Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and more particularly to a coffee powder hopper for extracting coffee liquid and a coffee machine thereof. Background Technology

[0002] With the popularization of coffee culture, the extraction component of coffee machines, as a core part of coffee making, has attracted much attention for its sealing performance and ease of use. In existing technologies, such as the "Sealed Extraction Component for Coffee Powder" disclosed in Chinese Utility Model Patent Publication No. CN215838420U, the sealed extraction of coffee powder is achieved through the cooperation of a top cover, a cup body, and a silicone stopper. The silicone stopper is positioned on the water outlet at the lower end of the cup body, and its elasticity and water outlet slit structure improve the sealing effect and liquid flow control to a certain extent. However, this existing technology still has the following shortcomings in practical applications:

[0003] (1) The silicone plug is easily lost: The silicone plug in the prior art is an independent small part, which is only installed at the water outlet by interference fit, without any additional connection or positioning structure. Due to its small size and weak correlation with other parts of the extraction component, the silicone plug is easy to separate from the main body of the component during daily disassembly, cleaning or maintenance, which leads to loss and affects the normal use of the extraction component.

[0004] (2) Inconvenient installation of silicone stopper: In the prior art, the silicone stopper is directly installed at the water outlet at the bottom of the cup body, while the filter screen inside the cup body cavity is set on the blocking ring, above the silicone stopper. This structural layout makes the silicone stopper installed below the filter screen, requiring the filter screen to be removed first during installation. Moreover, the installation process is cumbersome due to the limitations imposed by the filter screen and the internal space of the cup body, which affects the convenience of user operation.

[0005] Therefore, in view of the problems of easy loss and inconvenient installation of silicone stoppers in the existing technology, there is an urgent need for an improved coffee powder container structure to optimize the integrity of the components and the ease of installation.

[0032] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described in detail with reference to the embodiments.

[0033] Example 1

[0034] The coffee powder container for extracting coffee liquid includes a container body 10, which holds coffee powder. An end cap is fitted to the port of the container body 10, and the end cap is sealed to the container body 10 via a sealing ring. The end cap has several water inlet holes. A filter screen is installed at the bottom of the inner cavity of the container body 10, through which the coffee liquid flows out after being filtered. An elastic plug 11 and an elastic washer 12 are installed at the bottom of the outer surface of the container body 10. Both the elastic plug 11 and the elastic washer 12 are made of silicone. The elastic plug 11 is installed at the liquid outlet 101 at the bottom of the container body 10. When the liquid pressure at the liquid outlet 101 reaches a set value, the end face of the elastic plug 11 deforms, and the coffee liquid is forced out through the gap between the elastic plug 11 and the liquid outlet 101, thus achieving coffee extraction. An elastic washer 12 surrounds the elastic plug 11, and a silicone connecting part 13 is fixedly connected between the elastic washer 12 and the elastic plug 11. The elastic plug 11 is fixedly connected to the elastic washer 12 through the connecting part 13, and the two form an integral component. On the one hand, during installation, there is no need to position and operate the elastic plug 11 separately. The installation of the elastic plug 11 at the liquid outlet 101 can be completed synchronously through the cooperation of the elastic washer 12 and the chamber body 10, which simplifies the installation steps and improves the ease of installation. On the other hand, the connection between the elastic plug 11 and the elastic washer 12 through the connecting part 13 avoids the problem that the elastic plug 11 is easy to fall off and lose due to its small size and weak connection with other components, thus enhancing the integrity and reliability of the component.

[0035] Multiple connecting portions 13 are evenly distributed around the elastic plug 11. In this embodiment, there are four connecting portions 13. The elastic washer 12, the elastic plug 11, and the connecting portions 13 are integrally formed into a single unit. The integral molding design further enhances the integrity and structural stability of the component, avoiding the risk of separation of parts during assembly. The multiple evenly distributed connecting portions 13 make the connection between the elastic plug 11 and the elastic washer 12 more balanced and firm, ensuring a more stable installation position of the elastic plug 11 at the liquid outlet.

[0036] The two adjacent connecting parts 13, elastic washer 12 and elastic plug 11 together form a liquid passage hole 14, which is used to allow coffee liquid to pass through. The liquid passage hole 14 formed by the connecting parts 13, elastic washer 12 and elastic plug 11 not only ensures that the coffee liquid flows out smoothly, but also further strengthens the stability of the overall structure by relying on the connection of the connecting parts 13 to the elastic plug 11 and elastic washer 12.

