The embodiment of the invention provides a residue pushing mechanism, which is applied to a brewing system of a coffee machine, in particular to a brewing system of a full-automatic coffee machine. The brewing system of the coffee machine comprises a machine body 600, a screw rod assembly 300 and a brewing chamber assembly 500, wherein the screw rod assembly 300 and the brewing chamber assembly 500 are arranged in an inner cavity of the machine body 600, and the brewing chamber assembly 500 moves linearly in the inner cavity under the action of the screw rod assembly 300. The residue pushing mechanism is arranged on the machine body 600 and used for pushing the residue cake 700 in the inner cavity to smoothly fall after the coffee brewing is finished, so that the smooth residue discharging of the brewing system of the coffee machine is realized.

For convenience of the following description, an end of the body 600 provided with the brew head assembly 100 is defined as a front end, an end of the body 600 provided with the lead screw assembly 300 is defined as a rear end, the lead screw assembly 300 is defined as an advance when moving toward the brew head assembly 100, and the lead screw assembly 300 is defined as a retreat when moving away from the brew head assembly 100. And the direction in which the screw assembly 300 moves toward the brew head assembly 100 is a first direction, and the direction in which the screw assembly 300 moves away from the brew head assembly 100 is a second direction.

As shown in fig. 1 to 13, the slag pushing mechanism of the embodiment of the present invention includes a base 210, a slag pushing assembly 220, a pushing member 230, and a limiting assembly 240. The base 210 is secured to the body 600 of the brewing system of the coffee maker. The body 600 may include an upper plate 610, a lower plate 630, and a main support 640 provided between the upper plate 610 and the lower plate 630, see fig. 1.

The slag pushing assembly 220 is rotatably disposed on the base 210 and has a slag to be pushed outside the inner cavity of the machine body 600 and a slag pushing state in the inner cavity of the machine body 600. That is, the residue pushing assembly 220 can rotate into the inner cavity or rotate away from the inner cavity to switch between the state of residue to be pushed and the state of residue pushing, so as to avoid interference of the residue pushing assembly 220 in the inner cavity to the brewing chamber assembly 500 during the coffee brewing process, and to push the residue cake 700 out of the inner cavity by the rotating force of the residue pushing assembly 220 during the residue discharging process, thereby realizing smooth residue discharging.

The pushing component 230 is disposed on the screw assembly 300 of the brewing system of the coffee maker, and is configured to push the residue pushing assembly 220 to rotate when moving along with the screw assembly 300 along the first direction, so that the residue pushing assembly 220 is switched from a residue pushing state to a residue to be pushed state. That is, when no external force is applied, the residue pushing assembly 220 is located in the inner cavity of the brewing system of the coffee maker and is kept in the residue pushing state, and when the screw rod assembly 300 moves towards the brew head assembly 100 under the driving of the driving device 400, the pushing member 230 is driven to move together, so that the pushing member 230 acts on the residue pushing assembly 220, and the residue pushing assembly 220 is switched to the outside of the inner cavity and is in the residue pushing state.

The limiting component 240 is arranged on the base 210 and can move in the moving direction of the screw rod component 300, and is used for limiting the slag pushing component 220 when the slag pushing component 220 is switched to a state of waiting to push slag, so that the slag pushing component 220 is kept in the state of waiting to push slag, and is used for removing the limitation of the slag pushing component 220 when the screw rod component 300 moves to a slag unloading position along a second direction (backward direction) opposite to the first direction (forward direction), so that the slag pushing component 220 rotates to the state of pushing slag. Through setting up spacing subassembly 240, can make according to the operating condition of system of making coffee machine, carry on spacingly or remove spacingly to pushing away sediment subassembly 220, make and push away sediment subassembly 220 can keep waiting outside the inner chamber and push away the sediment state, can rotate again to the sediment state of pushing away that gets into the inner chamber.

The residue pushing mechanism provided by the embodiment of the invention pushes the residue pushing assembly 220 to switch between the residue pushing state and the residue state to be pushed by means of the power of the motion of the screw rod assembly 300, and the state of the residue pushing assembly 220 is associated with the working state of the brewing system of the coffee machine, so that the residue pushing mechanism is ingenious in structural design, not only can realize smooth residue unloading, but also can save a power mechanism, simplify the structure and reduce the cost.

