Specifically, under the suction force of the handheld vacuum cleaner 3 , the fluid enters the dust cylinder assembly 31 from the air inlet 310 of the handheld vacuum cleaner 3 to separate dust and air, and the separated clean air is discharged from the air outlet of the handheld vacuum cleaner 3 .

It is worth noting that the fluid involved in this specification can be a clean airflow or an airflow entrained with dirt; the dirt is dust, solid dirt (such as cigarette butts, paper, rice grains, etc.), At least one of dirty liquids (such as orange juice, dirty water, egg liquid, etc.).

It can be understood that, in the stick vacuum cleaner mode, the dirt storage tank 4 constitutes the first separation structure; when the airflow entrained with dirt flows through the dirt storage tank 4, the dirty liquid and solid dirt contained therein And dust can be intercepted and stored in dirt storage tank 4. Since dust and gas-liquid (gaseous liquid droplets) have the characteristics of small size and light weight, it is inevitable that they will be guided to the dust cylinder assembly 31 together with the air flow; If there is dirt trapped in the airflow of the assembly 31, the dust cylinder assembly 31 can separate the dust and gas, intercept and store the dirt in the dust cylinder assembly 31, and guide the airflow to the air outlet of the hand-held vacuum cleaner for discharge.

Based on the above settings, the cleaning device 100 provided in the embodiment of this specification can have a basic dust collection function, that is, clean and dry solid dirt and dust, and can also clean wet, dirty liquid or mixed with dry dirt. That is, it has the function of both wet and dry. Moreover, after the fluid absorbed by the floor brush 2 passes through the dust storage box 4 and the dust cylinder assembly 31 of the handheld vacuum cleaner 3 for two-stage dust and gas separation, relatively clean air can be obtained, which can reduce air pollution during the cleaning process. Moreover, the hand-held vacuum cleaner 3 can also be removed for use separately, realizing the function of hand-held vacuuming. The cleaning device 100 combines multiple functions in a unified manner and has diversified usage modes. It is not only compact and practical, but also saves the space required for placing multiple cleaning devices. For example, the handheld vacuum cleaner 3 can be installed on the body 1 after being used alone , no need to be placed separately.

In some embodiments, the cleaning device 100 may further include a cleaning liquid supply assembly. The cleaning liquid supply assembly may include a cleaning liquid tank 50 for storing cleaning liquid. The cleaning liquid tank 50 is detachably installed on the floor brush 2 .

In some embodiments, the cleaning device 100 also has the function of cleaning the floor. Cleaning the ground can be mainly realized by the cleaning liquid supply assembly and the floor brush 2 .

In some embodiments, the cleaning liquid supply assembly may further include a spray head and a pump, and the spray head and the pump may form a water spray system. In some embodiments, the pump can be used to guide the cleaning liquid from the cleaning liquid tank 50 to the spray head, and the spray head can be used as the output end of the cleaning liquid supply assembly to spray the cleaning liquid to the floor brush 2 or the ground, thereby playing a role in cleaning the ground. cleaning and/or care. In some embodiments, the cleaning solution may be clear water, or cleaning agent, care agent and the like.

By arranging the dirt storage tank 4 on the fuselage 1 and the cleaning liquid tank 50 on the ground brush 2, the positions of the two tanks are reasonably allocated, so that the fuselage 1 will not be too bulky and is convenient for users to hold and operate. In some embodiments, by setting the cleaning liquid tank 50 on the ground brush 2, the distance between the cleaning liquid tank 50 and the ground brush 2 is relatively short, and there is no need to set a longer distance between the cleaning liquid tank 50 and the ground brush 2. The cleaning liquid pipe, and make the nozzle spray cleaning liquid correspondingly faster. In addition, the cleaning liquid tank 50 is arranged on the floor brush 2 , which increases the weight of the floor brush 2 , thereby increasing the pressure of the floor brush 2 on the ground, thereby improving the cleaning effect of the floor brush 2 . In some embodiments, the dirt storage tank 4 is arranged on the fuselage 1 instead of the ground brush 2, which can avoid the excessive size of the ground brush 2 due to more attachments on the ground brush 2, thereby affecting its cleaning range . Therefore, based on the above optimized structure, it can solve the problem that the fuselage is too bulky. It not only facilitates the user's hand-held operation, but also has many improvements such as easy cleaning in a height-limited space.

In some embodiments, during the use of the cleaning device 100, operations such as filling and cleaning the cleaning solution tank 50 may be required, and the dirt storage tank 4 may also be cleaned. Therefore, the cleaning solution tank 50 is relatively And the dirt storage tank 4 can be disassembled with respect to the fuselage 1, so that operations such as filling and cleaning the cleaning liquid tank 50 are performed separately, or the dirt storage tank 4 is cleaned separately.

The areas of the first cross-section corresponding to each position in the length direction of the vacuum cleaner 3 are the same or substantially the same, and the areas of the second cross-section corresponding to each position of the main body of the handheld vacuum cleaner 3 along the length direction (or first direction Y) of the fuselage are the same or substantially the same. same. Wherein, the first cross-section is a cross-section of the main body of the combined body perpendicular to the length direction of the fuselage, and the second cross-section is a cross-section of the main body of the handheld vacuum cleaner perpendicular to the length of the fuselage. In some embodiments, the first section of the main body of the combined body has a first preset cross-sectional area, and the areas of the first cross-sections corresponding to the various positions of the main body of the combined body along the length direction of the fuselage are substantially the same. The difference between the area of the first cross-section and the first preset cross-sectional area is 1%, 2%, 3%, etc. of the first preset cross-sectional area. Similarly, the second cross-section of the main body of the handheld vacuum cleaner 3 has a second preset cross-sectional area, and the areas of the second cross-section corresponding to each position of the main body of the handheld vacuum cleaner 3 along the length direction of the fuselage are basically the same.

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 also not include the handheld vacuum cleaner 3 . For example, the part of the handheld vacuum cleaner 3 in FIG. 4 may be an upwardly extending part of the fuselage 1, and the area of the section of the extension part perpendicular to the length direction of the fuselage 1 is smaller than the area of the first section. In some embodiments, as shown in FIG. 4 , a motor 34 can be provided in the fuselage 1 and above the dirt storage tank 4, and the motor 34 can provide suction for the cleaning device 100 to absorb dirt on the ground (or surface to be cleaned). of fluid.

Fig. 5 is a right side view of a cleaning device according to some embodiments of the present specification. Fig. 6 is a disassembled structure diagram of the cleaning device shown in Fig. 5 . FIG. 7 is a partial structural schematic diagram of the cleaning device shown in FIG. 5 .

In some embodiments, the cleaning device 100 in the embodiments of this specification may also have the structural form shown in Figures 5-7, the difference between the structure shown in Figures 5-7 and the structure shown in Figures 1-3 or Figure 4 is mainly The location of the hand-held vacuum cleaner 3 is different, that is, the hand-held vacuum cleaner 3 shown in FIGS. The same side of the dirt storage tank 4 (for example, the front side of the fuselage 1).

Further, as shown in FIG. 5 and FIG. 6 , the body 1 of the cleaning device 100 may include a rod-shaped shaft 11 as a whole; The ground brush connecting end 111 on the connecting portion 420 of the ground brush 400 shown, the upper part of the shaft 11 is provided with a handle end 112 which is convenient for the user to hold.

The front side of the fuselage 1 is separately and detachably equipped with a hand-held vacuum cleaner 3 and a dirt storage box 4 (for example, the dirt storage box 4 or 300), and the hand-held vacuum cleaner 3 is arranged on the top of the dirt storage box 4; The ground brush 2 and the first channel 6 of the dirt storage tank 4. The working principle of the cleaning device 100 shown in FIGS. 5-7 is similar to the working principle shown in FIGS. 1-3 , for related descriptions, please refer to FIGS. 1-3 and related descriptions, and details will not be repeated here.

In some embodiments, as shown in FIG. 7 , the fuselage 1 may include a fixing seat 115 , and the fixing seat 115 may protrude outward relative to the shaft 11 of the fuselage 1 . Disconnect the connection.

In some embodiments, the fixing seat 115 is provided with a through hole 1151 , and the end of the dust cylinder assembly 31 having the air inlet 310 can be matedly connected with the through hole 1151 . The mating connection here means that the shape of the end with the air inlet 310 in the dust cylinder assembly 31 is adapted to the shape of the through hole 1151, so that the dust cylinder assembly 31 can form a sealed passage with the through hole 1151, so that the air from the dust storage can be protected. The fluid in Tank 4 is processed. In addition, the user can directly take out the handheld vacuum cleaner 3 plugged on the fixing seat 115 so as to use the handheld vacuum cleaner 3 alone. By setting in this way, the fluid tightness and locking stability between the handheld vacuum cleaner 3 and the dirt storage tank 4 can be taken into account. As an illustration, as shown in Figure 6, the hand-held vacuum cleaner 3 and the dirt storage tank 4 can be connected to the top and bottom of the through hole 1151 in a sealed and fluid communication manner; the fluid after the first stage separation enters through the through hole 1151 into the air inlet 310 of the hand-held vacuum cleaner 3.

In some embodiments, the dirt storage box 4 can be located at the end of the fixing seat 115 away from the handheld vacuum cleaner 3 , and the dirt storage box 4 is detachably connected to the main body 1 through the fixing seat 115 . For example, the end of the dirt storage box 4 away from the ground brush 2 is mated with the end of the fixing seat 115 away from the hand-held vacuum cleaner 3 , so as to realize the detachable connection between the dirt storage box 4 and the fixing seat 115 .

In some embodiments, in order to improve the connection reliability between the handheld vacuum cleaner 3 and the dirt storage tank 4 and the main body 1, the main body 1 may include a first locking mechanism 113, and the first locking mechanism 113 is used to lock the handheld vacuum cleaner 3 is locked to the body 1. In some embodiments, the body 1 may include a second locking mechanism 114 for locking the dirt storage tank 4 to the body 1 . By providing the first locking mechanism 113 and the second locking mechanism 114 , both the handheld vacuum cleaner 3 and the dirt storage tank 4 can be independently detachable relative to the main body 1 . In some embodiments, the first locking structure 113 and the second locking structure 114 may be any one of a locking structure, a buckle structure, a magnetic attraction structure, an adhesive structure, and the like.

As shown in Figure 3, in order to improve the installation stability of the dirt storage tank 4, the fuselage 1 can also include a dirt storage tank support seat 5, and the dirt storage tank support base 5 can support the storage tank from the bottom or side of the dirt storage tank 4. The dirt tank 4 is supported, so that the dirt storage tank 4 can be more stably connected to the fuselage 1 . In some embodiments, the dirt storage tank support base 5 can be arranged at the rear of the fuselage 1 . Wherein, the rear of the body 1 may refer to the side where the body 1 faces the user when the user operates the cleaning device 100 (for example, the right side of the body 1 shown in FIG. 3 ).

In some embodiments, the dirt storage tank support seat 5 can be configured as a groove, which is arranged behind the fuselage 1, and the dirt storage tank 4 is at least mostly accommodated in the groove. In some embodiments, more than half of the volume of the dirt storage tank 4 is installed in the groove, which can make the structure of the fuselage after the dirt storage tank 4 is installed relatively smooth and smooth, and is not easy to be bumped or bumped into other objects.

In some embodiments, when the second locking structure 114 unlocks the dirt storage tank 4, one end of the dirt storage tank support seat 4 can automatically move away from the fuselage 1 to form a certain angle between the dirt storage tank 4 and the fuselage 1, thereby It is convenient for the user to take out the dirt storage box 4 . The certain angle here may not be greater than 45°. For example, a certain angle may be other angles such as 15°, 20°, 30°, 45° and the like. It should be noted that the angle may also be greater than 45°, such as 50°, 60° and other angles. The specific value of the angle can be selected according to the actual situation, so that the user can take out the dirt storage tank 7 and prevent the liquid in the dirt storage tank 7 from overflowing.

In some embodiments, the dirt storage tank support base 5 is pivotally connected to the fuselage 1, and its end away from the pivot joint is configured with a plate or block-shaped plug, between the dirt storage tank support base 4 and the fuselage 1 An elastic piece is provided, and the elastic piece can bounce the support seat 5 of the dirt storage tank relative to the fuselage 1, so that the plug piece is automatically moved away from the fuselage 1. For example, in some embodiments, as shown in FIG. 6 and FIG. 7 , one end of the dirt storage tank 4 is connected with the fixed seat 115, and the other end of the dirt storage tank 4 is connected with the dirt storage tank support base 5. At this time, the dirt storage tank Part of the side wall of the dirt tank 4 is attached to the fuselage 1, and the elastic member is in a compressed state under the action of the dirt storage tank 4 and the plug. When the user separates the dirt storage tank 4 from the fixing seat 115 , under the elastic force of the elastic member, the plug is kept away from the fuselage 1 , and at the same time, the plug will also drive the dirt storage tank 4 away from the fuselage 1 . In some embodiments, the spring member may include one or more of springs, leaf springs, bellows, and the like. The dirt storage tank 4 is provided with a socket 41 that can be inserted into the plug. When the plug rotates, the dirt storage tank 4 can be linked with the plug through the socket 41 . For example, when the plug part is away from the fuselage 1 under the action of the elastic member, the dirt storage tank 4 is away from the fuselage 1 together with the plug piece, and the process that the dirt storage tank 4 is far away from the fuselage 1 can be regarded as the automatic swing of the dirt storage tank 4 out. In some embodiments, the position of the plug part and the socket part can also be exchanged to achieve the effect that the dirt storage tank 4 can be automatically swung out.

