Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to 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 main unit into a bottle containing water, turning the water into sparkling water. Currently, many sparkling water makers on the market use screw-on threaded clips or manual alignment of the holes when connecting the water bottle and the nozzle. This is relatively cumbersome and time-consuming, and due to the height limitation of the operating table, users often need to bend over to align the holes, making it inconvenient and negatively impacting the user experience. Utility Model Content

[0003] Therefore, it is necessary to provide a sparkling water machine that addresses the problem that the existing sparkling water machine uses a threaded connection for the water bottle, which is cumbersome and time-consuming, often requiring the user to bend over to align the hole, making it inconvenient to use.

[0004] A sparkling water machine includes: a housing assembly with a recessed accommodating space on its outer side wall; a water bottle detachably disposed within the accommodating space; an air inlet nozzle movably disposed on the housing assembly, the air inlet nozzle being retractable relative to the accommodating space and having at least a first position and a second position, wherein the air inlet nozzle is separated from the air inlet end of the water bottle when in the first position, and connected to the air inlet end of the water bottle when in the second position; and a rotating pressure rod that rotates with the housing assembly via a pivot. The rotating pressure rod has a first abutment and a second abutment at its two ends, with the first abutment extending into the accommodating space and the second abutment facing the air injection nozzle. The water bottle is detachably connected to the first abutment and can be driven to rotate by an external force, so that the second abutment abuts against the air injection nozzle and moves the air injection nozzle from the first position to the second position. A gas supply device is connected to the air injection nozzle and supplies gas to the water bottle through the air injection nozzle.

[0005] This application discloses a sparkling water machine, which includes a rotating pressure rod that is connected to a water bottle and an injection nozzle. When a user assembles the water bottle to make sparkling water, the water bottle connects to the first contact part, and under the action of external force, the rotating pressure rod rotates. This causes the second contact part to rotate and push the injection nozzle from a first position to a second position, connecting it to the air inlet of the water bottle. This allows the gas supply device to deliver carbon dioxide gas through the injection nozzle. By adopting the above structure and utilizing the cooperation of the rotating pressure rod and the injection nozzle, the water bottle and injection nozzle are automatically aligned and connected when the user places it into the first contact part. This is simple and efficient. Since the first contact part is exposed in the accommodating space, the device's visual operation is improved, avoiding the inconvenience of the user bending over to observe the position of the injection nozzle, thus enhancing the user experience.

[0006] In one embodiment, the air inlet is located above the accommodating space, and the air inlet is movable up and down along the height direction of the housing assembly, having at least the first position and the second position. When the air inlet of the water bottle is at its top, during the user's assembly of the water bottle, the water bottle will connect with the first abutment and, under the action of external force, drive the rotating pressure rod to rotate in the vertical plane. This causes the second abutment to rotate downwards and push the air inlet downwards to connect with the air inlet of the water bottle, allowing the gas supply device to deliver carbon dioxide gas through the air inlet.

[0007] In one embodiment, the first abutment portion has a positioning groove on the side near the water bottle, and the water bottle is fitted into the positioning groove. By adopting the above structure, the positioning groove can provide a positioning function, which facilitates the positioning and docking of the water bottle and the first abutment portion. Thus, when the air nozzle moves to the second position, the air inlet end of the water bottle can be aligned and connected with the air nozzle at the same time, and the installation of the water bottle is more secure and less prone to displacement.

[0008] In one embodiment, the second abutment portion includes two abutment arms spaced apart. The bottom walls of the two abutment arms are respectively opposite to the air inlet nozzle. When the water bottle drives the rotating pressure rod to rotate under external force, the two abutment arms respectively abut against the two ends of the air inlet nozzle and drive the air inlet nozzle to move from the first position to the second position. By adopting the above structure, when the water bottle drives the rotating pressure rod to rotate under external force, the two abutment arms abut against the two ends of the air inlet nozzle, thereby making the air inlet nozzle more stable under force. At the same time, a clearance space is formed between the two abutment arms, so that the air inlet end of the air inlet nozzle can pass through the clearance space and connect to the air supply device through the conduit, making the internal structure of the device more compact.

