Description

Technical Field

[0001] The present application relates to the technical field of cleaning equipment, and in particular to a cleaning equipment and a cleaning system. Background Art

[0002] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor scrubbers have greatly reduced the labor intensity and time spent on housework due to their high mopping efficiency and convenience, and are becoming more and more popular among users.

[0003] Compared with traditional dry vacuum cleaners, floor scrubbers are larger in size due to the addition of components such as a clean water tank and a dirty water tank. When laid flat, the overall height of the machine body is high. When encountering relatively low and narrow areas to be cleaned, such as under sofas, beds, and cabinet legs, the floor brush and the main machine body cannot be fully extended into the area to be cleaned to complete the cleaning, resulting in a dead spot in the cleaning of the equipment, affecting the cleaning effect. Summary of the invention

[0004] The present application provides a cleaning device and a cleaning system, the body of which can enter a relatively low and narrow space for cleaning, thereby avoiding the existence of cleaning dead zones and improving the cleaning effect.

[0005] The first aspect of the present application provides a cleaning device, comprising: a floor brush assembly, for cleaning a surface to be cleaned; a clean water tank, the clean water tank being arranged on the floor brush assembly and being used to supply water to the floor brush assembly; a body, the body being rotatably connected to the floor brush assembly so that the body can rotate relative to the floor brush assembly between an upright position and a flat position; wherein, when the body is in the flat position, the angle between the body and the surface to be cleaned is 175°-180°; a sewage tank, the sewage tank being arranged on the body and being connected to the floor brush assembly; a power device, being arranged on the body and being connected to the sewage tank, the power device being at least used to suck dirt at the floor brush assembly into the sewage tank; the power device being configured such that the suction power when the body is in the flat position is lower than the suction power when the body is in the upright position; when the body is in the flat position, in the height direction, the highest point of the cleaning device is formed on the mating portion between the sewage tank and the power device, and the distance between the highest point and the surface to be cleaned is 90mm-130mm.

[0006] According to the cleaning equipment of the present application, when the body is in the lying position, the highest point is formed on the matching part between the sewage tank and the power device of the cleaning equipment, so that the highest point of the cleaning equipment in the lying position can be away from the floor brush assembly, and the length of the cleaning equipment entering the low area can be increased. In addition, considering the volume of the sewage tank on the cleaning equipment and the height of the low area that can be entered, the present application sets the distance between the highest point of the cleaning equipment in the lying position and the surface to be cleaned to 90mm-130mm; wherein, the height of the body of the cleaning equipment in the lying position does not exceed 130mm, so that the body can completely enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect; at the same time, the height of the body in the lying position is not less than 90mm, which can ensure the volume of the sewage tank when the body enters a relatively low area, and improve the cleaning efficiency of the cleaning equipment; to avoid the situation where the volume of the sewage tank is too small due to the thin body, thereby affecting the cleaning efficiency. Moreover, since the power unit is configured so that the suction power when the fuselage is in a lying position is lower than the suction power when the fuselage is in an upright position, even if the height of the power unit compared to the sewage tank is lowered due to the fuselage being in a lying position, water vapor can be avoided from being sucked into the power unit, thereby ensuring that the power unit can work normally when the fuselage is in a lying position, so as to better clean low and narrow spaces.

[0007] In some embodiments, the fuselage includes a casing, the casing includes a supporting portion and the matching portion, the supporting portion and the matching portion together enclose an accommodating space, the sewage tank is arranged in the accommodating space, and the power device is arranged on a side of the matching portion away from the sewage tank; when the fuselage is in the lying position, in the height direction, the total thickness of the matching portion and the supporting portion is 90mm-130mm.

[0008] Since the parts of the fuselage corresponding to the power device and the sewage tank are parts of the fuselage with relatively large thickness, the matching part is between the power device and the sewage tank, which not only allows a smooth transition between the sewage tank and the power device, but also sets the highest point of the cleaning device on the side surface of the matching part facing away from the support part when the fuselage is in a flat position, which can increase the thickness of the sewage tank on the side close to the matching part, and further increase the volume of the sewage tank. In this embodiment, the total thickness of the matching part and the support part is set to 90mm-130mm, which can ensure that the fuselage can fully enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect, and can also avoid the situation where the highest point is too low, resulting in a small volume of the sewage tank, which affects the cleaning efficiency.

[0009] In some embodiments, the thickness of the sewage tank when the body is in the lying position ranges from 107 mm to 125 mm.

[0010] In this way, on the one hand, the thickness of the sewage tank can be guaranteed, and then the volume of the sewage tank can be guaranteed, further improving the cleaning efficiency. And it can avoid the problem that the effective volume of the sewage tank is small due to the thickness of the sewage tank being too small, so that the cleaning equipment needs to clean the sewage tank frequently, and the cleaning efficiency of the cleaning equipment is low. On the other hand, it can avoid the excessive thickness of the sewage tank, which leads to the excessive thickness of the fuselage when it is lying flat, and then the fuselage cannot enter the relatively low area. And when the total thickness of the fuselage is constant, it can avoid the problem that the thickness of the sewage tank is too large, resulting in the thickness of the support part opposite to the sewage tank being too small, so that the structural strength and stability of the support part are reduced, and then the strength of the fuselage is reduced.

[0011] In some embodiments, the thickness of the support portion when the body is in the lying flat position ranges from 5 mm to 23 mm.

[0012] In this way, on the one hand, setting the thickness to be above 5 mm can avoid the thickness of the support part being too small, which will reduce the structural strength and stability of the support part, and is not conducive to the better installation of other functional components of the cleaning equipment such as the sewage tank and the power device. On the other hand, setting the thickness to be below 23 mm can avoid the thickness of the support part being too large, occupying too much space in the fuselage, resulting in a smaller space for accommodating the sewage tank, resulting in a smaller effective volume of the sewage tank, and requiring the cleaning equipment to frequently return to the cleaning base station for self-cleaning, which makes the cleaning efficiency of the cleaning equipment low.

