[0043] The following combination Figures 1-14 , the inflation component, bubble water machine and household appliance provided by the embodiments of the invention are described in detail through specific embodiments and their application scenarios.

[0044] In the first aspect, Figure 1 、 Figure 2 and Figure 8 As shown, an embodiment of the present invention provides an inflation component, which is applied to a sparkling water machine. The inflation component 2 includes: an inflation end cover 21, an inflation tube 22 and a safety valve 24; The charging end cap 21 has a charging port 211, which is used to be sealed and connected to the water bottle 200; the charging tube 22 is provided on the charging end cap 21, which is used to communicate with the gas cylinder 100, and the charging tube 22 is inserted into the charging port 211 and can extend into the water bottle 200; the safety valve 24 is provided on the charging end cap 21 and is in communication with the charging port 211; Among them, the safety valve 24 includes: The safety valve chamber 2401 and the communication port 2402, the exhaust port 2403 and the regulating port 2404 communicated with the safety valve chamber 2401, the communication port 2402 communicates with the charging port 211; An adjustable member 241 , at least a portion of the adjustable member 241 being movably disposed in the adjustment opening 2404 ; The sealing plug body 242 is disposed in the safety valve cavity 2401 , and the first end of the sealing plug body 242 is used to seal the communication port 2402 ; The elastic element 243 is arranged in the safety valve cavity 2401 and abuts between the second end of the sealing plug body 242 and the adjustable member 241. The adjustable member 241 is used to adjust the deformation of the elastic element 243, wherein the elastic element 243 can be a spring.

[0045] It is understandable that when the water bottle 200 is inflated, most of the gas will dissolve in the water in the water bottle 200, while the undissolved gas will gather at the top of the water bottle 200, causing the air pressure in the water bottle 200 to gradually increase. When the air pressure in the water bottle 200 is greater than the pressure relief threshold of the safety valve 24 (for example, 0.4 to 0.8 MPa), the safety valve 24 opens to relieve pressure, completing the inflation of the water bottle 200 and ensuring inflation safety.

[0046] The safety valve 24 of this embodiment is based on the setting of the adjustable part 241, the sealing plug body 242 and the elastic element 243, so that the safety valve 24 is a safety valve that can adjust the pressure relief threshold. The user can flexibly adjust the concentration of the prepared bubble water by adjusting the pressure relief threshold of the safety valve 24.

[0047] For the above-mentioned safety valve 24, by controlling the movement of the adjustable part 241 relative to the adjustment port 2404, the setting depth of the adjustable part 241 in the adjustment port 2404 can be changed. Since the elastic element 243 abuts between the sealing plug body 242 and the adjustable part 241, when the setting depth of the adjustable part 241 in the adjustment port 2404 changes, the deformation of the elastic element 243 will change accordingly, that is, the elastic force of the elastic element 243 on the sealing plug body 242 changes, thereby realizing the adjustment of the pressure relief threshold of the safety valve 24.

[0048] In actual application, when the water bottle 200 is inflated, when the air pressure in the water bottle 200 is greater than the elastic force of the elastic element 243 on the sealing plug body 242 (for example, 0.4~0.8MPa), the sealing plug body 242 opens the connecting port 2402, and the gas in the water bottle 200 enters the safety valve cavity 2401 through the connecting port 2402, and is then discharged from the exhaust port 2403, that is, the safety valve 24 opens to relieve pressure. At this time, the inflation is completed, and the pressure in the water bottle 200 is equal to the elastic force of the elastic element 243 in the safety valve 24 on the sealing plug body 242, wherein the elastic force of the elastic element 243 on the sealing plug body 242 is adjustable within the range of 0.4~0.8MPa.

[0049] The inflation tube 22 is detachably mounted on the inflation end cap 21. The first end of the inflation tube 22 can be connected to the gas cylinder 100 through the adapter tube 4. The second end of the inflation tube 22 is used to extend into the water bottle 200 to ensure that the gas filled through the inflation tube 22 directly contacts the water in the water bottle 200, thereby facilitating the dissolution of the filled gas in the water.

[0050] In practical applications, the gas stored in the gas cylinder 100 is typically carbon dioxide, and the water in the water bottle 200 can be drinking water or a beverage, such as juice, soda water, or tea. In some scenarios, the gas stored in the gas cylinder 100 can also be nitrogen, and the water in the water bottle 200 can be coffee. Nitrogen can be injected into the coffee to improve its flavor and taste.

[0051] The inflation component 2 shown in the present invention realizes the integrated design of the inflation part of the bubble water machine by arranging the inflation tube 22 and the safety valve 24 based on the inflation end cover 21, simplifies the design structure of the bubble water machine, and when the water bottle 200 is inflated, the pressure relief of the safety valve 24 can be used to conveniently control the inflation process of the water bottle 200. The user can adjust the deformation of the elastic element 243 through the adjustable part 241 according to actual needs to change the pressure relief threshold of the safety valve 24, thereby achieving the purpose of flexibly adjusting the concentration of the prepared bubble water.

[0052] In some embodiments, as Figure 4 As shown, the adjustable member 241 includes: a valve head 2411 and a driving portion 2412; The valve head 2411 is movably disposed in the regulating port 2404 and abuts against the elastic element 243 ; the driving portion 2412 is connected to the valve head 2411 , and the driving portion 2412 is used to drive the valve head 2411 to move to adjust the position of the valve head 2411 relative to the regulating port 2404 .

[0053] It can be understood that by configuring the adjustable part 241 as a valve head 2411 and a driving part 2412, it is convenient to drive the valve head 2411 to move in the adjustment port 2404 through the driving part 2412, so as to control the deformation of the elastic element 243 through the valve head 2411, thereby realizing the adjustment of the pressure relief threshold of the safety valve 24.

[0054] Exemplarily, the driving portion 2412 may be a screw mechanism connected to the valve head 2411 to precisely control the movement stroke of the valve head 2411 in the regulating port 2404 .

[0055] For example, Figure 4 As shown, the driving part 2412 can also be a lever, and the valve head 2411 is threadedly connected to the regulating port 2404. The lever is used to drive the valve head 2411 to rotate relative to the regulating port 2404, so that the valve head 2411 moves relative to the regulating port 2404.

[0056] In actual application, the first end of the lever can be connected to the valve head 2411, and the operator can hold the second end of the lever to apply force to the lever, so that the lever drives the valve head 2411 to rotate relative to the regulating port 2404. Since the valve head 2411 and the regulating port 2404 are threadedly connected, when the valve head 2411 rotates relative to the regulating port 2404, the valve head 2411 will also move axially relative to the regulating port 2404. This design saves time and effort, and the operator can conveniently adjust the position of the valve head 2411 in the regulating port 2404 according to actual needs.

[0057] In some embodiments, as Figure 4 As shown, in order to facilitate the control of the rotation of the valve head 2411 through the shifting rod, a gear ring 24121 is formed on the shifting rod, and a gear 24111 is formed on the valve head 2411. The gear ring 24121 is sleeved on the outside of the gear 24111 and meshes with the gear 24111.

