Description

Technical Field

[0001] This application relates to the field of home appliances, and in particular to a sparkling water machine. Background Technology

[0002] As people's living standards continue to improve, sparkling water has become a common beverage in daily life. Sparkling water is made by mixing carbon dioxide and water, and its slightly acidic nature can help stimulate the stomach.

[0003] Because the process of making sparkling water requires infusing gas into a liquid, the resulting sparkling water will generate enormous pressure due to the incorporation of a large amount of gas. If the sparkling water is directly expelled, it will spray out. The sprayed sparkling water will not only reduce the solubility of the gas, causing the gas that has already been incorporated into the liquid to escape, affecting the taste of the sparkling water, but it will also spray onto the user, affecting the user's experience.

[0004] In existing technologies, such as utility model patent CN210687132U, a pressure relief valve is installed on the mixing chamber to reduce the pressure of the bubble water, thereby preventing the bubble water from spraying out. Another example is utility model CN214284525U, where a pressure relief device is manually pressed at the outlet to release the pressure of the discharged bubble water before it is discharged.

[0005] The above technical solutions cannot accurately and automatically depressurize the bubbly water reaching the outlet, thus failing to meet the user's needs. Summary of the Invention

The first water inlet is connected to the first chamber, and the water outlet is connected to the second chamber.

[0010] A second water inlet is provided on the pressure reducing device to connect the first chamber and the second chamber;

[0011] Liquid flows into each chamber through each water inlet hole, and the pressure difference between the chambers causes the pressure reducing device to slide along the inner wall of the chamber.

[0012] The following also provides several optional modes, but not as an additional limitation of the above general scheme, just a further supplement or preferred, without technical or logical contradiction, each optional mode can be combined with the above general scheme, but also can be combined between multiple optional modes.

[0013] Optionally, during the sliding process, the pressure reducing device is spaced apart from the water outlet hole, or at least a portion of the pressure reducing device overlaps the water outlet hole.

When a component is referred to as being "disposed on" another component, it can be directly disposed on the other component or there can be a middle component.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used in this description, the terms "and / or" includes any and all combinations of one or more of the associated listed items.

[0045] Reference Figure 1 and Figure 6 As shown, in the prior art, a mixing cavity for mixing gas and liquid is arranged on the bubble water machine 100, and the bubble water in the mixing cavity is directly discharged out of the bubble water machine 100. Because there is a large pressure in the mixing cavity, the bubble water discharged out of the bubble water machine 100 may sometimes be ejected due to the excessive pressure, and the solubility of the gas in the liquid is reduced during the ejection process, causing part of the gas to escape from the bubble water, which affects the taste of the bubble water. Therefore, in the present application, a water outlet nozzle 200 is arranged on the bubble water machine 100, and a control valve 300 is arranged between the mixing cavity and the water outlet nozzle 200, and the bubble water is discharged from the water outlet nozzle 200 at a constant pressure after passing through the control valve 300. The flow rate of the bubble water is reduced by the control valve 300, so that the kinetic energy of the bubble water is reduced while ensuring that the bubble water can be smoothly discharged from the water outlet nozzle 200, thereby preventing the ejection phenomenon from occurring.

[0046] A control valve 300, comprising a valve body 301, a first water inlet hole 302 and a water outlet hole 304 are arranged on the valve body 301, the control valve 300 further comprises:

[0047] A chamber 400 is used to reduce the pressure of the liquid flowing into the first water inlet hole 302;

[0048] A pressure reducing device 500 is attached to the inner wall of the control valve 300, and divides the chamber 400 into a first chamber 401 and a second chamber 402 along the axial direction of the control valve 300, the first water inlet hole 302 is in communication with the first chamber 401, and the water outlet hole 304 is in communication with the second chamber 402;

[0049] A second water inlet hole 303 is arranged on the pressure reducing device 500, and is used to communicate the first chamber 401 and the second chamber 402;

[0050] The liquid flows into the chambers 400 through the water inlet holes, and the pressure difference between the chambers 400 causes the pressure reducing device 500 to slide along the inner wall of the chamber 400.

