[0046] Please refer to Figure 1 and Figure 2 Some embodiments of the present application provide a water tank assembly 100. The water tank assembly 100 includes a box body 10 and an anti-overflow portion 20. The box body 10 has a water injection chamber 11 and a water injection port 12, and the water injection port 12 is connected to the water injection chamber 11. The anti-overflow portion 20 is arranged on the outer surface of the box body 10, at least around a part of the water injection port 12, and the anti-overflow portion 20 includes a plurality of drainage portions 21 and at least one first connecting portion 22, the first connecting portion 22 connects two adjacent drainage portions 21, and the plurality of drainage portions 21 are distributed at intervals along the circumference of the water injection port 12, and each drainage portion 21 is connected to the water injection chamber 11.

[0047] The shape of the box body 10 may be, but is not limited to, a cylindrical shape or a hexahedron. The anti-overflow portion 20 may be disposed on the box body 10 , and the anti-overflow portion 20 may be integrally formed with the box body 10 .

[0048] The water tank assembly 100 is described below in conjunction with an actual application scenario of injecting water into the water tank assembly 100 .

[0049] like Figure 1 and Figure 2 As shown, when the user injects water into the water injection chamber 11 through the water injection port 12, the water in the water injection chamber 11 will shake, and some water can splash onto the anti-overflow portion 20 disposed around the water injection port 12. Because two adjacent drainage portions 21 of the anti-overflow portion 20 are connected through the first connecting portion 22, if water splashes onto the first connecting portion 22, it can flow to the drainage portion 21 next to the first connecting portion 22, and flow into the water injection chamber 11 from the drainage portion 21. If water splashes onto the drainage portion 21, it can flow directly from the drainage portion 21 into the water injection chamber 11.

[0050] In the above scheme, the anti-overflow part 20 is arranged around the water injection port 12, and the water splashed around the water injection port 12 is collected by the anti-overflow part 20, so that the water can flow back into the water injection cavity 11 through the drainage part 21 of the anti-overflow part 20, thereby reducing the probability of the water in the water injection cavity 11 splashing to the outside of the box body 10. Since there is no overflowing water stain on the outside of the box body 10, the user does not need to clean it, which can reduce the user's workload.

[0051] like Figure 2As shown, in some embodiments, the anti-overflow portion 20 is configured as a groove formed on the outer surface of the box body 10. This configuration simplifies the difficulty of preparing the anti-overflow portion 20.

[0052] In some embodiments, Figure 2 As shown, the plurality of drainage portions 21 include a first drainage portion 211 . At the end of the groove in the extending direction, a notch is provided on the groove wall of the groove, and the notch forms the first drainage portion 211 .

[0053] When water splashes into the groove, if it falls near the first drainage portion 211, it can flow into the water injection cavity 11 through the first drainage portion 211. Because the first drainage portion 211 is provided in the extending direction of the groove, different parts of the groove can be drained at the same time, improving the drainage performance of the groove.

[0054] Please continue reading Figure 2 In some embodiments, the plurality of drainage portions 21 further include a second drainage portion 212, the second drainage portion 212 and the first drainage portion 211 are spaced apart, the groove includes a first groove and a second groove connected to each other, the bottom wall of the first groove is recessed to form the second groove, the groove wall of the second groove is provided with a first drainage hole 2121, the first drainage hole 2121 is connected to the water injection cavity 11, and the second groove and the first drainage hole 2121 form the second drainage portion 212.

[0055] For example, in Figure 2 In the example shown, the side wall of the first groove is provided with a notch, which can form a first drainage portion 211, the bottom wall of the first groove forms a second groove, and the groove wall of the second groove is provided with a first drainage hole 2121. Water falling into the first groove, if it is close to the first drainage portion 211, can flow into the water injection cavity 11 through the first drainage portion 211. If it is close to the second groove, it can first flow from the first groove to the second groove, and then flow into the water injection cavity 11 from the first drainage hole 2121 of the second groove.

[0056] In this way, by designing the internal structure of the groove, additional ways of discharging water inside the groove into the water injection chamber 11 are added, so that different parts of the groove can be connected to the water injection chamber 11, thereby accelerating the discharge speed of water inside the groove into the water injection chamber 11.

[0057] See also Figure 2 and Figure 3 In some embodiments, the plurality of drainage portions 21 further include a third drainage portion 213, a protrusion is provided in the groove, the height of the outer peripheral portion of the protrusion is lower than the height of the middle portion, and the groove wall of the groove is further provided with a second drainage hole 2131 around the protrusion, the second drainage hole 2131 is connected to the water injection cavity 11, and the protrusion and the second drainage hole 2131 form the third drainage portion 213.

