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

In some embodiments, the isolation chamber 10 may have an air intake hole 12 through the partition 11. Thereby, the reservoir chamber 20 can be pressurized from the 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). Thus, the air pump can control the air pressure in the reservoir 20 through the air inlet hole 12.

In this embodiment, the reservoir chamber 20 may be isolated from the isolation chamber 10 via the partition 11. Specifically, the partition plate 11 may be integrally formed with the water tank 1, whereby airtightness of the reservoir chamber 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 embodiments, the reservoir 20 may be used for storing other liquids such as detergent, sterilized water, and the like.

Fig. 3 is a schematic sectional view showing a connecting column 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 attachment post 21 has a proximal portion proximate the reservoir 20 and a distal portion distal 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 the inner wall of the reservoir chamber.

In some embodiments, the distal portion may have an umbrella-like 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 progressively in a distal-most direction. In this case, the distal end portion may completely block the conduit 50, whereby the airtightness between the conduit 50 and the connection column 21 can be improved. In other embodiments, the outer diameter of the distal portion may gradually shrink to an outer diameter that is consistent with the outer diameter of the proximal portion after the outer diameter of the distal portion reaches a maximum in the distal-most direction. In some embodiments, the outer diameter of the distal portion may be reduced to an outer diameter that is substantially the same as the outer diameter of the proximal portion after the outer diameter of the distal portion has reached a maximum in the distal-most direction.

In some embodiments, the connecting means of the conduit 50 and the connecting column 21 may be dispensing. In addition, the connection between the conduit 50 and the water outlet 31, the air column 22 and the air inlet 12 can 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, the first aperture 211 is located at the periphery of the proximal portion. In some embodiments, the first opening 211 may be disposed at and communicate with the bottom of the reservoir chamber 20 (see fig. 3). Specifically, the first opening 211 is in contact with the bottom at least in part, and in some embodiments, the first opening 211 may have an extent less than 180 ° of the outer circumference of the connecting column 21. In some embodiments, the depth of the first bore 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, the first opening 211 may be circular, triangular, or other irregular shape. In some embodiments, the second aperture 212 may be circular. In other embodiments, the second opening 212 may be rectangular, triangular, or other irregular shape.

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

In some embodiments, the connecting post 21 may have a central passage 213 for connecting the first and

second openings

211 and 212. At this time, the first opening hole 211 may have a slope connected with the central passage 213. In this case, the slope may facilitate the flow of liquid into the central passage 213, thereby enabling the flow of liquid to be facilitated. In other embodiments, the first opening 211 may be curved to connect with the central channel 213.

In some embodiments, the connecting post 21 may be disposed in a recess 23 in the bottom. In this case, the water in the reservoir chamber 20 is collected toward the groove 23, thereby preventing the water from remaining on 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 chamber 20 can flow through the first opening 211 in the bottom to the second opening 212 at the distal most end. In other embodiments, the second aperture 212 may be located anywhere on the distal portion. This enables the position of the second opening 212 to be adjusted as necessary.

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

In some embodiments, the reservoir 20 may also include an air column 22 of the same construction as the connecting column 21. In other embodiments, the gas column 22 may have a different structure than the connecting column 21. In particular, the difference may be that the first and second apertures may differ in position, size or shape. Thereby, the water can be pressurized by inflating the air through the inflating column 22, thereby improving controllability during pressurization and preventing backflow of water into the air intake holes 12.

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

In some embodiments, the air 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 in the compartment 10 can enter the conduit 50 through the air inlet 12, then follow the conduit 50 from the distal portion of the post 22 into the post 22, and finally enter the reservoir 20 from the proximal portion of the post 22.

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

In some embodiments, as shown in fig. 4, the bottom of the reservoir 20 may be provided with a water outlet module 30 connected to the connecting column 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 makes it possible to increase the amount of water discharged and to discharge water at an appropriate position as needed.

In some embodiments, the outlet module 30 may be located at a substantially middle position of the bottom of the reservoir chamber 20. In this case, the pressure difference due to the inclination can be reduced when the water tank 1 has a certain inclination, and thereby the possibility of liquid leakage can be reduced.

In some embodiments, the water outlet module 30 may have a flat portion 32 protruding from the bottom and a supporting portion 33 supporting the flat portion 32, and the water outlet 31 penetrates through the flat portion 32. In this case, the water outlet 31 is higher than the bottom, thereby increasing a pressure condition required for water discharge, thereby preventing water leakage.

In some embodiments, the support portion 33 may be integrally formed with the base portion. In some embodiments, the support portion 33 may cooperate with the shunt module 40 and form a shunt channel. In some embodiments, the support portion 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 flow dividing direction. In this case, the bottom portion has a recess formed by the support portion 33 protruding toward the inside of the reservoir 20 as viewed in the direction from the bottom portion to the flat portion 32, whereby the flow distribution module 40 can be detachably mounted in the recess to perform flow distribution.

