Fig. 6 is a partial cross-sectional view of a brewing positioning mechanism portion of an embodiment of the present invention.

As shown in fig. 3, 5 and 6, the brewing positioning mechanism 4 includes a frame 41, a driving unit 42, a screw 43, a brewing chamber 44 and a stopper 45.

The frame 41 has a rectangular parallelepiped frame structure, and is disposed in the housing 1 and fixed to the housing 1.

The front top of the frame 41 is provided with an inlet channel 41A with a shape corresponding to the beverage material cup 11, and the position of the inlet channel 41A corresponds to the material cup channel 22, so the beverage material cup 200 can slide down after passing through the material cup channel 22, and then enter the frame 41. In this embodiment, the inner walls of the two sides of the inlet channel 41A are respectively provided with a frame side cup sliding slot 411 extending along the vertical direction, the positions of the frame side cup sliding slots 411 respectively correspond to the channel side cup sliding slots 221 and are communicated with the corresponding channel side cup sliding slots 221, when the beverage material cup 200 slides down to the bottom end of the material cup channel 22 under the guidance of the channel side cup sliding slots 221, the beverage material cup can slide down continuously under the guidance of the frame side cup sliding slots 411. Meanwhile, a waste channel 41B extending downward is further provided at the front bottom of the frame 41, and the waste channel 41B is located below the stopper 45.

The two limiting members 45 are respectively disposed on the inner walls of the two sides of the frame body 41 and located at the bottom end of the channel cup sliding groove 221.

Fig. 7 is a schematic structural diagram of a limiting member according to an embodiment of the invention.

As shown in fig. 3 and 7, the stopper 45 is a groove-shaped member having a vertically extending stopper groove 451, a lower portion of a side inner surface 451A of the stopper groove 451 is curved, and a front inner surface 451B (i.e., a side surface closer to the filter member 5 and farther from the brewing chamber 44) is inclined.

The two stoppers 45 are provided to face each other on the frame 41 so that the stopper grooves 451 face each other. The frame 41 at the upper and lower ends of each stopper 45 is provided with a guide post (not shown), and each guide post extends in the horizontal direction and has a length direction perpendicular to the front-rear direction. Each guide post has a guide groove portion extending in the longitudinal direction thereof, and upper and lower ends of the stopper 45 are movably fitted in the guide groove portions, respectively, so that the stopper 45 can reciprocate in the direction perpendicular to the front-rear direction under the guide action of the guide post, that is, in the direction perpendicular to the front-rear direction. When the two stoppers 45 move simultaneously in the direction perpendicular to the front-rear direction, they move away from or close to each other.

In the present embodiment, a return spring (not shown) is further connected to the stopper 45, and the other end of the return spring is fixed to the frame 41 so that the stopper 45 is held at a certain position (hereinafter, this position is referred to as an initial position) when not being subjected to an external force. When the two limiting members 45 are both located at the initial position, the distance between the limiting members 45 is the smallest.

As shown in fig. 3 and 5, when the limiting member 45 is located at the initial position, the upper end of the limiting member is abutted against the frame-side cup sliding slot 411, and at this time, the limiting slot 45 is aligned with the frame-side cup sliding slot 411, so that when the beverage material cup 200 slides down to the bottom end of the frame-side cup sliding slot 411 under the guidance of the channel-side cup sliding slot 221 and the frame-side cup sliding slot 411, the beverage material cup can continuously slide down to enable the two side portions of the brim 203 to enter the limiting slot 451.

Fig. 8 is a schematic diagram of a top view of a position limiter for limiting a beverage material cup according to an embodiment of the present invention, and fig. 9 is a schematic diagram of a front view of a position limiter for limiting a beverage material cup according to an embodiment of the present invention. Wherein, fig. 8(a) is a schematic diagram of the beverage material cup in a limit state at a side view angle, and fig. 8(b) is a schematic diagram of the beverage material cup in a limit releasing state at a front view angle; fig. 9(a) is a schematic view of the beverage material cup in a limit state at a side view angle, and fig. 9(b) is a schematic view of the beverage material cup in a limit released state at a front view angle.

