Description

Technical Field

[0001] This utility model relates to the field of liquid preparation equipment technology, and in particular to a double-layer water tank and beverage preparation device. Background Technology

[0002] Currently, the widely used mineralization technologies mainly fall into two categories. One involves embedding mineral components into activated carbon rods, which are then sintered after being uniformly mixed with carbon powder. However, this method faces technical bottlenecks such as a short duration of mineralization efficiency, the potential for safety hazards with excessive ore addition leading to a longer lifespan, and unstable release of mineral components. The other method is the mineralization-water mixing mode, which precisely controls the mixing ratio of mineralized water and pure water to achieve the desired mineralized water output. While this mode avoids the disadvantages of sintered carbon rods, it still suffers from uneven mixing of mineralized water, making it difficult to guarantee a stable final mineralized water output.

The control block is configured such that when the water level in the first water tank is lower than a first predetermined minimum water level, the buoyancy force on the control block is less than the sum of the control block's own weight and the magnetic force of the magnet, causing the control block to be attracted by the magnet and thus blocking the mineralized water outlet. Furthermore, the control block is configured such that when the water level in the first water tank is higher than a first predetermined maximum water level, the buoyancy force on the control block is greater than the sum of the control block's own weight and the magnetic force of the magnet, causing the control block to detach from the magnet and thus opening the mineralized water outlet.

[0020] The beverage preparation apparatus provided in this application includes any of the double-layer water tanks described above.

[0021] In some embodiments of this application, the beverage preparation device is a coffee machine or a milk tea machine.

[0022] The double-layer water tank provided in this application has different functions for its upper and lower layers. The upper layer mixes mineralized water, while the lower layer stores mineralized water, thus flexibly solving the problem of water outlet stability. The upper water tank cleverly utilizes the balance between buoyancy, magnetism, and gravity to control the closure of the outlet, greatly reducing costs.

[0023] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0028] The specific embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and examples, so as to better understand the solution of this utility model and its advantages in various aspects. However, the specific embodiments and examples described below are for illustrative purposes only and are not intended to limit this utility model.

[0029] Figure 1 A double-layer water tank according to an embodiment of this application is shown. The double-layer water tank includes a first water phase 10 and a second water tank 20.

[0030] like Figure 1As shown, the first water tank 10 is located above, and the second water tank 20 is located below. The first water tank 10 is used to mix mineralized concentrate and pure water. The ratio of mineralized concentrate to pure water can be determined according to needs, and then water can be mixed according to the ratio to obtain mineralized water with a predetermined concentration. The mineralized concentrate described in this application contains mineral ions beneficial to the human body, such as potassium, calcium, sodium, magnesium, strontium, and zinc, and its concentration is measured in TDS, which is between 0 and 250 mg / L. Figure 1 As shown, the first water tank 10 is provided with a mineralized concentrate inlet 11, a pure water inlet 12, and a mineralized water outlet 13. In this application, the mineralized water outlet 13 is provided with a magnet 14. In this embodiment, the magnet 14 is a magnetite.

[0031] The second water tank 20 is used to store the mineralized water obtained by mixing the mineralized concentrate and pure water in the first water tank 10. For example... Figure 1 As shown, the second water tank 20 is provided with an inlet 21 and an outlet 22, wherein the inlet 21 is connected to the mineralized water outlet 13.

[0032] The double-layer water tank of this application is also provided with a control block, which is located at the mineralized water outlet 13. The control block includes a plastic body 31, a magnetic material, and a limiting member 32. In this embodiment, the magnetic material is located inside the plastic body 31. In other embodiments of this application, the magnetic material is connected to the plastic body 31 and can be located on either side of the plastic body 31. In this embodiment, the magnetic material is an iron block.

[0033] The limiting member 32 restricts the longitudinal (i.e., vertical) movement distance of the plastic body 31 within the first water tank 10. In this embodiment, the limiting member 32 is a spring, with one end connected to the plastic body 31 and the other end connected to the magnet 14. In other embodiments of this application, the limiting member can also be a rope, and the material is not limited, as long as it can limit the longitudinal movement distance of the plastic body 31 within the first water tank 10. In other embodiments of this application, the limiting member can also be a tube, and the material and shape are not limited. The plastic body 31 is located inside the tube, and the tube has holes or slits, which can limit the longitudinal movement distance of the plastic body 31 within the first water tank 10.

