Description

Technical Field

[0001] This utility model belongs to the technical field of water supply devices, specifically relating to a water supply device with adjustable mineral concentration. Background Technology

[0002] Since purified water contains no minerals and is slightly acidic, using it as the sole source of drinking water is not good for human health. Adding minerals to water can not only supplement the body with trace elements, but also have a positive effect on the gut microbiota. Therefore, many users now drink mineral water or use mineral water dispensers to obtain mineral water.

[0003] However, current mineral water dispensers use a pre-prepared method to obtain mineral water of a specific concentration. But after a period of settling, the first sample often shows a high mineral concentration. When the mineral content in the water tank is high, it not only deteriorates the taste but may also pose potential health risks. Excessive minerals entering the body can cause a series of adverse effects, as high mineral content can lead to an imbalance in mineral intake, causing deficiencies in calcium, zinc, and iron. In severe cases, this can result in osteoporosis, weakened immunity, and anemia. Conversely, when the mineral content is too low, it cannot meet the body's needs, and existing mineral water dispensers cannot promptly regulate the mineral content in the tank to increase and maintain it within a reasonable range. Therefore, a water supply device is needed that can appropriately regulate the mineral content in the water tank, maintaining it within a reasonable range to benefit human health. Utility Model Content

[0004] This invention provides a water supply device with adjustable mineral concentration to solve the problem of excessively high mineral content in the water output by existing mineral water dispensers, especially in the first cup. It appropriately adjusts the mineral content to keep it within a reasonable range for human consumption.

[0005] The technical solution adopted in this utility model is as follows:

[0015] The first mineralization filter includes a first filter housing and a first filter media; the first filter housing is filled with the first filter media, one end of the first filter housing has a first connection port, and the other end of the first filter housing has a second connection port. The second connection port is used to connect to the water supply outlet pipeline, and the first connection port is used to connect to the first water supply branch. The diameter of the second connection port is smaller than the diameter of the first filter media to prevent the first filter media from flowing out of the second connection port.

[0033] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0034] Example 1

[0035] This utility model relates to a water supply device with adjustable mineral concentration, such as... Figure 1 As shown, the system includes a water tank 1, an inlet pipe 2, a first water supply pipe 3, a second water supply pipe 4, a TDS probe 5, and a filter assembly 6. The water tank 1 has a first inlet 10 connected to the first water supply pipe 3 and a second inlet 11 connected to the second water supply pipe 4. The first water supply pipe 3 and the second water supply pipe 4 are connected to the inlet pipe 2 via a first electromagnetic three-way valve 13. The TDS probe 5 is connected to the bottom of the water tank 1 and is used to detect the mineral concentration value in the water tank 1. The filter assembly 6 is connected between the second water supply pipe 4 and the water tank 1. The filter assembly 6 includes multiple mineralization filter elements. The mineralization filter elements include mineral materials that can impart minerals to the water flow, thereby increasing the mineral content of the water flow after passing through the mineralization filter elements.

[0036] When the TDS probe 5 detects a concentration higher than the set threshold, the first electromagnetic three-way valve 13 connects the first water supply line 3 to the inlet line 2, and pure water enters the water tank 1 through the first water supply line 3; when the TDS probe 5 detects a concentration lower than the set threshold, the first electromagnetic three-way valve 13 connects the second water supply line 4 to the inlet line 2, and pure water enters the filter assembly 6 through the second water supply line 4 to increase the mineral content before entering the water tank 1.

[0037] The purpose of this application's adjustable mineral concentration water supply device is to regulate the mineral concentration in water tank 1. Current mineral water dispensers use a pre-preparation method to obtain mineral water of a specific concentration, but after a period of settling, the initial water sample often shows a high mineral concentration. When the mineral content in water tank 1 is high, it not only leads to a deterioration in taste but may also pose potential health risks. Excessive minerals entering the body can cause a series of adverse effects, as high mineral content in water can lead to an imbalance in mineral intake, causing problems such as calcium, zinc, and iron deficiencies. In severe cases, it may cause osteoporosis, weakened immunity, and anemia. However, minerals in water can also have a positive impact on intestinal flora. Therefore, reasonably regulating the mineral content in water tank 1 to maintain it within a reasonable range is beneficial to human health. The device in this application can monitor the mineral content in real time and dynamically add different component aqueous solutions to ensure that every dispensed drinking water meets the mineral concentration standard.

