Description

Technical Field

[0001] The utility model relates to the technical field of milk frothers, in particular to an intelligent control steam milk frother. Background Art

[0002] The quality of coffee milk foam is related to the taste and quality of the beverage. In the market, steam engine brands such as Nordorf, Hanze, and Water Sprite are mostly used for heating. Although manual milk frothing can be done, it depends on experience and skills, and the quality is higher than that of automatic machines. The milk foam function of automatic coffee machines saves labor, but the fineness is difficult to control, affecting the taste and appearance. The key to milk foam lies in the regular high-speed rotation of milk and the timely supply of air. Manual frothing requires tilting the container due to the nozzle structure limitation, making it difficult to achieve intelligence. Chinese Patent CN221359345U attempts to improve the quality of milk foam by precisely controlling the ratio of steam to air. However, during the preparation of milk foam, it is often difficult to precisely control the mixing process of steam and milk, resulting in rough milk foam taste and uneven foam. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an intelligent control steam milk frother.

[0004] The technical solution adopted by the utility model is as follows:

[0005] An intelligent control steam milk frother includes a housing of the steam milk frother. A steam generator, an air pump, and a steam outlet device are disposed inside the housing. One end of the steam generator is connected to water through a water inlet valve, and the other end of the steam generator sends steam into the steam outlet device through a steam solenoid valve. At the same time, one end of the air pump is connected to air, and the other end of the air pump blows air into the steam outlet device. The steam and air are mixed to form a vortex in a container, and the milk in the container forms milk foam.

[0006] The steam milk frother further includes a control device. A safety device, a heating pipe, a water level sensor, and a temperature sensor are also disposed inside the steam generator. Among them, the water level sensor and the temperature sensor respectively collect the water level and temperature information of the steam generator and feedback them to the steam milk frother. The control device controls the heating pipe and the water inlet valve to adjust the steam temperature. The control device respectively controls the air pump and the steam solenoid valve to mix steam and air into the steam outlet device.

[0007] This technical solution realizes the precise control of steam temperature, pressure, flow rate, and air mixing ratio, thereby producing high-quality milk foam with a delicate texture. Specifically, the steam generator converts electrical energy into heat energy through a heating tube to heat water until it boils and generates steam. The control device monitors the steam temperature through a temperature sensor and adjusts the heating power of the heating tube according to a preset value to maintain the stability of the steam temperature, ensuring that the steam is mixed with milk within a suitable temperature range to produce ideal milk foam. The steam enters the steam outlet device through a steam solenoid valve, and at the same time, an air pump blows air into the same device. After the steam and air are mixed in the steam outlet device, they are ejected at high speed to form a vortex, and the vortex effect produces a strong stirring effect in the container, enabling the milk to be fully mixed with the steam and air to form delicate milk foam. The intensity and direction of the vortex have an important impact on the texture and taste of the milk foam. The control device automatically adjusts the working states of the heating tube, water inlet valve, air pump, and steam solenoid valve according to the feedback signals of the water level sensor and temperature sensor. When the water level is lower than the set value, the control device will start the water inlet valve to supplement water. When the steam temperature is too high or too low, it will adjust the heating power of the heating tube. According to the needs of milk foam production, the opening time and ratio of the air pump and steam solenoid valve are controlled. The closed-loop control mechanism ensures that the steam milk foam machine can operate stably and efficiently and produce high-quality milk foam. Safety devices (such as pressure sensors, overheat protectors, etc.) are used to monitor the operating state of the steam generator to prevent safety accidents caused by excessive pressure or temperature. Once an abnormal situation is detected, the safety device will immediately trigger a protection mechanism, such as shutting down the heating tube, cutting off the power supply, etc., to ensure the safety of the equipment and users.

The temperature probe is in contact with the milk in the container by being built into the bottom of the steam nozzle to control the temperature of the liquid heating. The temperature probe is connected to the control device.

[0016] This technical solution sets a pressure relief valve, an over-temperature circuit breaker, and a buzzer as safety devices, which automatically emit a beeping sound when the steam exceeds the preset safe range to remind the user to pay attention and take measures to ensure safety during use.

[0017] According to an embodiment of the present invention, the heating pipe is located inside the steam generator, powered by electricity, converts electrical energy into heat energy, heats the water in the steam generator to steam, and the steam temperature is controlled within a set range.

[0018] This technical solution installs a heating pipe inside the steam generator and uses power supply to convert electrical energy into heat energy to heat the water in the steam generator to the steam state, while ensuring that the steam temperature is maintained within the range of 100°C to 131°C to provide a stable heat source for making milk foam.

[0019] According to an embodiment of the present invention, the water level sensor is installed inside the steam generator to monitor the water level; the water level information is transmitted to the control device, and the water inlet valve is started to supplement water.
