Detailed Description

The invention will be further explained with reference to the drawings.

As shown in FIG. 1, the coffee maker according to the embodiment of the present invention includes a brew chamber 10, a brew head 11, and a drive mechanism for driving the brew head 11 towards and away from the brew chamber 10.

As shown in fig. 2 and 3, the brew head 11 includes a base 12 and a filter lid 13 disposed on the base 12. The base 12 includes a middle plate 121 and two side plates 122 extending from the same side of the middle plate 121. The filter cover 13 is provided on the middle plate 121 and on the same side of the middle plate 121 as the side plate 122. The brew head 11 also includes an automatic capsule dropping mechanism. The automatic capsule dropping mechanism comprises a sliding block 14 capable of supporting the capsule before brewing coffee and blocking the capsule after brewing coffee so that the capsule disengages from the brewing head 11 and drops into the drip pan.

In this embodiment, the two side plates 122 are provided with guide holes 15 respectively on opposite sides thereof for receiving the sliding blocks 14. The guide hole 15 can restrict the moving direction of the slide block 14 so that the slide block 14 can move in a direction perpendicular to the axis of the filter cover 13. The hole wall of the guide hole 15 is provided with a protrusion 151 extending along the axial direction of the guide hole 15, and the sliding block 14 is provided with a groove 141 matched with the protrusion 151. Therefore, the sliding block 14 has high movement precision in the guide hole 15, and the stability of the movement process is ensured.

The side plate 122 is provided with a fixed cover 16 disposed opposite to the slide block 14. The automatic capsule dropping mechanism further comprises a first spring 17 arranged between the sliding block 14 and the fixed cover 16. A positioning column is arranged on one side of the sliding block 14 facing the fixed cover 16, and the first spring 17 is sleeved on the positioning column. The first spring 17 can drive the sliding block 14 to automatically reset.

The automatic capsule dropping mechanism further comprises an actuating rod 18 in driving connection with the sliding block 14. The slide block 14 is further provided with a positioning hole 142 (shown in fig. 3 and 5), and the first end 181 (shown in fig. 4) of the actuating rod 18 passes through the side plate 122 and is inserted into the positioning hole 142 toward the top 122a of the brewing base 10. The wall of the positioning hole 142 of the sliding block 14 is provided with a protrusion 143 (as shown in fig. 5 and 6), and the first end 181 of the actuating rod 18 is provided with a recess 183 (as shown in fig. 4) engaged with the protrusion 143. The sliding block 14 is provided with a supporting groove 144 for supporting the capsule, so that the user can conveniently place the capsule on the sliding block 14. When the protrusion 143 of the sliding block 14 is engaged with the recess 183 of the actuator bar 18, the supporting groove 144 of the sliding block 14 can hold the collar of the capsule. The automatic capsule-dropping mechanism further includes a second spring 19 disposed between the second end 182 of the actuation bar 18 (shown in fig. 4) and the top portion 122a of the side plate 122.

As shown in fig. 7, 8 and 9, when the handle 99 is in the open state, the capsule is placed in the support groove 144 of the slider block 14. The handle 99 is then depressed, as shown in figures 10, 11 and 12, and the drive mechanism actuates the brew head 11 to move in a direction towards the brew chamber 10. When the second end 182 of the actuating rod 18 of the brewing head 11 presses against the surface of the brewing base 10 facing the brewing head 11, the actuating rod 18 stops moving, the base 12 and the sliding block 14 move continuously, the concave portion 183 of the actuating rod 18 gradually separates from the convex portion 143 of the sliding block 14, and the side plate 122 starts to compress the second spring 19. As shown in fig. 11 and 12, during the gradual separation of the recess 183 of the actuator rod 18 and the protrusion 143 of the sliding block 14, the protrusion 143 of the sliding block 14 gradually moves out of the recess 183 and moves toward the outer peripheral surface of the actuator rod 18, so that the actuator rod 18 pushes the sliding block 14 to start moving in the guide hole 15. Thus, the two sliding blocks 14 move in opposite directions, the distance between the two supporting grooves 144 becomes larger and larger, and the collar of the capsule gradually comes out of the supporting grooves 144. The moving slide 14 compresses the first spring 17.

