Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a floating cleaning component, cleaning equipment, and cleaning method. Background Technology

[0002] Please see Figure 1 As shown, the cleaning device 100 includes a body 110, main wheels 120 connected to the body 110, and a cleaning assembly 200 for cleaning surfaces to be cleaned. The cleaning assembly 200 typically includes a roller brush 210 and a scraper 220 disposed behind the roller brush 210. The roller brush 210 is rotatably connected to the body 110, while the scraper 220 is fixedly connected to the body 110. The scraper 220 has a first interference fit with the surface to be cleaned to maintain contact with it; the roller brush 210 has a second interference fit with the surface to be cleaned to maintain contact between the bristles of the roller brush 210 and the surface to be cleaned.

[0003] Please see here. Figure 2 As shown, if the diameter of the roller brush 210 increases (e.g., a newly replaced roller brush 210), the position of the machine body 110 will be higher, and the first interference fit between the scraper 220 and the surface to be cleaned will be smaller. The scraper 220 may not be able to effectively clean the surface or may even fail to contact it. Please refer to... Figure 3 As shown, if the diameter of the roller brush 210 becomes smaller (for example, due to wear, the bristles of the roller brush 210 continuously decrease or collapse), the position of the machine body 110 will be lower, and the first interference between the scraper 220 and the surface to be cleaned will be larger. The running resistance of the scraper 220 will increase and affect the cleaning effect.

[0004] This makes it difficult for the interference between the scraper 220 and the surface to be cleaned to match the design value during actual use. In particular, as the cleaning device is used, the bristles of the roller brush 210 will inevitably become shorter and collapse, which will cause the diameter of the roller brush 210 to decrease continuously and increase the interference between the scraper 220 and the surface to be cleaned, thus affecting the cleaning effect. Summary of the Invention

[0005] This application provides a floating cleaning component, cleaning equipment, and cleaning method to solve the problem that the height of a fixed scraper cannot be adjusted, resulting in the inability to adjust the interference fit between the scraper and the surface to be cleaned.

[0016] In some embodiments, one of the base and the floating member is provided with a guide portion arranged along the first direction; the other is provided with a mating portion that can mate with the guide portion.

[0017] In some embodiments, the pushing member is an elastic member, and the first connecting portion and the second connecting portion are the two ends of the elastic member; the guide hole has a step on the side near the elastic member to cooperate in connecting the first connecting portion.

[0045] This application provides a floating cleaning component, cleaning equipment, and cleaning method, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0046] Please see Figure 4 and Figure 5 As shown, an embodiment of this application provides a floating cleaning component 900 for cleaning a surface 300 to be cleaned, which includes a base 910, a scraper 920, a support wheel 930, and a floating device 940.

[0047] The base 910 serves as a carrier for supporting and connecting other components. In some embodiments, please refer to... Figure 4 As shown, the base 910 is part of the base 910 of a cleaning device 800, and the scraper 920, the support wheel 930, and the floating device 940 are connected to the base of the cleaning device 800. In other embodiments, the base 910 may be a structure separate from the base of the cleaning device 800, and the base 910 may be mounted on the base of the cleaning device 800 to achieve the connection between the floating cleaning assembly 900 and the base of the cleaning device 800.

[0048] The scraper 920 is disposed on the floating device 940. When the floating cleaning assembly 900 is working, the scraper 920 contacts the surface 300 to be cleaned for cleaning.

[0049] Specifically, the scraper 920 has a first interference fit with the surface 300 to be cleaned, for cleaning the surface 300.

[0050] The support wheel 930 is mounted on the floating device 940, and the floating cleaning component 900 is supported by the support wheel 930 on the surface to be cleaned 300, and the support wheel 930 can move on the surface to be cleaned 300.

[0051] The floating device 940 is floatingly connected to the base 910 and can drive the scraper 920 and the support wheel 930 to float relative to the base 910 in a first direction, so that the scraper 920 and the support wheel 930 can maintain a close contact with the surface 300 to be cleaned.

[0052] Wherein, the first direction is a direction perpendicular to the surface 300 to be cleaned. For example, please refer to [reference needed]. Figure 4 and Figure 5 , Figure 4 and Figure 5 The direction indicated by the middle arrow is the first direction.