[0058] It can be understood that since the ring gear 24121 and the gear 24111 are used to realize the transmission connection between the lever and the valve head 2411, according to actual needs, after the lever is used to adjust the installation position of the valve head 2411 relative to the regulating port 2404, it is convenient to adaptively set the layout position of the lever relative to the valve head 2411 according to the installation structure on the outer shell of the bubble water machine, so that the lever can be extended out of the outer shell for user operation, that is, based on the meshing setting of the ring gear 24121 and the gear 24111, it is convenient to set the distribution posture of the lever according to needs, so that the user can install the outer shell of the bubble water machine.

[0059] In actual application, the user can control the valve head 2411 to rotate within an angle range of 0° to 120° through the lever, so that the pressure relief threshold of the safety valve 24 can be adjusted within the range of 0.4 to 0.8 MPa; for example, when the valve head 2411 is in the initial position, the pressure relief threshold of the safety valve 24 can be set to 0.4 MPa; when the lever controls the valve head 2411 to rotate 60°, the pressure relief threshold of the safety valve 24 can be adjusted to 0.6 MPa according to the position of the valve head 2411; when the lever controls the valve head 2411 to rotate 120°, the pressure relief threshold of the safety valve 24 can be adjusted to 0.8 MPa according to the position of the valve head 2411.

[0060] In some examples, the ring gear 24121 can be further configured as a ratchet sleeve, which is engaged with the gear 24111 , so that the rotation of the gear 24111 can be conveniently controlled to adjust the position of the valve head 2411 in the adjustment port 2404 .

[0061] In some embodiments, as Figure 4 As shown, the regulating port 2404 and the communicating port 2402 are arranged at opposite ends of the safety valve chamber 2401, for example, the regulating port 2404 and the communicating port 2402 are arranged relative to each other up and down relative to the safety valve chamber 2401; the exhaust port 2403 is arranged on the side of the safety valve chamber 2401 and / or the exhaust port 2403 is arranged through the valve head 2411.

[0062] For example, exhaust ports 2403 are provided on the side of the safety valve chamber 2401 and the valve head 2411. This design can ensure the pressure relief effect of the safety valve 24, and when one of the exhaust ports 2403 is blocked, the other exhaust port 2403 can perform the pressure relief work normally, thereby ensuring the reliability and safety of the safety valve 24.

[0063] In some embodiments, as Figure 1 and Figure 2 As shown, the inflation component 2 further includes: a pressure relief valve 23, which is provided on the inflation end cover 21 and communicated with the inflation interface 211. The pressure relief valve 23 is used to open and relieve pressure after the water bottle 200 is completely inflated.

[0064] It is understood that the pressure relief valve 23 can be a manual pressure relief valve or an electric pressure relief valve, and this is not specifically limited. If the pressure relief valve 23 is a manual pressure relief valve, the user can control the opening and closing state of the manual pressure relief valve by pressing the valve stem of the manual pressure relief valve. If the pressure relief valve 23 is an electric pressure relief valve, the user can control the opening and closing state of the electric pressure relief valve through a human-computer interaction module connected to the electric pressure relief valve.

[0065] During the process of inflating the water bottle 200, the pressure relief valve 23 is in a closed state, and the inflation is completed when the safety valve 24 opens to release pressure. After the water bottle 200 is completely inflated, the pressure in the water bottle 200 reaches a set value, for example, 0.4 to 0.8 MPa, and the pressure relief valve 23 opens again to release pressure in the water bottle 200 to discharge the gas that is not dissolved in the water in the water bottle 200.

[0066] The inflation component 2 shown in the present invention is provided with an inflation tube 22, a safety valve 24 and a pressure relief valve 23 based on the inflation end cover 21. When the water bottle 200 is inflated, it is only necessary to ensure that the pressure relief valve 23 is in a closed state. When the safety valve 24 is opened to relieve pressure, the inflation of the water bottle 200 can be completed. When the water bottle 200 is depressurized, it is only necessary to control the pressure relief valve 23 to switch to an open state to relieve the pressure of the water bottle 200 and discharge the excess gas in the water bottle 200. This design simplifies the design structure of the bubble water machine, reduces the size of the equipment, reduces the equipment cost, and facilitates the installation and maintenance of the equipment through the integrated design of the inflation part of the bubble water machine. In actual operation, it is only necessary to control the switching state of the pressure relief valve 23 to conveniently control the inflation and pressure relief processes of the water bottle 200, thereby improving the convenience of the inflation operation.

[0067] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, the pressure relief valve 23 includes: The pressure relief valve chamber 2301 and the vent 2302, the pressure relief port 2303 and the valve stem passage 2304 communicated with the pressure relief valve chamber 2301, the vent 2302 and the inflation port 211 are communicated with each other, wherein the pressure relief valve chamber 2301, the vent 2302, the pressure relief port 2303 and the valve stem passage 2304 are all provided on the inflation end cover 21; The pressure relief valve stem 231 is movably inserted into the valve stem passage 2304. The first end of the pressure relief valve stem 231 is used to receive pressure, and the second end of the pressure relief valve stem 231 extends into the pressure relief valve cavity 2301. The first end of the pressure relief valve stem 231 extends out of the valve stem passage 2304 to receive pressure. A pressure relief sealing plug 232 is movably disposed in the pressure relief valve chamber 2301 , and a first end of the pressure relief sealing plug 232 is used to seal the vent 2302 ; The elastic member 233 is disposed in the pressure relief valve chamber 2301 and abuts between the second end of the pressure relief sealing plug 232 and the second end of the pressure relief valve stem 231 , wherein the elastic member 233 may be a spring.

[0068] It can be understood that when the water bottle 200 is inflated, the pressure relief valve stem 231 of the pressure relief valve 23 can be pressed, for example, the pressure rod 31 of the driving mechanism 3 is swung downward to press the pressure relief valve stem 231, so that the pressure relief valve stem 231 compresses the elastic member 233 so that the elastic member 233 switches to a compressed state, and the pressure relief sealing plug 232 presses the vent 2302 under the elastic force of the elastic member 233 to ensure that the vent 2302 is in a sealed state. As the water bottle 200 continues to be inflated, the air pressure in the water bottle 200 gradually increases until the pressure in the water bottle 200 reaches a set value, for example, 0.4~0.8MPa, at which time the inflation is completed.

[0069] Then, when the water bottle 200 is depressurized, the pressure on the pressure relief valve stem 231 can be released, for example, the pressure rod 31 of the driving mechanism 3 is controlled to swing upward to separate from the pressure relief valve stem 231. At this time, the elastic member 233 will return to the initial state from the compressed state, wherein the elastic member 233 can have a certain compression deformation in the initial state; because the pressure of the air pressure in the water bottle 200 on the pressure relief sealing plug 232 is greater than the elastic force of the elastic member 233 on the pressure relief sealing plug 232, the pressure relief sealing plug 232 will find it difficult to press the vent 2302, that is, a certain gap will be generated between the pressure relief sealing plug 232 and the vent 2302, so that the vent 2302 is opened, and the gas in the water bottle 200 will enter the pressure relief valve chamber 2301 through the vent 2302, and then be discharged from the pressure relief port 2303 to discharge the residual pressure caused by the undissolved gas in the water bottle 200, until the pressure of the water bottle 200 is completely relieved.

