Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of coffee machines, and particularly relates to a leakage-stopping valve lifting control mechanism and a drip coffee machine. BACKGROUND

[0002] Most drip coffee machines on the market are provided with a leakage-stopping valve, but the leakage-stopping valve generally needs to be lifted by a cup of a specific height placed on the base of the drip coffee machine. When the leakage-stopping valve is lifted, it is opened, and the brewed coffee liquid in the funnel assembly flows out into the cup. When the cup is removed from the base, the leakage-stopping valve automatically falls back and is closed, and the coffee liquid in the funnel assembly no longer flows out. The drip coffee machine of this structure can only use a specific cup, and other cups cannot be used, which brings great inconvenience to the user. In order to overcome the above problems, some drip coffee machines with a leakage-stopping valve with lifting function have also appeared, but the lifting of the leakage-stopping valve needs to be manually adjusted, which is not convenient to operate and has low control precision. CONTENT OF THE UTILITY MODEL

[0003] In view of one of the above problems existing in the prior art, the purpose of the embodiments of the present application is to provide a leakage-stopping valve lifting control mechanism and a drip coffee machine.

[0004] The technical solution adopted by the embodiments of the present application is a leakage-stopping valve lifting control mechanism for a drip coffee machine, which comprises:

[0005] A rotating head, which is provided with a first sliding rail thereon;

[0006] A push rod, which is arranged transversely, and a first end of the push rod is opposite to the rotating head;

[0007] A leakage-stopping support, a first end of which faces a leakage-stopping valve of the drip coffee machine, and a second end of which is opposite to a second end of the push rod;

[0008] A driving component, which is connected with the rotating head, is used to drive the rotating head to rotate and control the rotation angle of the rotating head, so that when the rotating head rotates, one end of the push rod can slide up or slide down the first sliding rail, and the second end of the push rod can push the leakage-stopping support to move in the direction towards the leakage-stopping valve, so that the leakage-stopping valve is lifted by the second end of the push rod and kept at different height positions. The embodiments of the present application can realize the automatic lifting of the leakage-stopping valve, can adapt to cups (containers) of different heights, and do not need to use a specific cup placed on the drip coffee machine to trigger the opening of the leakage-stopping valve.

[0009] Optionally, one end of the first slide rail is provided with a first guide slide slope; the first end of the leak stop support is provided with a second guide slide slope; when the driving component drives the rotating head to rotate, the first end of the push rod can slide up or slide down the first guide slide slope of the first slide rail, so that the push rod moves towards the direction of approaching or moving away from the leak stop support, and pushes the leak stop support to move towards the direction of the leak stop valve or cancels the pushing of the leak stop support, so that the leak stop support can move towards the direction of moving away from the leak stop valve, and when the leak stop support moves towards the direction of the leak stop valve, the leak stop valve is gradually lifted to different height positions by the second guide slide slope on the leak stop support. By controlling the rotation angle of the rotating head, the height of the leak stop valve can be controlled, and then the dripping speed can be controlled to make different flavors of coffee.

[0010] Optionally, the leak stop valve lifting control mechanism further comprises a top rod and a travel switch, the top rod is vertically arranged, and a plurality of convex points are sequentially arranged on the top rod along the length direction of the top rod.

[0011] The rotating head is further provided with a second spiral slide rail, and the lower end of the top rod abuts against the spiral surface of the second slide rail. When the rotating head rotates, the second slide rail can push the top rod to move up and down, and when the top rod moves up and down, the plurality of convex points on the top rod can sequentially trigger the travel switch, so that the travel switch generates different trigger signals respectively, and when different convex points trigger the travel switch, the leak stop support pushes the leak stop valve to be lifted to a specified height position.

[0012] The driving component is a stepping motor, the stepping motor and the travel switch are connected with the electronic board, the electronic board receives the trigger signals generated by the travel switch, and controls the stepping motor to stop rotating. In this way, by additionally arranging the top rod and the travel switch, the height position of the leak stop valve can be further accurately controlled.

[0013] Optionally, the convex points comprise a first convex point, a second convex point and a third convex point arranged from top to bottom.

[0014] When the rotating head rotates to the first convex point triggering the travel switch, the first end of the push rod slides down from the first guide slide slope, the leak stop valve is located at the lower part of the second guide slide slope of the leak stop support, and is in a closed state.

