Description

Technical Field

[0001] This utility model relates to the field of wine extractors, and in particular to an electric wine extractor. Background Technology

[0002] With technological advancements and improved living standards, electric wine extractors have gradually entered the market. These extractors typically have a built-in miniature motor that drives a pump to automatically extract wine. Compared to traditional manual methods, electric wine extractors offer significant improvements in convenience and accuracy. They can easily handle containers of varying sizes, from small wine bottles to large wine barrels, efficiently extracting wine and greatly reducing the user's workload. Some electric wine extractors are also equipped with electronic control systems, allowing for precise setting of the amount of wine extracted to meet specific needs in different scenarios.

[0003] However, most existing electric wine extractors have fixed speed settings, with different speeds extracting corresponding volumes of wine, making precise metering impossible. Furthermore, the speed adjustment buttons use either mechanical or touch switches. Mechanical switches offer a poor tactile experience, while touch switches are prone to accidental activation. Since the extractor comes into contact with liquid, water stains easily accumulate around the touch switch. When water is present, the touch switch will automatically activate, potentially causing it to continuously trigger and malfunction, rendering the extractor unusable and inconvenient for users. Utility Model Content

[0004] The main purpose of this invention is to provide an electric wine extractor, which aims to solve existing technical problems.

[0005] To achieve the above objectives, this utility model proposes an electric wine extractor, comprising a housing, a wine extraction device disposed within the housing, and a main control circuit board. The wine extraction device includes a rotating metering component and a wine extraction component. The rotating metering component is disposed at one end of the housing and electrically connected to the main control circuit board for metering. The wine extraction component is disposed inside the housing. One end of the housing has a water inlet, and one side of the housing has a water outlet. The wine extraction component has an inlet for introducing wine and an outlet for discharging wine. The water inlet is connected to the inlet, and the outlet is connected to the outlet.

[0006] By adopting a knob-based metering component design, the knob-based metering component can be steplessly adjusted for precise metering. Then, the preset amount of wine is extracted through a wine extraction device, accurately obtaining the preset amount of wine, and avoiding the problems of accidental touch and misjudgment that are common with touch switches.

[0007] Preferably, the rotary metering component includes a knob, a gear, and an encoder. The knob is mounted on the top of the housing, the gear is connected to the gear transmission, the encoder is fixedly mounted inside the housing, one end of the gear shaft is fixedly connected to the rotor of the encoder, and the encoder is electrically connected to the main control circuit board.

[0008] The knob drives the gear to rotate, which in turn drives the encoder rotor to rotate, so that the encoder can calculate the precise angle of the knob's rotation and thus determine the volume of beverage to be dispensed.

[0009] Preferably, the top of the housing is provided with a display touch screen.

[0010] The touchscreen display allows users to set the desired amount of beverage to be dispensed, as well as other operational settings.

[0012] Preferably, an air pump is also provided on one side of the water pump, and the air outlet of the air pump is connected to the wine outlet.

[0013] The air pump inflates the water pipe while the wine is being drawn, allowing it to breathe quickly without the need for a long waiting time as with traditional decanting methods.

[0014] Preferably, the housing is provided with a trigger switch below the water outlet. The trigger switch includes a pulling part, a rotating part, and a pressing part. The rotating part is rotatably connected to the housing so that one end of the trigger switch is close to or away from the side wall of the housing. The housing is equipped with a micro switch for controlling the alcohol extraction in the rotation direction of the pressing part. The micro switch is electrically connected to the main control circuit board. When the pulling end is close to the side wall of the housing, the pressing part presses the micro switch to extract alcohol.

[0016] Preferably, the pressing part is provided with a first magnetic suction member, and a Hall sensor is provided below the micro switch. The Hall sensor is electrically connected to the main control circuit board. When the first magnetic suction member approaches the Hall sensor, the main control circuit board controls the wine extractor to turn on.