[0070] In some embodiments, as Figure 2 and Figure 3 As shown, the pressure relief valve chamber 2301 is formed in the inflation end cover 21, and the valve stem channel 2304 and the air vent 2302 are arranged at opposite ends of the pressure relief valve chamber 2301. For example, the valve stem channel 2304 and the air vent 2302 are arranged relative to each other in the upper and lower directions relative to the pressure relief valve chamber 2301, and the pressure relief port 2303 is arranged on the side of the pressure relief valve chamber 2301.

[0071] In some embodiments, as Figure 3 As shown, the pressure relief sealing plug 232 includes: a first plug body section 2321 and a second plug body section 2322; The first plug section 2321 is movably inserted into the vent 2302 , and the second plug section 2322 is movably disposed in the pressure relief valve chamber 2301 . The first end of the second plug section 2322 is connected to the first plug section 2321 , and the second end of the second plug section 2322 abuts against the elastic member 233 .

[0072] Exemplarily, the diameter of the first plug body section 2321 is smaller than the inner diameter of the vent 2302, and the diameter of the second plug body section 2322 is smaller than the inner diameter of the pressure relief valve cavity 2301; when the pressure relief valve stem 231 is pressed, the first end of the second plug body section 2322 abuts against the inner wall of the pressure relief valve cavity 2301 to circumferentially seal the vent 2302; when the pressure relief valve stem 231 loses pressure, the first end of the second plug body section 2322 separates from the inner wall of the pressure relief valve cavity 2301, so that the vent 2302 is opened.

[0073] It can be understood that when the pressure relief valve stem 231 is pressed, the pressure relief valve stem 231 will apply a force to the pressure relief sealing plug 232 through the elastic member 233 to force the first end of the second plug body section 2322 to abut against the inner wall of the pressure relief valve cavity 2301, thereby sealing the air vent 2302. At this time, the pressure relief valve 23 is in a closed state.

[0074] When the pressure relief valve stem 231 loses its pressure, due to the residual undissolved gas in the water bottle 200, the air pressure of the water bottle 200 exerts a greater pressure on the pressure relief sealing plug 232 than the elastic force of the elastic member 233 on the pressure relief sealing plug 232, which causes the pressure relief sealing plug 232 to move toward the side of the elastic member 233, causing the first end of the second plug body section 2322 to separate from the inner wall of the pressure relief valve cavity 2301, and the air vent 2302 is opened. At this time, the gas in the water bottle 200 will enter the pressure relief valve cavity 2301 through the gap between the pressure relief sealing plug 232 and the air vent 2302, and then be discharged from the pressure relief port 2303 to relieve the pressure of the water bottle 200.

[0075] In some embodiments, as Figure 2 As shown, the inflation interface 211 includes: a cap structure 2111 and a plug 2112; the cap structure 2111 is formed on the bottom wall of the inflation end cap 21 and is used to be detachably connected to the bottle mouth of the water bottle 200; the plug 2112 is located in the cap structure 2111 and is connected to the top of the cap structure 2111. The plug 2112 is used to be inserted into the bottle mouth of the water bottle 200 to circumferentially seal the bottle mouth of the water bottle 200; An air guide channel 21120 is formed in the plug 2112 , the air filling tube 22 is passed through the air guide channel 21120 , and the pressure relief valve 23 is connected to the water bottle 200 through the air guide channel 21120 .

[0076] It is understandable that the cap structure 2111 has a cover end, which is configured to be arranged downward, and the side wall of the cap structure 2111 and the peripheral wall of the bottle mouth of the water bottle 200 can be detachably connected by a threaded structure or a snap-fit ​​structure.

[0077] When the peripheral wall of the bottle mouth of the water bottle 200 is connected to the side wall of the cap structure 2111, the plug 2112 is inserted into the bottle mouth of the water bottle 200. At this time, a good seal is formed between the peripheral wall of the plug 2112 and the inner wall of the bottle mouth of the water bottle 200. This design can not only conveniently realize the installation of the bottle mouth of the water bottle 200 based on the inflation interface 211, but also ensure the sealing between the inflation interface 211 and the bottle mouth of the water bottle 200, thereby preventing air leakage during the inflation process of the water bottle 200.

[0078] Since the mouth of the water bottle 200 is usually cylindrical, the plug 2112 can be configured as a truncated cone structure. The diameter of the plug 2112 gradually increases from the top of the cap structure 2111 to the end of the cap mouth, and the diameter of the end of the plug 2112 away from the top of the cap is smaller than the inner diameter of the mouth of the water bottle 200, and the diameter of the end of the plug 2112 facing the top of the cap is larger than the inner diameter of the mouth of the water bottle 200. This design is conducive to the plug 2112 to better seal the mouth of the water bottle 200, ensuring the circumferential sealing effect between the plug 2112 and the mouth of the water bottle 200.

[0079] In some embodiments, as Figure 2 and Figure 5 As shown, the side wall of the cap structure 2111 is provided with at least two quick-connect structures 2113 along the circumferential direction. The at least two quick-connect structures 2113 are centrally symmetrically distributed with respect to the central axis of the cap structure 2111. The quick-connect structures 2113 are configured to be disposed one-to-one with the protrusions provided on the peripheral wall of the bottle mouth of the water bottle 200. The quick-connect structure 2113 includes: a guiding slope 21131, a hollow opening 21132, and a limiting portion 21133; the guiding slope 21131 is provided on the inner side of the side wall of the cap structure 2111, extending from the cover opening of the cap structure 2111 toward the cover top of the cap structure 2111, and the guiding slope 21131 is used to slidably cooperate with the protrusion of the water bottle 200 to guide the bottle opening of the water bottle 200 to be screwed into the cap structure 2111; the hollow opening 21132 passes through the side wall of the cap structure 2111 and is arranged opposite to the guiding slope 21131; the limiting portion 21133 is provided in the hollow opening 21132, and is spaced apart from the end of the guiding slope 21131 near the cover top of the cap structure 2111 along the circumference of the cap structure 2111; When the plug 2112 is inserted into the bottle mouth of the water bottle 200 , the protrusion of the water bottle 200 is limited between the side wall of the hollow opening 21132 and the limiting portion 21133 .

[0080] It can be understood that, compared with the threaded connection between the side wall of the cap structure 2111 and the peripheral wall of the bottle mouth of the water bottle 200, by providing a quick-connect structure 2113 on the side wall of the cap structure 2111, the bottle mouth of the water bottle 200 can be installed and disassembled more quickly based on the cooperation between the quick-connect structure 2113 and the protrusion at the bottle mouth of the water bottle 200.

[0081] In actual application, the side wall of the cap structure 2111 is provided with multiple quick-connect structures 2113 along the circumferential direction, and the circumferential wall of the bottle mouth of the water bottle 200 is provided with protrusions corresponding to the multiple quick-connect structures 2113. When the bottle mouth of the water bottle 200 is inserted into the cap structure 2111, by twisting the water bottle 200 counterclockwise, each protrusion on the water bottle 200 will slide along the guide inclined surfaces 21131 corresponding to each quick-connect structure 2113. Under the guidance of the guide inclined surfaces 21131, the bottle mouth of the water bottle 200 continues to rotate counterclockwise and move toward the top of the cap structure 2111 until each protrusion reaches between the side wall of the hollow opening 21132 corresponding to the corresponding quick-connect structure 2113 and the limit portion 21133. At this time, in the absence of torque, the water bottle 200 will no longer rotate clockwise or counterclockwise relative to the cap structure 2111.

