[0066] In some embodiments, the cleaning device (100) may have at least a first operating mode and a second operating mode. In some embodiments, the transition between the first operating mode and the second operating mode may be realized by assembling or disassembling the portable vacuum cleaner (3) and the device body (1).

[0067] In some embodiments, the first operating mode may also be referred to as a load-type vacuum cleaner mode. Specifically, in the first operating mode, the portable vacuum cleaner (3) is in communication with the upper part of the device body (1) [the end of the device body (1) away from the floor (or surface to be cleaned)], and the ventilation inlet (310) of the portable vacuum cleaner (3) may be in communication with the dirt storage box (4). When the user activates the portable vacuum cleaner (3), the portable vacuum cleaner (3) can generate suction (e.g., by high-speed rotation of a blade driven by a motor, it can generate negative pressure inside the portable vacuum cleaner), and by the suction force of the portable vacuum cleaner (3), a fluid mixed with gas, dust, and / or liquid passes through the inlet of the floor brush (2) [e.g., suction port (434) of the floor brush (400) shown in FIG. 38] and the fluid channel (e.g., first channel (6)) inside the floor brush (2) and the device body (1), after which the gas, dust, and / or liquid are separated in the first stage (hereinafter referred to as the first separation stage), the dust and / or liquid are stored in the dirt storage box (4), the fluid that has passed through the first separation stage is discharged out of the dirt storage box (4), and then the dust of the portable vacuum cleaner (3) is discharged through the ventilation inlet (310) of the portable vacuum cleaner (3) for the second stage of dust-gas separation. It enters the canister assembly (31). Clean air can be obtained through the second stage of dust-gas separation, and the clean air can be discharged through the ventilation outlet of the portable vacuum cleaner (3).

[0068] In some embodiments, the second operating mode may also be referred to as the portable vacuum cleaner mode. In the second operating mode, the portable vacuum cleaner (3) can be unlocked and separated from the device body (1), and the user can perform cleaning operations using only the portable vacuum cleaner. Specifically, by the suction of the portable vacuum cleaner (3), fluid is introduced into the dust canister assembly (31) from the ventilation inlet (310) of the portable vacuum cleaner (3) for dust-gas separation, and the separated clean air is discharged through the ventilation outlet of the portable vacuum cleaner (3).

[0069] In particular, the fluid included in the present disclosure may be a cleaning air fluid or a fluid introduced together with dirt. The dirt may be one or more of dust, solid dirt (e.g., cigarette butts, paper scraps, rice grains, etc.) and liquid dirt (e.g., orange juice, dirt, liquid egg, etc.).

[0070] In the load-type vacuum cleaner mode, it should be understood that the dirt storage box (4) constitutes a first separation structure. As the airflow containing dirt passes through the dirt storage box (4), the dirt liquid, solid dirt, and dust contained therein can be separated and stored in the dirt storage box (4). Since the dust and gaseous liquid have characteristics such as being small and lightweight, the dust and gaseous liquid are inevitably guided to the dust canister assembly (31) along with the air stream. Therefore, the dust canister assembly (31) constitutes a second separation structure, so that when the air stream flowing into the dust canister assembly (31) contains dirt, the dust canister assembly (31) separates the dust and gas from it, stores the dirt separately in the dust canister assembly (31), and sends the airflow to the ventilation outlet of the portable vacuum cleaner for discharge.

[0071] Based on the above arrangement, the cleaning device (100) provided by the embodiment of the present disclosure has a basic vacuum cleaning function, that is, cleaning dry solid dirt and dust, and at the same time, a function to clean wet waste, fluid-containing materials, or waste mixed with dry dirt, that is, various functions for both dry and wet use. In addition, since the fluid absorbed by the floor brush (2) is separated from the dust in two stages by the dirt storage box (4) and the dust canister assembly (31) of the portable vacuum cleaner (3), relatively clean air can be obtained, thereby reducing air pollution during the cleaning process. In addition, since the portable vacuum cleaner (3) can be detached and used separately, the function of the portable vacuum cleaner can be realized. The cleaning device (100) integrates various functions into one, provides various usage modes, and not only is the structure compact and practical, but storage space required for multiple cleaning devices can also be saved. For example, the portable vacuum cleaner (3) does not need to be mounted on the device body (1) separately after use and placed separately.

[0072] In some embodiments, the cleaning device (100) may further include a cleaning fluid supply assembly, and the cleaning fluid supply assembly may include a cleaning fluid box (50) for storing cleaning fluid, and the cleaning fluid box (50) is removablely installed on the floor brush (2).

[0073] In some embodiments, the cleaning device (100) also has the function of cleaning the floor. The function of cleaning the floor can be realized mainly by a cleaning fluid supply assembly and a floor brush (2).

[0074] In some embodiments, the cleaning fluid supply assembly may further include a spray head and a pump, and the spray head and pump may constitute a water spray system. In some embodiments, the pump may be configured to direct cleaning fluid from the cleaning fluid box (50) to the spray head, and the spray head may serve as the output end of the cleaning fluid supply assembly to spray cleaning fluid onto a floor brush (2) or the floor, thereby cleaning and / or maintaining the floor. In some embodiments, the cleaning fluid may be water or a cleaning agent, conditioner, etc.

[0075] A dirt storage box (4) is positioned on the main body of the device (1), and a cleaning fluid box (50) is positioned on the floor brush (2). By rationally distributing the positions of the two boxes, the main body of the device (1) is not too large in volume and is easy for the user to operate by hand. In some embodiments, by mounting the cleaning fluid box (50) on the floor brush (2), the distance between the cleaning fluid box (50) and the floor brush (2) is shortened, so there is no need to arrange a long cleaning fluid hose between the cleaning fluid box (50) and the floor brush (2), and the spray head is able to spray the cleaning fluid quickly accordingly. Additionally, the cleaning fluid box (50) is provided on the floor brush (2) to increase the weight of the floor brush (2), thereby increasing the pressure applied by the floor brush (2) to the floor and improving the cleaning effect of the floor brush (2). In some embodiments, by providing the dirt storage box (4) on the main body of the device (1) instead of the floor brush (2), the number of items attached to the floor brush (2) is large, which may affect the cleaning range of the floor brush (2). Therefore, based on the above-mentioned optimized structure, the problem of the device body becoming too bulky can be resolved. This not only facilitates operation when held in the user's hand but also offers many improvements, such as easier cleaning even in spaces with limited height.

[0076] In some embodiments, when using the cleaning device (100), it may be necessary to perform tasks such as filling the cleaning fluid box (50) with water, cleaning agent, etc., or cleaning the dirt storage box (4). Accordingly, the cleaning fluid box (50) for the floor brush (2) and the dirt storage box (4) for the device body (1) may be disassembled to perform tasks such as filling the cleaning fluid box (50) with water, cleaning agent, etc., or cleaning the dirt storage box (4).

[0077] A detailed description of how the cleaning fluid supply assembly (e.g., cleaning fluid box, pump, spray head, etc.), floor brush (2), and cleaning device (100) clean the floor can be seen in FIGS. 35 to 50, and the related description may not be repeated in this specification.

[0078] In some embodiments, referring to FIG. 3, the dust canister assembly (31), motor (33), and handle (32) may be arranged sequentially along the first direction (Y) of the portable vacuum cleaner (3). The first direction (Y) of the portable vacuum cleaner (3) may be its longitudinal direction. The dust canister assembly (31), motor (33), and handle (32) may be arranged sequentially along the longitudinal direction of the portable vacuum cleaner (3) from an end closer to the device body (1) to an end farther from the device body (1). For example, the dust canister assembly (31), motor (33), and handle (32) are arranged sequentially from the bottom to the top. In some embodiments, the portable vacuum cleaner (3) has a continuous width from the dust canister assembly (31) to the handle (32). In some embodiments, the portable vacuum cleaner (3) has a continuous width from the dust canister assembly (31) to the handle (32). The portable vacuum cleaner (3) may have a continuous width from the dust canister assembly (31) to the handle (32), and the width corresponding to each position along the first direction (Y) from the dust canister assembly (31) to the handle (32) may be the same or substantially the same. In some embodiments, the portable vacuum cleaner (3) may have a preset width. The fact that the width corresponding to each position along the first direction (Y) from the dust canister assembly (31) to the handle (32) is the same or substantially the same means that there is a difference in the width corresponding to each position of the portable vacuum cleaner (3) along the first direction (Y) from the dust canister assembly (31) to the handle (32), and the preset width is 1%, 2%, 3%, etc. of the preset width.

[0079] In some embodiments, when the portable vacuum cleaner (3) is in an operating state (i.e., a first operating mode or a second operating mode), the user holds the handle (32), the motor (33) is driven by the battery (320) and provides suction (e.g., the motor (33) rotates the blade at high speed to create negative pressure), and under the suction effect, fluid [e.g., fluid sucked into the dirt storage box (4) after the first separation step in the first operating mode or fluid from the external environment in the second operating mode] is introduced into the dust canister assembly (31) through the ventilation inlet (310) for dust-gas separation, and the separated clean air can be discharged from the ventilation outlet of the portable vacuum cleaner (3). By providing a continuous width from the dust canister assembly (31) to the handle (32) in the portable vacuum cleaner (3), the outer surface of the portable vacuum cleaner (3) is relatively smooth and the change in width along the first direction (Y) is relatively small, so that the user can be assured to comfortably hold the handle (32) during operation of the vacuum cleaner. Furthermore, the portable vacuum cleaner (3) is provided to have a continuous width from the dust canister assembly (31) to the handle (32), thereby smoothing the fluid flow inside the portable vacuum cleaner (3) (e.g., from the dust canister assembly (31) to the ventilation outlet); moreover, when the portable vacuum cleaner (3) is applied in a situation parallel to the line of sight, the portable vacuum cleaner (3) causes as little interference as possible to the line of sight, making it easy for the user to place the air ventilation inlet (310) near the object to be cleaned or to install the portable vacuum cleaner (3) on the upper part of the device body (1).

[0080] In some embodiments, when a waste storage box (4) is installed on the device body (1), the combination of the device body (1) and the waste storage box (4) is cylindrical or substantially cylindrical. In some embodiments, a cylindrical combination may mean that the cross-section corresponding to each position of the combination along the length of the device body is a circular cross-section having the same radius. In some embodiments, the cross-section of the combination has a preset radius, and a substantially cylindrical combination means that the difference between the radius of the circular cross-section corresponding to each position and the preset radius is 1%, 2%, 3%, etc. of the preset radius. The cross-section corresponding to each position of the combination along the length direction of the device body is a cross-section of the combination perpendicular to the length direction of the device body.

[0081] In some embodiments, the cross-sectional area of ​​the main part of the assembly [or the middle part of the assembly including the remaining part after removing the upper part of the device body (1) connected to the portable vacuum cleaner, and the lower part of the device body (1) connected to the floor brush (2)] does not substantially change along the longitudinal direction of the device body (1). At the same time, the cross-sectional area of ​​the main part of the portable vacuum cleaner (3) [or the part referred to as the middle part of the portable vacuum cleaner (3) including the part from the dust canister assembly (31) to the motor (33) (e.g., the remaining part after removing the handle (32) and the ventilation inlet (310)) does not substantially change along the longitudinal direction of the device body (1). In some embodiments, the cross-sectional area of ​​the main part of the assembly that does not substantially change along the longitudinal direction of the device body (1) means that each of the first cross-sectional areas corresponding to each position of the main part of the assembly along the length of the device body is the same or substantially the same. The fact that the cross-sectional area of ​​the main part of the portable vacuum cleaner (3) does not change substantially means that the second cross-sectional area corresponding to each position of the main part of the portable vacuum cleaner (3) along the length of the main body of the device (or the length along the first direction (Y)) is the same or substantially the same. The first cross-section is the cross-section of the main part of the assembly perpendicular to the longitudinal direction of the main body of the device, and the second cross-section is the cross-section of the main part of the portable vacuum cleaner perpendicular to the longitudinal direction of the main body of the device. In some embodiments, the first cross-section of the main part of the assembly has a preset first cross-sectional area, and the first cross-sectional area corresponding to each position of the main part of the assembly along the longitudinal direction of the main body of the device may be substantially the same (e.g., the difference between the first cross-sectional area and the first preset cross-sectional area is 1%, 2%, 3%, etc. of the first preset cross-sectional area).Likewise, the second cross-section of the main part of the portable vacuum cleaner (3) has a second preset cross-sectional area, and the second cross-sectional area corresponding to each position of the main part of the portable vacuum cleaner (3) along the longitudinal direction of the device body is substantially the same (e.g., the difference between the second cross-sectional area and the second preset cross-sectional area is 1%, 2%, 3%, etc. of the second preset cross-sectional area).

[0082] It can be seen that the area of ​​the first cross section or the second cross section may be modified (e.g., the area of ​​the cross section corresponding to some location may differ from the area of ​​the cross section corresponding to another location) for the purpose of facilitating the installation of some necessary attachments on the assembly or portable vacuum cleaner (3). In some embodiments, the area of ​​the first cross section or the second cross section may be the area of ​​the outer contour of the cross section perpendicular to the first direction (Y) (or the longitudinal direction of the device body) corresponding to each location of the assembly or portable vacuum cleaner (3) along the longitudinal direction of the device body.

[0083] In some embodiments, the area of ​​the first cross-section and the area of ​​the second cross-section are the same or substantially the same. In some embodiments, the fact that the first cross-sectional area and the second cross-sectional area are substantially the same means that the difference between the area of ​​the first cross-section and the area of ​​the second cross-section is within 1%, 2%, or 3%. By making the first cross-sectional area and the second cross-sectional area the same or substantially the same, the cross-sectional area size of the portable vacuum cleaner (3) can reasonably match the cross-sectional area size of the device body (1) (bond), so that there is no significant change in the cross-sectional size from the device body (1) to the portable vacuum cleaner (3), thereby ensuring that the external contour of the cross-section of the portable vacuum cleaner (3) and the portable vacuum cleaner (3) perpendicular to the first direction (Y) of the device body (1) is aligned or substantially aligned. In addition, the assembly is in the form of a column, so when the portable vacuum cleaner (3) is installed on the device body (1), the entire assembly consisting of the portable vacuum cleaner (3), the device body (1), and the dirt storage box (4) is basically in the form of an elongated column, so when the cleaning device (100) is placed down and used, the device body (1) is easily parallel to the floor, and can be easily accessed even in spaces with limited height, such as the floor of a bed. Overall, the aesthetic appearance of the cleaning device (100) is also improved.

[0084] In some embodiments, referring again to FIG. 3, the fluid channel is located within the device body. In some embodiments, the fluid channel may include a fluid channel (i.e., a first channel (6)) configured within the lower part of the device body (1) (located at the bottom of the dirt storage box (4)) and a fluid channel (not shown) configured within the upper part of the device body (located at the top of the dirt storage box (4)). The fluid channel (i.e., the first channel (6)) in the lower part of the device body (1) is configured to connect the floor brush (2) (suction inlet) to the dirt storage box (4), and the fluid channel in the upper part of the device body (1) may be configured to connect the dirt storage box (4) to a portable vacuum cleaner (3) (dust canister assembly (31) or ventilation inlet (310)). In some embodiments, the fluid channel within the upper part of the device body (1) may be a channel (116) as shown in FIG. 3 or a through hole (1151) as shown in FIG. 7. In the first operating mode, the fluid in the dirt storage box after the first separation step can pass through the fluid channel in the upper part of the device body for the second stage of dust-gas separation and enter the dust canister assembly (31) of the portable vacuum cleaner (3).

[0085] In some embodiments, the cleaning device (100) may further include an attachment member that is removablely connected to the portable vacuum cleaner (3). In some embodiments, the attachment member may include one or more of a mite removal brush, a flat brush, a bristle brush, a pet brush, and a hose. In some embodiments, the attachment member may be divided into a storage member and a brush head member. The storage member and the brush head member may be configured to be connected to the portable vacuum cleaner (3) when the portable vacuum cleaner (3) is used individually (e.g., in a second operating mode). It may be understood that in some embodiments, the storage member may include a hose, a long storage container, etc., and the brush head member may include a mite removal brush, a flat brush, a bristle brush, a pet brush, etc. When using the portable vacuum cleaner (3) individually, the portable vacuum cleaner can be used directly to complete the portable vacuum cleaning task, and brush head components such as a mite removal brush, a flat brush, a bristle brush, a pet brush can be connected, and storage components such as a hose and a long storage container can be adapted between the portable vacuum cleaner (3) and the brush head components to fulfill cleaning requirements in various situations.

[0086] FIG. 4 is a schematic diagram illustrating the structure of a vacuum cleaner according to some embodiments of the present disclosure.

[0087] In some embodiments, the cleaning device (100) may have a structural form as shown in FIG. 4. In FIG. 4, the second cross-sectional area of ​​the main part of the portable vacuum cleaner (3) may differ from the cross-sectional area of ​​the combination of the device body (1) and the dirt storage box (4). For example, the area of ​​the second cross-section may be smaller than the area of ​​the first cross-section. In some embodiments, the cleaning device (100) may not include the portable vacuum cleaner (3). For example, the part of the genuine portable vacuum cleaner (3) in FIG. 4 may be a part of the device body (1) that extends upward, and the cross-sectional area of ​​the extension perpendicular to the longitudinal direction of the device body (1) is smaller than the area of ​​the first cross-section. In some embodiments, as shown in FIG. 4, a motor (34) may be provided inside the device body (1) and on top of the dirt storage box (4), and the motor (34) may provide suction power to the cleaning device (100) to absorb fluid from the floor (or surface to be cleaned).

[0088] FIG. 5 is a right side view illustrating a cleaning device according to some embodiment of the present disclosure. FIG. 6 is a schematic diagram illustrating the disassembled structure of the cleaning device illustrated in FIG. 5. FIG. 7 is a schematic diagram illustrating a part of the structure of the cleaning device illustrated in FIG. 5.

[0089] In some embodiments, the cleaning device (100) according to some embodiments of the present disclosure may have a structural form as shown in FIGS. 5 to 7. The difference between the structure shown in FIGS. 5 to 7 and the structure shown in FIGS. 1 to 3 or FIG. 4 includes the fact that the position where the portable vacuum cleaner (3) is placed is different. For example, the portable vacuum cleaner (3) shown in FIGS. 1 to 3 or FIG. 4 is placed at an end away from the bottom of the device body (1), and the portable vacuum cleaner shown in FIGS. 5 to 7 is placed on the side of the device body (1) (e.g., the front side of the device body (1)) that is the same as the dirt storage box (4).

[0090] Additionally, as illustrated in FIGS. 5 and 6, the device body (1) of the cleaning device (100) may include a rod (11) formed integrally in the shape of a rod. A floor brush connecting end (111) may be provided at the lower end of the rod (11) to pivotably connect to a floor brush (2) (e.g., the connecting part (420) of the floor brush (400) illustrated in FIG. 35), and a handle end (112) convenient for a user to grip is provided at the upper end of the rod (11).

[0091] A portable vacuum cleaner (3) and a dirt storage box (4) (e.g., dirt storage box (4, 300)) are installed on the front side of the device body (1) so as to be detachable and attachable, and the portable vacuum cleaner (3) is provided on the upper part of the dirt storage box (4); the device body (1) is composed of a first channel (6) that communicates the floor brush (2) and the dirt storage box (4). The operating principle of the cleaning device (100) shown in FIGS. 5 to 7 is similar to that shown in FIGS. 1 to 3, and a related description thereof can be referred to in FIGS. 1 to 3 and the related description thereof, which will not be repeated here.

[0092] In some embodiments, as shown in FIG. 7, the device body (1) may include a fixed sheet (115), the fixed sheet (115) may be partially convex with respect to the rod (11) of the device body (1), and a portable vacuum cleaner (3) is detachably connected to the device body (1) through the fixed sheet (115).

[0093] In some embodiments, the fixed sheet (115) is provided with a through hole (1151). An end of a dust canister assembly (31) having a ventilation inlet (310) and a through hole (1151) can be fitted and connected. The expression “fit and connected” refers to the shape of the end of the dust canister assembly (31) having the ventilation inlet (310) being fitted to the shape of the through hole (1151), so that the dust canister assembly (31) forms a sealing channel with the through hole (1151) and can process fluid discharged from the dirt storage box (4). Additionally, for individual use of the portable vacuum cleaner (3), the user can directly detach the portable vacuum cleaner (3) that is inserted into the fixed sheet (115). Accordingly, fluid sealing and locking stability between the portable vacuum cleaner (3) and the dirt storage box (4) can be balanced. As an exemplary example, as shown in FIG. 6, the portable vacuum cleaner (3) and the dirt storage box (4) can be flexibly connected by being sealed at the top and bottom of the through hole (1151), respectively. The fluid separated in the first separation step flows into the ventilation inlet (310) of the portable vacuum cleaner (3) through the through hole (1151).

[0094] In some embodiments, the dirt storage box (4) may be located at the end of the fixed sheet (115) away from the portable vacuum cleaner (3), and the dirt storage box (4) may be detachably connected to the device body (1) through the fixed sheet (115). For example, the end of the dirt storage box (4) away from the floor brush (2) is fitted into the end of the fixed sheet (115) that is pulled back from the portable vacuum cleaner (3) to realize a detachable connection between the dirt storage box (4) and the fixed sheet (115).

[0095] In some embodiments, to increase the reliability of the connection between the portable vacuum cleaner (3), the dirt storage box (4), and the device body (1), the device body (1) may include a first locking mechanism (113). The first locking mechanism (113) is configured to lock the portable vacuum cleaner (3) to the device body (1). In some embodiments, the device body (1) may include a second locking mechanism (114). The second locking mechanism (114) is configured to lock the dirt storage box (4) to the device body. Both the portable vacuum cleaner (3) and the dirt storage box (4) may be individually detachable from the device body (1) by arranging the first locking mechanism (113) and the second locking mechanism (114). In some embodiments, the first locking structure (113) or the second locking structure (114) may be any one of a locking structure, a clamping structure, a magnetic suction structure, or a bonding structure.

