Description

Technical Field

[0001] This application relates to the field of cleaning appliance technology, and more particularly to a floor brush structure and cleaning equipment. Background Technology

[0002] In related technologies, cleaning equipment includes a floor brush, a fan assembly, and a dust cup assembly. The fan assembly is connected to the dust cup assembly, thereby providing negative pressure suction to the dust cup assembly. The dust cup assembly is used to collect dirt. The floor brush has a suction chamber on the side facing the ground, and the suction chamber is open on the side facing the ground to form a suction port. The suction port is connected to the dust cup assembly. When the cleaning equipment is working, the floor brush contacts the ground, and the dirt on the ground can be carried by the airflow and then sucked into the dust cup assembly from the suction port.

[0003] However, after the dirt is sucked in through the suction port, it needs to pass through the tortuous air duct before entering the dust cup assembly. This results in the airflow not being smooth enough, causing debris and other dirt to get stuck in the air duct, thus preventing the debris and other dirt from being smoothly sucked into the dust cup assembly. Utility Model Content

[0004] Based on this, this application provides a floor brush structure and cleaning device to solve the problem of easy clogging in cleaning devices in related technologies.

[0005] In a first aspect, this application provides a floor brush structure, comprising:

[0006] The housing has a placement surface configured to contact the surface to be cleaned, and a suction port is provided on one side of the housing with the placement surface.

[0007] The dust cup assembly has a first air inlet, and a straight air duct is formed between the dust suction port and the first air inlet.

[0008] The floor brush structure of this embodiment includes a housing and a dust cup assembly. The housing includes a placement surface and a suction port, and the dust cup assembly includes a first air inlet. By providing a placement surface for contact with the surface to be cleaned, and by providing a suction port on the side of the housing facing the surface to be cleaned, airflow carries dirt from the suction port into the dust cup assembly. By providing a first air inlet on the dust cup assembly and forming an air duct between the suction port and the first air inlet, the suction port is connected to the dust cup assembly through the air duct. Since the air duct is straight, the flow path of fluid from the suction port to the first air inlet is shortened, thereby promoting smooth flow of fluid from the suction port to the first air inlet along a straight path and reducing suction loss in the floor brush structure. This ensures that dirt can be smoothly sucked into the dust cup assembly, thereby improving the dust collection effect of the floor brush structure.

[0009] In one possible implementation, the housing also has a first air outlet located in the air duct and between the dust inlet and the first air inlet.

[0010] In this way, the fluid can flow sequentially along the suction port, the first air outlet, and the first air inlet into the dust cup assembly.

[0011] In one possible implementation, the first air inlet and the first air outlet are positioned opposite each other and abut against each other.

[0012] In this way, the first air inlet and the first air outlet can be directly connected, and the air duct and the dust cup assembly can be directly connected. This eliminates the need for intermediate pipes in related technologies, thereby shortening the flow path of dirt from the surface to be cleaned to the dust cup assembly, improving the dust collection effect of the floor brush structure. Furthermore, it prevents dirt from accumulating and getting stuck in the intermediate pipe, allowing the cleaning equipment to continuously collect dust and preventing the cleaning equipment from experiencing a decrease in suction power due to blockage.

[0013] In one possible implementation, the floor brush structure further includes a first seal located between the first air outlet and the first air inlet, and connected to one of the housing and the dust collection cup to seal the gap between the first air outlet and the first air inlet.

[0014] Thus, when the dust collection cup is installed into the housing and the first air outlet and the first air inlet come into contact, the first seal can come into contact between the first air outlet and the first air inlet, sealing the gap between the first air outlet and the first air inlet to prevent fluid from leaking from the gap between the first air outlet and the first air inlet, thereby improving the suction power of the floor brush structure and thus improving the dust collection effect of the floor brush structure.

[0015] In one possible implementation, the housing also has a first sealing groove surrounding the outer periphery of the first air outlet.

[0016] The first sealing element is disposed in the first sealing groove and abuts against the dust collection cup.

[0017] Thus, by setting a first sealing groove on the housing, and then setting the first sealing element in the first sealing groove, and then fixing the first sealing element on the housing, and setting the first sealing groove on the periphery of the first air outlet, the first sealing element can be made to abut between the first air outlet and the first air inlet each time the dust collection cup is installed into the housing, thereby improving the sealing performance of the floor brush structure.

[0018] In one possible implementation, there is an angle between the direction of travel of the air duct and the brush structure, the angle being greater than or equal to 15° and less than or equal to 45°.

[0019] This allows the air duct to be tilted relative to the placement surface, which in turn facilitates the formation of an airflow that is tilted towards the surface to be cleaned. This optimizes the airflow path of the floor brush structure, thereby improving its suction power. While creating an air duct of appropriate length, it also allows for better control of the floor brush structure's height, preventing it from becoming too large. An appropriately long air duct also results in a shorter fluid flow path and better dust collection.

