Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent furniture, and particularly relates to an intelligent tea table. Background Art

[0002] Tea is also known as the mysterious oriental leaves. Tea also contains trace elements such as catechins, cholestenone, caffeine, inositol, folic acid, and pantothenic acid, and is a good product suitable for all ages. The ancients emphasized making friends over tea. Therefore, in China, tea is not only an essential item for daily life, but also an auxiliary item indispensable for making friends and entertaining guests. In modern society, the tea table is not only a place for making and drinking tea, but also a place for people to demonstrate their cultivation, and even more a "stage" for social interaction.

[0003] Tea is divided into six categories according to the production process, namely black tea, white tea, green tea, yellow tea, oolong tea, and dark tea. The tea category can be determined by observation and smelling, observing the shape and color of the tea leaves and smelling the aroma of the tea. In life, the process of making tea is usually to put the tea leaves into a teapot, pour an appropriate amount of hot water into the teapot, after brewing for a period of time, pour the tea into a fair cup, and then pour the tea from the fair cup into the tea cups for consumption. In this process, the brewing temperature, brewing method, brewing time, and suitable tea sets for different types of tea are all different. Only those who study the tea ceremony can truly master these skills and brew a tea soup with all the color, aroma, and taste.

[0004] However, there are few people who understand tea. Most people can't even distinguish the types of tea, let alone understand the knowledge and skills of making tea. Moreover, the process of making tea is complicated. Even if they have learned tea culture, if they don't make tea for a long time, they are likely to forget. Therefore, most people usually use one teapot and one method to make tea, resulting in the teapot having a mixed taste, the brewed tea not tasting good, wasting tea leaves, and leaving a bad impression on customers when entertaining guests with tea, making a fool of themselves, losing the etiquette of entertaining guests, and even failing to achieve the purpose of meeting guests. Summary of the Invention

Detailed Description of the Invention

[0022] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0023] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0024] In the description of the present invention, unless otherwise specified and defined, it should be noted that the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the communication inside two elements. It can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] Tea is divided into six categories according to the production process, namely black tea, white tea, green tea, yellow tea, oolong tea and dark tea; the type of tea can be distinguished according to the appearance and smell of the tea, and the origin of the tea can be obtained through the appearance of the tea; the brewing temperature, brewing method, brewing time and suitable tea sets for different teas are all different, and the tea is divided into different grades according to the origin, type and years of tea production. The higher the grade of the tea, the more tea polyphenols it contains, and the more times it can be brewed.

[0026] However, some people are not aware of the tea ceremony and know very little about the types and varieties of tea. They can hardly talk about controlling the brewing temperature, brewing method, brewing time and brewing times during the tea-making process. They cannot brew high-quality tea water, cannot enjoy the tea-tasting process better, and will also damage the trace elements in the tea, wasting natural resources.

[0027] During the tea brewing process, the brewing time is very important. Some teas can only be brewed by quickly pouring water and pouring out the tea, such as some black teas and oolong teas. If the brewing time is too long, it will become bitter and astringent; some teas are suitable for slow brewing or boiling. If the brewing time is short, the tea will be tasteless and odorless, such as some green teas or white teas; if the brewing temperature of the tea is too high or the brewing speed is too fast, the trace elements in the tea will be damaged and the tea fragrance will be dispersed; if the brewing temperature is too low or the brewing speed is too slow, the trace elements in the tea cannot be fully extracted and the tea fragrance cannot be fully stimulated, which will lead to a poor tea-tasting experience, greatly reduce the benefits to the body, and waste the tea; if the tea is brewed too many times, the tea water will be too weak and the quality of the tea water will be low, resulting in a poor impression and evaluation of the tea by users. If the brewing times are too few, good tea will be wasted, and neither can achieve a good tea-tasting process.

