[0047] As Figures 1-3As shown, the embodiment provides a pressure barrel 100, which comprises a shell 1, a diaphragm 2 and a germicidal lamp 3, the shell 1 is internally formed with a containing cavity, the shell 1 is also provided with a water inlet and outlet 103, the diaphragm 2 is fixed to the cavity wall of the containing cavity, the diaphragm 2 divides the containing cavity into a first chamber 101 and a second chamber 102 which are not communicated with each other, the first chamber 101 is communicated with the water inlet and outlet 103, the diaphragm 2 is elastic, the diaphragm 2 can be deformed under the action of water pressure to change the volume of the first chamber 101 and the second chamber 102, the germicidal lamp 3 is fixed to one side of the diaphragm 2 facing the first chamber 101, and the diaphragm 2 can drive the germicidal lamp 3 to move. By arranging the germicidal lamp 3 in the pressure barrel 100 and fixing the germicidal lamp 3 to one side of the diaphragm 2 facing the first chamber 101, the germicidal lamp 3 can sterilize the water in the first chamber 101 at close range. At the same time, during the process of filling and draining water through the water inlet and outlet 103, the pressure in the pressure barrel 100 will change, which will cause the diaphragm 2 to deform. When the diaphragm 2 deforms under the action of water pressure, the diaphragm 2 can drive the germicidal lamp 3 to move, and the germicidal lamp 3 can always keep close distance with the water under the driving of the diaphragm 2, thereby improving the sterilization effect. By fixing the germicidal lamp 3 on the diaphragm 2 and driving the germicidal lamp 3 to move through the deformation of the diaphragm 2, the movement of the germicidal lamp 3 can be realized without additional driving mechanism in the pressure barrel 100, which simplifies the structure of the pressure barrel 100 and improves the reliability of the pressure barrel 100.

[0048] At the same time, the diaphragm 2 drives the water in the first chamber 101 to flow during the deformation process, so that the water in the first chamber 101 forms running water, which can flow at close range through the germicidal lamp 3, thereby improving the sterilization effect.

[0049] The germicidal lamp 3 can be powered by existing power supply methods, such as battery or dry cell power supply, external circuit power supply and the like. When battery charging is adopted, the charging can be performed by existing charging methods, such as wireless charging, and the battery can be replaced when it is exhausted. Details are not described herein.

[0050] In this embodiment, the germicidal lamp 3 is charged by external power cord. The germicidal lamp 3 comprises a germicidal lamp tube 31, one end of the germicidal lamp tube 31 is fixed to the diaphragm 2, the shell 1 is provided with a avoiding hole, when the diaphragm 2 deforms towards the first chamber 101, the other end of the germicidal lamp tube 31 can extend out of the containing cavity through the avoiding hole, and the germicidal lamp tube 31 is sealed between the avoiding hole and the circumferential side. By arranging the lamp tube in the germicidal lamp 3 and setting the avoiding hole on the shell 1, one end of the lamp tube is fixed to the diaphragm 2, and the other end can extend out of the containing cavity through the avoiding hole, so that the germicidal lamp 3 can be externally connected to the power cord, which is convenient for power supply of the germicidal lamp 3.

[0051] Specifically, the germicidal lamp 3 is fixed at the center of the diaphragm 2. When the diaphragm 2 deforms, the deformation at the center of the diaphragm 2 is the greatest. Therefore, fixing the germicidal lamp 3 at the center of the diaphragm 2 can expand the range of movement of the germicidal lamp 3 and further improve the sterilization effect.

[0052] Of course, in other embodiments, the germicidal lamp 3 can also be fixed at other positions of the diaphragm 2, as long as the deformation of the diaphragm 2 can drive the germicidal lamp 3 to move, which will not be elaborated here.

[0053] In this embodiment, the receiving cavity is capsule-shaped, with the center of the diaphragm 2 and the axis of the germicidal lamp 3 both coinciding with the axis of the receiving cavity. Along the axial direction of the receiving cavity, the length of the germicidal lamp tube 31 is greater than or equal to the length of the receiving cavity. By setting the shape of the receiving cavity as a capsule, and combining it with the tubular structure of the germicidal lamp tube 31, and aligning the germicidal lamp tube 31 with the axis of the receiving cavity, the irradiation of the germicidal lamp 3 within the receiving cavity can be made more uniform. Simultaneously, by setting the length of the germicidal lamp 3 to be greater than or equal to the length of the receiving cavity, when the first chamber 101 is filled with water, the irradiation range of the germicidal lamp tube 31 can also uniformly cover the first chamber 101 along the axial direction of the receiving cavity, further improving the sterilization effect.

[0054] Of course, in other embodiments, the germicidal lamp tube 31 may also be inclined relative to the axis of the receiving cavity, and the shape of the receiving cavity is not limited to this, which will not be described in detail here.

[0055] Specifically, in this embodiment, the pressure tank 100 further includes a switching valve 4, which, along with the inlet / outlet 103 and the first chamber 101, are sequentially connected. A clearance hole is formed on the switching valve 4. By providing the switching valve 4, the sealing performance of the pressure tank 100 can be improved, preventing leakage. Simultaneously, by placing the clearance hole at the switching valve 4, too many holes are avoided on the housing 1 of the pressure tank 100, thus improving the reliability of the pressure tank 100.

