When the knob 101 is loosened, the torsion spring 104 acts on the limiting plate 103 in the opposite direction, so that the limiting plate 103, the ratchet plate 102 and the knob 101 rotate in the opposite direction and reset, the ratchet plate 105 and the ratchet plate 102 are driven by the ratchets, and the first ratchets 1021 are arranged on the elastic arms 1025, so that in the resetting process, the first ratchets 1021 and the second ratchets 1051 slip and are not linked, at the moment, the ratchet plate 105 cannot rotate along with the ratchet plate 102, so that the valve rod 9 cannot rotate, in addition, the powder outlet impeller 11 in the embodiment has three blades 111 arranged at equal intervals along the circumferential direction, and the radian of the arc-shaped limiting clamping groove 1031 is adapted to the included angle between two adjacent blades 111, that is, the angle of each rotation of the knob 101 is 120 °, so that during each use, a powder quantifying area always corresponds to the position of the first outlet 62, and a powder quantifying area 8 corresponds to the position of the second outlet 71, so that the position of the valve stem 9 and each vane 111 can be accurately controlled.

Portable milk machine that dashes still disposes adapter 15, and adapter 15 is the cavity setting, and adapter 15 has first connecting portion 151 and second connecting portion 152, first connecting portion 151 and heating cavity 134 looks adaptation, and the lateral wall of first connecting portion 151 is equipped with the joint external screw thread 153 with cavity internal thread 135 looks adaptation, and the inside wall of second connecting portion 152 is equipped with and connects internal thread 154.

Through configuring the adapter 15, when the feeding bottle bottleneck that the user chose for use and cavity internal thread 135 fit for, can be directly be connected the bottleneck of feeding bottle with the cavity internal thread 135 of heating cavity 134 when using, and when the feeding bottle bottleneck that the user chooseed for use and cavity internal thread 135 did not match, only need with the help of first connecting portion 151 with adapter 15 threaded connection to heating cavity 134, then with the second connecting portion 152 of the bottleneck threaded connection to adapter 15 of feeding bottle again, can realize the heating to liquid in the feeding bottle equally. For feeding bottles with different mouth specifications on the market, different use requirements of users can be met only by configuring adapters 15 of different models (it needs to be explained that the first connecting part 151 of the configured adapter 15 needs to be matched with the heating cavity 134).

In this embodiment, the inner side wall of the second connecting portion 152 is provided with an annular step 155, the annular step 155 is embedded with a joint sealing ring 156, and when the mouth of the feeding bottle is screwed to the second connecting portion 152, the mouth of the feeding bottle abuts against the joint sealing ring 156 on the annular step 155, so that a sealing effect is achieved.

The above description is only a preferred embodiment of the present invention, and all equivalent changes or modifications of the structure, characteristics and principles described in the present invention are included in the scope of the present invention.
