Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a water outlet structure for a coffee machine water tank. Background Technology

[0002] As people's living standards improve, coffee machines are becoming increasingly common in homes and offices. As a crucial component for storing water, the design of the water dispensing mechanism in a coffee machine has a vital impact on its overall performance and user experience.

[0003] Currently, most coffee machine water tanks on the market have limitations in their water outlet design. Some water tanks use a simple on / off spout design, which is rather crude in its opening and closing process, making it difficult to precisely control the water flow rate and speed. During coffee brewing, different types of coffee require different water flow rates. This imprecise water outlet design cannot meet the diverse needs of coffee brewing, thus affecting the consistency of the coffee's taste and quality. Utility Model Content

[0004] To address the problems mentioned above, this utility model provides a water outlet structure for a coffee machine water tank, which effectively solves the problem that the existing coffee machine water tanks use simple on / off water outlets, making it difficult to accurately control the water volume and speed, thus affecting the taste and quality stability of the coffee.

[0005] This utility model adopts the following technical solution: a water outlet structure for a coffee machine water tank, including a coffee machine water tank, a circular water outlet at the bottom of the coffee machine water tank, a silicone circular sealing valve adapted to the circular water outlet, bearing mounting holes on both sides of the circular water outlet on the bottom side wall of the coffee machine water tank, bearings installed in the bearing mounting holes, a rotating shaft rotatably connected between the two bearings, the rotating shaft passing through and fixedly connected to the silicone circular sealing valve, a first gear connected to one end of the rotating shaft, a drive motor mounted on the bottom of the coffee machine water tank through a mounting plate, a second gear connected to one end of the drive motor, the second gear meshing with the first gear, and a groove for the second gear to mesh with the first gear at the bottom of the coffee machine water tank.

[0006] Furthermore, four raised pads are installed at the bottom of the coffee machine's water tank.

[0007] Furthermore, a waterproof sealing ring is provided inside the bearing mounting hole, and the waterproof sealing ring is nested between the outer ring of the rotating shaft and the bearing mounting hole.

[0008] Furthermore, the drive motor is a stepper motor with forward and reverse rotation functions, and the control terminal of the stepper motor is connected to a controller.

[0009] Furthermore, the edge of the silicone circular sealing valve is provided with an annular sealing protrusion, which fits tightly against the inner wall of the circular water outlet.

[0010] The advantages of this invention are as follows: A drive motor rotates the second gear, which meshes with the first gear, thereby driving the rotating shaft to rotate, and further driving the silicone circular sealing valve to rotate. This gear transmission method allows for precise control of the rotation angle and speed of the silicone circular sealing valve, thus accurately controlling the water output and speed from the water tank. This meets the water flow requirements in different coffee-making processes, ensuring the stability of coffee quality. A matching silicone circular sealing valve is installed inside the circular water outlet. Due to the excellent flexibility and elasticity of silicone, it can achieve a tight fit with the circular water outlet, effectively preventing water leakage from the water tank. This greatly improves the sealing performance of the water tank, ensuring its sealing in non-draining states, making the coffee machine safer and more stable to use. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0018] See Figure 1-4 As shown, a water outlet structure for a coffee machine includes a coffee machine water tank 1. A circular water outlet 2 is provided at the bottom of the coffee machine water tank 1. A silicone circular sealing valve 3 adapted to the circular water outlet 2 is provided inside the circular water outlet 2. Bearing mounting holes 4 are provided on both sides of the circular water outlet 2 on the bottom side wall of the coffee machine water tank 1. Bearings 5 ​​are installed in the bearing mounting holes 4. A rotating shaft 6 is rotatably connected between the two bearings 5. The rotating shaft 6 passes through the silicone circular sealing valve 3 and is fixedly connected to it. A first gear 7 is connected to one end of the rotating shaft 6. A drive motor 8 is installed at the bottom of the coffee machine water tank 1 through a mounting plate. A second gear 9 is connected to one end of the drive motor 8. The second gear 9 is meshed with the first gear 7. A groove 10 for the second gear 9 to mesh with the first gear 7 is provided at the bottom of the coffee machine water tank 1 at the location of the first gear 7.

[0019] The bottom of the coffee machine water tank 1 is equipped with four raised pads 11, which can provide stable support for the water tank, making the water tank more stable, and at the same time prevent the movement of the silicone circular sealing valve 3 from being obstructed.

[0020] A waterproof sealing ring 41 is installed inside the bearing mounting hole 4, and the waterproof sealing ring 41 is nested between the outer ring of the rotating shaft 6 and the bearing mounting hole 4. This effectively prevents water in the water tank from leaking out of the bearing mounting hole 4. This prevents water from entering the bearing 5 and related transmission components, preventing the bearing 5 from rusting or being damaged due to water intrusion, ensuring the normal rotation of the rotating shaft 6 and the bearing 5, and improving the reliability and service life of the entire water outlet structure.

[0021] The drive motor 8 is a stepper motor with forward and reverse rotation capabilities. The stepper motor's control terminal is connected to a controller, allowing for precise control of its rotation angle and speed. The controller enables flexible adjustment of the opening degree of the silicone circular sealing valve as needed, thus achieving precise control over the water flow rate and speed. Users can adjust the water flow to suit different coffee-making needs, resulting in coffee with a better taste. Simultaneously, the forward and reverse rotation function facilitates the opening and closing of the sealing valve, making control more convenient.

[0022] The silicone circular sealing valve 3 has an annular sealing protrusion 31 on its edge. The annular sealing protrusion 31 fits tightly against the inner wall of the circular water outlet 2. The annular sealing protrusion 32 increases the sealing area and sealing pressure between the silicone circular sealing valve 3 and the circular water outlet 2, further improving the sealing performance. It can better prevent water leakage in the water tank and ensure a good sealing effect even when the water pressure in the water tank is high, thus improving the safety and reliability of the coffee machine.

[0023] Working Principle: In the initial state or when water discharge from the tank is not required, the silicone circular sealing valve 3 is tightly embedded in the circular outlet 2. The annular sealing protrusion 31 on the edge of the silicone circular sealing valve 3 fits tightly against the inner wall of the circular outlet 2, forming a good sealing effect and preventing water from the tank from flowing out of the circular outlet 2. When water discharge from the tank is required, the operator sends a command to the controller through the relevant equipment. After receiving the command, the controller controls the drive motor 8 to start and rotate clockwise. The output end of the drive motor 8 is connected to the second gear 9. As the drive motor 8 rotates, the second gear 9 also rotates. Since the second gear 9 meshes with the first gear 7, and the first gear 7 is connected to one end of the rotating shaft 6, the second gear 9 drives the first gear 7 to rotate, which in turn drives the rotating shaft 6 to rotate. The rotating shaft 6 passes through the silicone circular sealing valve 3 and is fixedly connected to it. When the rotating shaft 6 rotates, it drives the silicone circular sealing valve 3 to rotate together. The silicone circular sealing valve 3 rotates around the rotating shaft 6, gradually opening the circular outlet 2. At this point, water in the tank can flow out through the circular outlet 2 to supply water to the coffee machine. Once the required water level is reached, the operator or the water level control system within the coffee machine sends another command to the controller. The controller then controls the drive motor 8 to rotate counterclockwise, which in turn drives the second gear 9 to rotate in reverse. The second gear 9 then drives the first gear 7 and the rotating shaft 6 to rotate in the opposite direction, causing the silicone circular sealing valve 3 to rotate back and embed itself into the circular outlet 2. The annular sealing protrusion 31 then re-fits tightly against the inner wall of the circular outlet 2, sealing the outlet and stopping the water flow from the tank.
