Description

Water dispensing mechanism and aerated water machine Technical Field

[0001] This application belongs to the field of beverage equipment technology, and in particular relates to a water dispensing mechanism and a sparkling water machine. Background Technology

[0002] Currently, soda water makers on the market require the bottle cap to be removed before the soda water can be poured out. For example, the soda water maker with a concentrated fruit juice powder inkjet device disclosed in Chinese Patent No. CN 103720363 B requires the user to remove the gas inlet (equivalent to a bottle cap) from the pressure water bottle mouth before pouring out the soda water after it has been made. This operation is rather cumbersome and inconvenient for users.

[0003] Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the purpose of this application is to provide a water outlet mechanism that can make sparkling water flow out of a water bottle without removing the bottle cap, and a sparkling water machine having the water outlet mechanism.

[0005] The technical solution adopted in this application embodiment is a water dispensing mechanism for a water bottle containing sparkling water. The water dispensing mechanism includes a water dispensing pipe disposed inside the water bottle, and a water dispensing channel, a water outlet, and a pressing component disposed on the top cap or body of the water bottle. The water outlet is connected to the water dispensing channel.

[0006] The pressing component is movable relative to the water bottle and has a first position and a second position. When the pressing component is in the first position, it cuts off the connection between the water outlet channel and the water outlet pipe. When the pressing component is in the second position, it connects the water outlet channel and the water outlet pipe, and the sparkling water in the water bottle enters the water outlet pipe, the pressing component and the water outlet channel in sequence and flows out from the water outlet.

[0007] In an optional embodiment, the pressing assembly has a water chamber and an inlet and an outlet communicating with the water chamber. The inlet is connected to the upper end of the outlet pipe, allowing the sparkling water in the water bottle to enter the water chamber via the outlet pipe. When the pressing assembly is in the first position, the outlet is offset from the other end of the outlet channel, the communication between the outlet pipe and the outlet channel is cut off, and the sparkling water in the water bottle cannot enter the outlet channel. When the pressing assembly is in the second position, the outlet is opposite to the other end of the outlet channel, the outlet pipe is connected to the outlet channel, and the sparkling water in the water bottle can enter the outlet channel and flow out through the outlet. The pressing assembly has a reasonable structure, which facilitates the connection or disconnection (disconnection) of the outlet pipe and the outlet channel when switching between the first and second positions.

[0008] In an optional embodiment, the pressing assembly includes a main body, a pressing element, and a reset element;

[0009] The main body is fixed inside the bottle cap. The main body has a water cavity inside, which extends to the upper end of the main body to form an open end. The water inlet is located at the lower end of the main body. The side of the main body has an opening that communicates with the water cavity. The other end of the water outlet is connected to the opening.

[0010] The lower part of the pressing member extends into the water cavity through the opening of the main body and seals the opening. The lower part of the pressing member has a passage extending to its bottom end. The lower periphery of the pressing member has a water outlet hole communicating with the passage, and the periphery of the pressing member is sealed and fitted to the inner wall of the water cavity. The upper part of the pressing member extends out of the bottle cap to form a pressing part. When the pressing part is pressed, the lower part of the pressing member moves along the water cavity so that the water outlet hole is offset from or opposite to the water outlet channel.

[0011] The reset member is disposed between the main body and the pressing member, and is used to apply a force to the pressing member to reset it from the second position to the first position. The pressing assembly has a simple and reasonable structural principle, is convenient and quick to operate, and has low manufacturing cost.

[0012] In an optional embodiment, the main body is columnar, the water cavity extends along the axial direction of the main body, and the cross-section of the water cavity is circular; the lower end of the pressing member is hollow tubular and is adapted to the water cavity;

[0013] and / or

[0014] The lower part of the pressing component is fitted with first sealing rings located above and below the water outlet. This achieves a seal between the lower periphery of the pressing component and the inner wall of the water cavity, preventing leakage.