[0082] Accordingly, when it is necessary to remove the bottle mouth of the water bottle 200 from the inflation interface 211, the operator can twist the water bottle 200 clockwise to force the protrusion to cross the limiting portion 21133 to separate from the side wall of the hollow opening 21132 and the limiting portion 21133, and re-reach the guide slope 21131. Under the guidance of the guide slope 21131, the bottle mouth of the water bottle 200 continues to rotate clockwise and move toward the cover end of the cap structure 2111 until the bottle mouth of the water bottle 200 is separated from the cover end of the cap structure 2111.

[0083] In the second aspect, Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, an embodiment of the present invention further provides a sparkling water machine, comprising: an air supply component 1 and the above-mentioned inflation component 2; The gas supply component 1 is used to be sealed and connected to the gas cylinder 100 , and the gas supply component 1 is communicated with the gas pipe 22 of the inflation component 2 ; wherein, the gas supply component 1 is used to control the gas cylinder 100 to supply gas to the inflation component 2 .

[0084] It can be understood that by integrating the bubble water machine into separate air supply components 1 and inflation components 2, the design structure of the bubble water machine is simplified, the equipment volume is reduced, the equipment cost is reduced, the versatility of the bubble water machine is enhanced, and the bubble water machine can be flexibly installed and arranged to adapt to different installation conditions, thereby improving the convenience of maintaining the bubble water machine.

[0085] Since the bubble water machine includes an air supply component 1, and the specific structure of the air supply component 1 refers to the above embodiment, the bubble water machine of this embodiment includes all the technical solutions of the above embodiment, and therefore has at least all the beneficial effects achieved by all the technical solutions of the above embodiment, which will not be repeated here.

[0086] In some embodiments, as Figure 11 and Figure 12 As shown, the air supply assembly 1 includes: an air supply end cover 11, a needle valve 12 and a pressure reducing valve 13; The gas supply end cover 11 has a gas supply interface 111, which is used to be sealed and connected to the gas cylinder 100; the needle valve 12 is arranged on the gas supply end cover 11 and is connected to the gas supply interface 111, and the needle valve 12 is used to trigger the gas cylinder 100 to open; the pressure reducing valve 13 is arranged on the gas supply end cover 11, and the pressure reducing valve 13 is used to connect the needle valve 12 and the inflation pipe 22.

[0087] It can be understood that, for the gas supply assembly 1, the needle valve 12 and the pressure reducing valve 13 can be configured to be integrated on the gas supply end cover 11, and the needle valve 12 can be a manual needle valve, an electric needle valve or a pneumatic needle valve. The needle valve 12 is used to trigger the one-way valve on the gas cylinder 100 to control the opening of the gas cylinder 100 during the inflation process.

[0088] The pressure reducing valve 13 can be a spring-loaded pressure reducing valve 13 or a pilot-operated pressure reducing valve 13, and there is no specific limitation on this. The pressure reducing valve 13 is used to reduce the pressure of the high-pressure airflow supplied by the gas cylinder 100 to ensure the stability of the airflow during the inflation process of the bubble water machine, reduce the impact of the high-pressure airflow on the components, and improve the safety of the equipment.

[0089] Illustratively, the sparkling water machine can be configured with a transfer tube 4, the first end of which is connected to the pressure reducing valve 13, and the second end of which is connected to the inflation tube 22. Illustratively, the transfer tube 4 can be a flexible hose or a shaped tube, without specific limitation. Illustratively, the air supply assembly 1 and the inflation assembly 2 can be spaced apart on the mounting base 32, or can be positioned at different locations on the refrigeration equipment or drinking water equipment according to actual needs.

[0090] The sparkling water machine shown in the present invention is configured with an air supply component 1, an inflation component 2 and a transfer tube 4, and the transfer tube 4 realizes the ventilation connection between the air supply component 1 and the inflation component 2. When the water bottle 200 is inflated, the needle valve 12 is used to trigger the opening of the gas cylinder 100 to ensure that the gas in the gas cylinder 100 reaches the inflation component 2 through the transfer tube 4 after being reduced in pressure by the pressure reducing valve 13, and is then injected into the water body of the water bottle 200 through the inflation pipe 22 of the inflation component 2. When the safety valve 24 is opened to release the pressure, the inflation is completed; when the water bottle 200 is depressurized, the pressure relief valve 23 of the inflation component 2 can be used to release the pressure to discharge excess gas in the water bottle 200, thereby completing the inflation and pressure relief operations of the water bottle 200 in sequence to prepare sparkling water.

[0091] In some embodiments, as Figure 6 As shown, a first interface 101 is formed on the pressure reducing valve 13, and a second interface 102 is formed on the inflation end cover 21, and the second interface 102 is connected to the inflation tube 22; the first end of the transfer tube 4 and the first interface 101 are detachably connected, and the second end of the transfer tube 4 and the second interface 102 are detachably connected. This design can conveniently realize the loading and unloading between the first end of the transfer tube 4 and the air supply component 1, and realize the loading and unloading between the second end of the transfer tube 4 and the inflation component 2. According to actual needs, a transfer tube 4 of corresponding length can be arranged between the air supply component 1 and the inflation component 2, so as to realize the flexible installation and layout of the air supply component 1 and the inflation component 2 in a complex space.

[0092] For example, in order to ensure the airtightness of the interface connection corresponding to the transfer tube 4, the first interface 101 and the second interface 102 can both be threaded interfaces, and the first end of the transfer tube 4 can be threadedly connected to the first interface 101 through a first threaded joint, and the second end of the transfer tube 4 can be threadedly connected to the second interface 102 through a second threaded joint.

[0093] In some embodiments, when inflating the water bottle 200, the pressure relief valve 23 is first controlled to close, and then the needle valve 12 is controlled to trigger the gas cylinder 100 to open; when depressurizing the water bottle 200, the needle valve 12 is first controlled to release the triggering of the gas cylinder 100 to close the gas cylinder 100, and then the pressure relief valve 23 is controlled to open to release the pressure.

[0094] It is understandable that when the water bottle 200 is inflated, by successively controlling the switching states of the pressure relief valve 23 and the needle valve 12, it is possible to ensure that the water in the water bottle 200 is stably inflated to prevent pressure relief during the inflation process.

[0095] Accordingly, when the water bottle 200 is depressurized, by successively controlling the switching states of the needle valve 12 and the pressure relief valve 23, it is possible to save gas and reliably discharge the residual pressure in the water bottle 200, thereby ensuring the service life of the air supply component 1 and the inflation component 2.