[0096] As illustrated in FIG. 3, to increase the installation stability of the waste storage box (4), the device body (1) may further include a waste storage box support sheet (5). The waste storage box support sheet (5) may support the waste storage box (4) from the bottom or side of the waste storage box (4) so ​​that the waste storage box (4) can be stably connected to the device body (1). In some embodiments, the waste storage box support sheet (5) may be placed at the rear of the device body (1). The rear side of the device body (1) may be the side that the device body (1) faces the user when the user operates the cleaning device (100) (e.g., the right side of the device body (1) illustrated in FIG. 3).

[0097] In some embodiments, the waste storage box support sheet (5) may be arranged in a groove shape. The groove is formed at the rear of the device body (1), and at least most of the waste storage box (4) is accommodated inside the groove. In some embodiments, more than half of the volume of the waste storage box (4) is placed in the groove, so that the structure of the device body can be made relatively smooth and rounded after the waste storage box (4) is installed, making it difficult to hit or collide with other objects.

[0098] In some embodiments, when the locking of the waste storage box (4) is released by the second locking structure (114), one end of the waste storage box support sheet (4) may automatically move away from the device body (1) and form a specific angle with the device body (1) so that the user can easily take out the waste storage box (4). The specific angle may not be greater than 45°. For example, the specific angle may be 15°, 20°, 30°, 45°, etc. It should be noted that the angle may be greater than 45° (e.g., 50°, 60°). The specific value of the angle may be selected according to the actual situation, and it is sufficient if the user can take out the waste storage box (7) and recognize that the liquid inside the waste storage box (7) can be prevented from overflowing.

[0099] In some embodiments, the waste storage box support sheet (5) is pivoted on the device body (1), and a plug member in the form of a plate or block is configured at one end of the waste storage box support sheet away from the pivoted portion. An elastic member is provided between the waste storage box support sheet (4) and the device body (1), and this elastic member can bounce the waste storage box support sheet (5) against the device body (1) so that the plug member can automatically detach from the device body (1). For example, in some embodiments illustrated in FIGS. 6 and 7, one end of the waste storage box (4) is fitted and connected to a fixed sheet (115), and the other end of the waste storage box (4) is connected to the waste storage box support sheet (5). At this time, a portion of the side wall of the waste storage box (4) is attached to the device body (1), and the elastic member is compressed by the action of the waste storage box (4) and the plug member. When the user separates the waste storage box (4) from the fixed seat (115), the plug member moves away from the device body (1) by the elastic force of the elastic member, and at the same time, the plug member drives the waste storage box (4) away from the device body (1). In some embodiments, the spring member may include one or more of a spring, a leaf spring, a bellows, etc. The waste storage box (4) is provided with a plug-in member (41) that can be coupled with the plug member, so that when the plug member is rotated, the waste storage box (4) can be connected to the plug member through the plug-in member (41). For example, when the plug member moves away from the device body (1) by the action of the elastic member, the waste storage box (4) moves away from the device body (1) together with the plug member, and the process of moving the waste storage box (4) away from the device body (1) can be considered as the automatic deployment of the waste storage box (4). In some embodiments, the same effect of automatic unfolding of the waste storage box (4) can be achieved by switching the positions of the plug member and the plug-in member.

[0100] When there is liquid in the waste storage box (4), if the automatic unfolding angle is too large, the liquid is prone to splashing or overflowing; therefore, the automatic unfolding angle of the waste storage box (4) relative to the device body (1) may be 45° or less, and a limiting plate may be installed on the device body (1) to specifically limit the maximum rotational amplitude of the second locking structure (114). In addition, to avoid the liquid in the waste storage box (4) shaking violently due to the automatic unfolding being too fast, in some embodiments, a rotary damper is provided on the pivoting portion of the waste storage box support sheet (5).

[0101] By providing a fixed sheet (115) that is convex with respect to the device body (1) to the device body (1), the center of gravity and most of the weight of the portable vacuum cleaner (3) are supported on the fixed sheet (115) rather than the device body (1). Additionally, a first locking mechanism (113) is provided to the device body (1), so that the portable vacuum cleaner (3) can be stably fixed by the cooperation of the fixed sheet (115) and the first locking structure (113). Furthermore, the contact area between the device body (1) and the dirt storage box (4) may be reduced by providing a dirt storage box support sheet (5), a fixed sheet (115), and a second locking structure (114) to the device body (1).

[0102] The vacuum cleaner provided in the embodiment of the present disclosure can realize the fixing of the portable vacuum cleaner (3) or the dirt storage box (4) through the structure of the fixed sheet (115), the locking structure [e.g., the first locking structure (113), the second locking structure (114)], the dirt storage box support sheet (5), etc., thereby minimizing the requirement for the support area of ​​the device body (1), so that the rod body (11) can be configured in an elongated rod shape, and thereby the overall weight of the device body (1) can be reduced. For example, the overall weight of the device body can be reduced by more than 70%, and the appearance of the entire device is simple and neat.

[0103] Additionally, it can be understood that the cross-sectional area along the longitudinal direction of the elongated rod body (11) does not change substantially, and that the cross-sectional area (e.g., the cross-sectional area perpendicular to the longitudinal direction of the rod body (11)) must undergo partial change to facilitate the installation of necessary attachments such as locking structures. Here, the lack of change means that most of the cross-sectional area of ​​the rod body (11) along the longitudinal direction (the Y direction shown in FIG. 3) does not change significantly. The cross-sectional area of ​​the rod body (11) may have a minimum value and a maximum value, and even the maximum cross-sectional area must be smaller than any one of the average cross-sectional area of ​​the fixed sheet (115), the cross-sectional area of ​​the portable vacuum cleaner (3), or the average cross-sectional area of ​​the dirt storage box (4). The average cross-sectional area of ​​the fixed sheet (115) is the average of the cross-sectional areas of the secondary fixed sheet (115). The average cross-sectional area of ​​the portable vacuum cleaner (3) is the average cross-sectional area of ​​the fixed sheet (115) at different locations along the longitudinal direction of the rod body (11). The average cross-sectional area of ​​the portable vacuum cleaner (3) is the average cross-sectional area of ​​the portable vacuum cleaner (3) at different locations along the longitudinal direction of the rod body (11). In some embodiments, the maximum cross-sectional area of ​​the rod body (11) may be less than half of the three cross-sectional areas to ensure the lightweighting of the rod body (11). In some embodiments, the ratio of the size (U1) of the rod body (11) along the front-rear direction (the x-direction may be the width direction shown in FIG. 7) to the scale (V1) of the device body (1) along the length direction (the Y-direction shown in FIG. 7) may be in the range of 0.02 to 0.06. The size (U1) of the rod body (11) along the width direction may be 43 mm to 49 mm, and the size (V1) of the rod body (11) along the length direction may be 1000 mm to 1200 mm. With this arrangement, the device body is made lighter overall, making it convenient for the user to hold and use, and the overall size and weight of the cleaning device (100) can be optimized.

[0104] In some embodiments, the fixed sheet may be in the shape of a roughly circular ring, and the ratio of the maximum size of the fixed sheet along the width direction (e.g., U2 shown in FIG. 7) to the size (U1) of the rod body (11) along the width direction is in the range of 1.8 to 3, which allows usability to be ensured while designing the total width of the fixed sheet and the rod body (11) to be as small as possible, and facilitates the control of the rod body (11) to push the floor brush (2) deep into the bed floor. When protruding along the length direction of the device body (1), the ratio of the protruding area of ​​the fixed sheet (115) to the protruding area of ​​the rod body (11) is in the range of 6.5 to 9. Here, the protruding area refers to the area enclosed by the outer edge of the cross-sectional area. Specifically, the protruding area of ​​the fixed sheet (115) is in the range of 55 cm² to 80 cm².

[0105] In some embodiments, as illustrated in FIGS. 1 to 4, the dirt storage box (4) may be provided on the rear side of the device body (1) (e.g., the side facing the user when operating the cleaning device (100)). For example, the dirt storage box (4) may be provided on the dirt storage box support sheet (5) (e.g., a groove). In some embodiments, as illustrated in FIGS. 5 to 7, the dirt storage box (4) may be provided on the front side of the device body (1). It should be noted that when the present disclosure relates to a front-rear orientation such as "front side", "rear side," etc., "front side" may mean the side facing away from the user when operating the cleaning device (100) without special description (e.g., the left side in FIG. 4), and "rear side" may be the side facing the user (e.g., the right side in FIG. 4). For example, as shown in Fig. 4, the direction of arrow A is "backward", and the opposite direction of arrow A is "forward".

[0106] It should be understood that the structural diagrams of the cleaning device provided in FIGS. 1 through 7 are for illustrative purposes only and are not intended to limit the scope of the present disclosure. Those skilled in the art may make various modifications and variations under the teachings of the present disclosure. Such modifications and variations fall within the scope of protection of the present disclosure. In some embodiments, the number of elements depicted in the drawings may be adjusted according to actual circumstances. In some embodiments, one or more of the elements depicted in FIGS. 1 through 7 may be omitted, or one or more of the other elements may be added or deleted. In some embodiments, an element may be replaced with another original element capable of performing a similar function. In some embodiments, an element may be divided into a plurality of sub-elements, or a plurality of elements may be combined into a single element.

[0107] Hereinafter, a waste storage box according to some embodiments of the present disclosure will be described in detail with reference to the attached drawings.

[0108] FIG. 8 is a schematic diagram illustrating the internal structure of a waste storage box according to some embodiments of the present disclosure. FIG. 9 is a schematic diagram illustrating the overall structure of a waste storage box according to some embodiments of the present disclosure.

[0109] In some embodiments, the dirt storage box (4) of the cleaning device (100) shown in FIGS. 1 to 7 may specifically be the dirt storage box (4) shown in FIGS. 8 and 9.

[0110] In conjunction with the waste storage box illustrated in FIGS. 8 and 9, the waste storage box (4) may include a box body (201). The box body (201) is provided with a second channel (202) connected to a floor brush. For example, the lower end of the second channel (202) (e.g., the end near the floor) may be connected to the upper end of the first channel (6) illustrated in FIG. 2 to enable communication between the second channel (202) and the floor brush (e.g., the floor brush (2) illustrated in FIG. 2). In some embodiments, the second channel (202) is also referred to as a waste channel. In some embodiments, a partition plate (203) may be provided inside the box body (201), and the partition plate (203) may divide the internal space of the box body (201) into an upper space (204) and a lower space (205). The upper space (204) is close to the portable vacuum cleaner (3), and the lower space (205) is close to the floor brush. The second channel (202) may extend upward from the lower space (205) through the partition plate (203) to the upper space (204). In some embodiments, the partition plate (203) may be provided with a first hole group (231) and a backflow prevention structure (230), and the backflow prevention structure (230) may be configured to allow dirt from the upper space (204) to flow into the lower space (205) through the first hole group (231) and to prevent dirt from the lower space (205) from flowing into the upper space (204) through the first hole group (231). Additionally, dirt introduced into the upper space (204) of the box body (201) from the second channel (202) can be introduced into the lower space (205) and stored through at least the first hole group (231), and the backflow prevention structure (230) can prevent dirt from the lower space (205) from flowing back into the upper space (204) through the backflow prevention structure (230).

[0111] In some embodiments, as illustrated in FIG. 8, the second channel (202) and the box body (201) may be an integral structure. For example, the second channel (202) may be formed integrally by an injection molding process, which is simple and convenient to manufacture. In some embodiments, the second channel (202) and the box body (201) may also be a split structure, so that the second channel (202) can be removed from the box body (201) when necessary to thoroughly clean the second channel (202) and / or the box body (201). In some embodiments, where the second channel (202) and the box body (201) are a split structure, the two may be connected by screws or sealed together.

[0112] In some embodiments, as illustrated with reference to FIGS. 1 to 7 and FIG. 8, in the case of a cleaning device (100) equipped with a dirt storage box (4), when the device body (1) (or dirt storage box (4)) is maintained in a substantially upright position (e.g., when the angle of the device body (1) with respect to the horizontal plane is 90 degrees or more or 60 degrees or more, hereinafter referred to as “upright”), dirt is sucked in and sent to a second channel (202), and then flows from the second channel (202) to an upper space (204), and then flows from the first hole group (231) to a lower space (205) through a backflow prevention structure (230) and is stored in the lower space (205). In some embodiments, the second channel (202) may be in communication with the first channel (6), and when the cleaning device (100) is in operation, dirt sucked by the floor brush (2) may flow sequentially into the second channel (202) from the first channel (6). When the device body (1) (or dirt storage box (4)) is significantly tilted (e.g., at an angle of 30 degrees or less with respect to the horizontal plane or even about 2 degrees with respect to the horizontal plane, hereinafter referred to as ‘flattened’ or ‘laying down’), the backflow prevention structure (230) prevents dirt in the lower space (205) from flowing back into the upper space (205) through the backflow prevention structure (230). The backflow prevention structure (230) prevents dirt in the lower space (205) from flowing back into the upper space (204) through the backflow prevention structure, thereby preventing dirt from flowing into the motor (motor (33) and / or motor (34)). The motor does not stop, and the cleaning device (100) can still perform cleaning normally. As a result, the cleaning device equipped with the dirt storage box (4) can be used not only in an upright position, but also with the device body (1) tilted significantly, or in a flat or lying position, making it very easy for the user to use.

[0113] In some embodiments, in the waste storage box (4) illustrated in FIGS. 8 and 9, an opening is formed at one end of the box body (201) (e.g., the end near the portable vacuum cleaner (3)) to allow waste to be discharged. A cover body (216) may be provided at the opening, and a gas outlet channel (218) may be provided in the cover body (216). The inlet (219) of the gas outlet channel (218) may be in communication with the upper space (204). At the outlet (221) of the gas outlet channel (218), a motor (33 or motor (34)) or a pumping device (e.g., a suction pump) in communication with the motor is provided to pump gas inside the box body (201), thereby sucking waste into the box body (201) through the second channel (202). In some embodiments, a filter member (not shown in the drawings) is provided at the outlet (221) of the gas outlet channel (218). The filter element may be configured to filter fine solids (i.e., solid debris) accompanying the gas to prevent the motor from clogging with debris. In some embodiments, the filter element may be HEPA to improve filtration. In some embodiments, the outlet (221) of the gas outlet channel (218) may be connected to a portable vacuum cleaner (3) so that the gas obtained after separation within the cavity (201) (e.g., first stage of dust-gas separation) may flow through the outlet (221) of the gas outlet channel (218) into the dust canister assembly (31) of the portable vacuum cleaner (3) for the second stage of dust-gas separation, thereby obtaining clean gas discharged from the ventilation outlet of the portable vacuum cleaner (3).

[0114] In some embodiments, the cyclone separation structure (260) may be provided within the gas outlet channel (218). When gas flows through the cyclone separation structure (260), the cyclone separation structure (260) separates a portion of the solid waste carried by the gas (e.g., a first separation step), and the remaining solid waste is filtered by a filter member. In some embodiments, the cyclone separation structure (260) may be formed integrally with the cover body (216), and the cyclone separation structure (260) may be easily cleaned by separating the cover body (216). Additionally, by providing the cyclone separation structure (260), the load on the filter member is reduced, the lifespan of the filter member is improved, the frequency of maintenance or replacement of the filter member is reduced, and the user's use of the cleaning device (100) is made easier.

[0115] FIG. 10 is a schematic diagram illustrating the structure of a bulkhead plate according to some embodiments of the present disclosure. As illustrated in FIG. 10, a first hole group (231) is provided in the bulkhead plate (203). A backflow prevention structure (230) includes a backflow prevention valve (232) corresponding to the first hole group (231) installed in the bulkhead plate (203). The backflow prevention structure (230) is positioned in the lower space (205) and communicates with the upper space (204) through the first hole group (231). Alternatively, a first portion (206) of the edge of the bulkhead plate (203) may be in sealing contact with the side wall of the box body (201). In some embodiments, a sealing ring is provided between the edge of the bulkhead plate (203) and the side wall of the box body (201) to realize sealing contact between the bulkhead plate (203) and the box body (201). Due to this structure, the backflow prevention valve (232) can prevent dirt from the lower space (205) from flowing into the upper space (204) through the backflow prevention valve (232) when the device body (1) is placed parallel to the ground. Additionally, due to the seal between the edge of the partition plate (203) and the side wall of the box body (201), dirt from the lower space (205) can be prevented from flowing into the upper space (204) through the gap between the edge of the partition plate (203) and the box body (201). Accordingly, it is possible to prevent dirt from flowing back into the upper space (204) and being sucked into the motor, and the cleaning device (100) can be used by placing it parallel to the ground. Additionally, when cleaning the waste storage box (4), the partition plate (203) can be removed from the box body (201), and solid waste in the waste can be filtered by the first hole group (231). That is, waste is stored in the box body (201), and solid waste is loaded onto the partition plate (203), thereby realizing the separation of solid waste from the waste.Afterwards, solid waste is separated and emptied into a trash can, and waste is emptied into a discharge device such as a toilet or sink, thereby effectively preventing the discharge device such as a toilet or sink from becoming clogged. In addition, the structure of the partition plate (203) having the first hole group (231) and the structure of the backflow prevention valve (232) are simple, the manufacturing process is simple, and the cost is low, making it easy to use in the cleaning device (100).

[0116] In some embodiments, the first hole group (231) may include one or more first through holes. In some embodiments, to improve the efficiency of waste flowing from the upper space (204) to the lower space (205), the number of first through holes in the first hole group (231) may be in the range of 50 to 200. In some embodiments, to ensure the structural strength of the bulkhead plate (203), the number of first through holes in the first hole group (231) may be 70 to 150. In some embodiments, the number of first through holes in the first hole group (231) may be in the range of 80 to 120.

[0117] In some embodiments, the first through hole may have a regular or irregular shape, such as a bar-shaped hole or a circular hole. In some embodiments, the first through hole is a bar-shaped hole, and the length and width of the bar-shaped hole are relatively large so that the efficiency of the dirt passing through the first hole group (231) can be secured, and also effectively prevent solid waste from passing through the first through hole, thereby allowing the partition plate (203) to have a better filtration effect. In some embodiments, when the first through hole is a bar-shaped hole, the length-to-width ratio of the bar-shaped hole may be within the range of 0.5 to 2 so that the partition plate (203) has a relatively large filtration effect and prevents solid waste from passing through the first hole group (231). In some embodiments, the length-to-width ratio of the bar-shaped hole may be within the range of 0.7 to 1.5. In some embodiments, the length-to-width ratio of the bar-shaped hole may be 0.8 to 1.2.

[0118] In some embodiments, the area of ​​the first through hole in the first hole group (231) may be 80 mm² to 100 mm², thereby improving the efficiency of dirt passing through the first hole group (231), and also better blocking solid waste and providing a better filtration effect. In some embodiments, the area of ​​the first through hole in the first hole group (231) may be 85 mm² to 100 mm². The area of ​​the first through hole in the first hole group (231) may be 90 mm² to 100 mm². In some embodiments, the area of ​​the first through hole in the first hole group (231) may be 98 mm², thereby improving the efficiency of dirt passing through the first hole group (231) and blocking solid waste.

[0119] Since the first hole group (231) is provided in the bulkhead plate (203), the ratio of the area of ​​the first hole group (231) in the bulkhead plate (203) (i.e., the ratio of the total area of ​​the first through hole in the first hole group (231) to the area of ​​the bulkhead plate (203)) is related to the structural strength of the bulkhead plate (203). This is to ensure that the bulkhead plate (203) has relatively better structural strength and has a higher passage efficiency for the channel of dirt to pass through the first hole group (231). In some embodiments, the ratio of the area of ​​the first hole group (231) on the bulkhead plate (203) may be 0.1 to 0.5. In some embodiments, the ratio of the area of ​​the first hole group (231) on the bulkhead plate (203) may be 0.1 to 0.4. In some embodiments, the area ratio of the first hole group (231) on the bulkhead plate (203) may be 0.2 to 0.3.

[0120] In some embodiments, the partition plate (203) is detachably installed inside the box body (201) so that the partition plate (203) can be easily removed from the box body (201). In some embodiments, as shown in FIG. 10, the partition plate (203) is provided with a handle (307) and a handle (207), and the handle (207) extends toward the opening of the box body (201) (i.e., the end where the cover body (216) is provided). Thus, when cleaning the waste storage box (4), the user can easily remove the partition plate (203) from the box body (201) by lifting the handle (207). Solid waste contained in the partition plate (203) can also be removed from the box body (201), thereby separating the solid waste from the waste. In some embodiments, the partition plate (203) may be directly connected to the cover body (216). In this way, when removing the cover body (216), the partition plate (203) can also be removed at the same time. This prevents a situation where the waste and solid waste are mixed again by forgetting to remove the partition plate (203) when disposing of the waste in the waste storage box (4).

[0121] In some embodiments, the bulkhead plate (203) may include a cambered plate. In some embodiments, the bulkhead plate (203) may be a cambered plate protruding toward the lower space, and the first hole group (231) may be offset from the lowest point of the bulkhead plate (203). The lowest point of the bulkhead plate (203) may be a location on the upper or lower surface of the bulkhead plate (203) at a minimum distance from the floor brush (2). The first hole group (231) offset from the lowest point of the bulkhead plate (203) may be understood as the distance between the lowest point of the bulkhead plate (203) and the location of the first hole group (231) along the radial direction of the bulkhead plate (203). By providing the bulkhead plate (203) as a protruding chamfered plate, solid waste can be concentrated at the lowest point of the bulkhead plate (203), and accordingly, the possibility of the first hole group (231) being clogged by solid waste is reduced, and the user can use the cleaning device (100) more easily.

