Description

Technical Field

[0001] The invention relates to a tea-boiling and tea-making utensil, in particular to a tea-boiling and tea-making pot. Background Art

[0002] Drinking tea has a long history. my country's tea drinking habits have gone through the methods of boiling tea and brewing tea. To this day, some teas are still boiled, and some are brewed. For example, black tea and Pu'er tea are boiled. Green tea, white tea, black tea, and Tieguanyin are brewed. This is based on the dissolution characteristics of the active ingredients in tea in aqueous solution. The active ingredients in black tea and Pu'er tea are difficult to dissolve by brewing tea, while green tea, white tea, black tea, and Tieguanyin can achieve the purpose of dissolving the active ingredients such as tea polyphenols in tea by brewing tea.

[0003] Drinking tea is no longer just a need to replenish water and quench thirst. More and more consumers believe that drinking tea is good for health. Drinking tea can obtain beneficial active ingredients such as antioxidant tea polyphenols. However, the sanitary quality of tea has caused many consumers and scholars to worry. According to public literature, there is a risk of contamination with harmful microorganisms during tea processing. These microorganisms mainly include enteric infection bacteria such as Escherichia coli and Salmonella. The current situation of harmful microbial contamination in tea in my country is not optimistic. According to the test results of the United States and Japan on my country's exported tea, more than 90% exceeded the standard [Chen Zongmao. Problems and Countermeasures Facing my country's Tea Sanitation Quality [J]. Tea Industry Bulletin 2001, 23 (1): 7-10]. In view of the sanitary status of tea, all tea consumers adopt the method of washing tea first and then boiling or brewing tea. However, the existing tea washing process is to rinse the tea with hot water, which is difficult to achieve the purpose of sterilization. This is because the water temperature of hot water for brewing tea is usually only about 90°C. The sterilization effect of rinsing the tea with hot water at about 90°C is very limited. The sterilization effect of boiling tea is better than rinsing with hot water. However, it is inconvenient to sterilize the existing tea-making utensils by boiling tea. Summary of the invention

[0004] Aiming at the defects of existing tea-making utensils, the task of the present invention is to provide a tea-making utensil, which is also suitable for making tea, and a tea-making pot, so as to improve the sanitary quality of drinking tea soup and improve the positive effect of the bioavailability of tea leaves.

[0005] Technical solution for realizing the present invention

[0006] A teapot for boiling tea, comprising a glass teapot, a pot cover, a handle, a bolt for fixing the handle, a rotating basket, a rotating basket, a teapot hoop, a pot bottom plate, a film electric heating plate, an annular sealing gasket, a rotating basket shaft, a mechanical seal, a mechanical seal upper cover plate, a mechanical seal bottom sealing plate, a bottom sealing plate locking bolt, an electrical connection pin, a conductive tube, a heat-insulating felt, a base plate locking bolt, a base shell, a knob switch, a reducer shaft, a coupling sleeve, an electrical connection pin seat, a pot fulcrum, a reduction motor, a pot bottom plate, and a bottom plate locking screw;

[0007] For the convenience of operation, a teapot for boiling tea is divided into two major parts, a pot holder and a pot stand.

[0008] When boiling or brewing tea, hold the pot and sit on the pot stand. When taking tea, lift the pot and leave the pot stand.

[0009] The pot seat is composed of a conductive tube, a seat shell, a knob switch, a reducer shaft, a coupling sleeve, a power pin seat, a pot support, a reducer motor, a pot seat bottom plate, and a bottom plate locking screw;

[0010] The teapot holder comprises a glass teacup, a pouring spout of the glass teacup, a pot lid, a handle, a bolt for fixing the handle, a rotating basket, a rotating basket, a teacup clamp, a pot bottom plate, a film heating plate, an annular sealing gasket, an insulating felt, a rotating basket shaft, a mechanical seal, a mechanical seal upper cover plate, a mechanical seal bottom sealing plate, a bottom sealing plate locking bolt, a power connection pin, 6 base plate locking bolts, a dovetail wedge of the pot bottom plate, a mechanical seal mounting hole of the pot bottom plate, 6 internal threaded support tubes near the outer circle of the film heating plate, an electric heating film of the film heating plate, a mechanical seal mounting hole of the film heating plate, a power connection pin, an internal threaded support tube, and a stainless steel substrate.

