Description

Technical Field

[0001] This utility model relates to the technical field of beverage brewing devices, and in particular to a liftable tea basket assembly and brewing device. Background Technology

[0002] To facilitate drinking, beverage brewing devices typically include a separate tea basket from the kettle body. This basket holds tea leaves, herbs, etc., preventing contamination of the brewing liquid. To facilitate separation of the tea basket from the liquid in the kettle, existing brewing devices often feature a tea basket with a lifting function. Generally, a hole is made in the center of the lid, through which a lifting shaft connects to the tea basket. A magnet is located at the top of the tea basket, and another magnet is located at the bottom of the lid. This magnetic connection allows the tea basket to easily detach from the lid for downward movement to brew tea, or to move upward and engage with the lid to separate the tea basket from the liquid in the kettle. However, in this structure, because the magnets are located at the bottom of the lid and the top of the tea basket, the top of the tea basket and the bottom of the lid collide directly when the basket is raised to the top, producing a rattling sound and affecting the user experience. Some lifting mechanisms use mechanical locking points or spring clips, where the lifting rod rubs directly against these points or clips during movement, also producing a rattling sound and affecting the user experience. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a liftable tea basket assembly and brewing device that reduces the collision between the tea basket and the lid when they are closed or the mechanical friction during the movement of the lifting rod.

[0004] According to a first aspect of the present invention, a liftable tea basket assembly includes: a cover, a lifting shaft, and a tea basket. The lifting shaft passes through the cover, has a lifting knob at its top, and is connected to the tea basket at its bottom. A first magnetic attractor is housed inside the lifting shaft near its bottom, and a second magnetic attractor is housed inside the cover near the lifting shaft. When the lifting shaft rises, the tea basket is separated from the beverage, and the first magnetic attractor and the second magnetic attractor can be attracted together radially.

[0005] According to a second aspect of the present invention, a brewing device is applied to the above-mentioned liftable tea basket assembly, including a pot body, the lid for sealing the opening of the pot body, and the tea basket located inside the pot body.

[0006] The liftable tea basket assembly and brewing device according to the embodiments of the present utility model have at least the following beneficial effects: the lifting shaft drives the tea basket to move up and down. When the lifting shaft rises to the maximum height and separates the tea basket from the beverage, the second magnetic suction member located inside the lid and the first magnetic suction member located inside the lifting shaft are on the same horizontal plane. The two will generate radial magnetic attraction force, causing the lifting shaft to be attracted to the lid, thereby suspending the tea basket below the lid. There will be no collision between the tea basket and the lid, and mechanical friction during the movement of the lifting rod can also be avoided, thus improving the user experience.

[0007] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0020] Reference Figure 1 and Figure 8 This utility model discloses a height-adjustable tea basket assembly, comprising: a cover, a lifting shaft 10, and a tea basket. The lifting shaft 10 passes through the cover, and a lifting knob 12 is provided at the top of the lifting shaft 10. The bottom end of the lifting shaft 10 is connected to the tea basket. A first magnetic suction member 101 is housed inside the lifting shaft 10 near its bottom end, and a second magnetic suction member 102 is housed inside the cover near the lifting shaft 10. When the lifting shaft 10 rises, the tea basket is separated from the beverage, and the first magnetic suction member 101 and the second magnetic suction member 102 can be attracted radially. The lifting shaft 10 drives the tea basket to move up and down. When the lifting shaft 10 rises to its maximum height and separates the tea basket from the beverage, the second magnetic suction member 102 located inside the lid and the first magnetic suction member 101 located inside the lifting shaft 10 are on the same horizontal plane. The two will generate radial magnetic attraction, causing the lifting shaft 10 to be attracted to the lid, thereby suspending the tea basket below the lid. This prevents the tea basket from colliding with the lid and avoids mechanical friction from the locking points or springs during the movement of the lifting rod, thus improving the user experience.

[0021] like Figure 2 In some embodiments, both the lifting shaft 10 and the cover are made of stainless steel. The lifting shaft 10 is hollow inside, and a limiting member 11 is provided inside the lifting shaft 10. The first magnetic suction member 101 is located below the limiting member 11, and a sealing plug 13 is provided at the bottom end of the lifting shaft 10 to prevent beverages from entering the lifting shaft 10. The structure is simple and saves materials. Stainless steel has good rust resistance and is suitable for beverage brewing devices.

[0022] In some embodiments, the lifting shaft 10 has a first receiving cavity near its bottom end, and the first magnetic suction member 101 is disposed in the first receiving cavity.

[0023] like Figure 3 and Figure 4 In some embodiments, a sealing member 14 is welded / bonded to the bottom end of the lifting shaft 10. Preferably, the sealing member 14 can be a screw / nut post, with the tail of the screw / nut inserted into the lifting shaft 10, the head of the screw / nut post used to seal the bottom end of the lifting shaft, and the head of the screw / nut post can be welded to the connecting cover 42 of the tea basket.