[0009] In one embodiment, the sidewall of the air nozzle has a protruding abutment shaft, and the second abutment portion has an arc surface near the abutment shaft. The arc surface is positioned opposite to the abutment shaft. When the water bottle drives the rotating pressure rod to rotate under external force, the arc surface slides in connection with the peripheral wall of the abutment shaft. By adopting the above structure, when the arc surface abuts against the abutment shaft and drives the air nozzle to move from the first position to the second position, the abutment shaft can slide along the arc surface with the cooperation of the arc surface and the peripheral wall of the abutment shaft. This makes the extension and retraction of the air nozzle smoother and less prone to tilting.

[0010] In one embodiment, the rotating pressure rod includes a rotating body, a first abutment portion, and a second abutment portion. The rotating body is rotatably connected to the housing assembly via a rotating shaft, the axis of which is perpendicular to the extension / retraction direction of the air inlet. The first abutment portion extends from the bottom wall of the rotating body toward the accommodating space, and the second abutment portion extends from the side wall of the rotating body toward the air inlet. The bottom wall of the second abutment portion is opposite to the air inlet. With this structure, during the user's assembly of the water bottle, the water bottle will connect to the first abutment portion and, under external force, drive the rotating body to rotate in a vertical plane. This causes the second abutment portion to rotate downwards, pushing the air inlet downwards to connect with the air inlet of the water bottle, allowing the air supply device to deliver carbon dioxide gas through the air inlet.

[0011] In one embodiment, the rotating shaft is disposed on the rotating body, and the housing assembly has a positioning part with a shaft hole, into which the rotating shaft is rotatably engaged. The positioning part facilitates the positioning and installation of the rotating body, and the engaging fit between the rotating shaft and the shaft hole enables quick connection between the rotating shaft and the positioning part.

[0012] In one embodiment, the rotating shaft has a first inclined surface on the side near the shaft hole.

[0013] In one embodiment, the positioning part has a second inclined surface on the side near the rotating shaft. The first and / or second inclined surfaces allow the rotating shaft or positioning part to be deformed by compression during installation into the shaft hole, thereby reducing the difficulty of the snap-fit ​​operation and facilitating installation.

[0014] In one embodiment, the top wall of the rotating body is provided with a groove. This makes the rotating body form a hollow structure to facilitate elastic deformation.

[0015] In one embodiment, there are two rotating shafts, which are respectively disposed at both ends of the rotating body.

[0016] In one embodiment, the rotating shaft is integrally formed with the rotating body or the housing assembly.

[0017] In one embodiment, a first spring is also included. One end of the first spring abuts against the housing assembly, and the other end abuts against the rotating pressure rod or the air nozzle. When the air nozzle moves from the first position to the second position, the first spring deforms and accumulates elastic force to drive the air nozzle back from the second position to the first position. With the first spring, when the water bottle leaves the accommodating space, the pushing force on the rotating pressure rod and the air nozzle disappears, and the first spring quickly and elastically returns to its original position, driving the air nozzle and the rotating pressure rod back to their original positions for the next use, simplifying user operation. Furthermore, the first spring provides resistance, thereby preventing the first abutment from being triggered unintentionally to some extent.

[0018] In one embodiment, the housing assembly has a first limiting post, and the first spring is sleeved on the outside of the first limiting post, with both ends of the first spring abutting against the housing assembly and the air injection nozzle, respectively. Forming the first limiting post on the housing assembly facilitates the limiting setting of the first spring, making installation convenient while effectively preventing the first spring from detaching during extension and retraction.

[0019] In one embodiment, a locking assembly is further included. The locking assembly is disposed on the housing assembly and has a first engaging portion. The air nozzle has a second engaging portion. The first engaging portion engages with the second engaging portion to lock and restrict the air nozzle. By using the locking assembly, when the air nozzle is in the second position, the second engaging portion of the air nozzle engages with the first engaging portion of the locking assembly, further limiting the air nozzle's position. This effectively ensures that the air nozzle is securely installed when connected to the gas supply device to fill the water bottle, preventing it from loosening due to gas pressure impact and causing an accident.