[0011] Among them, the glass teacup is clamped by a teacup clamp, and the handle is fixed by a bolt passing through the teacup clamp, and then through the handle and locked with the handle. The lower end of the handle is wedged and fixed by a dovetail wedge on the bottom plate of the pot.

[0012] The thin film electric heating plate is placed at the bottom of the glass teacup. There is an annular sealing gasket between the thin film electric heating plate and the inner bending edge of the bottom of the glass teacup. Below the inner bending edge is the pot bottom plate. The internal threaded support tube of the thin film electric heating plate passes through 6 base plate locking bolt holes arranged near the outer circle of the pot bottom plate and is locked by 6 base plate locking bolts. After the 6 base plate locking bolts lock the thin film electric heating plate and the pot bottom plate, the annular sealing gasket is compressed, and a water sealing structure is formed between the inner bending edge of the bottom of the glass teacup and the annular sealing gasket, and between the annular sealing gasket and the pot bottom plate.

[0013] The annular sealing gasket is made of silicone rubber, which has outstanding heat resistance, can work for a long time at 180°C, can withstand hundreds of hours at 200°C, or can still maintain elasticity for longer periods of time, and can instantly withstand high temperatures above 300°C. Silicone rubber is chemically inactive and non-toxic, and is widely used in sealing food containers and in the medical field.

[0014] The rotating basket shaft is installed in the inner circular hole of the mechanical seal;

[0015] The mechanical seal is installed in the mechanical seal installation hole of the thin film electric heating plate and the center installation hole of the kettle bottom plate, and is clamped by the mechanical seal upper cover plate at the top and the mechanical seal bottom sealing plate at the bottom, and is locked and fixed by 4 bottom sealing plate locking bolts.

[0016] The mechanical seal is a shaft sealing device that is perpendicular to the shaft and slides relatively to the end surface, which is kept in close contact under the action of fluid pressure and the elastic force of the compensation mechanism, and is equipped with an auxiliary seal to achieve dynamic and static leakage prevention.

[0017] Usually mechanical seals are composed of static rings, dynamic rings, elastic elements, spring seats, set screws, rotating ring auxiliary seals and static ring auxiliary seals.

[0018] Mechanical seals are mature mechanical products, and the specifications and models that match the rotating shaft diameter can be selected from the product series supplied on the market. In this technical solution, the mechanical seal allows the rotating basket shaft to maintain water sealing in a rotating state or a stationary state, thereby preventing the aqueous solution in the glass teacup from leaking.

[0019] The film electric heating plate comprises a stainless steel substrate, an electric heating film, a mechanical seal mounting hole, an electrical connection pin, and an internally threaded support tube, wherein six internally threaded support tubes are arranged close to the outer circle;

[0020] The stainless steel substrate is the bearing structure of the electric heating film;

[0021] The electric heating film comprises a ceramic insulating layer, a conductive heating layer and a ceramic sealing layer;

[0022] The ceramic insulating layer is attached to the surface of the stainless steel substrate, the conductive heating layer is attached to the surface of the ceramic insulating layer, the surface of the conductive heating layer is covered with a ceramic sealing layer, the conductive heating layer is placed between the ceramic insulating layer and the ceramic sealing layer, the ceramic insulating layer and the ceramic sealing layer seal the conductive heating layer, keep the conductive heating layer isolated from the air, avoid oxidation, and make the performance of the conductive heating layer durable. The ceramic insulating layer and the ceramic sealing layer are both aluminum oxide nanomaterials.