When there is liquid in the dirt storage tank 4, if the angle of automatic swing is too large, it is easy to cause the liquid to splash or even overflow. Therefore, the angle of the dirt storage tank 4 relative to the fuselage 1 can be no more than 45°, specifically through A limiting plate is installed on the fuselage 1 to limit the maximum rotation range of the second locking structure 114 . In addition, in order to avoid the process of automatically swinging out too quickly, causing the liquid in the dirt storage tank 4 to slosh violently, in some embodiments, a rotation damper is installed at the pivot joint of the dirt storage tank support base 5 .

By setting a fixed seat 115 protruding relative to it on the body 1, the center of gravity and most of the weight of the handheld vacuum cleaner 3 are supported on the fixed seat 115 instead of the body 1. In addition, a first lock is set on the body 1. The tightening mechanism 113, through the cooperation of the fixing seat 115 and the first locking structure 113, can achieve the purpose of stably fixing the handheld vacuum cleaner 3. In addition, the contact area between the fuselage 1 and the dirt storage tank 4 can also be reduced by arranging the dirt storage tank support base 5 , the fixing base 115 and the second locking structure 114 on the fuselage 1 .

The vacuum cleaner provided in the embodiment of this specification realizes that the hand-held vacuum cleaner 3 or the sewage The fixing of the box 4 can minimize the requirement on the supporting area of the fuselage 1, so that the shaft 11 can be configured as a slender rod shape (referred to as a slender rod type), thereby reducing the overall weight of the fuselage 1 . For example, the overall weight of the fuselage can be reduced by more than 70%, and the appearance of the whole machine is more concise and refreshing.

Further, the cross-sectional area of the shaft 11 of the slender rod type has no significant change along its length direction. The cross-sectional area in the length direction of the shaft 11) will inevitably have some changes, and no significant change here means that most of the cross-sectional area of the shaft 11 along the length direction (Y direction shown in FIG. 3 ) has no significant change. The cross-sectional area of the shaft 11 will have a minimum value and a maximum value, and even the maximum cross-sectional area should be smaller than the average cross-sectional area of the fixing seat 115, the average cross-sectional area of the hand-held vacuum cleaner 3, and the average cross-sectional area of the dirt storage tank 4 any of the . Wherein, the average cross-sectional area of the fixing seat 115 refers to an average value of the cross-sectional areas of different positions of the fixing seat 115 in the length direction of the shaft 11 . The average cross-sectional area of the handheld vacuum cleaner 3 refers to the average value of cross-sectional areas at different positions of the handheld vacuum cleaner 3 in the length direction of the shaft 11 . Preferably, the maximum cross-sectional area of the shaft 11 may be less than half of any cross-sectional area of the three, so as to ensure the portability of the shaft 11 . In some embodiments, the ratio range of the dimension U1 of the shaft 11 along the front-rear direction (the X direction shown in FIG. 7 or called the width direction) to the dimension V1 of the fuselage 1 along the length direction (the Y direction shown in FIG. 7 ) It can be 0.02-0.06. Wherein, the dimension U1 of the shaft 11 along the width direction may range from 43 mm to 49 mm, and the dimension V1 of the shaft 11 along the length direction may range from 1000 mm to 1200 mm. Through the above settings, the overall weight of the body can be reduced, which is convenient for users to hold and use, and the overall size and weight of the cleaning device 100 can be optimized.

In some embodiments, the fixing seat 115 can be approximately circular, and the ratio range of the maximum dimension of the fixing seat 115 along the width direction (for example, U2 shown in FIG. 7 ) to the dimension U1 of the shaft 11 along the width direction can be 1.8-3, so that under the condition of ensuring the performance, the overall width of the fixing seat 115 and the shaft 11 can be designed to be as small as possible, so that it is convenient to control the shaft 11 to extend the floor brush 2 deeply into the bottom of the bed. Projecting along the length direction of the fuselage 1 , the ratio of the projected area of the fixing seat 115 to the projected area of the shaft 11 is in the range of 6.5-9. The projected area here refers to the area surrounded by the outer edges of the cross-sectional area. Specifically, the projected area of the fixing seat 115 is 55cm ² -80cm ² .

In some embodiments, as shown in FIGS. 1 to 4 , the dirt storage tank 4 can be arranged on the rear side of the fuselage 1 (that is, the side facing the user when the user operates the cleaning device 100 ), for example, set on the dirt storage tank support. on the seat 5 (for example, a groove). In some embodiments, as shown in FIGS. 5-7 , the dirt storage tank 4 may be arranged on the front side of the fuselage 1 . It should be noted that when this specification refers to front and rear orientations such as "front side" and "rear side", unless otherwise specified, "front side" may refer to the direction facing away from the user when operating the cleaning device 100. side (eg, the left side in Figure 4), while the "rear side" is the side that faces the user (eg, the right side in Figure 4). For example, as shown in FIG. 4, the direction of the arrow A is "rear", and the direction opposite to the arrow A is "front".

Fig. 10 is a schematic structural diagram of a partition according to some embodiments of the present specification. As shown in FIG. 10 , a first hole group 231 is provided on the partition plate 203 . The anti-reverse flow structure 230 includes an anti-reverse valve 232 installed on the partition plate 203 corresponding to the first hole group 231 . The anti-reverse valve 232 is located in the lower space 205 and communicates with the upper space 204 through the first hole group 231 . In addition, the first portion 206 of the edge of the partition 203 may be in sealing contact with the side walls of the box 201 . In some embodiments, a sealing ring may be provided between the edge of the partition plate 203 and the side wall of the box body 201 to realize the sealing contact between the two. Through this structure, when the fuselage 1 is laid flat, the anti-reverse valve 232 can prevent the sewage in the lower space 205 from flowing through it and entering the upper space 204 . In addition, the seal between the edge of the dividing plate 203 and the side wall of the box body 201 will also prevent the sewage in the lower space 205 from entering the upper space 204 from the gap between the edge of the dividing plate 203 and the side wall of the box body 201 . By setting in this way, it is also possible to prevent the sewage from returning to the upper space 204 and being sucked into the motor, and the cleaning device 100 can be used flat. In addition, when cleaning the dirt storage tank 4, when the partition plate 203 can be taken out from the box body 201, the first hole group 231 will filter out the solid waste in the sewage, that is, the sewage is stored in the box body 201, and the solid waste Carried on the partition plate 203, the separation of solid waste and sewage is realized. The solid waste can then be poured into the waste basket separately, while the sewage can be poured into the drain such as the toilet or sink, thereby effectively preventing the drain such as the toilet or sink from clogging. In addition, the partition plate 203 with the first hole group 231 and the anti-reverse valve 232 has a simple structure, simple manufacturing process and low cost, and is convenient to be used in the cleaning device 100 .

In some embodiments, the first hole set 231 may include one or more first through holes. In some embodiments, in order to improve the efficiency of sewage flowing from the upper space 204 into the lower space 205 , the number of first through holes in the first hole group 231 may be between 50-200. In some embodiments, in order to ensure the structural strength of the partition plate 203 , the number of first through holes in the first hole group 231 may be between 70-150. In some embodiments, the number of first through holes in the first hole group 231 may be between 80-120.

In some embodiments, the first through hole may be a through hole having a regular or irregular shape, such as a strip hole, a circular hole, or the like. Preferably, the first through hole is a strip hole, and the length and width ratio of the strip hole is large, which can not only ensure the efficiency of sewage passing through the first hole group 231, but also effectively prevent solid waste from passing through the first through hole, so that the partition plate 203 Has a better filtering effect. In some embodiments, when the first through hole is a strip hole, in order to ensure that the partition plate 203 has a better filtering effect, solid waste cannot pass through the first hole group 231, and the aspect ratio of the strip hole can be between Between 0.5 and 2. In some embodiments, the aspect ratio of the strip-shaped holes may be between 0.7 and 1.5. In some embodiments, the aspect ratio of the strip-shaped holes may be between 0.8 and 1.2.

In some embodiments, the area of the first through holes in the first hole group 231 can be 80 mm ² -100 mm ² , which can not only ensure that the efficiency of sewage passing through the first hole group 231 is improved, but also better block Solid waste, play a better filtering role. In some embodiments, the area of the first through hole in the first hole group 231 may be 85mm ² -100mm ² . The area of the first through holes in the first hole group 231 may be 90mm ² -100mm ² . In some embodiments, the area of the first through hole in the first hole group 231 may be 98 mm ² , which can better improve the efficiency of sewage passing through the first hole group 231 and block solid waste.

Since the first hole group 231 is arranged on the dividing plate 203, the area ratio of the first hole group 231 on the dividing plate 203 (that is, the total area of the first through holes in the first hole group 231 and the area ratio of the dividing plate 203 The ratio between the areas) is related to the structural strength of the partition plate 203 . In order to ensure that the partition plate 203 has a better structural strength and that the sewage passes through the first hole group 231 with a higher efficiency, in some embodiments, the area ratio of the first hole group 231 on the partition plate 203 can be between Between 0.1 and 0.5. In some embodiments, the area ratio of the first hole group 231 on the partition plate 203 may be between 0.1˜0.4. In some embodiments, the area ratio of the first hole group 231 on the partition plate 203 may be between 0.2-0.3.

In some embodiments, in order to take out the partition board 203 from the box body 201 conveniently, the partition board 203 is detachably installed in the box body 201 . In some embodiments, as shown in FIG. 10 , a handle 207 is disposed on the partition plate 203 , and the handle 207 extends toward the opening of the box body 201 (ie, the end where the cover body 216 is disposed). In this way, when the dirt storage tank 4 is cleaned, the user can easily lift the partition plate 203 from the casing 201 by lifting the handle 207, and at the same time, the solid waste carried on the partition plate 203 will be removed from the casing 201. It can be taken out from inside, so as to realize the separation of solid waste and sewage. In some embodiments, the partition plate 203 may also be directly connected to the cover body 216 . In this way, when the cover body 216 is removed, the partition plate 203 will be taken out at the same time. Can prevent like this when dumping the sewage in the sewage storage tank 4, because forgetting to take off the separating plate 203 causes the situation that sewage and solid waste mix again.

In some embodiments, the divider panel 203 may include an arc panel. In some embodiments, the partition plate 203 may be a curved panel protruding toward the lower space, and the first hole group 231 may deviate from the lowest point of the partition plate 203 . Wherein, the lowest point of the partition plate 203 may refer to the position on the upper or lower surface of the partition plate 203 with the smallest distance from the floor brush 2 . The deviation of the first hole group 231 from the lowest point of the partition plate 203 may mean that there is a distance between the position of the first hole group 231 and the lowest point of the partition plate 203 in the radial direction of the partition plate 203 . By setting the partition plate 203 as a protruding arc panel, the solid waste can be concentrated at the lowest point of the partition plate 203, thereby reducing the probability of the first hole group 231 being blocked by solid waste, which further facilitates the use of users Cleaning device 100 .

In some embodiments, as shown in FIG. 10 , a second hole group 210 is further provided on the partition plate 203 , and the second hole group 210 freely passes through the upper space 204 and the lower space 205 . During use, sewage can flow into the lower space 205 through the first hole group 231, and the air in the lower space 205 can flow to the upper space 204 through the second hole group 210 and then be sucked away by the motor (for example, the motor 34) , so that the pressure difference between the upper space 204 and the lower space 205 can be increased, so that the sewage can flow from the upper space 204 to the lower space 205 smoothly. In some embodiments, part of the sewage in the upper space 204 can flow into the lower space 205 from the second hole group 210 . Therefore, the second hole group 210 can also function to filter solid waste in sewage. In some embodiments, the second hole group 210 may deviate from the first hole group 231 in the circumferential direction of the partition plate 203 . In some embodiments, the deviation between the second hole group 210 and the first hole group 231 in the circumferential direction of the partition plate 203 can be understood as the existence of a gap between the second hole group 210 and the first hole group 231 in the circumferential direction of the partition plate 203 spacing. Wherein, the circumferential direction of the partition plate 203 may refer to the direction along the edge of the partition plate 203 . By setting in this way, when the cleaning device 100 is used in a flat position, the anti-reverse valve 232 is closed, and the water level of the sewage in the lower space 205 will be lower than the second hole group 210, so that the sewage in the lower space 205 will not pass through the second hole. Group 210 flows to headspace 204 . In some embodiments, the first hole set 231 may be diametrically opposite the second hole set 210 . In some embodiments, the fact that the first hole group 231 is radially opposite to the second hole group 210 can be understood as the position of the first hole group 231 and the second hole group 210 in the radial direction of the partition plate 203 relative to the geometry of the partition plate 203 The center is centrosymmetric. This can ensure that the distance between the first hole group 231 and the second hole group 210 in the circumferential direction of the partition plate 203 is relatively large, even if there is more sewage in the lower space 205, the water level of the sewage will not be higher than that of the second hole group. The hole group 210 ensures that the sewage in the lower space 205 will not flow into the upper space 204 through the second hole group 210 . This further facilitates the user to use the cleaning device 100 . In some embodiments, the second hole set 210 may include one or more second through holes. In order to ensure that the efficiency of sewage passing through the second hole group 210 is improved, and at the same time, it can better block solid waste and play a better filtering role. In some embodiments, the second through holes in the second hole group 210 The area can be 350mm ² -400mm ² . In some embodiments, the area of the second through holes in the second hole group 210 may be 360 mm ² -390 mm ² . In some embodiments, the area of the second through holes in the second hole group 210 may be 370 mm ² -380 mm ² . In some embodiments, the area of the second through holes in the second hole group 210 may be 376 mm ² , which can better improve the efficiency of sewage passing through the second hole group 210 and block solid waste.