[0020] In one embodiment, the locking assembly includes an operating member and a limiting block. The limiting block has a first engaging portion and is movably disposed on the housing assembly, having at least a locked position and a released position. When the limiting block is in the locked position, the second engaging portion engages with the first engaging portion. When the limiting block is in the released position, the second engaging portion is moved away from the first engaging portion. The operating member is movably disposed on the housing assembly and is drively connected to the limiting block. The operating member can drive the limiting block to move from the locked position to the released position under external force. By adopting the above structure, when the air nozzle is in the second position, the second engaging portion of the air nozzle engages with the first engaging portion on the limiting block to form a locking relationship, thereby enabling the air nozzle to carry out air injection operations more reliably and safely. After air injection is completed, the user can drive the limiting block to the released position by operating the operating member, thereby separating the first engaging portion from the locking block, releasing the locking relationship, separating the air nozzle from the locking assembly, and allowing it to reset from the second position to the first position.

[0021] In one embodiment, the locking assembly further includes a second spring, the two ends of which abut against the limiting block and the housing assembly, respectively. When the limiting block moves from the locked position to the released position, the second spring deforms and accumulates elastic force to drive the limiting block back from the released position to the locked position. With the second spring, when the external force applied by the user to the operating component disappears, the second 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 second spring can provide a certain limiting effect 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 engages with the first locking part on the limiting block.

[0022] In one embodiment, the locking assembly further includes a third spring, the two ends of which abut against the operating member and the housing assembly, respectively. When the limiting block is in the released position, the third spring deforms. By providing the third spring, when the external force applied by the user to the operating member disappears, the third spring will quickly and elastically return to its original position, driving the operating member to reset for the next use, thus simplifying user operation.

[0023] In one embodiment, the housing assembly has 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 has a second groove along a second direction, the first direction intersecting the second direction. The operating member has a third abutment at one end near the limiting block, at least a portion of which extends into the second groove. The third abutment is configured to drive the operating member to slide along the first groove when sliding along the second groove 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 third abutment of the operating member will slide along the second groove. Under the cooperation of the third abutment 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.

[0024] In one embodiment, the inner wall of the second slide groove is provided with a third inclined surface, which extends towards the third abutment portion. The third abutment portion is provided with a fourth inclined surface that abuts against the third inclined surface. When the third abutment portion slides along the second slide groove, the engagement of the third and fourth inclined surfaces causes the limiting block to move away from or towards the air injection nozzle. By adopting the above structure, the third and fourth inclined surfaces maintain a tight abutment engagement under the action of the second spring. When the third abutment portion moves along the front-back direction of the second slide groove, the driving force that drives the third abutment 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.

[0025] In one embodiment, the third inclined surface extends toward the third abutment and gradually slopes away from the air nozzle. When the user applies an external force to move the third abutment toward the limiting block, the third inclined surface slides relative to the fourth inclined surface, causing the limiting block to move away from the air nozzle to the release position.

[0026] In one embodiment, the operating member has a fourth abutment portion, and a fifth inclined surface is formed at the end of the fourth abutment portion near the air nozzle. The fifth inclined surface extends in the direction near the air nozzle and is configured to slide with the side of the air nozzle near the receiving space to drive the air nozzle upward. With this structure, when the user operates the operating member to move towards the limiting block, the fifth inclined surface on the fourth abutment portion will abut 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 fourth abutment portion can also raise the air nozzle upward, making the separation of the air nozzle from the water bottle faster and smoother.

[0027] In one embodiment, the locking assembly further includes a trigger rotatably mounted on the housing assembly, which, when rotated under external force, can actuate the operating element to control its movement.

