Description

Technical Field

[0001] The present invention relates to the technical field of beverage preparation, and particularly to a device for preparing sparkling water. Background Art

[0002] Existing sparkling water machines generally add gas to water by manual pressing, and only a certain amount of gas can be added. However, manual control of foaming is very inconvenient for users to operate and is not conducive to accurately controlling the amount of gas added to water. For example, a Chinese patent with the publication number CN114916826A discloses a portable sparkling water machine. It drives a slider to slide along a chute by clockwise rotating an upper cover, and then pushes a rotating seat to move downward, further squeezing a storage bin and a gas cylinder downward, so that the gas cylinder is punctured by a puncturing thimble. The carbon dioxide gas in the gas cylinder passes through the puncturing thimble and an air inlet rod to a water bottle filled with water to realize the production of sparkling water. It can be seen that the preparation of this portable sparkling water machine requires manual rotation by the user and can only add a certain amount of gas to water. Users cannot adjust the amount of gas added to water according to their preferences, that is, it cannot meet the different requirements of different users for the taste of sparkling water. Summary of the Invention

[0003] In view of the above technical problems existing in the prior art, the present application provides a device for preparing sparkling water. By controlling the opening and closing of a first pump body and a first valve body through a control device, it can accurately control the amount of gas provided to a preparation bottle via a gas cylinder assembly to meet the different requirements of different users for the taste of sparkling water, and can realize automatic foaming, which is convenient for users to operate.

[0004] An embodiment of the present invention provides a device for preparing sparkling water, including a preparation bottle and a water purification tank for supplying water to the preparation bottle, and further including:

[0005] A first pump body, which is connected to the water purification tank through a first pipeline and is used to pump water from an external water source into the water purification tank;

[0006] A gas cylinder assembly, which includes a bottle body and a switch assembly provided at the bottle mouth of the bottle body. The air outlet of the bottle body is connected to the preparation bottle and is used to supply gas to the preparation bottle when the switch assembly is opened. The switch assembly has a hydraulic chamber, and the switch assembly is opened when a preset volume of solution is contained in the hydraulic chamber;

[0007] A first valve body, which is provided on the first pipeline. A second pipeline is connected upstream of the first valve body on the first pipeline, and the second pipeline is connected to the hydraulic chamber of the switch assembly;

[0008] A control device, which is electrically connected to the first pump body and the first valve body. The control device is used to send a first control instruction to turn on both the first pump body and the first valve body, so as to supply water to the water purification tank through the first pipeline. It is also used to send a second control instruction to turn on the first pump body and turn off the first valve body, so as to supply water to the hydraulic chamber through the first pipeline and the second pipeline, thereby opening the switch assembly to supply gas to the preparation bottle. The above-mentioned sparkling water preparation device can accurately control the amount of gas provided to the preparation bottle via the gas cylinder assembly by controlling the opening and closing of the first pump body and the first valve body by the control device, so as to meet the different requirements of different users for the taste of sparkling water, and can realize automatic inflation, which is convenient for users to operate.

[0009] In some embodiments, the sparkling water preparation device further includes a second valve body, which is connected to the air outlet of the preparation bottle and connected to the water purification tank through a third pipeline. When the air pressure in the preparation bottle exceeds a first preset threshold, the gas in the preparation bottle is discharged to the water purification tank through the second valve body. By setting the second valve body, the air pressure in the preparation bottle can be prevented from being too high, achieving the purpose of improving product safety.

[0010] In some embodiments, one end of the third pipeline for connecting the water purification tank is connected to the first pipeline, and the connection point of this end and the first pipeline is located upstream of the first valve body, so that the second valve body discharges gas through the third pipeline and the first pipeline. In this way, the first pipeline can not only intake water but also exhaust gas, achieving the purpose of reasonable pipeline connection layout.

[0011] In some embodiments, the sparkling water preparation device further includes a first pressure relief valve, which is respectively communicated with the preparation bottle and the water purification tank, and is used to discharge the gas in the preparation bottle to the water purification tank when the air pressure in the preparation bottle exceeds a second preset threshold. In this way, the product safety can be further improved by setting the first pressure relief valve, avoiding the situation that the excessive air pressure in the preparation bottle cannot be reduced when the second valve body fails.