[0037] The bottom of the tank body 10 is provided with a gasket groove 102 and a liquid outlet groove 103. The annular baffle 104 on the inner side of the gasket groove 102 is provided with a notch 105. In this embodiment, there are four notches 105, which are evenly distributed on the annular baffle 104. The notches 105 correspond one-to-one with the connecting parts 13. The gasket groove 102 is connected to the liquid outlet groove 103 through the notches 105. The elastic gasket 12 is installed on the gasket groove 102. The elastic plug 11 and the connecting parts 13 are both installed on the liquid outlet groove 103. The connecting parts 13 connect the elastic gasket 12 and the elastic plug 11 through the notches 105. The assembly method achieved through the gasket groove 102, the liquid outlet groove 103, and the notch 105 makes the installation of the elastic plug 11, the elastic gasket 12, and the connecting part 13 more stable, preventing the components from shifting. At the same time, the components form an orderly spatial layout based on the groove and the notch 105, which not only ensures the reliable connection of the connecting part 13 to the elastic plug 11 and the elastic gasket 12, but also ensures the smooth flow of coffee liquid through the liquid passage hole 14. The overall structure has stronger compatibility, reduces the problem of sealing failure or component loss due to improper installation, and improves the stability of use.

[0038] One end of the outlet hole 101 is connected to the inner cavity of the container 10, and the other end is connected to the outlet tank 103. The coffee liquid in the container 10 flows out through the outlet hole 101 and into the outlet tank 103. The elastic plug 11 is provided with a plug body 111 that is adapted to the outlet hole 101. When the water pressure in the container 10 reaches the set value, an outlet channel 200 is formed between the inner wall of the outlet hole 101 and the plug body 111. When the water pressure in the container 10 does not reach the set value, the outlet channel 200 will not be formed. The plug body 111, the elastic plug 11, the connecting part 13, and the elastic washer 12 form an integral structure. Combined with the adapted layout of the outlet hole 101 and the outlet tank 103, it not only ensures that the outlet channel 200 opens smoothly under the set water pressure, but also improves the installation stability through the cooperation between the components. This reduces the installation deviation or loss problems that are prone to occur when the silicone plug is independent in the prior art, and enhances the reliability of the coffee powder container.

[0039] The outlet hole 101 is conical, and the stopper body 111 is also conical in shape. The elastic stopper 11 has a conical groove 112 corresponding to the stopper body 111. The conical outlet hole 101 and the stopper body 111 form a suitable conical surface fit, which enhances the sealing effect through the tight fit of the conical surfaces when not in operation, effectively preventing coffee leakage. Simultaneously, the conical surface fit makes it easier for the stopper body 111 to be pushed open to form the outlet channel 200 when the water pressure inside the chamber 10 reaches a set value, resulting in a more sensitive pressure response. After dispensing, it can automatically return to its original position, ensuring reliable sealing. The conical groove 112 on the elastic stopper 11 enhances the elastic deformation capability of the stopper body 111, making it easier to deform under pressure to open the outlet channel. The overall structural design further optimizes the sealing performance and the convenience of dispensing control.

[0040] The elastic stopper 11 includes a positioning part 113, and a stopper body 111 is integrally formed on top of the positioning part 113. A positioning element 106 is provided on the bottom surface of the liquid outlet 103, which positions the positioning part 113 at the bottom of the chamber 10. The cooperation between the positioning part 113 and the positioning element 106 provides precise and secure positioning for the elastic stopper 11, avoiding positional deviations during installation. The integrally formed stopper body 111 and the positioning part 113 enhance the structural strength of the elastic stopper 11 itself. Combined with the limiting effect of the positioning element 106, it can effectively prevent the elastic stopper 11 from shifting when the coffee liquid flows or the pressure changes, ensuring that the stopper body 111 and the liquid outlet 101 always maintain a precise fit. This not only ensures the stability of the sealing effect but also reduces the risk of failure due to loose parts, improving the overall structural reliability.

[0041] The positioning element 106 is a column, and there are multiple columns. In this embodiment, there are four positioning elements 106. The positioning part 113 is provided with positioning grooves 114 around its perimeter. The positioning elements 106 are adapted to the positioning grooves 114 and position the positioning part 113 at the bottom of the chamber body 10. The cooperation between the multiple column-shaped positioning elements 106 and the positioning grooves 114 provides multi-directional limiting for the elastic plug 11, preventing the elastic plug 11 from rotating or shifting during installation or use, ensuring that the plug body 111 and the liquid outlet 101 always maintain precise alignment, and enhancing the reliability of the seal. The four columns are evenly distributed and work with the positioning grooves 114 to form a balanced positioning force, making the installation of the elastic plug 11 more stable and reducing the risk of seal failure caused by component shaking. At the same time, this structured positioning method also simplifies the installation operation and improves assembly efficiency.

[0042] A sealing ring 15 is integrally formed on the outer end face of the elastic gasket 12. The integrally formed structure can ensure a more stable positional relationship between the sealing ring 15 and the elastic gasket 12. When the elastic gasket 12 is installed in the gasket groove 102, the sealing ring 15 can fit tightly with the relevant structure at the bottom of the chamber 10, enhancing the overall sealing performance and preventing coffee liquid from leaking from the gap between the elastic gasket 12 and the chamber 10, thereby improving the sealing reliability of the coffee powder chamber.

[0044] Example 2 is basically the same as Example 1, except that there are two connecting parts 13, and the two connecting parts 13 are on the same straight line. In other examples, the number of connecting parts 13 may be three.
