The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

It should also be understood that the terminology used in the specification of this application is for the purpose of describing particular embodiments only and is not intended to limit the application. As used in this specification and the appended claims, the singular forms "a", "an" and "the" are intended to include plural referents unless the context clearly dictates otherwise.

It should be further understood that the term "and/or" used in the description of the present application and the appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations .

In some embodiments of the present application, the following embodiments and features in the embodiments may be combined with each other under the condition of no conflict.

In some embodiments of the present application, referring to FIGS. 1-3 , the cleaning device 10 has a main body 100 and a chassis 200, the main body 100 is rotatably arranged on the chassis 200, the main body 100 has a handle 110 for the user to hold, and the cleaning device 10 is working During the process, the user holds the handle 110 and uses the main body 100 to push the chassis 200 to control the cleaning device 10 to move forward, backward or turn, so as to use the cleaning parts 210 on the chassis 200 to clean the surface to be cleaned. Generally, the cleaning device 10 has a clean water tank and a dirty water tank. The clean water tank supplies water to the cleaning element 210 or the ground, and the water can wet the surface to be cleaned so that the cleaning element 210 can better clean the dirt on the ground. During the cleaning process, the cleaning equipment 10 utilizes the first suction device 400 (such as a negative pressure source such as a fan) to recycle the generated dirt into the sewage tank. The first suction device 400 needs to communicate with the sewage tank. However, when the sewage tank Or when the part of the waste water tank is located on the main body 100 of the cleaning device, the cleaning device is in the process of working, because the main body 100 will shake, tilt (compared with the horizontal plane) or horizontal (compared with the horizontal plane), the sewage The water or water vapor in the tank is easy to enter the first suction device 400, and then cause the first suction device 400 to be flooded or even damaged, especially the smaller the angle between the main body 100 and the horizontal plane, the lower the first suction device 400. The greater the probability of water. Therefore, in the related art, in order to ensure that the first suction device 400 will not enter the water, the angle at which the main body 100 can rotate relative to the chassis 200 is usually limited. This solution makes the cleaning device 10 unable to clean the bottom of the bed, the bottom of the sofa, etc. low area. Based on this, the embodiment of this application proposes the following solutions:

As shown in Figures 1-3, the first aspect of the embodiment of the present application provides a cleaning device 10, including a chassis 200, a main body 100, a first warehouse 310, a second warehouse 320, a first suction device 400 and a second suction device Suction device 500, wherein the main body 100 is rotatably connected to the chassis 200.

It should be noted that the main body 100 is rotatably connected to the chassis 200, so that the main body 100 can be switched between an upright state (as shown in FIG. 1 ), an inclined state (as shown in FIG. 2 ), and a lying state (as shown in FIG. 3 ). Wherein, when the lengthwise direction of the main body 100 (as shown in the dotted line direction in Figure 1) is approximately perpendicular to the chassis 200 (or the horizontal plane), the cleaning device 10 is in an upright state, which is usually the placement posture of the cleaning device 10; the main body 100 When the length direction of the main body 100 and the chassis 200 (or horizontal plane) are in an acute angle state, the cleaning device 10 is in an inclined state, which is usually the normal working posture when the cleaning device 10 works; and the length direction of the main body 100 and the chassis 200 ( Or the horizontal plane) is roughly parallel, the cleaning device 10 is in a lying state, which is usually the limit working posture when the cleaning device 10 works, and is used to clean low areas, such as the bottom of the bed and the bottom of the sofa.

In some embodiments, as shown in FIG. 4, the first warehouse 310 can be arranged on the main body 100, and the second warehouse 320 can be arranged on the chassis 200; in some other embodiments, as shown in FIGS. 5 and 6, the first warehouse 310 and the second compartment 320 are both disposed on the main body 100 . Correspondingly, the first suction device 400 and the second suction device 500 can be arranged on the main body 100 at the same time, or the first suction device 400 is arranged on the main body 100 and the second suction device 500 is arranged on the chassis 200 , even the first suction device 400 and the second suction device 500 may also be disposed outside the cleaning device 10, which is not limited by the present application.