[0012] In some embodiments, the sparkling water preparation device further includes a second pressure relief valve provided on the third pipeline. The second valve body is specifically a one-way valve. The second pressure relief valve is used to open when the air pressure in the preparation bottle exceeds the first preset threshold, so as to discharge the gas in the preparation bottle to the water purification tank. By setting the second pressure relief valve, the safety of the preparation bottle can be further ensured, avoiding potential safety hazards caused by excessive air pressure in the preparation bottle.

[0013] In some embodiments, the sparkling water preparation device further includes a third pressure relief valve, which is respectively communicated with the air outlet of the bottle body, the air inlet of the preparation bottle, and the water purification tank, and is used to open when the air pressure in the bottle body and / or the preparation bottle exceeds a third preset threshold, so as to discharge the gas in the bottle body and / or the preparation bottle into the water purification tank. By setting the third pressure relief valve, the safety of the bottle body and the preparation bottle can be further ensured, and potential safety hazards caused by excessive air pressure in the bottle body and / or the preparation bottle can be avoided.

[0014] In some embodiments, the sparkling water preparation device further includes a third valve body and a water outlet nozzle. The third valve body is respectively communicated with the water outlet nozzle and the preparation bottle, and the third valve body is electrically connected to the control device. The control device is further configured to send a third control instruction to open the third valve body after the water in the water purification tank and the gas in the bottle body are mixed in the preparation bottle, so that under the action of the pressure in the preparation bottle, the bubble water in the preparation bottle flows to the water outlet nozzle. In this way, the bubble water can directly flow to the water outlet nozzle under the pressure in the preparation bottle, without the user manually pouring out the bubble water in the preparation bottle, and has the function of automatically discharging the bubble water.

[0015] In some embodiments, the sparkling water preparation device further includes a fourth valve body, which is arranged on the first pipeline or the second pipeline. When the fourth valve body is arranged on the first pipeline, the fourth valve body is arranged upstream of the first valve body, and the fourth valve body enables the water in the pipeline to flow unidirectionally to the downstream of the fourth valve body. The above structural layout is reasonable and is conducive to defining the water flow direction.

[0016] In some embodiments, the sparkling water preparation device further includes a fifth valve body. Both the fourth valve body and the fifth valve body are arranged on the first pipeline. The fifth valve body is located downstream of the fourth valve body and upstream of the first valve body. The control device is further configured to send a fourth control instruction to open the first valve body after sending the second control instruction, so that the water in the hydraulic cavity flows through the fifth valve body and the first valve body into the water purification tank. In this way, the water in the hydraulic cavity can be discharged into the water purification tank by controlling the opening of the first valve body, so that the switch assembly is switched from the open state to the closed state, and the air outlet volume of the bottle body can be accurately controlled.

[0017] In some embodiments, the sparkling water preparation device further includes a sixth valve body, which is respectively connected to the second pipeline and the third pipeline. The control device is further configured to send a fourth control instruction to turn off the first pump body after sending the second control instruction, so that the water in the hydraulic chamber flows into the water purification tank through the sixth valve body and the second pressure relief valve. In this way, the water in the hydraulic chamber can be discharged into the water purification tank by controlling the first pump body to turn off, and the switch assembly can be switched from the open state to the closed state, realizing precise control of the gas outlet volume of the bottle body.

[0018] Compared with the prior art, the beneficial effects of the embodiments of the present application are as follows: By sending a first control instruction through the control device, the first pump body and the first valve body can be opened to supply water to the water purification tank. By sending a second control instruction through the control device, the first pump body can be opened and the first valve body can be closed, so that water does not supply water to the water purification tank through the first pipeline, but supplies water to the hydraulic chamber through the first pipeline and the second pipeline. After the water in the hydraulic chamber reaches the preset volume, the switch assembly at the gas outlet of the bottle body of the gas cylinder assembly opens, so that the gas cylinder assembly can supply gas to the preparation bottle, enabling water and gas to be fully mixed in the preparation bottle to form sparkling water. In this way, by controlling the opening and closing of the first pump body and the first valve body through the control device, the amount of gas provided to the preparation bottle by the gas cylinder assembly can be precisely controlled to meet the different requirements of different users for the taste of sparkling water, and automatic inflation can be realized, which is convenient for users to operate.