As shown in fig. 3, 8(a) and 9(a), after the two side portions of the brim 203 enter the limiting grooves 451, since the lower portions of the inner surfaces 451A of the side portions are curved surfaces which are bent inward, when the cup is in the initial position, the distance between the bottom ends of the two limiting grooves 451 is smaller than the diameter of the brim 203, and the brim 203 is limited to be clamped by the two limiting members 45 and cannot move; when the beverage material cup 200 moves in the front direction (i.e., the direction of arrow F1 in the figure) under the action of external force, since the front inner surface 451B is inclined, when the two side edges of the brim 203 abut against the front inner surface 451B and continue to move forward, the two position-limiting members 45 are simultaneously pushed in the direction away from each other (i.e., the direction of arrows F2 and F3 in the figure), and finally the position-limiting groove 451 is separated from the front-most position of the front inner surface 451B, i.e., the state where the position-limiting members 45 are separated is presented, as shown in fig. 8(B) and 9 (B). In this state, if the beverage material cup 200 continues to move forward under the action of external force, the cup brim 203 will cross the whole stopper 45, and the stopper 45 will return to the initial position under the action of the return spring. At this time, even if the beverage material cup 200 moves backward again by an external force, only the rear surfaces of both sides of the brim 203 abut against the front outer surface of the stopper 45, and the brim 203 cannot return to the stopper groove 451. That is, the beverage material cup 200 can move only in the forward direction in one direction and cannot move in the backward direction after sliding down into the stopper groove 451 through the passage-side cup chute 221 and the frame-side cup chute 411 by the engagement of the stopper 45, the guide post, and the return spring.

The driving unit 42 is a micro motor fixedly provided at a rear outside position of the frame 41.

The lead screw 43 extends horizontally in the front-rear direction, and the lead screw 43 is connected to the output end of the driving unit 42 so as to be rotatable by the driving unit 42.

The brew chamber 44 has a side wall 441, a receptacle 442, and a rear wall 443.

In this embodiment, the inner walls of the two sides of the frame 41 are further provided with brewing chutes 412 extending along the front-back direction. A plurality of sliders (not shown) are disposed on both sides of the sidewall 441 and engaged with the brewing chamber chutes 412, and the sliders are respectively inserted into the brewing chamber chutes 412, so that the brewing chamber 44 is movably mounted on the frame 41 in the front-rear direction.

The side wall 441 is externally provided with a threaded portion 444 on the top side thereof for engagement with the lead screw 43, the threaded portion 444 being provided with an internal thread for engagement with the lead screw 43. Thus, when the screw 43 is driven by the driving unit 42 to rotate, the brewing chamber 44 can move back and forth integrally by the thread fit between the thread portion 444 and the screw 43. That is, the screw 43 and the driving unit 42 constitute a driving portion that drives the brewing chamber 44 to move linearly in the front-rear direction.

The receiving portion 442 is surrounded by the side wall 441 and the rear wall 443, and has a shape corresponding to the cup 201. The front of the receiving portion 442 is open, so that when the beverage material cup 200 is located at the front side of the brewing chamber 44 and the position of the beverage material cup corresponds to the opening of the receiving portion 442, the brewing chamber 44 moves forward to allow the beverage material cup 200 to be received in the receiving portion 442, so that when the brewing chamber 44 moves forward, the beverage material cup 200 is abutted by the receiving portion 442 and is driven to move forward. Since the receiving portion 442 is open at the front, there is no part that can abut against the cup 201 or the lid 202 from the front side, and therefore, when the brewing chamber 44 moves backward in the received state, the beverage material cup 200 is no longer moved by the receiving portion 442, that is, can be separated from the receiving portion 442.

The rear wall 443 is provided with a water injection needle 445 that penetrates the rear wall 443 and extends into the housing 442, and the water injection needle 445 is pointed at one end located in the housing 442 and is communicated with a water supply line of the water supply unit 3 (the water supply line is not shown) at one end extending to the rear of the rear wall 443.

As shown in fig. 3 and 5, the filter mechanism 5 is provided in the housing 1 at an upper front position.

The filter mechanism 5 includes a bottom plate 51 corresponding to the shape of the cap 202 and a plurality of piercing members 52 provided on the bottom plate 51.

The chassis 51 is in the shape of a vertically extending disk, and is located at a front position of the stopper 45. In the horizontal direction, the position of the chassis 51 in the horizontal direction corresponds to the accommodating portion 442, i.e., the center points of both are on the same horizontal line in the front-rear direction.

The piercing members 52 are each of a thorn-like configuration with the pointed portion thereof facing the rear side (i.e., toward the brewing chamber 44), and each piercing member 52 is provided with a filter aperture 53 at the junction with the bottom plate 51. When the beverage material cup 200 is received in the receiving portion 442 and pressed toward the filter mechanism 5 with the brewing chamber 44 moving forward, the lid 202 is pierced by the piercing member 52, so that the beverage in the cup body 201 flows out of the filter hole 53 through the piercing member 52.

