And finally, the lower cover 30 is sleeved on the main frame 1, the lower cover 30 is sleeved in the threaded hole by means of plastic deformation and can be quickly taken down, and the function of the lower cover is to prevent an external force from accidentally touching the drumming membrane pair. (3) The temperature sensor 12 and the heating/refrigerating equipment 13 are arranged in the corresponding mounting hole (4), the contact D19 and the contact E20 are fixed on the main frame 1 and are connected with electric leads, then a sealing ring is arranged in a sealing groove of the top head 21, then a contact ring F21 is sleeved in the top head 17 to be fixed in an interference fit manner, a spring 18 is arranged in an inner cavity of the top head 17, then an outer cover 22 is arranged, and finally the whole is arranged in a mounting hole 1013 of the main frame; then, the water outlet hole interface 1041 is connected with a water inlet hole interface 1021 and a hose A27, the milk outlet hole interface 1031 is connected with a hose B28, the other end of the hose B28 is provided with the hose connector 32, then the hose connector 32 is used for installing the nipple 25, and after the nipple 25 is connected, the nipple 25 is installed in the installation area at the lowest part of the right side of the main frame 1; (5) the speed reducer 23 is arranged in the installation area on the right side of the main frame 1, a transmission shaft of the speed reducer penetrates through a shaft hole to be connected with a gear in a gear pair, and the shaft hole sealing measure is not detailed; (6) the air pump 24 is arranged and fixed, and an air nozzle of the air pump is connected with an air passage interface 1051 hose C29; (7) connecting all the wires, and then installing the control switch box 14 on the right side of the main frame for fixing; (8) rubber rings are installed in sealing grooves at both ends of the pipe 15, and then the valve core 16 is installed in a hole in the middle section of the pipe 15 to form an air valve, and then is installed in an installation hole 109 at the upper end of the air passage 105 to be fixed. (9) The piston 3 is arranged in the cylinder 2, then the lifting rod 4 penetrates through the piston 3 and the cylinder 2, the sealing ring is not detailed any more, after the cylinder assembly is arranged, the cylinder assembly is directly arranged in the main frame 1, the holding hand 107 of the main frame 1 can fix the cylinder assembly by means of elastic deformation, and the cylinder assembly is arranged in the main frame 1 by paying attention to the fact that the side hole of the cylinder assembly faces the pipe opening of the gas distributing valve. (10) The battery is placed in the battery compartment 106 and the battery cover 26 is attached, and the placement of the battery is conventional and will not be described in detail herein. Until the installation is completed.

When the automatic milk mixing and sucking device is used, milk powder or condensed milk is filled in the left barrel assembly, water on the right barrel assembly is filled in the right barrel assembly, the switch is turned on, the milk is sucked by the nipple 25, milk in the mixing area 101 is sucked out, the drum membrane 7 is made to drum, the speed reducer 23 and the power supply of the air pump machine 24 are switched on during the drum-up process, the gear pair rotates, the air pump machine 24 is inflated to move the piston of the left and right barrel assemblies downwards, the piston moves downwards to enable water to enter the mixing area 101 and the milk powder to enter the gear pair and then enter the mixing area 101, and finally milk is obtained. When the water is drunk up, the piston of the right cylinder assembly touches the water-up switch, and the speed reducer 23, the air pump 24 and the temperature controller all stop working.

When the milk sucker needs to be cleaned, the right barrel assembly is filled with water, milk powder in the left barrel assembly is emptied, then the air distributing valve is operated to enable the air pump 24 to only inflate the right barrel assembly, the protruding head 701 of the inflatable membrane is pressed, clean water directly enters the mixing area and then exits the nipple, cleaning operation is completed, various using methods and functions can be automatically operated as required, and the description is not repeated.

Example 2

Referring to fig. 25, 26 and 27, a square tubular milk sucking structure is shown, and the biggest difference between the embodiment 2 and the embodiment 1 is that the cartridge assembly is square and has no gear cover. Embodiment 2 has an advantage over embodiment 1 in that there is no need to provide a gear cover, and the gear can be loaded down from the receiving area on the gear cover, and the structure without the gear cover reduces the problems of installation and leakage caused by the gear cover. The square cylinder assembly is disadvantageous in that it is inferior in sealability, mounting operation of the packing, and movement of the piston.

Embodiment 1 can also be made in a gearless cover state, provided that the size of the gear pair is small enough to ensure that the gear pair can be loaded from the receiving area of the drum, which will not be described herein.

The embodiments in the present description are described in a progressive manner, each embodiment focuses on differences from other embodiments, and similar parts between the embodiments are referred to each other.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
