Description

Technical Field

[0001] This application belongs to the field of cleaning technology, and specifically provides a self-cleaning method for a surface cleaning system. Background Technology

[0002] As people's living standards improve, various electric surface cleaning devices are gradually entering people's daily lives. These devices feature a mop driven by a motor, making cleaning easier for users. Some existing surface cleaning devices also include a cleaning assembly with a cleaning tank and a collection chamber. When the mop needs cleaning, the user places the surface cleaning device on the cleaning assembly, placing the mop in the cleaning tank filled with cleaning fluid. The mop rotates within the tank to complete the cleaning process. After a period of cleaning, the cleaning assembly will sound an alarm to prompt the user to press a pedal to drain the wastewater from the cleaning tank into the collection chamber, allowing the mop to dry completely within the tank.

[0003] However, after finishing the cleaning work, users place the surface cleaning device on the cleaning assembly, activate the self-cleaning function, and then go to another room to rest. Existing products, on the one hand, set the mop's rotation speed very fast during cleaning to improve the cleaning effect, and on the other hand, to prevent the alarm sound from being too loud and affecting the user experience, they did not consider the impact of the mop's rotation cleaning sound on the alarm sound. As a result, the sound of the mop cleaning can drown out the alarm sound. This means that when the alarm sounds, users in other rooms cannot hear it. As a result, the mop drying step is also carried out in the cleaning solution, which means it is not actually dried. On the one hand, the mop is left damp and is prone to mold. On the other hand, users may need to squeeze out the water from the mop again before the next use, which increases the user's workload. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this application provides a self-cleaning method for a surface cleaning system. The surface cleaning system includes a surface cleaning device and a cleaning assembly. The surface cleaning device is equipped with a mopping component, and the cleaning assembly includes a cleaning tank for containing the mopping component and cleaning fluid, as well as a dirt collection chamber. The surface cleaning system also includes a sound-generating device. The self-cleaning method includes:

[0005] Docking steps: Connect the surface cleaning device and the cleaning components to ensure that the mop is positioned in the cleaning tank;

[0006] Cleaning steps: Rotate the mop / wiper in the cleaning tank for cleaning;

[0007] Prompt step: The sound-generating device operates and reduces the rotation speed of the mopping component to a preset speed n, where the preset speed n is less than any speed in the cleaning step.

[0008] Optionally, in the cleaning step, the mopping component is switched from a first rotational speed N1 to a second rotational speed N2, where the second rotational speed N2 is greater than the first rotational speed N1.

[0009] Optionally, the ratio of the preset rotational speed n to the first rotational speed N1 is less than 1 / 2.

[0010] Optionally, during the cleaning process, the mop is stopped rotating at set intervals t1 and restarted after a stop time t2.

[0011] Optionally, the stopping time t2 is less than 5 seconds.

[0012] Optionally, the switching method for the rotation speed of the wiping component includes:

[0013] The voltage of the drive motor of the wiping component is changed in a stepwise manner to alter the rotational speed of the wiping component; or,

[0014] The voltage of the drive motor of the wiping component is continuously varied to change the rotational speed of the wiping component.

[0015] Optionally, the surface cleaning device further includes a dirt collection box and a scraper, the scraper being used to scrape off dirt from the mop, the dirt collection box being provided with a drain outlet and a valve for controlling the opening and closing of the drain outlet, and the self-cleaning method further includes:

[0016] Valve opening procedure: Open the valve to connect the sludge collection box and the sludge collection chamber through the drain port.

[0017] Optionally, the self-cleaning method further includes:

[0018] Judgment Step: Determine whether the surface cleaning device is in an upright state. If yes, start the cleaning step; if no, end the self-cleaning process.

[0019] Optionally, during the cleaning step, the rotational speed of the mopping component increases and decreases at both times to disturb the water flow.

[0020] Optionally, the sound-generating device is a buzzer or a voice prompt element, and the ratio of the preset rotation speed n to the first rotation speed N1 is greater than 1 / 4.

