[0024] This utility model provides a steam milk frother with noise reduction function, including a frame 101, a faucet steam outlet 102, a lifting assembly, a steam assembly, and a noise reduction assembly. The noise reduction assembly includes a rotating motor 103, a cup holder 104, a soundproof cover 105, a photoelectric sensor 106, a rotating component, a positioning component, and an inner soundproof cover 122. The rotating component includes a bearing 107 and a synchronous pulley 108. The positioning component includes a magnetic Hall switch 109 and a magnet 110. The lifting assembly includes a drive motor 111, a ball screw 112, a slider 113, and a limit photoelectric sensor 114. The steam assembly includes an inner tank 115, a water pump 116, a water inlet solenoid valve 117, a one-way valve 118, and a heating component. The heating component includes a heating tube 120 and a water level probe 121. This solution solves the noise generated by air vibration during the heating process in existing steam milk frothers. It is understood that this solution can be used to reduce the noise generated by steam milk frothers during the heating process.

[0025] In this embodiment, the lifting assembly can drive the faucet steam outlet rod 102 to move up and down, and cooperate with the steam assembly to steam the beverage in the mug on the cup holder 104.

[0026] The rotating motor 103 is fixedly connected to the frame 101 and located on one side of the frame 101. The cup holder 104 is connected to the frame 101 and the rotating motor 103 respectively through the rotating component and is located on the side of the frame 101 near the rotating motor 103. The soundproof cover 105 is fixedly connected to the cup holder 104 and is located on the side of the cup holder 104 near the frame 101. The photoelectric sensor 106 is disposed on the frame 101 and is located on the side of the frame 101 near the cup holder 104. The rotating component is disposed on the frame 101 and connected to the rotating motor 103 and the cup holder 104. Upon initial power-on, the position is calibrated using the positioning component to ensure that the soundproof cover 105 rotates inward and is open on the outside for placing snow on the cup holder 104. According to the customer's order, an appropriate amount of milk is placed in the shaker cup. The QR code of the order is affixed to the shaker cup, and then the QR code on the cup is scanned. After scanning, the LCD screen displays the placement of the shaker cup. The shaker cup is placed into the round hole of the cup holder 104. After the photoelectric sensor 106 on the side of the frame 101 detects the cup, the rotating motor 103 drives the cup holder 104 to rotate through the transmission component. Under the control of the positioning component, after the rotating motor 103 starts, the cup holder 104 rotates 180° and then stops. The shaker cup is rotated to the inside, and the soundproof cover 105 rotates to the outside. The lifting component drives the faucet steam rod 102 to descend and cooperates with the steam component to heat the milk in the shaker cup. At this time, the noise generated during the heating process is isolated by the soundproof cover 105, thereby greatly reducing the noise generated during the heating process.

[0027] Secondly, the bearing 107 is mounted on the frame 101 and connected to the cup holder 104; the two synchronous pulleys 108 are respectively mounted on the rotating motor 103 and the bearing 107. The rotating motor 103 drives the bearing 107 inside the cup holder 104 to rotate by the transmission of the two synchronous pulleys 108 and the transmission belt, thereby driving the cup holder 104 to rotate together.

[0028] Meanwhile, the magnetic Hall switch 109 is disposed on the frame 101 and located on one side of the frame 101; the magnet 110 is disposed on the cup holder 104 and located on the side of the cup holder 104 close to the magnetic Hall switch 109. Position calibration is performed by the magnetic Hall switch 109 and one of the magnets 110 on the cup holder 104 to ensure that the soundproof cover 105 rotates inward. At the same time, after the cup holder 104 rotates, the magnetic Hall switch 109 detects the other magnet 110, thereby controlling the cup holder 104 to rotate to 180° and then stop rotating.