[0020] In one possible implementation, along the extension direction of the air duct, the minimum distance from the first air inlet to the placement surface is greater than or equal to 15 mm, and the minimum distance from the first air inlet to the placement surface is less than or equal to 30 mm.

[0021] This facilitates the formation of an air duct of suitable length, allowing the gas to effectively remove dirt from the surface to be cleaned, and also shortens the flow path of dirt from the surface to the dust collection chamber, thereby improving the dust collection effect of the floor brush structure.

[0022] In one possible implementation, the dust collection cup is barrel-shaped, the inner wall of the dust collection cup defines a dust collection chamber, the first air inlet is located on the side wall of the dust collection cup, and the first air inlet is tangent to the circumference of the dust collection cup.

[0023] The first air inlet is located in the middle of the dust collection cup in the axial direction.

[0024] This allows the fluid on both sides of the suction port to converge towards the center of the suction port, and then enter the dust collection chamber through the first air outlet and the first air inlet in sequence.

[0025] In one possible implementation, the housing has a mounting groove, at least part of the dust collection cup is located in the mounting groove, and the first air outlet is located at the bottom of the mounting groove.

[0026] This design helps reduce the overall height of the floor brush structure, thus reducing its volume. Furthermore, placing the first air outlet at the bottom of the mounting groove helps reduce the distance between the first air outlet and the placement surface, which in turn helps reduce the distance between the first air inlet and the surface to be cleaned.

[0027] In one possible implementation, the dust cup assembly further includes a locking release element connected to at least one end of the dust cup;

[0028] The mounting slot is equipped with a locking part, and the locking release part is connected to the locking part to lock the dust collection cup in the mounting slot.

[0029] Thus, when the locking release component is connected to the locking part, the dust cup assembly can be locked onto the housing to prevent the dust cup from moving relative to the housing, and the first air inlet and the second air inlet can be directly connected. When the locking release component is disconnected from the locking part, the dust cup assembly can be removed from the housing to facilitate cleaning of the dust cup.

[0030] In one possible implementation, the outer side of the dust collection cup also has a first positioning part, the locking release member and the first positioning part are located at both ends of the dust collection cup, and the mounting groove is also provided with a second positioning part, with the first positioning part connected to the second positioning part.

[0031] Thus, through the cooperation of the first positioning part and the second positioning part, one end of the dust collection cup can be connected to the housing, and through the cooperation of the locking release part and the locking part, the other end of the dust collection cup can also be connected to the housing, thereby effectively restricting the position of the dust collection cup, preventing the dust collection cup from rotating relative to the housing, and ensuring that the first air inlet and the second air outlet are accurately aligned.

[0032] In one possible implementation, the dust cup assembly further includes a cyclone cone disposed in the dust collection chamber, with the axial direction of the cyclone cone parallel to the axial direction of the dust collection cup, and the axial direction of the cyclone cone parallel to the placement surface.

[0033] In this way, the dust cup assembly can be horizontally mounted on the housing to facilitate the connection between the first air inlet and the first air outlet, and to reduce the overall height of the floor brush structure, thereby reducing the volume of the floor brush structure.

[0034] In one possible implementation, the housing also has an air cavity configured to be connected to the main unit of the cleaning equipment;

[0035] The air chamber has a second air inlet, and the dust collection chamber has a second air outlet. The second air outlet and the second air inlet are arranged opposite to each other and abut against each other to connect the dust collection chamber and the air chamber.

[0036] Thus, since the second air outlet is connected to the second air inlet, the dust collection chamber and the air chamber can be connected, thereby connecting the air duct, dust collection chamber, air chamber, and main unit in sequence. This facilitates the main unit driving the fluid to flow sequentially along the air duct, dust collection chamber, air chamber, and main unit. Furthermore, the second air outlet and the second air inlet can be directly connected, thereby shortening the flow path of the fluid from the dust collection chamber to the air chamber.

[0037] In one possible implementation, the floor brush structure further includes a second seal that abuts against the second air inlet and the second air outlet to seal the gap between the second air inlet and the second air outlet.

[0038] Thus, when the dust collection cup is installed into the housing and the second air inlet and the second air outlet come into contact, the second seal can abut between the second air inlet and the second air outlet to seal the gap between the second air inlet and the second air outlet, thereby preventing fluid from leaking from the gap between the second air inlet and the second air outlet, thereby improving the suction power of the floor brush structure and thus improving the dust collection effect of the floor brush structure.

[0039] In one possible implementation, the housing has a second sealing groove surrounding the outer periphery of the second air inlet, and a second seal is disposed in the second sealing groove and abuts against the dust collection cup.

