Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of coffee, in particular to a coffee brewing device based on single motor driving and a coffee brewing machine. BACKGROUND

[0002] At present, with the rise of coffee culture, the production equipment in the coffee field is constantly updated and iterated, and the market demand is increasingly diversified. With people's pursuit of coffee quality, people also put forward higher requirements on the brewing method of the coffee machine. In order to make coffee drinks more conveniently, the hand-pouring coffee machine stands out in the market.

[0003] For example, Chinese patent document CN117958597A discloses a hand-pouring coffee machine, which comprises a rotating tank body, a water tank arranged on the rotating tank body, and a control device. The rotating tank body is provided with a water outlet nozzle with variable angle. The water outlet nozzle is communicated with the water tank through a water channel system. The rotating tank body is further provided with a driving device electrically connected with the control device, a transmission structure connected with the driving device, and a pushing member. The transmission structure and the pushing member are arranged above the water outlet nozzle. The driving device drives the transmission structure to push the pushing member to move up and down above the water outlet nozzle to change the inclination angle of the water outlet nozzle in the vertical direction.

[0004] However, the design of the above-mentioned hand-pouring coffee machine has the following problems:

[0005] Although the above-mentioned coffee machine changes the mode of the water outlet nozzle by connecting the transmission structure with the driving device, it is necessary to connect the driving device and the transmission structure with two motors respectively so that the driving device and the transmission structure are driven. Therefore, the pushing member pushes the water outlet nozzle to move up and down to change the vertical direction of the water outlet nozzle. However, the driving device and the transmission structure are connected by double motors. When any one of the motors fails, the entire hand-pouring coffee machine cannot work normally, thereby affecting the work efficiency and work flow. At the same time, the inclination angle of the water outlet nozzle is realized by using double motors. Because the double motors work simultaneously, the power consumption of the equipment operation is increased, thereby increasing the use cost of the equipment. Utility model content

[0030] For the purpose of promoting the understanding of the present disclosure, the present disclosure will be described in further detail below with reference to the attached drawings. The preferred embodiments of the present disclosure are shown in the drawings. However, the present disclosure can be realized in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present disclosure can be more thoroughly and completely understood.

[0031] It should be noted that when an element is referred to as being "on" another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present. The terms "vertical", "horizontal", "left", "right", and the like as used herein are for the purpose of illustration only and are not intended to limit the present disclosure.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The terminology used in the description of the disclosure herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0033] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure will be further described in detail below in combination with specific embodiments:

[0034] As Figures 1 to 3As shown, the single motor driven coffee brewing device 10 of one embodiment comprises a rotating tank body 100, a water delivery pipe 200, a driving motor 300, a deflection nozzle holder 400, a pushing power holder 500 and a pushing nut seat 600; the rotating tank body 100 is used to be rotatably installed on a coffee machine, two ends of the rotating tank body 100 are respectively provided with a water outlet 150 and a water inlet 140, one end of the water delivery pipe 200 is communicated with the water inlet 140, the driving motor 300 is used to be installed on the coffee machine, and a power shaft of the driving motor 300 is used to drive the rotating tank body 100 to rotate relative to the coffee machine.

[0035] In the embodiment, the rotating tank body 100 is formed with an inner cavity 110 and a position avoiding hole 120 in communication, the pushing power holder 500 is slidably arranged on an inner wall of the inner cavity 110, two ends of the pushing power holder 500 are respectively abutted against the pushing nut seat 600 and the deflection nozzle holder 400, the pushing nut seat 600 is located in the position avoiding hole 120, and the pushing nut seat 600 is formed with a threaded transmission hole 610 used to be threadedly connected with a threaded table of the coffee machine; the deflection nozzle holder 400 is rotatably arranged in the inner cavity 110, and the position of the deflection nozzle holder 400 abutting against the pushing power holder 500 deviates from a swing center line of the deflection nozzle holder 400; a water receiving end of the deflection nozzle holder 400 is communicated with the other end of the water delivery pipe 200, and a water outlet end of the deflection nozzle holder 400 is correspondingly arranged with the water outlet 150.

