Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, specifically to a roller brush, cleaning equipment, and cleaning system. Background Technology

[0002] Cleaning equipment refers to common intelligent cleaning appliances, such as robotic vacuum cleaners and automatic sweeping machines. These devices can perform deep cleaning, including vacuuming, on floors, tiles, and carpets.

[0003] The roller brush is one of the key components of cleaning equipment. By rotating, the roller brush agitates and sweeps up dust, hair, debris, and other particles from crevices in the floor, which are then sucked into the dustbin by suction. A roller brush consists of rubber strips and bristles. The bristles are used to clean hard surfaces such as hard floors and tiles, while the rubber strips are better suited for cleaning soft surfaces such as carpets.

[0004] In related technologies, along the radial direction of the roller brush, the height of the bristles is higher than the height of the rubber strip. When cleaning soft floors such as carpets, the rubber strip cannot make full contact with the carpet, resulting in poor cleaning ability for soft floors such as carpets. Utility Model Content

[0005] This disclosure provides a roller brush, cleaning equipment, and cleaning system. By adjusting the radial height of the bristles and scraper along the roller brush, the cleaning ability of the roller brush on the ground in different ground environments can be improved.

[0006] On one hand, this disclosure provides a roller brush, which includes:

[0007] Support cylinder;

[0008] A first cleaning part is disposed in the support cylinder, and at least a portion of the first cleaning part protrudes from the outer wall of the support cylinder along the radial direction of the support cylinder.

[0009] The second cleaning part is movably connected to the support cylinder along the radial direction of the support cylinder, and the second cleaning part has a first position and a second position.

[0010] A drive assembly is connected to a second cleaning part and is used to drive the second cleaning part to move between a first position and a second position.

[0011] Along the radial direction of the support cylinder, the dimensions of the second cleaning part in the first position and the dimensions of the second cleaning part in the second position have a height difference.

[0012] The roller brush disclosed herein allows for radial height adjustment of the second cleaning section's height within the support cylinder by setting a radial height difference between the dimensions of the second cleaning section in the first position and its dimensions in the second position. Therefore, when cleaning a surface to be cleaned using the second cleaning section, the contact depth between the second cleaning section and the surface to be cleaned is adjustable. By adjusting the second cleaning section at different positions, the interference fit between the second cleaning section and the surface to be cleaned can be adjusted, thereby improving the cleaning effect. Furthermore, when cleaning uneven surfaces, the contact depth between the second cleaning section and the surface to be cleaned can maintain an optimal cleaning depth, further enhancing the cleaning effect of the second cleaning section.

[0013] Specifically, when cleaning a recessed surface, the height of the second cleaning part along the radial direction of the support cylinder can be increased to ensure sufficient contact between the second cleaning part and the surface to be cleaned, thereby improving the cleaning effect on the recessed surface. When cleaning a raised surface, the height of the second cleaning part along the radial direction of the support cylinder can be decreased to prevent excessive contact between the second cleaning part and the surface to be cleaned. This helps reduce the possibility of excessive interference between the second cleaning part and the surface to be cleaned, which could easily damage the second cleaning part.

[0014] Furthermore, when cleaning surfaces of different materials, the radial height of the second cleaning section in the support cylinder can be adjusted so that the cleaning structure on the roller brush that contacts the surface to be cleaned is the first cleaning section and / or the second cleaning section. This ensures that when the roller brush cleans surfaces of different materials, there is sufficient contact between the different cleaning structures and the surface to be cleaned, thereby improving the cleaning effect on surfaces of different materials.

[0015] The first cleaning part may protrude from the outer wall of the support cylinder. Since the second cleaning part has a first position and a second position along the radial direction of the support cylinder, and the first position and the second position have a height difference, a height difference can exist between the second cleaning part and the first cleaning part. This height difference can be greater than or equal to 0.

[0016] Specifically, when the radial height difference between the second cleaning part and the first cleaning part in the support cylinder is 0, both the first and second cleaning parts can contact the surface to be cleaned for cleaning a surface of one material. In this case, both the first and second cleaning parts serve as the primary cleaning structure. When the radial height of the second cleaning part in the support cylinder is greater than that of the first cleaning part, the second cleaning part can fully contact the surface to be cleaned, and can serve as the primary cleaning structure for cleaning a surface of another material. When the radial height of the second cleaning part in the support cylinder is less than that of the first cleaning part, the first cleaning part can fully contact the surface to be cleaned, and can serve as the primary cleaning structure for cleaning a surface of yet another material.

[0017] According to one embodiment of the present disclosure, when the second cleaning part is in the first position, the second cleaning part protrudes from the outer wall of the support cylinder by a larger dimension than the first cleaning part protrudes from the outer wall of the support cylinder along the radial direction of the support cylinder.

[0018] When the second cleaning part is in the second position, the size of the second cleaning part protruding from the outer wall of the support cylinder along the radial direction of the support cylinder is smaller than the size of the first cleaning part protruding from the outer wall of the support cylinder.

[0019] In this embodiment, when the second cleaning part is in the first position, the dimension by which the second cleaning part protrudes from the outer wall of the support cylinder is greater than the dimension by which the first cleaning part protrudes from the outer wall of the support cylinder. Therefore, the contact depth between the second cleaning part and the surface to be cleaned is greater than the contact depth between the first cleaning part and the surface to be cleaned. At this time, the second cleaning part can serve as the main cleaning structure of the roller brush for the surface to be cleaned.

[0020] For example, when cleaning soft surfaces such as carpets, the second cleaning part can be a squeegee. The second cleaning part can make deep contact with the soft surface to be cleaned, so as to roll out dirt deep under the carpet. At this time, the first cleaning part can contact the soft surface to be cleaned, or the first cleaning part can not contact the soft surface to be cleaned. This is not limited in the embodiments of this disclosure and can be set according to the usage requirements.

[0021] When the second cleaning section is in the second position, the dimension by which the second cleaning section protrudes from the outer wall of the support cylinder is smaller than the dimension by which the first cleaning section protrudes from the outer wall of the support cylinder. Therefore, the contact depth between the first cleaning section and the surface to be cleaned is greater than the contact depth between the second cleaning section and the surface to be cleaned. At this time, the first cleaning section can serve as the main cleaning structure of the roller brush for the surface to be cleaned.