Regarding how to form the first bin 310 and the second bin 320, as shown in FIGS. There is the above-mentioned first warehouse 310, and the second housing 320a is formed with the above-mentioned second warehouse 320, and the first housing 310a can be fixed on the outside of the second housing 320a by assembly (as shown in Figure 5) or, the first housing 310a is disposed on the main body 100, and the second housing 320a is disposed on the chassis 200 (as shown in FIG. 4 ). At this time, the first housing 310a and the second housing 320 are independent of each other, so they can be assembled and fixed on the main body 100 as shown in FIG. together; as shown in FIG. 4 , they can be arranged separately and placed on the main body 100 and the chassis 200 respectively. Alternatively, as shown in FIG. 6 , the cleaning device 10 includes a first housing 310a and a second housing 320a, at least part of the first housing 310a is nested in the second housing 320a. Exemplarily, as shown in FIGS. 7-10 , a part of the inner wall of the second housing 320a and a part of the outer wall of the first housing 310a form the second bin 320; the first housing 310a forms the first bin 310 (as shown in FIG. 7 and 8), or, part of the inner wall of the first housing 310a and part of the inner wall of the second housing 320 jointly form the first chamber 310 (as shown in Figures 9 and 10 ).

In addition, it should be noted that the external liquid described in the embodiments of the present application may be dirt (dirt includes solid-liquid mixture and sewage) or clean water. The first suction device 400 in the embodiment of the present application mainly provides driving power for the external liquid to enter the first chamber 310 . Wherein, the outside refers to the part other than the first bin 310 and the second bin 320 .

When the sucked liquid is sewage or a solid-liquid mixture, the water tank 300 is a sewage tank, and the first suction device 400 can recycle the dirt generated during the cleaning process of the cleaning device 10 to the sewage tank, so as to facilitate subsequent treatment by users.

When the sucked liquid is clean water, at this time, the first suction device 400 can suck the external clean water into the first chamber 310 . When the first bin 310 and the second bin 320 form a sewage tank, clean water can clean the first bin 310 and/or the second bin 320 to maintain the water tank.

The following mainly takes the external liquid as a solid-liquid mixture or sewage as an example for illustration.

As shown in Figures 4-6, the first suction device 400 can be used to suck the external dirt (including solid and liquid garbage, sewage, etc.) Recycling of dirt, oil or impurities. Wherein, the cleaning device 10 can also suck the mixture of external solid waste and sewage into the first bin 310 , which is not limited in this application. The chassis 200 of the cleaning device 10 is provided with a cleaning piece 210 for cleaning the surface to be cleaned. The cleaning piece 210 can be a cleaning component such as a rolling brush. One end of the main body 100 is provided with a handle 110 for being held by the user. The handle 110 drives the main body 100 to push the chassis 200 forward, backward or turn. The first chamber 310 is arranged on the main body 100, the second chamber 320 communicates with the first chamber 310, and the first suction device 400 communicates with the first chamber 310, so that the first suction device 400 can drive the external liquid into the first chamber. The power of Yicang 310. Exemplarily, the first suction device 400 may be a large-flow negative pressure source capable of providing negative pressure, such as a fan, so as to suck external liquid into the first chamber 310 . The second chamber 320 communicates with the first chamber 310, and the second chamber 320 can be understood as indirect communication with the first suction device 400 through the first chamber 310. When the communication channel between the first chamber 310 and the second chamber 320 is blocked , the first suction device 400 is only in communication with the first chamber 310 .

As shown in Figures 4-10, there is a partition between the first warehouse 310 and the second warehouse 320 (the partition can be the bottom wall and/or side wall of the first warehouse 310), so that the first warehouse 310 and the second warehouse The second warehouse 320 is relatively independent, and then prevents the liquid in the second warehouse 320 from flowing back to the first warehouse 310 through the separator; the communication between the first warehouse 310 and the second warehouse 320 means that there is a passage for liquid communication between the two, wherein , “channel” includes but not limited to holes, pipes, gaps, etc., and the channel is used to allow the liquid in the first chamber 310 to enter the second chamber 320 .

The second suction device 500 communicates with the second chamber 320, and the second suction device 500 can provide the power to drive the liquid in the first chamber 310 into the second chamber 320, thereby further hindering the liquid in the second chamber 320 from the supply. The channel through which the liquid flows returns to the first chamber 310 .

