They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0047] This embodiment provides a functional water preparation device, such as... Figure 1 As shown, the system includes a water supply mechanism, an air supply component 30, an instantaneous mixing component 20, and a water outlet structure 40. The water supply mechanism provides water for preparing functional water. The air supply component 30 stores functional gas and supplies functional gas to the instantaneous mixing component 20. The instantaneous mixing component 20 is connected to the water supply mechanism, the air supply component 30, and the water outlet structure 40. Water and functional gas can be mixed within the instantaneous mixing component 20 to prepare functional water, which is then output through the water outlet structure 40 for user use.

[0048] Optionally, the gas stored in the gas supply component 30 can be carbon dioxide, hydrogen, or oxygen, and correspondingly, the functional water can be soda water, oxygen-enriched water, or hydrogen-enriched water. In this embodiment, carbon dioxide as the functional gas and soda water as the prepared functional water are used as examples.

[0049] In some embodiments, the water supply mechanism includes a cold water preparation component 10 for preparing cold water and supplying cold water to the instantaneous mixing component 20 to increase the concentration of functional water.

[0050] To improve user experience, the instant mixing component 20 can produce functional water instantly and continuously, eliminating the need to prepare functional water in advance and solving the problems of insufficient production and inability to use it continuously.

[0051] Specifically, such as Figures 2-5 As shown, a mixing channel 213 is formed within the instantaneous mixing component 20. The first end of the mixing channel 213 can be connected to the cold water preparation component 10 and the gas supply component 30, respectively, and the last end of the mixing channel 213 can be connected to the water outlet structure 40. During the preparation of soda water, cold water and carbon dioxide enter the mixing channel 213 and mix during the flow process. The resulting soda water is then transported to the water outlet structure 40, achieving instantaneous and continuous preparation of soda water. The amount of soda water produced can be flexibly prepared according to the user's needs, eliminating the need for an additional functional water tank to prepare and store soda water in advance, thus ensuring sufficient production to meet the user's continuous consumption requirements.

[0052] It should be noted that in the instantaneous mixing component 20, the mixing channel 213 only needs to meet the mixing requirements of cold water and carbon dioxide, and does not have the function of storing fluid. Therefore, its size can be designed to be smaller, thereby reducing the size of the instantaneous mixing component 20. This is beneficial for controlling the size of the functional water preparation device, thereby reducing the requirement for installation space and reducing costs.

[0053] To ensure continuous preparation of soda water whenever needed, the functional water preparation device also includes a valve assembly. The valve assembly works in conjunction with the cold water preparation assembly 10, the gas supply assembly 30, and the instantaneous mixing assembly 20 to control the connection or disconnection of the beginning of the mixing channel 213 with the cold water preparation assembly 10 and the gas supply assembly 30. This ensures that when the user needs to take soda water, cold water and carbon dioxide are delivered into the mixing channel 213 to achieve continuous and instantaneous preparation of soda water.

[0054] In some embodiments, the valve assembly is used to control the cold water preparation assembly 10 and the gas supply assembly 30 to be simultaneously connected to the beginning end of the mixing channel 213, so as to simultaneously introduce cold water and carbon dioxide into the mixing channel 213, thereby instantaneously preparing soda water.

[0055] In some embodiments, the instantaneous mixing component 20 further includes a first flow channel 211 and a second flow channel 212. The ends of the first flow channel 211 and the second flow channel 212 are connected to the beginning of the mixing flow channel 213. The beginning of the first flow channel 211 is used to connect to the cold water preparation component 10, and the beginning of the second flow channel 212 is used to connect to the gas supply component 30. The instantaneous mixing component 20 is provided with a mixing outlet 221 that communicates with the mixing flow channel 213 and is used to connect to the water outlet structure 40. When preparing functional water, cold water is introduced into the first flow channel 211, and carbon dioxide is introduced into the second flow channel 212, so that the cold water and carbon dioxide flow and mix in the mixing flow channel 213 to obtain soda water. The soda water is then transported to the water outlet structure 40 through the mixing flow channel 213.

[0056] To achieve simultaneous delivery of cold water and carbon dioxide, in some embodiments, such as Figure 1 As shown, the valve assembly includes a first control valve 101 and a second control valve 102. The first control valve 101 is disposed between the cold water preparation assembly 10 and the first flow channel 211, and is used to control the on / off state of the cold water preparation assembly 10 and the first flow channel 211. The second control valve 102 is disposed between the air supply assembly 30 and the second flow channel 212, and is used to control the on / off state of the air supply assembly 30 and the second flow channel 212. The first control valve 101 and the second control valve 102 can be controlled independently to open or close as needed.

