Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a locking component and a sparkling water machine. Background Technology

[0002] With people's pursuit of a healthy lifestyle, sparkling water has become increasingly popular as a healthy beverage. Sparkling water makers, as devices that allow consumers to produce carbonated drinks at home, make it convenient for them to create their own favorite sparkling water. The principle of a sparkling water maker is to pressurize carbon dioxide from the gas supply unit into a bottle containing water, turning the water into sparkling water.

[0003] Traditional sparkling water machines often use screw-on snap-fit ​​connections or manual alignment of the nozzle to connect the water bottle and the nozzle. This is cumbersome and time-consuming, and the height of the operating table often limits the user's ability to bend over to align the nozzle, making it inconvenient and negatively impacting the user experience. To address this, some sparkling water machines on the market have incorporated a transmission mechanism. This mechanism is connected to both the water bottle and the nozzle. When the water bottle is aligned with the transmission mechanism and installed on the sparkling water machine, the nozzle automatically aligns and connects to the bottle's air inlet. This improves the visibility of the device and eliminates the need for the user to bend over to observe the nozzle's position. However, this new design also results in a lower level of security for the nozzle compared to traditional fixed installations. There is a risk of leakage, loosening, and potential accidents due to excessive gas pressure during filling. Utility Model Content

[0004] Therefore, it is necessary to provide a locking component and a sparkling water machine to address the problem that the installation of the movable air inlet of the existing sparkling water machine is not secure enough, and that excessive gas pressure during injection may lead to air leakage, loosening, and the risk of accidents.

[0005] A locking assembly includes: a mounting base having an installation space for mounting an air nozzle of a sparkling water machine; a limiting block movably disposed on the mounting base and having at least a locked position and a released position, wherein when the limiting block is in the locked position, the limiting block is configured to restrict and lock the air nozzle, and when the limiting block is in the released position, the limiting block is configured to move away from the installation space and release the air nozzle; and an operating member movably disposed on the mounting base, the operating member being drively connected to the limiting block, and the operating member being capable of driving the limiting block to move from the locked position to the released position under the action of an external force.

[0006] This application discloses a locking assembly. A limiting block and an operating element are provided on the mounting base. The limiting block can form a locking relationship with an air injection nozzle disposed in the installation space, thus ensuring the air injection nozzle is more securely mounted in the mounting base and allowing for safe air injection operations. This significantly reduces the risk of leakage, loosening, and accidents caused by gas pressure surges. After air injection is completed, the user can operate the operating element to move the limiting block to the release position. The limiting block moves away from the installation space and separates from the air injection nozzle, releasing the locking relationship and allowing the air injection nozzle to be released and reset.

[0007] In one embodiment, the limiting block has a first locking portion configured to engage with a second locking portion of the air nozzle to lock and restrict the air nozzle. The locking method offers advantages such as simple structure, ease of installation, disassembly, and maintenance. The engagement of the first and second locking portions provides a stable and secure connection, ensuring that the nozzle will not loosen or shift under slight vibration or other vibration conditions.

[0008] In one embodiment, the first snap-fit ​​portion has a chamfer or bevel on the side near the mounting space. During the snap-fit ​​process of the second snap-fit ​​portion of the air nozzle approaching the first snap-fit ​​portion, the chamfer or bevel can cause either the second or first snap-fit ​​portion to deform under pressure, thereby reducing the difficulty of the snap-fit ​​operation and facilitating installation.

[0009] In one embodiment, a first spring is further included, with its two ends abutting against the limiting block and the mounting base, respectively. When the limiting block moves from the locked position to the released position, the first spring deforms and accumulates elastic force to drive the limiting block back from the released position to the locked position. By providing the first spring, when the external force applied by the user to the operating component disappears, the first spring will quickly and elastically recover, driving the limiting block and the operating component back to their original positions for the next use, simplifying user operation. Furthermore, the first spring also acts as a limiter on the limiting block, preventing the limiting block from disengaging from the locked position and causing the locking function to fail when the second locking part of the air nozzle is pressed against the first locking part on the limiting block.

