The constant temperature heating module 44 comprises a temperature sensor 441 and a heating module 442, the temperature sensor 441 is connected with the control module 45 and used for detecting the temperature of the water or the milk in the feeding bottle and feeding the temperature back to the control module 45, and specifically, the constant temperature heating module can be arranged on the bottom surface of the outlet portion 12 of the cup cover 1 and located on one side of the valve 13, and the constant temperature heating module is close to the mouth of the feeding bottle and can accurately sense the temperature of the water or the milk in the feeding bottle. Heating module 442 surrounds the inside wall setting of cup 2 and is connected with control module 45, realizes 360 degrees heats. When the temperature sensor 441 detects that the temperature of the water or milk in the feeding bottle is lower than a preset temperature, the control module 45 controls the heating module 442 to start heating, and turns off the heating module 442 when the heating is delayed to the preset temperature.
Further, the electronic control assembly further comprises a reminding module 46 connected with the control module 45, the intelligent milk brewing device further comprises a milk warming mode, in the milk warming mode, the control module 45 is used for controlling the constant-temperature heating module 44 to heat milk in the milk bottle to a preset temperature and keep the milk, and in the milk warming mode, when the time length reaches a second designated time length, the reminding module 46 is controlled to remind the user of time out in a preset mode. The invention provides four modes for entering the milk warming mode, which are respectively as follows:
in the first way, considering that the valve 13 is already opened after the milk is poured, when the feeding bottle is put into the cup body 2 again, if the control module 45 detects that the feeding bottle is not empty through the weight sensor, it represents that the user needs to warm the milk, i.e. the milk warming mode is entered.
The second kind of mode of entering, automatically controlled subassembly still include limit switch 23 of being connected with control module 45, and limit switch 23 is located the inside wall of cup 2, and control module 45 accessible limit switch 23 detects whether there is the feeding bottle to put into cup 2. On the basis, the control module 45 is further configured to enter a milk warming mode within a first specified time period after the valve 13 is opened, if the key module 42 is pressed again and the limit switch detects that a milk bottle is put into the cup body, mainly considering that the milk overshoot action is performed after the valve 13 is opened, and possibly the milk bottle is not drunk up during the next feeding and needs to be left for the next continuous use, so that if the key module 42 is pressed again and the cover body 1 is opened and put into the milk bottle within the first specified time period (e.g. 5 minutes), the user is considered to need to warm the milk.
In the third entering manner, instead of the manner of the first specified time period, the pressing manner of the key may be used to identify whether milk is required to be infused or milk warming is required, for example, if the user presses the key module 42 once, milk infusion is indicated, and if the user presses the key module 42 twice, milk warming is indicated, which is similar to the operation of a mouse. The control module 45 pre-stores the corresponding relationship between various working modes such as the milk brewing mode and the milk warming mode and the pressing mode of the key module 42, and when the control module 45 judges that the pressing mode of the key module 42 accords with the pressing mode of the preset milk warming mode, the control module enters the milk warming mode.
