatly reduced, resulting in a slow flow of recovered water. When the brush head is in contact with the fabric for cleaning, the time from the generation of the recovered water to its arrival at the wastewater tank of the main unit can be as long as 20 to 40 seconds. Therefore, the dirt sensor installed at the front of the wastewater tank of the main unit can only detect the degree of dirt on the fabric surface after 20 to 40 seconds, which is very untimely for assisting users or the machine itself in identifying dirt and taking timely action.

[0019] Fifthly, a cleaning method is provided, the method comprising:

[0020] The first sensor detects the sewage flowing through the first end of the sewage pipe in real time and generates corresponding first detection data;

Furthermore, various modifications and changes may be made within the scope of the appended claims.

[0040] Before describing the cleaner and cleaning method in this application, the basic structure of the cleaner will be explained first, combined with... Figures 1A to 1CA cleaner 100 includes a brush head assembly 10, a main unit 20, and a tubing assembly 30, wherein one end of the tubing assembly 30 is connected to the brush head assembly 10, and the other end is connected to the main unit 20. The brush head assembly 10 includes a handle 15 connected to the tubing assembly 30 and a cleaning component 17 connected to the handle 15. The cleaning component 17 has an interface corresponding to the tubing assembly 30, allowing the user to hold the handle 15 to clean the item. The handle 15 contains a brush head motor, and the cleaning component 17 contains a brush. The brush head motor drives the brush to rotate, thus achieving the cleaning purpose. Furthermore, the handle 15 and the cleaning component 17 are detachably connected, allowing the handle 15 to be connected to different types of cleaning components 17. To house the brush head assembly 10 and prevent it from becoming contaminated, the cleaner 100 of this application also includes a protective cover 16 for the cleaning component 17.

[0041] The main unit 20 includes a sewage tank 21 and a clean water tank 22. The piping assembly 30 includes a sewage pipe, a clean water pipe, and power and communication lines.

The main unit 20 also includes a suction assembly and a water pump connected to the clean water pipe. For example, the suction assembly may include a suction motor. When the cleaner 100 is cleaning, the water pump pumps the clean water in the clean water tank 22 into the clean water pipe and then transmits it to the brush head assembly 10. The brush head assembly 10 is provided with a water outlet, and the clean water flows out through the water outlet to the surface of the item to be cleaned. The cleaning component 17 in the brush head assembly 10 starts to clean the item under the drive of the brush head motor. Wastewater is generated during the cleaning process. The brush head assembly 10 is also provided with a collection device for collecting wastewater. At this time, the suction motor generates a certain suction force to suck the wastewater from the collection device into the wastewater pipe and then discharge it into the wastewater tank 21.

[0042] In some embodiments of this application, the host 20 is further provided with a first control element, and a first sensor is provided inside the brush head assembly 10 near the first end of the sewage pipe. The first sensor can detect the sewage flowing through the first end, such as... Figure 1DAs shown, the first sensor 11 is used to analyze the contamination level of the sewage flowing through the first end of the sewage pipe 19, which is sucked up by the suction assembly, based on the light transmittance of the sewage.

The first control element calculates the light transmittance representing the transparency of the sewage at the first end of the sewage pipe 19 based on the first detection data, and determines the first degree of contamination of the sewage, and controls the working state of the brush head assembly 10 according to the first degree of contamination, wherein the working state of the brush head assembly 10 includes the brush head assembly 10 operating at a certain power or being turned off.

The power cord interface 14 includes three interfaces, which can be used to connect power supply lines or communication lines, etc. Data transmission between the first sensor 11 and the first control element can be achieved through wireless communication, which is not limited in this embodiment.

The first sensor 11 can transmit the first detection data to the first control element and the second control element, and the second sensor can transmit the second detection data to the first control element and the second control element. The first control element is the main control element, and the second control element is the auxiliary control element.

[0047] The cleaner and cleaning method of this application will now be described in conjunction with the accompanying drawings and specific embodiments.

[0048] Example 1

[0049] like Figure 2 As shown, this embodiment provides a cleaner 100, which includes a brush head assembly 10, a main unit 20, and a tubing assembly 30.

[0050] The main unit 20 includes a sewage tank 21 and a first control element 23;

[0051] Pipeline assembly 30 includes a sewage pipe, which includes a first end and a second end corresponding to the first end. The first end is connected to the brush head assembly 10, and the second end is connected to the sewage tank 21. Sewage generated during the cleaning process flows into the sewage tank 21 through the sewage pipe. A first sensor 11 is provided in the brush head assembly 10 near the first end of the sewage pipe.

[0052] The first sensor 11 is used to detect the sewage flowing through the first end in real time and generate corresponding first detection data;

[0053] The first control element 23 is used to measure the first degree of dirtiness of the sewage flowing through the first end according to the first detection data, and to control the working state of the brush head assembly 10 according to the first degree of dirtiness.

[0054] In this embodiment, the cleaner 100 includes a first control element 23 and a first sensor 11. Since the first sensor 11 is located near the first end of the sewage pipe and connected to the brush head assembly 10, the first sensor 11 can promptly sense the first detection data of the sewage generated after cleaning by the brush head assembly 10. This allows the first control element 23 to promptly determine the first degree of dirtiness of the sewage flowing through the first end. During this process, the first control element 23's determination of the first degree of dirtiness is not affected by the length of the sewage pipe, thus enabling timely control of the working state of the brush head assembly 10. This allows for timely adjustment of the working state of the main unit 20 and the brush head assembly 10. The adjustment of the working state of the brush head assembly 10 by the first control element 23 includes adjusting the power and working time of the brush head motor and controlling the on / off state of the brush head motor. For example, if the first degree of dirtiness is large, the first control element 23 controls the brush head assembly 10 to work continuously. Specifically, it controls the brush head motor of the brush head assembly 10 to work continuously and adjusts the power of the brush head motor according to the degree of dirtiness, thereby achieving the effect of cleaning the items to be cleaned in a short time.

[0055] Furthermore, the main unit 20 also includes a suction assembly connected to the sewage tank 21, which draws sewage from the sewage pipe into the sewage tank 21.

