Therefore, household water purification devices are widely used in families as an effective means to ensure the cleanliness and safety of drinking water. There are a wide variety of household water purification devices on the market today, with different functions.
[0003] In the existing market of household water purification devices, although there are many products with different types and functions, many household water purification devices have a common problem, that is, consumable parts such as filter membranes and filter elements need to be replaced regularly. This not only increases the use cost, but also may bring inconvenience and trouble to users. Replacing the filter element not only requires additional costs, but also may require professional maintenance or adjustment, affecting the user experience.
[0004] Some improvements have been made to the existing devices, but there are still some problems in the water purification process. For example, the patent with the publication number CN213652106U discloses a household water treatment device, which has the following deficiencies in the field of water purification: 1. Insufficient utilization of the filtration area: The device only uses a partial area on the surface of the filter or filter element for water treatment, and fails to fully utilize the entire filtration area of the filter or filter element. 2.

[0035] The following will combine the attached drawings in the examples of the present utility model Figures 1-6 The technical solutions in the embodiments of the present utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0036] The present utility model provides a technical solution: a multi-purpose household water purification device, including a housing 1, a spacer 2 is hermetically fixed in the middle of the housing 1, a membrane filtration mechanism 3 is arranged at the left part inside the housing 1, and a carbon filter element 4 is fixed on the right side of the housing 1; an intermediate joint 5 is fixed at the axial center position of the spacer 2.
[0037] The housing 1 is the external structure of the entire water purification device, and its main function is to provide protection for the internal filtration mechanism and filter element, and at the same time ensure the safety and stability during the water purification process. An inlet valve 11 is arranged at the upper left end of the housing 1, a spray pipe 12 is fixed at the left part inside the housing 1, a tap water outlet valve 13 is arranged at the lower left end of the housing 1, and a purified water outlet valve 14 is arranged at the middle part on the right side of the housing 1. The inlet valve 11 is located at the upper left end of the housing 1, and it is the inlet of the entire device, used to control the flow rate of tap water entering the device. The user can adjust the inflow rate of tap water by operating the inlet valve 11 to ensure the normal operation and purification effect of the device under various working conditions. The spray pipe 12 is fixed at the left part inside the housing 1, and it is connected to the inlet valve 11 and is responsible for spraying tap water on the membrane filtration mechanism 3. The design of the spray pipe 12 ensures that the tap water can be evenly distributed on the surface of the membrane filtration mechanism 3, improving the filtration efficiency and purification effect. The tap water outlet valve 13 is arranged at the lower left end of the housing 1, and it is the ordinary water outlet of the device. When the user selects the ordinary water outlet, the tap water flows out through the tap water outlet valve 13 after being treated by the membrane filtration mechanism 3, which is suitable for general cleaning and washing water. The purified water outlet valve 14 is located at the middle part on the right side of the housing 1, and it is the purified water outlet of the device. After being double-purified by the membrane filtration mechanism 3 and the carbon filter element 4, the water flows out through the purified water outlet valve 14 and becomes clean and healthy drinking water with high-efficiency purification.
[0038] The spray pipe 12 is arranged at the lower end of the inlet valve 11 and is semicircular as a whole. A plurality of spray holes 121 are arranged in an array at the lower end of its semicircular contour. The spray pipe 12 plays a key role in distribution and diversion in the multi-purpose household water purification device. The following is a description of the functions of the spray pipe 12 and its related parts:
[0039] 1. Distribution function: The spray pipe 12 is located at the lower end of the inlet valve 11, and its design helps to evenly distribute the tap water entering the device onto the surface of the membrane filtration mechanism 3. When the tap water flows through the inlet valve 11 and enters the spray pipe 12, it first encounters the semicircular structure of the spray pipe 12, and then is evenly sprayed onto the surface of the membrane filtration mechanism 3 through the spray holes 121, ensuring that the tap water can fully cover and penetrate the entire surface of the filter.
