Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on January 27, 2025, with application number 202510126171.7 and application name “A Self-Regulating Vacuum Cleaner”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present disclosure relates to the technical field of cleaning equipment, and in particular to a floor brush and a vacuum cleaner. Background Art

[0003] Cleaning equipment has the advantages of environmental protection, energy saving, high efficiency, etc. As people's awareness of household cleaning efficiency increases, cleaning equipment has gradually been widely used in daily production and life.

[0004] At present, a carpet brush corresponding to the carpet is provided in the cleaning device. In order to ensure that large particles enter, the carpet brush is provided with a stopper to enable the floor brush to move up and down, and the stopper is driven by a driving member to achieve the up and down movement.

[0005] However, current cleaning devices usually need to be equipped with sensors to sense the position of the block to know the current state of the cleaning device, and the sensor needs to be set at the position of the block. The size of the floor brush is large, and the miniaturization of the floor brush and the vacuum cleaner cannot be achieved. Summary of the invention

[0006] The present disclosure provides a floor brush and a vacuum cleaner, wherein the floor brush comprises:

[0007] A floor brush housing, having a dust collecting port and an air inlet, wherein the air inlet is located above the dust collecting port, the air inlet and the dust collecting port are respectively connected to the interior of the floor brush housing, a block is provided at the dust collecting port, and an air plate is provided at the air inlet;

[0008] A driving member, which is drivingly connected to the stopper and the air plate to drive the stopper to open or close the dust collecting port and to drive the air plate to open or close the air inlet;

[0009] A display component displays the state of the floor brush based on the movement of at least one of the driving member, the stopper and the air plate.

[0010] The floor brush and vacuum cleaner provided by the embodiments of the present disclosure, firstly, directly control the movement of the block and the air plate through a driving member, rather than requiring a sensor as in a conventional cleaning device, which is conducive to miniaturization of the vacuum cleaner. In the case where the embodiment of the present disclosure does not provide a sensor, the floor brush does not need to design a related circuit, and further does not need to provide sensors at different positions of the block and the air plate. The space saved can increase the size of the block and the air plate, and thus improve the sealing performance of the block and the air plate.

[0011] Secondly, the opening and closing of the stopper and the air plate can be controlled by the driving part, and the state can be switched according to the different surfaces to be cleaned (such as cement floors, carpets, blankets, etc.). It can not only protect items such as carpets and blankets, but also avoid wasting the suction power of the vacuum cleaner host.

[0012] In addition, the current state of the floor brush can be judged by the display component according to the moving distance of the driving member, the stopper or the air plate. The user can understand the working state of the floor brush without complicated operation or additional equipment, and the operation is simple and intuitive. The display component can judge the state of the floor brush in combination with the existing stopper and air plate, and the cost is low.

[0013] In the above-mentioned floor brush, optionally, the stopper and the air plate are connected via a transmission member, and the driving member is connected to the air plate and the stopper via the transmission member;

[0014] The display component is connected to the transmission component and is used to display the opening and closing status of the dust collecting port and the air inlet.

[0015] Through the above settings, users only need to adjust the driving part to control the opening and closing of the stopper and the air plate through the transmission part. Users can intuitively understand the working mode of the floor brush without additional devices, further improving the user experience.

[0016] In the above-mentioned floor brush, optionally, the transmission member moves in a first direction or a second direction, the first direction is opposite to the second direction; the stopper moves in a third direction, the air plate moves in a fourth direction, the third direction is opposite to the fourth direction; the first direction intersects with the third direction;

[0017] The driving member is used to drive at least one of the stopper, the gas plate, and the transmission member to move at least one of the stopper and the gas plate.

[0018] Through the above arrangement, the transmission member, the block and the air plate have different moving directions, the transmission member can occupy a smaller size in the vertical direction, the height of the floor brush can be reduced, and it is conducive to miniaturization of the vacuum cleaner.

[0019] In the above-mentioned floor brush, optionally, the transmission member includes a plurality of moving segments, and the plurality of moving segments are connected end to end in sequence;

[0020] The plurality of moving segments respectively correspond to the opening and closing states of the stopper and the gas plate, so that the display component displays different moving segments to display the opening and closing states of the stopper and the gas plate.

[0021] Through the above settings, multiple moving segments correspond to different distances of the transmission parts in the horizontal direction. Users can judge the position of the block and the air plate by observing the moving segments they see, and then judge the opening and closing status of the dust collection port and the air inlet. The above method can be completed without additional equipment or complicated operations. Users can better control the use of the floor brush through intuitive display and improve the user experience.

[0022] In the above-mentioned floor brush, optionally, at least one of the shapes and colors of the plurality of moving segments is different.

[0023] Through the different designs of shapes and colors of multiple moving segments, the floor brush can intuitively feedback the current working status to the user, improving the user experience and ease of operation.

[0024] In the above-mentioned floor brush, optionally, the display component includes a hollow structure, the hollow structure is arranged corresponding to the transmission member, and the hollow structure is used to expose at least one of the plurality of moving segments.

[0025] Through the above arrangement, by exposing different moving segments, the display component can intuitively reflect the state of the transmission member, and the user can quickly adjust the working mode of the floor brush according to the displayed moving segments.

[0026] In the above-mentioned floor brush, optionally, the hollow structure includes a plurality of hollow areas, the plurality of hollow areas correspond one-to-one to the plurality of moving segments, and the plurality of hollow areas are arranged in sequence along the first direction.

[0027] Through the above arrangement, the display component can intuitively and accurately reflect the different moving sections of the transmission component through different hollow areas, thereby judging the opening and closing states of the block and the gas plate.

[0028] In the above-mentioned floor brush, optionally, the display component further includes light-transmitting members corresponding to the plurality of hollow areas, the plurality of light-transmitting members have at least one different shape or color, and the plurality of light-transmitting members correspond one-to-one to the plurality of moving segments;

[0029] The moving section is used to cover the corresponding light-transmitting member to indicate the opening and closing status of the stopper and the gas plate.

[0030] Through the above arrangement, the light-transmitting member can improve the visibility and aesthetics of the display, making it easier for the user to identify the current moving segment. Different shapes or colors enable the user to quickly identify different moving segments. The above arrangement allows the user to intuitively judge the state of the floor brush.

[0031] In the above-mentioned floor brush, optionally, the display component further includes a display screen and a sensor, the sensor is located between the floor brush housing and the transmission member, and the transmission member is used to sense the positions of different moving sections;

[0032] The display screen is electrically connected to the sensor, and is used to display the opening and closing states of the stopper and the gas plate according to the positions of the different moving segments.