[0021] Those skilled in the art will understand that the self-cleaning method of the surface cleaning system described above in this application has at least the following beneficial effects:

[0022] 1. By reducing the rotation speed of the mop to a preset speed n when the generating device is working, and ensuring that the preset speed n is less than any speed during the cleaning process, the mop can rotate at a high speed during cleaning to ensure the cleaning effect. When the sound-generating device is working, the rotation speed of the mop decreases, reducing the sound emitted by the mop rotating in the cleaning tank. This prevents the sound of the mop rotating from drowning out the alarm sound of the sound-generating device, allowing users who are far from the cleaning components or in other rooms to hear the alarm sound more clearly. Thus, while ensuring the cleaning effect of the mop, users can receive timely information to drain the wastewater in the cleaning tank into the collection chamber, so that the mop can be dried. This prevents the mop from being left damp and makes it easier for users to use it next time, improving the user experience.

[0023] 2. By switching the mop from a lower first speed N1 to a higher second speed N2 during the cleaning step, the mop can first be cleaned at a low speed to wash off the dirt attached to its surface, and then cleaned at a high speed to ensure the cleaning effect of the mop. This avoids the mop from throwing off the dirt attached to its surface from the cleaning component when using a high speed to clean from the beginning, while ensuring the cleaning effect.

[0024] Furthermore, by making the ratio of the preset rotation speed n to the first rotation speed N1 less than 1 / 2, the difference between the preset rotation speed n and the rotation speed in the cleaning step is large enough, so that the sound of the sound-generating device can be better highlighted.

[0025] 3. By stopping the mop at set intervals t1, the cleaning fluid in the cleaning tank can impact the mop when it stops, improving the rinsing effect of the cleaning fluid. At the same time, the impact of the cleaning fluid on the mop also helps to unfold the fibers of the mop, improving the cleaning effect on the inner layer of the fibers, thus improving the cleaning effect of the mop. On the other hand, when the mop stops for a period of time, the dirt in the cleaning fluid can settle, so when the mop starts to rotate again, the cleaning fluid in contact with the mop is cleaner.

[0026] Furthermore, by keeping the stop time t2 less than 5 seconds, the cleaning time of the mop is avoided from being excessively prolonged.

[0027] 4. By setting a drain port and a valve for controlling the opening and closing of the drain port in the sludge collection box, after the surface cleaning device is placed on the cleaning assembly, the opened valve connects the sludge collection box and the sludge collection chamber through the drain port. At this time, the mop rotates in the cleaning tank containing cleaning liquid. The scraper can squeeze the rotating mop to squeeze out the liquid absorbed by the mop and let it fall into the sludge collection box. Because the mop increases from a lower first speed N1 to a second speed N2, the landing point of the liquid squeezed out by the scraper in the sludge collection box also changes, thereby cleaning different areas of the sludge collection box. This allows the mop to achieve self-cleaning in the cleaning tank and also achieves self-cleaning of the sludge collection box, reducing the user's cleaning work and improving the user experience.

[0028] 5. By checking whether the surface cleaning device is in an upright position before starting the cleaning step, the stability of the surface cleaning device placed on the cleaning component can be guaranteed, and the surface cleaning device can be prevented from tipping over due to vibration during the cleaning process.

[0029] 6. By alternating the rotation speed of the mop during cleaning (both increasing and decreasing), the water flow is disturbed, thus improving the cleaning effect of the water flow on the mop.

[0030] 7. By setting the sound-generating device as a buzzer or voice prompt element, and making the ratio of the preset rotation speed n to N1 greater than 1 / 4, the sound of the buzzer or voice prompt element is not loud. In particular, the sound of the voice prompt element is transmitted through the housing of the surface cleaning device. If the rotation speed is not reduced enough, the sound of the voice prompt cannot drown out the noise generated by the rotating cleaning component during the cleaning process. Therefore, the customer will still have difficulty hearing the prompt immediately. In addition, the mop component is kept running at a low speed when the device is working. This prevents the mop component from stopping, so that the rotation sound of the mop component does not drown out the sound of the sound-generating device. The mop component can keep rotating, which makes it easy for the mop component to increase its speed again. This facilitates the discharge of dirt after self-cleaning and will not affect the effect and efficiency of self-cleaning. Attached Figure Description

[0042] Those skilled in the art should understand that the embodiments described below are merely a part of the embodiments of this application, and not all of the embodiments of this application. These partial embodiments are intended to explain the technical principles of this application and are not intended to limit the scope of protection of this application. Based on the embodiments provided in this application, all other embodiments obtained by those skilled in the art without creative effort should still fall within the scope of protection of this application.

