Furthermore, in the tea beverage industry, milk foam is frequently used to make milk tea, milk foam tea with cheese foam, and other drinks, providing consumers with a more diverse taste experience.
[0003] However, existing milk frothers require manual adjustment of the faucet height during actual use, which is inconvenient and prone to causing burns, resulting in poor practicality. Utility Model Content
[0004] The purpose of this utility model is to provide a steam milk frother with an automatic lifting and heating faucet, which aims to solve the technical problem that existing milk frothers require manual adjustment of the faucet height during actual use, which is inconvenient to operate and prone to burns, resulting in poor practicality.
[0005] To achieve the above objectives, this utility model employs an automatic lifting and heating steam milk frother, comprising a body, a heating mechanism, a water inlet solenoid valve, an inner tank, a heating steam faucet, a nozzle, a lifting assembly, a one-way valve, a quick-connect fitting, a safety valve, a vacuum valve, and a two-position three-way solenoid valve.
[0006] The machine body has a switch, a water inlet, and a barcode scanner. The inner tank is located inside the machine body. The water inlet solenoid valve is connected to the water inlet and is connected to the quick-connect fitting via a pipe. The one-way valve is connected to the end of the quick-connect fitting away from the solenoid valve and is connected to the inner tank via a pipe. The safety valve and the vacuum valve are both located on the inner tank. The steam inlet of the two-position three-way solenoid valve is connected to the steam outlet of the inner tank, and the atmospheric connection port of the two-position three-way solenoid valve is connected to an external air source. The inner tank is also equipped with a low water level probe, a high water level probe, a temperature sensing probe, and a reserved port. The lifting assembly is installed inside the machine body. The heating steam tap is connected to the lifting assembly and is connected to the steam outlet of the two-position three-way solenoid valve via a pipe. The nozzle is installed on the heating steam tap. The heating mechanism is used to heat the water inside the inner tank. The lifting assembly includes a stepper motor, a coupling, a lead screw, and a slider. The stepper motor is installed in the machine body, and the output end of the stepper motor is connected to the lead screw through the coupling. The slider is threadedly engaged with the lead screw, and the heating steam faucet is connected to the slider.
[0007] The heating mechanism includes a control component and a heating tube. The control component is disposed in the body of the machine, and the heating tube is connected to the inner tank. The heating tube is used to heat the water in the inner tank.
[0008] The steam milk frother with automatic lifting and heating faucet also includes a booster pump, which is installed on the pipe between the water inlet solenoid valve and the quick-connect fitting.
[0009] The steam milk frother with automatic lifting and heating faucet also includes an upper limit photoelectric sensor and a lower limit photoelectric sensor, both of which are installed on the machine body.
[0010] The upper limit photoelectric sensor and the lower limit photoelectric sensor are both slidably connected to the body and fixed by screws.
[0011] The steam milk frother with automatic lifting and heating faucet also includes a drain tray and a filter screen. The drain tray is located on one side of the machine body, and the filter screen is snapped into the drain tray.
[0012] The control components include an electrical control box, a main control board, and a transformer. The electrical control box is located inside the machine body, and both the main control board and the transformer are located inside the electrical control box.
[0013] The machine body is provided with two handles for easy gripping, and the two handles are symmetrically arranged on the machine body. The bottom of the machine body is also provided with multiple feet.
[0014] The steam milk frother with automatic lifting and heating faucet also includes an inner tank drain outlet, which is connected to the inner tank; the inner tank drain outlet has a plug.
[0015] This utility model discloses an automatic lifting and heating steam milk frother. In practical use, the recipe is pre-entered and a QR code is generated. After the customer accepts the order, they scan the corresponding QR code using the scanner to initiate heating. A stepper motor drives a lead screw to rotate, which in turn moves a slider, causing the heating steam nozzle to rise and fall. Depending on the amount of beverage, the slider lowers the heating steam nozzle from its original position to different locations (ensuring the nozzle nozzle is centered in the cup for even heating). Upon reaching the designated position, the steam outlet of the two-position three-way solenoid valve opens, initiating heating. Once the temperature set by the QR code is reached, the heating steam nozzle rises back to its original position. The user removes the cup, and the nozzle can then be lowered again for wiping and spot cleaning.
[0016] The steam system operates as follows: purified water enters through the inlet solenoid valve, is pressurized by the booster pump, and then enters the inner tank through the check valve. When the low-water-level probe on the inner tank detects water, the heating element activates heating. Water intake stops when the high-water-level probe is reached. Heating generates pressure, and heating stops once the pressure reaches a set value. After subsequent use, the pressure drops, and heating restarts. Water is consumed during heating, so water intake continues, maintaining a stable heating and water intake state.
