[0035] Referring to Figures 1 and 2, Figures 1 and 2 show schematic diagrams of the structure of a drinking device in an embodiment of the present application. A drinking device 1 provided in an embodiment of the present application includes a main unit 2 and a water storage box 3. The main unit 2 includes a water outlet 22 and a discharge pipe 21, and the water storage box 3 is arranged to match the water outlet 22. The drinking device 1 is a special drinking device, which refers to a device that can prepare special beverages in addition to drinking water, such as a drinking device 1 for making sparkling water or a coffee machine for making milk foam.

[0036] The following is an introduction to a drinking device 1 with a function of making sparkling water. The main unit 2 of the drinking device 1 also includes an air pumping module (not shown in the figure), an air pumping port (not shown in the figure) and an air pumping button 23. The air pumping module is used to inject bubbles into the waterway to increase the flavor of the water. The air pumping module includes a gas tank disposed inside or outside the main unit 2. The gas tank is connected to the discharge pipe 21 and the air pumping port, respectively. When the gas pressure in the air pumping module is too high, the excess gas needs to be discharged to reduce the internal pressure. The water outlet 22 is located at the upper position of the main unit 2, and the outlet of the discharge pipe 21 is located at the lower position of the main unit 2. The drinking device 1 has a water outlet 22. When the user needs drinking water of different temperatures, the cup body is used to receive water at the water outlet 22. When the user needs to make sparkling water, the cup body receives a certain amount of drinking water at the water outlet 22, and then the cup body is placed at the air pumping port to pump air into the cup body to form sparkling water. When inflating the cup body, if the inflation button 23 on the main unit 2 is pressed for a long time, the inflation module will continue to work. Since the volume of the cup body is fixed, part of the gas remains in the pipeline inside the drinking device 1 and needs to be discharged to relieve the pressure, and some water will be brought out when the gas is discharged.

[0037] The water accumulation box 3 includes a box body 100 and a separation member 200. The box body 100 is provided with a accommodating chamber 101 and a connecting port 141, and the connecting port 141 can connect the accommodating chamber 101 and the discharge pipe 21, and the accommodating chamber 101 is provided with an accommodating area. The separation member 200 is arranged in the accommodating chamber 101, and the separation member 200 is used to separate the gas and liquid in the fluid discharged from the discharge pipe 21, so that the liquid enters the accommodating area. The separation member 200 includes a separation channel, an inlet 202, a liquid outlet 203 and an air outlet 204, and the inlet 202 is connected with the connecting port 141, and the liquid outlet 203 and the air outlet 204 can connect the separation channel with the accommodating area.

[0038] The above-mentioned water collection box 3 can not only realize the water collection purpose of the water collection box 3 itself, but also can be connected to the discharge pipe 21 so that the separation component 200 can separate the water vapor from the discharge liquid. The function integration is high, the separation component 200 structure does not occupy too much space, and there is no need to change the structure of the main unit 2 itself; the water collection box 3 is close to the discharge pipe 21 in position, which makes it easier to introduce the discharge liquid for subsequent separation work, and the original structure of the water collection box 3 can also make it more convenient to discharge the separated gas, and it has a larger liquid storage space, which improves the separation efficiency.

[0039] In one embodiment, the box body 100 includes a containing body 110 and a cover plate 120, the containing body 110 has the containing cavity 101, the containing cavity 101 is connected to the outside through the cover plate 120, the separation member 200 is detachably provided on the containing body 110, and the containing cavity 101 is divided into the separation channel located inside the separation member 200 and the containing cavity 102 located outside the separation member 200, and the containing cavity 102 is used to store the liquid.

[0040] As shown in FIG3 , the housing body 110 of the box body 100 includes a first side wall 111 facing the main unit 2, a second side wall 112 away from the main unit 2, and a bottom wall 113. The housing body 110 also includes a docking portion 130 connected to the main unit 2. The outer side of the first side wall 111 has a docking portion 130, which is used to connect to the corresponding position of the main unit 2 and fix the water collection box 3.

[0041] The box body 100 is provided with a support bar 114 . The support bar 114 is provided with a plurality of spaced and evenly distributed support bars 114 on the inner sides of the first side wall 111 and the second side wall 112 . The support bar 114 is located between the bottom wall 113 and the cover plate 120 , and is used to support and connect the cover plate 120 .

