Technical Field
[0001] The utility model relates to the technical field of water storage of drinking water supply equipment, in particular to a vacuum water storage system. Background Art
[0002] In existing drinking water supply equipment, a water tank is generally provided. An exhaust hole is provided on the water tank so that the gas in the water tank is discharged to the outside when storing water in the water tank, and outside air enters the water tank when pumping water from the water tank. Since this structure has the exhaust hole communicating with the outside and outside air will enter the water tank as the water level in the water tank drops when pumping water from the water tank, bacteria, dust, etc. in the external air are likely to enter the water tank with the gas, resulting in pollution of the water quality in the water tank.

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Embodiment, please refer to Figure 1 , the present application provides a vacuum water storage system, including a water tank 1, a water inlet 1-1 and a drain port 1-2 are provided on the water tank, a metering suction and pressure valve 2 is connected to the water inlet, and a diaphragm water pump 3 is connected to the drain port. The metering suction and pressure valve can use existing structures, such as the structure of the metering suction and pressure valve with the application number 202110010836.X and the invention name of metering suction and pressure valve. Similarly, the diaphragm water pump can also use existing structures.
[0021] When the above-mentioned vacuum water storage system is in use, raw water is connected to the water inlet of the metering suction and pressure valve. The suction and discharge port of the metering suction and pressure valve is connected to the water inlet of the water tank. The drain port of the water tank is connected to the water inlet of the diaphragm water pump. The water outlet of the diaphragm water pump is used to supply drinking water. When the diaphragm water pump works, it starts to extract the air in the water tank, so that a negative pressure is formed in the water tank. At this time, the metering suction and pressure valve is activated, and raw water can enter the water tank through the metering suction and pressure valve. After the water tank is full, the diaphragm water pump and the metering suction and pressure valve stop working. At this time, the water tank is in a fully sealed state, and bacteria, dust, etc. in the external air are not easily introduced into the water tank along with the gas, so the water quality in the water tank is not easily polluted. When the diaphragm water pump extracts the water in the water tank for people to use, the metering suction and pressure valve is activated in time to replenish water to the water tank. In this way, the water tank is still in a fully sealed state during the process of replenishing water to the water tank.
[0022] As a preferred embodiment, refer to Figure 2 , an electric heating element is also installed in the water tank. In this embodiment, the electric heating element can use an electric heating tube 4. By setting the electric heating element, after the water tank is full, the electric heating element is controlled to work to heat the water in the water tank. The water outlet of the diaphragm water pump can provide hot water at a certain temperature for people. In order to prevent the volume expansion of the water after the electric heating element heats the water and cause potential safety hazards, a check valve 5 is also connected to the drain port. In this way, the check valve opens to relieve pressure after the water expands to a certain extent, ensuring the safe operation of the entire system.
[0023] As a preferred embodiment, refer to Figure 3 , a coil pipe 6 is fixed in the water tank. The coil pipe can use a stainless steel coil pipe. The water inlet is connected to the suction and discharge port of the metering suction and pressure valve. The drain port is connected to the water inlet of the diaphragm water pump. The water outlet of the diaphragm water pump is connected to a heating body. One end of the heating body that is not connected to the diaphragm water pump is connected to one end of the coil pipe. The other end of the coil pipe extends out of the water tank for supplying water to people. In this embodiment, the heating body is preferably an integrated heating body 7. The integrated heating body includes a heating body water inlet 7-1 and a heating body water outlet 7-2. The coil pipe is communicated with the integrated heating body water outlet, and the diaphragm water pump is communicated with the integrated heating body water inlet. The integrated heating body can use an existing structure. In this embodiment, the instant heating integrated heating body with the authorization announcement number of CN215637969U is used. When this structure is in use, the diaphragm water pump extracts the water in the water tank and then supplies the water to the heating body for heating. The heated water exchanges heat with the water in the water tank through the coil pipe circulation to obtain the heated low-temperature water, which is simply called cooled boiled water. Of course, the water in the water tank can also be heated by the electric heating element and then reheated by the heating body to quickly provide high-temperature water for people. It should be noted that when only cooled boiled water is provided, the electric heating element may not be installed in the water tank.
[0024] In the above embodiments, the metering suction and pressure valve may also be replaced with a negative pressure valve or a zero pressure valve.
