Description

Technical Field

[0001] This application relates to the field of pipeline machine technology, and in particular to a pipeline machine. Background Technology

[0002] A piped water dispenser (also known as a water purifier) ​​is a device used in conjunction with a water purifier. Its main function is to heat or cool the purified water obtained from the water purifier before providing it to the user. Because it does not have an independent water purification function, it needs to be used with a water purifier or bottled water. Current piped water dispensers only have heating and cooling functions, making their functionality relatively limited. For example, Chinese patent CN104433795B discloses a piped water dispenser that includes a water inlet unit, a hot water outlet unit, and an ice water outlet unit, but it can only provide hot and ice water. Utility Model Content

[0003] The purpose of this application is to provide a pipeline machine.

[0004] The embodiments of this application adopt the following technical solution: a pipeline machine, comprising:

[0005] A water inlet module includes a drinking water inlet, through which drinking water is introduced into the water inlet module;

[0006] A room temperature water and hot water outlet module is connected to the water inlet module, and the room temperature water and hot water outlet module is used to provide room temperature water and hot water;

[0007] An ice water outlet module is connected to the water inlet module, and the ice water outlet module is used to produce ice water;

[0008] A sparkling water dispensing module includes an aeration device and a mixing tank. The mixing tank is connected to the aeration device and the outlet of the ice water dispensing module, respectively. The gas in the aeration device is mixed with the ice water produced by the ice water dispensing module in the mixing tank to produce ice sparkling water.

[0009] The water dispenser in this embodiment can provide room temperature water, hot water, ice water, and sparkling water, offering relatively diverse functions.

[0010] In some embodiments, the sparkling water outlet module is also connected to the outlet of the water inlet module or the outlet of the room temperature water and hot water outlet module, and the gas in the aeration device is mixed with warm water in the mixing tank to produce room temperature sparkling water. This water dispenser can also produce room temperature sparkling water, further improving the functionality of the water dispenser.

[0011] In some embodiments, the water dispenser further includes a first valve body, which is a first three-way solenoid valve. The first port of the first three-way solenoid valve is connected to the outlet of the water inlet module, the second port of the first three-way solenoid valve is connected to the inlet of the ambient temperature and hot water outlet modules, and the third port of the first valve body is connected to the inlet of the chilled water outlet module. By controlling the opening of different ports of the first valve body, it is possible to control whether the water inlet module supplies water to the ambient temperature and hot water outlet modules or to the chilled water outlet module.

[0012] In some embodiments, the water inlet module further includes an inlet solenoid valve, a zero-pressure pump, and a sterilization module. The drinking water inlet of the water inlet module is connected to the inlet of the inlet solenoid valve. The zero-pressure pump is connected to both the outlet of the inlet solenoid valve and the sterilization module. The sterilization module is connected to the outlet of the water inlet module to deliver sterilized drinking water to the inlet of the ice water outlet module or the inlet of the room temperature and hot water outlet modules. The zero-pressure pump of the water inlet module can reduce the pressure of the water flow when drinking water enters the zero-pressure pump, preventing malfunctions in the room temperature and hot water outlet modules due to unstable water pressure. The sterilization module can sterilize the drinking water, improving water safety.

[0013] In some embodiments, the pipeline machine further includes a water outlet section, the water outlet section having a first water outlet and a second water outlet;

[0014] The first water outlet is connected to the water outlet of the ice water outlet module and the water outlet of the bubble water outlet module;

[0015] The second water outlet is connected to the outlet of the ambient temperature and hot water outlet module, which includes a heating module. When the heating module is activated, the ambient temperature and hot water outlet module provides hot water; when the heating module is not activated, it provides ambient temperature water. Discharging water of different temperatures through different outlets avoids the water pipes being subjected to alternating hot and cold temperatures due to using a single outlet, thus preventing a reduction in their lifespan.

[0016] In some embodiments, the water dispenser further includes a second three-way solenoid valve. The first port of the second three-way solenoid valve is connected to the outlet of the chilled water outlet module, the second port of the second three-way solenoid valve is connected to the mixing tank, and the third port of the second three-way solenoid valve is connected to the first outlet of the water outlet section. By controlling the opening of different ports of the second three-way solenoid valve, the chilled water outlet module can directly supply chilled water or supply chilled water for making ice-bubble water to the mixing tank.