[0017] The device automatically turns on when the pressing part is rotated near the micro switch, and automatically turns off when a magnetic component moves away from the Hall sensor.

[0018] Preferably, the upper end of the latching part is provided with a groove for covering the water outlet, and the outer shell is provided with a second magnetic suction member below the pressing part. When the latching part is rotated to the water outlet, the first magnetic suction member and the second magnetic suction member attract and abut against each other.

[0019] By setting a groove at the upper end of the latching part to form a protective cover, when the latching part is rotated to the water outlet, the latching part covers the water outlet to prevent dust from entering. At the same time, the second magnetic component fixes the first magnetic component, further securing the trigger switch.

[0020] Preferably, the outer casing has a bottle mouth adapter adapted to the wine bottle at one end of the water outlet, and the bottle mouth adapter is detachably connected to the outer casing.

[0034] This utility model proposes an electric wine extractor.

[0035] like Figure 1As shown in one embodiment of this utility model, an electric wine extractor includes a housing 1, a wine extraction device disposed within the housing 1, and a main control circuit board. The wine extraction device includes a rotary metering component 2 and a wine extraction component 3. The rotary metering component 2 is located at one end of the housing 1 and electrically connected to the main control circuit board for setting the amount of wine extracted. The wine extraction component 3 is located inside the housing 1. One end of the housing 1 has a water inlet 5, and one side of the housing 1 has a water outlet 6. The wine extraction component 3 has an inlet for introducing wine and an outlet for discharging wine. The water inlet 5 is connected to the inlet, and the water outlet 6 is connected to the outlet. By adopting a rotary metering component design, the rotary metering component 21 can be steplessly adjusted for precise metering. The wine extraction device then extracts the preset amount of wine, accurately obtaining the preset amount of wine and avoiding the problems of accidental touch and misjudgment associated with touch switches.

[0036] Furthermore, an electric wine extractor includes a housing 1, a wine extraction device, and a main control circuit board. The housing 1 is made of food-grade ABS material and has an internal cavity for the wine extraction device. The wine extraction device consists of a rotary metering component 2 and a wine extraction component 3. The rotary metering component 2 is located on the top of the housing 1 and is used to set the wine extraction volume by rotating a knob 21. The wine extraction component 3 is located inside the housing 1 and includes a water pump 31 and an air pump 32. The inlet of the water pump 31 is connected to the water inlet 5 at the bottom of the housing 1 via a silicone hose, and the outlet is connected to the outlet 6. The outlet of the air pump 32 is connected to the outlet pipeline via a three-way valve for aerating the wine. The main control circuit board integrates an MCU controller, a power management module, and a drive circuit, and is electrically connected to the rotary metering component 2 and the wine extraction component 3 to achieve intelligent control of the wine extraction volume. A trigger switch 7 is located below the outlet 6. Working principle: After the user rotates the knob 21 to set the amount of wine to be drawn, presses the trigger switch 7 to start the water pump 31. The wine is drawn in from the water inlet 5 and discharged into the wine glass through the water outlet 6. When decanting is required, the air pump 32 is started to pump air into the drawn wine for full decanting.

[0037] like Figure 2 As shown, the rotary dispensing component 2 includes a knob 21, a gear 22, and an encoder 23. The knob 21 is mounted on the top of the housing 1. The gears 22 are connected to each other via a transmission mechanism. The encoder 23 is fixedly installed inside the housing 1. One end of the shaft of the gear 22 is fixedly connected to the rotor of the encoder 23. The encoder 23 is electrically connected to the main control circuit board. The knob 21 drives the gear 22 to rotate, which in turn drives the rotor of the encoder 23 to rotate. This allows the encoder 23 to calculate the precise angle of rotation of the knob 21, thereby determining the required volume of liquor to be dispensed. The rotation of the knob 21 converts the mechanical motion into an electrical signal through the encoder 23 (e.g., a rotary encoder 23), which is then transmitted to the microcontroller (MCU). The microcontroller calculates the set volume based on the received signal and displays the volume information on the display screen. Simultaneously, the microcontroller controls power devices such as relays or solid-state relays to achieve precise control of the dispensing volume.

