Description

Technical Field

[0002] Currently, cleaning equipment with suction capabilities often experiences dust accumulation after a period of use. When this happens, users typically choose to clean or replace the filter. Cleaning the filter is cumbersome, while replacing it increases operating costs. Some cleaning equipment has improved the filter structure, employing multi-layer filtration to reduce dust accumulation; however, multi-layer filtration systems are mechanically complex and expensive.

Detailed Implementation

[0126] To enable those skilled in the art to more clearly understand this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0127] Furthermore, reference numerals and / or reference letters may be repeated in different examples in this application. Such repetition is for simplification and clarity purposes and does not in itself indicate a relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials; however, those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0128] In related technologies, cleaning equipment with suction capabilities can experience dust particles being insufficiently filtered due to clogged, damaged, or improperly installed filters, leading to dust recirculation. Taking floor scrubbers as an example, these machines are typically equipped with HEPA filters. HEPA is a high-efficiency particulate air filter, capable of filtering out over 99% of particles larger than 0.3 microns, making it one of the most efficient air filters available. HEPA filters fine dust particles, preventing them from entering the motor and protecting it from damage. It also filters dust mites, bacteria, viruses, and other tiny harmful substances, effectively reducing air pollution in homes. In these technologies, the dust transported to the dust collection bin through the suction pipe is dry. This dry dust disperses in the bin and, under the influence of airflow, comes into contact with the HEPA filter, preventing the dust particles from entering the motor. However, after a period of time, the HEPA filter becomes clogged with dust, lint, and other dirt, resulting in dust recirculation.

[0129] Therefore, users need to clean and replace the HEPA filter regularly during daily use. This not only maintains the vacuum cleaner's suction power but also ensures the HEPA filter's filtration effectiveness. Compared to other ordinary filters, HEPA filters are more expensive, and frequent replacements will increase the user's operating costs.

[0130] Therefore, this application proposes a cleaning device, control method, and storage medium that employs a spray dust removal method, aiming to improve the dust problem to a certain extent and reduce the replacement frequency of filters such as HEPA filters. The content of this application is described below with reference to the accompanying drawings and embodiments.

[0131] Please see Figure 1 and Figure 2 According to a first aspect of this application, a cleaning device 100 is provided. This cleaning device 100 can be a floor scrubber, vacuum cleaner, sweeping robot, or other cleaning device with a suction function, sucking dust and debris from the area to be cleaned into a collection tank. The cleaning device 100 includes a main body 110, and a suction power element (not shown in the figure), a collection tank (not shown in the figure), a suction pipe 120, a liquid supply component 130, a second pipe 140, a nozzle 150, and a cleaning component 160, all installed on the main body 110. The suction power element's exhaust port is connected to the collection tank, drawing air out of the collection tank. The suction power element can be a fan. A filter covers the exhaust port to prevent particulate matter from entering the suction power element. The collection tank is connected to the suction pipe 120, allowing dust, hair, and other debris from the area to be cleaned to be sucked into the collection tank through the suction pipe 120, achieving a dry suction function.

[0132] It is understood that the sludge collection bin is the area in the cleaning device 100 where dirt is stored. The form of the sludge collection bin varies depending on the specific type of cleaning device 100. For example, if the cleaning device 100 is a robotic vacuum cleaner, the sludge collection bin can be a dustbin. Or, if the cleaning device 100 is a floor scrubber, the sludge collection bin can be a wastewater tank. In some embodiments, the sludge collection bin has a dry-wet separation function, employing a two-tiered design. Solid materials such as wads of paper and fruit peels are stored in the upper half of the sludge collection bin, while liquids are stored in the lower half. Correspondingly, the exhaust port of the suction power element is connected to the upper half of the sludge collection bin, preventing liquids from wetting the filter. This application does not improve the structure of the suction power element or the sludge collection bin; therefore, more detailed information can be found in relevant prior art disclosures, and will not be repeated here.

[0133] The liquid supply assembly 130 includes at least a liquid supply component 133, a pump 131, and a first pipeline 132 connected in sequence. The liquid supply component 133 is used to supply and store liquid. The liquid can be clean water, cleaning agent, disinfectant, floor protectant, or a mixture of the above liquids. Users can select different types of liquids according to their actual needs. Both the liquid supply component 133 and the pump 131 are installed on the main body 110 of the equipment, and the liquid storage component is connected to the inlet of the pump 131. The pump 131 pumps the liquid to the first pipeline 132, and the first pipeline 132 delivers the liquid to the cleaning component 160 to wet the cleaning component 160, thereby realizing the function of wet floor cleaning. The cleaning component 160 can be a roller brush, mop, brush, etc., and this application is not limited thereto.

[0134] Please see Figure 2 , Figure 3 and Figure 4 In this cleaning device 100, a liquid supply assembly 130, a second pipeline 140, and a nozzle 150 are sequentially connected. The second pipeline 140 can be specifically connected to the outlet of the pump 131 or to the first pipeline 132. The pump 131 is operably connected to either the first pipeline 132 or the second pipeline 140, thereby pumping liquid into either the first pipeline 132 or the second pipeline 140. The liquid entering the first pipeline 132 ultimately flows to the cleaning component 160; the liquid entering the second pipeline 140 ultimately flows to the nozzle 150. The liquid supply assembly 130 is a liquid supply assembly configured within the cleaning device 100 itself. For example, a floor scrubber with both sweeping and mopping functions has two working modes: dry vacuuming and wet scrubbing. In wet scrubbing mode, water needs to be sprayed onto the cleaning component 160 or the floor through the liquid supply assembly 130; while in dry vacuuming mode, liquid needs to be supplied to the nozzle through the liquid supply assembly 130. In other words, the nozzle 150 and the cleaning component 160 share the liquid supply assembly 130.

[0135] Please see Figure 3 and Figure 4In some embodiments, the liquid supply assembly 130 further includes a distributor 136. The pump 131 is connected to the distributor 136 via a first pipe 132 and to the nozzle 150 via a second pipe 140. The distributor 136 has a liquid outlet facing the cleaning component 160, capable of spraying liquid onto the cleaning component 160 or onto the ground below the cleaning component 160. The specific structure of the distributor 136 can be found in relevant prior art disclosures and will not be described in detail here.

[0136] Pump 131 is operably connected to either the first conduit 132 or the second conduit 140, thereby pumping liquid into either conduit 132 or the second conduit 140. In other words, pump 131 is selectively connected to either the first conduit 132 or the second conduit 140, while nozzle 150 and distributor 136 supply liquid separately. That is, when pump 131 is operating, only one of nozzle 150 or distributor 136 sprays liquid; for example, nozzle 150 operates during dry vacuuming of a floor scrubber, while distributor 136 operates during wet scrubbing.

[0137] Pump 131 can switch its outlet by reversing its direction, thus connecting to either the first pipeline 132 or the second pipeline 140; alternatively, it can switch the connected pipeline via an external three-way valve. Please refer to [link / reference]. Figure 3 and Figure 4 In some embodiments, the cleaning device 100 further includes a three-way valve 170. The inlet of the three-way valve 170 is connected to the pump 131, and the two outlets of the three-way valve 170 are respectively connected to the first pipeline 132 and the second pipeline 140. The three-way valve 170 has two operating states. In the first operating state, the inlet is connected to the first outlet, and the second outlet is closed; in the second operating state, the inlet is connected to the second outlet, and the first outlet is closed. By setting the three-way valve 170, the pump 131 can selectively pump liquid to either the nozzle 150 or the distributor 136.

[0138] In other embodiments, pump 131 can also supply liquid to nozzle 150 and water distributor simultaneously. For example, the suction port of cleaning device 100 is located in front of cleaning component 160, and the suction port is connected to suction pipe 120 to achieve dry vacuuming. During vacuuming, nozzle 150 sprays liquid into the cavity 120a of suction pipe 120. While vacuuming dry, pump 131 pumps liquid to water distributor 136, which supplies liquid to cleaning component 160. Cleaning component 160 cleans the floor, achieving wet floor cleaning. Because the suction port is in front and cleaning component 160 is behind, floating dust and debris such as hair on the floor are sucked into suction pipe 120, and cleaning component 160 only cleans stains adhering to the floor. Compared with direct wet floor cleaning, the "vacuum-then-wash" method can achieve better cleaning results.

[0139] like Figure 3 and Figure 4As shown, in some embodiments, a water injection module 137 is provided at the outlet of the liquid supply component 133. The water injection module 137 includes at least a valve and a filter element. The valve and the filter element cooperate to open or close the outlet of the liquid supply component 133, controlling the outflow of liquid from the liquid supply component 133. The water injection module 137 is connected to the inlet of the pump 131 through the inlet pipe 134. The outlet of the pump 131 is connected to the inlet of the three-way valve 170 through the outlet pipe 135. The first outlet of the three-way valve 170 is connected to the water distributor 136 through the first pipeline 132, and the second outlet of the three-way valve 170 is connected to the second pipeline 140. The structure of the water injection module 137 in this embodiment is not improved. More detailed information can be found in the relevant disclosures in the prior art, which will not be repeated here.

[0140] To facilitate liquid replenishment by the user, in some embodiments, the liquid supply component 133 can be connected to the main body 110 of the device via a detachable structure. After the liquid in the liquid supply component 133 is used up, the user can remove the entire liquid supply component 133 and refill it with new liquid through the opening of the liquid supply component 133, for example... Figure 1 In the cleaning device 100 shown, the water tank and the top cover of the device body 110 are integrated into one unit to form the liquid supply component 133. In some other embodiments, the liquid supply component 133 can also be configured as a separate structure, with the main body of the liquid supply component 133 fixedly connected to the device body 110, thereby achieving a better sealing effect. The liquid supply component 133 is provided with an openable cover, which allows for liquid replenishment. For example, if the cleaning device 100 is a floor scrubber and the liquid supply component 133 is a water tank, with the tank cover integrated into the top cover of the device body 110, water can be added to the tank by opening the cover.