[0015] In an optional embodiment, the water inlet extends downward to form a connector that extends into the water bottle, and the upper end of the water outlet pipe is connected to the connector. This facilitates the connection between the water outlet pipe and the water inlet of the main body.

[0016] In an optional embodiment, the side of the bottle cap extends outward to form a protrusion, and the water outlet is provided on the downward-facing side of the free end of the protrusion. The water outlet channel extends from the bottle cap to the water outlet of the protrusion. This facilitates the arrangement of the water outlet channel and the water outlet.

[0017] In an optional embodiment, the bottom periphery of the pressing part extends outward to form a limiting structure; the bottle cap has a through hole, and the pressing part extends out of the bottle cap through the through hole. When the pressing part is in the first position, the limiting structure abuts against the lower periphery of the through hole. This prevents the pressing part from detaching from the bottle cap when resetting to the first position, improving the safety and reliability of the product.

[0018] A sparkling water machine includes a gas cylinder and a water bottle. The gas cylinder supplies gas to the water bottle to create sparkling water. The sparkling water machine also includes a water dispensing mechanism as described in any of the above embodiments, which is located on the top cap of the water bottle. This sparkling water machine can dispense sparkling water from the water bottle to the user without removing the top cap, thus improving user convenience.

[0019] In an optional embodiment, the sparkling water machine further includes a base, on which a gas supply connector is provided, and the gas inlet of the gas supply connector is connected to the gas cylinder through a gas supply pipe;

[0020] The water bottle has a bottom cap at its lower opening, and the bottom cap has an air inlet communicating with the inside of the water bottle. The air inlet is equipped with a one-way valve. The outlet of the air supply connector is connected to the one-way valve to control its opening and closing. When the gas cylinder is open to supply gas to the water bottle, the one-way valve opens under the action of the gas in the cylinder, allowing the gas to enter the water bottle. When the gas cylinder is closed, the one-way valve closes. The air supply connector enables a quick connection between the gas cylinder's supply pipe and the one-way valve; the one-way valve allows gas from the cylinder to enter the water bottle, but prevents the carbonated water in the water bottle from flowing out through the air inlet.

[0021] In an optional embodiment, the one-way valve includes a valve body and a valve sleeve;

[0022] The valve body has a valve cavity, the air outlet of the air supply connector extends into the valve cavity and forms a seal with the inner wall of the valve cavity, the upper part of the valve body forms an air outlet, and the circumference of the air outlet is provided with an air outlet.

[0023] The valve sleeve is fitted onto the outlet end and seals the outlet port. The outlet end extends into the inlet port, and the valve sleeve seals the inlet port. When the gas cylinder is opened to supply gas into the valve chamber, the valve sleeve deforms under the action of the gas to open the outlet port. The one-way valve has a simple structure and good performance.

[0024] Compared with the prior art, the beneficial effects of the embodiments of this application are as follows: the water dispensing mechanism of this application can control the flow of sparkling water in the water bottle, eliminating the need for the user to remove the bottle cap to pour out the sparkling water when they need to drink it, thus improving the convenience of use.

Detailed Implementation

[0036] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0038] To keep the following description of the embodiments of this application clear and concise, detailed descriptions of known functions and known components are omitted.

[0039] As shown in Figures 1 and 3, this application embodiment provides a water dispensing mechanism, for example, for use in a water bottle 5 for making soda water. It is understood that the water bottle 5 can contain other beverages with bubbly properties besides soda water, meaning the pressure inside the water bottle 5 is slightly higher than the external atmospheric pressure. For ease of description, soda water and other beverages with bubbly properties will be collectively referred to as sparkling water below.