In the embodiment of the present application, by adding the second suction device 500 to drive the liquid in the first chamber 310 to the second chamber 320, the amount of liquid in the first chamber 310 can be reduced or the liquid in the first chamber 310 can be removed, thereby reducing the amount of liquid in the first chamber 310. A risk of liquid ingress into the suction device 400 . It should be noted that the first suction device 400 is used to drive the external liquid to the first chamber 310, its suction path is longer, and the required suction flow rate is larger; and the second suction device 500 is used to The liquid in the first chamber 310 is driven to the second chamber 320, and the required suction flow can be slightly smaller; when the second suction device 500 is a gas suction device, the second suction device 500 also has a certain progress. liquid risk. However, it can be understood that when faced with the same amount of liquid to be sucked, the greater the suction flow rate, the greater the risk of liquid ingress faced by the suction device. And because the suction flow required to drive the liquid in the first chamber 310 to the second chamber 320 can be smaller, therefore, the second suction device 500 with a smaller suction flow can be selected for use, and then the liquid can also enter the second chamber. The risk of the suction device 500 is low. Since the flow required to drive the liquid in the first chamber 310 to the second chamber 320 can be small, therefore, the wind resistance of the suction channel communicating with the second suction device 500 can be further increased, such as adding some obstacles to water and/or Or water vapor enters the blocking structure of the second suction device 500 to further reduce the risk of liquid entering the second suction device 500 . How to design the blocking structure to reduce the risk of liquid entering the second suction device 500 and the specific form of the blocking structure will be described in detail in subsequent embodiments.

In addition, the risk of liquid entering the first suction device 400 can also be reduced by adding a blocking structure, because it is necessary to ensure that the first suction device 400 can always provide a large suction flow to maintain the suction of external liquid into the first chamber In the state of 310, the design of the blocking structure can be slightly simplified, so as to appropriately reduce the wind resistance and reduce the risk of water entering the first suction device 400, and at the same time, try not to affect the large suction flow provided by the first suction device 400 all the time.

In some embodiments, the second suction device 500 includes a gas suction device, the first chamber 310 and the second chamber 320 are communicated through the liquid leakage structure 312, and the horizontal direction of the suction port of the gas suction device 500 The cross-sectional area is similar to that of the liquid leakage structure. Similar means that the difference in area between the two is small. Exemplarily, such as less than 20 square millimeters. The cross-sectional areas of the two are set to be similar, so that the "suction" force of the second suction device 500 can be close to 1:1 to act on the leakage structure 312, which improves the passage of the liquid in the first chamber 310 through the leakage. The flow of the structure 312 into the second bin 320.

In the embodiment of the present application, since the first suction device 400 is directly connected to the first bin 310, and the first bin 310 has liquid recovered from the outside, the cleaning device 10 is working, especially in the first bin 310. When the liquid is filled or the main body 100 is tilted or lying down, the liquid in the first chamber 310 can easily enter the first suction device 400 directly from the first chamber 310. By setting the second suction device 500, the second suction device 500 communicates with the second chamber 320, and the second suction device 500 provides power to drive the liquid in the first chamber 310 into the second chamber 320, so that the liquid in the first chamber 310 is always less , so as to prevent the liquid in the first chamber 310 from entering the first suction device 400 when the main body 100 shakes, tilts, or lies down, thereby reducing the liquid inflow into the first suction device 400 and causing secondary pollution , or even risk of damage. Moreover, the second suction device 500 can effectively prevent the liquid in the second chamber 320 from flowing back into the first chamber 310 , causing the potential failure of the first suction device 400 .

It should be noted that the first suction device 400 and the second suction device 500 are independent suction sources, and the suction power of the two can be controlled independently. Exemplarily, when the first suction device 400 provides driving power to make the solid-liquid mixture, sewage or clean water enter the first chamber 310, the suction power may be adjusted due to environmental factors, while the second suction device 500 may be in any case Maintaining higher power both down will ensure that liquid is drawn from the first chamber 310 into the second chamber 320 .

In some embodiments, as shown in FIG. 1 , the cleaning device 10 includes a water tank 300 in which a first chamber 310 and a second chamber 320 are formed. If what is collected is dirt, the water tank 300 is a sewage tank. When the cleaning device 10 is in an upright state, the first bin 310 is located above the second bin 320 . Wherein, the water tank 300 is detachably installed on the main body 100, and the first suction device 400 and the second suction device 500 are arranged on the main body 100, so that the first suction device 400 can suck the external liquid to the sewage tank 300 In the first chamber 310 , the second suction device 500 can suck the liquid in the first chamber 310 into the second chamber 320 .