[0028] Moreover, China is a state of ceremonies and attaches great importance to the way of entertaining guests. Whether in tea talks or in exchanges with friends, tea is an essential item. When entertaining guests with tea, if the quality of the tea water is not well grasped, it may lead to the dissatisfaction of the guests with the current conversation or visit, and the purpose of the talks cannot be achieved, resulting in losing the big for the sake of the small.

[0029] The present invention provides an intelligent tea table, which includes a control unit and a tea brewing unit; the control unit is electrically connected to the tea brewing unit; the control unit is used to obtain tea information and the number of tea tasters, and the control unit is used to obtain tea set information and brewing suggestions according to the tea information and the number of tea tasters; the control unit is also used to control the tea brewing unit to brew tea and serve tea according to the brewing suggestions.

[0030] Specifically, the tea information includes the tea name, tea category, tea origin, tea age and tea grade; the tea set information includes the tea pot material, tea pot capacity, tea cup information and tea cup capacity; the brewing suggestions include the recommended grams, recommended brewing temperature, recommended brewing times, recommended brewing time, recommended brewing water volume, recommended brewing speed.

[0031] Specifically, the tea set information is obtained according to the tea information and the number of tea tasters. For example, the tea fragrance of dark tea is strong, and using a tea set made of purple sand material for brewing is more mellow. Green tea has a sweet smell and a bright tea color. Using a glass tea set for brewing has better visibility and the smell spreads faster. The recommended brewing temperature, recommended brewing time and recommended brewing speed are obtained according to the tea information. The recommended grams, recommended brewing water volume and recommended brewing times are obtained according to the tea set information and the tea information.

[0032] As shown in the appendix Figure 3 As shown, the intelligent tea table further includes a multimedia unit, and the multimedia unit is electrically connected to the control unit. The multimedia device is used to display the tea information and brewing suggestions; specifically, the multimedia device includes one or more of a display screen, a speaker 10 or an indicator light. The display 14 is used to display the tea information and brewing suggestions. The speaker 10 is used to conduct voice broadcasts on the tea information and brewing suggestions. The indicator light is used to reflect the state of the tea brewing unit through different colors.

[0033] As shown in the appendix Figure 3 As shown, the intelligent tea table further includes an identification unit, and the identification unit is electrically connected to the control unit; the identification unit includes a camera and an odor detector. The camera is used to obtain tea images and tea set images. The control unit is used to obtain the tea name and tea origin according to the tea image, and obtain the tea set information according to the tea set image; the odor detector is used to detect the tea odor, and the control unit is used to obtain the tea grade and tea age according to the tea odor detection value; specifically, the tea grade can be judged by whether there are other miscellaneous odors in the tea odor, and the tea age can be judged by the lightness and thickness of the tea fragrance, and these can all be converted into corresponding digital signals by the odor detector.

[0034] Specifically, a text recognition model is stored in the control unit. First, the text on the tea package is extracted through the text recognition model to read the existing tea information. For the tea information not indicated on the tea package, it is obtained through the following method:

[0035] Create or obtain a convolutional neural network model. Select the tea images, tea odor detection values, corresponding tea information, and brewing suggestions of 500 types of tea to train the convolutional neural network model until it converges. Then select 500 different tea images for testing. When the accuracy of the output tea information and brewing suggestions reaches the target value, the test is completed. Store the tested convolutional neural network model in the control unit. Obtain the tea image to be stored through the camera and transmit it to the control unit. The control unit inputs the tea image into the convolutional neural network model, and the convolutional neural network model outputs the unread tea information.

[0036] As shown in the Figure 1 attachment, for the convenience of tea storage, the intelligent tea table further includes a storage unit, and the storage unit is electrically connected to the control unit; the storage unit includes a plurality of storage boxes 3; the control unit is also used to number the storage boxes 3, and during the storage process of tea and tea sets, associate the tea information and tea set information with their corresponding storage box 3 numbers respectively.