[0141] The drain outlet of the suction pipe 120 is connected to the sludge collection tank. The suction outlet 120b of the suction pipe 120 can be configured to face the ground or the cleaning component 160; this application does not impose any limitations. In some embodiments, the cleaning device 100 is a floor scrubber, and the cleaning component 160 is a roller brush. The roller brush scrubs the floor by rotating at high speed, causing dust, small particles, hair, and other debris to adhere to the roller brush. Please refer to... Figure 3 and Figure 4 The suction port 120b of the suction pipe 120 faces downward and is close to the roller brush, and the garbage is sucked into the collection box by a strong airflow.

[0142] To facilitate the fixing of the second pipe 140, the second pipe 140 can be fixed to the outside of the pipe wall 121 of the suction pipe 120 using structures such as cable ties, clips, and pipe clamps 123. Figure 4As shown. The second pipe 140 can be directly spirally wound around the outside of the suction pipe 120; alternatively, the second pipe 140 can be spirally wound around the outside of the suction pipe 120 and then fixed to the outside of the pipe wall 121 of the suction pipe 120 by means of cable ties, buckles, pipe clamps 123, etc. This application does not limit the specific connection method between the second pipe 140 and the suction pipe 120.

[0143] Please see Figure 5 and Figure 6 In the cleaning equipment 100 of this application, the nozzle 150 is installed on the pipe wall 121 of the suction pipe 120, and the nozzle 151 of the nozzle 150 is connected to the cavity 120a of the suction pipe 120. The liquid supply component 130 supplies liquid to the nozzle 150 through the second pipe 140. The nozzle 150 sprays into the cavity 120a of the suction pipe 120. The dry dust and garbage sucked into the suction pipe 120 mixes with the liquid droplets sprayed by the nozzle 150 to form sewage, thereby reducing the dust content in the collection box of the cleaning equipment 100, thereby achieving the purpose of dust reduction and improving the dust situation of the cleaning equipment 100.

[0144] Since most dust particles in the suction pipe 120 mix with the atomized droplets to form wastewater, and the specific gravity of the wastewater is significantly greater than that of air, the wastewater will collect at the bottom of the collection box after entering the collection box and will not come into contact with the filter. Only a small number of dust particles, which do not mix with the atomized droplets, enter the collection box and are carried by the airflow to the filter for filtration. Therefore, by installing nozzles 150 on the suction pipe 120, the droplets sprayed by the nozzles 150 convert dry dust into wastewater, reducing the amount of dry dust particles that come into contact with the filter, effectively solving the problem of dust re-entrainment, and also preventing excessive dirt accumulation in filters such as HEPA filters, reducing the frequency of filter replacement, and making the cleaning equipment 100 easier to maintain.

[0145] It is understood that the nozzle 150 provides atomized droplets to the cavity 120a of the suction pipe 120, and an atomizing nozzle can be used to spray into the cavity 120a of the suction pipe 120. In other embodiments, the nozzle 150 can also be a conventional nozzle. By changing the pressure of the liquid entering the conventional nozzle, the form of the liquid medium sprayed by the conventional nozzle can be changed. For example, when liquid at a first pressure is introduced, the conventional nozzle sprays atomized droplets; when liquid at a second pressure is introduced, the conventional nozzle sprays a liquid flow. This application does not limit the specific selection of the nozzle 150; any nozzle capable of spraying in the prior art can be used in this application.

[0146] One end of the second pipe 140 is connected to the nozzle 150, and the other end is connected to the pump 131 or the three-way valve 170. In some embodiments, the second pipe 140 and the nozzle 150 are both encapsulated inside the main body 110 of the equipment. That is, the second pipe 140 is located between the suction pipe 120 and the housing of the main body 110 of the equipment, and the nozzle 150 is installed in the pipe wall 121 of the suction pipe 120. The second pipe 140 and the nozzle 150 are both covered by the housing of the main body 110 of the equipment and are not visible from the outside.

[0147] The nozzle 150 is installed on the pipe wall 121 of the suction pipe 120. The nozzle 150 can be specifically installed at the suction port 120b, the middle, or the outlet of the suction pipe 120. Its specific installation position can be determined based on the internal space of the entire machine, and this application does not impose any restrictions. In some embodiments, the nozzle 150 is located in the middle of the suction pipe 120. If the nozzle 150 is installed at the suction port 120b of the suction pipe 120, the liquid sprayed by the nozzle 150 can be fully mixed with the garbage along the entire garbage movement path of the suction pipe 120, improving the dust suppression effect. However, because the liquid sprayed by the nozzle 150 will disturb the airflow within the suction pipe 120, turbulence will form at the location of the nozzle 150, which is detrimental to garbage suction. If the nozzle 150 is installed at the drain outlet of the suction pipe 120, the mixing time between the liquid sprayed by the nozzle 150 and the garbage is too short, resulting in limited dust suppression. Furthermore, the liquid droplets entering the collection box may wet the HEPA filter, affecting its filtration efficiency. In contrast, placing the nozzle 150 in the middle of the suction pipe 120 reduces the impact on the suction force of the suction port 120b of the suction pipe 120 and allows the liquid sprayed by the nozzle 150 to mix thoroughly with the garbage in the latter half of the garbage's movement path, ensuring effective dust suppression.

[0148] Please see Figure 6 The diagram illustrates the assembly structure of the nozzle 150 and the suction pipe 120 in some embodiments. The nozzle 150 is obliquely mounted on the pipe wall 121 of the suction pipe 120, and the axis of the nozzle 150 is set at an angle to the axis of the suction pipe 120, so that the liquid sprayed by the nozzle 150 can fill the cavity 120a section where the nozzle 150 is located. In some embodiments, the axis of the nozzle 150 can be further set at an angle to the radial direction of the suction pipe 120, so that the liquid sprayed by the nozzle 150 has a tendency to rotate around the pipe wall 121 of the suction pipe 120, which can wash the pipe wall 121 of the suction pipe 120 to a certain extent.

[0149] In some embodiments, the nozzle 151 of the spray head 150 is oriented towards the airflow direction of the suction pipe 120. Figure 6(As indicated by the middle arrow), the liquid sprayed by the nozzle 150 flows together with the airflow inside the suction pipe 120 towards the sludge collection tank, and mixes during the flow. That is, the direction of the nozzle 151 of the nozzle 150 (… Figure 6 The direction of the nozzle 150 (as shown by the axis) has an angle of no more than 90° with the airflow direction. In some embodiments, this angle is no more than 45°, for example, it can be 15°, 20°, 25°, 30°, 35°, 40°, etc. Because the liquid sprayed by the nozzle 150 has a motion component parallel to the airflow direction of the suction pipe 120, the resulting wind resistance is relatively small. In some embodiments, the nozzle 151 of the nozzle 150 can also be set to face away from the airflow direction of the suction pipe 120. That is, the liquid sprayed by the nozzle 150 has a motion component opposite to the airflow direction of the suction pipe 120. In this case, the liquid sprayed by the nozzle 150 convects with the dust and debris in the suction pipe 120, causing severe disturbance to the airflow in the suction pipe 120. This can improve the mixing of the liquid sprayed by the nozzle 150 with the dust and debris in the suction pipe 120, improving the dust suppression effect. However, the resulting wind resistance is larger, which will affect the suction power to some extent.

[0150] Please see Figure 6 In some embodiments, the nozzle 150 is threadedly connected to the wall 121 of the suction pipe 120, and a sealing ring 122 is provided at the connection between the nozzle 150 and the wall 121 of the suction pipe 120. In other embodiments, the nozzle 150 and the suction pipe 120 can also be connected and fixed by means of adhesive bonding, interference fit, snap-fit ​​connection, etc., and this application does not impose any restrictions.

[0151] Please see Figure 7 In some embodiments, the wall 121 of the suction pipe 120 is provided with a universal joint 124, and the nozzle 150 is mounted on the universal joint 124. By setting the universal joint 124, the installation angle of the nozzle 150 relative to the suction pipe 120 can be changed. For example, when spray dust removal is required, the installation angle of the nozzle 150 can be adjusted to be tilted upward relative to the axis of the suction pipe 120 (with the airflow direction as the top); when it is necessary to rinse the inner wall of the suction pipe 120, the installation angle of the nozzle 150 can be adjusted to be tangent to the inner wall of the suction pipe 120.

[0152] In some embodiments, the user can manually adjust the installation angle of the nozzle 150. For example, an operating handle is provided on the universal joint 124, which extends outside the housing of the main body 110 of the device. The user can move the handle to the corresponding position according to the indication on the housing, thereby adjusting the installation angle of the nozzle 150.

[0153] In other embodiments, the installation angle of the nozzle 150 can also be actively adjusted by providing an angle adjustment element 180. Please refer to [link / reference]. Figure 8 The output end of the angle adjustment component is connected to at least one of the second pipe 140, the nozzle 150, and the universal joint 124, and can change the installation angle of the nozzle 150 through its own movement. For example, the angle adjustment component 180 can be a motor-driven crank-rocker mechanism, with the rocker arm of the crank-rocker mechanism connected to the universal joint 124. The crank-rocker mechanism converts the rotation angle of the motor into a change in the posture of the universal joint 124, thereby adjusting the installation angle of the nozzle 150.

[0154] Please see Figure 9 In some embodiments, the cleaning device 100 may further include a detection element 112 for detecting the type of the ground in the area to be cleaned. The type of the ground in the area to be cleaned can be determined based on the detection signal from the detection element 112. The detection element 112 can detect the light reflection signal, coefficient of friction, etc., of the ground in the area to be cleaned. Correspondingly, the detection element 112 may be a photoelectric sensor (e.g., a reflective photoelectric sensor, a diffuse reflective photoelectric sensor, etc.), a force sensor, etc.

