Description

TECHNICAL FIELD

[0001] The utility model relates to the field of maternal and child products, more exactly, to a milk shaker. BACKGROUND

[0002] In the related art, some waterless milk shakers use hot air for heating, heat the milk bottle through the hot air, heat the milk bottle, and adjust the temperature of the refrigerated breast milk or the brewed milk powder in the milk bottle to achieve the purpose of warming the milk. And through the rack or belt structure, the milk basket in the milk warmer is reciprocatingly rotated or circumferentially moved to make the milk powder in the milk bottle evenly brewed, so as to avoid the problems of milk powder caking and granulating.

[0003] The existing milk shaker includes a milk bottle, which is mostly detected by a contact type NTC temperature sensor. Since the milk bottle reciprocatingly rotates, the contact type NTC temperature sensor rubs, and the detection result is inaccurate. To avoid the mutual rubbing between the contact type NTC temperature sensor and the milk bottle, some milk shakers adopt an open hole to arrange an infrared non-contact temperature sensor, which avoids the rubbing after the contact and completes the temperature measurement. However, since the rays emitted by the infrared non-contact temperature sensor pass through, a detection hole needs to be arranged at the bottom of the milk basket, so that part of the hot air blown to the milk basket can pass through the detection hole and interfere with the infrared non-contact temperature sensor, and the liquid on the milk bottle may fall into the position of the infrared non-contact temperature sensor through the detection hole, which leads to the decrease of the temperature measurement accuracy. SUMMARY

[0004] The technical problem to be solved by the utility model is to provide a milk shaker, which avoids the interference of external airflow and liquid on the infrared sensor and has high temperature measurement accuracy.

[0005] The technical solution of the utility model is to provide a milk shaker with the following structure, which comprises a base and a heating cup rotationally connected to the base. The bottom of the heating cup is provided with a through hole. The base is internally provided with a detection seat. The end of the detection seat is provided with an opening hole opposite to the through hole. The opening hole is sealingly matched with a lens. The detection seat is internally provided with an infrared sensor opposite to the lens.

[0006] As an improvement of the utility model, the lens comprises a protruding part protruding from the end of the detection seat.

[0007] As an improvement of the utility model, the protruding part has an arc-shaped or semicircular vertical cross-sectional shape.

[0008] As an improvement of the utility model, the lens has a concave back part, which forms a containing groove for containing the infrared sensor.

[0009] As an improvement of the utility model, the containing groove and the infrared sensor are provided with a gap.

[0010] As an improvement of the utility model, the lens comprises an annular stepped groove, the detection seat is provided with an annular boss matched with the annular stepped groove, and a sealing ring is arranged between the annular stepped groove and the annular boss.

[0011] As an improvement of the utility model, the outer surface of the protruding part is provided with a quick water-repellent layer.

[0012] As an improvement of the utility model, the detection seat comprises a bottom plate and a boss arranged on the bottom plate, the opening is arranged at the end of the boss, and the bottom plate is provided with a first drainage port.

[0013] As an improvement of the utility model, the base is provided with a second drainage port matched with the first drainage port.

[0014] After the above structure is adopted, compared with the prior art, the milk shaker has the following advantages: the infrared sensor is protected by arranging the lens, the lens is arranged on the detection seat and is far away from the heating cup, the possibility that the lens and the infrared sensor are affected is greatly reduced, and when part of airflow and liquid interfere with the detection seat, the lens can greatly reduce the airflow and liquid interference on the detection precision of the infrared sensor, so that the infrared sensor can accurately measure the temperature.