[0040] Thus, by setting a second sealing groove on the housing and placing the second sealing element in the second sealing groove, the second sealing element can be fixed on the housing. Furthermore, by placing the second sealing groove on the outer periphery of the second air inlet, when the dust collection cup is installed onto the housing, the second sealing element can accurately abut between the second air inlet and the second air outlet, thereby improving the sealing effect of the second sealing element.

[0041] In one possible implementation, the housing includes a top cover and a bottom cover, which are connected to define an air outlet cavity together.

[0042] The air duct is located on the side of the bottom shell away from the top cover, and the mounting groove is located on the side of the top cover away from the bottom shell.

[0043] Thus, the top cover and bottom shell can be processed and shaped separately before being assembled into a housing, which facilitates the processing and assembly of the housing. In one possible implementation, the floor brush structure also includes a connecting pipe, one end of which is configured to be connected to the main unit of the cleaning device, and the other end of which is connected to the air chamber.

[0044] In this way, the dust collection chamber and the air chamber can be connected, and the air duct, dust collection chamber, air chamber, connecting pipe and main unit can be connected in sequence, which makes it easier for the main unit to drive the fluid to flow in sequence along the air duct, dust collection chamber, air chamber, connecting pipe and main unit.

[0045] In one possible implementation, the floor brush structure also includes a guide element, the air cavity has a third air outlet, the connecting pipe has a third air inlet, and the third air outlet is connected to the third air inlet.

[0046] The third air inlet is connected to the third air outlet through a guide member, which is configured to guide the fluid to flow axially along the third air inlet.

[0047] Thus, when the fluid flows from the side of the air chamber away from the third air outlet toward the third air outlet, the guide can guide the fluid to flow axially along the third air inlet, thereby preventing the fluid from rotating circumferentially along the third air inlet, and thus preventing the formation of a cyclone at the junction of the third air outlet and the third air inlet. This reduces the energy loss of the floor brush structure and the load on the fan components, thereby improving the working efficiency and cleaning effect of the cleaning equipment.

[0048] Secondly, this application provides a cleaning device, including a main unit and the floor brush structure provided in the first aspect, wherein the floor brush structure is connected to the main unit.

[0080] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0081] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0082] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0083] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0084] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.

[0085] In related technologies, cleaning equipment includes a floor brush, a fan assembly, and a dust cup assembly. The fan assembly is connected to the dust cup assembly, thereby providing negative pressure suction to the dust cup assembly. The dust cup assembly is used to collect dirt. The floor brush has a suction chamber on the side facing the ground, and the suction chamber is open on the side facing the ground to form a suction port. The suction port is connected to the dust cup assembly. When the cleaning equipment is working, the floor brush contacts the ground, and the dirt on the ground can be carried by the airflow and then sucked into the dust cup assembly from the suction port.

[0086] However, after the dirt is sucked in through the suction port, it needs to pass through the tortuous air duct before entering the dust cup assembly. This results in the airflow not being smooth enough, causing debris and other dirt to get stuck in the air duct, thus preventing the debris and other dirt from being smoothly sucked into the dust cup assembly.

[0087] The following combination Figures 1 to 20 The specific implementation methods of the floor brush structure and cleaning equipment provided in the embodiments of this application will be described in detail.

[0088] Reference Figures 1 to 6 As shown in the figure, this application embodiment provides a cleaning device, which includes a main unit 20 and a floor brush structure 10, the floor brush structure 10 being connected to the main unit 20.

[0089] The main unit 20 may include a cover 201, a fan assembly 202, a handle 203, and a battery assembly 204. The fan assembly 202 is used to provide negative pressure suction, and the battery assembly 204 is used to power the fan assembly 202. The fan assembly 202 and the battery assembly 204 are disposed inside the cover 201. The handle 203 is inserted into the cover 201 and connected to the cover 201, so that the user can move the main unit 20 and the floor brush together by operating the handle 203.

[0090] Alternatively, in some embodiments, the fan assembly 202 may also be integrated onto the floor brush structure 10.

[0091] Reference Figures 2 to 12 As shown, based on the above embodiments, this application also provides a floor brush structure 10, which includes a housing 100 and a dust cup assembly 200. The housing 100 has a placement surface for contacting the surface to be cleaned. A suction port 111 is provided on one side of the housing 100 with the placement surface, and a first air outlet 112 is provided on the side of the housing 100 away from the placement surface. The suction port 111 and the first air outlet 112 are connected.

[0092] The dust cup assembly 200 includes a dust collection cup 210, which has a dust collection chamber 211. The dust collection chamber 211 has a first air inlet 2111. A straight air duct 110 can be formed between the first air inlet 2111 and the suction port 111, that is, the first air inlet 2111 and the suction port 111 can be connected in a straight line, and the fluid flows along this straight path in the air duct 110. The fluid flow path of the floor brush structure 10 can be found in [reference needed]. Figure 10 As shown.

[0093] The first air outlet 112 is positioned opposite to and abuts against the first air inlet 2111 so that the dust collection chamber 211 is connected to the air duct 110.

