Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning component and a cleaning equipment. Background Art

[0002] With the development of technology, cleaning equipment such as sweepers and vacuum cleaners are becoming increasingly widespread. These cleaning equipment is used in a variety of scenarios and on a variety of surfaces, such as floors with flooring, floors without flooring, and carpeted floors. Different cleaning surfaces have varying degrees of dirtiness. Due to this diversity of scenarios, existing cleaning equipment can only meet the cleaning requirements of most dirty areas and cannot effectively clean particularly dirty areas, such as areas deep inside carpets. Utility Model Content

[0003] In view of the above problems existing in the prior art, the present invention provides a cleaning assembly and a cleaning device to improve the problem that the existing cleaning equipment cannot achieve an effective cleaning effect when encountering special dirty areas.

[0004] To achieve the above-mentioned purpose and other related purposes, the first aspect of the present invention provides a cleaning assembly, which includes a shell, a shielding member, and a driving mechanism. A dust suction chamber is formed in the shell, with the forward direction of the cleaning device as the front, and the front wall of the shell is provided with an opening connected to the dust suction chamber, so that there is a gap between the front wall of the shell and the cleaning surface; the shielding member is movably mounted on the shell and has a first position and a second position. When the shielding member is in the first position, it covers part of the opening, so that the ventilation area at the opening is smaller than the ventilation area when the shielding member is in the second position; the driving mechanism drives the shielding member to move between the first position and the second position.

[0005] When the shielding member is in the first position, it covers part of the opening, so that the ventilation area at the opening is smaller than the ventilation area when the shielding member is in the second position. That is, when the shielding member is in the first position, the suction force at the opening is increased, the adsorption capacity of dirt is improved, and the cleaning effect is improved, thereby meeting the cleaning needs of dirt in various scenarios and improving the cleaning effect.

[0006] In an embodiment of the present invention, the shielding member includes a connecting portion and a shielding portion, the shielding portion is made of a flexible material, the connecting portion is connected to the driving mechanism, and the shielding portion is fixed to the connecting portion.

[0007] The shielding element consists of a connecting portion and a shielding element. The connecting portion can be made of a hard material, while the shielding element can be made of a flexible material such as rubber, plastic, or silicone. This effectively ensures that the shielding element covers the opening and allows the shielding element to elastically deform when large particles squeeze the shielding element, allowing large particles to be sucked into the dust collection chamber, thereby improving the cleaning ability. The hard connecting portion facilitates connection to the drive mechanism and provides a certain degree of rigidity to ensure that the shielding element moves along the designed path.

[0008] In one embodiment of the present invention, a mounting groove is provided on a side of the connecting portion close to the shell, and the shielding portion is embedded in the mounting groove so that the side of the connecting portion close to the shell is flush with the side of the shielding portion close to the shell.

[0009] By setting the installation groove, the connecting part close to the shell side is flush with the shielding part close to the shell side, so that the shielding part can move more smoothly when relative to the shell, avoiding the situation where the uneven surface of the shielding part causes interference and affects the movement of the shielding part during the movement.

[0010] In one embodiment of the present invention, a first mounting hole is provided in the mounting groove, and a first mounting portion corresponding to the first mounting hole is provided on the shielding portion and inserted into the first mounting hole so that the shielding portion is fixed to the connecting portion.

[0011] The blocking portion and the connecting portion are fixed to each other by inserting the first mounting portion into the first mounting hole. The connection method is simple, and the convenience of assembling the connecting portion and the blocking portion is improved.

[0012] In one embodiment of the present invention, the shielding member includes a reinforcing portion and a shielding portion. The shielding portion is made of a flexible material. The reinforcing portion is fixed to the shielding portion. The elastic modulus of the reinforcing portion is greater than the elastic modulus of the shielding portion.

[0013] By fixing the reinforcing portion on the shielding member, the strength of the shielding member is improved, thereby reducing the deformation of the shielding member caused by the increase in suction force, and ensuring the shielding effect of the shielding member.

[0014] In an embodiment of the present invention, the reinforcing portion is provided on a side of the shielding portion facing away from the shell, and / or the reinforcing portion is embedded in the shielding portion.

[0015] When the reinforcing portion is arranged on a side of the shielding portion away from the shell, the reinforcing portion can not only enhance the strength of the shielding portion but also protect the shielding portion.

[0016] In an embodiment of the present invention, a second mounting hole is provided on the shielding portion and a second mounting portion is provided on the shielding portion, and the second mounting portion is inserted into the second mounting hole so that the shielding portion and the reinforcing portion are fixed.

[0017] The second mounting portion is inserted into the second mounting hole to secure the shielding portion to the reinforcement portion, facilitating assembly of the shielding portion and the reinforcement portion. The second mounting portion and the second mounting hole form an interference fit, effectively ensuring the connection strength between the shielding portion and the reinforcement portion, and preventing the shielding portion and the reinforcement portion from separating from each other.

[0018] In an embodiment of the present invention, a plurality of groups of the second mounting portions are arranged along the length direction of the shielding portion, and each group of the second mounting portions includes a plurality of the second mounting portions arranged along the height direction of the shielding portion.

[0019] By setting up multiple groups of mounting parts, the connection strength between the shielding part and the mounting part can be improved. At the same time, the shielding part between each group of second mounting parts can also be slightly deformed so that large particles can be squeezed by the shielding part and then adsorbed into the dust collection chamber.

[0020] In one embodiment of the present invention, the reinforcing portion includes a cross bar and a plurality of longitudinal teeth, the length direction of the cross bar is consistent with the length direction of the shielding portion, the longitudinal teeth are fixed on the cross bar, and the plurality of longitudinal teeth are arranged along the length direction of the cross bar.

[0021] The shielding part can elastically deform in the area between the longitudinal teeth, allowing large particles to enter the dust collection chamber through the area between the longitudinal teeth. The elastic deformation of the shielding part occurs between the longitudinal teeth, while the shielding part in other areas ensures that the opening is covered, ensuring strong suction at the opening.

[0022] In one embodiment of the present invention, the cleaning assembly includes a plurality of lifting teeth, which are arranged on the front side of the shell and extend toward the opening, and the shielding member is arranged in front of the lifting teeth.

[0023] When the floor is uneven or has steps, the lifting teeth on the front of the housing first contact the steps, lifting the housing and allowing the cleaning equipment to pass through the steps, improving the cleaning equipment's accessibility. The shielding member is located in front of the lifting teeth, so that the lifting teeth can support the shielding member, reducing deformation caused by strong suction and improving the strength of the shielding member.

[0024] In an embodiment of the present invention, at least part of the longitudinal teeth correspond to the positions of the lifting teeth.

[0025] The lifting teeth support the longitudinal teeth, increasing their load-bearing capacity. When the longitudinal teeth and lifting teeth are aligned, the gaps between the lifting teeth align with the gaps between the longitudinal teeth, ensuring that large particles can enter the dust collection chamber through the gaps between the longitudinal teeth. This also further reduces deformation of other areas of the shield when large particles squeeze the shield into the dust collection chamber.

[0026] In one embodiment of the present invention, the shielding portion is an arc-shaped shielding portion, the cleaning assembly includes at least one roller brush, and the axis of the arc-shaped shielding portion is parallel to the axis of the roller brush.