In this embodiment, the front side of the housing 1 is provided with a protrusion 11, and the protrusion 11 is located above the drip tray 6.

The lower part of the protruding part 11 is provided with a water outlet 12 with a downward opening, the chassis 51 is provided with a beverage channel 522 communicated with each filtering hole 53, and the beverage channel 522 is communicated with the water outlet 12, so that the beverage finally flows into a cup (the cup is not shown in the figure) placed on the drip tray 6 from the water outlet 11. In addition, a switch 13 is arranged on the upper side of the convex part 11, and when a user presses the switch 13, the beverage brewing program can be started.

The raw material cup collecting part 7 is detachably arranged at the lower part of the front side of the shell 1, is of a cylindrical structure with a semicircular section, and the upper part of the raw material cup collecting part is provided with a collecting part opening 7A. The collecting portion opening 7A is located below the waste channel 41B so that the drink material cup 200 can fall therein.

The handle 8 is in a belt shape, two ends of the handle are respectively hinged on the shell 1, and a user can lift the handle 8, so that the beverage brewing machine 100 is integrally lifted.

The control section controls the operation of the lid opening motor, the drive unit 42, and the water supply section 3. In the present embodiment, the control portion is a circuit board having a control chip and a corresponding control circuit, and the circuit board is disposed in a circuit board compartment 14 at the lower rear portion in the housing 1. In this embodiment, a plurality of position sensing elements electrically connected to the control portion are further disposed in the frame 41, and are used for sensing whether the beverage material cup 200 reaches a corresponding position and generating a corresponding electrical signal, including: after the beverage material cup 200 is put into the material cup channel 22, sensing whether the beverage material cup 200 slides down to reach the position of the limiting part 45; in the process that the drink material cup 200 is carried to the filtering member 5 by the brewing chamber 44, it is sensed whether the drink material cup 200 has reached a predetermined brewing position (i.e., the lid 202 abuts against the bottom plate 51, in which state the lid 202 has been pierced by the piercing member and the bottom of the cup 203 has been pierced by the filling needle 445). These position sensing elements may be infrared sensors, proximity switches, pressure sensors, or the like, and are provided near the stopper 45 or near the chassis 51. The sensing element for sensing whether the beverage material cup 200 slides down to reach the position of the limiting member 45 is referred to as a first sensing element, and the sensing element for sensing whether the beverage material cup 200 reaches the predetermined brewing position is referred to as a second sensing element.

The operation of the beverage brewing machine 100 according to the present invention will be described with reference to the accompanying drawings.

Before brewing begins, the brewing chamber 44 is located at a rearward position as shown in fig. 3 and 6 so that the side wall 441 and the like are not exposed below the material cup passage 22 and do not impede the downward sliding of the beverage material cup 200.

When a user presses the button switch 13, the control part firstly controls the cover opening motor to drive the cover part 21 to rotate and open according to the electric signal of the switch 13, the raw material cup channel 22 is exposed, and at the moment, the user can put the beverage raw material cup 200 into the raw material cup channel 22 according to the direction that the cup cover 202 faces the front side and the bottom of the cup body 203 faces the rear side, so that the beverage raw material cup 200 slides downwards to the position of the limiting part 45 under the guide of the channel side cup sliding groove 221 and the frame side cup sliding groove 411.

Once the control portion receives the electric signal generated by the first sensing element corresponding to the position where the beverage material cup 200 has slid down to the stopper 45, the control portion controls the driving unit 42 to drive the screw 43 to rotate, so that the brewing chamber 44 moves forward. Since the stopper 45 is actually located between the brewing chamber 44 and the filter member 5, when the brewing chamber 44 moves forward (i.e. toward the filter member 5) under the driving of the driving portion, the beverage material cup 200 is accommodated by the accommodating portion 442 to follow the brewing chamber 44 to move forward. In the process, the beverage material cup 200 pushes the position-limiting member 45 away in both directions (i.e., the directions of arrows F2 and F3), disengages from the position-limiting member 45, and continues to move forward. When the drink material cup 200 reaches the filtering member 5 but the lid 203 is not pierced, since the brewing chamber 44 still moves forward, the drink material cup 200 will move forward to pierce the lid 202 by the piercing member 52, and the bottom of the cup body 201 is pierced by the filling needle 445, so that the drink material cup 200 finally reaches a state where the lid 202 abuts against the bottom plate 51. At this time, since the cup body 201 is inserted by the filling needle 445 and the cap 202 is pierced by the piercing member 52, the filling and brewing process can be started, and thus the beverage material cup 200 reaches the predetermined brewing position in this state.

