Technical Field

[0001] This utility model relates to the field of coffee maker technology, and in particular to a steam coffee maker. Background Technology

[0002] In existing technology, steam coffee makers such as Moka pots mostly use screws or snap-fit ​​connections between the upper and lower bodies. Among them, screw connections are cumbersome to operate, while snap-fit ​​connections have safety hazards such as insufficient locking force and easy leakage under high pressure.

[0003] Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a steam coffee maker that is not only easy to assemble and disassemble, and has a reliable seal, but also has the advantages of low cost.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A steam coffee maker includes a lower body, an upper body, and a handle on the upper body; it also includes a pressing mechanism for detachably connecting the lower body and the upper body, the pressing mechanism including a concave base fixedly fitted to the lower end of the upper body, an annular sleeve fixedly connected to the mouth of the lower body, a stepped annular sleeve with a stepped shape that is smaller at the top and larger at the bottom and its upper and lower ends respectively fitted onto the concave base and the annular sleeve, an upper sealing ring between the upper end of the stepped annular sleeve and the concave base, a lower sealing ring fitted inside the lower end of the stepped annular sleeve and whose lower surface abuts against the annular sleeve, and a coffee filter with its upper edge embedded in the lower sealing ring for holding coffee powder, fitted onto the stepped annular sleeve. The device includes a closable clamp at the lower end and a knob assembly on the handle; the concave base has a first air inlet, and the bottom wall of the coffee filter has a second air inlet, which together form a steam passage from the lower body to the upper body; the inner edge of the upper end of the clamp abuts against the stepped surface of the stepped ring, and the inner edge of the lower end of the clamp stops against the ring; the upper surface and lower periphery of the upper sealing ring abut against the inner periphery of the upper end of the stepped ring and the periphery of the coffee filter, respectively; the knob assembly includes a knob and a pressure block driven by the knob, which is used to press the free end of the clamp to complete the locking.

[0007] Furthermore, the knob assembly also includes a groove located on the outside of the handle for accommodating the knob, two sliding pillars extending inward from the inside of the knob, and two first arc-shaped sliding grooves symmetrically arranged on the bottom wall of the groove. The two sliding pillars pass through the corresponding first arc-shaped sliding grooves and are slidably connected to them. The extended ends of the two sliding pillars are fixedly connected to a rotating plate. The rotating plate is provided with two second arc-shaped sliding grooves that are mirror-staggered. The pressure block includes a first pressure block and a second pressure block. The first pressure block and the second pressure block are slidably connected to the corresponding second arc-shaped sliding grooves by sliding pins.

[0008] Furthermore, both the first and second pressing blocks have a vertical plate and a horizontal plate connected to the lower end of the vertical plate and extending inward. The upper end of the vertical plate is slidably connected to the corresponding second arc-shaped groove by a sliding pin.

[0009] Furthermore, the clamp includes a first snap-fit ​​component and a second snap-fit ​​component, both of which are semi-circular arc shapes. One end of the first snap-fit ​​component and one end of the second snap-fit ​​component are hinged to each other via a hinge shaft. The other ends of the first snap-fit ​​component and the other ends of the second snap-fit ​​component are free ends that can be separated from each other. The horizontal plates of the first pressure block and the second pressure block are respectively pressed onto the upper part of the free ends of the first snap-fit ​​component and the second snap-fit ​​component.

[0010] Furthermore, the concave chassis is an integrally bent sheet metal structural component, having a first horizontal ring, a first connecting cylinder that bends downward from the outer edge of the first horizontal ring and is used to fix it inside the lower end of the upper pot body, a second connecting cylinder that bends downward from the inner edge of the first horizontal ring, and a second horizontal ring that bends inward from the lower end of the second connecting cylinder.

[0011] Furthermore, the annular sleeve is an integrally bent sheet metal structural component, having a third horizontal ring fixed to the spout of the lower pot body, a third connecting cylinder extending upward from the inner edge of the third horizontal ring, a fourth horizontal ring extending outward from the upper end of the third connecting cylinder, and a fourth connecting cylinder extending downward from the outer edge of the fourth horizontal ring; the inner periphery of the lower end of the clamp is located below the fourth connecting cylinder, and the inner diameter of the inner periphery of the lower end of the clamp is smaller than the inner diameter of the fourth connecting cylinder, thereby forming a stop fit.

