The connecting tube 140 has a powder membrane 141 that is impermeable to powder at normal temperature. The powder diaphragm 141 is melted into hot water at a temperature of 50 ℃ or higher so that the powder of the crystal ice stored in the flexible powder bin 150 enters the cavity of the inner container 120. Preferably, the powder membrane 141 is made of edible material with specific taste, and the taste of the crystal ice powder can be changed after the powder membrane 141 is melted into hot water. Preferably, the powder membrane is a sugar-coated film made of brown sugar, brown sugar or crystal sugar. The taste of the powder membrane 141 is not limited thereto, and may have a fruity taste, a sour taste, or the like.

When the outer container 110 is squeezed, the pressure change of the pre-filled liquid caused by the contraction of the outer container 110 is transmitted to the flexible powder bin 150, so that the flexible powder bin 150 contracts or expands, and further, the crystal ice powder stored in the flexible powder bin 150 enters the cavity of the inner container 120 under the condition that the powder membrane 141 is melted. Preferably, when preparing the ice powder, the outer container 110 is pressed several times to uniformly mix the ice powder stored in the flexible powder bin 150 with the hot water introduced into the cavity of the inner container 120 through the hot water port 160 to prepare the ice powder.

The hot water port 160 penetrates the inner container 120 and the outer container 110. When preparing the ice powder, hot water for preparing the ice powder is introduced into the cavity of the inner container 120 through the hot water port 160. Preferably, the hot water port 160 has a check valve structure, and the temperature of the hot water introduced into the cavity of the inner container 120 through the check valve structure of the hot water port 160 is 50 to 100 ℃. Preferably, the hot water port 160 is detachably connected to the outer receptacle 110 and the inner receptacle 120.

As shown in fig. 2, the check valve of the present invention includes at least an upper flange 161, a lower flange 162, a fastening member 163, an O-ring 164, a piercing screw 165, a positioning guide sleeve 166, a sealing plate 167, an elastic member 168, and a check valve core 169. The upper flange 161 and the lower flange 162 are connected together by fasteners 163. An O-ring 164 is disposed between the upper flange 161 and the lower flange 162. The positioning guide sleeve 166 is fixed to the upper flange 161 by a through-hole screw 165. A sealing plate 167 is provided between the upper flange 161 and the positioning guide sleeve 166. One end of the check valve spool 169 is provided on the lower flange 162 via an elastic member 168, and the other end is provided on the seal plate 167. The check valve spool 169 is slidable up and down in the axial direction of the positioning guide sleeve 166. Preferably, the fastener 163 is a bolt. Preferably, the elastic member 168 is a spring. Preferably, the sealing plate 167 is a rubber sealing plate. The hot water port 160 of the present invention adopts a check valve structure, which can prevent the liquid in the inner container 120 from overflowing outwardly.

When the hot water heating valve is used, the upper end of the one-way valve is a hot water inlet, hot water pushes the one-way valve core 169 to move downwards through the perforated screw 165, the one-way valve core 169 is separated from the sealing plate 167, and therefore hot water can flow to the lower end outlet. When the hot water at the upper end stops injecting, the one-way valve core 169 moves upwards under the resultant force of the elastic component 168 at the lower end and the hot water, and the one-way valve core 169 is contacted with the sealing plate 167 and is pressed firmly, so that the purpose of stopping the flow is achieved.