[0038] In use, the mineral concentration in water tank 1 is detected by TDS probe 5. When the detected mineral concentration is higher than the set threshold, the first electromagnetic three-way valve 13 is opened to connect the inlet pipe 2 with the first water supply pipe 3. Pure water flows into water tank 1 through inlet pipe 2, first water supply pipe 3, and first inlet 10, and flows out through outlet 12. When the detected mineral concentration is lower than the set threshold, the second electromagnetic three-way valve 14 is opened to connect the inlet pipe 2 with the second water supply pipe 4. Specifically, it is connected to the water supply inlet pipe 41 in the second water supply pipe 4. The flow meter 15 connected to the water supply inlet pipe 41 detects the liquid flow rate entering the water supply inlet pipe 41. When the flow rate does not reach the set threshold, the second electromagnetic three-way valve 14 is opened to connect the water supply inlet pipe 41 with the first water supply branch 8, and then the water flows through... Water flows through inlet pipe 2, water supply inlet pipe 41, first water supply branch 8, and first mineralization filter to increase mineral content, then through water supply outlet pipe 42 and second inlet 11 into water tank 1. When the flow rate reaches a set threshold, the second electromagnetic three-way valve 14 is opened to connect water supply inlet pipe 41 with second water supply branch 9, while water supply inlet pipe 41 is not connected to first water supply branch 8. Water flows through inlet pipe 2, water supply inlet pipe 41, second water supply branch 9, and second mineralization filter to increase mineral content, then through water supply outlet pipe 42 and second inlet 11 into water tank 1. To ensure thorough mixing of water and minerals, the water in water tank 1 is stirred by activating stirring device 16, resulting in more uniform and thorough mixing of minerals in the water. The water can then flow out through outlet 12 of water tank 1 for user use.

[0039] In a preferred embodiment, the water tank 1 has an ellipsoidal or spherical structure; the first water inlet 10 and the second water inlet 11 are located on both sides near the bottom of the water tank 1, and the water tank 1 also has a water outlet 12 at the upper position.

[0040] The water tank 1 has an ellipsoidal or spherical structure to ensure thorough mixing of the water and minerals entering the tank. The ellipsoidal or spherical shape, due to its arc-shaped form, promotes the formation of a more uniform vortex when mixing or stirring the liquid within the tank. The first inlet 10 is for introducing pure water, and the second inlet 11 is for introducing water with increased mineral concentration. The outlet 12 is located at the upper part of the water tank 1, while the first inlet 10 and the second inlet 11 are located at the lower part, facilitating water flow from the bottom of the tank 1 for thorough mixing.

[0041] The arrangement of the water outlet 12 and its connecting pipe 19 in this application can include various implementation methods, including but not limited to those described below:

[0042] In a preferred embodiment, the outlet 12 is connected to the outlet pipe 7, and the water overflows through the outlet pipe 7.

[0043] The water outlet 12 is located at the top of the water tank 1. Water entering the water tank 1 through the first water inlet 10 or the second water inlet 11 can overflow through the water outlet 12 and flow out to the outside through the water outlet pipe 7 connected to the water outlet 12 for user convenience.

[0044] In another preferred embodiment, the outlet 12 is connected to one side of the outlet pipe 7, the other side of the outlet pipe 7 is connected to the heater 18, and the other side of the heater 18 is connected to the connecting pipe 19, through which water flows out.

[0045] The outlet 12 is connected to the outlet pipe 7. One end of the outlet pipe 7 is connected to the outlet 12, and the other end of the outlet pipe 7 is connected to the heater 18. This allows the water flowing out of the outlet 12 to be heated by the heater 18 and then flow out through the connecting pipe 19, so that the user can use hot water. When the user does not use hot water, the heater 18 can be turned off and used as a pipe to output room temperature water.

[0046] In a preferred embodiment, the second water supply pipeline 4 includes a water supply inlet pipeline 41 and a water supply outlet pipeline 42; one end of the water supply inlet pipeline 41 is connected to the water supply pipeline 2 through a first electromagnetic three-way valve 13, and the other end of the water supply inlet pipeline 41 is connected to a first water supply branch 8 and a second water supply branch 9 through a second electromagnetic three-way valve 14; the first water supply branch 8 and the second water supply branch 9 are respectively connected to the water supply outlet pipeline 42, and are connected to the second water inlet 11 of the water tank 1 through the water supply outlet pipeline 42.