[0010] In one embodiment, a second spring is also included, with its two ends abutting against the operating member and the mounting base, respectively. When the limiting block is in the released position, the second spring deforms. By providing the second spring, when the external force applied by the user to the operating member disappears, the second spring will quickly and elastically return to its original position, driving the operating member to reset for the next use, thus simplifying user operation.

[0011] In one embodiment, the housing assembly is formed with a positioning plate, and the end of the second spring away from the operating member abuts against the positioning plate.

[0012] In one embodiment, the operating member is provided with a positioning groove, the second spring is at least partially located in the positioning groove, and the end of the second spring away from the positioning plate abuts against the bottom wall of the positioning groove.

[0013] In one embodiment, a trigger is further included, which is rotatably mounted on the mounting base. When the trigger rotates under the action of an external force, it can actuate the operating element to control the operation of the operating element.

[0014] In one embodiment, the mounting base is provided with a first groove along a first direction, the limiting block is slidably disposed in the first groove, and the top wall of the limiting block is provided with a second groove along a second direction, the first direction intersecting the second direction. The operating member has a first abutment portion formed at one end near the limiting block, at least a portion of the first abutment portion extending into the second groove. The first abutment portion is configured to drive the operating member to slide along the first groove when sliding under external force, and has at least the locked position and the released position. When the user operates the operating member to move along the second direction, the first abutment portion of the operating member will slide along the second groove. Under the cooperation of the first abutment portion and the second groove, and the constraint of the first groove, the limiting block can be driven to move along the first direction to the release position to unlock the air nozzle. By adopting the above method, the excessive clearance space caused by the operating member and the limiting block moving in the same direction can be avoided, which is beneficial to improving the structural compactness of the device.

[0015] In one embodiment, the first spring is disposed in the first groove, with the end of the first spring away from the limiting block abutting against the inner wall of the first groove. This structure ensures a more stable placement of the first spring.

[0016] In one embodiment, the inner sidewall of the second slide groove is provided with a first inclined surface extending towards the first abutting portion. The first abutting portion is provided with a second inclined surface that abuts against the first inclined surface. When the first abutting portion slides along the second slide groove, the engagement of the first and second inclined surfaces causes the limiting block to move away from or towards the mounting space. By adopting the above structure, the first and second inclined surfaces remain tightly engaged under the action of the first spring. When the first abutting portion moves along the front-back direction of the second slide groove, the driving force that drives the first abutting portion to move in the second direction can be partially decomposed into a driving force that drives the limiting block to move in the first direction, thereby achieving a direction change.

[0017] In one embodiment, the first inclined surface extends toward the first abutment and gradually slopes away from the mounting space. When the user applies an external force to move the first abutment toward the limiting block, the first inclined surface slides relative to the second inclined surface, causing the limiting block to move away from the mounting space to the release position.

[0018] In one embodiment, a first limiting rib is provided at the top of the inner wall of the first slide groove. The first limiting rib is arranged along the length direction of the first slide groove, and a limiting protrusion is formed on the side wall of the limiting block. The top wall of the limiting protrusion is slidably connected to the first limiting rib. By adopting the above structure, it can be ensured that the limiting block can be securely set in the first slide groove, preventing the limiting block from disengaging from the top opening of the first slide groove, thereby enabling a more stable locking function for the air injection nozzle.

[0019] In one embodiment, the mounting base protrusion has a third engaging portion, which has a second engaging groove. The first abutment portion is slidably engaged in the second engaging groove. The third engaging portion provides a positioning function. When the first abutment portion is engaged in the second engaging groove, it slides along the sidewall of the second engaging groove, while its top wall abuts against the third engaging portion. This allows the first abutment portion to slide more directionally and prevents it from detaching upwards during sliding.

[0020] In one embodiment, the first direction is perpendicular to the second direction.

