Fig. 1 is a schematic perspective view showing a water tank 1 according to an embodiment of the present invention.

As shown in fig. 1, the present invention provides a water tank 1 including an isolation chamber 10, a liquid storage chamber 20, a water outlet module 30, and a diverting module 40. The liquid storage chamber 20 may be isolated from the isolation chamber 10 via the partition 11, wherein, in addition, the bottom of the liquid storage chamber 20 may be provided with a water outlet module 30 connected with the connection column 21, the water outlet module 30 having at least one water outlet 31. The diverting module 40 may have a tip portion 41 corresponding to the water outlet 31 and further have a diverting passage 42 smoothly connected to the tip portion 41, wherein the diverting module 40 has at least two water outlet holes 43 communicating with the outside.

In this case, the liquid in the liquid storage chamber 20 can be transferred to the second opening through the first opening 211 of the connection column 21 and then transferred to the flow dividing module 40 through the water outlet 31, and the flow dividing module 40 divides the liquid of the water outlet 31 through the tip portion 41 and finally flows out of the water outlet 43 communicated with the outside, whereby only one water outlet 31 of the water tank 1 is affected by the air pressure, the air pressure of the water outlet 31 is not changed due to the inclination, and thus the leakage of the liquid can be prevented.

In some embodiments, the water tank 1 may also have an upper cover. In particular, the upper cover may have a shape matching the shape of the water tank 1, i.e. a shape similar to the projection of the water tank 1. When the upper cover is combined with the water tank 1, the isolation chamber 10 and the liquid storage chamber 20 are each formed as a closed space, respectively. In some embodiments, the upper cover may also have an injection port. Thus, after the upper lid is coupled to the water tank 1, the liquid can be injected through the injection port. In some embodiments, the injection port may be sealed by a cap or an inner cap.

Fig. 2 is a schematic plan view showing a water tank 1 according to an embodiment of the present invention.

As shown in fig. 2, in some embodiments, the isolation chamber 10 may be formed as a separate isolation space in the water tank 1. In this case, when the water tank 1 is filled with liquid, no liquid flows into the isolation chamber 10, and thus, the relevant charging components in the water tank 1 can be provided in the isolation chamber 10.

In some embodiments, the isolation chamber 10 may have an air inlet hole 12 through the partition 11. Thereby, the liquid storage chamber 20 can be pressurized from the air intake hole 12 by the pressurizing means in the isolation chamber 10.

In some embodiments, the isolation chamber 10 may have an air pump (not shown). Thereby, the air pump can control the air pressure in the liquid storage chamber 20 through the air intake hole 12. Specifically, the air pump may be an electric air pump, whereby air can be compressed by the electric air pump and injected into the liquid storage chamber 20.

In some embodiments, the isolation chamber 10 may also include a motor (not shown). In particular, the motor may be used to control the rotation of the mop, wipe or cleaning roller.

In other embodiments, the isolation chamber 10 may also have a power module (not shown). In some embodiments, the power module may be a battery pack. In other embodiments, the power supply module may be a power supply contact connectable with the cleaning robot 2. In this case, the power supply module may supply power to the respective components in the isolation chamber 10 by being connected to the cleaning robot 2.

In some embodiments, the isolation chamber 10 may also include a water level monitoring sensor (not shown). Specifically, the water level monitoring sensor may penetrate the partition 11 such that the power supply portion is located in the isolation chamber 10 and the sensor portion is located in the liquid storage chamber 20. In some embodiments, the water level monitoring sensor may be selected from one or more of a single flange static/dual flange differential pressure level transmitter, a float ball level transmitter, a magnetic level transmitter, a drop-in level transmitter, an electric inner float ball level transmitter, an electric float bowl level transmitter, a capacitive level transmitter, a magnetostrictive level transmitter, a servo level transmitter, a split ultrasonic level transmitter, or a radar level transmitter. In this case, the water level monitoring sensor may alarm when the water level in the liquid storage chamber 20 is low, thereby being able to remind the user to add the water purifying or cleaning agent in time.

In this embodiment, the reservoir 20 may be isolated from the isolation chamber 10 via the partition 11. Specifically, the partition plate 11 can be integrally formed with the water tank 1, whereby the air tightness of the reservoir 20 and the isolation chamber 10 can be improved. In some embodiments, the bottom of the reservoir 20 may be provided with a connecting post 21.

In some embodiments, the reservoir 20 may be used to store fresh water. However, the present embodiment is not limited thereto, and in other examples, the liquid storage chamber 20 may be used to store other liquids such as detergent, disinfectant, and the like.

Fig. 3 is a schematic cross-sectional view showing the connection post 21 of the water tank 1 according to the embodiment of the present invention.