[0027] The arc-shaped shielding portion can not only ensure the covering of the opening, but also facilitate the movement of the shielding member along the surface of the shell, thereby saving space for the movement of the shielding member and facilitating the design and utilization of the internal space of the cleaning device.

[0028] In an embodiment of the present invention, the shielding member slides along the surface of the housing to move between the first position and the second position.

[0029] When the shielding member slides along the surface of the shell, the shielding member adapts to the surface of the shell, so that the space occupied by the shielding member during movement is small, thereby facilitating the design and utilization of the internal space of the cleaning device.

[0030] In an embodiment of the present invention, the cleaning assembly includes a first cover plate, which is disposed on the front side of the shell. A gap for accommodating the movement of the shielding member is formed between the first cover plate and the shell.

[0031] The gap formed between the first cover plate and the shell serves to limit the shielding member. The movement of the shielding member along the gap can ensure that the moving trajectory of the shielding member is the set trajectory, thereby avoiding interference with other components in the cleaning equipment during the movement of the shielding member and improving the design and utilization of the internal space of the cleaning equipment.

[0032] In one embodiment of the present invention, the side of the shell facing away from the dust suction chamber serves as the top surface, and the driving mechanism is arranged on the top surface of the shell.

[0033] The space on the top surface of the shell is used to set the driving mechanism, thereby improving the compactness of the internal structure of the cleaning equipment and facilitating the internal design and utilization of the cleaning equipment.

[0034] In an embodiment of the present invention, the driving mechanism includes a driving portion and a transmission mechanism, and the transmission mechanism is connected to the shielding member to drive the shielding member to move between the first position and the second position.

[0035] The transmission mechanism rotates with the shielding member, so that the transmission mechanism can drive the shielding member to move when it rotates, thereby facilitating planning of the moving path of the shielding member and allowing the shielding member to move along a predetermined gap.

[0036] In one embodiment of the present invention, the transmission mechanism includes a first connecting rod and a second connecting rod fixed to the output shaft of the driving part, the second connecting rod is rotatably connected to the first connecting rod, and the second connecting rod is rotatably connected to the shielding member.

[0037] The transmission is carried out through the connecting rod mechanism, which converts the rotation of the driving part into the movement of the shielding member, effectively driving the shielding member to move along the preset path.

[0038] In one embodiment of the present invention, the first connecting rod is a cylindrical connecting rod, the axis of the cylindrical connecting rod coincides with the output shaft of the driving part, the second connecting rod is connected to the end face of the cylindrical connecting rod away from the driving part, and the connection point between the second connecting rod and the cylindrical connecting rod deviates from the axis of the cylindrical connecting rod.

[0039] The cylindrical connecting rod structure is the same as the eccentric wheel structure. Compared with the slender connecting rod, the cylindrical connecting rod can play the role of a counterweight, so that the movement of the first connecting rod driven by the driving part is more stable.

[0040] In one embodiment of the present invention, the driving mechanism includes a stopping structure, and the stopping structure includes a sensing portion and a sensed portion. When the sensing portion senses the sensed portion, the driving portion stops.

[0041] By means of the sensing part and the sensed part, the driving part drives the shielding member to move to a predetermined position and stops, thereby causing the shielding member to stay in the first position and the second position. Furthermore, multiple sensed parts can be provided so that the shielding member can stay in other positions between the first position and the second position, so that the suction force at the opening can be adjusted according to actual needs, meeting the needs of various scenarios.

[0042] In one embodiment of the present invention, the cleaning assembly includes a scraper disposed on the rear side of the housing, and the scraper has a lowered third position and a raised fourth position.

[0043] The scraper can intercept the dirt at the bottom of the shell, thereby preventing the dirt from escaping from the shell and causing secondary pollution.

[0044] In one embodiment of the present invention, the driving mechanism drives the scraper to move between the third position and the fourth position; the shielding member moves synchronously with the scraper in opposite directions, and when the shielding member moves to the first position, the scraper moves to the fourth position, and when the shielding member moves to the second position, the scraper moves to the third position.

[0045] When the cleaning surface is a carpet, in order to absorb dirt deep in the carpet, the shielding member moves to the first position, and the scraper moves to the raised fourth position, that is, a higher position, to meet the cleaning needs of the carpet.

[0046] In one embodiment of the present utility model, the transmission mechanism includes a first connecting rod, a second connecting rod, a third connecting rod and a fourth connecting rod, the first connecting rod and the fourth connecting rod are fixedly connected to the output shaft of the driving part, the second connecting rod is rotatably connected to the first connecting rod, and the shielding member is rotatably connected to the second connecting rod; the third connecting rod rotates synchronously with the output shaft of the driving part, the fourth connecting rod is rotatably connected to the third connecting rod, and the scraper is rotatably connected to the fourth connecting rod.

[0047] The driving unit drives the shielding member and the scraper simultaneously through one transmission mechanism, which reduces the number of driving mechanisms, reduces costs, and improves the synchronization of the movement of the shielding member and the scraper.

[0048] In one embodiment of the present invention, the third connecting rod and the first connecting rod are fixed via a synchronization rod, and the second connecting rod is rotationally connected to the synchronization rod so that the second connecting rod rotates with the first connecting rod.

[0049] The synchronization rod serves as both a connecting rod for the third link and the first link and a rotation axis for the second link, making the design of the transmission mechanism more compact, reducing space occupation, and facilitating the design and utilization of the internal space of the cleaning equipment.

[0050] In an embodiment of the present invention, when the cleaning surface is a carpet, the shielding member is located at the first position.

[0051] Dirt is more likely to be hidden in the carpet, such as hair, debris, etc., which will sink deep into the carpet. By moving the shielding member to the first position, the cleaning effect of the carpet can be improved to meet the cleaning needs of the carpet.

[0052] In an embodiment of the present invention, a dust suction duct is provided on the shell, and the opening is communicated with the dust suction duct.

[0053] The dust collection duct is connected to the dust box of the cleaning equipment, so that the dirt is adsorbed into the dust box for collection, reducing the dirt contained in the dust collection chamber and reducing the risk of secondary pollution.

[0054] A second aspect of the present invention provides a cleaning device, comprising a device body and any one of the above-mentioned cleaning components, wherein the cleaning component is installed on the device body.

[0055] The shielding member of the cleaning component has a first position and a second position, which can change the air inlet area of ​​the opening, thereby adjusting the suction force of the opening. For example, when it is a carpet, the shielding member is in the first position to increase the suction force of the opening. When it is a floor, the shielding member is in the second position to ensure that large particles can enter the dust collection chamber more quickly, thereby meeting the dirt cleaning needs in different scenarios.

[0056] The third aspect of the present utility model provides a cleaning device, comprising a device main body and a cleaning component installed on the device main body, the cleaning component comprising a shell, a dust suction chamber formed in the shell, and a front wall of the shell being provided with an opening connected to the dust suction chamber with the forward direction of the cleaning device as the front, so that there is a gap between the front wall of the shell and the cleaning surface; a shielding member, movably installed on the device main body, and having a first position and a second position, wherein the ventilation area at the opening of the covering part when the shielding member is in the first position is smaller than the ventilation area when the shielding member is in the second position; a driving mechanism drives the shielding member to move between the first position and the second position.

[0057] In an embodiment of the present invention, the shielding member is rotatably connected to the device body.