[0017] In some embodiments, the water dispenser further includes a water collection box disposed below the water outlet. The water collection box is used to collect water dripping from the water outlet, preventing water dripping from the water outlet from dripping directly into the water dispenser or onto the ground.

[0018] In some embodiments, the water dispenser further includes a water outlet pipe, which is connected to the chilled water outlet module, the aerated water outlet module, and the water outlet section, respectively. A check valve is provided on the water outlet pipe to prevent water from flowing back into the chilled water outlet module or the aerated water outlet module.

[0019] In some embodiments, the water dispenser further includes a housing, which includes a rear housing and a removable mounting plate. The mounting plate is installed on a wall to hang the entire water dispenser on the wall for easy water access.

[0020] In some embodiments, the gas injection device includes a gas cylinder, a valve seat, a pressure relief valve, and a pressure rod; the valve seat has a valve seat outlet, the pressure relief valve is disposed on the valve seat, and one end of the pressure rod is movably disposed on the valve seat;

[0021] The mixing tank has a tank opening with a connecting seat at the opening. The connecting seat has an ice water inlet, an air inlet, and an air outlet. The outlet of the ice water outlet module is connected to the ice water inlet. The air inlet is connected to the air outlet of the valve seat, and the air outlet is connected to the air inlet of the pressure relief valve. When the other end of the pressure rod is pressed down, the gas in the mixing tank enters the air inlet of the pressure relief valve through the air outlet, and the pressure relief valve relieves pressure on the mixing tank. The connecting seat on the gas cylinder and the valve seat on the mixing tank allow gas from the gas cylinder to enter the mixing tank for making sparkling water. The pressure generated in the mixing tank during sparkling water production can be released through the pressure relief valve. Attached Figure Description

Therefore, the specific structural and functional details claimed herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use this application in a variety of substantially any suitable detailed structures.

[0043] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this application.

[0044] To solve the problems in the background technology, combined with Figure 1 This application provides a water dispenser 100, which includes a water inlet module 500, a room temperature water and hot water outlet module 600, an ice water outlet module 700, and a sparkling water outlet module 800.

[0045] The water inlet module 500 includes a direct drinking water inlet 12, through which direct drinking water, which can be purified water, is introduced into the water inlet module 500. The water inlet module 500 can treat the direct drinking water, including processes such as pressure treatment and sterilization, to ensure that the direct drinking water discharged from the water inlet module 500 can stably and safely enter other modules.

[0046] The ambient temperature water and hot water outlet module 600 is connected to the outlet of the water inlet module 500. The ambient temperature water and hot water outlet module 600 is used to provide ambient temperature water and hot water.

[0047] The ambient temperature and hot water outlet module 600 may include a heating module 39. When the heating module 39 is activated, it heats the drinking water entering the ambient temperature and hot water outlet module 600 to provide hot water. When the heating module 39 is not activated, the ambient temperature and hot water outlet module 600 can directly provide ambient temperature water. Ambient temperature water is drinking water that has not been heated by the heating module 39. The ambient temperature and hot water outlet module 600 can provide both ambient temperature and hot water according to user needs, improving the functionality of the water dispenser 100 and meeting user requirements.

[0048] Whether the heating module 39 is activated can be controlled by button 5 on the control panel of the pipeline machine 100.

[0049] The chilled water outlet module 700 is also connected to the water inlet module 500, and is used to produce chilled water. The chilled water outlet module 700 may include a chilled water module, which can cool the drinking water entering the chilled water outlet module 700, so that the chilled water outlet module 700 can provide chilled water, improving the functionality of the water dispenser 100 and further meeting user needs.

[0050] When users need ice water, they can activate the ice water module, which cools the drinking water into ice water. The ice water module can use an ice tank.

[0051] The sparkling water outlet module 800 may include an aeration device 35 and a mixing tank 40. The mixing tank 40 is connected to the aeration device 35 and the outlet of the ice water outlet module 700, respectively. The gas in the aeration device 35 is mixed with the ice water produced by the ice water outlet module 700 in the mixing tank 40 to produce ice sparkling water.