[0040] The water dispensing mechanism includes a water dispensing pipe 3 located inside the water bottle 5, and a water dispensing channel 1, a water outlet 2, and a pressing component 4, all located on the bottle cap 51 or the body of the water bottle 5. The water outlet 2 is connected to the water dispensing channel 1. The pressing component 4 is movable relative to the water bottle 5 and has a first position and a second position. When the pressing component 4 is in the first position, it cuts off the connection between the water dispensing channel 1 and the water dispensing pipe 3. When the pressing component 4 is in the second position, it connects the water dispensing channel 1 and the water dispensing pipe 3, and the sparkling water in the water bottle 5 sequentially enters the water dispensing pipe 3, the pressing component 4, and the water dispensing channel 1 and flows out from the water outlet 2.

[0041] It is understood that the water dispensing mechanism of this application can be located either at the mouth of the water bottle 5 or at the top of the body of the water bottle 5. When the water dispensing mechanism is located at the mouth, all components constituting the water dispensing mechanism are located on the bottle top cap 51. When the water dispensing mechanism is located on the body of the bottle, a through-hole communicating with the inside of the water bottle 5 needs to be opened on the body of the bottle, and the through-hole is located above the liquid level inside the water bottle 5. A sealing cap is installed at the through-hole, and all components constituting the water dispensing mechanism are located on the sealing cap. The following will provide a detailed description using the example of the water dispensing mechanism being located on the bottle top cap 51.

[0042] As shown in Figures 2 and 4, the water dispensing mechanism includes a water dispensing channel 1, a water outlet 2, a water dispensing pipe 3, and a pressing component 4. The water dispensing channel 1 is located on the bottle cap 51; the water outlet 2 is located on the bottle cap 51 and connected to one end of the water dispensing channel 1, or the water outlet 2 extends from one end of the water dispensing channel 1 to the periphery or bottom of the bottle cap 51, allowing the carbonated water in the water dispensing channel 1 to flow out through the water outlet 2 and be supplied to the user. The water dispensing pipe 3 is located inside the water bottle 5, with its lower end extending below the water surface and its upper end positioned near the bottle cap 51. To ensure all the carbonated water in the water bottle 5 flows out and avoids waste, the lower end of the water dispensing pipe 3 can extend to the bottom of the water bottle 5. The pressing component 4 is located on the bottle cap 51 and between the other end of the water outlet channel 1 and the upper end of the water outlet pipe 3. It is used to cut off or open the connection between the water outlet pipe 3 and the water outlet channel 1. That is, the pressing component 4 can connect or disconnect the other end of the water outlet channel 1 with the upper end of the water outlet pipe 3. The pressing component 4 can move relative to the bottle cap 51 and has a first position and a second position. When the pressing component 4 is in the first position, it cuts off the connection between the water outlet channel 1 and the water outlet pipe 3, that is, the bubble water in the water outlet pipe 3 cannot enter the water outlet channel 1. When the pressing component 4 is in the second position, it connects the water outlet channel 1 and the water outlet pipe 3, and allows the bubble water in the water bottle 5 to sequentially enter the water outlet pipe 3, the pressing component 4, and the water outlet channel 1 and flow out from the water outlet 2.

[0043] The water dispensing mechanism of this embodiment can control the sparkling water in the water bottle 5 to enter the water dispensing channel 1 and flow out from the water outlet 2 through 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 made to flow out directly by operating the pressing component 4, without having to remove the bottle cap 51 to pour out the sparkling water by tilting the water bottle 5, which improves the convenience of use and provides a better user experience.

[0044] In some embodiments, continuing with Figures 2 and 4, the pressing assembly 4 has a water cavity 411 and an inlet 412 and an outlet 4211 communicating with the water cavity 411. The inlet 412 is connected to the upper end of the outlet pipe 3, so that the sparkling water in the water bottle 5 can enter the water cavity 411 through the outlet pipe 3. When the pressing assembly 4 is in the first position, the outlet 4211 is offset from the other end of the outlet channel 1, the communication between the outlet pipe 3 and the outlet channel 1 is cut off, and the sparkling water in the water bottle 5 cannot enter the outlet channel 1. When the pressing assembly 4 is in the second position, the outlet 4211 is opposite to the other end of the outlet channel 1, the outlet pipe 3 is connected to the outlet channel 1, and the sparkling water in the water bottle 5 can enter the outlet channel 1 and flow out from the outlet 2. The pressing assembly 4 has a reasonable structure, which facilitates the connection or disconnection (disconnection) of the outlet pipe 3 and the outlet channel 1 when switching between the first and second positions.