[0051] In this embodiment, the liquid in the mixing chamber enters the control valve 300 through the first water inlet hole 302, and because the pressure in the mixing chamber is relatively high, the liquid has a relatively high kinetic energy when it enters the control valve 300 through the first water inlet hole 302. At this time, the liquid entering the first chamber 401 gives the pressure reducing device 500 a first pressure in the positive direction of the y-axis, and the pressure reducing device 500 slides in the positive direction of the y-axis. At this time, the pressure reducing device 500 gradually approaches the water outlet hole 304. At the same time, the liquid in the first chamber 401 enters the second chamber 402 through the second water inlet hole 303, and the liquid in the second chamber 402 gives the pressure reducing device 500 a second pressure in the negative direction of the y-axis. As the liquid in the second chamber 402 gradually increases, the second pressure also gradually increases. When the sum of the second pressure and the gravitational potential energy of the pressure reducing device 500 is equal to the first pressure, the pressure reducing device 500 stops rising. When the liquid in the second chamber 402 rises to a certain height, the sum of the second pressure and the gravitational potential energy of the pressure reducing device 500 is greater than the first pressure, and the pressure reducing device 500 moves in the negative direction of the y-axis. At this time, the pressure reducing device 500 gradually moves away from the water outlet hole 304, and the liquid in the second chamber 402 is discharged out of the bubble water machine 100 through the water outlet hole 304. The arrangement of the second water inlet hole 303 prolongs the path of the liquid entering the second chamber 402, further reducing the kinetic energy of the liquid. The bubble water originally has a strong pressure and kinetic energy, but due to the first chamber 401 and the second chamber 402 in the chamber 400, the pressure and kinetic energy of the bubble water are reduced, thereby reducing the pressure and kinetic energy of the bubble water discharged out of the bubble water machine 100, preventing the bubble water from spouting when it is discharged out of the body, and preventing the solubility of the bubble water from being reduced.

[0052] ReferenceFigure 2 As shown, the pressure reducing device 500 is arranged to block the liquid from flowing out of the water outlet hole 304 directly to the outside of the bubble water machine 100. The pressure reducing device 500 can reduce the pressure of the liquid. When the liquid reaches the required pressure, the liquid can flow out of the water outlet hole 304 to the outside of the bubble water machine 100. During the sliding process, the pressure reducing device 500 is spaced apart from the water outlet hole 304 or at least a part of the pressure reducing device 500 overlaps the water outlet hole 304. In one embodiment, the pressure reducing device 500 is spaced apart from the water outlet hole 304 by a certain distance. When the liquid enters the first chamber 401, the pressure reducing device 500 starts to move in the positive direction of the y-axis. At this time, the water outlet hole 304 is in an open state. The liquid in the first chamber 401 enters the second chamber 402 through the second water inlet hole 303. The liquid level in the second chamber 402 gradually rises and eventually flows out of the water outlet hole 304. At this time, the pressure of the liquid flowing out of the water outlet hole 304 is the required liquid pressure. During the whole process, the water outlet hole 304 is always in an open state and is not blocked by the pressure reducing device 500, which can simplify the pressure reducing device 500. In one embodiment, in order to better reduce the pressure of the liquid in the second chamber 402, at least a part of the pressure reducing device 500 overlaps the water outlet hole 304. When the liquid enters the first chamber 401, the pressure reducing device 500 starts to move in the positive direction of the y-axis. At this time, the water outlet hole 304 is in an open state. The liquid in the first chamber 401 enters the second chamber 402 through the second water inlet hole 303. The liquid level in the second chamber 402 gradually rises. At this time, the kinetic energy and pressure of the liquid entering the first chamber 401 also gradually rise. When the pressure reducing device 500 partially or completely overlaps the water outlet hole 304, the water outlet hole 304 is in a semi-blocked or blocked state. The sum of the second pressure and the gravitational potential energy of the pressure reducing device 500 is equal to the first pressure. The liquid level of the second chamber 402 is higher than the lowest position of the water outlet hole 304. With the increase of the second pressure, the pressure reducing device 500 moves in the negative direction of the y-axis. The water outlet hole 304 gradually opens. The bubble water is discharged from the water outlet hole 304 out of the chamber 400, thereby realizing the pressure reduction of the bubble water.

[0053] Reference Figure 7As shown, in order to ensure that the pressure relief device 500 can slide on the valve body 301, the pressure relief device 500 is in a disc or cylindrical structure. In order to make the pressure relief device 500 slide on the valve body 301 as much as possible, the disc or cylindrical structure can make the pressure relief device 500 slide on the valve body 301, reduce the friction coefficient, and thus ignore the influence of the friction force of the pressure relief device 500 in the sliding process as much as possible. In order to achieve this effect, one of the pressure relief device 500 or the valve body 301 can also be designed as a roller, and the friction force can be reduced by rolling movement between the two.