[0028] In one embodiment, the housing assembly has a mounting cavity. The side wall of the mounting cavity has a first limiting hole and a clearance opening, both communicating with the accommodating space. The rotating pressure rod and the air nozzle are movably disposed within the mounting cavity. The air outlet end of the air nozzle is movably inserted into the first limiting hole, and one end of the first abutment portion extends into the accommodating space through the clearance opening. By providing a mounting cavity on the housing assembly for mounting the rotating pressure rod and the air nozzle, a protective dustproof function can be formed, and the aesthetics of the sparkling water machine can be improved. When the rotating pressure rod rotates, causing the second abutment portion to abut against the air nozzle and push the air nozzle to move to the second position, the air outlet end of the air nozzle will move axially along the first limiting hole under the restriction of the first limiting hole and connect to the air inlet end of the water bottle through the first limiting hole. This ensures that the air nozzle extends and retracts in a directional manner and operates stably.

[0029] In one embodiment, the mounting cavity has a first limiting post formed on the side wall near the accommodating space, and the first limiting post has a first limiting hole.

[0030] In one embodiment, a boss is formed on the peripheral wall of the air nozzle, and the boss has a second limiting hole. A second limiting post is formed on the side of the housing assembly away from the accommodating space, and the second limiting post is movably inserted into the second limiting hole. By adopting the above structure, when the rotating pressure rod rotates to make the second abutting part abut against the air nozzle and push the air nozzle to move to the second position, the second limiting hole and the second limiting post will cooperate to form a limiting effect, so that the air nozzle will move along the length direction of the second limiting post, thereby ensuring the directional extension and retraction of the air nozzle and stable operation.

[0031] In one embodiment, there are multiple second limiting holes, which are spaced apart circumferentially along the boss. The number of second limiting posts is the same as the number of second limiting holes, and they are arranged in a one-to-one correspondence. By cooperating with the multiple second limiting holes and multiple second limiting posts, the positioning and assembly of the air injection nozzle can be facilitated, thereby improving installation efficiency.

Detailed Implementation

[0051] 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.

[0052] 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.

[0053] The following describes some embodiments of the sparkling water machine according to the present invention with reference to the accompanying drawings.

[0054] like Figures 1 to 4 As shown, this embodiment discloses a sparkling water machine, including: a housing assembly 1, the outer side wall of which is recessed with an accommodating space 101; a water bottle 2, which is detachably disposed in the accommodating space 101; an air inlet 3, which is movably disposed on the housing assembly 1, and is capable of telescoping relative to the accommodating space 101 and has at least a first position and a second position. When the air inlet 3 is in the first position, it is separated from the air inlet end of the water bottle 2, and when the air inlet 3 is in the second position, it is connected to the air inlet end of the water bottle 2; and a rotating pressure rod 4, which is connected to the water bottle 2 via a rotating shaft 5. The housing assembly 1 is rotatably connected, and the two ends of the rotating pressure rod 4 form a first abutment part 41 and a second abutment part 42 respectively. The first abutment part 41 extends into the accommodating space 101, and the second abutment part 42 is disposed opposite to the air injection nozzle 3. The water bottle 2 is detachably connected to the first abutment part 41. The water bottle 2 can drive the rotating pressure rod 4 to rotate under the action of external force, so that the second abutment part 42 abuts against the air injection nozzle 3 and drives the air injection nozzle 3 to move from the first position to the second position. The air supply device 6 is connected to the air injection nozzle 3, and the air supply device 6 introduces gas into the water bottle 2 through the air injection nozzle 3.

[0055] This application discloses a sparkling water machine, which includes a rotating pressure rod 4 that is connected to a water bottle 2 and an air nozzle 3. When the user assembles the water bottle 2 to make sparkling water, the water bottle 2 connects to the first abutment part 41 and, under the action of external force, drives the rotating pressure rod 4 to rotate. This causes the second abutment part 42 to rotate and push the air nozzle 3 from a first position to a second position, connecting it to the air inlet of the water bottle 2. This allows the air supply device 6 to deliver carbon dioxide gas through the air nozzle 3. By adopting the above structure, and utilizing the cooperation of the rotating pressure rod 4 and the air nozzle 3, the water bottle 2 and the air nozzle 3 can be automatically aligned and connected when the user places the water bottle 2 into the first abutment part 41. This is simple and efficient. Since the first abutment part 41 is exposed in the accommodating space 101, the visual operation of the device is improved, avoiding the inconvenience of the user bending over to observe the position of the air nozzle 3, thus improving the user experience.