In some embodiments, as shown in fig. 1 and 3, the slag pushing assembly 220 includes a rotating shaft 221 and a pushing plate 222 fixed to the rotating shaft 221 and extending in a radial direction of the rotating shaft 221. The rotating shaft 221 is rotatably disposed on the base 210, and an axial direction of the rotating shaft 221 is the same as a moving direction of the screw rod assembly 300. As shown in fig. 4 and 5, an opening 620 communicating with the inner cavity of the body 600 is provided on the upper plate 610 of the body 600. When the rotating shaft 221 rotates, the pushing plate 222 is driven to enter and exit the inner cavity through the opening 620, so as to switch between a slag pushing state and a slag waiting state. It will be appreciated that the state of the slag pushing assembly 220 is actually the state of the push plate 222. The pushing plate 222 is shown in a slag pushing state in fig. 4, and the pushing plate 222 is shown in a state to be pushed in fig. 5. This push away sediment subassembly 220 realizes rotating through pivot 221, realizes pushing away the sediment through push pedal 222, forms the structure of similar swing arm, not only pushes away the sediment effectual, and simple structure is reasonable moreover, and the space occupies lessly.

In some embodiments, as shown in fig. 1 and 6, the pushing member 230 is a rod-shaped body formed by extending the screw rod assembly 300 along a first direction, a free end of the rod-shaped body has a first inclined surface 231, the slag pushing assembly 220 is provided with a second inclined surface 224, when the pushing member 230 moves along the first direction with the screw rod assembly 300, the first inclined surface 231 of the pushing member 230 acts on the second inclined surface 224 of the slag pushing assembly 220, and the slag pushing assembly 220 is pushed to rotate so as to be switched from the slag pushing state to the slag waiting state. The pushing member 230 is integrally formed on the lead screw assembly 300, so that the structure can be simplified and the structural strength can be enhanced. And through the matched inclined plane structure, the pushing of the slag pushing assembly 220 in the moving process of the screw rod assembly 300 is facilitated to realize the state switching.

The second inclined surface 224 may be directly formed on a side of the push plate 222 facing the rear end of the machine body 600, or a protrusion 223 may be disposed at a connection position of the push plate 222 and the rotating shaft 221, the protrusion 223 is connected with the rotating shaft 221, and the second inclined surface 224 is formed on a side of the protrusion 223 facing the rear end of the machine body 600, as shown in fig. 3.

The screw rod assembly 300 drives the pushing member 230 to advance and gradually approach the slag pushing assembly 220, so that the first inclined surface 231 of the pushing member 230 contacts the second inclined surface 224 of the slag pushing assembly 220, as shown in fig. 7 and 8, at this time, the pushing member 230 is in a state of pushing the slag pushing assembly 220. The pushing member 230 rotates to the direction that the pushing plate 222 rotates out of the inner cavity as the lead screw assembly 300 continues to advance, and meanwhile, the pushing member 230 goes over the second inclined surface 224 and enters the lower part of the pushing plate 222, as shown in fig. 9 and 10. Thus, the slag pushing assembly 220 is switched from the slag pushing state to the slag to be pushed.

In some embodiments, as shown in fig. 3, an end (defined as a first end for convenience of description below) of the rotation shaft 221 facing the second direction (a direction facing the rear end of the body 600) is provided with a third slope 225. As shown in fig. 11, a fourth slope 213 is provided in the base 210 to match the third slope 225. When the pushing component 230 moves along with the screw rod assembly 300 until the first inclined surface 231 of the pushing component acts on the second inclined surface 224 of the slag pushing assembly 220, the pushing slag pushing assembly 220 is pushed to rotate, and when the slag pushing assembly 220 rotates, the fourth inclined surface 213 applies acting force to the third inclined surface 225 to push the rotating shaft 221 to move towards the first direction, so that the pushing plate 222 and the limiting assembly 240 are dislocated, the limiting assembly 240 avoids the pushing plate 222, and the pushing plate 222 can rotate to a state of waiting for slag pushing. Through the arrangement of the third inclined surface 225 and the fourth inclined surface 213 which are matched with each other, the slag pushing assembly 220 moves while rotating to avoid the limiting assembly 240, and the limiting assembly 240 is prevented from influencing the rotation thereof.

Specifically, as shown in fig. 11, a rotating shaft cavity 211 is formed in the base 210, an arc-shaped protrusion 212 that is adapted to a circumferential surface of a first end of the rotating shaft 221 is formed at one end of the rotating shaft cavity 211, and a fourth inclined surface 213 is formed on one side of the arc-shaped protrusion 212 facing the second direction. As shown in fig. 3, the first end of the rotating shaft 221 is partially cut in the circumferential direction to form a notch, the end of the notch on one side in the axial direction forms a third inclined surface 225, the arc-shaped protrusion 212 is inserted into the notch, and the fourth inclined surface 213 is matched with the third inclined surface 225. Thus, when the pushing component 230 pushes the pushing assembly 220, the pushing assembly rotates and moves axially due to the fourth inclined surface 213. The rotation causes the push plate 222 to exit the cavity and the movement causes the push plate 222 to clear the stop assembly 240 and continue to rotate. The design concept is ingenious, and rotation and movement are achieved through a simple structure.