[0096] In some embodiments, when the needle valve 12 is an electric needle valve and the pressure relief valve 23 is an electric pressure relief valve, the sparkling water machine can be configured with a human-computer interaction module, for example, the human-computer interaction module is a touch screen, and the human-computer interaction module is electrically connected to the needle valve 12 and the pressure relief valve 23 respectively. The human-computer interaction module can receive control instructions to control the working status of the needle valve 12 and the pressure relief valve 23, wherein the control instructions can be voice instructions or touch screen input instructions.

[0097] For example, when the user inputs an inflation instruction to the human-computer interaction module, the human-computer interaction module first controls the pressure relief valve 23 to close according to the inflation instruction, and then controls the needle valve 12 to trigger the gas cylinder 100 to open; when the user inputs a pressure relief instruction to the human-computer interaction module, the human-computer interaction module first controls the needle valve 12 to release the triggering of the gas cylinder 100 to close the gas cylinder 100 according to the pressure relief instruction, and then controls the pressure relief valve 23 to open and relieve pressure.

[0098] In some embodiments, as Figure 6 As shown, the sparkling water machine is equipped with a driving mechanism 3, which includes a pressure rod 31. The pressure rod 31 is swingably arranged on the upper side of the air supply component 1 and the inflation component 2. For example, the pressure rod 31 is rotatably connected to a carrier such as a refrigeration device or a drinking water device to achieve the swingable arrangement on the upper side of the air supply component 1 and the inflation component 2; During the downward swing of the pressure rod 31, the pressure rod 31 first presses the pressure relief valve 23 to control the pressure relief valve 23 to close, and then presses the needle valve 12 to control the needle valve 12 to trigger the gas cylinder 100 to open. During the upward swing of the pressure rod 31, the pressure rod 31 first separates from the needle valve 12 to close the gas cylinder 100, and then separates from the pressure relief valve 23 to open the pressure relief valve 23 to release pressure.

[0099] It can be understood that the pressure rod 31 is provided with a first operating part and a second operating part, the first operating part and the pressure relief valve 23 are arranged opposite to each other, and the second operating part and the needle valve 12 are arranged opposite to each other, and the first operating part and the second operating part can both be formed as grooves or protrusions on the pressure rod 31.

[0100] The pressure rod 31 can swing between a first position and a second position. Before the water bottle 200 is inflated, the pressure rod 31 is in the first position, that is, the pressure rod 31 is at the top dead center position of the upward swing. At this time, the pressure rod 31 is tilted, and the first operating portion of the pressure rod 31 and the pressure relief valve 23 are at a first distance, and the second operating portion of the pressure rod 31 and the needle valve 12 are at a second distance, and the first distance is smaller than the second distance.

[0101] When the pressure rod 31 is in the second position, that is, the pressure rod 31 is at the bottom dead center position of the downward swing, the pressure rod 31 can be in a horizontal state or an inclined state. The first operating part of the pressure rod 31 contacts the pressure relief valve 23 to close the pressure relief valve 23, and the second operating part of the pressure rod 31 contacts the needle valve 12 to cause the needle valve 12 to trigger the gas cylinder 100 to open.

[0102] In this way, during the downward swinging of the pressure rod 31, the first operating part of the pressure rod 31 first presses the pressure relief valve 23 to control the closing of the pressure relief valve 23, and the second operating part of the pressure rod 31 then presses the needle valve 12 to control the needle valve 12 to trigger the opening of the gas cylinder 100. During the upward swinging of the pressure rod 31, the second operating part of the pressure rod 31 first separates from the needle valve 12, so that the needle valve 12 releases the opening control of the gas cylinder 100, and the first operating part of the pressure rod 31 separates from the pressure relief valve 23 again, so that the pressure relief valve 23 opens to relieve pressure.

[0103] In this way, by setting a swingable pressure rod 31, the pressure rod 31 can be used to control the pressure relief valve 23 and the needle valve 12 in a linkage manner, ensuring that the pressure relief valve 23 and the needle valve 12 operate in sequence when the water bottle 200 is inflated and depressurized, reducing the user's operating steps, thereby improving the convenience of the user's inflation operation, ensuring the inflation efficiency of the sparkling water machine, and preventing gas waste during the inflation operation.

[0104] In some embodiments, as Figure 6 As shown, the driving mechanism 3 further includes: a mounting seat 32 and an elastic support member 33; The mounting seat 32 is rotatably connected to the pressure rod 31, and the air supply component 1 and the inflation component 2 are arranged on the mounting seat 32 along the horizontal projection direction of the pressure rod 31; the elastic support member 33 is arranged between the air supply component 1 or the inflation component 2 and the pressure rod 31, and is used to control the pressure rod 31 to separate from the pressure relief valve 23 when the pressure rod 31 is not pressed.

[0105] It can be understood that the elastic support member 33 can be a spring or an elastic rod. The elastic support member 33 can be arranged on the pressure rod 31 and arranged opposite to the air supply assembly 1.

[0106] Before inflating the water bottle 200, that is, when the pressure rod 31 is not pressed, the elastic support member 33 controls the pressure rod 31 to separate from the pressure relief valve 23. At this time, the pressure rod 31 and the needle valve 12 also remain separated. The gas cylinder 100 does not receive the triggering of the needle valve 12 and remains closed, which results in no airflow in the air supply component 1 and the inflation component 2.

[0107] When the water bottle 200 is inflated, the user controls the pressure rod 31 to swing downward. The pressure rod 31 controls the pressure relief valve 23 and the needle valve 12 to operate in sequence, and also compresses the elastic support member 33 so that the elastic support member 33 is in a compressed state.

[0108] When relieving pressure from the water bottle 200, the user controls the pressure rod 31 to swing upward, and the pressure rod 31 controls the needle valve 12 and the pressure relief valve 23 to operate in sequence. After the pressure rod 31 is separated from the pressure relief valve 23, the elastic support member 33 recovers from the compressed state to the initial state. At this time, according to the supporting force provided by the elastic support member 33 to the pressure rod 31, it is ensured again that the pressure rod 31 and the pressure relief valve 23 remain separated.

[0109] In some embodiments, as Figure 6 and Figure 10 As shown, the mounting base 32 includes: a base body 321 and a support arm 322; The base body 321 includes a first mounting port 3211 and a second mounting port 3212. The air supply end cover 11 is provided through the first mounting port 3211 and connected to the base body 321. The inflation end cover 21 is provided through the second mounting port 3212 and connected to the base body 321. The support arm 322 is connected to the base body 321 and is disposed on a side of the first installation opening 3211 away from the second installation opening 3212 . The pressing rod 31 is rotatably disposed on the support arm 322 .

[0110] It is understood that the support arm 322 and the base 321 can be configured to be detachably connected, or the support arm 322 and the base 321 can also be an integrated structure. The air supply end cover 11 can be detachably connected to the base 321 via a first flange structure, and the inflation end cover 21 can be detachably connected to the base 321 via a second flange structure.

[0111] The air supply component 1 and the inflation component 2 are fixedly installed in an integrated manner based on the base body 321. By arranging the support arm 322 on the side of the air supply component 1 away from the inflation component 2, it is convenient to arrange a pressure rod 31 that can swing up and down based on the support arm 322, so that the pressure relief valve 23 and the needle valve 12 can operate in sequence when inflating and depressurizing the water bottle 200, thereby improving the convenience of the user's inflation operation.