Detailed implementation manners

[0028] To enable those skilled in the art to better understand the technical solutions of the present application, the present application will be described in detail below with reference to the accompanying drawings and specific implementation manners.

[0029] The embodiment of the present invention provides a bubble water preparation device. As Figures 1 to 4 shown, the bubble water preparation device includes a preparation bottle 1 and a clean water tank 2 for supplying water to the preparation bottle 1. It further includes a first pump body 3, a gas cylinder assembly 5, a first valve body 6, and a control device. The first pump body 3 is connected to the clean water tank 2 through a first pipeline 4 and is used to pump the water from an external water source into the clean water tank 2. The gas cylinder assembly 5 includes a bottle body 501 and a switch assembly 502 provided at the bottle mouth of the bottle body 501. The gas outlet 504 of the bottle body 501 is connected to the preparation bottle 1 and is used to supply gas to the preparation bottle 1 when the switch assembly 502 is opened. The switch assembly 502 has a hydraulic chamber 503, and the switch assembly 502 is opened when a preset volume of solution is contained in the hydraulic chamber 503. The first valve body 6 is provided on the first pipeline 4, and a second pipeline 7 is connected upstream of the first valve body 6 on the first pipeline 4. The second pipeline 7 is connected to the hydraulic chamber 503 of the switch assembly 502.

[0030] Further, the control device is electrically connected to the first pump body 3 and the first valve body 6. The control device is configured to send a first control instruction to turn on both the first pump body 3 and the first valve body 6, so as to supply water to the water purification tank 2 through the first pipeline 4, and is further configured to send a second control instruction to turn on the first pump body 3 and turn off the first valve body 6, so as to supply water to the hydraulic chamber 503 through the first pipeline 4 and the second pipeline 7, thereby opening the switch assembly 502 to supply gas to the preparation bottle 1. Among them, the first pump body 3 may specifically be a booster pump.

[0031] Specifically, it can be combined with Figures 1 to 4 , Figure 1 and Figure 2 is the structural block diagram of the bubble water preparation device in Embodiment 1, Figure 3 and Figure 4 is the structural block diagram of the bubble water preparation device in Embodiment 2; among them, Figure 1 and Figure 3 The direction of the arrow shown in is the liquid flow direction, that is, the flow direction of liquids such as water and bubble water, Figure 2 and Figure 4 The direction of the arrow shown in is the gas flow direction.

[0032] Specifically, the above-mentioned preparation bottle 1 can be understood as a container for preparing bubble water. The water in the water purification tank 2 and the gas in the bottle body 501 of the gas cylinder assembly 5 are both discharged into the preparation bottle 1 and are fully mixed in the preparation bottle 1 to prepare bubble water that meets the taste requirements of users.

[0033] Specifically, the second control instruction is used to control the first pump body 3 to be turned on for 2 to 4 seconds, that is, to inflate the preparation bottle 1 through the gas cylinder assembly 5 for 2 to 4 seconds. The user can adjust the opening time of the first pump body 3 controlled by the above-mentioned second control instruction according to the requirement of the inflation volume to prepare bubble water that meets the taste requirements.

[0034] Specifically, as Figures 1 to 4 shown, the bubble water preparation device may further include a seventh valve body 18 provided at the water inlet of the first pump body 3 and a filter 19 provided at the water outlet of the first pump body 3. The seventh valve body 18 can be electrically connected to the control device, and whether the external water source is connected to the first pump body 3 can be controlled by controlling the opening and closing of the seventh valve body 18. The above-mentioned filter 19 may have a purified water outlet and a concentrated water outlet. The purified water outlet is connected to the first pipeline 4 to provide purified water for the water purification tank 2, and the concentrated water outlet is connected to the concentrated water drain valve 20 to discharge the concentrated water formed by filtration through the concentrated water drain valve 20.