[0058] In combination with the existing technology, the beneficial effects of the present invention are:

[0059] Existing cleaning equipment cannot meet the needs of cleaning dirt in different scenarios when working, and cannot achieve effective cleaning results. The cleaning component of the present application is provided with a shielding member, which can move between a first position and a second position as needed. When encountering ordinary dirt, the shielding member is in the second position, which can meet the use needs of dirt in most scenarios; when encountering special dirt, such as dirt located in the carpet, the shielding member moves to the second position, and covers part of the opening area through the shielding plate. Compared with the second position, the ventilation area of ​​the opening in the first position is smaller. By reducing the area of ​​the opening for air intake, the suction force of the opening is increased, the adsorption capacity of dirt is improved, and the cleaning effect is improved, meeting the cleaning needs of dirt in various scenarios and improving the cleaning effect.

[0084] The following describes the implementation of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementation methods. The details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following examples and the features in the examples can be combined with each other unless there is a conflict. It should also be understood that the terms used in the examples of the present invention are for the purpose of describing specific implementation methods, not for the purpose of limiting the scope of protection of the present invention. The test methods for which specific conditions are not specified in the following examples are generally carried out under conventional conditions or under the conditions recommended by the manufacturers.

[0085] When numerical ranges are given in the examples, it should be understood that unless otherwise specified herein, both endpoints of each numerical range and any value between the endpoints may be used. Unless otherwise defined, all technical and scientific terms used in this utility model are consistent with the prior art as understood by those skilled in the art and the description of this utility model. Any prior art methods, equipment, and materials similar or equivalent to those in the examples of this utility model may also be used to implement this utility model.

[0086] It should be noted that the terms such as "upper", "lower", "left", "right", "middle" and "one" cited in this specification are only for the convenience of description and are not used to limit the scope of implementation of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content.

[0087] The cleaning component of the cleaning equipment may include a negative pressure mechanism, which includes a dust suction chamber and a negative pressure fan. The dust suction chamber is connected to the cleaning surface and the negative pressure fan. The negative pressure fan is used to apply negative pressure to the dust suction chamber to suck out dust, particles and other dirt on the cleaning surface. Figure 2 As shown, the negative pressure mechanism may include a shell 100, which may be formed with a dust suction chamber. A suction port 140 is provided at one end of the shell 100 facing the cleaning surface, and a dust outlet (not shown) connected to a dust suction duct 130 is provided at the other end. The dust suction duct 130 may be connected to a dust inlet (not shown) of a dust box, and the dust suction duct of the dust box may be connected to a negative pressure fan (not shown). The negative pressure fan may generate negative pressure in the dust suction chamber to suck dust, large particles (such as cat litter) and other dirt on the cleaning surface, so that the airflow carrying dirt passes through the suction port 140 and the dust outlet of the shell 100, the dust suction duct 130, the dust box, and the negative pressure fan, and is discharged through the outlet of the negative pressure fan, and the dirt is left in the dust box.

[0088] The cleaning component of the cleaning device may also include a roller brush mechanism, which may include a roller brush drive and a roller brush 400, wherein the roller brush 400 may be arranged in the dust suction chamber, and the roller brush drive may be arranged on the surface of the shell 100 away from the dust suction chamber. The roller brush drive may drive the roller brush 400 to rotate, so as to further drive the dirt on the cleaning surface to move in the dust suction chamber, and then further use the negative pressure to suck the dirt into the dust box, thereby improving the cleaning effect of the cleaning component on dust, particulate matter and other dirt on the cleaning surface.

[0089] When the cleaning device is working, in order to ensure the negative pressure value in the dust collection chamber and the roller brush drives the dirt on the cleaning surface, the bottom of the shell 100 is usually in direct contact with the cleaning surface or the gap from the cleaning surface is very small. If a roller brush 400 is provided, the roller brush usually also needs to be in contact with the cleaning surface to drive the dirt on the cleaning surface to move. However, the cleaning device usually needs to perform cleaning on different types of cleaning surfaces, such as floors, carpets, etc. The dirt on the floor is usually attached to the floor. If the bottom of the shell 100 is in contact with the cleaning surface, although the negative pressure value of the dust collection chamber can be guaranteed to be large, the large particles on the floor will usually be pushed by the shell 100 and cannot enter the dust collection chamber, making it difficult to clean the large particles on the floor. If the cleaning surface is a carpet, more dirt is hidden deep in the carpet, and a larger negative pressure value is required to clean it.

[0090] In the embodiment of this specification, with the forward direction of the cleaning device as the front, an opening 110 communicating with the dust collection chamber is provided on the front wall of the housing 100. This creates a gap between the front wall of the housing 100 and the cleaning surface. As the cleaning device advances, large particles can enter the dust collection chamber through the opening 110, improving the cleaning effect on large particles on the floor. A shielding member 200 can also be provided to partially block the opening 110, thereby changing the ventilation area of ​​the opening 110.

[0091] For example, when cleaning a carpet, the shielding member 200 can block the opening 110 to increase the negative pressure within the dust collection chamber, thereby sucking out dirt, dust particles, and other contaminants hidden deep within the carpet. The shielding member 200 can block the portion of the opening 110 where the shielding member completely blocks the opening 110, preventing airflow from entering the dust collection chamber through the opening 110. Alternatively, the shielding member 200 can partially block the opening 110, allowing airflow to still pass through the opening 110. When the shielding member 200 does not completely block the opening, the ventilated portion of the opening can be located above and / or below the shielding member 200. For a long-haired carpet, the opening can be located within the carpet, with the ventilated portion of the opening located above the shielding member 200, allowing dirt floating on the carpet to enter the dust collection chamber through the ventilated portion of the opening 110. If the ventilated portion of the opening 110 is located below the shielding member 200, allowing dirt from the lower portion of the carpet to enter the dust collection chamber through the ventilated portion of the opening 110.

[0092] When on the floor, the shielding member 200 may not block the opening 110 to ensure that large particles can smoothly enter the suction chamber. Alternatively, on the floor, while ensuring that there is a gap between the front wall of the housing 100 and the floor, the shielding member may be used to block the opening 110 as needed. For example, when no large particles are detected, the shielding member may be controlled to increase the blocking area of ​​the opening 110 to reduce the ventilation area of ​​the opening 110. When a large amount of large particles such as cat litter are detected, the shielding member may be controlled to reduce the blocking area of ​​the opening 110 to increase the ventilation area of ​​the opening 110, thereby ensuring the particle cleaning effect in special scenarios.

[0093] When the shielding member 200 covers the opening 110 , it may be disposed on a side of the housing 100 facing away from the dust collection chamber to prevent the shielding member 200 from interfering with the roller brush 400 during movement.