[0015] When the rotating head rotates to the second convex point triggering the travel switch, the first end of the push rod slides up the middle part of the first guide slide slope, the leak stop valve is located at the middle part of the second guide slide slope of the leak stop support, and is in a first open state.

[0016] When the rotating head rotates to the third convex point triggering the travel switch, the first end of the push rod slides on the upper part of the first guide slope, and the leak stop valve is located on the upper part of the second guide slope of the leak stop support and is in the second open state;

[0017] Wherein, the opening degree of the leak stop valve in the first open state is smaller than that in the second open state. By lifting the leak stop valve to different intermediate positions or high positions, the dripping speed of coffee liquid can be controlled, thereby obtaining two different flavors of coffee.

[0018] In an optional embodiment, the rotating head comprises a main body, and the main body has a disc-shaped surface arranged vertically on the side facing the leak stop valve; the first slide rail and the second slide rail are arranged on the disc-shaped surface, and the first slide rail is arranged near the periphery of the disc-shaped surface and has a circular arc shape; the second slide rail is arranged near the center of the disc-shaped surface and gradually extends outward from the center of the disc-shaped surface, so that the radius of the circle in which the second slide rail is located is larger as the second slide rail is farther away from the center. In this way, the push rod and the top rod can be simultaneously pushed to move when the rotating head rotates.

[0019] In an optional embodiment, the leak stop support comprises two support legs arranged in a spreader shape, and the front ends of the two support legs are respectively formed with the second guide slope; the leak stop valve has slide rods protruding outward from opposite sides, and the two slide rods are respectively arranged on the second guide slopes of the two support legs and can slide up or slide down along the second guide slopes when the leak stop support is pushed by the rotating head.

[0020] In an optional embodiment, the leak stop valve is provided with a reset component, and the reset component is used to apply a downward movement force to the leak stop valve, so that when the rotating head rotates to the position where the push rod slides down from the first guide slope and the pushing effect on the leak stop support is cancelled, the reset component can push the leak stop valve to move downward to the closed state, and the leak stop valve moves downward to push the leak stop support to move away from the leak stop valve.

[0021] A drip coffee machine comprises a machine body, a top cover assembly arranged on the machine body, and a funnel assembly arranged on the top cover assembly, and further comprises the leak stop valve lifting control mechanism in any of the above embodiments, wherein the leak stop valve lifting control mechanism is arranged on the funnel assembly and is used to drive the leak stop valve on the funnel assembly to lift or lower, so as to change the opening degree of the leak stop valve.

[0022] In an optional embodiment, the funnel assembly comprises a funnel support and a funnel detachably arranged on the funnel support, a top rod slot is arranged on the top periphery of the funnel, and a top rod hole is arranged on the funnel support and opposite to the top rod slot; when the rotating head rotates to push the stop valve to be lifted, the upper end of the top rod extends into the top rod slot through the top rod hole, so as to lock the funnel on the funnel support; when the rotating head rotates to release the pushing of the stop valve by the push rod, the stop valve is in the low position and closed, and the upper end of the top rod is out of the top rod slot and the top rod hole, so as to release the locking of the funnel on the funnel support. The stop valve lifting control mechanism can not only control the lifting of the stop valve to realize the opening and closing and the adjustment of the opening degree, but also can realize the locking and unlocking of the funnel on the funnel support, which is ingenious in structure design and convenient to use.

[0023] Compared with the prior art, the beneficial effects of the embodiment of the application are that the stop valve lifting control mechanism can realize the automatic lifting of the stop valve, without using a cup (container) of a specific height to lift the stop valve to be opened, so that it can be adapted to cups of different heights. Moreover, the lifting height of the stop valve has at least two gears: the middle gear and the high gear, which can realize the preparation of at least two different flavors of coffee.

DETAILED DESCRIPTION

[0045] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme of the embodiments of the present application will be described clearly and completely below with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application.

[0047] In order to keep the following description of the embodiments of the present application clear and brief, the present application omits the detailed description of known functions and known components.

[0048] The embodiments of the present application disclose a leakage stop valve lifting control mechanism for a drip coffee machine, which is used to control the lifting of the leakage stop valve 97 of the hopper assembly on the drip coffee machine. The lifting of the leakage stop valve 97 can change the opening and closing state and adjust the opening degree when the opening state is changed.