[0035] Specifically, as Figure 5 and Figure 6 shown, Figure 5 The air outlet 504 of the bottle body 501 shown in is in a closed state,Figure 6 The gas outlet 504 of the bottle body 501 is shown in an open state. Figure 6 The arrow direction shown in is the flow direction of the gas. The switch assembly 502 may include an elastic sleeve 505 and an upper cover, the upper end of the elastic sleeve 505 is open, the upper cover can be covered on the upper opening of the elastic sleeve 505, and the upper cover and the elastic sleeve 505 are surrounded to form the above-mentioned hydraulic chamber 503. The above-mentioned switch assembly 502 may also include a movable plate 506 and a piston member 507 that can perform piston movement under the action of the movable plate 506, and the piston member 507 is used to block or release the gas outlet 504 of the bottle body 501. After the hydraulic chamber 503 is filled with a preset volume of water, the elastic sleeve 505 can expand to drive the movable plate 506 to press against the piston member 507, so that the piston member 507 moves to open the gas outlet 504 of the bottle body 501. By setting the piston member 507, the gas outlet 504 of the bottle body 501 can be stably reciprocated and blocked or released, and the above-mentioned structure is compact and has stable transmission.

[0036] Specifically, the first valve body 6 can be understood as a normally open electromagnetic valve. When the gas outlet 504 of the bottle body 501 needs to be opened, the first valve body 6 is controlled to be closed by the control device, so that the water in the first pipe 4 cannot flow to the clean water tank 2 through the first valve body 6, but the second pipe 7 connected to the first pipe 4 supplies water to the hydraulic chamber 503, so that the water in the hydraulic chamber 503 reaches a preset volume, thereby opening the switch assembly 502, so that the gas can be discharged from the bottle body 501 to the preparation bottle 1. It should be noted that when the first valve body 6 on the first pipe 4 is in an open state, since the first pipe 4 and the clean water tank 2 are connected, the water in the first pipe 4 will be preferentially discharged from the first pipe 4 to the clean water tank 2, and will not be discharged to the hydraulic chamber 503 through the second pipe 7, that is, when the first valve body 6 is opened, the water will not flow to the hydraulic chamber 503, and even if a small amount of water flows to the hydraulic chamber 503, this small amount of water is not enough to open the switch assembly 502.

[0037] Specifically, the water outlet of the above-mentioned water purification tank 2 can be connected to a refrigerator 21 to cool the water through the refrigerator 21, so that the water provided to the preparation bottle 1 is water cooled by the refrigerator 21. The mixing of low-temperature water and gas can increase the dissolution rate of the gas, thereby achieving the purpose of preparing sparkling water with better taste.

[0038] Specifically, the bubble water preparation device may further include a second pump body 22 and an eighth valve body 23, wherein the second pump body 22 is connected to the water outlet of the refrigerator 21, and the second pump body 22 is electrically connected to the control device, and the control device is also used to control the second pump body 22 to open, so as to pump the cold water discharged from the refrigerator 21 into the preparation bottle 1. The eighth valve body 23 is arranged on the pipeline connecting the second pump body 22 and the preparation bottle 1, and the eighth valve body 23 may be a one-way valve to prevent the liquid in the preparation bottle 1 from flowing back into the refrigerator 21. Among them, the second pump body 22 may be a water pump.

[0039] Specifically, the above-mentioned sparkling water preparation device may further include a water level sensor disposed in the preparation bottle 1. The water level sensor is electrically connected to the control device. The water level sensor is used to detect the water level information in the preparation bottle 1. The control device may also be configured to obtain the water level information and send an instruction to stop the water supply from the water purification tank 2 to the preparation bottle 1 when the water level in the preparation bottle 1 reaches a preset water level.