[0045] As shown in Figures 2 and 4, the pressing assembly 4 includes a main body 41, a pressing element 42, and a resetting element 423. The main body 41 is fixed inside the bottle cap 51. A water cavity 411 is provided inside the main body 41, which extends to the upper end of the main body 41 to form an open end. A water inlet 412 is located at the lower end of the main body 41. An opening 413 communicating with the water cavity 411 is provided on the side of the main body 41. 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 sealed at the connection point, so that the bubble water in the water cavity 411 can only enter the water outlet channel 1 and will not leak out.

[0046] The lower part 421 of the pressing member 42 extends into the water cavity 411 through the opening of the main body 41 and seals the opening to prevent the bubble water in the water cavity 411 from leaking through the opening. The lower part 421 of the pressing member 42 has a passage 4212 extending to its bottom end, and the periphery of the lower part 421 of the pressing member 42 has a water outlet 4211 communicating with the passage 4212, and the periphery of the pressing member 42 is sealed and fitted against the inner wall of the water cavity 411. The upper part of the pressing member 42 extends out of the bottle cap 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, causing the pressing member 42 to switch from a first position to a second position, and the water outlet 4211 and the other end of the water outlet channel 1 change from being initially offset to being opposite each other. The term "relative" here does not mean that the water outlet 4211 and the other end of the water outlet channel 1 are completely aligned, but also includes that only a part of them are aligned. When the two are only partially aligned, it is necessary to ensure that the air bubbles in the water cavity 411 can enter the water outlet channel 1 through the water outlet 4211.

[0047] 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 4211 and the other end of the water outlet channel 1 are changed from relative to offset.

[0048] The pressing component 42 of this application can switch from a first position to a second position under the action of external force, and automatically reset to the initial state of the first position under the action of the reset component 423 when the pressing is released. Furthermore, the connection or disconnection between the water outlet pipe 3 and the water outlet channel 1 is realized through pressing and automatic reset. The structure and principle are simple and reasonable, the operation is convenient and quick, and the manufacturing cost is low.

[0049] When the pressing part 42 is not pressed, it is in the first position, and the water outlet 4211 is misaligned with the other end of the water outlet channel 1. The sparkling water in the water bottle 5 cannot enter the water outlet channel 1 through the water outlet pipe 3, as shown in Figure 2. When the user needs to drink sparkling water, the pressing part 422 is pressed down, and the pressing part 42 moves downward. When the pressing part 42 moves to the second position, the water outlet 4211 is opposite to the other end of the water outlet channel 1 and is connected. During the process of pressing the pressing part 42 downward, pressure is applied to the water in the water bottle 5. When the water outlet 4211 is opposite to the other end of the water outlet channel 1 and the water outlet pipe 3 is connected to the water outlet channel 1, the sparkling 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, as shown in Figure 3. The black dots in Figures 3 and 4 represent flowing sparkling water. Once the amount of bubble water dispensed reaches the user's desired level, the pressing part 422 is released. Under the action of the resetting part 423, the pressing part 42 is reset upward to the first position, ready for the user's next use.

[0050] As shown in Figures 2 and 4, the main body 41 is columnar and vertically arranged, and the water cavity 411 extends along the axial direction of the main body 41, with a circular cross-section. The lower part 421 of the pressing member 42 is a hollow tube and is adapted to fit the water cavity 411. The lower part 421 of the pressing member 42 is fitted with first sealing rings 425 located above and below the water outlet 4211, respectively, to seal the upper and lower sides of the water outlet 4211. In this way, the periphery of the lower part 421 of the pressing member 42 is sealed with the inner wall of the water cavity 411, so that the air bubbles in the water cavity 411 can only enter the water outlet channel 1 without leakage.

