Description

Technical Field

[0001] The utility model relates to the technical field of tea making machines, in particular to a novel intelligent tea making machine integrating extraction and brewing. Background Art

[0002] During the tea brewing process, when the tea barrel receives hot water from the tea brewing machine for hot brewing, in order to improve the tea leaf extraction efficiency and tea soup uniformity, attempts have been made to use a stirring mechanism on the top of the tea barrel to rotate and stir, or to directly use the water flow from the top to flush. However, both methods have exposed certain limitations in practice: while the stirring method can promote the mixing of tea and water, it can easily cause the tea leaves to break or become entangled in the tea filter, increasing the complexity of subsequent cleaning work, including cleaning the top cover, tea barrel, and tea filter; and while the flushing method can effectively promote the mixing of the tea soup during the initial water intake, its flushing force is insufficient when faced with a large amount of tea leaves. Once the water volume reaches the standard, the flushing effect ends, and the tea soup returns to static soaking, which may affect the full release of the tea leaves.

[0003] In view of the above technical bottlenecks, those skilled in the art are actively seeking innovative solutions. For example, the cold extraction and hot brewing dual system and capsule tea machine disclosed in Chinese patent CN214856055U integrates the cold extraction and hot brewing functions into the same device, achieving the diversification and convenience of tea making and improving the extraction efficiency to a certain extent. However, this solution still fails to fully solve the problems existing in the traditional tea brewing method, such as cumbersome operation, insufficient water temperature control accuracy, insufficient tea brewing quantity, and tea brewing efficiency that needs to be improved. Especially in the fast-paced modern business environment, it is difficult to meet customers' demands for quick response, high-quality tea soup and strict hygiene standards. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies of the existing technology and provide a new type of integrated intelligent tea brewing machine for improving tea brewing efficiency, ensuring the quality of tea soup, and simplifying the operating process to meet the high standards required in modern commercial applications.

[0005] The technical solutions adopted in this utility model are as follows:

[0006] A new type of intelligent tea brewing machine that can extract and brew tea all in one, comprising the following devices:

[0007] The hot water device is located at the back of the tea maker and includes a main inlet valve and a heating device. One end of the main inlet valve is connected to the water inlet, and the other end of the main inlet valve is connected to the heating device, which is used to provide hot water to the tea maker;

[0008] The tea brewing device is located at the top of the tea brewing machine and includes a tea brewing bucket, an ultrasonic extraction unit, and a water pump. The water inlet end of the tea brewing bucket is connected to the heating device through a hot water outlet valve. The ultrasonic extraction unit is arranged at the bottom of the tea brewing bucket. The water outlet end of the tea brewing bucket is connected to the water pump through a circulation solenoid valve. The water pump sends the circulating water to the tea brewing bucket. The tea brewing device is provided with three working modes:

[0009] The hot water brewing mode. Through the hot water outlet valve, after the tea brewing bucket performs hot water brewing, the tea outlet solenoid valve is opened.

[0010] The ultrasonic extraction mode. Through the mixing valve, low-temperature hot water is obtained. After the tea brewing bucket performs low-temperature extraction by the ultrasonic extraction unit, the tea outlet solenoid valve is opened.

[0011] The circulating brewing mode. Through the hot water outlet valve, the circulation solenoid valve, and the water pump, after the tea brewing bucket performs hot water circulating brewing, the tea outlet solenoid valve is opened.

[0012] The tea outlet device is located at the lower part of the tea brewing machine and includes a tea outlet solenoid valve and a tea receiving bucket. One end of the tea outlet solenoid valve is connected to the water pump, and the other end of the tea solenoid valve is connected to the tea receiving bucket.