In some embodiments, as shown in FIG. 7 , the cleaning device 10 may further include a content detection component 360 and a first detection component 361 , the control device 600 is connected to the content detection component 360 and the first detection component 361 , the content detection component 360 The first detection component 361 is arranged in the first bin 310, and is used to detect the content information of the first bin 310, so that the control device 600 can adjust the first suction device 400 according to the content information detected by the first detection component 361. And/or the operating parameters of the second suction device 500 . Content information may include solid waste capacity information, liquid level information, water availability information, etc.

For example, a filter screen 352 may be provided in the first bin 310 to form a solid-liquid separation bin, and the content information at this time may indicate the capacity of solid waste.

Exemplarily, the first detection component 361 in the first warehouse 310 is arranged above the first warehouse 310;

Exemplarily, the first detection component 361 in the first compartment 310 is arranged on the rear side above the first compartment 310. Such arrangement can make the cleaning device lie down, and if there is liquid that triggers the first detection component 361, it means this At this time, there is a risk of liquid entering the first suction device 400 .

Furthermore, a prompting device (not shown) may also be included, and the prompting device is electrically connected to the first detection component 361, so that when the amount of dirt in the first bin 310 reaches a preset value or is triggered, the prompting device can notify The user replaces or cleans the first chamber 310 and/or the second chamber 320, so as to reduce the possibility that the liquid in the first chamber 310 and the second chamber 320 may flow back and cause potential safety hazards.

Exemplarily, the control device 600 is connected with the content detection component 360 and the first detection component 361 and the first suction device 400 and/or the second suction device 500 . When the amount of dirt in the first chamber 310 reaches a preset value or is triggered, the control device 600 can adjust the operating parameters of the first suction device 400 so that the suction force of the first suction device 400 is reduced or turned off, reducing the second The possibility of the liquid in the first chamber 310 entering the first suction device 400 .

At the same time, when the amount of dirt in the first bin 310 is relatively large (for example, there are more solid waste in the first bin 310), the liquid in the first bin 310 will not easily enter the second bin 320 to a certain extent. Therefore, in this scenario, the operating parameters of the second suction device 500 can be adjusted through the control device 600 to increase the suction force of the second suction device 500 so that the second suction device 500 can provide greater suction.

For example, in addition, when the amount of dirt in the second chamber 320 reaches a preset amount, the control device 600 can adjust the operating parameters of the second suction device 500 so that the suction force of the second suction device 500 is reduced or turned off. , so as to reduce the possibility of the liquid in the

second chamber

Exemplarily, the operating parameters of the first suction device 400 and the second suction device 500 include at least one of the following: operating power, operating time, operating voltage, and operating duty cycle current, so that the control device 600 can control the The working time and suction force of the first suction device 400 and the second suction device 500, etc., enable the external liquid to enter the first chamber 310, and the liquid in the first chamber 310 to enter the second chamber 320, and under control Under the control of the device 600, the first suction device 400 and the second suction device 500 can be flexibly adjusted according to the current state of the cleaning device 10, or the amount of dirt in the first bin 310 and/or the second bin 320. Operating parameters. In particular, when the amount of liquid contamination is large, the suction device can be turned off in time or the suction force of the suction device can be reduced (the greater the suction force, the greater the operating power required, and the greater the operating power, the greater the suction device will be). The greater the risk of liquid), and then protect the first suction device 400 and the second suction device 500 in time.

On the other hand, since the operating parameters of the second suction device 500 can be flexibly adjusted according to the amount of dirt in the first bin 310, when the amount of dirt in the first bin 310 is small, the second suction The operating power of the suction device 500 can be small, and when the amount of dirt in the first bin 310 is large, the operating power of the second suction device 500 should be increased. By matching the amount of dirt in the first chamber 310 with the operating parameters of the second suction device 500, the dynamic adjustment of the operating parameters of the second suction device 500 can be realized, thereby avoiding that the second suction device 500 always uses a large power The running noise is always high due to the operation, and reducing the impact of the working noise on the user experience can effectively improve the user experience.