In order to ensure that the partition plate 203 has a better structural strength and that sewage has a higher efficiency through the second hole group 210, in some embodiments, the area ratio of the second hole group 210 to the partition plate 203 (that is, the first The ratio between the total area of the second through holes in the two-hole group 210 and the area of the partition plate 203 ) may be between 0.01˜0.2. In some embodiments, the area ratio of the second hole group 210 to the partition plate 203 may be between 0.02˜0.1. In some embodiments, the area ratio of the second hole group 210 to the partition plate 203 may be between 0.05˜0.08.

In some embodiments, the second through holes in the second hole group 210 may have the same or different shape, number, etc. from the first through holes in the first hole group 231 . In some embodiments, for more descriptions about the number and shape of the second through holes in the second hole group 210, reference may be made to the relevant description about the number and shape of the first through holes in the first hole group 231, in This will not be repeated here.

In some embodiments, in order to prevent sewage from flowing from the lower space 205 to the upper space 204 when the cleaning device 100 is used tilted or flat, only the second hole group 210 may be set on the partition plate 203 without the first hole In this case, as long as the cleaning device 100 is arranged not to be inclined toward the direction of the second hole group 210 . For example, when the second hole group 210 is disposed on the partition plate 203 near the front side of the box body 201 , the cleaning device 100 can be tilted to the rear side during use. In some embodiments, when the partition plate 203 is configured as an arc panel, the second hole group 210 may deviate from the lowest point of the partition plate 203 . In this way, the probability of the second hole group 210 being blocked by solid waste can be reduced, thereby facilitating the user to use the cleaning device 100 .

In some embodiments, as shown in FIG. 10 , a blocking wall 211 may be erected along the circumferential direction of the partition plate 203 , and the blocking wall 211 may at least extend into the upper space 204 . When the partition board 203 is lifted out of the box body 201 , the blocking wall 211 can prevent solid waste from falling into the box body 201 from the edge of the partition board 203 . In some embodiments, drain holes can be set on the retaining wall 211, which not only prevents solid waste from falling, but also allows the sewage remaining on the partition plate 203 to be discharged into the box body 201 through the drain holes, thereby improving Separation effect of solid waste and sewage. In some embodiments, the support 212 can be erected along the circumference of the partition plate 203, and then the filter screen 213 can be provided on the support 212. The filter screen 213 can play the role of drain holes, thus forming the above-mentioned barrier with drain holes. wall 211. In some embodiments, when the partition plate 203 is provided with a blocking wall 211, the handle 207 can be connected to the blocking wall 211, or can be integrally formed with the blocking wall 211 (for example, the handle 207 can be extended upward by the bracket 212 part), which will not be repeated here.

In some embodiments, as shown in FIGS. 9 and 10 , an assembly hole 214 is also provided on the partition plate 203 . The assembly holes 214 deviate from the first hole group 231 and the second hole group 210 , that is, there is a gap between the assembly holes 214 and the first hole group 231 and the second hole group 210 in the radial direction of the partition plate 203 . The second channel 202 may be a pipe structure, and the second channel 202 may extend upward from the lower space 205 through the fitting hole 214 to the upper space 204 . In this way, the partition plate 203 can be assembled into the box body 201 conveniently. In some embodiments, the assembly hole 214 is in sealing contact with the second channel 202 (for example, a sealing ring can be provided between the edge of the assembly hole 214 and the second channel 202), preventing the edge of the assembly hole 214 from contacting the second channel 202. There is a gap between them to prevent sewage from flowing from the lower space 205 to the upper space 204 through the gap between the edge of the assembly hole 214 and the second channel 202 when the cleaning device 100 is laid flat.

In some embodiments, the second channel 202 can also be configured such that the sewage is opened on the side wall of the box body 201 and communicates with the upper space 204 . Wherein, the sewage opening can be understood as an opening through which sewage enters the box body 201 (upper space 204 ) along the second channel 202 . In an embodiment not shown, a top wall is provided on the top of the box body 201, and an opening for pouring sewage is provided on the top wall, and the cover body 216 can be covered on the opening; in this case, the first The sewage opening of the second channel 202 is opened on the top wall of the box body 201 and communicates with the upper space 204 .

In some embodiments, as shown in FIG. 10 , an annular baffle 215 may be provided along a side of the mounting hole 214 , and the annular baffle 215 may extend into the upper space 204 . With this structure, the second channel 202 can extend through the annular space formed by the annular baffle 215 , so that the connection between the partition plate 203 and the second channel 202 is more reliable. In this way, when the cleaning device 100 is tilted or laid flat, the angle between the dividing plate 203 relative to the axial direction of the second channel 202 is prevented from changing, that is, the dividing plate 203 (together with the blocking wall 211) does not move in the casing 201. In case of skewing, the anti-backflow structure 230 on the partition plate 203 remains in its original position, thereby ensuring that the sewage will not flow out from the lower space 205 through the anti-backflow structure 230 .

In some embodiments, when the joint 233 is elastic, the joint 233 can also be made of the same material as the valve body 234 . In some embodiments, the outer surface of the valve body 234 can be configured as a flat surface 235 , and the flat surface 235 will make the valve body 234 close (ie, the flat mouth is closed) under the pressure of the external environment. When the cleaning device 100 is used upright, as shown in Figure 12, the sewage from the upper space 204 enters the valve body 234 through the first hole group 231 and the conduit 208, and the pressure P1 of the sewage acts on the valve body 234, and the valve The body 234 is stretched (that is, the flat mouth is opened), and the sewage can flow into the lower space 205 for storage. When the cleaning device 100 is used in a flat position, as shown in Figure 13, the pressure P2 of the sewage in the lower space 205 acts on the plane 235 of the valve body 234, and the valve body 234 is pressurized so that the valve body 234 is closed, thus preventing The sewage in the lower space 205 flows out from the valve body 234 . At this time, the water temporarily stored in the upper space 204 is concentrated at the partition plate 203, away from the inlet 219 of the gas outflow channel 218, and the amount of water is very small, so it will not be drawn out from the box body 201, thus greatly reducing the motor stoppage. Probability of rotation or damage. In some embodiments, when the cleaning device 100 is used flat, if there is no or only a small amount of sewage in the lower space 205 and it is not enough to cause the anti-reverse valve 232 to close, the sucked sewage will also be temporarily stored in the upper space 204 and close to the partition. The plate 203 (part of the sewage may flow into the lower space 205), will not be drawn out from the box 201, thus the motor will not stall or be damaged.

In some embodiments, as shown in FIG. 14 , the anti-reverse valve 232 can also be an elastic valve plate 236 disposed on the lower surface of the partition plate 203 corresponding to the first hole group 231 . Wherein, the elastic valve sheet 236 can fit the partition plate 203 and cover the first hole set 231 to close the first hole set 231 so that the upper space 204 and the lower space 205 cannot communicate through the first hole set 231 . When the cleaning device 100 is used upright, under the pressure of the sewage in the upper space 204, the elastic valve plate 236 is pushed away towards the lower space 205 (as shown by the dotted line in Figure 14 is the elastic valve plate 236 after being pushed away ), the sewage can flow into the lower space 205 through the first hole group 231 for storage. When the cleaning device 100 is put down, the sewage in the lower space 205 can press the elastic valve plate 236 on the partition plate 203 and close the first hole group 231, which prevents the sewage in the lower space 205 from passing through the first hole Group 231 flows out.

As can be seen from the above, in order to ensure that the anti-reverse valve 232 can be fully opened when the sewage passes through the anti-reverse valve 232 and the sewage is located in the upper space 204 (for example, the valve body 234 is stretched or the elastic valve plate 236 is pushed away towards the lower space 205), So that sewage can flow into the lower space 205 from the upper space 204, and after the sewage flows into the lower space 205, the anti-reverse valve 232 can be completely closed (for example, the valve body 234 is closed or the elastic valve plate 236 fits with the partition plate 203 to close the first A set of holes 231), so that the sewage in the lower space 205 will not flow back to the upper space 204, and the valve body 234 or the elastic valve piece 236 needs to have better elastic deformation ability. In order to ensure that the valve body 234 or the elastic valve plate 236 has good elastic deformation ability, in some embodiments, the material used to make the valve body 234 or the elastic valve plate 236 may be rubber, silica gel and the like. In some embodiments, the valve body 234 or the elastic valve plate 236 can be made of rubber with a Shore hardness D ranging from 20 degrees to 80 degrees. In some embodiments, the valve body 234 or the elastic valve plate 236 can be made of rubber with a Shore hardness D between 40 degrees and 80 degrees. In some embodiments, the valve body 234 or the elastic valve piece 236 can be made of rubber with a Shore hardness D of 60-70 degrees. In some embodiments, the valve body 234 or the elastic valve piece 236 can 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, so that the valve body 234 or the elastic valve piece 236 has better deformation ability and better rigidity. In addition, silica gel has good corrosion resistance, which can prevent the valve body 234 or the elastic valve plate 236 from being corroded by sewage for a long time, resulting in reduced service life.

In some usage scenarios, when the temperature of the garbage inhaled by the cleaning device 100 is high, the temperature of the anti-reverse valve 232 will increase when the higher-temperature garbage passes through the anti-reverse valve 232, and the high temperature may affect the valve body 234 of the anti-reverse valve 232. Or the elasticity of the elastic valve plate 236 is affected, and the efficiency of sewage passing through the anti-reverse valve 232 is low. As an example, when the valve body 234 or the elastic valve plate 236 elastically descends, it will increase the difficulty of opening the anti-reverse valve (that is, the one-way conduction of the anti-reverse valve 232 from the upper space 204 to the lower space 205), so that sewage passes through the anti-reverse valve. The efficiency of the reverse valve 232 is reduced. In addition, excessive temperature may even cause ablation of the valve body 234 or the elastic valve plate 236 , thereby reducing the life of the anti-reverse valve 232 . In order to make the anti-reverse valve have better heat resistance, so that it can work normally at high temperature, in some embodiments, the heat resistance temperature of the material used to make the valve body 234 or the elastic valve piece 236 can be 25 ° C ~80°C. In some embodiments, the heat-resistant temperature of the material used to make the valve body 234 or the elastic valve piece 236 may be between 30°C and 70°C. In some embodiments, the heat-resistant temperature of the material used to make the valve body 234 or the elastic valve piece 236 may be between 40°C and 60°C.

In some embodiments, the anti-reverse valve 232 can also be a duckbill valve, a membrane check valve, an electromagnetic check valve or other types of check valves. In some embodiments, other types of anti-reverse valves or one-way valves can also be used to replace the anti-reverse valve 232 shown in FIG. within the scope of protection.

Fig. 15 is a schematic structural view of a cover according to some embodiments of the present specification.

In some embodiments, as shown in FIG. 8 and FIG. 15 , an adapter tube 217 may be provided in the box body 201 , and the cover 216 may abut against one end of the adapter tube 217 . Under the pressure of the cover body 216, the transfer pipe 217 can be more stable, and will not shake due to the impact of the sewage from the second channel 202, which is also the case when the sewage flow rate is fast.

In some embodiments, as shown in FIG. 8 , the other end of the transfer tube 217 may be connected to one end of the second channel 202 . Wherein, the other end of the transfer pipe 217 is the inlet 223 of the transfer pipe 217, and one end of the second passage 202 is the outlet 224 of the second passage 202, that is, the inlet 223 of the transfer pipe 217 can be combined with the outlet 224 of the second passage 202. Together. In some embodiments, the transfer tube 217 has an outlet 220 , and the outlet 220 of the transfer tube 217 may deviate from the cover 216 . For example, the transfer tube 217 is closed toward the end of the cover body 216 , and the outlet 220 may be disposed on a side wall of the transfer tube 217 . By opening the outlet 220 on the side wall of the adapter pipe 217, the movement path of the water-air mixture in the box body 201 can be extended, and the water-gas separation effect can be improved; in addition, it can also reduce the water being drawn into the gas outflow channel 218 and then reach Risks at the motor are reduced, thereby increasing the service life of the cleaning device 100 .

In some embodiments, the outlet 220 of the transfer pipe 217 deviates from the inlet 219 of the gas outflow channel 218 in the circumferential direction, that is, the inlet 219 of the gas outflow channel and the outlet 220 of the connecting pipe 217 are arranged in different directions. The transfer pipe 217 is on the side wall away from the inlet 219 . For example, the outlet 220 of the transfer pipe 217 is opposite to the inlet 219 of the gas outflow channel 218 in the radial direction of the transfer pipe 217, and the height of the outlet 220 is lower than the height of the inlet 219, which maximizes the distance between the outlet 220 and the inlet 219. The distance between them prolongs the movement path of the water-air mixture in the box 201 and improves the effect of gas-water separation. Where the outlet 220 and the inlet 219 are opposite in the radial direction of the transfer pipe 217 , it can be understood that the line between the outlet 220 and the inlet 219 intersects the axis of the transfer pipe 217 .

In some embodiments, the transfer tube 217 and the second channel 202 are integrated, that is, the transfer tube 217 may be a part of the second channel 202 . In this case, the transition pipe 217 may be a straight pipe with a diameter smaller than or equal to that of the second channel 202 so as to pass through the assembly hole 214 of the partition plate 203 conveniently.