[0022] For example, when cleaning hard surfaces such as floors and tiles, the first cleaning part can be a brush. The first cleaning part can pick up dirt from the hard surface and, under the action of suction, draw the dirt into the dust box. At this time, the second cleaning part can come into contact with the surface to be cleaned, or the second cleaning part can not come into contact with the surface to be cleaned. This is not limited in the embodiments of this disclosure and can be set according to the usage requirements.

[0023] According to one embodiment of the present disclosure, at least a portion of the drive assembly is located inside the support cylinder. The drive assembly includes a drive shaft and a reversing structure, the drive shaft and the reversing structure are connected, and the reversing structure is connected to the second cleaning section.

[0024] The drive shaft moves in conjunction with the reversing structure to make the second cleaning part move radially along the support cylinder.

[0025] In this embodiment of the present disclosure, the drive shaft can drive the second cleaning part to move radially along the support cylinder via a reversing structure, so that the second cleaning part has a first position and a second position. The reversing structure can be used to transmit the force of the drive shaft and enable the second cleaning part to move radially along the support cylinder.

[0026] According to one embodiment of this disclosure, the drive shaft can move axially along the support cylinder, and the reversing structure can move radially along the support cylinder;

[0027] The reversing structure is used to drive the second cleaning part to move radially between a first position and a second position along the support cylinder when the drive shaft moves axially along the support cylinder.

[0028] In this embodiment of the present disclosure, the axial movement of the drive shaft along the support cylinder provides a force for the movement of the second cleaning part. The reversing structure can be used to convert the force of the axial movement of the drive shaft along the support cylinder into a force for driving the second cleaning part to move radially along the support cylinder, so that the second cleaning part can move radially between a first position and a second position along the support cylinder.

[0029] According to one embodiment of the present disclosure, the reversing structure includes an adapter, one end of which is connected to a second cleaning section, and the other end of which is connected to a drive shaft;

[0030] The drive shaft moves in the forward direction along the axial direction of the support cylinder to move the second cleaning part toward the first position, and the drive shaft moves in the reverse direction along the axial direction of the support cylinder to move the second cleaning part toward the second position.

[0031] In this embodiment of the present disclosure, the drive shaft moves in the forward or reverse direction along the axial direction of the support cylinder, which can cause the second cleaning part to move in the direction of the first position or the second position. Therefore, the unidirectional movement of the drive shaft along the axial direction of the support cylinder can cause the second cleaning part to move in the radial direction of the support cylinder, thereby facilitating the driving of the movement direction of the second cleaning part and improving the stability of the coordinated movement between the drive shaft, the reversing structure and the second cleaning part.

[0032] According to one embodiment of the present disclosure, one of the drive shaft and the adapter is provided with a drive protrusion, and the other of the drive shaft and the adapter is provided with an inclined slide.

[0033] At least a portion of the drive protrusion is located within the inclined slide, so that when the drive shaft moves axially along the support cylinder, the adapter drives the second cleaning part to move radially along the support cylinder between a first position and a second position via the inclined slide.

[0034] In this embodiment of the present disclosure, by cooperating in the movement of the drive protrusion and the inclined slide, the force of the drive shaft moving axially along the support cylinder can be converted into a force on the second cleaning part moving radially along the support cylinder.

[0035] According to one embodiment of the present disclosure, the support cylinder is provided with a first limiting part, and the second cleaning part is provided with a second limiting part. The first limiting part and the second limiting part cooperate with each other to constrain the second cleaning part from moving radially along the support cylinder.

[0036] In this embodiment, the first and second limiting parts cooperate to constrain the movement direction of the second cleaning part, allowing it to move radially between a first and a second position along the support cylinder. The first and second limiting parts prevent the second cleaning part from easily deflecting in other directions during movement, thereby reducing the possibility of deflection deformation affecting the effective contact between the second cleaning surface and the surface to be cleaned, and consequently impacting the cleaning effect.

[0037] According to one embodiment of the present disclosure, one of the first limiting portion and the second limiting portion is a limiting protrusion, and the other of the first limiting portion and the second limiting portion is a limiting groove extending radially along the support cylinder.

[0038] In this embodiment, by providing a limiting groove extending radially along the support cylinder, the limiting protrusion can move radially within the limiting groove along the support cylinder. The limiting groove can guide the limiting protrusion radially along the support cylinder, ensuring that the second cleaning part can only move radially along the support cylinder. The second cleaning part is less likely to deflect in other directions, thereby improving the stability and reliability of the second cleaning part's radial movement along the support cylinder.

[0039] Furthermore, since the limiting groove extends radially along the support cylinder, the cooperation between the limiting protrusion and the limiting groove can also be used to constrain the distance of the second cleaning part's radial movement along the support cylinder.

[0040] According to one embodiment of this disclosure, it further includes a fixing member, the second cleaning part is connected to the support cylinder through the fixing member, the adapter is connected to the fixing member; and / or, the second limiting part is disposed on the fixing member.

[0041] In this embodiment, on the one hand, the fastener allows the second cleaning part to be stably connected to the support cylinder. On the other hand, the fastener can be used to provide structures such as adapters and second limiting parts to reduce the possibility that the second cleaning part is easily deformed due to direct connection between the adapters, second limiting parts, and other structures and the second cleaning part, thereby affecting the cleaning effect.

[0042] The fixing member and the second cleaning part can move synchronously. The fixing member can move radially along the support cylinder, thereby driving the second cleaning part to move radially along the support cylinder. Since the fixing member can slide radially along the support cylinder and can pass through the slot in the support cylinder, the fixing member ensures that the second cleaning part is less likely to rub against the inner wall of the slot in the support cylinder during its movement between the first and second positions. This reduces the possibility of damage to the second cleaning part due to friction and effectively protects it.

[0043] According to one embodiment of this disclosure, the drive assembly further includes a reset member disposed in the support cylinder and connected to the drive shaft; the reset member is used to drive the drive shaft to move in the opposite direction so that the second cleaning part moves in the direction of the second position.

[0044] In this embodiment, the forward movement of the drive shaft causes the second cleaning part to move toward the first position. A reset member can be used to reset the second cleaning part toward the second position.

