The pressure cannot be automatically balanced when tea is poured, the cover and the tea bowl need to be manually staggered, which is inconvenient to operate, and the staggered range affects the water output, and insufficient experience can cause slow or fast water output; 2. Since the periphery of the tea bowl is a uniform round opening, the water output range is wide, and it is difficult to connect to a small-diameter tea cup; 3. The stability of placement is poor, it is easy to tip over, and the tea table is easy to slide when there is water accumulation; 4. There is no filter screen, and the tea is easily poured out with the tea water, which depends on the appropriate gap between the cover and the tea bowl.

[0003] In order to achieve the purpose of filtering tea leaves, the existing methods are divided into two kinds, one is to pour tea into a container with a separate filter screen through a cover bowl type tea making device, which not only increases an operation process, but also reduces the tea water temperature during the filtering process, which may affect the drinking taste. The second is to set a filter screen in the container, such as a portable thermos cup or a teapot with a filter screen inside, the tea leaves are usually located below the filter screen, and when replacing the tea leaves, not only the filter screen needs to be taken out and washed, but also the tea leaves in the container need to be repeatedly washed, which is not fast enough.

[0004] In order to balance the pressure, the existing method is to open a gas hole on the cover of the tea making container, but in the process of pouring tea, in order to prevent the cover from slipping due to tilting, the cover needs to be pressed by hand, and the water vapor emitted from the gas hole on the cover is easy to scald the user.

[0005] In addition, the existing tea making appliances are mostly made of ceramic or glass materials, and the heat insulation effect is poor. UTILITY MODEL CONTENTS

[0024] Referring to the drawings, Figures 1-3 In the structure of one specific embodiment of the utility model, the tea making container, the lid and the filter are included, the filter is nested in the inside of the tea making container and is pressed by the lid, the upper edge of the tea making container is provided with a water outlet and an air pressure balance opening, the inner wall of the tea making container is provided with an inwardly extending anti-spilling support ring, the filter includes a ring-shaped stainless steel frame and a filter screen installed on the stainless steel frame and recessed downward, the lid includes a cover plate and a pressing ring below the surface of the cover plate, the pressing ring is provided with an air permeation seam corresponding to the air pressure balance opening, and the stainless steel frame is clamped between the pressing ring and the anti-spilling support ring.

[0025] The water outlet and the air pressure balance opening are oppositely arranged on the tea making container. When pouring tea, the water outlet is below and the air pressure balance opening is above, so that the tea water flows out smoothly. When holding the tea making container and pressing the lid, the air pressure balance opening is prevented from overflowing water vapor to scald.

[0026] The length of the air permeable seam is 1 / 4 of the length of the compression ring. The air permeable seam with a proper length can facilitate the formation of an air flow channel in communication with the outside on the basis of ensuring that the compression ring can compress the stainless steel frame.

[0027] The height of the compression ring is greater than the distance between the spill-proof supporting ring and the upper edge of the tea-making container, and the air pressure balancing port is higher than the spill-proof supporting ring. The compression ring is sleeved on the inner side of the inner wall of the tea-making container. The gap between the compression ring and the inner wall of the tea-making container is 0.15mm-0.30mm; the diameter of the tea-making container is greater than the height of the tea-making container, and the ratio of the distance between the spill-proof supporting ring and the top of the tea-making container to the distance between the spill-proof supporting ring and the bottom of the tea-making container is 1 / 5. When the lid covers the tea-making container, the compression ring can compress the stainless steel frame of the filter to avoid shaking. The tea-making container is flat, which facilitates holding the bottom of the tea-making container and the top of the lid with one hand.

[0028] The height of the spill-proof supporting ring from the top of the tea-making container is 7-8mm, the height of the spill-proof supporting ring from the bottom of the tea-making container is 35-40mm, and the diameter of the thinnest position of the tea-making container is greater than 50mm.

[0029] The air pressure balancing port is a semicircular notch, and the cross-sectional area of the air pressure balancing port is 7-15mm 2 .

[0030] The water outlet is a V-shaped notch, and the stainless steel frame is located between the highest point and the lowest point of the water outlet. The V-shaped notch of the water outlet can control the water flow range, facilitating the introduction into a small-caliber tea cup.

[0031] The middle region of the cover plate is concave downward, forming a rim with an upwardly protruding edge.

[0032] The spill-proof supporting ring is provided with a notch matching the shape of the water outlet. The notch can ensure that the tea water outside the filter flows smoothly from the water outlet.

[0033] The tea-making container and the lid are both made of heat-insulating transparent material, such as PCTG material. This can avoid burning hands during holding and maintain the internal temperature.

[0034] The side wall of the tea-making container gradually thickens from top to bottom; the bottom of the tea-making container is concave upward, thereby forming a bottom edge supporting the posture of the tea-making container. This can lower the center of gravity, increase the stability of placement, and avoid water sliding caused by pouring and water accumulation.

[0035] In use, according to Figure 1The utility model discloses a filterable tea making container, which comprises a filterable tea making container body, a filterable tea making container cover and a filter, wherein the filterable tea making container body is provided with a filterable tea making container cavity, and the filterable tea making container cover is provided with a filterable tea making container cover cavity.

[0036] In addition, the anti-splashing supporting ring not only supports the stainless steel frame of the filter, but also forms an anti-splashing edge in the inner cavity of the tea making container, which blocks the oscillating water flow caused by the water flow hitting the wall of the container, thereby preventing tea overflow caused by vibration.

[0037] The above description is only used to propose the technical scheme of the utility model, and is not used to limit the utility model itself.
