Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and specifically to a brewing structure and a coffee machine. Background Technology

[0002] Currently, existing coffee machines on the market use a pipe-connected structure, which connects the water pipe to the top cover.

[0003] For example, utility model patent CN201409817Y discloses a detachable water spout structure for a coffee machine, including a water tank and a funnel frame located on the upper part of the machine body. A water spout is located on the upper part of the water tank, and the spout has a telescopic opening and closing mechanism. A water spout connecting pipe is located on the top cover. When the cover is closed, the upper end of the water spout extends into the water spout connecting pipe to form a hot water channel; when the cover is opened, the upper end of the water spout separates from the water spout connecting pipe, and the hot water flows back into the water tank. However, in actual use, this prior art has a safety issue: after the top cover is opened, some hot water splashes out during the hot water backflow process, causing scalding.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the safety issue of hot water spraying out during the hot water recirculation process after the lid is opened in existing technologies, which could cause scalding, this utility model provides a brewing structure and a coffee machine.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A brewing structure includes a funnel frame with a water shut-off valve assembly for connecting to a water supply device; and a top cover hinged to the funnel frame, which has a water outlet assembly and a water inlet assembly. The first end of the water inlet assembly is connected to the water outlet assembly, and the second end of the water inlet assembly is correspondingly positioned with the water shut-off valve assembly. When the top cover is closed relative to the funnel frame, it drives the water inlet assembly to open the water shut-off valve assembly, thus opening the water path. When the top cover is open relative to the funnel frame, it drives the water inlet assembly to separate from the water shut-off valve assembly, thus disconnecting the water path. This design, with the water shut-off valve assembly mounted on the funnel frame, allows for brewing coffee when the top cover is closed and the water path is disconnected when the top cover is open, preventing hot water from splashing out and causing scalding. The structure is simple and easy to operate.

[0008] According to the above scheme, the water shut-off valve assembly includes a valve core rod and a water shut-off valve. The water shut-off valve is installed on the funnel frame and has a limiting ring inside. The limiting ring has a water passage hole formed on it. The valve core rod is slidably connected to the limiting ring and is used to open or close the water passage hole. When the top cover is closed relative to the funnel frame, it drives the water inlet assembly to push the valve core rod to open the water passage hole. When the top cover is open relative to the funnel frame, it drives the water inlet assembly to separate from the valve core rod, thereby closing the water passage hole. This configuration allows for convenient use by controlling the opening of the water passage hole by driving the valve core rod through the water inlet assembly when the top cover is closed.

[0009] According to the above scheme, the first end of the valve core rod is provided with a limiting block, and the second end of the valve core rod passes through the limiting ring and is fixed with a valve core rod sealing ring. The valve core rod sealing ring is correspondingly set with the water passage hole, and a spring is sleeved on the valve core rod between the limiting block and the limiting ring. With this configuration, in the initial state, the water passage hole is closed under the elastic force of the spring. When the top cover closes relative to the funnel frame, it drives the water inlet assembly to push the valve core rod to open the water passage hole. When the top cover opens relative to the funnel frame, it drives the water inlet assembly to separate from the valve core rod. Under the rebound force of the spring, the valve core rod sealing ring on the valve core rod resets and closes the water passage hole again.

[0010] According to the above scheme, a water shut-off valve sealing ring is provided between the water shut-off valve and the funnel frame, and the water shut-off valve sealing ring abuts against the valve core rod; when the top cover is closed relative to the funnel frame, it drives the water inlet assembly to seal against the water shut-off valve sealing ring, and pushes the water shut-off valve sealing ring to drive the valve core rod to open the water passage hole. In this way, when the top cover is closed relative to the funnel frame, it drives the water inlet assembly to seal against the water shut-off valve sealing ring, preventing water from overflowing when the water passage is open.

[0011] According to the above scheme, the water shut-off valve sealing ring includes an outer ring and an inner ring, which are fixedly connected. The outer ring is fixed at the connection between the water shut-off valve and the funnel frame, and the inner ring abuts against the valve core rod. With this configuration, when the top cover is closed relative to the funnel frame, it drives the water inlet assembly to seal against the end face of the water shut-off valve sealing ring. Under the action of force, the water shut-off valve sealing ring deforms, and the inner ring pushes the valve core rod to open the water passage hole.