[0038] Furthermore, the rotary metering component 2 includes a knob 21, a gear set 22, and an encoder 23. The knob 21 is an annular knob with an anti-slip texture design on the outer side and serrations on the inner circumference. It is connected to the gear 22 through the serrations. The knob 21 is sleeved on the top of the housing 1. The rotating shaft at the lower end of the gear 22 is fixedly connected to the rotor of the encoder 23 to convert the large-amplitude rotation of the knob 21 into a high-precision signal from the encoder 23. A fixing plate is provided inside the housing 1, and the encoder 23 is fixed on the fixing plate. The encoder 23 is a magnetic rotary encoder, and its rotor is coaxially connected to the gear 22. When the knob 21 rotates, the encoder 23 converts the angle signal into a pulse signal and transmits it to the main control circuit board. The MCU calculates the amount of alcohol drawn based on the number of pulses (for example, 10 pulses correspond to 1 ml).

[0039] Optionally, gear set 22 can be replaced with multi-stage reduction gear 22 to improve setting accuracy; encoder 23 can also be a photoelectric encoder 23, which detects the rotation angle through a grating disk.

[0040] Optionally, the rotating dispensing component 2 includes: a knob 21 cap, which can be located on the top or side of the outer casing 1, and its shape is not limited; a rotating shaft, which connects to the knob 21 cap and extends into the interior of the bottle dispenser, and the rotation of the knob 21 cap is transmitted to the internal mechanism through the rotating shaft. The rotating shaft is generally made of metal, such as stainless steel, and its connection with the knob 21 cap is usually a tight fit or fixed by a snap-fit ​​to ensure that the two rotate synchronously; a dial, which surrounds the knob 21 cap or is coaxial with the knob 21, and is marked with a capacity scale to indicate the currently set time. It can be backlit for easy reading of the set time in different lighting conditions; and a gear 22 transmission mechanism, which is located inside the bottle dispenser, where the rotating shaft is connected to a series of gears 22 to form the gear 22 transmission mechanism. The function of these gears 22 is to convert the rotational motion of the knob 21 into precise displacement or angular changes to achieve accurate time setting. The gears 22 are generally made of plastic or metal, and gears 22 of different sizes and numbers of teeth mesh with each other according to the requirements of the transmission ratio. The timer assembly is the core control component of the timer knob 21, mainly composed of a mainspring, an escapement mechanism, a gear train 22, and a cam. When the knob 21 rotates, the mainspring is wound through the gear train 22. The mainspring releases its elastic potential energy, driving the escapement mechanism to swing regularly, which in turn drives the gear train 22 to rotate slowly. Different gears 22 are connected to the cam through a specific transmission ratio. The rotation of the cam controls the on / off of the internal circuit of the wine extractor. When the set time ends, the position change of the cam triggers the micro switch 74, cutting off the working circuit of the wine extractor and stopping the wine extraction. To prevent damage from excessive rotation of knob 21, a limiting structure is typically installed. This limiting structure can be a limiting protrusion on the rotation axis of knob 21, which engages with a limiting groove on a fixed component inside the wine dispenser. When knob 21 rotates to a certain angle, the limiting protrusion contacts the limiting groove, preventing knob 21 from continuing to rotate. A return spring is used to automatically return knob 21 to its initial position after the timing cycle ends. The return spring is fitted onto the rotation axis, with one end fixed to knob 21 and the other end fixed to a fixed bracket inside the wine dispenser. When the spring has released all its energy, the spring force causes knob 21 to rotate in the opposite direction, returning to its initial position, preparing for the next timing operation.

[0041] Preferably, the top of the housing 1 is provided with a display touch screen 8, through which the quantitative value of the wine to be drawn, as well as other operation settings, can be set.