[0013] In some embodiments, when the body is in the lying position, the thickness of the matching portion on a side close to the sewage tank ranges from 107 mm to 125 mm.

[0014] In this way, the thickness of the matching part close to the sewage tank is set to 107mm-125mm, which can provide a larger accommodating space for the sewage tank, thereby ensuring the volume of the sewage tank. The position of the matching part close to the sewage tank is flush with the outer surface of the sewage tank, and the position of the matching part close to the sewage tank constitutes the highest point of the body in the lying position, which can ensure that the body can fully enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect, and can also avoid the highest point being too low, resulting in a small volume of the sewage tank, which affects the cleaning efficiency.

[0015] In some embodiments, when there is a target obstacle on the surface to be cleaned and there is a cleaning gap in the height direction between the target obstacle and the surface to be cleaned, the height of the cleaning gap is 100-170 mm, and when the floor brush assembly enters the cleaning gap and the body is in the lying position, the distance between the highest point and the top wall of the cleaning gap is 10-80 mm.

[0016] In this way, on the one hand, collision or interference between the highest point of the fuselage and the top wall of the cleaning gap is avoided, so that the fuselage can completely enter the low cleaning gap within 100-170mm for cleaning, avoiding the existence of cleaning dead zones, improving cleaning effects, and improving user experience; on the other hand, while ensuring that the fuselage can enter the cleaning gap, the thickness of the sewage tank can be increased as much as possible, thereby increasing the effective volume of the sewage tank, which helps to reduce the frequency of the cleaning equipment returning to the cleaning base station for self-cleaning, thereby improving cleaning efficiency.

[0017] In some embodiments, the cleaning device also includes: a circuit board, the supporting portion includes a first supporting member and a second supporting member, the first supporting member is located on the side of the matching portion away from the sewage tank, and the second supporting member is located on the side of the matching portion facing the sewage tank; when the body is in the lying position, in the height direction, the total thickness of the matching portion and the second supporting member is 90mm-130mm; the circuit board is arranged on one of the first supporting member and the second supporting member.

[0018] Since the fuselage parts corresponding to the power unit and the sewage tank are relatively thick parts of the fuselage, and the thickness of the fuselage part corresponding to the power unit is less than or equal to the thickness of the fuselage part corresponding to the sewage tank, and the matching part is between the power unit and the sewage tank, it plays a role in smoothly connecting the sewage tank and the power unit in appearance, and the sewage tank is installed on the second support member. The actual height of the sewage tank is related to the thickness of the second support member. In this embodiment, the total thickness of the matching part and the second support member is set to 90mm-130mm, which can ensure that the fuselage can fully enter a relatively low and narrow space for cleaning, avoid the existence of cleaning dead zones, and improve the cleaning effect, and can also avoid the situation where the highest point is too low, resulting in a small volume of the sewage tank, affecting the cleaning efficiency.

[0019] In some embodiments, the circuit board is disposed in the first support member, and the circuit board and the power device are arranged side by side.

[0020] In this way, the thickness of the fuselage corresponding to the first support member can be reduced as much as possible.

[0021] In some embodiments, when the fuselage is in the lying-flat position, in the height direction, the sum of the heights of the circuit board and the power device is less than or equal to the height of the highest point.

[0022] In this way, it can be ensured that the fuselage corresponding to the power device and the circuit board is lower than the highest point, thereby ensuring that the fuselage and the floor brush assembly can enter a small space for cleaning operations and ensure the cleaning effect.

[0023] In some embodiments, the circuit board is disposed on the second support member and arranged side by side with the sewage tank.

[0024] This is conducive to further reducing the height of the fuselage corresponding to the first support member, and can avoid the fuselage corresponding to the power device being higher than the highest point, thereby ensuring that the fuselage and the floor brush assembly can enter a small space for cleaning operations and ensure the cleaning effect.

[0025] In some embodiments, the power device includes a suction motor, and when the fuselage is in the upright position, the suction motor has a first suction power; when the fuselage is in the lying position, the suction motor has a second suction power; the ratio of the second suction power to the first suction power is: 0.72-0.78.

[0026] In this way, when the body is in a lying position, it can avoid the situation where the ratio is too large, for example, greater than 0.78, causing the suction motor to absorb water vapor and be damaged, and it can also avoid the situation where the ratio is too small, for example, less than 0.72, causing the suction power of the suction motor to be too small, making it impossible for the cleaning equipment to effectively remove dirt on the surface to be cleaned, resulting in reduced cleaning effect.

[0027] In some embodiments, the power device further includes a battery assembly, and the battery assembly is disposed on a side of the suction motor away from the mating portion.

[0028] Compared with the stacked arrangement of the battery components and the suction motor along the height direction of the fuselage when it is in a lying position, the thickness of the fuselage at the power unit can be further reduced, ensuring that the fuselage can fully enter a relatively low and narrow space for cleaning, avoiding the existence of cleaning dead zones and improving the cleaning effect.

[0029] In some embodiments, the cleaning device further comprises a handle, wherein the handle is disposed at an end of the body away from the floor brush assembly; when the body is in the upright position, a height distance between the handle and the surface to be cleaned is 750 mm-850 mm.

[0030] In this way, when the body is in an upright position, it is convenient for the user to hold the handle.

[0031] In some embodiments, the cleaning device has a static state and a moving state. When the body is in the upright position, the sewage tank has a first static volume in the static state and a first dynamic volume in the moving state. When the body is in the lying position, the sewage tank has a second static volume in the static state and a second dynamic volume in the moving state. The first static volume is greater than the second static volume, and / or the first dynamic volume is greater than the second dynamic volume; and / or the first static volume is greater than the first dynamic volume; and / or the second static volume is greater than the second dynamic volume.