[0056] The first control element 23 is also used to control the working state of the suction assembly according to the first degree of dirtiness.

[0057] In this embodiment, the suction assembly includes a suction motor. During the cleaning process, the brush head assembly 10 generates wastewater, and a collection device for collecting the wastewater is also provided on the brush head assembly 10. At this time, the suction motor generates a certain suction force to draw the wastewater from the collection device into the wastewater pipe and then discharges it into the wastewater tank 21. The first control element 23 adjusts the working state of the suction assembly, including adjusting the power of the suction motor, adjusting the working time, and controlling the on / off state of the suction motor.

[0058] Furthermore, if the first degree of dirtiness is greater than or equal to the first degree threshold, the first control element 23 is also used to adjust the power of the brush head assembly 10 and the suction assembly according to the first degree of dirtiness.

[0059] If the first degree of dirtiness is less than the first degree threshold, the first control element 23 is also used to control the brush head assembly 10 to close and control the suction assembly to close after working for a preset time.

[0060] In this embodiment, the first degree threshold can be determined according to the required level of cleanliness. For example, if a higher level of cleanliness is required, the first degree threshold can be set to a smaller value. Furthermore, the first degree threshold can be close to 0. If the required level of cleanliness is not high, the first degree threshold can be set to a larger value.

[0061] In this embodiment, the control of the working state of the brush head assembly 10 and the suction assembly is divided into three stages:

[0062] In the first stage, which is the start-up stage, the first control element 23 controls the brush head assembly 10 to work at a first preset power and controls the suction assembly to work at a second preset power. At this time, within a short period of time, the first sensor 11 detects the first detection data of the sewage flowing through the first end of the sewage pipe in real time, and the first control element 23 determines the first degree of dirtiness based on the first detection data until the first degree of dirtiness is greater than or equal to the first degree threshold, and then enters the second stage.

[0063] The second stage is the adjustment stage. In this stage, as the cleaning process continues, more and more wastewater is generated in the initial stage. The first control element 23 increases the power of the brush head assembly 10 and the suction assembly according to the first degree of dirtiness. The power adjustment of the brush head assembly 10 and the suction assembly can be achieved by setting different levels according to the first degree of dirtiness and adjusting the power of the brush head assembly 10 and the suction assembly to the power value corresponding to that level. For example, different levels can be set above the first degree threshold. At the first level, the power of the brush head assembly 10 and the suction assembly is increased by 10% based on the first preset power and the second preset power, respectively. At the second level, the power of the brush head assembly 10 and the suction assembly is increased by 20% based on the first preset power and the second preset power, respectively. The power of the brush head assembly 10 and the suction assembly is adjusted accordingly according to the level of the first degree of dirtiness. The power adjustment of the brush head assembly 10 and the suction assembly can also be achieved by calculating the power of the brush head assembly 10 and the suction assembly according to the first degree of dirtiness and adjusting it to the power value corresponding to that level. Furthermore, as the cleaning process continues, less and less wastewater is generated. The first control element 23 reduces the power of the brush head assembly 10 and the suction assembly according to the first degree of dirtiness. The method of reducing the power of the brush head assembly 10 and the suction assembly can be the same as the method of increasing the power of the brush head assembly 10 and the suction assembly, and will not be described in detail here. When the first degree of dirtiness is less than the first degree threshold, the third stage begins.

[0064] In the third stage, which is the final stage, when the degree of dirtiness is less than the first degree threshold, it indicates that the cleaning requirement has been met. The first control element 23 controls the brush head assembly 10 to shut off. At this time, there may still be sewage in the sewage pipe. The first control element 23 controls the suction assembly to work for a preset time and then shut off, thereby sucking the sewage pipe clean. This is to avoid the sewage pipe from being blocked by impurities due to residual sewage, which may lead to the growth of bacteria and to prevent residual sewage from dripping onto the surface of the items to be cleaned when the user cleans the machine, causing contamination. In the third stage, the power of the suction assembly can be a fixed value or a variable value; this embodiment does not limit this.

[0065] Furthermore, the main unit 20 also includes a clean water tank 22 and a water pump connected to the clean water tank 22; the pipeline assembly 30 also includes a clean water pipe with one end connected to the clean water tank 22 and the other end connected to the brush head assembly 10, and the water pump delivers the clean water in the clean water tank 22 to the brush head assembly 10 through the clean water pipe.

[0066] The first control element 23 is also used to control the operating status of the water pump according to the first degree of dirtiness.

[0067] In this embodiment, the first control element 23 adjusts the working state of the water pump by adjusting the pumping volume, pumping duration, and controlling the on / off state of the water pump.

[0068] Furthermore, if the first degree of dirtiness is greater than or equal to the first degree threshold, the first control element 23 is also used to adjust the pumping volume of the water pump according to the first degree of dirtiness.

[0069] If the first level of dirtiness is less than the first level threshold, the first control element 23 is also used to control the water pump to shut down.

[0070] In this embodiment, in the first stage, the first control element 23 controls the water pump to pump water at a preset pumping volume, so that clean water flows from the clean water cylinder through the clean water pipe to the brush head assembly 10, thereby ensuring that the brush head assembly 10 has enough clean water to maintain the normal operation of the cleaning process during the opening stage.

[0071] In the second stage, which is the adjustment stage, as the cleaning process continues, the power of the brush head motor of the brush head assembly 10 increases during the initial stage, requiring more and more clean water. Therefore, the first control element 23 increases the water pump's pumping volume according to the first degree of dirtiness. Adjusting the water pump's pumping volume can be achieved by setting different levels based on the first degree of dirtiness, adjusting the pumping volume to the power value corresponding to that level. For example, different levels can be set above the first degree threshold. At the first level, the pumping volume increases by 10% based on the preset pumping volume; at the second level, the pumping volume increases by 20% based on the preset pumping volume. The adjustment of the pumping volume can also be calculated based on the first degree of dirtiness. Furthermore, as the cleaning process continues, less wastewater is generated, and the first control element 23 reduces the pumping volume according to the first degree of dirtiness. The method for reducing the pumping volume can be the same as the method for increasing the pumping volume, and will not be elaborated further here. When the level of dirtiness is less than the first level threshold, the third stage begins.