[0057] In some embodiments, both the first control valve 101 and the second control valve 102 can be on / off valves to achieve on / off functions. Optionally, the first control valve 101 and the second control valve 102 can be solenoid valves to achieve automatic control of opening and closing.

[0058] In the instantaneous mixing component 20, cold water and carbon dioxide are mixed during the flow process. In order to ensure the dissolution effect of carbon dioxide in cold water, the cross-sectional area of ​​the first flow channel 211 can be gradually reduced along the flow direction of cold water to slow down the flow rate of cold water, so as to fully mix carbon dioxide and cold water.

[0059] In some embodiments, the cross-sectional area of ​​the second flow channel 212 gradually decreases along the gas flow direction to increase the gas flow rate and reduce the gas pressure, so that carbon dioxide is mixed with cold water at high speed and low pressure, which is beneficial to increase the solubility of carbon dioxide in cold water and thus increase the concentration of soda water prepared.

[0060] To improve the mixing effect of cold water and carbon dioxide, in some embodiments, the first flow channel 211 and the second flow channel 212 are arranged at an angle so that the cold water and carbon dioxide are in convection when entering the mixing flow channel 213, reducing the flow velocity and thus mixing thoroughly.

[0061] For example, the included angle between the first flow channel 211 and the second flow channel 212 can be an acute angle, a right angle, or an obtuse angle. While ensuring that both cold water and carbon dioxide flow into the mixing flow channel 213, convection is increased to improve the mixing effect.

[0062] In some embodiments, the first flow channel 211, the second flow channel 212, and the mixing flow channel 213 are arranged at an angle to each other. That is, the first flow channel 211, the second flow channel 212, and the mixing flow channel 213 are approximately Y-shaped, which increases the collision of fluids in the mixing flow channel 213 and improves the mixing effect.

[0063] Optionally, the central axis of the first flow channel 211, the central axis of the second flow channel 212, and the central axis of the mixing flow channel 213 can be set at equal angles to each other.

[0064] In some embodiments, the heights of the first flow channel 211, the second flow channel 212, and / or the mixing flow channel 213 gradually decrease from the beginning to the end. The second flow channel 212 extends downward, causing the direction of carbon dioxide entering the cold water to be downward, which is opposite to the flow direction of carbon dioxide when it overflows from the cold water. This can prevent carbon dioxide from overflowing from the cold water and is beneficial to increasing the amount of carbon dioxide dissolved. The first flow channel 211 extends from top to bottom, which allows the weight of the cold water to act as an aid to drive the flow of the cold water. The mixing flow channel 213 extends from top to bottom, which is beneficial for the cold water to carry carbon dioxide under the action of gravity and increase the amount of carbon dioxide dissolved.

[0065] In some embodiments, the instantaneous mixing assembly 20 may include a mixing chamber 201, which connects the end of the mixing channel 213 and the mixing outlet 221. By providing the mixing chamber 201, the mixed soda water can enter and generate turbulence, which facilitates more thorough mixing of carbon dioxide and cold water to form soda water. The pressure within the mixing chamber 201 pushes the soda water into the mixing outlet 221 and out. This pressure also helps to increase the solubility of carbon dioxide, thereby increasing the concentration of the soda water.

[0066] Furthermore, by setting up a mixing chamber 201, cold water sequentially passes through the first flow channel 211 and the mixing flow channel 213 before entering the mixing chamber 201. The effective flow area of ​​the cold water first decreases and then increases. According to Bernoulli's principle, when the cold water passes through the first flow channel 211, the flow rate of the cold water increases, which is beneficial for the continuous delivery of cold water in the cold water preparation component 10. When the cold water enters the mixing chamber 201 through the mixing flow channel 213, the flow rate of the cold water decreases, thus making the cold water passing through the first flow channel 211 low-pressure, low-speed cold water. This reduces the flow rate of the cold water, allowing carbon dioxide to mix fully with the cold water, improving the solubility of carbon dioxide in the cold water, and thus increasing the concentration of the soda water.

[0067] In some embodiments, the mixing chamber 201 can be a spherical cavity. Soda water entering the mixing chamber 201 through the mixing channel 213 can flow along the inner wall of the spherical cavity, increasing the turbulence effect and thereby improving the mixing effect of cold water and carbon dioxide.

[0068] It should be noted that the mixing chamber 201 is only used as a temporary storage chamber for soda water, and its volume can be set to be small. The size of the mixing chamber 201 can be much smaller than the volume of the functional water tank in the prior art, so that the overall size of the instantaneous mixing component 20 is still smaller than that of the functional water tank in the prior art.

