[0043] In order to keep the following description of the embodiments of the present application clear and concise, the detailed descriptions of known functions and known components are omitted in the present application.

[0044] As Figure 1 and Figure 3As shown, an embodiment of the present application provides a water outlet mechanism, which is used, for example, on a water bottle 5 for making soda water. It can be understood that in addition to soda water, other beverages with a bubbly nature can also be in the water bottle 5, that is, the pressure in the water bottle 5 is slightly greater than the external atmospheric pressure. For the convenience of description, soda water and other beverages with a bubbly nature will be collectively referred to as bubbly water in the following text.

[0045] The water outlet mechanism includes a water outlet pipe 3 provided in the water bottle 5, and a water outlet channel 1, a water outlet 2, and a pressing assembly 4, all of which are provided on the bottle top cover 51 or the bottle body of the water bottle 5. The water outlet 2 is connected to the water outlet channel 1. The pressing assembly 4 can move relative to the water bottle 5 and has a first position and a second position. When the pressing assembly 4 is in the first position, the connection between the water outlet channel 1 and the water outlet pipe 3 is cut off; when the pressing assembly 4 is in the second position, the water outlet channel 1 and the water outlet pipe 3 are connected, and the bubbly water in the water bottle 5 sequentially enters the water outlet pipe 3, the pressing assembly 4, and the water outlet channel 1 and flows out from the water outlet 2.

[0046] It can be understood that the water outlet mechanism of the present application can be provided at the bottle mouth of the water bottle 5 or at the upper part of the bottle body of the water bottle 5. When the water outlet mechanism is provided at the bottle mouth, all the components constituting the water outlet mechanism are provided on the bottle top cover 51; when the water outlet mechanism is provided on the bottle body, a through hole communicating with the inside of the water bottle 5 needs to be opened on the bottle body, and the position of the through hole is above the liquid level in the water bottle 5, and a sealing cover is provided at the through hole, and all the components constituting the water outlet mechanism are provided on the sealing cover. The following will take the water outlet mechanism provided on the bottle top cover 51 as an example for detailed description.

[0047] Such as Figure 2 And Figure 4As shown, the water outlet mechanism includes a water outlet channel 1, a water outlet 2, a water outlet pipe 3, and a pressing component 4. The water outlet channel 1 is provided on the bottle top cover 51; the water outlet 2 is provided on the bottle top cover 51 and connected to one end of the water outlet channel 1, or the water outlet 2 is formed by extending from one end of the water outlet channel 1 to the peripheral side or bottom side of the bottle top cover 51. The sparkling water in the water outlet channel 1 can flow out through the water outlet 2 and be provided to the user. The water outlet pipe 3 is provided in the water bottle 5. The lower end of the water outlet pipe 3 extends below the water surface of the water bottle 5, and the upper end of the water outlet pipe 3 is located near the bottle top cover 51. In order to enable all the sparkling water in the water bottle 5 to flow out and avoid waste, the lower end of the water outlet pipe 3 can extend to the bottom of the water bottle 5. The pressing component 4 is provided on the bottle top cover 51 and is located between the other end of the water outlet channel 1 and the upper end of the water outlet pipe 3, and is used to cut off or conduct the connection between the water outlet pipe 3 and the water outlet channel 1. That is, by operating the pressing component 4, the other end of the water outlet channel 1 can be connected to the upper end of the water outlet pipe 3 or the connection between the other end of the water outlet channel 1 and the upper end of the water outlet pipe 3 can be cut off. The pressing component 4 can move relative to the bottle top cover 51 and has a first position and a second position. When the pressing component 4 is in the first position, the pressing component 4 cuts off the connection between the water outlet channel 1 and the water outlet pipe 3, that is, the sparkling water in the water outlet pipe 3 cannot enter the water outlet channel 1; when the pressing component 4 is in the second position, the pressing component 4 connects the water outlet channel 1 and the water outlet pipe 3, and can enable the sparkling water in the water bottle 5 to enter the water outlet pipe 3, the pressing component 4, and the water outlet channel 1 in sequence and flow out through the water outlet 2.

[0048] The water outlet mechanism of the embodiment of the present application can control the sparkling water in the water bottle 5 to enter the water outlet channel 1 and flow out through the water outlet 2 by operating the pressing component 4. When the user needs to drink the sparkling water in the water bottle 5, the sparkling water in the water bottle 5 can be directly made to flow out by operating the pressing component 4, without the need to disassemble the bottle top cover 51 to pour the water bottle 5, which improves the convenience of use and the user experience is better.