[0155] In some embodiments, the cleaning device 100 may further include a controller 111. The controller 111 may be a control device integrated into the cleaning device 100 itself, or it may be a control device additionally installed in the cleaning device 100. This application does not impose any limitations. Please refer to... Figure 10 Pump 131, three-way valve 170, and detection element 112 are all electrically connected to controller 111. Controller 111 receives detection signals from detection element 112 to determine the type of floor surface in the area to be cleaned, and then controls the working state of three-way valve 170 and pump 131. In embodiments where the cleaning equipment 100 also includes an angle adjustment component 180, the angle adjustment component 180 is also electrically connected to controller 111 and is controlled by controller 111 to adjust the spray direction of nozzle 150.

[0156] A second aspect of this application provides a cleaning device 100, which can be a floor scrubber, vacuum cleaner, robotic vacuum cleaner, or other cleaning device with a vacuuming function. The cleaning device 100 also includes a main body 110, and a suction power element, a sludge collection box, and a suction pipe 120 installed on the main body 110. The sludge collection box is connected to the suction pipe 120, and dust, hair, and other debris from the area to be cleaned enter the sludge collection box through the suction pipe 120. The exhaust port of the suction power element is connected to the sludge collection box, drawing air out of the sludge collection box. A filter covers the exhaust port to prevent particulate matter from entering the suction power element.

[0157] Please see Figure 11The cleaning device 100 of the second aspect embodiment of this application further includes a liquid supply assembly 130, a second pipeline 140, and a nozzle 150 connected in sequence. The liquid supply assembly 130, the second pipeline 140, and the nozzle 150 are connected in sequence. The nozzle 150 is installed on the pipe wall 121 of the suction pipe 120, and the nozzle 151 of the nozzle 150 is connected to the cavity 120a of the suction pipe 120. The liquid supply assembly 130 supplies liquid to the nozzle 150 through the second pipeline 140. For more detailed information about the liquid supply assembly 130, the second pipeline 140, and the nozzle 150, please refer to the relevant description of the first aspect embodiment of this application, which will not be repeated here.

[0158] In some embodiments, the cleaning device 100 further includes a cleaning component 160 and a three-way valve 170. The liquid supply assembly 130 includes a liquid supply component 133, a pump 131, and a first pipeline 132 connected in sequence. The inlet of the three-way valve 170 is connected to the pump 131, and the two outlets of the three-way valve 170 are respectively connected to the first pipeline 132 and the second pipeline 140. The liquid entering the first pipeline 132 eventually flows to the cleaning component 160; the liquid entering the second pipeline 140 eventually flows to the nozzle 150. This allows the pump 131 to selectively pump liquid to either the nozzle 150 or the cleaning component 160. For more detailed descriptions of the liquid supply component 133, the pump 131, the first pipeline 132, the cleaning component 160, and the three-way valve 170, please refer to the relevant descriptions of the embodiments of the first aspect of this application, which will not be repeated here.

[0159] Please see Figure 11 and Figure 12 Unlike the first aspect of this application, in the cleaning device 100 of the second aspect of this application, the nozzle 150 is movably mounted on the pipe wall 121 of the suction pipe 120. For example, the nozzle 150 can slide, rotate, or both slide and rotate relative to the pipe wall 121 of the suction pipe 120. The nozzle 150 can be movably connected to the pipe wall 121 through components such as universal joints, ball joints, hoses, flexible sleeves, and bearings, which is not limited in this application. Based on this, the cleaning device 100 of the second aspect of this application also includes an angle adjustment member 180. The angle adjustment member 180 can change the installation angle of the nozzle 150 through its own movement, thereby changing the spray direction of the nozzle 150.

[0160] The output end of the angle adjustment element 180 is connected to at least one of the second pipe 140 and the nozzle 150 to change the spray direction of the nozzle 150. Exemplarily, the angle adjustment element 180 can be an active drive element, such as a motor-driven crank-rocker mechanism, where the rocker arm of the crank-rocker mechanism is connected to a universal joint 124. The crank-rocker mechanism converts the rotation angle of the motor into a change in the attitude of the universal joint 124, thereby adjusting the installation angle of the nozzle 150. The angle adjustment element 180 can also be a motor-driven gear set, or a telescopic element such as a cylinder or an electric telescopic rod, which directly drives the nozzle 150 to adjust its attitude.

[0161] In other embodiments, the angle adjustment member 180 can also be a passive drive member, that is, the angle adjustment member 180 itself cannot generate driving force, but can only transmit external forces. For example, the angle adjustment member 180 can be an extended handle, which the consumer can operate to change the spray direction of the nozzle 150, so that the nozzle 150 continuously changes angle to flush the suction pipe 120.

[0162] The output end of the angle adjusting component 180 can directly act on at least one of the second pipe 140 and the nozzle 150, and can change the spray direction of the nozzle 150. This application does not limit the specific type of the angle adjusting component 180, nor the connection method between the angle adjusting component 180 and the second pipe 140 and the nozzle 150.

[0163] In some embodiments, the main body 110 of the device also includes a controller 111 and a detection element 112. The detection element 112 detects the type of the floor in the area to be cleaned. The pump 131, the three-way valve 170, the angle adjustment element 180, and the detection element 112 are all electrically connected to the controller 111. The controller 111 receives the detection signal from the detection element 112 to determine the type of the floor in the area to be cleaned, and then controls the working state of the three-way valve 170 and the pump 131. In self-cleaning mode, the controller 111 controls the angle adjustment element 180 to adjust the spray direction of the nozzle 150, thereby changing the spray angle of the nozzle 150 as it scours the suction pipe 120.

[0164] A third aspect of this application provides a cleaning device 100, which can be a floor scrubber, vacuum cleaner, robotic vacuum cleaner, or other cleaning device with a vacuuming function. The cleaning device 100 also includes a main body 110, and a suction power element, a sludge collection box, and a suction pipe 120 installed on the main body 110. The sludge collection box is connected to the suction pipe 120, and dust, hair, and other debris from the area to be cleaned enter the sludge collection box through the suction pipe 120. The exhaust port of the suction power element is connected to the sludge collection box, drawing air out of the sludge collection box. A filter covers the exhaust port to prevent particulate matter from entering the suction power element.

[0165] Please see Figure 13 Unlike the first aspect of the embodiment, the cleaning device 100 of the second aspect of the embodiment further includes a functional component 190. The functional component 190 is installed on the wall 121 of the suction pipe 120, and its emitting end is connected to the cavity 120a of the suction pipe 120. The functional component 190 emits a medium into the cavity 120a of the suction pipe 120. This medium has at least one of the functions of sterilization, disinfection, and deodorization, such as plasma, negative ions, ultraviolet light, or ozone. The medium output by the functional component 190 enters the suction pipe 120, contacts and mixes with the airflow within the suction pipe 120, and enters the sludge collection tank along with the airflow, thereby purifying and disinfecting the suction pipe 120 and the sludge collection tank.

[0166] In one optional embodiment, functional component 190 is a negative ion generator; in another optional embodiment, functional component 190 is an ultraviolet light source. Further embodiments of functional component 190 are not exhaustive. The connection structure between functional component 190 and the suction pipe 120, the installation position of functional component 190 on the suction pipe 120, and the installation posture are analogous to the nozzle 150 of the cleaning device 100 of the first aspect embodiment of this application. That is, functional component 190 can directly replace the nozzle 150 of the cleaning device 100 of the first aspect embodiment of this application. Therefore, the connection structure between functional component 190 and the suction pipe 120, the installation position of functional component 190 on the suction pipe 120, and the installation posture, etc., can all refer to the relevant description of the nozzle 150 in the first aspect embodiment of this application, and will not be repeated here.

[0167] In some embodiments, the cleaning device 100 may also include a functional component 190 and a nozzle 150. That is, the cleaning device 100 includes at least a functional component 190, a liquid supply assembly 130, a second conduit 140, and a nozzle 150. The functional component 190 is installed on the wall 121 of the suction pipe 120, and its transmitting end is connected to the cavity 120a of the suction pipe 120. The liquid supply assembly 130, the second conduit 140, and the nozzle 150 are sequentially connected. The nozzle 150 is installed on the wall 121 of the suction pipe 120, and its nozzle 151 is connected to the cavity 120a of the suction pipe 120. The liquid supply assembly 130 supplies liquid to the nozzle 150 through the second conduit 140. Thus, the cleaning device 100 in these embodiments simultaneously possesses both dust suppression and sterilization / disinfection functions. For more detailed information regarding the liquid supply assembly 130, the second conduit 140, and the nozzle 150, please refer to the relevant description of the first aspect of the embodiments of this application, which will not be repeated here.

[0168] A fourth aspect of this application provides a control method for a cleaning device 100. The cleaning device 100 can be a floor scrubber, vacuum cleaner, sweeping robot, or other cleaning device with a vacuuming function, capable of cleaning dirt from an area to be cleaned. The cleaning device 100 includes a suction power element, a suction pipe 120, and a media supply element. The suction power element is connected to the suction pipe 120, providing suction to draw dirt from the area to be cleaned into the suction pipe 120, which then flows into a collection tank. The output end of the media supply element is connected to the cavity 120a of the suction pipe 120.

[0169] The medium provided by the medium provider can be at least one of atomized droplets, liquid flow (referring to a liquid in a flowing state), negative ions, ultraviolet light, plasma, and ozone. The liquid can be clean water, cleaning agent, disinfectant, floor protectant, or a mixture of the above liquids. This application does not limit the specific type or state of the medium. Correspondingly, the medium provider can include at least one of a nozzle 150 and a functional component 190. The functional component 190 can be at least one of a negative ion generator, an ultraviolet light source, and a plasma generator. For details regarding the functional component 190, please refer to the description of the functional component 190 in the third aspect embodiment of this application; it will not be repeated here.