[0012] Furthermore, the coffee filter is a hollow cavity with its opening facing upwards, and a lower filter disc is fitted inside the cavity. The upper sealing ring has a concave upper filter disc embedded at its lower end, located below the concave base.

[0013] Furthermore, the handle of the kettle is provided with an upwardly extending grip.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, easy assembly and disassembly: Users simply need to rotate the knob to convert the rotational motion into clamping force. The clamp, in conjunction with the stepped ring and the ring sleeve, connects the upper and lower pot bodies. For disassembly, simply rotate the knob in the opposite direction to release the pressure block from the free end of the clamp, then pry open the clamp to remove the upper and lower pot bodies. This process is effortless and quick, completely avoiding the drawbacks of traditional screw connections requiring multiple rotations and snap-fit ​​connections requiring forceful prying, significantly improving the ease of assembling and disassembling the coffee maker.

[0016] Secondly, reliable sealing: This utility model adopts a design in which the upper surface and lower periphery of the upper sealing ring abut against the inner periphery of the upper end of the stepped ring sleeve and the upper periphery of the coffee filter, respectively. Combined with the abutment and cooperation between the lower sealing ring and the ring sleeve, when the kettle body generates steam pressure during operation, it will drive the upper sealing ring and the lower sealing ring to be further compressed in the axial direction, thereby forming a self-tightening sealing structure with better sealing effect as the pressure increases.

The inner ring of the second horizontal ring 415 is the first air inlet 411.

[0033] As described above, the annular sleeve 42 is an integrally bent sheet metal structural component, comprising a third horizontal ring 421 fixed to the spout of the lower pot body 1, a third connecting cylinder 422 extending upward from the inner edge of the third horizontal ring 421, a fourth horizontal ring 423 extending outward from the upper end of the third connecting cylinder 422, and a fourth connecting cylinder 424 extending downward from the outer edge of the fourth horizontal ring 423; the inner periphery of the lower end of the clamp 47 is located below the fourth connecting cylinder 424, and the inner diameter of the lower end of the clamp 47 is smaller than the inner diameter of the fourth connecting cylinder 424, thereby forming a stop fit. Both the concave base 41 and the annular sleeve 42 of this utility model are integrally bent sheet metal components, which significantly reduces material and manufacturing costs while ensuring structural strength and rigidity, making them suitable for mass production.

[0034] As described above, the coffee filter 46 is a hollow cavity with its opening facing upwards. The lower filter plate 6 is fitted inside the cavity, and the upper sealing ring 44 has an upper filter plate 7 that is concave and located below the concave base plate 41 at its lower end.

[0035] As described above, the handle 3 is provided with an upwardly extending grip 31.

[0036] The disassembly and assembly steps for the upper and lower kettle bodies 2 and 1 are as follows:

[0037] When disassembling, ensure that the coffee pot has cooled down. Rotate the knob 51 until the pressure block 52 disengages from the free end of the clamp 47. Then, pry open the free ends of the first locking piece 471 and the second locking piece 472 to disengage them from the stop of the annular sleeve 42. Lift the upper pot body 2 to disassemble the upper and lower pot bodies 2 and 1.

[0038] During installation, first align the lower end of the stepped ring 43 of the upper pot body 2 with the ring 42 of the lower pot body 1, then fit the clamp 47 onto the lower end of the stepped ring 43, with the inner edge of the clamp 47 abutting against the stepped surface of the stepped ring 43. Finally, reverse the knob 51 until the pressure block 52 presses against the free end of the clamp 47, thus completing the installation of the upper and lower pot bodies 2 and 1.

[0039] The above description is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Any simple equivalent changes and modifications made in accordance with the scope of the present utility model patent application and the description of the utility model shall still fall within the scope of the present utility model patent.
