[0002] As one of the important parts of a wet vacuum cleaner, the sewage tank is mainly used to collect the sucked sewage and garbage. Among them, the suction port of the existing sewage tank is usually opened at the bottom of the sewage tank and is set to a columnar structure protruding into the sewage tank, which will cause the airflow in the sewage tank to easily stir the liquid, so that the sewage in the sewage tank is sucked into the motor, which will not only cause the motor to be easily damaged, but also the sewage will be blown to the outside of the wet vacuum cleaner.

[0052] An embodiment of the present invention provides a sewage tank structure 100 for cleaning equipment, such as Figure 1 and Figure 2 As shown, the sewage tank structure 100 includes: a sewage tank 110, having a first flow channel 110a and a second flow channel 110b, the first flow channel 110a and the second flow channel 110b are both connected to the inside and outside of the sewage tank 110; the first flow channel 110a is used to divert the fluid flowing into the sewage tank 110 into multiple streams, and make the multiple streams of fluid collide in the sewage tank 110; the second flow channel 110b is used to discharge the gas in the sewage tank 110.

[0053] It should be noted that the first flow channel 110a and the second flow channel 110b of the sewage tank 110 both have an inlet and an outlet. The sewage tank structure 100 can be installed on a body 200 of a cleaning device (such as a wet vacuum cleaner). As an example, Figures 3 to 5As shown, the cleaning device includes: a body 200 and a suction generating device 300, a floor brush 400 and a connecting pipe 500 arranged on the body 200; the connecting pipe 500 includes a first end and a second end arranged opposite to each other, the first end is connected to the floor brush 400, and the second end is connected to the inlet of the first flow channel 110a of the sewage tank 110 of the sewage tank structure 100; the suction port of the suction generating device 300 is connected to the outlet of the second flow channel 110b of the sewage tank 110. It should be noted that Figure 4 The arrows other than those used to mark the numbers are used to indicate the flow direction of the fluid; Figure 5 The dotted arrows in the figure are used to indicate the flow direction of sewage and garbage mixed with gas, and the solid arrows other than those used to mark the numbers are used to indicate the flow direction of gas.

[0054] When the cleaning device cleans the floor, the suction generating device 300 generates vacuum suction to suck the sewage garbage on the floor through the connecting pipe 500 to the inlet of the first flow channel 100a of the sewage tank 100. The sewage garbage mixed with gas is divided into multiple streams through the first flow channel 100a and then flows to the interior of the sewage tank 110. During the process of each stream of sewage garbage mixed with gas flowing downward into the interior of the sewage tank 110, the sewage garbage and the gas are separated due to the difference in weight between the sewage garbage and the gas. During the separation process, each stream of sewage mixed with gas is counteracted in the sewage tank, so that the kinetic energy of each stream of sewage mixed with gas is reduced, offset or at least partially offset due to the counteracting, so that the sewage garbage flows smoothly into the sewage tank 110 and is separated. The incoming gas will collide with the gas in other fluid beams in the sewage tank 100, thereby reducing its own kinetic energy, making it easier for the suction generating device 300 to absorb the separated gas through the second flow channel 100b, preventing the gas from continuing to fall and mix with the sewage garbage and stirring the sewage garbage, and can effectively prevent the sewage garbage in the sewage tank 110 from being sucked into the suction generating device 300, which can not only avoid damage to the suction generating device 300, but also prevent the sewage garbage from being blown to the outside of the cleaning equipment, thereby improving the space utilization rate of the sewage tank 110.

[0055] It can be seen that the sewage tank structure 100 as described above can be applied to cleaning equipment. The first flow channel 110a of the sewage tank 110 can divert the fluid flowing into the sewage tank 110 into multiple streams and make the gases in the multiple streams counteract each other in the sewage tank 110. Then, after the sewage garbage mixed with gas is diverted into multiple streams through the first flow channel 100a, each stream of sewage garbage mixed with gas undergoes gas-liquid separation in the process of flowing downward into the sewage tank 110. In the separation process, each stream of sewage mixed with gas counteracts each other in the sewage tank, so that the kinetic energy of each stream of sewage mixed with gas is reduced and offset by each other due to the counteracting. The separated gas and the gas in the sewage tank 100 collide with each other in the second flow channel 100b, thereby reducing their own kinetic energy, making it easier for the suction generating device 300 to absorb the separated gas through the second flow channel 100b, preventing the gas from continuing to fall and mixing with the sewage and garbage and stirring the sewage and garbage, and effectively preventing the sewage and garbage in the sewage tank 110 from being sucked into the suction generating device 300, which not only avoids damage to the suction generating device 300, but also avoids the sewage and garbage from being blown to the outside of the cleaning equipment. Compared with the general operation mode that emphasizes the enhancement of the kinetic energy of the rotating airflow, the present invention reduces the kinetic energy of the disturbed water / airflow stream in the sewage tank 100, so that the sewage and garbage in the sewage tank 100 are not easily sucked into the suction generating device 300, thereby reducing the probability of damage to the suction generating device 300.