[0013] Through the addition of an ultrasonic extraction unit, a hot water device, the addition of a circulating brewing mode, and the provision of a dedicated tea outlet device, this technical solution realizes the comprehensive optimization of the tea brewing process. Specifically, through the independently set hot water device, the flexibility of water temperature control is enhanced, and the water temperature range can be adjusted according to needs. Whether it is high-temperature brewing to stimulate the aroma of tea leaves or low-temperature extraction to retain nutrients, it can be easily handled. Through the ability to accurately control the temperature, the tea brewing time can be significantly shortened, improving the overall tea brewing efficiency. It is suitable for commercial occasions such as milk tea shops and tea houses that need to quickly respond to customer needs, and can effectively shorten the morning opening preparation time of the store or the tea brewing waiting time during daily operations by about 30% to 40%, significantly improving the operation efficiency. On the basis of traditional hot water brewing, the addition of a circulating brewing mode and an ultrasonic extraction mode makes the tea brewing process more diverse and refined. Through the cooperation of the water pump and the circulation solenoid valve in the circulating brewing, the water in the tea brewing bucket forms a circulating flow for the full infiltration of tea leaves and the uniform mixing of tea soup, and the number of circulations and time can also be adjusted according to the tea leaf characteristics and brewing requirements to achieve precise control of the tea soup taste. The flexible switching of the three brewing modes meets the brewing requirements of different tea leaves. The provision of a dedicated tea outlet device, including a tea receiving bucket, is a direct manifestation of the tea brewing machine's emphasis on user experience and hygiene and safety. It not only ensures the quick discharge of tea soup, but also effectively avoids the pollution problem of tea soup during the discharge process through the independent tea receiving bucket, ensuring the purity and hygiene of the tea soup.

[0014] In addition, according to the above-mentioned new extraction and brewing integrated intelligent tea brewing machine of the present utility model, it can also have the following additional technical features:

[0015] According to an embodiment of the present utility model, the tea brewing machine further includes:

[0016] A control device, located at the back of the tea brewing machine, includes a controller which is respectively connected to a hot water device, a tea brewing device, a tea discharging device, an alarm device and a display device;

[0017] An alarm device, located at the top of the tea brewing machine, includes an alarm indicator light and a buzzer, and is used to remind the user of abnormal tea brewing;

[0018] A display device, located at the upper part of the tea brewing machine, includes a touch screen and is used to display and input tea brewing information.

[0019] In this technical solution, tea brewing information is set through the touch screen, and the controller receives the signal and starts the hot water device to heat to the set temperature; after the water heating is completed, the controller controls the hot water to flow into the tea brewing device; during the tea brewing process, if an abnormality occurs (such as too high water temperature), the alarm device (indicator light and buzzer) is immediately started to remind the user; after the tea brewing is completed, the controller starts the tea discharging device, and the tea soup flows into the tea receiving container; during the whole process, the touch screen real-time displays the tea brewing state, and the user can view or adjust the settings at any time.

[0020] According to an embodiment of the present utility model, the heating device further includes a quick heater. One end of the heating water tank is connected to the main inlet valve, the other end of the heating water tank is connected to the quick heater, and the quick heater is connected to the water inlet end of the tea brewing barrel through a hot water outlet valve; the heating water tank is used to heat the high-temperature water temperature to the set temperature, and the quick heater is used to heat the water temperature to the temperature required for tea brewing.

[0021] In this technical solution, when the main inlet valve is opened, the normal temperature water enters the heating water tank through the pipeline. The heating element (such as an electric heating tube) in the heating water tank starts to work, and heats the high-temperature water temperature to the set temperature. The set temperature is preset to reduce the heating burden of the subsequent quick heater and improve the overall energy efficiency; in the preliminary heating stage, in the heating water tank, the water is continuously heated to the set temperature. Once this temperature is reached, the heating water tank will stop heating or reduce the heating power to keep the water temperature stable; the heated water flows through the pipeline to the quick heater; in the final heating stage, the quick heater receives the high-temperature water from the heating water tank and immediately starts to heat. The heating element heater in the quick heater quickly raises the water temperature to the temperature required for tea brewing, and the temperature range is set according to the brewing requirements of different teas to ensure that the tea can fully release its aroma; in the water outlet stage: when the water temperature reaches the temperature required for tea brewing, the quick heater sends the heated water into the water inlet end of the tea brewing barrel through the hot water outlet valve.

[0022] According to an embodiment of the present utility model, the heating device further includes a mixing valve, one end of which is connected to the main inlet valve and the other end of which is connected to the hot water tank, and low-temperature water is obtained by proportionally exchanging high-temperature water and normal temperature water.