It should be noted that, in order to clearly indicate the orientation, the embodiment of the present application defines the front side, the rear side, the left side, and the right side of the cleaning device 10; as shown in FIG. The forward side in the state; the rear side is the side opposite to the front side, that is, the side where the cleaning device 10 is in a non-turning state and deviates from the forward direction; the left side is the left hand side when the user stands towards the front side; The right side is the user's right hand side when standing facing the front side. For the main body 100, the front side refers to the side where the main body 100 swings forward, and the rear side refers to the side where the main body 100 swings backward. The swing angle of the main body 100 will change. When being in an upright state (as shown in Figure 1), the front side is the side of the advancing direction of the cleaning device 10 in a non-turning state, and when the main body 100 is in a lying state (as shown in Figure 3), the front side is the main body at this time. The upper side and the rear side of 100 are the lower side of the main body 100 at this time.

In some embodiments, referring to FIGS. 4-10 , the first chamber 310 communicates with the second chamber 320 through a liquid leakage structure 312 , so that the liquid in the first chamber 310 can enter the second chamber 320 . Wherein, the liquid leakage structure 312 may be a water leakage hole, a water leakage channel or a water leakage gap disposed between the first chamber 310 and the second chamber 320, which is not limited in this application. It should be noted that the leakage area formed by the leakage structure 312 can be as small as possible and concentrated; for example, the ratio of the area of the leakage structure 312 to the cross-sectional area of the water tank is less than 1/4, or less than 1 square centimeter. In order to make the rest of the bottom wall of the first casing 310a isolate the first chamber 310 and the second chamber 320, and the suction force of the second suction device 500 is concentrated on the smaller liquid leakage structure 312, so that the second chamber can be The liquid in the first chamber 310 is quickly sucked into the second chamber 320, so that the risk of the liquid flowing back from the second chamber 320 to the first chamber 310 or the surge liquid returning to the first chamber 310 when the cleaning device 10 shakes can be reduced. Most of the liquid remains in the second chamber 320 , reducing the amount of liquid retained in the first chamber 310 , thereby reducing the risk of liquid entering the first suction device 400 .

It should be noted that when the first chamber 310 is located above the second chamber 320, the force of the liquid in the first chamber 310 entering the second chamber 320 may include the gravity of the liquid and the force provided by the second suction device 500. suction power.

In some embodiments, the liquid leakage structure 312 may be disposed on the rear side of the first chamber 310 . In this way, when the main body 100 is tilted backward or lying down, the liquid leakage structure 312 located on the rear side of the first compartment 310 can be just at the lowest point of the first compartment 310, so that it is more convenient to use the second compartment or when lying down. The liquid in the first tank 310 flows into the second tank 320 .

In some embodiments, the liquid leakage structure 312 may be disposed at a lower portion of the first chamber 310 . Wherein, the lower part of the first warehouse 310 refers to the side wall 310c of the first warehouse 310 that is closer to the side or the bottom wall of the chassis 200, and the liquid leakage structure 312 is arranged at the lower part so that when the main body 100 is inclined or stands upright, the liquid leakage structure 312 Located at the bottom of the first chamber 310 , all the liquid in the first chamber 310 can flow into the second chamber 320 through the liquid leakage structure 312 .

In some embodiments, the liquid leakage structure 312 is arranged at the lower rear side of the first compartment 310. At this time, no matter whether the main body 100 is tilted, upright or lying down, it can ensure that the liquid leakage structure 312 is located in the first compartment 310 in the current state. bottom, so that all the liquid in the first chamber 310 can flow into the second chamber 320 through the liquid leakage structure 312 .

In an optional embodiment, referring to FIG. 12 , the largest dimension of the leaking structure 312 in the front-back direction is smaller than the smallest dimension in the left-right direction, which can be closer to the rear side, while ensuring the circulation efficiency of the leaking structure 312 . For example, the liquid leakage structure 312 may be flat.

In an optional embodiment, the number of liquid leakage structures 312 is one or several.

In the embodiment of the present application, the choice of the second suction device 500 can be a gas suction device such as a vacuum pump, a fan, or a liquid suction device such as a water pump or a peristaltic pump. Of course, the application is not limited to this, as long as It only needs to provide power to drive the liquid in the first chamber 310 to the second chamber 320 . In the following, the second suction device 500 is taken as an example of a gas suction device for illustration.

In some embodiments, the second suction device 500 includes a gas suction device 500, wherein the gas suction device 500 communicates with the second chamber 320, and is used to suck the gas in the second chamber 320 so that the second chamber Negative pressure is formed in 320 . In this way, in addition to the liquid in the first chamber 310 flowing into the second chamber 320 under the action of gravity, the negative pressure generated by the gas suction device 500 can also provide a certain force to drive the liquid from the first chamber 310 to the second chamber 320 Auxiliary force. The gas suction device 500 may be a device capable of sucking gas, such as a vacuum pump, an air pump, or a fan.