[0056] In some embodiments of the present invention, Figure 2 As shown, the first flow channel 110a has at least two diversion outlets 110c spaced apart from each other. In this way, sewage and garbage can be effectively diverted. The number of diversion outlets 110c is not specifically limited in the embodiment of the present invention, and the number can be an even number, for example Figure 2 The 2, 4, and 6 shown can of course also be an odd number, such as 3, 5, 7, etc.

[0057] Of course, in some other embodiments of the present invention, the number of the diversion outlets 110c of the first flow channel 110a can also be one, and the diversion outlets 110c are distributed in all directions facing themselves. This situation can be regarded as the first flow channel 110a having multiple diversion outlets 110c arranged along its own circumference, and two adjacent diversion outlets 110c are close to each other.

[0058] In some embodiments of the present invention, Figure 1 and Figure 2As shown, the sewage tank 110 includes: a box body 111 and a cover body 112. The box body 111 has a receiving cavity and one end of the box body 111 has a first opening communicating with the receiving cavity. The cover body 112 is arranged on one end of the box body 111 close to the first opening. The first flow channel 110a and the second flow channel 110b are arranged on the end of the box body 111 close to the opening or on the cover body 112. The cover body 112 is detachably arranged relative to the box body 111 so that the box body 111 can be removed for cleaning.

[0059] Alternatively, if Figure 2 As shown, the branch outlet 110c of the first flow channel 110a is distributed toward the side wall of the box body 111. In this way, it can prevent the sewage garbage mixed with gas from flowing directly to the bottom of the housing chamber of the box body 111 after flowing out from the branch outlet 110c of the first flow channel 110a, and can avoid suppressing the surging of the liquid surface in the box body 111, effectively preventing the sewage garbage from being blown away by the gas and brought into the suction generating device 300 or brought to the external environment; and it can also make the sewage garbage mixed with gas flow out from the branch outlet 110c of the first flow channel 110a and hit the side wall of the box body 111, which can improve the separation effect of gas and sewage garbage, and can also make the separated gas hit the side wall of the box body 111 and turn again to generate a cyclone gas collision in the opposite direction, so as to effectively suppress the kinetic energy of the gas in the box body 111.

[0060] Alternatively, if Figure 1 As shown, the inlet of the second flow channel 110b is distributed toward the side wall of the box 111. In this way, it is possible to better prevent the surge in the box 111 from entering the inlet of the second flow channel 110b, and prevent the sewage and garbage in the box 111 from flowing out to the external environment, thereby further improving the utilization rate of the storage space of the box 111.

[0061] Based on the premise that the sewage tank 110 includes a tank body 111 and a cover body 112, as Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the distance between the inlet of the second flow channel 110b and the bottom of the accommodating chamber is greater than the distance between the diverting outlet 110c of the first flow channel 110a and the bottom of the accommodating chamber. Since sewage and garbage are stored in the accommodating chamber of the box 111 during the cleaning process of the cleaning device, the movement of the cleaning device will cause a surge in the sewage stored inside the box 111. By increasing the distance between the second flow channel 100b and the bottom of the box 111, it is possible to better avoid the surge from entering the inlet of the second flow channel 100b, thereby further improving the utilization rate of the storage space of the box 111.

[0062] Specifically in some embodiments of the present invention, Figure 1 and Figure 2As shown, the side surface of the cover 112 close to the bottom of the accommodating chamber is an inclined surface, and the inclined surface has a relatively distributed high end and a low end, the second flow channel 110b is opened at the high end, and the first flow channel 110a is opened at the bottom end. By opening the second flow channel 110b at the high end of the inclined surface of the cover 112, the inlet of the second flow channel 110b can be as far away from the bottom of the box body 111 as possible within a limited space.

[0063] Based on the premise that the sewage tank 110 includes a tank body 111 and a cover body 112, as Figure 1 and Figure 2 As shown, in some embodiments of the present invention, the inlet of the second flow channel 110b is staggered with the branch outlet 110c of the first flow channel 110a, so as to avoid the fluid flowing out of the branch outlet 110b of the first flow channel 110a directly flowing out of the inlet of the second flow channel 100b.

[0064] Specifically in some embodiments of the present invention, Figure 2 As shown, the cover 112 has a second opening 112a and a third opening 112b; the cover 112 is provided with a flow divider 113 and an exhaust portion 114 protruding toward the inside of the accommodating cavity, the first flow channel 110a is opened on the flow divider 113 and communicates with the second opening 112a, and the second flow channel 110b is opened on the exhaust portion 114 and communicates with the third opening 112b. In this way, the first flow channel 110a and the second flow channel 110b can be directly processed on the cover 112 without increasing the thickness of the cover 112. It can be understood that the inlet of the first flow channel 100a is communicated with the second opening 112a of the cover 112, and the outlet of the first flow channel 100a is communicated with the accommodating cavity of the box 111; the inlet of the second flow channel 100b is communicated with the inner cavity of the box 111, and the outlet of the second flow channel 100b is communicated with the third opening 112b of the cover 112.