[0069] In order to ensure that all the continuously prepared soda water can be delivered to the water outlet structure 40 for user use, in some embodiments, the mixing outlet 221 is connected to the bottom end of the mixing chamber 201, so that the soda water in the mixing chamber 201 can pass through the mixing outlet 221 under the action of gravity, avoiding the presence of residual soda water in the mixing chamber 201.

[0070] like Figure 2 and Figure 4 As shown, in some embodiments, the instantaneous mixing component 20 includes an upper shell 21, a lower shell 22, and a sealing ring. The first flow channel 211, the second flow channel 212, and the mixing flow channel 213 are all located in the upper shell 21. The mixing outlet 221 is disposed in the lower shell 22. The upper shell 21 and the lower shell 22 are fixedly connected and form a mixing cavity 201. The sealing ring is clamped between the upper shell 21 and the lower shell 22 to achieve a sealed connection between the upper shell 21 and the lower shell 22 and prevent water leakage from the mixing cavity 201.

[0071] Specifically, the upper shell 21 includes a first shell body and a first pipe and a second pipe disposed on the first shell body. A first flow channel 211 is formed in the first pipe, a second flow channel 212 is formed in the second pipe, and a mixing flow channel 213 is formed in the first shell body and communicates with the first pipe and the second pipe respectively. The first shell body may be formed with a hemispherical groove so as to cooperate with the lower shell 22 to form a mixing cavity 201.

[0072] Similarly, the lower shell 22 includes a second shell body and a third tube disposed on the second shell body. The second shell body forms a hemispherical groove, and the third tube communicates with the hemispherical groove for dispensing soda water.

[0073] Optionally, both the upper shell 21 and the lower shell 22 include flange plates arranged circumferentially around the hemispherical groove. The flange plates of the upper shell 21 and the lower shell 22 are stacked and fixed, and the sealing ring can be clamped between the two flange plates.

[0074] Alternatively, the two flanges can be fastened together with bolts and nuts for easy disassembly and replacement of the sealing ring.

[0075] Optionally, both the upper shell 21 and the lower shell 22 can be integrally molded to reduce the number of parts in the instantaneous mixing assembly 20 and facilitate assembly.

[0076] In some embodiments, a third control valve 103 is also provided between the mixing outlet 221 of the instant mixing component 20 and the water outlet structure 40. The third control valve 103 can control the opening and closing between the mixing outlet 221 and the water outlet structure 40 to prevent residual soda water in the instant mixing component 20 from dripping through the water outlet structure 40, thereby improving the user experience.

[0077] In some embodiments, the mixing outlet 221 of the instant mixing component 20 can also be connected to a wastewater pipe to discharge the residual soda water in the instant mixing component 20, thereby preventing the growth of bacteria due to the long-term retention of soda water in the instant mixing component 20.

[0078] Optionally, a one-way valve 108 is installed on the wastewater pipe to prevent backflow during the waste discharge process, thereby preventing contamination of the instantaneous mixing component 20.

[0079] In some embodiments, a booster pump 50 is provided between the cold water preparation component 10 and the first control valve 101. The booster pump 50 can pump the cold water in the cold water preparation component 10 to the instantaneous mixing component 20, thereby improving the driving effect on the cold water and ensuring stable preparation of soda water.

[0080] In some embodiments, the cold water preparation assembly 10 includes a cold water tank 11 and a refrigeration structure 12 for preparing cold water. The cold water tank 11 is provided with a clean water inlet and a cold water outlet. The clean water inlet is used to deliver clean water into the cold water tank 11, and the cold water outlet can be connected to the first flow channel 211. The refrigeration end of the refrigeration structure 12 is in heat exchange cooperation with the cold water tank 11 to reduce the temperature of the water in the cold water tank 11 in order to prepare cold water.

[0081] For example, the refrigeration structure 12 includes an evaporator 121, a compressor 122, and a condenser 123. The evaporator 121 covers the outer wall of the cold water tank 11 and is used to cooperate with the cold water tank 11 for heat exchange to transfer cooling capacity to the cold water tank 11. The compressor 122 connects the evaporator 121 and the condenser 123 and forms a circulation path for the refrigerant. The refrigerant absorbs heat from the cold water tank 11 in the evaporator 121 to lower the temperature of the water in the cold water tank 11. The refrigerant with the increased temperature heats up in the condenser 123 to lower the temperature of the refrigerant, thereby achieving cyclic refrigeration.