[0049] As Figure 1 shown, the drip coffee maker according to the present application comprises a rotating head 1, a push rod 2, a drip stopper bracket 3 and a driving component 4. The rotating head 1 is provided with a first slide rail 12. The push rod 2 is horizontally arranged, and a first end of the push rod 2 is opposite to the rotating head 1. The drip stopper bracket 3 has a first end facing a drip stopper 97 of the drip coffee maker, and a second end opposite to a second end of the push rod 2, as shown in Figure 2 、 Figure 5 and Figure 8 . The driving component 4 is connected with the rotating head 1, for driving the rotating head 1 to rotate back and forth, and for making one end of the push rod 2 slide up or slide down the first slide rail 12, and for enabling the second end of the push rod 2 to push the drip stopper bracket 3 to move in a direction towards the drip stopper 97, so that the push rod 2 lifts the drip stopper 97 up and keeps it at different height positions by means of the second end. When the drip stopper 97 is lifted up, it is in an open state, and coffee liquid in a funnel assembly can flow out through the drip stopper 97.

[0050] The present application controls the rotating angle of the rotating head 1 by means of the driving component 4, and according to the rotating angle of the rotating head 1, the lifting height of the drip stopper 97 can be determined, so as to precisely control the opening degree of the drip stopper 97, and the drip stopper 97 can be lifted up and kept at different height positions, so that the drip stopper 97 has different opening degrees, and thus the drip speed is different, so as to make coffee with different tastes. The opening of the drip stopper 97 does not need to use a cup placed on a base 71 of the drip coffee maker to lift up, so that the cup does not have specific requirements, and the cup only needs to be able to receive the coffee liquid flowing out of the drip stopper 97, for example, a coffee cup, a coffee pot, a mug, a glass, etc.

[0051] In some embodiments, as Figure 10 shown, one end of the first slide rail 12 is provided with a first slide guiding inclined surface 121. As Figure 11As shown, the first end of the leakage stop bracket 3 is provided with a second guide slope 311. When the driving component 4 drives the rotary head 1 to rotate, the first end of the push rod 2 can slide up or slide down the first guide slope 121 of the first slide rail 12, so as to drive the push rod 2 to move towards the leakage stop bracket 3 or away from the leakage stop bracket 3, and drive the leakage stop bracket 3 to move towards the leakage stop valve 97 or cancel the driving of the leakage stop bracket 3, so that the leakage stop bracket 3 can move away from the leakage stop valve 97. When the first end of the push rod 2 slides up the first guide slope 121, the second end of the push rod 2 pushes against the leakage stop bracket 3, so that the leakage stop bracket 3 moves towards the leakage stop valve 97, and the leakage stop bracket 3 gradually lifts the leakage stop valve 97 through the second guide slope 311 thereon. According to different rotation angles of the rotary head 1, the height at which the first end of the push rod 2 slides up the first guide slope 121 is different, so that the distance by which the leakage stop bracket 3 is driven to move towards the leakage stop valve 97 is different, and the height by which the leakage stop valve 97 is lifted is different. Therefore, by controlling the rotation angle of the rotary head 1, the height by which the leakage stop valve 97 is lifted can be controlled, and then the dripping speed can be controlled.

[0052] The driving component 4 can adopt a motor, and the rotation angle of the rotary head 1 can be determined by controlling the starting time length of the motor. For example, when the motor is started for a first time length, the leakage stop valve 97 is lifted to a first height position and is in a first opening state. At this time, if the motor is stopped, the leakage stop valve 97 remains at the first height position. When the motor is started for a second time length, the leakage stop valve 97 is lifted to a second height position and is in a second opening state. At this time, if the motor is stopped, the leakage stop valve 97 remains at the second height position. In this way, the leakage stop valve 97 can be set to have multiple different height positions and different opening states according to actual needs, so as to obtain multiple different tastes of coffee.

[0053] In some embodiments, as shown in Figure 1 、 Figure 4 、 Figure 7 and Figure 9 , the leakage stop valve lifting control mechanism further comprises a top rod 5 and a travel switch 6. The top rod 5 is vertically arranged, and a plurality of convex points are sequentially arranged along the length direction of the top rod 5.