[0053] The "adhering state" means that the support wheel 930 is supported on the surface 300 to be cleaned and can move on the surface 300 to be cleaned; and the scraper 920 is in close contact with the surface 300 to be cleaned. For example, the first interference fit is maintained within a preset range.

[0054] Here, the floating device 940 allows the scraper 920 and the support wheel 930 to be floatingly connected to the base 910. This is because, when the scraper 920 is floated alone, its floating position is difficult to determine, especially when the scraper 920 is made of a flexible material such as rubber. The free end 921 of the scraper 920 in contact with the surface to be cleaned 300 can undergo significant deformation, thus affecting the first interference fit. To better maintain the floating position of the scraper 920, a stop member is also needed to limit its position. However, when the floating cleaning assembly 900 is working, relative friction will occur between the stop member and the surface to be cleaned 300, which will not only affect the cleaning effect and increase the operating resistance of the floating cleaning assembly 900, but may also cause scratches to the surface to be cleaned 300.

[0055] In the floating cleaning assembly 900 of this application, when the distance between the base 910 and the surface 300 to be cleaned changes, since the floating device 940 is floatingly connected to the base 910, the scraper 920 and the support wheel 930 disposed on the floating device 940 can float accordingly. That is, the positions of the scraper 920 and the support wheel 930 are relatively fixed and can float together along the first direction. In other words, the floating device 940 can adjust the position of the scraper 920 by adjusting the position of the support wheel 930 relative to the base 910.

[0056] It is understood that in the floating cleaning component 900 of this application, the first interference fit between the scraper 920 and the surface to be cleaned 300 is maintained within a preset range, which helps to ensure cleaning efficiency, reduce wear between the scraper 920 and the surface to be cleaned 300, and improve service life.

[0057] Furthermore, in the floating cleaning component 900 of this application, the position to which the scraper 920 needs to be adjusted is determined by adjusting the position of the support wheel 930 supporting the base 910. The structure is simple and does not require additional stop members to restrict the position of the scraper 920. Moreover, the support wheel 930 and the surface to be cleaned 300 have rolling friction, which is small and will not affect the cleaning effect and user experience of the floating cleaning component 900.

[0058] In some embodiments, the floating device 940 includes a floating member 941 and a pushing member 942, wherein the scraper 920 and the support wheel 930 are disposed on the floating member 941; the pushing member 942 floats the floating member 941 to the base 910 and is capable of providing a force to the floating member 941 toward the surface to be cleaned 300, thereby enabling the floating member 941 to float along the first direction.

[0059] It can be seen that when the distance between the base 910 and the surface to be cleaned 300 changes, the pushing member 942 can adaptively adjust the distance between the floating member 941 and the base 910, so that the scraper 920 and the support wheel 930 connected to the floating member 941 maintain contact with the surface to be cleaned 300.

[0060] The pushing member 942 includes a first connecting part 9421 and a second connecting part 9422. The first connecting part 9421 is connected to the floating member 941, and the second connecting part 9422 is connected to the base 910.

[0061] In some examples, please refer to Figure 5 As shown, the pushing member 942 is an elastic member, such as a spring, a sheet, or an elastic connector made of elastic material. The first connecting part 9421 and the second connecting part 9422 are the two ends of the elastic member. When the distance between the base 910 and the surface to be cleaned 300 changes, the elastic member can generate elastic deformation in the first direction so that the floating member 941 can drive the scraper 920 and the support wheel 930 to move, and automatically adjust the distance between the scraper 920 and the support wheel 930 and the surface to be cleaned 300. That is, the distance between the scraper 920 and the support wheel 930 and the base 910 can change adaptively, and maintain the contact state between the scraper 920 and the support wheel 930 and the surface to be cleaned 300.

[0062] In some examples, the pushing member 942 includes two mutually repulsive magnets, which serve as the first connecting part 9421 and the second connecting part 9422, respectively. One magnet is fixedly connected to the floating member 941, and the other magnet is fixedly connected to the base 910. When the distance between the base 910 and the surface to be cleaned 300 changes, the distance between the two mutually repulsive magnets can change accordingly to maintain the contact state between the scraper 920 and the support wheel 930 and the surface to be cleaned 300.