[0043] It should be noted that in the description of this application, terms such as "center," "upper," "lower," "top," "bottom," "left," "right," "vertical," "horizontal," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Furthermore, it should be noted that, in the description of this application, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can also refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0045] The surface cleaning system of this application includes a surface cleaning device and a cleaning assembly. The surface cleaning device is equipped with a mopping component, and the cleaning assembly is equipped with a cleaning tank for containing the mopping component and cleaning fluid, as well as a dirt collection chamber. The surface cleaning system is equipped with a sound-generating device. The self-cleaning method of this application includes:

[0046] Docking steps: Connect the surface cleaning device and the cleaning components to ensure that the mop is positioned in the cleaning tank;

[0047] Cleaning steps: Rotate the mop / wiper in the cleaning tank for cleaning;

[0048] Prompt step: The sound-generating device operates and reduces the rotation speed of the mopping component to a preset speed n, where the preset speed n is less than any speed in the cleaning step.

[0049] The self-cleaning method of this application reduces the rotation speed of the mop to a preset speed n when the generating device is working, and makes the preset speed n less than any speed in the cleaning step. This allows the mop to rotate at a high speed during the cleaning process to ensure the cleaning effect. When the sound generating device is working, the rotation speed of the mop decreases, reducing the sound emitted by the mop rotating in the cleaning tank. This prevents the sound of the mop rotating from drowning out the alarm sound of the sound generating device, allowing users who are far away from the cleaning components or in other rooms to hear the alarm sound more clearly. Thus, while ensuring the cleaning effect of the mop, it also allows users to receive timely information to drain the wastewater in the cleaning tank into the collection chamber, so that the mop can be dried. This avoids the mop being left damp and makes it easier for users to use it next time, improving the user experience.

[0050] The self-cleaning method of this application will be further described below with reference to the accompanying drawings.

[0051] First embodiment of this application:

[0052] like Figures 1 to 4As shown, the surface cleaning system of this embodiment includes a surface cleaning device 1 and a cleaning assembly 2. The surface cleaning device 1 includes a cleaning head 11, a body 12, cleaning rollers 13 serving as wiping elements, and a dirt collection box 14. The body 12 is pivotally connected to the cleaning head 11 and has a handle for the user to hold, allowing the user to control the movement of the surface cleaning device 1. Two cleaning rollers 13 are provided, respectively located at the front and rear ends of the cleaning head 11, and are pivotally connected to the cleaning head 11. The surface cleaning device 1 is equipped with a drive motor to drive the cleaning rollers 13 to rotate, and the rotating cleaning rollers 13 can clean the surface to be cleaned. The cleaning head 11 has two scraping elements 111, which correspond to the two cleaning rollers 13 respectively, thereby scraping and squeezing the two cleaning rollers 13. The dirt squeezed out by the scraping elements 111 falls into the dirt collection box 14, which has two drainage portions 141 that respectively fit against the two cleaning rollers 13 to prevent dirt from flowing out.

[0053] It should be noted that the scraping part 111 may be omitted, and the cleaning roller 13 may be scraped directly by the drainage part 141 of the dirt collection box 14.

[0054] Continue to refer to Figures 1 to 4 As shown, the sludge collection box 14 is further provided with a drain port 142 and a valve 143. An elastic member (such as a torsion spring, tension spring, or spring sheet) is provided between the valve 143 and the sludge collection box 14. The elastic member is used to keep the valve 143 in the position of closing the drain port 142. The cleaning assembly 2 is provided with a cleaning tank 21, a sludge collection chamber 22, a drive unit 23, and a pedal 24. The drive unit 23 is a top column. After the surface cleaning device 1 is placed on the cleaning assembly 2, the two cleaning rollers 13 are respectively accommodated by the two cleaning tanks 21. The cleaning tanks 21 are provided with scraping ribs (not shown in the figure) for contacting the cleaning rollers 13. The drive unit 23 abuts against the valve 143, thereby overcoming the elastic force of the elastic member to open the drain port 142, so that the sludge collection box 14 and the sludge collection chamber 22 are connected through the drain port 142. The cleaning roller 13 rotates and cleans in the cleaning tank 21. The scraper 111 scrapes the cleaning roller 13, causing the liquid flow to enter the sludge collection box 14 and then the sludge collection chamber 22 through the drain port 142. A connecting hole (not shown in the figure) and a seal (not shown in the figure) are provided between the cleaning tank 21 and the sludge collection chamber 22. When the pedal 24 is pressed, the seal opens the connecting hole, and the cleaning tank 21 communicates with the sludge collection chamber 22. The surface cleaning device 1 or the cleaning assembly 2 is equipped with a sound-emitting device (not shown in the figure) to emit an alarm sound.