[0049] In some embodiments, continuing to combine Figure 2 and Figure 4 , the pressing component 4 has a water cavity 411, an inlet 412 communicating with the water cavity 411, and a water outlet hole 4211. The inlet 412 is connected to the upper end of the water outlet pipe 3, so that the sparkling water in the water bottle 5 can enter the water cavity 411 through the water outlet pipe 3. When the pressing component 4 is in the first position, the water outlet hole 4211 is offset from the other end of the water outlet channel 1, and the connection between the water outlet pipe 3 and the water outlet channel 1 is cut off, and the sparkling water in the water bottle 5 cannot enter the water outlet channel 1. When the pressing component 4 is in the second position, the water outlet hole 4211 faces the other end of the water outlet channel 1, the water outlet pipe 3 is connected to the water outlet channel 1, and the sparkling water in the water bottle 5 can enter the water outlet channel 1 and flow out through the water outlet 2. The structure of the pressing component 4 is reasonable, which is conducive to realizing the connection or disconnection (cut-off) between the water outlet pipe 3 and the water outlet channel 1 when it switches between the first position and the second position.

[0050] like Figure 2 and Figure 4 As shown, the pressing assembly 4 includes a main body 41, a pressing member 42 and a reset member 423. The main body 41 is fixed in the bottle top cover 51, and a water cavity 411 is provided in the main body 41. The water cavity 411 penetrates to the upper end of the main body 41 so that the upper end of the main body 41 is open, and a water inlet 412 is provided at the lower end of the main body 41. The side of the main body 41 is provided with an opening 413 communicating with the water cavity 411, and the other end of the water outlet channel 1 is connected to the opening 413, that is, the other end of the water outlet channel 1 is connected to the opening 413, and the connection is sealed, so that the bubble water in the water cavity 411 can only enter the water outlet channel 1 without leaking out.

[0051] The lower part 421 of the pressing member 42 extends into the water cavity 411 through the opening of the main body 41, and blocks the opening to prevent the bubble water in the water cavity 411 from leaking through the opening. A passage 4212 is provided in the lower part 421 of the pressing member 42, which runs through to the bottom end thereof, and a water outlet hole 4211 is provided on the peripheral side of the lower part 421 of the pressing member 42, which is connected to the passage 4212, and the peripheral side of the pressing member 42 is sealed and fitted with the inner cavity wall of the water cavity 411. The upper part of the pressing member 42 extends out of the bottle top cover 51 to form a pressing part 422. When the pressing part 422 is pressed, the lower part 421 of the pressing member 42 moves along the water cavity 411, so that the pressing member 42 is switched from the first position to the second position, and the water outlet hole 4211 and the other end of the water outlet channel 1 are changed from the initial offset to the two being opposite. The relative here does not mean that the water hole 4211 and the other end of the water outlet channel 1 completely overlap, but also includes that the two are only partially relative. When the two are only partially relative, it is necessary to ensure that the bubble water in the water cavity 411 can enter the water outlet channel 1 through the water outlet hole 4211.

[0052] The reset member 423 is disposed between the main body 41 and the pressing member 42, and is used to apply a force to the pressing member 42 to reset it from the second position to the first position, so that the water outlet hole 4211 and the other end of the water outlet channel 1 are transformed from relative to each other to offset.

[0053] The pressing member 42 of the present application can be switched from the first position to the second position under the pressing action of an external force, and automatically reset to the initial state of the first position under the action of the reset member 423 when the pressing is cancelled. The water outlet pipe 3 and the water outlet channel 1 are connected or disconnected by pressing and automatically resetting, and the structural principle is simple and reasonable, the operation is convenient and fast, and the manufacturing cost is low.

[0054] When the pressing member 42 is not pressed, it is in the first position, the water outlet hole 4211 is misaligned with the other end of the water outlet channel 1, and the bubble water in the water bottle 5 cannot enter the water outlet channel 1 through the water outlet pipe 3. Figure 2When the user needs to drink bubble water, the user presses the pressing portion 422 downward, and the pressing member 42 moves downward. When the pressing member 42 moves to the second position, the water outlet hole 4211 and the other end of the water outlet channel 1 are opposite to each other and connected. In the process of the pressing member 42 pressing downward, pressure is applied to the water in the water bottle 5. When the water outlet hole 4211 and the other end of the water outlet channel 1 are opposite to each other and the water outlet pipe 3 is connected to the water outlet channel 1, the bubble water in the water bottle 5 enters the water outlet pipe 3 under pressure, and then enters the water outlet channel 1 through the water cavity 411 and flows out from the water outlet 2. Figure 3 , Figure 3 and Figure 4 The black dots in the figure represent flowing bubble water. When the amount of bubble water flowing out reaches the amount required by the user, the pressing part 422 is released, and the pressing part 42 is reset upward to the first position under the action of the reset part 423, waiting for the next use of the user.