[0023] This technical solution obtains hot water at the required temperature by mixing high-temperature water and normal-temperature water. Compared with directly heating normal-temperature water to the target temperature, the water flow rate of the outlet is more stable. By adjusting the flow rate ratio of high-temperature water and normal-temperature water, the water temperature after mixing can be precisely controlled. Low-temperature water is mainly used for soaking. Different temperatures of water can be used for soaking: cold soaking is at 10 - 20°C, warm soaking is at 30 - 60°C, and hot soaking is at about 80°C.

[0024] According to an embodiment of the present utility model, the tea brewing bucket is provided with one-way interfaces that cooperate with the tea brewing machine. The water inlet end and the water outlet end of the tea brewing bucket are respectively connected to the two one-way interfaces. When the tea brewing bucket comes into contact with the tea brewing machine, the one-way interfaces are opened.

[0025] In this technical solution, when the tea brewing bucket comes into contact with the tea brewing machine, the one-way interfaces will automatically open, allowing water to flow unobstructedly into and out of the tea brewing bucket, avoiding problems such as water leakage and seepage that may exist in traditional tea brewing methods, and improving the efficiency of tea brewing.

[0026] According to an embodiment of the present utility model, the three working modes set by the tea brewing device are allowed to be used in combination.

[0027] In this technical solution: (1) The hot water brewing mode is applicable to most teas that require high-temperature brewing. By directly opening the hot water outlet valve, the hot water that has reached the preset temperature (such as 85 - 95 °C) in the heating device is quickly injected into the tea brewing bucket for traditional hot water brewing. After brewing is completed, the tea outlet solenoid valve is opened to pour the brewed tea soup into the tea container; the advantage of the hot water brewing mode is that it is simple and direct, can quickly complete the brewing process, and is suitable for teas with high water temperature requirements. (2) The ultrasonic extraction brewing mode uses the ultrasonic extraction unit to extract tea components under low-temperature conditions; through the mixing valve, high-temperature water and normal-temperature water are mixed in a certain proportion to obtain hot water suitable for low-temperature extraction (such as 10 - 80 °C); the low-temperature hot water is injected into the tea brewing bucket, and the ultrasonic extraction unit is started for extraction; the mechanical vibration effect of ultrasonic waves can accelerate the dissolution of the effective components in the tea and improve the extraction efficiency; after extraction is completed, the tea outlet solenoid valve is opened to discharge the tea; the advantage of the ultrasonic extraction brewing mode is that low-temperature extraction helps to retain the aroma and nutritional components in the tea and is suitable for teas that are sensitive to temperature or require low-temperature extraction. (3) The circulating brewing mode combines the advantages of hot water brewing and circulating flow; the hot water outlet valve is opened to inject hot water into the tea brewing bucket, and then the circulating solenoid valve and the water pump are opened simultaneously to make the water in the tea brewing bucket form a circulating flow; the circulating flow helps the tea to be fully wetted and the tea soup to be evenly mixed, improving the brewing effect; after brewing is completed, the tea outlet solenoid valve is opened to discharge the tea; the advantage of the circulating brewing mode is that through the circulating flow, it can ensure the full contact between the tea and the water, improve the concentration and taste of the tea soup, and is suitable for teas that require long-term brewing or need to fully extract the tea components. In summary, through three different working modes and their combined modes, the refined control and optimization of the tea brewing process are realized to meet the brewing requirements of different teas.

[0028] Compared with the prior art, the utility model has the following beneficial effects:

[0029] (1) A hot water device is added to directly provide hot water for the tea brewing bucket, simplifying the operation process; compared with the heating structure integrated in the tea brewing bucket, the hot water provided by the hot water device can have a variety of temperature range options, and the tea brewing time can be significantly shortened, thus improving the overall tea brewing efficiency; effectively shortening the morning opening preparation time of the store or the waiting time for tea brewing during daily operation, approximately reducing by 30% to 40%;

[0030] (2) An ultrasonic extraction brewing unit and a circulating brewing mode are added, which together with the original hot water brewing mode constitute three flexible brewing methods, meeting the brewing requirements of different teas and making the tea brewing process more diversified and refined;

[0031] (3) A special tea outlet device, including a tea container, is equipped, making the discharge of the tea soup fast and hygienic, further improving the user experience and efficiency. Description of the Drawings

Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0036] Embodiment 1

[0037] As Figure 1 and Figure 2 shown, this embodiment provides a new type of integrated extraction and intelligent tea brewing machine, including the following devices:

[0038] The hot water device 1 is located at the back of the tea brewing machine and includes a total inlet valve 11 and a heating device 12. One end of the total inlet valve 11 is connected to the water inlet, and the other end of the total inlet valve 11 is connected to the heating device 12 for providing hot water to the tea brewing device 2.