[0021] In one embodiment, the mounting base is provided with a third sliding groove. The top of the inner walls on both sides of the third sliding groove are respectively provided with second limiting ribs. The second limiting ribs are arranged along the length direction of the third sliding groove. The bottom of the operating member abuts against the top wall of the third sliding groove. Two latches are formed at the bottom of the operating member, and each latch extends into the third sliding groove and engages with one of the two second limiting ribs. By adopting the above structure, the bottom of the operating member abuts against the top wall of the third sliding groove, thereby facilitating the movement of the first abutting part above the limiting block. Simultaneously, the two latches formed at the bottom of the operating member extend into the third sliding groove and engage with the second limiting ribs. The latches and the second limiting ribs cooperate to limit the movement of the operating member, preventing it from deviating when sliding along the length direction of the third sliding groove and making it less prone to loosening.

[0022] In one embodiment, the operating member has a second abutment portion, and a third inclined surface is formed at the end of the second abutment portion near the mounting space. The third inclined surface extends in the direction near the mounting space and is configured to slide against the bottom wall of the air nozzle to drive the air nozzle upward. With this structure, when the user operates the operating member to move towards the limiting block, the third inclined surface on the second abutment portion will abut against and slide against the bottom wall of the air nozzle. This allows the operating member to drive the limiting block from the locked position to the released position, releasing the air nozzle. Simultaneously, the second abutment portion can also raise the air nozzle upward, making the separation of the air nozzle from the water bottle faster and smoother.

[0023] In one embodiment, the third inclined plane extends toward the mounting space and slopes downward.

[0024] In one embodiment, there are two limiting blocks, each disposed on opposite sides of the installation space. The operating component includes an operating lever and two first abutment portions. One end of each of the two first abutment portions is connected to the operating lever, and the other end of each first abutment portion is connected to one of the two limiting blocks respectively. By providing two limiting blocks, they can be engaged with the second locking portions on both sides of the gas nozzle, thereby making the gas nozzle more stable under force and more secure in installation, greatly reducing the risk of leakage, loosening, and accidents caused by gas pressure impact. Furthermore, the operating component includes two first abutment portions, which can simultaneously drive the two limiting blocks, thereby improving the unlocking operation speed.

[0025] In one embodiment, the two limiting blocks are arranged symmetrically.

[0026] In one embodiment, the two first abutment portions are arranged symmetrically.

[0027] In one embodiment, a portion of the operating lever away from the first abutment abuts against the trigger.

[0028] In one embodiment, the mounting base has a mounting cavity, within which the limiting block and the operating component are disposed. By providing a mounting cavity on the mounting base for mounting the limiting block and the operating component, protection and dust prevention are achieved, and the sparkling water machine becomes more aesthetically pleasing.

[0029] The second aspect of this application discloses a sparkling water machine.

[0030] A sparkling water machine includes: a housing assembly with a recessed accommodating space on its outer side wall, the accommodating space communicating with a mounting space; the aforementioned locking assembly, the mounting base being disposed on the housing assembly; an injection nozzle disposed in the mounting space; a water bottle detachably disposed in the accommodating space, the air inlet end of the water bottle being detachably connected to the injection nozzle; and an air supply device communicating with the injection nozzle, the air supply device introducing gas into the water bottle through the injection nozzle. The sparkling water machine disclosed in the second aspect of this application, by employing the locking assembly of any one of the aforementioned methods, has a mounting base equipped with a limiting block and an operating component. The limiting block can form a locking relationship with the injection nozzle disposed in the mounting space, thereby ensuring the injection nozzle is more securely disposed in the mounting base and safely performing the injection operation, greatly reducing the risk of leakage, loosening, and accidents caused by gas pressure impact. Once the air injection is complete, the user can move the limit block to the release position by operating the control element. The limit block moves away from the installation space and separates from the air injection nozzle, thus releasing the locking relationship and allowing the air injection nozzle to be released and reset.