[0012] According to the above scheme, the water inlet assembly includes a water inlet connector, the water inlet end of the water inlet connector is correspondingly set with the water shut-off valve, and the water outlet end of the water inlet connector is connected to the water outlet assembly through a water pipe.

[0013] According to the above scheme, the water outlet component includes a water outlet connector, the water inlet end of which is connected to a water pipe, and a connector sealing ring is provided between the water outlet connector and the top cover.

[0014] According to the above scheme, a one-way valve is installed on the top cover, with the inlet end of the one-way valve corresponding to the outlet end of the outlet connector. This configuration, by using the one-way valve, prevents water backflow.

[0015] According to the above scheme, the funnel holder is equipped with a container for holding capsules, and a water dispensing needle is installed on the top cover. The water dispensing needle is positioned correspondingly to the container, and a water dispensing needle sealing ring is provided between the water dispensing needle and the top cover. With this configuration, during operation, when the capsule is placed in the container and the top cover is closed, the water dispensing needle extends into the container and punctures the capsule. At the same time, when the top cover is closed, the water passage is opened to brew coffee, and the coffee liquid falls into the funnel of the funnel holder.

[0016] The coffee machine of this utility model includes a body and the above-mentioned brewing structure, with a funnel holder installed on the body and a water supply device provided on the body.

[0017] The beneficial effects of this utility model are:

[0018] This utility model is designed such that a water shut-off valve assembly is installed on the funnel frame; when the top cover is closed relative to the funnel frame, the water shut-off valve assembly is opened to open the water path, which can be used to brew coffee; when the top cover is opened relative to the funnel frame, the water path is cut off, and hot water will no longer flow out, which can prevent hot water from splashing out when the lid is opened and causing scalding. Its structure is simple and easy to operate. Attached Figure Description

[0028] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 7 As shown, the brewing structure of this utility model includes a funnel frame 8, on which a water shut-off valve assembly for connecting to a water supply device is installed; and a top cover 4, which is hinged to the funnel frame 8. The top cover 4 is provided with a water outlet assembly and a water inlet assembly. The first end of the water inlet assembly is connected to the water outlet assembly, and the second end of the water inlet assembly is correspondingly arranged with the water shut-off valve assembly. When the top cover 4 is closed relative to the funnel frame 8, it drives the water inlet assembly to open the water shut-off valve assembly, thereby opening the water path; when the top cover 4 is open relative to the funnel frame 8, it drives the water inlet assembly to separate from the water shut-off valve assembly, thereby disconnecting the water path. This configuration, with the water shut-off valve assembly installed on the funnel frame 8, allows for brewing coffee when the top cover 4 is closed relative to the funnel frame 8 and disconnects the water path when the top cover 4 is open, preventing hot water from splashing out and causing scalding. The structure is simple and easy to operate.

[0030] In practical applications, the water shut-off valve assembly is in a closed state in its initial non-working state, that is, the state when the top cover 4 is open relative to the funnel frame 8.

[0031] Furthermore, the water shut-off valve assembly includes a valve core rod 12 and a water shut-off valve 13. The water shut-off valve 13 is mounted on the funnel frame 8, and a limiting ring 131 is provided inside the water shut-off valve 13. A water passage hole 132 is formed on the limiting ring 131. The valve core rod 12 is slidably connected to the limiting ring 131, and the valve core rod 12 is used to open or close the water passage hole 132. When the top cover 4 is closed relative to the funnel frame 8, it drives the water inlet assembly to push the valve core rod 12 to open the water passage hole 132. When the top cover 4 is open relative to the funnel frame 8, it drives the water inlet assembly to separate from the valve core rod 12, so that the water passage hole 132 is closed. With this configuration, the opening of the water passage hole 132 can be controlled by the water inlet assembly pushing the valve core rod 12 when the top cover 4 is closed, which is convenient to use.

[0032] Furthermore, the first end of the valve core rod 12 is provided with a limiting block 121, and the second end of the valve core rod 12 passes through the limiting ring 131 and is fixed with a valve core rod sealing ring 14. The valve core rod sealing ring 14 is correspondingly arranged with the water passage hole 132. A spring 11 is sleeved on the valve core rod 12 between the limiting block 121 and the limiting ring 131. With this arrangement, in the initial state, the water passage hole 132 is closed under the elastic force of the spring 11. When the top cover 4 is closed relative to the funnel frame 8, it drives the water inlet assembly to push the valve core rod 12 to open the water passage hole 132. When the top cover 4 is opened relative to the funnel frame 8, it drives the water inlet assembly to separate from the valve core rod 12. Under the rebound force of the spring 11, the valve core rod sealing ring 14 on the valve core rod 12 is reset and the water passage hole 132 is closed again.