[0040] In this application, by sending a first control instruction through the control device, the water purification tank 2 can be supplied with water by turning on the first pump body 3 and the first valve body 6. Also, by sending a second control instruction through the control device, the water will not be supplied to the water purification tank 2 through the first pipeline 4 by turning on the first pump body 3 and closing the first valve body 6, but will be supplied to the hydraulic chamber 503 through the first pipeline 4 and the second pipeline 7. After the water in the hydraulic chamber 503 reaches a preset volume, the switch assembly 502 at the air outlet 504 of the bottle body 501 of the gas cylinder assembly 5 is opened, so that the gas cylinder assembly 5 can supply gas to the preparation bottle 1, enabling the water and gas to be fully mixed in the preparation bottle 1 to form sparkling water. Thus, by controlling the opening and closing of the first pump body 3 and the first valve body 6 through the control device, the amount of gas supplied to the preparation bottle 1 via the gas cylinder assembly 5 can be accurately controlled to meet the different requirements of different users for the taste of sparkling water, and automatic air injection can be achieved, facilitating user operation.

[0041] In some embodiments, as Figures 1 to 4 shown, the above-mentioned sparkling water preparation device further includes a second valve body 8. The second valve body 8 is connected to the air outlet of the preparation bottle 1 and is connected to the water purification tank 2 through a third pipeline 9. When the air pressure in the preparation bottle 1 exceeds a first preset threshold, the gas in the preparation bottle 1 is discharged to the water purification tank 2 through the second valve body 8. By providing the second valve body 8, the air pressure in the preparation bottle 1 can be prevented from being too high, achieving the purpose of improving product safety.

[0042] Specifically, the above-mentioned second valve body 8 may specifically be a one-way valve, so that when the air pressure in the preparation bottle 1 exceeds the first preset threshold, the gas can be directly discharged through the second valve body 8, preventing the pressure of the pipeline connected to the second valve body 8 from acting on the preparation bottle 1 through the second valve body 8 and affecting the preparation of sparkling water.

[0043] Specifically, the above-mentioned second valve body 8 may be understood as not discharging the gas in the preparation bottle 1 when the gas in the preparation bottle 1 exceeds the atmospheric pressure, but discharging the gas when the air pressure in the preparation bottle 1 reaches the first preset threshold. Exemplarily, as Figure 2 shown, the second valve body 8 of the sparkling water preparation device in Embodiment 1 is opened when the air pressure in the preparation bottle 1 exceeds 0.2 MPa, so as to discharge the gas in the preparation bottle 1 to the water purification tank 2.

[0044] Specifically, the above-mentioned clean water tank 2 can be understood as a box body communicating with the atmosphere, and discharging gas into the clean water tank 2 will not affect the air pressure inside the clean water tank 2.

[0045] In some embodiments, such as Figure 1 and Figure 2 As shown, the third pipeline 9 of the first embodiment of the sparkling water preparation device is used to connect one end of the clean water tank 2 to the first pipeline 4, and the connection point of this end to the first pipeline 4 is located upstream of the first valve body 6, so that the second valve body 8 discharges gas through the third pipeline 9 and the first pipeline 4. In this way, the first pipeline 4 can not only let water in but also exhaust gas, achieving the purpose of a reasonable pipeline connection layout.

[0046] Specifically, after supplying gas to the preparation bottle 1 through the bottle body 501, the first valve body 6 can be controlled to open in a timely manner through the control device, so that when the air pressure in the preparation bottle 1 exceeds the first preset threshold, the gas in the preparation bottle 1 can be discharged into the clean water tank 2 in a timely manner through the second valve body 8, the third pipeline 9, the first valve body 6 and the first pipeline 4.

[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the first embodiment of the sparkling water preparation device further includes a first pressure relief valve 10, which is respectively communicated with the preparation bottle 1 and the clean water tank 2, and is used to discharge the gas in the preparation bottle 1 into the clean water tank 2 when the air pressure in the preparation bottle 1 exceeds the second preset threshold. In this way, the product safety can be further improved by setting the first pressure relief valve 10, avoiding the situation where the excessive air pressure in the preparation bottle 1 cannot be reduced when the second valve body 8 fails.

[0048] Specifically, the above-mentioned first pressure relief valve 10 can be configured to open when the air pressure in the preparation bottle 1 exceeds 0.6 MPa, that is, the above-mentioned second preset threshold can be 0.6 MPa, so as to achieve the purpose of pressure relief at high pressure.