[0031] In one embodiment, the air nozzle is retractable relative to the accommodating space and has at least a first position and a second position. When the air nozzle is in the first position, it is separated from the air inlet of the water bottle. When the air nozzle is in the second position, it is connected to the air inlet of the water bottle and can be locked by the limiting block. The system also includes a rotating pressure rod, which is rotatably connected to the mounting base via a rotating shaft. The two ends of the rotating pressure rod form a third abutment and a fourth abutment, respectively. The third abutment extends into the accommodating space, and the fourth abutment is disposed opposite to the air nozzle. The water bottle is detachably connected to the third abutment. The water bottle can drive the rotating pressure rod to rotate under the action of an external force, so that the fourth abutment abuts against the air nozzle and drives the air nozzle to move from the first position to the second position. By setting a rotating pressure rod that is connected to the water bottle and the air nozzle respectively, when the user assembles the water bottle to make sparkling water, the water bottle will be connected to the third abutment part and driven to rotate under the action of external force. As a result, the fourth abutment part will be driven to rotate and push the air nozzle from the first position to the second position to connect with the air inlet end of the water bottle, so that the air supply device can deliver carbon dioxide gas through the air nozzle.

[0032] In one embodiment, the air nozzle has a second engaging portion, and the first engaging portion of the limiting block can engage with the second engaging portion to restrict and lock the air nozzle. Specifically, one of the first engaging portion and the second engaging portion is a protrusion, and the other is a first slot. When the air nozzle is in the second position and the limiting block is in the locked position, the protrusion can engage with the first slot, so that the limiting block restricts and locks the air nozzle.

[0057] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0058] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0059] The locking components of some embodiments of the present invention are described below with reference to the accompanying drawings.

[0060] like Figures 1 to 8 As shown, this embodiment discloses a locking assembly, including: a mounting base 1, the mounting base 1 having an installation space 101 for installing the air nozzle of a sparkling water machine; a limiting block 2, the limiting block 2 being movably disposed on the mounting base 1 and having at least a locked position and a released position, the limiting block 2 being configured to restrict and lock the air nozzle when in the locked position, and the limiting block 2 being configured to move away from the installation space 101 and release the air nozzle when in the released position; and an operating member 3, the operating member 3 being movably disposed on the mounting base 1, the operating member 3 being drively connected to the limiting block 2, and the operating member 3 being able to drive the limiting block 2 to move from the locked position to the released position under the action of an external force.

[0061] This application discloses a locking assembly. A limiting block 2 and an operating element 3 are provided on the mounting base 1. The limiting block 2 can form a locking relationship with the air injection nozzle disposed in the mounting space 101, thus ensuring the air injection nozzle is more securely mounted in the mounting base 1 and allowing for safe air injection operations. This significantly reduces the risk of leakage, loosening, and accidents caused by gas pressure impacts. After air injection is completed, the user can operate the operating element 3 to move the limiting block 2 to the release position. The limiting block 2 moves away from the mounting space 101 and separates from the air injection nozzle, releasing the locking relationship and allowing the air injection nozzle to be released and reset.

[0062] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the limiting block 2 has a first locking portion 21, which is configured to engage with the second locking portion of the air nozzle to lock and restrict the air nozzle. The locking method has the advantages of simple structure, easy installation, disassembly, and maintenance. The engagement of the first locking portion 21 and the second locking portion provides a stable and secure connection, ensuring that it will not loosen or shift under slight vibration or other vibration environments.

[0063] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first snap-fit ​​portion 21 has a chamfer or bevel on the side near the installation space 101. During the snap-fit ​​process of the second snap-fit ​​portion of the air nozzle approaching the first snap-fit ​​portion 21, the second snap-fit ​​portion or the first snap-fit ​​portion 21 can be squeezed and deformed under the action of the chamfer or bevel, thereby reducing the difficulty of the snap-fit ​​operation and making the installation smooth.

[0064] like Figure 1 , Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further includes a first spring 4. The two ends of the first spring 4 abut against the limiting block 2 and the mounting base 1, respectively. When the limiting block 2 moves from the locked position to the released position, the first spring 4 deforms and accumulates elastic force to drive the limiting block 2 back to the locked position from the released position. With the first spring 4, when the external force applied by the user to the operating member 3 disappears, the first spring 4 will quickly and elastically recover and drive the limiting block 2 and the operating member 3 back to their original positions to meet the needs of the next round of use, simplifying the user's operation. Furthermore, the first spring 4 also acts as a limiter on the limiting block 2, preventing the limiting block 2 from disengaging from the locked position and causing the locking function to fail when the second locking part of the air nozzle is pressed against the first locking part 21 on the limiting block 2.