Preferably, the axis of the positioning hole 142 is parallel to the moving direction of the brew head 11 and perpendicular to the axis of the guide hole 15. Thus, the motion track of the actuating rod 18 and the motion track of the sliding block 14 are in a cross shape. The actuating rod 18 can easily move along the axial direction of the positioning hole 142 after pressing against the opposite surface of the brewing base 10, and the sliding block 14 is pushed to move along the guide hole 15 with less labor.

The brewing seat 10 comprises a housing 101 arranged opposite the filter cover 13 and intended to house the capsule. As shown in fig. 13, 14 and 15, after the handle 99 is fully closed, the recess 183 of the actuation bar 18 is fully disengaged from the protrusion 143 of the glide block 14. The projection 143 of the sliding block 14 moves onto the outer circumferential surface of the actuating rod 18, and the amount of retraction movement of the sliding block 14 in the guide hole 15 reaches a maximum, at which point the capsule is completely ejected from the support groove 144 and substantially completely enters the receiving cavity of the receiving portion 101 of the brewing holder 10. After the capsule is held by the holding part 101 and the filter cover 13, the brewing operation is started.

After the brewing operation is completed, the handle 99 is opened and the drive mechanism actuates the brewing head 11 to move away from the brewing base 10. After the movement starts, the elastic restoring force of the second spring 19 can push the actuating rod 18, so that the actuating rod 18 and the sliding block 14 move relatively, and the convex part 143 of the sliding block 14 moves towards the concave part 183 close to the actuating rod 18. When the second spring 19 is completely reset, the second end 182 of the actuating rod 18 is released from the contact with the brewing seat 10, and the sliding block 14 is reset by the elastic restoring force of the first spring 17, the protrusion 143 provided thereon moves from the outer circumferential surface of the actuating rod 18 into the recess 183 of the actuating rod 18, so that the actuating rod 18 and the sliding block 14 can no longer move relatively, and the actuating rod 18, the sliding block 14 and the base 12 move synchronously to be away from the brewing seat 10.

During the movement of the protrusion 143 of the sliding block 14 into the recess 183 of the actuating rod 18, the two sliding blocks 14 move towards each other, so that the distance between the two sliding blocks 14 becomes smaller and smaller, and the abutting surface of the sliding block 14 facing the middle plate 121 is buckled on the collar of the capsule to generate resistance to the capsule. During the distance of the brewing head 11 from the brewing seat 10, the capsule gradually comes out of the housing 101, being blocked by the sliding block 14. When the capsule is completely removed from the receptacle 101, it falls out of the brewing head 11 under its own weight and falls into a drip pan.

When the capsule coffee machine provided by the embodiment of the invention is used for brewing coffee, in the process that the brewing head 11 is close to or far away from the brewing seat 10, the sliding block 14 is controlled to reciprocate in the guide hole 15 through the actuating rod 18, so that the accommodating part 101 of the brewing seat 10 and the sliding block 14 of the brewing head 11 are not in direct contact all the time, the problem of abrasion between the accommodating part 101 and the sliding block 14 is avoided, the service lives of all components are prolonged, the capsule coffee machine provided by the embodiment of the invention can be still normally used after being used for a long time, and the satisfaction degree of users is improved.

In addition, the elastic restoring force of the second spring 19 can also provide an assisting force for the operator during the opening process of the handle 99, so that the user can operate the handle 99 more easily. Since the accommodating portion 101 of the brewing base 10 and the sliding block 14 are not in direct contact all the time, the process of pressing the handle 99 by the operator is smoother.

In one embodiment, the longitudinal cross-sectional shape of the recess 183 of the actuation bar 18 may be trapezoidal or circular. The actuation bar 18 is circular or square in cross-section.

While the invention has been described with reference to a preferred embodiment, various modifications may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In particular, the technical features mentioned in the embodiments can be combined in any way as long as there is no structural conflict. It is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include all embodiments falling within the scope of the appended claims.
