[0024] Reference Figures 1 to 4 The extraction handle 10 of this utility model embodiment includes a handle body 100, a needle body 200 and a powder bowl 300. The handle body 100 is provided with an extraction tank 110, and the bottom of the extraction tank 110 is provided with a liquid outlet 120. The opening of the extraction tank 110 forms a water inlet 130. The needle body 200 is provided on the handle body 100 and located at the bottom of the extraction tank 110, and the needle body 200 extends toward the opening of the extraction tank 110. The powder bowl 300 can be installed on the handle body 100 or detached from the handle body 100. The powder bowl 300 is provided with a raw material tank 310, and the bottom wall of the raw material tank 310 is provided with a filter screen 320. When the powder bowl 300 is installed on the handle body 100, the powder bowl 300 is located in the extraction tank 110, and the powder bowl 300 and the needle body 200 are arranged at intervals. The extraction handle 10 has a raw material extraction state and a capsule extraction state. In the raw material extraction state, the powder bowl 300 is installed on the handle body 100. In the capsule extraction state, the powder bowl 300 is detached from the handle body 100.

[0025] When extraction using beverage capsules is required, switch the extraction handle 10 to capsule extraction mode, i.e., remove the powder bowl 300, and then place the beverage capsule directly into the extraction tank 110. During extraction, the needle 200 can puncture the liquid outlet side of the beverage capsule, and hot water is injected into the beverage capsule through the water inlet 130. The beverage flows out from the liquid outlet side of the beverage capsule and finally flows into the collection container through the liquid outlet 120 of the extraction handle 10, thus realizing extraction using beverage capsules. When extraction using solid raw materials is required, switch the extraction handle 10 to raw material extraction mode, and place the powder... The bowl 300 is installed on the extraction handle 10. At this time, the bottom of the bowl 300 is located in the extraction tank 110, and the needle body 200 does not interfere with the bowl 300. Then, the solid raw material is placed into the raw material tank 310 of the bowl 300, and hot water is injected into the raw material tank 310 from the water inlet 130. Then, the beverage flows into the collection container from the liquid outlet 120 of the extraction handle 10 through the filter screen 320, thereby realizing the extraction of solid raw materials. The extraction handle 10 described above can be used for the extraction of beverage capsules or solid raw materials, with good versatility, and the beverages made can be diversified.

[0026] Specifically, the liquid outlet side of the beverage capsule can be punctured directly by the needle body 200 during insertion, or the bottom of the beverage capsule can be punctured by the needle body 200 under water pressure when the water volume inside the beverage capsule reaches a certain level.

[0027] In the embodiments, reference is made to Figure 2 The needle body 200 is detachably mounted on the handle body 100. The handle body 100 is equipped with a locking element that can lock or unlock the position of the needle body 200 relative to the handle body 100. The powder bowl 300 is securely placed on the handle body 100 by the support block 330 stacked on the support surface 140, making installation and disassembly relatively convenient. Furthermore, the support block 330 is annular, allowing the powder bowl 300 to fully overlap with the support surface 140, achieving a sealed fit.

[0028] Specifically, when the beverage capsule is placed into the extraction tank 110 of the handle body 100, the outer peripheral flange of the beverage capsule also overlaps with the support surface 140 to form a sealed fit.

[0029] In the embodiments, reference is made to Figure 2 The needle body 200 is detachably mounted on the handle body 100. The handle body 100 is provided with a locking member that can lock or unlock the position of the needle body 200 relative to the handle body 100. In the above-mentioned extraction handle 10, the handle body 100 and the needle body 200 are processed separately, then assembled and the needle body 200 is fixed by the locking member. The manufacturing of the parts is relatively simple, and the needle body 200 can be disassembled and replaced when damaged.

[0030] Specifically, the needle body 200 is inserted into the handle body 100, and the locking element is a threaded fastener, which locks and fixes the needle body 200 to the handle body 100; the needle body 200 can be removed when the threaded fastener is loosened. It is conceivable that in some other embodiments, the locking element may also be a plug-in block, etc., which fixes the needle body 200 by plugging and snapping.

[0031] Optionally, in some embodiments, the needle body 200 is provided with a flow guide groove, so that when the needle body 200 pierces the beverage capsule, the beverage can flow out smoothly through the flow guide groove, thereby improving the beverage outflow efficiency.

[0032] In the embodiments, reference is made to Figure 2 and Figure 3 It also includes a pressure valve assembly 400, which is disposed on the handle body 100 and opposite to the liquid outlet 120. The pressure valve assembly 400 can close or open the liquid outlet 120. After hot water is injected into the powder bowl 300 or beverage capsule through the water inlet 130, the pressure in the extraction tank 110 gradually increases. When the pressure in the extraction tank 110 is low, the pressure valve assembly 400 keeps the liquid outlet 120 closed, so that the liquid in the extraction tank 110 is in the optimal extraction pressure range, and the extraction is more complete; when the pressure in the extraction tank 110 reaches a certain level, the fluid in the extraction tank 110 pushes open the pressure valve assembly 400, thereby allowing the beverage to flow out from the liquid outlet 120.