[0037] In one embodiment, the multimedia unit further includes an input device, and the input unit is used to obtain the tea name or tea category; for the convenience of taking tea, the storage box 3 further includes a box body, a box door, and a stepping motor connected to the box door. The control unit is also used to control the stepping motor of the corresponding storage box 3 to start according to the obtained tea name or tea category; specifically, the input device includes one or more of a radio or a keyboard.

[0038] In one embodiment, the storage box 3 is divided into a tea storage box and a tea set storage box 3. A second pressure sensor is further provided at the bottom of the tea storage box, and the second pressure sensor is used to monitor the weight of the tea in the tea storage box. The control unit is used to give a low tea quantity reminder when the weight of the tea in the tea storage box is lower than the set value.

[0039] Specifically, the control unit is further configured to, after starting the stepper motor, identify the amount of tea taken through the second pressure sensor, and control the multimedia unit to give a tea-taking prompt according to the recommended brewing weight, where the recommended brewing weight is the net weight of the dry tea leaves. If the amount of tea taken is greater than the recommended brewing weight, the display screen shows the caption "Excessive Tea Taken", or the speaker 10 emits an alarm sound, or the speaker 10 gives a voice broadcast of "Excessive Tea Taken", or the indicator light turns on a red light; if the amount of tea taken is less than the recommended brewing weight, the display screen shows the caption "Please Continue to Take Tea", or the speaker 10 emits an alarm sound, or the speaker 10 gives a voice broadcast of "Please Continue to Take Tea", or the indicator light turns on a yellow light; among them, the caption, letter size, caption color, and caption style of the display 14, or the voice broadcast text, sound color, and volume of the speaker 10, or the indicator light color can all be adjusted according to the user's preferences and habits.

[0040] As shown in the Figure 1 attachment, an infrared sensor 2 is also provided at the cabinet door 4. After the control unit detects a change in the value of the second sensor, it activates the infrared sensor 2 to detect obstacles. When no obstacles are detected near the cabinet door 4 within the detection time, the stepper motor for the cabinet door 4 is activated again. The detection time can be set according to the user's habits, such as 10s, 15s, 30s, or 1min, etc. When the user finishes taking tea or tea sets, the cabinet door 4 of the storage box 3 is automatically closed to prevent the tea leaves from getting damp or the tea sets from being contaminated due to the user forgetting to close the cabinet door 4.

[0041] As shown in the Figure 1 attachment, the tea brewing unit includes a heating device 11, a kettle 12, a teapot 13, a fair cup 15, a pumping pipeline 9, a brewing pipeline 8, a separation pipeline 7, and a tea outlet pipeline 17; the kettle 12 is located above the heating device 11. One end of the pumping pipeline 9 is connected to the water inlet of the kettle 12, and one end of the brewing pipeline 8 is connected to the water outlet of the kettle 12. The other end of the brewing pipeline 8 is provided with a first interface for connecting to the water inlet of the teapot 13 to connect the brewing pipeline 8 with the teapot 13. Both ends of the separation pipeline 7 are respectively provided with a second interface and a third interface. The second interface is used to connect to the water outlet of the teapot 13, and the third interface is used to connect to the water inlet of the fair cup 15 to connect the teapot 13 with the fair cup 15; one end of the tea outlet pipeline 17 is provided with a fourth interface for connecting to the water outlet of the fair cup 15 to connect the tea outlet pipeline 17 with the fair cup 15; specifically, the kettle 12, teapot 13, fair cup 15, pumping pipeline 9, brewing pipeline 8, and separation pipeline 7 of the tea brewing unit can be placed under the tabletop 1 of the tea table, or only the pumping pipeline 9, brewing pipeline 8, and separation pipeline 7 can be placed under the tabletop of the tea table, so as to keep the tabletop 1 of the intelligent tea table spacious and tidy and increase the storage space on the tabletop 1.