[0094] See also Figures 1 to 9The first aspect of the present invention provides a cleaning assembly, comprising a shell 100, a shielding member 200 and a driving mechanism 300. A dust suction chamber is formed in the shell 100. With the forward direction of the cleaning device as the front, the front wall of the shell 100 is provided with an opening 110 connected to the dust suction chamber, so that there is a gap between the front wall of the shell 100 and the cleaning surface, thereby facilitating the forward movement of the cleaning device. Dirt on the moving path of the cleaning device enters the dust suction chamber through the opening 110; by providing the opening 110, the gap between the front wall of the shell 100 and the cleaning surface is increased, thereby making it easier for large particles of dirt to be sucked into the dust suction chamber. A suction port 140 is provided at the bottom of the dust suction chamber, and the front side of the suction port 140 is an opening 110 that passes through the front wall of the shell 100. Dirt enters the dust suction chamber through the opening 110 or other areas of the suction port 140, and is then transported to the dust box of the cleaning device under the drive of the airflow. The shielding member 200 is movably mounted on the housing 100 and has a first position and a second position. When the shielding member 200 is in the first position, it partially covers the opening 110, so that the ventilation area at the opening 110 is smaller than the ventilation area when the shielding member 200 is in the second position. This increases the suction force at the opening 110 when the shielding member 200 is in the first position, improving the adsorption capacity of dirt and enhancing the cleaning effect, thereby meeting the cleaning needs of dirt in various scenarios and improving the cleaning effect. The driving mechanism 300 drives the shielding member 200 to move between the first position and the second position.

[0095] In one embodiment, when the cleaning surface is a carpet, the shielding member 200 is in the first position. Carpets are more likely to harbor dirt, such as hair and debris, which tend to sink deeper into the carpet. By moving the shielding member 200 to the first position, the carpet cleaning effect can be improved, meeting the cleaning requirements. When the cleaning surface is a floor, the shielding member 200 is in the second position to ensure the suction of large particles.

[0096] In one embodiment, the shielding member 200 covers the upper side of the opening 110, ensuring that a gap exists between the front wall of the housing 100 and the cleaning surface when the opening 110 is not fully covered. When cleaning a carpet, the housing 100 contacts the carpet surface, and the cleaning device is supported by the material on the carpet. However, there is a certain distance between the cleaning device and the gaps deep in the carpet. By covering the upper side of the opening 110, the suction force at the opening 110 is effectively increased, and the center of the airflow flowing through the opening 110 is lowered, thereby adjusting the relative position of the airflow and the deep part of the carpet, making it easier for the airflow to flow through the deep part of the carpet. By increasing the suction force and adjusting the airflow direction, the cleaning ability of dirt deep in the carpet is effectively enhanced, improving the cleaning effect. In one embodiment, the shielding member 200 extends to both ends of the opening 110 in the length direction, thereby improving the shielding effect of the shielding member 200 on the opening 110, reducing the airflow entering the dust suction chamber from both sides of the opening 110, and most of the airflow enters the dust suction chamber through the lower side of the opening 110, thereby improving the adsorption effect of dirt on the cleaning surface.

[0097] In one embodiment, in order to increase the suction force of the opening 110, ensure the cleaning ability of dirt, and at the same time facilitate some large particles to enter the dust suction chamber through the opening 110, the covering area of ​​the shielding member 200 can be made of flexible materials, such as rubber, silicone, plastic, etc., so that large particles can squeeze the shielding member 200 into the dust suction chamber.

[0098] See also Figure 8 and Figure 9 In one embodiment, the shielding member 200 includes a connecting portion 210 and a shielding portion 220. The connecting portion 210 is connected to the driving mechanism 300, and the shielding portion 220 is fixed to the connecting portion 210. The connecting portion 210 is preferably made of a hard material, such as hard plastic, to ensure the connection strength between the connecting portion 210 and the driving mechanism 300 and prevent the shielding member 200 from being separated from the driving mechanism 300. The hard material connecting portion provides the shielding member 200 with a certain degree of rigidity, ensuring that the shielding member 200 moves along the designed route and reducing wrinkles and jams caused by friction, interference, etc. during movement of the shielding member 200. The shielding portion 220 is preferably made of a flexible material, such as rubber, plastic, silicone, etc., which not only effectively ensures that the shielding portion 220 covers the opening 110, but also allows the shielding portion 220 to undergo elastic deformation when some large particles squeeze the shielding portion 220, thereby allowing the large particles to be adsorbed into the dust collection chamber, thereby improving the cleaning ability of dirt.

[0099] See also Figure 8 and Figure 9In one embodiment, a mounting groove 211 is provided on the side of the connecting portion 210 near the housing 100, and the shielding portion 220 is embedded in the mounting groove 211, so that the side of the connecting portion 210 near the housing 100 is flush with the side of the shielding portion 220 near the housing 100. By providing the mounting groove 211, the side of the connecting portion 210 near the housing 100 and the side of the shielding portion 220 near the housing 100 are flush, thereby making the shielding member 200 smoother when moving relative to the housing 100, and preventing the shielding member 200 from interfering with or affecting its movement due to uneven surfaces. It should be noted that the connection part 210 close to the shell 100 and the shielding part 220 close to the shell 100 can be flush with each other on a flat surface or on a curved surface. For example, when the shielding part 220 is an arc-shaped shielding part 220, there is a smooth transition between the arc-shaped shielding part 220 and the connection part 210.

[0100] In another embodiment, a mounting groove 211 is provided at the bottom of the connecting portion 210, that is, a mounting groove 211 is provided at one end of the connecting portion 210 close to the shielding portion 220, and an insertion portion is provided at the end of the shielding portion 220, and the insertion portion matches the mounting groove 211, so that when the insertion portion is inserted into the mounting groove 211, the shielding portion 220 is fixed to the connecting portion 210.

[0101] In other embodiments, the shielding portion 220 and the connecting portion 210 may also be connected by existing fixing methods such as gluing, rivet connection, etc., which will not be elaborated in this application.

[0102] In another embodiment, a mounting groove 211 is provided on the side of the connecting portion 210 facing away from the housing 100, and the shielding portion 220 is embedded in the mounting groove 211, thereby fixing the shielding portion 220 to the mounting groove 211. When the cleaning device is in operation, air flows from the outside of the opening 110 to the inside of the opening 110, causing the shielding portion 220 to move from the outside of the opening 110 to the inside of the opening 110. By providing the mounting groove 211 on the side facing away from the housing 100, the connecting portion 210 can support the shielding portion 220, thereby improving the connection strength between the shielding portion 220 and the connecting portion 210.

[0103] See also Figure 7 and Figure 8In one embodiment, a first mounting hole 212 is provided in the mounting groove 211, and a first mounting portion 221 corresponding to the first mounting hole 212 is provided on the shielding portion 220. The first mounting portion 221 is inserted into the first mounting hole 212 so that the shielding portion 220 is fixed to the connecting portion 210. The connection method is simple, which improves the convenience of assembling the connecting portion 210 and the shielding portion 220. Preferably, the first mounting portion 221 is interference fit with the first mounting hole 212. The shielding portion 220 is preferably made of a flexible material. The first mounting portion 221 is inserted into the first mounting hole 212 after being squeezed, so that the first mounting portion 221 and the first mounting hole 212 can be relatively fixed. At the same time, due to the elasticity of the first mounting portion 221, the wall of the first mounting hole 212 is squeezed, thereby improving the connection strength between the first mounting portion 221 and the first mounting hole 212, thereby improving the fixing strength of the shielding portion 220 and the connecting portion 210.