[0072] In the third stage, which is the final stage, when the first degree of dirtiness is less than the first degree threshold, it means that the cleaning requirement has been met, and the first control element 23 controls the water pump to shut down, with the pumping volume being 0.

[0073] In this embodiment, the power adjustment of the suction assembly, the power adjustment of the brush head assembly 10, and the water pumping volume adjustment can be achieved by the first control element 23 adjusting the voltage or current applied to the suction assembly, the brush head assembly 10, and the water pump. For example, the suction assembly has a first voltage regulator corresponding to the suction motor, the brush head assembly 10 has a second voltage regulator corresponding to the brush head motor, and the main unit 20 has a third voltage regulator corresponding to the water pump. In the first stage, the first control element 23 sends a first signal, a second signal, and a third signal to the first voltage regulator, the second voltage regulator, and the third voltage regulator, respectively, causing the first voltage regulator, the second voltage regulator, and the third voltage regulator to... The three voltage regulators apply a first voltage, a second voltage, and a third voltage to the suction motor, the brush head motor, and the water pump, respectively. In the second stage, as the degree of dirtiness changes, the first control element 23 sends a first adjustment signal, a second adjustment signal, and a third adjustment signal to the first voltage regulator, the second voltage regulator, and the third voltage regulator, respectively, to adjust the voltage across the suction motor, the brush head motor, and the water pump in real time. In the third stage, the first control element 23 sends a shutdown signal to the second voltage regulator and the third voltage regulator, respectively, and the voltage across the water pump and the brush head motor becomes 0. The first control element 23 then sends a fourth signal to the first voltage regulator to shut down the suction motor after it continues to work for a period of time.

[0074] Furthermore, the host 20 also includes a first interaction element, which is used to receive a first interaction command from the user and send the first interaction command to the first control element 23.

[0075] In this embodiment, after receiving the user's first interaction instruction, the first interaction element sends the first interaction instruction to the first control element 23, and the first control element 23 executes subsequent operations according to the user's first interaction instruction.

[0076] The first interactive element can take various forms of interaction, such as touch buttons, touch screens, voice interaction, or light interaction. Therefore, the first interactive element can be a button, a screen, an LED light, etc., and can take one form or a combination of forms. For example, a user can select to start cleaning by using a switch button or by using voice interaction. Alternatively, the user can select to start cleaning by using a switch button and then select the cleaning mode by using voice interaction, and the LED light will illuminate during the cleaning process to indicate that cleaning is in progress.

[0077] Furthermore, the first interactive element allows the user to clearly understand the current cleaning process. For example, in the first stage, the LED light emits green light, or the host 20 issues a voice message "Start cleaning". In the second stage, or the host 20 issues a voice message "Continuing to clean" and the LED light emits red light, in the third stage, the LED light emits yellow light, or the host 20 issues a voice message "Cleaning is about to end".

[0078] Furthermore, the first interactive instruction includes a cleaning mode selected by the user, and the first control element 23 is also used to control the working status of the brush head assembly 10, the suction assembly, and the water pump according to the cleaning mode and the first degree of dirtiness.

[0079] In this embodiment, the cleaning mode can include multiple modes. For example, it can include a normal cleaning mode and a deep cleaning mode. In the deep cleaning mode, the cleaning force is greater, the brush head assembly 10 rotates faster, the water pump draws more water, and the suction force of the suction assembly is greater, thereby achieving rapid and deep cleaning of dirt. In the normal cleaning mode, the cleaning force is less, the brush head assembly 10 rotates slower, the water pump draws less water, and the suction force of the suction assembly is less, thereby achieving cleaning of dirt with less cleaning force.

[0080] Furthermore, users can select cleaning modes in multiple ways, either directly or indirectly. For direct selection, users can input the cleaning mode through the first interactive element, such as by pressing a button, using a touch screen, or by voice input. For indirect selection, users can input the material of the item to be cleaned through the first interactive element, and then the first control element 23 will automatically select the corresponding cleaning mode based on the material of the item to be cleaned, such as by pressing a button, using a touch screen, or by voice input.

[0081] In this embodiment, the first control element 23 is also used to control the working state of the brush head assembly 10, the suction assembly and the water pump according to the cleaning mode and the first degree of dirtiness. Specifically, the first control element 23 determines the power of the brush head assembly 10, the suction assembly and the water pump in three working stages according to the cleaning mode, and determines the corresponding working time according to the first degree of dirtiness, so as to achieve a good cleaning effect.

The first end is connected to the brush head assembly 10, and the second end is connected to the sewage tank 21. Sewage generated during the cleaning process flows into the sewage tank 21 through the sewage pipe. A first sensor 11 is provided in the brush head assembly 10 near the first end of the sewage pipe.

[0086] The first sensor 11 is used to detect the sewage flowing through the first end in real time and generate corresponding first detection data;

[0087] The first control element 23 is used to measure the first degree of dirtiness of the sewage flowing through the first end according to the first detection data, and to control the working state of the brush head assembly 10 according to the first degree of dirtiness.

[0088] A second sensor 24 is installed inside the main unit 20 near the second end of the sewage pipe; the main unit 20 also includes a suction assembly connected to the sewage tank 21, which is used to pump sewage from the sewage pipe into the sewage tank 21.

[0089] The second sensor 24 is used to detect the sewage flowing through the second end in real time and generate corresponding second detection data.

[0090] The first control element 23 is also used to measure the second degree of dirtiness of the sewage flowing through the second end based on the second detection data, and to control the working state of the brush head assembly 10 based on the second degree of dirtiness.