[0032] In some embodiments, the ratio of the first dynamic volume to the first static volume is 0.66-0.68.

[0033] In this way, when the body is in an upright position, it is possible to avoid the ratio of the first dynamic volume to the first static volume being too large, for example, when it is greater than 0.68, part of the water vapor may enter the suction motor due to the surge phenomenon during the movement, thereby ensuring the normal operation of the suction motor. It is also possible to avoid the ratio of the first dynamic volume to the first static volume being too small, for example, when it is less than 0.66, the first dynamic volume is too small, and the cleaning equipment needs to frequently return to the cleaning base station for self-cleaning, which makes the cleaning efficiency of the cleaning equipment low.

[0034] In some embodiments, the ratio of the second dynamic volume to the second static volume is 0.93-0.97.

[0035] In this way, when the fuselage is in a lying position, it is possible to avoid the ratio of the second dynamic volume to the second static volume being too large, for example, when it is greater than 0.97, due to excessive sewage in the moving sewage tank, sewage is easily allowed to enter the suction motor due to a surge phenomenon, thereby ensuring the normal operation of the suction motor. It is also possible to avoid the ratio of the second dynamic volume to the second static volume being too small, for example, when it is less than 0.93, the second dynamic volume is too small, and the cleaning equipment needs to frequently return to the cleaning base station for self-cleaning, resulting in low cleaning efficiency of the cleaning equipment.

[0036] In some embodiments, the ratio of the first dynamic volume to the second dynamic volume is 1.5-1.9.

[0037] The dynamic volume of the sewage tank when the body is in an upright state (i.e., the first dynamic volume) is greater than the dynamic volume when the body is in a lying position (i.e., the second dynamic volume). The volume of the sewage tank can be ensured while ensuring that the sewage is not sucked into the suction motor, thereby ensuring the overall cleaning efficiency of the cleaning equipment.

[0038] The present application also provides a cleaning system, comprising: a cleaning device, which is the cleaning device described in the first aspect above; and a cleaning base station, which is at least configured to clean a floor brush assembly of the cleaning device.

[0039] According to the cleaning system of the present application, by setting the above-mentioned cleaning equipment, it can ensure that the fuselage can completely enter a relatively low and narrow space for cleaning, avoid the existence of cleaning dead zones, and improve the cleaning effect. It can also avoid that when the highest point is too low, the volume of the sewage tank is too small, affecting the cleaning efficiency. In addition, the suction power of the power device can be adjusted according to the state of the fuselage, thereby avoiding the power device from sucking in sewage and being damaged. As a result, the cleaning system can better meet the cleaning needs of users and improve the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] With the development of social economy and the improvement of people's living standards, cleaning equipment such as floor scrubbers have greatly reduced the labor intensity and time spent on housework due to their high mopping efficiency and convenience, and are becoming more and more popular among users. Compared with traditional dry vacuum cleaners, floor scrubbers are larger in size due to the addition of components such as clean water tanks and sewage tanks. When placed flat, the overall height of the body is high. When encountering relatively low and narrow areas to be cleaned, such as the bottom of the sofa, the bottom of the bed, and the legs of the cabinet, the floor brush and the main body cannot be fully extended into the area to be cleaned to complete the cleaning, resulting in a dead zone in the equipment, affecting the cleaning effect.

[0056] In view of this, the embodiments of the present application provide a cleaning device and a cleaning system, which can ensure that the fuselage can enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect. Moreover, when the fuselage is in a flat position, it can prevent the power device from inhaling water vapor, thereby ensuring that the cleaning device works normally in a flat state, so as to better clean the low and narrow space.

[0057] refer to Figure 1-Figure 6 The cleaning device 100 of this embodiment may be a floor scrubber, a vacuum cleaner or other cleaning devices 100. The cleaning device 100 may include: a floor brush assembly 1, a clean water tank, a body 2, a sewage tank 3 and a power device 4.

[0058] The floor brush assembly 1 is used to clean the surface to be cleaned, and the surface to be cleaned can be the ground, the table, the carpet, and other surfaces to be cleaned. For example, the floor brush assembly 1 can be provided with running wheels, and the floor brush assembly 1 can run on the surface to be cleaned through the running wheels. At the same time, the running wheels can also keep the floor brush assembly 1 at a certain height, so that other devices such as a cleaning assembly can be installed at the bottom of the floor brush assembly 1. The cleaning assembly at least includes a roller brush. The roller brush can at least perform wet cleaning on the floor to be cleaned. In one example, the roller brush can also perform dry cleaning on the floor to be cleaned, for example, vacuuming can be performed.

[0059] In some exemplary embodiments, the cleaning assembly may further include a side brush assembly; the side brush assembly is mainly used to move dirt such as dust to the vicinity of the roller brush assembly so as to be processed by the roller brush assembly.

[0060] The clean water tank is arranged on the floor brush assembly 1, and is used for supplying water to the roller brush in the floor brush assembly 1, so that the floor brush assembly 1 can perform wet cleaning on the surface to be cleaned.

[0061] The fuselage 2 is rotatably connected to the floor brush assembly 1 so that the fuselage 2 can rotate between an upright position and a lying position relative to the floor brush assembly 1, wherein when the fuselage 2 is in the lying position, the angle between the fuselage 2 and the surface to be cleaned is 175°-180°. For example, when the fuselage 2 is in the lying position, the angle between the fuselage 2 and the surface to be cleaned can be any point value between 175°-180°. For example, it can be 175°, 176°, 177°, 178°, 179° or 180°. Of course, the present application is not limited thereto. The angle between the fuselage 2 and the surface to be cleaned can be reasonably selected within the above range according to actual needs. It can be understood that within the above angle range, the height of the fuselage 2 from the ground can be made lower, so that the fuselage 2 and the floor brush assembly 1 can be extended into a space with a smaller height, such as the space under the sofa and the space under the bed for cleaning, which can expand the scope of application of the cleaning device 100.

