Description

Technical Field

[0001] This utility model relates to the field of beverage preparation equipment, and in particular to a hydraulic filter assembly and a filter cup. Background Technology

[0002] Originally an important component of French presses, pressure filter components are now occasionally used in water cups and other vessels to achieve the effect of pressure filtering brewing substances. The structure of a pressure filter component can be found in Chinese Patent Publication No. CN211049116U, entitled "A Pressure Filter Component and a Coffee Pressure Filter." The pressure filter component includes a vertically arranged pressure rod and a filter screen. The filter screen is usually a fine mesh made of materials such as metal or nylon. The edge of the filter screen is sealed to the inner wall of the pot. By moving the pressure rod up and down, the filter screen can apply pressure to the brewing particles in the lower chamber, accelerating the decomposition or extraction of the brewing particles and allowing the lower solution to pass more smoothly through the filter screen into the upper chamber.

[0003] Because French presses have a spout for pouring liquids, while regular cups cannot have a spout to ensure a proper seal, it is essential to improve the convenience of drinking from French press cups with pressure components. Utility Model Content

[0004] This invention addresses the inconvenience of using existing pressure filter components in water cups, and its primary objective is to provide a pressure filter component with a built-in liquid dispensing function.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] The hydraulic filter assembly includes a pressure rod and a filter screen assembly fixed to the bottom of the pressure rod. The pressure rod is a blind tube with an upward opening. An inlet hole communicating with the inside of the pressure rod is provided on the pressure rod above the filter screen assembly.

[0007] The above solution replaces the solid structure of the pressure rod with a blind tube structure. The water inlet is located above the filter assembly, and the upper end of the pressure rod is the water outlet. The advantage of this design is that when the pressure rod moves up and down, the filter assembly can still filter the brewing particles below. The residue-free beverage is located above the filter assembly. You can directly suck out the residue-free beverage by sucking the upper end of the pressure rod, achieving the effect of direct drinking.

[0008] Preferably, the upper end of the lever is provided with a handle that lifts the lever while preventing the head of the lever from getting dirty.

[0009] Using the above solution, conventional French presses have a handle at the top of the press rod to facilitate the operator in raising and lowering the press rod. In this solution, the handle is not only easy to hold but also prevents the operator from touching the press rod, ensuring the hygiene of the drinking water.

[0010] Preferably, the handheld part includes a base that can be interference-fitted to the upper end of the pressure bar, and a drinking spout is provided on the upper end of the base.

[0011] Preferably, the spout is an integrated spout that is integrally set with the pressure rod or a separate spout that is detachable from the base and communicates with the inside of the pressure rod.

[0012] Preferably, the drinking spout is a hard spout or a flexible spout.

[0013] Preferably, the drinking spout is straw-shaped, duckbill-shaped, or nipple-shaped.

[0014] Preferably, the base is equipped with a cover that can conceal or reveal the drinking spout.

[0015] Preferably, one end of the cover is hinged to the base and the other end is fitted to the base by snap-fit ​​or interference fit.

[0016] By adopting the above solution, the lid can completely cover the drinking spout, further increasing the level of hygiene protection.

[0017] Preferably, the drinking spout is an elastic straw with a bend, and the cap has a protruding pressure plate that presses against the elastic straw to limit the flow of water from the elastic straw when the cap is closed.

[0018] By adopting the above solution, the tablet compression setting can prevent water from leaking out accidentally.

[0019] The second objective of this utility model is to provide a filter press cup, including a cup body and a cup cover screwed to the upper end of the cup body. An inner cover is sealed and inserted into the upper end of the cup body. The aforementioned hydraulic filter assembly is provided inside the cup body. The upper end of the pressure rod is sealed and passes through the inner cover and is located between the inner cover and the cup cover.

[0020] By adopting the above solution, a direct-drinking hydraulic filter assembly can be applied to a filter cup. After opening the lid and performing the filter press, the water can be consumed directly, making the operation very convenient.

[0021] This utility model, by adopting the above technical solutions, has significant technical effects: by setting the pressure rod in the conventional filter press assembly as a blind tube with an inlet hole, it can be directly drunk after filter press without pouring, thus improving the convenience of drinking; by setting a handle with a cover, the drinking spout can be completely hidden, significantly improving the hygiene level of drinking; the drinking spout can be integrated with or separated from the pressure rod, and can be made of rigid or elastic material, and can be shaped like a straw, a duckbill, or a nipple to meet the needs of direct drinking.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Filter press cup, refer to Figures 1-3 As shown, the device includes a cup body 1. The outer wall of the opening of the cup body 1 is provided with external threads, and a cup lid 2 is screwed onto the external threads. An inner cover 10 overlaps at the opening of the cup body 1. The inner cover 10 is partially elastically sealed and inserted into the opening. A hydraulic filter assembly is provided inside the cup body 1. The hydraulic filter assembly includes a vertically arranged pressure rod 3 and a filter screen assembly 4 fixed to the bottom of the pressure rod 3 and sealingly lifting and lowering with the inner wall of the cup body 1. In this solution, the assembly method of the filter screen assembly 4 and the pressure rod, as well as the structure of the filter screen assembly 4, are not improved and are existing technologies. The specific structure will not be described in detail.

[0028] The pressure rod 3 is configured as a blind tube with the opening facing upward. A water inlet hole 301 is provided on the pressure rod 3 above the filter screen assembly 4 and communicates with the inside of the pressure rod 3. The water inlet hole 301 is preferably located at one end close to the filter screen assembly 4.

[0029] After the upper end of the pressure rod 3 passes through the inner cover 10, a hand-held part is provided at its end. The hand-held part includes a base 6 and a cover 7 hinged to the base 6. The lower end of the cover 7 has a protruding insert section for the upper end of the pressure rod 3 to be inserted through an interference fit. A drinking spout 5 is elastically inserted into the cover 7 through an interference fit. The drinking spout 5 is an elastic straw with a bend and is made of food-grade silicone. The end of the cover 7 away from the hinge end has a protruding fastener 9 that can be interference fit against the outer ring wall of the base 6. The cover 7 has a protruding pressure piece 8 that presses against the elastic straw to cut off the flow of water inside when the cover 7 and the base 6 are closed.

[0030] The procedure for brewing beverages using a filter press cup is as follows:

[0031] Open the cup lid 2, take out the inner lid 10 with the hydraulic filter assembly, put coffee or other brewing granules into the bottom of the cup body 1, pour in an appropriate amount of water, seal the filter assembly 4 into the inside of the cup body 1 until the inner lid 10 is partially press-fitted into the opening of the cup body 1, keep the lid 7 and the base 6 closed, and hold the lid 7 and the base 6 to pull up and down, driving the filter assembly 4 to rise and fall to filter. After pulling up and down a certain number of times, open the lid 7 and drink directly from the spout 5.