[0094] In this embodiment, the housing 100 is used to define part or all of the air duct 110, thereby guiding fluid to flow along the air duct 110 to the dust cup assembly 200, and the housing 100 can be used to install the dust cup assembly 200, which is detachably connected to the housing 100 to facilitate cleaning of the dust cup assembly 200.

[0095] Understandably, when the ground brush structure 10 cleans the surface to be cleaned, the placement surface is in contact with the surface to be cleaned. The air duct 110 has a dust suction port 111 and a first air outlet 112 on both sides. The air duct 110 is open on the side facing the surface to be cleaned to form the dust suction port 111. The dust suction port 111 is positioned opposite to the surface to be cleaned, so that the dirt on the surface to be cleaned is sucked into the air duct 110 from the dust suction port 111.

[0096] The dust collection chamber 211 has a first air inlet 2111, which is opposite to the first air outlet 112 and the two directly abut against each other. This allows dirt sucked into the air duct 110 to flow from the first air outlet 112 along a straight path to the first air inlet 2111, and then be sucked into the dust collection chamber 211. This arrangement can shorten the flow path of dirt from the surface to be cleaned to the dust collection cup 210, thereby improving the dust collection effect of the cleaning equipment. In addition, the intermediate pipe in the related technology can be eliminated, thereby avoiding dirt from being stuck in the intermediate pipe due to accumulation. This allows the cleaning equipment to continuously collect dust and prevents the cleaning equipment from losing suction power due to blockage.

[0097] It should be noted that mixtures of impurities such as gas, water stains, dust, and particles can be collectively referred to as fluids.

[0098] The floor brush structure 10 of this embodiment includes a housing 100 and a dust cup assembly 200. The housing 100 includes an air duct 110, a suction port 111, and a first air outlet 112. The dust cup assembly 200 includes a dust collection cup 210, a dust collection chamber 211, and a first air inlet 2111. By setting the air duct 110, the suction power is concentrated in a small area, allowing the air duct 110 to more effectively suck up dirt from the corresponding surface to be cleaned. The suction port 111 allows dirt from the surface to be cleaned to enter the air duct 110. The first air outlet 112 and the first air inlet 2111 connect the air duct 110 and the dust collection chamber 211, allowing dirt to continue flowing into the dust collection chamber 211 under negative pressure suction, thereby collecting the dirt in the dust collection cup 210. Because the first air inlet 2111 and the first air outlet 112 are arranged opposite to each other and abut against each other, the first air inlet 2111 and the first air outlet 112 can be directly connected, and the air duct 110 and the dust collection chamber 211 can be directly connected. This eliminates the need for intermediate pipes in related technologies, shortens the flow path of dirt from the surface to be cleaned to the dust collection cup 210, improves the suction effect of the floor brush structure 10, and prevents dirt from accumulating and getting stuck in the intermediate pipe. This allows the cleaning equipment to continuously suction and prevents the cleaning equipment from experiencing a decrease in suction power due to blockage. Therefore, the floor brush structure 10 of this embodiment has a better cleaning effect.

[0099] Reference Figures 4 to 6 , Figure 13 As shown, in one possible implementation, the floor brush structure 10 further includes a first seal 300 located between the first air outlet 112 and the first air inlet 2111, and connected to one of the housing 100 and the dust collection cup 210 to seal the gap between the first air outlet 112 and the first air inlet 2111.

[0100] Thus, when the dust collection cup 210 is installed into the housing 100, and the first air outlet 112 and the first air inlet 2111 come into contact, the first sealing member 300 can abut between the first air outlet 112 and the first air inlet 2111. The first sealing member 300 can seal the gap between the first air outlet 112 and the first air inlet 2111 to prevent fluid from leaking from the gap between the first air outlet 112 and the first air inlet 2111, thereby improving the suction power of the floor brush structure 10 and thus improving the dust collection effect of the floor brush structure 10.

[0101] Reference Figures 4 to 6 , Figure 13As shown, in some embodiments, the housing 100 further has a first sealing groove 120, which surrounds the outer periphery of the first air outlet 112. A first sealing member 300 is disposed in the first sealing groove 120 and abuts against the outer wall of the dust collection cup 210.

[0102] Understandably, since the dust cup assembly 200 needs to be cleaned frequently, it needs to be frequently removed from and installed on the housing 100. In order to effectively fix the first seal 300, a first sealing groove 120 can be provided on the housing 100, and the first seal 300 can be placed in the first sealing groove 120, thereby fixing the first seal 300 on the housing 100. The first sealing groove 120 is located on the periphery of the first air outlet 112. In this way, each time the dust cup 210 is installed on the housing 100, the first seal 300 can be abutted between the first air outlet 112 and the first air inlet 2111, thereby improving the sealing performance of the floor brush structure 10.