[0054] In one embodiment, when the pressure relief device 500 is in a disc shape, the water outlet hole 304 can be blocked or opened by the height of the disc itself. The disc design can minimize the friction between the pressure relief device 500 and the valve body 301, and more accurately reduce the pressure of the bubble water. In addition, the disc has a foolproof structure, and is more convenient to assemble.

[0055] Reference Figure 7 As shown, in one embodiment, when the pressure relief device 500 is in a cylindrical structure, the cylindrical structure includes a support part 501 and a sliding part 502 designed in a ring around the support part 501. The second water inlet hole 303 is opened on the support part 501, and the sliding part 502 is in close contact with the valve body 301. The sliding part 502 slides on the valve body 301 to block and open the water outlet hole 304. Since the bubble water has a large pressure and kinetic energy when entering the first chamber 401 from the first water inlet hole 302, the impact force on the pressure relief device 500 is large. In order to prevent the pressure relief device 500 from being tilted or inclined after being subjected to a large impact force, the pressure relief device 500 is designed in a cylindrical structure, the extension direction of the sliding part 502 is the same as the extension direction of the valve body 301, and the sliding part 502 is limited by the valve body 301. Thus, the shaking of the cylindrical structure in the valve body 301 is limited.

[0056] In one embodiment, when the pressure relief device 500 does not block the water outlet hole 304 during the sliding process, the height of the bubble water in the second chamber 402 is higher than the height of the pressure relief device 500, and the bubble water can overflow from the second chamber 402 to the outside of the bubble water machine 100. In order to prevent the bubble water in the second chamber 402 from flowing back to the first chamber 401 or other components of the control valve 300, the pressure relief device 500 is sealingly connected with the valve body 301, so that when the height of the bubble water in the second chamber 402 is higher than the height of the pressure relief device 500, the bubble water cannot overflow through the gap between the pressure relief device 500 and the valve body 301, ensuring the pressure relief effect of the control valve 300, preventing the overflow of the bubble water from damaging other components of the control valve 300, and prolonging the service life of the control valve 300.

[0057] Referring to Figure 2 As shown, when the pressure of the bubble water entering the first chamber 401 is too high, the excessive impact force can move the pressure relief device 500 along the axial direction of the valve body 301 to an excessive stroke, thereby pushing out the valve body 301. Therefore, the valve cover 305 is arranged on the valve body 301 to limit the displacement of the pressure relief device 500. At the same time, the arrangement of the valve cover 305 can prevent foreign matter from falling into the chamber 400, ensuring the safety and hygiene of the chamber 400.

[0058] Referring to Figure 3 As shown, the control valve 300 provided with the valve cover 305 can cause the pressure relief device 500 to tightly adhere to the valve cover 305 due to a strong impact force, and cannot slide along the axial direction of the valve body 301, resulting in the water outlet hole 304 being always blocked, and the bubble water in the second chamber 402 cannot be discharged through the water outlet hole 304. Therefore, the pressure relief hole 314 is arranged on the pressure relief device 500, and when the pressure relief device 500 cannot slide due to the adhesion of the valve cover 305, part or all of the pressure relief hole 314 is connected with the water outlet hole 304, and the liquid in the chamber 400 is discharged through the pressure relief hole 314, thereby ensuring the normal operation of the bubble water machine 100.

[0059] As a preferred solution, in order to make the pressure relief hole 314 at least partially coincide with the water outlet hole 304, the angle of the pressure relief hole 314 is greater than 360° / N, and N is the number of the water outlet hole 304.

[0060] When the pressure of the bubble water is too high or needs to be reduced, the flow regulating device 600 is arranged in the second chamber 402 to change the water outlet speed of the water outlet hole 304. By arranging the flow regulating device 600, the pressure of the bubble water can be greatly reduced. When the pressure of the bubble water is regulated only by the pressure reducing device 500, due to the limited weight of the pressure reducing device 500, when different bubble water pressures need to flow out of the bubble water machine 100, only by adjusting the axial length of the valve body 301 to adjust the bubble water pressure, the overall volume of the control valve 300 will increase, affecting the overall layout of the bubble water machine 100. By arranging the flow regulating device 600, the pressure of the bubble water can be adjusted without changing the size of the original control valve 300, so as to change the water outlet speed of the water outlet hole 304, and the setting of the water outlet nozzle 200 can be adapted to different requirements.