[0040] 2. Diversion function: The semicircular structure of the spray pipe 12 and the arrangement of the spray holes 121 help to guide the flow of tap water. It ensures that the tap water flows out evenly from all the spray holes 121 of the spray pipe 12, forming a continuous and stable water flow, effectively covering and penetrating the entire surface of the filter.
[0041] 3. Improve filtration efficiency: By evenly spraying the tap water onto the surface of the membrane filtration mechanism 3 through the spray pipe 12, the use efficiency of the filter can be improved. The full contact between the tap water and the surface of the filter helps to more effectively remove impurities, solid particles, sediment, bacteria, viruses, etc. in the water.
[0042] 4. Reduce pressure loss: The design of the spray pipe 12 also helps to reduce the pressure loss of the water flow inside the device. By evenly distributing and diverting the tap water through the spray pipe 12, the flow rate and pressure of the water flow can be reduced, the resistance inside the device can be reduced, thereby prolonging the service life of the device and improving its stability.
[0043] In summary, the spray pipe 12 plays a key role in distribution, diversion, improving filtration efficiency and reducing pressure loss in the multi-purpose household water purification device. It ensures that the tap water can flow evenly and stably through the membrane filtration mechanism 3, thereby improving the purification effect and service performance of the device.
[0044] The spacer 2 is located in the middle of the housing 1. Its main function is to divide the housing 1 into two parts. One side is the membrane filtration mechanism 3, and the other side is the carbon filter element 4. The spacer 2 also provides a position for fixing the intermediate joint 5, ensuring the correct alignment and connection of the intermediate joint 5 with the housing 1, the membrane filtration mechanism 3, and the carbon filter element 4. The membrane filtration mechanism 3 is located in the left inner part of the housing 1. Its main function is to filter large molecular substances such as solid particles, sediment, bacteria, and viruses in water through a microporous membrane, improving the transparency and cleanliness of the water. The carbon filter element 4 is located on the right side of the housing 1. Its main function is to use activated carbon as a filtration medium, which can effectively remove organic compounds, chlorine, odors, and discoloration in water, improving the taste and quality of the water. The intermediate joint 5 is fixed at the axial center position of the spacer 2 and serves as a key component connecting the membrane filtration mechanism 3 and the carbon filter element 4. It ensures a smooth connection between the membrane filtration mechanism 3 and the carbon filter element 4, realizing continuous flow and efficient filtration during the water purification process.
[0045] The left side of the intermediate joint 5 is a cavity, sleeved on the right end of the delivery pipe 31; the right side of the intermediate joint 5 is closed and sleeved on the left end of the carbon filter element 4. A plurality of through water outlet holes 51 are arranged in an array on the outer contour of the middle part of the intermediate joint 5, and the water outlet holes 51 are arranged between the spacer 2 and the carbon filter element 4. The left side of the intermediate joint 5 is a cavity, and it is sleeved with the right end of the delivery pipe 31. This design enables tap water to flow smoothly from the delivery pipe 31 into the intermediate joint 5, providing a continuous water flow for subsequent membrane filtration and carbon filtration. A plurality of through water outlet holes 51 are arranged in an array on the outer contour of the middle part of the intermediate joint 5. These water outlet holes 51 are located between the spacer 2 and the carbon filter element 4, playing a role of guiding and diverting the flow. The design of the intermediate joint 5 ensures that tap water can flow continuously, pass through the carbon filter element 4 from the membrane filtration mechanism 3, and finally flow out the purified drinking water. It effectively connects and guides the flow, making the entire purification process continuous, efficient, and stable.
[0046] A water purification joint 41 is fixed to the right axial center of the carbon filter element 4, and the water purification joint 41 is connected to the water purification outlet valve 14. As a part of the carbon filter element 4, the water purification joint 41 is responsible for guiding the water filtered by the carbon filter from the carbon filter element 4 to the water purification outlet valve 14. The purified water processed by the carbon filter element 4 first flows through the water purification joint 41 and then smoothly flows into the water purification outlet valve 14.