[0045] In some examples, depending on the common application scenarios, the cleaning equipment is used more often on hard surfaces than on soft surfaces. Therefore, in the normal mode, the second cleaning unit can be located in the second position. The first cleaning unit can serve as the main cleaning structure. When cleaning a soft surface is required, the second cleaning unit can be adjusted to move towards the first position, making it the main cleaning structure. After cleaning the soft surface is complete, the second cleaning unit can be reset to the second position using a reset mechanism, and the first cleaning unit will once again serve as the main cleaning structure.

[0046] According to one embodiment of this disclosure, the drive assembly further includes a power source connected to the drive shaft; the power source is used to drive the drive shaft to move in the forward direction, so that the second cleaning part moves in the direction of the second position.

[0047] In this embodiment of the present disclosure, the power source can be used to provide driving force for the drive shaft to move axially in the forward direction along the support cylinder. Therefore, the drive shaft can cooperate with the inclined slide of the adapter, so that the adapter can drive the second cleaning part to move.

[0048] It is easy to understand that the driving forces exerted by the power source and the reset member on the drive shaft are in opposite directions. When the power source applies a positive force to the drive shaft, the reset member can undergo compressive deformation, and the second cleaning part can move to the first position. When the force exerted by the power source on the drive shaft is removed, the reset member can be used to drive the drive shaft to move in the opposite direction and reset, thereby allowing the second cleaning part to move to the second position.

[0049] According to one embodiment of this disclosure, along the axial direction of the support cylinder, the power source and the reset element are located at both ends of the drive shaft.

[0050] In this embodiment, the power source can provide power to one end of the drive shaft, so that the drive shaft can drive the second cleaning part to move radially toward the first position along the support cylinder via the reversing structure. The reset member can provide reset power to the other end of the drive shaft, so that the drive shaft can drive the second cleaning part to move radially toward the second position along the support cylinder via the reversing structure.

[0051] The power source and the reset component can be used to apply forces in opposite directions to the second cleaning part. Therefore, by setting the power source and the reset component at the two ends of the drive shaft respectively, it is convenient for the power source and the reset component to drive the drive shaft, which helps to improve the stability of the driving action of the power source and the reset component on the drive shaft.

[0052] According to one embodiment of the present disclosure, along the radial direction of the support cylinder, the roller brush includes at least one set of opposing second cleaning parts, each set of opposing second cleaning parts being connected to a drive shaft, the drive shaft driving the at least one set of opposing second cleaning parts to switch between a first position and a second position.

[0053] In this embodiment, the support cylinder may be provided with multiple second cleaning parts to improve the cleaning efficiency and effect on the surface to be cleaned. Furthermore, a single drive shaft can be used to drive at least one set of opposing second cleaning parts to move radially along the support cylinder. The overall structure is simple and does not require a large amount of space inside the support cylinder.

[0054] Secondly, this disclosure provides a cleaning device including the roller brush in any of the above embodiments.

[0055] Thirdly, this disclosure provides a cleaning system, including a base station and cleaning equipment. The cleaning equipment can be placed on the base station.

[0056] The beneficial effects of the roller brush provided in this disclosure are as follows: the first and second cleaning sections of the roller brush can be primarily used to clean surfaces of different materials. Therefore, when cleaning surfaces of different materials, the first and / or second cleaning sections on the roller brush can be switched to act on the surfaces to be cleaned, ensuring the contact depth between the roller brush and the surface to be cleaned, thereby improving the cleaning effect. Since the second cleaning section can move radially relative to the support cylinder, the first cleaning section can serve as the primary cleaning structure for cleaning the surface, achieving an optimal contact depth with the surface. Alternatively, the second cleaning section can serve as the primary cleaning structure for cleaning the surface, achieving an optimal contact depth with the surface. Alternatively, both the first and second cleaning sections can serve as primary cleaning structures for cleaning the surface, and both can contact the surface.

[0057] In addition to the technical problems solved by the embodiments of the present invention, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the roller brush, cleaning equipment, and cleaning system provided by the embodiments of the present invention, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further explained in detail in the specific embodiments.

[0076] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0077] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims. Clearly, the described embodiments are only a portion, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0078] The cleaning device provided in this disclosure can be a sweeper, floor scrubber, vacuum cleaner, etc. Taking a sweeper as an example, a sweeper is a device for cleaning floors. The cleaning function of a sweeper is mainly achieved through the high-speed rotation of a motor. The high-speed rotation of the motor can create a vacuum inside the machine, using high-speed airflow to agitate and sweep up dust, hair, debris, and other dirt from the floor and floor crevices, which is then sucked into the dust box by suction. The dirt can be accumulated in the bag filter or dust box for convenient regular cleaning by the user.

[0079] Some sweeping machines can also be equipped with a mop and a water tank for wiping the floor after sweeping, thereby further improving the cleaning effect. The cleaning equipment in this embodiment may only have sweeping functionality, or it may have a combination of sweeping and wiping functions; this is not limited in this embodiment.

[0080] Robotic vacuum cleaners can perform deep cleaning, including vacuuming, on floors, tiles, and carpets. The materials, surface properties, and roughness of these surfaces differ. Carpets have a soft surface, making it easy for dust, hair, and debris to embed deeply into them. The roller brush consists of rubber strips and bristles. The bristles are used to clean hard surfaces like floors and tiles. The rubber strips are used to better clean soft surfaces like carpets.

[0081] In related technologies, the height of the bristles is higher than the height of the rubber strip along the radial direction of the roller brush. When cleaning soft surfaces such as carpets, the rubber strip cannot make full contact with the carpet, resulting in poor cleaning ability for soft surfaces such as carpets.

[0082] Based on the aforementioned technical problems, the applicant has improved the structure of the existing roller brush. In this embodiment, the first cleaning part and the second cleaning part can be used to clean surfaces of different materials. The second cleaning part can have a first position and a second position along the radial direction of the support cylinder. Furthermore, the second cleaning part has a height difference between the first and second positions. Therefore, when cleaning surfaces of different materials, the height of the second cleaning part in the radial direction of the support cylinder can be adjusted to ensure sufficient contact and cleaning between the first and second cleaning parts and the surfaces of different materials, thereby guaranteeing the cleaning effect.