In some embodiments, the transfer tube 217 and the second channel 202 are of separate structure, that is, the transfer tube 217 can be manufactured separately and then assembled with the second channel 202 . In this way, the second passage 202 can be manufactured as a straight pipe, and there is no need to consider the size relationship between the transfer pipe 217 and the assembly hole 214 , which simplifies the manufacture of the second passage 202 and the transfer pipe 217 .

In some embodiments, as shown in FIG. 15 , a water level probe set 240 may be disposed on the cover 216 , and the water level probe set 240 extends toward the lower space 205 . The water level probe set 240 can be used to monitor the sewage water level in the tank 201 . When the water level in the box body 201 reaches the preset threshold, the motor (for example, the motor 33 or the motor 34 ) in the cleaning device 100 will stop rotating, and remind the user to dump the sewage in the box body 201 in time. In some embodiments, the water level probe set 240 may employ a bipolar water level probe. In some embodiments, the water level probe set 240 can also adopt a monopole water level probe, or other forms of water level probes.

In some embodiments, continue referring to FIG. 15 , the water level probe set 240 includes a first probe set 241 and a second probe set 242 extending toward the lower space 205 . In some embodiments, the extension length of the first probe set 241 may be greater than the extension length of the second probe set 242 . In some embodiments, the second probe set 242 can extend into the upper space 204 and be directly above the first hole set 231 . The first probe set 241 can be used to monitor the water level in the tank 201 when the cleaning device 100 is used upright. When the water level in the tank 201 reaches the preset threshold, the motor will stop rotating and remind the user to dump the sewage in the tank 201 in time. The second probe set 242 can be used to monitor the water level in the tank 201 when the cleaning device 100 is laid flat and used. When the water level detected by the second probe set 242 reaches the preset threshold, the motor will stop rotating and remind the user to dump the sewage in time. As mentioned above, when the cleaning device 100 is used flat, the anti-backflow structure 230 arranged on the partition plate 203 will prevent the sewage in the lower space 205 from flowing back into the upper space 204 through it, so that the motor will not stop. , the cleaning device 100 can still perform cleaning work normally. At this time, the sewage sucked into the upper space 204 through the second channel 202 will accumulate in the upper space 204 at the partition plate 203 . When the sewage accumulated in the upper space 204 is too much and flows to the cover 216 , it will first flow to the second probe set 242 . The second probe 242 will generate a signal to instruct the motor to stop rotating, thereby preventing the sewage from being sucked into the motor and causing damage to the motor. Therefore, by setting the first probe set 241 and the second probe set 242, the water level in the tank 201 can be monitored in real time, so as to prevent the sewage from being sucked into the motor and causing damage to the motor. This greatly prolongs the service life of the cleaning device 100 .

In some embodiments, the first probe set 241 may extend into the lower space 205 . In other words, the first probe set 241 may extend through the partition plate 203 to the lower space 205 . In this way, before the sewage water level in the casing 201 (lower space 205 ) reaches the partition plate 203, the first probe set 241 will detect the threshold water level, so that the motor stops rotating. This can further prevent sewage from being sucked into the motor, prolonging the service life of the cleaning device 100 . In some embodiments, the depth to which the first probe set 241 goes deep into the lower space 205 can be adjusted according to the actual situation, for example, the first probe set 241 can be adjusted to go deep into the lower space according to the height of the partition plate 203 in the box body 201 205' in depth. In some embodiments, the higher the partition plate 203 is in the box body 201 , the deeper the first probe set 241 penetrates into the lower space 205 .

In some embodiments, the first probe set 241 can also be located in the upper space 204 and close to the partition plate 203 . According to this structure, when the partition plate 203 is blocked, the water level of the sewage in the lower space 205 is low, and the sewage is accumulated in the upper space 204, the first probe group 241 can still accurately monitor the water level of the sewage to prevent the sewage from being sucked inside the motor. In some embodiments, the position of the first probe set 241 in the upper space 205 can be adjusted according to actual conditions. In some embodiments, the first probe set 241 can also be extended into the lower space 205 or the upper space 204 according to the actual situation, or the first probe set 241 can be set in both the upper space 204 and the lower space 205 .

In some embodiments, the second probe set 242 may be located above the outlet 220 of the adapter tube 217 . In this way, the sewage coming out of the outlet 220 can be prevented from being directly sprayed onto the second probe set 242 , reducing the probability of misjudgment by the second probe set 242 .

In some embodiments, as shown in FIG. 15 , two baffles 243 extending into the upper space 204 may also be provided on the cover 216 , and the two baffles 243 are spaced apart in the circumferential direction of the cover 216 layout. At least a partial area of the side edge 244 of each baffle 243 is separated by the side wall of the box body 201 . The outlet 224 of the second channel 202 may be between the baffles 243 . The baffle plate 243 can guide the sewage splashed on it to flow downwards, so as to prevent the sewage from splashing around in the box body 201 , which will cause adverse effects on the use of the cleaning device 100 . In addition, the air sucked into the box body 201 from the second channel 202 needs to bypass the baffle plate 243 to reach the inlet 219 of the gas outflow channel 218 on the cover 216, thereby making the movement path of the water-air mixture more tortuous and prolonging the water-air mixture. The moving path of the mixture in the box body 201 improves the gas-water separation effect. As also shown in FIG. 15 , the second probe set 242 may also be located between the pair of baffles 243. This makes the structure of the cover body 216 more compact, which is beneficial to reduce the radial size of the dirt storage tank 4, making the cleaning device 100 smaller in size, simpler and more flexible, and convenient for cleaning a narrow space.

In some embodiments, the upper area 245 of the side edge 244 of the baffle 243 is in contact with the side wall of the box body 201, the lower area 246 is spaced apart from the side wall of the box body 201, and the outlet 224 of the second channel 202 is set to correspond to on the upper region 245 of the side edge 244 . Through this structure, the baffle plate 243 can not only prevent the sewage from splashing around in the box body 201, but also force the water-air mixture to deflect downward to cross the baffle plate 243, so that the movement path of the water-air mixture in the box body 201 Longer, better air-water separation.

In some embodiments, a back plate 247 can also be provided on the cover body 216, and the back plate 247 can be located between the inlet 219 of the gas outflow channel 218 and the adapter pipe 217 (outlet 220), and the back plate 247 can be connected between the two Between the baffles 243 . Through this structure, the water-air mixture will flow down and cross the back plate 247 before reaching the inlet 219 of the gas outflow channel 218, which also helps to extend the movement path of the water-air mixture in the box 201, and the gas-water separation effect is also improved. better. In some embodiments, the extended length of the back plate 247 may be less than the extended length of the baffles 243 . Wherein, the extension length of the back plate 247 and the baffle 243 may refer to the dimensions of the back plate 247 and the baffle 243 along the length direction of the fuselage 1 . This can prevent the baffle plate 243 and the back plate 247 from excessively blocking the path of the water-air mixture, so as to ensure smooth airflow and better cleaning effect when the cleaning device 100 is used. In order to effectively extend the moving path of the water-air mixture in the box body 201 , in some embodiments, the extension length of the back plate 247 may be 50mm˜100mm. In some embodiments, the extension length of the back plate 247 may be 60mm˜100mm. In some embodiments, the extension length of the back plate 247 may be 70mm-95mm. In some embodiments, the extension length of the back plate 247 may be 75mm-90mm. In order to prevent the baffle plate 243 and the back plate 247 from excessively blocking the path of the water-air mixture, in some embodiments, the difference between the extension length of the baffle plate 243 and the extension length of the back plate 247 may be 25 mm˜40 mm. In some embodiments, the difference between the extended length of the baffle 243 and the extended length of the back plate 247 may be 28mm˜37mm. In some embodiments, the difference between the extended length of the baffle 243 and the extended length of the back plate 247 may be 30mm˜35mm.

In some embodiments, when the transfer pipe 217 is separated from the second channel 202, a water baffle (not shown in the figure) may also be provided between the outlet 220 of the transfer pipe 217 and the bottom of the second probe set 242. Shows). The water baffle may be in contact with the sidewall of the box body 201 . By setting the water baffle, the water baffle can separate the second probe set 242 from the outlet 220 of the transfer pipe 217, thereby more effectively preventing sewage from being directly sprayed on the second probe set 242, and further reducing errors. probability of judgment.

In some embodiments, as shown in FIG. 16 , an installation area 250 cooperating with the fuselage 1 is provided on the circumferential outer surface of the box body 201 , and the anti-backflow structure 230 is away from the installation area 250 in the radial direction of the partition plate. Viewed from the cleaning device 100 as a whole, the installation area 250 may be located at the front side of the box body 201 , while the anti-backflow structure 230 is close to the rear side of the box body 201 in the box body 201 (as shown in FIGS. 1-4 ). Through the above settings, when the cleaning device 100 is laid flat (as shown in Figures 17 and 18), the anti-backflow structure 230 is closed and is at the lower position of the second hole group 210, so that the sewage in the lower space 205 can be prevented from flowing through it and entering In the upper space 204, the cleaning device 100 can also be used normally. In some embodiments, in other types of cleaning devices, the dirt storage tank 4 can also be arranged in front of the fuselage 1 (as shown in FIGS. It only needs to match the installation position of the anti-backflow structure 230 , and details will not be repeated here. In addition, it should be noted that, as shown in FIG. 18 , the dirt storage tank 4 is arranged on the front side of the fuselage 1 , and the anti-backflow structure 230 is close to the installation area 250 in the radial direction of the partition plate 203 . Thus, when the cleaning device 100 is laid flat (as shown in FIG. 18 ), the anti-backflow structure 230 is closed and is at the low position of the second hole group 210, so that the sewage in the lower space 205 can be prevented from flowing through it and entering the upper space 204. , the cleaning device 100 can be used normally.

Different use scenarios of the cleaning device 100 will be described below in conjunction with FIG. 4 and FIG. 17 . Referring to Fig. 4, Fig. 4 shows the cleaning device 100 in the first usage scenario. The first usage scenario may include a situation when a user uses the cleaning device 100 upright. When the user uses the cleaning device 100 upright, the motor 34 rotates, and after starting the water spray system (for example, the cleaning liquid supply assembly mentioned above), clean water is sprayed from the cleaning liquid tank to the ground. The sewage on the ground is sucked by the ground brush 2 and then sucked into the upper space 204 of the box body 201 through the first channel 6 and the second channel 202 . The sewage flows into the lower space 205 for storage through the first hole group 231 (and the anti-reverse valve 232 ) and/or the second hole group 210 on the partition plate 203 . The solid waste in the sewage is filtered by the partition plate 203 and left in the upper space 204 . When the first probe set 241 detects that the sewage water level in the tank 201 reaches the threshold, the motor 34 stops rotating and reminds the user, for example, to remind the user to dump the sewage in the tank 201 in time.

Referring to Fig. 17, Fig. 17 shows the cleaning device 100 in the second usage scenario. The second usage scenario may include a situation where the user uses the cleaning device 100 on a flat (or tilted) basis. When the user lays the cleaning device 100 flat, the sewage in the lower space 205 cannot reach the upper space 204 under the action of the anti-backflow structure 230 on the partition plate 203 , but remains in the lower space 205 . The motor 34 rotates, and after starting the water spray system, clean water is sprayed to the ground from the clean water tank, and sewage is sucked into the upper space 204 of the casing 201 through the second channel 202 again. At this time, the sewage is temporarily stored in the upper space 204, the motor 34 rotates normally, and the cleaning device 100 is used normally. When the second probe set 242 detects that the temporarily stored sewage water level in the upper space 204 reaches the threshold, the motor 34 stops rotating and reminds the user. When the cleaning device 100 is erected, the sewage temporarily stored in the upper space 204 will flow into the lower space 205 through the first hole group 231 (and the anti-reverse valve 232) and/or the second hole group 210.

Fig. 19 is a first cross-sectional schematic diagram of a dirt storage tank according to some embodiments of the present specification. Fig. 20 is a second schematic cross-sectional view of a dirt storage tank according to some embodiments of the present specification. In some embodiments, the dirt storage tank 4 in the cleaning device 100 shown in FIGS. 1-7 may specifically be the dirt storage tank 300 shown in FIGS. 19 and 20 .

As shown in FIGS. 19 and 20 , the dirt storage tank 300 may include a tank body 301 and a sewage pipe 302 . Wherein, the sewage pipe 302 may be the second passage 202 in the sewage storage tank 4 shown in FIG. 8 , or the sewage pipe 302 may at least include the second passage 202 in the sewage storage tank 4 shown in FIG. 8 . The casing 301 includes a bottom surface 303, the bottom surface 303 is provided with a sewage inlet 304, the sewage pipe 302 is formed by extending upward from the sewage inlet 304, and the upper part of the sewage pipe 302 is provided with a sewage outlet 3021, and the fluid M entering from the sewage pipe 302 is discharged at the sewage outlet 3021. The separation of mixed liquid a and mixed gas c, the mixed liquid a separated from the sewage outlet 3021 flows downward due to its own gravity and is stored at the bottom of the tank 301, thereby realizing the first filtering method of the sewage storage tank 300: mixing Separation of liquid a from mixed gas c. In some embodiments, the sewage inlet 304 can be arranged on the side of the box body 301, and the box body 301 is provided with a cyclone filter assembly 305, and the dust entering from the sewage inlet 304 can be separated by the cyclone filter assembly 305, for example, The mixed liquid a and the mixed gas c are separated.

