Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, specifically to a coffee machine that can be automatically raised and lowered. Background Technology

[0002] Coffee machines generally consist of two parts: a base and a brewing basket. The brewing basket is located on top of the base, and the coffee dispensing spout is located at the bottom of the basket. Currently, the brewing basket of coffee machines on the market is fixedly connected to the base, which means that the height of the brewing basket cannot be adjusted, thus limiting the height of the coffee cup placed on the base.

[0003] To achieve height adjustment of the brewing basket, related technologies employ a lifting structure between the brewing basket and the base. For example, invention patent CN115568758A discloses a lifting coffee machine, including a base and a brewing basket placed above the base. A manual lifting structure is provided between the brewing basket and the base, which is used to drive the brewing basket to rise and fall relative to the base. This prior art achieves the raising, lowering, and locking of the brewing basket through manual operation, which is very inconvenient and results in a poor user experience.

[0004] Therefore, there is still room for improvement and development in existing technologies. Utility Model Content

[0005] To address the problems of existing technologies, this utility model provides an automatically lifting coffee machine. By setting an automatic lifting mechanism between the brewing basket and the base, the brewing basket can be automatically raised and lowered, making it more convenient to use and providing a better user experience.

[0006] To achieve the above objectives, the technical solution applied in this utility model is as follows:

[0007] A coffee machine includes a base and a brewing basket, the brewing basket being movably positioned above the base. An automatic lifting mechanism is provided between the brewing basket and the base, the automatic lifting mechanism being used to drive the brewing basket to automatically rise and fall relative to the base. This configuration, by providing an automatic lifting mechanism between the brewing basket and the base, enables automatic raising and lowering of the brewing basket. Using an automatic lifting mechanism instead of a manual lifting structure makes it more convenient to use and provides a better user experience.

[0008] According to the above scheme, a sleeve is fixed on the base, and a lifting component is slidably provided inside the sleeve. The brewing basket is detachably installed on the lifting component. An automatic lifting mechanism is located between the sleeve and the lifting component. The automatic lifting mechanism is used to drive the lifting component to slide up and down relative to the sleeve, so that the lifting component drives the brewing basket to move up and down relative to the base.

[0009] According to the above scheme, the automatic lifting mechanism includes a gear rail fixed to the sleeve and a drive assembly fixed to the lifting component. The drive assembly includes a gear and a motor. The motor is mounted on the lifting component through a fixed cover, and the gear is mounted on the output end of the motor. The gear meshes with the gear rail. With this configuration, when the motor is working, it drives the gear to rotate. Since the gear meshes with the gear rail, the gear drives the lifting component to slide up and down relative to the sleeve during rotation.

[0010] According to the above scheme, a guide hole is formed inside the sleeve, and the lifting component includes a guide sleeve and a limiting seat connected to each other. The guide sleeve is slidably disposed in the guide hole of the sleeve, and the brewing basket is detachably installed in the limiting seat. A stroke sensing component is provided between the guide sleeve and the sleeve. With this configuration, the lifting component can be vertically and stably raised and lowered relative to the sleeve by the cooperation of the guide sleeve and the guide hole of the sleeve.

[0011] According to the above scheme, the travel sensing component includes a magnet mounted on the guide sleeve and a magnetic switch mounted on the sleeve. The magnetic switch has high-position sensing points, middle-position sensing points, and low-position sensing points spaced apart and corresponding to the magnet. This configuration allows for the following: when the magnet corresponds to the high-position sensing point, the distance between the brewing basket and the base is at its maximum, allowing for the use of a large-capacity tall cup on the base; when the magnet corresponds to the middle-position sensing point, a medium-sized cup can be used on the base; and when the magnet corresponds to the low-position sensing point, a small-capacity cup can be used on the base. Different cup capacities can be switched depending on the position.

[0012] According to the above scheme, the bottom of the brewing basket is provided with a liquid outlet hole 1, and a valve assembly for sealing the liquid outlet hole 1 is provided inside the liquid outlet hole 1. A bottom cover is fixed on the limiting seat, and a control component is provided on the bottom cover. The control component is correspondingly set with the valve assembly, and the control component is used to control the valve assembly to open the liquid outlet hole 1. With this configuration, in the initial state, under the action of the valve assembly, the brewed coffee in the brewing basket cannot flow out of the liquid outlet hole 1. When the brewing basket is assembled on the limiting seat, the control component on the bottom cover is correspondingly set with the valve assembly, and the control component can control the valve assembly to open the liquid outlet hole 1.

