[0041] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0042] Example 1

[0043] See Figures 1 to 4 This utility model provides a beverage brewing device, including a body 10, a stirring assembly 20, and a heating element 30. The body 10 has a brewing chamber 11, and a dispensing port 12 is provided at the top of the brewing chamber 11. The stirring assembly 20 includes a stirrer 21 and a driving element 22. The stirrer 21 is disposed in the brewing chamber 11, and the driving element 22 can drive the stirrer 21 to rotate around a first axis 100. The heating element 30 is disposed in the brewing chamber 11 and can dry the brewing chamber 11 and the stirrer 21.

[0044] During the beverage preparation process, the beverage to be prepared enters the brewing chamber 11 through the dispensing port 12 and mixes with water within the chamber. The stirring unit 22 drives the stirrer 21 to rotate around the first axis 100, ensuring the beverage is fully dissolved. Heating by the heating element 30 further enhances the dissolving efficiency. After brewing and cleaning the brewing chamber 11, the heating element 30 dries both the chamber and the stirrer 21, preventing bacterial growth. By placing the heating element 30 within the brewing chamber 11, both the beverage and the chamber / stirrer 21 can be heated, reducing the number of components and lowering the overall cost of the machine.

[0045] For example, the dispensing port 12 is provided with an openable lid. After opening the lid, the beverage to be brewed can be added to the dispensing port 12, and water can also be injected into the brewing chamber 11 through the dispensing port 12. The lid can be opened by the operator, either by pulling it open or by rotating it.

[0046] In this embodiment, a brewing tray 40 is provided at the dispensing port 12. The brewing tray 40 is used to hold the beverage to be brewed and can move between an open position and a closed position. When the brewing tray 40 is in the open position, at least a portion of the brewing tray 40 is outside the machine body 10; when the brewing tray 40 is in the closed position, the brewing tray 40 is inside the machine body 10. When a beverage needs to be brewed, the brewing tray 40 is moved to the open position, so that at least a portion of the brewing tray 40 is outside the machine body 10, making it convenient to add the beverage to be brewed onto the brewing tray 40 from outside the machine body 10. After adding the beverage, the brewing tray 40 is moved to the closed position to start water dispensing.

[0047] In order to pour the beverage to be brewed on the brewing tray 40 into the brewing chamber 11, water is poured from top to bottom. The water flows down from the top of the brewing tray 40 and impacts the brewing tray 40, so that the beverage to be brewed enters the brewing chamber 11.

[0048] The brewing tray 40 includes a flexible part 41 with a slit 411. The slit 411 opens under the impact of water flow, allowing the beverage to be brewed on the brewing tray 40 to enter the brewing chamber 11. When no water is being added, the slit 411 is closed, preventing the beverage from falling off the brewing tray 40. When water is being added, the slit 411 opens under the impact of water flow, allowing the beverage to flow downwards on the brewing tray 40.

[0049] In this embodiment, the beverage brewing device further includes a spray assembly 50, which includes a water supply pipe 51 and a spray head 52 connected to the water supply pipe 51. The spray head 52 is located at the dispensing port 12 and is used to spray water into the brewing chamber 11. Spraying water ensures even water distribution, facilitating the complete dissolution of the beverage. A heating device 53 can be installed on the water supply pipe 51 to enable the spray head 52 to spray warm or hot water at a set temperature.

[0050] The brewing tray 40 moves between the open and closed positions without interfering with the spray head 52, thus its movement path is horizontal. A clearance opening is provided on the side of the machine body 10, allowing the brewing tray 40 to move between the open and closed positions. When the brewing tray 40 is in the open position, at least a portion of it is within the clearance opening, meaning it does not need to be completely detached from the machine body 10, preventing loss. When the brewing tray 40 is in the closed position, it does not protrude from the clearance opening, ensuring a neat appearance.

[0051] For example, the brewing disc 40 is movable between an open position and a closed position via a pluggable mechanism. In the closed position, the brewing disc 40 is limited by friction between itself and the body 10. For example, the body 10 is provided with a button, which, when triggered, can activate the drive assembly, thereby driving the brewing disc 40 to move between the open and closed positions. The drive assembly can be a cylinder or a solenoid valve.