[0033] Through the above settings, the display screen can display more complex patterns or texts according to needs, and can more intuitively display the opening and closing status of the block and the gas plate, shortening the user's judgment time. The sensor can detect the moving distance of different moving segments in real time, and can achieve precise control of the moving distance, thereby improving the accuracy of the moving position of the block and the gas plate.

[0034] In the above-mentioned floor brush, optionally, a first guide groove and a second guide groove are provided on the transmission member, and a first boss and a second boss which are adapted to the first guide groove and the second guide groove are respectively provided on the stop block and the air plate, and the first boss is movably embedded in the first guide groove, and the second boss is movably embedded in the second guide groove.

[0035] Through the above-mentioned setting, the cooperation between the boss and the guide groove can ensure the stability of the block and the air plate during movement, reduce shaking and deviation, and thus ensure the reliability of transmission of the transmission parts and reduce failures caused by mechanical clearance.

[0036] In the above-mentioned floor brush, optionally, the first guide groove includes a first guide groove section and a first avoidance groove section, one end of the first avoidance groove section is connected to the first guide groove section, the first avoidance groove section is arranged along the first direction, and the extension direction of the first guide groove section intersects with the first direction and the third direction;

[0037] When the first protrusion abuts against one end of the first guide slot section away from the first avoidance slot section, the stopper blocks the dust collecting port, and the dust collecting port is in a closed state;

[0038] When the first boss is located in the first guide groove and the transmission member moves along the first direction, the first boss moves in the first guide groove section toward the first avoidance groove section, so that the block opens the dust collecting port, and the dust collecting port is in an open state.

[0039] By moving the first protrusion in the first guide groove section and the first avoidance groove section, the stopper can open or close the dust collection port, so that the floor brush can adapt to different usage scenarios.

[0040] In the above-mentioned floor brush, optionally, the second guide groove includes a second guide groove section and a second avoidance groove section, one end of the second avoidance groove section is connected to the second guide groove section, the second avoidance groove section is arranged along the first direction, and the extension direction of the second guide groove section intersects with the first direction and the third direction;

[0041] When the second protrusion is located in the second avoidance groove section, the air plate blocks the air inlet, and the air inlet is in a closed state;

[0042] When the second boss is located in the second guide slot section and the transmission member moves along the first direction, the second boss moves away from the second avoidance slot section in the second guide slot section, so that the air plate opens the air inlet, and the air inlet is in an open state.

[0043] By moving the second protrusion in the second guide groove section and the second avoidance groove section, the air plate can open or close the air inlet, so that the floor brush can adapt to different usage scenarios.

[0044] In the above-mentioned floor brush, optionally, when the first protrusion moves from the end of the first guide groove section away from the first avoidance groove section to the connection between the first guide groove section and the first avoidance groove section, the displacement of the stopper in the first direction is a first distance, and the first distance is the same as the length of the first avoidance groove section;

[0045] When the second boss moves from one end where the second guide groove section is connected to the second avoidance groove section to one end of the second guide groove section away from the second avoidance groove section, the displacement of the gas plate in the first direction is a second distance, and the second distance is the same as the length of the second avoidance groove section.

[0046] In this way, in the first direction, the moving distance of the first boss in the first guide groove section is the same as the moving distance in the first avoidance groove section; at the same time, the moving distance of the air plate in the second guide groove section is the same as the moving distance of the air plate in the second avoidance groove section, thereby achieving the same size of multiple moving sections of the transmission member.

[0047] Through the above arrangement, the dimensions of the multiple moving sections are the same, which can ensure the balance of the transmission parts during movement, reduce shaking, and reduce errors. In addition, the driving part can control the opening and closing of the dust collection port and the air inlet by moving the fixed size, without the need for precise control of the driving part, which can reduce the cost of controlling the driving part.

[0048] In the above-mentioned floor brush, optionally, the angle between the extension direction of the first guide groove section and the extension direction of the first avoidance groove section is A, the length of the first guide groove section is a1, the length of the second avoidance groove section is b2, and the relationship between a1, b2 and A satisfies: a1*cosA=b2;

[0049] and,

[0050] The angle between the extension direction of the second guide groove section and the extension direction of the second avoidance groove section is B, the length of the second guide groove section is b1, the length of the first avoidance groove section is a2, and the relationship between b1, a2 and B satisfies: b1*cosB=a2.

[0051] Thus, in the first direction, the moving distance of the first protrusion in the first guide slot section is the same as the moving distance in the first avoidance slot section, and the moving distance of the second protrusion in the second guide slot section is the same as the moving distance in the second avoidance slot section. Correspondingly, the distances of the two moving sections corresponding to the transmission member are the same, so as to facilitate the setting of the corresponding display component. Thus, the sizes of the two moving sections corresponding to the transmission member are the same;

[0052] If a1*cosA=b2 and b1*cosB=a2, when the block moves upward, the air plate does not move, and when the block does not move, the air plate starts to move downward. In this way, the movement of the block and the air plate can be performed alternately, making the structure of the floor brush more compact, which is conducive to the miniaturization of the floor brush and the vacuum cleaner.

[0053] In the above-mentioned floor brush, optionally, the driving member includes a driver and a screw rod, the driver is arranged in the floor brush housing, the screw rod is connected to the driver, the transmission member is threadedly connected to the screw rod, and the axis of the screw rod is parallel to the first direction;

[0054] When the driver drives the screw rod to rotate forward or reverse, the transmission member moves along the axis of the screw rod;

[0055] or,

[0056] The driving member includes a driver and a pull rope, the driver is arranged on the floor brush housing, two ends of the pull rope are connected to opposite sides of the transmission member, the pull rope is wound around the output shaft of the driving member, the extension direction of the output shaft of the driving member is perpendicular to the first direction, and the pull rope is extended along the first direction;

[0057] When the driver drives the pull rope to rotate in a positive direction, the transmission member moves along a first direction;

[0058] When the driver drives the pull rope to rotate in the reverse direction, the transmission member moves along the second direction.

[0059] In a second aspect, an embodiment of the present disclosure further provides a vacuum cleaner, comprising a vacuum cleaner main unit, a vacuum tube and the floor brush, wherein the vacuum cleaner main unit is connected to the floor brush via the vacuum tube.

[0081] In the related art, a plurality of components, such as an opening and closing plate, need to be provided on the floor brush, and the opening and closing plate usually needs to be provided on the outside of the floor brush, so that the surface space of the floor brush is relatively tight.

[0082] To this end, the floor brush and vacuum cleaner provided in the embodiment of the present disclosure directly control the movement of the block and the air plate through a driving member, rather than relying on sensors provided in traditional cleaning equipment. Since the sensor and its related components are eliminated, the size of the floor brush can be reduced, and the space occupied by the vacuum cleaner can be reduced, which is conducive to miniaturization of the vacuum cleaner.

