Description

Technical Field

[0001] This application relates to the field of extraction equipment technology, and in particular to a fully automated extraction device. Background Technology

[0002] Tea brewers are used to extract aroma and flavor from tea leaves, while coffee machines and cold brew machines are used to extract aroma and flavor from coffee beans or tea leaves. Therefore, tea brewers, coffee machines, and cold brew machines are all extraction devices. Currently, tea brewers involve directly placing tea leaves into hot water to steep, with the user controlling the steeping time. This manual control is time-consuming, laborious, and results in inconsistent tea flavor. Coffee machines, on the other hand, involve placing ground coffee into a filter container, then spraying heated water onto the coffee grounds. The filtered coffee solution is then collected in a water container. Because the timing of the coffee solution dripping into the water container is unpredictable, the taste of the brewed coffee can vary. Summary of the Invention

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0030] like Figures 1 to 5 As shown in the figure, this application embodiment provides a fully automatic extraction device, including a water container 1, a container lid 2, a tea basket 3, and a transmission mechanism 4. The water container 1 is used to hold liquid, and a heating element 5 is provided at the bottom of the water container 1 to heat the liquid in the water container 1. The container lid 2 is movably connected to the water container 1, and the top of the water container 1 has a container opening. The container lid 2 matches the container opening and has a stop groove 201. The tea basket 3 is movably disposed in the water container 1, and the top of the tea basket 3 has a stop protrusion 202 that matches the stop groove 201. The transmission mechanism 4 is disposed on the water container 1 and movably connected to the tea basket 3. The transmission mechanism 4 drives the tea basket 3 to move along the height direction of the water container 1 inside the water container 1.

[0031] In use, the fully automatic extraction device first adds water to the water container 1, then places tea leaves or coffee powder into the tea basket 3. Next, the heating element 5 is activated to heat the water to the desired temperature (or the heating element may not be activated). Then, the transmission mechanism 4 drives the tea basket 3 to move up and down within the water container 1. When the tea basket 3 moves downwards, it is submerged in the water; when it moves upwards, it is above the water surface. After the coffee or tea is brewed, the transmission mechanism 4 moves the tea basket 3 upwards, causing the stop protrusion 202 on the tea basket 3 to be placed in the stop groove 201, or stopping the tea basket 3 at a predetermined position above the liquid surface. This embodiment, with its tea basket 3 and transmission mechanism 4, can automatically extract tea leaves or coffee without manual control, saving time and effort and ensuring the stability of the taste of the tea or coffee solution. Since the stop protrusion 202 on the tea basket 3 matches the stop groove 201 on the container lid 2, the tea basket 3 can be positioned. When the container lid 2 is removed, the tea basket 3 can be removed together. When the container lid 2 is removed and inverted, the tea basket 3 can be placed and stored conveniently.

[0032] The heating element 5 can be an existing heating plate, heating tube, heating film, or quartz tube, etc., as long as it can heat the liquid in the water container 1. The method of fixing the heating element 5 to the water container 1 is also existing technology. The specific method of fixing the heating element 5 to the water container 1 can refer to the fixing method of the heating element 5 on existing tea brewing devices. The container lid 2 can be connected to the water container 1 by threads, and the container lid 2 can also be placed directly in the container opening. The tea basket 3 is provided with a through hole, through which water can enter and exit the tea basket 3.

[0033] In one embodiment, to detect the temperature of the liquid inside the water container 1, a temperature sensor 6 is installed at the bottom of the water container 1. The temperature sensor 6 is used to detect the temperature of the solution in the water container 1. After the heating assembly 5 starts heating, heating stops when the temperature sensor 6 detects that the solution in the water container 1 has been heated to a predetermined temperature.

[0034] In one embodiment, the water container 1 includes a container body 101 and a container base 102. The container base 102 is located at the bottom of the container body 101 and is connected to the container body 101. The tea basket 3 is movably disposed inside the container body 101, and the heating component 5 is disposed on the container base 102.