[0052] In this embodiment, as Figure 2 As shown, a rebound mechanism 60 is provided between the brewing tray 40 and the body 10. Pressing the edge of the brewing tray 40 causes it to squeeze the rebound mechanism 60, triggering the mechanism to eject the brewing tray 40. Pushing the brewing tray 40 back inward causes it to squeeze the rebound mechanism 60 back to its original position. An elastic element 70 is provided between the brewing tray 40 and the body 10, applying a pulling force to the brewing tray 40 to keep it in the closed position. The rebound mechanism 60 is an existing structure, also known as a press-type elastic self-locking mechanism, often used for opening and closing cabinet doors and for inserting and removing memory cards. The detailed structure of the rebound mechanism 60 will not be described in detail here.

[0053] A pressing groove 13 is recessed on the outer surface of the body 10 at the position corresponding to the clearance opening. When the brewing tray 40 is in the closed position, part of the edge of the brewing tray 40 protrudes from the clearance opening and is located in the pressing groove 13, making it convenient for the operator to press. The inner wall of the pressing groove 13 can be curved to fit the operator's fingers and achieve smooth pressing.

[0054] The stirring assembly 20 can fully stir the liquid in the brewing chamber 11, and the heating element 30 can heat the liquid in the brewing chamber 11. In order to avoid interference between the stirrer 21 and the heating element 30, the stirrer 21 and the heating element 30 are arranged vertically at intervals in the brewing chamber 11, for example; the heating element 30 is disposed on the inner wall of the brewing chamber 11, and the circumferential edge of the stirrer 21 is spaced apart from the heating element 30.

[0055] In this embodiment, a clearance cavity 2111 extending along the first axis 100 is formed in the middle of the stirrer 21, and the heating element 30 is disposed within the clearance cavity 2111. Since the clearance cavity 2111 extends along the first axis 100, and the stirrer 21 rotates around the first axis 100, the heating element 30, located within the clearance cavity 2111, does not need to rotate with the stirrer 21, facilitating the routing of the heating element 30. Furthermore, by disposing the heating element 30 in the middle of the stirrer 21, it is convenient to dry the stirrer 21.

[0056] The bottom end of the stirrer 21 is located outside the brewing chamber 11 and connected to the drive unit 22, i.e., the drive unit 22 is located at the bottom of the body 10. The clearance chamber 2111 extends outside the body 10, and a sealing ring is provided between the stirrer 21 and the body 10 to prevent water leakage. The top of the clearance chamber 2111 is sealed to prevent liquid from entering the clearance chamber 2111 and damaging the heating element 30.

[0057] For example, the drive unit 22 includes a motor, which can directly drive the stirrer 21 or indirectly drive the stirrer 21 through a gear transmission mechanism.

[0058] The stirrer 21 includes a central shaft 211 and a plurality of stirring blades 212 disposed on the outer peripheral surface of the central shaft 211. The central shaft 211 extends along the first axis 100 and is connected to the drive member 22. A clearance cavity 2111 is disposed inside the central shaft 211 and extends to the outside of the machine body 10. A wire connected to the heating member 30 extends along the clearance cavity 2111 to the outside of the machine body 10 and is connected to a circuit board outside the machine body 10.

[0059] For example, multiple stirring blades 212 are arranged at intervals along the circumferential and axial directions of the central axis 211. In this embodiment, the stirring blades 212 extend a predetermined length along the axial direction of the central axis 211, and multiple stirring blades 212 are arranged at intervals around the circumferential direction of the central axis 211. The space between adjacent stirring blades 212 serves as a stirring chamber, and the beverage to be brewed and water flow downward into the stirring chamber together.

[0060] The stirring blade 212 can extend along a plane, a curved surface, or a combination of both. For example, the stirring blade 212 includes a first stirring section 2121 and a second stirring section 2122. One end of the first stirring section 2121 is connected to the central shaft 211, and the other end is connected to the second stirring section 2122. The first stirring section 2121 and the second stirring section 2122 extend in different directions. By providing the first stirring section 2121 and the second stirring section 2122 with different extending directions, comprehensive stirring can be achieved in all directions, resulting in more thorough stirring.

[0061] Exemplarily, the first stirring part 2121 extends radially along the central axis 211; and / or, the second stirring part 2122 extends arcuately around the axis of the central axis 211. In one embodiment, the first stirring part 2121 extends radially along the central axis 211, and the second stirring part 2122 extends arcuately around the axis of the central axis 211. During stirring, the central axis 211 rotates, causing the first stirring part 2121 and the second stirring part 2122 to rotate synchronously, thereby causing water to flow circumferentially along the central axis 211.