In some embodiments, the inner side of the supporting 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 portion 34 does not exceed the plane of the base. In this case, the diversion module 40 may have a positioning column 44 matched with the position-limiting part 34, so that the positioning column 44 can be combined with the position-limiting part 34, and the diversion 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 extension 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 prevention capability.

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

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 an outer diameter size of the water outlet 31 after increasing to a predetermined outer diameter (hereinafter referred to as an umbrella structure 215). In other embodiments, the water outlet 31 may be provided with an umbrella-like structure 215 towards the inside of the water tank 1. In this case, the umbrella-shaped structure 215 may completely block the duct 50, thereby improving airtightness between the duct 50 and the outlet 31.

Fig. 5 is a schematic perspective view showing a flow distribution 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 center line of the tip portion 41 may be located in the same plane as the center axis of the water outlet 31. In this case, each drop of liquid flowing out of the water outlet 31 is cut and bisected by the tip portion 41, so that the liquid flowing out of the water outlet 31 can be divided, and the liquid can be uniformly discharged.

In some embodiments, the tip portion 41 may be in 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 tip portion 41 may coincide with the length and width of support portion 33 of water exit module 30.

In other embodiments, the tip portion 41 may have a cross shape, a meter shape, or other shapes as viewed from the direction from the water outlet 31 to the tip portion 41. In this case, the number of branches of the divided 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 divided into two, three, four or more flows as needed.

Fig. 6 is a schematic sectional view showing a water tank 1 according to an 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, the tip portion 41 may be tangential to the outlet 31. Additionally, in some embodiments, the tip portion 41 may be embedded in the outlet port 31.

In some embodiments, the flow diversion module 40 may have a flow guide channel 42 smoothly connected with the tip portion 41. Specifically, the flow guide channel 42 may match the tip portion 41. In this case, the flow guide passage 42 may have the same number of flow guide passages 42 as the number branched by the tip portion 41, whereby each of the liquids branched by the tip portion 41 may flow into the corresponding flow guide passage 42.

In some embodiments, the flow guide channel 42 may be a sloped surface. Specifically, the flow guide passage 42 may gradually decrease in inclination angle from the tip portion 41 to the end of the flow guide passage 42 with respect to the horizontal plane. This can facilitate the flow of liquid to the nozzle hole 43. In other embodiments, the flow guide channels 42 may be planar parallel to the horizontal plane.

In some embodiments, the flow dividing module 40 may have two outlet holes 43 communicating with the outside. Specifically, the outlet hole 43 may be disposed at an end of the flow guide passage 42 away from the tip portion 41. In other embodiments, a flow guide passage 42 may be provided with an outlet opening 43 at the end remote from the tip portion 41. This allows the liquid that has entered the guide passage 42 to uniformly flow out of the water outlet holes 43.

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

In addition, in some embodiments, one flow guide channel 42 may be provided with a plurality of outlet holes 43. In this case, the guide passage 42 can cope with a larger flow rate, and thus, the liquid entering the guide passage 42 can be discharged in time, and the possibility of occurrence of a reverse flow caused by an excessively large flow rate which cannot be discharged in time is reduced.

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 enables better coupling with the effluent module 30. In other embodiments, the diversion module 40 can be combined with the water outlet module 30 by dispensing. Additionally, in some embodiments, the diverter module 40 may be integrally formed with the exit module 30. This can improve the sealing property between the flow dividing module 40 and the water outlet module 30.

Additionally, in some embodiments, splitter module 40 may be a Y-tee. This can perform a function of dividing the flow.

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 distribution module 40 of a 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 water outlet module 30 'may have a water outlet 31' in the same plane as the inner side of the bottom of the water tank 1. In this case, the liquid in the liquid storage tank can directly flow out from the water outlet 31', so that the air pressure in the liquid storage tank can be controlled by controlling the air pump, and the liquid can be controlled to flow out from the water outlet 31'. In addition, since the water outlet 31' is located on the same plane as the inner side of the bottom of the water tank 1, the bottom of the water tank 1 may not be provided with the connection column 21 in this case.

In some embodiments, the water outlet module 30' may be provided in an embedded manner in a wall of the bottom of the water tank 1. In other embodiments, the water outlet module 30' may be protruded 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 outlet passage formed by the outlet 31'.

In some embodiments, the tip portion 41' of the flow diversion module 40' may correspond to the water outlet passage formed by the water outlet 31 '. In this case, the tip portion 41' can divide the liquid flowing out from the water outlet passage, and the divided liquid passes through the flow guide channel 42' and finally flows out from the water outlet hole 43 '.