[0033] In the embodiments, reference is made to Figure 2 and Figure 3 The pressure valve assembly 400 includes a leak holder 410, an elastic element 420, and a valve core 430. The handle body 100 is provided with a liquid outlet 150, which is connected to the bottom of the extraction tank 110 through a liquid outlet 120. The leak holder 410 is installed on the handle body 100. The valve core 430 is disposed in the liquid outlet 150 and can move along the axis of the liquid outlet 150. The elastic element 420 is disposed between the leak holder 410 and the valve core 430 and can drive the valve core 430 to block the liquid outlet 120.

[0034] Under normal conditions, the elastic element 420 drives the valve core 430 to block the outlet 120. When the pressure inside the extraction tank 110 increases to the point where it can overcome the elastic force of the elastic element 420, causing the elastic element 420 to be compressed and push open the valve core 430, the liquid inside the extraction tank 110 can then flow out through the outlet 120. After the liquid has flowed out, the elastic element 420 drives the valve core 430 to reset and re-block the outlet 120. The pressure valve assembly 400 described above has a simple structure and good performance.

[0035] Specifically, the elastic element 420 is a spring. Alternatively, the elastic element 420 can also be, for example, a sheet or a silicone block, etc., which is not limited here.

[0036] In the embodiments, reference is made to Figure 2 and Figure 3 The nozzle holder 410 is installed in an adjustable position on the handle body 100 along the axis of the outlet hole 150 to adjust the elastic force of the elastic element 420 on the sealing element, thereby adjusting the outlet pressure in the extraction tank 110 to suit the needs of different extraction formulas or flavors.

[0037] In the embodiments, reference is made to Figure 2 and Figure 3 The handle body 100 has a stud portion along the axis of the outlet hole 150, and the outlet hole 150 is located on the stud portion. The leak holder 410 has a threaded hole, and the stud portion is threaded into the threaded hole. By rotating the leak holder 410 through the threaded connection, the position of the leak holder 410 relative to the handle body 100 along the axis of the outlet hole 150 can be adjusted, thereby achieving stepless or stepped pressure regulation, providing good adjustment flexibility. The leak holder 410 is installed by a threaded connection, which allows the pressure valve assembly 400 to be disassembled for easy maintenance and cleaning.

[0038] It is conceivable that in other embodiments, the nozzle holder 410 can also be installed on the handle body 100 in other ways and achieve an adjustable position. For example, the nozzle holder 410 can be slidably inserted into the handle body 100, and the handle body 100 can be provided with a plurality of first pin holes arranged along the sliding direction of the nozzle holder 410. The nozzle holder 410 is provided with a second pin hole, and a pin is inserted into the second pin hole and one of the first pin holes. By adjusting the pin inserted into different first pin holes, the position of the nozzle holder 410 can be adjusted.

[0039] In the embodiments, reference is made to Figure 2 and Figure 3 The liquid outlet 150 is a conical orifice, with its smaller end connected to the liquid outlet 120. This allows for adaptive adjustment of the liquid outlet speed based on the pressure within the extraction tank 110. When the pressure within the extraction tank 110 is high, the valve core 430 is pushed open a greater distance, providing more space for liquid to flow out of the liquid outlet 150. Conversely, when the pressure within the extraction tank 110 is low, the valve core 430 is pushed open a smaller distance, providing less space for liquid to flow out of the liquid outlet 150.

[0040] In the embodiments, reference is made to Figure 4 The spout holder 410 is provided with two liquid outlet channels, which can simultaneously divert beverages into two collection containers. Optionally, the spout holder 410 may also be provided with one or more liquid outlet channels.

[0041] The pressure valve in this design is a mechanical pressure valve. It is conceivable that in other embodiments, the pressure valve assembly 400 could also be an electrically controlled pressure valve, or other types of pressure valve assemblies 400, which are not limited here.

[0042] Specifically, the pressure valve assembly 400 is universal for both beverage capsules and solid raw materials, which helps to simplify the equipment structure and reduce equipment costs.

[0043] Reference Figure 4 This application also discloses an extraction device, including an extraction seat 20 and an extraction handle 10. The extraction seat 20 is provided with a water injection structure; the extraction handle 10 is detachably inserted into the extraction seat 20, with the water inlet 130 opposite to the water injection structure. By inserting the handle 10 directly into the extraction seat 20, the installation and disassembly structure is simple, and the use is convenient and efficient.

[0044] Specifically, the water injection structure can include an injection needle and a dispensing plate. The injection needle can pierce the water inlet side of the beverage capsule and inject hot water into the beverage capsule; the dispensing plate can evenly spray hot water into the powder bowl 300 to improve the extraction effect.

[0045] Specifically, a sealing step or a sealing pressing surface can be provided at the opening of the extraction tank 110 to facilitate the sealing fit between the extraction handle 10 and the extraction seat 20.

[0046] Specifically, a sealing structure such as a sealing ring can be provided around the opening of the extraction tank 110 to prevent overflow; a sealing structure such as a sealing ring can also be provided between the handle assembly and the pressure valve assembly 400 to prevent leakage. Optionally, the nozzle holder 410 of the pressure valve assembly 400 can also be disassembled, and the internal valve core 430 or elastic element 420 can be replaced to adapt to different extraction formulas or flavor requirements.

[0047] It should be understood that beverage capsules on the market can be either puncture-type beverage capsules punctured by a needle body 200 or self-exploding beverage capsules. The extraction handle 10 of this application can be used for both puncture-type and self-exploding beverage capsules. Those skilled in the art can make a reasonable choice according to actual needs.
