Description

Technical Field

[0001] This utility model relates to a gaiwan (lidded bowl) for brewing tea in a tea tasting machine. Background Technology

[0002] Currently, the common gaiwans used for brewing tea on tea tasting machines typically feature a coaxial and centrally located design for the hot water inlet and tea outlet. This structure causes hot water to directly and vertically impact the tea leaves piled at the bottom from the center of the top of the gaiwan. Due to the concentrated water flow, strong impact, and excessively high local temperature, bitter substances such as tea polyphenols and caffeine in the tea leaves are easily and rapidly extracted in excessive amounts, resulting in a significantly increased astringency in the brewed tea and severely affecting its flavor and taste. Furthermore, these gaiwans generally have a cylindrical filter embedded at the bottom tea outlet. During brewing, tea leaves tend to accumulate in large quantities within the filter, not only clogging the filter holes and reducing the efficiency of tea flow, but also exacerbating the continuous release of bitter substances due to the prolonged accumulation of tea leaves in the high-temperature zone, further degrading the quality of the tea.

[0003] Therefore, overcoming the aforementioned shortcomings has become an important issue that urgently needs to be addressed by those skilled in the art. Utility Model Content

[0004] This invention overcomes the shortcomings of the above-mentioned technology and provides a gaiwan for brewing tea in a tea tasting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gaiwan for brewing tea in a tea tasting machine includes a gaiwan body 1, a hot water inlet 2 with an upward-facing opening on the top edge of the gaiwan body 1, the lower wall of the hot water inlet 2 gradually extending from the outside to the inside of the gaiwan body 1 from top to bottom, a tea soup outlet 3 centrally located at the bottom of the gaiwan body 1, and a filter screen 4 covering the tea soup outlet 3 inside the gaiwan body 1.

[0007] Preferably, the main body 1 of the covered bowl includes a lid 11 and a bowl 12 that fit together. The side wall of the bowl 12 is provided with a flange 121 that extends gradually outward from bottom to top. The flange 121 is used to protrude from the edge of the lid 11 after the lid 11 covers the upper opening of the bowl 12 and together with the lid 11 forms the hot water inlet 2.

[0008] Preferably, the central portion of the filter 4 is higher than the surrounding edges, or the filter 4 gradually rises from the edges to the center.

[0009] Preferably, the filter 4 is hemispherical.

[0010] Preferably, the bottom of the gaiwan body 1 is also provided with a sealing component 5 surrounding the tea soup outlet 3, the sealing component 5 being used to contact and connect with the tea tasting machine.

[0011] Preferably, the sealing assembly 5 includes an elastic sealing ring 51, a first sealing element 52, and a second sealing element 53. The elastic sealing ring 51 is annular with a C-shaped cross-section, and the C-shaped opening of the elastic sealing ring 51 is engaged at the bottom opening of the lid bowl body 1. The first sealing element 52 is annular with a U-shaped cross-section and is engaged from bottom to top at the bottom opening of the lid bowl body 1 to press the elastic sealing ring 51 tightly against the outer bottom surface of the lid bowl body 1. The second sealing element 53 is inserted from top to bottom into the bottom opening of the lid bowl body 1. The second sealing element 53 includes a pressing part 531 that presses the elastic sealing ring 51 against the inner bottom surface of the gaiwan body 1. The pressing part 531 has a downwardly extending connecting part 532 in the center. The connecting part 532 is inserted into the bottom opening of the gaiwan body 1 and threadedly connected to the annular opening in the center of the first sealing element 52 so as to lock the first sealing element 52 and the second sealing element 53. The elastic sealing ring 51 is pressed against the bottom opening of the gaiwan body 1. The tea soup outlet 3 is located in the center of the connecting part 532. The filter screen 4 is fixed on the second sealing element 53.