[0122] In some embodiments, continuing with reference to FIG. 10, a second hole group (210) is also provided in the partition plate (203), and the second hole group (210) freely connects the upper space (204) and the lower space (205). When in use, dirt is introduced into the lower space (205) through the first hole group (231), and air in the lower space (205) is introduced into the upper space (204) through the second hole group (210) and pumped by a motor (e.g., motor (34)), thereby increasing the pressure difference between the upper space (204) and the lower space (205), so that dirt can flow smoothly from the upper space (204) to the lower space (205). In some embodiments, some of the dirt in the upper space (204) may flow from the second hole group (210) to the lower space (205). Accordingly, the second hole group (210) can filter solid waste from the filth. In some embodiments, the second hole group (210) may be offset from the first hole group (231) around the perimeter of the partition plate (203). In some embodiments, the second hole group (210) may mean that there is a gap between the second hole group (210) and the first hole group (231) around the perimeter of the partition plate (203) where the second hole group (210) is offset from the first hole group (231) around the perimeter of the partition plate. The circumferential direction of the partition plate (203) may mean a direction along the edge of the partition plate (203). Accordingly, when the cleaning device (100) is installed and used parallel to the ground, the backflow prevention valve (232) is closed so that the level of dirt in the lower space (205) can be lower than that of the second hole group (210), so that the dirt in the lower space (205) can also not flow into the upper space (204) through the second hole group (210). In some embodiments, the first hole group (231) may be radially opposite to the second hole group (210).In some embodiments, the first hole group (231) being radially opposite to the second hole group (210) may mean that the first hole group (231) and the second hole group (210) are symmetrically centered with respect to the geometric center of the partition plate (203) along the radial direction of the partition plate (203). This ensures that the distance between the first hole group (231) and the second hole group (210) along the circumference of the partition plate (203) is relatively large, so that even though there is a relatively large amount of dirt in the lower space (205), the level of dirt is not higher than that of the second hole group (210), and that dirt in the lower space (205) is not introduced into the upper space (204) through the second hole group (210), thereby making it easier for the user to use the cleaning device (100). In some embodiments, the second hole group (210) may include one or more second through holes. In order to increase the efficiency of the dirt passing through the second hole group (210), effectively block solid waste, and provide excellent filtration, in some embodiments, the area of ​​the second through hole in the second hole group (210) may be 350 mm² to 400 mm². In some embodiments, the area of ​​the second through hole in the second hole group (210) may be 360 ​​mm² to 390 mm². In some embodiments, the area of ​​the second through hole in the second hole group (210) may be 360 ​​mm² to 390 mm². In some embodiments, the area of ​​one or more second through holes in the second hole group (210) may be 370 mm² to 380 mm². In some embodiments, the area of ​​the second through hole in the second hole group (210) may be 376 mm², which can increase the efficiency of the dirt passing through the second hole group (210) and block solid waste.

[0123] In order to ensure that the structural strength of the bulkhead plate (203) is good and the efficiency of dirt passing through the second hole group (210) is high, in some embodiments, the area ratio of the second hole group (210) in the bulkhead plate (203) (e.g., the ratio of the total area of ​​the second through hole of the second hole group (210) to the area of ​​the bulkhead plate (203)) may be 0.01 to 0.2. In some embodiments, the area ratio of the second hole group (210) in the bulkhead plate (203) may be 0.02 to 0.1. In some embodiments, the area ratio of the second hole group (210) in the bulkhead plate (203) may be 0.05 to 0.08.

[0124] In some embodiments, the second through holes of the second hole group (210) may have the same or different shape, number, etc. as the first through holes of the first hole group (231). In some embodiments, additional descriptions regarding the number and shape of the second through holes of the second hole group (210) can be found in the relevant descriptions regarding the number and shape of the first through holes of the first hole group (231) and may not be repeated here.

[0125] In some embodiments, when the cleaning device (100) is used tilted or laid flat (lying parallel to the ground), to prevent dirt from flowing from the lower space (205) into the upper space (204), only the second hole group (210) is provided in the partition plate (203) without the first hole group, and in this case, it is sufficient to arrange the cleaning device (100) so that it does not tilt toward the direction of the second hole group (210). For example, if the second hole group (210) is provided in the partition plate (203) near the front side of the box body (201), the cleaning device (100) may tilt toward the rear side when in use. In some embodiments, if the partition plate (203) is provided as a chamfered plate, the second hole group (210) may be offset from the lowest point of the partition plate (203). The possibility of the second hole group (210) becoming clogged with solid waste can be reduced, making it easier for the user to use the cleaning device (100).

[0126] In some embodiments, continuing with reference to FIG. 10, a baffle wall (211) may be provided along the circumferential upright of the partition plate (203), and the baffle wall (211) may extend into at least the upper space (204). The baffle wall (211) may prevent solid waste from falling from the edge of the partition plate (203) into the box body (201) when the partition plate (203) is lifted from the box body (201). In some embodiments, the baffle wall (211) may be provided with a leaching hole, which not only prevents the falling of solid waste but also improves the effect of separating solid waste and dirt by discharging dirt remaining on the partition plate (203) into the box body (201) through the leaching hole. In some embodiments, after vertically installing a frame (212) along the circumferential direction of the bulkhead plate (203), a strainer (213) may be provided in the frame (212), and the strainer (213) may act as a leaching hole to form the baffle wall (211) having the leaching hole. In some embodiments, where the baffle wall (211) is provided in the bulkhead plate (203), the handle (207) may be connected to or integrally molded with the baffle wall (211) (e.g., the handle (207) may be part of an upward extension of the frame (212), which may not be repeated here.

[0127] In some embodiments, continuing to refer to FIG. 9 and FIG. 10, the partition plate (203) is further provided with an installation hole (214). The installation hole (214) is offset from the first hole group (231) and the second hole group (210). For example, there is a gap along the radial direction of the partition plate (203) between the installation hole (214) and the first hole group (231), and there is a gap along the radial direction of the partition plate between the installation hole (214) and the second hole group (210). The second channel (202) may be a pipe structure, and the second channel (202) may extend upward from the lower space (205) to the upper space (204) through the installation hole (214). This allows the partition plate (203) to be easily fitted into the box body (201). In some embodiments, the installation hole (214) and the second channel (202) are in sealing contact (e.g., a sealing ring may be provided between the edge of the installation hole (214) and the second channel (202)), thereby preventing the existence of a gap between the edge of the installation hole (214) and the second channel (202) when the cleaning device (100) is placed flat, thus preventing dirt from entering from the lower space (205) to the upper space (204) through the gap between the edge of the installation hole (214) and the second channel (202).

[0128] In some embodiments, the second channel (202) may be provided with a waste opening positioned on the side wall of the box body (201) to communicate with the upper space (204). The waste opening may be understood as an opening through which waste enters the box body (201) [upper space (204)] along the second channel (202). In an embodiment not illustrated, a top wall is provided on the top of the box body (201), and an opening for disposing of waste is provided in the top wall, and a cover body (216) may cover the opening. In this case, the waste opening of the second channel (202) is provided on the top wall of the box body (201) and communicates with the upper space (204).

[0129] In some embodiments, referring to FIG. 10, an annular baffle (215) may be provided on the side of the installation hole (214), and the annular baffle (215) may extend into the upper space (204). Accordingly, the second channel (202) may extend through the annular space formed by the annular baffle (215), thereby making the connection between the partition plate (203) and the second channel (202) reliable. In this way, when the cleaning device (100) is tilted or laid flat, and even if the partition plate (203) is not tilted (along with the baffle wall (211)) within the box body (201), the angle between the partition plates (203) with respect to the axial direction of the second channel (202) is prevented from changing, and the backflow prevention structure (230) on the partition plate (203) is maintained in its original position, thereby preventing dirt from flowing out of the lower space (205) through the backflow prevention structure (230).

[0130] FIG. 11 is a schematic diagram illustrating the structure of a backflow prevention valve according to some embodiments of the present disclosure. In some embodiments, as shown in FIG. 11, the backflow prevention valve (232) may include a fitting (233) and a flexible valve body (234). The fitting (233) is provided at the inlet of the valve body (234). In some embodiments, the size of the outlet cross-section of the valve body (234) along the second direction may be larger than the size of the outlet cross-section of the valve body (234) along the third direction. The second direction is perpendicular to the third direction. That is, the valve body (234) may be a flat, open valve body. Only by example, the outlet cross-section of the valve body (234) may be rectangular, the size of the valve body (234) along the second direction may mean the length of the rectangle, and the size of the valve body (234) along the third direction may mean the width of the rectangle. In some embodiments, the fitting (233) and the valve body (234) may be an integral structure formed by an injection molding process, a 3D printing process, and other integral molding processes. In some embodiments, the fitting (233) and the valve body (234) may be separated and then assembled by a connection process such as an adhesive connection or a clamping connection to form a backflow prevention valve (232). In some embodiments, the fitting (233) is installed on a bulkhead plate (203) corresponding to a first hole group (231). In some embodiments, to facilitate the installation of a backflow prevention valve (232) in the waste storage box (4) illustrated in FIG. 8, a conduit (208) may be provided on the lower surface (the side close to the bottom brush (2)) of a partition plate (203) corresponding to the first hole group (231), and a fitting (233) may be connected to the conduit (208) to realize a connection between the backflow prevention valve (232) and the partition plate (203). In some embodiments, the fitting (233) may be elastic so that it is easily secured to the conduit (208) with a sleeve and then optionally secured by a fixing member (e.g., a clamp).In some embodiments, the fitting (233) and the conduit (208) may also be connected via a flange. In some embodiments, the fitting (233) and the conduit (208) may be connected together via a screw connection. For example, a female thread may be installed in the fitting (233), and a male thread may be provided on the outer surface of the conduit (208) to match the female thread, and the fitting (233) and the conduit (208) may be connected to each other by screwing. It should be noted that the above method of installing the backflow prevention valve (232) on the bulkhead plate (203) is merely for illustrative purposes and is not limited thereto. Other processes for installing the backflow prevention valve (232) on the bulkhead plate (203) (e.g., adhesive connection, clamping connection, etc.) may also be configured and may not be repeated here.

[0131] In some embodiments, the backflow prevention structure (230) may include only one backflow prevention valve (232) installed in a partition plate (230) corresponding to all first through holes of the first hole group (231). For example, a conduit (208) is provided on the lower surface of a partition plate (203) corresponding to the first hole group (231), one end of the conduit (208) is connected to a fitting (233) of the backflow prevention valve (232), the other end is connected to the lower surface of the partition plate (230), and the other end of the conduit (208) is in contact with all first through holes of the first hole group (231), so that dirt from the upper space (204) can flow into the same backflow prevention valve after passing through all the first through holes. In some embodiments, the backflow prevention structure (230) may include a plurality of backflow prevention valves (232) installed on a partition plate (203) corresponding to one or more first through holes of a first hole group (231). For example, a plurality of conduits (208) are provided on the lower surface of the partition plate (230) corresponding to the first hole group (231), and one end of each of the plurality of conduits (208) is connected to a fitting (233) of a plurality of backflow prevention valves (232). The other end of each of the plurality of conduits (208) is connected to the lower surface of the partition plate (230), and the other end of each of the plurality of conduits (208) is connected to one or more first through holes of the first hole group (231), so that dirt in the upper space (204) can pass through one or more first through holes and then flow into the corresponding backflow prevention valve (232).

[0132] In some embodiments, the number of backflow prevention valves (232) of the backflow prevention structure (230) may be arranged according to the number of first through holes of the first hole group (231). In some embodiments, the ratio of the number of backflow prevention valves (232) of the backflow prevention structure (230) to the number of first through holes of the first hole group (231) may be 1:1. For example, each backflow prevention valve of the backflow prevention structure (230) is installed on a partition plate (230) corresponding to one of the first through holes of the first hole group. In some embodiments, the ratio of the number of backflow prevention valves (232) of the backflow prevention structure (230) to the number of first through holes of the first hole group (231) may be 1:2. For example, each backflow prevention valve of the backflow prevention structure (230) is installed on a partition plate (230) corresponding to two first through holes of the first hole group. In some embodiments, the ratio of the number of backflow prevention valves (232) of the backflow prevention structure (230) to the number of first through holes of the first hole group (231) may be 1:4. For example, each backflow prevention valve of the backflow prevention structure (230) is installed in a partition plate (230) corresponding to four first through holes of the first hole group. In some embodiments, the ratio of the number of backflow prevention valves (232) of the backflow prevention structure (230) to the number of first through holes of the first hole group (231) may be 1:5. For example, each backflow prevention valve of the backflow prevention structure (230) is installed in a partition plate (230) corresponding to five first through holes of the first hole group. In some embodiments, the ratio of the number of backflow prevention valves (232) of the backflow prevention structure (230) to the number of first through holes of the first hole group (231) may be 1:10. For example, each backflow prevention valve of the backflow prevention structure (230) is installed in a partition plate (230) corresponding to 10 first through holes of the first hole group.It should be understood that the ratio of the number of backflow prevention valves (232) of the backflow prevention structure (230) to the number of first through holes of the first hole group (231) may also be a different value.

[0133] In some embodiments, the fitting (233) is elastic, and the fitting (233) may also be made of the same material as the valve body (234). In some embodiments, the outer surface of the valve body (234) may be provided as a flat surface (235), which may close the valve body (234) (i.e., the flat opening is closed) by pressure from the external environment. When the cleaning device (100) is used in an upright position, as shown in FIG. 12, dirt from the upper space (204) flows into the valve body (234) through the first hole group (231) and the conduit (208). The pressure (P1) of the dirt acts on the valve body (234) and expands the valve body (234) (i.e., the flat opening is opened), and the dirt flows into the lower space (205) and can be stored. When the cleaning device (100) is used in a horizontal position, as shown in FIG. 13, the pressure (P2) on the dirt in the lower space (205) acts on the flat surface (235) of the valve body (234), thereby pressurizing the valve body (234) and closing the valve body (234) to prevent the dirt in the lower space (205) from leaking out of the valve body (234). At this time, the water temporarily stored in the upper space (204) is concentrated on the partition plate (203) and moves away from the inlet (219) of the gas outlet channel (218). Since the amount of water is small and the water is not pumped out of the box body (201), the probability of the motor stopping or being damaged can be greatly reduced. In some embodiments, when the cleaning device (100) is used in a lying position, if there is no or only a small amount of dirt in the lower space (205) to close the backflow prevention valve (232), the sucked dirt is also temporarily stored in the upper space (204) and near the partition plate (203) (some of the dirt may flow into the lower space (205)), and is not pumped out of the box body (201), and as a result, the motor is not stopped or damaged.

[0134] In some embodiments, as shown in FIG. 14, the backflow prevention valve (232) may be an elastic valve piece (236) disposed on the lower surface of the partition plate (203) corresponding to the first opening set (231). The elastic valve piece (236) adheres the first opening set (231) to the partition plate (203) and covers the first opening set (231) with the partition plate (203) to close the first opening set (231). Thus, the upper space (204) and the lower space (205) cannot communicate through the first opening set (231). When the cleaning device (100) is used in an upright position, the elastic valve piece (236) is pushed toward the lower space (205) and opened by the pressure of the dirt in the upper space (204) (the dotted line in FIG. 14 shows the elastic valve piece (236) that is pushed open), and the dirt can be fed into the lower space (205) through the first opening group (231) and stored. When the cleaning device (100) is laid down, the dirt in the lower space (205) presses the elastic valve piece (236) against the partition plate (203) and closes the first opening set (231), thereby preventing the dirt in the lower space (205) from leaking out to the outside.

[0135] As can be seen above, when the dirt that has passed through the backflow prevention valve (232) is located in the upper space (204), the backflow prevention valve (232) is fully opened [e.g., the valve body (234) is expanded or the elastic valve piece (236) is pushed open toward the lower space (205)] to ensure that the dirt can flow from the upper space (204) into the lower space (205). After the dirt has flowed into the lower space (205), the backflow prevention valve (232) is fully closed [e.g., by closing the valve body (234) or by attaching the elastic valve piece (236) to the partition plate (203) to close the first hole group (231)] so that the dirt in the lower space (205) does not flow back into the upper space (204) and the valve body (234), or the elastic valve piece (236) must have excellent elastic deformation ability. In order for the valve body (234) or elastic valve piece (236) to have excellent elastic deformation ability, in some embodiments, the material constituting the valve body (234) or elastic valve piece (236) may be rubber, silicone, etc. In some embodiments, the valve body (234) or elastic valve piece (236) may be made of rubber with a Shore hardness (D) in the range of 20 to 80 degrees. In some embodiments, the valve body (234) or elastic valve piece (236) may be made of rubber with a Shore hardness (D) in the range of 40 to 80 degrees. In some embodiments, the valve body (234) or elastic valve piece (236) may be made of rubber with a Shore hardness (D) in the range of 60 to 70 degrees. In some embodiments, the valve body (234) or elastic valve piece (236) may be made of silicone with a Shore hardness (D) of 35 degrees. Silicone with a Shore hardness (D) of 35 degrees has better elasticity and hardness, which provides better deformation ability and better rigidity to the valve body (234) or elastic valve piece (236). In addition, silicone has excellent corrosion resistance, which prevents the valve body (234) or elastic valve piece (236) from being corroded by dirt over a long period of time and shortening its lifespan.

[0136] In some usage situations, when the temperature of the waste sucked by the cleaning device (100) is high, the temperature of the backflow prevention valve (232) may rise due to the high temperature waste passing through the backflow prevention valve (232), and the high temperature may affect the elasticity of the valve body (234) or the elastic valve piece (236) of the backflow prevention valve (232), thereby reducing the efficiency of the waste passing through the backflow prevention valve (232). For example, if the elasticity of the valve body (234) or the elastic valve piece (236) decreases, the difficulty of opening the backflow prevention valve (i.e., guiding the backflow prevention valve (232) in one direction from the upper space (204) to the lower space (205)) increases, and the efficiency of the waste passing through the backflow prevention valve (232) decreases. Additionally, if the temperature rises, the valve body (234) or the valve elastic piece (236) may split, which may shorten the lifespan of the backflow prevention valve (232). In order to improve the heat resistance and operability of the backflow prevention valve even at high temperatures, in some embodiments, the heat resistance temperature of the material constituting the valve body (234) or the elastic valve piece (236) may be within the range of 25°C to 80°C. In some embodiments, the heat resistance temperature of the material constituting the valve body (234) or the elastic valve piece (236) may be 30°C to 70°C. In some embodiments, the heat resistance temperature of the material constituting the valve body (234) or the elastic valve piece (236) may be 40°C to 60°C.

[0137] In some embodiments, the backflow prevention valve (232) may also be a duckbill valve, a membrane check valve, a solenoid check valve, or another type of check valve. In some embodiments, the backflow prevention valve (232) shown in FIG. 11 may be replaced with another type of backflow prevention valve or check valve, which is within the scope of protection of the present disclosure as long as the other type of backflow prevention valve or check valve performs the same function as the backflow prevention valve (232).

[0138] FIG. 15 is a schematic diagram illustrating the structure of a cover body according to some embodiments of the present disclosure.

[0139] In some embodiments, as shown in FIGS. 8 and FIGS. 15, an adapter tube (217) may be provided inside a box body (201), and a cover body (216) may be in contact with one end of the adapter tube (217). Under the pressure of the cover body (216), the adapter tube (217) is stable so that shaking caused by the impact of dirt from the second channel (202) can be avoided even when the dirt flow rate is fast.

[0140] In some embodiments, as illustrated in FIG. 8, the other end of the adapter tube (217) may be connected to one end of the second channel (202). The other end of the adapter tube (217) is the inlet (223) of the adapter tube (217), and the other end of the second channel (202) is the outlet (224) of the second channel (202). For example, the inlet (223) of the adapter tube (217) may be paired with the outlet (224) of the second channel (202). In some embodiments, the adapter tube (217) has an outlet (220), and the outlet (220) of the adapter tube (217) may be offset from the cover body (216). For example, the end portion of the adapter tube (217) facing the cover body (216) may be closed, and the outlet (220) may be provided on the side wall of the adapter tube (217). By providing an outlet (220) on the side wall of the adapter tube (217), the path of the water-gas mixture inside the box body (201) can be extended to improve the water-gas separation effect. Additionally, the risk of water being pumped into the gas outlet channel (218) and reaching the motor is reduced, thereby improving the service life of the cleaning device (100).

[0141] In some embodiments, the outlet (220) of the adapter tube (217) is offset along the circumference from the inlet (219) of the gas outlet channel (218). That is, the inlet (219) of the gas outlet channel is arranged in a different direction from the outlet (220) of the adapter tube (217). For example, the outlet (220) is arranged on the side wall of the adapter tube (217) away from the inlet (219). For example, the outlet (220) of the adapter tube (217) and the inlet (219) of the gas outlet channel (218) are opposite each other along the radial direction of the adapter tube (217), and the height of the outlet (220) is lower than the height of the inlet (219) to maximize the distance between the outlet (220) and the inlet (219), thereby extending the path of the water-gas mixture inside the box body (201) and improving the gas-water separation effect. The radially opposite outlet (220) and inlet (219) of the adapter tube (217) can be understood as a line between the outlet (220) and the inlet (219) that crosses the axis of the adapter tube (217).

[0142] In some embodiments, the adapter tube (217) and the second channel (202) are integral structures. For example, the adapter tube (217) may be part of the second channel (202). In these embodiments, the adapter tube (217) may be straight and may have a diameter smaller than or equal to the diameter of the second channel (202) to facilitate channel passage through the installation hole (214) of the bulkhead plate (203).

[0143] In some embodiments, the adapter tube (217) and the second channel (202) are separate structures. For example, the adapter tube (217) may be manufactured separately and assembled with the second channel (202). Thus, the second channel (202) can be manufactured as just a straight tube, and since there is no need to consider the dimensional relationship between the adapter tube (217) and the installation hole (214), the manufacturing of the second channel (202) and the adapter tube (217) can be simplified.

[0144] In some embodiments, as illustrated in FIG. 15, a water level probe group (240) may be provided in the cover body (216), and the water level probe group (240) extends toward the lower space (205). The water level probe group (240) is configured to monitor the level of dirt inside the box body (201). When the level of dirt inside the box body (201) reaches a preset threshold, the motor (e.g., motor (33) or motor (34)) inside the cleaning device (100) stops rotating and warns the user to immediately empty the dirt inside the box body (201). In some embodiments, the water level probe group (240) may employ a positive water level probe. In some embodiments, the water level probe group (240) may also employ a unipolar water level probe or other types of water level probes.