[0083] In the case where the sensor is not provided in the embodiment of the present disclosure, the floor brush does not need to design related circuits. Through the display component, the state of the floor brush can be judged in combination with the existing block and gas plate, and the cost is low. In addition, since there is no need to provide sensors at different positions of the block and gas plate, the saved space can increase the size of the block and gas plate, thereby improving the sealing performance of the block and gas plate.

[0084] In order to make the purpose, implementation mode and advantages of the present disclosure clearer, the exemplary implementation mode of the present disclosure will be clearly and completely described below in conjunction with the drawings in the exemplary embodiments of the present disclosure. Obviously, the described exemplary embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments.

[0088] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, unless otherwise specified, "plurality" means two or more.

[0089] In the description of the present disclosure, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0090] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0091] In a first aspect, an embodiment of the present disclosure provides a vacuum cleaner, which includes a vacuum cleaner main unit, a vacuum tube, and a floor brush 10 .

[0092] Specifically, the vacuum cleaner main unit is connected to the floor brush 10 through a vacuum tube. The vacuum cleaner main unit includes a vacuum source and a dust cup for generating vacuum suction, the vacuum source is connected to the dust cup, and the dust cup can be connected to the external environment through the vacuum tube. The vacuum suction generated by the vacuum source is transmitted to the floor brush 10 by the dust cup and the vacuum tube to absorb dirt.

[0093] Reference Figure 1 In a second aspect, the disclosed embodiment further provides a floor brush 10, which is connected to a vacuum cleaner host. The vacuum cleaner host can rotate relative to the floor brush 10, and the user can adjust the relative position between the vacuum cleaner host and the floor brush 10 according to the usage scenario.

[0094] It is understandable that the floor brush 10 is suitable for performing cleaning actions on the surface to be cleaned to achieve a cleaning effect. The surface to be cleaned may be a floor or wall with different degrees of roughness, or a carpet or blanket with different lengths or types, or the surface of an object to be cleaned. The present disclosure does not specifically limit the type of surface to be cleaned. The above-mentioned cleaning action may be a vacuuming action, a mopping action, or a vacuuming and mopping action performed simultaneously to ensure the cleaning efficiency of the floor brush 10.

[0095] In the embodiment of the present disclosure, the above-mentioned cleaning action may be a vacuuming action.

[0096] Reference Figure 2 Specifically, the floor brush 10 includes a roller brush, a floor brush housing 100 , a driving member 200 and a display component 600 .

[0097] It is understood that the cleaning device can move along a preset direction of travel on the surface to be cleaned to complete the cleaning process. The preset direction of travel refers to the direction of travel of the cleaning device. In the preset direction of travel, the roller brush is usually located at the front side of the floor brush 10. The roller brush is rotatably connected to the floor brush housing 100, and the roller brush is used to clean dirt located on the surface to be cleaned.

[0098] Reference Figure 3The floor brush housing 100 has a dust collecting port 120 and an air inlet 130. The dust collecting port 120 and the air inlet 130 are both arranged on the front side of the floor brush housing 100, that is, on the front side of the roller brush, and are both connected to the floor brush housing 100, that is, the floor brush housing 100 forms a cavity 110, and the dust collecting port 120 and the air inlet 130 are both connected to the cavity 110. The front side refers to the front side of the floor brush 10 in the preset direction of travel. The air inlet 130 is located above the dust collecting port 120, and the air inlet 130 can reduce the vacuum degree to a certain threshold to reduce the motor load without losing the cleaning ability.

[0099] Reference Figure 4 It is understandable that a blocking member 131, such as a filter, a partition, etc., may be provided at the position of the air inlet 130 to prevent clogging by long-haired fibers or particles. The blocking member 131 may be provided on the floor brush housing 100 or on the display component 600.

[0100] A stopper 300 is provided at the dust collecting port 120, and an air plate 400 is provided at the air inlet 130. The driving member 200 is drivingly connected to the stopper 300 and the air plate 400 to drive the stopper 300 to open or close the dust collecting port 120 and drive the air plate 400 to open or close the air inlet 130.

[0101] It should be noted that the block 300 can open or close the dust collection port 120 in various ways. For example, the block 300 can move relative to the brush housing 100, or can rotate relative to the brush housing 100, so that the block 300 can close the dust collection port 120 or open the dust collection port 120, thereby realizing the opening or closing of the dust collection port 120.

[0102] In the embodiment of the present disclosure, the stopper 300 moves linearly toward or away from the surface to be cleaned, thereby closing or opening the dust collection port 120 .

[0103] It is understandable that the way the air plate 400 opens or closes the air inlet 130 can refer to the way between the stopper 300 and the dust collecting port 120, which will not be elaborated here.

[0104] It should be noted that the order in which the driver 200 drives the block 300 and the gas plate 400 can be arbitrary. For example, the driver 200 can first drive the block 300 to move, and then drive the gas plate 400 to move; for another example, the driver 200 can drive the block 300 and the gas plate 400 to move at the same time; for another example, the driver 200 can first drive the gas plate 400 to move, and then drive the block 300 to move. In the embodiment of the present disclosure, the driver 200 can first drive the block 300 to move (refer to Figure 5 and Figure 7 ), and then drive the gas plate 400 to move (refer to Figure 7as well as Fig. 9 In this way, the gas plate 400 can adaptively adjust the moving distance according to the position of the stopper 300.

[0105] By simultaneously controlling the movement of the stopper 300 and the air plate 400 through the driving member 200, the user can adjust the opening and closing states of the dust collecting port 120 and the air inlet 130 according to different needs, thereby adjusting the size of the negative pressure.

[0106] In some embodiments, when cleaning a surface to be cleaned with large particles of garbage, the block 300 opens the dust collection port 120 so that large particles of garbage can enter the dust cup through the dust collection port 120 for collection. At the same time, the air plate 400 closes the air inlet 130 to maintain a large suction force to absorb dirt.

[0107] It should be noted that large particles of garbage may refer to garbage with a height less than or equal to a preset value, and the preset value may be determined based on the distance between the floor brush 10 and the surface to be cleaned. In the disclosed embodiment, the preset value may be set to a range of 2-7 mm.

[0108] It is understandable that there are many possibilities for the surface to be cleaned, including but not limited to cement floors, tile floors, and carpets and rugs located on the ground.

