[0048] An air inlet hole 111 is formed at the bottom of the protective shell 11 for balancing the air pressure inside the protective shell 11 , thereby ensuring that the air pressure of the juice bag 5 inside the protective shell 11 is constant.

[0049] A mounting seat 62 for mounting the flow rate control valve 8 is formed in the middle of the connecting cover 6, and clamping grooves 63 that are clamped with the flow rate control valve 8 are formed on the upper and lower sides of the mounting seat 62. A plurality of water outlets 64 arranged around the clamping grooves 63 are also formed on the mounting seat 62, and the plurality of water outlets 64 are all connected to the bottle body 1.

[0050] The snap-in groove 63 is formed with connected arc segments and straight segments, and the snap-in grooves 63 on the upper and lower sides of the mounting seat 62 correspond to each other. A plurality of water outlets 64 are arranged corresponding to a plurality of drinking ports 77 , and the water in the bottle body 1 can flow out through the water outlets 64 and the drinking ports 77 in turn.

[0051] The flow rate control valve 8 includes a control valve body 81 and a water outlet control body 82 formed on the top of the control valve body 81 . The water outlet control body 82 blocks a plurality of water outlets 64 and is placed on the top of the plurality of water outlets 64 .

[0052] The control valve body 81 and the water outlet control body 82 are made of rubber with an integrated structure. The water outlet control body 82 is a sheet structure, and the water outlet control body 82 is formed on the top of the control valve body 81. The water outlet control body 82 extends outward along the edge of the control valve body 81. When the water outlet control body 82 is clamped in the middle of the connecting cover 6, the water outlet control body 82 blocks several water outlets 64.

[0053] The flow rate control valve 8 is made of rubber, and the water outlet control body 82 can be deformed under pressure. The water outlet control body 82 is located between the water outlet 64 and the drinking port 77, and is used to seal the water outlet 64. When the drinking tube 74 sucks the bottle body, the water outlet control body 82 is deformed under the action of pressure, and the edge of the water outlet control body 82 is flipped upward, so that the water outlet 64 and the drinking port 77 can be connected, and the water in the bottle body 1 can be pressed out of the drinking tube 74 under the action of pressure.

[0054] At the same time, the water outlet control body 82 is reset after the pressure disappears, and the plurality of water outlets 64 are blocked again, thereby sealing the interior of the bottle body 1 .

[0055] A mounting hole 14 for mounting the juice pipe 71 is formed in the middle of the control valve body 81 and the mounting seat 62 . A double-layer clamping layer 85 clamped with the double-layer clamping groove 63 is formed on the control valve body 81 . The juice flow channel 83 is formed on the inner wall in the middle of the control valve body 81 .

[0056] The double-layer clamping layer 85 is composed of connected arc segments and straight segments, which correspond to the arc segments and straight segments of the clamping groove 63 for clamping respectively. Under the simultaneous clamping action of the arc segments and straight segments of the double-layer clamping layer 85, the setting of the double-layer clamping layer 85 in the connecting cover 6 is ensured, and the relative stability between the flow rate control valve 8 and the connecting cover 6 is ensured.

[0057] Two juice flow channels 83 symmetrically along the center of the flow rate control valve 8 are formed in the flow rate control valve 8, and the two juice flow channels 83 are located at the same horizontal height of the flow rate control valve 8, and there is a gap between the two juice flow channels 83. When the juice port 75 rotates to the gap between the two juice flow channels 83 as the juice pipe 71 rotates, the juice port 75 is blocked by the inner wall of the flow rate control valve 8. At this time, the juice bag 5 is in a completely closed state, and only water can flow out when the bottle body 1 is tilted or sucked.

[0058] When the juice outlet 75 rotates to the juice flow channel 83 as the juice pipe 71 rotates, the juice outlet 75 is connected to the drinking port 77 under the action of the juice flow channel 83. The depth of the juice flow channel 83 in the flow rate control valve 8 gradually deepens along the length direction of the juice flow channel 83, and the juice outlet 84 is connected to the deepest part of the juice flow channel 83, which is also the place with the maximum juice concentration.

[0059] Under the effect of the different depths of the juice flow channel 83, since the juice needs to flow out through the juice flow channel 83, the deeper position of the juice flow channel 83 can receive more juice, and similarly the shallower position of the juice flow channel 83 can only receive less juice. Therefore, the amount of juice flowing out is adjusted and controlled through the juice outlet 75 corresponding to the juice flow channel 83 of different depths.

[0060] In actual use, concentration marks 61 of 1-9 and X are marked on the connecting cover 6, X is located on two opposite sides of 1-9, and indicator heads 72 are formed on two opposite sides of the adjusting knob 7. The indicator heads 72 on both sides are respectively arranged corresponding to the two juice flow channels 83. When the indicator heads 72 on both sides of the adjusting knob 7 are simultaneously arranged toward the two X settings on the connecting cover 6, the juice port 75 rotates to between the two juice flow channels 83 as the juice pipe 71 rotates. At this time, the juice port 75 is blocked under the action of the inner wall of the flow rate control valve 8, and the juice bag 5 is in a completely closed state. When the bottle body 1 is tilted or sucked, only water can flow out.

[0061] When the indicator head 72 of the adjustment knob 7 is set toward one of the numbers 1-9, the juice outlet 75 rotates to the juice flow channel 83 along with the rotation of the juice pipe 71, thereby achieving communication between the juice outlet 75 and the drinking outlet 77.

[0062] As the indicator head 72 rotates toward the concentration mark 61 marked as 9, the size of the juice flow channel 83 connected to the juice outlet 75 gradually increases, thereby increasing the outflow of juice and thus increasing the juice concentration. Therefore, the concentration mark 61 marked as 9 is the maximum concentration of the juice in the juice cup, the concentration mark 61 marked as 1 is the minimum concentration of the juice in the juice cup, and the concentration mark 61 marked as X has no juice concentration.

[0063] A pull ring 13 is formed on the bottle cap body 3, and the pull ring 13 and the juice outlet unit 4 are located on opposite sides of the bottle cap body 3. A return valve 12 for balancing the internal air pressure of the bottle body 1 is installed on the bottle cap body 3, and the juice flow channel 83, the indicator head 72 and the concentration mark 61 are correspondingly arranged.