[0065] Alternatively, if Figure 1 and Figure 2 As shown, the inner wall of the box body 111 is smooth and flat. This type of box body 111 does not have any structure inside. Compared with the existing sewage tank whose suction port is usually opened at the bottom of the sewage tank and is arranged as a columnar structure protruding into the sewage tank, the sewage tank 100 of the present invention can accommodate more sewage and garbage, avoiding the user from frequently emptying the sewage tank during use, facilitating use and shortening the cleaning operation time.

[0066] Optionally, the diverter portion 113 and the exhaust portion 114 may be connected to the cover body 112 in an integrated manner.

[0067] Alternatively, if Figure 1As shown, the exhaust portion 114 and the diverter portion 113 are distributed on both sides of the axis of the housing 111, and the inlet of the second flow channel 110b is opened on the wall of the exhaust portion 114 away from the diverter portion 113 and is in a different direction from the diverter outlet 110c of the first flow channel 110a. In this way, the flow path of the gas separated from the sewage and garbage in the housing 111 can be increased, the collision time between the gas and the gas in other fluid beams can be prolonged, and the kinetic energy of the gas can be effectively suppressed.

[0068] Specifically in some embodiments of the present invention, Figure 1 As shown, the diverter 113 includes: a baffle 1131, the baffle 1131 is located below the second opening 112a, and the space between the baffle 1131 and the second opening 112a forms a first flow channel 110a; at least one end of the baffle 1131 is connected to the cover 112 or the exhaust portion 114. The sewage and garbage mixed in the baffle 1131 of the diverter 113 through the second opening 112a of the cover 112, so that part of the kinetic energy is offset, and then flow toward different ends of the baffle 1131 under the action of the suction generating device 300, thereby achieving beam splitting, wherein the baffle 1131 of the diverter 113 can also prevent the sewage and garbage in the sewage tank 110 from flowing out of the first flow channel 110a to the outside of the sewage tank 110.

[0069] Optionally, the baffle 1131 is in an L-shape, and the vertical section of the baffle 1131 is connected to the cover 112. In some other embodiments, the baffle 1131 is also in an L-shape, and one end of the baffle 1131 is connected to the exhaust portion 114.

[0070] Alternatively, if Figure 1 As shown, one end of the baffle 1131 extends away from the direction of the inlet of the second flow channel 110b. Among them, one end of the baffle 1131 is bent and protruded toward the second opening 112a, and the diversion outlet 110c of the first flow channel 110a is provided on the end of the diversion portion 113 that is axially distributed along the bend of one end of the baffle 1131. In this way, after the suction generating device 300 stops working, the residual sewage and garbage sucked into the first flow channel 100a can more easily flow obliquely downward by its own gravity through the diversion portion 113 of this type of structure. In addition, the diversion portion 113 also includes a mounting plate 1132, which is connected between the baffle 1131 and the cover body 112. Of course, in other examples, one end of the baffle 1131 can extend to fit with the side wall of the box body 111.

[0071] Specifically in some embodiments of the present invention, Figure 1 As shown, the exhaust part 114 is a shell structure, the inner cavity of the exhaust part 114 forms the second flow channel 110b and is covered at the third opening 112b. The exhaust part 114 of this structure is easy to process and also easy to install at the third opening 112b of the cover body 112.

[0072] In some embodiments of the present invention, Figure 2 As shown, the sewage tank structure 100 further includes: a filter assembly 120 disposed on the sewage tank 110, and the filter assembly 120 is used to filter the gas discharged from the outlet of the second flow channel 110b. The gas separated from the sewage and garbage is discharged through the second flow channel 100b and then filtered again by the filter assembly 120, which can further purify the gas, further effectively prevent the sewage or garbage mixed in the gas from being carried out by the gas, and prevent the discharged gas from clogging the suction generating device 300 due to carrying impurities, thereby preventing the suction generating device 300 from being damaged.

[0073] Furthermore, in some embodiments of the present invention, the sewage tank 110 has an outflow cavity corresponding to the outlet of the second flow channel 110b; Figure 1 As shown, the filter assembly 120 includes: a bracket 121 and a filter element 122. The bracket 121 is arranged on the sewage tank 110. The bracket 121 has a hollow portion corresponding to the outflow cavity, and the filter element 122 is arranged on the hollow portion. The bracket 121 with the hollow portion can stably support the filter element 122 to prevent the filter element 122 from being separated from the bracket. On the other hand, it is convenient for the gas flowing out of the second flow channel 100b to pass through the hollow portion of the bracket 121 and then be further filtered by the filter element 122 before being discharged to the external environment.