[0109] It should be noted that, since long-haired fibers are usually provided on blankets and carpets, the long-haired fibers are easily entangled by the roller brush, causing the blankets and carpets to be damaged. In addition, if the height and density of the long-haired fibers reach a certain level, the floor brush 10 will not be able to separate from the blankets and carpets, causing the vacuum source to be overloaded. It should be noted that if the fibers on the blankets and carpets are relatively low, the dust collection port 120 may not be opened.

[0110] To this end, in some embodiments, when cleaning a blanket or carpet and waiting for the cleaning surface, the block 300 opens the dust collection port 120, so that the long-haired fibers on the blanket or carpet can pass through the floor brush 10 smoothly through the dust collection port 120, and prevents large particles of garbage with a larger rolling brush size from entering the dust cup through the dust collection port 120 for collection. At the same time, the air plate 400 opens the air inlet 130 to reduce the vacuum degree and thus reduce the suction force, thereby avoiding the absorption of long-haired fibers on the blanket or carpet, and ensuring that the blanket or carpet can pass through the floor brush 10 without damage.

[0111] In some embodiments, when cleaning a surface to be cleaned that does not fall into the above situation, the block 300 closes the dust collection port 120 and the air plate 400 closes the air inlet 130, and the vacuum degree is relatively large, so that the floor brush 10 absorbs dirt with a relatively large suction force.

[0112] Furthermore, the display component 600 can display the state of the floor brush 10, which means adjusting different cleaning modes according to the aforementioned different surfaces to be cleaned. Specifically, the display component 600 can display the state of the floor brush 10 based on the movement of at least one of the driving member 200, the stopper 300 and the air plate 400.

[0113] It is understandable that, according to the foregoing content, the block 300 and the gas plate 400 are both connected to the driving member 200. When the display component 600 is connected to the driving member 200, the display component 600 can judge the current state of the floor brush 10 according to the moving distance of the block 300 driven by the driving member 200 and the moving distance of the gas plate 400 driven by the driving member 200.

[0114] Reference Figure 6 , Figure 8 as well as Fig.10 In other embodiments, the display component 600 is connected to the stopper 300 and the air plate 400 at the same time, and the display component 600 can judge the current state of the floor brush 10 according to the moving distance of the stopper 300 and the moving distance of the air plate 400. In addition, the display component 600 can also be connected to the driving member 200 while being connected to at least one of the stopper 300 and the air plate 400, and can also judge the current state of the floor brush 10 according to the moving distance of the stopper 300 and the air plate 400 driven by the driving member 200.

[0115] In another embodiment, the stopper 300 and the gas plate 400 can be connected in linkage. That is, the stopper 300 can drive the gas plate 400 to move after moving a certain distance, or the gas plate 400 can drive the stopper 300 to move after moving a certain distance. According to the above content, the driving member 200 can first drive the stopper 300 to move, and then drive the gas plate 400 to move. Therefore, the linkage between the stopper 300 and the gas plate 400 can mean that the stopper 300 can drive the gas plate 400 to move after moving a certain distance.

[0116] It can be seen from the above contents that the floor brush 10 and the vacuum cleaner provided in the embodiment of the present disclosure, firstly, directly control the movement of the stopper 300 and the air plate 400 through the driving member 200, eliminating the reliance on sensors for detecting cleaning conditions (e.g., the type of the surface to be cleaned, the type of garbage on the surface to be cleaned, etc.) in traditional cleaning equipment. Since the sensor and its related components are eliminated, the size of the floor brush 10 can be reduced, and the space occupied by the vacuum cleaner can be reduced, which is conducive to miniaturization of the vacuum cleaner.

[0117] Secondly, the opening and closing of the stopper 300 and the air plate 400 can be controlled by the driving member 200, and the state can be switched according to different surfaces to be cleaned (such as cement floors, carpets, blankets, etc.). This can not only protect items such as carpets and blankets, but also avoid wasting the suction power of the vacuum cleaner host.

[0118] In addition, the current state of the floor brush 10 is determined by the display part 600 according to the moving distance of the driving member 200, the stopper 300 or the air plate 400. The user can understand the working state of the floor brush 10 without complicated operations or additional equipment, and the operation is simple and intuitive.

[0119] Reference Figure 5 , Figure 6 As an optional embodiment, in order to realize the linkage between the block 300 and the air plate 400, the floor brush 10 also includes a transmission member 500, the block 300 and the air plate 400 are connected through the transmission member 500, and the driving member 200 is connected to the air plate 400 and the block 300 through the transmission member 500.

[0120] It should be noted that the movement directions corresponding to the opening of the dust collecting port 120 and the air inlet 130 and the closing of the dust collecting port 120 and the air inlet 130 are opposite, that is, the transmission member 500 can move back and forth.

[0121] According to the above content, the stopper 300 moves in front. On this basis, the working process of the transmission member 500 is as follows:

[0122] Reference Figure 5 , Figure 6 , Figure 7 as well as Figure 8 When the dust collecting port 120 needs to be opened, the transmission member 500 moves under the driving action of the driving member 200, and the moved transmission member 500 can first drive the stopper 300 to move, so that the stopper 300 can open and close the dust collecting port 120;

[0123] Reference Figure 7 , Figure 8 , Fig. 9 as well as Fig.10 When the air inlet 130 needs to be opened, on the basis of the block 300 opening the dust collecting port 120 , the transmission member 500 continues to move until it drives the air plate 400 to move, so that the air plate 400 can open the air inlet 130 .

[0124] Reference Fig. 9 , Fig.10 , Figure 7 as well as Figure 8 When the air inlet 130 needs to be closed, on the basis of the air plate 400 opening the air inlet 130 , the transmission member 500 moves in the reverse direction until it drives the air plate 400 to move in the reverse direction, so that the air plate 400 can restore its position and then close the air inlet 130 .

[0125] Reference Figure 7 , Figure 8 , Figure 5 as well as Figure 6When the dust collecting port 120 needs to be closed, on the basis that the air plate 400 closes the air inlet 130 and the block 300 opens the dust collecting port 120, the transmission member 500 moves in the reverse direction until it drives the block 300 to move in the reverse direction, so that the block 300 can restore its position and then close the dust collecting port 120.

[0126] Furthermore, the display component 600 is connected to the transmission component 500 to display the opening and closing states of the dust collection port 120 and the air inlet 130. As can be seen from the foregoing, the transmission component 500 has different positions in the foregoing different states. Therefore, the display component 600 can obtain the opening and closing states of the dust collection port 120 and the air inlet 130 by simply connecting the transmission component 500.

[0127] Through the above arrangement, the user only needs to adjust the driving member 200 to simultaneously control the opening and closing of the stopper 300 and the air plate 400 through the transmission member 500. The user can intuitively understand the working mode of the floor brush 10 without additional devices, further improving the user experience.