[0083] For example, when the first cleaning section is used to clean hard surfaces such as floors and tiles, and the second cleaning section is used to clean soft surfaces such as carpets, the height of the second cleaning section can be adjusted to ensure that the first cleaning section can make full contact with the hard surface when the roller brush is applied to it. Similarly, the height of the second cleaning section can be adjusted to ensure that the second cleaning section can make full contact with the soft surface when the roller brush is applied to it. Therefore, the roller brush provided in this embodiment can make full contact with surfaces of different materials when cleaning, which is beneficial for improving the cleaning effect on surfaces of different materials.

[0084] The roller brush 100, cleaning equipment, and cleaning system provided in this disclosure are described below with reference to the accompanying drawings and specific embodiments.

[0085] See Figures 1 to 6 As shown, the roller brush 100 of this embodiment includes a support cylinder 110, a first cleaning section 120, a second cleaning section 130, and a drive assembly 140.

[0086] The first cleaning section 120 is disposed on the support cylinder 110. Along the radial direction of the support cylinder 110 (e.g., ... Figures 3 to 6 In the Y direction of the support cylinder 110, at least a portion of the first cleaning part 120 protrudes from the outer wall of the support cylinder 110. Along the radial Y direction of the support cylinder 110, the second cleaning part 130 is movably connected to the support cylinder 110. The second cleaning part 130 has a first position and a second position.

[0087] The drive assembly 140 is connected to the second cleaning section 130. The drive assembly 140 is used to drive the second cleaning section 130 to move between a first position and a second position. The second cleaning section 130 has a height difference in size between the first position and the second position along the radial direction Y of the support cylinder 110.

[0088] It should be noted that the first cleaning section 120 and the second cleaning section 130 can refer to the cleaning structure on the roller brush 100 that contacts the surface to be cleaned for cleaning the surface.

[0089] In this embodiment, by setting a radial Y-shaped height difference between the dimensions of the second cleaning part 130 in the first position and its dimensions in the second position, the radial Y-shaped height of the second cleaning part 130 within the support cylinder 110 can be adjusted. Therefore, when cleaning the surface to be cleaned using the second cleaning part 130, the contact depth between the second cleaning part 130 and the surface to be cleaned is adjustable. By adjusting the second cleaning part 130 at different positions, the interference fit between the second cleaning part 130 and the surface to be cleaned can be adjusted, thereby improving the cleaning effect on the surface to be cleaned.

[0090] It should be noted that the adjustable interference fit between the second cleaning part 130 and the surface to be cleaned means that the second cleaning part 130 and the surface to be cleaned can have an interference fit. In this embodiment, the interference fit can be defined as sufficient contact between the second cleaning part 130 and the surface to be cleaned. When the second cleaning part 130 acts on the surface to be cleaned, there can be relative pressure between the second cleaning part 130 and the surface to be cleaned to clean stubborn stains on the surface to be cleaned, thereby improving the cleaning effect. It is easy to understand that when the second cleaning part 130 has a large interference fit with the surface to be cleaned, the second cleaning part 130 can undergo a certain deformation. For example, when the second cleaning part 130 is an adhesive strip, increasing the interference fit between the second cleaning part 130 and the surface to be cleaned can cause the second cleaning part 130 to deform, and the contact area between the second cleaning part 130 and the surface to be cleaned can be increased, thereby improving the cleaning effect and cleaning efficiency of the surface to be cleaned.

[0091] On the other hand, when cleaning an uneven surface, the contact depth between the second cleaning part 130 and the surface to be cleaned can maintain the optimal contact depth for cleaning, thereby improving the cleaning effect of the second cleaning part 130 on the surface to be cleaned.

[0092] Specifically, when cleaning a recessed surface, the height of the second cleaning part 130 along the radial direction Y of the support cylinder 110 can be increased to ensure sufficient contact between the second cleaning part 130 and the surface to be cleaned, thereby improving the cleaning effect on the recessed surface. When cleaning a raised surface, the height of the second cleaning part 130 along the radial direction Y of the support cylinder 110 can be decreased to prevent excessive contact between the second cleaning part 130 and the surface to be cleaned, thus reducing the possibility of excessive interference between the second cleaning part 130 and the surface to be cleaned, which could easily damage the second cleaning part 130.

[0093] Furthermore, when cleaning surfaces of different materials, the height of the second cleaning part 130 in the radial direction Y of the support cylinder 110 can be adjusted so that the cleaning structure on the roller brush 100 that contacts the surface to be cleaned is the first cleaning part 120 and / or the second cleaning part 130. This ensures that when the roller brush 100 cleans surfaces of different materials, it makes full contact with the surface to be cleaned through different cleaning structures, thereby improving the cleaning effect on surfaces of different materials.

[0094] The first cleaning part 120 may protrude from the outer wall of the support cylinder 110. Since the second cleaning part 130 has a first position and a second position along the radial direction Y of the support cylinder 110, and the first position and the second position have a height difference, a height difference can be created between the second cleaning part 130 and the first cleaning part 120. This height difference may be greater than or equal to 0.

[0095] Specifically, when the height difference between the second cleaning part 130 and the first cleaning part 120 in the radial Y direction of the support cylinder 110 is 0, both the first cleaning part 120 and the second cleaning part 130 can contact the surface to be cleaned for cleaning a surface of one material. In this case, both the first cleaning part 120 and the second cleaning part 130 serve as the main cleaning structure. When the height of the second cleaning part 130 in the radial Y direction of the support cylinder 110 is greater than the height of the first cleaning part 120 in the radial Y direction of the support cylinder 110, the second cleaning part 130 can fully contact the surface to be cleaned, and the second cleaning part 130 can serve as the main cleaning structure for cleaning a surface of another material. When the height of the second cleaning part 130 in the radial Y direction of the support cylinder 110 is less than the height of the first cleaning part 120 in the radial Y direction of the support cylinder 110, the first cleaning part 120 can fully contact the surface to be cleaned, and the first cleaning part 120 can serve as the main cleaning structure for cleaning a surface of yet another material.

[0096] In some examples, depending on the common application environment of the cleaning equipment, it is mainly used to clean hard surfaces such as floors and tiles, or soft surfaces such as carpets. Therefore, in this embodiment of the disclosure, it is described using an example where one of the first cleaning part 120 and the second cleaning part 130 is a brush bristle, and the other is a scraper. It should be noted that the first cleaning part 120 and the second cleaning part 130 may be, but are not limited to, brush bristles or a scraper.

