Description

Portable Boiled Water Filter

technical field

The invention relates to a filter, in particular to a portable boiled water filter for filtering boiled water.

Background technique

Water is the source of life. Nutrients penetrate the whole body through water, and waste is excreted through water. Water is the most basic substance of life. Drinking water reasonably can not only strengthen the body, refresh the mind, and increase intelligence, but also prevent aging, prolong life, beautify, and detoxify.

As far as the current bottled and bottled drinking water market is concerned, it is basically pure water, mineral water and mineral water. While these drinking water bring convenience to people, they also cause many adverse factors to the human body. , and even caused people to have many misunderstandings in the concept of drinking water:

1. The purer the water, the better?

Pure water is water produced by multi-layer filtration of special devices. Many people think that the purer the water, the better. In fact, drinking pure water for a long time will lead to malnutrition in the body.

Nutritionists point out that after natural water is distilled and filtered, it not only removes harmful substances such as impurities and bacteria, but also filters out nutrients that are beneficial to the human body, because this kind of water molecules are not easy to pass through the cell membrane. It will lose the nutrients in the body, reduce the body's immunity, and also change the healthy slightly alkaline body in the body, affect the activity of nerves, muscles and various enzymes, and cause diseases. Purified water has a strong ability to dissolve various trace elements, compounds, and nutrients. After drinking, it will dissolve the trace elements in the body and excrete them from the body. Long-term drinking without timely supplementation may cause disease, so it is not suitable for people with excess nutrition. People drink for a long time.

Water is an important way for the body to obtain minerals. The United States, Western Europe, Japan and other countries seldom include ultrapure water in the scope of drinking water. Experts warn that pure water is suitable as a supplement to drinking water, and is not suitable for long-term drinking, especially for primary and middle school students, pregnant women, the elderly and those in the process of growth and development. People with cardiovascular disease and diabetes.

2. Mineral water is healthy water?

According to experts in geology, groundwater is not necessarily mineral water. The formation of mineral water requires a specific geographical environment. It takes decades or even hundreds of years to form. It is rich in minerals and trace elements necessary for the human body. Physiological functions have positive effects and are extremely valuable and limited mineral resources. Therefore, in European countries with a regular mineral water market, the price of mineral water is several times that of other beverages of the same capacity.

However, there are many types of "mineral water" on the market at present, and there are common problems in all of them:

(1) The active substances in the water are all lost after filling, lose their activity, and become "dead water";

(2) Poor packaging containers or unclean disinfection, poor sealing and contamination during transportation;

(3) Degradation of water functions and pollution of water sources (acid rain, pesticides, waste water, heavy metals, etc.) are inevitable;

(4) The content of trace elements in water is single, which is not easily absorbed by the human body;

(5) The level of filtration process and equipment varies, and it is difficult to distinguish between true and false.

3. Is mineral water good water?

The atmosphere has been polluted by various radiations and harmful substances, and there is no clean water within 300 meters of the surface due to various pollutions. Mineral water is no longer safe drinking water; the disadvantages of pure water are also well known. Therefore, in order to cater to consumers, some companies artificially add minerals to purified water. Some water dispensers first use reverse osmosis to turn tap water into pure water, and then pass through a mineral column to dissolve certain minerals in the water. However, the proportion of minerals added in this way cannot meet the minerals and trace elements needed by the human body. On the contrary, when the mineral content in the water exceeds the standard, it will also endanger human health. This method is only to meet people's psychological needs. .

Due to the above reasons, people have realized the various disadvantages of bottled water, and thus turned to the purification of tap water for drinking. As far as the current purification methods of tap water are concerned, they are basically divided into the following types: (1), activated carbon type purification water tank:

Only activated carbon is used as the filter material, which is generally used in simple water purifiers and water purifiers that require a large amount of activated carbon for adsorption. Generally, it mainly removes organic substances such as chlorine and trihalomethanes. In addition, the water remaining in the filter element has no residual chlorine, and it is easier to breed various bacteria, which is more dangerous. (2), hollow fiber membrane water purifier:

A water purifier that utilizes the adsorption capacity of activated carbon and the ultrafine particle removal capacity of hollow fiber membranes. Compatible with various environmental pollution of tap water. It can remove residual chlorine, turbid objects, organic matter, trihalomethanes, pesticides and other harmful substances, and heavy metals and other minerals in the water will not be removed. (3), reverse osmosis membrane water purifier (RO Reverse Osmosis):

The pore size of the reverse osmosis membrane is finer than that of the hollow fiber membrane. When filtering, it needs external pressure to pass through, and the inorganic substances in the water will be removed. It was first used for seawater desalination, and it is currently used in large-scale facilities such as water pipes in the United States and other places. In Japan, ordinary households do not use this technology for water purifiers. Because this method also removes useful ions, it is not suitable for long-term drinking. Moreover, a large amount of waste water will be produced. Today, when water resources are tense, it is impossible to be widely accepted by people's society.

These forms of filter materials are collectively referred to as "deep" filter materials, and long-term use has the problem of secondary pollution of drinking water due to the pollution of the filter element.

The above multiple methods and forms are all methods for processing cold water. In addition to many unfavorable factors in the processing process, the concept of "boiled water filtration" has been ignored. This is because the concept of water filtration and the development of equipment are basically from developed countries such as Europe and the United States. Their contribution to cold water filtration is undeniable. However, the drinking habits of Chinese and even Asians are completely different from those of Europeans and Americans. Most Chinese drink hot water, while Europeans and Americans drink cold water. A difference between hot and cold will result in a large difference in water filtration. concept! Because the free calcium and magnesium ions in the water react chemically during the heating process to form calcium carbonate, magnesium carbonate, magnesium hydroxide, nitrite and other precipitates, which simultaneously adsorb heavy metal ions such as mercury, cadmium, lead and arsenic , forming scale. If not filtered and eliminated in time, these harmful substances will enter the human body together with the water, causing neurological, digestive, urinary and hematopoietic system lesions and dysfunction, especially arsenic and cadmium can cause cancer, cause fetal malformation, and endanger health.

In addition, the purpose of boiling water is to sterilize bacteria (microorganisms). After the bacteria are killed, their corpses still remain in the water. If they are not filtered and removed, these corpses and their metabolites will enter the human body and become what is called "hot water" in medicine. Primogen", resulting in "nameless fever".

As far as the filter material is concerned, the existing filter materials are all "deep" filter materials, which have poor temperature resistance and are easily deformed or undergo chemical and physical changes when exposed to heat; the filter resistance is large, and it is difficult to achieve ultra-low pressure filtration. Filtration accuracy will be greatly reduced, so how to solve the problem of boiling water filtration is the subject of our painstaking research.