[0055] like Figure 2 and Figure 4 As shown, the main body 41 is columnar and vertically arranged, the water cavity 411 extends along the axial direction of the main body 41, and the cross-section of the water cavity 411 is circular. The lower part 421 of the pressing member 42 is hollow tubular and adapted to the water cavity 411. The lower part 421 of the pressing member 42 is sleeved with a first sealing ring 425 respectively located above and below the water outlet 4211 to seal the upper and lower sides of the water outlet 4211 respectively. In this way, the sealing between the circumferential side of the lower part 421 of the pressing member 42 and the inner cavity wall of the water cavity 411 is achieved, so that the bubble water in the water cavity 411 can only enter the water outlet channel 1 without leakage.

[0056] The specific structure of the reset member 423 is not limited, as long as it can provide a force for the pressing member 42 to reset from the second position to the first position. Figure 2 and Figure 4 As shown, the reset member 423 shown in this embodiment is a spring, the upper end of the spring extends into the passage 4212 of the lower part 421 of the pressing member 42, and abuts against the top of the passage 4212. The passage 4212 forms a limit for the spring to prevent it from shaking, and the lower end of the spring abuts against the bottom of the water cavity 411. When the pressing portion 422 presses downward to switch the pressing member 42 from the first position to the second position, the spring is compressed and accumulates elastic potential energy. When the force acting on the pressing portion 422 is cancelled, the spring releases the elastic potential energy and pushes the pressing member 42 to move upward, so that the pressing member 42 switches from the second position to the first position.

[0057] In some embodiments, the combination Figure 2 and Figure 4, the water inlet 412 of the main body 41 extends downward to form a connector 424 that extends into the water bottle 5, and the upper end of the water outlet pipe 3 is connected to the connector 424. By providing the connector 424, it is convenient to connect the water outlet pipe 3 to the water inlet 412 of the main body 41.

[0058] As Figure 2 and Figure 4 shown, a protruding portion 514 extends outward from the side of the bottle top cover 51, and a water outlet 2 is provided on the side where the free end of the protruding portion 514 faces downward. The water outlet channel 1 extends from inside the bottle top cover 51 to the water outlet 2 of the protruding portion 514. By designing the protruding portion 514 on the bottle top cover 51, not only sufficient space is provided for the arrangement of the water outlet channel 1, but also it is convenient to design the water outlet 2 to face downward, facilitating users to receive water.

[0059] In some embodiments, as Figure 2 and Figure 4 shown, a limiting structure 4221 extends outward from the peripheral side of the bottom end of the pressing portion 422, and the limiting structure 4221 can be an annular or intermittent flange. A through hole (the through hole is blocked by the pressing portion 422 and not shown) is provided on the bottle top cover 51, and the pressing portion 422 passes through the through hole and extends out of the bottle top cover 51. When the pressing member 42 is in the first position, the limiting structure 4221 abuts against the lower peripheral edge of the through hole. By providing the limiting structure 4221, it is avoided that the pressing member 42 is disengaged from the bottle top cover 51 when being reset to the first position by the reset member 423, and the pressing member 42 is accurately positioned at the first position.

[0060] The embodiment of the present application also provides a sparkling water machine. As Figure 5 , Figure 6 and Figure 8 shown, the sparkling water machine includes a water bottle 5 and a gas cylinder 6. The gas cylinder 6 is used to supply gas into the water bottle 5 to make the water in the water bottle 5 form sparkling water; the sparkling water machine further includes the water outlet mechanism in any of the above embodiments, and the water outlet mechanism is arranged on the bottle top cover 51 of the water bottle 5. This sparkling water machine can discharge the sparkling water in the water bottle 5 through the water outlet mechanism and provide it to the user without removing the bottle top cover 51, without having to pick up the water bottle 5 to pour the sparkling water, improving the convenience of user use.

[0061] As Figure 2 and Figure 4As shown, the bottle top cover 51 includes an inner cover 511 and an outer cover 512. The inner cover 511 seals the upper bottle mouth and forms a seal with the upper bottle mouth. The outer cover 512 is disposed outside the inner cover 511 and forms a cavity 513 therebetween. The protruding portion 514 extends horizontally outward from the side of the outer cover 512, and the protruding portion 514 is a hollow structure, and the hollow structure communicates with the cavity 513. The water outlet passage 1 is disposed in the hollow structure and the cavity 513. The main body 41 of the pressing assembly 4 is fixed in the cavity 513, and the connecting head 424 at the bottom end of the main body 41 passes through the inner cover 511 and extends into the water bottle 5. The through hole is disposed on the portion of the outer cover 512 corresponding to the top end of the main body 41.