As shown in fig. 3, in some embodiments, the reservoir 20 may be provided with a connecting post 21. The connecting column 21 has a proximal portion near the reservoir 20 and a distal portion remote from the reservoir 20, and a first opening 211 at the proximal portion and a second opening 212 at the distal portion, the first opening 211 communicating with the second opening 212. In some embodiments, the connecting post 21 may be disposed at the bottom of the reservoir 20. In other embodiments, the connecting post 21 may be disposed on an inner wall of the reservoir.

In some embodiments, the distal portion may have an umbrella structure 215. In particular, the distal portion may have a larger outer diameter than the proximal portion. Further, the distal portion may have an outer diameter that increases stepwise in a distal-most to distal direction. In this case, the distal end portion can completely block the catheter 50, whereby the air tightness between the catheter 50 and the connection post 21 can be improved. In other embodiments, the outer diameter of the distal portion may gradually shrink to an outer diameter consistent with the proximal portion after the outer diameter of the distal portion reaches a maximum in the distal-most to distal direction. Also in some embodiments, the outer diameter of the distal portion may shrink directly to an outer diameter consistent with the proximal portion when the outer diameter of the distal portion reaches a maximum in the distal-to-distal direction.

In some embodiments, the conduit 50 may be attached to the connecting post 21 by dispensing. In addition, the connection between the conduit 50 and the water outlet 31, the air charging post 22 and the air inlet 12 may be dispensing. In other embodiments, the conduit 50 may be connected to the components in one or more of nesting, clamping, spot welding, and heat shrinking.

In some embodiments, first opening 211 is located at the outer periphery of the proximal portion. In some embodiments, the first opening 211 may be disposed at and communicate with the bottom of the liquid storage chamber 20 (see fig. 3). Specifically, at least a portion of the first opening 211 is in contact with the bottom, and in some embodiments, the range of the first opening 211 may be less than 180 ° of the outer circumference of the connection post 21. In some embodiments, the depth of the first opening 211 may be less than the radius of the outer diameter of the connecting column 21.

In some embodiments, the first opening 211 may be rectangular. In other embodiments, first apertures 211 may be circular, triangular, or other irregular shapes. In some embodiments, the second aperture 212 may be circular. In other embodiments, the second apertures 212 may be rectangular, triangular, or other irregular shapes.

In some embodiments, the central axis of the first opening 211 may be perpendicular to the central axis of the connection post 21. In other embodiments, the central axis of the first opening 211 may be at an acute angle less than 90 ° to the central axis of the connecting post 21. In other embodiments, the central axis of the first opening 211 may form an obtuse angle greater than 90 ° with the central axis of the connecting post 21.

In some embodiments, the connecting post 21 may have a central channel 213 for connecting the first aperture 211 and the second aperture 212. At this time, the first opening 211 may have a slope connected with the central passage 213. In this case, the slope may facilitate the flow of the liquid into the central passage 213, thereby enabling the flow of the liquid to be facilitated. In other embodiments, first opening 211 may be curved in connection with central channel 213.

In some embodiments, the connection post 21 may be disposed in a recess 23 in the bottom. In this case, the water in the reservoir 20 is collected toward the groove 23, and thus, the water can be prevented from remaining at the bottom of the water tank 1.

In some embodiments, the second aperture 212 is located at the distal-most end of the distal portion. Thus, water in the reservoir 20 may flow through the bottom first opening 211 to the most distally located second opening 212. In other embodiments, the second aperture 212 may be located at any location on the distal portion. Thereby, the position of the second opening 212 can be adjusted as needed.

In some embodiments, the outer perimeter of the connection post 21 further includes a stiffener 214. This can improve the stability of the connection between the connection post 21 and the bottom. In some embodiments, the reinforcing ribs 214 may be connected to the bottom of the reservoir 20. Specifically, the reinforcing ribs 214 may be located at both sides of the first opening 211. In some embodiments, the ribs 214 may be rectangular and have a thickness less than the outer diameter of the connecting post 21. In other embodiments, the reinforcing ribs 214 may be, in some embodiments, uniformly distributed around the outer circumference of the connecting column 21.

In some embodiments, the reservoir 20 may further include an inflatable post 22 that is structurally identical to the connecting post 21. In other embodiments, the inflation post 22 may have a different structure than the attachment post 21. In particular, the difference may be that the positions of the first and second openings may be different, and the sizes or shapes may be different. Thereby, the water can be pressurized by inflating the air column 22, thereby improving the controllability during the pressurization and preventing the water from flowing back into the air intake hole 12.

In some embodiments, the inflatable column 22 may be disposed at the bottom of the reservoir 20. In other embodiments, the inflatable column 22 may be disposed on an inner wall of the reservoir 20.

In some embodiments, the inflatable column 22 may be connected to the air intake 12 via a conduit 50, such as by dispensing. In this case, the air pump located within the isolation chamber 10 may pass through the air intake port 12 into the conduit 50, then along the conduit 50 from the distal portion of the inflation post 22 into the inflation post 22, and finally from the proximal portion of the inflation post 22 into the reservoir 20.