[0056] like Figures 1 to 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the air inlet 3 is located above the accommodating space 101, and the air inlet 3 can move up and down along the height direction of the housing assembly 1 and has at least a first position and a second position. When the air inlet end of the water bottle 2 is located at its top, during the user's assembly of the water bottle 2, the water bottle 2 will be connected to the first abutment part 41 and driven by external force to rotate the rotating pressure rod 4 in the vertical plane. As a result, the second abutment part 42 will be driven to rotate downward and push the air inlet 3 downward to connect with the air inlet end of the water bottle 2, so that the gas supply device 6 can deliver carbon dioxide gas through the air inlet 3.

[0057] like Figure 1 and Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the first abutment portion 41 has a positioning groove 401 on the side near the water bottle 2, and the water bottle 2 is fitted and installed in accordance with the positioning groove 401. By adopting the above structure, the positioning groove 401 can play a positioning role, which can facilitate the positioning and docking of the water bottle 2 and the first abutment portion 41. Thus, when the air nozzle 3 moves to the second position, the air inlet end of the water bottle 2 can be aligned and connected with the air nozzle 3 at the same time, and the installation of the water bottle 2 is more secure and less prone to displacement.

[0058] like Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second abutment part 42 includes two abutment arms 421, which are spaced apart. The bottom walls of the two abutment arms 421 are respectively opposite to the air inlet nozzle 3. When the water bottle 2 drives the rotating pressure rod 4 to rotate under the action of external force, the two abutment arms 421 respectively abut against the two ends of the air inlet nozzle 3 and drive the air inlet nozzle 3 to move from the first position to the second position. By adopting the above structure, when the water bottle 2 drives the rotating pressure rod 4 to rotate under the action of external force, the two abutment arms 421 respectively abut against the two ends of the air inlet nozzle 3, thereby making the air inlet nozzle 3 more stable under force. At the same time, a clearance space is formed between the two abutment arms 421, so that the air inlet end of the air inlet nozzle 3 can pass through the clearance space and connect to the air supply device 6 through the conduit, making the internal structure of the device more compact.

[0059] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the side wall of the air nozzle 3 has a protruding abutment shaft 31, and the second abutment portion 42 has an arc surface 422 formed on the side near the abutment shaft 31. The arc surface 422 is disposed opposite to the abutment shaft 31. When the water bottle 2 drives the rotating pressure rod 4 to rotate under the action of external force, the arc surface 422 is slidably connected to the peripheral wall of the abutment shaft 31. By adopting the above structure, when the arc surface 422 abuts against the abutment shaft 31 and drives the air nozzle 3 to move from the first position to the second position, the abutment shaft 31 can slide along the arc surface 422 under the cooperation of the arc surface 422 and the peripheral wall of the abutment shaft 31, thereby making the extension and retraction of the air nozzle 3 smoother and less prone to tilting.

[0060] like Figure 3 , Figure 4 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further defines: the rotating pressure rod 4 includes a rotating body 43, a first abutment part 41, and a second abutment part 42. The rotating body 43 is rotatably connected to the housing assembly 1 via a rotating shaft 5. The axis of the rotating shaft 5 is perpendicular to the extension and retraction direction of the air inlet 3. The first abutment part 41 extends from the bottom wall of the rotating body 43 toward the direction close to the accommodating space 101, and the second abutment part 42 extends from the side wall of the rotating body 43 toward the direction close to the air inlet 3. The bottom wall of the second abutment part 42 is disposed opposite to the air inlet 3. By adopting the above structure, during the user's assembly of the water bottle 2, the water bottle 2 will be connected to the first abutment part 41 and can be driven by external force to rotate the rotating body 43 in the vertical plane. As a result, the second abutment part 42 will be driven to rotate downward and push the air inlet 3 to move downward and connect with the air inlet end of the water bottle 2, so that the gas supply device 6 can deliver carbon dioxide gas through the air inlet 3.