[0065] like Figure 1 and Figure 3As shown, in addition to the features of the above embodiments, this embodiment further includes a second spring 5. The two ends of the second spring 5 abut against the operating member 3 and the mounting base 1, respectively. When the limiting block 2 is in the released position, the second spring 5 deforms. With the second spring 5, when the external force applied by the user to the operating member 3 disappears, the second spring 5 will quickly and elastically recover, driving the operating member 3 to reset for the next round of use, thus simplifying user operation.

[0066] like Figure 1 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 200 is formed with a positioning plate 11, and the end of the second spring 5 away from the operating member 3 abuts against the positioning plate 11.

[0067] like Figure 6 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the operating member 3 is provided with a positioning groove 301, the second spring 5 is at least partially located in the positioning groove 301, and the end of the second spring 5 away from the positioning plate 11 abuts against the bottom wall of the positioning groove 301.

[0068] like Figure 1 , Figure 2 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further includes a trigger 6, which is rotatably mounted on the mounting base 4. When the trigger 6 rotates under the action of an external force, it can trigger the operating member 3 to control the operation of the operating member 3.

[0069] like Figures 1 to 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting base 1 is provided with a first slide groove 102 along a first direction, the limiting block 2 is slidably disposed in the first slide groove 102, the top wall of the limiting block 2 is provided with a second slide groove 201 along a second direction, the first direction and the second direction intersect, the operating member 3 is provided with a first abutting part 31 at one end near the limiting block 2, at least a portion of the first abutting part 31 extends into the second slide groove 201, the first abutting part 31 is configured to drive the operating member 3 to slide along the first slide groove 102 when sliding along the second slide groove 201 under the action of external force and has at least a locked position and a released position. When the user operates the operating component 3 to move along the second direction, the first abutting part 31 of the operating component 3 will slide along the second slide groove 201. Under the cooperation of the first abutting part 31 and the second slide groove 201 and the restriction of the first slide groove 102, the limiting block 2 can be driven to move along the first direction to the release position to unlock the air nozzle. By adopting the above method, the device avoids excessive clearance space caused by the operation component 3 and the limiting block 2 moving in the same direction, which is conducive to improving the structural compactness of the device.

[0070] like Figure 1 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first spring 4 is disposed in the first slide groove 102, and the end of the first spring 4 away from the limiting block 2 abuts against the inner sidewall of the first slide groove 102. By adopting the above structure, it can be ensured that the first spring 4 can be disposed more stably.

[0071] like Figure 2 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner sidewall of the second slide groove 201 is provided with a first inclined surface 22, the first inclined surface 22 extends towards the first abutting part 31, and the first abutting part 31 is provided with a second inclined surface 311 that abuts and cooperates with the first inclined surface 22. When the first abutting part 31 slides along the second slide groove 201, the cooperation of the first inclined surface 22 and the second inclined surface 311 causes the limiting block 2 to move away from or towards the installation space 101. By adopting the above structure, the first inclined surface 22 and the second inclined surface 311 are kept in tight abutment cooperation under the action of the first spring 4. When the first abutting part 31 moves along the back-and-forth direction of the second slide groove 201, the driving force that drives the first abutting part 31 to move in the second direction can be partially decomposed into a driving force that drives the limiting block 2 to move in the first direction, thereby realizing the direction conversion.

[0072] like Figure 2 , Figure 3 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first inclined surface 22 extends towards the first abutment portion 31 and gradually tilts away from the installation space 101. When the user applies an external force to move the first abutment portion 31 towards the limit block 2, the first inclined surface 22 will slide relative to the second inclined surface 311, causing the limit block 2 to move away from the installation space 101 to the release position.