4-6, the first suction device 400 communicates with the first chamber 310 through the first suction passage 311, and the second suction device 500 communicates with the second chamber 320 through the second suction passage 321, so that the first The first chamber 310 can generate a negative pressure under the action of the first suction device 400, so that the external liquid can enter the first chamber 310, and then the second chamber 320, under the action of the second suction device 500, pushes the first chamber 310 The liquid in is pumped into the second chamber 320. Exemplarily, as shown in FIGS. 4 and 5 , the second suction channel 321 is a suction interface; or, as shown in FIG. 6 , the second suction channel 321 is an air channel.

It can be understood that when the first suction device 400 and the gas suction device 500 are in working condition, the negative pressure of the first chamber 310 at the connection point between the first chamber 310 and the second chamber 320 can be smaller than the negative pressure of the second chamber 320, So that the liquid in the first chamber 310 can flow smoothly into the second chamber 320; at the same time, due to the existence of negative pressure difference, the dirt in the first chamber 310 can enter the second chamber 320 well, and due to the liquid With fluidity, the liquid in the second chamber 320 will not flow back into the first chamber 310 when the cleaning device 10 is tilted, lying down, or shaken, which can effectively protect the first suction device 400 .

In some embodiments, further, a filter element can be set in the first bin 310 to filter solid waste in the dirt and stay in the first bin 310, while the liquid in the dirt is in the negative of the gas suction device. Enter into the second chamber 320 under the action of pressure and gravity. How to design the filter element in the first chamber 310 and the specific form of the filter element will be described in detail in the subsequent embodiments.

In the embodiment of the present application, compared with related technologies, the cleaning equipment 10 is additionally provided with a second suction device 500. When the second suction device 500 is a gas suction device 500, it is similar to the first suction device 400. The gas suction device 500 is also faced with the problem that water may enter and cause damage. Therefore, in order to further reduce the risk of liquid entering the gas suction device 500 (second suction device 500), the embodiment of the present application proposes the following solutions:

In some embodiments, referring to FIGS. 4-10 , the second suction channel 321 includes an air inlet 321b and an air outlet 321a, wherein the air inlet 321b communicates with the second chamber 320, and the air outlet 321a communicates with the gas suction device 500 (the second suction device 500 ) is connected, and the shape of the second suction channel 321 is not limited here.

Exemplarily, as shown in Fig. 4-10, the air inlet 321b of the second suction channel 321 may be located at the front side of the second chamber 320, so that when the cleaning device 10 is lying down, the air intake The port 321b can be as far away from the liquid level in the second chamber 320 as possible to reduce the probability of the liquid in the second chamber 320 being sucked into the air inlet 321b (as shown on the left side of FIG. 13 ). At the same time, since the air inlet 321b is farther away from the liquid level of the second chamber 320 when the cleaning device 10 is lying down, the volume of the second chamber 320 that can be used is larger; When the air port 321b is arranged at the front side of the second storehouse 320, the height of the liquid entering the second storehouse 320 can approach the front side of the second storehouse 320, and if the air inlet 321b is arranged at the middle part of the second storehouse 320, for Reduce the probability of liquid entering the first suction device 400 from the air inlet 321b, therefore, the height of the liquid entering the second chamber 320 can only be controlled to be lower than the middle, and the acceptable liquid height of the former is higher, thus causing the second The liquid storage volume of the chamber 320 is not as good as the air inlet 321b provided on the front side of the second chamber 320 . Therefore, disposing the air inlet 321 b at the front side of the second chamber 320 can increase the effective volume of the second chamber 320 .

In some embodiments, as shown in Fig. 4-10, the air inlet 321b of the second suction channel 321 is located above the second chamber 320, where the above refers to the overall upper part of the second chamber, so that the air inlet can 321b can be kept away from the liquid surface of the second chamber 320 to reduce the probability that the liquid in the second chamber 320 is sucked into the second suction channel 321 .