Fig. 4 is a schematic bottom perspective view showing the water tank 1 according to the embodiment of the present invention.

As shown in fig. 4, in some embodiments, the bottom of the liquid storage chamber 20 may be provided with a water outlet module 30 connected to the connection post 21, and the water outlet module 30 has a water outlet 31. In other embodiments, the water outlet module 30 may have a plurality of water outlets 31. This can increase the water yield and can select water to be discharged at an appropriate place as needed.

In some embodiments, the water outlet module 30 may be located at a substantially central location at the bottom of the reservoir 20. In this case, the pressure difference caused by the inclination can be reduced when the water tank 1 has a certain inclination, and thus the possibility of leakage can be reduced.

In some embodiments, the water outlet module 30 may have a flat portion 32 protruding from the bottom and a support portion 33 supporting the flat portion 32, and the water outlet 31 penetrates the flat portion 32. In this case, the water outlet 31 is higher than the bottom, whereby the pressure condition required for the water to be discharged can be increased, thereby preventing the occurrence of water leakage.

In some embodiments, the support 33 may be integrally formed with the base. In some embodiments, the support 33 may cooperate with the flow splitting module 40 and form a flow splitting channel. In some embodiments, the support 33 may be composed of a plurality of curved surfaces. In other embodiments, the support portion 33 may be formed with a curved surface in the direction of split flow. In this case, the bottom has a recess formed by the support portion 33 protruding toward the inside of the liquid storage chamber 20 as seen in the direction from the bottom to the flat portion 32, whereby the flow dividing module 40 can be detachably mounted into the recess to thereby divide the flow.

In some embodiments, the inner side of the support portion 33 may have a stopper portion 34 protruding in a direction from the flat portion 32 to the bottom. In some embodiments, the height of the stop 34 does not exceed the plane of the bottom. In this case, the diverting module 40 may have a positioning post 44 matched with the limiting part 34, whereby the positioning post 44 can be combined with the limiting part 34, so that the diverting module 40 can be accurately matched with the water outlet module 30.

In some embodiments, the water outlet 31 protrudes from the flat portion 32 along the extending direction of the penetrating direction. In this case, the water outlet 31 may be formed with a water outlet passage, whereby the air pressure required for water outlet can be increased, thereby further improving the leakage preventing ability.

In some embodiments, the connection post 21 is connected to the water outlet module 30 by a conduit 50. Thereby, the passage between the connection post 21 and the water outlet module 30 can be lengthened, thereby increasing the pressure required for water outlet.

In some embodiments, both ends of the water outlet 31 may have an outer diameter gradually increasing in a direction from both ends to the flat portion 32, and gradually shrinking to the outer diameter size of the water outlet 31 after increasing to a predetermined outer diameter (hereinafter referred to as an umbrella-like structure 215). In other embodiments, the water outlet 31 may be provided with an umbrella structure 215 on the inside towards the water tank 1. In this case, the umbrella structure 215 may completely block the duct 50, whereby the air tightness between the duct 50 and the water outlet 31 can be improved.

Fig. 5 is a schematic perspective view showing a flow dividing module 40 of the water tank 1 according to the embodiment of the present invention.

As shown in fig. 5, in some embodiments, the diversion module 40 may have a tip portion 41 corresponding to the water outlet 31. Specifically, the tip portion 41 may divide the water outlet 31 uniformly as viewed in the direction of the central axis of the water outlet 31. Further, the midline of the tip portion 41 may be in the same plane as the central axis of the water outlet 31. In this case, each drop of liquid flowing out from the water outlet 31 is cut and divided equally by the tip portion 41, whereby the liquid flowing out from the water outlet 31 can be split, and the liquid can be discharged uniformly.

In some embodiments, the tip portion 41 may have a straight shape as viewed in a direction from the water outlet 31 to the tip portion 41. In some embodiments, the length and width of the tip portion 41 may be consistent with the length and width of the support portion 33 of the water outlet module 30.

In other embodiments, the tip portion 41 may have a cross shape, a rice shape, or the like, as viewed in a direction from the water outlet 31 to the tip portion 41. In this case, the number of branches of the split flow can be changed by changing the shape of the tip portion 41, whereby the liquid flowing out of the water outlet 31 can be split into two, three, four or more as needed.

Fig. 6 is a schematic cross-sectional view showing the water tank 1 according to the embodiment of the present invention.

As shown in fig. 6, in some embodiments, the tip portion 41 may be at a distance from the water outlet 31. In other embodiments, tip portion 41 may be tangential to water outlet 31. Additionally, in some embodiments, the tip portion 41 may be embedded in the water outlet 31.

