Description

Technical Field

[0001] The present application belongs to the field of water purifiers, and in particular to a water purifier for adjusting water quality. Background Art

[0002] At present, water purifiers using RO reverse osmosis technology are the mainstream direct drinking water products on the market and have a certain popularity rate. However, after the water purifier has been shut down for a period of time, the first cup of water received has a bad taste. The reason is that when the water purifier is in a static state, the solutes in the wastewater will penetrate through the RO membrane into the pure water end. Especially when the water purifier is shut down for a long time, under the phenomenon of two-way osmosis, the remaining wastewater in the pipeline will slowly penetrate through the RO membrane into the pure water end, resulting in a higher TDS (total dissolved solids) value for the first cup of water. The higher the TDS value, the more solid dissolved matter is contained in the water, and water with a high TDS value will have some unpleasant taste and taste, such as bitterness and saltiness, which affects the drinking experience.

[0003] Moreover, the pH value of water treated by reverse osmosis (RO) technology is generally between 6.5 and 6.8, which is weakly acidic. Although it meets the national standards for drinking water formulated by my country, its low pH value may not be suitable for long-term drinking by all people. Especially for some special groups, such as those with insufficient gastric acid secretion or gastric diseases, long-term drinking of weakly acidic RO water may aggravate stomach discomfort. In addition, while RO water removes impurities in water, it also often reduces the content of mineral elements. These elements play an important role in human health. For example, calcium and magnesium are essential for bone health, while zinc and selenium are involved in the activation and metabolism of various enzymes. Long-term drinking of RO water, if these trace elements are not supplemented through other channels, theoretically there is a risk of causing trace element deficiency in the body. In order to ensure the safety and health of drinking water, it is necessary to make appropriate adjustments to drinking water according to one's own health status and taste preferences when choosing drinking water.

For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are connected to form a whole only through a connecting structure. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0026] In the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0027] The utility model is described below in conjunction with the accompanying drawings.

[0028] The specific plans adopted are:

[0029] like Figure 1-2As shown, the utility model provides a water purification device for adjusting water quality, which is arranged behind a reverse osmosis system. The reverse osmosis system includes an RO membrane 2, a high-pressure pump and a security filter arranged to protect the reverse osmosis membrane, and is used to adjust the water quality of RO water. The device includes a body 1, a water storage chamber 3, a detection component 6 for detecting water quality parameters in the water storage chamber, and a water inlet pipeline connected to the water storage chamber. The water inlet pipeline includes a first water inlet pipeline 4 and a second water inlet pipeline 5. One end of the first water inlet pipeline and the second water inlet pipeline are respectively connected to a first port and a second port of a three-way solenoid valve 8, the third port of the three-way solenoid valve is connected to the water storage chamber, the other end of the first water inlet pipeline is connected to the RO water outlet pipeline, the other end of the second water inlet pipeline is connected to a water purification module capable of adjusting water quality parameters and then connected to the water storage chamber, the detection component controls the action of the three-way solenoid valve according to the detected water quality parameters to adjust the water inlet flow path of RO water entering the water storage chamber to adjust the water quality parameters to meet the drinking water needs of different groups of people.

[0030] Specifically, the first water inlet pipeline is directly connected to the RO water outlet pipeline, and is used to introduce untreated RO water into the three-way solenoid valve and then into the water storage chamber. The second water inlet pipeline is connected to the water purification module that can adjust the water quality parameters. According to the instructions of the detection component, it controls whether the RO water enters the water storage chamber directly through the first water inlet pipeline, or enters the water storage chamber after passing through the water purification module through the second water inlet pipeline. The water purification module can be configured with different processing units according to needs, such as a mineralization unit for increasing the mineral content of water and adjusting the pH value, or a degassing unit for removing gas in water, etc., to meet different water quality adjustment needs.

[0031] When working, the detection component continuously monitors the water quality parameters in the water storage chamber, such as TDS value or pH value. If the TDS value is higher than the set value, the three-way solenoid valve is adjusted to allow the RO water to enter the water storage chamber mainly through the first water inlet pipeline and mix with the stored water to reduce the TDS value and improve the taste. If the pH value needs to be adjusted, the RO water is guided to enter the water purification module 7 through the second water inlet pipeline, and then enter the water storage chamber after corresponding treatment (such as mineralization or addition of alkaline substances) to reach the desired pH value range.

[0032] With the water purification device of the present application, users can adjust water quality parameter standards according to their own health conditions and taste preferences by setting different water purification modules, and the device will automatically adjust to meet these needs. Through such a design, the water purification device not only solves the problem of poor taste of the first cup of RO water after shutdown, but also provides a more flexible and personalized water quality adjustment plan, which meets the diverse needs of different groups of people for drinking water and helps to improve the quality of life.