[0061] Referring to Figure 8 and Figure 9 In order to reduce the volume of the control valve 300 and facilitate the installation of the control valve 300, at least a part of the flow regulating device 600 is arranged inside the second chamber 402. When the pressure of the bubble water regulated by the flow regulating device 600 is fixed, the flow regulating device 600 can be arranged entirely in the second chamber 402; when the flow regulating device 600 is arranged to be able to regulate the pressure of the bubble water, a part of the flow regulating device 600 extends into the second chamber 402, and the other part extends out of the control valve 300 through the valve cover 305 and is in sliding connection with the valve cover 305, so that the flow regulating device 600 can be adjusted by sliding to control the pressure of the bubble water flowing out of the second chamber 402.

[0062] Referring to Figure 8 and Figure 9As shown, the setting of the flow regulating device 600 can be divided into several cases, the flow regulating device 600 is an elastic device 601 or a blocking device 602. When the flow regulating device 600 is an elastic device 601, the elastic device 601 can be entirely arranged in the second control cavity, in one embodiment, one end of the elastic device 601 abuts against the pressure reducing device 500, and the other end abuts against the valve cover 305, when the bubble water enters the first chamber 401, the pressure reducing device 500 moves along the positive direction of the y-axis, at this time, the elastic device 601 generates an elastic force along the negative direction of the y-axis on the pressure reducing device 500, so as to prevent the movement of the pressure reducing device 500; when one end of the elastic device 601 abuts against the pressure reducing device 500, and the other end is spaced apart from the valve body 301 by a certain distance, or one end of the elastic device 601 abuts against the valve body 301, and the other end is spaced apart from the pressure reducing device 500 by a certain distance, when the pressure reducing device 500 moves along the axial direction by a certain distance, and the two ends of the elastic device 601 abut against the pressure reducing device 500 and the valve cover 305 respectively, the elastic device 601 generates an elastic force along the negative direction of the y-axis on the pressure reducing device 500, so as to prevent the movement of the pressure reducing device 500. Different setting positions of the same elastic device 601 can change the elastic potential energy of the elastic device 601, so as to adjust the pressure of the bubble water flowing out of the second chamber 402, and meet the needs of the user. At the same time, different elastic potential energies of the elastic device 601 can also be selected to adjust the pressure of the bubble water flowing out of the second chamber 402.

[0063] In one embodiment, the flow of the bubble water flowing out of the water outlet hole 304 is controlled by controlling the flow of the bubble water entering the second chamber 402, therefore, the flow regulating device 606 is arranged as a blocking device 602. The blocking device 602 is provided with a blocking piece 603, which controls the water inflow of the second water inlet hole 303. The blocking device 602 is provided with the blocking piece 603 near one end close to the second water inlet hole 303, and the blocking piece 603 cooperates with the second water inlet hole 303 to reduce the flow rate of the bubble water entering the second chamber 402. The blocking piece 603 can be arranged in the same shape as the second water inlet hole 303, or other shapes that can cooperate with the second water inlet hole 303, such as a cube, a triangular body, etc. As a preferred scheme, the blocking piece 603 is arranged as a triangular body, so that in the process of blocking, the area of the bubble water of the second water inlet hole 303 in contact with the blocking piece 603 is small at the beginning, and the pressure of the bubble water on the blocking piece 603 is also small, which can prevent the blocking piece 603 from moving along the positive direction of the y-axis due to excessive pressure of the bubble water, and as the blocking device 602 gradually approaches the second water inlet hole 303, the area of the second water inlet hole 303 covered by the blocking piece 603 also becomes larger and larger, and the flow rate of the bubble water flowing out of the second water inlet hole 303 also gradually slows down, which is beneficial to the adjustment of the flow of the bubble water.

[0064] Reference Figure 9As shown, in order to prevent the blocking device 602 from completely blocking the second water outlet hole 304, thereby causing the bubble water in the first chamber 401 to be unable to enter the second chamber 402, the overflow part 604 is arranged on the blocking part 603, and when the blocking device 602 cooperates with the second water inlet hole 303, the liquid enters the second chamber 402 from the first chamber 401 through the overflow part 604. The arrangement of the overflow part 604 makes the blocking device 602 unable to completely block the second water inlet hole 303, and when the blocking device 602 is in close contact with the second water inlet hole 303, there is still a gap to enable the bubble water to enter the second chamber 402 from the first chamber 401, thereby ensuring that the control valve 300 can normally deliver the bubble water.

[0065] The overflow part 604 is a protrusion that partially or completely surrounds the blocking part 603, and when the blocking device 602 blocks the second water outlet hole 304, a gap is left between the protrusion and the valve body 301, and the bubble water flows into the second chamber 402 from the gap. The greater the proportion of the overflow part 604 occupying the blocking part 603, the greater the flow of the bubble water into the second chamber 402.