[0017] During this process, by setting the one-way valve, the pressure in the inner tank will stabilize at 1.5 bar after the equipment is heated, preventing the pressure from squeezing out the boiling water and steam in the inner tank and causing damage to the equipment pipes and components; by setting the safety valve: if the equipment malfunctions and the heating element is continuously powered, the pressure in the inner tank will continue to rise, preventing accidents. When the pressure is too high, the safety valve will open to release pressure; by setting the vacuum valve: during the water intake process, the valve core falls to remove air from the inner tank; as the equipment continues to heat and the water vapor gradually increases, the valve core is pushed up by the water vapor, forming a closed space in the inner tank to store water vapor; by setting the temperature sensing probe: pressure and temperature have a certain linear relationship, the temperature sensing probe detects the pressure in the inner tank according to the linear relationship and converts it into temperature, which is displayed on the screen.
[0018] This method solves the technical problem that existing milk frothers require manual adjustment of the faucet height during actual use, which is inconvenient to operate and prone to burns, resulting in poor practicality. Attached Figure Description

[0030] This utility model provides a steam milk frother with an automatic lifting and heating faucet.
[0031] It includes a body 101, a heating mechanism, a water inlet solenoid valve 102, an inner tank 103, a heating steam faucet 104, a nozzle 105, a lifting assembly, a one-way valve 125, a quick-connect fitting 126, a safety valve 127, a vacuum valve 128, and a two-position three-way solenoid valve 129.
[0032] The body 101 includes a switch 106, a water inlet 107, and a barcode scanner 108. The inner liner 103 is located inside the body 101. The water inlet solenoid valve 102 is connected to the water inlet 107 and is connected to the quick-connect fitting 126 via a pipe. The one-way valve 125 is connected to the end of the quick-connect fitting 126 away from the solenoid valve and is connected to the inner liner 103 via a pipe. The safety valve 127 and the vacuum valve 128 are both located on the inner liner 103. The steam inlet 130 of the two-position three-way solenoid valve 129 is connected to the inner liner 103. The steam outlet of 03 is connected, and the atmospheric connection port 132 of the two-position three-way solenoid valve is connected to an external air source. The inner tank 103 is also equipped with a low water level probe 133, a high water level probe 134, a temperature sensing probe 135, and a reserved port 136. The lifting assembly is installed inside the body 101. The heating steam faucet 104 is connected to the lifting assembly, and the heating steam faucet 104 is connected to the steam outlet 131 of the two-position three-way solenoid valve 129 through a pipe. The nozzle 105 is installed on the heating steam faucet 104. The heating mechanism is used to heat the water in the inner tank 103.
[0033] The lifting assembly includes a stepper motor 109, a coupling 110, a lead screw 111, and a slider 112. The stepper motor 109 is installed inside the machine body 101. The output end of the stepper motor 109 is connected to the lead screw 111 through the coupling 110. The slider 112 is threadedly engaged with the lead screw 111. The heating steam faucet 104 is connected to the slider 112.
[0034] The heating mechanism includes a control component and a heating tube 113. The control component is disposed inside the body 101, and the heating tube 113 is connected to the inner tank 103. The heating tube 113 is used to heat the water in the inner tank 103.
[0035] The automatic lifting and heating steam milk frother also includes a booster pump 114, which is installed on the pipe between the water inlet solenoid valve 102 and the quick connector 126.
[0036] In this specific embodiment, the recipe is pre-entered and a QR code is generated. After accepting an order, the customer scans the corresponding QR code using the scanner 108 to initiate heating. The stepper motor 109 drives the lead screw 111 to rotate, which in turn moves the slider 112, causing the heating steam nozzle 104 to rise and fall. This allows the slider 112 to descend the heating steam nozzle 104 from its origin position to different positions depending on the amount of beverage (the descending position must ensure that the nozzle 105 of the heating steam nozzle 104 is in the center of the cup to ensure even heating). Once the designated position is reached, the steam outlet 131 of the two-position three-way solenoid valve 129 opens, initiating heating. After reaching the temperature set by the QR code, the heating steam nozzle 104 rises back to its origin position. The user removes the cup, and then the heating steam nozzle 104 continues to descend for wiping and spot cleaning.
[0037] The steam system operates as follows: purified water enters through the inlet solenoid valve 102, is pressurized by the booster pump 114, and then enters the inner tank 103 through the one-way valve 125. When the low-water-level probe 133 on the inner tank 103 detects water, the heating element 113 starts heating. Water intake stops when the high-water-level probe 134 is reached. 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, maintaining a stable heating and water intake state.