[0035] In another embodiment, the water container 1 further includes a handle 103, which is connected to the container body 101 and the container base 102, forming an accommodating cavity 104 between the handle 103, the container body 101, and the container base 102. The handle 103 can be fixed to both the container body 101 and the container base 102 by bolts, and the container body 101 and the container base 102 can also be fixed by bolts. Alternatively, the container body 101 and the container base 102 can be fixed by welding, thus achieving a fixed connection between the container body 101 and the container base 102.

[0036] To enable the tea basket 3 to move within the container body 101, the transmission mechanism 4 includes a motor 401, a conveyor belt 402, a first transmission wheel 403, and a second transmission wheel 404. The motor 401 is mounted on the container base 102. The first transmission wheel 403 is rotatably connected to the container base 102 via a rotating shaft. The second transmission wheel 404 is rotatably connected to the container body 101 via a rotating shaft. The conveyor belt 402 is connected to both the first and second transmission wheels 403. The first transmission wheel 403 is connected to the output shaft of the motor 401, and the motor 401 drives the first transmission wheel 403 to rotate. The conveyor belt 402, the first transmission wheel 403, and the second transmission wheel 404 are all housed within the accommodating cavity 104. When the motor 401 starts, it drives the first transmission wheel 403 to rotate. The first transmission wheel 403 then drives the second transmission wheel 404 to rotate via the conveyor belt 402. The tea basket 3 is movably connected to the conveyor belt 402, allowing the conveyor belt 402 to move the tea basket 3 during transmission. The second drive wheel 404 can also be replaced with a cylinder, and the conveyor belt 402 is connected to the first drive wheel 403 and the cylinder.

[0037] In one embodiment, the container body 101 may further include an inner liner and an outer shell, with a cavity formed between the inner liner and the outer shell, and the conveyor belt 402, the first drive wheel 403 and the second drive wheel 404 may also be disposed in the cavity.

[0038] In one embodiment, to achieve the movable connection between the tea basket 3 and the conveyor belt 402, a first magnetic element 405 is provided on the conveyor belt 402, and a second magnetic element 301 is provided on the tea basket 3. The first magnetic element 405 and the second magnetic element 301 are magnetically attracted to each other. In another embodiment, the first magnetic element 405 is provided on the conveyor belt 402, and the tea basket 3 is made of a magnetically conductive material, which is attracted to the first magnetic element 405. Preferably, the tea basket 3 can be made of magnetically conductive martensitic stainless steel, such as SUS430 stainless steel; the tea basket 3 can also be made of other magnetically conductive materials by electroplating or spraying. After the first magnetic element 405 and the second magnetic element 301 are attracted, or after the first magnetic element 405 and the tea basket 3 are attracted, the conveyor belt 402 can drive the tea basket 3 to move up and down along the inner wall of the container body 101. Since the tea basket 3 is made of a magnetically conductive material, the magnetically conductive material of the tea basket 3 can also be directly attracted to the third magnetic element 203 on the container lid 2.

[0039] To secure the first magnetic component 405 to the conveyor belt 402, a fixing bracket 406 is fixed to the conveyor belt 402. The first magnetic component 405 can be directly fixed to the fixing bracket 406 using screws or clips. It is important to note that the fixing bracket 406 should not interfere with the rotation of the first drive wheel 403 and the second drive wheel 404.

[0040] In one embodiment, the tea basket 3 includes an upper cover 302 and a lower cover 303, which are movably connected. A stop protrusion 202 is located at the top of the upper cover 302 or the bottom of the lower cover 303, or both the top of the upper cover 302 and the bottom of the lower cover 303 are provided with stop protrusions 202. The upper cover 302 and the lower cover 303 can be connected by threads. A third magnetic element 203 is provided on the container lid 2, and a fourth magnetic element 304 is provided on the upper cover 302 or the lower cover 303, or both the upper cover 302 and the lower cover 303. The third magnetic element 203 and the fourth magnetic element 304 are magnetically attracted to each other. Preferably, the fourth magnetic element 304 can be located on the stop protrusion 202. After the stop protrusion 202 of the tea basket 3 is located in the stop groove 201, the third magnetic element 203 and the fourth magnetic element 304 are attracted to each other. There are two second magnetic elements 301, which are located on opposite sides of the upper cover 302 or the lower cover 303. With the above arrangement of the tea basket 3, it is not necessary to distinguish between the upper and lower parts of the tea basket 3 when placing it inside the container body 101.