[0103] In some embodiments, the suction port 111 and the first air inlet 2111 are on the same straight line, or the suction port 111, the first air outlet 112, and the first air inlet 2111 are on the same straight line. This allows dirt on the surface to be cleaned to flow along a straight path into the dust collection chamber 211, shortening the flow path of the dirt and preventing dirt from getting stuck in other parts of the air duct 110. Furthermore, since the first air outlet 112 and the first air inlet 2111 are on the same straight line, it is beneficial for the first air outlet 112 and the first air inlet 2111 to be arranged opposite each other and abut against each other, thereby allowing the dust collection chamber 211 and the air duct 110 to be directly connected.

[0104] In one possible implementation, the suction port 111 is positioned relative to the first air inlet 2111 at the front end of the brush structure 10 in the direction of travel.

[0105] Thus, when the floor brush structure 10 moves forward along its direction of travel, since the suction port 111 is located at the front end of the floor brush structure 10, it is advantageous for external air to enter the suction port 111 from the front end of the floor brush structure 10. When flowing towards the rear end of the floor brush structure 10, it can flow towards the dust cup assembly 200 along the setting direction of the suction port 111 and the first air inlet 2111, thereby driving the dirt into the dust cup assembly 200 through the gas.

[0106] In one possible implementation, the air duct 110 and the direction of travel of the floor brush structure 10 have an angle greater than or equal to 15° and less than or equal to 45°.

[0107] The floor brush structure 10 travels along the X direction, the air duct 110 extends along the Y direction, and the height direction of the floor brush structure 10 can be referenced. Figure 11In the Z direction, the included angle is the angle between the X and Y directions, denoted as θ. For details, please refer to [reference needed]. Figure 11 As shown.

[0108] It is understandable that if the included angle θ is less than 15°, the first air inlet 2111 will be closer to the placement surface in the Y direction, which is not conducive to forming an air duct 110 on the side of the floor brush structure 10 close to the placement surface. Furthermore, the air duct 110 is almost parallel to the placement surface, which is not conducive to forming an airflow that is inclined relative to the surface to be cleaned. Consequently, it is not conducive to the airflow carrying away dirt from the surface to be cleaned, thus not conducive to improving the dust collection effect of the floor brush structure 10.

[0109] If the included angle θ is greater than 45°, the first air inlet 2111 will be too high relative to the placement surface, thereby increasing the height of the floor brush structure 10. Furthermore, when the fluid flows into the dust cup assembly 200 after entering the air duct 110, the fluid will flow upwards towards the floor brush structure 10, causing the fluid to flow radially along the dust cup assembly 200 instead of entering the dust cup assembly 200 tangentially. This will reduce the dust collection effect and dust-air separation effect of the floor brush structure 10.

[0110] Therefore, in this embodiment, controlling the included angle θ between 15° and 45° allows the air duct 110 to be inclined relative to the placement surface, which is beneficial for forming an airflow that is inclined relative to the surface to be cleaned. This, in turn, helps optimize the airflow path of the floor brush structure, thereby improving the suction power of the floor brush structure 10. Furthermore, while forming an air duct 110 of appropriate length, the height of the floor brush structure 10 can also be better controlled to prevent the floor brush structure 10 from becoming too large. An air duct 110 of appropriate length allows for a shorter fluid flow path and better dust collection. Moreover, an included angle θ between 15° and 45° also facilitates the fluid to enter the first air inlet 2111 tangentially along the dust cup assembly 200, thereby improving the dust collection and dust-air separation effects of the floor brush structure 10.

[0111] The included angle θ can be any one of 15°, 18°, 20°, 25°, 30°, 40°, and 45°, or fall within the range of any two of them.

[0112] For example, when the included angle θ is 25°, a suitable length of air duct 110 can be formed without changing the height of the floor brush structure 10 of the related technology, and the air duct 110 can be set at an angle relative to the placement surface, so that the gas can fully carry away the dirt on the surface to be cleaned, and the suction loss of the floor brush structure 10 is small. It can also make the fluid flow into the dust cup assembly 200 tangentially, thereby improving the dust collection effect of the floor brush structure 10 and improving the compactness of the floor brush structure 10.

[0113] In one possible implementation, the housing 100 has a placement surface configured to contact the surface to be cleaned. A suction port 111 is located on the side of the housing 100 facing the placement surface, and a first air outlet 112 is located on the side of the housing 100 away from the placement surface. Along the orientation of the first air inlet 2111 and the suction port 111, i.e., along the Y direction, the minimum distance from the first air inlet 2111 to the placement surface is greater than or equal to 15 mm, and less than or equal to 30 mm. The minimum distance from the first air inlet 2111 to the placement surface can be referenced... Figure 11 The marker D in the text.