[0047] like Figure 1 As shown, the second water supply pipeline 4 includes a water supply inlet pipeline 41 and a water supply outlet pipeline 42. The water supply inlet pipeline 41 is used to connect with the water supply pipeline 2. The opening of the first electromagnetic three-way valve 13 enables the water supply pipeline 2 to be connected to the water supply inlet pipeline 41 or the first water supply pipeline 3. When the water supply pipeline 2 is connected to the water supply inlet pipeline 41, the water supply pipeline 2 is not connected to the first water supply pipeline 3. When the water supply pipeline 2 is connected to the first water supply pipeline 3, the water supply pipeline 2 is not connected to the water supply inlet pipeline 41. This allows pure water to flow through the water supply pipeline 2 and the first water supply pipeline 3 into the water tank 1, or the water flows through the water supply inlet pipeline 41 and the filter assembly 6 of the second water supply pipeline 4, and the mineral content increases before entering the water tank 1.

[0048] Since the filter assembly 6 includes multiple mineralization filters, preferably two in this application, labeled as the first mineralization filter and the second mineralization filter, the filtration volumetric flow rate of the first mineralization filter is limited. For example, it can achieve good performance in increasing mineral content within the range of 1000ml. When the flow rate exceeds this, its performance decreases. Therefore, in order to ensure that the mineral content in the water tank 1 remains at a stable value according to the water volume demand, this application sets up a first mineralization filter and a second mineralization filter. In practical applications, more mineralization filters can also be set up, and their arrangement can be adjusted according to the required water volume. The flow meter 15 is used for detection. When the set threshold is not reached, the second electromagnetic three-way valve 14 can be opened. When the first water supply branch 8 is connected to the water supply inlet pipe 41, while the second water supply branch 9 is not connected to the water supply inlet pipe 41, the water flows through the inlet pipe 2, the water supply inlet pipe 41, the first water supply branch 8 and the first mineralization filter, and then through the water supply outlet pipe 42 and the second inlet 11 into the water tank 1. When the set threshold is reached, the second electromagnetic three-way valve 14 can be opened to connect the second water supply branch 9 to the water supply inlet pipe 41, while the first water supply branch 8 is not connected to the water supply inlet pipe 41. At this time, the water flows through the inlet pipe 2, the water supply inlet pipe 41, the second water supply branch 9 and the second mineralization filter, and then through the water supply outlet pipe 42 and the second inlet 11 into the water tank 1.

[0049] In a preferred embodiment, a flow meter 15 is also connected to the water supply inlet pipe 41 to detect the flow rate entering the water supply inlet pipe 41. When the flow rate reaches a set threshold, the water supply inlet pipe 41 is connected to the water supply branch pipe through the second electromagnetic three-way valve 14.

[0050] The flow meter 15 installed on the water supply inlet pipe 41 can be used to detect the flow rate entering the water supply inlet pipe 41, thereby determining whether to connect the first water supply branch 8 to the water supply inlet pipe 41 or the second water supply branch 9 to the water supply inlet pipe 41. When the flow rate reaches the set threshold, the second electromagnetic three-way valve 14 opens, connecting the water supply inlet pipe 41 to the second water supply branch 9. When the flow rate does not reach the set threshold, it proves that the flow rate has not reached the flow limit of the first mineralization filter. Therefore, at this time, it is not necessary to connect the second electromagnetic three-way valve 14 to the second water supply branch 9 to the water supply inlet pipe 41, and the first water supply branch 8 can still be connected to the water supply inlet pipe 41.

[0051] In a preferred embodiment, the filter assembly 6 includes a first mineralization filter and a second mineralization filter; the first mineralization filter is connected to the first water supply branch 8, and the first mineralization filter includes a first mineralization filter element; the second mineralization filter is connected to the second water supply branch 9, and the second mineralization filter includes a second mineralization filter element.

[0052] This application preferably uses a two-stage filtration system. The filter assembly 6 includes a first mineralization filter and a second mineralization filter. The first mineralization filter is connected to the first water supply branch 8, and the second mineralization filter is connected to the second water supply branch 9. When the TDS probe 5 detects that the mineral content in the water tank 1 is low, below a set threshold, the first electromagnetic three-way valve 13 is activated to connect the inlet pipe 2 to the second water supply pipe 4. The second electromagnetic three-way valve is also activated to connect the water supply inlet pipe 41 of the second water supply pipe 4 to the first water supply branch 8. After the water flows through the inlet pipe 2, the water supply inlet pipe 41, and the first water supply branch 8, the mineral content increases after passing through the first mineralization filter on the first water supply branch 8. After the mineral content is increased, the water flows to the water tank 1 through the water supply outlet pipe 42 and the second water inlet 11. When the flow meter 15 detects that the water volume has reached the preset threshold, the first electromagnetic three-way valve 13 remains open and keeps the water supply inlet pipe 41 of the water supply pipe 2 connected to the water supply inlet pipe 4 of the second water supply pipe 4. By controlling the second electromagnetic three-way valve 14 to open, the water supply inlet pipe 41 is closed to the first water supply branch 8, and the water supply inlet pipe 41 is connected to the second water supply branch 9. After the water flows through the water supply pipe 2, the water supply inlet pipe 41, and the second water supply branch 9, the water increases its mineral content through the second mineralization filter on the second water supply branch 9, and then flows to the water tank 1 through the water supply outlet pipe 42 and the second water inlet 11.