[0036] It can be understood that by driving the power shaft of the motor 300 to drive the rotating tank body 100 to rotate relative to the coffee machine, the rotating tank body 100 itself performs a rotational motion, and the nut seat 600 is located in the avoiding hole 120 of the rotating tank body 100. When the rotating tank body 100 rotates, the nut seat 600 will be driven by the threaded transmission hole 610 and the threaded transmission connection of the threaded table of the coffee machine, so that the nut seat 600 moves downward relative to the coffee machine in the inner cavity 110 of the rotating tank body 100. At the same time, because the two ends of the push power frame 500 abut against the nut seat 600 and the deflection nozzle frame 400 respectively, when the nut seat 600 moves downward, a downward thrust is generated to abut against the push power frame 500. Because one end of the push power frame 500 abuts against the deflection nozzle frame 400, the deflection nozzle frame 400 rotates in the inner cavity 110 of the rotating tank body 100, thereby making the deflection nozzle frame 400 deviate from the swing center line of the deflection nozzle frame 400. Because the water receiving end of the deflection nozzle frame 400 is connected to one end of the delivery pipe, and the water outlet end of the deflection nozzle frame 400 is correspondingly arranged, when the water source of the water delivery pipe 200 flows to the water receiving end of the deflection nozzle frame 400, the deflection nozzle frame 400 will be deflected in the inner cavity 110 of the rotating pipe body, so that the water outlet direction of the deflection nozzle frame 400 is changed. At the same time, because the rotating pipe body itself performs a circular rotational motion, and the deflection nozzle frame 400 performs a deflection motion in the inner cavity 110 of the rotating tank synchronously, a central, spiral and surrounding water outlet mode is realized. By driving the rotating tank body 100 with a single driving motor 300, and driving the deflection nozzle frame 400 by the nut seat 600 acting on the push power frame 500 to change the water outlet angle, the need for another driving motor 300 to change the water outlet angle of the deflection nozzle frame 400 is avoided, the operating power consumption of the equipment is reduced, and the use cost of the equipment is reduced. At the same time, by using a single motor, when any one motor fails, the brewing cannot be completed, thereby reducing the failure rate of the equipment.

[0037] In combination Figure 1 With Figure 2As shown, in one embodiment, the pushing power frame 500 has a limiting post 510 protruding on the side near the pushing nut seat 600, and the pushing nut seat 600 has a groove 620 on the side near the pushing power frame 500, with the limiting post 510 abutting against the groove 620. It is understood that a limiting post 510 protrudes from the side of the pushing power frame near the pushing nut seat 600, and a groove 620 is formed on the side of the pushing nut seat 600 near the pushing power frame 500. When the pushing nut seat 600 slides down towards the pushing power frame 500, the limiting post 510 will abut against the groove 620, so that the pushing nut seat 600 acts on the force point of the limiting post 510, providing pressure to drive the power output end of the pushing power frame 500 to the deflector nozzle frame 400, thereby causing the deflector nozzle frame 400 to be subjected to pressure and change the tilt angle of the deflector nozzle frame 400; and the distance between the groove 620 and the limiting post 510 is the maximum sliding distance of the pushing nut seat 600; the groove 620 is formed at the bottom of the pushing nut seat 600, and the area of ​​the groove 620 is larger than the area of ​​the top of the limiting post 510.

[0038] like Figure 1 As shown, the coffee brewing device further includes a shock-absorbing buffer 700. One end of the shock-absorbing buffer 700 is sleeved on the limiting post 510, and the other end of the shock-absorbing buffer 700 abuts against the groove 620. It can be understood that the shock-absorbing buffer 700, positioned within the groove 620 and sleeved on the limiting post 510, reduces vibration and noise generated when the push nut seat 600 moves at high speed within the groove 620. It also effectively protects the contact surface between the limiting post 510 and the groove 620. Furthermore, when the push nut seat 600 impacts the limiting post 510, the shock-absorbing buffer 700 absorbs the impact force, preventing a hard collision. When the drive motor 300 stops working, the shock-absorbing buffer 700 releases its elasticity, allowing the push nut seat 600 to smoothly return to its original position. The shock-absorbing buffer 700 here can be an elastic rubber spring or a compression spring.