[0052] When making sparkling water, the ice water produced by the ice water outlet module 700 can be first introduced into the mixing tank 40, and then the gas from the aeration device 35 can be introduced into the mixing tank 40; alternatively, the gas from the aeration device 35 can be introduced into the mixing tank 40 first, and then the ice water produced by the ice water outlet module 700 can be introduced into the mixing tank 40; alternatively, the ice water produced by the ice water outlet module 700 and the gas from the aeration device 35 can be introduced into the mixing tank 40 simultaneously. The gas in the aeration device 35 can be carbon dioxide gas.

[0053] The ice water output module may also include a water pump 311, which is connected to the outlet of the ice chamber to pump the ice water produced by the ice chamber into the mixing tank 40 of the sparkling water output module 800 or directly to the user.

[0054] The water dispenser 100 in this embodiment can provide room temperature water, hot water, ice water and sparkling water, and has relatively diverse functions.

[0055] In some embodiments, the sparkling water outlet module 800 is also connected to the outlet of the water inlet module 500 or the outlet of the room temperature and hot water outlet module 600. The gas in the aeration device 35 is mixed with warm water in the mixing tank 40 to produce room temperature sparkling water. For example, the outlet of the water inlet module 500 may be equipped with a third two-way solenoid valve. The inlet of the third two-way solenoid valve may be connected to the outlet of the water inlet module 500, and the two outlets of the third two-way solenoid valve may be connected to the inlet of the room temperature and hot water outlet module 600 and the inlet of the sparkling water outlet module 800, respectively.

[0056] The third two-way solenoid valve can also be installed at the outlet of the ambient temperature water and hot water outlet module 600. The inlet of the third two-way solenoid valve can be connected to the outlet of the ambient temperature water and hot water outlet module 600. One outlet of the third two-way solenoid valve can provide ambient temperature water and hot water, and the other outlet of the third two-way solenoid valve can be connected to the inlet of the aerated water outlet module 800.

[0057] The opening and closing of each valve port of the third two-way solenoid valve can be controlled according to the user's needs. When room temperature sparkling water needs to be made, the inlet valve port is opened, and the outlet valve port connected to the inlet of the sparkling water outlet module 800 can be opened.

[0058] The sparkling water outlet module 800 may also include an outlet solenoid valve 34. When the outlet solenoid valve 34 is opened, the sparkling water produced by the sparkling water outlet module 800 can be discharged from the sparkling water outlet module 800.

[0059] Of course, other methods can also be used to enable the produced warm water to enter the bubble water outlet module 800. This is only used as an example and does not constitute a limitation on the scope of protection of the claims.

[0060] The water dispenser 100 can also produce room temperature sparkling water, further enhancing its functional versatility.

[0061] Of course, the sparkling water outlet module 800 can also be connected to the outlet of the room temperature water and hot water outlet module 600, so that the hot water produced by the room temperature water and hot water outlet module 600 can enter the sparkling water outlet module 800 to produce hot sparkling water.

[0062] Specifically, the third two-way solenoid valve can also be installed at the outlet of the ambient temperature water and hot water outlet module 600. The inlet of the third two-way solenoid valve can be connected to the outlet of the ambient temperature water and hot water outlet module 600. One outlet of the third two-way solenoid valve can provide both ambient temperature water and hot water, while the other outlet can be connected to the inlet of the sparkling water outlet module 800. When hot sparkling water needs to be produced, both the inlet and outlet of the third two-way solenoid valve can be opened, allowing the hot water heated by the ambient temperature water and hot water outlet module 600 to enter the sparkling water outlet module 800.

[0063] The water dispenser 100 in this embodiment can also produce hot sparkling water, further enhancing the functionality of the water dispenser 100.

[0064] In some embodiments, the water dispenser 100 further includes a first valve body, which is a first three-way solenoid valve 310. The first valve port of the first three-way solenoid valve 310 is connected to the outlet of the water inlet module 500, the second valve port of the first three-way solenoid valve 310 is connected to the inlet of the ambient temperature and hot water outlet module 600, and the third valve port of the first valve body is connected to the inlet of the chilled water outlet module 700. By controlling the opening of different valve ports of the first valve body, it is possible to control whether the water inlet module 500 supplies water to the ambient temperature and hot water outlet module 600 or to the chilled water outlet module 700. In other words, the design of the first three-way solenoid valve 310 makes the water dispenser 100 more flexible and efficient in switching between different water outlet modes. Users can easily select ambient temperature water, hot water, or chilled water according to their needs, greatly improving the user experience.