[0062] The sewage tank 3 can be arranged on the body 2, and the sewage tank 3 is connected to the floor brush assembly 1, so that the sewage tank 3 collects the sewage sucked by the floor brush assembly 1. Moreover, compared with the solution of arranging the sewage tank 3 on the body 2, the space occupied by the body 2 can be reduced, which is conducive to the body 2 extending into a small space for cleaning.

[0063] The power device 4 is arranged on the fuselage 2, and the power device 4 can be connected to the sewage tank 3. The power device 4 is at least used to suck the dirt at the floor brush assembly 1 into the sewage tank 3. For example, the power device 4 may at least include a suction motor, and the suction motor is connected to the sewage tank 3. The suction motor is used to output a suction force so that solid dirt and sewage enter the sewage tank 3 through the suction pipeline.

[0064] The power device 4 can be configured so that the suction power when the fuselage 2 is in the lying position is lower than the suction power when the fuselage 2 is in the upright position. Since the height of the power device 4 is lower than that of the sewage tank 3 when the fuselage 2 is in the lying position, for example, the height of the power device 4 is similar to or lower than the height of the sewage tank 3. If the suction power remains unchanged, part of the water vapor may be sucked into the power device 4, causing damage to the power device 4. In this embodiment, the power device 4 is configured so that the suction power when the fuselage 2 is in the lying position is lower than the suction power when the fuselage 2 is in the upright position. The power is appropriately reduced while ensuring the cleaning effect of the surface to be cleaned, so as to avoid the water vapor being sucked into the power device 4, thereby ensuring that the power device 4 can work normally when the fuselage 2 is in the lying position, thereby ensuring the normal operation of the cleaning device 100.

[0065] like Figure 4As shown, when the fuselage 2 is in a lying position, in the height direction, the highest point A of the cleaning device 100 is formed on the matching portion 22 between the sewage tank 3 and the power device 4. Here, the highest point A refers to the position on the fuselage 2 at the largest distance from the ground when the fuselage 2 is in a lying position, that is, the highest point A of the fuselage 2 is on the matching portion 22 between the sewage tank 3 and the power device 4.

[0066] The distance between the highest point A and the surface to be cleaned is 90mm-130mm. For example, the distance between the highest point A and the surface to be cleaned can be any point value between 90mm-130mm. For example, it can be 90mm, 100mm, 110mm, 120mm or 130mm. Of course, this application does not limit this. The distance between the highest point A and the surface to be cleaned can be reasonably selected within the above range according to actual needs. In this way, it can avoid that the highest point A is too high, for example, greater than 130mm, which makes it difficult for the fuselage 2 to fully enter the relatively low and narrow space such as the bottom of the sofa, the bottom of the bed, and around the legs of the cabinet for cleaning, and there is a cleaning dead zone, which affects the cleaning effect. It can also avoid that when the highest point A is too low, for example, less than 90mm, the volume of the sewage tank 3 is too small, and too little sewage and dirt can be collected, which increases the frequency of self-cleaning back to the base station, and reduces the cleaning efficiency.

[0067] According to the cleaning device 100 of the present application, when the body 2 is in a lying position, a highest point A is formed on the matching portion 22 between the sewage tank 3 and the power device 4 of the cleaning device 100, so that the highest point A of the cleaning device 100 in the lying position is away from the floor brush assembly, thereby increasing the length of the cleaning device 100 for entering a low area. In consideration of the volume of the sewage tank 3 on the cleaning device 100 and the height of the low area that can be entered, the present application sets the distance between the highest point A of the cleaning device 100 in the lying position and the surface to be cleaned to 90mm-130mm; wherein, the height of the body 2 of the cleaning device 100 in the lying position does not exceed 130mm, which allows the body 2 to fully enter a relatively low and narrow space for cleaning, avoids the existence of cleaning dead zones, and improves the cleaning effect; at the same time, the height of the body 2 in the lying position is not less than 90mm, which can ensure the volume of the sewage tank 3 when the body 2 enters a relatively low area, thereby improving the cleaning efficiency of the cleaning device 100; to avoid the situation where the volume of the sewage tank 3 is too small due to the thinness of the body 2, thereby affecting the cleaning efficiency. Moreover, since the power device 4 is configured so that the suction power when the fuselage 2 is in the lying position is lower than the suction power when the fuselage 2 is in the upright position, even if the height of the power device 4 relative to the sewage tank 3 is lowered due to the fuselage 2 being in the lying position, it is possible to avoid water vapor being sucked into the power device 4, thereby ensuring that the power device 4 can work normally when the fuselage 2 is in the lying position, so as to better clean low and narrow spaces.

[0068] In some embodiments, reference 1 and Figure 4 The body 2 may include a casing, and the casing may include a supporting portion 21 and a matching portion 22. The supporting portion 21 may extend vertically, and the matching portion 22 may be located at the horizontal side of the supporting portion 21. The supporting portion 21 and the matching portion 22 together enclose an accommodating space 23. At this time, the accommodating space 23 is located at the horizontal side of the supporting portion 21 and the lower side of the matching portion 22, and the sewage tank 3 may be arranged in the accommodating space 23.