[0074] Optionally, the filter element 122 may be a filter sponge, which has the advantages of good elasticity, high filtration efficiency, low gas resistance, repeated washing, and low cost, and can effectively filter gas and save costs. In addition, in this embodiment, the shape of the filter element 122 is a regular shape and the outer wall is smooth and round, which is conducive to the cleaning of the filter element 122 and the cover body 112. For example, the shape of the filter element 122 is a semicircular shape, and correspondingly, the hollow portion of the bracket 121 is also a semicircular shape.

[0075] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the outer wall of the sewage tank 110 has a receiving groove 110d, which is used to receive the connecting pipe 500 of the cleaning device. The receiving groove 110d allows the connecting pipe 500 to fit the box body 111 and extend from the top of the box body 111, which can improve the compactness of the cleaning device.

[0076] Another embodiment of the present invention provides a sewage tank structure for a cleaning device, such as Figure 1 and Figure 2As shown, the sewage tank structure includes: a box body 111 and a cover body 112, one end of the box body 111 has an opening connected to its own accommodating cavity, and the cover body 112 is arranged on the end of the box body 111 close to the opening; the end of the box body 111 close to the cover body 112 or the cover body 112 is provided with a first flow channel 110a, and the first flow channel 110a is used to divert the fluid flowing into the box body 111 into multiple streams, and make the multiple streams of fluid offset each other in the box body 111.

[0077] The sewage tank structure 100 as described above can be applied to cleaning equipment. The first flow channel 110a of the sewage tank 110 can divert the fluid flowing into the sewage tank 110 into multiple streams and make the gas in the multiple streams counteract each other in the sewage tank 110. Then, after the sewage garbage mixed with gas is diverted into multiple streams through the first flow channel 100a, each stream of sewage garbage mixed with gas undergoes gas-liquid separation in the process of flowing downward into the sewage tank 110. In the separation process, each stream of sewage mixed with gas counteracts each other in the sewage tank, so that the kinetic energy of each stream of sewage mixed with gas is reduced and offset by counteracting each other. Or at least partially offset, so that the sewage garbage flows smoothly into the sewage tank 110, and the separated gas is collided with the gas in other fluid beams in the sewage tank 100, thereby reducing its own kinetic energy, so that the suction generating device 300 is more likely to absorb the separated gas through the second flow channel 100b, and prevent the gas from continuing to fall and mix with the sewage garbage and stir the sewage garbage, which can effectively prevent the sewage garbage in the sewage tank 110 from being sucked into the suction generating device 300, which can not only avoid damage to the suction generating device 300, but also prevent the sewage garbage from being blown to the outside of the cleaning equipment. Compared with the general operation mode that emphasizes the enhancement of the kinetic energy of the rotating airflow, the present invention reduces the kinetic energy of the disturbed water / air flow beam in the sewage tank 100, so that the sewage garbage in the sewage tank 100 is not easily sucked into the suction generating device 300, thereby reducing the probability of damage to the suction generating device 300.

[0078] Another embodiment of the present invention provides a cleaning device, which includes a body 200 and any one of the above-mentioned sewage tank structures 100 , wherein the sewage tank structure 100 is disposed on the body 200 .

[0079] As an example, the cleaning device may be a wet vacuum cleaner.

[0080] As an example, the sewage tank structure 100 is connected to the body 200 via a snap-fit ​​structure. Figure 2As shown, the snap-on structure includes: a snap 130, a spring 140 and a slot (not shown), wherein the snap 130 is connected to the cover 120 of the sewage tank 100 via the spring 140, and the slot is provided at a position in the body 200 corresponding to the snap 130, and the snap 130 and the slot are snap-connected, and have the characteristics of stable connection and easy disassembly. It can be understood that the sewage tank structure 100 is detachably connected to the body 200, and when the sewage tank structure 100 needs to be cleaned, the sewage tank structure 100 can be removed from the body 200 for cleaning, and has the characteristics of easy disassembly and easy installation. Optionally, as Figure 1 and Figure 2 As shown, a handle 150 is provided on the outer wall of the box body 111 of the sewage tank 110 , and the handle 150 is convenient for pushing and pulling the sewage tank 110 , and is conducive to the disassembly and assembly of the sewage tank 110 .