[0065] For example, when room temperature water or hot water needs to be produced, the first valve port (inlet port) and the second valve port of the first three-way solenoid valve 310 are opened, allowing water from the inlet module 500 to enter the room temperature water and hot water outlet module 600. When ice water or ice-aerated sparkling water needs to be produced, the first valve port (inlet port) and the third valve port of the first three-way solenoid valve 310 are opened, allowing water from the inlet module 500 to enter the ice water outlet module 700.

[0066] In some embodiments, the water inlet module 500 further includes a water inlet solenoid valve 315, a zero-pressure pump 33, and a sterilization module 312. The drinking water inlet 12 of the water inlet module 500 is connected to the inlet of the water inlet solenoid valve 315, the zero-pressure pump 33 is connected to the outlet of the water inlet solenoid valve 315 and the sterilization module 312, and the sterilization module 312 is connected to the outlet of the water inlet module 500, so as to deliver the sterilized drinking water to the inlet of the ice water outlet module 700 or the inlet of the room temperature water and hot water outlet module 600.

[0067] For example, the drinking water inlet 12 of the water inlet module 500 can be connected to the drinking water inlet 12 of the water inlet solenoid valve 315 via an inlet pipe, and the inlet of the zero-pressure pump 33 can be connected to the outlet of the water inlet solenoid valve 315. When drinking water needs to be introduced into the water inlet module 500, the water inlet solenoid valve 315 can be opened. For example, the purified water inlet is connected to an under-sink water purifier or bottled purified water. The water inlet solenoid valve 315 is used to control the entry of the under-sink water purifier or bottled purified water into the water dispenser 100. When the user takes water, the water inlet solenoid valve 315 is open, and the purified water produced by the under-sink water purifier or bottled purified water can enter the water dispenser 100; when the user stops taking water, the water inlet solenoid valve 315 is closed, and the purified water produced by the under-sink water purifier or bottled purified water cannot enter the water dispenser 100. The outlet of the zero-pressure pump 33 can be connected to the sterilization module 312 to introduce pressure-reduced drinking water into the sterilization module 312 for sterilization. The sterilization module 312 can, but is not limited to, use ultraviolet sterilization. The zero-pressure pump 33 of the inlet module 500 can reduce the pressure of the water flow when drinking water enters the zero-pressure pump 33, preventing malfunctions in the room temperature and hot water outlet modules 600 due to unstable water pressure. At the same time, it applies pressure to the pure water, increasing the flow rate of water entering the room temperature and hot water outlet modules 600, preventing the heating module 39 of the room temperature and hot water outlet modules 600 from dry burning due to insufficient water. The sterilization module 312 can sterilize and disinfect the drinking water, preventing bacteria from growing in downstream components and pipelines, thus affecting the water quality and improving water safety.

[0068] The water inlet module 500 may also include a flow meter 314. The flow meter 314 may be installed on the connecting pipe between the outlet of the zero-pressure pump 33 and the sterilization module 312. The flow meter 314 is used to detect the flow rate of drinking water entering the room temperature water and hot water outlet modules 600, and to feed back the flow rate value of the drinking water to the main control unit 38 of the water dispenser 100 so as to accurately realize quantitative water dispensing and make it more convenient for users.

[0069] In some embodiments, the water dispenser 100 further includes a water outlet section 7, which has a first water outlet 701 and a second water outlet 702. The first water outlet 701 is connected to the water outlet of the ice water outlet module 700 and the water outlet of the sparkling water outlet module 800; the second water outlet 702 is connected to the water outlet of the room temperature water and hot water outlet module 600. For example, the water outlet section 7 may include two first water outlet pipes and a second water outlet pipe, one end of the first water outlet pipe having a first water outlet 701 and one end of the second water outlet pipe having a second water outlet 702. The other end of the first water outlet pipe is connected to the water outlet of the ice water outlet module 700 and the water outlet of the sparkling water outlet module 800. The other end of the second water outlet pipe is connected to the water outlet of the room temperature water and hot water outlet module 600.