[0056] Specifically, such as Figure 3As shown, the switch valve 4 comprises a screwing part 41, a first sealing plate 42 and a second sealing plate 43. The first sealing plate 42 and the second sealing plate 43 abut in the water inlet direction. The first sealing plate 42 and the second sealing plate 43 each have a through hole extending in the water inlet direction. The first sealing plate 42 is fixed with the screwing part 41, and the second sealing plate 43 is fixed with the shell 1. The screwing part 41 is rotatable relative to the shell 1. When the screwing part 41 is rotated to drive the first sealing plate 42 to rotate to the position where the through holes on the first sealing plate 42 and the second sealing plate 43 are aligned, the water inlet and outlet port 103 and the first chamber 101 are communicated through the through holes, and water can flow into or out of the first chamber 101, so as to realize water inlet or outlet. When the screwing part 41 is rotated to drive the first sealing plate 42 to rotate to the position where the through holes on the first sealing plate 42 and the second sealing plate 43 are misaligned, the switch valve 4 is closed, and at this time the pressure barrel 100 cannot inlet or outlet water.

[0057] In the embodiment, the pressure barrel 100 further has a guide structure 5 fixed on the pressure barrel 100. The guide structure 5 has a guide hole extending along the extension direction of the sterilization lamp tube 31. The sterilization lamp tube 31 is arranged in the guide hole. The guide structure 5 is used to guide the sterilization lamp tube 31 to move along the axial direction of the sterilization lamp tube 31.

[0058] Meanwhile, in the embodiment, the sterilization lamp 3 and the diaphragm 2 are detachably connected. Specifically, the sterilization lamp 3 comprises the sterilization lamp tube 31 and a connecting part 32. The connecting part 32 is fixed on the diaphragm 2, and the connecting part 32 is connected with the sterilization lamp tube 31 through detachable fasteners. By arranging the sterilization lamp 3 to be detachably connected with the diaphragm 2, the sterilization lamp 3 can be replaced when it is damaged.

[0059] Of course, in other embodiments, the sterilization lamp 3 can also be fixed on the diaphragm 2 in a non-detachable manner, which will not be described herein.

[0060] In the embodiment, the shell comprises an upper cover 11 and a lower cover 12 arranged separately. The upper cover 11 and the lower cover 12 are sealingly connected, and the diaphragm 2 is fixed on the upper cover 11. By arranging the shell to comprise the separately arranged upper cover 11 and lower cover 12, on the one hand, the manufacturing of the pressure barrel 100 is facilitated, and on the other hand, the diaphragm 2 and the sterilization lamp 3 are facilitated to be replaced.

[0061] In the embodiment, the diaphragm 2 is made of rubber. By arranging the diaphragm 2 to be made of rubber, the rubber diaphragm 2 has good durability and reliability, and does not need to be replaced frequently, thereby reducing the maintenance cost and prolonging the service life of the diaphragm 2.

[0062] Of course, in other embodiments, other materials with elasticity and good sealing performance in the prior art can also be used to manufacture the diaphragm 2, which will not be described herein.

[0063] In the embodiment, the shell further has a gas inlet 104 communicating with the second chamber 102. By arranging the gas inlet 104 communicating with the second chamber 102 on the shell, the second chamber 102 can be filled with gas through the gas inlet 104, thereby improving the stability of the water pressure of the pressure barrel 100.

[0064] The embodiment also provides a sterile water supply system including the pressure barrel 100 as described above. By arranging the pressure barrel 100 as described above in the sterile water supply system, the sterilization effect of the pressure barrel 100 is better, so that the total number of colonies of the sterile water supply system is lower and can reach the direct drinking water standard.

[0065] Specifically, in the embodiment, the sterile water supply system includes a purification module and a heating module, and the purification module is composed of a pre-filter, a clean water electromagnetic valve, a pump, a membrane (a reverse osmosis membrane, a nanofiltration membrane, an ultrafiltration membrane, etc.), a check valve, a post-filter, an ultraviolet sterilization lamp 3, a high-voltage switch, the pressure barrel 100, a manual ball valve, a flushing electromagnetic valve, a waste water electromagnetic valve, a drainage electromagnetic valve, a pipeline, an electric control system, etc.

[0066] When water is produced, the water inlet electromagnetic valve is opened, tap water is preliminarily filtered through the pre-filter, is pressurized by the water pump to enter the membrane element, and the purified water (sterile water) is stored in the pressure barrel 100 through the check valve. The ultraviolet sterilization lamp 3 built in the pressure barrel 100 sterilizes the stored water, the post-filter further purifies the water, and the water is used by the user through the normal temperature water outlet electromagnetic valve after being sterilized by the flow type ultraviolet sterilization, or is heated in the hot water tank.

[0067] The heating module is composed of a hot water tank water inlet electromagnetic valve, a check valve, a step type heating water tank (a water inlet, an electric heating pipe, etc.), a hot water tank water outlet electromagnetic valve, a pipeline, an electric control system, etc.

[0068] When the hot water tank needs to be replenished with water, the hot water tank water inlet electromagnetic valve is opened, and the water stored in the pressure barrel 100 enters the hot water tank to replenish the hot water tank.

[0069] Specifically, the sterile water supply system has an internal pipeline purification function, and the specific process is as follows: the electric control system detects that the water pump has not worked for a certain time (such as 2 hours), the water inlet electromagnetic valve, the normal temperature water outlet electromagnetic valve, the hot water tank water inlet electromagnetic valve, the drainage electromagnetic valve, and the waste water electromagnetic valve are closed, the water pump and the flushing electromagnetic valve are opened, and the water in the internal closed pipeline formed by the valves and the pressure barrel 100 is circulated for a certain time (such as 5 minutes) to purify the water through the membrane. After purification, the water in the pipeline is ensured to be sterile, and the bacteria breeding in the waterway are physically filtered out by the membrane element (a reverse osmosis membrane, a nanofiltration membrane, an ultrafiltration membrane, etc.).

[0070] The related time parameters can be set by the user.

[0071] At the same time, the sterile water supply system also has a dead water design, specifically by the following scheme is realized:
