Description

Technical Field

[0001] The present invention relates to the technical field of bubble water preparation, and in particular to an inflation component, a bubble water machine and a household appliance. Background Art

[0002] As people's quality of life continues to improve, sparkling water is becoming increasingly popular due to its unique taste and benefits to the human digestive system. Currently, sparkling water is commonly produced using manual or electric pump-type sparkling water machines. These machines primarily inject compressed carbon dioxide gas into a bottle, achieving a certain solubility in liquids such as water or juice.

[0003] However, in actual applications, it is found that the inflation part of existing sparkling water machines usually adopts a complex connection structure. For example, the water bottle is inflated and depressurized through multiple air pipes and pressure relief valves. The user needs to control multiple components during the inflation operation. Not only is the inflation process cumbersome and time-consuming, but the design structure of the entire inflation part is complex, resulting in a large device size, high manufacturing cost, and inconvenient installation and maintenance. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the related art. To this end, the present invention provides an inflation assembly.

[0045] The following combination Figures 1-13 , 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.

[0046] In the first aspect, Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 6 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, a switch valve 25, a pressure relief valve 23 and a driving mechanism 26; The inflatable end cap 21 has an inflatable interface 211, which is used to be sealed and connected to the water bottle 200; the inflatable tube 22 is provided on the inflatable end cap 21, and the inflatable tube 22 is inserted into the inflatable interface 211 and can extend into the water bottle 200; the switch valve 25 is used to connect the inflatable tube 22 and the gas cylinder 100; the pressure relief valve 23 is provided on the inflatable end cap 21 and is connected to the inflatable interface 211; the driving mechanism 26 is used to be connected to the switch valve 25 and the pressure relief valve 23 respectively; Among them, when inflating the water bottle 200, the driving mechanism 26 first controls the pressure relief valve 23 to be in a closed state, and then controls the switch valve 25 to be open. When depressurizing the water bottle 200, the driving mechanism 26 first controls the switch valve 25 to be closed, and then controls the pressure relief valve 23 to be in an open state.

[0047] It can be understood that, for the inflation component 2, the inflation tube 22, the switch valve 25, the pressure relief valve 23 and the driving mechanism 26 can all be integrated on the inflation end cover 21, or the inflation tube 22, the pressure relief valve 23 and the driving mechanism 26 can be integrated on the inflation end cover 21, and the switch valve 25 can be installed on the driving mechanism 26. There is no specific limitation on this.

[0048] Among them, the inflation interface 211 on the inflation end cover 21 can be a threaded interface or a snap-on interface, and there is no restriction on this, as long as the inflation interface 211 is easy to connect with the bottle mouth of the water bottle 200 and ensures the sealing between the inflation interface 211 and the water bottle 200.

[0049] Exemplarily, the pressure relief valve 23 can be a manual pressure relief valve, the switch valve 25 can be a manual gate valve, and the driving mechanism 26 can be a pressing mechanism. The pressing mechanism can control the switching status of the pressure relief valve 23 and the switch valve 25 respectively by pressing the corresponding valve stems of the pressure relief valve 23 and the switch valve 25.

[0050] Exemplarily, the pressure relief valve 23 can be an electric pressure relief valve, the switch valve 25 can be an electric switch valve, and the driving mechanism 26 can be a human-computer interaction module. For example, the human-computer interaction module is a touch screen. The human-computer interaction module is electrically connected to the pressure relief valve 23 and the switch valve 25 respectively. The user can input control instructions through the human-computer interaction module, and the human-computer interaction module responds to the control instructions to control the switching status of the pressure relief valve 23 and the switch valve 25 respectively.

[0051] During the process of inflating the water bottle 200, the pressure relief valve 23 is in a closed state. 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 to relieve the pressure in the water bottle 200 to discharge the gas that is not dissolved in the water in the water bottle 200.

[0052] At the same time, the gas tube 22 is detachably mounted on the gas end cap 21. The first end of the gas tube 22 is connected to the on-off valve 25 via the second adapter tube 4. The on-off valve 25 is connected to the gas cylinder 100 via the first adapter tube 3. The second end of the gas tube 22 is configured to extend into the water bottle 200, ensuring that the gas injected through the gas tube 22 directly contacts the water in the water bottle 200, facilitating dissolution of the injected gas in the water. Both the first adapter tube 3 and the second adapter tube 4 may be flexible tubes.

[0053] 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.

[0054] The inflatable assembly 2 shown in the present invention is provided with an inflatable tube 22 and a pressure relief valve 23 based on an inflatable end cap 21, and is provided with an on-off valve 25 and a driving mechanism 26 for controlling the on-off valve 25 and the pressure relief valve 23 in a linkage manner. When inflating the water bottle 200, it is only necessary to control the pressure relief valve 23 and the on-off valve 25 to operate in sequence through the driving mechanism 26 to complete the inflation of the water bottle 200. When depressurizing the water bottle 200, it is only necessary to control the on-off valve 25 and the pressure relief valve 23 to operate in sequence through the driving mechanism 26 to depressurize the water bottle 200 and discharge the liquid from the water bottle 200. This design simplifies the design structure of the bubble water machine, reduces the size of the equipment, reduces the cost of the equipment, and facilitates the installation and maintenance of the equipment through the integrated design of the bubble water machine's inflation part. The driving mechanism 26 is used to control the linkage of the pressure relief valve 23 and the switch valve 25 to ensure that the pressure relief valve 23 and the switch valve 25 operate in sequence when the water bottle 200 is inflated and depressurized, thereby reducing the user's operating steps, thereby improving the convenience of the user's inflation operation, ensuring the inflation efficiency of the bubble water machine, and preventing gas waste during the inflation operation.

[0055] In some embodiments, as Figure 1 、 Figure 2 and Figure 3 As shown, the driving mechanism 26 includes: a mounting seat 262 and a pressure rod 261; The mounting seat 262 is connected to the inflation end cover 21, and the switch valve 25 is provided on the mounting seat 262; the pressure rod 261 is rotatably connected to the mounting seat 262 and is rotatably provided on the upper side of the switch valve 25 and the pressure relief valve 23; like Figure 5 As shown, during the downward swinging of the pressure rod 261, for example, when the pressure rod 261 swings counterclockwise, the pressure rod 261 presses the pressure relief valve 23 and the switch valve 25 in sequence, as shown in FIG. Figure 6As shown, during the upward swinging of the pressure rod 261 , for example, when the pressure rod 261 swings clockwise, the pressure rod 261 is separated from the switch valve 25 and the pressure relief valve 23 in sequence.

[0056] It can be understood that a first mounting port 26201 and a second mounting port 26202 are provided on the mounting seat 262. The first mounting port 26201 is used to install the switch valve 25, and the second mounting port 26202 is used to install the inflation end cover 21. The pressure rod 261 is rotatably connected to the area of ​​the first mounting port 26201 on the mounting seat 262 away from the second mounting port 26202 through a hinge shaft.

[0057] The pressure rod 261 is rotatably arranged on the upper side of the pressure relief valve 23 and the switch valve 25. The pressure rod 261 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 switch valve 25 are arranged opposite to each other. The first operating part and the second operating part can both be formed as grooves or protrusions on the pressure rod 261.

[0058] The pressure rod 261 can swing between a first position and a second position. Before the water bottle 200 is inflated, the pressure rod 261 is in the first position, that is, the pressure rod 261 is at the top dead center position of the upward swing. At this time, the first operating part of the pressure rod 261 and the pressure relief valve 23 are at a first distance, and the second operating part of the pressure rod 261 and the switch valve 25 are at a second distance. The first distance can be set to be smaller than the second distance.

[0059] When the lever 261 is in the second position, i.e., the lever 261 is at the bottom dead center position of the downward swing, the first operating portion of the lever 261 contacts the pressure relief valve 23 to close the pressure relief valve 23, and the second operating portion of the lever 261 contacts the on-off valve 25 to open the on-off valve 25. The on-off valve 25 is normally closed.

[0060] Since the first spacing is smaller than the second spacing before the water bottle 200 is inflated, during the downward swinging of the pressure rod 261, the first operating portion of the pressure rod 261 first presses the pressure relief valve 23 to control the pressure relief valve 23 to be closed, and the second operating portion of the pressure rod 261 then presses the switch valve 25 to control the switch valve 25 to be opened. During the upward swinging of the pressure rod 261, the second operating portion of the pressure rod 261 first separates from the switch valve 25 to close the switch valve 25, and the first operating portion of the pressure rod 261 then separates from the pressure relief valve 23 to open the pressure relief valve 23.

[0061] In this way, by setting a swingable pressure rod 261, the pressure rod 261 can be used to control the pressure relief valve 23 and the switch valve 25 in a linkage manner, ensuring that the pressure relief valve 23 and the switch valve 25 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.

[0062] The driving mechanism 26 may be configured with an elastic support member, which may be disposed between the mounting seat 262 and the pressure rod 261. The elastic support member is used to control the pressure rod 261 to separate from the pressure relief valve 23 when the pressure rod 261 is not pressed. The elastic support member may be a spring or an elastic rod, which is not specifically limited.

[0063] Before the water bottle 200 is inflated, that is, when the pressure rod 261 is not pressed, the elastic support member controls the pressure rod 261 to separate from the pressure relief valve 23. At this time, the pressure rod 261 and the switch valve 25 also remain separated, that is, the switch valve 25 is closed, which makes there is no airflow in the inflation component 2.

[0064] When the water bottle 200 is inflated, the user controls the pressure rod 261 to swing downward. The pressure rod 261 controls the pressure relief valve 23 and the needle valve to operate in sequence, and also compresses the elastic support member so that the elastic support member is in a compressed state.

[0065] When relieving pressure in the water bottle 200, the user can control the pressure rod 261 to swing upward, or the user can release the pressure rod 261, and the elastic support member drives the pressure rod 261 to swing upward. During this process, the pressure rod 261 is separated from the switch valve 25 and the pressure relief valve 23 in turn, thereby controlling the switch valve 25 and the pressure relief valve 23 to operate in turn. After the pressure rod 261 is separated from the pressure relief valve 23, the elastic support member recovers from the compressed state to the initial state. At this time, according to the supporting force provided by the elastic support member to the pressure rod 261, it is ensured that the pressure rod 261 remains separated from the pressure relief valve 23 again.

[0066] In some embodiments, as Figure 3 As shown, the pressure rod 261 includes: a first segment 2611, a second segment 2612 and a third segment 2613; The first segment 2611 is rotatably connected to the mounting seat 262 , and the first segment 2611 is used to press the switch valve 25 ; the second segment 2612 is bent and connected to the first segment 2611 ; the third segment 2613 is bent and connected to the second segment 2612 , and the third segment 2613 is used to press the pressure relief valve 23 .

[0067] It can be understood that the end of the first segment 2611 away from the second segment 2612 is rotatably connected to the mounting seat 262 via a pin shaft, the extension direction of the first segment 2611 is at an obtuse angle to the extension direction of the second segment 2612, the extension direction of the second segment 2612 is at an obtuse angle to the extension direction of the third segment 2613, the first operating part is provided on the side of the third segment 2613 facing the pressure relief valve 23, and the second operating part is provided on the side of the first segment 2611 facing the switch valve 25.

[0068] By configuring the pressure rod 261 into a first segment 2611, a second segment 2612 and a third segment 2613, this design makes it easy to utilize the swing of the pressure rod 261 to control the pressure relief valve 23 and the switch valve 25 to operate in sequence when inflating and depressurizing the water bottle 200, and it is also easy to reduce the swing stroke of the pressure rod 261, thereby realizing a compact design of the entire inflatable component 2 and reducing the volume of the inflatable component 2.

[0069] In some embodiments, as Figure 1 and Figure 3 As shown, the mounting seat 262 includes: a seat body 2621 and a support arm 2622; the seat body 2621 includes a first mounting port 26201 and a second mounting port 26202, the switch valve 25 is passed through the first mounting port 26201 and is connected to the seat body 2621, and the inflation end cover 21 is passed through the second mounting port 26202 and is connected to the seat body 2621; the support arm 2622 is connected to the seat body 2621, and is arranged on the side of the first mounting port 26201 away from the second mounting port 26202, and the pressure rod 261 is rotatably arranged on the support arm 2622.

[0070] It is understood that the support arm 2622 and the base 2621 can be configured to be detachably connected, or the support arm 2622 and the base 2621 can also be an integrated structure. The switch valve 25 can be detachably connected to the base 2621 through a first flange structure, and the inflation end cover 21 can be detachably connected to the base 2621 through a second flange structure.

[0071] The inflation end cover 21 and the switch valve 25 are fixedly installed in an integrated manner based on the base body 2621, ensuring that the inflation end cover 21 and the switch valve 25 are arranged along the horizontal projection direction of the pressure rod 261. This design realizes the integration of the entire inflation component 2. By setting the support arm 2622 on the side of the switch valve 25 away from the inflation component 2, it is convenient to set the pressure rod 261 that can swing up and down based on the support arm 2622, so that the pressure relief valve 23 and the switch valve 25 can move in sequence when inflating and depressurizing the water bottle 200, thereby improving the convenience of the user's inflation operation.

[0072] In some embodiments, as Figure 3As shown, the pressure rod 261 also includes a limit head 2614, which is arranged at one end of the first segment 2611 away from the second segment 2612. The end of the first segment 2611 away from the second segment 2612 is rotatably connected to the mounting seat 262. When the angle of the pressure rod 261 swinging upward or downward relative to the mounting seat 262 reaches a limit angle, the limit head 2614 abuts against the mounting seat 262.

[0073] It can be understood that the end of the first segment 2611 away from the second segment 2612 is rotatably connected to the support arm 2622 of the mounting seat 262 through a pin shaft, and the first segment 2611, the second segment 2612 and the third segment 2613 of the pressure rod 261 are located on one side of the support arm 2622, and the limit head 2614 is located on the other side of the support arm 2622. There is a movable gap between the limit head 2614 and the support arm 2622, and the movable gap is used to limit the swing amplitude of the pressure rod 261 relative to the support arm 2622 within the range of the limited angle.

[0074] Exemplarily, an open groove is provided at the top of the support arm 2622, the pressure rod 261 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 261, the width of the limit head 2614 is greater than the opening width of the open groove.

[0075] When the pressure rod 261 is at the upper dead center position for upward swing, the lower end of the limit head 2614 abuts against the support arm 2622 to prevent the pressure rod 261 from continuing to swing upward relative to the mounting seat 262. At this time, based on the abutment between the lower end of the limit head 2614 and the support arm 2622, the user can be informed that the pressure rod 261 has swung upward to the upper dead center position.

[0076] Correspondingly, when the pressure rod 261 is at the lower dead point position of the downward swing, the upper end of the limit head 2614 abuts against the support arm 2622 to prevent the pressure rod 261 from continuing to swing downward relative to the mounting seat 262. At this time, based on the abutment between the upper end of the limit head 2614 and the support arm 2622, the user can be informed that the pressure rod 261 has swung downward to the lower dead point position. This design can also prevent the user from continuing to press the pressure rod 261 and causing the pressure relief valve 23 and the switch valve 25 to be pressed and damaged.

[0077] In some embodiments, as Figure 9 and Figure 10 As shown, the switch valve 25 includes: A valve chamber 2501, an inlet 2502, an outlet 2503, and a socket 2504. The first end of the valve chamber 2501 is in communication with the inlet 2502, and the second end of the valve chamber 2501 is in communication with the outlet 2503 and the socket 2504, respectively. The outlet 2503 is provided on the side of the socket 2504. The inlet 2502 is used to communicate with the gas cylinder 100, and the outlet 2503 is used to communicate with the inflation tube 22. The elastic member 252 is disposed in the valve chamber 2501 , and a first end of the elastic member 252 abuts against the inlet 2502 . The elastic member 252 may be a spring. The sealing plug 253 is disposed in the valve cavity 2501 . The first end of the sealing plug 253 abuts against the second end of the elastic member 252 . The second end of the sealing plug 253 is used to seal the second end of the valve cavity 2501 . The valve stem 251 is movably inserted into the socket 2504. A sliding seal is formed between the peripheral wall of the valve stem 251 and the inner wall of the socket 2504. The first end of the valve stem 251 is used to receive pressure from the pressure rod 261, and the second end of the valve stem 251 is used to abut the second end of the sealing plug 253. When the valve stem 251 is not pressed, the sealing plug 253 seals the second end of the valve cavity 2501 under the drive of the elastic member 252; when the valve stem 251 is pressed, the valve stem 251 drives the sealing plug 253 to move toward one side of the elastic member 252 to open the second end of the valve cavity 2501.

[0078] It can be understood that, for the switch valve 25, the socket 2504 and the inlet 2502 are arranged relative to each other in the upper and lower directions relative to the valve cavity 2501, and a constriction is formed at the second end of the valve cavity 2501. The valve cavity 2501 is connected to the socket 2504 through the constriction, and the outlet 2503 is arranged on the side wall of the socket 2504 close to the constriction, and is connected to the socket 2504.

[0079] like Figure 9 As shown, when the first end of the valve stem 251 is not pressed by the pressure rod 261, under the elastic force of the elastic member 252, the second end of the sealing plug 253 is inserted into the constriction to seal the second end of the valve cavity 2501. At this time, the second end of the valve stem 251 is separated from the second end of the valve cavity 2501, which makes the second end of the valve stem 251 and the second end of the sealing plug 253 spaced apart; of course, the second end of the valve stem 251 can also contact the second end of the sealing plug 253, but since the sealing plug 253 is always subjected to the elastic force of the elastic member 252, the valve stem 251 will not change the sealing effect of the sealing plug 253 on the second end of the valve cavity 2501.

[0080] like Figure 10As shown, when the first end of the valve stem 251 is pressed by the pressure rod 261, the valve stem 251 will move toward the sealing plug 253 until the second end of the valve stem 251 contacts the second end of the sealing plug 253 and applies pressure to the sealing plug 253. When the pressure of the valve stem 251 on the sealing plug 253 is greater than the elastic force of the elastic member 252 on the sealing plug 253, the sealing plug 253 will move toward one side of the elastic member 252 until there is a gap between the sealing plug 253 and the necking, so as to release the seal on the second end of the valve cavity 2501. At this time, the gas will enter the valve cavity 2501 from the inlet 2502 and then be discharged from the outlet 2503.

[0081] In some embodiments, as Figure 2 、 Figure 4 and Figure 8 As shown, the sparkling water machine also includes: a safety valve 24, which is arranged on the inflation end cover 21 and is connected to the inflation interface 211; during the inflation process of the water bottle 200, the safety valve 24 is used to open the pressure relief when the air pressure in the water bottle 200 is greater than the pressure relief threshold.

[0082] It is understandable that when the water bottle 200 is inflated, most of the gas, such as carbon dioxide 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, the safety valve 24 opens to relieve pressure to ensure inflation safety.

[0083] In practical applications, the safety valve 24 can be a safety valve with a fixed pressure relief threshold or a safety valve with an adjustable pressure relief threshold, such as a spring-loaded safety valve. When the safety valve 24 is a safety valve with an adjustable pressure relief threshold, the concentration of the prepared bubble water can be flexibly adjusted by adjusting the pressure relief threshold of the safety valve 24 according to actual needs.

[0084] In some embodiments, as Figure 2 and Figure 8 As shown, 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 inflation interface 211, wherein the safety valve chamber 2401, the communication port 2402, the exhaust port 2403 and the regulating port 2404 are all provided on the inflation end cover 21; 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.

[0085] It can be understood that 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.

[0086] 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.

[0087] In some embodiments, as Figure 8 As shown, the adjustable part 241 includes: a valve head 2411 and a driving part 2412; the valve head 2411 is movably arranged in the adjustment port 2404 and abuts against the elastic element 243; the driving part 2412 is connected to the valve head 2411, and the driving part 2412 is used to drive the valve head 2411 to move so as to adjust the position of the valve head 2411 relative to the adjustment port 2404.

[0088] 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.

[0089] 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 .

[0090] For example, Figure 8As 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.

[0091] 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.

[0092] In some embodiments, as Figure 8 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.

[0093] 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.

[0094] 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.

[0095] 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 .

[0096] In some embodiments, as Figure 8 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.

[0097] 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.

[0098] In some embodiments, as Figure 2 、 Figure 4 and Figure 7 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.

[0099] 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 261 of the driving mechanism 26 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 will press 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.

[0100] 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 261 of the control driving mechanism 26 is swung 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 may 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.

[0101] In some embodiments, as Figure 7 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.

[0102] In some embodiments, as Figure 7 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 .

[0103] 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.

[0104] 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.

[0105] 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.

[0106] 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 .

[0107] 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.

[0108] 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.

[0109] 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.

[0110] In some embodiments, as Figure 2 and Figure 11 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 guide slope 21131, a hollow opening 21132, and a limit portion 21133; the guide 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 guide slope 21131 is used to slide with the protrusion of the water bottle 200 to guide the bottle opening of the water bottle 200 to rotate into the cap structure 2111; the hollow opening 21132 It penetrates the side wall of the cap structure 2111 and is arranged opposite to the guiding inclined surface 21131; the limiting portion 21133 is arranged in the hollow opening 21132, and is spaced apart from the guiding inclined surface 21131 along the circumference of the cap structure 2111 and the end of the cap top close to the cap structure 2111; wherein, 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] In the second aspect, Figure 4 As shown, an embodiment of the present invention further provides a sparkling water machine, comprising: Inflatable assembly 2 as described above; The gas supply component 1 is used to be sealed and connected with the gas cylinder 100, and the gas supply component 1 is connected with the switch valve 25, for example, the gas supply component 1 is connected with the switch valve 25 through the first transfer tube 3; wherein, the gas supply component 1 is used to control the gas cylinder 100 to supply gas to the inflation component 2.

[0115] It can be understood that the gas supply component 1 is used to control the opening of the one-way valve at the bottle mouth of the gas cylinder 100 so that the gas cylinder 100 starts to supply gas. The gas supply component 1 can also be used to control the gas supply pressure of the gas cylinder 100.

[0116] The bubble water machine shown in the present invention is configured with an air supply component 1 and an inflation component 2. This design integrates the bubble water machine into an air supply component 1 and an inflation component 2 that are separate from each other, simplifies the design structure of the bubble water machine, reduces the size of the equipment, reduces the equipment cost, enhances the versatility of the bubble water machine, can adapt to different installation conditions for the flexible installation layout of the bubble water machine, and improves the convenience of maintenance of the bubble water machine.

[0117] Since the bubble water machine includes an inflation component 2, and the specific structure of the inflation component 2 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.

[0118] In some embodiments, as Figure 4 、 Figure 12 and Figure 13 As shown, the air supply assembly 1 includes: an air supply seat 11, a ejector pin 13 and a pressure reducing valve 12; The gas supply seat 11 has a gas supply interface 111, which is used to be sealed and connected to the gas cylinder 100; the ejector pin 13 is arranged in the gas supply interface 111, which is used to trigger the one-way valve in the gas cylinder 100 to open; the pressure reducing valve 12 is arranged on the gas supply seat 11, and the pressure reducing valve 12 is connected to the gas supply interface 111 through the ejector pin 13, and the pressure reducing valve 12 is connected to the switch valve 25.

[0119] It is understandable that 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 and a sealing ring; The interface groove is formed on the bottom wall of the gas supply seat 11, the bottom of the interface groove is connected to the needle valve, and the groove wall of the interface groove is threadedly connected to the bottle mouth of the gas cylinder 100. For example, the groove wall of the interface groove is provided with an internal thread, and the interface groove 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 is provided at the bottom of the interface groove, and the sealing ring is used to seal the port of the bottle mouth.

[0120] The ejector pin 13 is provided with an air hole along its axial direction. The ejector pin 13 can be arranged at the bottom of the interface groove. For example, the ejector pin 13 and the bottom of the interface groove are threadedly connected. The first end of the ejector pin 13 extends into the interface groove to realize the communication between the ejector pin 13 and the gas supply interface 111. The second end of the ejector pin 13 can be connected with the pressure reducing valve 12 through the air path structure; when the gas supply interface 111 is connected to the bottle mouth of the gas cylinder 100, the ejector pin 13 abuts against the one-way valve arranged at the bottle mouth of the gas cylinder 100, so that the one-way valve is opened, so that the gas in the gas cylinder 100 can flow to the ejector pin 13 through the one-way valve, and then flow to the inflation component 2 through the pressure reducing valve 12.

[0121] The pressure reducing valve 12 can be a spring-loaded pressure reducing valve or a pilot-operated pressure reducing valve, and there is no specific limitation on this. The pressure reducing valve 12 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 sparkling water machine, reduce the impact of the high-pressure airflow on the components, and improve the safety of the equipment.

[0122] In some embodiments, as Figure 12 and Figure 13 As shown, the pressure reducing valve 12 includes: The pressure reducing valve chamber 1201 and the air inlet channel 1202 and the air outlet 1203 communicated with the pressure reducing valve chamber 1201 . The air inlet channel 1202 communicates with the ejector pin 13 . A throttle port 12021 is provided in the air inlet channel 1202 . The elastic member 121 is disposed in the pressure reducing valve chamber 1201; The valve core assembly 122 includes a core body 1221 and a throttling element 1222. The core body 1221 is movably arranged in the pressure reducing valve chamber 1201. The core body 1221 is in contact with the inner wall of the pressure reducing valve chamber 1201 through the elastic component 121. The throttling element 1222 is passed through the throttling port 12021 and can move relative to the throttling port 12021 following the core body 1221. The throttling element 1222 and the throttling port 12021 cooperate to control the flow of gas entering the pressure reducing valve chamber 1201.

[0123] It can be understood that the air inlet channel 1202 and the pressure reducing valve chamber 1201 are both formed in the air supply seat 11, the air inlet channel 1202 is arranged at the first end of the pressure reducing valve chamber 1201, the core body 1221 is arranged close to the first end of the pressure reducing valve chamber 1201, the elastic member 121 is abutted between the core body 1221 and the second end of the pressure reducing valve chamber 1201, and the air outlet 1203 is arranged on the side of the pressure reducing valve chamber 1201; wherein, an exhaust chamber for connecting the air inlet channel 1202 and the air outlet 1203 is formed between the core body 1221 and the first end of the pressure reducing valve chamber 1201, and a sliding seal is realized between the peripheral wall of the core body 1221 and the inner wall of the pressure reducing valve chamber 1201, for example, the core body 1221 is in sliding contact with the inner wall of the pressure reducing valve chamber 1201 through a Y-type seal to ensure the sealing of the exhaust chamber.

[0124] For the valve core assembly 122, the part of the throttling element 1222 extending into the pressure reducing valve chamber 1201 can be directly connected to the core body 1221. For example, the part of the throttling element 1222 extending into the pressure reducing valve chamber 1201 is threadedly connected to the middle part of the core body 1221. The part of the throttling element 1222 extending into the pressure reducing valve chamber 1201 can also be connected through other transition structures to enable the throttling element 1222 to follow the core body 1221 to move relative to the throttling port 12021. Since the gap between the inner wall of the throttle port 12021 and the peripheral wall of the throttle element 1222 is small at the throttle port 12021, the gas output from the gas cylinder 100 has a large pressure loss when passing through the gap between the throttle port 12021 and the throttle element 1222. When the high-pressure gas passes through the throttle port 12021 and reaches the pressure reducing valve chamber 1201, it will be converted into low-pressure gas and then discharged from the gas outlet 1203, that is, the pressure reducing valve 12 realizes the pressure reducing output of the gas.

[0125] The throttling element 1222 has a changing shape along its axial direction, so that when the throttling element 1222 moves relative to the throttling port 12021, the size of the gap between the throttling element 1222 and the throttling port 12021 changes, thereby enabling the flow of gas entering the pressure reducing valve chamber 1201 to be controlled based on the mutual cooperation between the throttling element 1222 and the throttling port 12021.

[0126] Considering that the pressure reducing valve 12 controls the pressure reduction of the airflow output by the gas cylinder 100, it can be set that when the valve core assembly 122 moves toward one side of the elastic member 121, the gap between the throttling element 1222 and the throttling port 12021 gradually decreases.

[0127] like Figure 12 and Figure 13 As shown, when the gas supply interface 111 is connected to the bottle mouth of the gas cylinder 100, the ejector pin 13 can trigger the gas cylinder 100 to open, and the gas output from the gas cylinder 100 enters the exhaust chamber corresponding to the pressure reducing valve chamber 1201 through the gap between the throttle port 12021 and the throttle element 1222. When the gas pressure is relatively high, the core 1221 will move toward one side of the elastic member 121 under the action of the gas pressure in the exhaust chamber, that is, the core 1221 will move to a position away from the first end of the pressure reducing valve chamber 1201. During this process, the gap between the throttling element 1222 and the throttle port 12021 gradually decreases, and the pressure reducing effect of the pressure reducing valve 12 on the gas gradually increases, so that the gas pressure in the exhaust chamber decreases until the elastic force of the elastic component 121 on the core 1221 and the pressure of the gas pressure in the exhaust chamber on the core 1221 reach a balance, and the core 1221 no longer drives the throttling element 1222 to move relative to the throttle port 12021, ensuring that the pressure reducing valve 12 can stably achieve gas pressure reduction output with corresponding pressure reducing parameters in this state.

[0128] 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 121, the core 1221 will drive the throttling element 1222 to move toward the side away from the elastic member 121 until it stops moving when a new force balance is reached.

[0129] In actual application, when the air outlet 1203 is blocked or other faults occur, the air pressure in the exhaust chamber corresponding to the pressure reducing valve chamber 1201 will increase instantly, and the core 1221 will drive the throttling element 1222 to move toward the side of the elastic component 121 until the gap between the throttling element 1222 and the throttling port 12021 is reduced to zero, that is, the throttling element 1222 will block the throttling port 12021 to ensure that low pressure is maintained in the exhaust chamber, so that the pressure applied to the core 1221 by the exhaust chamber is always equal to the elastic force of the elastic component 121, thereby preventing the continuous output of high-pressure airflow and avoiding damage to the outlet 2503 device.

[0130] In some embodiments, as Figure 12 As shown, the first end of the core 1221 abuts against the elastic member 121 , and the second end of the core 1221 is connected to the throttling element 1222 .

[0131] For example, a threaded hole is provided in the middle of the second end of the core body 1221 , and a threaded joint is formed on one end of the throttling element 1222 facing the core body 1221 , and the threaded joint is threadedly connected to the threaded hole.

[0132] For example, a peripheral wall of the throttling element 1222 at one end facing the core body 1221 is further provided with an annular protrusion, which is arranged close to the threaded joint and contacts the core body 1221 .

[0133] When the gas pressure is too high and causes the throttling element 1222 to block the throttling port 12021, the annular protrusion will abut against the core body 1221 to prevent the connection between the threaded joint on the throttling element 1222 and the core body 1221 from failing, thereby protecting the entire throttling element 1222.

[0134] In some embodiments, as Figure 12 and Figure 13 As shown, the throttling element 1222 includes: a connecting rod 12221 and a conical head 12222; The first end of the connecting rod 12221 is connected to the second end of the core body 1221 , and the conical head 12222 has a conical head end disposed toward the throttle port 12021 , and the conical head end is connected to the second end of the connecting rod 12221 .

[0135] It can be understood that the diameter of the connecting rod 12221 is smaller than the diameter of the throttle port 12021, and the diameter of the connecting rod 12221 is equal to the diameter of the end of the cone head close to the throttle port 12021. The diameter of the cone head end gradually increases from the end of the cone head end close to the throttle port 12021 to the end of the cone head end away from the throttle port 12021.

[0136] In this way, in the process of the valve core assembly 122 moving toward one side of the elastic member 121, the connecting rod 12221 drives the conical head 12222 to move toward the throttle port 12021, and the end of the conical head end close to the throttle port 12021 (the end with the smaller diameter of the conical head end) is gradually inserted into the throttle port 12021. Since the conical head end is based on the inclined surface and cooperates with the inner wall of the throttle port 12021, in the process of the conical head end gradually being inserted into the throttle port 12021, the gap between the throttle element 1222 and the throttle port 12021 gradually decreases.

[0137] In some embodiments, an elastic sealing ring is provided on the side of the throttle port 12021 away from the pressure reducing valve chamber 1201. When the throttle element 1222 blocks the throttle port 12021, the elastic sealing ring is used to seal with the peripheral wall of the conical head 12222 to ensure the sealing between the throttle port 12021 and the throttle element 1222.

[0138] In some embodiments, as Figure 13 As shown, the valve core assembly 122 further includes: a core seat 1223 and an elastic compression member 1224; the core seat 1223 is movably disposed on the core body 1221, and the throttling element 1222 is connected to the core seat 1223, and the throttling element 1222 contacts the core body 1221 at one end thereof facing the core body 1221; the elastic compression member 1224 is disposed in the pressure reducing valve cavity 1201 and abuts between the inner wall of the pressure reducing valve cavity 1201 and the core seat 1223; In the process of the core body 1221 moving toward one side of the elastic component 121, the elastic compression member 1224 drives the core seat 1223 to drive the throttling element 1222 to move toward the core body 1221; in the process of the core body 1221 moving toward the side away from the elastic component 121, the core body 1221 and the throttling element 1222 abut against each other to drive the throttling element 1222 to move.

[0139] It can be understood that the throttle port 12021 is arranged at the first end of the pressure reducing valve chamber 1201, the core body 1221 is arranged close to the first end of the pressure reducing valve chamber 1201, the elastic member 121 is abutted between the core body 1221 and the second end of the pressure reducing valve chamber 1201, and the air outlet 1203 is connected to the pressure reducing valve chamber 1201 through a gas channel; wherein, an exhaust chamber for connecting the air inlet channel 1202 and the air outlet 1203 is formed between the core body 1221 and the first end of the pressure reducing valve chamber 1201.

[0140] A receiving groove is provided on the side of the core body 1221 away from the elastic component 121, and the groove opening of the receiving groove is set toward the throttle port 12021. The core seat 1223 is movably set in the receiving groove, for example, the receiving groove is set horizontally, and the peripheral wall of the core seat 1223 slides with the groove wall of the receiving groove.

[0141] Core seat 1223 is formed with a through hole, into which the central portion of throttling element 1222 is mounted. The end of core seat 1223 facing away from elastic compression member 1224 is spaced from the bottom of the accommodating groove, while the end of throttling element 1222 facing core body 1221 contacts a positioning groove provided at the bottom of the accommodating groove. Elastic compression member 1224 can be a compression spring, which is sleeved around the outside of throttling element 1222 and abuts between the inner wall of the first end of pressure reducing valve chamber 1201 and core seat 1223.

[0142] 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 1201 through the gap between the throttle port 12021 and the throttling element 1222. When the pressure of the gas is relatively high, the core 1221 will move toward one side of the elastic member 121 under the action of the pressure of the gas in the exhaust chamber. At this time, the core 1221 has a tendency to separate from the throttling element 1222. Since the elastic compression member 1224 abuts between the inner wall of the pressure reducing valve chamber 1201 and the core seat 1223, the elastic compression member 1224 will drive the core seat 1223 to drive the throttling element 1222 toward the core 1221, ensuring that the throttling element 1222 moves toward One end of the core 1221 remains in contact with the core 1221 during the movement, that is, the throttling element 1222 follows the core 1221 to move toward one side of the elastic component 121. During this process, the gap between the throttling element 1222 and the throttle port 12021 gradually decreases, and the pressure reducing effect of the pressure reducing valve 12 on the gas gradually increases, so that the air pressure in the exhaust chamber decreases until the elastic force of the elastic component 121 on the core 1221 and the pressure of the air pressure in the exhaust chamber on the core 1221 reach a balance, and the throttling element 1222 no longer moves relative to the throttle port 12021, ensuring that the pressure reducing valve 12 in this state can stably achieve gas pressure reduction output with corresponding pressure reducing parameters.

[0143] 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 121, the core 1221 will drive the throttling element 1222 to move toward the side away from the elastic member 121 until it stops moving when a new force balance is reached.

[0144] Based on the above design structure of the valve core assembly 122, the pressure reducing valve 12 has the following protection mechanism during operation: when the air outlet 1203 is blocked or closed, the air pressure in the exhaust chamber corresponding to the pressure reducing valve chamber 1201 will increase instantly, thereby pushing the core body 1221 to move toward one side of the elastic component 121, and the throttling element 1222 will accordingly follow the core body 1221 under the drive of the elastic compression member 1224 until the throttling element 1222 blocks the throttling port 12021. Compared with directly rigidly connecting the core body 1221 and the throttling element 1222, this design can not only protect the throttling element 1222 and prevent the instantaneous movement of the throttling element 1222 driven by the core body 1221 from causing damage to the throttling element 1222 and the throttling port 12021, but also use the throttling element 1222 to block the throttling port 12021 to prevent the continuous output of high-pressure airflow and damage to the outlet 2503 device.

[0145] In some embodiments, as Figure 13As shown, the air supply assembly 1 also includes a safety protection valve 14, which is arranged on the air supply seat 11 and is connected to the pressure reducing valve chamber 1201; when the seal between the throttling element 1222 and the throttle port 12021 fails, the safety protection valve 14 is used to provide pressure relief protection for the pressure reducing valve 12.

[0146] It can be understood that the safety protection valve 14 includes a pressure relief chamber, a safety valve spring and a safety valve core. The pressure relief chamber has an air inlet end and a pressure relief end. The safety valve spring and the safety valve core are both arranged in the pressure relief chamber. 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 chamber 1201 through an air channel arranged in the air supply seat 11, and the pressure relief end is used to connect the pressure relief chamber of the safety protection valve 14 with the atmospheric environment.

[0147] If the seal between throttle element 1222 and throttle port 12021 fails, even if throttle element 1222 closes throttle port 12021, high-pressure gas will slowly leak into pressure-reducing valve chamber 1201 of pressure-reducing valve 12 along the gap between throttle element 1222 and throttle port 12021, and then be discharged from gas outlet 1203 of pressure-reducing valve 12, causing the pressure-reducing function of pressure-reducing valve 12 to fail. The high-pressure gas discharged through pressure-reducing valve 12 may cause significant damage to the outlet 2503. However, by providing a safety valve 14 in this embodiment, when the air pressure in pressure-reducing valve chamber 1201 exceeds the pressure relief valve 23 value (e.g., 1 MPa) of safety valve 14, pressure relief is provided through safety valve 14. This ensures the safety of subsequent use of outlet 2503 of pressure-reducing valve 12 when the seal between throttle element 1222 and throttle port 12021 fails.

[0148] In a third aspect, an embodiment of 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.

[0149] It can be understood 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, water purifier or coffee machine.

[0150] Since the household appliance includes a bubble water machine, the specific structure of the bubble water machine refers to the above embodiment, and the household appliance 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.

[0151] Finally, it should be noted that the above embodiments are intended to illustrate the present invention only and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications, or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention and are intended to be encompassed by the claims of the present invention.