[0070] The ambient temperature and hot water outlet module 600 includes a heating module 39. When the heating module 39 is activated, the ambient temperature and hot water outlet module 600 provides hot water; when the heating module 39 is not activated, the ambient temperature and hot water outlet module 600 provides ambient temperature water. The heating module 39 can be a hot water tank with a built-in electric heating device. The activation and deactivation of the electric heating device can be controlled by the main control unit 38 of the water dispenser 100. The heating module may also include a thermometer for detecting the water temperature in the hot water tank; when the water is heated to the set temperature, the electric heating device can be deactivated.

[0071] Water of different temperatures is discharged through different outlets of the water outlet section 7, avoiding the impact of alternating hot and cold temperatures on the water pipe caused by using the same outlet, which would affect the service life of the water pipe.

[0072] In some embodiments, the pipeline machine 100 further includes a second three-way solenoid valve 37, the first valve port (inlet valve port) of the second three-way solenoid valve 37 being connected to the outlet of the chilled water outlet module 700, the second valve port (outlet valve port) of the second three-way solenoid valve 37 being connected to the mixing tank 40, and the third valve port (outlet valve port) of the second three-way solenoid valve 37 being connected to the first outlet 701 of the water outlet section 7.

[0073] For example, when it is necessary to drink ice water directly, the first and third valve ports of the second three-way solenoid valve 37 can be opened so that the ice water produced by the ice water outlet module 700 can be discharged through the first outlet 701 of the outlet section 7. When it is necessary to make ice sparkling water, the first and second valve ports of the second three-way solenoid valve 37 can be opened so that the ice water produced by the ice water outlet module 700 can enter the mixing tank 40.

[0074] By controlling the opening of different ports of the second three-way solenoid valve 37, it is easy to control whether the chilled water outlet module 700 directly supplies chilled water or supplies chilled water for making ice-boiled water to the mixing tank 40. The second three-way solenoid valve 37 can be electrically connected to the main control unit 38 of the water dispenser 100, and the opening and closing actions of the second three-way solenoid valve 37 can be controlled by the main control unit 38 of the water dispenser 100.

[0075] In some embodiments, the water dispenser 100 also includes a water collection box 10, which is disposed below the water outlet 7. The water collection box 10 is used to collect water dripping from the water outlet 7, so as to prevent the water dripping from the water outlet 7 from dripping directly into the water dispenser 100 or onto the ground.

[0076] Combined again Figure 1 and Figure 2 The water dispenser includes a housing, which may include a rear shell 2, a middle frame assembly 3, a top cover 4, buttons 5, a panel 6, a front bracket 8, and an operation panel 9. The rear shell 2 is located behind the middle frame assembly 3, the decorative panel 6 is located in front of the middle frame assembly 3, and the top cover 4 is located on top of the middle frame assembly 3. The front bracket 8 passes through the panel 6 and is mounted on the middle frame assembly 3. The operation panel 9 is mounted on the front bracket 8, allowing users to set parameters such as water temperature and water volume. The top cover 4 has a button receiving cavity 401, within which the buttons 5 are installed. The aforementioned water outlet 7 can be housed within the front bracket 8.

[0077] Combination Figure 2 The water collection box 10 is detachably mounted on the machine body and is vertically spaced from the water outlet 7, with the water collection box 10 located below the water outlet 7. It is understood that the water collection box 10 is used to collect water dripping from the water outlet 7 after the user has finished taking water; in other words, the water collection box 10 serves to store water and prevent water from wetting the machine body. (See attached image) Figure 6 The water receiving box 10 is provided with a raised rib 1001. (See attached diagram.) Figure 3 The machine body is provided with a frame 14. When the water receiving box 10 is installed, the protruding rib 1001 on the water receiving box 10 is interlocked with the frame 14 on the machine body, so that the water receiving box 10 is firmly installed on the machine body.

[0078] The water container cover 11 is located above the water container 10 to support the water cup used by the user when taking water, and to facilitate the user to pour out the water stored in the water container 10 and to facilitate the cleaning of the water container 10.

[0079] The decorative panel 6 is made of glass, which makes it easier for users to wipe and clean the body compared to plastic or metal materials.