[0066] The arrangement positions of the blocking device 602 and the elastic device 601 are not limited, and they can be arranged on the valve cover 305 or on the valve body 301, as long as they can cooperate with the second water outlet hole 304 during use to prevent the bubble water from entering the second chamber 402 from the second water outlet hole 304.

[0067] Reference Figure 9 As shown, in the embodiment, the blocking device 602 is arranged on the valve cover 305 for the convenience of maintenance of the blocking device 602 and blocking of the second water outlet hole 304. In order to prevent the pressure reduction device 500 from tilting or overturning due to the kinetic energy of the bubble water, the second water outlet hole 304 is arranged at the central position of the pressure reduction device 500, which can enable the pressure reduction device 500 to be balanced when the bubble water enters the second chamber 402 from the first chamber 401, so that the pressure reduction device 500 always remains balanced. In order to better cooperate with the second water outlet hole 304 arranged at the central position of the pressure reduction device 500, as a preferred scheme, the blocking device 602 is arranged at the central position of the valve cover 305 and corresponds to the second water outlet hole 304, which can timely block the second water outlet hole 304 and has a simple structure and is convenient to install. Moreover, the valve cover 305 and the valve body 301 are detachably connected, and the blocking device 602 arranged on the valve cover 305 can be more convenient to maintain and replace when the blocking device 602 has a problem.

[0068] In order to adjust the pressure of the bubble water flowing out of the outlet hole 304, the blocking device 602 is arranged to move relative to the valve cover 305. The blocking device 602 is arranged to pass through the valve cover 305, with one part exposed outside the valve cover 305 and the other part extending into the control valve 300, and is fixed by the valve cover 305. A sliding device is arranged between the valve cover 305 and the blocking device 602, so that the blocking device 602 can move along the axial direction of the control valve 300. By changing the length of the blocking device 602 in the control valve 300, the pressure of the bubble water flowing out of the outlet hole 304 is changed. As a preferred solution, the blocking device 602 is arranged in a cylindrical structure, with a blocking member 603 arranged at one end of the blocking device 602 for blocking the second inlet hole 303, and a holding portion 605 arranged at the other end of the blocking device 602, so that a user can control the holding portion 605 to slide the blocking device 602 along the axial direction. A sliding portion is arranged between the blocking member 603 and the holding portion 605, which cooperates with the valve body 301 to allow the blocking device 602 to slide along the axial direction of the control valve 300.

[0069] Referring to Figure 2 and Figure 3 In order to adjust the pressure of the bubble water flowing out of the outlet hole 304, the blocking device 602 is arranged to move relative to the valve cover 305. The blocking device 602 is arranged to pass through the valve cover 305, with one part exposed outside the valve cover 305 and the other part extending into the control valve 300, and is fixed by the valve cover 305. A sliding device is arranged between the valve cover 305 and the blocking device 602, so that the blocking device 602 can move along the axial direction of the control valve 300. By changing the length of the blocking device 602 in the control valve 300, the pressure of the bubble water flowing out of the outlet hole 304 is changed. As a preferred solution, the blocking device 602 is arranged in a cylindrical structure, with a blocking member 603 arranged at one end of the blocking device 602 for blocking the second inlet hole 303, and a holding portion 605 arranged at the other end of the blocking device 602, so that a user can control the holding portion 605 to slide the blocking device 602 along the axial direction. A sliding portion is arranged between the blocking member 603 and the holding portion 605, which cooperates with the valve body 301 to allow the blocking device 602 to slide along the axial direction of the control valve 300.

[0070] In order to adjust the pressure of the bubble water flowing out of the outlet hole 304, the blocking device 602 is arranged to move relative to the valve cover 305. The blocking device 602 is arranged to pass through the valve cover 305, with one part exposed outside the valve cover 305 and the other part extending into the control valve 300, and is fixed by the valve cover 305. A sliding device is arranged between the valve cover 305 and the blocking device 602, so that the blocking device 602 can move along the axial direction of the control valve 300. By changing the length of the blocking device 602 in the control valve 300, the pressure of the bubble water flowing out of the outlet hole 304 is changed. As a preferred solution, the blocking device 602 is arranged in a cylindrical structure, with a blocking member 603 arranged at one end of the blocking device 602 for blocking the second inlet hole 303, and a holding portion 605 arranged at the other end of the blocking device 602, so that a user can control the holding portion 605 to slide the blocking device 602 along the axial direction. A sliding portion is arranged between the blocking member 603 and the holding portion 605, which cooperates with the valve body 301 to allow the blocking device 602 to slide along the axial direction of the control valve 300.