[0041] In one embodiment, the tea basket 3 further includes an inner frame located inside the upper cover 302 and the lower cover 303. There are two second magnetic elements 301, which may be located on two opposite sides of the inner frame. In one embodiment, the upper cover 302, the lower cover 303, and the inner frame may be made of injection-molded parts or metal parts, etc.

[0042] The number of second magnetic elements 301 is not limited to two; it can also be multiple. The number of second magnetic elements 301 can be set according to the diameter of the tea basket 3. For ease of attraction, when the size of the tea basket 3 is small, the number of second magnetic elements 301 can be three or four; when the size of the tea basket 3 is large, the number of second magnetic elements 301 on it can be six or more. In other embodiments, the second magnetic element 301 can also be a ring magnet, and the number of ring magnets is not specifically limited.

[0043] To secure the third magnetic component 203 to the container lid 2, it can be directly installed inside the lid 2, ensuring it does not come into contact with the liquid. To secure the fourth magnetic component 304 to the upper and lower covers 302 and 303, magnetic baffles 7 are provided on both covers, sealing the fourth magnetic component 304 within them. To secure the second magnetic component 301 to the upper or lower cover 302 or inner frame, magnetic baffles 7 are also provided on these covers, sealing the second magnetic component 301 within them. The magnetic baffles 7 can be welded to the upper or lower cover 302 or inner frame, or sealed with a silicone sealing ring, preventing contact between the second and fourth magnetic components 301 and the liquid.

[0044] It should be noted that the first magnetic component 405, the second magnetic component 301, the third magnetic component 203 and the fourth magnetic component 304 of this application are all magnets. These magnets are M-class (100℃) or higher heat-resistant magnets, and the magnetism of the magnets will not be affected when the temperature of the solution reaches 100℃.

[0045] To detect the movement of the tea basket 3 within the container body 101, a first position sensor 8, a second position sensor 9, and a third position sensor 10 are installed within the container body 101. These sensors are arranged sequentially along the height of the container body 101, with the first position sensor 8 positioned above the second position sensor 9, and the second position sensor 9 positioned between the first and third position sensors 10. Each of these sensors can be fixed to the inner wall of the container body 101. The first position sensor 8, second position sensor 9, and third position sensor 10 are Hall effect sensors or microswitches.

[0046] like Figures 2 to 4As shown, in use, the fully automatic extraction device of this application first adds an appropriate amount of water to the container body 101, and then places the tea basket 3 containing tea leaves or coffee powder at point A or B. When the tea basket 3 is placed at point A, it is connected to the container lid 2 via the third magnetic component 203 and the fourth magnetic component 304. When the tea basket 3 is placed at point B, it is connected to the conveyor belt 402 via the first magnetic component 405 and the second magnetic component 301, or the tea basket 3 attracts the first magnetic component 405 through its own magnetic conductivity. The user selects a function of the product (or tea type, or concentration, etc.), and the fully automatic extraction device starts working, with the heating component 5 starting to heat the water. When the temperature sensor 6 detects that the liquid temperature has reached the set temperature, heating stops, and the transmission mechanism 4 starts working. The conveyor belt 402 drives the tea basket 3 to reciprocate between points B and C, allowing the tea leaves or coffee powder inside to fully blend with the liquid. After completion, the tea basket 3 returns to its initial position at point A or B.

[0047] If the tea basket 3 returns to point A, the first magnetic component 405 on the conveyor belt 402 continues to move clockwise after reaching point A. Upon reaching point A, the stop protrusion 202 on the tea basket 3 engages in the stop groove 201 of the container lid 2, and the conveyor belt 402 continues to move clockwise. Since the stop protrusion 202 of the tea basket 3 is already engaged in the stop groove 201 of the container lid 2 and cannot continue to move, when the first magnetic component 405 on the conveyor belt 402 moves to a position away from the second magnetic component 301 on the tea basket 3, the fourth magnetic component 304 on the tea basket 3 naturally attracts to the third magnetic component 203 on the container lid 2. If the tea basket 3 returns to point B, the conveyor belt 402 stops moving after the first magnetic component 405 on the conveyor belt 402 reaches point B.