[0080] In some embodiments, the water dispenser further includes a water outlet pipe 15, which is connected to the outlet of the chilled water outlet module, the outlet of the sparkling water outlet module, and the inlet of the water outlet section. A check valve 36 may be provided on the water outlet pipe to prevent water from flowing back into the chilled water outlet module or the sparkling water outlet module.

[0081] The middle frame assembly 3 includes a sleeve 31, a middle frame 32, a pure water treatment module, a first three-way solenoid valve 310, a second three-way solenoid valve 37, a main control unit 38, and a water outlet pipe 15. The sleeve 31 is mounted on the middle frame 32, and a gas cylinder receiving cavity 3101 with a gas injection device is mounted on it. Specifically, the first three-way solenoid valve 310 and the second three-way solenoid valve 37 are one-inlet and two-outlet solenoid valves, that is, they are provided with an inlet valve A and an outlet valve B and an outlet valve C. When the AB channel is open, the AC channel is closed; when the AC channel is open, the AB channel is closed.

[0082] The purified water treatment module includes the aforementioned inlet module 500, a room temperature and hot water outlet module 600, an ice water outlet module 700, and a sparkling water outlet module 800. The inlet module 500 is connected to the room temperature and hot water outlet module 600 and the ice water outlet module 700 via a first three-way solenoid valve 310. The ice water outlet module 700 is connected to the sparkling water outlet module 800 and the outlet pipe 15 via a second three-way solenoid valve 37.

[0083] For example, in combination Figure 8 The refrigeration module 313 is used to refrigerate the purified water, and it is equipped with an inlet and an outlet (not shown in the figure). The inlet of the refrigeration module 313 is connected to the AC channel of the first three-way solenoid valve 310, the outlet of the refrigeration module 313 is connected to the inlet of the water pump 311, and the outlet of the water pump 311 is connected to the inlet of the second three-way solenoid valve 37.

[0084] The inlet of the outlet solenoid valve 34 of the sparkling water outlet module is connected to the mixing tank 40, and the outlet of the outlet solenoid valve 34 can be connected to the outlet pipeline 15 for discharging sparkling water. The opening and closing of the outlet solenoid valve 34 is controlled by the main control unit of the pipeline machine.

[0085] After purified water enters the purified water inlet module 500, it can flow into the room temperature water and hot water outlet modules 600, or into the ice water outlet module 700. After being cooled in the ice water outlet module 700, the purified water can flow into the sparkling water outlet module 800, or into the outlet pipe 15.

[0086] In some embodiments, since the water dispenser 100 does not have an independent water purification function, it needs to be used in conjunction with a water purification device or bottled water. As a terminal drinking water device, for the convenience of water access, it is generally wall-mounted or placed on a countertop or other convenient places for water access.

[0087] The water dispenser 100 of this embodiment includes the aforementioned rear shell 2. A detachable mounting plate 1 is provided on the rear shell 2. The mounting plate 1 is installed on a wall so that the entire water dispenser 100 can be hung on the wall for easy water access. Here, the wall can also be a countertop or other surface that facilitates water access.

[0088] refer to Figure 1 and Figure 7 The mounting plate 1 has two symmetrically arranged hooks 101. The surface of the rear shell 2 has two symmetrically arranged mounting platforms 201. The function of the mounting plate 1 is that when the water dispenser 100 needs to be wall-mounted, the mounting plate 1 must first be installed on the wall, and then the machine body is installed on the mounting plate 1. Specifically, the hooks 101 on the mounting plate 1 are inserted into the mounting platforms 201 on the rear shell 2, so that the machine body is reliably fixed to the wall.

[0089] In some embodiments, the gas injection device 35 includes a gas cylinder 350, a valve seat 355, a pressure relief valve 351, and a pressure rod 353; the valve seat 355 has a valve seat 355 outlet, the pressure relief valve 351 is disposed on the valve seat 355, and one end of the pressure rod 353 is movably disposed on the valve seat 355.