[0071] Referring to Figure 2As shown, the adjusting device 606 is provided in a rod-shaped structure, a locking piece 607 is arranged at one end of the rod-shaped structure, the locking piece 607 is combined by a plurality of mutually symmetrical prismatic protrusions 609, and the locking piece 607 is fixed and limited by cooperating with the limiting groove 307 on the fastening part 306. A blocking piece 608 is arranged at the other end of the rod-shaped structure, and the compression or elongation of the elastic device 601 is realized by the abutment between the blocking piece 608 and the elastic device 601. The blocking piece 608 is a ring-shaped protrusion arranged on the adjusting device 606, which is arranged around the circumference of the adjusting device 606 or partially arranged around the circumference of the adjusting device 606. As a preferred scheme, since the blocking piece 608 needs to bear the elastic force of the elastic device 601, in order to prevent the elastic force from being too large and causing damage to the blocking piece 608, and in order to enable the blocking piece 608 to better drive the elastic device 601 to move along the axial direction of the control valve 300, the protrusion is arranged around the entire circumference of the adjusting device 606.

[0072] Reference Figure 2 and Figure 3 As shown, when the bubble water enters the control valve 300 from the first water inlet hole 302, the kinetic energy of the bubble water will drive the pressure reducing device 500 to move along the positive direction of the y-axis. If the kinetic energy of the bubble water is large, a large impact force will be generated, causing the valve cover 305 to be separated from the control valve 300. In order to strengthen the fixation of the valve cover 305, a pressurizing plate 308 is arranged on the valve cover 305 to strengthen the fixation of the valve cover 305. The pressurizing plate 308 is provided with an avoiding hole 309 for the adjusting device 606 and the fastening part 306 to pass through, and the pressurizing plate 308 is fixedly connected with the valve cover 305. When the impact force of the bubble water acts on the valve cover 305, the pressurizing plate 308 limits the valve cover 305 through its own gravity and the connection strength between the pressurizing plate 308 and the valve cover 305, preventing displacement of the valve cover 305.

[0073] In order to strengthen the connection strength between the pressurizing plate 308 and the valve cover 305, a plurality of through holes 310 are arranged on the pressurizing plate 308, and the pressurizing plate 308 and the valve cover 305 are connected by passing through the through holes 310. The bolt connection can make the pressurizing plate 308 and the valve cover 305 detachable, facilitating cleaning and maintenance of the inside of the control valve 300. As a preferred scheme, the number of through holes 310 is 3, and the through holes 310 are symmetrically arranged. Alternatively, the pressurizing plate 308 and the valve cover 305 are fixedly connected by welding to strengthen the connection strength between them.

[0074] Reference Figure 6As shown, in order to prevent the effusion of the sparkling water between the adjusting device 606 and the control valve 300, a sealing device 700 is arranged between the adjusting device 606 and the valve cover 305. The effusion of the sparkling water from the adjusting device 606 not only causes the waste of the sparkling water, but also the sparkling water remaining in the adjusting device 606 and the effusion of the sparkling water outside the control valve 300 can cause damage to the arrangement and easily breed bacteria, which can cause food safety problems in the long run, so the sparkling water needs to be controlled in the first and second chambers 402. As a preferred solution, the sealing device 700 is a first sealing ring 701 arranged circumferentially around the adjusting device 606, and the first sealing ring 701 is arranged at one end close to the locking member 607, and the first sealing ring 701 will be displaced with the movement of the adjusting device 606.

[0075] Referring to Figure 5 and Figure 6 As shown, when the sparkling water in the control valve 300 is delivered outside the sparkling water machine 100, in order to enable the user to automatically control the amount of sparkling water delivered each time, the control valve 300 is provided with a switch assembly 800, one end of which is connected with the water outlet hole 304 and the other end is connected with the water outlet nozzle 200, and the switch assembly 800 is used to control the flow of the liquid from the chamber 400 to the water outlet nozzle 200. The switch assembly 800 can control the on-off of the path of the sparkling water flowing into the water outlet nozzle 200, so as to control the flow of the sparkling water. When the sparkling water is lowered to the required pressure and flows out from the water outlet hole 304, it first enters the water outlet channel 801, and when the switch assembly 800 opens the water outlet channel 801, the sparkling water flows out from the water outlet channel 801 and enters the water outlet nozzle 200; when the switch assembly 800 closes the water outlet channel 801, the sparkling water stays in the water outlet channel 801, and the sparkling water machine 100 stops water delivery.