[0145] In some embodiments, continuing to refer to FIG. 15, the water level probe group (240) includes a first probe group (241) and a second probe group (242) that extend toward the lower space (205). In some embodiments, the first probe group (241) may extend for a length greater than the extension length of the second probe group (242). In some embodiments, the second probe group (242) may extend into the upper space (204) and may be located directly above the first hole group (231). The first probe group (241) may be configured to monitor the water level inside the box body (201) when the cleaning device (100) is used in an upright position. When the water level inside the box body (201) reaches a preset threshold, the motor may stop rotating and warn the user to quickly empty the dirt inside the box body (201). The second probe group (242) may be configured to monitor the water level inside the box body (201) when the cleaning device (100) is used in a flat position. When the water level monitored by the second probe group (242) reaches a preset threshold, the motor may stop rotating and remind the user to immediately discard the dirt. As previously described, when the cleaning device (100) is used in a flat position, the backflow prevention structure (230) provided in the partition plate (203) can prevent dirt from the lower space (205) from flowing back into the upper space (204) through the backflow prevention structure (230) and prevent the motor from stopping rotating, so that the cleaning device (100) can still clean normally. At this time, dirt sucked into the upper space (204) through the second channel (202) can be accumulated in the upper space (204) by the partition plate (203). If there is too much dirt accumulated in the upper space (204) and flows into the cover body, the dirt may first flow into the second probe group (242). The second probe (242) can generate a signal to stop the rotation of the motor, thereby preventing the dirt from being sucked into the motor and causing damage to the motor.Accordingly, by providing a first probe group (241) and a second probe group (242), the water level inside the box body (201) can be monitored in real time, thereby preventing dirt from being sucked into the motor and causing damage to the motor. As a result, the lifespan of the cleaning device (100) is greatly extended.

[0146] In some embodiments, the first probe group (241) may extend into the lower space (205). In other words, the first probe group (241) may penetrate the partition plate (203) to reach the lower space (205). Thus, before the dirt inside the box body (201) (lower space (205)) reaches the partition plate (203), the first probe group (241) detects a critical level and stops the rotation of the motor. Accordingly, the dirt can be further prevented from entering the motor, thereby extending the lifespan of the cleaning device (100). In some embodiments, the depth to which the first probe group (241) enters the lower space (205) may be adjusted according to actual conditions. For example, the depth to which the first probe group (241) enters the lower space (205) may be adjusted according to the height of the partition plate (203) inside the box body (201). In some embodiments, the higher the partition plate (203) is inside the box body (201), the deeper the depth to which the first probe group (241) enters the lower space (205).

[0147] In some embodiments, the first probe group (241) may be positioned in the upper space (204) in close proximity to the bulkhead plate (203). According to this structure, when the bulkhead plate (203) is blocked, the level of dirt in the lower space (205) is lowered, and even when dirt accumulates in the upper space (204), the first probe group (241) can still accurately monitor the level of dirt and prevent dirt from being sucked into the motor. In some embodiments, the position of the first probe group (241) in the upper space (205) may be adjusted according to actual conditions. In some embodiments, the first probe group (241) may extend into the lower space (205) or the upper space (204). Alternatively, depending on actual conditions, the first probe group (241) may be provided in both the upper space (204) and the lower space (205).

[0148] In some embodiments, the second probe group (242) may be positioned above the outlet (220) of the adapter tube (217). Accordingly, the possibility of misjudgment by the second probe group (242) can be reduced by preventing dirt from the outlet (220) from being sprayed directly onto the second probe group (242).

[0149] In some embodiments, continuing to refer to FIG. 15, two flow baffles (243) extending into the upper space (204) may also be provided in the cover body (216), and the two flow baffles (243) are spaced apart along the circumference of the cover body (216). At least a portion of the side edge (244) area of ​​each flow baffle (243) is spaced apart by the side wall of the box body (201). The outlet (224) of the second channel (202) may be positioned between the two flow baffles (243). The two flow baffles (243) allow splashing dirt to flow downward, thereby preventing dirt from splashing into the box body (201) and potentially adversely affecting the use of the cleaning device (100). Additionally, air sucked into the box body (210) from the second channel (202) bypasses the flow baffle (243) and reaches the inlet (219) of the gas outlet channel (218) of the cover body (216), thereby making the movement path of the water-gas mixture more winding, which can extend the movement path of the water-gas inside the box body (201) and improve the gas-water separation effect. Also, as shown in FIG. 15, a second probe group (242) may be placed between the two flow baffles (243). Accordingly, the cover body (216) can be made compact, which is advantageous for reducing the radial size of the dirt storage box (4), and the cleaning device (100) is small, concise, flexible, and facilitates cleaning in narrow spaces.

[0150] In some embodiments, the upper region (245) of the side edge (244) of the flow baffle (243) contacts the side wall of the box body (201), the lower region (246) is spaced apart from the side wall of the box body (201), and the outlet (224) of the second channel (202) is arranged to correspond to the upper region (245) of the side edge (244). Through this structure, the flow baffle (243) not only prevents dirt from splashing throughout the interior of the box body (201), but also forces the water-gas mixture to flow downward and across the flow baffle (243), thereby lengthening the path of the water-gas mixture within the box body (201) and improving the gas-water separation effect.

[0151] In some embodiments, the cover body (216) may be provided with a backing plate (247) that can be positioned between the inlet (219) of the gas outlet channel (218) and the adapter tube (217) (outlet (220)), and the backing plate (247) may be connected between two flow baffles (243). Thus, the water-gas mixture may flow downward through the backing plate (247) before reaching the inlet (219) of the gas outlet channel (218), which also helps to extend the path of the water-gas mixture within the box body (201) and provides a good gas-water separation effect. In some embodiments, the extension length of the backing plate (247) may be smaller than the extension length of the flow baffle (243). The extension lengths of the backing plate (247) and the flow baffle (243) may be the size of the backing plate (247) and the size of the flow baffle (243) along the length of the device body (1), respectively. Accordingly, the flow baffle (243) and the backing plate (247) prevent excessive blockage of the path of the water-gas mixture and ensure a smooth airflow with a better cleaning effect when using the cleaning device (100). To effectively extend the path of the water-gas mixture within the box body (201), in some embodiments, the extension length of the backing plate (247) may be within the range of 50 mm to 100 mm. In some embodiments, the extension length of the backing plate (247) may be within the range of 60 mm to 100 mm. In some embodiments, the extension length of the backing plate (247) may be within the range of 70 mm to 95 mm. In some embodiments, the extended length of the backing plate (247) may be within the range of 70 mm to 95 mm. In some embodiments, the extended length of the backing plate (247) may be within the range of 75 mm to 90 mm.To prevent the flow baffle (243) and the backing plate (247) from excessively blocking the path of the water-gas mixture, in some embodiments, the difference between the extension length of the flow baffle (243) and the extension length of the backing plate (247) may be in the range of 25 mm to 40 mm. In some embodiments, the difference between the extension length of the flow baffle (243) and the extension length of the backing plate (247) may be 28 mm. In some embodiments, the difference between the extension length of the flow baffle (243) and the extension length of the backing plate (247) may be 28 mm. The difference between the extension length of the folded flow plate (243) and the extension length of the backing plate (247) may be 28 mm to 37 mm. In some embodiments, the difference between the extension length of the folded flow plate (243) and the extension length of the backing plate (247) may be 30 mm to 35 mm.

[0152] In some embodiments, when the adapter tube (217) is split in the second channel (202), a water baffle (not shown in the drawing) may be provided between the adapter tubes (217) above the outlet (220) and below the second probe group (242). The water baffle may be in contact with the side wall of the box body (201). By providing the water baffle plate, the second probe group (242) and the outlet (220) of the adapter tube (217) are separated, effectively preventing dirt from being sprayed directly onto the second probe group (242), thereby further reducing the possibility of misjudgment.

[0153] In some embodiments, as shown in FIG. 16, an installation area (250) is provided on the circumferential outer surface of the box body (201) to interact with the device body (1), and a backflow prevention structure (230) is positioned radially spaced from the installation area (250) of the partition plate. When viewing the cleaning device (100) as a whole, the installation area (250) is located on the front side of the box body (201), and the backflow prevention structure (230) is positioned inside the box body (201) close to the rear side of the box body (201) (as shown in FIG. 1 to 4). Accordingly, when the cleaning device (100) is laid flat (as shown in FIGS. 17 and 18), the backflow prevention structure (230) is closed and positioned at a lower position in the second hole group (210), preventing dirt from the lower space (205) from flowing into the upper space (204) through the backflow prevention structure (230), thereby allowing the cleaning device (100) to be used normally. In some embodiments, in other types of cleaning devices, a dirt storage box (4) may be provided on the front side of the device body (1), provided that the way the cleaning device is laid flat for use is suitable for the arrangement position of the backflow prevention structure (230) (see FIGS. 5 to 7 and FIG. 18), and this may not be repeated here. Additionally, as shown in FIG. 18, a dirt storage box (4) is provided on the front side of the device body (1), and it should be noted that a backflow prevention structure (230) is positioned radially close to the installation area (250) of the partition plate (203). As a result, when the cleaning device (100) is laid flat (see FIG. 18), the backflow prevention structure (230) is closed and positioned at a low position in the second hole group (210), thereby preventing dirt from the lower space (205) from flowing into the upper space (204) through the backflow prevention structure, and allowing the cleaning device (100) to be used normally.

[0154] Hereinafter, various usage situations of the cleaning device (100) can be described with reference to FIGS. 4 and FIGS. 17. Referring to FIGS. 4, FIGS. 4 illustrates the cleaning device (100) in a first usage situation. The first usage situation may include a situation in which a user uses the cleaning device (100) in an upright position. When the user uses the cleaning device (100) in an upright position, the motor (34) rotates and the water spray system (e.g., the cleaning fluid supply assembly of the previous disclosure) is activated, and clean water is sprayed from the cleaning fluid box to the floor. Dirt on the floor is sucked in by the floor brush (2) and then flows into the upper space (204) of the box body (201) through the first channel (6) and the second channel (202). The waste is introduced into the lower space (205) and stored through the first hole group (231) (and backflow prevention valve (232)) and / or the second hole group (210) of the partition plate (203). Solid waste in the waste is filtered by the partition plate (203) and remains in the upper space (204). When the first probe group (241) detects that the waste level in the box body (201) has reached a critical value, the motor (34) stops rotating and warns the user. For example, the first probe group (241) may warn the user to immediately discard the waste in the box body (201).

[0155] Referring to FIG. 17, FIG. 17 illustrates a second usage situation of the cleaning device (100). The second usage situation may include a situation in which the user uses the cleaning device (100) in a lying position (or tilted position). When the user uses the cleaning device (100) in a flat position, due to the action of the backflow prevention structure (230) on the partition plate (203), the dirt in the lower space (205) does not reach the upper space (204) and remains in the lower space (205). The motor (34) rotates to operate the spraying system, spraying clean water from the clean water box onto the floor, and the dirt is sucked back into the upper space (204) of the box body (201) through the second channel (202). At this time, the dirt is temporarily stored in the upper space (204), and the motor (34) rotates normally so that the cleaning device (100) is used normally. When the second probe group (242) detects that the level of the dirt temporarily stored in the upper space (204) has reached a threshold, the motor (34) stops rotating and warns the user. When the cleaning device (100) is in an upright position, the dirt temporarily stored in the upper space (204) can be introduced into the lower space (205) through the first hole group (231) (and backflow prevention valve (232)) and / or the second hole group (210).

[0156] FIG. 19 is a schematic diagram illustrating a cross-section (I) of a dirt storage box according to some embodiment of the present disclosure. FIG. 20 is a schematic diagram illustrating a cross-section (II) of a dirt storage box according to some embodiment of the present disclosure. In some embodiments, the dirt storage box (4) of the cleaning device (100) illustrated in FIG. 1 to 7 may specifically be the dirt storage box (300) illustrated in FIG. 19 and FIG. 20.

[0157] As illustrated in FIGS. 19 and 20, the waste storage box (300) may include a box body (301) and a waste pipe (302). The waste pipe (302) may be a second channel (202) within the waste storage box (4) illustrated in FIG. 8, or the waste pipe (302) may include at least a second channel (202) in the waste storage box (4) illustrated in FIG. 8. The box body (301) includes a bottom surface (303), a waste inlet (304) is arranged on the bottom surface (303), and the waste pipe (302) is formed to extend upward from the waste inlet (304). A waste outlet (3021) is arranged in the upper part of the waste pipe (302), and the fluid (M) flowing in from the waste pipe (302) is separated into a mixed liquid (a) and a mixed gas (c) at the waste outlet (3021). The mixed liquid (a) separated at the waste outlet (3021) flows downward by gravity and is stored at the bottom position of the box body (301), thereby realizing the first type of filtration of the waste storage box (300), namely, the separation of the mixed liquid and the mixed gas (c). In some embodiments, a waste inlet (304) may be provided on the side of the box body (301), and a cyclone filter assembly (305) may be provided inside the box body (301), so that dust flowing in from the waste inlet (304) can perform dust-gas separation through the cyclone filter assembly (305). For example, the mixed liquid and the mixed gas (c) are separated.

[0158] In some embodiments, referring to FIGS. 19 and FIGS. 20, the waste storage box (300) may further include a cover body (306) and a cyclone filter assembly (305). In some embodiments, the cyclone filter assembly (305) may be a cyclone separation structure (260) shown in FIG. 8, or a component having a structure similar to or performing the same function as the cyclone separation structure (260). Alternatively, the cyclone separation structure (260) shown in FIG. 8 may be part of the cyclone filter assembly (305). The cover body (306) may include a main body (3061), the main body (3061) is fitted into the top of the box body (301), the main body (3061) is provided with an air inlet (3062), and the cyclone filter assembly (305) may be provided to the main body (3061) and connected to the air inlet (3062). The air inlet (3062) is located above the waste outlet (3021). In some embodiments, the air inlet (3062) is the inlet (219) shown in FIG. 8, or has a structure similar to or the same function as the air inlet (219). The mixed gas (c) separated from the waste outlet (3021) is lighter in mass and continues to rise to the inlet (3062) and enters the cyclone filter assembly (305), which can filter the mixed gas (c).Dust (d) in the mixed gas (c) remains in the cyclone filter assembly (305), and the cleaning gas (e) filtered by the action of the vacuum environment is discharged from the cyclone filter assembly (305) and discharged out of the cleaning device (100) through the motor of the cleaning device (100) [e.g., motor (34) or motor (33) in the portable vacuum cleaner (3)], thereby preventing the discharge of gas from the motor containing a lot of dust (d), ensuring the cleanliness of the external environment, and also preventing the problem of respiratory disease caused by the operator inhaling too much dust (d), thereby ensuring the physical health of the operator, and thus realizing the separation of the cleaning gas (e) and dust (d), which is the second filtration process of the dirt storage box (300).

[0159] In some embodiments, as illustrated in FIG. 21, the air inlet (3062) may be positioned close to the waste outlet (3021), but this causes some of the mixed liquid sprayed from the waste pipe (302) to be sprayed into the air inlet (3062), and since the cyclone filter assembly (305) cannot filter moisture, the moisture introduced into the air inlet (3062) may be introduced sequentially into the cyclone filter assembly (305), HEPA, and motor. Gas containing moisture tends to reduce the permeability of the HEPA, and a humid environment tends to cause bacteria to proliferate in the HEPA. Since the HEPA is a high-efficiency filter (filter) commonly used in cleaning devices that filters out 99% of fine dust in the air, it can purify and remove air passing through the cleaning device and minimize secondary pollutants. In addition, moisture-containing gas may be sucked into the motor, causing a short circuit in the motor and potentially causing a malfunction of the cleaning unit (100).

[0160] To solve the above problem, as shown in FIG. 19, the dirt outlet (3021) and the air inlet (3062) are positioned on both sides of the central axis (3012) of the box body (301), and a certain distance is left between the dirt outlet (3021) and the air inlet (3062) so that the problem of the mixed liquid (a) being sprayed directly from the dirt outlet (3021) to the air inlet (3062) can be prevented. The mixed gas (c) passes through a long path after being discharged from the dirt outlet (3021) and before entering the air inlet (3062), and the moisture of the mixed gas (c) can be separated from the mixed gas (c) in the flow of the long path, thereby preventing moisture from entering the HEPA or motor, thus preventing bacterial growth in the HEPA, preventing short circuits in the motor, and ensuring normal operation of the cleaning device (100).

[0161] In some embodiments, as shown in FIGS. 19, 20, and 22, the waste outlet (3021) may be provided on the waste pipe (302) side at the rear from the inlet (3062). As illustrated in FIG. 22, the distance along the horizontal direction between the waste outlet (3021) and the inner wall of the box body (301) opposite the waste outlet (3021) is L4, and the mixed gas (c) discharged from the waste outlet (3021) first moves along the horizontal direction for a length (L4) toward the inner wall of the box body (301) opposite the waste outlet (3021), the mixed gas (c) first moves horizontally for a length (L4) toward the inner wall of the box body (301) opposite the waste outlet (3021), reaches the inner wall of the box body (301) opposite the waste outlet (3021), the mixed gas (c) collides with the inner wall of the box body (301) and then bends, and the mixed gas (c) moves from the inner wall of the box body (301) toward the direction of the air inlet (3062). Compared to the mixed gas (c) coming out directly from the waste outlet (3021) toward the air inlet (3062), according to the arrangement of the present embodiment, the travel path of the mixed gas (c) from the waste outlet (3021) to the air inlet (3062) is extended. For example, the extended length of the travel path is caused by the mixed gas (c) making a round-trip movement along the horizontal direction between the water outlet (3021) and the inner wall of the box body (301) opposite the water outlet (3021). For example, the extended length is 2*L4, and the length of the travel path of the mixed gas (c) from the waste outlet (3021) to the air inlet (3062) is 2*L4. The path through which the mixed gas (c) passes from the dirt outlet (3021) to the air inlet (3062) is long, and the moisture and dust (d) mixed in the mixed gas (c) are well separated from the mixed gas (c) by gravity, thereby improving the cleaning degree of the cleaning gas discharged from the cyclone filter assembly (305) and further reducing the humidity of the cleaning gas discharged from the cyclone filter assembly (305).

[0162] In some embodiments, as illustrated in FIGS. 19, 20 and 22, the cover body (306) further includes a baffle (3063). The baffle (3063) extends downward from the main body (3061) and surrounds the waste outlet (3021). The baffle (3063) forms a channel through which the mixed gas (c) passes to the bottom surface (303), and the waste outlet (3021) and air inlet port (3062) are positioned on both sides of the baffle (3063).

[0163] In some embodiments, regarding the role of the baffle plate (3063), first, the baffle plate (3063) partially blocks the mixed liquid sprayed from the waste outlet (3021), thereby preventing the mixed liquid from being directly sucked through the inlet port (3062) of the cyclone filter assembly (305) and reducing the risk of a short circuit in the motor.

[0164] In some embodiments, as illustrated in FIGS. 19, 20 and 22, a first portion of the mixed gas (c) flowing from the waste outlet (3021) may have an upward fractional velocity, and the first portion of the mixed gas tends to move upward first, then the first portion of the mixed gas bends in reverse and moves to the bottom surface of the main body (3061) and then moves downward, and the first portion of the mixed gas after bending in reverse passes through the channel and moves upward from the channel to the air inlet (3062). The mixed gas passing from the waste outlet (3021) to the air inlet (3062) is bent several times along the vertical direction to increase the first part of the mixed gas, and the moisture and dust mixed in the first part of the mixed gas are separated from the first part of the mixed gas by gravity, thereby further improving the cleaning degree of the cleaning gas discharged from the cyclone filter assembly (305), and the cleaning degree of the cleaning gas (e) can be further improved, and the humidity of the cleaning gas discharged from the cyclone filter assembly (305) can be further reduced.

[0165] In some embodiments, as illustrated in FIGS. 19, 20 and 22, a second portion of the mixed gas (c) entering from the dirt outlet (3021) may have a downward fractional velocity, and the second portion of the mixed gas (c) tends to move upward first, and the second portion of the mixed gas moves in the reverse direction into the channel and moves upward from the channel to the air inlet (3062). The path of the second portion of the mixed gas passing from the dirt outlet (3021) to the air inlet (3062) is increased by bending the first portion of the mixed gas vertically several times, and as the moisture and dust mixed in the mixed gas are separated from the first portion of the mixed gas by gravity, the cleaning degree of the cleaning gas discharged from the cyclone filter assembly (305) may be further improved, the cleaning degree of the cleaning gas (e) may be further improved, and the humidity of the cleaning gas discharged from the cyclone filter assembly (305) may be further reduced.

[0166] In some embodiments, the structure of a waste pipe (302) is illustrated in FIGS. 19, 20, and 22, and the waste pipe (302) may include a pipe body (3022) and an adapter tube (3023). The pipe body (3022) is formed with a waste inlet (304) extending upward, and the adapter tube (3023) includes a first line (30231), a transfer pipe (30232), and a second pipeline (30233) connected sequentially. The first pipe (30231) is coaxially and detachably connected to the pipe body (3022), the first pipe (30231) is perpendicular to the second pipe (30233), and a waste outlet (3021) is provided on the second pipe (30233). Because the pipe body (3022) is long, if the pipe body (3022) is molded integrally with the adapter tube (3023), the mold of the waste pipe (302) becomes very complex, resulting in a low success rate for opening the mold and a high cost for opening the mold. In this embodiment, the waste pipe (302) is detachably disassembled into two parts, a pipe body (3022) and an adapter tube (3023), and the structure of the mold corresponding to the pipe body (3022) and the adapter tube (3023) is simple, so that each part is manufactured independently, the success rate of opening the mold is effectively improved and the cost of opening the mold is effectively reduced. Additionally, since the inside of the adapter tube (3023) can be bent to form corners, dust or foreign matter may accumulate inside the adapter tube (3023), and over a long period of time, the flow rate of waste discharged from the waste outlet (3021) may be affected and the filtration efficiency of the waste outlet (3021) may be affected. In this embodiment, the tube body (3022) and the adapter tube (3023) are detachably connected, and the operator can remove the adapter tube (3023) from the tube body (3022) to clean the inside of the adapter tube (3023) well and quickly.In some embodiments, the adapter tube (3023) may be the adapter tube (217) shown in FIG. 8, or may be a structure or component having a structure similar to or the same function as the adapter tube (217).