[0112] In some embodiments, as Figure 10 As shown, the pressure rod 31 includes: a main rod 311 and a limiting head 312; The first end of the main rod 311 is rotatably connected to the mounting seat 32, and the limit head 312 is connected to the first end of the main rod 311. When the angle of the main rod 311 swinging upward or downward relative to the mounting seat 32 reaches a limit angle, the limit head 312 abuts against the mounting seat 32.

[0113] It is understandable that the elastic support member 33 of the driving mechanism 3 is connected to the main rod 311 , and the main rod 311 may be provided with a first operating portion opposite to the pressure relief valve 23 and a second operating portion opposite to the needle valve 12 .

[0114] At the same time, the first end of the main rod 311 can be rotatably connected to the support arm 322 of the mounting seat 32 through a pin shaft. The main rod 311 is located on one side of the support arm 322, and the limit head 312 is located on the other side of the support arm 322. There is a movable gap between the limit head 312 and the support arm 322, and the movable gap is used to limit the swing relative to the support arm 322 within a limited angle range.

[0115] Exemplarily, an open groove is provided at the top of the support arm 322, the first end of the main rod 311 is passed through the open groove, and is rotatably connected to the groove wall of the open groove. Along the direction of the rotation axis of the pressure rod 31, the width of the limit head 312 is greater than the opening width of the open groove.

[0116] When the pressure rod 31 is at the upper dead center position for upward swing, the lower end of the limit head 312 abuts against the support arm 322 to prevent the pressure rod 31 from continuing to swing upward relative to the mounting base 32. At this time, based on the abutment between the lower end of the limit head 312 and the support arm 322, the user can be informed that the pressure rod 31 has swung upward to the upper dead center position.

[0117] Correspondingly, when the pressure rod 31 is at the bottom dead point position of downward swing, the upper end of the limit head 312 abuts against the support arm 322 to prevent the pressure rod 31 from continuing to swing downward relative to the mounting seat 32. At this time, based on the abutment between the upper end of the limit head 312 and the support arm 322, the user can be informed that the pressure rod 31 has swung downward to the bottom dead point position. This design can also prevent the user from continuing to press the pressure rod 31 and causing the pressure relief valve 23 and the needle valve 12 to be pressed and damaged.

[0118] In some embodiments, as Figure 7 、 Figure 11 and Figure 12 As shown, the needle valve 12 is arranged on the upper side of the air supply end cover 11, the pressure reducing valve 13 is arranged on the left or right side of the air supply end cover 11, and the air supply interface 111 is arranged on the lower side of the air supply end cover 11 and is arranged opposite to the needle valve 12. Figure 11 It is shown that the pressure reducing valve 13 is arranged on the left side of the air supply end cover 11, the pressure reducing valve 13 is arranged horizontally, and the pressure reducing valve 13 is detachably connected to the air supply end cover 11.

[0119] In some embodiments, as Figure 9 and Figure 12 As shown, the gas supply interface 111 is used to be sealed and connected to the gas cylinder 100 provided with a one-way valve; the needle valve 12 includes a needle valve cavity 121 and a valve needle 122. The needle valve cavity 121 is formed in the gas supply end cover 11 and is connected to the pressure reducing valve 13. The valve needle 122 is movably inserted in the needle valve cavity 121. The valve needle 122 can move toward the gas supply interface 111 when pressed to trigger the one-way valve to open.

[0120] Exemplarily, the needle valve chamber 121 of the needle valve 12 is vertically arranged in the air supply end cover 11 , the upper port of the needle valve chamber 121 is formed on the upper surface of the air supply end cover 11 , and the lower port of the needle valve chamber 121 is connected to the air supply interface 111 .

[0121] The valve needle 122 of the needle valve 12 includes a first rod segment, a second rod segment and a limiting end, which are connected in sequence. The diameter of the first rod segment is smaller than the diameter of the second rod segment, and the diameter of the second rod segment is smaller than the diameter of the limiting end. The limiting end is exposed at the upper port of the needle valve cavity 121 and is used to abut against the upper surface of the air supply end cover 11. The diameter of the second rod segment matches the inner diameter of the needle valve cavity 121, and a sliding seal is achieved between the peripheral wall of the second rod segment and the inner wall of the needle valve cavity 121. The pressure reducing valve 13 is connected to the area of ​​the needle valve cavity 121 corresponding to the first rod segment.

[0122] In actual use, when the mouth of the gas cylinder 100 is mounted on the gas supply interface 111, the lower end of the valve needle 122 (the end of the first rod segment away from the second rod segment) abuts the one-way valve at the mouth of the gas cylinder 100. At this time, the limiting end of the valve needle 122 is separated from the upper surface of the gas supply end cap 11. When the valve needle 122 is pressed, for example, when the limiting end of the valve needle 122 is pressed by the pressure rod 31, the valve needle 122 moves toward the gas supply interface 111, triggering the one-way valve to open, allowing the gas in the gas cylinder 100 to be discharged through the one-way valve and then flow to the inflation assembly 2 through the needle valve 12 and the pressure reducing valve 13 in sequence.

[0123] In some embodiments, as Figure 12 、 Figure 13 and Figure 14 As shown, the pressure reducing valve 13 includes: The pressure reducing valve chamber 1301 and the air inlet channel 1302 and the air outlet 1303 communicated with the pressure reducing valve chamber 1301 . The air inlet channel 1302 communicates with the needle valve 12 . A throttle port 13021 is provided in the air inlet channel 1302 . The elastic member 131 is disposed in the pressure reducing valve chamber 1301 and can be a spring; The valve core assembly 132 includes a core body 1321 and a throttling element 1322. The core body 1321 is movably arranged in the pressure-reducing valve chamber 1301. The core body 1321 abuts against the inner wall of the pressure-reducing valve chamber 1301 through the elastic component 131. The throttling element 1322 is passed through the throttling port 13021 and can move relative to the throttling port 13021 following the core body 1321. The throttling element 1322 and the throttling port 13021 cooperate to control the flow of gas entering the pressure-reducing valve chamber 1301.

[0124] It can be understood that the air inlet channel 1302 is arranged at the first end of the pressure reducing valve chamber 1301, the core body 1321 is arranged close to the first end of the pressure reducing valve chamber 1301, the elastic member 131 is abutted between the core body 1321 and the second end of the pressure reducing valve chamber 1301, and the air outlet 1303 is arranged on the side of the pressure reducing valve chamber 1301; wherein, an exhaust chamber for connecting the air inlet channel 1302 and the air outlet 1303 is formed between the core body 1321 and the first end of the pressure reducing valve chamber 1301, and a sliding seal is achieved between the peripheral wall of the core body 1321 and the inner wall of the pressure reducing valve chamber 1301, for example, the core body 1321 is in sliding contact with the inner wall of the pressure reducing valve chamber 1301 through a Y-type seal to ensure the sealing of the exhaust chamber.

