Description

Technical Field

[0001] The utility model relates to the field of coffee machines, in particular to a coffee funnel cake removing device and a coffee machine using the same. Background Art

[0002] A coffee machine is an electrical appliance for coffee making, generally divided into semi-automatic and fully automatic types. Among them, the semi-automatic coffee machine is a traditional Italian coffee machine, which grinds, presses, loads, brews coffee according to manual operation, and manually removes residues; the fully automatic coffee machine is a coffee machine that fully automatically controls the whole process of brewing coffee, including preheating, cleaning, grinding, pressing, brewing, pouring powder, etc., and brews coffee according to scientific data and procedures. With the improvement of living standards, coffee has gradually become a common drink in people's lives. Due to the accelerating pace of life, coffee machines that can quickly brew coffee are favored by people. The above-mentioned coffee machines generally have a funnel with a handle at the extraction port. However, when the above products and similar products extract coffee, after the extraction is completed, the coffee cake in the powder bowl is difficult to fall off from the funnel through pouring operation after being soaked in hot water. Summary of the Utility Model

[0003] To solve the above problems, the present technical solution provides a coffee funnel cake removing device and a coffee machine using the same.

[0004] To achieve the above object, the present technical solution is as follows:

[0005] A coffee funnel cake removing device includes a housing and an extraction chamber that moves relative to the housing. The housing is provided with a water outlet nozzle, and the extraction chamber is provided with a through hole communicating with the water outlet nozzle. The device further includes a filter assembly disposed inside the extraction chamber. The middle part of the filter assembly passes through the extraction chamber and is connected to the housing. A spring is disposed between the middle part of the filter assembly and the housing.

[0006] In some embodiments, the filter assembly includes:

[0007] A filter screen;

[0008] A filter screen support. The filter screen support is provided with a connecting shaft passing through the through hole of the extraction chamber. The connecting shaft is provided with a connecting portion that is in interference fit with the housing. The spring is located above the connecting portion.

[0009] In some embodiments, the housing is symmetrically provided with two positioning portions. The positioning portions are provided with protruding portions, and the connecting portion is provided with grooves that cooperate with the protruding portions.

[0010] In some embodiments, the inner wall of the opening of the extraction chamber is designed to be inclined.

[0011] In some embodiments, the inner wall of the extraction chamber is provided with multiple inclined surfaces for transition.

[0012] This application also provides a coffee machine, including a coffee machine body, and the coffee machine body is provided with a coffee funnel cake discharging device as described above.

[0013] The beneficial effects of this application are as follows:

[0014] Since the extraction chamber can move downward relative to the outer shell, during the downward movement, the powder cake adhered to the extraction chamber also has the power to move downward. However, due to the resistance of the filtering component, the powder cake is separated from the extraction chamber. In addition, the downward moving extraction chamber is equivalent to pushing the filtering component upward, thereby completing the cake discharging action. Description of the Drawings

[0015] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings required for the description of the embodiments will be briefly introduced below.

[0016] Figure 1 It is a schematic structural diagram of an embodiment of the present invention. Detailed Embodiments

[0017] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0018] Please refer to Figure 1 As shown, a coffee funnel cake discharging device includes an outer shell 1 and an extraction chamber 2 that moves relative to the outer shell 1. The outer shell 1 is provided with a water outlet nozzle 3, the extraction chamber 2 is provided with a through hole 4 communicating with the water outlet nozzle 3, and further includes a filtering component disposed within the extraction chamber 2. The middle part of the filtering component passes through the extraction chamber 2 and is connected to the outer shell 1. A spring 5 is provided between the middle part of the filtering component located between the extraction chamber 2 and the outer shell 1.

[0019] When the extraction chamber moves downward, the spring is compressed. Under the limiting action of the filtering component, the powder cake is separated. Then the spring resets to drive the extraction chamber to reset, making it more convenient to discharge the cake. When the user pours out the powder cake after coffee extraction, the entire funnel can also be held upside down, or placed upside down in a cleaning pool or on the ground, and then gently tap the outer shell of the water outlet nozzle to make it move downward, driving the filter screen component to move downward simultaneously to push out the coffee powder cake, thereby realizing the separation of the powder cake from the inner part of the funnel, reducing the adhesion of the powder cake, and enabling the powder cake to be easily poured out without the need to laboriously knock the funnel.

[0020] In this embodiment, the filtering component includes;

[0021] Filter screen 6;

[0022] Filter screen support 7, the filter screen support 7 is provided with a connecting shaft 8 passing through the through hole of the extraction chamber 2, the connecting shaft 8 is provided with a connecting portion 9 that is in interference fit with the housing 1, and the spring 5 is located above the connecting portion 9.

[0023] The connecting portion mainly functions to limit the spring and connect the water outlet nozzle housing through a snap position. In the normal non-extraction and extraction states, the filter screen support closely adheres to the bottom plane of the funnel under the action of the spring force. After removing the funnel and flipping it to gently press the upper end surface of the funnel, the force of the hand will overcome the elastic force of the spring, and the funnel will retract, which is equivalent to the filter screen sliding upward, and the powder cake will be pushed loose upward synchronously. Because the inner wall of the funnel has an inclination, wider at the top and narrower at the bottom, the powder cake can be easily poured out when the funnel is flipped. The water outlet nozzle sleeve is fixed on the retaining ring through a convex block and is relatively easy to disassemble by pulling downward forcefully, which is convenient for users to disassemble and clean the filter screen support frame, the funnel, and the residue inside the water outlet nozzle housing.

[0024] In this embodiment, the housing 1 is symmetrically provided with two positioning portions 10, the positioning portions 10 are provided with protruding portions 11, and the connecting portion 9 is provided with grooves that cooperate with the protruding portions 11, which is convenient for disassembly and cleaning.

[0025] In this embodiment, the inner wall of the opening of the extraction chamber 2 is designed with an inclined surface, so that the extraction chamber is narrower at the bottom and wider at the top, which is more convenient for pouring out the powder cake.

[0026] In this embodiment, the inner wall of the extraction chamber 2 is provided with multiple sections of inclined surfaces for transition. In order to achieve a better cake removal effect, the inner wall of the coffee funnel has three or more draft angles, or it can also be connected by multiple arcs. The purpose is to effectively break away from the adhesion force of the wall surface when the powder cake is pushed upward by a certain distance, making it easier to achieve easy cake removal. The optimal solution is that the draft angle at the bottommost end is 0.3 - 0.6 degrees. If it is too large, it will be easy to leave coffee residues in the gaps and difficult to clean. The draft angle in the middle section is 5 - 15 degrees, and the draft angle at the top is 0.3 - 0.6 degrees. If the draft angle of this section is too large, it will not be able to ensure a high-pressure and high-temperature environment during coffee extraction.

[0027] This application also provides a coffee machine, including a coffee machine body, and the coffee machine body is provided with a coffee funnel cake removal device as described above.

[0028] The above are only the preferred embodiments of this application and are not used to limit the scope of implementation of this application. Other applications with the same or similar principles and basic structures as this application are within the protection scope of this application.