[0013] According to the above scheme, the valve assembly includes a sealing ring, a spring, and a leak-proof valve. The leak-proof valve has a column that passes through the first outlet hole and is fixedly connected to the sealing ring, which seals the outlet hole. The spring is sleeved on the column, with its two ends abutting against the leak-proof valve and the brewing basket, respectively. The control component is correspondingly positioned to the leak-proof valve. In this configuration, initially, the spring's elasticity causes the sealing ring to seal the first outlet hole. When the brewing basket is mounted on the limit seat, the control component on the bottom cover, corresponding to the leak-proof valve, allows the control component to activate the leak-proof valve and open the first outlet hole.

[0014] According to the above scheme, the leak-proof valve is provided with a support rod, and the control component includes a rocker plate and a control rod. The rocker plate is hinged to the inner wall of the bottom cover by a rotating shaft. The first end of the rocker plate is formed with a limiting groove that cooperates with the support rod, and the second end of the rocker plate is formed with a rocking part. The first end of the control rod is formed with a handle, and the second end of the control rod is formed with a control part. The control part passes through the bottom cover and is set to correspond with the rocking part. The outer wall of the control part is formed with a leak-proof part and multiple gear parts. With this setup, in the initial state, the sealing ring blocks the first outlet hole. At this time, the leak-proof part of the control unit corresponds to the rocker part. By rotating the handle of the control lever, the gear part of the control unit applies downward pressure to the rocker part, causing the first end of the rocker plate to rock upward. This, in turn, causes the limit groove to move the leak-proof valve upward, as well as the column and sealing ring upward, opening the first outlet hole. The spring is in a compressed state. When the rotation is adjusted so that the leak-proof part and the rocker part are aligned again, the leak-proof valve resets under the action of the spring, and the sealing ring re-blocks the first outlet hole. By rotating to different gears, the size of the first outlet hole can be easily controlled, thereby controlling the flow rate.

[0015] According to the above scheme, the bottom cover is provided with a second liquid outlet, and a leak-proof valve is correspondingly used to seal the second liquid outlet. With this configuration, when the brewing basket is assembled on the limiting seat, the leak-proof valve and the second liquid outlet are correspondingly sealed. When the leak-proof valve is controlled to open the first liquid outlet by the sealing ring, the second liquid outlet is simultaneously opened by the leak-proof valve. The coffee liquid in the brewing basket flows out into the cup assembly after passing through the first and second liquid outlets. That is, when the sealing ring blocks the first liquid outlet, the leak-proof valve blocks the second liquid outlet; when the sealing ring opens the first liquid outlet, the leak-proof valve opens the second liquid outlet.

[0016] According to the above design, it also includes a cup assembly and a water tank, which are detachably mounted on the base. The base has a placement slot that cooperates with and limits the cup assembly, located below the brewing basket. This design allows for the use of cups of different capacities depending on the distance between the brewing basket and the placement slot, making it convenient to use.

[0017] The beneficial effects of this utility model are:

[0018] This invention features an automatic lifting mechanism between the brewing basket and the base, enabling automatic raising and lowering of the brewing basket. By replacing the manual lifting structure with an automatic lifting mechanism, it becomes more convenient to use and provides a better user experience. Attached Figure Description

[0033] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0034] like Figures 1 to 12As shown, the coffee machine of this utility model includes a base 10 and a brewing basket 1. The brewing basket 1 is movably located above the base 10. An automatic lifting mechanism is provided between the brewing basket 1 and the base 10. The automatic lifting mechanism is used to drive the brewing basket 1 to automatically rise and fall relative to the base 10. This configuration, by providing an automatic lifting mechanism between the brewing basket 1 and the base 10, enables automatic raising and lowering of the brewing basket 1. Using an automatic lifting mechanism instead of a manual lifting structure makes it more convenient to use and provides a better user experience.

[0035] Furthermore, a sleeve 101 is fixed on the base 10, and a lifting member 8 is slidably provided inside the sleeve 101. The brewing basket 1 is detachably installed on the lifting member 8. An automatic lifting mechanism is located between the sleeve 101 and the lifting member 8. The automatic lifting mechanism is used to drive the lifting member 8 to slide up and down relative to the sleeve 101, so that the lifting member 8 drives the brewing basket 1 to move up and down relative to the base 10.

