[0030] Referring to Figures 1 to 6 As shown, according to the embodiments of the present application, a water tank is provided, which comprises a tank body 10 and an elastic sealing member 20, wherein the tank body 10 is provided with a water storage cavity 11 and a water outlet 12, the elastic sealing member 20 is fixed to the tank body 10, the elastic sealing member 20 comprises a first water outlet channel 21, the first water outlet channel 21 is in communication with the water outlet 12 and the water storage cavity 11 respectively, the elastic sealing member 20 has at least a closed state in which the first water outlet channel 21 is closed due to the elastic deformation of the elastic sealing member 20 under the internal water pressure of the water storage cavity 11, and the elastic sealing member 20 also has a conducting state in which the first water outlet channel 21 is conducted due to the elastic deformation of the elastic sealing member 20 under the external force.

[0031] Further, the water outlet 12 is provided through the side wall of the tank body 10 and is in communication with the water storage cavity 11, and the water outlet 12 is spaced apart from the bottom of the water storage cavity 11 by a predetermined distance.

[0032] The embodiment fixes the elastic sealing member 20 at the water outlet 12 in the tank body 10 of the water tank, sets the first water outlet passage 21 of the elastic sealing member 20 to communicate with the water outlet 12 and the water storage cavity 11 respectively, and the elastic sealing member 20 has two states of being elastically deformed to close the first water outlet passage 21 under the water pressure in the water storage cavity 11 and being elastically deformed to open the first water outlet passage 21 under the external force. When the water tank is not assembled to the predetermined device, the water outlet 12 of the water tank is in the exposed state, and because the water outlet 12 is spaced apart from the bottom of the water storage cavity 11 by a predetermined distance, when the water level in the water storage cavity 11 is higher than the water level of the water outlet 12, the siphon phenomenon occurs to cause the water in the water storage cavity to flow out of the water outlet 12. At this time, the elastic sealing member 20 is only subjected to the water pressure in the tank body 10, and the elastic sealing member 20 is in the closed state, so that the water in the water tank does not overflow out of the water outlet 12 due to the siphon phenomenon, and the problem of water flowing out of the water tank when the water in the water tank is full is avoided. When the water tank is assembled to the predetermined device, the water inlet pipe on the predetermined device for matching the water outlet 12 of the water tank is directly inserted into the first water outlet passage 21 of the elastic sealing member 20 from the water outlet 12, and the elastic sealing member 20 is elastically deformed under the extrusion force of the water inlet pipe of the predetermined device to open the first water outlet passage 21, so that the water in the water storage cavity 11 can smoothly enter the predetermined device.

[0033] Further, the elastic sealing member 20 includes a boss portion 22, the first water outlet passage 21 is provided through the boss portion 22, and at least one inclined surface 221 is provided on the outer circumferential side of the boss portion 22. The inclined surface 221 is elastically deformed under the water pressure in the tank body 10 to close the first water outlet passage 21.

[0034] Further, the port 211 of the first water outlet passage 21 near the water storage cavity 11 is provided in a straight line shape, the inclined surfaces 221 are provided on the opposite sides of the boss portion 22, the extension line of the straight line-shaped port 211 is parallel to the inclined surfaces 221, and the distance between the inclined surfaces 221 on the opposite sides of the boss portion 22 gradually increases along the water outlet direction of the first water outlet passage 21 (the flow direction of the water from the second water outlet passage 12 to the first water outlet passage 21).

[0035] In this embodiment, due to the presence of the inclined surface 221, the water pressure on the inclined surface 221 will generate a component force directed to the center of the boss portion 22. As the water pressure increases, this component force will cause the boss portion 22 to elastically deform. During the elastic deformation, the first water outlet channel 21 provided through the boss portion 22 will gradually close. Because the side port 211 of the first water outlet channel 21 close to the water storage cavity 11 is provided in a straight line shape, and its extension line (i.e. the length direction of the straight line type port 211 in the natural state) is parallel to the inclined surface 221, when the inclined surface 221 deforms towards the center under the action of water pressure, it will directly press the port part of the first water outlet channel 21, causing it to close. This structural design can effectively prevent water overflow caused by siphon phenomenon. The setting of the inclined surface 221 can make the outer periphery of the boss portion 22 subjected to greater water pressure, so that the elastic sealing piece 20 is better in the closed state, improving the effect of using the elastic sealing piece 20 to avoid siphon phenomenon of the water tank.

[0036] Further, the elastic sealing piece 20 further comprises a positioning portion 23, and the boss portion 22 is arranged on the first side surface 231 of the positioning portion 23; the inner wall surface of the tank body 10 is provided with a mounting table 13, and the water outlet 12 is provided through the mounting table 13, and the mounting table 13 is provided with a positioning groove 131 matched with the positioning portion 23.

[0037] In this embodiment, the mounting table 13 through which the water outlet is provided is arranged on the inner wall surface of the tank body 10, and the positioning groove 131 matched with the positioning portion 23 of the elastic sealing piece 20 is arranged on the mounting table 13, so that the elastic sealing piece 20 can be better fixed on the water outlet 12, and the positioning groove 131 can prevent the elastic sealing piece 20 from being displaced when the water tank vibrates due to external factors, thereby improving the water leakage protection effect of the water tank and avoiding the blockage of the water outlet 12 by the elastic sealing piece 20.