[0069] The power device 4 is arranged on the side of the matching part 22 away from the sewage tank 3. For example, the sewage tank 3 can be located at the lower side of the matching part 22, and the power device 4 can be located at the upper side of the matching part 22. When the fuselage 2 is in a lying position, the total thickness of the matching part 22 and the support part 21 in the height direction is 90mm-130mm. For example, when the fuselage 2 is in a lying position, the total thickness of the matching part 22 and the support part 21 in the height direction can be any point value between 90mm-130mm. For example, it can be 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm or 130mm. Of course, the present application is not limited thereto. When the fuselage 2 is in a lying position, the total thickness of the matching part 22 and the support part 21 in the height direction can be reasonably selected within the above range according to actual needs.

[0070] Since the parts of the fuselage 2 corresponding to the power device 4 and the sewage tank 3 are parts of the fuselage 2 with relatively large thickness, the matching part 22 is located between the power device 4 and the sewage tank 3, which not only allows a smooth transition between the sewage tank 3 and the power device 4, but also, when the fuselage 2 is in a flat position, the highest point A of the cleaning device 100 is set on the side surface of the matching part 22 facing away from the support part 21, which can increase the thickness of the sewage tank 3 on the side close to the matching part 22, and further increase the volume of the sewage tank 3. In this embodiment, the total thickness of the matching part 22 and the support part 21 is set to 90mm-130mm, which can ensure that the fuselage 2 can fully enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect, and can also avoid the situation where the highest point A is too low, resulting in a too small volume of the sewage tank 3, affecting the cleaning efficiency.

[0071] In some embodiments, the thickness of the sewage tank 3 when the fuselage 2 is in a flat position has a value range of 107mm-125mm. The thickness of the sewage tank 3 here refers to the distance between the lowest point of the sewage tank 3 in the height direction and the highest point A of the sewage tank 3 in the height direction when the sewage tank 3 and the fuselage 2 are in a flat position. For example, the thickness of the sewage tank 3 when the fuselage 2 is in a flat position can be any point value between 107mm-125mm, for example, it can be 107mm, 110mm, 112mm, 115mm, 118mm, 120mm, 122mm, 124mm or 125mm. Of course, the present application does not limit this. The thickness of the sewage tank 3 when the fuselage 2 is in a flat position can be reasonably selected within the above range according to actual needs. In this way, on the one hand, the thickness of the sewage tank 3 can be guaranteed, and then the volume of the sewage tank 3 can be guaranteed, and the cleaning efficiency can be further improved. It can also avoid the problem that the effective volume of the sewage tank 3 is small due to the small thickness of the sewage tank 3, so that the cleaning device 100 needs to frequently clean the sewage tank 3, and the cleaning efficiency of the cleaning device 100 is low. On the other hand, it can avoid the problem that the thickness of the sewage tank 3 is too large, which leads to the thickness of the fuselage 2 being too large when it is lying flat, and the fuselage 2 cannot enter a relatively low area. And when the total thickness of the fuselage 2 is constant, it can avoid the problem that the thickness of the sewage tank 3 is too large, which leads to the thickness of the support part 21 opposite to the sewage tank 3 being too small, so that the structural strength and stability of the support part 21 are reduced, and the strength of the fuselage 2 is reduced.

[0072] In some embodiments, reference Figure 4 The thickness t1 of the support portion 21 when the fuselage 2 is in the flat position has a value range of 5 mm to 23 mm. The thickness of the support portion 21 here refers to the distance between the lowest point of the support portion 21 in the height direction and the highest point A of the support portion 21 in the height direction when the fuselage 2 is in the flat position. For example, the thickness t1 of the support portion 21 when the fuselage 2 is in the flat position can be any value between 5 mm and 23 mm, such as 5 mm, 8 mm, 10 mm, 12 mm, 15 mm, 18 mm, 20 mm, 22 mm or 23 mm. Of course, the present application does not limit this. The thickness t1 of the support portion 21 when the fuselage 2 is in the flat position can be reasonably selected within the above range according to actual needs.

[0073] In this way, on the one hand, it is possible to avoid the thickness of the support portion 21 being too small, which would reduce the structural strength and stability of the support portion 21 and be unfavorable for better installation of other functional components of the cleaning device 100 such as the sewage tank 3 and the power device 4. On the other hand, it is possible to avoid the thickness of the support portion 21 being too large, which would occupy too much space in the fuselage 2, resulting in a smaller space for accommodating the sewage tank 3, and causing the effective volume of the sewage tank 3 to be smaller, so that the cleaning device 100 needs to frequently return to the cleaning base station for self-cleaning, resulting in low cleaning efficiency of the cleaning device 100.

[0074] In some embodiments, reference Figure 4 When the fuselage 2 is in a lying position, the thickness t2 of the matching portion 22 on the side close to the sewage tank 3 has a value range of 107 mm-125 mm. For example, when the fuselage 2 is in a lying position, the thickness of the matching portion 22 on the side close to the sewage tank 3 can be any point value between 107 mm and 125 mm, for example, it can be 107 mm, 110 mm, 112 mm, 115 mm, 118 mm, 120 mm, 122 mm, 124 mm or 125 mm. Of course, the present application does not limit this. The thickness of the matching portion 22 on the side close to the sewage tank 3 can be reasonably selected within the above range according to actual needs. In this way, the position of the matching portion 22 close to one side of the sewage tank 3 is flush with the outer surface of the sewage tank 3, and the position of the matching portion 22 close to one side of the sewage tank 3 constitutes the highest point A of the fuselage 2 in the lying position, which can ensure that the fuselage 2 can completely enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect, and can also avoid the highest point A being too low, resulting in the sewage tank 3 being too small, affecting the cleaning efficiency.