[0062] The bottom of the brewing chamber 11 is provided with a water outlet 14 and a wastewater outlet 15. A first switch valve 16 is provided at the water outlet 14, and a second switch valve 17 is provided at the wastewater outlet 15.

[0063] When using it, the process consists of three steps: brewing, washing, and drying.

[0064] During the brewing process, pressing the edge of the brewing tray 40 triggers the rebound device 60, causing the brewing tray 40 to pop out from the clearance opening. The brewing tray 40 can be pulled outwards a certain distance as needed, and the beverage to be brewed, such as milk powder, can be placed on it. Pushing the brewing tray 40 back inwards returns it to the closed position. The beverage to be brewed can be one type or multiple types, and the operator can mix them as needed.

[0065] The spray assembly 50 is activated, and the spray head 52 sprays water onto the brewing tray 40. The temperature of the water sprayed from the spray head 52 can be set according to actual needs. The gap 411 on the flexible part 41 opens under the impact of the water flow, allowing the beverage to be brewed on the brewing tray 40 to enter the brewing chamber 11, specifically the stirring chamber of the stirrer 21. After a first set water spraying time (e.g., 10 seconds), the water spraying stops, the stirring assembly 20 is activated, and the stirrer 21 stirs. The heating element 30 can be turned on or off as needed. Turning on the heating element 30 accelerates the dissolution of the beverage. After a second set stirring time (e.g., 30 seconds), stirring stops, the first switch valve 16 is opened, and the brewed beverage flows out from the water outlet 14. Then, the first switch valve 16 is closed.

[0066] During the cleaning process, the spray assembly 50 is activated, and the spray head 52 sprays water onto the brewing tray 40. The gaps 411 on the flexible part 41 open under the impact of the water flow, allowing water to enter the brewing chamber 11, specifically the stirring chamber of the agitator 21. After a third set water spraying time (e.g., 15 seconds), the water spraying stops, the agitator 20 is activated, and the agitator 21 stirs. The heating element 30 can be turned on or off as needed. Turning on the heating element 30 accelerates the cleaning of the brewing chamber 11. After a fourth set stirring time (e.g., 30 seconds), stirring stops, the second switch valve 17 is opened, and the wastewater generated during cleaning flows out from the wastewater outlet 15. Then, the second switch valve 17 is closed.

[0067] The cleaning process can be performed multiple times as needed. After cleaning, the drying process is performed. During the drying process, the heating element 30 is turned on to dry the stirrer 21 and the brewing chamber 11. After the heating element 30 has been turned on for a fifth set time (e.g., 20 seconds), the drying process is stopped.

[0068] The beverage brewing device described above can be embedded in a wall cabinet, taking up little space, and can automatically fill, dispense, and clean itself, reducing the labor intensity of the operator.

[0069] Example 2

For simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The difference is that an elastic element 70 is provided between the brewing tray 40 and the body 10, and the body 10 is provided with a button 81 and a latch 82. By pressing the button 81, the latch 82 can be disengaged from the brewing tray 40, thereby causing the brewing tray 40 to pop out from the clearance opening under the action of the elastic element 70. After adding the beverage to be brewed into the brewing tray 40, pushing the brewing tray 40 inward causes it to engage with the latch 82 and be fixed in the closed position.

[0071] Button 81 and latch 82 are engaged by a bevel, allowing latch 82 to disengage from the slot on the brewing tray 40 when button 81 is pressed. Latch 82 includes a latch body and a first spring. One end of the latch body can be inserted into the slot on the brewing tray 40, and the other end is connected to the machine body 10 by the first spring. Button 81 includes a button body and a second spring. One end of the button body engages with the bevel of latch 82, and the other end protrudes from the machine body 10 for easy pressing. The second spring is positioned between the button body and the machine body 10.

[0072] The beverage brewing device in any of the above embodiments can be used independently, or as part of a tea bar machine, or as part of a water purifier. The tea bar machine has a countertop located below the water outlet 14 of the beverage brewing device, facilitating the placement of cups and other utensils to catch brewed beverages. The water purifier has a brewing function and includes a water inlet system and a filter cartridge. The filter cartridge is located in the water inlet system to filter the incoming water.