[0073] like Figure 5 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first limiting rib 12 is provided at the top of the inner wall of the first slide groove 102, the first limiting rib 12 is arranged along the length direction of the first slide groove 102, and a limiting protrusion 23 is formed on the side wall of the limiting block 2, the top wall of the limiting protrusion 23 is slidably connected to the first limiting rib 12. By adopting the above structure, it can be ensured that the limiting block 2 can be securely set in the first slide groove 102, preventing the limiting block 2 from disengaging from the top opening of the first slide groove 102, thereby enabling a more stable locking function for the air injection nozzle.

[0074] like Figure 5 and Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting base 1 has a protrusion forming a third engaging portion 13, the third engaging portion 13 is provided with a second engaging groove, and the first abutting portion 31 is slidably engaged in the second engaging groove. The third engaging portion 13 can form a positioning function. When the first abutting portion 31 is engaged in the second engaging groove, the first abutting portion 31 will slide along the side wall extending direction of the second engaging groove, and at the same time, the top wall of the first abutting portion 31 abuts against the third engaging portion 13, so that the first abutting portion 31 will slide more directionally and prevent the first abutting portion 31 from detaching upwards when sliding.

[0075] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that the first direction is perpendicular to the second direction.

[0076] like Figures 6 to 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting base 1 is provided with a third sliding groove 103, and the top of the inner walls on both sides of the third sliding groove 103 are respectively provided with second limiting ribs 14. The second limiting ribs 14 are arranged along the length direction of the third sliding groove 103. The bottom of the operating member 3 abuts against the top wall of the third sliding groove 103, and the bottom of the operating member 3 forms two buckles 33. The two buckles 33 extend into the third sliding groove 103 and engage with the two second limiting ribs 14 one by one. By adopting the above structure, the bottom of the operating member 3 abuts against the top wall of the third sliding groove 103, thereby facilitating the movement of the first abutting part 31 above the limiting block 2. At the same time, the bottom of the operating member 3 forms two buckles 33 that extend into the third sliding groove 103 and engage with the second limiting ribs 14. The buckles 33 and the second limiting ribs 14 cooperate to limit the operation member 3, so that the operation member 3 will slide along the length direction of the third sliding groove 103 without deviating and is not easy to loosen.

[0077] like Figure 2 , Figure 6 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the operating member 3 has a second abutment portion 34, and a third inclined surface 341 is formed at the end of the second abutment portion near the mounting space 101. The third inclined surface 341 extends in the direction near the mounting space 101 and is configured to slide and connect with the bottom wall of the air nozzle to drive the air nozzle to move upward. By adopting the above structure, when the user operates the operating member 3 to move in the direction near the limiting block 2, the third inclined surface 341 on the second abutment portion 34 will abut and slide against the bottom wall of the air nozzle, thereby driving the limiting block 2 from the locked position to the released position so that the air nozzle is released. At the same time, the second abutment portion 34 can also simultaneously lift the air nozzle upward, making the separation of the air nozzle from the water bottle faster and smoother.

[0078] like Figure 6 and Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the third inclined surface 341 extends toward the mounting space 101 and slopes downward.

[0079] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of limiting blocks 2 is two, and the two limiting blocks 2 are respectively disposed on opposite sides of the installation space 101. The operating component 3 includes an operating rod 32 and two first abutment portions 31. One end of each of the two first abutment portions 31 is connected to the operating rod 32, and the other end of each of the two first abutment portions 31 is respectively connected to the two limiting blocks 2 one-to-one. By setting two limiting blocks 2, they can be respectively engaged with the second locking portions on both sides of the air nozzle, thereby making the air nozzle more stable under force and more secure in installation, greatly reducing the risk of leakage, loosening, and accidents caused by gas pressure impact. Furthermore, the operating component 3 includes two first abutment portions 31, which can simultaneously drive the two limiting blocks 2, thereby improving the unlocking operation speed.

[0080] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the two limiting blocks 2 are symmetrically arranged.

[0081] like Figure 2 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the two first contact portions 31 are symmetrically arranged.