[0054] As shown in Figure 10As shown, the rotating head 1 is also equipped with a spiral second slide rail 13. The lower end of the push rod 5 abuts against the spiral surface of the second slide rail 13. When the rotating head 1 rotates, the second slide rail 13 can push the push rod 5 to move up and down. When the push rod 5 moves up and down, multiple protrusions on the push rod 5 can trigger the limit switch 6 in sequence, so that the limit switch 6 generates different trigger signals. When different protrusions trigger the limit switch 6, the leak-proof bracket 3 pushes the leak-proof valve 97 to lift to the specified height position. The driving component 4 adopts a stepper motor. Both the stepper motor and the limit switch 6 are connected to the electronic board 72 inside the body 7 of the drip coffee machine. The electronic board 72 receives the trigger signal generated by the limit switch 6 and controls the stepper motor to stop. That is, when the rotating head 1 rotates to a predetermined angle under the drive of the stepper motor, the leak-stopping bracket 3 pushes the leak-stopping valve 97 to a predetermined height, and the push rod 5 also moves to a corresponding protrusion to trigger the limit switch 6. At this time, the electronic board 72 controls the stepper motor to stop. In this way, by adding the push rod 5 and the limit switch 6, the height position of the leak-stopping valve 97 can be further precisely controlled.

[0055] A drip coffee maker that can provide two different flavors of coffee generally meets the needs of most users. Therefore, the leak-proof valve 97 is set to have two height positions: a first height position and a second height position, both of which are open. The leak-proof valve 97 also has an initial position that is closed. The first height position is lower than the second height position, and the first height position is higher than the initial position. The second height position is the high position of the leak-proof valve 97, the first height position is the middle position, and the initial position is the low position.

[0056] To achieve control over the movement of the leak-proof valve 97 between low, middle, and high positions, such as... Figure 1 As shown, in this embodiment, the protrusions include a first protrusion 51, a second protrusion 52, and a third protrusion 53 arranged sequentially from top to bottom on the top rod 5. Figure 6 and Figure 7 As shown, when the rotating head 1 rotates to the first protrusion 51 and triggers the limit switch 6, the first end of the push rod 2 slides down from the first guide slope 121, and the leak-proof valve 97 is located at the lower part of the second guide slope 311 of the leak-proof bracket 3 (see...). Figure 5 The leak-proof valve 97 is in the low position and is closed (see...). Figure 13 and Figure 16 ).like Figure 9 As shown, when the rotating head 1 rotates to the second protrusion 52 and triggers the limit switch 6, the first end of the push rod 2 slides onto the middle of the first guide slope 121, and the leak-proof valve 97 is located at the middle of the second guide slope 311 of the leak-proof bracket 3 (see...). Figure 8 The leak-proof valve 97 is in the intermediate position and in the first open state (see...). Figure 14 andFigure 17 ). As Figure 3 and Figure 4 shown, when the rotating head 1 rotates to the third convex point 53 touching the stroke switch 6, the first end of the push rod 2 slides up the upper part of the first guide sliding slope 121, and the leak stop valve 97 is located on the upper part of the second guide sliding slope 311 of the leak stop bracket 3 or slides through the uppermost end of the second guide sliding slope 311 to the horizontal part (see Figure 2 ), the leak stop valve 97 is in the high position and in the second opening state (see Figure 15 and Figure 18 ). Wherein, the opening degree of the leak stop valve 97 in the first opening state when it is in the intermediate position is smaller than the opening degree of the leak stop valve 97 in the second opening state when it is in the high position. That is, the dripping speed of the leak stop valve 97 in the first opening state when it is in the intermediate position is smaller than the dripping speed of the leak stop valve 97 in the second opening state when it is in the high position, so that by lifting the leak stop valve 97 to the intermediate position or the high position at different heights respectively, the dripping speed of the coffee liquid can be controlled, thereby obtaining two different flavors of coffee.