[0049] Specifically, the air outlet of the above-mentioned first pressure relief valve 10 can be connected to the first pipeline 4 to discharge the gas into the clean water tank 2 through the first pipeline 4. The connection point of the first pressure relief valve 10 and the first pipeline 4 is located downstream of the first valve body 6.

[0050] In some embodiments, such as Figure 3 and Figure 4As shown, the bubble water preparation device of the second embodiment further includes a second pressure relief valve 11 provided on the third pipeline 9. The second valve body 8 is specifically a one-way valve. The second pressure relief valve 11 is used to open when the air pressure in the preparation bottle 1 exceeds a first preset threshold, so as to discharge the gas in the preparation bottle 1 into the clean water tank 2. By setting the second pressure relief valve 11, the safety of the preparation bottle 1 can be further ensured, and potential safety hazards caused by excessive air pressure in the preparation bottle 1 can be avoided.

[0051] Specifically, the second pressure relief valve 11 can be configured to open when the air pressure in the preparation bottle 1 exceeds 0.6 MPa, that is, the first preset threshold can be 0.6 MPa, so as to achieve the purpose of pressure relief under high pressure. At this time, the second valve body 8 being a one-way valve can prevent the gas in the clean water tank 2 from flowing from the second pressure relief valve 11 into the preparation bottle 1.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the bubble water preparation device of the second embodiment further includes a third pressure relief valve 12. The third pressure relief valve 12 is respectively connected to the air outlet 504 of the bottle body 501, the air inlet of the preparation bottle 1, and the clean water tank 2, and is used to open when the air pressure in the bottle body 501 and / or the preparation bottle 1 exceeds a third preset threshold, so as to discharge the gas in the bottle body 501 and / or the preparation bottle 1 into the clean water tank 2. By setting the third pressure relief valve 12, the safety of the bottle body 501 and the preparation bottle 1 can be further ensured, and potential safety hazards caused by excessive air pressure in the bottle body 501 and / or the preparation bottle 1 can be avoided.

[0053] Specifically, the above-mentioned third preset threshold can be greater than the first preset threshold and the second preset threshold, so as to further improve the product safety through the third pressure relief valve 12 when the first pressure relief valve 10 and the second pressure relief valve 11 fail.

[0054] Specifically, the third pressure relief valve 12 can be configured to open when the air pressure in the preparation bottle 1 and / or the bottle body 501 exceeds 0.8 MPa, that is, the third preset threshold can be 0.8 MPa.

[0055] In some embodiments, such as Figure 3 and Figure 4As shown in the figure, the bubble water preparation device of the second embodiment further includes a third valve body 13 and a water outlet nozzle 14. The third valve body 13 is respectively connected to the water outlet nozzle 14 and the preparation bottle 1, and the third valve body 13 is electrically connected to the control device. The control device is further configured to send a third control instruction to open the third valve body 13 after the water in the water purification tank 2 and the gas in the bottle body 501 are mixed in the preparation bottle 1, so that under the action of the pressure in the preparation bottle 1, the bubble water in the preparation bottle 1 flows to the water outlet nozzle 14. In this way, the bubble water can directly flow to the water outlet nozzle 14 under the pressure in the preparation bottle 1, without the user manually pouring out the bubble water in the preparation bottle 1, and has the function of automatically discharging the bubble water.

[0056] Specifically, the above-mentioned third valve body 13 is configured as an electromagnetic valve, and by controlling the opening of the third valve body 13 by the control device, the discharge of the bubble water in the preparation bottle 1 can be controlled.

[0057] Specifically, the water outlet pipe connected to the third valve body 13 can be inserted into the bottom of the preparation bottle 1 to facilitate the rapid discharge of the bubble water in the preparation bottle 1.

[0058] In some embodiments, as Figures 1 to 4 shown, the bubble water preparation device may further include a ninth valve body 24. The liquid inlet of the ninth valve body 24 is connected to the pipeline where the eighth valve body 23 and the second pump body 22 are connected, and the liquid outlet of the ninth valve body 24 communicates with the water inlet of the water outlet nozzle 14. The ninth valve body 24 can be electrically connected to the control device. By controlling the ninth valve body 24 to open, the cold water prepared by the cooler 21 can be directly discharged from the ninth valve body 24 and the water outlet nozzle 14.