[0125] For the valve core assembly 132, the part of the throttling element 1322 extending into the pressure reducing valve chamber 1301 can be directly connected to the core body 1321. For example, the part of the throttling element 1322 extending into the pressure reducing valve chamber 1301 is threadedly connected to the middle part of the core body 1321. The part of the throttling element 1322 extending into the pressure reducing valve chamber 1301 can also be connected through other transition structures to enable the throttling element 1322 to follow the core body 1321 to move relative to the throttling port 13021. Since the gap between the inner wall of the throttle port 13021 and the peripheral wall of the throttle element 1322 is small at the throttle port 13021, the gas output from the gas cylinder 100 has a large pressure loss when passing through the gap between the throttle port 13021 and the throttle element 1322. When the high-pressure gas passes through the throttle port 13021 and reaches the pressure reducing valve chamber 1301, it will be converted into low-pressure gas and then discharged from the gas outlet 1303, that is, the pressure reducing valve 13 realizes the pressure reducing output of the gas.

[0126] The throttling element 1322 has a changing shape along its axial direction, so that when the throttling element 1322 moves relative to the throttling port 13021, the size of the gap between the throttling element 1322 and the throttling port 13021 changes, thereby enabling the flow of gas entering the pressure reducing valve chamber 1301 to be controlled based on the mutual cooperation between the throttling element 1322 and the throttling port 13021.

[0127] Considering that the pressure reducing valve 13 controls the pressure reduction of the airflow output by the gas cylinder 100, it can be set that the gap between the throttling element 1322 and the throttling port 13021 gradually decreases when the valve core assembly 132 moves toward one side of the elastic member 131.

[0128] like Figure 9 and Figure 12As shown, when the gas cylinder 100 is not opened, that is, when no gas flows into the pressure reducing valve chamber 1301 from the air inlet channel 1302, the elastic force of the elastic member 131 on the core body 1321 is greater than the pressure of the exhaust chamber between the core body 1321 and the first end of the pressure reducing valve chamber 1301. At this time, the core body 1321 is in a position close to the first end of the pressure reducing valve chamber 1301.

[0129] When the gas cylinder 100 is opened, the gas output by the gas cylinder 100 enters the exhaust chamber corresponding to the pressure reducing valve chamber 1301 through the gap between the throttle port 13021 and the throttle element 1322. When the pressure of the gas is relatively high, the core 1321 will move toward the side of the elastic component 131 under the action of the pressure of the gas in the exhaust chamber, that is, the core 1321 will move to a position away from the first end of the pressure reducing valve chamber 1301. During this process, the gap between the throttle element 1322 and the throttle port 13021 gradually decreases, and the pressure reducing effect of the pressure reducing valve 13 on the gas gradually increases, so that the gas pressure in the exhaust chamber is reduced until the elastic force of the elastic component 131 on the core 1321 and the pressure of the gas pressure in the exhaust chamber on the core 1321 reach a balance, and the core 1321 no longer drives the throttle element 1322 to move relative to the throttle port 13021, ensuring that the pressure reducing valve 13 can stably achieve gas pressure reduction output with corresponding pressure reducing parameters in this state.

[0130] Correspondingly, when the air pressure in the exhaust chamber is relatively low, that is, when the air pressure in the exhaust chamber is less than the elastic force of the elastic member 131, the core 1321 will drive the throttling element 1322 to move toward the side away from the elastic member 131 until it stops moving when a new force balance is reached.

[0131] In actual application, when the air outlet 1303 is blocked or other faults occur, the air pressure in the exhaust chamber corresponding to the pressure reducing valve chamber 1301 will increase instantly, and the core 1321 will drive the throttling element 1322 to move toward the side of the elastic component 131 until the gap between the throttling element 1322 and the throttling port 13021 is reduced to zero, that is, the throttling element 1322 will block the throttling port 13021 to ensure that low pressure is maintained in the exhaust chamber, so that the pressure applied to the core 1321 by the exhaust chamber is always equal to the elastic force of the elastic component 131, thereby preventing the continuous output of high-pressure airflow and avoiding damage to the outlet device.

[0132] In some embodiments, as Figure 13 As shown, the first end of the core 1321 abuts against the elastic member 131 , and the second end of the core 1321 is connected to the throttling element 1322 .

[0133] For example, a threaded hole is provided in the middle of the second end of the core body 1321 , and a threaded joint is formed on one end of the throttling element 1322 facing the core body 1321 , and the threaded joint is threadedly connected to the threaded hole.

[0134] For example, a peripheral wall of the throttling element 1322 at one end facing the core body 1321 is further provided with an annular protrusion, which is arranged close to the threaded joint and contacts the core body 1321 .

[0135] When the gas pressure is too high and causes the throttling element 1322 to block the throttling port 13021, the annular protrusion will abut against the core body 1321 to prevent the connection between the threaded joint on the throttling element 1322 and the core body 1321 from failing, thereby protecting the entire throttling element 1322.

[0136] In some embodiments, as Figure 13 and Figure 14 As shown, the throttling element 1322 includes: a connecting rod 13221 and a conical head 13222; The first end of the connecting rod 13221 is connected to the second end of the core body 1321 , and the conical head 13222 has a conical head end disposed toward the throttle port 13021 , and the conical head end is connected to the second end of the connecting rod 13221 .

[0137] It can be understood that the diameter of the connecting rod 13221 is smaller than the diameter of the throttle port 13021, and the diameter of the connecting rod 13221 is equal to the diameter of the end of the cone head close to the throttle port 13021. The diameter of the cone head end gradually increases from the end of the cone head end close to the throttle port 13021 to the end of the cone head end away from the throttle port 13021.

[0138] In this way, in the process of the valve core assembly 132 moving toward one side of the elastic member 131, the connecting rod 13221 drives the conical head 13222 to move toward the throttle port 13021, and the end of the conical head end close to the throttle port 13021 (the end with the smaller diameter of the conical head end) is gradually inserted into the throttle port 13021. Since the conical head end is based on the inclined surface and cooperates with the inner wall of the throttle port 13021, in the process of the conical head end gradually being inserted into the throttle port 13021, the gap between the throttle element 1322 and the throttle port 13021 gradually decreases.

[0139] In some embodiments, an elastic sealing ring 1112 is provided on the side of the throttle port 13021 away from the pressure reducing valve chamber 1301. When the throttle element 1322 blocks the throttle port 13021, the elastic sealing ring 1112 is used to seal with the peripheral wall of the conical head 13222 to ensure the sealing between the throttle port 13021 and the throttle element 1322.

[0140] In some embodiments, as Figure 14 As shown, the valve core assembly 132 further includes: a core seat 1323 and an elastic compression member 1324; The core seat 1323 is movably mounted on the core body 1321. The throttling element 1322 is connected to the core seat 1323. The throttling element 1322 contacts the core body 1321 at one end thereof facing the core body 1321. The elastic compression member 1324 is disposed in the pressure reducing valve chamber 1301 and abuts between the inner wall of the pressure reducing valve chamber 1301 and the core seat 1323. In the process of the core body 1321 moving toward one side of the elastic component 131, the elastic compression member 1324 drives the core seat 1323 to drive the throttling element 1322 to move toward the core body 1321; in the process of the core body 1321 moving toward the side away from the elastic component 131, the core body 1321 and the throttling element 1322 abut against each other to drive the throttling element 1322 to move.