[0057] In some embodiments, as Figure 10 shown, the rotating head 1 comprises a main body 11, and the side of the main body 11 towards the leak stop valve 97 has a vertically arranged disc-shaped surface. The first sliding rail 12 and the second sliding rail 13 are both arranged on the disc-shaped surface, and the first sliding rail 12 is arranged near the circumference of the disc-shaped surface and has a circular arc shape. The second sliding rail 13 is arranged near the center of the disc-shaped surface and gradually extends outward from the center of the disc-shaped surface in a spiral manner, so that the farther the position of the second sliding rail 13 is from the center of the disc-shaped surface, the larger the radius of the circle in which it is located is. And the closer the position of the second sliding rail 13 is to the center of the disc-shaped surface, the smaller the radius of the circle in which it is located is, so that when the rotating head 1 rotates, the second sliding rail 13 thereon can push the top rod 5 up and down through its spiral surface to make different convex points thereon touch the stroke switch 6 according to the lifting height of the top rod 5. It can be understood that the first sliding rail 12 is arranged around part of the circumference of the disc-shaped surface, not forming a complete ring, but a circular arc segment, so as to avoid blocking the lower end of the top rod 5 from acting on the second sliding rail 13; only the exposed spiral surface of the second sliding rail 13 can act on the top rod 5, and the first sliding rail 12 should avoid the exposed spiral surface, so that both sliding rails can realize their respective functions without interference from each other.

[0058] In some embodiments, as Figure 11 shown, the leak stop bracket 3 comprises two branch legs 31 arranged in a figure-eight shape, and the front ends of the two branch legs 31 are respectively formed with the second guide sliding slope 311. That is, the leak stop bracket 3 has a Y-shaped structure arranged horizontally. As Figure 12 shown, the leak stop valve 97 has sliding rods 971 protruding outward from opposite sides thereof, and the two sliding rods 971 are respectively arranged on the second guide sliding slope 311 of the two branch legs 31 and can slide up or down along the second guide sliding slope 311 when the leak stop bracket 3 is pushed by the rotating head 1, see Figure 2 ,Figure 5 and Figure 8 .

[0059] As shown in Figures 16 to 18 , the leakage stop valve 97 is provided with a reset component 972, which is used to apply a force to the leakage stop valve 97 to make it move downward, so that when the rotating head 1 rotates to the push rod 2 slides off the first guide slide slope 121 to cancel the pushing effect on the leakage stop bracket 3, the reset component 972 can push the leakage stop valve 97 to move downward to the low position and close. Since the push rod 2 no longer pushes the leakage stop bracket 3, when the leakage stop valve 97 moves downward, the leakage stop valve 97 also pushes the leakage stop bracket 3 to move in the direction away from the leakage stop valve 97 and reset to the initial position. The reset component 972 can be a spring.

[0060] The leakage stop valve lifting control mechanism of the embodiment of the present application can automatically control the lifting of the leakage stop valve 97, realize the switching of its opening and closing state, and does not need to use the top of a coffee cup or a coffee pot to lift the leakage stop valve 97 to open it, so it can adapt to containers of different heights. Moreover, the leakage stop valve 97 can be lifted to different height positions, so that the leakage stop valve 97 has different opening degrees to make coffee liquid of different tastes, meeting the needs of users for coffee of different tastes.

[0061] As shown in Figures 13 to 15 , the embodiment of the present application also provides a drip coffee machine, which includes a machine body 7, a top cover assembly 8 arranged on the machine body 7, and a funnel assembly arranged on the top cover assembly 8. The drip coffee machine also includes the leakage stop valve lifting control mechanism in any of the above embodiments, which is arranged on the funnel assembly and is used to drive the leakage stop valve 97 on the funnel assembly to lift to change the opening degree of the leakage stop valve 97.

[0062] The drip coffee machine of the embodiment of the present application can realize the automatic lifting of the leakage stop valve 97 due to the leakage stop valve lifting control mechanism, and does not need to use a cup (container) of a specific height to lift the leakage stop valve 97 to open it, so it can adapt to cups of different heights. Moreover, the lifting height of the leakage stop valve 97 has at least two gears: the middle gear and the high gear, which can realize the making of at least two kinds of coffee of different tastes.