In some embodiments, continue referring to FIG. 19 and FIG. 20 , the dirt storage tank 300 may further include a cover 306 and a cyclone filter assembly 305 . In some embodiments, the cyclone filter component 305 may be the cyclone separation structure 260 as shown in FIG. 8 , or a component having a structure similar to the cyclone separation structure 260 or achieving the same function. Alternatively, the cyclone separation structure 260 shown in FIG. 8 may be a part of the cyclone filter assembly 305 . The cover 306 may include a cover body 3061, the cover body 3061 may be inserted into the upper end of the box body 301, the cover body 3061 is provided with an air inlet 3062, and the cyclone filter assembly 305 may be arranged on the cover body 3061 and The air inlet 3062 is connected, and the air inlet 3062 is located above the sewage outlet 3021 . In some embodiments, the air inlet 3062 may be the inlet 219 shown in FIG. 8 , or a structure having a similar structure or the same function as the air inlet 219 . The mixed gas c separated from the sewage outlet 3021 continues to move upwards to the air inlet 3062 and enters the cyclone filter assembly 305 due to its lighter quality. The cyclone filter assembly 305 filters the mixed gas c, and the dust d in the mixed gas c remains In the cyclone filter assembly 305, under the action of the vacuum environment formed by the operation of the motor, the filtered clean gas e is discharged from the cyclone filter assembly 305 and passed through the motor in the cleaning device 100 (for example, the motor in the motor 34 or the hand-held vacuum cleaner 3 33) discharge to the outside of the cleaning device 100, thereby avoiding the gas discharged from the motor from containing more dust d, ensuring the cleanliness of the external environment, and avoiding respiratory diseases caused by the operator inhaling too much dust d, To ensure the health of the operator, the second filtering method of the dirt storage tank 300 is realized: the separation of clean gas e and dust d.

In some embodiments, as shown in FIG. 21, the air inlet 3062 can be arranged adjacent to the sewage outlet 3021, but this may cause a part of the mixed liquid a sprayed from the sewage pipe 302 to be sprayed into the air inlet 3062, due to the cyclone The filter assembly 305 cannot filter moisture, and the moisture entering the air inlet 3062 will enter the cyclone filter assembly 305, Hypa and the motor in turn. The gas with moisture will easily reduce the air permeability of the Hypa, and the humid environment will easily make the Hypa Breed bacteria. Among them, Hypa is a high-efficiency filter (filter paper) commonly used in cleaning devices, which can be used to filter 99% of fine particles in the air, so that the air passing through the cleaning device can be purified and removed to reduce secondary pollution. In addition, the moisture-laden gas may be sucked into the motor, causing a short circuit in the motor, resulting in failure of the cleaning device 100 .

In order to solve the above problems, as shown in Figure 19, the sewage outlet 3021 and the air inlet 3062 can be located on both sides of the central axis 3012 of the box body 301, and there is a certain distance between the sewage outlet 3021 and the air inlet 3062, which can prevent the mixed liquid a from directly The problem of splashing from the sewage outlet 3021 to the air inlet 3062. After the mixed gas c is discharged from the sewage outlet 3021, it walks a long path before entering the air inlet 3062.

In some embodiments, as shown in Fig. 19, Fig. 20 and Fig. 25, the dirt storage tank 300 also includes a filter mechanism 307 arranged in the box body 301, and the filter mechanism 307 is arranged along the vertical direction (that is, the length direction of the fuselage 1) ) is located between the sewage outlet 3021 and the bottom surface 303, the mixed liquid a flows through the filter mechanism 307, the dry garbage f in the mixed liquid a stays on the filter mechanism 307, and the wet garbage b in the mixed liquid a flows into the filter mechanism 307 and the bottom surface 303 In the space between, the filter mechanism 307 can separate the mixed liquid a from the dry garbage f and the wet garbage b, which is convenient for the user to clean the dirt storage tank 300 better, thereby realizing the third filtering method of the dirt storage tank 300 .

In some embodiments, as shown in Figure 19 and Figure 20, since the filter mechanism 307 is between the bottom surface 303 of the box body 301 and the cyclone filter assembly 305, the filter mechanism 307 can also have a certain degree of wet garbage b stored below it. The blocking effect prevents the wet garbage b caused by the vibration of the dirt storage tank 300 from splashing to the position of the air inlet 3062, avoids water ingress in the Hypa and the motor, and avoids a short circuit in the motor.

A cleaning device with a dirt storage tank 300 (such as the cleaning device 100 shown in Figures 1 to 7) can realize three filtering methods at the same time. Consumers only need to buy one cleaning device 100 to clean different environments. To one machine with multiple functions, consumers do not need to switch between multiple cleaning devices with different functions or other cleaning devices, and the operation of the cleaning device with the dirt storage tank 300 is simple and convenient.

In some embodiments, as shown in FIG. 19 , the sewage outlet 3021 can be arranged on the side of the sewage pipe 302 and facing the inner wall of the box body 301 , and the mixed liquid a sprayed from the sewage outlet 3021 flows along the side of the box body 301 . During the flow of the inner wall, a part of the dry garbage f will remain on the inner wall of the box body 301, thereby further improving the separation effect of the dry garbage f and the wet garbage b of the mixed liquid a. The upper dry garbage f is air-dried to a certain extent, and the dry garbage f will drop from the inner side wall of the box body 301 to the filter mechanism 307 .

In some embodiments, as shown in Figure 25 and Figure 27, the transfer pipe 3023 is connected to the filter mechanism 307, when the operator removes the cover 306 from the box body 301, the operator can hold the ash bucket 3066 The effect of removing the ash bucket 3066 and the transfer pipe 3023 from the box body 301 is achieved, which is convenient for the operator to clean the ash bucket 3066, the transfer pipe 3023 and the filter mechanism 307 and has a better cleaning effect. By setting in this way, it is not necessary to set a long rod connected with the filter mechanism 307 , thereby simplifying the structure of the dirt storage tank 300 .

In some embodiments, as shown in FIG. 25 and FIG. 27 , the transfer tube 3023 is pivotally connected to the filter mechanism 307. The operator holds the transfer tube 3023 and rotates the filter mechanism 307 relative to the transfer tube 3023 so that the axis of the transfer tube 3023 is in line with the filter mechanism 3023. The axis of the filter mechanism 307 is arranged at 90 degrees, and a portion of the transfer pipe 3023 protrudes from the periphery of the filter mechanism 307 . Since the outer periphery of the transfer pipe 3023 is relatively clean, when the operator cleans up the dry garbage f in the filter mechanism 307, the inner surface of the filter mechanism 307 faces downward, and the operator holds the transfer pipe 3023 protruding from the peripheral part of the filter mechanism 307 , Like this, the dry rubbish f in the filtering mechanism 307 falls along the vertical direction and can not dirty user's hand.

Since the working environment of the cleaning device 100 is different, for example, there are scenes of cleaning large-volume dry garbage such as shredded paper and hair, and scenes of cleaning mud soup with a lot of dust, the operator can select the filter screen 30722 according to different scenes The size of the first filter hole 4221 can be adjusted to match different scenes, and the versatility of the dirt storage tank 300 can be improved. In some embodiments, the filter 30722 can be the filter 213 shown in FIG. 10 , or a component that has a similar structure or achieves the same function as the filter 213 .

In some embodiments, as shown in FIG. 19 , FIG. 25 and FIG. 27 , the filter screen 30722 can protrude outward, so that the storage space inside the filter basket 3072 is larger, so that the filter basket 3072 can store more dry garbage. Storage and recovery. In some embodiments, the filter screen 30722 can be made of metal plate or filter cloth, wherein the filter cloth can filter finer dust particles, and the metal plate has better strength and hardness, which can effectively improve the service life of the filter screen 30722 . In addition, the convex filter screen 30722 installed in the installation port 30724 with the same area has a larger surface area, and the number of first filter holes 30725 on the convex filter screen 30722 is more, which can improve the mixed liquid a. Dry garbage f and wet garbage b separation efficiency.

In some embodiments, the structure of the supporting frame 30721 is described in conjunction with Fig. 25 and Fig. 27. As shown in Fig. 25 and Fig. 27, the supporting frame 30721 includes a partition 30726 and an annular side peripheral plate 30727, and the partition 30726 is provided with There are a plurality of second filter holes 30728, the annular side peripheral plate 30727 is connected with the partition plate 30726 and constitutes an accommodating space with the partition plate 30726, and a plurality of mounting holes arranged at intervals along the circumferential direction are provided on the annular side peripheral plate 30727 Port 30724, filter screen 30722 are connected end to end to form a ring structure, the outer surface of part of the filter screen 30722 is in contact with the inner surface of the annular side peripheral plate 30727, and multiple installation ports 30724 can be realized by only one filter screen 30722 The plugging can improve the user's quick assembly of the filter basket 3072 and improve the disassembly efficiency of the filter basket 3072. In some embodiments, the partition 30726 may be the partition 203 shown in FIG. 10 , or a component that has a similar structure or performs the same function as the partition 203 . In some embodiments, the annular side peripheral plate 30727 can be the bracket 212 shown in FIG. 10 , or a component that has a similar structure or achieves the same function as the bracket 212 . In some embodiments, the combination of annular side perimeter plate 30727 and bracket 212 may be referred to as a barrier (eg, barrier 211 shown in FIG. 10 ).

In some embodiments, as shown in Figure 22, the distance between the partition 30726 and the bottom surface 303 of the box 301 is L5, the height of the box 301 is H, and L5/H is 1/3 to 1/2, that is In other words, 1/3˜1/2 of the volume of the box body 301 can be used to store wet garbage b, which can realize the storage of more wet garbage b by the cleaning device 100 .

In some embodiments, as shown in FIG. 25 , the height of the annular side peripheral plate 30727 can be 20 mm to 50 mm. Compared with the support frame 30721 with only the partition plate 30726, the annular side peripheral plate 30727 of the filter basket 3072 has a certain The height can achieve the effect of increasing the accommodating space for storing dry garbage (dry garbage f shown in FIG. 19 ), thereby realizing the effect of the filter basket 3072 storing more dry garbage.

In some embodiments, as shown in Figure 20 and Figure 25, the second filter holes 30728 are elongated holes, and a plurality of second filter holes 30728 are evenly arranged around the center line of the partition 30726, which can realize wet garbage (Figure 19 The wet garbage shown in b) evenly flows down at each position of the partition plate 30726 to avoid blockage of some of the second filter holes 30728 caused by uneven distribution of the second filter holes 30728 and improve the solid-liquid separation efficiency of the filter basket 3072.

In some embodiments, as shown in Figure 20 and Figure 25, a through hole 30729 is opened in the middle of the partition 30726, and the pipe body 3022 is connected to the adapter pipe 3023 through the through hole 30729, so that when the cleaning device is tilted or laid flat When 100, the filter basket 3072 will not be skewed in the casing 301. In some embodiments, the through hole 30729 may be the assembly hole 214 shown in FIG. Parts with the same function in the dirt storage tank 4 shown.

Further, the through hole 30729 extends upwards to form a conduit 30730, the tube body 3022 is inserted into the conduit 30730, and the outer peripheral surface of the tube body 3022 abuts against the inner wall of the conduit 30730, which can increase the contact area between the filter basket 3072 and the tube body 3022, and can Further avoid that the filter basket 3072 is not crooked in the box body 301 . In some embodiments, the conduit 30730 may be the annular baffle 215 shown in FIG. 10 , or a component having a similar structure or performing the same function as the annular baffle 215 .

In some embodiments, as shown in FIG. 19 , FIG. 20 and FIG. 25 , the outer peripheral surface of the tube body 3022 is in interference fit with the inner wall of the conduit 30730 , which can achieve a better fixing effect between the filter basket 3072 and the tube body 3022 and avoid filter basket 3072 . The basket 3072 slides down to the bottom surface 303 of the casing 301 to prevent the filter basket 3072 from contacting again with the wet garbage b that has filtered out the dry garbage f, and to ensure that the dry garbage f and the wet garbage b are independently set. Specifically, the diameter of the tube body 3022 gradually decreases from bottom to top, and the outer diameter of the tube body 3022 at the middle position is the same as the inner hole diameter of the conduit 30730, which can ensure that the filter basket 3072 is in the same position as the tube body at the middle position of the tube body 3022. 3022 fixed. In addition, the diameter of the upper end of the pipe body 3022 is smaller than the diameter of the inner hole of the conduit 30730 , which is also convenient for the operator to install the filter basket 3072 on the pipe body 3022 .

Deposition of spacer 30726. In addition, when the projected area of the partition 30726 on the horizontal plane is constant, the above structure can increase the overall surface area of the partition 30726, and the total area of the plurality of second filter holes 30728 is larger, which can improve the separation between dry garbage f and wet garbage b. separation efficiency.

In some embodiments, as shown in FIG. 19 , the edge of the upper end of the annular side peripheral plate 30727 is in sealing contact with the inner peripheral surface of the box body 301 . By setting in this way, first of all, large particles or large-volume dry garbage f cannot pass through the gap between the edge of the upper end of the annular side peripheral plate 30727 and the inner peripheral surface of the box body 301, so that large particles or large-volume dry garbage f f stays in the filter mechanism 307 after the filter mechanism 307 is separated, so as to prevent large particles or bulky dry garbage f from entering the wet garbage b in the filter mechanism 307 . In addition, the wet garbage b between the filter mechanism 307 and the bottom surface 303 will not pass through the gap between the edge of the upper end of the annular side peripheral plate 30727 and the inner peripheral surface of the box body 301, and the gap between the filter mechanism 307 and the bottom surface 303 can be completely avoided. There is a risk that the wet garbage b in between will enter the filter mechanism 307 due to vibration. Of course, since the edge of the upper end of the annular side peripheral plate 30727 is in sealing contact with the inner peripheral surface of the box body 301 , even if the dirt storage tank 300 vibrates, the relative displacement between the filter basket 3072 and the box body 301 can be avoided.