[0058] exist Figure 2 and Figure 3 In the example shown, the third drainage portion 213 may be disposed in the middle of the groove. When water falls into the third drainage portion 213, it may flow to the periphery of the protrusion under the action of its own gravity, and then flow into the second drainage hole 2131, and then flow into the water injection cavity 11 through the second drainage hole 2131. The water bypassing the second drainage hole 2131 may flow in the direction of the first drainage hole 2121, and then flow into the water injection cavity 11 through the first drainage hole 2121. If some water still bypasses the second drainage hole 2131, it may then flow to the first drainage portion 211, and then flow into the water injection cavity 11 through the first drainage hole 2121.

[0059] In some embodiments, Figure 4 As shown, the water tank assembly 100 further includes a flip cover 30 which is flippably mounted on the tank body 10 . The flip cover 30 has a closed state covering the water inlet 12 and the anti-overflow portion 20 and an open state exposing the water inlet 12 and the anti-overflow portion 20 .

[0060] The flip cover 30 may be transparent, and the flip cover 30 may be snap-fitted with the box body 10. For example, a positioning rib may be provided on the box body 10, and the snap rib of the flip cover 30 may be snap-fitted with the positioning rib. In this way, the user can act on the flip cover 30 to switch the state of the flip cover 30.

[0061] When the user flips the flip cover 30 to an open state, water can be poured into the water injection portion. The flip cover 30 can also shield water splashing out of the water injection portion to reduce the probability of water splashing to the outside of the box body 10.

[0062] In some embodiments, the flip cover 30 includes an opening side 31 and a connecting side 32 , the connecting side 32 is connected to the box body 10 , and the plurality of drainage portions 21 are disposed corresponding to the connecting side 32 .

[0063] When the flip cover 30 is in the open state, if there are water droplets attached to the surface of the flip cover 30 facing the box body 10, the water droplets can flow along the surface of the flip cover 30 under the action of their own gravity, flow to the connecting side 32 and fall into the drainage part 21, and finally flow into the water injection cavity 11 through the drainage part 21.

[0064] Such an arrangement reduces the probability that water droplets attached to the flip cover 30 are gathered at the connection between the flip cover 30 and the box body 10 and cannot be discharged smoothly.

[0065] The opening side 31 of the flip cover 30 is provided with a hand-held portion, which is convenient for the user to operate by hand. The connection side 32 is also provided with a buckle, and the box body 10 is also provided with a slot. When the flip cover 30 is in a closed state, the buckle and the slot are engaged, which improves the sealing performance of the flip cover 30 covering the water injection port 12, and reduces the probability of the flip cover 30 being separated from the box body 10 under the action of external force, thereby exposing the water injection port 12.

[0066] In addition, a sealing ring is provided on the side of the flip cover 30 facing the box body 10 , which can further improve the sealing performance of the flip cover 30 covering the water inlet 12 when the flip cover 30 is in a closed state.

[0067] In some embodiments, Figure 3 As shown, the anti-overflow portion 20 further includes a second connecting portion 23, which extends from the connecting side 32 to the opening side 31, and the second connecting portion 23 is connected to the water injection port 12. When the water in the water injection chamber 11 splashes onto the second connecting portion 23, it can flow into the water injection chamber 11 through the second connecting portion 23, thereby reducing the probability that the water in the water injection chamber 11 splashes from the opening side 31 to the outside of the box body 10.

[0068] Specifically, in some embodiments, the second connecting portion 23 is connected to the drainage portion 21. In other words, the first connecting portion 22, the second connecting portion 23 and the drainage portion 21 are arranged around the edge of the water injection port 12. When water in the water injection cavity 11 splashes onto the first connecting portion 22, the second connecting portion 23 or the drainage portion 21 near the water injection port 12, the water can flow into the water injection cavity 11 through any of them.

[0069] More specifically, in some embodiments, the width of the water overflow prevention portion 20 corresponding to the connection side 32 is greater than the width of the water overflow prevention portion 20 corresponding to the opening side 31 .

[0070] During the water filling process, the flip cover 30 is in an open state, and some water droplets may adhere to the surface of the flip cover 30 facing the box body 10 during this process. These water droplets are all gathered on the connection side 32 of the flip cover 30 under the action of gravity, and the amount of water gathered is greater than the amount of water on the open side 31 of the flip cover 30. Therefore, the anti-overflow part 20 is provided on the connection side 32, so that the anti-overflow part 20 can be effectively used to collect and discharge the water droplets flowing in from the surface of the flip cover 30, and the probability of water accumulation on the connection side 32 is reduced.

[0071] like Figure 5 As shown, in some embodiments, the box body 10 is also provided with a water outlet 13, and the water outlet 13 is connected to the water injection chamber 11; the water tank assembly 100 also includes a base 40, and the base 40 is provided on a side of the box body 10 where the water outlet 13 is provided, and the water storage chamber 41 of the base 40 is connected to the water injection chamber 11 through the water outlet 13, and an atomization part for atomizing the liquid is provided in the water storage chamber 41.

