Description

Automatic milk powder making machine with bottle sterilizing function

Technical Field

The invention relates to the field of milk powder preparing equipment, in particular to an automatic milk powder preparing machine with a milk bottle sterilizing function.

Background technique

There are two main types of milk makers currently on the market, one is a manual milk maker, and the other is an intelligent constant temperature milk maker. The manual milk maker is more convenient to use than a bottle, and the concentration of the milk can be controlled relatively well, but the operation is still relatively cumbersome; the intelligent constant temperature milk maker relies on a computer to control the concentration and temperature of the milk powder. People do not need to touch the milk powder during the entire process of making the milk, which not only greatly improves efficiency, but also increases safety and convenience.

The patent with authorization announcement number CN208388424U discloses an intelligent milk powder making machine: "The intelligent milk powder making machine includes a shell with a cavity inside, a milk powder feeding unit and a water feeding unit located in the cavity, and a milk making area located below the milk powder feeding unit and the water feeding unit and used to place a milk bottle." Although the milk powder feeding unit and the water feeding unit are used to realize automatic milk powder making, the milk powder feeding unit and the water feeding unit are very close to each other. Since the warm water for making milk powder will generate water vapor, it will enter the mouth of the milk powder feeding unit to make the mouth wet, which will easily cause the milk powder to stick to the mouth and cause bacteria to grow. At the same time, there is no special sterilization and disinfection device for the automatic milk powder making machine to solve the problem of bacterial growth. Therefore, it is urgent to design a new automatic milk powder making machine to solve the above problems.

Working principle: When working, insert the mouth of the milk bottle into the central column 43 in the steam sterilizing tank 41, then cover the sealing cap 42, then start the steam generator 18 to transport steam into the steam sterilizing tank 41 through the steam pipe and the steam outlet 45, and sterilize the whole body of the milk bottle with steam. After sterilization, then control the electric two-way valve 181 to work, so that the air outlet of the fan 17 is connected to the second steam conduit 182 through the air duct, then start the fan 17 and the electric heating wire 173 to work, the fan 17 transports the heated air into the steam sterilizing tank 41 through the air duct and the second steam conduit 182, and blows the milk bottle dry with hot air to prevent the steam from contacting the milk bottle to produce water droplets, causing the milk bottle to be wet and easy to breed bacteria. The pacifier is placed in the pacifier storage slot 35 provided on the pacifier storage plate 31, and then the steam generated by the steam generator 18 is transported to the steam outlet plate 34 through the first steam conduit 183, and then the pacifier is sterilized by steam; similarly, the electric two-way valve 181 is controlled to work, so that the air outlet of the fan 17 is connected to the first steam conduit 183 through the air duct, and the pacifier is blown dry by hot air. Put the sterilized milk bottle into the spring clip 152 inside the milk preparation room 5, then the electric push rod 15 drives the spring clip 152 to move, when the infrared receiver 153 receives the infrared signal emitted by the infrared transmitter 113 on the right side of the discharge nozzle 112, then transmits it to the single chip microcomputer 22, the single chip microcomputer 22 controls the electric push rod 15 to stop moving, so that the bottle mouth of the milk bottle is vertically aligned with the discharge nozzle 112, then the first drive motor 115 is started to drive the milk powder metering ball 111 to rotate, so that the milk powder is transported to the discharge nozzle 12 through the milk powder trough 114 and enters the milk bottle, by controlling the number of revolutions of the milk powder metering ball 111, the number of times the milk powder trough 114 is transported is controlled, and the purpose of quantitative transportation of milk powder is achieved. Then the spring clip 152 is driven forward by the electric push rod 15, when the infrared receiver 153 receives the infrared signal emitted by the infrared transmitter 113 on the right side of the water outlet 142, then transmits it to the single chip microcomputer 22, the single chip microcomputer 22 controls the electric push rod 15 to stop moving. Next, the boiled water in the first water storage chamber 13 and the hot water in the second water storage chamber 16 are mixed in the mixing chamber 14 to a set temperature. The temperature sensor is used to monitor the temperature in the mixing chamber 14 in real time. The mixed water enters the feeding bottle through the water outlet 142, and then the second drive motor 151 is started. The second drive motor 151 drives the spring clip 152 to rotate a specified angle. The forward and reverse rotation of the second drive motor 151 is controlled to realize the left and right shaking of the spring clip 152, and then the left and right feeding bottles are shaken to achieve uniform mixing of milk powder and water. By separating the water outlet 142 and the discharge nozzle 12 and first loading milk powder and then water, milk powder and water are prevented from being poured in at the same time. Since the hot air from the hot water will enter the discharge nozzle 12, the mouth of the discharge nozzle 12 will become moist, which will easily cause milk powder to stick to the mouth on the one hand, and easily breed bacteria on the other hand.
