Description

Technical Field

[0001] The utility model belongs to the technical field of water treatment equipment, and in particular relates to a direct drinking water device for a residential area. Background Art

[0002] Direct drinking water, as a high-quality source of drinking water in cities, has become a ubiquitous part of urban development. It not only provides residents with a convenient and healthy way to drink water, but long-term consumption also significantly improves physiological functions, enhances physical health, and enhances overall quality of life. As living standards continue to rise, the demand for healthy drinking water is also growing. Consequently, direct drinking water supply equipment has been widely installed in residential communities, hotels, schools, office buildings, and other public places, providing the convenience of instant drinking water. This equipment eliminates the need for waiting and delivers water quickly, greatly facilitating people's lives while also improving the safety and health of drinking water. Based on these development prospects, our company is actively promoting the development of its direct drinking water business, cultivating new economic growth points. To further strengthen China Power Construction's strategic focus on building a new "water" business, we have formulated guidelines for the development of this business and are actively promoting related business initiatives.

[0003] At present, most of the drinking water in cities is directly connected to the tap water in residents' homes. Residents selectively install small filtering devices to filter the tap water according to their needs, and finally obtain pure direct drinking water. This method cannot achieve the widespread popularization of direct drinking water. Furthermore, there is also a small part that connects large filtering devices to the pipes where the tap water is connected to residents' homes to filter the tap water to obtain direct drinking water, and then connects the direct drinking water to residents' homes for direct use by residents. In actual use, the tap water passes through the inside of the filtering device to achieve filtering treatment, but with continued use, the water flow performance of the filtering device gradually decreases, causing the water inlet flow rate to be greater than the water outlet flow rate, so that unfiltered tap water will gather at the front end of the filter component, which will cause the pressure in the container to increase. When the pressure is too high, the gathered unfiltered water will bring the risk of overload operation to the filter component, which will lead to a shorter service life of the filter component. Utility Model Content

[0004] In view of the above-mentioned problems, the purpose of the present invention is to provide a community direct drinking water equipment that can effectively avoid the risk of overload operation of the filter component.

[0005] The technical solution of the utility model is: a community direct drinking water device, comprising a first tank body, a first filter assembly provided inside the first tank body, the first filter assembly being used to filter the tap water entering the first tank body, and characterized in that it also comprises:

[0006] The second tank body is provided with a partition plate inside, the partition plate divides the second tank body into a pressure-dividing chamber and a pressure-boosting chamber; the pressure-dividing chamber and the pressure-boosting chamber are connected through a pipeline assembly;

[0007] The second filter assembly includes two first filter elements, which are respectively disposed in the pressure-dividing chamber and the pressure-boosting chamber in a one-to-one correspondence, and are used to filter the tap water entering the pressure-dividing chamber and the pressure-boosting chamber respectively;

[0008] A pressure dividing pipe is used to connect the first tank body and the pressure dividing chamber, and the pressure dividing pipe is used to introduce the tap water in the first tank body that has not been processed by the first filter assembly into the pressure dividing chamber; and

[0009] A boosting pipe is used to connect the boosting chamber and the first tank body, and the boosting pipe is used to introduce the water in the boosting chamber into the water outlet position in the first tank body;

[0010] The first tank body is provided with a pressure measuring assembly, which is used to detect the pressure of the tap water in the first tank body that has not been filtered and processed by the first filter assembly.

[0011] Furthermore, the pipeline assembly includes:

[0012] a first connecting pipe, one end of which is connected to the pressure-dividing chamber, and the other end of which is connected to the water inlet side of the first valve;

[0013] a second connecting pipe, one end of which is connected to the water outlet side of the first valve, and the other end of which is connected to the water inlet side of the second valve;

[0014] The third connecting pipe has one end connected to the water outlet side of the second valve and the other end connected to the pressurizing chamber.

[0015] Furthermore, a first solenoid valve is provided on the pressure dividing tube.

[0016] Furthermore, a second solenoid valve is provided on the boost pipe.

[0017] Furthermore, the first filter assembly includes:

[0018] A sealing disk is disposed inside the first tank body and is provided with a through hole. The sealing disk divides the interior of the first tank body into a first filter chamber and a second filter chamber, wherein the first filter chamber and the second filter chamber are connected through the through hole. A water inlet pipe is provided on the first filter chamber, and a water outlet pipe is provided on the second filter chamber.

[0019] A connecting pipe is provided on the sealing disk and is located inside the first filter cavity, and one end of the connecting pipe is connected to the through hole;

[0020] A second filter element is embedded in the other end opening of the connecting pipe;

[0021] The filter disc is arranged in the second filter cavity and located between the sealing disc and the water outlet pipe.