[0170] In some embodiments, the medium supply component includes at least a nozzle 150, with the nozzle 151 communicating with the cavity 120a of the suction pipe 120. The liquid sprayed from the nozzle 150 can be supplied by an external water pipe or by a liquid supply assembly 130 provided in the cleaning device 100. In some embodiments, the cleaning device 100 also includes a pump 131, with the nozzle 150 communicating with the pump 131. The nozzle 150 is mounted on the suction pipe 120. The mounting position, mounting posture, and connection structure of the nozzle 150 on the suction pipe 120 can be found in the description of the nozzle 150 in the first aspect of this application, and will not be repeated here.

[0171] In some embodiments, the cleaning device 100 further includes a cleaning component 160. The cleaning device 100 is configured to switch between a vacuuming mode and a floor-washing mode. When the cleaning device 100 is in vacuuming mode, it performs dry cleaning on at least a first surface to be cleaned; when the cleaning device 100 is in floor-washing mode, it performs wet cleaning on at least a second surface to be cleaned. It is understood that the cleaning device 100 may also perform dry cleaning on the second surface to be cleaned when in vacuuming mode, and wet cleaning on the first surface to be cleaned when in floor-washing mode.

[0172] In some embodiments, the first surface to be cleaned and the second surface to be cleaned are of different types. For example, the first surface to be cleaned may be a soft surface with some fibers, while the second surface to be cleaned may be a relatively flat hard surface. In other embodiments, the first surface to be cleaned and the second surface to be cleaned have different degrees of dirt. For example, the dirt level of the first surface to be cleaned is less than a set threshold, while the dirt level of the second surface to be cleaned is greater than a set threshold. The embodiments of this application do not limit the specific content of the first surface to be cleaned and the second surface to be cleaned.

[0173] In the dry cleaning process of the first surface to be cleaned, at least a suction power element and a media supply element are used by the cleaning equipment 100 during operation. The suction power element provides suction to draw the dirt from the first surface to be cleaned into the suction pipe 120. The media supply element outputs a medium into the cavity 120a of the suction pipe 120, which mixes with the dirt inside the suction pipe 120. In the wet cleaning process of the second surface to be cleaned, at least a suction power element and a cleaning component 160 are used by the cleaning equipment 100 during operation. The cleaning component 160 is in a wet state. After starting, the cleaning component 160 rotates and comes into contact with the second surface to be cleaned. The cleaning component 160 wets the second surface to be cleaned and then scrubs it to remove the dirt. The removed dirt mixes with the liquid contained in the cleaning component 160 to form wastewater. The suction power element provides suction to draw the wastewater and the dirt on the surface of the cleaning component 160 into the suction pipe 120.

[0174] In some embodiments, the medium supply device further includes a second conduit 140, the two ends of which are connected to the nozzle 150 and the pump 131, respectively. The specific installation position and installation structure of the second conduit 140 can be referred to the relevant description of the second conduit 140 in the first aspect embodiment of this application, and will not be repeated here.

[0175] The cleaning component 160 is in a wet state, which can be achieved by soaking the cleaning component 160 or by supplying liquid to the cleaning component 160; this application is not limited to this. In some embodiments, the cleaning device 100 further includes a pump 131 and a water distributor 136, with the pump 131 and the water distributor 136 connected by a pipe. That is, the pump 131 is simultaneously connected to the water distributor 136 and the nozzle 150. The water distributor 136 has a liquid outlet facing the cleaning component 160, capable of spraying liquid onto the cleaning component 160 or onto the ground below the cleaning component 160. The water distributor 136 can be a nozzle or a water distributor; the specific structures of the nozzle and the water distributor can be found in relevant prior art disclosures, which will not be elaborated here.

[0176] In some embodiments, the liquid supply assembly 130 further includes a three-way valve 170, the inlet of which is connected to the pump 131, and the two outlets of which are connected to the water distributor 136 and the second pipeline 140, respectively. The specific operating state of the three-way valve 170 can be found in the relevant description of the three-way valve 170 in the first aspect of this application, and will not be repeated here.

[0177] The liquid supplied by pump 131 can be from an external water source or from the liquid storage device built into the cleaning equipment 100. In some embodiments, the liquid supply assembly 130 further includes a liquid supply element 133 for storing liquid, which can be clean water, cleaning agent, disinfectant, floor protectant, or a mixture of the above liquids, etc. The user can select different types of liquids according to actual usage needs. For details regarding the liquid supply element 133, please refer to the relevant description of the liquid supply element 133 in the first aspect embodiment of this application, which will not be repeated here.

[0178] In some embodiments, the nozzle 150 is movably mounted to the wall 121 of the suction pipe 120. For example, the nozzle 150 can slide, rotate, or both slide and rotate relative to the wall 121 of the suction pipe 120. The cleaning device 100 may also include an angle adjustment member 180. The angle adjustment member 180 can change the installation angle of the nozzle 150 through its own movement, thereby changing the spray direction of the nozzle 150. For details regarding the angle adjustment member 180 and the connection method between the nozzle 150 and the wall 121 of the suction pipe 120, please refer to the relevant description of the angle adjustment member 180 and the nozzle 150 in the second aspect embodiment of this application, which will not be repeated here.

[0179] In some embodiments, the cleaning device 100 may further include a detection element 112 for detecting the surface of the area to be cleaned. The detection element 112 can detect light reflection signals, friction coefficients, etc., of the surface of the area to be cleaned, and the surface type of the area to be cleaned can be determined based on the detection signals of the detection element 112. For details regarding the detection element 112, please refer to the relevant description of the detection element 112 in the first aspect embodiment of this application, which will not be repeated here.

[0180] In the above embodiments, the pump 131, three-way valve 170, angle adjustment component 180, and detection element 112 are all electrically connected to the controller 111. The controller 111 can be a control device that is built into the cleaning equipment 100 itself, or it can be a control device that is additionally installed in the cleaning equipment 100. This application does not impose any restrictions.

[0181] In actual implementation, the cleaning equipment 100 may also include other components, such as the main body 110, the sludge collection box, and the filter element. The components included in the cleaning equipment 100 will not be listed one by one here.

[0182] By adopting the above technical solution, the cleaning equipment 100 provided in this application embodiment integrates floor washing and vacuuming functions, and can switch between two cleaning modes. The cleaning mode of the cleaning equipment 100 can be flexibly changed according to needs to adapt to the area to be cleaned, so as to flexibly select the most suitable cleaning method when dealing with different types of stains or different floor materials, and achieve efficient and high-quality cleaning results. At the same time, the cleaning equipment 100 is equipped with a media supply component, which can output media into the suction pipe 120 during the dry cleaning of the first surface to be cleaned by the cleaning equipment 100, realizing at least one function such as dust reduction, disinfection, sterilization, and deodorization, thereby improving the user experience.

[0183] The control method of the cleaning equipment 100 provided in the embodiments of this application will be described in detail below.

[0184] The following embodiments illustrate the application of this control method to the cleaning device 100 in any of the embodiments described above. For example, the control method can be applied to the main control board of the cleaning device 100 in the above embodiments of this application. In other embodiments, the control method can also be executed by other devices that communicate with the cleaning device 100, such as remotely controlling the cleaning device 100 via a mobile phone, computer, tablet computer, or other device. This application does not limit the implementation methods of other devices or the execution entities of each embodiment.

[0185] Please see Figure 14 , Figure 14 A flowchart illustrating the overall process of controlling a cleaning device 100 according to certain embodiments of this application. The control method for the cleaning device 100 includes at least the following steps:

[0186] Step 1031A: In response to the vacuuming command, control the cleaning equipment 100 to enter the vacuuming mode.

[0187] Step 1032A: In vacuum mode, control the operation of the suction power unit to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to supply liquid medium to the cavity 120a of the suction pipe 120.

[0188] Because the nozzle 150 sprays liquid medium while the suction pipe 120 already contains airflow containing dirt, the liquid medium sprayed from the nozzle 150 collides with the airflow, causing turbulence. In this turbulent environment, the liquid mixes with the dirt, and the dust in the dirt mixes with the liquid to form wastewater. Small objects such as hair will be contaminated with liquid droplets, increasing their weight, as will other solid particles. When the dirt mixed with the liquid enters the collection tank of the cleaning device 100, the wastewater and the increased weight of the dirt due to water will fall to the bottom of the collection tank. Only a small amount of dust that has not come into contact with the liquid will float in the collection tank and be sucked into the filter with the airflow. By setting the nozzle 150 to convert dry dust into wastewater, the amount of dust in the collection tank is effectively reduced, thus effectively solving the dust problem. Furthermore, since most of the dirt falls to the bottom of the collection tank after being wetted, less dirt is scattered, preventing excessive contamination of filters such as HEPA filters, thereby reducing the frequency of cleaning and replacement of the filters.

[0189] Nozzle 150 can continuously spray liquid medium into suction pipe 120 or spray liquid medium intermittently. This application does not impose any limitations. The liquid medium sprayed by nozzle 150 can be a liquid flow or atomized droplets. The liquid pressure and the nozzle orifice 151 size of nozzle 150 can both affect the morphology of the liquid medium. For example, in some embodiments, nozzle 150 is an atomizing nozzle 150, in which case the liquid medium is atomized droplets; in other embodiments, nozzle 150 is a conventional nozzle 150, in which case the liquid medium is a liquid flow.