[0061] like Figure 2 and Figure 6As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the rotating shaft 5 is disposed on the rotating body 43, the housing assembly 1 has a positioning part 11, the positioning part 11 has a shaft hole, and the rotating shaft 5 is rotatably engaged in the shaft hole. The positioning part 11 facilitates the positioning and installation of the rotating body 43, and the engaging fit between the rotating shaft 5 and the shaft hole enables a quick connection between the rotating shaft 5 and the positioning part 11.

[0062] like Figure 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the rotating shaft 5 is provided with a first inclined surface 51 on the side near the shaft hole.

[0063] like Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the positioning part 11 is provided with a second inclined surface 111 on the side near the rotating shaft 5. The provision of the first inclined surface 51 and / or the second inclined surface 111 allows the rotating shaft 5 or the positioning part 11 to be squeezed and deformed under the action of the first inclined surface 51 and the second inclined surface 111 during the process of installing the rotating shaft 5 into the shaft hole, thereby reducing the difficulty of the snap-fit ​​operation and making the installation smooth.

[0064] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the top wall of the rotating body 43 is provided with a groove 402. This makes the rotating body 43 form a hollow structure to facilitate elastic deformation.

[0065] like Figure 8 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of rotating shafts 5 is two, and the two rotating shafts 5 are respectively arranged at both ends of the rotating body 43.

[0066] like Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the rotating shaft 5 and the rotating body 43 or the housing assembly 1 are integrally formed.

[0067] like Figure 3 and Figure 4As shown, in addition to the features of the above embodiments, this embodiment further includes a first spring 7. One end of the first spring 7 abuts against the housing assembly 1, and the other end of the first spring 7 abuts against the rotating pressure rod 4 or the air nozzle 3. When the air nozzle 3 moves from the first position to the second position, the first spring 7 deforms and accumulates elastic force to drive the air nozzle 3 back from the second position to the first position. With the first spring 7, when the water bottle 2 leaves the accommodating space 101, the pushing force on the rotating pressure rod 4 and the air nozzle 3 disappears, and the first spring 7 quickly and elastically recovers, driving the air nozzle 3 and the rotating pressure rod 4 back to their original positions for the next round of use, simplifying user operation. Furthermore, the first spring 7 can form resistance, thereby preventing the first abutment part 41 from being triggered unintentionally to a certain extent.

[0068] like Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 has a first limiting post 12, and the first spring 7 is sleeved on the outside of the first limiting post 12, with both ends of the first spring 7 abutting against the housing assembly 1 and the air inlet 3, respectively. By forming the first limiting post 12 on the housing assembly 1, the limiting setting of the first spring 7 can be facilitated, making installation convenient while effectively preventing the first spring 7 from detaching during its extension and retraction.

[0069] like Figure 5 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further includes a locking component 8, which is disposed on the housing assembly 1. The locking component 8 has a first engaging portion 821, and the air nozzle 3 has a second engaging portion 32. The first engaging portion 821 can engage with the second engaging portion 32 to lock and restrict the air nozzle 3. By setting the locking component 8, when the air nozzle 3 is in the second position, the second engaging portion 32 of the air nozzle 3 engages with the first engaging portion 821 on the locking component 8, thereby further limiting the air nozzle 3. This effectively ensures that the air nozzle 3 can be securely installed when connected to the gas supply device 6 to inject gas into the water bottle 2, and will not loosen due to gas pressure impact, thus preventing accidents.