[0075] In some embodiments, when there is a target obstacle on the surface to be cleaned and there is a cleaning gap in the height direction between the target obstacle and the surface to be cleaned, the height of the cleaning gap is 100mm-170mm, that is, the gap between the top wall and the bottom wall of the cleaning gap is 100mm-170mm. For example, the height of the cleaning gap under the sofa or the bed is any point value between 100mm-170mm, for example, it can be 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm or 170mm. When the floor brush assembly 1 enters the cleaning gap and the body 2 is in a lying position, the distance between the highest point A and the top wall of the cleaning gap is 10mm-80mm. For example, the distance between the highest point A and the top wall of the cleaning gap can be any point value between 10mm-80mm, for example, it can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm or 80mm. Of course, the present application does not limit this. The distance between the highest point A and the top wall of the cleaning gap can vary according to the specific model of the cleaning equipment 100 and the size structure of the target obstacle.

[0076] In this way, on the one hand, collision or interference between the highest point A of the fuselage 2 and the top wall of the cleaning gap is avoided, so that the fuselage 2 can completely enter the low and narrow cleaning gap for cleaning, avoiding the existence of cleaning dead zones, improving the cleaning effect, and improving the user experience. On the other hand, while ensuring that the fuselage 2 can enter the cleaning gap and has a certain distance from the top wall of the cleaning gap, the thickness of the sewage tank 3 can be increased as much as possible, thereby increasing the effective volume of the sewage tank 3, which helps to reduce the frequency of the cleaning equipment 100 returning to the cleaning base station for self-cleaning, thereby improving the cleaning efficiency.

[0077] In some embodiments, reference Figure 4 The cleaning device 100 may further include a circuit board 5. Specifically, the support portion 21 includes a first support member and a second support member, the first support member is located on a side of the matching portion 22 away from the sewage tank 3, and the second support member is located on a side of the matching portion 22 facing the sewage tank 3, that is, the first support member and the power device 4 are located on the same side of the matching portion 22, and the second support member and the sewage tank 3 are located on the same side of the matching portion 22.

[0078] When the fuselage 2 is in a lying flat position, the total thickness of the matching part 22 and the second support member in the height direction is 90mm-130mm. For example, when the fuselage 2 is in a lying flat position, the total thickness of the matching part 22 and the second support member in the height direction can be any point value between 90mm-130mm, for example, it can be 90mm, 95mm, 100mm, 105mm, 110mm, 115mm, 120mm, 125mm or 130mm. Of course, the present application is not limited to this. When the fuselage 2 is in a lying flat position, the total thickness of the matching part 22 and the second support member in the height direction can be reasonably selected within the above range according to actual needs.

[0079] Since the parts of the fuselage 2 corresponding to the power device 4 and the sewage tank 3 are parts of the fuselage 2 with relatively large thickness, and the thickness of the part of the fuselage 2 corresponding to the power device 4 is less than the thickness of the part of the fuselage 2 corresponding to the sewage tank 3, and the matching portion 22 is located between the power device 4 and the sewage tank 3, and plays a role in smoothly connecting the sewage tank 3 and the power device 4 in appearance, the sewage tank 3 is installed on the second support member, and the actual height of the sewage tank 3 is related to the thickness of the second support member. In this embodiment, the total thickness of the matching portion 22 and the second support member is set to 90mm-130mm, which can ensure that the fuselage 2 can fully enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect, and can also avoid the highest point A being too low, resulting in the sewage tank 3 being too small in size, affecting the cleaning efficiency.

[0080] The circuit board 5 is disposed on one of the first support member and the second support member, that is, the circuit board 5 is disposed on the first support member, or the circuit board 5 is disposed on the second support member. When the circuit board 5 is disposed on the first support member, it helps to reduce the thickness of the body 2 at the second support member, and when the circuit board 5 is disposed on the second support member, it helps to reduce the thickness of the body 2 at the first support member. In this way, the arrangement of the circuit board 5 is diverse, which can meet the different thickness requirements of the cleaning device 100.

[0081] Optionally, the first support member and the second support member may be an integrated structure, or may be a split structure and are connected by mechanical connection.

[0082] In some embodiments, the circuit board 5 is disposed in the first support member, and the circuit board 5 and the power device 4 are arranged side by side. For example, when the fuselage 2 is in a lying position, the thickness direction of the circuit board 5 can be parallel to the thickness direction of the power device 4. At this time, the circuit board 5 is located on the upper side or lower side of the power device 4 in the lying state; or, when the fuselage 2 is in a lying position, the thickness direction of the circuit board 5 can be perpendicular to the thickness direction of the power device 4. At this time, the circuit board 5 is located on the horizontal side (for example, the left side or the right side) of the power device 4 in the lying state. In this way, the thickness of the fuselage 2 corresponding to the first support member can be reduced as much as possible.

[0083] In some embodiments, when the fuselage 2 is in a lying position, in the height direction, the sum of the heights of the circuit board 5 and the power device 4 is less than or equal to the height of the highest point A. In this way, it can be ensured that the fuselage 2 corresponding to the power device 4 and the circuit board 5 is lower than the highest point A, thereby ensuring that the fuselage 2 and the floor brush assembly 1 can enter a small space for cleaning operations, thereby ensuring the cleaning effect.

[0084] In some embodiments, reference Figure 4 The circuit board 5 is arranged on the second support member and arranged side by side with the sewage tank 3. This is conducive to further reducing the height of the fuselage 2 corresponding to the first support member, and can avoid the fuselage 2 corresponding to the power device 4 being higher than the highest point A, thereby ensuring that the fuselage 2 and the floor brush assembly 1 can enter a small space for cleaning operations and ensure the cleaning effect.