[0091] In this embodiment, the cleaner 100 includes a first control element 23, a first sensor 11, and a second sensor 24. Since the first sensor 11 is located inside the brush head assembly 10 and near the first end of the wastewater pipe, and the second sensor 24 is located inside the main unit 20 and near the second end of the wastewater pipe, the first sensor 11 can promptly sense the first detection data of the wastewater generated after cleaning by the brush head assembly 10. This allows the first control element 23 to promptly determine the first degree of dirtiness of the wastewater flowing through the first end. The second end is connected to the wastewater tank 21, so the second sensor 24 can promptly sense the second detection data of the wastewater generated after cleaning by the brush head assembly 10. This allows the first control element 23 to promptly determine the first degree of dirtiness of the wastewater flowing through the second end. Therefore, in this embodiment, the first control element... The control of the working state of the brush head assembly 10 by component 23 is not affected by the length of the sewage pipe. On the one hand, it can control the working state of the brush head assembly 10 in a timely manner, thereby adjusting the working state of the main unit 20 and the brush head assembly 10 in a timely manner. For example, when the initial degree of dirt is large, the power of the brush head assembly 10 can be increased in time. On the other hand, it can prevent sewage residue in the sewage pipe, thereby avoiding the possibility of impurities settling in the sewage pipe, which may lead to blockage of the sewage pipe and the growth of bacteria. It can also prevent residual sewage from dripping onto the surface of the items to be cleaned when the user cleans the cleaning machine, causing pollution. For example, if the initial degree of dirt has met the requirements, but the second degree of dirt is still large due to the long length of the sewage pipe, the sewage in the sewage pipe can continue to be sucked to avoid sewage residue.

[0092] In this embodiment, the suction assembly includes a suction motor. During the cleaning process, the brush head assembly 10 generates wastewater, and a collection device for collecting the wastewater is also provided on the brush head assembly 10. At this time, the suction motor generates a certain suction force to draw the wastewater from the collection device into the wastewater pipe and then discharges it into the wastewater tank 21. The first control element 23 adjusts the working state of the suction assembly, including adjusting the power of the suction motor, adjusting the working time, and controlling the on / off state of the suction motor.

[0093] Furthermore, if the first degree of dirtiness is greater than or equal to the first degree threshold and the second degree of dirtiness is less than the first degree threshold, the first control element 23 is also used to control the brush head assembly 10 and the suction assembly to work continuously at the first preset power and the second preset power, respectively.

[0094] If both the first degree of dirtiness and the second degree of dirtiness are greater than or equal to the first degree threshold, the first control element 23 is further used to adjust the power of the brush head assembly 10 according to the first degree of dirtiness and to adjust the power of the suction assembly according to the second degree of dirtiness.

[0095] If the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is greater than or equal to the first degree threshold, the first control element 23 is also used to control the brush head assembly 10 to close and to control the suction assembly to continue working according to the second degree of dirtiness.

[0096] If the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is less than the first degree threshold, then the first control element 23 is also used to control both the brush head assembly 10 and the suction assembly to be turned off.

[0097] In this embodiment, the first degree threshold can be determined according to the required level of cleanliness. For example, if a higher level of cleanliness is required, the first degree threshold can be set to a smaller value. Furthermore, the first degree threshold can be close to 0. If the required level of cleanliness is not high, the first degree threshold can be set to a larger value.

[0098] In this embodiment, the control of the working state of the brush head assembly 10 and the suction assembly is divided into four stages:

[0099] In the first stage, the degree of dirtiness is greater than or equal to a first threshold and the degree of dirtiness is less than the first threshold. After cleaning begins, the first control element 23 controls the brush head assembly 10 to operate at a first preset power and controls the suction assembly to operate at a second preset power. At this time, within a short period of time, the first sensor 11 detects the presence of wastewater. Since the wastewater pipe has a certain length, the second sensor 24 does not detect the presence of wastewater at this time. Therefore, the degree of dirtiness is relatively high and the degree of dirtiness is relatively low. The first sensor 11 and the second sensor 24 continue to detect until the wastewater flows to the second end of the wastewater pipe, and the degree of dirtiness is greater than or equal to the first threshold, thus entering the second stage.

[0100] In the second stage, both the first degree of dirtiness and the second degree of dirtiness are greater than or equal to the threshold of the first degree. As the cleaning process continues, more and more wastewater is generated in the initial stage. The first control element 23 adjusts the power of the brush head assembly 10 according to the first degree of dirtiness, and adjusts the power of the suction assembly according to the second degree of dirtiness. The power adjustment of the brush head assembly 10 and the suction assembly can be achieved by setting different levels according to the first degree of dirtiness and adjusting the power of the brush head assembly 10 and the suction assembly to the power value corresponding to that level. For example, different levels can be set above the first degree threshold. If the first degree of dirtiness is at the first level, the power of the brush head assembly 10 is increased by 10% based on the first preset power. If the second degree of dirtiness is at the first level, the power of the suction assembly is increased by 10% based on the second preset power. If the first degree of dirtiness is at the second level, the power of the brush head assembly 10 is increased by 20% based on the first preset power. The power adjustment of the brush head assembly 10 and the suction assembly can be calculated based on the first degree of dirtiness and adjusted to the power value corresponding to that level. Furthermore, as the cleaning process continues, less and less wastewater is generated. At this point, the first level of dirtiness will decrease first. Due to the certain length of the wastewater pipe, the decrease in the second level of dirtiness will be somewhat delayed until the first level of dirtiness is less than the first level threshold and the second level of dirtiness is greater than or equal to the first level threshold, at which point the third stage begins.

[0101] In the third stage, the first level of dirtiness is less than the first threshold and the second level of dirtiness is greater than or equal to the first threshold. At this point, the brush head assembly 10 has completed cleaning the item to be cleaned, but there is still residual wastewater in the wastewater pipe. At this time, the first control element 23 also controls the brush head assembly 10 to shut down, on the one hand to prevent excessive wear on the surface of the item to be cleaned by the roller brush in the brush head assembly 10, and on the other hand to avoid unnecessary power consumption. The first control element 23 controls the suction assembly to continue working. During this process, the power of the suction assembly is still adjusted by the first control element 23 according to the second level of dirtiness; the specific adjustment method will not be elaborated here. As the amount of wastewater decreases, the second level of dirtiness will gradually decrease until the first level of dirtiness is less than the first threshold and the second level of dirtiness is less than the first threshold, entering the fourth stage.