[0042] Specifically, since the water for making tea and the brewed tea are at a relatively high temperature, the brewing pipe 8, the separation pipe 7, and the tea outlet pipe 17 are all made of heat-resistant and food-grade pipes. In one embodiment, for ease of installation and structural distribution, the water pumping pipe 9, the brewing pipe 8, and the separation pipe 7 can also be made of pipes with high flexibility. For ease of holding tea, a section of the tea outlet pipe 17 located on the tabletop 1 is selected to be a rigid pipe, and the end of the tea outlet pipe 17 without a second threaded interface is located above the tabletop 1 (the tabletop 1 is specifically the tabletop 1 of the intelligent tea table), and the opening of this port faces downward. Specifically, the distance between the water outlet end of the tea outlet pipe 17 and the tabletop 1 should be greater than 5 cm and less than 20 cm. In this embodiment, the tea outlet pipe 17 can be in an L shape or a cane shape, and the short side opening of the L-shaped pipe or the cane-shaped pipe faces the tabletop 1.

[0043] Specifically, a temperature sensor is also provided inside the kettle 12. The water pumping pipe 9, the brewing pipe 8, the separation pipe 7, and the tea outlet pipe 17 are respectively connected to a first water pump, a second water pump, a third water pump, and a fourth water pump. The first water pump is used to pump water through the water pumping pipe 9 into the kettle 12. The second water pump is used to pump the water in the kettle 12 through the brewing pipe 8 into the teapot 13. The third water pump is used to pump the brewed tea in the teapot 13 through the separation pipe 7 into the fair cup 15. The fourth water pump is used to pump the brewed tea in the fair cup 15 out through the separation pipe 7. The control unit is also used to control the start and stop of the first water pump, the second water pump, the third water pump, the fourth water pump, and the heating device 11. As shown in the appendix Figure 4 The tea-making steps specifically include:

[0044] Tea loading and water pumping step: The tea-making device contains tea leaves with the same weight as the recommended grams. The control unit controls the first water pump to start and pumps the corresponding amount of water into the kettle 12 according to the recommended water volume.

[0045] Water boiling step: The control unit controls the heating device 11 to start and stops the heating device 11 according to the detected value of the temperature sensor and the recommended brewing temperature.

[0046] Brewing step: The control unit controls the second water pump to start and pumps the heated water into the tea-making device, and measures the brewing time.

[0047] Separation step: When the brewing time reaches the recommended control time, the control unit controls the third water pump to start according to the start time of the second water pump and the recommended brewing time, and pumps the brewed tea in the tea-making device into the fair cup 15.

[0048] Tea outlet step: The control unit starts the fourth water pump and pumps the brewed tea in the fair cup 15 out through the tea outlet pipe 17 and distributes it into each teacup (16).

[0049] During the brewing step, the control unit also controls the motor speed of the second water pump according to the recommended brewing speed to control the water outlet speed of the second water pump; alternatively, a speed-changing device is provided on the water pump, and the control unit controls the water outlet speed of the second water pump through the speed-changing device.

[0050] In one embodiment, the tea brewing unit further includes a tea holding table 5 and a rotating motor; the tea holding table 5 is located below the port of the tea outlet pipe 17 that does not have the fourth threaded interface, and a plurality of tea holding positions 18 are circumferentially distributed on the tea holding table 5; the rotating motor is connected to one of the tea holding table 5 or the tea outlet pipe 17 to make the tabletop 1 rotate relative to the tea holding table 5 or the tea outlet pipe 17;

[0051] The point where the tea water flows out from the port of the tea outlet pipe 17 that does not have the second threaded interface and falls on the tabletop 1 is called the tea outlet landing point. As shown in the appendix Figure 2 As shown, if the tea outlet pipe 17 rotates relative to the tabletop 1, the tea outlet pipe 17 is installed at the center position of the tea holding table 5, so that each tea outlet landing point falls on the distribution circumference of the tea holding positions 18; as shown in the appendix Figure 1 As shown, if the tea holding table 5 rotates relative to the tabletop 1, the tea holding table 5 is located below the port of the tea outlet pipe 17 that does not have the fourth threaded interface, so that when the tea holding table 5 rotates, each tea holding position 18 can pass through the tea outlet landing point.