[0114] Understandably, if the minimum distance from the first air inlet 2111 to the placement surface is less than 15 mm, the length of the air duct 110 will be too short, which will make it difficult to form an air duct 110 of appropriate length. Consequently, the gas will not be able to effectively carry away the dirt on the surface to be cleaned. If the distance from the first air inlet 2111 to the placement surface is greater than 30 mm, the flow path of the dirt to the dust collection chamber 211 will be too long.

[0115] Therefore, in this embodiment, the minimum distance from the first air inlet 2111 to the placement surface is controlled between 15 mm and 30 mm, which is conducive to forming an air duct 110 of appropriate length so that the gas can fully carry away the dirt on the surface to be cleaned, and also helps to shorten the flow path of the dirt on the surface to be cleaned to the dust collection chamber 211, thereby improving the dust collection effect of the floor brush structure 10.

[0116] The minimum distance D from the first air inlet 2111 to the placement surface can be any one of 15mm, 20mm, 22mm, 25mm, or 30mm, or within the range of any two.

[0117] For example, the minimum distance D from the first air inlet 2111 to the placement surface can be 20 mm. When the height from the first air inlet 2111 to the placement surface is the same as in the related technology, the included angle θ can be about 25°, which is conducive to the fluid entering the dust collection chamber 211 tangentially along the dust collection cup 210, and the fluid flows in a straight line from the suction port 111 to the first air inlet 2111, and the flow path between the two is short, so as to improve the dust collection effect of the floor brush structure 10.

[0118] It should be noted that since the first air inlet 2111 and the first air outlet 112 are directly connected, the distance from the first air outlet 112 to the dust suction port 111 along the Y direction can be between 15 mm and 30 mm. The distance from the first air inlet 2111 to the placement surface and the distance from the first air outlet 112 to the dust suction port 111 differ by 1.5 mm to 2 mm.

[0119] In some embodiments, the dust collection cup 210 is barrel-shaped, and the inner wall of the dust collection cup 210 defines a dust collection chamber 211. The first air inlet 2111 is located on the side wall of the dust collection cup 210 and is tangent to the circumference of the dust collection cup 210. The first air inlet 2111 is located at the center of the dust collection cup 210 in the axial direction.

[0120] It is understandable that the air duct 110 can be set along the left and right direction of the floor brush structure 10, thereby forming a longer dust suction port 111. The axial direction of the dust collection cup 210 can be consistent with the left and right direction of the floor brush structure 10. When the first air inlet 2111 is set in the middle of the axial direction of the dust collection cup 210, it is beneficial for the fluid on both sides of the dust suction port 111 to gather towards the middle of the air duct 110, and then enter the dust collection chamber 211 through the first air outlet 112 and the first air inlet 2111 in sequence.

[0121] Reference Figure 3 , Figure 4 , Figure 13 , Figure 16 and Figure 17 As shown, in one possible implementation, the housing 100 has a mounting groove 130, at least a portion of the dust collection cup 210 is located within the mounting groove 130, and the first air outlet 112 is located at the bottom of the mounting groove 130.

[0122] The mounting groove 130 is recessed on the side facing the placement surface, which reduces the overall height of the floor brush structure 10 after the dust cup assembly 200 is installed in the mounting groove 130, thereby reducing the volume of the floor brush structure 10. Furthermore, the first air outlet 112 is located at the bottom of the mounting groove 130, which helps to reduce the distance from the first air outlet 112 to the placement surface, and consequently, the distance from the first air inlet 2111 to the placement surface.

[0123] Reference Figure 7 , Figure 12 , Figure 16 As shown, in one possible implementation, the dust cup assembly 200 further includes a locking release member 220 connected to at least one end of the dust cup 210. The mounting groove 130 is provided with a locking part 131, and the locking release member 220 is connected to the locking part 131 to lock the dust cup 210 in the mounting groove 130.

[0124] In this way, when the locking release member 220 is connected to the locking part 131, the dust cup assembly 200 can be locked onto the housing 100 to prevent the dust cup 210 from moving relative to the housing 100, and the first air inlet 2111 and the second air inlet 141 can be directly connected. When the locking release member 220 is disengaged from the locking part 131, the dust cup assembly 200 can be removed from the housing 100 to facilitate cleaning of the dust cup 210.

[0125] Reference Figure 7 , Figure 9 As shown, in some embodiments, the outer side of the dust collection cup 210 also has a first positioning part 212, the locking release member 220 and the first positioning part 212 are located at both ends of the dust collection cup 210, and the mounting groove 130 is also provided with a second positioning part 132, the first positioning part 212 and the second positioning part 132 are connected.

[0126] In other words, one end of the dust collection cup 210 can be positioned by the cooperation of the first positioning part 212 and the second positioning part 132, thereby facilitating the connection between the locking release part 220 and the locking part 131 at the other end of the dust collection cup 210. By cooperating with the first positioning part 212 and the second positioning part 132, one end of the dust collection cup 210 can be connected to the housing 100. By cooperating with the locking release part 220 and the locking part 131, the other end of the dust collection cup 210 can also be connected to the housing 100, thereby effectively restricting the position of the dust collection cup 210, preventing the dust collection cup 210 from rotating relative to the housing 100, and ensuring accurate docking of the first air inlet 2111 and the second air outlet 2112.