[0012] Preferably, the bottom opening of the lid bowl body 1 is further provided with a first positioning notch 13, the elastic sealing ring 51 is provided with a first positioning protrusion 511 that corresponds to the position of the first positioning notch 13 and can form a concave-convex fit, the inner surface of the elastic sealing ring 51 is further provided with a second positioning notch 512, and the first sealing member 52 is provided with a second positioning protrusion 521 that corresponds to the position of the second positioning notch 512 and can form a concave-convex fit.

[0013] Preferably, the bottom of the covered bowl body 1 is provided with a plurality of circumferentially distributed, horizontally extending third positioning protrusions 6.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This gaiwan design, by offsetting the hot water inlet and placing a filter over the tea inlet, effectively avoids the problem of traditional gaiwan structures where concentrated hot water impacts the tea leaves, leading to bitterness. It also prevents tea leaves from accumulating in the filter at the tea inlet. Furthermore, the offset hot water inlet and the filter working together ensure the water flow thoroughly disperses the tea leaves, allowing for a more balanced mixing of hot water and tea leaves, resulting in a more balanced extraction of flavor compounds and ultimately enhancing the tea's taste.

[0023] The following embodiments further illustrate the features of this utility model and other related features in detail, so as to facilitate understanding by those skilled in the art:

[0024] like Figures 1 to 7 As shown, a gaiwan for brewing tea in a tea tasting machine includes a gaiwan body 1. The top edge of the gaiwan body 1 is provided with an upward-facing hot water inlet 2. The lower wall of the hot water inlet 2 gradually extends from the outside to the inside of the gaiwan body 1 from top to bottom. The bottom of the gaiwan body 1 is provided with a tea soup outlet 3 in the center. A filter screen 4 is provided inside the gaiwan body 1 to cover the tea soup outlet 3.

[0025] In this design, the tea infusion outlet 3 of the gaiwan is conventionally positioned at the bottom of the gaiwan body 1, while the hot water inlet 2 is offset at the top edge of the gaiwan body 1, with the lower wall of the hot water inlet 2 gradually extending inward from top to bottom. This way, when hot water enters the gaiwan body 1 through the hot water inlet 2, it is guided to flow downward along the wall of the gaiwan body 1, avoiding the vertical impact of hot water on the tea leaves at the bottom as in traditional gaiwans. This disperses the impact of the water flow on the tea leaves at the bottom of the gaiwan body 1, reducing the excessive and rapid extraction of bitter substances such as tea polyphenols and caffeine, thus lowering the astringency of the tea and enhancing its flavor. Furthermore, the filter 4 of the gaiwan body 1 covers the tea infusion outlet 3, preventing tea leaves inside the gaiwan body 1 from falling into the tea infusion outlet 3 and accumulating there, thus clogging the filter holes. At the same time, the hot water flowing down the wall of the gaiwan body 1 can easily form a vortex of water flow inside the gaiwan body 1. With the help of the filter screen 4 that intercepts the tea leaves outside the tea soup outlet 3, the water flow can disperse the tea leaves so that the hot water can be fully mixed with the tea leaves, thereby avoiding local high temperature and making the extraction of tea flavor substances more balanced, further improving the taste of the tea soup.

[0026] As described above, the gaiwan in this case, by offsetting the hot water inlet 2 and covering the tea outlet 3 with the filter 4, effectively avoids the problem of concentrated hot water impacting the tea leaves, which leads to bitterness in the tea soup, as is common in traditional gaiwan structures. It also effectively prevents tea leaves from accumulating in the filter within the tea outlet 3. Furthermore, the offset hot water inlet 2 and the filter 4 covering the tea outlet 3 work together to ensure the water flow fully disperses the tea leaves, allowing for thorough mixing of the hot water and tea leaves, resulting in a more balanced extraction of flavor compounds and further enhancing the taste of the tea soup.

[0027] like Figures 1 to 4 As shown, preferably, the main body 1 of the covered bowl includes a lid 11 and a bowl 12 that fit together. The side wall of the bowl 12 is provided with a flange 121 that extends gradually outward from bottom to top. The flange 121 is used to protrude from the edge of the lid 11 after the lid 11 covers the upper opening of the bowl 12 and together with the lid 11 forms the hot water inlet 2.