[0102] In the fourth stage, the first control element 23 is also used to control both the brush head assembly 10 and the suction assembly to be turned off. At this time, the brush head assembly 10 has completed the cleaning work, and the suction assembly has completed the sewage suction work, and the entire cleaning process is over.

[0103] Furthermore, the main unit 20 also includes a clean water tank 22 and a water pump connected to the clean water tank 22; the pipeline assembly 30 also includes a clean water pipe with one end connected to the clean water tank 22 and the other end connected to the brush head assembly 10, and the water pump delivers the clean water in the clean water tank 22 to the brush head assembly 10 through the clean water pipe.

[0104] The first control element 23 is also used to control the operating state of the water pump according to the first degree of dirtiness and the second degree of dirtiness.

[0105] In this embodiment, the first control element 23 adjusts the working state of the water pump by adjusting the pumping volume, pumping duration, and controlling the on / off state of the water pump.

[0106] Furthermore, if the first degree of dirtiness is greater than or equal to the first degree threshold and the second degree of dirtiness is less than the first degree threshold, then the first control element 23 is also used to control the water pump to continue working at a preset pumping volume.

[0107] If both the first degree of dirtiness and the second degree of dirtiness are greater than or equal to the first degree threshold, the first control element 23 is also used to adjust the pumping volume of the water pump according to the first degree of dirtiness.

[0108] If the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is greater than or equal to the first degree threshold, then the first control element 23 is also used to control the water pump to shut down.

[0109] In this embodiment, in the first stage, the first control element 23 controls the water pump to pump water at a preset pumping volume, so that clean water flows from the clean water cylinder through the clean water pipe to the brush head assembly 10, thereby ensuring that the brush head assembly 10 has enough clean water to maintain the normal operation of the cleaning process during the opening stage.

[0110] In the second stage, as the cleaning process continues, initially the power of the brush head motor in the brush head assembly 10 increases, requiring more and more clean water. Therefore, the first control element 23 increases the water pump's pumping volume according to the first degree of dirtiness. Adjusting the pumping volume can be achieved by setting different levels based on the first degree of dirtiness, adjusting the pumping volume to the power value corresponding to that level. For example, different levels can be set above the first degree threshold. At the first level, the pumping volume increases by 10% based on the preset pumping volume; at the second level, the pumping volume increases by 20% based on the preset pumping volume. The pumping volume can also be calculated based on the first degree of dirtiness. Furthermore, as the cleaning process continues, less wastewater is generated. The first control element 23 then reduces the pumping volume according to the first degree of dirtiness. The method for reducing the pumping volume can be the same as the method for increasing the pumping volume, and will not be elaborated further here.

[0111] In the third stage, the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is greater than or equal to the first degree threshold. At this time, the cleaning work of the brush head assembly 10 has been completed. Therefore, the water pump also needs to be turned off accordingly. The first control element 23 controls the water pump to turn off, and the water pumping volume is 0.

[0112] In this embodiment, the power adjustment of the suction assembly, the power adjustment of the brush head assembly 10, and the water pump's pumping volume can be achieved by the first control element 23 adjusting the voltage or current applied to the suction assembly, the brush head assembly 10, and the water pump. For example, the suction assembly has a first voltage regulator corresponding to the suction motor, the brush head assembly 10 has a second voltage regulator corresponding to the brush head motor, and the main unit 20 has a third voltage regulator corresponding to the water pump. In the first stage, the first control element 23 sends a first signal, a second signal, and a third signal to the first voltage regulator, the second voltage regulator, and the third voltage regulator, respectively, causing the first voltage regulator, the second voltage regulator, and the third voltage regulator to respectively control the suction motor, the brush head motor, and the water pump. A first voltage, a second voltage, and a third voltage are applied to both ends of the water pump. In the second stage, as the first and second degrees of dirtiness change, the first control element 23 sends a first adjustment signal, a second adjustment signal, and a third adjustment signal to the first voltage regulator, the second voltage regulator, and the third voltage regulator, respectively, to adjust the voltages across the suction motor, the brush head motor, and the water pump in real time. In the third stage, the first control element 23 sends a shut-off signal to the second and third voltage regulators, respectively, and the voltages across the water pump and the brush head motor are 0. The first control element 23 sends a fourth adjustment signal to the first voltage regulator according to the second degree of dirtiness. In the fourth stage, the first control element 23 sends a shut-off signal to the first voltage regulator, and the voltage across the suction motor is 0.

[0113] Furthermore, the host 20 also includes a first interaction element, which is used to receive a first interaction command from the user and send the first interaction command to the first control element 23;

[0114] The brush head assembly 10 also includes a second interaction element, which is used to receive a second interaction command from the user and send the second interaction command to the first control element 23.

[0115] In this embodiment, after receiving the user's first interaction instruction, the first interaction element sends the first interaction instruction to the first control element 23, which then performs subsequent operations according to the user's instruction. After receiving the user's second interaction instruction, the second interaction element sends the second interaction instruction to the first control element 23, which then performs subsequent operations according to the user's instruction.

[0116] The interaction methods of the first and second interactive elements can be varied, including touch buttons, touch screens, voice interaction, and light interaction. Therefore, the first and second interactive elements can be buttons, screens, LED lights, etc., and can be a single form or a combination of forms. For example, a user can select to start cleaning via a power button, or via voice interaction. Alternatively, a user can select to start cleaning via a power button and then select a cleaning mode via voice interaction, with the LED light illuminating during the cleaning process to indicate that cleaning is in progress. In this embodiment, the forms of the first and second interactive elements can be the same or different. For example, both the first and second interactive elements can be buttons; the first interactive element can also be a screen and the second interactive element can be a button. This embodiment does not limit this.

[0117] Furthermore, the first or second interactive instruction includes a cleaning mode selected by the user, and the first control element 23 is also used to control the working state of the brush head assembly 10 according to the cleaning mode and the first degree of dirtiness, and to control the working state of the suction assembly and the water pump according to the cleaning mode and the second degree of dirtiness.