[0167] In some embodiments, as illustrated in FIG. 22, the distance along the vertical direction between the centerline of the second pipeline (30233) and the air inlet (3062) is L1, and the distance between the centerline of the second pipeline (30233) and the bottom end of the baffle plate (3063) is L2. If the existing waste outlet (3021) is arranged to face upward, the path through which the existing mixed gas (c) passes before entering the cyclone filter assembly (305) becomes L1. In this embodiment, through the arrangement of the baffle (3063), the path through which the mixed gas (c) passes before entering the cyclone filter assembly (305) becomes 2*L2+L1, thereby lengthening the path through which the mixed gas (c) passes before entering the cyclone filter assembly (305). Naturally, the path through which the mixed gas (c) passes is the length of the path through which the mixed gas (c) passes. In some embodiments, to appropriately adjust the length of the waste storage box (300) along the vertical direction and to prevent the waste storage box (300) from becoming too large in the vertical direction, the L2 / L1 ratio of the waste storage box (300) may be 0.9 to 3.

[0168] In some embodiments, as shown in FIG. 22, the maximum width of the inner wall of the box body (301) is W1, the distance between the inlet port (3062) side away from the waste outlet (3021) along the horizontal direction and the waste outlet (3021) is W2, and the W2 / W1 ratio is 3 / 4 to 7 / 8. According to the above dimensions, in the limited space of the box body (301), by making the distance between the inlet port (3062) and the waste outlet (3021) as large as possible, the distance through which the mixed gas (c) passes in the horizontal direction from the waste outlet (3021) to the inlet (3062) can be realized as long as possible.

[0169] In some embodiments, as shown in FIG. 19 and FIG. 22, the distance along the horizontal direction between the end surface of the second pipeline (30233) and the outer surface of the pipe body (3022) is L3, and the distance between the end surface of the second pipeline (30233) along the horizontal direction and the inner wall of the box body (301) is L4, and the ratio of L3 / L4 is in the range of 1 / 2 to 1, so that the distance from the waste outlet (3021) to the inner wall of the box body (301) is effectively shortened, and a large amount of mixed liquid (a) sprayed from the waste outlet (3021) flows in and forms a catch wall with the inner wall of the box body (301), thereby causing a large amount of dry waste (or solid waste) in the mixed liquid (a) to catch on the inner wall of the box body (301) and realizing a good separation effect between dry waste (f) and wet waste (b) in the mixed liquid (a).

[0170] In some embodiments, as illustrated in FIG. 19, FIG. 20, FIG. 23 and FIG. 24, the baffle plate (3063) is provided with a plug groove (30631) extending along the vertical direction, and the plug groove (30631) forms a plug-in port (30632) at the lower end of the baffle plate (3063), and the second pipeline (30233) can be inserted into the plug groove (30631) by the plug-in port (30632) and slide along the plug groove (30631), and the plug groove (30631) is compatible with the second pipeline (30233) to realize a guiding effect when installing the cover body (306) on the box body (301). Additionally, the second pipeline (30233) is compatible with the plug groove (30631) to stabilize the cover body (306) and the box body (301), and the waste storage box (300) can prevent the cover body (306) and the box body (301) from becoming loose during use.

[0171] In some embodiments, as illustrated in FIGS. 19, 24 and 25, the adapter tube (3023) further comprises a blocking plate (30234). The blocking plate (30234) is provided around the second pipeline (30233) and extends in an upward and downward direction, and the blocking plate (30234) is provided on one side of the baffle plate (3063) when the second pipeline (30234) is inserted into the plug groove (30631). The blocking plate (30234) blocks the plug groove (30631), and the blocking plate (30234) and the baffle plate (3063) form a complete shielding plate, thereby preventing a portion of the mixed gas (c) from passing directly through the plug groove (30631) and entering the air inlet (3062), so that the mixed gas (c) enters the air inlet (3062) after passing through the channel, and the mixed gas (c) passes through a relatively long path, ensuring that the automatic separation of moisture and dust is improved. In addition, as the trajectory length of the mixed liquid along the surface of the object is increased, a large amount of dry waste (f) of the mixed liquid (a) remains on the surface of the object, thereby ensuring a constant separation effect between the dry waste (f) and wet waste (b) in the mixed liquid (a).

[0172] In some embodiments, as illustrated in FIGS. 23 and 24, the plug groove (30631) includes a plug segment (30633) and a guide segment (30634) connected from bottom to top. A plug-in port (30632) is located at the bottom of the plug segment (30633), the width of the plug segment (30633) decreases from bottom to top, the width of the top of the plug segment (30633) is equal to the width of the guide segment (30634), and the width of the guide segment (30633) is equal to the diameter of the second pipeline (30233). As the second pipeline (30233) gradually slides from the plug segment (30633) into the guide segment (30634) through the arrangement of the plug segment (30633), there may be a specific deviation in the alignment of the plug groove (30631) and the second pipeline (30233), thereby realizing the accurate alignment of the plug segment (30633) and the second pipeline (30233) along the circumferential direction.

[0173] In some embodiments, as shown in FIG. 26, the first pipeline (30231) is provided with a first through hole (302311) and a second through hole (302312) connecting from the bottom to the top, and the second through hole (302312) is connected to a transfer pipe (30232). The cross-sectional area of ​​the first through hole (302311) is larger than the cross-sectional area of ​​the second through hole (302312), and a contact surface (302313) is formed at the joint location of the first through hole (302311) and the second through hole (302312). The tube body (3022) is inserted into the first through hole (302311) and is in contact with the contact surface (302313), which indicates that the tube body (3022) and the adapter tube (3023) are installed in the correct positions, thereby improving the efficiency of the user assembling the tube body (3022) and the adapter tube (3023) together.

[0174] By combining FIGS. 19, FIGS. 20, FIGS. 22 and FIGS. 27, the structure of a cyclone filter assembly (305) is illustrated, wherein a main body (3061) is provided with a receiving cavity (3064) connected to an air inlet (3062), and the cyclone filter assembly (305) is provided in the receiving cavity (3064) and connected to the main body (3061). A mixed gas (c) is sequentially connected to the main body (3061), and the mixed gas (c) passes through an air inlet (3062), a receiving cavity (3064), and a cyclone filter assembly (305) for dust-gas separation. A cleaning gas (e) is discharged from the cyclone filter assembly (305), and dust (d) in the mixed gas (c) flowing through the cyclone channel remains in the main body (3061) under the action of the cyclone and gravity, thereby realizing an excellent separation effect between the cleaning gas (e) and the dust (d).

[0175] In some embodiments, as illustrated in FIG. 27, the main body (3061) is configured such that the upper portion of the main body (30611) is positioned at the upper position. The upper portion of the main body (30611) is provided with a plug interface (30612) connected to a receiving cavity (3064), and the cyclone filter assembly (305) is inserted into the receiving cavity (3064) through the plug interface (30612) to realize a detachable connection between the cyclone filter assembly (305) and the main body (3061), realize rapid assembly and separation of the cyclone filter assembly (305) and the cover body (306), facilitate the operator to clean impurities from the cyclone filter assembly (305), and ensure that the cyclone filter assembly (305) has a relatively large filtration effect against future dust. Additionally, after separating the cover body (306) from the box body (301), by filtering the cyclone filter assembly (305) from the cover body (306), it is possible to check for any impurities blocking the cyclone channel between the cyclone filter assembly (305) and the cover body (306), and if necessary, the cyclone channel can be cleaned.

[0176] In some embodiments, as illustrated in relation to FIGS. 19, 20, 27, 28, 29 and 30, the cyclone filter assembly (305) may include a connecting tube (3051) and a first clamping portion (3052). The connecting tube (3051) is provided with a connecting tube channel, and the connecting tube channel has an upper open end and a lower open end. The upper open end is an air outlet port (30511), and a first clamping portion (3052) is arranged around the periphery of the communication tube (3051), and the periphery of the first clamping portion (3052) abuts against the side wall of the receiving cavity (3064), and the first clamping portion (3052) includes a spiral bottom plate (30521) connected to the communication tube (3051), and the spiral bottom plate (30521) is spirally wrapped around the periphery of the communication tube (3051). The spiral bottom plate (30521), the communication tube (3051), and the main body (3061) together form a cyclone channel. The air inlet (3062) is connected to the cyclone channel, and the mixed gas passes sequentially through the air inlet (3062), the cyclone channel, and the connecting tube (3051) to achieve separation of cyclone dust and gas, after which the cleaning gas (e) is discharged from the outlet (30511) located at the top of the connecting tube (3051).

[0177] In some embodiments, as illustrated in FIGS. 27, 28 and 29, the first clamping portion (3052) further comprises a peripheral side plate (30522), a blocking baffle (30523), and a top plate (30524). The peripheral side plate (30522) is in the shape of a ring, and the width of the unfolded peripheral side plate (30522) gradually widens. The peripheral side plate (30522) is positioned around the communication tube (3051) and arranged at a distance from the periphery of the communication tube (3051), and the bottom line of the peripheral side plate (30522) forms a spiral shape around the periphery of the communication tube (3051). A wide end (free end) is arranged at a distance from the communication tube (3051). The lower line of the circumferential side plate (30522) spirally wraps around the periphery of the connecting pipe (3051), and the free end of the circumferential side plate (30522) is blocked and connected to the periphery of the connecting pipe (3051) through the blocking plate (30523). As shown in FIG. 29, the upper end of the circumferential side plate (30522) is connected to the periphery of the connecting pipe (3051) through the blocking plate (30523). The outer surface of the connecting pipe (3051) can be connected via the top plate (30524), and the lower portion of the circumferential side plate (30522) is connected to the outer surface of the connecting pipe (3051) via the spiral bottom plate (30521), and the spiral bottom plate (30521) wraps the connecting pipe (3051) at an angle of more than 360 degrees in the circumferential direction, and the lower portion of the spiral bottom plate (30521) is positioned below the upper portion (30521) and along the vertical direction in the portion of the spiral bottom plate (30521) positioned oppositely. The upper two portions of the opposite spiral bottom plate (30521) form a concave space. The concave space can be connected to an air inlet (3062), as shown in FIG. 19.As illustrated in FIG. 27, the first clamping portion (3052) can block the plug port (30612). As illustrated in FIG. 19 and FIG. 20, the mixed gas (c) introduced from the plug port (30612) moves downward due to the blocking of the first clamping portion (3052). As illustrated in FIG. 19, FIG. 27, and FIG. 28, the mixed gas (c) rotates spirally due to the guiding action of the spiral base plate (30521). The blocking effect of the first clamping portion (3052) and the guiding effect of the spiral base plate (30521) work together to cause the mixed gas (c) to move spirally downward, thereby producing a relatively large cyclone separation effect. As illustrated in FIG. 19, the cleaning gas obtained by the cyclone separation action is introduced from the lower open end of the connecting tube (3051), moves upward to the air outlet (30511), and is discharged to the outside of the cyclone filter assembly (305). Additionally, as illustrated in FIG. 19 and FIG. 29, the top plate (30524) is provided with a top plate opening (305241) connected to the air outlet (30511), and the cleaning gas discharged from the air outlet (30511) can be discharged through the top plate opening (305241).

[0178] In some embodiments, as illustrated in FIG. 19, FIG. 20, FIG. 30, and FIG. 31, the outer contour of the cross-section of the first clamping portion (3052) gradually decreases from the top to the bottom. As illustrated in FIG. 20, the receiving cavity (3064) includes a first cavity and a second cavity connected in a line from the top to the bottom, the size and shape of the first cavity match that of the first clamping portion (3052), and the cross-sectional area of ​​the second cavity is smaller than the cross-sectional area of ​​the first cavity, thereby enabling the first clamping portion (3052) to be clamped at the position of the first cavity and enabling a good clamping fixing effect of the cyclone filter assembly (305) and the cover body (306). Additionally, since the outer contour of the cross-section of the first clamping part (3052) gradually decreases from the top to the bottom, it is convenient for the user to remove the cyclone filter assembly (305) from the receiving cavity (3064).

[0179] In some embodiments, as illustrated in FIGS. 19 and 20, the cyclone filter assembly (305) may include a cyclone filter mechanism (3053) (e.g., the cyclone separation structure (260) illustrated in FIG. 8) and a flexible rubber (3054). The cyclone filter mechanism (3053) is positioned within a receiving cavity (3064), and the flexible rubber (3054) is connected to the cyclone filter mechanism (3053), with at least a portion of the flexible rubber (3054) protruding outward from the periphery of the cyclone filter mechanism (3053), and the flexible rubber (3054) protruding outward from the periphery of the cyclone filter mechanism (3053) is connected to the upper portion (30611) of the cover body. The upper part (30611) of the cover body can provide a large support effect for the cyclone filter assembly (305), and furthermore, due to the soft texture of the soft rubber (3054), even if the soft rubber (3054) is in contact with the upper part of the cover body for a long period of time, damage to the soft rubber (3054) or the upper part (30611) of the cover body can be prevented.

[0180] In some embodiments, as illustrated in FIGS. 29, 30, and 31, the flexible rubber (3054) may include a second upper surface (30541) and a connecting portion (30542) connected to the second upper surface (30541). The second upper surface (30541) is positioned on the upper surface of the upper plate (30524), and the connecting portion (30542) is clamped around the upper plate (30524), and an annular snapping groove (305243) is provided at the location of the circumferential side plate (30522) adjacent to the second upper surface (30541). A portion of the connecting portion (30542) is received in the clamping groove (305243), and a portion of the connecting portion (30542) protrudes outward from the periphery of the circumferential side plate (30522) to achieve fixation between the flexible rubber (3054) and the top plate (30524). As illustrated in FIG. 19 and FIG. 31, an upper opening (30544) is provided in the second upper surface (30541), and cleaning gas discharged from the top plate opening (305241) is discharged through the upper opening (30544) and then enters the motor of the cleaning device (100).

[0181] In some embodiments, as shown in FIGS. 27 and 28, the flexible rubber (3054) may include two lugs (30543) positioned on both sides thereof, and as shown in FIG. 29, the top plate (30524) includes two lug clamping portions (305242). Each of the two lug clamping portions (305242) is clamped and sleeved around the corresponding two lug clamping portions (305242) to realize fixation between the two lugs (30543) and the lug clamping portions (305242). An operator can pull the two lugs (30543) to remove the cyclone filter assembly (305) from the cover body (306), which facilitates the user applying force to the cyclone filter assembly (305).

[0182] In some embodiments, as illustrated in FIG. 27, the cover body (306) further includes an upper cover (3065). The upper cover (3065) is fastened to the upper part of the main body (3061) to achieve the effect of shielding the locking structure and uneven structure of the main body (3061) and to achieve the aesthetic effect of the waste storage box (300). Additionally, as illustrated in FIG. 27, the upper cover (3065) is provided with a groove (30651) at a position corresponding to a lug (30543), and when the cyclone filter assembly (305) is installed on the cover body (306), the lug (30543) is positioned in the corresponding groove (30651), and the arrangement of the groove (30651) can achieve a good avoidance effect for the lug (30543). Additionally, when the cyclone filter assembly (305) is installed on the cover body (306), the upper surface of the lug (30543) is positioned on the same plane as the upper surface of the top cover (3065), thereby realizing that the upper part of the waste storage box (300) is flat and has an attractive appearance. In addition, the side of the lug (30543) is arranged at a distance from the side wall of the groove (30651) along the horizontal direction, and the bottom surface of the lug (30543) is arranged at a distance along the vertical direction from the bottom surface of the groove (30651), which facilitates the operator's reach through the above gap and allows the user to grasp the lug (30543).

[0183] In some embodiments, as illustrated in FIG. 19, FIG. 30, FIG. 31 and FIG. 32, the top cover (3065) includes a first top surface (30652). The first top surface (30652) is provided at a preset angle with respect to a horizontal plane, the bottom surface of the connecting portion (30542) is provided at a preset angle with respect to the horizontal plane, and the top portion of the main body (3061) is provided at a preset angle with respect to the horizontal plane. The angle between the first top surface (30652) and the horizontal plane is a preset first angle, the angle between the bottom surface of the connecting portion (30542) and the horizontal plane of the connecting portion (30542) is a preset second angle, and the angle between the top portion of the main body (3061) and the horizontal plane of the main body (3061) is a third preset angle. When the upper part of the main body (3061) contacts the bottom surface of the connecting part (30542), the first upper surface (30652) is placed on the same plane as the second upper surface (30541), and the arrangement of the structure serves to prevent the problem of the cyclone filter assembly (305) being installed in the opposite direction relative to the cover body (306). When the cyclone filter assembly (305) is installed on the cover body (306) by rotating it 180 degrees along the horizontal direction, the first upper surface (30652) and the second upper surface (30541) can be arranged at a narrow angle and not placed on a plane, so that the operator can easily know that the cyclone filter assembly (305) is installed in the opposite direction.

[0184] In some embodiments, as illustrated in FIGS. 19, 20, 27, and 32, a dust discharge port (30613) located below a connecting tube (3051) is provided at the bottom of the main body (3061). The cover body (306) further includes a dust accumulation barrel (3066) connected to an adapter tube (3023), the dust accumulation barrel (3066) is located below the dust discharge port (30613), and a dust ventilation inlet (30661) is provided at the top of the dust accumulation barrel (3066). When the main body (3061) is fitted into the box body (301), the dust discharge port (30613) and the dust inlet port (30661) are arranged in opposite directions so that dust (d) inside the receiving cavity (3064) passes sequentially through the dust discharge port (30613) and the dust inlet port (30661), enters the dust accumulation barrel (3066), and the dust accumulation barrel (3066) can realize the storage of dust (d). When the operator removes the cover body (306) from the box body (301), the operator can grasp the dust accumulation barrel (3066) with their hand and obtain the effect of removing the dust accumulation barrel (3066) and the adapter tube (3023) together from the box body (301), which facilitates cleaning and seating of the dust accumulation barrel (3066), adapter tube (3023), and filter mechanism (307) by the user. In some embodiments, as shown in FIGS. 19 and 20, the distance between the top surface of the dust accumulation barrel (3066) along the vertical direction and the opening (308) is within the range of 10 mm to 20 mm, which facilitates the pickup of the dust accumulation barrel. In some embodiments, as shown in FIGS. 25 and 26, the dust accumulation barrel (3066) and the adapter tube (3023) are formed integrally by an injection molding process, thereby simplifying the installation efficiency of the dust accumulation barrel (3066) and the adapter tube (3023).

[0185] In some embodiments, as illustrated in FIG. 19 and FIG. 32, the cover body (306) further includes a filter grille (3067). The filter grille (3067) is positioned in the dust discharge port (30613), and the mixed gas (c) of the receiving cavity (3064) comes into contact with the filter grille (3067), which can realize the separation of more dust (d) from the mixed gas (c) and can improve the separation effect of dust (d) from the cleaning gas (e). In some embodiments, as illustrated in FIG. 32, the filter grille (3067) includes a central baffle plate (30671) and a plurality of connecting rods (30672), and the central baffle plate (30671) is located in the middle of the dust discharge port (30613). Each connecting rod (30672) is connected to the central baffle plate (30671) and the main body (3061), respectively, and a plurality of connecting rods (30672) are provided uniformly at regular intervals around the central baffle plate (30671). The dust (d) shown in FIG. 19 can be introduced into the dust accumulation drum (3066) through the space between two adjacent connecting rods (30672).

[0186] In some embodiments, as illustrated in FIGS. 19 and 20, the main body (3061) also includes a lower plug end (30614) located at a lower position of the main body (3061), and the lower end of the lower plug end (30614) is provided with a dust discharge port (30613), and the lower end of the lower plug end (30614) is socket-coupled to a dust accumulation barrel (3066) through a dust inlet (30661). The coordination between the lower plug end (30614) and the dust inlet (30661) can realize a fast and accurate alignment plug effect between the air passage of the cyclone filter mechanism (3053) and the dust inlet (30661). The cooperation between the lower plug end (30614) and the dust inlet (30661) can realize a fast and accurate alignment effect between the air passage of the cyclone filter mechanism (3053) and the dust inlet (30661). In some embodiments, as shown in FIGS. 19 and 20, the cross-sectional area of ​​the lower socket end (30614) gradually decreases from the top to the bottom, and the lower socket end (30614) has any convergence effect on dust (d) and collects dust (d) in the dust accumulation barrel (3066), increasing the likelihood that dust (d) will enter the dust accumulation barrel (3066) and preventing the dust discharge port (30613) from being blocked by dust (d).

[0187] In some embodiments, as illustrated in FIGS. 19, 20, and 25, the cover body (306) further includes a sealing structure (3068). The sealing structure (3068) is positioned at the dust inlet (30661), and when the lower plug end (30614) is socket-coupled to the dust inlet (30661), the sealing structure (3068) is provided to seal and contact the periphery of the lower plug end (30614). The arrangement of the sealing structure (3068) can prevent the mixed gas (c) discharged from the dirt outlet from entering the dust accumulation barrel (3066) through the gap between the lower plug end (30614) and the dust accumulation barrel (3066), prevent the mixed gas (c) from stirring the dust (d) inside the dust accumulation barrel (3066), and prevent the dust (d) from being lifted up for discharge and entering the air outlet (30511), thereby ensuring that the air outlet (30511) discharges the cleaning gas (e).

[0188] In some embodiments, as illustrated in FIGS. 19 and 20, the cover body (306) further includes a second shielding plate (3069). The second shielding plate (3069) is connected to the main body (3061), and the second shielding plate (3069) is positioned along the vertical direction between the lower end of the connecting pipe (3051) and the dust discharge port (30613). The arrangement of the second shielding plate (3069) can prevent the airflow inside the duct of the cyclone filter mechanism (3053) from stirring up the dust (d) in the dust accumulation drum (3066) and preventing the dust (d) from being discharged after entering the storage box (300). The airflow of the second shielding plate (3069) prevents the airflow within the duct of the cyclone filter mechanism (3053) from stirring up the dust (d) within the dust accumulation barrel (3066), thereby preventing the dust (d) from being discharged from the dirt storage box (300) after it has entered the cyclone filter mechanism (3053). Specifically, since dust (d) may accumulate at the location where the second shielding plate (3069) is connected to the central baffle plate and block the dust discharge port (30613), the second shielding plate (3069) is detachably connected to the air duct of the cyclone filter mechanism (3053), allowing the user to easily clean the dust accumulated at the connection location between the second shielding plate (3069) and the central baffle plate (30671), ensuring the smooth operation of the dust discharge port (30613) and realizing an excellent recirculation effect of the dust accumulation barrel (3066) for the dust (d). In some embodiments, as shown in FIGS. 19 and 20, the second shielding plate (3069) and the central baffle plate (30671) are detachably connected by screws, so that the user can quickly disassemble and reassemble the second shielding plate (3069) and the central baffle plate (30671). In other embodiments, the screws may be replaced with pins, clamping structures, etc.