In some embodiments, as shown in Figure 19, the cross-sectional area of the annular side peripheral plate 30727 gradually decreases from top to bottom, so that there is a gap between the filter screen 30722 and the inner peripheral surface of the box body 301, and the wet garbage b can enter the space between the filter mechanism 307 and the bottom surface 303 through the first filter hole 4221 on the filter screen 30722, and improve the separation efficiency of the mixed liquid a for dry garbage f and wet garbage b.

For the convenience of understanding, the working principle of the dirt storage tank 300 under three different working conditions will be described with reference to FIG. 19 .

In some embodiments, as shown in FIG. 19 , when the cleaning device with the dirt storage tank 300 (for example, the cleaning device 100 shown in FIGS. 1 to 7 ) only performs dust suction, the fluid M only includes dust and air. Part of the dust in the fluid M discharged from the sewage outlet 3021 moves downward and falls in the filter basket 3072, and the other part of the dust is mixed with air to form a mixed gas c that enters the cyclone filter assembly 305 through the air inlet 3062, and the dust d stays in the dust accumulation In the barrel 3066, the clean gas e is discharged from the cyclone filter assembly 305.

In some embodiments, as shown in FIG. 19 , when the cleaning device with the dirt storage tank 300 (for example, the cleaning device 100 shown in FIGS. 1 to 7 ) only performs water absorption, the fluid M only includes water and air, The water in the fluid M discharged from the sewage outlet 3021 will move downwards and be stored at the bottom of the tank 301, thereby realizing the recovery of sewage. The air mixed in the fluid M passes through the air inlet 3062 and the cyclone filter assembly 305 in turn, and then is discharged from the cyclone filter assembly 305 .

In some embodiments, as shown in FIG. 19, when a cleaning device with a dirt storage tank 300 (for example, the cleaning device 100 shown in FIGS. 3021 separates the mixed liquid a from the mixed gas c, the mixed liquid a has a general downward movement trend, and the mixed liquid a separates the dry garbage f from the wet garbage b (or called liquid garbage) at the filter mechanism 307, and the dry garbage Garbage f remains in the filter mechanism 307, and wet garbage b enters the bottom of the box body 301. The mixed gas c is separated from the clean gas e and the dust d in the cyclone filter assembly 305 , the dust d remains in the ash bucket 3066 , and the clean gas e exits the cyclone filter assembly 305 through the air outlet 30511 .

In some embodiments, the cover 306 of the dirt storage tank 300 may not be provided with the ash bucket 3066 . Specifically, as shown in FIG. 33 , the cover 306 may include a first shielding plate 30615, and the first shielding plate 30615 is pivotally connected to the cover body 3061. When the cover body 3061 is plugged into the box body 301, the The top end abuts against the first baffle plate, so that the first baffle plate 30615 blocks the ash outlet 30613, and dust (for example, dust d shown in FIG. 19 ) can be stored in the cover body 3061 and the first baffle plate 30615. between. When the cover 306 is removed from the box body 301, the first shielding plate 30615 is rotated relative to the air duct of the cyclone filter mechanism 3053 by gravity, thereby realizing the opening of the ash discharge port 30613, and the dust in the ash storage space can pass through the ash discharge port 30613 automatically falls into the filter basket 3072 below, and the operator can clean the filter basket 3072 to clean up the dust and dry rubbish (for example, the dry rubbish f shown in Figure 19 ) at the same time.

In some embodiments, the first shielding plate 30615 can be connected to the cover body 3061 through a pivot shaft, and a torsion spring is sleeved on the pivot shaft, and the two ends of the torsion spring are connected to the first shielding plate 30615 and the cover body respectively. 3061 are in contact with each other. When the cover 306 is removed from the box body 301, the elastic recovery force of the torsion spring can realize the automatic opening of the ash discharge port 30613 by the first shielding plate 30615, so that the dust can fall into the filter basket 3072 better. In some embodiments, when the torsion spring is in a natural state, the first shielding plate 30615 is 60 degrees from the plane where the ash discharge port 30613 is located. A baffle plate 30615 blocks the ash discharge port 30613.

In some embodiments, as shown in FIG. 33 , the sewage pipe 302 is integrally formed, which can improve the processing efficiency of the sewage pipe 302 .

In some embodiments, as shown in FIG. 33 , since the cover 306 cancels the setting of the ash bucket 3066 , the inside of the box 301 can have a larger free space, and the baffle 3063 can be arranged in a ring shape and surround the Around the outer circumference of the sewage pipe 302 near the sewage outlet 3021, the area of the baffle 3063 at the outer circumference of the sewage pipe 302 is larger, and more of the mixed liquid (for example, the mixed liquid a shown in Figure 19) can be realized. The dry garbage remains on the solid surface of the baffle 3063 to achieve a better separation effect on dry garbage and wet garbage (eg, wet garbage b shown in FIG. 19 ) in the mixed liquid.

In some embodiments, the structure of the filter mechanism 307 shown in FIG. 34 may be slightly different from the filter mechanism 307 in other embodiments of this specification (for example, the filter mechanism 307 shown in FIG. 19 ), the main difference between the two is 33 and 34, the filter mechanism 307 may include a handle 3073 and a filter basket 3072, the filter basket 3072 is connected to the handle 3073, and the distance between the upper end surface of the handle 3073 and the opening 308 along the vertical direction is 10mm ~20mm, when the cover 306 is removed from the box body 301, the user can take out the filter basket 3072 from the box body 301 by holding the handle 3073. The filter mechanism 307 has a simple structure and is convenient for the user to operate.

In some embodiments, as shown in FIG. 34 , the handle 3073 includes a connecting rod 30731 and a handle 30732. One end of the connecting rod 30731 is connected to the filter basket 3072, and the handle 30732 is connected to the other end of the connecting rod 30731. The width of the hand 3073 is greater than the width of the connecting rod 30731, and the handle 30732 is arranged to facilitate the operator to hold and apply 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 with the other end of the connecting rod 30731, the first side plate 30734, the second The two side plates 30735 and the third side plate 30736 are perpendicular to the connecting plate 30733 and located on one side of the connecting plate 30733, the first side plate 30734 and the third side plate 30736 are connected to the two sides of the second side plate 30735, the first side The distance between the board 30734 and the third side board 30736 gradually increases from bottom to top, and the inverted trapezoidal handle 3073 is convenient for the operator to hold.

In some embodiments, as shown in FIG. 34 , the filter mechanism 307 further includes a reinforcement rib 30739, which is connected between the connecting rod 30731 and the handle 3073, thereby enhancing the overall strength and hardness of the filter mechanism 307 and avoiding The deformation problem of the filter mechanism 307 during the repeated taking process improves the service life of the filter mechanism 307 .

In some embodiments, in order to improve the gripping effect of the operator on the handle part 30732 and avoid slippage between the hand and the handle part 30732, the outer surfaces of the first side plate 30734, the second side plate 30735 and the third side plate 30736 Formed with anti-slip texture. In some embodiments, as shown in FIG. 34 , the first side plate 30734 , the second side plate 30735 and the third side plate 30736 are provided with a plurality of air holes 30737 arranged at intervals, and the plate-like space between the air holes 30737 Structure creates a non-slip texture.

In some embodiments, as shown in FIG. 33 , the handle 30732 is located below the air inlet 3062 and is directly opposite to the air inlet 3062, and the mixed gas (for example, the mixed gas c shown in FIG. 19 ) can pass through the ventilation hole 30737 enters the air inlet 3062 and then enters the cyclone channel to perform cyclone action. Before the mixed gas enters the air inlet 3062, it collides with the first side plate 30734, the second side plate 30735 and the third side plate 30736, and the mixed gas Part of the solid particles will fall freely into the filter mechanism 307 during the collision process, so that the subsequent clean gas (for example, the clean gas e shown in FIG. 19 ) discharged from the air inlet 3062 is cleaner.

In some embodiments, as shown in FIG. 33 and FIG. 34 , the partition 30726 can be provided with an anti-backflow structure 30738, so that the sewage entering the upper space of the box body 301 from the sewage pipe 302 can at least enter the lower part through the anti-backflow structure 30738 Stored in the space, the anti-backflow structure 30738 prevents the sewage in the lower space from flowing through it and enters the upper space. In some embodiments, the anti-backflow structure 30738 can be the anti-backflow structure 230 described above (eg, FIG. 8 ).

In some embodiments, for a cleaning device with a dirt storage tank 300 (for example, the cleaning device 100 shown in FIGS. When the angle relative to the horizontal plane is 90 degrees or greater than or equal to 60 degrees, hereinafter referred to as "upright"), the sewage will be sucked into the sewage pipe 302, flow into the upper space from the sewage pipe 302, and then enter the lower space through the anti-backflow structure 30738 and Stored in the lower space. When the fuselage 1 (or the dirt storage tank 300) is greatly tilted (for example, the angle relative to the horizontal plane is less than or equal to 30 degrees, or even the angle relative to the horizontal plane is about 2 degrees, hereinafter referred to as "laying flat"), prevent The backflow structure 30738 will prevent the sewage in the lower space from flowing back through the anti-backflow structure 30738 and enter the upper space, so that the sewage will not flow to the motor (for example, the motor 33 or the motor 34) in the cleaning device 100, and the motor will not Stop, the cleaning device 100 can still perform cleaning work normally. Therefore, the cleaning device 100 with the dirt storage tank 300 can not only use the body 1 upright, but also can tilt the body 1 greatly, or even use it flat, which greatly facilitates the use of the user.

Fig. 35 is a schematic perspective view of a floor brush according to some embodiments of the present specification. In some embodiments, the floor brush 2 shown in FIGS. 1 to 7 may specifically be the floor brush 400 shown in FIG. 35 . The floor brush in the embodiment of this specification will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 35 , the ground brush 400 may include a working portion 410 and a connecting portion 420. The ground brush 400 has opposite front and rear portions in its width direction (for example, the W direction shown in FIG. 35 ), and the connecting portion 420 It is arranged at the rear of the working part 410 , and the connecting part 420 is connected with the fuselage 1 . In some embodiments, the working part 410 and the connecting part 420 can be an integrated structure, or can be independent structures. In some embodiments, the working part 410 is composed of a ground brush main body 430 and a cleaning liquid tank 440 (ie, the cleaning liquid tank 50 described above) detachably installed on the ground brush main body 430 . Wherein, the floor brush main body 430 can be in direct contact with the surface to be cleaned (for example, the ground) for cleaning the garbage on the surface to be cleaned. The main body 430 of the floor brush is provided with a suction port 434 for sucking in garbage. The cleaning liquid tank 440, as a part of the cleaning liquid supply assembly, stores cleaning liquids such as clean water, detergent or care agent. In the scenario where the surface to be cleaned needs to be sprayed wet, the cleaning liquid is pumped from the cleaning liquid tank 440 to the on the clean surface.

In some embodiments, the cleaning liquid tank 440 can be made of transparent material or non-transparent material, so that the user can judge the amount of cleaning liquid in the cleaning liquid tank 440 . In some embodiments, the cleaning liquid tank 440 may be a one-piece structure. In some embodiments, the transparent material may include but not limited to one or more of polymethyl methacrylate, polystyrene, polycarbonate, styrene acrylonitrile, ABS plastic, and the like. In some embodiments, the cleaning liquid tank 440 may also be a tank structure composed of multiple elements. For example, the cleaning solution tank 440 may include a first casing and a second casing arranged in sequence from top to bottom, and the bottom of the first casing is connected to the top of the second casing to form the cleaning solution tank 440 with a chamber inside. . In some embodiments, the connection manner of the first shell and the second shell may be one or more of glue joint, clip joint, welding and the like. For example, the first shell and the second shell can be welded by ultraviolet light curing glue (UV glue). In some implementations, the materials of the first shell and the second shell may be the same or different. For example, in order to increase the weight of the cleaning liquid tank 440 to increase the pressure of the floor brush 1 on the cleaning surface and improve the cleaning effect, in some embodiments, the first housing can be made of polymethyl methacrylate, polystyrene, poly Carbonate, styrene acrylonitrile, ABS plastic and other materials, the second housing can be made of glass, ceramics, metal (for example, stainless steel) and other materials. In some embodiments, the shape of the cleaning liquid tank 440 may be approximately a cuboid structure, a trapezoidal structure, or the like.

When the cleaning liquid tank 440 is filled with cleaning liquid, the projection of the center of gravity of the cleaning liquid tank 440 along its height direction is located in the middle area of the cleaning liquid tank 440 . It should be noted that the center of gravity of the cleaning liquid tank 440 moves up and down along the height direction of the cleaning liquid tank 440 with the amount of cleaning liquid. For example, when the cleaning liquid tank 440 is a regular structure (for example, approximately cuboid structure), when the amount of cleaning liquid in the cleaning liquid tank 440 is the maximum (that is, the cleaning liquid tank 440 is filled with cleaning liquid), the cleaning liquid tank 440 The center of gravity of is the geometric center of the cleaning solution tank 440. For another example, when the amount of cleaning liquid in the cleaning liquid tank 440 is less than the capacity of the cleaning liquid tank 440 , the center of gravity of the cleaning liquid tank 440 is located below the geometric center of the cleaning liquid tank 440 . In this way, when an outlet is opened at the bottom of the cleaning liquid tank 440 , the cleaning liquid can easily flow out from the outlet of the cleaning liquid tank 440 under the action of its own gravity. In addition, when the cleaning liquid tank 440 has an irregular structure, for example, the cleaning liquid tank 440 has a recessed or protruding area relative to its side wall, the projection of the center of gravity of the cleaning liquid tank 440 along its height direction is at the center of the cleaning liquid tank 440. 440, so that when the user extracts the cleaning liquid tank 440 filled with cleaning liquid, the center of gravity of the cleaning liquid tank 440 does not deviate excessively, so that the user can grab it.