[0047] On both sides of the housing 1, petal end caps 15 are symmetrically fixed. In the multi-purpose household water purification device, the petal end caps 15 play an important role in sealing and protection. The fixed design of the petal end caps 15 strengthens the structural support of the entire device, improving the stability and structural strength of the device. They help ensure that various components such as the membrane filtration mechanism, carbon filter core, intermediate joint, and water purification joint maintain the correct position and alignment during operation, avoiding displacement or deviation caused by external factors.
[0048] The membrane filtration mechanism 3 includes a delivery pipe 31 fixed between the left side of the housing 1 and the spacer plate 2. On both sides of the delivery pipe 31, end plates 32 are symmetrically arranged. On the outer contour of the delivery pipe 31, multiple groups of circular filter membranes 33 are arranged in an array. Between every two groups of filter membranes 33, a spacer ring 34 is fixed;
[0049] The delivery pipe 31 is fixed between the left side of the housing 1 and the spacer plate 2 and serves as the main channel for tap water. It ensures that tap water can flow smoothly through the membrane filtration mechanism 3 and thus enter the next filtration and purification process. On both sides of the delivery pipe 31, end plates 32 are symmetrically arranged, providing structural support and stability for the membrane filtration mechanism 3. The end plates 32 ensure the stable installation of the delivery pipe 31 and help evenly distribute the tap water flow, reducing flow rate differences and pressure losses. On the outer contour of the delivery pipe 31, multiple groups of circular filter membranes 33 are arranged in an array. These filter membranes 33 are the key filtration components of the membrane filtration mechanism 3, responsible for removing solid particles, bacteria, viruses, and other tiny impurities from tap water. The filter membranes 33 have a microporous structure and can effectively filter and capture the particles in the water, improving the transparency and cleanliness of the water. Between every two groups of filter membranes 33, a spacer ring 34 is fixed, which helps maintain a constant interval and alignment between the filter membranes 33. The spacer ring 34 ensures the stable layout and uniform spacing of the filter membranes 33, preventing contact and collision between the filter membranes 33, thereby improving the filtration efficiency and extending the service life of the filter.
[0050] On the outer contour of the delivery pipe 31, multiple through water holes 311 are arranged in an array. Water holes 311: On the outer contour of the delivery pipe 31, multiple through water holes 311 are arranged in an array. These water holes 311 allow tap water to flow from the membrane filtration mechanism 3 on the left side into the right side of the cavity. The design of the water holes 311 helps maintain the continuous and stable flow of tap water, improving the filtration efficiency and purification effect.
[0051] Working principle:
[0052] Water inlet stage: The user opens the water inlet valve 11, and tap water enters the housing 1. The spacer plate 2 divides the housing into two sealed parts.
[0053] Pretreatment stage: Tap water passes through the spray holes 121 on the spray pipe 12, causing the tap water to be evenly distributed on the membrane filtration mechanism 3. Here, the membrane filtration mechanism 3 begins to filter macromolecular substances, solid particles, sediment, bacteria, viruses, etc. in the water, improving the transparency and cleanliness of the water.
[0054] Continuous treatment stage: The water flow after pretreatment enters the left cavity of the intermediate joint 5 through the water passing holes 311 inside the conveying pipe 31, and then enters the carbon filter element 4 through a plurality of penetrating water outlet holes 51. Here, the carbon filter element 4 uses activated carbon as the filtering medium to effectively remove organic compounds, chlorine, peculiar smells, abnormal colors and other substances in the water, further improving the taste and quality of the water.
[0055] Purified water outlet stage: The water treated by the carbon filter element 4 flows into the purified water outlet valve (14) through the purified water joint 41 connected to the middle part of the carbon filter element 4, and the clean and healthy drinking water purified through two stages flows out from the purified water outlet valve (14).
[0056] Ordinary water outlet stage: If the user chooses to use the ordinary water outlet, the tap water will directly flow out from the tap water outlet valve 13. At this time, the water only passes through the treatment of the membrane filtration mechanism 3 and is suitable for general cleaning and washing water.
[0057] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