[0082] like Figure 1 and Figure 2 As shown, in addition to the features of the above embodiment, the section of the operating lever 32 away from the first abutment portion 31 abuts against the trigger 6.

[0083] like Figure 1 and Figure 3 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mounting base 1 is provided with a mounting cavity, and the limiting block 2 and the operating component 3 are disposed within the mounting cavity. By providing a mounting cavity on the mounting base 1 for mounting the limiting block 2 and the operating component 3, a protective and dustproof function can be formed, and the sparkling water machine can be made more aesthetically pleasing.

[0084] The second aspect of this application discloses a sparkling water machine.

[0085] like Figures 1 to 10As shown, this embodiment discloses a sparkling water machine, including: a housing assembly 200, the outer side wall of the housing assembly 200 having a recessed accommodating space 202, the accommodating space 202 communicating with the mounting space 101; the aforementioned locking assembly 100, the mounting base 1 being disposed on the housing assembly 200; an air inlet 300, the air inlet 300 being disposed in the mounting space 101; a water bottle 400, the water bottle 400 being detachably disposed in the accommodating space 202, the air inlet end of the water bottle 400 being detachably connected to the air inlet 300; and an air supply device 500, the air supply device 500 communicating with the air inlet 300, the air supply device 500 introducing gas into the water bottle 400 through the air inlet 300. The sparkling water machine disclosed in the second aspect of this application employs the locking assembly 100 of any of the aforementioned claims. Its mounting base 1 is equipped with a limiting block 2 and an operating element 3. The limiting block 2 can form a locking relationship with the air inlet nozzle 300 located in the mounting space 101, thereby ensuring the air inlet nozzle 300 is more securely mounted in the mounting base 1 and safely performing air injection operations. This significantly reduces the risk of leakage, loosening, and accidents caused by gas pressure impacts. After air injection is completed, the user can operate the operating element 3 to move the limiting block 2 to the release position. The limiting block 2 moves away from the mounting space 101 and separates from the air inlet nozzle 300, releasing the locking relationship and allowing the air inlet nozzle 300 to be released and reset.

[0086] like Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air nozzle 300 can extend and retract relative to the accommodating space 202 and has at least a first position and a second position; when the air nozzle 300 is in the first position, it is separated from the air inlet end of the water bottle 400; when the air nozzle 300 is in the second position, it is connected to the air inlet end of the water bottle 400 and can be locked by the limiting block 2; it also includes a rotating pressure rod 600, which is rotatably connected to the mounting base 1 via a rotating shaft. The two ends of the rotating rod 600 are respectively formed with a third abutment portion 610 and a fourth abutment portion 620. The third abutment portion 610 extends into the accommodating space 202. The fourth abutment portion 620 is arranged opposite to the air injection nozzle 300. The water bottle 400 can be detachably connected to the third abutment portion 610. The water bottle 400 can drive the rotating rod 600 to rotate under the action of external force, so that the fourth abutment portion 620 abuts against the air injection nozzle 300 and drives the air injection nozzle 300 to move from the first position to the second position. By setting the rotating pressure rod 600 to be connected to the water bottle 400 and the air nozzle 300 respectively, when the user assembles the water bottle 400 to make sparkling water, the water bottle 400 will be connected to the third abutment part 610 and driven by external force to rotate the rotating pressure rod 600. As a result, the fourth abutment part 620 will be driven to rotate and push the air nozzle 300 to move from the first position to the second position to connect with the air inlet end of the water bottle 400, so that the air supply device 500 can deliver carbon dioxide gas through the air nozzle 300.

[0087] like Figure 4 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air nozzle 300 has a second engaging portion 310, and the first engaging portion 21 of the limiting block 2 can engage with the second engaging portion 310 to restrict and lock the air nozzle 300. Specifically, one of the first engaging portion 21 and the second engaging portion 310 is a protrusion, and the other is a first slot. When the air nozzle 300 is in the second position and the limiting block 2 is in the locked position, the protrusion can engage with the first slot, so that the limiting block 2 restricts and locks the air nozzle 300.

[0088] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0089] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