[0070] like Figures 5 to 9As shown, in addition to the features of the above embodiments, this embodiment further defines: the locking component 8 includes an operating member 81 and a limiting block 82. The limiting block 82 is provided with a first engaging portion 821. The limiting block 82 is movably disposed on the housing component 1 and has at least a locked position and a released position. When the limiting block 82 is in the locked position, the second engaging portion 32 can engage with the first engaging portion 821. When the limiting block 82 is in the released position, the second engaging portion 32 is away from the first engaging portion 821. The operating member 81 is movably disposed on the housing component 1 and is connected to the limiting block 82 in a transmission manner. The operating member 81 can drive the limiting block 82 to move from the locked position to the released position under the action of an external force. By adopting the above structure, when the air nozzle 3 is in the second position, the second locking part 32 of the air nozzle 3 engages with the first locking part 821 on the limiting block 82 to form a locking relationship, so that the air nozzle 3 can carry out the air injection operation more reliably and safely. After the air injection is completed, the user can drive the limiting block 82 to the release position by operating the operating member 81. As a result, the first locking part 821 separates from the locking block, thereby releasing the locking relationship. The air nozzle 3 separates from the locking assembly 8 and can be reset from the second position to the first position.

[0071] like Figure 5 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the locking assembly 8 also includes a second spring 83, the two ends of the second spring 83 abutting against the limiting block 82 and the housing assembly 1 respectively. When the limiting block 82 moves from the locked position to the released position, the second spring 83 deforms and accumulates elastic force to drive the limiting block 82 to reset from the released position to the locked position. With the setting of the second spring 83, when the external force applied by the user to the operating member 81 disappears, the second spring 83 will quickly and elastically recover and drive the limiting block 82 and the operating member 81 to reset for the next round of use, simplifying the user's operation; in addition, the second spring 83 can form a certain limiting effect on the limiting block 82, preventing the limiting block 82 from disengaging from the locked position and causing the locking function to fail when the second latching part 32 of the air nozzle 3 latches with the first latching part 821 on the limiting block 82.

[0072] like Figure 3 and Figure 7 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the locking assembly 8 also includes a third spring 84, the two ends of which abut against the operating member 81 and the housing assembly 1 respectively. When the limiting block 82 is in the released position, the third spring 84 deforms. With the third spring 84, when the external force applied by the user to the operating member 81 disappears, the third spring 84 will quickly and elastically return to its original position and drive the operating member 81 to reset for the next round of use, simplifying user operation.

[0073] like Figures 5 to 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a first slide groove 105 along a first direction, the limiting block 82 is slidably disposed in the first slide groove 105, the top wall of the limiting block 82 is provided with a second slide groove 801 along a second direction, the first direction and the second direction intersect, the operating member 81 near the end of the limiting block 82 is provided with a third abutment portion 811, at least a portion of the third abutment portion 811 extends into the second slide groove 801, the third abutment portion 811 is configured to drive the operating member 81 to slide along the first slide groove 105 when sliding along the second slide groove 801 under the action of external force and has at least a locked position and a released position. When the user operates the operating component 81 to move along the second direction, the third abutment part 811 of the operating component 81 will slide along the second slide groove 801. Under the cooperation of the third abutment part 811 and the second slide groove 801 and the restriction of the first slide groove 105, the limiting block 82 can be driven to move along the first direction to the release position to unlock the air nozzle 3. By adopting the above method, the device avoids excessive clearance space caused by the operation component 81 and the limiting block 82 moving in the same direction, which is conducive to improving the structural compactness of the device.

[0074] like Figures 6 to 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the inner wall of the second slide groove 801 is provided with a third inclined surface 822, the third inclined surface 822 extends towards the third abutment portion 811, and the third abutment portion 811 is provided with a fourth inclined surface 8111 that abuts and cooperates with the third inclined surface 822. When the third abutment portion 811 slides along the second slide groove 801, the cooperation between the third inclined surface 822 and the fourth inclined surface 8111 causes the limiting block 82 to move away from or towards the air injection nozzle 3. By adopting the above structure, the third inclined surface 822 and the fourth inclined surface 8111 maintain a tight abutment cooperation under the action of the second spring 83. When the third abutment portion 811 moves along the back-and-forth direction of the second slide groove 801, the driving force that drives the third abutment portion 811 to move in the second direction can be partially decomposed into a driving force that drives the limiting block 82 to move in the first direction, thereby realizing a direction change.