[0055] Combination Figure 5 As shown, the cleaning method in this embodiment includes:

[0056] Docking steps: Connect the surface cleaning device and the cleaning components so that the cleaning roller is located in the cleaning tank.

[0057] Specifically, the user places the surface cleaning device 1 on the cleaning assembly 2, aligning the two in place, and places the cleaning roller 13 in the cleaning tank 21 to contact the cleaning liquid in the cleaning tank 21.

[0058] Valve opening procedure: Open the valve to connect the sludge collection box and the sludge collection chamber through the drain port.

[0059] Specifically, after the surface cleaning device 1 is placed on the cleaning assembly 2, the drive unit 23 abuts against the valve 143, causing the valve 143 to open the drain port 142.

[0060] It should be noted that an electric valve can also be installed in the sludge collection box 14, and the opening and closing of the electric valve can be controlled by the control module.

[0061] Cleaning steps: Rotate the cleaning roller in the cleaning tank to clean.

[0062] Specifically, the cleaning roller 13 rotates under the drive of the drive motor, wherein the cleaning roller 13 on the front side of the cleaning head 11 rotates counterclockwise (e.g., Figure 3 and Figure 4 As shown by the dashed arrow, the cleaning roller 13 on the rear side of the cleaning head 11 rotates clockwise (as shown by the dashed arrow). Figure 3 and Figure 4 (As indicated by the dashed arrow).

[0063] Furthermore, in this step, the rotational speed of the cleaning roller 13 is switched from a lower first rotational speed N1 to a higher second rotational speed N2, wherein:

[0064] As an example: Combining Figure 6 As shown, the voltage of the drive motor changes in a stepped manner, causing the cleaning roller 13 to rotate from a lower first speed N1 to a higher second speed N2. Specifically, the voltage of the drive motor is first maintained at the voltage value that allows the cleaning roller 13 to rotate at the first speed N1. After maintaining this voltage for a period of time, the voltage of the drive motor is increased to another voltage value and maintained for a period of time, thereby increasing the speed of the cleaning roller 13 until the voltage of the drive motor is maintained at the voltage value that allows the cleaning roller 13 to rotate at the second speed N2, thus keeping the cleaning roller 13 rotating at the second speed N2. During this period, the scraping member 111 scrapes and squeezes the cleaning roller 13, which can squeeze out the liquid absorbed by the cleaning roller 13 and block the water flow driven by the cleaning roller 13, such as... Figure 4 As shown by the solid arrow, when the cleaning roller 13 rotates at a low speed, the scraped and deflected liquid flows are farther from the discharge port 142 at the point of impact in the collection box 14. Figure 5 As shown by the solid arrow, when the cleaning roller 13 rotates at a relatively high speed, the liquid that is scraped out and blocked falls directly into the sludge collection box 14, and the point of impact is closer to the drain outlet 142.

[0065] It should be noted that the voltage of the drive motor can vary in a uniform stepwise manner or in a non-uniform stepwise manner, such as making the lower voltage last for a longer period of time, or making the higher voltage last for a longer period of time. In other words, the duration of each rotational speed can be different during the variation process.

[0066] As an example two: Combining Figure 7 As shown, the voltage of the drive motor changes continuously, causing the cleaning roller 13 to rotate from a lower first speed N1 to a higher second speed N2. Specifically, the voltage of the drive motor is first maintained at the voltage value that causes the cleaning roller 13 to rotate at the first speed N1. After maintaining this voltage for a period of time, the voltage of the drive motor is continuously increased until it is maintained at the voltage value that causes the cleaning roller 13 to rotate at the second speed N2, so that the cleaning roller 13 continues to rotate at the second speed N2.

[0067] It should be noted that the voltage rise or fall portion of the image can have a constant slope or a changing slope, such as making the image of the low voltage portion smoother or the image of the high voltage portion smoother.

[0068] Prompt steps: Activate the sound-generating device and reduce the rotational speed of the cleaning roller to a preset speed n, where the preset speed n is less than any speed in the cleaning step.

