[0001] The utility model relates to the field of coffee machines, in particular to an automatic coffee cake discharging device for a coffee funnel. Background Art
[0002] A coffee machine is an electrical device used 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 manually and removes residues manually; 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, and powder pouring, and brews coffee according to scientific data and procedures. With the improvement of living standards, coffee has gradually become a common beverage in people's lives. Due to the accelerating pace of life, coffee machines that can quickly brew coffee are favored by people. Generally, the above-mentioned coffee machines are provided with 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 by pouring operation after being soaked in hot water. Content of the Utility Model
[0003] To solve the above problems, the present technical solution provides an automatic coffee cake discharging device for a coffee funnel.
[0004] To achieve the above purpose, the present technical solution is as follows:
[0005] An automatic coffee cake discharging device for a coffee funnel includes a housing. The housing is provided with a water outlet nozzle. An extraction chamber is arranged inside the housing. The extraction chamber is provided with a dripping hole communicated with the water outlet nozzle. A filtering component capable of moving up and down inside the extraction chamber is arranged inside the extraction chamber. The filtering component is provided with a first sealing part passing through the dripping hole, so that when the filtering component rises, the first sealing part blocks the dripping hole, and when the filtering component moves down, the dripping hole is opened.
[0006] The opening of the extraction chamber is inclined outward.
[0007] In some embodiments, the filtering component includes:
[0008] A filter screen;
[0009] A filter screen support for supporting the filter screen. The filter screen support is provided with a through hole communicated with the dripping hole;
[0010] A connecting shaft connected to the filter screen support and passing through the dripping hole;
[0011] A spring sleeved on the outer periphery of the connecting shaft, and the spring is installed above the dripping hole.
[0012] In some embodiments, a plurality of surrounding portions for surrounding the spring are provided at the dripping hole, and a gap is provided between two adjacent surrounding portions.
[0013] In some embodiments, the lower end surface of the extraction chamber is inclined with the dripping hole as the center.
[0014] In some embodiments, when viewed in cross-section, the outer side of the first sealing portion is inclined.
[0015] In some embodiments, a second sealing portion is provided between the outer end of the filter screen bracket and the inner wall of the extraction chamber.
[0016] In some embodiments, the opening position of the through hole is opposite to the inclined portion of the lower end surface of the extraction chamber.
[0017] The beneficial effects of the present application are as follows:
[0018] During extraction, the powder cake is placed in the extraction chamber. As the pressure increases, the filter assembly moves downward, and then the first sealing portion moves downward accordingly, thereby opening the dripping hole. After the powder cake is extracted, it drips from the dripping hole. Until the pressure decreases, the filter assembly moves upward to block the dripping hole. Finally, the design with the lower part being narrower and the upper part being wider at the opening can easily pour out the powder cake, which is automatic when the user uses it and improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
[0019] 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.
[0020] Figure 1 is the structural schematic of the embodiment of the present invention Figure 1 (extraction completed);
[0021] Figure 2 is the structural schematic of the embodiment of the present invention Figure 2 (extracting). DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clear, 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.
[0023] Please refer to Figure 1-2As shown in the figure, a coffee funnel automatic cake discharging device includes a housing 1. The housing 1 is provided with a water outlet nozzle 2. An extraction chamber 3 is arranged inside the housing 1. The extraction chamber 3 is provided with a dripping hole 4 communicating with the water outlet nozzle 2. A filtering component capable of moving up and down inside it is arranged in the extraction chamber 3. The filtering component is provided with a first sealing portion 5 passing through the dripping hole 4. When the filtering component rises, the first sealing portion 5 blocks the dripping hole 4. When the filtering component moves down, the dripping hole 4 is opened.
[0024] The opening of the extraction chamber 3 inclines outward.
[0025] During extraction, the powder cake is placed in the extraction chamber. As the pressure increases, the filtering component moves down, and then the first sealing portion moves down accordingly, thus opening the dripping hole. After the powder cake is extracted, it drips from the dripping hole until the pressure decreases. Then the filtering component moves up, thus blocking the dripping hole. Finally, with the design of the lower narrow and upper wide at the opening, the powder cake can be easily poured out. Through this optimization, the user operation is automatic, improving the user experience.
[0026] In this embodiment, the filtering component includes:
[0027] A filter screen 6;
[0028] A filter screen support 61 for supporting the filter screen 6. The filter screen support 61 is provided with a through hole 62 for communicating with the dripping hole 4;
[0029] A connecting shaft 63 is connected to the filter screen support 61 and passes through the dripping hole 4;
[0030] A spring 64 is sleeved on the outer periphery of the connecting shaft 63, and the spring 64 is installed above the dripping hole 4.
[0031] In the normal unextracted state, the filter screen support is lifted by a certain distance under the action of the spring force. In the brewing and extraction state, under the dual action of the brewing head and water pressure, the filter screen support closely adheres to the bottom plane of the funnel under pressure, and the sealing port is opened. The coffee liquid flows out from the hole into the lower water outlet nozzle. When the extraction is completed and the pressure is relieved, the filter screen slides upward under the action of the spring force, and the powder cake is simultaneously pushed up and loosened. 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 inverted;
[0032] A silica gel sealing limit ring is sleeved on the filter screen support shaft. Its function is to rise under the action of the spring force and block the liquid outlet after the extraction is completed, effectively reducing the phenomenon of continuous dripping after extraction, and also playing a limiting role.
[0033] In this embodiment, a plurality of surrounding portions 7 for surrounding the spring 64 are provided at the dripping hole 4. There is a gap between two adjacent surrounding portions 7 for fixing the spring, and the coffee can flow into the dripping hole through the gap.
[0034] In this embodiment, the lower end surface of the extraction chamber 3 is inclined with the dripping hole 4 as the center, ensuring that the coffee can enter the dripping hole completely through the inclined surface and preventing it from remaining in the chamber.
[0035] In this embodiment, when viewed in cross-section, the outer side of the first sealing portion 5 is inclined, serving as a guiding function.
[0036] In this embodiment, a second sealing portion 8 is provided between the outer end of the filter screen support 61 and the inner wall of the extraction chamber 3 to prevent leakage.
[0037] In this embodiment, the opening position of the through hole 62 is opposite to the inclined portion of the lower end surface of the extraction chamber 3, ensuring that the dripping coffee can completely fall on the inclined surface and then enter the hole.
[0038] Specifically, the internal water outlet nozzle can be used alone without sleeving the telescopic water outlet nozzle. Vertical long grooves are opened on both sides of the funnel, and there are 4 protruding transverse ribs in the middle section to limit the sliding positions of the telescopic water outlet nozzle up and down. The liftable water outlet nozzle slides up and down in the groove on the side of the funnel and is fixed at one position. It can also be easily removed, and the silicone sealing limit ring is also easy to disassemble, facilitating users to clean the residue in the filter screen support frame and the corner of the funnel.
[0039] The above is only the preferred embodiment of the present application and is not used to limit the scope of implementation of the present application. Other embodiments with the same or similar principles and basic structures as the present application are within the protection scope of the present application.
