Description

Technical Field

[0001] The utility model relates to a capsule coffee machine, in particular to a head device of a capsule coffee machine. Background Art

[0002] As a popular beverage, coffee has a large consumer group worldwide. With the accelerating pace of life, convenient and fast coffee-making methods are increasingly favored by people. Due to its simple operation, fast production, high taste consistency and other characteristics, capsule coffee machines have gradually become common coffee-making equipment in families and offices.

[0003] Existing capsule coffee machines generally include a base and a head device for placing coffee capsules. Users only need to put the coffee capsule into the head device, close the coffee machine, and select the corresponding button or knob, and the coffee machine will automatically complete the coffee extraction process and output a cup of fragrant coffee.

[0004] However, the structural design of the head device in the prior art is not reasonable enough. When cooperating with the capsule, the sealing performance is poor, which easily leads to leakage of coffee during the dissolution process, affecting the taste and quality of coffee, and may also cause waste of coffee liquid. Summary of the Utility Model

[0005] In view of the above-mentioned defects of the prior art, the utility model provides a head device of a capsule coffee machine, which includes a pressing plate, a pressing cover, a capsule cup and a capsule cup seat; the pressing plate is arranged on the pressing cover, and a pressing needle protrusion is arranged on the bottom surface of the pressing plate; the pressing cover includes an upper pressing cover and a lower pressing cover; an upper needle tube is arranged on the lower pressing cover; the upper end of the upper needle tube is connected to a water delivery pipe joint, and the lower end needle head protrudes outside the lower pressing cover; the pressing cover can be buckled on the capsule cup seat, and at this time, the pressing needle protrusion of the pressing plate is directly above the upper end of the upper needle tube; a cup seat opening is arranged on the bottom surface of the capsule cup seat; the capsule cup is installed on the cup seat opening; and a lower needle tube is arranged at the bottom of the capsule cup.

[0006] Further, a flange is arranged at the cup mouth part of the capsule cup, and the capsule cup is installed on the cup seat opening on the bottom surface of the capsule cup seat through the flange at the cup mouth.

[0007] Further, the pressing plate is installed on the pressing cover through a hinge shaft and a torsion spring, and the pressing plate can be reset by the torsion spring after being pressed down.

[0008] Further, the water delivery pipe joint is connected to an external water delivery hose.

[0009] In the head of the utility model, the coffee capsule is fixed by the pressing cover and the capsule cup seat, the coffee capsule is punctured by the upper and lower needle tubes, and then water is injected into the coffee capsule through the upper needle tube, and the formed coffee solution is output from the lower needle tube. Its sealing performance is good, and it is not easy for coffee to leak during the dissolution process.

[0010] The following will further explain the concept, specific structure and technical effects of the present utility model in conjunction with the attached drawings, so as to fully understand the purpose, features and effects of the present utility model. Description of the Drawings

[0011] Figure 1 is a perspective view of the head device of a capsule coffee machine in a preferred embodiment of the present utility model;

[0012] Figure 2 is Figure 1 exploded view of;

[0013] Figure 3 is Figure 1 a perspective view of the capsule cup in. Detailed Embodiment

[0014] The following introduces multiple preferred embodiments of the present utility model with reference to the accompanying drawings of the specification, making its technical content clearer and easier to understand. The present utility model can be embodied in many different forms of embodiments, and the protection scope of the present utility model is not limited to the embodiments mentioned in the text.

[0015] As Figures 1-3 shown, in a specific embodiment of the head device of a capsule coffee machine according to the present utility model, the head device includes a pressing plate 1, a pressing cover 2, a capsule cup 3 and a capsule cup holder 4. The pressing plate 1 is installed on the pressing cover 2 through a hinge shaft 11 and a torsion spring 13. A pressing needle protrusion 13 is provided on the bottom surface of the pressing plate 1. The pressing cover 2 includes an upper pressing cover 21 and a lower pressing cover 22. An upper needle tube 23 is provided on the lower pressing cover 22. The upper end of the upper needle tube 23 is connected to a water delivery pipe joint 24, and the lower end needle protrudes outside the lower pressing cover 22. The pressing cover 2 can be buckled on the capsule cup holder 4. A cup holder opening 31 is provided on the bottom surface of the capsule cup holder 4. A flange 42 is provided at the cup mouth part of the capsule cup 4, and a lower needle tube 41 is provided on the bottom plate of the capsule cup 4. The capsule cup 4 is installed on the cup holder opening 31 on the bottom surface of the capsule cup holder 4 through the flange 42 at the cup mouth.

[0016] When the head device is working, first place the coffee capsule 5 in the cup holder opening 31, then close the pressing cover 2, and at the same time press down the pressing plate 1. At this time, the pressing needle protrusion 13 at the bottom of the pressing plate 1 presses down the upper needle tube 23 in the pressing cover 2, piercing the upper part of the coffee capsule 5. At the same time, the lower needle tube 41 at the bottom of the capsule cup 4 pierces the lower part of the coffee capsule 5. Water from an external hose (not shown) passes through the water delivery pipe joint 24, enters the coffee capsule 5 through the upper needle tube 23, and the coffee solution then flows out through the lower needle tube 41 at the bottom of the coffee capsule 5. The pressing plate 1 is reset by the torsion spring 13.

[0017] The present utility model uses upper and lower needle tubes to pierce the coffee capsule, then injects water into the coffee capsule through the upper needle tube, and the formed coffee solution is output from the lower needle tube, with good sealing performance and not easy to leak during the coffee dissolution process.

[0018] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art should fall within the protection scope determined by the claims.