[0104] In another embodiment, a first protrusion is provided in the mounting groove 211, and a first recessed hole is provided on the shielding portion 220. The first protrusion is inserted into the first recessed hole to achieve relative fixation between the shielding portion 220 and the connecting portion 210. Preferably, the first recessed hole is a through hole, and a nail head is provided at the end of the first protrusion. The cross-sectional area of ​​the nail head is larger than the cross-sectional area of ​​the first recessed hole. Therefore, after the first protrusion passes through the first recessed hole, the nail head presses against the shielding portion 220 around the first recessed hole, preventing the first protrusion from separating from the first recessed hole, thereby improving the connection strength between the shielding portion 220 and the connecting portion 210.

[0105] See also Figure 7 and Figure 8 In one embodiment, the shielding portion 220 is made of a flexible material, and the shielding member 200 includes a reinforcing portion 230 fixed to the shielding portion 220. The reinforcing portion 230 has a greater elastic modulus than the shielding portion 220, and its rigidity is greater than that of the shielding portion 220. The reinforcing portion 230 can improve the strength of the shielding portion 220, thereby reducing deformation of the shielding member 200 caused by increased suction or when the cleaning device moves backward, thereby ensuring the shielding effect of the shielding portion 220. The reinforcing portion 230 is made of a hard material, such as hard plastic or hard rubber, to enhance the reinforcing effect of the reinforcing portion 230 on the strength of the shielding portion 220.

[0106] See also Figure 7 and Figure 8In one embodiment, the reinforcing portion 230 is disposed on the side of the shielding portion 220 facing away from the housing 100. When the shielding portion 220 is inserted into the mounting groove 211 on the side of the connecting portion 210 near the housing 100, the side of the shielding portion 220 near the housing 100 is flush with the side of the connecting portion 210 near the housing 100, while the side of the shielding portion 220 facing away from the housing 100 is not flush with the side of the connecting portion 210 facing away from the housing 100. By arranging the reinforcing portion 230 on the side of the shielding portion 220 facing away from the housing 100, the side of the shielding member 200 near the housing 100 is ensured to be flush, reducing the possibility of movement jamming caused by uneven surfaces of the shielding member 200. At the same time, the space on the side of the shielding portion 220 facing away from the housing 100 is utilized, reducing the degree of unevenness on the side of the shielding member 200 facing away from the housing 100, thereby reducing the possibility of jamming.

[0107] In one embodiment, the surface of the connecting portion 210 facing away from the shell 100 is flush with the surface of the reinforcing portion 230 facing away from the shell 100, thereby reducing the unevenness of the surface of the shielding member 200 facing away from the shell 100 and improving the smoothness of the movement of the shielding member 200.

[0108] In one embodiment, there is a gap between the reinforcing portion 230 and the connecting portion 210, and the shielding portion 220 is made of a flexible material. When the movement of the shielding member 200 encounters interference or large friction, the shielding portion 220 between the reinforcing portion 230 and the connecting portion 210 can be deformed, thereby improving the passability of the shielding member 200, facilitating the smooth movement of the shielding member 200, and reducing the occurrence of the shielding member 200 getting stuck.

[0109] In another embodiment, the reinforcing portion 230 is embedded in the shielding portion 220. Preferably, the shielding portion 220 is flush with the side of the connecting portion 210 facing away from the shell 100. By embedding the reinforcing portion 230 into the shielding portion 220, the side of the shielding member 200 facing away from the shell 100 is in a flush state, thereby improving the convenience of moving the shielding member 200.

[0110] In another embodiment, a groove is provided on a side of the shielding portion 220 facing away from the housing 100 , and the reinforcing portion 230 is embedded in the groove to enhance the connection stability between the reinforcing portion 230 and the shielding portion 220 .

[0111] See also Figure 8In one embodiment, the shielding portion 220 is provided with a second mounting hole 231 and a second mounting portion 222. The second mounting portion 222 is inserted into the second mounting hole 231 to fix the shielding portion 220 to the reinforcing portion 230. The second mounting portion 222 and the second mounting hole 231 are conveniently installed, thereby facilitating the assembly of the shielding portion 220 and the reinforcing portion 230. Preferably, the second mounting portion 222 and the second mounting hole 231 have an interference fit. The shielding portion 220 is made of a flexible material. By squeezing the second mounting portion 222 and then inserting it into the second mounting hole 231, the connection strength between the shielding portion 220 and the reinforcing portion 230 is effectively ensured, and the shielding portion 220 and the reinforcing portion 230 are prevented from separating from each other.

[0112] In one embodiment, multiple groups of second mounting portions 222 are arranged along the length of the shielding portion 220, with each group of second mounting portions 222 comprising multiple second mounting portions 222 arranged along the height of the shielding portion 220. Providing multiple groups of mounting portions improves the connection strength between the shielding portion 220 and the mounting portion. Furthermore, the multiple groups of second mounting portions 222 are spaced apart, allowing for slight deformation of the shielding portion 220 between the multiple groups of second mounting portions 222, allowing large particles to squeeze through the shielding portion 220 and be sucked into the dust collection chamber.

[0113] In another embodiment, a second protrusion is provided on the reinforcing portion 230, and a second recess is provided on the shielding portion 220. The second protrusion is inserted into the second recess to achieve relative fixation between the reinforcing portion 230 and the shielding portion 220. Preferably, the reinforcing portion 230 and the shielding portion 220 are fixed by the second mounting hole 231 and the second mounting portion 222. This can reduce damage to the shielding portion 220, thereby improving the integrity of the shielding portion 220 and reducing the probability of damage to the shielding portion 220.

[0114] See also Figure 7 and Figure 8In one embodiment, the reinforcing portion 230 includes a crossbar 232 and a plurality of longitudinal teeth 233, the length direction of which is consistent with the length direction of the shielding portion 220. The longitudinal teeth 233 are fixed to the crossbar 232, and the plurality of longitudinal teeth 233 are arranged along the length direction of the crossbar 232. Preferably, the crossbar 232 is provided in an upper area of ​​the side of the shielding portion 220, and the longitudinal teeth 233 extend downward from the crossbar 232, that is, the longitudinal teeth 233 extend toward the ground, and the shielding portion 220 covers the upper side of the opening 110. The shielding portion 220 can undergo elastic deformation in the area between the longitudinal teeth 233, thereby allowing large particles to enter the dust collection chamber through the area between the longitudinal teeth 233. Large particles enter the dust suction chamber through the area below the opening 110, and the cross bar 232 is set in the area above the shielding part 220, which can ensure the integrity of the reinforcing part 230 and enhance the strength of the shielding part 220. It does not affect the entry of large particles into the dust suction chamber, but also reduces the deformation of other areas of the shielding part 220, thereby ensuring the suction force of the opening 110.

[0115] In one embodiment, the second mounting hole 231 is arranged at the longitudinal teeth 233, so that the reinforcing portion 230 and the shielding portion 220 are stably connected, and the deformation of the shielding portion 220 between other longitudinal teeth 233 when the shielding portion 220 between the longitudinal teeth 233 is reduced. Large particles can enter the dust collection chamber, while ensuring the enhanced effect of suction at the opening 110.