[0063] In some examples, the pressing member 942 is a damping bearing, with one of the first connecting portion 9421 and the second connecting portion 9422 serving as the stator and the other as the rotor. In use, the floating member 941 is rotatable so that the support wheel 930 contacts the surface to be cleaned 300, at which point the scraper 920 has the first interference fit with the surface to be cleaned 300. When the distance between the base 910 and the surface to be cleaned 300 changes, the floating member 941 rotates around the damping bearing, causing the distance between the support wheel 930 and the base 910 to change accordingly, maintaining contact between the support wheel 930 and the surface to be cleaned 300, and maintaining the first interference fit. For example, when the distance between the base 910 and the surface to be cleaned 300 decreases, the floating member 941 rotates toward the base 910 to maintain the contact state between the scraper 920 and the support wheel 930 and the surface to be cleaned 300.

[0064] In some embodiments, based on the floating member 941 and the pushing member 942, one of the base 910 and the floating member 941 is provided with a guide portion 943, which is disposed along the first direction; the other is provided with a mating portion 944, which engages with the guide portion 943. It is understood that the engagement of the guide portion 943 and the mating portion 944 restricts the relative positional change between the base 910 and the floating member 941 to the first direction, thereby making the floating direction of the floating member 941 more accurate.

[0065] In some examples, the guide portion 943 is a guide protrusion disposed on the base 910; the mating portion 944 is a guide hole disposed on the floating member 941. It is understood that in other examples, the guide protrusion may also be disposed on the floating member 941, and correspondingly, the guide hole may be disposed on the base 910.

[0066] In a further example, the pushing member 942 is an elastic member, and the first connecting part 9421 and the second connecting part 9422 are the two ends of the elastic member; the guide hole is provided with a step 9441 on the side near the elastic member, that is, the guide hole is a stepped hole 9441, and the first connecting part 9421 is fitted and connected to the step 9441 in order to realize the positioning of the first connecting part 9421.

[0067] For example, please refer to Figure 5As shown, the guide portion 943 is a vertically arranged cylindrical guide protrusion disposed on the base 910; the mating portion 944 is a cylindrical stepped guide hole 9441 disposed on the floating member 941, and the guide hole is mated to the circumferential outer side of the guide protrusion so that the floating member 941 can move along the setting direction of the guide protrusion. The elastic member is a spring, the upper end of which is connected to the base 910, and the lower end of which is connected to the step 9441 of the guide hole.

[0068] The cleaning device 800 typically includes a suction assembly 830 and a dust collection assembly. The suction assembly 830 is used to suck dust and other contaminants into the dust collection assembly during cleaning. The scraper 920 is usually positioned near the suction assembly 830. To avoid potential suction loss in the suction assembly 830 when the scraper 920 floats, in some embodiments, one end of the scraper 920 is a fixed end 922 connected to the base 910; the other end of the scraper 920 is a free end 921, which is in contact with the surface 300 to be cleaned. For example, the free end 921 and the surface 300 to be cleaned have a first interference fit within a preset range to ensure cleaning effectiveness.

[0069] It is understood that one end of the scraper 920 is connected to the base 910, and the other end maintains the first interference fit with the surface to be cleaned 300, that is, forming a sealing part that blocks the airflow and prevents the suction of the vacuuming assembly 830 from leaking due to the gap between the scraper 920 and the base 910.

[0070] In some examples, the scraper 920 has a bent section 923 located between the free end 921 and the fixed end 922. The bent section 923 reduces the stress generated between the free end 921 and the fixed end 922 when the scraper 920 floats, thus extending the service life of the scraper 920.

[0071] For example, please refer to Figure 5As shown, the scraper 920 includes a first segment 924, a bent segment 923, and a second segment 925 arranged sequentially. The second segment 925 is connected to the floating device 940. The fixed end 922 is the end of the first segment 924, and the free end 921 is the end of the second segment 925. A mating groove 911 is provided in the base 910 corresponding to the first segment 924, and the first segment 924 is embedded in the mating groove 911 of the base 910. The bent segment 923 is located between the first segment 924 and the second segment 925, and the bent segment 923 extends generally in a direction away from the surface to be cleaned 300. It is understood that in other embodiments, the bending direction of the bent segment 923 may be different.