[0097] The brush bristles are used to clean hard surfaces. They lift up dust, hair, and other dirt from hard surfaces and suck it into the dustbin. The scraper is used to clean soft surfaces. Because dust, hair, and other dirt tend to penetrate deep into soft surfaces, the scraper can press into these areas to lift them out and suck them into the dustbin.

[0098] It should be noted that when the first cleaning part 120 is a brush bristle and the second cleaning part 130 is a scraper, the drive assembly 140 can cause the scraper to have a first position and a second position in the radial direction Y of the support cylinder 110. When the first cleaning part 120 is a scraper and the second cleaning part 130 is a brush bristle, the drive assembly 140 can cause the brush bristle to have a first position and a second position in the radial direction Y of the support cylinder 110. No specific limitations are made in this disclosure. For ease of description, this disclosure will use the example of the first cleaning part 120 being a brush bristle and the second cleaning part 130 being a scraper as an example.

[0099] It is readily understood that, since the drive assembly 140 allows the second cleaning part 130 to move between a first position and a second position, where the first and second positions refer to two extreme positions of the second cleaning part 130 along the radial direction Y of the support cylinder 110, the drive assembly 140 can fix the second cleaning part 130 in the first and second positions, or fix it in any position between the first and second positions. Therefore, the position of the second cleaning part 130 in this embodiment is easy to control and adjust, and the second cleaning part 130 is less prone to deformation during its movement along the radial direction Y of the support cylinder 110, which is beneficial for improving the service life of the second cleaning part 130.

[0100] In some examples, the first cleaning section 120 and the second cleaning section 130 may be arranged at circumferential intervals along the support cylinder 110. The number of the first cleaning section 120 and the second cleaning section 130 may be, but is not limited to, one.

[0101] In some possible implementations, when the second cleaning part 130 is in the first position, the dimension by which the second cleaning part 130 protrudes from the outer wall of the support cylinder 110 along the radial Y direction is greater than the dimension by which the first cleaning part 120 protrudes from the outer wall of the support cylinder 110. When the second cleaning part 130 is in the second position, the dimension by which the second cleaning part 130 protrudes from the outer wall of the support cylinder 110 along the radial Y direction is smaller than the dimension by which the first cleaning part 120 protrudes from the outer wall of the support cylinder 110.

[0102] In this embodiment, when the second cleaning part 130 is in the first position, the dimension of the second cleaning part 130 protruding from the outer wall of the support cylinder 110 is greater than the dimension of the first cleaning part 120 protruding from the outer wall of the support cylinder 110. Therefore, the contact depth between the second cleaning part 130 and the surface to be cleaned is greater than the contact depth between the first cleaning part 120 and the surface to be cleaned. At this time, the second cleaning part 130 can serve as the main cleaning structure of the roller brush 100 for the surface to be cleaned.

[0103] For example, when cleaning soft surfaces such as carpets, the second cleaning section 130 can be a squeegee. The second cleaning section 130 can make deep contact with the soft surface to be cleaned, so as to roll out dirt that has penetrated to the bottom of the carpet. At this time, the first cleaning section 120 can contact the soft surface to be cleaned, or the first cleaning section 120 can not contact the soft surface to be cleaned. This is not limited in the embodiments disclosed herein and can be set according to the usage requirements.

[0104] When the second cleaning part 130 is in the second position, the dimension of the second cleaning part 130 protruding from the outer wall of the support cylinder 110 is smaller than the dimension of the first cleaning part 120 protruding from the outer wall of the support cylinder 110. Therefore, the contact depth between the first cleaning part 120 and the surface to be cleaned is greater than the contact depth between the second cleaning part 130 and the surface to be cleaned. At this time, the first cleaning part 120 can serve as the main cleaning structure of the roller brush 100 for the surface to be cleaned.

[0105] For example, when cleaning hard surfaces such as floors and tiles, the first cleaning section 120 can be a brush. The first cleaning section 120 can roll up the dirt on the hard surface and draw it into the dust box under the action of suction. At this time, the second cleaning section 130 can contact the surface to be cleaned, or the second cleaning section 130 can not contact the surface to be cleaned. This is not limited in the embodiments of this disclosure and can be set according to the usage requirements.

[0106] See also some of the possible implementation methods. Figure 2 , Figure 3 and Figure 5 As shown, at least a portion of the drive assembly 140 in this embodiment of the present disclosure is located within the support cylinder 110. The drive assembly 140 includes a drive shaft 141 and a reversing structure 142. The drive shaft 141 and the reversing structure 142 are connected, and the reversing structure 142 is connected to the second cleaning section 130. The drive shaft 141 and the reversing structure 142 cooperate to move, causing the second cleaning section 130 to move radially Y along the support cylinder 110.

[0107] In this embodiment of the present disclosure, the drive shaft 141 can drive the second cleaning part 130 to move radially Y-axis along the support cylinder 110 via the reversing structure 142, so that the second cleaning part 130 has a first position and a second position. The reversing structure 142 can be used to transmit the force of the drive shaft 141 and enable the second cleaning part 130 to move radially Y-axis along the support cylinder 110.

[0108] In some examples, the support cylinder 110 may have a slot 110b through which the second cleaning part 130 passes and slides. Part of the second cleaning part 130 may be located inside the support cylinder 110 for connection to the drive shaft 141. Part of the second cleaning part 130 may be located outside the support cylinder 110 for contact with the surface to be cleaned.

[0109] Specifically, the second cleaning part 130 can move away from the center of the support cylinder 110 along the radial direction Y of the support cylinder 110, which can cause the second cleaning part 130 to move towards the first position. When the second cleaning part 130 moves towards the center of the support cylinder 110, it can cause the second cleaning part 130 to move towards the second position.

[0110] See also some of the possible implementation methods. Figure 3 and Figure 4 As shown, in this embodiment of the present disclosure, the drive shaft 141 is movable along the axial direction X of the support cylinder 110. The reversing structure 142 is movable along the radial direction Y of the support cylinder 110. The reversing structure 142 can be used to drive the second cleaning part 130 to move along the radial direction Y of the support cylinder 110 between a first position and a second position when the drive shaft 141 moves along the axial direction X of the support cylinder 110.