[0141] It can be understood that the throttle port 13021 is arranged at the first end of the pressure reducing valve chamber 1301, the core body 1321 is arranged close to the first end of the pressure reducing valve chamber 1301, the elastic member 131 is abutted between the core body 1321 and the second end of the pressure reducing valve chamber 1301, and the air outlet 1303 is connected to the pressure reducing valve chamber 1301 through a gas channel; wherein, an exhaust chamber for connecting the air inlet channel 1302 and the air outlet 1303 is formed between the core body 1321 and the first end of the pressure reducing valve chamber 1301.

[0142] A receiving groove is provided on the side of the core body 1321 away from the elastic component 131, and the groove of the receiving groove is set toward the throttle port 13021. The core seat 1323 is movably set in the receiving groove, for example, the receiving groove is set horizontally, and the peripheral wall of the core seat 1323 slides with the groove wall of the receiving groove.

[0143] Core seat 1323 is formed with a through hole, into which the central portion of throttling element 1322 is mounted. The end of core seat 1323 facing away from elastic compression member 1324 is spaced from the bottom of the accommodating groove, while the end of throttling element 1322 facing core body 1321 contacts a positioning groove provided at the bottom of the accommodating groove. Elastic compression member 1324 can be a compression spring, which is sleeved around the outside of throttling element 1322 and abuts between the inner wall of the first end of pressure reducing valve chamber 1301 and core seat 1323.

[0144] When the gas cylinder 100 is opened, the gas output by the gas cylinder 100 enters the exhaust chamber corresponding to the pressure reducing valve chamber 1301 through the gap between the throttle port 13021 and the throttling element 1322. When the pressure of the gas is relatively high, the core 1321 will move toward one side of the elastic member 131 under the action of the pressure of the gas in the exhaust chamber. At this time, the core 1321 has a tendency to separate from the throttling element 1322. Since the elastic compression member 1324 abuts between the inner wall of the pressure reducing valve chamber 1301 and the core seat 1323, the elastic compression member 1324 will drive the core seat 1323 to drive the throttling element 1322 toward the core 1321, ensuring that the throttling element 1322 moves toward One end of the core 1321 remains in contact with the core 1321 during the movement, that is, the throttling element 1322 follows the core 1321 to move toward one side of the elastic component 131. During this process, the gap between the throttling element 1322 and the throttle port 13021 gradually decreases, and the pressure reducing effect of the pressure reducing valve 13 on the gas gradually increases, so that the air pressure in the exhaust chamber decreases until the elastic force of the elastic component 131 on the core 1321 and the pressure of the air pressure in the exhaust chamber on the core 1321 reach a balance, and the throttling element 1322 no longer moves relative to the throttle port 13021, ensuring that the pressure reducing valve 13 can stably achieve gas pressure reduction output with corresponding pressure reducing parameters in this state.

[0145] Correspondingly, when the air pressure in the exhaust chamber is relatively low, that is, when the air pressure in the exhaust chamber is less than the elastic force of the elastic member 131, the core 1321 will drive the throttling element 1322 to move toward the side away from the elastic member 131 until it stops moving when a new force balance is reached.

[0146] Based on the above design structure of the valve core assembly 132, the pressure reducing valve 13 has the following protection mechanism during operation: when the air outlet 1303 is blocked or closed, the air pressure in the exhaust chamber corresponding to the pressure reducing valve chamber 1301 will increase instantly, thereby pushing the core body 1321 to move toward one side of the elastic component 131, and the throttling element 1322 will correspondingly follow the core body 1321 to move under the drive of the elastic compression member 1324 until the throttling element 1322 blocks the throttling port 13021. Compared with directly rigidly connecting the core body 1321 and the throttling element 1322, this design can not only protect the throttling element 1322 and prevent the instantaneous movement of the throttling element 1322 driven by the core body 1321 from causing damage to the throttling element 1322 and the throttling port 13021, but also use the throttling element 1322 to block the throttling port 13021 to prevent the continuous output of high-pressure airflow and damage to the outlet device.

[0147] In some embodiments, as Figure 14As shown, the air supply assembly 1 also includes a safety protection valve 14, which is arranged on the air supply end cover 11 and is connected to the pressure reducing valve chamber 1301; when the seal between the throttling element 1322 and the throttle port 13021 fails, the safety protection valve 14 is used to provide pressure relief protection for the pressure reducing valve 13.

[0148] It can be understood that the safety protection valve 14 includes a cavity, a safety valve spring and a safety valve core. The cavity has an air inlet end and a pressure relief end. The safety valve spring and the safety valve core are both arranged in the cavity. The safety valve core is used to seal at the air inlet end, and the safety valve spring abuts between the safety valve core and the pressure relief end; wherein, the air inlet end is connected to the pressure reducing valve cavity 1301 through an air channel arranged in the air supply end cover 11, and the pressure relief end is used to connect the cavity of the safety protection valve 14 with the atmospheric environment.

[0149] If the seal between throttle element 1322 and throttle opening 13021 fails, even if throttle element 1322 closes throttle opening 13021, high-pressure gas will slowly leak into pressure-reducing valve chamber 1301 of pressure-reducing valve 13 along the gap between throttle element 1322 and throttle opening 13021, and then be discharged from gas outlet 1303 of pressure-reducing valve 13, causing the pressure-reducing function of pressure-reducing valve 13 to fail. The high-pressure gas discharged through pressure-reducing valve 13 may cause significant damage to the outlet components. However, by providing a safety valve 14 in this embodiment, pressure relief can be provided through safety valve 14 when the air pressure within pressure-reducing valve chamber 1301 exceeds the pressure relief threshold of safety valve 14 (e.g., 1 MPa). This ensures the safety of subsequent outlet components of pressure-reducing valve 13 in the event of a seal failure between throttle element 1322 and throttle opening 13021.

[0150] In some embodiments, as Figure 9 and Figure 12 As shown, in order to achieve a sealed connection between the gas supply interface 111 and the bottle mouth of the gas cylinder 100, the gas supply interface 111 may include: an interface groove 1111 and a sealing ring 1112; The interface groove 1111 is formed on the bottom wall of the gas supply end cover 11, the bottom of the interface groove 1111 is connected to the needle valve 12, and the groove wall of the interface groove 1111 is threadedly connected to the bottle mouth of the gas cylinder 100. For example, the groove wall of the interface groove 1111 is provided with an internal thread, and the interface groove 1111 can be threadedly connected with the external thread provided at the bottle mouth of the gas cylinder 100 based on the internal thread; the sealing ring 1112 is provided at the bottom of the interface groove 1111, and the sealing ring 1112 is used to seal the port of the bottle mouth.

[0151] In a third aspect, the present invention further provides a household appliance, comprising: an appliance body and the above-mentioned bubble water machine, wherein the bubble water machine is arranged on the appliance body, and the appliance body is a refrigeration device or a drinking water device.

[0152] It is understandable that, according to actual needs, the air supply component 1 and the inflation component 2 of the sparkling water machine can be set at different positions of the electrical appliance body, the refrigeration equipment can be a refrigerator, freezer or ice maker, and the drinking water equipment can be a desktop water dispenser or a water purifier.