[0072] Application Example 1

[0073] In application example 1, the floating cleaning component 900 is applied in a floor cleaning device. The squeegee and the support wheel 930 are floatingly connected to the base 910 via the floating device 940. The base 910 is the body of the floor cleaning device 800. The floating cleaning component 900 also includes a roller brush 820, which is connected to the base 910 and located in front of the squeegee. The roller brush 820 has a second interference fit with the surface 300 to be cleaned.

[0074] The "front side" refers to the front side of the floating cleaning component 900 in its operating direction. When using the floor cleaning device 800, the roller brush 820 located on the front side first cleans the floor, and the scraper located on the rear side scrapes the floor again to remove the cleaning liquid left on the floor by the roller brush 820.

[0075] For initial use, please refer to Figure 6 As shown, the bristles on the roller brush 820 are relatively long, and the distance between the base 910 and the ground is relatively large. Here, due to the floating device 940, the scraper and the support wheel 930 can float vertically downward relative to the base 910, so that the scraper and the support wheel 930 can maintain contact with the ground. Specifically, the first interference fit between the free end 921 of the scraper and the ground is also kept within a preset range.

[0076] With the use of the aforementioned floor cleaning equipment, please refer to Figure 4As shown, the bristles on the roller brush 820 gradually collapse, reducing the distance between the base 910 and the ground. Here, due to the floating device 940, the scraper and the support wheel 930 can float vertically relative to the base 910, ensuring that the scraper and the support wheel 930 remain in contact with the ground. Specifically, the first interference fit between the free end 921 of the scraper and the ground is also kept within a preset range.

[0077] Application Example 2

[0078] In application example two, the floating cleaning component 900 is also applied to a floor cleaning device. The difference is that the floor cleaning device further includes a vacuuming component 830, which covers part of the outer periphery of the roller brush 820 to absorb dust and other contaminants. One end of the scraper is a fixed end 922, which is connected to the base 910; the other end of the scraper 920 is a free end 921, which has the first interference fit with the ground.

[0079] In use, the roller brush 820 is driven to rotate by a drive mechanism such as a motor, while the dust collection assembly 830 creates negative pressure on a portion of the outer periphery of the roller brush 820 to suck up dust and other contaminants. The scraper is spaced between the base 910 on the rear side of the roller brush 820 and the ground to reduce suction loss of the dust collection assembly 830.

[0080] As previously stated, the floating cleaning component 900 can be applied in the cleaning device 800, which can perform cleaning during operation via the floating cleaning component 900. Accordingly, this application also provides a cleaning device 800 for cleaning a surface 300 to be cleaned, which includes a base 910, a roller brush 820, wheels 810, and the floating cleaning component 900.

[0081] The base 910 is the main structure of the cleaning device 800, used to support and connect other components; the walking wheel 810 is disposed on the base 910 and used to walk on the surface 300 to be cleaned; the roller brush 820 is disposed on the base 910 and is disposed opposite to the walking wheel 810, and the roller brush 820 is used to clean the surface 300 to be cleaned.

[0082] The floating cleaning assembly 900 includes a base 910, a scraper 920, a support wheel 930, and a floating device 940. The scraper 920 is a scraper blade disposed on the floating device 940 and is typically located behind the roller brush 820. The support wheel 930 is disposed on the floating device 940 and can travel on the surface 300 to be cleaned. The floating device 940 is floatingly connected to the base 910 and can drive the scraper 920 and the support wheel 930 to float relative to the base 910 in a first direction, so that the scraper 920 and the support wheel 930 can maintain a close contact with the surface 300 to be cleaned.

[0083] Here, the support wheel 930, the roller brush 820, and the traveling wheel 810 jointly support the base 910. Exemplarily, the roller brush 820 is driven by a power device for cleaning; the diameter of the support wheel 930 is smaller than the diameter of the traveling wheel 810, and the support wheel 930 and the traveling wheel 810 are moved manually or mechanically to achieve the movement of the cleaning device 800.

[0084] In some embodiments, the floating device 940 includes a floating member 941 and a pushing member 942, wherein the scraper 920 and the support wheel 930 are connected to the floating member 941; the pushing member 942 includes a first connecting portion 9421 and a second connecting portion 9422, the first connecting portion 9421 being connected to the floating member 941 and the second connecting portion 9422 being connected to the base 910, and the pushing member 942 being able to provide a force to the floating member 941 toward the surface to be cleaned 300 and enable the floating member 941 to float along the first direction.