[0190] In some embodiments, the step 1032A of controlling the nozzle 150 to supply the liquid medium to the cavity 120a of the suction pipe 120 can be performed according to the following steps:

[0191] The control pump 131 pumps liquid to the nozzle 150 by continuous operation, so that the nozzle 150 sprays liquid into the cavity 120a of the suction pipe 120.

[0192] In other words, in vacuuming mode, the suction power unit operates continuously, causing dirt from the area to be cleaned to be drawn into the suction pipe 120, forming a dirty airflow. The pump 131 operates continuously to pump liquid to the nozzle 150, which continuously sprays atomized droplets into the cavity 120a of the suction pipe 120, thus achieving the dust suppression function in vacuuming mode.

[0193] Vacuuming commands can be triggered by a user clicking a button, which can be a physical button or a function icon on a touchscreen. This button can be located on the cleaning device 100 or on a mobile terminal that controls the cleaning device 100, such as a smartphone or tablet. Vacuuming commands can also be triggered by user gestures, such as tapping a specific area of ​​the cleaning device 100. Vacuuming commands can also be triggered by user voice commands. Vacuuming commands can also be triggered based on the detected floor type of the area to be cleaned. Many other methods of triggering vacuuming commands are not listed here.

[0194] Please see Figure 15 In some embodiments, after controlling the cleaning device 100 to enter the vacuuming mode in step 1031A, the control method may also be performed according to the following steps:

[0195] Step 1032A1: In vacuuming mode, control the cleaning unit 160 to perform dry cleaning of the area to be cleaned, and control the operation of the suction power element so that the dirt in the area to be cleaned removed by the cleaning unit 160 enters the suction pipe 120.

[0196] In some embodiments, the cleaning device 100 is configured to switch between a vacuuming mode and a floor-washing mode. When the cleaning device 100 is in vacuuming mode, it performs dry cleaning on at least the area to be cleaned; when the cleaning device 100 is in floor-washing mode, it performs wet cleaning on at least the area to be cleaned. Correspondingly, the control method further includes:

[0197] Step 1031B: In response to the floor washing command, control the cleaning equipment 100 to enter the floor washing mode.

[0198] Step 1032B: Control pump 131 to pump liquid to distributor 136 so that cleaning component 160 can use the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0199] In some embodiments, the step 1032B of controlling pump 131 to pump liquid to distributor 136 can be performed by controlling pump 131 to pump liquid to distributor 136 through intermittent operation.

[0200] The intermittent operation of pump 131 can be such that the working time and the interval (pause time) are the same, for example, working for 5 seconds at a 5-second interval. Alternatively, the working time and the interval can be different, for example, working for 4 seconds at a 3-second interval. Or, the working time and the interval can change according to a set pattern; for example, in the initial stage of the floor cleaning mode, pump 131 works for 3 seconds at a 3-second interval. After the set time is reached, pump 131 works for 5 seconds at a 5-second interval until cleaning is complete.

[0201] The floor cleaning command can be triggered by the user clicking a button, which can be a physical button or a function icon on a touchscreen. This button can be located on the cleaning device 100 or on a mobile terminal that controls the cleaning device 100, such as a mobile phone or tablet. The floor cleaning command can also be triggered by the user's gestures, such as tapping a specific area of ​​the cleaning device 100. The floor cleaning command can also be triggered by the user's voice commands. The floor cleaning command can also be triggered based on the detected floor type of the area to be cleaned. Many other methods of triggering the floor cleaning command are not listed here.

[0202] In some embodiments, the cleaning device 100 is configured to switch between a vacuuming mode and a floor-washing mode. When the cleaning device 100 is in vacuuming mode, it performs dry cleaning on at least a first surface to be cleaned; when the cleaning device 100 is in floor-washing mode, it performs wet cleaning on at least a second surface to be cleaned. It is understood that the cleaning device 100 may also perform dry cleaning on the second surface to be cleaned when in vacuuming mode, and wet cleaning on the first surface to be cleaned when in floor-washing mode.

[0203] In some embodiments, the first surface to be cleaned and the second surface to be cleaned are of different types. The first surface to be cleaned can be a soft surface with some fibers, such as a carpet, wool blanket, or floor mat. The second surface to be cleaned can be a relatively flat hard surface, such as a surface covered with ceramic flooring / tiles, wooden flooring / tiles, marble flooring / tiles, etc. This application does not limit the specific types of the first and second surfaces to be cleaned. Therefore, both vacuuming and cleaning commands can be triggered based on the detected surface type of the area to be cleaned.

[0204] Please see Figure 16 The diagram shows a flowchart of a control method for a cleaning device 100 in some embodiments of this application. The control method includes the following steps:

[0205] Step 101: In response to the work instruction, acquire the detection signal of the ground type of the area to be cleaned.

[0206] Work commands can be triggered by the user clicking a button, which can be a physical button or a function icon on a touchscreen. This button can be located on the cleaning device 100 or on a mobile terminal that can control the cleaning device 100, such as a mobile phone or tablet. Work commands can also be triggered by the user's gestures, such as tapping a specific area of ​​the cleaning device 100. Work commands can also be triggered by the user's voice commands. Work commands can also be triggered by user-defined signals, such as a timed activation of the cleaning function. Many other triggering methods for work commands are not listed here.

[0207] Step 102: Determine the floor type of the area to be cleaned based on the detection signal. If the floor type indicated by the detection signal is the first type, generate a vacuuming command. If the floor type indicated by the detection signal is the second type, generate a floor washing command.

[0208] Step 103: In response to the generated instructions, perform the corresponding cleaning operation. Step 103 specifically includes:

[0209] Step 103A: In response to a vacuuming command, control the operation of the vacuuming power unit to draw dirt from the area to be cleaned into the vacuuming pipe 120. Also, control the nozzle 150 to supply a liquid medium to the cavity 120a of the vacuuming pipe 120.

[0210] Step 103B: In response to the floor cleaning command, control pump 131 pumps liquid to distributor 136 so that cleaning component 160 uses the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0211] In step 101, a detection signal of the ground type of the area to be cleaned is acquired. This detection signal can be obtained by the detection element 112 or by receiving instructions transmitted from an external device. Therefore, the acquisition of this detection signal can be achieved through signal transmission via signal lines, wireless communication, etc., and this application does not impose any limitations.

[0212] In one specific embodiment, the detection element 112 is a light detection sensor, which detects the light reflection signal of the ground in the area to be cleaned. Generally, hard surfaces such as wooden floors reflect light more strongly, while soft surfaces such as carpets reflect light less strongly. Therefore, it can be determined whether the currently detected ground surface is the first surface to be cleaned based on the light reflection signal detected by the light detection sensor.

[0213] In other words, the detection signal for the surface type of the area to be cleaned obtained in step 101 is the light reflection signal of the surface of the area to be cleaned. Correspondingly, taking a hard surface as an example, step 102, which determines the surface type of the area to be cleaned based on the detection signal, can be performed as follows:

[0214] The system compares the light reflection signal with a set light reflection value. If the light reflection signal is higher than the set value, the detected floor type is determined to be a hard floor, and a vacuuming command is generated. Otherwise, a floor washing command is generated.

[0215] Please see Figure 17 In some embodiments, step 103 may also be performed as follows:

[0216] Step 103A1: In response to a vacuuming command, control the operation of the vacuuming power unit to draw dirt from the area to be cleaned into the vacuum pipe 120. Control the three-way valve 170 to connect the pump 131 to the nozzle 150. Also, control the pump 131 to pump liquid into the nozzle 150 so that the nozzle 150 uses the pumped liquid to provide a liquid medium to the cavity 120a of the vacuum pipe 120.

[0217] Step 103B1: In response to the floor cleaning command, control the three-way valve 170 to activate it, thereby connecting pump 131 to distributor 136. Control pump 131 to pump liquid to distributor 136, so that cleaning component 160 can use the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0218] A fifth aspect of this application provides a control method for a cleaning device 100, which can be a floor scrubber, vacuum cleaner, or robotic vacuum cleaner, capable of cleaning dirt from an area to be cleaned. The cleaning device 100 includes a suction pipe 120 and a nozzle 150, with the nozzle 151 of the nozzle 150 communicating with the cavity 120a of the suction pipe 120. The installation position, installation posture, and connection structure of the nozzle 150 on the suction pipe 120 can be found in the description of the nozzle 150 in the first aspect of this application, and will not be repeated here. Other undescribed aspects of the cleaning device 100 can be found in the description of the cleaning device 100 in the fourth aspect of this application, and will not be repeated here.

[0219] The cleaning device 100 has a self-cleaning mode, in which the cleaning device 100 performs at least wet cleaning of the suction pipe 120. Please refer to... Figure 18 The corresponding control methods include the following:

[0220] Step 2041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0221] Step 2042: In self-cleaning mode, control nozzle 150 to provide cleaning medium to cavity 120a of suction pipe 120.

[0222] The cleaning medium uses its own kinetic energy and / or fluidity to clean the inner wall of the suction pipe 120, forming a dirty fluid inside the suction pipe 120. If the cleaning medium is a liquid, the dirty fluid corresponds to sewage; if the cleaning medium is an airflow, the dirty fluid corresponds to dusty gas.

[0223] The nozzle 150 can continuously spray cleaning medium into the suction pipe 120, or it can spray cleaning medium intermittently. This application does not impose any limitations. The cleaning medium sprayed by the nozzle 150 can be a liquid stream, atomized droplets, or an airflow. The liquid composition can be water, cleaning agent, disinfectant, floor protectant, or a mixture of the above liquids, etc., and the user can choose different types of liquids according to actual usage needs.

[0224] Please see Figure 19 In some embodiments, after controlling the cleaning device 100 to enter the self-cleaning mode in step 2041, the control method may also be performed according to the following steps:

[0225] Step 2042a: In self-cleaning mode, the nozzle 150 is controlled to supply cleaning medium to the cavity 120a of the suction pipe 120. Additionally, the suction power unit is controlled to operate so that the dirty fluid within the suction pipe 120 enters the collection tank.