In some embodiments, as shown in FIGS. 12 and 13 , the maximum size of the air inlet 321b in the front-to-back direction of the main body 100 is smaller than the smallest size in the left-right direction of the main body 100; flat shape;. If the position of the air inlet 321b is fixed, the shape of the air inlet 321b is set in such a way that the lowest point of the opening of the air inlet 321b can be as high as possible in the lying down state. In this way, at the same liquid level, the air inlet 321b The bottom of the second chamber 320 can be further away from the liquid surface in the second chamber 320 to reduce the probability of the liquid in the second chamber 320 entering the second suction channel 321 . At the same time, since the air inlet 321b is farther away from the liquid level of the second chamber 320 when the cleaning device 10 is lying down, the volume of the second chamber 320 that can be used is larger. For example, as shown in Figure 13, when the cleaning device 10 is lying down and the air inlet 321b is flat, the height of the liquid entering the second chamber 320 can be closer to the front side of the second chamber 320, and if the The air port 321b is arranged in the second storehouse 320 instead of being flat but with an increased thickness in the front and rear directions, that is, when lying down, the opening of the air inlet 321b is in the height direction, which is equivalent to lowering the opening position. The probability of liquid entering the second suction device 500 from the air inlet 321b, therefore, can only control the height of the liquid entering the second chamber 320 can only be lower than the opening position, and the corresponding effective volume of the second chamber 320 will be reduced Therefore, setting the air inlet 321b in a flat shape can also increase the effective volume of the second chamber 320 .

It should be noted that the second suction channel 321 may also be flat as a whole.

In addition, the air inlet 321b and/or the second suction channel 321 are also located on the front side and/or above the second chamber 320, which can further reduce the probability of liquid entering the air inlet 321b321, and increase the pressure of the second chamber 320. Effective volume.

In an optional embodiment, as shown in FIG. 14 , the cross-sectional area of the second suction channel 321 may gradually decrease from the air inlet 321b toward the air outlet 321a, so that the air inlet 321b Set it as large or wide as possible in a limited space, which can reduce the probability that the air inlet 321b is completely blocked by the liquid, so even if the air inlet 321b is partially blocked by the liquid, because the fluidity of the gas is higher than that of the liquid The fluidity is large, and the gas suction device can still perform gas suction through the part of the air inlet 321b that is not blocked by the liquid during suction. Therefore, the second suction device 500 can still continue to work if it is set in this way, thereby reducing The possibility of failure of the second suction device 500 due to partial water ingress into the air inlet 321b. In addition, due to the suction direction of the second suction channel 321, the cross-sectional area of the entire second suction channel 321 gradually decreases, even if liquid enters the second suction channel 321 through the air inlet 321b, due to The cross-sectional area of the second suction channel 321 is gradually reduced, and the liquid that is sloshed into the second suction channel 321 easily hits the inner wall of the second suction channel 321, thereby being absorbed by the inner wall of the second suction channel 321. It is difficult to directly enter the gas suction device from the gas outlet 321a.

In an optional embodiment, as shown in FIG. 15 , the second suction channel 321 includes at least one guide wall 321h, and the guide wall 321h is used to guide the airflow in the second suction channel 321 from the air inlet along a curved path. 321b flows to the air outlet 321a. Wherein, the guide wall 321h is used to form a curved path in the second suction channel 321, even if water vapor enters the second suction channel 321 through the air inlet 321b, the water vapor needs to traverse the curved path in the second suction channel 321 to It is possible to reach the air outlet 321a; that is to say, the path for water vapor to reach the air outlet 321a through the air inlet 321b becomes longer, which undoubtedly increases the difficulty for water vapor to finally reach the air outlet 321a and enter the second suction device 500; When the air passes through the guide wall 321h, it can also play a certain role of water and air separation and water and air shielding, preventing water and air from being directly drawn in along the second suction channel 321 .

In some other embodiments, the guide wall 321h may be formed by bending the side wall of the second suction channel 321; or, the second suction channel 321 includes a curved side wall, and the curved side wall forms the guide wall 321h.

In some embodiments, referring to FIGS. 14-17 , the second suction channel 321 is provided with a plurality of partitions 321c alternately arranged at intervals along the suction direction, and the length direction of the partitions 321c may extend approximately along the left-right direction of the main body 100; wherein The partition 321c forms the above-mentioned guide wall 321h, and the partition 321c is used to prevent the liquid in the second chamber 320 from flowing into the air outlet 321a from the second suction channel 321, and reduce the liquid in the second chamber 320 from entering the gas suction. Possibilities in device 500.