[0076] Referring to Figure 5 As shown, in order to facilitate the entry of the sparkling water from the water outlet channel 801 into the water outlet nozzle 200, the highest position of the water outlet nozzle 200 is equal to or lower than the position of the water outlet channel 801. The water outlet channel 801 can be arranged horizontally or obliquely from the water outlet hole 304 to the water outlet nozzle 200. By limiting the position of the water outlet channel 801 and the water outlet nozzle 200, it can be ensured that the sparkling water can flow out of the sparkling water machine 100 by its own gravitational potential energy, and prevent the sparkling water with reduced pressure from being unable to normally discharge out of the sparkling water machine 100.

[0077] Referring to Figure 5 and Figure 6As shown, the switch assembly 800 controls the opening and closing of the path through the electromagnetic valve 802, and the control of the electromagnetic valve 802 can respond faster, thereby timely opening or closing the water outlet passage 801. The switch assembly 800 includes a first connecting rod 803, a second connecting rod 804, an electromagnetic valve 802, and a reset spring 805, and the electromagnetic valve 802 includes an electromagnetic valve body 806 and an electromagnetic valve core 807. The first connecting rod 803 is fixed at one end on the electromagnetic valve body 806 and at the other end on the electromagnetic valve core 807; one end of the second connecting rod is connected to the first connecting rod, and when one connecting rod moves, the other connecting rod also moves, and the other end of the second connecting rod is provided with a passage sealing device 808 for blocking the flow of bubble water in the water outlet nozzle 200 direction. In order to prevent the passage sealing device 808 from blocking the bubble water, the bubble water flows through the gap between the electromagnetic valve body 806 to other places. In order to enable the second connecting rod 804 to automatically return to the original position after displacement, the reset spring 805 connected to the second connecting rod 804 is arranged on the electromagnetic valve body 806.

[0078] When the electromagnetic valve 802 is powered on, the electromagnetic valve core 807 moves in the axial direction of the electromagnetic valve 802, thereby driving the first connecting rod 803 to move in the axial direction of the electromagnetic valve 802, and pressing the second connecting rod 804 to move in the opposite direction of the electromagnetic valve core 807, thereby driving the passage sealing device 808 to open the water outlet passage 801, and the bubble water enters the water outlet nozzle 200 through the water outlet passage 801 to discharge the bubble water machine 100 outside.

[0079] When the electromagnetic valve 802 is powered off, the second connecting rod is reset under the action of the reset spring 805, and pushes the first connecting rod 803 and the electromagnetic valve core 807 to reset, thereby driving the passage sealing device 808 to block the water outlet passage 801, and the bubble water is blocked by the passage sealing device 808 and cannot be discharged from the bubble water machine 100. When the pressure of the bubble water is greater, the sealing effect of the passage sealing device 808 is better.

[0080] Reference Figure 2As shown, when the valve body 301 is directly connected with the pressure reducing device 500, the pressure reducing device 500 is prone to be tilted when sliding on the valve body 301 due to the rough surface of the valve body 301. Therefore, the valve core 311 is arranged between the valve body 301 and the pressure reducing device 500, and the sealing device 700 is arranged between the valve body 301 and the valve core 311. The arrangement of the valve core 311 can prevent the pressure reducing device 500 from being tilted or falling during the sliding process. The valve core 311 comprises a body 312 and a fixing portion 313. The body 312 is in a cylindrical structure, and the upper and lower ends of the body 312 are in an open state. One end is used for sliding of the pressure reducing device 500, and the other end is used for the valve cover 305 and the adjusting device 606 to extend into the second chamber 402. The inner surface of the body 312 is a smooth curved surface, which cooperates with the shape of the pressure reducing device 500 to reduce the friction between the pressure reducing device 500 and the valve core 311. The fixing portion 313 is arranged on the side away from the pressure reducing device 500 and surrounds the outer periphery of the body 312, which is used to strengthen the connection strength between the valve core 311 and the valve body 301 and prevent the valve core 311 from being impacted by the power of the bubble water.

[0081] Reference Figure 2 As shown, the third sealing ring 703 is arranged between the valve core 311 and the valve body 301, surrounds the valve core 311, and is arranged between the body 312 and the fixing portion 313 to strengthen the fixation of the third sealing ring 703. The arrangement of the third sealing ring 703 can prevent the bubble water from entering the gap between the valve core 311 and the valve body 301, reduce the waste of the bubble water, and protect the equipment inside the control valve 300 from being damaged by the bubble water.

