Description

Technical Field

[0001] This utility model relates to the field of coffee preparation equipment, and in particular to a coffee pressure filter pot. Background Technology

[0002] Chinese Patent No. CN206044375U discloses a stainless steel vacuum coffee press, which includes an outer shell, an inner liner, a top cover, and a coffee press assembly that is slidably disposed in the middle of the top cover. The coffee press assembly includes a filter plate and a pull rod fixed thereon. The pull rod passes through a hollow tube in the middle of the top cover and extends to the outside of the top cover, and a handle is fixed to its end.

[0003] The inner and outer shells are welded together to form a double-layered kettle structure. When brewing, place the coffee powder at the bottom of the inner liner, pour in hot water and brew for 3-5 minutes. Then, insert the filter plate and press down the lever. Because the filter plate is in sealed contact with the inside of the inner liner, it can press the coffee liquid below to the top of the filter plate. The filter residue is still at the bottom of the inner liner. At this point, pour out the coffee liquid above the filter plate and you can enjoy your coffee.

[0004] Existing coffee press components have a filter screen, with the coffee liquid located above the press component and the filter residue located at the bottom of the pot. This invention provides a new coffee press pot that achieves separation of liquid and residue. Utility Model Content

[0005] In contrast to the conventional structure of existing coffee presses, where the pressing component moves up and down within the pot body for pressing, and the coffee liquid is located above the pressing component after pressing, while the filter residue is located between the pot body and the pressing component, this invention provides a new coffee press that achieves separation of liquid and residue.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A coffee press includes a pot body with an inner liner inserted inside. The inner liner includes a cylindrical inner body and a filter element located at the bottom of the inner body. A pressure assembly moves up and down inside the inner body. The pressure assembly includes a pressure element that moves within the inner body and, as it descends, can squeeze the liquid below from the filter element into the pot body, and a pull rod with one end connected to the upper end of the pressure element and the other end extending out of the pot body.

[0008] By adopting the above solution, an inner liner is added, with the filter component at the bottom of the inner liner. The pressure filter assembly moves and seals inside the inner liner and increases the pressure below as it descends, pressing the coffee liquid from the filter component into the pot body. This is significantly different from the conventional structure where the coffee liquid is located above the pressure filter assembly. This operation method can improve the ease of cleaning the pot body to a certain extent.

[0009] Preferably, the filtering component includes a connector detachably connected to the inner chamber and a filter for filtering coffee.

[0010] With the above solution, the connector in the filter element is detachably connected to the filter body, which makes it easier to remove the filter residue and further improves the ease of cleaning.

[0011] Preferably, the filter element is a rigid filter screen that is integrally formed with the connector and covers the bottom of the chamber.

[0012] Preferably, the filter element includes a support base integrally formed with the connector and covering the bottom of the inner tank, a rigid filter screen or flexible filter paper built into the bottom of the support base, and a number of water passage holes provided at the bottom of the support base. The bottom of the inner tank is inserted into the connector and presses the rigid filter screen or flexible filter paper against the support base.

[0013] Using the above solutions, the filter structures described above can all achieve the functions of supporting the bottom of the inner pot and filtering coffee liquid into the pot.

[0014] Preferably, the connector is snap-fitted or screwed into the inner tube.

[0015] Using the above methods, either snap-fit ​​or screw-fit can achieve a detachable connection between the connector and the inner tube.

[0016] Preferably, the bottom of the connector extends downward to form a raised part that contacts the bottom of the pot body, and the raised part has a water channel for the coffee liquid filtered through the water passage to enter the pot body.

[0017] By adopting the above solution, the setting of the shim can make the inner liner contact the bottom of the pot body while allowing the coffee liquid to be smoothly filtered into the pot body. The inner liner is supported by the pot body, and the downward pressure of the filter assembly will not cause the inner liner to fall, ensuring the stable filtration of the coffee liquid.

[0018] Preferably, a sealing ring is elastically fitted onto the outer wall of the upper end of the inner liner, and the outer wall of the sealing ring is elastically inserted into the opening of the kettle body.

[0019] With the above solution, since the inner liner is in contact with the bottom of the kettle body, the inner liner can be inserted into the inner wall of the kettle body using the damping formed by the sealing ring, making the assembly or disassembly of the inner liner quicker.

[0020] Preferably, the opening of the pot is covered with a lid, and the upper end of the lever passes through the central hole of the lid and extends to the outside of the lid.

[0021] Using the above design, the lid can block hot air and guide the pull rod.

[0022] Preferably, a gripping block is fixed to the upper end of the pull rod.

[0023] The above scheme facilitates the rapid raising and lowering of the lever by applying force.

[0024] Preferably, the pressure component includes a pressure plate and an elastic sealing element that covers the pressure plate and whose outer ring wall elastically seals against the inner wall of the bladder.

[0025] Using the above solution, the encapsulated elastic seal can further increase the sealing performance when the pressure element is pressed down, ensuring sufficient air pressure to force the coffee liquid to filter downwards.

[0026] This utility model, by adopting the above technical solutions, has significant technical effects: The newly added inner liner is a pull-out bottom-contact type, which allows the inner liner to be directly and elastically inserted into the pot body, making assembly, disassembly, and cleaning more convenient; the inner liner body and the bottom filter component are detachable, facilitating the removal of filter residue and further improving cleaning convenience; the pressure filter assembly is located inside the inner liner, allowing the coffee liquid to be pressed and filtered into the pot body from the bottom, unlike the conventional structure where the coffee liquid is located above the pressure filter assembly. This method avoids filter residue adhering to the bottom of the pot body, facilitating cleaning. This coffee pressure filter pot has a novel structure and is easy to clean.