[0128] Specifically, according to the foregoing content, different types of surfaces to be cleaned have height differences, so the moving direction of the block 300 refers to the height direction, that is, the vertical direction. That is, in the embodiment of the present disclosure, the third direction Y3 and the fourth direction Y4 both extend in the vertical direction. It should be noted that the block 300 needs to move away from the surface to be cleaned so that large particles of garbage, blankets, carpets, etc. can pass smoothly. When the floor brush 10 is located on the surface to be cleaned, the block 300 needs to move up to open the dust collection port 120, that is, the third direction Y3 is vertically upward.

[0129] In some embodiments, the moving directions of the stopper 300 and the gas plate 400 may be the same or opposite.

[0130] For example, when the stopper 300 and the air plate 400 move in the same direction, the transmission member 500 may also extend in the vertical direction. At this time, the transmission member 500 may move upward until the stopper 300 is driven to move upward to open the dust collection port 120, and then the transmission member 500 continues to move upward until the air plate 400 is driven to move upward to open the air inlet 130. Then, the transmission member 500 moves in the opposite direction, that is, downward, to close the air inlet 130 and the dust collection port 120 in sequence.

[0131] Reference Figure 5-Figure 10, illustratively, the movement directions of the stopper 300 and the gas plate 400 are different, that is, the stopper 300 moves along the third direction Y3, and the gas plate 400 moves along the fourth direction Y4, and the third direction Y3 is opposite to the fourth direction Y4, that is, the fourth direction Y4 is vertically downward. At this time, the transmission member 500 can be located between the stopper 300 and the gas plate 400, and the directions of the transmission member 500, the stopper 300, and the gas plate 400 are all different, so that the gas plate 400 moves downward after the stopper 300 moves upward. That is, the transmission member 500 moves along the first direction X1 or the second direction X2, and the first direction X1 is opposite to the second direction X2; the first direction X1 intersects with the third direction Y3. The third direction Y3 and the fourth direction Y4 can be any angles intersecting with the first direction X1. The vertical direction is taken as an example below, that is, the first direction X1 and the second direction X2 extend in the horizontal direction.

[0132] It can be understood that in the above manner, the transmission member 500 has a different moving direction from the block 300 and the air plate 400, and the transmission member 500 can occupy a smaller size in the vertical direction, which can reduce the height of the floor brush 10 and is conducive to miniaturization of the vacuum cleaner.

[0133] It should be noted that, on the basis of the linkage between the stopper 300 and the air plate 400 through the transmission member 500, the driving member 200 can drive any one of the three to complete the aforementioned process, that is, the driving member 200 can be used to drive at least one of the stopper 300, the air plate 400, and the transmission member 500 to move at least one of the stopper 300 and the air plate 400. In this way, the user can select a component drive connection with a larger activity space according to the actual situation of the floor brush 10.

[0134] Reference Figure 2 In some embodiments, in order to ensure that the stopper 300 and the gas plate 400 can move along a preset direction, the stopper 300 further includes a first limiting portion 320, the floor brush housing 100 has a first limiting groove 140, the depth direction of the first limiting groove 140 is the first direction X1, and the first limiting portion 320 is movably embedded in the first limiting groove 140;

[0135] When the stopper 300 moves along the third direction Y3 or the fourth direction Y4 , the first limiting portion 320 moves in the first limiting groove 140 .

[0136] Furthermore, the number of the first limiting portions 320 and the number of the first limiting grooves 140 are both two, the two first limiting portions 320 are located on both sides of the stopper 300 , and the two first limiting portions 320 are movably embedded in the two first limiting grooves 140 , respectively.

[0137] Correspondingly, the gas plate 400 further includes a second limiting portion 420, the floor brush housing 100 has a second limiting groove 150, the depth direction of the second limiting groove 150 is the first direction X1, and the second limiting portion 420 is movably embedded in the second limiting groove 150;

[0138] When the gas plate 400 moves along the third direction or the fourth direction Y4, the second limiting portion 420 moves in the second limiting groove 150.

[0139] The number of the second limiting parts 420 and the number of the second limiting grooves 150 are both two. The two second limiting parts 420 are located on both sides of the gas plate 400 , and the two second limiting parts 420 are movably embedded in the two second limiting grooves 150 , respectively.

[0140] Reference Fig.11 As an optional embodiment, the transmission member 500 includes a plurality of moving segments 501, and the plurality of moving segments 501 are connected end to end in sequence. It is understandable that the sizes of the plurality of moving segments 501 may be different, and different moving segments 501 may be adjusted according to the moving distance of the stopper 300 and the gas plate 400.

[0141] The plurality of moving segments 501 correspond to the opening and closing states of the stopper 300 and the gas plate 400 respectively, so that the display component 600 displays different moving segments 501 to display the opening and closing states of the stopper 300 and the gas plate 400 .

[0142] Exemplarily, the transmission member 500 has at least three moving sections 501. According to the foregoing, the first moving section 501 corresponds to the case where the block 300 closes the dust collecting port 120 and the air plate 400 closes the air inlet 130, for example, the surface to be cleaned is not a blanket, carpet, etc. and there are no large particles of garbage on the surface to be cleaned. The second moving section 501 corresponds to the case where the block 300 maintains the dust collecting port 120 and the air plate 400 closes the air inlet 130, for example, there are large particles of garbage on the surface to be cleaned. The third moving section 501 corresponds to the case where the block 300 opens the dust collecting port 120 and the air plate 400 opens the air inlet 130, for example, the surface to be cleaned is a blanket, carpet, etc.

[0143] It is understandable that the aforementioned multiple moving segments 501 correspond to different distances of the transmission member 500 in the horizontal direction. That is, the user can judge the position of the block 300 and the air plate 400 by observing the moving segments 501, and then judge the opening and closing status of the dust collection port 120 and the air inlet 130. The above method can be completed without additional equipment or complicated operations. The user can better control the use of the floor brush 10 through intuitive display and improve the use experience.

[0144] Reference Fig.11 As an optional implementation, at least one of the shapes and colors of the multiple moving segments 501 is different.

[0145] In some embodiments, the multiple moving segments 501 of the transmission member 500 are different in shape. For example, one moving segment 501 may be circular, another may be square, or have other geometric shapes. The different shapes allow the display component 600 to intuitively distinguish different moving segments 501, thereby clearly reflecting the current state of the floor brush 10. The user can quickly identify the working state of the floor brush 10 by the difference in shape without additional learning costs.

[0146] In some embodiments, the multiple moving segments 501 of the transmission member 500 are different in color. For example, one moving segment 501 may be red, another may be green, or other contrasting colors may be used. Different colors allow the display component 600 to intuitively distinguish different moving segments 501, thereby clearly reflecting the current opening and closing state. The user can quickly identify the working state of the floor brush 10 by the difference in color without additional learning costs.