[0034] In this application, the control block is configured such that when the water level in the first water tank is lower than a first predetermined minimum water level, the buoyancy force on the control block is less than the sum of the control block's own weight and the magnetic force of the magnet, causing the control block to be attracted by the magnet and thus blocking the mineralized water outlet. Furthermore, the control block is also configured such that when the water level in the first water tank is higher than a first predetermined maximum water level, the buoyancy force on the control block is greater than the sum of the control block's own weight and the magnetic force of the magnet, causing the control block to detach from the magnet and thus opening the mineralized water outlet.

[0035] For example, the first predetermined minimum water level is h1, the first predetermined maximum water level is h2, and the buoyancy force on the control block is F. 浮The weight of the control block is G, and the magnetic force exerted on the control block by magnet 14 is F. 磁 When the water level in the first water tank 10 is lower than the first predetermined minimum water level h1, the buoyancy force F on the control block... 浮 The force F is less than the sum of the control block's own weight G and the magnetic force exerted by the magnet. 磁 That is, F 浮 <G+F 磁 At this time, magnet 14 can hold the control block in place, and the control block will block the mineralized water outlet 13, so the mineralized water in the first water tank 10 cannot flow into the second water tank 20.

[0036] When the water level in the first water tank 10 is higher than the first predetermined maximum water level h2, the buoyancy force F on the control block is... 浮 The force is greater than the weight G of the control block itself and the magnetic force F exerted by the magnet. 磁 The sum of, i.e., F 浮＞ G+F magnet. At this time, the magnet 14 can no longer hold the control block, and the control block separates from the magnet 14, thereby opening the mineralized water outlet 13, and the mineralized water in the first water tank 10 flows into the second water tank 20.

[0037] The double-layer water tank provided in this application has different functions for its upper and lower layers. The upper layer mixes mineralized water, while the lower layer stores mineralized water, thus flexibly solving the problem of water outlet stability. The upper water tank cleverly utilizes the balance between buoyancy, magnetism, and gravity to control the closure of the outlet, greatly reducing costs.

[0038] Figure 1 In the illustrated embodiment, the double-layered water tank further includes a control module (not shown) and a float 40, wherein the float 40 is located within the second water tank 20. The control module is configured to open the inlet 21 when the position of the float 40 within the second water tank 20 is below a second predetermined minimum water level, and is also configured to close the inlet 21 when the position of the float 40 within the second water tank 20 is above a second predetermined maximum water level. The control module controls the opening and closing of the inlet 21 based on the water level in the second water tank 20 via the float 40.

[0039] In other embodiments of this application, another float located within the first water tank 10 may be included. In this case, the control module may be configured to open the controlled mineralization concentrate inlet 11 and the pure water inlet 12 when the position of the float within the first water tank 10 is lower than a first predetermined minimum water level, and the control module may also be configured to close the controlled mineralization concentrate inlet 11 and the pure water inlet 12 when the position of the float within the first water tank 10 is higher than a first predetermined maximum water level. The control module controls the opening and closing of the controlled mineralization concentrate inlet 11 and the pure water inlet 12 based on the water level in the first water tank 10 via the float.

[0040] Figure 1In the illustrated embodiment, the double-layered water tank further includes a sterilization device 50, which is an ultraviolet germicidal lamp disposed on the top wall of the first water tank 10. In other embodiments of this application, the ultraviolet germicidal lamp may also be disposed on the top wall of the second water tank 20. In other embodiments of this application, the sterilization device may also be other types, as long as it is capable of sterilizing the water in the first water tank 10 and / or the second water tank 20, and may be disposed within the first water tank 10 and / or the second water tank 20.

[0041] This application further provides a beverage preparation device, including the aforementioned double-layered water tank. This beverage preparation device can be, for example, a coffee machine or a milk tea machine. Because the beverage preparation device provided by this application includes the double-layered water tank, it ensures stability during the water usage process. For example, a coffee machine requires a constant concentration of mineralized water during continuous coffee production; otherwise, inconsistent concentrations will severely affect the taste, flavor, and other user experience aspects of the coffee. Furthermore, when precise control of the ion concentration in the mineralized water is required, the mineralized water concentration can be released sequentially and mixed evenly in the mixing tank to achieve the optimal ratio of mineralized water, thereby ensuring the taste of the prepared coffee or milk tea.

[0042] Obviously, the above embodiments are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of the present invention.