[0072] The water in the water injection chamber 11 can flow to the water storage chamber 41 of the base 40 through the water outlet 13, and then flow to the atomization part in the water storage chamber 41, and the atomization part can atomize the water.

[0073] like Figure 6As shown, in some embodiments, a floating assembly 42 is provided in the water storage chamber 41, and the floating assembly 42 can switch between a blocking state of blocking the water outlet 13 and a connecting state of connecting the water outlet 13. When in the blocking state, the amount of water in the water storage chamber 41 is greater than a preset amount of water; when in the connecting state, the amount of water in the water storage chamber 41 is less than the preset amount of water.

[0074] In this way, the floating component 42 is controlled by the amount of water in the water storage chamber 41, so that the floating component 42 is used to cover or expose the water outlet 13, which can reduce the probability of water originally flowing into the water storage chamber 41 overflowing from the water storage chamber 41 into the water injection chamber 11, and the water outlet 13 can be automatically opened and closed.

[0075] Specifically, Figure 7 As shown, in some embodiments, the floating assembly 42 includes a float plate 421, a mounting portion 422 and a valve body. One end of the mounting portion 422 is detachably mounted in the water storage chamber 41, and the other end is connected to the float plate 421. The float plate 421 and the valve body are movably connected. When the float plate 421 floats up, the valve body is closed. When the float plate 421 sinks, the valve body is opened and connected to the water outlet 13.

[0076] Assuming that the initial water volume in the water storage chamber 41 is 0, water is injected into the water injection chamber 11, and the injected water can flow into the water storage chamber 41 from the water outlet 13 of the water injection chamber 11. When the water volume in the water storage chamber 41 gradually increases, the float 421 gradually floats up under the action of buoyancy. When the water volume in the water storage chamber 41 reaches the preset water volume, the float 421 can lift up the valve body, and the valve body is closed. At this time, the water in the water injection chamber 11 no longer flows into the water storage chamber 41 through the water outlet 13.

[0077] When the amount of water in the water storage volume gradually decreases, the buoyancy of the floating plate 421 also decreases, the floating plate 421 gradually sinks, and the floating plate 421 no longer lifts the valve body, and the valve body opens. The water in the water injection chamber 11 can flow into the water storage chamber 41 through the water outlet 13. This arrangement simplifies the working principle of the floating assembly 42 and reduces the difficulty of preparing the floating assembly 42.

[0078] More specifically, if Figure 8 As shown, in some embodiments, the float assembly 42 further includes a filter 423 , which is disposed on the periphery of the valve body and located in the water injection chamber 11 .

[0079] When the water in the water injection chamber 11 passes through the water outlet 13 , it needs to first flow through the filter element 423 and be filtered by the filter element 423 , so as to improve the quality of the water flowing into the water storage chamber 41 .

[0080] See also Figure 6 and Fig. 9In some embodiments, the atomizing part is provided with a through hole 43, and a mist collecting cover 411 is further provided in the water storage chamber 41, and the mist collecting cover 411 covers the through hole 43. The mist collecting cover 411 can collect harmful gases generated by the atomizing part during the atomization process, and reduce the probability of the harmful gases flowing out of the base 40 through the through hole 43 and toward the outside.

[0081] like Fig.10 and Fig.11 As shown, in some embodiments, the water tank assembly 100 further includes a sealing cover 50 , which is disposed between the base 40 and the tank body 10 , and the sealing cover 50 is provided with an opening, which is connected to the water outlet 13 .

[0082] The shape of the opening is similar to that of the water outlet 13, and the surrounding edge of the sealing cover 50 can be clamped on the body 300 of the air supply device 1000, and the positioning groove of the sealing cover 50 can be clamped with the positioning rib on the body 300. When the sealing cover 50 and the body 300 are assembled together, the bolt column of the body 300 can be aligned with the bolt hole of the base 40, and then the surrounding edge of the body 300 and the limiting groove of the base 40 can be clamped, and then the body 300 and the base 40 can be fixed together by bolts, and finally the clamping part of the sealing cover 50 and the positioning rib on the base 40 are connected.

[0083] In this way, the sealing cover 50, the body 300 and the base 40 are connected together. The sealing cover 50 can visually block some parts of the base 40, beautifying the appearance of the water tank assembly 100.

[0084] Also, see Fig.12 The embodiment of the present application also provides an air supply device 1000. The air supply device 1000 includes an air supply member 200, a body 300, and a water tank assembly 100 in any of the above embodiments, wherein one end of the body 300 is connected to the air supply member 200, and the other end is connected to the water tank assembly 100. For the relevant contents of the water tank assembly 100, please refer to the above description.