[0024] like Figure 3 , Figure 5 As shown, in some embodiments, the cover includes an upper cover 21 and a lower cover 22. The upper cover 21 is connected to the lower cover 22, and a second accommodating cavity 20 is formed between the upper cover 21 and the lower cover 22. The upper cover 21 and the lower cover 22 are respectively provided with opposing through holes. The lifting shaft 10 passes through the upper cover 21, the second accommodating cavity 20 and the lower cover 22 in sequence through the through holes. The annular magnetic suction member is disposed in the second accommodating cavity 20.

[0025] like Figure 3 In some embodiments, the upper cover 21 and the lower cover 22 are detachably connected by a snap-fit ​​structure 200, facilitating assembly and maintenance. The upper cover 21 and the lower cover 22 can also be ultrasonically welded or bonded.

[0026] like Figure 5 , Figure 6 In some embodiments, the second magnetic chuck 102 is an annular magnetic chuck, which surrounds the lifting shaft 10 and is disposed inside the cover. At least one of the first and second magnetic chucks is a magnet, and the corresponding other is a magnetic material that can be attracted by a magnet, or both are magnets. Preferably, the first magnetic chuck 101 is made of a magnetic material, and the second magnetic chuck 102 is a magnet. Since the second magnetic chuck 102 is an annular magnetic chuck, the magnetic force between the second magnetic chuck 102 and the first magnetic chuck 101 is sufficient to attract the lifting shaft 10 and the tea basket. Using iron for the first magnetic chuck 101 saves costs. In some embodiments, both the first magnetic chuck 101 and the second magnetic chuck 102 are magnets, resulting in a stronger magnetic force, suitable for large-capacity brewing devices. In some embodiments, the first magnetic chuck 101 is a magnet, and the second magnetic chuck 102 is made of a magnetic material, suitable for devices with small brewing capacities.

[0027] Furthermore, it also includes a ring-shaped encapsulation structure, in which the ring-shaped magnetic component is disposed to avoid contact with the lifting shaft 10 and the beverage, thereby preventing impact on beverage quality and corrosion of the magnetic component by the beverage. Figure 5The annular encapsulation structure includes an annular bottom shell 31 and an annular sealing member 32 for sealing the opening of the annular bottom shell 31. The annular magnetic attractor is disposed in the annular bottom shell 31. In some embodiments, the outer surface of the annular magnetic attractor is entirely sealed with adhesive, which can also achieve a sealing effect, eliminating the need for an annular encapsulation structure and saving costs.

[0028] Furthermore, the second accommodating cavity 20 is also provided with a sealing element 30. The sealing element 30 is arranged around the lifting shaft 10 and abuts against the lifting shaft 10. The sealing element 30 is used to prevent the beverage in the pot from seeping upward along the gap between the lifting shaft and the hole. The sealing element 30 can be positioned above or below the annular magnetic suction element.

[0029] Furthermore, the tea basket includes a basket 41 and a connecting cover 42, the connecting cover 42 being connected to the lifting shaft 10, and the basket 41 and the connecting cover 42 being detachably connected by a snap-fit ​​structure 300 (the specific structure of the snap-fit ​​structure 300 is as follows). Figure 4 , Figure 7 , Figure 8 (As shown), this makes it easy to remove the basket 41 to place tea leaves in the basket 41 or to clean the basket 41.

[0030] like Figure 7 In some embodiments, the top of the connecting cover 42 protrudes upward to form a protrusion 40, and the lifting shaft 10 is sleeved on the protrusion 40. The lifting shaft 10 can be welded to the connecting cover 42 by welding.

[0031] like Figure 8 In some embodiments, a small cover plate 44 is provided on the back of the connecting cover 42, and a third magnetic attractor 43 is provided between the small cover plate 44 and the connecting cover 42. The third magnetic attractor 43 and the first magnetic attractor 101 are axially attracted to each other, so that the lifting shaft 10 and the connecting cover 42 are detachably connected. Further, a groove 45 is provided on the top of the connecting cover 42, and a flat plate 15 is welded to the bottom end of the lifting shaft 10. The flat plate 15 is engaged with the groove 45 and abuts against the bottom of the groove 45. The small cover plate 44 serves to seal the third magnetic attractor 43, and the flat plate 15 increases the contact area. After attraction, the flat plate 15 and the groove 45 fit more stably, making the attraction between the lifting shaft 10 and the connecting cover 42 more secure.

[0032] This application also discloses a brewing device, including the aforementioned liftable tea basket assembly, and a kettle body, wherein the lid is used to seal the opening of the kettle body, and the tea basket is located inside the kettle body. Figure 3 , Figure 6As shown, a bottom shell 23 is provided below the lower cover 22, and a rubber ring 24 is fitted on the upper part of the bottom shell 23. The bottom shell 23 has an opening for the lifting shaft 10 to pass through. The edge of the bottom shell 23 is engaged with the edge of the lower cover 22. The rubber ring 24 is used to engage or seal the opening of the pot body.

[0033] It will be readily understood by those skilled in the art that the above preferred methods can be freely combined and superimposed without conflict.

[0034] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