[0042] Optionally, the touchscreen 8 can be configured to function as follows: Clicking the "A" button illuminates the small "A" icon on the right side of the digital display, indicating that the aeration function is on. During wine extraction, the air pump 32 will inflate the water pipe for decanting, eliminating the need for the traditional half-hour decanting process. This is suitable for red wine, some whiskeys, and other wines that require decanting. Clicking the "A" button again turns off the small "A" icon on the right side of the digital display, indicating that the aeration function is off. Pressing and holding the "A" button for 2 seconds switches between measurement units: ml and oz.

[0043] Preferably, such as Figure 3 As shown, the wine extraction component 3 includes a water pump 31, which is electrically connected to the main control circuit board.

[0044] Water pump 31 can also be replaced by centrifugal pump / submersible pump 31 / self-priming pump / screw pump / piston pump.

[0045] Preferably, an air pump 32 is also provided on one side of the water pump 31. The air outlet of the air pump 32 is connected to the wine outlet. The air pump 32 can inflate the water pipe when the wine is being drawn, so that the wine can be aerated at the same time, without having to wait for a long time like the traditional wine aeration method.

[0046] Preferably, such as Figure 4 As shown, the outer casing 1 has a trigger switch 7 below the water outlet 6. The trigger switch 7 includes a pulling part 71, a rotating part 72, and a pressing part 73. The rotating part 72 has rotating shafts on opposite sides. The outer casing 1 has an opening below the water outlet 6. The two side walls of the opening have rotating grooves. The rotating shaft is installed in the rotating grooves, so that one end of the trigger switch 7 is close to or away from the side wall of the outer casing 1. The pressing part passes through the opening and is inserted into the interior of the outer casing 1. The outer casing 1 has a micro switch 74 for controlling the alcohol extraction installed on the rotation path of the pressing part 73. The micro switch 74 is electrically connected to the main control circuit board. When the pulling end is close to the side wall of the outer casing 1, the pressing part 73 presses the micro switch 74 to extract alcohol.

[0047] like Figure 5As shown, the trigger switch 7 includes a pulling part 71, a rotating shaft, and a pressing part 73. The rotating shaft is located in a shaft hole in the side wall of the housing 1. When the pulling part 71 is pressed down, it drives the pressing part 73 to trigger the micro switch 74. The pressing part 73 is embedded with a first magnet. A Hall sensor is provided at a corresponding position inside the housing 1. When the trigger moves close to the side wall of the housing 1 to a certain distance, the pressing part 73 can contact the switch of the micro switch 74, causing the pulling part 71 to naturally droop under the influence of gravity, thus tilting the pressing part 73 upwards. When the micro switch 74 is in contact but not triggered, the first magnet approaches the Hall sensor, triggering the power-on signal. When the trigger is pulled, the magnet moves away, the micro switch 74 is pressed, and the pumping starts. The upper end of the triggering part 71 is provided with a U-shaped groove 78. When the trigger is reset, the groove 78 covers the outlet 6 to prevent dust contamination. The outer casing 1 is provided with a second magnetic attractor 75 below the pressing part 73. When the triggering part 71 is rotated to the outlet 6, the first magnetic attractor 76 and the second magnetic attractor 75 attract and abut against each other.

[0048] A silicone sealing ring can be installed inside the groove 78 to enhance the dustproof effect.

[0049] Preferably, the pressing part 73 is provided with a first magnetic suction member 76, and a Hall sensor 77 is provided below the micro switch 74. The Hall sensor 77 is electrically connected to the main control circuit board. When the first magnetic suction member 76 is close to the Hall sensor 77, the main control circuit board controls the wine dispenser to turn on. When the pressing part 73 is rotated to the vicinity of the micro switch 74, it automatically turns on. When the magnetic suction member moves away from the Hall sensor 77, it automatically turns off.