[0042] The inner side of the first side wall 111, the inner side of the second side wall 112 and the bottom wall 113 together form the containing body 110, and the containing body 110 has an opening, and the cover plate 120 is arranged at the opening and is used to partially cover the opening. Specifically, the outer periphery of the cover plate 120 is matched and connected with the edges of the first side wall 111 and the second side wall 112 to close the opening. A through hole 121 is provided on the cover plate 120, so that the containing chamber 101 is connected to the outside, and unnecessary liquids when using the drinking device 1, such as liquids overflowing from the cup body and dripping from the water outlet 22, can enter the containing chamber 102 of the containing chamber 101 through the through hole 121.

[0043] The separation member 200 includes a body 201 having an inlet 202, a liquid outlet 203 and an air outlet 204, and a separation channel is formed between the body 201 and the box body 100. The separation member 200 also includes a connecting pipe 210 and a guide member arranged in cooperation with the body 201.

[0045] By setting the height of the connecting pipe outlet 211 higher than the height of the inlet 202, the liquid flowing out of the connecting pipe 210 enters the accommodating chamber 101 and will not flow back to the inlet 201 and the connecting port 141. When the water collection box 3 is removed, the liquid stored in the accommodating chamber 101 of the water collection box 3 can also be prevented from flowing back, thereby avoiding liquid spillage when the water collection box 3 is removed, thereby improving the user experience.

[0046] Furthermore, the water accumulation box 3 is provided with a standard liquid level value, and an indicator mark line is provided at the standard liquid level value, which is used to prompt the cleaning of the liquid accumulation in the accommodating chamber 101 of the box body. The height of the connecting pipe outlet 211 is higher than the standard liquid level value in the water accumulation box 3, which further prevents the accumulated water from flowing back.

[0047] In one embodiment, the inlet 202 and the outlet of the connecting tube 210 are oriented in different directions, and the box body 100 further includes a liquid inlet pipe 140, and the liquid inlet pipe 140 and the connecting tube 210 are oriented in different directions, so that the mixed fluid generates a turbulent effect when passing through the connecting tube 210. Specifically, the inlet 202 is arranged toward the main unit 2, and the outlet of the connecting tube 210 is arranged in a direction away from the bottom wall 113 of the box body 100, and the inlet 202 and the outlet of the connecting tube 210 can be arranged vertically.

[0048] In one embodiment, as shown in FIG. 7 , the connecting tube 210 further includes a main body 212, an inner curved portion 213 and an outer curved portion 214. The main body 212 extends in a vertical direction, and the inner curved portion 213 is curvedly disposed between the inlet and the main body 212. The outer curved portion 214 is curvedly connected between the main body 212 and the box body 100.

[0049] Specifically, between the connection port 141 and the inlet port 202, the liquid inlet pipe 140 formed on the box body 100 is arranged in the horizontal direction, the inlet port is arranged at the end of the liquid inlet pipe 140, the inner curved portion 213 connects the liquid inlet pipe 140 and the main body 212, and the connecting pipe outlet 211 is formed at the end of the main body 212. The outer curved portion 214 connects the main body 212 and the box body to assist in guiding the fluid and to buffer the fluid, and the bending direction of the outer curved portion 214 is opposite to the bending direction of the inner curved portion 213.

[0050] In one embodiment, the separation channel includes the above-mentioned connecting tube 210, the inlet of the connecting tube 210 is the inlet 202, the outlet of the connecting tube 210 is the connecting tube outlet 211, and is part of the separation channel, and there is a gap between the outlet of the connecting tube 210 and the inner wall of the separation component 200, so that the gas-liquid mixture flowing out of the connecting tube 210 can pass through the gap.

[0051] The connecting pipe 210 is connected to the discharge pipe 21 through the liquid inlet pipe 140, the inlet of the liquid inlet pipe 140 is the connecting port 141, and the outlet of the liquid inlet pipe 140 is connected to the inlet (i.e., the inlet port 202) of the connecting pipe 210. The gas-liquid mixture discharged from the main unit 2 enters the separation channel through the outlet of the discharge pipe 21, the connecting port 141 of the liquid inlet pipe 140, the liquid inlet pipe 140, and the inlet of the connecting pipe 210 in sequence.