[0051] The specific structure of the reset member 423 is not limited, as long as it can provide the pressing member 42 with a force to reset it from the second position to the first position. As shown in Figures 2 and 4, 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 limits the spring to prevent it from shaking. The lower end of the spring abuts against the bottom of the water cavity 411. When the pressing part 422 presses down, causing the pressing member 42 to switch from the first position to the second position, the spring is compressed and accumulates elastic potential energy. When the force acting on the pressing part 422 is removed, 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.

[0052] In some embodiments, continuing with Figures 2 and 4, the 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 outlet pipe 3 is connected to the connector 424. By providing the connector 424, it is convenient to connect the outlet pipe 3 to the inlet 412 of the main body 41.

[0053] As shown in Figures 2 and 4, the side of the bottle cap 51 extends outward to form a protrusion 514. A water outlet 2 is located on the downward-facing side of the free end of the protrusion 514. The water outlet channel 1 extends from inside the bottle cap 51 to the water outlet 2 of the protrusion 514. By designing the protrusion 514 on the bottle cap 51, sufficient space is provided for the water outlet channel 1, and it is also convenient to design the water outlet 2 to face downwards, making it easier for users to collect water.

[0054] In some embodiments, as shown in Figures 2 and 4, the bottom periphery of the pressing part 422 extends outward to form a limiting structure 4221, which can be annular or discontinuous flange. The bottle cap 51 has a through hole (not shown, as it is obscured by the pressing part 422), through which the pressing part 422 extends out of the bottle cap 51. When the pressing part 42 is in the first position, the limiting structure 4221 abuts against the lower periphery of the through hole. By providing the limiting structure 4221, the pressing part 42 is prevented from dislodging from the bottle cap 51 when it resets to the first position under the action of the resetting member 423, and the pressing part 42 is precisely positioned in the first position.

[0055] This application also provides a sparkling water machine. As shown in Figures 5, 6, and 8, the sparkling water machine includes a water bottle 5 and a gas cylinder 6. The gas cylinder 6 supplies gas to the water bottle 5 to form sparkling water. The sparkling water machine also includes the water dispensing mechanism described in any of the above embodiments, which is located on the bottle cap 51 of the water bottle 5. This sparkling water machine can dispense sparkling water from the water bottle 5 to the user without removing the bottle cap 51, thus improving user convenience by eliminating the need to lift the water bottle 5 to empty the sparkling water.

[0056] As shown in Figures 2 and 4, the bottle cap 51 includes an inner cap 511 and an outer cap 512. The inner cap 511 seals the upper bottle opening, forming a seal. The outer cap 512 covers the inner cap 511, forming a cavity 513 between the inner cap 511 and the outer cap 512. A protrusion 514 extends laterally outward from the side of the outer cap 512 and is a hollow structure, communicating with the cavity 513. A water outlet channel 1 is located within the hollow structure and the cavity 513. The main body 41 of the pressing assembly 4 is fixed within the cavity 513, and the connector 424 at the bottom end of the main body 41 extends through the inner cap 511 into the water bottle 5. A through hole is located on the portion of the outer cap 512 corresponding to the top end of the main body 41.

[0057] In some embodiments, as shown in Figures 5 and 6, the sparkling water machine further includes a base 7. The base 7 has a gas supply connector 8 extending from its top surface. The inlet end of the gas supply connector 8 is connected to the gas cylinder 6 via a gas supply pipe 9 (see Figure 8). As shown in Figure 7, the lower opening of the water bottle 5 has a bottle bottom cap 52. The bottle bottom cap 52 has an air inlet 521 communicating with the inside of the water bottle 5, and a one-way valve 53 is provided on the air inlet 521. The outlet end of the gas supply connector 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 to the water bottle 5, the one-way valve 53 opens under the action of the gas in the gas cylinder 6, allowing the gas in the gas cylinder 6 to enter the water bottle 5. When the gas cylinder 6 is closed, the one-way valve 53 closes. The gas supply connector 8 enables a quick connection between the gas supply pipe 9 of the gas cylinder 6 and the one-way valve 53. The one-way valve 53 prevents the carbonated water in the water bottle 5 from flowing out through the air inlet 521, but allows the gas in the gas cylinder 6 to enter the water bottle 5. The design is ingenious and the structure is simple.