[0039] Combination Figure 1 and Figure 2As shown, in one embodiment, the pushing power frame 500 includes a power frame body 520 and a pushing rod 530. One end of the pushing rod 530 is connected to the bottom wall of the power frame body 520, and the other end of the pushing rod 530 abuts against the end face of the deflecting nozzle frame 400. It can be understood that one end of the pushing rod 530 is welded to the bottom wall of the power frame body 520, and the other end of the pushing rod 530 abuts against the end face of the deflecting nozzle frame 400. When the pushing nut seat 600 slides downward, because the limiting post 510 is located in the inner cavity 110 of the power frame body 520, the groove 620 of the pushing nut seat 600 abuts against the limiting post 510 of the power frame body 520. This causes a pushing force to be applied, and the pushing rod 530 abuts against the end face of the deflecting nozzle frame 400, causing the deflecting nozzle frame 400 to rotate within the inner cavity 110 of the rotating tank body 100.

[0040] like Figure 1 As shown, in another embodiment, an elastic reset member 540 is provided between the pushing power frame 500 and the deflecting nozzle frame 400. One end of the elastic reset member 540 abuts against the bottom of the pushing power frame 500, and the other end abuts against the end face of the nozzle frame. It can be understood that by providing the elastic reset member 540 between the pushing power frame 500 and the deflecting nozzle frame 400, with one end abutting against the bottom of the pushing power frame 500 and the other end abutting against the end face of the nozzle frame, when the pushing power frame 500 releases pressure, the elastic reset member 540 will, due to its elasticity, allow the pushing power frame 500 to return to its initial position, thereby ensuring the precise angle reset of the deflecting nozzle frame 400, maintaining the stability and consistency of the water outlet 150, and improving the quality and taste of brewed coffee. The elastic reset member 540 here can be a compression spring or a coil spring.

[0041] Combination Figure 1 and Figure 2 As shown, in one embodiment, a sliding hole 5210 is provided on the outer periphery of the power frame body 520, and a guide post 130 protrudes from the side of the rotating tank body 100 near the pushing power frame 500. The guide post 130 passes through the sliding hole 5210 and is slidably connected to the pushing power frame 500. It can be understood that the sliding hole 5210 on the outer periphery of the pushing power frame 500 and the guide post 130 protruding from the rotating tank body allow the pushing power frame 500 to slide downwards when the drive motor 300 drives the rotating tank body 100 to rotate. This is because the guide post 130 is connected to the sliding hole 5210 of the pushing power frame 500, thereby causing the pushing power frame 500 to abut against the deflecting nozzle frame 400.

[0042] Combination Figure 1 andFigure 2 As shown in another embodiment, the inner circumferential wall of the power frame body 520 is provided with a limiting portion 5220, the outer periphery of the pushing nut seat 600 is provided with a limiting groove 630, and the limiting portion 5220 is arranged in the limiting groove 630. It can be understood that by arranging the limiting portion 5220 on the inner circumferential wall of the pushing power frame 500, and arranging the limiting groove 630 on the outer periphery of the pushing nut seat 600, and arranging the limiting portion 5220 in the limiting groove 630, when the pushing nut seat 600 seat slides down, the movement trajectory of the pushing nut seat 600 seat is more stable through the guidance of the limiting portion 5220 and the constraint of the limiting groove 630, which avoids the deviation of the pushing nut seat 600 seat from the descending trajectory due to shaking, thereby ensuring that the pushing nut seat 600 seat can accurately act on the pushing power frame 500, and through the cooperation of the limiting portion 5220 and the limiting groove 630, the pushing nut seat 600 can move downward relative to the pushing power frame 500, so that the pushing nut seat 600 can abut against the pushing power frame 500.