[0116] See also Figure 2 and Figure 5 In one embodiment, the cleaning assembly includes a plurality of lifting teeth 120, which are arranged on the front side of the shell 100 and extend toward the opening 110. When encountering steps or uneven ground, the lifting teeth 120 on the front side of the shell 100 first contact the steps, and then lift the shell 100, so that the cleaning equipment can pass through the steps, thereby improving the passability of the cleaning equipment. Furthermore, the front side of the lifting teeth 120 is an arc-shaped surface, and the arc-shaped surface is inclined from top to bottom into the dust suction chamber, thereby providing guidance when the lifting teeth 120 pass through steps or uneven ground, facilitating the lifting of the shell 100. The arc-shaped surface can also decompose the impact force on the lifting teeth 120 and reduce the risk of damage. The shielding member 200 is disposed in front of the lifting teeth 120. This allows the lifting teeth 120 to support the shielding member 200, reducing deformation of the shielding member 200 due to high suction force and increasing the strength of the shielding member 200. When the shielding portion 220 encounters large particles or steps, it encounters significant resistance. The lifting teeth 120 provide support for the shielding portion 220, preventing the shielding portion 220 from deforming into the dust collection chamber and separating from the connecting portion 210.

[0117] See also Figure 4In one embodiment, at least part of the longitudinal teeth 233 corresponds to the position of the lifting teeth 120. Preferably, the longitudinal teeth 233 correspond to the positions of the lifting teeth 120 one by one, and the longitudinal teeth 233 on both sides correspond to the housing 100. The lifting teeth 120 support the longitudinal teeth 233 to improve the bearing capacity of the longitudinal teeth 233. At the same time, when the longitudinal teeth 233 correspond to the positions of the lifting teeth 120, the gaps between the lifting teeth 120 correspond to the gaps between the longitudinal teeth 233, thereby ensuring that large particles can enter the dust collection chamber through the gaps between the longitudinal teeth 233, and further reducing the deformation of other areas of the shielding portion 220 when large particles squeeze the shielding portion 220 to enter the dust collection chamber. When the connection position between the shielding part 220 and the reinforcing part 230 is located at the longitudinal teeth 233, when the shielding part 220 is subjected to greater resistance, the lifting teeth 120 can also support the connection position between the shielding part 220 and the reinforcing part 230 to prevent the connection position between the shielding part 220 and the reinforcing part 230 from being detached, thereby improving the connection strength between the shielding part 220 and the reinforcing part 230.

[0118] In one embodiment, the surface shape of the portion of the shielding member 200 that covers the opening 110 is adapted to the surface shapes of the housing 100 on either side of the opening 110 in the longitudinal direction, thereby ensuring that the shielding member 200 seals the opening 110. Furthermore, the portion of the front wall of the housing 100 that is adjacent to the cleaning surface is typically curved to ensure that the cleaning assembly can pass through uneven surfaces as the cleaning device moves. Adapting the surface shape of the portion of the shielding member 200 that covers the opening 110 to the surface shapes of the housing on either side of the opening 110 in the longitudinal direction prevents the shielding member 200 from interfering with the movement of the cleaning device, thereby achieving a sealing effect while ensuring that the cleaning assembly can pass through uneven surfaces.

[0119] like Figure 4 As shown, the surface shapes of the shielding portion 220 and the longitudinal teeth 233 of the reinforcing portion 230 are adapted to the surface shapes of the lifting teeth 120 and the surface shapes of the housing 100 on both sides of the opening 110. The shielding portion 220 is an arc-shaped shielding portion 220. The arc-shaped shielding portion 220 not only ensures that the opening 110 is covered, but also facilitates the movement of the shielding member 200 along the surface of the housing 100, thereby saving space for the shielding member 200 to move and facilitating the design and utilization of the internal space of the cleaning device.

[0120] In one embodiment, the axis of the arc-shaped shielding portion 220 is parallel to the axis of the roller brush 400 to further avoid interference between the shielding portion 220 and the roller brush 400 .

[0121] In one embodiment, the connecting portion 210 is an arc-shaped connecting portion 210 , which facilitates the movement of the connecting portion 210 in the cleaning device, saves the internal space of the cleaning device, and facilitates the design and utilization of the internal space.

[0122] In one embodiment, the shielding member 200 slides along the surface of the housing 100 to move between the first position and the second position. The shielding member 200 conforms to the surface of the housing 100, thereby reducing the space occupied by the shielding member 200 during movement, thereby facilitating the design and utilization of the internal space of the cleaning device.

[0123] See also Figure 2 In one embodiment, the cleaning assembly includes a first cover plate 500, which is disposed on the front side of the housing 100. A gap is formed between the first cover plate 500 and the housing 100 to accommodate the movement of the shielding member 200. The gap formed between the first cover plate 500 and the housing 100 serves to limit the shielding member 200. The movement of the shielding member 200 along the gap can ensure that the movement trajectory of the shielding member 200 is the set trajectory, thereby avoiding interference with other components in the cleaning device during the movement of the shielding member 200 and improving the design and utilization of the internal space of the cleaning device. The first cover plate 500 is made of a hard material, preferably a hard plastic, to ensure the limiting effect of the first cover plate 500 and the shielding member 200, while achieving a lightweight design of the cleaning assembly.

[0124] See also Figure 1 and Figure 6 In one embodiment, the side of the housing 100 facing away from the dust collection chamber serves as the top surface, and the drive mechanism 300 is disposed on the top surface of the housing 100. Utilizing the space on the top surface of the housing 100 to dispose the drive mechanism 300 improves the compactness of the internal structure of the cleaning device and facilitates the internal design and utilization of the cleaning device.

[0125] like Figure 4 As shown, the surface shape of the cover plate 500 is adapted to the surface shape of the shielding member 200, and the surface shape of the shielding member 200 is adapted to the top surface of the shell 100. The shielding member 200 is arranged above the top surface, and the driving mechanism 300 can be used to drive the shielding member 200 to slide along the surface of the shell 100.

[0126] See also Figure 4 and Figure 6In one embodiment, the driving mechanism 300 includes a driving portion 310 and a transmission mechanism 320. The transmission mechanism 320 is connected to the shielding member 200 to drive the shielding member 200 to move between the first position and the second position. Preferably, the transmission mechanism 320 drives the shielding member 200 to move along the gap between the housing 100 and the first cover plate 500. Furthermore, the transmission mechanism 320 rotates with the shielding member 200, so that the transmission mechanism 320 can drive the shielding member 200 to move when it rotates, thereby facilitating the planning of the movement path of the shielding member 200 and allowing the shielding member 200 to move along a predetermined gap. The shielding member 200 can share the driving portion 310 of the roller brush 400, or a separate driving portion 310 can be provided. Preferably, the shielding member 200 is provided with a separate driving portion 310 to facilitate independent control of the movement of the shielding member 200.

[0127] In one embodiment, the driving unit 310 includes a motor and a gearbox, and the gearbox is connected to the transmission mechanism 320 , so that the motor drives the transmission mechanism 320 to move, thereby driving the shielding member 200 to move.

[0128] In another embodiment, the driving mechanism 300 may only include a driving portion 310 , such as a telescopic cylinder, which drives the shielding member 200 to move; for example, a motor directly drives the shielding member 200 to rotate.

[0129] See also Figure 6 and Figure 7 In one embodiment, the transmission mechanism 320 includes a first connecting rod 321 and a second connecting rod 322 fixed to the output shaft of the driving unit 310. The second connecting rod 322 is rotationally connected to the first connecting rod 321, and the second connecting rod 322 is rotationally connected to the shielding member 200. The linkage mechanism composed of the first connecting rod 321 and the second connecting rod 322 converts the rotation input by the driving unit 310 into movement of the shielding member 200, effectively driving the shielding member 200 to move along a predetermined path.

