Problems solved by technology

[0003] 1. The heating and pressurizing components are scattered and fixed in the inner cavity of the machine shell. When brewing coffee, there are potential safety hazards in the connection and sealing reliability of the internal waterway, and it is not easy to assemble and test the product.
[0004] 2. The raw material seat is directly connected to the lower edge of the fuselage shell through thread sealing, which not only causes the fuselage shell to bear a lot of pressure during the process of brewing coffee under high pressure (usually the espresso brewing pressure is about 15 atmospheres). Cracked and damaged, and after brewing coffee, if there is some residual pressure on the raw material seat, the raw material seat connected to the lower end of the fuselage is difficult to unscrew, remove and clean
[0005] 3. The puncture needle used to puncture the capsule coffee is exposed, not only is it easy to be punctured when cleaning after use, but also for coffee capsules of different specifications, in order to achieve the best brewing, some puncture needles have different positions or shapes (such as used for The needle for brewing Nespresso coffee capsules has 3 claws), so when the raw material seat is screwed and installed at the lower end of the fuselage after the coffee capsule is put in and rotated, the rotating needle will destroy the top shell of the coffee capsule, resulting in the coffee in the capsule Phenomenon of powder leakage

Embodiment 1

[0044] Such as Figure 6 , Figure 7 As shown, the brewing assembly (Dolce Gusto) is independently arranged under the coffee machine body, and is mainly composed of a raw material cover 15 and a first raw material seat 14 . Wherein the outer edge of the upper end of the raw material cover is provided with a protrusion 47, which is connected with the second slot 43 of the sealing disc at the lower end of the coffee machine body when brewing coffee. The center of the raw material cover is provided with a penetrating water guide hole 46, which is upwardly connected to the second outlet pipe 37 of the sealing plate. The inner cavity of the water guide hole 46 is provided with a step, and the fourth sealing ring 19 is arranged on the step and is connected to the sealing ring inserted into the raw material cover. The second water outlet pipe 37 of the disc is closely matched and sealed.

[0045] Such as Figure 8 , Figure 9 , Figure 10 As shown, the raw material cover is prov...

Embodiment 2

[0049] Such as Figure 11 As shown, the brewing assembly (Nespresso) is mainly composed of the raw material cover 15 and the second raw material seat 52 . Wherein the raw material cover is provided with a capsule adapter 55 for placing Nespresso coffee capsules, and the corresponding position of the capsule adapter 55 and the raw material cover mounting hole 51 is also provided with a mounting hole, and is fixedly connected with the raw material cover 15 by screws. The raised water guide pipe has the same structure and size as the water guide pipe 48 of the water inlet tray 17 in the DolceGusto brewing assembly. There are four third card slots 50 inside the water guide tube. Below the third card slot 50 is a The second step, the second step is provided with a spring, the spring is provided with a three-claw needle 58 for piercing the Nespresso coffee capsule, and the upper end of the three-claw needle 58 is provided with 4 protrusions to match the third card slot 50, and the n...

Abstract

The invention discloses a portable coffee maker which comprises a coffee maker body and a coffee brewing assembly, wherein the coffee maker body comprises a cup cover, a shell, a heating assembly anda pressurization control assembly; the shell is provided with the cup cover, and is internally provided with the heating assembly and the pressurization control assembly, the heating assembly is connected with the pressurization control assembly, the pressurization control assembly is connected with the coffee brewing assembly, and the coffee brewing assembly is arranged below the coffee maker body and is detachably connected with the coffee maker body. The portable coffee maker which is safe, reliable and suitable for different specifications is manufactured by adopting the technical scheme.The heating assembly and the pressurization control assembly are reliably connected together in a sealing manner, and the potential safety hazard is eliminated. The coffee brewing assembly taken as anindependent assembly is detachably connected with the coffee maker body, so that the cleaning is convenient, and the coffee brewing assemblies with different specifications can be changed to brew coffee capsule or ground coffee.

Description

technical field [0001] The invention relates to the field of coffee machines, in particular to a portable coffee machine. Background technique [0002] With the popularity of coffee machines, portable coffee machines are becoming more and more popular in the market because of their affordable price, small size and portability. But there are various portable coffee machines on the market in recent years, but there are still the following disadvantages: [0003] 1. The heating and pressurizing components are scattered and fixed in the inner cavity of the machine shell. When brewing coffee, there are potential safety hazards in the connection and sealing reliability of the internal waterway, and it is not easy to assemble and test the product. [0004] 2. The raw material seat is directly connected to the lower edge of the fuselage shell through thread sealing, which not only causes the fuselage shell to bear a lot of pressure during the process of brewing coffee under high pr...