[0036] Furthermore, the automatic lifting mechanism includes a gear rail 102 fixed to the sleeve 101 and a drive assembly fixed to the lifting member 8. The drive assembly includes a gear 12 and a motor 13. The motor 13 is mounted on the lifting member 8 via a fixing cover 11, and the gear 12 is mounted at the output end of the motor 13. The gear 12 meshes with the gear rail 102. With this configuration, when the motor 13 operates, it drives the gear 12 to rotate. Because the gear 12 meshes with the gear rail 102, the gear 12, during its rotation, causes the lifting member 8 to slide up and down relative to the sleeve 101. Of course, the positions of the gear rail 102 and the drive assembly can be interchanged to achieve the same purpose.

[0037] In practical applications, the motor 13 has a self-locking function, which is used for positioning after lifting to a certain position. Existing technologies include stepper motors and servo motors with built-in self-locking functions. Many companies also combine the motor and brake into one unit to achieve the self-locking function, which is a relatively common technical solution.

[0038] Furthermore, the sleeve 101 has a guide hole 104 formed inside, and the lifting component 8 includes a guide sleeve 81 and a limiting seat 82 connected to each other. The guide sleeve 81 is slidably disposed in the guide hole 104 of the sleeve 101, and the brewing basket 1 is detachably installed in the limiting seat 82. A stroke sensing component is provided between the guide sleeve 81 and the sleeve 101. With this configuration, the lifting component 8 can be vertically and stably raised and lowered relative to the sleeve 101 by the cooperation of the guide sleeve 81 and the guide hole of the sleeve 101.

[0039] In practical applications, the guide sleeve 81 is preferably an L-shaped structure, with its lower end slidingly engaged with the sleeve 101 and its upper end bent and assembled with the brewing basket 1, so that the brewing basket 1 can correspond to the cup assembly 9 assembled on the base 10.

[0040] Furthermore, the travel sensing component includes a magnet 14 mounted on the guide sleeve 81 and a magnetic switch 15 mounted on the sleeve 101. The magnetic switch 15 has high-position sensing points 151, middle-position sensing points 152, and low-position sensing points 153, which are spaced apart and correspond to the magnet 14. Of course, the positions of the magnet 14 and the magnetic switch 15 can be interchanged; that is, the magnet 14 can be mounted on the sleeve 101, and the magnetic switch 15 on the guide sleeve 81. With this configuration, when the magnet 14 corresponds to the high-position sensing point 151, the distance between the brewing basket 1 and the base 10 is at its maximum, allowing a large-capacity tall cup 91 to be mounted on the base 10; when the magnet 14 corresponds to the middle-position sensing point 152, a medium-sized cup 92 can be mounted on the base 10; and when the magnet 14 corresponds to the low-position sensing point 153, a small-capacity cup 93 can be mounted on the base 10. Different cup capacities can be switched depending on the position.

[0041] In practical applications, when the magnet 14 corresponds to the sensing point at different positions on the magnetic control switch 15, the magnetic control switch 15 controls the motor 13 to stop, thereby accurately positioning the distance between the brewing basket 1 and the base 10. At this time, the brewing basket 1 cannot be raised or lowered relative to the base 10. The distance between the brewing basket 1 and the base 10 makes it convenient to assemble cups of different capacities for use.

[0042] Furthermore, the bottom of the brewing basket 1 is provided with a liquid outlet hole 17, and a valve assembly for sealing the liquid outlet hole 17 is provided inside the liquid outlet hole 17. A bottom cover 7 is fixed on the limiting seat 82, and a control component is provided on the bottom cover 7. The control component is correspondingly set with the valve assembly, and the control component is used to control the valve assembly to open the liquid outlet hole 17. With this configuration, in the initial state, under the action of the valve assembly, the brewed coffee in the brewing basket 1 cannot flow out of the liquid outlet hole 17. When the brewing basket 1 is assembled on the limiting seat 82, the control component on the bottom cover 7 is correspondingly set with the valve assembly, and the control component can control the valve assembly to open the liquid outlet hole 17.