[0118] In this embodiment, the cleaning mode can include multiple modes. For example, it can include a normal cleaning mode and a deep cleaning mode. In the deep cleaning mode, the cleaning force is greater, the brush head assembly 10 rotates faster, the water pump draws more water, and the suction force of the suction assembly is greater, thereby achieving rapid and deep cleaning of dirt. In the normal cleaning mode, the cleaning force is less, the brush head assembly 10 rotates slower, the water pump draws less water, and the suction force of the suction assembly is less, thereby achieving cleaning of dirt with less cleaning force.

[0119] Furthermore, users can select cleaning modes in multiple ways, either directly or indirectly. For direct selection, users can input the cleaning mode through the first interactive element, such as by pressing a button, using a touch screen, or by voice input. For indirect selection, users can input the material of the item to be cleaned through the first interactive element, and then the first control element 23 will automatically select the corresponding cleaning mode based on the material of the item to be cleaned, such as by pressing a button, using a touch screen, or by voice input.

[0120] In this embodiment, the first control element 23 is also used to control the working state of the brush head assembly 10, the suction assembly and the water pump according to the cleaning mode and the second degree of dirtiness. Specifically, the first control element 23 determines the power of the brush head assembly 10, the suction assembly and the water pump in four working stages according to the cleaning mode, and determines the corresponding working time according to the first degree of dirtiness, so as to achieve a good cleaning effect.

[0121] Example 3

[0122] like Figure 4 As shown, this embodiment provides a cleaner 100, which includes a brush head assembly 10, a main unit 20, and a tubing assembly 30.

[0123] The main unit 20 includes a sewage tank 21 and a first control element 23;

[0124] Pipeline assembly 30 includes a sewage pipe, which includes a first end and a second end corresponding to the first end. The first end is connected to the brush head assembly 10, and the second end is connected to the sewage tank 21. Sewage generated during the cleaning process flows into the sewage tank 21 through the sewage pipe. A first sensor 11 is provided in the brush head assembly 10 near the first end of the sewage pipe.

[0125] The first sensor 11 is used to detect the sewage flowing through the first end in real time and generate corresponding first detection data;

[0126] A second control element 18 is provided inside the brush head assembly 10;

[0127] The first control element 23 is further configured to measure the first degree of dirtiness of the sewage flowing through the first end based on the first detection data, and send a first control command containing the first degree of dirtiness to the second control element 18. The second control element 18 is further configured to control the working state of the brush head assembly 10 according to the first degree of dirtiness after receiving the first control command. Alternatively, the first control element 23 sends a second control command to the second control element 18. The second control element 18 is further configured to measure the first degree of dirtiness of the sewage flowing through the first end based on the first detection data after receiving the second control command, and control the working state of the brush head assembly 10 according to the first degree of dirtiness.

[0128] In this embodiment, the cleaner 100 includes a first control element 23, a second control element 18, and a first sensor 11. The first sensor 11 is located inside the brush head assembly 10 near the first end of the sewage pipe. The first control element 23 is located on the main unit 20, and the second control element 18 is located on the brush head assembly 10. Unlike embodiment two, in this embodiment, the working state of the brush head assembly 10 is controlled by the second control element 18 according to the first degree of dirtiness. There are two implementation methods here. One implementation method is that the first control element 23 calculates the first degree of dirtiness and sends it to the second control element 18. Specifically, the first control element 23... The first degree of dirtiness of the sewage flowing through the first end is measured based on the first detection data, and a first control command containing the first degree of dirtiness is sent to the second control element 18. The second control element 18 is also used to control the working state of the brush head assembly 10 according to the first degree of dirtiness upon receiving the first control command. Alternatively, the second control element 18 calculates the first degree of dirtiness. Specifically, the first control element 23 sends a second control command to the second control element 18. The second control element 18 is also used to measure the first degree of dirtiness of the sewage flowing through the first end based on the first detection data after receiving the control command, and control the working state of the brush head assembly 10 according to the first degree of dirtiness.

[0129] In this embodiment, regardless of the method used, on the one hand, the first sensor 11 can promptly sense the first detection data of the wastewater generated after cleaning by the brush head assembly 10, and adjust the working state of the brush head assembly 10 in a timely manner. On the other hand, the second control element 18 is used to adjust the working state of the brush head assembly 10, which reduces the requirements on the first control element 23.

[0130] Furthermore, a second sensor is provided inside the main unit 20 near the second end of the sewage pipe. The main unit 20 also includes a suction assembly connected to the sewage tank 21, which is used to pump sewage from the sewage pipe into the sewage tank 21.

[0131] The second sensor is used to detect the sewage flowing through the second end in real time and generate corresponding second detection data;

[0132] The first control element 23 is also used to measure the second degree of dirtiness of the sewage flowing through the second end based on the second detection data, and to control the working state of the suction assembly based on the second degree of dirtiness.

[0133] In this embodiment, the suction assembly includes a suction motor. During the cleaning process, the brush head assembly 10 generates wastewater, and a collection device for collecting the wastewater is also provided on the brush head assembly 10. At this time, the suction motor generates a certain suction force to draw the wastewater from the collection device into the wastewater pipe and then discharges it into the wastewater tank 21. The first control element 23 adjusts the working state of the suction assembly, including adjusting the power of the suction motor, adjusting the working time, and controlling the on / off state of the suction motor.

[0134] Furthermore, if the first degree of dirtiness is greater than or equal to the first degree threshold and the second degree of dirtiness is less than the first degree threshold, then the first control element 23 is also used to control the suction assembly to continue working, and the second control element 18 is also used to control the brush head assembly 10 to continue working.

[0135] If both the first degree of dirtiness and the second degree of dirtiness are greater than or equal to the first degree threshold, the second control element 18 is further used to adjust the power of the brush head assembly 10 according to the first degree of dirtiness, and the first control element 23 is further used to adjust the power of the suction assembly according to the second degree of dirtiness.