[0226] The self-cleaning command can be triggered by the user clicking a button, which can be a physical button or a function icon on a touchscreen. This button can be located on the cleaning device 100 or on a mobile terminal that controls the cleaning device 100, such as a mobile phone or tablet. The self-cleaning command can also be triggered by the user's gestures, such as tapping a specific area of ​​the cleaning device 100. It can also be triggered by the user's voice commands. Furthermore, it can be triggered by user-defined signals, such as a timed start for the cleaning function. The self-cleaning command can also be triggered when set conditions are met, such as vacuuming completion, floor cleaning completion, or excessive dirt accumulation on the cleaning component 160. Many other triggering methods for the self-cleaning command are not listed here.

[0227] Please see Figure 20 The diagram shows a flowchart of a control method in some embodiments, which includes the following steps:

[0228] Step 2031A: In response to the vacuuming command, control the cleaning equipment 100 to enter the vacuuming mode.

[0229] Step 2032A: In vacuum mode, control the operation of the suction power unit to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to supply liquid medium to the cavity 120a of the suction pipe 120.

[0230] Step 2033A: The vacuuming mode ends, and a self-cleaning command is generated.

[0231] In some embodiments, the vacuuming mode ends once the area to be cleaned is confirmed to be clean. At this time, the cleaning device 100 switches from vacuuming mode to self-cleaning mode and generates a self-cleaning command accordingly. Determining that the area to be cleaned is clean can be done manually by the user, for example, by clicking the self-cleaning button, at which point the cleaning device 100 switches from vacuuming mode to self-cleaning mode, which can be considered as confirming that the area to be cleaned is clean. Alternatively, the cleaning device 100 can automatically recognize the end of the vacuuming mode. For example, the cleaning device 100 cleans the room in vacuuming mode according to a preset cleaning map; the vacuuming mode ends when all areas to be cleaned on the cleaning map have been vacuumed.

[0232] Step 2041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0233] Step 2042: In self-cleaning mode, control nozzle 150 to provide cleaning medium to cavity 120a of suction pipe 120.

[0234] In some embodiments, step 2032A, controlling the nozzle 150 to supply a liquid medium to the cavity 120a of the suction pipe 120, specifically includes:

[0235] The control pump 131 pumps liquid to the nozzle 150 through continuous operation at the first power, so that the nozzle 150 uses the liquid to spray liquid medium into the cavity 120a of the suction pipe 120.

[0236] In some embodiments, step 2042, which involves controlling the nozzle 150 to supply cleaning medium to the cavity 120a of the suction pipe 120, can be performed as follows:

[0237] The control pump 131 pumps liquid to the nozzle 150 through continuous operation at the second power, so that the nozzle 150 uses the liquid to spray cleaning medium into the cavity 120a of the suction pipe 120.

[0238] The controlled nozzles 150 in steps 2032A and 2042 can be the same nozzle 150 or different nozzles 150. In steps 2032A and 2042, pump 131 operates continuously at a first power and a second power, respectively. In some embodiments, the first power is less than the second power. It is understood that in vacuuming mode, pump 131 is in a low-power, normally open state, and nozzle 150 sprays dust into the suction pipe 120. Because the liquid flow rate required for dust reduction is small, the operating power of pump 131 is relatively low. In self-cleaning mode, pump 131 is in a high-power, normally open state, and nozzle 150 sprays liquid to remove dirt into the suction pipe 120. Because the liquid flow rate required to flush the pipe wall 121 is large, the operating power of pump 131 is relatively high.

[0239] In some embodiments, the cleaning device 100 is configured to switch between a vacuuming mode and a floor-washing mode. When the cleaning device 100 is in vacuuming mode, it performs dry cleaning on at least a first surface to be cleaned; when the cleaning device 100 is in floor-washing mode, it performs wet cleaning on at least a second surface to be cleaned. It is understood that the cleaning device 100 may also perform dry cleaning on the second surface to be cleaned while in vacuuming mode, and wet cleaning on the first surface to be cleaned while in floor-washing mode. It automatically enters a self-cleaning mode after either dry or wet cleaning is completed. See also... Figure 21 The flowchart of the control method for the cleaning device 100 is shown. The control method includes the following steps:

[0240] Step 2031A: In response to the vacuuming command, control the cleaning equipment 100 to enter the vacuuming mode.

[0241] Step 2032A: In vacuum mode, control the operation of the suction power unit to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to supply liquid medium to the cavity 120a of the suction pipe 120.

[0242] Step 2031B: In response to the floor washing command, control the cleaning equipment 100 to enter the floor washing mode.

[0243] Step 2032B: In the floor cleaning mode, control pump 131 pumps liquid to distributor 136 so that cleaning component 160 uses the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0244] Step 2033: Vacuuming mode / floor washing mode ends, generating a self-cleaning command.

[0245] Once the dirt in the area to be cleaned has been removed, the vacuuming / floor washing mode ends. At this point, the cleaning device 100 switches from vacuuming / floor washing mode to self-cleaning mode, generating a corresponding self-cleaning command.

[0246] Step 2041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0247] Step 2042: In self-cleaning mode, control nozzle 150 to provide cleaning medium to cavity 120a of suction pipe 120.

[0248] Please see Figure 22 In some embodiments, after controlling the cleaning device 100 to enter the self-cleaning mode in step 2041, the control method may also be performed according to the following steps:

[0249] Step 20421: In self-cleaning mode, control the cleaning component 160 to self-clean. Specifically, this includes:

[0250] In response to a self-cleaning command, the control pump 131 pumps liquid to the distributor 136 so that the cleaning component 160 can perform self-cleaning using the liquid output from the distributor 136. Additionally, the control pump 131 operates so that the wastewater generated by the self-cleaning of the cleaning component 160 is drawn into the suction pipe 120 and ultimately into the collection tank.

[0251] After the self-cleaning of cleaning component 160 is completed, proceed to step 20422.

[0252] In actual operation, the degree of dirtiness of the wastewater generated by the self-cleaning component 160 can be used to determine whether the self-cleaning of the cleaning component 160 has ended. For example, if the degree of dirtiness of the wastewater generated by the self-cleaning is less than the set condition, then the self-cleaning of the cleaning component 160 is determined to be over. In some embodiments, the self-cleaning time of the cleaning component 160 can also be set, and the self-cleaning of the cleaning component 160 is determined to be over after the self-cleaning time of the cleaning component 160 reaches the set duration.

[0253] Step 20422: Control the self-cleaning of the suction pipe 120. Specifically, this includes:

[0254] The control pump 131 pumps liquid to the nozzle 150 so that the nozzle 150 provides cleaning medium to the cavity 120a of the suction pipe 120. Also, the control pump 131 operates so that wastewater in the suction pipe 120 enters the collection tank.

[0255] Please see Figure 23 The diagram shows a flowchart of a control method for a cleaning device 100 in some other embodiments of this application. The control method includes the following steps:

[0256] Step 201: In response to the work instruction, acquire the detection signal of the ground type of the area to be cleaned.

[0257] Work commands can be triggered by the user clicking a button, which can be a physical button or a function icon on a touchscreen. This button can be located on the cleaning device 100 or on a mobile terminal that can control the cleaning device 100, such as a mobile phone or tablet. Work commands can also be triggered by the user's gestures, such as tapping a specific area of ​​the cleaning device 100. Work commands can also be triggered by the user's voice commands. Work commands can also be triggered by user-defined signals, such as a timed activation of the cleaning function. Many other triggering methods for work commands are not listed here.

[0258] Step 202: Determine the floor type of the area to be cleaned based on the detection signal. If the floor type indicated by the detection signal is the first type, generate a vacuuming command. If the floor type indicated by the detection signal is the second type, generate a floor washing command.

[0259] Step 203: In response to the generated instructions, perform the corresponding cleaning operation. Step 203 specifically includes:

[0260] Step 2031A: In response to the vacuuming command, control the cleaning equipment 100 to enter the vacuuming mode.

[0261] Step 2032A: In vacuum mode, control the operation of the suction power unit to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to supply liquid medium to the cavity 120a of the suction pipe 120.

[0262] Step 2031B: In response to the floor washing command, control the cleaning equipment 100 to enter the floor washing mode.

[0263] Step 2032B: In the floor cleaning mode, control pump 131 pumps liquid to distributor 136 so that cleaning component 160 uses the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0264] Step 2033: Cleaning operation completed, self-cleaning instruction generated.

[0265] In some embodiments, the cleaning operation ends once the dirt in the area to be cleaned is confirmed to have been removed. At this time, the cleaning device 100 switches from vacuuming mode / floor washing mode to self-cleaning mode and generates a self-cleaning command accordingly. Determining that the dirt in the area to be cleaned has been removed can be done manually by the user, for example, by the user clicking the self-cleaning button, at which point the cleaning device 100 switches to self-cleaning mode, which can be considered as confirming that the dirt in the area to be cleaned has been removed. Alternatively, the cleaning device 100 can automatically recognize the end of the vacuuming / floor washing mode. For example, the cleaning device 100 cleans the room according to a preset cleaning map using vacuuming / floor washing mode; when all areas to be cleaned on the cleaning map have been vacuumed / washed, the vacuuming / floor washing mode ends.

[0266] Step 2041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0267] Step 2042: In self-cleaning mode, control nozzle 150 to provide cleaning medium to cavity 120a of suction pipe 120.

[0268] Please see Figure 24 The diagram shows a flowchart of a control method for a cleaning device 100 in some embodiments of this application. The control method includes the following steps:

[0269] Step 201: In response to the work instruction, acquire the detection signal of the ground type of the area to be cleaned.