[0063] The funnel assembly includes a funnel bracket and a funnel detachably arranged on the funnel bracket, and a filter screen 98 is arranged in the funnel. As shown in Figures 16 to 18 , and in cooperation with Figure 19 , the top of the funnel is provided with a top rod slot 911. The funnel bracket is provided with a top rod hole 922 opposite to the top rod slot 911. When the rotating head 1 rotates to the push rod 2 is in the middle gear or the high gear, the upper end of the top rod 5 penetrates into the top rod slot 911 through the top rod hole 922 to lock the funnel on the funnel bracket, as shown in Figure 17 andFigure 18 When the rotating head 1 rotates to the position that the push rod 2 releases the pushing of the leakage stopper 3, the upper end of the jacking rod 5 is out of the jacking rod slot 911 and the jacking rod hole 922, so as to release the locking of the hopper and the hopper support, see Figure 16 The hopper can be removed from the hopper support for cleaning and other operations.

[0064] When the rotating head 1 rotates to the position that the push rod 2 releases the pushing of the leakage stopper 3, the upper end of the jacking rod 5 is out of the jacking rod slot 911 and the jacking rod hole 922, so as to release the locking of the hopper and the hopper support, see

[0065] It can be understood that the jacking rod slot 911 on the hopper has a certain depth, and the upper end of the jacking rod 5 is located in the jacking rod slot 911 when the leakage stopper 97 is in the intermediate position and the high position, but only when the leakage stopper 97 is in the intermediate position, the depth of the upper end of the jacking rod 5 extending into the jacking rod slot 911 is not as deep as that when the leakage stopper 97 is in the high position.

[0066] The leakage stopper lifting control mechanism can not only control the lifting of the leakage stopper 97 to realize the opening and closing and the adjustment of the opening degree, but also can realize the locking and unlocking of the hopper on the hopper support, which is ingenious in structure design and convenient to use.

[0067] As shown in Figure 19 , the hopper support is roughly in the shape of an arc plate and is matched with the hopper having a cylindrical surface. The top of the hopper support extends to the side to form a mounting plane, and the jacking rod hole 922 is arranged on the mounting plane. The upper end of the jacking rod 5 can extend out of the jacking rod hole 922. The top periphery of the hopper is arranged on the mounting plane, and the jacking rod slot 911 is opposite to the jacking rod hole 922. When the jacking rod 5 moves upward, the upper end thereof can extend into the jacking rod slot 911 to lock the hopper on the hopper support.

[0068] Continuing to combine Figure 19 , the hopper assembly further comprises a hopper support seat 93 arranged at the rear side of the hopper support and fixedly connected therewith, and surrounding a cavity for accommodating the driving component 4, the rotating head 1, the push rod 2 and the jacking rod 5. As shown in Figure 20As shown, the funnel support is provided with a push rod hole 923 for the push rod 2 to pass through. The push rod hole 923 is not only used for guiding the movement of the push rod 2, but also used for limiting the push rod 2, so that both ends of the push rod 2 remain opposite to the rotating head 1 and the leak stop support 3. In addition, a top rod support 94 is fixed in the chamber, which is used for guiding and limiting the movement of the top rod 5, so as to ensure that the top rod 5 rises and falls along the predetermined track. The top rod 5 is also provided with a spring 54 for exerting downward movement to reset.

[0069] As shown in the drawings, Figure 19 The top cover assembly 8 includes a top cover 81 and a bottom cover 82, the top cover 81 is located above the bottom cover 82 and is buckled on the bottom cover 82 to form a containing cavity with the bottom cover 82. A water supply system is arranged in the containing cavity, one end of the water supply system is used for connecting with the water tank in the machine body 7. The side of the bottom cover 82 away from the top cover 81, that is, the lower side of the bottom cover 82 is provided with a shower head 83, the shower head 83 is connected with the other end of the water supply system, so that the water in the water tank is uniformly sprayed on the coffee powder in the filter screen 98 through the shower head 83 to brew the coffee powder.

[0070] The funnel assembly also includes a funnel top cover 95 and a funnel bottom cover 96, the funnel top cover 95 is arranged on the lower side of the bottom cover 82 and has a through hole 951 for avoiding the shower head 83. The top of the funnel support is fixed with the funnel top cover 95. When the funnel is locked on the funnel support, the funnel top cover 95 covers the top opening of the funnel, so that the funnel is combined with the funnel top cover 95. The funnel bottom cover 96 is arranged on the bottom of the funnel, and the funnel bottom cover 96 is provided with a through hole 961 for avoiding the leak stop valve 97.