[0090] The mixing tank 40 has a tank opening, and a connecting seat is provided at the tank opening. The connecting seat is provided with an ice water inlet 3520, an air inlet, and an air outlet. The outlet of the ice water outlet module 700 is connected to the ice water inlet 3520. The air inlet is connected to the air outlet of the valve seat 355. The air outlet is connected to the air inlet of the pressure relief valve 351. When the other end of the pressure rod 353 is pressed down, the gas in the mixing tank 40 enters the air inlet of the pressure relief valve 351 through the air outlet, and the pressure relief valve 351 relieves pressure on the mixing tank 40.

[0091] For example, refer to Figure 4 and Figure 5 The gas injection device 35 includes a gas cylinder 350, a pressure relief valve 351, a mixing tank connection seat 352, a pressure rod 353, a valve seat 355, and a gas injection nozzle 356. The pressure relief valve 351 is mounted on the valve seat 355 and has a pressure relief valve inlet 3510. The mixing tank connection seat 352 has a mixing tank chilled water inlet 3520, a mixing tank air inlet 3521, and a mixing tank air outlet 3522. The valve seat 355 has a valve seat air outlet 3550. The mixing tank air inlet 3521 is connected to the valve seat air outlet 3550, the pressure relief valve air inlet 3510 is connected to the mixing tank air outlet 3522, and the mixing tank chilled water inlet 3520 is connected to the AC channel of the second three-way solenoid valve 37.

[0092] Valve seat 355 and mixing tank connecting seat 352 are fixed to sleeve 31. Gas cylinder 350 is fixed to valve seat 355 by threads. Gas cylinder 350 is used to store food-grade carbon dioxide gas and is located in gas cylinder receiving cavity 3101. Mixing tank 40 and gas injection nozzle 356 are both fixed to mixing tank connecting seat 352, and gas injection nozzle 356 extends into mixing tank 40 and is used to inject food-grade carbon dioxide gas into pure water.

[0093] The pressure lever 353 is movably positioned below the button 5. Pressing button 5 activates the pressure lever 353. When sparkling water is needed, pressing and holding button 5 for a period of time causes carbon dioxide gas stored in the gas cylinder 350 to flow out from the valve seat outlet 3550, enter through the mixing tank inlet 3521, and pass through the injection nozzle 356, ultimately mixing and dissolving with the purified water in the mixing tank 40 to produce sparkling water. The pressure relief valve inlet 3510 is connected to the mixing tank outlet 3522, allowing the gas pressure in the mixing tank 40 to decrease to 0.5-0.7 MPa during injection, thus ensuring that the carbon dioxide gas is fully dissolved in the mixing tank 40, resulting in a better taste for the sparkling water.

[0094] Reference Appendix Figure 3 The gas cylinder 350 has a groove 13 at the tail end, which makes it easier to install and remove the gas cylinder 350.

[0095] A connecting seat is provided on the gas cylinder 350 and a valve seat is provided on the mixing tank so that the gas in the gas cylinder 350 can enter the mixing tank for making sparkling water. The pressure generated in the mixing tank during the making of sparkling water can be released through the pressure relief valve.

[0096] Reference Appendix Figure 8 Taking sparkling water as an example, the working principle of the water dispenser in this embodiment is as follows: When the user needs to take room temperature water or hot water, the AB channel of the first three-way solenoid valve 310 is opened and the AC channel is closed. After the purified water flows through the room temperature water and hot water outlet module 600, it flows out from the room temperature water and hot water outlet 702 on the water outlet section 7. When the user needs to take ice water, the AB channel of the second three-way solenoid valve 37 is opened and the AC channel is closed. The purified water, after being cooled by the cooling module 313, flows out from the ice water outlet 701 on the water outlet section 7 via the water pump 311. When sparkling water needs to be made, after pressing the button 5, carbon dioxide gas is discharged from the gas cylinder 350 and enters the mixing tank 40 to mix with the ice water stored in the mixing tank. After the carbon dioxide gas is fully dissolved in the purified water, the water outlet solenoid valve 34 is opened, and the sparkling water is produced and flows out from the ice water outlet 701 on the water outlet section 7 via the water outlet pipe 15. The check valve 36 is designed to prevent pure water from flowing into the water outlet pipe 15 when taking room temperature or hot water.

[0097] The foregoing has described in detail several embodiments of this application, but this application is not limited to these specific embodiments. Those skilled in the art can make various variations and modifications based on the concept of this application, and all such variations and modifications should fall within the scope of protection claimed in this application.