[0085] In some embodiments, the power device 4 may include a suction motor, and when the fuselage 2 is in an upright position, the suction motor has a first suction power; when the fuselage 2 is in a lying position, the suction motor has a second suction power; the ratio of the second suction power to the first suction power is: 0.72-0.78. In one example, it can be any point value between 0.72-0.78, for example, the ratio of the second suction power to the first suction power can be 0.72, 0.73, 0.74, 0.75, 0.76, 0.77 or 0.78, of course, the present application does not limit this, and the ratio of the second suction power to the first suction power can be reasonably selected within the above range according to actual needs. In this way, when the body 2 is in a lying position, it can avoid the situation where the ratio is too large, for example, greater than 0.78, causing the suction motor to absorb water vapor and be damaged, and it can also avoid the situation where the ratio is too small, for example, less than 0.72, causing the suction power of the suction motor to be too small, making the cleaning device 100 unable to effectively remove dirt on the surface to be cleaned, resulting in reduced cleaning effect.

[0086] Table 1 Water vapor content detection table of the suction motor at different second suction powers

[0087]

[0088] The inventor of the present application has tested the water vapor in the air sucked in when the suction motor is running at different second suction powers. By analyzing the test data in the above table, it can be seen that when the fuselage 2 is in a lying position, the suction power of the suction motor can avoid a large amount of water vapor being sucked into the exhaust fan when it is reduced by 22%. After testing and comparison, when the power of the suction motor is reduced to 75%±3% of the normal use power (i.e., reduced by 25%), the effect of avoiding the suction of sewage into the suction motor can be basically achieved, while ensuring that the suction force of the suction motor meets the cleaning needs.

[0089] In summary, when the body 2 is in a lying position, the suction power of the suction motor is actively reduced to reduce the suction force of the suction motor on the sewage in the sewage tank 3, so that when the cleaning equipment 100 cleans the low area, it can continue to clean without turning off the negative pressure source, while preventing water vapor from entering the suction motor.

[0090] In some embodiments, the cleaning device 100 may include a control device, which may be configured to control the operating power of the suction motor to decrease from the first suction power to the second suction power when a power adjustment instruction is obtained, wherein obtaining the power adjustment instruction may include: actively detecting whether the body 2 has reached the lying position through an angle sensor; or, the power adjustment instruction may be triggered through external instruction input, other environmental condition detection, physical buttons, etc. In this way, the power adjustment of the suction motor is realized in a variety of ways, which can better meet the power adjustment requirements and improve the user experience.

[0091] In some embodiments, the power device 4 may also include a battery assembly, for example, the battery assembly may be a battery pack, and the battery assembly is arranged on the side of the suction motor away from the mating portion 22, that is, the battery assembly and the suction motor are arranged along the length direction of the fuselage 2 when it is in a flat position, which can further reduce the thickness of the fuselage 2 at the power device 4 compared to the stacked arrangement of the battery assembly and the suction motor along the height direction of the fuselage 2 when it is in a flat position, and ensure that the fuselage 2 can fully enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect. Optionally, the size and shape of the battery assembly can also be flexibly adjusted as needed to reduce the thickness of the fuselage 2 at the power device 4.

[0092] In some embodiments, the cleaning device 100 may further include a handle 6, which is disposed at one end of the body 2 away from the floor brush assembly 1, and the handle 6 can be convenient for the user to hold to push the cleaning device 100 to move and adjust the moving direction. When the body 2 is in an upright position, the distance between the handle 6 and the surface to be cleaned in the height direction is 750mm-850mm. In one example, the distance between the handle 6 and the surface to be cleaned in the height direction can be any point value between 750mm-850mm. For example, when the body 2 is in an upright position, the distance between the handle 6 and the surface to be cleaned in the height direction can be 750mm, 760mm, 770mm, 780mm, 790mm, 800mm, 810mm, 820mm, 830mm, 840mm or 850mm, so that when the body 2 is in an upright position, it is convenient for the user to hold the handle 6.

[0093] In some embodiments, the cleaning device 100 may have a static state and a moving state, wherein when the fuselage 2 is in an upright position, the sewage tank 3 has a first static volume in a static state and a first dynamic volume in a moving state, and when the fuselage 2 is in a lying position, the sewage tank 3 has a second static volume in a static state and a second dynamic volume in a moving state. It should be noted that the static state here means that the cleaning device 100 is turned on and running, but the cleaning device 100 remains static and does not move, while draining water and absorbing water, until the sewage tank 3 stops for protection; dynamic means: the cleaning device 100 is turned on and running, the moving speed is 0.5-0.6m / s, while draining water and absorbing water, until the sewage tank 3 stops for protection. Preferably, the moving speed can be 0.55m / s.

[0094] Among them, the first static volume is greater than the second static volume. It can be understood that since the depth of the sewage tank 3 in the height direction is smaller when the fuselage 2 is in a lying position than when the fuselage 2 is in an upright position, it is more likely to cause sewage to enter the suction motor due to surge. Therefore, the first static volume can be greater than the second static volume.

[0095] The first dynamic volume is greater than the second dynamic volume. It can be understood that since the depth of the sewage tank 3 in the height direction is smaller when the fuselage 2 is in a lying position than when the fuselage 2 is in an upright position, it is more likely to cause sewage to enter the suction motor due to surge. Therefore, the first dynamic volume can be greater than the second dynamic volume.

[0096] The first static volume is greater than the first dynamic volume. It can be understood that when the cleaning device 100 is in dynamic state, the sewage in the sewage tank 3 is prone to surge, causing the sewage to enter the suction motor. Therefore, the first static volume is greater than the first dynamic volume, which can prevent sewage from entering the suction motor.

[0097] The second static volume is greater than the second dynamic volume. It can be understood that when the cleaning device 100 is in dynamic state, the sewage in the sewage tank 3 is prone to surge, causing the sewage to enter the suction motor. Therefore, the second static volume is greater than the second dynamic volume, which can prevent sewage from entering the suction motor.

