[0049] refer to Figure 8 , Figure 9 and Figure 10 , Figure 8 The locking device for the brewer provided in this embodiment of the utility model
[0050] Diagram showing the engagement state. Figure 9 The diagram shows the locking device of the brewer provided in this embodiment of the utility model in the disengaged state. Figure 10 The diagram shows the locking device of the brewer provided in this embodiment of the utility model in the locked position. Figure 8 , Figure 9 and Figure 10 As shown, the working principle is as follows: When the brewing chamber 30 is in the powder receiving position and the locking device 20 is engaged with the main body groove (not shown in the figure), the conical positioning block 2221 of the locking plate 222 is positioned in the cylindrical boss positioning groove 31 of the brewing chamber 30; under the action of the locking plate spring 24, the locking plate 222 rotates around its pivot 2223, and the locking head 2222 of the locking plate 222 rotates counterclockwise to the limit position; the locking plate 222 disengages from the clip 2211 of the T-shaped buckle plate 221, and the brewer bracket 10 is grasped by hand, and the index finger hooks the buckle head 2213 of the T-shaped buckle plate 221 and pulls it down, so that the buckle head 2213 moves downward along the rectangular guide hole 212A, thereby disengaging the clip head 2212 from the main body groove (not shown in the figure), and the brewer and related components are removed.
[0051] When the brewing chamber 30 is still in the powder receiving position and the locking device 20 is disengaged from the main body locking groove, the conical positioning block 2221 of the locking plate 222 is positioned in the cylindrical boss positioning groove 31 of the brewing chamber 30. Under the action of the locking plate spring 24, the locking plate 222 rotates around its pivot 2223. The locking head 2222 of the locking plate 222 rotates counterclockwise to the limit position, and the locking plate 222 disengages from the clip 2211 of the T-shaped buckle plate 221. The index finger that hooks the buckle head 2213 of the T-shaped buckle plate 221 is released. Under the action of the buckle spring 23, the buckle head 2213 moves upward along the rectangular guide hole 212A, thereby locking the clip head 2212 with the main body locking groove (not shown in the figure), and the brewer and related components cannot be removed.
[0052] With the brewing chamber 30 in the brewing position and the locking device 20 in the locked position, the conical positioning block 2221 of the locking plate 222 disengages from the cylindrical boss positioning groove 31 of the brewing chamber 30. Under the action of the locking plate spring 24, the locking plate 222 rotates around its pivot 2223. The locking head 2222 of the locking plate 222 rotates clockwise to its limit position, and the locking plate 222 engages with the clip 2211 of the T-shaped buckle plate 221. Hold the brewer bracket 10 with your hand and hook your index finger onto the T-shaped buckle plate 221. Pulling the buckle 2213 downwards prevents it from moving downwards along the rectangular guide hole 212A, thus preventing the buckle 2212 from disengaging from the main body buckle groove (not shown in the figure) and making it impossible to remove the brewer components. It should be noted that when the conical positioning block 2221 abuts against the cylindrical boss positioning groove 31, the locking plate 222 will not lock the T-shaped buckle 221; when the conical positioning block 2221 does not abut against the cylindrical boss positioning groove 31, the locking plate 222 locks the T-shaped buckle 221.
