Embodiment 1

[0034] like Figure 1 to Figure 6 The brewing unit of the coffee machine shown includes a first side wall 1 and a second side wall 2, and the two side walls are opposite to each other to enclose a space for placing a brewing head 7 and a coffee pocket 5, wherein the brewing head 7 is a space for placing a brewing head 7 and a coffee pocket 5. The movable part is placed in the upper part of the space, the coffee pocket 5 is placed under the brewing head 7, and is fixed between the two side walls by the rotating shaft. The brewing head 7 and the coffee pocket 5 together form a brewing cavity. The brewing unit also includes A driving device used to drive the brewing head 7 to move up and down while driving the coffee pocket 5 to rotate.

[0035] The driving device can either be arranged on the first side wall 1 or the second side wall 2 , or can be arranged on the first side wall 1 and the second side wall 2 at the same time. In this embodiment, the driving device is provided on...

Embodiment 2

[0044] like Figure 7 to Figure 11 As shown, this embodiment adds a discharge mechanism on the basis of Embodiment 1. The discharge mechanism is mainly aimed at coffee machines using coffee capsules. The other structures of this embodiment are the same as Embodiment 1 and will not be repeated here. describe.

[0045] like Figure 10 As shown, the coffee capsule 50 used in this embodiment is a jelly-like structure, including a capsule body 52 and a cover body 53 sealed on the opening of the capsule body 52. ​​The opening of the capsule body 52 is provided with a radially outward flange, Namely collar 54.

[0046] The unloading mechanism described in this embodiment includes unloading arms 71 located on both sides of the brewing head 7 and a resetting mechanism for the unloading arms. Above, one end of the unloading arm 71 extends under the brewing head 7, and the other end extends out of the brewing unit. When the brewing chamber is in a closed state, the unloading arm 71 ca...

Embodiment 3

[0051] like Figures 12 to 14 As shown, this embodiment adds an unloading mechanism on the basis of the first embodiment, and the unloading mechanism is mainly aimed at coffee machines using coffee cakes.

[0052] In this embodiment, three uprights 77 extend downwards from the lower end of the brewing head 7, and each upright 77 is provided with a stopper 76. Correspondingly, the coffee pocket 5 is provided with three grooves corresponding to the uprights 77. When the brewing chamber is in a sealed state, the column 77 is just inserted into the groove of the coffee pocket. Of course, the number of columns 77 and grooves is not limited to 3, and more than 2 columns 77 can meet the requirements of the present invention.

[0053] The unloading mechanism shown in this embodiment includes: a pair of ejectors 75, a part of each ejector 75 can extend into the brewing chamber; an unloading arm 71, one end of the unloading arm 71 touches the ejector rod 75, the other end stretches ou...

Abstract

The invention provides a brewing unit of a coffee maker. The brewing unit comprises a first side wall and a second side wall opposite to the first side wall. A coffee pocket and a brewing head are arranged in space enclosed by the first side wall and the second side wall, the coffee pocket is used for accommodating coffee capsules or coffee cakes, the brewing head is used for squeezing the coffee capsules or coffee cakes, driving devices which are used for driving the brewing head to linearly move and simultaneously driving the coffee pocket to rotate are arranged on the first side wall and / or the second side wall, each driving device comprises a first gear, a second gear, a first driving arm, a second driving arm, a slide guide groove, a shifting shaft and a coffee pocket shifting rod, each first gear is meshed with the corresponding second gear, each first driving arm is connected with the brewing head and the corresponding first gear, each second driving arm is connected with the brewing head and the corresponding second gear, each slide guide groove is used for limiting the brewing head when the brewing head moves linearly, each shift shaft is arranged on the corresponding first gear or the corresponding second gear, and each coffee pocket shifting rod is coaxially connected with the coffee pocket and can accommodate the corresponding shifting shaft. The brewing unit has the advantages that the coffee capsules or coffee cakes can be placed in the coffee pocket conveniently, the brewing unit is simple in operation, and dead points cannot be formed easily.

Description

technical field [0001] The invention relates to a coffee brewing locking mechanism, which belongs to an improved technology for locking the brewing system of a coffee machine. Background technique [0002] The coffee machines on the market generally include the following parts: a water tank, a heating device, and a brewing unit. The brewing unit is the core component of a coffee machine. The so-called brewing unit is generally composed of a brewing head, a coffee pocket and a driving device. The brewing head The heating device of the coffee machine is communicated with the water tank. The coffee pocket is used for placing coffee capsules or coffee cakes. The brewing head of most brewing units on the market is a fixed structure. The coffee pocket can move up and down under the driving of the driving device. When the coffee pocket is far away When the brewing head is in operation, the brewing cavity enclosed by the coffee pocket and the brewing head is in an open state; when t...