[0111] In this embodiment of the present disclosure, the axial X-axis movement of the drive shaft 141 along the support cylinder 110 provides a force for the movement of the second cleaning part 130. The reversing structure 142 can be used to convert the force of the drive shaft 141 moving along the axial X-axis of the support cylinder 110 into a force driving the second cleaning part 130 to move along the radial Y-axis of the support cylinder 110, so that the second cleaning part 130 can move between a first position and a second position along the radial Y-axis of the support cylinder 110.

[0112] In some examples, the drive shaft 141 may be located in the central region of the support cylinder 110. In other words, the drive shaft 141 and the support cylinder 110 may be coaxially arranged.

[0113] See also some of the possible implementation methods. Figure 2 , Figure 3 and Figure 5 As shown, the reversing structure 142 of this embodiment includes an adapter 1421. One end of the adapter 1421 is connected to the second cleaning section 130, and the other end of the adapter 1421 is connected to the drive shaft 141.

[0114] The drive shaft 141 moves in the forward direction along the axial direction X of the support cylinder 110 to move the second cleaning part 130 toward the first position. The drive shaft 141 also moves in the reverse direction along the axial direction X of the support cylinder 110 to move the second cleaning part 130 toward the second position.

[0115] In this embodiment of the present disclosure, the drive shaft 141 moves in the forward or reverse direction along the axial direction X of the support cylinder 110, which can cause the second cleaning part 130 to move in the direction of the first position or the second position. Therefore, the unidirectional movement of the drive shaft 141 along the axial direction X of the support cylinder 110 can cause the second cleaning part 130 to move unidirectionally along the radial direction Y of the support cylinder 110, thereby facilitating the driving of the movement direction of the second cleaning part 130 and improving the stability of the coordinated movement between the drive shaft 141, the reversing structure 142 and the second cleaning part 130.

[0116] It should be noted that the forward or reverse movement of the drive shaft 141 along the axial direction X of the support cylinder 110 means that the drive shaft 141 can have two opposite directions of movement along the axial direction X of the support cylinder 110. (Reference) Figure 4 and Figure 6The direction shown indicates that the drive shaft 141 moving in the positive X direction along the support cylinder 110 can refer to the drive shaft moving to the left X direction. When the drive shaft moves to the left X direction, the second cleaning part 130 can move towards the first position through cooperation with the adapter 1421. When the drive shaft moves to the right X direction, the second cleaning part 130 can move towards the second position through cooperation with the adapter 1421.

[0117] See also some of the possible implementation methods. Figure 2 , Figure 4 and Figure 6 As shown, in this embodiment of the present disclosure, one of the drive shaft 141 and the adapter 1421 is provided with a drive protrusion 1411. The other of the drive shaft 141 and the adapter 1421 is provided with an inclined slide 1421a.

[0118] At least a portion of the drive protrusion 1411 is located within the inclined slide 1421a, so that when the drive shaft 141 moves along the axial direction X of the support cylinder 110, the adapter 1421 drives the second cleaning part 130 to move along the radial direction Y of the support cylinder 110 between a first position and a second position via the inclined slide 1421a.

[0119] In this embodiment of the present disclosure, by driving the protruding post 1411 and the inclined slide 1421a in coordination, the force of the drive shaft 141 moving axially (X) along the support cylinder 110 can be converted into a force of the second cleaning part 130 moving radially (Y) along the support cylinder 110.

[0120] The driving protrusion 1411 can be disposed on the driving shaft 141, and the inclined slide 1421a can be disposed on the adapter 1421. Alternatively, the driving protrusion 1411 can be disposed on the adapter 1421, and the inclined slide 1421a can be disposed on the driving shaft 141, which is not limited in this embodiment.

[0121] For ease of description, this embodiment is described using the example of a drive protrusion 1411 disposed on a drive shaft 141 and an inclined slide 1421a disposed on a connector 1421.

[0122] The inclined slide 1421a and the support cylinder 110 may have an inclined angle between their axial direction X and their radial direction Y.

[0123] Specifically, the inclined slide 1421a may have a first end 1401 and a second end 1402. Along the radial direction Y of the support cylinder 110, one of the first end 1401 and the second end 1402 may be closer to the axis of the drive shaft 141 than the other, to form the inclined slide 1421a. (Reference) Figure 4 and Figure 6As shown, along the radial Y direction of the support cylinder 110, the distance between the first end 1401 and the axis of the drive shaft 141 can be less than the distance between the second end 1402 and the axis of the drive shaft 141. When the drive shaft moves to the left along the X direction, the drive protrusion 1411 moves from the second end 1402 towards the first end 1401 along the inclined slide 1421a. Under the guiding action of the drive protrusion 1411 and the inclined slide 1421a, the drive protrusion 1411 can push against the inner wall of the inclined slide 1421a to move away from the axis of the support cylinder 110, so that the second cleaning part 130 can move away from the axis of the support cylinder 110 through the adapter 1421, thereby allowing the second cleaning part 130 to move outward along the radial Y direction of the support cylinder 110. In other words, the second cleaning part 130 can move towards the first position along the radial Y direction of the support cylinder 110.

[0124] Correspondingly, continue to refer to Figure 4 and Figure 6 As shown, when the drive axis moves to the right (X), the drive protrusion 1411 moves along the inclined slide 1421a from the first end 1401 to the second end 1402. Under the guiding action of the drive protrusion 1411 and the inclined slide 1421a, the drive protrusion 1411 can pull the inner wall of the inclined slide 1421a towards the axis of the support cylinder 110, so that the second cleaning part 130 can move towards the axis of the support cylinder 110 via the adapter 1421, thereby allowing the second cleaning part 130 to move inward along the radial direction (Y) of the support cylinder 110. In other words, the second cleaning part 130 can move towards the second position along the radial direction (Y) of the support cylinder 110.

[0125] In some examples, the reversing structure 142 may include multiple adapters 1421. The number of adapters 1421 may be set according to the extension length of the roller brush 100, and is not limited in this embodiment. Each adapter 1421 may be provided with an inclined slide 1421a. The number of inclined slides 1421a may match the number of drive protrusions 1411.

