Lock catch structure of brewage unit of coffee machine

Abstract

The invention discloses a lock catch structure of a brewage unit of a coffee machine. The lock catch structure comprises a poking piece (1), a universal driving shaft (2), a swing arm (3) and a locking bolt (18), and a first torsion spring (12) generates downward trend toward the locking bolt (18) through the universal driving shaft (2) and the swing arm (3); the locking bolt (18) has two states, namely an unlocking state and a locking state; when the locking bolt (18) is in the unlocking state, the outer end of a lock tongue (13) abuts against a wedge-shaped ejecting block (25) of the locking bolt (18) under the action of a second torsion spring (14), and the inner end of the lock tongue (13) is not in contact with a brewage device (17); when the locking bolt (18) is in the locking state and the brewage device (17) is located at a non-initial tilt angle, the inner end of the lock tongue (13) is not in contact with the brewage device (17), and the outer end of the lock tongue (13) is inserted into a lockhole (16) of the locking bolt (18) under the action of the second torsion spring (14). By means of the lock catch structure, when the brewage unit is assembled, an axle key between a driven shaft (26) and a driving shaft can be aligned accurately.

Description

technical field [0001] The invention relates to a component of a coffee machine, in particular to a locking structure of a brewing unit of a coffee machine. Background technique [0002] The coffee machine includes a housing and a brewing unit. The housing is provided with an inner cavity for accommodating the brewing unit. The opening of the inner cavity is located on the side of the housing, and a driving shaft protrudes from the inner surface of the inner cavity. The brewing unit includes a bracket and a brewer. There is a brewing cavity with an upward opening in the brewer. The brewer is fixed with a driven shaft. The two support plates on both sides of the bracket are respectively provided with a shaft hole. The driven shaft can be rotatably fitted in the In the two shaft holes of the two support plates. When the brewing unit is pushed into the inner cavity of the housing, the driving shaft and the driven shaft are fitted together and the two are limited in the circumf...

AI Technical Summary

Problems solved by technology

[0007] The locking structure of the brewing unit of the coffee machine in the prior art has the following defects: People often need to remove the brewing unit from the coffee machine housing for cleaning. From the above dynamic process, it can be known that when the brewing unit is separated from the coffee machine housing, the brewing The swing angle of the brewer is random, that is to say, the brewer can be separated from the shell at any angle. , because the swing angle of the brewer has changed, that is, the swing angle of the driven shaft has changed, while the swing angle of the driving shaft on the housing has not changed, which makes the shaft key between the driving shaft and the driven shaft mismatched and mismatched, It cannot be assembled. In actual operation, people often cannot find the specific swing angle of the brewer when it is disassembled. Only by constantly trying various swing angles of the brewer can the shaft key between the driving shaft and the driven shaft match. The assembly process very troublesome