[0189] In some embodiments, as illustrated in FIGS. 19 and 20, the longitudinal cross-section of the second shielding plate (3069) forms an upwardly convex curve shape (i.e., a curve shape that rises upward). When the horizontal protruding area is the same, the surface area of ​​the second shielding plate (3069) in this embodiment is large, and the probability of the second shielding plate (3069) coming into contact with the mixed gas (c) entering the air duct of the cyclone filter mechanism (3053) is high. By increasing the number of times solid particles inside the mixed gas (c) come into contact with the mixed gas (c), the separation of a large amount of dust (d) in the mixed gas (c) and the cleaning gas (e) can be realized, thereby removing a large amount of dust (d) and preventing the dust (d) from being discharged from the air outlet (5111).

[0190] In some embodiments, as illustrated in FIGS. 19, 20 and 25, the waste storage box (300) further includes a filter mechanism (307) disposed inside the box (301). The filter mechanism (307) is disposed along a vertical direction [i.e., the longitudinal direction of the device body (1)] between the waste outlet (3021) and the bottom surface (303), and a mixed liquid (a) flows through the filter mechanism (307), and dry waste (f) in the mixed liquid (a) remains in the filter mechanism (307). Wet waste (b) in the mixed liquid (a) flows into the space between the filter mechanism (307) and the bottom surface (303), and the filter mechanism (307) can separate the dry waste (f) and the wet waste (b) from the mixed liquid (a), thereby facilitating a user to thoroughly clean the storage box (300) and realizing a third filtration process of the storage box (300).

[0191] In some embodiments, as shown in FIGS. 19 and 20, the filter mechanism (307) is positioned between the bottom surface (303) of the box body (301) and the cyclone filter assembly (305), so that the filter mechanism (307) can also have a certain barrier effect on the wet waste (b) stored below the filter mechanism (307), thereby preventing the wet waste (b) from splashing to the air inlet (3062) location due to vibration of the storage box (300), preventing water from entering the HEPA and motor, and preventing short circuit of the motor.

[0192] A cleaning device equipped with a dirt storage box (300) (such as the cleaning device (100) of FIGS. 1 to 7) can simultaneously realize three filter processes, and a consumer can realize true multi-purpose by purchasing only one cleaning device (100) and cleaning in various environments, and the consumer does not need to alternate between multiple cleaning devices with different functions or other cleaning devices, and the operation of the cleaning device equipped with the dirt storage box (300) is simple and convenient.

[0193] In some embodiments, as illustrated in FIG. 19, the waste outlet (3021) may be provided on the side of the waste pipe (302) and opposite to the inner wall of the box body (301), and a portion of the dry waste (f) is retained on the inner wall of the box body (301) while the mixed liquid (a) flows from the waste outlet (3021) along the inner wall of the box body (301), thereby further enhancing the separation effect between the dry waste (f) of the mixed liquid (a) and the wet waste (b) of the mixed liquid (a). When the dry waste (f) adheres to the inner wall of the box body (301) and dries naturally to some extent, the dry waste (f) can fall from the inner wall of the box body (301) to the filter mechanism (307).

[0194] In some embodiments, as illustrated in FIGS. 25 and 27, an adapter tube (3023) is connected to a filter mechanism (307), so that when an operator removes the cover body (306) from the box body (301), the operator receiving the dust accumulation barrel (3066) can remove the dust accumulation barrel (3066) and the adapter tube (3023) together from the box body (301), thereby facilitating the operator to clean the dust accumulation barrel (3066), the adapter tube (3023), and the filter mechanism (307) with a large cleaning effect. Accordingly, there is no need to arrange a long rod connected to the filter mechanism (307), so the structure of the dirt storage box (300) is simplified.

[0195] In some embodiments, as illustrated in FIGS. 25 and 27, the adapter tube (3023) is pivotally connected to the filter mechanism (307), and the operator holds the adapter tube (3023) with their hand and rotates the filter mechanism (307) relative to the adapter tube (3023) so that the axis of the adapter tube (3023) is aligned at 90 degrees relative to the axis of the filter mechanism (307) and a portion of the adapter tube (3023) protrudes outward from the periphery of the filter mechanism (307). Since the adapter tube (3023) is relatively clean, when the operator cleans dry debris (f) inside the filter mechanism (307), the inner surface of the filter mechanism (307) faces downward, and the operator holds the portion of the adapter tube (3023) protruding outward from the circumference of the filter mechanism (307) with their hand so that the dry debris (f) inside the filter mechanism (307) falling along the vertical direction does not dirty the user's hand.

[0196] In some embodiments, the structure of the filter mechanism (307) is illustrated in conjunction with FIGS. 19, 25, and 27, and as illustrated in FIGS. 19, 25, and 27, the filter mechanism (307) includes a connecting rod (3071) and a filter basket (3072). The connecting rod (3071) is pivotally connected to an adapter tube (3023), and the filter basket (3072) is connected to the connecting rod (3071). The filter basket (3072) is provided with a filter hole, and dry waste (f) flowing into the filter basket is stored in the filter basket (3072). Since the receiving cavity inside the filter basket (3072) is relatively large and can store a large amount of dry waste (f), the frequency of cleaning of the filter mechanism (307) by the user can be reduced, and the continuous operating time of the cleaning device (100) and the area of ​​the operable cleaning area can be increased.

[0197] In some embodiments, the structure of the filter basket (3072) is illustrated in FIGS. 19, 25 and 27, and as illustrated in FIGS. 19, 25 and 27, the filter basket (3072) includes a support frame (30721) and a filter mesh (30722). A bearing port (30723) is provided at the upper end of the support frame (30721), and an installation port (30724) is provided on the circumferential side of the support frame (30721), and a plurality of first filter holes (30725) are provided in the filter mesh (30722), and the filter mesh (30722) is blocked at the installation port (30724). Since there are many different environments in which the cleaning device (100) is applied, such as cleaning large volumes of dry waste (f) like shredded paper and hair, and cleaning muddy water containing a lot of dust, the operator can select the size of the first filter hole (4221) of the filter mesh (30722) according to the various situations, thereby matching the various situations and improving the versatility of the waste storage box (300). In some embodiments, the filter mesh (30722) may be the filter mesh (213) shown in FIG. 10, or it may be a component having a structure similar to the filter mesh (213) or realizing the same function.

[0198] In some embodiments, as illustrated in FIGS. 19, 25, and 27, by providing a filter mesh (30722) protruding outward, the storage space inside the filter basket (3072) can be increased, thereby enabling the storage and recirculation of a large amount of dry waste in the filter basket (3072). In some embodiments, the filter mesh (30722) may be made of a metal plate or a filter cloth. A filter cloth can filter small dust particles, and a metal plate has relatively high strength and hardness, which can effectively improve the lifespan of the filter mesh (30722). Additionally, the surface area of ​​the convex filter mesh (30722) installed in the same area installation port (30724) is large, and the number of first filter holes (30725) in the convex filter mesh (30722) is large, so the efficiency of separating dry waste (f) and wet waste (b) in the mixed liquid (a) can be increased.

[0199] In some embodiments, the structure of the support frame is illustrated in FIGS. 25 and 27, and as illustrated in FIGS. 25 and 27, the support frame (30721) includes a bulkhead plate (30726) and an annular periphery plate (30727). The bulkhead plate (30726) is provided with a plurality of second filter holes (30728). The annular periphery plate (30727) is connected to the bulkhead plate (30726) to form a receiving space with the bulkhead plate (30726). The annular periphery plate (30727) includes a plurality of installation ports (30724) provided spaced apart along the circumferential direction. The filter mesh (30722) has ends connected to form a ring-shaped structure, and a portion of the outer surface of the filter mesh (30722) contacts the inner surface of the annular periphery plate (30727). Blocking of multiple installation ports (30724) can be achieved by a single filter mesh (30722), which can improve rapid assembly of the filter basket (3072) by the user and improve the efficiency of disassembly and assembly of the filter basket (3072). In some embodiments, the baffle plate (30726) may be the baffle plate (203) shown in FIG. 10, or a component having a structure similar to the baffle plate (203) or realizing the same function. In some embodiments, the annular periphery plate (30727) may be the frame (212) shown in FIG. 10, or a component having a structure similar to the frame (212) or realizing the same function. In some embodiments, the combination of the annular periphery plate (30727) and the frame (212) may be referred to as a baffle wall (e.g., the baffle wall (211) illustrated in FIG. 10).

[0200] In some embodiments, as shown in FIG. 22, the distance between the partition (30726) and the bottom surface (303) of the box body (301) is L5, the height of the box body (301) is H, and the L5 / H ratio is 1 / 3 to 1 / 2. That is, 1 / 3 to 1 / 2 of the volume of the box body (301) is configured to store wet waste (b), so the cleaning device (100) can store a large amount of wet waste (b).

[0201] In some embodiments, as shown in FIG. 25, the height of the annular side periphery plate (30727) may be 20 mm to 50 mm. Compared to a support frame (30721) having only a partition (30726), the annular side periphery plate (30727) of the filter basket (3072) has a certain height, thereby realizing the effect of increasing the storage space for dry waste (dry waste (f) shown in FIG. 19), and thereby, the filter basket (3072) can realize the effect of storing more dry waste.

[0202] In some embodiments, as shown in FIGS. 20 and FIGS. 25, the second filter hole (30728) is an elongated hole, and a plurality of second filter holes (30728) are uniformly arranged around the centerline of the partition plate (30726), thereby enabling a uniform downward flow of wet waste (wet waste (b) shown in FIG. 19) at each location of the partition plate (30726), and by preventing the second filter hole (30728) from being clogged due to an uneven distribution, the solid-liquid separation efficiency of the filter basket (3072) is improved.

[0203] In some embodiments, as shown in FIGS. 20 and 25, a through hole (30729) is provided in the center of the spacer (30726), and the tube body (3022) passes through the through hole (30729) and is connected to the adapter tube (3023) so that the filter basket (3072) is not distorted within the box (301) when the cleaning device (100) is tilted or laid flat. In some embodiments, the through hole (30729) may be the installation hole (214) shown in FIG. 10, or may be a component of the waste storage box (300) that has a structure similar to the installation hole (214) or can perform the same function, or can perform the same function as the installation hole (214) of the waste storage box (4) shown in FIG. 8.

[0204] Additionally, the through hole (30729) extends upward to form a conduit (30730), and the tube body (3022) is fitted into the conduit (30730), and the outer surface of the tube body (3022) is pressed against the inner wall of the conduit (30730), which can improve the contact area between the filter basket (3072) and the tube body (3022) and further prevent the filter basket (3072) from being distorted in the box body (301). In some embodiments, the conduit (30730) may be an annular baffle (215) shown in FIG. 10, or may include a component having a structure similar to an annular baffle (215) or realizing the same function.

[0205] In some embodiments, as shown in FIGS. 19, 20, and 25, the outer surface of the tube body (3022) and the inner wall of the conduit (30730) are made to form a press fit, thereby realizing an excellent fixing effect between the filter basket (3072) and the tube body (3022), preventing the filter basket (3072) from sliding toward the bottom surface (303) of the box body (301) and preventing the filter basket (3072) from coming into contact again with the wet waste (b) that has filtered out the dry waste (f), thereby ensuring that the dry waste (f) and the wet waste (b) are arranged independently of each other. Specifically, the diameter of the tube body (3022) gradually decreases from the bottom to the top, and the outer diameter of the tube body (3022) at the middle position is equal to the diameter of the inner hole of the conduit (30730), thereby ensuring that the filter basket (3072) is secured to the tube body (3022) at the middle position of the tube body (3022). Additionally, the diameter of the upper part of the tube body (3022) is smaller than the diameter of the inner bore of the conduit (30730), which also facilitates the operator installing the filter basket (3072) on the tube body (3022).

[0206] In some embodiments, the partition plate (30726) is provided to slope downward from the through hole (30729) to the edge of the partition plate (30726), which causes the mixed liquid to tend to flow downward, thereby improving the solid-liquid separation effect of the filter basket (3072) and preventing the liquid from settling on the partition plate (30726). Additionally, if the horizontal surface protrusion area of ​​the partition plate (30726) is sufficient, the structure can increase the total surface area of ​​the partition plate (30726) and increase the total area of ​​the plurality of second filter holes (30728), thereby improving the separation efficiency of dry waste (f) and wet waste (b).

[0207] In some embodiments, as shown in FIG. 19, the upper edge of the annular side periphery plate (30727) is in sealing contact with the inner surface of the box body (301). Thus, large particles or a large amount of dry waste (f) first cannot pass through the gap between the upper edge of the annular side periphery plate (30727) and the inner surface of the box body (301), and after undergoing the separation action of the filter mechanism (307), large particles or a large amount of dry waste (f) remain in the filter mechanism (307), preventing large particles or a large amount of dry waste (f) from entering the wet waste (b) of the filter mechanism (307). In addition, wet waste (b) between the filter mechanism (307) and the bottom surface (303) cannot pass through the gap between the upper edge of the annular periphery plate (30727) and the inner surface of the box body (301), thereby completely preventing the possibility of wet waste (b) between the filter mechanism (307) and the bottom surface (303) entering the filter mechanism (307) due to vibration. Of course, since the upper edge of the annular periphery plate (30727) is in sealing contact with the inner surface of the box body (301), relative displacement between the filter basket (3072) and the box body (301) is prevented even when the waste storage box (300) vibrates.

[0208] In some embodiments, as shown in FIG. 19, the cross-sectional area of ​​the annular side periphery plate (30727) gradually decreases from the top to the bottom, so that there is a gap between the filter mesh (30722) and the inner periphery of the box body (301), and wet waste (b) is introduced into the space between the filter mechanism (307) and the bottom surface (303) through the first filtration opening (4221) on the filter mesh (30722), thereby improving the separation efficiency of the mixed liquid (a) and separating dry waste (f) and wet waste (b).

[0209] For ease of understanding, the operating principle of the waste storage box (300) according to three operating conditions will be explained in relation to FIG. 19.

[0210] In some embodiments, as illustrated in FIG. 19, when a cleaning device (e.g., cleaning device (100) of FIG. 1 to 7) equipped with a dirt storage box (300) performs only vacuum cleaning, the fluid (M) contains only dust and air, some of the dust in the fluid (M) discharged from the dirt outlet (3021) moves downward and falls into the filter basket (3072), and other dust mixes with air to form a mixture of cleaning gas and enters the cyclone filter assembly (305) through the air inlet (3062), the dust (d) remains in the dust accumulation drum (3066), and the cleaning gas (e) is discharged from the cyclone filter assembly (305).

[0211] In some embodiments, as illustrated in FIG. 19, when a cleaning device (e.g., cleaning device (100) of FIG. 1 to 7) equipped with a dirt storage box (300) performs only water suction conditions, the fluid (M) contains only water and air, and the water in the fluid (M) discharged from the dirt outlet (3021) moves downward and is stored at the bottom of the box (301), thereby enabling the recovery of dirt. The air mixed in the fluid (M) passes through the air inlet (3062) and the cyclone filter assembly (305) in sequence and is discharged from the cyclone filter assembly (305).

[0212] In some embodiments, as illustrated in FIG. 19, when a cleaning device (e.g., cleaning device (100) of FIG. 1 to 7) equipped with a dirt storage box (300) performs a dust and water mixture operating condition, the fluid (M) is separated into a mixed liquid (a) and a mixed gas (c) at the dirt outlet (3021), and the mixed liquid (a) tends to move generally downward. The mixed liquid (a) is separated into dry dirt (f) and wet dirt (b) (or wet dirt (or liquid dirt)), the dry dirt (f) remains in the filter mechanism (307), and the wet dirt (b) enters the bottom of the filter mechanism (307). The mixed gas (c) is separated into cleaning gas (e) and dust (d) in the cyclone filter assembly (305), the dust (d) remains in the dust accumulation barrel (3066), and the cleaning gas (e) is discharged from the cyclone filter assembly (305) through the air outlet (30511).

[0213] In some embodiments, the cover body (306) of the dirt storage box (300) may not be provided with a dust accumulation barrel (3066). Specifically, as shown in FIG. 33, the cover body (306) may include a first shielding plate (30615). A shielding plate (30615) pivotably connected to a main body (3061) is inserted into the box body (301), and the upper end of the tube body (3022) comes into contact with the first shielding plate, so that the first shielding plate (30615) seals the dust discharge port (30613), and dust (e.g., dust (d) shown in FIG. 19) can be stored between the main body (3061) and the first shielding plate (30615). When the cover body (306) is removed from the box body (301), the first blocking plate (30615) rotates by gravity with respect to the duct of the cyclone filter mechanism (3053), thereby opening the dust discharge port (30613), and the dust in the dust storage space can automatically fall into the filter basket (3072) below through the dust discharge port (30613), and the operator can clean dust and dry debris (e.g., dry debris (f) of FIG. 19) at the same time when cleaning the filter basket (3072).

[0214] In some embodiments, the first shielding plate (30615) may be connected to the main body (3061) by a pivot shaft. A torsion spring is sleeved in the pivot shaft, and both ends of the torsion spring are offset from the first shielding plate (30615) and the main body (3061), respectively, so that when the cover body (306) is removed from the box body (301), the first shielding plate (30615) automatically opens the dust discharge port (30613) by means of the elastic restoring force of the torsion spring, thereby enabling a large amount of dust to fall into the filter basket (3072). In some embodiments, when the torsion spring is in its natural state, the first shielding plate (30615) is at a 60-degree angle to the plane where the dust discharge port (30613) is located, so when the main body (3061) is inserted into the box body (301), the tube body (3022) can smoothly push the first shielding plate (30615) to block the dust discharge port (30613).

[0215] In some embodiments, as shown in FIG. 33, the processing and forming efficiency of the waste pipe (302) can be improved by integrally molding the waste pipe (302).

[0216] In some embodiments, as shown in FIG. 33, the arrangement of dust accumulation barrels (3066) in the cover body (306) is omitted, thereby increasing the available space inside the box body (301). The baffle plates (3063) can be arranged in a ring shape to surround the periphery of the waste pipe (302) near the waste outlet (3021), so that the area of ​​the baffle plates (3063) around the waste pipe (302) can be increased, and a large amount of dry waste in the mixed liquid (e.g., the mixed liquid shown in FIG. 19) can remain on the solid surface of the baffle plates (3063), thereby obtaining an excellent separation effect for separating dry waste from wet waste (e.g., wet waste (b) shown in FIG. 19) in the mixed liquid.

[0217] In some embodiments, the structure of the filter mechanism (307) illustrated in FIG. 34 may differ slightly from the filter mechanism (307) of another embodiment of the present disclosure (e.g., the filter mechanism (307) illustrated in FIG. 19), and the main difference between the two is that, as illustrated in FIG. 33 and FIG. 34, the filter mechanism (307) may include a lifting handle (3073) and a filter basket (3072). The filter basket (3072) is connected to the lifting handle (3073), so that the vertical distance between the upper surface of the handle (3073) and the opening (308) is within the range of 10 mm to 20 mm. When removing the cover body (306) from the box body (301), the user can remove the filter basket (3072) from the box body (301) by receiving the handle (3073), and the structure of the filter mechanism (307) is simple and easy for the user to operate.

[0218] In some embodiments, as illustrated in FIG. 34, the handle (3073) includes a connecting rod (30731) and a handle portion (30732). One end of the connecting rod (30731) is connected to a filter basket (3072). The handle portion (30732) is connected to the other end of the connecting rod (30731). The width of the handle (3073) is greater than the width of the connecting rod (30731), and the handle portion (30732) is provided to facilitate the operator's reception and application of force. Specifically, the handle (3073) includes a connecting plate (30733), a first side plate (30734), a second side plate (30735), and a third side plate (30736). The connecting plate (30733) is connected to the other end of the connecting rod (30731). The first side plate (30734), the second side plate (30735), and the third side plate (30736) are all positioned on one side perpendicular to the connecting plate (30733), the first side plate (30735), and the third side plate (30736). The first side plate (30734) and the third side plate (30736) are connected to both sides of the second side plate (30735). The gap between the first side plate (30734) and the third side plate (30736) gradually increases from the bottom to the top, and the inverted trapezoidal handle (3073) is convenient for the operator to grip.

[0219] In some embodiments, as illustrated in FIG. 34, the filter mechanism (307) further includes a reinforcing plate reinforcement (30739). The reinforcing plate reinforcement (30739) is connected between the connecting rod (30731) and the handle (3073) to improve and harden the overall strength of the filter mechanism (307), thereby preventing deformation problems that occur during repeated pickup of the filter mechanism (307) and improving the lifespan of the filter mechanism (307).

[0220] In some embodiments, to improve the gripping effect on the operator's handle portion (30732) and to prevent slipping between the hand and the handle portion (30732), an anti-slip pattern is arranged on the outer surface of the first side plate (30734), the second side plate (30735), and the third side plate (30736). In some embodiments, as shown in FIG. 34, a plurality of ventilation holes (30737) are provided spaced apart in the first side plate (30734), the second side plate (30735), and the third side plate (30736), and an anti-slip pattern is arranged between the ventilation holes (30737).

[0221] In some embodiments, as shown in FIG. 33, the handle portion (30732) is located below the air inlet (3062) and opposite the air inlet (3062). The mixed gas (e.g., mixed gas (c) shown in FIG. 19) enters the air inlet (3062) through the ventilation hole (30737) and then enters the cyclone channel to exert a cyclone effect, and the mixed gas collides with the first side plate (30734), the second side plate (30735), and the third side plate (30736) before entering the air inlet (3062). Some of the solid particles in the mixed gas free-fall to the filter mechanism (307) during the collision process, which can create a cleaning gas (e.g., cleaning gas (e) shown in FIG. 19), which is subsequently discharged cleanly from the air inlet (3062).

