[0001] The utility model relates to the technical field of coffee machine accessories, and in particular to an extraction handle. Background Art

[0002] The ground coffee powder of the semi-automatic coffee machine is placed in the receiving chamber of the extraction handle, the coffee powder is flattened with a powder distributor, and then compacted with a powder hammer, and finally the handle is locked on the brewing outlet of the coffee machine, and high-temperature hot water is directly used to immerse the coffee powder through the outlet for extraction, and the extracted coffee liquid flows out from the bottom of the handle. The commonly used coffee extraction handle is shown in CN202221082986.8, which includes a metal head connected to the coffee machine and a grip. Lugs are arranged on the outer peripheral wall of the metal head, and are fixed to the card slot of the water outlet of the coffee machine through the lugs. The metal head is a hollow cylinder, and the upper end face can be placed on the powder bowl, and the lower end face is connected to the diverter nozzle. When the coffee powder is coarse or the amount of coffee powder is small, the pressure of the coffee powder extraction will be insufficient, resulting in insufficient coffee extraction and affecting the taste of the coffee.

[0003] Conventional tea extraction handles usually have a pressure valve at the bottom of the metal head with a spring accessory installed inside the pressure valve. The brewed and extracted tea will pass through the spring and then flow out from the water outlet of the pressure valve, which is inconvenient to clean and unhygienic to use for a long time.

[0021] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. The components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] like Figure 1-4 As shown, an extraction handle of the utility model comprises a bowl body 1, a funnel 2, a water spout 3 and a handle 4. The bowl body 1 is embedded in the funnel 2. The bowl body 1 is used to hold coffee powder or tea leaves. The bottom of the bowl body 1 is provided with a plurality of filter holes 11. The funnel 2 is provided with a plurality of lugs 23. The coffee machine is provided with an inlet adapted to the lugs 23. The extraction handle is connected to the brewing head of the coffee machine through the lugs 23. The funnel 2 is connected to the handle 4. A connecting portion 22 and a plurality of water leakage holes 212 are provided at the bottom of the funnel 2. The water leakage holes 212 penetrate the connecting portion 22. The connecting portion 22 is detachably connected to the water spout 3. The water spout 3 is provided with a plurality of water outlet holes 31.

[0024] A seal 5, a first magnet 6 and a second magnet 7 are installed in the water outlet 3 from top to bottom. The seal 5 is used to seal the water leakage hole 212. The magnetic poles of the first magnet 6 and the second magnet 7 are in opposite directions, that is, when the upper end of the first magnet 6 is the S pole and the lower end is the N pole, the upper end of the second magnet 7 is the N pole and the lower end is the S pole. Since the magnetic poles of the ends of the first magnet 6 and the second magnet 7 that are close to each other are the same, they repel each other and generate a pressure of about 7 bar.

[0025] The extraction handle of the utility model places coffee powder or tea leaves in the bowl body 1, and installs the handle on the brewing head of the coffee machine. A sealed brewing chamber is formed in the bowl body 1, and hot water flows from the brewing head into the bowl body 1 to extract the coffee powder or tea leaves. Due to the mutual repulsion between the first magnet 6 and the second magnet 7, the seal 4 is attached to the bottom of the connecting portion 22 to block the water leakage hole 212, and no liquid flows out at this time. As the coffee machine continuously increases the pressure on the bowl body 1 of the handle, when the pressure is greater than the repulsive force between the two magnets, the seal 4 and the first magnet 6 are squeezed and moved downward, causing the seal 4 to detach from the connecting portion 22, and the coffee liquid or tea soup flows out from the water leakage hole 212, and then flows out from the water outlet hole 31 on the water outlet 3, thereby completing the entire extraction process. The extraction handle of the utility model can ensure a pressure of 7-8 bar during extraction, and can also ensure a minimum extraction pressure for coffee extraction. It is suitable for extracting coffee powder of different coarseness and powder amount, and improves the extraction success rate. In addition, there is no spring component inside the extraction handle, and it is easy to disassemble and clean.

[0026] Further, such as Figure 2 and 4 As shown, the connection part 22 is connected to the water spout 3 by a threaded connection. The water spout 3 is U-shaped, with an opening 32 at the upper end and a sealed bottom. A plurality of water outlet holes 31 are provided on the side wall of the water spout 3 to prevent the coffee liquid or tea soup from leaking out when the seal 4 moves downward due to the slight pressure value. As the seal 4 continues to move downward, when the pressure value reaches a preset value, the water outlet holes 31 on the side wall can be connected to the water leakage hole 212. In this embodiment, the water spout 3 is made of polished stainless steel.

[0027] Furthermore, in the present embodiment, the sealing member 4 is in the shape of a disc and is made of silicone. The radius of the sealing member 4 is greater than the radius of the connecting portion 22 , that is, the sealing member 4 can block the bottom of the connecting portion 22 .

[0028] like Figure 1-2 As shown, the funnel 2 is provided with an extraction cavity 21, and a groove 211 is provided at the bottom of the extraction cavity 22. The water leakage hole 212 is arranged at the groove 211, which has a diversion effect on the coffee liquid or tea soup flowing out of the filter hole 11 of the bowl body 1 after brewing, and prevents excess liquid from being left at the bottom of the funnel. The bowl body 1 is provided with a curling edge, and the bowl body 1 is embedded in the funnel 1 through the curling edge, and the height of the bowl body 1 is less than the height of the funnel 2, so that when the bowl body 1 is embedded in the extraction cavity 22 of the funnel 1, there is a certain distance between the bottom of the bowl body 1 and the bottom of the extraction cavity 22, which facilitates the coffee liquid or tea soup to flow out from the bottom of the bowl body 1, and can increase the flow rate.

[0029] When the extraction handle of the utility model needs to be cleaned, the water spout 3 is disassembled from the connecting portion 22, the sealing member 4, the first magnet 6 and the second magnet 7 in the water spout 3 are taken out, and then the bowl body 1 is removed from the funnel 2, and each component can be cleaned.

[0030] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0031] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