[0050] Preferably, the upper end of the latching part 71 is provided with a groove 78 for covering the water outlet 6. By providing the groove 78 at the upper end of the latching part 71, a protective cover is formed. When the latching part 71 is rotated to the water outlet 6, the latching part 71 covers the water outlet 6 to prevent dust from entering. At the same time, the second magnetic suction member 75 fixes the first magnetic suction member 76, further fixing the trigger switch 7.

[0051] Preferably, the outer casing 1 has a bottle neck adapter 4 adapted to the wine bottle at one end of the outlet 6. The bottle neck adapter 4 is detachably connected to the outer casing 1, which can be by snap-fit, bolt connection, or direct plug-in fixation. Different sizes of bottle neck adapters 4 can be replaced to accommodate different bottle neck sizes.

[0052] Optionally, the main control circuit board integrates a low-power Bluetooth module, supporting connection to a mobile app. When the trigger switch 7 is magnetically activated to power on, the system wakes up from sleep mode; if there is no operation within 5 minutes, it automatically enters sleep mode to save power. The power supply uses a rechargeable lithium battery, and the touchscreen 50 displays real-time battery level and charging status.

[0053] Optionally, after the latching part 71 is latched, the first magnetic member 76 and the second magnetic member 75 disengage, and the latching part 71 falls under the action of gravity. At this time, the pressing part 73 rotates and tilts up to abut against the switch push plate of the micro switch 74. By the tilt angle of the switch push plate of the micro switch 74, the trigger switch 7, i.e. the latching part 71, is initially fixed at a position of 60-70 degrees. When it is necessary to take wine, the latching part 71 is pushed to 90 degrees, that is, aligned with the side of the outer casing 1. The pressing part 73 presses the button of the micro switch 74 to start the wine taking program.

[0054] Alternatively, by separately setting an elastic limit block, the pulling part 71 of the trigger switch 7 can be initially limited to a position that is 60-70 degrees from the side wall of the housing 1. If the pulling part 71 is pressed further, the elastic limit member will be squeezed and deformed, causing the pulling part 71 to move closer to the side wall of the housing 1, which will drive the pressing part 73 to trigger the micro switch 74.

[0055] Specifically, the working principle and usage process of this utility model are as follows: precise quantitative measurement is achieved by steplessly adjusting the quantitative component of knob 21, and then the preset amount of alcohol is extracted by the alcohol extraction device. This avoids the problems of accidental touch and misjudgment that are common with touch switches. In addition, the adjustment settings of knob 21 also have a certain mechanical sophistication, providing users with a good experience. The magnetic trigger and detachable adapter enhance the ease of use and are suitable for various scenarios such as home and bar.

[0056] Furthermore, the rotary encoder 23 further enables high-precision setting of the amount of alcohol drawn. The knob 21 drives the gear 22 to rotate, which in turn drives the rotor of the encoder 23 to rotate. The encoder 23 calculates the precise angle of rotation of the knob 21, thereby obtaining the required amount of alcohol to be drawn. The rotation of the knob 21 converts the mechanical motion into an electrical signal through the encoder 23, which is transmitted to the microcontroller (MCU). The microcontroller calculates the set amount based on the received signal and displays the amount of alcohol on the display screen. Then, the water pump 31 is used to draw the alcohol in a quantitative manner.

[0057] Wine extractor operation procedure: Rotate the trigger switch 7 downwards to open it. The switch will be initially fixed at a position of 60-70 degrees. At this time, the magnet on the trigger switch 7 is close to the Hall sensor 77, and the wine extractor will turn on automatically. Then rotate the knob 21. The knob 21 is linked to the gear 22, which drives the encoder 23 to rotate. Adjust different quantities as needed. The numbers on the touch screen 8 will change accordingly. Then press the trigger switch 7 to 90 degrees with the glass. The micro switch 74 is pressed and triggered. The wine extractor will automatically extract the corresponding quantity of wine and then stop automatically. Finally, remove the glass and release the trigger switch 7.

[0058] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