[0038] During this process, by setting the one-way valve 125, the pressure in the inner tank 103 will stabilize at 1.5 bar after the equipment is heated, preventing the pressure from squeezing out the boiling water and steam in the inner tank 103 and causing damage to the equipment pipes and components; by setting the safety valve 127: if the equipment malfunctions and the heating tube 113 is continuously powered, the pressure in the inner tank 103 will continue to rise, preventing accidents. When the pressure is too high, the safety valve 127 will open to release pressure; by setting the vacuum valve 128: during the water intake process, the valve core falls to remove air from the inner tank 103; when the equipment continues to heat up and the water vapor gradually increases, the valve core is pushed up by the water vapor, and the inner tank 103 forms a closed space to store water vapor; by setting the temperature sensing probe 135: pressure and temperature have a certain linear relationship, the temperature sensing probe 135 detects the pressure in the inner tank 103 according to the linear relationship and converts it into temperature, which is displayed on the screen.
[0039] This method solves the technical problem that existing milk frothers require manual adjustment of the faucet height during actual use, which is inconvenient to operate and prone to burns, resulting in poor practicality.
[0040] The steam milk frother with automatic lifting and heating of the faucet also includes an upper limit photoelectric sensor 115 and a lower limit photoelectric sensor 116, both of which are mounted on the body 101.
[0041] The upper limit photoelectric sensor 115 and the lower limit photoelectric sensor 116 are both slidably connected to the body 101 and fixed by screws.
[0042] In this specific embodiment, the upper limit photoelectric sensor 115 and the lower limit photoelectric sensor 116 limit the position of the slider 112, thereby limiting the vertical movement of the heating steam faucet 104. Furthermore, by employing a sliding connection and fixing it with screws, the positions of the upper limit photoelectric sensor 115 and the lower limit photoelectric sensor 116 can be adjusted.
[0043] Secondly, the steam milk frother with automatic lifting and heating of the faucet also includes a drain tray 117 and a filter screen 118. The drain tray 117 is located on one side of the body 101, and the filter screen 118 is snapped into the drain tray 117.
[0044] In this specific embodiment, the filter screen 118 is used to filter the overflowing or spilled liquid and temporarily store it in the drain tray 117.
[0045] Meanwhile, the control components include an electrical control box 119, a main control board 120, and a transformer 121. The electrical control box 119 is located inside the body 101, and the main control board 120 and the transformer 121 are both located inside the electrical control box 119.
[0046] In this specific embodiment, by setting up the electrical control box 119, the main control board 120 and the transformer 121, it is possible to easily control the heating tube 113 to heat the water in the inner tank 103 to a specified temperature.
[0047] In addition, the body 101 is provided with two handles 122 for easy gripping, and the two handles 122 are symmetrically arranged on the body 101. The bottom of the body 101 is also provided with a plurality of feet 123.
[0048] In this specific embodiment, the handle 122 makes it easier to lift the body 101, and the feet 123 improve placement stability.
[0049] Furthermore, the steam milk frother with automatic lifting and heating of the faucet also includes an inner tank drain outlet 124, which is connected to the inner tank 103; the inner tank drain outlet 124 has a plug 137.
[0050] In this specific embodiment, the inner liner drain port 124 facilitates the drainage of residual water from the inner liner 103.
[0051] This invention relates to an automatic lifting and lowering steam milk frother with a faucet. In practical use, the recipe is pre-entered and a QR code is generated. After receiving an order, the customer scans the corresponding QR code using the scanner 108 to initiate heating. The stepper motor 109 drives the lead screw 111 to rotate, which in turn moves the slider 112, causing the heating steam faucet 104 to rise and fall. Depending on the amount of beverage, the slider 112 lowers the heating steam faucet 104 from its origin position to different positions (ensuring the nozzle 105 of the faucet 104 is centered in the cup for even heating). Upon reaching the designated position, the steam outlet 131 of the two-position three-way solenoid valve 129 opens, initiating heating. After reaching the temperature set by the QR code, the heating steam faucet 104 rises back to its origin position. The user removes the cup, and the faucet 104 is then lowered again for wiping and spot cleaning.
[0052] The steam system operates as follows: purified water enters through the inlet solenoid valve 102, is pressurized by the booster pump 114, and then enters the inner tank 103 through the one-way valve 125. When the low-water-level probe 133 on the inner tank 103 detects water, the heating element 113 starts heating. Water intake stops when the high-water-level probe 134 is reached. 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, maintaining a stable heating and water intake state.
[0053] During this process, by setting the one-way valve 125, the pressure in the inner tank 103 will stabilize at 1.5 bar after the equipment is heated, preventing the pressure from squeezing out the boiling water and steam in the inner tank 103 and causing damage to the equipment pipes and components; by setting the safety valve 127: if the equipment malfunctions and the heating tube 113 is continuously powered, the pressure in the inner tank 103 will continue to rise, preventing accidents.