In some embodiments, the diversion module 40 may have a diversion channel 42 that smoothly connects with the tip portion 41. Specifically, the diversion channel 42 may be matched with the tip portion 41. In this case, the diversion channels 42 may have the same number of diversion channels 42 as the number of diversion of the tip portion 41, whereby each of the liquid diverted by the tip portion 41 may flow into the corresponding diversion channel 42.

In some embodiments, the diversion channel 42 may be beveled. Specifically, the diversion channel 42 may gradually decrease in inclination angle from the horizontal from the tip portion 41 to the end of the diversion channel 42. This can facilitate the flow of the liquid to the water outlet holes 43. In other embodiments, the diversion channel 42 may be a plane parallel to the horizontal plane.

In some embodiments, the diverting module 40 may have two water outlets 43 in communication with the outside. Specifically, the water outlet hole 43 may be provided at the end of the diversion channel 42 remote from the tip portion 41. In other embodiments, a diversion channel 42 may be provided with a water outlet 43 at the end remote from the tip 41. Thereby, the liquid entering the diversion passage 42 can be uniformly discharged out of the water outlet holes 43.

In some embodiments, the inner diameter of the water outlet aperture 43 may be larger than the inner diameter of the water outlet 31. This facilitates ventilation and reduces the possibility of negative pressure. Specifically, the inner diameter of the water outlet hole 43 may be twice the inner diameter of the water outlet 31. In other embodiments, the inner diameter of the water outlet 43 may be equal to the inner diameter of the water outlet 31. Additionally, in some embodiments, the inner diameter of the water outlet aperture 43 may be smaller than the inner diameter of the water outlet 31.

Additionally, in some embodiments, one diversion channel 42 may be provided with a plurality of water outlets 43. In this case, the diversion channel 42 can cope with a larger flow rate, thereby enabling timely discharge of the liquid entering the diversion channel 42, and reducing the possibility of occurrence of a reverse flow condition due to excessive flow rate which cannot be timely discharged.

In some embodiments, the diversion channel 42 is provided with a positioning portion corresponding to the limiting portion 34 of the water outlet module 30. This can be better combined with the water outlet module 30. In other embodiments, the diverter module 40 may be dispensed with the dispensing module 30. Additionally, in some embodiments, the diverter module 40 may be integrally formed with the outlet module 30. This can improve the sealing property between the diversion module 40 and the water outlet module 30.

Additionally, in some embodiments, the split module 40 may be a Y-tee. This can act as a shunt.

Fig. 7 is a schematic bottom view showing a water tank 1 according to another embodiment of the present invention. Fig. 8 is a schematic perspective view showing a flow dividing module 40 of the water tank 1 according to another embodiment of the present invention.

As shown in fig. 7 and 8, the present invention further provides another embodiment, which is different from the first embodiment in that:

in some embodiments, the outlet module 30 'may have an outlet opening 31' that is coplanar with the bottom inside surface of the tank 1. In this case, the liquid in the liquid storage tank can directly flow out from the water outlet 31', and thus, the air pressure in the liquid storage tank can be controlled by controlling the air pump, and thus, the liquid can be controlled to flow out from the water outlet 31'. Further, since the water outlet 31' is located on the same plane as the inner side surface of the bottom of the water tank 1, the bottom of the water tank 1 may not be provided with the connection post 21 in this case.

In some embodiments, the water outlet module 30' may be provided in an embedded manner in the wall of the bottom of the tank 1. In other embodiments, the water outlet module 30' may be provided to protrude toward the outside of the water tank 1 in a direction perpendicular to the bottom of the water tank 1.

In some embodiments, the water outlet 31' is formed with a water outlet passage. Thereby, the liquid can be guided directly along the water outlet channel formed by the water outlet 31'.

In some embodiments, the tip portion 41' of the diversion module 40' may correspond to the outlet water passageway formed by the water outlet 31'. In this case, the tip portion 41' may split the liquid flowing out of the water outlet passage, and the split liquid may flow out of the water outlet hole 43' through the diversion passage 42 '.

Fig. 9 is a schematic diagram showing the configuration of the cleaning robot 2 according to the embodiment of the present invention.

As shown in fig. 9, in addition, another aspect of the present invention provides a cleaning robot 2 including the water tank 1 as above, characterized by a robot body to which the water tank 1 is mounted. In this case, the cleaning robot 2 can prevent the water tank 1 from leaking by being loaded with the water tank 1 as described above. The specific structure of the water tank 1 refers to the above embodiment, and since the cleaning robot 2 of this embodiment adopts all the technical solutions of all the embodiments, the cleaning robot also has all the beneficial effects brought by the technical solutions of the embodiments, and will not be described in detail herein.

In some embodiments, a small wheel may be added to the bottom of the tank 1. This allows the cleaning robot 2 to move.

While the invention has been described in detail in connection with the drawings and embodiments, it should be understood that the foregoing description is not intended to limit the invention in any way.