[0023] The conductive heating layer is a conductive heating layer made of graphene, carbon nanotubes and conductive carbon black; or a conductive heating layer made of a mixture of graphene and carbon nanotubes, or a mixture of carbon nanotubes and conductive carbon black; or a conductive heating layer made of a mixture of graphene, carbon nanotubes and conductive carbon black.

[0024] The conductive heating layer is made of graphene, carbon nanotubes and conductive carbon black. It has a rapid thermal response when powered on, can heat up quickly, has small thermal inertia, and cools down quickly. The electric heating film and the stainless steel substrate have good thermal conductivity. The heat generated by the electric heating film can be quickly conducted through the stainless steel substrate, causing the aqueous solution in the glass teacup to heat up quickly. It has small thermal inertia, and the tea in the glass teacup cools down quickly, which is beneficial to maintaining the flavor of the tea.

[0025] The electrical connection pins are prefabricated on the surface of the conductive heating layer and fixed by conductive glue;

[0026] The six internal thread support tubes of the thin film electric heating plate pass through the six base plate locking bolt holes near the outer circle of the bottom plate of the kettle, and are locked and fixed by the six base plate locking bolts;

[0027] Two power connection pins of the thin film electric heating plate pass through the power connection pin holes of the kettle bottom plate, and the power connection pin ends extend from the kettle bottom plate.

[0028] The thermal insulation felt is installed between the film electric heating plate and the bottom plate of the pot, which plays a role in isolating the heat generated by the electric heating film from being conducted to the bottom plate of the pot, thereby improving the heating efficiency of the film electric heating plate on the aqueous solution in the glass teacup and preventing the bottom plate from being heated and causing the temperature to rise.

[0029] The thermal insulation felt is selected from aluminum silicate felt and silicon dioxide aerogel felt.

[0030] Silica aerogel is mainly composed of silicon dioxide, which can withstand most acid and alkali environments except hydrofluoric acid for a long time without decomposition or change. It is an excellent nanoporous amorphous solid material with a porosity of 80-99.8%, a pore size of 1-100 nanometers, and a specific surface area of ​​200-1000m 2 / g, density is only 3kg / m 3 , room temperature thermal conductivity ≤ 0.012W / mK, it is an excellent thermal insulation material;

[0031] Aluminum silicate material has high temperature resistance, and the maximum operating temperature can reach 1300℃. It has low thermal conductivity, and the room temperature thermal conductivity coefficient is ≤0.035W / mK; it is light in weight, and the density of the dry-processed product is 80~100kg / m 3 , has good chemical stability.

[0032] The rotating basket frame shaft has a rotating basket frame installed on its upper end. When the rotating basket frame shaft rotates, the rotating basket frame rotates accordingly. When the rotating basket frame rotates, the rotating basket sleeved on the rotating basket frame rotates accordingly.

[0033] The seat shell is radially installed with a knob switch, the axial center of the seat shell is the reducer shaft, the upper end of the reducer shaft is fixed with a coupling sleeve, an electrical connection pin seat is arranged on the left side of the coupling sleeve, and the electrical connection pin seat includes two conductive tubes, four pot support points are evenly distributed on the inner circular wall of the seat shell, and the reduction motor is located below the reducer shaft, and the bottom plate of the pot seat is locked by the bottom plate locking screws.

[0034] When the pot bottom plate is seated on four pot support points evenly distributed on the inner circular wall of the seat shell, the rotating basket frame shaft is inserted into the coupling sleeve;

[0035] The coupling sleeve is made of rubber, and the high elasticity of rubber can be reversibly deformed to form an elastic connection between the coupling sleeve and the rotating basket shaft. When the coupling sleeve rotates, the rotating basket shaft rotates accordingly. The coupling sleeve and the rotating basket shaft are elastically connected, which is convenient for connection and separation.