In some embodiments, the outlet of the cleaning liquid tank 440 may be located at the central area of the bottom of the cleaning liquid tank 440 so that the cleaning liquid can flow out. In some embodiments, the outlet of the cleaning liquid tank 440 may also be located at other positions of the cleaning liquid tank 440 , for example, may be located at a side of the cleaning liquid tank 440 . In order to facilitate the setting of the pipeline (for example, the first pipeline). To reduce the length of the pipeline, the outlet of the cleaning liquid tank 440 may be located on the side of the cleaning liquid tank 440 away from the shaft (for example, the shaft 11 shown in FIG. 6 ).

In some embodiments, the cleaning liquid in the cleaning liquid tank 440 can also be sprayed out through the cleaning liquid supply assembly (for example, nozzle 460 and pump 461 shown in FIG. 440 is pumped to the nozzle 460, and the nozzle 460 is used as the output end of the cleaning liquid supply assembly to spray the cleaning liquid onto the ground to be cleaned, thereby cleaning and/or caring the ground.

In some embodiments, the cleaning solution tank 440 may include a water inlet 4401 for injecting cleaning solution or aqueous solution, the water inlet 4401 may be located at the top wall of the cleaning solution tank 440, the water inlet 4401 penetrates the top wall of the cleaning solution tank 440 and It communicates with the chamber inside the cleaning liquid tank 440 . In some embodiments, a hole plug may be provided at the water inlet 4401 , and the hole plug is matched with the inlet 4401 , for example, the two are connected through threaded connection, interference fit, plug-in connection and the like. In some embodiments, cleaning fluid tank 440 may include one or more chambers therein. For example, cleaning fluid tank 440 may include a chamber therein in which the cleaning fluid is located. For another example, the cleaning solution tank 440 may include a first chamber and a second chamber, wherein the first chamber may communicate with the second chamber, the first chamber is used to place the aqueous solution, and the second chamber is used to place the cleaning solution. The cleaning agent is injected into the first chamber with an aqueous solution to dissolve or dilute the cleaning agent, thereby forming a cleaning solution.

In some embodiments, the cleaning solution tank 440 may include a first grip 4402 for a user to hold, and the first grip 4402 is located at the top wall of the cleaning solution tank 440 . In some embodiments, the first gripping part 4402 can be a handle. In some embodiments, the first gripping portion 4402 may include a first concave portion that is concave downward relative to the top of the cleaning solution tank 440, where the first concave portion and the top wall of the cleaning solution tank 440 above form a handle-like structure , so that the user can take the cleaning solution tank 440 . In some embodiments, the cleaning liquid tank 440 may further include a second gripping portion 4403 , and the second gripping portion 11204 is located on the side wall of the cleaning liquid tank 440 facing the connecting portion 420 . For example, the second gripping portion 4403 may be a recessed area of the side wall of the cleaning solution tank 440 facing the connecting portion 420 . In some embodiments, the first gripping part 4402 and/or the second gripping part 4403 may be located in the central area of the cleaning liquid tank 440 . After the cleaning solution tank 440 is filled with water, since the bottom of the cleaning solution tank 440 needs other parts (for example, the first convex part 43141 of the pump 461 involved in the following) to form a recessed area, so that the cleaning solution tank The center of gravity of 440 is offset relatively away from the side of the recessed area, but the center of gravity of the cleaning solution tank 440 is still within the projection of the first gripping part 4402 or the second gripping part 4403, so that the user can move the cleaning solution tank 440 When reaching the vicinity of the fuselage 1, the cleaning liquid tank 440 is basically kept in balance. In addition, the cleaning solution box 440 is roughly dumbbell-shaped, and the user can grasp the cleaning solution box 440 through the first gripping part 4402 or the second gripping part 11204, for example, the first gripping part 4402 is a clasp, and the second gripping part 4402 The portion 4403 is roughly a recessed area, and the user can hold the cleaning solution tank 440 like a dumbbell.

For convenience of description, the length direction in this specification can be represented by the L direction shown in FIG. 35 , the height direction can be represented by the H direction in FIG. 35 , and the width direction can be represented by the W direction in FIG. 35 .

By installing the cleaning liquid tank 440 on the floor brush main body 430, it is convenient for the user to operate the body and clean the space under the bed. At the same time, the adoption of the above structure does not require a long cleaning liquid water pipe, resulting in a faster spraying response. In addition, such setting can also increase the overall weight of the floor brush 400, thereby increasing the force of the floor brush 400 to press down on the ground and improving the cleaning effect.

Setting the cleaning liquid tank 440 on the floor brush 400 may cause the size of the working part 410 to become larger, so that it cannot be conveniently dragged to the bottom of the bed, corners and other areas for cleaning. As shown in FIG. 35 , FIG. 36 and FIG. 37 , in order to solve the above problems, in some embodiments, the projection of the working part 410 along its height direction (direction H shown in FIG. 35 ) can be approximately rectangular, and the working The maximum dimension d1 of the portion 410 along its length direction (L direction shown in FIG. 35 ) is not more than 270 mm. Compared with other shapes, the working part 410 projected approximately in a rectangular shape has a large cleaning range and takes up little space during a single push and pull, and at the same time, the connecting part 420 and the cleaning liquid tank 440 can be conveniently arranged. In addition, by adjusting the maximum dimension d1 of the working part 410 along its length direction, the efficiency of cleaning the corners of the working part 410 can be improved. When the maximum dimension d1 of the working part 410 along its length direction is too small, its cleaning efficiency in the open area is low. Preferably, the maximum length of the working part is preferably 250mm-270mm.

The working part 410 can not only be used as an upstream part for sucking garbage, but also can cooperate with the connecting part 420 to support parts such as the fuselage, the handle) in the cleaning device, and simultaneously have the effect of installing the cleaning liquid tank 440. In order to achieve the smallest possible size of the working part 410 under the premise of satisfying the stable supporting function of the working part 410 and the function of installing the carrier. In some embodiments, it can be realized by adjusting the length or width of the working part 410 . In some embodiments, the ratio of the maximum dimension d2 along the width direction of the working part 410 to the maximum dimension d1 along the length direction of the working part 410 ranges from 0.5 to 0.7. It should be noted that the working part 410 serves as the frame structure of the ground brush 400 , and the size of the working part 410 may be approximately the size of the ground brush 400 .

In order to ensure that the cleaning liquid supply assembly can spray a sufficient area, in some embodiments, the capacity of the cleaning liquid tank 440 may be 0.35L-0.6L. Since the cleaning liquid tank 440 has a tank shell, its volume (the required space) must be greater than its capacity. In some embodiments, the ratio of the capacity of the cleaning liquid tank 440 to the volume of the cleaning liquid tank 440 is not less than 0.35. By setting in this way, when the capacity of the cleaning liquid tank 440 is preset, the cleaning liquid tank 440 can be restricted from occupying too much space, and the overall compactness of the working part 410 can be improved.

In some embodiments, the ratio of the volume of the cleaning liquid tank 440 to the volume of the working part 410 may range from 0.3 to 0.6. In this way, when the length and width of the working part 410 are determined, the height thereof can be constrained, so that the floor brush 400 can be conveniently inserted into the height-limited areas such as the bottom of the bed and the bottom of the sofa for cleaning. In some embodiments, the ratio of the maximum dimension d3 along the height direction of the working part 41 to the maximum dimension d1 along the length direction of the working part 41 can be in the range of 0.25-0.55, so as to satisfy the cleaning performance, convenience and aesthetics of the working part 410 at the same time .

In order to make full use of the installation space on the ground brush body 430 and match the basic shape of the working part 410, in some embodiments, the projection of the cleaning liquid tank 440 along its height direction is substantially rectangular, and the cleaning liquid tank 440 is substantially rectangular along its length direction. The maximum dimension d4 of the working part 410 is basically consistent with the maximum dimension d1 of the working part 410 along its length direction. It can be understood here that, along the length direction of the ground brush 400 , the distance between the two sides of the cleaning liquid tank 440 is substantially equal to the distance between the two sides of the ground brush main body 430 . In this way, the circumferential limiting function of the installation shell on the cleaning liquid tank 440 can be retained, and the upper structure of the cleaning liquid tank 440 can be expanded to be basically consistent with the maximum dimension of the working part 410 along its length direction. Simultaneously, the size of the cleaning liquid tank 440 along its length direction is designed to be as large as possible, and it is also convenient to adjust the size of the cleaning liquid tank 440 along its height direction and the size along its width direction, thereby facilitating the installation of components on the design working part 410 Location.

It should be noted that, since the cleaning solution tank 440 needs to be provided with a necessary limiting structure and/or to avoid other components (such as the connection part 420 ) during installation, the cleaning solution tank 440 in the top view may not be a regular rectangular shape. shape. The substantially rectangular shape here means that both pairs of opposite sides have substantially parallel parts; in addition, it should also be understood that the projection of the aforementioned working part 410 along the height direction is substantially rectangular.

Further, the rear end of the cleaning liquid tank 440 can at least constitute a part of the rear end of the working part 410 , that is, the cleaning liquid tank 440 is arranged as far back as possible to avoid components located at the front of the floor brush body 430 .

In some embodiments, as shown in FIG. 35 , the ground brush body 430 may include a mounting shell 431, an upper cover 432, and a rolling brush 433; the rolling brush 433 is rotatably arranged at the front of the mounting shell 431 for rolling scrubbing. On the surface to be cleaned, the upper cover 432 can be arranged on the upper part of the roller brush 433 for covering at least part of the roller brush and as an installation carrier. Meanwhile, the cleaning liquid tank 440 is disposed at the rear of the upper cover 432 . Based on the above position settings, the structure of the working part 410 can be made more compact, and its space utilization rate is high, and it is beautiful and practical.

In some embodiments, the cleaning solution tank 440 and the upper cover 432 may be integrated, and the cleaning solution tank 440 together with the upper cover 432 needs to be removed when adding cleaning solution.

In some embodiments, the cleaning solution tank 440 and the upper cover 432 can be arranged separately. It can be understood here that the cleaning solution tank 440 and the upper cover 432 are independent parts, so that the cleaning solution tank 440 can be easily separated. The cleaning solution is taken out and filled, thereby solving the problem of inconvenient operation for the user when the cleaning solution tank 440 and the upper cover 432 are integrated.

In order to further ensure that the working part 410 can smoothly extend into the bottom area of the bed, the top of the working part 410 can be an approximately flat structure, so that the top of the working part 410 should try to avoid protruding parts. That is to say, the top surface of the cleaning liquid tank 440 and the top surface of the upper cover 432 are substantially horizontal, and the above two top surfaces should be basically flat to avoid step surfaces.

In the cleaning process, considering that the two sides of the working part 410 along the length direction are easy to collide with obstacles, in order to reduce the impact caused by the collision, in some embodiments, the upper cover 432 and the cleaning liquid tank on the upper part of the working part 410 Both sides of the 440 along the length direction of the floor brush are provided with rounded corners or chamfered corners.

Referring to FIG. 35 to FIG. 42 , in some embodiments, the upper cover 432 is detachably connected to the installation shell 431 , so as to facilitate cleaning and disassembly of the roller brush 433 . Compared with the scheme of setting the cleaning liquid tank 440 and the upper cover 432 integrally, by setting the cleaning liquid tank 440 and the upper cover 432 separately, and the upper cover 432 is detachably connected to the installation shell 431, the work is further optimized. The structure of the part 410 is more in line with the usage habits of the user.

It should be noted that if the width of the upper cover 432 is too small, it will be difficult to fully realize the beneficial effects of cleaning and disassembling the roller brush. Based on this, in some embodiments, the ratio of the maximum dimension d5 of the cleaning liquid tank 440 along its width direction to the maximum dimension d2 of the working part 410 along its width direction may range from 0.5 to 0.7. By limiting the maximum dimension (eg, maximum width) of the cleaning liquid tank 440 along its width direction, the upper cover 432 provides sufficient installation space.

As shown in Fig. 35, Fig. 38 and 39, in some embodiments, the installation shell 431 may include a bottom shell 4311 and a top cover 4312, and a roll brush installation cavity for placing the roll brush 433 is formed between the bottom shell 4311 and the top cover 4312 450. The installation shell 431 of the floor brush main body 430 is configured with a suction port 434 for sucking garbage. The suction port 434 is located on the front side of the bottom case 4311 and at the rear of the roller brush 433; The ground brush channel 451 (that is, the first channel 6 shown in FIGS. 2 to 5 ). During the cleaning process, the rubbish on the surface to be cleaned is sucked away by the suction port 434 after being rubbed by the roller brush 433, and is continuously guided by the ground brush channel 451. The end of the ground brush channel 451 away from the suction port 434 can be connected with the first The two passages 202 are connected to transport the garbage to the dirt storage tank 4 (shown in FIGS. 2 to 5 ).