[0052] Specifically, during the production process, the number of tea holding positions 18 is determined according to the size of the tea table. The larger the tea table, the more people can sit around it, and the more the number of tea holding positions 18; the distribution circle size of the tea holding positions 18 is determined according to the number of tea holding positions 18; the center position of the distribution circle of the tea holding positions 18 is determined according to the rotation mode of the tea holding table 5 and the tea outlet pipe 17. If the tea holding positions 18 rotate, the center of the distribution circle of the tea holding positions 18 is located on one side of the tea outlet pipe 17. If the water outlet pipe rotates, the center of the distribution circle is the position where the tea outlet pipe 17 is installed on the tabletop 1; the shape of the tea outlet pipe 17 is determined according to the positions of the tea holding positions 18, so that the tea water in the tea outlet pipe 17 can accurately fall onto each tea holding position 18; the size and installation position of the tea holding table 5 are determined according to the distribution circle of the tea holding positions 18.

[0053] Specifically, the control unit is used to control the fourth water pump and the rotating motor to start and stop alternately until the start and stop times of the fourth water pump are equal to the number of tea-tasting people or after the rotating motor rotates 360°, stop the fourth water pump and start the rotating motor; the control unit is also used to control the duration of one water pumping action of the fourth water pump according to the capacity of the tea set; the control unit is also used to determine the rotation angle of the rotating motor for one start according to the angle between the tea holding positions 18.

[0054] The tea serving steps are as follows: The tea cups 16 are respectively located on the tea serving positions 18. The camera captures images of the tea serving table 5 and the tea outlet pipe. The control unit checks the angle between the tea outlet point of the tea outlet pipe and the nearest tea serving position 18 based on the images of the tea serving table 5 and the tea outlet pipe. If the angle is not 0, the control unit controls the rotation motor to rotate by the same angle as the angle; until the angle is 0, the control unit controls the fourth water pump to start and controls the fourth water pump to stop according to the capacity of the tea set. The control unit controls the rotation motor to start, so that the next tea serving position 18 is located at the tea outlet point of the tea outlet pipe. The control unit controls the fourth water pump to start again and controls the fourth water pump to stop again according to the capacity of the tea set. The control unit controls the rotation motor to start again, so that the next tea serving position 18 is located at the tea outlet point of the tea outlet pipe,... until the start and stop times of the fourth water pump are equal to the number of tea-tasting people or the rotation motor rotates 360°, then the fourth water pump and the rotation motor start are stopped.

[0055] In one embodiment, a first pressure sensor is further provided below the tea serving position 18. The first pressure sensor is electrically connected to the control unit and is used to detect whether a tea cup 16 is placed on the tea serving position 18. In the tea serving step, after the control unit controls the rotation motor to start, if there is no tea cup 16 on the tea serving position 18 that coincides with the tea outlet point, the control unit controls the rotation motor to continue rotating until the rotation stops when there is a tea cup 16 placed on the tea serving position 18 that coincides with the tea outlet point, and then controls the fourth water pump to start. When a tea set is not placed on a certain tea serving position 18 on the tea serving table 5 in time, the controller can judge in time and does not discharge water at this tea serving position 18, avoiding wasting tea water or polluting the tea serving table 5.

[0056] As shown in the Figure 3 attachment, the tea brewing unit further includes an operation panel 6. The operation panel 6 is arranged on the tabletop. The operation panel 6 includes a brewing button 20 and a tea serving button 21; the brewing button 20 is used to send a brewing instruction to the control unit, and the tea serving button 21 is used to send a tea serving instruction to the control unit; the control unit is used to repeat the tea brewing steps according to the brewing instruction; the control unit is used to repeat the tea serving steps according to the tea serving instruction.