[0126] For example, when there are multiple adapters 1421, the multiple adapters 1421 can be arranged at X intervals along the axial direction of the support cylinder 110. Among them, the inclined slides 1421a on the multiple adapters 1421 arranged at X intervals along the axial direction of the support cylinder 110 have the same inclination direction.

[0127] In some examples, the adapter 1421 may also be provided with a straight slide 1421b that communicates with the inclined slide 1421a. The extension direction of the straight slide 1421b is parallel to the axial direction X of the support cylinder 110. The straight slide 1421b is connected to the second end 1402 of the inclined slide 1421a.

[0128] In some possible implementations, the support cylinder 110 is provided with a first limiting portion. The second cleaning portion 130 is provided with a second limiting portion. The first limiting portion and the second limiting portion cooperate with each other to constrain the second cleaning portion 130 to move radially Y along the support cylinder 110.

[0129] In this embodiment, the first and second limiting portions cooperate to constrain the movement direction of the second cleaning portion 130, allowing it to move between a first and a second position along the radial direction Y of the support cylinder 110. The first and second limiting portions prevent the second cleaning portion 130 from easily deflecting in other directions during movement, thereby reducing the possibility of deflection deformation that could affect the effective contact between the second cleaning surface and the surface to be cleaned, and consequently the cleaning effect.

[0130] See also some of the possible implementation methods. Figure 3 and Figure 5 As shown, in this embodiment of the present disclosure, one of the first limiting portion and the second limiting portion is a limiting protrusion 131. The other of the first limiting portion and the second limiting portion is a limiting groove 110a extending radially Y along the support cylinder 110.

[0131] In this embodiment, by providing a limiting groove 110a extending radially Y along the support cylinder 110, the limiting protrusion can move within the limiting groove 110a along the radially Y direction of the support cylinder 110. The limiting groove 110a can guide the limiting protrusion 131 along the radially Y direction of the support cylinder 110, so that the second cleaning part 130 can only move along the radially Y direction of the support cylinder 110. The second cleaning part 130 is less likely to deflect in other directions, thereby improving the stability and reliability of the second cleaning part 130's movement along the radially Y direction of the support cylinder 110.

[0132] Furthermore, since the limiting groove 110a extends radially Y along the support cylinder 110, the cooperation between the limiting protrusion 131 and the limiting groove 110a can also be used to constrain the distance that the second cleaning part 130 moves radially Y along the support cylinder 110.

[0133] In some examples, the inner wall of the support cylinder 110 may be provided with a limiting groove 110a, and the second cleaning part 130 may be provided with a limiting protrusion 131. Alternatively, the inner wall of the support cylinder 110 may be provided with a limiting protrusion 131, and the second cleaning part 130 may be provided with a limiting groove 110a, which is not limited in the embodiments disclosed herein.

[0134] When the limiting groove 110a is provided on the inner wall of the support cylinder 110, the limiting groove 110a and the inner wall of the support cylinder 110 have opposing wall surfaces along the radial direction Y of the support cylinder 110. The two opposing wall surfaces can be used to constrain the maximum distance of the limiting protrusion 131 along the radial direction Y of the support cylinder 110, thereby constraining the movement displacement of the second cleaning part 130 along the radial direction Y of the support cylinder 110.

[0135] See also some of the possible implementation methods. Figure 3 and Figure 5 As shown, the roller brush 100 of this embodiment further includes a fixing member 150. The second cleaning part 130 is connected to the support cylinder 110 via the fixing member 150. The adapter 1421 is connected to the fixing member 150. And / or, the second limiting part is provided on the fixing member 150.

[0136] In this embodiment, on the one hand, the fixing member 150 can stably connect the second cleaning part 130 to the support cylinder 110. On the other hand, the fixing member 150 can be used to set the adapter 1421, the second limiting part and other structures to reduce the possibility that the second cleaning part 130 is easily deformed due to the direct connection of the adapter 1421, the second limiting part and other structures to the second cleaning part 130, thereby affecting the cleaning effect.

[0137] The fixing member 150 and the second cleaning part 130 can move synchronously. The fixing member 150 can move radially Y along the support cylinder 110, thereby driving the second cleaning part 130 to move radially Y along the support cylinder 110. Since the fixing member 150 can slide radially Y along the support cylinder 110, and the fixing member 150 can pass through the slot 110b of the support cylinder 110, the fixing member 150 can prevent the second cleaning part 130 from rubbing against the inner wall of the slot 110b of the support cylinder 110 during the movement between the first position and the second position. This reduces the possibility of the second cleaning part 130 being easily damaged due to friction, and effectively protects the second cleaning part 130.

[0138] In some examples, this disclosure does not limit the method of fixing the second cleaning part 130 to the fastener 150. For example, the second cleaning part 130 and the fastener 150 may be connected by snap-fit, locking fastener, etc.

[0139] See also some of the possible implementation methods. Figure 4 and Figure 6 As shown, the drive assembly 140 also includes a reset member 160. The reset member 160 is disposed on the support cylinder 110 and is connected to the drive shaft 141. The reset member 160 is used to drive the drive shaft 141 to move in the opposite direction, so that the second cleaning part 130 moves in the direction of the second position.

[0140] In this embodiment, the forward movement of the drive shaft 141 causes the second cleaning part 130 to move toward the first position. The reset member 160 can be used to reset the second cleaning part 130 toward the second position.

[0141] In some examples, depending on the common application scenarios, the cleaning equipment is used more often on hard surfaces to be cleaned than on soft surfaces. Therefore, in the normal mode, the second cleaning unit 130 can be located in the second position. The first cleaning unit 120 can serve as the main cleaning structure. When cleaning a soft surface is required, the second cleaning unit 130 can be adjusted to move towards the first position, so that the second cleaning unit 130 serves as the main cleaning structure. After cleaning the soft surface is completed, the second cleaning unit 130 can be reset to the second position via the reset member 160, and the first cleaning unit 120 once again serves as the main cleaning structure.

[0142] In some examples, the reset element 160 may be, but is not limited to, an elastic element, such as a spring. When the drive shaft 141 moves in the forward direction, the reset element 160 may undergo elastic deformation and accumulate elastic potential energy. When the force of the forward movement of the drive shaft 141 is removed, the reset element 160 may release the elastic potential energy to cause the drive shaft 141 to move in the reverse direction.