In some embodiments, referring to FIGS. 14-16 , a diversion port 321d is provided on the partition 321c, or a diversion port 321d is provided between the partition 321c and the side wall of the second suction channel 321, and at least two diversion ports 321d are provided. The outlets 321d are distributed in a staggered manner, and the guide outlets 321d and the partitions 321c are used to guide the air flow along the curved path, so as to prevent the liquid in the second chamber 320 from entering the gas suction device 500 .

Exemplarily, an opening may be provided on the partition 321c, and the opening forms the above-mentioned diversion port 321d; or one end of the partition 321c is connected to the inner wall of the second suction channel 321, and the other end and the inner wall leave gaps, and the gaps are staggered. The gap forms the above-mentioned guide port 321d.

In an optional embodiment, please refer to the accompanying drawing 15, the diversion port 321d formed by one of the two adjacent partitions 321c is located at the left end of the partition 321c, and the other of the two adjacent partitions 321c One formed diversion opening 321d is located at the right end of the partition 321c, so that the two diversion openings 321d can be dislocated. As a result, the air flow path can be made as long as possible, thereby maximizing the water vapor separation effect.

In some embodiments, as shown in FIGS. 16 and 17 , at least one of the partitions 321c is provided with at least one first opening 321k, and the first opening 321k is disposed in the middle or both ends of the partition 321c, and at least one of the other partitions The 321c is provided with at least two second openings 321m, and the second openings 321m and the first openings 321k are arranged in offset positions, wherein the first openings 321k and the second openings 321m respectively form the above-mentioned diversion openings 321d. That is, more than one opening can be provided on the partition 321c to reduce the wind resistance of the gas suction device when sucking the second suction channel 321; and there can be multiple partitions 321c with multiple openings, adjacent partitions The openings of the plate 321c are offset to form a curved path for the airflow. The size of the first opening 321k and the second opening 321m may be different.

In some embodiments, as shown in Figures 14-16 and 18, the partition 321c can be arranged obliquely, and the diversion port 321d can be set at the lowest point of the partition 321c, which can facilitate the partition 321c to block access to the second suction channel The liquid in 321 also ensures that the liquid entering the second suction channel 321 will flow out due to gravity when the main body 100 is tilted or upright.

In some embodiments, as shown in FIGS. 14-18 , a unit airflow channel 321e is formed between every two adjacent separators 321c, and the cross-sectional area of each unit airflow channel 321e gradually decreases along the airflow direction. The unit airflow channel 321e, along with the airflow direction, the cross-sectional area of the airflow channel gradually decreases so that the liquid entering the unit airflow channel 321e can easily impact on the inner wall of the unit airflow channel 321e, which can form a certain blocking effect on the liquid , so that the liquid can be blocked by a position with a smaller cross-sectional area, thereby reducing the probability of liquid entering the gas suction device 500 .

In some embodiments, as shown in FIGS. 14 and 15 , the minimum cross-sectional area of one of the two adjacent unit airflow passages 321e that is closer to the air inlet 321b is smaller than the maximum cross-sectional area of the other, so that The setting can make the size of the cross-sectional area of the airflow channel change periodically. Such a setting can make the velocity of the airflow entering the unit airflow channel 321e slow down when entering a region with a large cross-sectional area, and then be mixed in the airflow The liquid can fall under the action of gravity, which can assist gas-liquid separation and reduce the probability of liquid entering the gas suction device.

Exemplarily, as shown in FIG. 15 , the partition 321c includes first partitions 3211c and second partitions 3212c arranged alternately along the suction direction, wherein the second suction channel 321 has first partitions oppositely arranged along the left and right directions. The side wall 321f and the second side wall 321g, the first partition 3211c is arranged on the first side wall 321f of the second suction passage 321 and slopes downward toward the second side wall 321g, and the second partition 3212c is arranged on the second suction channel 321f. The second side wall 321g of the suction channel 321 slopes downward toward the first side wall 321f, so that the first partitions 3211c and the second partitions 3212c can both slope downwards and be staggered in the vertical direction.

Further, as shown in FIG. 15 , a baffle 3213c may be provided on the partition 321c, and the baffle 3213c is set at an included angle with the airflow direction to block the liquid entering the second suction channel 321 . By setting the baffle 3213c, at least part of the suction airflow can directly hit the baffle 3213c, and since the airflow carries water vapor, the water vapor hits the baffle 3213c and can flow down along the extending direction of the baffle 3213c, so that This serves to further reduce the risk of liquid entering the second suction device 500 through the second suction channel 321 .