[0127] Reference Figure 12 As shown, in some embodiments, the dust cup assembly 200 may further include a cyclone cone 230 and a filter unit 240. The cyclone cone 230 is disposed in the dust collection chamber 211 to separate dust and gas in the fluid entering the dust collection chamber 211. The filter unit 240 is used to filter the fluid discharged from the dust collection chamber 211 to prevent small solid particles from continuing to flow into the host 20.

[0128] In a specific implementation, the dust collection cup 210 may include a first cup body 210a and a second cup body 210b to facilitate opening the dust collection chamber 211 for cleaning the dust collection chamber 211 and the cyclone cone 230 disposed in the dust collection chamber 211. After the first cup body 210a and the second cup body 210b are connected, they can jointly define the dust collection chamber 211. Furthermore, a third sealing member 250 may be provided at the connection between the first cup body 210a and the second cup body 210b to prevent fluid from leaking from the gap between the first cup body 210a and the second cup body 210b.

[0129] The cyclone cone 230 is arranged parallel to the axial direction of the dust collection cup 210, and the axial direction of the cyclone cone 230 is parallel to the placement surface. In this way, the dust cup assembly 200 can be horizontally mounted on the housing 100 to facilitate the connection between the first air inlet 2111 and the first air outlet 112, and to reduce the overall height of the floor brush structure, thereby reducing the volume of the floor brush structure.

[0130] Reference Figures 14 to 16As shown, in some embodiments, the housing 100 also has an air cavity 140, which is configured to be connected to the main unit 20 of the cleaning device. The air cavity 140 has a second air inlet 141, and the dust collection chamber 211 has a second air outlet 2112. The second air outlet 2112 is disposed opposite to and abuts against the second air inlet 141 to connect the dust collection chamber 211 and the air cavity 140.

[0131] Thus, since the second air outlet 2112 is connected to the second air inlet 141, the dust collection chamber 211 can be connected to the air chamber 140, thereby connecting the air duct 110, the dust collection chamber 211, the air chamber 140, and the main unit 20 in sequence. This facilitates the main unit 20 driving the fluid to flow sequentially along the air duct 110, the dust collection chamber 211, the air chamber 140, and the main unit 20. Furthermore, the second air outlet 2112 and the second air inlet 141 can be directly connected, thereby shortening the flow path of the fluid from the dust collection chamber 211 to the air chamber 140.

[0132] Reference Figures 4 to 6 , Figure 13 As shown, in one possible implementation, the floor brush structure 10 further includes a second seal 400, which abuts against the second air inlet 141 and the second air outlet 2112 to seal the gap between the second air inlet 141 and the second air outlet 2112.

[0133] With this configuration, when the dust collection cup 210 is installed into the housing 100 and the second air inlet 141 and the second air outlet 2112 come into contact, the second seal 400 can abut against the gap between the second air inlet 141 and the second air outlet 2112 to seal the gap between the second air inlet 141 and the second air outlet 2112, thereby preventing fluid from leaking from the gap between the second air inlet 141 and the second air outlet 2112, thus improving the suction power of the floor brush structure 10 and improving the dust collection effect of the floor brush structure 10.

[0134] Reference Figures 4 to 6 , Figure 13 As shown, in some embodiments, the housing 100 has a second sealing groove 150, which surrounds the outer periphery of the second air inlet 141, and the second sealing member 400 is disposed in the second sealing groove 150 and abuts against the dust collection cup 210.

[0135] By providing a second sealing groove 150 on the housing 100 and placing the second sealing member 400 in the second sealing groove 150, the second sealing member 400 can be fixed on the housing 100. Furthermore, by placing the second sealing groove 150 on the outer periphery of the second air inlet 141, when the dust collection cup 210 is installed on the housing 100, the second sealing member 400 can accurately abut between the second air inlet 141 and the second air outlet 2112, thereby improving the sealing effect of the second sealing member 400.

[0136] Reference Figures 4 to 6 , Figure 13 and Figure 14 As shown, in some embodiments, the housing 100 includes an upper cover 100a and a bottom cover 100b, which are connected to jointly define an air outlet 140, a second air inlet 141, and a third air outlet 142. An air duct 110 is located on the side of the bottom cover 100b opposite to the upper cover 100a, and a mounting groove 130 is located on the side of the upper cover 100a opposite to the bottom cover 100b. Thus, the upper cover 100a and the bottom cover 100b are respectively machined and then assembled into the housing 100, which facilitates the machining and assembly of the housing 100.