[0043] In combination Figure 1 With 2 As shown in one of the embodiments, the deflection nozzle frame 400 includes a nozzle frame body 410 and a rotating shaft 420, one end of the rotating shaft 420 is rotatably connected to the outer circumferential wall of the nozzle frame body 410, and the other end of the rotating shaft 420 is rotatably connected to the nozzle frame body 410. It can be understood that by rotatably connecting one end of the rotating shaft 420 to the outer circumferential wall of the nozzle frame body 410, and rotatably connecting the other end of the rotating shaft 420 to the nozzle frame body 410, a stable support structure is formed, which ensures that the nozzle frame remains balanced during deflection, avoids tilting or shaking due to uneven force, and further improves the stability of the deflection nozzle frame 400, so that the deflection nozzle frame 400 can be accurately deflected at a preset angle under the rotation of the rotating shaft 420 when the power output end of the pushing power frame 500 abuts against the deflection nozzle frame 400.

[0044] As Figure 1As shown, in another embodiment, the bottom of the water nozzle frame body 410 is provided with a balance adjusting member 4110, one end of the balance adjusting member 4110 is connected to the bottom of the water nozzle frame body 410, and the other end of the balance adjusting member 4110 is connected to the inner bottom wall of the rotating tank body 100. It can be understood that because one end of the balance adjusting member 4110 is connected to the bottom of the water nozzle frame body 410 and the other end is connected to the inner bottom wall of the rotating tank body 100, when the power output end of the pushing power frame 500 exerts a pushing force on the water nozzle frame body 410, the balance adjusting member 4110 can act as a stable fulcrum to effectively prevent excessive tilting caused by the moment generated by deflection, ensuring the stability of the water nozzle frame body 410 during deflection, and at the same time, the water nozzle frame body 410 absorbs the impact force generated by the deflection action under the support of the balance adjusting member 4110, further protecting the deflection water nozzle frame 400 from damage. The balance adjusting member 4110 here can be a rubber spring and a compression spring. When the balance adjusting member 4110 is arranged below the pushing rod 530, the balance adjusting member 4110 is in a compressed state, and when the pushing rod 530 is pressed down, the balance adjusting member 4110 will be compressed and deformed, and the water nozzle frame body 410 will rotate relative to the rotating shaft 420 to a predetermined angle. Conversely, when the pushing rod 530 is reset, the balance adjusting member 4110 will be elastically reset due to the release of pressure by the pushing rod 530, causing the water nozzle frame body 410 to reset. In another case, when the balance adjusting member 4110 is arranged on the other side of the water nozzle frame body 410 in a tension state, when the pushing rod 530 is pressed down, the balance adjusting member 4110 will be compressed and deformed, and the water nozzle frame body 410 will rotate relative to the rotating shaft 420 to a predetermined angle. Conversely, when the pushing rod 530 is reset, the balance adjusting member 4110 will generate a pulling force, causing the water nozzle frame body 410 to reset.

[0045] In combination Figure 1 With Figure 3 As shown, in one of the embodiments, the coffee brewing device further comprises a thrust bearing member 800, which is installed in the inner shell of the coffee machine, one end of the thrust bearing member 800 is arranged at the bottom of the rotating tank body 100, and the other end of the thrust bearing member 800 abuts against the inner bottom wall of the coffee machine. It can be understood that by installing the thrust bearing member 800 in the inner shell of the coffee machine, and arranging one end of the thrust bearing member 800 at the rotating tank body 100 and the other end of the thrust bearing member 800 abutting against the inner bottom wall of the coffee machine, the thrust bearing member 800 can act as an intermediate medium between the rotating tank body 100 and the inner shell of the coffee machine, avoiding direct contact between the rotating tank body 100 and the inner shell of the coffee machine due to rotation, reducing friction and wear, prolonging the service life of the device, and at the same time ensuring smooth rotation of the rotating tank body 100 and improving the uniformity and taste of coffee brewing.