[0033] See also Figure 1In this embodiment, the water purification module includes a shell 70, in which a water quality parameter adjustment unit 71 is provided. The shell includes a water inlet end 700 and a water outlet end 701. The water inlet end is connected to the second water inlet pipeline through a pipeline, and the water outlet end is connected to the water storage chamber. After the RO water flows through the water quality parameter adjustment unit, the water quality parameters can be adjusted to meet specific needs.

[0034] The water quality parameter adjustment unit can be a pH value treatment component: used to adjust the acidity and alkalinity (pH value) of water. According to user needs or health standards, the water can be adjusted to weak alkalinity or maintained in a neutral range to meet the drinking needs of different groups of people. Mineral additives: Add appropriate amounts of mineral elements such as calcium, magnesium, zinc, selenium, etc. to the water to supplement the minerals that may be removed during the treatment of RO water. You can choose the functional ceramic filter element produced and sold by Shandong Xinyongheng New Materials Co., Ltd., such as magnesium-rich slow-release mineralized materials / calcium-rich slow-release ore materials or zinc-rich slow-release mineralized materials. Water purification components: further purify RO water, remove possible residual trace impurities, odors or colors, and improve the clarity and taste of the water.

[0035] In addition, only one water purification module can be set, or different water purification modules can be combined according to needs to flexibly respond to various water quality adjustment needs. It can accurately adjust the drinking water needs of specific groups of people or specific occasions to meet diverse needs.

[0036] The shell is fixedly connected or detachably connected to the body 1, wherein the detachable connection makes the maintenance process simpler and more direct. The maintenance personnel do not need to disassemble the entire device, but only need to operate the part with the problem, thereby reducing the difficulty and cost of maintenance. The water purification device is designed as a detachable modular structure, which can easily add or remove certain functional modules to meet different processing requirements.

[0037] Specifically, the body 1 is provided with a snap ring 10, and the shell is detachably provided on the snap ring 10. The water outlet of the shell is connected to the water storage chamber through a pipeline, and the snap connection cooperates with the snap ring 10 of the corresponding part on the body 1 through the protrusion or groove on the shell to form a clamping effect. This connection method does not require additional fasteners, and can be connected and disassembled by simply pressing. Of course, threaded connection, magnetic connection, slide rail and other detachable connection methods can also be used, which will not be repeated in this application.

[0038] As a preferred embodiment of the present application, see Figure 2 A quick connector 12 is provided between the RO water inlet pipe and the second water inlet pipe, and between the RO water inlet pipe and the first water inlet pipe. The design of the quick connector makes the connection and disassembly between the pipes very simple and quick. Without complicated tools or professional skills, users or technicians can quickly complete the installation and replacement work.

[0039] As a preferred embodiment of the present application, the probe can be directly set in the water storage chamber, but since directly opening a hole in the water storage chamber requires precise processing technology to ensure that the position, size and shape of the hole meet the requirements, this increases the manufacturing difficulty and cost. Therefore, in this embodiment, a partition is provided in the water storage chamber to separate the water storage chamber into an upper water storage chamber 30 and a lower water storage chamber 31, and the water outlet 11 of the body 1 is provided in the upper water storage chamber. The upper water storage chamber and the lower water storage chamber are both provided with a pipe interface connecting the two cavities, and the pipe interface is provided with a three-way quick connector 9, and the pipe interface is set as close to the bottom as possible, so that the detection component The probe 60 is arranged in the three-way quick connector to realize water quality detection, and can be processed and assembled using existing manufacturing processes and equipment to reduce processing difficulty and cost. Specifically, RO water first enters the lower water storage chamber through the first water inlet pipeline, and then fills the lower water storage chamber and comes to the upper water storage chamber for water storage through the pipe interface and the three-way connector. After the probe contacts the water, it detects the water quality parameters, and changes the water inlet flow channel according to the design, so that the water quality parameters in the entire water storage chamber are adjusted to meet the needs of the human body before being discharged from the water outlet 11 for people to use, ensuring that the water quality of the final outlet is safe and meets the needs of the human body.

[0040] As a preferred embodiment of the present application, the body 1 is also provided with a placement cavity, the detection assembly, i.e., the controller 61, the probe, the wire and the three-way solenoid valve are arranged in the placement cavity, the placement cavity is provided with a cover 13, the cover 13 is detachably connected to the body 1, the existence of the cover 13 effectively isolates dust, dirt and other impurities in the external environment from entering the placement cavity, thereby protecting the probe assembly, the three-way solenoid valve and other components from contamination and damage, the detachable cover 13 design allows maintenance personnel to more intuitively understand the internal structure layout and component status, thereby more accurately determining the problem and taking corresponding maintenance measures. This greatly simplifies the maintenance process and improves maintenance efficiency.

[0041] The parts not described in the present invention can be realized by adopting or drawing on the existing technology.

[0042] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