Since the ground brush channel 451 occupies a certain height in the roller brush installation chamber 450 , it is necessary to limit the height of the cleaning liquid tank 440 located on the upper part of the roller brush installation chamber 450 , so as to avoid the height of the working part 410 from being too large. In some embodiments, as shown in FIG. 36 and FIG. 43 , the ratio of the maximum dimension d6 of the cleaning liquid tank 440 along its height direction to the maximum dimension d3 of the working part 410 along its height direction may range from 0.4 to 0.7.

As shown in FIG. 38 to FIG. 43 , in some embodiments, a receiving groove 4313 is formed on the upper part of the top cover 4312 , and the cleaning liquid tank 440 is installed in the receiving groove 4313 . In some embodiments, the cleaning liquid tank 440 is detachably connected to the receiving tank 4313 . In order to facilitate taking and placing the cleaning solution tank 440 in the receiving tank 4313, in some embodiments, as shown in Figure 41 and Figure 42, the maximum dimension d6 of the cleaning solution tank 440 along its height direction may be larger than that of the receiving tank 4313 along its height direction The dimension d8 (or called the depth of the receiving groove 4313). Based on the structure of the receiving groove 4313, along the length direction of the ground brush, both sides of the top cover 4312 are configured with convex edges 4314, and at the same time, both sides of the cleaning liquid tank 440 are configured with grooves 4315 capable of correspondingly accommodating the convex edges 4314. Through the above settings, the cleaning liquid tank 440 can present a shape with a slightly longer upper part and a slightly shorter lower part. Wherein, the lower part of the cleaning liquid tank 440 is used for positioning and installation, and the slightly longer upper part is beneficial to expand the capacity of the cleaning liquid tank 440 .

In some embodiments, the slightly longer upper part of the cleaning solution tank 440 is the protrusion 4404 that protrudes toward both sides of the cleaning solution tank 440 relative to the groove 4315 in the length direction of the cleaning solution tank 440, wherein the protrusions The raised portion 1126 and the groove 4315 form a stepped structure, and the stepped structure matches with the convex edge 4314 . In some embodiments, the bottom of the water inlet 4401 of the cleaning liquid tank 440 is higher than the stepped structure, that is, the water inlet 4401 of the cleaning liquid tank 440 is higher than the junction of the groove 4315 and the protrusion 4404 . Further, the raised portion 4404 in the cleaning liquid tank 440 has a chamber communicating with the cleaning liquid tank 440, that is, the raised portion 4404 is a hollow structure inside. When the cleaning liquid tank 440 is filled with cleaning liquid, the cleaning liquid tank The space above the groove 4315 in the protrusion 4404 in the 440 can store cleaning liquid, thereby ensuring the capacity of the cleaning liquid tank 440 . As shown in FIG. 40 , in some embodiments, the water inlet 4401 of the cleaning solution tank 440 is higher than the stepped structure formed by the raised portion 4404 and the groove 4315, so that the inside of the raised portion 4404 can store cleaning liquid, thereby The storage space of the cleaning liquid tank 440 is increased. In some embodiments, the maximum dimension d11 of the inner space of the protrusion 4404 along its height direction may be 10-20 mm. For example, the maximum dimension d11 of the inner space of the protrusion 4404 along its height direction may be 14mm. In some embodiments, along the length direction of the floor brush 400 , the dimension d12 of the internal space of the raised portion 4404 may be 8-15 mm, for example, the dimension d12 of the inner space corresponding to the raised portion 4404 may be 11 mm.

If the size of the groove 4315 along its height direction is small, the convex edge 4314 has a poor limit to the groove 4315, and the cleaning liquid tank 440 is likely to shake. If the depth of the groove 4315 along its height direction is too large, the space expansion range of the cleaning liquid tank 440 located on the upper part of the groove 4315 is limited, resulting in little significance for space expansion in this form. In order to solve the above problems, as shown in FIG. 39 and FIG. 42 , in some embodiments, the ratio of the dimension d10 of the groove 4315 along its height direction to the maximum dimension d6 of the cleaning liquid tank 440 along its height direction may range from 0.4 to 0.7.

If the convex edge 4314 is thinner, its strength is poor, and it is difficult to effectively limit the cleaning liquid tank 440; if the convex edge 4314 is thicker, the groove 4315 needs to be enlarged, and a certain capacity of the cleaning liquid tank will be sacrificed. Therefore, as shown in FIG. 42 , along the length direction of the ground brush 400 , the dimension d7 of the convex edge 4314 is 7mm˜10mm.

In some embodiments, the cleaning liquid tank 440 can be connected to the installation shell 431 through a connection structure such as a lock structure, a buckle structure, etc. , the cleaning liquid tank 440 can be fixed with the installation shell 431 through a magnetic structure. In some embodiments, as shown in FIG. 38 , FIG. 39 and FIG. 45 , the bottom of the cleaning solution tank 440 can be fixed with a first iron body 441 , and a motor that can generate suction with the first iron body 441 is fixed in the roller brush installation cavity 450 . The first magnet 442. By setting in this way, not only can the space occupied by the connecting structure be reduced, but also the connecting structure can be hidden, so that the structure of the working part 410 is more compact and beautiful. In some embodiments, the above-mentioned magnetic attraction structure can also be realized by exchanging the positions of the first iron body 441 and the first magnet 442 , and setting two magnets for magnetic attraction.

In some embodiments, as shown in FIG. 42 and FIG. 43 , the bottom of the cleaning liquid tank 440 may also be provided with a first liquid nozzle 443 and a positioning block 444 . Wherein, the first liquid socket 443 can form a valve assembly with the first liquid socket 4319 located on the mounting shell 431, and when the two are plugged in, the cleaning liquid can flow out from the cleaning liquid tank 440. The positioning block 444 can be inserted into the insertion hole 4318 in the installation shell 431 to play a positioning role. In addition, the valve assembly can also have other structures. As shown in FIG. 40 and FIG. 41 , in some embodiments, a valve assembly 4405 may be provided at the outlet 4401 of the cleaning solution tank 440 , and at least part of the valve assembly 4405 may protrude into the inside of the cleaning solution tank 440 . In some embodiments, the valve assembly 4405 can include an assembly outlet 44051 , a rod release insert 44052 and an insert spring 44053 . In some embodiments, the component outlet 44051 may be a structure that penetrates the inside, that is, the component outlet 44051 has an internal channel. Wherein, the assembly outlet 44051 is installed to the outlet 4401 of the cleaning solution tank 440 through a threaded cap 44054 . The rod release insert 44052 is mated with the assembly outlet 44051 through a gasket (for example, an O-ring), and the rod release insert 44052 can control the opening and closing state of the internal channel of the assembly outlet 44501, that is, by changing the position of the rod release insert 44052 The position can change the opening and closing state of the internal channel of the component outlet 44051 . For illustrative purposes only, in some embodiments, the rod release insert 44052 is a cylindrical structure, and the rod release insert 44052 may at least include a first cylindrical structure and a second cylindrical structure sequentially connected from top to bottom body, wherein the radius of the first cylindrical structure is greater than the radius of the second cylindrical structure, the radius of the first cylindrical structure is approximately the same as the inner diameter of the component outlet 44051, and the radius of the second cylindrical structure is smaller than the component outlet 44051 inner diameter. Insert spring 44053 biases valve assembly 4405 inside spring housing 44056 to the closed position. Specifically, under the action of the insert spring 44053, the first cylindrical structure of the rod release insert 44052 is mated with the inside of the assembly outlet 44051. At this time, the valve assembly 4405 is closed, and the cleaning liquid in the cleaning liquid tank 112 cannot It flows out from the cleaning liquid tank 440 to the outside world. When the valve assembly 1130 is connected with the cleaning liquid supply assembly, the rod release insert 44052 deforms the insert spring 1138 under the action of the pipeline interface pressure, and the first cylindrical structure of the rod release insert 44052 is relative to the assembly outlet 44051. The inner channel moves. At this time, the second cylindrical structure is located at the inner channel of the component outlet 44051, there is a gap between the second cylindrical structure and the side wall corresponding to the inner channel of the component outlet 1132, and the valve component 4405 is in an open state. to release fluid to the fluid delivery channels (eg, first, second, and third conduits). In some embodiments, the rod release insert 44052 can be a reduced diameter rod structure, that is, the radius of the rod release insert 44052 increases from top to bottom. Regarding the principle that the rod release insert 44052 can be a different-diameter rod structure to cooperate with the assembly outlet 44051, reference can be made to the above content. In some embodiments, the valve assembly 4405 may also include a screen insert (not shown) to prevent particulate matter from entering the cleaning fluid supply assembly. In some embodiments, a screen insert may be disposed between the cleaning fluid tank outlet 4401 and the valve assembly 4405 . In some embodiments, the screen insert may also be disposed on the side of the outlet 4401 of the cleaning fluid tank 440 away from the valve assembly 4405 .

In order to ensure that the cleaning liquid from the nozzle 460 onto the floor to be cleaned can wet the floor, in some embodiments, the area of the water outlet of the valve assembly can be greater than 3 mm ² . Preferably, the water outlet area of the valve assembly is larger than 4mm ² . Further preferably, the water outlet area of the valve assembly is greater than 5mm ² . More preferably, the water outlet area of the valve assembly is larger than 6mm ² . In some embodiments, the inner diameter of the rod release insert 44052 or the assembly outlet 44051 can be adjusted to ensure the water output of the valve assembly.

45 and 46, in some embodiments, the rolling brush 433 may include a brush barrel 4335 and bristles 4336 fixed on the outer periphery of the brush barrel 4335, and a partition 4337 perpendicular to its length direction is fixed inside the brush barrel 4335. Wherein, a plurality of connecting grooves 43371 are uniformly arranged on the partition plate 4337, and a plurality of connecting columns 43372 that can be correspondingly inserted into the connecting grooves 43371 are arranged on the output shaft of the gearbox 4332. When the motor 4331 is started, the connecting column 43372 can apply force to the connecting groove 43371 to drive the roller brush to rotate.

In some embodiments, the connecting columns 43372 extend outward along the radial direction of the output shaft of the gearbox, and the greater the number, the better the transmission stability of the rolling brushes 433 and the gearbox 4332 . As a preference in this embodiment, the number of connecting posts 43372 and connecting grooves 43371 can be set to three. It should be noted that the number of connecting posts 43372 and connecting grooves 43371 is not limited to the above three, but can also be one, two or more than three, and the specific number can be adjusted adaptively according to the actual situation.

After the cleaning is over, sometimes the rolling brush 433 needs to be disassembled separately for cleaning. Since the motor 4331 and the gearbox 4332 are arranged inside the brush tube 4335, the rolling brush 433 can only be pulled out relative to the bottom shell 4311 along its length direction. However, when the roller brush 433 is installed again, there will be a problem that the connecting post 43372 and the connecting groove 43371 are not easy to align, resulting in poor user experience. In order to solve this problem, in some embodiments, the connecting column 43372 can be substantially cylindrical, and at the same time, the outer edge of the connecting groove 43371 is formed with rounded corners or chamfers 43373; based on the above structure, during the process of inserting the roller brush 433 The substantially cylindrical connecting column 43372 can be smoothly inserted into the connecting groove 43371 along the fillet or chamfer.

In some embodiments, the pull block 4715 is all set in the recessed part 4714, so that the pull block 4715 will not protrude from the plane of the cover plate part 471 facing away from the bottom shell 4311, so as not to interfere with the working part 410 along its length direction. It has an impact on the maximum size of the car, and it is not easy to bump into obstacles.

In some embodiments, the pull block 4715 and the support sleeve 472 can be connected together by bolts, screws, etc., which is designed for easy disassembly and facilitates subsequent parts cleaning and maintenance. In some embodiments, a limiting sleeve 4716 may be disposed on the cover member 471 , and the supporting sleeve 472 is inserted into the limiting sleeve 4716 with interference. Based on this structure, the installation stability of the support sleeve 472 can be improved, and the support sleeve 472 can be prevented from shaking relative to the cover plate 471 , thereby ensuring the rotational dynamic balance performance of the roller brush 433 .

Since the rotating sleeve 475 can rotate relative to the cover member 471 , there needs to be a gap between them, and filaments such as hair and wadding will inevitably enter the rotating sleeve 475 through the gap during the cleaning process. In order to prevent filaments from being entangled on rotating parts such as the first bearing 473 and the connecting rod 474, in some embodiments, a flared portion 4721 is provided on the side of the supporting sleeve 472 facing the rotating sleeve 475, and the flared portion 4721 surrounds the Rotating parts such as the first bearing 473 and the connecting rod 474 make the passage between the rotating part and the external environment become tortuous, thereby preventing the above-mentioned filaments from contacting these rotating parts, and the flaring part 4721 will not hinder these rotating parts rotation. In a specific embodiment, along the height direction m of the roller brush 433 (shown in FIG. 38), the minimum distance between the flaring portion 4721 and the rotating sleeve 475 is not greater than 1.5mm. In this case, such a small distance further makes it almost impossible for the filament to reach the above-mentioned rotating member. Wherein, the supporting sleeve 472 and the rotating sleeve 475 are basically arranged coaxially, so the above-mentioned two minimum distances are respectively the minimum distance between the outer edge of the flared portion 4721 and the inner wall of the rotating sleeve 475, and the distance between the right end of the flared portion 4721 and the rotating sleeve 475. Minimum spacing between another inner wall.