[0038] Further, at least one annular protrusion 233 is arranged on the first side surface 231 and the second side surface 232 opposite to the first side surface 231 of the positioning portion 23, and the annular protrusion 233 is arranged around the outer periphery side of the first water outlet channel 21, and when there are a plurality of annular protrusions 233, the plurality of annular protrusions 233 are nested. Figure 4 And Figure 5 As shown in the first side surface 231 and the second side surface 232 of the positioning portion 23 are provided with two annular protrusions 233, and the two annular protrusions 233 are nested, that is, on the first side surface 231 or the second side surface 232, one annular protrusion 233 completely surrounds the other annular protrusion 233 on the surface (i.e. the first side surface 231 or the second side surface 232).

[0039] In the embodiment, the annular protrusions are arranged on the first side surface 231 (the side surface of the positioning portion 23 away from the mounting platform 13) and the second side surface 232 (the side surface of the positioning portion 23 close to the mounting platform 13) of the positioning portion 23, respectively. The annular protrusions can form a better sealing effect between the elastic sealing member 20 and the tank body 10, and prevent water leakage at the assembly of the elastic sealing member 20. In the embodiment, the annular protrusions 233 are arranged on the first side surface 231 or the second side surface 232 in multiple numbers, which can improve the sealing effect.

[0040] Further, the water tank further comprises a positioning frame 30, the positioning frame 30 is provided with a mounting cavity 31 and a second water outlet channel 32, the second water outlet channel 32 is in communication with the mounting cavity 31 and the water storage cavity 11, respectively, the positioning frame 30 is fixed to the tank body 10 and abuts against the first side surface 231 of the positioning portion 23, and the boss portion 22 is located in the mounting cavity 31.

[0041] That is, the positioning frame 30 is fixed to the tank body 10 and abuts against the first side surface 231 of the positioning portion 23, the positioning frame 30 can abut the elastic sealing member 20 against the positioning groove 131 of the mounting platform 13, cooperate with the annular protrusions 233 on the elastic sealing member 20, the annular protrusions 233 are deformed under the abutting force of the positioning frame 30 to realize the sealing between the first side surface 231 of the positioning portion 23 of the elastic sealing member 20 and the positioning frame 30, and realize the sealing between the second side surface 232 and the positioning groove 131. The second water outlet channel 32 of the positioning frame 30 is in communication with the mounting cavity 31 and the water storage cavity 11, respectively, and the boss portion 22 of the elastic sealing member 20 is located in the mounting cavity 31, which can not only realize the abutting sealing of the elastic sealing member 20, but also make the water in the water storage cavity 11 enter the first water outlet channel 21 of the elastic sealing member 20 through the positioning frame 30, thereby improving the reliability of the water tank.

[0042] Further, the positioning frame 30 is provided with a positioning groove 33 close to the mounting platform 13, and the top of the mounting platform 13 is embedded in the positioning groove 33. The positioning groove 33 can make the cooperation between the positioning frame 30, the mounting platform 13 and the elastic sealing member 20 more closely, thereby improving the water leakage prevention effect of the water tank.

[0043] Further, the water tank further comprises a water outlet pipe 40, the positioning frame 30 is provided with a limiting hole 34, and the water outlet pipe 40 is communicated with the second water outlet channel 32 after penetrating through the limiting hole 34. That is, the water storage cavity 11 and the second water outlet channel 32 of the positioning frame 30 are communicated through the water outlet pipe 40, and the water outlet pipe 40 can avoid that a large water pressure is concentrated on the second water outlet channel 32 of the positioning frame 30, thereby improving the safety of the water tank. By arranging the limiting hole 34 on the positioning frame 30 and communicating the water outlet pipe 40 with the second water outlet channel 32 after penetrating through the limiting hole 34, the water outlet pipe 40 can be better fixed, the movement of the water outlet pipe 40 in the water storage cavity 11 is prevented, and even the water outlet pipe 40 is prevented from falling off, thereby improving the reliability of the water tank.

[0044] Further, when the elastic sealing piece 20 is in a natural state (the elastic sealing piece 20 is not subjected to other external pressure except for the internal water pressure of the water storage cavity 11), the cross-sectional area of the first water outlet channel 21 gradually increases along the water outlet direction of the first water outlet channel 21. In the case that the flow rate is constant, the water flow speed is reduced with the increase of the cross-sectional area. When the water tank is normally drained, the structure can slow down the speed of water flowing out of the first water outlet channel 21. And when the water tank is assembled to a predetermined device, the first water outlet channel 21 with the gradually increasing cross-sectional area (the cross-sectional area of the first water outlet channel 21 perpendicular to the water outlet direction) can be better connected with the water inlet pipe of the predetermined device, and can adapt to different models of water inlet pipes, thereby improving the reliability and adaptability of the water tank.

[0045] Further, the water tank of the embodiment further comprises a connecting assembly 50, and the positioning frame 30 is fixedly connected with the tank body 10 through the connecting assembly 50.

[0047] In the embodiment, the water inlet pipe of the base station is inserted into the first water outlet channel 21 of the elastic sealing member 20, because the cross-sectional area of the first water outlet channel 21 gradually increases in the water outlet direction, that is, the cross-sectional area of the first water outlet channel 21 gradually decreases in the direction of the linear port 211 close to the elastic sealing member 20, the water inlet pipe of the base station can extrude the elastic sealing member 20 to open the linear port 211, so that the elastic sealing member 20 is switched from the sealing state to the conducting state, and the water in the water storage cavity 11 of the water tank can smoothly enter the base station, so that the water tank can smoothly outlet water when in use and can prevent siphon overflow when not in use, thereby improving the reliability and safety of the water tank.