[0039] The tea brewing device 2 is located at the top of the tea brewing machine and includes a tea brewing bucket 22, an ultrasonic extraction and brewing unit 23, and a water pump 25. The water inlet end of the tea brewing bucket 22 is connected to the heating device 12 through a hot water outlet valve 21. An ultrasonic extraction and brewing unit 23 is provided at the bottom of the tea brewing bucket 22. The water outlet end of the tea brewing bucket 22 is connected to the water pump 25 through a circulation solenoid valve 24. The water pump 25 sends the circulating water to the tea brewing bucket 22. The tea brewing device 2 has three working modes:

[0040] In the hot water brewing mode, after hot water brewing in the tea brewing bucket 22 through the hot water outlet valve 2l, the tea discharging solenoid valve 31 is opened.

[0041] In the ultrasonic extraction and brewing mode, low-temperature hot water is obtained through a mixing valve. After low-temperature extraction by the ultrasonic extraction and brewing unit 23 in the tea brewing bucket 22, the tea discharging solenoid valve 31 is opened.

[0042] The cyclic brewing mode, through the hot water outlet valve 21, the circulation solenoid valve 24 and the water pump 25, after the tea brewing barrel 22 conducts hot water circulation brewing, the tea outlet solenoid valve 31 is opened;

[0043] The tea outlet device 3, located at the lower part of the tea brewing machine, includes a tea outlet solenoid valve 31 and a tea holding barrel 32. One end of the tea outlet solenoid valve 31 is connected to the water pump 25, and the other end of the tea solenoid valve is connected to the tea holding barrel 32.

[0044] As Figure 1 and Figure 2 shown, through adding an ultrasonic extraction and brewing unit 23, a hot water device 1, adding a cyclic brewing mode and equipping a dedicated tea outlet device 3, this technical solution realizes the comprehensive optimization of the tea brewing process. Specifically, through the independently set hot water device 1, the flexibility of water temperature control is enhanced, and the water temperature range can be adjusted according to needs. Whether it is high-temperature brewing to stimulate the aroma of tea leaves or low-temperature extraction to retain nutrients, it can be easily handled. Through the ability of precise temperature control, the tea brewing time can be significantly shortened, improving the overall tea brewing efficiency. It is suitable for commercial occasions such as milk tea shops and tea houses that need to quickly respond to customer needs, and can effectively shorten the morning opening preparation time of the store or the tea brewing waiting time during daily operation by about 30% to 40%, significantly improving the operation efficiency. On the basis of traditional hot water brewing, adding a cyclic brewing mode and an ultrasonic extraction and brewing mode makes the tea brewing process more diversified and refined; in cyclic brewing, through the cooperation of the water pump 25 and the circulation solenoid valve 24, the water in the tea brewing barrel 22 forms a circulating flow, which is used for the full infiltration of tea leaves and the uniform mixing of tea soup, and the number of cycles and time can also be adjusted according to the tea leaf characteristics and brewing requirements to achieve precise control of the tea soup taste; the flexible switching of the three brewing modes meets the brewing requirements of different tea leaves. Equipping a dedicated tea outlet device 3, including a tea holding barrel 32, is a direct manifestation of the tea brewing machine's emphasis on user experience and hygiene and safety. It not only ensures the quick discharge of tea soup, but also effectively avoids the pollution problem of tea soup during the discharge process through the independent tea holding barrel 32, ensuring the purity and hygiene of the tea soup.

[0045] In addition, according to the above-mentioned new extraction and brewing integrated intelligent tea brewing machine of the present invention, it may also have the following additional technical features:

[0046] According to an embodiment of the present invention, the tea brewing machine further includes:

[0047] A control device, located at the back of the tea brewing machine, includes a controller, and the controller is respectively connected to the hot water device 1, the tea brewing device 2, the tea outlet device 3, the alarm device and the display device;

[0048] An alarm device, located at the top of the tea brewing machine, includes an alarm indicator light and a buzzer, and is used to remind the user of abnormal tea brewing;

[0049] The display device is located at the upper part of the tea-making machine and includes a touch screen for displaying and inputting tea-making information.