[0028] As described above, the main body 1 of this gaiwan includes a lid 11 and a bowl 12. A flange 121 is provided on the side wall of the bowl 12, extending gradually outwards from bottom to top. Thus, when the lid 11 is closed onto the opening of the bowl 12, the edge of the lid 11 and the flange 121 form the hot water inlet 2. Hot water enters the hot water inlet 2 and flows along the flange 121 towards the bottom of the bowl 12, preventing hot water from directly impacting the tea leaves and causing bitterness. Furthermore, since the hot water inlet 2 is formed by the lid 11 and the flange 121, air can also freely enter and exit the gaiwan main body 1 through the hot water inlet 2, maintaining breathability inside the gaiwan main body 1 and preventing the tea leaves from becoming stale inside.

[0029] like Figure 3 and Figure 4 As shown, preferably, the central part of the filter 4 is higher than the surrounding edges, or the filter 4 gradually rises from the edges to the center. In this way, the shape of the filter 4, which is higher in the center and lower around the edges, allows the tea leaves to automatically slide to the edge of the filter by gravity, avoiding the accumulation of tea leaves in the center of the filter 4 during the brewing process. This not only prevents the tea leaves from clogging the filter 4 and affecting the flow efficiency of the tea soup, but also makes the tea leaves more evenly distributed, allowing the hot water to come into more thorough and gentle contact with the tea leaves, thereby reducing the excessive precipitation of bitter substances caused by local high temperature.

[0030] like Figure 3 and Figure 4 As shown, preferably, the filter screen 4 is hemispherical. In this way, designing the filter screen 4 as a hemispherical shape can make the surface of the filter screen 4 streamlined, so that the tea leaves can unfold more freely when they come into contact with the filter screen 4.

[0031] like Figures 1 to 5As shown, preferably, the bottom of the gaiwan body 1 is also provided with a sealing component 5 surrounding the tea soup outlet 3, the sealing component 5 being used to contact and connect with the tea tasting machine.

[0032] For some gaiwans made of glass or ceramic, due to the inherent shrinkage rate differences during the firing process and processing limitations, the size differences between individual gaiwans made of these materials are often quite large. Therefore, when these gaiwans come into contact with a tea tasting machine, they are prone to inadequate sealing, leading to leakage of tea.

[0033] The gaiwan in this case has a sealing component 5 set around the tea soup outlet 3 at the bottom of the gaiwan body 1. The sealing component 5 serves as the medium for contact and connection between the gaiwan body 1 and the tea tasting machine, which can effectively eliminate the impact of changes in the individual size of the gaiwan body 1 on the sealing performance.

[0034] like Figures 1 to 5 As shown, preferably, the sealing assembly 5 includes an elastic sealing ring 51, a first sealing element 52, and a second sealing element 53. The elastic sealing ring 51 is annular with a C-shaped cross-section, and the C-shaped opening of the elastic sealing ring 51 is engaged at the bottom opening of the lid bowl body 1. The first sealing element 52 is annular with a U-shaped cross-section and is engaged from bottom to top at the bottom opening of the lid bowl body 1 to press the elastic sealing ring 51 tightly against the outer bottom surface of the lid bowl body 1. The second sealing element 53 is inserted from top to bottom into the bottom opening of the lid bowl body 1. The second sealing element 53 includes a pressing part 531 that presses the elastic sealing ring 51 against the inner bottom surface of the gaiwan body 1. The pressing part 531 has a downwardly extending connecting part 532 in the center. The connecting part 532 is inserted into the bottom opening of the gaiwan body 1 and threadedly connected to the annular opening in the center of the first sealing element 52 so as to lock the first sealing element 52 and the second sealing element 53. The elastic sealing ring 51 is pressed against the bottom opening of the gaiwan body 1. The tea soup outlet 3 is located in the center of the connecting part 532. The filter screen 4 is fixed on the second sealing element 53.