[0147] In some embodiments, the multiple moving segments 501 of the transmission member 500 are different in shape and color. For example, one moving segment 501 may be round and red, and another moving segment 501 may be square and green, etc. For related content, please refer to the above part, and no further description is given here.

[0148] It should be noted that the color or shape of the moving segment 501 can be selected according to actual conditions, and the embodiment of the present disclosure does not limit this.

[0149] By designing the multiple moving segments 501 with different shapes and colors, the floor brush 10 can intuitively provide the user with feedback on the current working status, thereby improving the user experience and ease of operation.

[0150] Reference Figure 4 As an optional embodiment, the display component 600 includes a hollow structure 610, which means a hole or opening is formed. The hollow structure 610 allows the user to directly see the moving section 501 of the transmission member 500, so as to intuitively understand the opening and closing status of the stopper 300 and the gas plate 400.

[0151] Furthermore, the hollow structure 610 is arranged corresponding to the transmission member 500 , which means that the position of the hollow structure 610 corresponds to the moving path of the transmission member 500 , ensuring that the hollow structure 610 can accurately expose the moving section 501 of the transmission member 500 .

[0152] The hollow structure 610 is used to expose at least one of the multiple moving segments 501, that is, the size of the hollow structure 610 can expose only one moving segment 501, or can expose multiple moving segments 501. The user can intuitively see the current moving segment 501 through the hollow structure 610, so as to understand the opening and closing status of the stopper 300 and the gas plate 400.

[0153] Through the above arrangement, by exposing different moving segments 501 , the display component 600 can intuitively reflect the state of the transmission member 500 , and the user can quickly adjust the working mode of the floor brush 10 according to the displayed moving segments 501 .

[0154] The following description is given by taking the hollow structure 610 to expose the plurality of moving segments 501 .

[0155] Reference Figure 4 As an optional embodiment, the hollow structure 610 includes a plurality of hollow areas 611. The hollow areas 611 may be openings of different shapes or sizes, and are used to expose the moving section 501 of the transmission member 500. The user can quickly identify the working state of the floor brush 10 through the different hollow areas 611. The user can quickly identify the working state of the floor brush 10 through the different hollow areas 611.

[0156] The plurality of hollow areas 611 correspond to the plurality of moving segments 501 one by one, ensuring that when the transmission member 500 moves to a specific position, the corresponding hollow area 611 exposes the moving segment 501 .

[0157] The plurality of hollow regions 611 are sequentially arranged along the first direction X1 to ensure that when the transmission member 500 moves along the first direction X1 , different hollow regions 611 will sequentially expose the corresponding moving segments 501 .

[0158] Through the above arrangement, the display component 600 can intuitively and accurately reflect the different moving sections 501 of the transmission member 500 through different hollow areas 611, thereby judging the opening and closing states of the stopper 300 and the gas plate 400.

[0159] It should be noted that the hollow area 611 can form a pattern or text for the user to quickly judge, so as to increase the speed at which the user judges the opening and closing status.

[0160] Reference Figure 4 As an optional implementation, the display component 600 further includes a light-transmitting member 620 corresponding to the plurality of hollow regions 611, and the light-transmitting member 620 is used to enhance the display effect.

[0161] It can be understood that the light-transmitting element 620 can improve the visibility and aesthetics of the display, making it easier for the user to identify the current moving segment 501 .

[0162] It should be noted that the light-transmitting element 620 may be made of transparent or semi-transparent material to ensure that light can pass through, thereby improving display visibility.

[0163] At least one of the shapes and colors of the plurality of light-transmitting members 620 is different, and the different shapes or colors enable the user to quickly identify the different moving segments 501, thereby judging the opening and closing states of the stopper 300 and the gas plate 400. The plurality of light-transmitting members 620 correspond one-to-one to the plurality of moving segments 501, ensuring that the display component 600 can accurately reflect the current moving segment 501 of the transmission member 500, thereby improving accuracy.

[0164] The moving section 501 is used to block the corresponding light-transmitting member 620 to indicate the opening and closing state of the stopper 300 and the gas plate 400. That is, when the transmission member 500 moves to a specific position, the moving section 501 blocks the corresponding light-transmitting member 620, thereby indicating the opening and closing state of the stopper 300 and the gas plate 400.

[0165] It should be noted that, for a better display effect, the display component 600 is located outside the transmission component 500, and the display component 600 can protect the transmission component 500. In this case, the moving segment 501 shielding the light-transmitting component 620 means that the moving segment 501 is located at the rear side of the light-transmitting component 620 in the user's sight. The moving segment 501 can be set to an opaque structure, so that when the moving segment 501 is located behind the light-transmitting component 620, the brightness of the light-transmitting component 620 is weaker than that of other light-transmitting components 620, so as to distinguish different light-transmitting components 620.

[0166] It is understandable that, in order to protect the structure inside the floor brush housing 100 , the light-transmitting member 620 has the same shape and size as the corresponding hollow area 611 . Further, the light-transmitting member 620 is fixedly connected to the hollow area 611 .

[0167] In some embodiments, in order to have a better display effect, a light-emitting member 530 such as a display light or a sequin may also be provided on the transmission member 500. When the display light corresponds to the light-transmitting member 620, the moving segment 501 corresponding to the display light may be prompted. It should be noted that in order to ensure the differentiation of the display effect, the non-hollow area 611 of the display component 600 is not light-transmitting.

[0168] Through the above arrangement, the light-transmitting member 620 can improve the visibility and aesthetics of the display, making it easier for the user to identify the current moving segment 501. Different shapes or colors enable the user to quickly identify different moving segments 501. The above arrangement allows the user to intuitively judge the state of the floor brush 10.

[0169] As an optional embodiment, the display component 600 also includes a display screen and a sensor, and the display screen is used to display information. The sensor is located between the floor brush housing 100 and the transmission member 500, and the transmission member is used to sense the positions of different moving segments 501. The display screen can more intuitively display the opening and closing states of the block 300 and the gas plate 400 to enhance the user experience. The display screen is electrically connected to the sensor, and the display screen is used to display the opening and closing states of the block 300 and the gas plate 400 according to the positions of different moving segments 501.

[0170] It is understandable that the display screen can display more complex patterns or texts as needed, and can more intuitively display the opening and closing states of the block 300 and the gas plate 400, thereby shortening the user's judgment time.

[0171] In addition, the sensor can detect the moving distance of different moving sections 501 in real time, and can achieve precise control of the moving distance, thereby improving the accuracy of the moving position of the stopper 300 and the gas plate 400.