[0043] Furthermore, the valve assembly includes a sealing ring 2, a spring 3, and a leak-proof valve 4. The leak-proof valve 4 has a column 41 that passes through the outlet hole 17 and is fixedly connected to the sealing ring 2. The sealing ring 2 and the outlet hole 17 are correspondingly sealed. The spring 3 is sleeved on the column 41, with its two ends abutting against the leak-proof valve 4 and the brewing basket 1, respectively. The control component is correspondingly positioned to the leak-proof valve 4. In this configuration, initially, the spring 3's elasticity causes the sealing ring 2 to seal the outlet hole 17. When the brewing basket 1 is mounted on the limiting seat 82, the control component on the bottom cover 7, corresponding to the leak-proof valve 4, can control the leak-proof valve 4 to open the outlet hole 17.

[0044] Furthermore, the leak-proof valve 4 is provided with a support rod 43, and the control assembly includes a rocker plate 5 and a control rod 6. The rocker plate 5 is hinged to the inner wall of the bottom cover 7 via a pivot 52. The first end of the rocker plate 5 is formed with a limiting groove 51 that cooperates with the support rod 43, and the second end of the rocker plate 5 is formed with a rocking part 53. The first end of the control rod 6 is formed with a handle 63, and the second end of the control rod 6 is formed with a control part 64. The control part 64 passes through the bottom cover 7 and is correspondingly set with the rocking part 53. The outer wall of the control part 64 is formed with a leak-proof part 61 and multiple gear parts 62. With this setup, in the initial state, the sealing ring 2 blocks the outlet hole 17. At this time, the leak-proof part 61 of the control unit 64 corresponds to the rocker part 53. By rotating the handle 63 of the control lever 6, the gear part 62 of the control unit 64 applies a downward pressure to the rocker part 53, causing the first end of the rocker plate 5 to rock upward. This causes the limiting groove 51 to move the leak-proof valve 4 upward, as well as the column 41 and the sealing ring 2 upward, opening the outlet hole 17. The spring 3 is in a compressed state. When the leak-proof part 61 and the rocker part 53 are rotated back to correspond, the leak-proof valve 4 resets under the action of the spring 3, and the sealing ring 2 re-blocks the outlet hole 17, making it easier to control the size of the outlet hole 17 and thus control the flow rate.

[0045] In practical applications, the control part 64 of the control lever 6 is pressed onto the tilting part 53. In the initial state, the leak-stopping part 61 corresponds to the tilting part 53, and the liquid outlet 17 is in a blocked state. When the control lever 6 is rotated, the tilting part 53 is applied to a different position according to the different gear parts 62 corresponding to the tilting part 53.

[0046] Furthermore, the bottom cover 7 is provided with a second outlet hole 71, and the leak-proof valve 4 is correspondingly sealed to the second outlet hole 71. With this configuration, when the brewing basket 1 is assembled on the limiting seat 82, the leak-proof valve 4 is correspondingly sealed to the second outlet hole 71. When the control of the leak-proof valve 4 drives the sealing ring 2 to open the first outlet hole 17, the second outlet hole 71 is simultaneously opened by the leak-proof valve 4. The coffee liquid in the brewing basket 1 flows out into the cup assembly 9 after passing through the first outlet hole 17 and the second outlet hole 71. That is, when the sealing ring 2 blocks the first outlet hole 17, the leak-proof valve 4 blocks the second outlet hole 71; when the sealing ring 2 opens the first outlet hole 17, the leak-proof valve 4 opens the second outlet hole 71.

[0047] In practical applications, a dual-outlet and dual-sealing structure is used to prevent coffee liquid from leaking out of the brewing basket 1, resulting in better leak prevention.

[0048] Furthermore, it also includes a cup assembly 9 and a water tank 16, which are detachably mounted on a base 10. The base 10 has a placement slot 103 that cooperates with and limits the cup assembly 9, and the placement slot 103 is located below the brewing basket 1. This arrangement allows for the use of cups of different capacities depending on the different distances between the brewing basket 1 and the placement slot 103, making it convenient to use.

[0049] In practical applications, the cup assembly 9 includes a tall cup 91, a medium cup 92, and a small cup 93.

[0050] The embodiments of the present utility model have been described above with reference to the accompanying drawings. However, the present utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present utility model without departing from the spirit and scope of the claims, and all of these forms are within the scope of protection of the present utility model.