[0059] In some embodiments, as Figures 1 to 4 shown, the bubble water preparation device further includes a fourth valve body 15. The fourth valve body 15 is provided on the first pipeline 4 or the second pipeline 7. When the fourth valve body 15 is provided on the first pipeline 4, the fourth valve body 15 is provided upstream of the first valve body 6, and the fourth valve body 15 makes the water in the pipeline flow unidirectionally to the downstream of the fourth valve body 15. The above structure has a reasonable layout and is conducive to defining the water flow direction.

[0060] Specifically, the above-mentioned fourth valve body 15 can be specifically a check valve.

[0061] In some embodiments, as Figure 1 and Figure 2As shown, the bubble water preparation device of the first embodiment further includes a fifth valve body 16. Both the fourth valve body 15 and the fifth valve body 16 are provided on the first pipeline 4. The fifth valve body 16 is located downstream of the fourth valve body 15 and upstream of the first valve body 6. The control device is further configured to send a fourth control instruction to open the first valve body 6 after sending the second control instruction, so that the water in the hydraulic cavity 503 flows through the fifth valve body 16 and the first valve body 6 into the water purification tank 2. In this way, the water in the hydraulic cavity 503 can be discharged into the water purification tank 2 by controlling the opening of the first valve body 6, so that the switch assembly 502 is switched from the open state to the closed state, realizing precise control of the air outlet volume of the bottle body 501.

[0062] Specifically, the connection point of the second pipeline 7 and the first pipeline 4 is located upstream of the fifth valve body 16. When the first valve body 6 is opened to supply water to the water purification tank 2, the water pumped by the first pump body 3 can sequentially enter the water purification tank 2 through the fourth valve body 15, the fifth valve body 16, and the first valve body 6; when the first valve body 6 is closed to supply gas to the preparation bottle 1, the water pumped by the first pump body 3 can flow through the fourth valve body 15 into the hydraulic cavity 503; when the first valve body 6 is opened to discharge the water in the hydraulic cavity 503, the water in the hydraulic cavity 503 will be discharged into the water purification tank 2 through the fifth valve body 16 and the first valve body 6 in sequence.

[0063] Specifically, the connection point of the third pipeline 9 and the first pipeline 4 is located downstream of the fifth valve body 16.

[0064] In some embodiments, as Figure 3 and Figure 4 shown, the bubble water preparation device of the second embodiment further includes a sixth valve body 17. The sixth valve body 17 is respectively connected to the second pipeline 7 and the third pipeline 9. The control device is further configured to send a fourth control instruction to close the first pump body 3 after sending the second control instruction, so that the water in the hydraulic cavity 503 flows through the sixth valve body 17 and the second pressure relief valve 11 into the water purification tank 2. In this way, the water in the hydraulic cavity 503 can be discharged into the water purification tank 2 by controlling the closing of the first pump body 3, so that the switch assembly 502 is switched from the open state to the closed state, realizing precise control of the air outlet volume of the bottle body 501.

[0065] When the first valve body 6 of the above-mentioned bubble water preparation device of the second embodiment is opened to supply water to the water purification tank 2, the water pumped by the first pump body 3 can enter the water purification tank 2 through the first valve body 6; when the first valve body 6 is closed to supply gas to the preparation bottle 1, the water pumped by the first pump body 3 can flow through the fourth valve body 15 into the hydraulic cavity 503; when the first pump body 3 is closed to discharge the water in the hydraulic cavity 503, the water in the hydraulic cavity 503 will be discharged into the water purification tank 2 through the sixth valve body 17 and the second pressure relief valve 11 in sequence.

[0066] Specifically, as Figure 3 and Figure 4 shown, the connection point between the liquid inlet of the sixth valve body 17 and the second pipeline 7 is located downstream of the fourth valve body 15, and the connection point between the liquid outlet of the sixth valve body 17 and the third pipeline 9 is located downstream of the second valve body 8.