[0075] like Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the third inclined surface 822 extends towards the third abutment portion 811 and gradually tilts away from the air nozzle 3. When the user applies an external force to move the third abutment portion 811 towards the limit block 82, the third inclined surface 822 will slide relative to the fourth inclined surface 8111, causing the limit block 82 to move away from the air nozzle 3 to the release position.

[0076] like Figures 8 to 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the operating member 81 has a fourth abutment portion 812, and a fifth inclined surface 8121 is formed at the end of the fourth abutment portion 812 near the air nozzle 3. The fifth inclined surface 8121 extends in the direction near the air nozzle 3 and is configured to slide and connect with the side of the air nozzle 3 near the receiving space 101 to drive the air nozzle 3 to move upward. By adopting the above structure, when the user operates the operating member 81 to move in the direction near the limiting block 82, the fifth inclined surface 8121 on the fourth abutment portion 812 will abut and slide against the bottom wall of the air nozzle 3, thereby driving the limiting block 82 from the locked position to the released position so that the air nozzle 3 is released. At the same time, the fourth abutment portion 812 can also simultaneously lift the air nozzle 3 upward, making the separation of the air nozzle 3 from the water bottle 2 faster and smoother.

[0077] like Figures 6 to 8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the locking assembly 8 also includes a trigger 85, which is rotatably disposed on the housing assembly 1. When the trigger 85 rotates under the action of an external force, it can actuate the operating member 81 to control the operation of the operating member 81.

[0078] like Figure 1 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the housing assembly 1 is provided with a mounting cavity 102, the side wall of the mounting cavity 102 is provided with a first limiting hole 103 and a clearance port 104 that are both connected to the accommodating space 101, the rotating pressure rod 4 and the air injection nozzle 3 are respectively movably disposed in the mounting cavity 102, the air outlet end of the air injection nozzle 3 is movably inserted into the first limiting hole 103, and one end of the first abutting part 41 extends into the accommodating space 101 through the clearance port 104. By providing a mounting cavity 102 on the housing assembly 1 for mounting the rotating pressure rod 4 and the air nozzle 3, a protective dustproof function can be formed, and the aesthetics of the sparkling water machine can be improved. When the rotating pressure rod 4 rotates, causing the second abutment part 42 to abut against the air nozzle 3 and push the air nozzle 3 to move to the second position, the air outlet end of the air nozzle 3 will move along the axial direction of the first limiting hole 103 under the restriction of the first limiting hole 103 and connect to the air inlet end of the water bottle 2 through the first limiting hole 103. This ensures that the air nozzle 3 can extend and retract in a directional manner and work stably.

[0079] like Figure 3 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first limiting post 12 is formed on the side wall of the mounting cavity 102 near the accommodating space 101, and the first limiting post 12 is provided with a first limiting hole 103.

[0080] like Figure 9 and Figure 10As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a boss 33 is formed on the peripheral wall of the air nozzle 3, the boss 33 is provided with a second limiting hole 301, and a second limiting post 13 is formed on the side of the housing assembly 1 away from the accommodating space 101, the second limiting post 13 being movably inserted into the second limiting hole 301. By adopting the above structure, when the rotating pressure rod 4 rotates to make the second abutting part 42 abut against the air nozzle 3 and push the air nozzle 3 to move to the second position, the second limiting hole 301 and the second limiting post 13 cooperate to form a limiting effect, so that the air nozzle 3 will move along the length direction of the second limiting post 13, thereby ensuring that the air nozzle 3 extends and retracts in a directional manner and works stably.

[0081] like Figure 9 and Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the number of second limiting holes 301 is multiple, the multiple second limiting holes 301 are arranged at intervals along the circumference of the boss 33, and the number of second limiting posts 13 is the same as that of the second limiting holes 301 and they are arranged in a one-to-one correspondence. By cooperating with the multiple second limiting holes 301 and the multiple second limiting posts 13, the positioning and assembly of the air injection nozzle 3 can be facilitated, thereby improving the installation efficiency.

[0082] 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.

[0083] 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.