[0062] In some embodiments, as Figure 5 and Figure 6 shown, the sparkling water maker further includes a base 7. An air supply joint 8 extending out of the top surface of the base 7 is disposed in the base 7. The air inlet end of the air supply joint 8 is communicated with the gas cylinder 6 through an air supply pipe 9. See Figure 8 . As Figure 7 shown, a bottom cover 52 is provided at the lower bottle mouth of the water bottle 5. An air inlet 521 communicating with the inside of the water bottle 5 is provided on the bottom cover 52, and a one-way valve 53 is provided on the air inlet 521. The air outlet end of the air supply joint 8 is connected to the one-way valve 53 and is used to control the opening and closing of the one-way valve 53. When the gas cylinder 6 is opened to supply gas into the water bottle 5, the one-way valve 53 is opened under the action of the gas in the gas cylinder 6 so that the gas in the gas cylinder 6 enters the water bottle 5. When the gas cylinder 6 is closed, the one-way valve 53 is closed. The air supply joint 8 realizes the quick connection between the air supply pipe 9 of the gas cylinder 6 and the one-way valve 53; the setting of the one-way valve 53 makes the sparkling water in the water bottle 5 not flow out through the air inlet 521, but the gas in the gas cylinder 6 can enter the water bottle 5. The design is ingenious and the structure is simple.

[0063] As Figure 7 shown, an installation position 71 for the water bottle 5 is provided on the top surface of the base 7. The air supply joint 8 is disposed at a position corresponding to the installation position 71 in the base 7, and the air outlet end of the air supply joint 8 extends into the installation position 71. When the water bottle 5 is placed in the installation position 71, the air outlet end of the air supply joint 8 is inserted into the one-way valve 53 of the bottom cover 52. By providing the installation position 71, it is convenient to position the water bottle 5 on the base 7 and ensure the stability of the connection between the air supply joint 8 and the one-way valve 53. When the water bottle 5 is placed on the installation position 71 of the base 7, the water bottle 5 and the gas cylinder 6 are arranged in parallel.

[0064] In some embodiments, as Figure 7As shown, the one-way valve 53 includes a valve body 531 and a valve sleeve 532. A valve cavity (not shown in the figure) is provided inside the valve body 531. The outlet end of the gas supply joint 8 extends into the valve cavity and forms a seal with the inner cavity wall of the valve cavity. Specifically, the valve cavity penetrates to the bottom end of the valve body 531. The outlet end of the gas supply joint 8 extends in from the bottom end of the valve cavity, and a second sealing ring 81 is sleeved on the outlet end of the gas supply joint 8. The second sealing ring 81 is used to seal between the outer peripheral wall of the outlet end and the inner cavity wall of the valve cavity. The upper part of the valve body 531 forms an outlet end. An air outlet 533 communicating with the valve cavity is provided on the periphery of the outlet end. The valve sleeve 532 is sleeved on the outlet end and covers the air outlet 533. The outlet end extends into the air inlet 521, and a seal is formed between the valve sleeve 532 and the air inlet 521. When the gas cylinder 6 is opened to send gas into the valve cavity, the valve sleeve 532 deforms under the action of the gas and forms a gap with the outlet end, so that the air outlet 533 is opened. The gas coming out of the air outlet 533 enters the air inlet 521 and enters the water bottle 5 from the air inlet 521. When the gas cylinder 6 is closed and the gas supply to the gas supply joint 8 is stopped, the valve sleeve 532 resumes and tightly wraps around the outlet end of the valve body 531 to close the air outlet 533. At this time, the one-way valve 53 is closed, and no gas enters the water bottle 5, and the sparkling water in the water bottle 5 cannot flow out from the lower bottle mouth either.

[0065] The valve sleeve 532 can be made of, for example, silicone material so that it can elastically deform to control the opening or closing of the air outlet 533.

[0066] A nozzle 522 can be provided at one end of the air inlet 521 inside the water bottle 5 to facilitate injecting the gas in the gas cylinder 6 into the water in the gas cylinder 6.

[0067] The gas contained in the gas cylinder 6 can be high-pressure CO2. When the lever 61 at the top of the gas cylinder 6 is pressed downward, the lever 61 pushes the ejector rod 62 to move downward and opens the gas cylinder 6, releasing the high-pressure gas in the gas cylinder 6. The high-pressure gas in the gas cylinder 6 first enters the gas supply pipeline 9, and then sequentially enters the water bottle 5 through the gas supply joint 8 and the one-way valve 53. The high-pressure gas is carbonated with the drinking water in the water bottle 5. After the drinking water in the water bottle 5 is carbonated, the remaining gas in the water bottle 5 is discharged through the safety valve 54, and the water in the water bottle 5 forms soda water. See Figure 8 , and the arrow direction in the figure is the gas flow direction.

[0068] The above description is intended to be illustrative rather than restrictive. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present disclosure. Moreover, the above examples (or one or more of their solutions) can be used in combination with each other, and considering these embodiments, they can be combined with each other in various combinations or arrangements.
