Description

Technical Field

[0001] The utility model relates to coffee machine equipment, in particular to a locking mechanism of a coffee machine and the coffee machine. Background Art

[0002] Household coffee machines typically use a drain plate to introduce water into the funnel, which is fitted with a locking bracket. Currently, most locking brackets are manually locked using a lever lock, creating a water cavity between the bracket and the drain plate. This structure is cumbersome to operate and lacks intelligence. A small number of systems utilize a motor to rotate a drive gear, which in turn rotates a lifting gear body, which in turn drives a lifting connecting rod. The lifting connecting rod, via a connecting rod, drives the tamping head to press against or away from the funnel. For example, an automatic tamping device and coffee machine with publication number CN220824157U is available. Utility Model Content

[0034] The following is combined with Figure 1-4 The utility model is further described in detail with examples.

[0035] Example 1

[0036] The coffee machine's locking mechanism includes a base 1 and a motor 2 mounted above the base 1. A drain plate 3 is mounted on the base 1. The drain plate 3 has a number of holes through which water can be evenly dispersed into a funnel 9. A vertically movable locking bracket 4 is mounted above the drain plate 3. The motor 2 is connected to the locking bracket 4 and drives it up and down. The locking bracket 4 is locked to the base 1 and forms a water chamber 100 with the drain plate 3. Water accumulates in the water chamber 100 and then flows out through the drain plate 3.

[0037] A screw 5 is mounted on the output end of the motor 2. A cavity 41 is provided on the locking bracket 4. A fixing plate 6 is fastened to the locking bracket 4, covering the cavity 41. The fixing plate 6 has a threaded hole. The end of the screw 5 extends through the threaded hole into the cavity 41 and is threadedly connected to the fixing plate 6. When the motor 2 drives the screw 5 to rotate, the fixing plate 6 rises and falls along the threaded section of the screw 5. When the fixing plate 6 rises and falls, it also drives the locking bracket 4 to rise and fall, thereby electrically locking the locking bracket 4 to the base 1. This locking mechanism has a simple structure, with few intermediate components between the motor 2 and the locking bracket 4. Power can be transmitted to the locking bracket 4 in a timely manner, and the locking bracket 4 has a fast response time.

[0038] The base 1 is provided with at least two guide posts 7 pointing vertically upward. In this embodiment, there are three guide posts 7. The guide posts 7 are integrally formed on the base 1. The locking bracket 4 is mounted on the guide posts 7 and can be raised and lowered along the guide posts. When the locking bracket 4 is raised and lowered on the base 1 through the guide posts 7, the lifting stability is high, and the locking bracket 4 can be accurately locked on the base 1.

[0039] The locking mechanism also includes a motor bracket 8, which is equipped with a number of positioning tubes 81 corresponding to the number of guide posts 7. The positioning tubes 81 are integrally formed with the motor bracket 8 and fastened to the tops of the guide posts 7 with screws. The locking bracket 4 is positioned between the motor bracket 8 and the base 1. The motor bracket 8 is used to mount the motor 1 and to limit the height at which the locking bracket 4 can be raised.

[0040] The rear end of the locking bracket 4 is provided with a water inlet connector 42 for connecting to the water pipe. The interface of the water inlet connector 42 is arranged horizontally and faces rearward. The water inlet connector 42 is connected to the water cavity 100. The water pipe can be inserted into the water inlet connector 42 horizontally. The layout is reasonable. The water inlet connector 42 is not arranged vertically to avoid interference between the water pipe and the motor bracket 8.

[0041] A blade 10 for piercing capsules is fixed to the lower end of the drain plate 3. The motor 2 drives the locking bracket 4 up and down, which in turn drives the drain plate 3 up and down synchronously. The drain plate 3 is sealed to the locking bracket 4 via a sealing gasket 20, which is made of silicone. The drain plate 3 descends onto the funnel 9 and is sealed therewith. When capsules are placed in the funnel 9, the blade 10 pierces the capsules during the drain plate 3's descent, facilitating subsequent brewing.

[0042] The locking mechanism also includes a funnel 9, in which a coffee powder bin, a small capsule bin, a tea capsule bin or a large capsule bin can be placed. A mounting groove 11 for mounting the funnel 9 is provided at the lower end of the base 1. Both side walls of the mounting groove 11 are provided with slide grooves 12. The slide grooves 12 are used to support the funnel 9. Support blocks 91 are provided on both side walls of the funnel 9. The support blocks 91 are convex blocks and are integrally formed at the cup mouth of the funnel 9. The support blocks 91 slide into the slide grooves 12 and mount the funnel 9 on the base 1.

[0043] Example 2

[0044] The features of Example 2 are basically the same as those of Example 1, except that the fixing plate 6 is fastened to the locking bracket 4 by screws. The fixing plate 6 is a metal plate. The fixing plate 6 made of metal has high strength. When the screw rod 5 and the fixing plate 6 move in coordination, the connection strength between the two is high and the thread is not easily damaged.