[0136] If the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is greater than or equal to the first degree threshold, then the second control element 18 is also used to control the brush head assembly 10 to close, and the first control element 23 is also used to adjust the power of the suction assembly according to the second degree of dirtiness.

[0137] If the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is less than the first degree threshold, then the second control element 18 is also used to control the brush head assembly 10 to close, and the first control element 23 is also used to control the suction assembly to close.

[0138] In this embodiment, the first degree threshold can be determined according to the required level of cleanliness. For example, if a higher level of cleanliness is required, the first degree threshold can be set to a smaller value. Furthermore, the first degree threshold can be close to 0. If the required level of cleanliness is not high, the first degree threshold can be set to a larger value.

[0139] In this embodiment, the control of the working state of the brush head assembly 10 and the suction assembly is divided into four stages:

[0140] In the first stage, the degree of dirtiness is greater than or equal to a first threshold and the degree of dirtiness is less than the first threshold. After cleaning begins, the second control element 18 controls the brush head assembly 10 to operate at a first preset power, and the first control element 23 controls the suction assembly to operate at a second preset power. At this time, within a short period of time, the first sensor 11 detects the presence of wastewater. Since the wastewater pipe has a certain length, the second sensor 24 does not detect the presence of wastewater at this time. Therefore, the degree of dirtiness is relatively high and the degree of dirtiness is relatively low. The first sensor 11 and the second sensor 24 continue to detect until the wastewater flows to the second end of the wastewater pipe, and the degree of dirtiness is greater than or equal to the first threshold, thus entering the second stage.

[0141] In the second stage, both the first degree of dirtiness and the second degree of dirtiness are greater than or equal to the threshold of the first degree. As the cleaning process continues, more and more wastewater is generated in the initial stage. The second control element 18 adjusts the brush head assembly 10 according to the first degree of dirtiness, and the first control element 23 adjusts the power of the suction assembly according to the second degree of dirtiness. The power adjustment of the brush head assembly 10 and the suction assembly can be achieved by setting different levels according to the first degree of dirtiness and adjusting the power of the brush head assembly 10 and the suction assembly to the power value corresponding to that level. For example, different levels can be set above the first degree threshold. If the first degree of dirtiness is at the first level, the power of the brush head assembly 10 is increased by 10% based on the first preset power. If the second degree of dirtiness is at the first level, the power of the suction assembly is increased by 10% based on the second preset power. If the first degree of dirtiness is at the second level, the power of the brush head assembly 10 is increased by 20% based on the first preset power. The power adjustment of the brush head assembly 10 and the suction assembly can be calculated based on the first degree of dirtiness and adjusted to the power value corresponding to that level. Furthermore, as the cleaning process continues, less and less wastewater is generated. At this point, the first level of dirtiness will decrease first. Due to the certain length of the wastewater pipe, the decrease in the second level of dirtiness will be somewhat delayed until the first level of dirtiness is less than the first level threshold and the second level of dirtiness is greater than or equal to the first level threshold, at which point the third stage begins.

[0142] In the third stage, the first level of dirtiness is less than the first threshold and the second level of dirtiness is greater than or equal to the first threshold. At this point, the brush head assembly 10 has completed cleaning the item to be cleaned, but there is still residual wastewater in the wastewater pipe. At this time, the second control element 18 is also used to control the brush head assembly 10 to shut down, on the one hand to prevent excessive wear on the surface of the item to be cleaned by the roller brush in the brush head assembly 10, and on the other hand to avoid unnecessary power consumption. The first control element 23 controls the suction assembly to continue working. During this process, the power of the suction assembly is still adjusted by the first control element 23 according to the second level of dirtiness; the specific adjustment method will not be elaborated here. As the amount of wastewater decreases, the second level of dirtiness will gradually decrease until both the first level of dirtiness and the second level of dirtiness are less than the first threshold, entering the fourth stage.

[0143] In the fourth stage, the first control element 23 controls the suction assembly to close, and the second control element 18 controls the brush head assembly 10 to close. At this time, the brush head assembly 10 has completed the cleaning work, and the suction assembly has completed the sewage suction work, and the entire cleaning process is over.

[0144] Furthermore, the main unit 20 also includes a clean water tank 22 and a water pump connected to the clean water tank 22; the pipeline assembly 30 also includes a clean water pipe with one end connected to the clean water tank 22 and the other end connected to the brush head assembly 10, and the water pump delivers the clean water in the clean water tank 22 to the brush head assembly 10 through the clean water pipe.

[0145] The first control element 23 is also used to control the operating status of the water pump according to the first degree of dirtiness.

[0146] In this embodiment, the first control element 23 adjusts the working state of the water pump by adjusting the pumping volume, pumping duration, and controlling the on / off state of the water pump.

[0147] Furthermore, if the first degree of dirtiness is greater than or equal to the first degree threshold and the second degree of dirtiness is less than the first degree threshold, then the first control element 23 is also used to control the water pump to continue working at a preset pumping volume.

[0148] If both the first degree of dirtiness and the second degree of dirtiness are greater than or equal to the first degree threshold, the first control element 23 is also used to adjust the flow rate of the water pump according to the first degree of dirtiness.

[0149] If the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is greater than or equal to the first degree threshold, then the first control element 23 is also used to control the water pump to shut down.

[0150] In this embodiment, in the first stage, the first control element 23 controls the water pump to pump water at a preset pumping volume, so that clean water flows from the clean water cylinder through the clean water pipe to the brush head assembly 10, thereby ensuring that the brush head assembly 10 has enough clean water to maintain the normal operation of the cleaning process during the opening stage.

[0151] In the second stage, as the cleaning process continues, initially the power of the brush head motor in the brush head assembly 10 increases, requiring more and more clean water. Therefore, the first control element 23 increases the water pump's pumping volume according to the first degree of dirtiness. Adjusting the pumping volume can be achieved by setting different levels based on the first degree of dirtiness, adjusting the pumping volume to the power value corresponding to that level. For example, different levels can be set above the first degree threshold. At the first level, the pumping volume increases by 10% based on the preset pumping volume; at the second level, the pumping volume increases by 20% based on the preset pumping volume. The pumping volume can also be calculated based on the first degree of dirtiness. Furthermore, as the cleaning process continues, less wastewater is generated. The first control element 23 then reduces the pumping volume according to the first degree of dirtiness. The method for reducing the pumping volume can be the same as the method for increasing the pumping volume, and will not be elaborated further here.