[0035] As described above, the sealing assembly 5 in this case includes an elastic sealing ring 51, a first sealing member 52, and a second sealing member 53. The elastic sealing ring 51 is engaged at the bottom opening of the lid bowl body 1, and the U-shaped first sealing member 52 is engaged from bottom to top at the bottom of the lid bowl body 1, thus pressing the elastic sealing ring 51 tightly at the bottom opening of the lid bowl body 1 from bottom to top. The second sealing member 53 is inserted from top to bottom into the bottom opening of the lid bowl body 1, and the second sealing member 53 is provided with a pressing part 531 and a connecting part 532. The pressing part 531 can be used to press the elastic sealing ring from top to bottom. The first sealing ring 51 is pressed firmly against the bottom of the gaiwan body 1. Then, the first sealing ring 52 and the second sealing ring 53 are locked together by connecting the connecting part 532 to the annular opening thread in the center of the first sealing ring 52. This provides both upward and downward pressure to the elastic sealing ring 51, ensuring a tight fit between the elastic sealing ring 51 and the gaiwan body 1. This counteracts dimensional variations caused by individual differences in the gaiwan body 1, allowing the elastic sealing ring 51 to effectively seal the bottom opening of the gaiwan body 1. The tea soup flows out from the tea soup outlet 3 in the center of the connecting part 532. The first sealing ring 52, located at the bottom of the gaiwan body 1, can also serve as a dimensionally stable intermediate component for sealing connection with the tea tasting machine. This eliminates the impact of dimensional fluctuations in the shape of the gaiwan body 1 on the seal between it and the tea tasting machine.

[0036] Specifically, the first sealing element 52 and the second sealing element 53 are both made of plastic, or the first sealing element 52 and the second sealing element 53 are both made of stainless steel, and the elastic sealing ring 51 is a silicone sealing ring.

[0037] like Figure 4 and Figure 5 As shown, preferably, the bottom opening of the lid bowl body 1 is also provided with a first positioning notch 13, the elastic sealing ring 51 is provided with a first positioning protrusion 511 that corresponds to the position of the first positioning notch 13 and can form a concave-convex fit, the inner surface of the elastic sealing ring 51 is also provided with a second positioning notch 512, and the first sealing member 52 is provided with a second positioning protrusion 521 that corresponds to the position of the second positioning notch 512 and can form a concave-convex fit.

[0038] As described above, the first positioning notch 13 and the first positioning protrusion 511 can lock the relative position of the elastic sealing ring 51 and the lid body 1. The second positioning notch 512 and the second positioning protrusion 521 can lock the relative position of the first sealing element 52 and the elastic sealing ring 51. This can prevent the first sealing element 52 and the second sealing element 53 from rotating relative to each other during the threaded connection process and thus prevent the elastic sealing ring 51 from moving relative to the lid body 1 during the threaded connection process, which would cause wrinkles in the elastic sealing ring 51 and affect the sealing effect.

[0039] like Figures 1 to 4 As shown, preferably, the bottom of the gaiwan body 1 is provided with several circumferentially distributed, horizontally extending third positioning protrusions 6. In this way, by setting positioning grooves on the tea tasting machine that correspond one-to-one with the third positioning protrusions 6, the position and angle of the gaiwan body 1 can be fixed when connected to the tea tasting machine, so that the hot water inlet 2 of the gaiwan body 1 can be accurately aligned with the hot water outlet of the tea tasting machine.

[0040] Specifically, the third positioning protrusion 6 is disposed on the outer wall of the first sealing member 52. Since the relative position of the first sealing member 52 and the gaiwan body 1 is determined, the third positioning protrusion 6 can be disposed on the first sealing member 52 to indirectly lock the relative position of the third positioning protrusion 6 and the hot water inlet 2, so that the hot water inlet 2 and the hot water outlet can be aligned when the tea tasting machine is connected and positioned through the third positioning protrusion 6.

[0041] As stated above, this case protects a gaiwan (lidded bowl) used for brewing tea in a tea tasting machine, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