[0222] In some embodiments, as shown in FIGS. 33 and 34, a backflow prevention structure (30738) is installed in the partition (30726) so that dirt flowing from the dirt pipe (302) into the upper space of the box body (301) enters the lower space for storage through at least the backflow prevention structure (30738), thereby preventing dirt in the lower space from flowing into the upper space through the backflow prevention structure (30738). In some embodiments, the backflow prevention structure (30738) may be the backflow prevention structure (230) described above (e.g., FIG. 8).

[0223] In some embodiments, for a cleaning device (e.g., cleaning device (100) shown in FIGS. 1 to 7) equipped with a dirt storage box (300), when the device body (1) (or dirt storage box (300)) is in a substantially upright position (e.g., an angle of 60 to 90 degrees relative to the horizontal plane, hereinafter referred to as “upright”), dirt is sucked into the dirt pipe (302), flows from the dirt pipe (302) into the upper space, and then flows into the lower space through the backflow prevention structure (30738) and is stored in the lower space. When the device body (1) (or dirt storage box (300)) is tilted significantly (e.g., an angle of 30 degrees or less relative to the horizontal plane, or even about 2 degrees relative to the horizontal plane, hereinafter referred to as “flattening”), the backflow prevention structure (30738) prevents dirt in the lower space from flowing back through the backflow prevention structure (30738) and flowing into the upper space. The backflow prevention structure (30738) prevents dirt from flowing back into the upper space through the backflow prevention structure (30738). The backflow prevention structure (30738) prevents dirt from flowing backward into the upper space through the backflow prevention structure (30738) so that dirt does not enter the motor (e.g., motor (33) or motor (34)) of the cleaning device (100), and the motor does not stop, and the cleaning device (100) can still be cleaned normally. As a result, the cleaning device (100) equipped with a dirt storage box (300) can not only be used with the device body (1) in an upright position, but can also be used with the device body (1) tilted sharply or laid flat, thereby greatly facilitating user use.

[0224] FIG. 35 is a perspective view illustrating a floor brush according to some embodiments of the present disclosure. In some embodiments, the floor brush (2) illustrated in FIG. 1 to 7 may specifically be the floor brush (400) illustrated in FIG. 35. Hereinafter, a floor brush according to an embodiment of the present disclosure will be described in detail with reference to the attached drawings.

[0225] As illustrated in FIG. 35, the floor brush (400) may include a working portion (410) and a connecting portion (420). The floor brush (400) has front and rear portions facing each other in the width direction (e.g., the W direction illustrated in FIG. 35). A connecting portion (420) is provided at the rear of the working portion (410), and the connecting portion (420) is connected to the device body (1). In some embodiments, the working portion (410) and the connecting portion (420) may be a single structure or independent structures. In some embodiments, the working portion (410) includes a floor brush body (430) and a cleaning fluid box (440) (i.e., the aforementioned cleaning fluid box (50)) that is detachably installed on the floor brush body (430). The floor brush body (430) comes into direct contact with the surface to be cleaned (e.g., the floor) to clean debris on the surface to be cleaned. The floor brush body (430) is provided with a suction port (434) for sucking up debris. The cleaning fluid box (440) is part of the cleaning fluid supply assembly and stores cleaning fluids such as water, cleaning agent, and conditioner. In usage situations where water needs to be sprayed onto a surface to be cleaned, the cleaning fluid is pumped from the cleaning fluid box (440) to the surface to be cleaned.

[0226] In some embodiments, the cleaning fluid box (440) may be made of a transparent or opaque material so that a user can determine the amount of cleaning fluid within the cleaning fluid box (440). In some embodiments, the cleaning fluid box (440) may be a one-piece molded structure. In some embodiments, the transparent material may include, but is not limited to, one or more of polymethyl methacrylate, polystyrene, polycarbonate, styrene acrylonitrile, ABS plastic, etc. In some embodiments, the cleaning fluid box (440) may also include a box body structure comprising a plurality of elements. For example, the cleaning fluid box (440) may include a first housing and a second housing arranged sequentially from top to bottom. The bottom of the first housing and the top of the second housing are connected to form a cleaning fluid box (440) having a cavity inside. In some embodiments, the first housing and the second housing may be connected through one or more of adhesive connections, clamping connections, welding connections, etc. For example, the first housing and the second housing may be joined by a UV-curing adhesive (UV adhesive). In some embodiments, the materials of the first housing and the second housing may be the same or different. For example, in order to increase the weight of the cleaning fluid box (440) to further increase the pressure of the floor brush (1) on the cleaning surface and improve the cleaning effect, in some embodiments, the first housing may be made of a material such as polymethyl methacrylate, polystyrene, polycarbonate, styrene acrylonitrile, or ABS plastic, and the second housing may be made of a material such as glass, ceramic, or metal (e.g., stainless steel). In some embodiments, the shape of the cleaning fluid box (440) is approximated as a rectangular structure, a trapezoidal structure, etc.

[0227] When the cleaning fluid box (440) is filled with cleaning fluid, the protrusion of the center of gravity along the height direction of the cleaning fluid box (440) is located in the central region of the cleaning fluid box (440). It should be noted that the center of gravity of the cleaning fluid box (440) moves up and down along the height direction of the cleaning fluid box (440) depending on the amount of cleaning fluid. For example, if the cleaning fluid box (440) has a regular structure (e.g., a roughly rectangular structure), the center of gravity of the cleaning fluid box (440) becomes the geometric center of the cleaning fluid box (440) when the amount of cleaning fluid in the cleaning fluid box (440) is maximum (i.e., when the cleaning fluid box (440) is filled with cleaning fluid). As another example, if the amount of cleaning fluid in the cleaning fluid box (440) is less than the capacity of the cleaning fluid box (440), the center of gravity of the cleaning fluid box (440) is located below the geometric center of the cleaning fluid box (440). Therefore, if an outlet is provided at the bottom of the cleaning fluid box (440), the cleaning fluid can be more easily discharged from the outlet of the cleaning fluid box (440) by gravity. Additionally, if the cleaning fluid box (440) has an irregular structure, for example, if the cleaning fluid box (440) has a concave or protruding area relative to its side wall, the protrusion of the center of gravity of the cleaning fluid box (440) along the height direction is located in the middle area of ​​the cleaning fluid box (440), so that when a user takes out the cleaning fluid box (440) containing the cleaning fluid, the center of gravity of the cleaning fluid box (440) is not excessively offset, thereby making it easier for the user to grip it.

[0228] In some embodiments, the outlet of the cleaning fluid box (440) may be located in the bottom center area of ​​the cleaning fluid box (440) to facilitate the outflow of the cleaning fluid. In some embodiments, the outlet of the cleaning fluid box (440) may also be located at other locations of the cleaning fluid box (440). For example, the outlet of the cleaning fluid box (440) may be located on the side of the cleaning fluid box (440) to facilitate the placement of the pipe (e.g., the first pipe). The outlet of the cleaning fluid box (440) may be located on the side of the cleaning fluid box (440) away from the rod (e.g., the rod (11) in FIG. 6) to reduce the length of the pipe.

[0229] In some embodiments, the cleaning fluid in the cleaning fluid box (440) may be sprayed through a cleaning fluid supply assembly (e.g., a nozzle (460) and a pump (461) shown in FIG. 38), and the pump (461) is configured to pump the cleaning fluid from the cleaning fluid box (440) to the nozzle (460), and the nozzle (460) serves as the output end of the cleaning fluid supply assembly to spray the cleaning fluid onto the floor to be cleaned, thereby cleaning and / or controlling the floor.

[0230] In some embodiments, the cleaning fluid box (440) may include a water inlet (4401) for injecting a cleaning fluid or an aqueous solution, and the water inlet (4401) may be arranged on the top wall of the cleaning fluid box (440), and the water inlet (4401) extends through the top wall of the cleaning fluid box (440) and communicates with a cavity within the cleaning fluid box (440). In some embodiments, an orifice plug may be provided at the water inlet (4401), which fits with the water inlet (4401). For example, two may be connected by fitting through a screw connection, an interference fit, a plug-in connection, etc. In some embodiments, the cleaning fluid box (440) may include one or more cavities. For example, one cavity may be included in the cleaning fluid box (440), and the cleaning fluid is located within the cavity. As another example, the cleaning fluid box (440) may include a first cavity and a second cavity. The first cavity is connected to the second cavity, the first cavity is configured to contain an aqueous solution, and the second cavity is configured to contain a cleaning agent, wherein the cleaning agent can be dissolved or diluted by injecting the aqueous solution into the first cavity, thereby forming a cleaning fluid.

[0231] In some embodiments, the cleaning fluid box (440) may include a first gripping portion (4402) that a user can grasp with their hand. The first gripping portion (4402) is positioned on the top wall of the cleaning fluid box (440). In some embodiments, the first gripping portion (4402) may be a fastener member. In some embodiments, the first gripping portion (4402) may include a first recess that is concave downward with respect to the top of the cleaning fluid box (440). The first recess forms a handle-like structure with the top wall of the cleaning fluid box (440) above the first recess, allowing the user to pick up the cleaning fluid box (440). In some embodiments, the cleaning fluid box (440) may further include a second gripping portion (4403), and the second gripping portion (11204) is positioned on the side wall of the cleaning fluid box (440) facing the connection portion (420). For example, the second gripping portion (4403) may be a groove area of ​​the side wall of the cleaning fluid box (440) facing the connecting portion (420). In some embodiments, the first gripping portion 4402 and / or the second gripping portion (4403) may be located in the central area of ​​the cleaning fluid box (440). When the cleaning fluid box (440) is filled with water, the center of gravity of the cleaning fluid box (440) is offset from the side away from the groove area, because the bottom of the groove area of ​​the cleaning fluid box (440) requires other components (e.g., the first protrusion (43141) that accommodates the pump (461) described later) so that it aligns with the pump (461), but the center of gravity of the cleaning fluid box (440) is still on the protrusion of the first gripping part (4402) or the second gripping part (4403), so the cleaning fluid box (440) is substantially balanced when the user moves the cleaning fluid box (440) near the device body (1). Additionally, the cleaning fluid box (440) is formed in a roughly dumbbell shape, and the user can grip the cleaning fluid box (440) with the first gripping part (4402) or the second gripping part (11204).For example, the first gripping part (4402) is a latch, and the second gripping part (4403) is roughly in the shape of a groove area so that the user can lift the cleaning fluid box (440) while gripping the dumbbell.

[0232] For convenience of explanation, in the present disclosure, the longitudinal direction in FIG. 35 may be represented as the L direction, the height direction in FIG. 35 as the H direction, and the width direction in FIG. 35 as the W direction.

[0233] By installing a cleaning fluid box (440) on the floor brush body (430), the user can easily operate the device body and clean the space under the bed by holding it with their hand. At the same time, by using the above structure, there is no need to arrange a relatively long cleaning fluid hose, so a relatively fast spraying response can be obtained. In addition, with the above configuration, the overall weight of the floor brush (400) is increased, and the force with which the floor brush (400) presses against the floor is increased, thereby improving the cleaning effect.

[0234] The size of the work portion (410) can be made large so that the work portion is not dragged to areas such as the bed base or corners for cleaning by arranging the cleaning fluid box (440) on the floor brush (400). To solve the above problem, in relation to FIGS. 35, 36 and 37, in some embodiments, the work portion (410) may have a roughly rectangular shape protruding along the height direction (the H direction shown in FIG. 35), and the maximum size (d1) of the work portion (410) may be 270 mm or less along the length direction (the L direction shown in FIG. 35). Compared to other shapes, the roughly rectangular protrusion of the work portion (410) has a wider cleaning range and takes up less space in a single push and pull, and at the same time, the arrangement of the connecting portion (420) and the cleaning fluid box (440) is easy. Additionally, the edge position cleaning efficiency of the work part (410) can be improved by adjusting the maximum size (d1) along the longitudinal direction of the work part (410). If the longitudinal maximum size (d1) of the work part (410) is too small, the cleaning efficiency in the open space is reduced, and in some embodiments, the maximum length of the work part is within the range of 250 mm to 270 mm.

[0235] The working part (410) not only serves as an upstream component for sucking up waste, but also works in cooperation with the connecting part (420) to support the device body (or handle) and other components of the cleaning device, and at the same time serves to install the cleaning fluid box (440). To simultaneously satisfy the stabilizing support role and the installation carrier role of the working part (410), the working part (410) is made to have the smallest possible size. In some embodiments, this can be achieved by adjusting the length or width of the working part (410). In some embodiments, the ratio of the maximum width direction size (d2) to the maximum length direction size (d1) of the working part (410) is within the range of 0.5 to 0.7. It should be noted that the working part (410) serves as a frame structure for the floor brush (400), and the size of the working part (410) can be close to the size of the floor brush (400).

[0236] In order to ensure that the cleaning fluid supply assembly can wet a sufficient area, in some embodiments, the capacity of the cleaning fluid box (440) may be 0.35L to 0.6L. Since the cleaning fluid box (440) has a box body housing, the volume of the box body housing (space to be occupied) must be larger than the capacity of the box body. In some embodiments, the ratio of the capacity of the cleaning fluid box (440) to the volume of the cleaning fluid box (440) is 0.35 or greater. Thus, by pre-setting the capacity of the cleaning fluid box (440), the cleaning fluid box (440) can be limited so that it does not occupy too much space, and the overall compactness of the work part (410) can be increased.

[0237] In some embodiments, the ratio of the volume of the cleaning fluid box (440) to the volume of the work portion (410) may be 0.3 to 0.6. Accordingly, once the length and width of the work portion are determined, the height of the work portion (410) is limited, so that the floor brush (400) can conveniently reach areas with limited height, such as the bottom of a bed or the bottom of a sofa, for cleaning. In some embodiments, the ratio of the maximum height size (d3) to the maximum length size (d1) of the work portion (41) is within the range of 0.25 to 0.55, so that the cleaning performance, convenience, ease of use, and aesthetics of the work portion (410) can be satisfied simultaneously.

[0238] In order to maximize the installation space of the floor brush body (430) and to match the basic shape of the work section (410), in some embodiments, the height-direction protrusion of the cleaning fluid box (440) is approximately rectangular, and the longitudinal maximum size (d4) of the cleaning fluid box (440) is substantially the same as the longitudinal maximum size (d1) of the work section (410). It can be understood that the distance between the two sides of the cleaning fluid box (440) along the longitudinal direction of the floor brush (400) is substantially the same as the distance between the two sides of the floor brush body (430). The circumferential limiting function of the installation housing of the cleaning fluid box (440) is maintained, and the upper structure of the cleaning fluid box (440) can be extended along the longitudinal direction to be substantially the same as the longitudinal maximum size of the work section (410). At the same time, the size of the cleaning fluid box (440) in the height direction and the size of the cleaning fluid box (440) in the width direction can be easily adjusted by designing the size of the cleaning fluid box (440) in the length direction to be as large as possible, thereby making it easy to design the installation location of the component in the work part (410).

[0239] Additionally, it should be noted that the cleaning fluid box (440) may not be square when viewed from above because it must be installed with the necessary restrictive structure and / or avoid other components (e.g., the connecting part (420)). Being substantially rectangular means that the two opposing sides have substantially parallel sections. Also, the protrusion of the working part (410) along the height direction should be understood as being substantially rectangular.

[0240] Additionally, the rear end of the cleaning fluid box (440) may constitute the rear end of at least the partial work part (410). For example, the cleaning fluid box (440) is positioned as far back as possible to prevent the part from being located in front of the floor brush body (430).

[0241] In some embodiments, as illustrated in FIG. 35, the floor brush body (430) may include an installation housing (431), an upper baffle cover (432), and a roller brush (433). The roller brush (433) is rotatably positioned in the front portion of the installation housing (431) to roll and rub the surface to be cleaned, and the upper baffle cover (432) is positioned in the upper portion of the roller brush (433) to cover at least a portion of the roller brush and serve as an installation carrier. Meanwhile, a cleaning fluid box (440) is positioned behind the upper baffle cover (432). According to the above positional arrangement, the structure of the working part (410) can be made more compact, and is highly space-efficient, aesthetically pleasing, and practical.

[0242] In some embodiments, the cleaning fluid box (440) and the upper baffle cover (432) may be provided as a single unit, and when the cleaning fluid is introduced, the cleaning fluid box (440) must be removed together with the upper retaining cap (432).

[0243] In some embodiments, the cleaning fluid box (440) and the upper baffle cover (432) may be arranged separately, and since the cleaning fluid box (440) and the upper baffle cover (432) can be understood as mutually independent components, it is convenient to take out the cleaning fluid box (440) separately to replenish the cleaning fluid, thereby resolving the problem of user inconvenience when the cleaning fluid box (440) and the upper baffle cover (432) are installed as a single unit.

[0244] In order for the working part (410) to smoothly reach the underside of the bed, the top of the working part (410) can be made to have a roughly flat structure so that as many protrusions as possible are not formed on the top of the working part (410). Accordingly, the top surface of the cleaning fluid box (440) and the top surface of the upper baffle cover (432) are roughly horizontal, and the aforementioned top surfaces must all be roughly flat to prevent step differences.

[0245] During the cleaning process, considering that the longitudinal sides of the work section (410) are prone to colliding with obstacles, the impact generated upon collision is reduced. In some embodiments, the upper baffle cover (432) and the cleaning fluid box (440) located on the upper part of the work section (410) are configured with rounded or chamfered edges along both longitudinal sides of the floor brush.

[0246] In relation to FIGS. 35 to 42, in some embodiments, the upper baffle cover (432) is detachably connected to the installation housing (431) to facilitate cleaning, disassembly, and assembly of the roller brush (433). Compared to a method in which the cleaning fluid box (440) and the upper baffle cover (432) are arranged as a single unit, the upper baffle cover is configured such that the cleaning fluid box (440) and the upper baffle cover (432) are arranged separately and detachably connected to the installation housing (431), thereby further optimizing the structure of the working part (410) to closely satisfy the user's usage habits.

[0247] Additionally, it should be noted that if the width of the upper baffle cover (432) is too small, it may be difficult to properly achieve the cleaning and removal effects of the roller brush. Accordingly, in some embodiments, the ratio of the maximum widthwise size (d5) of the cleaning fluid box (440) to the maximum widthwise size (d2) of the work section (410) may be 0.5 to 0.7. The upper baffle cover (432) provides sufficient installation space by limiting the maximum size (e.g., maximum width) of the cleaning fluid box (440) along the widthwise direction.

[0248] As illustrated in conjunction with FIGS. 35, 38, and 39, in some embodiments, the installation housing (431) may include a bottom housing (4311) and a top cover (4312). A brush installation cavity (450) for accommodating a roller brush (433) is formed between the bottom housing (4311) and the top cover (4312). The installation housing (431) of the bottom brush body (430) is composed of a suction port (434) for sucking up debris, and the suction port (434) is located on the front side of the bottom housing (4311) and on the rear side of the brush (433). A bottom brush channel (451) (i.e., the first channel (6) illustrated in FIGS. 2 through 5) is provided in the brush installation cavity (450) so as to be in fluid communication with the suction port (434). During the cleaning process, debris on the surface to be cleaned is moistened by the roller brush (433), sucked in by the suction port (434), and then guided by the floor brush channel (451). The end of the floor brush channel (451) away from the suction port (434) is connected to the second channel (202) of the device body (1) so that the debris can be transferred to the dirt storage box (4) (shown in FIGS. 2 to 5).

[0249] Since the floor brush channel (451) occupies a certain height within the roller brush installation cavity (450), a height limit is required for the cleaning fluid box (440) located in the upper part of the roller brush installation cavity (450), thereby preventing excessive height of the work portion (410). In some embodiments, as illustrated in FIG. 36 and FIG. 43, the ratio of the maximum size (d6) of the cleaning fluid box (440) along the height direction to the maximum size (d3) of the work portion (410) along the height direction may be 0.4 to 0.7.

[0250] As illustrated in relation to FIGS. 38 through 43, in some embodiments, a receiving box (4313) is formed in the upper portion of the top cover (4312), and a cleaning fluid box (440) is disposed inside the receiving box (4313). In some embodiments, the cleaning fluid box (440) is detachably connected to the receiving box (4313). To facilitate the removal or insertion of the cleaning fluid box (440) into the receiving box (4313), in some embodiments, as illustrated in relation to FIGS. 41 and 42, the maximum height size (d6) of the cleaning fluid box (440) may be larger than the height size (d8) of the receiving box (4313) (or also referred to as the depth of the receiving box (4313). Based on the structure of the aforementioned receiving groove (4313), protrusions (4314) are formed on both sides of the top cover (4312) along the longitudinal direction of the bottom brush, and at the same time, both sides of the cleaning fluid box (440) are formed with grooves (4315) capable of receiving the protrusions (4314). Accordingly, the cleaning fluid box (440) may have a shape in which the upper part is slightly longer than the protrusions (4314) and the lower part is slightly shorter. The lower part of the cleaning fluid box (440) is configured to allow for limited installation, and since the upper part is slightly longer, it is advantageous for extending the capacity of the cleaning fluid box (440).

[0251] In some embodiments, a slightly longer portion of the upper part of the cleaning fluid box (440) is a projection (4404) that protrudes along the longitudinal direction of the cleaning fluid box (440) on both sides of the cleaning fluid box (440) relative to the groove (4315). The projection (1126) forms a stepped structure with the groove (4315), and the stepped structure aligns with the projection (4314). In some embodiments, the bottom of the water inlet (4401) of the cleaning fluid box (440) is higher than the stepped structure. That is, the water inlet (4401) of the cleaning fluid box (440) is higher than the connection point between the groove (4315) and the projection (4404). Additionally, the projection (4404) of the cleaning fluid box (440) has a cavity that communicates with the cleaning fluid box (440). That is, since the protrusion (4404) has a hollow internal structure, when the cleaning fluid box (440) is filled with cleaning fluid, the protrusion (4404) of the cleaning fluid box (440) has a space for the cleaning fluid to enter above the groove (4315), thereby securing the capacity of the cleaning fluid box (440). As illustrated in FIG. 40, in some embodiments, the water inlet (4401) of the cleaning fluid box (440) is higher than the stepped structure formed by the protrusion (4404) and the groove (4315), which ensures that the interior of the protrusion (4404) can store the cleaning fluid, thereby increasing the storage space of the cleaning fluid box (440). In some embodiments, the maximum size (d11) of the internal space of the protrusion (4404) along the height direction may be within the range of 10 to 20 mm. For example, the maximum size (d11) of the internal space along the height direction of the protrusion (4404) may be 14 mm. In some embodiments, the size (d12) of the internal space of the protrusion (4404) along the length direction of the floor brush (400) may be 8 to 15 mm. For example, the size (d12) of the internal space corresponding to the protrusion (4404) may be 11 mm.