[0152] In the third stage, the first degree of dirtiness is less than the first degree threshold and the second degree of dirtiness is greater than or equal to the first degree threshold. At this time, the cleaning work of the brush head assembly 10 has been completed. Therefore, the water pump also needs to be turned off accordingly. The first control element 23 controls the water pump to turn off, and the water pumping volume is 0.

[0153] In this embodiment, the power adjustment of the suction assembly, the power adjustment of the brush head assembly 10, and the water pumping volume adjustment can be achieved by the first control element 23 adjusting the voltage or current applied to the suction assembly and the water pump, and the second control element 18 adjusting the voltage or current applied to the brush head assembly 10. For example, a first voltage regulator is provided in the suction assembly corresponding to the suction motor, a second voltage regulator is provided in the brush head assembly 10 corresponding to the brush head motor, and a third voltage regulator is provided in the main unit 20 corresponding to the water pump. In the first stage, the first control element 23 sends a first signal and a third signal to the first voltage regulator and the third voltage regulator, respectively, and the second control element 18 sends a second signal to the second voltage regulator, causing the first voltage regulator, the second voltage regulator, and the third voltage regulator to respectively adjust the voltage or current applied to the suction motor, the brush head motor, and the water pump. In the second stage, as the first and second degrees of dirtiness change, the first control element 23 sends a first adjustment signal and a third adjustment signal to the first and third voltage regulators, respectively. The second control element 18 sends a first adjustment signal, a second adjustment signal, and a third adjustment signal to the second voltage regulator, respectively, to adjust the voltages across the suction motor, brush head motor, and water pump in real time. In the third stage, the first control element 23 sends a shutdown signal to the third voltage regulator, and the second control element 18 sends a shutdown signal to the second voltage regulator. The voltages across the water pump and brush head motor are 0. The first control element 23 sends a fourth adjustment signal to the first voltage regulator according to the second degree of dirtiness. In the fourth stage, the first control element 23 sends a shutdown signal to the first voltage regulator, and the voltage across the suction motor is 0.

[0154] Furthermore, the host 20 also includes a first interaction element, which is used to receive a first interaction command from the user and send the first interaction command to the first control element 23;

[0155] The brush head assembly 10 also includes a second interaction element, which is used to receive a second interaction command from the user and send the second interaction command to the second control element 18.

[0156] In this embodiment, after receiving the user's first interaction command, the first interaction element sends the first interaction command to the first control element 23, which then executes the subsequent operation according to the user's command. After receiving the user's second interaction command, the second interaction element sends the second interaction command to the second control element 18, which then executes the subsequent operation according to the user's command. Thus, the host 20 and the brush head assembly 10 respectively realize their respective human-computer interaction and control processes.

[0157] The interaction methods of the first and second interactive elements can be varied, including touch buttons, touch screens, voice interaction, and light interaction. Therefore, the first and second interactive elements can be buttons, screens, LED lights, etc., and can be a single form or a combination of forms. For example, a user can select to start cleaning via a power button, or via voice interaction. Alternatively, a user can select to start cleaning via a power button and then select a cleaning mode via voice interaction, with the LED light illuminating during the cleaning process to indicate that cleaning is in progress. In this embodiment, the forms of the first and second interactive elements can be the same or different. For example, both the first and second interactive elements can be buttons; the first interactive element can also be a screen and the second interactive element can be a button. This embodiment does not limit this.

[0158] Furthermore, the first interactive instruction and / or the second interactive instruction include a cleaning mode selected by the user. The second control element 18 is also used to control the working state of the brush head assembly 10 according to the cleaning mode and the first degree of dirtiness. The first control element 23 is also used to control the working state of the suction assembly and the water pump according to the cleaning mode and the second degree of dirtiness.

[0159] In this embodiment, the cleaning mode can include multiple modes. For example, it can include a normal cleaning mode and a deep cleaning mode. In the deep cleaning mode, the cleaning force is greater, the brush head assembly 10 rotates faster, the water pump draws more water, and the suction force of the suction assembly is greater, thereby achieving rapid and deep cleaning of dirt. In the normal cleaning mode, the cleaning force is less, the brush head assembly 10 rotates slower, the water pump draws less water, and the suction force of the suction assembly is less, thereby achieving cleaning of dirt with less cleaning force.

[0160] There are several ways for users to select a cleaning mode, either directly or indirectly. For direct selection, users can input the cleaning mode through the first interactive element, such as by pressing a button, using a touch screen, or by voice input. For indirect selection, users can input the material of the item to be cleaned through the first interactive element, and then the first control element 23 will automatically select the corresponding cleaning mode based on the material of the item to be cleaned, such as by pressing a button, using a touch screen, or by voice input.

[0161] Users can select the cleaning mode through the first interactive element, the second interactive element, or both. If the user inputs the cleaning mode through the first or second interactive element, that is, if the first or second interactive command contains the cleaning mode, then the first control element 23 sends the first interactive command to the second control element 18, or the second control element 18 sends the second interactive command to the first control element 23.

[0162] In this embodiment, the second control element 18 is further used to control the working state of the brush head assembly 10 according to the cleaning mode and the first degree of dirtiness, and the first control element 23 is further used to control the working state of the suction assembly and the water pump according to the cleaning mode and the second degree of dirtiness. For example, the first control element 23 determines the power of the suction assembly and the water pump in the four working stages according to the cleaning mode, and determines the corresponding working time according to the second degree of dirtiness. The second control element 18 determines the power of the brush head assembly 10 in the four working stages according to the cleaning mode, and determines the corresponding working time according to the first degree of dirtiness, thereby achieving a good cleaning effect.