[0130] See also Figure 7 In one embodiment, the first connecting rod 321 is a cylindrical connecting rod, the axis of the cylindrical connecting rod coincides with the output axis of the driving portion 310, and the second connecting rod 322 is connected to the end face of the cylindrical connecting rod away from the driving portion 310. The connection between the second connecting rod 322 and the end face of the cylindrical connecting rod does not coincide with the axis of the cylindrical connecting rod. Compared with the slender connecting rod, the cylindrical connecting rod can play the role of a counterweight, so that the movement of the first connecting rod 321 driven by the driving portion 310 is more stable.

[0131] See also Figure 6 and Figure 7In one embodiment, the transmission mechanism 320 also includes a third connecting rod 323, which is a cylindrical connecting rod, and the third connecting rod 323 is fixed to the first connecting rod 321, and the second connecting rod 322 is arranged between the third connecting rod 323 and the first connecting rod 321. Through the two fixed cylindrical connecting rods, the transmission is smoother and the movement of the shielding member 200 is more stable.

[0132] The driving unit 310 can be a separate driving motor that drives the shielding member and / or scraper bar to move, or it can reuse other driving motors in the cleaning component, such as a driving motor for lifting the roller brush. The internal space of a household cleaning robot is limited. By reusing driving motors such as those for lifting the roller brush, the roller brush lifting and the shielding member and / or scraper bar movement can be achieved through different transmission mechanisms, thereby further saving space and improving the compactness of the internal structure of the cleaning robot.

[0133] In other embodiments of the present application, the transmission mechanism 320 may also be a screw transmission, a gear transmission, etc.; or the driving part 310 may drive the pull rope to move, thereby driving the shielding member 200 to move, etc.

[0134] In one embodiment, the drive mechanism 300 includes a stop structure comprising a sensing portion and a sensed portion. When the sensing portion senses the sensed portion, the drive unit 310 stops. By providing the sensed portion, the drive unit 310 can stop when the shielding member 200 moves to the first position and the second position, thereby maintaining the shielding member 200 in the first and second positions.

[0135] In another embodiment, a plurality of sensing parts are provided, so that the driving part 310 can stop when the shielding member 200 is at different positions between the first position and the second position, so as to adjust the position of the shielding member 200 as needed, and adjust the size of the suction force at the opening 110 according to the scene, so as to meet the use needs of multiple scenes.

[0136] See also Figure 3 In one embodiment, the cleaning assembly includes a scraper 600, which is disposed on the rear side of the housing 100. The scraper 600 has a lowered third position and a raised fourth position. A shielding plate is disposed on the front side of the housing 100, with the scraper 600 and shielding plate disposed on either side of the housing 100. The scraper 600 can trap dirt at the bottom of the housing 100, thereby preventing dirt from escaping the housing 100 and causing secondary contamination. Preferably, the scraper 600 is made of a flexible material, such as rubber, silicone, or plastic, to enhance the dirt trapping effect.

[0137] In one embodiment, the cleaning assembly includes a second cover plate 700, which is fixed on the shell 100. A gap is formed between the second cover plate 700 and the shell 100 to accommodate the movement of the scraper 600. The second cover plate 700 and the shell 100 provide guidance and limitation for the scraper 600 so that the scraper 600 moves along a predetermined path.

[0138] In one embodiment, the drive mechanism 300 drives the scraper 600 to move between the third and fourth positions. The shielding member 200 and the scraper 600 move in opposite directions in sync. When the shielding member 200 moves to the first position, the scraper 600 moves to the fourth position. When the shielding member 200 moves to the second position, the scraper 600 moves to the third position. For example, when the cleaning surface is a carpet, the shielding member 200 moves to the first position to absorb dirt deep inside the carpet. At this time, the suction force at the opening 110 is increased, allowing dirt deep inside the carpet to be drawn into the dust collection chamber. The scraper 600 then moves to the raised fourth position, i.e., a higher position, thereby meeting the cleaning requirements of the carpet.

[0139] See also Figure 6 In one embodiment, the transmission mechanism 320 includes a first link 321, a second link 322, a third link 323, and a fourth link 324. The first and fourth links 321 and 324 are fixedly connected to the output shaft of the drive unit 310. The second link 322 is rotatably connected to the first link 321, and the shielding member 200 is rotatably connected to the second link 322. The third link 323 rotates synchronously with the output shaft of the drive unit 310. The fourth link 324 is rotatably connected to the third link 323, and the scraper 600 is rotatably connected to the fourth link 324. Using a single transmission mechanism 320, the drive unit 310 simultaneously drives the shielding member 200 and the scraper 600, reducing the number of drive mechanisms 300, lowering costs, and improving the synchronization of the movement of the shielding member 200 and the scraper 600.

[0140] In one embodiment, the third connecting rod 323 is fixed to the first connecting rod 321 via a synchronization rod, and the second connecting rod 322 is rotatably connected to the synchronization rod so that the second connecting rod 322 rotates with the first connecting rod 321. The synchronization rod serves as both a connecting rod between the third connecting rod 323 and the first connecting rod 321 and a rotation axis for the second connecting rod 322, making the design of the transmission mechanism 320 more compact, reducing space occupation, and facilitating the design and utilization of the internal space of the cleaning device.

[0141] See also Figure 6In one embodiment, both the third connecting rod 323 and the first connecting rod 321 are eccentric wheel structures. Specifically, the third connecting rod 323 and the first connecting rod 321 are coaxial wheel-shaped structures, and the synchronization rod is located eccentrically of the wheel-shaped structures. The two eccentric wheel structures rotate synchronously, improving rotational stability and, in turn, stabilizing the movement of the shielding member 200 and the scraper 600.

[0142] In one embodiment, when the cleaning surface is a carpet, the shielding member 200 is in the first position. Carpets are more likely to harbor dirt, such as hair and debris, which tend to sink deep into the carpet. By moving the shielding member 200 to the first position, the cleaning effect of the carpet can be improved, thereby meeting the cleaning needs of the carpet.

[0143] See also Figure 10 and Figure 11 In one embodiment, the cleaning assembly includes a limiting member 800, which limits the position of the shielding member 200 so that the shielding member 200 moves between the first position and the second position.

[0144] In one embodiment, the limiting member 800 limits the position of the shielding member 200 by directly abutting against the limiting member 800. When the shielding member 200 moves to abut against the limiting member 800, the limiting member 800 restricts further movement of the shielding member 200, thereby limiting the position of the shielding member 200. It should be noted that the abutment between the shielding member 200 and the limiting member 800 can be achieved by the main body of the shielding member 200 abutting against the limiting member 800, such as when the limiting member 800 is disposed at the end of the moving path of the shielding member 200 and the main body of the shielding member 200 abuts against the limiting member 800 when the shielding member 200 moves to the first position or the second position; or it can be achieved by the protrusion or groove on the shielding member 200 abutting against the limiting member 800.

[0145] In one embodiment, the stopper 800 limits the position of the shielding member 200 by limiting the position of the transmission mechanism 320 or the scraper 600. For example, when the scraper 600 moves and abuts the stopper 800, the stopper 800 restricts further movement of the scraper 600, thereby limiting the position of the shielding member 200. Similarly, the abutment between the scraper 600 and the stopper 800 can be achieved by the main body of the scraper 600 abutting the stopper 800, or by a protrusion or groove on the scraper abutting the stopper 800.