[0069] Specifically, after the cleaning roller 13 has been cleaning for a certain period of time, the user needs to step on the pedal 24 to discharge the sewage in the cleaning tank 21 into the collection chamber 22. Therefore, the generating device is activated to remind the user and to reduce the rotation speed of the cleaning roller 13 to a preset speed n. The preset speed n is less than any speed in the cleaning step, that is, the preset speed n is less than the first speed N1 in the cleaning step.

[0070] It should be noted that the sound-generating device can be a buzzer or a voice prompt element.

[0071] Those skilled in the art will understand that the self-cleaning method of this embodiment reduces the rotational speed of the cleaning roller 13 to a preset speed n when the generating device is working, and makes the preset speed n less than the speed in the cleaning step. This allows the cleaning roller 13 to rotate at a high speed during the cleaning process to ensure the cleaning effect of the cleaning roller 13. When the sound generating device is working, the rotational speed of the cleaning roller 13 decreases, reducing the sound emitted by the cleaning roller 13 rotating in the cleaning tank 21. This prevents the sound of the cleaning roller 13 rotating from drowning out the alarm sound of the sound generating device, allowing users who are far away from the cleaning component 2 or in other rooms to hear the alarm sound more clearly. Thus, while ensuring the cleaning effect of the cleaning roller 13, it also allows users to receive timely information to discharge the wastewater in the cleaning tank 21 into the collection chamber 22, so that the cleaning roller 13 can be dried. This prevents the cleaning roller 13 from being placed damp and facilitates the user's next use, improving the user experience.

[0072] Furthermore, by switching the cleaning roller 13 from a lower first speed N1 to a higher second speed N2 during the cleaning step, the cleaning roller 13 can first be cleaned at a low speed to wash off the dirt adhering to its surface, and then cleaned at a high speed to ensure the cleaning effect of the cleaning roller 13. This avoids the cleaning roller 13 throwing off the dirt adhering to its surface due to the high speed cleaning at the beginning. In addition, during the cleaning process, the scraper 111 scrapes and squeezes the rotating cleaning roller 13, squeezing out the liquid absorbed by the cleaning roller 13 and causing it to fall into the sludge collection box 14. Because the cleaning roller 13 increases from the lower first speed N1 to the second speed N2, the landing point of the liquid squeezed by the scraper 111 in the sludge collection box 14 also changes, thereby cleaning different areas of the sludge collection box 14. This allows the cleaning roller 13 to achieve self-cleaning in the cleaning tank 21 and also achieves self-cleaning of the sludge collection box 14, reducing the user's cleaning work and improving the user experience.

[0073] The self-cleaning method of this embodiment will be illustrated below with an example:

[0074] The first rotational speed N1 is 150 rpm, and the second rotational speed N2 is 400 rpm. In the cleaning step, the cleaning roller 13 first rotates at 150 rpm for 40 seconds, then increases to 260 rpm for 40 seconds, and then increases to 400 rpm for 40 seconds, thus completing the switch from the first rotational speed N1 to the second rotational speed N2. After the cleaning roller 13 rotates at 400 rpm for 40 seconds, the sound-emitting device works and emits an alarm sound. At this time, the rotational speed of the cleaning roller 13 drops to 50 rpm.

[0075] In this embodiment, preferably, the preset rotational speed n is equal to one-third of the first rotational speed N1, so that the difference between the preset rotational speed n and the rotational speed during the cleaning step is large enough, thereby allowing the sound from the sound-generating device to be better highlighted. Furthermore, keeping the cleaning roller 13 running at a low speed while the sound-generating device is operating serves two purposes: firstly, to prevent the cleaning roller 13 from stopping, ensuring that the sound of the cleaning roller 13's rotation does not drown out the sound from the sound-generating device; and secondly, to allow the cleaning roller 13 to continue rotating, facilitating the increase in rotational speed after self-cleaning, and ensuring proper waste removal without affecting the self-cleaning effect and efficiency.

[0076] It should be noted that the preset rotational speed n can be less than 1 / 2 of the first rotational speed N1 and greater than 1 / 4.

[0077] In this embodiment, preferably, the preset rotational speed n is greater than 0. In other words, the rotational speed of the cleaning roller 13 decreases, but does not stop rotating. That is, it maintains rotation at a low speed, so that the rotational sound of the cleaning roller 13 does not drown out the sound of the sound-generating device. The cleaning roller 13 can continue to rotate, making it easier for the cleaning roller 13 to increase its rotational speed again.