[0058] As shown in Figure 7, the top surface of the base 7 has a mounting position 71 for the water bottle 5. The gas supply connector 8 is located at the corresponding mounting position 71 within the base 7, with its outlet extending into the mounting position 71. When the water bottle 5 is placed in the mounting position 71, the outlet of the gas supply connector 8 is inserted into the one-way valve 53 of the bottle bottom cap 52. The mounting position 71 facilitates the positioning of the water bottle 5 on the base 7, ensuring the stability of the connection between the gas supply connector 8 and the one-way valve 53. When the water bottle 5 is placed in the mounting position 71 of the base 7, the water bottle 5 and the gas cylinder 6 are arranged side-by-side.

[0059] In some embodiments, as shown in FIG7, 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 air supply connector 8 extends into the valve cavity and forms a seal with the inner wall of the valve cavity. Specifically, the valve cavity extends to the bottom end of the valve body 531, the outlet end of the air supply connector 8 extends into the valve cavity from the bottom end, and a second sealing ring 81 is fitted on the outlet end of the air supply connector 8. The second sealing ring 81 is used to seal the outer peripheral wall of the outlet end and the inner wall of the valve cavity. An outlet end is formed at the upper part of the valve body 531, and an outlet port 533 communicating with the valve cavity is provided on the periphery of the outlet end. The valve sleeve 532 is fitted onto the outlet end and covers the outlet port 533. The outlet end extends into the inlet port 521, and a seal is formed between the valve sleeve 532 and the inlet port 521. When gas cylinder 6 is opened to supply gas into the valve chamber, the valve sleeve 532 deforms under the action of the gas, creating a gap between itself and the outlet end, thereby opening the outlet 533. The gas exiting from the outlet 533 enters the inlet 521 and then enters the water bottle 5 through the inlet 521. When gas cylinder 6 is closed and the gas supply to the gas connector 8 is stopped, the valve sleeve 532 returns to its original position and tightly wraps around the outlet end of the valve body 531, thus closing the outlet 533. At this time, the one-way valve 53 is closed, so no gas enters the water bottle 5, and the bubble water in the water bottle 5 cannot flow out from the lower bottle opening.

[0060] The valve sleeve 532 may be made of, for example, silicone material, so that it can elastically deform to control the opening or closing of the air outlet 533.

[0061] The air inlet 521 is located at one end inside the water bottle 5 and a nozzle 522 can be installed to facilitate the injection of gas from the gas bottle 6 into the water inside the gas bottle 6.

[0062] The gas cylinder 6 contains high-pressure CO2. When the pressure rod 61 on the top of the gas cylinder 6 is pressed down, the pressure rod 61 pushes the top rod 62 downward and opens the gas cylinder 6, releasing the high-pressure gas inside. The high-pressure gas in the gas cylinder 6 first enters the gas supply pipe 9, and then enters the water bottle 5 through the gas supply connector 8 and the one-way valve 53 in sequence. The high-pressure gas carbonates the drinking water in the water bottle 5. After the drinking water in the water bottle 5 has been carbonated, the remaining gas in the water bottle 5 is discharged through the safety valve 54, and the water in the water bottle 5 becomes soda water. See Figure 8, where the arrows indicate the direction of gas flow.

[0063] The above description is intended to be illustrative and not restrictive. Those skilled in the art can make variations, modifications, substitutions, and alterations to the above embodiments within the scope of this disclosure. Moreover, the above examples (or one or more of them) can be used in combination with each other, and these embodiments can be combined with each other in various combinations or arrangements.