[0270] Step 202: Determine the ground type of the area to be cleaned based on the detection signal. Step 202 specifically includes:

[0271] Step 202A: If the floor type of the area to be cleaned indicated by the detection signal is the first surface to be cleaned, a vacuuming command is generated; and the three-way valve 170 is controlled to operate so that the pump 131 is connected to the nozzle 150.

[0272] Step 202B: If the floor type of the area to be cleaned indicated by the detection signal is the second surface to be cleaned, generate a floor cleaning command; and control the three-way valve 170 to activate so that the pump 131 is connected to the water distributor 136.

[0273] Step 2031A: In response to the vacuuming command, control the cleaning equipment 100 to enter the vacuuming mode.

[0274] Step 2032A: In vacuum mode, control the operation of the suction power unit to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to supply liquid medium to the cavity 120a of the suction pipe 120.

[0275] Step 2031B: In response to the floor washing command, control the cleaning equipment 100 to enter the floor washing mode.

[0276] Step 2032B: In the floor cleaning mode, control pump 131 pumps liquid to distributor 136 so that cleaning component 160 uses the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0277] Step 2033: Vacuuming mode / floor washing mode ends, generating a self-cleaning command.

[0278] Step 2041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0279] Step 2042a: In self-cleaning mode, control the three-way valve 170 to connect the pump 131 to the nozzle 150, and control the pump 131 to pump liquid to the nozzle 150 so that the nozzle 150 provides cleaning medium to the cavity 120a of the suction pipe 120.

[0280] Therefore, the control method of the cleaning equipment 100 provided in the fifth aspect embodiment of this application enables the cleaning equipment 100 to have multiple functions such as dry vacuuming, spray dust removal, wet floor cleaning, self-cleaning of cleaning component 160, and self-cleaning of suction pipe 120, which can meet the various usage needs of consumers.

[0281] A sixth aspect of this application provides a control method for a cleaning device 100, which can be a floor scrubber, vacuum cleaner, sweeping robot, etc., capable of cleaning dirt in an area to be cleaned. The cleaning device 100 includes a suction power element, a suction pipe 120, and a nozzle 150, with the nozzle 151 communicating with the cavity 120a of the suction pipe 120. The installation position and orientation of the nozzle 150 on the suction pipe 120, as well as the connection structure between the nozzle 150 and the suction pipe 120, can be found in the description of the nozzle 150 in the first aspect of this application, and will not be repeated here. Other undescribed aspects of the cleaning device 100 can be found in the description of the cleaning device 100 in the fourth aspect of this application, and will not be repeated here.

[0282] The cleaning device 100 has a vacuuming mode and a self-cleaning mode. In vacuuming mode, the cleaning device 100 performs dry cleaning on at least the first surface to be cleaned. In self-cleaning mode, the cleaning device 100 performs wet cleaning on at least the suction pipe 120. See also... Figure 25 The corresponding control methods include the following steps:

[0283] Step 3031: In response to the vacuuming command, control the cleaning equipment 100 to enter the vacuuming mode.

[0284] The method for triggering the vacuuming command can be found in the description of the vacuuming command in the fourth aspect of this application, and will not be repeated here.

[0285] Step 3032: In vacuuming mode, control the operation of the suction power element to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to provide a first medium to the cavity 120a of the suction pipe 120 in a first preset posture.

[0286] The first medium is a liquid medium, specifically a liquid flow or atomized droplets. In some embodiments, the first medium is atomized droplets. The atomized droplets collide with the airflow containing dirt in the suction pipe 120. The atomized droplets mix with the dirt, and the dust in the dirt mixes with the liquid to form wastewater, thereby converting dry dust into wet wastewater, effectively reducing the amount of dust in the sludge collection box and thus effectively solving the dust problem. Furthermore, since most of the dirt settles at the bottom of the sludge collection box after being wetted, less dirt is dispersed, preventing excessive contamination of HEPA filters and thus reducing the frequency of cleaning and replacement of the filters.

[0287] In some embodiments, the first preset posture is a fixed posture. When the nozzle 150 is in the first preset posture, the spray direction of the nozzle 150 has a projection component parallel to the suction direction of the suction pipe 120. That is, the spray direction of the nozzle 150 can be parallel to the suction direction of the suction pipe 120, or have an angle of no more than 90° with the suction direction of the suction pipe 120, so that the first medium sprayed by the nozzle 150 has a motion component along the suction direction of the suction pipe 120, and can move together with the airflow in the suction pipe 120 without generating excessive flow resistance to hinder the airflow in the suction pipe 120. In some embodiments, when the nozzle 150 is in the first preset posture, the angle between the spray direction of the nozzle 150 and the suction direction of the suction pipe 120 is no more than 45°.

[0288] Step 3041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0289] The method for triggering the self-cleaning command can be found in the description of the self-cleaning command in the fifth aspect embodiment of this application, and will not be repeated here. In some embodiments, the vacuuming mode is interpreted to generate the self-cleaning command.

[0290] Step 3042: In self-cleaning mode, control the nozzle 150 to provide the second medium to the cavity 120a of the suction pipe 120 in the second preset posture.

[0291] The second medium uses its own kinetic energy and / or fluidity to clean the inner wall of the suction pipe 120, forming a dirty fluid inside the suction pipe 120. If the second medium is a gaseous medium, the dirty fluid corresponds to dust-laden gas; if the second medium is a liquid medium, the dirty fluid corresponds to sewage. When the second medium is a liquid medium, it can be a liquid flow or atomized droplets. In some embodiments, the second medium is a liquid flow. The components of the liquid medium can be water, cleaning agents, disinfectants, floor protectants, or mixtures of the above liquids, etc., and the user can select different types of liquids according to actual usage needs.

[0292] In some embodiments, the second preset posture is a variable posture. When the nozzle 150 is in the second preset posture, the spray direction of the nozzle 150 is not unique. That is, in self-cleaning mode, the spatial posture of the nozzle 150 changes, causing the spray direction of the nozzle 150 to change. As one implementation, the spray direction of the nozzle 150 can change intermittently. For example, in the first stage, the spray direction of the nozzle 150 is perpendicular to the suction direction of the suction pipe 120; in the second stage, the spray direction of the nozzle 150 has an angle between the spray direction of the nozzle 150 and the suction direction of the suction pipe 120 within the range of 45° to 90°; in the third stage, the spray direction of the nozzle 150 has an angle between the spray direction of the nozzle 150 and the suction direction of the suction pipe 120 within the range of 0° to 45°. As another implementation, the spray direction of the nozzle 150 can change continuously. For example, the angle between the spray direction of the nozzle 150 and the suction direction of the suction pipe 120 gradually changes from 0° to 180° (the spray direction of the nozzle 150 is parallel to and opposite to the suction direction of the suction pipe 120). Another example is that the movement trajectory of the nozzle 150 is an S-curve from top to bottom. Yet another example is that the movement trajectory of the nozzle 150 is a spiral from top to bottom.

[0293] In self-cleaning mode, the nozzle 150 continuously changes angle to scour the suction pipe 120, which can clean all parts of the suction pipe 120 and impact the dirt inside the suction pipe 120 from different directions, thereby improving the cleaning effect of the suction pipe 120.

[0294] In some embodiments, step 3042, which controls the nozzle 150 to provide the second medium to the cavity 120a of the suction pipe 120 in a second preset posture, can be performed according to the following steps:

[0295] The angle adjustment component 180 is activated to allow the nozzle 150 to supply a second medium to the cavity 120a of the suction pipe 120 in different spray directions.

[0296] In other words, in self-cleaning mode, at least the suction power element, pump 131, and angle adjustment element 180 are used as components when the cleaning device 100 performs its work. The angle adjustment element 180 can be actively driven to continuously change the angle of the nozzle 150 to flush the suction pipe 120. The angle adjustment element 180 can change the spatial posture of the nozzle 150 through its own operation, for example, driving the nozzle 150 to continuously change its angle according to an S-curve or spiral motion trajectory. As an optional implementation, the angle adjustment element 180 may include a stepper motor and a cable. One end of the cable is wound around the output shaft of the stepper motor, and the other end is connected to the nozzle 150. By inputting different electrical pulse signals to the stepper motor, the stepper motor can output different angular displacements. The output shaft of the stepper motor winds the cable to tighten it, and the cable drives the nozzle 150 to change its angle. More detailed information about the angle adjustment element 180 can be found in the relevant descriptions of the first and second aspects of this application, and will not be repeated here.

[0297] In some embodiments, step 3032, which controls the nozzle 150 to provide the first medium to the cavity 120a of the suction pipe 120 in a first preset posture, can be performed according to the following steps:

[0298] The control pump 131 pumps liquid to the nozzle 150 through continuous operation at a first power, so that the nozzle 150 uses the liquid to provide a first medium to the cavity 120a of the suction pipe 120 in a first preset posture.

[0299] In some embodiments, step 3042, which controls the nozzle 150 to provide the second medium to the cavity 120a of the suction pipe 120 in a second preset posture, can be performed according to the following steps:

[0300] The control pump 131 pumps liquid to the nozzle 150 through continuous operation at the second power, so that the nozzle 150 uses the liquid to provide a second medium to the cavity 120a of the suction pipe 120 in a second preset posture.

[0301] The controlled nozzles 150 in steps 3032A and 3042 can be the same nozzle 150 or different nozzles 150. In steps 3032A and 3042, pump 131 operates continuously at a first power and a second power, respectively. In some embodiments, the first power is less than the second power. It is understood that in vacuuming mode, pump 131 is in a low-power, normally open state, and nozzle 150 sprays dust into the suction pipe 120. Because the liquid flow rate required for dust reduction is small, the operating power of pump 131 is relatively low. In self-cleaning mode, pump 131 is in a high-power, normally open state, and nozzle 150 sprays liquid to remove dirt into the suction pipe 120. Because the liquid flow rate required to flush the pipe wall 121 is large, the operating power of pump 131 is relatively high.