[0046] In combination Figure 1 With Figure 3 As shown in one embodiment, the coffee brewing device further comprises a switch button 900 and a reset switch 100a, the reset switch 100a is arranged on the end face of the rotating tank body 100, and the trigger part of the reset switch 100a extends to the avoidance hole 120, the reset switch 100a is electrically connected to the driving motor 300, the switch button 900 is arranged in the avoidance hole 120, one end of the switch button 900 abuts against the push nut seat 600, and the other end of the switch button 900 abuts against the trigger part of the reset switch 100a. It can be understood that the reset switch 100a is arranged on the end face of the rotating tank body 100, the trigger part of the reset switch 100a extends to the avoidance hole 120, and the switch button 900 is located between the push nut seat 600 and the reset switch 100a. When the device completes brewing, the push nut seat 600 moves upward, so that the push nut seat 600 abuts against one side of the switch button 900, drives the switch button 900 to move upward and trigger the trigger part of the reset switch 100a, and the reset switch 100a is electrically connected to the driving motor 300, so that the reset switch 100a sends a signal to the driving motor 300. After the driving motor 300 receives the signal of the reset switch 100a, the driving motor 300 stops running, the device returns to the initial state, ensures the consistency and stability of each brewing process, and improves the user experience.

[0047] The application also provides a coffee brewing device, which comprises the single-motor-driven coffee brewing device 10 according to any one of the above embodiments. It can be understood that the rotating tank body 100 is driven by a single driving motor 300, and the push nut seat 600 acts on the push power frame 500 to drive the deflection nozzle frame 400 to change the water outlet angle, thereby avoiding the need for another driving motor 300 to change the water outlet angle of the deflection nozzle frame 400, reducing the operating power consumption of the device and reducing the use cost of the device. At the same time, the single-motor mode avoids the situation that when any one of the two double-motor devices fails, the brewing cannot be completed, thereby reducing the failure rate of the device.

[0048] Compared with the prior art, the present disclosure has at least the following advantages:

[0049] The rotation of the rotating tank body 100 relative to the coffee machine is driven by the power shaft of the driving motor 300, so that the rotating tank body 100 itself rotates and the nut seat 600 is located in the avoiding hole 120 of the rotating tank body 100. When the rotating tank body 100 rotates, the nut seat 600 will be driven downward in the inner cavity 110 of the rotating tank body 100 due to the threaded transmission hole 610 and the threaded transmission connection of the threaded table of the coffee machine, and at the same time, because the two ends of the push power frame 500 abut against the nut seat 600 and the deflection nozzle frame 400 respectively, when the nut seat 600 moves downward, a downward thrust is generated to abut against the push power frame 500, and because one end of the push power frame 500 abuts against the deflection nozzle frame 400, the deflection nozzle frame 400 rotates in the inner cavity 110 of the rotating tank body 100, so that the deflection nozzle frame 400 deviates from the swing center line of the deflection nozzle frame 400, and because the water receiving end of the deflection nozzle frame 400 is connected to one end of the conveying pipe, and the water outlet end of the deflection nozzle frame 400 is correspondingly arranged, when the water source of the water conveying pipe 200 flows to the water receiving end of the deflection nozzle frame 400, the water outlet direction of the deflection nozzle frame 400 is changed due to the central deflection movement of the deflection nozzle frame 400 in the inner cavity 110 of the rotating pipe body; at the same time, because the rotating pipe body itself rotates in a circular manner, and the deflection nozzle frame 400 synchronously deflects in the inner cavity 110 of the rotating tank, the central, spiral and surrounding water outlet modes are realized; the rotating tank body 100 is driven by a single driving motor 300, and the nut seat 600 acts on the push power frame 500 to drive the deflection nozzle frame 400 to change the water outlet angle, avoiding the need for another driving motor 300 to change the water outlet angle of the deflection nozzle frame 400, which can reduce the operating power consumption of the equipment and reduce the use cost of the equipment; at the same time, the single motor is adopted, avoiding the situation that when any one of the two double motors fails, the brewing cannot be completed, thereby reducing the failure rate of the equipment.

[0050] The above-described embodiments only express several embodiments of the present disclosure, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present disclosure, a number of modifications and improvements can be made, which belong to the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure patent should be subject to the appended claims.