[0078] It should be noted that the cleaning roller 13 can also stop rotating during the prompting steps, that is, the preset rotation speed n is 0.

[0079] As an example of the cleaning step, in the cleaning step, the cleaning roller 13 stops rotating at a set time t1, and restarts after a stop time t2. In other words, the drive motor stops working at a set time t1, thereby stopping the cleaning roller 13, and after a time t2, the drive motor restarts to make the cleaning roller 13 rotate again.

[0080] Those skilled in the art will understand that by stopping the cleaning roller 13 at set intervals t1, on the one hand, the cleaning fluid in the cleaning tank can impact the cleaning roller 13 when it stops, thereby improving the rinsing effect of the cleaning fluid on the cleaning roller 13. At the same time, the impact of the cleaning fluid on the cleaning roller 13 also helps to unfold the fibers of the cleaning roller 13, improving the cleaning effect on the inner layer of the fibers, thus helping to improve the cleaning effect of the cleaning roller 13. On the other hand, when the cleaning roller 13 stops for a period of time, the dirt in the cleaning fluid can settle, and when the cleaning roller 13 rotates again, the cleaning fluid in contact with the cleaning roller 13 is cleaner.

[0081] Specifically, time t1 can be 5 seconds, 10 seconds, 20 seconds, etc., which can be selected by the user according to their needs. Preferably, time t2 is less than 5 seconds, such as 2 seconds, 3.5 seconds, etc., to avoid excessively prolonging the cleaning time of cleaning roller 13.

[0082] As an example of the cleaning process, during the cleaning process of the cleaning roller 13, the rotation speed of the cleaning roller 13 has both an increasing and decreasing process, that is, the rotation speed of the cleaning roller 13 alternates between fast and slow, instead of switching from the first rotation speed N1 to the second rotation speed N2 in a continuous upward motion. This can cause disturbance in the water flow and improve the cleaning effect of the water flow on the cleaning roller 13.

[0083] The second embodiment of this application:

[0084] like Figure 8 As shown, the self-cleaning method of this application includes:

[0085] Docking steps: Connect the surface cleaning device and the cleaning components to ensure that the mop is positioned in the cleaning tank;

[0086] Cleaning steps: Rotate the mop / wiper in the cleaning tank for cleaning;

[0087] Prompt step: The sound-generating device operates and reduces the rotation speed of the mopping component to a preset speed n, where the preset speed n is less than any speed in the cleaning step.

[0088] Specifically, unlike the first embodiment, the surface cleaning device in this embodiment does not have a sludge collection box, so there is no need to clean the sludge collection box.

[0089] It should be noted that the mopping component in this embodiment can be a cleaning roller or a rotary mop.

[0090] The third embodiment of this application:

[0091] Although not shown in the figure, unlike the second embodiment, in the cleaning step of this embodiment, the cleaning roller is kept rotating at a high speed, for example, at 400 revolutions per minute. Alternatively, it can rotate at alternating high and low speeds, for example, alternating between 400 revolutions per minute and 200 revolutions per minute.

[0092] The fourth embodiment of this application:

[0093] Although not shown in the figure, unlike the previous embodiments, the self-cleaning method in this embodiment also includes a judgment step before the cleaning step:

[0094] Determine if the surface cleaning device is in an upright position. If yes, start the cleaning step; otherwise, end the self-cleaning process.

[0095] Specifically, a triggering device is provided at the connection between the body and the cleaning head. The triggering device between the body and the cleaning head is only triggered when the body is in an upright position. At this time, the user can turn on the surface cleaning device to start self-cleaning. Otherwise, the user cannot start the surface cleaning device, thereby ensuring the stability of the surface cleaning device placed on the cleaning component and preventing the surface cleaning device from tipping over due to vibration during the cleaning process.

[0096] The technical solutions of this application have been described in conjunction with the preceding embodiments. However, it will be readily understood by those skilled in the art that the scope of protection of this application is not limited to these specific embodiments. Without departing from the technical principles of this application, those skilled in the art can disassemble and combine the technical solutions in the above embodiments, and can also make equivalent changes or substitutions to the relevant technical features. Any changes, equivalent substitutions, improvements, etc., made within the technical concept and / or technical principles of this application will fall within the scope of protection of this application.