[0029] Secondly, the drive motor 111 is fixedly connected to the frame 101 and located on one side of the frame 101; the ball screw 112 is mounted on the frame 101 and connected to the drive motor 111, and located on the side of the frame 101 close to the drive motor 111; the slider 113 is mounted on the ball screw 112 and connected to the faucet vent rod 102, and located on the side of the ball screw 112 close to the faucet vent rod 102; the limiting photoelectric sensor 114 is mounted on the ball screw 112 and located on the side of the ball screw 112 close to the slider 113; the lifting assembly is driven by the drive motor 111 driving the ball screw 112; the slider 113 is fixed on the ball screw 112; the entire faucet vent rod 102 structure is fixed on the slider 113, thereby realizing the lifting of the faucet vent rod 102. Depending on the amount of beverage consumed, the slider 113 descends from the upper limit photoelectric sensor 114 (origin position) to different positions (the descent position must ensure the faucet nozzle is in the center of the cup to ensure even heating). After reaching the designated position, the steam component turns on and begins heating. Once the temperature set by the QR code is reached, the faucet rises back to the origin position, and the user removes the cup. After removing the cup, the faucet continues to descend for wiping and spot spraying cleaning. Specifically, during the use of the faucet steam outlet 102, the drive motor 111 can drive the ball screw 112 to descend to a set position (the descent height is an internally set parameter). After heating to a suitable temperature (the heating temperature is an internally set parameter), the drive motor 111 drives the ball screw 112 to rise back to the initial position. The initial position is the sensing position of the upper limit photoelectric sensor 114, and the lower limit photoelectric sensor 114 is the safety position to prevent internal collisions caused by excessive parameter settings. After reaching the initial position, the rotating motor 103 rotates again, driving the cup holder 104 to rotate 180°, and the soundproof cover 105 is rotated to the inside again, and the shaker cup is rotated to the outside. The heated beverage is taken out. After the shaker cup is taken out, the photoelectric sensor 106 senses that there is no cup, and the drive motor 111 drives the ball screw 112 to descend to the low position, opening the heating component. The steam jets twice, one second each time, to expel the residual beverage inside the rod. At the same time, the faucet rod is wiped clean with a clean damp towel. Finally, the drive motor 111 drives the ball screw 112 to rise to the initial position, and the entire process is completed.

[0030] Additionally, the inner tank 115 is mounted on the frame 101, the water pump 116 is mounted on the frame 101, the water inlet solenoid valve 117 is mounted on the frame 101 and connected to the water pump 116, the one-way valve 118 is connected to both the water pump 116 and the inner tank 115, the air outlet solenoid valve 119 is connected to both the inner tank 115 and the faucet air outlet rod 102, the heating element is mounted on the inner tank 115, the heating tube 120 is mounted on the inner tank 115, and the water level probe 121 is mounted on the inner tank 115. The steam assembly on the inner tank 115 operates on the principle of a steam milk frother. Purified water enters the inner tank 115 through the water inlet solenoid valve 117, is pressurized by the water pump 116, and then passes through the one-way valve 118. The water level probe 121 at the lower end of the inner tank 115 senses the water, and the heating element 120 starts heating. During heating, the steam outlet solenoid valve 119 is opened, and the steam outlet rod 102 of the faucet heats the milk in the shaker cup. Water intake stops once the water level probe 121 reaches its maximum position. Heating generates pressure, and heating stops once the pressure reaches a set value. After subsequent use, the pressure decreases, and heating restarts. Water is consumed during heating, so water intake continues to maintain a stable heating and water intake state. An anti-backflow valve is used for steam heating. When the anti-backflow valve is de-energized, the beverage is connected to the outside atmosphere, achieving pressure balance and preventing backflow. When the anti-backflow valve is energized, steam in the inner tank 115 is discharged from the heating element 120, heating the beverage.

[0031] Finally, the inner soundproof cover 122 is fixedly connected to the frame 101 and is located on the side of the frame 101 near the soundproof cover shell 105. The inner soundproof cover 122 can isolate the noise of the internal structure of the frame 101 during operation and prevent moisture from entering the internal structure of the frame 101.

[0032] When using the steam milk frother with noise reduction function of this embodiment, the shaker cup is placed into the round hole of the cup holder 104. After the photoelectric sensor 106 on the side of the frame 101 senses the cup, the rotating motor 103 drives the cup holder 104 to rotate through the transmission component. Under the control of the positioning component, after the rotating motor 103 starts, the cup holder 104 rotates 180° and then stops. The shaker cup moves to the inside, and the soundproof cover 105 rotates to the outside. The lifting component drives the faucet steam outlet 102 to descend and cooperates with the steam component to heat the milk in the shaker cup. At this time, the noise generated during the heating process will be isolated by the soundproof cover 105, thereby greatly reducing the noise generated during the heating process.