[0053] Furthermore, the first mineralization filter includes a first filter housing and a first filter media; the first filter housing is filled with the first filter media, one end of the first filter housing has a first connection port, and the other end of the first filter housing has a second connection port. The second connection port is used to connect to the water supply outlet pipe 42, and the first connection port is used to connect to the first water supply branch 8. The diameter of the second connection port is smaller than the diameter of the first filter media to prevent the first filter media from flowing out of the second connection port.

[0054] Water from the first water supply branch 8 enters the first filter housing through the first connection port. While being filtered by the first filter media inside the first filter housing, the first filter media reacts with the water, increasing the mineral content in the water from the first water supply branch 8. The water with increased minerals flows into the water tank 1 through the water supply outlet pipe 42 and the second inlet 11.

[0055] Furthermore, the second mineralization filter includes a second filter housing and a second filter media; the second filter housing is filled with the second filter media, one end of the second filter housing has a first connecting port, and the other end of the second filter housing has a second connecting port. The second connecting port is used to connect to the water supply outlet pipe 42, and the first connecting port is used to connect to the second water supply branch 9. The diameter of the second connecting port is smaller than the diameter of the second filter media to prevent the second filter media from flowing out of the second connecting port.

[0056] Water from the second water supply branch 9 enters the second filter housing through the second connecting port. While being filtered by the second filter media inside the second filter housing, the second filter media reacts with the water, increasing the mineral content in the water from the second water supply branch 9. The water with increased minerals flows into the water tank 1 through the water supply outlet pipe 42 and the second inlet 11.

[0057] In a preferred embodiment, the water supply device with adjustable mineral concentration of this application further includes a stirring device 16. The stirring device 16 includes a bracket 161, a drive mechanism 162, a connecting shaft 163, and stirring blades 164. The bracket 161 is connected to the outside of the water tank 1, the drive mechanism 162 is connected to the top of the bracket 161, and the connecting shaft 163 is disposed inside the water tank 1 with one end extending out of the water tank 1 and connected to the drive mechanism 162. Stirring blades 164 for stirring the water flow in the water tank 1 are connected to the connecting shaft 163.

[0058] like Figure 1As shown, to increase the uniformity and thorough mixing of minerals and pure water in water tank 1, this application also includes a stirring device 16. Since water tank 1 has an ellipsoidal or spherical structure, a bracket 161 is connected to the top of water tank 1. Openings are provided on both sides of the bottom of bracket 161 for the first water supply pipe 3 and the second water supply pipe 4 to pass through, respectively. An opening is provided at the top of bracket 161 for the outlet pipe 7 to pass through, and an opening is provided at the top of bracket 161 for the connecting shaft 163 to pass through. The stirring device 16... A drive mechanism 162 is connected to the top of the bracket 161. The drive mechanism 162 uses a drive motor, and the shaft of the drive motor is connected to a connecting shaft 163. The connecting shaft 163 can extend into the water tank 1 through an opening at the top of the bracket 161. The top of the water tank 1 has an opening slot corresponding to the opening at the top of the bracket 161. The connecting shaft 163 extends into the interior of the water tank 1 through the opening slot. A stirring blade 164 is connected to the connecting shaft 163, which can stir the water flow in the water tank 1 and accelerate the thorough mixing between the water flow and minerals in the water tank 1. The stirring blade 164 includes a first stirring blade 1641 and a second stirring blade 1642. The first stirring blade 1641 is spirally connected above the connecting shaft 163, and the second stirring blade 1642 includes multiple blades radially connected below the connecting shaft 163.

[0059] Example 2

[0060] This application relates to a water supply device with adjustable mineral concentration according to another embodiment, such as... Figure 2 As shown, the only difference between this embodiment and Embodiment 1 is that there is no stirring device in the water tank 1 in Embodiment 2. A baffle can be connected at any position inside the water tank, which can be located at the bottom, side, or top of the water tank. At least one baffle is connected. Preferably, at least one baffle 20 is connected to the bottom of the water tank 1, and the baffle 20 is arranged vertically. The baffle 20 can be located near the water inlet pipe 2, away from the water inlet pipe 2, or in the middle of the bottom of the water tank 1. Preferably, the baffle 20 is connected to the middle of the bottom of the water tank.