[0050] In this technical solution, the tea-making information is set through the touch screen. The controller receives the signal and starts the hot water device 1 to heat to the set temperature. After the water heating is completed, the controller controls the hot water to flow into the tea-making device 2. During the tea-making process, if an abnormality occurs (such as too high water temperature), the alarm device (indicator light and buzzer) will be immediately activated to remind the user. After the tea-making is completed, the controller starts the tea discharging device 3, and the tea soup flows into the tea container. During the whole process, the touch screen displays the tea-making status in real time, and the user can view or adjust the settings at any time.

[0051] According to an embodiment of the present invention, the heating device 12 further includes a quick heater. One end of the heating water tank is connected to the main inlet valve 11, and the other end of the heating water tank is connected to the quick heater. The quick heater is connected to the water inlet end of the tea-making bucket 22 through the hot water outlet valve 21. The heating water tank is used to heat the high-temperature water temperature to the set temperature, and the quick heater is used to heat the water temperature to the temperature required for tea-making.

[0052] In this technical solution, when the main inlet valve 11 is opened, the normal temperature water enters the heating water tank through the pipeline. The heating element (such as an electric heating tube) in the heating water tank starts to work, heating the high-temperature water temperature to the set temperature. The set temperature is preset to reduce the heating burden of the subsequent quick heater and improve the overall energy efficiency. In the initial heating stage, in the heating water tank, the water is continuously heated to the set temperature. Once this temperature is reached, the heating water tank will stop heating or reduce the heating power to keep the water temperature stable. The heated water flows through the pipeline to the quick heater. In the final heating stage, the quick heater receives the high-temperature water from the heating water tank and immediately starts heating. The heating element heater in the quick heater quickly raises the water temperature to the temperature required for tea-making. The temperature range is set according to the brewing requirements of different teas to ensure that the tea can fully release its aroma. In the water outlet stage: when the water temperature reaches the temperature required for tea-making, the quick heater sends the heated water into the water inlet end of the tea-making bucket 22 through the hot water outlet valve 21.

[0053] According to an embodiment of the present invention, the heating device 12 further includes a mixing valve, one end of which is connected to the main inlet valve 11, and the other end is connected to the hot water tank, and the low-temperature water is obtained by exchanging the ratio of high-temperature water and normal temperature water.

[0054] In this technical solution, the required temperature of hot water is obtained by mixing high-temperature water and normal temperature water. Compared with directly heating the normal temperature water to the target temperature, the water outlet flow is more stable. By adjusting the flow ratio of high-temperature water and normal temperature water, the water temperature after mixing can be accurately controlled. The low-temperature water is mainly used for extraction. Extraction can be achieved with water at different temperatures: cold extraction is 10 - 20 °C, warm extraction is 30 - 60 °C, and hot extraction is about 80 °C.

[0055] According to an embodiment of the present utility model, the tea brewing bucket 22 is provided with a one-way interface that cooperates with the tea brewing machine. The water inlet end and the water outlet end of the tea brewing bucket 22 are respectively connected to two one-way interfaces. When the tea brewing bucket 22 comes into contact with the tea brewing machine, the one-way interface opens.

[0056] In this technical solution, when the tea brewing bucket 22 comes into contact with the tea brewing machine, the one-way interface will automatically open, allowing water to flow smoothly into and out of the tea brewing bucket 22, avoiding problems such as water leakage and seepage that may exist in traditional tea brewing methods, and improving the efficiency of tea brewing.

[0057] According to an embodiment of the present utility model, the three working modes set by the tea brewing device 2 allow for combined use.