[0081] In the cleaning device as described above, the first flow channel 110a of the sewage tank 110 of the sewage tank structure 100 can divert the fluid flowing into the sewage tank 110 into multiple streams and make the gases in the multiple streams counteract each other in the sewage tank 110. Then, after the sewage garbage mixed with gas is diverted into multiple streams through the first flow channel 100a, each stream of sewage garbage mixed with gas undergoes gas-liquid separation in the process of flowing downward into the sewage tank 110. In addition, in the separation process, each stream of sewage mixed with gas counteracts each other in the sewage tank, so that the kinetic energy of each stream of sewage mixed with gas is reduced, offset or even mutually increased due to the counteracting. A small part of the gas is offset, so that the sewage garbage flows smoothly into the sewage tank 110, and the separated gas is offset with the gas in other fluid beams in the sewage tank 100, thereby reducing its own kinetic energy, so that the suction generating device 300 is more likely to absorb the separated gas through the second flow channel 100b, and prevent the gas from continuing to fall and mix with the sewage garbage and stir the sewage garbage, which can effectively prevent the sewage garbage in the sewage tank 110 from being sucked into the suction generating device 300, which can not only avoid damage to the suction generating device 300, but also prevent the sewage garbage from being blown to the outside of the cleaning equipment. Compared with the general operation mode that emphasizes the enhancement of the kinetic energy of the rotating airflow, the present invention reduces the kinetic energy of the disturbed water / air flow beam in the sewage tank 100, so that the sewage garbage in the sewage tank 100 is not easily sucked into the suction generating device 300, thereby reducing the probability of damage to the suction generating device 300.

[0082] Furthermore, in some embodiments of the present invention, the cleaning device further comprises: a suction generating device 300, a floor brush 400 and a connecting pipe 500 arranged on the machine body 200; the connecting pipe 500 comprises a first end and a second end arranged opposite to each other, the first end is connected to the floor brush 400, and the second end is connected to the inlet of the first flow channel 110a of the sewage tank 110 of the sewage tank structure 100; the suction port of the suction generating device 300 is connected to the outlet of the second flow channel 110b of the sewage tank 110. The sewage garbage mixed with gas after being scrubbed by the floor brush 400 can enter the accommodating cavity of the box body 111 through the first flow channel 100a along the connecting pipe 500 under the suction of the suction generating device 300, and the separated gas is discharged from the sewage tank structure 100 through the second flow channel 100b, and then discharged to the external environment through the suction generating device 300.

[0083] Optionally, the cleaning device further includes a power supply 700, which is disposed in the body 200 and is used to power the floor brush 400 and the suction generating device 300. It should be noted that in other embodiments, the cleaning device can also be powered by mains electricity, which is not particularly limited here. It should be noted that the body 200 has a housing cavity (not shown), and the suction generating device 300 and the power supply 700 are both accommodated in the housing cavity.

[0084] Optionally, the suction generating device 300 is located above the second flow channel 110b and the suction port of the suction generating device 300 corresponds to the outlet of the second flow channel 110b. In this way, the suction generating device 300 is conducive to sucking out the gas in the sewage tank 100. A hollow or mesh structure is formed at the bottom end of the body 200 at a position corresponding to the outlet of the second flow channel 100b, and the body 200 is provided with an outlet connected to the accommodating cavity.

[0085] Alternatively, if Figure 5 As shown, the cleaning device also includes: a first sealing member 610 disposed at the connection between the sewage tank structure 100 and the second end of the connecting pipe 500, and the first sealing member 610 surrounds the four sides of the inlet of the first flow channel 110a. By setting the first sealing member 610, the sealing performance of the connection between the connecting pipe 500 and the sewage tank structure 100 is improved, and the gas mixed in the sewage and garbage is prevented from flowing out from the connection between the connecting pipe 500 and the sewage tank structure 100. The first sealing member 610 can be disposed at the pipe mouth of the second end of the connecting pipe 500 or on the bracket 121 of the filter assembly 120. Optionally, the first sealing member 610 can be a rubber ring, which can be fixed by bonding.

[0086] Alternatively, if Figure 1As shown, the cleaning device further includes: a second sealing member 620 disposed at the connection between the sewage tank structure 100 and the body 200, and the second sealing member 620 surrounds the outlet of the second flow channel 110b. The second sealing member 620 can be disposed on the bracket 121 of the filter assembly 120 or on the body 200. By disposing the second sealing member 620, the sealing performance of the connection between the outlet of the second flow channel 100b of the sewage tank structure 100 and the body 200 can be improved, so as to avoid affecting the adsorption effect of the suction generating device 300.

[0087] Optionally, the cleaning device further includes: a clean water tank 800; the clean water tank 800 is disposed on the machine body 200, and the clean water tank 800 is connected to the floor brush 400 through a water pipe, so as to spray water to the floor brush 400 to provide a water source for scrubbing the floor.

[0088] Optionally, the cleaning device further includes: a handle 900, which is disposed at the top of the body 200 to facilitate holding during cleaning and improve comfort of use.

[0089] Optionally, the cleaning device further includes: a power button, which is disposed on the handle and is electrically connected to the power source 700 to facilitate controlling the working state of the cleaning device.

[0090] Another embodiment of the present invention provides a sewage tank structure 100, such as Figure 1 and Figure 2 As shown, the sewage tank structure 100 includes a tank body 111 and a tank cover assembly. The tank cover assembly is arranged on the top of the tank body 111.