[0022] Furthermore, there are multiple through holes, connecting pipes, and second filter elements, and they correspond one to one.

[0023] Furthermore, the first filter assembly further includes a grille, which is arranged in the first filter cavity and located at the water inlet of the water inlet pipe, and the end of the second filter element away from the connecting pipe is arranged on the grille.

[0024] Furthermore, the pressure measuring assembly includes:

[0025] a detection tube, disposed on the outer wall of the first filter cavity, the detection tube being in communication with the interior of the first filter cavity;

[0026] The hydraulic pressure gauge is arranged on the detection pipe and is communicated with the detection pipe.

[0027] Working method of the utility model:

[0028] In actual use, a large amount of tap water can enter the first tank through the water inlet pipe. The tap water first passes through the grille for coarse filtration, and then enters the cavity between the grille and the sealing disk. At this time, the tap water is restricted by the first filter component and cannot flow directly. It can only pass through the second filter element and then enter the connecting pipe, and then flow into the other side of the sealing disk. After a second filtration through the filter disk, it can be discharged from the first tank through the water outlet pipe and then supplied to residents for direct drinking water. Among them, since the second filter element closes one end of the connecting pipe, the tap water can only flow from the outside to the inside along the radial direction of the second filter element, and then flow into the connecting pipe. Since there are a number of flow pipes and second filter elements, the tap water is filtered in batches.

[0029] With long-term use, the fluidity of the first filter assembly decreases, and tap water continues to enter the first tank body. Tap water gathers in front of the first filter assembly, increasing the water pressure in the first filter chamber. The hydraulic gauge continuously detects the water pressure in the first filter chamber. When the water pressure inside the first tank body exceeds the preset value, it is only necessary to open the first solenoid valve, the second solenoid valve, the first valve, and the second valve, so that the tap water that has not been processed by the first filter assembly after coarse filtration flows into the pressure-dividing chamber, passes through the first filter element for the first filtration, and then enters the boosting chamber through the first connecting pipe, the second connecting pipe, and the third connecting pipe in sequence. After the tap water passes through the first filter element for the second filtration, it enters the second filter chamber through the boosting pipe, and then supplies residents with direct drinking water. This can effectively divide the pressure in the first filter chamber and replenish the pressure in the second filter chamber.

[0030] Compared with the prior art, the beneficial effect of the present invention is that: the present invention forms a buffer chamber for draining the tank body by adding a tank body on the basis of the existing tank body, which can effectively adjust the water pressure inside the existing tank body after the water flow performance of the filter device is reduced, effectively avoiding the large impact on the filter component caused by excessive water pressure, effectively avoiding the risk of overload operation of the filter component, and increasing the service life of the filter component.

[0053] The working principle of the above embodiment is:

[0054] During actual application, a large amount of tap water can enter the first tank body 1 through the water inlet pipe 110. The tap water first passes through the grille 25 for coarse filtration, and then enters the cavity between the grille 25 and the sealing disk 21. At this time, the tap water is restricted by the first filter component 2 and cannot circulate directly. It can only pass through the second filter element 23 and then enter the connecting pipe 22, and then flow into the other side of the sealing disk 21. After passing through the filter disk 24 for secondary filtration, it can be discharged from the first tank body 1 from the water outlet pipe 120, and then supplied to residents for direct drinking water. Among them, since the second filter element 23 closes one end of the connecting pipe 22, the tap water can only flow from the outside to the inside along the radial direction of the second filter element 23, and then flow into the connecting pipe 22. Since there are a plurality of flow pipes 22 and second filter elements 23, the tap water is filtered in batches.

[0055] With long-term use, the fluidity of the first filter assembly 2 decreases, and tap water continues to enter the first tank body 1. Tap water gathers in front of the first filter assembly 2, causing the water pressure in the first filter chamber 11 to increase. The hydraulic gauge 102 continuously detects the water pressure in the first filter chamber 11. When the water pressure inside the first tank body 1 exceeds the preset value, it is only necessary to open the first solenoid valve 50, the second solenoid valve 60, the first valve 333, and the second valve 335, so that the tap water that has not been processed by the first filter assembly 2 after coarse filtration flows into the pressure-dividing chamber 31, passes through the first filter element for the first filtration, and then enters the boosting chamber 32 in the order of the first connecting pipe 331, the second connecting pipe 332, and the third connecting pipe 333. After the second filtration by the first filter element, it enters the second filter chamber 12 through the boosting pipe 6, and then supplies residents with direct drinking water. This can effectively divide the pressure in the first filter chamber 11 and replenish the pressure in the second filter chamber 12.