[0058] In this technical solution, (1) The hot water brewing mode is suitable for most teas that require high-temperature brewing. By directly opening the hot water outlet valve 21, hot water that has reached the preset temperature (such as 85 - 95 °C) in the heating device 12 is quickly injected into the tea brewing bucket 22 for traditional hot water brewing. After brewing is completed, the tea outlet solenoid valve 31 is opened to pour the brewed tea soup into the tea container. The advantage of the hot water brewing mode is that it is simple and direct, and can quickly complete the brewing process, and is suitable for teas that require a higher water temperature. (2) The ultrasonic extraction brewing mode uses the ultrasonic extraction unit 23 to extract tea components under low-temperature conditions. High-temperature water and normal-temperature water are mixed in a certain proportion through the mixing valve to obtain hot water suitable for low-temperature extraction (such as 10 - 80 °C). The low-temperature hot water is injected into the tea brewing bucket 22, and the ultrasonic extraction unit 23 is started for extraction. The mechanical vibration effect of ultrasonic waves can accelerate the dissolution of effective components in the tea, improving the extraction efficiency. After extraction is completed, the tea outlet solenoid valve 31 is opened to discharge the tea. The advantage of the ultrasonic extraction brewing mode is that low-temperature extraction helps to retain the aroma and nutrients in the tea, and is suitable for teas that are sensitive to temperature or require low-temperature extraction. (3) The circulating brewing mode combines the advantages of hot water brewing and circulating flow. The hot water outlet valve 21 is opened to inject hot water into the tea brewing bucket 22, and then the circulating solenoid valve 24 and the water pump 25 are opened simultaneously to make the water in the tea brewing bucket 22 form a circulating flow. The circulating flow helps to fully soak the tea and evenly mix the tea soup, improving the brewing effect. After brewing is completed, the tea outlet solenoid valve 31 is opened to discharge the tea. The advantage of the circulating brewing mode is that through the circulating flow, it can ensure full contact between the tea and the water, improving the concentration and taste of the tea soup, and is suitable for teas that require long-term brewing or require full extraction of tea components. In summary, through the three different working modes and their combined modes, the fine control and optimization of the tea brewing process are realized to meet the brewing requirements of different teas.

[0059] The usage process of the above embodiment is as follows:

[0060] Such as Figure 1 and Figure 2As shown, the user sets the tea-making information through the touch screen on the top of the tea-making machine, including the required water temperature, brewing mode, etc. The tea-making information is sent to the control device located on the back of the tea-making machine, and the controller then starts the entire tea-making process;

[0061] The hot water device 1 starts to work, the main inlet valve 11 opens, and the normal temperature water enters the heating water tank through the pipeline; the electric heating tube in the heating water tank heats the high-temperature water to the set temperature. The preliminary heating is used to reduce the burden on the subsequent speed heater and improve energy efficiency; when the water temperature reaches 70 °C, the heating water tank stops heating or reduces the power to maintain the water temperature stability; if a higher temperature is needed as required, the heated water flows into the speed heater, and the heating element in the speed heater quickly raises the water temperature to the range of 85 - 95 °C set by the user to meet the brewing requirements of different teas;

[0062] If the user selects the hot water brewing mode, the hot water outlet valve 21 opens, and the high-temperature hot water is directly injected into the tea brewing bucket 22 for traditional hot water brewing;

[0063] If the user selects the ultrasonic extraction brewing mode, the mixing valve in the heating device 12 will work simultaneously to obtain hot water suitable for low-temperature extraction (10 - 80 °C) by mixing high-temperature water and normal temperature water; utilize the mechanical vibration effect to accelerate the dissolution of the effective components in the tea;

[0064] If the user selects the circulating brewing mode, the hot water outlet valve 21, the circulating solenoid valve 24, and the water pump 25 open simultaneously, and the water in the tea brewing bucket 22 forms a circulating flow to ensure full contact between the tea and the water and uniform mixing of the tea soup;

[0065] During the tea-making process, the control device monitors various parameters in real time, such as water temperature, brewing time, etc., and displays the current tea-making status on the touch screen; if an abnormality occurs (such as too high water temperature), the alarm device (including the alarm indicator light and the buzzer) will be immediately activated to remind the user to pay attention.

[0066] After the tea-making is completed, the controller activates the tea discharging device 3, the tea discharging solenoid valve 31 opens, and the tea soup flows into the tea receiving bucket 32 located at the lower part of the tea-making machine through the pipeline; the user can take out the brewed tea soup from the tea receiving bucket 32 at any time for customers to enjoy;

[0067] After the entire tea-making process is over, the user can view the tea-making records or make settings for the next tea-making through the touch screen; the one-way interface between the tea brewing bucket 22 and the tea-making machine ensures the smooth entry and exit of water into and out of the tea brewing bucket 22, while avoiding problems such as water leakage and seepage, and improving the tea-making efficiency.