[0137] Reference Figure 4 , Figure 14 As shown, in one possible implementation, the floor brush structure 10 also includes a connecting pipe 500, one end of which is connected to the main unit 20 of the cleaning device, and the other end of which is connected to the air chamber 140.

[0138] This configuration allows the dust collection chamber 211 to be connected to the air chamber 140, thereby connecting the air duct 110, dust collection chamber 211, air chamber 140, connecting pipe 500 and main unit 20 in sequence. This facilitates the main unit 20 in driving the fluid to flow sequentially along the air duct 110, dust collection chamber 211, air chamber 140, connecting pipe 500 and main unit 20.

[0139] The main unit 20 can be detachably connected to the connecting pipe 500 to facilitate the separate storage of the main unit 20 and the floor brush structure 10.

[0140] Reference Figures 4 to 6 , Figure 13 , Figure 14 As shown, in one possible implementation, the floor brush structure 10 further includes a flow guide 600, the air cavity 140 has a third air outlet 142, and the connecting pipe 500 has a third air inlet 510. The third air outlet 142 is connected to the third air inlet 510. The third air inlet 510 is connected to the third air outlet 142 through the flow guide 600, and the flow guide 600 is configured to guide the fluid to flow axially along the third air inlet 510.

[0141] In this way, when the fluid flows from the side of the air cavity 140 away from the third air outlet 142 toward the third air outlet 142, the guide member 600 can guide the fluid to flow axially along the third air inlet 510, thereby preventing the fluid from rotating circumferentially along the third air inlet 510, and thus preventing the formation of a cyclone at the junction of the third air outlet 142 and the third air inlet 510, thereby reducing the energy loss of the floor brush structure 10 and reducing the load on the fan assembly 202, thereby improving the working efficiency and cleaning effect of the cleaning equipment.

[0142] Reference Figure 16 and Figure 17 As shown, in some embodiments, the guide member 600 includes a connecting part 610 and a guide part 620, a third air inlet 510 is connected to the connecting part 610, a third air outlet 142 is connected to the guide part 620, and the guide part 620 is connected to the side of the connecting part 610 facing the air cavity 140.

[0143] Thus, the third air inlet 510 can be connected to the third air outlet 142 through the connecting part 610, thereby allowing the connecting part 610 to act as a joint between the third air inlet 510 and the third air outlet 142. Furthermore, the guide part 620 can guide the fluid to flow along the axial direction of the third air inlet 510, preventing the fluid from generating a cyclone at the junction of the third air inlet 510 and the third air outlet 142, thereby improving the suction of the floor brush structure 10.

[0144] Reference Figures 17 to 20 As shown, in some embodiments, the flow guide 620 includes at least two flow guide ribs 621, each of which extends radially along the third air inlet 510. The at least two flow guide ribs 621 are spaced apart circumferentially along the third air inlet 510, and a flow guide channel 622 is defined between two adjacent flow guide ribs 621.

[0145] In this way, multiple guide ribs 621 can define multiple guide channels 622, and the fluid can be diverted to multiple guide channels 622 and flow along the guide channels 622. The guide channels 622 also extend radially along the third air inlet 510, which can prevent the fluid from rotating around the axial direction of the third air inlet 510 and make the fluid flow radially along the third air inlet 510 and then flow axially along the third air inlet 510. This prevents the fluid from generating a cyclone at the junction of the third air inlet 510 and the third air outlet 142, thereby reducing the suction loss of the floor brush structure 10 and improving the cleaning effect of the floor brush structure 10.

[0146] Reference Figures 17 to 20 As shown, in some embodiments, the connecting part 610 includes a plug tube 611, which is plugged into the third air inlet 510. The plug tube 611 is open at both ends to connect the third air inlet 510 and the third air outlet 142.

[0147] The airflow guide 620 also includes a support plate 623, which is connected to the end of the insertion pipe 611 facing the air cavity 140. The support plate 623 is provided with an avoidance opening, which is opposite to and connected to the end of the insertion pipe 611 facing the air cavity 140. The support plate 623 is snapped into the third air outlet 142, and the airflow guide rib 621 is connected to the side of the support plate 623 facing the air cavity 140.

[0148] In this way, the connector 611 can be inserted into the third air inlet 510, so that the connector 611 connects the housing 100 and the connecting pipe 500, thereby connecting and communicating the third air inlet 510 and the third air outlet 142. Furthermore, by setting the support plate 623 to be snapped into the third air outlet 142, the guide member 600 is connected to the housing 100, so that both the connecting pipe 500 and the housing 100 are connected to the guide member 600.

[0149] In addition, the support plate 623 can be used to support the guide rib 621 to fix the guide rib 621 at the junction of the third air inlet 510 and the third air outlet 142, and make the guide rib 621 located on the outer periphery of the third air inlet 510. Avoiding the gap can prevent the support plate 623 from blocking the third air inlet 510 and the third air outlet 142.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