[0036] When the reduction motor is working, the reducer shaft rotates, and when the reducer shaft rotates, the coupling sleeve fixed to the reducer shaft rotates accordingly, and when the coupling sleeve rotates, the rotating basket frame shaft rotates accordingly, and when the rotating basket frame shaft rotates, the rotating basket frame rotates accordingly, and when the rotating basket frame rotates, the rotating basket seated on the rotating basket frame rotates accordingly;

[0037] The reduction motor is composed of a speed regulating motor and a reduction box. The rotation speed of the rotating basket can be controlled by adjusting the speed of the speed regulating motor.

[0038] When the kettle bottom plate is seated on the four evenly distributed kettle support points on the inner circular wall of the base shell, the power plug end extending from the kettle bottom plate is inserted into the conductive tube on the power plug seat, and the conductive tube is connected to the power supply from the outside through the knob switch (the connection circuit is not shown in the figure). The knob switch controls the working state of the reduction motor and the thin film electric heating plate.

[0039] Tea making and brewing operations:

[0040] Put the tea leaves into the rotating basket on the rotating basket frame, put an appropriate amount of pure water into the glass teacup, cover the pot lid, start the reduction motor through the knob switch, turn on the power of the thin film heating plate, the pure water in the glass teacup will heat up rapidly, the rotating basket will rotate, and the tea leaves in the rotating basket will be disturbed in the pure water. As the rotating speed of the rotating basket increases, the tea leaves in the rotating basket and the pure water in the glass teacup will form a flushing and shearing effect.

[0041] According to the habit of making tea, the tea leaves need to be washed first, then brewed, to remove the dust and debris in the tea leaves, making the tea soup more hygienic and refreshing. The tea leaves in the rotating basket and the pure water in the glass teacup form a flushing and shearing effect, which is conducive to rapid cleaning.

[0042] After washing the tea, pour out the washing water, add pure water again, start the reduction motor again through the knob switch, turn on the power of the thin film electric heating plate, the pure water in the glass teacup heats up quickly, the basket rotates, and the tea leaves in the basket are disturbed in the pure water. As the basket rotates faster, the washed tea leaves in the basket and the pure water in the glass teacup form a scouring and shearing effect. The scouring and shearing effect between the washed tea leaves in the basket and the pure water in the glass teacup is conducive to the rapid dissolution of tea polyphenols, tea polysaccharides and other water-soluble components in the tea leaves. When making tea, you can visually observe the color of the dissolved tea soup through the glass teacup to judge the concentration of the tea soup, and choose the appropriate tea soup concentration according to the habits of tea drinkers.

[0043] The flushing and shearing effects formed by the tea leaves in the rotating basket and the pure water in the glass teacup are beneficial to the more thorough dissolution of water-soluble components such as tea polyphenols and tea polysaccharides in the tea leaves, thereby improving the bioavailability of the tea leaves.

[0044] Depending on the type of tea, you can choose to brew the tea or boil it. Black tea and Pu'er tea are boiled, while green tea, white tea, black tea and Tieguanyin tea are suitable for brewing.

[0045] For brewing tea, the film heating plate can reach the appropriate tea soup concentration in a short working time. For boiling tea, the film heating plate needs to work for a long time to reach the appropriate tea soup concentration. The working time of the film heating plate can be further selected according to the quality of the tea. The tenderer the tea, the shorter the working time of the film heating plate should be, and the older the tea, the longer the working time of the film heating plate should be.

[0046] Positive significance of the teapot for boiling tea

[0047] The invention discloses a tea-brewing kettle, which adopts the thin-film electric heating plate fast response heating technology and the rotating basket rotation technology, so that the tea leaves in the rotating basket form a flushing and shearing effect with the pure water in the glass teacup, and are heated and boiled or heated and brewed simultaneously, thereby improving the sanitary quality of the drinking tea soup and having the positive effect of improving the bioavailability of the tea leaves.