[0302] In some embodiments, the cleaning device 100 also has a floor-washing mode. When the cleaning device 100 is in floor-washing mode, it performs wet cleaning on at least a second surface to be cleaned. See also... Figure 26 The corresponding control methods include the following steps:

[0303] Step 301: In response to the work instruction, acquire the detection signal of the ground type of the area to be cleaned.

[0304] Step 302: Determine the ground type of the area to be cleaned based on the detection signal. Step 302 specifically includes:

[0305] Step 302A: If the floor type of the area to be cleaned indicated by the detection signal is the first surface to be cleaned, a vacuuming command is generated; and the three-way valve 170 is controlled to operate so that the pump 131 is connected to the nozzle 150.

[0306] Step 302B: If the floor type of the area to be cleaned indicated by the detection signal is the second surface to be cleaned, generate a floor cleaning command; and control the three-way valve 170 to activate so that the pump 131 is connected to the water distributor 136.

[0307] Step 3031A: In response to the vacuuming command, control the cleaning equipment 100 to enter the vacuuming mode.

[0308] Step 3032A: In vacuuming mode, control the operation of the suction power element to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to provide a first medium to the cavity 120a of the suction pipe 120 in a first preset posture.

[0309] Step 3031B: In response to the floor washing command, control the cleaning equipment 100 to enter the floor washing mode.

[0310] Step 3032B: In the floor cleaning mode, control pump 131 pumps liquid to distributor 136 so that cleaning component 160 uses the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0311] Step 3033: Vacuuming mode / floor washing mode ends, generating self-cleaning command.

[0312] Step 3041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0313] Step 3042a: In self-cleaning mode, control the three-way valve 170 to connect the pump 131 to the nozzle 150, control the pump 131 to pump liquid to the nozzle 150, so that the nozzle 150 provides the second medium to the cavity 120a of the suction pipe 120 in the second preset posture.

[0314] Therefore, the control method of the cleaning equipment 100 provided in the sixth aspect embodiment of this application enables the cleaning equipment 100 to have at least multiple functions such as dry vacuuming, spray dust removal, wet floor cleaning, and self-cleaning of the suction pipe 120, which can meet the various usage needs of consumers.

[0315] A seventh aspect of this application provides a control method for a cleaning device 100, which can be a floor scrubber, vacuum cleaner, sweeping robot, etc., capable of cleaning dirt in an area to be cleaned. The cleaning device 100 includes a suction pipe 120 and a functional component 190, the transmitting end of which is connected to the cavity 120a of the suction pipe 120. The installation position, installation posture, and connection structure of the functional component 190 on the suction pipe 120 can be found in the description of the functional component 190 in the second aspect of this application, and will not be repeated here. Other undescribed aspects of the cleaning device 100 can be found in the description of the cleaning device 100 in the third aspect of this application, and will not be repeated here.

[0316] The cleaning device 100 has a drying mode, in which the suction pipe 120 is dried. (See also...) Figure 27 The corresponding control methods include the following:

[0317] Step 4051: In response to the drying command, control the cleaning equipment 100 to enter the drying mode.

[0318] Step 4052: In drying mode, the suction power element is controlled to operate to form an airflow within the suction pipe 120. Additionally, the control function element 190 outputs a disinfection medium into the cavity 120a of the suction pipe 120.

[0319] In some embodiments, the disinfection medium has at least one of the functions of sterilization, disinfection, and deodorization. In some embodiments, the disinfection medium is at least one of negative ions, ultraviolet light, plasma, and ozone. Correspondingly, the functional component 190 can be at least one of a negative ion generator, an ultraviolet light source, a plasma electrode, and an ozone generator.

[0320] As the functional component 190 outputs the disinfection medium, airflow is already formed in the suction pipe 120. Therefore, the disinfection medium output by the functional component 190 collides with the airflow, causing turbulence. In this turbulent environment, the disinfection medium comes into full contact with bacteria, viruses, harmful substances, and odors in the airflow, eliminating them to a certain extent and purifying and disinfecting the suction pipe 120. When the disinfection medium enters the sludge collection box of the cleaning equipment 100 with the airflow, the remaining disinfection medium continues to eliminate bacteria, viruses, harmful substances, and odors, purifying and disinfecting the sludge collection box. Furthermore, the disinfection medium also comes into contact with the filter element with the airflow, further purifying and disinfecting the sludge collection box.

[0321] Please combine Figure 28 Prior to responding to the drying command in step 4051, the control method further includes the following steps:

[0322] Step 4041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0323] Specifically, the generation / triggering method of the self-cleaning instruction can be referred to the relevant introduction of the self-cleaning instruction in the fifth aspect embodiment above, and will not be repeated here.

[0324] When the cleaning equipment 100 enters the self-cleaning mode, it primarily performs self-cleaning of the cleaning component 160 and / or the suction pipe 120. Wastewater generated during the self-cleaning process of the cleaning component 160 enters the suction pipe 120; therefore, after the cleaning component 160 self-cleans, the suction pipe 120 must also self-clean. For more specific details regarding the self-cleaning mode of the cleaning equipment 100, please refer to the relevant descriptions of the self-cleaning modes in the fifth and sixth aspects of the embodiments described above, which will not be repeated here.

[0325] In some embodiments, the cleaning device 100 enters a self-cleaning mode, specifically including: controlling the pump 131 to continuously supply liquid to the cleaning component 160, and controlling the operation of the suction power element so that the wastewater generated by the self-cleaning of the cleaning component 160 is sucked into the suction pipe 120 and eventually enters the collection tank.

[0326] In the initial stage of self-cleaning mode, the liquid supplied by pump 131 primarily cleans the cleaning component 160, and the wastewater generated by the self-cleaning of the cleaning component 160 is drawn into the suction pipe 120. Dust particles in the wastewater will soil the inner wall of the suction pipe 120. As the cleaning component 160 self-cleans, it gradually becomes cleaner, and the water flowing into the suction pipe 120 is then cleaner enough to clean the inner wall of the suction pipe 120, which is the self-cleaning stage of the suction pipe 120.

[0327] In other embodiments, the cleaning device 100 enters a self-cleaning mode, specifically including controlling the nozzle 150 to provide a cleaning medium to the cavity 120a of the suction pipe 120. That is, the functional component 190 and the nozzle 150 are installed on the pipe wall 121 of the suction pipe 120, and the self-cleaning of the suction pipe 120 is achieved by the nozzle 150 spraying liquid. This avoids wetting the cleaning component 160 during the self-cleaning stage of the suction pipe 120, and the direct rinsing of the suction pipe 120 by the nozzle 150 results in a better cleaning effect.

[0328] In some embodiments, the control of the nozzle 150 to provide cleaning medium to the cavity 120a of the suction pipe 120 can be performed by controlling the pump 131 to pump liquid to the nozzle 150 by continuous operation, so that the nozzle 150 uses the liquid to spray cleaning medium into the cavity 120a of the suction pipe 120.

[0329] It is understood that the pump 131 that performs the self-cleaning stage of the suction pipe 120 and the pump 131 that performs the self-cleaning stage of the cleaning component 160 can be the same pump or different pumps, and this application does not impose any restrictions.

[0330] Step 4042: Self-cleaning mode ends, generating drying command.

[0331] In some embodiments, the degree of dirtiness of the liquid output from the suction pipe 120 to the collection tank can be used to determine whether the self-cleaning mode has ended. For example, if the degree of dirtiness of the liquid output from the suction pipe 120 to the collection tank is less than a set condition, the self-cleaning mode is determined to have ended. In some embodiments, the self-cleaning mode time can also be set, and the self-cleaning mode is determined to have ended after the set duration has elapsed.

[0332] Please see Figure 29 The diagram shows a flowchart of a control method for a cleaning device 100 in some other embodiments of this application. The control method includes the following steps:

[0333] Step 401: In response to the work instruction, acquire the detection signal of the ground type of the area to be cleaned.

[0334] Step 402: Determine the ground type of the area to be cleaned based on the detection signal. Step 302 specifically includes:

[0335] If the floor type of the area to be cleaned indicated by the detection signal is the first type, a vacuuming command is generated. If the floor type of the area to be cleaned indicated by the detection signal is the second type, a floor washing command is generated.

[0336] Step 403: In response to the generated instructions, perform the corresponding cleaning operation. Step 303 specifically includes:

[0337] Step 4031A: In response to the vacuuming command, control the cleaning device 100 to enter the vacuuming mode.

[0338] Step 4032A: In vacuum mode, control the operation of the suction power unit to draw dirt from the area to be cleaned into the suction pipe 120. Control the nozzle 150 to supply liquid medium to the cavity 120a of the suction pipe 120.

[0339] Step 4031B: In response to the floor washing command, control the cleaning equipment 100 to enter the floor washing mode.

[0340] Step 4032B: In the floor cleaning mode, control pump 131 pumps liquid to distributor 136 so that cleaning component 160 uses the liquid output from distributor 136 to perform wet cleaning of the area to be cleaned.

[0341] Step 4033: Vacuuming mode / floor washing mode ends, generating self-cleaning command.

[0342] Step 4041: In response to the self-cleaning command, control the cleaning device 100 to enter the self-cleaning mode.

[0343] Step 4042: Self-cleaning mode ends, generating drying command.

[0344] Step 4051: In response to the drying command, control the cleaning equipment 100 to enter the drying mode.

[0345] Step 4052: In drying mode, the suction power element is controlled to operate to form an airflow within the suction pipe 120. Additionally, the control function element 190 outputs a disinfection medium into the cavity 120a of the suction pipe 120.