[0082] Optionally, the refrigeration structure 12 also includes a fan 124, which corresponds to the condenser 123 and is used to dissipate heat from the condenser 123 to reduce the temperature of the refrigerant inside the condenser 123.

[0083] In some embodiments, a temperature sensor is provided on the cold water tank 11. The temperature sensor is used to detect the temperature of the cold water in the cold water tank 11. The temperature sensor can be electrically connected to the refrigeration structure 12 through the control component to realize refrigeration temperature feedback, thereby controlling the water temperature in the cold water tank 11.

[0084] It should be noted that the control component and temperature sensor are both existing technologies. This utility model can use any type of control component and temperature sensor, and can also use any connection method to realize the electrical connection between the temperature sensor, control component and refrigeration structure 12. These will not be described in detail here.

[0085] In some embodiments, the water supply mechanism further includes a filter assembly 90, a purified water tank 70, and an instant heating module 80. The inlet end of the filter assembly 90 is connected to a water source, and the filter assembly 90 is used to filter raw water to prepare purified water. The purified water tank 70 is connected to the outlet end of the filter assembly 90 to store the prepared purified water. The purified water tank 70 includes a first purified water outlet and a second purified water outlet. The first purified water outlet is connected to the cold water preparation assembly 10 to deliver purified water into the cold water tank 11. The instant heating module 80 is connected to the second purified water outlet and is connected to the water outlet structure 40 to provide warm or hot water to the user.

[0086] In some embodiments, a first water pump is provided between the second water inlet and the instant heating module 80 to pump purified water to the instant heating module 80 to achieve the output of hot water.

[0087] It should be noted that the instant heating module 80 is existing technology, and this utility model can adopt any type of instant heating module 80, which will not be described in detail here.

[0088] To achieve zero cold water output when users access hot water, in some embodiments, a fourth control valve 104 is also provided between the instant heating module 80 and the water outlet structure 40. The fourth control valve 104 is a one-in-two-out switching valve. One port of the fourth control valve 104 is connected to the water outlet of the instant heating module 80, and the other two ports are connected to the water outlet structure 40 and the purified water tank 70, respectively. The fourth control valve 104 can allow the water output from the instant heating module 80 to either flow back to the purified water tank 70 or be output to the water outlet structure 40. When a user accesses hot water, the fourth control valve 104 first connects the water outlet of the instant heating module 80 to the purified water tank 70, allowing any residual cold water or water not heated to the preset temperature in the instant heating module 80 to flow back to the purified water tank 70, preventing the water output through the water outlet structure 40 from failing to reach the user's desired temperature. When the temperature of the water heated by the instant heating module 80 meets the user's needs, the fourth control valve 104 connects the water outlet of the instant heating module 80 to the water outlet structure 40 to provide hot water to the user.

[0089] To achieve water temperature control, temperature sensors are installed at both the inlet and outlet of the instant heating module 80. The temperature sensors are electrically connected to the instant heating module 80 and the fourth control valve 104 respectively through the control component to achieve feedback control of the heating temperature, thereby switching the state of the fourth control valve 104 according to the heated water temperature.

[0090] In some embodiments, the first control valve 101 can be a switching valve, which is connected to the booster pump 50, the first flow channel 211 and the water outlet structure 40 respectively. The switching valve can switch the working state so that the booster pump 50 can selectively connect to the first flow channel 211 or the water outlet structure 40 to deliver cold water to the water outlet structure 40 according to user needs for user convenience, or deliver cold water to the instant mixing component 20 to prepare soda water.

[0091] In some other embodiments, the switching valve can be implemented by two switching valves, as long as they can enable the connection and disconnection between the booster pump 50 and the first flow channel 211, and between the booster pump 50 and the water outlet structure 40.

[0092] In some embodiments, the purified water tank 70 includes a tank body 71 and a water level detection element 74. The tank body 71 is used to store purified water, and the water level detection element 74 is used to detect the water level of the purified water in the tank body 71 so as to replenish the purified water in the tank body 71 in a timely manner or to prevent the purified water in the tank body 71 from overflowing due to excessive amount.

[0093] Optionally, the water level detection element 74 can be a float level gauge, a capacitive level gauge, a differential pressure level gauge, an ultrasonic level gauge, or other structures capable of detecting the liquid level.

[0094] In some embodiments, the water purification tank 70 further includes a sterilization and disinfection component for sterilizing and disinfecting the interior of the tank 71 to ensure drinking water hygiene. Optionally, the sterilization and disinfection component includes a first sterilization element 72 and a second sterilization element 73, wherein the first sterilization element 72 and the second sterilization element 73 can be UV lamps to inhibit bacteria through ultraviolet light.