[0172] The specific connection between the transmission member 500 and the stopper 300 and the gas plate 400 is described below.

[0173] Reference Figure 6 , Figure 8 as well as Fig.10 As an optional embodiment, a first guide groove 510 and a second guide groove 520 are provided on the transmission member 500, and a first boss 310 and a second boss 410 adapted to the first guide groove 510 and the second guide groove 520 are respectively provided on the stopper 300 and the gas plate 400, and the first boss 310 is movably embedded in the first guide groove 510, and the second boss 410 is movably embedded in the second guide groove 520.

[0174] It is understandable that the cooperation between the boss and the guide groove can ensure the stability of the block 300 and the air plate 400 during movement, reduce shaking and deviation, and thus ensure the reliability of transmission of the transmission member 500 and reduce failures caused by mechanical clearance.

[0175] It should be noted that the first guide groove 510 and the second guide groove 520 are arranged at intervals to avoid interference between the stopper 300 and the gas plate 400 .

[0176] It is understandable that the number of the first guide groove 510 and the second guide groove 520 can be multiple, that is, the transmission member 500 is provided with multiple first guide grooves 510 and second guide grooves 520. Correspondingly, the stopper 300 can be provided with multiple first bosses 310, and the gas plate 400 can be provided with multiple second bosses 410. The multiple first bosses 310 and the multiple second bosses 410 can be respectively arranged in the corresponding first guide grooves 510 and the second guide grooves 520.

[0177] Reference Figure 6 , Figure 8 as well as Fig.10 As an optional embodiment, the first guide groove 510 includes a first guide groove section 511 and a first avoidance groove section 512. One end of the first avoidance groove section 512 is connected to the first guide groove section 511. The first avoidance groove section 512 is arranged along the first direction X1. The extension direction of the first guide groove section 511 intersects with the first direction X1 and the third direction Y3, that is, the extension direction of the first guide groove section 511 intersects with the horizontal direction and the vertical direction, that is, the first guide groove section 511 is arranged obliquely.

[0178] It can be understood that when the first boss 310 moves in the obliquely arranged first guide groove section 511, the block 300 and the transmission member 500 can move synchronously, that is, the transmission member 500 moves in the horizontal direction and the block 300 moves in the vertical direction, thereby realizing that the transmission member 500 drives the block 300 to move.

[0179] When the first protrusion 310 abuts against one end of the first guide slot section 511 away from the first avoidance slot section 512, the stopper 300 blocks the dust collecting port 120, and the dust collecting port 120 is in a closed state. That is, at this time, the stopper 300 is at the end of the first guide slot 510, and the stopper 300 does not move.

[0180] When the first boss 310 is located in the first guide groove 510 and the transmission member 500 moves along the first direction X1, the first boss 310 moves in the first guide groove section 511 toward the first avoidance groove section 512, that is, the block 300 moves vertically upward under the drive of the first boss 310, so that the block 300 opens the dust collecting port 120, and the dust collecting port 120 is in an open state.

[0181] It should be noted that when the first protruding column 310 moves into the first avoiding groove section 512 , since the first avoiding groove section 512 extends in the horizontal direction, the movement of the transmission member 500 cannot drive the stopper 300 to move.

[0182] By moving the first protrusion 310 in the first guide groove section 511 and the first avoidance groove section 512 , the stopper 300 can open or close the dust collecting port 120 , so that the floor brush 10 can adapt to different usage scenarios.

[0183] Reference Figure 6 , Figure 8 as well as Fig.10As an optional embodiment, the second guide groove 520 includes a second guide groove section 521 and a second avoidance groove section 522, one end of the second avoidance groove section 522 is connected to the second guide groove section 521, the second avoidance groove section 522 is arranged along the first direction X1, and the extension direction of the second guide groove section 521 intersects with the first direction X1 and intersects with the third direction Y3, that is, the extension direction of the second guide groove section 521 intersects with the horizontal direction and intersects with the vertical direction, that is, the second guide groove section 521 is arranged obliquely.

[0184] It can be understood that when the second boss 410 moves in the obliquely arranged second guide groove section 521, the air plate 400 and the transmission member 500 can move synchronously, that is, the transmission member 500 moves in the horizontal direction and the air plate 400 moves in the vertical direction, thereby realizing that the transmission member 500 drives the air plate 400 to move.

[0185] When the second convex column 410 is located in the second avoidance groove section 522, the air plate 400 blocks the air inlet 130, and the air inlet 130 is in a closed state. It should be noted that since the second avoidance groove section 522 extends in the horizontal direction, the movement of the transmission member 500 cannot drive the movement of the stopper 300. Therefore, when the second convex column 410 is at any position in the second avoidance groove section 522, the air inlet 130 is in a closed state.

[0186] In the disclosed embodiment, while the second protrusion 410 moves in the second avoidance groove section 522 , the first protrusion 310 can move in the first guide groove section 511 , that is, the air inlet 130 is in a closed state while the dust collection port 120 is in an open state.

[0187] When the second boss 410 is located in the second guide groove section 521 and the transmission member 500 moves along the first direction X1, the second boss 410 moves away from the second avoidance groove section 522 in the second guide groove section 521, that is, the air plate 400 moves vertically downward under the drive of the second boss 410, so that the air plate 400 opens the air inlet 130, and the air inlet 130 is in an open state.

[0188] By moving the second protrusion 410 in the second guide groove section 521 and the second avoidance groove section 522 , the air plate 400 can open or close the air inlet 130 , so that the floor brush 10 can adapt to different usage scenarios.

[0189] Reference Figure 6 , Figure 8 as well as Fig.10As an optional embodiment, when the first protrusion 310 moves from the end of the first guide groove section 511 away from the first avoidance groove section 512 to the connection between the first guide groove section 511 and the first avoidance groove section 512, the stopper 300 is changed from the closed state to the open state. At this time, the displacement of the stopper 300 in the first direction X1 is the first distance, and the first distance is the same as the length of the first avoidance groove section 512. In this way, in the first direction X1, the moving distance of the first protrusion 310 in the first guide groove section 511 is the same as the moving distance in the first avoidance groove section 512. Correspondingly, the distances of the two moving sections 501 corresponding to the transmission member 500 are the same, so as to facilitate the setting of the corresponding display component 600.

[0190] When the second protrusion 410 moves from the end where the second guide groove section 521 is connected to the second avoidance groove section 522 to the end where the second guide groove section 521 is away from the second avoidance groove section 522, the gas plate 400 changes from a closed state to an open state. At this time, the displacement of the gas plate 400 in the first direction X1 is the second distance, and the second distance is the same as the length of the second avoidance groove section 522. In this way, in the first direction X1, the moving distance of the second protrusion 410 in the second guide groove section 521 is the same as the moving distance in the second avoidance groove section 522. Correspondingly, the distances of the two moving sections 501 corresponding to the transmission member 500 are the same, so as to facilitate the setting of the corresponding display component 600.