Once the control part receives the electrical signal generated by the second sensing element and corresponding to the cup cover 202 abutting against the chassis 51, the control part controls the water supply part 3 to supply hot water for brewing into the beverage material cup 200 through the water injection needle 445 so as to brew, and the brewed beverage flows out through the water outlet 12.

After a predetermined brewing time (which can be calculated according to a predetermined brewing amount, the flow rate of the water pump in the water supply part 3, and the like), the control part controls the water supply part 3 to stop supplying hot water, and controls the driving unit 42 to drive the screw 43 to rotate in the reverse direction, so that the brewing chamber 44 moves backward and returns to the backward position before the brewing starts. In the process, the beverage material cup 200 will initially move slightly backwards under the drive of the filling needle 445, so that the cap 202 is first removed from the filter member 5. After the beverage material cup 200 reaches the position-limiting member 45, it is limited by the position-limiting member 45 and cannot move backward along with the containing portion 442. In this state, the water injection needle 445 continues to move backward along with the brewing chamber, and is separated from the drink material cup 200, the drink material cup 200 loses its support, and falls into the material cup collecting portion 7 from the waste passage 41B and the collecting portion opening 7A, and the whole brewing process is completed.

Effects and effects of the embodiments

According to the brewing positioning mechanism and the beverage preparation machine provided by the embodiment, the top of the frame body is provided with the inlet channel, the position of the bottom end of the inlet channel is provided with the limiting part, and the beverage material cup can be placed into the brewing positioning mechanism from the upper part and limited at the position of the limiting part; meanwhile, the filtering mechanism is positioned between the limiting part and the brewing bin, and the driving part only needs to drive the brewing bin to move linearly, so that the accommodating part in the brewing bin can drive the beverage raw material cup to move, and the beverage raw material cup reaches a brewing preset position at the filtering mechanism. Therefore, in the brewing positioning mechanism of the embodiment, the beverage material cup naturally moves downwards in the vertical direction by means of gravity, and the driving part and the brewing bin only need to move linearly to achieve brewing positioning.

In the embodiment, the two limiting parts are arranged in opposite directions and can be close to or far away from each other, the lower side part of the inner surface of the side part of the limiting groove in each limiting part is a curved surface, and the distance between the bottom ends of the limiting grooves is smaller than the diameter of the cup brim, so that the limiting parts can clamp and limit the beverage raw material cup when the beverage raw material cup slides downwards, and the limiting parts can be far away from each other to separate the beverage raw material cup when the brewing bin drives the beverage raw material cup to move forwards. Furthermore, the limiting part can also limit the beverage raw material cup again when the brewing bin moves backwards so as to prevent the beverage raw material cup from moving backwards due to the driving of the water injection needle. Therefore, the embodiment adopts a simple structure to realize three functions of limiting in the vertical direction after the beverage raw material cup slides downwards, separating from the limiting during brewing and limiting again in the horizontal direction after brewing is finished, and the beverage raw material cup moves in the sequence of sliding downwards, moving forwards, moving backwards and falling under the matching of the inlet channel and the brewing bin to finish the whole brewing process.

In the embodiment, because the frame body is provided with the abandonment passageway that is located the locating part below, still be equipped with raw materials cup collection portion below the abandonment passageway, therefore dash and steep the completion back, the drink raw materials cup that finishes can directly fall into raw materials cup collection portion, need not set up other removal drink raw materials cup's that finishes structure, also need not the user manually to take out drink raw materials cup.

The above embodiments are preferred examples of the present invention, and are not intended to limit the scope of the present invention.

For example, in an embodiment, the limiting groove of the limiting member can allow the cup brim to enter, and the limiting groove limits the position of the beverage raw material cup by limiting the cup brim. However, in the present invention, when the beverage material cup does not have a brim, the width of the limiting groove in the horizontal direction may be set to be the same as the thickness of the beverage material cup, so that the limiting member can also limit the beverage material cup.

In an embodiment, the limiting member is movably mounted on the frame body through the guide post, and in the present invention, the limiting member may also be movably mounted on the frame body through other manners, such as directly providing a guide slot portion on the frame body and allowing the limiting member to be embedded into the guide slot portion.

In addition, in the embodiment, the circuit board bin is arranged at the lower part of the rear side of the shell, a vacant space is still reserved at the position, and a water tank for storing cold water can be arranged according to the requirement; in addition, the storage bin can be replaced by a water tank, so that the beverage preparation machine is more convenient to use.