[0091] Specifically, Figure 1 and Figure 2 As shown, the box body 111 has a accommodating cavity. It can be understood that the box body 111 can be specifically in the shape of a cup. There is no other structure in the accommodating cavity of the box body 111, and the inner wall of the accommodating cavity is smooth and rounded for easy washing. One end (specifically the top) of the box body 111 is provided with an opening connected to the accommodating cavity; the box cover assembly includes a cover 112 and a first flow channel 100a; the cover 112 is arranged at one end (specifically the top) of the box body 111 close to the opening; it can be understood that the cover 112 of the box cover assembly covers the box body 111 so that the box body 111 forms a sealed space; and the cover 112 can be specifically detachably arranged relative to the box body 111, so that the box body 111 can be removed and cleaned. The first flow channel 100a is connected to the cover 112 and the accommodating cavity; an even number of diversion outlets 110c are arranged at the end of the first flow channel 100a.

[0092] The fluid flowing in from the first flow channel 100a is split into a number of fluid beams equal to the number of the split outlets 110c and forms a plurality of fluid beams in pairs, and the kinetic energy carried by each plurality of fluid beams is equal in pairs. It should be noted that the situation where the kinetic energy carried by each plurality of fluid beams is equal in pairs includes that the kinetic energy carried by each plurality of fluid beams is completely equal or substantially equal in pairs.

[0093] It can be understood that the working principle of the sewage tank structure 100 is roughly as follows: a fluid such as sewage and garbage mixed with gas enters the cover body 112 under the action of suction and flows through the first flow channel 100a, and hits the inner tube wall of the first flow channel 100a to divert the sewage and garbage mixed with gas in the first flow channel 100a, and is diverted through the diversion outlet 110c into fluid beams equal in number to the diversion outlet 110c and form paired multiple fluid beams, each of which flows into the containing chamber and impacts each other to separate the gas mixed with the sewage and garbage, wherein the sewage and garbage enter the bottom of the containing chamber of the box body 111 under the action of the inertia of gravity, and the gas is discharged into the external environment.

[0094] In summary, compared with the prior art, the sewage tank structure 100 has at least the following beneficial effects: the sewage tank structure 100 is provided with a first flow channel 100a on the cover body 112 covering the box body 111, so that a fluid such as sewage and garbage mixed with gas can enter the accommodating cavity of the box body 111 from the first flow channel 100a, and the gas is separated from the sewage and garbage and discharged into the external environment, and the first flow channel 100a is provided on the cover body 112 of the box cover assembly, which can simplify the internal structure of the box body 111, reduce the occupied space, and facilitate cleaning. In addition, the fluid, such as sewage garbage mixed with gas, flows from the cover 112 through the first flow channel 100a under the action of suction, and is divided into a number of fluid beams equal to the number of the diversion outlets 110c through the diversion outlet 110c of the first flow channel 100a and forms a pair of multiple fluid beams, each of which flows into the accommodating chamber and impacts each other to produce cyclone gas collisions in opposite directions, thereby suppressing the mutual kinetic energy of the gas and sewage garbage in the box 111, suppressing the surging of the liquid level in the accommodating chamber of the box 111, effectively preventing the sewage garbage from being blown away by the gas and brought into the motor or brought to the external environment, and improving the separation degree of gas and sewage garbage. In short, the sewage tank structure 100 has the characteristics of simple structure, large storage space, easy cleaning, and high separation degree of gas and sewage garbage.

[0095] In some embodiments, the box cover assembly further includes a second flow channel 110b, and the second flow channel 110b is connected to the cover body 112 and the accommodating cavity;

[0096] In the accommodating chamber, multiple fluid beams collide with each other to separate the gas entrained therein, and the separated gas can flow to the outside through the second flow channel 110b. It can be understood that the second flow channel 110b is arranged on the cover 112 of the box cover assembly, which can simplify the internal structure of the box 111, reduce the occupied space, and facilitate cleaning. And each multiple fluid beam flows into the accommodating chamber and collide with each other to separate the gas entrained in the sewage and garbage, wherein the sewage and garbage enter the bottom of the accommodating chamber of the box 111 under the inertia of gravity, and the gas can be smoothly discharged to the external environment through the second flow channel 110b.

[0097] In some embodiments, Figure 2 As shown, all the branch outlets 110c of the first flow channel 100a are oriented toward the side wall of the box body 111. It can be understood that the fluid, such as sewage garbage mixed with gas, flows into the first flow channel 100a from the cover body 112 under the action of suction. Under the action of suction and the inertia of the gravity of the sewage garbage, the sewage garbage entering the first flow channel 100a will be divided into equal number of fluid beams of the branch outlets 110c when hitting the inner tube wall of the first flow channel 100a, and form a pair of multiple fluid beams, and flow into the containing chamber through the corresponding branch outlets 110c respectively. After entering the containing chamber, the fluid beams in each of the multiple fluid beams are turned again after being ejected to the side wall of the box body 111 to produce a cyclone gas collision in the opposite direction, so as to suppress the mutual kinetic energy of the gas and the sewage garbage in the box body 111, suppress the surging of the liquid surface in the containing chamber of the box body 111, effectively prevent the sewage garbage from being blown away by the gas and brought into the motor or brought to the external environment, and improve the water-gas separation effect.