In some embodiments, as shown in fig. 3, in conjunction with fig. 12 and 13, the slag pushing assembly 220 further comprises a first resilient member 226. The first elastic member 226 acts on the rotating shaft 221, and is used for applying a force to the rotating shaft 221 to move the rotating shaft 221 towards the second direction, so that when the pushing member 230 releases the pushing of the slag pushing assembly 220, the rotating shaft 221 moves to a position opposite to the limiting assembly 240 along the second direction, and is limited and kept in a state of waiting for slag pushing by the limiting assembly 240. The first elastic member 226 can enable the slag pushing assembly 220 to automatically reset to a position which can be limited by the limiting assembly 240, so that the slag pushing assembly 220 is kept in a state of waiting for slag pushing. The limiting component 240 is skillfully matched with the slag pushing component 220.

In some embodiments, as shown in fig. 12 and 13, the limiting assembly 240 includes a sliding bar 241, a toggle block 242, and a second elastic member 243. The sliding bar 241 is provided on the base 210 and is capable of sliding along the base 210 in a moving direction of the screw assembly 300 (i.e., an axial direction of the sliding bar 241). The dial block 242 is disposed at one end of the sliding rod 241 and located outside the base 210, and the other end of the sliding rod 241 forms a stopper 245. For example, the dial block 242 may be fixed to one end of the sliding bar 241 by a bolt 244. The slider 241 reciprocates in the axial direction thereof and can be switched between a limit state and a limit release state. That is, when the slide lever 241 moves in the direction toward the push plate 222, the slide lever 241 stops and positions the push plate 222 in a position-limited state, and at this time, the push plate 222 cannot rotate and is kept in a state to be pushed, and when the slide lever 241 moves in the direction away from the push plate 222, the slide lever 241 is separated from the push plate 222, and the position-limited state is released by releasing the position-limited state of the push plate 222. Specifically, the force of the slide bar 241 moving toward the push plate 222 is provided by the second elastic member 243, and the force of the slide bar 241 moving away from the push plate 222 is provided by the toggle block 242. The second elastic member 243 is used for applying a force to the sliding rod 241 to make the sliding rod move towards the first direction (i.e. away from the push plate 222), so as to limit the push plate 222 in a state of pushing the slag. When the toggle block 242 receives the acting force toward the second direction, the sliding rod 241 is driven to move along the second direction (i.e. the direction away from the push plate 222), so that the limiting portion 245 of the sliding rod 241 is separated from the push plate 222 to release the limitation of the slag pushing assembly 220. Above-mentioned spacing subassembly 240's simple structure is reasonable, and the action process is smooth and easy, does benefit to spacing and the removal is spacing to push pedal 222.

Further, as shown in fig. 6, the screw assembly 300 is provided with a sliding groove 310 extending along the moving direction thereof. One end of the sliding chute 310 in the first direction is sealed to form a stopping part 320. The toggle block 242 penetrates through the upper plate 610 of the machine body 600 and extends into the sliding slot 310, and when the screw rod assembly 300 moves to the stopping portion 320 of the sliding slot 310 along the second direction and abuts against the toggle block 242, the toggle block 242 and the sliding rod 241 are driven to move together along the second direction, so that the sliding rod 241 is separated from the push plate 222. The toggle block 242 of the limiting component 240 is associated with the screw rod component 300, and the power of the movement of the screw rod component 300 is utilized to drive the sliding rod 241 to retreat to remove the limitation of the push plate 222, so that the independent arrangement of a power source can be avoided, the structure is simplified, and the cost is reduced.

Further, as shown in fig. 3, 12 and 13, a torsion spring 227 is disposed on the rotating shaft 221, and the torsion spring 227 is used for applying an acting force to the slag pushing assembly 220 to switch from the state of waiting for slag pushing to the state of slag pushing. When the limiting assembly 240 retreats under the driving of the screw rod assembly 300 and is separated from the push plate 222, the rotating shaft 221 rotates under the action of the torsion spring 227, so that the push plate 222 automatically rotates to a slag pushing state, and automatic slag pushing is realized.

Further, a guide block 214 is disposed on the base 210, see fig. 4. The lead screw assembly 300 is provided with a guide groove 330 extending in a moving direction thereof. The guide block 214 extends into the guide groove 330 through the upper plate 610 of the body 600 to guide the movement of the screw assembly 300 in the inner cavity of the body 600, ensuring that the screw assembly 300 moves in a predetermined direction without deviation.

The residue pushing mechanism provided by the embodiment of the invention can automatically push residues after coffee brewing is finished, ensures that a brewing system of the coffee machine smoothly unloads the residues, and has the advantages of simple structure, reliability and practicability.

The embodiment of the invention also provides a brewing system of the coffee machine.