[0143] In some implementations, the drive assembly 140 also includes a power source. The power source is connected to the drive shaft 141. The power source is used to drive the drive shaft 141 in a forward direction to move the second cleaning section 130 toward the second position.

[0144] In this embodiment of the present disclosure, the power source can be used to provide driving force for the drive shaft 141 to move in the positive X direction along the support cylinder 110. Therefore, the drive shaft 141 can cooperate with the inclined slide 1421a of the adapter 1421, so that the adapter 1421 can drive the second cleaning part 130 to move.

[0145] It is easy to understand that the driving forces exerted by the power source and the reset member 160 on the drive shaft 141 are in opposite directions. When the power source applies a forward force to the drive shaft 141, the reset member 160 can undergo compressive deformation, and the second cleaning part 130 can move to the first position. When the force exerted by the power source on the drive shaft 141 is removed, the reset member 160 can be used to drive the drive shaft 141 to move in the opposite direction and reset, thereby allowing the second cleaning part 130 to move to the second position.

[0146] It is easy to understand that by adjusting the axial X force exerted by the power source on the drive shaft 141 along the support cylinder 110, the second cleaning part 130 can be fixed at any position between the first position and the second position.

[0147] In some feasible configurations, along the axial direction X of the support cylinder 110, the power source and the reset element 160 are located at opposite ends of the drive shaft 141.

[0148] In this embodiment, the power source can provide power to one end of the drive shaft 141, so that the drive shaft 141 can drive the second cleaning part 130 to move in the radial Y direction of the support cylinder 110 towards the first position via the reversing structure 142. The reset member 160 can provide reset power to the other end of the drive shaft 141, so that the drive shaft 141 can drive the second cleaning part 130 to move in the radial Y direction of the support cylinder 110 towards the second position via the reversing structure 142.

[0149] The power source and reset member 160 can be used to apply forces in opposite directions to the second cleaning part 130. Therefore, by setting the power source and reset member 160 at the two ends of the drive shaft 141 respectively, the power source and reset member 160 can easily drive the drive shaft 141, which is beneficial to improving the stability of the driving action of the power source and reset member 160 on the drive shaft 141.

[0150] In some examples, along the axial direction X of the support cylinder 110, a first cover 170 and a second cover 180 may be provided at both ends of the support cylinder 110, respectively. The first cover 170 and the second cover 180 can cover both ends of the support cylinder 110 and can be used to fix the drive shaft 141.

[0151] In some examples, the reset member 160 may be located within the first cover 170. Along the axial direction X of the support cylinder 110, one end of the reset member 160 may abut against the inner wall of the first cover 170, and the other end may be connected to the drive shaft 141.

[0152] In some examples, the power source may be located on one side of the second cover 180. The end of the drive shaft 141 away from the reset member 160 may pass through the second cover 180 and be connected to the power source.

[0153] In some examples, the power source may be, but is not limited to, an electric motor. The power source can provide power to the drive shaft 141 via a transmission assembly. For example, the transmission assembly may include a lead screw and a slider.

[0154] See also some of the possible implementation methods. Figure 3 and Figure 5 As shown, along the radial direction Y of the support cylinder 110, the roller brush 100 includes at least one set of opposing second cleaning sections 130. Each of the at least one set of opposing second cleaning sections 130 is connected to a drive shaft 141. The drive shaft 141 drives the at least one set of opposing second cleaning sections 130 to switch between a first position and a second position.

[0155] In this embodiment, the support cylinder 110 may be provided with a plurality of second cleaning parts 130 to improve the cleaning efficiency and cleaning effect on the surface to be cleaned. Furthermore, a drive shaft 141 can be used to drive at least one set of opposing second cleaning parts 130 to move radially Y along the support cylinder 110. The overall structure is simple and does not occupy a large amount of space inside the support cylinder 110.

[0156] In some examples, drive protrusions 1411 may be provided on both sides of the drive shaft 141 along the radial direction Y of the support cylinder 110. Correspondingly, adapters 1421 corresponding to the drive protrusions 1411 are provided on both sides of the drive shaft 141, and inclined slides 1421a are provided on the adapters 1421. Among them, the inclined directions of the inclined slides 1421a on both sides of the drive shaft 141 are opposite along the radial direction Y of the support cylinder 110.

[0157] In some examples, along the radial Y of the support cylinder 110, the drive protrusions 1411 located on both sides of the drive shaft 141 can be staggered in the axial X of the support cylinder 110.

[0158] This disclosure provides a cleaning device, which may include the roller brush 100 in any of the above embodiments.

[0159] In this embodiment, the first cleaning portion 120 and the second cleaning portion 130 of the roller brush 100 can be mainly used to clean surfaces of different materials. Therefore, when cleaning surfaces of different materials, the first cleaning portion 120 and / or the second cleaning portion 130 on the roller brush 100 can be switched to act on the surface to be cleaned to ensure the contact depth between the roller brush 100 and the surface to be cleaned, thereby improving the cleaning effect. Since the second cleaning portion 130 can move radially Y relative to the support cylinder 110, the first cleaning portion 120 can serve as the main cleaning structure to clean the surface, and the first cleaning portion 120 and the surface to be cleaned can have an optimal contact depth. Alternatively, the second cleaning portion 130 can serve as the main cleaning structure to clean the surface, and the second cleaning portion 130 and the surface to be cleaned can have an optimal contact depth. Alternatively, both the first cleaning portion 120 and the second cleaning portion 130 can serve as the main cleaning structure to clean the surface, and both the first cleaning portion 120 and the second cleaning portion 130 can contact the surface to be cleaned.

[0160] This disclosure provides a cleaning system that may include a base station and cleaning equipment. The cleaning equipment may be placed on the base station.

[0161] The base station can have a charging function. When cleaning equipment is placed on the base station, the base station can charge the cleaning equipment.

[0162] Base stations can also have cleaning functions. When cleaning equipment is placed on a base station, it can clean the cleaning modules such as the roller brush 100, rags, and side brushes on the cleaning equipment.

[0163] It should be noted that the numerical values ​​and ranges involved in this disclosure are approximate values. Due to the influence of the manufacturing process, there may be a certain range of errors, which can be considered negligible by those skilled in the art.

[0164] In the description of the embodiments of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.