[0191] Reference Figure 6 , Figure 8 as well as Fig.10 In some embodiments, the angle between the extension direction of the first guide groove section 511 and the extension direction of the first avoidance groove section 512 is A, the length of the first guide groove section 511 is a1, the length of the second avoidance groove section 522 is b2, and the relationship between a1, b2 and A satisfies: a1*cosA=b2. In this way, in the first direction X1, the moving distance of the stopper 300 in the first guide groove section 511 is the same as the moving distance of the transmission member 500 in the second avoidance groove section 522, thereby achieving that the air plate 400 remains stationary when the transmission member 500 drives the stopper 300 to move.

[0192] In some embodiments, the angle between the extension direction of the second guide groove section 521 and the extension direction of the second guide groove section 521 is B, the length of the second guide groove section 521 is b1, the length of the first avoidance groove section 512 is a2, and the relationship between b1, a2 and B satisfies: b1*cosB=a2. In this way, in the first direction X1, the moving distance of the gas plate 400 in the second guide groove section 521 is the same as the moving distance of the transmission member 500 in the first avoidance groove section 512, thereby achieving that the stopper 300 remains stationary when the transmission member 500 drives the gas plate 400 to move.

[0193] Further, according to the above content, when the first protrusion 310 moves in the first avoidance groove section 512, the second protrusion 410 can move in the second guide groove section 521. Therefore, in order to ensure that the first protrusion 310 and the second protrusion 410 can move simultaneously, in the first direction X1, the moving distance of the gas plate 400 in the second guide groove section 521 can be the same as the moving distance of the stopper 300 in the first avoidance groove section 512.

[0194] If a1*cosA=b2 and b1*cosB=a2, when the block moves upward, the air plate does not move, and when the block does not move, the air plate starts to move downward. In this way, the movement of the block and the air plate can be performed alternately, making the structure of the floor brush more compact, which is conducive to the miniaturization of the floor brush and the vacuum cleaner.

[0195] That is, in the first direction X1, the moving distance of the stopper 300 in the first avoidance groove section 512, the moving distance of the stopper 300 in the first guide groove section 511, the moving distance of the gas plate 400 in the second avoidance groove section 522, and the moving distance of the gas plate 400 in the second guide groove section 521 are all the same. In this way, the sizes of the multiple moving sections 501 of the transmission member 500 are all the same.

[0196] Through the above arrangement, the sizes of the multiple moving sections 501 are the same, which can ensure the balance of the transmission member 500 during the movement, reduce shaking, and reduce errors. In addition, the driving member 200 can control the opening and closing of the dust collection port 120 and the air inlet 130 by moving a fixed size, without the need to accurately control the driving member 200, which can reduce the cost of controlling the driving member 200.

[0197] Reference Fig.12 As an optional implementation, the driving member 200 can drive the transmission member 500 in various ways.

[0198] In some embodiments, the driving member 200 includes a driver 210 and a screw rod 220, the driver 210 is disposed on the floor brush housing 100, the screw rod 220 is connected to the driver 210, the transmission member 500 is threadedly connected to the screw rod 220, and the axis of the screw rod 220 is parallel to the first direction X1, so that the rotation of the screw rod 220 can be directly converted into the linear movement of the transmission member 500. Specifically, for each rotation of the screw rod 220, the transmission member 500 moves a distance of a pitch, thereby achieving precise displacement control. The transmission of the screw rod 220 can provide a high-precision and high-stability transmission, and can avoid shaking.

[0199] When the driver 210 drives the screw rod 220 to rotate forward or reverse, the transmission member 500 moves along the axis of the screw rod 220, thereby flexibly controlling the opening and closing of the stopper 300 and the gas plate 400. For example, when the driver 210 rotates the screw rod 220 forward, the transmission member 500 can move along the first direction X1; when the driver 210 rotates the screw rod 220 reversely, the transmission member 500 can move along the second direction X2.

[0200] The above-mentioned bidirectional control capability enables the floor brush 10 to adapt to different cleaning scenarios, and can be achieved with only one driver 210 , which can improve the energy efficiency of the floor brush 10 .

[0201] It should be noted that in the above-mentioned driving member 200, the driver 210 and the screw rod 220 are located on the same extension line, that is, the driver 210 and the screw rod 220 are both located on one side of the transmission member 500 in the horizontal direction, such as the left side or the right side, so that the transmission member 500 can move with the rotation of the screw rod 220.

[0202] In some other embodiments, the driving member 200 includes a driver 210 and a pull rope. The driver 210 is arranged on the floor brush housing 100. Both ends of the pull rope are connected to opposite sides of the transmission member 500. The pull rope is wound around the output shaft of the driving member 200, so that the rotation of the pull rope can be directly converted into a linear movement of the transmission member 500.

[0203] The extension direction of the output shaft of the driving member 200 is perpendicular to the first direction X1, and the pull rope is extended along the first direction X1. The connection mode of the two ends of the pull rope ensures the accuracy of the movement of the transmission member 500. Each time the driver 210 rotates one circle, the transmission member 500 moves a fixed displacement, thereby achieving accurate movement.

[0204] When the driver 210 drives the pull rope to rotate in the forward direction, the pull rope rotates as a whole, and the transmission member 500 moves along the first direction X1; when the driver 210 drives the pull rope to rotate in the reverse direction, the pull rope rotates as a whole, and the transmission member 500 moves along the second direction X2.

[0205] It should be noted that the driver 210 of the driving member 200 connected to the transmission member 500 via a pull rope can be set at different positions on the floor brush 10, and the pull rope can change its direction through a pulley without affecting the transmission of the transmission member 500.

[0206] Through the above arrangement, the connection between the driver 210 and the transmission member 500 is a flexible connection, and the driver 210 and the pull rope are more flexible in spatial arrangement.

[0207] In addition, due to the rigid connection such as the worm and the worm wheel, the worm wheel is arranged on one side of the transmission member 500, and the output shaft of the motor is arranged coaxially with the worm, and the worm wheel and the worm occupy a larger space in the horizontal direction.

[0208] The disclosed embodiment adopts a flexible connection, and the pull rope can reduce the occupation of the internal space of the front end of the floor brush in the horizontal direction, so that the position of the driver 210 is more flexible and does not occupy the internal space of the front end of the floor brush in the horizontal direction, so as to provide more space for the display component.