[0098] In some embodiments, the ratio of the first dynamic volume to the first static volume is 0.66-0.68. In one example, the ratio of the first dynamic volume to the first static volume can be any point value between 0.66-0.68. For example, the ratio of the first dynamic volume to the first static volume can be 0.66, 0.67 or 0.68. Of course, the present application does not limit this. The ratio of the first dynamic volume to the first static volume can be reasonably selected within the above range as needed. In this way, when the fuselage 2 is in an upright position, it can be avoided that the ratio of the first dynamic volume to the first static volume is too large, for example, when it is greater than 0.68, part of the water vapor may enter the suction motor due to the surge phenomenon during the movement, thereby ensuring the normal operation of the suction motor, and it can also be avoided that the ratio of the first dynamic volume to the first static volume is too small, for example, when it is less than 0.66, the first dynamic volume is too small, and the cleaning device 100 needs to frequently return to the cleaning base station for self-cleaning, so that the cleaning efficiency of the cleaning device 100 is low.

[0099] In some embodiments, the ratio of the second dynamic volume to the second static volume is 0.93-0.97. In one example, the ratio of the second dynamic volume to the second static volume can be any point value between 0.93-0.97. For example, the ratio of the second dynamic volume to the second static volume can be 0.93, 0.67 or 0.68, and of course the present application is not limited thereto, and the ratio of the second dynamic volume to the second static volume can be reasonably selected within the above range as needed. In this way, when the body 2 is in a lying position, it is possible to avoid the ratio of the second dynamic volume to the second static volume being too large, for example, when it is greater than 0.97, due to the excessive amount of sewage in the moving sewage tank 3, the sewage is easy to enter the suction motor due to the surge phenomenon, thereby ensuring the normal operation of the suction motor. It is also possible to avoid the ratio of the second dynamic volume to the second static volume being too small, for example, when it is less than 0.93, the second dynamic volume is too small, and the cleaning device 100 needs to frequently return to the cleaning base station for self-cleaning, which makes the cleaning efficiency of the cleaning device 100 low.

[0100] In some embodiments, the ratio of the first dynamic volume to the second dynamic volume is 1.5-1.9. For example, the ratio of the first dynamic volume to the second dynamic volume can be 1.5, 1.6, 1.7, 1.8 or 1.9. Of course, the present application does not limit this. The ratio of the first dynamic volume to the second dynamic volume can be reasonably selected within the above range as needed. It can be understood that since the depth of the sewage tank 3 in the height direction is smaller when the fuselage 2 is in the lying position than when the fuselage 2 is in the upright position, it is more likely to cause the sewage to enter the suction motor due to surge. Therefore, in this embodiment, the dynamic volume of the sewage tank 3 when the fuselage 2 is in the upright state (i.e., the first dynamic volume) is greater than the dynamic volume when the fuselage 2 is in the lying position (i.e., the second dynamic volume). The volume of the sewage tank 3 can be ensured on the premise of ensuring that the sewage is not sucked into the suction motor, thereby ensuring the overall cleaning efficiency of the cleaning device 100.

[0101] Table 2 Effective volume of sewage tank in different states

[0102]

[0103] The above table shows a specific embodiment of the effective volume of the sewage tank 3 of the present application in different states. It can be seen from the above table that the sewage tank 3 of the embodiment of the present application is configured to have corresponding volumes in static, dynamic, when the fuselage 2 is in an upright position, and when the fuselage 2 is in a flat position. As a result, the cleaning device 100 can fully clean a small space in the flat position, and has an appropriate effective volume in the flat position to ensure that the suction motor will not suck the sewage in the sewage tank 3 when cleaning in the flat state, thereby ensuring the reliability and safety of the cleaning process.

[0104] In some possible embodiments, the suction motor can be arranged at a position of the body 2 connected to the handle 6, so that when the body 2 is in a lying position, the length of the body 2 that can be extended into a narrow space is increased as much as possible, thereby expanding the cleaning range, improving the cleaning quality, and improving the user experience.

[0105] In some possible embodiments, the sewage tank 3 may be cylindrical, so that the structure of the sewage tank 3 is relatively simple. Optionally, in order to further reduce the thickness of the sewage tank 3 while ensuring the volume of the sewage tank 3, the sewage tank 3 may also be set to a flat structure, for example, the cross section of the sewage tank 3 is roughly in an oblong, elliptical, square, etc. shape, that is, by increasing the size of the sewage tank 3 extending along the fuselage 2 to reduce the thickness of the sewage tank 3, so as to ensure that the fuselage 2 can be extended into a small space to complete cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect.

[0106] The cleaning system of the second embodiment of the present application is described below.

[0107] The cleaning system of this embodiment may include: the cleaning device 100 and the cleaning base station in the above embodiment. The cleaning base station is at least configured to clean the floor brush assembly 1 of the cleaning device 100. For example, after the floor brush assembly 1 completes the cleaning task, it can be moved to the cleaning base station, and the cleaning base station cleans the roller brush assembly, mop assembly, side brush assembly, etc. of the floor brush assembly 1. In addition, the cleaning base station can also be used to discharge sewage in the sewage tank 3.

[0108] According to the cleaning system of the embodiment of the present application, by setting the cleaning device 100 in the above embodiment, it can ensure that the fuselage 2 can completely enter a relatively low and narrow space for cleaning, avoid the existence of a cleaning dead zone, and improve the cleaning effect. It can also avoid that when the highest point A is too low, the volume of the sewage tank 3 is too small, affecting the cleaning efficiency. In addition, the suction power of the power device 4 can be adjusted according to the state of the fuselage 2, so as to avoid the power device 4 from sucking in sewage and being damaged. Therefore, the cleaning system can better meet the cleaning needs of users and improve the user experience.