[0052] It is understandable that the connecting tube 210 and the liquid inlet tube 140 can be an integrated structure, or the connecting tube 210, the liquid inlet tube 140 and the box body 100 are an integrated structure; or, in other embodiments, the connecting tube 210 can also be a part of the separation component 200.

[0053] In one embodiment, the water collection box 3 further includes a guide member 230, the guide member 230 is provided on the separation member 200, and there is a flow gap between the guide member 230 and the box body 100; and / or, there is a flow gap between the guide member 230 and the connecting pipe outlet 211, and the guide member 230 is used to shield the connecting pipe outlet 211 in the vertical direction. The guide member 230 can also shield the connecting pipe outlet 211 in the separation channel to a certain extent, preventing the airflow carrying liquid from flowing through and causing droplets to splash.

At the same time, the guide member 230 prevents the liquid entrained in the fluid from splashing upward from the connecting pipe outlet 211.

[0055] In one embodiment, at least one separation wall 220 is further provided in the separation channel between the inlet 202 and the liquid outlet 203. The separation wall 220 is provided in the box body 100, and there is a flow gap between the separation wall 220 and the separation member 200. The separation wall 220 is used to separate and guide the flow direction of the fluid, so that the gas in the mixture is easier to discharge and the gas-liquid separation is easier to achieve; the separation wall 220 can also change the flow direction, and the gas and liquid are guided to be discharged from the separation member 200 respectively; the separation wall 220 cooperates with the guide member 230, matches the position of the liquid outlet 203, performs a second flow disturbance, and changes the flow direction of the fluid, and finally enters the liquid outlet 203 or the gas outlet 204 through the flow gap.

Correspondingly, the buffer portion 223 is provided in the middle of the separation wall 220, matching the position of the outlet of the inlet 202 or the connecting pipe 210.

[0059] The buffer portion 223 includes an arc segment 2231 and a protruding segment 2232. In the embodiments shown in Figures 3 and 4, the buffer portion is in a "human" shape. Two arc segments 2231 are symmetrically arranged. A protruding segment 2232 protruding toward the connecting tube outlet is formed between the two arc segments 2231. The arc surface of the arc segment 2231 is concave into an arc in the direction away from the connecting tube outlet.

[0061] In one embodiment, the separation member 200 includes a top wall 206 and a side wall 205 arranged around the top wall 206, so that the separation member has a cap-shaped structure. The side wall 205 is provided with a liquid outlet 203 and a gas outlet 204, and the separation wall 220 is spaced apart from the top wall 206 to form a liquid channel on one side of the separation wall 220 facing the inlet 202 and a gas channel on the other side. The top wall 206 is arranged substantially parallel to the bottom wall 113 of the box body 100 or substantially perpendicular to the separation wall 220, and the side wall 205 is substantially perpendicular to the top wall 206 and spaced apart from the separation wall 220.

The separation channel includes: the connecting tube 210, the fluid channel formed between the connecting tube outlet and the main body 201, the fluid channel formed between the connecting tube outlet and the guide member 230, the fluid channel formed between the guide member 230, the connecting tube 210 and the separation wall 220 respectively, and the fluid channel formed between the guide member 230 and the main body 201 of the separation component 200.

[0073] In one embodiment, the separation member 200 includes at least one engaging portion, and the engaging portion is detachably connected to the separation wall 220 and / or the engaging portion is detachably connected to the box body 100 .

[0074] Specifically, the engaging portion includes a first connection hole 207 and a second connection hole 231. A first connection buckle is provided on the separation wall 220, and the first connection hole 207 is matched and connected with the first connection buckle to realize the detachable connection between the separation member 200 and the separation wall 220. A second connection buckle is provided on the connecting tube 210, and the second connection hole 231 is matched and connected with the second connection buckle to realize the detachable connection between the separation member 200 and the connecting tube 210. The connecting tube 210 and the separation wall 220 are both formed on the box body 100, and finally the detachable connection between the separation member 200 and the box body 100 can be formed.

[0075] The first connection hole 207 is located at the first separation edge 221 of the separation wall 220, and correspondingly, the first connection hole 207 is located at the first side surface 2051 of the separation member 200. The second connection hole 207 is located near the outlet of the connecting pipe 210, and correspondingly, the second connection hole 231 is located at the peripheral side of the guide member 230 on the separation member 200.