[0098] In some embodiments, the inlet of the second flow channel 110b faces the side wall of the box 111, which can better prevent the surge in the box 111 from entering the inlet of the second flow channel 110b, thereby further improving the utilization rate of the storage space of the box 111. It should be noted that the inlet of the second flow channel 110b and the diversion outlet 110c of the first flow channel 100a are staggered to prevent the fluid flowing out of the diversion outlet 110c of the first flow channel 100a from flowing directly out of the inlet of the second flow channel 110b.

[0099] In some embodiments, Figure 1 and Figure 2As shown, the top end surface of the cover 112 is an inclined surface, the cover 112 includes a lower end and a higher end connected to the lower end, and the second flow channel 110b is correspondingly arranged at the higher end of the cover 112. It should be noted that the lower end of the cover 112 refers to the end of the top end surface of the cover 112 that is shortest from the bottom of the box 111, and the higher end of the cover 112 refers to the end of the top end surface of the cover 112 that is longest from the bottom of the box 111. It can be understood that, since during the cleaning process of a cleaning device such as a vacuum cleaner, sewage and garbage will be stored in the accommodating cavity of the box 111, the movement of the vacuum cleaner will cause a surge in the sewage stored inside the box 111; by arranging the second flow channel 110b at the higher end of the cover 112, the inlet of the second flow channel 110b is as far away from the bottom of the box 111 as possible within a limited space, so that the surge entering the inlet of the second flow channel 110b can be better avoided, thereby further improving the utilization rate of the storage space of the box 111.

[0100] In some embodiments, Figure 1 As shown, the box cover assembly further includes a filter assembly 120 ; the filter assembly 120 includes a bracket 121 and a filter element 122 .

[0101] like Figure 1 and Figure 2 As shown, corresponding to the outlet position of the second flow channel 110b, the end of the cover body 112 away from the box body 111 has an outflow cavity for allowing the separated gas to flow out; the bracket 121 is arranged on the cover body 112. Specifically, the bracket 121 can be an integrally formed structure or a split structure with the cover body 112, and no special restrictions are made here. A hollow portion (not shown) is provided on the bracket 121, and the filter element 122 is provided on the hollow portion of the bracket 121. It can be understood that by forming a hollow portion on the bracket 121 at a position corresponding to the outflow cavity, the bracket 121 provided with the hollow portion can, on the one hand, stably carry the filter element 122 to prevent the filter element 122 from detaching from the bracket 121, and on the other hand, it is convenient for the gas flowing out of the second flow channel 110b to pass through the hollow portion of the bracket 121 and then be further filtered by the filter element 122 before being discharged to the external environment. It can be understood that the gas separated from the sewage and garbage is discharged through the second flow channel 110b and then filtered again through the filter element 122, which can further purify the gas and further effectively prevent the sewage or garbage mixed in the gas from being carried out through the gas. It should be noted that in this embodiment, the filter element 122 can be a filter sponge, which has the advantages of good elasticity, high filtration efficiency, low gas resistance, repeated washing, and low cost. It can effectively filter the gas and save costs. In addition, in this embodiment, the filter element 122 is semicircular in shape, and correspondingly, the hollow portion of the bracket 121 is also semicircular in shape.

[0102] Based on the above-mentioned sewage tank structure 100, the embodiment of the present invention further provides a vacuum cleaner, such as Figures 3 to 5 As shown, the vacuum cleaner includes a body 200 and the above-mentioned sewage tank structure 100, and the sewage tank structure 100 is vertically detachably connected to the body 200. It should be noted that in this embodiment, the sewage tank structure 100 is connected to the body 200 through a snap-on structure; specifically, the snap-on structure includes a buckle 130, a spring 140 and a slot (not shown), wherein the buckle 130 is connected to the cover 112 through the spring 140, and the slot is provided on the body 200 corresponding to the position of the buckle 130, and the buckle 130 and the slot are snap-connected, which has the characteristics of stable connection and easy disassembly. It can be understood that the sewage tank structure 100 is detachably connected to the body 200, and when the sewage tank structure 100 needs to be cleaned, the sewage tank structure 100 can be removed from the body 200 for cleaning, which has the characteristics of easy disassembly and easy installation.

