It is a collection of multiple minerals and contains macroelements of potassium, sodium, calcium, magnesium and phosphorus, and eighteen microelements of zinc, iron, selenium, copper, strontium, iodine, fluorine and metasilicic acid. The method mainly comprises the steps of plagioclase feldspar and potassium feldspar, and secondly comprises quartz, amphibole, biotite, byproduct fossilized stone and the like. Under the normal condition, the contents of four trace elements metasilicic acid, sr, zn and F in the medical stone dissolved solution reach or are close to the national beverage mineral water standard. Ancient times, three grass schema, recorded "Maifanitum, with sweet and warm taste and no toxicity". The shifeng medical stone is "shenshi", "longlife stone" and "healthy stone". Modern scientific analysis proves that the medical stone is rich in various elements, has biological activity, and can improve the physiological function of organisms and bidirectionally regulate the pH value; can strongly adsorb toxic and harmful substances in water and peculiar smell in air, can dissolve out various microelements, and is a natural nutrition source. Medical stones are now widely used in japan, korea, southeast asia, etc. countries and regions.

Mineral water filtered through medical rice Dan Yanceng is called medical spring. Because medical stone is used for treating pain, dense discharge and wound in Chinese medicine, medical stone has been claimed to have the functions of preventing diseases and aging. The following description of medical stones by the compendium of materia medica follows: the medical stone is in mountain stream, and the stone has different sizes, or is like fist, or is like goose egg, or is like cup or cake. Roughly like holding a roll of medical rice. There are particles, such as beans like rice, which are yellow-white in color. However, this is the case in Lindera serrulata. Smell: sweet, warm and nontoxic. It is used for treating all paralysis, cellulitis and hair back. According to the above description, medical stone is named according to its shape. The Chinese medicine is classified into the materials for treating diseases, and the minerals are related. It is also known as a healthy stone.

Further, a hot pot handle 4311 is provided on the hot pot body 431.

The practical method of the hot pot table comprises the following steps:

(1) When the food in the side pot cavity is boiled, the upper liquid level sensor 433 positioned in the side pot cavity feeds back information, the electromagnetic valve 437 on the two sides is opened, the two electric control variable water pumps 438 work, the soup in the pot is pumped down by the side pot cavity, the soup is pumped into the filtering device 44 for grease absorption, and the soup enters the other pot cavity through the quick connection pipeline 436; when the liquid level in the side pot cavity is lower than the position of the lower liquid level sensor 434, the side soup electromagnetic valve 437 is closed, meanwhile, the electromagnetic oven 42 on the same side is closed, and the electromagnetic oven 42 on the other side is opened for heating; when the soup is insufficient, the water supplementing one-way valve 452 in the water supplementing device 45 is opened, the side soup electromagnetic valve 437 is opened at the same time, and the filter element driving motor 444 can be started at the same time, and the driving gear 443 drives the circumferential gear 442 to rotate, so that the filter element main body 3 is driven to rotate, and the electric control two-way variable water pump 438 works, so that soup supplementing is performed;

(2) At the end, the drain solenoid valve 462 is opened to drain the remaining soup in the quick connect line 436 and cartridge.

The working principle of the hot pot table is as follows:

the hot pot isolation plate 430 divides the hot pot body 431 into a left pot cavity and a right pot cavity, the hot pot body 431 is provided with a lower liquid level sensor 434 and an upper liquid level sensor 433, the lower liquid level sensor 434, the upper liquid level sensor 433, a soup electromagnetic valve 437 and a bidirectional variable water suction pump 438 are electrically connected with a controller, the controller receives signals of the liquid level heights transmitted by the lower liquid level sensor 434 and the upper liquid level sensor 433 and controls the opening and closing of the soup electromagnetic valve 437 and the bidirectional variable water suction pump 438, when the time of food boiling in the left pot cavity arrives, the upper liquid level sensor 433 positioned in the left pot cavity feeds back information, the left soup electromagnetic valve 437 and the right soup electromagnetic valve 437 are opened, the electric control two bidirectional variable water suction pumps 438 work, soup in the pot is pumped down by the left pot cavity, soup is sucked by an intermediate filter element, filtered soup is pumped into the right pot cavity of the hot pot 43 to be used until the liquid level in the left pot cavity is lower than the position of the lower liquid level sensor, and simultaneously the left electromagnetic valve 434 and the right electromagnetic oven 42 are closed, and the right electromagnetic oven 42 is opened. Meanwhile, the filter element driving motor 444 can be started, and the circumferential gear 442 is driven to rotate through the driving gear 443, so that the filter element main body 3 is driven to rotate, the filter material 32 is alternated, the back flushing function is realized, the filter element is prevented from being blocked by fine impurities in some soup, and the service life is prolonged. Therefore, the materials in the left side pot cavity are completely exposed, the food can be conveniently eaten, the right side pot cavity is in a working state, when the right side heating and boiling time is up, the soup on the right side is conveyed to the left side pot cavity, and the food in the right side pot cavity can be eaten.

Because the problems of missing or excessive single side exist in the process of conveying the soup left and right, when the soup is insufficient, the water supplementing one-way valve 452 in the water supplementing device 45 is opened to supplement the soup; if the soup is too much, the soup solenoid valve 437 is closed, the quick-connection pipe 436 and the filter element still hold soup, and the drain solenoid valve 462 is opened to drain the excessive soup.

The foregoing description is only illustrative of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present invention.