[0033] Furthermore, a water shut-off valve sealing ring 10 is provided between the water shut-off valve 13 and the funnel frame 8, and the water shut-off valve sealing ring 10 abuts against the valve core rod 12. When the top cover 4 is closed relative to the funnel frame 8, it drives the water inlet assembly to seal against the water shut-off valve sealing ring 10, and pushes the water shut-off valve sealing ring 10 to drive the valve core rod 12 to open the water passage hole 132. In this way, when the top cover 4 is closed relative to the funnel frame 8, it drives the water inlet assembly to seal against the water shut-off valve sealing ring 10, preventing water from overflowing when the water passage is open.

[0034] In practical applications, when the top cover 4 is closed relative to the funnel frame 8, the water inlet assembly always maintains a sealed contact with the water shut-off valve sealing ring 10.

[0035] Furthermore, the water shut-off valve sealing ring 10 includes an outer ring 101 and an inner ring 102, which are fixedly connected. The outer ring 101 is fixed at the connection between the water shut-off valve 13 and the funnel frame 8, and the inner ring 102 abuts against the valve core rod 12. With this configuration, when the top cover 4 is closed relative to the funnel frame 8, it causes the water inlet assembly to seal against the end face of the water shut-off valve sealing ring 10. Under the action of force, the water shut-off valve sealing ring 10 deforms, and the inner ring 102 pushes the valve core rod 12 to open the water passage hole 132.

[0036] In practical applications, the outer ring 101 and the inner ring 102 are integral structures. The outer ring 101 is formed with a flange, and the water shut-off valve 13 is provided with a groove that matches the flange. The inner ring 102 abuts against the limiting block 121 at the first end of the valve core rod 12.

[0037] Furthermore, the water inlet assembly includes a water inlet connector 41, the water inlet end of which is correspondingly provided with the water shut-off valve 13, and the water outlet end of the water inlet connector 41 is connected to the water outlet assembly through a water pipe 9.

[0038] Preferably, the water pipe 9 is a silicone pipe or a plastic pipe.

[0039] Furthermore, the water outlet assembly includes a water outlet connector 1, the water inlet end of which is connected to the water pipe 9, and a connector sealing ring 3 is provided between the water outlet connector 1 and the top cover 4.

[0040] Furthermore, a one-way valve 2 is installed on the top cover 4, with the inlet end of the one-way valve 2 corresponding to the outlet end of the outlet connector 1. This configuration prevents water backflow by using the one-way valve 2.

[0041] Furthermore, the funnel holder 8 is equipped with a container 81 for holding the capsule 7, and a water outlet needle 5 is installed on the top cover 4. The water outlet needle 5 is correspondingly arranged with the container 81, and a water outlet needle sealing ring 6 is provided between the water outlet needle 5 and the top cover 4. With this arrangement, during operation, when the capsule 7 is placed in the container 81 and the top cover 4 is closed, the water outlet needle 5 is driven into the container 81 to puncture the capsule 7. At the same time, when the top cover 4 is closed, the water passage is opened to brew coffee, and the coffee liquid falls into the funnel of the funnel holder 8.

[0042] In practical applications, the water outlet end of the water outlet needle 5 is set to correspond to the opening of the container 81, and the water inlet end of the water outlet needle 5 is set to correspond to the one-way valve 2.

[0043] Preferably, the one-way valve 2 is a silicone duckbill valve; when water passes through the circular opening of the silicone duckbill valve, the silicone duckbill valve will open easily, and when water wants to pass through the flat opening of the silicone duckbill valve, the silicone duckbill valve will close (the flat opening of the silicone duckbill valve is closed in its natural state), thus achieving the function of controlling the one-way flow of water; at the same time, it can prevent coffee powder from being sucked back into the water outlet needle 5, avoiding the problem of coffee powder clogging the water outlet needle 5.

[0044] The coffee machine of this utility model includes a body and the above-mentioned brewing structure, with a funnel holder 8 installed on the body and a water supply device provided on the body.

[0045] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims, and all of these forms are within the scope of protection of the present utility model.