[0067] The working process of the bubble water preparation device in the first embodiment is specifically described below: First, the first pump body 3 and the seventh valve body 18 are opened through the control device. After the water pumped by the first pump body 3 is filtered by the filter 19, the concentrated water filtered out is discharged through the concentrated water drain valve 20, and the clear water filtered out flows through the fourth valve body 15, the fifth valve body 16, and the first valve body 6 to the clean water tank 2. The water in the clean water tank 2 flows to the cooler 21 to prepare cold water cooled by the cooler 21. The cold water is pumped into the preparation bottle 1 under the action of the second pump body 22. When the water level sensor in the preparation bottle 1 detects that the preset water level is reached, the control device controls the second pump body 22 to stop working. At the same time, the control device controls the seventh valve body 18 and the first pump body 3 to be opened, and the first valve body 6 to be closed, so that the water pumped by the first pump body 3 can flow through the fourth valve body 15 into the hydraulic cavity 503. After the gas supply in the bottle body 501 reaches the requirement, when the first valve body 6 is controlled to be opened by the control device to discharge the water in the hydraulic cavity 503, the water in the hydraulic cavity 503 will be discharged into the clean water tank 2 through the fifth valve body 16 and the first valve body 6 in sequence to stop supplying gas to the preparation bottle 1. Then, the user can manually pour out the prepared bubble water in the preparation bottle 1.

[0068] Furthermore, as Figure 2 shown, when the air pressure in the preparation bottle 1 exceeds the first preset threshold, the gas in the preparation bottle 1 can be discharged into the clean water tank 2 through the second valve body 8 and the first valve body 6 in sequence. In addition, by setting the first pressure relief valve 10, the gas in the preparation bottle 1 can be discharged into the clean water tank 2 through the first pressure relief valve 10 when the air pressure in the preparation bottle 1 exceeds the second preset threshold, so as to achieve the purpose of improving product safety.

[0069] The working process of the bubble water preparation device in Embodiment 2 is specifically described as follows: First, the control device opens the first pump body 3 and the seventh valve body 18. After the water pumped by the first pump body 3 is filtered by the filter 19, the concentrated water filtered out is discharged through the concentrated water drain valve 20, and the clear water filtered out flows through the fourth valve body 15, the fifth valve body 16, and the first valve body 6 to the clean water tank 2. The water in the clean water tank 2 flows to the cooler 21 to prepare cold water cooled by the cooler 21. The cold water is pumped into the preparation bottle 1 by the second pump body 22. When the water level sensor in the preparation bottle 1 detects that the preset water level is reached, the control device controls the second pump body 22 to stop working. At the same time, the control device controls the seventh valve body 18 and the first pump body 3 to open, and the first valve body 6 to close, so that the water pumped by the first pump body 3 can flow through the fourth valve body 15 into the hydraulic chamber 503. After the gas supply volume in the bottle body 501 meets the requirements, when the control device controls the first pump body 3 to close to drain the water in the hydraulic chamber 503, the water in the hydraulic chamber 503 will sequentially flow through the sixth valve body 17 and the second pressure relief valve 11 and be drained into the clean water tank 2 to stop supplying gas to the preparation bottle 1. Then, the user can control the third valve body 13 to open through the control device, so that the bubble water flows directly to the water outlet 14 under the action of the pressure in the preparation bottle 1, without the user manually pouring out the bubble water in the preparation bottle 1, and has the function of automatically discharging the bubble water.

[0070] Further, as Figure 2 shown, when the air pressure in the preparation bottle 1 exceeds the first preset threshold, the gas in the preparation bottle 1 can sequentially flow through the second valve body 8 and the second pressure relief valve 11 and be discharged into the clean water tank 2. In addition, by setting the third pressure relief valve 12, when the air pressure in the preparation bottle 1 and / or the bottle body 501 exceeds the third preset threshold, the gas in the preparation bottle 1 and / or the bottle body 501 can be discharged into the clean water tank 2 through the third pressure relief valve 12 to achieve the purpose of improving product safety.

Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