[0252] If the size of the groove (4315) along the height direction is small, the protrusion (4314) is less restricted by the groove (4315), making the cleaning fluid box (440) prone to shaking. If the size of the depth of the groove (4315) along the height direction is too large, the spatial extension of the cleaning fluid box (440) located in the upper part of the groove (4315) is limited, and thus the meaning of such spatial extension is almost nonexistent. To solve the above problem, as illustrated in FIG. 39 and FIG. 42, in some embodiments, the ratio of the size (d10) of the groove (4315) along the height direction to the maximum size (d6) of the cleaning fluid box (440) along the height direction may be 0.4 to 0.7.

[0253] When the protrusion (4314) is relatively thin and the strength of the protrusion (4314) is relatively weak, it is difficult to effectively limit the cleaning fluid box (440). When the protrusion (4314) is relatively thick and it is necessary to make the groove (4315) large, the cleaning fluid box may sacrifice a certain capacity. Accordingly, referring to FIG. 42, the size (d7) of the protrusion (4314) along the length of the bottom brush (400) is within the range of 7 mm to 10 mm.

[0254] In some embodiments, the cleaning fluid box (440) may be connected to the installation housing (431) by a connecting structure such as a locking structure or a clamping structure. However, considering that the connecting structure requires a relatively large amount of space and must be arranged in a conspicuous location, the cleaning fluid box (440) may be fixed to the installation housing (431) via a magnetic suction structure. In some embodiments, as shown in FIGS. 38, 39, and 45, a first iron body (441) may be fixed to the bottom of the cleaning fluid box (440), and a first magnet (442) capable of generating suction force with the first iron body is fixed to the roller brush installation cavity (450). Accordingly, the space occupancy of the connecting structure is reduced, and since the connecting structure is hidden, the structure of the working part (410) becomes compact and aesthetic. In some embodiments, the above magnetic attraction structure may be realized by swapping the positions of the first iron body (441) and the first magnetic body (442) and arranging two magnetic attraction magnets.

[0255] In some embodiments, as illustrated in FIGS. 42 and 43, a first fluid outlet (443) and a positioning block (444) may also be provided at the bottom of the cleaning fluid box (440). The first fluid outlet (443) forms a valve assembly in which a first fluid plug (4319) is disposed in the installation housing (431). When both are closed together, the cleaning fluid may flow out of the cleaning fluid box (440). The positioning block (444) may be inserted into the plug (4318) of the installation housing (431) to perform a positioning function. Furthermore, the valve assembly may have other configurations. As illustrated in FIGS. 40 and 41, in some embodiments, a valve assembly (4405) may be provided at the outlet (4401) of the cleaning fluid box (440), and at least a portion of the valve assembly (4405) may extend into the interior of the cleaning fluid box (440). In some embodiments, the valve assembly (4405) may include an assembly outlet (44051), a load-release plug component (44052), and a plug member spring (44053). In some embodiments, the assembly outlet (44051) may be a structural body that penetrates the interior. That is, the assembly outlet (44051) has an internal channel. The component outlet (44051) is installed at the outlet (4401) of the cleaning fluid box (440) via a threaded cap (44054). The load-release plug component (44052) is fitted to the component outlet (44051) via a washer (e.g., an O-ring), and the load-release plug component (44052) can control the open and closed state of the internal channel of the component outlet (44501). That is, the open and closed state of the internal channel of the component outlet (44051) can be changed by changing the position of the load-release plug (44052).As merely an exemplary example, in some embodiments, the load release plug component (44052) is a cylindrical structure, and the load release plug component (44052) may include a first cylindrical structure and a second cylindrical structure connected sequentially from the top to the bottom. The radius of the first cylindrical structure is larger than the radius of the second cylindrical structure, and the radius of the first cylindrical structure is approximately equal to the inner diameter of the component outlet (44051). The second cylindrical structure is approximately equal to the inner diameter of the second cylindrical structure, and the radius of the second cylindrical body is smaller than the inner diameter of the component outlet (44051). The plug member spring (44053) deflects the valve assembly (4405) to a closed position within the spring housing (44056). Specifically, by the action of the plug member spring (44053), the first cylindrical structural body of the load-release plug component (44052) is fitted and connected inside the component outlet (44051), at which point the valve assembly (4405) is closed and the cleaning fluid of the cleaning fluid box (112) cannot flow out of the cleaning fluid box (440) and into the outside world. When the valve assembly (1130) is connected to the cleaning fluid supply assembly, the load-release plug component (44052) deforms the plug member spring (1138) under the pressure action of the pipeline interface, and the first cylindrical structural body of the load-release plug component (44052) moves relative to the internal channel of the component outlet (44051), at which time the second cylindrical structural body is positioned in the internal channel of the component outlet (44051). The second cylindrical structure body has a gap between the second cylindrical structure and the side wall corresponding to the internal channel of the assembly outlet (1132), and the valve assembly (4405) is open to discharge fluid into the fluid transfer channels (e.g., the first pipe, the second pipe, and the third pipe).In some embodiments, the load release plug component (44052) may be a retractable rod structure, that is, the radius of the load release plug component (44052) gradually decreases from the top to the bottom. The principle regarding the load release plug component (44052) may be a retractable rod structure and may be aligned with the assembly outlet (44051), and may refer to the description above. In some embodiments, the valve assembly (4405) may also include a filter mesh plug member (not shown in the drawing), and the filter mesh plug member is configured to prevent particulates from entering the cleaning fluid supply assembly. In some embodiments, the filter mesh plug member may be provided between the cleaning fluid box outlet (4401) and the valve assembly (4405). In some embodiments, the filter mesh plug member may also be provided on one side of the outlet (4401) of the cleaning fluid box (440), away from the valve assembly (4405).

[0256] In some embodiments, the water outlet area of ​​the valve assembly may be larger than 3 mm² so that the cleaning fluid from the nozzle (460) to the floor to be cleaned can wet the floor. In some embodiments, the water outlet area of ​​the valve assembly may be larger than 4 mm². In some embodiments, the water outlet area of ​​the valve assembly may be larger than 5 mm². In some embodiments, the water outlet area of ​​the valve assembly may be larger than 6 mm². In some embodiments, the valve assembly may be released from the load release plug component (44052) or the valve assembly outlet (44051) by adjusting the inner diameter of the assembly outlet (44051) or by adjusting the load release plug component (44052) to ensure that the amount of water coming out of the valve assembly is maintained. For example, the water outlet area of ​​the valve assembly is increased by reducing the radius of the second cylindrical structure of the load release plug component (44052). In some embodiments, as shown in FIG. 41, the distance between the end of the load-release plug component (44052) moving away from the cleaning fluid box (440) and the cleaning fluid box (440) along the height direction (the H direction shown in FIG. 35) of the cleaning fluid box (440) is smaller than the distance (d11) from one end of the screw cap (44054) moving away from the cleaning fluid box (440) and the cleaning fluid box (440). Accordingly, on the one hand, the load-release plug component (44052) can be prevented from colliding with an external object and leaking, and on the other hand, it is also convenient for a staff to verify the valve assembly (4405), and the staff can press the load-release plug component (44052) to observe whether the valve assembly (4405) is normal. In some embodiments, the distance (d11) may be 0.2 mm to 0.8 mm. In some embodiments, the pitch (d11) may be 0.3 mm to 0.6 mm. In some embodiments, the pitch (d11) may be 0.4 mm to 0.5 mm.

[0257] It should be noted that the valve assembly is not limited to the valve assembly composed of the aforementioned first liquid outlet (443) and positioning block (444) and the valve assembly (4405) shown in FIGS. 40 and 41, and the valve assembly may be any type of assembly that realizes liquid conduction / blocking by pulling and inserting movements, and is not further limited thereto. Additionally, the shape of the load release plug component (44052) may be a different shape, such as a rectangular body structure, a trapezoidal body structure, a circular table structure, etc., and accordingly, the shape of the internal channel of the load release plug component (44052) is matched to the shape of the load release plug component (44052).

[0258] In some embodiments, the aforementioned valve assembly may be any one of the assemblies that realize liquid conduction / blocking by pulling and inserting movements.

[0259] It should be noted that the maximum height, maximum width, and maximum length of the cleaning fluid box (440) refer to the size (e.g., height, width, length) of the cleaning fluid box (440) and do not include protrusions such as the first fluid outlet (443) and the positioning block (444).

[0260] In some embodiments, as illustrated in FIG. 38, the cleaning fluid supply assembly further includes a nozzle (460) and a pump (461). The pump (461) may be configured to pump cleaning fluid from the cleaning fluid box (440) to the nozzle (460), and the nozzle (460) may serve as the output end of the cleaning fluid supply assembly for cleaning and / or controlling the floor by spraying cleaning fluid onto the floor to be cleaned. In some embodiments, the pump (461) may be placed in a roller brush mounting cavity (450) configured along the length of the floor brush (400) on one side of the floor brush channel (451), and the nozzle (460) may be placed in the upper baffle cover (432).

[0261] Referring to FIG. 42, to prevent the capacity of the cleaning fluid box (440) from being excessively reduced, the top of the pump (461) may be higher than the lowest surface inside the receiving box (4313). That is, a first projection (43141) capable of at least partially accommodating the pump (461) is provided on the bottom surface of the receiving box (4313). Corresponding to FIG. 38 and FIG. 40, a concave portion (not shown in the drawings) may be provided on the bottom of the cleaning fluid box (440) to prevent the first projection (43141) of a first groove (not shown in the drawings) from forming. In some embodiments, the top of the bottom brush channel (451) may be higher than the lowest surface inside the receiving box (4313). That is, a second projection (4316) capable of at least partially accommodating the bottom brush channel (451) may be provided on the bottom surface of the receiving box (4313). In response to this, a second concave portion (not shown in the drawing) may be provided at the bottom of the cleaning fluid box (440) to avoid the second protruding portion (4316). Considering the pumping volume of the cleaning fluid and the amount of waste transported, the pump (461) and the floor brush channel (451) must each reach a certain height, and if the bottom surface of the receiving box (4313) is basically arranged as a flat plane, the height of the plane may vary depending on the height of the top of the pump (461) and the floor brush channel (451), so it must be understood that some space that could undoubtedly be used to extend the capacity of the cleaning fluid box may be sacrificed. Accordingly, the height of the cleaning fluid box (440) and the floor brush body (430) can be defined so that the capacity of the cleaning fluid box (440) can be sufficiently secured, the structure of the working part (410) can be made more compact and practical, and the user can conveniently use the floor brush in a space with limited height, such as under a bed.It should be noted that the lowest surface within the receiving box (4313) refers to the substantially flat bottom of the receiving box (4313) connected to the first protrusion (43141) and the second protrusion (4316).

[0262] In some embodiments, as illustrated in FIG. 38, the mounting housing (431) may be provided with a second liquid outlet (4317), and the upper baffle cover (432) may be provided with a second liquid plug (4321) capable of forming a valve assembly with the second liquid outlet (4317). Specifically, the pump (461) has a pump inlet and a pump outlet, the pump inlet may be fluidly connected to the first liquid plug (4319) through a first conduit, the pump outlet may be fluidly connected to the second liquid plug (4317) through a second conduit, and the second liquid plug (4321) may be fluidly connected to the nozzle (460) through a third conduit (4322). The first conduit and the second conduit are configured in the roller brush installation cavity (450), the third conduit (4322) is configured in the upper baffle cover (432), and the nozzle (460) is located on the upper baffle cover (432) above the roller brush (433). When the surface to be cleaned needs to be wet, the cleaning fluid in the cleaning fluid box (440) is operated under the influence of the action of the pump (461), and the cleaning fluid flows sequentially through a valve assembly comprising a first fluid outlet (443) and a first fluid plug (4319) (see FIG. 42), a first conduit, a pump (461), a second conduit, and a second fluid outlet (4314), and a second valve assembly comprising a second fluid plug (4321), a third conduit (4322), and a nozzle (460), and flows out into the external environment to wet the surface to be cleaned in front of the roller brush (433). In some embodiments, the number of nozzles (460) may be one or more. When the number of nozzles (460) is multiple, one or more nozzles (460) may be spaced apart along the longitudinal direction of the upper baffle cover (432) [in the same direction (n) as the longitudinal direction of the roller brush (433) shown in FIG. 38] to increase the wetting area of ​​the nozzles (460). By configuring two valve assemblies and arranging three conduits, effective injection and separation between multiple parts of the cleaning fluid supply assembly can be realized.

[0263] When performing a cleaning operation, the roller brush (433) may be rotated by the drive of the motor (4331). In some embodiments, the motor (4331) may be provided in the roller brush mounting cavity (450) and configured along the length of the floor brush on the other side of the floor brush channel (451). In some embodiments, the motor (4331) may be provided inside the roller brush (433), which can further optimize the size of the working part (410) and improve the miniaturization of the working part (410).

[0264] In an embodiment in which a motor (4331) is provided inside a roller brush (433), a first brush support is fixed to one side of a bottom housing (4311) for fixing the motor (4331). In some embodiments, a support arm (4333) may be configured as a first brush support that extends forward along the width direction of the bottom brush. One end of the motor (4331) is fixed to the support arm (4333) by a coupling sleeve (4334), and the other end of the motor (4331) is connected to a gearbox body (4332) so as to act directly on the roller brush (433) to drive the roller brush to rotate.

[0265] Referring to FIGS. 45 and 46, in some embodiments, the roller brush (433) may include a brush barrel (4335) and brush bristles (4336) fixed around the circumference of the brush barrel (4335). The brush barrel (4335) is fixed to a partition plate (4337) perpendicular to the longitudinal direction inside, and a plurality of connecting grooves (43371) are uniformly provided in the partition plate (4337), and a plurality of connecting posts (43372) that can be fitted into the corresponding connecting grooves (43371) are provided in a corresponding manner on the output shaft of the gearbox body (4332). A plurality of connecting posts (43372) that can be inserted into the connecting grooves (43371) are provided on the output shaft of the gearbox body (4332). When the motor (4331) is activated, the connecting post (43372) can apply force to the connecting groove (43371) to realize rotational driving of the roller brush.

[0266] In some embodiments, the connecting posts (43372) extend outward along the radial direction of the output shaft of the gearbox body, and the greater the number, the better the transmission stability between the roller brush (433) and the gearbox body (4332). In a preferred embodiment of the present invention, the number of connecting posts (43372) and connecting grooves (43371) may both be three. It should be noted that the number of connecting posts (43372) and connecting grooves (43371) is not limited to three, but may be one, two, or three or more, and the specific number may be adaptively adjusted according to actual circumstances.

[0267] When cleaning is complete, there are cases where the roller brush (433) must be disassembled and cleaned separately. Since the motor (4331) and the gearbox body (4332) are provided inside the brush cylinder (4335), the roller brush (433) can be pulled only along its length against the floor housing (4311). However, when re-mounting the roller brush (433), the connecting post (43372) and the connecting groove (43371) are not easily aligned, resulting in a poor user experience. To solve this problem, in some embodiments, the connecting post (43372) may be substantially cylindrical, while the outer edge of the connecting groove (43371) is simultaneously formed into a rounded corner or a chamfered corner (43373). Based on the above structure, the substantially cylindrical connecting post (43372) can be smoothly embedded in the connecting groove (43371) along the rounded or chamfered edge during the process of inserting the roller brush (433).

[0268] As illustrated in FIGS. 43 and 44, in some embodiments, the bottom housing (4311) is configured such that a second brush support portion is detachably configured at the end limit of the brush (433) on the other side of the bottom housing (4311) away from the support arm (4333) for rotational support. In some embodiments, the support assembly (470) may be used as a second roller brush support portion.

[0269] As illustrated in FIGS. 35, 48, and 49, in some embodiments, the support assembly (470) may include a cover plate member (471), and the cover plate member (471) may be fixed to the installation housing (431) by a magnetic attraction structure. Specifically, the cover plate member (471) is provided with a second iron body (4711) on the side facing the bottom housing (4311), the bottom housing (4311) is provided with a side plate (43111), and the side plate (43111) is provided with a second magnet (4311) (not shown in the drawings). By concealing the connection structure of the support assembly (470), the maximum size can be easily controlled along the length of the working part (410). In other embodiments, the magnetic fixation of the support assembly (470) may be realized by arranging the second iron body (4711) and the second magnet, or by arranging two magnets.

[0270] By fixing the support assembly (470) according to the magnetic structure, the size of the cover plate member (471) and the bottom housing (4311) along the longitudinal direction is easily adjusted, and the length ratio of the roller brush (400) of the working part (410) is optimized. In some embodiments, the ratio of the maximum longitudinal size of the roller brush (400) to the maximum longitudinal size (d1) of the working part (410) may be 0.9 or greater. Thus, when performing a single push-pull cleaning, the roller brush rubs the surface to be cleaned as much as possible, so there is no significant difference between the rubbing length (maximum longitudinal size of the roller brush) and the maximum longitudinal size of the working part, thereby improving the cleaning effect and cleaning efficiency.

[0271] In order to strengthen the connection between the cover plate member (471) and the side plate (43111) and to prevent the support assembly (470) from rotating relative to the side plate (43111), a part of the cover plate member (471) may be embedded in the side plate (43111). Additionally, a limiting groove (4712) is provided on the side of the cover plate member (471) facing the bottom housing (4311) so that the cover main body plate member (471) can be installed in place, and a limiting block (4713) that can be inserted into the limiting groove (4712) is provided on the side plate (43111).

[0272] In some embodiments, as shown in FIG. 48, a support sleeve (472) is fixed to the side of a cover plate member (471) facing a bottom housing (4311), and a first bearing member (473) is installed inside the support sleeve (472) via a clamping spring (4731). A connecting rod (474) is fixedly inserted into the inner ring of the first bearing member (473), and the other end of the connecting rod (474) is forcibly inserted into a rotating sleeve (475).

[0273] In some embodiments, as illustrated in FIGS. 45 and 47, a second bearing member (476) is additionally installed in the connecting sleeve (4334), and in use, the brush barrel (4335) is placed in the rotating sleeve (475). The rotating sleeve (475) and the second bearing member (476) support the right and left sides of the roller brush (433), respectively. Under the action of the two bearing members (the first bearing member (473) and the second bearing member (476)), the rotational resistance of the roller brush (433) is reduced.

[0274] As illustrated in the combination of FIGS. 48 and 49, this is intended to prevent friction caused by a mismatch in rotational speed between the roller brush (433) and the rotating sleeve (475). In some embodiments, the rotating sleeve (475) may be provided with a flange (4751), and a plurality of notches (4750) may be provided in the flange (4751), and correspondingly, the brush barrel (4335) is composed of a plurality of plug blocks (43351). In use, the plug blocks (43351) are plugged into the notches (4750) to ensure perfect facing synchronization between the roller brush (433) and the rotating sleeve (475) during circumferential rotation. In some embodiments, the longitudinal size of the flange (4751) may be greater than the thickness of the brush cylinder (4335), which is equivalent to blocking one end of the brush cylinder (4335) by the rotating sleeve (475) to prevent debris from entering the brush cylinder (4335). The rotating sleeve (475) is provided with an annular groove along the circumferential direction, and a sealing ring (477) is formed in the annular groove to contact the inner wall of the brush cylinder (4335) to further enhance the blocking effect against debris.

[0275] In some embodiments, as illustrated in FIG. 48, a recess (4714) is provided on the side of the cover plate member (471) that returns to the bottom housing (4311), and a pull block (4715) is installed in the recess (4714) so ​​that a user can grasp the pull block (4715) with their hand to disassemble and assemble the support assembly (470). In some embodiments, the pull block (4715) is placed entirely within the recess (4714) so ​​that the pull block (4715) does not protrude outside the dorsal plane of the cover plate member (471), thereby preventing it from easily colliding with an obstacle without affecting the maximum size along the longitudinal direction of the working part (410).

[0276] In some embodiments, the pull block (4715) and the support sleeve (472) may be connected together by a bolt, screw, etc., which facilitates the design for detachment and facilitates subsequent cleaning and maintenance of the components. In some embodiments, the cover plate member (471) may be provided with a limiting sleeve (4716), and the support sleeve (472) is forced into the limiting sleeve (4716). Accordingly, the installation stability of the support sleeve (472) is improved, preventing the support sleeve (472) from shaking against the cover body plate member (471), thereby ensuring the rotational dynamic balance performance of the roller brush (433).

[0277] Since the rotating sleeve (475) can diffract with respect to the cover plate member (471), a gap must be formed between the rotating sleeve (475) and the cover plate member (471). Filamentous materials such as hair or silk may enter the rotating sleeve (475) through the gap above during the cleaning process. This is to prevent filamentous materials from getting entangled in the rotating members (first bearing member (473), connecting rod (474), etc.). In some embodiments, the support sleeve (472) is provided with a flared portion (4721) on the side facing the rotating sleeve (475), and the flared portion (4721) surrounds the rotating members (e.g., first bearing member (473), connecting rod (474), etc.) to prevent the channel between the rotating members and the external environment from twisting and coming into contact with the rotating members. At the same time, the flared portion (4721) does not interfere with the rotation of these rotating members. In a specific embodiment, along the height direction (m) of the roller brush (433) (shown in FIG. 38), the minimum distance between the flare portion (4721) and the rotating sleeve (475) is 1.5 mm or less. Along the length direction (n) of the roller brush (433) (shown in FIG. 38), the minimum distance between the flare portion (4721) and the rotating sleeve (475) is 1.5 mm or less. In this case, due to these small distances, it becomes more impossible for filamentous material to reach the rotating member. In this case, since the support sleeve (472) and the rotating sleeve (475) are arranged approximately coaxially, the two minimum distances described above are, respectively, the minimum distance between the outer edge of the flare portion (4721) and one inner wall of the rotating sleeve (475) and the minimum distance between the right end of the flare portion (4721) and the other inner wall of the rotating sleeve (475).