[0103] In summary, compared with the prior art, the vacuum cleaner has at least the following beneficial effects: the vacuum cleaner adopts the above-mentioned sewage tank structure 100, and arranges a first flow channel 100a on the cover body 112 covering the box body 111, so that a fluid such as sewage and garbage mixed with gas can enter the accommodating cavity of the box body 111 from the first flow channel 100a, and the gas is separated from the sewage and garbage and discharged into the external environment, and the first flow channel 100a is arranged on the cover body 112 of the box cover assembly, which can simplify the internal structure of the box body 111, reduce the occupied space, and facilitate cleaning. In addition, the fluid such as sewage garbage mixed with gas flows from the cover 112 through the first flow channel 100a under the action of suction, and is divided into a number of fluid beams equal to the number of the diversion outlets 110c through the diversion outlet 110c of the first flow channel 100a and forms a pair of multiple fluid beams, each of which flows into the accommodating chamber and impacts each other to produce cyclone gas collisions in opposite directions, thereby suppressing the mutual kinetic energy of the gas and sewage garbage in the box 111, suppressing the surging of the liquid level in the accommodating chamber of the box 111, effectively preventing the sewage garbage from being blown into the motor or brought to the external environment by the gas, and improving the separation degree of gas and sewage garbage. In short, the vacuum cleaner has the characteristics of simple structure, large storage space, easy cleaning, and high separation degree of gas and sewage garbage.

[0104] In some embodiments, Figure 3 and Figure 4As shown, the vacuum cleaner further includes a floor brush 400, a connecting pipe 500 and a suction generating device 300; the floor brush 400, the sewage tank structure 100 and the suction generating device 300 are sequentially installed on the body 200 from bottom to top; wherein the floor brush 400 is used to scrub the floor, and the sewage tank structure 100 is used to store sewage and garbage after scrubbing the board; the suction generating device 300 is used to generate suction so that the sewage and garbage mixed with gas after scrubbing by the floor brush 400 enter the sewage tank structure 100 and flow out of the sewage tank structure 100. It should be noted that the body 200 has a receiving cavity (not shown), the suction generating device 300 and the power supply 700 are both received in the receiving cavity, and the suction port of the suction generating device 300 is aligned with the bottom end of the body 200; corresponding to the position of the outlet of the second flow channel 110b, the bottom end of the body 200 forms a hollow or mesh structure, and the body 200 is provided with an air outlet connected to the receiving cavity. The connecting pipe 500 includes a first end and a second end connected to the first end, that is, opposite ends of the connecting pipe 500. The first end of the connecting pipe 500 is connected to the floor brush 400, and the second end of the connecting pipe 500 is connected to the box cover assembly of the sewage tank structure 100, and the second end of the connecting pipe 500 is connected to the inlet of the first flow channel 100a. The sewage and garbage mixed with gas after being scrubbed by the floor brush 400 can enter the accommodating cavity of the box body 111 through the first flow channel 100a along the connecting pipe 500 under the suction of the suction generating device 300 to form mutually offset liquid flows, so that the gas is separated therefrom and rises to the upper part of the accommodating cavity, and is discharged from the sewage tank structure 100 through the second flow channel 110b, and then enters the accommodating cavity and flows out through the air outlet.

[0105] In some embodiments, Figure 1 and Figure 2 As shown, in order to improve the compactness of the structure, along the length direction of the body 200, the edge of the box body 111 is recessed toward the central axis direction of the box body 111 to form a groove 110e for accommodating the connecting pipe 500, so that the connecting pipe 500 can be set in close contact with the box body 111 and extend from the top of the box body 111.

[0106] In some embodiments, Figure 4 As shown, the vacuum cleaner further includes a power supply 700, which is disposed in the body 200 and is used to supply power to the floor brush 400 and the suction generating device 300. It should be noted that in other embodiments, the vacuum cleaner may also be powered by mains electricity, which is not particularly limited herein.

[0107] In some embodiments, Figure 5As shown, the vacuum cleaner further includes a first sealing member 610, which is disposed at the connection between the connecting pipe 500 and the box cover assembly; it should be noted that the first sealing member 610 can be specifically disposed at the pipe opening of the connecting pipe 500 or on the box cover assembly. It can be understood that by disposing the first sealing member 610, the sealing performance of the connection between the connecting pipe 500 and the box cover assembly is improved, and the gas mixed in the sewage and garbage is prevented from flowing out from the connection between the connecting pipe 500 and the box cover assembly.

It should be noted that the second sealing member 620 can be specifically disposed at the outlet of the second flow channel 110b or disposed on the machine body 200. It can be understood that by disposing the second sealing member 620, the sealing performance of the connection between the outlet of the second flow channel 110b of the sewage tank structure 100 and the machine body 200 can be improved, so as to avoid affecting the adsorption effect of the suction generating device 300.

[0109] In some embodiments, Figure 3 As shown, the vacuum cleaner further includes a clean water tank 800; the clean water tank 800 is disposed on the body 200, and the clean water tank 800 is connected to the floor brush 400 through a water pipe, so as to spray water to the floor brush 400, providing a water source for scrubbing the floor.
