[0052] As Figures 1-4 shown, the embodiment discloses a pressure water storage barrel, which comprises a barrel body 1 and a water bag 2, the barrel body 1 is provided with a containing cavity 11, and the barrel body 1 is also provided with a first water inlet and outlet 12 in communication with the containing cavity 11; the water bag 2 is located in the containing cavity 11, and a space between the barrel body 1 and the water bag 2 forms a water storage cavity (the remaining part of the containing cavity 11 except the part occupied by the water bag 2); the barrel body 1 is also provided with a second water inlet and outlet 13 in communication with the inner cavity of the water bag 2, and the second water inlet and outlet 13 is used for being in communication with an external tap water pipe; the water bag 2 can be deformed by water injection or water discharge to change the size of the water storage cavity. The pressure water storage barrel is used for storing purified water.

[0053] As Figures 1-4 shown, in the embodiment, the pressure water storage barrel comprises a barrel body 1 and a water bag 2, the water bag 2 is arranged in the inside of the barrel body 1, and a space between the barrel body 1 and the water bag 2 forms a water storage cavity; by communicating the water bag 2 with the external tap water pipe, the water bag 2 is deformed according to pressure change to replace the traditional air bag, so that the problem of air leakage of the air bag cavity does not exist, and the detection device for detecting air pressure and the inflating device do not need to be arranged, the structure of the pressure water storage barrel is simplified, and the size of the water outlet flow of the pressure water storage barrel can be set according to the water pressure of the tap water pipe, the water outlet flow is conveniently adjusted, the water outlet flow is constant, and user experience is improved.

[0054] As Figures 1-4 shown, when the purified water flows into the water storage cavity of the barrel body 1 from the first water inlet and outlet 12, as more and more purified water flows in, the water pressure of the water storage cavity is greater than the water pressure in the water bag 2, at this time, the purified water in the water storage cavity will press the water bag 2, and the tap water in the water bag 2 will flow out from the second water inlet and outlet 13 at this time, and more purified water can be stored in the water storage cavity. When the user uses the purified water to open the valve on the first water inlet and outlet 12, the water pressure of the water storage cavity is less than the water pressure in the water bag 2, the tap water will enter the water bag 2 from the second water inlet and outlet, the water bag 2 begins to expand due to the water pressure, and the purified water is squeezed out of the water storage cavity, which is convenient for the user to use the purified water.

[0055] As Figures 2-4 shown, in the embodiment, the water bag 2 is in a ring structure, the bottom of the barrel body 1 is provided with an annular flange 14 protruding upwards, and one end of the water bag 2 is sleeved on the annular flange 14 and used for fixing the water bag 2.

[0056] As Figure 1 andFigure 2 As shown, in this embodiment, the pressure water storage tank also includes a germicidal lamp 3, which is installed on the tank body 1. The lamp tube 31 of the germicidal lamp 3 extends into the water storage cavity and is located in the middle of the annular structure. The germicidal lamp 3 is used to sterilize the water in the water storage cavity and prevent bacterial growth.

[0057] In another embodiment, the pressure water storage tank also includes a germicidal lamp, which is installed in the tank body and has its lamp tube extending into the water storage chamber. The germicidal lamp is used to sterilize the water in the water storage chamber and prevent bacterial growth.

[0058] like Figures 2-4 As shown, in this embodiment, the water bladder 2 includes a first ring structure 21 and a second ring structure 22. The first ring structure 21 and the second ring structure 22 are stacked and spaced apart. The first ring structure 21 and the second ring structure 22 are connected by a pipe 23, which facilitates the free flow of water between the periphery and the center of the water bladder 2, so as to facilitate sterilization by the germicidal lamp 3 and improve the sterilization effect. At the same time, it also facilitates the uniform deformation of the water bladder 2 and quickly squeezes the water in the water storage cavity.

[0059] like Figure 2 As shown, in this embodiment, a receiving cavity 141 is formed in the middle of the annular flange 14, and a rotatable impeller 4 is installed in the receiving cavity 141. A plurality of flow holes 142 are provided on the outer peripheral surface of the annular flange 14, connecting the receiving cavity 141 to the outer peripheral side of the annular flange 14, facilitating free water flow and improving the sterilization effect. During the deformation of the water bladder 2, water also flows through the flow holes 142. The water flow drives the impeller 4 to rotate, and the rotation of the impeller 4 further agitates the water in the tank, causing different parts of the water to flow through the sterilizing lamp, thereby improving the sterilization effect. Preferably, the flow holes are vertically arranged oblong holes.

[0060] In another embodiment, the pressure water storage tank also includes a rotatable impeller, which is mounted on the tank body 1 and located in the water storage chamber. The impeller rotates under the drive of water during the deformation of the water bladder, thereby fully agitating the water and causing different portions of the water to flow through the germicidal lamp, improving the sterilization effect.

[0061] like Figure 3 and Figure 4 As shown, in this embodiment, a water flow channel 24 extending radially is provided at one end of the water bladder 2 near the annular flange 14. The water flow channel 24 connects the middle part of the annular water bladder 2 with its periphery. Several water flow channels 24 are provided, evenly spaced along the circumferential direction of the water bladder 2. By providing the water flow channels 24, water can flow between the periphery and the middle part of the water bladder 2, driving the impeller 4 to rotate, thereby fully agitating the water. This allows different parts of the water to flow through the germicidal lamp 3, improving the sterilization effect.

[0062] likeFigure 2 As shown in the embodiment, the pressure water storage barrel further comprises a water outlet nozzle 5, which is installed on the second water inlet and outlet 13 and used to fix the upper end of the water bag 2 to the barrel body 1. The water outlet nozzle 5 is used to connect external pipelines for convenient and quick connection.

[0063] Preferably, the water bag 2 is made of a light-transmitting material, which facilitates the light of the sterilization lamp 3 to pass through the water bag 2 and improves the sterilization effect.

[0064] The embodiment also discloses a water purifier, which comprises the pressure water storage barrel as described above. When the purified water flows into the barrel body 1 from the first water inlet and outlet 12, as more and more purified water flows in, the water pressure in the water storage cavity is greater than that in the water bag 2, at which time the purified water in the water storage cavity will squeeze the water bag 2, and the tap water in the water bag 2 will flow out of the second water inlet and outlet 13 at this time. At the same time, when the purified water flows into the barrel body 1, the water on the side flows to the bottom of the water bag 2 through the water flow channel 24, at which time the impeller 4 will rotate. The impeller 4 rotates and agitates the water in the barrel body 1, so that all the water can have the opportunity to flow near the sterilization lamp 3, thereby improving the sterilization efficiency.

[0065] When the user needs to use the purified water, the water pressure in the water storage cavity is less than that in the water bag 2, the tap water will squeeze into the water bag 2 from the second water inlet and outlet 13, and the water bag 2 will begin to expand due to the water pressure and squeeze the purified water out of the water storage cavity. The water bag 2 will squeeze the purified water in the water storage cavity while expanding, and the purified water will flow to the impeller 4 through the flow-through hole 142 on the annular flange 14, thereby driving the impeller 4 to rotate. The impeller 4 rotates further to agitate the purified water in the barrel, thereby improving the sterilization effect.