[0082] Reference Figure 5 As shown, in order to prevent external substances from entering the control valve 300, the fourth sealing ring 704 is arranged between the valve cover 305 and the valve body 301 to reduce the entry of external substances into the control valve 300, especially to prevent external substances from entering the chamber 400 and causing safety and health problems.

[0083] In order to prevent the bubble water in the switch assembly 800 from flowing back into the control valve 300, the second sealing ring 702 is arranged between the water outlet channel 801 and the electromagnetic valve body 806 to control the bubble water in the storage cavity between the water outlet channel 801 and the channel sealing ring. When the switch assembly 800 opens the water outlet channel 801, the bubble water can be discharged in time at the water outlet nozzle 200.

[0084] In order to reduce the pressure of the bubble water, the height of the water inlet hole is lower than the height of the water outlet hole 304. In this way, the kinetic energy of the bubble water is converted into gravitational potential energy during the passage of the bubble water through the control valve 300, which can effectively reduce the pressure of the bubble water and prevent the bubble water discharged from the water outlet nozzle 200 from being sprayed due to excessive pressure.

[0085] ReferenceFigure 2 、 Figure 7 、 Figure 8 and Figure 9 As shown in the figures, in order to prevent the pressure reducing device 500 from blocking the first water inlet hole 302 during sliding, so that the bubble water cannot pass through the first water inlet hole 302 into the first chamber 401, and at the same time when the pressure of the bubble water in the second chamber 402 reaches the required pressure, the communication between the first chamber 401 and the second chamber 402 is blocked, for this purpose, a limiting piece 900 is arranged in the first chamber 401, and at least a part of the first water inlet hole 302 is in communication with the first chamber 401 through the limiting piece 900. The arrangement of the limiting piece 900 can limit the sliding of the pressure reducing device 500, so that the pressure reducing device 500 is spaced apart from the bottom edge of the valve body 301 by a certain distance, while also ensuring that the bubble water can pass through the first water inlet hole 302 into the first chamber 401. Through the limitation of the limiting piece 900, when the pressure reducing device 500 is operated to the lowest position, at this time the height of the pressure reducing device 500 is higher than the lowest height of the first water inlet hole 302, so that the first water inlet hole 302 always maintains a state of communication with the first chamber 401.

[0086] In order to enhance the strength of the limiting piece 900, the limiting piece 900 is arranged on the valve body 301 or the pressure reducing device 500. The limiting piece 900 can be arranged on the valve body 301 and integrated with the valve body 301 or arranged separately from the valve body 301; the limiting piece 900 can also be arranged on the pressure reducing device 500 and slide with the pressure reducing device 500, and be integrated with the pressure reducing device 500 or arranged separately from the pressure reducing device 500. When the limiting piece 900 is arranged on the pressure reducing device 500, it cannot affect the bubble water from the first chamber 401 to pass through the second water inlet hole 303 into the second chamber 402, that is, the bubble water can pass through the limiting piece 900 into the second water inlet hole 303 and finally reach the second chamber 402.

[0087] In the embodiment, the limiting member 900 is in the shape of a boss, and is arranged on the valve body 301 in an integral or separate manner. In order to prevent the limiting member 900 from passing through the second water inlet hole 303, so as to fail to achieve the functions of limiting and plugging the second water inlet hole 303, the diameter of the limiting member 900 is greater than that of the second water inlet hole 303, and the height of the limiting member 900 is higher than the lowest position of the first water inlet hole 302. When the water bubble pressure in the second chamber 402 reaches the required pressure, the pressure relief device 500 abuts against the limiting member 900, the limiting member 900 plugs the second water inlet hole 303 to limit the water bubble in the first chamber 401 from entering the second chamber 402, and ensures that the water bubble in the second chamber 402 is always at a constant pressure. When the water bubble pressure in the second chamber 402 decreases, the water bubble in the first water inlet hole 302 enters the first chamber 401, and the kinetic energy of the water bubble drives the pressure relief device 500 to move in the positive direction of the y axis, so that the pressure relief device 500 is separated from the limiting member 900, and the water bubble enters the second chamber 402 from the first chamber 401.

[0088] In the embodiment, the limiting member 900 is in the shape of a cylinder and arranged on the pressure relief device 500. The cylindrical pressure relief device 500 is provided with a water passage hole in communication with the second water inlet hole 303, and when the cylindrical limiting device abuts against the bottom edge of the valve body 301, the second water inlet hole 303 is plugged. The liquid can be pure water or other flavored drinking water, and the gas can be carbon dioxide gas.