[0048] When using the cold brew function of the fully automatic extraction device, add an appropriate amount of water to the container body 101 and place the tea basket 3 containing tea leaves or coffee powder at point A or B. When the tea basket 3 is placed at point A, it is connected to the container lid 2 via the third magnetic component 203 and the fourth magnetic component 304. When the tea basket 3 is placed at point B, it is connected to the conveyor belt 402 via the first magnetic component 405 and the second magnetic component 301, or the tea basket 3 attracts the first magnetic component 405 through its own magnetic conductivity. The user selects a function of the product (or tea type, or concentration, etc.), and the fully automatic extraction device starts working. The conveyor belt 402 drives the tea basket 3 to reciprocate between points B and C, allowing the tea leaves or coffee powder inside to fully blend with the liquid. After completion, the tea basket 3 returns to its initial position at point A or B. If the tea basket 3 returns to point A, the first magnetic component 405 on the conveyor belt 402 continues to move clockwise after reaching point A. Upon reaching point A, the stop protrusion 202 on the tea basket 3 engages in the stop groove 201 of the container lid 2, and the conveyor belt 402 continues to move clockwise. Since the stop protrusion 202 of the tea basket 3 is already engaged in the stop groove 201 of the container lid 2 and cannot continue to move, when the first magnetic component 405 on the conveyor belt 402 moves to a position away from the second magnetic component 301 on the tea basket 3, the fourth magnetic component 304 on the tea basket 3 naturally attracts to the third magnetic component 203 on the container lid 2. If the tea basket 3 returns to point B, the conveyor belt 402 stops moving after the first magnetic component 405 on the conveyor belt 402 reaches point B.

[0049] Since the tea basket 3 is initially positioned at point A, when the operation begins, the first magnetic component 405 on the conveyor belt 402 needs to move the tea basket 3 to point B. Therefore, it is essential to ensure that the attraction force of the conveyor belt 402 on the tea basket 3 is greater than the attraction force of the third magnetic component 203 and the fourth magnetic component 304. After the fully automatic extraction device is powered on, it will by default transport the tea basket 3 to point B; after the operation is completed, the first magnetic component 405 on the conveyor belt 402 will eventually return to point B.

[0050] If the first magnetic component 405 stops at point A after the work is completed, then when the container lid 2 is opened, the tea basket 3 will be attached to the side wall of the container body 101, and the tea basket 3 will not be taken out with it when the container lid 2 is opened. The tea basket 3 and container lid 2 of this application can achieve the following advantages: the container lid 2 can be used as a storage seat for the tea basket 3 when it is upside down, and when there is tea liquid in the tea basket 3, it will prevent it from spilling onto the table and contaminating the table; secondly, when there is high temperature steam inside the container body 101 and the tea basket 3 needs to be removed, the tea basket 3 can be removed together by removing the container lid 2, which can effectively avoid burns and is convenient to take out; the container lid 2, as a storage seat for the tea basket 3, can effectively prevent the tea basket 3 from being contaminated when placed.

[0051] The first position sensor 8 is the initial position sensor. The tea brewing function can only be started when the first position sensor 8 detects that the tea basket 3 is in position; otherwise, only the water boiling function can be started. When the tea basket 3 moves between B and C, the position of the tea basket 3 is detected by the second position sensor 9 and the third position sensor 10. When the tea basket 3 is at position B, it is not in contact with the container lid 2. When the tea basket 3 is at position C, the tea leaves or coffee powder inside is placed in the solution.

[0052] This application, through the installation of the transmission mechanism 4, eliminates the need for manual supervision during tea or coffee extraction, saving time and effort, and improving product stability and consistency of taste. Simultaneously, precise control of water temperature and the brewing frequency of the tea basket 3 ensures a better taste for the extracted beverage. This application also reduces the product's size, making it more convenient to use and store, and broadening its applicability.

[0053] In other embodiments, an automatic water pumping and drainage system can be added to the container base 102 to realize the automatic tea washing function.