[0146] In one embodiment, the limit member 800 can be set on the shell 100, the limit member 800 can also be set on the first cover plate 500, the limit member 800 can also be set on the second cover plate 700, and the limit member 800 can also include multiple ones, which are respectively set on one or more of the shell 100, the first cover plate 500 and the second cover plate 700.

[0147] In one embodiment, the limiting member 800 includes a first limiting portion 810 and a second limiting portion 820. When the shielding member 200 moves from the second position to the first position, the first limiting portion 810 limits the shielding member 200 to prevent further movement. When the shielding member 200 moves from the first position to the second position, the second limiting portion 820 limits the shielding member 200 to prevent further movement. By providing the first limiting portion 810 and the second limiting portion 820, the shielding member 200 can be limited in the first and second positions respectively, thereby ensuring that the shielding member 200 can move between the first and second positions.

[0148] See also Figure 11 In one embodiment, the first limiting portion 810 is arranged at the upper edge of the scraper 600 when it moves to the fourth raised position. The first limiting portion 810 can be arranged on the second cover plate 700 or on the shell 100. When the scraper 600 moves to the fourth raised position, the scraper 600 abuts against the first limiting portion 810, and then the first limiting portion 810 limits the further movement of the scraper 600; the shielding member 200 moves synchronously with the scraper 600 in opposite directions. When the scraper 600 abuts against the first limiting portion 810, the shielding member 200 is located at the first position, partially covering the opening 110. The second stopper 820 is disposed at the upper edge of the shielding member 200 when it moves to the second position. The second stopper 820 can be disposed on the first cover plate 500 or the housing 100. When the shielding member 200 moves from the first position to the second position, the shielding member 200 abuts against the second stopper 820, thereby limiting further movement of the shielding member 200. The first stopper 810 and the second stopper 820 are disposed on one side of the scraper 600 and the shielding member 200, respectively, and control the shielding member 200 to move synchronously with the scraper 600 in opposite directions, further reducing the number of stoppers and saving space. Furthermore, the first stopper 810 is disposed at the upper edge of the scraper 600 when it moves to the fourth position, while the second stopper 820 is disposed at the upper edge of the shielding member 200 when it moves to the second position. This can also prevent interference with the movement paths of the scraper 600 and the shielding member 200, thereby improving the smoothness of movement of the scraper 600 and the shielding member 200. The setting of the first limiting portion 810 and the second limiting portion 820 can ensure that the shielding member 200 and the scraper 600 have a larger contact area with the limiting portion 800, thereby reducing the pressure on the components when they abut against each other, reducing the probability of collision damage to the shielding member 200, the scraper 600 and the limiting portion 800, and improving their service life.

[0149] See also Figure 3 and Figure 6In one embodiment, a dust suction duct 130 is provided on the housing 100, and the opening 110 is connected to the dust suction duct 130. The dust suction duct 130 is connected to the dust box of the cleaning device, so that dirt is adsorbed into the dust box for collection, reducing the dirt contained in the dust suction chamber and reducing the risk of secondary contamination.

[0150] A second aspect of the present invention provides a cleaning device, comprising a device body and a cleaning assembly as described above, the cleaning assembly being mounted on the device body. The shielding member 200 of the cleaning assembly has a first position and a second position, which can change the air intake area of ​​the opening 110, thereby adjusting the suction force of the opening 110. For example, when the cleaning surface is a carpet, the shielding member 200 is in the first position, which increases the suction force of the opening 110. When the cleaning surface is a floor, the shielding member 200 is in the second position, which ensures that large particles can enter the dust collection chamber more quickly, thereby meeting the needs of cleaning dirt in different scenarios.

[0151] See also Figure 12 and Figure 13 The third aspect of the present invention provides a cleaning device, including a device body and a cleaning component installed on the device body, the cleaning component including a shell 100, a dust suction chamber is formed in the shell 100, and with the forward direction of the cleaning device as the front, the front wall of the shell 100 is provided with an opening 110 connected to the dust suction chamber, so that there is a gap between the front wall of the shell 100 and the cleaning surface. By setting the opening 110, the dirt on the front side of the shell 100 enters the dust suction chamber through the opening 110.

[0152] See also Figure 12 and Figure 13 The cleaning device further includes a shielding member 200 and a driving mechanism 300. The shielding member 200 is movably mounted on the device body and has a first position and a second position. When the shielding member 200 is in the first position, the ventilation area at the opening 110 of the covering portion is smaller than the ventilation area when the shielding member 200 is in the second position. When the shielding member 200 is in the first position, the covering portion of the opening 110 is covered, so that the ventilation area at the opening 110 is smaller than the ventilation area when the shielding member 200 is in the second position. That is, when the shielding member 200 is in the first position, the suction force at the opening 110 is increased, the adsorption capacity of dirt is improved, and the cleaning effect is improved, thereby meeting the cleaning needs of dirt in various scenarios and improving the cleaning effect. The driving mechanism 300 drives the shielding member 200 to move between the first position and the second position. By arranging the shielding member 200 and the driving mechanism 300 on the device body, there is no need to change the structure of the existing cleaning component, thereby improving the adaptability of the cleaning component.

[0153] In one embodiment, the shielding member 200 is rotatably connected to the device body, and the shielding member 200 is driven to rotate by the driving mechanism 300, so that the shielding member 200 rotates between the first position and the second position, thereby changing the covering of the opening 110 by the shielding member 200 to change the ventilation area of ​​the opening 110.

[0154] In one embodiment, the shielding member 200 is integrally formed and is made of a hard material, such as hard plastic or a hard rubber strip. In another embodiment, the shielding member 200 is formed of multiple components that are fixedly connected. The multiple components can be made of either hard or flexible materials, or partially hard and partially flexible materials. The selection is based on actual needs and can also be implemented with reference to the above embodiments.

[0155] In one embodiment, the drive mechanism 300 includes a drive unit 310 and a transmission mechanism 320. The drive unit 310 can utilize an existing drive device of the cleaning equipment, such as a cleaning component lifting motor. Alternatively, a separate drive unit 310 can be provided to drive the shielding member 200. The transmission mechanism 320 can be a gear transmission mechanism or a belt transmission mechanism. In another embodiment, the drive mechanism 300 includes only the drive unit 310, which is directly connected to the shielding member 200 through the drive unit 310, thereby driving the shielding member 200 to rotate.

[0156] The device body includes a chassis 900. A receiving cavity 910 is recessed inwardly on the side of the chassis facing the cleaning surface. The shielding member 200 is housed in the receiving cavity 910 when in the second position. When in the first position, the shielding member 200 partially covers the opening 110. A connecting shaft is provided on the chassis 900, through which the shielding member 200 is connected to the chassis, and the shielding member 200 is rotatable relative to the chassis.

[0157] The cleaning assembly of the present invention can adjust the position of the shielding member 200 according to different scenarios, thereby adjusting the ventilation area of ​​the opening 110 and adjusting the suction force of the opening 110 to meet the cleaning needs of multiple scenarios. Therefore, the present invention effectively overcomes some practical problems in the prior art and has high utilization value and practical significance.

[0158] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed in the present invention are intended to be covered by the claims of the present invention.
